Objective: To analyze the clinical efficacy of hematoporphyrin monomethyl ether photodynamic therapy (HMME-PDT) in treating port-wine stains (PWS), and its clinical operation skills and operation essentials.
Method: A total of 16 cases of PWS with negative HMME skin test results were included in this study. Their treated areas were exposed and injected with 5mg/kg HMME, and then irradiated under 532nm LED green light (produced by Wuhan YaGe LED1 modified machines), with the irradiation power density between 80 and 100mW/cm. Each light spot was irradiated for 20-25min. After one treatment, the clinical efficacy and post-treatment reactions at each treated area were observed.
Result: Under standard operation, two of the 16 cases were cured (12.5%) after one HMME-PDT treatment, eight cases indicates a good efficacy (50.0%), four cases showed alleviation (25.0%), while two cases displayed no efficacy (12.5%), indicating an one-time response rate of 87.5%. Pain was reported during treatment, and significant post-treatment edema was observed at the treated areas; And no allergy or other adverse reaction were reported.
Conclusion: In adherence to operation standards and operation essentials during treatment, HMME-PDT shows a satisfactory clinical efficacy in treating PWS.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a second-line treatment with curative potential for leukemia patients. However, the prognosis of allo-HSCT patients with disease relapse or graft-versus-host disease (GvHD) is poor. CD4 or CD8 conventional T (Tconv) cells are critically involved in mediating anti-leukemic immune responses to prevent relapse and detrimental GvHD.

Background: Major decision-making self-efficacy (MDMSE) is an important indicator of students' ability to make effective decisions in specialty selection. It has implications for students' personal growth and career counselling interventions. While the previous MDMSES has been widely used in the context of China's New College Entrance Examination reform, the increased choice of majors and advancement of career planning necessitate a new scale to assess high school students' MDMSE levels.
