Screening and evaluation of sunscreen cosmetics for sensitive facial skin / 中华皮肤科杂志

Objective:To screen and evaluate sunscreen cosmetics for sensitive facial skin.Methods:From June to August in 2019, 40 subjects with positive lactic acid sting test were recruited from the staff of Chongqing Traditional Chinese Medicine Hospital, and subjected to human skin closed patch testing with 4 kinds of sunscreen cosmetics for sensitive skin (marked as products Ⅰ, Ⅱ, Ⅲ, Ⅳ respectively) separately. Then, the 40 subjects were equally divided into 2 groups to apply 2 sunscreen products with relatively higher safety (according to the above closed patch testing results) on the face respectively. Erythema, edema and desquamation were evaluated at baseline, 2 and 4 weeks after application of the 2 products, and non-invasive measurement methods were used to detect transepidermal water loss (TEWL) , stratum corneum hydration, skin melanin content and skin sebum content. In additon, the 2 products were applied on the back of the subjects separately, and an ultraviolet solar simulator was used to determine the sun protection factor (SPF, n = 12) and protection factor of UVA (PFA, n = 11) . Measurement data were compared using paired t test and one-way analysis of variance, and nonparametric data were compared using Wilcoxon signed rank test. Results:Patch testing showed that only 1 subject developed a grade 1 reaction to the sunscreen product Ⅲ, no subjects showed positive reactions to the product Ⅳ, and the safety of products Ⅲ and Ⅳ was higher than that of the other 2 products. Subjective safety evaluation revealed that the degree of erythema after 4-week application of products Ⅲ and Ⅳ was significantly lower than that before application (Wilcoxon signed rank test, Z = 4.73, 4.82 respectively, both P < 0.05) . Objective efficacy evaluation revealed that the TEWL, stratum corneum hydration and skin melanin content significantly differed among different time points (baseline, after 2- and 4-week application of products Ⅲ and Ⅳ, all P < 0.05); after 4-week application of products Ⅲ and Ⅳ, the TEWL (30.05 ± 1.47, 30.37 ± 1.28 respectively) and skin melanin content (112.58 ± 7.34, 103.47 ± 5.48 respectively) were significantly lower than those before application (all P < 0.05) , and the stratum corneum hydration (62.35 ± 2.67, 63.72 ± 2.54 respectively) was significantly higher than that before application (both P < 0.05) . At week 4, the skin melanin content was significantly lower in the product Ⅳ group (103.47 ± 5.48) than in the product Ⅲ group (112.58 ± 7.34, t = 8.45, P < 0.05) . The SPF and PFA values of the product Ⅳ (51.8 ± 2.9, 10.1 ± 1.2 respectively) were both significantly higher than those of the product Ⅲ (31.5 ± 2.6, 7.4 ± 0.7, t = 15.34, 24.66, respectively, both P < 0.05) . Conclusion:Comprehensive application of closed patch testing, long-term application test and sun protection index determination can be used to screen and evaluate the safety and efficacy of sunscreen cosmetics for sensitive facial skin.

Objective To study the colonization rate and antibiotic resistance of group B Streptococcus (GBS) in gravidas during late pregnancy,and to evaluate the effectiveness of GBS screening in late pregnancy and intrapartum antibiotic prophylaxis (IAP) for the prevention of neonatal early-onset GBS disease (EOGBS).Methods A retrospective study was conducted to analyze the colonization rate and antibiotic resistance pattern of GBS in 14 204 gravidas who were screened for GBS at 35-37 gestational weeks during March 2016 to March 2018 in the University of Hongkong-Shenzhen Hospital (HKU-SZH).Differences in the incidence of EOGBS before and after GBS screening and IAP were analyzed using Chi-square or Fisher's exact test.Results Among the 14 204 gravidas,2 027 cases were GBS positive with a colonization rate of 14.27％.Incidence rates of EOGBS before and after GBS screening were 0.6‰ (4/6 356) and 0.07‰ (1/14 403),respectively (Fisher's exact test,P=0.033).GBS isolates were 100％ (2 027/2 027) sensitive to penicillin and vancomycin.Resistance rates to clindamycin and erythromycin were 67.2％(1 363/2 027) and 65.7％ (1 332/2 027),respectively.Conclusions Routine GBS screening in late pregnancy and IAP can significantly decrease the incidence of EOGBS.Penicillin is the optimal choice for prevention and treatment of GBS infection.

Correlation between HLA-B~* 13:01 allele and liver dysfunction in patients with occupational medicamentosa-like dermatitis due to trichloroethylene / 中国职业医学

OBJECTIVE: To explore the correlation between human leukocyte antigen( HLA)-B~* 13 : 01 allele and liver dysfunction in patients with occupational medicamentosa-like dermatitis due to trichloroethylene( OMDT). METHODS: Twenty patients with OMDT were chosen as study subjects by using a convenient sampling method. The sequence-based genotyping method was used for detecting HLA-B~* 13 : 01 allele in the DNA samples from peripheral blood of all study subjects. The serum levels of total protein,albumin,total bilirubin,direct bilirubin and alanine aminotransferase,aspartate aminotransferase and alkaline phosphatase activities in patients were examined. The correlation between the number of HLA-B~* 13 : 01 alleles and the liver function indices was also analyzed. RESULTS: There were 16 patients carrying HLA-B~* 13: 01 allele. The serum total protein in the HLA-B~* 13: 01 carriers was higher than that of non-carriers( P < 0. 05). The serum total protein was positively correlated with the number of patients carrying HLA-B~* 13: 01 alleles( P < 0. 05). CONCLUSION: The degree of liver function damage in OMDT patients may be related to carrying the HLA-B~* 13: 01 allele.
