Objective To investigate relationship between insulin sensitivity and beta-cell function with body mass index (BMI) and age in patients with newly diagnosed type 2 diabetes mellitus (T2DM).Methods Totally, 304 patients with T2DM newly-diagnosed at admission to the first hospital affiliated to Nanjing Medical University, Jiangsu province, during 2006 to 2007 were recruited in the study. The patients were divided into three groups based on WHO criteria of obesity in Asia Pacific Region in 2003, 68 cases with normal weight ( 18. 5≤ BMI < 23.0), 69 in overweight (23.0 ≤ BMI < 25.0), and 167 in obesity (BMI≥25.0). Fasting serum glucose, glycesylated hemoglobin Alc (HbAlc) and lipids were measured for all the subjects, as well as oral glucose tolerance test (OGTr), C-peptide releasing tests and determination of serum insulin performed. Homeostasis model assessment of insulin resistance index (HOMA-IR), insulinogenic index (AI30/AG30) and modified beta-cell function index (MBCI) werecalculated to evaluate their insulin sensitivity and beta-cell function of the islets. All these parameters werecompared between the three groups and subgroups. Results HOMA-IR and MBCI were significantly higherin T2DM patients with obesity than those in the groups with normal weight and over-weight ( P < 0. 05 ).AI30/AG30 in obesity group was significantly higher than that in the group with normal weight (P <0. 05).Multiple linear regression analysis showed that BMI independently correlated with HOMA-IR ( P < O. 05 ).Sub-group analysis showed that △I30/△G30 and MBCI were significantly higher in those aged 60 years and over with obesity than those in the groups aged less than 60 years ( P < 0. 05 ). Conclusions Non-obese patients with newly diagnosed T2DM have more severe impaired insulin secretion than that in obese ones,and their insulin resistance increases with BMI. Age has no significant correlation with pancreatic beta-cell function or insulin sensitivity.

AIM: To investigate the effect and the mechanism of apolipoprotein (a) [apo (a) ] on proliferation of vascular smooth muscle cells ( VSMCs). METHODS: All VSMCs used in experiments were serial subcultured from primary cells and were identified by immunohistochemistry staining of a - actin. Cell growth assay was observed as cell counting and MTT assay. Western blotting was also employed to detect the related mechanism. RESULTS: All cells used in experiments were confirmed as VSMCs. Although apo (a) enhanced VSMCs proliferation, this effect was attenuated by anti -integrin α_vβ_3, LM609.Use these reagents alone had no effect on VSMCs growth. The results of Western blotting demonstrated that focal adhesion kinase (FAK) was activated by apo (a) and the expression of total or phosphorylated transforming growth factor β_1 (TGF -β_1) was also decreased. However, these effects described above were all blocked by LM609.CONCLUSION: Apolipoprotein (a) enhances VSMCs proliferation and this effect is mediated by integrin α_vβ_3, which activates FAK and attenuates TGF - β_1 and phospho -TGF - β_1 expression.

Chinese Traditional and Herbal Drugs 2017;48(20):4361-4366
The hospital is one of the main subjects for application of Chinese herbal pieces (CHP) which is the prescription drug for Chinese medicine clinical prevention and treatment of disease. The quality of CHP in hospital has a direct impact on clinical effect and is related to the health of the patients. But presently the market of CHP is chaotic with the prominent issue. The cultivation, the production and processing, the storage management and operation of CHP are not standardized. Simultaneously, the supply method of CHP is cut off from the right of the hospital to know the source and production process of CHP. The hospital is restricted to the supply enterprises of CHP. This situation makes a great obstacle to the quality control of CHP in hospital. The quality control system of CHP in hospital is composed of the source and the quality management of CHP. The quality control system of CHP includes the measures such as the purchasing management, acceptance of storage, storage and maintenance, and personnel capacity improvement. The prescription-based processing of Chinese materia medica should play an important role in this system. The whole process traceability system and the guarantee function of the market supervision system of Chinese medicinal materials should also be taken effect. In this way, the dominant position of hospital in the quality control system of CHP is strengthened.

BackgroundRetinal pigment epithelial(RPE) cells can secrete platelet-derived growth factor (PDGF) and PDGF receptor(PDGFR).Studies have shown that PDGF plays a key role in the formation of proliferative vitreous retinopathy(PVR). ObjectiveThis study was to investigate the proliferation and apoptosis changes of RPE after blockage of the PDGFR-α expression by antisense oligonucleotide ( ASODN ) in vitro. Methods Human RPE cells strain was cultured in low glucose DMEM with 10% fetal bovine serum.Logarithmic phase cells were collected and incubated in 96-well plate at the density of 5 × 105 cells/hole.PDGFR-α ASODN was transfected into RPE cells at different concentrations for 48 hours.The cells of the blank control group were regularly cultured without any transfection.The changes of PDGFR-α expression were detected by reverse transcription-polymerase chain reaction(RT-PCR),and the proliferation of RPE was detected by MTT as the A490 value.Hoechst 33258 fluorescence staining was used to determine the apoptosis of RPE.Flow cytometry method (FCM) was applied to detect the change of cell cycle and apoptosis rate of RPE cells. ResultsThe A490 values of RPE cells were 1.45±0.12,1.07±0.06,0.65±0.05 in blank control group,1.0 μmol/L Lipo-ASODN group and 2.0 μmol/L Lipo-ASODN group with the significant difference(P=0.00 ),and that of 1.0 μmol/L Lipo-ASODN group and 2.0 μ mol/L Lipo-ASODN group were significantly lower than the blank control group ( P =0.00,0.00).Hoechst 33258 staining showed that the apoptosis cells were obviously more in Lipo-ASODN group compared with blank control group.PDGFR-α ASODN transfection induced an increase of percentage of RPE cells in G0/G1 phase( F =206.70,P =0.00),and the apoptosis rates in 1.0 μmol/L Lipo-ASODN group and 2.0 μmol/L Lipo-ASODN group were significantly enhanced in comparison with blank control group ( 37.8 ± 1.3 vs 10.5 ± 0.1,61.2 ± 1.9 vs 10.5 ± 0.1 ) ( F =1808.90,P =0.00 ).Expression intensity of PDGFR-α mRNA in RPE cells in Lipo-ASODN groups was lower. ConclusionsBlocking the PDGFR-α expression with ASODN technology can suppress proliferation and induce apoptosis of RPE cells.Intensity of PDGFR-α mRNA expression in RPE cells is ASODN dose-dependent.ASODN targeted to PDGFR-α offers an experimental basis of the gene therapy for PVR.
