【摘要】 目的 观察光子嫩肤合并左旋维生素C导入治疗面部黄褐斑的临床疗效。 方法 2008年3月-2009年5月，105例黄褐斑患者随机分为两组，治疗组53例，用光子嫩肤治疗2个疗程后用左旋维生素C导入，1次/周，持续2个月；对照组52例，单纯使用光子嫩肤治疗后进行防晒、护肤治疗2个月。 结果 治疗组有40例黄褐斑消失，13例色斑明显减淡；对照组有12例黄褐斑消失，26例色斑明显减淡，11例色斑减淡，3例无效。两组疗效比较，差异有统计学意义（Plt;0.05）。 结论 光子嫩肤合并左旋维生素C导入治疗面部黄褐斑安全、方便、疗效好，患者易于接受。【Abstract】 Objective To observe the clinical efficacy of the treatment of facial melasma by intense pulsed light (IPL) photorejuvenation combined with vitamin C. Methods From March 2008 to May 2009, 105 patients with facial melasma were randomly divided into two groups. In the treatment group, there were 53 patients who were treated with vitamin C after IPL photorejuvenation once a week for two months. For the 52 patients in the control group, sunscreen and skin care treatment were carried out after IPL treatment for two months. Results In the treatment group, 40 patients’ melasma disappeared and 13 patients’ melasma dodged obviously. In the control group, 12 patients’ melasma disappeared and pigmentation existed more or less in 40 patients. Conclusion Treatment for facial melasma by IPL photorejuvenation combined with vitamin C is safe, convenient, and have good effect, which can be easily accepted by the patients.
Objective To assess the prevalence of malnutrition in patients with advanced non-small cell lung cancer (NSCLC) using the Global Leadership Initiative on Malnutrition (GLIM) criteria, analyze its associated factors, and explore the adverse effects of malnutrition on advanced NSCLC patients in multiple aspects. Methods Patients with NSCLC who were hospitalized for the first time in the Department of Oncology, Shangjin Hospital, West China Hospital, Sichuan University between January and December 2021 were retrospectively selected as the study objects. Malnutrition assessment was carried out in all patients according to GLIM criteria, and the current situation and related factors of malnutrition were analyzed. The Barthel index scale was used to compare the daily activity ability between the malnourished group and the non-malnourished group, the Quality-of-Life Questionnaire-Core 30 scale was used to compare the quality of life between the two groups, and the adverse reactions of the two groups were compared by the hospital information system course records. Results According to GLIM diagnostic criteria, 134 of 285 patients (47.0%) were diagnosed with malnutrition. The results of binary multiple logistic regression analysis showed that age [60-69 vs. <60 years old: odds ratio (OR)=2.323, 95% confidence interval (CI) (1.277, 4.397); ≥70 vs. <60 years old: OR=10.816, 95%CI (4.185, 27.959)], previous medical history [OR=2.740, 95%CI (1.313, 5.717)], and albumin level [OR=0.905, 95%CI (0.848, 0.965)] were associated with malnutrition in patients with advanced NSCLC (P<0.05). The daily activity ability and quality of life in the malnourished group were significantly worse than those in the non-malnourished group (87.57±12.48 vs. 91.82±6.77, P<0.05; 76.22±11.52 vs. 83.96±9.75, P<0.05), and the incidence of adverse reactions in the malnourished group was higher than that of the non-malnourished group (50.7% vs. 31.8%, P<0.05). Conclusions The prevalence of malnutrition in patients with advanced NSCLC is high, and advanced age, previous medical history and albumin are related factors of malnutrition in patients with advanced NSCLC. Combined malnutrition may have adverse effects on mobility, quality of life and adverse effects of anti-tumor therapy in advanced NSCLC patients.
