Objective: China Heart Failure Registry Study (China-HF) is aimed to understand the etiology, clinical features and treatment of in-hospital heart failure (HF) patients in China. Methods: Based on geographic region and economic condition, we prospectively recruited the in-hospital patients with primarily diagnosed HF, and the demographic information, etiology, clinical features and treatment condition were collected by electronic case report form in all patients. Results: A total of 8516 HF patients from 88 participating hospitals between 2012-01 and 2014-12 were analyzed. The average age of patients was at 66 years with 54.5% male. There were 6777/7997 (84.7%) patients with NYHA functional classiifcation at III-IV, 4207/8516 (49.4%) with coronary artery disease (CAD), 4649 (54.6%) with hypertension, 2109/7102 (29.7%) with chronic kidney disease and 2478/6608 (37.5%) with left ventricular ejection fraction (LVEF) < 40%. The patients with infection 3909/8516 (45.9%) and exertion or stress 2214 (26.0%) and myocardial ischemia 1967 (23.1%) were the major cause of HF worsening. There were 6165/8516 (72.4%) patients treated by intravenous diuretics during hospitalization, and after discharge, 5722 (67.2%) patients received oral loop diuretics, 2563 (30.1%) received angiotensin converting enzyme inhibitor, 2095 (24.6%) received angiotensin II receptor antagonist. The median length of in-hospital stay was 11 days and the in-hospital mortality was 5.3% (451/8516). Conclusion: China-HF provides a comprehensive insight of clinical features for the in-hospital HF patients in China. There is still a gap for medications between our current condition and the guideline, it is important to educate both patients and physicians in clinical practice.

The treatment for chronic heart failure has been changed significantly in recent 20 years.Therapeutic target in heart failure not only improves symptoms and quality of life,more important is for the mechanism of myocardial remodeling,prevent and delay the development of myocardial remodeling.Angiotensin converting enzyme inhibitor/angiotensin receptor blockers,beta blockers,and aldosterone inhibitors are used as the golden triangle drug therapy for chronic heart failure.In recent years,it has been or is about to carry out some clinical new drugs for the treatment of chronic heart failure.

Objective:To research the application value of coronary CT angiography(CTA) detection for epicardial adipose tissue(EAT) and pericardial adipose tissue(PAT) in the diagnosis of coronary stent restenosis.Method:Selected 68 cases coronary atherosclerotic stenosis patients who were treated by coronary stent from June 2012 to June 2013 in hospital. All patients were detected after the operation of CTA within 3 years and they were divided into two groups (coronary stent restenosis positive group included 29 cases, negative group included 39 cases). To analyze the relationship between EAT and PAT through the statistical method and analyze the application value of EAT and PAT in the diagnosis of coronary stent restenosis based on calcification score image measurement of EAT and PAT volume.Results: Correlation analysis results showed there was correlation between EAT volume and PAT volume (r=0.859,P<0.05); through compared CAG and the diagnostic results of coronary artery stent restenosis by EAT and PAT, the sensitivity was 82.87%, specificity was 84.62%, CCTA positive predictive value was 80.00%, negative predictive value was 86.84% and diagnostic accuracy was 83.82% of the stent patency which was evaluated by CAG. The consistency evaluation marker Kappa was 0.554. The analysis of patients with coronary stent restenosis showed that there was significant correlation between Gensini score of coronary stent restenosis and EAT and PAT(P<0.05).Conclusion:There was significant correlation between EAT volume and PAT volume, and they can be used to evaluate the sensitivity and specificity of coronary stent operation restenosis and the results were higher. Besides, its clinical diagnostic value was similar with CAG.

The aim of this review is to detect the difference in outcome of cardiac resynchronization therapy (CRT) between ischemic cardiomyopathy (ICM) and non-ischemic cardiomyopathy (NICM).By reviewing some clinical trials of large scale,we found that restore of heart structure and function in NICM was more significant than ICM.However,there were no significant differences in clinical outcome of improving cardiac function and quality of life,decreasing heart failure re-hospitalization and mortality.

Using the prime b(special to M. tuberculosis) to amplify 21 mycobacterium and 13 nonmycobacterium, the products amplified were detected by agarose gel electrophoresis. The sensitivity was 50fg at annealing temperature 61℃,and only M. tuberculosis, M. gastri were amplified, those results showed: the clinical isolated mycobacterium can be differentiated and detected quickly and efficiently by using the prime b(using the prime a when necessary) to amplify 16S～23S rDNA spacer sequence of mycobacterium.

Objective To investigate the current status of healthcare-associated infection(HAI) management professionals in county and above levels of traditional Chinese medicine(TCM) institutions in a province.Methods The uniform questionnaires were adopted to investigate the basic status of HAI professionals in county and above levels of TCM institutions in a province.Results There were 117 county and above levels of TCM institutions in this province,85 TCM institutions participated the investigation,there were a total of 128 professionals,including 82 professionals in 65 secondary hospitals,and 46 in 20 tertiary hospitals.Among the investigated TCM hospitals,83 (97.65 ％) set up HAI management committees,77 (90.59％) set up independent HAI management departments,55 (64.71％) assigned HAI professionals that met The Requirements of HAI Surveillance Guideline,27 (31.76 ％) exclusively engaged in management of HAI,58 (68.24 ％) were also responsible for other management besides HAI management.Among investigated professionals,91.41％ were nursing staff,55.47％ received undergraduate course or above,54.69％ had intermediate professional titles,61.72％ were at the age of 41-50,45.31 ％ engaged in HAI management for 1-3 years,115 professionals had management certificates.Conclusion The infec tion management in provincial traditional Chinese medicine institutions are understaffed,professional structure is unitary,professional quality is low,leaders in different levels of TCM institutions should enhance HAI management awareness,strengthen the construction of professional quality,and cultivate multi-disciplinary talents as soon as possible.

Objective To investigate the feasibility,operation design and postoperative rehabilitation in ankylosing spondylitis patients with bilateral hips and knees bony ankylosis,who were operated on the 4 joints during one hospitalization period. Method Two operations were performed in one hospitalization period in three ankylosing spondylitis patients on the 2 hip joints and 2 knee joints respectively.One case,the left hip replacement was operated in the first operation,and the right hip and the double knees were operated in the second operation;the other two cases,unilateral hip and knee were operated in two operations respectively.Patients began to contract their lower limbs’ muscles initiatively after narcosis.The limbs were put on the CPM,the hips and knees were bent and extended repeatedly on the third day after operations.The patients began to leave bed and learned to walk 2 weeks after operations.They could walk 100 steps with aids when they leaft hospital. Result In six-month follow-up,the range of hip motion(degree)were 105?~145?(average 135?);the range of knee motion(degree)was 45?~60?(average 54?).The hip’ function score adopted Harris score system:the average of 83 and were all good;the knee’ function score adopted American Association of Knee Surgery score system in 1989:all were excellent except a good one(left knee of first case,the score was 74/75). Conclusion Performing operations on the 2 bony ankylosis hips and 2 bony ankylosis knees in the ankylosing spondylitis patients in one hospitalization period can shorten the treatment cycle,release the distress,and lighten the economic load,meanwhile it is convenient for operation and postoperative rehabilitation.It is better to do the unilateral hip and knee in a single operation.

BACKGROUND: Small conductance,Ca2+-activated potassium(SK)channel,presents in various cell types and plays a crucial role in action potential profile.However,coupling and modulation of calcium and associated molecules to SK2 channel remains unclear.OBJECTIVE: To construct the recombinants of pGBAT7 and target fragments of SK2 gene,so as to observe the coupling and regulation of SK2 channel gene to calcium and other molecules.METHODS: Three pairs of primers of the target fragments of SK2 gene were designed and synthesized based on the full-length sequences of SK2.After being identified,they were individually sub-cloned into the yeast expressive plasmid pGBKT7 to construct pGBKT7-SK2 vectors.The recombinant pGBKT7-SK2 vectors were transformed into yeast AH109 by electroporation,and their activation was tested.The recombinants were extracted from yeast AH109 and verified by electrophoresis and sequencing.RESULTS AND CONCLUSION: The target fragments of SK2 gene by PCR were 411,546 and 729 bp,respectively.Three sub-clones of pGBKT7-SK2 were successfully constructed.Electrophoresis and sequencing showed that the constructed sub-clones of pGBKT7-SK2 met the expected requirements.The recombinant pGBKT7-SK2 vectors transformed into the yeast could be activated.The successful construction of the sub-clones of SK2 gene provides an important material basis for further study in the SK2 channel and function-associated molecules.
