Objective To use the flow cytometry to detect the platelet vasodilator-stimulated phosphoprotein(VASP)phospho-rylation level and to evaluate the clopidogrel curative effect after PCI.Methods 17 cases in the control group without any drug in-tervention and 26 cases of acute coronary syndrome(ACS)after PCI operation with clopidogrel were selected.Platelet VASP phos-phorylation levels at being selecting and on 7 d after anti-platelet therapy were detected by the flow cytometry and the platelet reac-tivity index (PRI)was calculated.Results The PRI after anti-platelet therapy in the ACS group was decreased significantly,the difference between before treatment and after treatment had statistical significance (P <0.05 ).Conclusion The platelet VASP phosphorylation level detected by the flow cytometry can specifically evaluate the effect of clopidogrel.

Pancreatic neuroendocrine tumors(pNETs)have a low prevalence,and may be func-tional as secreting biologically active substance or nonfunctional. With the increased understanding of this disease,new technologies are being developed for diagnosis and treatment. However,surgical excision re-mains the primary therapy for localized tumors and the cure rate is not ideal yet. In choosing the appropri-ate therapy for locally advanced/ metastatic pNETs,medical management strategy should be made in a multidisciplinary context. In addition to chemotherapy,there have been significant advances in targeted mo-lecular therapy.

A questionnaire and telephone survey was conducted on 246 patients with chronic liver diseases in the Outpatient Clinic from August 2010 to May 2011.The distribution of diseases and the causes of losing follow-up were analyzed. Most subjects in this survey (182/246,74.0％ ) were patients with chronic viral hepatitis( HBV or HCV)and cirrhosis; and their follow-up status was better than others (X2 =12.382,P ＜ 0.05). There were no differences in gender( X2 =10.137,P ＞ 0.05),but significant differences in age ( X2 =31.783,P ＜ 0.05 ) and educational levels ( X2 =32.803,P ＜ 0.05 ) between patients with chronic viral hepatitis and cirrhosis and patients with other liver diseases.The main causes of losing follow-up were neglect of disease by patients (38.3％) and lack of good communication between doctors and patients ( 18.3％ ).It is important to reinforce the understanding and awareness of chronic liver diseases for patients.

Objective:To survey the status of illness and consultation within two weeks among residents in a community in Chengdu.Methods:A multi-stage stratified random sampling was used to carry out a questionnaire survey among the residents in a community in Chengdu during March to April 2019. The disease status, disease severity and consultation within two weeks were surveyed, and influencing factors of two-week illness were analyzed with logistic regression.Results:Among 2 714 participants, 715 had illness (900 times) within two weeks, with a two-week prevalence rate of 26.3%. The main symptoms were dizziness (6.4%, 58/900), cough (6.2%, 56/900), lumbago and leg pain (4.9%, 44/900), palpitations (3.3%, 30/900) and headache (3.1%, 28/900). The three most common diseases were hypertension (38.3%, 345/900), diabetes (19.3%, 174/900) and common cold (6.4%, 58/900). In this survey, the rate of two-week in bed was 20.6‰(56/2 714), and the rate of two-week off work was 4.8‰(13/2 714). Age, gender, education level and work status were the influencing factors of the illness in two weeks ( P<0.05). The choice of medical institution was also different among residents. Conclusion:The survey suggest that primary care should focus on the key groups of residents in the community such as elderly, women, low education level, retirement and unemployed; and it is necessary to strengthen the primary care institutions and two-way referral system of health care.
