Objective To evaluate the impact of hepatitis B virus (HBV) genome G1613A and C1653T mutations on disease progression, viral replication capacity, and transcription activity of HBV core promoter (CP). Methods A total of 258 patients were enrolled in the present study, including 65 patients with acute hepatitis B (AHB), 120 with chronic hepatitis B (CHB), and 73 with acute on chronic liver failure (ACLF). Serum HBV DNA was extracted from patients, and full-length HBV genome was amplified by PCR. The incidences of G1613A, C1653T and G1613A+C1653T in different groups were compared, and through functional experiments, the impact of mutants and wild-type virus on viral replication capacity and CP transcription activity was assessed. Results Genotype B, C and D were the three detected genotypes in 285 patients, with detection rates of 22.2%, 76.2% and 1.6%, respectively. The incidences of G1613A, C1653T and G1613A+C1653T mutations increased with the disease exacerbation, and they were 13.70%, 31.80% and 45.20% in AHB patients (P<0.01), 2.30%, 16.30% and 27.40% in CHB patients (P<0.01), and 2.29%, 12.07% and 23.29% in ACLF patients (P<0.05). Compare with wild-type strain, the G1613A mutant strain of HBV increased the viral replication capacity by 6%, reduced HBsAg level and core promoter activity by 15% and 16.2%, and reduced HBeAg to undetectable level; the C1653T mutant strain increased the viral replication capacity, HBsAg level, and core promoter activity by 10%, 55% and 17.1%, respectively, and the HBeAg level was comparable to that of wild-type strain; the G1613A+C1653T mutant strain increased viral replication capacity, HBsAg level and HBeAg level by 7%, 66% and 227%, respectively, while it had no influence on core promoter activity. Conclusion The G1613A and C1653T mutation in CP region may increase HBV replication capacity and alter CP activity and HBV antigens expression, the doublet mutation of G1613A+C1653T shows synergic effect on these changes, suggesting these mutations are associated with liver disease progression.

Objective To identify the effect of long hazardous drinking on cardiovascular function and cardiovascu?lar abnormalities among alcohol dependent patients. Methods A follow-up survey was conducted, 72 potential patients who were diagnosed as having alcohol dependence were recruited into case group and 75 staff who underwent routine health examination were subjected into control group. Furthermore, 52 patients were subdivided into long hazardous drinking group (GroupⅠ) according to the classification of alcohol consumption published by WHO. The rest patients in the case group were considered as not long hazardous drinkers (GroupⅡ). The blood lipid data, echocardiography and ca?rotid artery brachial artery ultrasonography measurement data were compared between the three groups. The high risk fac?tors for cardiovascular abnormalities among alcohol dependence patients were analyzed. And one year after discharge, telephone follow-up method was used to obtain the incidence of cardiovascular accident among patients. Results The dis?tribution of blood lipid data among GroupⅠ, Ⅱ and control group were not significantly different (P>0.05). The LVEF score in GroupⅠwas significantly lower than that in control group (P<0.01). The LAAEF score in GroupⅠwas signifi? cantly higher than that in control group and that in the GroupⅡ(P<0.05). While the FDM and IMT score in the GroupⅠwas significantly lower than that in control group (P<0.01). In the case group, the duration of drinking alcohol was neg?atively associated with LAPEF (r=-0.246, P=0.014) and LAAEF (r=0.239, P=0.016). The average daily alcohol consump?tion was positively associated with LVEF (r=0.256, P=0.010), while negatively correlated with FMD (r=-0.256,P=0.010). Multivariate logistic regression analysis showed that long hazardous drinking was an independent risk factor for cardiovas?cular abnormalities (OR=1.334, 95%CI: 1.060~1.678). Conclusion Long hazardous drinking can reduce left ventricular diastolic and vascular endothelial function. It is an independent risk factor for cardiovascular abnormalities in alcohol de?pendent patient.

Objective The studies on tissue culture and cytological observations of leaf explants of Curculigo orchioides were conducted in order to provide the basis for the rapid propagation of C. orchioides. Methods Young leaf explants of C. orchioides were cultured on MS basal media. Differences in the callus induction and plantlet regeneration rate were observed by different light treatment as well as chemical factors like different phytohormones, casein hydrolysate (CH), and activated charcoal (AC) concentrations. Paraffin method was used to cytological observation. Results For callus induction of leaf explants of C. orchioides, dark treatment gave better results compared to light treatment; among the media tested, the suitable phytohormone combinations were 2.0 mg/L 2, 4-D or 6-BA 1.5 mg/L+2, 4-D 2.5 mg/L, and 300 mg/L CH+0.2% AC was good for plantlet regeneration from leaf explants. The callus from leaf explants mainly originated from midrib. The parenchyma cells near epicuticle of midrib firstly were initiated to division. Then the parenchyma cells of vascular bundle sheath and mesophyll cells on each side of vascular bundle were also divided to form callus. The buds developed on the peripheral parts of the calli, but the roots developed in the regions deep within the calli. Conclusion Tissue culture of young leaf explants of C. orchioides can make the propagation of C. orchioides rapid.

Objective To assess the feasibility of heterogeneous acellular dermal matrix(ADM)seeded with adipose derived stem cells(ADSC)for urethroplasty in a rabbit model.Methods ADSC were isolated from a rabbit and expanded in vitro,then identified by flow cytometry.We seeded ADSC onto the ADM and made it into tissue-engineered urethra.12 male rabbits were removed 1 cm urethra and divided into experiment group and control group.There were 6 rabbits in each group.Reconstructed urethra with tissueengineered urethra was used in experiment group,while unseeded ADM were used in control group.Urethrography was performed at 6 months after surgery.The animals were scarified at 3 and 6 months after surgery and the repaired urethra were harvested.H&E staining and immunohistochemical staining were performed with cytokeratin AE1/AE3 and smooth muscle desmin makers.Results The morphology of isolated ADSC was with long spindle cross-links,and had multicentral growth.Flow cytometry showed that the ADSC expressed CD166,CD105,CD90 and CD44,but not expressed CD45 and CD13.The cells could growth well on the ADM and showed good biocompatibility with it.All animals could void normally,urethrography showed there was no significant stenosis.3 months after surgery,the experiment group appeared regenerated smooth muscle but not in the control group,both groups did not regenerate urothelium.At 6 months urothelium and smooth muscle cells could be observed in the experiment group,but only the smooth muscle was evident in the control group.Conclusions By applying tissue engineering methods,we can seed the ADSC onto the heterogeneous ADM and make it into tissue-engineered urethra,which can help improve the reconstructive effect of urethra.

Background and purpose:It has been reported that gap junctional (GJ) function was signiifcantly decreased in hepatocellular carcinoma (HCC) tissues and cell lines. However, the increased GJ suppress tumorigenesis and the development of liver cancer. This study therefore aimed to examine the effect of simvastatin on GJ function between Hep3b cells. Thus, the exploition of drugs to increase GJ function between liver cancer cells will provide an efifcient approach to ifght against liver tumor as well as increase cytotoxicity of antitumor agents.Methods:SRB was used to assay the toxicity of simvastatin. The effect of simvastatin on GJ function was determined by “Parachute” dye-coupling assay and scrape loading/dye transfer assay.Results:Pretreated Hep3b cells with simvastatin at the concentration of 1, 5 or 10 μmol/L for 24 h did not induce the cytotoxicity. So simvastatin at the concentration of 5 and 10 μmol/L would not reduce the amount of GJ on cell membranes. “Parachute” dye-coupling assay showed that the treatment with 5 and 10 μmol/L simvastatin for 4 h enhanced the dye spread through GJ in Hep3b cells. Similarly, scrape loading/dye transfer assay showed that simvastatin could induce the increasing spread of lucifer yellow (Ly, Sigma) around the scoifng cells with increasing concentrations.Conclusion:Simvastatin could increase the GJ function of Hep3b cells.
