Objective To investigate preventive measures and pathogenic related factors of periodontitis. Methods A total of 138 patients with periodontitis from August 2012 to March 2014 in our department were selected as the experi-mental group. Meanwhile 138 healthy cases matched with the patients within 2 years age difference in the same regions were selected as the control group. Questionnaire survey was used to inquire the basic information, educational status, economic income, acquisition of knowledge in periodontal disease, brushing habits, negative life events and so on. The differences in results between two groups were compared. Results Among 138 patients with periodontitis, there was 1087 disease parts on maxillaries, 872 parts on mandibles, 1243 parts on molars, and 876 parts on anterior teeth and bicuspids. According to Amaitage standard, 138 patients with periodontitis, the rate of mild to moderate periodontitis patients was 81.16% (112 cases), and the rate of severe periodontitis was 18.84% (26 cases). Acquisition of knowledge in periodontal disease, smoking, the frequency and sustained time of brushing per day, negative life events and mouth care between two groups showed statistical significance(P<0.05). There was no significant difference between two groups in age, gender and educational status(P>0.05). Non conditional Logistic regression results showed that: independent pathogenic risk factors of periodontitis included acquisition of knowledge in periodontal disease, the frequency and sus-tained time of brushing per day, negative life events and regular mouth care, and regular mouth care ranked first among these factors(the odds ratio=3.102, P<0.05). Conclusion Periodontitis is the result of interaction of multiple risk factors, therefore, comprehensive measures especially regular mouth care should be adopted to prevent the occurrence of peri-odontitis.

Objective To investigate the effect of tigecycline on coagulation function and to provide a reference for the clinical rational use of tigecycline.Methods The data of patients treated with tigecycline in Shanghai Tenth People's Hospital between June 2019 and December 2023 by retrospective analysis.Statistical analysis was performed by collecting data on patients'basic information,routine coagulation parameters and thromboelastogram(TEG)parameters before and after the use of tigecycline.Results Activated partial thromboplastin time,prothrombin time and thrombin time were prolonged and fibrinogen levels were decreased with the use of tigecycline in 41 patients,the differences were statistically significant(P＜0.05).There was no significant difference in levels of coagulation factor activation time,clot formation rate parameter,maximum angle of tangency,maximum amplitude of elastography and coagulation index after treatment with tigecycline(P＞0.05).Conclusion For patients with suspected coagulation abnormalities after tigecycline administration,a comprehensive assessment of coagulation should be made by combining routine coagulation indexes with TEG.

Objective:To construct an ICU-acquired weakness training program for ICU nurses based on Gagne learning theory.Methods:From March to August 2021, the ICU-acquired weakness training program for ICU nurses was constructed through literature review, semi-structured interview, and Delphi expert consultation.Results:Among two rounds of expert consultation, 16 and 20 valid questionnaires were recovered respectively, and the expert authority coefficients were 0.897 and 0.903, and the Kendall harmony coefficients were 0.312 and 0.323, respectively, and the differences were all statistically significant ( P<0.01) . The ICU-acquired weakness training program for ICU nurses included 3 first-level indicators (training objectives, training process and content, training form) , 16 second-level indicators, and 41 third-level indicators. Conclusions:The ICU-acquired weakness training program for ICU nurses based on Gagne learning theory is scientific and reliable, and can provide a reference for ICU nurses' ICU-acquired weakness training.
