Cancer is one of the deadliest diseases affecting the health of human beings. With limited therapeutic options available, complementary and alternative medicine has been widely adopted in cancer management and is increasingly becoming accepted by both patients and healthcare workers alike. Chinese medicine characterized by its unique diagnostic and treatment system is the most widely applied complementary and alternative medicine. It emphasizes symptoms and ZHEng(syndrome)-based treatment combined with contemporary disease diagnosis and further stratifies patients into individualized medicine subgroups. As a representative cancer with the highest degree of malignancy, pancreatic cancer is traditionally classified into the "amassment and accumulation". Emerging perspectives define the core pathogenesis of pancreatic cancer as "dampness-heat" and the respective treatment "clearing heat and resolving dampness" has been demonstrated to prolong survival in pancreatic cancer patients, as has been observed in many other cancers. This clinical advantage encourages an exploration of the essence of dampness-heat ZHEng(DHZ) in cancer and investigation into underlying mechanisms of action of herbal formulations against dampness-heat. However, at present, there is a lack of understanding of the molecular characteristics of DHZ in cancer and no standardized and widely accepted animal model to study this core syndrome in vivo. The shortage of animal models limits the ability to uncover the antitumor mechanisms of herbal medicines and to assess the safety profile of the natural products derived from them. This review summarizes the current research on DHZ in cancer in terms of the clinical aspects, molecular landscape, and animal models. This study aims to provide comprehensive insight that can be used for the establishment of a future standardized ZHEng-based cancer animal model.

The emergence of exotic quantum phenomena in frustrated magnets is rapidly driving the development of quantum many-body physics,raising fundamental questions on the nature of quantum phase *** we unveil the behaviour of emergent symmetry involving two extraordinarily representative phenomena,i.e.,the deconfined quantum critical point(DQCP)and the quantum spin liquid(QSL)*** large-scale tensor network simulations,we study a spatially anisotropic spin-1/2 square-lattice frustrated antiferromagnetic(AFm)model,namely the J1x-J1y-J2 model,which contains anisotropic nearestneighbor couplings J1x,J1y and the next nearest neighbor coupling *** small J1y/J1x,by tuning J2,a direct continuous transition between the AFm and valence bond solid phase is *** growing J1y/J1x,a gapless QSL phase gradually emerges between the AFm and VBS *** observe an emergent O(4)symmetry along the AFm–VBS transition line,which is consistent with the prediction of DQCP *** surprisingly,we find that such an emergent O(4)symmetry holds for the whole QSL–VBS transition line as *** findings reveal the intrinsic relationship between the QSL and DQCP from categorical symmetry point of view,and strongly constrain the quantum field theory description of the QSL *** phase diagram and critical exponents presented in this paper are of direct relevance to future experiments on frustrated magnets and cold atom systems.

This study was to evaluate the effect of supplementing the diet of broilers with Neolamarckia cadamba leaf extract(NCLE) on meat quality by evaluating antioxidant parameters and the expression of genes in the p38 mitogen-activated protein kinase/nuclear factor-erythroid 2-related factor 2/antioxidant responsive element(p38 mAPK/Nrf2/ARE) signaling pathway, coupled with LC-mS-based metabolomic analysis. A total of 480 one-day-old male broilers were randomly allocated to four treatment groups—a control(CON)group, which was fed a basal diet, and three NCLE treatment groups, which were fed the basal diet supplemented with 100, 200, or 400 mg/kg NCLE(N1, N2, and N3 groups, respectively) for 42 d. Compared with the CON group, meat quality was improved in the N2 and N3 groups, as evidenced by the higher p H45min(P muscle(Bm) and lower drip loss at48 h(P muscle(Lm). moreover, Bm antioxidant capacity was significantly enhanced in the N3group, characterized by an increase in the total antioxidant capacity(T-AOC), the concentrations of glutathione peroxidase(GSH-Px) and catalase(CAT), and the relative mRNA expression of p38 mAPK,extracellular-signal regulated kinase 1/2(ERK1/2), c-Jun N-terminal kinase(JNK), Nrf2, CAT, and GSH-Px(P milarly, Lm in the N3 group displayed higher T-AOC, increased GSH-Px and CAT concentrations,reduced malonaldehyde contents(P mRNA levels of JNK, Nrf2,heme oxygenase, CAT, and superoxide dismutase(SOD)(P metabolomics analysis revealed that Darabinono-1,4-lactone and lyso-PAF C-16-d4 were negatively correlated with shear force and cooking loss(P m of the N3 group.
