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.

Methods:Amomum viosum and the other samples be-longing to the same genera were collected and identified by experts in the domain. DNA was isolated using commercial kits. The prim-ers and probe were designed according to the conserved region of ITS in amomum viosum. The reaction conditions were optimized to es-tablish the fluorescent quantitative PCR method for the rapid detection of amomum viosum. Results:The fluorescent quantitative PCR method for the rapid detection of amomum viosum was set up. The method could identify amomum viosum successfully, while those samples in the same genera were without amplification curves. Conclusion: Amomum viosum can be identified rapidly by fluorescent quantitative PCR besides the traditional identification by experts.

Sixty diabetic patients and twenty normal controls were studied. The results showed that: 1) Counter-immuno-electrophoresis is a sensitive and simple test suitable for the detection and monitoring of diabetic microproteinuria; 2) The proteinuria in diabetic nephropathy is glomerular in origin which is supported by the finding of a marked increase in urinary albumin excretion and a normal level of urinary ?2-microglobulin; 3) The serum ?2-microglobulin appears to be a more sensitive index than serum creatinine and creatinine clearance rate for the detection of impairment of renal function in diabetic patients; 4) Diabetic nephropathy is related to glycemic control and duration of diabetes mellitus.

Objective To investigate the interaction of in vitro antibacterial activity between cefoperazone-sulbactam and imipenem against carbapenem-resistant Acinetobacterbaumannii.Methods The minimum inhibitory concentrations (MIC) of imipenem and cefoperazone-sulbactam against Acinetobacter baumannii were detected and the fractional inhibitory concentration (FIC) index of imipenem/cefoperazone-sulbactam combination was calculated by broth micro-dilution method.The interactions of imipenem and cefoperazone-sulbactam were assayed by K-B agar plate method.Results The MIC50 of cefoperazone-sulbactam and imipenem were both 16 mg/L,and MIC90 of the two drugs were both 64 mg/L.Among the 26 strains of Acinetobacter baumannii,16 strains had FIC indexes ≤0.5,and 10 had FIC indexes≥2.0.K-B agar plate assay showed that the cefoperazone-sulbactam/imipenem combination was synergistic for strains with FIC indexes≤0.5,and antagonistic for strains with FIC indexes ≥ 2.0.Conclusions Imipenem in combination with cefoperazone-sulbactam can be either antagonistic or synergistic against carbapenem-resistant Acinetobacter baumannii.The clinical use of cefoperazone-sulbactam/imipenem combination for the treatment of carbapenem resistance Acinetobacter baumannii infections should be cautious in case of antagonism.

Objective To compare the effect of percutaneous balloon compression (PBC) versus percutaneous radiofrequency thermocoagulation treatment (PRFT) on idiopathic trigeminal neuralgia in elderly patients. Methods The 87 patients with idiopathic trigeminal neuralgia were enrolled, 42 patients were treated by PBC (PBC group), and the other 45 patients were treated by PRFT (PRFT group). The effects of two therapies were evaluated after treatment. Results The early response rate (92.9% vs. 95.6%) and cure rate (88.1% vs. 88.9%) of PBC group versus PRFT group had no significant differences (both P＞0.05). The inhibitory response rate of trigeminal nerve was significantly greater in PBC group than in PRFT group after treatment (69.0% vs. 35.6%, P＜0.05), and 1 patient had cardiac arrest in PBC group. The two groups had different degrees of facial numbness and sensory dysfunction. The 39 patients treated by PBC had numbness in three divisions of trigeminal nerve, while 43 patients treated by PRFT had the high selection and showed the main numbness in the ill division of trigeminal nerve. The chewing gravis rate was higher in PBC group than in PRFT group (71.8% vs. 20.9%, P＜0.05). There was no neuralgia recurrence in both groups during 6 monthe′ follow-up. Conclusions The effect of treating the elderly patients with idiopathic trigeminal neuralgia is similar by PBC and PRFT. The PBC therapy under general anesthesia is more convenient for patients who can not cooperate.The PRFT has much higher selectivity in trigeminal nerve damage, lower inhibition rate of the trigeminal nerve, and less influence on the masticatory muscle function.

Objective To investigate the effect of down-regulation of transient receptor potential melastatin 8 (TRPM8) on the proliferation and apoptosis of human bladder transitional cell carcinoma cells T24.Methods shRNA targeting TRPM8 was designed and synthesized, and then transfected into the T24 cells via lipofectamine 2000 mediation.The proliferation and apoptosis of T24 cells were detected with methyl thiazolyl tetrazolium (MTT) assay and flow cytometry.Expression of extracellular regulated kinase (ERK), cyclin D1, and Bcl-2 were detected with Western blot.Results TRPM8-targeted shRNA downregulated TRPM8 expression of T24 cells.MTT assay showed a significant acceleration of the proliferation of shRNA interference group compared to blank and control groups (P ＜0.01).Compared to control group, cell apoptosis rate was significantly higher in shRNA interference group (P ＜ 0.01).In addition, the expressions of PI3K, cyclin D1, and Bcl-2 were decreased in shRNA interference group.Conclusions Down-regulation of TRPM8 can induce inhibition of proliferation and promotion of cell apoptosis in human bladder transitional cell carcinoma cells T24 via regulating PI3K.It might be regarded as a novel target for clinical diagnosis and gene therapy of bladder cancer.

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.
