Objective:To explore a better virtual reality (VR) aviation rescue training mode and equipment platform by comparing the application of VR gloves and handle.Methods:A control study was used. Forty undergraduate students were enrolled by using cluster sampling method in this study. They were averagely divided into VR glove group and the VR handle group. Both groups were respectively trained with VR glove and VR handle based on an aviation rescue script of the craniocerebral trauma in traffic accident and the training effect was analyzed by comparing the assessments between VR training and reality simulation. The assessment were conducted both by VR and actual operation trainings and the content included operation, evaluation judgment, and total training time consumed. After the training was completed, the students of 2 groups were investigated by questionnaire.Results:In the VR assessment, the training time for the VR handle group [(26.94±2.00) min] was lower than that of the VR glove group [(31.23±2.23) min], and the difference was significant ( t=6.42, P<0.001). In the reality simulation assessment, the operation score of the VR glove group [(37.80±7.08) points] was higher than that of the VR handle group [(30.40±6.07) points], with a significant difference ( t=3.55, P<0.001). There was no significant difference between the scores of VR assessment and reality simulation assessment in the VR glove group. The reality simulation operation score of the VR handle group [(30.40±6.07) points] was lower than the VR operation score [(36.20±8.15) points], and the difference was significant ( t=2.55, P=0.015). The reality simulation operation time [(30.25±1.66) min] was higher than the VR operation time [(26.94±2.00) min], and the difference was significant ( t=5.59, P<0.001).The scores of assessing operation diversity and the integration with reality in VR glove group were higher than that in VR handle group ( Z=-4.00, -2.00, P<0.001,=0.045), but the scores of positioning accuracy and button functions were lower ( Z=-2.30, t=5.70, P=0.022,<0.001). Conclusions:VR technology has some advantages in helicopter aviation rescue training, has a broad prospect. As the VR human-machine data exchange equipment, both gloves and handles could bring good training effect even they have their own disadvantages. It is still necessary to improve VR software and equipment, and promote the quality of air rescue training in multiple aspects.

ObjectiveTo investigate the current status and influencing factors of hand hygiene practices among primary healthcare workers， and to provide a reference for improving hand hygiene behavior in primary healthcare institutions. MethodsA self-designed questionnaire was used to conduct a survey among medical staff of seven community health service centers in Jiading District， Shanghai， using a cluster random sampling method. The data collected were subjected to descriptive statistics， reliability and validity tests， correlation analysis， and structural equation model fitting. ResultsA statistical difference in hand hygiene compliance was found among medical staff with varying occupational types and educational levels （P<0.05）， and medical staff in clinical departments exhibited higher levels of hand hygiene compliance （P<0.05）. In the health belief model， among the core variables， healthcare workers’ perceived benefits， perceived barriers， and self-efficacy had a direct impact on hand hygiene behavior， with direct effect values of 0.341， -0.152， and 0.234， respectively. Meanwhile， cues to action and perceived severity of COVID-19 infection indirectly affected hand hygiene behavior， with an indirect effect value of 0.066 and 0.062， respectively. ConclusionHealthcare workers generally exhibit a high degree of hand hygiene compliance， but there are variations in hand hygiene scores among healthcare workers with different characteristics. Enhancing healthcare worders’ perception of benefits， action cues， and self-efficacy while reducing perceived barriers can effectively improve their hand hygiene behavior.

ResultsFrom 2013 to 2023, the overall proportion of medical visits for ILI cases in Jiading District was 2.70%. ILI cases were mainly distributed in the age group of ≥25 years, with a seasonal prevalence characteristic, mainly concentrated in the winter and spring, with an occasional small peak in the summer. A total of 12 423 specimens were tested for pathogenetic surveillance and monitoring, 3 651 of which were tested positive for nucleic acid detection, with a positive rate of 29.39%. The dominant strain was influenza A (H3N2) virus, accounting for 55.05%. There were statistical significant differences in the positive detection rates by different streets and townships(χ²=24.73，P<0.05）. The influenza network laboratory isolated and cultured influenza viruses from 3 154 nucleic acid‑positive samples sent by national influenza sentinel surveillance hospitals using 2 methodsMadin‑Darby canine kidney (MDCK) cells and specific pathogen free (SPF) chicken embryos, respectively, with a total isolation rate of 39.51%, and the isolation rate of MDCK cells (35.45%) was higher than that of SPF chicken embryos (5.36%). From 2013 to 2023, a total of 14 ILI outbreaks were reported in Jiading District, mainly in primary schools, kindergartens and secondary schools. ConclusionInfluenza in Jiading District, Shanghai, is mainly prevalent in the winter and spring, with different subtypes of influenza viruses alternating or co⁃circulating in different monitoring year. It is recommended to promote influenza vaccination, further improve influenza prevention and control measures, enhance health promotion to the age group of ≥25 years in winter and spring, and strengthen surveillance and monitoring on ILI outbreaks in collective units such as primary schools and childcare institutions, so as to reduce the disease burden.

Objective:To explore the mediating effect of professional self-efficacy between professional values and willingness to work on gerontological care of nursing students in higher vocational colleges.Methods:A total of 391 nursing students from Chengdu area full-time university were investigated by general information questionnaire, gerontological nursing career motivation questionnaire, professional values scale, and professional self-efficacy scale. Pearson correlation analysis and descriptive statistical analysis were performed by SPSS 21.0. Amos 26.0 was used to establish mediating effect model and verify the mediating effect.Results:The total score of 391 nursing students' willingness to work on gerontological care was (47.05±6.93), the willingness to work on gerontological care was positively correlated with professional self-efficacy and professional values ( r = 0.826, 0.775, respectively, all P<0.01), and professional self-efficacy played a partial mediating role between professional values and willingness to work on gerontological care, accounting for 64.82% of the total effect. Conclusions:The willingness to work on gerontological care of nursing students in higher vocational colleges is at a middle level. Professional values not only directly affect the willingness to work on gerontological care, but also indirectly take function through the professional self-efficacy. Professional self-efficacy plays a mediating role in professional values and willingness to work on gerontological care of nursing students in higher vocational colleges.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

ObjectiveTo investigate the prevalence of Staphylococcus aureus in a hospital in Jiading District， Shanghai， and to determine the enterotoxin gene profiles of Staphylococcus aureus isolated from patients and environment. MethodsSpecimens were collected from environment and patients from a hospital for Staphylococcus aureus isolation and identification. Furthermore， enterotoxin genes （SEA‒SEE） of Staphylococcus aureus were detected. ResultsA total of 54 Staphylococcus aureus strains were isolated from 780 hospital environmental specimens from 2018 to 2021， with a prevalence of 6.92%. In the armrests in the wards， patient’s pillows/quilts， and bedside cupboards， the prevalence was determined to be 20.00%， 20.00% and 16.67%， respectively. In contrast， in the computer’s mouse and keyboard and work clothes of physicians and nurses， the prevalence was 17.42% and 16.67%， respectively. Meanwhile， from 2018 to 2021， a total of 75 strains were collected from patients， of which 36.00%， 14.67% and 14.67% were from the departments of intensive care medicine （ICU）， neurosurgery and orthopedics， respectively. The prevalence of Staphylococcus aureus enterotoxin genes were 48.15% and 61.33% in the environment and patients， respectively. Furthermore， the prevalence of SEA， SEB， SEC， SED， and SEE genes were 14.67%， 41.33%， 9.33%， 1.33%， 1.33% in patients， respectively ， whereas 20.37%， 25.93%， 1.85 %， 1.85% and 0% in environmental specimens， respectively. In the environmental specimens isolated from comprehensive ICU， the prevalence of enterotoxin genes was 77.27%. In the patient's specimens， Staphylococcus aureus was mostly isolated in sputum. Additionally， the prevalence of enterotoxin genes was high in the patients of departments of respiratory medicine， ICU， and orthopedics. ConclusionPrevalence of Staphylococcus aureus remains moderate in the hospital environment. Enterotoxin genes of Staphylococcus aureus are common， with seb gene as the most common gene， followed by SEA gene. It warrants strengthening the disinfection and control of Staphylococcus aureus in the hospital， especially in the ICU.

Objective:To study the effect of Sanjie Xiaoliu Recipe on transplanted tumors in breast cancer mice through in vivo experiments, in order to explore the efficacy and mechanism of Sanjie Xiaoliu Recipe on breast cancer patients. Methods:45 BaL B/c female mice were selected to establish the transplanted tumor model of breast cancer. All the transplanted tumor models of breast cancer mice were randomly divided into five groups: the control group (intragastric administration of normal saline), the low, medium and high dose group of Sanjie Xiaoliu Recipe (intragastric administration of different doses of Sanjie Xiaoliu Decoction), and the paclitaxel group (intraperitoneal injection of paclitaxel). After 24 days of continuous administration, the diet and activities of mice were observed; the body weight, weight and volume changes of transplanted tumor mice were recorded, and the tumor inhibition rate was calculated. Western blot was used to detect the expression of epithelial mesenchymal transformation related proteins (E-cadherin, N-cadherin, Vimentin) in the transplanted tumor tissues of mice in each group.Results:(1) The food intake and activity status of mice treated with Sanjie Xiaoliu Recipe were less affected by the transplanted tumor of breast cancer. (2) The volume and weight of transplanted tumor in the treat groups were smaller than those in the control group (all P<0.01), and the volume of transplanted tumor in the middle dose group of Sanjie Xiaoliu Recipe was smaller than that in the low dose group ( P<0.05). The tumor inhibition rates among the treatment groups were: Sanjie Xiaoliu Recipe medium dose group 52.4%, paclitaxel group 40.3%, Sanjie Xiaoliu Recipe low dose group 39.5%, Sanjie Xiaoliu Recipe high dose group 34.1%. (3) The results of Western blot showed that the expression level of E-cadherin in the transplanted tumor tissue of the treat groups was higher than that in the control group, and the expression levels of N-cadherin and Vimentin were lower than that in the control group, with statistically significant difference (all P<0.05). Conclusions:The Sanjie Xiaoliu Recipe can improve the weakness and reduced consumption of breast cancer mice, which can inhibit the tumor mass growth in mice to a certain extent. Its mechanism may be that Sanjie Xiaoliu Recipe can inhibit the epithelial mesenchymal transformation of breast cancer and the invasion and metastasis of breast cancer.

Background: Postherpetic neuralgia (PHN) is the most common complication of acute herpes zoster. The treatment of PHN remains a challenge for clinical pain management. Despite the effectiveness of anticonvulsants, antidepressants, and lidocaine patches in reducing PHN, many patients still face intractable pain disorders.In this randomized controlled study, we evaluated whether hydromorphone through intravenous patient-controlled analgesia (IV PCA) was effective in relieving PHN. Methods: Patients with PHN were randomly divided into two groups, one group received oral pregabalin with IV normal saline, another group received oral pregabalin with additional IV PCA hydromorphone for two weeks. Efficacy was evaluated at 1, 4, and 12 weeks after the end of the treatments. Results: Two hundred and one patients were followed up for 12 weeks. After treatment, numerical rating scale (NRS) score of patients in the hydromorphone group was significantly lower than that of the control group, and the difference of NRS scores between the two groups was statistically significant at 4 and 12 weeks after treatment. The frequency of breakthrough pain in the hydromorphone group was significantly lower than that in the control group 1 and 4 weeks after treatment.After treatment, the quality of sleep in the hydromorphone group was significantly improved compared with the control group. The most common adverse reactions in the hydromorphone group were dizziness and nausea, with no significant respiratory depression. Conclusions IV PCA hydromorphone combined with oral pregabalin provides superior pain relief in patients with PHN, which is worthy of clinical application and promotion.
