Objective To study the interventional effects of Candesartan Cilexetil on vascular endothelial function and expres-sions of ERK/CREB signaling pathway in rats with acute myocardial infarction.Methods 30 rats were randomized into CAN group,AMI group and Sham group.Two weeks after the treatment rats were sacrificed and blood pressure,levels of blood AngⅡ, NO and NOS,endothelial vasomotor effects of isolated thoracic aorta strips,myocardial infarctual area and the expressions of ERK mRNA and CREB mRNA in infarctual myocardium were explored.Results Blood AngⅡ levels were distinctly higher in AMI group when compared with the Sham group,while the NO and NOS level were much lower.accompanied with EDDs decreased seri-ously,and higher mRNA expressions of ERK1 and CREB in infarctual myocardium.All of the above differences were significant. After the treatment of Candesartan Cilexetil,levels of serum NO and activities of NOS were obviously higher and almost reached the similar levels to those in Sham group,additionally endothelium-dependent diastole in isolated aortic strips improved greatly.Mean-while Candesartan Cilexetil can not only increase the plasma AngⅡ,but also decrease the size of myocardial infarction and the mR-NA expressions of ERK1 and CREB in infarctual myocardium significantly.However,blood pressure in all groups was not affected. Conclusion Candesartan Cilexetil can greatly improve the disordered endothelial function developing post-AMI,decrease the size of myocardial infarction and down-regulate the mRNA expressions of ERK and CREB in myocardium of infarctual zone.And all of the above protective effects of Candesartan Cilexetil were independent on blood pressure lowering.

Objective To investigate the different effect among ropivacaine,bupivacaine,lidocaine on analgesia after harvesting grafts from the scalp in burn patients. Methods 84 patients who need harvesting grafts from the scalp after burn were divided in 4 groups random-ly(n=21). Patients in group C hypodermically injected with saline 200 mL were control,while patients in group R injected with 0. 05% ropi-vacaine 200 mL,group B with 0. 188% bupivacaine,and group L with 0. 1% lidocaine. Motor activity assessment scale( MAAS) and visual analogue scale(VAS) were made before anesthesia(T0) and 20 min,5 h,10 h after awake of patients. VAS were made focus on head and body in part. Vital signs were also monitored and recorded for assessment of security. Results All patients in 4 groups had passed the period of operation safely. Patients in group R have better VAS than other groups. Conclusion Low concentration ropivacaine hypodermically injec-tion of head is helpful to relieve the pain after harvesting grafts from the scalp.

Objective To measure the financial burden incurred by hypertension to urban patients in Beijing, Nanjing and Hangzhou cities. Methods Two communities were sampled from the three cities randomly, and 300 hypertension patients were sampled randomly from hypertension control files in each community for questionnaire survey. Results Health expenditure of the families with hypertension patients accounts for 14. 4% of the family's income, and 18. 2% of the family's expenditure, a ratio far beyond the national average (10.6 %). However, the majority of them report the burden as affordable.The basic medical insurance for urban residents helps alleviate the financial burden of hypertension patients and the extent of such burden has a close bearing on the outcome of hypertension treatment and prevention. Conclusion Effective community-based blood-pressure monitoring and control system is key to reducing the financial burden of hypertension. The reimbursement policy for hypertensive patients within the basic medical insurance is expected to be further improved.

Objective To understand the current situation of iodine deficient disorder(IDD) 10 years after achieving the stage goal of eliminating IDD in Longyan city and to evaluate the effect of prevention and treatment measures, and to provide the basis for the development of control strategies. Methods There were 7 counties in the city, and each county(city, district) was as a unit to carry out the inspection for organization and leadership,iodine salt management, monitoring and control, health education (referred to as the four management indicators)according to "The County-Level Assessment and Evaluation Implementation Detailed Rules of Realizing the Goal to Eliminate IDD in Fujian Province". According to the east, west, south, north and middle positions in each county,a village and a primary school were selected. Forty 8 to 10 year-old students in each school were randomly selected to check thyroid and among them 20 students were collected urine samples to determine urinary iodine. Nine townships were selected in the 7 counties of the city and among which 4 administrative villages were selected in each township. Eight edible salt samples from each household in each administrative village were collected to test salt iodine. Goiter was examined by palpation, the level of urinary iodine was examined by arsenic and cerium spectrophotometry, salt iodine was detected by direct titration. Results The average score of the four management indicators was 94.1 in Longyan city. The adjusted goiter rate of children aged 8 - 10 years old was 1.9%. The median of urinary iodine was 278.6 μg/L, among which less than 100 μg/L accounted for 4.57%(32/700), 100 -< 200 μg/L accounted for 24.00%(168/700), 200 - < 300 μg/L accounted for 25.29%(177/700), and higher than 300 μg/L accounted for 46.14%(323/700). The using rate of qualified iodized salt was 98.86%. The coverage rate of iodized salt was 99.50%, the qualified rate of iodized salt was 99.35%, and the rate of non-iodized salt was 0.50%. All the indicators had reached the national standard to eliminate IDD. Conclusions After achieving the stage goal of eliminating IDD, the disease is stable and the effect of control measures are significantly. But the iodine provided has a trend of more than suitable. Therefore, it is reasonable to reduce the current salt iodine content.

AIM :To investigate the association of primary open-glaucoma (POAG), intraocular pressure (IOP) and systemic blood pressure in a rural population aged 50 years old or above in Shaanxi Province, China.METHODS: In the population-based, cross-sectional study, 1 775 (83.53%) residents, aged 50 years old or above, from 3 counties of Shaanxi Province, China, undertook an interview with a standard questionnaire and a detailed eye examination, including logarithm of the minimum angle of resolution visual acuity, slit-lamp biomicroscopy, applanation tonometry and dilated fundus examination. Two blood pressure reading in the sitting position were taken. Gonioscopy was performed if a narrower peripheral anterior chamber (less than one fourth of the corneal thickness) was indicated. Automated visual field testing was performed by participants assessed to have suspicion of glaucomatous disc damage or if IOP was 22mmHg or higher.RESULTS: IOP significantly correlated with systemic blood pressure, and both IOP and systolic blood pressure increased significantly with increasing age. No association between POAG and hypertension was found. The frequency of POAG increased significantly with lower diastolic perfusion pressure.CONCLUSION: Data in our study are accordance with those reported in other population-based studies, and confirm that lower diastolic perfusion pressure is a significant risk factor for primary open angle glaucoma.

AIM: To assess the prevalence and risk factors for age-related macular degeneration (AMD) in a rural population in Shaanxi Province of China.METHODS: A total of 2 835 (81.00%) people aged 40 years old or more, from Fuping county, Jingbian county and Yang county of Shaanxi Province, China, underwent a comprehensive interview and a relative eye examination. The present of AMD was classified into neovascular AMD (NV) and pure geographic atrophy (GA) by using direct ophthalmoscopy for fundus examination according to International Classification System.RESULTS: The prevalence (95% CI) of AMD was 3.00% (2.42, 3.71) in this population, of which NV accounted for 1.45% (1.05, 1.98) and 1.55% (1.14, 2.10)for GA. The prevalence of AMD increased significantly with increasing age (P <0.001). AMD was present in 0.47% of participants aged 40 to 49 years, rising to 11.90% of participants older than 80 years, of which the corresponding data increased from 0.28% to 4.76% for NV and from 0.19% to 7.14% for GA. No significant difference was found in the prevalence of NA and GA between genders in this population. With multiple logistic analyses, apart from advancing age, only smoking was found to have a strong association with any type of AMD.CONCLUSION: The prevalence of AMD in the rural population of Shaanxi Province of China is lower than that reported from other population-based studies in different provinces of China, less than that reported in whites, more than that reported in blacks. Except increasing age, smoking is also a significant well-known risk factor for AMD.
