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.

BACKGROUND:Our previous studies have shown that strontium-doped calcium polyphosphate containing low-dose strontium appears to have a significant effect on angiogenesis-related behaviors of monocultured umbilical vein endothelial cells and osteoblasts.
OBJECTIVE:To investigate the effect of strontium-doped calcium polyphosphate on angiogenesis-related behaviors of umbilical vein endothelial cells and osteoblasts co-cultured, including celladhesion, spreading, proliferation, as wel as the protein secretion of vascular endothelial growth factor and basic fibroblast growth factor from co-culture system in vitro.
METHODS:Human umbilical vein endothelial cells and osteoblastic cells (MG63) were utilized in this study. cells from passage 3 were used for preparation of the cel-scaffold constructs. After placed in 24-wel plate at a ratio of 2:1, human umbilical vein endothelial cells and MG63 cells were seeded onto strontium-doped calcium
polyphosphate, calcium polyphosphate and hydroxyapatite scaffolds and co-cultured for 7 days. The vascular endothelial growth factor and basic fibroblast growth factor protein levels were determined through a double ligand enzyme-linked immunosorbent assay. The colorimetric 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay was performed to quantify the effect of scaffolds on cellproliferation.
RESULTS AND CONCLUSION:Compared with those on calcium polyphosphate and hydroxyapatite scaffolds, cells on strontium-doped calcium polyphosphate scaffolds attached and spread better with a significantly improved cellproliferation. More importantly, the vascular endothelial growth factor and basic fibroblast growth factor expressions were significantly higher in the strontium-doped calcium polyphosphate group than the other two groups (P<0.05), indicating strontium-doped calcium polyphosphate can up-regulate levels of vascular endothelial growth factor and basic fibroblast growth factor proteins.

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.

OBJECTIVE： To confirm the efficacy and safety of latanoprost in treating glaucoma.METHODS： In a double blind， randomized control clinical trial， we compared the efficacy and adverse drug reactions of once daily topically applied 0.005％ latanoprost with those of twice daily 0.5％ timolol for 12 weeks in patients with open angle glaucoma or ocular hypertension.RESULTS： The study included 46 patients（22 pts.randomized to latanoprost treatment， 24 pts.to timolol） ， 46 patients remained at the end of the study.Comparing with baseline diurnal intraocular pressure（IOP） ， the IOP reduction（mean±standard deviation） achieved with latanoprost（7.86±2.39） mmHg， （31.1％， P<0.001），and timolol（6.24±2.58）mmHg （24.9%，P<0.001），the difference between the two groups（1.62mmHg） being significant（P<0.01）. Two patients treated with latanoprost had foreign body sensation. No other ocular and systemic adverse reactions related to the two drugs were found. CONCLUSION: The results of this study demonstrated that 0.005% latanoprost applied once daily is well tolerated and more effective in reducing IOP than 0.5% timolol applied twice daily. Thus, latanoprost has the potential for becoming one of the ideal antiglaucoma drugs.
