Objective To investigate the correlation between interleukin-1β(IL-1β),interleukin-1 receptor antagonist(IL-1 ra)and the obesity of polycystic ovary syndrome(PCOS).Methods(1)From Oct.2006 to Jan.2007,118 PCOS patients were enrolled in this study in Peking University Third Hospital,which were divided into 56 patients in obese PCOS group and 62 patients in non-obese PCOS group according to the WHO International Obesity Task Force Asia-Pacific criteria[body mass index(BMI)25 kg/m2].The polymorphism of IL-1β gene promoter region,exon-5 and intron 2 of IL-1 ra gene were detected by PCR.(2)Twenty-nine obese PCOS patients and 31 non-obese PCOS patients were selected randomizedly serum levels of IL-1β,IL-1 ra were measured by ELISA,in the mean time,serum levels of fasting glucose,fasting insulin and the total white blood cell,hypersensitive C-reactive protein levels were measured.Results(1)Genetic test:the frequency of TT genotype and T allele of IL-1β promoter region(-511)in obese PCOS patients were significantly higher than those in non-obese patients(44.6％ vs.11.3％,63.4％ vs.39.5％,all P ＜0.05).The frequency of IL-1 ra Ⅰ / Ⅴ genotype and Ⅴ allele of IL-1 ra gene were 19.6％ and 9.8％ in obese PCOS patients,which were significantly higher than those in non-obese group(3.2％ and 1.6％,P ＜0.05).(2)Serological test:serum level of IL-1β and IL-1ra of(149 ±36)and(284 ±97)ng/L in obese PCOS group which were significantly higher than those in non-obese PCOS group[(96 ± 42)and(208 ± 84)ng/L,P ＜ 0.05].Fasting blood glucose,fasting insulin and hypersensitive C-reactive protein and white blood cell count were(5.1 ± 0.7)mmol/L,(17 ± 9)mU/L,(1.5 ± 0.6)mg/L and(7.0 ± 2.3)× 109/L in obese PCOS group,which were significantly higher than in non-obese PCOS group[(4.9 ±0.5)mmol/L,(11 ±8)mU/L,(0.9 ±0.4)mg/L and(5.9 ±1.3)× 109/L,P＜0.05].(3)The correlation between interleukin and BMI: serum levels of IL-1β(r =0.673)and IL-1 ra(r =0.557)were positively correlated with BMI in PCOS patients(P ＜ 0.05).Conclusions Inflammatory factors IL-1β and IL-1ra had correlation with obesity of PCOS patients,PCOS patients who carried T allele of IL-1β gene promoter region(-511)and Ⅴ allele of IL-1ra gene were high risk of obesity.

Objective To explore the expression of FOXM1 in non-small cell lung cancer(NSCLC) and the relationship between FOXM1 expression and the clinical pathological factors,clinical response to target-therapy in NSCLC remained unknown.Methods A total of 80 NSCLC patients were recruited into this study,FOXM1 expression was assessed by immunohistochemistry and analyzed with the clinical pathological factors and clinical response to target-therapy.Results The positive rate of FOXM1 expression was 41.25%.The positive expression of FOXM1 had no significant difference in patients with different age,gender,cancer staging,smoking history(P>0.05),but had significant difference in patients with different degree of differentiation,lymph node metastasis(P<0.05).Survival time in patients with positive FOXM1 expression was significant shorter than that with negative FOXM1 expression(P<0.05).Conclusion The expression of FOXM1 closely correlated with patients histological differentiation,lymph node metastasis,progress-free survival time in patients with positive FOXM1 expression was significantly shorter than those with negative FOXM1 expression.

ObjectiveTo explore the association of smoking to the Aspirin and Clopidogrel antiplatelet in patients with stable angina after percutaneous coronary intervention (PCI). Methods241 smoking patients and 252 non-smoking patients underwent PCI for stable coronary artery disease, all patients had taken aspirin 100 mg/d for 7 d or more. The arachidonic acid (AA)- and adenosine diphosphate (ADP)-induced platelet aggregation were tested as they got in hospital. Then, they accepted Clopidogrel 300 mg as loading dose, continued with 75 mg/d for 3 d. The ADP-induced platelet aggregation were re-tested. ResultsThe incidence of aspirin resistance (AR) and aspirin semiresponder (ASR) was 19.1% in all the cases, and was 25.5% in smoking group, 14.3% in non-smoking group (P=0.027). Age (OR=3.79，95%CI: 1.77～8.12) and smoking (OR=1.98，95%CI: 1.18～4.43) were the independent risk factors of AR and ASR. The incidence of Clopidogrel resistance was 19.5% in all the cases, and was 13.2% in smoking group, 24.3% in non-smoking group (P=0.03). Smoking (OR=0.22，95%CI: 0.09～0.54) may reduce the risk of Clopidogrel resistance. ConclusionSmoking increased the risk of AR and ASR, but reduced the risk of Clopidogrel resistance.

The on-line monitor for the changes in the content of baicalin in Scutellariae Radix formula particles during the extraction process was conducted by using near infrared spectroscopy (NIR). High performance liquid chromatography (HPLC) was used as a reference method. Kennard-Stone (KS) was used to divide sample sets, so as to compare different pretreatment methods. The synergy interval partial least squares (SiPLS) was used to screen out modeling wave band to establish partial least-squares models. The relative error method was applied to predict forecast set samples of Scutellariae Radix in three extraction phases. The results showed that the model established by Savitzky-Golay smoothing with 11 points (SG11 points) was the best, with the root mean square with cross validation (RMSECV), root mean square error of correction (RMSEC) and root mean square error of prediction (RMSEP) of baicalin of 0.092 7, 0.134 4 and 0.114 8, respectively, the determination coefficient R2 of greater than 0.99, and the relative error of baicalin content of less than 5%. This indicates that the on-line near infrared reflectance spectroscopy could be applied in on-line monitor and quality control of the extraction process of Scutellariae Radix formula particles.

Microbes that produce Docosahexaenoic Acid were isolated from seawater. 160 strains capable of producing lipids were screened out using Sudan Black B dying method from 280 seawater samples. From 60 strains of microorganisms producing bigger lipid particles, 7 strains of them capable of producing lipids more than 8% were obtained with Soxhlet abstracting method in the first screening. In the secondary screening from 10 strains with high lipids yield, strain 7-3 capable of producing 15.9% lipids was obtained, in which the content of DHA(Docosahexaenoic Acid)is 45.2%. Strain 7-3 was identified as Brettanomyces based on its morphological properties, cultural characteristics, physiological and biochemical properties.

Objective To discuss the application and effect of predictive care in stage divided treatment and salvage of children's persistent status of epilepsy (SE).Methods Sixty-four children with SE were admitted to the First Peoples Hospital of Wenling in Zhejiang Province from December 2014 to December 2016 as the research objects, a controlled study was adopted, in which the stage divided therapeutic method was compared with the conventional method for treatment of SE, and the children were divided into an observation group and a control group, 32 cases in each group. Foresight treatment method was used in the observation group: the first stage of treatment (early treatment or pre-hospital treatment) was intravenous injection of the first-line drugs (benzodiazepines); the second stage of treatment (progressive stage treatment or initial treatment) mainly used epileptic drugs to prevent recurrence; the third stage treatment (referred to after the first-line drug in combination with one second line antiepileptic drug treatment, the disease was still unable to be controlled) adopted the mild hypothermia therapy to reduce the SE attack amplitude and decrease recurrence; in terms of aspects of predictive nursing measures, the respiratory tract nursing, basic nursing, the prediction of complications and their nursing, etc. were implemented. The routine nursing without care about the stages was carried out in the control group. The SE control time, skin lesions, false aspiration, lung infection, tongue bite, cerebral edema, etc. the incidenceof complications were observed in two groups of children.Results The SE control time was significantly shorter in observation group than that in the control group (minutes: 18.13±3.15 vs. 25.19±2.69,P < 0.05), and the incidence of complications was obviously lower in observation group than that in the control group [6.25% (2/32) vs. 28.13% (9/32),P < 0.05]. Conclusion Using different therapy at different stages of children SE combined with predictive care can effectively shorten the SE control time, decrease the incidence of complications and elevate the therapeutic and nursing effects.
