ObjectiveTo explore the diagnosis and treatment of incomplete Kawasaki disease.MethodsA retrospective analysis was applied in 39 children patients clinically diagnosed as Kawasaki disease.ResultsThirtynine cases were found to have a high temperature over 5 days( 100％ ),30 patients with bilateral conjunctival congestion (76.9％),28 cases with cherry pink and chapped lips( 71.8％ ),21 patients with erythema multiforme and erythra(53.8％ ),20 cases with hand-foot scleredema(51.3％ )and 10 patients with cervical lymphatic enlargement (25.6％).In addition to the high temperature,22 cases were found to have three classic clinical diagnostic characterstics(56.4％ ),and 17 patients with two classic characterstics(43.6％ ).During the course of disease,C-reactve protein was observed to increase,and erythrocyte sedimentation rate speed up significantly.Intravenous infusion of gamma globulin and oral administration of aspirin was confirmed to be effective for incomplete Kawasaki disease.ConclusionThe careful observation and complete clinical examination was conducive to early diagnosis of incomplete Kawasaki disease instead of misjudge and missed diagnosis.

Objective To observe the velocity of left ventricular wall motion features of normal subjects and patients with abnormal regional wall movement of left ventricle with the quantitative tissue velocity imaging(QTVI),and to know whether variances exit between the velocity of left ventricular myocardial motion of the normal subjects and the abnormal subjects with coronary artery disease(CAD) and myocardial ischemia. The practical value of QTVI on myocardium movement of left ventricle was evaluated. Methods The segmental left ventricular wall motion velocity was measured on 27 normal subjects and 21 patients with CAD and myocardial ischemia,including three waves,peak velocity of systolic S wave,diastolic E wave,A wave, and time velocity integrate of S wave(S TVI) was used as measurement parameters.The parameters were analysed between the two groups. Results The velocity and S TVI were gradually decreased from base to apex in the same wall in the control group.There were some abnormal segmental movements in the abnormal group. S wave ,E wave and S TVI of diseased segments in the abnormal group were much lower than those of control group ( P  0.05 ). Conclusions QTVI can quantitatively measure the velocity in abnormal movement segment of ventrical wall of patients with CAD and myocardial ischemia.S wave,E wave and S TVI are better parameters of assessing systolic function of left ventricle.QTVI has clinical application in regional myocardial motion function evaluation.

Objective To observe the clinical efficacy of Shenfuyishen Capsule in the treatment of diabetic nephropathy of yangxuxueyu type in high- altitude regions.Methods We divided 53 patients randomly into two groups:31 in the observation group and 22 in the control group.Patients in the control group were treated with conventional regime of Western Medicine.Those in treatment group were given extra treatment with Shenfuyishen Capsule.Then we tested serum creatinine (Scr ),uric acid (UA),urinary microalbumin (MALB )and GFR. Results The total efficiency was 90.32% and 81.82% in the treatment group and the control group,which was significantly different (P < 0.05 ).Major symptoms improved after treatment in both groups,which differed significantly compared with those before treatment (P <0.05).ALT in the treatment group was not different after treatment.CR,UA,MALB and GFR significantly differed before and after treatment in both groups,especially in the treatment group (P <0.05).Conclusion Shenfuyishen Capsule helps improve major clinical symptoms and decrease CR,GFR,UA and MLAB levels in patients with diabetic nephrology,thus protecting renal function and delaying the process of diabetic nephropathy.

Objective To investigate the risk factors and prevention of the ERCP-related upper gastrointestinal bleeding in patients with choledocholithiasis.Methods The clinical data of 678 patients who received ERCP in Yijishan Hospital of Wannan Medical College between January 2014 and December 2014 were reviewed.Univariate and multivariate analyses were performed to define the independent risk factor(s) for delayed hemorrhage following ERCP.Results A total of 383 patients,in whom 157 were males and 226 were females,the age ranged from 19 to 88 years,were recruited to the study.ERCP-related upper gastrointestinal bleeding occurred in 41 patients(10.7％),intraoperative bleeding occurred in 27(7.0％) and postoperative hemorrhage in 14 (3.7％).Twenty-eight cases were mild bleeding,9 moderate (4 caused by laceration of the cardiac mucosa) and 4 were severe bleeding.All patients recovered and were discharged,and no death occurred.No single case required surgical conversion.Univariate analysis revealed that cholangitis,medical history of aspirin/clopidogrel,giant diverticulum and the major papilla inside the diverticulum were risk factors for delayed hemorrhage following ERCP (P ＜ 0.05).Multivariate analysis indicated that independent risk factors were associated with cholangitis (OR =4.125,95％ CI:1.306-13.031,P ＜ 0.05),medical history of aspirin/clopidogrel (OR =10.220,95％ CI:2.997-34.853,P ＜ 0.01) and major papilla occurred inside the diverticulum(OR =14.064,95％ CI:1.888-104.762,P ＜ 0.05).Conclusion Cholangitis,medical history of aspirin/clopidogrel and major papilla at the diverticulum may increase the risks for upper gastrointestinal bleeding in ERCP in patients with choledocholithiasis.However,the hemorrhage should be actively managed,especially in endoscopy,once the bleeding occurs.

Objective To investigate the current situation of psychological capital and job burnout of psychiatric nurses and explore the relationship between psychological capital and job burnout.Methods There were 142 psychiatric nurses collected in the study by convenience sampling.The Psychiatric Capital Questionnaire (PCQ) and Nurse Burnout Scale (NBS) were used to measure the level of psychiatric capital and job burnout of psychiatric nurses.The Pearson correlation analysis was used to explore the relationship between psychological capital and job burnout.Results The psychological capital of psychiatric nurses had a negative correlation with job burnout; the higher of the nurses' psychological capital,the lower their sense of job burnout,vice versa.Conclusions In order to improve nursing quality,nursing managers can reduce the job burnout by improving the psychological capital of psychiatric nurses.

Lung cancer and chronic obstructive pulmonary disease (COPD) are two high-mortality diseases in the world.Numerous epidemiological studies have demonstrated that presence of COPD increases the risk of lung cancer.Habitual cigarette smoking frequently develops lung cancer as well as COPD,However the links between the two diseases should be more than smoking alone.The underlying mechanisms may include genetic predisposition,inflammation and cell injury,oxidative and noxious stress,extracellular matrix and proteinases,some of which might represent the targets for chemoprevention or chemotherapy.
