OBJECTIVE:To determine the content of 5 kinds of heavy metal elements in Astragalus membranaceus from Longxi of Gansu province,i.e. Pb,Cd,Cu,As,Hg. METHODS:Wet digestion pretreatment was carried out for samples and atomic absorption spectrometry (AAS) was used for the determination of heavy metal elements. RESULTS:The contents of 5 kinds of heavy metal elements in A. membranaceus from Longxi of Gansu Province were lower than the limit. CONCLUSION:AAS method can accurately determine the content of heavy metal elements in A. membranaceus.

Isoelectric focusina Electrophoresis(lFE)was use to detenmine the isoelectric point of main protein composition in Chinese Traditional Medicine (TCM ) either of animal origin Such as (EuPotyPhage sinenses)orfrom fruit or seed of plants (such as the seed of CeIosia urgeatea). Results showed that their IFE bands werealways quite distinct,which can be used to assess their quality and to distinguish them from confusable varieties.

Delicacy management proves a pressing need in cost management of medical service items in the current hospital operation.This paper first covered the methodology and system of hospital costing.It went on to describe the costing for four major medical service items in a quarter in 2011 using the activity-based costing method with the ultrasonographic section of a large hospital as an example.The outcomes were compared to the traditional costing method and the statutory pricing standards,resulting in the proposal and recommendation on reforming the costing methodology of service item pricing,and applying the activity-based costing management of medical service items in the hospital.

Objective To evaluate the feasibi1ity and efficacy of transcatheter closure of perimembranous and muscular ventricular septal defects (VSD) using the new Amplatzer membranous and muscular VSD occluder and observe the effect of membranous VSD occluding procedure on atrioventricular(AV) conductive system.Methods Twelve patients (7 males,5 females) with perimembranous VSD and two patients (1 male,1 female) with muscular VSD underwent an catheter closure using the new Amplatzer membranous and muscular VSD occluder.All patients who were eligible for device closure by means of cardiac Doppler echocardiography were routinely measured the parameters of blood dynamics before catheter closure. Artery-venous track was set up under the X-ray fluoroscopy,transesophageal (TEE) or transthoracic echocardiography (TTE) guidance. Devices were released in the right ventricular side.Twelve patients with perimembranous VSD underwent the cardiac electrophysiologic examination,including atrioventricular conductive time (AV interval) and atrioventricular nodal refractory time,before and after catheter closure.A11 patients were followed up at 2 weeks,1 month,3 months and 6 months after the procedures.Results The devices were deployed successfully in 14 patients.There was complete closure in 12 patients immediately,and tiny (

OBJECTIVE:To establish the GC-MS fingerprint spectrum of volatile components in Danqi piantan capsule. METH-ODS:GC-MS was performed. HPLC conditions:The column was BPX 5,temperature of injection was 250 ℃,respectively;carri-er gas was He,flow rate was 1 ml/min,split injection,split ratio was 50:1 and volume injection was 0.02 μl. MS conditions:ion source was EI,bombarding energy was 70 eV,temperature of ion source and transmission line was 200 ℃ and 250 ℃,respective-ly;scan range was 40-500 amu,solvent delay of 2 min. The peak with largest chromatographic peaks areas was reference peak,com-mon peaks of 10 batches of Danqi piantan capsule were analyzed. Similarity evaluation system for chromatographic figerprint of TCM was adapted for the similarity analysis and NIST standard MS database was used to retrieve and identify the common peak. RESULTS:There were totally 13 common peaks in the 10 batches of Danqi piantan capsule with similarity degree>0.92;accord-ing to the verification,the fingerprint spectrum was a dapted for the similarity analysis and reference fingerprint of 10 batches of Danqi piantan capsule showed good consistency. The No.3 peak was Angelica sinensis unique,the No.2,4,5,7,8,12 peak was Acorus tatarinowii unique. CONCLUSIONS:The established method is specific and stable,and can provide basis for the quality as-sessment for Danqi piantan capsule.

OBJECTIVE:To compare the efficacy and safety of only paroxetine vs. paroxetine combined with alprazolam in the treatment of diabetes complicated with anxiety and depression. METHODS:Totally 86 patients with diabetes complicated with anxi-ety and depression were randomly divided into observation group and control group. The patients in observation group were given paroxetine 20 mg,qd,and alprazolam 0.4 mg,tid;patients in control group were given paroxetine alone. The treatment course lasted for 8 weeks in 2 groups. The clinical data was compared,including fasting plasma glucose(FPG),2 h postprandial glucose (2 h PG),glycated hemoglobin (HbA1c),cortisol,adrenocorticotropic hormone (ACTH) levels and scores of Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD). The adverse reactions were observed. RESULTS:After treatment,FP-BG,2 h PG,HbA1c,cortisol,ACTH levels and scores of HAMA and HAMD in observation group were significantly lower than control group,with significant difference(P<0.05). There were significant differences in the incidence of adverse reactions be-tween 2 groups(P>0.05). CONCLUSIONS:Compared with paroxetine alone,paroxetine combined with alprazolam can improve more in blood glucose,endocrine levels and adverse mood symptoms in the treatment of diabetes complicated with anxiety and de-pression,with similar safety.

Objective To investigate the changes of cholesterol efflux,the scavenger receptor class B type Ⅰ(SR-BI) protein expression in THP-1 maerophage derived foam cells treated with Lippolysaecharide (LPS), and to discover the role of NF-κB pathway in this process.Methods The foam cells were treated with LPS along or treated with N-p-Tosyl-L-phenylalanine chloromethyl ketone(TPCK) for 24 h.The protein levels of SR-BI and intranuclear NF-κB p65 were measured by Western blotting.Cellular lipid accumulation was determined by high performance liquid ehromatograpby analysis.Cholesterol efflux was determined by FJ-2107P type liquid scintillator.Results The expression of SR-BI was decreased after treated with LPS,while the intranuclear NF-κB p65 protein level was increased by LPS.The results also showed that cellular lipid accumulation was increased ,while the cellular cholesterol efflux was decreased in THP-1 maerophage derived foam cells after exposed to LPS for 24 h and these changes can be reversed partly by pretreatment with TPCK.Conclusion LPS could down-regulate the expression of SR-BI, promote the accumulation of lipid and decrease cellular cholesterol efflux in THP-1 maerophage derived foam cells ,which should be related to the TLR4/NF-κB dependent pathway.
