Objective:To investigate the life expectancy of antiretroviral treatment (ART) HIV-infected patients and its trends in Taizhou City, Zhejiang Province from 2014 to 2023.Methods:The data were obtained from the China Information System for Disease Control and Prevention , and the study subjects were HIV-infected patients received ART in Taizhou City. An abbreviated life expectancy table was prepared based on Chiang's method to analyze the differences in life expectancy of HIV-infected patients receiving ART in Taizhou City with different characteristics in 2023 and to compare the trends in life expectancy of patients with different CD4 +T lymphocytes (CD4) counts at the time of initiation of ART from 2014 to 2023. Results:A total of 4 825 patients were enrolled in this study, with a cumulative follow-up of 276 648.56 person-years, and a case-fatality rate of 18.07 (95% CI: 16.48-19.65) /1 000 person-years. In 2023, male patients had lower life expectancy than females in all age groups, and those who were married had higher life expectancy than those who were unmarried and those who were divorced or widowed; patients who had been transmitted heterosexually had lower life expectancy than those who had been transmitted through homosexual transmission. Patients with different CD4 counts at the time of initiating ART had different life expectancies in all age groups. The life expectancy of patients with CD4 counts ≥350 cells/μl when initiating the treatment was higher than that of patients with CD4 counts <200 cells/μl in all age groups. The life expectancy of HIV-infected patients on ART at age 20 and 50 increased from 39.0 years and 19.1 years in 2014 to 46.0 years and 24.1 years in 2023, respectively, with an average annual percentage change of 2.43% (95% CI: 0.81%-4.07%) and 3.34% (95% CI: 1.17%-5.56%). The change in life expectancy was similar for patients with CD4 counts ≥350 cells/μl and 200-349 cells/μl at the time of initiating treatment in 2016-2023, and was higher than that for patients with CD4 counts <200 cells/μl. The rate of increase in life expectancy for patients at age 50 was higher than that at age 20 for all CD4 counts. Conclusions:The rising trend of life expectancy among HIV-infected patients on ART in Taizhou City is obvious. But the disparity between patients with different characteristics is obvious, especially among patients with baseline CD4 counts <200 cells/μl, suggesting the importance of expanded testing, early diagnosis and timely initiation of ART to improve the life expectancy of HIV-infected patients.

Objective:To investigate the functional characteristics of the prefrontal cortex in patients with schizophrenia (SCZ) during resting state and analyze its association with clinical symptoms.Methods:Twenty-eight hospitalized patients with SCZ (SCZ group) were selected from November 2023 to May 2024, and 28 healthy controls (HC group) were recruited concurrently. By using functional near-infrared spectroscopy (fNIRS) technology, data on the concentration changes of oxygenated hemoglobin (HbO) and deoxygenated hemoglobin (HbR) in the prefrontal cortex during resting state were collected from all subjects to measure cortical hemodynamic activity. Regional activation values and functional connectivity (FC) values among brain areas were analyzed. Clinical symptoms in patients were assessed using the positive and negative syndrome scale (PANSS).SPSS 25.0 software was employed for statistical analysis. Between-group comparisons were performed using independent samples t-tests or Mann-Whitney U tests. Spearman correlation analysis and general linear regression models were applied to examine relationships between prefrontal cortical functional characteristics and clinical symptoms. Results:The levels of HbO in the right inferior frontal gyrus and left frontal pole area were significantly higher in the SCZ group (1.5 (1.0, 3.0)μmol/L, 1.0 (1.0, 2.8)μmol/L) than those in the HC group (-0.01 (-0.05, 0.02)μmol/L, -0.02 (-0.07, 0.03)μmol/L) ( Z=-6.46, -6.50, both P<0.01). The levels of HbR in the bilateral dorsolateral prefrontal cortex were significantly higher in the SCZ group (0.02 (-0.01, 0.07)μmol/L, 0.01 (-0.01, 0.03)μmol/L) than those in the HC group (-0.01 (-0.03, 0.01)μmol/L, -0.01 (-0.02, 0.01)μmol/L) ( Z=-2.46, -1.98, both P<0.05).The SCZ group showed significantly higher HbO-based FC values in the frontal pole-temporal pole (0.49±0.21) and temporal pole-dorsolateral prefrontal cortex (0.36±0.25) compared to the HC group (0.33±0.18, 0.15±0.19) ( t=3.02, 3.44, both P<0.01). Conversely, the SCZ group exhibited significantly lower HbR-based FC in the frontal pole-inferior frontal gyrus (0.15±0.13) and inferior frontal gyrus-temporal pole (0.27±0.37) compared to the HC group (0.33±0.26, 0.77±0.48) ( t=-3.17, -4.23, both P<0.01). Correlation analysis revealed that in the SCZ group, the level of HbO in the right inferior frontal gyrus was positively correlated with negative symptoms, positive symptoms, excitement/hostility, and PANSS total score ( r=0.45-0.64, all P<0.05), and the level of HbO in the left frontal pole area was positively correlated with excitement/hostility and PANSS total score ( r=0.57, 0.50, both P<0.01), while the FC value between the frontal pole and temporal pole areas showed a negative correlation with excitement/hostility ( r=-0.39, P<0.05). Regression analysis demonstrated that, the HbO concentration in the right inferior frontal gyrus significantly positively predicted PANSS total score, positive symptoms, and negative symptoms ( β=0.70, 0.64, 0.55, all P<0.01).The HbO concentration in the left frontal pole area significantly positively predicted excitement/hostility ( β=0.77, P<0.01).The frontal pole-temporal pole HbO-based FC significantly negatively predicted excitement/hostility scores ( β=-0.42, P<0.01). Conclusion:Patients with SCZ exhibit hyperactivation of localized prefrontal cortex brain regions and dysfunction of functional connectivity during resting state, which are significantly associated with core clinical symptoms including positive, negative, and excitement/hostility symptoms.

Objective:To explore the genetic basis of a patient with suspected Oculocutaneous albinism (OCA).Methods:An OCA patient presented at the West China Second Hospital of Sichuan University and his mother were selected as the study subjects. Peripheral blood samples were collected for the extraction of genomic DNA, and whole exome sequencing (WES) was carried out. Candidate variants were verified through specific primer amplification, Sanger sequencing, and agarose gel electrophoresis. Bioinformatic analysis and pathogenicity rating were conducted on the candidate variants. This study has been approved by the Medical Ethics Committee of West China Second Hospital (No. 2024-228).Results:Genetic testing revealed that the patient had harbored variants in exon 1 of the TYR gene, including a c. 157G>T (p.G53C) missense variant and a c. 609dup (p.A204fs) frameshifting variant. Specific primer amplification and Sanger sequencing, combined with agarose gel electrophoresis, confirmed that these are compound heterozygous variants. Based on the guidelines from the ACMG, the c. 157G>T was rated as likely pathogenic, and c. 609dup was rated as pathogenic. Alphafold3 predicted that the variant proteins had significant structural changes. Conclusion:The patient was diagnosed with OCA due to compound heterozygous variants of the TYR gene. Discovery of the c. 609dup variant has enriched the mutational spectrum of OCA and provided a basis for genetic counseling and prenatal diagnosis for this patient.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.

Objective:To evaluate the relationship between preoperative serum bilirubin concentrations and postoperative delirium (POD) in the patients undergoing knee or hip replacement.Methods:Medical records from 413 patients undergoing knee or hip arthroplasty were selected from August 2020 to October 2023 at Qingdao Municipal Hospital using a nested case-control design based on the PNDABLE study cohort. The patients were divided into POD group ( n=77) and non-POD group ( n=336) according to whether POD occurred. Univariate analysis was used to analyze the influencing factors. Logistic regression was used to identify the risk factors for POD. The significance of mediation effect was tested. The receiver operating characteristic curve was drawn to evaluate the accuracy of risk factors in predicting POD. Results:There were significant differences in age, education time, ratio of diabetes history, Memorial Delirium Assessment Scale score, total bilirubin concentration, direct bilirubin concentration, indirect bilirubin concentration, Aβ 42 concentration, p-tau concentration, t-tau concentration, Aβ 42/p-tau ratio and Aβ 42/t-tau ratio between POD group and non-POD group ( P<0.05). The results of logistic regression analysis showed that preoperative serum total bilirubin, direct bilirubin and indirect bilirubin were risk factors for POD ( P<0.05). The results of mediation effects showed that the concentration of total tau protein in CSF partly mediated the relationship between high serum total bilirubin, direct bilirubin and indirect bilirubin concentrations and POD. The area under the receiver operating characteristic curve of total bilirubin, direct bilirubin and indirect bilirubin combined with CSF biomarker concentrations in predicting POD was 0.83 ( P<0.001). Conclusions:Preoperative elevated concentrations of total bilirubin, direct bilirubin and indirect bilirubin are risk factors for POD in the patients undergoing knee or hip replacement. CSF t-tau concentration has a partly mediating role in the association between serum total bilirubin, direct bilirubin and indirect bilirubin concentrations and the development of POD.

Objective: To investigate the level and influencing factors of mental health literacy among middle school students in Taizhou City, Zhejiang Province, so as to provide the basis for the development of mental health education and intervention. Methods: Middle school students were selected from six counties (districts) in Taizhou City using the random cluster sampling method. Demographic information, disease history, learning status, and relationship with parents were collected through questionnaire surveys. The level of mental health literacy was investigated using the Structured Mental Health Literacy Questionnaire for Middle School Students. The influencing factors for mental health literacy was analyzed using a multiple linear regression model. Results: A total of 7 173 middle school students were surveyed, including 4 273 junior high school students (59.57%) and 2 900 high school students (40.43%), and had a mean age of (15.52±1.49) years. There were 3 644 male students (50.80%) and 3 529 female students (49.20%). The median score of mental health literacy was 83.00 (interquartile range, 23.00) points. Multiple linear regression analysis revealed that older age (β'=0.074), female gender (β'=0.038), living in urban areas (β'=0.029), good family economic status (β'=0.061), engaging in sports (β'=0.122), having a good relationship with the father (β'=0.128), and having a good relationship with the mother (β'=0.094) were associated with higher mental health literacy scores among middle school students; while having a history of disease (β'=-0.144) and learning difficulties (β'=-0.178) were associated with lower mental health literacy scores. Conclusion The level of mental health literacy among middle school students in Taizhou City is relatively good, and is influenced by demographic characteristics, disease history, sports participation, learning and relationships with parents.
