OBJECTIVE:To compare the contents of trace elements in different parts of Piper kadsura.METHODS: Trace elements in leaf, micro-stem and macro-stem of P. kadsura were determined with inductive coupled plasma emission spectrometer. The contents of trace elements in the different parts were analyzed and compared. RESULTS: The content of Mg in the leaf was the highest among all trace elements, followed by Fe,Mn,Zn,Ti,Sr,Ba,Pb,B,Cu,Ni,Cr,Cd.The content of V in the macro-stem was higher than in the other parts. The contents of trace elements in micro-stem were all lower than in the other parts except of Sn. CONCLUSION: The leaf and stem of P. kadsura maybe has some complementary pharmacological function.

Objective:To study the effect of melatonin(Mel),a potent antioxidant,on the oxidative stress and the activity of hypothalamo-pituitary-adrenal axis in diabetic rats.Methods:Male SD rats were assigned to the following 4 groups:normal control(treated with 2% ethyl alcohol lavage\[NC,n=6\]),diabetes mellitus control(treated with 2% ethyl alcohol lavage \[DM,n=7\]),diabetes mellitus model group 1(treated with Mel lavage \[10 mg?kg-1?d-1,DM+Mel1,n=6\]),diabetes mellitus model group 2(treated with Mel lavage \[0.2 mg?kg-1?d-1,DM+Mel2,n=6\]).Diabetes in DM group,DM+Mel1 group and DM+Mel2 group was induced by intraperitoneal injection of streptozotacin(65 mg/kg).Blood glucose,body weight and adrenal gland weight/body weight(AW/BW)were determined in the 4 groups 12 weeks later;malondialdehyde(MDA)was examined with visible spectrophotometry;blood total cholesterol(TC)and triglyceride(TG)were examined with enzymology method;blood corticotrophin-releasing hormone(CRH),adreno-corticotrophic hormone(ACTH)and corticosterone(CORT)were examined with radioimmune method.Results:Blood glucose,MDA,TC,TG,CRH,ACTH,CORT and AW/BW in DM group were significantly higher than those in NC group(P

Objective To Explore the effect of Cassia Seed budding transforming organic vanadium. Methods Separate organic vanadium from inorganic vanadium in Cassia Seed sprouts by dislysis bag. The content of total vanadium and inorganic vanadium were determined by using the method of Graphite Atomic Absorption Spectrophotometry. The transformation efficiency of organic vanadium in the Cassia Seed spouts was calculated. Results The seed coat of Cassia Seed could accumulate massive inorganic vanadium existing in environment during the process of its natural growing period,but the transformation efficiency of organic vanadium mainly occurred inside seed coat of Cassia Seed. Condusion Cassia Seed budding is one pathway of the biologic organification of vanadium.

Objective To screen proteins binding with interferon?(IFN?)from human hepatic cDNA libraty by yeast-two hybrid technique.Methods The IFN?gene was amplified by polymerase chain reaction(PCR)and constructed into pGBKT7 vector as the bait plasmid in yeast-two hybrid system3,pGBKT7-IFN?was then transfected into yeast AH109.The transfected yeast were mated with yeast Y187 containing liver cDNA library plasmid in 2?YPDA medium.Diploid yeast was plated on synthetic dropout nutrient medium(SD/-Trp Leu-His-Ade)and synthetic dropout nutrient medium(SD/-Trp-Leu-His-Ade)containing X-?-gal for selecting.After plasmid extracting and en- zyme cutting analysis,the blue colonies were performed sequence analysis,the results were analyzed by bioinformatics.Results IFN?gene was successfully cloned and expressed in yeast cells.Thirty- four positive colonies were obtained using yeast-two hybrid technique.After sequence analysis,eight clones were found may have a binding effect with IFN protein.Conclusions IFN?genes was success- ful cloned and eight proteins that could bind with IFN?protein were also screened.

Objective To evaluate the effectiveness of biofeedback for anxiety patients by carrying out a Meta-analysis.Methods We searched CNKI,VIP,CBM(1989 to 2013) to identify relevant randomized-control trials applying biofeedback for anxiety patients.We used Review Management (RevMan) 5.0 software (provided by the Cochrane collaboration) to conduct Meta-analysis.Results We included 11 studies.Meta-analysis for the biofeedback group vs.the control group showed that biofeedback was significantly superior to control (SMD=-3.00,95％CI:-4.40～-1.61); Meta-analysis for the biofeedback plus drug group vs.drug group showed that biofeedback plus drug was significantly superior to drug (SMD=-1.33,95％CI:-1.82～-0.85).Conclusions We found evidence that biofeedback (applying alone or combined with drugs) is effective in improving anxiety symptom.But all the studies had methodological limitations,our conclusion needs further studies with strict design,high quality and consistent assessment tools to be expounded and proven.

Objective To objectively evaluate the effectiveness of reminder system in reducing catheter-associated urinary tract infections.Methods Databases were electronically searched to collect the trials.According to the inclusion and exclusion criteria,the literatures were screened,the data were extracted and the methodological quality of the included studies was assessed.Then Meta-analysis was performed by using RevMan 5.0 software.Results A total of 10 literatures involving 5 662 participants were included.The results of Meta-analysis showed that the reminder system group was superior to the control group in decreasing the incidence rate of catheter-associated urinary tract infections,shortening the days of indwelling catheter,and there were statistical differences.Conclusions Reminder system can shorten the days of indwelling catheter,decrease catheter-associated urinary tract infections,

AIM: To establish a determination for ephedrine hydrochloride and pseudoephedrine hydrochloride in Suxing Capsules(Herba Ephedrae, Semen Armeniacae Amarum, Fructus Perillal, etc.). METHODS:HPLC with Agilent ZORBAX Extend C_(18) (250 mm?4.6 mm, 5 ?m) column was used. Acetonitrile-0.2% H_3PO_4(5∶95) was used as a mobile phase. The flow rate was 1.0 mL?min~(-1). The detection wawelength was at 210 nm. RESULTS:The methodological evaluation showed that this method had a good repeatability and reproducibility; The average recovery of ephedrine hydrochloride was 99.65% and RSD was 1.6%. The average recovery of (pseudoephedr)ine hydrochloride was 98.90% and RSD was 2.3%. CONCLUSION: This method is simple, quick, accurate and with good reproducibility and can be used for the quality control of Suxing Capsules.

Objective To investigate the effects of eye movement desensitization and reprocessing (EMDR) versus cognitive behavior therapy (CBT) for treating adult posttraumatic stress disorder (PTSD) .Methods A total of 81 patients with PTSD con‐forming to the including standard were randomly allocated to the EMDR group ,CBT group ,and control group ,27 cases per group . The PTSD symptoms ,anxiety and depression moods in 3 groups were assessed before and after treatment by adopting the Clinician‐administered PTSD Scale (CAPS) ,Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) .Results The drop‐out rates were 29 .63% for the EMDR group ,7 .41% for the CBT group and 7 .41% for the control group respectively ;the re‐experience symptoms score of CAPS in the EMDR group was lower than that in the CBT group with statistical difference (P=0 . 036) .Conclusion Both EMDR and CBT are the effective psychological therapeutic method ,EMDR has more effective than CBT in the reproving the re‐experience symptoms of PTSD .The future studies should pay more attention to the application of stabilization technologies for reducing the dropout rate of EMDR .
