Toxoplasmosis, a zoonotic disease caused by the obligate intracellular parasite Toxoplasma gondii, is widely prevalent across the world. The life cycle of T. gondii involves definitive hosts (cats and felines), intermediate hosts (humans, livestock, and wild animals), and the environment (such as soil and water). The One Health concept brings together the health of humans, animals, and the environment, with aims to pursue the optimal health outcomes through coordinated management. Management of toxoplasmosis from a One Health perspective may provide key insights into formulation of interventions for toxoplasmosis control. This article reviews the complex biological characteristics and life cycle of T. gondii, as well as the importance of felines as definitive hosts in the transmission of toxoplasmosis, analyzes the epidemiology, ecological impact and economic burden of toxoplasmosis, and discusses the bottlenecks in diagnostic and monitoring systems, environmental management technologies, and One Health interdisciplinary collaboration. In addition, toxoplasmosis control strategies are proposed based on the One Health concept, covering public health interventions, management of animal sources, multi-sector collaboration, and development of novel vaccines. These strategies provide insights into interruption of toxoplasmosis transmission and maintenance of the global public health security.

ObjectiveTo investigate the effect of Qingrun prescription(QRP)-containing serum on improving insulin resistance in HepG2 cells and its potential mechanisms. MethodsAn insulin resistance model was established in HepG2 cells with 1×10-6 mol·L-1 insulin. Branched-chain α-keto acid dehydrogenase (BCKDH) gene silencing was achieved using siRNA, and the cells were divided into 8 groups: normal group, model group (1×10-6 mol·L-1 insulin), metformin group (1 mmol·L-1 metformin), high-, medium-, and low-dose QRP groups (20%, 10%, and 5% QRP-containing serum, respectively), QRP + siRNA-silenced BCKDH (si-BCKDH) group (10% QRP-containing serum + si-BCKDH), and QRP + si-NC group (10% QRP-containing serum + si-NC). Glucose levels in the supernatant were measured with a glucose assay kit, while glycogen content was assessed using a glycogen assay kit. Levels of branched-chain amino acids (BCAAs) and branched-chain keto acids (BCKAs) were determined using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). mRNA transcription and protein expression levels of BCKDH, dishevelled, Egl-10, and pleckstrin (DEP) domain-containing mammalian target of rapamycin (mTOR)-interacting protein (DEPTOR), mTOR, and ribosomal protein S6 kinase 1 (S6K1) were detected using real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot. ResultsCompared to the normal group, the model group exhibited significantly decreased glucose consumption and glycogen content, increased levels of BCAAs and BCKAs, downregulated expression of BCKDH and DEPTOR, and upregulated mTOR and S6K1 expression (P<0.01). In comparison to the model group, QRP treatment at all doses significantly enhanced glucose consumption and glycogen content while reducing BCAAs and BCKAs levels (P<0.01). The high- and medium-dose QRP groups demonstrated significant upregulation of BCKDH mRNA transcription and protein expression, as well as DEPTOR mRNA transcription. Moreover, the DEPTOR protein expression level was significantly increased in high-, medium-, and low-dose QRP groups, while mTOR and S6K1 mRNA and protein expression levels were markedly downregulated (P<0.05, P<0.01). Compared to the QRP + si-NC group, the QRP + si-BCKDH group exhibited increased BCAAs and BCKAs levels, significantly decreased BCKDH mRNA transcription and protein expression, downregulated DEPTOR mRNA and protein expression, and upregulated mTOR and S6K1 mRNA and protein expression (P<0.05, P<0.01). ConclusionQRP may improve insulin resistance by reprogramming BCAAs metabolism. This effect involves upregulating BCKDH, reducing BCAAs and BCKAs levels, and suppressing the mTOR pathway activation.

This study aims to investigate the mechanism of Qingrun Decoction in alleviating hepatic insulin resistance in type 2 diabetes mellitus(T2DM) rats through the reprogramming of amino acid metabolism. A T2DM rat model was established by inducing insulin resistance through a high-fat diet combined with intraperitoneal injection of streptozotocin. The model rats were randomly divided into five groups: model group, high-, medium-, and low-dose Qingrun Decoction groups, and metformin group. A normal control group was also established. The rats in the normal and model groups received 10 mL·kg~(-1) distilled water daily by gavage. The metformin group received 150 mg·kg~(-1) metformin suspension by gavage, and the Qingrun Decoction groups received 11.2, 5.6, and 2.8 g·kg~(-1) Qingrun Decoction by gavage for 8 weeks. Blood lipid levels were measured in different groups of rats. Pathological damage in rat liver tissue was assessed by hematoxylin-eosin(HE) staining and oil red O staining. Transcriptome sequencing and untargeted metabolomics were performed on rat liver and serum samples, integrated with bioinformatics analyses. Key metabolites(branched-chain amino acids, BCAAs), amino acid transporters, amino acid metabolites, critical enzymes for amino acid metabolism, resistin, adiponectin(ADPN), and mammalian target of rapamycin(mTOR) pathway-related molecules were quantified using quantitative real-time polymerase chain reaction(qRT-PCR), Western blot, and enzyme-linked immunosorbent assay(ELISA). The results showed that compared with the normal group, the model group had significantly increased serum levels of total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), and resistin and significantly decreased ADPN levels. Hepatocytes in the model group exhibited loose arrangement, significant lipid accumulation, fatty degeneration, and pronounced inflammatory cell infiltration. In liver tissue, the mRNA transcriptional levels of solute carrier family 7 member 2(Slc7a2), solute carrier family 38 member 2(Slc38a2), solute carrier family 38 member 4(Slc38a4), and arginase(ARG) were significantly downregulated, while the mRNA transcriptional levels of solute carrier family 1 member 4(Slc1a4), solute carrier family 16 member 1(Slc16a1), and methionine adenosyltransferase(MAT) were upregulated. Furthermore, the mRNA transcription and protein expression levels of branched-chain α-keto acid dehydrogenase E1α(BCKDHA) and DEP domain-containing mTOR-interacting protein(DEPTOR) were downregulated, while mRNA transcription and protein expression levels of mTOR, as well as ribosomal protein S6 kinase 1(S6K1), were upregulated. The levels of BCAAs and S-adenosyl-L-methionine(SAM) were elevated. The serum level of 6-hydroxymelatonin was significantly reduced, while imidazole-4-one-5-propionic acid and N-(5-phospho-D-ribosyl)anthranilic acid levels were significantly increased. Compared with the model group, Qingrun Decoction significantly reduced blood lipid and resistin levels while increasing ADPN levels. Hepatocytes had improved morphology with reduced inflammatory cells, and fatty degeneration and lipid deposition were alleviated. Differentially expressed genes and differential metabolites were mainly enriched in amino acid metabolic pathways. The expression levels of Slc7a2, Slc38a2, Slc38a4, and ARG in the liver tissue were significantly upregulated, while Slc1a4, Slc16a1, and MAT expression levels were significantly downregulated. BCKDHA and DEPTOR expression levels were upregulated, while mTOR and S6K1 expression levels were downregulated. Additionally, the levels of BCAAs and SAM were significantly decreased. The serum level of 6-hydroxymelatonin was increased, while those of imidazole-4-one-5-propionic acid and N-(5-phospho-D-ribosyl)anthranilic acid were decreased. In summary, Qingrun Decoction may improve amino acid metabolism reprogramming, inhibit mTOR pathway activation, alleviate insulin resistance in the liver, and mitigate pathological damage of liver tissue in T2DM rats by downregulating hepatic BCAAs and SAM and regulating key enzymes involved in amino acid metabolism, such as BCKDHA, ARG, and MAT, as well as amino acid metabolites and transporters.
