[Abstract ] Objective Pelvic radiation disease(PRD) is multiple injuries in more than one organ resulted by pelvic radio-therapy.Patients have the symptoms of frequent feces and fecal incontinence after the resection of small bowel lesion .Sugeries on PRD patients were mainly distal ileum and ilieocecal valve resections , while the most susceptible part of pelvic radiation injury is rectum . However , little research has been done concerning PRD patients′anorectal functions .This study was mainly to evaluate the anorectal function of cervical cancer patients with PRD in order to provide evidence for the therapy and prognosis of PRD . Methods Cervical cancer patients with PRD in need of small bowel resection who hospitalized in our department from January 2014 to January 2015 were collected as patient group , while people from outpatient physical exam group were selected as control group according to the exclusion criteria of hypertension , diabetes, constipation and unrelaxed pelvic floor syndrome .PDR group and control group were matched according to age.All subjects underwent colonoscopy and anorectal manometry .Rectal radiation injury was estimated on the basis of colonoscopy results.Anorectal manometry results of PRD group and control group were analysised statistically . Results PRD group and control group both included 20 women without stenosis or obstruction in rectum .Significant difference was found between PRD group and con-trol group in anal resting pressure (47.23 ±9.08 mmHg vs 58.25 ±9.24 mmHg, P<0.05), anal maximum squeezing pressure (47.23 ±9.08 mmHg vs 58.25 ±9.24 mmHg, P<0.01), anal distension pressure (23.30 ±12.49 mmHg vs 39.10 ±9.99 mmHg, P<0.01), rectal defecation pressure(22.85 ±16,69 mmHg vs 50.90 ±9.14 mmHg, P<0.01) and maximum tolerated rectal volume (112.85 ±51.34 mL vs 173.50 ±48.15 mL, P<0.01).There was no significant difference between the two groups as to the lenghth of functional sphincters(P=0.313),rectum initial threshold(P=0.416) and rectal defecation threshold(P=0.161). Conclusion Ionization radiation that injures PRD patients′internal anal sphincters and external anal sphincters also reduces maximum tolerated rec -tal volumes preoperatively .It′s necessary to assess the muscles and nerve functions of anorectum before intestinal surgery in order to make a proper operation plan which will improve PRD patients′life quality.

Objective To compare the therapeutic effects of 3 operative options with selective high level ligation of spermatic veins, transinguinal canal and renovated Potomo's laparoscopic manage-ment of varicocele. Methods From January 1990 to November 2006, 1075 primary varicocele above grade Ⅱ patients accepted the operations, of them, 685 patients had follow up data and were recruited into this study. These patients were divided into 3 groups according to the operative methods:group A (n=369) was treated with open selective high level ligation of spermatic veins, group B (n=218) was treated with open transinguinal canal operation, and group C (n=98) was treated by renovated Polo-mo's laparoscopic management of varicocele. The complications of the 3 operative methods were com-pared, such as recurrence rate, testicular atrophy rate, scrotal edema rate and semen analysis. The therapeutic effects of these 3 methods were evaluated. Results The recurrence rates of the 3 groups were 3.3%, 7.3% and 5.1%, respectively. Group A had significantly lower recurrence rate than group B, P<0.05. The testicular atrophy rates of 3 groups were 0.5%, 17.9% and 9.2%, respec-tively. There were significant differences among the 3 groups (P<0.05). The scrotal edema rates of the 3 groups were 1.4%, 17.4% and 16.3%, respectively. Group B and C had higher risk of scrotal edema than group A, P<0.05. For patients with ages younger than 30, the improved semen quality rate in group A was higher than in group B and C. The improved semen quality rate in each group of patients younger than 30 was higher than patients with age over 30. Conclusion The open selective high level ligation of spermatic veins is the best choice in the treatment for patients with primary sper-matic varicocele.

Objective To research the effect to the semen quality of the three operation methods of superiority of highly selective varicocele high ligation,transinguinal canal and laparoseopic of renovated polomo management of varicocele.Methods 561 patients in our hospital who charged by infertility had the operation were analyzed retrospectively and were recruited with primary varicocele above grade II for this study.These patients were divided into three group according to three kinds of operation methods of varicocele :group A was treated with highly selective varicocele high ligation and had 300 patients;group B was treated with transinguinal canal operation and had 181 patients; and group C was treated by laparescopic of renovated polomo operation with 80 patients.Through the comparing of the fertility ability of the three operation methods,to evaluate the therapeutic effect of the three methods.Results The increasing rates of the quality of semen in group B was higher than other groups if patients' ages were lower than 30.The increasing rates of the quality of semen in every group was also higher if patients' ages were lower than 30.No difference was found between three groups in natural conception rate (P＞0.05).Conclusion The methods of highly selective varieecele high ligation would be a better choice in the management of patients with primary varicecele because of higher quality of semen.

Objective To understand the potential impact of south-north water transfer project on transmission and distribution of Schistosomiasis japonica, and to put forward the countermea-sures of prevention of the disease transferring into other places. Methods The information on the progress of south-north water transfer project and factors related to the distribution of Schistosoma juponicum were collected, and the suggestions on improving the countermeasures were obtained through the group discussions and field visits. Results The potential impact of the project on the disease transferring is existed, mainly the disease transferring will be through the Lixia River basin in Jiangsu Province, and Chaohu areas of Anhui Province in the east route, and Sihu areas of Hubei Province in the middle route. The snail transferring northward will be affected both by the project and global warming, as a result, the endemic areas of Schistosomiasis will probably transfer into the Hongzehu and Chaohu areas in the future. Conclusion In the east route of the project, if the project is not combined with Schistosomiasis control, the endemic areas of Schistosomiasis will extend into other regions, the loss in the society and economy will be very large.

Objective To investigate the diagnostic value of quantitative detection of α-synuclein and DJ-1 protein in saliva for Parkinson Disease. Methods Twenty seven patients diagnosed with primary Parkinson's disease and 27 healthy controls were studied.The clinical data of all subjects were collected.Each participant received a disease evaluation including Hohn-Yahr stage, unified Parkinson Disease Rating Scale (UPDRS)-Ⅱ / Ⅲ, 12 Item odor identification test from Sniffin'Sticks (SS-12), Montreal cognitive assessment (MoCA), Mini Mental State Examination (MMSE).α-syn and DJ-1 protein in saliva were examined by using enzyme linked immunosorbent assay (ELISA). The statistical analysis was used to test the difference in these two protein levels between patient and control groups and the correlation with age, gender and course of disease. Results There were significant changes in mean concentration of salivary α-syn (1269.02±16.09 pg/mL、1350.51±25.79 pg/mL,P=0.010) and DJ-1 protein (6.07±3.23 ng/mL、8.43±4.33 ng/mL,P=0.027) between patient and control groups. The sensitivity of α-syn and DJ-1 protein levels in PD diagnosis was 55.56% and 77.8%,and the specificity was 89.19% and 55.6%.The area under the ROC curve in finding the PD of α-syn and DJ-1 was 0.671 and 0.649, respectively. In Parkinson disease group, age, gender, UPDRS-Ⅱ / Ⅲ, Hohn-Yahr stage, SS-12, MMSE and MoCA of Parkinson's disease group were not related to the concentration of α-syn and DJ-1 protein in saliva (P>0.05). Conclusion The detection of α-syn and DJ-1 protein levels in saliva may be an auxiliary tool for diagnosis of PD.

Resection is one of the most important treatments for esophageal squamous cell carcinoma, and routine postoperative follow-up is an effective method for early detection and treatment of recurrent metastases, which can improve patients' quality of life and prognosis. This consensus aims to provide a reference for colleagues responsible for postoperative follow-up of esophageal squamous cell carcinoma patients in China, and further improve the standardization of the diagnosis and treatment of esophageal squamous cell carcinoma.
