With the aging of the global population， osteoporosis （OP） is becoming a major public health concern worldwide. Currently， the commonly used anti-osteoporosis drugs in clinical practice have limited application due to many side effects. Therefore， developing more effective and safer strategies for the prevention and treatment of OP has become a research focus in this field. In recent years， the clinical efficacy and advantages of traditional Chinese medicine （TCM） in treating OP have been gradually recognized. With the deepening pharmacological research on TCM for OP prevention and treatment， it is found that the active ingredients of Scutellaria baicalensis can promote bone formation or inhibit bone resorption by regulating signaling pathways， including Wnt/β-catenin， osteoprotegerin （OB）/receptor activator of nuclear factor-κB ligand （RANKL）/RANK （OPG/RANKL/RANK）， and bone morphogenetic protein 2 （BMP-2）/Smad， mitogen-activated protein kinase （MAPK）， and mammalian target of rapamycin （mTOR）. However， existing research on active ingredients of S. baicalensis for OP treatment is scattered， making it difficult for scholars to gain a systematic understanding of its research and application. This review summarized the literature on the active ingredients of S. baicalensis in OP treatment worldwide， clarified their mechanisms of action， and explored some issues， providing references for the integration of TCM in OP prevention and treatment.

Objective:To examine the effects of an improved mindfulness-based intervention program(IMIP)on depression,anxiety,psychological resilience,and marital quality among perinatal women.Methods:We enrolled 120 perinatal women receiving care at the obstetrics departments of Pudong Hospital and Nanhui Maternity and Child Health Hospital from December 2022 to August 2024.They were randomly assigned to either routine care group or IMIP group.The routine care group received standard prenatal care,while the IMIP group received,in addition to routine care,an eight-week course of IMIP intervention,administered once a week.Outcome mea-sures included the Edinburgh Postnatal Depression Scale(EPDS),Hospital Anxiety and Depression Scale(HADS),Connor-Davidson Resilience Scale(CD-RISC),and ENRICH Marital Satisfaction Scale,assessed at six time points—before intervention,after interven-tion(at 35 weeks of gestation),and at 3 days,42 days,3 months,and 6 months postpartum.A repeated measures ANOVA was con-ducted,with the score changes(Δ values)at individual time points from baseline as the dependent variable.Results:The IMIP group showed significantly greater improvements than the routine care group in EPDS,HADS-anxiety,CD-RISC,and ENRICH scores,with the main effects of group and time and their interaction effect all being significant(all P<0.001).For HADS-depression,the group×time interaction was not significant,but the main effect of group was significant(P<0.001).CD-RISC and ENRICH scores in-creased with time in the IMIP group.Conclusion:IMIP effectively alleviates depressive and anxiety symptoms,enhances psychological resilience,and improves marital quality for perinatal women,showing strong potential for clinical application.

AIM: To observe related influence of eye-use behaviors on the onset and progression of myopia among primary school student in Minhang district, Shanghai under the background of “double reduction”, and evaluate the impact of eye-use habit and behavior on the myopia development in children and adolescents.METHODS:A stratified cluster sampling method was adopted to select study subjects for longitudinal observation. Random sampling was conducted among grade 1-4 students from three primary schools in Minhang District, Shanghai from September to December 2021 after the implementation of the “double reduction” policy, with a 2-year observation period. Annual vision screenings were performed to obtain uncorrected visual acuity, non-cycloplegic refraction data, and spherical equivalent(SE). Biometric measurements were taken to acquire axial length(AL)and corneal curvature(CR). Questionnaires were administered to investigate the eye-use behaviors of participants. Taking myopia ≤-0.50 D as the diagnostic criterion, myopia incidence were calculated. SE and AL changes were used to evaluate myopia progression. Logistic regression analysis was employed to identify risk factors for myopia, and analyze the relationship between eye-use behaviors and myopia development or progression.RESULTS:A total of 2 986 children complete a follow-up for 2 a. The baseline prevalence of poor vision was 32.74%, increasing to 38.92% and 43.73% at 1 and 2 a follow-up, respectively, demonstrating a yearly upward trend. Taking uncorrected visual acuity combined with non-cycloplegic refraction as clinical screening criteria for myopia, the incidence was 24.72%, 27.60%, and 29.64% at baseline, 1, and 2 a follow-ups, respectively. These showed no statistical significant difference compared to the diagnostic standard of cycloplegic refraction SE(23.98%, 27.03%, and 29.17%; all P>0.05). Logistic regression analysis found that daily outdoor and sleep duration were protective factors against myopia(OR=0.54, 0.84, all P<0.05), while age, parental myopia, duration of offline education, online education, electronic device usage, and poor visual posture were identified as risk factors(OR=2.72, 1.54, 1.72, 1.12, 1.47, 1.26, all P<0.001). Further analysis of myopia progression in baseline myopic children over 2 a revealed that age, parental myopia, baseline SE, duration of offline/online education, electronic device usage, and poor visual posture may contribute to rapid myopia progression.CONCLUSION:Under the background of “double reduction”, the eye-use behavior among primary school students in Minhang District, Shanghai has an important impact on the occurrence and development of myopia. In order to effectively prevent and control myopia, it is necessary to further strengthen the education and guidance of eye-use behavior.

Osteoporosis is a prevalent skeletal condition characterized by reduced bone mass and strength, leading to increased fragility. Buqi-Tongluo (BQTL) decoction, a traditional Chinese medicine (TCM) prescription, has yet to be fully evaluated for its potential in treating bone diseases such as osteoporosis. To investigate the mechanism by which BQTL decoction inhibits osteoclast differentiation in vitro and validate these findings through in vivo experiments. We employed MTS assays to assess the potential proliferative or toxic effects of BQTL on bone marrow macrophages (BMMs) at various concentrations. TRAcP experiments were conducted to examine BQTL's impact on osteoclast differentiation. RT-PCR and Western blot analyses were utilized to evaluate the relative expression levels of osteoclast-specific genes and proteins under BQTL stimulation. Finally, in vivo experiments were performed using an osteoporosis model to further validate the in vitro findings. This study revealed that BQTL suppressed receptor activator of NF-κB ligand (RANKL)-induced osteoclastogenesis and osteoclast resorption activity in vitro in a dose-dependent manner without observable cytotoxicity. The inhibitory effects of BQTL on osteoclast formation and function were attributed to the downregulation of NFATc1 and c-fos activity, primarily through attenuation of the MAPK, NF-κB, and Calcineurin signaling pathways. BQTL's inhibitory capacity was further examined in vivo using an ovariectomized (OVX) rat model, demonstrating a strong protective effect against bone loss. BQTL may serve as an effective therapeutic TCM for the treatment of postmenopausal osteoporosis and the alleviation of bone loss induced by estrogen deficiency and related conditions.

ObjectiveTo investigate the prevalence and associated factors of malocclusion among preschool children in Fengxian District, Shanghai, and to provide a scientific basis for local medical and public health departments to formulate targeted interventions. MethodsA cross-sectional study was conducted from September to December 2024. A total of 1 172 children aged 3‒5 years were recruited from 10 kindergartens across 5 townships in Fengxian District, using stratified cluster random sampling method. Clinical examinations were conducted to record occlusal parameters such as the relationship of the second deciduous molars, canine teeth relationship, anterior overbite and overjet, anterior and posterior crossbite, and crowded dentition. A questionnaire survey was performed to the parents to collect information on factors influencing malocclusion, including genetic predisposition, poor oral habits, dietary patterns, and sleep-related breathing conditions. Data were statistically analyzed using IBM SPSS Statistics 27 software, with chi-square test for categorical data and binary logistic regression analysis for influencing factors. ResultsThe overall prevalence of malocclusion among 3‒5-year-old children in Fengxian District of Shanghai was 70.73%, with no statistically significant differences between genders (P>0.05). Deep overbite accounted for the highest proportion (49.66%), followed by Angle Class Ⅱ malocclusion of the second deciduous molars (17.83% on the left, 19.11% on the right), midline deviation (13.23%), anterior crossbite (6.74%), and crowding of the maxillary and mandibular anterior teeth (16.38% for the maxillary dentition, 17.58% for the mandibular dentition). Multivariate analyses showed that habitual mouth breathing during the day (OR=0.509, P=0.009) and morning dry mouth upon waking (OR=1.455, P=0.023) were independent influencing factors for malocclusion. ConclusionThe prevalence of malocclusion is relatively high among preschool children in Fengxian District, Shanghai,with deep overbite being the dominant trait. Sleep-related breathing conditions (such as habitual mouth breathing during the day and morning dry mouth) is an important influencing factor for malocclusion. Public health authorities should strengthen oral health education and promote the correction of bad habits to reduce the prevalence of malocclusion and improve children’s oral health.

As the most abundant and essential structural protein in the human body, collagen is ubiquitously present in the interstitium of nearly all solid organs, playing a crucial role in maintaining the structural integrity and functional stability of human tissues and organs. Disorders associated with collagen structure and metabolisms impose a significant burden on society and healthcare systems. Post-translational modifications (PTMs) are essential steps in collagen metabolism, and recent studies have indicated that aberrant regulation of PTMs plays a pivotal role in the pathogenesis and progress of collagen-related disorders, including liver, kidney, heart, lung, and skin fibrosis, as well as keloid. This review provides a comprehensive summary of the regulatory mechanisms of both traditional and novel PTMs in collagen metabolism and collagen-related diseases. Furthermore, we summarize the drugs that modulate PTMs and their effects, with the aim of elucidating the pathophysiology of collagen-related diseases and provide new insights for their diagnosis, prevention, and treatment.

Colorectal tumorigenesis generally progresses from adenoma to adenocarcinoma, accompanied by dynamic changes in the tumor microenvironment (TME). A randomized controlled trial has confirmed the efficacy and safety of Shen-Bai-Jie-Du decoction (SBJDD) in preventing colorectal tumorigenesis. However, the mechanism remains unclear. In this study, we employed single-cell RNA sequencing (scRNA-seq) to investigate the dynamic evolution of the TME and validated cell infiltration with multiplex immunohistochemistry and flow cytometry. Bulk RNA sequencing was utilized to assess the underlying mechanisms. Our results constructed the mutually verifiable single-cell transcriptomic atlases in Apc ^Min/+ mice and clinical patients. There was a marked accumulation of CCL22⁺ dendritic cells (DCs) and an enhanced immunosuppressive action, which SBJDD and berberine reversed. Combined treatment with cholesterol and lipopolysaccharide induced characteristic gene expression of CCL22⁺ DCs, which may represent "exhausted DCs". Intraperitoneal injection of these DCs after SBJDD treatment eliminated its therapeutic effects. TMEM131 derived CCL22⁺ DCs generation by TNF signaling pathway and may be a potential target of berberine in retarding colorectal tumorigenesis. These findings emphasize the role of exhausted DCs and the regulatory mechanisms of SBJDD and berberine in colorectal cancer (CRC), suggesting that the multi-component properties of SBJDD may help restore TME homeostasis and offer novel cancer therapy.
