Summary

Introduction

Bladder exstrophyeepispadias complex (BEEC) comprises a spectrum of anterior midline congenital malformations, involving the lower urinary tract. BEEC is usually sporadic, but families with more than one affected member have been reported, and a twin concordance study supported a genetic contribution to pathogenesis. Moreover, diverse chromosomal aberrations have been reported in a small subset of individuals with BEEC. The commonest are 22q11.2 microduplications, identiﬁed in approximately 3% of BEEC index cases.

Objectives

We aimed to reﬁne the chromosome 22q11.2 locus, and to determine whether the encompassed genes are expressed in normal developing and mature human urinary bladders.

Results

Using DNA from an individual with CBE, the 22q11.2 duplicated locus was reﬁned by identiﬁcation of a maternally inherited 314 kb duplication (chr22:21,147,293e21,461,017), as depicted in this image. Moreover, the eight protein coding genes within the locus were found to be expressed during normal developing and mature bladders. To determine whether duplications in any of these individual genes were associated with CBE, we undertook copy number analyses in 115 individuals with CBE without duplications of the whole locus. No duplications of individual genes were found.

Discussion

The current study has reﬁned the22q11.2locus associated with BEEC and has shown that the eight protein coding genes are expressed in human bladders both during antenatal development and postnatally. Nevertheless, the precise biological explanation as to why duplication of the phenocritical region of22q11 confers increased susceptibility to BEEC remains to be determined. The fact that individuals with CBE without duplications of the whole locus also lacked duplication of any of the individual genes suggests that in individuals with BEEC and duplication of the 22q11.2 locus altered dosage of more than one gene may be important in BEEC etiology.

Conclusions

The study has reﬁned the 22q11.2 locus associated with BEEC and has shown that the eight protein coding genes within this locus are expressed in human bladders.

Abstract：Since the publication of the first domestic expert consensus on the application of negative pressure wound therapy （NPWT） in burn surgery in 2017， both the types of techniques and the scope of clinical applica⁃tions have significantly expanded. In particular， a substantial body of high-quality evidence has accumulated regarding its role in promoting the healing of various acute and chronic wounds and in preventing surgical site infections. To integrate the latest research findings and clinical experience both domestically and internationally，standardize operational protocols， and enhance treatment efficacy， a multidisciplinary group of domestic experts in wound repair jointly developed this updated consensus. This consensus brings together insights from multiple domestic experts in wound-related multidisciplinary fields， incorporates the latest research advances， adheres to rigorous evidence-based medicine principles， and employs systematic review methodology. It focuses on core issues related to NPWT， including technical classifications， indications， parameter optimization， and complica⁃tion management. The working group systematically searched relevant literature in databases including PubMed，Web of Science， IEEE Xplore， and the China National Knowledge Infrastructure （CNKI） published between 2015 and 2025， retrieving a total of 791 articles. After deduplication， screening， and applying inclusion criteria （clinical studies， randomized controlled trials， meta-analyses， and relevant consensus documents），210 articles were ultimately included for evidence synthesis and evaluation. This consensus aims to provide clinicians in wound repair-related disciplines with unified， actionable treatment protocols and technical standards based on the latest evidence. The content fully integrates the current status and needs of clinical practice in China， with the goal of promoting the rational， standardized， and efficient application of NPWT nationwide， ultimately benefiting a greater number of patients.
