Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10 /L vs preoperative 3.07×10 /L, P<0.001), with significant upregulation of CD11b (7.30×10 /L vs preoperative 3.05×10 /L, P<0.001) and CD54 (7.15×10 /L vs preoperative 2.99×10 /L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10 /L vs preoperative 1.12×10 /L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10 /L vs preoperative 1.12×10 /L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

Objective To develop a nomogram-based predictive model for assessing the risk of respiratory distress syndrome(RDS)in premature infants in the high-altitude region of Dali.The predictive performance and clinical applicability of the model will be systematically evaluated to provide evidence-based guidance for the early diagnosis and clinical management of respiratory distress in premature infants.Methods A total of 680 preterm infants admitted to the Dali Maternal and Child Health Hospital between January 2020 and December 2024 were enrolled in the study and randomly divided into a training set(n=476)and a validation set(n=204)at a ratio of 7∶3.Independent predictors were identified through univariate logistic regression and multivariate stepwise regression analyses,and a nomogram model was subsequently developed using R software.The performance of the model,including its discrimination,calibration,stability,and clinical applicability,was evaluated using the receiver operating characteristic curve(ROC),Hosmer-Lemeshow goodness-of-fit test,bootstrap resampling method,and decision curve analysis(DCA).Results The final model incorporated seven independent variables:gestational age,birth weight,Apgar score,blood oxygen saturation,gestational hyperglycemia,prenatal glucocor-ticoid therapy,and maternal history of infection.The areas under the curve(AUCs)for the training and validation sets were 0.88(95%CI:0.84～0.92)and 0.83(95%CI:0.76～0.89),respectively,with all Hosmer-Lemeshow test p-values exceeding 0.05.The bootstrap-corrected AUC was 0.85(95%CI:0.81～0.89).DCA indicated that the model achieved the highest net benefit at a risk threshold range of 10%to 35%.Conclusions This model integrates multiple risk factors associated with the occurrence of RDS in plateau environments,demonstrating robust predictive performance for RDS in preterm infants residing in high-altitude areas such as Dali.It can serve as a valuable tool for risk stratification and clinical decision-making,and may also provide a reference for future multicenter prospective studies.

Objective:To evaluate the safety and efficacy of accelerator-based boron neutron capture therapy (AB-BNCT) in the treatment of recurrent and refractory malignant tumors.Methods:The data of 14 patients admitted to Xiamen Humanity Hospital from September 2022 to April 2023 were prospectively collected, including 7 patients with primary brain malignancies and 7 patients with locally recurrent inoperable head and neck malignancies. All patients received intravenous infusion of boron drug (NBB-001, p-dihydroxyborylphe nylalanine, a patented freeze-dried formulation) at a total nominal dosage of 500 mg/kg (11 patients) or 750 mg/kg (3 patients), and were irradiated with neutrons (operating with NeuPex system). Adverse events after treatment were recorded and assessed. The primary efficacy endpoint was the 90 d objective response rate (ORR), while the secondary endpoints included progression-free survival (PFS) and complete response rate (CRR). Data were compiled and analyzed by SAS 9.4 software. The rate and 95% CI were calculated using Clopper-Pearson method. Results:The median dose delivered to 80% of the target volume (D 80%) was 16.80 GyE (range: 8.93-23.79 GyE). The most common adverse reactions were hyperamylasemia, alopecia, and hyperprolactinemia. Five patients experienced 8 cases of grade 3 or above adverse events, including 1 case of grade 4 acute kidney injury and 7 cases of grade 3 adverse events. All adverse events were recovered after observation or treatment. At 90 d after treatment, the ORR of all patients was 9/14 (64%, 95% CI: 35%-87%), disease control rate (DCR) was 10/14 (71%, 95% CI: 42%-92%), CRR was 2/14 (14%, 95% CI: 2%-42%); and the best overall response during the entire course included an ORR of 10/14 (71% ,95% CI: 42%-92%), DCR of 13/14 (93%, 95% CI: 66%-100%), and CRR of 3/14 (21% ,95% CI: 5%-51%). The 1-year survival rate for head and neck malignancies was 71.4%, and the 2-year survival rate was 42.8%. The 1-year survival rate for recurrent brain malignancies was 42.8%. Conclusion:AB-BNCT demonstrates favorable safety and promising efficacy in treating primary brain malignancies and recurrent/refractory head and neck malignancies, representing a potential therapeutic option.

The plants of the genus Caragana Fabr. are desert plants of the Leguminosae family, which are widely used in traditional ethnomedicine, with the effects of nourishing Yin and nourishing blood, dispelling wind and removing dampness, clearing heat and detoxifying toxins. The anti-inflammatory effect of Caragana Fabr. has attracted much attention, the research on the related mechanism has made some progress, but it lacks systematic collation. By summarising the anti-inflammatory effects of the active ingredients of Caragana Fabr., the authors found that they have good anti-inflammatory activities on different inflammatory cell models in vitro, and have good improvement effects on rheumatoid arthritis, colitis, complex nephritis, and acute lung injury and other disease models. The anti-inflammatory effects of the active components of this genus mainly include the reduction of the levels of a variety of pro-inflammatory factors, and the signalling pathways involved mainly include TLR4/NF-κB, TLR4/MAPK, TLR4/NF-κB/IRF3, JAK/STAT-1, ERK/STAT-1 and so on. Therefore, the paper mainly reviews the research progress on the anti-inflammatory effects and mechanisms of the Caragana Fabr. plants and their active components according to disease types, with a view to providing reference for the in-depth study of their anti-inflammatory activities and the development of new products with related functions.

Objective To systematically review the sex differences in efficacy of immune checkpoint inhibitors (ICIs) for non-small cell lung cancer (NSCLC) patients. Methods We conducted a computer search of Medline, The Cochrane Library, and EMbase from inception to November 2022 to identify randomized controlled trials (RCTs) assessing the efficacy of ICIs in patients with NSCLC. A meta-analysis was performed using RevMan 5.4 software. Results Finally 16 RCTs with a total of 9 653 patients were included, and the modified Jadad scale score was≥4 points. Meta-analysis results showed that in female NSCLC patients receiving immune therapy, the median overall survival (OS) [HR=0.72, 95%CI (0.61, 0.85), P<0.001] was longer than that in males [HR=0.73, 95%CI (0.69, 0.78), P<0.001]. Males [HR=0.64, 95%CI (0.58, 0.71), P<0.001] had an advantage over females [HR=0.76, 95%CI (0.57, 1.03), P=0.760] in median progression-free survival (PFS). Conclusion Females receiving ICIs have an advantage over males in terms of median OS. However, males tend to derive greater benefit from ICIs in terms of median PFS.

Objective To observe the clinical efficacy of Bushen Tongmai Prescription in treating type 2 diabetes mellitus(T2DM)complicated with atherosclerotic cardiovascular disease(ASCVD)of kidney deficiency and blood stasis type,and to investigate its effect on serum microRNA-126(miR-126).Methods Sixty patients with T2DM complicated with ASCVD of kidney deficiency and blood stasis type who admitted to the outpatient and inpatient departments of the Department of Geriatric Medicine of Shenzhen Traditional Chinese Medicine Hospital from March 2023 to October 2023 were randomly divided into the study group and the control group according to random number table method,with 30 patients in each group.All patients in the two groups were required to take low-salt and low-fat diabetic diet and exercise for intervention,and were also given the conventional western medical treatment with hypoglycemic,lipid-lowering,antihypertensive,anti-platelet aggregation agents.Additionally,the study group was treated with Bushen Tongmai Prescription.The course of treatment for the two groups covered eight weeks.Before and after treatments,the two groups were observed in the changes of C-reactive protein(CRP),interleukin 1β(IL-1β),interleukin 6(IL-6),vascular cell adhesion molecule 1(VCAM1),miR-126,carotid intima-media thickness(CIMT),carotid plaque Crouse scores,and blood lipid indicators of total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C)and high-density lipoprotein cholesterol(HDL-C).After treatment,the therapeutic efficacy on carotid artery and drug safety in the two groups were evaluated.Results(1)After treatment,the serum miR-126 level in the study group was significantly increased compared with that before treatment(P＜0.01),but the level in the control group only showed a rising trend and the difference was not statistically significant(P＞0.05).The comparison between the two groups showed that the increase of serum miR-126 level in the study group was significantly superior to that in the control group(P＜0.05).(2)After treatment,the serum VCAM1 level in the study group was decreased significantly compared with that before treatment(P＜0.01),but the level in the control group only showed a rising trend and the difference was not statistically significant(P＞0.05).The comparison between the two groups showed that the decrease of serum VCAM1 level in the study group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the serum CRP,IL-1 β,and IL-6 levels in the two groups were decreased compared with those before treatment(P＜0.05 or P＜0.01),and the decrease of serum IL-1β and IL-6 levels in the study group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the TC,TG and LDL-C levels in the study group were decreased(P＜0.01)and the HDL-C level was increased compared with that before treatment(P＜0.01),but in the control group,the changes in the TC,TG,LDL-C,and HDL-C levels were not significant(P＞0.05).The comparison between the two groups showed that the decrease of TC and LDL-C levels in the study group was significantly superior to that in the control group(P＜0.05).(5)After eight weeks of treatment,the total effective rate of the study group was 90.00％(27/30),while that of the control group was 63.33％(19/30).The intergroup comparison(tested by chi-square test)showed that the therapeutic efficacy of the study group was significantly superior to that of the control group(P＜0.05).(6)During the treatment,no serious adverse reactions or toxic-side effects occurred in the two groups.Conclusion Bushen Tongmai Prescription combined with conventional western medicine treatment can up-regulate the level of miR-126,inhibit the expression of VCAM1,and decrease the levels of serum CRP,IL-1β,and IL-6,so as to inhibit inflammatory response and retard the progression of T2DM complicated with ASCVD.The combined therapy exerts certain clinical efficacy and higher safety in treating T2DM complicated with ASCVD.

Objective To explore the association between aspartate aminotransferase(AST)/alanine aminotransferase(ALT)ratio and metabolic syndrome(MS)in elderly hypertensive patients,and to provide reference for early detection and prevention of MS in elderly hypertensive patients.Methods A questionnaire survey and physical examination were conducted among 616 elderly hypertensive patients at community health service centers.Participants were divided into two groups based on MS status:MS group(n=334)and non-MS group(n=282).According to AST/ALT levels,participants were divided into four groups:q1 group(AST/ALT ≤0.88,n=156),q2 group(0.88＜AST/ALT ≤ 1.10,n=155),q3 group(1.10＜AST/ALT ≤ 1.37,n=154),and q4 group(AST/ALT＞1.37,n=151).Blood biochemical parameters including triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),AST,ALT,and blood glucose were measured.The impact of AST/ALT levels on MS was analyzed using a Logistic regression model,while the risk prediction for MS occurrence was evaluated through receiver operating characteristic(ROC)curves.Results MS group showed higher body mass index(BMI),TG,ALT levels,abnormal glucose levels,female proportion,and abdominal obesity rate compared to non-MS group.HDL-C and AST/ALT values of MS group were lower than those in non-MS patients(P＜0.05).Logistic regression analysis revealed that after adjusting for BMI,smoking,alcohol consumption,physical activity,education level,marital status,TG,HDL-C,and glucose levels,both q3 and q4 groups demonstrated reduced MS risk compared to group q1 group(P＜0.05).ROC curve analysis indicated that the area under the curve for AST/ALT in MS was 0.638(P＜0.05).Conclusion The level of AST/ALT was negatively correlated with MS in elderly hypertensive patients,and AST/ALT has certain predictive value for the risk of MS in elderly hypertensive patients.
