Objective To investigate compliance and influencing factors of hand hygiene (HH)among health care workers(HCWs).Methods From November 2014 to February 2015,implementation of HH among HCWs in 15 clinical departments in a hospital was investigated through questionnaires,the effect of HH purpose on HH behav-ior of HCWs was analyzed with multivariate logistic regression method.Results A total of 364 HCWs were investi-gated,245 (67.31% )of whom implemented HH well. Univariate analysis revealed that implementation of HH a-mong HCWs of different occupations,education levels,and HH purpose were all significantly different (all P<0. 05). Multivariate logistic regression analysis showed that HH purpose as well as HH compliance were both signifi-cantly different (P= 0.042). Compared with HH purpose of self-protection among HCWs,HCWs with HH pur-pose of cross-infection prevention had better HH behavior (OR,2.17[95% CI,1.29-3.65]).The top five objective factors influencing HCWs'HH implementation were as follows:lack of warm water in winter (70.73% ),heavy workload,had no time (61 .38% ),skin irritation caused by disinfectant or hand sanitizer (54.88% ),without hand dryer (47.56% ),and use disposable gloves (45.12% ).Conclusion On the basis of improving HH facilities,chan-ging HCWs'awareness of HH only for self-protection may be an another way to improve HH compliance among HCWs.

Objective To study the significance of S100A12 in patients with acute pancreatitis (AP).Methods 139 patients with AP were divided into the severe acute pancreatitis (SAP) and moderate acute pancreatitis (MAP) groups.61 patients in the SAP group were further subdivided into the infection group (n =32) and the non-infection group (n =29) based on the presence/absence of secondary infection.Serum samples of these patients were collected on the 3rd,7th and 14th day after treatment.ELISA was used to determinate the S100A12,IL-1 β and IL-6 levels in serum.The area under ROC was used to evaluate the predictive role of S100A12,IL-1β,IL-6 and CRP for infection in patients with SAP.Results The S100A12,IL-1β and IL-6 levels in SAP patients were markedly higher than those in MAP patients and normal controls on the 3rd,7th and 14th day after treatment.These levels decreased toward normal range in MAP patients.They were persistently high in SAP patients after treatment for 7 days,but decreased significantly after 14 days.The serum levels of S100A12,IL-1β,IL-6 and CRP were significantly higher in the infection subgroup(647.5 ± 300.1,155.9 ±48.5,95.7 ±25.5,166.8 ±53.0) than the non-infection subgroup(249.0 ± 176.3,108.0 ± 46.1,64.0 ±38.5,117.9 ±34.9) (P ＜0.05).The sensitivity and specificity of serum S100A12 in diagnosing secondary infection in SAP were 96.8％ and 83.3％,which were higher than those of serum IL-1β,IL-6 or CRP.Conclusion The level of S100A12 was associated with systemic inflammatory response syndrome (SIRS) in AP,and it may serve as a new marker in early diagnosis of SAP and in secondary infection in SAP.

This study was aimed to observe the effect ofZi-Bu Pi-Yin Recipe (ZBPYR) on the mRNA expressions of NMDA receptor subunits NR1, NR2A, NR2B in different brain regions of spleen-yin deficiency Alzheimer's Disease (AD) model rats. The levels of NR1, NR2A, NR2B mRNA expressions were detected by using RT-PCR method. The results showed that the levels of NR1, NR2A, NR2B mRNA expressions of AD group and spleen-yin deficiency AD group decreased significantly (P < 0.05). The levels of NR1, NR2A, NR2B mRNA expressions of ZBPYR treatment group increased significantly (P < 0.05). It was concluded that the expression levels of NMDAR mRNA in different brain regions of the ZBPYR treatment group increased significantly, which indicated that ZBPYR may up-regulate the protein expressions of NMDAR by increasing the expression levels of NMDAR mRNA, thereby to play the anti-dementia effect.

AIM:To explore the molecular mechanism through which curcumin reverses hepatocyte growth factor (HGF)-induced resistance to gefitinib in lung cancer cells.METHODS:The methods of MTT assay, wound healing assay and Western blot were used to observe the effects of HGF, curcumin and gefitinib on the migration, drug susceptibility, epithelial-mesenchymal transition, and related signaling pathways in the PC9 lung cancer cells.RESULTS:HGF reduced susceptibility of the PC9 cells to gefitinib, and curcumin significantly reversed HGF-induced resistance to gefitinib.HGF induced migration and epihelial-mesenchymal transition, and promoted c-Met/AKT/mTOR pathway activation in the PC9 cells.Gefitinib alone did not prevent the above activities.However, combined with curcumin, gefitinib prevented the above activities.CONCLUSION:Curcumin reverses HGF-induced resistance of the PC9 cells to gefitinib by preventing epithelial-mesenchymal transition and inhibiting c-Met/AKT/mTOR activation.

OBJECTIVETo observe the effect of nourishing yin removing fire Chinese herbs (NYRF-CH) on the gene expression of hypothalamic growth hormone secretion peptide (Ghrelin) and its receptor growth hormone secretion peptide receptor 1alpha (GHSR1-alpha) at the puberty onset of danazol induced female precocious rats.

METHODSForty female SD rats were randomly divided into 4 groups, i.e., the normal group (N), the model group (M), the normal saline intervention group (NS), and the NYRFCH intervention group (NI), 10 in each group. 300 microg danazol was subcutaneously injected to all rats except those in the N group to prepare precocious rat model. NYRFCH and normal saline was respectively administered to rats in the NI and the NS group from the 15th day old for 7-10 days. No treatment was given to rats in the N group. Time of rats' vulva opening was recorded. Ovary index and uterus index were calculated. Peripheral blood levels of estradiol (E2), follicle stimulating hormone (FSH), and luteinizing hormone (LH), and hypothalamic contents of gonadotropin releasing hormone (GnRH) as well as the gene expression of hypothalamic Ghrelin and GHSR1-alpha were determined. Results Compared with the N group, the vulva opening time was advanced in the model group; peripheral blood levels of E2 and LH, uterus index, hypothalamic contents of GnRH increased; peripheral blood FSH levels and mRNA levels of hypothalamic Ghrelin and GHSR1-alpha decreased (P < 0.05, P < 0.01). Compared with the M group and the NS group, the vulva opening time was not advanced in the NI group; peripheral blood levels of E2 and LH, uterus index and hypothalamic contents of GnRH obviously decreased (P < 0.05, P < 0.01); mRNA levels of hypothalamic Ghrelin and GHSR1-alpha increased (all P < 0.01). But there was no statistical difference in the hypothalamic contents of Ghrelin, or the number and activity of GHSR1-alpha (P > 0.05).

CONCLUSIONNYRFCH had regulatory effect on regulating hypothalamic Ghrelin and GHSR1-alpha at gene transcription levels.
