Objective: To assess the outcomes after acupoint application in patients with pharyngeal pain in a real-world settings, and analyze the characteristics of effective population and prescription characteristics of acupoint application. Methods: Based on CHUNBO platform, patients with pharyngeal pain who were candidates for acupoint application on the basis of physician-evaluation, were enrolled in a nationwide, prospective, 69-week multicenter observational study from August 2020 to February 2022. Propensity score matching(PSM) was used to match the confounding factors and the association rules were used to analyze the characteristics of effective population and prescription characteristics of acupoint application. Outcome assessments included the disappearance rate of pharyngeal pain(within 3, 7, and 14 days), disappearance time of pharyngeal pain, as well as adverse events. Results: Of 7,699 enrolled participants, 6,693(86.9%) received acupoint application and 1,450(21.7%) with non-acupoint application. After PSM, there were 1,004 patients each in the application group(AG) and non-application group(NAG). The disappearance rate of pharyngeal pain in the AG at 3, 7, and 14 days were all higher than those in the NAG(P<0.05). The disappearance time of pharyngeal pain in the AG were shorter than that in the NAG(logrank P<0.001, hazard ratio=1.51, 95% confidence interval: 1.41–1.63). The median age of effective cases was 4 years, mainly 3–6 years old(40.21%). The disappearance rate of pharyngeal pain in the application group with tonsil diseases was 2.19 times higher than that in the NAG(P<0.05). The commonly used acupoints for the effective cases were Tiantu(RN 22), Shenque(RN 8) and Dazhui(DU 14). The commonly used herbs for the effective cases were Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae. Among them, Natrii sulfas was applied to RN 8 most frequently(support 84.39%). A total of 1,324(17.2%) patients experienced AEs, and mainly occurred in the AG, with s

In the Ruhrstahl-Heraeus （RH） refining process, liquid steel flow pattern in a ladle is controlled by the fluid flow behavior in the vacuum chamber. Potassium chloride solution and NaOH solution saturated with CO2 were respectively used as a tracer to investigate the liquid and gas flow behaviors in the vacuum chamber. Principal compo nent and comparative analysis were made to show the factors controlling mixing and circulation flow rate. The liquid level and bubble behavior in the vacuum chamber greatly affect fluid flow in RH process. Experiments were performed to investigate the effects of liquid steel level, gas flow rate, bubble residence time, and gas injection mode on mixing, decarburization, and void fraction. The results indicate that the mixing process can be divided into three regions： the flow rate affected zone, the concentration gradient-affected zone, and their combination. The liquid steel level in the vacuum chamber of 300 mm is a critical point in the decarburization transition. For liquid level lower than 300 mm, liquid steel circulation controls decarburization, while for liquid level higher than 300mm, bubble behavior is the main controlling factor. During the RH process, it is recommended to use the concentrated bubble injection mode for low gas flow rates and the uniform bubble injection mode for high gas flow rates.

背景:细胞焦亡参与软骨细胞外基质降解、滑膜炎症以及疼痛,在骨关节炎防治中发挥重要作用。此外,运动可通过抑制细胞焦亡调控骨关节炎的发生,已成为防治骨关节炎的研究热点。目的:总结细胞焦亡在骨关节炎中的调控作用,以及运动介导细胞焦亡在改善骨关节炎中的机制。方法:以“pyroptosis,osteoarthritis,chondrocyte pyroptosis,synovial cell pyroptosis,exercise”和“细胞焦亡,骨关节炎,软骨细胞焦亡,滑膜细胞焦亡,运动”为关键词,检索PubMed与中国知网数据库1992-2024年间发表的相关文献,根据纳入及排除标准选择71篇文献进行综述。结果与结论:①骨关节炎是以软骨细胞外基质降解、滑膜炎症和软骨下骨重塑等为特点的慢性退行性关节疾病,易引起骨的器质性病变、疼痛并引发功能障碍。②细胞焦亡作为一种特殊的程序性死亡机制,其特征为细胞裂解死亡释放炎症因子引发强烈的炎症反应,与骨关节炎的发生发展关系密切。细胞焦亡可导致大量炎症因子释放,进而激活核因子κB转录,增加焦亡蛋白的产生,进而加剧骨关节炎的发生发展,因此细胞焦亡可作为骨关节炎防治的新方向。③运动可通过下调焦亡蛋白信号通路和抑制相关炎症因子表达等途径抑制软骨细胞和滑膜细胞的焦亡,从而在骨关节炎防治中发挥重要作用。有氧和无氧运动可通过抑制细胞焦亡的发生延缓骨关节炎的病理进程,中等强度的有氧运动通过抑制细胞焦亡信号通路改善骨关节炎的效果较好,无氧运动可通过提高肌肉质量进而对骨关节炎产生有益效应。

In non-small cell lung cancers,the non-squamous and squamous subtypes（nsqNSCLC and sqNSCLC） exhibit disparities in pathophysiology,tumor immunology,and potential genomic correlates affecting responses to immune checkpoint inhibitor（ICI）-based *** our inhouse training cohort（n=85）,the presence of the LRP1B deleterious mutation（LRP1B-del） was associated with longer and shorter progression-free survival（PFS） on ICIs alone in nsqNSCLCs and sqNSCLCs,respectively(Pinteraction=0.008).These results were validated using a larger public ICI cohort(n=208,Pinteraction<0.001).Multiplex immunofluorescence staining revealed an association between LRP1B-del and increased and decreased numbers of tumor-infiltrating CD8+T cells in nsqNSCLCs（P=0.040） and sqNSCLCs（P=0.014）,*** the POPLAR/OAK cohort,nsqNSCLCs with LRP1B-del demonstrated improved PFS benefits from atezolizumab over docetaxel(hazard ratio（HR）=0.70,P=0.046),whereas this benefit was negligible in those without LRP1B-del（HR=1.05,P=0.64）.Conversely,sqNSCLCs without LRP1B-del benefited more from atezolizumab（HR=0.60,P=0.002） than those with LRP1B-del（HR=1.30,P=0.31）.Consistent results were observed in the in-house CHOICE-01 cohort,in which nsqNSCLCs with LRP1B-del and sqNSCLCs without LRP1B-del benefited more from toripalimab plus chemotherapy than from chemotherapy alone(Pinteraction=0.008).This multi-cohort study delineates the antithetical impacts of LRP1B-del in nsqNSCLCs and sqNSCLCs on predicting the benefits from ICI alone or with chemotherapy over chemotherapy *** findings highlight the distinct clinical utility of LRP1B-del in guiding treatment choices for nsqNSCLCs and sqNSCLCs,emphasizing the necessity for a detailed analysis based on pathological subtypes when investigating biomarkers for cancer therapeutics.

利用多重网格预条件共轭梯度法,研究了囚禁在二维光晶格与谐振势组成的复合势阱中的旋转玻色-爱因斯坦凝聚体中的涡旋分布,探讨了光晶格深度、晶格常数和凝聚体旋转频率对旋转凝聚体中涡旋分布的影响.结果表明,由于光晶格势阱的引入,凝聚体中产生涡旋,且涡旋位于外部势阱极小值处.随着光晶格势阱深度的增加,凝聚体集聚在光晶格势阱的底部,形成格点状分布,其中的涡旋形成涡旋对,并融合形成更大的涡旋.在晶格常数较小时,凝聚体中涡旋分布形成类似Abrikosov涡旋晶格,随着晶格常数的增加,凝聚体中涡旋的分布形式出现多样化,出现了内中外三层结构.随着旋转频率的增加,凝聚体中涡旋数目也随之增加,涡旋分布也更加复杂和富于变化,凝聚体密度分布范围也随着旋转频率的增加而扩展.当凝聚体旋转频率接近外部谐振势阱的谐振频率,即凝聚体处于最低朗道能级近似时,其中的涡旋数量大幅度增加,且出现涡旋成对组合与融合现象,并形成了涡旋斑图花纹.
