Objective:To analyze the clinical features and immunotherapy responsiveness of patients with myelin oligodendrocyte glycoprotein immunoglobulin G-antibody associated disease (MOGAD) with epilepsy, and display the risk factors of epilepsy in MOGAD.Methods:Eighty-nine patients with MOGAD diagnosed at the First Affiliated Hospital of Zhengzhou University between October 2019 and May 2023 were enrolled and classified into 2 groups upon MOGAD with ( n=29) or without epilepsy ( n=60). The Expanded Disability Status Scale (EDSS) and Clinical Assessment Scale for Autoimmune Encephalitis (CASE) were used for evaluation of severity, and EDSS or CASE scores on the 30th day after first-line immunotherapy initiation lower than that on admission were defined as well treatment responsiveness. The differences of general data, clinical manifestations, cerebrospinal fluid (CSF) and peripheral blood biochemical examination results, and immunotherapy reactivity between the 2 groups were thoroughly explicated. In addition, the risk factors of epilepsy in MOGAD were analyzed by univariate and multivariate Logistic regression analysis. Results:Compared with patients with MOGAD without epilepsy, patients with MOGAD with epilepsy were characterized by lower age of onset [24.5(10.3, 34.0) years vs 11.0(6.5, 20.0) years, Z=-2.348, P=0.019], higher percentage of male patients [43.3%(26/60) vs 75.9%(22/29), χ 2=8.326, P=0.004], higher virus infection rate [28.3%(17/60) vs 51.7%(15/29), χ 2=4.645, P=0.031], higher incidence of prodromal symptoms [11.7%(7/60) vs 34.5%(10/29), χ 2=6.586, P=0.010], higher blood-brain barrier breakdown rate [35.0%(21/60) vs 58.6%(17/29), χ 2=4.458, P=0.035], higher percentage of CSF albumin level>450 mg/L [48.3%(29/60) vs 75.9%(22/29), χ 2=6.056, P=0.014] and higher creatine kinase level [45.50(28.50, 69.75) U/L vs 57.50(41.75, 97.25) U/L, Z=-2.349, P=0.019]; more epilepsy [0(0) vs 29/29 (100.0%), χ 2=89.000, P<0.001] and disturbance of consciousness [0(0) vs 6/29(20.7%), χ 2=10.224, P=0.001] as clinical manifestations, and more cerebral cortex lesions [30/60(50.0%) vs 25/29(86.2%), χ 2=10.856, P=0.001] on magnetic resonance imaging. Nevertheless, the patients with MOGAD without epilepsy were featured with more visual impairment [23/60(38.3%) vs 3/29(10.3%), χ 2=7.406, P=0.007], limb weakness [18/60(30.0%) vs 1/29(3.4%), χ 2=8.209, P=0.004], sensory disturbance [15/60(25.0%) vs 0(0), Fisher exact probability test, P=0.002] and more cervical cord lesions [22/60(36.7%) vs 4/29(13.8%), χ 2=4.946, P=0.026] on magnetic resonance imaging. Immunotherapy responsiveness was relatively poor in the MOGAD with epilepsy group [EDSS score lower than that on admission: 15/29(51.7%) vs 46/60(76.7%), χ 2=5.641, P=0.018; CASE score lower than that on admission: 16/29(55.2%) vs 47/60(78.3%), χ 2=5.072, P=0.024] compared with the MOGAD without epilepsy group. Male was the independent risk factor of epilepsy in MOGAD ( OR=7.078, 95% CI 1.709-29.326, P=0.007). Conclusions:Compared with patients with MOGAD without epilepsy, patients with MOGAD with epilepsy reported more male patients, lower age of onset and higher incidence of prodromal symptoms, blood-brain barrier dysfunction rate, virus infection rate, CSF albumin level and creatine kinase level; clinical phenotypes were mainly meningoencephalitis and more cerebral cortex lesions were shown on magnetic resonance imaging. MOGAD with epilepsy was closely related to poor immunotherapy responsiveness, and gender was found to be the independent risk factor for epilepsy in MOGAD.

Objective:To establish a green fluorescent protein(GFP)and firefly luciferase(Luc)double-labeled Epstein-Barr virus(EBV)infec-ted B lymphoblastoid cell lines(B-LCL)and apply them to mouse models,then compare the advantages and disadvantages of models inocu-lated by intravenous(IV)or subcutaneous(SC).Methods:B lymphoblastoid cell lines double-tagged with GFP/Luc(B-LCL-GL)were con-structed through lentivirus transduction,puromycin intervention.Subcutaneous xenograft and hematogenous metastasis models were re-spectively established by subcutaneous or intravenous injection of B-LCL-GL cells at three concentrations in(NOD)/Prkdcscid/IL-2Rγnull(NPG)mice for in vivo bioluminescence imaging.Results:In the B-LCL-GL group,the ratio of the GFP-positive cell population was 92.5%,and the average luminescence intensity was as high as 4.80E+08 Photons/s,which was considerably higher than that of untreated B-LCLs.In the hematogenous metastasis models,tumor bioluminescence was initially located in the peritoneal area and then spread throughout the en-tire body between 7 and 28 days.In the subcutaneous xenograft models,strong central and weak peripheral tumor-related biolumines-cence signal was detected on day 7 in the three groups,which then spread throughout the body on day 28 in the high-dose group.Taken to-gether,there was no significant difference in tumor progression between the two routes of administration when using the same dose of B-LCL-GL cells.However,the survival analysis indicated that the IV injection group,in which all the mice ultimately died,had a shorter time frame for testing than that of the SC injection group,in which the mice survived until day 100 in the low-dose and medium-dose groups,thus allowing for long-term testing.Conclusions:GFP and Luc dual-positive B-LCLs were successfully established to generate hematogenous metastasis and subcutaneous xenograft models,which allow the monitoring of the location and size of lymphomas in vivo.It provide plat-form for the study of tumor characteristics and selecting anti-tumor drugs.

Objective: Comparing the benefit of Abidor, lopinavir/ritonavir and recombinant interferon α-2b triple combination antiviral therapy and lopinavir/ritonavir and interferon dual combination antiviral therapy to hospitalized novel coronavirus pneumonia 2019 in Zhejiang province. Methods: A multi-center prospective study was carried out to compare the effect of triple combination antiviral therapy with dual combination antiviral therapy in 15 medical institutions of Zhejiang Province. All patients were treated with recombinant interferon α-2b (5 million U, 2 times/d) aerosol inhalation. 196 patients were treated with abidol (200 mg, 3 times/d) + lopinavir / ritonavir (2 tablets, 1 time/12 h) as the triple combination antiviral treatment group. 41 patients were treated with lopinavir / ritonavir (2 tablets, 1 time/12 h) as the dual combination antiviral treatment group. The patients who received triple combination antiviral therapy were divided into three groups: within 48 hours, 3-5 days and > 5 days after the symptom onset. To explore the therapeutic effects of triple combination antiviral drugs and dual combination antiviral drugs, as well as triple combination antiviral drugs with different antiviral initiate time. SPSS17.0 software was used to analyze the data. Results: The time of virus nucleic acid turning negative was (12.2 ± 4.7) days in the triple combination antiviral drug group, which was shorter than that in the dual combination antiviral drug group [(15.0 ± 5.0) days] (t = 6.159, P < 0.01 ). The length of hospital stay [12 (9, 17) d] in the triple combination antiviral drug group was also shorter than that in the dual combination antiviral drug group [15 (10, 18) d] (H = 2.073, P < 0.05). Comparing the antiviral treatment which was started within 48 hours, 3-5 days and > 5 days after the symptom onset of triple combination antiviral drug group, the time from the symptom onset to the negative of viral shedding was 13 (10,16.8), 17 (13,22) and 21 (18-24) days respectively (Z = 32.983, P < 0.01), and the time from antiviral therapy to the negative of viral shedding was (11.8±3.9) , (13.5±5.1) and (11.2±4.3) d. The differences among the three groups were statistically significant (Z=32.983 and 6.722, P<0.01 or<0.05). Conclusions The triple combination antiviral therapy of Abidor, Lopinavir/Litonavir and recombinant interferon α-2b showed shorter viral shedding time and hospitalization time compared with the dual combination antiviral therapy. The earlier the time to initiate triple antiviral treatment, the shorter the time of virus shedding.

The clinical data of 2 children with early graft liver dysfunction (EAD) admitted to the Pediatric Intensive Care Unit, Shanghai Children′s Medical Center, Shanghai Jiaotong University School of Medicine were retrospectively analyzed to discussed the therapeutic significance of non-biological artificial liver technology, such as intermittent plasma exchange (PE) combined with continuous veno-venous hemodiafiltration (CVVHDF) in children with EAD.Case 1 was suffering from biliary atresia, and case 2 was suffering from Niemann-Pick disease.Graft liver dysfunction and multiple organ dysfunction occurred in 2 children after liver transplantation.PE and CVVHDF were initiated early in the first two days after liver transplantation.After one-week therapy with intermittent PE plus CVVHDF, acute multiple organ dysfunction were reversed with liver function remarkably improved in the 2 cases.Therefore non-biological artificial liver technique can be tried after liver transplantation in children.This technique contributes to the recovery of liver function and can improve the secondary multi-organ insufficiency.

Objective:To explore the early predictive value of urinary nephrin in acute kidney injury (AKI) for critically ill neonates.Methods:A prospective study was conducted to neonates who were admitted to Neonatal Intensive Care Unit (NICU) Children′s Hospital of Soochow University, from July to October 2016.According to whether AKI occurred during the NICU′s hospitalization, neonates were divided into AKI group and non-AKI group.Urinary nephrin levels were detected at the first 24 h of NICU, and the score for neonatal acute physiology (SNAP) was assessed within 24 hours of NICU.Multivariate linear analyses were applied to analyze potential variables that were asso-ciated with urinary nephrin level.Multivariate Logistic regression analysis was adopted to evaluate the relationship between urinary nephrin and AKI after adjusting for confounding factors.A receiver operating characteristic(ROC) curve and the area under the ROC curve (AUC) were calculated to assess the early predictive value of urinary nephrin for neonatal AKI. Results:Among the 156 neonates enrolled in the study, 16 cases(10.2%) developed AKI.The median of urinary nephrin, urinary albumin and SNAP scores were 0.27 μg/mg uCr, 0.48 g/g uCr and 9 scores with AKI group, while the median of urinary nephrin, urinary albumin and SNAP scores were 0.16 μg/mg uCr, 0.16 g/g uCr and 7 scores with non-AKI group.When compared with non-AKI neonates, urinary nephrin ( Z=-3.201, P=0.001), urinary albumin ( Z=-2.652, P=0.008) and SNAP score ( Z=-2.611, P=0.009) were significantly higher in AKI neonates.Multiple linear regression analysis proved that urinary nephrin levels were significantly correlated with urinary albumin ( B=0.488, SE=0.117, P<0.001). Multivariate Logistic regression analysis revealed that urinary nephrin remained significantly associated with AKI ( P=0.018) after adjusting for confounding factors, including gestational age, birth weight, gender, SNAP score, mechanical ventilation and apnea.Urinary nephrin achieved AUC of 0.746 (95% CI: 0.606-0.886, P=0.001). Conclusions:As a biomarker of glomerular injury, urinary nephrin is significantly related to the occurrence of AKI and has early predictive value for AKI in critically ill neonates.

December 2019 witnessed the outbreak of COVID-19 in Wuhan and spread of the epidemic across the country. As a provincial designated hospital for critical patients, the First Affiliated Hospital of Zhejiang University responded rapidly since then by advocating the four-concentration principles, namely " concentrating patients, experts, resources and treatment" . In its rescue of critical patients, the hospital formulated comprehensive emergency plans, optimized hospital-wide resources, effectively arranged rescue spacing, established medical echelons, and implemented multi-disciplinary strategy. These efforts ensured efficient rescue and treatment, achieving a cure rate up to 98.7% of such patients, with no deaths.

Objective:To compare the efficacy of the combination of abidol, lopinavir/ritonavir plus recombinant interferon α-2b (rIFNα-2b) and the combination of lopinavir/ritonavir plus rIFNα-2b for patients with COVID-19 in Zhejiang province.Methods:A multicenter prospective study was carried out to compare the efficacy of triple combination antiviral therapy and dual combination antiviral therapy in 15 medical institutions of Zhejiang province during January 22 to February 16, 2020. All patients were treated with rIFNα-2b (5 million U, 2 times/d) aerosol inhalation, in addition 196 patients were treated with abidol (200 mg, 3 times/d) + lopinavir/ritonavir (2 tablets, 1 time/12 h) (triple combination group) and 41 patients were treated with lopinavir/ritonavir (2 tablets, 1 time/12 h) (dual combination group). The patients who received triple combination antiviral therapy were further divided into three subgroups: <48 h, 3-5 d and >5 d according the time from the symptom onset to medication starting. The therapeutic efficacy was compared between triple combination group and dual combination group, and compared among 3 subgroups of patients receiving triple combination antiviral therapy. SPSS 17.0 software was used to analyze the data.Results:The virus nucleic acid-negative conversion time in respiratory tract specimens was (12.2±4.7) d in the triple combination group, which was shorter than that in the dual combination group [(15.0±5.0) d] ( t=6.159, P<0.01). The length of hospital stay in the triple combination group [12.0 (9.0, 17.0) d] was also shorter than that in the dual combination group [15.0 (10.0, 18.0) d] ( H=2.073, P<0.05). Compared with the antiviral treatment which was started within after the symptom onset of in the triple combination group, the time from the symptom onset to the viral negative conversion was 13.0 (10.0, 17.0), 17.0 (13.0, 22.0) and 21.0 (18.0, 24.0) d in subgroups of 48 h, 3-5 d and >5 d, respectively ( Z=32.983, P<0.01), while the time from antiviral therapy to viral negative conversion was (11.8±3.9), (13.5±5.1) and (11.2±4.3) d, respectively( Z=6.722, P<0.05). Conclusions:The triple combination antiviral therapy of abidol, lopinavir/litonavir and rIFNα-2b shows shorter viral shedding time and shorter hospitalization time, compared with the dual combination antiviral therapy; and the earlier starting triple combination antiviral therapy will result in better antiviral efficacy.

Objective: To investigate the feasibility and accuracy of transperineal real-time three-dimensional ultrasound combined with clinical factors in predicting the risk of female stress urinary incontinence(SUI). Methods: Three hundred and forty-eight female patients with SUI diagnosed were selected as the case group, and 102 healthy people in the same period were selected as the control group. All subjects underwent transperineal real-time three-dimensional ultrasound. The ultrasonic parameters of resting state, contraction and Valsalva were measured, and the clinical parameters such as age, height, weight, history of pregnancy and childbirth were collected. According to the time sequence, all the subjcets were divided into derivation cohort and verification cohort inproportion to 2∶1, single factor screening and logistic multiple regression analysis were carried out on 24 factors, and the risk model was established. The cut-off value of the disease probability P was determined by the ROC curve of the subjects, and then the accuracy of the cut-off value in predicting SUI was verified in the verification group. Results: Single factor analysis showed that 13 parameters were associated with SUI(all P<0.05). Logit P=2.014+ 1.870×Z₁ was established by multivariate logistic regression analysis. The cut-off value of the disease probability P determined by ROC curve was 0.823. The predictive sensitivity of the model was 68.1% (95%CI: 59.6%-76.6%), specificity was 91.2% (95%CI: 86.0%-96.4%), positive predictive value was 64.3% (95%CI: 55.6%-73.0%) and negative predictive value was 92.5% (95%CI: 86.2%-98.8%). Conclusions It is feasible to predict the risk of female stress urinary incontinence by transperineal real-time three-dimensional ultrasound combined with clinical factors. Although, some limitations with the prediction model, it has accuracy in predicting SUI with obvious symptoms.

The RASopathies are a group of syndromes that have in common germline mutations in genes that encode components of the RAS/mitogen-activated protein kinase (MAPK) pathway and have been a focus of study to understand the role of this pathway in development and disease. These syndromes include Noonan syndrome (NS), NS with multiple lentigines (NSML), neu-rofibromatosis type 1 (NF1), Costello syndrome (CS), cardio-facio-cutaneous (CFC) syndrome, neurofibromatosis type 1-like syndrome (NFLS) and capillary malformation-arteriovenous malformation syndrome (CM-AVM). These disorders affect multiple systems, including the craniofacial complex. Although the crani-ofacial features have been well described and can aid in clinical diagnosis, the dental phenotypes have not been analysed in detail for each of the RASopathies. In this review, we summarize the clinical features of the RASopathies, highlighting the reported craniofacial and dental findings.
