Abstract
Objective: To explore the therapeutic efficacy and factors influencing the sequential combination of nucleos(t)ide analogues (NAs) with pegylated interferon alpha (Peg-IFN-α) in the treatment of patients with chronic hepatitis B (CHB). Methods: 144 CHB cases with NAs treatment for more than 1 year, HBV DNA < 20 IU/ml, hepatitis B surface antigen (HBsAg) quantification < 3 000 IU/ml, treated with a sequential combination of Peg-IFN-α treatment for 48 to 96 weeks, and followed up were selected from the Fifth Medical Center of the PLA General Hospital between May 2018 and May 2020. Intention-to-treat analysis was used to measure the HBsAg clearance rate at 96 weeks. The Kaplan-Meier method was used to compute the cumulative HBsAg clearance rate at 96 weeks. Univariate and multivariate logistic regression were used to analyze the factors influencing HBsAg clearance at 48 weeks of sequential combination therapy. Univariate and multifactorial COX proportional hazard models were used to analyze the factors influencing HBsAg clearance following 96 weeks of prolonged PEG-IFN-α treatment. The receiver operating characteristic curve was used to assess the predictive value of factors influencing HBsAg clearance. A Mann-Whitney U test was used to compare the measurement data between groups. The count data was compared using the χ(2) test between groups. Results: 41 (28.47%) cases achieved HBsAg clearance at 48 weeks of sequential combination therapy. The HBsAg clearance rate at 96 weeks was 40.28% (58/144) by intention-to-treat analysis. The Kaplan-Meier method computed that the cumulative HBsAg clearance rate at 96 weeks was 68.90%. Multivariate logistic regression analysis showed that HBsAg quantification at baseline (OR = 0.090, 95%CI: 0.034-0.240, P < 0.001) and a 24-week drop in HBsAg level (OR = 7.788, 95%CI: 3.408-17.798, P < 0.001) were independent predictors of HBsAg clearance in CHB patients treated sequentially in combination with NAs and Peg-IFN-α for 48 weeks. Receiver operating characteristic curve analysis showed that the baseline HBsAg quantification [area under the receiver operating characteristic curve (AUC), 0.911, 95% CI: 0.852-0.952)] and 24-week drop in HBsAg level (AUC = 0.881, 95%CI: 0.814-0.930) had equally good predictive value for 48-week HBsAg clearance, but there was no statistically significant difference between the two (Z = 0.638, P = 0.523). The value of the combination of baseline HBsAg quantification and 24-week drop in HBsAg level (AUC = 0.981, 95%CI: 0.941-0.997) was superior to that of single baseline HBsAg quantification (Z = 3.017, P = 0.003) and 24-week drop in HBsAg level (Z = 3.214, P = 0.001) in predicting HBsAg clearance rate at 48 weeks. Multivariate COX proportional hazards model analysis showed that HBsAg quantification at 48 weeks (HR = 0.364, 95%CI: 0.176-0.752, P = 0.006) was an independent predictor of HBsAg clearance with a prolonged course to 96 weeks of Peg-IFN-α treatment. Conclusion: The HBsAg clearance rate can be accurately predicted with baseline HBsAg quantification combined with a 24-week drop in HBsAg level in patients with CHB who are treated with a sequential combination of NAs and Peg-IFN-α therapy for 48 weeks. Prolonging the course of Peg-IFN-α treatment can enhance the HBsAg clearance rate's capability. An independent predictor of HBsAg clearance is HBsAg quantification at 48 weeks of sequential combination therapy with a prolonged course of 96 weeks of Peg-IFN-α treatment.

Abstract
Objective: To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test. Methods: This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ (2) test. A kappa test was used to compare the consistency between groups. Results: After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea (Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences (P < 0.001). Conclusion: The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Abstract
Objective: To understand the etiological characteristics of 2 serotypes of Salmonella strains isolated from a foodborne disease outbreak. Methods: A total of 11 anal swabs of the cases, 13 suspected contaminated food and 10 environmental samples were collected from a foodborne disease outbreak occurred on September 8, 2022 in a school. The anal swabs were enriched with selenite brilliant green enrichment broth (SBG) and brain heart infusion broth (BHI) respectively. PCR detection and culture of common intestinal pathogens were carried out. The suspected food samples were tested according to national standards for food safety. Multiple suspected Salmonella colonies were obtained and selected for serotype determination and whole genome sequencing. Serotypes were determined based on the whole-genome sequence, and clustering analysis was performed based on core genome single nucleotide polymorphism (SNP). Results: The positive rates of Salmonella in anal swabs and suspected food samples were 9/11 and 5/13 respectively. Both Salmonella Uganda and Salmonella Idikan were isolated from 4 anal swabs and 4 suspected food samples. For the remaining samples, only Salmonella Uganda or Salmonella Idikan was isolated in each sample. The positive rate of Salmonella in 11 anal swabs of the cases after BHI enrichment for 12 h and 24 h were all 9/11 in real-time PCR, same to the culture results. Salmonella Uganda and Salmonella Idikan formed two independent and genetically distant lineages in the clustering tree based on core genome SNP, and 0-14 and 0-23 SNP were observed in Salmonella Uganda and Salmonella Idikan respectively. Conclusions: This foodborne disease outbreak was probably caused by Salmonella Uganda and Salmonella Idikan, which both exhibited strong genetic diversity. The PCR based pathogen screening strategy plus pathogen enrichment for cases' annal swabs can be used in the routine outbreak investigation.

Abstract
Whether or not children with chronic hepatitis B (CHB) in the immune-tolerant phase need to be treated is one of the hot clinical issues that have not yet been clarified. Thus, in order to make clinical antiviral treatment decisions in children with an immune tolerant phase, a comprehensive understanding of the natural history of HBV infection, as well as its relationship with disease progression and whether prompt treatment can alter the natural history and prognosis, is very important. To that end, this article reviews the research progress of clinical antiviral therapy in the immune-tolerant phase for children with chronic hepatitis B over the last decade, while also discussing the treatment's safety, effectiveness, and related immunological mechanisms, so as to clarify the next key step in research orientation, provide direct evidence-based medical evidence for hepatologists to better diagnose and treat, and ultimately improve the clinical cure rate.

Direct-acting antivirals (DAAs) can strongly inhibit the replication of hepatitis C virus (HCV) and effectively clear the infection, but it may cause hepatitis B virus (HBV) reactivation, leading to severe liver damage and fulminate hepatitis in patients with HCV/HBV coinfection. In this review, we summarized the different replication process of HCV and HBV in infected hepatocytes and consequent innate immune response, and then discussed the molecular mechanism and clinical significance of HBV reactivation, and put forward the clinical precaution.

Abstract
The high incidence of chronic liver disease is a serious threat to public health, and the current comprehensive internal medicine treatment is ineffective. Liver transplantation is limited by the shortage of liver source and post-transplant rejection, and thus unmet the clinical needs. More importantly, cell therapy shows great promise for the treatment of chronic liver disease. Over recent years, domestic and foreign scholars have carried out a variety of cell therapy preclinical and clinical trials for critical liver disease, and achieved certain results, providing new methods for the treatment of chronic liver diseases. This review discusses the cell therapy research status and application progress, various existing problems and challenges, and key issues of mesenchymal stem cells in the treatment of chronic liver diseases.

Abstract
Objective: To assess and compare the accuracies and operating time of endodontic microsurgery performed by operators with different levels of experience in endodontics using computer-guided techniques including dynamic and static navigations in a surgical simulation model. Methods: Six pairs of three dimensional (3D)-printed models of upper and lower jaws were set up on dental manikins. A total of 120 teeth (10 teeth each jaw) were included in the models. Microsurgeries of osteotomy and root-resection were performed on the models by two operators with different experience, namely novices and experts, under of free hand (FH)(n=20), dynamic navigation (DN)(n=20), and static navigation (SN)(n=20) conditions, respectively. The duration of each operation was recorded. Cone-beam CT was taken for 3D-printed models before and after the operation. The path of preoperative surgery planning was simulated. The linear deviations at the entry and the end point and the angular deviation of the access path between the simulated and the actual operation were compared by the software. Results: Significant difference of the entry deviation was observed between the novices and the experts in the FH group [(1.44±0.49) and (1.02±0.58) mm] (q=4.67, P=0.020). There were no significant differences between the novices and the experts in the end point and angular deviations (P>0.05). For the novices, the entry deviations in both DN and SN groups [(0.76±0.32) and (0.66±0.20) mm] were significantly lower than those in FH group (q=7.58, P<0.001; q=8.66, P<0.001). The angular deviations in the abovementioned two groups (5.0°±3.5°, 3.9°±2.1°) were significantly lower than that in FH group (10.9°±6.1°) (q=7.38, P<0.001; q=8.70, P<0.001). For the experts, significant differences were found only in the angular deviations among DN, SN and FH groups (3.6°±1.9°, 3.2°±1.7° and 8.2°±3.9°) (q=5.74, P=0.001; q=6.29, P<0.001). The operation durations were significantly shortened for both the novices [(4.80±2.15), (1.09±0.48) min] (q=14.60, P<0.001; q=20.10, P<0.001) and the experts [(3.40±1.96),(1.02±0.34) min] (q=5.86, P<0.001; q=9.37, P<0.001) by using DN and SN techniques. Regarding the differences between tooth types, in FH group, the operating time on the anterior teeth was significantly shorter than that on the posterior teeth (q=8.14, P<0.001; q=5.20, P=0.007), while in DN and SN groups, there were no significant differences in the operating time between two tooth types (P>0.05). No significant differences were discovered in the accuracies on the anterior and posterior teeth among three techniques or between two kinds of operators (P>0.05). Conclusions: Dynamic and static navigation techniques could assist the clinicians, especially the novices, to improve the accuracies and shorten the operating time of osteotomy and root resection microsurgeries.

Abstract
Objective: To investigate the effect of programmed death receptor (PD)-1 antibody therapy in patients with hepatitis B-associated liver cancer. Methods: Data of 29 chronically infected HBV patients with liver cancer who received PD-1 antibody combined with tyrosine kinase inhibitor in the Department of Infectious Diseases of the Fifth Medical Center of PLA General Hospital from March 2020 to January 2021 were selected. At the same time, all of the above-mentioned hepatitis B virus (HBV) patients were treated with nucleos(t)ide analogues. Patients clinical diagnostic data, laboratory test results, tumor response and the incidence of adverse reactions were collected retrospectively to understand the overall safety, therapeutic anti-tumor effect, HBV changes condition and the correlation between HBV changes and anti-tumor PD-1 antibody efficacy, high viral load treatment condition, and HBV reactivation safety issues. Statistical analysis was performed by non-parametric rank sum test. Results: Therapeutic anti-tumor effect and safety profile were good in patients. The complete remission rate was reached 27.6%. Adverse reactions were mostly mild, and the incidence of serious adverse reactions was low. After 12 weeks of follow-up, HBV DNA and hepatitis B surface antigen (HBsAg) was quantitatively decreased (P < 0.05). HBV DNA and HBsAg were decreased more significantly in patients with progressive disease (PD), stable disease (SD) and partial response (PR) (P < 0.05). Five patients with HBV DNA ≥ 10(4) IU/ml had responded well to the tumor treatment without serious adverse reactions. One patient had a slight increase in HBV DNA and alanine aminotransferase, while there was no HBV reactivation and correlated liver damage. Conclusion: Patients with HBV-associated liver cancer who received combined therapy have good anti-tumor efficacy and safety profile. PD-1 treatment has a certain effect on HBV. Compared with non-responders, patients with tumor response have better antiviral treatment efficacy. The safety of treatment in patients with high viral load is manageable, and there are no safety issues related to HBV reactivation.

Abstract
As a digestive organ, the liver has the functions of metabolism, synthesis, and detoxification. It is also an immune organ and plays an important role in maintaining anti-infection, autoimmune stability, and anti-tumor. In particular, the liver has unique immunological advantages. Its immune cells can maintain the liver's immune homeostasis and participate in immunoregulation. A variety of immunotherapy is used in clinical trials for the treatment of difficult and critical liver diseases. This review mainly summarizes the recent clinical trials of immunotherapy in chronic hepatitis B, cirrhosis, hepatocellular carcinoma, and autoimmune liver disease.

Abstract
Objective: To observe the dynamic changes of serum RANTES during the treatment with nucleos(t)ide analogues combined with pegylated interferon alpha (peginterferon-α), and further analyze the predictive effect of RANTES on HBsAg clearance in patients with chronic hepatitis B. Methods: 98 cases of chronic hepatitis B with quantitative HBsAg < 3 000 IU/ml and HBV DNA < 20 IU/ml after≥1 year NAs treatment were enrolled. Among them, 26 cases continued to receive NAs monotherapy, 72 cases received NAs combined with pegylated interferon alpha therapy. The changes in RANTES during treatment were observed. The receiver operating characteristic curve was used to analyze the early changes of RANTES to predict the HBsAg clearance during 48 weeks. Results: During 48 weeks, 15 cases (20.83%) had achieved HBsAg clearance in combination group, while no patient had achieved HBsAg clearance in NAs group. The overall serum RANTES level had decreased from baseline in NAs and combination group. At week 48, in the combination group, the serum RANTES level was decreased more significantly in patients with HBsAg clearance than patients without. Further analysis showed that, in combination group, HBsAg clearance rate of patients with serum RANTES decreased at week 12 and 24 was higher than patients with elevated (29.17% vs. 4.17%, P = 0.014; 28.00% vs. 4.55%, P = 0.052), and quantitative HBsAg reduction was larger significantly [(1.49 ± 1.26) log(10)IU/ml vs. (0.73 ± 0.81) log(10)IU/ml, P = 0.017; (1.54 ± 1.27) log(10)IU/ml vs. (0.57 ± 0.56) log(10)IU/ml, P = 0.004]. Receiver operating characteristic curve analysis showed that the baseline quantitative HBsAg and the reduction in quantitative HBsAg and serum RANTES during the early period were predictors of HBsAg clearance after 48-week combination therapy. Furthermore, the combination of baseline quantitative HBsAg and 12 - or 24-week reduction of serum RANTES were better predictors of HBsAg clearance than that of baseline quantitative HBsAg combined with HBsAg decrease at week 12 or 24. The area under the receiver operating characteristic curve of the former was 0.925 and 0.939, while that of the latter was 0.909 and 0.929, respectively. Conclusion: Early reduction of serum RANTES at week 12 and 24 can predict HBsAg loss in CHB patients receiving addition of peginterferon-α to ongoing NAs Therapy, so serum RANTES could be one of the key immunological markers for predicting HBsAg clearance.

Abstract
Clinically, the incidence of end-stage liver disease including decompensated cirrhosis and liver failure is high, which seriously threatens people's health. The existing comprehensive internal medicine treatment is ineffective, and liver transplantation is still the most effective treatment method. However, the shortage of matching liver donors and other reasons constrain the development of liver transplantation, thus limiting the treatment of patients with end-stage liver disease. In recent years, domestic and foreign scholars have conducted many pre-clinical and clinical trials using a variety of cells, and have achieved certain results, providing a new method for the treatment of end-stage liver disease. This article reviews and discusses the existing problems, research status and application progress of varieties of cell therapy for end-stage liver diseases.

Abstract
Objective: To find the possible targets for the study and treatment of triple-negative breast cancer (TNBC), and to analyze and predict the key genes affecting the prognosis of TNBC by bioinformatics. Methods: Raw data on transcriptome sequencing of clinical specimens from patients with TNBC were searched by searching GEO Datasets in the National Center for Biotechnology Information (NCBI) database. The differential gene was then submitted to the Enrichr website for pathway enrichment. Survival analysis was used to finally identify the most significant differences in the prognosis of patients with TNBC. Results: Only ADAM9 gene showed a significant correlation with the poor prognosis of patients with TNBC (P<0.05), and ADAM9 only showed specificity associated with prognosis in patients with TNBC, and was not with other breast cancer types. Conclusion: ADAM9 gene has been proved to be related to the poor prognosis in patients with TNBC. Therefore, ADAM9 gene can be regarded as a possible key gene leading to lymph node metastasis and poor prognosis in patients with TNBC.

Abstract
OBJECTIVES To explore the barriers to early diagnosis of HIV infection and timely initiation of antiretroviral therapy (ART). METHODS We assessed the annual number and proportion of ART-naïve people living with HIV infection (PLWH) with severe immunosuppression in Shenzhen, China, from 2008 to 2019. Selected ART-naïve PLWHs with severe immunosuppression who were seeking treatment for the first time in the hospital in 2019 were subjected to an in-depth interview. RESULTS The proportion of severely immunosuppressed, ART-naïve PLWH decreased from 36.73% in 2008 to 8.94% in 2015, and then plateaued at approximately 10% from 2015 to 2019. Overall, 55 patients, 70% of whom were men who had sex with men, participated in the qualitative interviews. Ten of them delayed treatment after diagnosis, with a median [interquartile range (IQR)] interval of 5.83 (3.98-8.54) years between diagnosis and ART. More than 80% of the patients reported casual sexual contact within a median period of 6 years and with a median (IQR) of nine (4-20) casual sex partners. The major barriers to HIV testing and diagnosis included lack of knowledge about HIV and high-risk behaviours, low awareness about HIV testing, and resistance to HIV testing. The major barriers to ART initiation included lack of knowledge about the importance of ART and change of national ART eligibility policy, and HIV-related stress. CONCLUSIONS The number of PLWHs with severe immunosuppression who seek treatment remains high in Shenzhen, China. Thus, current HIV-related care programmes targeting access to early diagnosis and treatment need to be improved.

Abstract
OBJECTIVES Understanding the determinants of HIV immune control is important for seeking viable HIV prevention, treatment and curative strategies. The antigen-specific roles of CD8 T cells in controlling primary HIV infection have been well documented, but their abilities to control the latent HIV reservoir is less well studied. METHODS The scientific literature on this issue was searched on PubMed. RESULTS Recent reports have demonstrated that CD8 T cells are also involved in the control of viral replication in HIV-infected individuals receiving antiretroviral therapy (ART). However, based on accumulating evidence, the antiviral role of CD8 T cells in ART patients may not be achieved via an antigen-specific manner as HIV-specific CD8 T cells can sense, but not effectively eliminate, cells harbouring intact provirus without first being activated. Our recent study indicated that virtual memory CD8 T cells, a semi-differentiated component of CD8 T cells, may be involved in the mechanism restraining the HIV DNA reservoir in ART patients. CONCLUSIONS In this review, we summarize recent findings on the role of CD8 T cells in controlling HIV, highlighting differences between conventional antigen-specific and innate-like CD8 T cells. A better understanding of the roles of CD8 T cells during HIV infection should benefit the informed design of immune-based treatment strategies.

Abstract
Chronic hepatitis B virus (HBV) infection remains a major world public health problem. Current guidelines of chronic hepatitis B (CHB) suggest the clinical cure as the ideal thearapeutic goal. Although the optimization of the existing antiviral treatment can make some patients achieve clinical cure, but for most patients with chronic hepatitis B, it is difficult to achieve clinical cure according to the existing antiviral treatment plan. The medical community has begun to work together to seek new treatment strategies, especially the immune intervention measures aimed at restoring the immune response in the liver microenvironment. Notably, immune antiviral response plays a crucial role in HBV clearance, and the clinical cure of chronic hepatitis B is finally achieved through the optimized combination of antiviral and immunomodulatory drugs.

Abstract
The highly contagious novel coronavirus pneumonia (COVID-19) that broke out in December 2019 has brought huge threats and losses to human society, so it has been the concern of every countries government. Presently, there are no specific drugs for COVID-19; however, a variety of potentially effective antiviral drugs, vaccines, cell therapies, traditional Chinese medicine and other methods are in clinical trials. Liver injury is a common complication of patients receiving COVID-19 treatment and its possible high incidence may affect the outcome of the disease. The pathogenesis of COVID-19 combined with liver injury in existing studies is still unclear, and relevant guidelines and expert consensuses are insufficient for clinical diagnosis and treatment. Therefore, the relevant progress and issues are now reviewed here.

Abstract
The treatment options for liver cancer and liver cirrhosis are limited. Cell therapy (immune cells, stem cells) can significantly improve the therapeutic effect by actively regulating body's immunity. In addition, when choosing different methods of cell therapy, clinicians should also fully consider the adverse reactions associated with cell therapy. This article reviews the progress of cells therapy in clinical trials of liver cancer and liver cirrhosis, including therapeutic mechanism, advantages, disadvantages and limitations.

Abstract
OBJECTIVE To evaluate the safety and efficacy of allogeneic natural killer (NK) cells in the treatment of primary hepatocellular carcinoma (HCC), and to elucidate the mechanism of NK cells therapy. METHODS Twenty-one patients with primary HCC treated with allogeneic NK cells at the Fifth Medical Center of the PLA General Hospital were followed up for 1 year. Peripheral blood mononuclear cells (PBMCs) were isolated from patient-related donors and cultured in vitro for 15 days and infused to the patients in two consecutive days. Clinical data and laboratory data were collected and analyzed, including survival, clinical features, imaging changes, hematology, immunology, and biochemical indicators to evaluate the safety and efficacy of allogeneic NK cell therapy. The changes of peripheral blood lymphocyte subsets after treatment were also analyzed to explore the possible anti-tumor mechanisms. RESULTS (1) Of the 21 patients with primary HCC, 11 patients were treated once, 5 patients were treated twice, and 5 patients were treated 3 times. After allogeneic NK cells infusion, 10 patients had fever, 1 patient had slight hepatalgia and 1 patient had slight headache, no other adverse events occurred including acute and chronic graft-versus-host disease (GVHD). They resolved spontaneously within 8 hours without other treatment. (2) The total disease control rate was 76.2% during one-year follow-up. Among them, the patients with Barcelona clinic liver cancer (BCLC) stage A had a disease control rate of 100%, stable disease (SD) in 10 cases; BCLC stage B patients had a disease control rate of 60%, partial response (PR) in 1 case, and SD 2 in cases; BCLC stage C patients had a disease control rate of 50%, complete response (CR) in 1 case, and 2 cases of PR. (3) The frequencies of NK cells and CD8+ T cells in peripheral blood were significantly lower than that before at 24 hours after treatment, and the frequencies of CD4+ T cells and CD4/CD8 were significantly higher than the baseline. CONCLUSION Allogeneic NK cells have good safety and efficacy in the treatment of primary HCC. The anti-tumor effect of the allogeneic NK cells may play an important role in the activation of the patient's natural immune system and delay disease progression, suggesting that allogeneic NK cells combined with sorafenib may be a very effective treatment for advanced HCC, and further large-sample multicenter randomized controlled clinical trials are needed to validate this result.

Abstract
Objective: To evaluate the incidence, and the characteristics of organ failure in relationship to prognosis in hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF) patients using chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score for judgments of clinical treatment and prognosis. Methods: Clinical data of 316 patients who were diagnosed as HBV-ACLF during hospitalization from February 2015 to February 2016 were retrospectively analyzed. Intrahepatic and extrahepatic organ failures were assessed according to CLIF-SOFA score, and the relationship between clinical characteristics and prognosis was analyzed. Continuity variables were analyzed by analysis of variance, or Kruskal-Wallis H test. Comparison of the categorical data were done using χ (2) or Fisher's exact test, and the predictive efficacy of various prognostic scores was compared using the area under the receiver operating characteristic curve (AUROC) and Z-test. Results: Of 316 cases (87.3% men) of HBV-ACLF, the mean age was (45 ± 11) years old. 78.8% of patients with underlying liver disease had hepatitis B virus induced cirrhosis. Mortality rates in patients without liver transplantation at 28 days, 90 days and 180 days were 20.5% (63/307), 36.7% (110/300) and 39.2% (116/296), respectively. According to the CLIF-SOFA score, 89.9% (284 patients) had organ failure at baseline, of which 97.5% had liver failure (Total bilirubin ≥ 12 mg/dl) and only 2.5% had coagulation, kidney, circulation or respiratory failure without liver failure. Besides liver failure, the incidence of extrahepatic organ failure was coagulation (23.1%), kidney (5.7%), brain (3.8%), circulation (1.3%) and respiratory failure (0.3%). With increasing number of organ failure, the mortality rate of two and three or more organ failures were 69.6% and 69.2%, respectively, which was significantly higher than that of single organ failure and non-organ failure patients (27% and 6.9%, respectively; P < 0.001). Liver failure with coagulation failure (International normalized ratio≥2.5 or platelet count≤20×10(9)/L) had worst prognosis with a mortality rate of up to 75% at 90 days. Conclusion: According to the CLIF-SOFA score, the main organ failure in patients with HBV-ACLF in China is liver failure. The mortality rate in patients with two or more organ failures is as high as 70% within 3 months. Therefore, timely manner liver transplantation should be considered.

Abstract
Silicosis is an irreversible lung disease resulting from long-term inhalation of occupational dust containing silicon dioxide. However, the pathogenesis of silicosis has not been clearly understood yet. Accumulating evidence suggests that miR-29 may have a significant anti-fibrotic capacity, meanwhile it may relate to Wnt/β-catenin pathway. The purpose of this study was to discuss the role of miR-29 in the progression of silicosis. A lentiviral vector was constructed, named Lv-miR-29c, which was overexpressing miR-29c. In vivo, intratracheal treatment with Lv-miR-29c significantly increased expression of miR-29c, and reduced expression of β-catenin, matrix metalloproteinase (MMP)-2, and MMP-9 in the lung and levels of transforming growth factor-beta 1 (TGF-β1) and interleukin-6 (IL-6) in bronchoalveolar lavage fluid, and notably attenuated pulmonary fibrosis as evidenced by hydroxyproline content in silica-administered mice. These results indicated that miR-29c inhibited the development of silica-induced lung fibrosis. Thus, miR-29c may be a candidate target for silicosis treatment via its regulation of the Wnt/β-catenin pathway.

Abstract
Adaptive immunity, especially the cellular immunity mediated by T lymphocytes, plays an important role in the body's fight against hepatitis C virus (HCV) infection. The clearance of HCV requires a strong, sustained, and multi-epitope response from specific T lymphocytes, and the dysfunction of specific T lymphocytes is the major reason for chronic infection. Effective treatment can restore the function of specific T lymphocytes to a certain extent. This article reviews the features and related mechanisms of immune response from specific T lymphocytes when the prognosis of patients with HCV infection is different.

Abstract
Worldwide, some 240 million people have chronic hepatitis B virus (HBV), with the highest rates of infection in Africa and Asia. Our understanding of the natural history of HBV infection and the potential for therapy of the resultant disease is continuously improving. New data have become available since the previous APASL guidelines for management of HBV infection were published in 2012. The objective of this manuscript is to update the recommendations for the optimal management of chronic HBV infection. The 2015 guidelines were developed by a panel of Asian experts chosen by the APASL. The clinical practice guidelines are based on evidence from existing publications or, if evidence was unavailable, on the experts' personal experience and opinion after deliberations. Manuscripts and abstracts of important meetings published through January 2015 have been evaluated. This guideline covers the full spectrum of care of patients infected with hepatitis B, including new terminology, natural history, screening, vaccination, counseling, diagnosis, assessment of the stage of liver disease, the indications, timing, choice and duration of single or combination of antiviral drugs, screening for HCC, management in special situations like childhood, pregnancy, coinfections, renal impairment and pre- and post-liver transplant, and policy guidelines. However, areas of uncertainty still exist, and clinicians, patients, and public health authorities must therefore continue to make choices on the basis of the evolving evidence. The final clinical practice guidelines and recommendations are presented here, along with the relevant background information.

Abstract
BACKGROUND Programmed death-1/PD-1 ligand-1 (PD-1/PD-L1) costimulatory signals may play an important role in T-cell-induced immune response. The aim of this study is to investigate the role of the PD-1/PD-L1 costimulatory pathway on immunotolerance induction in mouse pancreatic islet transplantation. METHODS Full-length mouse PD-L1 cDNA was subcloned into pShuttle-GFP-CMV(-) shuttle plasmid. The product was cut by certain restriction endonuclease and ligated with pAdxsi vector. The adenovirus bone plasmid was transformed into DH5α-competent bacteria. After linearization, the recombined adenovirus DNA was transfected into 293 cells for package and amplification. Streptozotocin was injected intraperitoneally into C57BL/6 (H-2(b)) mouse to induce diabetic model recipient. Recipients were randomly divided into 3 groups. Group A was the control. Group B and group C were injected with Ad-EGFP and Ad-PD-L1 through the tail vein, respectively, 1 day before islet transplantation. The 300 to 400 islets of DBA/2 (H-2(d)) were transplanted into the renal subcapsular space of the diabetic model recipient. We monitored and analyzed the blood glucose levels and the survival time of grafts after transplantation. RESULTS Recombinant adenovirus Ad-PD-L1 had high efficiency expression of PD-L1 in recipient mouse. The blood glucose concentration of mice in the Ad-PD-L1 gene treatment group was obviously lower than that of the control and Ad-EGFP treatment groups and was stable and kept within the normal range at post-transplant 21 days. The survival time of grafts in the Ad-PD-L1 group (27.6 ± 3.5 days) was significantly longer than in the control (7.8 ± 0.33 days) and Ad-EGFP groups (7.6 ± 0.59 days), P < .01. Mixed lymphocyte response showed a specific decrease reaction of recipient lymphocyte vs donor lymphocyte. Flow cytometry detection showed that unsplit cells occupied 90% of recipient mouse lymphocytes, but unsplit cells among normal C57BL/6 mouse lymphocytes without Ad-PD-L1 gene treatment were 51 in the control group. The differences between them were significant (P < .01). CONCLUSION Recombinant adenovirus Ad-PD-L1 has been successfully constructed. In mouse pancreatic islet transplantation, it can suppress the activation of recipient T lymphocyte through the PD-1/PD-L1 costimulatory pathway, and significantly prolong the survival time of grafts.

Abstract
Irradiation from diverse sources is ubiquitous and closely associated with human activity. Radiation therapy (RT), an important component of the multiple radiation origins, contributes significantly to oncotherapy by killing tumor cells. On the other hand, RT can also cause some undesired normal tissue injuries that afflict numerous cancer patients. Although many promising radioprotective agents are emerging, few of them have entered the market successfully due to various limitations. At present, the most accepted hypothesis for the radiation-caused injury involves reactive oxygen species (ROS) generation. Superoxide dismutase (SOD), the unique enzyme responsible for the dismutation of superoxide radicals, is expected to occupy an indispensable position in the treatment of ROS-mediated tissue injuries originating from exposure to radiation. This review focuses on the mechanism of radioprotection by SOD at the tissue or organ level, cellular level, and molecular level, respectively, in order to provide references for further investigation of radiation injury and development of new radioprotectors.

Abstract
T helper (Th) 17 cells have been demonstrated to participate in the pathogenesis of HBV-associated liver damage. However, little is known regarding the immunopathogenic role of liver fibrosis in patients with HBV-associated liver cirrhosis. The aims of this study were to evaluate whether Th17 cells are related to disease progression in patients and to explore the possible mechanisms. The frequencies of circulating Th17 cells were analysed in 78 patients with hepatitis B and cirrhosis (Child A: 34; Child B: 22; Child C 22) and matched controls. Liver samples were collected from 13 patients with HBV-associated cirrhosis, 23 patients with chronic hepatitis B and 12 healthy controls for immunohistochemical analysis. IL-17 receptor expression was studied on liver biopsies and in human hepatic stellate cells as well as their response to recombinant IL-17 by flow cytometry. Patients with hepatitis B-associated cirrhosis with more severe disease displayed significant increases in peripheral numbers of Th17 cells as well as in IL-17 plasma levels. The increased intrahepatic IL-17(+) cells correlated positively with fibrotic staging scores and clinical progression from CHB to cirrhosis. Moreover, many IL-17(+) cells were located in fibrotic areas in the liver of patients with cirrhosis. In vitro, IL-17 together with IL-17-activated monocytes, could promote the activation of stellate cells, which, in turn, aggravated liver fibrosis and the inflammatory response. In summary, increased peripheral and intrahepatic Th17 cells are enriched in patients with hepatitis B and cirrhosis and contribute further to the severity of disease progression through induction of stellate cell activation.

Abstract
INTRODUCTION We have reported that recipient blood transfusion pretransplant prolongs hepatic allograft survival in rats. This study further investigated the mechanisms of the phenomenon. MATERIALS AND METHODS Male LEW and ACI rats were used as liver transplant recipients and donors, respectively. Experimental animals were divided into control; treatment experimental; and intraportally transfused (1 mL recipient blood) at 7 days before transplantation. RESULTS Rat survival time was significantly longer among the experiment versus the control group. A large number of donor-source dendritic cells were detected among infiltrating cells in the liver and spleen in the experimental group. CONCLUSION We concluded that the prolonged survival of hepatic allograft in these rats was associated with donor dendritic cell proliferation and migration.

Abstract
The effects of heparin-superoxide dismutase (SOD) conjugate (heparin-SOD) on γ-radiation induced DNA damage in vivo and in vitro were evaluated. Plasmid pcDNA3.0 solution was mixed with heparin-SOD, SOD, and a mixture of heparin and SOD (heparin + SOD), respectively, and irradiated with (60)Co at a dosage of 120 Gy. DNA injury was analyzed using agarose gel electrophoresis. The results showed that the degree of injury of pcDNA3.0 mixed with heparin-SOD, SOD, or heparin + SOD was less than that of untreated pcDNA3.0, and among them the degree of injury of pcDNA3.0 mixed with heparin-SOD was the least. It also showed that the protective effect increased with an increase of heparin-SOD concentration. The effects of SOD and heparin-SOD on the DNA damage and tumor inhibition rate of (60)Co γ-radiation exposure on tumor-bearing mice were also studied. Agarose gel electrophoresis showed that, when different SOD samples were administered before irradiation, the thymus DNA injuries of heparin-SOD, SOD, or heparin + SOD groups were more serious than that of the control group, and the DNA injuries of heparin-SOD or heparin + SOD groups were the most serious, which contradicted the above in vitro experiments. However, when heparin-SOD was administered post irradiation, it showed a repairing effect on the injured DNA.

Abstract
Patients with systemic lupus erythematosus (SLE) frequently received corticosteroid therapy, resulting in osteonecrosis of the femoral head (ONFH). Prior studies demonstrated the effectiveness of extracorporeal shockwave treatment (ESWT) for ONFH.. This study evaluated the effectiveness of ESWT for ONFH in patients with SLE. We studied 39 patients, including 15 patients with SLE (26 hips) and 24 controls (29 hips). To each affected hip we applied ESWT (6000 impulses at 28 kV in a single session). Patients were ambulated with partial weight bearing for 4-6 weeks. The primary endpoint was the need for hip replacement. The secondary endpoints were improvement in hip pain and function and image changes on X-ray and MRI. Patients received total hip replacement in 12% of patients with SLE and in 14% of controls (P = 0.802). There was no statistically significant difference in pain scores (0.86 vs. 0.89; P = 0.467) and function scores (89% vs. 91%; P = 0.194) between patients with SLE and controls. SLE response to ESWT for ONFH is comparable with ONFH in patients without SLE.

Abstract
AIMS Aberrant expressions of KL-6 mucin were proved to be associated with worse tumor behaviors of many carcinomas. This study was to evaluate the expression KL-6 mucin, a human MUC1 mucin, in intrahepatic cholangiocarcinoma (CC) and its significance in tumor progression. MAIN METHODS KL-6 mucin expressions in 21 patients with CC, 12 with combined hepatocellular and cholangiocarcinoma (cHCC-CC), and 78 with hepatocellular carcinoma (HCC) were detected by immunohistochemical staining. The effects of two glycosylation inhibitors (tunicamycin and benzyl-alpha-N-acetylgalactosamine (BAG)) on CC cell proliferations were assessed by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide (MTT) assays. KL-6 mucin expressions were detected by immunocytochemical staining and western blotting after tunicamycin or BAG treatment. Cell adhesive and invasive properties were evaluated by adhesion tests and transwell chamber assays after tunicamycin or BAG treatment. KEY FINDINGS Positive KL-6 mucin staining was observed in all CC tissues and CC areas of cHCC-CC tissues. Immunocytochemical staining and western blotting showed that KL-6 mucin expressions were significantly reduced after both inhibitors treatment. Cell adhesive properties were significantly decreased after both inhibitors treatment, while cell invasive abilities were significantly decreased after BAG but not tunicamycin treatment. SIGNIFICANCE This study indicated that KL-6 mucin might be a specific tumor target for CC. Therapeutic strategies that target glycosylation of KL-6 mucin may be useful to control aggressive behaviors of CC.

Abstract
AIMS To determine the effects of the ratios of hyaluronan synthase expression level to precursor sugar UDP-GlcA biosynthesis ability on the molecular weight (MW) of hyaluronic acid (HA) in recombinant Lactococcus lactis. METHODS AND RESULTS The genes szHasA (hyaluronan synthase gene) and szHasB (UDP-glucose-6-dehydrogenase gene) of Streptococcus zooepidemicus were introduced into L. lactis under the control of nisA promoter and lacA promoter respectively, resulting in a dual-plasmid controlled expression system. The effects of the ratios of hyaluronan synthase expression level to the precursor sugar UDP-GlcA biosynthesis ability under different induction concentration collocations with nisin and lactose on the MW of HA in recombinant L. lactis were determined. The results showed that the final weight-average molecular weight () of HA correlated with the relative ratios of HasA (hyaluronan synthase) expression level to the concentration of UDP-GlcA. CONCLUSIONS Regulating the relative ratios of HasA expression level to the precursor sugar biosynthesis ability was an efficient method to control the size of HA. SIGNIFICANCE AND IMPACT OF THE STUDY This study put forward a guide to establish an efficacious way to control the size of HA in fermentation.

Abstract
KL-6 mucin is a type of MUC1 mucin and its aberrant expression has been shown to be associated with aggressive metastasis and poor clinical outcome in tumors. The present study is to investigate the effects of benzyl-N-acetyl-α-galactosaminide (GalNAc-O-bn), an O-glycosylation inhibitor, on KL-6 mucin expression and invasive properties of a human pancreatic carcinoma cell line, Suit-2 cells. Expression profiles of KL-6 mucin in the cells pretreated with or without 5 mM GalNAc-O-bn for 48 h were examined by Western blotting and immunocytochemical staining and invasive properties were examined by transwell chamber assay. Western blotting and immunocytochemical staining showed that the expression profiles of KL-6 mucin changed significantly after GalNAc-O-bn treatment. Meanwhile, the invasive ability of Suit-2 cells decreased significantly after GalNAc-O-bn treatment (p < 0.05). These results suggest that glycosylation of KL-6 mucin may be closely related to aggressive behaviors of pancreatic cancer cells like metastasis and invasion.

Abstract
This article reviewed the process of Traditional Chinese Medicine's modernization on a global scale. This process is motivated by the potential need for traditional medicine as a result of health transitions and increasing drug R&D based on know-how from TCM. The established standards system for modern medicine serves as a basic model yet has limitations in terms of comprehensively evaluating TCM. Spurred by policy committments, research to provide supplements suited to TCM's features and principles is underway. Advanced and interdisciplinary technology and methodology is expected to play an essential role in TCM development.

Abstract
Chemokines are important regulators in the development, differentiation, and anatomic location of leukocytes. The CC chemokine receptor 5 (CCR5) is the receptor for the proinflammatory chemokines and plays an important role in islet allograft rejection. Peptide nucleic acid (PNA) is a nucleic acid analog in which the sugar phosphate backbone of natural nucleic acid has been replaced by a synthetic peptide backbone. Studies indicate that PNA inhibits both transcription and translation of targeted genes. Fullly major histocompatibility complex (MHC)-mismatched murine islet transplant models were used to test the in vivo effect of PNA CCR5 by targeting CCR5 in acute allograft rejection. PNA CCR5-treated recipients demonstrated significant prolongation (12.0 +/- 1.75 days) of functional allograft survival compared with saline (6.5 +/- 0.58 days)- or PNA mismatch-treated recipients (6.5 +/- 0.50 days). The PNA CCR5 blocked the expression of CCR5 in spleen CD3+ T cells. Lymphocytes from PNA CCR5-treated mice exhibited a reduced degree of proliferation comparable to that of saline- and PNA mismatch-treated mice. The present study indicated that PNA CCR5 has a substantial therapeutic effect to inhibit acute allograft rejection.

Abstract
Cu,Zn-superoxide dismutase (SOD) was chemically modified with low molecular weight heparin (LMWH). To characterize the conjugate, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and native polyacrylamide gel electrophoresis (native PAGE) with protein staining and polysaccharide staining were employed. The stabilities of the modified enzyme to heat, acid, alkali, and trypsin treatment were also investigated. SDS-PAGE of the conjugate presented two major bands, and native PAGE of the conjugate showed similar banding position with protein staining and polysaccharide staining, which was different from that of the unmodified SOD and LMWH/SOD mixture. Moreover, the conjugate migrated faster with increasing extent of the modification. Enhanced heat stability, acid resistance, alkali resistance, and anti-trypsin stability of the modified enzyme were observed compared with those of the unmodified enzyme. Results of the study suggest that covalent linkage in LMWH-SOD can be effectively characterized by electrophoretic techniques and the chemical modification of SOD with LMWH can enhance the stabilities of the enzyme. In addition, native PAGE with protein staining can be used to evaluate the extent of the modification.

Abstract
In order to further the present knowledge of the emerging severe acute respiratory syndrome-associated coronavirus (SARS-CoV), 486 different specimens from 54 patients with a clinical diagnosis of SARS were investigated for the presence of viral RNA, and 314 plasma specimens of 73 patients were examined for IgM and IgG antibodies specific against SARS-CoV using an indirect ELISA. Viral RNA was detectable in 28 of the 54 patients tested. Cumulative data showed that 67 of the 73 SARS patients demonstrated seroconversion by week 5 of illness. In contrast, only 1 of 278 healthy subjects enrolled in the study was found to be positive for the IgG antibody. Coexistence of viral RNA in plasma and specific antibodies was simultaneously observed over three consecutive weeks in two critical cases. In three convalescent patients in particular, cultivable SARS-CoV was detected in stool or urine specimens for longer than 4 weeks (29-36 days). These findings suggest that SARS-CoV may remain viable in the excretions of convalescent patients.

Abstract
This longitudinal study investigates the change of erythrocyte complement receptor (E-CR1) expression in patients with severe acute respiratory syndrome (SARS). Circulating E-CR1 expression was semiquantified by flow cytometric analyses in 54 SARS patients and in 212 healthy individuals as a control. Since E-CR1 expression is influenced by the genetic polymorphisms in the CR1 gene, a major genetic polymorphism located within intron 27 of the CR1 gene was simultaneously analysed by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). The results showed that the expression level of E-CR1 (referred to as net fluorescence intensity values, NFI) was statistically correlated with the relevant genetic genotypes among the Chinese population including the healthy individuals (NFI: 5·14 ± 0·82, 3·57 ± 0·66 and 2·67 ± 0·32 for HH, HL and LL genotypes, respectively) and SARS patients (NFI: 3·52 ± 0·91 and 2·63 ± 0·70 for HH and HL genotypes, respectively). Interestingly, the expression density of E-CR1 was found to fall significantly during the initiation and progressive phases (weeks 1 and 2 after the disease onset) and gradually returned close to normal through their whole convalescent phase (beginning from weeks 2 or 3 to weeks 7 or 8) in SARS patients irrespective CR1 genotype. In conclusion, our findings, at least, suggest that E-CR1 is likely involved in immune pathogenesis of SARS disease.

Abstract
BACKGROUND A recently published, population based survey of the Tibet Autonomous Region (TAR) of China reported on low vision, blindness, and blinding conditions. This paper presents detailed findings from that survey regarding cataract, including prevalence, cataract surgical coverage, surgical outcome, and barriers to use of services. METHODS The Tibet Eye Care Assessment (TECA) was a prevalence survey of people from randomly selected households from three of the seven provinces of the TAR (Lhoka, Nakchu, and Lingzhr), representing its three main environmental regions. The survey, conducted in 1999 and 2000, assessed visual acuity, cause of vision loss, and eye care services. RESULTS Among the 15,900 people enumerated, 12,644 were examined (79.6%). Cataract prevalence was 5.2% and 13.8%, for the total population, and those over age 50, respectively. Cataract surgical coverage (vision <6/60) for people age 50 and older (85-90% of cataract blind) was 56% overall, 70% for men and 47% for women. The most common barriers to use of cataract surgical services were distance and cost. In the 216 eyes with cataract surgery, 60% were aphakic and 40% were pseudophakic. Pseudophakic surgery left 19% of eyes blind (<6/60) and an additional 20% of eyes with poor vision (6/24-6/60). Aphakic surgery left 24% of eyes blind and an additional 21% of eyes with poor vision. Even though more women remained blind than men, 28% versus 18% respectively, the different was not statistically significant (p = 0.25). CONCLUSIONS Cataract surgical coverage was remarkably high despite the difficulty of providing services to such an isolated and sparse population. Cataract surgical outcome was poor for both aphakic and pseudophakic surgery. Two main priorities are improving cataract surgical quality and cataract surgical coverage, particularly for women.

Abstract
In clinical medicine, particularly in the newly developing stem cell therapies required to support the practice of regenerative medicine, the measurement of both CD34+ and CD34- hematopoietic stem cells (HSC)/hematopoietic progenitor cells (HPC) is important in obtaining more accurate information about the total HSC/HPC content in various stem/progenitor cell sources. We report the results of an investigation into methods of detecting CD34+ and CD34- HSC/HPC using the immature information (IMI) channel incorporated into the Sysmex XE-2100 and SE-9000 automated hematology analyzers. In this study, CD34+ and CD34- HSC/HPC were separated by immunologic methods and quantified by flow cytometry (FACScan) and IMI channel analysis. In addition, CD34-/CD133+ HSC were prepared by a sequential antibody-based positive selection strategy. These cells appeared in the same area as CD34+ cells in the IMI channel of the automated hematology analyzer. These findings confirmed that an automated hematology analyzer can be used to measure both CD34+ and CD34- HSC. These results may explain the difference in HSC/HPC counts sometimes observed between the automated hematology analyzer and flow cytometric methods for CD34+ measurement. The results of this study demonstrated the potential of automated cell counting methods for measuring HSC content in cellular products for both research and clinical applications.

Abstract
BACKGROUND Public health officials of the Tibet Autonomous Region (TAR) of China requested a survey of blindness, eye diseases, and eye care service utilisation to assist the development of a 10 year blindness prevention and treatment plan. The objective of the survey was to determine the prevalence of blindness and visual impairment, as well as cataract surgical coverage and surgical outcome in the TAR. METHODS The Tibet Eye Care Assessment was a cross sectional prevalence study of three of the seven prefectures (provinces) of the TAR (Lhoka, Nakchu, and Lingzhr) selected to represent its three main environmental regions. The survey sample was selected using a random multistage cluster method. Two teams conducted the survey in a standardised fashion in each prefecture, Lhoka during May and Nakchu during June 1999, and Lingzhr during May 2000. Visual acuity, cause of vision loss, trachoma, and vitamin A deficiency were included in the clinical examination. RESULTS Among the 15,900 people enumerated, 12,644 were examined for an overall response rate of 79.6%. The crude prevalence of blindness (presenting better eye visual acuity of less than 6/60) was 2.3%; age and sex adjusted blindness prevalence was 1.4% (95% CI 1.3 to 1.5). Visual impairment (better eye presenting visual acuity of 6/24 to 6/60) was found in 10.9% (95% CI 10.5 to 11.2) of the population (age and sex adjusted). Cataract was the primary cause of blindness (50.7%), followed by macular degeneration (12.7%) and corneal opacity (9.7%). CONCLUSION Blindness is a serious public health problem in Tibet, with prevalence higher than in similar studies in eastern China. As elsewhere in the world, women have an excess burden of blindness compared to men. About 75% of blindness in Tibet can be either prevented or treated. Eye care planning for Tibet must focus on cataract, particularly among women.

Abstract
The effects of tyrosine kinase inhibitors on the glycine-induced current (I(Gly)) were studied in rat neurons freshly isolated from the ventral tegmental area (VTA). Genistein reversibly and concentration-dependently depressed I(Gly), with an IC(50) of 13 microM. Preincubation with genistein had no effect on I(Gly), indicating that genistein is effective only when glycine is bound to the receptor and channels are most likely open. Genistein depressed maximum I(Gly) without significantly changing the EC(50) for glycine. Genistein-induced inhibition of I(Gly) was sensitive to membrane voltage, being greater at positive membrane potentials. A kinetic analysis indicated that genistein lengthens the time constant of I(Gly) activation, but has no effect on deactivation or desensitization. When genistein was rapidly washed out, a transient rebound current probably reflected a faster dissociation of genistein, with respect to glycine. Results of competition experiments suggest that genistein acts on the same region of the glycine receptor as picrotoxin. Daidzein, an analog of genistein that does not act on protein kinases, also inhibited I(Gly). Co-application of lavendustin A, a specific inhibitor of tyrosine kinase, had no effect on I(Gly). Our results extend to neurons isolated from the VTA, the previous finding that genistein directly inhibits glycine receptors of hypothalamic brain slices.
