Objective:To investigate the correlation between subjective hearing impairment and cognitive function in the elderly in the community of Changzhou City.Methods:This study was a retrospective cohort study. A total of 1 132 elderly people recruited from 4 communities in Changzhou City from August to October in 2023 were selected as the research objects. The social demographic and cognitive function were collected, cognitive function was assessed using the mini-mental state examination (MMSE), while the connected test, replica cube, and clock draw in the Montreal cognitive assessment (MoCA) were selected to assess visuospatial and executive function. The subjects were divided into the no-hearing impairment group (726 subjects) and hearing impairment group (406 subjects) according to the self-reported hearing impairment of the elderly. The basic data of the two groups and the differences in different cognitive domains were analyzed, and the correlation between subjective hearing impairment and cognitive function of the elderly in the community was analyzed by univariate and multivariate logistic regression analysis.Results:The incidence of cognitive impairment in the hearing impairment group was significantly higher than that in the no-hearing impairment group (20.2% vs 6.6%), the scores of location orientation, memory, attention and calculation, recall, language ability, clock draw, and the total score of MMSE, visuospatial and executive function in the hearing impairment group were all significantly lower than those in the normal hearing group [(4.76±0.78) vs (4.91±0.45) points, (2.79±0.59) vs (2.90±0.36) points, 4 (3, 5) vs 5 (4, 5) points, 2 (1, 3) vs 2 (2, 3) points, 8 (7, 9) vs 9 (8, 9) points, 2 (2, 3) vs 3 (2, 3) points, 27 (24, 29) vs 27 (26, 29) points, 3 (2, 3) vs 3 (2, 4) points] (all P<0.05). There was a positive correlation between subjective hearing impairment and cognitive function impairment in community-dwelling elderly ( OR=3.544, 95% CI: 2.410-5.213) ( P<0.001). Conclusion:The incidence of cognitive impairment is higher in the community-dwelling elderly with subjective hearing impairment, and hearing impairment is a positive correlation factor of cognitive impairment.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Aim To explore the effect of berberine (B E) on RSV infected HEp-2 cells and the related mechanism. Methods HEp-2 cells were infected with RSV and treated with BE. Cell viability was assessed using the CCK-8 assay. Protein expression levels of NLRP3, ASC, caspase-1, PINK1, Parkin, Beclinl, p62, LC3 I,LC3 II,and BNIP3 in HEp-2 cells were detected by Western blot. The secretion level of IL-1 p in HEp-2 cells was measured using ELISA. Apoptosis rate and mitochondrial membrane potential of HEp-2 cells were examined by flow cytometry. Mitochondrial ROS (mtROS) in HEp-2 cells was detected through MitoSOX staining. Colocalization of mitochondria and autophagosomes in HEp-2 cells was investigated using immunofluorescence staining. Cyclosporin A was used for validation experiments. Results BE could significantly improve the activity of RSV-infected HEp-2 cells,reduce the apoptosis rate (P < 0. 05), and decrease the activation level of NLRP3 inflammasomes and IL-lp level (P <0. 05); BE improved mitochondrial function by increasing mitochondrial membrane potential and ATP levels,and reduced mtROS. BE significantly promoted the colocalization of mitochondria-autophagosome in RSV infected cells, inducing PINK1/ Parkin and BNIP3 to mediate mitochondrial autophagy; cyclosporine A aggravated RSV infection. Conclusions BE has protective effects on HEp-2 cells infected by RSV. The mechanism may be related to the inhibitory effect of BE on the production of mtROS and the activation of NLRP3 inflammasomes by inducing PINK1/ Parkin and BNIP3-mediated mitochondrial autophagy.

Method To construct an EndMT cell model, PMVEC was treated with TGF-β1 (5 μg · L

The assessment of adverse drug events is an important basis for clinical safety evaluation and post-marketing risk control of drugs,and its causality assessment is gaining increasing attention.The existing methods for assessing the causal relationship between drugs and the occurrence of adverse reactions can be broadly classified into three categories:global introspective methods,standardized methods,and probabilistic methods.At present,there is no systematic introduction of the operational details of the various methods in the domestic literature.This paper compares representative causality assessment methods in terms of definition and concept,methodological steps,industry evaluation and advantages and disadvantages,clarifies the basic process of determining the causality of adverse drug reactions,and discusses how to further improve the adverse drug reaction monitoring and evaluation system,with a view to providing a reference for drug development and pharmacovigilance work in China.

Objective To investigate the clinical efficacy of transjugular intrahepatic portosystemic shunt(TIPS)combined with indwelling catheter-directed thrombolysis for the treatment of portal vein thrombosis(PVT).Methods The clinical efficacy of 307 patients with portal hypertension complicated by PVT,who received successful TIPS combined with indwelling catheter-directed thrombolysis at the Affiliated Beijing Shijitan Hospital of Capital Medical University of China between January 2016 and December 2019,were retrospectively analyzed.Before and after TIPS,the inferior vena cava pressure(IVCP)and portal vein pressure(PVP)were measured,and the pre-TIPS,post-TIPS(before thrombolysis),and post-thrombolysis portal pressure gradient(PPG,PPG=PVP-IVCP)was separately calculated.Reexamination of portal venography DSA was performed to determine the degree of PVT disappearance and whether the shunt was unobstructed.All patients were followed up for one year.Results The pre-TIPS,post-TIPS(before thrombolysis),and post-thrombolysis mean PPG was(24.50±6.91)mmHg,(18.51±5.11)mmHg,and(10.17±3.97)mmHg,respectively.The post-thrombolysis mean PPG was strikingly lower than the pre-thrombolysis values,the differences were statistically significant(P＜0.001).Among the 307 patients,complete disappearance of PVT was observed in 221(72.3%),remarkable reduction of PVT in 86(27.7%),and no invalid result was seen.The patients having complete patency of the shunt flow accounted for 85.7%of the 307 patients(261/307),and the patients having partial patency of the shunt flow accounted for 14.3%of the 307 patients(46/307).Forty-two patients developed complications,and no death occurred.All patients were followed up for one year,and the main clinical symptoms were improved or completely disappeared.Among the 307 patients,an increase in thrombus volume was found in 17(5.5%)when compared to their postoperative values,which returned to the first-time postoperative level after local treatment of the thrombus via the TIPS shunt combined with catheter-directed thrombolysis.Within one year after TIPS and thrombolysis,overt hepatic encephalopathy(OHE)occurred in 54 patients(17.6%,54/307).One patient died of hepatic failure 9 months after TIPS,another patient died of cerebral hemorrhage 11 months after TIPS,and all the remaining patients were alive.Conclusion For patients with portal hypertension complicated by PVT,TIPS combined with indwelling catheter-directed thrombolysis is clinically safe and effective.The standardized,systematic management of the whole therapeutic process should be strengthened.(J Intervent Radiol,2024,32:22-27)

Objective To investigate the expression significance and prognostic value of long non-coding RNA tumor susceptibility candidate gene 9(lncRNA CASC9)and YKT6 in oral squamous cell carcinoma(OSCC).Methods A total of 110 patients with OSCC treated in the Affiliated Hospital of Shaanxi University of Traditional Chinese Medicine from January 2016 to January 2018 were selected as the study objects.The mRNA expression of lncRNA CASC9 and YKT6 in OSCC cancer tissue and adjacent tissues was detected by real-time fluorescence quantitative PCR.Immunohistochemistry was used to detect YKT6 protein expression in OSCC cancer tissue and adjacent tissues.Kaplan-Meier curves were used to analyze the influence of different lncRNA CASC9 and YKT6 mRNA expression on the prognosis of OSCC patients.Cox regression model was used to analyze the prognostic factors of OSCC.Results The lncRNA CASC9 and YKT6 mRNA expression in OSCC cancer tissues were 3.12±0.57 and 2.69±0.42,respectively,which were significantly higher than those in adjacent tissues(1.02±0.25,1.13±0.21),and the differences were statistically significant(t=35.386,34.843,P＜0.05).The positive rate of YKT6 protein in OSCC cancer tissues was 81.82％(90/110),which was higher than that in adjacent tissues[9.09％(10/110)],and the difference was statistically signifi-cant(x2=117.333,P＜0.05).There was a positive correlation between lncRNA CASC9 mRNA expression and YKT6 mRNA expression in OSCC cancer tissues(r=0.788,P＜0.001).The lncRNA CASC9 and YKT6 mRNA expressions in cancer tissues of OSCC with TNM stages m to Ⅳ,low differentiation and lymph node metastasis were higher than those in cancer tissues of OSCC with TNM stages Ⅰ to Ⅱ,high school differenti-ation and no lymph node metastasis,the difference was statistically significant(all P＜0.05).The 5-year cu-mulative survival rate of lncRNA CASC9 high expression group and YKT6 mRNA high expression group was lower than that of lncRNA CASC9 low expression group and YKT6 mRNA low expression group,and the difference was statistically significant(Log-rank X2=7.080,8.741,P=0.008,0.003).High expression of ln-cRNA CASC9,high expression of YKT6 mRNA,TNM stage m to Ⅳ,low differentiation and lymph node me-tastasis were prognostic risk factors in OSCC patients.Conclusion The expression of lncRNA CASC9 and YKT6 in OSCC cancer tissue is elevated,which can be used as tumor markers to evaluate the prognosis of OS-CC patients.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34⁺⁰ weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

Objective: To investigate the clinical features and gene variation characteristics of children with dynein cytoplasmic 1 heavy chain 1 (DYNC1H1) gene associated spinal muscular atrophy with lower extremity predominant (SMALED) 1. Methods: The clinical data of 4 SMALED1 children admitted to Peking University First Hospital from December 2018 to May 2021, who were found to have pathogenic variation of DYNC1H1 gene through genetic testing, except for other genes known to be related to motor retardation, were retrospectively summarized to analyze the phenotype and genotype characteristics. Results: There were 3 males and 1 female. The age of onset was 1 year, 1 day, 1 day and 4 months, respectively. The age of diagnosis was 4 years and 10 months, 9 months, 5 years and 9 months, and 3 years and 1 month, respectively. The clinical manifestations were muscle weakness and muscular atrophy of lower limbs, 2 cases with foot deformity, 1 case with early non progressive joint contracture, 1 case with hip dislocation and 1 case with mental retardation. De novo heterozygous missense variations in DYNC1H1 gene were found in all 4 children. According to the rating of American College of medical genetics and genomics, they were all possible pathogenic and pathogenic variations, with p.R598C, p.P776L, p.Y1109D variations had been reported, and p.I1086R variation had not been reported. Conclusions: For those with unexplained lower limb muscle weakness, muscle atrophy, joint contracture and foot deformity, upper limb motor ability related retention, with or without mental retardation, as well as the motor ability progresses slowly, it is necessary to consider the possibility of SMALED1 and the detection of DYNC1H1 gene when necessary.
