Objective To study the effect of diabetic education on the patients using insulin treatment.Methods 41 cases of diabetes were trained in three different ways:group education,individual education and self education in the hospital for three to four weeks by a team of nurses.Results The results showed that the total average test score was increased by 4.44 after education.The average test scores was 9.37±0.45 after education and higher than before education (4.93±0.59) ( P <0.001).12.4% of the patients got full scores after education,34.1% of the patients got the excellent scores (≥8) before education.82.9% of patients got excellent scores after education.41.5% of the patients got low scores (<3) before education,and it was only 3.1% after education.For diabetic knowledge accumulating,the effects were significant ( P <0.001).The self care skill and knowledge such as self monitor of blood glucose and urine glucose,foot care were improved ( P <0.001).By education,diet control,exercise,oral hypoglycemic durgs and insulin treatment,FBS and PBS of patients were efficiently controled ( P <0.001).Conclusion Education is an important way for the patients to learn diabetic knowledge,improve the ability of self management

Objective To assess the effects of 670nm LED (light-emitting diode) to protect the photoreceptor from the light-induced damage in a rat model. Methods 32 SD rats were randomly assigned to one of eight groups: untreated control group, the LED-treated control group, three groups of light-induced damage,and three groups of light-induced damage treated with LED. Light-induced damage result from exposing to constant light for 3 hours of different illuminations of 900,1800 and 2700 lx, respectively. The LED treatment (50 mW) was delivered for 30 minutes at 3 hours before the light damage and 0,24 and 48 hours after the light damage. Retinal function and morphology were measured by electroretinogram (ERG) and histopathology assay. Results The illumination of 900 lx for 3 hours did not damage the rat retina. The illumination of 1800 lx for 3 hours resulted in thinner ONL and no OS and IS. The ratio of damaged area/total retinal area was 0.48±0.12, the damaged thickness of ONL/normal ONL (L5) was 0.39±0.07,and the amplitude of ERG b wave was (431±120) μV. With the LED treatment the ratio of damaged area decreased (M6=0.17±0.12, P5/6=0.002), and the ratio of the damaged thickness of ONL also decreased (L6=0.22±0.09, P5/6<0.01), and the amplitude of ERG b wave increased to (1011±83) μV(P5/6 <0.001). The illumination of 2700 lx for 3 hours caused severed damage to the rat retina and the LED could not protect them significantly. Conclusions 670 nm LED treatment has an evident protective effect on retinal cells against light-induced damage, which may be a simple and effective therapy to prevent or to delay age-related maeular degeneration.

Objective To explore clinical characteristics of H-type hypertension in health check-up populations so as to provide evidence for stroke prevention.Methods A total of 42 251 health check-up individuals (male 27 746,female 14 505,average age (46 ± 9) years) who visited our center during May,2009 and February,2012 were enrolled and responded to the investigation.In face to face interview,their age,gender,cigarette smoking and alcohol consumption were recorded.Height,body weight and blood pressures were measured.Serum lipid profiles,blood glucose,uric acid (UA),creatinine (Cr),homocysteine and urine albumin creatinine ratio (ACR) were tested.The subjects were then assigned to the H-type hypertension group,common hypertension group,high homocysteine group and control group.Analysis of Variance was used for data analysis.Results Of 42 251 participants,7748 were found to have H-type hypertension (18.34％ in whole subjects and 63.95％ in hypertensive subjects).Serum level of homocysteine and prevalence of common hypertension and H-type hypertension were significantly higher in males (P ＜ 0.05).Age and body mass index of the H-type hypertension group were significantly increased (P ＜ 0.05).The highest incidence of cigarette smoking and alcohol drinking was found in the homocysteine group (P ＜ 0.05),while the highest serum levels of Hb,UA,high sensitivity-C reactive protein (hs-CRP),and Cr occurred in the H-type hypertension group.Moreover,total cholesterol,triglycide,low-density lipoprotein cholesterol,and microalbumin/creatinine were not significantly different between the common hypertension group and the H-type hypertension group (P ＞ 0.05),although were significantly different between the controls and the H-type hypertensive patients (P ＜ 0.05).Conclusion The prevalence of Htype hypertension may be increased with the increasing serum levels of biological markers for nutritional metabolism.Higher level of homocysteine dose not seem to aggregate lipid disorders and early renal damage.

Objective To investigate the therapeutic efficacy of endoscopic sphincterotomy (EST) for treatment of choledocholithiasis. Methods The clinical data of 326 patients receiving EST from July 1990 to January 2009 were retrospectively analyzed. Long-term follow-up was performed in 195 of the 326 patients. Results The common bile duct stones were removed in 301 cases (92. 33%).The occurring rate of complications after EST was 6.13% (20/326). Of the 20 patients, 10 had pancreatitis (3.07%), 7 hemorrhage (2. 14%), 4 cholangitis (1. 220%) and 1 duodenal perforation (0.09%). Only 1 patient died. The follow-up showed that 20 patients had reflux cholangitis and 18 recurrence of common bile duct stones. Conclusion Therapeutic endoscopy is safe and effective for treatment of choledocholithiasis.

This paper proposed a mobile vital-signs monitoring system based on ZigBee localization and wireless transmission technology for the elderly in nursing home. The system can monitor the vital-signs (pulse, ECG and blood oxygen), localize human body and warn in emergency. The validity and accuracy of this system were testified by the experiments of mobile acquisition and storage of pulse. In these experiments, the measurement of pulse ranged from 50 to 170 time a minute, the mean error of which was less than 3%. The mean error of localizing was less than 4 m. And the data transmission rate was 250 kbps. The system, which effectively conducts the real-time monitoring of the health and safety situation for the elderly, has a great significance for protecting the elderly's life safety.
