2018 Chinese Pediatric Cardiology Society (CPCS) guideline for diagnosis and treatment of syncope in children and adolescents

Abstract: Syncope belongs to the transient loss of consciousness (TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society (CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association (CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association (CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association (CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association (BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and head-up tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.

Acupuncture for stress urinary incontinence in adults

Abstract: Background The use of acupuncture for stress urinary incontinence is increasing in frequency, especially in Asian area. However, its effectiveness and side effects have not been evaluated. Objectives To assess the effectiveness and side effects of acupuncture for stress urinary incontinence in adults. Search methods We searched the Cochrane Incontinence Group Specialised Register (searched 28 January 2013), EMBASE, AMED, Chinese Biomedical Literature Database (CBM), Chinese Acupuncture Trials Register and China National Knowledge Infrastructure (CNKI) (all searched 20 February 2013). In addition, we searched the reference lists of relevant articles and contacted authors and trialists in the field. Selection criteria Randomised and quasi-randomised controlled trials of acupuncture interventions without other treatments for the management of stress urinary incontinence for adults. Data collection and analysis Two review authors independently assessed eligibility, trial quality and extracted data. We meta-analysed data where appropriate. Main results We identified 17 possibly eligible studies but only one small trial with 60 women met our inclusion criteria. The trial compared acupuncture versus midodrine, a drug for treating hypotension. The risk of bias was high as there was no concealment of randomised allocation, and there was no blinding of assessment of outcome. In addition, it was not possible to blind participants or health providers to the interventions. The statistical methods were not described. More women improved in the acupuncture group (73% with acupuncture versus 33% with midodrine; risk ratio (RR) 2.20, 95% confidence interval (CI) 1.27 to 3.81) but the cure rates were low and not statistically significantly different (13% versus 7%; RR 2.00, 95% CI 0.40 to 10.11). There were adverse events in the drug group only. Authors' conclusions The effect of acupuncture for stress urinary incontinence for adults is uncertain. There is not enough evidence to determine whether acupuncture is more effective than drug treatment.

B7-H3 as a promising target for cytotoxicity T cell in human cancer therapy

Abstract: Targeting B7-H3 over-expressed tumor cells with anti-B7-H3 monoclonal antibodies inhibits tumor growth. Here we demonstrated the expression of B7 family homologue 3 (B7-H3) in a wide range of human tumor cells and further investigated whether B7-H3 could be served as a target for T-cell mediated immunotherapy against human cancers. The specific cytotoxic activity of activated T cell (ATC) armed with a novel anti-CD3 x anti-B7-H3 bispecific antibody (B7-H3Bi-Ab) against tumor cell was evaluated in vitro and in vivo. In contrast with unarmed ATC, an increase in cytotoxic activity of B7-H3Bi-armed ATC against tumor cells was observed at effector/target (E/T) ratios of 5:1, 10:1, and 20:1. Moreover, B7-H3Bi-armed ATC secreted more IFN-γ, TNF-α and IL-2 than unarmed ATC. Infusion of B7-H3Bi-armed ATC inhibited tumor growth in severe combined immunodeficiency (SCID) xenograft models, along with a significant survival benefit. Therefore, treatment with novel B7-H3Bi-armed ATC will be a promising strategy for current cancer immunotherapy.

Evaluation of Electronic Healthcare Databases for Post-Marketing Drug Safety Surveillance and Pharmacoepidemiology in China

Abstract: Electronic healthcare databases (EHDs) are used increasingly for post-marketing drug safety surveillance and pharmacoepidemiology in Europe and North America. However, few studies have examined the potential of these data sources in China. Three major types of EHDs in China (i.e., a regional community-based database, a national claims database, and an electronic medical records [EMR] database) were selected for evaluation. Forty core variables were derived based on the US Mini-Sentinel (MS) Common Data Model (CDM) as well as the data features in China that would be desirable to support drug safety surveillance. An email survey of these core variables and eight general questions as well as follow-up inquiries on additional variables was conducted. These 40 core variables across the three EHDs and all variables in each EHD along with those in the US MS CDM and Observational Medical Outcomes Partnership (OMOP) CDM were compared for availability and labeled based on specific standards. All of the EHDs’ custodians confirmed their willingness to share their databases with academic institutions after appropriate approval was obtained. The regional community-based database contained 1.19 million people in 2015 with 85% of core variables. Resampled annually nationwide, the national claims database included 5.4 million people in 2014 with 55% of core variables, and the EMR database included 3 million inpatients from 60 hospitals in 2015 with 80% of core variables. Compared with MS CDM or OMOP CDM, the proportion of variables across the three EHDs available or able to be transformed/derived from the original sources are 24–83% or 45–73%, respectively. These EHDs provide potential value to post-marketing drug safety surveillance and pharmacoepidemiology in China. Future research is warranted to assess the quality and completeness of these EHDs or additional data sources in China.
