Objective: To observe effect of salvia miltiorrhiza and ligustrazine injection on patients with acute episode of chronic pulmonary heart disease (CPHD) complicated pulmonary artery hypertension. Methods: A total of 40 CPHD patients with pulmonary artery hypertension were randomly divided into routine treatment group (n=20, received routine treatment) and observation group (n=20, received salvia miltiorrhiza and ligustrazine based on routine treatment). Another 20 healthy subjects were regard as healthy control group. The pulmonary artery pressure (PAP), partial pressure of oxygen in artery (PaO2) , left ventricular ejection fraction (LVEF) and levels of C-reactive protein (CRP) and endothelin-1 (ET-1) were examined and analyzed in all groups before and after treatment. Results: After treatment, compared with routine treatment group, there were significant increase in total effective rate (75% vs. 90%) and PaO2 [（83.87±14.53）mmHg vs.（92.95±13.54）mmHg], and significant decrease in mean PAP [mPAP, （55.43±9.65）mmHg vs.（45.52±8.89）mmHg], CRP [(6.37±2.12) mg/L vs. (3.29±0.84) mg/L] and ET-1 [(52.37±20.79) ng/L vs. (40.29±16.04) ng/L] in observation group (P<0.05~0.01). There was no significant difference in LVEF between the two groups after treatment (P>0.05). Conclusion: For patients with acute episode of chronic pulmonary heart disease complicated pulmonary artery hypertension salvia miltiorrhiza and ligustrazine injection can significantly improve clinical effects，right heart function, decrease mean pulmonary artery pressure, improve endothelial function and inhibit inflammatory reactions.

Objective To explore the effects of kurorinone on the serum level of TNF-? and IL-6 in the patients with chronic hepatitis B (CHB). Methods 87 patients with CHB were randomly divided into groups A and B. Patients in group A (n=45) and group B (n=42) received kurorinone and diammonium glycyrrhizin treatment, respectively, for 3 months. The liver histopathological changes were observed, and liver function and the serum level of TNF-? and IL-6 in the patients with CHB were detected after treatment. Results Compared with group B, liver injury and liver function of the patients in group A were obviously ameliorated, and the serum level of TNF-? and IL-6 significantly decreased (P

Objective To evaluate the effects of kurorinone combined with thymosin on the treatment of chronic hepatitis B. Methods 178 patients with chronic hepatitis B were randomly divided into group A, B and C. 64 patients in group A received kurorinone combined with thymosin for 3 months. 58 patients in group B received kurorinone only, and 56 patients in group C received thymosin only. Results At the end of treatment, HBeAg and HBV DNA negative-transformed rates were respectively 51.8% and 53.6% in group A, but 32.7% and 34.6% in group B, 21.6% and 21.6% in group C, the differences were statistically significant (P

Objective To explore the role of tumor necrosis factor (TNF-?) and endotoxin(LPS) in upper gastrointestinal bleeding in cirrhosis patients and the preventive and treatment mechanism of rhubarb. Methods 45 liver cirrhosis patients with upper gastrointestinal bleeding were treated with rhubarb, and its efficacy was compared with cemetidine's efficacy. Liver function, and serum levels of TNF-? and LPS were measured before and after the therapy. Results Patients’symptoms and liver function were improved, and serum levels of TNF-? and LPS significantly decreased after treated with rhubarb. Conclusions TNF-? and endotoxin might play an important role in upper gastrointestinal bleeding in cirrhosis patients. Rhubarb has protective and treatment effect on upper gastrointestinal bleeding in cirrhosis patients by reducing TNF-? and LPS release.

Objective To explore clinical characteristics and surgical treatment of pancreatic duct stone.Methods Clinical data of 25 cases pancreatic duct stone undergoing operation from 1990 to 2008 were retrospectively analyzed. Results All of the 25 cases suffered upper abdominal pain, among whom 8 cases were concomitant with type 2 diabetes mellitus, 5 with steatorrhea, 2 with obstructive jaundice, 1 with pancreatic head cancer and 6 with acute pancreatitis recurrence history. All cases were confirmed by imaging diagnosis, such as ultrasonography, abdominal X-ray film, CT, endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography. 20 cases underwent pancreolithotomy with Roux-en-Y side-to-side pancreaticojejunostomy. 4 cases underwent body-tail pancreatectomy with pancreatojejunostomy and 1 case underwent pancreatoduodenectomy. No complication was found. 25 cases were followed for 2 months to 4 years after operation. Among all 25 cases with upper abdominal pain, 20 cases got rid of the symptoms and 5 cases were relieved postoperatively.Among 8 cases with diabetes mellitus, 4 cases resumed normal blood glucose postoperatively. Among 5 cases with steatorrhea, steatorrhea disappeared in 2 cases and 1 case were alleviated postoperatively. Conclusions Imaging examinations are the main diagnostic methods for pancreatic duct stone. Pancreolithotomy and Roux-en-Y side-toside pancreaticojejunostomy are effective operative techniques.

Objective To study the efficacy of interferon ? 2b (IFN? 2b) combined with kurorinone in the treatment of chronic hepatitis B. Methods 146 patients with chronic hepatitis B were randomly divided into four groups(A,B,C,D). Based on the similar general treatment(group D),37 patients in group A was treated with IFN ? 2b and kurorinone. However, 37 patients in group B and 36 patients in group C received IFN ? 2b and kurorinone,respectively.Dynamic changes and relationships among liver histopathology,expression of TGF ? in liver tissue and serum levels of TGF ?,HBeAg,HBV DNA were studied using immunohistochemistry,radioimmunoassay and ELISA before and after treatment of IFN ? 2b and kurorinone. Results The score of histological hepatitic fibrosis,expression of TGF ? in liver tissue and serum levels of TGF ?,HBeAg, HBV DNA in group A showed significant lower than in group B and group C ( P

Objective To investigate the positive rate of microembolic signal (MES) and the related factors,as well as the correlation between MES and outcomes in patients with cardiogenic cerebral embolism.Methods Patients with cardiogenic cerebral embolism were enrolled.The baseline data of the patients were collected and the MES monitor was conducted.The baseline data of the MES positive group and MES negative group were compared.Multivariatelogistic regression analysis was used to identify the related factors of the positive MES.The patients were followed up regularly.The outcomes of stroke at 6 months and recurrent stroke within 2 years in the MES positive group and MES negative group were compared.Results A total of 165 patients with cardiogenic cerebral embolism were enrolled,including positive MES in 68 patients (41.2％).There were significant difference in the levels of brain natriuretic peptide (BNP),cardiac troponin-I (cTn-I),and D-dimer between the MES positive group and negative group.Multivariate logistic regression analysis showed that the increased levels of baseline BNP (odds ratio [OR] 1.001,95％ confidence interval CI 1.001-1.002;P＜0.001),cTn-I (OR 36.975,95％ CI 1.516-902.0;P=0.027),and D-dimer (OR 1.001,95％ CI 1.000-1.001;P=0.017) were independently associated with the positive MES in cerebral embolism within 48 h after onset.There was no significant difference in the proportion of patients in good outcome (modified Rankin scale score 0-2) and poor outcome (modified Rankin scale score ＞2) after 6 months between the MES positive group and MES negative group.When the average follow-up time was 20.8 months (range,7-24 months),there were 23 patients (33.8％) and 19 (19.6％) had recurrence in the MES positive group and MES negative group,respectively.Kaplan-Meier analysis showed that the recurrence rate of stroke in the MES positive group was significantly higher than that in the MES negative group (log-rank test:P=0.031).COX regression analysis showed that the positive MES was still an independent risk factor for stroke recurrence after adjusting for other confounding factors (OR 0.328,95％ CI 0.142-0.761;P=0.009).Conclusions The positive MES was associated with the increased BNP,cTn-I,and D-dimer levds.The positive MES was not associated with clinical outcomes at 6 month after the onset,but it was associated with the recurrence of stroke within 2 years.
