OBJECTIVETo determine whether Betahistine mesilate is effective in treating tinnitus.

METHODSRandomized, prospective, double-blind, controlled trial was used in our study. The study group consisted of 60 adult patients who consulted our outpatient clinic complaining of subjective tinnitus, excluded objective tinnitus and the patients who had tinnitus caused by obvious diseases, such as outer and middle ear diseases. Thirty patients were given Betahistine mesilate and Flunarizine Hydrochloride as an experimental group, 30 patients were given Vitamin B6 and Flunarizine Hydrochloride as a control group. After a week of treatment the efficacy of the medicines in two groups was observed. Tinnitus questionnaire was performed before the treatment, and pure tone audiogram, tinnitus pitch and loudness matching were performed both in the beginning and at the end of the treatment.

RESULTSCompletion of treatment, tinnitus loudness matching assessment showed that the efficacy of the Betahistine mesilate group was better then the control group. The efficacy of treatment was respectively 65.5% by per protocol (PP) and 63.3% by intend to treat (ITT) in the Betahistine mesilate group and 39.3% by PP and 36.7% by ITT in the control group. The difference of tinnitus loudness improvement rate between the experimental group and control group was statistically significant. But the subjective tinnitus improvement rate showed no difference between two groups. There were not serious side effects in the two groups.

CONCLUSIONSBetahistine mesilate can be a choice for tinnitus treatment clinically. Further studies of larger series and placebo-controlled trial are needed.

OBJECTIVETo investigate the clinicopathological features of pulmonary lymphangioleiomyomatosis (PLAM).

METHODSBy means of HE and immunohistochemistry (SP method) studies, the clinical and pathological features of 5 PLAM cases were analyzed and the related literature reviewed.

RESULTSPLAM was a rare lung disease of unknown etiology and was restricted to females who were generally pre-menopausal. Pathological features showed abnormal smooth muscle cells (LAM cells) line the airways, lymphatics and blood vesssels leading to airflow obstruction and replacement of the lung parenchyma by cysts. LAM cells were positive for HMB45. Clinically the disease was categorized by dyspnoea, haemoptysis, recurrent pneumothoraces and chylous effusions.

CONCLUSIONSPLAM should be considered when recurrent pneumothorax, haemoptysis and dyspnoea occur in females. Pathologic examination of lung tissue biopsy is required for confirmation of PLAM diagnosis.

OBJECTIVETo identify and characterize the epitope associated with the virus attachment protein (VAP) of hantaan virus.

METHODSThe monoclonal antibody 3G1 was used as the ligand to biospan from a phage-displayed 12-amino acid peptide library, then the positive phage clones were chosen and sequenced. The amino acid sequences of them were compared with that of hantaan virus G2 in homology. The characteristics of positive phage were studied by IFA and ELISA. A decapeptide combining to cell membrane was observed under laser scanning confocal microscope (LSCM).

RESULTSThe conservative motif PX(1-2) HX(0-2) H displaying on positive clones shared homologous amino acid sequence with G2 96YPWHTAKCHY105.

CONCLUSIONG2 96YPWHTAKCHY105 might play some roles in virus binding to host cell, and might be a possible key epitope of hantaan virus VAP.

OBJECTIVETo investigate the changes of CD4(+)CD28(-) T cell and CD4(+)CD25(+) regulatory T cell (Treg) subsets in patients with coronary artery disease (CAD).

METHODSTwenty-eight patients with angiographically established CAD were recruited in this study, including 16 with unstable angina (UA group) and 12 with stable angina (SA group). Eleven patients with chest pain syndrome served as the control group. The proportions of peripheral CD4(+)CD28(-) T cells and CD4(+)CD25(+) Treg subsets were determined with fluorescence-activated cell sorting (FACS).

RESULTSThe proportions of CD4(+)CD25(+) Treg were significantly lower in UA group (6.55-/+2.45%) than in SA (14.01-/+4.92%) and control groups (13.55-/+3.87%). The proportions of CD4(+)CD28(-) T cells were significantly higher in UA group (10.55-/+4.76%) than in SA (2.64-/+1.33%) and control (2.75-/+1.55%) groups.

CONCLUSIONAlterations of circulating T-lymphocyte subsets occur in patients with UA. The changes of Treg and CD4(+)CD28(-) T cells may lead to breakdown of peripheral autoimmune tolerance and play an important role in the development and progression of CHD.

OBJECTIVETo evaluate the efficacy and safety of IDA (Haizheng Parmacy, China) in the treatment of acute leukemia.

METHODSA multi-institutional single-blind randomized controlled clinical trial was carried out. A total of 155 newly diagnosed patients with AML and ALL were enrolled. The patients were randomly divided into two groups, one was given IDA (n = 77) and the other given zevodas (Pharnacia & Upjohn, n = 78) for comparison.

RESULTSAll the patients enrolled in this trial were eligible for assessment of side effects, and 129 patients for evaluation of overall response rate. In patients treated with IDA vs zevodas, the overall response rate (OR) was 78.1% vs 76.9%, CR was 68.8% vs 67.7%; in AML patients, OR was 82.4% vs 71.8%, and CR was 76.5% vs 64.1%; in ALL patients, OR was 80.0% vs 81.8%, and CR was 68.0% vs 68.2%. There was no sitatistically significant difference in hematologic and non-hematologic toxicities between the two groups.

CONCLUSIONThe efficacy of IDA in the treatment of acute leukemia is comparable to that of zevodas. Both have similar toxic side effects.

Objective:To investigate the care needs and influencing factors for caregivers of children with disabilities. Methods:From December, 2019 to January, 2020, and August to September, 2020, a total of 496 family caregivers of children with disabilities were surveyed in Shanghai. The Care Needs Assessment Tool for Children with Disabilities was used to measure the care needs rates and satisfaction, and multiple linear regression was performed to analyze the related factors. Results:The rate of total need was 71.8%, which was high in the information support (83.7%), spiritual support (75.9%) and financial support (74.1%), and was at an intermediate level in alternative service support (62.9%) and professional support (62.2%). The satisfaction of total need was 39.4%, which was at a intermediate level in the spiritual support (50.8%) and professional support (45.5%), and was at a low level in alternative service support (32.8%), financial support (32.3%) and information support (30.3%). The caregivers needed less support for thoses with higher public policy satisfaction (B = -3.252, 95%CI -5.370 to -1.134, P = 0.003) and the children with vision and speech disability, and undetermined disability (B_{vision disability}= -12.160, 95%CI -21.976 to -2.344, P = 0.015; B_{speech disability}= -12.754, 95%CI -22.583 to -2.925, P = 0.011; B_{undetermined disability}= -16.553, 95%CI -24.714 to -8.392, P < 0.001), while mothers (B = 9.071, 95%CI 4.293 to 13.848, P < 0.001) needed more support than grandparents. The caregivers with higher public policy satisfaction (B = 7.392, 95%CI 5.523 to 9.262, P < 0.001), the children with vision disability, hearing disability and speech disability (B_{vision disability}= 8.612, 95%CI 0.081 to 17.144, P = 0.048; B_{hearing disability}= 8.686, 95%CI 1.920 to 15.451, P=0.012; B_{speech disability}= 9.515, 95%CI 1.184 to 17.846, P = 0.025), lower barriers to social inclusion (B = 1.932, 95%CI 0.457 to 3.408, P = 0.010) and shorter average daily care hours (B = -4.123, 95%CI -6.247 to -1.999, P < 0.001) were more satisfactory for support. Conclusion:The care needs of children with disabilities are diverse, with the highest rate of need for information support and the lowest level of satisfaction. There is some variation in the care needs of children with different types of disabilities, family roles, average daily care hours and social environment characteristics.

Objective:To explore the quality of life of caregivers of children with disabilities and its influencing factors. Methods:From December, 2019 to January, 2020, and August to September, 2020, a total of 496 family caregivers of children with disabilities were surveyed in Shanghai. The 12-item Short-form Health Survey (SF-12) was used to measure the quality of life of 496 caregivers, and multiple linear regression was performed to analyze the related factors. Results:The score of physical component summary (PCS) of caregivers was (51.67±8.11), and the score of mental component summary (MCS) was (42.10±12.66). The scores of PCS were lower in caregivers with children aged 6 to 18 years (B = -1.783, 95%CI -3.279 to -0.287, P = 0.020), children with emotional instability (B = 2.719, 95%CI 1.254 to 4.184, P < 0.001), female caregivers (B = -3.765, 95%CI -6.578 to -0.953, P = 0.009), and caregivers who were relatively dissatisfied with the policy (B = 1.973, 95%CI 0.367 to 3.578, P = 0.016); and were higher in caregivers with children with speech disabilities (B = 3.463, 95%CI 0.053 to 6.873, P = 0.047). The types of disabilities of children (B_hearing = 9.465, 95%CI 5.107 to 13.823, P < 0.001; B_undetermined = 5.999, 95%CI 1.558 to 10.441, P = 0.008), playmates of children (B = 2.626, 95%CI 0.352 to 4.901, P = 0.024), education level of caregivers (B_{high middle school} = -4.701, 95%CI -8.028 to -1.374, P = 0.006; B_{high school} = -3.610, 95%CI -6.604 to -0.615, P = 0.018), family size (B = 2.616, 95%CI 0.479 to 4.753, P = 0.017) and per capita monthly income (B _{< 5000 Yuan}= -6.572, 95%CI -9.136 to -4.008, P < 0.001; B_{5000 to < 10000 Yuan} = -4.932, 95%CI -7.544 to -2.319, P < 0.001) were associated with the scores of MCS. Conclusion:The quality of life, especially the mental health, of caregivers of children with disabilities is poor. The influencing factors cover multiple dimensions such as caregivers, children, family and social environment.

Objectives:To systematically analyze the framework and contents of World Health Organization (WHO) policy and action strategies on rehabilitation using the theory of WHO health service components, to explore the theoretical bases, methodology, framework and core elements of WHO's international rehabilitation policy. Methods:WHO has launched rehabilitation-related policy documents, mainly including Rehabilitation in Health Systems, Rehabilitation in Health Systems: Guide for Action, Rehabilitation Indicator Menu: a tool accompanying the Framework for Rehabilitation Monitoring and Evaluation (FRAME), Template for Rehabilitation Information Collection (TRIC): a tool accompanying the Systematic Assessment of Rehabilitation Situation (STARS), and established systems of international rehabilitation policy architecture system. Using content analysis, this study analyzed in detail the theoretical basis and methodology of international rehabilitation policy, the policy framework, and the core elements of the action strategy and priority areas of rehabilitation service development in perspective of WHO six building blocks of health system, namely leadership and governance, financing, human resources for health, service delivery, medical technology, and health information systems. Results:WHO rehabilitation policy is developed based on WHO's theories of person-centered health services, social determinants of health, and functioning, disability and health of International Classification of Functioning, Disability and Health. WHO rehabilitation policy recognized that the development of rehabilitation was an important pathway achieving United Nations 2030 Sustainable Development Goals 3, ensure healthy lives and promote well-being for all at all ages, i.e. Unlversal Health Coverage. This paper systematically analyzed WHO's international policy framework, action strategies, and development areas, content and priorities in six major areas: leadership and governance, financing, human resources for health, service delivery, medicine and technology, and health information systems. WHO rehabilitation policies advocates to develop national rehabilitation plans, to establish and improve rehabilitation leaderships and the development of mechanism and capacity of rehabilitation governance, to develop multiple approaches of rehabilitation financing, to integrate rehabilitation into health service system, provides different levels of rehabilitation services in the health service continuum, and to build networks of service delivery, to train professionals, to foster rehabilitation information system within health system, to enhance service quality and service coverage, to focus on key areas and priority programs to meet the diverse needs of different populations, and achieve universal health coverage; to include assistive technology into the rehabilitation service system as a field of medicine and technology; and to collect information on functioning and rehabilitation needs, outcomes and impacts of rehabilitation services in the health information system, and conduct evidence-based researches on rehabilitation systems. Conclusion:The framework and contents of WHO's international rehabilitation policies have systematically reviewed at the macro, meso, and micro levels with the perspective of WHO six building blocks of the health system. The goal of rehabilitation development is to achieve universal rehabilitation coverage. The conceptual theories of rehabilitation are based on the theories of people-centered health services and social determinants of health. Rehabilitation is an important initiative to achieve the United Nations 2030 Sustainable Development Goals. The international rehabilitation health policy system is built on six major areas of rehabilitation: leadership and governance, rehabilitation financing, rehabilitation human resources, rehabilitation service delivery, rehabilitation-related medicine and technology, and rehabilitation and health information system. The policy and action strategies for rehabilitation development, as well as specific implementation paths and methods, at macro, meso and micro levels: theory and policy, policy action, and implementation methods and tools have been reviewed and discussed. The implementation of the WHO rehabilitation policies advocates to take the following actions: strengthening the leadership, governance, planning and coordination capacity of rehabilitation services; constructing a reasonable rehabilitation financing mechanism and raising necessary funds for rehabilitation; improving the training and guarantee mechanism of rehabilitation human resources; enhancing the professional capacity of rehabilitation personnel, improving the capacity of rehabilitation service delivery and improving service quality; improving the quality and accessibility of assistive products and assistive technology services; establishing health information system covering functioning, disability and rehabilitation, and conducting scientific researches on rehabilitation.
