Objective To investigate the prevalence status and influencing factors of metabolic syndrome (MS) in adult patients with hypopituitarism (HP) during hospitalization. Methods The data of adult HP patients who received treatment in the hospital were collected from March 2021 to March 2024. The prevalence status of MS in adult HP patients was counted, and logistic regression analysis was adopted to analyze the influencing factors of MS in adult HP patients. Results Among the 308 adult HP patients in this study, 121 cases developed MS and 187 cases did not develop MS, and they were included in the MS group (n=148) and the non-MS group (n=232). The incidence of MS in adult HP patients was 38.95% (148/380). Compared with the non-MS group, the levels of high-density lipoprotein cholesterol, serum total cholesterol and low-density lipoprotein cholesterol in the MS group were higher, the waist circumference was larger, and the growth hormone was lower (P<0.05). After logistic regression analysis, it was found that high-density lipoprotein cholesterol (OR=1.069, 95%CI: 1.010-1.132, P=0.021), total serum cholesterol (OR=1.065, 95%CI: 1.014-1.119, P=0.012), low-density lipoprotein cholesterol (OR=1.055, 95%CI: 1.005-1.108, P=0.031), waist circumference (OR=1.063, 95%CI: 1.006-1.123, P=0.030) and growth hormone (OR=1.077, 95%CI: 1.019-1.138, P=0.009) could independently affect the occurrence of MS in adult HP patients (P<0.05). Conclusion Adult HP patients during hospitalization are often complicated with MS. High-density lipoprotein cholesterol, serum total cholesterol, low-density lipoprotein cholesterol, waist circumference, and growth hormone are factors affecting the occurrence of MS in adult HP patients.

Objective To explore the eye behaviors and myopia-related risk factors among primary and secondary school students in Tianjin,in order to carry out targeted eye health education and guidance.Methods A cross-sectional study was conducted.In December 2021,an eye health questionnaire was distributed to primary and secondary school students in Tianjin to investigate their eye habits;combined with the campus vision screening data in the second half of 2021,a multivariate logistic regression analysis model was constructed to explore the risk factors related to myopia.Re-sults A total of 821 459 questionnaires were collected,including 701 104 valid questionnaires.The usage time of electron-ic learning products and electronic entertainment products for primary school students was mostly less than 1 hour(ac-counting for 57.74％and 40.98％,respectively).The population of junior high school students who spend more than 2 hours using electronic learning products and electronic entertainment products(accounting for 26.61％and 35.05％,re-spectively)significantly increased compared to primary school students(accounting for 11.21％and 20.93％,respective-ly).Most senior high school students spend more than 2 hours daily using electronic devices for learning and entertainment purposes,as well as reading paper materials.51.59％of primary school students do not meet the standard for sleep dura-tion,while the rate of reaching the standard sleep duration of junior high and senior high school students was 60.09％and 64.99％,respectively.Most(55.74％)primary and secondary school students have an average outdoor activity duration of 1-2 hours daily.The results of multivariate logistic regression analysis showed that the risk of myopia in primary school students was correlated with the time spent using electronic products(including learning and entertainment),the time spent reading paper materials at a close range,outdoor activities,time to fall asleep,and sleep duration(all P＜0.05);the risk of myopia among junior high school students was related to the time spent using electronic entertainment products,reading paper materials at a close range,outdoor activities,and sleep duration(all P＜0.05);the risk of myopia among senior high school students was only related to the time spent reading paper materials at a close range and the duration of outdoor activities(both P＜0.05).Conclusion The proportion of primary school students,junior high school students and senior high school students in Tianjin who use electronic products for more than 2 hours is gradually increasing,and the rate of reaching the standard sleep duration is gradually increasing.The risk of myopia among these students is related to the time spent reading paper materials at a close range and outdoor activities.Science popularization should be carried out and management of eye behaviors should be strengthened in the whole society to reduce myopia rates in children and adolescents in China.

Objective To explore the material basis and mechanism of the Chinese medicine Dingqing tablets in the treatment of leukemia.Methods The potential active ingredients of Dingqing tablets were retrieved through TCMSP and HERB Database and the targets of herbs were screened by Swiss TargetPrediction databases.The treatment targets of leukemia were searched from the GeneCards,OMIM and Disgenet databases.The protein-protein interaction network was used to construct the interactive target regulation function of Dingqing tablets and leukemia by STRING software,and the core subnetworks were filtered by the MCODE plug-in.A component-target pathway network was constructed by GO and KEGG enrichment analysis of the highest scoring Gene cluster 1 gene in the DAVID database.Molecular docking of the active components and core targets of Dingqing tablets was performed by AutoDock and the results were visualized.Results A total of 82 active ingredients and 439 targets of action of Dingqing tablets,and 1 878 leukemia-related targets were obtained through database retrieval,in which 169 common targets of active ingredients and diseases were mapped.Based on the degree values,the main active ingredients were determined as quercetin,luteolin,kaempferol,etc.The PPI core network indicated that the key targets for treating leukemia included TP53,MMP9,TNF,AKT1,CASP3,etc.The gene enrichment analysis of sub-networks and the component-target pathway network diagram showed that Dingqing tablets might exert therapeutic effects on leukemia by regulating signaling pathways such as TNF and IL-17.The molecular docking results showed fairly strong binding activity between the active ingredients and the targets.Conclusion The active ingredients of Dingqing tablets may participate in TNF,IL-17,and other signaling pathways by regulating genes such as TP53,AKT1,and CASP3,thereby exerting therapeutic effects on leukemia.

Objective To screen self-assessed differentially expressed genes of cataracts and cataract-related genes from the International Mouse Phenotyping Consortium(IMPC),Mouse Genome Informatics(MGI),Cat-Map and GWAS Catalog and perform bioinformatics analysis,exploring potential pathogenic genes and signaling pathways in cataract patho-genesis.Methods The transparent anterior lens capsules of cataract patients and personnel in the control group were collected,total ribonucleic acid(RNA)was extracted,the library was constructed for sequencing,and differentially ex-pressed genes were analyzed.Data about the cataract phenotype-related genes was downloaded from IMPC,MGI and GWAS Catalog,the latest data from Cat-Map was downloaded,cataract susceptible gene annotation was performed,the characteristics of data from each database and the differentially expressed genes were analyzed,and Gene Ontology enrich-ment analysis,Kyoto Encyclopedia of Genes and Genomes enrichment analysis and protein-protein interaction(PPI)net-work analysis were carried out.Results Cataract susceptible single nucleotide polymorphism(SNP)annotation found a total of 21 potential target genes.IMPC,MGI,Cat-Map,and SNP target genes were enriched in the regulation of RNA poly-merase promoters,protein binding,cell division,peroxisome,and cell metabolism.The PPI network of core proteins fo-cused on the peroxisome family and function-related genes.The differentially expressed genes obtained from sequencing da-ta of transparent anterior lens capsules of cataract patients and personnel in the control group were enriched in mitogen-ac-tivated protein kinase(MAPK)signaling pathway,signal transduction,ion transport,metabolism,peroxisome,and cell adhesion pathways.Compared with the sequencing differentially expressed data of cataract patients,the differentially ex-pressed genes obtained from IMPC,MGI,Cat-Map,and SNP target gene sets were enriched in intracellular signal transduc-tion,MAPK signaling pathway,circadian rhythm,cyclic adenosine monophosphate,and calcium pathway.TRIM22,OAS3,EPSTI1,ZC3HAV1,SP110 and PARP12 protein networks of cataracts were identified based on the PPI networks.Conclu-sion The pathways and biological functions involved in the PPI networks of TRIM22,OAS3,EPSTI1,ZC3HAV1,SP110 and PARP12 may be a new pathogenic mechanism for cataracts.

Objective:To explore the association between cognitive function and the level of gamma-amino-butyric acid(GABA)in anterior cingulate cortex(ACC)before and after treatment in patients with major depres-sion disorder.Methods:Totally 31 medication-naive patients with major depression disorder meeting the criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)and 33 normal controls were col-lected.Each eligible patient received treatment with selective serotonin reuptake inhibitor agents for 8 weeks.The MATRICS Consensus Cognitive Battery(MCCB)was used to evaluate the cognitive function.By means of 1H magnetic resonance spectroscopy,anterior cingulate cortex GABA concentrations were measured.Results:At base-line,the concentration of ACC GABA relative to water(GABA+/W)was lower in the patient group than in the control group(P＜0.05)and increased after treatment(P＜0.05).ACC GABA+/W was negatively associated with verbal learning and visual memory score in patient group at baseline(correlation coefficient and P value were r=-0.40,P＜0.05;r=-0.42,P＜0.05,respectively).The ACC GABA+/W difference resulted of treatment in patient group was positively associated with the difference of working memory score and the difference of reasoning and problem-solving score(correlation coefficient and P value were r=0.58,P＜0.05;r=0.66,P＜0.05,respec-tively).Conclusion:The cognitive dysfunction of patients with major depression disorder may not be related to the degree of depression and anxiety.And improvement of cognitive function may be associated with increase of ACC GABA concentrations.

【Objective】 In recent years, granulocyte colony stimulating growth factor (G-CSF) has been proved to be expressed in the posterior capsule of the lens of posterior capsular opacification (PCO), but its specific role remains unclear. The purpose of this study was to explore whether G-CSF plays a role in PCO. 【Methods】 First, human lens epithelial cells (HLEC-B3) were treated with different concentration of recombinant G-CSF protein and screened for effective appropriate concentration. Then, Western blotting was used to detect the effects of extracellular matrix (ECM) synthesis and epithelial mesenchymal transdifferentiation (EMT) marker genes after G-CSF treatment on HLEC-B3 cells. Finally, the effects of G-CSF treatment on the migration and invasion of HLEC-B3 cells were detected by scratch experiment and Transwell test. 【Results】 G-CSF at 80 μg/L could promote the proliferation of HLEC-B3 cells. After G-CSF was treated for 48 h, the expressions of EMT and ECM synthesis marker genes in HLEC-B3 cells were significantly upregulated with time. G-CSF could significantly promote HLEC-B3 cell invasion after 48 h induction. Similarly, G-CSF could also significantly induce cell migration compared to the CTRL group. 【Conclusion】 G-CSF can promote the proliferation, migration and invasion of HLEC-B3 cells, as well as EMT and ECM synthesis, which might be involved in the occurrence of PCO. Inhibiting the expression of G-CSF may be a new strategy for PCO prevention.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

Objective:To develop the Peristome Skin Injury Risk Assessment Scale and to verify its reliability, validity and predictive performance in patients with colorectal cancer stoma.Methods:The initial assessment scale was developed through literature review and Delphi expert consultation. From February 2020 to April 2021, convenient sampling was used to select 290 cases of colorectal cancer stoma patients who were reexamined in the Oncology Surgery of the First Affiliated Hospital of Xi'an Jiaotong University as the research object. Item analysis, validity analysis, reliability analysis, receiver operating characteristic curve (ROC) were used to test the reliability, validity and predictive performance of the scale.Results:Exploratory factor analysis extracted a total of 4 common factors, namely general condition, stoma condition, postoperative condition, education and self-care condition, a total of 17 items, and the cumulative variance contribution rate was 85.144%. The scale-level content validity index was 0.941, and the item-level content validity index was 0.857 to 1.000. The Cronbach's α coefficient of the total scale was 0.824, the split-half reliability coefficient was 0.837, and the test-retest reliability coefficient was 0.819. There was a statistically significant difference in the scores of the Peristome Skin Injury Risk Assessment Scale in patients with colorectal cancer stoma between the injury group and the non-injury group ( P<0.05) . The area under the ROC curve was 0.838 (95% confidence interval: 0.785-0.891) . When the cut-off score was 39.5, the sensitivity of the scale was 0.849, the specificity was 0.759, the Youden index was 0.608, and the predictive performance was the best. Conclusions:The Peristome Skin Injury Risk Assessment Scale has good reliability and validity, and has high predictive performance, which is suitable for the assessment of the risk of peristome skin injury in patients with colorectal cancer in China.

Objective:To evaluate the clinical effectiveness and safety of three different non-invasive ventilation strategies in initial treatment of neonatal respiratory distress syndrome(RDS).Methods:A total of 111 premature infants with RDS who were admitted to the NICU from Jan 2019 to Dec 2019 were divided into nasal continuous positive airway pressure(NCPAP)group( n=35), bi-level positive airway pressure(BiPAP)group( n=30)and nasal intermittent positive pressure ventilation(NIPPV)group( n=46)as an initial respiratory support.A retrospective study was conducted to compare pH, PaCO 2, PaO 2, P/F value(PaO 2/FiO 2)before 4 to 6 hours after treatment, the incidence of non-invasive ventilation failure, non-invasive ventilation time, invasive ventilation time, duration of oxygen therapy and the incidence of complications among the three groups. Results:Four to 6 hours after treatment, the blood gas indexes of pH, PaO 2 and P/F were significantly higher and PaCO 2 was significantly lower than those before the treatment in the three groups ( P<0.05). PaO 2 and P/F in both BiPAP group and NIPPV group were higher than those in NCPAP group ( P<0.05). PaCO 2 was lower in BiPAP group than that in NCPAP group ( P<0.05), but there were no statistical differences of the blood gas indexes between BiPAP group and NIPPV group ( P>0.05). The incidence of non-invasive ventilation failure was significantly lower in the BiPAP group and NIPPV group than that in NCPAP group ( P<0.012 5), while no signifficant difference was observed between BiPAP group and NIPPV group ( P>0.05). Moreover, no signifficant differences were found among three groups regarding non-invasive ventilation time, ventilation time of successful non-invasive ventilation, invasive ventilation time, duration of oxygen therapy and the incidence rates of bronchopulmonary dysplasia, necrotizing enterocolitis, periventricular-intraventricular hemorrhages, retinopathy of prematurity( P>0.05). Conclusion:NIPPV and BiPAP as an initial respiratory support for RDS in preterm infants augment the beneficial effects of NCPAP contributing to improvement of oxygenation, reduction of the rate of intubation within five days postnatal life without the relevant complications.
