Objective] To observe the influence of YIGU oral liquid on the pain threshold and bone mineral density in ovariectomized rats. [Methods] Eighty-four Female SD rats were randomly divided into 4groups:YIGU oral liquid group, calcitonin group,YIGU oral liquid combined with calcitonin group, saline control group.The ovariectomized rats were confirmed the successful model of osteoporosis,rats in the YIGU oral liquid group were administered with YIGU oral liquid, rats in the calcitonin group were administered with calcitonin, rats in the YIGU oral liquid combined with calcitonin group were administered with YIGU oral liquid group and calcitonin,rats in the saline control group were administered with saline.To detect the pain threshold and bone mineral density at the 10th day, 30th day, 60th day and 90th day respectively. [Results]At the 10th, 30th, 60th and 90th day after treatment, the pain threshold of the YIGU oral liquid group, calcitonin group,YIGU oral liquid combined with calcitonin group compare to saline control group, there was significant statistical difference( P<0.05).At the 10th, 30th day after treatment,the bone mineral density of the YIGU oral liquid group, cal-citonin group,YIGU oral liquid combined with calcitonin group compared with saline control group, there was no significant statistical difference( P>0.05). At the 60th,90th day after treatment, there was significant statistical difference( P<0.05).[Conclusion] YIGU oral liquid can effectively enhance pain thresh-old and bone mineral density of the ovariectomized rats to inhibit the osteoporosis pain.

Background and purpose:Fumagillin is an inhibitor of type 2 methionine aminopeptidase that can block blood vessel formation. However, its molecular mechanism and therapeutic value in colon cancer still remain to be elucidated.In this study, the effect of Fumagillin on the growth of colon cancer was examined. Methods:Twenty mice were divided into 4 groups and injected subcutaneously with 5?105/L WiDr or HT-29 cells in 200 ?L phosphate-buffered saline (PBS) respectively. After 4 weeks, intraperitoneal injections of Fumagillin (0.1 mg/kg), Cyclo (1 mg/kg), or both were given every 2 days for 4 weeks. The tumor weight and microvessel density (MVD) were examined. Geneexpression profiles were examined by microarray analysis of human umbilical endothelial cells (HUVECs). Results: The Fumagillin-treated mice showed smaller tumor mass and lower MVD-CD105 levels than control ones. In vitro proliferation and tube formation of HUVEC was also significantly decreased by Fumagillin. Microarray analysis of Fumagillin-treated HUVECs showed up-regulation of 71 genes and down-regulation of 143 genes. Expression changes were involved in cell proliferation, migration, adhesion and gene transcription. Quantitative real time-polymerase chain reaction and Western blot revealed decreased expression of cyclin E2, activated leukocyte cell adhesion molecule (ALCAM), and intercellular adhesion molecule-1 (ICAM-1) genes in the presence of Fumagillin. Conclusion: Fumagillin was found to suppress colorectal cancer growth by suppressing angiogenesis. The down-regulation of cyclin E2, ALCAM and ICAM-1 by fumagillin may be involved in the anti-angiogenesis.

Objective To establish HPLC fingerprint for evaluating and controlling the quality of Gastrodia elata. Methods HPLC Analysis and similarity calculation were used for establishing fingerprint chromatogram and classifying 18 different original samples; LC-MS and pure compound comparisons were employed for the fingerprint peaks identification. Results HPLC Fingerprint chromatogram was cons- tructed with 27 fingerprint peaks, 17 of which were common fingerpring peaks and 12 main compounds were identified. According to the similarity to standardize herbal medicine, 18 samples could be classified three groups, Anhui-Henan, Shanxi-Sichuan, and Yunnan habitats. The two critical points were 0.80 and 0.58 for correlation coefficient and 0.88 and 0.73 for cosine values. Conclusion The selected fingerprint peaks are diagnostic for G. elata and the constituted HPLC fingerprint chromatogram could be used for identifying different habitats and served as a powerful tool for further quality control of G. elata.

In this study, a novel tetrapeptide hydrophilic interaction chromatography (HILIC) material was synthesized, and corresponding enrichment method for glycopeptides was developed.The tetrapeptide modified silica gel materials (denoted as Poly-DAPD) were synthesized by atom-transfer radical-polymerization (ATRP) and characterized by N2 adsorption desorption and thermometer, thermal gravimetric analyzer (TGA) and X-ray photoelectron spectrometer (XPS).The characterization results indicated that tetrapeptide had been successfully synthesized on silica gel.Poly-DAPD materials showed high enrichment selectivity toward fetuin glycopeptides under solid-phase extraction (SPE) mode.Comparing with commercialized ZIC-HILIC in glycopeptides enrichment of fetuin digest which mixed with 5 mole ratio of albumin bovine (BSA), the as-prepared materials showed higher selectivity in both aspects of the identified number of glycopeptides and anti-interference property.The SPE results demonstrated that the tetrapeptide-based HILIC materials could be a potential tool in large-scale glycosylation analysis.

Objective To evaluate the feasibility and safety of a delivery pathway for the performance of percutaneous left atrial appendage (LAA) occlusion in experimental canine models. Methods Transseptal puncture was performed via femoral vein approach under fluoroscopic and angiographic guidance in 12 experimental dogs. A pigtail catheter was advanced into the left atrium (LA), which was followed by LA angiography. The diameters of the neck of LAA were measured on LAA angiogram obtained in appropriate projection. After the delivery sheath was advanced along the wire into LA, a pigtail catheter was inserted into the ostium of the LAA and the sheath was then advanced over the pigtail into the LAA. LAA angiography was then performed through the delivery sheath to confirm the position of the delivery sheath. One hour after the procedure both electrocardiography (ECG) and transthoracic echocardiography (TTE) were carried out in five dogs to check the results, immediately after which the five dogs were sacrificed to macroscopically observe the damages of the puncture site of inter-atrial septum as well as inside the LA and LAA. One hour and 2 weeks after the procedure TTE was conducted in the remaining 7 dogs and these dogs were followed up for one month. Results One dog died of pericardial tamponade during the operation. In 8 dogs the LAA was clearly displayed in the projection position of right anterior oblique (RAO) 30°/cranial (CRA) 20°,while in 3 dogs the LAA was well visualized in the projection position of RAO 30° , and in one dog in the projection position of RAO 30°/caudal (CAU) 20°. The diameter of LAA neck was (13.6 ± 5.2) mm. The delivery sheath was safely advanced into the LAA along the pigtail catheter in all dogs, and no air embolism, thrombus or pericardial tamponade occurred. Hematoma at puncture point of groin occurred in 2 dogs, which was absorbed through pressure dressing. Macroscopic examination of the heart performed immediately after the operation showed that no bloody pericardial effusion was found, and mild hematoma at posterior wall of LA was seen in one dog and mild damage of the upper-margin intima of LAA was noted in 2 dogs. The mean fluoroscopy time was (10.1 ± 2.5) minutes and the mean operation time was (58 ± 12) minutes. TEE showed no pericardial effusion 2 weeks after the procedure. During the follow-up period of one month no sudden death, stroke or infection occurred. Conclusion This method of placing the delivery sheath into the LAA is clinically safe and effective, and it can reliably establish a pathway to advance the LAA occluder into LAA.
