ObjectiveTo develop an emotion management course and evaluate its effectiveness in improving emotion regulation, coping strategies, and anxiety and depression among first-year university students, so as to provide a basis for colleges to optimize mental health education courses. MethodsUsing a multi-stage cluster random sampling method, five classes of first-year students (n=169) from a university were randomly selected as participants, with three classes assigned to the experimental group (n=102) and two classes to the control group (n=67). The experimental group attended both the standard mental health education course and the emotion management course developed in this study, while the control group only attended the standard mental health education course. Pre- and post-intervention assessments were conducted using the Emotion Regulation Questionnaire (ERQ), Simplified Coping Style Questionnaire (SCSQ), Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS). ResultsBefore the intervention, there were no significant differences between the experimental group and the control group in ERQ, SCSQ, SDS, and SAS scores (P>0.05). After the intervention, the experimental group demonstrated greater improvements than the control group in the ERQ expression inhibition subscale (14.42±5.05, 16.12±5.65), SCSQ positive coping tendency (1.97±0.51, 1.80±0.49) and negative coping tendency (1.26±0.55, 1.47±0.50), as well as in SDS (50.26±11.48, 53.86±8.21) and SAS (43.96±11.97, 47.59±9.50) scores (t value: 2.039, 2.144, 2.572; Z value: -2.214, -2.486; P<0.05). Compared with pre-intervention scores, the experimental group also showed improvements in the ERQ cognitive reappraisal subscale (32.19±5.76, 30.92±6.18), SCSQ positive coping tendency (1.97±0.51, 1.83±0.48), and SDS scores (50.26±11.48, 50.75±11.59) (t value: -2.654, -3.027; Z value: -2.100, P<0.05). ConclusionThe emotion management course effectively enhances students’ use of cognitive reappraisal strategies while reducing reliance on expressive suppression. It also contributes to improvements in coping strategies for life events and alleviates symptoms of depression and anxiety. Universities should consider integrating emotion management education into their curricula to enhance the mental well-being of first-year students.

Objective To retrospectively analyze the efficacy and safety of low-dose antithymocyte globulin(ATG)combined with low-dose post transplantation cyclophosphamide(PTCY)in prevention of graft versus host disease(GVHD)after haploidentical transplantation.Methods Clinical data of 90 patients receiving haplotype matched transplantation in No.920 Hospital of PLA Joint Logistic Support Force from January 2022 to February 2023 were collected,and they were divided into study group(n=47)and control group(n=43)according to different GVHD prevention programs.The patients of the study group were given low-dose ATG combined with low-dose PTCY,and those of the control group received standard dose of PTCY.The implantation status,occurrence of GVHD,survival status and other indicators were analyzed between the 2 groups.Results ① Both groups of patients were successfully implanted,the median duration for neutrophil implantation(11 vs 17 d,P＜0.05)and platelet implantation(12 vs 20 d,P＜0.05)was significantly shorter in the study group than the control group.The incidence of grade Ⅱ～Ⅳ aGVHD(12.8％vs 34.9％,P＜0.05)and grade Ⅲ～Ⅳ aGVHD(6.4％ vs 20.9％,P＜0.05)was significantly lower in the study group than the control group,so was the non-recurrent mortality rate(6.4％vs 20.9％,P＜0.05)and the incidence of hemorrhagic cystitis(12.8％ vs 34.9％,P＜0.05).② By the end of the study,there were no significant differences in the incidence of mild and moderate and severe cGVHD,recurrence rate,reactivation rates of EBV and CMV,overall survival rate or progression-free survival rate between the 2 groups.Conclusion For haploidentical transplantation,low-dose ATG combined with low-dose PTCY has the advantages of lower incidence of GVHD,non-recurrent mortality,incidence of hemorrhagic cystitis and faster implantation.

Objective To preliminarily explore the efficacy of chimeric antigen receptor T cells(CAR-T)targeting CD 123 in the treatment of acute myeloid leukemia(AML)and the role of dasatinib in the treatment of CD123 targeting CAR-T induced side effects.Methods Clinical data of 1 patient with relapsed AML admitted to No.920 Hospital of PLA Joint Logistic Support Force in September,2019 were collected.The patient relapsed after previous multi-line chemotherapy and was treated with CD123 targeting CAR-T therapy.The routine blood changes of the patient after treatment were observed.Dasatinib was used when agranulocytosis occurred,40 mg orally 3 times per day,and was stopped when agranulocytosis was relieved.Changes in blood cells,CAR-T amplification,and disease control were observed.The patient was followed up for over 1 year.Results Flow cytometry for bone marrow showed that minimal residual disease negative result was observed in 30 d after infusion.The patient remained disease-free for over 1 year.After CD 123 CAR-T cells infusion,significant expansion of CAR-T cells was observed,accompanied by granulocyte deficiency and cytokine release syndrome(CRS).After using dasatinib,inhibition of CAR-T cell expansion was observed,accompanied by blood cell recovery,and CRS symptoms were alleviated.After stop of dasatinib,CAR-T cells expanded again and blood cells decreased again.Conclusion CAR-T cells targeting CD 123 have certain efficacy in the treatment for relapsed AML.Dashatinib has a blocking effect on the amplification and function of CAR-T,which can alleviate bone marrow suppression caused by CD 123 targeting CAR-T and avoid severe CRS.

Virus is one of the common causes of respiratory tract infection in children.Viral infection involves the action of multiple immune cells and inflammatory mediators，understanding the immune mechanism of virus-host interaction during respiratory infection may be helpful for etiological diagnosis of viral infections.As the main immune cells of the lungs，alveolar macrophages on the mucosal surface of the respiratory tract play an important role in maintaining pulmonary immune homeostasis（immune monitoring，initiation and regulation of inflammatory response，killing pathogens）due to their unique position.This article will briefly review the immune regulation mechanism of alveolar macrophages in the occurrence and development of respiratory tract viral infection in children，in order to provide reference for the prevention and treatment of viral infection.

Objective:To analyze the status quo of type D personality, intolerance of uncertainty and family support in first-episode stroke patients, and to explore the mediating role of family support between type D personality and intolerance of uncertainty in first-episode stroke patients, in order to provide reference for formulating relevant clinical intervention measures to promote the physical and mental health of first-episode stroke patients.Methods:This study was a cross-sectional investigation. A total of 300 patients with acute first-episode stroke who met the inclusion and exclusion criteria in the Department of Neurology of the General Hospital of Ningxia Medical University and the First People′s Hospital of Yinchuan from May 2023 to September 2023 were selected as the study objects by convenience sampling method. The general data questionnaire, Type D personality Scale-14, Family Caring Index Scale and the Intolerance of Uncertainty Scale were used to investigate them. Pearson correlation analysis was used to test the correlation between variables, and SPSS plug-in PROCESS 3.5 was used to test the mediation effect.Results:Finally, 300 questionnaires were effectively collected, including 228 males and 72 females. Patients aged ≥ 60 years old were the majority, accounting for 49.3% (148/300). The detection rate of type D personality in the first stroke patients was 37.3% (112/300), and the total score of Type D personality inventory, family support and intolerance of uncertainty of type D personality in the first stroke patients were (22.16 ± 9.95), (6.40 ± 2.23), (27.82 ± 7.93) points. The correlation analysis results showed that the intolerance of uncertainty of type D personality in the first stroke patients was positively correlated with type D personality scores ( r=0.675, P<0.001). There was a negative correlation with family support score ( r=-0.644, P<0.001). The results of mediating effect analysis showed that family support played a partial mediating role in the relationship between type D personality and intolerability of uncertainty in first-stroke patients, and the mediating effect accounted for 34.94% of the total effect. Conclusions:The mediating role of family support between type D personality and intolerability of uncertainty in first-stroke patients is established. In the future, the level of family support of patients can be continuously improved to reduce their intolerability of uncertainty, so as to promote the physical and mental health of patients and improve their quality of life.

Objective To investigate the survival time of patients diagnosed with sporadic Creutzfeldt-Jakob disease in China between 2020 and 2022 and explore the associated factors influencing survival.Methods A retrospective analysis was conducted on clinically diagnosed cases with complete information on sporadic Creutzfeldt-Jakob dis-ease diagnosed by the China Creutzfeldt-Jakob disease surveillance network from 2020 to 2022,baseline information of patients was obtained from the case files,telephone follow-up was used to obtain the treatment and survival status of the patients after the diagnosis,life-table method was used for estimating the survival rate,Kaplan-Meier method was used for calculating the median survival time and the 95％CI,Cox regression model was used for univariate and multivariate analyses were used to screen for factors influencing survival time.Results The median survival time of the 300 patients was 5 months(95％CI:4.165-5.835).Univariate analysis revealed that factors such as age at onset,regional distribution,presence of corticobasal or extrapyramidal symptoms as initial manifestations,number of initial symptoms,presence of corticobasal or extrapyramidal functional abnormalities,number of major clinical manifestations,presence of typical electroencephalogram findings,and use of nasal feeding during the course of the disease were potential factors influencing survival time(P＜0.1).Multivariate analysis showed that the risk of death in patients with onset age＞65 years was 1.350 times higher than in patients with onset age ≤65 years(P=0.021,95.0％CI:1.046-1.742).Patients without pyramidal or extrapyramidal dysfunction had a 0.674-fold lower risk of death compared to those with these symptoms(P=0.020,95.0％CI:0.483-0.939).Patients who did not receive nasal feeding had a 1.817-fold higher risk of death compared to those who did(P＜0.001,95.0％CI:1.406-2.349).Conclusion Age at onset,the presence of pyramidal or extrapyramidal functional abnormalities,and the use of nasal feeding during the disease course are factors influencing the survival time of pa-tients clinically diagnosed with sCJD.

Objective:To understand the medical care of patients with sporadic Creutzfeldt-Jakob disease in China and its relationship with survival time.Methods:A retrospective analysis was performed on data of 150 patients with sporadic Creutzfeldt-Jakob disease diagnosed by China′s Creutzfeldt-Jakob Disease Surveillance Network during the period of January 1, 2021 to December 31, 2022 in this study, and telephone follow-up with family members was used to obtain information of the patients′ care, treatment, and survival after diagnosis. Survival was estimated by life table method, median survival time and 95% confidence interval ( CI) were calculated by Kaplan-Meier method, log-rank method was used to compare the difference in survival time between different groups, and multifactorial analysis was performed by COX proportional risk regression model regarding the influencing factors on patients′ survival time. Results:The median survival time of 150 patients with sporadic Creutzfeldt-Jakob disease was 6 months, and the cumulative lifetime survival rates at 2, 6, 12, and 18 months were 62%, 39%, 22%, and 9%, respectively. The result of univariate analysis showed that the differences in survival time between groups with the presence or absence of cortical blindness in the first symptom, the presence or absence of respiratory support (oxygen therapy), the presence or absence of adjunctive medication, and the presence or absence of tube feeding (nasogastric) were meaningful ( P<0.1). Multifactorial COX regression analysis showed that the risk of death in patients without adjuvant medication was 1.429 times higher than that in patients with adjuvant medication (95.0% CI: 1.014-2.014), and the risk of death in patients without tube feeding (nasal feeding) was 1.479 times higher than that in patients with tube feeding (nasal feeding) (95% CI: 1.052-2.081). Conclusions:Whether or not adjuvant medication is administered and whether or not tube feeding (nasogastric) is used are factors that affect survival time in patients with sporadic Creutzfeldt-Jakob disease, and the administration of appropriate adjuvant medication and tube feeding (nasogastric) may contribute to prolonging survival time in patients with sporadic Creutzfeldt-Jakob disease.

Objective:To explore the application effect of breakthrough series (BTS) quality improvement model in the prevention of catheter-related bloodstream infection in hospitalized patients with indwelling non-cuffed catheter (NCC).Methods:Using a non synchronous pre and post control study method, convenience sampling was used to select NCC patients from four hospitals in Tianjin from January to September 2022 who received conventional nursing plans as the control group, and NCC patients from February to October 2023 who received nursing plans based on the BTS quality improvement model as the observation group. Compared the incidence of NCC related bloodstream infections between two groups of patients, the implementation of key preventive measures for NCC related bloodstream infections by nursing staff, and patient satisfaction.Results:Among the 984 patients included in the control group, there were 687 males and 297 females, aged (62.43 ± 13.77) years old; among the 959 patients included in the observation group, there were 651 males and 308 females, aged (61.96 ± 13.89) years old. After applying the improved model, the incidence of NCC related bloodstream infections in the observation group was 0.12‰ (1/8 676), lower than the control group′s 0.71‰ (7/9 827), and the difference was statistically significant ( χ 2=4.37, P<0.05) ;the implementation rate of key measures for preventing NCC related bloodstream infections in the observation group was 90.00% (54/60) for catheter outlet care and 91.67% (55/60) for maximizing sterile barrier, both higher than 70.37% (38/54) and 75.93% (41/54) in the control group, with statistical significance ( χ2=7.03, 5.30, both P<0.05); the total satisfaction rate of patients in the observation group was 92.91% (891/959), which was higher than 58.64% (577/984) in the control group, and the difference was statistically significant ( χ2=15.28, P<0.05). Conclusions:The implementation of BTS quality improvement model is helpful to improve the nursing quality of patients with indwelling NCC dialysis and improve the patient outcomes.
