Objective: To investigate the impact of childhood traumatic experiences on individual risktaking decisions in early adulthood using functional nearinfrared spectroscopy (fNIRS), so as to provide the reference for clarifying the brain mechanisms underlying the impact of childhood trauma on individual risky decision. Methods: From December 2023 to March 2024, 28 children with childhood trauma experiences (trauma group) and 32 healthy college students (control group) were selected from Jining Medical University by a combination of stratified descent and convenient sampling methods. All subjects participated in the Iowa Game task fNIRS scanning. The brain activation, functional connectivity, graph theory properties (degree centrality, betweenness centrality, and local efficiency), and Receiver Operating Characteristic (ROC) analysis were performed by using preprocessing fNIRS data. Results: Compared with control group, trauma group showed significantly fewer choice times in the inferior deck (Z=-0.88), and showed significantly decreased activation levels in the right frontalpolar (Z=-2.59), as well as showed significant decreased functional connectivity between left dorsolateral prefrontal and in right dorsolateral prefrontal (Z=-3.78), and between left dorsolateral prefrontal cortex and the right frontal pole (Z=-3.68)(P<0.05). The central index of right inferior frontal gyrus in the trauma group was higher than that in the control group, while the central index of left and right dorsolateral frontal lobes was lower than that in the control group (Z=2.13, -2.53, -2.12, P<0.05). The centrality index of the right inferior frontal gyrus in the trauma group was higher than that in the control group (Z=2.47, P<0.05). The local efficiency indicators of the right inferior frontal gyrus, left and right frontal pole in the trauma group were higher than those in the control group (Z=2.51, 2.17, 2.53, P<0.05). The results of the ROC curve analysis showed that the local efficiency achieved the highest area under the curve (AUC=0.68). Conclusions Young adults with childhood trauma experience tend to choose lower loss, and the frontal pole shows a lack of activation in the whole process of risk decision performance. The abnormalities in the brain connectivity and network properties might be the neural basis of excessive defense mechanisms that childhood trauma leads to risky decisions.

Objective:To understand the prevalence of major chronic diseases of diabetes, cardiovascular disease and malignant tumor in people living with HIV in Taizhou.Methods:The data were collected from China Information System for Disease Control and Prevention and Taizhou Chronic Disease Information Management System. A total of 5 126 people living HIV under follow-up in Taizhou from 1998 to 2022 were included in the analysis. Software SAS 9.4 was used for χ 2 test, trend analysis and logistic regression analysis. Results:In the 5 126 people living with HIV, the reported prevalence rates of diabetes,cardiovascular disease and malignant tumor were 10.28% (527/5 126),3.98% (204/5 126) and 6.01% (308/5 126), respectively. 37.00% (195/527) and 48.58% (256/527), 40.20% (82/204) and 48.53% (99/204), 37.66% (116/308) and 48.38% (149/308) were diagnosed as diabetes, cardiovascular disease and malignant tumor before and after confirmation of HIV infection. From 2013 to 2022, the proportion of HIV infected people diagnosed with diabetes, cardiovascular disease and malignant tumor after confirmation increased (trend χ2=79.98, P<0.001; trend χ2=17.44, P<0.001; trend χ2=32.06, P<0.001). Based on the analysis on the factors for complicated chronic diseases in people living with HIV, it was found that women under 60 years old (a OR=0.66, 95% CI: 0.50-0.86) and those with access to antiviral treatment for >5 years before 2016 (a OR=0.54,95% CI:0.37-0.78) were less likely to develop complicated chronic diseases, and those under 60 years old with initial CD4 +T lymphocytes counts <200 cells/μl (a OR=1.32, 95% CI: 1.02-1.70), those aged 40-49 and 50-59 years (a OR=2.88, 95% CI:2.20-3.79; a OR=5.43, 95% CI: 4.10-7.21) as well as those without a record of treatment medication use after 2016 (a OR=1.95,95% CI:1.20-3.16) were more likely to develop complicated chronic diseases. The probability of developing complicated chronic diseases might increase with age in people living with HIV. Conclusions:From 1998 to 2022, there was a certain proportion of complicated chronic diseases among HIV infected individuals in Taizhou, and the proportion of diagnosed cases increased after HIV infection was confirmed. It is necessary to conduct early chronic disease screening, behavior intervention and standardized management in people living with HIV.

Spinal muscular atrophy (SMA), an autosomal recessive neuromuscular disease with a carrier frequency of 1/60 ~ 1/40, is characterized by severe clinical symptoms, high mortality rate, and expensive treatment costs. Carrier screening is of paramount importance to detect high-risk couples, and therefore to reduce the occurrence of SMA. In China, SMA carrier screening has become widespread, though there is still a lack of genetic counseling expertise. This article has focused on the current challenges for SMA carrier screening, including the screening methods, target population, screening procedures, and pre-/post-testing counseling. The aim is to standardize its application and counseling in the clinical practice.

The new-generation non-invasive prenatal screening technology (NIPT2.0) is a new method successfully realized in recent years based on high-throughput sequencing to synchronously and accurately detect fetal chromosomal aneuploidies, microdeletion/microduplication syndromes and dominantly inherited monogenic disorders. NIPT2.0 can circumvent the shortcomings of previous non-invasive prenatal screening techniques (NIPT and NIPT Plus) including incapability to detect fetal monogenic disorders, insufficient accuracy of detection and low positive predictive values for certain chromosomal abnormalities (in particular trisomy 13, sex chromosomal abnormalities, and small-segment microdeletions and microduplication syndromes). How to apply NIPT2.0 reasonably and normatively to maximize its clinical value has become an issue which requires clarification. The Reproductive Health Branch of the Chinese Maternal and Child Health Care Association has organized experts to fully discuss and jointly drafted this consensus, which has put forwards suggestions over the clinical application strategy for NIPT2.0, including the scope of application, target disease, pre-test consultation, clinical application pathway, post-test genetic counseling and intervention, quality control and limitations, for the reference by peers, with a view to standardize its application and provide better clinical service.

Birth defects are an important factor for the quality of newborn population. With the development of molecular genetic technology, an increasing number of genetic disorders leading to birth defects can now be detected. The lack of the knowledge for the basics and clinical applications of molecular genetic techniques have emerged as a shortcoming for primary care physicians who have formed the first tier prevention for birth defects. Currently, government has paid more attention to the above problems and formulated more training programs for primary obstetricians and gynecologists, e.g., "Prenatal Screening and Prenatal Diagnosis Post Training Program", "National Birth Defects Training Program", "National Primary Obstetrician Training Program". To some extent, such programs have met the urgent need for birth defect prevention in primary hospitals. But at the same time, some problems have also emerged. For instance, the knowledge for birth defects among primary obstetricians and gynecologists is poor, and there is lack of young personnel. This article has aimed to discuss the strategies to systematically improve the ability for preventing birth defects among primary care physicians by analyzing the obstacles and challenges for primary obstetricians and gynecologists in the era of molecular genetic testing.

OBJECTIVE: To explore the genetic basis for four patients suspected for Marfan syndrome (MFS). METHODS: Four male patients with suspected MFS and their family members who were treated at West China Second Hospital of Sichuan University from September 12, 2019 to March 27, 2021 were selected as the study subjects. Peripheral venous blood samples were collected from the patients and their parents or other pedigree members for the extraction of genomic DNA. Whole exome sequencing was carried out, and candidate variants were validated by Sanger sequencing. The pathogenicity of the variants was determined based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). RESULTS: Genetic testing revealed that all four patients have harbored variants of the FBN1 gene, including c.430_433del (p.His144fs) deletional variant in exon 5, c.493C>T (p.Arg165*) nonsense variant in exon 6, c.5304_5306del (p.Asp1768del) deletional variant in exon 44 and c.5165C>G (p.Ser1722Cys) missense variant in exon 42. According to the ACMG guidelines, the c.430_433del and c.493C>T were classified as pathogenic variants (PVS1+PM2_Supporting+PP4; PVS1+PS1+PS2+PM2_Supporting+PP4). c.5304_5306del and c.5165C>G were classified as likely pathogenic variants (PS2+PM2_Supporting+PM4+PP4; PS2_Moderate+PS1+PM1+PM2_Supporting). CONCLUSION The c.430_433del and c.5304_5306del variants of the FBN1 gene identified in this study were unreported previously. Above results have enriched the variation spectrum of the FBN1 gene and provided a basis for genetic counseling and prenatal diagnosis of patients with MFS and acromicric dysplasia.

ObjectiveTo analyze the changes in HIV， syphilis and hepatitis C prevalence among men who have sex with men （MSM） in Taizhou City， Zhejiang Province from 2017 to 2022， and the utilization of HIV intervention services and its influencing factors. MethodsMSM participants were recruited from HIV sentinel surveillance in Taizhou through snowball sampling method. Participants’ socio-demographic characteristics， sexual behavior characteristics， knowledge of HIV and utilization of HIV intervention services were collected and statistically described by questionnaire survey. Blood samples from MSM sentinel population were also collected for HIV， syphilis， and HCV antibody testing. Multivariate logistic regression analysis was used to analyze the influencing factors for utilizing HIV intervention services among MSM. ResultsA total of 2 499 MSM were included in the analysis from 2017 to 2022， with HIV prevalence of 5.8%， syphilis prevalence of 4.0%， and HCV prevalence of 0.6%. The infection rate， proportion of homosexual anal sex and heterosexual sex showed a decreasing trend， while the proportion of condom use during homosexual anal sex， condom publicity and distribution， AIDS consultation and testing， acceptance of peer education， and online temporary homosexual sex showed an increasing trend. All these differences were statistically significant. Multivariate logistic regression analysis showed that COVID-19 epidemic （aOR=1.66， 95%CI：1.04‒2.64） and HIV knowledge awareness （aOR=2.57， 95%CI：1.22‒5.40） were positively correlated with increased acceptance of condom publicity and distribution， and utilization of AIDS counseling and testing. Those who sought male sexual partners through offline route （aOR=3.44， 95%CI： 1.16‒10.21）， and had a history of sexually transmitted diseases within one year （aOR=5.47， 95%CI： 1.04‒28.76） were positively correlated with community-based methadone maintenance therapy， clean needle provision and exchange services， while COVID-19 epidemic （aOR=0.35， 95%CI： 0.14‒0.88） was negatively correlated with the utilization of these services. COVID-19 epidemic （aOR=2.11， 95%CI： 1.54‒2.89）， HIV knowledge awareness （aOR=2.09， 95%CI： 1.08‒4.02）， offline search for male sexual partners （aOR=1.47， 95%CI： 1.03‒2.11）， and awareness of HIV infection of sexual partners （aOR=2.09， 95%CI： 1.62‒2.69） were positively correlated with the increased use of peer education service， while married or cohabited （aOR=0.73， 95%CI： 0.55‒0.98） and VCT （aOR=0.61， 95%CI： 0.46‒0.82） were negatively correlated with utilization of peer education service. ConclusionHIV infection rate of sentinel MSM population in Taizhou decreases， while the utilization of HIV intervention services increases in general. Targeted measures should be developed according to the changes in sexual behavior and HIV intervention services among MSM populations in Taizhou to improve the HIV intervention services for the MSM population.

Objective:To understand the incidence and causes of HIV/AIDS death patients in Taizhou from 1998 to 2022.Methods:The data were collected from the AIDS Integrated Prevention and Control Information System of China Information System for Diseases Control and Prevention and Taizhou Chronic Disease Information Management System. By the end of 2022, a total of 5 126 HIV/AIDS patients living in Taizhou for a long time were included, SAS 9.4 was used for Kruskal-Wallis test, χ2 test and trend analysis. Results:From 1998 to 2022, a total of 796 HIV/AIDS patients died, with a fatality rate of 15.53% (796/5 126), in whom 52.26% (416/796) died within one year after confirmation. The proportion of HIV/AIDS patients who died within one year decreased (trend χ2=5.60, P<0.001). For the constituent of death causes, there were 140 (17.59%) deaths of AIDS, 237 (29.77%) deaths of malignant tumors, 99 (12.44%) deaths of cardiovascular disease, 58 (7.29%) deaths caused by injuries, 160 (20.10%) deaths due to other causes, and 102 (12.81%) deaths due to unknown causes. The constituent ratio of deaths of malignant tumor, cardiovascular disease and other causes increased over time (trend χ2=1.92, P=0.028; trend χ2=2.81, P=0.003; trend χ2=2.07, P=0.020). There were differences in the distribution of death causes in HIV/AIDS cases in terms of age, occupation, marital status, ethnic group, educational level and mode of transmission (all P<0.05). The average age of the death cases due to cardiovascular disease was higher than other death cases, the cases who died from AIDS had shorter survival time and the lower initial CD4 +T cells after confirmation compared with all other death cases, and the time interval from confirmation to treatment in HIV/AIDS patients with unknown death causes was longer than those of all other death cases (all P<0.05). Conclusions:The constituent ratio of non-AIDS related deaths in HIV/AIDS patients in Taizhou was relatively high and showed an upward trend during 1998-2022. It is necessary to further strengthen the early screening, prevention and treatment of chronic non infectious diseases.

ObjectiveTo determine the prevalence of hepatitis C virus （HCV） infection and identify the underlying risk factors among drug users in Taizhou City of Zhejiang Province during 2009‒2020. MethodsA consecutive cross-sectional survey was conducted. A total of 400 drug users in correctional settings were randomly selected from April to August. The drug users were interviewed with a questionnaire to collect demographic characteristics， AIDS-related knowledge， detoxification service， drug use， and sexual behavior. Blood samples were then collected for anti-HCV antibody testing. Chi-square test and multivariate conditional logistic regression were used. ResultsA total of 5 042 drug users were included in this study. Seroprevalence of HCV was determined to be 22.7%. From 2009 to 2019， the seroprevalence showed a significant downward trend， from 34.9% to 8.8% （χ²=221.025， P<0.001）. However， in 2020， the seroprevalence was 12.7%. The multivariate logistic regression analysis showed that senior age （≥25 years old）， cohabitation， taking traditional or mixed drugs， injection drug use， and needle sharing were risk factors associated with HCV seroprevalence. ConclusionSince 2009， HCV seroprevalence among drug users in Taizhou City has shown a downward trend， however， it has increased slightly in 2020. It warrants strengthening prevention and treatment measures in response to risk factors related to HCV infection among drug users.
