目的：评估血细胞分离机单采制备自体富血小板血浆（PRP）治疗雄激素性脱发（AGA）的疗效及安全性。方法：纳入31例AGA患者，采用单采技术制备血小板浓度803~1669×10?/L的自体PRP，激活后行头皮注射治疗3次（间隔1个月）。于基线（T1）及每次治疗后1、2、3个月（T2~T4）评估毛发密度与不良反应。结果：患者均为男性。毛发密度由T1的（111.77±12.00）根/cm2升至T4的（133.74±16.34）根/cm2（均P＜0.001）。医师评估有效率80.6%，患者满意率74.2%。主要不良反应为注射部位出血、肿痛及灼热感，均自行缓解；1例出现额部及眼睑明显水肿，5 d后消退。结论：单采自体PRP治疗AGA疗效确切且安全。规范控制PRP制备质量及血小板浓度有助于优化疗效。

Objective: To evaluate the clinical efficacy and safety of autologous platelet-rich plasma (PRP) prepared via apheresis using a blood cell separator for the treatment of androgenetic alopecia (AGA). Methods: A total of 31 patients with AGA who completed the study were enrolled. Autologous PRP with a platelet concentration of 803-1669×10?/L was prepared using apheresis technology. After activation, the PRP was administered via intralesional scalp injections for a total of 3 sessions at 1-month intervals. Hair density changes and adverse reactions were evaluated at baseline (T1) and at 1, 2, and 3 months after the initial treatment (T2-T4). Results: All included patients were male. Hair density significantly increased from (111.77±12.00) hairs/cm2 at baseline to (133.74±16.34) hairs/cm2 at T4 (all P<0.001). The clinician-evaluated effective rate was 80.6%, and the patient satisfaction rate was 74.2%. The primary adverse reactions included hemorrhage, swelling, burning sensation, and transient pain at the injection site, all of which resolved spontaneously. Notably, 1 patient developed marked edema in the forehead and eyelids, which subsided spontaneously after approximately 5 days. Conclusion: Autologous PRP prepared via apheresis is effective and safe for the treatment of AGA. Standardized quality control of PRP preparation and platelet concentration may contribute to further optimizing the therapeutic outcomes.

[Abstract]Objective:To explore the impact of refined intraoperative instrument management by operating room nurses on the efficiency and safety of HVR surgery.Methods:The study subjects included 110 patients with VHD who underwent HVR treatment at our hospital from June 2024 to May 2026, along with 22 instrument nurses who participated in the surgeries synchronously. Using the random number table method, the enrolled patients and nurses were divided into a control group (55 patients, 11 nurses) and an experimental group (55 patients, 11 nurses). Nurses in the conventional group implemented routine instrument management during surgery, while nurses in the experimental group implemented zoned and refined instrument management during surgery. The surgical efficiency, perioperative safety events of the two groups of patients, as well as the work efficiency and intraoperative instrument management of the surgeries participated by the nurses in the two groups were compared.Results:Under different instrument management modes, the aortic occlusion time, extracorporeal circulation time, intraoperative non-essential waiting time, and total surgical time of patients in the experimental group were all lower than the control group (t=8.817，5.730，20.609，9.632; P<0.05). The incidence of perioperative safety events in the experimental group was 9.09% (5/55) lower than that in the control group 25.45% (14/55) (x2=5.153; P<0.05). The instrument placement time, instrument delivery response time, number of surgical interruptions, instrument sorting time, and instrument handover time of nurses in the experimental group were lower than those in the control group (t=3.347，6.505，5.971，3.795，5.838; P<0.05). The error rate of nurses in the experimental group was lower than the control group (x2=5.238; P < 0.05).Conclusion:Refined intraoperative zone-specific instrument management by instrument nurses enhances surgical efficiency for HVR patients and reduces the risk of perioperative safety incidents, thereby positively impacting the quality of instrument care provided by nurses and preventing instrument-related adverse events.

[Abstract]Objective:To explore the application effect and safety of ultrasound bone scalpel and high-speed turbine mobile phone in surgical procedures for patients with jaw cysts.Methods:A total of 100 patients with maxillary cysts who underwent curettage surgery in our hospital from January 2024 to June 2025 were selected for the study. The enrolled patients were randomly divided into a control group and an experimental group using the hidden envelope method, with 50 patients in each group. The conventional group used high-speed turbine mobile phones for bone removal during surgery, while the experimental group used ultrasonic bone knives for bone removal during surgery. The surgical conditions, postoperative pain and swelling, and incidence of complications during hospitalization were compared between the two groups of patients. Follow up for six months after surgery to compare the nerve damage and bone healing between the two groups of patients.Results:The intraoperative bleeding volume, postoperative 24-hour drainage volume, and bone cutting accuracy deviation of the experimental group were (30.59 ± 5.24) mL, (20.55 ± 5.28) mL, and (0.18 ± 0.05) mm, respectively, all lower than those of the control group [(40.19 ± 7.33) mL, (30.46 ± 6.45) mL, and (0.59 ± 0.12) mm] (t=7.534，8.407，22.301; P<0.05); The surgical time of the experimental group was similar to the control group (P>0.05). The VAS scores and swelling scores of the experimental group at 24, 48, and 72 hours after surgery were lower than the control group (t=4.403，3.354，12.986，4.610，2.911，14.888；; P<0.05). The incidence of complications during hospitalization in the experimental group was 4.00% (2/50) lower than the control group 18.00% (9/50) (x2=5.005; P<0.05).The NCV of the experimental group was higher than the control group at the1,3,6 months of follow-up, and TPD was lower than the control group (t=4.598，5.784，6.322，3.194，3.595，3.501; P<0.05). As of the end of follow-up, the osteogenic rate of the experimental group was (75.27 ± 8.14)% higher than the control group (68.18 ± 5.27)%. The bone defect area, wound healing time, and bone resorption were (55.29 ± 5.42)%, (3.22 ± 0.47) months, and (1.25 ± 0.36) mm, lower than the control group [(62.44 ± 7.51)%, (5.08 ± 1.33) months, and (2.49 ± 0.32) mm] (t=5.170，5.459，9.324，18.204; P<0.05).Conclusion:Compared with high-speed turbo phones, ultrasonic bone scalpel can reduce the risk of intraoperative bleeding in patients with jaw cysts and achieve precise bone removal. It can alleviate postoperative pain and swelling while greatly avoiding postoperative nerve damage, and has a positive impact on promoting bone healing in patients.

To evaluate the effectiveness of an intervention combining Root Cause Analysis (RCA)–based quality management and Psychological Capital (PsyCap) theory in reducing communication interruptions and improving communication quality and teamwork in surgical safety check teams. Methods: Eighty surgical team members from a tertiary hospital (January 2025 - December 2025.) were assigned to a control group or an intervention group according to operating room allocation (40 per group). The control group followed routine surgical safety check procedures, whereas the intervention group additionally received an RCA-guided workflow analysis and a PsyCap-based communication enhancement program. Post-intervention outcomes included communication interruption rate, execution quality and efficiency of safety checks, Psychological Capital Questionnaire (PCQ-24) scores, and TeamSTEPPS Teamwork Perceptions Questionnaire (T-TPQ) scores. Results: The intervention group demonstrated a significantly lower communication interruption rate compared with the control group (P＜0.05). Execution quality and communication efficiency were significantly improved in the intervention group (P＜0.001). PCQ-24 total and subscale scores were significantly higher in the intervention group than in the control group (P＜0.001), as were T-TPQ total and subscale scores (P＜0.001). Conclusion: Integrating RCA-based workflow optimization with PsyCap-oriented psychological and behavioral training can effectively enhance communication quality, reduce interruptions, and strengthen teamwork in surgical safety check teams. The combined model has strong applicability and potential for wider clinical promotion.
