In recent years，the incidence and prevalence of non-tuberculous mycobacterial（NTM）infections have been on the rise，posing a serious threat to public health and presenting significant challenges for disease management. Currently，the treatment outcomes for NTM disease are poor，one of the main reasons being the high resistance of NTM pathogens to various anti-mycobacterial drugs. Novel therapeutic strategies targeting the host rather than the NTM pathogens themselves may help improve cure rates and reduce mortality. This article summarizes the latest research findings on host factors related to the incidence of NTM disease，including age，pulmonary diseases，immune function，genetic factors and lifestyle，which aids in the early identification of high-risk populations and provides a theoretical basis for developing targeted prevention and treatment strategies and optimizing treatment plans.

Objective:To generate a chronic lymphocytic leukemia (CLL) mouse model with intact immune competence and short latency by adoptively transferring (AT) splenocytes from immunoglobulin heavy-chain enhancer-driven T-cell leukemia/lymphoma 1 (Eμ-TCL1) transgenic donors into wild-type (WT) recipients.Methods:Specific pathogen-free C57BL/6J WT mice and H11-Eμ-VH-TCL1-β-globin-PolyA knock-in mice were utilized. The H11-Eμ-VH-TCL1-β-globin-PolyA knock-in mice were generated using CRISPR/Cas9 technology, and their genotypes were confirmed by PCR. Experimental animals were randomly divided into an adoptive transfer (AT) group and a WT control group ( n=10 per group). Mice in the AT group received an intraperitoneal injection of splenocytes from H11-Eμ-VH-TCL1-β-globin-PolyA knock-in mice. The weight and general condition of the mice were monitored. Mice were euthanized by cervical dislocation at 9 weeks post-transplantation. The CLL model was validated using key indicators, including pathological manifestations, changes in peripheral blood leukocyte counts, and immunophenotype. Results:AT group mice exhibited significantly increased spleen weight [ (0.92±0.16) g vs (0.06±0.01) g in WT group, P<0.05] and liver weight [ (2.11±0.56) g vs (1.42±0.13) g in WT group, P=0.006], indicative of marked splenomegaly and hepatomegaly. The peripheral blood leukocyte count was significantly higher in the AT group [ (124.33±8.74) ×10 9/L] compared to the WT group [ (5.55±1.67) ×10 9/L] ( P=0.002). Similarly, the percentage of peripheral blood B lymphocytes was markedly increased in the AT group versus the WT group [ (69.13±6.88) % vs (39.78±5.94) %, P<0.05]. Histopathological examination revealed CLL manifestations in the spleen, lymph nodes, and bone marrow of AT group mice, with significant lymphocytic infiltration observed in the liver, lung, and kidney tissues. Flow cytometry analysis showed that the percentages of CD19 +CD5 + B lymphocytes among total lymphocytes in peripheral blood, bone marrow, and spleen of the AT group were (61.37±9.92) %, (28.61± 7.08) %, and (86.03±5.78) %, respectively. These were significantly higher (all P<0.05) than in the WT group [ (4.51±1.32) %, (5.58±1.46) %, and (14.33±3.20) %]. Furthermore, these CLL-like cells in the AT group were positive for CD43 and CD200, but showed lower expression of CD20, CD22, and CD79b compared to WT B cells. Conclusion:Adoptive transfer of splenocytes from Eμ-TCL1 transgenic mice successfully established a CLL mouse model with a relatively short latency period. This model represents a valuable preclinical tool for investigating CLL and related pathologies.

The paper reviews the evolution of the theory related to meridians and zangfu organs during the Warring States, Qin and Han dynasties, so as to reveal the rules and value of its development. By analyzing historical documents, especially Zubi Shiyimai Jiujing (Moxibustion Classics of Eleven Meridians of Legs and Arms), Yinyang Shiyimai Jiujing (Moxibustion Classic on Eleven Yin and Yang Meridians), Laoguanshan bamboo medical slips of Han Dynasty and lacquer figure of meridian points, the evolutionary stages, i.e. the germination, development, and maturity of meridian-zangfu theory, are explored. In the time of the Warring States, Qin and Han dynasties, the meridian-zangfu related theory was developed from the germination to the maturity. In the classics of the early time, Zubi Shiyimai Jiujing and Yinyang Shiyimai Jiujing demonstrated the preliminary relationship between meridians and zangfu organs, focusing on the physiological connection and pathogenesis of three yin meridians of foot and zangfu organs. In the literature of Laoguanshan bamboo medical slips of Han Dynasty and lacquer figure of meridian points, the physiological connection between the yin meridians of hand and foot, and five zang organs, as well as the related diseases were further clarified; additionally, the meridian-zangfu theory had been developed in the field of diagnosis and treatment. In the era of Chapter of Meridians in Lingshu (Miraculous Pivot), there were up to 31 descriptions relevant with the connection of meridian distribution and zangfu physiological functions. It marks the construction of the "circular" flow of meridians and the interior-exterior communication of zang and fu organs; and enriches the knowledge in diseases, diagnosis and treatment with meridians and zangfu organs involved. The review on the evolution of the meridian-zangfu theory is conductive to supplementing and improving the development history of this theory of early time, and further recognizing its development rules and value. The maturity of this theoretical system not only links the meridians with the five zang and six fu organs, but also provides an important theoretical basis for the diagnosis and treatment of traditional Chinese medicine.

Objective To explore the changes in serum energy metabolites in patients with peripheral T-cell lymphoma,and investigate serum biomarkers for monitoring peripheral T-cell lymphoma from the perspective of energy metabolism.Methods Multiple/selected reaction monitoring(MRM/SRM)was used to detect the energy-related metabolites in the sera of 16 patients with newly diagnosed peripheral T-cell lymphoma admitted in the Hematology Medical Center of the Second Affiliated Hospital of Army Medical University from November 2020 to December 2021,as well as 10 recruited healthy volunteers.The corresponding clinical data including medical history,laboratory results and image data were collected and retrospectively analyzed.Results Significant differences were seen in the contents and expression profiles of serum energy metabolism-related products between the patients and the healthy volunteers.The patients had significantly reduced serum contents of cyclic AMP,succinate,citrate and cis-aconitate(P＜0.05),and elevated D-glucose 6-phosphate content(P＜0.05).The serum contents of citrate and succinate were negatively correlated with the risk stratification(low-,moderate-and high-risk)and clinical stage of the disease(P＜0.05).Meanwhile,there was a negative correlation between the contents of L-malic acid and citrate and the mid-term efficacy evaluation results,such as complete/partial response(CR/PR)or stable disease(SD)(P＜0.05).For patients with extranodal NK/T cell lymphoma(n=10),there were also significant reductions in the contents of cyclic AMP,succinate,citrate,isocitrate and cis-aconitate in the sera of patients compared with healthy volunteers(P＜0.05),and the contents of citrate and succinate were negatively correlated with the clinical stage(P＜0.05)and were rather correlated with mid-term efficacy evaluation results(CR/PR or SD)(P＜0.05).For patients with angioimmunoblastic T-cell lymphoma(n=6),the serum contents of cyclic AMP,citrate and succinate were significantly lower,while the content of D-glucose 6-phosphate was higher when compared with the healthy volunteers(P＜0.05),and the content of succinate was negatively correlated with both clinical stage and risk grade of the patients(P＜0.05).Conclusion There are 5 serum differential metabolites identified between patients with peripheral T-cell lymphoma and healthy controls,and succinate and citrate are expected to be serum biomarkers of peripheral T-cell lymphoma.

Objective To investigate the effect of catalpol(CAT)on necrotic apoptosis in acute myocardial infarction(AMI)rats.Methods Rat AMI model was constructed by ligating the anterior descending branch of the left coronary artery.Sixty SPF grade SD male rats were randomly grouped into sham surgery group(Sham group),AMI model group(Model group),low-dose CAT group(CAT-L group,30 mg·kg-1 CAT),high-dose CAT group(CAT-H group,60 mg·kg-1 CAT),and high-dose CAT+RIP1 activator recombinant RIP1 group(CAT-H+rRIP1 group,60 mg·kg-1 CAT+8 μg·kg-1 rRIP1),12 in each group.CAT was administered by gavage once a day for a total of 4 weeks.Recombinant RIP1 was administered via tail vein injection and the next day for a total of 4 weeks.Sham group and Model group were given equal amounts of physiological saline by gavage and tail vein injection,respectively.The CAT-L group and CAT-H group were injected with physiological saline via the tail vein the next day while receiving gastric lavage.TUNEL staining was applied to observe the apoptosis of rat cardiomyocytes.Western Blot was applied to detect the expression of RIP1/RIP3/MLKL signaling pathway related proteins in rat myocardial tissue.Results The apoptosis rates of myocardial cells in the sham group,model group,CAT-L group,CAT-H group,and CAT-H+rRIP1 group were(4.23±0.63)％,(33.48±3.94)％,(13.50±1.86)％,and(29.62±3.08)％,respectively;the expression levels of RIP1 protein in myocardial tissue were 0.21±0.02,0.86±0.09,0.43±0.04,and 0.72±0.07,respectively;the expression levels of RIP3 protein were 0.30±0.03,0.94±0.09,0.49±0.05,and 0.83±0.08,respectively;the phosphorylation levels of MLKL protein were 0.35±0.04,1.13±0.11,0.64±0.06,and 0.97±0.10,respectively.The above indexes in Model group were compared with those in Sham group,and those in CAT-H group were compared with those in Model group and CAT-H+rRIP1 group,and the differences were statistically significant(all P＜0.05).Conclusion CAT may inhibit necrotic apoptosis of myocardial cells in AMI rats by down-regulating the RIP1/RIP3/MLKL signaling pathway.

Mycotoxins are secondary metabolites produced by pathogenic fungi.They often contaminate various crops,and are detrimental to human and animal health.Mycotoxins have a variety of toxic effects,such as neurotoxicity,hepatotoxicity,immunotox-icity,teratogenicity,and carcinogenicity.However,the mechanism of immunotoxicity is still unclear.Dendritic cells(DCs),as the most potent antigen presenting cells,play a vital role in initiating innate and adaptive immune responses.Previous studies have found that mycotoxins can affect the endocytosis of DCs,the ability to stimulate T cell activation,the secretion of cytokines and chemokines.Thus,this review is aim to summarize the effects of mycotoxins on DCs-mediated immune responses,which may provide reference for researches to clarify the immunotoxicity mechanism of mycotoxins.
