Background Recombinant hirudin variant Ⅲ(rHV3) can effectively prevent galactose-induced human lens epithelial cells LECs injury,but little is known about the molecular mechanism of its action.Objective The present study was to investigate the effects of rHV3 on the expression of apoptosis-related genes in damaged LECs induced by galactose.Methods The rHV3 was extracted by our research group,and the biological activity of rHV3 was identified by titration of thrombase according to Markwardt's method.Human LECs (SRA01/04) were cultured using 125×10-3 mol/L D-galactose+10% FBS+D/F12 medium to establish the damaged human LECs model.rHV3 was added into the medium of the damaged human LECs model.Human LECs were cultured in D/F12 medium containing 10% FBS as normal control.The expression of apoptosis-related genes,such as aldose reductase (AR),bax,bcl2 and p53,in LECs at the mRNA level was detected using RT-PCR.The abundance ratio of target genes was presented with the absorbance (A) of gene mRNA/GAPDH mRNA.Results Compared to the normal control group,the A values of AR mRNA/GAPDH mRNA,bax mRNA/GAPDH mRNA and p53 mRNA/GAPDH mRNA were significantly elevated in model group (t=3.90E-06,t=8.44E-04,t=5.15E-08,P＜0.01).However,in the rHV3-treated group,the A values of AR mRNA/GAPDH mRNA,bax mRNA/GAPDH mRNA and p53 mRNA/GAPDH mRNA were lower than those of model group (t=5.90E-06,t=1.51E-04,t=3.42E-06,P＜0.01).The bcl2 mRNA/GAPDH mRNA was markedly downregulated in the model group when compared with the normal control group (t=1.86E-05,P＜0.01);while after rHV3 addition,bcl2 mRNA/GAPDH mRNA increased in comparison with the model group (t=8.56E-05,P＜0.01).Conclusion 125×10-3mol/L D-galactose induces the damage and apoptosis of human LECs.rHV3 likely plays a protective function on D-galactose-induced damage of human LECs by inhibiting the polyol pathway and mitochondria-mediated pathway.

Objective: To objectively evaluate the short-term and long-term efficacies of arthrolysis under brachial plexus anesthesia in treating adhesive capsulitis of the shoulder (ACS). Methods: One hundred patients diagnosed with ACS were divided into two groups using the random number method. The two groups both received same active rehabilitation exercises. Besides, 55 cases in the treatment group were given one session of arthrolysis under brachial plexus anesthesia, and 45 cases in the control group were given tuina treatment. Changes in the visual analog scale (VAS) score, Melle score and pressure pain index were observed 1 month and 3 months after treatment. The therapeutic efficacies were also compared. Results: The total effective rate was 96.4％ at the 1-month follow-up and 96.4％ at the 3-month follow-up in the treatment group. The total effective rate was 33.3％ at the 1-month follow-up and 28.9％ at the 3-month follow-up in the control group. There were significant differences between the two groups comparing the total effective rate at the two time points (both P<0.05). The scores of VAS, Melle and pressure pain were significantly different at the 1-month and 3-month follow-ups from those before treatment in the treatment group (all P<0.05); the three scores did not show significant differences at the 1-month and 3-month follow-ups compared with those before treatment in the control group (all P>0.05). Conclusion: Based on the active rehabilitation exercises, one session of arthrolysis under brachial plexus anesthesia can release the adhesion and restore the range of motion and function of shoulder joint in ACS patients. It is superior to rehabilitation exercises plus tuina treatment comparing both short-term and long-term efficacies.

Objective To investigate the effect of low-dose hydrocortisone(HC)on hippocampus nuclear factor kappa B((NF-?B)),I?B expression in lipopolysaccharide(LPS)induced septic rats and the role of NF-?B signal transcription pathway in pathogenesis.Methods Fifty-four rats were randomly divided into 3 groups: control group(A group,n=6),model group(B group,n=24),low-dose HC treatment group(C group,n=24).The septic rat model was established by intraperitoneal injection LPS(1 mg/kg),as the intervention by caudal vein injection low-dose HC(6 mg/kg),each of B and C group was subdivied into 2,8,16,24 hours respectively after LPS injection(n=6).At serial time points,the animals in each group were sacrificed,brain tissue samples were harvested to determine NF-?B,I?B expression by immunhistochemistry in hippocampus.Results In B group: NF-?B expression was up regulated compared with A group(P
