The qualitative and quantitative analysis of active constituents in Fructus Psoraleae is presented by high-performance liquid chromatography (HPLC) coupled with different detections.Extracts of Fructus Psoraleae were examined by HPLC with ion trap mass spectrometry (IT-MS) and 18 major compounds of coumarins,benzofuran glycosides,flavonoids,and meroterpene were identified.The determination of four major constituents including bavachin,isobavachalcone,bavachinin,and bakuchiol was accomplished by HPLC with UV,MS,and electrochemical detection (ECD).These methods were evaluated for a number of validation characteristics (repeatability,LOD,calibration range,and recovery).ECD obtained a high sensitivity for analysis of the four components; MS provided a high selectivity and sensitivity for determination of bavachin,isobavachalcone,and bavachinin in negative-ion mode.After optimization of the methods,separation,identification.and quantification of the four components in Fructus Psoraleae were comprehensively tested by HPLC with UV,MS,and ECD.

Objective To discuss the health education modes in order to promote the effect of health education for TURP(transurethral resection of prostate)patients and their family members.Methods A total of 380 cases after TURP were divided into the observation group and the control group at random with 190 cases in each group.The discharge instruction for the patients and their family members in the observation group was in the form of health education prescription,while the discharge instruction for the control group was in the form of oral instruction.The awareness rate of disease-related knowledge and incidence of complication were compared between the two groups. Results The awareness rate of disease-related knowledge in the observation group was higher,and incidence of complications was lower than that of the control group.Conclusions The application of health education prescription in the discharge instruction for the patients after TURP can guarantee the effectiveness of health education,simultaneously decrease the incurrence of complications and improve the life quality of patients.

OBJECTIVE:To analysis and identify the liposoluble constituents extracted with supercritical CO 2 fluid ex-traction(SFE)from atractylodes macrocephala by gas chromatography-mass spectrometry(GC/MS).METHODS:Volatile oil was extracted from atractylodes macrocephala,to analsis and identify the chemical components in liposoluble constituents with GC/MS,DB-5MS capillary column was the chromatographic column and helium was carrier gas,the flow rate was 2.0ml/min,and the column temperature was raised from 70℃ to 250℃ at an increasing rate of 10℃/min.EI ion sources were adopted in mass spectra.RESULTS:A total of 19 chromatographic peaks were separated and identified,most of which were unsatu-rated fatty acids and esters,accounting for 96.2% of the total peak area.CONCLUSION:Using GC/MS,the chemical com-position of the liposoluble constituents in atractylodes macrocephala can be analyzed,which provides references for the further exploitation and utilization of atractylodes macrocephala.

OBJECTIVE:To establish a HPLC method for the determination of yohimbine in corynanthe yohimbe K.schum.METHODS:The analysis was performed on C18 column with column under room temperature.The mobile phase consisted of methanol-phosphoric acid buffer-triethylamine(30∶ 70∶ 0.5,pH5.0)with a flow rate of 1.0mL? min-1.The wavelength was set at 270nm.RESULTS:There was a good linear relationship when the sample size of yohimbine was over a range of 10～ 1 000? g? mL-1(r=0.999 8),with recovery at 96.5% and precision at 1.23%.CONCLUSION:This method was simple and reliable,and suitable for the determination of content of yohimbine.

Objective:To establish an HPLC method to determine the content of rosmarinic acid in Wuling capsules. Methods:The chromatographic column was Linksil-ODS (250 mm × 4. 6 mm,5 μm) with a gradient elution mode at the flow rate of 0. 8 ml· min-1,and the mobile phase was acetonitrile-water (32∶68) including 0. 5% acetic acid. The detection wavelength was 319 nm, the column temperature was 25 ℃ and the injection volume was 20 μl. Results: The linear range was 2-80 μg·ml-1 and the standard curve showed good linear regression within the range(r=0. 999 8). And the average recovery was 97. 07﹪ (n=6) with the inter-day precision (RSD) of 1. 35 %. Conclusion:The method is accurate and rapid with good reproducibility in the determination of ros-marinic acid in Wuling capsules, which can be used to control the quality of rosmarinic acid in Wuling capsules.

Objective:To establish a rapid and sensitive method for the determination of carbendazim in honeysuckle flowers by LC-MS/MS. Methods:The sample was extracted by acetic ether. The mass spectrometer was operated in the positive ionization elec-trospray ( ESI) mode using selection ion monitoring ( SIM) . The transition m/z 192→160 was used to quantify carbendazim. Results:The method had a satisfactory linearity within the range of 50-5 000 ng·ml-1 for carbendazim (r=0. 999 4), the limit of detection (LOD) was 2. 0 ng·ml-1, and the mean recovery was 93. 2%. Conclusion:The method of LC-MS/MS is sensitive, simple and ac-curate,which is proved to be suitable for the determination of carbendazim in honeysuckle flowers.

Objective To investigate the relationship between white-matter hyperintensities (WMHs) and hemorrhagic transformation and neurological outcome at 3 months after recombinant tissue plasminogen activator (rt-PA) treatment in patients with acute ischemic stroke.Methods The chnical data of 132 patients with acute ischemic stroke who had received intravenous rt-PA therapy were retrospectively reviewed.The severity of WMHs according to the modified Schelten scale was assessed.Hemorrhagic transformation included hemorrhagic infarct (HI) and cerebral parenchymal hemorrhage (PH).Hemorrhagic transformation after thrombolytic therapy and clinical neurological outcome based on modified Rankin scale (mRS) at 3 months was also analyzed.Favorable neurological outcome as mRS 0-1 score and unfavorable neurological outcome as mRS 2-6 scores was defined.Results Hemorrhagic transformation was found in 26 patients (19.7％,26/132) among 132 patients receiving intravenous rt-PA treatment.Seventeen patients were HI type and 9 patients were PH type.Multiple Logistic regression analysis showed that baseline American National Institute of Health Stroke Scale (NIHSS) score,diastolic pressure,WMHs score was not correlated with HI type hemorrhagic transformation (P ＞ 0.05) ; and WMHs score was not correlated with PH type hemorrhagic transformation (P ＞0.05),but baseline NIHSS score,diastolic pressure was the independent risk factor of PH type hemorrhagic transformation (P ＜ 0.05).Dicho-Logistic regression analysis showed that WMHs score was the independent risk factor of unfavorable neurological outcome (OR =1.136,95％ CI 1.037-1.245,P =0.008).Conclusion Severe WMHs are not associated with hemorrhagic transformation but independently associated with unfavorable neurological outcome after thrombolytic therapy in patients with acute ischemic stroke.
