Objective:This study aimed to analyze the prognostic risk factors for hepatoid adenocarcinoma of the stomach (HAS) and construct two nomogram-based clinical prediction models to predict overall survival (OS) and recurrence-free survival (RFS) in patients with HAS.Methods:Data were retrospectively collected from 82 patients (64 males, 18 females; mean age 60.3 ± 9.4 years) who underwent radical gastrectomy and were pathologically diagnosed with gastric hepatoid adenocarcinoma at the First Medical Center of the PLA General Hospital between February 2006 and September 2023. Statistical analyses were conducted using SPSS 25.0 and R 4.3.2. Survival analyses were performed using the Kaplan-Meier method, and univariate analyses were used to identify clinical and pathological factors associated with prognosis. Variables with P<0.05 in the univariate analysis were included in multivariate Cox regression models to identify independent risk factors for OS and RFS. These factors were incorporated into the prediction models to construct nomograms. The discriminatory power of the models was assessed using the area under the curve (AUC) of receiver operating characteristic (ROC) analyses, while calibration curves, decision curve analysis (DCA), and comparisons with the 8th edition of the TNM staging system of the American Joint Committee on Cancer (AJCC) were employed to evaluate model performance. Results:Among the 82 patients, 36 (43.9%) exhibited vascular infiltration, 61 (74.4%) had nerve infiltration, and lymph node metastasis was observed in 60 cases (73.2%). Pathological stages I, II, III, and IV were distributed as 11 (13.4%), 26 (31.7%), 44 (53.7%), and 1 (1.2%) cases, respectively. Inflammatory markers included neutrophil-to-lymphocyte ratio (NLR) ≥ 4.33 in 22 cases (26.8%), platelet-to-lymphocyte ratio (PLR) ≥ 142.2 in 50 cases (61.0%), monocyte-to-lymphocyte ratio (MLR) ≥ 0.411 in 22 cases (26.8%), α-fetoprotein (AFP) ≥ 2.48 μg/L in 64 cases (78.0%), and C-reactive protein (CRP) ≥ 7.506 mg/L in 12 cases (14.6%). Among the 82 patients, 3 cases (3.6%) were lost to follow-up. The median follow-up time was 52 (range: 8–147) months, with a median OS of 61(2–147) months. The 1-year and 3-year OS rates were 78.5% and 58.5%, respectively, while the 1-year and 3-year RFS rates were 77.3% and 60.3%, respectively. Multivariate analysis identified several independent risk factors influencing OS in patients with HAS: advanced pathological stage, MLR ≥ 0.411, AFP ≥ 2.545 μg/L, and CRP ≥ 7.51 mg/L. The hazard ratios (HRs) and 95% confidence intervals (CIs) were as follows: 5.218 (1.230–22.143), 2.610 (1.287–5.294), 2.950 (1.013–8.589), and 2.594 (1.145–5.877), respectively (all P < 0.05). For RFS, advanced pathological stage, PLR ≥ 152.0, and MLR ≥ 0.411 were independent risk factors, with HRs (95% CIs) of 4.735 (1.080–20.760), 3.759 (1.259–11.226), and 2.714 (1.218–6.048), respectively (all P < 0.05). The AUC values for OS prediction at 1 year, 3 years, and 5 years were 0.7765, 0.7525, and 0.7702, respectively. For RFS, the AUC values were 0.7304, 0.8137, and 0.8307 at 1 year, 3 years, and 5 years, respectively. The calibration curves demonstrated strong agreement between nomogram- predicted outcomes and observed survival data. DCA indicated that both TNM staging and the nomogram-based clinical prediction models provided a net positive benefit in predicting OS and RFS in HAS patients, with the nomogram model demonstrating superior performance. Conclusion:The nomogram-based clinical prediction models developed in this study demonstrated robust performance in predicting long-term OS and RFS in patients with HAS.

Objective:To investigate the feasibility and safety of endovascular mechanical thrombectomy (EMT) combined with continuous intrasinus thrombolysis for the treatment of severe hemorrhagic cerebral venous sinus thrombosis (CVST).Methods:The clinical and imaging data of 5 consecutive patients with severe hemorrhagic CVST who received EMT combined with continuous intrasinus urokinase thrombolysis in Beijing Tiantan Hospital from March 2019 to February 2020 were retrospectively analyzed.Results:The average age of 5 patients was 39 years (range, 19-65 years). Two were males and 3 were females. Risk factors associated with CVST were identified in 3 patients. Four had more than two venous sinuses involved, with a total of 10 blood vessels affected by CVST. The affected venous sinus thrombus burden was high, the lesion volume was large, and the clinical manifestations were severe. The average duration of heparin anticoagulation therapy before EMT was 2.3 d (range, 0.5-7 d), and the average duration of intrasinus thrombolysis was 64 h (range, 30-95 h). After treatment, 1 vessel was completely recanalized and 7 vessels were partially recanalized. Four patients who achieved recanalization had good long-term clinical outcomes (modified Rankin Scale score: 0-2 at 3 months, 0-1 at 1 year). One patient failed to achieve recanalization and underwent decompressive craniectomy due to intracranial hypertension, had residual hemiparesis at 1-year follow-up. No procedure-related complications occurred.Conclusion:EMT combined with continuous intrasinus thrombolysis is a potential treatment option for patients with severe hemorrhagic CVST.

Objective? To expLore the diaLecticaL nursing abiLity and training among practice nursing students of TraditionaL Chinese Medicine coLLeges and universities so as to provide a reference for education reform and practice management of coLLeges and universities. Methods? In March 2018, we seLected 308 practice nursing undergraduates of schooL of nursing in Nanjing University of Chinese Medicine practicing at designated hospitaLs as subjects by purposive sampLing. ALL of them were investigated with the seLf-designed diaLecticaL nursing abiLity and training of practice nursing students of TraditionaL Chinese Medicine coLLeges and universities questionnaire. In this study, a totaL of 308 questionnaires were sent out and 254 vaLid questionnaires were coLLected. ResuLts? The scores of the diaLecticaL nursing abiLity of nursing students seLf-evaLuation questionnaire before and after practice were (4.91±1.90) and (4.72±1.92) respectiveLy with no statisticaL difference (t=1.379, P=0.170). Practice nursing students' master of diaLecticaL nursing basic knowLedge ranged from 69.29% to 89.76%. ConcLusions? Practice nursing students have the Low abiLity of diaLecticaL nursing. Practice hospitaLs shouLd improve the cuLtivate awareness and teaching LeveL, and satisfy nursing students' training needs so as to improve the diaLecticaL nursing abiLity of them.

Objective To investigate the correlation between incidence rate of tinnitus and noise exposure time,age,hearing condition in noise exposure workers.Methods A total of 1 985 noise exposure workers (age between 20～60 years old;working length between 1 ～30 years) in a large dockyard were randomly selected as the subject of this study with 1 831 male workers and 154 female workers in average 36.3±8.25 years old.The average noise exposure time was 9.1±6.50 years and pure tone threshold of final candidates in sound-proofed environment was evaluated (at 0.25～8 kHz).The subjects were divided into four groups according to the subjective tinnitus level:mild tinnitus,moderate tinnitus,severe tinnitus and no tinnitus to analysis the correlation among incidence rate of tinnitus and noise exposure time,age,hearing condition,etc.Results Among all 1 985 subjects enrolled the occurrence rate of tinnitus was 20.55％ (408/1 985),with 367 acquired mild tinnitus(89.95％),39 acquired moderate tinnitus (9.56％) and 2 for severe tinnitus (0.49％).Mild tinnitus and moderate tinnitus showed a multi-step raising according to noise exposure time.Mild tinnitus increased continually with age while moderate tinnitus showed an accumulation in age group over 55 years old.Female was less likely to be annoyed by tinnitus than male.Conclusion Tinnitus can be early warning of auditory damage by noise exposure;older male group with longer noise exposure time is more vulnerable to tinnitus.Tinnitus acquired in noise environment is more likely to be mild.
