Article Abstract
Objective: To explore the clinical significance of platelet closure time (PCT) in patients with multiple myeloma (MM).
Methods: Peripheral blood samples of 50 newly diagnosed MM patients treated in our hospital from July 2018 to November 2019 and 34 healthy persons underuent physical at the same time were collected. PCT induced by collagen/epinephrine (CEPI) and collagen/adenosinediphosphate (CADP) in peripheral blood were detected by PFA-200，and the clinical data included age, sex, leukocyte count, hemoglobin level, platelet count and level of serum creatinine, cystatin c, blood calcium, β-microglobulin (β-MG), bone marrow plasma cells, light chain protein, as well as the MM types, ISS stage of patients were collected.
Results: The level of PCT in MM patients was significantly higher than that in healthy persons; the level of PCT were significantly increased with the increasing of ISS stage in newly diagnosed MM patients; After chemotherapy with bortezomib/dexamethasone (BD), the level of PCT in 15 patients who were responded to the treatment was significantly lower than those before treatment.
Conclusion: The platelet closure time is abnormal in MM patients, moreover, relates to the progress of the disease. It has an important clinical significance for the evaluation of diagnostic stage and therapeutic efficacy evaluation of MM patients.

Comparison of Endoscopic Pilonidal Sinus Treatment Combined with Platelet-Rich Plasma and Excision with Primary Closure in Pediatric Patients: A Retrospective Comparative Cohort Study on Short-Term Outcomes.

Background: Pilonidal sinus disease (PSD) is a common condition in adolescents, often resulting in recurrence, prolonged recovery, and significant discomfort. Although multiple surgical approaches exist, the optimal treatment for pediatric patients remains unclear. This study aimed to compare the short-term outcomes of endoscopic pilonidal sinus treatment combined with platelet-rich plasma application (EPSIT+PRP) and excision with primary closure (EPC) in children and adolescents with PSD.

Follicular unit extraction (FUE) has become a leading technique in hair transplantation, yet optimal management of the donor area remains a clinical challenge. This systematic review analyzes intraoperative and postoperative interventions applied to the donor area in FUE hair transplantation, with a focus on both clinical outcomes and the cellular and molecular mechanisms involved in tissue repair, inflammatory response, and regenerative processes. A comprehensive literature search was conducted in PubMed and EMBASE (January 2000-June 2025), identifying clinical studies that evaluated donor area treatments and reported outcomes related to healing, inflammation, infection, and patient satisfaction.

The platelet protease-activated receptor 4 (PAR4) threonine 120 (Thr120) allele is an activating allele associated with reduced aspirin response in vitro. Aspirin is recommended in high-risk pregnancies to prevent preeclampsia and preterm birth. We evaluated the impact of PAR4 genotype on aspirin response in pregnancy, as measured by platelet function assay 100 (PFA-100) epinephrine closure time, and perinatal outcomes.

Introduction: Blood derivatives may enhance wound healing, but each possesses distinct characteristics and has yielded varying outcomes in patient treatment. This research seeks to examine the efficacy of conditioned plasma (CP) using polylactic acid (PLA) coated beads and to compare it with CP using bare beads and platelet-rich plasma (PRP) in the context of acute wound healing.
Methods: Blood was collected from 7 volunteer donors in three tubes containing ACD anticoagulant, PLA coated, or bare beads and incubated for 6 h at 37 °C.

Radiotherapy, while effective in cancer treatment, can lead to side effects, such as radiodermatitis with potential long-term consequences including telangiectasias, ulceration and fibrosis of the skin, eventually resulting in impaired wound healing. In this study, we analyzed whether the healing of such challenging wounds can be improved by nanofat (NF). NF is generated by mechanical emulsification and filtration of fat samples and, thus, is a random mixture of adipose-derived stem cells, microvascular fragments, extracellular matrix components and growth factors.
