Objective To explore the common complications and methods of treatment in the malignant obstruction of upper alimentary tract with stent insertion. Methods With interventional procedure under fluoroscopic guidance fourteen self expanding stents were implanted in twelve patients, including nine with strictures or obstructions of esophagus, three with obstructions of gastroduodenum. Of the fourteen, nine were coated stents and five were uncoated stents. Results All stents were implanted successfully, but complications after the procedure occurred sometimes. There complications included: 1. Food bolus obstructed in three patients. 2. Chest pain occurred in four patients. 3. Tumour overgrowth or hyperplasia of granulation tissue in three patients caused restenosis of gastrointestinal tract. 4. Stent replacement in three patients. 5. Hemorrhage occurred in two patients (over 300 ml) causing threat to life. Conclusions The implantation of self expanding stent is a simple and effective method offering good palliation for upper alimentary tract obstructions. The complications shoud be treated correctly.

Objective To explore an applicable method for isolation and purification of Cryptosporidium parvum oocysts with high purity, recovery and vigor from mouse feces. Methods Four techniques were used for isolating and purifying C.parvum oocysts from mouse feces: modified saturated saline flotation, percoll gradient centrifugation, CsCl gradient centrifugation and the classical discontinuous sucrose gradient centrifugation. Oocysts received from the methods were used respectively to infect in vitro bovine fallopian tube epithelial cells (BFTE) and the development of the oocysts was examined under microscope after 48 h and 72 h cultivation. Results The number of oocysts received by the classical discontinuous sucrose gradient centrifugation [(2.86?0.08)?107] was significantly higher than that of percoll gradient centrifugation [(1.52?0.08)?107] (P0.05). Oocysts received from CsCl gradient centrifugation showed higher purity than those by discontinuous sucrose gradient centrifugation. Conclusion In comparison to the classical discontinuous sucrose gradient centrifugation, operation of the modified saturated saline flotation is easier and faster, and the purity of oocysts isolated by CsCl gradient centrifugation is higher.

Objective To develop an in vitro culture system for Cryptosporidium parvum in Madin-Darby canine kidney(MDCK) cell and observe its life cycle(from desquamate to oocyst).Methods Oocysts of C.parvum were co-cultured with MDCK cells in vitro.Culture condition was optimized and the life cycle of C.parvum investigated.Results The optimal culture conditions for C.parvum in MDCK cells were 2.0?105 cells cultured for 12 h, and infected by 1.0?105 oocysts in the Dulbecco′s Modified Eagle Medium with 5% FBS.Following 72 h co-culture, desquamate, sporozoites, trophozoites, meronts, microgametocytes, macrogametocytes, zygote, thin-wall oocyst, and thick-wall oocyst appeared orderly.Between the 60th and 72th hour, many oocysts emerged.Inoculated by the C.parvum-infected cell culture supernatant at the 48th hour, the immunosuppressed mice became infected.Conclusion The culture system provides a model for propagation of the parasites and demonstrates a complete in vitro life cycle of C.parvum.

Objective To assess the use of medical services by patients with chronic hepatitis B, cirrhosis resulting from hepatitis, or hepatic carcinoma and the composition of the expenses incurred. Methods A survey was made on the use of outpatient and inpatient services as well as the details of medical expenses incurred by 1 395 self-funded patients and patients enjoying social medical insurance in Shanghai. And an analysis was made on the composition of the expenses and direct medical expenses per annum. Results There was no significant difference between the self-funded group and the insurance group in the use of outpatient and inpatient services; in terms of medical expenses, those incurred by the insurance group were 30% to 50% higher than those incurred by the self-funded group; an analysis on the composition of outpatient expenses showed that drug expenses accounted for over 80% and examination and test expenses accounted for over 15%; an analysis on the composition of inpatient expenses showed that drug expenses incurred by the two groups both accounted for 45% to 60% of the total expenses and examination and test expenses accounted for 15% to 25%. Conclusion Social medical insurance reduces the economic burden of individual patients but significantly raises treatment expenses. The key to containing the rise of medical expenses lies in controlling the conversion of hepatitis B to cirrhosis and the irrational growth of inpatient drug expenses and examination and test expenses.
