A Review Many studies indicate that apoptosis is involved in the progression of congestive heart failure. At present, mechanisms that mitochondria regulates cell apoptosis is widely accepted.Cardiac myocytes have abundant mitochondria,which plays an important role in maintenance of cell physiological function. Recent studies find that cardiac energy metabolic shifts occur as a normal response to diverse physiologic and dietary conditions and as a component of the pathophysiologic processes which accompany cardiac hypertrophy, heart failure, and myocardial ischemia.Both clinical and experimental studies show that cardiac function can be improved and apoptosis is inhibited by intervention in energetic metabolism of myocytes.

OBJECTIVE:To evaluate the status and tendency of the application of antihyperlipidemics drugs in Chongqing area. METHODS: The use of antihyperlipidemics drugs in 28 hospitals of Chongqing from 2004 to 2007 was analyzed statistically in respect of the consumption sum, DDDs and DDC. RESULTS: The mean annual incremental ratio of the consumption sum of antihyperlipidemics drugs reached over 33.80%. Simvastatin has been dominated the first place over the 4 years in terms of consumption sum and DDDs; the consumption sum of atorvastatin has been on the rise but that of Gemfibrozil decreased year on year with mean annual decrement of 60%. CONCLUSION: Statins assumed a dominant position among all the antihyperlipidemics drugs used in Chongqing area and its use has great potential.

Objective To investigate the effects of the serum from chronic renal failure (CRF) rats on endoplasmic reticulum stress (ERS) and activation of activating transcription factor 4 (ATF4) of rat arterial smooth muscle cells (ASMCs) cultured in vitro and explore the possible mechanism. Methods The rat model of CRF was established by 5/6 nephrectomy. ASMCs were incubated in the media with 10% or 20% serum of CRF rats cultured in vitro. ATF4 nuclear translocation were analyzed by immunofluorescence. GRP78 (glucose regulated protein 78), p-PERK (pancreatic ER kinase) and ATF4 proteins in response to the CRF serum in ASMCs were determined by Western blot. The ATF4-DNA binding activity was analyzed by electrophoretic mobility shift assay (EMSA). Results The CRF serum could significantly promote the expression of GRP78 of ASMCs in dose-dependent manner. Under the stimulation of 20% CRF serum, nuclear translocation of ATF4 in ASMCs was found. Compared with control serum group, the expression of ATF4 and p-PERK of CRF serum group was increased significantly (P<0.01). The CRF serum could increase the ATF4-DNA binding activity. Conclusion The CRF rat serum can effectively induce ERS of ASMCs and activate the pathway of PERK-ATF4.

Objective To investigate the effect of ulinastatin on postoperative cardiac troponin I ( cTnI) in patients underwent carotid endarterectomy ( CEA) under general anesthesia. Methods Forty patients with severe symptomatic carotid artery stenosis underwent unilateral CEA under general anesthesia from January 2011 to March 2012 were divided into either a ulinastatin group or a control group according to a random number table ( n=20 in each group) . Patients in the ulinastatin group received 500 000 U of ulinastatin via veins before induction of anesthesia. The patients in the control group were given the same amount of isotonic saline. The serum concentrations of cardiac troponin I ( cTnI ) were detected before surgery and at day 1,2,and 3 after procedure. Myocardial injury was defined as the cTnI peak concentration>0. 04μg/L . Results The levels of serum cTnI before procedure and at day 1,2,and 3 after procedure in the ulinastatin group were median (M) 0. 00 (0. 00-0. 03) μg/L,0. 07 (0. 00-1. 45) μg/L,0. 01 (0. 00-1. 21)μg/L,and 0. 05 (0. 00-0. 89)μg/L,respectively;those in the control group were 0. 00 (0. 00-0. 01)μg/L,0. 00 (0. 00-1. 42)μg/L,0. 00 (0. 00-1. 39)μg/L,and 0. 00 (0. 00-1. 24)μg/L, respectively. At day 1 after procedure,6 patients ( 30%) in the control group and 11 ( 55%) in the ulinastatin group occurred myocardial injury. There was no significant difference between the two groups (P<0. 05). In all the patients with the increased cTnI levels,the peak cTnI occurred at the first day after procedure,however,they did not reach the level ( >1. 5μg/L) of indicating patients occurring myocardial infarction. Conclusion Ulinastatin may not decrease the postoperative serum cTnI levels in CEA patients under general anesthesia. For whether to the CEA patients have myocardial protective effect,more samples are needed to be confirmed.

Objective To investigate the situation of implementation of community home endowment nursing services in Yancheng City to provide basis for developing nursing services for the elderly.Methods Survey was conducted for the 255 elderly in 15 aged-service stations.We used the multistage random sampling by questionnaire and interview.Results There was difference in the need of community home endowment service,the situation of implementation,and in the service evaluation.Conclusions Nursing service for old people in community home endowment is still developing in elementary step.We should establish the normative and exercisable quality specifications and evaluation systems of nursing service for old people,in order to assure quality of nursing service.
