Objective To study effects of low molecular weight heparin on liver fibrosis and the serum levels of TGF-?_1 in patients with chronic hepatitis B virus.Methods 45 patients with chronic hepatitis B virus were randomized into control group(the routine strategy)and trial group(the routine strategy + low molecular weight heparin).The period of treatment is 3 weeks.Serum hepatic fibrosis indices before and after heparin treatment were examined by RIA,the levels of serum TGF-?_1 before and after heparin treatment were examined by ELISA.Results Hepatic functions became significantly better in trial groups,serum PⅢP and type IV collage levels and the levels of serum TGF-?_1 in trial group decreased significantly after treatment.Conclusions The mechanism of anti-fibrosis action of LMWH may inhibited production of TGF-?_1 in patients with HBV.

OBJECTIVE: To explore the pathogenic variants and clinical classification of two fetuses with Short-rib thoracic dysplasia with or without polydactyly (SRTD). METHODS: With informed consent obtained, the phenotypic characteristics of the fetuses were comprehensively examined, and genomic DNA was extracted from fetal skin tissue and peripheral blood samples of the parents with conventional phenol-chloroform method. Whole exome sequencing (WES) was carried out on both fetuses, and the candidate variants were validated by Sanger sequencing. The pathogenicity of the candidate variants was analyzed using bioinformatic software VarCards, and the impact of the variants on the protein structure was predicted with Swiss-Pdb-viewer. RESULTS: Both fetuses were found to harbor compound heterozygous variants of the DYNC2H1 gene, including c.515C>A (p.Pro172Gln) and c.5983G>A (p.Ala1995Thr) in fetus 1, and c.5920G>T (pGly1974) and c.9908T>C (p.He3303Thr) in fetus 2. The parents of both fetuses were heterozygous carriers. CONCLUSION The compound heterozygous variants of the DYNC2H1 gene probably underlay the SRTD3 in the two fetuses.

Objective:To optimize the processing technology of vinegar-Corni Fructus using Box Behnken design and entropy weight method.Methods:The optimal processing parameters of vinegar-Corni Fructus were optimized by Box-Behnken design. 5-Hydroxymethylfurfural, Nuxaside, Monosanthin, and appearance character were used as comprehensive evaluation indexes. The entropy weight method was used to calculate the weights of each index, taking Design Expert 12.0 for data analysis.Results:The optimal process for vinegar-Corni Fructus as follow: The ratio of excipients was 15%, the simmering time was 2 h, and the steaming time was 8 h.Conclusion:The optimal vinegar-Corni Fructus processing is stable and feasible, which can be used for the production of processed prescriptions.
