Developing traditional Chinese medicine injection is the need for curing sickness to save patients / 中国中药杂志

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.

Allicin improves cardiac function by protecting against apoptosis in rat model of myocardial infarction / 中国结合医学杂志

<p><b>OBJECTIVE</b>To study the effects of allicin on cardiac function and underlying mechanism in rat model of myocardial infarction (MI).</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSION</b>Allicin appears to exert a cardioprotective effect that may be linked to blocking Bcl-2/Bax signaling pathway-denpendent apoptosis, further improving cardiac function.</p>

Relationship between law on the protection of wildlife and animal-derived drugs / 中国中药杂志

In most countries, the protection of wildlife resources is in a negative way, the state do not put emphasis on or even oppose artificial breeding, with the poor results. In our country, the state shall pursue a policy of strengthening the protection of wildlife resources, actively domesticating and breeding the species of wildlife, which has made great achievements. Traditional Chinese medicine(TCM) is one pillar of medical and health service in China, animal-derived drugs which are effective drugs for the treatment of certain critical cases have been used in clinic for 2 000 years. Prohibition or limited use of animal-derived drugs could affect the curative effect, hindering TCM from healthy development. The state shall encourage the protection and domestication, breeding of wildlife accords with our national conditions, which is not only beneficial to the protection of wildlife, but also favors the development of the cause of TCM.

Specificity of traditional Chinese medicine's clinical re-evaluation / 中国中药杂志

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.

Progress on the research of prevention and treatment of female climacteric syndrome by traditional Chinese medicine / 中国中药杂志

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.
