Objective To explore the predicting role of organism weak magnetic field analytic technology on heart functions in individuals with normal electrocardiogram(ECG).MethodsA total of 1534 subjects who receired health examinations and organism weak magnetic field tests in Health Science Center of Chinese PLA General Hospital from May to June 2009 were enrolled.Positive rates of organism weak magnetic field analytic technology,echocardiography,and myocardium enzyme test for heart dysfunction among populations with hypertension,hyperglycemia and hyperlipidemia were compared.Statistical analysis was carried out to detect if there was close correlation between different heart risk and the weak magnetic field index.Results(1)The positive rate of the organism weak magnetic field analytic technology for heart dysfunction among subjects with normal ECG was 96.0%(1472/1534),which was significantly higher than echocardiography(27.5%,200/726)and myocardium enzyme testing(6.9%,106/1532).The positive rate of organism weak magnetic field analytic technology was increased with the seriousness of hypertension ,hypergjycemia and hyperlipidemia(P＜0.05＝.(2)Different heart risks showed close correlation with heart meridian and potassium(P＜0.05＝.Conclusion The prediction of organism weak magnetic field analytic technology on potential heart dysfunction(as a result fromhypertension,hylperglycemia and hyporlipidemia)in individuals with normal ECG is highly sensitive andrelatively objective.

Objective To explore predictive effects of organism weak magnetic field analytic technology on heart diseases among adults with hypertension,hyperglycemia and hyperlipidemia.Method A total of 1534 individuals who received health examinations and organism weak magnetic field tests in Health Science Center of Chinese PLA General Hospital from May to June 2009 were enrolled.Statistical analysis were carried out to detect if the heart function index of organism weak magnetic field tests could identify different conditon for the incident dysfunction of heart in low-,potential-,high-risk groups classified by the three high agent using the nonparametric test.High-dangerous three-high groups include simple,compound,additional and assembling sorts of combining types.Results The quantitative values of heart meridian of one potential-risk and nine high-risk three-high groups differs evidently from the low-risk high-risk three-high groups by Moses test(P ＜ 0.05).There was statistically significant difference of the quantitative values of heart meridian,potassium,magnesium,manganese,cardiovascular,circulaton,heart endocrine,and T2 among the low-,potential-and high-risk levels and other different types of three-high groups by Wilcoxon rank sum test(P ＜ 0.05).Conclusion Organism weak magnetic field analytic technology could reveal change of heart dysfunction in individuals with normal electrocardiogram.

Objective: To study the expression of bone morphogenetic protein (BMP)-2 during midfacial sutural distraction osteogenesis in dogs and to probe the mechanism of sutural distraction osteogenesis. Methods: Eighteen mongrel dogs (12-week old) were randomly divided into distraction osteogenesis group(n = 12) and the control group(n = 6). Rigid external distractor was used for sutural distraction of the midfacial skeleton in the experimental animals. Two experimental and one control dogs were sacrificed at defined time points (on the 5th,10th and 15th day of distraction, the 10th and 20th day of fixation, and 30th day after completion of fixation). The expression of BMP-2 was observed by means of immunohistochemistry. Results: During the period of distraction and fixation, positive staining of BMP-2 was found in the proliferated preosteoblasts, the mesenchymal cells and the newly formed bone matrix at the sutural margin of the experimental dogs; weak expression was also noticed in the control dogs. Compared with that in the control group, the expression of BMP-2 in the experimental group increased and reached the peak on the 15th of distraction, then gradually decreased, the expression of BMP-2 nearly restored to the normal level 1 month after the removal of the distractor. Conclusion: The mechanical strain can lead to the generation of endogenous BMP-2, which may play an important role in the new bone formation.

Ketamine is mighty and short effective antalgic, advantaged in shock, asthma, etc. but it is restricted clinically because of serious side-effect. Today, low-dose ketamine(≤1 mg/kg) combined with opiates can enhance the efficacy of the opiates so that the dose of the opiates decrease relatively. The ketamine-opiates solution has enough stability and respiratory problems don't appear. So it is feasible that the combination of the two medicines can be used for patients with cervical spinal cord injury, who are susceptive to the respiratory distress and especially for the patients with depression.

Objective To constitute a database of chronic wounds for characterizing the patients with chronic wounds.Methods Based on the guideline of chronic wounds defined by international wound healing society,86 outpatients with chronic wounds were selected between January and October in 2013 to set up a wound database using the wound information management system.The parameters including etiology,age distribution,mean time of fracture healing and wound healing time posterior to different treatments were analyzed.Results (1) Statistical difference existed for cause distribution (P ＜0.05).Top three causes were trauma (29％),varicosity (26％) and pressure sore (19％).(2) Age distribution varied significantly among the patients with various causes of chronic wounds (P ＜ 0.05).(3) Statistical difference was observed in healing time of various types of chronic wounds (P ＜ 0.05).Diabetic wound and varicose ulcer took the longest healing time,with average 116.36 days and 88.48 days respectively.(4) Patients treated with novel dressings had shorter healing time than those managed with traditional dressings (P ＜ 0.05).Conclusions Trauma,varicosity and pressure ulcer are relatively common among the outpatients.Etiology of chronic wounds is strongly related to age and novel dressings contributed to a shortened cause of the disorder.

This paper reports the study and design of a visualization system of the ultrasonic rhinitis therapeutic apparatus with the function of endoscopic sinus. On Linux operating platform, we captured the video data of a video capture card that connected the endoscopic sinus using Video4Linux (V4L2) that was provided by the operating system. The video images were displayed by Qt. The visualization system solved the problem that the current ultrasonic rhinitis therapeutic apparatus had to rely on the large and expensive endoscopy equipment. And this simplified the doctors' operation, met the need of monitoring nasal cavity in the process of operating, greatly reduced the costs of treatment and would contribute to the promotion of the instrument. As a result, it has been tested that the nasal endoscopic image achieved by the system is clear and smooth, and fully meet the clinical needs of ultrasonic treatment of rhinitis.

Objective Serum glycated albumin (GA) is associated with the levels of blood glucose and short term glycemic fluctuation. The aim of this study was to investigate the associations between GA and arterial stiffness in a health screening population. Method A total of 11 014 participants (men, 56.2%;mean age, 46.8±7.8 years) who attended physical examination were invited and had completed standardized questionnaires. Serum GA and homocysteine (HCY), brachial-ankle pulse wave velocity (baPWV), and central systolic blood pressure (cSBP) were measured. A series of single and multiple factor analyses and stratified analysis were performed. Result The mean level of serum GA was lower in men (13.69 ± 2.69) than in women (13.82 ± 1.92) (t=2.78, P=0.005). The values of baPWV (men: F=53.9, P for trend<0.001;women:F=37.7, P for trend<0.001) and cSBP (men:F=10.3, P for trend<0.001;women:F=13.5, P for trend<0.001) increased with quartiles of GA levels in both men and women. After adjustment for age, history of hypertension, diabetes, family history of diabetes, smoking status, body mass index, waist circumference, blood pressure, blood lipids, kidney function, fasting glucose, postprandial glucose, and hemoglobin A1c, GA was positively associated with baPWV (βestimate, 0.019;95%CI:0.002-0.036;P=0.032) and cSBP (βestimate, 0.251; 95% CI: 0.107-0.394; P=0.001) in men. Stratified analysis also showed that the positive associations of GA with baPWV and cSBP remained significant in men both with and without diabetes or hypertension (P<0.05). However, the association between GA and HCY was not significant in multifactor analysis and stratified analysis. The above results were similar in women. Conclusion Serum GA levels were positively associated with baPWV and cSBP not only in patients with diabetes or hypertension but also in participants without diabetes or hypertension after adjusting for conventional factors and glucose markers. The findings suggest that GA may help detect the development of arterial stiffness in the health screening population.

Objective To evaluate the efficiency of ten years of iodized salt supply in prevention and control of iodine deficiency disease (IDD) in Tianjin. Methods 1 200 pupils aged 8-10 years with 1:1 of sex ratio were chosen in the regions where iodized salt supply had been conducted for 10 years (1995-2005), the prevalence rate of goiter, the level of urine iodine and the iodized salt consumption were investigated. Results The prevalence rate of goiter of children aged 8-10 years in Tianjin decreased from 32.6% to 1.8% after 10 years of iodized salt supply, the median of urinary iodine increased from 96 ?g/L to 228 ?g/L. In the high water iodine regions, the prevalence rate of goiter was 8.1%, the median of urinary iodine was 576 ?g/L. Conclusion 10 years of iodized salt supply can significantly prevent and control IDD in the regions where there is iodine deficiency in drinking water, but the problem should not be neglected that iodine excess in the regions where the concentration of iodine in drinking water is higher. Reasonable iodine supplement is the key to prevent and control IDD as a whole.
