In contrary ,the collagen content of liver tissue was higher in DM group than in NC group [(134.54 ± 18.78) vs (64.52 ± 21.51) mg/g ,P<0.01]. Conclusion The effect of type 2 diabetes on the collagen in different organs is different. The collagen content decreases in the femoral and skin tissue but increases in the liver.

OBJECTIVE: To establish a LC-MS/MS method for the determination of sufentanil plasma concentration in patients receiving intravenous combined anesthesia. METHODS: After adding 2 mol · L-1 NaOH as the basification reagent, sufentanil was extracted from plasma by ether. Then sufentanil was determined by LC-MS/MS using fentanyl as the internal standard. Separation was carried on a Diamonsil C18 column (4.6 mm × 150 mm, 5 μm) with a mobile phase of methanol-5mmol · L-1 ammonium acetate-acetic acid (74: 26: 0.5) at the flow rate of 0.5 mL · min-1. TIS source was applied and operated in positive ion mode. Quantitative determination was performed using multiple reaction monitoring (MRM) of m/z 387.2 → m/z 238.2 for sufentanil, and m/z 337.4 → m/z 188.2 for fentanyl. RESULTS: The calibration curve was in good linearity over the range of 0.01-1.00 μg · L-1(r=0.9981). The extraction recovery for sufentanil were more than 64.2%, while the intra-day and inter-day precision (RSD) were lower than 11.6%. CONCLUSION: The method is shown to be simple, rapid, accurate and sensitive, which can be applied to the determination of sufentanil and the pharmacokinetics study of sufentanil in patients receiving intravenous combined anesthesia.

Objective: To evaluate the clinical efficacy and safety of ticagrelor in the patients with acute coronary syndrome ( ACS) . Methods:A retrospective study was applied to investigate the ACS patients treated with ticagrelor in our hospital from July to December in 2015. The basic information of patients, drug administration, platelet aggregation induced by ADP, major adverse cardio-vascular events ( cardiac death,nonfatal myocardial infarction,target vessel revascularization and stent thrombosis) , and adverse drug reactions ( ADR) were recorded. The incidence of end point events was calculated and the change of platelet aggregation induced by ADP before and after the drug administration was analyzed by SPSS statistical software. Results:A total of 161 patients were collected. The incidence of cardiovascular adverse events was 1. 2%, while the incidence of adverse drug reactions was 30. 4% including bleeding (15. 5%) without severe bleeding events and dyspnea (10. 6%) with 3 severe ones. The platelet aggregation rate before and after the ticagrelor treatment respectively was (54. 96 ± 14. 654)%and(24. 37 ± 13. 183)% in 122 patients with low reaction to clopidogrel( P<0. 01). Conclusion:Ticagrelor at the recommended dose can further reduce the platelet aggregation induced by ADP. In spite of high incidence of ADR, ticagrelor has slight ADR with good tolerance.
