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 clinical characteristics of encephalocraniocutaneous lipomatosis (ECCL) in pediatric patients.Methods:A retrospective analysis was conducted on the clinical data of 2 ECCL cases admitted to Children′s Hospital Affiliated to Zhengzhou University between January 2024 and December 2024. Additionally, a review of relevant literature was performed to summarize the clinical features of this condition.Results:Case 1 is a male patient aged 2 years and 10 months, while case 2 is a female patient aged 8 months. Both patients presented with seizures and exhibited nevus psiloliparus on the scalp, non-scarring alopecia, nodular skin tags around the eyes, and ocular choristomas. Brain magnetic resonance imaging revealed leptomeningeal angiomatosis in both cases, with case 1 also demonstrating an intracranial lipoma and case 2 showing localized cerebral atrophy and an arachnoid cyst. Whole-exome sequencing of peripheral blood and copy number variation analysis in both cases did not identify any pathogenic variants. Additionally, no relevant pathogenic variants were detected in the scalp lesion tissue of case 2. A review of the literature revealed that, to date, there have been 5 reported domestic cases, 132 reported foreign cases in pediatric populations, totally 139 cases including 2 cases described in this article. Among these patients, 86 are male, 49 are female, and the gender of 4 cases remains unspecified. Clinical manifestations observed included seizures in 79.0% (64/81) of cases and developmental delay in 64.7% (57/88). Cutaneous lesions were characterized by non-scarring alopecia in 100% (97/97) of cases,non-hair-bearing fatty tissue nevi in 98.3% (58/59), nodular skin tags in 96.5% (56/58), and subcutaneous lipomas in 94.8% (73/77). Ocular lesions predominantly involved choristomas, occurring in 91.8% (90/98) of cases. Central nervous system abnormalities were identified as ventricular dilatation or hydrocephalus in 85.0% (68/80) of cases, intracranial lipomas in 82.1% (69/84), localized cerebral atrophy in 80.9% (34/42), intracranial vascular anomalies in 74.1% (23/31), and spinal lipomas in 66.6% (30/45).Conclusions:ECCL is an uncommon neurocutaneous disorder with the potential to impact various organ systems, notably the integumentary, ocular, and central nervous systems. Pediatric patients may exhibit symptoms such as seizures, developmental delays, and additional clinical manifestations, necessitating vigilant monitoring and management.

Objective To investigate the effects and mechanisms of Huatan Quyu Decoction on learning and memory abilities in rats with vascular dementia(VD).Methods Totally 112 male SD rats were randomly selected with 16 rats as the sham-operation group,the remaining rats were used to prepare VD models by segmental ligation of the common carotid artery.The successfully modeled rats were randomly divided into model group,Huatan Quyu Decoction low-,medium-and high-dosage groups(6.1,12.1,24.2 g/kg),donepezil hydrochloride group(0.5 mg/kg)and combination group(Huatan Quyu Decoction 12.1 g/kg+donepezil hydrochloride 0.5 mg/kg),with 16 rats in each group.Each group was given the corresponding treatment measures for 4 weeks.The Morris water maze test was used to assess learning and memory abilities,neurological function was evaluated using Garcia score,HE staining was used to observe the morphology of the hippocampal tissue,ELISA was employed to detect the serum content of Aβ,immunohistochemistry was utilized to observe the β-catenin,LRP6 and GSK-3β protein expression in brain tissue.Results Compared with the sham-operation group,the escape latency of the model group rats was prolonged(P<0.01),the number of crossing platforms was reduced(P<0.01),and the neurological deficit score was decreased(P<0.01),the arrangement of hippocampal tissue cells was disorderly,and the tissue was severely damaged,the serum Aβ content increased(P<0.01),the expressions of β-catenin and LRP6 protein in brain tissue decreased,and the expression of GSK-3β protein increased(P<0.01).Compared with the model group,the escape latency of rats in each administration group was shortened,the number of crossing platforms increased,the neurological deficit score increased,the number of hippocampal cells was relatively more,the arrangement was more orderly,and the structure was relatively complete,the serum Aβ content decreased,the expressions of β-catenin and LRP6 proteins increased,and the expression of GSK-3β protein decreased.Among them,Huatan Quyu Decoction high-dosage group had a significantly better effect than Huatan Quyu Decoction low-and medium-dosage groups(P<0.01),and there was no statistical significance in various indicators compared with the donepezil hydrochloride group(P>0.05).Compared with the donepezil hydrochloride group,the combination group showed significant improvements in learning and memory abilities(P<0.01),the neurological deficit score significantly increased(P<0.01),the number of hippocampal cells significantly increased,arranged neatly,and structurally intact,the serum Aβ content significantly decreased(P<0.01),the expression of β-catenin and LRP6 proteins significantly increased,and the expression of GSK-3β protein significantly decreased(P<0.01).Conclusion Huatan Quyu Decoction can repair cognitive function in VD rats,improve learning and memory abilities,and alleviate VD symptoms by activating the Wnt/β-catenin signaling pathway to reduce serum Aβ content,decrease the apoptosis of nerve cells and alleviate the degree of pathological damage in hippocampal tissue.

Objective To investigate the prevalence of hyperuricemia among ethnic groups in Gongshan county,Yunnan province through a cross-sectional study.Methods A total of 229 residents aged ≥ 18 years from Dulong,Nu,Tibetan,Bai and Lisu ethnic groups were randomly selected in Gongshan County of Yunnan Province for questionnaire survey,physical examinations and laboratory tests.SPSS 22.0 was used for t test,Chi-square test,correlation analysis,and multivariate logistic regression analysis.Results A total of 107 cases of hyperuricemia were identified,with a detection rate of 46.7％,among which the prevalence was 43.9％in males,52.63％in female,48％in the Dulong,51％in the Lisu,47％in the Nu,37.5％in the Bai,52％in the Tibetan and 50％in the Han.There were no statistically significant differences in prevalence among all nationalities(P＞0.05).The proportion of individuals with a history of diabetes,as well as levels of urea nitrogen and serum creatinine,were significantly higher in the hyperuricemia group compared to the non-hyperuricemia group(P＜0.05).Correlation analysis showed a positive correlation between hyperuricemia and diabetes,urea nitrogen and serum creatinine.(P＜0.05).Multivariate regression analysis showed that diabetes and elevated serum creatinine were independent risk factors for the onset of hyperuricemia(P＜0.05).Conclusion The detection rate of hyperuricemia is relatively high in Gongshan County,Yunnan Province,and there is no significant differences in prevalence among ethnic groups.Diabetes and elevated serum creatinine are associated with hyperuricemia,which increase the risk of developing hyperuricemia.

Conclusion:Huatan Quyu Decoction can activate the Wnt/β-catenin signaling pathway, up-regulate the expression of β-catenin protein in hippocampal tissue of rats, inhibit the expression of GSK-3β, reduce the levels of ACA and Aβ in serum of rats, and improve the cognitive function of rats with vascular dementia.

Objective    To explore the distribution pattern of respiratory symptoms and relevant factors in patients with pulmonary nodules. Methods    Demographic and clinical information were collected from patients who visited the Thoracic Surgery Outpatient Clinic of Guangdong Provincial People’s Hospital from January 2021 to January 2022. Hospital Anxiety and Depression Scale (HADS) was used to assess their anxiety and depression level. Results    A total of 1 173 patients were enrolled, including 449 males and 724 females, with an average age of 46.94±11.43 years. Among the patients with pulmonary nodules, 37.7% of them had at least one respiratory symptom; 24.4% had cough, 14.0% had expectoration, 1.3% had hemoptysis and 14.9% had chest pain. Old age, male, exposure to second-hand smoking or environmental smoke, hair coloring and history of tuberculosis were major risk factors for respiratory symptoms (P<0.05). Middle age, old age, male, exposure to environmental smoke were major risk factors for cough (P<0.05); old age, smoking, larger maximum nodules diameters, exposure to environmental smoke and history of pneumonia were major risk factors for expectoration (P<0.05); male, multiple nodules, hair coloring, exposure to second-hand smoking and history of tuberculosis were major risk factors for chest pain (P<0.05). Symptomatic patients showed generally higher HADS scores than asymptomatic patients (P<0.001). Conclusion    Cough, expectoration and chest pain are the predominant respiratory symptoms for patients with pulmonary nodules. The presentation of respiratory symptoms increases patients' anxiety and depression.

Centenarians are known as the "model population" in the study of healthy aging. Understanding their characteristics of health and longevity and its related influencing factors would facilitate the exploration of the possible path to achieve health and longevity under the background of population aging in China. In recent years, the population based observational studies, including China Hainan Centenarian Cohort Study (CHCCS), have found the main health characteristics of centenarians and their relationship with quality of life. This paper summarizes the relevant research results from CHCCS in recent years, and compare them with the results of similar domestic studies. The main health indicators include blood pressure, blood lipid, blood glucose, hemoglobin, body measurement and renal function. The health outcomes including diet, nutrition, health-related quality of life, activities of daily living, geriatric syndrome. The results are expected to provide epidemiological evidence for the development of healthy aging policies.
