Intravascular large B-cell lymphoma(IVLBCL) is a rare and aggressive type of lymphoma with diverse and nonspecific clinical manifestations, often leading to misdiagnosis. This article reports a case of IVLBCL in a middle-aged male patient who initially presented with pulmonary arterial hypertension(PAH). The patient exhibited progressive hypoxemia and PAH, showing poor response to standard PAH therapy. Laboratory tests indicated a hyperinflammatory state and significantly elevated lactate dehydrogenase levels, while imaging revealed diffuse bilateral lung lesions. Random skin biopsy identified atypical B lymphocytes within subcutaneous capillaries, confirming the diagnosis of IVLBCL. Following treatment with the ZR-CHOP regimen, the patient's symptoms and laboratory parameters improved markedly. By reviewing relevant literature, this article systematically outlines the diagnostic and therapeutic process of this case, aiming to provide insights for the clinical recognition of such rare presentations.

To systematically analyzed the reporting status of core elements in publicly available clinical practice guideline(hereafter referred to as "guideline") protocols published domestically and internationally over the past decade, identified existing problems, and provided evidence to inform the standardized writing and publication of future guideline protocols. A systematic search was conducted in Chinese and English databases for clinical practice guideline protocols published during the past ten years. The basic characteristics and reporting of core elements—including registration information, conflict of interest management, evidence grading, development process and timeline planning, as well as dissemination and implementation—were extracted and analyzed. Chi-square tests were performed to explore associations between protocol characteristics and the reporting of core elements. A total of 94 guideline protocols were included, of which 67 were in Chinese(71.28%) and 27 were in English(28.72%). Overall, 82.98% of the guideline protocols were registered, 92.55% reported management of conflicts of interest, 97.87% reported evidence searching, 88.30% reported evidence grading, and 89.36% described dissemination and implementation strategies. However, only 55.32% reported the guideline development process, and merely 23.40% reported timeline planning. Further analysis indicated that the reporting of registration, evidence searching, development process, and timeline planning was associated with year of publication. Differences were observed between domestic and international guidelines in reporting registration, conflict of interest management, development process, time planning, and dissemination and implementation. Guidelines intended for development exhibited higher reporting rates for registration, development process, and dissemination and implementation compared to those planned for updating or adaptation. Although current guideline protocols demonstrate relatively adequate reporting of methodological elements, deficiencies remain in development process and timeline planning. Future efforts should focus on promoting the publication and standardized reporting of guideline protocols, enhancing the international recognition of registration platforms, and strengthening the development process and timeline planning to advance the scientific rigor and transparency of guideline development.

Intestinal barrier damage is a prominent feature of non-alcoholic fatty liver disease (NAFLD) and serves as a critical factor driving the progression from simple fatty liver to non-alcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. The "turbid pathogenic factors entering the blood" theory integrates classical traditional Chinese medicine (TCM) principles with contemporary disease evolution trends and research findings. It posits that endogenous turbid pathogenic factors within the body infiltrate the blood vessels, leading to impure and viscous blood quality, thereby triggering various diseases. Based on this theory, this article elucidated the pathogenic mechanism of NAFLD-associated intestinal barrier damage. It argued that in NAFLD, the liver loses its dredging function, and the spleen becomes obstructed and dysfunctional. Moreover, essential nutrients fail to be properly transformed, resulting in the internal generation of turbid pathogenic factors. This subsequently initiates a series of pathological changes, namely, "infiltration of phlegm-turbidity into the blood, eroding the intestinal mucosa", "infiltration of glucose-turbidity into the blood, macerating and eroding the intestinal mucosa", "infiltration of heat-turbidity into the blood, scorching and eroding the intestinal mucosa", and "infiltration of stasis-turbidity into the blood, stagnating and eroding the intestinal mucosa", ultimately causing intestinal barrier damage. Furthermore, guided by the "turbid pathogenic factors entering the blood" theory, this article explored TCM intervention strategies: employing medicinals targeting the liver meridian to address the root cause and reduce the generation and deposition of turbid pathogenic factors in the liver, administering blood-system medicinals to clear the blood and purge turbidity, thereby intercepting the progression of the disease mechanism, and applying tonifying medicinals to bolster healthy Qi and defend against turbid invasion, allowing the damaged intestinal mucosa to gradually heal. This article presented novel theoretical and medicinal perspectives for analyzing NAFLD-associated intestinal barrier damage based on the "turbid pathogenic factors entering the blood" theory, aiming to provide new entry points and broader horizons for related research and clinical practice.

The chapter Zhouyu in Guoyu says "Qi of the heaven and the earth moves without losing its order." With lucidity ascending and turbidity descending, Qi moves in a normal state, and Yin and Yang consolidate the foundation of the body. The mutual interference between lucidity and turbidity leads to the disorder of Qi movement, thus causing diseases. It is a pathological state of disorder between ascending and descending, as well as between entering and exiting, gradually evolving into a state of turbidity affecting lucidity and transforming into pathogen, which can be used to interpret and analyze the core of disease pathogenesis. The theory of lucidity and turbidity is connected with the harmony of nutrient and defensive aspects, Qi circulation, and sweat pore associating with Qi movement, and it has common implications with immune responses and nutrient metabolism system, intestinal mucosal barrier function, and mitochondrial energy synthesis. Modern studies have shown that intestinal flora imbalance, bile acid receptor inactivation, macrophage polarization imbalance, epithelial-mesenchymal transition, ferroptosis and other related microscopic pathological mechanisms are involved in the development and progression of ulcerative colitis. By delving into the common meaning of the classic theory of mutual interference between lucidity and turbidity in traditional Chinese medicine and modern medical pathological mechanisms, this paper summarizes the correspondence between the micropathological mechanism and the theory of mutual interference between lucidity and turbidity in the regulation and mamagement of ulcerative colitis. The combined use of sweet and warm medicinal materials consolidates the middle Qi and activates Qi circulation, thus ascending lucidity and descending turbidity. The combined use of pungent medicinal materials for dispersing and bitter medicinal materials for descending simultaneously raises warm and clear Qi. Wind-extinguishing medicinal materials facilitate the ascending of Qi and the opening of sweat pores. Accordingly, turbidity descends and lucidity ascends. The prescriptions incorporating these medication principles are in agreement with the therapeutic approach of following the normal flow of lucidity and turbidity. This paper clarifies the scientific connotation and micropathologic mechanism of ulcerative colitis from the perspective of mutual interference between lucidity and turbidity, providing new theories and prescriptions for the clinical diagnosis, treatment, and prevention of ulcerative colitis.

Objective To explore the efficacy and safety of converting the triple immunosuppressive regimen of tacrolimus (Tac) + mycophenolate mofetil (MMF) + prednisone (Pred) to a quadruple regimen of low-dose sirolimus (SRL) + low-dose Tac + MMF + Pred at 3 to 6 months after expanded criteria donor (ECD) kidney transplantation. Methods A single-center, retrospective, donor-matched controlled study included 22 ECD kidney transplant recipients from September 2021 to June 2024. Two recipients from the same donor kidneys were respectively assigned to the SRL group and the conventional triple regimen control group. The main outcome measures were the differences in serum creatinine (Scr), estimated glomerular filtration rate (eGFR), and adverse events before the regimen conversion and after conversion during the 1, 3, 6, and 12-month follow-up. Results There were no statistically significant differences in baseline characteristics between the two groups. In the SRL group, Scr decreased and eGFR increased starting from 3 months after conversion, and this was superior to the control group starting from 6 months(all P < 0.05). There were no statistically significant differences in the incidence of rejection reactions, pulmonary infections, hyperlipidemia and proteinuria between the two groups after conversion and during the 12-month follow-up (all P > 0.05). Conclusions For ECD kidney transplant recipients, converting the triple regimen to the SRL quadruple regimen at 3 to 6 months after transplantation may improve the function of the transplanted kidney without increasing the risk of adverse events.

ObjectiveThis paper aims to find the identified and validated clinical biomarker data building upon a clinical study of early-phase phase Ⅱ and investigate the correlation analysis of Huanglian Jiedu Wan on syndrome improvement and clinical biomarkers in the treatment of "excess heat-toxicity" based on a machine learning model. Additionally, the effective prediction of clinical biomarker values for the main symptoms of the "excess heat-toxicity" syndrome was assessed. MethodsA total of 229 patients meeting the inclusion criteria for "excess heat-toxicity" syndrome were randomly divided into the Huanglian Jiedu Wan group and the placebo group. Syndrome score transition matrices were constructed for the Huanglian Jiedu Wan group and the placebo group based on three main symptoms of "excess heat-toxicity" syndrome, such as oral ulcers, sore throat, and gum swelling and pain. Data from the patients with these three syndromes were also integrated for an overall analysis. The corresponding syndrome score transition matrices were further constructed to visualize symptom change trends of the patients in the two groups via heatmaps. Based on the identified and validated clinical biomarkers related to inflammation, oxidative stress, and energy metabolism in the early phase, Spearman correlation analysis was employed to analyze and evaluate the associations between clinical biomarkers and syndrome improvement. Key clinical biomarkers reflecting the effect of Huanglian Jiedu Wan were screened through the comparison of differences between groups. An extreme gradient boosting (XGBoost) algorithm was used to develop a prediction model for main symptom classification, with classification performance evaluated through 10-fold cross-validation. Feature importance analysis was applied to identify variables with the greatest contribution to the prediction result. ResultsThe syndrome transition matrix results indicated that the Huanglian Jiedu Wan group showed a superior effect to the placebo group in improving oral ulcers, sore throat, and overall symptoms, with significant effects observed especially in sore throat and overall symptom analyses (P<0.01). Spearman correlation analysis revealed that several clinical biomarkers positively correlated with "excess heat-toxicity" syndrome and its main symptom improvement, were also called "heat-related biomarkers", including succinic acid, α-ketoglutaric acid, glycine, lactic acid, adenosine monophosphate (AMP), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin-1β (IL-1β), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10), and so on. Conversely, clinical biomarkers negatively correlated with symptom severity, were also called "heat-clearing related biomarkers" after administration of Huanglian Jiedu Wan, including malic acid, fumaric acid, cis-aconitic acid, adrenocorticotropic hormone (ACTH), IL-1β, IL-4, IL-8, succinic acid, and citric acid. The XGBoost classification model using all 52 biomarkers as variables achieved an average test accuracy of 0.754 and an average F1 score of 0.777. Feature importance analysis identified the scores of glutamic acid in saliva and IL-6 were the highest in all the variables, with importance scores of 0.081 and 0.080, respectively. After screening out 14 key variables and optimizing the parameters, model performance improved to an average accuracy of 0.758 and an F1 score of 0.798. Feature importance analysis further determined that the glutamic acid in saliva and IL-6 showed obvious changes after screening the variables, confirming the good syndrome prediction ability of the model constructed by these key clinical biomarkers. ConclusionThis study systematically elucidates the correlation between syndrome improvement and clinical biomarkers of Huanglian Jiedu Wan in the treatment of "excess heat-toxicity" syndrome. An XGBoost classification model based on key clinical biomarkers is successfully established, achieving effective prediction of the symptoms related to the "excess heat-toxicity" syndrome such as oral ulcers and sore throat and providing a new insight for objective identification of traditional Chinese medicine syndromes.

Colorectal cancer, a leading malignant gastrointestinal tumor globally in terms of incidence and mortality, has seen a consistent annual rise in newly diagnosed cases. While conventional therapies like radiotherapy, chemotherapy, and surgery are available, problems such as lack of early diagnosis, poor prognosis, and drug resistance remain significant burdens for patients. Given the complex and diverse pathogenesis of colorectal cancer, there is an urgent clinical need for safe, effective, reliable, and multi-targeted therapeutic strategies. The Hippo signaling pathway, closely linked to mechanisms like tumorigenesis, cancer cell invasion, migration, and drug resistance, extensively participates in the occurrence and development of colorectal cancer, so targeting the signaling pathway for cancer prevention and treatment has become a crucial research direction in recent years. Traditional Chinese medicine (TCM) offers multi-faceted, multi-pathway, and multi-target advantages and becomes an important therapy for colorectal cancer by enhancing patients' immunity, improving the life quality, and prolonging survival. Studies show that the active components of TCM, including flavonoids, terpenoids, phenols, alkaloids, quinones, lignans, and saponins, as well as TCM compounds such as modified Sijunzi decoction, Jiedu Sangen decoction, Jianpi Jiedu compound, and Quyu Jiedu decoction, exhibit significant targeting effects on the Hippo signaling pathway. These TCMs can exert an anti-colorectal cancer effect through various mechanisms, such as inducing cancer cell autophagy and apoptosis, inhibiting epithelial-mesenchymal transition, reversing drug resistance of the tumor, and blocking the cancer cell cycle. This paper reviewed and analyzed Chinese and international research on the action mechanisms of TCM in regulating the Hippo signaling pathway for the prevention and treatment of colorectal cancer with a comprehensive overview presentation, aiming to provide new references and ideas for the clinical application of TCM and the development of new pharmacological agents in the prevention and treatment of colorectal cancer.

Dry eye disease(DED)is a common ocular surface disorder worldwide, primarily characterized by a loss of homeostasis of the tear film, and frequently associated with meibomian gland dysfunction(MGD), decreased tear film stability, ocular discomfort, and visual impairment. In recent years, factors such as the widespread use of digital devices,the aging population, and environmental changes have contributed to a significant increase in its global prevalence, making it a major public health concern. Red light therapy(RLT), also known as low-level laser therapy(LLLT)or photobiomodulation(PBM), is a non-invasive treatment that utilizes low-energy red or near-infrared light to irradiate tissues. It exerts photobiomodulatory effects to promote cellular repair and functional recovery. This therapy has demonstrated considerable potential in treating various ocular conditions. Its broader clinical application could improve therapeutic outcomes, alleviate patient discomfort and financial burden, and reduce the consumption of healthcare resources, thereby yielding significant socio-economic benefits. This paper systematically reviews the multifaceted mechanisms and application prospects of RLT in managing DED, including its anti-inflammatory effects, improvement of meibomian gland function, promotion of conjunctival goblet cell repair, and alleviation of visual fatigue, aiming to provide a theoretical foundation and practical reference for its clinical adoption.
