Objective To study the diagnostic value of high frequency color doppler ultrasound acute appendicitis.Methods 98 patients with symptoms of acute appendicitis were selected,the application of Logiq 9 color Doppler ultrasonic diagnostic apparatus,a frequency of 7 ～ 10.0MHz was wsed.The McBurney point as well as around the right lower quadrant tenderness of rebound pain at the obvious on the miter,slitting,transverse scanning.Combined with color Doppler flow imaging to understand the flow conditions.After diagnosis of the patients with operation of diagnosis and treatment,the histopathology of the final diagnosis with ultrasound diagnosis results were compared,and through statistical analysis,identifying all patients with the rate of misdiagnosis,missed diagnosis rate,positive rate.Results The exploration and operation pathology diagnosis results contrast,all 98 patients,diagnosed in 95 patients,the positive rate was 96.9％ ;1 cases were missed diagnosis,misdiagnosis missed diagnosis rate was 1％ ;in 2 cases,the misdiagnosis rate was 2％.Conclusion High frequency color doppler acoustic in the diagnosis of acute appendicitis diagnosis rate was high,with clinical practical value.

Objective To observe the value of myocardial performance index (Tei index) in evaluating the left ventricular function in diabetic patients with normal left ventricular ejection fraction (LVEF),and to investigate its correlation with plasma N-terminal pro-brain natriuretic peptide (NT-proBNP).Methods 96 diabetic patients with normal LVEF were selected as the observation group,50 healthy persons were selected as control group.Left ventricular Tei index was measured by color Doppler ultrasound.The plasma NT-proBNP was detected.Results The Tei index,plasma level of NT-proBNP of the observation group were (0.49 ± 0.11),(397.6 ± 39.4) ng/L,those of the control group were (0.32 ± 0.07),(101.2 ± 18.4) ng/L,the differences between the two groups were statistically significant(t =11.357,1.992,all P ＜ 0.05).There was significant positive correlation between Tei index and plasma NT-proBNP in the observation group(r =0.661,P ＜ 0.05).Conclusion Combined determination of Tei index and plasma NT-proBNP can detect early myocardial damage in patients with diabetes mellitus.

Preventing the nitrate and nitrite pollution of vegetable have an important value to ensure the public health. The content of nitrate and nitrite in vegetable is not only controlled by fertilization and management in produce. But correlated with handling process after collection. Based on the past document this paper play emphasis on the change trend and the cause of nitrate and nitrite content in vegetable during the process of storage, boiled water poaching,immersing,machining and so on. Finally give some advice on improving current research.

Objective To investigate the effect of long-term cardiac rehabilitation on risk factors with doctor supervision after percutaneous coronary intervention(PCI). Methods One hundred and twelve patients after PCI were divided into the cardiac rehabilitation group(56 cases) and the control group (56 cases). All of the patients were given medication and health education, meanwhile the cardiac rehabilitation group received 4～6 weeks hospitalized cardiac rehabilitation program and one year ambulatory cardiac rehabilitation with doctor supervision. Risk factors were assessed six mouths and twelve mouths after the treatment. Results The risk factors except diastolic blood pressure and body weight index improved more significantly in the cardiac rehabilitation group than in the control group. Clinical event in the cardiac rehabilitation group is lower than in the control group. Conclusion Long-term cardiac rehabilitation with doctor supervision is safe, efficiency and good compliance to improve risk factors of coronary heart disease after PCI except diastolic blood pressure and weight management.

This paper introduces a brand-new three-way trachea tube reinforced by steel.It has a three-way junction.The main tube has the function of ventilation and connection,while the side tube which can be connected to oxygen-breath tube is used for the autonomic breath of the patient or for nurses to draw secretions.Furthermore,the steel wire is inserted in the tubes in case it is snapped.

Objective To investigate the relationship between daily physical activities determined by walking-steps and the obesity indices including body weight，Body Mass Index (BMI)，waist and hip circumference and their ratio in adults. Methods 125 individuals who participated in routine physical examinations of health were measured with body weight, BMI, waist and hip circumference/ratio, daily physical activities determined by walking steps. Results For males, daily physical activities correlated negatively with body weight （r=-0.397，P＜0.01）, BMI （r=-0.499，P＜0.01）, waist circumference （r=-0.490, P＜0.01） and the ratio of waist vs. hip circumference （r=-0.478，P＜0.01）, whereas body weight（r=-0.342，P＜0.01）, BMI （r=-0.249，P＜0.05）, and hip circumference （r=-0.303，P＜0.05） for females. Daily walking-steps were significantly different among the groups of normal weight (11491±6100) steps/d, overweight (9314±5722) steps/d, and obesity (6141±2985) steps/d (P＜0.01). Conclusion Daily physical activities determined by walking steps correlated significantly with obesity indices.

Objective To investigate the relationship between daily walking-steps and serum lipids.Methods 120 individuals who participated in routine physical examinations of health were investigated, objective measurements included triacylglycerol (TG), total cholesterol (TC), low density lipoprotein (LDL) and high density lipoprotein (HDL), and daily walking-steps were determined by pedometer.Results The daily walking-steps were correlated negatively to TG ( r=-0.351, P＜0.01), and positively to HDL ( r=0.284, P＜0.05) for male after adjustment for age.Conclusion Daily walking-steps determined by pedometer are correlated negatively to TG levels, and positively to HDL levels for male. No correlations are found between daily walking-steps and levels of TC, LDL for male. No correlations are found between daily walking-steps and serum lipids for female.

Objective To investigate the relationship between objectively determined daily physical activities and blood pressure levels in Chinese adults. Methods 125 individuals who participated in routine physical examinations of health were investigated, include systolic pressure, diastolic pressure, pulse pressure, and daily walking steps determined by pedometer. Results The daily walking steps correlated negatively with systolic pressure（Male r=－0.613, P＜0.01; Female r=－0.430, P＜0.01） and diastolic pressure (male r=－0.686, P＜0.01; female r=－0.388,P＜0.01). Daily walking steps of normotensive, pre-hypertensive, and hypertensive groups were (18249±6066) step/d, (10395±3788) step/d, (6232±3967) step/d for males, and (12564±6927) step/d, (11458±5084) step/d, (6153±3569) step/d for females respectively （P＜0.05）. Conclusion The daily physical activity determined by walking steps correlated negatively with blood pressure in Chinese adults. Hypertensives often live in low active or sedentary lifestyle. Active lifestyle （≥10000 step/d） may help keep normal blood pressure for Chinese adults.

Objective To investigate the efficacy of the oxygen uptake efficiency slope (OUES), obtained from submaximal exercise, as an index of cardiopulmonary functional reserve in adults. Methods Exercise tests, following a symptom-limited standard Bruce protocol with simultaneous respiratory gas measurement, were performed on a treadmill in 33 healthy adults free of clinically recognized cardiovascular disease and 31 patients with heart disease. The OUES was derived from the relation between oxygen uptake (VO2) and minute ventilation (VE) during incremental exercise and was determined by VO2=alog10VE+b, where a=OUES. The OUES was calculated from data of the first 75%, 90% and 100% of exercise duration (as 75%OUES，90%OUES and 100%OUES). Results The 100%OUES，90%OUES and 75%OUES were not significantly different from each other（F=0.212，P=0.809）. The 75%OUES was slightly lower (1.9%) than the 100%OUES. The 100%OUES, the 90%OUES and the 75%OUES correlated with the peak VO2 （r=0.836,r=0.824 and r=0.777, P<0.001, respectively）. The VAT correlated with the peak VO2 （r=0.878，P<0.001），and the VE/VCO2 at VAT correlated with the peak VO2 （r=-0.584，P<0.001）. The 100%OUES correlated with the 90%OUES and the 75%OUES （r=0.991 and r =0.945, P<0.001, respectively）. Conclusion The OUES is an index of exercise performance and cardiopulmonary functional reserve on healthy adults and patients with cardiac disease. The 75%OUES from submaximal exercise can be an index of cardiopulmonary functional reserve for patients with cardiac disease.
