Non-drug treatment of hypertension has become a research hotspot, which might overcome the heavy economic burden and side effects of drug treatment for the patients. Because of the good treatment effect and convenient operation, a new treatment based on slow breathing training is increasingly becoming a kind of physical therapy for hypertension. This paper explains the principle of hypertension treatment based on slow breathing training method, and introduces the overall structure of the portable blood pressure controlling instrument, including breathing detection circuit, the core control module, audio module, memory module and man-machine interaction module. We give a brief introduction to the instrument and the software in this paper. The prototype testing results showed that the treatment had a significant effect on controlling the blood pressure.
ObjectiveTo systematically review the intervention effects of high-intensity interval training (HIIT) on weight loss and blood lipid metabolism in overweight/obese populations. MethodsThe computer conducted searches in the PubMed, Embase, Cochrane Library, Web of Science, CNKI, and WanFang Data database to collect randomized controlled trials (RCTs) related to HIIT and weight loss, fat reduction, and blood lipid metabolism in overweight/obese populations. The search was conducted from the inception of the databases to March 31, 2023. Two researchers independently conducted literature screening and data extraction. After evaluating the risk of bias of the included studies, a meta-analysis was performed using RevMan 5.4 software. ResultsA total of 19 RCTs, involving 595 overweight/obese participants, were included. The meta-analysis results showed that compared wtih the control group, HIIT interventions effectively reduced body weight (MD=−2.63, 95%CI −4.04 to −1.23, P<0.05), BMI (MD=−1.21, 95%CI −1.95 to −0.48, P<0.05), Fat% (MD=−1.66, 95%CI −2.28 to −1.04, P<0.05), TG (MD=−0.13, 95%CI −0.25 to −0.01, P=0.04), HDL (MD=0.14, 95%CI 0.05 to 0.23, P<0.05), and LDL (MD=−0.26, 95%CI −0.39 to −0.13, P<0.05) levels but did not improve TC (MD=−0.15, 95%CI −0.36 to 0.06, P=0.15) levels. ConclusionHIIT intervention can effectively improve body weight, BMI, Fat%, TG, HDL, and LDL levels in overweight/obese populations, particularly showing a more pronounced improvement in lipid profiles among overweight/obese adolescents, but it does not reduce TC levels. This study demonstrates that HIIT may be an effective strategy to assist in weight loss and prevent cardiovascular diseases in overweight/obese populations, with potential for broader application.
Objective To investigate the effects of repeated shortischemia training on flap survival area, vascular endothelial growth factor and the microvascularsel density. Methods Seventy-two rabbits were divided into:the experimental group(n=64), the skin flaps were constructed in two sides of back, one side flap were given ischemia training for 15 minutes and 8 times one day at the pedicles from the 1st to 8th day after operation (group A), the other side flap was served as a control (group B), the corresponding site was only marked as a blank control group (group C).Then, 8 pedicles of group A and group Bwere isolated every day. The surviving area of all skin flaps were calculated on the5th day after isolating operation. The vascular endothelial growth factor(VEGF)and microvessel density(MVD) of the 3 groups were checked with immunohistologochemical staining. Results After the operation, all animalswere survival with normal vitality.The survival flap area of group A were significant more than that of group B after 3 days(Plt;0.05).The expressions of VEGF and MVD of group A and group B were higher than group C. The expression of VEGF of group A was significantly higher than that of group B(Plt;0.01). The counting of MVD of group A was also significantly higher than that of group B(Plt;0.05). There was positive correlation between flap survival area and MVD in group A. The relation of time point was n and n 2 respectively,correlation coefficient was 0.850. As well as MVD and VEGF were positive correlation,correlation coefficient was 0.801. Conclusion Early repeated shortischemia training can increase flap survival area, the mechanism maybe involve the increased expression of VEGF, which can increased skin flap microvascular density.
Objective To explore the difference of intervention effect between high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on patients with metabolic syndrome (MetS). Methods China National Knowledge Infrastructure, WanFang Data, PubMed, Web of Science and EBSCO were searched for randomized controlled trials (RCTs) till May 2022. Two reviewers independently reviewed the literature, extracted data, and assessed the risk of bias of included RCTs. Comprehensive Meta-Analysis software was used for meta-analysis. Result A total of 5 RCTs were included, including 216 patients. The results of meta-analysis showed that: except fasting blood glucose, high-density lipoprotein cholesterol, systolic blood pressure, waist circumference, body mass index and body fat percentage (P>0.005), low-density lipoprotein cholesterol [mean difference (MD)=−7.487 mg/dL, 95% confidence interval (CI) (−12.543, −2.431) mg/dL, P=0.004], total cholesterol [MD=−11.487 mg/dL, 95%CI (−16.523, −6.452) mg/dL, P<0.001], triglycerides [MD=−26.296 mg/dL, 95%CI (−50.557, −2.035) mg/dL, P=0.034] and diastolic blood pressure [MD=−2.770 mm Hg (1 mm Hg=0.133 kPa), 95%CI (−5.131, −0.409) mm Hg, P=0.021] of HIIT were better than MICT. Conclusion In terms of blood glucose indicators and morphological indicators, the effect of HIIT group and MICT group was similar, but the effect of HIIT on blood lipid indicators and blood pressure indicators of patients with MetS was better than MICT.
The ideological and political education in standardized residency training plays an important role in cultivating medical talents with noble medical ethics and exquisite medical skills. Teaching evaluation is an important method to promote teaching improvement and optimization. However, there are still some problems and challenges in the evaluation of ideological and political education for standardized residency training. This article proposes the ideological and political education of standardized residency training can be comprehensively evaluated by the context-input-process-product evaluation model from four aspects: background, input, process, and result evaluation. The aim is to provide solid support and guidance for the ideological and political education route in standardized residency training.
Objective To investigate and explore the clinical effect of preoperative exercise intervention on total hip arthroplasty. Methods Seventy-three patients who underwent primary unilateral total hip replacement (THR) in the Orthopedics Department, the Second Hospital of Jilin University between March 2017 and January 2018 were divided into 2 groups: treatment group (n=37) and control group (n=36). Patients in treatment group received exercise intervention and routine education since 4 weeks before surgery; the control group just received routine education before surgery and both groups underwent the same routine rehabilitation training. The Visual Analogue Scale (VAS) was evaluated and compared separately between the two groups at 4 weeks before surgery (T0), 1 day before surgery (T1), before discharge (T2), 1 month after discharge (T3), and 3 months after discharge (T4). The results of Hip Harris score and Time Up and Go test (TUG) were evaluated and compared separately between the two groups at T0, T1, T3 and T4. Results Time of TUG of the treatment group and the control group at T1, T3 and T4 were (14.59±3.15) vs. (16.31±3.31) s, (13.61±2.76)vs. (15.25±3.08) s, (12.49±2.37)vs. (14.22±2.65) s, respectively, and the differences between the two groups at T1, T3 and T4 were all statistically significant (P<0.05). In terms of VAS and Harris scores, both groups showed significant improvement after surgery at different time nodes (P<0.05), but the differences between the two groups was not statistically significant (P>0.05). Conclusion Preoperative exercise intervention can effectively improve the walking ability of THR patients and reduce the risk of falls after discharge, but it did not reduce postoperative pain or improve postoperative hip Harris score after discharge.
ObjectiveTo compare whether the training process of commissioned training residents from Tibet and non-commissioned training residents have achieved homogenized.MethodsThe training time and operation frequency data of 170 commissioned training residents from Tibet and 96 non-commissioned training residents of grade 2016 during the 19 months from September 2016 to April 2018 were collected. The 25 operational data of 11 departments that are representative and comparable are compared.ResultsThe two types of trainees completed the rotation of 47 different departments within 19 months, of which 45 departments were the departments where both types of students were rotated. Among these 11 departments, the average training time of trainees from Tibet in the Departments of Anesthesiology was lower than that of non-commissioned trainees (Z=–4.543, P<0.001). There were statistically significant differences in 7 of the 25 operating data (P<0.05). The operation number of arterial puncture and ventilator management (Intensive Care Unit); patient treatment (Department of Emergency); arterial puncture, ventilator management and intraoperative monitoring (Department of Anesthesiology) of trainees from Tibet were lower than those of non-commissioned trainees (P<0.05). The operation number of lung and mediastinal examinations (Department of Radiology) of trainees from Tibet was higher than that of non-commissioned trainees (P<0.05).ConclusionsDuring the training of the two types of trainees, the rotation schedule was basically the same, but there were differences in the clinical practice operations. Trainees from Tibet have higher requirements for radiology training. Trainees from Tibet will return to Tibet with independent practice needs, so their requirements of medical imaging skills operation would be higher. Due to language and training time, the critically ill, emergency first aid, and surgical skills of trainees from Tibet are not as good as those of non-commissioned trainees, and they need to gradually strengthen and improve these skills in subsequent trainings.
According to the "Regulations on clinical application management of medical technologies", physicians intending to carry out restricted technologies must undergo standardized training and pass assessments in accordance with the clinical application management standards for the respective technology. As ventricular assist technology is classified as a nationally restricted technology, standardized training is one of the essential conditions for its application. This paper primarily explores the standardized training for the clinical application of ventricular assist technology in Shanghai, in light of its background, clinical application, and current training status. It proposes the training requirements for ventricular assist technology, animal training assessment standards, and clinical practice assessment standards in Shanghai, aiming to promote the standardized development and high-quality advancement of ventricular assist technology in Shanghai.

This article mainly elaborates on the problems in the current residents teachers training, the “coordination of six priorities” teachers training system of West China Hospital of Sichuan University, and the effect of the teachers training.
Objective To provide scientific evidence for the establishment of medical specialist system in China by analyzing the current situation and problems, putting forward solution thoughts and countermeasures, from the angle of medical education system, residency training program and licensed physician management. Method Principle and method of evidence-based medicine were adopted. Retrospective investigation was conducted to gain information from 1996 to 2002 about enrollment and running form of medical education, current situation of residency and specialist training. Data was then extracted and analyzed for the benefit of corresponding countermeasures. Results By the end of 2001, there were totally 1 640 thousand physicians in China. The enrollment proportion of undergraduate and junior college student steadily increased from 1996 to 2002, while the situation quite the reverse as for medical secondary school. More than 300 thousand have taken part in the licensure exam, among whom less than 15% had university diploma. About 52 000 doctors have already completed the residency training program, and 65 700 are being trained. Standardized system of specialist training and admittance is not available in China. Conclusions It was three main tough problems that mainly account for the poor quality of doctor as a whole in China, which include diversity of educational system, insufficient software and hardware of residency training program, and absence of specialist training system. An allied funded program of "research on medical specialist training and admittance" has been on the way, and research outcomes will be published soon.
