- Abstract
The objective of this study is to utilize optical coherence tomography angiography (OCTA) techniques for the purpose of identifying abnormalities in retinal and conjunctival vascular density among patients afflicted with renal hypertension. From October 2022 to October 2023, a cohort of sixteen patients diagnosed with renal hypertension (RH), comprising a total of 32 eyes, was selected from the Department of Nephrology at the First Affiliated Hospital of Nanchang University. Concurrently, a group of sixteen healthy individuals, carefully matched in characteristics, was recruited from volunteers at the Ophthalmology Research Center and designated as the healthy controls (HCs) group. Optical coherence tomography angiography was employed to assess and examine the superficial vascular plexus (SVP) and deep vascular plexus (DVP) of the macular retina in both eyes. Subsequently, a comparative analysis was conducted between the two groups, focusing on the superficial and deep retinal microvessels (MIR), macrovascular (MAR), and total microvascular (TMI). The present study employed the central annuli segmentation method (C1-C6), the hemispheric segmentation method (SL, IL, SR, IR), and the Early Treatment Diabetic Retinopathy Study (S, I, L, R) to evaluate deviations in retinal blood vessel density. The investigation aimed to examine the association between blood vessel density and TMI in conjunctival capillaries. A statistically significant difference (p < 0.05) in macular retinal vascular density was observed between the two groups based on the OCTA data. Specifically, in SVP, the density of TMI, MIR, and MAR in the RH group was significantly lower compared to the HCs group (p < 0.05). Additionally, the deep density of TMI and MIR in DVP of the RH group was significantly lower than that of the HCs group (p < 0.05). Furthermore, using the hemispheric segmentation method, both the superficial and deep retina showed a significant reduction in the density of SL, SR and IL regions (p < 0.05). In the ETDRS method, there was a significant decrease in superficial and deep retinal S, I, and L in the RH group (p < 0.05). When applying the central annuli segmentation methods, the RH group exhibited a significant decrease in the superficial retinal C1-3 region (p < 0.05) and a noticeable reduction in the deep retina in the C1-4 region (p < 0.05). Furthermore, a higher positive likelihood ratio was observed in the deep SL and superficial C2 region. There was a positive correlation between conjunctival capillary density and the region of TMI in depth. The results of the OCTA investigation revealed a significant disparity in the density of superficial and deep retinal blood vessels between RH group and the HCs group. Additionally, a notable correlation was observed between the depth of TMI and the density of conjunctival capillaries. These findings highlight the potential of retinal OCTA as a valuable tool for early detection and image-assisted diagnosis of retinopathy progression in patients with RH., Competing Interests: Competing interests: The authors declare no competing interests., (© 2024.

- Abstract
Aim: To examine the disparities in macular retinal vascular density between individuals with connective tissue disease-related interstitial lung disease (CTD-ILD) and healthy controls (HCs) by optical coherence tomography angiography (OCTA) and to investigate the changes in microvascular density in abnormal eyes., Methods: For a retrospective case-control study, a total of 16 patients (32 eyes) diagnosed with CTD-ILD were selected as the ILD group. The 16 healthy volunteers with 32 eyes, matched in terms of age and sex with the patients, were recruited as control group. The macular retina's superficial retinal layer (SRL) and deep retinal layer (DRL) were examined and scanned using OCTA in each individual eye. The densities of retinal microvascular (MIR), macrovascular (MAR), and total microvascular (TMI) were calculated and compared. Changes in retinal vascular density in the macular region were analyzed using three different segmentation methods: central annuli segmentation method (C1-C6), hemispheric segmentation method [uperior right (SR), superior left (SL), inferior left (IL), and inferior right (IR)], and Early Treatment Diabetic Retinopathy Study (ETDRS) methods [superior (S), inferior (I), left (L), and right (R)]. The data were analyzed using Version 9.0 of GraphPad prism and Pearson analysis., Results: The OCTA data demonstrated a statistically significant difference ( P <0.05) in macular retinal microvessel density between the two groups. Specifically, in the SRL and DRL analyses, the ILD group exhibited significantly lower surface density of MIR and TMI compared to the HCs group ( P <0.05). Furthermore, using the hemispheric segmentation method, the ILD group showed notable reductions in SL, SR, and IL in the superficial retina ( P <0.05), as well as marked decreases in SL and IR in the deep retina ( P <0.05). Similarly, when employing the ETDRS method, the ILD group displayed substantial drops in superficial retinal S and I ( P <0.05), along with notable reductions in deep retinal L, I, and R ( P <0.05). In the central annuli segmentation method, the ILD group exhibited a significant decrease in the superficial retinal C2-4 region ( P <0.05), whereas the deep retina showed a notable reduction in the C3-5 region ( P <0.05). Additionally, there was an observed higher positive likelihood ratio in the superficial SR region and deep MIR. Furthermore, there was a negative correlation between conjunctival vascular density and both deep and superficial retinal TMI ( P <0.001)., Conclusion: Patients with CTD-ILD exhibits a significantly higher conjunctival vascular density compared to the HCs group. Conversely, their fundus retinal microvascular density is significantly lower. Furthermore, CTD-ILD patients display notably lower superficial and deep retinal vascular density in comparison to the HCs group. The inverse correlation between conjunctival vascular density and both superficial and deep retinal TMI suggests that detecting subtle changes in ocular microcirculation could potentially serve as an early diagnostic indicator for connective tissue diseases, thereby enhancing disease management., Competing Interests: Conflicts of Interest: Chen LM, None; Kang M, None; Wang JY, None; Xu SH, None; Chen C, None; Wei H, None; Ling Q, None; He LQ, None; Zou J, None; Wang YX, None; Chen X, None; Ying P, None; Huang H, None; Shao Y, None; Wu R, None., (International Journal of Ophthalmology Press.)

- Abstract
Aim: To study functional brain abnormalities in patients with hypertensive retinopathy (HR) and to discuss the pathophysiological mechanisms of HR by fractional amplitude of low-frequency fluctuations (fALFFs) method., Methods: Twenty HR patients and 20 healthy controls (HCs) were respectively recruited. The age, gender, and educational background characteristics of the two groups were similar. After functional magnetic resonance imaging (fMRI) scanning, the subjects' spontaneous brain activity was evaluated with the fALFF method. Receiver operating characteristic (ROC) curve analysis was used to classify the data. Further, we used Pearson's correlation analysis to explore the relationship between fALFF values in specific brain regions and clinical behaviors in patients with HR., Results: The brain areas of the HR group with lower fALFF values than HCs were the right orbital part of the middle frontal gyrus (RO-MFG) and right lingual gyrus. In contrast, the values of fALFFs in the left middle temporal gyrus (MTG), left superior temporal pole (STP), left middle frontal gyrus (MFG), left superior marginal gyrus (SMG), left superior parietal lobule (SPL), and right supplementary motor area (SMA) were higher in the HR group. The results of a t -test showed that the average values of fALFFs were statistically significantly different in the HR group and HC group ( P <0.001). The fALFF values of the left middle frontal gyrus in HR patients were positively correlated with anxiety scores ( r =0.9232; P <0.0001) and depression scores ( r =0.9682; P <0.0001)., Conclusion: fALFF values in multiple brain regions of HR patients are abnormal, suggesting that these brain regions in HR patients may be dysfunctional, which may help to reveal the pathophysiological mechanisms of HR., Competing Interests: Conflicts of Interest: Wang XL, None; Zheng XJ, None; Zhang LJ, None; Hu JY, None; Wei H, None; Ling Q, None; He LQ, None; Chen C, None; Wang YX, None; Chen X, None; Shao Y, None., (International Journal of Ophthalmology Press.)

- Abstract
Background: There have been only few reports on Rhupus syndrome with severe visceral involvement. Moreover, there was little consensus regarding its treatment. Belimumab is one of the options for treating this disease. For patients with clinical symptoms and elevated levels of anti CCP antibodies and anti-double stranded DNA antibodies, and it suggests Rhupus syndrome. After effective treatment, the decrease in levels of anti CCP antibodies and anti-double stranded DNA (ds-DNA) antibodies can effectively delay the progression of the disease and protect target organs., Methods: We used a chemiluminescence instrument, (Yahuilong; Shenzhen, China), to measure the changes in CCP and dsDNA before and after treatment., Results: Prior to treatment, the patient presented with symptoms of rheumatoid arthritis and systemic lupus erythematosus. Her laboratory tests showed dsDNA (214 IU/mL) and CCP level of ˃ 3,000 U/mL. After treatment with belimumab, the clinical symptoms were significantly relieved, and the patient's CCP IgG level decreased to 263.5 U/mL. A blood test found that her anti-dsDNA was negative., Conclusions: CCP and dsDNA can serve as indicators for the diagnosis and treatment of Rhupus syndrome.

- Abstract
Acute pancreatitis, a common exocrine inflammatory disease affecting the pancreas, is characterized by intense abdominal pain and multiple organ dysfunction. However, the alterations in retinal blood vessels among individuals with acute pancreatitis remain poorly understood. This study employed optical coherence tomography angiography (OCTA) to examine the superficial and deep retinal blood vessels in patients with pancreatitis. Sixteen patients diagnosed with pancreatitis (32 eyes) and 16 healthy controls (32 eyes) were recruited from the First Affiliated Hospital of Nanchang University for participation in the study. Various ophthalmic parameters, such as visual acuity, intraocular pressure, and OCTA image for retina consisting of the superficial retinal layer (SRL) and the deep retinal layer (DRL), were recorded for each eye. The study observed the superficial and deep retinal microvascular ring (MIR), macrovascular ring (MAR), and total microvessels (TMI) were observed. Changes in retinal vascular density in the macula through annular partitioning (C1-C6), hemispheric quadrant partitioning (SR, SL, IL, and IR), and early diabetic retinopathy treatment studies (ETDRS) partitioning methods (R, S, L, and I). Correlation analysis was employed to investigate the relationship between retinal capillary density and clinical indicators. Our study revealed that in the superficial retinal layer, the vascular density of TMI, MIR, MAR, SR, IR, S, C2, C3 regions were significantly decreased in patients group compared with the normal group. For the deep retinal layer, the vascular density of MIR, SR, S, C1, C2 regions also reduced in patient group. The ROC analysis demonstrated that OCTA possesses significant diagnostic performance for pancreatitis. In conclusion, patients with pancreatitis may have retinal microvascular dysfunction, and OCTA can be a valuable tool for detecting alterations in ocular microcirculation in pancreatitis patients in clinical practice., (© 2024.

- Abstract
The increasing incidence of cardiovascular disease (CVD) is a significant global health concern, affecting millions of individuals each year. Accurate diagnosis of acute CVD poses a formidable challenge, as misdiagnosis can significantly decrease patient survival rates. Traditional biomarkers have played a vital role in the diagnosis and prognosis of CVDs, but they can be influenced by various factors, such as age, sex, and renal function. Soluble ST2 (sST2) is a novel biomarker that is closely associated with different CVDs. Its low reference change value makes it suitable for continuous measurement, unaffected by age, kidney function, and other confounding factors, facilitating risk stratification of CVDs. Furthermore, the combination of sST2 with other biomarkers can enhance diagnostic accuracy and prognostic value. This review aims to provide a comprehensive overview of sST2, focusing on its diagnostic and prognostic value as a myocardial marker for different types of CVDs and discussing the current limitations of sST2., (© 2024.

- Abstract
Background: The examination of anti-double stranded DNA (ds-DNA) IgG antibody is of great significance for the diagnosis, differential diagnosis, assessment of disease activity, and prognosis of disease recurrence in SLE., Methods: We used a chemiluminescence method to detect ds-DNA IgG and found that the levels of ds-DNA IgG antibody in the patient's serum were significantly increased and the indirect immunofluorescence (IIF) test result was negative. Laboratory tests show that the patient's RF level far exceeds the upper limit of their reference range., Results: RF 110.6 IU/mL, ds-DNA IgG 753 IU/mL; After PEG6000 treatment, the RF was 108.7 IU/mL, and then the ds-DNA IgG was measured at 23.5 IU/mL., Conclusions: The RF IgM subtype is the main cause of RF interference in IgG antibody detection, mainly due to the binding of the Fc region of RF to the Fab segment of IgG. Combining with capture antibodies and labeled antibodies leads to the formation of non-specific detection signals, or directly reacting with the detected substance, resulting in false positive test results.

- Abstract
Background: Heterophilic antibodies (HA) are one of the main substances that interfere with immunology, especially chemiluminescence immunoassay. Non-specific binding, labeling antibodies, bridging to capture antibodies, or labeling antigens can interfere with the detection process, leading to serious discrepancies between the measured results and clinical manifestations, and even delaying clinical diagnosis and treatment., Methods: This paper is a case of epidemic hemorrhagic fever causing pseudo CEA elevation caused by heterophagy induced antibodies in the body., Results: The patient's CEA detected on the ABBOTT detection platform was 51.1 ng/mL, and on the ROCHE detection platforms it was 4.66 ng/mL, and treated by PEG precipitation it was 45.2 ng/mL, after diluting the sample the CEA was 50.2 ng/mL, meanwhile the patient's platelets were 96 x 109/L and serum creatinine was 188.4 μmol/L, epidemic hemorrhagic fever IgM antibody was positive., Conclusions: When the test results do not match clinical symptoms, further confirmation is required through additional testing. Patients who use mouse monoclonal antibody preparations for diagnosis or treatment may have human anti-mouse antibodies in their serum, and the test results may falsely increase or decrease.

- Abstract
HD-Zip (Homeodomain-Leucine Zipper) is a family of transcription factors unique to higher plants and plays a vital role in plant growth and development. Increasing research results show that HD-Zip transcription factors are widely involved in many life processes in plants. However, the HD-Zip transcription factor for cannabis, a valuable crop, has not yet been identified. The sequence characteristics, chromosome localization, system evolution, conservative motif, gene structure, and gene expression of the HD-Zip transcription factor in the cannabis genome were systematically studied. Real-time quantitative polymerase chain reaction (qRT-PCR) was used to verify its function. The results showed that cannabis contained 33 HD-Zip gene members. The number of amino acids is 136-849aa, the isoelectric point is 4.54-9.04, and the molecular weight is 23264.32-93147.87Da. Many cis -acting elements are corresponding to hormone and abiotic stress in the HD-Zip family promoter area of cannabis. Sequencing of the transcriptome at 5 tissue sites of hemp, stems, leaves, bracts, and seeds showed similar levels of expression of 33 members of the HD-Zip gene family at 5 tissue sites. Bioinformatics results show that HD-Zip expression is tissue-specific and may be influenced by hormones and environmental factors. This lays a foundation for further research on the gene function of HD-Zip ., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

- Abstract
Myocardial infarction is defined as a sudden decrease or interruption in blood flow to the coronary arteries, causing ischemic necrosis of the corresponding cardiomyocytes. It is unclear whether systemic macrovascular alterations are associated with retinal microvascular changes. This study utilized optical coherence tomography angiography (OCTA) to compare variations in conjunctival vascular density and fundus retinal vessel density between patients with myocardial infarction (MI) and healthy controls. This study recruited 16 patients (32 eyes) with MI and 16 healthy controls (32 eyes). The superficial retinal layer (SRL), deep retinal layer (DRL) and conjunctival capillary plexus in each eye were evaluated by OCTA. Parameters measured included the density of the temporal conjunctival capillary, retinal microvascular (MIR) and macrovascular (MAR) alterations and total MIR (TMI). The microvascular density of each retinal region was evaluated by the hemisphere segmentation (SR, SL, IL, and IR), annular partition (C1, C2, C3, C4, C5 and C6), and modified early treatment of diabetic retinopathy study (R, S, L, and I) methods. In the macular area, the superficial and deep retinal microvascular densities displayed notable variations. In the superficial layers, the superficial TMI, superficial MIR, and superficial MAR, as well as densities in the SL, IL, S, L, C1, C2, C5 and C6 regions, were significantly lower in MI patients (p < 0.05 each). In the deep layers, the deep MIR and deep TMI), as well as densities in the SL, IL, L, C1, C2 and C6 regions were significantly lower in MI patients (p < 0.05 each). In contrast, the conjunctival microvascular density was significantly higher in MI patients than in healthy controls (p < 0.001). The microvascular densities measured in the deep and superficial retinal layers and in the conjunctiva differ in MI patients and healthy controls. OCTA is effective in detecting changes in the ocular microcirculation., (© 2024. The Author(s).)

- Abstract
Twenty-one new coumarin Mannich base derivatives (11a-u) were synthesized, which exhibited antiproliferation activities in HepG2 (liver cancer), A549 (lung cancer), MCF-7 (breast cancer), and HT-29 (colon cancer). Most of the target compounds showed the most potent activity against HepG2 cells compared with other cancer cells, compound 11g showed the strongest antiproliferative activity (2.10 μM) against HepG2, even superior to the positive control drug 5-FU(5.49 μM). The nitric oxide (NO) release of all compounds in HepG2 cells was determined, of which compound 11g showed high levels of NO release (10.8 μM). Notably, the solubility of compound 11g increased 13-fold compared with the lead 8. The preliminary cytotoxicity studies suggest that 11g had little effect on LO2 cells(normal liver cells, >50 μM). The effect of compound 11g on the apoptosis of HepG2 cells was also studied, and the results showed that the induction effect of compound 11g on apoptosis is a concentration-dependent manner. Our results indicate that compound 11g might be a promising lead for further studies., (© 2023 John Wiley & Sons A/S.)

- Abstract
Objective: This study aimed to investigate the effects of the peroxisome proliferator-activated receptor δ (PPARδ) agonist GW501516 on the proliferation of pulmonary artery smooth muscle cells (PASMCs) induced by hypoxia, in order to search for new drugs for the treatment and prevention of pulmonary vascular remodeling., Methods: PASMCs were incubated with different concentrations of GW501516 (10, 30, 100 nmol/L) under the hypoxic condition. The proliferation was determined by a CCK-8 assay. The cell cycle progression was analyzed by flow cytometry. The expression of PPARδ, S phase kinase-associated protein 2 (Skp2), and cell cycle-dependent kinase inhibitor p27 was detected by Western blotting. Then PASMCs were treated with 100 nmol/ L GW501516, 100 nmol/L mammalian target of rapamycin (mTOR) inhibitor rapamycin and/or 2 µmol/L mTOR activator MHY1485 to explore the molecular mechanisms by which GW501516 reduces the proliferation of PASMCs., Results: The presented data demonstrated that hypoxia reduced the expression of PPARδ in an oxygen concentration- and time-dependent manner, and GW501516 decreased the proliferation of PASMCs induced by hypoxia by blocking the progression through the G0/G1 to S phase of the cell cycle. In accordance with these findings, GW501516 downregulated Skp2 and upregulated p27 in hypoxia-exposed PASMCs. Further experiments showed that rapamycin had similar effects as GW501516 in inhibiting cell proliferation, arresting the cell cycle, regulating the expression of Skp2 and p27, and inactivating mTOR in hypoxia-exposed PASMCs. Moreover, MHY1485 reversed all the beneficial effects of GW501516 on hypoxia-stimulated PASMCs., Conclusion: GW501516 inhibited the proliferation of PASMCs induced by hypoxia through blocking the mTOR/Skp2/p27 signaling pathway., (© 2023.

- Abstract
Background: Most arthropods are famous for their large reproductive capacity, with the ovary playing a vital role in the process. The study of the regulatory mechanisms of ovarian development may have the potential for a reproduction-based pest management strategy. GATA-binding transcription factors (GATAs) as important regulatory factors mediate many physiological processes, including development, immunity, insecticide resistance and reproduction. The Pannier (pnr), a member of GATA family, was confirmed to be involved in ovarian development of Bactrocera dorsalis in our previous study. However, the direct evidence of pnr regulating the fly ovarian development is still lacking., Results: We used CRISPR/Cas9 to create Bdpnr loss-of-function mutations. Homozygous Bdpnr
-/- mutants were nonviable, with most individuals dying during embryogenesis, some surviving to the larval stages, and the remaining few dying during pupation. In contrast, heterozygous individuals reached the adult stage, but ovarian development was disrupted, with concomitant decreases in egg laying and hatching rates. We also found that two genes encoding vitellogenin proteins (BdVg1 and BdVg2) and the vitellogenin receptor (BdVgR) were significantly down-regulated in heterozygous mutants compared to wild-type controls., Conclusion: These results indicate that Bdpnr is required for embryonic and post-embryonic development, including the formation of ovaries. Bdpnr could therefore be considered as a molecular target for tephritid fly pest control. © 2022 Society of Chemical Industry., (© 2022 Society of Chemical Industry.)- Published

The correlation between genotypes, alleles and G6PD activity levels was analyzed using statistical methods, and the haplotype frequencies at the two loci was analyzed using online SHEsis software., Results: The frequencies of CC genotype ( P =0.001, OR =2.684) and C allele ( P =0.002, OR =1.681) of c.1365-13T>C in patients with G6PD deficiency were significant lower than those in the controls, the frequency of dominant model TT+TC vs CC( P =0.001, OR =2.694) in the G6PD deficiency group was higher than that in the control group, and the differences were statistically significant. The differences of genotype and allele frequencies in c.406C>T between G6PD deficiency patients and controls had no statistical significance (all P>0.05). Haplotype analysis showed that there were significant correlations between C-C, T-C haplotypes and G6PD expression levels. In G6PD deficiency group, patients with c.1365-13T>C TC genotype had higher levels of G6PD activity, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) compared with patients with TT genogype, but the values of red cell distribution width-coefficient of variation (RDW-CV) was lower than those in TT genotype patients, and the differences were statistically significant ( P <0.05). While patients with c.1365-13T>C CC genotype had lower levels of G6PD activity compared with patients with TT genogype, but the values of MCV and MCH were higher than those in TT genotype patients ( P <0.05). The average values of hematocrit(HCT), MCV, MCH and red blood cell distribution width-standard deviation (RDW-SD) in patients with c. 406C> T TT genotype were significantly higher than those in patients with c. 406C> T CC genotype.(all P <0.05)., Conclusion: The association between G6PD c.1365-13T>C and the activity levels of G6PD is statistically significant, which is worth further study.

- Abstract
Objective: To develop and validate a deep learning model based on fundus photos for the identification of coronary heart disease (CHD) and associated risk factors. Methods: Subjects aged>18 years with complete clinical examination data from 149 hospitals and medical examination centers in China were included in this retrospective study. Two radiologists, who were not aware of the study design, independently evaluated the coronary angiography images of each subject to make CHD diagnosis. A deep learning model using convolutional neural networks (CNN) was used to label the fundus images according to the presence or absence of CHD, and the model was proportionally divided into training and test sets for model training. The prediction performance of the model was evaluated in the test set using monocular and binocular fundus images respectively. Prediction efficacy of the algorithm for cardiovascular risk factors (e.g., age, systolic blood pressure, gender) and coronary events were evaluated by regression analysis using the area under the receiver operating characteristic curve ( AUC ) and R
2 correlation coefficient. Results: The study retrospectively collected 51 765 fundus images from 25 222 subjects, including 10 255 patients with CHD, and there were 14 419 male subjects in this cohort. Of these, 46 603 fundus images from 22 701 subjects were included in the training set and 5 162 fundus images from 2 521 subjects were included in the test set. In the test set, the deep learning model could accurately predict patients' age with an R2 value of 0.931 (95% CI 0.929-0.933) for monocular photos and 0.938 (95% CI 0.936-0.940) for binocular photos. The AUC values for sex identification from single eye and binocular retinal fundus images were 0.983 (95% CI 0.982-0.984) and 0.988 (95% CI 0.987-0.989), respectively. The AUC value of the model was 0.876 (95% CI 0.874-0.877) with either monocular fundus photographs and AUC value was 0.885 (95% CI 0.884-0.888) with binocular fundus photographs to predict CHD, the sensitivity of the model was 0.894 and specificity was 0.755 with accuracy of 0.714 using binocular fundus photographs for the prediction of CHD. Conclusion: The deep learning model based on fundus photographs performs well in identifying coronary heart disease and assessing related risk factors such as age and sex.- Published

- Abstract
In this paper, a novel ion-imprinted electrochemical sensor modified with magnetic nanomaterial Fe
3 O4 @SiO2 was established for the high sensitivity and selectivity determination of UO2 2+ in the environment. Density functional theory (DFT) was employed to investigate the interaction between templates and binding ligands to screen out suitable functional binding ligand for the reasonable design of the ion imprinted sensors. The MIIP/MCPE (magnetic ion imprinted membrane/magnetic carbon paste electrode) modified with Fe3 O4 @SiO2 exhibited a strong response current and high sensitivity toward uranyl ion comparison with the bare carbon paste electrodes. Meanwhile, the MCPE was fabricated simultaneously under the action of strong magnetic adsorption, and the ion imprinted membrane can be adsorbed stably on the electrode surface, handling the problem that the imprinted membrane was easy to fall off during the process of experimental determination and elution. Based on the uranyl ion imprinting network, differential pulse voltammetry (DPV) was adopted for the detection technology to realize the electrochemical reduction of uranyl ions, which improved the selectivity of the sensor. Thereafter, uranyl ions were detected in the linear concentration range of 1.0 × 10-9 mol L-1 to 2.0 × 10-7 mol L-1 , with the detection and quantification limit of 1.08 × 10-9 and 3.23 × 10-10 mol L-1 , respectively. In addition, the sensor was successfully demonstrated for the determination of uranyl ions in uranium tailings soil samples and water samples with a recovery of 95% to 104%.- Published

- Abstract
Background: Diabetes and impaired glucose regulation are very common in patients with coronary artery disease (CAD). In this study, we aim to investigate the prevalence of abnormal glucose regulation in men and women in Chinese CAD patients., Methods: In this retrospective study, 4100 patients (male, n = 2873; female, n = 1227)with CAD were enrolled. The mean age of these patients was 63 years. The demographic data, medical history, echocardiography findings and blood investigations were collected and analyzed., Results: In this population, 953 (24%) patients had definite diagnosis of type 2 diabetes mellitus, including 636 males (23%) and 317 females (27%). There was a higher prevalence of diabetes in females than men (p < 0.05). For the remaining patients, 48% (n = 959) undergone an oral glucose tolerance test (OGTT), which revealed that 83 male patients (12%) and 41 female patients (16%) suffered from the type 2 diabetes (p > 0.05). 283 men (40%) and 105 women (41%) had impaired glucose regulation (IGR) (p > 0.05). Only 338 men (25%) and 109 women (19%) showed the normal glucose regulation, implying a higher prevalence of abnormal glucose regulation in females (p < 0.01). The odd ratio (OR) showed that women were more prone to have diabetes mellitus or IGT than men and the OR was 1.44 and 1.43 respectively., Conclusion: Abnormal glucose regulation is highly prevalent in CAD patients. The women are more prone to have diabetes mellitus or IGT than men., (© 2022. The Author(s).)

- Abstract
Objective: To investigate the effects of the peroxisome proliferator-activated receptor δ (PPARδ) agonist GW501516 on the proliferation of primary rat proliferation of pulmonary artery smooth muscle cells ( PASMCs ) induced by hypoxia, in order to discover new drugs for the treatment and prevention of pulmonary vascular remodeling. Methods: The PASMCs in the control group were cultured with 21% oxygen, while the PASMCs in the hypoxia group were cultured with 3% oxygen to induce cell proliferation. PASMCs were incubated with GW501516 at the concentrations of 10, 30 and 100 nmol/L under hypoxic conditions for different time points (12, 24, and 48 h) to find out the appropriate concentrations of GW501516 for inhibition the proliferation. PASMCs were incubated with 100 nmol/L GW501516 and ( or ) protein kinase B (AKT) agonist SC79 for 24 h to explore related mechanisms of GW501516 in regulating the proliferation. The proliferation and DNA synthesis were determined by CCK-8 and BrdU kit. The cell cycle progression was analyzed by flow cytometry. The mRNA expressions of Cyclin D1 and the cyclin kinase inhibitor p27(p27) were measured by quantitative real-time PCR (RT-PCR). The expressions of PPARδ, total and phosphorylated forms AKT and glycogen synthase kinase 3β (GSK3β) were detected by Western blot. Results: Compared with the hypoxia group, PASMCs incubated with different concentrations of GW501516 (10, 30, 100 nmol/L) for 12, 24, 48 h under hypoxic conditions could inhibit the proliferation and DNA synthesis, and the greatest level of suppression of proliferation was induced by GW501516 at the concentration of 100 nmol/L( P <0.05 or P <0.01). Compared with the control group, the expression of PPARδ was upregulated markedly in PASMCs incubated with 100 nmol/L GW501516 for 24 h,while hypoxia could downregulate the expression of PPARδ significantly( P <0.01). Compared with the hypoxia group, 100 nmol/L GW501516 blocked the proliferation and DNA synthesis of PASMCs significantly( P <0.01), increased the proportion of PASMCs in G0 /G1 phase while decreased the proportion of PASMCs in S phase and G2 /M phase( P <0.05 or P <0.01), markedly downregulated the mRNA expression of cyclin D1 and upregulated the mRNA expression of p27( P <0.01), significantly inhibited the protein expressions of phosphorylated AKT and GSK3β( P <0.01). Compared with the 100 nmol/L GW501516 hypoxia group, AKT agonist SC79 reversed all the above effects of 100 nmol/L GW501516 on hypoxia stimulated PASMCs( P <0.05 or P <0.01). Conclusion: GW501516 inhibits hypoxia induced proliferation in PASMCs via inactivating AKT/GSK3β signaling pathway.

- Abstract
Background: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease., Objective: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium., Design, Setting, Participants and Intervention: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m
2 , and 24-hour proteinuria level of 0.5-3.0 g, were recruited in 41 hospitals across 19 provinces in China and were randomly divided into five groups: SYKFT, losartan potassium 50 mg or 100 mg, SYKFT plus losartan potassium 50 mg or 100 mg., Main Outcome Measures: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment., Results: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group., Conclusion: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone., Trial Registration Number: NCT02063100 on ClinicalTrials.gov., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2021 Shanghai Changhai Hospital.

- Abstract
Accurate spatial distribution information of soil properties would be helpful for improving the accuracy of soil organic carbon storage estimation. In this study, terrain factors were used as predictors, and the fuzzy C-means (FCM) clustering method was used to make digital soil prediction mapping for soil organic carbon content, soil bulk density, soil depth, and soil gravel content in Nanshan forest farm in Jiyuan City of Henan Province. Based on the digital mapping results, the prediction mapping of soil organic carbon density and the estimation of soil organic carbon storage were realized. The results showed that the average soil organic carbon density in the study area based on the digital soil mapping method was 4.24 kg·m
-2 , the mean error (ME), mean absolute error (MAE) and root mean square error (RMSE) of the prediction map were 0.08, 2.80 and 5.03 kg·m-2 , respectively. The accuracy, stability and reliability of the prediction results were higher than the tradiation methods. The soil organic carbon storage in the study area was estimated to be 3.08×108 kg. Based on the digital soil mapping technology, only a small number of soil samples could be used to map and estimate the soil organic carbon density with high accuracy, which could characterize the spatial distribution characteristics of soil organic carbon density. This study provided a new way to estimate soil organic carbon storage, which would help to improve the accuracy and efficiency of soil organic carbon storage estimation.- Published

- Abstract
Background: A number of studies have reported the association between dietary patterns and the risk of chronic kidney disease (CKD), however a consistent perspective hasn't been established to date. Herein, we conducted this systematic review and meta-analysis of observational studies to assess the association between dietary patterns and CKD., Methods: MEDLINE, EBSCO and references from eligible studies were searched for relevant articles published up to 9 May 2020 that examined the association of common dietary patterns and CKD. The heterogeneity among studies was assessed by Cochran's Q test and I
2 methods., Results: Seventeen eligible studies, involving 149,958 participants, were included in our systematic review and meta-analysis. The highest compared with the lowest category of healthy dietary pattern was significantly associated with a lower risk of CKD (OR=0.69; CI: 0.57, 0.84; P=0.0001). A higher risk of CKD was shown for the highest compared with the lowest categories of Western-type dietary pattern (OR=1.86; CI: 1.21, 2.86; P=0.005). There were evidence of a lower risk of CKD in the highest compared with the lowest categories of light-moderate drinking pattern (OR=0.76; CI: 0.71, 0.81; P< 0.0001) and heavy drinking pattern (OR=0.67; CI: 0.56, 0.80; P< 0.0001)., Conclusions: The results of this systematic review and meta-analysis show that a healthy dietary pattern and alcohol drinking were associated with lower risk of CKD, whereas a Western-type dietary pattern was associated with higher risk of CKD.- Published

- Abstract
Objective: To describe a novel procedure of radical vulvectomy and inguinal lymphadenectomy using a single incision (RVIL-SI) for the treatment of vulvar malignancy. Methods: In March, 2019, two cases affected with vulvar cancer (the first one is stage ⅢA squamous cell carcinoma and the second one is stage ⅠB with malignant melanoma) underwent this novel procedure, which was characterized by the combination of radical vulvectomy and bilateral inguinal lymphadenectomy without making additional incisions in groin areas. The boundaries of femoral triangle could be exposed perfectly using the initial incision of radical vulvectomy and the combined superficial and deep groin lymph node dissection were done subcutaneously from medial to lateral. Preoperative data and short term follow-up outcomes were collected. Results: The RVIL-SI was successfully conducted in two patients without any incisions of groin. The great saphenous veins were all spared. The operative time, average blood loss and median total regional lymph nodes of two cases were close. No major intraoperative complications occurred. Micrometastasis in one right superficial inguinal node was found in the first case with ipsilateral huge cancer lesion. No drain tube was left in inguinal areas intraoperatively. On postoperative day 3, the second case suffered mild lymphocele of right groin, which was resolved via repeated percutaneous needle puncture followed by elastic compression. Postoperative hospital stay of two cases were 10 and 11 days, respectively. With no skin complication at the time of writing this report. Conclusion: Our preliminary experience with the RVIL-SI has confirmed the reproducibility and minimal invasive therapeutic potential in the treatment for patients with vulvar cancer. But this novel procedure is in its infancy stage. Although short-term results are encouraging, a larger series with longer follow-up are required to fully evaluate the therapeutic efficacy.

- Abstract
Cyanobacterial blooms (CBs) in eutrophic lakes can cause various harmful issues to both humans and animals, disturb drinking water supply, and devastate lake ecosystems. Although great progresses have been made in many lakes from China and abroad on CBs prevention, mitigation and control, systematic research on the influencing factors of CBs in hypereutrophic plateau Lake Dianchi over a long time span is so far unavailable. This study comprehensively generalized both meteorological and water quality changes in Lake Dianchi during 1990-2015 on both yearly and monthly basis, separated Caohai from Waihai of Lake Dianchi regarding water quality variations, and investigated the individual and joint influencing meteorological and water quality factors on CBs using Spearman correlation, principal component analysis, and multivariate linear stepwise regression. Four specific lake regions, i.e. Caohai, northern Waihai, central Waihai, and southern Waihai, were respectively analyzed due to significant water quality heterogeneity. Results indicated that mild temperatures, low wind velocities, and hypereutrophic water conditions all favor CBs in Lake Dianchi, and the significant temperature rising trend may exacerbate severer CBs in the future. Despite configuration differences, the first principal components on CBs in the four sub-regions of Lake Dianchi were all consisted of meteorological factors, while water quality parameters especially total phosphorus concentrations contributed to the second principal component. Quantification of joint meteorological and water quality influencing factors on CBs needs further improvement, and largely relies on the accuracy of future weather forecasts, in order to set the goal of water quality improvement in each specific lake region for effective CBs management., (Copyright © 2019 Elsevier B.V.

- Abstract
Herein, Au core Pd shell Pt cluster nanorods (Au@Pd@Pt NRs) with enhanced catalytic activity were rationally designed for carbon dioxide (CO
2 ) reduction. The surface composition and Pd-Pt ratios significantly influenced the catalytic activity, and the optimized structure had only a half-monolayer equivalent of Pt ( θPt = 0.5) with 2 monolayers of Pd, which could enhance the catalytic activity for CO2 reduction by 6 fold as compared to the Pt surface at -1.5 V vs. SCE. A further increase in the loading of Pt actually reduced the catalytic activity; this inferred that a synergistic effect existed among the three different nanostructure components. Furthermore, these Au NRs could be employed to improve the photoelectrocatalytic activity by 30% at -1.5 V due to the surface plasmon resonance. An in situ SERS investigation inferred that the Au@Pd@Pt NRs ( θPt = 0.5) were less likely to be poisoned by CO because of the Pd-Pt bimetal edge sites; due to this reason, the proposed structure exhibited highest catalytic activity. These results play an important role in the mechanistic studies of CO2 reduction and offer a new way to design new materials for the conversion of CO2 to liquid fuels., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)- Published

- Abstract
Objective: To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction., Methods: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period., Results: After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min
-1 •1.73 m-2 , respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min-1 •1.73 m-2 , respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min-1 •1.73 m-2 per year., Conclusion: Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).- Published

- Abstract
We report on a novel kind of accelerating beams that follow parabolic paths in free space. In fact, this accelerating peculiar polygon beam (APPB) is induced by the spectral phase symmetrization of the regular polygon beam (RPB) with five intensity beam (RPB) with five intensity peaks, and it preserves a peculiar symmetric structure during propagation. Specially, such beam not only exhibits autofocusing property, but also possesses two types of accelerating intensity maxima, i.e., the cusp and spot-point structure, which does not exist in the previously reported accelerating beams. We also provide a detailed insight into the theoretical origin and characteristics of this spatially accelerating beam through catastrophe theory. Moreover, an experimental scheme based on a digital micromirror device (DMD) with the binary spectral hologram is proposed to generate the target beam by precise modulation, and a longitudinal needle-like focus is observed around the focal region. The experimental results confirm the peculiar features presented in the theoretical findings. Further, the APPB is verified to exhibit self-healing property during propagation with either obstructed cusp or spot intensity maxima point reconstructing after a certain distance. Hence, we believe that the APPB will facilitate the applications in the areas of particle manipulation, material processing and optofludics.

- Abstract
Objective: To investigate the impact of conservative laparoscopic surgery for endometriosis with postoperative gonadotropin-releasing hormone agonist (GnRHa) therapy on the pregnancy outcomes in patients with endometriosis-associated infertility., Methods: The clinical data were collected from the patients with endometriosis-associated infertility undergoing conservative laparoscopic surgery in our department between January, 2011 and December, 2016. The patients were divided into laparoscopic surgery only group (without any other treatments) and postoperative GnRha therapy group, and the pregnancy outcomes were compared between the two groups at different time points during the follow-up., Results: In cases with moderate or severe endometriosis, laparoscopic surgery with postoperative GnRha therapy was associated with a significantly higher clinical pregnancy rate than laparoscopic surgery alone (P<0.05). In patients receiving postoperative GnRha therapy, the accumulative pregnancy rates at 6, 12, 24 and 36 months after discontinuation of GnRha therapy were significantly higher than those in patients receiving laparoscopic surgery alone. The pregnancy rate following IVF-ET cycles was significantly higher than the spontaneous pregnancy rate in patients receiving conservative laparoscopic surgery alone (P<0.05), while such a difference was not found in patients with postoperative GnRHa therapy (P>0.05)., Conclusions: GnRHa therapy after conservative laparoscopic surgery can significantly increase the clinical pregnancy rate in infertile 6 months women with moderate or severe endometriosis but not in mild cases. Within 6 months following laparoscopic surgery or following discontinuation of GnRHa therapy is the optimal time window for pregnancy, and a longer time from therapy discontinuation is associated with a lower possibility of spontaneous pregnancy.

- Abstract
Objective: To explore the therapeutic effect of Yishen Qufeng Shengshi Recipe (, YQSR) in patients with glomerular proteinuria METHODS: A total of 145 patients with glomerular proteinuria were selected and randomly assigned to the treatment group (108 cases) and the control group (37 cases) according to a random number table in a ratio of 3:1. All patients received conventional and symptomatic treatment. In addition, patients in the treatment and control groups were given YQSR (200 mL, twice per day, orally) and losartan (50 mg/d orally), respectively for 6 months. The 24-h urine protein quantity, blood urea nitrogen, and serum creatinine in the two groups were measured at multiple time points before and after treatment., Results: At the end of the study, 5 cases were lost to follow-up in the treatment group and 1 in the control group. Finally, the statistical data included 103 cases in the treatment group and 36 cases in the control group. The total effectiveness after 2, 4, and 6 months was 81.6% (84/103), 87.4% (90/103), and 92.2% (95/103), respectively, in the treatment group and 47.2% (17/36), 55.6% (20/36), and 61.1% (22/36), respectively, in the control group, with significant difference between the two groups (P<0.01 at all observation points). In the treatment group, the curative effect after 6 months was better than that after 2 months (P<0.05). The 24-h urine protein quantity was significantly lower in the treatment group at 3, 4, 5, and 6 months than that in the control group (P<0.05 or P<0.01, respectively) CONCLUSION: YQSR could significantly reduce the amount of glomerular proteinuria in the early stage.

- Abstract
Berberine (BBR) has previously been found to exert beneficial effects on renal injury in experimental rats. However, the mechanisms underlying these effects are not yet fully understood. Tumor necrosis factor (TNF) receptor-associated factor 5 (TRAF5) has been demonstrated to mediate the activation of nuclear factor-κB (NF-κB), which has been implicated in the pathogenesis of chronic kidney disease (CKD). The aim of this study was to investigate the effects of BBR on kidney injury and the activation of the NF-κB signaling pathway in mouse podocytes. TRAF5 was found to be overexpressed in patients with CKD and chronic renal failure (CRF) (data obtained from the dataset GSE48944, as well as from patients at Shuguang Hospital). TRAF5 overexpression significantly inhibited cell viability and induced the apoptosis of mouse podocytes. However, BBR prevented the decrease in cell viability and the apoptosis induced by TRAF5 overexpression. The NF-κB inhibitor, caffeic acid phenethyl ester (CAPE), mimicked the protective effects of BBR, as evidenced by the increased expression of nephrin and podocin, and the decreased the expression of caspase-3 and the ratio of Bax/Bcl-2. Moreover, BBR prevented the decrease in cell viability decrease and the apoptosis induced by TNF-α, interleukin (IL)-6 and lipopolysaccharide (LPS). Taken together, our data indicate that BBR exerts protective effects against CRF partly through the TRAF5-mediated activation of the NF-κB signaling pathway in mouse podocytes.

- Abstract
Purpose: To investigate the role and the underlying mechanism of scaffold attachment factor B ( SAFB ) in the progression of colorectal cancer (CRC). Experimental Design: SAFB expression was analyzed in the Cancer Outlier Profile Analysis of Oncomine and in 175 paraffin-embedded archived CRC tissues. Gene Ontology analyses were performed to explore the mechanism of SAFB in CRC progression. Western blot, RT-PCR, luciferase assay, and chromatin immunoprecipitation (ChIP) were used to detect the regulation of transforming growth factor-β-activated kinase 1 ( TAK1 ) and NF-κB signaling by SAFB The role of SAFB in invasion, metastasis, and angiogenesis was investigated using in vitro and in vivo assays. The relationship between SAFB and TAK1 was analyzed in CRC tissues. Results: SAFB was downregulated in CRC tissues, and low expression of SAFB was significantly associated with an aggressive phenotype and poorer survival of CRC patients. The downregulation of SAFB activated NF-κB signaling by targeting the TAK1 promoter. Ectopic expression of SAFB inhibited the development of aggressive features and metastasis of CRC cells both in vitro and in vivo The overexpression of TAK1 could rescue the aggressive features in SAFB-overexpressed cells. Furthermore, the expression of SAFB in CRC tissues was negatively correlated with the expression of TAK1- and NF-κB-related genes. Conclusions: Our results show that SAFB regulated the activity of NF-κB signaling in CRC by targeting TAK1 This novel mechanism provides a comprehensive understanding of both SAFB and the NF-κB signaling pathway in the progression of CRC and indicates that the SAFB-TAK1-NF-κB axis is a potential target for early therapeutic intervention in CRC progression.

- Abstract
Background: Chronic kidney disease (CKD) with moderate-to-severe renal dysfunction usually exhibits an irreversible course, and available treatments for delaying the progression to end-stage renal disease are limited. This study aimed to assess the efficacy and safety of the traditional Chinese medicine, Niaoduqing particles, for delaying renal dysfunction in patients with stage 3b-4 CKD., Methods: The present study was a prospective, randomized, double-blind, placebo-controlled, multicenter clinical trial. From May 2013 to December 2013, 300 CKD patients with an estimated glomerular filtration rate (eGFR) between 20 and 45 ml·min-1·1.73 m-2, aged 18-70 years were recruited from 22 hospitals in 11 Chinese provinces. Patients were randomized in a 1:1 ratio to either a test group, which was administered Niaoduqing particles 5 g thrice daily and 10 g before bedtime for 24 weeks, or a control group, which was administered a placebo using the same methods. The primary endpoints were changes in baseline serum creatinine (Scr) and eGFR after completion of treatment. The primary endpoints were analyzed using Student's t-test or Wilcoxon's rank-sum test. The present study reported results based on an intention-to-treat (ITT) analysis., Results: A total of 292 participants underwent the ITT analysis. At 24 weeks, the median (interquartile range) change in Scr was 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the test and control groups, respectively (Z = 2.642, P = 0.008), and the median change in eGFR was -0.2 (-4.3-2.7) and -2.2 (-5.7-0.8) ml·min-1·1.73 m-2, respectively (Z = -2.408, P = 0.016). There were no significant differences in adverse events between the groups., Conclusions: Niaoduqing particles safely and effectively delayed CKD progression in patients with stage 3b-4 CKD. This traditional Chinese medicine may be a promising alternative medication for patients with moderate-to-severe renal dysfunction., Trial Registration: Chinese Clinical Trial Register, ChiCTR-TRC-12002448; http://www.chictr.org.cn/showproj.aspx?proj=7102.

- Abstract
Aim: To investigate whether hepatitis viral DNA load at 24 wk of treatment predicts response at 96 wk in patients with chronic hepatitis B., Methods: A total of 172 hepatitis B envelope antigen (HBeAg)-positive chronic hepatitis B patients who received initial treatment at 16 tertiary hospitals in Hunan Province, China were enrolled in this study. All patients received conventional doses of lamivudine and adefovir dipivoxil, telbivudine, entecavir dispersible tablets, or entecavir tablets for 96 wk. Patients who used other antiviral drugs or antitumor and immune regulation therapy were excluded. Patients were stratified into three groups according to their viral DNA load at 24 wk: < 10 IU/mL (group 1), 10-10
3 IU/mL (group 2), and > 103 IU/mL (group 3). Correlations of 24-wk DNA load with HBeAg negative status and HBeAg seroconversion at 96 wk were analyzed. Receiver operating characteristic curve analysis was used to test the predictive value of the HBV DNA load at 24 wk for long-term response., Results: The rates of conversion to HBeAg negative status and HBeAg seroconversion rates were 53.7% and 51.9%, respectively, in group 1; 35.21% and 32.39% in group 2; and 6.38% and 6.38% in group 3. The receiver operating characteristic curves for the three subgroups revealed that the lowest DNA load (< 10 IU/mL) was better correlated with response at 96 wk than a higher DNA load (10-103 IU/mL). Nested PCR was used for amplifying and sequencing viral DNA in patients with a viral DNA load > 200 IU/mL at 96 wk; resistance mutations involving different loci were present in 26 patients, and three of these patients had a viral DNA load 10-103 IU/mL at 96 wk., Conclusion: Hepatitis B viral DNA load at 24 wk of antiviral treatment in patients with chronic hepatitis B is a predictor of the viral load and response rate at 96 wk., Competing Interests: Conflict-of-interest statement: The authors declare no conflict of interest.- Published

- Abstract
Objectives: To determine the underlying mechanism of Gubentongluo Formula in the treatment of IgA nephropathy (IgAN)., Methods: C57BL/6 mice were randomly divided into four groups: normal group ( n =10), IgAN group ( n =10), control group ( n =10) and treatment group ( n =10). Mice in the normal and IgAN groups were intragastricly administered with normal saline for 12 weeks; while those in the control and treatment groups were given fenofibrate [30 mg/(kg!$d) and Gubentongluo Formula [1.67 mL/(g!$d)], respectively. Urinary albumin was detected at week 0 and 12. At week 12, protein expressions of peroxisome proliferstor activated receptor α (PPARα), liver fatty acid-binding proteins (L-FABP), 4-hydroxy-2-nonenal (4-HNE), and hemeoxygenase-1(HO-1) in renal tissues were determined by Western blot; mRNA expressions of PPARα and L-FABP in renal tissues were determined by florescent quantitative reverse transcription-polymerase chain reaction (qRT-PCR)., Results: At week 12, higher levels of urinary albumin, pathological injuries in glomerular mesangial area, and lower expressions of protein and mRNA of PPARα and L-FABP were found in mice in the IgAN group compared with those in the normal group ( P <0.01). The levels of those indicators decreased in those treated with fenofibrate and Gubentongluo Formule, but still higher than the normal controls ( P <0.01). The mice treated with Gubentongluo Formula had more significant improvement than those treated with fenofibrate ( P <0.05)., Conclusion: [CM(155.3mm]Gubentongluo formula can improve proteinuria and pathological injuries in glomerular mesangial area of IgAN mice, due to reduction of oxidative stress in renal tissues through regulating the expressions of PPARα and L-FABP.

- Abstract
Objective To observe effects of Kangxianling Recipe ( KXLR) on p38MAPK/NF- κBp65 mediated inflammatory factors in chronic renal failure ( CRF) model mice. Methods Totally 56 C57BL/6J male mice (18 -22 g) were recruited in this experiment. Ten were randomly selected as a sham-operation group. The rest 46 mice were used for preparing CRF model by 5/6 nephrectomization. To- tally 33 successfully modeled mice were divided into the model group, the rapamycin (RAP) group, and the KXLR group according to serum creatinine (SCr) level, 11 in each group. Mice in the RAP group were administered with rapamycin (0.13 mg/100 g per day, 0. 5 mL each time) by gastrogavage. Mice in the KXLR group were administered with KXLR (2 g/100 g per day, 0. 5 mL each time) by gastrogavage. Equal volume of distilled water was administered to mice in the model group and the sham-operation group. Mice were sacrificed after 8 weeks of consecutive medication. The expression of neutrophils was ob- served using immunohistochemical assay. Expression levels of p38MAPK/NF-κB p65 protein and TNF-α/ IL-6 mRNA were detected by Western blot and Real-time PCR. Results Compared with the sham-opera- tion group, the number of positive neutrophils increased, expression levels of p38MAPK/NF-κB p65 protein and TNF-α/IL-6 mRNA were enhanced significantly in the model group (P <0. 05, P <0. 01). Com- pared with the model group, the number of neutrophils was reduced, expression levels of p38MAPK/NF- κB p65 protein and TNF-α/IL-6 mRNA were decreased significantly in the KXLR group and the RAP group (P <0. 05, P <0. 01). RAP showed better effect in decreasing p38MAPK protein expression than KXLR (P <0. 05). There was no statistical difference in the rest indices between the KXLR group and the RAP group (P >0. 05). Conclusions KXLR participated the regulation of p38MAPK/NF-κB p65 mediated in- flammation factors. It had certain improvement in renal fibrosis induced renal failure.

- Abstract
The energy received through remote sensing sensors contains the amount of reflected solar energy and emitted energy of objects in middle-wave infrared (MWIR, 3~5 μm). Usually, the reflected solar energy is weak in MWIR spectrum. In some certain situations like sun glint area in sea surface, however, the energy is relatively significant and less sensitive to atmospheric effects. Meanwhile, for the satellite sensor which equipped with onboard calibration system, its onboard radiation performance of MWIR(using blackbody calibration)is quite stable. Therefore, the MWIR reflectance in sea surface glint area can be considered as a reference for cross-calibration between the solar reflected bands. Based on this idea, this paper constructed an improved non-linear split window model that is suitable for VIIRS (visible infrared imaging radiometer) MWIR band and used this model to calculate the MWIR reflectance of sun glint area in southern Indian Ocean. This model made statistics, getting the relationship between the reflectance of VIIRS M12 and M13 bands at first, and then used the non-linear split window algorithm to calculate the actual sea surface reflectance. The uncertainty of the simulation model was 0.83%. On this basis, this paper calculated sea surface reflectance of selected sample regions based on the data of VIIRS M12 band (center wavelength: 3.697 μm) in sun glint areas. And then verified the reflectance accuracy by two methods, getting the two accuracies were about 0.239% and 0.23%, respectively. It proves that the calculation model in this paper can greatly improve the accuracy compared to the situation when the sea surface reflectance is between M12 and M13 which are assumed to be equal (accuracy of 2.48% and 1.03%, respectively). It also indicated that the model is feasible and effective to calculate the reflectance in sea surface glint area with VIIRS M12 MWIR band, and the accuracy can meet the requirements of MWIR sea surface reflectance as a calibration reference among bands.

- Abstract
Photocatalysis is a promising technology for renewable energy production. Many photocatalysis have realized the visible-light-driven catalytic activity. However, it is still difficult to achieve the enhanced photocatalytic activity with tunable wavelength. We have designed tunable wavelength enhanced photoelectrochemical cells by tuning the surface plasmon resonance (SPR) peaks, which can be controlled by the aspect ratios of the Au nanorods, for both the cathode with the hydrogen evolution reaction and the anode with the electrooxidation of methanol reaction. The optimal photocatalytic activity of the hydrogen evolution and electrooxidation of the methanol can be realized only when the illuminating wavelength matches with the SPR peaks, which is quite selective to the illuminating wavelength. The blue shift of the SPR peak increases the photoelectrocatalytic effect whereas the red shift enhances the photothermal effect. Such studies provide a useful way for improving the photocatalytic activity and the selectivity of the photocatalytic reactions by adjusting the illuminating wavelength.

- Abstract
Objective To evaluate the clinical effectiveness of JianpiQinghua decoction in treating stage 3 chronic kidney disease (CKD3) with syndrome type of dampness-heat due to spleen deficiency. Methods A multicenter, randomized, controlled, prospective, double-blind, and double-simulation study was undertaken. A total of 270 CKD3 patients with syndrome type of dampness-heat due to spleen deficiency from the outpatient departments of six general hospitals were randomly divided into telmisartan+analog traditional Chinese medicine (TA) group, traditional Chinese medicine+analog telmisartan (TCMA) group, and telmisartan+traditional Chinese medicine (TTCM) group, in which the corresponding treatment was applied in addition to basic treatment. Six months later, changes in the traditional Chinese medicine (TCM) clinical symptom scores and renal functions before and after treatment were compared among these three groups. Results Of these 270 CKD3 patients who had been enrolled in this study, 30 cases lost to follow-up. The baseline data were comparable among these three groups. After treatment, the TCM clinical symptom scores of both syndrome of spleen-qi deficiency and dampness-heat in TA group were significantly higher than those in TCMA group and TTCM group (P<0.001). With the treatment time prolonged, the TCM clinical symptom scores showed similar descending trends in TCMA group and TTCM group but were different from that in TA group. After treatment, abnormal creatinine rate decreased (P=0.003), and these three treatments and their interactions with each visit had no effect on serum urea nitrogen value (P=0.270, P=0.520); with prolonged treatment, the estimated glomerular filtration rates in three groups tended to be relatively stable after the first rise. The liver function and abnormal serum potassium rate were not statistically significant before and after treatment (P>0.05). Conclusions JianpiQinghua decoction can improve clinical symptoms of TCM in CKD3 patients with syndrome type of dampness-heat due to spleen deficiency and thus improve the quality of life and prognosis. The clinical efficacy of JianpiQinghua decoction alone or combined with telmisartan is superior to telmisartan monotherapy.

- Abstract
In this study, three GDI (gasoline direct injection) and one PFI (port fuel injection) light-duty gasoline vehicles were characterized for their particle emission (number concentration and size distributions). Two condensation particle counters (CPC) with different activation efficiencies (50% cut off diameter) were used. It was found that the number concentration of particles emitted by GDI gasoline vehicle was approximately one order of magnitude higher than that from PFI gasoline vehicle. High emission of particles occurred within the first 200 s of cold start. The number concentration of particles emitted from GDI vehicle was largely influenced by the vehicle working condition, while that of PFI vehicle was relatively stable despite of varying working conditions. The size distributions of particles emitted from GDI and PFI vehicles had both nucleation mode and accumulation mode. The peak diameter of nucleation mode particles was in the range of 20-27 nm, while that of accumulation mode particle was in the range of 80-95 nm. The number concentrations measured by the UCPC (50% cut off diameter of 2.5 nm) were 35% (GDI) and 50.4% (PFI), respectively, higher than those measured by the CPC (50% cut off diameter of 23 nm) used by the regulation.

- Abstract
Objective To analyze the correlation between obesity/overweight and constitutions of Chinese medicine (CM)/cardiovascular risk factors in elderly residents of Tianhe District Wushan Com- munity, Guangzhou City. Methods Recruited were 1 054 elderly residents (over 60 years), who had free health examinations in Tianhe District Wushan Community of Guangzhou City from October 2014 to September 2015. They were assigned to the obesity group (107 cases) , the overweight group (431 ca- ses) , and the normal weight group (516 cases) according to body mass index (BMI) by randomized sampling. Constitution types of CM were assessed using Classification and Judgment of Constitution Types of CM. Health files were filled in. General indices such as waist circumference, blood pressure, etc., and blood biochemical indicators such as fasting blood glucose, blood lipids, uric acid, blood creati- nine, etc. were detected. The correlation between constitution types of CM and obesity/overweight was analyzed using multivariate Logistic regression analysis. Results Among the 1 054 elderly residents, 75. 62% (797/1 054) of those were of biased constitution and 24. 38% (257/1 054) were of normal consti- tution. Phlegm dampness (247 cases, 23. 43%), yin deficiency (150 cases, 14. 23%), and qi deficiency (136 cases, 12. 90%) constitution were top 3 commonly seen biased constitution types. Multiple Logistic regression analysis showed that the risk of obese/overweight patients of phlegm dampness constitution was 61. 641 times (Cl: 24. 491 -155. 144) and 9. 393 times (Cl: 5. 910 -14. 929) that of subjects of nor- mal constitution respectively (P <0. 01) ; the risk of obese/overweight patients of dampness heat consti- tution was 21. 478 times (Cl: 6. 978 -66. 102) and 4. 505 times ( Cl: 2. 308 -8. 793) that of subjects of normal constitution respectively (P <0. 01) ; the risk of obese/overweight patients of qi deficiency consti- tution was 3.408 times ( Cl:1. 161 -10. 004) and 1. 655 times (Cl: 1. 062 -2. 580) that of subjects of nor- mal constitution respectively (P <0. 05). Compared with normal body weight senile, the incidences of ab- dominal obesity, hypertension, diabetes were obviously higher in obese/overweight senile (P <0. 01 , P < 0. 05). Their values of fasting blood glucose, triglyceride, high-density lipoprotein, and uric acid were ob- viously higher than those in normal body weight senile (P <0. 01). Conclusions Community obese/over- weighed elderly residents have the tendency of phlegm dampness, dampness heat, and qi deficiency constitutions. Compared with the normal body weight senile, they have higher risk of cardiovascular risk factors, and increased risks of suffering from hypertension, diabetes, and dyslipidemia.

- Abstract
This was the first multicenter, cross-sectional survey to assess the prevalence of anemia, patient awareness, and treatment status in China. Data of patients with chronic kidney disease (CKD; age, 18-75 years; both out- and inpatients) from 25 hospitals in Shanghai, seeking medical treatment at the nephrology department, were collected between July 1, 2012 and August 31, 2012. The prevalence, awareness, and treatment of anemia in patients with nondialysis CKD (ND-CKD) were assessed. Anemia was defined as serum hemoglobin (Hb) levels ≤12 g/dL in women and ≤13 g/dL in men. A total of 2420 patients with ND-CKD were included. Anemia was established in 1246 (51.5%) patients: 639 (51.3%) men and 607 (48.7%) women. The prevalence of anemia increased with advancing CKD stage (χtrend = 675.14, P < 0.001). Anemia was more prevalent in patients with diabetic nephropathy (68.0%) than in patients with hypertensive renal damage (56.6%) or chronic glomerulonephritis (46.1%, both P < 0.001). Only 39.8% of the anemic patients received treatment with erythropoietin and 27.1% patients received iron products; furthermore, 22.7% of the patients started receiving treatment when their Hb level reached 7 g/dL. The target-achieving rate (Hb at 11-12 g/dL) was only 8.2%. Of the 1246 anemia patients, only 7.5% received more effective and recommended intravenous supplementation. Anemia is highly prevalent in patients with ND-CKD in China, with a low target-achieving rate and poor treatment patterns. The study highlights the need to improve multiple aspects of CKD management to delay the progression of renal failure., Competing Interests: The authors have no conflicts of interest to disclose.

- Abstract
Renal interstitial fibrosis (RIF) is a common development in chronic renal diseases that can lead to uremia and be life-threatening. The RIF pathology has complicated extracellular and intercellular mechanisms, involving many cells and cytokines, resulting in an incomplete mechanistic understanding of the disease. Finding effective herbs or herbal extracts for prevention and treatment of RIF is crucial because current medical approaches do not reliably slow or reverse RIF. In recent years, many experts have worked to identify herbs or herbal extracts to combat RIF both in vivo and in vitro, with some success. This review attempts to summarize the possible interventional mechanisms of herbs or herbal extracts involved in protecting and reversing RIF. The authors found some herbs and their extracts that may ameliorate renal impairments through anti-inflammation, anti-fibrogenesis and stabilization of extra cellular matrix. Among them, tetramethylpyrazine/ligustrazine, curcumin and polyglucoside of Tripterygium have experimentally shown good potential for improving RIF. However, conclusive evidence is still needed, especially in randomized controlled clinical trials. We expect that herbs or herbal extracts will play an important role in RIF treatment and reversal in the future.

- Abstract
Objective: To explore the underlying mechanism of "Gubentongluo Formula" in treatment of IgA nephropathy (IgAN)., Methods: After the IgAN model was successfully induced at week 12, the Kunming mice were randomly divided into three groups: normal control group (n = 15), IgAN group (n = 15) and Traditional Chinese Medicine (TCM) group. The mice in normal control and IgAN group were intragastriclly administrated with normal saline for 8 weeks; meanwhile, the mice in TCM group were intragastriclly administrated with "Gubentongluo Formula" 1.35 mL/ (g · d). The levels of 24 h urine protein were determined at Week 0, 12 and 20. At week 20, the changes of renal pathology were detected; the mRNA expressions of transforming growth factor-β (TGF-β) and small mothers against decapentaplegic (Smad) 3 in Peyer's patches (PPs) were detected by fuorescent quantitative reverse transcription-polymerase chain reaction; the protein expressions of TGF-β and Smad 3 in PPs were detected by immunohistochemistry technique; the levels of (IgA + B)/B lymphocytes in PPs were determined by flow cytometry., Results: Compared with those results of normal control group, the levels of 24 h urine protein, IgA deposition in glomerular mesangial area, and expressions of protein and mRNA of TGF-β and Smad3 in IgAN group were significantly increased (P < 0.01). Besides, the levels of (IgA+B)/B lymphocytes were significantly elevated in IgAN group (P < 0.01). All these indicators were improved in TCM group. Compared with IgAN group, the differences were statistically significant (P < 0.01). Compared with those results of control group, the levels of (IgA + B)/B lymphocytes showed no significant difference in TCM group (P > 0.05), but other indicators showed significant differences (P < 0.01)., Conclusion: "Gubentongluo Formula" could effectively improve proteinuria and suppress IgA deposition in glomerular mesangial area in IgAN mice, due to affect IgA class switch recombination of B lymphocytes in PPs through regulating TGF-β/Smad3 pathway.

- Abstract
Aim: Aberrantly glycosylated IgA1 is a key factor in the pathogenesis of IgA nephropathy (IgAN). In this study we investigated the effects of aggregated IgA1 derived from IgAN patients (P-aIgA1) on human renal mesangial cells (HMCs) and the anti-proliferative and antifibrotic effects of histone deacetylase (HDAC) inhibitors in vitro., Methods: Three types of IgA1 were prepared, ie, N-IgA1 (IgA1 from healthy volunteers), P-IgA1 (IgA1 from IgAN patients), and P-aIgA1 (aggregated IgA1 from IgAN patients). The isolated IgA1 was heated for thermal polymerization. The proliferation of human renal mesangial cells (HMCs) were assessed using MTT assay. The expression levels of relevant proteins were examined using immunoblotting assays or immunohistochemistry., Results: P-aIgA1 (25-250 μg/mL) dose-dependently promoted the proliferation of HMCs, and markedly increased the protein levels of type I histone deacetylase (HDAC1, HDAC2 and HDAC8) in the cells. Both P-IgA1 and N-IgA1 were much weaker in stimulating cell proliferation and HDAC expression. P-aIgA1 (50 μg/mL) markedly increased the protein levels of Col1a1 and PAI-1, as well as pSmad2/3 and pStat3 in the cells. Pretreatment with the HDAC inhibitor trichostatin A (TSA, 250 nmol/L) or valproic acid (VPA, 400 μg/mL) partially reversed P-aIgA1-induced cell proliferation and extracellular matrix synthesis in HMCs., Conclusion: P-aIgA1 produces pro-proliferative and profibrotic actions in HMCs via upregulating the expression of HDACs, and subsequently activating TGF-β/Smad2/3 and Jak2/Stat3 signaling pathways. Both VPA and TSA attenuate P-aIgA1-induced cell proliferation and fibrosis in HMCs.

- Abstract
The Groucho transcriptional co-repressor TLE4 protein has been shown to be a tumor suppressor in a subset of acute myeloid leukemia. However, little is known about its role in development and progression of solid tumor. In this study, we found that the expression of TLE4 in colorectal cancer (CRC) tissues was significantly higher than that in their matched adjacent intestine epithelial tissues. In addition, high expression of TLE4 was significantly correlated with advanced Dukes stage, lymph node metastasis and poor prognosis of CRC. Moreover, enforced expression of TLE4 in CRC cell lines significantly enhanced proliferation, invasion and tumor growth. On the contrary, knock down of TLE4 repressed cell proliferation, invasion and tumor growth. Furthermore, our study exhibited that the TLE4 promoted cell proliferation and invasion partially via activation of JNK-c-Jun pathway and subsequently increased cyclinD1 and decreased P27Kip1 expression. In conclusion, these results suggested that TLE4, a potential prognostic biomarker for CRC, plays an important role in the development and progression of human CRC.
