OBJECTIVETo study the HIV incidence and risk factors among sero-negative spouses of HIV patients in Dehong prefecture of Yunnan province.
METHODSA cohort of sero-negative spouses of the HIV patients had been developed and followed up since November, 2005. HIV new infections and related behaviors had been investigated every six months.
RESULTSBy the end of June, 2008, 790 sero-negative spouses of HIV patients had been recruited, of whom 702 were followed-up for at least one time. During the total 1202.35 person-years, 31 new HIV infections were identified, with an overall incidence of 2.58/100 person-years. The HIV incidence rates were 2.22/100 person-years in 2006, 2.95/100 person-years in 2007 and 2.74/100 person-years in 2008. Data from the Cox proportional hazard regression model indicated that those who resided in Yingjiang county [hazard ratio (HR) = 4.37, 95%CI: 1.48 - 12.90, P = 0.008], ever using drugs (HR = 3.49, 95%CI: 1.09 - 11.18, P = 0.035), or having an HIV-infected spouse who never exposed to antiretroviral treatment (HR = 3.60, 95%CI: 1.41 - 9.16, P = 0.007) were at higher risk for HIV infection.
CONCLUSIONSero-negative spouses of HIV patients in Dehong prefecture of Yunnan province had a relatively high incidence of HIV new infection during 2006-2008. More efforts should put on those people living in these areas, having a history of drug use or having an HIV-infected spouse who had never been exposed to antiretroviral treatment.

This paper aims to discuss the potential targets,pathways and possible mechanisms of Danhong Injection in treatment of aspirin resistance by using network pharmacology concept and network analysis technique. Active ingredients and potential targets of Danhong Injection were collected from TCMSP database and the ingredients were further screened based on their topological characteristics. The active ingredients with nodal degree of freedom≥9 were selected as the main active ingredients. Targets related to aspirin resistance were collected from Genecards database. Drug-active ingredient-target-disease network was constructed by using Cytoscape3. 7. 0,and Funrich 3. 1. 3 software was used for gene enrichment analysis. Sixty main active ingredients were screened out from 110 active ingredients of Danhong Injection,including 51 ingredients in Salviae Miltiorrhizae Radix et Rhizoma and 11 ingredients in Carthami Flos,2 of which were both in Salviae Miltiorrhizae Radix et Rhizoma and Carthami Flos. In addition,159 potential targets were collected. The results of gene enrichment analysis showed that Danhong Injection could improve aspirin resistance mainly through21 pathways involving coagulation process,inflammatory response and metabolism. This study revealed the effects of Danhong Injection for improving aspirin resistance in multi-component,multi-target and multi-pathway means mainly through regulation in coagulation process,inflammatory response and metabolism,providing more abundant information and basis for subsequent research and experimental work.

BACKGROUNDCoronary artery disease (CAD) is generally considered as a disease of middle-aged men. It is widely accepted that the risk for CAD of premenopausal women is low because of hormone protection. Based on our clinical experience, more and more premenopausal women suffer from angina and myocardial infarction without adequate concern. Even now, there are still limited detailed data to describe the characteristics, mechanism and prognosis of premenopausal CAD patients. This article aimed to analyze the clinical and angiographic characteristics of premenopausal women with CAD.
METHODSA total of 565 premenopausal women and 721 postmenopausal women (56 - 60 years old) who underwent coronary angiography for the first time from April 2004 to December 2007 were enrolled. The clinical data and coronary angiographic characteristics (presence, localization, length and severity) were compared between the premenopausal and postmenopausal CAD groups.
RESULTSPremenopausal CAD patients presented less frequently with hypertension, diabetes mellitus and dyslipidemia compared with postmenopausal CAD patients (55.0% vs 66.0%, 15.0% vs 31.5%, 23.9% vs 37.4%, respectively; all P < 0.05). Although we found more frequent involvement of single vessel in premenopausal CAD (43.2% vs 26.9%, P = 0), and triple vessels in postmenopausal (56 - 60 years old) CAD patients (33.8% vs 20.4%, P = 0), much more severe lesions (> or = 90%) at left main (2.9% vs 1.1%, P = 0.048) and proximal left anterior descending artery (LAD) (28.2% vs 16.6%, P = 0) in the premenopausal CAD group were found.
CONCLUSIONPremenopausal women with chest discomfort are always found to have obvious atherosclerosis, more inclined to be located at the left main and proximal LAD, which is a strong predictor of an adverse clinical outcome.

Dendrobii Caulis are commonly used tonic Chinese medicinal materials with a long history of application. As demonstrated by pharmacological results, the chemical constituents and the extracts of Dendrobii Caulis have anti-inflammatory, antibacte-rial, antioxidant, and anti-tumor effects, and can also regulate immunity, lower blood pressure, and regulate blood sugar. The active ingredients contained are widely concerned by scholars. This paper comprehensively summarized the chemical constituents and pharmacological activities of Dendrobium plants reported so far. The chemical constituents isolated from Dendrobium plants are mainly alkaloids, sesquiterpenoids, flavonoids, fluorenones, coumarins, bibenzyls, phenanthrenes, lignans, steroids, phenols, and polysaccharides. This paper is expected to provide a reference for further research, development, and utilization of Dendrobium plants.

Through consulting the ancient herbal and medical books, combined with the field investigation, the name, origin, collection and processing of Dendrobium medicinal materials were researched, which provided a basis for the development of famous classical formulas containing this kind of herbs. Due to the wide distribution of D. officinale, the Dendrobium species represented by D. officinale and D. huoshanense, which are short, fleshy and rich in mucus, should be the most mainstream of Dendrobium medicinal materials in previous dynasties. Compared with Shihu, Muhu with loose texture, long and hollow is born on trees. According to the characteristic description, it should be D. nobile, D. fimbriatum and so on, of which D. nobile was the mainstream. The Chinese meaning of Jinchai was confused in the past dynasties, so it was not suitable to be treated as a plant name. The production areas of Dendrobium medicinal materials in the past dynasties have changed with the discovery of varieties, artificial cultivation and other factors. Lu'an, Anhui province, was the earliest recorded in the Han and Wei dynasties. Since the Tang and Song dynasties, it had been extended to Guangdong and Guangxi, and it was considered that "Dendrobii Caulis in Guangnan was the best". In the Ming dynasty, Sichuan and Zhejiang products were highly praised, and in the Qing dynasty, Huoshan products were highly praised. Dendrobium medicinal materials had been used as medicine by stems in all dynasties. The medicinal materials were divided into fresh products and dry products. The fresh products can be used immediately after removing the sediment from the roots. The dry products need further processing, most of them used wine as auxiliary materials for steaming, simmer to paste or decoction into medicine. D. officinale and D. huoshanense have special processing specifications since the middle of Qing dynasty, that is, "Fengdou". According to the research results, in Ganluyin, the effect of Dendrobium medicinal materials is mainly heat clearing, and D. nobile with bitter taste can be selected. The main effect of Dendrobium medicinal materials in Dihuang Yinzi is tonic, D. officinale or D. huoshanense can be selected.
