The AP2/ERF transcription factor family is a class of transcription factors widely present in plants, playing a crucial role in regulating flowering, flower development, flower opening, and flower senescence. Based on transcriptome data from flower, leaf, and stem samples of two Lonicera macranthoides varieties, 117 L. macranthoides AP2/ERF family members were identified, including 14 AP2 subfamily members, 61 ERF subfamily members, 40 DREB subfamily members, and 2 RAV subfamily members. Bioinformatics and differential gene expression analyses were performed using NCBI, ExPASy, SOMPA, and other platforms, and the expression patterns of L. macranthoides AP2/ERF transcription factors were validated via qRT-PCR. The results indicated that the 117 LmAP2/ERF members exhibited both similarities and variations in protein physicochemical properties, AP2 domains, family evolution, and protein functions. Differential gene expression analysis revealed that AP2/ERF transcription factors were primarily differentially expressed in the flowers of the two L. macranthoides varieties, with the differentially expressed genes mainly belonging to the ERF and DREB subfamilies. Further analysis identified three AP2 subfamily genes and two ERF subfamily genes as potential regulators of flower development, two ERF subfamily genes involved in flower opening, and two ERF subfamily genes along with one DREB subfamily gene involved in flower senescence. Based on family evolution and expression analyses, it is speculated that AP2/ERF transcription factors can regulate flower development, opening, and senescence in L. macranthoides, with ERF subfamily genes potentially serving as key regulators of flowering duration. These findings provide a theoretical foundation for further research into the specific functions of the AP2/ERF transcription factor family in L. macranthoides and offer important theoretical insights into the molecular mechanisms underlying floral phenotypic differences among its varieties.

OBJECTIVES: To explore the mediating role of sleep duration in the relationship between depression symptoms and myopia among middle school students. METHODS: This study was a cross-sectional research conducted using a stratified cluster random sampling method. A total of 1 728 middle school students were selected from two junior high schools and two senior high schools in certain urban areas and farms of the Xinjiang Production and Construction Corps. Questionnaire surveys and vision tests were conducted among the students. Spearman analysis was used to analyze the correlation between depression symptoms, sleep duration, and myopia. The Bootstrap method was employed to investigate the mediating effect of sleep duration between depression symptoms and myopia. RESULTS: The prevalence of myopia in the overall population was 74.02% (1 279/1 728), with an average sleep duration of (7.6±1.0) hours. The rate of insufficient sleep was 83.62% (1 445/1 728), and the proportion of students exhibiting depression symptoms was 25.29% (437/1 728). Correlation analysis showed significant negative correlations between visual acuity in both eyes and sleep duration with depressive emotions as measured by the Center for Epidemiologic Studies Depression Scale (with correlation coefficients of -0.064, -0.084, and -0.199 respectively; P<0.01), as well as with somatic symptoms and activities (with correlation coefficients of -0.104, -0.124, and -0.233 respectively; P<0.01) and interpersonal relationships (with correlation coefficients of -0.052, -0.059, and -0.071 respectively; P<0.05). The correlation coefficients for left and right eye visual acuity and sleep duration were 0.206 and 0.211 respectively (P<0.001). Sleep duration exhibited a mediating effect between depression symptoms and myopia (indirect effect=0.056, 95%CI: 0.029-0.088), with the mediating effect value for females (indirect effect=0.066, 95%CI: 0.024-0.119) being higher than that for males (indirect effect=0.042, 95%CI: 0.011-0.081). CONCLUSIONS Sleep duration serves as a partial mediator between depression symptoms and myopia in middle school students.

Objective To investigate the clinical efficacy and safety of single-port thoracoscopic surgery for elderly patients with non-small cell lung cancer(NSCLC).Methods The clinical data of 93 patients with NSCLC who underwent thoracoscopic lobectomy or segmentectomy was collected,the patients were divided into uniportal operation group(40 cases,received single-port thoracoscopic surgery)and single-operation port operation group(53 cases,received single-operation port thoracoscopic surgery)according to the operation methods.The operation time,the amount of blood loss,the number of lymph node dissection,chest drainage volume 3 days after surgery,duration of indwelling drainage tube,postoperative hospital stay,visual analogue scale(VAS)score of postoperative pain,and incidence of postoperative complications of patients between the two groups were compared.The cumulative survival rate between the two groups was compared.Results The operation were successfully completed in both groups.There was no statistically significant difference in terms of operation time,the amount of blood loss,the number of lymph node dissection,chest drainage volume 3 days after surgery,duration of indwelling drainage tube,or postoperative hospital stay of patients between the two groups(P>0.05).There was significant difference in VAS score of postoperative pain of patients between the two groups(P<0.05).There was no early death within 1 months after surgery in both groups.There was no significant difference in the incidence of complications between the two groups(P>0.05).After 4 to 30 months of follow-up,there was no significant difference in the cumulative survival rate between the two groups(P>0.05).Conclusion Single-port thoracoscopic lobectomy or segmentectomy for elderly patients with NSCLC has high safety and feasibility,with less trauma,faster recovery and less postoperative pain.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Objective To explore the diagnosis and clinical characteristics of atypical severe pneumonia caused by Chlamydia abortus(C.abortus).Methods Clinical data of 4 patients diagnosed with atypical severe pneumonia caused by C.abortus in a hospital from January 2021 to November 2022 were collected.Clinical characteristics,dia-gnosis and treatment,and precautions of the disease were comprehensively analyzed.Results All 4 patients were male,aged 63-73 years old,with acute onset,high fever,cough and expectoration.Three patients had a history of contact with poultry,one patient had a history of contact with abortion goat.The interval between the emerging of clinical symptoms and the onset of acute respiratory failure in 4 patients was 1-6 days,and the oxygenation index(PaO2/FiO2)at admission was less than 200 mmHg,which gradually decreased with the progression of the disease,active support with a ventilator was necessary.Two patients had an increase in white blood cell count,4 had an in-crease in neutrophil percentage,3 had a mild decrease in platelet count.Among 4 patients,2,2,3 and 4 patients showed elevated levels of aspartate aminotransferase,alanine aminotransferase,creatine kinase,and serum creati-nine respectively,2 patients had mild hyponatremia,4 patients showed significant increase in C-reactive protein,procalcitonin,and interleukin-6 levels.Four patients'chest CT findings showed main involvement of single or mul-tiple lung lobes,with exudation and consolidation,and later involvement of multiple lobes of lung.The metageno-mic next-generation sequencing of bronchoalveolar lavage fluid detected the DNA sequence of C.abortus.Based on the clinical manifestations,contact history,chest CT,and metagenomic next-generation sequencing results of 4 pa-tients,the diagnosis was C.abortus.atypical severe pneumonia.After timely adjustment of the treatment of anti-in-fection regimen based on doxycycline,the patients'condition improved and were discharged.Conclusion C.abor-tus may also cause human pneumonia,which can lead to serious clinical outcome after infection.Patient had a histo-ry of animal contact should be alert to such diseases.Metagenomic next-generation sequencing can detect C.abortus.

Hypertension and its associated cardiovascular diseases such as stroke and ischemic heart disease result in a high burden of disease and health losses, making it the most burdensome disease in the world and one of the important public health issues in China. Currently Chinese scholars have carried out a large number of studies on the prevalence of hypertension, including regional and national prevalence studies. However, long-term follow-up studies on incidence of hypertension are relatively few and mostly limited to specific ages and regions. This paper summarizes the prevalence, incidence and epidemiological trend of hypertension in Chinese adults. The hypertension prevalence increased from 5.1% in 1959 to 27.5% in 2018, and presents an overall trend of high in the north and low in the south. The hypertension incidence is at a high level (the cumulative incidence was 33.4% after 22 years-follow-up), but there are few researches on the trend of hypertension incidence in huge region.

The detailed knowledge of the morphological structure, drainage pathways and patterns, the first tier lymph node of the cardiac lymphatic and its relationship with the circulatory system has not yet been completed. Although, the cardiac lymphatics had been described with renewed interest in past years, which was attributed to the transparent nature of lymphatic vessels that are difficult to be observed. In this study, cardiac lymphatics of the goat heart were perfused by a direct microinjecting technique with a radiopaque mixture. This demonstrated the subepicardial and subendocardial lymph capillary networks communicating with transmyocardial lymph vessels and then entering to subepicardial collecting lymph vessels that were directed toward the atrio-ventricular sulcus where they form a confluence from which the main cardiac lymph channels. We also found that: 1) the quantity and caliber of collecting lymph vessels varied in each goat heart; 2) drainage patterns of lymph vessels in the goat heart were different in individuals; 3) the first tier lymph node that each major lymph vessel drained to was different; and 4) multiple lymphatic-venous anastomosis sites have been confirmed to exist in the subepicardium of the left and right ventricles of each goat heart, which may be the morphological structure to accelerate the return of intercellular fluid to the venous system during excessive exercise of the heart. Therefore, the information may provide reference for further study in physiological and pathological conditions of the human heart.
