OBJECTIVETo study the expression difference in MicroRNA-21 (miRNA-21) levels of the plasma between the patients with coronary heart disease and the subjects without coronary artery lesions, and its clinical significance.

METHODSPlasma was obtained from the patients with coronary heart disease(trial group,56 cases) and the subjects without coronary artery lesions(control group, 10 cases), patients with coronary disease were divided into angina(AP, 39 cases) and acute myocardial infarction(AMI, 17 cases)subgroup, the contents of miRNA-21 were detected using qRT-PCR method, and the differential expression of miRNA-21 in each group was analyzed. The levels of creatine kinase isoenzyme (CK-MB), high sensitive troponin I(cTnI), B type natriuretic peptide urea (BNP), Gensini, left ventricular ejection fraction (LVEF), integral value of coronary left ventricular end diastole diameter (LV) and homocysteine (HCY) were determined and the correlation between miRNA-21 and these clinical indexes was analyzed.

RESULTSCompared with control group, there was a significant difference in expression of miRNA-21 in patients with angina and AMI (P < 0.05), and miRNA-21 expression in AMI group was much higher than that in AP group. There was statistical significance in CK, CK-MB, cTnI, Genisis integral comparison between AMI group and control group (P < 0.05). The correlation analysis showed that there was a positive correlation between expression of CK, CK-MB, cTnI and the level of circulating miRNA-21 in patients with acute myocardial infarction. And there was a negative correlation between BNP, Gensini integral, LVEF value of coronary artery, LV and circulating miRNA-21.

CONCLUSIONmiRNA-21 was significantly elevated in acute myocardial infarction subgroup than the control group. The level of miRNA-21 associates with the degree of coronary artery stenosis, and might be a potential marker for the diagnosis of acute myocardial infarction. miRNA-21 may play an important role in protecting myocardium from ischemia/reperfusion injury.

Objective:To survey the enablement level of elderly patients in the community and its influencing factors.Methods:A total of 460 patients aged ≥60 years visiting Changfeng and Fenglin Community Health Service Centers of Shanghai during September 3 to 15, 2018 were invited for a questionnaire survey. A self-made health status questionnaire, Patient Enablement Instrument (PEI), Chinese Health Questionnaire (CHQ-12), the Consultation and Relational Empathy Measure (CARE) were applied for survey.Results:All valid 460 questionnaires were retrieved. The positive rate of patient enablement was 73.91% (340/460). The median score for PEI was 3, Q1 was 0 and Q3 was 6. The univariate analysis showed that patient′s gender( Z=-2.32, P=0.02), age ( H=9.73, P<0.01), reason for visit ( H=42.06, P<0.01), health status in the past year ( H=8.28, P=0.02), consultation time ( H=22.92, P<0.01), sufficiency of communication with the doctor as patient thought ( H=41.83, P<0.01), detailed inquisition ( H=81.11, P<0.01), attending a contracted doctor ( Z=-3.42, P=0.04), the satisfaction of the visit ( H=38.64, P<0.01), total score of CHQ-12 ( Z=-2.01, P=0.04) and the score of CARE were significantly associated with the enablement level of the patient after the visit ( H=288.06, P<0.01). Multivariate linear regression showed that age 60-79( P=0.03), visit for acute disease( P<0.01), good or moderate health status in past year ( P<0.01), communication with the doctor<3 min or 3-<5 min ( P<0.01), sufficient or moderate time for communication with the doctor as patient thought ( P<0.01), detailed or moderate inquisition( P=0.03 or P=0.01), attending a contracted doctor ( P<0.01), CHQ-12 ≥4 ( P<0.01), middle or high CARE score ( P<0.01)were associated with the enablement of elderly patients after visit, with a cumulative contribution rate of 73.40%( F=50.08, P<0.01). Conclusion:The level of enablement of elderly patients after visiting the general outpatient clinic of the community health service center is relatively low. Patient′s age, types of disease, health status and the time of communication with the doctor, the sufficiency of communication time as patient thought, the detailed inquisition, attending a contracted doctor, the mental health status, and the empathy expression of the doctor are associated with the enablement of patients.

Objective To unveil the current situation and bends of Keshan disease in Pingliang city of Gansu province, to evaluate the outcome of related prevention and control measures, and to provide scientific basis for further prevention and treatment of the disease. Methods According to the "the central allowance local public health special funds endemic disease prevention programs grams mountain monitoring programme" and "the diagnostic criteria for Keshan disease" (GB 17021-1997), between 2007 and 2009, local residents from nine monitoring points in Pingliang city of Gansu province were clinically examined, and electrocardiography(ECG) tracings and Xray were taken of suspected cases. Corn, wheat samples and hair samples of children, adults and women were collected, and selenium content of these samples was determined by 2.3-2-amino-naphthalene fluorescence method. Results A total of 5846 residents were surveyed in 3 years, 247 cases of Keshan patients were detected, with a detection rate of 4.23%(247/5846), of which potential cases of Keshan disease 214, the detection rate was 3.66% (214/5846); chronic Keshan disease 33 cases, the detection rate was 0.56% (33/5846); no acute type and subacute Keshan disease detected. A total of 764 abnormal ECG cases were detected, and abnormal detection rate was 13.07%(764/5846). Two hundred and seven cases of suspected patients were examined by chest X-ray, 80 cardiac enlargement cases were detected, the detection rate was 38.6% (80/207). The 262 hair samples of children, adults and women were analyzed, hair selenium was (0.279 ± 0.098)mg/kg. Of the 9 corn and 31 wheat samples collected, corn selenium was (0.0079 ± 0.0029)mg/kg; wheat selenium was (0.0104 ± 0.0078)mg/kg. Conclusions Overall Keshan disease is in a stable and subsided trend in Pingliang city of Gansu province, but there are still a number of potential chronic types, sporadic new cases, suggesting that the disease monitoring, comprehensive prevention and treatment of the patients are the focus.

In order to improve the teaching quality of epidemiology and better serve the situation of disease prevention and control,problem-based learning (PBL) teaching method was applied in the teaching of epidemiology. This paper introduced the implementation of PBL and its advantages and disad-vantages. PBL teaching method can improve students' self-learning ability,communication skills,team cooperation,practical ability and capability of integrating knowledge of many subjects.

Objective: Overexpression of the HER2/neu oncogene is a frequent molecular event in multiple human cancers. Being a cancer antigen, p185 erbB2 is an ideal target for immunotherapy. In order to decrease the immunogenicity of mouse anti-p185 erbB2 monoclonal antibody in human cancer therapy, we constructed the eukaryotic expression vector of anti-p185 erbB2 chimeric monoclonal antibody and verified expression of the chimeric antibody in CHO-dhfr - cell. Methods: The variable regions of light chain and heavy chain were amplified with RT-PCR and inserted into the chimeric antibody vector pWSD2. After CHO-dhfr - cells were transfected with recombination plasmid by lipofectAMINE, the chimeric antibody expressing level was identified with RT-PCR, indirect-ELISA, and Western blot. The specificity of the anti-p185 erbB2 chimeric antibody was testified with ELISA assay and immunoprecipitation. Moreover, the effects of chimeric antibody on the proliferation of breast cancer cell line SKBR3, which is overexpressing p185 erbB2 , were measured with MTT assay in vitro. Results: The anti-p185 erbB2 chimeric antibody eukaryotic expression vector was constructed successfully and the expression of the chimeric antibody in CHO-dhfr - was verified by RT-PCR, indirect-ELISA, and Western blot. ELISA assay showed that chimeric antibody reacted with cells overexpressing p185 erbB2 specifically, but did not react with that non-overexpressing p185 erbB2 . Immunoprecipitation test confirmed that the chimeric antibody could bind to p185 erbB2 specifically. The MTT assay demonstrated that the chimeric antibody could inhibit the growth of SKBR3 cells overexpressing p185 erbB2 . Conclusion: The anti-p185 erbB2 mouse/human chimeric antibody that was expressed in CHO-dhfr - cells can bind to p185 erbB2 specifically and inhibit proliferation of SKBR3 cells overexpressing p185 erbB2 . It has a potential application in biotherapy of cancer.
