Animal experiments are essential tools in biomedical research, serving as a bridge between basic research and clinical trials. Systematic reviews and meta-analyses (SRs/MAs) of animal experiments are crucial methods for integrating evidence from animal experiment, which can facilitate the translation of findings into clinical research, reduce translational risks, and promote resource integration in basic research. With the continuous development of the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology, its application in SRs/MAs of animal experiments has gained increasing attention. This article first outlines the principles and specific applications of the GRADE methodology in SRs/MAs of animal experiments, including qualitative descriptive systematic reviews, meta-analyses, and network meta-analyses. It then deeply analyzes the misuse of the GRADE methodology in practice, including incorrect evidence grading, improper classification of evidence, misapplication in qualitative systematic reviews, inconsistencies between the documentation of the upgrading and downgrading process and results, and inappropriate use for making recommendations. Furthermore, this article comprehensively discusses the factors influencing the grading of evidence certainty in SRs/MAs of animal experiments, including the impact of bias risk, indirectness, inconsistency, imprecision, and publication bias on evidence downgrading, as well as the role of large effect sizes and cross-species consistency in evidence upgrading. Finally, in response to the issues discussed, improvement strategies are proposed, including further research and optimization of the GRADE methodology for SRs/MAs of animal experiments, the development of reporting guidelines tailored to the characteristics of SRs/MAs in animal experiment research, and enhanced professional training for researchers in the GRADE methodology. This article aims to improve the quality of evidence in SRs/MAs of animal experiments, strengthen their reliability in clinical decision-making, and promote the more efficient translation of findings from animal experiment research into clinical practice.

Yuejuwan is a classic formula widely used by doctors to relieve liver and depression, with precise clinical efficacy in traditional Chinese medicine (TCM). The authors used bibliometric methods to collect and collate 495 ancient data related to Yuejuwan, and 105 valid data were screened out, involving 68 ancient Chinese medical books. After systematic verification of the origin of the formula of Yuejuwan, the main treatment symptoms, the principle of the formula, the composition of the drug, the dosage, the preparation method, the decoction method, and other information, the results showed that Yuejuwan originated from the Danxi Xinfa (《丹溪心法》) of the Yuan Dynasty by ZHU Zhenheng, and it is composed of five medicines, namely Atractylodis Rhizoma, Cyperi Rhizom, Chuanxiong Rhizoma, Massa Medicata Fermentata, and Gardeniae Fructus. In terms of drug base, Atractylodis Rhizoma, Cyperi Rhizom, Chuanxiong Rhizoma, and Gardeniae Fructus are in line with the records in the 2020 edition of Chinese Pharmacopoeia, and Massa Medicata Fermentata is used. The preparation method is as follows: Massa Medicata Fermentata and Gardeniae Fructus are fried, and Cyperi Rhizoma is roasted in vinegar. Chuanxiong Rhizoma is used in the raw form, and Atractylodis Rhizoma is prepared with rice swill. The formula can regulate Qi and relieve depression and broaden the middle and remove fullness. It is clinically used for the treatment of six types of depression syndromes, chest and diaphragm plumpness, abdominal distension and leg acid, acid swallowing and vomiting, eating and drinking disharmony, toothache, mouth and tongue sores, and other diseases. The most used dosage of the formula in the ancient records through the ages is converted into the modern dosage, namely 3.05 g Atractylodis Rhizoma, 3.05 g Cyperi Rhizoma, 3.05 g Chuanxiong Rhizoma, 3.05 g Massa Medicata Fermentata, and 3.05 g Gardeniae Fructus, and the daily dosage is 15.25 g. The converted dosage is similar to that recorded in the 2020 edition of the Chinese Pharmacopoeia. The formula is in pill form, and medicine should be taken with lukewarm boiled water after the meal. Through the excavation of the ancient literature related to Yuejuwan, the key information of the formula is identified, with a view to providing a more accurate reference for the clinical application of Yuejuwan and subsequent in-depth investigation.

5.Research Advances in Targeting the YAP/TAZ Signaling Pathway to Improve Cancer Immunotherapy.
Chinese Journal of Lung Cancer 2025;28(3):221-229
Despite the groundbreaking advances in cancer immunotherapy achieved by immune checkpoint inhibitors (ICIs), their efficacy remains limited by the immunosuppressive tumor microenvironment (TME). Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ), key effectors of the Hippo signaling pathway, play pivotal roles in tumor immune evasion. They directly regulate the expression of immune checkpoints, mediate the formation of an immunosuppressive microenvironment, inhibit T cell function, and interact with other signaling pathways to promote immune escape. Diverse strategies targeting YAP/TAZ have been developed, including direct inhibition, modulation of upstream regulators, and suppression of downstream target genes. Preclinical studies have demonstrated that combining YAP/TAZ inhibition with ICIs significantly enhances therapeutic efficacy across various tumor models. This review summarizes recent advances in understanding the role of YAP/TAZ in immune evasion within the TME and explores the potential of targeting this pathway to improve immunotherapy outcomes. Furthermore, it discusses the translational value of combination therapies based on YAP/TAZ inhibition, providing a theoretical framework and practical guidance for the development of innovative immunotherapeutic strategies and precision medicine approaches.

Gelsemium elegans (G. elegans) is an extremely poisonous plant that is widely distributed in southern China and southeastern Asia. G. elegans poisoning events occur frequently in southern China, and are therefore an urgent public health problem requiring multidisciplinary action. However, the toxic components and toxicological mechanisms remain unclear. Here, we describe a systematic investigation on the toxic components of G. elegans, resulting in the isolation and identification of 120 alkaloids. Based on acute toxicity screening, the structure-toxicity relationship of Gelsemium alkaloids was proposed for the first time. Moreover, gelsedine- and humantenine-type alkaloids were detected in the clinical blood sample, and were confirmed to be causative in the poisoning. The most toxic compound, gelsenicine (1), had selective inhibitory effects toward ventral respiratory group (VRG) neurons in the medulla, which is the main brain region controlling respiration in the central nervous system. Gelsenicine (1) strongly inhibited the firing of action potentials in VRG neurons through its ability to stimulate GABAA receptors, the main receptors involved in inhibitory neurotransmission. Application of GABAA receptor antagonists successively reversed action potential firing in gelsenicine (1)-treated VRG neurons. Importantly, the GABAA receptor antagonists securinine and flumazenil significantly increased the survival of poisoned animals. Our findings provide insight into the components and mechanisms of G. elegans toxicity, and should assist the development of effective emergency treatments for G. elegans poisoning.

Adenomyosis is a common gynecological disease characterized by the invasion of endometrial glands and stroma into the myometrium of uterus, the pathological mechanism of which remains unclear yet. Disturbed lipid metabolism extensively affects abnormal cell proliferation and invasion in various diseases. However, the lipidome signature of human myometrium, which could be crucial in the development of adenomyosis, remains unknown. In this study, we generated the first lipidome profiling of human myometrium using a high-coverage and quantitative lipidomics approach based on ultra-performance liquid chromatography (UPLC) coupled with triple quadrupole (QqQ)-mass spectrometry (MS). A total of 317 lipid species were successfully quantified in the myometrial tissues from women with (n = 38) or without (n = 65) adenomyosis who underwent hysterectomy at Peking Union Medical College Hospital (Bejing, China). Up to 83 lipid species showed significant alternations in content between the two groups. These lipid aberrations involved multiple metabolic pathways, and emphasized inflammation, cell migration, and immune dysregulation upon adenomyosis. Moreover, receiver operating characteristic (ROC) curve analysis found that the combination of five lipid species could accurately distinguished the myometrial samples from women with and without adenomyosis with an area under the curve (AUC) of 0.906. Desorption electrospray ionization MS imaging (MSI) further underscored the heterogeneous distributions of these lipid markers in the adenomyosis lesion and adjacent myometrial tissue. Collectively, these results extremely improved our understanding on the molecular basis of adenomyosis, and could shed light on developing potential biomarkers and new therapeutic directions for adenomyosis.
8.Research Advances in the Association Between Inflammation and Amyloid Toxicity in Alzheimer’s Disease
Journal of Sun Yat-sen University(Medical Sciences) 2025;46(6):973-984
Amyloid-β peptide (Aβ) is considered a major cause of Alzheimer's disease (AD). However, current researches emphasize that Aβ can activate microglia and astrocytes, which causes neuroinflammation. Neuroinflammation plays a crucial role in the neuronal mortality process, and can be considered the underlying cause of AD. In addition, vascular damage was proposed to play an important role in the pathogenesis of AD more than two decades ago, but few researchers have focused on the positive role of cerebrovascular damage in AD. In recent years, a growing body of evidence has supported that brain microvascular injury causes the occurrence of AD. Moreover, recent research indicated that inflammation caused by brain microvascular injury is also a significant risk factor for the development of AD. In damaged microvessels, C-reactive protein (CRP) is a non-specific inflammatory marker, which can activate the complement and enhance phagocytosis of immune cells, and help to eliminate pathogenic microorganisms from the body. The plenty of evidence indicated that CRP penetrated brain tissue and participated in neuroinflammation during brain microvascular injury, thereby influencing the pathogenesis of AD. Therefore, the negative effects of CRP and Aβ on the pathogenesis of AD are equally important. At present, few researchers have established a link between the effects of CRP and Aβ on AD and conducted in-depth analysis. This article firstly and deeply analyzed and summarized the significant function and connection of Aβ and CRP in AD, which provided support for the theory that neuronal cerebrovascular injury is the cause of AD.

Objective To investigate the effect and potential molecular mechanism of PTGS2 on the prognosis of colon cancer patients.Methods The transcriptomic and proteomic data of pan-cancer were collected from TCGA,HPA,UALCAN and other databases,and the expression pattern and prognostic value of PTGS2 were analyzed by combining the clinical data such as staging,histology,survival time and so on.Based on GSEA,the biological functions which were significantly activated in patients with high expression of PTGS2 were iden-tified and the colon cancer cell line SW480 was used as an example for in vitro validation.PTGS2 over-expressing cell strains were constructed,and the effect on cell proliferation was determined by CCK8 method.Different concen-trations of H2O2 were used to form gradient oxidative stress,and the changes in cell antioxidant capacity were detected.The regulatory mechanism was preliminarily verified by Western blot.Results The transcription and expression of PTGS2 were found to be significantly up-regulated in colon cancer patients(P<0.05),and the increased expression of PTGS2 was associated with an increased mortality risk(P<0.05).Data analysis and in vitro experiments showed that over-expression of PTGS2 may promote the proliferation of colon cancer cells by activating the mTOR pathway.The antioxidant effect of cells was regulated by up-regulating oxidative stress regulatory proteins SOD2 and NRF2.Conclusions PTGS2 is a potential risk factor for colon cancer and its over-expression promotes cell proliferation,enhances cell antioxidant effect and is associated with poor progno-sis of colon cancer patients.
