Objective To evaluate the imaging exa mination in the diagnosis of periampullary carcinoma. Methods A retrospective analysis of 125 patient s with pathologically proven periampullary carcinomas enrolled in Zhongshan hosp ital between Jan. 1991 and Dec. 2000. Results The accuracy of BUS or CT was higher th an that of ERCP in patients with pancreatic head carcinoma ( P =0.044, P =0. 029, respectively). The accuracy of ERCP was higher than that of BUS or CT in pa tients with duodenal papillary carcinoma ( P =0.005, P =0.03, respectively). The accuracy of ERCP was higher than that of BUS or CT in patients with ampulla ry carcinoma ( P =0.157, P =0.282, respectively). The accurary of MRCP was 8 /8,8/9 respectively in patients with duodenal papillary carcinoma and ampullary carcinoma. Conclusion BUS+CT is the manner of choice in th e diagnosis of pancreatic head carcinoma, ERCP is suitable for nonpancreatic per iampullary cancer. MRCP should be applied widely in the near future.

AIM: To investigate the value and the effect of tripterygium wilfordii on decreasing proteinuria in the primary and secondary nephropathy synd rome in children. METHODS: 30 patients were confirmed the pathol ogy classification, and given tablets of tripterygium wilfordii by 1.5 kg?d -1 for 4 weeks. 24-hour urine volume and gastrointestinal reaction were obser ved, and regularly the 24-hour proteinuria quantity, hepatic and renal function , peripheral blood, and serum albumin were examined. RESULTS: 14 of 30 patients were effective after the treatment, 12 patients were improved, 7 patients were effective after 1-week treatment, and 9 patients were effective after 2 weeks. Individual patients had moderate gastrointestinal disorder; a few patients had modest ALT increase in early therapy; and all recovered after cont inuous treatment. The value of WBC in 3 patients decreased to 3.5 ?10 9 L -1 in the whole course, but, it did not affected the administration. A ll patients had normal renal function. CONCLUSIONS: Tripterygi um wuilfordii can effectively decrease proteinuria, and improve the symptom of primary and secondary nephropathy syndrome in children.

METHODS: 206 cases of AURI were randomly divided into combined group (treating group) and tylenol group. 105 cases in combined group were given XQN orally combined with XSGL, and 101 cases in tylend group were given children tylenol. The treatment of both groups lasted 3 days. RESULTS: The clinical effect in combined group ( 94.3 %) was more than that of tylenol group ( 78.3 %). CONCLUSION: XQN combined with XSGL is both economical and satisfactory in the treatment of children AURI.

Objective To study the strain difference in response to the antidepressant fluoxetine in mouse tail suspension test.Methods Two outbred mouse strains (KM and ICR) and three inbred mouse strains (C57BL/6,Balb/c and DBA/2) were used in this study.They were treated with the selective serotonin reuptake inhibitor (SSRI) fluoxetine or saline and the immobility time in tail suspension test was recorded.Results There was significant difference of baseline immobility time among different stains with C57BL/6 the most immobile((145.0 ±16.8) s) and DBA/2 the least ((34.5 ± 6.1)s).Fluoxetine significantly decreased the immobility time in C57BL/6 ((116.0 ± 10.3) s vs (145.0 ± 16.8) s) of control),Balb/c ((44.3 ± 6.2) s vs (75.3 ± 10.3) s) of control) and DBA/2 mice ((16.6 ± 4.3) s vs (34.5 ± 6.1) s) of control),while the immobile time of KM and ICR mice was not influenced by fluoxetine.Conclusion The effects of fluoxetine in tail suspension test are strain dependent.Fluoxetiue exhibits antidepressant effects in C57BL/6,Balb/c and DBA/2 mice,but not in KM and ICR mice.

Objective To investigate the clinical outcomes of alprostadil in prevention of portal vein thrombosis after splenectomy and devascularization.Methods 113 patients with PHT who were treated with prophylactic alprostadil after splenectomy and devascularization procedures from May 2009 to Apr 2013 were included into the treatment group.112 conservative patients with PHT who were treated with traditional prophylactic anticoagulants after the same operations before May 2009 were included as the control group.The postoperative complication rates,mortality,postoperative drainage volume from the abdominal cavity,blood platelet counts,prothrombin time,liver function,Child-Pugh's scores and portal vein thrombosis rates between the two groups were compared.Results When compared with the control group,the postoperative complication rate and mortality in the alprostadil group were not increased,while the postoperative drainage volume from the abdominal cavity was significantly reduced.The increase in blood platelet counts and prothrombin time were similar in the 2 groups.Furthermore,the extent of hepatic dysfunction on the 3rd and 7th after operation was significantly decreased.On short term follow-up,color droppler ultrasonography showed the portal vein thrombosis rate of the treatment group was significantly lower than the control group,with less extensive degree of thrombosis in the treatment group.Conclusion Alprostadil is a safe and effective anticoagulant which provided better prevention of portal vein thrombosis after splenectomy combined with devascularization.

OBJECTIVE To study the effect of chronic intermittent hypoxia and removal of hypoxia on learning and memory ability in Sprague-Dawley rats and the synaptophysin expression in hippocampus CA3 region.METHODS Experiments were performed on 24 three-month-old male Sprague-Dawley rats,They were randomly assigned to three experimental groups(n=8/group):unhandled control group(UC),chronic intermittent hypoxia group(CIH),and Removal of hypoxia group(RH).Rats in UC group were raised normally,those in CIH group suffered 8H intermittent hypoxia everyday,the duration of experiment was 4 weeks,and those in RH group was treated as same as those in CIH group in the first 4 weeks and were raised normally in the next 4 weeks.The learning and memory ability of rats in each group were assessed with the Morris water maze test at the end of the experiments.The expression of synaptophysin in hippocampus CA3 region was investigated by immunohistochemistry staining and image analysis.RESULTS ①Morris water maze test learning scores(place navigation):From the beginning,the escape latency in CIH rats was significantly longer than that in UC rats and RH rats(P

Objective To obtain high pure myocardiac Troponin T from myocardiac tissue. Methods After the myocardiac tissues were homogenized and purified with high salt solution, the Sephacryl S-300HR column chromatography was employed to separate the cTnT from cardiac proteins, and identified them with SDS-PAGE and Western blot. Results The crude cTn was purified by column chromatography, and there appeared three peaks. The second peak was single component, which could react with mouse anti-human Troponin T antibody, and its molecular weight was about 34kD. Conclusions In this experiment, high pure cTnT was obtained, which could pave a way for further research.

Objective To evaluate the therapeutic approach for patients with periampullary carcinoma (complicated) with acute cholangitis. Methods A comparative analysis of the clinical data of cases of (periampullary) carcinoma with acute cholangitis who were admitted and treated in our hospital during a 12-year period.They included 25 cases who underwent primary resection, and 12 cases who underwent a two-stage resection with initial bile duct drainge. Results After conservative procedures, the preoperative temperature and WBC of patients in primary resection group were much lower than when admitted(P0.05). Total bilirubin and albumin levels showed no significant changes. Compared with the two-stage resection group,the primary resection group had shorter preoperative preparation time, shorter operation time, lesser intra-operative blood loss, but higher postoperative infection complication rate and prolonged length of hospital stay(P0.05). Conclusions Patients with periampullary carcinoma complicated with acute cholangitis can initially be treated conservatively . After biliary infection is controlled, primary (pancreatoduodenectomy) is performed.

Pancreatic sinistral portal hypertension is a localized kind of portal hypertension that usually occurs as a result of the splenic vein obstruction caused by pancreatic diseases.Furthermore,it is also an important cause of upper gastrointestinal hemorrhage.Management in clinical practice should be directed at the sinistral portal hypertension and primary pancreatic diseases.

Objective:To investigate the mechanism of immunoglobulin Y antibodies(IgY) against tumour necrosis factor alpha(TNF-α) and Interleukin-1beta(IL-1β) in treating allergic bronchial asthma through nebulization inhalation.Methods:The allergic bronchial asthma model was established with Hartley guinea pig by ovalbumin nebulizating inhalation.The animals were randomly divided into 4 groups: normal control group(group A)，allergic bronchial asthma group(group B),0.1% anti-TNF-α and IL-1β IgY treating group(group C),1.0% anti-TNF-α and IL-1β IgY treating group (group D).The animals were killed after treatment being accomplished for 2 h,4 h,8 h,24 h and the lungs were made pathological,which were then stained by hematoxylin-eosin(H.E.).The bronchoalveolar lavage fluid (BALF) was collected and the deposited cells were stained by Wright's.Results:①The histological appearance of lung: In group B the histological structure of alveolar ducts and alveolar walls was damaged,the alveolar space was full of transudate and lots of alveolar epithelial cells and leucocytes.The pulmonary interstitial edema,inflammatory cells infiltration,distorted or dilated capillaries and reducing capillary numbers of effective blood stream were observed in alveolar walls.In group C and group D the damage degree of alveolar ducts and alveolar wall was slighter than that in group B and there were few inflammatory cells in alveolar space.In bronchial lumen and pulmonary alveoli the sticky mucus plug was obviously less in group C and group D than in group B.Moreover,inflammatory cell infiltration was seldom observed aroud bronchia,and restoration of bronchial tunica mucosa epithelium was obviously observed in group C and group D.②The cytology appearance of BALF: In group C and group D the numbers of eosinophils,neutrophils,lymphocytes were significantly fewer （2 h,4 h,8 h,P＜0.05）,however,the number of macrophage was significantly more（2 h,4 h,8 h,P＜0.05）than in group B.Conclusion:The anti-TNF-α and IL-1β IgY can obviously alleviate pathological extent of inflammatory reaction in allergic bronchial asthma of guinea pigs by nebulization inhalation therapy.The therapeutic effect of anti-TNF-α and IL-1β IgY between 0.1% and 1.0% concentration is not obvious difference for pathology changes.
