Objective To investigate the relationship of the expression characteristics of CD4 + CD25 + Foxp3 + Treg cells and CD4 + IL-17 + Th17 cells and the progress of the elderly patients with laryngeal cancer.Methods Sixty elderly patients diagnosed as laryngeal cancer in our hospital from January 2013 to June 2014 were chosen.Among them,28 cases had lymph node metastasis and 32 without.Thirty cases without laryngeal diseases were chosen as control.The peripheral blood of elderly patients with laryngeal cancer and normal controls was extracted.The expression levels of Treg and Th17 cells in all groups were detected with flow cytometry,and the expression changes of Foxp3,RORγt in peripheral blood mononuclear cell (PBMC) were detected with real time quantitative PCR.Results Compared with the control group,CD4 + CD25 + Foxp3 + Treg and CD4 + IL-17 + Th17 cell percentage,Treg and Th17 cells specific transcription factor Foxp3,RORγt expression levels in elderly laryngeal cancer patients without lymph node metastasis were significantly higher (t=9.817,P=0.018; t=12.120,P=0.009; t=6.090,P=0.023; t=7.130,P=0.028).Compared with elderly laryngeal cancer patients without lymph node metastasis,Treg and Th17 cell percentage and Foxp3,RORγt expression levels were significantly increased (t =9.070,P =0.014; t =12.140,P =0.009; t =10.130,P =0.009 ; t =13.070,P =0.008),and the ratios of Th17/Treg and Foxp3/RORγt were significantly lower (2.401 ± 0.614 vs 3.763 ± 0.959 ; 0.401 ± 0.075 vs 0.563 ± 0.091 ; t =9.070,P =0.014 ; t =11.140,P =0.007) in elderly laryngeal cancer patients with lymph node metastasis.Conclusion In elderly patients with laryngeal cancer,Treg cells and Th17 cells imbalance is positively correlated to disease progression.Therefore,monitoring and correcting the expression levels of Treg and Th17 cells may be important for the diagnosis,treatment and prognosis of the elderly patients with laryngeal cancer.

Objective:To understand the output of research and education of clinical key Specialties in Henan Province, to analyze the current situation and existing problems, and to provide scientific evidence and suggestions for the improvement of specialist ability.Methods:Through the questionnaire survey to collect the scientific research data of key specialties from 2015 to 2019, apply Epidata 3.0 to input the data, use SPSS 21.0 software to carry out test and Mann Whitney U test, and carry out a comparative analysis of the national and provincial clinical key specialty discipline leaders, medical talent team, academic, scientific research and education output in Henan Province. Results:Academic literacy and scientific research ability of leaders of national and provincial key clinical specialties in Henan Province are equal. However, there is still a big gap in scientific research and education ability between national and provincial key clinical specialties in Henan Province.Conclusions:The provincial key clinical specialties need to improve the ability of scientific research and education in a more holistic way, further strengthen the medical talents team, and focus on the exchange of high-level academic platform and the cultivation of research talents.

Objective:To evaluate the comprehensive strength of the specialties included in the medical service capacity improvement project of Henan provincial medical and health institutions, analyze the influencing factors, and provide scientific basis for the specialty construction.Methods:A total of 52 specialties were included in the project. According to the content of construction assessment and acceptance, the questionnaire was designed and filled in by the persons in charge of the specialties from the aspects of basic conditions, medical technical team, medical service ability, medical quality, scientific research and teaching ability. TOPSIS method was used to evaluate the comprehensive strength of specialty, and the main influencing factors were analyzed by single factor analysis, Mann-Whitney U test, correlation analysis and multiple stepwise regression analysis. Results:The research and teaching ability of the specialties had the strongest correlation with the comprehensive strength of the specialties. The scientific research and teaching ability was strongly related to the medical service ability. The number of people holding the post of academic institutes at or above provincial level, the number of industry standards or national guidelines, the number of academic conferences hosted at or above the provincial level, the number of postgraduate training, the number of papers published in SCI and core journals were the main influencing factors of scientific research and teaching ability.Conclusions:It is necessary to improve the level of scientific research and teaching in key specialty to promote the improvement of medical service ability. We should pay more attention to the construction of high-level talents, the cultivation of research-oriented talents, the application of new medical technology and original research.

OBJECTIVE: To understand the distribution of allergens in patients with allergic rhinitis (AR) in Quanzhou, for the diagnosis, prevention and treatment. METHOD: Twenty standardized allergen underwent skin prick testing (skin prick test, SPT) were used for 1236 patients with suspected AR patients in Quanzhou, and the different age, gender and severity in patients with allergen distribution differences of positive rate were analyzed. RESULT: The top 5 allergens with positive skin tests were D. pteronyssinus (66.7%), D. farinae (65.5%), Blattodea (32.8%), Sea crab (18.2%), and Sea lobster (16.8%). The positive rate of SPT in the minor groups and adult groups had significant difference (P < 0.05). Gender difference between the positive rate of SPT had no significant difference (P > 0.05). There was significant difference between the positive rate in patients with a family history and history of asthma and patients without above two history (P < 0.05). CONCLUSION Dust Mite, Blattodea, Sea crab. Sea lobster are the most important allergens in quanzhou. Different ages of the patients with SPT positive rates vary, a family history, history of asthma patients with positive rate is higher than patients without a family history of asthma history, high positive rate.
