ABSTRACT

Objective:To evaluate the association between smoking and the risk of type 2 diabetes (T2DM) incidence among Asian adults based on the prospective studies.Methods:Prospective studies conducted on Asian adults through May, 2019 were retrieved from the following databases: SinoMed, CNKI, VIP, WanFang, PubMed, Web of Science, Embase, and Cochrane Library. Then data were extracted on smoking status, smoking quantity, the number of newly-onset T2DM cases, and effect sizes.Results:A total of 31 studies were included. There were 2 159 787 investigators, 599 340 (27.75%) smokers, and 124 883 (5.78%) T2DM cases identified during the mean follow-up period of 8.3 years. Compared with non-smokers, the combined relativerisk ( RR) and 95% confidence interval ( CI) of current smokers and quitting smokers were 1.52 (1.34- -1.72) ( P<0.001) and 1.22 (1.09- -1.37) ( P=0.047), respectively. The RR and 95% CI of light smokers (<20/day), moderate smokers (20- -29/day), and heavy smokers (≥30/day) were 1.31(1.21- -1.53) ( P=0.001),1.42(1.14- -1.76)( P=0.212), and 2.17(1.50- -3.16) ( P=0.198), respectively. In males and females, the RR and 95% CI were 1.15 (1.08- -1.21) ( P<0.001) and 1.20 (1.11- -1.30) ( P=0.038), respectively. In addition, compared with non-smokers, the RR and 95% CI of current smokers were 1.57 (1.22- -2.03) ( P<0.001) and 1.47 (1.30- -1.66) ( P=0.063) during the follow-up periods of less than and more than 8.0 years, respectively, while the RR and 95% CI of quitters were 1.23 (1.06- -1.43) ( P=0.091)and 1.20 (1.07- -1.34) ( P=0.041), respectively. Conclusions:Prospective studies based on Asian adults have shown that smoking significantly increases the risk of diabetes incidence. That is, as cigarette consumption increases, the risk of diabetes increases accordingly. Moreover, compared to males, the risk for female smokers is greater. In addition, longer durations of smoking cessation are associated with a lower risk of T2DM.

ABSTRACT

To enhance the quality control of tebipenem pivoxil and establish its quality criteria,the synthetic route of tebipenem pivoxil was analyzed and five related substances (P1,P2,P6,P8 and P9)were synthesized and characterized by 1H NMR and MS.The purities of the related substances were over 95% via HPLC detec-tion.The target compounds can be used as the reference of the related substances in the quality control of tebi-penem pivoxil.The starting materials were cheap and easy to obtain;the reaction conditions were mild.

ABSTRACT

Objective To investigate the risks of self-rated health in the ≥55-year elderly in Beijing and the occurrence of stroke.Methods The subjects (n=2 101;aged ≥55) from Beijing longitudinal study of aging (BLSA) were collected by Xuanwu Hospital,Capital Medical University from January 1992 to December 2016.One hundred and twenty-one subjects with stroke at baseline and 92 with incomplete information were excluded,and finally,1 888 elderly patients without cerebrovascular disease at baseline were included in the analysis.Based on the actual situation,the self-rated health was to identify an item that matched their current state from good,general to poor.The deadline for the survey was December 31,2012.The competitive risk model was used to assess the health self-rated status and the risk of stroke.Non-stroke deaths,including cancer and car accidents were treated as competitive events.Results Of the 1 888 subjects enrolled,946 (50.1%) self-rated health were good,616 (32.6%) were general,and 326 (17.3%) were poor;438 (23.2%) had stroke,751 (37.8%) had non-stroke death,and 699 (37.0%) were right censored data.Using the competing risk model and adjusting the age,sex,living area,marital status,education level,smoking,alcohol consumption,physical exercise,hypertension,diabetes mellitus,coronary heart disease,and body mass index,the occurrence of stroke in patients with poor self-rated health was 1.44 times (95%CI 1.11-1.87,P<0.01) as good as those who were good.Conclusion In the self-rated health of the elderly ≥55 years old in Beijing,the people with poor self-rated health increased the occurrence of stroke after considering the competitive risks.
