Objective To study the relationship between bronchial asthma and smoking status in Chinese people.Methods Asthma epidemiological survey and stratified-cluster-random method survey were performed in residents over 14 years in 8 provinces (cities) of China from February 2010 to August 2012.Asthma was diagnosed based upon case history,clinical signs and lung function test.Smoking status was investigated by questionnaire.Results Sampling population was 180 099 and 164 215 were valid.A total of 2 034 subjects were diagnosed as asthma including 79 692 men and 84 523 women.The overall prevalence rate of asthma was 1.24％ (2 034/164 215).Smokers were 23.8％ (39 137/164 215) in the whole population.Smokers were 34.5％ (702/2 034) in asthmatic patients,compared with 23.7％ (38 435/ 162 181) in no-asthmatic population.The incidence of asthma was 1.79％ and 1.06％ in smokers and nonsmokers respectively (P ＜0.001),suggesting that OR of smoking was 1.70 (95％ CI 1.55-1.86,P ＜ 0.001).According to asthma control test (ACT) score,the level of asthma control in non smoking group was higher than that in smoking group(43.2％ vs 35.3％).The times of hospitalization due to acute exacerbations (0.51 vs 0.41 events/person/year),total hospitalization rate (27.35 ％ vs 20.12％),annual emergency room visits (0.80 vs 0.60 events/person/year) and emergency room visit rate (31.77％ vs 24.47％) were all much higher in smoking asthmatic patients than those in non smoking asthmatic patients,indicating that the level of asthma control in smoking patients was significantly worse than in non smoking patients.Conclusions The smoking rate in Chinese people over 14 years is still high.The prevalence rate of asthma in smokers is significantly higher than that of non-smokers.The level of asthma control in smokers is significantly worse than that in non smokers.

Objective To investigate the clinical effects differences of three-port and single-port invasively combination laparoscopic cholecystectomy and appendectomy in the treatment of acute appendicitis complicated with gallbladder stone. Methods 110 patients with acute appendicitis complicated with gallbladder stones from August 2012 to August 2015 were randomly divided into control group (55 patients) with three-port laparoscopic operation and observation group (55 patients) with single-port laparoscopic operation;and the clinical indexes for operation related, operation overall satisfaction score of Brown, the VAS score of depression and anxiety before and after operation and postoperative complications of both groups were compared. Results The incision length of observation group was significantly shorter than control group (P< 0.05). The operative time of observation group was significantly longer than control group (P < 0.05). The operation overall satisfaction of Brown of observation group was significantly higher than control group (P < 0.05). The VAS score of depression and anxiety after operation of observation group was significantly better than control group and before operation (P<0.05). There was no signiifcant difference in the incidence of postoperative complications between 2 groups (P < 0.05). Conclusion Compared with three-port laparoscopic operation, single-port invasively combination laparoscopic cholecystectomy and appendectomy in the treatment of acute appendicitis complicated with gallbladder stone can efifciently decrease the incision length, improve the aesthetic degree and postoperative negative emotions and not lead to increased risk of postoperative complications.

Objective To investigate the effect of simvastatin and aspirin on atherosclerosis and its effect on non endothelium dependent diastolic function(NMD)and blood lipid in patients.Methods Retrospective analyzed a total of 95 the clinical data of patients with atherosclerosis treated in Tianjin Baodi Hospital from August 2014 to May 2016.The patients were divided into simvastatin group and combined treatment group according to their treatment methods,simvastatin group was given simvastatin,combined treatment group was given aspirin on the basis of simvastatin.After four weeks treatment,the difference of plaque quantity,NMD and blood lipid between the two groups were observed.Results After treatment,the size and number of plaques in the combined treatment group were smaller than those in the simvastatin group,the difference was statistically significant(P<0.05),the NMD level in the combined treatment group was significantly higher than that in the simvastatin group,the difference was statistically significant(P<0.05),the levels of IL-18,IL-6 and hs-CRP in the combined treatment group were lower than those in the simvastatin group,the difference was statistically significant(P<0.05),the levels of LDL-C,TG and TC in the combined treatment group were lower than those in the simvastatin group,HDL-C levels were higher than simvastatin group,the difference was statistically significant(P<0.05).Conclusion Simvastatin combined with aspirin can significantly improve the endothelium dependent diastolic function and lipid level in patients with atherosclerosis,and has good therapeutic effect.

Objective To investigate the diagnostic value of PIgP/SC in diagnosis of primary hepatic cancer.Methods 58 patients with primary hepatic cancer,60 patients with liver cirrhosis and 60 healthy volunteers were studied.4 ml fasting venous blood was collected from all subjects.Serum level of AFP was detected with electrochemical chemiluminescence immunoassay system and plasma PIgR/SC level was detected by ELISA method.The level of PIgR/SC and AFP was detected at one week after surgical resection in patients with hepatic cancer.Results The levels of AFP and PIgR/SC in the three groups were significantly different (P＜0.01),and PIgR/SC was higher than that in patients with cirrhosis and volunteers (P＜0.01).There was no significant difference between patients with liver cirrhosis and liver cirrhosis(P＞0.05).AFP was higher in patients with HCC than patients with cirrhosis and volunteers.AFP was higher in patients with cirrhosis than volunteers,and the difference was statistically significant(P＜0.01).Sensitivity of PIgR/SC and AFP was 89.3％ and 54.8％,specificity was 84.6％ and 91％,Youden index was 0.751 and 0.458,AUC was 0.920 and 0.761,respectively.There was significant difference in AUC (Z=3.251,P＜0.05) of the two detection indexes for detection of primary hepatic cancer.Conclusion The value of PIgR/SC in diagnosis of primary liver cancer may by higher than that of AFP.

Objective To evaluate the relationship between cardiomyopathy-associated 5 (CMYAS) gene rs10043986 polymorphism and schizophrenia in Uygur Chinese population.Methods The SNP rs10043986 in CMYA5 gene was genotyped in 325 patients with schizophrenia and 183 normal controls using TaqMan technology.The symptoms of schizophrenia were assessed by positive and negative syndrome scale (PANSS).The association of the loci with schizophrenia,age of onset,clinical symptom was analyzed.Results The allelic and genotypic distributions in rs10043986 between patients with schizophrenia (C,T allele:91.5％,8.5％ ; C/C,C/T,T/T genotypes:83.4％,16.3％,0.3％) and normal controls (C,T allele:96.4％,3.6％ ; C/C,C/T,T/T genotypes:92.9％,7.1％,0) had statistically significance after analysis (x2 =9.038,P=0.003 ; x2 =9.417,P=0.009).Via analysis of stratification by gender and age at onset.The results showed that both allele (x2=11.812,P=0.001) and genotype (x2=12.769,P=0.001) frequency in rs10043986 with patients were significantly different in females,but neither in males (all P＞0.05).Allelic or genotypic distributions between adult cases and controls had statistically significance (x2=8.219,P=0.004; x2=8.379,P=0.015),but there were not significant differences between adolescent cases and controls (all P＞ 0.05).Furthermore,we also notice that the PANSS scores of patients between Genotype C/C and C/T had no statistically significance (allP＞0.05).Conclusion The results reveal that T allele at CMYA5 rs10043986 may be confer risk for susceptibility of female and adult schizophrenia in Uygur Chinese population,and that rs 10043986 polymorphism may not significantly associate with symptoms severity of schizophrenia.
