Objective To observe the clinical efficacy of toripalimab combined with bronchial ar-terial chemoembolization(BACE)and intensity-modulated radiotherapy(IMRT)in advanced lung cancer.Methods A prospective single-arm trial was conducted in 104 patients with programmed death-ligand 1(PD-L1)-positive,driver gene-negative non-small cell lung cancer(NSCLC)in stages of Ⅲ B to Ⅳ admitted to the First People's Hospital of Guangyuan City of Sichuan Province.All patients received toripalimab combined with BACE and IMRT.Clinical efficacy,symptom improve-ment time,tumor biomarker levels[carcinoembryonic antigen(CEA),carbohydrate antigen 199(CA199),cytokeratin 19 fragment(CYFRA21-1),neuron-specific enolase(NSE)],T-lymphocyte subsets(CD3+,CD4+,CD4+/CD8+),survival outcomes,and adverse events were analyzed.Results Among 102 patients,the objective response rate(ORR)was 75.49％,disease control rate(DCR)was 90.20％,survival rate was 68.63％,and 12-month progression-free survival rate was 62.75％.The overall incidence of adverse events of any grade was 72.55％.Post-BACE,post-IMRT,and post-toripalimab treatment levels of CEA,CYFRA21-1,CA199,and NSE were significantly lower than baseline data(P＜0.05),with the lowest levels observed after toripalimab treatment compared to post-BACE and post-IMRT(P＜0.05).CD3+,CD4+,and CD4+/CD8+decreased after BACE,IMRT and toripalimab therapy,but they were increased following toripalimab therapy compared with the other two therapies(P＜0.05).Conclusion Toripalimab combined with BACE and IMRT demonstrates significant clinical efficacy and acceptable tolerability in PD-L1-positive,driver gene-negative NSCLC in stages of ⅢB to Ⅳ,serving as a preferred consolidation regimen after unresect-able chemoradiotherapy.

Background: and Purpose Essential tremor with a midline distribution (Mid-ET) may represent a distinct subtype of essential tremor (ET) that primarily affects midline structures, often indicating advanced disease stage and increased severity. Recent studies have highlighted the complexity of Mid-ET, but research on neurological soft signs (NSS) in Mid-ET remains insufficient. Methods: The patients with ET included in this cross-sectional study were divided into two subgroups based on whether or not the ET had a midline distribution: Mid-ET and No-MidET. Comparative analyses were performed to assess clinical features and NSS prevalence in these subgroups. Results: Among 1,160 patients, 567 (48.9%) were Mid-ET and 593 (51.1%) were No-Mid-ET.The prevalence rates of head, face (including the jaw), and voice tremors were 31.9%, 23.0%, and 25.8%, respectively. In Mid-ET, tremor often affects multiple midline structures simultaneously. In the entire cohort, 24.7%, 16.6%, and 7.6% of patients exhibited tremors in one, two, and three midline structures, respectively. The prevalence of common NSS, including mild cognitive impairment, impaired tandem gait, and questionable dystonic posturing, was significantly higher in the Mid-ET than the No-Mid-ET subgroup (all p<0.001). Furthermore, we found that female sex (p<0.001), olfactory dysfunction (p=0.003), and questionable dystonic posturing (p=0.004) were associated with Mid-ET. Conclusions Mid-ET and No-Mid-ET presented significant clinical differences. The presence of questionable dystonic posturing may contribute to the distinct characteristics of Mid-ET, suggesting the presence of pathophysiological differences between the subgroups. Further investigations are warranted to determine the potential pathophysiological link between NSS and Mid-ET.

Objective:To explore the efficacy and safety of needle knife combined with local injection of compound betamethasone in the treatment of truncal keloids.Methods:A total of 56 patients with truncal keloids were prospectively enrolled from the Affiliated Hospital of Hangzhou Normal University from May 2022 to May 2024. Among them, there were 27 males and 29 females, aged 20-45 (31.5±6.6) years. The disease duration was 12.0 (9.0, 14.0) months. The area of keloids was (6.9±3.0) cm2, and the thickness was (3.8±0.7) mm. The 56 patients had a total of 62 truncal keloids. The etiological factors included injury or surgery (26 keloids), infection (6 keloids), and unknown causes (30 keloids). The locations of keloids were the chest (43 keloids), abdomen (11 keloids), and shoulders/back (8 keloids). Patients were divided into experimental group and control group using a random number table. The experimental group (27 patients with 29 keloids) received combined treatment of local compound betamethasone injection and needle knife therapy. The control group (29 patients with 33 keloids) received local compound betamethasone injection only. The Vancouver scar scale (VSS) was used to score keloids before the treatment and at 1, 3, 6 months after the treatment. Meanwhile, patients were instructed to score the pain and pruritus symptoms of their keloids using the visual analogue scale (VAS). At 6 months after the start of treatment, the incidence of adverse reactions and recurrence rate were calculated, and patient satisfaction was evaluated.Results:Intra-group comparison showed that the VSS and VAS scores of both groups at 1, 3, 6 months after the treatment were statistically significantly different from those before the treatment (all P<0.05). Inter-group comparison revealed no statistically significant differences in VSS and VAS scores between the two groups before the treatment (all P>0.05). At 1 month after the treatment, there was no statistically significant difference in VSS scores between the two groups ( P=0.515), but the VAS score of the experimental group was lower than that of the control group ( P=0.008). At 3 and 6 months after the treatment, both VSS and VAS scores of the experimental group were lower than those of the control group (all P<0.05). In the experimental group, 1 case of hypopigmentation occurred, with an adverse reaction rate of 3.4% (1/29). In the control group, 1 case of hypopigmentation and 1 case of mild depression occurred, with an adverse reaction rate of 6.1% (2/33); the difference between the two groups was not statistically significant ( P=1.000). The recurrence rates of the experimental group and the control group were 58.6% (17/29) and 69.7% (23/33), respectively, with no statistically significant difference ( P=0.363). The satisfaction scores of the experimental group and the control group were (85.6±6.7) and (78.3±9.4) scores, respectively, and the difference was statistically significant ( P=0.002). Conclusion:Needle knife combined with local injection of compound betamethasone has good efficacy in the treatment of truncal keloids, with a low incidence of adverse reactions and high patient satisfaction.

Objective:To explore the effects of type D personality on mild cognitive dysfunction (MCI) in patients with coronary heart disease and the multiple mediating roles of dietary inflammation index (DII) and systemic immune inflammation index (SII) between type D personality and MCI.Methods:A cross-sectional study was used. A total of 321 patients diagnosed with coronary heart disease by coronary angiography in the Second Affiliated Hospital of Harbin Medical University from May 2022 to March 2023 were selected as the study objects by convenient sampling method. General Information Questionnaire, Type-D Personality Scale-14, Montreal Cognitive Assessment, and Semi-Quantitative Food Frequency Questionnaire were employed for data collection. DII and SII were used to evaluate dietary inflammatory potential and systemic inflammatory status, respectively. Structural equation modeling was utilized to analyze the mediating effectsamong type D personality, DII, SII and MCI.Results:A total of 306 valid questionnaires were collected. Among the 306 patients, there were 215 males (70.3%) and 91 females (29.7%), aged 27-70 (59.24 ± 9.16) years old. The structural equation model showed that type D personality could directly influence MCI (effect size = - 1.098, 95% CI - 1.869 - - 0.327), and could also mediate the occurrence of MCI in coronary heart disease patients through the single mediation of DII (effect size = - 0.374, 95% CI - 0.644 - - 0.128) and SII (effect size = - 0.450, 95% CI - 0.806 - - 0.132), as well as the chain mediation of DII and SII (effect size = - 0.146, 95% CI - 0.293 - - 0.027). Conclusions:Type D personality, DII and SII can affect the occurrence of MCI in CHD patients, and DII and SII play multiple mediating roles between type D personality and MCI in patients with coronary heart disease. Clinical and community nurses can improve the unhealthy dietary behavior, reduce the level of inflammation and delay the occurrence and development of MCI by early screening of type D personality in patients with coronary heart disease.
