Objective To analyze the epidemiological and pathogenic characteristics of acute respiratory in-fection in Yangpu District of Shanghai,and to provide scientific basis for the prevention and treatment of re-spiratory tract infection.Methods A total of 1 062 patients diagnosed with acute respiratory infection in the hospital from June 2023 to June 2024 were selected as the research objects.The nucleic acid of 13 pathogens in nasopharyngeal swabs of patients was detected and the positive rate was calculated.The positive rate of differ-ent age groups and seasons was analyzed.Results Among 1 062 patients,716 cases were detected positive,the total positive rate was 67.42%,of which 577 cases were single infection,the positive rate was 54.33%.The top five positive pathogens were Mycoplasma pneumoniae(MP,16.48%),human coronavirus(HCOV,9.42%),human rhinovirus(HRV,7.63%),human metapneumovirus(HMPV,5.46%)and parainfluenza vi-rus(HPIV,3.39%).A total of 139 cases were infected with multiple pathogens,with a positive rate of 13.09%.MP,HRV,and HCOV were the dominant pathogens,which were prone to multiple infections.A to-tal of 139 cases were infected with multiple pathogens,with a positive rate of 13.09%.MP,HRV,and HCOV were the dominant pathogens,which were prone to multiple infections.The total positive rate of respiratory pathogens in children was 86.38%,the positive rates of single infection and multiple infection were 65.12%and 21.26%,respectively,which were significantly higher than those in other age groups(P<0.05).Among the 577 children with single infection,MP and HRV were the main pathogens in children,MP and HCOV were the main pathogens in young and middle-aged patients,and HCOV and HRV were the main pathogens in the elderly patients.The total positive rate of pathogens was the highest in winter(69.88%),and the lowest in summer(49.54%).HRV had the highest positive rate in spring,HCOV had the highest positive rate in summer,MP had the highest positive rate in autumn,and influenza virus(including influenza A virus,influen-za A/H3N2 virus,influenza B virus)had the highest positive rate in winter(P<0.05).Conclusion MP,HCOV,HRV,HMPV and HPIV are the top five pathogens of acute respiratory tract infection in Yangpu dis-trict of Shanghai.The etiological characteristics were related to age and seasonality of patients.

Objective:To explore the characteristics of nursing-related research design types, implementation organizations, funding sources and research fields by analyzing the characteristics of nursing-related trials registered in the Chinese Clinical Trial Registry (ChiCTR) .Methods:We searched the nursing-related clinical trials registered in the ChiCTR database, and the search time was from the establishment of the database to May 25, 2020. The characteristics of registered nursing related trials were analyzed.Results:A total of 319 nursing-related trials were obtained, of which 268 trials were registered as pre-registration and 51 trials were supplementary registration. The number of trial registrations in Shanghai, Guangdong, Sichuan, Jiangsu and Beijing were greater than or equal to 25. The main source of funding was college funds, followed by local finance, self-financing and national finance. Among the registered trials, 239 (74.92%) were randomized controlled trials, and 27 were multi-center clinical trials, and 53 trials used the blind method, and 277 trials passed the review of the ethics committee. Research fields were widely distributed, mainly tumors, strokes and diabetes.Conclusions:The number of nursing-related trials registered in ChiCTR is increasing, but there are regional imbalances in the distribution of research, and the low proportion of funding from high-level funds. Relevant personnel are needed to improve the level of nursing research from many aspects such as nursing education, nursing management, research registration management and funding support.

Objective To investigate the relationship between wheezing and serum levels of 25-hydroxyvitamin D3.Methods 130 children with lower respiratory tract infection were selected as the subjects, the children with wheezing in group A([Abstract] Objective To investigate the relationship between wheezing and serum levels of 25-hydroxyvitamin D3.Methods 130 children with lower respiratory tract infection were selected as the subjects, the children with wheezing in group A(n=70),normal pneumonia (no wheezing) were group B(n=60); The healthy children who were examined in the hospital at the same period were selected as the control group (n=60). The serum levels of 25-hydroxyvitamin D3 were measured by ELISA in the control and hospitalized children. The pathogens and allergens of the two groups were also detected. Results The levels of serum 25-hydroxyvitamin D3 in group A and group B were (56.92±16.88) nmol/L, (70.68±21.96) nmol/L, respectively, which was significantly lower than that in control group (82.69±17.63) nmol/L, ( t=8.50, 3.30,P=0.00,0.00); compared with group A( t=3.85, P=0.00). The positive rate of group A was 65.71%, which was significantly higher than that of group B (35.00%, χ2=12.20,P=0.00). The positive rate of group A was 30.00% compared with the control group (35.00%, χ2=0.36,P=0.54). The serum level of 25-hydroxyvitamin D3 was 75.57% in group A, which was significantly higher than that in group B (60.00%,χ2=14.21, P=0.00). The positive rate of virus detection was 57.14% in 98 children with serum 25-hydroxy vitamin D3 level<75 nmol/L, which was significantly higher than that in serum 25-hydroxy vitamin D3 level≥75 nmol/L(18.75%, χ2=14.25, P=0.00). The positive rate of allergens in serum 25-hydroxy vitamin D3 level <75 nmol/L was 35.71%, which was significantly higher than that in serum 25-hydroxy vitamin D3 level≥75 nmol/L(21.88%, χ2=2.11, P=0.14). Conclusion The main risk factor for children with wheezing is viral infection, while the low level of serum 25-hydroxy vitamin D3 in children increases the risk of viral infection, resulting in increased risk of wheezing in patients,so the clinical can occur through the detection of serum 25- hydroxyvitamin D3 levels to predict and intervention for children with wheezing.

OBJECTIVETo re-evaluate the effects of different treatments to prevent from phlebitis induced by Chansu injection.

METHODPatients treated with Chansu injection were divided randomly into 4 groups with 50 per group, control group, the magnesium sulfate group, phentolaminum group, and anisodamine group. Patients in the control group only received the routine nursing treatment, and patients in the various experiment group received different interventions. The comparison was made in the morbidity and the starting time of occurrence of phlebitis, the severity of pain, duration of pain.

RESULTThe morbidity of phlebitis was 8%, 8%, 6% respectively. The starting time of phlebitis occurrence was (21 +/- 9.31) , (22.34 +/- 10.15), (20.19 +/- 11.23) h, respectively. The NRS of pain was (4. 15 +/- 1.03), (3.26 +/- 1.17), (4.32 +/- 1.36), respectively. The duration time of pain was (4.05 +/- 1.21), (3.37 +/- 1.17), (3.19 +/- 1.67) d, respectively. In control group, the morbidity of phlebitis, the starting time of occurrence of phlebitis, the severity of pain, duration of pain was 24%, (17 +/- 6.32) h, (6.58 +/- 1.29), (5.32 +/- 1.12) d, respectively. As compared with the control group, a significance difference was found between every group in three test groups and control group respectively (P<0.05).

CONCLUSIONThe morbidity and the starting time of occurrence of phlebitis, the severity of pain, duration of pain was significantly reduced respectively by external appication of magnesium sulfate, anisodamine, and intravenous drip infusion of phentolaminum.
