To investigate the therapeutic effect and related mechanisms of hordenine on ovalbumin (OVA)-induced allergic rhinitis (AR) in rats, HE and AB-PAS staining were used to detect the improvement of pathological damage to the nasal mucosa induced by hordenine. ELISA was employed to detect the effect of hordenine on OVA-sIgE in serum and IL-4 in the nasal mucosa supernatant of rats. IHC and Western blot experiments were undertaken to examine the effect of hordenine on Th1/Th2 cell balance. Bioinformatics analysis was performed to predict pathways, which were verified by in vivo and in vitro experiments. The experimental results showed that hordenine could alleviate the behavioral manifestations of OVA-induced AR rats, alleviate nasal mucosal pathological damage caused by AR, and reduce the secretion of OVA-sIgE and IL-4. In addition, hordenine could regulate the Th1/Th2 balance. Bioinformatics analysis results showed that the potential pathway of action of hordenine on AR was the phosphoinositide 3 kinase (PI3K)/protein kinase B (Akt) signaling pathway. The in vivo experimental results showed that the expression of PI3K and p-Akt proteins in the nasal mucosa of the model group rats was significantly increased (P < 0.01), and that the protein expression level was significantly decreased after the administration of hordenine, which was also confirmed by an in vitro experiment. This study suggests that hordenine may regulate Th1/Th2 cell balance through the PI3K/Akt signaling pathway, thereby exerting an alleviating effect on OVA-induced AR.

ObjectiveTo develop a classification model based on complete blood count （CBC） parameters combined with clinical factors to predict severe respiratory infections caused by Human adenovirus （HAdV） in pediatric patients. MethodsFrom September 2023 to September 2024， the CBC parameters and related clinical data from pediatric patients diagnosed with HAdV infection were collected. Principal component analysis and random forest models were used to identify potential predictors of severe cases. ResultsA total of 668 pediatric patients were included， with 564 cases assigned to the training cohort and 104 cases to the validation cohort. Severe cases were defined as pneumonia and/or fever lasting ≥5 days （pneumonia or prolonged fever， PorPF）. Principal component analysis and feature importance analysis （Mean Decrease Gini value） identified the monocytosis ratio （PMono）， red blood cell count （RBC）， and platelet count （PLT） as the most critical CBC parameters. Logistic regression analysis revealed that oxygen therapy （OR = 4.367， 95% CI： 1.568–12.161） and increased work of breathing （OR = 3.904， 95% CI： 2.146–7.101） were relative risk factors for PorPF. Meanwhile， higher PMono （OR = 0.696， 95% CI： 0.640–0.757）， RBC （OR = 0.201， 95% CI： 0.124–0.325）， and PLT （OR = 0.990， 95% CI： 0.987–0.994） were protective factors. When PMono was used as a predictive marker for PorPF， the area under the receiver operating characteristic curve （AUC） was 0.648 and 0.705， respectively. A random forest model incorporating four risk factors ［PMono， RBC， PLT， and hematocrit （HCT）］ was constructed to classify PorPF and general cases， achieving AUCs of 0.688 and 0.768， respectively. ConclusionsPMono， RBC， and PLT may serve as characteristic CBC indicators for predicting pneumonia or prolonged fever in children with HAdV infection. A risk factor model built using PMono， RBC， PLT， and HCT offers a relatively simple and accurate approach to predicting severe cases in pediatric HAdV infections.

Objective To compare the clinical efficacy between liposuction combined with circumareolar small incision and three-port endoscopic surgery for the treatment of Simon Ⅱ gynecomastia (GYN). Methods Comparative case data of 120 patients with GYN were retrospectively analyzed, 61 patients in the open group underwent circumareolar small incision mastectomy after liposuction, and 59 patients in the endoscopic group underwent three-port endoscopic mastectomy after liposuction. The two groups were compared in terms of surgery-related indexes, occurrence of postoperative complications and patient satisfaction. Results The unilateral operation time of the open group was shorter than that of the endoscopic group, the unilateral gland resection weight in the open group was more than that in the endoscopic group, the hospitalization cost of the open group was less than that of the endoscopic group (all P<0.01). There was no significant difference in unilateral liposuction volume, drainage volume on the first postoperative day, and time to drain removal between the two groups (P>0.05). The incidence of complications in the open group and the endoscopic group were 8.2% and 13.6% respectively, and there was no significant difference between the two groups (P>0.05). The difference in the overall satisfaction scores between the two groups was not statistically significant (P>0.05). Conclusions Liposuction combined with circumareolar small incision or three-port endoscopic surgery both has good cosmetic effects in the treatment of Simon Ⅱ GYN. The operation with circumareolar small incision is simple, has a shorter operation time, costs less, and does not require special equipment, which is suitable for promotion and application in medical institutions.

Objective To investigate the predictive value of serum circular RNA(circRNA)CDYL and circRNA ACAP2 expression levels for major adverse cardiovascular events(MACE)in pa-tients with acute myocardial infarction(AMI).Methods A total of 98 AMI patients were enrolled into the observation group,and divided into MACE group(n=45)and no-MACE group(n=53)based on whether they experienced MACE.Another 98 healthy individuals who underwent physical ex-amination during the same period were selected as the control group.The expression levels of serum cir-cRNA CDYL and circRNA ACAP2 were compared among groups.Multivariate logistic regression analysis was used to identify factors influencing the occurrence of MACE in AMI patients.Receiver operating characteristic(ROC)curve analysis was conducted to evaluate the predictive value of serum circRNA CDYL and circRNA ACAP2 levels for MACE in AMI patients.Results The serum circRNA CDYL level in the observation group was significantly lower than that in the control group,while the circRNA ACAP2 level was significantly higher(P＜0.05).The circRNA CDYL level in the MACE group was significantly lower,and the circRNA ACAP2 level was significantly higher than that in the no-MACE group(P＜0.05).Heart rate and circRNA ACAP2 were identified as independent risk factors for MACE in AMI patients,whereas circRNA CDYL served as independent protective factor(P＜0.05).The area under the ROC curve(AUC)for predicting MACE in AMI patients using se-rum circRNA CDYL,circRNA ACAP2 and their combination were 0.814,0.821 and 0.921,re-spectively.The sensitivity and specificity of combined prediction using serum circRNA CDYL and circRNA ACAP2 were 91.11％and 79.25％,respectively.The combined prediction efficacy of serum circRNA CDYL and circRNA ACAP2 was superior to their individual prediction(Zcombined-circRNA CDYL=1.975,Zcombined-circRNAACAP2=2.064,P=0.048,0.039).Conclusion Serum circRNA CDYL lev-el is down-regulated and circRNA ACAP2 level is up-regulated in AMI patients,and circRNA ACAP2 is an independent risk factor for MACE,while circRNA CDYL is a independent protective factor.The combined value of circRNA CDYL and circRNA ACAP2 in predicting the occurrence of MACE is higher.

Background::Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) can profoundly affect the mental health of the people living with HIV (PLWH), with higher rates of anxiety, depression, and sleep disturbances. The disparities in neuropsychological problems evaluated by physicians and self-assessed by patients are still unknown.Methods::A total of 5000 PLWH and 500 physicians from 167 hospitals were enrolled in this cross-sectional study from September 2022 to February 2023. 4-Item Patient Health Questionnaire (PHQ-4) was used for the evaluation of depressive issues and anxiety issues by PLWH. Each physician assessed 10 PLWH under their care for the presence of depressive or anxiety issues. The primary outcomes of this study are the concordance rates on the depressive issues and anxiety issues evaluation between physicians and PLWH. The Cohen’s kappa test was used to assess the agreement between physicians and PLWH.Results::The concordance rate for the evaluation of depressive issues is 73.84% (95% confidence interval [CI]: 72.60-75.04%), and it is significantly different from the expected rate of 80% ( P <0.001). Similarly, the concordance rate for the evaluation of anxiety issues is 71.74% (95% CI: 70.47-72.97%), which is significantly different from the expected rate of 80% as per the null hypothesis ( P <0.001). The overestimation rate by physicians on depressive issues is 12.20% (95% CI: 11.32-13.14%), and for anxiety issues is 12.76% (95% CI: 11.86-13.71%). The mismatch rate for depressive issues is 26.16% (95% CI: 24.96-27.40%), and for anxiety issues is 28.26% (95% CI: 27.02-29.53%). The underestimation rate by physicians on depressive issues is 13.96% (95% CI: 13.03-14.95%), and for anxiety issues is 15.50% (95% CI: 14.52-16.53%). For the treatment regiments, PLWH sustained on innovative treatment regimen (IR) related to a lower prevalence of depressive issues (odds ratio [OR] = 0.71, 95% CI: 0.59-0.87, P = 0.003) and a lower prevalence of anxiety issues (OR = 0.63, 95% CI: 0.52-0.76, P <0.001). PLWH switch from conventional treatment regimen (CR) to IR also related to a lower prevalence of depressive issues (OR = 0.79, 95% CI: 0.64-0.98) and a lower prevalence of anxiety issues (OR = 0.81, 95% CI: 0.67-0.99). Conclusion::Nearly one in three PLWH had their condition misjudged by their physicians. The findings underscore the need for improved communication and standardized assessment protocols in the care of PLWH, especially during the acute phase of HIV infection.

Objective:To analyze the disease burden in middle-aged and elderly population aged ≥55 in Shenzhen from 2016 to 2030 and provide evidence for the development of healthy aging strategies.Methods:The years of life lost (YLL), years lost due to disability (YLD), and the disability-adjusted life year (DALY) in this population from 2016 to 2022 were calculated. Joinpoint log-linear regression model was used to analyze the time trend. Bayesian age-period-cohort model and grey system model were used to predict YLL, YLD, and DALY in this population in 2030.Results:From 2016 to 2022, the crude DALY rate showed a transient fluctuation in age group 55-74 years, but a pronounced increase in age group ≥85 years. The proportions of YLL and YLD due to non-communicable diseases in all age groups was considerably higher than those due to communicable and nutritional diseases and injuries. In 2022, in all age groups, the YLL due to neoplasms (55-74 years old) and cardiovascular disease (≥75 years old) ranked first, and the YLD due to musculoskeletal disorder ranked first. By 2030, the causes of YLL and YLD ranking first in each age group would be remained, while the ranks of some causes would increase.Conclusions:The age specific characteristics of current and predicted disease burden differed in individuals aged ≥55 years. Therefore, it is necessary to allocate social and medical resources according to the disease burden pattern.

Objective To compare the safety and efficacy of direct thrombectomy versus bridging thrombectomy in the treatment of acute anterior circulation large vessel occlusion stroke under different collateral circulation statuses.Methods Totally 93 patients with acute anterior circulation ischemic stroke admitted to the First Affiliated Hospital of Xinxiang Medical University from September 2020 to March 2023 were selected as the research subjects.Patients were divided into direct throm-bectomy group(n=47)and bridging thrombectomy group(n=46)based on the type of thrombectomy.Patients in the direct thrombectomy group received direct intravascular thrombectomy,while patients in the bridging thrombectomy group received intravenous thrombolysis with alteplase combined with mechanical thrombectomy.According computed tomography angiography,the collateral circulation Tan classification was applied to divide the patients into good collateral circulation sub-group and poor collateral circulation sub-group.The modified thrombolysis in cerebral infarction grading(mTICI)was used to evaluate vessel recanalization.Head computed tomography plain scan was performed at 24-48 hours postoperatively to assess if there was hemorrhagic transformation,and modified Rankin Scale score was performed at 90 days postoperatively.Information such as imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,prognosis and spontaneous non-traumatic symptomatic intracerebral hemorrhage(SICH)were collected.Results The age,gender,baseline Alberta stroke program early computed tomography score,baseline national institutes of health stroke scale score,proportions of hypertension,diabetes and atrial fibrillation,baseline systolic pressure,creatinine,baseline blood glucose,platelet count,occlusion site,stroke etiologies and collateral circulation status of patients in the two groups were not statistically significantly different(P＞0.05).There were no significant differences in the post-admission imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,successful vascular reperfusion rate,good prognosis rate,mortality rate,and SICH incidence between the two groups(P＞0.05).The hemorrhagic transformation rate of patients in the direct thrombectomy group was significantly lower than that in the bridging thrombectomy group(P＜0.05).There were no significant differences in the post-admission imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,successful vascular reperfusion rate,good prognosis rate,mortality rate,and SICH incidence between patients with good collateral circulation and patients with poor collateral circulation in the two groups(P＞0.05).The hemorrhagic transformation rate of patients with good and poor collateral circulation in the direct thrombectomy group was significantly lower than that in the bridging thrombectomy group(P＜0.05).Conclusion Under different collateral circulation conditions,the safety and efficacy of direct thrombectomy and bridging thrombectomy in the treatment of acute anterior circulation large vessel occlusion stroke are similar,but bridging thrombectomy is more likely to result in cerebral hemorrhage transformation compared with direct thrombectomy.
