The county health service planning is a very important link in county health reform, the planning process involves many professional problems, such as the setting of total bed number and proportional allocation. To solve these problems, it is needed to find a feasible method. Methods:Using operational research theory and method of linear programming to estimate whether the resource amount could satisfy the needs, and further explore the problem of the health resources in county-township-village. Results:(1) Operational research method could be used to judge whether the total bed amount and rate in county and township are suitable;(2) but linear programming to allocate capital budget model still exist some defects. The blind expansion and the pursuit of institution beds scale expansion are the phenomenon at present stage, the linear programming method could effectively help to determine whether these resources is really insufficient or excess. The method could be expanded to urban areas so as to supervision whether health resources are over expanded.

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 observe the promoting effect of psychotherapy on hypertension patients.Methods100 hypertension patients were randomly divided into the intervention group(52 cases) and control group(48 cases).The intervention group was given drug therapy and psychotherapy while the control group was treated with drug therapy and health education.Blood pressure and scale of Symptom Checklist-90(SCL-90) were used to assess the treatment results.ResultsThere were no significant differences between the two groups in systolic blood pressure(SBP) and diastolic blood pressure(DBP) before the treatment(P>0.05).After interventions,SBP and DBP of the two groups decreased significantly,but the intervention group was more effective than the control group(P<0.001).The intervention group had lower scores of SCL-90 than the control group(P<0.05).ConclusionPsychotherapy can effectively improve the negative moods and mental health of hypertension patients.

Objective To investigate the effect of glutamic acid (monosodium glutamate,MSG) on Tourette's syndrome (TS). Methods These rats were divided into 2 groups: one group with acute intracerebroventricularly injection (ICV) of MSG or artificial cerebrospinal fluid (CSF), and another group with chronic administration of MSG in a dose of 40 mg/kg in drinking water everyday. Observers who were blind to the two- part subjects assessed the scores of TS- like stereotyped locomotion. Results 1. These groups of 100 ?g or 200 ?g glutamic acid may induce significant TS - like stereotyped locomotion ( P

Objective To investigate the regulation mechanism of dendrobium nobile polysaccharides (DNP) for nuclear factor kappa B (NF-κB) signal pathway in focal cerebral ischemia/reperfusion rats.Methods According to the digital random method,90 SD rats were divided into 6 groups:sham operation,model,DNP low-dose (DL,50 mg/kg),moderate-dose (DM,100 mg/kg) and high-dose (DH,200 mg/kg),and nimodipine (10 mg/kg) groups (n =15 in each group),and according to the random number method,selecting 5 in each group for the corresponding index detection.A focal cerebral ischemia/reperfusion model in SD rats was induced by middle cerebral artery occlusion.The improvement effect of DNP on rat neurological deficit (Bederson behavioral score) and brain water content,and infarct volume were observed.Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of proinflammatory cytokine tumor necrosis factor-α (TNF-α) and interleukin-β (IL-1 β) in brain tissue.Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect microglial cell marker BCL-2-related protein A1 α (A1) and astrocyte marker glial fibrillary acidic protein (GFAP) mRNA transcription levels.Western blot was used to detect the NF-κB signaling pathway phosphorylated IκBα protein and nuclear p65 protein expression levels.Single factor variance analysis was used to compare the measurement data among the groups.Results (1) There were significant differences in the neurological deficit score,brain water content,cerebral infarction volume,brain tissue TNF-α and IL-1β levels,A 1 and GFAP mRNA transcription levels and phosphorylated IκBα protein and nuclear p65 protein levels among the 6 groups (F =22.24,8.699,33.89,19.26,27.53,109.5,15.28,66.86,and 41.63,respectively (all P ＜ 0.01).(2) The neurological deficit score,cerebral water content,and cerebral infarction volume in the model group were 2.8 ± 0.3,86.1 ±3.8％,and 31.0 ±4.5％,respectively.The TNF-α and IL-1β levels,A1 and GFAP m RNA transcription levels in brain tissue,and phosphorylated IκBα protein and nuclear p65 protein levels were increased significantly compared with those in the sham operation group.There were significant differences (all P ＜0.01).(3)The above indices in the DH group were 1.5 ± 0.5,72.9 ±5.4％,and 17.5 ±4.1％,respectively.Compared with the model group (including TNF-α and IL-1 β levels,A1 and GFAP mRNA transcription levels and phosphorylation of IκBα protein and nuclear p65 protein levels in brain tissue).There were significant differences (all P ＜ 0.05).Compared with the nimodipine group,there were no significant differences (all P ＞ 0.05).Compared with the sham operation group,except for there were no significant difference in brain water content,phosphorylated IκBα protein and nuclear p65 protein (P ＞0.05),there were significant differences in other indices (all P ＜ 0.05).(4) Compared with the model group,only IL-1 β and phosphorylated IκBα protein levels were decreased significantly in the DM group,there were no significant differences in other indices (all P ＞ 0.05).Compared with the sham operation group,there were significant differences in other indices (all P ＜ 0.05).(5) Compared with the model group,there were no significant differences in other indices in the DL group (P ＞ 0.05).Compared with the sham operation group,there were significant differences in all indices (all P ＜ 0.05).Conclusion Highdose DNP may reduce focal cerebral ischemia/reperfusion injury in rats.The mechanism of may be associated with the inhibition of activation of early NF-κB signaling pathway.The effects of low-and moderate-dose DNP on reducing inflammatory brain damage of focal cerebral ischemia/reperfusion may be not obvious.

Epidermal growth factor receptor (EGFR) is found to express at high levels in a variety of solid tumors including gliomas. This study was to examine the effect of an EGFR-tyrosine kinase inhibitor (AG1478) alone or in combination with cisplatin (CDDP) on the growth of glioma cells (U87). U87 glioma cells were treated with AG1478 (10 μmol/L) or CDDP (25 μmol/L) as a single agent or in combination for 24 or 48 h. The expression of EGFR and the components in its downstream signaling pathway [extracellular signal-regulated kinase (ERK), protein kinase B (AKT)] in U87 glioma cells was detected by Western blotting. Cell growth, cell cycle distribution and cell apoptosis were determined by MTT method and flow cytometry, respectively. The results showed that CDDP could induce the activation of EGFR and the components in its downstream signaling pathways in a concentration-dependent manner. The combined treatment of AG1478 with CDDP could inhibit the proliferation of U87 glioma cells, arrest the cell cycle and promote cell apoptosis. In the EGFR signaling pathway, AG1478 decreased the phosphorylation of ERK, AKT and EGFR in U87 glioma cells. It was concluded that the combined treatment of AG1478 and CDDP may exert synergistic inhibitory effects on the growth of glioma cells by suppressing the activities of EGFR, AKT and ERK.

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.

OBJECTIVETo study the effect of Wu-He Dipsacus asper (WHDA), Traditional Chinese Medicine, injection on mice-aging model induced by D-galactose.

METHODSForty-eight Kunming mice (24 male and 24 female) were randomly divided into control group, model group, positive control group, 7.2 g/kg WHDA group, 3.6 g/kg WHDA group and 1.8 g/kg WHDA group with eight in each group. The model was induced through injecting D-galactose into peritoneal cavity and Morris water maze was used to detect the learning and cognitive ability of mice. The skin hydroxyproline, brain tissue malondialdehyde (MDA), lipofuscin (LP), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels of mice were detected; the IL-2 and IL-6 levels in serum of mice were detected by using double antibody sandwich ELISA method.

RESULTSEach WHDA group was significantly reduced in latency period compared with the model group during Morris water maze test (P < 0.05) and the number of mice in model group through the platform was less than other mice in each group (P < 0.05). The levels of MAD and LP of the control group and each WHDA group were less than model group in the detection of heart, brain tissue oxidation index (SOD, MAD, LP and GSH-Px, P < 0.05). The activity of SOD and GSH-Px in the control group and each WHDA group was significantly higher than that in the model group (P < 0.05). The skin hydroxyproline content of mice which had been injected with D-galactose was significantly lower than that in the control group (P < 0.05) and the skin hydroxyproline content of mice of WHDA group was significantly higher than that in the model group (P < 0.05). The IL-2, IL-6 levels in serum of mice in WHDA group were significantly higher than those in the control group and the model group (P < 0.05) and the IL-2, IL-6 levels in serum of mice in the model group were lower than those in the control group (P < 0.05).

CONCLUSIONThe effective constituents of WHDA have a variety of biological activity which can have a good effect on anti-aging by different ways, improving learning and memory function, eliminating free radicals antioxidant, and enhancing the body immunity and other aspects.
