Objective To compare the clinical efficacy between liposuction combined with circumareolar small incision and three-port endoscopic surgery for the treatment of Simon Ⅱ gynecomastia (GYN). Methods Comparative case data of 120 patients with GYN were retrospectively analyzed, 61 patients in the open group underwent circumareolar small incision mastectomy after liposuction, and 59 patients in the endoscopic group underwent three-port endoscopic mastectomy after liposuction. The two groups were compared in terms of surgery-related indexes, occurrence of postoperative complications and patient satisfaction. Results The unilateral operation time of the open group was shorter than that of the endoscopic group, the unilateral gland resection weight in the open group was more than that in the endoscopic group, the hospitalization cost of the open group was less than that of the endoscopic group (all P<0.01). There was no significant difference in unilateral liposuction volume, drainage volume on the first postoperative day, and time to drain removal between the two groups (P>0.05). The incidence of complications in the open group and the endoscopic group were 8.2% and 13.6% respectively, and there was no significant difference between the two groups (P>0.05). The difference in the overall satisfaction scores between the two groups was not statistically significant (P>0.05). Conclusions Liposuction combined with circumareolar small incision or three-port endoscopic surgery both has good cosmetic effects in the treatment of Simon Ⅱ GYN. The operation with circumareolar small incision is simple, has a shorter operation time, costs less, and does not require special equipment, which is suitable for promotion and application in medical institutions.

Reactive astrocytes, which exhibit a correlation with the degeneration of dopaminergic neurons, are present in a considerable number during the progression of Parkinson's disease (PD). However, the underlying factors shaping astrocyte reactivity and neuroinflammation in PD remain inadequately elucidated. Here, we demonstrate that fibroblast growth factor 7 (FGF7)/FGF receptor 2 (FGFR2) autocrine signaling intensifies astrocyte reactivity and inflammation. Genetic deletion of Arrb2, β-Arrestin2 encoding gene, led to escalated astrocyte reactivity in MPTP-treated mice, which was further substantiated in astrocyte-specific Arrb2 knockdown mice. RNA sequencing profiling of Arrb2 knockout astrocytes identified Fgf7 as a critical effector of astrocyte reactivity. Subsequently, conditional knockdown of Fgf7 and its receptor Fgfr2 in astrocytes elicited advantageous effects for MPTP-treated mice by restraining the inflammatory phenotypic transition of reactive astrocytes. Furthermore, deletion of astrocytic Fgf7 mitigated MPTP-induced pathology in Arrb2 knockout mice. Mechanistically, STAT1 was distinguished as the transcription factor suppressing Fgf7 expression, while β-Arrestin2 counteracted the proteasomal degradation of STAT1 by binding to RNF220, an E3 ubiquitin ligase for STAT1. More importantly, selectively engaging dopamine D2 receptor (Drd2)/β-Arrestin2-biased signaling using the agonist UNC9995 exhibited therapeutic potential in MPTP-treated mice via moderation of astrocytic FGF7 production, thereby restoring balance in astrocyte reactivity. Collectively, our study bridges a crucial knowledge gap by elucidating the novel functions of FGF family members within the central nervous system, particularly within the context of PD. The autocrine signaling of FGF7/FGFR2 represents a novel mechanism and a potential druggable target for modulating astrocyte-derived inflammation.

Objective:To analyze the clinical characteristics of adult patients with phytosterolemia presenting with thrombocytopenia as the initial manifestation.Methods:A retrospective analysis was conducted on eight adult patients with phytosterolemia who visited Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from December 2020 to December 2023.Results:① The participants consisted of 2 (25%) male and 6 (75%) female patients, with a median age at diagnosis of 55 years (range: 29-66 years). The median duration from the discovery of thrombocytopenia to diagnosis was 10 years (range: 0.2-50 years). ② Compared with the normal control group (30 healthy adult volunteers) and the immune thrombocytopenia (ITP) control group (20 patients with ITP), patients with phytosterolemia exhibited significantly higher mean platelet volume and large platelet ratio. Peripheral blood smears revealed that the mean platelet diameter and the proportion of large platelets (diameter> 4 μm) were significantly higher in patients with phytosterolemia than those in the normal and ITP control groups ( P<0.01). ③ After a low-plant-sterol diet and ezetimibe treatment, five patients demonstrated decreased serum sitosterol and campesterol levels, increased hemoglobin concentration and platelet counts, and reduced platelet volume. Conclusion:Adult-onset phytosterolemia presenting with thrombocytopenia as the initial manifestation is prone to misdiagnosis. The presence of hemolytic anemia, splenomegaly, increased large platelets and schistocytes on peripheral blood smears, and xanthomas are crucial diagnostic indicators. Restricting dietary plant sterol intake and using ezetimibe to inhibit sterol absorption effectively lowers serum plant sterol levels and improves hematological abnormalities.

Objective:To conduct a scoping review of financial toxicity assessment tools both domestically and internationally,and to summarize their scoring methods,evaluation content,development approaches,reliability/validity,and application status,aiming to provide references for selecting or developing such tools.Methods:Following scoping review methodology,databases including CNKI,VIP,Wanfang,PubMed,Web of Science,Embase,and CINAHL were searched for studies on financial toxicity assessment tools,with the search period spanning from database inception to Oct 8,2024.Results:A total of 34 eligible studies were included,covering 14 financial toxicity assessment tools.These tools primarily focused on economic status,psychosocial responses,or coping behaviors.Tools developed by domestic scholars exhibited strong specificity but lacked generalizability.Conclusions:Existing financial toxicity assessment tools are diverse,yet their reliability and validity in Chinese patient populations require further validation.Most scales lack comprehensive dimensions,and domestically developed tools are overly specific.A universal assessment tool suitable for China's cultural and policy environment needs to be developed.

Objective:To analyze the evaluation of the “1+1+2M” healthcare management model (outpatient core medical staff+ward core medical staff+multi interdisciplinary team+multi department coordination) by healthcare workers in a large public hospital and its influencing factors.Methods:It was a cross-sectional study, using the judgment sampling method to select 70 healthcare workers in the hospital healthcare department in November 2024. A self-designed public hospital healthcare management model evaluation questionnaire was used to investigate the “1+1+2M” healthcare management model. A total of 70 questionnaires were distributed, and 70 valid questionnaires were collected (100%). The basic information, team integration, human resource allocation, and evaluation of healthcare management models in the healthcare workers were collected. The factors affecting healthcare worker evaluation were identified with Kruskal Wallis test and multiple logistic regression analysis.Results:Among the 70 healthcare workers included in the analysis, there were 30 doctors, 30 nursing staff, and 10 management/technical personnel; 19 males and 51 females; more than 70% of the participants were aged 50 years or younger; the length of service was (19.11±9.44) years, and the length of service for healthcare was (9.79±6.06) years. Healthcare workers showed high satisfaction with the “1+1+2M” healthcare management model, with an overall satisfaction rate of 87.14% (61/70). The evaluation of work collaboration, business norms, and mode configuration by healthcare workers was positively correlated with the evaluation of healthcare management mode [very satisfied with health management mode: relatively satisfied with work collaboration ( OR=0.064, 95% CI: 0.004-0.965), satisfied with business norms ( OR=0.018, 95% CI: 0.001-0.312), relatively satisfied with business norms ( OR=0.061, 95% CI: 0.004-0.938), satisfied with mode configuration ( OR=0.006, 95% CI: 0.000-0.111); satisfied with health management mode: satisfied with business norms ( OR=0.049, 95% CI: 0.005-0.498), satisfied with mode configuration ( OR=0.074, 95% CI: 0.006-0.943)] (all P<0.05). Conclusions:The health care staff in a large public hospital have a good evaluation of the operation effect of the “1+1+2M”health management model. The higher the evaluation of work collaboration, business norms, and model configuration by the health care staff, the higher the overall satisfaction with the health management model.
