Isolation of high-quality genomic DNA from dried and processed crude drug is the key for the DNA identification of Dendrobii Caulis. The DNA extract of Dendrobii Caulis was firstly compared using different method to isolate genomic DNA from dried and processed crude drug, including commercial DNA extracted kit and CTAB method. Using modified CTAB method (extracted from large samples), the genomic DNA was successfully isolated from Dendrobii Caulis, including Huangcao and Fengdou. The ITS regions were amplified using the purified DNA as template, and then cloned and sequenced. These ITS sequences were compared with data from Genbank database and our lab, 14 Dendrobium species and five similar species were identified from "Huangcao" and "Huangcao" slice, while six species and three similar species from "Fengdou" according to their sequence similarity. The study demonstrated that the dried Dendrobii Caulis could be identified using DNA molecular method, which could overcome deficiencies and limitations of traditional identification method and has a certain application prospects.

OBJECTIVE: To investigate the antibiotic use in Shanghai Second and Third Class Hospitals. METHODS: The use of antibiotics in outpatients and inpatients in 10 third class hospitals and 13 second class hospitals were analyzed statistically in respect of consumption sum, order of varieties. RESULTS: The proportion of antibiotic use in Shanghai second and third class hospitals showed a different degree of decrease. However, in terms of the number of prescriptions and consumption sum, the proportions of antibiotics used in outpatient department were significantly higher in second class hospitals than in third class hospitals. The proportion of antibiotic use in inpatients (both non-surgery and surgery ones) were still on the high side, most had a postoperative antibiotic using coure of 3 to 7 days. CONCLUSION: The proportion and duration of antibiotic use should be strictly under control to ensure safe, effective and economical use of antibiotics.

The identity of higher-order neurons and circuits playing an associative role to control renal function is notwell understood.We identified specific neural populations of rostral elements of brain regions that project multisynaptically to the kidneys in 3~ days after injecting a retrograde tracer pseudorabies virus (PRV)-614 into kidney of 13 adult male C57BL/6J strain mice.PRV-614 infected neurons were detected in a number of mesencephalic (e.g.central amygdala nucleus),telencephalic regions and motor cortex.These divisions included the preoptic area (POA),dorsomedial hypothalamus (DMH),lateral hypothalamus,arcuate nucleus (Arc),suprachiasmatic nucleus (SCN),periventricular hypothalamus (PeH),and rostral and caudal subdivision of the paraventricular nucleus of the hypothalamus (PVN).PRV-614/Tyrosine hydroxylase (TH) double-labeled cells were found within DMH,Arc,SCN,PeH,PVN,the anterodorsal and medial POA.A subset of neurons in PVN that participated in regulating sympathetic outflow to kidney was catecholaminergic or serotonergic.PRV-614 infected neurons within the PVN also contained arginine vasopressin or oxytocin.These data demonstrate the rostral elements of brain innervate the kidney by the neuroanatomical circuitry.

OBJECTIVE:To study the econamics effect of risperidone and quetiapine in treating of schizophrenia.METH ODS:64schizophrenia patients were randomly divided into risperidone group(34cases)and quetiapine group(30cases).The effects were evaluated based on the reduction of scores determined by brief psychiatric rating scale(BPRS);the adverse effects were evaluated by treatment emergent symptom scale(TESS).And then the cost-effectiveness analysis was carried through.RESULTS:The per capita costs for risperidone and quetiapine were3598.85yuan and3778.63yuan respectively;the re-duction of BPRS scores were(36.09?15.52)and(25.03?14.45)respectvely;the respective cost-effect ratio was99.72yuan and150.96yuan;the increment of the cost-effect ratio for the quetiapine group was-16.25compared with the risperidone group.CONCLUSION:Risperidone is more economical than quetiapine in the treatment of schizophrenia.

OBJECTIVE:To analyze the cost-effectiveness of3kinds of Chinese patent drugs in the treatment of insomnia outpatients.METHODS:78outpatients with insomnia were randomly divided into group A,group B and group C,and they were treated with shumian capsule,sweet dream capsule and compound semen ziziphi spinosae capsule,respectively,then,cost-effectiveness analysis was carried out with pharmacoeconomics.RESULTS:The per capita costs(C)for group A,B and C were288.20yuan,163.08yuan and139.22yuan respectively,the reduction in PSQI scores(E 1 )were5.15,8.88and11.84respectively,the effective rates(E 2 )were26%,46%,and64%respectively;The average cost-effect ratios C/E 1 were55.96,18.36,and11.76respectively;C/E 2 were11.08,3.55,and2.18respectively;The increment of the cost-effect ratios?C/?E 1 for group A and B were—22.27and—8.06respectively;?C/?E 2 were—3.92,—1.33respectively,as compared with group C.CONCLUSION:Compound semen ziziphi spinosae capsule is more economical in3drugs in treating insomnia outpatients.

OBJECTIVE To provide the clinical anatomy data of the lingual artery for clinical application concerning about the lingual artery. METHODS CTA examination of the carotid artery was performed in 80 adult volunteers. The 3D reconstruction images of the carotid artery with hyoid bone were obtained by using 64-slices spiral CT. At the same time, 20 extraoral dissections of the submandibular region were performed on 10 human cadavers. The origin, pathway, and anatomic relations of the lingual artery in CTA and cadavers were studied. The distance from the origin of the lingual artery to the bifurcation of the common carotid artery and tip of the greater horn of hyoid bone were separately measured, and the distance between the segment of the greater horn of hyoid bone of lingual artery and the middle of greater horn of hyoid bone were also measured. And the contrast analysis was carried on the result. RESULTS The lingual artery was mainly come from the external carotid artery (74.4 % in the CTA; 80% in the Cadavers), the next origin was come from the facial artery (23.1 % in the CTA; 20 % in the Cadavers), and it was few to found that the lingual artery had origin in the superior thyroid artery, which was 2.5 % in CTA and none in Cadavers. The path of the lingual artery had high variation, but the position between the segment of the greater horn of hyoid bone of lingual artery and the greater horn of hyoid bone had constancy relatively. The lingual artery run forward with approximation parallel to the greater horn of hyoid bone into tongue,and which located in thesuperior to the greater horn of hyoid bone (2.32?1.29 mm) or in the inferior to the greater horn of hyoid bone (2.00?1.68 mm). The distances from the origin of the lingual artery to the bifurcation of the common carotid artery and tip of the greater horn of hyoid bone in CTA and cadavers were (12.93?7.36) mm, (10.40?5.75) mmand (14.80?6.18) mm, (8.35?5.44) mm respectively. CONCLUSION The lingual artery can be show clearly in CTA and can get the anatomy data in physiological condition with CTA.

OBJECTIVE To assess the effect of Ibudilast on the quality of life (QOL) of patients with steroid resistant allergic rhinitis.METHODS A randomized,double-blind,placebo-controlled study was carried out with Ibudilast in 66 patients with the steroid resistant allergic rhinitis.QOL was measured with Short-Form Health Survey (SF-36) questionnaire (Chinese version).Ibudilast (10rag twice daily,34 patients),placebo (32 patients) was given for 3 weeks. The SF-36 questionnaire was administered at the start of treatment and after 3 weeks of treatment.Sings and Symptom-medication scores were measured daily during the study.RESULTS There were no significant differences between the Ibudilast and placebo group in terms of sings and symptoms or QOL scores before study.After 3 weeks of treatment,symptoms scores were significantly decreased and QOL scores significantly improved in the Ibudilast group compared with those in placebo group (both P
