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.

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.

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 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 To analyze clinical manifestation and identify prognostic factors in patients with acute respiratory distress syndrome (ARDS) caused by cytomegalovirus (CMV) pneumonia after kidney transplantation.Methods Fifty five kidney transplant recipients' data were analyzed in a case-control study of patients with a primary discharge diagnosis of ARDS caused by CMV pneumonia.Results The mortality of ARDS after kidney transplantation was 56.4%;when association with mechanical ventilation,it was 72.5%.In multivariate Logistic regression analysis,numbers of complications (odds ratioOR2.60,95% confidence intervalCI1.00~6.76),severity of diffuse infiltrates in chest X-ray (OR 11.83,CI 1.14~123.07),mechanical ventilation (OR 11.83,CI 1.14~123.07) were independent risk factors to death.Conclusion Even in modern era,kidney transplant recipients with ARDS after kidney transplantation are still at high risk for death.Numbers of complications,severity of diffuse infiltrates in chest X-ray,mechanical ventilation are associated with poor outcomes.

Objective To optimize the extracting condition of total isoflavones from Fructus Sophorae by subcritical water extraction.Methods Taking isoflavones yield as index and genistin as control,the technology parameter of subcritical water extraction of Fructus Sophorae isoflavones was optimized by single factor and orthogonal experiment.Results The yield of Fructus Sophorae total isoflavones in the extracts was 23.3% at 130 ℃ for 45 min with the liquid-solid ratio of 12.5 mL/g.Conclusion Compared with traditional extracting methods,subcritical water extraction is a new developing technology in recent years.Its advantage is fast,good-selective.

Objective To compare the effect of myomectomy and uterine artery embolization in the treatment of uterine fibroids .Methods 158 patients who were pathologically diagnosed uterine fibroids were randomly divided into the uterine artery embolization group and myomectomy group ,79 cases in each group .The blood loss 3 days after operation,pelvic pain and pressure symptoms ,hospitalization time,follow-up and time of normal activity were recorded and compared.Results The pelvic pain,pressure symptoms,hospitalization time,cure rate,incidence rate of compli-cations and recurrence rate of the two groups had no statistically significant differences ( t=1.21,0.97,1.06,χ2 =0.98,1.21,1.32,all P>0.05).The postoperative bleeding score ,time of return to normal activity in the uterine artery embolization group were (5.8 ±0.5) points,(9.8 ±1.8) d,which were better than those of the myomectomy group[(4.9 ±0.4)points,(25.9 ±5.1)d](t=3.76,5.98,all P<0.05).Conclusion The effect of the myomec-tomy and uterine artery embolization treatment for uterine leiomyoma is similar ,and both have high efficiency and safe-ty,but the uterine artery embolization treatment has less impact on the body of patients .

Objective To investigate the effect of Miles laparoscopic sigmoid colostomy surgery for elderly patients with colorectal cancer .Methods The clinical data of 78 elderly patients with colorectal cancer underwent surgery were chosen .According to the different operation method , they were randomly divided into the observation group and control group ,39 cases in each group .The observation group was treated with laparoscopic Miles ,and the control group underwent surgery for abdominal Miles .The safety,efficacy,early complications of the two groups were analyzed and compared .Results The incidence rate of postoperative complication , excellent rate of ostomy surgery 6 months after operation in the observation group were 5.13%, 66.67%, respectively, which were better than 38.46%,20.51%in the control group (χ2 =12.70,9.69,all P<0.05).The defecate feeling of the observation group was better than that of the control group (χ2 =29.40,P<0.05).The difference of patients'quality of life and physical function between the two groups was statistically significant (t=3.30,P<0.05).Conclusion The clinical effect of laparoscopic sigmoid colostomy surgery Miles in the treatment of elderly patients with colorectal cancer is bet -ter than traditional open surgery ,it has obvious practical significance such as reducing the short and long term compli -cations and improving the quality of life of patients .

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.
