Objective:To investigate relationships between the single nucleotide polymorphisms(SNPs) of interleukin-1B(IL-1B) and variable number of tandem repeat (VNTR)of interleukin-1RN(IL-1RN) promoter genes and susceptibility of the patients with gastric adenocarcinoma or the patients with gastric adenocarcinoma to helicobacter pylori (Hp) infection.Methods:The SNPs of the IL-1B(-31C/T and -511C/T) were determined by gene chip and The VNTR of IL-1RN were determined by agrose gel electrophoresis with a total of 130 cases of gastric adenocarcinoma and 142 healthy controls.The sera concentrations of IgG,IgM and IgA of Hp antibodies were measured by ELISA in all cases and controls.Results:H.pylori infection was detected in 69.2% of 130 patients and 46.5% of 142 controls (P=0.007,odds ratio [OR]=2.53).Frequencies of IL-1B-31TT genotype in patients with gastric adenocarcinoma or in patients with pooly-differentiated gastric adenocarcinoma were significantly higher than those in healthy controls or in well-differentiated groups,(P

Objective To explore the impact of transformational leadership on nurses'professional quality of life and organizational commitment by hierarchical linear modeling (HLM).Methods A total of 44,6 clinical nurses were investigated with demography questionnaire,professional quality of life questionnaire,organizational commitment questionnaire and transformational leadership questionnaire.Results The transformational leadership had positive predict ability to the nurses'compassion satisfaction,secondary traumatic stress and organizational commitment.The transformational leadership had negative predict ability to burnout.The transformational leadership could adjust the relationship between compassion satisfaction,secondary traumatic stress and organizational commitment.Conclusions The transformational leadership provides theoretical reference for nursing managers to effectively lead the team,increase professional life quality of the nurses,and then improve the level of organizational commitment of the nurses.

?Dry eye is a common eye disease around the world, which has highly incidence. Although there are many treatment measures for dry eye, the clinical effect is not satisfactory. There is a close relationship between inflammation and dry eye, so the researchers pay more attention on anti -inflammatory therapy, such as fluorometholone. To explore the effect of anti -inflammatory medicine on dry eye, put forward the problems and shortcomings as well, lay the foundation for further study, and provide a strong theoretical basis for the clinical use of anti-inflammatory drugs in the treatment of dry eye, the author summarizes the clinical and experimental research progress of fluorometholone on dry eye in China and abroad.

Objective To investigate the anti-tumor effect and mechanism of tamoxifen on rat C6 glioma cells. Methods C6 cells were cultured in Dulbecco's modified Eagle's medium (DMEM) with 3% fetal calf serum (FCS), and treated with tamoxifen of different concentrations, i.e. group A (1.25μmol/L), group B (2.50 μmol/L), group C (5.00 μmol/L), group D (10.00 μmol/L), group E (20.00 μmol/L) and control group (0.00 μmol/L). Morphological changes, MTT assay and 5-bromo-2'-deoxyuriding labeling ratio were assessed. Apoptosis was observed by flow cytometry. Results C6 cells treated with different doses of tamoxifen for 24, 48, and 72 hours became irregular in shape, while cells treated with vehicle grew normally. MTT assay showed that tamoxifen did not suppress C6 cell growth until 72 hours after treatment. Seventy-two hours after treatment, there were significant differences in cell viable rate between group A versus groups C, D and E; so did group B versus group D as well as group E (P<0.05). BrdU incorporation assay indicated significant difference of BrdU labbled index (BrdU LI) among groups A, C, E and control group 48 hours after treatment (P<0.05). And the BrdU LI decreased with the increased concentration of tamoxifen. Flow cytometry (FCM) showed significant difference between treated group and control group at 24, 48, and 72 hours after treatment (P<0.05). Conclusion Tamoxifen significantly suppresses the growth of C6 glioma cells in a time- and dose-dependent manner. The mechanism of tamoxifen suppressing C6 glioma cells may be inhibiting proliferation and inducing apoptosis. Therefore, tamoxifen can be a candidate as a chemotherapy agent for glioma.

Chinese patent medicine with double identity was a special phenomenon, and many preparations not only were prescription drugs but also over the counter ( OTC) drugs, which brought a lot of trouble. Based on statistics of list of OTC medicines of CFDA, related varieties, route of administration and functions of these drugs were searched. The causes of insufficient were analyzed and the potential risk was investigated. To ensure the safety of drug usage for the patient, risk management system should be set up by improving the technical requirements for registration, improving the drug labels and manuals, playing the role of pharmacists in pharmacy services and raising awareness of doctor and patient for these drugs.

OBJECTIVETo evaluate in vitro effect of abnormal savda munziq (ASMq) on the proliferation and apoptosis of human hypertrophic scar fibroblasts (HSFs).

METHODSHSFs were divided into six groups to receive different treatments as group A (blank control group), group B-E (ASMq in different concentration), and group F(5-Fu). Each group contains six specimens. The HSFs were cultured in vitro. After culture for 48 hours, the CCK8 test and flow cytometry methods were used to detect the proliferation, cell cycle and apoptosis.

RESULTSThe proliferation of HSFs in the B, C, D and E groups was inhibited at G2/M period, while it was inhibited at G0/S period in group F (P < 0.05). The inhibition effect of ASMq (0.1-1.0 mg/ml) on the fibroblasts enhanced in a concentration-dependent manner. Flow cytometry analysis with annexin V-FITC and PI staining confirmed the apoptotic. When HSFs were exposed to ASMq at 1.0 mg/ml (group E) for 48 h, the percentage of apoptotic cells increased to (43.7 +/- 2.58)%, which was significantly higher than that of blank control group (2.2 +/- 0.59)%. The induced apoptosis effect was also increased in a concentration-dependent manner.

CONCLUSIONASMq has a inhibitory effect on the proliferation and an enhancement effect on the apoptosis of fibroblast. ASMq could be used as an effective drug for treatment of hypertrophic scar.

OBJECTIVETo observe the effect of sesamin (Ses) on pulmonary vascular remodeling in rats with monocrotaline ( MCT)-induced pulmonary hypertension (PH).

METHODTotally 48 male Sprague-Dawley (SD) rats were fed adaptively for one week and then divided into the normal control group, the MCT group, the MCT +Ses (50 mg x kg(-1)) group and the MCT + Ses (100 mg x kg(-1)) group, with 12 rats in each group. The PH rat model was induced through the subcutaneous injection with MCT(60 mg x kg(-1)). After the administration for four weeks, efforts were made to measure the right ventricular systolic pressure( RVSP) and mean pulmonary artery pressure (mPAP) through right jugular vein catheterization, and isolate right ventricle( RV) and left ventricle( LV) +septum (S) and measure their length to calculate RV/ ( LV + S) and ratio of RV to tibial length. Pathologic changes in arterioles were observed by HE staining. Masson's trichrome stain was used to demonstrate changes in collagen deposition of arterioles. The alpha-smooth muscle actin (alpha-SMA) expression in pulmonary arteries was measured by immunohistochemisty. The total antioxidative capacity (T-AOC) and malondialdehyde (MDA) content in pulmonary arteries were determined by the colorimetric method. The protein expressions of collagen I, NOX2 and NOX4 were analyzed by Real-time PCR and Western blot.

RESULTAfter the administration for 4 weeks, Ses could attenuate RVSP and mPAP induced by MCT, RV/ (LV + S) and ratio of RV to Tibial length, alpha-SMA and collagen I expressions and remodeling of pulmonary vessels and right ventricle. Meanwhile, Ses could obviously inhibit the expressions of NOX2, NOX4 and MDA content and increase T-AOC.

CONCLUSIONSesamin could ameliorate pulmonary vascular remodeling induced by monocrotaline in PH rats. Its mechanism may be related to expressions of NOX2 and NOX4 expression and reduction in oxidative stress injury.

Two new polyesters, talapolyesters G-H (1-2) were isolated from the wetland soil-derived fungus Talaromyces flavus BYD07-13, and their structures were determined by NMR and MS spectroscopic data. The absolute configurations of the residues were determined by alkaline hydrolysis. The cytotoxicity against five tumor cell lines (HL-60, SMMC-7721, A-549, MCF-7 and SW480) of 1-2 was examined.
