The Dunhuang manuscript Fuxing Jue takes the "Tangye Jingfa Tu" as the core of its theory on prescription and compatibility. Its medication principles mainly include the "five elements principle of tonifying and purging" and the "five elements principle of elimination and transformation". Based on the differentiation of deficiency and excess in the five Zang organs， it flexibly applies medicinal properties， usage， and flavor transformation for tonifying and purging， forming its unique method of medication and compatibility. In Taiyin disease， "fullness syndrome" often occurs together with "diarrhea"， and these two conditions also serve as the primary indications for the middle-regulating formulas. Among them， Lizhong Wan （Tang） mainly address Taiyin deficiency. The three Xiexin Tang （Banxia Xiexin Tang， Gancao Xiexin Tang， Shengjiang Xiexin Tang） address Taiyin deficiency accompanied by pathogenic excess. The Sini Tangand Tongmai Sini Tang primarily treat dysfunction of the liver， spleen， and kidney with impaired opening and closing of Taiyin， manifesting as diarrhea. The medicinal flavors of middle-regulating formulas are pungent， sweet， and bitter， acting directly on the spleen of Taiyin. The pungent flavor induces purging of the spleen， sweet flavor tonifies the spleen， and bitter flavor eliminates lumps. When the constituent medicinal units of middle-regulating formulas are unified， the ratio of pungent to sweet flavors reflects the tonic and purgative strength of the formula. In addition， the two decoction methods， "short-term decoction to extract Qi" and "long-term decoction to extract flavor"， also influence the formula's tonifying and purgative effects. Based on the composition of flavors and special decoction methods， this article discusses the differences in the use of middle-regulating formulas for treating "“fullness syndrome" versus "diarrhea". Dysfunction of the spleen can give rise to various diseases. Therefore， middle-regulating formulas are not limited to treating "deficiency， cold， and dampness" syndromes. Later generations of physicians further modified Lizhong Tang to treat "excess， heat， and dryness" syndromes， laying a solid foundation for more flexible and effective clinical application of middle-regulating formulas.

Based on the theory of "disease of both blood and water" in Essentials from the Golden Cabinet （《金匮要略》）， and in combination with the dynamic syndrome evolution of heart failure with preserved ejection fraction （HFpEF）， this paper systematically clarifies the pathomechanism of HFpEF， characterized by yang deficiency as the root， blood stasis as the pivotal factor and water retention as the manifestation. Accordingly， the therapeutic principles have been proposed， which are warming yang and banking up original qi to consolidate the root， activating blood and unblocking collaterals to smooth the mechanism， and promoting urination and regulating pivot to remove the branch. On this basis， a compound formula structure of "one monarch， one minister and one assistant" is established， forming an integrated intervention strategy that synergistically combines the three methods of warming yang， activating blood， and promoting urination through combined classical formulas. Zhenwu Decoction （真武汤）， which warms yang and dissolves rheum， is used to consolidate the root and directly target the source of yang deficiency， serving as the monarch； Guizhi Fuling Pills （桂枝茯苓丸）， which activates blood， promotes urination and unblocks the pivot， assists in interrupting the binding of blood stasis and water retention， serving as the minister； Tingli Dazao Xiefei Decoction （葶苈大枣泻肺汤）， which regulates qi， disperses retained fluids， and eliminates the manifestation， alleviates acute water-retention symptoms， serving as the assistant. This compound formula is warming without being drying， diuretic without being drastic， and dispels stasis without consuming blood， thereby achieving the therapeutic effects of warming yang， activating blood， and promoting urination.

Animal experimentation constitutes a critical link between basic research and clinical application, making its research quality and translational efficiency paramount. Although considerable progress has been made in standardizing operational procedures and ethical guidelines, the standardization of outcome evaluation systems has significantly lagged, creating a key bottleneck that constrains the quality of biomedical research and evidence synthesis. This deficiency is manifested by pronounced heterogeneity in outcome selection across similar studies, incomplete methodological reporting, and disparate criteria for result interpretation, which severely impairs the comparability of findings and the evidence integration. To cope with this challenge, this paper systematically introduces a mature methodological tool from clinical research–the core outcome set (COS)–and explores its construction strategies and application potential in the field of animal experimentation. Given the extensive diversity of animal experiments, a pragmatic strategy of "focusing on key areas, implementing phased pilots, and promoting gradual expansion" should be adopted. This approach prioritizes the development of domain-specific COS for disease areas characterized by high research volume, urgent translational needs, and well-established animal models. A multi-source integration pathway for COS development is detailed, comprising systematic literature searches, methodological appraisals, and expert consensus, with the feasibility of leveraging artificial intelligence (AI) to enhance efficiency also being examined. The development and promotion of such COS are not intended to restrict scientific exploration; rather, they aim to establish a new, tiered evaluation paradigm consisting of "core outcomes" (mandatory), "recommended outcomes" (encouraged), and "exploratory outcomes" (optional). This framework is expected not only to enhance research quality through standardization and to adhere to the "3R" principles but also to accelerate the accumulation of high-quality evidence. This, in turn, provides a solid foundation for higher-level evidence synthesis, ultimately facilitating the effective translation of basic research findings into clinical practice and providing an essential methodological framework for scientific advancement in relevant disciplines.

Complexity science and traditional Chinese medicine （TCM） share a profound intrinsic compatibility. To address the limitations of reductionist approaches in guiding the dynamically holistic theory and practice of TCM， this paper develops​ a novel research pathway under the guidance of complexity science， using the open complex giant systems （OCGS） theory as its practical framework， upholding the fundamental principles of TCM and breaking new ground of artificial intelligence （AI）. The core tasks of this pathway involve the objectification and structured diagnosis-treatment systems， and the construction of a complex， large-scale TCM model. The paper further delineates the data architecture design and reinforcement learning training pathway. Acknowledging the differences in information processing between the human brain and computers， it proposes a training strategy that minimizes manual labeling of "syndromes" and instead focuses on the training paradigm of "herb-human interaction → syndrome manifestation → dosage adjustment". Under the guidance of complexity science theory， TCM is poised for deep integration with AI technology， driving technological innovation powered by data and computational capabilities.

Objective To investigate the effect of butorphanol on lipopolysaccharide-induced chondrocyte injury by regulating the stromal cell-derived factor-1α(SDF-1α)/C-X-C chemokine receptor 4(CXCR4)pathway.Methods Human C28/12 chondrocytes were cultured in vitro and assigned to the following groups:control(normal culture),model(100 μmol/L lipopolysaccharide),model+low-dose butorphanol(100 μmol/L lipopolysaccharide+1μmol/L butorphanol),model+medium-dose butorphanol(100 μmol/L lipopolysaccharide+2 μmol/L butorphanol),model+high-dose butorphanol(100 μmol/L lipopolysaccharide+4 μmol/L butorphanol),and model+high-dose butorphanol+NUCC-390(100 μmol/L lipopolysaccharide+4 μmol/L butorphanol+500 nmol/L CXCR4 agonist NUCC-390).Cell viability,interleukin(IL)-6 and tumor necrosis factor-α(TNF-α)levels,apoptosis,and SDF-1α/CXCR4 pathway-related proteins were evaluated by MTT assay,enzyme-linked immunosorbent assay,flow cytometry,and Western blot,respectively.Results Chondrocyte survival rate and Bcl-2 protein expression were decreased while TNF-α,IL-6,apoptosis rate,Bax,Cleaved caspase-3,SDF-1α,and CXCR4 proteins were increased in the model group compared with the control group(P＜0.05).The above indicators were improved in the model+low-,medium-,and high-dose butorphanol groups compared with the model group,while the result for the model+high-dose butorphanol+NUCC-390 group were opposite to those of the model+high-dose butorphanol group.Conclusions Butorphanol may improve lipopolysaccharide-induced chondrocyte injury induced by inhibiting the SDF-1α/CXCR4 signaling pathway.

There is a close relationship between cardiovascular disease and psychological disease in pathogenesis,treatment and prognosis,but the specific pathological mechanism is not clear.This article explored the understanding of heart failure with anxiety and depression in TCM based on the theory of"deficient qi stagnation",and discussed the pathological mechanism and treatment methods of micro-inflammatory state in heart failure with anxiety and depression in combination with relevant research in both TCM and Western medicine.It is believed that"deficient qi"is the internal factor for the onset of heart failure with anxiety and depression,and"stagnation"is an important pathological condition for the onset.Treatment can be carried out by tonifying qi and blood,nourishing yin and warming yang to replenish"deficient qi",and regulating qi,resolving phlegm,promoting blood circulation,removing blood stasis and promoting diuresis to unblock"stagnation",which can provide theoretical reference for related research and integrated treatment of traditional Chinese and Western medicine on this disease.

Swine enteric coronaviruses(SeCoV),such as porcine epidemic diarrhea virus(PEDV),transmissible gastroenteritis virus(TGEV),and porcine delta coronavirus(PDCoV),cause severe diarrhea in piglets,resulting in substantial losses in pig farming.In this study we establish a triple fluorescence reverse transcription-quantitative PCR(RT-qPCR)method for the simultaneous de-tection of PEDV,TGEV,and PDCoV.The specific primers and probes for each target virus were designed based on conserved sequences from the PEDV M gene,the TGEV ORF 1b gene,and the PDCoV ORF 1b gene respectively.Following the optimization of parameters and conditions,a triple RT-qPCR method was successfully established to simultaneously detect PEDV,TGEV,and PD-CoV.The developed assay exhibits strong specificity for these three pathogens without any cross-reaction with other common porcine viruses like CSFV,PCV2,PoRVA,PRV,and PRRSV.The de-tection limit of linear templates for pTOPO-PEDV 128,pTOPO-TGEV 116,and pTOPO-PDCoV 125 recombinant plasmids were 16.835,17.610 and 17.020 copies/μL,respectively.The intra group and inter group coefficients of variation were less than 5％,with no significant differences observed(P＞0.05).Moreover,the detection consistency rate of the developed RT-qPCR was compared with standard method and showed 100％agreement.Out of 35 small intestine tissue samples,17 tested positive for PEDV,resulting in a positive rate of 48.57％(17/35).The tests for TGEV and PDCoV yielded negative results,and no mixed infections were detected.Based on the above results,the tri-ple RT-qPCR method established is specific,sensitive,stable,and rapid,and can be used for clinical detection and differential diagnosis of PEDV,TGEV,and PDCoV simultaneously,providing a method for the detection and epidemiological investigation of porcine diarrhea coronaviruses.

To investigate the role of the DPP4-nestin axis in liver fibrosis induced by alveolar cyst infection,a murine model was established using C57BL/6 mice via hepatic portal vein injection.Liver histopathological changes were assessed using HE staining,while immunohistochemistry and immunofluorescence were employed to evaluate the expression levels of nestin and DPP4 in infected mouse livers.In vitro,J S1 cell line was stimulated with recombinant DPP4 protein to es-tablish a cellular model,and qPCR,Western blot,and shRNA lentivirus interference techniques were utilized to examine the involvement of the DPP4-nestin axis in hepatic stellate cell activation.The findings demonstrated that compared to the Sham group,liver tissue structure disruption and collagen deposition were evident along with significantly increased expressions of nestin and DPP4(P＜0.050 0),which colocalized with nesin and α-SMA.Furthermore,stimulation with recombi-nant DPP4 protein significantly enhanced JS1 cell activation(P＜0.050 0)as well as upregulated nestin expression(P＜0.050 0)when compared to control group cells.Notably,shRNA lentivirus-mediated inhibition of nestin expression effectively suppressed the activating effects exerted by re-combinant DPP4 protein on JS1 cells(P＜0.050 0).Collectively,these results highlight the crucial regulatory role played by the DPP4-nestin axis in hepatic stellate cell activation triggered by alveo-lar infection;thus,targeting this axis may represent a novel therapeutic strategy for treating alveo-lar infection-induced liver fibrosis.
