Heparin-binding protein (HBP) is a pro-inflammatory granule protein released by activated neutrophils, known for its role in modulating vascular permeability and its pathological significance in infectious diseases. In recent years, HBP has garnered attention due to its immune-activating effects in contexts such as sepsis, acute lung injury and organ transplantation. It has been proposed as a potential biomarker for early detection of infection and inflammation. While preliminary progress has been made in animal studies, clinical evidence remains limited. Therefore, this article focuses on the mechanism of action of HBP in transplantation-related complications, explores its potential pathways for predicting infection risk, mediating ischemia-reperfusion injury and rejection, and evaluates the feasibility of intervention strategies such as neutralizing antibodies, heparin derivatives and albumin. The pivotal role of HBP in regulating inflammatory responses post-transplant may offer a novel target for postoperative infection monitoring and personalized therapeutic interventions.

Objective To explore the utilization of laparoscopy in the diagnosis and treatment of Meckel’s diverticulum in children. Methods A total of 16 children with Meckel’s diverticulum underwent laparoscopic procedures between June 1999 and February 2003. With the help of celioscopy, the focus of the intestines is detected and pulled out through the umbilical port. The wedge resection of diverticulum or enterectomy with anastomosis was then performed. Results The operative time was 75 ～ 150 min, with a mean of 92 min. The patients began to take food on the third postoperative day. No operative complications occurred. The postoperative hospital stay was 5～7 d, with a mean of 5.8 d. Follow-up for 4～44 months (mean, 19.4 months) in the 16 patients showed no intestinal adhesion. Conclusions Laparoscopy is safe and effective in the diagnosis and treatment of Meckel’s diverticulum.
