Objective To Evaluate the status of health emergency situation of disease prevention and con-trol,and to provide the basis for scientific decision -making.Methods Using the method of cross -section investiga-tion,the present situation of public health emergency in 14 public health organizations in Xi'an was investigated,the data were analyzed by Spss18.0 and Microsoft Excel 2003.Results The emergency response system was constructed basically in Xi′an.The status of health emergency control situation was not optimistic,up to standard rate of emergency equipments was low.The emergency disposal system of public health emergencies was only 14.29% in perfect.Emer-gency team received professional training accounted for 55.63%.100% of the investigation agency made the depart-ment plans according to the higher plan,but only 64.29% of the agency can do the plan for a regular exercise and maintenance.88.32% of the team members received professional training to deal with the sudden departure time from receiving an average of 0.88 hours.28.57% counties agency had no pathogenic detection equipment,14.29% county agency waswithout physical and chemical testing equipment,and 7.14% county agency had no universal equipment.The training of epidemiology,inspection and emergency management were trained on average 1.38times a year,1.2 times and 0.63 times respectively.Conclusion The emergency disposal system of the disease control institution in Xi'an has been preliminarily formed,but in the personnel configuration and other aspects exist many deficiencies.Ef-fective measures should be adopted to strengthen construction of health emergency situation.

BACKGROUND: Ovariectomized animals usually are employed for the study of women osteoporosis while little is known about theenergy balance of ovariectomized animals. Many previous studies showed that soy isoflavone could decrease the hyperlipemia resulted by high-fat feed, and how about the effect of soy isoflavone on the energy metabolism in ovariectomized animals?OBJECTIVE: To explore the pathologic effect of soy extract and its active components on the energy metabolism in ovariectomized rats so as to provide adequate evidences for the primary rehabilitation and prevention of type Ⅱ diabetes mellitus, disturbance of lipid metabolism as well as hypertension and coronary atherosclerotic heart disease.DESIGN: A randomized and controlled trial with the experimental animals as subjects.SETTING: Laboratory of Cell and Biochemistry in a university.MATERIALS: Ninety Wistar rats (SFP grade, license code: scxk11-00-006) were randomized into 9 groups: normal group, sham group,model group, estrogen group, high-dose soy flavone group, low-dose soy flavone group, high-dose soy extract group, low-dose soy extract group and soy polysaccharide group, with 10 rats in each group.INTERVENTION: Except the rats in normal group and sham group,the bilateral ovaries of other rats were all removed. From one week after operation, body weight and daily food intake were detected once a week.Six weeks later, the rats were killed to calculate the forage transformation efficiency, measure body length, work out the body mass index (BMI),and separate the abdominal fat and weight.MAIN OUTCOME MEASURES: ①Effect of soy extract on the abdominal fat accumulation of ovariectomized rats. ②Effect of soy extract on food intake of ovariectomized rats. ③Effect of soy extract on forage transformation efficiency of ovariectomized rats.RESULTS: After ovariectomy, the food intake, body weight and BMI all raised, and the forage transformation efficiency increased, with abdominal fat accumulation. The changes of energy metabolism induced by ovariectomy were all weakened at different degrees in estrogen group, soy extract group and soy flavone group, while no influenced was found in soy polysaccharide group.CONCLUSION: The ovariectomized rats can be used as animal model of the climacteric fat women. The soy extract, with the effective component of flavonoid, can reduce the pathologic changes such as the increase of food intake, body weight and forage transformation efficiency induced by ovariectomy.

Objective: To observe the influence on curative effect of aescine in curing Lumbar intervertebral disc prolapse(LIDP) before and after operation. Methods: 184 cases of patients with LIDP were divided into two groups. 96 cases in curative group began to be used 10mg of aescin by adding to infusion of iv drip bid 3 days before the operation, and contie for 6-8 days it. 88 cases in control group were only operated.Results: Curative group was superior to control group in lysis of pain, postoperative La feeling and improvement of muscle strength. The excellent and better rates in two groups are 72.91%, 91.67% and 43.18%, 85.22%. The excellent rate of curative group is higher than that of control group( P 0.05). There is no serious bad reaction of drug in curative group.Conclusion: Aescin used before and after operation is good to recovery of nervous function after LIDP operation.

Objective:To explore the relationship between expressions of guococorticoid receptor(GR)? and ? mRNA in peripheral blood mononuclear cell(PBMC) of patients with polymyositis/dermatomyositis(PM/DM) and the glucocorticoid(GC) efficacy.Methods:Reverse transcription-polymerase chain reaction(RT-PCR) was used to semiquantite the expressions of GR? and ? mRNA in PBMC of 18 cases of PM/DM patients sensitive to GC,10 cases of PM/DM patients resistant to GC and 20 cases of health blood donors.The levels of cortisol in sera of PM/DM patients and of health donors were detected using radioimmunoassay.Results:There was no significant difference in the levels of seral cortisol among PM/DM patients sensitive to GC, resistant to GC and the health donors.The expressions of GR? mRNA in PBMC from PM/DM patients either sensitive to GC or resistant to GC were significantly lower those that of the normal control. Moreover,the expression of GR? mRNA in PBMC of PM/DM patients resistant to GC was significantly lower than that of patients sensitive to GC. While the expression of GR? mRNA in PBMC of PM/DM patients was significantly higher than that of the normal control,there was no significant difference of the expression of GR? mRNA between PM/DM patients sensitive and resistant to GC.Conclusion:The lower expression of GR? mRNA in PM/DM patients may be related to resistance to GC therapy,whereas there is no significant role of the expression level of GR? mRNA.

EGFR-TKI plays an important role in the treatment of non-small-cell lung cancer. However, some researchers find that there are still some patients with primary or acquired resistance to EGFR-TKI. The present known mechanisms of acquired drug resistance finally lead to the re-activation EGFR downstream signa-ling pathways. Liver X receptor agonist has inhibition function to several critical steps of EGFR downstream sig-naling pathways PI3K-Akt-NF-κB,which makes it possible to overcome the drug resistance.

Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) is one of the most important targeted drugs for lung cancer patients carrying EGFR sensitive mutations.However,almost all patients that are effective to this treatment will eventually develop secondary resistance to EGFR-TKI.The most accepted mechanisms of resistance mainly include T790M mutation,MET amplification,PIK3CA mutation,down-regulation of PTEN expression and activation of Fas-transcription factor-κB.Recent years,many new drugs are developed to overcome this resistance.Although most of drugs are in the stages of cell or animal experiment,some new drugs get positive clinical results.

0.05). Conclusion The g.168_185del polymorphism of the promoter in DJ-1 gene does not a significant risk factor for PD in this population.

Objective To investigate prevalence of associated diseases in patients with gout as well as their diagnoses and treatment. Methods Two hundreds out-patients diagnosed with gout from April to October 2008 were investigated at Peking University People's Hospital, and information collected included their general characteristics, associated diseases, diagnoses and treatment, as well as blood lipid profiles, serum creatinine, uric acid, results of routine urine tests and glomerular filtration rate estimated by MDRD formula in the past three months. Results Among patients with gout, prevalence of associated hypertension, obesity, renal calculi, coronary heart disease, cerebral infarction and diabetes were 54.5% (109/200), 23.2% (42/181), 20.0% (40/200), 12.0% (24/200), 8.0% (16/200) and 7.0% (14/200), respectively, and 53.7% (101/188) of them associated with hypertriglyceridemia, 63.7% (114/179) with impaired renal function and 15.1% (27/179) with chronic kidney disease. In acute attack of gout, 124 (62.0%) of them were treated with non-steroidal anti-inflammatory drug (NASID), 72 (36.0%) with colchicines, 12 (6.0%) with corticosteroid and 30 (15.0%) with urate-lowering drugs, respectively, and during its intermittent period, 69. 8% (81/116) of them received urate-lowering therapy with indications generally accepted internationally, but serum level of uric acid could be maintained below 0.06 g/L in only 8.6% (10/116) of them. And 73.8% (48/65) of the patients with no therapy indications also were treated with urate-lowering drugs. Conclusions The most commonly associated diseases in gout patients are hypertension, hyperlipidemia and obesity, followed by renal calculi, chronic kidney disease and coronary heart disease, and so on. At present, oral NSAID is the first choice of drugs for its acute attack. Indications for urate-lowering therapy in this hospital usually are not consistent with those by generally international acceptance, with lower therapeutic effectiveness achieved.

Objective To detect the expressions of vascular endothelial growth factor(VEGF) and Periostin in patients with diabetic retinopathy (DR),and to explore its chnical significance.Methods A total of 52 patients with DR (DR group),36 non-DR diabetic patients (non-DR group) and 30 healthy person (normal control group) were enrolled.The 52 cases of DR patients were divided into non-proliferative DR (PDR) group (non-PDR group,24 cases) and PDR group (28 cases).The expressions of serum VEGF and Periostin were detected with enzyme-linked immunosorbent assay analysis.Results The serum expressions of VEGF and Periostin were significantly higher in non-DR group and DR group than those in normal control group [(122.63 ±28.74),(163.58 ±42.37) mg/L vs.(91.53 ± 19.58) mg/L,(110.15 ±32.62),(146.51 ± 41.74) mg/L vs.(82.26 ± 21.17) mg/L,P ＜ 0.05 or ＜ 0.01].The serum expressions of VEGF and Periostin were significantly higher in DR group than those in non-DR group (P ＜0.05).The serum expressions of VEGF and Periostin were significantly higher in PDR group than those in non-PDR group [(174.15 ±47.31) mg/L vs.(147.66 ±38.25) mag/L,(160.31 ±46.43) mg/L vs.(132.14 ±35.62)mg/L,P ＜ 0.05].The serum expression of VEGF was positively related with Periostin (r =0.415,P ＜ 0.01).Conclusion The high-expressions of VEGF and Periostin are found in DR patients,and which maybe play a key role in the early diagnosis and assessment the progression of DR patients.

Objective· To identify the effect and potential mechanism of gambogic acid (GA) on natural killer/T-cell lymphoma (NK/TCL) cell lines.Methods · SNK-1,SNK-6 and SNT-8 were incubated with various concentrations of GA for 24 h,and cell viability was detected with CCK-8 assay.Cell apoptosis was examined by Annexin V-FITC/PI staining assay.Levels of proteins regulating cell apoptosis and phosphorylation levels of proteins in key signaling pathways were detected by Western blotting.Results · GA showed a potent effect on reduction of cell viability of NK/fCL cell lines in CCK-8 assay.GA increased the percentages of Annexin V positive cells and induced activation of caspase-3 and caspase-9,cleavage of PARP as well as the reduction of Bcl-xl.GA also inhibited the phosphorylation levels of STAT3 in SNK-1 and SNT-8,and ERK1/2 in SNK-1 and SNK-6 significantly.Conclusion· GA induces cell apoptosis in NK/TCL cell lines SNK-1,SNK-6 and SNT-8.Anti-apoptosis protein Bcl-xl and signaling pathway JAKs/STATs and MEK/MAPK might be involved in this process.
