Objective:To explore the interaction needs between depressed adolescents with non-suicidal self-injury behavior and their parents.Methods:From June to November 2023, purposive sampling was used to select depression adolescents with non-suicidal self-injury behavior and their parents admitted to Huai'an Third People's Hospital as respondents. The semi-structured interview was used to collect data. The paired interview and Colaizzi 7-step analysis methods were used to analyze and summarize interview data.Results:Fifteen pairs of adolescents and their parents were interviewed. The needs of depressed adolescents with non-suicidal self-injury behavior for parental attention were summarized as controlling emotions, empathetic perception, reducing stress, mental dependence, autonomous decision-making, and mutual respect. The needs of parents for depressed adolescents with non-suicidal self-injury behavior were summarized as overcoming depression, restoring education, emotional response, actively seeking help, deep communication, and easing relationships.Conclusions:There are various interactive needs between depressed adolescents with non-suicidal self-injury behavior and their parents, which are closely related but contradictory in coping with the illness. It is recommended that medical and nursing staff conduct research on patients and their parents as a whole and provide personalized and targeted two-way guidance and emotional support through in-depth understanding and careful consideration of the multi-level interaction needs of both parties.

Objective:To investigate the clinical characteristics and survival analysis of myelodysplastic syndromes(MDS)with RUNX1 gene mutation.Methods:Clinical data of 177 newly diagnosed MDS patients admitted to the Department of Hematology,the Second Affiliated Hospital of Air Force Military Medical University from October 1,2015 to October 31,2022 were retrospectively analyzed.Gene mutation detection was performed by second-generation sequencing technology,and clinical characteristics and prognosis of patients with RUNX1 gene mutation were analyzed.Results:A total of 30 cases(16.95％)of RUNX1 gene mutations were detected,including 15 missense mutations(50.0％),9 frameshift deletion mutations(30.0％),4 splice site mutations(13.3％),1 insertion mutation(3.3％),and 1 nonsense mutation(3.3％).Patients with RUNX1 mutations had a median age of 68.5 years at diagnosis(range:62.25-78.50 years old).There were no significantly differences between RUNX1 mutations and wild type patients in age distribution,gender,peripheral blood white blood cell count,hemoglobin level,bone marrow and peripheral blood blasts ratio,IPSS-R cytogenetics,IPSS-R stage,etc.(P＞0.05).However,there were statistically significant differences in platelet count and whether complicated karyotype.Compared with patients without RUNX1 gene mutation,patients with RUNX1 gene mutation had lower platelet count(P=0.018),and were less likely to have complicated karyotype at initial diagnosis(P=0.01).Cox proportional hazards model analysis showed that when other co variates remained unchanged,the higher the platelet count,the better the survival of patients(HR=0.995,95％CI:0.990-0.999,P=0.036);In the IPSS-M prognostic stratification,keeping other covariates unchanged,the risk of progression or death of myelodysplastic syndrome was significantly lower in the medium to high-risk and low-risk groups compared with the high-risk group(HR=0.149,95％CI:0.031-0.721,P=0.018;HR=0.026,95％CI:0.003-0.234,P=0.001).Survival analysis showed that MDS patients with RUNX1 gene mutation had worse overall survival time(P＜0.001).Patients with RUNX1 mutation had worse OS than non-mutation patients in the early WHO group.RUNX1 mutation and IPSS-M risk stratification mean OS and mean LFS were worse in low-risk patients than in non-mutated patients.Conclusion:RUNX1 gene mutation is an adverse prognostic factor in MDS patients,especially in the IPSS-M prognosis stratification group of low-risk,medium-low risk,medium-high risk and WHO classification of early patients.

AIM To explore the ameliorative effects of Zigui Yichong Formula on mitochondrial energy metabolism in in vitro model of premature ovarian insufficiency (POI).METHODS A POI model in vitro was established in human ovarian granulosa cell KGN with acrolein ( ACR ) for the further intervention of serum containing Zigui Yichong Formula.The control group,the ACR group,the Zigui Yichong Formula group,the EX527 ( SIRT1 inhibitor) group and the EX527+Zigui Yichong Formula group were set up.The cells had their apoptosis rate detected by flow cytometry;their ROS level detected by DCFH-DA method;their mitochondria number detected by Mito-Trakine fluorescence labeling method;their oxidative phosphorylation level of mitochondria detected by Seahorse method;their ATP level detected by colorimetry;their copy number of mtDNA and mRNA expressions of SIRT1,PGC-1α,Nrf1 and TFAM detected by RT-qPCR;and their protein expressions of SIRT1,PGC-1α,Ac-PGC-1α,Nrf1 and TFAM detected by Western blot.RESULTS Compared with the control group,the ACR group displayed increased apoptosis rate and ROS level of KGN cells ( P<0.05,P<0.01 );decreased number of mitochondria and mtDNA copy number ( P<0.01 );decreased basic value of mitochondrial aerobic respiration,maximum respiration,reserve value and ATP level (P<0.05,P<0.01),decreased mRNA and protein expressions of SIRT1,PGC-1α,Nrf1 and TFAM ( P<0.05,P<0.01 );and increased protein expression of Ac-PGC-1α( P<0.01 ).Compared with the ACR group,the Zigui Yichong Formula group demonstrated improvement in terms of the aforementioned indices levels ( P<0.05,P<0.01).The combination use of Zigui Yichong Formula and EX527 reversed the effects of single use of Zigui Yichong Formula on KGN cells ( P<0.05,P<0.01).CONCLUSION Zigui Yichong Formula may improve the mitochondrial energy metabolism disorder induced by ACR in KGN cells by increasing mitochondrial biosynthesis via SIRT1/PGC-1α signaling pathway.

OBJECTIVE: To study the impacts of varicocele (VC) and varicocelectomy (VCT) on the proteomics of rat testis tissue, and to analyze the differential proteins and signaling pathways, and observe the microstructural changes of the testis tissue. METHODS: We selected 60 male SD rats and divided them into a sham operation (SO), a VC model control, and a VCT group. We harvested the testis tissues from the rats at 4 weeks after modeling for determination of the differential protein expressions by mass spectrometry, analysis of the changes in the protein signaling pathways by KEGG pathway repolarization, and observation of the microstructural changes in the spermatogenic cells under the transmission electron microscope (TEM). RESULTS: A total of 15 clinically significant proteins were effectively identified, among which RPS24, KIFAP3, HPX, RPL38, TOP2A, PRPF19, TRPM3, RPL32, CNBP and AHSG were upregulated, while RPS9, TKFC, SH3BGRL3, ACAA2 and FABP3 downregulated. The differential pathways found included the Type-I 4-aminobutyrate degradation pathway, eIF2 signaling pathway, and Type-III glutamate degradation pathway, which were all related to the pathogenesis of testicular growth arrest. Compared with the rats in the VCT group, those of the VC group rats showed ultrastructural changes in the testis tissue under the TEM, such as mitochondrial vacuolar degeneration, dense nucleoli, invagination of cell nuclear membranes, and irregularity, which were detrimental to the survival of testicular cells. CONCLUSION VCT affects the development and growth of the testis by altering the expressions of relevant proteins and influencing the changes of the gene pathways in the testicular cells, which may be one of the causes of VC inducing testis injury and testicular spermatogenic dysfunction. The changes in these molecular pathways can provide some theoretical evidence for an insight VC as well as potential therapeutic targets for its treatment.

Objective:To deeply understand parents' cognition and psychological experience towards depressive disorder in adolescents with non-suicidal self-injury behavior.Methods:This study was a qualitative study. Using the purposive sampling method, semi-structured interviews were conducted with 12 parents of adolescents with depressive disorder and non-suicidal self-injury admitted to Huaian Mental Health Center from June to October 2022. Colaizzi 7-step analysis method was used to analyze the interview data.Results:Parents' cognition and psychological experience of adolescent depressive disorder with non-suicidal self-injury behavior was extracted into 3 themes, namely, insufficient cognition of the disease, experience of various negative emotions and desire for multiple support and help.Conclusions:Parents generally lack understanding and have cognitive misconceptions about the related knowledge of adolescent depressive disorder with non-suicidal self-injury behavior and have severe negative emotions. It is suggested that the medical staff should pay attention to the cognition and psychological experience of the parents, and construct and improve the management system of adolescents with depression disorder accompanied by non-suicidal self-injury behavior, so as to reduce the risk of self-injury and suicide of the children.

OBJECTIVE: To investigate the characteristics of gene mutation, clinical characteristics and significance in acute leukemia (AL) patients. METHODS: The clinical data of 102 AL patients in Hebei General Hospital from September 2016 to September 2020 were collected and analyzed retrospectively, including the characteristics of gene mutation, age, peripheral blood cells, bone marrow blasts, leukemia subtypes and myeloperoxidase (MPO). RESULTS: The total gene mutation rate was 87.25% (89/102) in all 102 patients. A total of 275 gene mutations were detected, with an average of 2.70 gene mutations per patient. The most frequent mutations of 102 patients were as follows: CEBPA (6.91%), NPM1 and ASXL1(6.18%), TET2 (5.82%), DNMT3A (5.45%), IDH2 and FLT3-ITD (5.09%). Gene mutations often occurred simultaneously. CEBPA mutation occurred in 10 cases of M2 subtype, while TET2 mutation occurred in 9 cases of M2 subtype. Among the most common gene mutations in MPO low expression group, mutation rates of NPM1, DNMT3A, IDH2, SF related gene mutation and RUNX1 were significantly different than those in MPO high expression group (all P<0.05). Univariate analysis showed that age, NPM1, DNMT3A and FLT3-ITD had significant effects on leukocyte level. Logistic regression analysis showed that patients with positive NPM1 mutations may had higher leukocyte levels (p=0.038), and those with positive DNMT3A mutations may had higher platelet levels (p=0.042). CONCLUSION The incidence of gene mutation in patients with AL is high, and it often occurs simultaneously. CEBPA and TET2 gene mutations are more common in M2 subtype. In patients with MPO low expression, the most common gene mutations are NPM1, DNMT3A and IDH2. AL patients with NPM1 gene mutation had higher white blood cell levels, while with DNMT3A gene mutation had higher platelet levels.
