OBJECTIVE:To establish the UPLC fingerprint for Qinghou liyan granule,and provide reference for its quality control by combining with principal component analysis (PCA). METHODS:UPLC was performed on the column of ACQUITY UPLC BEH C18 with mobile phase of acetonitrile(A)-0.1% aqueous phosphoric acid solution(B)(gradient elution)at a flow rate of 0.4 mL/min,the detection wavelength was 280 nm,column temperature was 30℃,and injection volume was 2μL. Using ellag-ic acid as a reference,12 batches of samples were analyzed,Similarity Evaluation Software for Chromatographic Fingerprint of Traditional Chinese Medicinewas used for the similarity analysis and identification of the common peaks,and the PCA was used for common peaks. RESULTS:There were 18 common peaks in the fingerprints of 12 batches of samples,and 6 principal peaks (gallic acid,ellagic acid,naringin,hesperidin,neohesperidin and baicalin) were identified;the similarity degree of 12 batches and reference fingerprints were no less than 0.984. According to PCA,the 18 peaks can be integrated into 3 principal components, with cumulative contribution rate of principal component of 78.277%;baicalin and 16 peaks were the discriminating factors of the fingerprint of Qinghou liyan granule. CONCLUSIONS:The method can provide reference for the quality control of Qinghou liyangranule.

Objective To explore the clinical characteristics and diagnosis of primary small intestinal tumor(PSIT). Methods Retrospective analysis of the clinical and pathological data of the 31 PSIT cases was made. Results Duodenum was the most common site 67.74% for PSIT. The confirmed diagnosis rate was 54.84%(17/31)(duodenum was 66.67%,14/21; ileum and jejunum was 30%, 3/10, respectively ). 3 cases were benign tumors and 28 were malignant tumors.The adenocarcinoma was the most frequently seen malignant PSIT followed by lymphoma and often in duodenal. The features of the small intestinal tumor could be abdominal pain,abdominal mass,hemorrhage,obstruction,jaundice and fever.The chief method for diagnose was barium meal X-ray examination, especially with the hypotonic contrast X-ray examination and endoscopy.Superior mesenteric arteriography sometimes helped in determing site of gastrointestinal haemorrhage. CT scan could be helpful in diagnosis. Conclusion Duodenal adenocarcinoma is most common PSIT,followed by malignant lymphoma.Endoscopy is the best way to find out the tumor located in duodenum and hypotonic contrast X-ray examination is effective in diagnosis and locating of small bowl tumors.Superior mesenteric arteriography is a good way to find out angioma and leiomyoma. CT scanning are also helpful.

Objective To explore the effect of benazepril combined with amoldipin on cardiac function and urine microalbuminuria in patients with moderate and severe primary hypertensive left ventricular hypertrophy.Methods 90 patients with mild to moderate essential hypertension and left ventficular hypertrophy were randomly divided into three groups(n=30 in each group),who were treated with benazepril,amoldinpin and benazepril com-bined with amoldipin,respectively.Blood pressure was monitored and left ventricular diameter(LVDd),interven-tricular septal thick(IVS),left ventricular posterior wall(LVPW),left ventricular masses index(LVMI)were measured by echocardiography before and after treatment in three groups.Microalbuminuria,serum nitrogen and creatinine were examined at the same time.Results Both SBP and DSP were significantly decreased in three groups after two weeks treatment.E/A ratio and EF were increased at the same time(P<0.01).After treatment,these changes were more significant in Benazepril with Amlodipine group(P<0.05).After 24 week treatment IVS,LVPW and LVMI were significantly dereased(P<0.01),while LVEF and E/A increased(P<0.01).After 4-week treatment,microalbuminuria was decreased in three groups,especially in combined treatment group(P<0.01).With the time of medication in combined treatment group,microalbuminuria was increasingly decreased which was significant in benazepril and amoldipin group after 24 weeks(P<0.01).Conclusion The Benzazepril with am-lodipine are more effective in lowering blood pressure,left ventricular hypertrophy and decrease microalbuminuria.

BACKGROUND: Transplantation of bone marrow mesenchymal stem cells (MSCs) improves functional recovery after spinal cord injury (SCl), but the mechanisms involved remain unclear.OBJECTIVE: To observe the effects of MSCs transplantation on the expression of brain-derived neurotrophic factors (BDNF) in rats after SCl.DESIGN, TIME AND SETTING: Randomized, controlled, animal experiment. The study was performed at the Laboratory of Neuroanatomy, China Medical University from April to July 2003.MATERIALS: A total of 64 SD rats, aged 3 months, of either gender, weighing 250-300 g, were used. Of them, 4 were randomly selected to isolate and culture MSCs, and the remaining were used to establish SCl models.METHODS: The 60 rats were randomly divided into 3 groups. Seven days after SCl, MSCs group (n=24) was transplanted with 5 μL culture solution containing 1×109/L MSCs to the injury site using micro-injection; PBS group (n=24) was transplanted with 5μ L PBS, and the blank control group (n=12) with 5μ L normal saline.MAIN OUTCOME MEASURES: The rats were sacrificed at 7, 14, and 28 days post-surgery. MSCs morphology was observed and the expression of BDNF at the lesion areas was examined by immunohistochemistry,RESULTS: All 60 rats were included in the final analysis. After ten subcultures, the cell proliferative capacity was reduced, and cell body turned to flat; the MSCs protiferation and morphous could be maintained by adding basic fibroblast growth factor.Transplantation of MSCs enhanced the expression of BDNF compared with PBS and blank control groups at 7, 14, and 28 days post-surgery (P ＜ 0.05); white no significant difference was found between PBS and blank control groups (P ＞ 0.05).

Objective To assess the efficacy and safety of propofol sedation for gastrointestinal endoscopy,we conducted a Meta-analysis of randomized controlled trials (RCT) comparing propofol with traditional sedative agents.Methods Referring Cochrane Collaboration search strategy to develop retrieval in Medline,Web of Science,Wanfang and CNKI database to retrieve the anesthetic propofol and traditional agents in the literature for randomized controlled trials of gastrointestinal endoscopy,surgery and assess their recovery effect.Results Twenty-one original RCTs investigating a total of 1 765 patients,of whom 894 received propofol only and 871 received traditional sedative agents only,met the inclusion criteria.Research showed that compared with traditional anesthetics,no significant differences existed in anesthetic effects of propofol on gastrointestinal endoscopy surgery time.However,surgery can significantly shorten recovery time and the average discharge time; and higher recovery rates.The result of racial subgroup analysis showed:the anesthetic propofol can significantly shorten the time of gastrointestinal endoscopy surgery for Asian populations,but had little effect on the European population.Contrast method for subgroup analysis showed:anesthetic propofol could significantly shorten the ERCP angiography in gastrointestinal endoscopy surgery time,but has little effect on the UGE and colonscopy angiography.Conclusions Propofol is safe and effective for gastrointestinal endoscopy procedures and is associated with shorter endoscopy recovery and discharge time,higher post-anesthesia recovery scores.Care should be taken when extrapolating our results to specific practice settings and high-risk patient subgroups.

Melanoma is the most aggressive and lethal malignant tumor in skin cancers. Operation resection is used to treat stageⅠ/Ⅱmelanomas, but traditional operation, chemotherapy, and radiotherapy inflicts adverse effects on late-stage melanomas. StageⅢ/Ⅳmelanomas are some of the most ineffectively treated tumors with poor prognosis. As a cancer treatment, targeted immunotherapy in-hibits negative regulatory factors and enhances systemic anti-tumor immune effects. Radiotherapy not only kills tumor cells, but also en-hances systemic immune responses. Recent studies showed that targeted immunotherapy combined with radiotherapy can promote con-trol on local and distant tumors and prolong overall survival. The synergistic effects of these two therapies are superior to a single thera-py. This review summarized the progress on these research fields.
