This paper systematically reviews the core concepts and lines of theoretical inheritance of major spleen-stomach theories in traditional Chinese medicine （TCM）， including spleen deficiency theory， spleen-stomach damp-heat theory， and liver-spleen disharmony theory. It is found that these theories have all undergone a developmental trajectory characterized by classical foundation， refinement of therapeutic methods， systematization of pathogenesis， and modern innovation. The evolution of spleen-stomach theory has achieved a shift from a singular focus on tonifying the spleen to regulating dynamic middle-jiao （焦） balance， and from localized spleen-stomach regulation to the circular movement of qi involving all five zang organs. In terms of modern disease-syndrome integrative research， spleen deficiency syndrome is shown to be closely associated with impairment of the gastrointestinal mucosal barrier， metabolic disorders， and gene polymorphisms related to Helicobacter pylori-associated gastric diseases. Spleen-stomach damp-heat syndrome is closely linked to hyperactive energy metabolism， inflammatory cytokines， and abnormal expression of aquaporins. Liver-spleen disharmony syndrome is mainly associated with dysregulation of the brain-gut axis and microbiota-related metabolic disorders. It is proposed that future research on spleen-stomach diseases and syndromes should further elucidate their potential multidimensional differential biological characteristics， thereby promoting the modernization of the TCM discipline of spleen-stomach studies.

Brain metastases are the most common intracranial tumors, and their incidence is increasing with the improvement of systemic treatments and survival rates. Optimal treatment usually requires a multidisciplinary approach, including radiotherapy, surgical resection, chemotherapy, targeted therapy, and immunotherapy. Stereotactic radiotherapy, compared to whole-brain radiotherapy, offers improved local control rates and reduced risk of neurocognitive impairment, and has become a new standard option for the treatment of brain metastases. Additionally, the widespread use of targeted and immune therapies in brain metastases has significantly improved the survival of some patients. This article reviews and integrates recent literature on the treatment of brain metastases and analyzes the role of stereotactic radiotherapy in comprehensive treatment, aiming to provide a reference for the selection of clinical treatment plans.

Sleep deprivation (SD) has emerged as a significant modifiable risk factor for Alzheimer’s disease (AD), with mounting evidence demonstrating its multifaceted role in accelerating AD pathogenesis through diverse molecular, cellular, and systemic mechanisms. SD is refined within the broader spectrum of sleep-wake and circadian disruption, emphasizing that both acute total sleep loss and chronic sleep restriction destabilize the homeostatic and circadian processes governing glymphatic clearance of neurotoxic proteins. During normal sleep, concentrations of interstitial Aβ and tau fall as cerebrospinal fluid oscillations flush extracellular waste; SD abolishes this rhythm, causing overnight rises in soluble Aβ and tau species in rodent hippocampus and human CSF. Orexinergic neurons sustain arousal, and become hyperactive under SD, further delaying sleep onset and amplifying Aβ production. At the molecular level, SD disrupts Aβ homeostasis through multiple converging pathways, including enhanced production via beta-site APP cleaving enzyme 1 (BACE1) upregulation, coupled with impaired clearance mechanisms involving the glymphatic system dysfunction and reduced Aβ-degrading enzymes (neprilysin and insulin-degrading enzyme). Cellular and histological analyses revealed that these proteinopathies are significantly exacerbated by SD-induced neuroinflammatory cascades characterized by microglial overactivation, astrocyte reactivity, and sustained elevation of pro-inflammatory cytokines (IL-1β, TNF-α, IL-6) through NF‑κB signaling and NLRP3 inflammasome activation, creating a self-perpetuating cycle of neurotoxicity. The synaptic and neuronal consequences of chronic SD are particularly profound and potentially irreversible, featuring reduced expression of critical synaptic markers (PSD95, synaptophysin), impaired long-term potentiation (LTP), dendritic spine loss, and diminished neurotrophic support, especially brain-derived neurotrophic factor (BDNF) depletion, which collectively contribute to progressive cognitive decline and memory deficits. Mechanistic investigations identify three core pathways through which SD exerts its neurodegenerative effects: circadian rhythm disruption via BMAL1 suppression, orexin system hyperactivity leading to sustained wakefulness and metabolic stress, and oxidative stress accumulation through mitochondrial dysfunction and reactive oxygen species overproduction. The review critically evaluates promising therapeutic interventions including pharmacological approaches (melatonin, dual orexin receptor antagonists), metabolic strategies (ketogenic diets, and Mediterranean diets rich in omega-3 fatty acids), lifestyle modifications (targeted exercise regimens, cognitive behavioral therapy for insomnia), and emerging technologies (non-invasive photobiomodulation, transcranial magnetic stimulation). Current research limitations include insufficient understanding of dose-response relationships between SD duration/intensity and AD pathology progression, lack of long-term longitudinal clinical data in genetically vulnerable populations (particularly APOE ε4 carriers and those with familial AD mutations), the absence of standardized SD protocols across experimental models that accurately mimic human chronic sleep restriction patterns, and limited investigation of sex differences in SD-induced AD risk. The accumulated evidence underscores the importance of addressing sleep disturbances as part of multimodal AD prevention strategies and highlights the urgent need for clinical trials evaluating sleep-focused interventions in at-risk populations. The review proposes future directions focused on translating mechanistic insights into precision medicine approaches, emphasizing the need for biomarkers to identify SD-vulnerable individuals, chronotherapeutic strategies aligned with circadian biology, and multi-omics integration across sleep, proteostasis and immune profiles may delineate precision-medicine strategies for at-risk populations. By systematically examining these critical connections, this analysis positions sleep quality optimization as a viable strategy for AD prevention and early intervention while providing a comprehensive roadmap for future mechanistic and interventional research in this rapidly evolving field.

Objective To explore the relationship between community health follow-up management and the mental health of the long-term care insurance residents,and to provide a basis for the construction of an integrated community home care service mode for disabled elders.Methods The residents were selected through cluster sampling who participated in LTCI home care from Jan 1 to Dec 31,2021.After a year of participation,the subjects'mental health was assessed face-to-face by trained community doctors using the Self-Rating Anxiety Scale and the Self-Rating Depression Scale.By referring to residents'electronic health records combined with on-site questionnaire survey,community doctors collected the demographic information and health follow-up management provided by primary medical and health institutions.The multivariate logistic regression were conducted to evaluate the association between follow-up care and mental health outcomes.Results The study consisted of 399 LTCI-enrolled individuals,57.64%(n=230)received follow-up care by family physicians.The prevalence of anxiety and depression among participants was 19.80%(n=79)and 67.67%(n=270),respectively.Univariate analysis found that community health follow-up management could underscore the potential impact of follow-up care in mitigating anxiety(χ2=38.926,P<0.001)and depression(χ2=14.598,P<0.001)among LTCI enrollees.Multivariate analysis revealed that follow-up care was an independent protective factor against anxiety(adjusted OR=0.351,95%CI:0.176-0.701,P=0.003).However,follow-up care did not significantly impact depression prevalence.Additionally,LTCI grade and education level were also identified factors influencing the mental health of participants(P<0.05).Conclusion Community health service centers provide health follow-up management that plays a positive role in alleviating the anxiety symptoms of disabled residents under long-term care insurance home care.It is an effective way to improve the quality of LTCI home care services.

This study aims to investigate the effects of aerobic exercise on neuroinflammation in AD mice and explore the mechanisms of neuroinflammation regulated by the blood-brain barrier,lipopolysaccharide(LPS)displacement,and glial cell activation.Twenty 3-month-old male APP/PS1 double transgenic mice were used,which were randomly divided into a sedentary group(SE-AD)and an aerobic exercise group(Run-AD),and 10 3-month-old male C57BL/6 mice were used as the control group(WT).The Run-AD group underwent 12 weeks of aerobic training.The results of the water maze showed that aerobic exercise improved the learning and memory capacity of AD mice(P＜0.05).The results of H&E stai-ning and Nissl staining showed that aerobic exercise reduced necrotic cells and inflammatory cell infiltra-tion in the cerebral cortex,as well as nuclear condensation in the CA1 and GD regions of the hippocam-pus(P＜0.05,P＜0.01),and increased the area of Nissl bodies in the cerebral cortex and hippocam-pal CA3 and DG regions.Western blotting and ELISA results showed that aerobic exercise increased the expression of Occludin,ZO-1 and Claudin-5 proteins in the brain(P＜0.01),and decreased the levels of LPS in the brain(P＜0.01).The qRT-PCR results exhibited that aerobic exercise decreased the ex-pression of TLR4,MyD88,NF-κB,IL-1β,and TNF-α mRNA(P＜0.05,P＜0.01).The results of immunofluorescence staining revealed that aerobic exercise reduced the fluorescence area of brain IL-1βand TNF-α proteins(P＜0.05,P＜0.01),as well as the fluorescence area of Iba-1,GFAP,and TLR4 proteins in the cerebral cortex and hippocampus(P＜0.05,P＜0.01).There was a high degree of overlap between Iba-1 and TLR4 fluorescence in the cerebral cortex,and GFAP was localized around Iba-1.In summary,aerobic exercise attenuates neuroinflammation in AD mice by protecting the blood-brain barrier,reducing the displacement of LPS,and subsequently weakening the immune activation of microglia to regulate the TLR4/MyD88/NF-κB signaling pathway to alleviate neuroinflammation.

Objective:To analyze the vulvovaginal microecological characteristics of young girls and the impact of age on these characteristics.Methods:A total of 371 young girls aged≤12 years who visited the department of Gynecological,Peking University First Hospital from January 2016 to December 2022 were selected.These girls were stratified into three age groups:＜7 years,7-9 years,and＞9-12 years.Then,the results of their vulvovagi-nal microecology were analyzed.Results:A total of 84 cases(22.6％)were clinically diagnosed with vulvovagini-tis,including 43 cases(43/84,51.2％)of bacterial vaginosis(BV),38 cases(38/84,45.2％)of vulvovaginal can-didiasis(VVC),2 cases(2/84,2.4％)of trichomoniasis vaginalis(TV),and 1 case(1/84,1.2％)of mixed vul-vovaginitis(BV+VVC).It was found that there was a statistically significant difference in VVC infection among different age groups of young girls(P＜0.001),and the infection rate was higher in the＞9-12 years group.Sig-nificant variations were also observed in BV infection among different age groups of young girls(P＜0.001).The infection rate was the highest in the 7-9 years group and the lowest in the＞9-12 years group.Among the 371 patients,165 cases(44.5％)had normal vaginal flora,176 cases(47.4％)had abnormal vaginal flora.Among them,64 cases(17.3％)had BV-type abnormal flora,and 112 cases(30.2％)had non-BV-type abnormal flora.There were 30 cases(8.1％)with flora suppression.The composition ratios of flora suppression,BV-type abnor-mal flora,non-BV-type abnormal flora,and total abnormal flora demonstrated statistically significant intergroup var-iations across age cohorts(P＜0.001).Microecological analysis showed that there were statistically significant differences in the composition ratios of factors such as dominant bacteria(Gram-positive large bacilli)and pH a-mong different age groups(P＜0.001).Conclusions:The composition of the vulvovaginal microecology varies a-mong young girls of different ages,and differences exist in reproductive tract infections across these age groups.Assisting in diagnosis through vulvovaginal microecology can better guide clinicians to provide targeted treatment for reproductive tract infections in young girls,and improve the clinical cure rates.

Objective:To analyze the incidence of pregnancy complications and maternal-neonatal outcomes in women with a history of preconception metabolic and bariatric surgery (MBS).Methods:This study was a retrospective cohort study. Pregnant women with singleton pregnancy who delivered in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School, from September 2019 to December 2024 were selected as the observation subjects. After propensity score matching, 42 women in the MBS group and 157 women in the control group were finally included. The general clinical characteristics, pregnancy status and maternal-neonatal outcomes of the two groups were compared and analyzed.Results:(1) There were no statistically significant differences in the age, proportion of preconception obesity, chronic hypertension, preconception diabetes and primipara between the MBS group and the control group (all P>0.05). The median interval between surgery and pregnancy of pregnant women in the MBS group was 14.0 months (6.0, 27.5 months). Twenty-nine pregnant women (69%, 29/42) were pregnant after 1 year of surgery, and 13 pregnant women (31%, 13/42) were pregnant within 1 year. (2) The levels of hemoglobin, serum iron and triglyceride in the MBS group were significantly lower than those in the control group in the second and third trimester (all P<0.05), but there were no statistically significant differences in the levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total cholesterol and albumin between the two groups (all P>0.05). (3) Compared with the control group, the incidence of gestational diabetes mellitus in MBS group [21.7% (34/157) vs 7.1% (3/42)] and the proportion of large for gestational age [23.6% (37/157) vs 2.4% (1/42)] were lower; the incidence of anemia [6.4% (10/157) vs 33.3% (14/42)], fetal growth restriction [7.0% (11/157) vs 23.8% (10/42)] and small for gestational age [3.8% (6/157) vs 19.0% (8/42)] were higher; the differences were statistically significant (all P<0.05). There were no significant differences in the cesarean section rate, premature rupture of membranes rate, postpartum hemorrhage ≥1 000 ml rate, gestational age at delivery and preterm birth rate between the two groups (all P>0.05). The neonatal birth weight of the MBS group was significantly lower than that of the control group [(3 044±523) vs (3 256±491) g, P=0.016], but the proportion of neonates with 1-minute Apgar score<7 and the rate of neonatal intensive care unit admission were not statistically significant (all P>0.05). Conclusions:Women who got pregnant after MBS had lower neonatal weight, decreased incidence of gestational diabetes mellitus and large for gestational age, but higher incidence of small for gestational age and anemia in late pregnancy. It is necessary to focus on the nutritional management of pregnant women with MBS before pregnancy, improve anemia, and strengthen the ultrasound follow-up of fetal growth to optimize the perinatal outcome.
