Objective To explore the levels of serum interleukin-6 and interleukin-18 in newly diagnosed type 2 diabetes mellitus (T2DM) and investigate their roles. Methods The serum interleukin-6 and interleukin-18 levels were detected in 50 newly, diagnosed T2DM patients (T2DM group) and 40 normal subjects (control group). Fasting blood glucose, fasting insulin, blood lipid, body mass index (BMI) and waist/hip ratio (WHR) were measured. HOMA-IR and HOMA-β were calculated. Results The serum interleukin-6 and interleukin-18 levels in T2DM group were significantly higher than those in control group [(2.56 ± 1.09) ng/L vs (1.81±0.80) ng/L, (5.38±0.91) ng/L vs (4.62±0.59)ng/L] (P <0.01).Interleukin-6 level was positively correlated with HbA_1c,while interleukin-18 level was positively correlated with BMI and WHR. Interleukin-6 and interleukin-18 levels were positively correlated. Interleukin-6 and interhukin-18 could predicted the insulin resistance. Conclusion Interleukin-6 and interleukin-18 take part in the development of T2DM, and can be related to the insulin resistance.

Insulin resistance is the important base of the pathogenesis of type 2 diabetes.Physical exercise can improve insulin sensitivity.This article presents an overview of how physical exercise improves insulin resistance and helps the prevention and treatment of diabetes mellitus by analyzing its influence on the level of insulin receptor and post-receptor and adipose cell cytokine.

Objective To investigate the effect of EGB on SOD, MDA of ventilator-induced lung injury in rats and its possible mechanisms. Methods Thirty male SD rats were randomly divided into 3 groups: control group (C group), high tidal ventilation group (H group) and EGB group (E group). The setting mechanical ventilation was VT=30 mL/kg, RR=40/min, I/E=1/3, PEEP=0 cmH2 O and FiO2=21%. The broncho-alveolar lavage fluid (BLAF) and serum were obtained for determination of the levels of SOD and MDA at the end of 4 h mechanical ventilation. The Lungs were removed, and the wet-to-dry weight ratio (W/D) and pulmonary pathologic changes were measured. Results As compared with C group, W/D and the levels of MDA were significantly increased in H group, but the levels of SOD were reduced in H group. As compared with H group, W/D and the levels of MDA were significantly decreased in E group, but the levels of SOD were increased in E group. Pulmonary pathologic changes were alleviated in E group comparing with H group. Conclusion EGB injection may have a protective role against hyperoxia and induced pulmonary damage in rats.

Background and purpose:Dihydrofolate reductase (DHFR) is expressed highly in platinum-resis-tant ovarian cancer. This study aimed to explore the relationship between the silence ofDHFR gene and platinum drug resistance in ovarian cancer, and lay the foundation for the treatment of platinum-resistant ovarian cancer.Methods:To design targeting hairpin siRNA ofDHFR gene, the optimal siRNA silent sequence was selected, and lentiviral vector carryingDHFR gene was constructed successfully, named DHFR-pGCSIL-SKOV3 cell. Flow cytometry was used to detect the cell apoptosis of DHFR-pGCSIL-SKOV3 cells, pGCSIL-SKOV3 cells and SKOV3 cells incubated in various concentrations of cisplatin (2.5, 5.0, 10.0 and 20.0 μg/mL) at different time points (24, 48 and 72 h), and cell cycle changes of these cells at IC50 cisplatin concentration (4.4 μg/mL). High performance liquid chromatography was used to test intracellular concentration of cisplatin at different induction concentration of cisplatin (2.5, 5.0 and 7.5 μg/mL) and various time points (24 and 48 h). Ultrastructural changes of these cells at concentration of cisplatin IC50 (4.4 μg/mL) were observed by transmission electron microscope.Results:After annealing double-strand nucleotide was connected to pGCSIL/GFP vector, sequencing result was correct. SKOV3 cell were transfected with virus particles followed by Western blot detection of interference effect. Flow cytometry was used to detect apoptosis in three groups of cells, and increased apoptosis rate was found at the raised cisplatin concentration (2.5, 5.0, 10.0 and 20.0 μg/mL) at 24, 48 and 72 h in DHFR-pGCSIL-SKOV3, pGCSIL-SKOV3 and SKOV3 cells. The apoptosis rate in DHFR-pGCSIL-SKOV3 was signiifcantly higher than that in pGCSIL-SKOV3 and SKOV3 cells at 24 and 48 h (P<0.05). Flow cytometry was adopted to test cells cycle of 3 groups at different time period under IC50 cisplatin concentration (4.4 μg/mL), the results indicated that G0/G1 phase cell rate of DHFR-pGCSIL-SKOV3 was much more than the others, of which G2/M and S phase cell rates were on the contrary. While at 72 h, 3 groups were mainly G2/M and S phase cell rates, DHFR-pGC-SIL-SKOV3 was lower than the others. High performance liquid chromatography method was used to detect intracellu-lar cisplatin concentration at 24 and 48 h after the cells were incubated at various concentrations of cisplatin (2.5 and 5.0μg/mL). The results showed the intracellular cisplatin content of DHFR-pGCSIL-SKOV3 cell was signiifcantly higher than that of pGCSIL-SKOV3 and SKOV3 cells. However, after incubation at cisplatin concentration of 7.5 μg/mL, the intracellular cisplatin content of DHFR-pGCSIL-SKOV3 cell was signiifcantly lower than that of pGCSIL-SKOV3 and SKOV3 cells at 24 h, while higher than pGCSIL-SKOV3 and SKOV3 cells at 48 h (P=0.034,P=0.014). We observed ultrastructural changes of three different cell lines induced by IC50 cisplatin concentration(4.4 μg/mL) at different time points by the electron microscope. We found that the microiflaments were increased and gathered together and mitochondrial structure was also changed obviously without the drug. However, there was rare microiflament in three groups of cells at 24 and 48 h, while at 72 h, obviously increased inordinate microiflaments were observed.Conclusion:We successfully constructed pGCSIL lentivirus interference carrier carryingDHFR gene. The research indicates that down-regulation ofDHFR gene is related to cisplatin drug resistance in ovarian cancer. The results laid the foundation for us to investigate the molecular mechanisms of multidrug-resistance in tumor.
