Objective:To investigate the protective effect of prunetin on the neurons in the rats with cerebral ischemia reperfusion injury(CIRI),and to clarify its possible mechanisms.Methods:Thirty-six SD rats were randomly divided into sham operation group,model group,low dose of prunetin group(3.5 mg·kg-1),medium dose of prunetin group(7.0 mg·kg-1),high dose of prunetin group(14.0 mg·kg-1),and positive drug edaravone(Eda)group(n=6).Zealonga method was used to evaluate the neurological function damage of the rats in various groups;open field experiment was used to evaluate the autonomous motor function;Triphenyltetrazolium chlorde(TTC)staining was used to evaluate the areas of cerebral infarction of the rats in various groups;HE staining and Nissl staining were used to observe the pathomorphology of brain tissue of the rats in various groups.Additionally,twenty-one SD rats were randomly divided into sham operation group,model group,prunetin group,c-Jun N-terminal kinase(JNK)inhibitor group,p38 inhibitor group,JNK inhibitor+prunetin group,and p38 inhibitor+prunetin group(n=3).TUNEL staining was used to detect the positive rates of apoptosis of neurons of the rats in various groups;Western blotting method was used to detect the expression levels of apoptosis-related proteins and JNK/p38 signaling pathway-related proteins in brain tissue of cerebral infarction side of the rats in various groups.Results:Compared with sham operation group,the neurological deficit score of rats in model group was significantly increased(P＜0.001),the total motor distance was shortened(P＜0.001),and the ratio of cerebral infarction area was increased(P＜0.001).In sham group,the neuronal structure in the rat brain tissue was clear and well-organized,with an abundance of Nissl bodies and no apparent pathological changes observed.Compared with model group,the neurological deficit scores of the rats in medium and high doses of prunetin groups were decreased(P＜0.05),total motor distances of rats were increased(P＜0.05),and the cerebral infarction areas of rats were decreased(P＜0.05);the neurons showed disarrayed arrangement,cytoplasmic condensation,nuclear consolidation,and lysing and deletion of Nissl bodies were decreased.Compared with sham operation group,the positive rate of apoptosis of neurons in model group was significantly increased(P＜0.001),the expression level of B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax)and cleaved Caspase-3 proteins in brain tissue of the rats were significantly increased(P＜0.05 or P＜0.01).Compared with model group,the positive rats of apoptosis of neurons of the rats in prunetin group were decreased(P＜0.05),the expression level of Bcl-2 protein in brain tissue of the rats was increased(P＜0.001),and the expression levels of Bax and cleaved Caspase-3 proteins were significantly decreased(P＜0.05).Compared with inhibitor groups,the positive rates of apoptosis of neurons in inhibitor+prunetin groups were decreased(P＜0.01),and the expression levels of p-JNK and p-p38 proteins in brain tissue of the rats as well as the ratios of p-JNK/JNK and p-p38/p38 were decreased(P＜0.05).Conclusion:Prunetin has the effect of reducing the neurological function damage,decreasing the area of cerebral infarction,reducing the pathological damage,and inhibiting neuronal apoptosis in the rats,and its mechanism may be related to inhibiting neuronal apoptosis through regulating the JNK/p38 signaling pathway.

Objective:To investigate the consistency and sensitivity of minimal residual disease (MRD) detected by multicolor flow cytometry (FCM) and real-time quantitative polymerase chain reaction (RQ-PCR) in patients with acute myeloid leukemia (AML) accompanied by monocytic differentiation after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:A retrospective case series study was conducted. A total of 218 patients diagnosed with AML accompanied by monocytic differentiation who underwent allo-HSCT in Peking University People's Hospital between January 2017 and December 2021 were included. MRD was detected by using bone marrow FCM and RQ-PCR at predefined intervals (at 1-, 2-, 3-, 4.5-, 6-, 9-, and 12-month before and after transplantation). Patients were grouped based on AML-related specific genes, and dynamic changes in MRD results detected by FCM and RQ-PCR after transplantation were analyzed to evaluate the correlation with post-transplant relapse.Results:A total of 218 enrolled patients included 114 males and 106 females, with the median age of 32 years (1-65 years). The median follow-up duration was 218 d (21-1 541 d). Hematologic relapse occurred in 26 patients (12.7%), with a median relapse time of 272 d (83-934 d); 35 patients (15.9%) died, including 15 (6.9%) due to leukemia relapse and 20 (9.2%) due to transplant-related mortality. Predictive markers for relapse included once WT1 positive (WT1+once), twice WT1 positive (WT1+twice), CBFβ::MYH11 fusion genes positive, mixed-lineage leukemia (MLL)-related fusion genes positive, AML1::ETO fusion genes positive, and once FCM positive (FCM+once), twice FCM positive (FCM+twice). The overall consistency rate between FCM and RQ-PCR for MRD detection in AML patients accompanied by monocytic differentiation after transplantation was 75.7% (165/218). The consistency rate of MRD detection results in WT1+once, WT1+ twice, MLL-related fusion gene positive, and NPM1 gene mutation positive with FCM was higher than the average value (>75.7%), while the consistency rate of MRD detection results in AML1::ETO and CBFβ::MYH11 fusion gene positive with FCM was lower than the average value (<75.7%). Notably, persistent low-level positivity without relapse after transplantation occurred in cases with WT1 (15 patients), NPM1 (2 patients), CBFβ::MYH11 (11 patients), or AML1::ETO (2 patients); in contrast, MLL-related fusion genes (particularly MLL::AF6 and MLL::AF9) positive after transplantation indicated relapse in patients. The sensitivity and specificity of RQ-PCR for MRD monitoring varied by genetic markers: WT1+once and WT1+twice (sensitivity: 66.7%, 50.0%; specificity: 84.5%, 91.1%, respectively), AML1::ETO (sensitivity: 100.0%; specificity: 50.0%), CBFβ::MYH11 (sensitivity: 100.0%; specificity: 58.6%), MLL-related fusion genes (sensitivity: 75.0%; specificity: 96.4%), and NPM1 (sensitivity: 75.0%; specificity: 91.7%).Conclusions:The sensitivity and specificity of AML-related genetic markers for recurrence prediction show differences. Discrepancies between RQ-PCR and FCM in MRD detection are notable in AML with monocytic differentiation after transplantation. FCM exhibits relatively lower sensitivity for MRD monitoring in this subtype, while RQ-PCR based on AML-related genes may compensate for FCM limitations.

Objective To explore the relationship between pathogenic microorganism types,age and season in 2 188 children with respiratory tract infections.Methods A total of 2 188 children with respiratory tract in-fections admitted to the Department of Pediatrics,962 Hospital,Joint Logistic Support Force of PLA from June 2023 to May 2024 were selected as the study subjects.Targeted next generation sequencing(tNGS)tech-nology was used to detect 107 common pathogenic microorganism in children with respiratory tract infections,including Haemophilus influenzae,rhinovirus,Moraxella catarrhalis,Mycoplasma pneumoniae,Staphylococcus aureus,Streptococcus pneumoniae,human parainfluenza virus,human respiratory syncytial virus,etc.The re-spiratory tract infection situation and epidemiological characteristics of children in Harbin were analyzed.Re-sults Among 2 188 pediatric patients,98.5%(2 156/2 188)tested positive for pathogenic microorganism,with Haemophilus influenzae accounting for the highest proportion of 33.5%(732/2 188),followed by rhino-virus of 25.0%(547/2 188)and Moraxella catarrhalis of 24.8%(543/2 188).The positive rates of Hae-mophilus influenzae and human adenovirus in male children were higher than those in female children(P<0.05),while there were no statistically significant differences in the positive positive rates of other pathogenic microorganism between male and female children(P>0.05).Except for human adenovirus and influenza A virus,which showed no statistically significant differences in positive rates among different age groups(P>0.05),there were statistically significant differences in the positive rates of other pathogenic microorganism a-mong different age groups(P<0.05).The positive rates of pathogenic microorganism in preschool children were relatively high.There were no statistically significant differences in the positive rates of Streptococcus and Staphylococcus aureus in different seasons(P>0.05),while there were statistically significant differences in the positive rates of other pathogenic microorganism in different seasons(P<0.05).The positive rates of Haemophilus influenzae,Streptococcus pneumoniae,human metapneumovirus,human parainfluenza virus and SARS-Cov-2 were the highest in summer(P<0.05).Conclusion 2 188 children with respiratory tract infec-tions were mainly caused by pathogenic microorganism such as Haemophilus influenzae,rhinovirus,and Moraxella catarrhalis,etc.Preschool children is a susceptible group,and the prevalence of pathogenic microor-ganism varies seasonally.In clinical practice,relevant prevention and control measures should be developed based on this characteristic to reduce the incidence of diseases.

Objective To investigate the distribution and evolutionary patterns of traditional Chinese medicine(TCM)syndromes and syndrome elements during the malignant transformation from chronic pancreatitis(CP)to pancreatic intraepithelial neoplasia(Pan IN)and pancreatic ductal adenocarcinoma(PDAC).Methods A retrospective analysis was conducted on 710 patients(330 of CP,104 of Pan IN,276 of PDAC)diagnosed pathologically or clinically at Shanxi Institute of Traditional Chinese Medicine from January 2021 to June 2024.Data including demographics,laboratory results,and TCM diagnostic information were recorded using EpiData 3.1.Syndrome and syndrome-element patterns were determined via factor analysis and K-means clustering using SPSS 27.0.Results The study identifies seven TCM syndrome types in CP,Pan IN,and PDAC.Among CP patients,the syndrome distribution was primarily liver-gallbladder damp-heat syndrome(22.42％)and gastrointestinal excess-heat syndrome(20.91％),with excess syndromes accounting for a higher proportion(43.33％);the syndrome elements were mainly heat(51.52％)and dampness(35.15％),with the disease location in the pancreas,related to the liver,spleen,and stomach.In Pan IN patients,the syndrome distribution was mainly spleen deficiency with dampness obstruction(23.08％)and liver-gallbladder damp-heat syndrome(17.31％),with mixed deficiency-excess syndrome accounting for a higher proportion(30.00％);the syndrome elements were mainly heat(41.35％),dampness(40.38％),and qi deficiency(37.50％),with the disease location in the pancreas,related to the spleen and liver.In PDAC patients,the syndrome distribution was mainly spleen deficiency with dampness obstruction(29.71％)and qi-blood deficiency syndrome(20.29％),with deficiency syndromes accounting for a higher proportion(49.82％);the syndrome elements were mainly qi deficiency(50.00％)and dampness(36.23％),with the disease location in the pancreas,related to the spleen,kidney,and liver.Chi-square tests revealed significant differences in syndrome types(TCM syndromes:x2=100.419,P＜0.001;deficiency-excess syndromes:x2=73.722,P＜0.001),syndrome elements(x2=117.384,P＜0.001),and disease locations(x2=127.191,P＜0.001)across different stages of CP malignant transformation.During CP malignant progression,the proportion of excess syndromes gradually decreased(43.33％→12.32％),while deficiency syndromes increased(26.67％→49.82％).Excess syndrome elements(fire,heat,qi stagnation,blood stasis)decreased(53.48％→25.36％),whereas deficiency syndrome elements(qi deficiency,yin deficiency,yang deficiency,blood deficiency)increased(25.15％→49.64％).The disease location shifted from primarily the liver,spleen,and stomach in the inflammatory stage to the spleen and kidney in the cancerous stage.Conclusion The malignant transformation of CP basically involves the pancreas,is correlated early with liver and spleen-stomach and later with kidney,and exhibits a progression from excess to deficiency in the pattern of"deficiency interweaved with excess syndrome,transition from excess to deficiency,and progressive spleen deficiency".

BACKGROUND: Chronic kidney disease (CKD) poses a major global health challenge, often foreshadowing poor patient outcomes. The C-reactive protein to albumin ratio (CAR) serves as a pivotal biomarker, demonstrating a strong correlation with adverse outcomes in cardiovascular disease (CVD). This study sought to examine the correlation between CAR and the risk of all-cause and cardiovascular mortality in patients with CKD stages 3-5. METHODS: This study utilized data of CKD patients from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2010, with follow-up to December 31, 2019. The optimal CAR cutoff value was identified utilizing the method of maximally selected rank statistics. Multivariable Cox proportional hazards regression model, restricted cubic splines (RCS) model, and subgroup analysis were employed to assess the association between CAR and mortality among CKD patients. RESULTS: During a median (with interquartile range) follow-up period of 115 (112,117) months among 2,841 CKD individuals, 1,893 deaths were observed, including 692 deaths due to CVD events. Based on the RCS analysis, a non-linear correlation was observed between CAR and mortality. Using 0.3 as the optimal CAR cutoff value, the cohort was divided into high and low groups. In the fully adjusted model, CKD patients with high CAR values exhibited an elevated risk of all-cause mortality (hazard ratio [HR] 1.53, 95% confidence interval [CI] 1.28-1.83, P < 0.001) and cardiovascular mortality (HR 1.48, 95% CI 1.08-2.02, P = 0.014). Compared to the population aged >65 years (HR 1.32, 95% CI 0.99-1.76, P = 0.064), the risk of cardiovascular mortality was significantly higher in those aged ≤65 years (HR 2.19, 95% CI 1.18-4.09, P = 0.014) with elevated CAR levels. CONCLUSIONS A notable correlation exists between the elevation of CAR and increased all-cause and cardiovascular mortality, suggesting its potential as an independent indicator for evaluating the prognosis of patients with CKD stages 3-5.

OBJECTIVE: To assess the cardioprotective effect and impact of Qishen Granules (QSG) on different ischemic areas of the myocardium in heart failure (HF) rats by evaluating its metabolic pattern, substrate utilization, and mechanistic modulation. METHODS: In vivo, echocardiography and histology were used to assess rat cardiac function; positron emission tomography was performed to assess the abundance of glucose metabolism in the ischemic border and remote areas of the heart; fatty acid metabolism and ATP production levels were assessed by hematologic and biochemical analyses. The above experiments evaluated the cardioprotective effect of QSG on left anterior descending ligation-induced HF in rats and the mode of energy metabolism modulation. In vitro, a hypoxia-induced H9C2 model was established, mitochondrial damage was evaluated by flow cytometry, and nuclear translocation of hypoxia-inducible factor-1 α (HIF-1 α) was observed by immunofluorescence to assess the mechanism of energy metabolism regulation by QSG in hypoxic and normoxia conditions. RESULTS: QSG regulated the pattern of glucose and fatty acid metabolism in the border and remote areas of the heart via the HIF-1 α pathway, and improved cardiac function in HF rats. Specifically, QSG promoted HIF-1 α expression and entry into the nucleus at high levels of hypoxia (P<0.05), thereby promoting increased compensatory glucose metabolism; while reducing nuclear accumulation of HIF-1 α at relatively low levels of hypoxia (P<0.05), promoting the increased lipid metabolism. CONCLUSIONS QSG regulates the protein stability of HIF-1 α, thereby coordinating energy supply balance between the ischemic border and remote areas of the myocardium. This alleviates the energy metabolism disorder caused by ischemic injury.

The accumulation of uremic toxins such as urea nitrogen, blood creatinine, and uric acid of patients with renal failure in vivo would lead to aggravated kidney damage. In this study, coated aldehyde oxy-starch (CAO) was used as an adsorbent to investigate its in vitro adsorption performance on renal failure indexes for urea, indoxyl sulfate (INS), monomethylamine (MMA), dimethylamine (DMA), uric acid (UA), and creatinine (Cr). The effects of variables such as pH, temperature, concentration, dosage, and time on the adsorption capacity of CAO were systematically investigated, employing analytical techniques of high-performance liquid chromatography (HPLC) and gas chromatography (GC). The results revealed that CAO exhibited a strong adsorption capacity for urea, INS, and MMA, alongside a moderate adsorption capacity for DMA, UA, and Cr. The adsorption kinetics and thermodynamic studies indicated that the adsorption of urea and UA by CAO were fitted in pseudo-first-order kinetics, and the adsorption isotherm aligned with the Freundlich adsorption model. The enthalpy change ΔH of urea in adsorption was in the range of 40 to 60 kJ·mol^-1, which demonstrated the presence of strong adsorption force due to the interactions of coordinating groups. The ΔH of UA was greater than 80 kJ·mol^-1, indicating the generation of chemical bonds during the adsorption. Both of them, Gibbs free energy ΔG was less than 0, within the range of -20 to 0 kJ·mol^-1, suggested that the adsorption of urea and UA by CAO occurred spontaneously as physical adsorption process. The adsorption entropy ΔS of urea and UA was > 0, which indicated an increase in entropy throughout the adsorption. The infrared spectroscopygram showed the formation of a chemical bond, specifically the imine bond, following the adsorption of urea by CAO, thereby indicating a chemical reaction during the adsorption. This study elucidates the adsorption mechanism of CAO on various indexes of renal failure, providing a scientific basis for its clinical usage.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.
