Diabetes mellitus(DM)stands as a chronic metabolic ailment predominantly characterized by elevated blood glucose lev-els,stemming from either a resistance to insulin or aberrations in insulin secretion.The ensuing persistent hyperglycemia,a direct con-sequence of pancreatic β-cell devastation,acts as a catalyst for a myriad of complications,inclusive of extensive neuropathies.The dis-ease has substantial prevalence and mortality rates,underscoring the gravity of its impact on public health.Dental pulp stem cells(DPSCs)are readily obtainable,and they exhibit a profound capacity for self-renewal,multi-lineage differentiation,and vigorous pro-liferation.Remarkably,DPSCs can differentiate into pancreatic β-cells,subsequently participate in insulin secretion and play a pivotal role in immune modulation.This has achieved notable advancements in the therapeutic domain,particularly in the treatment of chronic diseases.Furthermore,DPSCs harbor the potential to mitigate symptoms in patients afflicted with type 1 diabetes.They navigate this therapeutic pathway through mechanisms that involve suppressing autoimmunity,modulating inflammatory responses,and counteracting oxidative stress.This article meticulously reviews the biological characteristics inherent to DPSCs and explores their multifaceted thera-peutic potential in addressing DM and its associated complications.Through this endeavor,the article aims to contribute to the refine-ment and enhancement of DM management strategies.

【Objective】 To evaluate the safety and effectiveness of Perioperative Transfusion Trigger Score (POTTS) in guiding surgical patients blood transfusion intraoperatively and postoperatively. 【Methods】 A total of 900 patients(perioperative Hb 60~100 g/L) from December 2017 to March 2021 were collected, including 251 males and 649 females, with ASA grading Ⅰ~Ⅳ, and randomly divided into experimental group and controls. In the experimental group, the allogeneic RBC transfusion trigger(Hb threshold) and transfusion units in anemia patients was determined by POTTS. While those in the controls were decided by physicians according to current guidelines concerning transfusion. The proportion and units of allogeneic RBC transfusion, the incidence of postoperative complications, the mortality of hospitalization and discharge for 4 weeks, Hb value, healing of surgical incision, ICU admission rate and ICU length of stay, length of hospitalization, etc were recorded. 【Results】 The proportion of allogeneic RBC transfusion in the experimental group(35.3%)were less than the controls(42.2%)(P<0.05). The units of allogeneic RBC transfused, incidence of postoperative complications and mortality in hospital and 4 weeks after surgery, healing of surgical incision (grade A/ grade B/ grade C), the Hb level 24 h after surgery and at discharge, the ICU admission rate and ICU length of stay, length of hospitalization were not significantly different between the groups. 【Conclusion】 The peri-operative allogeneic red blood cells transfusion guided by POTTS can reduce the proportion of allogeneic RBC transfusion, and is safe and effective.
