This research is to develop a weight-loss walking rehabilitation training system based on differential air pressure. The system adopted Proportion-Integral-Derivative (PID) algorithm to improve the precision of weight loss, taking MSP430F149 microprocessor of Texas Instruments as the core of pressure control system. The training software is designed based on Microsoft Visual C++ 6.0 of Microsoft. The system can provide comfortable training environment for patients with lower limb motor function impediment, and can collect electromyographic signals from patients, so as to further the scientific and normative management of the patient's information. Based on this training system, the initial bearing weight, bearing weight after maximum weight loss, and maximum weight loss percentage of 10 normal adults’ lower limbs were collected. It was found that the intraclass correlation coefficient (ICC) values were all greater than 0.6. The training system has a good reliability, which can provide scientific data for clinical weight-loss lower limb rehabilitation training.
Objective To explore the effect of different intensity treadmill training on the repair of micro-injured Achilles tendon induced by collagenase in rats. Methods Seventy-two 8-week-old male Sprague Dawley rats (weighing, 200-250 g) were selected. After adaptive treadmill training for 1 week, rats were injected with 30 μL type I collagenase solution (10 mg/mL) into both Achilles tendons to make micro-injured Achilles tendon models. After 1 week of cage feeding, the rats were randomly divided into 3 groups: the control group, the low-intensity group, and the high-intensity group, 24 rats each group. The rats in control group could move freely, and the rats underwent daily treadmill training at the intensity of 13 m/min and 20 min/d in the low-intensity group and at the intensity of 17 m/min and 60 min/d in the high-intensity group. At immediate, 1 week, and 4 weeks after training, bilateral Achilles tendons were collected from 8 rats of each group for gross observation, histological analysis, and mechanical testing. Results At immediate after training, there was no significant difference in the gross observation, histological observation, and biomechanical properties of the Achilles tendon between groups (P>0.05). The gross observation showed connective tissue hyperplasia near Achilles tendon and lackluster tendon in each group at 1 week; hyperplasia significantly reduced in the low-intensity group when compared with the control group, and there were more connective tissue and a large number of neovascularization in the high-intensity group at 4 weeks. At 1 week, there was no significant difference in the semi-quantitative histological total score between groups (P>0.05), but there were significant differences in vascularity between low-intensity group or high-intensity group and control group (P<0.05). At 4 weeks, the semi-quantitative histological total score was significantly higher in high-intensity group than control group and low-intensity group (P<0.05), and in control group than low-intensity group (P<0.05). There were significant differences in collagen arrangement, cell morphology, abnormal cells, and vascularity between low-intensity group and high-intensity group or control group (P<0.05). And there was significant difference in abnormal cells between high-intensity group and control group (P<0.05). The mechanical testing showed that there was no significant difference in cross-sectional area of the Achilles tendon, the ultimate force, tensile strength, and elastic modulus between groups at 1 week (P>0.05); the low-intensity group was significantly higher than the control group in the ultimate force and the tensile strength (P<0.05), and than high-intensity group in the ultimate force and elastic modulus (P<0.05), but no significant difference was found in the other indexes between groups (P>0.05) at 4 weeks. Conclusion Low-intensity treadmill training can promote the repair of rat micro-injured Achilles tendon induced by collagenase.
Tricuspid valve, also known as "forgotten valve" because of the high natural and surgical mortality. Transcatheter tricuspid valve replacement is an innovative surgical method to treat tricuspid regurgitation, which improves the prognosis of patients and is gradually being popularized in clinics. However, postoperative pulmonary complications are still the main causes affecting the rapid recovery and death. More and more medical experts begin to use preoperative inspiratory muscle training to reduce postoperative pulmonary complications and improve the quality of life of patients after cardiac surgery. However, there was no report on the effect of preoperative inspiratory muscle training on pulmonary complications after transcatheter tricuspid valve replacement. Therefore, for the first time, we boldly speculate that inspiratory muscle training can reduce pulmonary complications after transcatheter tricuspid valve replacement, and put forward suggestions for its treatment mechanism and strategy. But this rehabilitation intervention lacks practical clinical research. Unknown challenges may also be encountered, which may be a new research direction.
Objective To provide scientific evidence for the establishment of medical specialist system in China by investigating the history, current situation, problems and countermeasures of medical specialties training at home and aboard. Method The principle and theroy of evidence-based medicine were adopted. The information before Dec. 31, 2003 of Pubmed, CBM, official website, some journals, most frequently used search engines and medical monograph were systematically reviewed. Included literatures were assessed and graded according to the pre-defined criterias. Results A total of 1 319 studies (1 298 in English, 21 in Chinese) were included, among which only 6 were related to the classification of medical specialties. Based on the information from official website of USA, Canada, UK, Singapore, Australia and China (including HK and Taiwan), it showed that China has the largest number of medical specialties, followed by that of USA. In China, the number of medical specialties has more than that of the disciplines in clinical field, which was followed by resident training programs. Some specialties were duplicate, or not international standardized. Conclusions The classification of medical specialties should be developed consecutively, which comprehensively considered the international trend, characteristics of doctor training and the current situation. Specialties whose training program are well-established and developed should initiate firstly. Others will be put into practice gradually after being fully exprienced.

The prevalence of developmental delay (DD) in children worldwide is still on the rise, and its causes are complex and diverse, causing varying degrees of impact on the development of the sensory nervous system in the brain of children. Sensory integration training is a treatment method that applies sensory stimulation and comprehensive activities. It is currently widely used in children with DD. This therapy can effectively improve the development and integration of the sensory system in children with DD. It also enhances the individual’s ability to adapt to external stimuli, promoting their development in language, motor, and cognitive functions. This article explores the relevant mechanisms of sensory integration training and DD, as well as the current status and effects of its application in DD children, in order to promote the development and progress of related research fields.
Objective To systematically review the rehabilitation effect of isokinetic muscle training on knee muscle strength, functional walking ability and dynamic balance in post-stroke patients. Methods PubMed, Ovid Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Chongqing VIP, and Wanfang databases were searched online for randomized controlled trials on isokinetic muscle training of lower limbs in post-stroke patients. The retrieval time was from inception to October, 2022. Endnote X9 software was used to manage the literature. Cochrane Manual 5.1.0 was used for quality assessment, and RevMan 5.4 software was used for meta-analysis. Results A total of 20 randomized controlled trials were included in the study, with the intervention group using isokinetic muscle training of the lower extremities or combined with conventional rehabilitation training and the control group using conventional rehabilitation training and/or other intervention, with a total of 1448 study subjects. Meta-analysis results showed that the differences in knee flexion peak torque [mean difference (MD)=5.85 N·m, 95% confidence interval (CI) (4.84, 6.85) N·m, P<0.00001], knee extension peak torque [MD=9.09 N·m, 95%CI (4.83, 13.36) N·m, P<0.0001], Time Up Go test [MD=–4.70 s, 95%CI (–6.68, –2.72) s, P<0.00001], 10-meter walking test [MD=–4.71 s, 95%CI (–9.12, –0.31) s, P=0.04], Fugl-Meyer Lower Extremity Motor Function Assessment score [MD=6.61, 95%CI (3.52, 9.70), P<0.0001], and Berg Balance Scale score [MD=5.61, 95%CI (0.91, 10.31), P=0.02] were statistically significant. Conclusion Isokinetic training may improve knee strength and functional walking ability in post-stroke patients, but there is still no strong evidence of improvement in motor function and balance.
Although the current postgraduate education system is gradually improving, there are still some problems in the education mode of postgraduate, especially medical postgraduates in China. The current education mode lacks the ability to stimulate students’ potential to the greatest extent and cultivate talents who can develop comprehensively and focus on a certain direction, and lacks the ability to cultivate “four-faceted” scientific and technological workers who can advance to the breadth and depth of science. In view of the above problems, this paper explores the postgraduate education mode based on the close clinical-basic medicine combination on the basis of the tutor system, and summarizes the successful experience obtained in the process of practical teaching, aiming to provide a high quality reference for the medical postgraduate education.
Objective To investigate the effectiveness of double EndoButton suture fixation Latarjet procedure in the treatment of shoulder anterior dislocation with glenoid bone defect caused by military training injuries.MethodsThe clinical data of 14 patients with anterior shoulder dislocation with glenoid bone defect due to military training injuries who met the selection criteria and admitted between August 2021 and December 2022 were retrospectively analyzed. All patients were male, the age ranged from 21 to 38 years, with an average of 26.8 years. The time from initial dislocation to operation was 6-15 months, with an average of 10.2 months. Anterior shoulder dislocation occurred 5-12 times, with an average of 8.2 times. All glenoid bone defects were more than 10%, including 5 cases of 10%-15%, 8 cases of 15%-20%, and 1 case of 24%. All patients were treated by double EndoButton suture fixation Latarjet procedure. The operation time and complications were recorded. The shoulder function and pain were evaluated by the American Association for Shoulder and Elbow Surgery (ASES) score, Rowe score, Instability Severity Index Score (ISIS), and visual analogue scale (VAS) score before and after operation. The range of motion of the shoulder was recorded, including forward flexion, 0° external rotation, and abduction 90° external rotation. The position, healing, and resorption of the bone mass were evaluated by three-dimensional CT of shoulder joint after operation. Results All patients successfully completed the operation, and the operation time was 100-150 minutes, with an average of 119.7 minutes. There was no complications such as infection, vascular and nerve injury. All patients were followed up 12-20 months, with an average of 15.6 months. During the follow-up, 4 patients had bone mass separation, absorption, and recurrent anterior dislocation, and the shoulder joint fear test was positive. Imaging of the remaining patients showed that the bone mass healed well, no anterior dislocation recurrence occurred, and the healing time was 3-7 months (mean, 4.7 months). At last follow-up, the range of motion, ASES score, Rowe score, ISIS score, and VAS score of the patients significantly improved when compared with those before operation (P<0.05). ConclusionThe effectiveness of double EndoButton suture fixation Latarjet procedure for the treatment of anterior shoulder dislocation with glenoid bone defect caused by military training injury is satisfactory.
