Objective: The association between school bullying and attention deficit hyperactivity disorder (ADHD) symptoms among students in primary schools and the moderating role of gender was explored to provide scientific evidence for the prevention and control of school bullying. Methods: A total of 4 764 students from 2 primary schools in Wuhan were selected using the convenience sampling method in March 2023. The Olweus Bully/Victim Questionnaire and Strengths and Difficulties Questionnaire were used. A Pearson χ 2 test was used to compare differences in school bullying rates among children with and without ADHD symptoms. Pearson correlation analysis and Process 3.3 were used to analyse the association between ADHD symptoms, and school bullying behaviour and the moderating role of gender. Results: The reported rate of bullying victims in primary schools was 24.2% and the rate of bullying perpetration was 3.8%. The rate of ADHD symptom detection among primary school students was 5.9%. ADHD symptoms were positively associated with bullying and bullying victim behaviour ( r =0.16, 0.27, P <0.01). Specifically, the association between ADHD symptoms and bullying behavior tended to be stronger among boys than girls ( β boy =0.17, t =11.13; β girl =0.07, t =4.11, P <0.01). Conclusions ADHD symptoms are an important factor influencing school bullying behaviors in students, and gender moderates the association. In the process of preventing and controlling school bullying, ADHD symptoms and gender differences should be emphasized and comprehensive interventions should be implemented.

BACKGROUND: There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden. METHODS: Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status. RESULTS: A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status. CONCLUSIONS Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.

Objective:To observe the application of the controlled respiratory persistence monitor designed based on the principle of rhythmic temperature variations in artificial airways among different populations and in various artificial airways,and to discuss the feasibility and efficacy of monitoring controlled respiration persistence,and to provide a new method for the clinical respiratory monitoring.Methods:A total of 60 adult patients scheduled for general anesthesia,and 30 pediatric patients aged from 1 to 3 years old,classified as American Society of Anesthesiologists(ASA)Ⅰ-Ⅱ,were selected.A total of 60 adult patients were randomly divided into adult tracheal intubation(ATI)group and adult laryngeal mask(ALM)group,and there were 30 cases in each group.Additionally,30 pediatric patients aged from 1 to 3 years old were regarded as pediatric tracheal intubation(CTI)group.After induction of general anesthesia,the patients in CTI and ATI groups were underwent tracheal intubation,while the patients in ALM group were given a laryngeal mask inserted and were connected to the anesthesia machine for mechanical ventilation.Whether or not the device could detect the respiratory rate(RR)of the patients in various groups was observed;the RR detected by the device and the frequency set on the anesthesia machine in various groups were compared.All the patients in three groups were simulated three common clinical scenarios of continuous respiration changes before surgery:disconnection of the breathing circuit,failure to switch from manual to mechanical control on the anesthesia machine,and slow air leakage in the breathing circuit.The ways to report the alert and start time of the atarm by the monitors were compared.Results:The controlled respiratory persistence monitor was able to detect the RR of the patients in three groups,and there was no significantly difference between the RR detected by the device and the frequency set on the anesthesia machine(P＞0.05).In the simulated scenarios of common respiratory persistence changes,all the patients in three groups received an artificial voice alarm signaling"Attention,breathing has stopped.",which was acknowledged.There was no significant difference in the start time of alarm of the controlled respiratory persistence monitor between ATI group and ALM group(P＞0.05).Compared with the start time of alarm of the patients in the same group across different scenarios,compared with slow air leakage in the breathing circuit,the start time to alarm for circuit disconnection and failure to switch from manual to mechanical control was shorter(P＜0.05).Conclusion:The clinical application of the controlled respiratory persistence monitor device designed based on the principle of detecting rhythmic temperature variations within artificial airways is feasible and effective in different populations and artificial airways.This device offers a new method for monitoring the respiratory continuity and ensuring the respiratory safety during surgery.

Objective:To investigate the status of fear of progression (FoP) in patients with esophageal gastric variceal bleeding (EGVB) due to liver cirrhosis and analyze its influencing factors.Methods:A convenience sampling method was used to select 210 patients with liver cirrhosis and EGVB who were hospitalized at Shanxi Bethune Hospital and Shanxi Provincial People's Hospital between May and December 2023. Data were collected using a general information questionnaire, the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), the Brief Illness Perception Questionnaire (BIPQ), the Medical Coping Modes Questionnaire (MCMQ), and the Perceived Social Support Scale (PSSS) .Results:A total of 210 questionnaires were distributed and 200 valid questionnaires were recovered, with a valid recovery rate of 95.24%. Among 200 EGVB patients, the FoP-Q-SF score was (31.82±10.02). Multiple linear regression analysis showed that gender, number of bleeding episodes, illness perception, coping strategies, and social support were significant influencing factors of FoP in these patients ( P<0.05) . Conclusions:The incidence of FoP is relatively high in patients with liver cirrhosis and EGVB. Healthcare providers should pay attention to the impact of gender, bleeding episodes, illness perception, coping strategies, and social support on FoP and implement targeted interventions to reduce its levels.

Objective:To analyze the drug-resistant gene loci of Mycoplasma pneumoniae (MP) using metagenomic next-generation sequencing (mNGS). Methods:From November 2022 to October 2023, 697 clinical samples (including sputum, alveolar lavage fluid and blood) of 686 children with Mycoplasma pneumoniae positive detected by mNGS were retrospectively analyzed. Samples were divided into intensive care unit (ICU) group and non-ICU group, Chi-square test was used to compare groups, and Mann-Kendall trend test was used to analyze the change trend of the detection rate of drug resistance gene loci over time. Results:Of the 697 samples, 164 were from the ICU group and 533 were from the non-ICU group. The detection rate of Mycoplasma pneumoniae resistance gene was 44.3% (309/697), and all detected drug-resistant gene loci of MP were A2063G. The detection rate of Mycoplasma pneumoniae in ICU group was 50.0% (82/164), and the detection rates of Mycoplasma pneumoniae resistance gene loci in sputum, alveolus lavage fluid and blood samples were 75.0% (18/24) and 48.4% (62/128), respectively. The detection rate in sputum was higher than alveolus lavage fluid samples ( χ2=5.72, P=0.017). The detection rate of Mycoplasma pneumoniae in non-ICU group was 42.6% (227/533), the detection rate of Mycoplasma pneumoniae resistance gene loci in sputum and alveolar lavage fluid was 40.0% (16/40), 44.3% (201/454), and no detection rate in blood samples (0/12). There was no significant difference in the detection rate of alveolar lavage fluid and sputum ( χ2=0.27, P=0.602). From November 2022 to October 2023, the detection rate of submitted samples showed an increasing trend month by month (overall: Z=3.99, ICU inspection group: Z=2.93, non-ICU group: Z=3.01, all P<0.01). Among the bacteria commonly detected with Mycoplasma pneumoniae, Streptococcus pneumoniae accounted for the highest proportion, the detection rate was 15.5% (108/697), and Epstein-Barr virus accounted for the highest proportion of 17.6% (123/697). Conclusions:From November 2022 to October 2023, the detection rate of Mycoplasma pneumoniae drug resistance gene loci showed an increasing trend. The detection rate of drug resistance gene loci in sputum samples of ICU group was higher than alveolus lavage fluid. No new drug resistance site were detected.

OBJECTIVE: To explore the clinical characteristics and genetic basis for a child with X-linked lissencephaly with abnormal genitalia (XLAG). METHODS: A child with XLAG who had presented at the Third Affiliated Hospital of Zhengzhou University in May 2021 was selected as the study subject. Peripheral blood samples of the child and his parents were collected and subjected to high-throughput sequencing. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the result was analyzed by using bioinformatic software. RESULTS: The child was found to have harbored a hemizygous c.945_948del variant in exon 2 of the ARX gene, which as a frameshifting variant has resulted in a truncated protein. His mother was found to be heterozygous for the variant, whilst his father was of wild type. The variant was unreported previously. CONCLUSION The hemizygous c.945_948del variant of the ARX gene probably underlay the XLAG in this patient. Above finding has provided a basis for the diagnosis and genetic counseling for this family.

Objective:To explore the potential molecular targets and mechanism of Zeqi Decoction in the treatment of lung adenocarcinoma (LUAD) through bioinformatics and cell experiment.Methods:The active components of Zeqi Decoction were collected based on TCMSP database and literature search. Then R software was used to screen differentially expressed genes in LUAD from TCGA and GEO databases. The co-expression module was obtained through weighted gene co-expression network analysis (WGCNA), and the potential targets were obtained after matching and mapping with targets of Zeqi Decoction. Enrichment analysis of GO function and KEGG pathway of targets was conducted. The results were experimentally verified. The lung adenocarcinoma cell lines A549 and H1299 were divided into blank control group and Zeqi Decoction group according to random number table. The inhibition rate of cell proliferation was detected by cell proliferation test (CCK-8); the expression of leukocyte differentiation antigen 36 (CD36) in A549 and H1299 cells was detected by Western blot; the levels of low density lipoprotein receptor (LDLR) and IL-6 were detected by ELISA.Results:Totally 157 anti-lung adenocarcinoma active components and 18 potential targets were obtained, mainly including CD36, IL6, LDLR, etc. The main target of Zeqi Decoction in the treatment of lung adenocarcinoma was lipid metabolism. The results showed that Zeqi Decoction could effectively inhibit the activity of A549 and H1299 cells and the levels of CD36, LDLR and IL-6.Conclusion:Zeqi Decoction can inhibit the inflammatory response by down-regulating the protein expressions of CD36 and LDLR, thereby slowing the proliferation of cells.

Objective:To study the clinical characteristics and risk factors of intrauterine Ureaplasma urealyticum (UU) infection in very low birth weight preterm infants.Methods:From March 2019 to February 2022, very low birth weight preterm infants with gestational age 28~32 weeks admitted to our hospital were enrolled in this single-center retrospective study. According to the UU test results of respiratory tract samples obtained within 24 h after admission, the infants were assigned into the UU group (UU-PCR positive) and the non-UU group (UU-PCR negative). SPSS 26.0 statistical software was used to compare the clinical characteristics, laboratory indices, and complications between the two groups. Risk factors of UU infection were calculated.Results:A total of 327 preterm infants were included: 45 in the UU group and 282 in the non-UU group. No significant differences existed in gender, gestational age, birth weight and delivery pattern between the two groups ( P>0.05). Compared with the non-UU group, the UU group had significantly higher incidences of premature rupture of membranes (PROM) and chorioamnionitis, elevated white blood cell and platelet counts, procalcitonin and C-reactive protein levels, total duration of oxygen use and ventilation, bronchopulmonary dysplasia, necrotizing enterocolitis and metabolic osteopathy ( P<0.05). Multivariate logistic regression analysis showed that PROM ( OR=5.444, 95% CI 2.749-10.781, P<0.001) and chorioamnionitis ( OR=2.161, 95% CI 1.048-4.454, P=0.037) were independent risk factors for UU infection. Conclusions:PROM and chorioamnionitis are risk factors for UU infection in very low birth weight preterm infants. For high-risk premature infants, the UU test should be completed as soon as possible after birth.

Objective:To detect the characteristics of bacteria in the feces of patients with rheumatoid arthritis (RA) and to further discover the relationship between intestinal flora and the status of peripheral cytokine, which might be able to provide new ideas for clinical treatment.Methods:The bacterial diversity and abundance of 111 RA patients and 100 age-and gender-matched healthy controls (HC) were detected by 16S high-throughput sequencing platform and compared. Based on the 16S rDNA high-throughput sequencing platform, the 16S rDNA V3 region in the participants' fecal specimens were analyzed and compared to screen for different bacterial groups. Alpha diversity was analyzed by the mothur software and the screening for different flora was tested by using Mann-Whitney, and the relationship between intestinal flora and peripheral cytokines were analyzed, too.Results:There was no significant difference in gender ( χ2=0.005, P=0.947) and age ( t=0.728, P=0.467) between the two groups. Patients with RA had a lower chao1 index ( Z=-2.188, P=0.029) and ACE index ( Z=-2.078, P=0.038) of species richness, and the Shannon index ( Z=-2.064, P=0.039) and Simpion index ( Z=-2.064, P=0.039) of diversity index in the feces compared with those of HC. At the genus level, the relative abundance of Bifidobacterium ( Z=-2.388, P=0.017), Lactobacillus ( Z=-2.543, P=0.011), Clostridium sensu stricto ( Z=-3.842, P<0.01), Blautia ( Z=-2.064, P=0.039) , Clostridium Ⅺ ( Z=-2.682, P<0.01), Turicibacter ( Z=-2.437, P=0.015), Phascolarctobacterium ( Z=-3.524, P<0.01), Megasphaera ( Z=-2.87, P<0.01), Veillonella ( Z=-2.472, P=0.013), Citrobacter ( Z=-3.263, P<0.01) and Escherichia/Shigella ( Z=-4.265, P<0.01) in RA were significantly higher than those of HC ( P<0.05), Butyricimonas ( Z=-3.071, P=0.002), Odorbacter ( Z=-2.257, P=0.024), Blautia ( Z=-2.064, P=0.039), Clostridium_ⅩⅣb ( Z=-2.901, P<0.01), Lachnospiracea_incertae sedis ( Z=-2.159, P=0.031), Acetivibrio ( Z=-2.995, P<0.01), Butyricicoccus ( Z=-2.162, P=0.031) and Gemmiger ( Z=-2.949, P<0.01) relative abundance were significantly decreased in RA patients ( P<0.05). LEfSe analysis showed γ-proteobacteria and Lachnospiraceaehad the most significant difference between the two groups. Further, patients with high inflammatory cytokines such as IL-17 and TNF-α hada higher relative abundance of Prevotella. Conclusion:The diversity and abundance of intestinal flora in RA patients are significantly different from those of healthy population, which is closely related to the levels of inflammatory cytokines, suggesting imbalance of intestinal flora might be involved in the occurrence and development of RA.

Objective: To explore the effect of early pulmonary rehabilitation on stroke associated pneumonia by the ICU specialist nurses. Methods: Totally 40 cases of stroke patients from January 2017 to June 2017 were selected into the control group, and 44 cases of stroke patients from July 2017 to December 2017 were set as the intervention group. The patients in the control group were given routine care, and those in the experimental group were given early pulmonary rehabilitation in addition to routine care by ICU specialist nurses. The clinical outcome such as the occurrence of SAP, the length of intensive care units (ICU) stay and the duration of mechanical ventilation were compared. Results: The incidence of SAP in the intervention group was 13.64%(6/44), significantly lower than that 32.50(13/40) in the control group (χ²=4.26, P<0. 05), and the length of ICU stay the duration of mechanical ventilation were (5.59±3.93), (3.2±0.84)days, which were lower than (8.50±7.89), ((13.13±9.58)days in the control group (t=2.106,2.678, P<0.05) , the prealbumin levels was (219.43±59.71) mg/L,higher than (192.20±54.85) mg/L in the control group (t=-2.170, P<0.05) , the difference was statistically significant. Conclusion Early pulmonary rehabilitation can effectively reduce the incidence of SAP and better clinical outcome. And we also should improve the SAP risk assessment and the management of swallowing and nutrition.
