BACKGROUND: As an essential part of health services, rehabilitation is of great significance to improve the health and quality of life of the whole population. Accelerating aging calls for a significant expansion of rehabilitation services in China, but rehabilitation needs remain unclear. We conducted the study to explore the rehabilitation needs in China and project the trend of rehabilitation needs from 2020 to 2034. METHODS: The data of health conditions that might potentially benefit from rehabilitation were obtained from Global Burden of Disease (GBD) study. Estimated annual percentage changes (EAPCs) were calculated to quantify the trends of the age-standardized rates. Projections of rehabilitation needs were made until 2034 using Bayesian age-period-cohort analysis (BAPC). RESULTS: Approximately 460 million persons (33.3% of the total population) need rehabilitation in China, contributing to 63 million years lived with disabilities (YLDs) in 2019. The number of prevalent cases that need rehabilitation increased from around 268 (95% uncertainty interval [UI]: 257-282) million in 1990 to almost 460 (95% UI: 443-479) million in 2019, representing an increase of 71.3%. The highest contribution to the need for rehabilitation was musculoskeletal disorders with about 322 (95% UI: 302-343) million persons in seven aggregate disease and injury categories, and hearing loss with over 95 (95% UI: 84-107) million people among 25 health conditions. Based on the projection results, there will be almost 636 million people (45% of the total population) needing rehabilitation services in China by 2034, representing an increase of 38.3%. The rehabilitation needs of neoplasms, cardiovascular diseases, and neurological disorders are expected to increase significantly from 2019 to 2034, with increases of 102.3%, 88.8% and 73.2%, respectively. CONCLUSIONS The need for rehabilitation in China substantially increased over the last 30 years. It is predicted that over two in five people will require rehabilitation by 2034, thus suggesting the need to develop rehabilitation services that meet individuals' rehabilitation needs.

Objective:To characterize the epidemiological features of hemorrhagic fever with renal syndrome (HFRS) in Jixi region, Heilongjiang Province, and to develop an autoregressive integrated moving average (ARIMA) model to predict the incidence trend of HFRS, thus to provide a scientific basis for targeted prevention and control.Methods:HFRS case data and host animals surveillance data from January 2013 to December 2024 in Jixi City were collected. Descriptive epidemiological methods were used to analyze the temporal, spatial, and population distribution characteristics of HFRS, with comparisons made using the chi-square test. ArcGIS10.8.2 software was employed for spatial clustering analysis. Moran I was used to assess the overall spatial trend of HFRS incidence. Getis-Ord Gi * analyses was used to identify the hotspots and coldspots. SaTScan v10.2 software was applied to detect spatiotemporal clusters. The Spearman correlation analysis was used to examine the relationship between rodent viral load index and HFRS incidence. ARIMA model was constructed and optimized using Bayesian information criterion (BIC) for short-term prediction of HFRS. Results:From January 2013 to December 2024, a total of 1 045 HFRS cases were reported in Jixi City, with an average annual incidence rate of 5.09/100 000. Three epidemic peaks were observed: 2014 (8.12/100 000), 2019 (7.22/100 000), and 2023 (3.86/100 000). The temporal distribution showed a bimodal pattern, with the autumn-winter peak (October to December) having more cases than the spring-summer peak (May to June). Geographically, cases were mainly concentrated in the central-eastern urban areas of Jixi City. The average annual incidence rate in males (7.89/100 000) was significantly higher than that in females (2.24/100 000), the difference was statistically significant ( χ2=322.15, P<0.001). The highest incidence rate was observed in the 50 to 59 age group (6.79/100 000), and farmers accounted for the largest proportion of cases (59.04% (617/1 045)). Spatial analysis revealed clustered distribution (Moran I=0.50, P<0.05), with hotspots in Hulin City and Mishan City. Spatiotemporal analysis identified one significant cluster (radius=89.2 km). No correlation was found between the rodent viral load index and HFRS incidence ( r=0.455, P=0.138). The optimal short-term prediction model was ARIMA (1, 0, 0) (0, 1, 1) (BIC=-3.24), which forecasted 38 HFRS cases in Jixi City in 2025. Conclusions:HFRS incidence in Jixi City exhibits periodicity, seasonality, and spatial clustering. The developed ARIMA model provides a valuable tool for predicting incidence trends, thus to optimize vaccination, rodent control, and surveillance measures in high-risk areas and populations.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Objective:To explore the clinical effect of treating complex talar neck fractures with double-column fixation using plates and cannulated screws.Methods:A retrospective analysis was performed on the data of 13 patients with complex talar neck fractures treated with double-column fixation using plates and cannulated screws at Tianjin Hospital, Tianjin University from June 2019 to November 2023. There were 9 males and 4 females, with an age of 42.1±17.7 years (range, 15-66 years). There were 5 cases on the left and 8 cases on the right. Four cases were caused by traffic accidents, 8 by falling from a height, and 1 by a heavy object injury. According to the Hawkins classification, there were 12 cases of type II and 1 case of type III talar neck fractures. All the fractures were comminuted, including 12 cases of talar neck combined with talar body, and 3 cases combined with subluxation of subtalar joint. The time from injury to surgery was 3.3±1.6 d (range, 1-6 d). All patients were treated with anteromedial combined anterolateral approach, plate and cannulated screw double-column fixation pattern. The healing time of fractures and the occurrence of complications were recorded. Postoperative anteroposterior and lateral X-ray images were taken to assess the quality of fracture reduction based on the presence or absence of step-offs and angulation after reduction of fractures at the neck or body of the talus. The functional outcome was evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale.Results:All 13 patients were followed up for 33.8±15.2 months (range, 12-53 months). All fractures healed, and the healing time was 17.2±2.8 weeks (range, 13-23 weeks). Postoperative X-ray evaluation showed that 10 cases had anatomical reduction and 3 cases had near-anatomical reduction. After operation, there was no loosening or breakage of implant, loss of fracture reduction, irritation of skin and soft tissue by internal fixation. The AOFAS score was 88.1±13.0 points (range, 48-100 points), with 9 excellent cases, 3 good cases, and 1 poor case. Superficial skin necrosis in one surgical incision healed after dressing exchange. At the 1-year follow-up after surgery, 1 case developed avascular necrosis of the talus without collapse. And at the last follow-up (postoperative 13 to 53 months), 5 cases developed post-traumatic arthritis.Conclusion:Plate and cannulated screw double-column fixation in the treatment of complex talar neck fractures can achieve satisfactory reduction and strong fixation effects, which is beneficial in reducing complications related to poor reduction.

Objective:To explore the advantages of individualized 3D-printed vaginal cylinder template-guided interstitial brachytherapy (3D-p-VC-ISBT) in locally advanced cervical cancer, aiming to provide reference for clinical adaptive brachytherapy.Methods:Clinical data of 20 patients with locally advanced cervical cancer admitted to Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine from September, 2021 to August, 2023 were retrospectively analyzed. The median age was 54 years old (32-69 years). Among them, 3 patients were diagnosed with adenocarcinoma and 17 cases of squamous cell carcinoma. According to the treatment method, all patients were divided into intracavitary brachytherapy group (ICBT-plan group, n=10) and 3D-p-VC-ISBT group (3D-p-VC-ISBT treatment-plan group, n=10). A pretreatment plan was designed for each patient undergoing 3D-p-VC-ISBT. The pretreatment plans were formed as the pretreatment-plan group. Dose volume histogram was used to evaluate dose distribution of the targets and organs at risk (OAR). Comparison between two groups was analyzed by Mann-Whitney test and comparison among three treatment plans (ICBT, 3D-p-VC-ISBT treatment-plan and 3D-p-VC-ISBT pretreatment-plan) was analyzed by Kruskal-Wallis test. Results:The mean D 90rel (representing the dose received by 90% volume of the target area divided by the prescription dose) of high-risk clinical target volume (HR-CTV) in 3D-p-VC-ISBT, pretreatment-plan and ICBT-plan groups were 100.47%, 104.66% and 85.91%, respectively. The conformity indexes were 0.66, 0.72 and 0.68, respectively. There was no significant difference in D 0.01 cm3, D 2 cm3 and D 5 cm3 of bladder, rectum and sigmoid colon among the three groups (all P>0.05). For the 3D-p-VC-ISBT treatment-plan group, the D 2 cm3 values of the small intestine at 6 Gy and 7 Gy prescription doses were 169.51 cGy and 111.93 cGy respectively, which were superior to those of the ICBT-plan group (343.07 cGy at 6 Gy prescription, P<0.01). Conclusions:Individualized 3D-p-VC-ISBT is superior to ICBT in terms of dose distribution of HR-CTV, and it can adaptively adjust the insertion plan according to changes in tumor volume and position, making the operation safer and more efficient.

Objective:To compare the antiplatelet effects of vicagrel and clopidogrel in patients with different cytochrome P450 (CYP) 2C19 genotypes.Methods:This is a post-hoc analysis of a phase Ⅱ clinical trial of vicagrel, which included patients with coronary heart disease who underwent percutaneous coronary intervention from August 2018 to June 2019 in 18 centers. Patients were categorized based on the presence of CYP 2C19 *2 or *3 loss-of-function (LOF) alleles into LOF carrier group ( n=111) and non-LOF carrier group ( n=90). Each group included patients received vicagrel 5 mg, 6 mg, 7.5 mg, or clopidogrel 75 mg for 28 days per study protocol. P2Y 12 reaction units (PRU) were measured using VerifyNow at baseline, 6 to 8 hours after loading dose, 7 to 10 days after randomization, and 28 days after randomization and the percentage inhibition of platelet aggregation (%IPA) was calculated. The primary endpoint was %IPA on day 28. Within the patients from the General Hospital of Northern Theater Command, 8 to 12 patients in each study arms were enrolled in a prespecified pharmacokinetic sub-study, measuring the time to reach maximum plasma concentration (T max), peak plasma concentration (C max), and area under the plasma concentration-time curve (AUC). Results:Among 201 patients, the age was (58.8±8.5) years, and 139 (69.2%) were male. In non-LOF carriers, there was no significant differences in PRU values and %IPA between the vicagrel 5 mg, 6 mg, 7 mg, and clopidogrel groups at all time points (all P>0.05). In LOF carriers, %IPA was significantly higher in the vicagrel-treated groups than in the clopidogrel group at 6-8 hours after loading dose (22.9 (14.2, 31.5)% vs. 19.8 (11.0, 28.6)% vs. 29.5 (20.9, 38.0)% vs. 12.9 (3.9, 21.9)%, P=0.038) and 7-10 days after randomization (22.4 (14.2, 30.5)% vs. 34.4 (26.1, 42.6)% vs. 39.8 (31.8, 47.9)% vs. 24.7 (16.3, 33.2)%, P=0.001), with a trend towards higher %IPA in the vicagrel-treated groups at day 28 (30.4 (21.3, 39.6)% vs. 36.5 (27.2, 45.7)% vs. 40.8 (31.8, 49.8)% vs. 30.7(21.2, 40.2)%, P=0.056). Pharmacokinetic results of 35 patients showed that the C max and AUC of the active metabolite M15-2 of vicagrel was similar to that of clopidogrel in non-LOF carriers, but AUC between vicagrel 5 mg, 6 mg, 7 mg and clopidogrel were significantly different in LOF carriers ((5.6±0.6) h·μg -1·L -1 vs. (6.8±2.7) h·μg -1·L -1 vs. (9.2±3.3) h·μg -1·L -1 vs. (4.2±1.9) h·μg -1·ml -1, P=0.020). Conclusion:Vicagrel and clopidogrel have similar antiplatelet effects in non-LOF carriers, but vicagrel exhibits superior antiplatelet effects in LOF carriers.
