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.

Objective To design melatonin(Mel)-based nanomedicines(Mel-NMs)and evaluate their therapeutic effects on myocardial ischemia-reperfusion injury in mice.Methods Melatonin self-assembled peptides(Mel-NMs)were synthesized and their structure was characterized by transmission electron microscopy.Mice were divided randomly into five groups:Sham,Model,Mel,NMs,and Mel-NMs,and a myocardial ischemia-reperfusion injury model was established.Mel(5 mg/kg),NMs,or Mel-NMs(containing Mel 5 mg/kg)were administered intraperitoneally 10 minutes prior to reperfusion,and the sham group was treated with an equal volume of solvent.Cardiac function,apoptosis,and oxidative stress markers were assessed 24 hours after reperfusion.Results Transmission electron microscopy revealed that Mel-NMs formed worm-like structures.Treatment with Mel and Mel-NMs significantly improved cardiac function,reduced lactate dehydrogenase and malondialdehyde levels,and enhanced glutathione peroxidase and superoxide dismutase activities(P＜0.05),while also decreasing cardiomyocyte apoptosis(P＜0.05),with greater effects in the Mel-NMs group(P＜0.05).Conclusions Mel-NMs can effectively mitigate myocardial oxidative stress and apoptosis,offering a more potent cardioprotective effect than Mel alone.

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 preliminarily explore therapeutic effects and possible molecular mechanisms of sinomenine on atopic dermatitis (AD) -like mouse models.Methods:Thirty female BALB/c mice (6 - 8 weeks old) were randomly divided into 5 groups: blank control group, model group, positive control group, topical sinomenine group, and oral sinomenine group. Except for the blank control group, all groups were subjected to repeated topical stimulation with 2,4-dinitrochlorobenzene (DNCB) on the dorsal skin to establish an AD-like mouse model. After modeling, no special treatment was given to the blank control group, the positive control group was topically treated with 100 μg of 0.1% mometasone furoate cream twice daily on the lesions, the topical sinomenine group was topically treated with 100 μl of 10 mg/ml sinomenine solution twice daily on the lesions, and the oral sinomenine group was gavaged with sinomenine solution at a dose of 100 mg·kg -1·d -1 (100 μl per dose, twice daily) . Treatments lasted for 14 days. Twelve hours after the final treatment, the severity of skin lesions in each group was assessed. Blood samples were collected via enucleation, and serum levels of interleukin (IL) -1β, IL-6, and immunoglobulin E (IgE) were measured using enzyme-linked immunosorbent assay (ELISA) . Histopathological changes in dorsal skin lesions were observed, and immunohistochemical study was performed to detect the expression levels of p38 mitogen-activated protein kinase (MAPK) and nuclear factor (NF) -κB p65 in skin tissues, expressed as the percentage of the immunopositive area. One-way analysis of variance was used for multiple group comparisons, while Tukey′s test or the Games-Howell test was applied for post-hoc comparisons between groups. Results:Compared with the blank control group, the model group exhibited epidermal hyperkeratosis with parakeratosis, thickening of the spinous layer, spongiosis, significant inflammatory cell infiltration, and prominent angiogenesis. In contrast, the positive control group, topical sinomenine group, and oral sinomenine group showed reduced spinous layer thicknesses, decreased inflammatory cell infiltration, and less pronounced angiogenesis compared to the model group. In the blank control group, model group, positive control group, topical sinomenine group, and oral sinomenine group, the severity scores of skin lesions were 0, 8.83 ± 0.75, 4.33 ± 1.08, 2.58 ± 0.49, 2.83 ± 0.93 respectively, the serum levels of IL-1β were 52.58 ± 1.72, 168.40 ± 7.23, 57.07 ± 6.39, 85.74 ± 4.15, 100.30 ± 11.55 pg/ml respectively, IL-6 levels were 86.88 ± 4.60, 215.00 ± 5.02, 79.34 ± 4.91, 127.20 ± 1.06, 149.00 ± 6.21 pg/ml respectively, IgE levels were 2 159.00 ± 176.00, 3 493.00 ± 89.61, 2 294.00 ± 158.10, 2 550.00 ± 214.70, 2 814.00 ± 119.70 μg/ml respectively, the expression levels of p38 MAPK in skin tissues were 3.03% ± 3.38%, 12.95% ± 6.89%, 2.14% ± 1.28%, 5.28% ± 3.71%, 3.85% ± 2.26% respectively, and NF-κB p65 expression levels were 0.61% ± 0.49%, 18.92% ± 6.96%, 3.77% ± 1.90%, 5.66% ± 2.28%, 6.25% ± 3.14% respectively; the differences in all the above parameters were statistically significant among groups (all P < 0.05) . Compared with the blank control group, the model group had significantly increased skin lesion severity scores, serum IL-1β, IL-6, and IgE levels, as well as elevated expression of p38 MAPK and NF-κB p65 in skin tissues (all P < 0.01) . Compared with the model group, the positive control group, topical sinomenine group, and oral sinomenine group showed significantly reduced skin lesion severity scores, decreased serum IL-1β, IL-6, and IgE levels, and lower expression of p38 MAPK and NF-κB p65 in skin tissues (all P < 0.05) . Compared with the positive control group, the topical and oral sinomenine groups exhibited further reductions in skin lesion severity scores (both P < 0.05) . Additionally, the topical sinomenine group showed significantly lower serum levels of IL-1β and IL-6 compared with the oral sinomenine group (both P < 0.05) . Conclusion:Sinomenine solution could obviously alleviate the severity of skin lesions in AD-like mouse models, likely by down-regulating the expression of IL-1β, IL-6 and IgE, inhibiting the MAPK/NF-κB signaling pathway, and thus reducing the degree of inflammation.

The clinical characteristics of a neonatal patient with movement disorder and arthrogryposis (NDEEMA) caused by gain-of-function mutation of the SCN1A gene were reported in this article. The 1-year-and-9-month-old boy started seizures since 2 hours after birth. He had funnel-breast, dislocation of the hip, and bipedal varus. Genetic testing showed SCN1A gene de novo missense mutation c.706A>G(p.Ile236Val), causing overall gain-of-function effect. The frequency of seizures decreased significantly after treatment of oxcarbazepine.

A total of 27 best evidence items were extracted, covering seven aspects: principles of fluid therapy, preoperative fluid management, intraoperative fluid management, postoperative fluid management, fluid type selection, assessment and monitoring, and training and education.Conclusions:This study summarizes the best evidence on perioperative fluid management for hepatectomy in liver cancer patients and provides an evidence-based reference for clinical nursing practice. Healthcare professionals should apply the evidence in a personalized manner based on the actual clinical context to promote scientific fluid management in the perioperative period.

Polycystic ovary syndrome(PCOS)is a common endocrine disorder closely associated with insulin resistance(IR)and hyperandrogenemia(HA).Oxidative stress has been closely linked to chronic metabolic diseases such as IR and diabetes,and is also considered one of the key factors in the pathogenesis and progression of PCOS.Under physiological conditions,insulin-like growth factor 1(IGF-1)plays a crucial role in regulating cellular proliferation,metabolic processes,and alleviating oxidative stress.However,in PCOS patients,an oxidative stress state is frequently observed,which interacts with IR and HA to stimulate elevated IGF-1 levels.This,in turn,exacerbates oxidative stress and inflammatory responses,ultimately worsening the patholog-ical state of PCOS.This review summarizes the molecular mechanisms underlying the roles of IGF-1 and oxidative stress in the onset and progression of PCOS,aiming to provide new insights into its pathophysiology and potential therapeutic strategies.

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.
