Objective:To study the probable mechanism of HBV effect on cellular immune system in human body by detecting the quantity and function of CD4~+T and CD8+T cells in peripheral blood and liver tisues.Methods:1)The quantity of CD4~+T and CD8~+T cells in peripheral blood was detected by flow cytometry(FCM) in 36 patients with hepatitis B and 20 cases of controls;2)The expressions of HBsAg and HBcAg were detected by streptavidin-peroxidase immunohistochemistry(SP).50 cases of positive HBsAg and(or)HBcAg were selected as HBV(+) group,and 10 cases of negative HBsAg and HBcAg in liver tissue and blood serum were selected as HBV(-) group.The expressions of CD4,CD8,CD25 in liver tissues were detected in the two groups.Results:1)The quantity of CD4~+T cells and the ratio of CD4~+T/CD8~+T in peripheral blood of patients was significantly lower than those in controls;the quantity of CD8~+T cells was considerably higher than that in controls.(2)T lymphoid cell infiltrates in the liver were most gathered in the lobules and the portal tract.The densities of CD8~+T cells were higher in lobules and portal tracts than CD4~+T cells.The quantity of CD8+T and CD4~+T cells in the liver tissues of HBV positive group showed significant difference from the liver tissues of HBV negative group(P~b

Objective:To study the expession of TGF-? 2,TNF-? and its relationship with hepatitis B(HBV) infection in chronic hepatitis B,liver cirrhosis,paratumor cirrhosis and hepatocellular carcinomas(HCC).Methods:HBsAg,HBcAg,TGF-? 2 and TNF-? were detected by immunohistochemical staining among total 63 cases of liver cirrhosis,HCC,paratumor cirrhosis and normal liver tissues.Results:TGF-? 2 and TNF-? were expressed in liver cirrhosis,HCC and paratumor cirrhosis,and they showed significant difference from normal control liver( P c

Objective To investigate the regulatory effect of TNF ? on the expression of plasminogen activator inhibitor 2(PAI 2) and its biological significance. Methods Using immunocytochemistry(ICC), terminal deoxynucleotidyl transferase mediated end labeling (TUNEL) and ICC/TUNEL double label methods, the expression of PAI 2 in and the apoptosis of the cultured epidermal keratinocytes treated by TNF ? were detected. Results After the mouse epidermal keratinocytes were incubated with TNF ?, compared with the unshed cells, the expression of PAI 2 in shed cells and the cellular apoptosis increased obviously. The increased PAI 2 expression also appeared in the apoptotic cells, especially in larger and multi angled apoptotic cells. Conclusion In highly differentiated epidermal keratinocytes, TNF ? can enhance the expression of PAI 2 as well as apoptosis. Furthermore, according to the relation with the keratinocytes apoptosis, there are two types of PAI 2 induced by TNF ?, one of which is related to apoptosis, but the other is not.

Objective To investigate the efficacy and safety of amniotic membrane transplantation in the treatment of severe chemical burns.Methods Amniotic membrane transplantation were performed in 41 patients(41eyes)suffered with severe chemical burns,in which 26 cases were alkaline burns,15 cases were acid burns.Results 41 cases were followed up about 6-24 months,the effective rate were 92.7%,alkaline burns were 92.3%,acid burns were 93.3%.Conclusions Amniotic membrane transplantation is an effective and safe method for the treatment of chemical burns.

24 days in mm, V1:the degree of expansion in ml) had linear correlation, E1=(0.86V1?0.60) mm. Conclusion The results of the study demonstrate that CT is an accurate and reliable imaging technique in the evaluation of the degree of expansion of the injured orbit and in the prediction of the possibility of the consequent enophthalmos and its degree. It is significantly helpful to the therapeutic planning for the quantity the retroglobal filling in the rectification of the enophthalmos.

Objective To explore the efficacy and safety of tenofovir (TDF)+ lamivudine (3TC)+ efavirenz (EFV)combina-tion therapy in the treatment of HBV/HIV coinfection and provide evidence for effective management of HBV/HIV coinfec-tion.Methods All the AIDS/HIV patients treated in our hospital from February 2011 to October 2011 were screened for eligi-bility in this analysis.Twenty eligible patients with HBV/HIV coinfection were treated with the TDF/3TC/EFV triplet regi-men.The efficacy and safety of the combination therapy were evaluated.Results Of the 15 patients who had completed study period of 48 weeks,all had conversion of HBV DNA to negative,2 had HBeAg seroconversion.The liver function tests were normal.HIV-RNA was below the limit of detection in 15 cases.CD4+ increased by 139.72±3.36/μL on average.The creati-nine and lactate levels were within normal limits.No adverse events were reported.Conclusions The TDF/3TC/EFV triplet regimen is safe and effective for treatment of HBV/HIV coinfection.It is appropriate to recommend this regimen as a standard therapy for HBV/HIV coinfection.

Morus alba L. (mulberry) is a well-known deciduous tree, belonging to the genus of Morus of Moraceae famlily. Its leaves, twigs, roots (bark) and fruits are widely used in the traditional Chinese medicine. The active constituents of mulberry contained flavonoids, alkaloids, steroids, coumarins, with the significant hypoglycemic, hypolipidemic, antihypertension, anti-oxidation, anti-inflammatory, anti-bacterial, anti-tumor and immunomodulatory activities. This review summarized the research progress of the major pharmacological activity, pharmacokinetics and drug-drug interaction based on CYPs and transporters of mulberry and its active constituents.

Studies in recent years have shown that the mesenchymal stem cells promote nerve repair and improve neurological function after ischemic stroke.As a major source of mesenchymal stem cells,bone mesenchymal stem cells have potential and broad prospects in the treatment of ischemic stroke.This article reviews the sources,characteristics of mesenchymal stem cells,and the pathogenesis of mesenchymal stem cell transplantation in the treatment of ischemic stroke and prospects.

Clinical work is the core of a hospital. The level of the clinical work and scientific research are the major indexes for the evaluation of a hospital or a clinician. However, there seems contradiction between the clinical work and scientific research. For hospital administration and clinicians, it is important to adopt clinical work as the center, and conduct research around the clinical practice, which will facilitate the transition from the scientific research to clinical application. Eventually the clinical work will improve and medical science will develop.
