Platelets are indispensable for physiological hemostasis and pathological thrombus formation, and platelet adhesion to endothelial collagen is a critical initial step in thrombus formation, often overlooked in current antiplatelet therapies. This study aims to elucidate how ginsenoside CK enhances hemodynamic circulation, alleviates stasis, and proposes therapeutic mechanisms. Inspired by the effects on improving microcirculatory disturbances in an acute soft tissue injury model, CK was identified as a PHD2 inhibitor, effectively suppressing platelet adhesion to collagen. It was proposed that targeting PHD2 regulates collagen hydroxylation modification, thereby influencing the formation of its three-dimensional structure, reducing the binding affinity between VWF and collagen, and ultimately suppressing thrombotic events. The efficacy of this mechanism was subsequently confirmed through a mouse DIC model, demonstrating the feasibility of CK in alleviating circulatory disorders. It is worth noting that when Phd2 was knocked down in mice's lungs, pulmonary embolism was significantly reduced. Additionally, PHD2 inhibitors approved for other diseases have exhibited similar anti-thrombotic effects. Moreover, when PHD2 inhibitors were combined with aspirin, they more effectively inhibited arterial thrombosis in rats. The findings offer valuable insights into potential targets for developing antiplatelet drugs or expanding therapeutic applications for existing PHD2 inhibitors in treating thrombotic diseases.

Sustained inflammatory responses are closely related to various severe diseases, and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment. Natural products have garnered considerable concern for the treatment of inflammation. Huanglian-Wumei decoction (HLWMD) is a classic prescription used for treating inflammatory diseases, but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated. Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory, we successfully obtained berberine (BBR)-chlorogenic acid (CGA) supramolecular (BCS), which is an herbal pair from HLWMD. Using a series of characterization methods, we confirmed the self-assembly mechanism of BCS. BBR and CGA were self-assembled and stacked into amphiphilic spherical supramolecules in a 2:1 molar ratio, driven by electrostatic interactions, hydrophobic interactions, and π-π stacking; the hydrophilic fragments of CGA were outside, and the hydrophobic fragments of BBR were inside. This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules. Compared with free molecules, BCS significantly attenuated the release of multiple inflammatory mediators and lipopolysaccharide (LPS)-induced pyroptosis. Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB (NF-κB) p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase-11.

Healthy lifestyles and good living habits are effective strategies and important approaches to prevent chronic non-communicable diseases. With the development of evidence-based medicine, the evidence translation system has made some achievements in clinical practice. There is, however, no comprehensive, professional and efficient system for translating lifestyle evidence globally. Therefore, the Health Lifestyle Evidence (HLSE) Group of Lanzhou University constructed the HLSE Evidence Translation System (https://hlse.cn/), with the aim of synthesizing, evaluating, translating, and applying lifestyle-related evidence resources. This paper aims to introduce the functional module design of the evidence translation system, the system development process and testing, introduce the interface design and function demonstration, and explain the significance of constructing the HLSE.

Adaptive design, with advantages such as dynamically adjusting trial plans, reducing resource waste, and improving trial efficiency, has broken through the competitive situation of new drug development and gradually met the needs of clinical research. In recent years, the use of adaptive design in platform trials as an innovative research model has added impetus to new drug development. This article outlines the research progress, contents and characteristics, common design types, statistical analysis, and case interpretation of adaptive design, and introduces the concept, types, and applications of adaptive platform trials, with the hope of providing scientific reference for further exploration of clinical trials and new drug development.

Objective To observe the effects of grain-sized moxibustion on Th1 cell/Th2 cell(Th1/Th2)balance and transcription factors T-box transcription factor(T-bet)and GATA binding protein 3(GATA3)in immunosuppressive mice induced by chemotherapy.Methods According to the random number table method,32 SPF male CD-1(ICR)mice were randomly divided into the normal group,model group,levamisole hydrochloride group,and grain-sized moxibustion group,with eight mice per group.Except for the normal group,the immunosuppressive model was established by intraperitoneal injection of cyclophosphamide(80 mg/kg,once daily for three consecutive days).Mice in the levamisole hydrochloride group were given levamisole hydrochloride solution(10 mg/kg)by gavage.Mice in the grain-sized moxibustion group was given grain-sized moxibustion at"Guanyuan"(CV4),bilateral"Zusanli"(ST36),and bilateral"Sanyinjiao"(SP6),with three Zhuang at each acupoint for approximately 30 s each.The intervention was administered once daily for seven consecutive days.The general condition of mice was observed.The spleen mass and spleen index were detected.The pathological changes of spleen tissue were observed by HE staining.The protein and mRNA expressions of T-bet,GATA3,interferon-γ(IFN-γ),and interleukin(IL)-4 in spleen tissue of mice were detected by Western blotting and real-time PCR.The contents of IFN-γ,IL-2,and IL-4 in serum of mice were detected by enzyme-linked immunosorbent assay.Results Compared with the normal group,the mice in the model group were slow in response,unstable in gait;the spleen weight and spleen index were increased(P<0.05);the structure of spleen tissue was disordered,the mRNA and protein expressions of T-bet and IFN-γ in spleen tissue were decreased,and the mRNA and protein expressions of GATA3 and IL-4 were increased(P<0.05);the contents of IFN-γ and IL-2 in serum were decreased,and the content of IL-4 was increased(P<0.05).Compared with the model group,the general condition of mice in the levamisole hydrochloride group and the grain-sized moxibustion group was improved,the structure of spleen tissue was improved,the mRNA and protein expressions of T-bet and IFN-γ in spleen tissue were decreased,and the mRNA and protein expressions of GATA3 and IL-4 were increased(P<0.05);the contents of IFN-γ and IL-2 in serum were decreased,and the content of IL-4 was increased(P<0.05).Conclusion Grain-sized moxibustion can significantly improve the immunosuppressive symptoms induced by chemotherapy.The mechanism may be through regulating the expressions of transcription factors T-bet and GATA3,regulating Th1/Th2 balance,and thus restoring the immune balance.

Objective: To investigate the clinicopathological features, immunophenotype, ultrastructure, genetic alterations and prognosis of succinate dehydrogenase-deficient renal cell carcinoma (SDH RCC). Methods: A total of 11 SDH RCCs, diagnosed from 2010 to 2019, were selected from the Department of Pathology of Nanjing Jingling Hospital, Nanjing University School of Medicine for clinicopathologic, immunohistochemical (IHC), ultrastructural investigation and follow-up. The molecular features of seven cases were analyzed by the panel-targeted DNA next generation sequencing (NGS). Results: There were seven males and four females, with ages ranging from 24 to 62 years (mean 41.4 years, median 41 years). Microscopically, SDH RCC was mainly composed of solid and tubular structures with local cystic change. Four cases showed nested or trabecular structure distributed in a loose hypocellular connective tissue or around scar, similar to oncocytoma. The neoplastic cells demonstrated flocculent eosinophilic cytoplasm with typical intracytoplasmic vacuoles. Immunohistochemically, eight cases were negative for SDHB; three cases showed focal and weak expression, whereas normal renal tubular and vascular endothelial cells demonstrated strong cytoplasmic staining. NGS of DNA targeted-panel detected pathogenic mutations of SDHB gene in seven cases (including three cases with equivocal IHC expression of SDHB), without any mutations in other SDH related genes. There were four cases of SDHB missense mutation, one case of frameshift mutation, one case of splicing mutation, and one case of acquired stop codon mutation. Conclusions: SDH RCC is a distinct variant of RCCs with genetic tendency or with hereditary cancer syndrome. NGS is recommended to detect the related gene mutations for a definitive diagnosis. The patients should be closely followed up.
