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 a practical scientific method for measurement of thyroid remnant in endoscopic thyroidectomy via breast approach.Methods The clinical data of 95 hyperthyroid patients were reviewed and analyzed.The patients were submitted to endoscopic thyroidectomy via breast approach and bilateral subtotal thyroid resection were performed.Thyroid remnant were assessed by naked eyes in 32 cases,thyroid remnant measuring tape in 63 cases.The therapeutic effect was observed.Results All the operations were successfully performed.There was no dyspnea,bleeding,recurrent laryngeal nerve and thyroid gland injury,postoperative recovery was well.The function of thyroid gland was reviewed after operation every 2-3 months,and reviewed by color ultrasound after operation every 6 months.Followed up for 1.8-6.0 years.In 32 patients whose thyroid remnant were assessed by naked eyes,3 patients showed relapse after operation 3 months,2 patients developed hypothyroidism.In 63 patients whose thyroid remnant were assessed by thyroid remnant measuring tape,there had no relapse and hypothyroidism.Conclusion Using thyroid remnant measuring tape in endoscopic thyroidectomy,according to 3.0,2.0,0.5 measurement method,make 1.06 g/cm3 as standard,is scientific,practical and clinical feasible.

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.

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 clinical characteristic of non puerperal mastitis and estimate the effect of anti-mycobacterial agents for non puerperal mastitis .Methods 22 cases of periductal mastitis and gran-ulomatous mastitis receiving anti-mycobacteria drugs therapy from Mar .2012 to Mar.2014 were retrospectively analyzed.Results All patients were female.The mean age was 30 years(ranging from 24 to 46 years).The main clinical manifestation of the 22 patients were 18 patients(81.8%)with mass, 20 patients(90.9%)with abscess, 15 patients(68.2%)with fistula and 9 patients(40.9%)with all of the above 3 symptoms.6 patients had incision and drainage of abscess and 2 patients had tumor resection before anti-mycobacterial therapy .All of the 8 patients had postoperative recurrence .All patients underwent anti-mycobacterial therapy with 3 to 16 months.11 cases (50.0%)patients were cured without recurrence until now .7 cases(31.8%) patients were improved markedly and they still received drug treatment .2 cases(9.0%)patients with tumor size reduced to 2 cm were ready to sur-gical resection.2 cases(9.0%)were lost to follow-up.Conclusion Patients with refractory non puerperal masti-tis can be treated with anti-mycobacterial agents with relatively long treatment time and can also avoid mastecto-my.

Objective To explore the expression of BCSG 1 in the triple negative breast cancer and the non-triple-negative breast cancer and its significance .Methods The clinical data from 170 patients were retrospectively analyzed,which including 160 breast cancer and 10 benign breast disease .We checked the expression of BCSG 1 in the specimens by the immunohistochemistry to analysis the similarities and differences the BCSG 1 between the triple negative breast cancer and the non-triple negative breast cancer .Results The expression rate of the BCSG 1 was 41.0%in the non-triple negative breast cancer , which was lower than 57.5% in the triple negative breast cancer (χ2 =4.2,P=0.04).Conclusion The expression rate of the BCSG1 in the triple-negative breast cancer is higher than that in the non-triple-negative breast cancer.and it was statistically significant (P<0.05),so the expression of BCSG1 in triple negative breast cancer is unique .It prompt that BCSG1 can be a new treatment target in the triple negative breast cancer .

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

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.

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.
