OBJECTIVETo explore clinical efficacy of Yiguanjian Decoction (YD) combined Adefovir Dipivoxil Tablet (ADT) in treating HBeAg negative chronic viral hepatitis B (CVHB) active compensated liver cirrhosis (LC) patients.

METHODSTotally 68 HBeAg negative CVHB active compensated LC patients initially treated were assigned to the treatment group and the control group using random digit table, 34 in each group. Patients in the control group took ADT alone, 10 mg each time, once per day. Those in the treatment group additionally took YD, one dose per day. The therapeutic course for all was 48 weeks. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) were detected once in every two weeks. Hepatitis B virus (HBV)-DNA and four items of serum liver fibrosis [procollagen type I (PCN), hyaluronidase (HA), procollagen III peptide (PCIII), laminin (LN)] were detected once per every 4 weeks. Abdominal ultrasound B was performed before and after treatment. The inner diameter of the portal vein and the size of spleen were recorded. The fibrosis degree of liver was evaluated using Fibroscan. Efficacy of Chinese medicine (CM) was evaluated between the two groups before and after treatment using CM syndrome integrals. Efficacy of Western medicine (WM) was also evaluated between the two groups using Child-Pugh grading. Results Compared with before treatment in the same group, ALT and AST levels restored to normal levels, HBV-DNA turned negative (HBV-DNA < or = 1 x 10(2)) in the two groups after 48-week treatment. Besides, levels of TBil, ALB, PCIV, HA, PCIII, and LN obviously decreased (P < 0.05, P < 0.01). Results of ultrasound B showed the inner diameter of the portal vein and the size of spleen decreased. Fibroscan results showed that the elasticity value of the liver obviously decreased (P < 0.05). Besides, post-treatment levels of PCIV, HA, PCEJ, and LN, and the elasticity value of the liver decreased more obviously in the treatment group than in the control group (P < 0.01). There was no statistical difference in post-treatment levels of ALT, AST, TBil, ALB, inner diameter of the portal vein, or the size of spleen between the two groups (P > 0.05). Compared with before treatment in the same group, scores of Chinese medical syndrome and Child-Pugh scores decreased in the two groups after treatment (P < 0.05, P < 0.01). Besides, scores of Chinese medical syndrome decreased more obviously in the treatment group than in the control group (P < 0.05). The effective rate was 8824% (30/34) in the treatment group, higher than that of the control group [67.65% (23/34)] with statistical difference (P <0.05). Conclusion Combined treatment of YD and ADT could significantly improve symptoms of CM and fibrosis degree of liver of HBeAg negative CVHB active compensated LC patients.

OBJECTIVETo observe the protective effects of histone deacetylase inhibitor on stress-induced myocardial injury.

METHODSHealthy male Wistar rats were randomly divided into 3 groups( n = 6), and the stress-induced myocardial injury model was established with chronic restraint stress method. The protective effects of histone deacetylase inhibitor on stress-induced myocardial injury were observed with Trichostatin A (TSA) intervention. Histone acetylation levels in myocardium of rats were detected by Western blot method, spectrophotometry method was used to dynamically determine the activity of rat serum lactate dehydrogenase (LDH), serum creatine kinase isoenzyme-MB (CK-MB) and Caspase 3, and nagar Olsen staining were used to observe the early myocardial damage.

RESULTSRestraint stress could significantly reduce the level of histone acetylation of myocardium in rats, and TSA intervention could inhibit the stress-induced reduction of myocardial levels of histone acetylation. Restraint stress could cause the significant increase of serum LDH activity ( P < 0.05), serum CK-MB activity ( P < 0.05), and the Caspase 3 activity of myocardial tissue (P < 0.05), and early myocardial damage also occurred during restraint stress. ISA intervention could significantly reduce the serum LDH activity (P < 0.05), the serum CK-MB activity (P < 0.05), the activity of myocardial tissue caspase 3 induced by restraint stress (P < 0.05), and the stress-induced myocardial injury was also attenuated by TSA intervention.

CONCLUSIONThe histone deacetylase inhibitor TSA can protect stress-induced myocardial injury.

BACKGROUND:The etiology of anterior cruciate ligament injury remains unclear yet, and some researchers have pointed that interior and exterior factors both contribute to anterior cruciate ligament injury;additionally, the genetic factor interior factors stand out. Collagen genes COL1A1, COL5A1, and COL12A1 are reported to be associated with anterior cruciate ligament injury in Caucasian populations. OBJECTIVE:To investigate the association of polymorphisms of COL1A1, COL5A1 and COL12A1 genes with anterior cruciate ligament injury in Chinese Han population . METHODS:105 patients with anterior cruciate ligament injury were enrolled and 110 patients without history of anterior cruciate ligament injury were as controlls. The first intron rs1800012 in COL1A1, rs127722 and rs13946 in the 3'-UTR region of COL5A1 gene, rs970547 and rs240736 in the 65 and 29 regions of COL12A1 extron were detected and classified by restriction fragment length polymorphism and genetic sequencing technology. RESULTS AND CONCLUSION:rs1800012, rs12722 and rs13946 genotypes, phenotypes and haplotypes in COL1A1 and COL5A1 genes showed no significant differences between groups. rs970547 and rs240736 genotypes as well as phenotypes and haplotypes in COL12A1 also showed no significant differences between groups. However, there was a significant difference in rs970547 gene frequence in male patients between groups. In conclusion, the Sp1 binding site of COL1A1 rs1800012 is not the susceptibility locus of anterior cruciate ligament injury in Chinese Han population. COL5A1 genes rs12722 and rs13946 in COL5A1 are not closely related to anterior cruciate ligament injury. COL12A1 rs970547 and rs240736 have a certain association with anterior cruciate ligament injury in Chinese men. Male individuals with COL12A1 rs970547 A allelicgene and AA genotype are likely to be susceptible to anterior cruciate ligament injury in Chinese Han population.

0.05).CONCLUSION:The excellent mechanical properties of composite ligament can meet the mechanical requirements of appropriate ligament tissue engineering scaffolds.

OBJECTIVETo formulate the classification criteria of disability weight for Alzheimer's disease (AD) and Parkinson's disease (PD) in China and to evaluate the disability weight of AD and PD in population over 60 years old in Beijing.

METHODSBased on the criteria of Global Burden of Disease (GBD), a seven-grade disability classification was used to develop a new disability classification criteria for AD and PD in terms of Delphi method in China. Using the data from epidemiological survey for AD and PD in Beijing in 1997 and new criteria, mean disability weights of AD and PD in population over 60 years old in Beijing were obtained.

RESULTSThe mean disability weights of Alzheimer's disease was 0.40 in population over 60 years old who received treatment in Beijing and 0.52 in those without treatment while the mean disability weights of Parkinson's disease were 0.30 in the patient receiving treatment and 0.23 in those without treatment.

CONCLUSIONDifference between the result of this study and the data of GBD study in the mean disability weight for AD and PD was noticed.

OBJECTIVETo investigate the levels and changes of sexual hormone in serum and seminal plasma, and the epidermal growth factor (EGF), alpha-glucosidase, and fructose in the seminal plasma of non-obstructive azoospermic patients, and to assess the significance of the analysis of their chromosomes.

METHODSThirty-six non-obstructive azoospermic males and 26 normal males were chosen. The results in reproductive endocrine and genetics obtained by radioimmunoassay, colorimetry, and chromosomes G and C banding assay were compared and analyzed to explore into the causes of infertility.

RESULTSThe levels of FSH, LH, PRL and E2 in the serum of the non-obstructive azoospermic patients were higher than those of the control group, but the T level had no significant difference between the two groups. There were no obvious differences in the sexual hormones except in FSH of the seminal plasma. There were 2 cases of abnormal sex chromosomes, 2 cases of big Y chromosomes and 7 cases of small Y chromosomes in the non-obstructive azoospermic patients. No correlation was found between EGF and fructose in the seminal plasma.

CONCLUSIONThe level of sexual hormone in serum, alpha-glucosidase in seminal plasma and abnormal chromosomes might be closely related to non-obstructive azoospermia.

This study examined whether genistein influences the production of nitric oxide (NO) and expression of endothelial nitric oxide synthase (eNOS) and the modulators of eNOS activity in ovariectomized (OVX) rat hearts. Female mature Sprague-Dawley rats were subjected to bilateral ovariectomy, OVX rats were randomly divided into four groups: 17beta-estradiol (0.1 mg/kg, s.c. daily) was used as the positive control; low dose of genistein (0.5 mg/kg, s.c. daily); high dose of genistein (5.0 mg/kg, s.c. daily) and model. Sham operations as controls, the treatment lasted 6 weeks. Blood pressure, heart rate, plasma estradiol, heart and uterine weights were measured. Nitrite production in the myocardium was determined by nitrate reductase method. Protein level of eNOS, caveolin-1 and calmodulin was determined by Western blot. The results showed that nitrite production and eNOS protein in homogenized ventricular tissue was attenuated by approximately 53% and 67% in OVX rats compared with those in sham rats, respectively. Genistein increased nitrite production in rat heart in a dose-dependent manner, genistein at the dose of 5 mg/kg.d(-1) resumed nitrite production to a level similar to that in sham operated rats. Administration of genistein also increased eNOS protein expression in OVX rats myocardium with a concomitant decrease in the expression of caveolin-1, an endogenous eNOS inhibitory protein. Another eNOS stimulatory protein, calmodulin, was unchanged in these treatments. These effects were also observed in rats treated with 17beta-estradiol. Genistein at the dose of 5.0 mg/kg.d(-1) augmented uterine weight but this side effect in reproductive system was less than that of 17beta-estradiol. These results suggest that genistein supplementation and estrogen replacement therapy directly increase eNOS functional activity and NO production in the hearts of the OVX rats, but genistein has less side effects on the reproductive system than 17beta-estradiol.

Purpose: The purpose of this study was to investigate the influences of sex comb on midleg like-2 (SCML2) on hepatocellular carcinoma (HCC) and potentially related mechanisms. Materials and Methods: SCML2 expression in tumor tissues and cells was analyzed using the TCGA database and/or qRT-PCR. The proliferation of HCC cells was detected by CCK-8, colony formation, and EdU assays. The migration and invasion of HCC cells were detected by transwell and wound healing assays. Apoptosis of HCC cells was determined by flow cytometry. Additionally, qRT-PCR and Western blot were used to detect the expression of SCML2 and Wnt/β-catenin/epithelial–mesenchymal transition (EMT) signaling. A xenograft model in mice was established to verify the in vitro findings. Results: We found that SCML2 was highly expressed in HCC tissues and cells and that high expression of SCML2 was correlated with poor prognosis in HCC patients. SCML2 overexpression promoted proliferation, invasion, and migration and repressed apoptosis of HCC cells. The reverse results were obtained in SCML2-silenced cells. Further, we found that SCML2 activated the Wnt/β-catenin/EMT pathway. SCML2 silencing reduced the protein levels of Wnt3a, β-catenin, N-cadherin, Vimentin, and Snail and enhanced E-cadherin protein expression both in vivo and in vitro. Conclusion SCML2 silencing inhibits the proliferation, migration, and invasion of HCC cells by regulating the Wnt/β-catenin/ EMT pathway.
