And the stratum corneum, the outermost layer of human epidermis, plays a central role in the interaction between the cutaneous tissue and the external environment. The horny layer, and more generally the whole skin layers, avoid the penetration of harmful exogenous agents, produce molecules named anti-microbial peptides which impact the composition of the cutaneous microbiota, regulate the internal corporal temperature, avoid the water loss from the inside of the body and constitute an incredible efficient anti-oxidant network. Nevertheless, nowadays, the skin is more and more solicited by the different elements of the cutaneous exposome, including atmospheric pollution and solar radiations, which can cause a dramatic acceleration of the skin ageing process. As a consequence, due to the multifunctional protective role of the skin, during the recent decade the cosmetic industry invested massively in the development of new raw materials and end-products (dermo-cosmetics) able to preserve an optimal state of the skin regarding the external environment. Based on their physical-chemical properties thermal spring waters, which are extremely rich in inorganics ions, are interesting and powerful candidates to be part, as integral component, of new efficient dermo-cosmetic formulations dedicated to protect the skin from the external stimuli. The aim of the present work was to investigate and characterize the activity of Jonzac thermal spring water on the skin. Using different models, we proved for the first time that Jonzac thermal spring water reinforces the barrier function of the skin by modulating the expression of key markers including filaggrin and human beta defensin 2 on ex vivo human skin. The ex vivo and in vivo hydration activity, by Raman spectroscopy and corneometry respectively, has been also demonstrated. We have also shown that Jonzac thermal spring water ameliorates significantly the cutaneous microrelief in vivo. To conclude, we characterize the soothing effect of Jonzac thermal spring water by the analysis of histamine release in Substance P treated skin explants and by measuring the redness of the skin following UV exposure of the skin in vivo. We observed that both parameters decreased following a preventive treatment of the skin with Jonzac thermal spring water. Taken together our results indicate that Jonzac thermal spring water is a promising and powerful dermo-cosmetic which can be used to preserve an optimal state of the cutaneous tissue.展开更多

METHODS: The animal model of stress-related nonalcoholic fatty liver which is more in line with the modern social and clinical conditions was established by the method of chronic restraint compound high-fat feed. AST and ALT were detected by automatic biochemical analyzer. Serum cortisol and TNF-a were detected by radioimmunoassay. The relative expression of Nr3 c1 mRNA was detected by real-time quantitative PCR. RESULTS: Compared with the blank group, the scores of open field test, Nr3 c1 mRNA decreased, and AST, ALT, FFA were significantly increased in model group. Compared with model group, the open field test scores, Nr3 c1 mRNA increased,and Cor, AST, FFA, LDL, TNF-a, were significantly decreased in SNS group. CONCLUSIONS: "Soothing the liver method" can exert its therapeutic effect on stress-related non-alcoholic fatty liver on neuroendocrine-metabolic level.展开更多

Methods: the patients with end-stage leukemia in Linfen People's Hospital of Shanxi Province were selected as the research object. The collection period was from June 2019 to June 2020. A total of 80 patients were randomly divided into two groups with 40 patients in each group. Relaxation nursing (observation group) and routine nursing (control group) were selected respectively. After the nursing, the indexes of the two groups of patients were analyzed and compared. Results: the nursing satisfaction of the observation group was significantly different from that of the control group (p < 0.05). After nursing, the anxiety score and depression score of the observation group were significantly different from those of the control group (P < 0.05). The incidence of infection events in the observation group was significantly higher than that in the control group (p < 0.05). In the comparison of quality of life scores between the two groups, the observation group was significantly higher (p < 0.05). Conclusion: the application of soothing care in patients with end-stage leukemia can effectively improve the relationship between nurses and patients, relieve the negative emotions of patients, improve the comfort level of patients, improve physical and mental symptoms, and improve the quality of life.展开更多

文摘In order to search an appropriate evaluation method for the soothing effect of cosmetics,the LPS-induced macrophage model,SDS-stimulated zebrafish embryos model and the clinical assessment were used.The results showed that the concentration of NO and IL-6 was significantly reduced in LPS-induced RAW264.7 cells when applied to two essences.The inhibition rate of NO-release was 85.87%and 84.57%,while IL-6 was 44.18%and 38.76%,respectively.Furthermore,the spontaneous rotating of zebrafish embryos was significantly decreased to 51.85%and 76.54%in SDS-stimulated zebrafish embryos model.In the 28 days of clinical assessment,the concentration of hydration was significantly increased to 55.56%and 39.61%,while the erythrodesis was significantly decreased to 4.75%and 6.68%.This indicates that the three evaluation methods of soothing efficacy in this research were effective,and can be used in the evaluation of cosmetics.
文摘Pancreatic pseudocyst, whose clinical feature is small simple cyst, is a common local complication of acute pancreatitis and will not need surgery in ordinary circumstances. However, some cases could appear secondary disorders related to the location of the cyst and the role of decomposition enzymes of content, such as cyst rupture moving into the abdomen, bleeding, cystic infection, compression and internal fistula formation with adjacent organs and so on^([1]). But the spleen-related complications resulting from it are rare. There was 1 patient with pancreatic pseudocyst admitted to Dongfang Hospital Affiliated to Beijing University of Chinese Medicine and the report is as follows.
文摘OBJECTIVE: To study the therapeutic effects of "soothing the liver method" on stress-related non-alcoholic fatty liver and its treatment mechanism on neuroendocrine-metabolic level. METHODS: The animal model of stress-related nonalcoholic fatty liver which is more in line with the modern social and clinical conditions was established by the method of chronic restraint compound high-fat feed. AST and ALT were detected by automatic biochemical analyzer. Serum cortisol and TNF-a were detected by radioimmunoassay. The relative expression of Nr3 c1 mRNA was detected by real-time quantitative PCR. RESULTS: Compared with the blank group, the scores of open field test, Nr3 c1 mRNA decreased, and AST, ALT, FFA were significantly increased in model group. Compared with model group, the open field test scores, Nr3 c1 mRNA increased,and Cor, AST, FFA, LDL, TNF-a, were significantly decreased in SNS group. CONCLUSIONS: "Soothing the liver method" can exert its therapeutic effect on stress-related non-alcoholic fatty liver on neuroendocrine-metabolic level.
文摘Objective: to evaluate the effect of palliative care on the quality of life of patients with end-stage leukemia. Methods: the patients with end-stage leukemia in Linfen People's Hospital of Shanxi Province were selected as the research object. The collection period was from June 2019 to June 2020. A total of 80 patients were randomly divided into two groups with 40 patients in each group. Relaxation nursing (observation group) and routine nursing (control group) were selected respectively. After the nursing, the indexes of the two groups of patients were analyzed and compared. Results: the nursing satisfaction of the observation group was significantly different from that of the control group (p < 0.05). After nursing, the anxiety score and depression score of the observation group were significantly different from those of the control group (P < 0.05). The incidence of infection events in the observation group was significantly higher than that in the control group (p < 0.05). In the comparison of quality of life scores between the two groups, the observation group was significantly higher (p < 0.05). Conclusion: the application of soothing care in patients with end-stage leukemia can effectively improve the relationship between nurses and patients, relieve the negative emotions of patients, improve the comfort level of patients, improve physical and mental symptoms, and improve the quality of life.
