ObjectiveTo investigate the mechanism by which Notoginsenoside R1 （NGR1） ameliorates hypoxia/reoxygenation （H/R）-induced injury in AC16 human cardiomyocyte cell lines through the regulation of mitophagy. MethodsCommon genes linked to hypoxia/reoxygenation injury and mitophagy were identified by intersecting data from GeneCards and MitoCarta databases. AC16 cell viability was assessed via CCK-8 assay under varying NGR1 concentrations （0， 6.25， 12.5， 25， 50， 100， 200， 300， 400， 500 μmol/L）. AC16 cells were divided into the following groups： control group （Control）， model group （H/R）， and treatment groups （H/R + NGR1 at 100， 200 and 300 μmol/L）. Mitochondrial membrane potential （ΔΨm） was measured using 5，5'，6，6'-tetrachloro-1，1'，3，3'-tetraethylbenzimidazolylcarbocyanine iodide （JC-1） staining. Transcriptional levels of mitophagy-related genes （Parkin， Pink1， P62） were quantified by reverse transcription-quantitative PCR （RT-qPCR）. Protein expression of mitophagy-related markers （Parkin， Pink1， P62， and LC3BⅡ） was evaluated via Western blot analysis. Mitochondrial ultrastructure was visualized by transmission electron microscopy （TEM）. ResultsCompared to the control group， cell viability in the H/R group significantly decreased （P<0.01）. Treatment with NGR1 at concentrations above 100 μmol/L significantly enhanced the cell viability of AC16 cells compared to the H/R group （P<0.01）. H/R induced a significant decrease in mitochondrial membrane potential （P<0.01）， which was restored by NGR1 treatment （P<0.01）. The mRNA levels of Parkin， Pink1， and P62 in the H/R group were upregulated compared to the control group （P<0.05）， while NGR1 intervention downregulated their expression （P<0.05）. Protein expression levels of Parkin， Pink1， and LC3BⅡ in the H/R group significantly increased， while P62 expression decreased compared to the control group （P<0.01）. In contrast， different doses of NGR1 treatment significantly reduced the expression of Parkin， Pink1， and LC3BⅡ while increasing P62 expression （P<0.05）. TEM revealed that the mitochondrial structure in the H/R group was severely disrupted， with fragmented and disorganized cristae， which was alleviated by NGR1. ConclusionNGR1 ameliorates H/R-induced AC16 cell injury， and its mechanism may be associated with modulating the Pink1/Parkin pathway to suppress excessive mitophagy.

Objective To investigate the predictive value of changes in various indicators of routine blood tests for the severity of brain damage in patients with acute cerebral hemorrhage(ACH)in high-altitude regions.Methods A retrospective analysis was conducted using data from 249 inpatients diagnosed with ACH at a hospital in Xizang.Patient data,including demographic information and results of routine blood tests,were collected.Based on their Glasgow Coma Scale(GCS)scores,the patients were divided into 2 groups,a mild brain damage group(GCS≥13 points)and a moderate-to-severe brain damage group(GCS≤12 points).Demographic information and laboratory test results were compared between the two groups.Binary logistic regression analysis was performed to examine the relationship between indicators of routine blood tests and the severity of brain damage,and key indicators were identified.The receiver operating characteristic(ROC)curve analysis was used to evaluate the predictive performance of key indicators in various combinations for the severity of brain injury in ACH patients.Results The moderate-to-severe group had a higher proportion of high-altitude residents,as well as elevated levels of white blood cells(WBC),neutrophils(N),neutrophil-to-lymphocyte ratio(NLR),systemic inflammatory index(SII),neutrophil-to-platelet ratio(NPR),and C-reactive protein(CRP)-to-lymphocyte ratio(CLR),compared to the mild group.On the other hand,the levels of lymphocytes(L),platelets(PLT),and platelet-to-albumin ratio(PAR)in the moderate-to-severe group were lower than those in the mild group.Binary logistic regression analysis showed that WBC(OR=1.221,95%CI:1.127-1.322),CRP(OR=1.019,95%CI:1.004-1.033),CRP-to-albumin ratio(CAR)(OR=1.845,95%CI:1.137-2.996),and CLR(OR=1.018,95%CI:1.005-1.030)were positively associated with moderate-to-severe brain damage,and that their elevated levels were associated with an increase in risk by the corresponding folds.PAR(OR=0.845,95%CI:0.721-0.990)was negatively correlated with moderate-to-severe brain damage,with an increase resulting in a reduction of risk by 0.845 times.ROC curve analysis showed that,in the mild group,the combined AUC for WBC+CRP was 0.689(optimal cutoff value 0.19,specificity 0.776,95%CI:0.624-0.755);the PAR+CAR+CLR combination(CAR was not significant,P>0.05)had an AUC of 0.675(optimal cutoff value 0.19,specificity 0.760,95%CI:0.609-0.741);the key indicator combination of WBC+PAR+CLR(CRP was not significant,P>0.05)demonstrating the strong predictive performance moderate-to-severe brain damage,yielding an AUC of 0.737(optimal cutoff value 0.08,specificity 0.624,95%CI:0.676-0.798).Conclusion The indicator combinations of WBC+CRP,PAR+CLR,and WBC+PAR+CLR exhibit significant value for predicting the severity of brain injury in ACH patients and may serve as potential predictive tools for the severity of brain damage in patients with acute cerebral hemorrhage in high-altitude regions.

Objective To investigate the independent risk factors affecting the prognosis of chronic active antibody-mediated rejection (caAMR) after kidney transplantation. Methods A retrospective analysis was conducted on 61 patients who underwent renal biopsy and were diagnosed with caAMR. The patients were divided into caAMR group (n=41) and caAMR+TCMR group (n=20) based on the presence or absence of concurrent acute T cell-mediated rejection (TCMR). The patients were followed up for 3 years. The value of 24-hour urinary protein and estimated glomerular filtration rate (eGFR) at the time of biopsy in predicting graft loss was assessed using receiver operating characteristic (ROC) curves. The independent risk factors affecting caAMR prognosis were analyzed using the LASSO-Cox regression model. The correlation between grouping, outcomes, and Banff scores was compared using Spearman rank correlation matrix analysis. Kaplan-Meier analysis was used to evaluate the renal allograft survival rates of each subgroup. Results The 3-year renal allograft survival rates for the caAMR group and the caAMR+TCMR group were 83% and 79%, respectively. The area under the ROC curve (AUC) for predicting 3-year renal allograft loss was 0.83 ［95% confidence interval (CI) 0.70-0.97］ for eGFR and 0.78 (95% CI 0.61-0.96) for 24-hour urinary protein at the time of biopsy. LASSO-Cox regression analysis and Kaplan-Meier analysis showed that eGFR≤25.23 mL/(min·1.73 m²) and the presence of donor-specific antibody (DSA) against human leukocyte antigen (HLA) class I might be independent risk factors affecting renal allograft prognosis, with hazard ratios of 7.67 (95% CI 2.18-27.02) and 5.13 (95% CI 1.33-19.80), respectively. A strong correlation was found between the Banff chronic lesion indicators of renal interstitial fibrosis and tubular atrophy (P<0.05). Conclusions The presence of HLA class I DSA and eGFR≤25.23 mL/(min·1.73 m²) at the time of biopsy may be independent risk factors affecting the prognosis of caAMR.

The occurrence and development of tumors are determined by both intrinsic and microenvironmental factors. The components of the tumor microenvironment exhibit great heterogeneity resulting in either pro-tumor or anti-tumor effects. The deep exploration of tumor immune microenvironment gave birth to the hypothesis of cancer immunoediting, which is supported by more and more evidence. Cancer immunoediting is accomplished through the interactions among various cells and factors in the microenvironment. While many molecular mechanisms have been studied, the cellular mechanisms of cancer immunoediting have been paid attention. This article explores the roles of cellular mechanisms in the cancer immunoediting, including immunogenic cell death, cellular senescence and neutrophil extracellular trap. The elucidation of these mechanisms not only reveals the complexity of the pathogenesis and progression of tumors, but also provides new targets and prognostic indicators for the diagnosis and treatment of tumors.

OBJECTIVE To compare the efficacy and safety of lacosamide （LCM） and carbamazepine （CAR） as monotherapy in the treatment of adult patients with newly diagnosed epilepsy. METHODS By methods of retrospective analysis， 84 adult patients with newly diagnosed epilepsy， were admitted to the Department of Neurology， Huaihe Hospital of Henan University during Sept. 2020-Jun. 2022， were divided into the control group （40 cases， receiving CAR treatment） and the observation group （44 cases， receiving LCM treatment） according to different medication regimens. Total response rate， epilepsy seizure frequency， blood lipid levels， and the occurrence of adverse events （AEs） of patients were compared between the 2 groups. RESULTS In the first month after treatment， there was no statistically significant difference in the total response rate between the observation group （63.64%） and the control group （55.00%， P＞0.05）； the frequency of epilepsy seizure in both groups was significantly reduced compared to before treatment （P＜0.05）， but there was no statistically significant difference between 2 groups （P＞0.05）. In the third month after treatment， the total response rate of the observation group （90.91%） was significantly higher than control group （67.50%， P＜0.05）； the frequencies of epilepsy seizure in both groups were significantly reduced compared to before treatment， and the observation group was significantly lower than the control group （P＜0.05）. In the third month after treatment， the levels of total cholesterol （TC）， triglyceride （TG） and low-density lipoprotein cholestrol （LDL-C） in the control group and the level of LDL-C in the observation group were significantly higher than before treatment， and the levels of TC， TG and LDL-C in the observation group were significantly lower than those in the control group （P＜0.05）. There was no statistically significant difference in the incidence of AEs between the observation group （15.91%） and the control group （17.50%， P＞0.05）. CONCLUSIONS Both LCM and CAR have certain effects in the treatment of newly diagnosed epilepsy in adults， which can reduce the frequency of epilepsy seizure in patients and have comparable safety. Meanwhile， LCM has better long-term efficacy than CAR in treating newly diagnosed epilepsy in adults， and its impact on the patient’s blood lipid is smaller than CAR.
