Objective:To evaluate the role of myosin heavy chain 9(MYH9) in gut-vascular barrier damage in septic mice.Methods:Eighty SPF C57BL/6J male mice, aged 6-8 weeks, weighing 20-25 g, were divided into 4 groups( n=20 each) by the random number table method: sham operation group(Sham group), sham operation + MYH9 inhibitor blebbistatin group(Sham+ Ble group), cecal ligation and perforation(CLP) group, and CLP+ blebbistatin group(CLP+ Ble group). A mouse sepsis model was established using CLP in anesthetized animals. Blebbistatin solution 5 mg/kg was intraperitoneally injected at 1 h before CLP in Sham+ Ble and CLP+ Ble groups, while the equal volume of phosphate buffer was given instead in Sham and CLP groups. Fourteen mice were randomly selected from each group to observe the survival at 24 h after CLP. Blood samples were taken by apical puncture at 24 h after surgery in the remaining 6 mice in each group for determination of the plasma concentrations of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β) and interleukin-6(IL-6)(using enzyme-linked immunosorbent assay), expression of plasma membrane vesicle-associated protein(PLVAP) in intestinal microvascular endothelial cells(using immunofluorescence), and expression of MYH9, PLVAP, vascular endothelial calreticulin(VE-cadherin) and β-catenin protein and mRNA(by Western bot or fluorescent quantitative real-time polymerase chain reaction) and for examination of the pathological changes of intestinal tissues.

Objective:To compare and explore the diagnostic performance of adding value of transabdominal and transvaginal contrast-enhanced ultrasound (CEUS) to Ovarian-Adnexal Reporting and Data System (O-RADS US) risk stratification and management system in differential diagnosis of adnexal masses.Methods:A total of 180 adnexal masses with solid components in 175 women were enrolled retrospectively between September 2021 and November 2022. All patients underwent routine Doppler ultrasound examinations and CEUS examinations. Among these masses, 107 masses underwent with transabdominal CEUS, 58 masses underwent with transvaginal CEUS, and 15 masses underwent both transvaginal and transabdominal CEUS. All patients were scheduled for surgery and pathological results served as the reference standard. Routine Doppler ultrasound and CEUS images and video were reviewed by a subspecialty radiologist using Vuebox software. The O-RADS US was downgraded or upgraded according to the CEUS characteristics of the masses. The diagnostic accuracy was assessed using ROC curve analysis. The area under the ROC curve (AUC) was calculated to compare the diagnostic performance of adding value of transabdominal and transvaginal CEUS to O-RADS US.Results:The diagnostic performance of adding transabdominal and transvaginal CEUS to O-RADS US were both significantly higher than of O-RADS US alone (transabdominal CEUS: AUC 0.83 vs 0.76, P=0.018; transvaginal CEUS: AUC 0.92 vs 0.81, P=0.013). Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in the differential diagnosis of adnexal masses ( P=0.047). When the maximal diameter of adnexal masses ≤40 mm, transabdominal combined with O-RADS US presented the lowest diagnostic performance, with an AUC of 0.73. Conclusions:Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in assessing adnexal masses with solid components. When the maximal diameter of adnexal masses ≤40 mm, transvaginal CEUS examination was recommended.

Objective:To construct a novel cuproptosis-related gene signature (CRGS) for prediction of prognosis, immunotherapy response and drug sensitivity in patients with hepatocellular carcinoma (HCC).Methods:Data materials for this study were obtained from the international cancer genome consortium (ICGC), the cancer genome atlas (TCGA) database and Migort210 database, and protein expression profiles were obtained from the human protein atlas image classification database. Based on the TCGA cohort, the least absolute shrinkage and selection operator algorithm was applied to construct the CRGS and calculate the risk score for each HCC patient. HCC patients were grouped according to the median risk score: HCC patients in the TCGA cohort were divided into a high-risk group TCGA and a low-risk group TCGA with 184 cases in each group; HCC patients in the ICGC cohort were divided into a high-risk group ICGC and a low-risk group ICGC with 116 cases in each group. Patients in the Migort210 cohort were divided into a responder group ( n=68) and a non-responder group ( n=230) based on their response to immunotherapy. We assessed the value of CRGS in predicting the prognosis of HCC patients in the TCGA cohort and validated whether CRGS could be used to predict the prognosis of HCC patients in the ICGC dataset. To explore the role of CRGS in predicting immunotherapy response and drug sensitivity in HCC patients based on data from the TCGA cohort, and to apply the Migort210 immunotherapy cohort to validate the clinical value of CRGS in predicting immunotherapy in malignant tumors. Results:CRGS consists of four copper death-related genes: GLS, CDKN2A, LIPT1, and DLAT. Patients in the high-risk group TCGA had lower overall survival (OS), disease-specifical survival, and progression-free interval than those in the low-risk group TCGA (all P<0.01). OS of patients in the high-risk group ICGC was lower than that in the low-risk group ICGC ( P=0.022). Multivariate Cox regression analysis showed that CRGS was an independent risk factor for poor prognosis in HCC patients (TCGA: HR=2.991, 95% CI: 1.781-5.049, P<0.001; ICGC: HR=4.621, 95% CI: 1.685-12.674, P=0.033). Risk scores were positively correlated with the expression levels of CTLA4, PDCD1, CD80 and HLLA2 (all P<0.001). Patients in the high-risk group TCGA had lower tumor immune dysfunction and rejection scores than those in the low-risk group TCGA [-0.04(-0.07, -0.02) vs. -0.02(-0.04, 0) points], and the difference was statistically significant ( P<0.001). Patients in the responder group had a higher risk score than the non-responder group [1.70 (1.56, 1.90) vs. 1.63 (1.52, 1.80)], with a statistically significant difference ( P<0.05). The half-inhibitory concentrations (IC 50) for sunitinib, rapamycin and etanercept were higher in the high-risk group TCGA than that in the low-risk group TCGA, while the IC 50 for erlotinib was lower than that in the low-risk group TCGA, and the differences were all statistically significant (all P<0.001). Conclusion:The CRGS might be served as a potential biomarker to predict the prognoses, immunotherapy response, and drug sensitivity of patients with HCC.

In recent years, more and more researchers at home and abroad have realized that there is a certain relationship between allergic rhinitis(AR) and attention deficit hyperactivity disorder(ADHD) in children.Children with AR had higher ADHD related symptom scores than healthy children; ADHD children have a significantly increased risk of allergic diseases, such as asthma, eczema and atopic dermatitis.At present, it has been clear that they have the common characteristics of increasing prevalence year by year, genetic tendency, environmental and neuropsychological factors, and similar clinical manifestations.However, there is no final conclusion whether they are mutual cause and effect or comorbidities.This artide reviews the similarities between AR and ADHD in epidemiology, etiology, clinical manifestations and drug treatment, so as to further explore the correlation between AR and ADHD.

Objective:To analyze the urodynamic and clinical features of detrusor underactivity(DU)in elderly men aged 60 years and over.Methods:Five hundred and seventy-three men aged 60 years and over underwent urodynamic measurements due to dysuria were retrospectively analyzed.According to the urodynamic parameters of bladder contractibility index(BCI)and bladder outlet obstruction index(BOOI), they were divided into the three groups: only detrusor underactivity(DU group)(BCI<100 and BOOI<20), only bladder outlet obstruction(BOO group)(BCI≥100 and BOOI≥40), and the combined non-DU and non-BOO group(NDB group)(BCI≥100 and BOOI<20). The urodynamic and clinical features were compared between the three groups.Results:The internalized 323 patients meeting inclusion and exclusion criteria were divided into 3 groups: 75 in the DU, 207 in the BOO and 41 in the NDB.The age was higher in DU and BOO groups than in NDB group( P<0.05). The DU group versus the NDB group showed the higher levels or values in the volume at first desire(FDV)[(279±80)ml vs.(238±72)ml], the proportions of incomplete bladder emptying(41% vs.17%), urine flow interruption(39% vs.15%)and retention(26% vs.7%), and the lower levels in the voiding efficiency(VE)[(61±32)% vs.(110±41)%], (all P<0.05). The DU group vs.the BOO group showed the increased levels or values in the FDV[(279±80)ml vs.(206±67)ml]and maximum cytometric capacity(MCC)(353±113 ml vs.281±94 ml)and the proportions of urine flow interruption(39% vs.22%), TURP(26% vs.6%), and retention(26% vs.14%), and the decreased levels or values in the VE[(61±32)% vs.(78±37%)], the proportions of DO(41% vs.77%), urgency(26% vs.43%)and nocturia(23% vs.39%)(all P<0.05). Conclusions:The main urodynamic and clinical features are manifested as the reduction of bladder sensation and bladder emptying rate, urine flow interruption, urinary retention and having a TURP history in elderly man with detrusor underactivity.The proportions of DU and BOO are increased along with aging.
