Leptin,the product of the obese gene,is a 16kDa secreted protein produced by white adipocytes.Because of its dual nature as a hormone and cytokine,leptin plays a role in regulating energy metabolism,inflam-marion,immune response,neuroendocrine and angiogenesis,and so on.The review focuses on the research and controversy of leptin's effect in osteoarthritis.

Objective To investigate the effects of FKBP12.6 gene transfection on the contractility of ventricular myocytes of rats with heart failure.Methods Rat model of heart failure was established by a surgical operation of abdominal aortic stenosis.The enzymatic hydrolysis was employed to isolate the rats' ventricular myocytes.Mediated by adenovirus the FKBP12.6 gene was transfected into ventricular myocytes.Ad-GFP infected cardiac myocytes from heart failure rats and normal rats were used as control.Western blotting and reverse transcriptase-polymerase chain reaction(RT-PCR) were used to detect the specific overexpression of FKBP12.6.Transfected ventricular myocytes were loaded with the membrane-permeant Ca2+ dye X-rhod-1-AM.Under the condition of field stimulation,the laser confocal microscope in line-scan and plane-scan mode was used to detect the Ca2+ transients and myocytes contraction.Results The mRNA and protein levels of FKBP12.6 in the myocytes of rats with heart failure were significantly lower than that in normal myocytes(0.47?0.08 vs 0.96?0.12,0.25?0.04 vs 0.48?0.07,P

HPLC fingerprint of Congrong Zonggan capsule was established in order to provide basis for quality evaluation. With acteoside as the reference, HPLC was adopted for fingerprint analysis on Congrong Zonggan capsule. The chromatographic conditions wereas follows. Waters C18 column (4.6 mm x 150 mm, 5 μm) was used, with methylalcohol-0.1% formic acid as the mobile phase for gradient elution at the flow rate of 1.0 mL x min(-1). The detection wavelength was 330 nm, and the column temperature was 30 °C. This method was highly accurate and reproducible. All of the 13 components in tested samples reached the baseline resolved peak, and 15 batches of finished products showed the similarity of above 0.95. The method was accurate and feasible and could be used as a simple and effective method to evaluate the quality of the traditional Chinese medicines.

Objective · To compare the prevalence of tobacco advertisement before and after implementation of the new edition of Advertising Law of the People's Republic of China and evaluate the effects of implementation of the new Advertising Law. Methods · Tobacco sales places, public places, and streets in Shanghai were randomly selected to observe tobacco advertisement and complete the survey. The survey was carried out in 10 districts of Shanghai in June 2015 with 10 tobacco sales places selected in each district, and in 4 districts of Shanghai in June 2016 with 25 tobacco sales places selected in each district. Sales places included convenient stores, tobacco stores, supermarkets, and kiosks. In addition, public transport waiting points, public transport vehicles, hospitals, shopping centers, restaurants, bars, and Internet cafes were selected into survey in 2016. Results · In 2016, the proportion of tobacco sales places having tobacco advertisement was lower than that in 2015, but the proportion of tobacco promotion behaviors was higher. In 2016, 128 public places and streets were investigated and only 1 had outdoor tobacco advertisement. Conclusion · The new edition of Advertising Law has significant effect on controlling tobacco advertisement, but tobacco sales places still have tobacco advertisement with various disguised promotion forms. Tobacco sales places have diversified business styles and minors often enter these places. It is recommended that a clear definition of disguised forms of tobacco advertisement should be made, tobacco advertisement at tobacco sales places needs to be supervised, the release of tobacco advertisement should be strictly reviewed, and existing tobacco advertisement should be severely punished, so as to prevent minors from exposing to tobacco advertisement and information luring smoking.

AIM:To study the effects of FK506 binding protein 12.6(FKBP12.6) overexpression on the performance of sarcoplasmic reticulum(SR) in ventricular myocytes of rats with heart failure.METHODS:The adenovirus(Ad)-mediated gene transfer was used to overexpress FKBP12.6 in ventricular myocytes of rats with heart failure.Western blotting and reverse transcriptase-polymerase chain reaction(RT-PCR) analysis were used to reveale specific overexpression of FKBP12.6.X-rhod-1-AM was used as the Ca2+ indicator,and cells were viewed under a confocal microscope.RESULTS:Adenovirus mediated overexpression of FKBP12.6 resulted in a 5-fold increase in relative FKBP12.6 mRNA levels and a 4-fold increase in relative FKBP12.6 protein levels at 48 h after transfection compared with control.The amplitude of the fluorescence [Ca2+]i transient was significantly increased in Ad-FKBP12.6-GFP cardiomyocytes compared with Ad-GFP myocytes(peak F/F0,3.16?0.42 vs 1.43?0.38,P
