Objective To evaluate the clinical efficacy of sodium tanshinone IIA sulfonate(STS)in the treatment of ad-vanced schistosomiasis. Methods Fifty cases with advanced schistosomiasis admitted to the Touzao Township Hospital of Dong-tai City during the period from November 2012 to November 2013 were treated with STS for 10 days,and the internal diameter of the portal vein,levels of ALT,AST,γ-GT,PIIIP,CIV,HA and LN were measured and compared before and after the adminis-tration of STS. Results The mean levels of all serological parameters except HA were within the normal range before STS treat-ment,while the highest positive rate was detected inγ-GT(26.0%)and HA(54.0%). Following the STS treatment,the mean lev-els of all parameters and the positive rates reduced,with the greatest reduction observed inγ-GT(36.7%)and HA(37.8%);how-ever,the mean HA level was still higher than the normal range. The mean internal diameter of the portal vein reduced from(10.5± 1.7)mm before the STS treatment to(9.8±1.3)mm after the STS administration,with a significant diffrtence(P<0.05). Conclu-sion STS appears effective in the treatment of advanced schistosomiasis.

ObjectiveTo investigate the clinical efficacy of warm needling moxibustion plus tricolor medicinal paste in treating knee osteoarthritis.MethodNinety-one patients meeting the diagnostic criteria were randomly allocated to a treatment group (45 cases) and a control group (46 cases). The treatment group was given warmneedling moxibustion plus tricolor medicinal paste and the control group, warm needling moxibustion alone. The clinical therapeutic effect and the WOMAC score were observed in thetwo groups. An improvement in the symptoms of knee osteoarthritis was assessed in the patients after treatment.ResultIn both groups, there were statistically significant pre-/post-treatment differences in the pain and daily activity scores and the WOMAC total score (P<0.05) but not in the morning stiffness score (P>0.05). There were statistically significant differences in the daily activity score and the WOMAC total score (P<0.05) but not in the pain and morning stiffness scores (P>0.05) between the two groups.Conclusion The study shows that warm needling moxibustion plus external application of tricolor medicinal paste has a marked improving effect on the pain, swelling and physiological functions in patients with knee osteoarthritis. Improving lower limb function further in daily activities can produce a satisfactory and stable therapeutic effect.

OBJECTIVE To discuss the preventive methods of hepatitis B virus reinfection after liver transplantation. METHODS Eighty eight liver transplantation recipients with HBV-related end-stage liver diseases including chronic fulminant hepatitis B,end-stage liver cirrhosis and liver carcinoma were analyzed retrospectively,and were given lamivudine pre-transplantation to prevent hepatitis B virus reinfection.Post-transplantation medicines of lamivudine were administered in 3 cases;lamivudine and hepatitis B immunoglobulin(HBIg) in 85 cases.The follow-up criteria included serum HBV,HBV-DNA,liver biopsy,immunohistochemical study of liver biopsy specimens and clinical manifestations.All of patients were followed-up 6 months at least.RESULTS Two of the three cases who taken lamivudine developed reinfection,the little time is 6 months following liver transplantation.There were three of eighty five cases taken lamicudine and HBIg(small dosage) developed reinfection.CONCLUSIONS Liver transplantation is an effective treatment for HBV-related end-stage liver diseases.Given lamivudine at the pre-transplantation could reduce the levels of the HBV virus copies.Lamivudine and HBIg post-transplantation offer effective prevention against hepatitis B virus reinfection.

Objective To detect the levels of CD31+/CD42b- and CD144+ endothelial microparticles (EMPs)in plasma,and analyze the relationship with carotid intima-media thickness (CIMT)and the risk factors of atherosclerosis.Methods Totally 122 outpatients and inpatients in our hospital were selected,and carotid artery ultrasound examination was performed.The results were divided into a thickening group (62 cases)and a control group (60 cases).Flow cytometry was used to detect the levels of CD31+/CD42b- and CD144+ EMPs in the blood to analyze the relationship between the level of endothelial cells and CIMT,and to investigate the relationship between the level of plasma EMPs and the risk factors of atherosclerosis.Results Compared with the control group,the levels of EMPs of CD31+/CD42b- and CD144+ were significantly higher.In the correlation analysis, plasma CD31+/CD42b- and CD144+EMPs levels were positively correlated with CIMT;in multi-factor Logistic regression analysis,CD31+/CD42b- EMPs levels were correlated positively with age,TC and Cys C;plasma CD144+ EMPs levels were correlated with UA and BMI.Conclusion The levels of CD31+/CD42b-,CD144+EMPs in plasma were correlated with CIMT,guiding early prevention of cardiovascular diseases.

Objective To investigate the clinical significance of soluble CD40 ligand (sCD40L ) and lipoprotein associated phospholipase A2 (Lp-PLA2 ) in the assessment of coronary artery severity and risk classification in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS).Methods Of the 9 6 patients with coronary heart disease diagnosed by coronary angiography,2 8 patients had stable angina pectoris (SAP),38 patients unstable angina pectoris (UAP)and 30 patients acute non-ST-segment elevation myocardial infarction (NSTEMI).Another 30 patients with non-coronary heart disease (NC)served as controls.The sCD40L and Lp-PLA2 levels were determined by enzyme-linked immune sorbent assay (ELISA)method.The Gensini score was used to assess the severity of coronary artery and analyze the correlation with sCD40L and Lp-PLA2.The correlation of sCD40L and Lp-PLA2 with GRACE risk score was analyzed too.Results ① sCD40L was significantly higher in NSTEMI and UAP groups than in SAP and NC groups (P<0 .0 5 ),but there was no significant difference between NSTEMI and UAP groups (P>0 .0 5 )or SAP and NC groups (P>0 .0 5 ).Lp-PLA2 was significantly higher in NSTEMI group than in UAP,SAP and NC groups (P<0.05).Lp-PLA2 was significantly higher in UAP group than in SAP and NC groups (P<0.05).② We found that sCD40L had obvious correlation with Lp-PLA2 (r=0.284, P<0.01),Gensini score (r=0.213,P<0.05),and GRACE (r=0.224,P<0.05).Lp-PLA2 was significantly correlated with Gensini score (r=0.270,P<0.05),and GRACE (r=0.323,P<0.01).③ Multivariate logistic regression analysis showed that Lp-PLA2 was independently associated with NSTE-ACS (P<0.05).Conclusion The sCD40L and Lp-PLA2 which were significantly elevated in NSTE-ACS are correlated with the severity of coronary artery disease.The two indexes indicate the instability of atherosclerotic plaque;thus they can be used as predictors of risk assessment in coronary heart disease.
