ObjectiveTo investigate the migration and distribution characteristics of chemical constituents in blood and hippocampal tissues before and after vinegar processing of Citri Reticulatae Pericarpium Viride（CRPV）， and to explore the potential material basis and mechanisms underlying their regulatory effects on emotional disorders by comparing the effects of raw and vinegar-processed products of CRPV. MethodsUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was employed to characterize and identify the chemical constituents of raw and vinegar-processed products of CRPV extracts， as well as their migrating components in blood and hippocampal tissues after oral administration. Reference standards， databases， and relevant literature were utilized for compound annotation， with data processing performed using PeakView 1.2 software. Seventy male C57BL/6 mice were randomly divided into seven groups， including the blank group， model group， diazepam group（2.5 mg·kg^-1）， raw CRPV low/high dose groups（0.6， 1.2 g·kg^-1）， and vinegar-processed CRPV low/high dose groups（0.6， 1.2 g·kg^-1）， with 10 mice per group. Except for the blank group， all other groups underwent chronic restraint stress（2 h·d^-1） for 20 d. Each drug-treated group received oral administration at the predetermined dose starting 10 d after modeling， with a total treatment duration of 10 d. Following model-based drug administration， mice underwent open-field， forced swimming， and elevated plus maze tests. After anesthesia with isoflurane， whole brains were collected from each group of mice， and hippocampi were dissected. Reactive oxygen species（ROS） level in hippocampal tissues was quantified by enzyme-linked immunosorbent assay（ELISA）. Hematoxylin-eosin（HE） staining was used to observe hippocampal tissue morphology. Immunofluorescence was performed to detect neuronal nuclei（NeuN） and peroxisome proliferator-activated receptor alpha（PPARα） expressions in hippocampal tissue. Then， pharmacodynamic evaluations were conducted to assess the effects of raw and vinegar-processed CRPV on mood disorders， exploring the potential mechanisms. ResultsVinegar processing caused significant changes in the chemical composition of CRPV， with 18 components showing increased relative content and 35 components showing decreased relative content. The primary changes occurred in flavonoid compounds， including 20 flavonoids， 20 flavonoid glycosides， 3 triterpenes， 3 phenolic acids， 1 alkaloid， and 6 other compounds. Twenty-one components were detected in blood（15 methoxyflavones， 4 flavonoid glycosides， and 2 phenolic acids）， with 17 shared between raw and vinegar-processed CRPV. Seven components reached hippocampal tissues（all common to both forms）. In regulating emotional disorders， Vinegar-processed CRPV exhibited superior antidepressant-like effects compared to raw products. HE staining revealed that both treatments improved hippocampal neuronal morphology， particularly in the damaged CA1 and CA3 regions. Immunofluorescence and ELISA analyses demonstrated that both raw and vinegar-processed CRPV significantly modulated NeuN and PPARα expressions in hippocampal tissue while alleviating oxidative stress induced by excessive ROS（P<0.05）. ConclusionThe chemical composition of CRPV undergoes changes after vinegar processing， but the migrating components in blood and hippocampus are primarily methoxyflavonoids. These components may serve as the potential material basis for activating the PPARα pathway， thereby negatively regulating ROS generation in the hippocampus， reducing oxidative stress， and promoting the development of NeuN-positive neurons. These findings provide experimental evidence for enhancing quality standards， pharmacodynamic material research， and active drug development of raw and vinegar-processed CRPV.

Objective: To explore the association of vegetables and fruits intake with depressive symptoms among multi ethnic first year junior high school students in Yunnan Province, so as to provide data support for preventing and reducing depressive symptoms among first year junior high school students. Methods: From October to December 2022, a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas in Yunnan Province (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County), to investigate with a questionnaire. The Dietary Frequency Questionnaire was used to collect dietary behavior datas, and the Chinese version of Depression Anxiety Stress Scale-21 (DASS-21) was used to assess depressive symptoms. The generalized linear model was used to analyze the association of vegetable and fruit intake with depressive symptoms in students, and stratified analysis was performed according to ethnicity. Results: The detection rate of depressive symptoms among first year junior high school students in Yunnan Province was 29.5%. The detection rates of depressive symptoms in Han and minority first year junior high school students were 26.9% and 31.6%. After controlling for demographic variables such as gender, age, family residence and other confounding factors, the generalized linear model analysis results showed that the intake of leafy vegetables ( β= -0.07 , 95%CI =-0.12 to -0.01), flat fruits ( β=-0.06, 95%CI =-0.12 to -0.00) and hot natured fruits ( β=0.11, 95%CI = 0.04- 0.17) were associated with depressive symptoms in Han first year junior high school students (all P <0.05). The intake of melon and fruit vegetables ( β=-0.06, 95%CI =-0.11 to -0.01) and hot natured fruits ( β=0.06, 95%CI =0.01-0.12) were associated with depressive symptoms in ethnic minority first year junior high school students (both P <0.05). Conclusions The intake of vegetables and fruits among multi ethnic first year junior high school students in Yunnan Province is related to the risk of depressive symptoms. It is suggested to strengthen the consumption guidance and education of vegetables and fruits to prevent depressive symptoms among first year junior high school students.

Systemic lupus erythematosus （SLE）， a refractory autoimmune disease， is among the dominant diseases where traditional Chinese medicine （TCM） shows advantages in the field of rheumatology and immunology. The China-Japan Friendship Hospital hosted the "46^th Youth Salon on Dominant Diseases （Systemic Lupus Erythematosus）" organized by the China Association of Chinese Medicine， which led to a consensus on "the advantages， challenges， interdisciplinary approaches， and translational achievements of integrated TCM and Western medical approaches in the diagnosis and treatment of SLE." The diagnosis and treatment of SLE currently face several challenges， such as frequent misdiagnosis and missed diagnosis in the early stages， difficulty in achieving treatment targets， multiple side effects from pharmacotherapy， and the lack of management strategies for special populations， all of which hinder the fulfillment of the clinical needs of patients. Integrated TCM and Western medical approaches can improve clinical symptoms such as skin erythema， aversion to cold and cold limbs， fatigue， dry mouth， restlessness， and heat sensation in the palms and soles， thereby improving patients' quality of life. The approaches also help consolidate the efficacy of conventional Western medicine， slow disease progression， reduce relapse rates， address multi-organ involvement， and prevent or treat complications. Additionally， they enhance efficacy and reduce toxicity， prevent the side effects of Western medications， help reduce hormone use， and offer distinct advantages in the individualized intervention of special populations， contributing to the whole-process management of the disease. However， evidence-based medical support for this integrated approach remains limited， and the quality of available evidence is generally low. Common evaluation systems and modern research methodologies should be adopted to clarify the efficacy of TCM in SLE treatment. Efforts should be made to carry out high-quality evidence-based medical research， strengthen the development of fundamental and pharmacological research， and further explain the distinct advantages of TCM in the diagnosis and treatment of SLE. Future efforts should focus on advancing the integration of TCM and modern medicine， incorporating multi-omics technologies， individualized stratification， and other precision medicine concepts， in combination with artificial intelligence. Moreover， interdisciplinary collaboration should be promoted to utilize modern technology in exploring the essence of TCM theories and screening effective formulae， thereby comprehensively improving the diagnosis and treatment of SLE through integrated TCM and Western medical approaches.

Rheumatoid arthritis （RA） is an autoimmune disease characterized primarily by erosive arthritis， with a high prevalence and disability rate. Although significant progress has been made in the treatment of RA in recent years， challenges such as suboptimal efficacy， drug resistance， severe side effects， and high costs of long-term treatment remain， especially for patients in the early stages of RA， as well as those with RA complications， comorbidities， and severe conditions. Hosted by the China-Japan Friendship Hospital and organized by the Youth Committee of the China Association of Chinese Medicine， the 27^th session of the Clinical Dominant Disease Series （Rheumatoid Arthritis） Youth Salon invited nearly 20 experts and scholars from traditional Chinese medicine （TCM）， western medicine， and interdisciplinary fields to actively discuss the clinical needs of modern medicine and the advantageous stages and aspects of TCM in RA. Experts at the salon agreed that TCM has unique advantages in the treatment of RA， especially during the early stage， periods of low to moderate disease activity， remission phase， and in addressing complications and comorbidities. TCM can achieve both prevention and treatment by regulating the immune system and restoring immune homeostasis. The integrated approach of traditional Chinese and western medicine demonstrates significant advantages in active RA， refractory cases， and stages with severe complications， by rapidly controlling disease progression， alleviating symptoms， enhancing the quality of life， and facilitating recovery. Given the frequent occurrence of multiple comorbidities in RA， TCM shows potential in regulating immunity， alleviating symptoms， and improving physical constitution， which provides new insights into the comprehensive treatment of RA with comorbidities. However， high-quality clinical studies on integrated traditional Chinese and western medicine in RA are still lacking. It is necessary to establish large-scale clinical cohorts and biological databases to provide a scientific basis for the development of precision-targeted therapies and clinical treatment protocols. In the future， individualized treatment strategies integrating traditional Chinese and western medicine are expected to become an important direction for improving the quality of life in RA patients.

Mitochondrial dysfunction is a critical factor in the pathogenesis of Alzheimer's disease (AD). The mitochondrial contact site and cristae organizing system (MICOS) plays a pivotal role in shaping the inner mitochondrial membrane, forming cristae junctions and establishing interaction sites between the inner and outer mitochondrial membranes and thereby serving as a cornerstone of mitochondrial structure and function. In the past decade, MICOS abnormalities have been extensively linked to AD pathogenesis. In particular, dysregulated expression of MICOS subunits and mutations in MICOS-related genes have been identified in AD, often in association with hallmark pathological features such as amyloid-β plaque accumulation, neurofibrillary tangle formation, and neuronal apoptosis. Furthermore, MICOS subunits interact with several etiologically relevant proteins, significantly influencing AD progression. The intricate crosstalk between these proteins and MICOS subunits underscores the relevance of MICOS dysfunction in AD. Therapeutic strategies targeting MICOS subunits or their interacting proteins may offer novel approaches for AD treatment. In the present review, we introduce current understanding of MICOS structures and functions, highlight MICOS pathogenesis in AD, and summarize the available MICOS-targeting drugs potentially useful for AD.

Objective:To investigate the effects of long non coding RNA KCNQ1OT1(LncRNA KCNQ1OT1)on the migration and invasion of oral squamous cell carcinoma(OSCC)cells by regulating the microRNA-875-5p(miR-875-5p)/ETS like transcription factor 4(ELK4)axis.Methods:QRT-PCR was applied to detect the mRNA levels of LncRNA KCNQ1OT1,miR-875-5p,and ELK4 in OSCC cell lines(HSC-3,PE/CA-PJ15,HN13)and tissues.The dual luciferase assay was applied to detect the targeting relationship between LncRNA KCNQ1OT1 and miR-875-5p,and target relationship between miR-875-5p and ELK4.HSC-3 cells were used in control group,sh-NC group,sh-KCNQ1OT1 group,sh-KCNQ1OT1+anti-NC group,sh-KCNQ1OT1+anti-miR-875-5p group,miR-NC group,miR-875-5p mimic group,miR-875-5p mimic+pcDNA-NC group,and miR-875-5p mimic+ELK4 group.The migration and invasion abilities of HSC-3 cells were detected.Immunoblotting was applied to detect the protein expression of ELK4,MMP-2,MMP-9 and epithelial mesenchymal transition(EMT)(E-Cadherin,N-Cadherin,Vimentin).The nude mouse transplant tumor was applied to verify the effect of LncRNA KCNQ1OT1 on OSCC transplant tumors.Results:LncRNA KCNQ1OT1 and ELK4 mRNA expression increased in OSCC tissues and cancer cell lines,while miR-875-5p expression decreased(P＜0.05).Database predictions show that miR-875-5p specifically bound to LncRNAs KCNQ1OT1 and ELK4,respectively.Compared with the sh-NC group,the numbers of cell migration and cell invasion,the expression of LncRNA KCNQ1OT1,ELK4,MMP-2,MMP-9,N-Cadherin,and Vimentin in the sh-KC-NQ1OT1 group were lower,while the expression of miR-875-5p and E-Cadherin was higher(P＜0.05).Compared with the sh-KC-NQ1OT1+anti-NC group,the expression of miR-875-5p and E-Cadherin in the sh-KCNQ1OT1+anti-miR-875-5p group was lower,while the numbers of cell migration and cell invasion,the expression of ELK4,MMP-2,MMP-9,N-Cadherin,and Vimentin were higher(P＜0.05).Compared with the miR-NC group,the expression of miR-875-5p and E-Cadherin in the miR-875-5p mimic group was higher,while the numbers of cell migration and cell invasion,the expression of ELK4,MMP-2,MMP-9,N-Cadherin,and Vim-entin were lower(P＜0.05).Compared with the miR-875-5p mimic+pcDNA-NC group,the numbers of cell migration and cell inva-sion,the expression of ELK4,MMP-2,MMP-9,N-Cadherin,and Vimentin in the miR-875-5p mimic+ELK4 group were higher,while the expression of E-Cadherin was lower(P＜0.05).The transplant tumor volume and weight of the sh-KCNQ1OT1 group were smaller than those of the sh-NC group,the mRNA and protein expression levels of LncRNA KCNQ1OT1,ELK4 were lower than those of the sh-NC group,and the expression level of miR-875-5p was higher than that of the sh-NC group(P＜0.05).Conclusion:Inhibition of LncRNA KCNQ1OT1 can target the miR-875-5p/ELK4 axis to inhibit migration,invasion,and EMT of OSCC cells.

Objective:To investigate the efficacy of blepharoplasty using the "double-line technique" in addressing upper eyelid skin laxity in middle-aged and elderly patients.Methods:A retrospective analysis was conducted on the clinical data of middle-aged and elderly patients with moderate to severe upper eyelid skin laxity who were admitted to the Plastic Surgery Department of Shaanxi Provincial People’s Hospital between January 2020 and January 2023. The same surgeon performed the "double-line" blepharoplasty to excise excess upper eyelid skin for laxity correction. Patients were positioned flat with their eyes closed; an arcuate line a (5-7 mm above the pupil) and a second line b (aligned with the eyelid margin in an upright position) were marked. The skin between these two lines was excised. Postoperatively, the double eyelid shape, improvement in skin laxity, adverse reactions, and patient satisfaction (categorized as satisfied, basically satisfied, unsatisfied) were assessed.Results:A total of 145 patients were included in the study, comprising 27 males and 118 females. Their ages ranged from 38 to 78 years, with an average age of 52 years. All patients’ incisions healed primarily without complications such as hematoma and infection. During the 3 to 12 months of follow-up after surgery, the double eyelid arcs on both sides appeared symmetrical and natural. The upper eyelid laxity was effectively corrected, obscured vision was improved, crow’s feet were reduced, and the periorbital area was rejuvenated. Patient satisfaction with the surgical results was high, with 112 patients reporting satisfaction, 25 reporting basically satisfied, and 8 reporting dissatisfaction. The overall satisfaction rate reached 94.48%(137/145). Among those dissatisfied, 6 cases cited the double eyelid crease as being too narrow, and 2 cases noted asymmetry in the double eyelid crease.Conclusion:The "double-line method" for blepharoplasty is straightforward to perform and effectively removes excess upper eyelid skin. It is suitable for middle-aged and elderly patients with moderate to severe upper eyelid skin laxity, resulting in favorable surgical outcomes.

Objective:To compare the efficacy of whole blood (WB) versus component therapy (COMP) in the resuscitation of patients with traumatic shock.Methods:A systematic literature search was conducted using PubMed and Embase databases for English literature published from January 2006 to December 2023. Studies on the comparative efficacy of WB versus COMP in resuscitation of patients with traumatic shock were all included. Patients were categorized according to the initial transfusion strategies into WB group and COMP group. Primary outcome indicators were extracted and subjected to meta-analysis, including transfusion requirements after admission (4-hour red blood cell requirement, 4-hour plasma requirement, 4-hour total transfusion volume, 24-hour red blood cell requirement, 24-hour plasma requirement, and 24-hour total transfusion volume), length of hospital stay, length of ICU stay, and mortality rates (early mortality, 24-hour mortality, late mortality, and in-hospital mortality, and 24-hour mortality with multiple variables adjusted).Results:Twenty-seven studies involving 15 176 patients (4 692 patients in WB group and 10 484 in COMP group) were included. Meta-analysis results indicated that the 4-hour red blood cell requirement (SMD=-0.44, 95% CI -0.69, -0.19, P<0.01), 4-hour plasma requirement (SMD=-0.25, 95% CI -0.50, -0.01, P<0.05), 24-hour red blood cell requirement (SMD=-0.22, 95% CI -0.36, -0.09, P<0.01), and 24-hour mortality with multiple variables adjusted ( OR=0.78, 95% CI 0.68, 0.91, P<0.05) were significantly reduced in WB group. No significant differences were observed between the two groups regarding 4-hour total transfusion volume, 24-hour plasma requirement, 24-hour total transfusion volume, length of hospital stay, length of ICU stay, early mortality, 24-hour mortality, late mortality, and total in-hospital mortality ( P>0.05). Conclusions:WB demonstrates certain advantages over COMP in the resuscitation of patients with traumatic shock by reducing 4-hour red blood cell requirement, 4-hour plasma requirement, 24-hour red blood cell requirement, and 24-hour mortality with multiple variables adjusted. However, WB and COMP demonstrate comparable effectiveness in reducing 4-hour total transfusion volume, 24-hour plasma requirement, 24-hour total transfusion volume, early mortality rate, 24-hour mortality rate, late mortality rate, and in-hospital mortality.
