Objective:To investigate the clinical characteristics, bleeding site distribution, and factors associated with hospitalization for surgical management in patients with refractory posterior epistaxis.Methods:This cross-sectional study retrospectively analyzed data from 3 473 patients with refractory posterior epistaxis treated at ENT department or Emergency Department of Affiliated Zhangzhou Hospital of Fujian Medical University, between January 2018 and December 2024. The demographic and clinical data of patients were collected. Univariate analyses and multivariable logistic regression were applied to identify factors associated with hospitalization for surgical intervention.Results:Among 3 473 patients (65.94%(2 290 cases) male; mean age (54±21) years), 46.96% (1 631 cases)were aged 41-69 years. Bleeding predominantly occurred at night (89.66%, 3 114 cases) and in winter (29.92%, 1 039 cases). The most frequent bleeding sites were the olfactory cleft (25.22%,876 cases) and inferior meatus vault (25.63%,890 cases), followed by the posterior regions of middle meatus (11.26%,391 cases), the foremost regions of nasal cavity (11.20%,389 cases), the nasal septum surface (11.23%,390 cases), the bottom of nasal cavity (9.42%,327 cases), and the others or uncertain sites (6.05%,210 cases). Endoscopic electrocautery was performed in 75.01% of cases. Overall, 2 715 patients required hospitalization for surgery. Univariate analysis identified older age (≥70 years), male sex, alcohol use, nighttime onset, winter season, hypertension, diabetes, and anticoagulant use as significantly associated with hospitalization ( χ2=6.51, 8.03, 5.11, -0.17, 7.53, 12.52, 6.83, 5.18, all P<0.05). Multivariable logistic regression confirmed older age ( OR=2.45, 95% CI: 1.81-7.50), winter season ( OR=9.55, 95% CI: 2.26-9.38), nighttime onset ( OR=6.78, 95% CI: 1.84-6.96), alcohol use ( OR=27.71, 95% CI: 11.97-64.14), hypertension ( OR=7.93, 95% CI: 1.64-11.84), and anticoagulant use ( OR=6.39, 95% CI: 1.06-9.47) as independent positive factors associated with hospitalization for surgical management (all P<0.05). Conclusions:Refractory posterior epistaxis most commonly affects individuals aged 41-69 years, with bleeding frequently originating from the olfactory cleft or inferior meatus vault, and exhibits seasonal (winter) and diurnal (nighttime) patterns. Independent factors significantly associated with the need for hospitalization and surgical intervention include older age, winter onset, nighttime onset, alcohol use, hypertension, and anticoagulant use. Identifying these factors may aid in risk stratification and clinical decision-making.

Precise management of the activity dose is a core component of the(early mobilization,EM)plan for ICU patients.However,the lack of clinical practice guidelines related to EM dose of existing programs hinders the implementation and development of EM in ICU patients to some extent.Therefore,this review focuses on 4 aspects,covering the definition of activity dose,assessment tools,the current clinical implementation status,and implications for future nursing.The aim is to systematically review the assessment tools and intervention strategies for the activity dose of EM in ICU patients,providing a reference for optimization of EM programs.

Objective:To investigate the epileptogenic networks of bilateral asymmetric tonic seizures (BATS) originating from the posterior insula using stereo-electroencephalography (SEEG).Methods:A retrospective analysis was performed. Among the epilepsy patients who underwent preoperative assessment and SEEG monitoring in the Epilepsy Department of Guangdong Sanjiu Brain Hospital from January 1, 2015 to July 1, 2024, 7 patients with insular epilepsy characterized by BATS originating from the posterior insula were selected based on anatomo-electro-clinical characteristics. The clinical characteristics, neuroimaging features, scalp EEG patterns, and SEEG recordings of the 7 patients were collected and analyzed. Via synchronously analyzing ictal semiology and electroanatomical propagation pathways shown by SEEG, the features of epileptogenic networks were elucidated. Results:Four patients had seizure onset from the dorsal-superior part of the left posterior insula, and 3 patients from the dorsal-superior part of the right posterior insula. The electroencephalographic characteristics of the seizure onset zones showed high consistency in these 7 patients: rhythmic spike or multiple spike discharges at the initial stage, and a low-amplitude rapid rhythm pattern subsequently. Totally, 3-10 seizures were recorded in each patient. Four patients experienced prodromal symptoms, including 3 patients with somatosensory symptoms (1 with chest and abdominal pain, 1 with contralateral facial numbness combined with throat constriction sensation, and 1 with contralateral limb numbness), and 1 patient with non-specific presentation (hugging family member before seizure). The seizure semiological evolution sequence was from prodrome to BATS, and then to secondary symptoms, with 3 patients exhibiting clustered spasms as secondary symptoms, and 4 patients showing eyelids and contralateral upper limb distal tonic-clonic manifestations as secondary symptoms. The epileptogenic networks followed a consistent pattern: the dorsal-superior part of the posterior insula leads to the middle-posterior part of the superior circular sulcus, to the ventral posterior insular and posterior circular sulcus, and then to the supplementary sensorimotor area (SSMA), and finally to the central sulcus, central region-vertex, and inferior parietal lobule. Only 2 patients had the anterior insular-involved epileptic brain networks, while the remaining 5 patients did not involve the anterior insular. During BATS, SEEG electrode contacts corresponding to the posterior insular, superior circular sulcus and SSMA exhibited low-amplitude rapid rhythm patterns.Conclusion:The seizures spread from the dorsal-superior part of the posterior insula to the middle-posterior part of the superior circular sulcus at the early stage of onset, and then connected with SSMA; these structures formed a epileptogenic brain network through abnormal synchronous discharge, which eventually led to BATS.

Objective Cheng's Juanbi Decoction(CSJBD)is a classic traditional Chinese medicine formula for treating rheumatoid arthritis(RA),exhibiting significant clinical efficacy,but the underlying mechanisms remain unclear.We investigated whether CSJBD inhibited RA pathology by blocking the WTAP-Wnt7b-Wnt/β-catenin signaling axis using a collagen-induced arthritis(CIA)mouse model and fibroblast-like synoviocytes(FLSs)derived from RA patients(RA FLSs)and examined the underlying mechanisms.Methods We conducted in vivo experiments.Male C57BL/6 mice weighing 17 to 20 g were used to establish the CIA model.The mice were assigned to 6 groups,including the normal group,the model(CIA)group,the model+CSJBD-L(8.1 g/kg)group,the model+CSJBD-M(16.2 g/kg)group,the model+CSJBD-H(32.4 g/kg)group,and the model+leflunomide(LEF)(0.05 mg/10 g)group,with 10 mice in each group.CSJBD was administered twice daily via gastric gavage,while LEF was administered once daily via gastric gavage,for a duration of 28 days.We also conducted in vitro experiments.RA FLSs were assigned to 4 groups,including the RA FLSs+CSJBDS-L group receiving 10%CSJBDS-containing serum,the RA FLSs+CSJBDS-M group receiving 15%CSJBDS-containing serum,the RA FLSs+CSJBDS-H group receiving 20%CSJBDS-containing serum,and the RA FLSs+NC group(negative control).To study whether WTAP regulated Wnt7b,RA FLSs were divided into the RA FLSs group,the RA FLSs+si-WTAP#3 group,the RA FLSs+si-WTAP#3+Wnt7b-OE group,and the RA FLSs+si-WTAP#3+Wnt7b-NC group.To study the underlying mechanism by which CSJBT affected RA FLSs,RA FLSs were divided into the RA FLSs group,the RA FLSs+CSJBDS-M group,the RA FLSs+CSJBDS-M+Wnt7b-OE group,and the RA FLSs+CSJBDS-M+NC group.We used ultra-high performance liquid chromatography(UPLC)to identify and quantify key monomer compounds from CSJBD as quality criteria for CSJBD preparation.Bioinformatics,CCK-8,RT-qPCR,Western blot,immunofluorescence,and related methods were employed to assess the therapeutic efficacy and underlying mechanisms of CSJBD in treating RA.Results According to the UPLC analysis,ferulic acid,osthole,mulberroside A,notopterol,and gentiopicroside were identified as quality control standards for the preparation of CSJBD formula.CSJBD improved RA pathology in CIA mice,reduced the levels of interleukin(IL)-6,IL-1β,IL-8,and tumor necrosis factor-α(TNF-α)in their serum,and decreased the expression of RA pathological genes MMP3 and fibronectin,with the difference between groups being statistically significant.Bioinformatics analysis suggested that CSJBD might inhibit RA pathology by suppressing the Wnt/β-catenin signaling pathway through Wnt7b.Experimental results showed that the expression of WTAP and Wnt7b was significantly increased in RA.After knocking down WTAP,the expression of Wnt7b was significantly reduced,and the Wnt/β-catenin signaling pathway was also inhibited,with the difference between groups being statistically significant(P<0.05),confirming that WTAP regulated the pathway via Wnt7b.According to experimental verification,CSJBD significantly inhibited the Wnt/β-catenin signaling pathway and the proliferation of RA FLSs.Wnt7b overexpression reversed the inhibitory effect of CSJBD on the Wnt/β-catenin signaling pathway and the proliferation of RA FLSs,indicating that Wnt7b is the direct target of CSJBD.Conclusion CSJBD inhibits RA pathology by blocking the WTAP-Wnt7b-Wnt/β-catenin signaling axis,with Wnt7b identified as a direct therapeutic target of CSJBD.

Objective To retrospectively assess the clinical efficacy of acupuncture at the Huiyin point combined with Qingdu wash solution in the treatment of high-risk HPV infection.Methods A total of 264 patients who were initially diagnosed with high-risk HPV infection at the University City Gynecology Department of Guang-dong Provincial Hospital of Traditional Chinese Medicine between January 2022 and June 2024 were enrolled in the study.These patients were divided into two groups based on predefined inclusion and exclusion criteria.The ob-servation group included 134 patients who received acupuncture at the Huiyin acupoint combined with Qingdu wash solution,while the control group consisted of 130 patients who did not receive any intervention.The treatment pe-riod lasted for three months,during which the short-term clinical efficacy and safety profile were evaluated.Results The HR-HPV clearance rates in the observation group at 3 months and 6 months were 61.9%and 65.7%,respectively,which were significantly higher than those in the control group(16.9%and 21.5%),and the differences between the two groups were statistically significant(P<0.001).Following a three-month treatment regimen,the rate of HR-HPV positive-to-negative conversion in the observation group was significantly higher than that in the control group,with a statistically significant intergroup difference(P<0.001).The improvement in tra-ditional Chinese medicine(TCM)-related symptoms was also significantly better in the observation group compared to the control group(P<0.05).During the follow-up period,no cases of recurrence were observed in the observa-tion group,whereas the recurrence rate in the control group was 1.5%.Furthermore,no adverse reactions were re-ported in the observation group throughout the treatment period.Conclusion Acupuncture at the Huiyin point,when combined with Qingdu wash solution,can enhance the therapeutic outcomes of high-risk HPV infection and demonstrates a favorable safety profile.

Objective:To explore whether LBP3 exerts anti-tumor effects by promoting production of short-chain fatty acids(SCFAs)by intestinal microbiota and regulating function of polymorphonuclear myeloid-derived suppressor cells(PMN-MDSC).Methods:A subcutaneous H22 liver cancer model was employed to assess anti-tumor activity of LBP3 and its regulatory effects on PMN-MDSC.Pseudo-sterile tumor-bearing mouse model was used to investigate role of intestinal microbiota in tumor suppression of LBP3.Fecal microbiota transplantation(FMT)was conducted to explore immune regulatory role of LBP3-modulated flora.Serum SCFAs levels in tumor-bearing mice were quantified using liquid chromatography-mass spectrometry,and effect of SCFAs butyrate on arginase 1(Arg-1)expression was evaluated in vitro.Results:Both low-dose(125 mg/kg)and high-dose(250 mg/kg)LBP3 signifi-cantly inhibited tumor growth in H22 tumor-bearing mice,also led to a marked reduction in proportion of PMN-MDSC in both spleen and tumor,a reduced proportion of Treg in lymphoid tissues,a decrease in Arg-1 level within tumor,infiltration of CD8+T cells into tumor was significantly enhanced.However,these effects of LBP3 were did not observed in pseudo-sterile mice,while the above changes could be reproduced after fecal supernatant transplantation in high-dose LBP3 treatment group,suggesting a crucial role for gut microbiota.Furthermore,co-expression of Ly6G and SCFA receptor GPR43 in tumor was also observed.LBP3 treatment resulted in increased levels of SCFAs,particularly butyrate,in both blood and tumor tissues.In vitro,butyrate was shown to inhibit Arg-1 expression in MSC-2 cells,further supporting hypothesis that SCFAs mediate immune-modulatory effects of LBP3.Conclusion:LBP3 exerts its anti-tumor effects by promoting SCFA production,which subsequently inhibits function of PMN-MDSC.This highlights LBP3's potential as an immunomodulatory agent in cancer therapy.
