Objective To study the effects of standardized-lifestyle intervention on the type 2 diabetic elder patients.Methods The study group enrolled 270 individuals with type 2 diabetes mellitus randomly by using the model of “Zhiji Health Care” and the software of the lifestyle and disease prevention system.Parameters were collected during a six month period for the evaluation,such as fasting plasma glucose(FPG),postprandial glucose(PPG),cholesterol(TC),triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C),body mass(BMI),glycosylated hemoglobin(HbAlc),blood pressure,daily intake,total physical activity and effective physical activity and other indicators.Results After six months' standardized lifestyle intervention:(1)in the type 2 diabetic patients,the parameters of weight,BMI,waist circumference,systolic and diastolic blood pressure were significantly decreased(t values were:23.82,25.91,19.56,23.37 and 19.53,respectively,all P ＜ 0.01); FPG,PPG,HbA1c,TC,TG and LDL-C were significant decreased compared with that before intervention(t values were: 12.06,11.82,9.74,6.98,5.79 and 6.10,respectively,all P ＜ 0.0l).Meanwhile,HDL-C was significantly increased(t =2.51,P ＜ 0.05).(2)the total daily intake was significantly reduced compared with that before intervention.The effective exercise burden was significantly increased,compared with that before intervention(P ＜ 0.01).Conclusion Standard lifestyle management helps to control the blood glucose,blood pressurem,body weight and other risk factors,with reduction of complications and medical costs.

Objective To investigate the etiology, pathology, pathogenesy and treatment in patient with rhabdomyolysis (RM) complicated with acute renal failure(ARF). Methods Analysis of clinical and muscle pathological data combined with literatures were made for a patient with RM-ARF.Results The patient who had experienced exercise induced RM for 5 years. Alcohol drinking and infection were led to RM with ARF for this time. There was non-special inflammatory feature in light microscope by biopsy. The principle of RM management was prevention of hypovolemia and acidification of urine. Hemodialysis (HD)was chosen for treatment of ARF and basic recovery was obtained.Conclusions The etiology of this patient may be the alcohol drinking, particularly the infection which developed on the basis of recurrent RM. Muscle biopsy is useful not only for observing the pathological features of RM, but also for differentiation of etiological factors. The HD therapy used in time may be the key to get favorable effect for this case.

Methods Male wistar rats were divided into five groups,excepted for normal group N,the remnant four groups were all given intraperitoneal injection of porcine serum((0.5) ml/time,2 times/week,total 12 weeks).In KXEH early treatment group B,the rats were fed with KXEH by gavage,1 g/100 g,once a day at the third week.In KXRH late treatment group C,the rats were fed with KXEH by gavage,1 g/100 g,once a day at the ninth week.In ?-interferon treated group D the rats were subcutaneous injection ?-interferon((0.1) million) every day at the ninth week.The model group A and normal group N were fed with the same amount of saline by gavage.The rats were killed at the end of the twelfth weeks,the formation of liver fibrosis was observed with HE stain and Masson stain.The expression of Smooth muscle actin(SMA) was observed by immunohistochemistry.As well as SMA,collagen Ⅰ、Ⅲ mRNA and Smad3 mRNA,which is TGF-?1 downstream signal,were detected in liver samples with RT-PCR assay. Results In KXEH treated group B and C,the body weight was heavier,the size of liver and spleen was smaller and the ratio of liver weight/body weight and spleen weight/body weight was decreased compared with the model group A(P

Objective To establish a method to determine the concentration of Danshensu in rats sera by HPLC after rats were fed with Kangxianerhao(KXEH) extract.Metheds Rats were given 0.45g or 0.55g KXEH extract 7 times in 4 days by gavage,and blood were collected from heart of rats at different time.Condition of HPLC: C18A column was used,the mobile phase was consist of a mixture of acetonitrile-H_3PO_4,the detection wavelength was 205nm.Result Concentration of KXEH reached the highest level one hour after administration of KXEH in different doses,which showed that high dose of drug got higher concentration of drug Danshensu in serum than the medium dose.Linear correlation was obtained over the concentration of 76～1520mg/L,r=0.9932.Average recoveries of samples were 98.3%,101.5%,99.3% respectively at different dose of 76mg/L、304mg/Land 1520mg/L,with RSD was 5.9%、2.5%、2.0% respectively.It was proved indirectly that the concentration of KXEH in rat serum after administraion of KXEH extract reached effective concentration in blood.Conclusion It shows that large dose KXEH get higher concentration of Danshensu in blood than the medium dose.The concentration of drug serum is quantitated by HPLC assay.

Objective To discuss the safety of using etomidate combined with remifentanil by target controlled infusion ( TCI) for painless bronchofibroscopy. Methods Sixty patients were divided into two groups: painless bronchoscopy group (treatment group, 24 patients) and the routine bronchoscopy group (control group, 36 patients). Treatment group received TCI of remifentanil and intravenous injection of etomidate fat emulsion. Control group was subjected to surface anesthesia with 2%lidocaine. SpO2 , blood pressure, heart rate and breath changes during examination and complete awakening were continuously monitored. Bronchofiberscopy time, body movement during examination, bucking and satisfaction degree after examination were also recorded. Results Treatment group patients felt senseless and painless during bronchoscopy, without memory of bronchoscopy and pain. Patients in control group had discomfort, body movement and acute bucking, and most of them had painful memory. There were significant differences between the two groups (P<0. 01). In treatment group, after examination, blood pressure, respiratory frequency, heart rate and SpO2 were significantly decreased (P<0. 01). During examination, the blood pressure, respiratory frequency and heart rate were increased, and SpO2 decreased in control group compared to the baseline (P<0. 01). There was no significant difference in SpO2 between treatment group and control group during examination (P>0. 05). Conclusion TCI etomidate combined with remifentanil during bronchoscopy achieved satisfying anesthetic effect.
