Objective To explore the effects and possible mechanism of baicalin on renal interstitial fibrosis in unilateral urethral obstruction (UUO) rat.Methods Forty male SD rats were randomly divided into the sham operation group,model group,baicalin group,benazepril group and baicalin+ benazepril group,8 rats in each group.The baicalin group received the gavage of baicalin 40 mg · kg-1 · d 1,the benazepril group received the gavage of benazepril suspension 10 mg · kg-1 · d-1,the rats baicalin+ benazepril group received the gavage of baicalin 40 mg · kg-1 · d 1 and benazepril suspension 10 mg · kg-1 · d-1,the model group and sham operation group were given the same volume of normal saline.Rats were sacrificed in each group on 14,21,28 d after model construction and the kidney sample was obtained.Immunohistochemistry was used to detect the expression of TGF-β1 and α-SMA.Results Compared with the sham operation group,the TGF-β1 and α-SMA expression levels of renal tissue in the model group were significantly increased(P＜0.05),compared with the model group,the TGF-β1 and α-SMA expression levels on 14,21,28 d of model construction in the baicalin group,baicalin+ benazepril group and benazepril group were decreased to different extents (P＜0.05).But the TGF-β1 and α-SMA levels at each time point had no statistical difference among the baicalin group,benazepril group and baicalin+benazepril group(P＞0.05).Conclusion Baicalin may delay the progress of renal interstitial fibrosis in UUO rat by down-regulating the TGF-β1 expression and reducing α-SMA expression.

Objective To explore the relationship between organizational justice and turnover intention among nurses of tertiary hospitals and to provide implications for human resource management.Methods Totally 511 nurses were recruited from four tertiary hospitals of Jinan City and investigated with Organizational Justice Questionnaire and Turnover Intention Scale.Results The average scores of turnover intention and organizational justice were (2.46±0.61) and (3.55±0.62),respectively.Distributive justice and informational justice were significant predictors of turnover intention.Conclusions The turnover intention of nurses in tertiary hospitals is high.It is beneficial for mitigating nurses' tumover intention to improve their organizational justice,apply post management and performance appraisal model.

Objective To investigate the effects of silybin-phosphatidylcholine compound (SPC) on H2O2-induced the production of nitric oxide (NO) and reactive oxygen species (ROS) in mouse macrophage.Methods Macrophage were collected in abdominal cavity of 6-8 week Kunming mouse,and cultured macrophage(2?108 L-1) were divided into control and SPC group randomly.Macrophage in control group were added into the same volume(0.1 mL) of 9 g/L sodium chloride.Macrophage in H2O2 group were added into a single bolus of H2O2 (1 mmol/L H2O2) for 30 min,while macrophage in SPC group were preincubated with different concentration of SPC for 2 h followed by a 30 min incubation with 1 mmol/L H2O2.Immunocytochemistry were used to measure the contents of inducible nitric-oxide synthase(iNOS),NO production was determined by Griess reactive, ROS was determined by DCFH-DA Fluorescence probe.Results The production of NO in H2O2 group markedly higher than that in control group(P

Objective To investigate the effect of neutral amino acid on preventing Parkinson disease.Methods Mice were injected with L-Valine,L-Pheylalanine,D-Valine or L-Lysine before or after paraquat administration,by which prakinsonian mouse model was constructed.The paraquat immunoreactivity was observed within nigral cell bodies.Then neurodegeneration and ?-synuclein aggregation were observed by immunohistochemistry and Western blot.Results Paraquat immunoreactivity was abolished by the administration of L-Valine,L-Pheylalanine before paraquat exposure.Pre-treatment with these two amino acids also protected the paraquat-induced loss of nigrostriatal dopaminergic cells and formation of thioflavine S-positive aggregates.In contrast, paraquat-induced toxicity was unaffected if animals were injected with these two amino acids after paraquat exposure or pre-treated with D-Valine or L-Lysine.Conclusions L-type neutral amino acids such as L Valine and L-Pheylalanine can prevent paraquat-induced neurodegeneration and a synuclein pathology through a competitive inhibition mechanism with stereospecificity in the central nervous system (CNS).Neutral amino acid could protect the dopaminergic neuron in substantia nigra and may prevent Parkinson disease.

Objective To study risk factors of cardiovascular disease (CVD) and status of bone mineral density (BMD) in women with hypoestrogenism.Methods From Jul 2011 to April 2013,a total of 256 women with hypoestrogenism in the First Affiliated Hospital of Shanxi Medical University were enrolled in this retrospective study,which were divided into four groups:133 women in ppausal group,25 women in premature ovarian failure (POF) group,67 women in menopausal transition group and 31 women in premature ovarian failure transition group.General statue,CVD risk factors and BMD were compared among four groups.General statue include menopausal period,menopausal symptoms (Kupperman Index),CVD risk factors include body mass index,blood pressure,waist circumference,waist-hip ratio,blood lipids and glucose,BMD include left hip,lumbar spine bone mineral density and T or Z value.Results (1) The median menopausal period were 3.4 years in postmenopausal group and 3.6 years in premature ovarian failure group,which did not show no statistical difference (P ＞ 0.05).Kupperman Index in four groups were 12 in postmenopausal group,9 in POF group,9 in menopausal transition group and 8 in premature ovarian failure transition group,which reached statistical difference (P ＜ 0.05).(2) The difference of body mass index (BMI),waist circumference,waist-hip ratio,diastolic blood pressure were no statistically significant among four groups(P ＞ 0.05) ; the systolic blood pressure in four groups were 120,110,110,110 mm Hg (1 mm Hg =0.133 kPa),their differences were statistically significance (P ＜ 0.05); the high-density lipoprotein (HDL-C) was 1.6 mmol/L in postmenopausal group,and 1.3 mmol/L in premature ovarian failure transition group,their differences were all statistically significance (P ＜ 0.05) ; the difference of the fasting plasma glucose (FPG) was not statistically different in 4 groups (P ＞0.05).(3) The abnormal rate of lower bone mass in lumbar spine were 57％ (46/81) postmenopausal group,8/15 in POF group,32％ (9/28) in menopausal transition group,12/19 in premature ovarian failure transition group,and osteoporosis was 9％ (7/81),3/15,1％ (3/28)and 0 respectively,their differences were statistically different (P ＜ 0.05) ; the abnormal rate of BMD of left hip and lumbar spine of 11/15 and 12/16 in POF group was higher than 65％ (53/81) in postmenopausal group.In the mean time,the abnormal rate of BMD of left hip and lumbar spine were,12/19 and 10/20 in premature ovarian failure transition group,which were significantly higher than 43％ (12/28) and 39％ (12/31) in the menopausal transition group.Conclusions The menopausal symptoms resulting from hypoestrogenism in natural postmenopausal women are mostly remarkable.The decrease of BMD in lumbar spine is more significant than that of left hip among postmenopausal women.Women with earlier menopause was prone to cause the changes of blood fat and abnormal of BMD,especially HDL-C decreased significantly compared with those natural postmenopause,it is more likely to cause CVD and osteoporosis.

To explore new agents of quinolone derivatives with high antibacterial activity, 7-(4-alkoxyimino-3-methyl-3-methylaminopiperidin-1-yl)quinolones were designed and synthesized, and their activity against gram-positive and gram-negative strains was tested in vitro. Sixteen target compounds were obtained. Their structures were established by 1H NMR, HRMS and X-ray crystallographic analysis. Compounds 14k and 14m-14o show good antibacterial activity against the tested five gram-positive strains and five gram-negative strains (MIC: 0.25-16 micromg x mL(-1)), of which the most active compound 14o is 8-fold more potent than levofloxacin against S. pneumoniae (MIC: 4 microg x mL(-1)), and comparable to levofloxacin against S. aureus, S. epidermidis, E. faecalis and E. coli (MIC: 0.25-1 microg x mL(-1)), but generally less potent than gemifloxacin.
