Aging has emerged as a cutting edge and hotspot in global life science field， with anti-aging and geriatric disease prevention and treatment becoming critical issues urgently demanding solutions in international medical communities. In the face of the challenge of accelerating global population aging， in-depth exploration of aging mechanisms and the development of effective intervention strategies hold significant scientific and clinical value. This study supported by the national key research and development program of China， employed the essence-Qi-spirit theory of Qiluo doctrine as its guiding framework， focusing on the key scientific issue of the core traditional Chinese pathogenesis of aging， namely "depletion of kidney essence， deficiency of primordial Qi， and impairment of body and spirit". The treatment principle of "tonifying the kidney to replenish essence， harmonizing Yin and Yang， warming and invigorating primordial Qi， and nourishing the body and spirit" was established. Centered on holistic aging， systemic aging， and aging-related diseases， the research integrated multidisciplinary research approaches to construct multi-modal aging models and a multi-dimensional evaluation system， and it utilized multi-omics technologies to deeply analyze aging mechanisms. By systematically reviewing historical kidney-tonifying and anti-aging formulas and combining big data with artificial intelligence technologies， an information database of anti-aging traditional Chinese medicine substance was developed to reveal the differences and synergistic effects of various treatment methods and formulas on anti-aging. Based on this treatment method， the research integrated two millennia of kidney-tonifying medicinal experience to develop the innovative anti-aging traditional Chinese medicine， namely Bazhi Bushen capsules. It was validated that this capsule can delay holistic and systemic aging through multiple targets and mechanisms， thereby elucidating the scientific connotation of the essence-Qi-spirit theory of Qiluo doctrine in guiding anti-aging research from multiple dimensions and providing robust support for leveraging the advantages of traditional Chinese medicine to occupy the commanding heights of international anti-aging research.

Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

ObjectiveTo retrospectively analyze the association between novel coronavirus (“SARS-CoV-2”) infection and clinical symptoms in inpatients with severe acute respiratory infection (SARI) in Pudong New Area, Shanghai, so as to provide evidence for improving clinical diagnostic ability. MethodsFrom January 13 to March 2, 2023, respiratory tract specimens of 456 inpatients with SARI were collected from 8 sentinel institutions, SARS-CoV-2 was detected by real-time fluorescence quantitative PCR. Whole genome sequencing and sequence analyses were performed to samples with a cycle threshold (Ct) value of <35. At the same time, demographic information, clinical characteristics and underlying disease condition of the cases were collected, and the association between age, symptoms and nucleic acid positive rates was evaluated by χ² test and Spearman correlation analysis. ResultsA total of 456 cases were included, the median (P₂₅, P₇₅) age was 70 (69, 85) years old, of which 200 cases were novel coronavirus nucleic acid positive for SARS-CoV-2, with a positive rate of 43.86%. The positive rate was the highest in the 80-year-old group (56.82%), and the positive rate increased significantly with age (r=0.15, P=0.002). The proportion of oppression in chest, sore throat and expectoration in novel coronavirus nucleic acid positive cases was significantly higher than that in negative cases (all P<0.05). The 33 viruses sequenced successfully were all Omicron subvariants, with BF.7 (51.52%) and BA.5.2 (42.42%) being the predominant ones. ConclusionA positive correlation was observed between advanced age and the risk of SARS-CoV-2 positivity in patients with SARI. The symptoms of expectoration, oppression in chest and sore throat are more common in positive cases, which can be used as a prompt indicator for key screening and clinical identification of elderly SARI cases.

Abstract Polycystic ovarian syndrome(PCOS) is a very common endocrine and reproductive disease. Its etiology and pathogenesis are complex and not yet fully clear. At present, the clinical treatment is mainly symptomatic. Studies have revealed that ferroptosis, as a new form of cell death, may play a key regulatory role in the occurrence and development of PCOS. In addition, there is an increase in autophagy/mitochondrial autophagy in PCOS patients, which may be closely related to the occurrence of ferroptosis. This review summarizes the pathogenesis of mitochondrial autophagy and ferroptosis in PCOS, and analyzes the interrelationship between mitochondrial autophagy and ferroptosis in granulosa cells, in order to provide new insights and potential therapeutic targets for the clinical treatment of PCOS.

Acute respiratory distress syndrome(ARDS)is a common respiratory emergency,but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures.Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS,but the application of hydrogen has flammable and explosive safety concerns.Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance,thus improving ARDS in patients and animal models.Coral calcium hydrogenation(CCH)is a new solid molecular hydrogen carrier prepared from coral calcium(CC).Whether and how CCH affects acute lung injury in ARDS re-mains unstudied.In this study,we observed the therapeutic effect of CCH on lipopolysaccharide(LPS)induced acute lung injury in ARDS mice.The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable,demonstrating a significant improvement compared to the untreated ARDS model group.CCH treatment significantly reduced pulmonary hemorrhage and edema,and improved pulmonary function and local microcirculation in ARDS mice.CCH promoted mitochon-drial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2(Trx2),improved lung mitochondrial dysfunction induced by LPS,and reduced oxidative stress damage.The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.

Objective To analyze the association between eye-related behaviors and myopia among preschool chil-dren in Ningxia Hui Autonomous Region,and to develop a predictive nomogram model.Methods Using stratified cluster random sampling,36 062 preschool children from 400 randomly selected kindergartens in Ningxia Hui Autonomous Region were enrolled between October and December 2023.Primary caregivers of participants completed structured question-naires.Data were randomly split into a training set(n=25 243,70％)and a validation set(n=10 819,30％)in a ratio of 7∶3.The training set was used for model construction,and the validation set for external validation.Calibration plots and the Hosmer-Lemeshow(H-L)goodness-of-fit test assessed agreement between predicted and observed risks.Decision curve analysis(DCA)and clinical impact curve analysis(CICA)evaluated clinical utility.Results The myopia preva-lence among preschool children in Ningxia Hui Autonomous Region was 3.8％.A nomogram model based on binary Logistic regression showed area under the curve(AUC)values of 0.88(95％CI:0.87-0.89)for the training set and 0.89(95％CI:0.87-0.90)for the validation set,indicating strong discriminative ability.Calibration curves and H-L tests revealed good model fit(training set:x2=4.92,P=0.766;validation set:x2=5.52,P=0.961),with all P＞0.05.DCA and CICA confirmed clinical utility.The nomogram identified parental myopia,academic pressure,frequency of eye fatigue,daily screen time,and regular vision checks as the top five predictors of myopia.Conclusion The nomogram demonstrates promising potential for predicting myopia risk in preschool children in Ningxia Hui Autonomous Region,serving as a robust tool for clinical and educational myopia risk assessment.

Objective To analyze the distribution characteristics of 13 common respiratory pathogens in children in Zibo area from 2020 to 2022.Methods A total of 3091 hospitalized children with respiratory infections admitted to Zibo Maternal and Child Health Hospital from January 2020 to December 2022 were selected as the subjects.Throat swabs or bronchoalveolar lavage fluid samples were collected from the patients,and 13 common respiratory pathogens were tested to analyze the distribution differences among different genders,ages,and seasons.Results Among 3091 pediatric patients,1794 were found to be infected with pathogens.The top three pathogens were Mycoplasma pneumoniae,rhinovirus,and respiratory syncytial virus(RSV).The single infection rate was 47.75％,while the mixed infection rate was 10.28％,with the most common scenario being a mixed infection of two pathogens.There were statistically significant differences in the pathogen profiles across different age groups(P＜0.001):infants had the highest detection rate of RSV,young children were primarily infected with rhinovirus,preschool and school-age children were predominantly infected with Mycoplasma pneumoniae.Seasonal distribution showed that the highest positive rate was in autumn,while the lowest was in spring(P＜0.05).In spring,the main pathogens were rhinovirus and Mycoplasma pneumoniae;in summer,they were rhinovirus and parainfluenza virus;in autumn,they were Mycoplasma pneumoniae and RSV;and in winter,the detection rates of Mycoplasma pneumoniae and influenza B virus were higher.Conclusion From 2020 to 2022,Mycoplasma pneumoniae,rhinovirus and RSV were the main pathogens of children's respiratory tract infection in Zibo area,and there were significant differences in the distribution of pathogens among different ages and seasons.
