Objective To discuss the diagnosis and surgical management of acute gangrenous cholecystitis (AGC) early after EST and ERCP. Methods Clinical and pathological data of 1468 cases receiving EST and ERCP in our hospital from 2005 to 2007 were retrospectively analyzed. Results AGC occurredin 16 cases and the incidence was 1.09%. Its main manifestations were pain in the right upper abdomen with local pertonitis and fever 1 to 3 d after operation, blood WBC exceeding 15.0× 109/L in 15 cases (93.8%), gallbladder tumefaction and double layer structure by B mode ultrasound, the diagnostic accuracy before operations was 81.3 %. We performed cholecystectomy in 10 cases, cholecystectomy and choledochotomy for common bile duct exploration and stone removal and T-tube drainage in 2, partial cholecystectomy in 3, cholecystostomy in 1. Pathological examination showedthat it was AGC in all the patients. Conclusion Latency in 1 to 3 d, local pertonitis, high blood WBC and B mode ultrasound are main managements in diagnosis of AGC and it should be diagnosed carefully distinguished from perforation and severe acute pencreatitis. It is suggested to undergoing early surgi-cal management once diagnosed definitely.

[ Objective ] To assess the quality of clinical randomised controlled trials (RCT) of traditional Chinese medicine (TCM) for acute myocardial infarction (AMI). [Methods] Eighty - three journals of TCM from the first issues of 1977 to the latest issues of 2002 were manually searched and reviewed under the following inclusion criteria: clinical trials of TCM for AMI with 'randomized controlled or randomised being mentioned. And a questionnaire was designed according to the criteria of RCT with the items of diagnostic standard, consistent of baseline, method of randomization, concealment in allocation, blind method, intention - to - treat analysis, statistic methods and conclusion. Percentages of each item were figured out to assess the quality. [Results] Two thousand five hundred and one trials were associated with heart diseases, among which 102 were associated with AMI and 42 accorded with the inclusion criteria. Calculation method of sample size, concealment in allocation and intention - to - treat analysis after drop - out were mentioned in none of the 42 articles, single - blind method adopted in 4 (9.52%) , diagnostic standard described in 40 (95.24%), baseline consistent illuminated in 27 (64.29%), method of randomization presented in 8 (19.05%) , statistic methods used mistakenly in 6 (14.28%) and statistic methods not described in 18 (42.86%). [Conclusion] There still exist some problems in the design of RCT of TCM for AMI: (1) mistaken use of randomization method; (2) less adoption of calculation method of sample size, concealment in allocation and intention - to - treat analysis after drop - out; (3) improper application of statistic methods; (4) lower rate of utilization for blind study.

Objective To observe the influence of Baicalin and Octreotide on lung injury of rat with severe acute pancreatitis(SAP) and discuss the therapeutic effect and mechanism of the two medicines on SAP.Methods The improved Aho(?)method was adopted to pre- pare SAP rat models via retrograde injection of 3.5% sodium taurocholate to the pancreatic duct.The 135 SAP rat models after being pre- pared were randomly divided into the model group,Baicalin treatment group and Octreotide treatment group with 45 rats in each group;an- other 45 were selected to be the sham operation group which only received abdomen opening surgery.The above - mentioned groups were then randomly divided into 3h,6h and 12h groups with 15 rats in each group.Observed respectively at 3h,6h and 12h after operation,the mortalities of all rat groups followed by batch execution of rats,and then observed the gross pathological and pathological changes of lung. The tissue microarrays technology was applied to prepare the lung tissue microarrays sections.The changes in Bax and bcl-2 protein ex- pression levels of lung tissue of each group were observed via immunohistochemical staining and meanwhile the TUNEL method was applied to observe the lung cell category and apoptotic index changes of lung tissue in each group.Results The 12h survival of model group was 66,67% while those of Baicalin treatment group and Octreotide treatment groups were both 100%,indicating a marked difference(P<0.05).Comparison of lung pathological score disclosed:The model group and Baicalin treatment group obviously exceeded the sham oper- ation group at various time points(P<0.01);at 6h and 12h the Baicalin treatment group was obviously less than the model group(P<0.05)and the Oetreotide treatment group less than the model group(P<0.01).Comparison of Bax protein of lung in each group dis- closed:The Baicalin treatment group and Octreotide treatment group obviously exceeded the sham operation group and model group at 3h (P<0.05),meanwhile the Baicalin treatment group obviously exceeded the Octreotide treatment group(P<0.01).Changes of lung bcl -2 protein expression level of all groups disclosed:The model group and Baicalin treatment group obviously exceeding the sham operation group(P<0.01)as well as the Octreotide treatment group(P<0.05)at different time points,the Baicalin treatment group was obviously less than the model group at 6h(P<0.05).The peak of apoptosis occurred to the Baicalin treatment group at 6h,but statistics showed no obvious difference among all groups at different time points(P>0.05).Conclusions(1)Both Baicalin and Octreotide have protecting effect on SAP lung injury and their therapeutic mechanism is possibly related to apoptosis.The application of tissue microarrays in SAP pathological examination can save manpower and material resources,cut down the experimental cost and improve the experimental efficien- cy,thus worth popularizing.
