Objective To explore the prevention and treatment of acute kidney injury (AKI) after gastrointestinal surgical procedures.Method We retrospectively analyzed the data of patients underwent gastrointestinal surgery in recent 2 years in the First Affiliated Hospital of Kunming Medical University and the First People's Hospital of Yunnan Province. Result The incidence of AK1 was 2.1%. Elderly patients with basic diseases had poorer prognosis than non-elderly patients. Conclusion In the patients after gastrointestinal Surgery, early rehydration, diuresis, ant-infection and preventive hemodialysis can achieve the goal of prevention and treatment of acute kidney injury in early stage.

Objective To explore the influencing factors of late diagnosis for newly diagnosed HIV/AIDS positive patients in Guangxi in 2015.Methods The CD4 + T lymphocytes count which was first detection for newly diagnosed HIV/AIDS positive patients in Guangxi during 2015 was collected.Data were statistically analyzed.Results We collected 8 586 newly diagnosed HIV/AIDS whose median CD4+ T lymphocytes counts was 237.5 cells/μl,and 43.12％ of them had less than 200 cells/μl.Gender,age,occupation,marriage,nation,education,route of transmission,types of testing and region had effects on late HIV diagnosis(all P ＜ 0.05).Logistic analysis found that risk factors associated with the late diagnosis of HIV were male(OR =1.851,95％ CI:1.673-2.048),migrant worker (OR =1.387,95％ CI:1.242-1.549),education below middle and secondary school(OR =1.619,95％ CI:1.400-1.873),currently married(OR =1.207,95％ CI:1.075-1.354),divorced or widowed(OR =1.508,95％ CI:1.309-1.738).Voluntary testing was a protective factor.Conclusions The prevalence the late diagnosis of HIV was high in Guangxi in 2015,it is crucial for related departments to enhance the testing and screening effort for HIV/AIDS.

Objective:To construct the whole-process intelligent management system for preventing PICC-related bloodstream infections and explore its effect in preventing PICC-related bloodstream infections.Methods:From January 2021 to December 2022, patients with PICC admitted to Wenzhou People' s Hospital were selected as the research subject, the patients from January to December 2021 were divided into the control groups, the patients from January to December 2022 were divided into the observation group. The whole-process intelligent management system for preventing PICC-related bloodstream infections was constructed and applied with artificial intelligence, this study compared the incidence of PICC-related bloodstream infections and the implementation rate of PICC whole-process bundled management projects before and after system application.Results:The incidence of PICC-related bloodstream infections in the control group was 0.55‰ (14/25 674), while the incidence in the observation group was 0.20‰ (5/25 226), with a statistically significant difference (χ 2=4.110, P<0.05). The implementation rates of PICC whole-process bundled management projects in the control group and observation group were 74.04% (2 319/3 132) and 92.11% (2 885/3 132), respectively, with a statistically significant difference (χ 2=363.782, P<0.01) . Conclusions:The whole-process intelligent management system for preventing PICC-related bloodstream infections constructed optimizes the prevention and treatment process of PICC-related bloodstream infections, effectively ensures the implementation of nursing interventions and monitoring measures, and reduces the incidence of PICC-related bloodstream infections.

Objective To investigate the incidence and severity of enamel demineralization during clear aligner treatment and provide reference for clinical medical nursing work.Methods A total of 151 patients(3 507 teeth)undergoing clear aligner treatment in our hospital from 2015 to 2022 were collected.The enamel demineralization before and after treatment was compared,and the enamel demi-neralization index(EDI)was calculated to evaluate the severity of demineralization.The incidence and severity of enamel demineraliza-tion were analyzed statistically,and the differences among different genders,ages and dental positions were compared.Results Enam-el demineralization occurred in 84 patients during treatment,with an incidence rate of 55.63%.Gender and treatment time had no effect on the incidence,and the incidence of adolescent patients was higher than that of adult patients.Among the investigated 3 507 teeth,601 teeth had enamel demineralization,and the incidence rate was 17.14%.The incidence of maxillary anterior teeth and mandibular posterior teeth was higher;the incidence of right teeth was significantly higher than that of left teeth,and the incidence of teeth with ad-hesive attachments was also significantly increased.88%of the enamel demineralization lesions were 1－2 degrees,and the degree of enamel demineralization was similar in male and female patients.But the degree in adolescents was significantly higher than that in adult patients.The average EDI value of maxillary anterior teeth was significantly higher than that of mandible,but that of maxillary posterior teeth was significantly lower than that of mandible.The average EDI value of right teeth was significantly higher than that of left.Conclusion The incidence of enamel demineralization is high in the process of clear aligner treatment,and teenagers are suscep-tible to it.The demineralization of teeth is significantly different among different tooth positions,and adhesive attachments will increase the risk of enamel demineralization.Therefore,medical staff should take active and effective measures in the prevention and treatment of enamel demineralization.
