Objective To investigate the status of the establishment and service of the rehabilitation departments in comprehensive hospitals in China mainland.Methods A questionnaire survey was conducted in 240 comprehensive hospitals with different grades distributed in the capital city of 31 provinces, autonomous regions, and municipality cities in China mainland in a stratified sampling way. The contents investigated are the settings of rehabilitation departments, the performances of the rehabilitation services, the staffing of the rehabilitation workers and the problems faced in rehabilitation. Then, statistical analysis were done between the developed eastern regions and economically less developed middle-western regions, as well as different grades of comprehensive hospitals. Results In total, 216 valid questionnaires were collected (72 tertiary hospitals, 72 secondary hospitals and 72 primary hospitals), and there are no statistically difference between eastern regions and middle-western regions(P=0.61). About 69% of the hospitals surveyed have built up the rehabilitation departments, and there are no statistically difference between different regions (P=0.30). As far as the performance of the rehabilitation services are concerned, 97.2% of them have carried out rehabilitation service, 60% of them can satisfy the demands of the patients, and there are no difference between the different grades and between the eastern and middle-western regions(P>0.05). In addition, 76.4% of them have rehabilitation doctors, 68.4% have physiotherapists(PT), 52.3% have traditional Chinese medicine doctors, 50.5% have occupational therapists(OT), 36.9% have speech therapists(ST), 17.8% have psychologists, and only 2.3% have social workers. The staff status on PT, OT and ST of the hospitals in eastern regions are significantly better than that in middle-western regions(P<0.01), and the staff status on rehabilitation doctors, PT, OT, ST and psychologists in the tertiary hospitals are significantly better than that in the secondary hospitals and primary hospitals(P<0.01). Finally, the first five problems the rehabilitation department faced are following: short of professional workers(63.9%), lack of training areas(51%), lack of modern rehabilitation service management system (50.5%), out-of-date equipments(49.5%) and low fees of rehabilitation treatment(49.1%). Conclusion Many problems exists in the rehabilitation departments of comprehensive hospitals, such as the development of rehabilitation departments, the professional workers, the quality and width of the service, the efficient use of rehabilitation resources, rehabilitation management and profession permission, the relative policies and regulations, personnel training and so on. Therefore, the government should enhance to put the supported policies into practice, and reinforce investment to the comprehensive hospitals, in particular, enhance the support of the comprehensive hospitals in middle-western regions, as well as the primary hospitals and the secondary hospitals, all of which will play a much more efficient role in rehabilitation for the disabled in the comprehensive hospitals.

Objective To investigate the imaging features of primary Rosa-i Dorfman disease (RDD)in the central nervous system and to increase the understanding of the disease.Methods The MRI findings of 5 cases with primary RDD of the central nervous system were analyzed retrospectively,and the related literatures were reviewed.Results Four cases located in the cranium,1 case located in the spinal cord,and 5 tumors were attached to the brain (ridge)membrane.The tumor was equal and low signal on T1 WI,and equal or slightly high signal on T2 WI.Obvious enhancement could be seen on enhance study,and obvious enhancementwas visible in adjacent brain (ridge)membrane,in which 1 case involved the skull,with thickening and strengthening of the skull.Tumors were attached to the meninges in a wide range,the local meninges of 3 cases were penetrated by tumor.Conclusion If young and middle-aged males have no obvious specific clinical manifestations,the images of MRI are single or multiple lesions that are closely related to the brain (ridge)membrane in larger extent and easily penetrate the brain (ridge)membrane,the possibility of RDD should be considered.

Objective:To investigate whether coxsackievirus A 16 (CVA16) infection would affect the expression of N6-methyladenosine (m 6A) methylation-related proteins in human bronchial epithelial cells (16HBE), ICR suckling mice and SCRBA2 humanized mice and influence their subcellular localization. Methods:CVA16 was used to infect 16HBE cells at a multiplicity of infection (MOI) of 0.1 and mice at 10 7 CCID 50/ml. Changes in the expression of methyltransferases, demethylases and methylated reading proteins were analyzed by Western blot. Cellular localization of these proteins was observed using immunofluorescence. Results:The expression of m 6A methylation-related proteins was gradually reduced in CVA16-infected cells with time, but showed no obvious change in ICR suckling mice or SCRBA2 humanized mice. After infection, m 6A methylation-related proteins were redistributed in both the nucleus and cytoplasm and even degraded. Conclusions:CVA16 replication in host cells altered the expression and cellular localization of m 6A methylation-related proteins, which indicated that m 6A modification might be a new potential target for enterovirus therapy.

We aimed to express and purify three rabies virus glycoproteins with different tags and sizes. After analyzing their binding function, we wish to obtain a rabies virus glycoprotein with higher affinity and ability to specifically bind memory B cells. Experiments were carried out to express full length, as well as the ectodomain RVG by gene engineering method. Combined with the antibody of CD19 and CD27, the candidate protein labeling with fluorescence was used to analyze its binding function. Flow cytometry was used to detect the anti-rabies virus specific memory B cells in PBMCs, and confirm the binding ability between the candidate proteins and anti-rabies virus-specific memory B cells. We successfully constructed three expression vectors pGEX-5X-1-RVG, pET28a-RVG and pET30a-G. Three glycoproteins GST-RVG, His-RVG and His-G were obtained by optimized expression and purification conditions. The antigen specificity of purified GST-RVG, His-RVG and His-G were identified by Western blotting and ELISA. The affinity of these three purified glycoproteins to anti-rabies virus antibody were detected by competitive ELISA. Anti-rabies virus specific memory B cells in positive PBMCs gained from people who had ever been injected with the vaccine can be detected by flow cytometry. Thus, we got a recombinant rabies virus glycoprotein that had high-affinity and could sort antigen specific memory B cells.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.
