Objective:This study investigated the expression level of phosphatidylserine-specific phospholipase A1(PLA1A)in colorectal can-cer(CRC)and analyzed its correlations with clinicopathological features,prognosis,and immune infiltration.Methods:The expression level of PLA1A in CRC was screened,and the influence of this expression level on patient prognosis was analyzed using bioinformatics methods.A cohort of 192 patients diagnosed with CRC at Shanxi Province Cancer Hospital from January to December 2020 were selected.The PLA1A ex-pression level in those with CRC was determined using immunohistochemistry(IHC)and real-time quantitative reverse transcription PCR(RT-qPCR).The relationship between PLA1A level and the clinicopathological features of the patients with CRC was analyzed using the chi-square test.The expression levels of immune cell markers CD4 and CD8 as well as immunosuppressive checkpoints PD-1,TIM-3,and CTLA-4 in CRC were detected via IHC,and their correlations with PLA1A level were analyzed using the chi-square test.Results:The results of bioinformatics analysis showed that the expression level of PLA1A in CRC tissue was higher than paracancerous tissue,which correlated with overall surviv-al(OS)(P<0.05).The IHC and RT-qPCR results showed that PLA1A expression level was significantly upregulated in CRC tissiue(P<0.05).High PLA1A level was closely associated with the TNM stage,degree of differentiation,and lymph node metastasis(P<0.05).The IHC results demonstrated that PLA1A positively correlated with the infiltrating CD8+T cell level(P<0.05).In addition,the elevated PLA1A levels upregu-lated the expressions of immunosuppressive checkpoints PD-1,TIM-3,and CTLA-4(P<0.05).Conclusions:PLA1A is highly expressed in CRC,which is closely related to immune infiltrating cells and immunosuppressive checkpoints,suggesting that PLA1A plays an important role in immune infiltration in CRC,a finding that provides guidance in the treatment of CRC.

In recent years, programmed death-1/programmed death-ligand 1 inhibitors, as representatives of immune checkpoint inhibitors (ICIs), have become an important advancement in the field of tumor therapy, significantly improving the survival and prognosis of tumor patients. However, immune-related adverse events associated with ICIs treatment pose challenges for clinical management. In particular, the emergence of active tuberculosis and reactivation of latent tuberculosis infection has attracted attention, and its mechanism may be closely related to the overactivation of the immune system and the changes of host-pathogen relationship. How to effectively predict and manage these adverse reactions has become a hot topic of current research.

Objective To analyze the in-hospital and long term prognosis of acute myocardial infarction(AMI)patients with N-terminal B-type brain natriuretic peptide(NT-proBNP)peak value exceeding the up-per limit.Methods A total of 669 patients with AMI diagnosed in a hospital from 2013 to 2018 were selected as research objects.According to the peak value level of NT-proBNP,they were divided into the NT-proBNP peak value exceeding the upper limit group(50 cases)and the NT-proBNP peak value detectable group(619 cases).Propensity score was used for matching(1:2),and the patients were divided into NT-proBNP peak value exceeding the upper limit group(50 cases)and NT-proBNP peak value detectable group(107 cases),and the in-hospital prognosis and long-term prognosis of the two groups were compared,as well as the echo-cardiographic indexes of each group in the acute stage and recovery stage of AMI.Multiple linear regression a-nalysis was used to predict the factors affecting left ventricular ejection fraction in the recovery stage of AMI.Results After matching the propensity score,compared with the NT-proBNP peak value detectable group,the neutrophil to lymphocyte ratio,hypersensitive C reactive protein level and fibrinogen level in the NT-proBNP peak value exceeding the upper limit group were higher at admission,and the differences were statistically sig-nificant(P＜0.05).The proportion of Killip≥ Grade Ⅱ,left ventricular ejection fraction,hospitalization time and major adverse cardiovascular and cerebrovascular events in the NT-proBNP peak value exceeding the up-per limit group were compared with those in the NT-proBNP peak value detectable group,and the differences were statistically significant(P＜0.05).The left ventricular ejection fraction and left ventricular shortening fraction of the NT-proBNP peak value detection group in AMI acute stage were higher than those in the NT-proBNP peak value exceeding the upper limit group in AMI acute stage,and the difference was statistically significant(P＜0.05).Multiple linear regression analysis showed the relationship between the NT-proBNP peak value during hospitalization and the left ventricular ejection fraction of cardiac function during AMI re-covery.The results suggested that the NT-proBNP peak value was not a risk factor affecting the left ventricu-lar ejection fraction of cardiac function during AMI recovery.Conclusion AMI patients with NT-proBNP peak value exceeding the upper limit should be treated with a series of comprehensive treatment strategies to pro-mote their rehabilitation and improve their long-term prognosis.

Objective To analyze the clinical significance and predictive indicators of N-terminal pro-brain natriuretic peptide(NT-proBNP)levels exceeding the upper limit of detection range in acute myocardial infarction(AMI).Methods A total of 669 pa-tients with AMI were enrolled and divided into two groups based on their peak NT-proBNP levels:exceeding the upper limit of detection range group(n=50)and detectable group(n=619).The two groups were matched using propensity score matching(1∶2).The clinical and laboratory indicators,coronary artery features,and in-hospital prognosis were compared,and multivariate Logistic regression analysis was used to explore early predictive indicators of NT-proBNP exceeding the upper limit of detection range.Results The neutrophil-to-lymphocyte ratio(NLR),high-sensitivity C-reactive protein levels,and fibrinogen levels were higher in the group with NT-proBNP levels exceeding the upper limit of detection range.These findings were consistent after propensity score matching.In terms of in-hospital prognosis,patients in the group with NT-proBNP levels exceeding the upper limit of detection range had a higher propor-tion of Killip class 2 or higher,longer hospital stays,lower left ventricular ejection fraction,and higher incidence of major adverse cardio-vascular and cerebrovascular events.These findings remained consistent after propensity score matching,but there was no statistically sig-nificant difference in peak myocardial enzyme levels between the two groups before and after propensity score matching.Multivariate Logis-tic regression analysis showed that early predictive indicators of NT-proBNP exceeding the upper limit of detection range included higher NLR,lower use of antiplatelet drugs,high fibrinogen levels,left anterior descending branch occlusion,and older age.After propensity score matching,the predictive indicators of NT-proBNP exceeding the upper limit of detection range were right coronary artery occlusion,high NLR,high fibrinogen levels,and left anterior descending branch occlusion.Conclusion AMI patients with NT-proBNP levels ex-ceeding the upper limit of detection range have poorer in-hospital prognosis.NLR and fibrinogen levels on admission can serve as early predictive indicators of NT-proBNP levels exceeding the upper limit of detection range.

Objective: To explore the feasibility of remotely obtaining complex information on traditional Chinese medicine (TCM) pulse conditions through voice signals. Methods: We used multi-label pulse conditions as the entry point and modeled and analyzed TCM pulse diagnosis by combining voice analysis and machine learning. Audio features were extracted from voice recordings in the TCM pulse condition dataset. The obtained features were combined with information from tongue and facial diagnoses. A multi-label pulse condition voice classification DNN model was built using 10-fold cross-validation, and the modeling methods were validated using publicly available datasets. Results: The analysis showed that the proposed method achieved an accuracy of 92.59% on the public dataset. The accuracies of the three single-label pulse manifestation models in the test set were 94.27%, 96.35%, and 95.39%. The absolute accuracy of the multi-label model was 92.74%. Conclusion Voice data analysis may serve as a remote adjunct to the TCM diagnostic method for pulse condition assessment.
