Objective:To explore the application value of overall nursing intervention in PET/MR imaging in children with epilepsy.Methods:A total of 48 pediatric epilepsy patients who underwent PET/MR imaging in the Nuclear Medicine Department of the First Medical Center of the PLA General Hospital from July 2018 to October 2019 were enrolled. Among them, 24 patients with overall nursing intervention were used as the experimental group, and 24 patients were routine nursing intervention patients, who were served as the normal control group, and the examination time, Self-Rating Anxiety Scale (SAS) scores and patient satisfaction scores (filled in by the patient′s guardian) of the experimental group and the control group were collected and compared.Results:The inspection time of the experimental group was (15.1±0.5) min, significantly lower than (24.8±1.3) min of the control group ( tvalue was 32.940, P<0.01); the SAS score of the experimental group was (35.7±4.2) points, lower than(43.8±3.3) points of the control group ( tvalue was 7.357, P<0.01), and the patient satisfaction score was (92.8±5.5) points, higher than (69.8±11.1) points of the control group ( tvalue was 9.088, P<0.01 or 0.05). Conclusion:Overall nursing intervention in PET/MR imaging of pediatric patients with epilepsy can significantly cut down the examination time, reduce the anxiety of patients′ family members and improve the satisfaction of nursing care. It lays the foundation for clinicians to further accurately diagnose epilepsy foci and has important application value.

Objective To investigate the principal indicators of self-care ability in activities of daily living for the persons with physical disability. Methods Persons with physical disability were asked to select the top 3 items out of 27 items of activities of daily living in 3 levels. Results A total of 1960 questionnaires were send out, and 1862 were returned. For all the subjects, the items related with personal hygiene, such as toileting, self-cleaning and bathing, were selected 899 times (16.1%). The items related with personal health, as visiting community clinics and community exercising, were selected 570 times (10.2%). The items related with social interaction, as making a telephone and chatting, were selected 500 times (9.0%). For the persons with physical disability of first grade, the major items most selected were eating, entertaining, self-cleaning and transferring; and self-cleaning and housework for those of second grade; self-cleaning, community activities and housework for those of third grade; and community and interaction for those of fourth grade. Conclusion The persons with physical disability mostly focused on the activities related with personal hygiene, health and social interaction, and varied with the severity of disability, from self-cleaning to housework and social participation.

Objective:To explorer the optimal method of detecting donor kidney carrier carbapenem-resistant Klebsiella pneumoniae (CRKP).Methods:Clinical data were retrospectively analyzed for 1120 donation-after-circulatory-death (DCD) kidneys and bacterial detection of kidney perfusion fluid was performed from January 2015 to January 2019. A total of 1120 kidney perfusion fluid samples were collected with sterile tubes and submitted for culturing. And 451 specimens were delivered in sterile tubes and blood culture bottles simultaneously And 729 specimens assayed for carbapenemase genes with GeneXpert.Results:Among 1120 kidneys, CRKP was confirmed in 21 grafts with an infection rate of 1.87 %. The detection of carbapenemase genes with Genexpert showed that KPC was positive for 9/16 CRKP positive grafts. Sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 56.3 %, 100 %, 0, 43.7 % and 0.781 respectively. And 11 specimens delivered with sterile tube were culture positive for CRKP. Sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 52.3 %, 100 %, 0, 47.6 % and 0.762 respectively. Among 451 perfusion fluid samples collected with anaerobic blood culture bottle, 15 samples had a positive culture for CRKP. Sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 100 %, 100 %, 0, 0 and 1 respectively. In terms to anaerobic blood culture bottle, sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 60 %, 100 %, 0 , 40 % and 0.80 respectively.Conclusions:Genexpert assay is suitable for rapid and convenient detection of carbapenemase genes using kidney perfusion fluid. Culturing perfusion fluid samples collected with anaerobic blood culture bottle is clinically valuable diagnostic tool of CRKP. A combination of both methods is worthy of clinical promotion and application diagnosis of donor kidney derived CRKP in terms of greater accuracy and timeliness.

Objective:To evaluate the value of 18F-prostate specific membrane antigen (PSMA)-3Q PET/CT imaging in prostate cancer patients with serum prostate specific antigen (PSA) less than 1.00 μg/L after radical prostatectomy. Methods:From May 2021 to August 2022, 18F-PSMA-3Q PET/CT images and clinical data of 58 patients with prostate cancer (age 52-82 years) after radical prostatectomy with PSA less than 1.00 μg/L in Chinese PLA General Hospital were analyzed retrospectively. According to the level of PSA, patients were divided into three groups (0-0.19 μg/L group, 0.20-0.49 μg/L group, and 0.50-0.99 μg/L group). 18F-PSMA-3Q PET/CT images were analyzed according to the standardized evaluation criteria of molecular imaging, and lesions with the scores of molecular imaging PSMA (miPSMA)≥1 were defined as recurrent or metastatic lesions. The detection rates of 18F-PSMA-3Q PET/CT for patients in different PSA level groups were compared ( χ2 test). The PSA levels of patients with positive and negative scans were compared by using independent-sample t test. Results:Of the 58 patients, 36(62.1%, 36/58) patients and 85 lesions were found by 18F-PSMA-3Q PET/CT. There was 91.7%(33/36) with oligofocal lesions (1≤number of foci≤3) and 8.3%(3/36) with multiple lesions (number of foci>3). According to the location, 5.2%(3/58) of the recurrent lesions were found in the prostatic bed, 39.7%(23/58) in the bone lesions, 37.9%(22/58) in the pelvic lymph nodes, 12.0%(7/58) in the retroperitoneal lymph nodes and 5.2%(3/58) in the left clavicular lymph node metastases. There were 15 cases in 0-0.19 μg/L group, 22 cases in 0.20-0.49 μg/L group, and 21 cases in 0.50-0.99 μg/L group. The detection rates of 18F-PSMA-3Q PET/CT in the above groups were 5/15, 59.1%(13/22) and 85.7%(18/21), respectively ( χ2=10.33, P=0.006). There was significant difference in PSA level between patients with positive ( n=36) and negative ( n=22) 18F-PSMA-3Q PET/CT scans ((0.48±0.28) vs (0.28±0.25) μg/L; t=2.67, P=0.010). Conclusions:18F-PSMA-3Q PET/CT can be used to detect the recurrence or metastasis in prostate cancer patients with PSA level lower than 1.00 μg/L after radical prostatectomy. In this kind of patients, the common sites of lesions are bone, pelvic lymph nodes, retroperitoneal lymph nodes, left clavicular lymph nodes and prostatic bed, and oligofocal patients are more common.

Objective:To study the effect of the psychological counseling on the delivery mode of single birth elderly primiparas with anxiety and depression, and to seek a new and effective intervention way to improve the vaginal delivery rate.Methods:A preliminary screening was carried out for 486 single birth elderly primiparas received in the birth cohort research center of China Medical University from April 2018 to September 2019. Among them, 274 cases had mild, moderate or severe anxiety and depression. They were randomly divided into the observation group and the control group (n=137). The control group was given routine nursing measures and simple psychological education and the intervention group was given extra psychological counseling. Psychological counseling adopted the mode of combination of online and offline. The degree of anxiety and depression and the delivery mode were compared between two groups.Results:Before intervention, the degree of anxiety and depression between the observation group and the control group showed no significant difference. After intervention, the degree of anxiety and depression in the observation group was lighter than that of the control group ( χ2 value was 12.782, 6.647, P<0.05). The proportion of cesarean section, vaginal delivery, forceps delivery accounted for 32.1% (44/137), 67.2%(92/137), 0.7%(1/137) in the observation group, and 45.3% (62/137), 54.7%(75/137), 0 in the control group. The difference between the two groups showed statistical significance ( χ2 value was 5.787, P<0.05). Conclusion:The psychological counseling for the single birth elderly primiparas with anxiety and depression can effectively improve the psychological situation and increase the vaginal delivery rate.

Objective:To explore the correlation between post-transplant non-HLA antibodies and humoral rejection(HR)after kidney transplantation(KT).Methods:A retrospective study was conducted for KT recipients with non-HLA antibody level detected from September 2019 to January 2021.The recipients with biopsy confirmed HR and donor-specific HLA antibodies negative or feeble positive at the time of HR were designated as HR group while recipients with stable renal allograft function from 2 weeks post-KT to the time of detecting non-HLA antibody as stable group.The levels of HLA antibody, MHC classⅠchain-related gene A(MICA)antibody and 32 non-HLA antibodies were tested by Luminex single antigen bead and the levels of angiotensin Ⅱ type 1 receptor(AT1R)antibody quantified by enzyme-linked immunosorbent assay (ELISA). Inter-group differences in positive rate of non-HLA antibodies and number of positive non-HLA antibodies were analyzed.Results:Twenty-four recipients had positive non-HLA antibodies while the remainders had no positive non-HLA antibodies.Three HR recipients were positive for actin antibody, collagen Ⅲ antibody, glutathione S-transferase theta-1 antibody or IFN-γ antibody respectively.However, all four non-HLA antibodies of stable recipients were negative.There was significant inter-group difference( P=0.017). Four HR recipients were positive for collagenⅡantibody while only 1 stable recipient was positive for collagenⅡantibody.The positive rate of collagenⅡ antibody was significantly higher in HR recipients than that in stable recipients( P=0.023). HR recipients had an average of 2.36 positive non-HLA antibodies while stable recipients had an average of 0.90.There was significant inter-group difference ( P=0.008). Conclusions:A high level of non-HLA antibodies may elevate the risk of HR after KT.

Objective:To explore the protective effects of exosomes derived from bone marrow mesenchymal stem cells(BMSC)on ischemia-reperfusion injury(IRI)in mice.Methods:A total of 30 C57BL/6 mice were randomly grouped into 6 groups of control, Norm-BMSC-exo, Hypo-BMSC-exo, IRI, Norm-BMSC-exo+ IRI and Hypo-BMSC-exo+ IRI.The model for IRI(25 min)was constructed.The serum levels of creatinine(Cr)and blood urea nitrogen(BUN)and histomorphology were examined at 24 h post-reperfusion.The levels of tumor necrosis factor-alpha (TNF-α), interleukin-1β(IL-1β)monocyte chemoattractant protein-1(MCP-1)and interleukin-10 (IL-10)were measured.The survival rate was observed for 7 days post-IRI.We also detected macrophage polarization glycolysis and oxidative phosphorylation(OXPHOS).Results:Compared with IRI group, Norm-BMSC-exo+ IRI group showed low levels of creatinine(Cr)and blood urea nitrogen(BUN)and mild pathological injury.The protective effects were enhanced in Hypo-BMSC-exo+ IRI group.BMSC-exo pretreatment could significantly improve the survival rate of mice post-IRI.Reverse transcription-polymerase chain reaction(RT-PCR)revealed that BMSC-exo significantly lowered the levels of TNF-α, IL-1β, MCP-1 and elevated the level of IL-10.BMSC exosomes polarized macrophage toward an M2 phenotype.And Hypo-exo could reprogramme macrophages to undergo a metabolic switch toward OXPHOS and away from glycolysis.Conclusions:Hypo-BMSC-exo could improve kidney injury via inducing M2 polarization in macrophages through promoting OXPHOS and suppressing glycolysis.

Objective To explore the rapid diagnosis and clinic treatment of donor-derived carbapenem-resistant Klebsiella pneumoniae (CRKP) infection in renal transplant recipients .Methods Retrospective analysis was performed for clinical data and the diagnosis and treatment of 9 renal transplant recipients with donor-derived CRKP infection from March 2017 to May 2019 .Results Among 526 renal transplant recipients ,nine were diagnosed with donor-derived CRKP infection by bacterial culture or KPC enzyme gene test .The infection rate was 1 .71％ .One recipient receiving carbapenem and tigecycline died while the remainders survived after a treatment of ceftazidime-avibactam and carbapenem . One recipient underwent graft resection . Among 8 recipients on ceftazidime-avibactam ,5 cases received a standard dose of 3 .75 g/d while another 3 cases had a high dose of 7 .5 g/d .One patient in standard-dose group underwent graft resection due to an arteriorrhexis of artery anastomosis .After graft resection ,the patient received a high dose of ceftazidime-avibactam and survived to date .The grafts of three patients in high-dose treatment group survived .Conclusions KPC enzyme gene detection plus injecting lavage fluid into blood culture bottle for bacterial culture is rapid and accurate for diagnosing donor-derived CRKP infection . A combination of ceftazidime-avibactam plus carbapenem is effective for donor-derived CRKP infection .A high dose of ceftazidime-avibactam may improve the efficacy without obvious side effects .

Major depressive disorder (MDD) is characterized by emotion dysregulation. Whether implicit emotion regulation can compensate for this deficit remains unknown. In this study, we recruited 159 subjects who were healthy controls, had subclinical depression, or had MDD, and examined them under baseline, implicit, and explicit reappraisal conditions. Explicit reappraisal led to the most negative feelings and the largest parietal late positive potential (parietal LPP, an index of emotion intensity) in the MDD group compared to the other two groups; the group difference was absent under the other two conditions. MDD patients showed larger regulatory effects in the LPP during implicit than explicit reappraisal, whereas healthy controls showed a reversed pattern. Furthermore, the frontal P3, an index of voluntary cognitive control, showed larger amplitudes in explicit reappraisal compared to baseline in the healthy and subclinical groups, but not in the MDD group, while implicit reappraisal did not increase P3 across groups. These findings suggest that implicit reappraisal is beneficial for clinical depression.
