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.

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 prepare and identify the mouse anti-human monoclonal antibodies ( mAbs) using leukocytes as im-munogens. Methods: The mice were immunized using human peripheral blood leukocytes. Then, use of B lymphocyte hybridoma technology preparation of mAbs,followed screening by immunocytochemistry and limited dilution. The secreted mAbs were identified by immunoprecipitation,mass spectrometry,Western blot,ELISA and immunohistochemistry. Results:The 35 positive polyclonal cells were obtained,of which 11 strains secreted mAbs against S100A9. And one strain was used to prepare monoclonal antibody. The purified mAb against S100A9 were purified and identified as IgG1 subtype,with the titer,purity and affinity constant was 1∶3. 18×105,95% and 3. 54×108 L/mol,respectively. This mAb generally had 0. 12% crossed reactivity to S100A8 ,and showed little or no cross reactivity to S100A12 and S100A13. The prepared monoclonal antibodies can specifically recognizes the S100A9 antigen in human breast cancer tissues. Conclusion:Successful preparation of mAb against S100A9,which can secrete specific mAb against S100A9 protein with high titers and specificity have been established successfully,which laid the foundation for the immunology application.

Objective:To explore the differences in intravascular ultrasound results in elderly coronary heart disease(CHD)patients with different uric acid levels.Methods:A total of 145 elderly patients diagnosed with CHD in our hospital from December 2017 to May 2020 were included as study subjects.Uric acid levels were measured and intravascular ultrasound examination was conducted in all patients.They were divided into different groups based on uric acid levels: Group A(uric acid≤199 μmol/L), Group B(uric acid 200~399 μmol/L)and Group C(uric acid≥400 μmol/L). Data from intravascular ultrasound-derived indexes were analyzed and compared between the three groups.Results:There was no significant difference in the degree of left main stenosis between Group A and Group B, but it was less severe in both groups than in Group C( F=5.625, P=0.039). Plaque fibrous cap thickness showed no significant difference between Group B and Group C, but it was smaller than in Group A( F=7.825, P=0.020). Group C had the largest plaque area and maximum thickness among the three groups, followed by Group B[(11.12±1.73)mm 2 and(1.76±0.24)mm]and Group A[(8.29±3.14)mm 2 and(1.38±0.09)mm]( F=6.384 and 6.827, P=0.028 and 0.015). Conclusions:Elevated uric acid levels in elderly CHD patients can increase the area and thickness of plaques, and reduce plaque fibrous cap thickness, leading to an increased risk of formation of unstable plaques, which can be life-threatening for these patients.Thus, monitoring and managing uric acid levels should be stressed in elderly CHD patients.
