Zishi township of Jiangling city is located in the canal area inside embankment,a heavy endemic area of schistosomiasis japonica in Hubei province. The population and cattle preva-lence was 29.5% and 66.7% respectively in 1992. There are 66 canals and it covered a total area of 300000m2. 97.0% of the canals and 99.3% of the total area had snail inhabitants, and 7.6% of the snails distributed in canal was infected which covered 18.3% of the total area. The snails were mainly distributed in the main canal and their branches. The rate of snail distribution was 45.2% and 39.8% respectively. Cattle was pastured all year round in this area. Examination of scattered cattle feces and water revealed that the major factor of water contamination was scattered cattle feces. It explained why the infection rate of snail was high and the distribution of infected snail was extensive and how the major high rise area inside embankment was formed.

Objective:To explore the feasibility, safety and clinical efficacy of ileum augmentation cystoplasty assisted by Da Vinci robot for the treatment of neurogenic bladder.Methods:Retrospective analysis was performed on the data of 12 patients with neurogenic bladder admitted to Zhejiang Provincial People’s Hospital from March 2017 to November 2018, including 11 males and 1 female, with the mean age of 38(12-67). Preoperative symptoms were urinary incontinence, dysuria, decreased bladder capacity, or increased bladder pressure leading to ureteral reflux. All the 12 patients underwent preoperative intermittent catheterization, including 8 patients with spinal cord injury and 4 patients with spinal cord dysplasia. Preoperative serum creatinine(129.58±44.60)μmol/L and total glomerular filtration rate(61.63±18.04)ml/(min·m 2) were observed in 12 patients. Preoperative urodynamic examination showed the safe bladder volume of (95.67±39.10)ml, bladder internal pressure of(63.30±6.02)cmH 2O(1 cmH 2O=0.098 kPa)at the end of filling period, bladder compliance of(10.24±1.14)ml/cmH 2O, residual urine volume of(152.58±80.89)ml, and urine flow rate of(3.88±3.63)ml/s. Bladder contracture was evident on preoperative cystography. Ultrasound examination showed different degree of hydronephrosis and ureter expansion, in all cases, with ureteral reflux grading Ⅰin 2 cases, grade Ⅱ in 4 cases, grade Ⅲ in 4 cases, grade Ⅳ in 2 cases. All the 12 patients underwent robot-assisted ileum augmentation cystoplasty with 5-point puncture. Transverse incision of the bladder wall before full thickness, according to the amount of bladder and quality to decide 30 cm(normal), longitudinal cut back loops and one point after suture fixation in the bladder wall midpoint, fixed point as starting point, in turn, will be blind to the bladder stitching on both sides, the bilateral ureteral placing a single J tube respectively, evaluation of surgical success rate (including intraoperative bleeding, interception of bowel loops are no damage adjacent viscera, ureter openings with and without damage, impermeability, match insufflate whether unobstructed), postoperative complications, anastomotic fistula, intestinal obstruction, abdominal bleeding), urine dynamics test parameters, and patients’ quality of life. Patients were regularly given anticholinergic drugs(2 mg/d) for 6 months after surgery. Results:All the 12 cases in this group were successfully completed without any transfer to open surgery. The operation time was(120.8±12.0)min. Intraoperative blood loss(84.0±23.2)ml. Postoperative intestinal function recovery time(3.3±1.3) d. Postoperative hospital stay(12.1±3.1)d. Postoperative pelvic drainage tube indwelling time (3.8±1.2) d. Catheter and single J tube were removed 2 weeks after operation. Postoperative follow-up averaged 19.4(3-24) months. At 3, 12, 24 months after surgery, the bladder safety volume was rechecked(435.83±33.56), (450.90±31.09), (462.00±33.72)ml, the bladder internal pressure at the end of filling was(18.60±0.92), (15.70±1.42), (12.96±1.34)cmH 2O, the blood creatinine level was(81.43±21.10), (74.34±15.70), (72.90±15.90)μmol/L, and the bladder compliance was(37.94±4.22), (40.40±3.98), (43.42±4.20)ml/cmH 2O and the total glomerular filtration rate(91.52±9.49), (102.18±5.65), (112.41±6.50)ml/(min·m 2) were significantly improved compared with those before surgery( P<0.001). After 24 months of bladder urination training, 1 patient could basically urinate by herself. Three patients were treated with intermittent urinary catheterization supplemented by automatic urination. The remaining 8 patients were completely dependent on urinary catheter for intermittent catheterization. Postoperative complications such as anastomotic fistula, ileus and abdominal bleeding were not found in 12 patients. Conclusions:Ileum bladder enlargement assisted by robot can effectively expand bladder volume, reduce bladder internal pressure, improve bladder compliance, prevent ureteral reflux and protect renal function.

Objective To investigate the relationship of a functional variant (rs72552316)at microRNA-1265 (miR-1265) binding site in toll-like receptor 7 gene and the risk of esophageal cancer.Methods A single center-based case-control study was conducted.In this study,the polymerase chain reaction (PCR) and direct sequencing were used for genotype sequence variants of TLR7 in 204 esophageal cancer cases and 200 controls.The modification of rs72552316 on the binding of miR-1265 to TLR7 protein was measured by Immunohistochemistry assay.Results Individuals carrying the GG genotypes for the rs72552316 were associated significantly with increased risk of esophageal cancer comparing with those carrying wild-type homozygous CC genotypes (OR =2.180,95％CI=1.152-4.127,P =0.019).Furthermore,the expression of TLR7 was detected in the esophageal cancer tissue,suggesting that protein levels of TLR7 might be associated with SNP rs72552316.Conclusion Risk of esophageal cancer was associated with a functional variant at miR1265 binding site in toll-like receptor 7 gene.miR-1265/TLR7 axis may play an important role in the development of esophageal cancer.

Objective To observe the clinical outcomes and safety of continuous negative pressure irrigation (NPI) and endoscopic necrosectomy(ED) for treating infected pancreatic necrosis(IPN). Methods A retrospective review of the data of 163 severe acute pancreatitis(SAP) patients with IPN who were treated by four-step drainage from January 2012 to December 2013 at the SAP therapy center of Nanjing General Hospital was performed. All patients were divided into 7 groups including PCD alone, PCD+NPI, PCD+NPI+ED, PCD+ON, PCD +NPI +ON, PCD +ED +ON and PCD +NPI +ED +ON group based on the drainage strategy of percutaneous catheter drainage(PCD),NPI, ED and open necrosectomy(ON), and the feasibility and safety were analyzed. Results All the patients underwent PCD therapy. Each patient underwent a median of 3 drainage procedures and the median total drainage duration was 11 days. No significant procedure-related complication was observed. Around 40% of the patients recovered after receiving PCD alone. Thirty-four patients(20.9%) underwent ON. The mean hospitalization duration was 38 days and the mean ICU stay was 19 days. There were 25 cases with new-onset organ functional failure,26 patients with sepsis,32 patients with gastric and intestinal fistula,34 patients with intra-abdominal bleeding,8 patients with portal vein thrombosis and 3 patients with gastric outlet obstruction. 28 patients(17.2%) died. Conclusions This four-step approach is effective in treating IPN when compared with other step-up strategies. NPI and ED could offer distinct clinical efficacy without adding no extra risk to patients.

OBJECTIVE: To monitor the changes of plasma asymmetric dimethylarginine (ADMA), nitric oxide (NO), and von Willebrand factor (vWF) levels in patients with stable angina pectoris (SAP) or acute coronary syndrome (ACS) and to evaluate the correlation between ADMA and different types of coronary heart disease. METHODS: A total of 143 subjects were divided into a non-CHD group, a SAP group and an ACS group. Plasma levels of ADMA, NO and vWF were examined and their correlation with SAP or ACS was analyzed. RESULTS: Compared with the non-CHO or the SAP group, ADMA level was elevated in the ACS group (P<0.05). The ADMA level tended to increase in the SAP group compared with the non-CHD group, but had no significant difference (P>0.05). Compared with the non-CHD group, NO level was decreased in both the SAP and ACS group (P<0.05), and it decreased more in ACS group than that in the SAP group (P<0.05); vWF levels were increased in both the SAP and ACS group compared with the non-CHD group (P<0.05). There was no significant difference in the plasma levels of vWF in the SAP and the ACS group (P>0.05). CONCLUSION The change of plasma ADMA level is closely correlated with acute coronary syndrome. ADMA might be a clinical marker for acute coronary syndrome.
