Mufangji tang ameliorates pulmonary arterial hypertension through improving vascular remodeling,inhibiting inflammatory response and oxidative stress,and inducing apoptosis

Background:Mufangji tang(MFJT)is composed of Ramulus Cinnamomi,Radix Ginseng,Cocculus orbiculatus(Linn.)DC.,and Gypsum.In clinical settings,MFJT has been effectively employed in addressing a range of respiratory disorders,notably including pulmonary arterial hypertension(PAH).However,the mechanism of action of MFJT on PAH remains unknown.Methods:In this study,a monocrotaline-induced PAH rat model was established and treated with MFJT.The therapeutic effects of MFJT on PAH rat model were evaluated.Network pharmacology was conducted to screen the possible targets for MFJT on PAH,and the molecular docking between the main active components and the core targets was carried out.The key targets identified from network pharmacology were tested.Results:Results showed significant therapeutic effects of MFJT on PAH rat model.Analysis of network pharmacology revealed several potential targets related to apoptosis,inflammation,oxidative stress,and vascular remodeling.Molecular docking showed that the key components were well docked with the core targets.Further experimental validation results that MFJT treatment induced apoptosis(downregulated Bcl-2 levels and upregulated Bax levels in lung tissue),inhibited inflammatory response and oxdative stress(decreased the levels of IL-1β,TNF-α,inducible NOS,and malondialdehyde,and increased the levels of endothelial nitric oxide synthase,nitric oxide,glutathione and superoxide dismutase),reduced the proliferation of pulmonary arterial smooth muscle cells(downregulated ET-1 andβ-catenin levels and ERK1/2 phosphorylation,increased GSK3βlevels).Conclusion:Our study revealed MFJT treatment could alleviate PAH in rats via induction of apoptosis,inhibition of inflammation and oxidative stress,and the prevention of vascular remodeling.

Therapeutic effect of San Bi Tang combined with glucosamine sulfate capsules in cold-dampness-type knee osteoarthritis

BACKGROUND Cold-dampness-type knee osteoarthritis is a common middle-aged and elderly disease,but its pathogenesis is not fully understood,and its clinical treatment has limitations.Glucosamine sulfate capsules are commonly used for treating arthritis,and San Bi Tang is a classic formula of traditional Chinese medicine(TCM)that has the effects of warming yang,dispelling dampness,relaxing muscles,and activating collaterals.This research hypothesized that the combination of modified San Bi Tang and glucosamine sulfate capsules could enhance the clinical efficacy of treating cold-dampness-type knee osteoarthritis through complementary effects.AIM To analyze the clinical efficacy of San Bi Tang combined with glucosamine sulfate capsules when treating cold-dampness-type knee osteoarthritis.METHODS A total of 110 patients with cold-dampness-type knee osteoarthritis were selected as research subjects and randomly divided into a control group and an experimental group of 55 cases each.The control group received only treatment with glucosamine sulfate capsules,while the experimental group received additional treatment with modified San Bi Tang for a duration of 5 wk.The patients’knee joint functions,liver and kidney function indicators,adverse reactions,and vital signs were evaluated and analyzed using SPSS 26.0 software.RESULTS Before treatment,the two groups’genders,ages,and scores were not significantly different,indicating comparability.Both groups’scores improved after treatment,which could indicate pain and knee joint function improvement,but the test group had better scores.The TCM-specific symptoms and the clinical efficacy of the treatment in the test group were higher.Before and after treatment,there were no abnormalities in the patients’liver and kidney function indicators.CONCLUSION The combination of modified San Bi Tang and glucosamine sulfate capsules is superior to treatment with sulfated glucosamine alone and has high safety.

Anti-inflammatory effects of Tao Hong Si Wu Tang in mice with lung cancer and chronic obstructive pulmonary disease

BACKGROUND Lung cancer(LC)combined with chronic obstructive pulmonary disease(COPD)is a common combination of comorbidities.Anti-inflammation and modulation of oxidative/antioxidative imbalance may prevent COPD-induced LC,and are also crucial to the treatment of LC combined with COPD.Modern studies have shown that Tao Hong Si Wu Tang(THSW)has vasodilatory,anti-inflammatory,anti-fatigue,anti-shock,immunoregulatory,lipid-reducing,micronutrient-supplementing,and anti-allergy effects.AIM To observe the effects of THSW on COPD and LC in mice.METHODS A total of 100 specific pathogen-free C57/BL6 mice were randomly divided into five groups:Blank control group(group A),model control group(group B),THSW group(group C),IL-6 group(group D),and THSW+IL-6 group(group E),with 20 mice in each group.A COPD mouse model was established using fumigation plus lipopolysaccharide intra-airway drip,and an LC model was replicated by in situ inoculation using the Lewis cell method.RESULTS The blank control group exhibited a clear alveolar structure.The model control and IL-6 groups had thickened alveolar walls,with smaller alveolar lumens,interstitial edema,and several inflammatory infiltrating cells.Histopathological changes in the lungs of the THSW and THSW+IL-6 groups were less than those of the model control group.The serum IL-1β,IL-6,and TNF-αlevels and IL-6R,JAK,p-JAK,STAT1/3,p-STAT1/3,FOXO,p-FOXO,and IL-7R expression levels in lung tissues of mice in the rest of the groups were significantly higher than those of the blank control group(P<0.01).Compared with the model control group,the IL-6 group demonstrated significantly higher levels for the abovementioned proteins in the serum and lung tissues(P<0.01),and the THSW group had significantly higher serum IL-1β,IL-6,and TNF-αlevels and IL-7R expression levels in lung tissues(P<0.01)but significantly decreased IL-6R,JAK,p-JAK,STAT1/3,p-STAT1/3,FOXO,p-FOXO,and IL-7R levels(P<0.01).CONCLUSION THSW reduces the serum IL-1β,IL-6,and TNF-αlevels in the mouse model with anti-inflammatory effects.Its antiinflammatory mechanism lies in inhibiting the overactivation of the JAK/STAT1/3 signaling pathway.

Gaze and Oppositional Gaze in Mr. Tang’s Girls

The gaze is a means of power that can flow through family relationships.It has intense regulatory overtones.In her short story Mr.Tang’s Girls,Malaysian-Chinese Anglophone diasporic writer Shirley Geok-lin Lim shows the conflict between Eastern and Western cultures and the resistance of women under the oppression of patriarchy through the portrayal of the father,Ah Kong,and the eldest daughter,Kim Li.Based on Foucault’s discipline gaze and Hooks’oppositional gaze,this article analyzes the power operation in the story from the following three aspects:the male gaze,discipline and self-discipline,and the oppositional gaze.Kim Li’s subjective image of breaking free from male ownership control has been presented.It suggests the difficulties encountered by female groups in their rebellion against the male gaze and their pursuit of freedom and emancipation.It also reflects the tragedy of awakening women’s destinies under the dual oppression of patriarchy and the East-Westen cultural conflict.

唐朝马球运动军事功用的历史探赜

回溯马球运动在大唐王朝的兴盛繁荣历程,探究马球在训练提升军队骑兵战力方面的价值功用,有助于从一个侧面或者视角审视一项体育运动对唐王朝军事武备与尚武风气的深远影响。运用历史考证、文本分析等方法,从文物、文献与文化遗存等证据链互补的视角展开论证。研究认为,马球由我国古代蹴鞠演变而来,繁荣兴盛于唐朝并逐渐形成完备的训练与竞赛体系。唐朝时期国家富强、社会稳定和文化繁荣,为马球在朝野广泛开展奠定了物质与文化基础,而其间不断发生的战事与外敌威胁,也为马球成为军队训练将士的重要手段提供了条件。结论显示,作为一项竞技性很强的运动项目,马球不仅是王公贵族和民众娱乐之戏,还是军队骑兵的重要科目。唐朝军中经常举行马球比赛活动,因此在增强士兵体能素质与马上对敌作战技巧,提高骑兵之骑术和马上砍杀技术,锻炼马匹作战对抗与奔袭能力等方面具有鲜明的军事功能,同时在塑造整个社会尚武精神、增进唐朝军事外交、增进中西文化交流等方面亦发挥了重要作用。

唐朝初期中原与吐蕃佛教交融依存语境解读

吐蕃与唐朝因中原佛教结缘,而双方的交融依存发端于唐朝重启了儒家孟子性善论仁道思想,摒弃了过去天赋神权论的儒家思想。儒学扬弃之后在唐朝初期强调“仁”道,唐朝因“仁”和合吐蕃,佛教的中国化也在唐朝初期有了新的面目:“提倡众生平等”。儒学的“仁”转化为佛学的“众生平等”理念,形成了吐蕃与中原的基本交往范式,即以佛教为抓手,而以借鉴唐朝的基本思想为内容的事实。这也说明佛教在唐朝真正开始中原化了,而佛教在吐蕃还远未开始吐蕃化,文成公主入藏意味着吐蕃与中原启动了交往交流交融的加速模式。

唐朝“大一统”的空间叙事——基于《新唐书·地理志》的研究

“大一统”是中国学术界的重要议题,但对唐朝“大一统”的讨论,现有研究主要是从思想阐释层面展开,从空间叙事角度表达唐朝“大一统”历史形态的研究不多。《新唐书·地理志》对唐朝疆域范围、交通道路、户数人口、政区沿革等方面的详细记载为我们解释唐朝“大一统”提供了空间维度的观察路径与文献基础。唐朝“郡县天下-羁縻府州-文化边疆”的空间结构不仅改变了秦汉以来的“大一统”空间叙事,而且在具体实践上,唐朝所形成的“大一统”是沟通中央与地方、维系中心与边疆、涵盖中国境内与域外世界的整体性叙事。正是基于“大一统”的空间叙事,使得中国疆域具有了超越具体朝代的稳定性,成为现代中国疆域叙事体系的重要内容之一。

后唐明宗朝北面行营与北部边防

北面行营的设置,是唐明宗措置军事的一项重要措施。在平定叛乱时,北面行营的主导力量是唐明宗亲信与元随以及中央的禁军。行营统帅的设置,体现了分权与制衡的原则。北面行营运行体现了唐明宗时期中央权力的发展,以及战时状态下唐明宗对于军事的掌控意愿。在战争结束后,北面行营成为后唐措置北边防御的重要机构。行营制衡的原则也运用在边防体系的构建之上,并与唐明宗的对外政策互为照映。在行营之内,唐明宗通过任命来自不同政治势力的行营统帅,派遣禁军出戍的方式,来实现行营权力的互相制衡。在后唐北部边防体系中,唐明宗设置北面行营署理河北边防,以期与负责河东边防的河东节度使实现军事上的互相制衡。但在北面行营的实际运行中,由于唐末帝时期中央激烈的政治变动以及契丹突然的军事介入,其军事上的平衡作用逐步丧失。北面行营反而成为赵德钧拥兵谋夺天下的资本。北面行营的运行反映了唐宋时期边防体制演进中对军事权力分割与制衡的趋势。
