RESUMO

BACKGROUND: To further clarify the acne profile of Chinese adult women, we included 1,156,703 adult women. An artificial intelligence algorithm was used to analyze images taken by high-resolution mobile phones to further explore acne levels in Chinese adult women. METHOD: In this study, we assessed the severity of acne by evaluating patients' selfies through a smartphone application. Furthermore, we gathered basic user information through a questionnaire, including details such as age, gender, skin sensitivity, and dietary habits. RESULTS: This study showed a gradual decrease in acne severity from the age of 25 years. A trough was reached between the ages of 40 and 44, followed by a gradual increase in acne severity. In terms of skin problems and acne severity, we have found that oily skin, hypersensitive skin, frequent makeup application and unhealthy dietary habits can affect the severity of acne. For environment and acne severity, we observed that developed city levels, cold seasons and high altitude and strong radiation affect acne severity in adult women. For the results of the AI analyses, the severity of blackheads, pores, dark circles and skin roughness were positively associated with acne severity in adult women. CONCLUSIONS: AI analysis of high-res phone images in Chinese adult women reveals acne severity trends. Severity decreases after 25, hits a low at 40-44, then gradually rises. Skin type, sensitivity, makeup, diet, urbanization, seasons, altitude, and radiation impact acne. Blackheads, pores, dark circles, and skin roughness are linked to acne severity. These findings inform personalized skincare and public health strategies for adult women.

RESUMO

BACKGROUND: To better compare the progression of dark circles and the aging process in Chinese skin. A total of 100 589 Chinese males and 1 838 997 Chinese females aged 18 to 85, without facial skin conditions, and who had access to a smartphone with a high-resolution camera all took selfies. METHOD: Using a smartphone application with a built-in artificial intelligence algorithm, facial skin diagnostic evaluated the selfies and score the severity of the dark circles with four other facial indicators (including skin type, Pores, Acne vulgaris, and Blackheads). Basic information was collected with online questionnaire, including their age, gender, skin sensitivity, and dietary habits. RESULTS: In users between the age of 18 and 59, the prevalence of comprehensive, pigmented, and structural type of dark circles all rose with age. However, between the age of 60 and 85, the intensity of all types of dark circles diminished. Besides, vascular dark circles progressively worsen from the age of 18 to their peak at 39, and then gradually decline with age. Females typically have more pronounced black circles under their eyes than males in China. Bad eating habits, urbanization, regular cosmetics use, and sensitive skin positively correlate with severe dark circles. Vascular, comprehensive dark circles were worse in spring. Both pigmented and structural dark circles were worse in the summer. The results indicated that the intensity of dark circles was influenced by oily skin, wide pores, severe blackheads, and severe acne. CONCLUSIONS: Chinese men and women differed noticeably in the prevalence of each face aging indicator and the appearance of aging dark circles. Selfies could be automatically graded and examined by artificial intelligence, which is a quick and private method for quantifying signs of facial aging and identifying major problems for different populations. Artificial intelligence would assist in the development of individualized preventive and therapeutic interventions.

RESUMO

OBJECTIVE: To explore whether coal tar pitch smoke extract (CTP) induced pyroptosis in human bronchial epithelial cells (BEAS-2B). METHODS: BEAS-2B cells were treated with different concentrations of CTP (1, 3 µg/ml) for 8h and 24 h, respectively. Lactic dehydrogenase (LDH) activity and interleukin-1 beta (IL-1ß) levels in the supernatants of cell culture media were measured with LDH activity or human IL-1ß ELISA kit, respectively. The activity of Caspase-1 was measured with Caspase-1 colorimetric assay kit. RESULTS: The activity of caspase-1 in 1 and 3 µg/ml CTP groups were (9.29 ± 0.30) and (8.67 ± 0.59) µmol/ml respectively which were both significantly increased compared to that (7.42 ± 0.59) µmol/ml in the control group (P < 0.05) after 8 h exposure, but there was no significant difference in the activity of LDH and levels of IL-1ß in the cell culture media among the CTP and control groups. 24 h after exposure, the activity of LDH in the CTP (1, 3 µg/ml) groups were (1323.03 ± 28.53) and (1148.45 ± 16.42) U/dl respectively which were significantly higher than that (1091.93 ± 26.64) U/dl in the control group (P < 0.05), and the levels of IL-1ß in the CTP (1 and 3 µg/ml) groups were (125.37 ± 25.00) pg/ml and (92.04 ± 19.09) pg/ml respectively which were significantly higher than that (46.20 ± 14.43) pg/ml in the control group (P < 0.05), but there was no significant difference in the activity of Caspase-1 among CTP and control groups (P < 0.05). CONCLUSION: CTP treatment induced early increase in caspase-1 activity followed by the increase in LDH activity and IL-1 levels, indicative of pyroptosis in human bronchial epithelial cells.

RESUMO

OBJECTIVE: To investigate the in vitro release and transdermal behaviors of mumps cataplasm of complex prescription. METHODS: The improved Franz difficusion was used and the concentration of drugs was detected. DCS was determined by HPLC and flavanoid contents were determined by UV. RESULTS: The accumulation skin permeation percentage of DCS and flavanoid was 32% and 21%, respectively, the in vitro release percentage of DCS and flavanoid was 47% and 42%, respectively. CONCLUSION: The transdermal behavior of mumps cataplasm of complex prescription is an zero-order kinetics progress. The in vitro release behavior is in accordance with the Higuchi equation.
