BackgroundPersistent cognitive impairment is prevalent among patients with stable schizophrenia. While serum total bile acid （TBA） level in acute-phase patients are known to be associated with cognitive dysfunction， the relationship between serum TBA and multi-dimensional cognitive functions in stable phase patients remains unclear. ObjectiveTo investigate the correlation between serum TBA level and cognitive function in patients with stable schizophrenia， and to evaluate its predictive value for cognitive impairment， thereby providing a serological biomarker for the timely identification and objective assessment of cognitive dysfunction. MethodsA cross-sectional study was conducted on 137 inpatients with stable schizophrenia at The Fourth People's Hospital of Yancheng from March to December 2024. All participants met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）. Cognitive function was evaluated using the Chinese Brief Cognitive Test （C-BCT）， patients were categorized into four groups： normal cognition （n=28）， mild impairment （n=28）， moderate impairment （n=47）， and severe impairment （n=34）. Fasting venous blood samples were collected， and serum TBA level was quantified using an enzymatic cycle assay. Spearman correlation analysis was ultilized to determine the relationship between serum TBA level， overall cognitive function， and specific cognitive domains. Binary Logistic regression model was used （adjusting for covariates such as age， gender， and disease duration） to analyze the impact of serum TBA level on overall and individual cognitive functions. The predictive value of serum TBA level for overall cognitive impairment was evaluated using receiver operating characteristic （ROC） curve. ResultsSerum TBA levels differed significantly among the four groups （H=18.677， P<0.01）. Specifically， serum TBA levels in both the moderate and severe cognitive impairment groups were significantly higher than those in the normal cognitive group （adjusted P<0.01）. Serum TBA level was positively correlated with the severity grading of overall cognitive impairment （r_s=0.354， P<0.05）， and negatively correlated with T-scores on the trail making test （r_s=-0.328， P<0.05）， continuous performance test （r_s=-0.247， P<0.05）， digit span （r_s=-0.265， P<0.05）， and symbol coding （r_s=-0.221， P<0.05）. Binary Logistic regression analysis identified serum TBA level as an independent risk factor for overall cognitive impairment （OR=1.322， 95% CI： 1.021 - 1.713， P=0.034）， with a particularly robust predictive ability for impaired information processing speed （OR=1.325， 95% CI： 1.057 - 1.661， P=0.015）. The area under ROC curve （AUC） for serum TBA level in predicting overall cognitive impairment was 0.738， with a sensitivity of 60.61% and a specificity of 78.64%. ConclusionIn patients with stable schizophrenia， elevated serum TBA levels are associated with worse overall cognitive function， as well as deficits in information processing speed， attention， working memory， and executive function. Serum TBA serves as an independent risk factor and exhibits moderate predictive value for overall cognitive impairmen，particularly in the domain of information processing speed. ［Funded by Yancheng Municipal Health Commission Medical Research Project （number， YK2024141）］

Objective To analyze the disease burden and trends of bladder cancer in China and globally from 1992 to 2021.  Methods Using the GBD 2021 database, the incidence, prevalence, mortality, and disability-adjusted life years (DALYs) rates of bladder cancer in China and globally from 1992–2021 were analyzed. Average annual percentage change (AAPC) was calculated using Joinpoint regression. Subgroup analyses by sex and age were conducted, and a Bayesian age-period-cohort (BAPC) model was used to predict trends in age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) for the next 15 years.  Results In 2021, China reported 106 000 new cases (ASIR: 5.14/100 000), 571 000 prevalent cases (age-standardized prevalence rate, ASPR: 26.61/100 000), 43 000 deaths (ASMR: 2.34/100 000), and a DALY rate of 45.31/100 000. From 1992–2021, China showed upward trends in ASIR and ASPR but declines in ASMR and DALYs, while global ASIR, ASMR, and DALYs decreased overall with slow ASPR growth. The peak cases in China and globally were both concentrated in the 65-79 age group, with a significantly higher burden on males than females. In China, smoking-related ASMR and ASDR exceeded global averages and rose, whereas high glucose-related indexes were lower and declined. Projections for 2021–2036 indicated that the global incidence and mortality rates would be rising, but ASIR/ASPR would be declining, while in China, the incidence rate would continue to rise, and the mortality rate will stabilize, with a significant increase in ASIR and a gradual decrease in ASPR.  Conclusion From 1992 to 2021, the incidence of bladder cancer in China has shown a continuous upward trend and is projected to persist in the future, with significant gender and age differences. Particular attention should be given to elderly males aged 85-89. The disease burden of bladder cancer attributable to smoking continues to rise, highlighting the urgent need to strengthen tobacco control policies.

Objective: To analyze the frequency and investigate the causes of unexpected antibodies in D-negative blood donors. Methods: From January 2022 to December 2024, 3 768 D-negative blood donors sent to our laboratory were selected as research subjects. D-negative confirmation test and RhCE phenotype detection were applied by saline tube method and microcolumn gel indirect antiglobulin test (IAT), respectively. Antibody screening and identification were performed using the polybrene method and IAT column agglutination methods. Anti-D, anti-C and anti-G specificities were identified by a two-step adsorption-elution method, and the genotypes of D-negative samples were determined by RHD gene amplification, Sanger sequencing, and PacBio Single Molecule Real-Time (SMRT) sequencing. Results: Among D-negative donors, ccee and Ccee phenotypes accounted for the highest proportion, 55.68% (2 098/3 768) and 29.56% (1 114/3 768), respectively, while CcEE and CCEe phenotypes were the least, with one case detected in each, accounting for 0.03% (1/3 768). A total of 165 cases with D variant phenotype were detected, and the proportion of D variant was 4.38% (165/3 768) in the donors detected by D-negative confirmation test. Antibody screening positive blood donors were identified in 93 cases with a proportion of 2.47% (93/3 768). Antibody specificity was determined in 84 blood donors, and 9 samples showed no clear specificity. Anti-D was detected most frequently (n=68), in which 6 of them were detected having multiple antibodies, anti-D + anti-C (n=2), anti-D + anti-G(n=1), and anti-D + anti-E(n=3). The other antibodies detected were anti-E (n=1), anti-M(n=9), anti-P1 (n=3), anti-Le (n=1), and anti-HI(n=2). Fourteen cases were detected with anti-D in serological D-negative donors with C+ or E+ phenotype, in which three of them were DVI type 3 individuals and 11 cases were D negative individuals. Conclusion: The incidence of unexpected antibodies was higher in D-negative blood donors than in the total donors, with anti-D being the most common. The data provide insights for prevention and monitoring hemolytic disease of the fetus and newborn (HDFN) caused by anti-D. To ensure the safety of blood transfusion, routine unexpected antibody screening for RhD-negative blood donors is recommended to prevent the use of unexpected antibodies positive plasma in the clinic.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.

Objective: To explore the association between sleep quality and cardiorespiratory fitness among secondary school students, so as to provide a reference for promoting the overall development of physical and mental health of Chinese adolescents. Methods: From September to December 2023, 5 713 secondary school students aged 13 to 18 years were selected by the stratified cluster random sampling method from Shanghai, Suzhou, Taiyuan, Wuyuan, Xingyi, and Urumqi, respectively. Sleep quality and cardiorespiratory fitness level of secondary school students were evaluated by Pittsburgh Sleep Quality Index(PSQI) combined with cardiorespiratory fitness test, and the association between sleep quality and cardiorespiratory fitness was analyzed by Pearson s correlation and multivariate linear regression. Results: The report rate of poor sleep quality among secondary school students was 33.7 %(1 926/5 713). The PSQI scores of girls aged 13-18 years were higher than those of boys ( χ 2=1.60, 12.78, 15.62, 3.04, 10.09, 13.65 ) ( P <0.05). The 20 m SRT of secondary school students was 40 (27，51) times, and the VO 2max was 46.27 (40. 84 ，51.30) mL/(kg min). The 20 m SRT and VO 2max of girls of all ages were lower than those of boys( Z =-15.27 to -6.41 , -18.06 to -14.07, P <0.05). Cardiorespiratory fitness (VO 2max) was negatively correlated with sleep duration and hypnotic medication scores in boys ( r =-0.032, -0.005); VO 2max was negatively correlated with sleep duration and daytime dysfunction scores in girls ( r =-0.028, -0.008) ( P <0.05). After controlling the related variables, linear regression analysis showed that the total PSQI score was negatively correlated with VO 2max among secondary school students( β =-0.347, P <0.01). Conclusions Secondary school students with better sleep quality have higher levels of cardiorespiratory fitness. Sleep quality should be promoted to improve cardiorespiratory fitness levels in secondary school students.

Under the multi-campus development model of public hospitals,cultural integration and innovation face nu-merous challenges due to spatial constraints,personnel structure differences,and functional positioning across campuses.System-atic cultural development is required to bridge these gaps and enhance the sense of belonging among both patients and staff in new campuses.This case study focuses on the Huangpu Campus of Sun Yat-sen University Cancer Center,launched in 2021,explo-ring a dual-dimensional approach to multi-campus cultural integration through"healing spaces."The practical strategies include:①Direct Space Construction:Establishing patient-centered healing environments through service hubs to optimize clinical experi-ences and humanistic care;(②Inidirect Environment Development:Leveraging staff service centers to foster the integration of the hospital's"collaborative,fulfilling,and striving culture,"thereby strengthening employee engagement.Post-implementation,significant improvements were observed in both patient and staff satisfaction metrics.The initiative has yielded a replicable cultur-al management framework for multi-campus public hospitals,offering valuable insights for cultural innovation in similar healthcare settings.

In order to investigate the related pathogens and reveal the etiological characteristics of gout in goslings,191 typical clinical cases from partial regions of China were examined by RT-PCR/PCR detection of viral nucleic acids in domestic poultry and pathological analysis.The autop-sy results show that the clinical cases could be classified into three types based on the severity of urate deposition:severe,moderate,and mild,namely systemic urate deposition,local urate deposi-tion mainly in the liver and kidneys,and only a small amount of fine-grained urate deposition in the liver,gallbladder,or glandular stomach.The results of RT-PCR/PCR detection showed that the to-tal positive rates were as follows:GAstV Group2 63.9％,GAstV Group1 50.3％,AAstV-2 38.7％,novel Muscovy duck parvovirus(NPV)17.8％,GPV 16.2％,GoCV 12.6％,MDPV 7.9％,MDRV 8.4％,DPV 0.5％,GPMV and NDV 0.5％,the AstV-1、ARV、TMUV、NDV、FAdV、GHPyV were zero.Among all the postive samples,the rates of single positive,double positive,and multiple posi-tive were 18.3％,27.2％,and 44.0％,respectively.The rate of single positive samples containing AAstV was only 12.0％,the double or multiple positive samples containing GAstV Group 1/2 was 60.7％,and the rate of samples without GAstV Group 1/2 was 10.5％.The results also showed that 20(10.5％)samples were negative for 16 types of viruses.The AAstV particles isolated from single positive samples appear spherical shape,non-enveloped and 20-80 nm minsize.Two types of virus particles which with spherical shape and diameters of 40-100 and 20-40 nm can be isolated from the negative samples.The virus inoculation results show that the goose embryos can be led to death by clinical GAstV isolates,which with classic histopathological characteristics.Although the GAstV isolates cannot led to death and obvious typical histopathological change in goslings,the vi-ral nucleic acids can be detected in heart,liver,spleen,kidney,intestine and cloacal anal swabs.The above results indicated that there were multiple pathogens co-infection dominated by AAstv in Gosling gout in China,including cross species infections of multiple AAstVs,parvovirus,ARV and suspec-ted novel viruses.Moreover,the GAstV maybe not the only pathogen causing gout in goslings.

Schizophrenia is a common, severe, and complex psychiatric disorder worldwide. Genetic factors account for around 80% of the etiology of schizophrenia, yet objective diagnostic biomarkers remain lacking. This article reports two cases of female monozygotic twins diagnosed with schizophrenia, exhibiting a balanced translocation between 22q11.2 and 4p15.3. Reviewing the literature, we analyze and discuss the correlation between chromosomal balanced translocation regions and the pathogenesis of mental disorders. This aims to encourage psychiatrists to consider new perspectives on the diagnosis of schizophrenia.

Objective:To observe the effect of electroacupuncture at the Shuigou point on systolic phenotype-related factors and on the JAK1/STAT3 signaling pathway of the middle cerebral artery smooth muscle cells in rats modeling cerebral infarction; and to explore the molecular mechanism of treating cerebral infarction with electroacupuncture.Methods:A total of 108 healthy male Wistar rats were randomly divided into a blank group ( n=6), a sham operation group ( n=6), a model group ( n=48) and an electroacupuncture group ( n=48). The model and electroacupuncture groups were randomly divided into eight phase subgroups at 1h, 3h, 6h, 12h, 24h, 72h, 7d and 14d after the modeling of middle cerebral artery occlusion (MCAO), with six rats in each group. The electroacupuncture groups received electric acupuncture at the Shuigou acupoint for 20min after successful modeling. Neurological Severity scoring (NSS) was used to evaluate the neurological impairment. PLN protein expression in the middle cerebral artery and the expression of JAK1 and STAT3 proteins in the rats′ brain tissue were detected using western blotting. PDGF-AA content in the middle cerebral artery was measured using enzyme-linked immunosorbent assays. Results:Compared with the blank and sham operation groups, the average NSS score and PDGF-AA protein expression had increased significantly in the model and electroacupuncture groups. PLN protein expression had decreased significantly at 12h-14d in the model group, but decreased significantly at 12h-7d in the electroacupuncture group. Compared with those two groups, there was a significant increase in JAK1 protein expression at 1h-72h, 3h-6h, 24h-72h, and14d in the model group. In the electroacupuncture group the corresponding significant increases were over 1h-14d, 1h-6h, 24h, 72h, and 14d. STAT3 protein expression had increased significantly in the model group over 6h-14d and 3h-14d. In the electroacupuncture group those increases were over 6h-14d. Compared to the model group, a significant increase was observed in the expression of PLN protein at 14d, with a significant decrease in NSS at 72h, 7d and 14d. PDGF-AA protein had increased significantly at 6h-7d. For JAK1 protein that was at 12h and 14d, and for STAT3 protein it was over 12h-72h and at 14d.Conclusion:Electroacupuncture at the Shuigou point may regulate the expression of PDGF-AA and the JAK/STAT signaling pathway so as to regulate the normal expression of PLN, and thus smooth muscle contraction to maintain the normal functioning of the middle cerebral artery. This may be one of the molecular mechanisms by which electroacupuncture at the Shuohui point improves nerve functioning in treating cerebral infarction.

Objective To investigate the potential categories of nutrition literacy in young and middle-aged patients with type 2 diabetes mellitus combined with overweight or obesity,and analyze the relationship between various latent categories and dietary motivation,so as to provide references for clinical working staff to develop relevant dietary intervention strategies.Methods A convenient sampling method was used to enroll 270 young and middle-aged patients with type 2 diabetes mellitus combined with overweight or obesity from the endocrine department of a tertiary general hospital in Zhenjiang City,Jiangsu province,using basic information questionnaire,Nutrition Literacy Measurement Scale for Chinese adults,and the Regulation of Eating Behaviors Scale to collect data,using latent profile analysis to extract nutrition literacy potential categories,with general data and potential categories as independent variables,dietary motivation as the dependent variable for univariate analysis and multiple linear regression analysis.Results A total of 262 young and middle-aged patients with type 2 diabetes mellitus combined with overweight or obesity completed the survey,and their nutrition literacy could be divided into 3 potential categories:low nutrition literacy group(16.41％),transformation dilemma group(54.96％),and middle and high nutrition literacy group(28.63％).The results of multiple linear regression analysis showed that residency style,potential categories of nutrition literacy and presence of diabetic complications were the influencing factors of dietary motivation in young and middle-aged patients with type 2 diabetes mellitus combined with overweight or obesity(P＜0.05).Conclusion There was a group heterogeneity in nutrition literacy in young and middle-aged patients with type 2 diabetes mellitus combined with overweight or obesity.Clinical working staff should provide targeted interventions based on the patient's potential categories of nutrition literacy to stimulate ongoing motivation to maintain a healthy diet.
