【Abstract】Objective To explore the relation between the expression of telomerase and DNA ploidy with biliarypancreatic system cancer, so as to find a better way to diagnose and distinguish jaundice between malignance and benign disease.Methods Endoscopic retrograde cholangiopancreatography (ERCP) were performed before operation in patients with obstructive jaundice. The bile and pancreatice juice were collected before ERCP. Biopsy specimens from part of patients were obtained during ERCP. All cancer specimens were possessed once again during operation and were assessed by the activity of telomerase and DNA ploidy. Results ① Telomerase positive rate 〔87.50%(56/64)〕 of tissue specimens in malignant obstructive jaundice were higher than that in benign obstructive jaundice 〔3.33%(2/60)〕，P=0.000. ② Telomerase positive rate〔71.88%(46/64)〕of Bile and pancreatice juice in malignant obstructive jaundice were higher than that in benign obstructive jaundice 〔3.33%(2/60)〕， P=0.000, tissue specimens obtained by endoscopy with malignant obstructive jaundice had detectable telomerase activity, positive rate was 83.33%（20/24）. ③ The rate of DNA heteroploid with malignant obstructive jaundice was 62.50%（40/64）, that of diploid can be seen in all patients with benign obstructive jaundice, the difference was statistically significant (P=0.000). ④ The rate of telomerase positive and DNA heteroploid in high differentiation tumor were significantly lower than in middlelow differentiation tumor （P=0.028，P=0.001）.Conclusion Applying the duodenoscope we collected the bile and pancreatic fluid before operation and obtain biopsy specimens whose telomerase activity and DNA ploid were detected. This is simple, safe, quick method which can identify the malignant and benign obstructive jaundice.
目的 总结术后早期炎性肠梗阻的临床特点及诊治经验。方法 回顾性分析我院2004年1月至2010年12月期间收治的22例腹部手术后早期炎性肠梗阻患者的临床资料。结果 全组均行保守治疗，均治愈出院。肠梗阻解除时间平均6.5d。2例出院后再次出现慢性肠梗阻，经保守治疗好转。结论 术后早期炎性肠梗阻在腹腔严重感染性疾病术后多见，治疗以保守治疗为主，同时应动态观察腹部症状、体征变化，严防误诊、误治。
Objective To investigate the changes of renal medulla aquaporin 2 expression and morphological changes of epithelia of collecting tube after bile duct recanalizaiton operation. Methods Thirty rats were divided into two groups randomly. Common bile duct ligation was performed on 20 experimental rats with silicon tubes 2 mm in extre-diameter, and sham operation on the other 10 rats. Seven days later, bile duct recanalizaiton was performed on obstructive jaundice group and sham operation on contrast group. Experimental rats were divided into two subgroups randomly. Half of them were killed immediately and the others would be killed 24 hours later. Serum of each rat was collected to detect hepatic function and renal function. Renal medulla was fixed for microscopic examination and was kept in the -80 ℃ refrigerator for aquaporin 2 expression measurement by Western blot technique. Results All of the animals accomplished the experiment smoothly. Golden ascites were found in the rats of obstructive jaundice group. Twenty-four hours after recanalization, serum bilirubin levels decreased 〔(45.95±8.39) μmol/L〕, P＜0.01, and there was no significant change in blood urine and creatine level. Compared with sham operation group (21 966.20±1 544.70), expression of aquaporin 2 decreased significantly after common bile duct ligation in obstructive jaundice group (15 665.30±1 181.85), P＜0.01. After recanalizaion, the expression of aquaporin 2 in obstructive jaundice group increased (19 490.80±4 239.32), P＜0.01. Conclusion Common bile duct obstruction would lead to epithelium injury of renal collecting tube, and down regulate the aquaporin 2 expression.
目的探讨术后早期肠梗阻的临床特点、诊断及治疗。方法对10例术后早期肠梗阻患者进行回顾性分析。结果10例均为机械性肠梗阻。保守治疗6例，其中治愈5例，死亡1例； 手术治疗4例，其中3例术中有绞窄性肠梗阻征象，均治愈。1例术中发现为广泛癌性粘连，行部分粘连松解术，术后第8天再发肠梗阻，保守治疗1天无效，患者自动出院。结论术后早期肠梗阻诊断并不困难； 保守治疗多数有效，故宜先行保守治疗； 可疑肠绞窄时应及时中转手术。
Objective To evaluate the clinical and follow-up results of the surgical treatment for hypertrophic obstructive cardiomyopathy associated with aortic stenosis. Methods We retrospectively analyzed the clinical data of the patients with hypertrophic obstructive cardiomyopathy plus aortic stenosis in our hospital from February 2008 to October 2015. There were 4 males and 3 females aged 55.6 ± 7.5 years. All the patients were received concomitant aortic valvulopasty at the time of modified extended Morrow procedure. Echocardiographic data and major complications were recorded through the outpatient clinic and telephone. Results The postoperative ventricular septal thickness, left ventricular outflow tract gradient and aortic gradient were significantly lower than those in preoperation with statistical differences (P<0.05). During the mean follow-up 25.6 ± 28.2 months period, 1 patient died of cerebral hemorrhage, 1 patient was implanted a permanent pacemaker, and 1 patient had a postoperative new-onset atrial fibrillation. All patients had a satisfied prosthetic valve function and the left ventricular outflow tract gradient. The patient's symptoms and heart function significantly improved postoperatively. Conclusion For patients with hypertrophic obstructive cardiomyopathy associated with moderate to severe aortic stenosis, concomitant aortic valvulopasty at the time of modified extended Morrow procedure is an appropriate and effective treatment, which can significantly alleviate the clinical symptoms, and improve quality of life with a satisfied prognosis.
Objective To explore the surgical management method and outcome of functional univentricular heart with total anomalous pulmonary vein drainage (UVH-TAPVD). Methods We reviewed the surgical procedures and results for 44 UVH-TAPVD patients in our hospital between the year 2010 and 2016. There were 34 males and 10 females. The age of the patients was 312 (77-4 220) d when they accepted the first surgical treatment. Results There were 8 deaths in stage Ⅰ palliation, 1 death in stage Ⅱ palliation and 5 deaths during the follow-up. The overall survival rate was 68.2% (30/44). Glenn operation was undertaken in 34 patients with 5 deaths. Fontan operation was undertaken in 9 patients with 2 deaths. Conclusion Surgical strategies for UVH-TAPVD should be planned according to different anatomical and pathophysiological conditions in different patients. Staged palliations can reduce mortality and morbidity. But pulmonary venous obstruction and heterotaxy syndrome are still risk factors for these patients.

Methods: Seventyone cases above 60 years with Obstructive Colorectal Cancer were analysed retrospectively on their individual accompanied diseases and perioperative treatments, from 2003 to 2008.Results: Fortythree cases of them had suffered from other diseases. Midoperative complications occurred in 19 cases. Postoperative complications occurred in 37 cases. Except 5 cases of death, complications occurring in others cases were well controlled. The death causes mainly were correlated with accompanied chronic diseases. Conclusion: Strengthen care, active management of other chronic diseases are important significantly for senile patients with colorectal carcinoma to get satisfied outcome.
