Objective To evaluate the effect of captopril in treatment of acute pancreatitis and its influence on serum C reactive protein ( CRP) .Methods 100 cases of acute pancreatitis patients were randomly divided into the control group and observation group,50 cases in each group.The control group was treated with fasting,gastroin-testinal decompression,somatostatin, anti-inflammatory and other conventional treatment, while the observation group was given captopril on basis of routine treatment,the effective rate after 7 days of treatment,pain relief time,amylase returned to normal time,pancreatic edema improved time,serum CRP before and after treatment were compared be-tween the two groups of patients.Results The effective rate after 7 days of treatment of the observation group was 86%,which was significantly higher than 72%of the control group(χ2 =7.334,P<0.05);The pain relief time,am-ylase returned to normal time,pancreatic edema improved time of the observation group after treatment were (1.75 ± 0.44)d,(3.49 ±1.22)d,(7.50 ±2.39)d,respectively,which of the control group were (2.25 ±0.58)d,(4.25 ± 1.59)d,(9.25 ±2.87)d,respectively,there were statistically significant difference between the two groups(t1 =3.55,t2 =4.18,t3 =8.33,all P<0.05);the serum CRP level of the observation group after treatment was (10.39 ± 3.66)mg/L,improved obviously compared to (25.46 ±8.33)mg/L of the control group,the differences between the two groups was statistically significant(t=11.45,P<0.05).Conclusion Captopril has a good effect in treatment of acute pancreatitis,which can effectively improve the level of serum CRP.

Twenty six patients with liver cancer who received liver transplantation were enrolled in the study. The patients were assessed by SF-36 scale and QOL-LC V2.0 scale before and 0 -6, 7 - 12, > 12 months after the liver transplantation. Scores in physical function domain and social function domain decreased significantly in the early stage post LT (0 -6 month post-LT). While in later stage ( >7 months post-LT), the scores showed no significant difference or even higher than that of pre-LT. In psychological function domain, no significant difference was found pre- and post-LT. The scores were improved significantly in later stage post-LT than pre-LT and early stage post-LT.

Objective To explore the adiponectin expression in the chronic hepatitis B (CHB) patients and compare the level of edipanectin before and after antiviral therapy, and investigate the relationship between ediponectin and CHB. Methods Serum adiponectin was detected by enzyme linked immunosorbent assay (ELISA), and the expression of adipanectin in liver tissue was detected by palymerase chain reaction (PCR) and immunohistochemistry. The liver functions and HBV DNA were also tested. Liver biopsy tissue was assessed by fibrosis stage. Results Serum adipanectin in CHB liver cirrhosis [(20.65 ± 1.29) mg/L]was higher than that in other stage fibrosis, the values were (8.57 ± 0.28 ), (12.22 ± 0.64), (15.22 ± 0.77 ) mg/L (P< 0.01 ). Serum adiponectin was positively associated with fibrosis stage(r = 0.976,P< 0.01 ). There was no significant difference between HBV DNA and ALT (P> 0.05 ). Serum adipanectiu was independently associated with liver cirrhosis (r = 1.07, P = 0.02, 95% CI = 1.00-l.14).At the end of antiviral therapy,the expressions of adiponectin declined in patients with improved fibrosis and sustained viral response. Conclusion Serum adiponectin may play a role in CHB fibrosis, and reduced adipanectin level is associated with improved fibrosis after antivital therapy.

Objective To study the effect of implanted stent or selected operation in patients with acute occlusion of right coronary artery during the emergency coronary arteriongraphy. Methods Forty-three patients with acute occlusion of right coronary artery who underwent the emergency coronary arteriongraphy were divided into two groups: the implanted stent group ( n = 23) during the emergency coronary arteriongraphy and the selected operation group (n =20) during the emergency coronary arteriongraphy . Then we observed the general data, the coronary artery pathological changes, preoperative and postoperative thrombus, the blood flow, remained stenosis and the prognosis. Results The implanted stent group was similar to the control group in general condition, but implanted stent group was significantly different from the control group in the near, intermediate and distal coronary artery pathological changes ( <0.05) . The control group was significantly different from the implanted stent group in the thrombus and slowly blood flow ( <0.05) . After three months, we reviewed coronary arteriongraphy and selected operation, The implanted stent group was significantly different from the control in the remained stenosis and slowly blood flow (<0.05) . But the implanted stent group was similar to the control groug in the thrombus and new proceeding cardiovascular events. Conclusion When thrombus appears in acute occlusion of right coronary artery, we can implant stent during the emergency coronary arteriongraphy if the thrombus is little, or we can select operation after PTCA on the contrary.

BACKGROUND:Many studies have demonstrated that FirebirdTM and Taxus Express2TM can effectively reduce intrastent restenosis.However,there are few data about long-term efficacy of two stents,and reports about middle and long-term follow up are rare.OBJECTIVE:To observe the safety and biocompatibility of FirebirdTM and Taxus Express2TM in percutaneous coronary intervention(PCI) for coronary artery disease.DESIGN,TIME AND SETTING:Non-randomized concurrent control clinical observation was performed at Department of Cardiology,Hongqi Hospital of Mudanjiang Medical College from April 2005 to April 2008.PARTICIPANTS:233 patients(268 lesions) undergoing PCI were divided into FirebirdTM(n =82),Taxus Express2TM group(n =80) and bare metal stent group(n =71).METHODS:Coronary arteriography was performed through femoral artery or radial artery.Vascular inner diameter was determined using quantitative computer analysis.The patients underwent FirebirdTM,Taxus Express2TM and bare metal stenting,respectively.The patients were reexamined and followed-up using telephone every 2-4 weeks after discharging and examined using coronary arteriongraphy after 9-12 months.The follow-up lasted for 24 months.MAIN OUTCOME MEASURES:Characteristics of arteriongraphy and stenting condition of all patients;biocompatibility of stent to host;major adverse cardiac events during hospitalization and follow-up,including death,angina pectoris attacks or heart failure;coronary artery diameter decreased ≥ 50% was regarded as restenosis.RESULTS:101 stents were implanted in Firebird group,98 in Taxus Express2 group and 85 in bare metal stent group.There was no stent defluxion,dislocation,or breakage.No noticeable platelet decrease,hemolysis or white blood cell increase was found.There were no significant differences among three groups in terms of Characteristics of arteriongraphy and stenting condition.The incidence of major adverse cardiac events and intravascular restenosis in Firebird and Taxus Express2 groups was fewer than bare metal stent group(P 0.05).CONCLUSION:No specific biocompatibility responses in treatment of coronary artery diseases using FirebirdTM and Taxus Express2TM.The two drug-eluting stents are superior over bare metal stent in reducing restenosis.The safety and efficacy of two drug-eluting stents are similar.

Objective To investigate the clinical manifesfations and diagnostic and therapeutic features of cholangiocarcinoma associated with hepatolithiasis.Methods The clinical data, the diagnotic and therapeutic featares of 54 cases of cholangiocacinoma associated with hepatolithiasis were retrospectively analyzed.Results The occurrence rate of hepatolithiasis concomitant with hepatocholangiocarcinoma was 11.8%.Due to a lack of specific clinical manifestations, the preoperative diagnosis of this condition was difficult. In this series, the (correct) diagnotic rate of hepatocholangiocarcinoma before operation was only 11.1%. The radical resection rate was 51.8%. Radical resection of the tumor had a better prognosis than that of non-resection of tumor.(Conclusions) Patients with long-term recurrent hepatolithiasis tended to have associated cholangiocarcinoma. Early diagnosis of the disease was difficult, and the treatment results and prognosis were poor. Therefore, (patients) with hepatolithiasis, espesially those with recurrent attacks, should undergo operation early. In cases diagnosed as hepatic cholangioearcinoma at operation, a radical resection should be performed, if possible, and a favorable outcome may be attained.
