Objective To understand the effect of circumcision in reducing high-risk human papilloma virus (HPV) infection in male adults. Methods One hundred and twenty-eight married adults with phimosis who underwent circumcision enrolled in the case group and high-risk HPV of urethral discharge specimens were detected before and 2 years after operation. A total of 128 cases of phimosis without circumcision were recruited in the control group. High-risk HPV infection rates were compared between the two groups. Results The highrisk HPV infection rates in the two groups were comparable at baseline. In the circumcision group, high-risk HPV infection rate was 27. 3% preoperative and it significantly decreased to 12.5% two years after operation( x2 =8. 839 ,P =0. 005). In the control group,high risk HPV infection rate was 28. 1% at baseline and it was 25.0%two years later, with no significant difference (x2 =0.320,P = 0.671).Conclusion Circumcision can significantly reduce high-risk HPV infection. Promoting circumcision actively in our country may have an important role in preventing high-risk HPV infection.

Plant growth retardant as one of plant growth regulator can inhibit the cell division, elongation and growth rate in shoot apical meristem (SAM), which can be reversed by gibberellin regulate the product of photosynthesis transfer to the root and rhizome part. As commonly used plant growth retardant, paclobutrazol, uniconazole, chlorocholine chloride, mepiquat chloride, choline chloride and daminozide are used to promote the growth of root and rhizome, call as "zhuanggenling", "pengdasu", "pengdaji" etc. Single or recombination of plant growth regulator is registered as pesticide, and called as pesticide "zhuanggenling" in this paper. Growth regulator which registered as a foliar fertilizer or fertilization was called agricultural fertilizer "zhuanggenling" in this paper. The author investigate the usage of "zhuanggenling" in the root and rhizome of medicinal plants cultivation from 2012 to 2014 in Sichuan province, Huangyuan town, Mianyang (Ophiopogonis Radix); Pengzhou Aoping town (Chuanxiong Rhizoma); Pengshan Xiejia town (Alismatis Rhizoma); Jiangyou Taiping town and Zhangming town (Aconiti Lateralis Radix Praeparata); Yunnan Wenshan (Notoginseng Radix et Rhizoma); Henan province, Wuzhidafeng Town (Rehmanniae Radix, Achyranthis Bidentatae Radix, Dioscoreae Rhizoma); Gansu Min county (Codonopsis Radix, Angelicae Sinensis Radix); Gansu Li county (Rhei Radix et Rhizoma). The result showed that "zhuanggenling" were applied in the most medicinal plant cultivation except Rhei Radix et Rhizoma. It has been applied widespreadly in Ophiopogonis Radix, Alismatis Rhizoma, Achyranthis Bidentatae Radix, Codonopsis Radix; Rehmanniae Radix, commonly in Angelicae Sinensis Radix application, and occasionally in Chuanxiong Rhizoma, Aconiti Lateralis Radix Praeparata, Notoginseng Radix et Rhizoma and Dioscoreae Rhizoma. In 53 collected sample from plantation areas, fifteen (28%) were pesticide "zhuanggenling", thirty-eight (72%) were pesticide "zhuanggenling". UPLC analysis results showed that 38 farmers fertilizer "zhuanggenling" content of 6 kinds of plant growth retardant. It is regarded that fertilizer "zhuanggenling" was dominant in medicinal plant cultivation, and that the plant growth retardant is added widespreadly in farm fertilizer "zhuanggenling". All evidence proves conclusively that "zhuanggenling" have been used in the proper way, whereas some others have been misused or even abused in the use regarding to type, number, use frequency. The root or rhizoma are increased to 20%-200%. But there is lack of evaluation to appraise the quality of medicinal materials from the aspects of research or industry. "zhuanggenling" has become a important Chemical control material besides fertilizer, insecticidal sterilization of pesticide

Objective To evaluate the efficacy of nucleoside analogues (NAs) antiviral therapy on clinical outcome for hepatitis B virus (HBV)-related primary hepatic carcinoma patients after hepatectomy. Methods The clinical data of 156 HBV-related primary hepatic carcinoma patients after hepatectomy were retrospectively analyzed..According to whether accepted postoperative antiviral treatment, all patients were divided into control group (n = 80)and observation group (n = 76). The serum HBV DNA capacity, recurrence-free survival (RFS)and overall survival (OS)were compared between two groups. Results One week, 1 month, 2 months and 3 months after operation , the serum HBV DNA capacity of observation group was significantly lower than that of control group(P < 0.05). One year, 3 years and 5 years after operation, intergroup comparison of RFS rate of both groups showed statistical significance (P < 0.05) and 1 year, 3 years and 5 years after operation, the difference of OS rate of both groups indicated statistical significance (P < 0.05). Conclusion Standard NAs antiviral treatment for HBV-related primary hepatic carcinoma patients after hepatectomy ,can improve prognosis and prolong survival time. The inhibition the HBV copy active may be its mechanism.

Objective To observe the long-term effect of surgical treatment in infertile varicocele patients. Methods 180 infertile patients with varicocele accepted modified Palomo operation (retroperitoneal high ligation of internal spermatic cord vein) from 2004 to 2007, and the long-term effect of thesurgery were analyzed retrospectively, such as semen parameters and spouse pregnancy. Results The operations were performed successfully in 180 cases, and semen parameters improved significantly after the surgery (Ps ＜ 0. 05 ).Among all patients, 10 cases had spouse pregnancy within 3 months after operation;47 cases had spouse pregnancy from 3 to 6 months after operation; 25 cases had spouse pregnancy from 6 to 12 months after operation;13 cases had spouse pregnancy from 12 to 24 months after operation. The fertility rate was 52. 8% (95/180) in total. Conclusion Surgical treatment of infertile male patients with varicocele has good long-term effects, made it the first choice in these patients.

AIM: To investigate the effect of DDP and ADM on cell cycle in leukemia cell line K562. METHODS: The change of cell cycle was observed by means of flow cytometry after different interval in which the K562 cells were treated with DDP and ADM. RESULTS: K562 cells attested at S phase after treated 36 hours with DDP at concentration of 10 ?mol/L or 48 h with ADM at concentration of 1 36 ?mol/L. K562 cells attested at G 1 phase after treated 24 h with DDP at concentration of 20 ?mol/L or at G 2/M phase after treated with ADM at concentration of 0 17 ?mol/L. CONCLUSIONS: K562 cells showed different patterns to change the cell cycle induced by DDP and ADM with different concentrations at different time, which reflected that different checkpoints of cell cycle were activated at different conditions.
