RÉSUMÉ

Human platelet lysates(HPL), as a new type of biomaterial, can promote tissue repair, cell proliferation and inflammation control. This paper introduced the development of HPL in the field of regenerative medicine and cell therapy and summarizes their application. The potential of HPL to promote cell proliferation was used as an entry point to show its advantages as a supplement of cell culture medium. Since there is currently no standard procedure for HPL preparation, this paper sorts out the standardization elements such as raw materials source, donor variability and preparation technology, in order to provide reference for the establishment of standards of relevant industry in the future.

RÉSUMÉ

<p><b>BACKGROUND</b>Shang Ring male circumcision (MC) is a safe surgery with good short-term effects. This retrospective study was performed to investigate the long-term result of patients who had undergone Shang Ring MC.</p><p><b>METHODS</b>A total of 103 patients who underwent the surgery were recruited in the study. Before and after the surgery, a questionnaire inquiring sexual function and sexual satisfaction was filled up. Face-to-face interview was executed. Physical examination of the external genitals was performed and complications were evaluated.</p><p><b>RESULTS</b>The median follow-up duration was 19.1 months (range from 9 to 28 months). The mean width of penile mucosa was (9.3 ± 2.5) mm. The mean width of scar was (3.7 ± 1.6) mm. No tender pain was found in participants when palpating the penis. No significant or functional complication was observed except of mucosa asymmetry in one case and scar hyperplasia in two cases. The postoperative sexual function did not differ from the preoperative one, although partners showed better satisfaction toward sexual life.</p><p><b>CONCLUSION</b>Shang Ring MC represents a good long-term cosmetic result with no significant complication or adverse effects on sexual function.</p>

RÉSUMÉ

Objective To detect the treatment effect of PC3 cells with triptolide on altering the expression of genes.Methods MTT assay was used to detec the inhibition of proliferation.Apoptosis was detected by Annexin-V/PI staining.RT-PCR was used to analyze the mRNA expressions of BCL-2,BAX,PIG3,P21,FAS,CASPASE3.Results Triptolide caused a time - and dose - dependent inhibition of cell proliferation,and IC50 of 24 h and 48 h were 18.3 ng/ml and 13.5 ng/ml,respectively.Compared with the 24 h group,the low concentration of triptolide(5 ng/ml,t =1.47,P >0.05)and the high concentration of triptolide ( 160 ng/ml,t =0.91,P >0.05)had no statistical significance in 48 h group,while 10 ng/ml( t =3.26,P <0.05),20 ng/ml( t =4.21,P <0.05),40 ng/ml( t =4.09,P <0.05),80 ng/ml( t =2.91,P < 0.05 )had statistical significance.At the concentration of 18.3 ng/ml,triptolide induced PC3 cells apoptosis in a time - dependent manner.Compared with the control group,Anexin-V( + )/PI(-)was(5.42±2.21)%(t =3.52,P <0.05)in 6h,(13.51±3.37)%(t =6.53,P <0.01) 12h,(29.3 ±4.53)% ( t =8.74,P <0.01) 24 h group separately,and it had statistical significance.RTPCR showed that 18.3 ng/ml triptolide up-regulated the mRNA expression of BAX and PIG3,down-regulated P21 and BCL-2.FAS and CASPASE3 did not show obvious changes.Conclusions Triptolide inhibits the proliferation of PC3 and induces apoptosis,and the changes of BCL-2,BAX,PIG3 and P21 may play an important role in the apoptosis of PC-3 cells.
