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 Acute renal failure (ARF) requiring renal replacement therapy (RRT) was reported in 0.33％to 9.5％ patients after cardiac surgery.This study was designed to assess the clinical usefulness and accuracy of 3 clinical tools for the prediction of ARF after cardiac surgery in Chinese patients.Methods Five hundred and four eligible patients with complete clinical data in our institution received prospective assessment for RRT and acute kidney injury (AKI) between June,2009 and November,2010.The clinical tools used were Cleveland ARF Score,acute kidney injury prediction following elective cardiac surgery(AKICS) and Simplified Renal Index(SRI).Hosmer—Lemeshow goodness-of-fit test was used to estimate the calibration.Discrimination was determined with receiver operating characteristic (ROC) curves and area under a ROC curve (AUC).Results Follow-up was completed in all 504 patients.The overall incidence of postoperative RRT was 3.17％(16/504) with a mortality of 37.5％,and the incidence of AKI was 5.36％ ( 27/504 ).Discrimination for the prediction of RRT and AKI was good for SRI measured with AUROCs:0.759 (95％ CI,0.643-0.874) for RRT and 0.773 (95％ CI,0.677-0.868 ) for AKI.SRI score performed better in terms of discrimination than Cleveland ARF score and AKICS in our study,which did not consist with results reported by other centers.Conclusion SRI scoring system is the most useful among three tools for predicting postoperative RRT and should be the first choice in Chinese patients for whom a cardiac surgery is planned.It can also be used in predicting the composite end point of AKI with an extended application in patients at risk for postoperative kidney dysfunction.

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 observe the clinical efficacy of sinew-bone balancing manipulation in treating lumbar disc herniation (LDH) and offer clinical evidence to support the concept of paying equal attention to sinew and bone. Methods: Sixty LDH patients were randomized into an observation group and a control group, with 30 cases in each group. The observation group was treated with the sinew-bone balancing manipulation, and the control group received conventional Tuina (Chinese therapeutic massage) manipulation. The clinical efficacy and posterior muscle chain tone effect were compared between the two groups by observing the visual analog scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and posture-associated indicators. Results: The total effective rate was 86.7％ in the observation group, higher than 76.7％ in the control group, but the between-group difference in efficacy was statistically insignificant (P>0.05). After treatment, the VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry showed significant changes in both groups (P<0.05). The VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry in the observation group were significantly different from those in the control group after treatment (P<0.05), but the between-group difference in the general posture symmetry was statistically insignificant (P>0.05). Conclusion: Both the sinew-bone balancing and conventional Tuina manipulations can reduce pain in LDH patients, improve lumbar function, and adjust the angle-dependent muscle tone coefficient of the posterior muscle chain and lumbar posture symmetry; except for the general posture symmetry of the posterior muscle chain, the sinew-bone balancing manipulation wins out over the conventional Tuina manipulation.
