To evaluate the mental health of occupational females in different industries. We investigated the psychologic status of Chinese occupational females using symptom checklist 90. And statistical software was applied to analyze results of symptom checklist 90.

Knowledge, attitude, and status of nitrite inhalant use among men who have sex with men in Tianjin, China.

Background: Nitrite inhalants have become popular as recreational drugs among the homosexual population in some developed countries since the 1980s. These drugs, also called RUSH in China, have become attractive among Chinese men who have sex with men (MSM) in the past few years. The aim of this cross-sectional study was to understand the knowledge, attitude, and status of nitrite inhalant use among Chinese MSM.

[The application of lipoprint-system for analysis of sub-fractional spectrum of lipoproteins of blood serum.].

The lipoproteins of low and high density are presented by heterogeneous specter of particles differing by size, density, charge, composition and functional characteristics. The prevalence of small dense particles of lipoproteins of low and high density in blood plasma is associated with higher risk of development of coronary heart disease. The identification of subfractional spectrum of lipoproteins in clinical purposes is complicated because of requirement of expensive equipment and reagents and extended time of implementation.

Latent tuberculosis infection and occupational protection among health care workers in two types of public hospitals in China.

Objective: To determine the impact factors of latent tuberculosis infection (LTBI) and the knowledge of TB prevention and treatment policy among health care workers (HCWs) in different types of hospitals and explore the strategies for improving TB prevention and control in medical institutions in China.

Methods: A cross-sectional study was carried out to evaluate the risk of TB infection and personnel occupational protection among HCWs who directly engage in medical duties in one of two public hospitals. Each potential participant completed a structured questionnaire and performed a tuberculin skin test (TST).

Effects of endogenous regulators of endothelial NO synthase on nitric oxide homeostasis and blood serum lipoproteins during experimental diabetes mellitus.

Experimental diabetes mellitus was associated with the development of oxidative stress and a decrease in blood concentration of total nitric oxide (NO) metabolites. Administration of L-arginine induced positive changes in the LPO-antioxidant enzyme system and elevated NO concentration in blood serum, whereas L-NAME, inhibitor of eNOS (NOS-III) increased LPO intensity via SOD inhibition and reduced NO content. Combined administration of Q10 and L-arginine led the suppression of oxidative stress and significant increase in NO level.

Simvastatin and preparation of polyunsaturated phospholipids produce similar changes in the phospholipid composition of high-density lipoproteins during hypercholesterolemia.

We studied the phospholipid composition of high-density lipoproteins in patients with coronary heart disease and hypercholesterolemia treated with simvastatin (Zocor, inhibitor of the key enzyme of cholesterol synthesis) and preparation of polyunsaturated phospholipids (lipostabil forte). Simvastatin produced a hypolipidemic effect and modulates the phospholipid composition of high-density lipoproteins (similarly to lipostabil forte). These changes contribute to functional activity of high-density lipoproteins in the reverse cholesterol transport.

Effects of simvastatin on the phospholipid composition of high-density lipoproteins in patients with hypercholesterolemia.

We studied the phospholipid composition of high-density lipoproteins in patients with hypercholesterolemia before and after treatment with simvastatin. Individual phospholipids were separated by thin-layer chromatography on glass plates coated with silica gel. It was found that apart from hypolipidemic effect, simvastatin changed the concentration and phospholipid composition of high-density lipoproteins, which improved their cholesterol-accepting and cholesterol-transporting properties.

Phospholipid composition of high-density lipoproteins reflects lipolysis of triglyceride-rich lipoproteins during hyperlipidemia.

We studied phospholipid composition of high-density lipoproteins in patients with normo- and hypertriglyceridemia treated with various hypolipidemic preparations (simvastatin and fenofibrate). Both preparations changed phospholipid composition of high-density lipoproteins and improved their functional activity. The differences in the phospholipid composition of high-density lipoproteins were probably related to lipolysis of triglyceride-rich lipoproteins catalyzed by lipoprotein lipase and, in particular, hepatic lipase.

Cerivastatin modulates antiatherogenic properties of high-density lipoproteins in patients with coronary heart disease and hyperlipidemia.

The effects of cerivastatin on antiatherogenic properties of high-density lipoproteins were studied in patients with coronary heart disease and hyperlipidemia. Apart from hypolipidemic effects, cerivastatin changed the phospholipid composition of high-density lipoproteins and improved their cholesterol-acceptor properties. This effect was most pronounced in the serum from patients with low content of high-density lipoprotein cholesterol.
