High temperature stress disturbs cellular homoeostasis and results in a severe retardation in crop growth and development. Thus, it is important to reveal the mechanism of plants coping with heat stress. In this study, a novel gene that we identified from Brassica napus, referred to as Bn TR1, was found to play a key role in heat stress response in planta. Bn TR1 is a membrane-bound RINGv ( C4HC3) protein that displays E3 ligase activity in vitro. We demonstrated that modest expression of Bn TR1 is sufficient to minimize adverse environmental influence and confers thermal resistance on development without any detrimental effects in B. napus and Oryza sativa. Our investigation into the action mechanism indicates that Bn TR1 is likely to be involved in mediating Ca2+ dynamics by regulating the activity of calcium channels, which further alters the transcripts of heat shock factors and heat shock proteins contributing to plant thermotolerance. Hence, our study identified Bn TR1 as a novel key factor underlying a conserved mechanism conferring thermal resistance in plants. [ABSTRACT FROM AUTHOR]

We generalize the concept of well-posedness by perturbations for optimization problem to a class of variational-hemivariational inequalities. We establish some metric characterizations of the well-posedness by perturbations for the variational-hemivariational inequality and prove their equivalence between the well-posedness by perturbations for the variational-hemivariational inequality and the well-posedness by perturbations for the corresponding inclusion problem.

The pH-induced demulsification behaviors of “on-off” oil-in-water emulsions using cetyltrimethylammonium bromide (CTAB) and potassium phthalic acid (PPA) mixtures as emulsifiers were investigated by coarse-grained (CG) molecular dynamics (MD) simulations and experiments, aiming to design a new pH-responsive emulsion. On the one hand, we simulated the stability of emulsions of n -octane and aqueous CTAB/PPA solution, and phase diagrams of emulsion with different CTAB/PPA contents were observed at different pH. Furthermore, the demulsification processes from the low pH to high pH was investagated and clearly it began with film rupture and then accomplished with droplets fusion in few nanoseconds. Via analyzing the structure and molecular arrangment of the emulsion droplets, it was found that the reasons on pH-induced demulsification were weak hindrance effect of the surfactant film and electrostatic repulsion among emulsion droplets at high pH. On the other hand, through our experiments, the differences on stability of emulsions were verified and the reversible emulsification and demulsification processes by changing pH values were observed, which agreed well with our simulations. This work designed a new kind of pH-responsive emulsion using commercial surfactants CTAB/PPA by simulations and verified its pH-induced demulsification by experiments. It sets up a bridge between CG MD approach and experiment, which is expected to trigger further understanding and studies on stimuli responsive emulsion systems. [ABSTRACT FROM AUTHOR]

The nonhomogeneous grey model (NGM) is a novel tool for time series forecasting, which has attracted considerable interest of research. However, the existing nonhomogeneous grey models may be inefficient to predict the complex nonlinear time series sometimes due to the linearity of the differential or difference equations based on which these models are developed. In order to enhance the accuracy and applicability of the NGM model, the kernel method in the statistical learning theory has been utilized to build a novel kernel regularized nonhomogeneous grey model, which is abbreviated as the KRNGM model. The KRNGM model is represented by a differential equation which contains a nonlinear function of t . By constructing the regularized problem and using the kernel function which satisfies the Mercer’s condition, the parameters estimation of KRNGM model only involves in solving a set of linear equations, and the nonlinear function in the KRNGM model can be expressed as a linear combination of the Lagrangian multipliers and the selected kernel function, and then the KRNGM model can be solved numerically. Two case studies of petroleum production forecasting are carried to illustrate the effectiveness of the KRNGM model, comparing to the existing nonhomogeneous models. The results show that the KRNGM model outperforms the existing NGM, ONGM, NDGM model significantly. [ABSTRACT FROM AUTHOR]

The phytohormone abscisic acid (ABA) plays an important role in the ability of plants to cope with drought stress. As core members of the ABA signaling pathway, protein phosphatase type 2Cs (PP2Cs) have been reported in many species. However, the functions of MdPP2Cs in apple (Malus domestica) are unclear. In this study, we identified two PP2C-encoding genes, MdPP2C24/37, with conserved PP2C catalytic domains, using sequence alignment. The nucleus-located MdPP2C24/37 genes were induced by ABA or mannitol in apple. Genetic analysis revealed that overexpression of MdPP2C24/37 in Arabidopsis thaliana led to plant insensitivity to ABA or mannitol treatment, in terms of inhibiting seed germination and overall seedling establishment. The expression of stress marker genes was upregulated in MdPP2C24/37 transgenic lines. At the same time, MdPP2C24/37 transgenic lines displayed inhibited ABA-mediated stomatal closure, which led to higher water loss rates. Moreover, when exposed to drought stress, chlorophyll levels decreased and MDA and H2O2 levels accumulated in the MdPP2C24/37 transgenic lines. Further, MdPP2C24/37 interacted with MdPYL2/12 in vitro and vivo. The results indicate that MdPP2C24/37 act as negative regulators in response to ABA-mediated drought resistance.

Introduction: Background: exercise can increase the species and quantity of beneficial gut microbiota, enrich the diversity of microflora, and promote the development of symbiotic bacteria, especially in the stage of ontogeny. However, there is little evidence of the short-term voluntary exercise effect on the gut microbiota in developing mice. Material and method: therefore, we used short-term voluntary wheel running model to study the gut microbiota of developing mice (1 month old), and detected the fecal samples by 16S rRNA gene sequencing. Results: the results showed that after 4 weeks of voluntary wheel running, the body weight of the running group was significantly lower than that of the control group. Conclusion: there was a significant separation between the running group and the control group in beta diversity measures. At the family level, the clostridiales flora of the running group was higher than that of the control group. Compared with the control group, the abundance of parabacteroides flora and anaerovorax flora increased significantly, and the abundance of anaerotruncus flora and odoribacter flora decreased significantly in the running group. These results showed that gut microbiota be affected after short-term voluntary wheel running in developing mice. [ABSTRACT FROM AUTHOR]- Published

LABELS , *TASK analysis - Abstract
Complex objects are usually with multiple labels, and can be represented by multiple modal representations, e.g., the complex articles contain text and image information as well as multiple annotations. Previous methods assume that the homogeneous multi-modal data are consistent, while in real applications, the raw data are disordered, e.g., the article constitutes with variable number of inconsistent text and image instances. Therefore, Multi-modal Multi-instance Multi-label (M3) learning provides a framework for handling such task and has exhibited excellent performance. However, M3 learning is facing two main challenges: 1) how to effectively utilize label correlation and 2) how to take advantage of multi-modal learning to process unlabeled instances. To solve these problems, we first propose a novel Multi-modal Multi-instance Multi-label Deep Network (M3DN), which considers M3 learning in an end-to-end multi-modal deep network and utilizes consistency principle among different modal bag-level predictions. Based on the M3DN, we learn the latent ground label metric with the optimal transport. Moreover, we introduce the extrinsic unlabeled multi-modal multi-instance data, and propose the M3DNS, which considers the instance-level auto-encoder for single modality and modified bag-level optimal transport to strengthen the consistency among modalities. Thereby M3DNS can better predict label and exploit label correlation simultaneously. Experiments on benchmark datasets and real world WKG Game-Hub dataset validate the effectiveness of the proposed methods. [ABSTRACT FROM AUTHOR]

Background: Drug transporters and drug-metabolizing enzymes have been linked to drug-induced hepatotoxicity. Solute carrier organic anion transporter family member 1B1 ( SLCO1B1), cytochrome P450 2E1 ( CYP2E1), and UDP glucuronosyltransferase 1A1 ( UGT1A1) were selected as candidate genes to explore their association with susceptibility to anti-tuberculosis drug-induced hepatotoxicity (ATDH). Methods: Thirty-four tag single nucleotide polymorphisms (tagSNPs) in SLCO1B1, CYP2E1, and UGT1A1 with 10-kb expansion up- and down-stream were genotyped in 461 patients with ATDH and 466 patients without ATDH in a prospective 1:1 matched case-control study. The frequencies and distributions of genotypes and haplotypes were compared between the groups using three genetic models (dominant, recessive, and additive) to identify associations with susceptibility to ATDH. Results: Patients with the rs4149034 G/A, rs1564370 G/C, and rs2900478 T/A genotypes of SLCO1B1 had a significantly lower risk of ATDH, while those carrying the rs2417957 T/T and rs4149063 T/T genotypes had an increased risk. The rs4148323 A/A genotype of UGT1A1 was found to significantly reduce the risk of ATDH. Haplotype analysis showed the TGTG, TTTC, and GTTC haplotypes of SLCO1B1 were associated with an increased ATDH risk, whereas the GACC haplotype was related to a reduced risk. The ATG haplotype of UGT1A1 reduced the risk of ATDH. Moreover, treatment outcomes in tuberculosis patients were further affected by genetic variants of SLCO1B1. Conclusions: Genetic polymorphisms of SLCO1B1 and UGT1A1 were found to be associated with susceptibility to ATDH. Molecular identification of susceptibility genes provides a theoretical foundation for predicting the likelihood of ATDH and predicting treatment outcomes in tuberculosis patients.

The physicochemical, structural and functional properties of citric-acid-deamidated wheat gluten at controlled degrees of deamidation (25%, 40% and 55%), which were obtained by using different acid concentrations (3.93 × 10 −5 , 3.14 × 10 −3 and 2.36 × 10 −2 mol/L) and temperatures (70 °C 2 h, 90 °C 1 h and 110 °C 40 min), were compared. Various deamidation processing conditions leading to the same degree of deamidation resulted in proteins with different physicochemical and structural characteristics, as indicted by the degree of hydrolysis, Z-potential, surface hydrophobicity, particle size, SDS-PAGE results, SEC-HPLC results, intrinsic fluorescence and FTIR spectra. Agglomerative hierarchical clustering analysis and principal component analysis qualitatively indicated a significant effect of pH on protein deamidation. Three samples at 40% deamidation, which were produced by a moderate acid concentration, showed the best emulsifying and foaming properties. Processes conducted at greater than 90 °C causing protein aggregation and at a high acid concentration rupturing peptide bonds, impaired protein quality. These findings demonstrated that a limited amount of H + could function well in the catalysis of the deamidation of amide groups without an excess of H + , which hydrolyses peptide bonds in a stronger hydrothermal treatment.

Cement stabilization is used extensively to remediate soils contaminated with heavy metals. However, previous studies suggest that the elevated zinc (Zn) and lead (Pb) concentrations in the contaminated soils would substantially retard the cement hydration, leading to the deterioration of the performance of cement stabilized soils. This study presents a new binder, KMP, composed of oxalic acid-activated phosphate rock, monopotassium phosphate and reactive magnesia. The effectiveness of stabilization using this binder is investigated on soils spiked with Zn and Pb, individually and together. Several series of tests are conducted including toxicity characteristic leaching (TCLP), ecotoxicity in terms of luminescent bacteria test and unconfined compressive strength. The leachability of a field Zn- and Pb- contaminated soil stabilized with KMP is also evaluated by TCLP leaching test. The results show that the leached Zn concentrations are lower than the China MEP regulatory limit except when Zn and Pb coexist and for the curing time of 7 days. On the other hand, the leached Pb concentrations for stabilized soils with Pb alone or mixed Zn and Pb contamination are much lower than the China MEP or USEPA regulatory limit, irrespective of the curing time. The luminescent bacteria test results show that the toxicity of the stabilized soils has been reduced considerably and is classified as slightly toxic class. The unconfined compressive strength of the soils decrease with the increase in the Zn concentration. The stabilized soils with mixed Zn and Pb contaminants exhibit notably higher leached Zn concentration, while there is lower unconfined compressive strength relative to the soils when contaminated with Zn alone. The X-ray diffraction and scanning electron microscope analyses reveal the presence of bobierrite (Mg3(PO4) 2·8H2O) and K-struvite (MgKPO4·6H2O) as the main products formed in the KMP stabilized uncontaminated soils; the formation of hopeite (Zn3(PO4) 2·4H2O), scholzite (CaZn2(PO4) 2·2H2O), zinc hydroxide (Zn(OH)2), and fluoropyromorphite (Pb5(PO4)3F) in the soils are the main mechanisms for immobilization of Zn and Pb with the KMP binder. The change in the relative quantities of the formed phosphate-based products, with respect to the Zn concentration and presence of mixed Zn and Pb contaminants, can well explain the measured impact of the Zn concentration levels and presence of both Zn and Pb contaminants on the unconfined compressive strength of the KMP stabilized soils.

Abstract: This paper presents an investigation of the influence of zinc concentration, cement content, and curing time on the strength characteristics of cement treated zinc-contaminated soils. Zinc-contaminated soil is artificially prepared by mixing concentrated zinc nitrate solution with a high-plasticity clay. The zinc concentrations are 0, 0.01, 0.02, 0.05, 0.1, and 0.2%. The contaminated soils are then solidified with cement, of which the contents are 12, 15, and 18%. Both zinc concentration and cement content are based on the oven-dried soil weight. A series of unconfined compression tests are performed at curing times of 7, 28, 56, and 90d. The results reveal that the zinc concentration levels have significant influence on the brittleness/ductileness, unconfined compressive strength, strain at failure, and secant modulus of the soils. The relationships between the unconfined compressive strength and strain at failure/secant modulus are quantified. A simplified method is proposed for predicting the unconfined compressive strength of the cement treated zinc-contaminated soils. A comparison of the measured and predicted strength shows that the proposed method has a high accuracy. [Copyright &y& Elsevier]

- Abstract
Objective: To investigate the effects and mechanisms of olfactory three-needle (OTN) electroacupuncture (EA) stimulation of the olfactory system on cognitive dysfunction, synaptic plasticity, and the gut microbiota in senescence-accelerated mouse prone 8 (SAMP8) mice., Methods: Thirty-six SAMP8 mice were randomly divided into the SAMP8 (P8), SAMP8+OTN (P8-OT), and SAMP8+nerve transection+OTN (P8-N-OT) groups according to a random number table (n=12 per group), and 12 accelerated senescence-resistant (SAMR1) mice were used as the control (R1) group. EA was performed at the Yintang (GV 29) and bilateral Yingxiang (LI 20) acupoints of SAMP8 mice for 4 weeks. The Morris water maze test, transmission electron microscopy, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining, Nissl staining, Golgi staining, Western blot, and 16S rRNA sequencing were performed, respectively., Results: Compared with the P8 group, OTN improved the cognitive behavior of SAMP8 mice, inhibited neuronal apoptosis, increased neuronal activity, and attenuated hippocampal synaptic dysfunction (P<0.05 or P<0.01). Moreover, the expression levels of synaptic plasticity-related proteins N-methyl-D-aspartate receptor 1 (NMDAR1), NMDAR2B, synaptophysin (SYN), and postsynaptic density protein-95 (PSD95) in hippocampus were increased by OTN treatment (P<0.05 or P<0.01). Furthermore, OTN greatly enhanced the brain-derived neurotrophic factor (BDNF)/cAMP-response element binding (CREB) signaling and phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) signaling compared with the P8 group (P<0.05 or P<0.01). However, the neuroprotective effect of OTN was attenuated by olfactory nerve truncation. Compared with the P8 group, OTN had a very limited effect on the fecal microbial structure and composition of SAMP8 mice, while specifically increased the genera Oscillospira and Sutterella (P<0.05). Interestingly, the P8-N-OT group showed an abnormal fecal microbiota with higher microbial α-diversity, Firmicutes/Bacteroidetes ratio and pathogenic bacteria (P<0.05 or P<0.01)., Conclusions: OTN improved cognitive deficits and hippocampal synaptic plasticity by stimulating the olfactory nerve and activating the BDNF/CREB and PI3K/AKT/mTOR signaling pathways. Although the gut microbiota was not the main therapeutic target of OTN for Alzheimer's disease, the olfactory nerve was essential to maintain the homeostasis of gut microbiota., (© 2023.

- Abstract
Background: Despite the World Health Organisation certifying China malaria-free in 2021, the risk of local transmission caused by imported malaria cases remains a significant clinical and public health issue. It is necessary to present the changing trends of malaria in China and discuss the role of travel medicine services in consolidating malaria elimination., Methods: This study systematically reviewed articles and reports related to human malaria from 2013 to 2022 published in international and Chinese databases. Data on malaria (i.e. number of cases, Plasmodium spp., diagnostic method, country of acquisition, provinces with high risk of re-introduction and transmission) were collected and synthesised, then summarised using descriptive statistics., Results: Overall, 24 758 cases of malaria (>99.5% laboratory confirmed, > 99.2% imported, 0.5% fatal) were reported in China from 2013 to 2022, with a downward trend over the years (4128 cases in 2013 compared to 843 cases in 2022; χ2 trend p-value = 0.005). The last locally acquired case was reported in 2017. P. falciparum (65.5%) was the most common species identified, followed by P. vivax (20.9%) and P. ovale (10.0%). Two Pheidole knowlesi cases were also identified in 2014 and 2017 in returned travellers from Malaysia and Indonesia, respectively. The most common countries of malaria acquisition were Ghana, Angola, and Myanmar. P. vivax was mainly detected in returned travellers from Myanmar, while P. falciparum and P. ovale were detected in travellers from Sub-Saharan Africa. Imported cases were mainly reported in Yunnan, Jiangsu, Sichuan, Guangxi, Shandong, Zhejiang, and Henan provinces, where large numbers of Chinese people travel overseas for work., Conclusion: Returned travellers from malaria-endemic countries pose a significant risk of malaria re-introduction to China. Travel medicine should be strengthened to improve the capacity and accessibility of both pre- and post-travel services, including malaria prophylaxis and prompt diagnosis of illness in returned travellers., (© The Author(s) 2024.

- Abstract
Objectives: To observe the effect of electroacupuncture (EA) on behavior, oxidative stress factors in colon and substantia nigra of Parkinson's disease (PD) mice, so as to explore the mechanism of EA in treating PD., Methods: C57BL/6 mice were randomly divided into blank, model and EA groups, with 12 mice in each group. The PD mouse model was established by continuous gavage of rotenone for 4 weeks. Mice in the EA group received EA (2 Hz/15 Hz) at "Baihui" (GV20), "Quchi" (LI11) and "Zusanli" (ST36) for 20 min, 5 days a week for 2 weeks. After intervention, gait analysis was used to evaluate the motor ability and motor coordination. Ink propulsion rate was used to evaluate the intestinal transport function. The level of reactive oxygen species (ROS) in the colon was detected by flow cytometry. The contents of total protein (TP), malondialdehyde (MDA) and activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) in colon and substantia nigra were detected by ELISA. The expression of nuclear factor E2-related factor 2 (Nrf2) in substantia nigra was detected by immunofluorescence staining., Results: Compared with the blank group, the average speed, step rate, normal step ratio, distance between the front and hind feet, stride length, swing speed and maximum intensity of the maximum contact area of mice in the model group were decreased ( P <0.000 1, P <0.01, P <0.001), the maximum change rate of gait was increased ( P <0.001) in the model group. The intestinal propulsion rate, the activities of GSH-Px and SOD in the colon and substantia nigra, and the positive expression of Nrf2 in substantia nigra were decreased ( P <0.000 1, P <0.01, P <0.05), while the fluorescence intensity of ROS in the colon, the contents of MDA in colon and substantia nigra were increased ( P <0.01). Compared with the model group, the average speed, step rate, normal step ratio, distance between the front and hind feet, stride length, swing speed, and maximum intensity of the maximum contact area of the mice in the EA group were increased ( P <0.01, P <0.05, P <0.001, P <0.000 1), the maximum change rate of gait was decreased ( P <0.01). The intestinal propulsion rate, the activities of GSH-Px and SOD in the colon and substantia nigra, the positive expression of Nrf2 in substantia nigra were increased ( P <0.001, P <0.05, P <0.000 1), while the ROS fluorescence intensity in the colon, the MDA contents in the colon and substantia nigra were decreased ( P <0.01)., Conclusions: EA can improve the movement disorder, gait disorder and intestinal motor function of PD mice, and protect dopaminergic neurons from damage, which may be related to its effect in antagonistic brain-gut oxidative stress.

- Abstract
Objectives: To observe the effect of electroacupuncture (EA) on ferroptosis and apoptosis-related proteins in the substantia nigra of midbrain in mice with Parkinson's disease (PD), so as to explore its possible mechanisms in the treatment of PD., Methods: Twenty-four C57BL/6 mice were randomly divided into blank, model and EA groups, with 8 mice in each group. The PD model was established by continuous gavage of rotenone for 4 weeks. EA was applied at "Baihui" (GV20), "Quchi" (LI11) and "Zusanli" (ST36) for 20 min, once a day for 14 days, with 2-day rest after every 5-day treatment. The open field test was used to evaluate the residence time in the central area, ave-rage movement speed, and total distance of the open field. Western blot was used to detect the protein expression le-vels of divalent metal ion transporter 1 (DMT1), membrane ferroportin 1 (FPN1), glutathione peroxidase 4 (GPX4), proapoptotic protein Bax, and anti apoptotic protein Bcl-2 in the substantia nigra. Immunohistochemical method was used to detect the morphological changes of neurons and the positive expression of tyrosine hydroxylase (TH) in the substantia nigra of mice., Results: After 4 weeks of modeling, compared with the blank group, the residence time in the central area, average speed and total distance of open field were significantly lower ( P< 0.000 1, P< 0.01, P< 0.001);the protein expression levels of DMT1 and Bax in the substantia nigra were increased ( P <0.001, P <0.000 1), while the protein expression levels of FPN1, GPX4 and Bcl-2, and the optical density of TH
+ cells in the substantia nigra were decreased ( P <0.000 1, P <0.001) in the model group. In comparison with the model group, the residence time in the central area, average speed, and total distance of the EA group were increased ( P <0.01, P <0.05);the protein expression levels of DMT1 and Bax in the substantia nigra were decreased ( P <0.01, P <0.001), while the protein expression levels of FPN1, GPX4, and Bcl-2, and the optical density of TH+ cells in the substantia nigra were increased ( P <0.000 1, P <0.01, P <0.001, P <0.05)., Conclusions: EA has a protective effect on dopaminergic neurons in the substantia nigra of midbrain in PD model mice, which may be related with its effect in regulating oxidative stress and cell apoptosis induced by ferroptosis.- Published

- Abstract
Background: The MeltPro TB assay (MeltPro) is a molecular rapid diagnostic test designed for detecting resistance to antituberculosis drugs. However, the performance of MeltPro as an initial diagnostic test for simultaneously detecting the presence of Mycobacterium tuberculosis (MTB) and drug resistance has not been evaluated. This study aims to assess the performance of MeltPro as initial diagnostic test for simultaneous detection of MTB and drug resistance in clinical samples from patients with presumptive pulmonary tuberculosis (PTB)., Methods: A retrospective analysis was conducted on 1283 patients with presumptive PTB from two clinical centers, out of which 875 were diagnosed with PTB. The diagnostic accuracy of MeltPro, Xpert MTB/RIF (Xpert), and MGIT 960 for PTB detection was evaluated. Rifampicin (RIF), isoniazid (INH), ethambutol (EMB), streptomycin (STR), and fluoroquinolone (FQ) resistance were detected using MeltPro, with Xpert and/or the broth microdilution plate method (MYCOTB) results as references., Results: For the diagnosis of PTB, MeltPro showed a sensitivity of 69.0%, which was similar to Xpert (72.7%; P > 0.05) and higher than MGIT (58.1%; P < 0.001). The specificity of MeltPro was 97.1%, similar to Xpert (98.0%; P > 0.05). In smear-negative patients, MeltPro's sensitivity was 50.9%, similar to Xpert (56.5%; P > 0.05), and higher than MGIT (33.1%; P < 0.001). Based on Xpert and/or MYCOTB results, MeltPro exhibited a sensitivity and specificity of 98.3% and 99.2%, respectively, for detecting RIF resistance. Based on MYCOTB results, MeltPro's sensitivity for detecting resistance to INH, EMB, STR, and FQ was 96.4%, 89.1%, 97.5%, and 90.3%, respectively, with specificities of 96.0%, 96.0%, 95.2%, and 99.4%, respectively., Conclusion: The MeltPro TB assay could potentially be an effective alternative as the initial test for rapid diagnosis of PTB with drug-resistance detection in clinical practice., (© 2023.

- Abstract
Objective: To investigate the molecular mechanisms underlying the beneficial effect of electroacupuncture (EA) in experimental models of Alzheimer's disease (AD) in vivo., Methods: Senescence-accelerated mouse prone 8 (SAMP8) mice were used as AD models and received EA at Yingxiang (LI 20, bilateral) and Yintang (GV 29) points for 20 days. For certain experiments, SAMP8 mice were injected intravenously with human fibrin (2 mg). The Morris water maze test was used to assess cognitive and memory abilities. The changes of tight junctions of blood-brain barrier (BBB) in mice were observed by transmission electron microscope. The expressions of fibrin, amyloid- β (Aβ), and ionized calcium-binding adapter molecule 1 (IBa-1) in mouse hippocampus (CA1/CA3) were detected by reverse transcription-quantitative polymerase chain reaction (qRT-PCR), Western blot or immunohistochemical staining. The expression of fibrin in mouse plasma was detected by enzyme-linked immunosorbent assay. The expressions of tight junction proteins zonula occludens-1 and claudin-5 in hippocampus were detected by qRT-PCR and immunofluorescence staining. Apoptosis of hippocampal neurons was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining., Results: Fibrin was time-dependently deposited in the hippocampus of SAMP8 mice and this was inhibited by EA treatment (P<0.05 or P<0.01). Furthermore, EA treatment suppressed the accumulation of Aβ in the hippocampus of SAMP8 mice (P<0.01), which was reversed by fibrin injection (P<0.05 or P<0.01). EA improved SAMP8 mice cognitive impairment and BBB permeability (P<0.05 or P<0.01). Moreover, EA decreased reactive oxygen species levels and neuroinflammation in the hippocampus of SAMP8 mice, which was reversed by fibrin injection (P<0.05 or P<0.01). Mechanistically, EA inhibited the promoting effect of fibrin on the high mobility group box protein 1 (HMGB1)/toll-like receptor 4 (TLR4) and receptor for advanced glycation end products (RAGE)/nicotinamide adenine dinucleotide phosphate (NADPH) signaling pathways (P<0.01)., Conclusion: EA may potentially improve cognitive impairment in AD via inhibition of fibrin/A β deposition and deactivation of the HMGB1/TLR4 and RAGE/NADPH signaling pathways., (© 2023.

- Abstract
Objective: To observe the effect of early electroacupuncture(EA) intervention on ionized calcium binding adapter molecule 1 (Iba-1), tyrosine hydroxylase (TH) and tumor necrosis factor-α (TNF-α) in Parkinson's disease (PD) mice, so as to explore its neuroinflammation mechanism in treating PD., Methods: A total of 24 male C57BL/6J mice (9 weeks old) were randomly divided into control, model and EA groups, with 8 mice in each group. The PD model was established by long-term low dose subcutaneous injection of rotenone. Started at the same time with modeling, EA (2 Hz/100 Hz, 1 mA) was applied to "Shenting"(GV24), bilateral "Tianshu"(LI11), "Quchi"(ST25), and "Shangjuxu"(ST37) for 15 min, once a day for 8 weeks. The motor function was assessed by rotorod test and step length test. The expression levels of Iba-1 and TH proteins in substantia nigra pars compacta (SNpc) was detected by Western blot and immunohistochemistry. The expression level of TNF-α protein in colon tissue was examined by Western blot and immunofluorescence staining., Results: Compared with the control group, the fall latency shortened at 4, 6, and 8 weeks after modeling ( P <0.01) and the step length of hind limbs shortened at 5 and 7 weeks after modeling ( P <0.01), the expression levels of Iba-1 in SNpc and TNF-α in colon tissue were increased ( P <0.01), and the expression level of TH in SNpc was decreased ( P <0.01) in the model group. Compared with the model group, the fall latency prolonged at 6 and 8 weeks after modeling ( P <0.01) and the step length of hind limbs prolonged at 5 and 7 weeks after modeling ( P <0.01), the expression levels of Iba-1 in SNpc and TNF-α in colon tissue were decreased ( P <0.01, P <0.05), and the expression level of TH in SNpc was increased ( P <0.05, P <0.01) in the EA group., Conclusion: Early EA intervention can delay the occurring time of motor disfunction, alleviated the loss of substantia nigra dopaminergic neurons, and exerted a good neuroprotective effect on the degenerative changes in rotenone-induced PD mice, which may be related to its effects in alleviating the intestinal inflammation, inhibiting the activation of microglia, thereby reducing the neuroinflammation.

- Abstract
Chinese chive ( Allium tuberosum Rottler) is a popular food from Allium species in East and Southeast Asia. Most Allium species possess characteristic aromas and have antimicrobial activity. In this study, the antimicrobial activities of root, leaf, and scape extracts of Chinese chive at different pH levels (3.0, 5.0, 7.0, 9.0, and 10.7) were compared. The most pronounced activity was produced by the scape extract, and the greatest activity was obtained at pH 5.0. HPLC and GC-MS analysis showed that the major active ingredient was 2-amino-5-methylbenzoic acid. The mechanism of action of Chinese chive scape extracts may involve the depression or disruption of cell membrane integrity, according to our results of the leakage of electrolytes and protein, as well as scanning electron microscopy and transmission electron microscopy observations., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Chen, Cai, Ren, Xu, Liu, Zhao, Chen and Liu.)

- Abstract
Introduction: Background: exercise can increase the species and quantity of beneficial gut microbiota, enrich the diversity of microflora, and promote the development of symbiotic bacteria, especially in the stage of ontogeny. However, there is little evidence of the short-term voluntary exercise effect on the gut microbiota in developing mice. Material and method: therefore, we used short-term voluntary wheel running model to study the gut microbiota of developing mice (1 month old), and detected the fecal samples by 16S rRNA gene sequencing. Results: the results showed that after 4 weeks of voluntary wheel running, the body weight of the running group was significantly lower than that of the control group. Conclusion: there was a significant separation between the running group and the control group in beta diversity measures. At the family level, the clostridiales flora of the running group was higher than that of the control group. Compared with the control group, the abundance of parabacteroides flora and anaerovorax flora increased significantly, and the abundance of anaerotruncus flora and odoribacter flora decreased significantly in the running group. These results showed that gut microbiota be affected after short-term voluntary wheel running in developing mice.

- Abstract
Kiwifruit ( Actinidia ) is becoming increasingly popular worldwide due to its favorable flavour and high vitamin C content. However, quality parameters vary among cultivars. To determine the differences in quality and metabolic parameters of kiwifruit, we monitored the growth processes of 'Kuilv' ( Actinidia arguta ), 'Hongyang' ( Actinidia chinensis ) and 'Hayward' ( Actinidia deliciosa ). We found that 'Kuilv' required the shortest time for fruit development, while 'Hayward' needed the longest time to mature. The fruit size of 'Hayward' was the largest and that of 'Kuilv' was the smallest. Furthermore, 'Hongyang' showed a double-S shape of dry matter accumulation, whereas 'Kuilv' and 'Hayward' showed a linear or single-S shape pattern of dry matter accumulation during development. The three cultivars demonstrated the same trend for total soluble solids accumulation, which did not rise rapidly until 90-120 days after anthesis. However, the accumulation of organic acids and soluble sugars varied among the cultivars. During later fruit development, the content of glucose, fructose and quinic acid in 'Kuilv' fruit was far lower than that in 'Hongyang' and 'Hayward'. On the contrary, 'Kuilv' had the highest sucrose content among the three cultivars. At maturity, the antioxidative enzymatic systems were significantly different among the three kiwifruit cultivars. 'Hongyang' showed higher activities of superoxide dismutase than the other cultivars, while the catalase content of 'Hayward' was significantly higher than that of 'Hongyang' and 'Kuilv'. These results provided knowledge that could be implemented for the marketing, handling and post-harvest technologies of the different kiwifruit cultivars., Competing Interests: The authors declare there are no competing interests., (©2021 Li et al.)

- Abstract
Objective: To observe the effect of electroacupuncture(EA) intervention on the behavior, colon and midbrain substantia nigra α-synuclein(α-syn) expression in Parkinson's disease (PD) mice, so as to explore the mechanism of early EA on prevention of PD., Methods: C57BL/6J mice were randomly divided into blank, model and EA groups, with 8 mice in each group. The PD mouse model was established by subcutaneous injection of rotenone. Mice in the EA group received EA (2 Hz, 1 mA) at "Quchi"(LI11), "Shangjuxu"(ST37) and acupuncture at "Shenting" (GV24)and "Tianshu"(ST25) for 10 min once daily, with 7 d for a course, a total of 8 courses. Behavioral tests of hanging and climbing poles were carried out before, during and after modeling. The expressions of a-syn in substantia nigra and colon were detected by Western blot and immunohistochemistry or immunofluorescence., Results: After 8 weeks of modeling, the mice in the model group showed symptoms such as listlessness, dim hair color, coldness and curling up. Compared with the blank group, the hanging score of the model group was significantly lower ( P <0.01), the pole climbing time and the expressions of α-syn protein in colon and substantia nigra were significantly increased ( P <0.01). Following intervention, mice in the EA group were always in good mental state, with shiny fur and stable body weight. The hanging scores was significantly higher and the pole climbing time and the expressions of α-syn protein in colon and substantia nigra were significantly down-regulated ( P <0.05, P <0.01) in the EA group relevant to the model group., Conclusion: Early EA intervention can delay the onset of PD induced by rotenone, which may be related to its effect in reducing the expression of α-syn in midbrain substantia nigra and colon.

- Abstract
Synaptic dysfunction and neuronal loss are related to cognitive impairment of Alzheimer's disease. Recent evidence indicates that regulating the phosphatidylinositol 3-Kinase (PI3K)/AKT/GSK-3β pathway is a therapeutic strategy for improving synaptic plasticity in Alzheimer's disease. Here, we investigated "olfactory three-needle" effects on synaptic function and the PI3K/AKT/GSK-3β signaling pathway in β-amyloid
1-42 (Aβ1-42 )-induced Alzheimer's disease rats. A three-needle olfactory bulb insertion for 28 days alleviated Aβ1-42 -induced Alzheimer's disease rats' cognitive impairment as assessed by performance in the Morris water maze test. Furthermore, the three-needle electrode inhibited neuro-apoptosis and neuro-inflammation. It significantly upregulated the protein expression of postsynaptic density protein 95, synaptophysin, and GAP43, indicating a protective effect on hippocampal synaptic plasticity. Additionally, the activation level of PI3K/AKT signaling and the phosphorylation inactivation of GSK-3β were significantly enhanced by the "olfactory three-needle". Our findings suggested that the three-needle acupuncture is a potential alternative to improve synaptic plasticity and neuronal survival of Alzheimer's disease brain in rodents., Competing Interests: The authors declare no competing interests., (© 2021 The Authors.

- Abstract
Municipal wastewater methanogenesis is one of the ways to utilize municipal wastewater resources.In this study, a biofilter used to treat actual municipal wastewater was employed to investigate the methanogenesis in a pilot-scale reactor. The method of rapid start-up, the influence of temperature on the reactor performance, and the changes in the microbial structure were investigated in the pilot-scale study. The rapid start-up of the biofilter reactor was achieved by the combination of intermittent and continuous operations. The effluent concentration of SCOD was 60 mg ·L
-1 at the stable operation stage. The biofilter was operated steadily at a temperature higher than 14℃, the accumulation of volatile fatty acids (VFA) was low, and the effluent concentrations of SCOD and TCOD were 69 mg ·L-1 and 90 mg ·L-1 , respectively. In addition, the metabolism of hydrolysis and methanogenesis tended to balance off under such conditions. However, the abundance of microorganisms that can hydrolyze organic matter and produce methane decreased. The abundance of Peptostreptococcaceae increased even the temperature was lower than 10℃, which typically increases VFA production. Therefore, the concentrations of effluent VFA and TCOD increased, but methane production decreased. The effluent concentration of SCOD was relatively stable. The microbial abundance and diversity were the richest at 19℃ in the reactor. The acetolactic methanogens were the dominant methanogens at low temperatures. The anaerobic biological filter for the treatment of urban sewage starts quickly and can resist the impact of continuous temperature reduction. Moreover, it does not need backwashing after running for nine months, and it is not easily clogged.Therefore,the functions of biological contact oxidation and filtration retention of the biological filter can be more fully utilized.- Published

- Abstract
Upflow anaerobic filter (UAF) with actual domestic wastewater were examined in this study. The Impacts of hydraulic retention time (HRT) on the performance of a UAF and a primary methanogen group were investigated at mesophilic conditions. The chemical oxygen demand (COD) removal rate was more than 75% after 28 days acclimation at 35℃ and HRT of 24 h. With a gradual decrease in the HRT, the COD removal rate first increased and then decreased. When the HRT was 5 h, the COD removal rate was the highest, with an average 81.71% and a maximum of 87.18%. When the HRT decreased to 2.5 h, the average COD removal rate decreased to 75.12%. The methane produced per unit mass of substrate consumed (CH
4 /CODre ) and volume fraction increased with a decrease in HRT. When the HRT was 2.5 h, it reached 0.30 L·g-1 , and the volume fraction of methane was maintained at about 73%. The energy generated by the system met the energy demands of the peristaltic pump. Quantitative analysis of the primary methanogen group in the system indicates that Methanosarcinales is the dominant in the system. With a decrease in HRT, the abundances of acetoclastic and hydrogenotrophic methanogens increased significantly.- Published

Objective: To observe the effect of electroacupuncture (EA) on expression of 5-HT
1A receptor (5-HT1A R) and c-fos proteins in the hypothalamus and colon tissues in functional diarrhea (FD) rats so as to explore its underlying mechanisms in improving intestinal function via brain-gut axis., Methods: A total of 40 SD rats were randomized into blank control, model, EA Tianshu (ST25)-Dachangshu (BL25, ST25-BL25) and EA Quchi (LI11)- Shangjuxu (ST37, LI11-ST37) groups. The FD model was established by gavage of Folium Sennae (10 mg/kg) and constraint immobilization once daily for 29 days. EA (10 Hz/50 Hz, 1.5 mA) was applied to bilateral ST25 and BL25 in EA ST25-BL25 group, and bilateral LI11 and ST37 in EA LI11-ST37 group for 20 min, once daily for successive 10 days. The expression of 5-HT1A R and c-fos protein in the hypothalamus and colon tissues was determined by using Western blot. The state of stool was recorded for calculating the loose stool rate and diarrhea index., Results: After modeling, the loose stool rate, diarrhea index and expression levels of 5-HT1A R and c-fos proteins in the colon and hypothalamus tissues were obviously increased in the model group in contrast with the blank control group( P <0.01, P <0.05). Following EA intervention, the loose stool rate and diarrhea index, the expression levels of 5-HT1A R and c-fos proteins in the hypothalamus and colon in the EA ST25-BL25 group, and the expression of 5-HT1A R in the colon in the EA LI11-ST37 group were significantly down-regulated relevant to the model group ( P <0.01, P <0.05). No significant changes were found in loose stool rate and diarrhea index,and the expression levels of hypothalamic 5-HT1A R and hypothalamic and colonic c-fos proteins in the EA LI11-ST37 group ( P >0.05). The expression levels of 5-HT1A R protein in the hypothalamus and c-fos protein in the hypothalamus and colon in the EA LI11-ST37 group were significantly up-regulated relevant to the EA ST25-BL25 group ( P <0.05)., Conclusion: EA of ST25-BL25 can down-regulate expression of 5-HT1A R and c-fos proteins in the hypothalamus and colon tissue in FD rats, which may contribute to its function in improving symptoms of FD possibly via brain-gut axis.- Published

- Abstract
Defective ciliogenesis causes human developmental diseases termed ciliopathies. Microtubule (MT) asters originating from centrosomes in mitosis ensure the fidelity of cell division by positioning the spindle apparatus. However, the function of microtubule asters in interphase remains largely unknown. Here, we reveal an essential role of MT asters in transition zone (TZ) assembly during ciliogenesis. We demonstrate that the centrosome protein FSD1, whose biological function is largely unknown, anchors MT asters to interphase centrosomes by binding to microtubules. FSD1 knockdown causes defective ciliogenesis and affects embryonic development in vertebrates. We further show that disruption of MT aster anchorage by depleting FSD1 or other known anchoring proteins delocalizes the TZ assembly factor Cep290 from centriolar satellites, and causes TZ assembly defects. Thus, our study establishes FSD1 as a MT aster anchorage protein and reveals an important function of MT asters anchored by FSD1 in TZ assembly during ciliogenesis.

Purpose: To evaluate the methodological and reporting quality of systematic reviews (SRs) on acupuncture treatment for women with polycystic ovarian syndrome (PCOS)., Methods: A comprehensive search on multiple databases was performed. Methodological and reporting quality of reviews were assessed by revised assessment of multiple systematic reviews (AMSTAR 2) and preferred reporting items for SRs and meta-analyses (PRISMA), respectively., Results: Ten SRs were included. Among the SRs using AMSTAR 2, two achieved a good overall rating (percentage of items with "yes" > 50%) and severe limitation existed in eleven items (percentage of items with "yes" < 50%). Among the SRs using PRISMA, six reviews achieved a good overall rating (percentage of items with "yes" > 50%), while twelve items were poorly reported (percentage of items with "yes" < 50%)., Conclusion: There were many deficiencies in the methodological and reporting quality of SRs assessing acupuncture in women with PCOS., (Copyright © 2018 Elsevier Ltd.

- Abstract
Abscisic acid (ABA) plays a key role in plant growth and development. The effect of ABA in plants mainly depends on its concentration, which is determined by a balance between biosynthesis and catabolism of ABA. In this study, we characterize a unique UDP-glucosyltransferase (UGT), UGT71C5, which plays an important role in ABA homeostasis by glucosylating ABA to abscisic acid -: glucose ester (GE) in Arabidopsis (Arabidopsis thaliana). Biochemical analyses show that UGT71C5 glucosylates ABA in vitro and in vivo. Mutation of UGT71C5 and down-expression of UGT71C5 in Arabidopsis cause delay in seed germination and enhanced drought tolerance. In contrast, overexpression of UGT71C5 accelerates seed germination and reduces drought tolerance. Determination of the content of ABA and ABA-GE in Arabidopsis revealed that mutation in UGT71C5 and down-expression of UGT71C5 resulted in increased level of ABA and reduced level of ABA-GE, whereas overexpression of UGT71C5 resulted in reduced level of ABA and increased level of ABA-GE. Furthermore, altered levels of ABA in plants lead to changes in transcript abundance of ABA-responsive genes, correlating with the concentration of ABA regulated by UGT71C5 in Arabidopsis. Our work shows that UGT71C5 plays a major role in ABA glucosylation for ABA homeostasis., (© 2015 American Society of Plant Biologists. All Rights Reserved.)

- Abstract
Henan Province in China has a major epidemic of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). Chinese medicine (CM) has been used throughout the last decade, and a management modality was developed, which can be described by unified-planning, graded-administration, and centralized-controlling (UGC). The UGC modality has one primary concept (patient-centered medicine from CM theory), four basic foundations (classifying administrative region, characteristics of CM on disease treatment, health resource conditions, and distribution of patients living with HIV), six important relationships (the "three uniformities and three combinations," and the six relationships therein guide the treatment of AIDS with CM), and four key sections (management, operation, records, and evaluation). In this article, the authors introduce the UGC modality, which could be beneficial to developing countries or resource-limited areas for the management of chronic infectious disease.

- Abstract
Objective: To investigate the clinical outcome of 489 patients with diffuse large B-cell lymphoma (DLBCL), and to identify factors associated with the clinical outcome., Methods: Medical records of 489 DLBCL patients admitted to the West China Hospital of Sichuan University from Jan 2000 to Dec 2010 were retrospectively reviewed. The patients were divided into CHOP and RCHOP (rituximab plus CHOP) groups depending on their chemotherapy regimens. The clinical outcomes of the two groups of patients were compared., Results: The RCHOP group had a higher response rate than the CHOP group (84.3% vs. 75.6%, P = 0.015). The multivariate analysis showed that splenomegaly, low absolute lymphocyte count (ALC), high IPI scores, and CHOP was associate with the low overall-response rate. In the CHOP group, low ALC (OR = 2.060, 95% CI: 1.159-3.661, P = 0.014) and high IPI scores (OR= 2. 157, 95% CI: 1.170-3.978, P = 0.014) were associate with low response rate. In the RCHOP group, anemia (OR = 3.010, 95% CI: 1.238-7.314, P = 0.015) and high IPI scores (OR = 2.872, 95% CI: 1.193-6. 914, P = 0.019) were associate with low response rate. For patients with 0.8 x 10(9)/L-1.0 x 10(9)/L ALC, RCHOP therapy was more effective than CHOP. The expression of Bcl-2 and the phenotype of immuno-classification (GCB/non-GCB) were not associated with the difference of overall response rate between the CHOP and RCHOP groups., Conclusion: RCHOP therapy increases the overall response rate compared with CHOP alone. Low ALC and anemia is associate with low response rate to CHOP and RCHOP therapy, respectively.

- Abstract
Objective: To analyze clinical features and the differences of GCB and non-GCB phenotypes for diffuse large B-cell lymphoma (DLBCL) in different age groups, Ki-67 index and international prognostic index (IPI)., Methods: Clinical data of 681 patients with DLBCL hospitalized in West China Hospital from January 2000 to December 2010 were retrospectively analyzed., Results: Of these DLBCL cases, the median age was 56 years old with a male predominance, 51.4% stage III-IV, 37.6% B symptoms, 30.2% IPI 3-5 scores, 49.8% from extranodal sites, 29.0% gastrointestinal tract infiltration, 38.3% low absolute lymphocyte count (ALC), 56.1% elevated serum lactate dehydrogenase (LDH) level, 83.0% elevated β(2)-microglobulin (β(2)-MG) level. B symptoms was associated with bone marrow involvement with the odds ratio 5.212 (95%CI 2.821 - 9.632, P = 0.000). Among 268 with DLBCL patients classified by Hans' classification, 28.4% were GCB and 71.6% non-GCB. The proportions of patients with HBsAg-positive, elevated serum LDH level and Bcl-2 positive expression in non-GCB group was higher than those in GCB group (P < 0.05). The differences between GCB and non-GCB DLBCL were not revealed in terms of age subgroups, Ki-67 expression status and IPI subgroups. The high (≥ 60%) Ki-67 group included more patients with extranodal site involvement compared with the low (< 60%) Ki-67 group (51.8% vs 38.7%, P = 0.008). The proportion of patents with low ALC in IPI 3-5 scores group was higher than in IPI 0-2 scores group (P = 0.000). The multivariate analysis showed that high IPI had statistically significant negative influence on survival (P = 0.000)., Conclusions: Most patients with DLBCL were middle-aged male from our data. The patients with primary nodal (PN) was almost equal to those with primary extranodal (PEN). The most frequent extranodal site was gastrointestinal tract. The non-GCB phenotype was significantly more common than GCB phenotype in this study, and the non-GCB group included more patients with HBsAg-positive and Bcl-2 positive expression. Low ALC was observed predominantly in the high risk group. IPI score was an independent prognostic indicator for survival.

- Abstract
Objective: To study the correlation between polymorphisms of genes with susceptibility to tuberculosis and the clinical characteristics of tuberculosis in Han population., Methods: Four hundred and fifty-nine tuberculosis inpatients of Han population in Shanghai Pulmonary Hospital from Jan 2007 to Dec 2008 were recruited. The clinical characteristics of tuberculosis (gender, fever, extent of lesions, cavity formation, hemoptysis, initial treatment and retreatment) were observed. The polymorphisms of VDR gene (variants in FokI and TaqI), NRAMP1 gene (variants in INT4, D543N and 3 UTR), MBL gene (variants in HL, YX and QP) and IFNG gene (variants in 874AT) were genotyped by a variety of SNP genotyping techniques. The correlation between polymorphisms of genes with susceptibility to tuberculosis and the clinical characteristics of the disease was analyzed by ANOVAs., Results: The frequency of CC, CT and TT variants of FokI in VDR gene in cases with fever were 54.7% (29/53), 13.2% (7/53) and 32.1% (17/53), respectively, compared to 40.6% (52/128), 30.5% (39/128) and 28.9% (37/128) in cases without fever, the difference being significant (χ² = 6.183, P < 0.05). In patients with CT variants, 15.2% (7/46) had fever, while in patients with non-CT variants, 34.1% (46/135) had fever (χ² = 5.891, P < 0.05), suggesting that patients with CT variants were less likely to have fever. The frequencies of TT + TC and CC variants of QP in the MBL gene in initial treatment cases were 28.3% (60/212) and 71.7% (152/212), respectively, compared to 19.1% (41/215) and 80.9% (174/215) in retreatment cases, the difference being significant (χ² = 5.038, P < 0.05). No significant correlation was observed between the other variants and the clinical characteristics of tuberculosis (χ² = 0.001 - 2.732, P > 0.05)., Conclusions: The polymorphisms of FokI in VDR gene was associated with fever among the clinical characteristics of tuberculosis, and patients with CT variants might be protected from fever. The polymorphisms of QP in MBL gene might be associated with recurrence of tuberculosis.

- Abstract
Objective: To propose a method for predicting the postoperative anterior chamber depth value (ACD) based on the evaluation standard of contrast sensitivity function (CSF)., Methods: In a personalized eye model, the natural lens was replaced with an artificial lens, and the tracing method based on ZEMAX software was utilized to simulate the pseudophakic optical system. The best MTF curve was obtained through optical optimization to calculate the CSF and determine the best contrast sensitivity (CS) curve. The best ACD value was acquired according to the CSF curve. The data form 10 cataract cases without retinal diseases were obtained and the postoperative ACD value was predicted using Holladay, Hoffer Q, SRK/T and the proposed method., Results: Consistency analysis of the results showed that all the ACD values predicated by the 4 methods fell in 95% consistency within the boundaries, and the differences in the largest absolute value between the 3 methods (Holladay, Hoffer Q, and SRK/T) and the proposed method were 0.73 mm, 0.65 mm, and 0.68 mm, and the calculation results of the mean value were 5.846 mm, 5.804 mm, and 5.825 mm. Clinically, the two methods were deemed to have good consistency., Conclusion: The proposed method establishes a connection between the contrast sensitivity curve and ACD to allow better refraction adjustment for the patients.

- Abstract
Objective: To explore the effect of "Xiusanzhen" [electroacupuncture (EA) of bilateral "Yingxiang" (LI 20) and "Yintang" (EX-HN 3)] on activities of hippocampal muscarinic cholinergic receptor (mAChR) and the involved neural path in Alzheimer Disease(AD)rats., Methods: Forty Sprague Dawley rats were randomly divided into normal control, model, olfactory nerve severing (ONS)-EA of "Xiusanzhen" (ONS-EA) and EA of "Xiusanzhen" (EA) groups. AD model was established by intra-hippocampal injection (AP: 3.5 mm, L:2 mm, H: -2.8 mm) of Abeta(1-40) starch-like peptide (10 microg/2 microL) under the aid of a microsyringe installed in a brain stereotaxis instrument. For rats of the ONS-EA group, the olfactory nerve was severed by using a surgical knife after drilling a hole on the skull (5 mm anterior to the bregma, L, R: 2 mm). The mAChR density, and its maximum binding capacity (Bmax) and dissociation constant (Kd) of the hippocampus tissue were measured by using radio-ligand binding analysis and Lowry's microamount protein assay., Results: In comparison with the normal control group, the hippocampal mAChR density and its Bmax in the model group were decreased remarkably (P < 0.05), while the Kd of M-receptor in the model group was increased remarkably (P < 0.05). In comparison with the model group, hippocampal mAChR density and its Bmax in the EA group were up-regulated obviously (P < 0.05), while the Kd of mAChR in the EA group was down-regulated significantly (P < 0.05). No significant differences were found between the model and ONS-EA groups in mAChR density and its Bmax and Kd (P > 0.05)., Conclusion: "Xiusanzhen"-EA can effectively up-regulate hippocampal mAChR density and Bmax and down-regulate Kd of M-receptor of hippocampus in AD rats, which is dependent on the intact olfactory nerve pathway.

- Abstract
Objective: To investigate the distribution of polymorphisms of SLC11A1 gene, VDR gene, MBL gene and IFNG gene with susceptibility to tuberculosis (TB) in Chinese Han population suffering from drug-sensitive TB and drug-resistant TB so as to identify the correlation between gene polymorphisms and the development of drug-resistant TB., Methods: Single nucleotide polymorphisms (SNP) of VDR gene, SLC11A1 gene, MBL gene, IFNG gene were typed and analyzed by pyrosequencing, Real-time Probe and SNaPshot among 229 patients with drug-sensitive TB and 230 patients with drug-resistant TB., Results: The polymorphic foci of VDR gene from the drug-sensitive TB group and the drug-resistant TB group showed no significant difference (P > 0.05). The genotype of INT4 site and allelic frequency of SLC11A1 gene for drug-sensitive TB group were significantly different from those for drug-resistant TB group (P = 0.031, 0.046). If recessive inheritance was assumed, the genotypes of INT4 site from the two groups were significantly different (OR = 5.756, 95%CI: 1.261 - 26.269, P = 0.011). Considering the relationship between OR values under various combination, our findings confirmed that the genetic mode of INT4 site was in accordance with recessive inheritance. The genotypes of Q/P site and allelic frequencies of MBL gene from drug-sensitive and drug-resistant groups were significantly different (P = 0.029, 0.033). The difference still existed under the hypothesis of recessive inheritance (OR = 9.290, 95%CI: 1.167 - 73.949, P = 0.011). The polymorphic foci of IFNG gene from the two groups showed no significant difference., Conclusion: INT4 sites on SLC11A1 gene and Q/P site on MBL gene were probably associated with the development of drug-resistant TB in Chinese Han population. Further study on this issue would be helpful in locating the population at high risk of drug-resistant TB and exploring the effective intervention to decrease the incidence of this disease.

- Abstract
Objective: To observe the effect of electroacupuncture (EA) of "Xiusanzhen" [3 acupoints, i.e., bilateral "Yingxiang" (LI 20) and "Yintang" (EX-HN 3)] on expression of B-cell lymphoma/leukemia-2 (Bcl-2, an antiapoptosis protein) and Bax (a protein for promoting apoptosis) in the hippocampus in Alzheimer disease (AD) rats, so as to explore its clinical mechanisms underlying relieving AD., Methods: A total of 40 Sprague Dawley rats were randomly divided into normal control, AD model, EA and olfactory nerve transaction(ONT) + EA groups, with 10 rats in each. AD model was established by injection of beta-amyloid (Abeta)(1-40) (2 microL containing 10 microg) into the hippocampus (Bregma: 3.5 mm, L: 2.0 mm, H: -2.8 mm below dura), and the ON was sectioned by using a fine needle. EA (80-100 Hz, 1-3 mA) was applied to bilateral LI 20 and EX-HN 3 for 10 min, once daily (except Saturdays and Sundays) for 6 weeks. The expression of Bcl-2 and Bax of hippocampus was measured by immunohisto-chemistry., Results: Compared with the normal control group, the expression of Bcl-2 of hippocampus was significantly lower in the AD model group (P<0.05), and that of Bax in AD model group was much higher (P<0.01). In comparison with the model group, the expression of hippocampal Bcl-2 was up-regulated significantly (P<0.01), and that of hippocampal Bax protein downregulated considerably in the EA group (P<0.01). No significant differences were found between AD model and ONT + EA groups in the expression of hippocampal Bcl-2 and Bax proteins (P>0.05), suggesting a necessary premise condition for EA in regulating hippocampal Bcl-2 and Bax expression., Conclusion: "Xiusanzhen" can regulate the expression of hippocampal Bcl-2 and Bax proteins in AD rats, which may contribute to its clinical effect in relieving AD, and the therapeutic effect depends on the integrity of the olfactory nerve pathway.

- Abstract
Plasma-derived antithrombin (pAT) is often used for the treatments of disseminated intravascular coagulation (DIC) patients. In this paper, the recombinant adenovirus vector encoding human antithrombin (AT) cDNA was constructed and directly infused into the mammary gland of two goats. The recombinant human antithrombin (rhAT) was purified by heparin affinity chromatography from the goat milk, and then used in the treatment of thirty lipopolysaccharide (LPS) induced DIC rats. A high expression level of rhAT up to 2.8 g/l was obtained in the milk of goats. After purification, the recovery rate and the purity of the rhAT were up to 54.7 +/- 3.2% and 96.2 +/- 2.7%, respectively. In blood of the DIC rat model treated with rhAT, the levels of antithrombin and thrombin-antithrombin (TAT) were augmented significantly; meanwhile the consumption of fibrinogen and platelet was reduced significantly, and the increase of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) concentration was restrained modest and non-significant. For the above DIC indexes, there were no differences between pAT and rhAT (P > 0.05). Our results demonstrated that the way we established is a pragmatic tool for large-scale production of rhAT, and the rhAT produced with this method has potential as a substitute for pAT in the therapy of DIC patients.

- Abstract
Objective: To observe the effect of electroacupuncture (EA) of "Xiusanzhen" [bilateral "Yingxiang" (LI 20) + "Yintang" (GV 29)] on learning-memory ability and hippocampal somatostatin (SS) and arginine vasopressin (AVP) contents in vascular dementia (VD) rats., Methods: Forty SD rats were randomly divided into control, VD model, VD plus olfactory bulb lesion (OBL, destroyed by electro-coagulation) and EA groups, with 10 cases in each. VD model was established by 4-vessel occlusion. Morris maze tests were conducted for evaluating the rats' learning and memory ability. EA (1-3 mA, 80/100 Hz) was applied to bilateral LI 20 and GV 29 in VD + OBL and EA groups for 10 min, once daily (except Saturdays and Sundays) for 6 weeks. The contents of SS and AVP in hippocampus tissue were measured by radioimmunoassay., Results: In comparison with control group, the average escape latency (AEL) prolonged significantly and the target-platform crossing times (TPCT) decreased remarkably in VD model group (P < 0.01). In comparison with VD model group, the AEL was shortened and TPCT increased remarkably in EA group (P < 0.01). No significant differences were found between VD model and VD + OBL groups in the AEL and the TPCT (P > 0.05). Hippocampal SS and AVP contents in VD model group were significantly lower than those in control group (P < 0.05), while those in EA group were markedly higher than those in VD model group (P < 0.05). No significant differences were found between VD model and VD + OBL groups in SS and AVP contents (P > 0.05)., Conclusion: EA of "Xiusanzhen" can improve VD rats' learning-memory ability, which may be related to its effects in raising hippocampal SS and AVP contents and to the intact olfactory pathway.
