Objective: To observe the inlfuence of simvastatin combining ezetimibe on blood levels of glucose and lipids in patients of acute coronary syndrome (ACS) with impaired glucose tolerance (IGT).
Methods: A total of 316 patients with ACS and IGT were randomly divided into 2 groups: Treatment group, the patients received simvastatin 20 mg/day with ezetimibe 10 mg/day,n=160 and Control group, the patients received simvastatin 20 mg/day,n=156. All patients were treated for 24 months. Blood levels of total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) were observed at 6, 12 and 24 months of medication; fasting blood glucose (FBG), 2 hour postprandial blood glucose (2hPG), glycosylated hemoglobin (HbA1c) and the number of patients with new onset diabetes were examined at 6 days and 12, 24 months of medication.
Results:①In Treatment group, at 6 months of medication, blood levels of TC (mmol/L) and LDL-C (mmol/L) were (3.5 ± 0.5) and (2.1 ± 0.4) which were both lower than baseline levels (5.2±1.2) and (3.5±0.5),P<0.05; at 12 and 24 months, TC and LDL-C were (3.1 ± 1.0), (1.8 ± 0.6) and (3.0 ± 0.6), (1.8 ± 0.5), TC and LDL-C were consistently decreased, all P<0.05. In Control group, at 6 months of medication, TC and LDL-C were (4.0 ± 0.5) and (2.4 ± 0.5) which were both lower than baseline levels (5.3 ± 0.8) and (3.1 ± 0.4),P<0.05; at 12 and 24 months, TC and LDL-C were (3.8 ± 0.6), (2.3 ± 0.6) and (3.7 ± 0.5), (2.1 ± 0.7), allP<0.05. TC and LDL-C levels in Treatment group were lower than Control group at 6, 12 and 24 months of medication, allP<0.05.②In Treatment group, FBG (mmol/L) levels at 12 and 24 months were similar to 6 days,P>0.05; HbA1c at 12 and 24 months were similar to baseline,P>0.05; 2hPG (mmol/L) level at 24 months was higher than 6 days (9.5 ± 1.1) vs (8.7 ± 1.0),P<0.05; there were 26 patients with new onset diabetes at 24 months after medication. In Control group, 2hPG level at 24 months was higher than 6 days (9.6 ± 0.8) vs (8.7±0.7); there were 25 patients with new onset diabetes at 24 months after medication. The levels of FBG, 2hPG, HbA1c and the number of patients with new onset diabetes were similar between 2 groups, allP>0.05.
Conclusion: Ezetimibe combining simvastatin may better reduce blood lipids, while it had no real effect on blood glucose metabolism in patients with ACS and IGT.

Objective:To investigate the diagnostic value of high resolution CT for temporal bone traumatic facial nerve paralysis and the guidance significance for surgery.Method:Twenty-nine patients of traumatic facial nerve paralysis were investigated.The predictive diagnosis was made according to the clinical data and the image features of HRCT,then a comparative analysis of the preoperative image features and the surgical findings were carried out.Result:The trend of temporal bone fracture displayed on the CT scan was basically consisted with the surgical findings.The direct CT signs of facial nerve injury include the bone fracture line went through the tube,bone tube rupture or continuity interruption,while the indirect CT signs include local incrassation of the facial nerve,lower bone density of the tube,geniculate fossa expansion,oppressed facial nerve,et al.The predictive diagnostic accordance rates of all the image features were above 90%as to the surgical findings.Conclusion:High resolution CT could localize the trend of temporal bone fracture,and is helpful to estimate the extent of facial nerve injury and other complications.High resolution CT could provide reliable basis for clinical diagnosis and trotment.

OBJECTIVE:To establish the method for the determination of main components content and entrapment efficiency of transferrin modified vincristine-tetrandrine liposomes. METHODS:HPLC method was adopted to determine the content of vin-cristine. The determination was performed on ELITE C18 column with mobile phase consisted of methanol-15%triethylamine (70∶30)at a flow rate of 1.0 ml/min. The determination wavelength was set at 297 nm and column temperature was 30 ℃. The sample size was 20 μl. Free drug was isolated from liposomes by dextran gel column chromatography,and entrapment efficiency was deter-mined. RESULTS:The linear range of vincristine was 160-1 600 μg/ml (r=0.999 8,n=5) with average recovery of 99.20%(RSD=0.26%,n=9). RSD of precision test was 0.070%(n=5). The average content of vincristine in liposomes was 0.790 mg/ml(RSD=0.15%,n=3),and the average entrapment efficiency was 85.94%(RSD=2.08%,n=3). CONCLUSIONS:The method is accurate,reliable,simple and rapid,and can be used for the determination of the content and entrapment efficiency of vincristine in transferrin modified vincristine-tetrandrine liposomes.

OBJECTIVE:To prepare transferrin(TF)modified tetrandrine(TET)and vincristine(VCR)active targeting lipo-somes,and to optimize its formulation. METHODS:TF modified TET and VCR liposomes were prepared by ammonium sulfate gradient method. Using comprehensive score of encapsulation efficiency of TET and VCR as index,central composite design-re-sponse surface method was used to optimize and validate mole ratio of EPC/Chol,mole ratio of EPC/PEG2000-DSPE and TF mass fraction. RESULTS:The optimal formulation was that the mole ratios of EPC/Chol and EPC/PEG2000-DSPE were 1.5:1 and 20:1, TF mass fraction was 0.10%. The encapsulation efficiency of TET and VCR were 97.80% and 93.00%,respectively. The compre-hensive score was 94.44(n=3)which was close to the predicted value of 93.81. CONCLUSIONS:The optimal formulation is sta-ble and can be used for the preparation of TF modified TET and VCR liposomes.

OBJECTIVE:To study the anti-tumor effects of Vinblastine (VLB) hydrophilic group modified cationic liposomes in tumor-bearing mice. METHODS:Tumor-bearing model were induced by inoculating yellow ascites of S180 ascites tumor mice. Tumor-bearing mice were randomly divided into model group,VLB sulfate injection group,VLB liposomes group,VLB hydrophil-ic group modified liposomes group,VLB cationic liposomes group and VLB hydrophilic group modified cationic liposomes group, i.e. group A,B,C,D,E and F,with 18 mice in each group. Group A was given normal saline intravenously via mice tail,other groups were given VLB 1.5 mg/kg every 2 days for consecutive 5 times. The anti-tumor effects of different VLB preparations were compared,using living conditions,survival time,tumor volume and weight,and tissue pathological section as indexes. RE-SULTS:Compared with group A,B,C,D and E,the mice of group F were more active,and had longer survival time,smaller tumor volume and lighter tumor weight,with statistical significance(P<0.05). The tissue pathological section of mice in group F indicated that coagulation necrosis,disintegration,and dissolution of tumor cell nucleus. CONCLUSIONS:VLB hydrophilic group modified cationic liposomes have obvious anti-tumor effect,which are better than other VLB preparations.

Objective To randomly compare the therapeutic effect and safety between Levetiracetam (LEV) and Phenobarbital (PB) in the treatment of neonatal seizures.Methods A total of 61 infants with acute convulsion were randomly divided into 2 groups:LEV group (n =30) and PB group (n =31) during January 2013 to December 2014 in Urumqi Children's Hospital.All neonates received routine management including etiology treatment and adverse drug reaction monitoring.In the LEV group,subjects received oral formulation of LEV with initial loading dose 30 mg/kg,followed by 15 mg/kg twice a day.If the seizures were not controlled completely,PB treatment was added until seizures were completed controlled.If seizures were controlled quickly,the dose of PB was gradually reduced and LEV was used as monotherapy.The subjects in PB group received intramuscular or intravenous injection of PB with 10 mg/kg as the first dose,then 5 mg/(kg · d) oral PB was administered,if seizures were not controlled,LEV treatment was added,then dose of PB was gradually reduced until seizures were controlled completely,and then patients were switched to LEV monotherapy gradually.The drug adverse reactions were observed.Results (1) After LEV or PB monotherapy,66.7％ (20/30 cases) and 54.8％ (17/31 cases) of the subjects obtained sustainable seizure free respectively.Although,there was a higher control ratio in LEV group,but no significant difference was observed between the 2 groups (P ＞0.05).(2) LEV group (16/30 cases,53.33％) had higher rapid seizure control ratio with seizure controlled within 24 h after first dosage administration than that of PB group (8/31 cases,25.80％),and there was significant difference (x2 =4.841,P =0.028).Further more,if adding the cases who had to change to use another comparative one (LEV or PB) due to their seizures failure control with the first one treated,LEV group (21/44 cases,47.72％) still had higher rapid seizure control ratio in total patients than that of PB group(10/41 cases,24.39％),and there was significant difference (x2 =4.988,P =0.026).(3) Eight cases who changed to LEV after PB as the first treatment drug failed obtained sustainable seizure free.(4) One case in PB group with transient urinary retention was observed but the symptom disappeared 36 h after PB withdrawal,and no significant drug adverse reaction was observed in LEV group.Conclusion LEV is more rapid and safe for seizure control of neonates than PB.
