Objective:To explore the mental health status of the first-degree relatives of the heroin addicts. Methods: Three hundred twenty first-degree relatives of the heroin addicts were evaluated with SCL-90. Results: The scores of somatization, depression, anxiety, paranoia, and psychiatric factor among the first-degree relatives were significantly higher than the national norm. The first-degree relatives of heroin addicts who had addicted more than 5 years had significantly higher score than the relatives of heroin addicts who had addicts less than 5 years. Conclusion: The mental health condition of the first-degree relatives of heroin addicts was poor, especially those relatives of heroin addicts who have addicted for more than 5 years.

Objective:To investigate the long-term toxicity of recombinant human interleukin-11(rhIL-11) in cynomolgus. Methods: Eighteen cynomolgus were randomized into 4 groups: control group(2/sex), low dose group(2/sex), medium dose group(2/sex)， and high dose group(3/sex). The drug groups were sc adminstered 0.1, 0.3 and 1.0 mg/kg of rhIL-11 for 90 days with a 30-day recovery period. The clinical signs were observed, electrocardiogram, hematological, biochemical, urinary and immunological parameters were measured, organ masses were weighed, bone marrow and pathological histology were observed. Results: The food consumption, body mass of the drug groups were decreased, the body temperature was increased transiently. One of the low dose group showed restricted movements and tremors. One of the high dose group vomited and another died. Reduced red blood cell(RBC) count, hemoglobin(Hb) concentration, hematocrit(Hct), mean corpuscular volume(MCV), mean corpuscular hemoglobin(MCH), and mean corpuscular hemoglobin concentration(MCHC), dose-related increase of platelet(Plat) counts were present in drug groups. Biochemical examinations revealed dose-related decreases in serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), lactate dehydrogenase(LDH), total proteins(TP) and albumin(Alb) increases in serum alkaline phosphatase(ALP) levels. Positive antibody responses were seen and circulatory immune complex(CIC) was significantly increased in all drug groups. Hypertropy of marrow megakaryocyocytes was noted in the medium and high dose groups. The heart and liver masses were slightly increased in all treatment groups. Treatment-related microscopic findings included dose-related degeneration in the liver and the kidney. The adverse effects were reversed by the end of the recovery period. Conclusion: The target organs and systems are blood, liver, kidney, immmue system and bone marrow. The toxicity injuries were reversible and the no-toxic-effect level is 0.1 mg/kg.

Shiwei Dangguiyin(SWDGY)is mainly composed of Radix Angelicae Sinensis,Radix Adenophorae,Radix Notogenseng,Radix Bupleuri,etc. Oral administration of SWDGY could significantly inhibit the metatarsal swell- ing eaused by dimethylbenzene in rats,raise the pain threshold in hot-plate test and depress the torsive reaction caused by acetic acid in mice.In vitro SWDGY exerted bacteriostatic and bacteriocidal effects on Staphylococcus aureus,Bacil- lus pyocyaneus,Escherichia coli,Streptococcus A,B and C.It was shown that SWDGY possessed anti-inflammatory,analgesic and antiseptic effects in vitro.In mice LD_(50) of SWDGY by oral administration was more than 840g/kg.Affer cral adminstration in a daily dose of 189.Sg/kg continuously for one month in rats, no toxic reactions appeared,This dosage was 118.6 times as much as the clinical one.

Background Traditional Chinese medicine (TCM), especially herbal medicine, has been widely used in China and now is also being increasingly used in other countries for the treatment of cardiovascular diseases. Although many studies have demonstrated that certain Chinese herbal products are effective and safe for the treatment of cardiovascular diseases, most of these lack sufficient quality. Therefore, large randomized clinical trials and further scientific research to determine its safety, effectiveness are necessary.QiShen YiQi Dripping Pills (QSYQDP) is a herbal preparation clinically used in the treatment and prevention of coronary artery disease. Preliminary observations have shown its safety and effectiveness. Methods/Design This randomized, controlled trial will recruit 3600 patients with a history of myocardial infarction. Patients will be randomized into two groups by a Centr-Randomized System. One group receives QSYQDP, the other group receive aspirin. This trial protocol will describe eligibility criteria, detailed information on the treatment definition, blinding, endpoints, statistical methods, sample size determination, data management, legal aspects, and the current status of the trial. Discussion This trial is one of the first randomized, controlled clinical trial to evaluate the efficacy and safety of traditional Chinese herbal medicine in the treatment and secondary prevention of coronary artery disease. The results of this study should help to define the role of TCM in modern medical care, as well as to provide the management strategy for CAD patients in China and other countries.

Stroke is a neurological disease characterized by cerebral ischemia or hemorrhagic injury， leading to death and disability worldwide. At present， there is still a lack of neuroprotective drugs for the treatment of stroke. Niuhuang Qingxin pills are Chinese patent medicine recommended by guidelines and expert consensus for preventing and treating stroke. Studies have shown that Niuhuang Qingxin pills have sedative， anticonvulsant， antipyretic， and other pharmacological effects. Moreover， the main components， such as flavonoids， phenolic acids， and saponins， also exhibit strong pharmacological activities which can improve stroke-induced nerve damage. Studies have confirmed that representative ingredients such as baicalin and ginsenosides can interfere with multiple pathological events， including blood-brain barrier destruction， oxidative stress， inflammatory response， apoptosis， and autophagy， and the mechanisms of the essential ingredients are related to the action on important targets such as Kelch-like ECH-associated protein 1 （Keap1）， matrix metalloproteinase-9 （MMP-9）， and high-mobility group box 1 （HMGB1）， and involvement in the regulation of Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB）， nuclear factor E₂-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1）， and phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathways. This article summarized the research status of Niuhuang Qingxin pills and the experimental pharmacological progress of common ingredients in the prevention and treatment of stroke to provide clues for further research into Niuhuang Qingxin pills and the development of active ingredients of traditional Chinese medicines.
