Gossypol has been shown to cause a side effect hypokalemia. This study was designed to evalulated the possible role of gossypol in relation to renal potassium loss by using histochemical method for comparative analysis of gossypol and gentamicin, a well known tubulo-toxic agent, as positive control with respect to nephrotoxic demage in rats and guinea pigs. The results indicated that gossypol had obvious effect on reabsorption function by inducing transitional decrease of membrane enzymes activities of renal tubular cells but had no effect as comparable with gentamicin to cause structureal damage of tubular cells.

[Objective]To investigate the effect of surgical treatment of scapular fractures through posterior approach.[Method]From May 2000 to November 2007,14 patients(10 females,4 males;mean age 34.6 years)with scapular fractures were treated by open reduction and internal fixation through a posterior approach.Eight patients were injurred in traffic accidents,3 due to falling,2 by direct violence and 1 due to cut.There were eleven patients with close fractures and 3 with open fractures.According to Hardegger classification system,there were 8 cases of scapular body fracture,9 of scapular spine fracture,6 of scapular acromion,10 of scapular neck fracture,6 of glenoid rim fracture and 4 of glenoid fossa fracture.[Result]Fourteen patients were followed up,with a mean follow up time of 18 months.According to Rowe score system,10 patients showed an excellent result,2 showed a good result,the other two showed a fair result.[Conclusion]The posterior approach for fixing scapular fractures has advantages of wide exposure,safety,easy operation,and reliable effect.It is a choice of operation for most types of scapular fractures,especially for scapular body fracture,spina scapular fracture and scapular multiposition fracture.

The G protein-coupled estrogen receptor (GPER), also known as G protein-coupled receptor 30 (GPR30), was identified in the recent years as a functional membrane receptor different from the classical nuclear estrogen receptors. This receptor is widely expressed in the cortex, cerebellum, hippocampus, heart, lung, liver, skeletal muscle, and the urogenital system. It is responsible for the mediation of nongenomic effects associated with estrogen and its derivatives, participating in the physiological activities of the body. The present study reviews the molecular structure, subcellular localization, signaling pathways, distribution, and function of GPER in the male reproductive system.

ObjectiveTo evaluate the efficacy and safety of combination therapy of tamsulosin and solifenacin for benign prostatic hyperplasia ( BPH ) with overactive bladder ( OAB ).Methods82 patients with OAB and coexisting BPH were randomly divided into tamsulosin group ( n = 38 ) and combination group ( n = 44). The ages were from 50 to 75 y ( averaged, 56.8 ± 8.6). Inclusion criteria: the mean frequency of micturition ≥8 times per day, the frequency of nocturia ≥2 times per day, voiding volume ＜200 ml each time; for the overactive bladder symptom score ( OA BSS), the 3 rd score ＞ 2, total score ＞ 3. The tamsulosin group accepted tamsulosin 0.2 mg once daily, the combination group accepted tansulouxin 0.2 mg and solifenacin 0.2 mg once daily. Both groups were maintained the corresponding therapy for 12 weeks.The international prostate symptom score (IPSS), Qmax, residual urine volume, OAB score and adverse reactions were recorded.ResultsThe values of IPSS ( 19.5 ±2.2 vs 15.6 ±2.4, P =0.027), the voiding symptom score ( 15.6 ± 2.4 vs 3.4 ± 1. 7, P = 0. 022) and Qmax ( 13.7 ± 3.8 vs 16.6 ± 4.1, P = 0. 034 )improved significantly after treatment in tamsulosin group ( P ＜ 0. 05 ). The values of IPSS ( 19.7 ± 2.3 vs 9.7 ± 3.0, P ＜0. 001), the storage symptom score (13.8 ± 1.9 vs 5.6 ± 1.6, P ＜0. 001 ), OABSS (10.3 ±1.8 vs 5.3 ±1.3, P ＜0.001) and Qmax(14.1 ±4.1 vs 17.2 ±3.5, P=0.027) also improved significantly after treatment in combination group ( P ＜ 0. 05 ). The values of IPSS ( 9.7 ± 3.0 vs 15.6 ±2.4, P ＜ 0.001 ), the storage symptom score (5.6 ± 1.6 vs 12.0 ± 1.6, P ＜ 0.001 ) and OABSS ( 5.3 ±1.3 vs 9.7 ± 2.7, P ＜ 0. 001 ) improved significantly in combination group than those in tamsulosin group ( P ＜0.001 ). There were no difference between two groups in values of the voiding symptom score, Qmax and residual urine volume ( P ＞ 0.05 ). The incidences of adverse reactions in tamsulosin group and combination group were 7.9％ (3/38) and 20.5％ (9/44) without significant difference. There was no acute urinary retention in both groups.ConclusionsIt is effective and safe for patients with BPH and OAB to accept combination therapy of tamsulosin and solifenacin.

Colorectal cancer is currently the third most common cancer worldwide,and there are still half of the patients undergoing recurrence and metastasis after surgical treatment,so it is necessary for colorectal cancer patients to receive radiation therapy routinely.Due to the side effects brought by radiotherapy,it is of great importance to solve how to minimize the radiation dose in radiation therapy and improve radiation sensitivity.In recent years,people discovered that microRNAs can not only be involved in the origins of colorectal cancer and progress,but also play a increasingly important role in cancer radiosensitivity.MicroRNAs can regulate tumor radiosensitivity by influencing tumor microenvironment and function on target genes.DNA damage response caused by radiation includes the activation of ATM,histone modification and chromatin remodeling,cell cycle arrest,damage repair and apoptosis.microRNAs can regulate tumor radiosensitivity through above processes.This review focuses on the mechanism of microRNAs in affecting DNA damage repair and prospects the future of microRNAs in influencing the sensitivity of cancer radiotherapy in clinical application.

Objective To investigate the immunological reaction mechanism of medicated serum in Zibai Gelatin for SiHa cells of the cervical cancer infected by high risk human papilloma virus (HPV). Methods Through immunohistochemical comparison and the cell culture, and after medicated serum was administrated to SiHa cells of cervical cancer for 24 h, 48 h, and 72 h, optical densities of IL-6, IL-10, CD83 and TNF-αin the same time but different concentrations and different times but the same concentration were observed. Relationships of dose-effect and time-effect between expressions of IL-6, IL-10, CD83 and TNF-α and medicine action were analyzed by calculating average optical density. Results With the increase of medicine concentration and administration time of Zibai Gelatin, the expressions of IL-6 and TNF-αgradually decreased, while the expressions of CD83 and IL-10 gradually increased (P<0.05). Conclusion Zibai Gelatin with medicated serum can inhibit local inflammatory reaction by improving local immunologic function of cervix, which is beneficial to reduce cervix high-risk HPV.
