Objective To study the efect of IH764-3 on ischemia-reperfusion (I/R) injury in rat liver. Methods Rats were divided into 3 groups, the control group was not subjected to ischemia and no treatment was given. I/R injury group was subjected to 40 minutes ischemia followed by reperfusion for 120 minutes. The IH7643 group (40mg/kg) was administred at ischemia and reperfusion. Results In the IH764-3 group, sereum levels of ALT, AST, AKP and γ-GT were significantly lower than those in the I/R group. Energy charge level recovery was significantly higher with IH7643 (P＜0.05), hepatic ultrastructure was better preserved with IH764-3. Conclusion IH764-3 may be useful in the treatment of hepatic ischemia reperfusion injury
ObjectiveTo observe the protective effect of tanshinone Ⅱ A on the mouse liver ischemia-reperfusion injury (IRI) model and preliminarily explore its mechanism of alleviating liver injury.MethodsThe IRI mouse model was established after the pre-treating with tanshinone Ⅱ A. Then, the serum and liver tissue of mice were collected to detect the changes of liver function, histopathology, liver cell apoptosis, and inflammatory factors. In addition, the protein expression levels of high mobility group box 1 (HMGB1), advanced glycosylation end-product specific receptor (RAGE), and Toll like receptor 4 (TLR4) in the liver tissues were detected by the Western blot method.ResultsAll data were analyzed by the homogeneity of variance test. The results of factorial design showed that the levels of ALT and AST in the serum, the pathological score and apoptosis index, the inflammatory response, as well as the expressions of HMGB1, TLR4 and RAGE proteins in the liver tissues were decreased significantly (P<0.05) in the sham operatation plus tanshinone Ⅱ A mice, which were increased significantly (P<0.05) in the IRI mice, which were antagonized synergistically by the tanshinone ⅡA and IRI (P<0.05).ConclusionsTanshinone ⅡA could reduce the liver IRI and inflammatory response in mouse. These effects might be related to the down-regulations of TLR4, HMGB1, and RAGE expressions.
Objective To investigate the physicochemicalproperties of the calcium phosphate cement (CPC) containing Danshen composite injection and its drug release rate. Methods This experiment included 4 groups and each group contained 6 specimens. CPC (2 g) was mixed with the setting solution that served as thecontrol group; 0.1,0.5 and 1.0 ml of Danshen composites injection (concentration, 1 000 mg/ml; pH, 7.35) were respectively added to CPC (2 g), which were used as the experimental groups 1, 2 and 3. The resulting specimens were investigated by the X-ray diffraction (XRD), the fourier transformed infrared spectroscopy(FTIR), and the scanning electron microscope (SEM).ResultsThe XRD analysis showed that the control group had a typical diffraction pattern of the hydroxypatite (HAP), which was consistent with the standard patternof HAP. When more Danshen was added in the experimental groups, the diffractionpeaks of HAP gradually decreased; when the diffraction angle 2θ was about 25.92°, the HAP peaks disappeared. Based on the FTIR analysis, with an increase of the drug concentration, the absorption peak of the hydroxy groups decreased. The SEM showed that the size of the CPC particle was related to the drug concentration; with an increase of the drug concentration, the CPC particle increased in number, resulting in an increasing trend of coacervation. The elution test showed that the drugrelease rate and capacity varied with the different concentrationsof Danshen. The initial release rate was relatively great, but after 96 hours the rate slowed down, lasting for a long time. Conclusion The physicochemical properties of CPC do not change when a proper dose (0.1 ml/2 g) of Danshen isadded to CPC. The Danshen composite can be effectively released from CPC, and so CPCcan be used as an ideal drugdelivery carrier for Danshen composite.
Objective To investigate the current situation of randomized controlled trials (RCTs) on compound salvia pellet (CSP) for angina pectoris and assess whether there is adequate evidence for clinical practice. Methods We collected all the published clinical studies on CSP for angina pectoris from 1994 to December 2005, and assessed each included report using the Jadad scale, the revised CONSORT statement and other self-edited items. Results We finally identified 115 RCTs. Among which, 1 scored 3 points, 6 scored 2 points, 106 scored 1 points and 2 socred 0 points. No RCT performed allocation concealment according to the CONSORT criteria, only 4 RCTs (3.5%) described the generation of the randomization sequence, among which 2 were quasi-randomized. No RCT provided randomization implementation,1 RCT (0.9%) carried out placebo control, 1 RCT (0.9%) reported endpoint, 9 RCTs (7.8%) adopted single blinding, 4 RCTs (3.5%) reported double blinding, 11 RCTs (9.6%) calculated statistical values, 2 RCTs (1.7%) provided the record of follow-up, 1 RCT (0.9%) reported negative outcome, 25 RCTs (21.8%) described adverse events, no RCT described how the sample size was estimated, and how an intent-to-treat (ITT) analysis and correlation analysis were reported, 1 RCT (0.9%) was multi-center, no RCT completed ethical approval and informed consent, 27 RCTs (23.5%) described syndrome type of TCM. Conclusion Currently, the methodology and reporting of studies on CSP for angina pectoris are not good enough to provide reliable evidence for clinical practice.

ObjectiveTo systematically review the effectiveness and safety of salvianolate injection and Danshen injection for patients with angina pectoris, and evaluate the cost of drug. MethodsWe electronically searched databases including PubMed, CENTRAL (Issue 4, 2013), CNKI, VIP and WanFang Data (2004.1 to 2013.5) for the randomized controlled trials (RCTs) on the comparison between salvianolate injection and Danshen injection for angina pectoris from January 2004 to May 2013. Relevant journals and conference proceedings were also manually retrieved. Two reviewers independently screened literature in accordance with the inclusion and exclusion criteria, extracted the data and assess the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software. ResultsA total of 10 RCTs involving 1 196 patients were included. The results of meta-analysis showed that, salvianolate injection was obviously superior to Danshen injection in the effectiveness (OR=3.79, 95%CI 2.78 to 5.17, P < 0.000 01) and safety (OR=0.24, 95%CI 0.09 to 0.64, P=0.004), but lack of economic advantages in the treatment of the angina pectoris diseases. ConclusionCurrent evidence indicates that, salvianolate injection is a safe and effective scheme for angina pectoris, and Danshen injection is considered as a economic method. Because of the limited quantity and quality of currently-available research, the aforementioned conclusion should be verified by strictly-designed and large-scale sample RCTs.
