ABSTRACT

Objectives:To investigate the current research status and focus of multi-campus construction and management in public hospitals, and to provide research reference and policy recommendations.Methods:The CNKI and Wanfang databases were searched from the establishment of the databases to October 31, 2020. Literatures of multi-campus construction and management in public hospitals were screened following inclusion and exclusion criteria. Bibliometric analysis was used to analyze the characteristics of the included literatures.Results:A total of 99 articles were included. In 2019, there were 18 articles, which was the most over the years. The number of published literatures has increased significantly since 2014. The most common origin cities of publications were Shanghai, Wuhan and Beijing. Literature research focused on integration, homogeneity, economic operation, cultural construction and development strategy.Conclusions:The development of multi-campus in public hospitals has attracted more and more attention, but it has not yet involved in the research of setting access, functional positioning, construction mode, peacetime and wartime transformation, and it is predicted that it will become a research hotspot in the future.

ABSTRACT

Under the diagnosis-related groups(DRG) prospective payment system, innovative health technologies with high costs and risks may be limited to some extent. How to balance the increase of health care cost and the development of innovative health technology is a difficult problem to be solved in the current reform. By studying the relatively mature payment systems of innovative health technologies in the world, the authors found that countries generally adopted additional payment or compensation to encourage the development of new technologies. But at the same time, a relatively perfect health technology assessment and payment management mechanism had been established to ensure the standardized operation of payment plan. These international advanced experience and practice could provide references for China′s innovative health technology payment strategy under the DRG payment system. It is suggested to establish a scientific and reasonable assessment mechanism of innovative health technology, create a special access channel for innovative health technology with limited short-term evidence, and gradually form a long-term incentive mechanism of innovative health technology in DRG payment system.

ABSTRACT

Objective:To investigate multimodality imaging characteristics and clinical features of lymphomatosis cerebri (LC) and reasons for misdiagnosis,with the goal of potentially facilitating an early and accurate diagnosis for this often-missed disease.Methods:Clinical data and cerebral multimodality imaging findings from 11 patients with LC proven basing on pathology in the Affiliated Hospital of Guizhou Medical University from November 30, 2011 to December 28, 2020 were retrospectively extracted, analyzed, and reviewed in combination with the literatures.Results:The common presenting symptoms with subacute onset included cognitive decline (8/11), gait disturbance (9/11), and behavioral disturbance (5/11). Test of cerebrospinal fluid showed that the number of cells and the level of protein increased (8/10), the sugar content (2/10) and chloride (4/10) decreased. The imaging manifestations of 11 patients with LC were diffuse lesions of bilateral cerebral white matter in the both deep and lobar lesion distribution, involving the cerebral cortex and subcortical white matter in eight cases (8/11), basal ganglia in seven cases (7/11), thalamus in five cases (5/11), cerebellum in six cases and brain stem in six cases (6/11). All 11 patients showed equal or slightly low-density shadows on CT plain scan and slightly longer T 1WI and T 2WI signals on magnetic resonance imaging. Six cases (6/11) had no obvious enhancement in the early stage, and five cases and six follow-up cases showed heterogenous spots, patches, nodules or clusters of distinct enhancement. Diffusion-weighted imaging showed non restricted diffusion in nine (9/11) cases initially diagnosed, and restricted diffusion in two cases (2/11) and nine follow-up cases, which were hyperintense on diffusion-weighted imaging and hypointense on apparent diffusion coefficient maps. Five patients (5/5) presented a marked decrease in N-acetyl aspartic acid (NAA)/creatine (Cr) and increase in choline (Cho)/Cr on hydrogen proton magnetic resonance spectrum, including an increase in lipid/Cr in three cases. One case (1/3) showed no abnormal increase in lesion metabolism, and two cases (2/3) showed slightly increased uptake on positron emission tomography/CT. Conclusions:Diffuse bilateral cerebral lesions especially in deep and lobar region, without enhancement or with patchy enhancement, marked decrease in NAA/Cr and increase in Cho/Cr and Lip/Cr are suggestive of LC. Misdiagnosis may be mainly due to insufficient understanding and improper brain biopsy.

ABSTRACT

Objective:To evaluate the efficacy and long-term effect of functional electrical stimulation (FES) on cerebral palsy. Methods:Literature retrieval was carried out in the electronic databases of PubMed, Embase, Web of Science, Cochrane Library, China Biology Medicine Disc (CBM), CNKI, Wanfang Database and VIP. The time limit was from the establishment of these databases to March 26th, 2020. According to the inclusion and exclusion criteria, randomized controlled trials about FES for children with cerebral palsy were included. At least two evaluators extracted the data independently and used Cochrane 5.1.0 bias risk assessment tool to evaluate the quality of included studies. The data was analyzed with Review Manager 5.3 software. Results:A total of eleven studies with 513 children were included. The Gross Motor Function Measure-88 (GMFM-88) D/E scores (MD = 8.14, 95%CI 6.26 to 10.02, P < 0.001), GMFM-88 B score (MD = 8.77, 95%CI 4.00 to 13.53, P < 0.001), modified Ashworth Scale (MAS) score (MD = -1.05, 95%CI -1.25 to -0.84, P < 0.001), Kyphosis angle (MD = -10.67, 95%CI -12.21 to -9.13, P < 0.001), Cobb's angle (MD = -2.66, 95%CI -3.38 to -1.93, P < 0.001), step length (MD = 3.35, 95%CI 1.81 to 4.90, P < 0.001), walking speed (MD = 0.09, 95%CI 0.05 to 0.14, P < 0.001) and GMFM score at six weeks follow-up (MD = 4.84, 95%CI 1.90 to 7.77, P = 0.001) were better in FES group than in the control group. There was no significant difference in MAS score between two groups after six weeks of follow-up (MD = 0.04, 95%CI -0.30 to 0.37, P = 0.84). Conclusion:FES could improve the lower-limb and trunk function of children with cerebral palsy, however, the long-term effect of relieving muscle spasm was not significant.

ABSTRACT

Objective@#The coronavirus disease 2019 (COVID-19) pandemic continues to present a major challenge to public health. Vaccine development requires an understanding of the kinetics of neutralizing antibody (NAb) responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).@*Methods@#In total, 605 serum samples from 125 COVID-19 patients (from January 1 to March 14, 2020) varying in age, sex, severity of symptoms, and presence of underlying diseases were collected, and antibody titers were measured using a micro-neutralization assay with wild-type SARS-CoV-2.@*Results@#NAbs were detectable approximately 10 days post-onset (dpo) of symptoms and peaked at approximately 20 dpo. The NAb levels were slightly higher in young males and severe cases, while no significant difference was observed for the other classifications. In follow-up cases, the NAb titer had increased or stabilized in 18 cases, whereas it had decreased in 26 cases, and in one case NAbs were undetectable at the end of our observation. Although a decreasing trend in NAb titer was observed in many cases, the NAb level was generally still protective.@*Conclusion@#We demonstrated that NAb levels vary among all categories of COVID-19 patients. Long-term studies are needed to determine the longevity and protective efficiency of NAbs induced by SARS-CoV-2.

ABSTRACT

BACKGROUND@#Innovative coronavirus disease 2019 (COVID-19) vaccines, with elevated global manufacturing capacity, enhanced safety and efficacy, simplified dosing regimens, and distribution that is less cold chain-dependent, are still global imperatives for tackling the ongoing pandemic. A previous phase I trial indicated that the recombinant COVID-19 vaccine (V-01), which contains a fusion protein (IFN-PADRE-RBD-Fc dimer) as its antigen, is safe and well tolerated, capable of inducing rapid and robust immune responses, and warranted further testing in additional clinical trials. Herein, we aimed to assess the immunogenicity and safety of V-01, providing rationales of appropriate dose regimen for further efficacy study.@*METHODS@#A randomized, double-blind, placebo-controlled phase II clinical trial was initiated at the Gaozhou Municipal Centre for Disease Control and Prevention (Guangdong, China) in March 2021. Both younger (n = 440; 18-59 years of age) and older (n = 440; ≥60 years of age) adult participants in this trial were sequentially recruited into two distinct groups: two-dose regimen group in which participants were randomized either to follow a 10 or 25 μg of V-01 or placebo given intramuscularly 21 days apart (allocation ratio, 3:3:1, n = 120, 120, 40 for each regimen, respectively), or one-dose regimen groups in which participants were randomized either to receive a single injection of 50 μg of V-01 or placebo (allocation ratio, 3:1, n = 120, 40, respectively). The primary immunogenicity endpoints were the geometric mean titers of neutralizing antibodies against live severe acute respiratory syndrome coronavirus 2, and specific binding antibodies to the receptor binding domain (RBD). The primary safety endpoint evaluation was the frequencies and percentages of overall adverse events (AEs) within 30 days after full immunization.@*RESULTS@#V-01 provoked substantial immune responses in the two-dose group, achieving encouragingly high titers of neutralizing antibody and anti-RBD immunoglobulin, which peaked at day 35 (161.9 [95% confidence interval [CI]: 133.3-196.7] and 149.3 [95%CI: 123.9-179.9] in 10 and 25 μg V-01 group of younger adults, respectively; 111.6 [95%CI: 89.6-139.1] and 111.1 [95%CI: 89.2-138.4] in 10 and 25 μg V-01 group of older adults, respectively), and remained high at day 49 after a day-21 second dose; these levels significantly exceed those in convalescent serum from symptomatic COVID-19 patients (53.6, 95%CI: 31.3-91.7). Our preliminary data show that V-01 is safe and well tolerated, with reactogenicity predominantly being absent or mild in severity and only one vaccine-related grade 3 or worse AE being observed within 30 days. The older adult participants demonstrated a more favorable safety profile compared with those in the younger adult group: with AEs percentages of 19.2%, 25.8%, 17.5% in older adults vs. 34.2%, 23.3%, 26.7% in younger adults at the 10, 25 μg V-01 two-dose group, and 50 μg V-01 one-dose group, respectively.@*CONCLUSIONS@#The vaccine candidate V-01 appears to be safe and immunogenic. The preliminary findings support the advancement of the two-dose, 10 μg V-01 regimen to a phase III trial for a large-scale population-based evaluation of safety and efficacy.@*TRIAL REGISTRATION@#http://www.chictr.org.cn/index.aspx (No. ChiCTR2100045107, http://www.chictr.org.cn/showproj.aspx?proj=124702).

ABSTRACT

Objective:To design a multimodality wheelchair in order to meet many use requirements of the lower limbs dyskinesia patients. Methods:For some shortcomings of the existing multimodality wheelchair such as heavy structure and drive redundancy, the design of multimodality wheelchair based on double parallelogram mechanism is studied, and a simple and reliable multimodality wheelchair mechanism is presented. Rotary actuation drives the double parallelogram mechanism and makes parts of the wheelchair move, and three posture transformations are realized. The coupling movement of the back and leg rest realizes the transformation of sitting and supine posture, and the coupling movement of seat and back realizes the change of sitting and standing posture. The mechanical analysis of wheelchairs based on uniform load was carried out, and the rotation moment is calculated. Results:When the driving torque changed from sitting position to supine position, it increased with the increase of rotation angle and reached a peak value. When the driving torque changed from sitting position to standing position, it gradually decreased with the increase of rotation angle. Then the dynamics simulation is carried out in Adams software, the calculated results were basically consistent with the simulation results. Conclusion:The proposed mechanism is helpful to realize the lightweight design of multimodality wheelchair, and meets the design needs of intelligent multimodality wheelchair.

ABSTRACT

Abstract  Chimetic antigen receptor T cells (CAR-T) are a kind of novel killer cells derived from autogenous or allogeneic T cells targeting the tumor specific antigens by gene engineering transpormation. The CAR-T cells possess the advantages of high specificity, high efficiency and non-MHC restriction, thus achieving good therapeutic effects in relapsed/refractory hematological tumors and some solid tumors. The process of CAR-T cell preparation includes cell isolation and purification, activation and differentiation, gene modification, in vitro amplification, phenotypic quality control, preservation and reinfusion. In recent years, with the rapid development of flow cytometry, this technology has been widely used in all aspects of CAR-T cell therapy, including pre-treatment screening, in vitro preparation and post-transfusion monitoring, which plays an important role in its innovative optimization.
