In clinical work of emergency visit and department of cardiology ,some cases are usually encountered , their cardiac troponin levels rise ,but there is no corresponding cardiac ischemic manifestations on ECG ,even no chest tightness and chest pain etc .The present article collected some related data for those patients without acute myocardial infarction but their troponin levels rose abnormally .They were reviewed as follow .

Objective　To explore the microorganism contaminat ion situation and disease incidence in family and requirements of disinfection. Methods　The sanitation conditions in 212 families in Shanghai were investigated, and 200 of them were taken samples for microbiolo gical test. Re sults　I n recent a year, members in 82.1% of families caught diseases caused by microorg anism infection. Only 18.4% of families usually used disinfectant, the disinfect ed object mostly was dishware. 22.8% of samples was contaminated seriously. Fungus was detected in 63.9% of samples. The average positive rate of HBsAg was 4.2%. Conclusions　Domestic environment was potentially cont aminated by microorganism.

It pro vides g uidelines for the safe use and handling of glutaraldehyde as a disinfectant and sterilant in heath care institution by design consideration, proper work practi ces, information on properties and vapor monitoring of glutaraldehyde, and perso nnel qualifications, training, protective attire and health consideration.

Objective To investigate the influence of intensive heart rate control on inflammatory factor and cardiac function in patients with chronic heart failure. Methods From January 2015 to December 2015 ,a total of 120 CHF patients in New York Heart Association(NYHA)functional classes Ⅱ to Ⅳ were enrolled and randomized into treatment group(n=60)and control group(n=60). All the patients were in stable situation af-ter conventional drug treatment. The patients in treatment group underwent intensive heart rate control for target HR (55~60 beats/min)through adjusting the dose of metoprolol sustained-release tablets. The concentration of C-reac-tion protein(CRP),interleukin-1β(IL-1β),interleukin-6(IL-6)and tumor necrosis factorα(TNF-α)were de-tected before and after 6-month treatment. The resting heart rate and the concentration of brain natriuretic peptide (BNP),left ventricular ejection fracetion(LVEF),left ventricular end diastolic diameter(LVEDD)and left ven-tricular end systolic dimension(LVEDD)were measured at the start and 6-months after treatment. Results After 6-month treatment,the resting heart rate of the patients in the treatment group decreased significantly compared with that of the control group(P<0.001). Inflammatory factors(CRP,IL-1β,IL-6 and TNF-α)levels decreased significantly compared with that of control group (P < 0.05). The echocardiography parameters (LVEDD and LVESD)and the concentration of BNP of the patients in the treatment group decreased significantly(P < 0.05), LVEF of treatment group increased significantly(P < 0.05). Conclusion Intensive heart rate control in patients with chronic heart failure can significantly reduce Inflammatory factor levels and improve the cardiac function.
