Development and validation of a prospective questionnaire for assessing oily sensitive skin.

BACKGROUND: Skin type has a strong influence on how sensitive skin develops, with oily skin accounting for a larger proportion of sensitive skin. However, there has not been a scientifically sound questionnaire for determining oily sensitive (OS)-type skin in prior studies. OBJECTIVES: In order to identify OS-type skin in the general population, we therefore intend to create an OS-type skin evaluation questionnaire, develop various thresholds through data analysis and classify skin based on two dimensions of sensitivity and oiliness. METHODS: A questionnaire with questions regarding subjects' basic information, skin oiliness and skin sensitivity was given to each individual who participated in the study (n = 1297). To define the thresholds for OS-type skin, receiver-operating characteristic (ROC) curves were generated. The results of the lactic acid stinging test (LAST) and noninvasive instrument information obtained were compared with the thresholds mentioned above to verify the effectiveness of this tool. RESULTS: According to the ROC curves, questionnaire cut-off values of 11.5, 20.5 and 29.5 can be used to detect mildly, moderately and severely sensitive skin, respectively. In addition, the questionnaire cut-off values of 22.5 and 31.5 can be used to detect moderately and severely oily skin, respectively. According to our study, the four sensitive-skin groups' LAST scores differed significantly from one another, while the skin sebum levels differed significantly between the three oily groups. Additionally, the EI and LAST scores were significantly correlated with skin sensitivity levels, whereas sebum, moisture and EI were positively correlated with skin oiliness levels. CONCLUSIONS: We developed an OS-type skin evaluation questionnaire that has been tested and shown scientifically to be a promising method for evaluating OS-type skin and to completely examine the traits of sensitive and oily skin.

CONTEXTE: Le type de peau a une forte influence sur la sensibilité de la peau, avec une peau grasse représentant une plus grande proportion de peaux sensibles. Cependant, il n'y a pas eu de questionnaire scientifiquement fiable pour déterminer le type de peau sensible grasse (OS) dans les études antérieures. OBJECTIFS: Afin d'identifier la peau grasse et sensible dans la population générale, nous avons donc l'intention de créer un questionnaire d'évaluation de la peau grasse et sensible, d'élaborer différents seuils par l'analyse des données et de catégoriser à partir de deux dimensions de sensibilité et d'état huileux. MÉTHODES: Un questionnaire comprenant des questions sur les informations de base des sujets, la sécrétion de sébum de la peau et la sensibilité cutanée a été distribué à chaque individu ayant participé à l'étude (n = 1297). Pour définir les seuils des peaux grasse et sensible, des courbes sensibilité/spécificité (receiver-operating characteristic, ROC) ont été générées. Les résultats du test de picotement à l'acide lactique (LAST) et les informations obtenues à l'aide d'instruments non invasifs ont été comparés aux seuils mentionnés ci-dessus pour vérifier l'efficacité de cet outil. RÉSULTATS: Selon les courbes ROC, des valeurs limites du questionnaire de 11,5, 20,5 et 29,5 peuvent être utilisées pour détecter une sensibilité cutanée légère, modérée et sévère, respectivement. De plus, les valeurs de seuil du questionnaire de 22,5 et 31,5 peuvent être utilisées pour détecter respectivement une peau modérément et sévèrement grasse. Selon notre étude, les scores LAST des quatre groupes à peau sensible différaient significativement les uns des autres, tandis que les taux de sébum cutané différaient significativement entre les trois groupes à peau grasse. De plus, les scores IE et LAST étaient significativement corrélés avec les taux de sensibilité cutanée, tandis que le sébum, l'humidité et l'IE étaient positivement corrélés avec les taux de graisse cutané. CONCLUSIONS: Nous avons développé un questionnaire d'évaluation de la peau grasse et sensible qui a été testé et qui s'est avéré scientifiquement être une méthode prometteuse pour évaluer la peau grasse et sensible et pour examiner complètement les caractéristiques de la peau sensible et grasse.

Young Chinese female body skin pigmentation map: A pilot study.

BACKGROUND: Most studies have discussed variations in facial skin colour based on age, gender, and anatomical site within a specific ethnic group. However, skin pigmentation on the body is also a concern for many people. AIM: The aim of this study is to gather baseline data for Chinese young females, conduct a comprehensive assessment of body skin pigmentation, and create a body skin pigmentation map. METHOD: Individual type angle (ITA°) was registered by CL 400 and melanin index (MI) was registered by MX 18 in 100 body points of 20 Chinese females. A total of 12,000 measurements were recorded. RESULT: Our results showed significant differences among the symmetrical points on both sides of the body, including the clavicle, inner wrists, groin, inner ankle, elbow, armpit, waist side, the space between the thumb and index finger, instep, back shoulder, and popliteal space. Of all the points tested on the body, the points with the most severe skin pigmentation were the back of the neck, the heel, the elbow, and the popliteal space. CONCLUSION: This is the first comprehensive study of skin pigmentation conducted on the human body. In young Chinese women, the points with the most severe skin pigmentation were the back of the neck, heels, elbows, and the popliteal space.

Cellulose-Based Intelligent Responsive Materials: A Review.

Due to the rapid development of intelligent technology and the pursuit of green environmental protection, responsive materials with single response and actuation can no longer meet the requirements of modern technology for intelligence, diversification, and environmental friendliness. Therefore, intelligent responsive materials have received much attention. In recent years, with the development of new materials and technologies, cellulose materials have become increasingly used as responsive materials due to their advantages of sustainability and renewability. This review summarizes the relevant research on cellulose-based intelligent responsive materials in recent years. According to the stimuli responses, they are divided into temperature-, light-, electrical-, magnetic-, and humidity-responsive types. The response mechanism, application status, and development trend of cellulose-based intelligent responsive materials are summarized. Finally, the future perspectives on the preparation and applications of cellulose-based intelligent responsive materials are presented for future research directions.

Traditional Chinese Medicine Decoctions Improve Longevity Following Diagnosis with Stage IV Esophageal Squamous Cell Carcinoma: A Retrospective Analysis.

OBJECTIVE: Traditional Chinese medicine (TCM) is an ancient form of personalized medicine and may improve morbidity and mortality in patients with esophageal cancer. This retrospective study aimed to evaluate the utility of TCM in the treatment of stage IV esophageal squamous cell carcinoma (SCC). METHODS: We collected the medical records of patients with stage IV SCC admitted to Henan Provincial Hospital of Traditional Chinese Medicine and Linzhou Hospital of Traditional Chinese Medicine between July 2017 and June 2020. We used univariate and multivariate analyses to determine if the use of TCM improved patient prognosis. Moreover, cluster analysis was used to classify the patients according to TCM syndrome type and identify the most frequently used combinations of remedies. RESULTS: After that 402 patients were included in PSM, of which 196 (48.8%) were treated with traditional Chinese medicine. TCM prolonged the survival time of patients with stage IV esophageal SCC (P=0.084), and was an independently associated with prognosis as demonstrated by Cox multivariate regression analysis [risk ratio (RR) =0.543, 95% confidence interval (CI): 0.390-0.755, P<0.001]. Association analysis revealed 75 cases (38.26%) had obstruction of phlegm and qi syndrome, 53 cases (27.04%) had phlegm and blood stasis syndrome, 38 cases (19.39%) had yang-qi deficiency syndrome, and 30 cases (15.31%) had heat retention and fluid consumption syndrome. CONCLUSION: Treatment with TCM derived therapies may increase the survival time of patients with stage IV esophageal SCC. Since these patients were diagnosed with different TCM syndromes, individualized TCM therapy is essential for improving symptoms and survival.

High DSCC1 Level Predicts Poor Prognosis of Lung Adenocarcinoma.

PURPOSE: To evaluate the role of DSCC1 in LUAD. PATIENTS AND METHODS: Based on TCGA and GTEx, the Wilcoxon rank-sum test was used to compare the expression differences of DSCC1 between the normal samples of GTEx combined TCGA and the unpaired tumor samples of TCGA, and to compare DSCC1 expression values between tumor tissues and paired normal LUAD tissues in the TCGA cohort. Kruskal-Wallis rank-sum test, Wilcoxon rank-sum test, and logistics regression were used to compare the relationship between the expression of DSCC1 and the clinicopathological parameters. The biological function of DSCC1 was annotated by GSEA and ssGSEA, while Kaplan-Meier and Cox regression analysis were used to evaluate the prognostic value of DSCC1. Furthermore, the time-dependent ROC curve was used to analyze the diagnostic efficacy of DSCC1 in LUAD. RESULTS: We downloaded the RNA-Seq data of 513 LUAD cases. The expression of DSCC1 was significantly correlated with T stage (OR = 1.04(1.02-1.07), P = 0.002), pathological stage (OR=1.03 (1.01-1.05), P = 0.008) and TP53 status (OR=1.10 (1.07-1.14), P < 0.001). The high expression of DSCC1 was significantly correlated with DSS (HR=1.56 (1.07-2.26), P = 0.021) and OS (HR=1.53 (1.14-2.05), P = 0.004). Moreover, ROC curve analysis (AUC=0.845, CI (0.820-0.870)) indicated DSCC1 as a potential diagnostic molecule for LUAD. In the group with high DSCC1 expression phenotype, down-regulation of EGFR signal, reduction of IL-6 deprivation, cell cycle, and p53 signal pathway were significantly abundant. Spearman correlation analysis showed that the expression of DSCC1 was positively correlated with the infiltration of Th2 cells, T Helper cells. CONCLUSION: Our results suggest that DSCC1 may be an important biomarker for the treatment of LUAD.

[Molecular typing of enteroviruses from healthy children in the border areas of Yunnan Province and Myanmar and the genetic characteristics of ECHO7 and ECHO13 in 2009].

To explore the enteroviruses surveillance among healthy children under 15 years old in the border areas of Yunnan Province and Myanmar in 2009. The stool samples were collected from the healthy children under 15 years old who came from the border areas of Myanmar and Yunnan Province, virus isolation and sequencing were conducted for all the 271 samples. 6 strains of polioviruses (PVs) were detected from 271 stools with an isolation rate of 2.8%, which belonged to vaccine strains and 24 non-polioviruses (NPVs) were detected with an isolation rate of 8.9%. 24 NPVs belonged to human enterovirus group B (HEV-B) with 6 serotypes, HEV-A, HEV-C and HEV-D viruses were not isolated. Among them, 13 NPVs were E7 (54.17%) and 5 NPVs were E13 (20.83%). Our results showed that the enterovirus carrying rate in the border areas of Yunnan province was higher than the rate of routine acute flaccid paralysis (AFP) detection system. The HEV-B viruses were the only enteroviruses isolated. The phylogenetical analysis showed that Echovirus 7(E7) and 13 (E13) exhibited genetic polymorphism.
