OBJECTIVE To investigate the behavioral and ultrastructural changes of intrathecal administration of different concentrations of ropivacaine for 12 h. METHODS Thirty male SD rats were randomly divided into 5 groups (6 rats in each group):group N (control), group A (ropivacaine 0.25%), group B (ropivacaine 0.5%), group C (ropivacaine 0.75%),and group D(More)
Andrographolide (Andro) suppresses proliferation and triggers apoptosis in many types of cancer cells. Taxifolin (Taxi) has been proposed to prevent cancer development similar to other dietary flavonoids. In the present study, the cytotoxic and apoptotic effects of the addition of Andro alone and Andro and Taxi together on human prostate carcinoma DU145(More)
OBJECTIVE It is well documented that both work stress and work motivation are key determinants of job satisfaction. The aim of this study was to examine levels of work stress and motivation and their contribution to job satisfaction among community health workers in Heilongjiang Province, China. DESIGN Cross-sectional survey. SETTING Heilongjiang(More)
Cumin seeds (Cuminum cyminum L.) have been commonly used in food flavoring and perfumery. In this study, cumin essential oil (CuEO) extracted from seeds was employed to investigate the anti-inflammatory effects in lipopolysaccharide- (LPS-) stimulated RAW 264.7 cells and the underlying mechanisms. A total of 26 volatile constituents were identified in CuEO(More)
OBJECTIVE To investigate the effect of electroacupuncture (EA) of "Baihui" (GV 20) and "Yongquan" (KI 1) on the expression of amyloid beta protein (Abeta) and low density lipoprotein (LDL) receptor-related protein 1 (LRP 1) in the hippocampal sulcus microvessels in amyloid precursor protein (APP) 695 V717 I transgenic mice, so as to study its mechanism(More)
OBJECTIVE To investigate the ultrastructural basis underlying electroacupuncture (EA) induced improvement of Alzheimer disease (AD) in transgenic mice. METHODS Twelve APP 695 V 717 I transgenic mice were randomly divided into model group and EA group; and other 6 negative transgenic mice (C 57 BL/6 J) were made up of normal control group. After 3 months(More)
BACKGROUND Although China experienced great improvement in their health system, disputes between patients and doctors have increasingly intensified, reaching an unprecedented level. Retrospective analysis of medical malpractice litigation can discover the characteristics and fundamental cause of these disagreements. METHODS We analyzed medical malpractice(More)

OBJECTIVE To observe the effect of electroacupuncture (EA) therapy on the intraneuronal Abeta1-42 and dysfunction of autophagy pathway, so as to reveal its mechanism underlying improvement of Alzheimer's disease (AD). METHODS APP 695 V 717 I transgenic female mice were randomly divided into model group (n = 6) and EA group (n = 6); and C 57 BL/6 mice were(More)
