Background: LncRNA NEAT1 has been identified as a tumour driver in many human cancers. However, the underlying mechanism of lncRNA NEAT1 in diffuse large B-cell lymphoma (DLBCL) progression is unclear., Methods: The expression levels of NEAT1, GLI1 and miR-34b-5p were detected by RT-qPCR and Western blotting in DLBCL tissues and cell lines. MTT and colony formation assays were performed to examine cell proliferation, while annexin-V staining and TUNEL assays were performed to measure cell apoptosis. The effect of NEAT1, GLI1 and miR-34b-5p on cell cycle-associated proteins was evaluated by Western blotting. Dual-luciferase reporter and RNA immunoprecipitation (RIP) assays were employed to investigate the interaction between NEAT1 and miR-34b-5p or GLI1 and miR-34b-5p. Moreover, chromatin immunoprecipitation (ChIP) was performed to demonstrate the interaction between MYC and NEAT1., Results: NEAT1 and GLI1 were upregulated while miR-34b-5p was downregulated in DLBCL tissues and cell lines compared to normal controls. Knockdown of NEAT1 or overexpression of miR-34b-5p inhibited cell proliferation but promoted cell apoptosis. Overexpression of NEAT1 reversed GLI1-knockdown induced attenuation of cell proliferation. In other words, NEAT1 acted as a competing endogenous RNA (ceRNA), regulating the miR-34b-5p-GLI1 axis, further affecting the proliferation of DLBCL. Moreover, MYC modulated NEAT1 transcription by directly binding to the NEAT1 promoter., Conclusion: We revealed that MYC-regulated NEAT1 promoted DLBCL proliferation via the miR-34b-5p-GLI1 pathway, which could provide a novel therapeutic target for DLBCL., Competing Interests: Competing interestsThe authors declare that they have no conflict of interests., (© The Author(s) 2020.)

Background: The positive predictive value (PPV) of urinary decoy cells for diagnosing BK polyomavirus associated-nephropathy (BKPyVAN) is low. This study was designed to increase the PPV of urinary decoy cells for diagnosing BKPyVAN in kidney transplant recipients., Methods: A total of 105 urine sediment samples from 105 patients with positive BK viruria and decoy cells were evaluated by automatic double-immunostaining with anti-HGD (a renal tubular marker) antibody + anti-SV40-T antibody or anti-S100P (an urothelial marker) antibody + anti-SV40-T antibody., Results: Of the 105 patients, 76 (72.4%) had both HGD(+)/SV40-T(+) cells and S100P(+)/SV40-T(+) cells (group A), 24 (22.9%) had only S100P(+)/SV40-T(+) cells (group B), and 5 (4.6%) had only S100P(-)/HGD(-)/SV40-T(+) cells (group C). Seventy patients in group A (92.1%), 3 patients in group B (12.5%), and no patients in group C were diagnosed with BKPyVAN. The area under the ROC curve of predicting BKPyVAN by decoy cells was 0.531 (0.431-0.630), with an optimal cut-off value of 29 (per 10 high power field), a sensitivity of 45.8% (95% CI: 34.0-58.0%), and a specificity of 68.8% (95% CI: 50.0-83.9%). Besides, the area under the ROC curve of predicting BKPyVAN by plasma BKPyV load was 0.735 (95% CI: 0.632-0.822), with an optimal cut-off value of 1,000 copies/mL, a sensitivity of 61.1% (95% CI: 48.9-72.4%) and a specificity of 84.2% (95% CI: 60.4-96.6%). In contrast, the PPV, negative predictive value, sensitivity, and specificity of HGD(+)/SV40-T(+) cells for diagnosing BKPyVAN were 92.1% [95% confidence interval (CI): 83.0-96.7%], 89.7% (95% CI: 71.5-97.3%), 95.9% (95% CI: 87.7-98.9%), and 81.3% (95% CI: 63.0-92.1%) respectively., Conclusions: Double-immunostaining with anti-HGD or anti-S100P and anti-SV40-T antibodies helps to identify the origin of decoy cells and diagnose BKPyVAN., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare., (2020 Annals of Translational Medicine.

Objective: Atherosclerosis (AS), with high risk of stroke or cerebrovascular disease, is one of the most common causes of death worldwide. Increasing evidence shows that long non-coding RNA (lncRNA) antisense non-coding RNA in the INK4 locus (ANRIL) is related to atherothrombotic stroke susceptibility and contributes to AS progression. However, the underlying mechanism was not explained yet., Patients and Methods: Human aorta vascular smooth muscle cells (HA-VSMCs) and human umbilical vein endothelial cells (HUVECs) were treated with oxidized Low Density Lipoprotein (ox-LDL) and considered as AS cell models. Quantitative reverse transcriptase PCR (qRT-PCR) and Western blotting were employed to investigate the mRNA and protein expression level, respectively. Microscopic examination through fluorescent in situ hybridization (FISH) was used to determine the location of ANRIL. Cell proliferation and migration assays were demonstrated to evaluate the functional role of ANRIL in AS. Potential target of ANRIL was determined using Luciferase reporter assay and RNA immunoprecipitation (RIP)., Results: ANRIL was upregulated and miR-399-5p was down-regulated in both human atherosclerotic plaques and ox-LDL-induced cells. ANRIL was located in cytoplasm and promoted cell proliferation and migration by sponging miR-399-5p. Further analysis identified fibroblast growth factor receptor substrate 2 (FRS2) as a direct target of miR-399-5p. Finally, RAS/RAF/ERK signal pathway was proved to be involved in the regulation of ANRIL on the progression of AS., Conclusions: These results revealed the underlying mechanism that ANRIL promoted AS progression by sponging miR-399-5p and regulating RAS/RAF/ERK signal pathway, suggesting that ANRIL might be a potential target for the therapeutic strategy of AS.

The aim of the present study was to compare the safety and efficacy of cryoablation (CA) and microwave ablation (MWA) as treatments for non-small cell lung cancer (NSCLC). Patients with stage IIIB or IV NSCLC treated with CA (n=45) or MWA (n=56) were enrolled in the present study. The primary endpoint was progression-free survival (PFS); the secondary endpoints included overall survival (OS) time and adverse events (AEs). The median PFS times between the two groups were not significantly different (P=0.36): CA, 10 months [95% confidence interval (CI), 7.5-12.4] vs. MWA, 11 months (95% CI, 9.5-12.4). The OS times between the two groups were also not significantly different (P=0.07): CA, 27.5 months (95% CI, 22.8-31.2 months) vs. MWA, 18 months (95% CI, 12.5-23.5). For larger tumors (>3 cm), patients treated with MWA had significantly longer median PFS (P=0.04; MWA, 10.5 months vs. CA, 7.0 months) and OS times (P=0.04; MWA, 24.5 months vs. CA, 14.5 months) compared patients treated with CA. However, for smaller tumors (≤3 cm), median PFS (P=0.79; MWA, 11.0 months vs. CA, 13.0 months) and OS times (P=0.39; MWA, 30.0 months vs. CA, 26.5 months) between the two groups did not differ significantly. The incidence rates of AEs were similar in the two groups (P>0.05). The number of applicators, tumor size and length of the lung traversed by applicators were associated with a higher risk of pneumothorax and intra-pulmonary hemorrhage in the two groups. Treatment with CA resulted in significantly less intraprocedural pain compared with treatment with MWA (P=0.001). Overall, the present study demonstrated that CA and MWA were comparably safe and effective procedures for the treatment of small tumors. However, treatment with MWA was superior compared with CA for the treatment of large tumors., (Copyright © 2020, Spandidos Publications.)

We describe three new species of Pareuchiloglanis. Based on a comparison of 17 valid species of Pareuchiloglanis, the genus can be divided into two groups contingent on their gill opening size and the anus position. One group, which we call the large gill opening group, has a large gill opening extending to the base of the first pectoral-fin element; the anus is obviously closer to pelvic-fin insertion than the anal-fin origin; this group includes five species distributed in the Red and Pearl Rivers, China. The other group has a small gill opening extending only to the middle base of the pectoral-fin elements; the anus is usually located at the midpoint of the pelvic-fin insertion to the anal-fin origin or slightly behind. This group includes the other 12 species, which are distributed in the Mekong and Yangtze Rivers. The large-gill-opening group can be divided into two sub-groups based on the length of the caudal peduncle. One sub-group has a long caudal-peduncle and the distance from the anal-fin origin to caudal-fin base is greater than distance from the pelvic-fin insertion. This sub-group is only distributed in the Pearl River drainage. Another sub-group has a short caudal peduncle and the distance from the anal-fin origin to the caudal-fin base is typically smaller than the distance from the pelvic-fin insertion. This sub-group is only distributed in the Red River basin of China and Vietnam. The former will be called the large-gill-opening group with long caudal peduncle in the text and only includes one species P. longicauda. During our ongoing taxonomic work of specimens collected from Nanpan-jiang and Beipan-jiang (upper Pearl River drainage in Yunnan, China), some Pareuchiloglanis specimens that had the characters of the large-gill-opening group with long caudal peduncle represent three undescribed species., (© 2019 The Fisheries Society of the British Isles.)

Bay cities have abundant land-sea resources and higher environmental carrying capacity. The high density of population and industry surrounding the bay makes bay cities a type of ecologically fragile areas. With Quanzhou, a typical bay city, as an example, we simulated the land use and landscape pattern change in 2030 based on multiple data sources (land use data, meteorological site data, topographic data and statistical data) using Logistic-CA-Markov coupling model to set natural scenarios, planning scenarios and protection scenarios. Four key ecosystem service (ES) including water retention, soil conservation, carbon sequestration (NPP), food supply and their trade-offs were calculated and predicted. Under the three scenarios, the area of cultivated land and construction land in Quanzhou City would increase in 2030. Forest land, grassland and water area would be reduced in varying degrees. The fragmentation of land use would be serious. In comparison with 2015, except for soil conservation service, water retention, carbon sequestrtion and food supply of Quanzhou City would decline to varying degrees in 2030. Ecosystem service function in natural scenario would be more decreased, with the decline under the protection scenario being lower than the planning scenario. In the protection and planning scenarios, the synergy between water conservation and soil conservation, water conservation and carbon sequestrtion, soil conservation and carbon sequestrtion in 2030 would be enhanced and the trade-offs would be weakened.

The objective of the present study was to explore the effects of environmental chemicals, such as methyl mercury, paraquat, and bisphenol A, on cell proliferation and apoptosis, as well as the expression levels of neuronal differentiation-related genes in neural stem cells (NSCs). NSCs originated from human umbilical cord blood (HUCB-NSCs) were used as cell models in the current study. CCK-8 and flow cytometry experiments were performed to assess the effects of methyl mercury, paraquat, and bisphenol A on the proliferation and apoptosis of HUCB-NSCs at different processes, including proliferation and differentiation stages. The expressions of neuronal differentiation-related genes were determined by reverse transcription-polymerase chain reaction and western blot analysis. The results showed that methyl mercury, paraquat, and bisphenol A treatments significantly inhibited cell proliferation and induced cell apoptosis in HUCB-NSCs, as well as decreased the expressions of Oct4, Gdf3, and Sox1, whereas increased Pax6 and Ngn1 expressions at both mRNA and protein levels. In conclusion, this study demonstrates that environmental chemicals can impair the proliferation and differentiation of NSCs, which may cause abnormal development of the nervous system., (© 2019 Wiley Periodicals, Inc.)

Background: The effect of short-segment decompression/fusion versus long-segment decompression/fusion and osteotomy for Lenke-Silva type VI adult degenerative scoliosis (ADS) has not been clarified. This study aimed to compare the clinical and radiographic results of short-segment fusion vs. long-segment fusion and osteotomy for patients with Lenke-Silva type VI ADS., Methods: Data of 28 patients who underwent spinal surgery for ADS from January 2012 to January 2014 in the General Hospital of Northern Theater Command were reviewed. Of the 28 patients, 12 received long-segment fusion and osteotomy and 16 received short-segment fusion. Radiographic imaging parameters and clinical outcomes, including the sagittal vertical axis (SVA), lumbar lordosis (LL) angle, pelvic tilt (PT), sacral slope (SS), the visual analog scale (VAS), Japanese Orthopedic Association (JOA), Oswestry disability index (ODI), and lumbar stiffness disability index (LSDI) scores, were recorded. The difference between groups was compared using the dependent t test or Chi-squared test., Results: The Cobb and LL angles and SVA improved in both groups; however, PT and SS angles did not improve following short fusion. There were significant differences in the post-operative SVA (26.8 ± 5.4 mm vs. 47.5 ± 7.6 mm, t = -8.066, P < 0.001), PT (14.7 ± 1.8° vs. 29.1 ± 3.4°, t = -13.277, P < 0.001), and SS (39.8 ± 7.2° vs. 26.1 ± 3.3°, t = 6.175, P < 0.001) between the long and short fusion groups. All patients had improved ODI, JOA, and VAS scores post-operatively (all P < 0.001), with no significant difference between the groups (all P > 0.05). The post-operative LSDI score was 3.5 ± 0.5 in the long fusion group, which was significantly higher than that of the short fusion group (1.4 ± 0.7; P < 0.001)., Conclusions: The clinical outcomes of patients with Lenke-Silva type VI ADS who underwent short-segment decompression/fusion were comparable to those of patients who underwent long-segment decompression/fusion and osteotomy despite poor correction of sagittal imbalance. Moreover, short-segment decompression/fusion showed a short operation time and reduced surgical trauma.

Background: Willis covered stents are used in clinical practice for some complex cerebrovascular diseases. However, the performance of the Willis covered stent requires further investigation. In this study, we investigate the safety and efficacy of Willis covered stents for the treatment of complex vascular diseases of the internal carotid artery (ICA)., Methods: Thirteen patients with complex ICA diseases treated with the Willis covered stent system at our institution from October 2016 to January 2018 were analyzed retrospectively. Follow-up observation and digital subtraction angiography (DSA) examination were conducted at about 6-10 months after the treatment., Results: The complex vascular diseases of the ICA were successfully treated in 12 patients. The technical success rate was 92.3%. Pathologically, 13 lesions included blood blister-like aneurysm (n = 7), traumatic pseudoaneurysm (n = 1), traumatic carotid artery rupture (n = 1), and aneurysm with arteriovenous fistula (n = 4). Thirteen patients with complex vascular diseases of the ICA were treated with 15 Willis covered stents. The release sites of Willis covered stents were the C7 (n = 2), C6 (n = 1), C5 and/or C4 (n = 9), and the C2 (n = 3) segment of the ICA. DSA performed immediately after stent deployment revealed that complete occlusion of the lesion was achieved in 11 patients and endoleak was observed in 2 patients. Of the 11 patients, postoperative DSA examination indicated that the lesions were occluded completely. Among 2 patients, who had a second stent implantation at the break of the ICA, the traumatic ICA rupture was essentially completely obstructed in 1 patient. The endoleak remained in 1 patient with carotid cavernous sinus fistula because the placement of the second stent system was difficult with his ICA tortuosity. No recurrence of aneurysms, hemorrhagia, and other lesions was observed, and the patients' parent arteries were patent without stenosis. No procedure-related complications or deaths occurred during follow-up., Conclusions: For the treatment of complex vascular diseases in the ICA, Willis covered stent implantation is safe and effective. However, longer follow-up, large-sample controlled studies, and multicenter studies are needed for further confirmation., (Copyright © 2019 The Authors. Published by Elsevier Inc.

The prevalence of obesity was increasing and became a growing problem worldwide. Obesity increased the risk of developing metabolic abnormalities and was associated adverse health outcomes. Our aim was to examine the associations among different combinations of obesity phenotypes (high body mass index > 27 kg/m 2 (O), high waist circumference (male > 90 cm, female > 80 cm) (W), fatty liver (F) and percentage body fat in top 40% (P)) and cardiometabolic diseases (type 2 diabetes mellitus (DM), hypertension (HTN), metabolic syndrome (MetS)). A total of 48426 eligible subjects were categorized based on the different definitions. After adjusting for all covariables, participants with O + F + P combination were more likely associated with the presence of DM. Participants with O + W combination were more associated with the presence of HTN than others. Participants with O + W + F + P had higher risk for the presence of MetS than others. The study addressed the associations between different obesity phenotypes and DM and HTN in the adult population. Better understanding the pathophysiological mechanisms underlined individual vulnerability and progression of cardiometabolic insults.

The present study investigated the antiapoptotic and antigenotoxic capabilities of N-acetyl cysteine- (NAC-) containing polymethyl methacrylate (PMMA) resin. An in vitro Transwell insert model was used to mimic the clinical provisional restorations placed on vital teeth. Various parameters associated with cell apoptosis and genotoxicity were investigated to obtain a deeper insight into the underlying mechanisms. The exposure of human dental pulp cell (hDPC) cultures to the PMMA resin (Unifast Trad™) resulted in a rapid increase in reactive oxygen species (ROS) level beginning at 1 h, which was followed by time-dependent cell detachment and overt death. The formation of γ -H 2 AX and cell cycle G1 phase arrest indicated that oxidative DNA damage occurred as a result of the interactions between DNA bases and ROS, beyond the capacities of cellular redox regulation. Such oxidative DNA damage triggers the activation of p53 via the ataxia telangiectasia mutated (ATM) signaling pathway and the induction of intrinsic mitochondrial apoptosis. Oxidative stress, cell apoptosis, and DNA damage induced by the PMMA resin were recovered to almost the level of untreated controls by the incorporation of NAC. The results indicate that the PMMA resin induced the intrinsic mitochondrial apoptosis as a consequence of p53 activation via the ATM pathway in response to oxidative DNA damage. More importantly, the incorporation of NAC as a novel component into the Unifast Trad™ PMMA resin offers protective effects against cell apoptosis and genotoxicity. This procedure represents a beneficial strategy for developing more biocompatible PMMA-based resin materials., Competing Interests: The authors declare no conflict of interest., (Copyright © 2019 Yu Zhang et al.)

Recent studies have shown that microcystin-LR (MC-LR) is one of the principal factors that cause liver cancer. Previously we have found that Aristaless-like Homeobox 4 (ALX4) was differentially expressed in MC-LR-induced malignant transformed L02 cells. However, the expression regulation, role and molecular mechanism of ALX4 during the process of liver cancer induced by MC-LR are still unclear. The expression of ALX4 was detected by quantitative reverse-transcription PCR and Western blot in MC-LR induced malignantly transformed cell and rat models. Methylation status of ALX4 promoter region was evaluated by methylation-specific PCR and bisulfite genomic sequencing. The anti-tumor effects of ALX4 on MC-LR induced liver cancer were identified in vitro and in vivo. ALX4 expression was progressively down-regulated in MC-LR-induced malignantly transformed L02 cells and the MC-LR exposed rat models. ALX4 promoter regions were highly methylated in malignantly transformed cells, while treatment with demethylation agent 5-aza-dC significantly increased ALX4 expression. Functional studies showed that overexpression of ALX4 inhibits cell proliferation, migration, invasion and metastasis in vitro and in vivo, blocks the G1/S phase and promotes the apoptosis. Conversely, knockdown of ALX4 promotes cell proliferation, migration and invasion. Mechanism study found that ALX4 exerts its antitumor function through the P53 pathway, C-MYC and MMP9. More importantly, ALX4 expression level showed a negative relation with serum MC-LR levels in patients with hepatocellular carcinoma. Our results suggested that ALX4 was inactivated by DNA methylation and played a tumor suppressor function through the P53 pathway in MC-LR induced liver cancer., (Copyright © 2019 Elsevier B.V.

Epilepsy is one of the most common neurological disorders in humans. Recently, long noncoding RNAs (lncRNAs) have been reported to be important players in neurological diseases. Herein, this study aimed to examine the effect of lncRNA GAS5 on the occurrence of epilepsy in rat and cell models of epileptic seizure. The expression of lncRNA GAS5 was measured in the established rat and cell models. The binding sites between lncRNA GAS5 and miR-135a-5p, as well as those between miR-135a-5p and 3' untranslated region of KCNQ3 were predicted by miRDB and Targetscan, separately, followed by verification using dual-luciferase reporter gene assay. The expression of miR-135a-5p was measured in response to the overexpression of lncRNA GAS5. The mRNA and protein levels of KCNQ3 were examined in response to overexpression of miR-135a-5p. Next, the latency of epilepsy and frequency of epileptic seizures were assessed in rats injected with Lv-shGAS5 and Lv-miR-135a-5p in epileptic seizure model. In the rat and cell models, lncRNA GAS5 was highly expressed when epileptic seizure was induced. The expression of miR-135a-5p was decreased by overexpression of lncRNA GAS5. Meanwhile, the mRNA and protein levels of KCNQ3 were decreased in response to knockdown of miR-135a-5p. After the treatment of Lv-shGAS5 and Lv-miR-135a-5p, the average latent period of epilepsy was prolonged and the frequency of seizures was decreased. The key findings of the present study provide evidence emphasizing that lncRNA GAS5 functions as a competitive endogenous RNA of miR-135a-5p to increase expression of KCNQ3, and lncRNA GAS5 silencing inhibited the occurrence and progression of epilepsy., (© 2019 The Authors.

Objective: To investigate the expression of β-catenin in the skin lesions of patients with systemic scleroderma (SSc) and its effect on epithelial-mesenchymal transition (EMT) of human epidermal keratinocytes., Methods: The expression of β-catenin, Snail1 and E-cadherin in the skin lesions sample of 45 SSc patients and normal skin sample from 20 healthy adults was detected with SP immunohistochemistry. HaCaT, the human epidermal keratinocytes, were treated with different concentrations of Wnt10b (0 ng/mL (control), 2 ng/mL and 4 ng/mL) for 48 h. then detected the localization of β-catenin in HaCaT cells by immunofluorescence assay, determined the mRNA levels of Snail1 and Snail2 in HaCaT cells by real-time fluorescent quantitative PCR, detected the proteins expression of β-catenin, Vimentin, N-cadherin and E-cadherin in HaCaT cells by Western blot., Results: The positive rates of β-catenin, Snail1 and E-cadherin in skin lesions of SSc patients were 100%, 88.89% and 2.22% respectively, while in healthy adult skin, the corresponding positive rates were 0%, 10.00%, and 95.00%. The difference between the two groups was significant. Compared with control group, treatment with different concentrations of Wnt10b (2 ng/mL and 4 ng/mL) induced up-regulation of β-catenin expression and promoted translocation of β-catenin from cytoplasm to nucleus, increased the mRNA levels of Snail1 and Snail2 ( P < 0.05), and up-regulated the proteins expression of Vimentin, N-cadherin, down-regulated the E-cadherin protein expression in HaCaT cells ( P < 0.05)., Conclusions: Abnormally activated Wnt/β-catenin signaling pathway and abnormally expressed EMT-related proteins are observed in SSc lesions. Activation of Wnt/β-catenin signaling pathway may promote EMT in HaCaT cells., (Copyright© by Editorial Board of Journal of Sichuan University (Medical Science Edition).)

Surface Fermi arcs (SFAs), the unique open Fermi-surfaces (FSs) discovered recently in topological Weyl semimetals (TWSs), are unlike closed FSs in conventional materials and can give rise to many exotic phenomena, such as anomalous SFA-mediated quantum oscillations, chiral magnetic effects, three-dimensional quantum Hall effect, non-local voltage generation and anomalous electromagnetic wave transmission. Here, by using in-situ surface decoration, we demonstrate successful manipulation of the shape, size and even the connections of SFAs in a model TWS, NbAs, and observe their evolution that leads to an unusual topological Lifshitz transition not caused by the change of the carrier concentration. The phase transition teleports the SFAs between different parts of the surface Brillouin zone. Despite the dramatic surface evolution, the existence of SFAs is robust and each SFA remains tied to a pair of Weyl points of opposite chirality, as dictated by the bulk topology.

Background: Delirium is very common among patients with polytrauma, although no suitable means exist to feasibly reduce the incidence and duration of delirium in these patients. Recent reports have suggested that continuous intravenous (IV) infusions of dexmedetomidine, rather than benzodiazepine, be administered for sedation to reduce the duration of delirium in this population. However, serum neuron-specific enolase (NSE), S100 calcium binding protein B (S100B), and brain-derived neurotrophic factor (BDNF) levels have not yet been investigated in polytrauma patients who received sedation with dexmedetomidine rather than other conventional sedatives. The aim of this study was to assess the association of blood BDNF, NSE, and S100B with the occurrence of delirium among polytrauma patients who had been sedated with dexmedetomidine., Materials and Methods: Consecutive patients were randomly assigned to 1 of 2 treatment study groups, namely the "dexmedetomidine group" or the "common group." This case-control study included 18 patients with delirium and 34 matched controls in a 63-bed general intensive care unit (ICU). Blood samples were collected from all patients upon ICU admission, on the day when delirium was diagnosed, and on days 3 and 5 following diagnosis. The serum levels of S100B, BDNF, and NSE were determined by enzyme-linked immunosorbent assay. The sedation levels and delirium were assessed using the Richmond Agitation and Sedation Scale and the Confusion Assessment Method for the ICU., Results: The median BDNF, NSE, and S100B concentrations were significantly lower in the dexmedetomidine group than in the common group on the day when delirium was diagnosed and on the third day after delirium was diagnosed. The rate of delirium was significantly lower in the dexmedetomidine group than in the common group. There were clear differences in the BDNF, NSE, and S100B levels between the 2 groups on the fifth day after delirium was diagnosed., Conclusions: Our randomized controlled study suggests that the sedation of polytrauma patients with dexmedetomidine could help reduce the serum BDNF, S100B, and NSE levels, which appear to be associated with the occurrence of delirium in the dexmedetomidine group.

In order to explore the composition, sources and ecological risks of polycyclic aromatic hydrocarbons (PAHs) in water from Yinchuan wetlands, water samples were collected in the dry season and plentiful season from 15 wetlands. Sixteen species of PAHs were analyzed by gas-mass spectrometry, and source identification of PAHs was investigated by PCA and EPA positive matrix factorization 5.0. Ecological risk was assessed using the risk entropy method based on the neglected concentrations (NCs) and the maximum permissible concentrations (MPCs). The results showed that:① in the dry season, eight kinds of PAHs were detected, the concentrations of which ranged from 1455.38 ng·L -1 to 2538.84 ng·L -1 . In the plentiful season, 12 kinds of PAHs were detected, the concentrations of which ranged from 818.69 ng·L -1 to 1582.14 ng·L -1 . The concentrations of PAHs in the dry season in Yinchuan were higher than that during the plentiful season. Compared with other domestic and overseas surface waters, PAH pollution was high; ② in the dry season, PAHs were mainly composed of 3-5 rings, and 2-3 and 4-6rings accounted for 35.6%-59.2% and 40.8%-59.7%, respectively. In the plentiful season, PAHs were mainly composed of 4-5 rings, and 2-3 and 4-6rings accounted for 10.2%-45.07% and 54.92%-89.76%, respectively; ③ the source analysis showed that in both the dry season and in the plentiful season, the main source were combustion and automobile emissions; ④ the ecological risk assessment indicated that the RQ MPCs of BaA, BbF, InP, DBA, and BghiP during both the dry and plentiful seasons, and RQ MPCs of Phe during the dry season, were higher than 1.0, indicating that attention needs to be paid to pollution levels. The RQ NCs of Nap, Ace, Fla, Pyr, and BaP during the plentiful season and the RQ NCs of Nap during the dry season were higher than 1.0, indicating the pollution risk was moderate and control and prevision of pollution from PAHs are required in the region.

Aim: To explore the association between vestibular dysfunction and specific anthropometric parameters., Methods: The results from 2420 participants of the 1999-2004 National Health and Nutrition Examination Survey were included for the evaluation of vestibular dysfunction using the Romberg test of standing balance and anthropometric measurements, including waist circumference, thigh circumference, calf circumference (CC), waist-to-thigh ratio (WTR) and waist-to-calf ratio (WCR). Passing the balance test was defined as participants keeping their balance for 30 s while in the standing position with their eyes closed. Multivariable logistic regression models were the main statistical tools in the present study., Results: The mean age of the participants was approximately 65 years, and half of the study participants were men. The full adjusted odds ratio of vestibular dysfunction for the CC, thigh circumference, WCR and WTR was 0.941 (95% confidence interval [CI], 0.894-0.992), 0.948 (95% CI 0.912-0.986), 1.856 (95% CI 1.087-3.170) and 2.516 (95% CI 1.235-5.126), respectively. Higher waist circumference along with lower thigh circumference and CC were observed in the participants in the higher WTR and WCR quartiles. Furthermore, a dose-response relationship between vestibular dysfunction and anthropometric ratios was detected., Discussion: The present study showed that individuals with lower CC and thigh circumference or higher WCR and WTR exhibited higher odds of having vestibular dysfunction.

Aim: To evaluate the accuracy and complications of computed tomography (CT)-guided core needle biopsy (CNB) of small (≤20 mm) subpleural pulmonary lesions with the use of the long transpulmonary needle path., Materials and Methods: A retrospective study was undertaken comprising 235 patients who underwent CT-guided CNB of small (≤20 mm) subpleural pulmonary lesions. One of two needle paths was used: a long (≥10 mm) transpulmonary needle path (n=164, group A) or a short (<10 mm) transpulmonary needle path (n=71, group B). Diagnostic accuracy, pneumothorax, and bleeding rates were compared between the two groups., Results: The diagnostic accuracy in group A was significantly higher than that in group B (93.9% versus 81.7%, p=0.004), particularly in patients with 5-10 mm lesions (89.2% versus 53.3%, p=0.013). The mean length of the transpulmonary needle path was 23.9 mm in group A and 5.9 mm in group B (p<0.001). The mean number of pleural punctures in group A was 1.01 and 1.11 in group B (p=0.016), but for patients with more than one puncture, the short transpulmonary path was not associated with a higher accuracy rate. The incidence of bleeding was 22% in group A and 9.9% in group B (p=0.028)., Conclusion: Diagnostic accuracy for small subpleural pulmonary lesions with the use of the long transpulmonary needle path was higher than that with the use of the short transpulmonary needle path, especially for 5-10 mm lesions; however, the long transpulmonary needle path was associated with a higher rate of bleeding., (Copyright © 2019.

Although different treatment methods have been introduced to treat advanced pancreatic carcinoma, the median overall survival rate remains unsatisfactory. Theoretically, combining different treatment methods should work in synergy to enhance locoregional disease control and improve survival. Therefore, the aim of the present retrospective study was to analyze the effectiveness of combined interventional therapy compared with trans-arterial chemoembolization (TACE) or chemotherapy alone for the treatment of unresectable pancreatic carcinoma. A total of 266 patients who were undergoing treatment for unresectable pancreatic carcinoma between July 2012 and November 2015 were included in the current study. The tumor responses and 3-year overall survival rates of patients treated with combined interventional therapy (TACE combined with iodine-125 seed implantation and/or radiofrequency ablation; CIT group; n=84) were compared with those of patients treated with TACE alone (TACE group; n=59), as well as patients treated with systemic chemotherapy alone (control group; n=123). Patients in the CIT group exhibited significantly improved tumor responses compared with patients in the TACE group (51.89 vs. 30.61%; P=0.028) or control group (51.89 vs. 17.20%; P<0.001). The 3-year overall survival rate of the CIT group was also significantly higher compared with that of the TACE and control groups (P=0.0116 and P=0.0001, respectively). Furthermore, the CIT group exhibited a significantly higher overall survival rate for patients with unresectable metastatic pancreatic cancer compared with the TACE and control groups (P=0.0088 and P<0.0001, respectively), which suggests that a combination of different interventional techniques increases the survival of patients with unresectable pancreatic cancer. No life-threatening complications were observed in any treatment group. In conclusion, combined interventional therapy exhibits a good efficacy and an improved survival rate for unresectable pancreatic cancer compared with TACE alone.

Accumulating evidence indicates the association between obesity and lung function. However, no previous study has examined whether obesity affects lung function in normal weight participants with high body fat. We hypothesized that subjects with normal weight obesity (NWO) were inversely associated with lung function in Taiwan. The study sample was composed of participants who attended health examinations at the Tri-Service General Hospital from 2010 to 2016. A total of 7801 eligible participants who were classified as NWO were divided into quartiles by percentage body fat (PBF), which was measured by bioelectrical impedance analysis (BIA). A multivariable linear regression was performed to assess the association between PBF quartiles and pulmonary function. The relationship between PBF and the presence of obstructive and restrictive lung diseases was analyzed by a logistic regression. PBF quartiles were closely associated with reduced forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) in all adjusted models. This relationship remained significant in the male population, and a dose-dependent effect was observed. Increased PBF was associated with increased risks for the presence of restrictive lung diseases. These results presented a novel finding that body fat exhibited an inverse association with pulmonary function in NWO subjects. More comprehensive management of subjects with normal weight but high body fat, which might contribute to metabolic dysfunction and impaired pulmonary function, is needed.

The pharmacokinetics of a diclofenac sodium was investigated in swine. A single intravenous (i.v.) or intramuscular (i.m.) injection of 5% diclofenac sodium (concentration = 2.5 mg · kg-1) was administered to 8 healthy pigs according to a two-period crossover design. The pharmacokinetic parameters were calculated by non-compartmental analysis with DAS2.1.1 software. After a single i.v. administration, the main pharmacokinetic parameters of diclofenac sodium injection in swine were as follows: the elimination half-time (T1/2β) was 1.32±0.34 h; the area under the curve (AUC) was (55.50±5.50 μg · mL-1 h; the mean residence time (MRT) was 1.60±0.28 h; the apparent volume of distribution (Vd) was 0.50±0.05 L · kg-1; and the body clearance (CLB) was 0.26±0.04 L · (h · kg)-1. After the single i.m. administration, the pharmacokinetic parameters were as follows: peak time (Tmax) was 1.19±0.26 h; and peak concentration (Cmax) was 11.61±5.99 μg mL-1. The diclofenac sodium has the following pharmacokinetic characteristics in swine: rapid absorption and elimination; high peak concentration; and bioavailability., (Copyright© by the Polish Academy of Sciences.)

Objective: To elucidate whether the peripheral fat (PF)-combined definition of metabolic syndrome (MetS) would show a better predictive ability for cause-specific mortality than the common MetS., Methods: Data were derived from the National Health and Nutrition Examination Survey from 1999 through 2002. We investigated three types of MetS including waist circumference MetS (WCMetS), PFMetS, and PF-combined definition of MetS. The main outcome was to evaluate the predictive ability of the newly defined MetS for time to cause-specific mortality. The secondary outcomes were the relationships between the PF percentage and C-reactive protein (CRP) and homeostasis model assessment of insulin resistance (HOMA-IR) to clarify the gender discrepancy., Results: For cardiovascular mortality, the adjusted hazard ratios for WCMetS, PFMetS, and PF-combined definition MetS were 1.867, 1.742, and 2.117, respectively (all P < 0.001). A positive association between PF percentage and CRP in men and a negative correlation between PF percentage and HOMA-IR in women after adjustment for all variates were found., Conclusions: The PF-combined definition of MetS had a stronger predictive ability for all-cause and cardiovascular mortality than general MetS. Notably, the PF might have differential gender-specific health effects on cardiovascular events., (© 2018 John Wiley & Sons, Ltd.)

Metabolic disorders are prevalent worldwide and have recently become public health problems recently. Previous studies have proposed different body composition indices for predicting future cardiovascular risks. We hypothesized an association among fat-to-muscle ratio (FMR), metabolic syndrome (MetS), hypertension (HTN), prediabetes, type 2 diabetes mellitus (DM), and cardiovascular risk in an adult population. A total of 66829 eligible subjects composed of 34182 males and 32647 females aged 20 years or older were obtained from health examinations in the Tri-Service General Hospital from 2011 to 2017. The body composition indices included fat and muscle mass measured by bioelectrical impedance analysis. A multivariable regression model was performed in a large population-based cross-sectional study. FMR was significantly associated with MetS, prediabetes, DM and HTN in all models of both genders. Based on quartile analysis, higher FMR had higher predictive ability for adverse health outcomes. The association between different definitions of MetS and the Framingham risk score was analyzed, and FMR-incorporated MetS was more useful for predicting higher Framingham risk scores than traditional definitions. FMR was a useful indicator for the presence of adverse cardiometabolic risks. Compared to traditional definition of MetS, FMR-incorporated MetS had a greater ability to predict incident cardiovascular risks. FMR seemed to be a simple and effective index for the early prevention and management of cardiometabolic events., Competing Interests: The authors have declared that no competing interests exist.

Osteoporosis is one of the major complications in chronic hepatitis B virus (HBV) and hepatitis C (HCV) infection. However, few studies had examined the relationship between hepatic viral infection with bone loss. Our aim was to investigate the association between hepatic viral infection with bone mineral density (BMD) in a cross-sectional study. Participants who attended the health examinations at the Tri-Service General Hospital (TSGH), Taiwan, were enrolled in the study. Diagnosis of viral hepatitis was confirmed by the serum viral markers of hepatitis B surface antigen (HBsAg) and anti-HCV, and BMD measurement was performed by the bone densitometry. Subjects were divided into four groups by the presence of viral markers. The association between hepatic viral infection and BMD was examined by a multivariate linear regression model. HBV infection was inversely associated with BMD after full adjusting with β values of -0.17 (95% CI: -0.29, -0.05) (p < 0.05). The relationship remained significant in males (β = -0.16, 95% CI = -0.31, -0.01) (p < 0.05). In subjects with body mass index less than 30 HBV infection was associated with reduced BMD (β = -0.16, 95% CI = -0.29, -0.02) (p < 0.05). However, HCV infection was only associated with an increase in BMD in patients with BMI less than 30 (β = 0.17, 95% CI = 0.21, 0.32) (p < 0.05). Chronic HBV infection was significantly associated with reduced BMD in males. The impact of viral hepatitis on bone health deserves further investigation for the potential pathophysiological mechanisms.

Breast cancer is the most common cancer for women in Taiwan and post-lumpectomy radiotherapy is one of the therapeutic strategies for this malignancy. Although the 10-year overall survival of breast cancer patients is greatly improved by radiotherapy, the locoregional recurrence is around 10% and triple negative breast cancers (TNBCs) are at a high risk for relapse. The aim of this paper is to understand the mechanisms of radioresistance in breast cancers which may facilitate the development of new treatments in sensitizing breast cancer toward radiation therapy. Tribbles homolog 3 (TRIB3) is a pseudokinase protein and known to function as a protein scaffold within cells. It has been reported that higher TRIB3 expression is a poor prognostic factor in breast cancer patients with radiotherapy. In this study, we investigate the involvement of TRIB3 in the radiation response of TNBC cells. We first found that the expression of TRIB3 and the activation of Notch1, as well as Notch1 target genes, increased in two radioresistant TNBC cells. Knockdown of TRIB3 in radioresistant MDA-MB-231 TNBC cells decreased Notch1 activation, as well as the CD24-CD44⁺ cancer stem cell population, and sensitized cells toward radiation treatment. The inhibitory effects of TRIB3 knockdown in self-renewal or radioresistance could be reversed by forced expression of the Notch intracellular domain. We also observed an inhibition in cell growth and accumulated cells in the G₀/G¹ phase in radioresistant MDA-MB-231 cells after knockdown of TRIB3. With immunoprecipitation and mass spectrometry analysis, we found that, BCL2-associated transcription factor 1 (BCLAF1), BCL2 interacting protein 1 (BNIP1), or DEAD-box helicase 5 (DDX5) were the possible TRIB3 interacting proteins and immunoprecipitation data also confirmed that these proteins interacted with TRIB3 in radioresistant MDA-MB-231 cells. In conclusion, the expression of TRIB3 in radioresistant TNBC cells participated in Notch1 activation and targeted TRIB3 expression may be a strategy to sensitize TNBC cells toward radiation therapy., Competing Interests: The authors declare no conflict of interest.

An efficient and selective Cu catalyst for CO 2 electroreduction is highly desirable since current catalysts suffer from poor selectivity towards a series of products, such as alkenes, alcohols, and carboxylic acids. Here, we used copper(ii) paddle wheel cluster-based porphyrinic metal-organic framework (MOF) nanosheets for electrocatalytic CO 2 reduction and compared them with CuO, Cu 2 O, Cu, a porphyrin-Cu(ii) complex and a CuO/complex composite. Among them, the cathodized Cu-MOF nanosheets exhibit significant activity for formate production with a faradaic efficiency (FE) of 68.4% at a potential of -1.55 V versus Ag/Ag + . Moreover, the C-C coupling product acetate is generated from the same catalyst together with formate at a wide voltage range of -1.40 V to -1.65 V with the total liquid product FE from 38.8% to 85.2%. High selectivity and activity are closely related to the cathodized restructuring of Cu-MOF nanosheets. With the combination of X-ray diffraction, X-ray photoelectron spectroscopy, high resolution transmission electron microscopy and Fourier transform infrared spectroscopy, we find that Cu(ii) carboxylate nodes possibly change to CuO, Cu 2 O and Cu 4 O 3 , which significantly catalyze CO 2 to formate and acetate with synergistic enhancement from the porphyrin-Cu(ii) complex. This intriguing phenomenon provides a new opportunity for the rational design of high-performance Cu catalysts from pre-designed MOFs.

Aim: To assess the diagnostic value of the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) of diffusion tensor imaging (DTI) at several anatomical locations in patients with carpal tunnel syndrome (CTS) to explore the optimal parameters and measurement location., Materials and Methods: A search was conducted using the PubMed, EBSCO, Ovid, Web of Science, and Cochrane databases to identify articles relevant to this study published before September 2017. Studies were selected and included according to strict eligibility criteria. Mean differences (MD) and 95% confidence intervals (CIs) were used to compare FA and ADC values between CTS patients and healthy subjects. Potential publication bias was investigated., Results: Eleven studies involving 349 CTS wrists and 278 controls were selected for the meta-analysis. A notable MD: was found for lowered FA at the level of the pisiform bone for CTS versus controls (MD: -0.11, 95% confidence interval [CI]: -1.14 to -0.07, z=5.83, p<0.001). A higher ADC was found at the pisiform bone and hamate bone levels for CTS versus controls (P: MD: 0.15, 95% CI: 0.10 to 0.20, z=5.98, p<0.001, H: MD: 0.15; 95% CI: 0.09 to 0.21, z=4.67, p<0.001)., Conclusions: The meta-analysis demonstrated a significant FA reduction and ADC increase in CTS patients. This result supports the use of DTI parameters in differentiating CTS patients from health subjects. The anatomical site for FA at the pisiform and ADC at the pisiform and hamate levels were more accessible than other sites for the diagnosis of CTS patients., (Copyright © 2018 The Royal College of Radiologists.

The association between anthropometric indices with chronic kidney disease (CKD) was examined previously. However, the effect of body fat on renal function was not determined clearly. Our aim was to investigate the association of percent body fat (PBF) and renal function in adult population from health examination in Tri-Service General Hospital (2010-2016). 35087 participants aged 20 years and older were enrolled in the study. PBF was measured by bioelectrical impedance analysis (BIA). Estimation of renal function was performed by Taiwanese MDRD equation. Optimal cut-off values of PBF was accessed by a receiver-operator characteristic (ROC) curve analysis. Multivariate regression models were used in the relationship among changes of PBF, renal function, and future CKD. In terms of baseline PBF for CKD, optimal cut-off values of PBF in males and females were 21.55 and 40.75. The changes of PBF were more closely associated with renal function decline than waist circumference (WC) with β values of -0.173 (95% CI: -0.233, -0.112) and -0.077 (95% CI: -0.104, -0.049), respectively. After stratified by gender, this relationship remained significant in male population with β values of -0.276 (95% CI: -0.371, -0.181) and -0.159 (95% CI: -0.207, -0.112), respectively. Female subjects with increased baseline PBF over cut-off values had increased risk for predicting the future CKD with odd ratios (ORs) of 2.298 (95% CI: 1.006-5.252). Body fat had detrimental impact on renal function and development of CKD in adult population. Measurement of PBF for surveillance of renal function impairment was warranted.

Objective: To explore the prediction of aerobic exercise and resistance training on incidental metabolic syndrome (MetS) and diabetes in a Taiwanese cohort., Methods: The participant underwent annual health examinations and physical fitness tests, including 2-min push-up, 2-min sit-up, and endurance 3000-m none weight-bearing running exercise test from 2013 to 2015, were recruited. The cohort study involved 27,787 participants aged ≥20years in military services. Multivariate logistic regression odd ratios models were used to explore the associations between the performance of physical fitness and the development of MetS and diabetes., Results: The male participants without MetS at baseline with poor performance in aerobic and resistance exercise tests were likely to develop the MetS and diabetes two years later; while the female participants did not show the same results in statistical significance. Additionally, only poor performance measuring by resistance training exercise test was significantly associated with increased risk of metabolic components numbers at follow-up in all subjects without MetS (all P<0.05)., Conclusions: The poor performance in aerobic and resistance exercise tests might be predicting tools for MetS and diabetes in Taiwanese men without MetS at baseline. And resistance exercise displayed a substantial predicting ability in development of metabolic abnormality, MetS and diabetes in our study., (Copyright © 2018 Asia Oceania Association for the Study of Obesity.

Adverse systemic effect caused by betel nut had been reported for decades. Our aim was to determine whether betel nut had detrimental impact on the development of colorectal polyps in general population. Participants who attended health examinations at the Tri-Service General Hospital (TSGH) from 2010 to 2016 were included in the study. The habit of betel nut chewing was obtained from a self-reported questionnaire. Colorectal polyps were diagnosed by colonoscopies operated by experienced physicians. A logistic regression model was used for the association between betel nut chewing with the presence of colorectal polyps. After adjustment for pertinent information such as age, gender, biochemistry data and personal history, the odd ratios (ORs) of colorectal polyps among betel nut chewers was 1.49 (95%CI: 1.14-1.94). Besides, betel nut chewers in the higher percentage body fat (PBF) group had higher risk for developing colorectal polyps with ORs of 2.07 (95%CI:1.23-3.47). Subjects with habit of betel nut chewing were associated with an increased risk of colorectal polyps in Taiwanese general population. Screening for betel nut chewing history and encouraging cessation might offer improved quality of life. A further research for this association was warranted., Competing Interests: The authors have declared that no competing interests exist.

Family history was one of the major risk factors for developing adverse health outcomes such as metabolic syndrome (MetS), type 2 diabetes mellitus (DM) and hypertension (HTN). Our aim was to examine the relationship between different family histories and cardiometabolic events, including DM, stroke, myocardial infarction (MI), and HTN. Participants who attended the health examinations at the Tri-Service General Hospital from 2010 to 2016 were enrolled in the study and were categorized into four groups by representing different family history. A multivariable logistic regression model was used for the associations between various family history with the cardiometabolic events. Subjects with family history of DM were divided into quartiles by percentage body fat (PBF) to be analyzed for these adverse outcomes. In the cross-sectional analysis, subjects with family history of DM had significant association with MetS (OR = 1.34 [95%CI: 1.17-1.54]) and DM (OR = 3.03 [95%CI: 2.44-3.76]), and those with family history of HTN were positively associated with HTN (OR = 1.60 [95%CI: 1.41-1.81]). Notably, those with family history of DM in higher PBF quartiles had substantially increased association of cardiometabolic events (MetS: OR = 15.20 [95%CI: 9.87-23.39]; DM: OR = 3.35 [95%CI: 1.91-5.90]; HTN: 2.81 [95%CI: 1.84-4.29]). Individuals with family history of DM were positively associated with MetS and DM, and those with family history of HTN was associated with HTN. Family history assessment was requested especially in obese population for screening adverse health outcomes.

There are over 60 species within the freshwater fish genus Sinocyclocheilus (Cypriniformes: Cyprinidae) distributed throughout the Yunnan-Guizhou Plateau and its surrounding areas in China. In recent years, the increasing number of new species described has raised some controversy about the validity of several species within this genus, notably the putative sympatric species pair S. qiubeiensis and S. jiuchengensis. To test the validity of S. qiubeiensis and S. jiuchengensis, we analyzed the complete sequences of the mitochondrial cytochrome b (CYTB) gene of 20 identified species and one outgroup species. Phylogenetic relationships were reconstructed using CYTB with maximum likelihood (ML) and Bayesian inference (BI) methods. Our phylogenetic results showed that all individuals of S. qiubeiensis and S. jiuchengensis clustered in one clade with strong support. In addition, the genetic distance between the two species was 0.11%, within the range observed at the intraspecific level. The most recent common ancestor of S. qiubeiensis and S. jiuchengensis dated back to 0.13 million years ago, indicating little time for complete speciation to have occurred. These results clearly support the viewpoint that S. jiuchengensis is a synonym of S. qiubeiensis.

Accumulated evidence has suggested associations between glucose abnormalities and insulin resistance with hepatitis C virus (HCV) and hepatitis B virus (HBV) infections. However, few studies have reported the effect of hepatitis virus infections on body composition. Our aim was to explore the association of hepatitis virus infections with percent body fat (PBF) in a cross-sectional analysis. A total of 69226 subjects obtained from the health examinations at Tri-Service General Hospital (TSGH) from 2010 to 2016 were enrolled in the study. Participants were divided into subgroups based on the presence of hepatitis B surface antigen (HBsAg) and anti-HCV. PBF was measured by bioelectrical impedance analysis (BIA). A multivariable linear regression model was applied to test the association of hepatitis virus infections with PBF and glycemic status. In male participants, hepatitis virus infections were closely associated with increased PBF, especially in those subjects with HCV/HBV coinfection. HCV/HBV coinfection was positively correlated with fasting plasma glucose and postprandial glucose while HCV and HBV mono-infection were not. The impact of hepatitis virus infection on increased PBF was observed in general population with gender difference. A further study on the treatment of hepatitis virus infection might help prevent the development of obesity-related diseases., Competing Interests: The authors have declared that no competing interests exist.

Galaxamide is a rare cyclic homopentapeptide composed of three leucines and two N-methyl leucines isolated from marine algae Galaxaura filamentosa. The strong antitumor activity of this compound makes it a promising candidate for tumor therapy. The synthesis of galaxamide, however, is a complex process, and it has poor water solubility. On the basis of its special chemical composition, we designed a series of linear leucine homopeptides. Among seven dipeptide derivatives, five compounds with terminal protection groups and methyl substitution of the hydrogen in the amido group showed remarkable inhibitory effects against various cancer cells. N-tertbutyl-D-leucine-N-methyl-D-leucinebenzyl (A7), the only stereomer condensed by two D-leucines, showed the highest antineoplastic activity. A7-treated cells showed cell cycle arrest and morphological changes typical of cells undergoing apoptosis. The population of Annexin-V positive/propidium iodide-negative cells also increased, indicating the induction of early apoptosis. A7 promoted the cleavage of caspase-9 and caspase-3, as well as increased intracellular Ca levels and decreased the mitochondrial membrane potential. Collectively, certain linear leucine dipeptides derived from cyclic pentapeptide are able to inhibit tumor cell proliferation through cell cycle arrest and apoptosis induction. The N-methyl group in the side chain and the D/L conformation of the amino-acid residue are critical for their activity.

A growing amount of evidence suggests that thyroid-stimulating hormone (TSH) is associated with cardiometabolic risk. However, there have been few longitudinal studies. The aim of this study was to explore the causal relationship between TSH and metabolic syndrome (MetS) in a large population-based longitudinal study. From 2010 to 2016 at the Health Management Center at Tri-Service General Hospital, 25,121 eligible patients were enrolled in our cross-sectional analyses. Cox proportional hazard models were used to investigate the longitudinal association among hypertension (HTN), prediabetes (pre-DM), MetS, diabetes (DM) and TSH levels (N = 12,463). The average follow-up time was 7.2 years. In the cross-sectional analysis, the OR for MetS was 1.06 (95% CI = 1.03-1.09; P< 0.05), while the ORs for DM, pre-DM or HTN were not statistically significant (all P> 0.05). After dividing TSH levels into four quartiles, the ORs for the presence of MetS determined by comparing the highest TSH quartile with the lowest TSH quartile were 1.37 (95% CI = 1.18-1.60), 1.42 (95% CI = 1.20-1.67), and 1.44 (95% CI = 1.22-1.69) (all, P<0.05) in model 1, model 2 and model 3 respectively. The HR for the incidence of MetS was 1.33 (95% CI = 1.17-1.51; P < 0.05). Our study revealed that TSH levels had a strong association with incident MetS., Competing Interests: The authors have declared that no competing interests exist.

Fibrocystic breast change (FBC) is extremely common and occurrs in 90% of women during their lives. The association between body composition and risk of breast cancer is well established. We hypothesized that the effect might exist during the development of FBC. Our aim was to examine the relationships of total lean mass (TLM) and percent body fat (PBF) with FBC in a general female population. In total, 8477 female subjects aged 20 years or older were enrolled in the study at the Tri-Service General Hospital in Taiwan from 2011 to 2016. Comprehensive examinations including biochemical data, measurements of body composition and breast ultrasound were performed. PBF was positively associated with the presence of FBC (OR = 1.039, 95%CI: 1.018-1.060), and TLM showed the opposite result (OR = 0.893, 95%CI: 0.861-0.926). Condition of metabolic syndrome (MetS), diabetes (DM) and fatty liver modified the association between PBF and FBC (P < 0.001, P = 0.032 and P = 0.007, respectively). Female subjects diagnosed with MetS, DM, and fatty liver had higher risk of developing FBC than control subjects (OR = 1.110, 95%CI: 1.052-1.171; OR = 1.144, 95%CI: 1.024-1.278; OR = 1.049, 95%CI: 1.019, 1.080). Those with higher PBF (for highest quartile versus lowest, OR = 2.451, 95%CI: 1.523-3.944) or lower TLM (for highest quartile versus lowest, OR = 0.279, 95%CI: 0.171-0.455) had increased risk of developing FBC. In conclusion, increased PBF and reduced TLM were likely to predict the risk of the presence of FBC in a general female population.

Purpose: To compare the treatment efficacy of percutaneous catheter drainage alone to catheter drainage combined with ozone in the management of pyogenic liver abscess (PLA)., Material and Methods: This prospective study included 85 patients diagnosed with PLA. All patients were randomly divided into two groups: catheter drainage alone (Group I); catheter drainage combined with ozone (Group II). Drainage was considered successful when: 1) the abscess cavities were completely drained, and 2) clinical symptoms were resolved. Kruskall-Wallis nonparametric test was used to compare the success rates, length of stay (LOS), and need of further surgery. A value of p < 0.05 was considered significant for all statistical analyses., Results: In all the patients' percutaneous catheters were placed successfully under the guidance of computed tomography. All of the patients in Group I (43; 50.6%) were treated with percutaneous catheter drainage alone, while the patients in Group II (42; 49.4%) were treated with PCD combined with ozone. The success rates of Group I and II were 81% and 94%, respectively ( p < 0.05). The duration of fever as well as LOS was longer for Group I when compared with Group II ( p < 0.05)., Conclusions: Catheter drainage combined with ozone is an effective and safe treatment in PLA., Competing Interests: The authors report no conflict of interest.

Purposed: This study examined the associations between 25-hydroxyvitamin D [25(OH)D] and common anthropometric parameters., Methods: The data were derived from the National Health and Nutrition Examination Survey from 2001 through 2004. We divided all subjects into two groups with a cut-off point for body mass index set at 30. The primary outcome was the potential relationship between the anthropometric parameters and 25(OH)D status., Results: A positive association was found between the 25(OH)D levels and calf circumference (CC) in all of the designed models (P < 0.001). The adjusted β coefficient of the 25(OH)D levels for the CC was 0.542 (95% confidence intervals (CI), 0.376-0.708, P < 0.001) after adjusting for all covariates. An increasing linear tendency for 25(OH)D was present in non-obese participants. Additionally, subjects in the higher tertiles of CC tended to have higher 25(OH)D levels with a significant correlation (P for trend <0.001)., Conclusion: A positive association between 25(OH)D concentration and CC in non-obese individuals was observed., (Copyright © 2018 Elsevier B.V.

Organic agriculture has a higher potential than traditional agriculture to reduce environmental emissions. However, heavy metals in organic manure inevitably exacerbate eco-toxicity. At present, there are few studies on systematically and comprehensively evaluating the effects of different production modes on the environmental impact of vegetable production in the North China Plain (NCP). The objective of this study is to provide a theoretical direction for reducing the negative impact of greenhouse vegetable production. In this study, we used a greenhouse eggplant production (2013-2016) as case study and conducted a field experiment in Quzhou County, Hebei Province, China. The life cycle assessment (LCA) approach was used to analyze and compare the production and environmental impacts of eggplant production under three modes:conventional, integrated, and organic. The results showed that the potential for water contamination, eutrophication, and soil contamination was high among the three modes, ranging from 82.05% to 84.02%, 10.29% to 12.32%, and 2.62% to 3.48%, respectively. This is occurred mainly in the arable farming subsystem and is attributed to the loss of nitrogen (N) and phosphorus (P), pesticide residues, and heavy metals in organic manure. The environmental impact index of the integrated mode is the lowest, with a value of 0.596, which is 30.3% and 6.7% lower than those of the conventional and organic modes. The integrated mode significantly reduces the emission of pollutants from the greenhouse vegetable production in the arable farming subsystem; therefore, it is the best management practice. In the integrated mode, the environmental costs of producing one ton of eggplant are 46.6 J for energy depletion, 81.9 m 2 for land occupation, 0.0046 m 3 for water depletion, 0.0054 kg (CO 2 -eq) for global warming, 0.0060 kg (SO 2 -eq) for acidification, 0.0735 kg (PO 4 -eq) for aquatic eutrophication, 2.84E-05 kg (1,4-DCB-eq) for human toxicity, 0.4892 kg (1,4-DCB-eq) for aquatic eco-toxicity, and 0.0174 kg (1,4-DCB-eq) for soil eco-toxicity. Optimizing field management measures such as the application of biological pesticides, using high quality organic fertilizer, and improving the efficiency of N and P use, can better control the negative environmental impacts in the life cycle of vegetable production and improve environmental sustainability in the NCP.

Objective: This study was designed to compare the effects of catheter drainage alone and combined with ozone in the management of multiloculated pyogenic liver abscess (PLA)., Methods: The prospective study included 60 patients diagnosed with multiloculated PLA. All patients were randomly divided into two groups: catheter drainage alone (group I) and catheter drainage combined with ozone (group II). Drainage was considered successful when (1) the abscess cavity was drained and (2) clinical symptoms were resolved. Kruskal-Wallis nonparametric test was used to compare the success rates, length of stay (LOS), and need for further surgery of the two groups. P < 0.05 indicates significant difference., Results: All patients' catheters were successfully placed under CT guidance. Group I was treated with catheters alone and group II was treated with catheters and ozone. The success rates of groups I and II were 86% and 96%, respectively ( P < 0.05). And compared with group II, the duration of fever in group I was longer ( P < 0.05), and the LOS was also longer ( P < 0.05)., Conclusion: Catheter drainage combined with ozone is an effective and safe treatment in multiloculated PLA. The Clinical Registration Number is ChiCTR1800014865.

Background: A growing number of studies are available to shed some light on the association between uric acid (UA) and cardiovascular diseases. However, there have been few studies to support a causal link between UA, metabolic syndrome (MetS), diabetes mellitus (DM) and hypertension (HTN) in young subjects., Methods: From the Health Examination Registration System of Taiwanese military service during the period 2013-2015, there were 46,561 eligible participants who were 20years old or older in our study. Different analytical steps of analysis were performed to examine the association between UA and cardiometabolic risk using logistic regression, receiver operating characteristic (ROC) curve analysis and Cox regression., Results: For total population, serum UA had significant associations with the presence of MetS (OR=2.08, 95% CI=1.51-2.87), DM (OR=2.59, 95% CI=1.09-6.19) and HTN (OR=1.49, 95% CI=1.07-2.07) in the cross-sectional analysis. According to the cut-off values of UA calculating by the ROC curve analysis in each sex/age subgroup, the association between UA and incident adverse outcomes were analyzed in a longitudinal study. In male, higher UA significantly increased the risks for developing MetS in 30-40years (HR=1.12, 95% CI=1.01-1.25), DM in <30years (HR=2.75, 95% CI=1.38-5.45) and HTN in all subgroups (HR=1.17, 95% CI=1.01-1.37; HR=1.65, 95% CI=1.08-2.53; HR=1.72, 95% CI=1.22-2.43). In females, a higher UA was significantly associated with an increased risk of incident MetS in >40years (HR=2.99, 95% CI=1.34-6.64), HTN in >40years (HR=2.58, 95% CI=1.02-6.55), and no increased risk of DM., Conclusions: Our study concluded that serum UA is an important predictor for the risk of incident MetS, DM, and HTN in adults, especially in male population., (Copyright © 2017.

Context: Calf circumference (CC) was a useful anthropometric tool, but there was limited study on the effect of CC on metabolic syndrome (MetS) for cardiovascular risk., Objective: The objective of our study was to determine whether adding CC as a component of MetS refined correlating MetS with cardiovascular, all-cause, and cancer mortality risks., Design, Setting, Patients, and Interventions: From the National Health and Nutrition Examination Survey data set for 1999 through 2002, we analyzed four types of MetS: (1) increased waist circumference and two or more of four MetS components (WaistMetS); (2) decreased CC and two or more of four MetS components (CalfMetS); (3) increased waist-to-calf ratio and two or more of four MetS components (WCRMetS); and (4) decreased CC and three or more of five MetS components (CC+MetS)., Primary Outcome Measure: The cause-specific hazard ratios were measured as categorized by the four types of MetS., Results: For cardiovascular mortality, the adjusted hazard ratios for WaistMetS, CalfMetS, WCRMetS, and CC+MetS were 1.867, 1.871, 1.949, and 2.306, respectively (all P < 0.001). Notably, CalfMetS showed the strongest positive correlation with serum C-reactive protein levels, and WCRMetS had the strongest positive relationship with homeostasis model assessment of insulin resistance., Conclusions: Adding CC to the components of MetS correlated with higher cardiovascular and all-cause mortality risk than the traditional definition of MetS.

Emerging evidences addressed an association between phosphate and muscle function. Because little attention was focused on this issue, the objective of our study was to explore the relationship of phosphate with muscle strength, dynapenia, and sarcopenia. From the National Health and Nutrition Examination Survey, a total of 7421 participants aged 20 years or older were included in our study with comprehensive examinations included anthropometric parameters, strength of the quadriceps muscle, and appendicular lean masses. Within the normal range of serum phosphate, we used quartile-based analyses to determine the potential relationships of serum phosphate with dynapenia, and sarcopenia through multivariate regression models. After adjusting for the pertinent variables, an inverse association between the serum phosphate quartiles and muscle strength was observed and the linear association was stronger than other anthropometric parameters. Notably, the significant association between phosphate and muscle strength was existed in >65 years old age group, not in 20-65 years old. The higher quartiles of phosphate had higher likelihood for predicting the presence of dynapenia rather than sarcopenia in entire population. Our study highlighted that higher quartiles of phosphate had significant association with lower muscle strength and higher risks for predicting the presence of dynapenia.

This paper presents a simple yet effective supervised deep hash approach that constructs binary hash codes from labeled data for large-scale image search. We assume that the semantic labels are governed by several latent attributes with each attribute on or off, and classification relies on these attributes. Based on this assumption, our approach, dubbed supervised semantics-preserving deep hashing (SSDH), constructs hash functions as a latent layer in a deep network and the binary codes are learned by minimizing an objective function defined over classification error and other desirable hash codes properties. With this design, SSDH has a nice characteristic that classification and retrieval are unified in a single learning model. Moreover, SSDH performs joint learning of image representations, hash codes, and classification in a point-wised manner, and thus is scalable to large-scale datasets. SSDH is simple and can be realized by a slight enhancement of an existing deep architecture for classification; yet it is effective and outperforms other hashing approaches on several benchmarks and large datasets. Compared with state-of-the-art approaches, SSDH achieves higher retrieval accuracy, while the classification performance is not sacrificed.

Objective: To investigate the effects of 4-week moderate aerobic exercise plus diet control on serum levels of total insulin-like growth factor 1(IGF-1) and IGF-1 binding protein-3 (IGFBP-3) as well as IGF-1 activity (reflected by molar ratio of IGF-1/IGFBP-3) in female obese adolescents and youths, and their possible role on fat loss, and improvement of glucose and lipid metabolism., Methods: Nine female obese youths (age:18~19 y) and 30 female obese adolescents (age:14~16 y) were recruited and undertook 4-week aerobic exercise such as swimming and jogging (6 days/week, twice a day, 2 h/time with 5 min rest per 30 min exercise) with gradual increase of intensity from low (heart rate immediately post-exercise of 1st week:100~120 beats/min) to moderate (heart rate immediately post-exercise of 2 nd -4 th weeks:120~140 beats/min) level, combined with a diet intervention (total daily energy intake of 1 400 or 1 600 kcal according to basal metabolism rate) in Shanghai Dianfeng weight loss enclosed camp. Nine normal weight young women and 9 female children matched at age and nationality were recruited as the normal control. Before and after the experimental period, anthropometric index (body weight, body mass index(BMI) and waist circumference), glucose and lipid metabolism parameters including fasting blood glucose (FBG), fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR), triglyceride (TG); total cholesterol (TC), low density lipoprotein (LDL) and high density lipoprotein (HDL), and serum levels of total IGF-1 and IGFBP-3 were measured, and IGF-1 activity was calculated in the obese and normal control female adolescents., Results: ①Compared with normal control, the serum levels of total IGF-1 and IGFBP-3 were decreased in the female obese youths and adolescents, and IGF-1 activity was reduced only in the obese female adolescents. ②The serum level of IGFBP-3 was down-regulated and IGF-1 activity was up-regulated while no change of serum total IGF-1 was induced by 4-week moderate aerobic exercise plus diet control, accompanied with significant decreases of body weight, BMI and waist circumference as well as improvement of glucose and lipid metabolism in the female obese youths and adolescents. Except for a positive association between the increased IGF-1 activity and the decreased waist circumference was found in the female obese youths by Pearson's correlation analysis, there was no relation of the decreased IGFBP-3, the increased IGF-1 activity with the improvements of anthropometric index and glucose and lipid metabolism in female obese youths and adolescents., Conclusions: The serum level of IGFBP-3 was down-regulated and the IGF-1 activity was up-regulated by 4-week moderate aerobic exercise plus diet control in female obese youths and adolescents. The increase of IGF-1 activity might be associated with the exercise-plus-diet-induced decrease of waist circumstance in female obese youths.

Background: To assess the effect of aspiration in the biopsy-side down position to deal with delayed pneumothorax after computed tomography (CT)-guided lung biopsy., Methods: A retrospective review was performed of the 236 delayed pneumothorax patients who underwent CT-guided transthoracic needle biopsies (TTNBs). Asymptomatic minimal pneumothorax patients were managed conservatively. Manual aspirations were applied for symptomatic cases with minimal pneumothorax and all cases with moderate to large pneumothorax. Patients were included into two groups: in group A (35 patients), aspiration was performed in the same position as the biopsy, while in group B (54 patients), patients were turned to the biopsy-side down position (from supine to prone or vice versa), and aspiration was conducted. The efficacy of two approaches was evaluated., Results: One hundred forty-seven (62.3%) asymptomatic cases resolved without treatment. Distance between parietal and visceral pleura before and after aspiration were 4.24±1.87 and 1.93±2.33 cm for group A, 3.92±1.31 and 0.98±1.50 cm for group B, respectively. Volume of aspirated air in group A and group B were 735.4±231.8 and 434.8±320.3 mL, respectively. Complete lung expansion was detected in 28.6% (10/35) and 38.9% (21/54) for group A and group B, respectively. The overall effective rate and failure rate were 74.3% (26/35) and 25.7%(9/35) for group A, 92.6% (50/54) and 7.4%((4/54))for group B, respectively, which have significant statistic difference (P<0.05)., Conclusions: Manual aspiration in biopsy-side down position demonstrates the safety and efficacy in treating delayed pneumothorax after CT-guided TTNBs. Thus reduce the rate of pneumothorax requiring drainage catheter placement., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.
