Objective To observe the therapeutic effects and complication of combined endoscopic trerapy of the acute biliary pancreatitis(ABP). Methods 70 cases of acute biliary pancreatitis were treated in our hospital in recent 7 years.37 cases(group E) admitted undergone emergency endoscope procedure were treated with endoscopi- cretrograde cholongiopancreatography ( ERCP ), endpscopic sphincterotomy ( EST ) and endoscope naso-biliary drainage(ENBD) in 24h after be hospitalized. 33 cases(group C) were treated with conservation treatment or opera-tion treatment. Results Achievement ratio of endoscopic management was 92 %. There was no severe complication or mortality in group E. The duration of symptoms and hospitalization in endoscopy group were significantly shorter than those in group C(P<0.01). The change of serum and urine amylase was not significant between two groups in the first day after treatment(P > 0.05). But the serum and urine amylase of group E were significantly lower than those in group C in the second day(P< 0.05) and more significantly lower in the third day after treatment(P< 0.01 ). Conclusion Early endoscopic therapy is safe and effective in ABP patients. It is a valuable method to treat a- cute biliary pancreatitis.

Objective To investigate the early diagnosis and rational treatment of traumatic retroperitoneal hematoma(TRPH). Methods Retrospective analysis was done on the clinical data of 96 cases of TRPH admitted in our hospital in the past 10 years. Results Eighty two patients received operation, of whom,73 combined with other celiac organ injuries.The other 14 patients were treated by non surgery.Two patients combined brain trauma and 1 with hemorrhagic shock died during operation,and 2 died of multiorgan failure postoperatively. Conclusions Early diagonsis depends on clinical appearance, abdominocentsis, B ultrasonography and CT. Operation should be done immediately,if the patient has the following condition:(1)apparant hemorrhagic shock after blunt trauma;(2) comfirmed celiac viscera trauma or blood vessel trauma;and (3)retroperitoneal hematoma caused by penetric trauma. Kidney surrounding hematoma or hematoma in pelvis area needs no immediate operation.

Capital logic is the first to be avoided in the construction of medical humane service system,for it is capital logic that manifest the current technical and commercialized time with an "indifferent" characteristic.Capital logic originated and distended from the western culture.As another spiritual pursuit and wisdom,traditional Chinese philosophy provides us with significant ideological resources and helpful revelation for improving medical humane service in current circumstances.

Objective Hepatocyte growth factor (HGF) has been proposed to be used as an endogenous cardioprotective agent. The aim of the present study was to investigate the anti-apoptosis effect of HGF on rat cardiomyocytes after being irradiated by single dose gamma ray. Methods The study was performed using primary cell cultures of cardiomyocytes isolated from hearts of new-born rats. After being cultured for 72h in vitro, cardiomyocytes were irradiated with gamma ray in a single dose of 20Gy. In the HGF treated groups, cells were incubated with HGF in the dose of 20 and 40ng/ml 3h prior to irradiation, respectively. At 48h post-irradiation, the concentration of LDH in the supernatant of cell culture was determined. Apoptosis and cell cycle were determined with flow cytometry. Results LDH concentration in the supernatant of cell culture of irradiated cardiomyocytes was increased significantly compared to that of un-irradiated cells (P

Objective To study the value of microwave coagulation therapy for liver malignant tumors.Methods Under local anesthesia,19 cases with hepatic malignant tumors treated with microwave knife under CT-guided.Results There were totally 23 tumors in 19 cases,13 tumors with≤3.5 cm in diameters were destroyed absolutely after the first treatmet,10 tumors among them were followed-up for 6-12 months and no recurred.10 tumors with＞3.5 cm in diameters treated at multiple points or angle,3～6 months later,CT showed that the tumors were destroyed completely in 6 and mostly in 4,by the hot condensate treatment secondly,3 tumors of 4 were destroyed completely 3 months later.There were no obvious complications.Conclusion The therapeutic effect under CT-guided microwave coagulation therapy for liver tumor which are ≤3.5 cm in diameter of the tumors is very reliable,the tumors＞3.5 cm in diameter can be destroyed mostly or completely by microwave treatment.

AIM:To explore the effects of the new drug of sulfonylurea(1-{4-[2-(3-ethyl-4-methyl-2-oxo-3-pyrroline-1-carboxamido)ethyl]-phenylsulfonyl}-3-(1,4-tetramethylene)-urea,BGW) on the glucose uptake and the activation of Akt/PKB in SMMC7721 cells.METHODS:Cultured SMMC7721 cells were divided into control group,glibenclamide group,insulin group,BGW group and BGW+insulin group.Scintillation was used to detect the glucose uptake in SMM7721 cells.The activation of Akt/PKB was tested by Western blotting.RESULTS:Compared to control cells,gibenclamide,insulin,BGW and BGW+insulin significantly increased the glucose uptake(P

Objective To evaluate the therapeutic effect of duodenoscopy in the early treatment of acute biliary pancreatitis (ABP).Methods Twenty ABP cases admitted from Oct.2000 to Mar.2004 received emergent endoscopic retrograde cholongiopancreatography (ERCP), sphincterotomy (EST) plus endoscopic lithotomy and endoscope naso-biliary drainage (ENBD).Other 16 cases were treated with conservative therapy or open surgery.Results Successful rate of endoscopic management was 95%.There were no severe complications nor mortality in this group.The duration of symptoms and hospitalization in endoscopy group were significantly shorter than control group ( P

Objective To study the relationship of hepatocyte apoptosis and gene expression of liver cirrhosis and primary hepatic carcinoma. Methods Specimens of liver tissue from patients with liver cirrhosis and portal hypertension and normal subjects were examined by transmission electron microscope to detect apoptotic cells and primary cancer gene expression. Results The number of apoptotic cells and the apoptotic index of cirrhotic liver tissue was higher than that of normal subjects.Immunostaining of bcl 2,c myc,c fos was negative in normal liver tissue ,but was over expressed in cirrhosis. Conclusions Hepatocyte apoptosis plays a certain role in the development of hepatic cirrhosis. The oncogenes bcl 2,c myc,c fos take part in the regulation of hepatocyte apoptosis .

Objective To evaluate the therapeutic effect of endoscopic treatment for acute biliary pancreatitis. Methods Thirty-six cases of acute biliary pancreatitis were treated in our hospital in recent 4 years. Tweent cases (group E) underwent emergency endoscopic retrograde cholongiopancreatography(ERCP),endoscopic sphincterotomy(EST) and endoscopic naso-biliary drainage (ENBD) within 24h of hospitalization; 16 cases (group C ) were treated conservatively or by operation. Results Successful rate of endoscopic management was 95.24%. There were no severe complications nor mortality in group E. The duration of symptoms and hospitalization in endoscopic group was significantly shorter than those in group C(P0.05). But the serum and urine amylase in group E were significantly lower than those in group C in the second day(P

PurposeSupport vector machine (SVM) is a machine learning method based on statistical learning theory of Vapnik-Chervonenkis (VC) dimension structure and risk minimization theory. We analyzed the gem spectrum CT scan data of patients with thyroid nodules and established the SVM diagnostic model. The experimental targets were then reduced and the forecast analysis was carried out based on SVM model. The diagnostic model and experimental methods were proved to provide guidance for clinical diagnosis of thyroid nodules.
