Objective To analyze the psychological status and related factors in elderly patients of different genders after percutaneous coronary intervention(PCI)for coronary heart disease(CHD).Methods A total of 303 eligible patients treated in our department from January 2021 to December 2024 were enrolled,and then divided into a male group(154 cases)and a female group(149 cases).Based on the 7-item Generalized Anxiety Disorder Scale,they were assigned into a female anxiety group(97 cases),a female non-anxiety group(52 cases),a male anxiety group(82 cases)and a male non-anxiety group(72 cases).According to the 9-item Patient Health Questionnaire,they were alsocategorized into a female depression group(92 cases),a female non-depression group(57 cases),a male depression group(75 cases)and a male non-depression group(79 cases).The basic clinical data and results of psychological assessment were recorded in each group.Statistical analysis was performed on the indicators,including total cholesterol(TC),triglyceride(TG),low-density lipoprotein cholesterol(LDL-C)and high density lipoprotein cholesterol(HDL-C).Results The female patients had significantly higher scores of physical symptoms,anxiety and depression,and larger proportions of anxiety and depression than the male group(P＜0.05,P＜0.01).In the female patients,advance age,higher TC,TG and LDL-C levels and somatic symptom score were observed in those with anxiety than those without,and in those with depression group than those without(P＜0.05,P＜0.01).The male anxiety group exhibited older age,more lesion vessels,larger ratio of ≥2 stents,and higher physical symptom score when compared with the male non-anxiety group,and so were in the male depression group than the male non-depression group(P＜0.05,P＜0.01).Binary logistic regression analysis showed that age,TC,LDL-C,and somatic symptom score were risk factors for anxiety,and age,TC,HDL-C,LDL-C,and somatic symptom score were risk factors for depression in elderly female CHD patients(P＜0.05,P＜0.01).For the elderly male CHD patients,age,stents ≥2,and somatic symptom score were risk factors for anxiety(OR=1.068,95％CI:1.002-1.138,P＜0.05;OR=6.458,95％CI:2.807-14.858,P＜0.01;OR=1.148,95％CI:1.045-1.262,P＜0.01),and age,stents ≥2,and more lesion vessels were risk factors for depression(P＜0.01).Conclusion The female CHD patients undergoing PCI have higher anxiety and depression scores than the male patients.There are certain differences in the influencing factors for anxiety and depression between genders.Effective control of these risk factors may help improve the prognosis of CHD patients after PCI.

Objective: To analyze the longitudinal association between mobile phone dependence and depressive symptoms in college students, so as to provide a theoretical basis for psychological health education among college students. Methods: From November 2021 to June 2023, 2 515 first year students from 2 universities in Yunnan Province were surveyed with a questionnaire by a cluster random sampling method, including baseline survey (November 2021, T1) and three follow up visits (June 2022, T2; November 2022, T3; June 2023, T4). The Self rating Questionnaire for Adolescent Problematic Mobile Phone Use and the Depression Anxiety Stress Scales-21 (DASS-21) were used to evaluate mobile phone dependence and depressive symptoms of college students. The χ 2 test was used to analyze the difference in depressive symptoms among different demographic groups, and a generalized estimation equation model was established to analyze the association between mobile phone dependence symptoms and depressive symptoms. Results: The detection rates of depressive symptoms among university students in Yunnan Province at time points T1, T2, T3, and T4 were 23.02%, 33.36%, 34.79% and 35.51%, respectively. There were statistically significant differences in the detection rates of depressive symptoms among college students with different sacademic burden (T1, T2, T3, T4), different number of close friends (T1, T2, T3), as well as their father s educational level (T1), mothers educational level (T2, T4), gender (T4), major (T3, T4), education (T2, T3, T4), family residency (T1, T2), and family economic conditions (T1, T2, T4) ( χ 2= 59.68 , 49.38, 16.70, 39.31; 55.35, 26.01, 16.69; 10.22; 14.87, 11.51; 14.90; 27.81, 50.28; 9.75, 7.42, 24.76; 6.06, 4.47 ; 15.88, 14.58, 15.85, P < 0.05 ). After controlling for demographic variables and confounding factors in the generalized estimation equation model, mobile phone dependence ( β =0.11), withdrawal symptoms of mobile phone dependence ( β =0.14), and the physical and mental effects of mobile phone dependence ( β =0.14) were all positively correlated with depressive symptoms ( P <0.01). Further gender analysis showed that depressive symptoms in both boys ( β =0.13, 0.13, 0.18) and girls ( β =0.10, 0.13, 0.13 ) were associated with mobile phone dependence, withdrawal symptoms of mobile phone dependence and the physical and mental effects of mobile phone dependence ( P <0.01). Conclusions Depressive symptoms of college students are positively correlated with mobile phone dependence, and family economic conditions, academic burden and number of close friends are factors that continued to affect depressive symptoms. College students should be guided to pay attention to the impact of excessive use of mobile phones on their physical and mental health, use mobile phones reasonably to reduce the incidence of depressive symptoms among college students.

Objective:To explore the clinical and genetic characteristics of two children with mental retardation and microcephaly.Methods:Two children who had visited the Anhui Children′s Hospital respectively on March 12 and June 22, 2021 were selected as the study subjects. Peripheral venous blood samples were collected from them and their parents, and subjected to chromosomal karyotyping and whole exome sequencing analyses. Candidate variants were verified by Sanger sequencing and pathogenicity analysis. This study was approved by the Anhui Children′s Hospital (Ethics No. EYLL-2018-008).Results:Chromosomal karyotyping and copy number detection of the two children had found no abnormality. Whole exome sequencing revealed that child 1 has harbored a c. 471delT (p.Pro157Profs*9) frameshifting variant of the CASK gene, whilst child 2 has harbored a c. 1259_1269delCTGAGAATAAC (p.Pro420fs*27) frameshifting variant of the CASK gene. Sanger sequencing confirmed that both variants were de novo in origin. Based on the guidelines from the American College of Medical Genetics and Genomics and the Association for Molecular Pathology (ACMG-AMP), both variants were rated as pathogenic (PVS1+ PS2+ PP3). Conclusion:The de novo variants of the CASK gene probably underlay the pathogenesis of mental retardation and microcephaly in both children.

AIM: Endothelial progenitor cells(EPCs) are a group of stem cells/progenitor cells,which exist in postnatal body and can be of specially homing to the foci of angiogenesis and then differentiate into endothelial cells.This investigation was to study the method for culturing endothelia progenitor cells(EPCs) in vitro,and to observe its feasibility and condition formed vessel-like structure.METHODS: The cells were isolated from born marrow,peripheral blood,umbilical cord blood or spleen in different laboratories.The EPCs derived from human umbilical cord blood and rabbit peripheral blood were cultured in vitro through adhesion selection and were differentiated into endothelial cells under the induction of special cytokines.The expression of CD34,VEGFR-2,AC133 and VE-cadherin were detected by fluorescence-activated cell sorting.The endothelial cell lineage was confirmed by DiI-ac-LDL up-taking and Ⅷ factor immunocytochemistry.RESULTS: The EPCs derived from human umbilical cord blood and rabbit peripheral blood were cultured in vitro successfully,forming cord-like and tube-like structure.The EPCs derived from rabbit peripheral blood differentiated more mature and formed vessel-like structure.CONCLUSION: The EPCs derived from human umbilical cord blood and rabbit peripheral blood formed vessel-like structure in vitro.EPCs may be a potential resource of vessel tissue engineering.
