As urine flow dynamic test is widely used in clinical,merge detrusor dysfunction of benign prostatic hyperplasia treatment research also more and more.For normal detrusor contraction force and slight damage (Pdet ＞ 20 cmH2O) of the operative efficacy of BPH patients have reached a consensus of scholars both at home and abroad.For merger severely impaired detrusor contraction force (Pdet 0-20 cmH2O) at odds with the treatment of benign prostatic hyperplasia patients,in combination with related literature,now just urethral catheterization or colostomy,the transurethral resection of the prostate in the same period the bladder again after colostomy,the comprehensive treatment evaluation IⅡ transurethral resection of the prostate surgery and review these main treatment.

Objective To understand the relationship between dietary patterns and breast cancer and to provide a possible scientific basis for breast cancer prevention,we performed a meta-analysis in order to evaluate the current relevant literature.Method Meta-analysis was used to pool the effect of vegetable,fruit,fish and soybean dietary patterns on the risk of breast cancer.The breast cancer risk of the highest categories compared to the lowest categories of such dietary patterns was combined using fixed effect model.Searching the database (Chinese databases included CQVIP,WANFANG medicine online,CNKI and SinoMED,and English databases included PubMed,Embase,Cochrane database,Medline and Google Scholar) for articles published between January 1997 and June 2014.All statistical analyses were performed using the Stata 11.0.Result Twelve cohort studies involving 623 536 participants and 19 707 patients with brcast cancer were found to be eligible.Our results indicate that a reasonably healthy dietary pattern (which is characterized by a high consumption of vegetables,fruit,fish and soybean) is beneficial for the prevention of breast cancer.Compared to the lowest categories of such dietary patterns,relative risk (RR) of the highest categories is 0.86 (95％ CI 0.80-0.92).Conclusion A reasonably healthy dietary pattern (which is characterized by a high consumption of vegetables,fruit,fish and soybean) is beneficial for the prevention of breast cancer.

Objective:To analyze the surveillance data of Kashin-Beck disease (KBD) in Shandong Province, master the changes of KBD, and provide scientific basis for formulating prevention and control strategies of KBD and adjustment of the prevention and control focus of KBD.Methods:According to the requirements of the "National KBD Monitoring Plan" and the "Shandong KBD Monitoring Plan", from 2016 to 2020, the disease monitoring was carried out in the villages of KBD areas in Shandong Province, including the number of clinical positive cases, the number of X-ray positive cases, and the number of metaphyseal positive cases. The detection rate was calculated, and the dynamic changes of the disease was analyzed macroscopically.Results:From 2016 to 2020, a total of 1 816 children aged 7 - 12 years were clinically examined in Shandong Province, and no child with KBD was found. A total of 1 224 children were examined by X-ray, among which 1 positive patient was found in 2016 and 2017, respectively, both of whom were metaphyseal changes, with a total detection rate of 0.16%. There were 367 adult patients with KBD in Shandong Province, including 304 patients with grade Ⅰ, 47 patients with grade Ⅱ and 16 patients with grade Ⅲ. All villages in the KBD areas in Shandong Province had reached the elimination standard, with the elimination rate of 100%.Conclusion:No clinical case of KBD is detected in children aged 7 - 12 years in Shandong Province from 2016 to 2020, which has reached the elimination standard and is in a continuous elimination state.
