BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

OBJECTIVE: To evaluate the early effectiveness of transosseous suture fixation in treating recurrent acute patellar dislocation with patellar osteochondral fractures (OCFs). METHODS: A retrospective analysis was conducted on 19 patients with recurrent acute patellar dislocation and patellar OCFs, who underwent transosseous suture fixation between January 2018 and December 2022 and were followed up 2 years. The cohort included 8 males and 11 females, aged 13-21 years (mean, 16.2 years). Patients experienced 2-5 times of patellar dislocation (mean, 3.2 times). The interval from the last dislocation to operation ranged from 3 to 15 days (mean, 9.6 days). Preoperative imaging revealed the intra-articular osteochondral fragments and medial patellofemoral ligament (MPFL) injury. Clinical outcomes were evaluated using the visual analogue scale (VAS) score for pain, the International Knee Documentation Committee (IKDC) score, the Hospital for Special Surgery (HSS) knee score, the Lysholm score, and the Tegner score. Postoperative complications were recorded. During follow-up, the knee X-ray films, CT, and MRI were taken to evaluate fragment healing, displacement, and the morphology and tension of the MPFL reconstruction graft. RESULTS: All incisions healed primarily, and no complication occurred such as infection, joint stiffness, patellofemoral arthritis, or redislocation. Patients were followed up 24-60 months (mean, 43.5 months). At 12 months postoperatively and the last follow-up, significant improvements ( P<0.05) were observed in VAS, Lysholm, IKDC, HSS, and Tegner scores compared to preoperative values. Further improvements were observed at last follow-up compared with the 12 months postoperatively, and the differences were significant ( P<0.05). Imaging studies demonstrated satisfactory osteochondral fragment positioning with stable fixation. At last follow-up, all fragments had healed, and MPFL reconstruction grafts exhibited optimal morphology and tension. No joint adhesion or fragment displacement occurred. CONCLUSION For recurrent acute patellar dislocation with patellar OCFs, transosseous suture fixation proves to be both safe and effective, achieving satisfactory early effectiveness.

Objective To investigate the role of JAK2/STAT3 signaling pathway mediated Treg/Th17 imbalance in children with cow's milk protein allergy and the effect of dietary avoidance on the imbalance.Methods A total of 103 children with cow's milk protein allergy in the hospital were enrolled and divided in-to the IgE-mediated group(n=38)and the non-IgE-mediated group(n=65).All patients underwent a 3-month strict dietary avoidance intervention.A total of 100 healthy children who underwent health checkups at the hospital's physical examination center during the same period,with no history of food allergy or other im-mune-related diseases,were selected as the healthy control group.The percentages of Treg and Th17 cells were measured by flow cytometry.The mRNA expression levels of JAK2,STAT3,SOCS1,and SOCS3 were determined by qPCR.Differences between groups,changes before and after dietary avoidance,and correlations between these indicators and clinical symptoms were analyzed using Pearson's test.Results At baseline,both the IgE-mediated group and the non-IgE-mediated group had significantly lower Treg percentages and SOCS1/SOCS3 mRNA levels,and higher Th17 percentages and JAK2/STAT3 mRNA levels compared to the healthy control group(P＜0.05).After dietary avoidance,Treg percentages and SOCS1/SOCS3 mRNA levels in-creased,while Th17 percentages and JAK2/STAT3 mRNA levels decreased in the IgE-mediated group and the non-IgE-mediated group(P＜0.05).The increase of Treg percentage and the decrease of Th17 percentage in the non-IgE-mediated group were greater than in the IgE-mediated group,whereas the increases of SOCS1 and SOCS3 mRNA levels were smaller in the non-IgE-mediated group(P＜0.05).Logistic regression identified JAK2,STAT3,SOCS1,and SOCS3 mRNA levels as factors influencing Treg and Th17 percentages(P＜0.05).Pearson correlation analysis revealed that allergic symptom scores and serum milk-specific IgE levels were positively correlated with JAK2/STAT3 mRNA levels and Th17 percentage,and negatively correlated with SOCS1/SOCS3 mRNA levels,Treg percentage,and the Treg/Th17 ratio(P＜0.05).Conclusion Dieta-ry avoidance can modulate the activity of JAK2/STAT3 signaling pathway,with a more pronounced improve-ment in non-IgE-mediated cow's milk protein allergy.

Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.

Objective:To investigate mevalonic acid(MEV)on reversing the antitumor effects of fluvastatin sodium(FS)on tongue squamous cell carcinoma(TSCC)cells.Methods:TSCC HSC-4 cells were treated with different concentrations of FS and MEV re-spectively or in combination.Cell counting kit-8,flow cytometry,wound healing,immunofluorescence and western blotting assays were conducted to examine cell proliferation,apoptosis and migration capacities,as well as the expression levels of Ras homolog family member A(RHOA),tissue factor(TF)and B-cell lymphoma-2-associated X(BAX)proteins,respectively.Results:FS inhibited HSC-4 cell proliferation and migration,decreased the expression of RHOA and TF,and increased BAX expression.MEV reversed the above antitumor effects of FS and promoted intracellular RHOA and TF expression.Conclusion:MEV reverses the antitumor effects of FS on HSC-4 cells in vitro.

ABSTRACT OBJECTIVE To explore the correlation between HPLC fingerprint and analgesic efficacy of Zhejiang vinegar Corydalis Rhizoma, and to screen out the material basis of analgesic effect of Zhejiang vinegar Corydalis Rhizoma.METHODS Established HPLC fingerprint of Zhejiang vinegar Corydalis Rhizoma and dysmenorrhea model in rats. The weight loss rate, writhing response, serum malondialdehyde(MDA), estradiol(E2), prostaglandin E2(PGE2) and prostaglandin F2α(PGF2α) levels were used as the evaluation indexes of analgesic efficacy. Combined with chemometrics, the main active components of analgesic effect of Zhejiang vinegar Corydalis Rhizoma and the important components with great contribution to the content were screened.RESULTS The fingerprints of different batches of Zhejiang vinegar Corydalis Rhizoma were established, and nine components were identified; compared with the blank group, the weight loss rate, writhing reaction, MDA, E2 and PGF2α levels in the model group were significantly increased. Compared with the model group, the above indexs in the administration group was decreased. Compared with the blank group, the PGE2 level in the model group was significantly decreased. Compared with the model group, the PGE2 level in the administration group was significantly increased. The vinegar Corydalis Rhizoma produced in Zhejiang had a good analgesic effect, and the main active components of its analgesic effect were protopine, palmatine hydrochloride, and dehydrocorydaline. The important components with greater contribution to the content were tetrahydropalmatine, protopine, palmatine hydrochloride and stylopine.CONCLUSION The efficacy of Zhejiang vinegar Corydalis Rhizoma is the result of the combined action of multiple components, and each component has a strong correlation with the pharmacodynamic indexes. This study provides a reference for the screening of analgesic material basis of Zhejiang vinegar Corydalis Rhizoma.

Objective To culture and expand primary rat aortic vascular stem cells in vitro and evaluate their characteristics as mesenchymal stem cells.Methods The thoracic and abdominal aortas isolated from 2-to 3-week-old Sprague-Dawley rats were cut into vascular segments 2.0 mm in length and cultured in culture flasks till adhesion and solidification of the outer membranes.The primary cells were further cultured to 80%-90%confluence before passaging.The morphology and growth characteristics of the cells were observed under a microscope,and the expressions of surface marker CD molecules on the cells was analyzed using flow cytometry.Adipogenic and osteogenic differentiation assays were performed to assess the capacity of the cells for multilineage differentiation.Results After 3 days of culture,a small number of spindle,star-shaped or polygonal cells migrated out from the peripheral of the vascular segments.At 5-6 days,island-like cell clusters occurred and the cells began to proliferate rapidly.The cell clusters expanded radially and showed signs of cell cloning.At 7-8 days,the cells fused into sheets and displayed a vortex-like distribution.The cells in the third passage presented with a uniform morphology,showing a typical fibroblast-like arrangement.Flow cytometry showed that the cells expressed predominantly CD44(80.3%),CD73(62.2%)and CD90(46.8%)with low expressions of CD34(1.1%),CD45(0.2%)and CD11b/c(0.2%).Adipogenic and osteogenic differentiation experiments demonstrated that the cells were capable of lipogenic and osteogenic differentiation in vitro.Conclusion Rat aortic vascular stem cells with mesenchymal stem cell characteristics can be successfully isolated and cultured by adherent culture of the segmented outer membrane.
