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.

In 2022,breast cancer ranks the first in incidence among all malignant tumors worldwide,and it's high recurrence and fatality rate has posed serious threat to human life and health.Triple negative breast cancer(TNBC)is known for its poor prognosis among all types of breast cancer,and is often associated with elevated expression of epidermal growth factor receptor(EGFR).EGFR is widely expressed on the surface of various cells.The signaling pathway mediated by EGFR is mainly involved in cell growth,proliferation and differentiation.EGFR overexpression is often closely related to tumor invasion,metastasis and prognosis.Therefore,elucidating the roles of EGFR in TNBC and developing prevention and treatment strategies correspondingly are helpful to prevent and control the occurrence of breast cancer,and improve patients'quality of life.This review summarizes the research progress in the roles of EGFR,the treatment strategies and drug resistance in TNBC,in order to provide more refence for treating and improving the prognosis of breast cancer.

Objective To investigate the effect of different optimization algorithms on accurate reconstruction of traffic accidents. Methods Non-dominated sorting genetic algorithm-II ( NSGA-II), neighborhood cultivation genetic algorithm (NCGA) and multi-objective particle swarm optimization (MOPSO) were used to optimize the multi-rigid body dynamic reconstruction of a real case. The effects of different optimization algorithms on convergence speed and optimal approximate solution were studied. The optimal initial impact parameters were simulated as boundary conditions of finite element method, and the simulated results were compared with the actual injuries. Results NCGA had a faster convergence speed and a better result in optimization process. The kinematic response of pedestrian vehicle collision reconstructed by the optimal approximate solution was consistent with the surveillance video. The prediction of craniocerebral injury was basically consistent with the cadaver examination. Conclusions The combination of optimization algorithm, rigid multibody and finite element method can complete the accurate reconstruction of traffic accidents and reduce the influence of human factors.

Objective:To analyze the clinical characteristics, diagnosis and treatments of patients with POEMS syndrome initially diagnosed as pulmonary hypertension (PH).Methods:Clinical data of 7 patients who were initially diagnosed as PH and finally diagnosed as POEMS syndrome in Shanghai Pulmonary Hospital from May 2013 to November 2021 were retrospectively reviewed. Clinical manifestations, laboratory tests, echocardiography, hemodynamic findings, treatment and prognosis of patients were analyzed.Results:Seven patients, including 4 males and 3 female, aged (55±9) (44-62) years were presented with elevated pulmonary artery pressure by echocardiography at admission. Chest tightness and shortness of breath (7/7), fatigue (6/7) and lower limb edema (4/7) were the most common symptoms in the first-episode. Meanwhile, patients also presented symptoms associated with POEMS syndrome, including multiple peripheral neuropathy (7/7), multiserosal cavity effusion (6/7), organomegaly (5/7), skin changes (5/7), and endocrine lesions (4/7). Serum levels of vascular endothelial growth factor (VEGF) were significantly increased in all patients. The pulmonary arterial systolic blood pressure was (66±21)mmHg (1 mmHg=0.133 kPa) estimated by echocardiography. Six patients underwent right heart catheterization and significantly increased mean pulmonary artery pressure((35±9) mmHg) was confirmed; and their pulmonary vascular resistance was (4.00±2.10) Wood U. All patients received corresponding treatment for POEMS syndrome. The excise tolerance was improved in 5 patients after successful treatment with stable or reversed WHO functional class. One patient received hemodialysis treatment for uncontrolled POEMS. One patient died during follow-up. The echocardiography was followed up in 4 patients, and 2 of whom had a complete reversal of PH, 1 had a partial reversal, and 1 had not yet reversed.Conclusions:In patients with PH who have multisystem manifestations, such as multiple peripheral neuropathy, multiserosal cavity effusion, organomegaly and skin changes, POEMS syndrome should be considered, and proper and active treatment of POEMS may reverse PH and improve the prognosis of patients.

Objective:To investigate the role of signal lymphocyte activating molecule family member 5 (SLAMF5) in liver transplantation rejection in SD rats.Methods:Forty-five male SD rats without special pathogens, weight 260-300 g, aged 10-12 weeks were included. Among them, forty male SD rats (20 donors and 20 recipients respectively) were established with reference to the " two cuff" method. 15 liver transplantation model rats were randomly divided into 1 week (LT-1W) group, 2 weeks (LT-2W) group and 3 weeks (LT-3W) group, with 5 rats in each group, and 5 normal rats were taken as the normal control group. The expressions of SLAMF5, CD4 and CD8 were detected by polymerase chain reaction (PCR), Western blot and immunohistochemistry. The correlations between SLAMF5 expression in the lymphocyte infiltration area and the rejection activity index was analyzed.Results:The levels of alanine aminotransferase, aspartate aminotransferase and total bilirubin were significantly higher in LT-1W group, LT-2W group and LT-3W group than those in the normal control group (all P<0.05). PCR results showed that the relative expression of SLAMF5 mRNA were (5.44±1.11), (4.69±1.12), (2.18±0.68) respectively, which were increased in LT-1W group, LT-2W group and LT-3W group than those in normal control group (1.01±0.23), and the differences were statistically significant (all P<0.05). Immunohistochemical staining showed that SLAMF5 and CD4, CD8 positive T cells were mainly distributed in the portal area, hepatic lobule area and around the proliferative bile duct, and there was a certain overlap. Correlation analysis showed that there was a positive correlation between the expression of SLAMF5 in the lymphocyte infiltration area and the rejection activity index ( r=0.519, P=0.048). Conclusion:The expression of SLAMF5 is increased after liver transplantation in SD rats, and there is a correlation between SLAMF5 expression and liver transplantation rejection in rats.
