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 establish a assessment system for comprehensive clinical competency of general practice residents.Methods An assessment system for comprehensive clinical competency of general practice residents was developed with modified Delphi expert consultation during November 2010 to October 2011.Thirty three experts in clinical practice,education and administration of general practice were invited for two-round Delphi questionnaire consultation.Results In two-round consultation,the expert activity coefficient was 100％,the authority coefficient was 0.852 and 0.855,and the coordination coefficient for the importance of the indicators was 0.228 and 0.245 respectively (P =0.000).The opinions among the experts became consistent from round 1 to round 2.An assessment system was established,which consisted of 5 first-level (professionalism,communicate skills,clinical competency and professional development ability) and 36 second-level indicators.Conclusion The index system established in this study may be used as references for evaluating comprehensive clinical abilities of general practitioners systematically and objectively.

Objective To detect the expression of Cytokeratin 19 (CK19) mRNA in the peripheral blood of cervical carcinoma patients and evaluate its clinical significance.Methods The expression of CK19 mRNA was evaluated by fluorescent quantitative reverse transcription polymerase chain reaction ( FQRT-PCR ) in the peripheral blood of 138 patients with cervical carcinoma and 36 patients with benign gynecological tumors.In 138 patients,possible correlations between clinical pathological factors were analyzed.Results The positive expression rates of CK19 mRNA was 69.6％ in 138 cervical carcinomas in comparison with 13.9％ in benign gynecological tumors,and 57.9％ in patients with FIGO Stage Ⅰ A to Ⅱ A cervical carcinoma in comparison with 80.6％ in patients with FIGO Stage Ⅱb to Ⅳ cervical carcinoma.The expression of CK19 mRNA in patients with FIGO Stage Ⅰ A to Ⅱ A cervical carcinoma were significantly correlated with stage,differentiation and lymph vascular space involvement,but was not associated with prognostic factors including age,bully tumor size,pathological types,deep stromal invasion and lymph node metastasis.In multivariate survival analysis,lymph vascular space involvement was an independent risk factor of CK19mRNA expression in patients with cervical carcinoma.Conclusions Fluorescent quantitative RTPCR can be used to detect the expression of CK19 in the peripheral blood of cervical carcinoma patients,and it is a sensitive and specific technique.CK19 mRNA in peripheral blood may be a potential biomarker for detecting micrometastasis in cervical carcinoma.The results suggest a possible use of this approach for evaluating prognosis.

Objective To explore application of standardized patients (SPs) in intensive training of clinical competency for general practice trainees. Methods Fifty-three general practice trainees in Shanghai Zhongshan Hospital were enrolled in the study, randomly assigned to intervention and control groups. Control group proceeded in routine clinical rotation, while intervention group accepted intensive training course with SPs as trainers. Three months after intervention, clinical skills of the two groups were compared in a simulated medical environment. Results There was no statistically significant difference in their baseline characteristics between the two groups (P ＞0.05). Competency in history taking, physical examinations,communication with patients, comprehensive consultation, medical record writing as well as case-analysis,improved significantly in intervention group after intervention, as compared to those before it ( P ＜ 0. 01 ),with the highest score of communication skill of 82 ± 10. Although competency of history taking, physical examinations, comprehensive consultation, medical record writing also improved significantly three months later in control group as compared to their baselines (P ＜ 0. 01 ), while no statistically significant difference in their communication skills was found ( P ＞ 0. 05 ). Scores of skills in physician-patient communication,comprehensive consultation as well as medical record analysis were significantly higher in intervention group than those in control one after intervention ( P ＜ 0. 01 ), but no significant difference in physical examinations was found between the two groups ( P ＞ 0. 05 ). Conclusions Application of SP in intensive training course for clinical competency can remarkably improve their competency in interpersonal communication and comprehensive consultation for general practice trainees.

Objective To assess clinical competencies of trainees with standardized patients(SPs)and explore reform in methods of assessment for trainees at their completion in standardized training for general practice.Methods Totally,52 trainees in clinical training bases for general practice in Shanghai attended the examinations.Their skills in commanication skills,information and data gathering,comprehensive consultation,clinical thinking and decision-making in diagnosis and treatment were examined by rotation of three serial assessment stations in a specified time to perform standardized tasks,including medical history-taking,physical examinations(PE),medial record writing and oral tests.Results Scoresof history-taking,PE and skills of communication with SPs were higher than those agsessed by examiners themselves.but they both correlated each other with a P-value less than 0.01,with the highest coefficient of correlation of 0.774 between score of PE and that assessed by examiners.There was significant difference in average score among all clinical skills(F=9.867,P＜0.01),with the lowest one of comprehensive consultation skills of 64±22(P＜0.01).Skills of communication with patients had the highest correlation with data gathering ability(r=0.582,P＜0.01).Results of analysis for influential factors showed no significant difference in average score for all skills between men and women trainees(P＜0.05).Average score of comprehensive consultation ability in those with work experience was lower than that in thoge without it(P＜0.05)and no significant difference in scores of all the other skills wag found between those with varied length of working(P＞0.05).There was significant difiefence in average scores of communication skills,medical record writing,and case analysis between various trainees(P＜0.01).In addition,average scores of information collecting and medical record writing also differed among trainees from varied bases for general practice training(P＜0.05).Conclusions Clinical skills,ability to direct teaching work,and improvement of teaching model can be assessed in a comprehensive and objectively way using standardized patients in general practice training.
