- Abstract
Objective: To study the effects of allicin on cardiac function and underlying mechanism in rat model of myocardial infarction (MI)., Methods: Ninety-four Wistar rats were randomly assigned to 6 groups (n=14-16 per group): sham control group [underwent thoracotomy without left anterior descending (LAD) occlusion and only received an injection of the same amount of citrate buffer], MI control group (subjected to LAD occlusion and only received an injection of same amount of citrate buffer), positive control group (subjected to LAD occlusion and received an injection of diltiazem hydrochloride at the dose of 1.5 mg/kg), and MI + allicin groups (subjected to LAD occlusion and received an injection of allicin at the doses of 1.2, 1.8, and 3.6 mg/kg). All of the drugs were administered intraperitoneally daily for 21 days. The infarct area was measured by myocardial staining. Hematoxylin-eosin staining was used to observe the pathological changes. Cardiac function parameters were assessed by echocardiography. The myocardial apoptotic index was estimated by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining. The expression of Bax and Bcl-2 were detected by quantificational real-time polymerase chain reaction and Western blot., Results: Treatment with allicin could attenuate the myocardial infarct area (P<0.05) and relieve the changes of the myocardium. The left ventricular anterior wall diastolic and systolic thicknesses were increased in the allicin-treated groups (P<0.05), while there was no signifificant difference in the left ventricular posterior wall diastolic and systolic thickness (P>0.05). The left ventricular internal diameter in systole, ejection fraction, fractional shortening, and stroke volume were dramatically elevated in allicin-treated rats (P<0.05). Allicin dose-dependently reduced creatine kinase and lactate dehydrogenase levels (P<0.05). The myocardial apoptotic index was also markedly lowered, and Bax expression was signifificantly decreased, whereas Bcl-2 expression exhibited an opposite trend in allicin-treated rats (P<0.05)., Conclusion: Allicin appears to exert a cardioprotective effect that may be linked to blocking Bcl-2/Bax signaling pathway-denpendent apoptosis, further improving cardiac function.

- Abstract
Safety issues of traditional Chinese medicine injections has been heated debate. There are two diametrically opposed views: it should be used reasonable and developed healthily or be forbidden to use. Some people have many misunderstandings and prejudices about the safety of traditional Chinese medicine injections. Compared with western medicine,traditional Chinese medicine has its own particularity. Traditional Chinese medicine has complex components. Its research and clinical application is different from western medicine. Adverse reactions of traditional Chinese medicine injections are related to many factors,such as a large number of irrational use,blind use of traditional Chinese medicine injections and western medicine injections,counterfeit and substandard drugs,incorrect methods of intravenous infusion,toxicity of supplementary materials,drug ingredients. Developing traditional Chinese medicine injection is the need for curing sickness to save patients. The purposeful, targeted, organized and planned systematic research of traditional Chinese medicine injections should be strengthened,especially the safety of traditional Chinese medicine. Strengthen supervision and control of rational drug use.Strengthen the examination and approval,supervision and management of all aspects to ensure the safety of patients., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Chinese Pharmaceutical Association.)

- Abstract
Clinical re-evaluation is to verify the drug's safety and effectiveness again,while the drug itself has not been improved. However, due to the complexity of traditional Chinese medicine, ingredients in bulk drugs, prescription, productive processes, quality standards and other aspects need to be enhanced. So improving the quality, safety and effectiveness of traditional Chinese medicine by clinical re-evaluation is also very necessary. Therefore, except for achieving those basic requirements of medicine, it should also be improved on itself and pay full attention to the particularity, then traditional Chinese medicine's clinical re-evaluation will play its due role.

- Abstract
Beta-aescin, a natural triterpenoid saponin isolated from the seed of Chinese horse chestnut (Aesculus chinensis), is known to generate a wide variety of biochemical and pharmacological effects. In the present study, the authors investigated the anti-proliferative and apoptotic effects of beta-aescin in human chronic myeloid leukemia K562 cell line in vitro. The anti-proliferative effects were detected by CFU-K562 colony formation and cell viability assay. The apoptotic effects were analysed by morphological analysis, annexin V assay, DNA fragmentation assay and flow cytometry DNA content analysis. The results showed that beta-aescin exhibited potent dose- and time-dependent anti-proliferative effects in K562 cells. Morphological evidence of apoptosis, a significant increase of annexin V+ and PI- cells (early apoptotic) and apoptotic DNA fragmentation, were observed in cells treated with beta-aescin. Flow cytometry analysis revealed that beta-aescin could lead to an accumulation of sub G1 population in K562 cells, and suggesting a potential G1 phase accumulation in cell cycle profile of K562 cells. Our findings revealed that beta-aescin is a potent natural inhibitor of proliferation and inducer of apoptosis in K562 cells, and beta-aescin may be a candidate lead compound to explore potential antileukemia drugs.

- Abstract
In the present study, we compared cardioprotective effects of salvianolic acid B (Sal B) and the angiotension-converting enzyme inhibitor, benazepril, in rats with large myocardial infarction (MI). The large MI was produced by coronary artery ligation for 4 weeks in rats. The rats were divided into the following groups: sham operation; MI; MI + Sal B (100 mg/kg by a gavage, once a day for 4 weeks) and MI + benazepril (1 mg/kg by a gavage, once a day for 4 weeks). Echocardiogram, hemodynamic and hemorheological changes, angiogenesis, infarct size and cardiac remodeling, as well as messenger ribonucleic acid (mRNA) of vascular endothelium growth factor (VEGF) were measured. The following similar effects were observed in MI rats treated with Sal B and benazepril: (1) a marked improvement of echocardiographic, hemodynamic and hemorheological parameters, (2) significant reduction of infarct size, (3) significantly attenuated heart hypertrophy, left ventricular (LV) dilatation and fibrosis. The unique effects of Sal B were: angiogenesis and augmented VEGF expression in the border and remote noninfarcted LV area. These results suggest that Sal B and benazepril exerted beneficial cardioprotective effects. However, Sal B enforced some different modality than benazepril, which might improve myocardial microcirculation by augmenting VEGF expression and promoting angiogenesis besides similar effects to benazepril.

- Abstract
1. Fenofibrate and xuezhikang are two types of drugs widely used in the treatment of dyslipidaemia in China. The main purpose of present study was to test the efficacies and explore the potential mechanisms of action of the two lipid-lowering agents on high-fat diet-induced non-alcoholic fatty liver disease (NAFLD). 2. Rats were randomly divided into four groups, with eight rats per group. One group was given normal diet, whereas the other three groups were fed a high-fat diet. Forty-two days later, two of the high-fat diet-fed groups were administered fenofibrate (100 mg/kg, p.o.) and xuezhikang (300 mg/kg, p.o.) for another 42 consecutive days. The other two groups were administered placebo (saline) by gavage. 3. Typical pathological symptoms of NAFLD occurred in the high-fat diet groups. Fenofibrate and xuezhikang treatment markedly improved NAFLD, ameliorating dyslipidaemia and fat accumulation in the liver, improving insulin resistance and ameliorating oxidative stress. Hepatic steatosis, necro-inflammation and collagen deposition were lessened in the drug-treated groups. However, both xuezhikang and fenofibrate failed to reverse hepatomegaly and fenofibrate even aggravated it. Xuezhikang reversed aminotransferase abnormalities, but fenofibrate had less of an effect. 4. The common therapeutic mechanism of action of fenofibate and xuezhikang likely involves inhibition of the hepatic expression of tumour necrosis factor-alpha. Fenofibrate upregulated mRNA levels of peroxisome proliferator-activated receptor (PPAR) alpha in the liver, whereas xuezhikang had no effect on the hepatic expression of PPARalpha and this may explain, in part, their different effects on the NAFLD rats. 5. The results suggest that fenofibrate and xuezhikang may have potential clinical application in the treatment of NAFLD. However, the side-effects of fenofibrate and the underlying constituents of xuezhikang need to be determined and investigated further.

- Abstract
Objective: To investigate the effects of San Baoxin on myocardial injury induced by ischemia-reperfusion (MI/R) and thrombogenesis in rats in vivo and ex vivo., Method: The experimental model was established by ligation of left anterior descending coronary artery for 30 min followed by reperfusion for 180 min. The Chandler method was used to produced ex vivo thrombosis and an electrical stimulation of common carotid artery was adopted to form in vivo thrombosis respectively, the effect of antithrombosis induced by San Baoxin was observed., Result: San Baoxin significantly decreased the content of malondialdehyde (MDA), obviously elevated the activity of superoxide dismutase (SOD) and increased the amount of NO of the serum simultaneously. The San Baoxin at the dosage of 10 g x kg(-1) could remarkably lengthen the OT ( P < 0.05). All San Baoxin dosages could inhibit the formation of ex vivo thrombosis., Conclusion: San Baoxin protects the myocardium from injury of ischemic and reperfusion.

- Abstract
Perimenopause syndrome, referred also to climacteric syndrome, results from the changing of relationship among hypothalamus, pituitary and ovary during women's aging process. Those changes take place first in overy, then in hypothalmus and pituitary, which are reflected as the functional changes in endocrinological and central nervous system, accompanied with a series of psychological symptoms. 90% of women with perimenopause syndrome show clinical symptoms. The clinical prevention and treatment of female climacteric syndrome by traditional Chinese medicine: traditional Chinese medicine attributes the various symptoms of female climacteric syndrome to a variety of syndromes of Chinese medicine, e. g. gradual consumption of kidney-Qi, emptiness of the Ren and Chong channels, gradual exhaustion of Tienqui, breakdown of Yin-Yang equilibrium in the body, disorders of Zang-Fu, Qi and blood. The treatment based on syndrome differentiation, modification of prescription according to the symptoms, special prescription and simple recipe and acupuncture were employed in treating Yin-deficiency of the kidney, Yang-deficiency of the kidney, Yin and Yang-deficiency of the kidney, breakdown of the normal physiological coordination between the heart and the kidney, deficiency of liver-Yin and kidney-Yin, insufficiency of both the spleen and the kidney, deficiency of Qi and blood in the heart and spleen, stagnation of the liver-Qi and deficiency of the spleen, stagnation of the liver-Qi, phlegm stagnancy and the upward invasion of heat-phlegm. The traditional Chinese medicinal had a satisfactory global regulating effect on the nervous system and immune- regulating network with multifunction and unique advantage, e.g. its regulating effect on FSH, LH, E2, 5-HT, 5-HIAA, free radical and adtonomic nervous system. Experimental studies have also been conducted, e. g. There were also systematic studies of the simple Chinese drugs' pharmacodynamics and drugs forms of prepared drugs. In the health care of female climacteric syndrome the traditional Chinese medicine has also its own features and advantages.

- Abstract
Aim: To investigate the therapeutic effects of Guiyuanfang and bone marrow stem cells (BMSCs) on rats with liver fibrosis., Methods: Liver fibrosis model was induced by carbon tetrachloride, ethanol, high lipid and assessed biochemically and histologically. Liver function and hydroxyproline contents of liver tissue were determined. Serum hyaluronic acid (HA) level and procollagen III level were performed by radioimmunoassay. The VG staining was used to evaluate the collagen deposit in the liver. Immunohistochemical SABC methods were used to detect transplanted BMSCs and expression of urokinase plasminogen activator (uPA)., Results: Serum transaminase level and liver fibrosis in rats were markedly reduced by Guiyuanfang and BMSCs. HA level and procollagen III level were also reduced obviously, compared to model rats (HA: 47.18+/-10.97 ng/mL, 48.96+/-14.79 ng/mL; PCIII: 22.48+/-5.46 ng/mL, 26.90+/-3.35 ng/mL; P<0.05). Hydroxyproline contents of liver tissue in both BMSCs group and Guiyuanfang group were far lower than that of model group (1 227.2+/-43.1 microg/g liver tissue, 1390.8+/-156.3 microg/g liver tissue; P<0.01). After treatment fibrosis scores were also reduced. Both Guiyuanfang and BMSCs could increase the expression of uPA. The transplanted BMSCs could engraft, survive, and proliferate in the liver., Conclusion: Guiyuanfang protects against liver fibrosis. Transplanted BMSCs may engraft, survive, and proliferate in the fibrosis livers indefinitely. Guiyuanfang may synergize with BMSCs to improve recovery from liver fibrosis.
