[Summary] Various complications of type 2 diabetes mellitus (T2DM) are more harmful than T2DM itself.Cardiovascular diseases (CVD) are the major causes of diabetes-associated disability and mortality.Most studies have shown a close relationship between the lifestyles of T2DM patients and the development of CVD.Keeping a healthy lifestyle is essential in preventing and treating CVD for patients with T2DM.This article was tried to elucidate the roles of different components of diet,exercises,and sedentary behavior on diabetic CVD.

Objective This study aimed to assess the effects of active and passive smoking on chronic kidney disease (CKD) in patients with type 2 diabetes mellitus (T2DM).Methods Seven hundred and five patients with T2DM were recruited in the study and were divided into three groups based on smoking status as active smokers,passive smokers and non-smokers.Twenty-four hour urinary albumin excretion (24hUAE) was measured,and estimate glomerular filtration rate (eGFR) was calculated with age and blood creatinine levels.Results (1) The proportion of CKD in T2DM in the present study was 31.63％ (223/705) with 28.6％ (22/77),30.0％ (15/50) and 29.6％ (73/247) for non-smokers,passive smokers and active smokers in men,and 29.9％ (40/134),35.9％ (66/184) and 7/13 for non-smokers,passive smokers and active smokers in women,respectively.In comparison with non-smokers,a higher risk of CKD was found in both passive and active smokers (OR =1.07 and OR =1.05 in men ; OR =1.31 and OR =2.74 in women,respectively).(2) Compared with non-smokers,passive smokers had a significant higher risk for albuminuria in women (OR =2.02,P =0.016).(3) After adjusting for gender,age,duration of T2DM,BMI,systolic blood pressure,glycosylated hemoglobin A1C and lipids,there was a significant decrease in eGFR between active and never smokers (P =0.018)or passive smokers (P =0.000) in women.No differences could be found in eGFR between each smoking statues in men.Conclusions Smoking exposure alone confers a high risk for CKD in patients with T2DM.Our results highlight an importance in implementation of a smoke-free environment for patients with T2DM.

OBJECTIVETo observe the effect of Jianpi Bushen Qingchang Huashi Recipe (JBQHR) on proliferation and migration of bone marrow mesenchymal stem cells (BMSCs).

METHODSBMSCs were isolated and cultured in vitro with adherence screening method to prepare cell suspension. No drug intervention was given to BMSCs in the vehicle control group. JBQHR at 0.39, 0.78, 1.56 µg/mL was added in BMSCs of low, mid, and high dose JBQHR groups for co-incubation. Its effect on the proliferation of BMSCs was detected by CCK-8. BMSCs migration and chemotactic ability was detected using Transwell method. Each dose JBQHR combined ERK kinase inhibitor U0126 was set up as control. The phosphorylation of extracellular regulated protein kinase (ERK) and CAMP responsive element-binding protein (CREB) were detected by Western blot.

RESULTSCompared with the vehicle control group, the proliferation of BMSCs and BMSCs migration number could be promoted in the 3 JBQHR groups (P < 0.05). Besides, the proliferation of BMSCs was better in mid and high dose JBQHR groups than in the low dose JBQHR group (P < 0.05). Compared with the vehicle control group, the phosphorylation of ERK and CREB could be elevated in the 3 JBQHR groups (P < 0.05), and could be inhibited by U0126 (P < 0.01). Compared with the low dose JBQHR group, the phosphorylation of ERK increased in mid and high dose JBQHR groups with statistical difference (P < 0.05).

CONCLUSIONJBQHR could promote the proliferation and migration of BMSCs, and its mechanism might be related to ERK/CREB signaling pathway

The purpose of the secondary exploitation of Chinese medicine is to improve the quality of Chinese medicine products, enhance core competitiveness, for better use in clinical practice, and more effectively solve the patient suffering. Herbs, extraction, separation, refreshing, preparation and quality control are all involved in the industry promotion of Chinese medicine secondary exploitation of industrial production. The Chinese medicine quality improvement and industry promotion could be realized with the whole process of process optimization, quality control, overall processes improvement. Based on the "component structure theory", "multi-dimensional structure & process dynamic quality control system" and systematic and holistic character of Chinese medicine, impacts of whole process were discussed. Technology systems of Chinese medicine industry promotion was built to provide theoretical basis for improving the quality and efficacy of the secondary development of traditional Chinese medicine products.

Objective To evaluate the diagnostic value of the metabolic parameters for differentiating focal autoimmune pancreatitis (F-AIP) and pancreatic cancer (PC) by dual time 18F-FDG PET/CT scan.Methods Ten F-AIP patients and 20 PC patients in Changhai Hospital from May 2011 to November 2014 were enrolled in this study.All the AIP patients were histological confirmed or diagnosed by clinical follow up.The PC patients were histological confirmed and gender-and age-matched with F-AIP patients.50％ SUVmax was set as the threshold to fine-tune the boundary of interest.The extracted parameters included SUV SUV metabolic tumor volume (MTV),total lesion glycolysis (TLG),target-to-background ratio (TBR) and the retention indexes(RI) of all the parameters above.The PET/CT imaging features were also observed.Results The high metabolic lesions were observed in both F-AIP patients and PC patients.There were 6 F-AIP patients whose lesion was located in pancreas head,4 F-AIP patients whose lesion was located in pancreas body and tail.There were 12 PC patients whose lesion was located in pancreas head,8 PC patients whose lesion was located in pancreas body and tail.In F-AIP patients,2 cases had dilated pancreatic duct,6 had dilated biliary duct,8 had increased metabolism in mediastinal lymph node and 2 had abdominal lymphadenopathy,which were 8,5,5 and 14 cases in PC patients.The positive rate of mdeiastinal lymphadenopathy in F-AIP patients was statistically higher than that in PC patients,while the positivity rate of abdominal lymphadenopathy in AIP patients was lower than that in PC patients.The difference was statistically significant (both P ＜ 0.05).There were no statistical differences on the positivity rate of the dilated pancreatic duct,intra-and extra-hepatic bile duct between two groups.SUVmax,SUVmean and MTV in F-AIP were 5.37 ± 0.88,3.48 ± 0.66,21.79 ±15.60 in early stage and 6.45 ±1.51,4.23 ± 1.10,19.36 ± 14.63 in delayed stage,and those in PC were 8.31 ±3.08,5.41±1.95,9.26±8.35 in early stage,and 9.75±3.86,6.36±2.56,9.09±10.71 in delayed stage.SUVmax and SUVmean in F-AIP were lower than those in PC,whereas MTV were larger in F-AIP than that in PC.ROC curves for SUVmax,SUVmean and MTV were made.The AUC of SUV was the highest at 0.85,the cut-off value was 4.45,the corresponding sensitivity was 65％ and the specificity was 90％.TLG,TBR and RI of all the parameters were not statistically different in F-AIP and PC.Conclusions The 18F-FDG PET/CT metabolic parameters,such as SUVmax,SUVmean,MTV,could be of special diagnostic significance in discriminating F-AIP from PC.
