With the help of macroreticular resin,the reservation rate of TSA could reach 87.52%.Its purity was 77.74%,comparing with crude extract,increased by 3.6 times. CONCLUSION: The method of purifing TSA of RSM with D101 macroreticular resin is feasible,it could be applied to industrialized production of TSA of RSM.

Objective To investigate the emotional distress and coping style during acute stage in patients following acute traumatic injury, and the relationship in different coping patterns and emotional distress. Methods A total of 118 patients with acute traumatic injury were included in our investigation.Emotional distress was assessed with the Hospital Anxiety and Depression scale. Coping style was measured with the Medical Modes Questionnaire. Descriptive analysis, independent samples t test and multiple linear regression analysis were used. Results Emotional distress occurred in 50.00% of the patients with acute traumatic injury,22.40% patients only presented anxiety, 17.30% patients only presented depression, and 10.20% patients presented both anxiety and depression. Yielding and avoidance coping styles were more frequently used in patients with depression. Conclusions Incidence of emotional distress was highly fre-quently, many factors were associated with patients" affection reaction.

OBJECTIVE:To establish an RP-HPLC method for determination of plasma concentration of glimepiride (GM) in Beagle dogs. METHODS: Plasma sample was separated on Agilent Eclipse XDB-C8 column with column temperature kept at 30 ℃,and the mobile phase consisted of acetonitrile-methanol-10 mmol?L-1 potassium dihydrogen phosphate (65∶40∶95,pH value adjusted to 7.2) at a flow rate of 1.0 mL?min-1. The UV detection wavelength was set at 227 nm. Plasma sample were pretreated by liquid-liquid extaction with gemfibrozil as an internal standard. Plasma concentrations of GM in 6 Beagle dogs at different time points were determined after a single sublingual dosing of 2 mg GM spray. RESULTS: The linear range of GM was 50～2 500 ng?mL-1 with a lowest detection limit of 20 ng?mL-1. The intra-day RSD and inter-day RSD were all less than 15%. The extraction recovery rate was 71.27%～103.5%,and the methodological recovery rate was 87.97%～ 98.95%. CONCLUSION: This method is simple in sample treatment and sensitive,and it is applicable for analysis of GM in biological sample.

Objective To investigate the clinical effect of continuous blood purification therapy in patients with severe heart failure and renal failure.Methods The clinical data of 38 patients with severe heart failure and renal failure treated by continuous blood purification were analyzed retrospectively.Heart rate,mean blood pressure, APACHE II score,Boston score,blood biochemistry,blood gas analysis and cardiac function changes were compared before and after the treatment of continuous blood purification.Results After treatment 12h and 72h,patients breath-ing[(19.24 ±2.88)times/min],heart rate[(88.57 ±15.68)times/min],APACHE Ⅱ [(14.28 ±3.26)points] and the score of Boston[(6.27 ±1.25 )points]were significantly decreased compared with those before treatment [(35.68 ±5.97)time /min,(131.24 ±24.26)time /min,(26.34 ±5.96)points,(17.88 ±2.87)points],and the differences were statistically significant (t =3.13 3.45,2.12,4.11,3.67,5.68,3.44,609,all P <0.05).38 cases of severe heart failure with renal failure after continuous blood purification treatment,markedly effective in 16 cases, effective in 12 cases,ineffective in 10 cases,the total effective rate was 73.68%.Patients after continuous blood purification treatment,the SCr[(168.15 ±31.16)μmol/L],BUN [(13.13 ±3.44)mmol/L]were significantly decreased.pH[(7.41 ±0.13)],HCO3 [(25.57 ±5.11)mmol/L],PaO2 [(88.26 ±7.72)mmHg],SaO2 [(96.43 ± 3.14)%]and blood biochemistry and blood gas index decreased markedly,and the differences were statistically significant (t =4.55,3.21,2.11,3.45,673,4.21,all P <0.05).After the examination of echocardiography,stroke volume (SV)[(59.31 ±6.58)mL],cardiac output (CO)[(4.57 ±0.62)L/min]and left ventricular ejection fraction (LVEF)[(68.12 ±4.88)%]increased significantly compared with before treatment,and the differences were statistically significant (t =4.33,5.12,367,all P <0.05).Conclusion Continuous blood purification could effectively maintain the hemodynamic stability of patients,and is safe and effective in the treatment of severe heart failure with renal failure.

Objective To explore the efficacy of radiofrequency ablation (RFA) and ethanol ablation(EA) for treating partially cystic thyroid nodules.Methods One hundred and twenty-four patients with a single partially cystic thyroid nodules which caused pressure symptoms or cosmetic problems were treated with RFA (n =42),EA (n =39) or RFA + EA(n =43).The inactivation rate of the nodule,tumor volume reduction rate,symptom scores (0-10) and complications were evaluated before and after treatment.Results The mean inactivation rate of RFA,EA and RFA + EA groups was (87.50 ± 5.77) ％,(57.00 ± 6.12) ％,(90.03 ± 5.39) ％,respectively.The inactivation rate of the nodule was negatively related to the volume of the solid part of the nodule.As to nodules with the volume ranging from 30 to 45 ml,the inactivation rate of RFA group was lower than RFA + EA group.Nodule volume reduction ratio (percentage) at 12-month follow-up was 90.45％ for RFA group,69.88％ for EA group,and 93.28％ for RFA + EA group.Regarding mean volume reduction,there were no difference between RFA + EA and RFA group (P ＞0.05),while there were significant differences between RFA + EA and EA group (P ＜0.05),also RFA and EA group (P ＜0.05).The patients in EA subgroup with cystic part percentage less than 50％ had a unsatisfying outcome (the volume reduction ratio less than 50％),while there were no differences(P ＞0.05) on the volume reduction ratio of nodule based on cystic part percentage between RFA group and RFA + EA group.The rate of the complication was 7.14％,2.56％,2.33％,respectively.Conclusions Ultrasound-guided percutaneous aspiration combined with RF ablation yielded better results than EA ablation.But due to ethanol ablation being less expensive and simpler to perform than RFA,ethanol ablation should be the first line treatment technique for benign thyroid nodules with cystic part percentage more than 50％,while radiofrequency ablation as first-line treatment for benign thyroid nodules with cystic part percentage less than 50％.

AIM: To explore the regulatory mechanism of n erve growth factor (NGF) on neurokinin A in the experimental asthmatic guinea pi g. METHODS: Radioimmunoassay was used to determine the alteration of neurokinin A levels in the lower respiratory tract and visceral sensory afferent sites while NGF was absent (inhalation of NGF antibody through nasal cavity) in the asthmatic guinea pig. RESULTS: The contents of neurokinin A in the trachea, bronchus, lung, C 7-T 5 spinal ganglia and the correspondent spinal dorsal horn, nodose ganglia and solitary nucleus area in the experimental asthmatic guinea pig with the absent of NGF in the respiratory tract were much lower than those in the as thmatic and control groups (P

OBJECTIVE In order to supply the basis of reasonable use of antibiotics,investigation of the change in distribution and drug-resistance of isolated enterococci was made in our hospital.METHODS Enterococci were cultured,isolated and identified with ATB Expression microbe identification system.Drug-resistance was detected with ATB ENTEROC and was statistically analyzed.RESULTS A total of 1 354 strains of enterococci were isolated from 50 148 clinical specimens,the isolation rate was 2.7%.The main strain of enterococci was Enterococcus faecalis.E.faecium was the second one.The isolation rate of enterococci,which were the highest in urine specimens,was increasing in sputum specimens year by year.The drug-resistance rate of enterococci to erythromycin,rifampin,ciprofloxacin and levofloxacin was high,but it was still sensitive to vancomycin and teicoplanin.CONCLUSIONS Great changes have taken place in bacterial distribution and drug-resistance of isolated enterococci,and the drug-resistance of strains of enterococci differed greatly.To insure effective treatment and decrease the infection of enterococci in hospital,the antibiotics sensitive to enterococci should been used on the basis of drug-resistance test when the infection of enterococci was treated clinically.

AIM To compare the new methods which can be used fo r soring the stages of rat sleep. METHODS Cortical EEG and hippocampal potential(HP) were collected by implanted electrodes in freely moving rats. Gravity frequency (f g) and the complexities(Kc,C 1), were calculated. According to the characteristics of each stage and by studying the histogram of f g, Kc and C 1, the stages of rat sleep were distinguished. RESULTS The methods of f g, Kc and C 1 can distinguish the Waking, nonrapid eye movement(NREM) and REM sleep well. Comparing the results of visual and our analysis, the rate of accordance is above 85%, and the analysis based on the complexity measure is more believable than that based on the f g. CONCLUSION The gravity frequency and the complexities of Kc,C 1 can be used to distinguish the different stages of rat sleep.
