As one of the gastrointestinal malignancies,pancreatic cancer is well known because of high degree of malignancy,low survival rate and very poor prognosis.Lymphatic metastasis,the most important metastasis of pancreatic cancer,has the characteristics of metastasis in an early stage and high occurrence rate.Recently,some studies have suggested that widespread micrometastasis of lymph nodes occurring in the early stage of pancreatic cancer could play an important role in influencing postoperative neoplasm recurrence.Further studies on lymph node micrometastasis of pancreatic cancer are needed to help to understand pancreatic cancer more deeply and to comprehend metastasis rule more clearly.So we can choose more reasonable surgical treatment for every patient,achieving individual treatment,so as to improve the prognosis of the pancreatic cancer patients.

Objective To study the current status of morning blood pressure peak in elderly masked hypertension patients and study the correlation between morning blood pressure peak and cognitive function.Methods A total of 72 elderly masked hypertension patients were selected in this study,.Morning blood pressure peak was measured by ABPM examination.The patients were divided into three groups according to the morning blood pressure peak.Morning blood pressure peak ≤ 30 mmHg were divided into non-Morning blood pressure surge group ( NMS group),morning blood pressure peak ＞30 mmHg were divided into Morning blood pressure surge group ( MS group).The cognitive function scale was determined (MMSE and MoCA).T-test and linear regression analysis were performed.Results MMSE score(27.69±2.04) and MoCA scores(24.85 ± 1.52) in MS group were lower than NMS group (28.87 ± 1.34,26.54± 1.53) ( P ＜0.01 ).MMSE and MoCA scores were negatively correlated with the morning blood pressure peak ( r =- 0.308,- 0.447,P ＜ 0.01 ).Conclusions Elderly masked hypertension patients remained the phenomenon of the morning blood pressure peak,the morning blood pressure peak could lead to cognitive impairment.

Objective To evaluate the prevalence of aspirin resistance in old-aged patients with cerebral infarction and to analyze the mechanisms and clinical predictors of aspirin resistance. Methods 300 old-aged patients with cerebra] infarction were selected and the platelet aggregation ratio was determined by nephelometry with CHRONO-LOG PA-meter. And some information of these patients, such as age, sex, smoking, taking non-steroid anti-inflammatory drug (NSAD)or proton pump inhibitor (PPI), obesity, coronary artery disease (CAD), peripheral vascular disease, hyperpiesia, diabetes and hyperlipemia were recorded. Results 112 cases (37.33%) were aspirin sensitiveness, 108 cases(36.0%) were aspirin semi-resistance and 80 cases (26.67%) were aspirin resistance. These cases were divided into two groups. One was aspirin sensitive (AS) group, which included 112 patients of aspirin sensitiveness. The other was aspirin resistant (AR) group, which consisted of 188 patients of aspirin semi-resistance and aspirin resistance. The prevalence of CAD, hypercho]esteremia and RBC count in AR group was higher than that in AS group The percentage of patients who took NSAD, PPI and smoke in AR group was also higher than that in AS group. Conclusion Aspirin resistance existed in old-aged patients with cerebral infarction to great extent, and which was correlated with CAD, hypercholesteremia, smoking, RBC count, taking NSAD and PPI.

OBJECTIVE:To control the drug quality risk in drug withdrawal links of hospital pharmacy,and provide reference for the application of quality risk management(QRM)in hospital pharmacy. METHODS:Drug QRM was developed in drug with-drawal links through risk identification,risk assessment,risk control,risk assessment and other steps. Using the incidence of risk factors and reusable rate of withdrawal drug as indexes,related data of before(Jul.-Dec. 2015)and after(Jan.-Jun. 2016)devel-oping QRM in our hospital were compared to evaluate the effect of drug QRM. RESULTS:Determining whether specific storage drugs kept the required storage conditions,whether the numbers of withdrawal drugs counted to minimal packaging and other 5 fac-tors were high-risk factors(the risk score of each factor>4 points);control measures were taken separately for high risk factors, then high-risk factors were reduced to acceptable levels(risk score<4 points). After developing QRM,the incidence of risk factors were reduced than before(reduce 1.35%-6.19%),reusable rate of withdrawal drug was increased(98.64% vs. 86.32%)(all P<0.05). CONCLUSIONS:Developing QRM in drug withdrawal links of hospital pharmacy can reduce the drug quality risk.

To inquire into the influence on effect, safety and receiving rate of thrombolysis in acute myocardial infarction (AMI) after extending its selective indications. We observed the main indication changes and effect of 201 cases of AMI receiving thrombolytic therapy who from 108 patients with AMI. Results: (1)On basis of the thrombolytic scheme recommended by the committee of Chinese Journal of Cardiology in 1991,further extend the time of onset to medication from ≤6 hr. to ≤12 hour,age from ≤65 yr,to all yr, unlimited. The ratio of cases receiving thrombolysis/all AMI is 49. 3%, more than before extending indications (28. 1% ,P0. 05) between group 6- 12 hr,medication (n- 32) and ≤6 hr's (n= 169) ,but its mortality in both groups above is significantly lower than group non-thrombolysis (18. 4%,both P

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 observe the influence of blood-nourishing and wind-expelling therapy on the therapeutic effect of epidermic grafting for vitiligo. [Methods] Sixty-two patients with vitiligo were allocated to group A (n = 32) and group B (n = 30) with simple random method. Group B was treated with epidermic grafting. Group A was treated with oral use of Baibofeng Decoction (mainly composed of Radix Angelicae Sinensis, Caulis Spatholobi, Radix Saposhnikoviae, Fructus Psoraleae, Radix Paeoniae Rubra , Radix Salviae Miltiorrhizae, etc.) 2 weeks after epidermic grafting was performed, one dose every other day, and with external application of Fubu tincture (composed of Fructus Psoraleae, Radix Angelicae Dahuricae, Radix Salviae Miltiorrhizae and Flos Carthami) bid. After treatment, the short-term and long-term therapeutic effect was observed in the two groups. [Results] The cure rate was 83.6% and the effective rate was 93.1% in group A, and respectively 71.0% and 88.5% in group B, the therapeutic effect of group A being better than that of group B (P

Objective To evaluate the effect of transarterial chemoembolization (TACE) before operation, including side effects and the improvment for the suceesfult resection rate.Methods 56 patients with cardiac cancer were divided into two groups: TACE group and resection group. The former included 25 patients (male 14, female 11) undertaken TACE 7-15 days before surgery. The image manifestations, histological changes and side effects together with the time of operation, volume of blood lose during operation and the succesful resection rate were compared with those of the latter. Results 1. TACE induced the necrosis of tumor tissue to some extent and possessed the power to localize the lesion with little side effects. 2. TACE before resection did not only minimize the injury of operation but also improved the resection rate. Conclusion TACE is a safe, effective modality before operation and is worthy for recommendation
