Objective:To investigate the pathological change mechanism of patients with chronic active Epstein-Barr virus infection (CAEBV).Methods:The clinical manifestations, laboratory examinations, diagnosis and treatment of one CAEBV patient in Suzhou Hongci Hematology Hospital of Jiangsu Province were retrospectively analyzed with review of related literature.Results:Combined with the results of laboratory, lymph node biopsy and bone marrow tests in different periods, the patient initially showed lymphoproliferative disease, and gradually transformed into lymphoma with the diagnosis results of EB virus-related lymphocyte clones in different periods. The patient received the corresponding treatment plan in different periods, but eventually died due to hemophagocytic syndrome and rapid progress of the disease.Conclusion:CAEBV may cause lymphocytes to gradually evolve from polyclonal to monoclonal state.

Objective To explore the effect of brain-derived neurotrophic factor (BDNF) Val66Met polymorphism,environmental factor and their interactions on antidepressant treatment.Methods 340 patients of major depressive disorder (MDD) who met the diagnosis criteria of MDD ( DSM-Ⅳ Axis Ⅰ) were recruited.280 patients of them were finished 12 weeks antidepressant treatment.The severity of depression was measured with the Hamilton Depression Rating Scale (HDRS) before and after 12 weeks antidepressant treatment.Childhood Trauma Questionnaire,28-item Short Form (CTQ-SF) and Life Events Scale (LES) were used to evaluate childhood adverse and life stress before onset.Genotyping of BDNF Val66Met polymorphism was detected by Illumina GoldenGate assays.Results Male patients proportion were significantly higher in non-remitters than remitters (P =0.008 ).After adjusting by gender, the frequencies of genotype and allele for the BDNF Val66Met polymorphism were no significant difference between remitters (AA: AG: GG = 28: 79: 40, A:G = 135:159 ) and non-remitters (AA: AG: GG = 29:81:23 ,A: G = 139:127 ) (P ＞0.05 ).There was no significant difference of CTQ scores and LES scores between the two groups (P＞0.05 ).The regression analysis showed that social intercourse problem and age were the risk factor for the severity of depression.The gender, HDRS baseline scores and mental disorder family history were associated with the efficacy of 12 weeks antidepressant.However,there was no significantly relationship between the interaction of BDNF Val66Met polymorphism and environment with the antidepressant treatment.Conclusion The older men with the mental disorder family history, severe depression symptom would be less-response to antidepressant treatment.However, BDNF Val66Met polymorphism, childhood trauma, life events stress and the interaction of BDNF Val66Met polymorphism and environment have no significantly effect on the 12 weeks antidepressant treatment.

Objective:To explore the status quo and influencing factors of anxiety among caregivers of children with cancer during chemotherapy to provide a reference for clinical intervention.Methods:In this cross-sectional study, 133 caregivers of children with cancer during chemotherapy admitted at the First Affiliated Hospital of Zhengzhou University between May and August 2020 were selected by convenient sampling and investigated with the General Information Questionnaire, Generalized Anxiety Disorder-7 (GAD-7) , and Chinese version of Cognitive Fusion Questionnaire (CFQ) . In this study, a total of 133 questionnaires were distributed and 124 valid ones were returned, accounting for an effective response rate of 93.2%.Results:The GAD-7 score of the 124 caregivers was 10.50 (6.00, 15.75) ; the incidence of anxiety was 84.68% (105/124) ; and the Chinese version of CFQ score was 42.00 (32.00, 50.00) . There was a positive correlation between the GAD-7 and CFQ scores ( r=0.639, P<0.01) . Binary logistic regression analysis showed that cognitive fusion was a risk factor for anxiety among caregivers of children with cancer during chemotherapy ( P<0.01) . Conclusions:The anxiety and cognitive fusion levels among caregivers of children with cancer during chemotherapy are relatively high and positively correlated with each other. Targeted interventions should be provided in clinical practice for the cognitive fusion of caregivers of children with cancer during chemotherapy to reduce their anxiety and improve the quality of care for children.

Objective:To investigate the effect of sequential suture and adhesion on craniomaxillofacial skin contusion and laceration.Methods:A total of 189 patients with craniomaxillofacial skin contusion and laceration (CMFSCL) were randomly divided into three groups: 66 cases in SSA group, 63 cases in CS group and 60 cases in TS group. Operation time, visual analogue scale (VAS), Vancouver scar scale (VSS) and adverse reactions incidence were compared and analyzed between the three groups. Effect and satisfactory scale were evaluated.Results:Operation time in SSA group (10.67±1.26) min was significantly less than that in CS (18.91±1.38) min and TS group (17.96±1.43) min ( P<0.05). VAS in SSA group 24 h post-operation (3.11±1.01) was significantly lower than that in CS and TS group ( P<0.05). VSS in SSA group 6 months post-operation (1.18±0.21) was significantly lower than that in CS (3.78±1.01) ( P<0.05) and TS group (5.98±1.06) ( P<0.01). Total effective rate of SSA group (96.5%) was significantly higher than that in CS (85.7%) ( P<0.05) and TS group (56.1%) ( P<0.01); total effective rate in CS group was significantly higher than that in TS group ( P<0.05). Infection and dehiscence rates in SSA group were lower than those in CS and TS group ( P<0.01). Satisfactory rate of SSA group (99%) was significantly higher than that of CS (89.1%) and TS group (71.3%) ( P<0.05); the satisfactory rate of CS group was significantly higher than that of TS group ( P<0.05). Conclusions:Sequential suture and adhesion technique is simple and effective for craniomaxillofacial skin contusion and laceration, which is worthy of clinical promotion.

Objective:To investigate the effect of ubiquitin binding enzyme 2T (UBE2T) on the radiosensitivity of lung adenocarcinoma and unravel its possible mechanism.Methods:A total of 45 patients pathologically diagnosed with different stages of lung adenocarcinoma and treated with radiotherapy in the Second Affiliated Hospital of Zunyi Medical University from March, 2019 to December, 2021 were enrolled, and the efficacy was evaluated according to response evaluation criteria in solid tumors (RECIST1.1). All patients were divided into radiosensitive group ( n=25) and radioresistant group ( n=20). Radiosensitive group was complete remission (CR)+partial remission (PR), and radioresistant group was stable disease (SD) + progression disease (PD). Immunohistochemistry (IHC) was used to calculate the score based on the staining intensity and the number of positive cells. Chi-square test was combined to analyze the correlation between the expression level of UBE2T in paraffin specimens of lung adenocarcinoma patients and the radiosensitivity of patients. Lentivirus UBE2T-interfered (UBE2Tsh) A549 and UBE2T-overexpressed SPC-A-1 lung adenocarcinoma cells and their respective controls were constructed for irradiation and colony formation assay. The survivor fraction curve was fitted by single-hit multi-target model. The DNA double-strand break (DSB) marker γH2AX foci were detected by immunofluorescence (IF). The expression levels of UBE2T, γH 2AX and Rad51 proteins were detected by Western blot. Cell cycle and apoptosis rate of A549 were determined by flow cytometry. Binary variables were statistically analyzed by Fisher's exact probability method and measurement data were assessed by t-test. Results:High-expression level of UBE2T was correlated with the radiosensitivity of lung adenocarcinoma patients ( P<0.05). UBE2Tsh improved the radiosensitivity of A549 lung adenocarcinoma cells, and the sensitizing enhancement ratio (SER) was 1.795. UBE2T overexpression decreased the radiosensitivity of SPC-A-1 lung adenocarcinoma cells with an SER of 0.293. γH2AX foci number per cell were significantly increased in UBE2Tsh A549 cells after irradiation ( P<0.01) . Compared with the control group, the expression level of γH2AX protein was up-regulated ( P<0.01)and that of Rad51 protein was down-regulated in UBE2Tsh A549 cells after radiation ( P<0.001). Compared with the control group, the expression level of γH2AX protein was down-regulated ( P<0.05) and that of Rad51 protein was up-regulated in UBE2T overexpressed SPC-A-1 cells ( P<0.001). The proportion of UBE2Tsh A549 cells in G 2 phase was decreased ( P<0.01) and cell apoptosis was increased ( P<0.001). Conclusions:UBE2T might promote the radioresistance of lung adenocarcinoma cells by enhancing DNA DSB repair induced by radiotherapy, inducing cell cycle G 2 phase arrest, and reducing cell apoptosis.

The Continuity Assessment Record and Evaluation (CARE) in America is a comprehensive tool for continuously and consistently evaluating and recording patients' care needs. CARE can objectively reflect care level, build payment basis, monitor service quality and support the exchange and sharing of health data striding across different service organizations. Its ultimate objective is to establish a continuous service system taking the single assessment instrument as integration mechanism, based on needs, connecting acute medical care, post-acute care and long-term care. This paper introduced the development background and process of CARE as well as its composition and application, and this paper also explored its reference for establishing an assessment system which adapted to the situation of our country so as to promote the establishment of "people-centered" medical service and elder care service integration system.
