OBJECTIVETo explore the effects of cyclopamine on the proliferation and apoptosis of LNCaP cells and the expression of the PCA3 gene in human prostate cancer in vitro.
METHODSLNCaP cells were treated with cyclopamine at the concentrations of 1, 5, 10 and 15 micromol/L for 24, 48 and 72 hours. The inhibitory effects of cyclopamine on the proliferation and apoptosis of the LNCaP cells were detected by MTT and flow cytometry respectively, the morphological changes of the cells observed by Hoechst 33258 staining, and the expression of the PCA3 gene determined by real-time fluorescence quantitative reverse transcriptase polymerase chain reaction (FQ-RT-PCR).
RESULTSCompared with the blank control group, cyclopamine significantly inhibited the proliferation of the LNCaP cells at 5, 10 and 15 micromol/L (P <0.01), reaching IC50 at 10 micro mol/L at 48 hours. The apoptosis rates of the LNCaP cells at 24, 48 and 72 hours were 37.21%, 57.38% and 57.98% in the 10 micromol/L group and 21. 16% , 71.31% and 72.90% in the 15 micro.mol/L group, significantly different from those in the control (P <0. 01). The cell apoptosis showed a rising trend with the increase of cyclopamine concentration and acting-time, while the expression of the PCA3 gene was decreasing with the increased concentration of cyclopamine, significantly lower than that of the blank control group (P <0.01) , and extremely low in the 10 micromo/L group
CONCLUSIONCyclopamine intervention at 10 and 15 micromol/L for 48 and 72 hours could significantly inhibit the at all time points. Proliferation and induce the apoptosis of LNCaP cells and reduce the expression level of PCA3.

Objective:To observe the clinical effects of acupuncture plus external medicine application for cervical radiculopathy.Methods:A total of 98 patients with cervical radiculopathy were randomly divided into an observation group and a control group based on the random digital table.The observation group (50 cases) was treated by acupuncture plus external medicine application and the control group (48 cases) was treated by acupuncture alone.The patients received the treatment every day.Ten sessions made a course.Cervical spondylosis symptom scale was used to assess the cases before and after the treatment.The clinical efficacy was compared between the two groups after the treatment.Results:The total effective rate was 98.1% in the observation group versus 87.6% in the control group with a statistically significant difference between the two groups (P<0.05).The cure rate was 52.0% in the observation group versus 18.8% in the control group with a significant difference between the two groups (P<0.05).There was no significant difference in the score of cervical spondylosis symptom scale between the two groups before the treatment (P>0.05).It increased with a significant difference in both groups after the treatment (both P<0.05),while a significant difference was found in the results between the two groups after the treatment (P<0.05).Conclusion:Acupuncture plus external medicine application is more effective than acupuncture alone for treating cervical radiculopathy.The method also effectively improves the clinical symptoms.

Objective To discuss the best bacterial combination for the diagnosis of Bacterial vaginosis (BV).Methods This is a retrospective study,230 BV-positive patients and 360 healthy women were enrolled based on the Amsel criteria and Nugent score.5 BV-associated bacteria,including Gardnerella vaginalis,Atopobium vaginae and Leptotrichia/Sneathia species,et al.were amplified by specific-PCR assay,the detection rate were compared between two groups.ROC curve and Kappa test were used to select the best combination.Results The detection rate of Gardnerella vaginalis,Atopobium vaginae,Leptotrichia/Sneathia species,Megasphaera species and Mobiluncus mulieris in BV group (91.3%,83.5%,39.1%,42.6% and 36.5% respectively) were markedly higher than that in healthy women (37.2%,14.4%,11.7%,8.9% and 5.6% respectively),x2 value were 168.848,275.776,60.949,92.886 and 92.68,all P < 0.05.The area under ROC curve of A.vag,G.Vag + A.vag,G.Vag + A.vag + Lepto,G.Vag + A.vag +Mega and G.Vag + A.vag + M.mul were 0.845,0.862,0.865,0.869 and 0.867,and the sensitivity and specifity were higher than 80%,the value of Kappa were larger than 0.75 (P < 0.05).Thus,these five methods were coincident.Conclusion Detection of Atopobium vaginae may be a better way for the diagnosis of BV.

Biosynthesis of fatty acid ethyl ester (FAEE) by genetically engineered Escherichia coli has attracted extensive attentions from scientific community. In this study, we evaluated the effects of thioesterase with different origins on FAEE production and the results show that Cc FatB1 from Cinnamomum camphorum is better than tesA' from E. coli for FAEE production. Then, the optimized FAEE-producing strain KC4, with 21.4 mg/(L x OD600) FAEE production under flask condition and 31.16 mg/(L x OD600) under 5 L fermentation condition, was constructed by co-expression of Cc FatB1 and tesA'. Compared with the reported FAEE-producing strain KC3, KC4 possesses the higher FAEE productivity.
