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.

Tujia ethnic group medicine Xuetong is derived from Kadsura heteroclita, the stem of which has the medicinal value for anti-rheumatoid arthritis, liver protection, anti-tumor, anti-oxidation effects, and has been widely used in Hunan and Guangdong in China. The selection of reliable and stable reference genes is the basis for subsequent molecular research on K. heteroclita. In this study, GAPDH, TUA, Actin, UBQ, EF-1α, 18S-rRNA, CYP, UBC, TUB, H2A, and RPL were selected as candidate reference genes in Kadsura heteroclita. The gene expression levels of the 11 candidate reference genes of K. heteroclita in its 6 different parts(stem-inside of the cambium, stem-outside of the cambium, fruit, flower, root, and leaf) and under different intervention conditions [drought stress, salt stress, and methyl jasmonate(MeJA) treatment] were detected by quantitative real-time polymerase chain reaction(qRT-PCR). The expression stability of the 11 candidate reference genes was comprehensively analyzed and evaluated by geNorm, NormFinder, ΔCT algorithm, and RefFinder software. The results showed that the expression of UBC and RPL was relatively stable in 6 different parts, and UBC and GAPDH genes were relatively stable under different intervention conditions. To verify the reliability of reference genes for K. heteroclita, this study further examined the relative expression levels of KhFPS, KhIDI, KhCAS, KhSQE, KhSQS, KhSQS-2, KhHMGS, KhHMGR, KhMVD, KhMVK, KhDXR, KhDXS, KhPMVK, and KhGGPS in different parts and under different intervention conditions, which might relate to the synthesis of the main component(Xuetongsu) of K. heteroclita. The results showed that with UBC and RPL or UBC and GAPDH as the reference genes, the expression trends of these 14 genes were basically consistent in different parts or under different intervention conditions for K. heteroclita. In conclusion, UBC can be used as a reference gene of K. heteroclita for its different parts and different intervention conditions, which lays a foundation for further research on the biosynthetic pathway of main components in K. heteroclita.

[Objective]Childhood trauma(CT)is considered one of the major risk factors for developing major depres-sive disorder(MDD)in adulthood.However,the neural basis of MDD patients with CT(CT-MDD)remains poorly under-stood.Therefore,the objective of our study is to explore the resting-state global brain functional connectivity(FC)in CT-MDD.[Methods]A total of 34 CT-MDD and 34 healthy controls performed resting-state fMRI.Whole-brain voxel-level degree centrality(DC)analysis was performed,and the brain regions with significant differences between the two groups were selected as region of interest(ROI)for further estimating the global brain FC.Subsequently,correlation analysis was performed between DC values,FC values in abnormal brain areas and clinical characteristics.[Results]The CT-MDD group showed increased DC value of the right middle frontal gyrus(MFG)compared with the healthy controls.Seed-based FC revealed that the CT-MDD group showed increased connections between the left precuneus and the right MFG or the right medial prefrontal cortex,relative to healthy controls(threshold at P<0.05).Additionally,the DC value of the right MFG was correlated with the severity of CT.[Conclusion]Our results show the increased FC between the left precuneus and the ROI(right MFG)as well as the right medial prefrontal cortex,which are two important brain regions within the de-fault mode network(DMN),and might suggest increased synchronism between the cognitive executive networks and DMN in CT-MDD.These findings may provide insights into the pathophysiological mechanisms underlying CT-MDD.

BACKGROUND:As tissue engineering brings new hope to the worldwide problem of articular cartilage repair,the construction of light-curing 3D printed hydrogel scaffolds with biomimetic composition is of great significance for cartilage tissue engineering. OBJECTIVE:To construct a biomimetic methacryloylated hyaluronic acid/acellular Wharton's jelly composite hydrogel scaffold by digital light processing 3D printing technology,and to evaluate its biocompatibility. METHODS:Wharton's jelly was isolated and extracted from human umbilical cord,then decellulated,freeze-dried,ground into powder,and dissolved in PBS to prepare 50 g/L acellular Wharton's jelly solution.Methylallylated hyaluronic acid was prepared,lyophilized and dissolved in PBS to prepare 50 g/L methylallylated hyaluronic acid solution.Acellular Wharton's jelly solution was mixed with methacrylyacylated hyaluronic acid solution at a volume ratio of 1:1,and was used as bio-ink after adding photoinitiator.Methylacrylylated hyaluronic acid hydrogel scaffolds(labeled as HAMA hydrogel scaffolds)and methylacrylylated hyaluronic acid/acellular Wharton's jelly gel scaffolds(labeled as HAMA/WJ hydrogel scaffolds)were prepared by digital light processing 3D printing technology,and the microstructure,swelling performance,biocompatibility,and cartilage differentiation performance of the scaffolds were characterized. RESULTS AND CONCLUSION:(1)Under scanning electron microscope,the two groups of scaffolds showed a three-dimensional network structure,and the fiber connection of HAMA/WJ hydrogel scaffold was more uniform.Both groups achieved swelling equilibrium within 10 hours,and the equilibrium swelling ratio of HAMA/WJ hydrogel scaffold was lower than that of HAMA hydrogel scaffold(P＜0.05).(2)CCK-8 assay showed that HAMA/WJ hydrogel scaffold could promote the proliferation of bone marrow mesenchymal stem cells compared with HAMA hydrogel scaffold.Dead/live staining showed that bone marrow mesenchymal stem cells grew well on the two groups of scaffolds,and the cells on the HAMA/WJ hydrogel scaffolds were evenly distributed and more cells were found.Phalloidine staining showed better adhesion and spread of bone marrow mesenchymal stem cells in HAMA/WJ hydrogel scaffold than in HAMA.(3)Bone marrow mesenchymal stem cells were inoculated into the two groups for chondrogenic induction culture.The results of qRT-PCR showed that the mRNA expressions of agglutinoglycan,SOX9 and type Ⅱ collagen in the HAMA/WJ hydrogel scaffold group were higher than those in the HAMA hydrogel scaffold group(P＜0.05,P＜0.01).(4)These findings indicate that the digital light processing 3D bioprinting HAMA/WJ hydrogel scaffold can promote the proliferation,adhesion,and chondrogenic differentiation of bone marrow mesenchymal stem cells.

Objective:To analyze the relationship between Twist2 and the prognosis and vascular infiltration of ovarian cancer patients,and to explore the role and mechanism of Twist2 in vascular infiltration of ovarian cancer.Methods:KM plotter was used to explore the correaltion between Twist2 mRNA expression and overall survival(OS),progression free survival(PFS)and post progression survival(PPS)in ovarian cancer.To analyze the cor-relation between Twist2 and vascular infiltration in ovarian cancer using the cancer genomics database cBioPor-tal.In vitro experiment:Transwell method was employed to determine the role of Twist2 in the invasion and migra-tion abilities of ovarian cancer cell CAOV3[blank group,negative control group(siNC group),siTwist2 group].Uti-lizing Realtime-PCR and Western blot to clarify the changes in Twist2 and VEGFC expression in CAOV3 cells af-ter downregulating Twist2 expression at the RNA and protein levels,respectively.Results:①Online data analysis of KM plotter showed that the ovarian cancer patients with high expression of Twist2 were associated with poor prognosis,with OS(HR 1.24,95％Cl 1.01-1.52),PFS(HR 1.39,95％CI 1.14-1.70)and PPS(HR 1.37,95％CI 1.08-1.74)all showing statistical significance(P＜0.05).CBioportal analysis showed that Twist2 mRNA expression was positively correlated with vascular infiltration(r=0.93,P=0.001)and lymphatic infiltration(r=0.89,P=0.009)in ovarian cancer.②Compared with the blank group and siNC group,in vitro experiment Tran-swell assay showed that the invasion and migration ability of ovarian cancer cells in siTwist2 group was significant-ly reduced(P＜0.05).In mRNA and protein level,Realtime-PCR and Western blot showed that compared with the blank group and siNC group,the expression of Twist2,as well as VEGFC,were significantly reduced in the siTwist2 group(P＜0.05).Conclusions:The expression of Twist2 in ovarian cancer is closely related to tumor prognosis and vascular infiltration.After downregulating Twist2,the number of cells that migrate and invade is sig-nificantly reduced,and the expression of VEGFC is reduced.Twist2 can induce migration and invasion of ovarian cancer cells through VEGFC,which may be one of the indicators for prognosis evaluate and targeted therapy of ovarian cancer in future.
