Objective: To compare the effects of high intensity interval training (HIIT) exercise prescription based on machine vision and routine on HIIT the physical and mental health of female college students with simple obesity, so as to provide a basis for the development of weight loss intervention plans for this population. Methods: From August 2023 to February 2024, 115 female college students with simple obesity, selected from Lianyungang Vocational and Technical College and East China Normal University, were randomly divided into a control group ( n =57) and an observation group ( n =58) according to a random number table. The control group received routine HIIT, while the observation group received machine vision based on HIIT exercise prescription (including image acquisition module, image processing module, database management module, backend computer processing and feedback, intelligent evaluation module, which could be customized according to the subjects preferences, providing exercise prescription based on the selected training program and supervised its standardized completion of the training plan). Both were intervened for 12 weeks, 30 minutes each time, once every 2 days, and rest every Sunday. The t-test was used to compare body shape, glucose and lipid metabolism, cardiopulmonary function indicators, anxiety and depression states between two groups before and after intervention. Results: Before intervention, there were no statistically significant differences in physical and mental health status indicators between two groups of female college students ( t =0.13-0.86, all P >0.05). After intervention, body mass indexes, waist hip ratios, body fat percentage, fasting plasma glucose, 2hour postprandial plasma glucose, hemoglobin A1c, triglycerides, total cholesterol, lowdensity lipoprotein cholesterol (LDL-C), anxiety and depression scores were all reduced in both groups ( t-observation =-6.94 to -12.92, t-control =-2.71 to -10.95 ), of which the observation group [(23.46±2.18)kg/m 2, 0.70±0.06, (28.03±3.16)%, (4.55±0.67)mmol/L, (6.03±0.74)mmol/L, (5.10±0.70)%, (1.63±0.31)mmol/L, (4.24±0.58)mmol/L, (2.45±0.43)mmol/L, 35.28±4.76, and 33.03±4.03] were lower compared with the control group [(26.54±2.32)kg/m 2, 0.77±0.06, (30.74±4.38)%, (5.03±0.76)mmol/L, (6.62±0.82)mmol/L, (5.82±0.73)%, (1.98±0.35)mmol/L, (4.95±0.61)mmol/L, (2.88±0.47)mmol/L, 39.18±5.04, and 37.25±4.16] ( t =-7.34, -6.26 , -3.81, -3.59, -4.05, -5.40, -5.68, -6.40, -5.12, -4.27, -5.53)(all P <0.05). After intervention, high density lipoprotein cholesterol, stroke volume, left ventricular ejection fraction, maximum oxygen consumption, volume of tidal, and vital capacity increased in both groups ( t-observation =7.43-18.23, t-control =3.89-10.13), of which the observation group [(1.49±0.22)mmol/L, ( 72.35± 4.69)mL, (68.95±5.10)%, (36.97±3.22)mL/(kg ·( min), (25.29±4.11)mL/(kg · ( min), and (3 374.26±169.54)mL] were higher compared with the control group [(1.23±0.20)mmol/L, (67.32±4.06)mL, (64.83±5.05)%, (33.24±3.14)mL/(kg · ( min), (23.01± 3.58 )mL/(kg · ( min), and (3 197.50±125.81)mL] ( t =6.63, 6.15, 4.35, 6.29, 3.17, 6.34)(all P <0.05). Conclusion HIIT exercise prescription based on machine vision has better effects than routine HIIT on impoving the body shape, glucose and lipid metabolism, cardiopulmonary function of female college students with simple obesity, and also their mental health.

OBJECTIVE To evaluate the global cancer-associated thromboembolism risk assessment tools based on evidence- based methods， and to provide methodological reference and evidence-based basis for constructing a specific tool in China. METHODS A comprehensive search was conducted on 6 databases， including CNKI， Wanfang data， VIP， CBM， PubMed， and Embase， as well as on the websites of NCCN， ASCO， ESMO and so on with a deadline of June 30， 2022. Furthermore， a supplementary search was conducted in January 2023. The essential characteristics and methodological quality of included risk assessment tools were described and analyzed qualitatively， focusing on comparing each assessment stratification ability. RESULTS Totally 14 risk assessment tools were included in the study， with a sample size of 208-18 956 cases and an average age distribution of 53.1-74.0 years. The applicable population included outpatient cancer student@sina.com patients， lymphoma patients， and multiple myeloma patients，etc. The common predictive factors were body mass index， venous thromboembolism history， and tumor site. All tools had undergone methodological validation， with 9 presented in a weighted scoring format. Only seven tools were used simultaneously for specificity， sensitivity， negative predictive value （NPV）， positive predictive value （PPV） and area under the curve （AUC） or C statistical analysis. CONCLUSIONS The risk of bias in constructing existing tools is high， and the heterogeneity of tool validation results is significant. The overall methodological quality must be improved， and its risk stratification ability must also be investigated. There are still certain limitations in clinical practice in China.

Objectives:To evaluate the valvular and cardiac function,cardiac reverse remodeling at 6-month after transcatheter edge-to-edge repair(TEER)for patients with functional and degenerative mitral valve regurgitation,and summarize the experience of echocardiography application. Methods:The clinical data of 93 patients with moderate to severe mitral regurgitation(MR)treated with TEER and completed 6-month follow-up in Yunnan Fuwai Cardiovascular Hospital from July 2022 to February 2023 were retrospectively analyzed.Patients were divided into functional mitral regurgitation(FMR)and degenerative mitral regurgitation(DMR)groups according to MR etiology.The valve characteristic parameters,as well as valvular function,chamber volume and cardiac functional parameters before and at 6 months after operation were compared.The key points of echocardiography application were summarized. Results:Among all patients,71 were FMR and 22 were DMR.There were differences in valve structure between the two groups.Mitral TEER were successfully accomplished and all patients completed 6-month follow-up.The key points of echocardiography application included:valve structure analysis,atrial septal puncture location,device delivery process monitoring and image optimization during clamping process.The mitral regurgitation grade and NYHA grade were significantly improved in all patients at 6 months after TEER(P<0.05),and the mean mitral valve pressure gradient was higher than that before operation(P<0.05).Left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV)and left atrial volume index in FMR group were significantly decreased(P<0.05),while left ventricular and left atrial volume in DMR group remained unchanged(P>0.05).There were no significant changes in left ventricular ejection fraction and left ventricular global strain in both groups during the observation period(P>0.05).The changes of LVEDV and LVESV before and after operation were more significant in FMR group than those in DMR group(P<0.05). Conclusions:Mitral TEER can reduce the degree of regurgitation and improve cardiac function in the early postoperative period for moderate and severe MR patients with different etiologies.There are differences in preoperative valve structure and postoperative cardiac reverse remodeling between FMR and DMR patients.Echocardiography is an important imaging technique for the evaluation and monitoring process before,during and post mitral TEER.

ObjectiveTo analyze the epidemiological characteristics of hand, foot, and mouth disease (HFMD) in Zhangjiakou City, Hebei Province from 2013 to 2022, so as to provide a basis for HFMD prevention, control, and evaluation of intervention effectiveness. MethodsHFMD data of Zhangjiakou City from 2013 to 2022 were collected. Descriptive statistics and the Joinpoint regression model were used to analyze the trend of the epidemic. ResultsThe incidence of HFMD in Zhangjiakou was predicted to decrease with APC=-14.86% in 2013‒2022. The top five regions with the highest incidence showed varying trends: Qiaodong District (APC=-26.21%), Qiaoxi District (APC=-18.29%), Xuanhua District (APC=-14.28%), Chicheng District (APC=-18.68%), and Zhuolu County (APC=51.43% in 2013‒2016, APC=-14.27% in 2016‒2022), indicating a downward trend. Three age groups showed an upward trend in incidence: the 0-year-old group (APC=-42.82% in 2013‒2016, APC=16.54% in 2016‒2022), the 7-year-old group (AAPC=9.60%), and the 9-year-old group (AAPC=12.76%). HFMD cases occurred throughout the year, peaking from June to August, with July being the most significant month. The male-to-female ratio was1.40∶1, with no statistical difference (χ²=5.932, P>0.05). A high incidence was in children under 5 years old, with those aged 1‒4 years being the main affected group. In terms of occupation, scattered children (6 245 cases, 57.65%) and preschool children (3 653 cases, 33.72%) were the most affected. A total of 504 laboratory-confirmed cases were reported, with a detection rate of 4.65% (504/10 832). The composition of confirmed cases included CoxA 16 (193 cases, 38.29%), EV71 (75 cases, 14.88%), and other enteroviruses (236 cases, 46.83%). ConclusionFrom 2013 to 2022, HFMD in Zhangjiakou City showed a downward trend with clear seasonal, regional, and occupational distributions. It is suggested that epidemic monitoring should be strengthened, etiological detection should be enhanced, and education efforts in key areas should be improved. High-incidence counties should analyze data and conduct risk assessments effectively.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective To explore the reliability and safety of continuous monitoring of vital signs in patients using wireless wearable monitoring devices after video-assisted thoracoscopic surgery (VATS) for lung cancer. Methods The patients undergoing VATS for lung cancer in West China Hospital, Sichuan University from May to August 2023 were prospectively enrolled. Both wireless wearable and traditional wired devices were used to monitor the vital signs of patients after surgery. Spearman correlation analysis, paired sample t test and ratio Bland-Altman method were used to test the correlation, difference and consistency of monitoring data measured by the two devices. The effective monitoring rate of the wireless wearable device within 12 hours was calculated to test the reliability of its continuous monitoring. Results A total of 20 patients were enrolled, including 15 females and 5 males with an average age of 46.20±11.52 years. Data collected by the two monitoring devices were significantly correlated (P<0.001). Respiratory rate and blood oxygen saturation data collected by the two devices showed no statistical difference (P>0.05), while heart rate measured by wireless wearable device was slightly lower (=−0.307±1.073, P<0.001), and the blood pressure (=1.259±5.354, P<0.001) and body temperature(=0.115±0.231, P<0.001) were slightly higher. The mean ratios of heart rate, respiratory rate, blood oxygen saturation, blood pressure and body temperature collected by the two devices were 0.996, 1.004, 1.000, 1.014, and 1.003, respectively. The 95% limits of agreement (LoA) and 95% confidence interval of 95%LoA of each indicator were within the clinically acceptable limit. The effective monitoring rate of each vital signs within 12 hours was above 98%. Conclusion The wireless wearable device has a high accuracy and reliability for continuous monitoring vital signs of patients after VATS for lung cancer, which provides a security guarantee for subsequent large-scale clinical application and further research.
