CONCLUSION:Monitoring and prevention of ADR are useful methads to promote rational use of drug and safety of drug use.

Objective To explore the risk factors for asthma in children.Methods A 1:1 matched and hospital-based case-control study was conducted to analyses risk factors for asthma in 300 pairs of children by logistic regression analysis. Results The result of univariate Logistic regression analysis showed that there were 17 related factors for children asthma, including disease history of parents in respiratory system,family income,atopie character,history of acute respiratory infections, eating habit,the amount of sea foods intakes,foam plastics,family decoration,the way of exhaust fume in kitchen,the exhaust effectiveness,raising pet in house,family history of asthma,family history of allergic rhinitis,family history of food allergy,dust allergy of parents,systemic therapy after the first attack.With multivariate Logistic regression analysis,7 factors were entered the model,6 risk factors including father's history of respiratory diseases(OR 3.771,95%CI 1.533～9.278),low family income(OR 1.503, 95%CI 1.258～1.795),atopy(OR 3.788,95%CI 2.368～6.058),meat-eating habit(OR 2.042,95%CI 1.481～2.815),asthma history of family members(OR 1.710,95%CI 0.988～2.958),the family history of allergic rhinitis(OR 1.991,95%CI 1.234～3.211), and 1 protective factor of raising pet in house(OR 0.443,95%CI 0.265～0.739).The coefficients of these factors in multivariate logistic regression model were 1.327、0.407、1.322、0.714、0.536、0.689、and-0.814 respectively.Conclusion Children asthma was a multi-factorial complex disease,and the interaction of environmental and genetic risk factors played an important role in the onset of this disease.

OBJECTIVE: To observe the clinical effect of escin on patients with cutaneous pruritus caused by blood stasis and wind-dryness and to prove the theory that "wind should be treated by regulating blood disorder, and wind disappears after activating blood" in traditional Chinese medicine (TCM). METHODS: Fifty-one patients were randomly divided into escin-treated group (n=30) and loratadine-treated group (n=21). The patients in the escin-treated group were treated with escin for 4 weeks (300 mg, b.i.d.), and the patients in the loratadine-treated group were treated with loratadine (10 mg, q.d.). Symptom score reducing index (SSRI) was used to assess the pruritus degree, lesion range and lesion shape before the treatment, 2 weeks and 4 weeks after the treatment, respectively. RESULTS: Two weeks after the treatment, the effective rate of the escin-treated group was 63.3%, and the effective rate of the loratadine-treated group was 67.0%. Four weeks after the treatment, the effective rates were 86.7% and 80.0% in escin- and loratadine-treated groups respectively. There was no statistical difference in total scores of SSRI in two groups (P>0.05), and the scores of pruritus degree and lesion shape also had no statistical difference (P>0.05), while the score of lesion range of the escin-treated group was lower than that of the loratadine-treated group (P<0.05). CONCLUSION: Escin has satisfactory effect in treating pruritus caused by blood stasis and wind-dryness. The study confirms the TCM theory that "wind should be treated by regulating blood disorder, and wind disappears after activating blood".

Objective To analyze the monitoring results of human and animal plague in Zhangye city from 1982 to 2011,and further explore the prevention and control policies and measures to control the spread of the disease.Methods The trends of human and animal plague were studied by retrospective survey in Zhangye city.Information of animal and human plague epidemic and prevention and control measures were collcoted and assessed with epidemiology methods,and the density of rodents,the rodents infected with flea,flea index and other indicators were calculated.Results 1982-2011,there were 6 cases of human plague incidence of 6 cases,of which 2 cases cured,4 cases died,the mortality rate was 67％; detection of Yersinia pestis from the captured 5167 animals was 93 strains from 1982 to 2011,the detection rate was 1.80％; 29 840 various vector insects were collected from the body surface of the 5167 animals captured,21 206 hole dries,and three marmot dens.A total of 7050 groups of Marmota parasites and hole stem fleas were inspected,52 strains of Yersinia pestis were isolated,and the average detection rate was 0.74％; 3912 marmot serums were detected,178 were positive,and the positive rate was 4.55％.Conclusions The prevention and control of plague is still very grim in Zhangye city.It is recommended to take publicity,education and active surveillance measures in the future to deal with emergencies and other.

Objective To investigate the potential association between 163A/G and 950T/C polymorphisms of osteoprotegerin(OPG)gene and severe pre-eclampsia.Methods Eighty-five severe preeclamptic patients and 81 normal term pregnant women(as control group)were recruited from the Department of Obstetrics and Gynecology,West China Second University Hospital,Sichuan University during the period from July 2007 to March 2009,and they were all Han population living in Chengdu,China.Genotype and allele frequencies of 163A/G and 950T/C were determined by the PCR-restriction fragment length polymorphism(RFLP)assay.Clinical and biochemical parameters for different alleles between the patients and controls were compared for statistical significance respectively,such as blood pressure,serum creatinine and 24-hour urine protein.Results The observed and expected genotype counts were consistent with Hardy-Weinberg equilibrium.No significant differences were found in the genotype and allele frequencies of 163A/G and 950T/C polymorphisms between the two groups(P ＞ 0.05).However,in the preeclamptic group,serum creatinine was significantly higher in women with the AG + GG genotypes [(76 ±24)μmol/L]compared with AA genotype[(56 ± 18)μmol/L].Reversely,birth weight was lower in the AG + GG genotypes[(2040 ± 721)g]than those in the AA genotype[(2520 ± 810)g],and the P ＜0.05,respectively.In the severe pre-eclampsia,950T/C TT genotype carriers exhibited significantly higher systolic blood pressure[(153 ± 16)mm Hg(1 mm Hg =0.133 kPa)]and 24-hour urine protein [(4.0±2.5)g]compared with TT + TC carriers[(145 ±17)mm Hg,(2.9±1.8)g],respectively,furthermore the P ＜ 0.05.Conclusions In severe pre-eclampsia,carriers with G allele at position 163A/G has more genetic predisposition than A allele carriers,as well as 950T/C T allele carriers compared with C carriers.Taken together,this study suggested that OPG gene polymorphisms might be associated with some clinical parameters of severe pre-eclampsia.

Objective To study the relationship of serum visfatin level and coronary heart disease (CHD). Methods Eighty eight hospitalized patients were enrolled into the study and divided into CHD group(n = 62) and non-CHD control group(n = 26) according to the angiography results; the CHD group was further divided into single-, double-, multi-vessel affected groups. The serum level of visfatin was measured by ELISA,the lesion severity of coronary arteries was assessed by Gensini coronary scoring system, and the correlation between serum visfatin level and coronary lesion severity was evaluated statistically. Results The level of serum visfatin was significantly higher in CHD group than the control group([ 10. 77 ± 2. 63 ] μg/L vs. [ 7. 13 ± 2. 06 ]μg/L,P ＜ 0. 05). The visfatin level increased along with the the number of stenosis vessels(P ＜ 0. 05). The sermn visfatin levels of no stenosis, single-, double-, multi-vessel groups were(7. 13 ± 2. 06) μg/L,(9. 30±2. 19) μg/L,(10. 81 ± 2. 12) μg/L,(12. 79 ± 2. 20) μg/L respectively. A significant positive correlation was found between coronary lesion severity score and serum visfatin level(r = 0. 483, P ＜ 0. 01). Conclusion The visfatin may be directly related to the initiation and development of coronary diseases. The higher level of serum visfatin was, the more severe coronary artery disease would be.

OBJECTIVETo explore the effects of nano-hydroxyapatite/polyamide 66 (n-HA/PA66) cage on recovering and maintaining lumbar curvature, lumbar heights and fusion rate when used in the transforaminal lumbar interbody fusion.

METHODSFrom February to July 2012, 50 patients with degenerative lumbar disease(lumbar disc herniation in 32 cases and lumbar spondylolisthesis in 18 cases) were treated with transforaminal lumbar interbody fusion using the n-HA/PA66 cage, and their preoperative and postoperative clinical outcomes were analyzed. The patients were followed up for 2, 4, 6 and 8 months after operation, during which the CR and CT film of lumbar vertebra were checked to get relative height of vertebral space, Taillard index,index of lumbar spinal curvature,angle of segmental and full lumbar lordosis. The data were analyzed respectively with pair t-test, analysis of variance or LSD-t-test.

RESULTSAll the patients were followed up, and the duraion ranged from 8 to 13 months, with a mean of 11.32 months. There were significant differences in relative height of vertebral space, Taillard index, index of lumbar spinal curvature, angle of segmental and full lumbar lordosis after surgery, but there were no significant differences in different periods after operation. The fusion time of lumbar ranged from 4 to 8 months.

CONCLUSIONThe n-HA/PA66 cage can recover and maintain lumbar normal stability with higher rate of fusion and less complications.
