Objective To understand the distribution and change in drug resistance of common pathogens before and after the implementation of special rectification activity on antimicrobial use in 2011-2015,and provide guidance for clinical application of antimicrobial agents.Methods Antimicrobial use in hospitalized patients and pathogens isolated from patients in a hospital from 2011 to 2015 were collected,changing trend of resistance rates of major pathogens to commonly used antimicrobial agents was analyzed.Results From 2011 to 2015,antimicrobial utilization rate in hospitalized patients dropped from 75.84%to 37.35%,antimicrobial use density decreased from 59.53 per 100 patient days to 33.63 per 100 patient days,both showed a downward trend(both P<0.05).A total of 10 091 strains of pathogens were isolated,2 338(23.17%)of which were gram-positive bacteria,7 110(70.46%)were gram-negative bacteria,and 643(6.37%)were fungi.The top five pathogens were Escherichia coli(20.85%),Klebsiella pneumoniae(15.90%),Pseudomonas aeruginosa(11.70%),Staphylococcus aureus(7.35%),and Acinetobacter baumannii(6.82%).Resistance rates of major pathogens to commonly used antimicrobial agents decreased year by year(P<0.05),resistance rates of Escherichia coli and Klebsiella pneumoniae to piperacillin/tazobactam,cefoxitin,and amikacin declined most obviously(all<4%in 2015);compared with Acinetobacter baumannii,Pseudomonas aeruginosa had higher sensitivity to commonly used antimicrobial agents,resistance rates to piperacillin/tazobactam,cefoperazone/sulbactam,ceftazidime,cefepime,amikacin,and ciprofloxacin decreased obviously,resistance rate to above antimicrobial agents was <20%,to carbapenems was higher than other commonly used antimicrobial agents.Resistance rates of Acinetobacter baumannii to amikacin,levofloxacin decreased most obviously,to meropenem and imipenem increased obviously,in 2015 were both above 50%.Resistance rate of Staphylococcus aureus to fluoroquinolones declined most obviously(<2%),vancomycin-resistant strains were not found.Conclusion After the implementation of special rectification activity,resistance rates of common pathogens decreased with the decline of antimicrobial use,rational use of antimicrobial agents may be related to delaying bacterial resistance.

Objective: To investigate the feasibility and efficiency of three-line relaxation-based group intervention on mental stress management among nursing students. Methods: A total of 224 nursing students were randomly divided into the intervention group in which three-line relaxation training for 12 weeks were delivered together with psychological health education (PHE), and the control group which only delivered PHE. The SelfRating Anxiety Scale (SAS) and the Self Rating Depression Scale (SDS) were used before and after intervention. T-test was used to compare inter-group difference. Results: After 4-week intervention, there’s no significant difference in the score of SAS and SDS between the two groups(P>0.05). After 12-week intervention, average SAS and SDS score of intervention group was significantly decreased compared with before intervention (both P<0.01). After 12-week intervention, no significant changes were observed in the score of SAS and SDS in the control group (both P>0.05). After 4-and 12-week intervention, average score in SAS and SDS of intervention group was significantly lower than that of the control group(P<0.05). Conclusion Three-line relaxation is effective in relieving mental stress of nursing students.

Objective:To explore the project characteristics and correlation of community nursing service demand in the elderly people, so as to provide a reference for improving community nursing service.Methods:Quantitative study: a retrospective survey was adopted to collect the relevant information of 206 elderly people who participated in various nursing service projects in Saltu District Street Health Service Center of Daqing from November to December 2021, including the content and frequency of participating nursing service projects and the total number of participating. Qualitative study: 15 elderly people were selected for interviews by the stratified sampling method, based on the principle of data saturation. The Apriori association analysis method was used to analyze the association of different nursing service items, and calculate support degree, confidence degree and promotion degree of item/item set.Results:The total number of the elderly people participating in community nursing services was 104, including health consultation, health lectures, blood pressure measurement, blood glucose measurement, intravenous infusion, fun activities 6 categories, with support degree of the item/itemset>0.02, confidence degree>0.45, lift degree>1, and there was a mutual promotion effect among the projects. A total of 3 themes were summarized in the qualitative research: the needs and participation of the elderly people in community nursing service projects, the influencing factors of the elderly people's participation in community nursing service projects, and health promotion effect of community nursing service projects in the elderly people.Conclusions:The elderly have different demand for community nursing service, and there is a mutual promotion effect among the projects. Community medical staff should set up reasonable service items according to the characteristics of project correlation, improve the level of community nursing service, and guarantee the basic health of the elderly people.

Objective To examine the effect of a Caregiving Self-Management Support (C-SMS) Program on self-efficacy, social support for family caregivers of people with dementia and psychological symptom of patients. Methods Using the convenient sampling method, 41 caregivers of dementia patients were selected as the study objects from September 2016 to September 2017 in the Memory Disorders Outpatient Department of two ClassⅢ Grade A hospitals in Shanghai. They were divided into the experimental group(n=26) and control group(n=15) according to their willingness. Totally 4 participants in each of the two groups dropped out of the study in the middle. In the experimental group, a total of 6 times, once in 2 weeks social support group activities were carried out; in the control group, a total of 3 telephone instruction, once a month was carried out, all participants were distributed with the Caregiver Educational Booklet prepared by the research team and participated 3 education seminars during the follow-up visit. Self-Efficacy Questionnaire for Chinese Family Caregivers(SEQCFC) and Medical Outcome Study Social Support Survey(MOS-SSS) and Revised Memory and Behaviour Problems Checklist(RMBPC) were used to compare the effect of intervention. Results The time effect of the total score of SEQCFC was significant (P＜ 0.01). There was a statistically significance in the interaction on social support score between groups and time (P＜ 0.05). After intervention and follow-up, the self-efficacy scores of family caregivers in the experimental group were higher than the baseline (P＜0.05). There were significant time effect in the total score of behavioral and psychological symptom behavioral symptoms, memory and depression related problems (P＜0.05). The total score of behavioral and psychological symptom, score of the disruptive behaviour dimension after follow-up visit, scores of the depression dimension after intervention and follow-up visit in the experimental group were all lower than the baseline (P＜ 0.05). Conclusions The self-management support project of caregivers can improve the self-efficacy of family caregivers and alleviate the behavioral and psychological symptom of dementia patients.

Objective: To investigate the prevalence of somatization symptoms and its correlation with social support in patients with depressive disorder. Methods: Two hundred and fourteen hospitalized patients with depressive disorder were recruited. Patients were evaluated with Somatic Symptom Inventory (SSI), Perceived Social Support from Family Scale (PSS-Fa), Social Support Rating Scale (SSRS) and the general questionnaire. Results: The average SSI scores of depressive patients was 49.63±15.53, with 26.2% (56/214) of the patients having moderate to severe level of somatic symptoms. The most common moderate to severe somatic symptoms in depressive patients were "feeling fatigued (61.3%, 131/214), weak (49.5%, 106/214), not feeling well (47.7%, 102/214), feeling faint or dizzy (48.6%, 104/214), or constipation (29.9%, 64/214)" . The average SSRS scores of patients was low (33.24±7.16). The SSI scores and its non-painful dimension (39.05±12.14) were significantly negatively correlated with family support (11.03±3.45) (r=-0.150, P=0.03; r=-0.153, P=0.02) .The SSI scores, and its somatization dimension scores (49.63±15.53) and painful dimension scores (10.58±4.18) were negatively correlated with the total scores of social support (33.24±7.16) (r=-0.164, P=0.02; r=-0.183, P=0.01; r=-0.136, P<0.05) and subjective support (19.14±4.81) (r=-0.167, P=0.02; r=-0.163, P=0.02; r=-0.177, P=0.01) . The SSI scores and its non-painful dimension of patients were negatively correlated with support utilization (r=-0.179, P=0.01; r=-0.194, P=0.01) . Conclusion Somatic symptoms are prevalent and severe in patients with depressive disorder. The somatic symptoms of depressive patients was closely correlated with decreased social support, especially low subjective support and support utilization.

[Objective] To explore the clinical significance of the IgG1 and IgG3 subtypes of red blood cell unexpected antibodies. [Methods] The IgG1 and IgG3 typing tests were performed on the IgG type alloantibodies of Rh, Duffy and Kidd blood group systems detected in our hospital. Additionally, IgG1 and IgG3 titers were measured and monocyte monolayer assay was performed on 12 cases of anti-E to analyze the characteristics of different IgG subtypes of anti-E. [Results] Among the 115 cases of unexpected IgG antibodies, 81 cases of monospecific antibodies were predominantly IgG1 (58.02%, 47/81); 17 cases of mixed antibodies were predominantly IgG1+IgG3 (47.06%, 16/34). In monocyte monolayer assays, the phagocytic rate and antibody titer of IgG1 and IgG3 antibodies were positively correlated, while in IgG1+IgG3 complex antibodies, it was mainly associated with IgG3, with higher antibody titers correlating with higher phagocytic rates. When the anti-E titers were 32 for all, the IgG1+IgG3 complex had the highest phagocytosis rate, followed by IgG3 alone, and IgG1 alone had the lowest phagocytic rate. [Conclusion] Monospecific antibodies among unexpected antibodies are primarily IgG1, while mixed antibodies are mainly IgG1+IgG3. The results of MMA indicate that the immune response caused by the IgG1+IgG3 complex is more severe. Therefore, when antibodies like anti-E coexist with other antibodies, even if the titer is low, the immune response may still be severe, which should be taken seriously in clinical practice.
