Objective To evaluate the therapeutic effectiveness and safety of endoscopic submucosal dissection(ESD)for early colorectal carcinoma and its precancerous lesions. Methods The clinical pathologi-cal characteristics,en bloc resection rate,curative resection rate,complications and follow-up results of 21 pa-tients with early colorectal carcinoma or precancerous lesions,who were treated by ESD,were retrospectively analyzed. Results Most lesions were located in left colon,which accounted for 80. 9%(17/ 21).The most com-mon macroscopic morphology(TypeⅠ)was protrusion type(61. 9%,13/ 21),while flat type was the least (14. 3%,3/ 21). The mean procedure time was 79(35-120)min. The en blot resection rate was 100. 0%(21/ 21),and curative resection rate was 85. 7%(18/ 21). Postoperative hemorrhage occurred in 1 patient (4. 7%,1/ 21)and postoperative infection occurred in 1(4. 7%,1/ 21)and no perforation was recorded. Tubu-lar adenoma with high-grade intraepithelial neoplasia(LGIEN)was the most occurence(33. 3%,7/ 21),villous adenoma with LGIEN was the least(4. 7%,1/ 21). No local recurrence or metastasis was observed during follow-up of 3-20 months. Conclusion ESD is safe,effective,minimal invasive for early colorectal carcinoma and its precancerous lesions,with optimistic prospect of clinical application.

Objective To investigate the correlation between phosphatidylinositol-3kinase(PI3′K)/serine/threonine kinase(Akt)/Forkhead like 1(FKHRL1)signaling pathway and chemoresistance in human gastric cancer cell line SGC7901.Methods From Jan.2004 to sep.2005,cells were exposed to doxorubicin with or without Wortmannin(a special inhibitor of PI3′K/Akt pathway)in Department of Gastroenterology the people's Hospital of when University.Cytotoxicity was assessed by determining cell survival with MTT.By Western blot analysis,the phosphorylation levels of FKHRL1 was evaluated in SGC-7901 cell.Results It was found that doxorubicin caused reduction of cell viability of SGC-7901 and induced phosphorylation of FKHRL1 in a time-dependent manner.Wortmannin enhanced the cell inhibitory efficiency of doxorubicin.Phosphorylation levels of FKHRL1 was significantly induced by Doxorubin in a time-dependent manner and was blocked by wortmannin.Conclusion Doxorubin may activate PI3′K/Akt signaling pathway and then induce phosphorylation of FKHRL1 in a time-dependent manner,which affects the chemoresistance of gastric cancer cell .However,Wortmannin enhances the chemotherapy sensitivity by suppressing this pathway.

Objective:To analyze the rationality of off-label drug use in nephritic syndrome prescriptions to provide scientific basis for clinical rational drug use and further regulate the off-label drug use in our hospital. Methods:Totally 1 908 outpatient prescriptions of nephritic syndrome selected from our hospital during November 2014 to April 2015 were analyzed, and all the off-label drugs were listed . The rationality of the off-label drug use was analyzed and evaluated by searching the related kidney disease guidelines and litera-tures. Results:The off-label drug use of tacrolimus capsules, mycophenolate mofetil capsules, cyclophosphamide for injection, ciclos-porin soft capsules, dipyridamole tablets, hydroxychloroquine sulfate tablets and warfarin sodium tablets were recommended by domes-tic and overseas guidelines with better evidence of evidence-based medicines. Tripterygium glycosides tablets and leflunomide tablets were supported by the literatures on clinical studies at home and abroad. The above 9 kinds of off-label drugs were rational drug use. Lumbrokinase enteric-coated capsules, salvia miltiorrhiza and ligustrazine injection and pidotimod dispersible tablets were reported only by a handful of journals. Bacteria lysate capsules and boric acid powder had no related information support, which belonged to the em-pirical prescriptions of physicians. The above 5 kinds of off-label drugs were not rational drug use. Conclusion:It is a widely existing phenomenon that the medication in nephrotic syndrome is beyond the instruction, the most of off-label drug use are reasonable, and cli-nicians should prescribe medicines carefully. Our hospital needs to further standardize the management of off-label drug use supported by higher evidence in order to improve the level of clinical rational drug use and the reasonable rate of prescriptions.

ObjectiveTo explore the effects of extended nursing intervention (ENI) in nursing ability of discharged patients with intubation of T-tubes.Methods Eighty-two patients with biliary diseases discharged with intubation of T-tubes were equally divided into two groups.The patients in the experiment group were treated with ENI and those in the control group were treated with conventional nursing.Each group received routine nursing and health education before discharge.All patients were followed up by a self-designed written questionnaire.Data regarding patients’ compliance behavior,knowledge of the diseases and satisfaction were collected and analyzed.Result Significant differences were observed between the two groups,the patients in the experiment group exhibiting better compliance behavior,their knowledge of their diseases improved and the rate of satisfaction higher (P<0.05). Conclusion ENI may be effective for the discharged patients with intubation of T-tubes to improve their compliance behavior, enhance their knowledge of their diseases and raise the rate of satisfaction.

Objective To analyze the correlation of acute pancreatitis with hyperlipemia and C reactive pro-tein. Methods 42 patients with acute pancreatitis with hyperlipemia were divided into two groups of SAP group and MAP group under the diagnostic code. The blood fat and CRP were compared between the two groups, also the scores of APACHE Ⅱ , Ranson and CT were measured. Results The CRP and TG in group SAP compared with those in group MAP had significant difference(P<0.01),but the CHOL has no-difference;the scores of APACHEⅡ , Ranson and CT after control lipid in 42 patients were significantly' different( P < 0.05). Conclusion Hyperlipe-mia is one risk factors of the AP;combined with the CRP, it can be one evaluating index of the severity.

Objective To improve the efficiency of donated organs and to investigate the possi- bility and operation protocol of heart and lung transplantation from the same donor to different reci- pients.Methods The organs of heart and lung were obtained from three donors through the method of orthotopic lavage and whole cutting,and transplanted to end-stage patients with heart diseases or lung diseases.First,the donor was subjected to mechanical ventilation,thoracotomy and lavage of heart and lung.The heart and lung were cut in whole and separated.The recipients were subjected the re- trograde lavage of heart and lung.In the patients receiving unilateral lung transcription,the left and right lungs were isolated.Among 3 recipients of lung transcription,one underwent left unilateral lung transplantation and 2 bilateral lung transplantation.Three cases received orthotopic cardiac transplan- tation by using bicaval orthotopic heart transplantation (BOHT) anastomosis method.Results One recipient of left unilateral lung transplantation recovered well after operation.In one recipient under- going bilateral lung transplantation,right upper lung embolism occurred.After re-operation of cutting the right upper lung on the 9th day of the first one,he recovered from the illness.In another recipient receiving bilateral lung transplantation,anastomotic stenosis of trathea and pulmonary infection occurred after operation.After expectant treatment,he recovered from the illness,but died from serious infection 7 months after operation.One of the heart recipients was found having renal failure of first stage,and recovered from disease after hemodialysis treatment.Quality of life was good in all 3 heart recipients after operation and their heart function achieved the restoration of 0-Ⅰstage.Conclusion The treatment protocol of transplantation from the same donor to different recipients at the same time, which can make full use of the organs from donors,is feasible and has good effect.

BACKGROUND:Neural stem cells, as a hot topic in neuroscience research, have a wide application prospect in the treatment of neurological damage, but how to obtain a large number of terminally differentiated and purified nerve cells with homogeneous features is a difficult problem in this field. The use of intracellular fluorescence reporter system to track the process of neural stem cell differentiation and obtain a single kind of terminally differentiated and purified nerve cells provides a viable option. OBJECTIVE: To explore the value of GFAP promoter-driven fluorescence reporter system in tracing the neural differentiation of neural stem cells (NSCs). METHODS: Cerebral cortex of mouse embryos were primarily dissociated and sent for digesting and pipetting mechanically before suspension culture, followed by immunofluorescence staining of Nestin to identify their biological characteristics. Lentivirus carrying pLV/Final-neo-GFAP(promoter)-dTomato vector was employed to infect above-mentioned NSCs, and Geneticin (G418) was used to obtain purified NSCs at 14 days. Subsequently the purified cells were induced to differentiate into astrocyte-like cells; meanwhile red fluorescence changes in cells were observed by microscopy. The red fluorescent cells were then subjected to perform immunofluorescence staining at 13 days after induction. RESULTS AND CONCLUSION:The expression of Nestin in the isolated primary cells was strongly positive. Purified NSCs were obtained by lentivirus infection and subsequent G418 resistance selection at 14 days. After induced into astrocyte-like cells, the red fluorescence was observed in the cells under the microscope and furthermore, GFAP staining was also positive. Mouse NSCs carrying neo-GFAP(promoter)-dTomato were successfully obtained. The cells could express dTomato under the control of GFAP promoter, which provides a powerful tool for research on NSC differentiation mechanism, neural transplantation and tissue engineering product development.
