Therapeutic effect of different treatment methods on functional anorectal pain

Objective： To observe the clinical efficacy of oral traditional Chinese medicine （Jiaweitiaoqi decoction）, electroacupuncture, biofeedback, and combined treatment on functional anorectal pain （FAP）. Methods： A total of 200 patients with FAP were randomly divided into 4 groups, with 50 patients in each group. Group 1 was given oral Jiaweitiaoqi decoction; group 2 was given electroacupuncture at the lumbosacral acupoints; group 3 was given biofeedback training; and group 4 was given combined treatment. The numeric rating scale （NRS）, Short Form-36 （SF-36） quality of life scale, static pressure of the anal canal, and maximum systolic pressure were observed in the 4 groups. Results： The observation indices of the 4 groups were all improved after treatment compared with those before treatment, and the fourth group showed the most obvious improvement. Regarding NRS scores, the static pressure of the anal canal, and maximum systolic pressure, group 4 had lower values than the other 3 groups （P 〈 0.05 for all）. In the SF-36 quality of life score, group 4 showed a higher value than the other 3 groups （P 〈 0.05）. Conclusion： Non-drug therapy including acupuncture and physical exercise can enhance the clinical efficacy of single Chinese medicine in the treatment of FAP .

NonliNonlinear GPC with In-place Trained RLS-SVM Model for DOC Control in a Fed-batch Bioreactor

In this study, Saccharomyces cerevisiae (baker's yeast) was produced in a fed-batch bioreactor at the optimal dissolved oxygen concentration (DOC) and growth medium temperature. However, it is very difficult to control the DOC using conventional controllers because of the poorly understood and constantly changing dynamics of the bioprocess. A generalized predictive controller (GPC) based on a nonlinear autoregressive integrated moving average exogenous (NARIMAX) model is presented to stabilize the DOC by manipulation of air flow rate. The NARIMAX model is built by an improved recursive least-squares support vector machine, which is trained by an in-place computation scheme and avoids the computation of the inverse of a large matrix and memory reallocation. The proposed nonlinear GPC algorithm requires little preliminary knowledge of the fermentation process, and directly obtains the nonlinear model in matrix form by using iterative multiple modeling instead of linearization at each sampling period. By application of an on-line bioreactor control, experimental results demonstrate the robustness, effectiveness and advantages of the new controller.

Metabolic response to 6-week aerobic exercise training and dieting in previously sedentary overweight and obese pre-menopausal women:A randomized trial

Background： The aim of this study was to compare 6 weeks short-term moderate intensity aerobic exercise and dieting on serum metabolomics and cardio-metabolic risk factors in pre-menopausal women. Methods： Ninety previously inactive overweight and obese （BMI 25-35 kg/m2） women （age 41.5 ± 7.6 years） were randomized to either a 6-week Nordic walking exercise program （EX, n = 45） or dietary counseling group （DI, n = 45）. Body composition, serum glucose, insulin and lipids were measured. Serum low-molecular-weight metabolites and lipid constituents were analyzed by nuclear magnetic resonance spectroscopy. Measurements were done at baseline and 7 days after the last training session. Results： Six weeks aerobic exercise program yielded reductions in serum free fatty acids （-34.7%, 95% confidence interval （CI）, -50 to -18, p 〈 0.001）, glucose （-9.6%, 95%CI, -15 to -4, p 〈 0.001） and homeostasis model assessment of insulin resistance （HOMA-IR） （-28.7%, 95%CI, -48 to -10, p = 0.005） without changes in body weight or fat mass. Diet counseling resulted in loss of body weight （1.5%, 95%CI, -2.3 to -0.7, p = 0.001） but no changes in free fatty acids, fasting glucose, or HOMA-IR were found. Conclusion： Our results indicate that small weight loss does not produce measurable health benefits, whereas short-term regular aerobic exercise can improve glucose and lipid metabolism even in the absence of weight loss in previously sedentary overweight and obese women.

Changes in balance ability,power output,and stretch-shortening cycle utilisation after two high-intensity intermittent training protocols in endurance runners

Purpose：This study aimed to describe the acute effects of 2 different high-intensity intermittent trainings（HIITs） on postural control,countermovement jump（CMJ）,squat jump（SJ）,and stretch-shortening cycle（SSC） utilisation,and to compare the changes induced by both protocols in those variables in endurance runners.Methods：Eighteen recreationally trained endurance runners participated in this study and were tested on 2 occasions：10 runs of 400 m with 90 s recovery between running bouts（10×400 m）,and 40 runs of 100 m with 30 s recovery between runs（40 × 100 m）.Heart rate was monitored during both HIITs;blood lactate accumulation and rate of perceived exertion were recorded after both protocols.Vertical jump ability（CMJ and SJ） and SSC together with postural control were also controlled during both HIITs.Results：Repeated measures analysis revealed a significan improvement in CMJ and SJ during 10 × 400 m（p〈0.05）,whilst no significan changes were observed during 40×100 m.Indexes related to SSC did not experience significan changes during any of the protocols.As for postural control,no significan changes were observed in the 40×100 m protocol,whilst significan impairments were observed during the 10×400 m protocol（p〈0.05）.Conclusion：A protocol with a higher number of shorter runs（40×100 m） induced different changes in those neuromuscular parameters than those with fewer and longer runs（10×400 m）.Whereas the 40×100 m protocol did not cause any significan changes in vertical jump ability,postural control or SSC utilisation,the 10×400 m protocol impaired postural control and caused improvements in vertical jumping tests.

Adaptive Nonlinear Model Predictive Control Using an On-line Support Vector Regression Updating Strategy

The performance of data-driven models relies heavily on the amount and quality of training samples, so it might deteriorate significantly in the regions where samples are scarce. The objective of this paper is to develop an online SVR model updating strategy to track the change in the process characteristics efficiently with affordable computational burden. This is achieved by adding a new sample that violates the Karush–Kuhn–Tucker conditions of the existing SVR model and by deleting the old sample that has the maximum distance with respect to the newly added sample in feature space. The benefits offered by such an updating strategy are exploited to develop an adaptive model-based control scheme, where model updating and control task perform alternately.The effectiveness of the adaptive controller is demonstrated by simulation study on a continuous stirred tank reactor. The results reveal that the adaptive MPC scheme outperforms its non-adaptive counterpart for largemagnitude set point changes and variations in process parameters.

Quantifying Neuromuscular Electrical Stimulation Dosage after Knee Arthroplasty

Recovering functional ability after total knee arthroplasty （TKA） requires recovery of strength and voluntary activation. Short-term recovery of strength and activation are enhanced following a protocol combining strength training with neuromuscular electrical stimulation （NMES）. The purpose of the study was to determine if a dose response curve could be constructed for patients who received NMES as part of their treatment after TKA. NMES dosage was quantified as the electrically evoked knee extensor torque, expressed as a percentage of the subject＇s maximal voluntary contraction. Dose-response curves were generated, with the associations between NMES training intensity and quadriceps strength, voluntary activation, and lean muscle cross-sectional area examined using Pearson Product-Moment Correlation Coefficients. Significantly, linear correlations were observed between NMES training intensity and both quadriceps strength and voluntary activation, but not lean muscle cross-sectional area. These results suggest that maximizing the elicited training force during rehabilitation will enhance short-term recovery following TKA.

The Impact of Developing Coordination Abilities on the Skill Abilities for Table Tennis Iuniors

The coordination abilities are closely related to the development of technical motor skills, where the player cannot master the technical skills in the special activity, in case lack of special coordination abilities for this activity. Many of table tennis experts agree on that the special coordination abilities for table tennis include each of： （1） the motor adaptation and adjustment ability; （2） the ability to differentiate; （3） reaction speed ability; （4） orientation ability; （5） balance ability; （6） coupling ability; and （7） the ability to sense the rhythm. The aim of this study is to design a training program to develop the special coordination abilities of table tennis and identify the impact of this program on the general skill ability for table tennis juniors. The researcher used the experimental method in two groups： One group is experimental group and another is the control group. The most important result of this study was the training program led to the improvement of the special coordination abilities of table tennis for the experimental group, which led to higher levels of the general skill ability in table tennis for the experimental group more than the control group.
