RESUMO
Objective:To construct training indexes of post competency of dental hygienist, and to provide objective basis for the establishment of the index system of the transition from dental nurse to dental hygienist in the future.Methods:The relevant literature of post competency of dental hygienist was searched from the databases such as PubMed, Medline, Web of Science, China National Knowledge Internet, Wanfang database. The search time was from the establishment of the database to March 2021. The expert letter inquiry questionnaire was designed through preliminary consultation.Delphi expert consultation was conducted for 20 dental experts from Beijing city, Chongqing city, Jiangsu province, Sichuan province, Jilin province from May to November 2021, and model indexes and weight assignment of post competency of dental hygienist were determined.Results:Three rounds of Delphi expert consultation were conducted, the effective recoveries of the questionnaires were 100%, the expert authority coefficients were 0.81, 0.81, 0.83, respectively, the coefficient of variation of expert consultation was 0.000-0.386, 0.000-0.300 and 0.000-0.250, respectively, the coordination degree of expert opinions in the third round of consultation was 0.679, 0.428 and 0.389 (all P<0.01). The formed training indexes of post competency of dental hygienist included 4 first-level indexes, 20 second-level indexes and 60 third-level indexes. Conclusions:The training index system of post competency of dental hygienist in this study is scientific, reliable, and practical, to provide reference for training and assessment of post competency of dental hygienist and objective basis for establishing the indexes system of dental nurse to dental hygienist in the future.
RESUMO
Background and Objectives@#Psoriasis is a chronic inflammatory skin disease, which the mechanisms behind its initiation and development are related to many factors. DMSCs (dermal mesenchymal stem cells) represent an important member of the skin microenvironment and play an important role in the surrounding environment and in neighbouring cells, but they are also affected by the microenvironment. We studied the glucose metabolism of DMSCs in psoriasis patients and a control group to reveal the relationship among glucose metabolism, cell proliferation activity，and VEC (vascular endothelial cell) differentiation in vitro, we demonstrated the biological activity and molecular mechanisms of DMSCs in psoriasis. @*Methods@#and Results: We found that the OCR of DMSCs in psoriatic lesions was higher than that in the control group, and mRNA of GLUT1 and HK2 were up-regulated compared with the control group. The proliferative activity of DMSCs in psoriasis was reduced at an early stage, and mRNA involved in proliferation, JUNB and FOS were expressed at lower levels than those in the control group. The number of blood vessels in psoriatic lesions was significantly higher than that in the control group (p＜0.05), which the mRNA of VEC differentiation, CXCL12, CXCR7, HEYL and RGS5 tended to be increased in psoriatic lesions compared to the control group, in addition to Notch3. @*Conclusions@#We speculated that DMSCs affected local psoriatic blood vessels through glucose metabolism, and the differentiation of VECs, which resulted in the pathophysiological process of psoriasis.
RESUMO
Objective@#To study the distribution of sub-health and occupational stress as well as their correlation among middle school teachers in Tianjin, then provide evidences for prevention and control of the status of sub-health.@*Methods@#A total of 3 522 middle school teachers from six districts of Tianjin were recruited with stratified cluster sampling strategy for the investigation of Sub-Health Measurement Scale version 1.0 (SHMS V1.0) and Occupational Stress Inventory-Revised Edition (OSI-R) .@*Results@#Detection rate of sub-health status among Tianjin middle school teachers was 58.55%. Men had significantly lower sub-health detection rate (55.19%) than women (59.71%) . Sub-health detection rate increased with age (P<0.05) , the sub-health detection rate among middle school teachers more than 50 years old was the highest (66.84%) . The mean score of OSI-R was 403.18±41.80 with the scores of 176.00±21.05, 103.17±17.53, and 124.02±20.28 for ORQ, PSQ, PRQ, respectively, which showed significantly difference compared with the occupational stress norm of China (P<0.001) . The mean scores of OSI-R, ORQ, PSQ, PRQ in different health status were significantly different (P<0.001) . The partial correlation analysis between the scores of sub-health and occupational stress of middle school teachers showed that the scores of occupational role and personal strain were negatively correlated with the scores of sub-health state (P< 0.001) , while, there was significantly positive correlation between the scores of personal resource and the scores of sub-health state (P<0.001) .@*Conclusion@#Sub-health detection rate of middle school teachers in Tianjin is higher. Effective measures should be taken to appropriately mitigate the occupational stress level of middle school teachers, increase personal resources, and scientific and effective health guidance and education should be strengthened.
