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.

Background A large number of power supply workers are involved in live working and are exposed to multiple risk factors for long periods of time during outdoor work, which in turn causes occupational health problems. Objective To identify potential ergonomic factors related to work-related musculoskeletal disorders (WMSDs) and estimate the ergonomic risk of electricians. Methods A total of 31 workers were randomly selected from a training base under a power supply enterprise in Guangxi, and their operation processes were recorded by video. Using the Rapid Upper Limb Assessment (RULA) method, the workers were scored by the posture of their arms, neck, and torso during operation, and the final scores were summarized to assess their risk level. Two independent samples t-tests were used to compare the differences in RULA scores. Results A total of 31 videos for mounting/dismounting insulation mask and 29 videos for breaking/connecting contact terminal were collected. The RULA score for mounting/dismounting insulation mask was 6.6 ± 0.7 (left side) and 7.0 ± 0.2 (right side), most of the workers had a score of 7 (71.0% on the left side and 96.8% on the right side), and the upper limb and overall scores on the right side were higher than those on the left side (P < 0.05). The RULA score for breaking/connecting contact terminal was 6.9 ± 0.4 (both right and left sides), most of workers had a score of 7 (89.7% on the left side and 93.1% on the right side), and the difference of the overall scores between the right and left side for this operation were not statistically significant (P > 0.05). The ergonomic risk levels for both operations were level 3 or higher. Conclusion Mounting/dismounting insulation mask and breaking/connecting contact terminal are typical upper limb operations, and have a high level of ergonomics risk, requiring effective preventive and protective measures.

Mass vaccination represents a highly effective strategy for accelerating disease control while simultaneously reducing incidence and mortality rates. By developing comprehensive plans and standards for mass vaccination, it is feasible to optimize resource allocation and swiftly enhance vaccination coverage, thereby preventing, controlling, or interrupting outbreaks or epidemics of specific infectious diseases. To standardize the mass vaccination process and establish a population immunity barrier in an orderly, efficient, and safe manner, a panel of experts was convened to develop the Recommendations on Mass Vaccination. These recommendations are grounded in the requirements of relevant policies and regulations in China, as well as the insights gained from the mass vaccination campaign for COVID-19 vaccines conducted in the country. The recommendations outline the system requirements pertaining to initiation conditions, departmental coordination, responsibilities, mobilization, operational specifications, and responses to vaccine reactions, among other aspects of mass vaccination implementation, so as to serve as a reference for future mass vaccination initiatives and the formulation of related policies.

Objective To select excellent tomato mutants by space treatment and to cultivate directively new varieties for production application.Method Growth dynamics and change of agricultural characters of the mutant of indeterminate growth habit was observed.And the enzymogram and activity of two kinds of main isoenzyme were analyzed.Result An indeterminate growth habit mutant(M1) which derived from a determinate growth habit cultivar(10-3-2) was obtained from the 1st generation after space treatment(SP_1).Being an inherited character,the indeterminate growth habit of the mutant can be expressed from generation to generation.The plant height of M1 was 145 cm,42.0 cm higher than that of the background one(increased by 29.6%),when the background plant height was determined.The main stem diameter of the mutant was 1.22 cm,0.34 cm thicker than that of background parent.However,there were no visible difference in the fruit size and fruit set percentage between them.The biological characters of M1 and its progenies were studied,and the results showed that the indeterminate growth have no side effects on the agronomic characters and fruit quality,and the mutant had a potentiality of higher yield if the condition is suitable.The activity of two enzymes,SOD and POD,was assayed and there were no obvious difference of SOD activities and enzymograms between the mutant and its background parent,but POD activity was much lower in mutant than that in its background parent.Conclusion After observation through 3 generations,it is found that indetermination growth habit is inheritable and stable.

Objective To evaluate the indeterminate growth mutant of tomato derived by space mutagenesis to provide the basis for selecting and cultivating the molecular markers of tomato growth habit. Methods Fifty 10-mer randomly amplified polymorphic DNA(RAPD) primers were used to examine the polymorphism of M1 and 10-3-2. Their polymorphic fragments were cloned, and then were transferred to SCAR markers. Results Of all the 50 10-mer RAPD primers, 44 primers amplified polymerase chain reaction(PCR) products and 2 primers (S165 and S168) amplified stable reproducible polymorphic products. The molecular weight of the specific amplified products were 300 bp and 1 500 bp respectively, therefore they were named as TRS165300 and TRS1681500 temporarily. And TRS1681500 was transferred into stable sequence characterized amplified region(SCAR) marker and this marker could be a specific genetic marker of this indeterminate growth habit mutant. Conclusion Space mutation can produce mutants at DNA level from the loaded materials. The indeterminate growth mutant of tomato is derived by space mutagenesis which can provide a valuable material for studying the regulation and control of tomato growth habit.
