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 (rs=0.354, P<0.05), and negatively correlated with T-scores on the trail making test (rs=-0.328, P<0.05), continuous performance test (rs=-0.247, P<0.05), digit span (rs=-0.265, P<0.05), and symbol coding (rs=-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.

ObjectiveTo investigate the effects of jujuboside A (JuA) on the learning and memory abilities and histopathological changes in the rat model of vascular cognitive impairment (VCI) and explore the potential mechanisms by which JuA treats VCI. MethodsA total of 50 male SPF-grade SD rats were randomized into a sham operation group (n=10), a blank control group (n=10), and a modeling group (n=30). The rats in the modeling group underwent bilateral carotid artery ligation (2-VO) for the modeling of VCI. After stabilization, the VCI rats were randomized into model, JuA (20 mg·kg-¹), and donepezil (0.45 mg·kg-¹) groups. After 4 weeks of gavage, the novel object recognition and Morris water maze tests were conducted to evaluate the learning and memory abilities of rats. Nissl staining was employed to evaluate the morphology and number of hippocampal neurons. Real-time PCR was employed to measure the mRNA levels of glycogen synthase kinase-3β (GSK-3β), cAMP response element-binding protein (CREB), B cell lymphoma-2 (Bcl-2), phosphatidylinositol 3-kinase (PI3K), and protein kinase B (Akt) in the hippocampal tissue. Western blot was employed to quantify the protein levels of GSK-3β, p-GSK-3β, p-CREB, Bcl-2, PI3K, p-PI3K, Akt, and p-Akt in the hippocampal tissue. ResultCompared with the sham operation group, the model group exhibited declines in the learning and memory abilities (P<0.01), neuronal damage and decreased neurons in the hippocampal CA1 region (P<0.01), up-regulation in the mRNA level of GSK-3β (P<0.01), and down-regulation in the mRNA levels of PI3K, Akt, CREB, and Bcl-2, as well as the protein levels of p-PI3K, p-Akt, p-GSK-3β, p-CREB, and Bcl-2 (P<0.01). In comparison to the model group, both the JuA and donepezil groups demonstrated improvements in the learning and memory abilities (P<0.05, P<0.01), with reduced neuronal damage and increased neurons (P<0.05, P<0.01). In addition, the two groups showed down-regulation in the mRNA level of GSK-3β (P<0.01) and up-regulation in the mRNA levels of PI3K, Akt, CREB, and Bcl-2 and the protein levels of p-PI3K, p-Akt, p-GSK-3β, p-CREB, and Bcl-2 (P<0.05, P<0.01). There were no statistically significant differences between the blank control and sham operation groups in terms of the learning and memory abilities, neuron count, and mRNA and protein levels of PI3K/Akt/GSK-3β pathway-related factors. ConclusionJuA can ameliorate the cognitive impairment in the rat model of VCI by activating the PI3K/Akt signaling pathway, reducing the apoptosis of hippocampal neurons, and alleviating the hippocampal neuronal damage.

ObjectiveTo analyze the epidemic characteristics of measles and rubella in Pudong New Area of Shanghai from 2013 to 2022, and to provide data support for the elimination of measles and rubella. MethodsEnzyme linked immunosorbent assay was used to detect IgM antibodies in serum samples. The sequence of 630 nucleotides at the C-terminal of N gene of measles virus was amplified by reverse transcription-polymerase chain reaction and the phylogenic tree was constructed. ResultsA total of 1 529 suspected cases of measles were detected from 2013 to 2022, among which the positive rate of measles IgM antibody was 33.55% (513/1 529). The highest positive rate (20.73%) was from March to May , and the positive rate of rubella IgM antibody was 6.80% (104/1 529). The positive rate of both IgM was higher in males than that in females (P<0.05). The IgM against measles was mainly detected in 0‒ years old (63.16%, 96/152) and 20‒ years old (45.61%, 161/353). The IgM against rubella was mainly detected in 10‒20 years old (27.27%, 18/66). The IgM antibody could be detected more easily from 4 to 28 days after eruption, and the IgM antibody positive rate of measles/rubella from 2020 to 2022 was significantly lower than previous years (2013‒2019). There were 2 D8 genotype strains, and the rest were H1a gene subtypes. ConclusionThe positive rate of IgM antibodies against measles/rubella in Pudong New Area of Shanghai decreased significantly. People aged 0‒ years and 20‒ years old are more susceptible to measles, and rubella is concentrated in 10‒ years old. It is necessary to strengthen the vaccination of school-age children, in order to achieve the goal of eliminating measles. The age group with high risk of exposure should be checked for vaccination status to ensure the enhanced immunization, and the surveillance of imported measles cases should be strengthened.
