Objective To evaluate the effect of resistance training on glucolipid metabolism in a population with pre-diabetic metabolism (PDM).Methods Sixty persons with PDM were randomly divided into a resistance training group,an aerobic training group and a control group,each of 20 members.The exercise intervention groups exercised 3 times a week for 12 weeks in accordance with the exercise prescription,while the control group was without any regular aerobic exercise or resistance training.Before and after the 3 months of exercise training,fasting blood glucose (FBG),2 hours postpradial blood glucose (PBG),HbAlc,and lipid profile were tested.Body mass index (BMI),waistline,and blood pressure were also measured.Results Before the intervention,there were no significant differences in any of the average values among the 3 groups.In the resistance group,the average FBS (5.52 ± 0.52 mmol/L),HbA1 c (5.92 ± 0.36％) and TG (1.65 ± 0.92 mmol/L) had all decreased significantly after the training.In the aerobic group the average waistline,dilated blood pressure,FBG and HbAlc had decreased significantly.In the control group the average 2hrs PBG and LDL-C had both increased significantly compared to 3 months earlier.Compared with the resistance group,the average 2hrs PBGs were significantly higher in both the aerobic and control groups after the training.Moreover,compared with the aerobic group,the value in the control group was also significantly higher.Conclusion Both resistance training and aerobic exercise can lower fasting blood glucose and HbA1 c in PDM patients without obvious effect on BMI or low density lipoprotein level.Compared with aerobic exercises,resistance training had significant advantages in decreasing 2-hour postprandial blood glucose.

Objective:To ascertain the optimized ultrasonic condition for extraction of flavone from Radix Astragali by orthogonal design. Methods: The contents of calycosin-7-O-?-D -glucoside and formononetin were taken as the indices and were determined. The ultrasonic time (10 min, 20 min, and 30 min), concentrations of methanol (50%, 75% and 100%) and times of extraction (1, 2, and 3) were analyzed by orthogonal design; the best ultrasonic condition was ascertained and compared with those of soak extraction and Soxhlet extraction. Results: Ultrasonic with 100% methanol twice (20 minutes each time) was the optimized condition for extraction of flavone from Radix Astragali. The efficiency of ultrasonic extraction was better than those of soak extraction and Soxhlet extraction. Conclusion: Compared with other methods, the ultrasonic extraction of flavone from Radix Astragali is efficient, quick and simple.

Objective To investigate the value of preoperative risk assessments and countermeasures on ultrasound-guided radiofrequency ablation for benign thyroid nodules.Methods The preoperative risk assessments of 311 benign solid thyroid nodules in 274 patients were divided into level 0-Ⅳ,among which 38 nodules on level 0,69 nodules on level Ⅰ,36 nodules on level Ⅱ,59 nodules on level Ⅲ,109 nodules on level Ⅳ.Treatments were performed by moving shot technique or multiplanar shot technique,using Leverage Displacement or Hydrodissection to prevent the adjacent vital structures from thermal injuries.Results 311 thyroid nodules were completely ablated.In ablating the 59 nodules on risk level Ⅲ,thermal injuries were effectively avoided in 30 cases by using Leverage Displacement,while recurrent laryngeal nerve injuries happened in 2 cases using Hydrodissection for 29 nodules.The difference between these two methods on risk level Ⅲ had no statistical significance(P =0.237).To avoid thermal injuries during ablation for 109 nodules on risk level Ⅳ,using Leverage Displacement for 102 nodules,recurrent laryngeal nerve injuries happened in 1 case,while using Hydrodissection for 7 nodules,recurrent laryngeal nerve injuries happened in 2 cases.The difference between the two methods on risk level Ⅳ had statistical significance(P =0.010).No thermal injury happened during ablation for 143 nodules on risk level 0-Ⅱ.Conclusions Preoperative risk assessment on thyroid nodules is helpful in preventing potentially avoidable complications.Proper use of Leverage Displacement can protect adjacent vital structures from thermal injuries during ablation for nodules,which is easy and simple to handle and has a certain practical application value.

As the medical college students are scattered to each practice hospital, the status of the secondary clinical medical colleges' education management to interns is weakened, and the problems and contradictions are becoming increasingly prominent. In the process of internship education management, through the establishment of the secondary medical colleges' interconnection management working mecha-nism, we can effectively solve the outstanding problems in the current internship edu-cation management, to achieve mutual trust between the secondary clinical medical college and the training hospital, and en-hance the effectiveness of the management of interns.

Objective To study the immediate effect of applying a portable functional electrical stimulation device (PUEFESD) to the upper extremities of stroke patients.Methods Twenty stroke survivors were selected.Pairs of electrodes of the PUEFESD were applied on the dorsal and palm sides of the affected forearm and thenar to stimulate the extensors and flexors as well as the thenar muscles sequentially according to a programmed protocol.Functional evaluation was conducted before and immediately after the stimulation.All participants were assessed with regard to their motor function and performance in the activities of daily living using an upper extremity function test (UEFT),the upper extremity motor function portion of the Fugal-Meyer assessment (FMA),and rating with the modified Barthel index (MBI).A visual analogue scale (VAS) was used to evaluate pain in the affected upper extremity.Results The patients' average FMA score was 19.4 ± 7.1 before the stimulation and 30.4 ± 9.6 after.The corresponding UEFT scores were 3.6 ± 3.7 and 26.9 ± 5.9,and the average MBI scores were 53.8 ± 26.2 and 65.8 ± 17.7.All of these increases were statistically significant.The average VAS score,however,did not change significantly.Conclusions Functional electric stimulation can quickly improve upper extremity function and the ADL ability of stroke patients,but pain is not relieved significantly.

Objective To translate the Female Sexual Function Index(FSFI) into Chinese and establish its psychometric properties among ordinary Chinese people and diabetes patients.Methods A two-phase study design was applied.The Chinese version of FSFI was established by translation and back translation,then the reliability and validity of the FSFI were evaluated.Results The content validity coefficient of FSFI was 0.953.The test-retest reliability in each dimension had good correlations (r value was 0.817～0.922),with the highest correlation coefficient in vaginal lubrication dimension (0.922) and arousal dimension the minimum (0.817).In all samples (including diabetes and non diabetes) a reliability coefficients of the Cronbach alpha of each dimension was from 0.760 to 0.874.The Cronbach alpha of each dimension for the diabetic group was from 0.783 to 0.882,and from 0.757 to 0.865 in the non-diabetes group.Pearson correlation of each dimension was very good in total samples,the diabetes group,and the non-diabetes group.Conclusions The psychometric properties of the FSFI demonstrated satisfactory validity and reliability.The Chinese version of FSFI is a reliable and valid measure to evaluate the sexual function in Chinese women.
