Pathological pain or clinical pain is caused by tissue and nerve injuries,and is usually chronic and mainly divided into inflammatory pain and neuropathic pain. Pathological pain is typically characterized by hyperalgesia (increased responsiveness to noxious stimuli) and allodynia (painful responses to normally innocuous stimuli). The MAPKs are a family of evolutionally conserved molecules that play a critical role in cell signaling,consisting of extracellular signal-regulated kinase (ERK),p38,and c-Jun N-terminal kinase (JNK),which play an important role in neural plasticity of pathological pain. Inhibition of MAPKs alleviates inflammatory pain and neuropathic pain in different animal models. It is very important to study the inhibition of MAPKs as a therapeutic approach to treating pathological pain. All the studies suggest that MAPKs is a promising therapeutic target for pathological pain.

Objective:To evaluate the effect of Indomethacin suppositories on albumin concentration and insulin resistance of post-operation patients with serious intra-abdominal infection.Methods:38 post-operation patients with serious intra-abdominal infection were divided into two groups randomly.One as treatment group(n=19)and the other as control group(n=19).Albumin,blood glucose,fasting insulin concentration were measured At 72 hours after the operation and 144 hours.Insulin resistance index was calculated using the homeostasis model assessment(HOMA).Finally,the results of two groups were analyzed.Results:The albumin concentration of Indomethacin group at 72 hours was significantly higher than that after 72 hours,Insulin resistance of 144 hours was lower than the control group(P0.05).Conclusion:Postoperative abdominal infection using indomethacin suppository can significantly reduce insulin resistance,and significantly reduced the decomposition of albumin.

Objective The aim of this study was to analyze of the prevalence of Norovirus in the foodborne disease surveillance population in Baiyin City in 2015,and provide scientific basis for the prediction,early warning,prevention and control of foodborne diseases caused by Norovirus.Methods A questionnaire survey was conducted on the cases of foodborne disease surveillance.Fecal specimen were collected,and Norovirus GⅠ and GⅡ were detected by real time fluorescence quantitative polymerase chain reaction.Results Three hundred and forty-four foodborne disease cases were reported,78 cases were positive,and the detection rate was 22.7％.Five cases were positive for Norovirus GⅠ,and 71 cases for GⅡ.Two cases were positive for both GⅠ and GⅡ.Forty-six cases were male and 32 cases were female.The oldest patient was 83 years old,and the youngest was only 3 months with an average age of 20.3.Conclusion Norovirus was one of the main foodborne pathogens in the city,and the main epidemic was GⅡ in autumn and winter.Public education and health monitoring should be strengthened.

Serum biomarkers have important roles in predicting severity, deterioration of early neurological function, and outcome in acute ischemic stroke.Understanding the type of these serum biomarkers, mechanism of action, and correlation with acute ischemic brain injury may help predict early outcomes and guide treatment in patients with acute ischemic stroke.

Objective To explore the protective effect of rhG-CSF given intranasally on cerebral infarct rats by observing the neurological dysfunction and the expression of Fas ligand (FasL) in hippocampus of cerebral infarct rats.Methods Middle cerebral artery occlusion(MCAO) model rats were established by nylon strand,reperfuse 2 hours later,and give rhG-CSF through subcutaneous and intranasal way.The rats were divided into the nermal group,the sham-operated control group(sham),MCAO group,MCAO+NS given intranasally group(NS),MCAO + rhG-CSF given subcutaneously group,and MCAO + rhG-CSF given intranasally group each group had 6 rats. At the time of 3d after reperfusion,neurological severity scores (NSS) test was performed and the expression of FasL was detected via immunohistochemical staining in collateral hippocampus. Results Neurological dysfunction appeared in all groups except for the normal and the sham group. The dysfunction of the MCAO and the NS group was the most serious,the NSS was the highest(10.20±1.85,10.30±1.76),the number of FasL positive cells was the most(41.17±3.25,41.00±2.76),and there was no obvious difference between the two groups ( P ＞0.05);the NSS and FasL positive cells decreased in the subcutaneous group(5.67±1.32,P ＜0.01;32.67±1.97,P ＜0.01) and decreased further more in the intranasal group(4.00±0.93,P ＜0.05;19.50±1.05,P ＜0.01).Conclusions rhG-CSF given intranasally can relieve the neurological dysfunction of cerebral infarct rats,and brain cells are thereby protected by resisting the expression of FasL.

Objective:To analyze the characteristic peaks of gypsum fibrosum from authentic product area Hubei Yingcheng via X-ray diffraction. Methods:The fingerprint and common peaks of gypsum fibrosum from different areas were analyzed via X-ray diffrac-tion, and the characteristic peaks of gypsum fibrosum from authentic product area Hubei Yingcheng were identified Results:The finger-prints of X-ray diffraction of gypsum fibrosum from different areas were obtalned. Sixteen common peaks were determined, and two characteristic peaks of gypsum fibrosum from authentic product area Yingcheng were determined via X-ray diffraction with interplanar spacing of 1. 68 and 1. 51, respectively. Conclusion:The determination of two characteristic peaks of gypsum fibrosum from authentic product area Hubei Yingcheng can distinguish gypsum fibrosum from the other areas and provide basis for the quality evaluation of gyp-sum fibrosum.

Hypertension is a kind of chronic disease effecting many population, and its prevalence has a rising trend with the age. It keeps in a increasing trend in chinese population, and follows high rates of prevalence, mortality, morbidity and three low rates of wareness, treatment, control. Hypertension is caused by a number of factors, and its incidence is closely related with unhealthy diets. Its incidence may be decreasing gradually by changing lifestyles, taking healthy and reasonable diet. To provide some basic data of healthy lifestyles and diet for people, describe and summarize the relation of hypertension and diets in this article.
