Traditional Chinese medicine （TCM） therapy has unique clinical advantages in the treatment of atrial fibrillation， mainly reflected in five aspects， improving quality of life， enabling early diagnosis and treatment， promoting cardiac rehabilitation， making up for the limitations of Western medicine， and improving the success rate of catheter ablation. However， there is insufficient evidence in current clinical research. Based on the current status of TCM research in the treatment of atrial fibrillation， it is suggested that future studies should focus on standardized research on syndrome differentiation and classification. This can be achieved through clinical epidemiological surveys， expert consensus， and other methods to establish a unified syndrome differentiation and classification standard for atrial fibrillation. Clinical efficacy evaluation indicators should be standardized， and core outcome measures for clinical research on TCM treatment of atrial fibrillation should be developed through systematic reviews， patient interviews， and other methods. Additionally， clinical research design， implementation， and data management should be improved. By leveraging modern information technologies such as artificial intelligence， the scientific and standardized nature of TCM intervention research on atrial fibrillation can be enhanced， ultimately improving the quality of research.

Objective To investigate the effect of loganin(Log)on glutamine metabolism in cervical cancer through the regula-tion of nuclear factor red blood cell 2 related factor 2(NFE2L2)-ferritin heavy chain 1(FTH1)-glutathione peroxidase 4(GPX4).Methods Bioinformatics analysis was conducted to identify common targets of Log,glutamine metabolism,and cervical cancer.Hela cells were divided into Blank,control(Ctrl),Log,cisplatin(DDP),NFE2L2 activator(TBHQ),NFE2L2 inhibitor(ML385),and TBHQ+Log groups to detect cell proliferation,invasion,apoptosis,glutamine metabolism,and the protein expression of NFE2L2,FTH1,and GPX4.A cervical cancer xenograft mouse model was established to investigate the in vivo effects of Log on the progression of cervical cancer.Results Bioinformatics analysis confirmed that NFE2L2 might be a target of Log in the treatment of cervical cancer.Both Log and DDP reduced the proliferation and invasion abilities of Hela cells,increased apoptosis,and decreased the levels of glutamine and glutamic acid,as well as the protein expression of glutaminase(GLS1)and glutamic dehydrogenase(GLUD1,P<0.05).The NFE2L2 activator TBHQ had opposite effects,whereas ML385 had a similar impact on the Log.Additionally,Log treatment inhibited the protein expression of NFE2L2,FTH1,and GPX4(P<0.05).Animal experiments showed that Log significantly inhibited cervical cancer progression(P<0.05).Conclusion Log affects cervical cancer progression via glutamine metabolism by inhibiting the NFE2L2-FTH1-GPX4 signaling pathway.

The paper reports a 32-year-old female acute myeloid leukemia patient who developed graft-versus-host disease after paternal hematopoietic stem cell transplantation, which subsequently led to renal thrombotic microangiopathy. She subsequently required a kidney transplant from the same donor 5 years later due to renal failure. Considering that both the bone marrow and kidney were from the same donor and the recovery of renal function was favorable, immunosuppressive therapy was discontinued after a short course of anti-rejection treatment, with maintained stable kidney function. This case suggests that under the condition of high chimerism, allogeneic hematopoietic stem cell transplantation and kidney transplantation from the same donor can achieve immune tolerance, potentially improving solid organ transplantation success rate. The findings provide a novel therapeutic approach for solid organ transplantation following allogeneic hematopoietic stem cell transplantation.

The neonatal mammalian heart has a remarkable regenerative capacity, while the adult heart has difficulty to regenerate. A metabolic reprogramming from glycolysis to fatty acid oxidation occurs along with the loss of cardiomyocyte proliferative capacity shortly after birth. In this study, we sought to determine if and how metabolic reprogramming regulates cardiomyocyte proliferation. Reversing metabolic reprogramming by carnitine palmitoyltransferase 1 (CPT1) inhibition, using cardiac-specific Cpt1a and Cpt1b knockout mice promoted cardiomyocyte proliferation and improved cardiac function post-myocardial infarction. The inhibition of CPT1 is of pharmacological significance because those protective effects were replicated by etomoxir, a CPT1 inhibitor. CPT1 inhibition, by decreasing poly(ADP-ribose) polymerase 1 expression, reduced ADP-ribosylation of dual-specificity phosphatase 1 in cardiomyocytes, leading to decreased p38 MAPK phosphorylation, and stimulation of cardiomyocyte proliferation. Our present study indicates that reversing metabolic reprogramming is an effective strategy to stimulate adult cardiomyocyte proliferation. CPT1 is a potential therapeutic target for promoting heart regeneration and myocardial infarction treatment.

Objective To investigate the impacts of usnea acid(UA)on the proliferation of human ovarian cancer(OC)cells.Methods Ovarian adenocarcinoma cells SKOV3 were randomly divided into control group,L-UA group,M-UA group,H-UA group(with 10,20,and 50 μmol/L UA added respectively),pcDNA3.1-NC group and pcDNA3.1-PD-1 group.RT-qPCR method was applied to detect the expression of programmed cell death 1(PD-1)and programmed cell death ligand 1(PD-L1)in SKOV3 cells.CCK-8 assay and plate method were applied to detect the effect of UA on SKOV3 cell proliferation.The effect of UA on SKOV3 cells apoptosis was examined by flow cytometry.Mouse ovarian epithelial cancer cell line ID8 cells were collected to construct an OC mouse model,and the mass and volume of OC tumors were recorded.Immuno-histochemical microscopy was applied to detect the infiltration of PD-1,PD-L1,and CD8+T cells.Results The PD-1 mRNA,PD-L1 mRNA,colony count,A450 val-ue,PCNA protein,PD-1 protein,and PD-L1 protein in the L-UA,M-UA,and H-UA groups were lower than those in the control group,the apoptosis rate and Bax protein were higher in the control group(P<0.05).Com-pared with the H-UA group and the pcDNA3.1-NC group,the PD-1 mRNA,PD-L1 mRNA,colony count,A450 value,PCNA protein,PD-1 protein,and PD-L1 protein in the pcDNA-3.1-PD-1 group increased and the apoptosis rate and Bax protein decreased(P<0.05).The quality,volume,positivity rate of PD-1and PD-L1 of OC tumors in the UA group was lower than that in the control group,the counting number of CD8+T cell infiltration was higher than control group(P<0.05).Conclusions UA may inhibit progression of OC cell line SKOV3 by regula-ting cell proliferation,apoptosis,and immune escape.

Objective:Based on the activities of Helicobacter pylori ( HP) screening in Jiangsu Province in 2024, to evaluate the overall management ability in HP screening, testing, treatment and follow-up in primary medical facilities. Methods:From May 15 to October 18, 2024, the data of HP screening and treatment were retrospectively collected from 79 township health centers, community hospitals, and community health service centers in Jiangsu Province. The rates of screening completion, urea breath test (UBT) completion, treatment rate, UBT follow-up completion, and HP eradication were analyzed. Chi-square test was used for statistical analysis. Results:The completion rate of HP screening was 94.45% (15 489/16 400). There were 6 604 cases (42.64%) with serum HP antibody positive among the 15 489 individuals who completed screening. The positive rate of serum HP antibody in males was higher than that in females (44.77%, 2 643/5 904 vs. 41.32%, 3 961/9 585), and the difference was statistically significant ( χ2=17.69, P<0.001). The positive rates of serum HP antibody in screened individuals aged 18 to 19, 20 to 39, 40 to 59, and 60 to 75 years old were 22.38% (32/143), 36.12% (1 168/3 234), 45.01% (3 240/7 199), and 44.05% (2 164/4 913), respectively, and the difference was statistically significant( χ2=100.73, P<0.001). Among the 6 604 HP antibody-positive individuals, 4 381 cases completed UBT, with a UBT completion rate of 66.34% (4 381/6 604). There were 3 197 individuals with both HP serum antibody and UBT positive, the consistency rate of the 2 tests was 72.97% (3 197/4 381). Totally 2 737 cases received treatment, with a treatment completion rate of 85.61% (2 737/3 197); 2 327 individuals underwent UBT follow-up, with a follow-up completion rate of 85.02% (2 327/2 737). During follow-up, the result of UBT was negative in 1 982 individuals, and the HP eradication rate was 85.17% (1 982/2 327). Conclusions:There are deficiencies in the completion rate of HP screening, testing, treatment, and follow-up in primary hospitals, especially in the completion rate of UBT, which may be related to cognitive insufficiency for HP in residents. It is necessary to strengthen the training of physicians′ abilities in primary hospitals, optimize the allocation of drug resources, enhance health education, and increase residents′ participation and compliance.

Objective:To explore the predictive potential of dual-energy CT (DECT) quantitative parameters in identifying breast cancer molecular subtypes and the expression of the epidermal growth factor receptor (EGFR) .Methods:A cohort of 97 breast cancer patients, treated between Jun. 2022 and Jun. 2024 were selected. The study compared DECT parameters-such as iodine concentration (IC) , normalized iodine concentration (NIC) , spectral curve slope (λ HU) , and effective atomic number (Z eff) in both arterial and venous phases across different molecular subtypes. A multiclass logistic regression model was employed to assess the parameters' value in predicting molecular subtypes, while a binary logistic regression model was used to evaluate their predictive value for EGFR expression. Results:Multiple Logistic regression analysis showed that after adjusting for confounder age and family history, IC ( OR=1.72, 2.78, 3.05) , NIC ( OR=2.52, 1.94, 2.93) , λ HU ( OR=2.08, 2.54, 3.17) and Z eff ( OR=2.03, 2.30, 2.37) at arterial stage were independently correlated with the molecular subtypes of breast cancer ( P<0.05) . Binary logistic regression analysis, adjusted for tumor size and lymph node metastasis, identified arterial phase IC ( OR=3.45) , NIC ( OR=2.73) , λ HU ( OR=2.59) , and Z eff ( OR=1.76) as independent risk factors for EGFR-positive breast cancer ( P<0.05) . Conclusion:DECT quantitative parameters, particularly arterial phase IC, NIC, λ HU, and Zeff, offer valuable insights into the molecular subtyping of breast cancer and EGFR expression, thereby assisting in the development of personalized treatment strategies.
