ABSTRACT
Objective:To analyze the epidemiological features of respiratory syncytial virus (RSV) infection in Beijing, and monitor the sequence variations in RSV glycoprotein (G) gene and clinical features of infected children.Methods:Respiratory tract specimens were collected from children with acute respiratory infection in the Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 1, 2023 to December 31, 2023. RSV-positive specimens screened by multiple nucleic acid testing were subjected to PCR to amplify the full-length RSV G gene. A phylogenetic tree was constructed after gene sequencing to analyze RSV subtypes and trace G gene variants. Clinical data were retrieved from the medical record system to analyze the clinical features of children with RSV infection in Beijing.Results:A total of 5 489 respiratory specimens were collected from 3 046 male patients and 2 443 female patients. The average age of the patients was 4.36 years. A total of 589 RSV-positive specimens (10.7%, 589/5 489) were detected with 349 from male patients and 240 from female patients. The average age of children with RSV infection was (2.51±2.78) years and the median age was 0.48 years. RSV had been circulating among children in Beijing since March 2023 with two epidemic peaks in May (24.6%, 122/496) and December (18.2%, 126/693). The predominant subtype of RSV in the first half of 2023 was subtype A, but it was replaced by subtype B from November 2023. Phylogenetic analysis revealed a novel G gene of RSV subtype B (RSV-B-BA9-954bp) with a length of 954 bp, which belonged to a new cluster in the phylogenetic tree. The percentage of patients admitted to the Intensive Care Unit (ICU) was higher in children with new variant of RSV subtype B infection than in those with common RSV subtype B infection [44.1% (15/34) vs 25.2% (31/123), χ 2=4.600, P=0.032], while the counts of white blood cells and the levels of C-reactive protein were lower in the children with new variant infection ( P<0.05). Conclusions:RSV has been prevalent among children in Beijing since March 2023 with two epidemic peaks. The predominant A subtype is gradually replaced by to B subtype. A new variant of RSV B G gene (RSV-B-BA9-954bp) is detected among the children.
ABSTRACT
Objective:To analyze the clinical and epidemiological characteristics of adult carotid body tumors (CBTs) in Northwest China to provide references for early diagnosis and treatment of CBTs.Methods:A multicenter, retrospective, non-intervention epidemiological investigation was conducted on adult CBTs patients who were hospitalized from January 1, 2011 to June 30, 2023 in 7 Class A tertiary hospitals in Northwest China (Departments of Neurosurgery, First Affiliated Hospital of Air Force Medical University, Second Affiliated Hospital of Lanzhou University, People's Hospital of Gansu Province, 940 th Hospital of PLA Joint Logistic Support Force, People's Hospital of Qinghai Province, General Hospital of Ningxia Medical University, People's Hospital of Ningxia Hui Autonomous Region). Medical records were collected in these patients, and they were divided into 2 groups according to their average altitude residence: high altitude group (≥1 500 m) and low altitude group (<1 500 m); meanwhile, these patients were divided into Shamblin type I, type II and type III groups according to Shamblin classification criteria; differences in general data and clinical features among patients from different altitude groups or Shamblin subgroups were compared. Independent influencing factors for Shamblin type III CBTs were analyzed by multivariate ordered Logistic regression. Results:(1) A total of 359 patients were enrolled in the study, including 276 females and 83 males, aged (48.80±12.07) years; 211 patients were into the high altitude group and 148 into the low altitude group; 165 patients were into Shamblin type I group, 146 into Shamblin type II group, and 48 into Shamblin type III group. (2) Compared with those in the low altitude group, patients in the high altitude group had higher proportion of females, older age, lower proportion of Han nationality, higher proportion of Shamblin type I, smaller tumor volume, lower platelet count, higher red blood cell count, hematocrit, hemoglobin level, platelet distribution width and mean platelet volume, and higher large platelet percentage, with significant differences ( P<0.05). (3) Compared with those in the Shamblin type I group, patients in the Shamblin type III group had younger age, lower resident altitude, larger tumor volume, longer time interval from onset to diagnosis, higher proportion of unintentional tumor discovery, larger volume of intraoperative blood loss, lower hemoglobin level, hematocrit, mean erythrocyte volume, and mean hemoglobin concentration, decreased erythrocyte distribution width variable coefficient, and increased platelet count, with significant differences ( P<0.05). Compared with those in the Shamblin type II group, patients in Shamblin type III group had younger age, larger tumor volume, longer time interval from onset to diagnosis, larger volume of intraoperative blood loss, lower hemoglobin, hematocrit and mean erythrocyte volume, higher erythrocyte distribution width variable coefficient and platelet count, with significant differences ( P<0.05). (4) Age ( OR=0.960, 95% CI: 0.942-0.977, P<0.001), residence altitude ( OR=0.992, 95% CI: 0.990-0.999, P=0.020) and time interval from onset to diagnosis ( OR=1.009, 95% CI: 1.005-1.014, P<0.001) were independent influencing factors for Shamblin type III CBTs. Conclusions:More females than males are noted in patients with adult CBTs in Northwest China, and more CBTs patients live at high altitude, with Shamblin type I enjoying the highest proportion. More female and old patients lived at high altitude is noted than those lived at low altitude; patients with Shamblin type III have the youngest age, lowest altitude, and longest time interval from onset to diagnosis. CBTs patients with young age, low residence altitude, and long time interval from onset to diagnosis are more likely to develop Shamblin type III.
ABSTRACT
Herpes zoster is an infectious skin disease caused by reactivation of the varicella-zoster virus with multiple manifestations and various complication clinically. Studies have confirmed that chronic diseases are one of the independent risk factors for HZ; and the common chronic diseases such as diabetes, cardiovascular disease, chronic obstructive pulmonary disease and rheumatoid arthritis are associated with the development of herpes zoster. In this article, we review the latest research progress on the clinical features of herpes zoster, its correlation with common chronic diseases and the prevention strategies to reduce the disease burden.
ABSTRACT
ObjectiveTo explore the clinical features and causative genes of short stature children with unknown etiology， providing evidence for precise clinical diagnosis and treatment. MethodsThe study recruited children with suspected but undiagnosed short stature from the pediatric endocrinology department in our hospital between January 2018 and August 2022. A retrospective analysis was performed on the clinical manifestations， laboratory test and whole exome sequencing （WES） results. Causative genes were classified and analyzed according to different pathogenic mechanisms. ResultsA total of 48 children （30 boys and 18 girls） were enrolled， aged 7.73 ± 3.97 years， with a height standard deviation score （ HtSDS） of -3.63 ± 1.67. Of the patients， 33 （68.8%） suffered from facial anomalies， 31 （64.6%） from skeletal abnormalities， 26 ［54.2%， 61.5% of whom born small for gestational age （SGA）］ from perinatal abnormalities， 24 ［50.0%， 87.5% of whom with growth hormone （GH） peak concentration below normal］ from endocrine disorders and 21（43.8%） had a family history of short stature. Laboratory tests showed that GH peak concentration following stimulation test was （9.72 ± 7.25） ng/mL， IGF-1 standard deviation score was -0.82 ± 1.42， the difference between bone age and chronological age was -0.93 ± 1.39 years. Of the 25 cases with mutant genes found by WES， 14 （56.0%） had pathogenic mutation， 6 （24.0%） likely pathogenic mutation， and 5 （20.0%） mutation of uncertain significance. Pathogenic and likely pathogenic variants were identified in 14 genes， including 10 affecting intracellular signaling pathways （PTPN11， RAF1， RIT1， ARID1B， ANKRD11， CSNK2A1， SRCAP， CUL7， SMAD4 and FAM111A） and 4 affecting extracellular matrix （ECM） components or functions （ACAN， FBN1， COL10A1 and COMP）. ConclusionsA rare monogenic disease should be considered as the possible etiology for children with severe short stature accompanied by facial anomalies， disproportionate body types， skeletal abnormalities， SGA， GH peak concentration below normal and a family history of short stature. WES played an important role in identifying the monogenic causes of short stature. This study indicated that affecting growth plate cartilage formation through intracellular signaling pathways and ECM components or functions was the main mechanism of causative genes leading to severe short stature in children. Further research may help discover and study new pathogenic variants and gene functions.
ABSTRACT
OBJECTIVES@#To study the clinical features of children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection.@*METHODS@#A retrospective analysis was performed on the medical data of 201 children with coronavirus disease 2019 (COVID-19) who were hospitalized and diagnosed with SARS-CoV-2 Omicron variant infection in Quanzhou First Hospital from March 14 to April 7, 2022. Among the 201 children, there were 34 children with asymptomatic infection and 167 with symptomatic infection. The two groups were compared in terms of clinical features, results of experimental examinations, and outcome.@*RESULTS@#Of all the 201 children, 161 (80.1%) had a history of exposure to COVID-19 patients and 132 (65.7%) had a history of COVID-19 vaccination. Among the 167 children with symptomatic infections, 151 had mild COVID-19 and 16 had common COVID-19, with no severe infection or death. Among the 101 children who underwent chest CT examination, 16 had ground glass changes and 20 had nodular or linear opacities. The mean time to nucleic acid clearance was (14±4) days for the 201 children with Omicron variant infection, and the symptomatic infection group had a significantly longer time than the asymptomatic infection group [(15±4) days vs (11±4) days, P<0.05]. The group vaccinated with one or two doses of COVID-19 vaccine had a significantly higher positive rate of IgG than the group without vaccination (P<0.05). The proportions of children with increased blood lymphocyte count in the symptomatic infection group was significantly lower than that in the asymptomatic infection group (P<0.05). Compared with the asymptomatic infection group, the symptomatic infection group had significantly higher proportions of children with increased interleukin-6, increased fibrinogen, and increased D-dimer (P<0.05).@*CONCLUSIONS@#Most of the children with Omicron variant infection have clinical symptoms, which are generally mild. The children with symptomatic infection are often accompanied by decreased or normal blood lymphocyte count and increased levels of interleukin-6, fibrinogen, and D-dimer, with a relatively long time to nucleic acid clearance. Some of them had ground glass changes on chest CT.

Objective:To analyze the epidemic characteristics and clinical key indicators of the patients infected with SARS-CoV-2 of the local Omicron variant epidemic, to understand the clinical characteristics of mild and severe patients, and to provide a scientific basis for the effective treatment and prevention of severe disease.Methods:From January 2020 to March 2022, the clinical and laboratory data of COVID-19 patients admitted to the Fifth People's Hospital of Wuxi were retrospective analyzed, including virus gene subtypes, demographic information, clinical classification, main clinical symptoms, and key indicators of clinical testing, and the changes of clinical characteristics of the patients infected with SARS-CoV-2.Results:A total of 150 patients with SARS-CoV-2 infection were admitted, 78, 52 and 20 in 2020, 2021 and 2022, including 10, 1 and 1 severe patient, and the main infected virus strains were L, Delta, and Omicron variants. The relapse rate of patients infected with the Omicron variant was as high as 15.0% (3/20), the incidence of diarrhea decreased to 10.0% (2/20), the incidence of severe disease decreased to 5.0% (1/20), and the number of hospitalization days of mild patients increased compared with 2020 (days: 20.43±1.78 vs. 15.84±1.12); respiratory symptoms were reduced, and the proportion of pulmonary lesions decreased to 10.5%; the virus titer of severely ill patients with SARS-CoV-2 Omicron variant infection (day 3) was higher than that of L-type strain (Ct value: 23.92±1.16 vs. 28.19±1.54). The acute plasma cytokines interleukin (IL-6, IL-10) and tumor necrosis factor-α (TNF-α) were significantly lower in patients with severe Omicron variant new coronavirus infection than those with mild disease [IL-6 (ng/L): 3.92±0.24 vs. 6.02±0.41, IL-10 (ng/L): 0.58±0.01 vs. 4.43±0.32, TNF-α (ng/L): 1.73±0.02 vs. 6.91±1.25, all P < 0.05], while γ-interferon (IFN-γ) and IL-17A were significantly higher than patients with mild disease [IFN-γ (ng/L): 23.07±0.17 vs. 13.52±2.34, IL-17A (ng/L): 35.58±0.08 vs. 26.39±1.37, both P < 0.05]. Compared with previous epidemics (2020 and 2021), the proportion of CD4/CD8 ratio, lymphocyte count, eosinophil and serum creatinine decreased in patients with mild Omicron infection in 2022 (36.8% vs. 22.1%, 9.8%; 36.8% vs. 23.5%, 7.8%; 42.1% vs. 41.2%, 15.7%; 42.1% vs. 19.1%, 9.8%), the proportion of patients with elevated monocyte count and procalcitonin was large (42.1% vs. 50.0%, 23.5%; 21.1% vs. 5.9%, 0). Conclusion:The incidences of severe disease in patients with SARS-CoV-2 Omicron variant infection was significantly lower than that of previous epidemics, and the occurrence of severe diseases was still related to the underlying diseases.
ABSTRACT
Objective:To investigate the clinical features, treatment options and prognostic factors of extramedullary plasmacytoma of the head and neck.Methods:Clinical data of 31 cases of extramedullary plasmacytoma of the head and neck treated in Eye Ear Nose and Throat Hospital of Fudan University from January 2005 to January 2020 were retrospectively analyzed. According to the involvement sites, the lesions were divided into the Waldeyer's ring involvement and non-involvement groups. The differences between two groups were compared by one-way ANOVA. The overall survival (OS) was analyzed by Kaplan-Meier method. The OS rate and local recurrence free survival (LRFS) rate between two groups were compared by log-rank test.Results:All 31 patients received radiotherapy. The median follow-up time was 98 months (7-192 months). Among them, 16 patients received radiotherapy and surgery, 10 patients received radiochemotherapy, and 2 patients received surgery and radiochemotherapy. Waldeyer's ring involvement was found in 15 patients, and Waldeyer's ring was not involved in 16 patients. The 10-year OS rate was 84.8%. Two cases showed local recurrence and 2 cases progressed to multiple myeloma. The 10-year OS rate in patients ≤55 years old was 100% vs. 67% in those >55 years old ( P=0.039). The 10-year OS rates in patients with and without Waldeyer's ring involvement were 93.3% vs. 75.2% ( P=0.031). The 10-year LRFS rate in patients with Waldeyer's ring involvement was 100% vs. 66.7% in those without Waldeyer's ring involvement ( P=0.022). The 10-year OS rate was 95% and 35.7% for patients with longest diameter of tumor ≤5 cm and >5 cm before radiotherapy, respectively ( P=0.02). Conclusions:Extramedullary plasmacytoma of the head and neck patients with longest diameter of tumor ≤5 cm obtain higher 10-year OS rate. Those with Waldeyer's ring involvement have better 10-year OS and LRFS rates.
ABSTRACT
Epilepsy is a chronic neurological disease and a common disease in neurology.The epidemiologic characters,clinical characteristics and risk factors of epilepsy vary from region to region.Although there are relatively few studies on epilepsy in the plateau,current studies show that its morbidity and prevalence are higher than those in other regions.There is a large gap in epilepsy treatment in the plateau area,and the quality of life of patients is poor.Among them,cerebrovascular diseases,cerebral parasitic diseases and craniocerebral trauma are common causes of epilepsy in the plateau area.This paper summarizes the epidemiologic characteristics,clinical characteristics,risk factors,etiology,comorbidities and other related studies of epilepsy in plateau areas,aiming to offer valuable reference for the diagnosis and treatment of epilepsy patients in plateau areas.
ABSTRACT
@#Objective To investigate the risk factors for fatigue impairment in patients with multiple system atrophy （MSA）. Methods A total of 101 patients with MSA were enrolled，and according to the score of Fatigue Severity Scale （FSS），they were divided into non-fatigue group （<4 points） with 41 patients and fatigue group （≥4 points） with 60 patients. A binary logistic regression analysis was used to screen for the risk factors for fatigue in patients with MSA. Results There were significant differences in sex，course of disease，clinical classification，urinary retention，UMSARS-I，UMSARS-II，UMSARS-I+II，UMSARS-IV，bradykinesia，myotonia，ataxia，abnormal gait and posture，and ESS score between the patients with different between fatigue levels （P<0.05）. The binary logistic regression analysis showed that UMSARS-I and ESS scores were independent risk factors for fatigue in MSA patients （P<0.05）. Conclusion Fatigue impairment in patients with MSA is caused by multiple factors，among which UMSARS-I and ESS scores are independent risk factors for fatigue in MSA.
ABSTRACT
@#Objective To analyze the clinical features of patients with hepatolenticular degeneration （HLD） complicated by hepatic myelopathy （HM）. Methods A retrospective analysis was performed on the clinical features，auxiliary examinations，diagnosis and treatment，and outcomes of 5 patients diagnosed with HLD complicated by HM in our hospital from January 2018 to February 2023，and the relevant literature was reviewed. Results Among the 5 patients，4 were male and 1 was female； the age of onset of HM ranged from 16 to 32 years. All 5 patients had manifestations of decompensated cirrhosis，and 3 patients had a history of transjugular intrahepatic portosystemic shunt （TIPS）. The spinal MRI showed abnormal signals in the thoracic cord in 2 patients. Electromyography showed abnormalities in 3 patients，and electroencephalography showed significantly slower background brain waves in 4 patients. Two patients underwent liver transplantation，and 2 patients received endovascular treatment. One patient died of upper gastrointestinal bleeding； the other 4 patients had varying degrees of recovery. Conclusion The prevalence of HLD complicated by HM is very low. High copper status，hyperammonemia，TIPS，anemia，hypoproteinemia，and portal hypertension are directly associated with HM.
ABSTRACT
Objective:To investigate the clinical features of patients with epilepsy in Neurosurgery Outpatient and influencing factors for their seizure control.Methods:Six hundred and seventy-three epilepsy patients admitted to Neurosurgery Outpatient of 6 hospitals including Fifth Affiliated Hospital of Zhengzhou University from September 2017 to December 2022 were chosen. Clinical data (including general demographic data, education level, onset age, onset cycle and duration, course of onset, family annual income and seizure control) were collected using a questionnaire prepared by He'nan Epilepsy Systematic Diagnosis and Treatment Center to summarize the clinical features. Univariate and multivariate Logistic regressions were used to analyze the influencing factors for their seizure control.Results:(1) In these 673 epilepsy patients, 50 (7.4%), 78 (11.6%), 192 (28.5%), 100 (14.9%), 68 (10.1%), 72 (10.7%) and 113 (16.8%), respectively, were <1 year old (infant stage), 1-2 years old (children stage), 3-5 years old (preschool stage), 6-16 years old (juvenile stage), 17-39 years old (young stage), 40-64 years old (middle-aged stage) and ≥65 years old (elderly stage). In the past medical treatment history, 23.0% (155/673) patients did not receive intervention, 72.4% (487/673) received medication, and 4.6% (31/673) received surgical treatment; 55.9% (376/673) had good seizure control and 44.1% (297/673) had poor seizure control. (2) Secondary education ( OR=2.199, 95% CI: 1.037-15.221, P=0.033), primary education or below ( OR=3.544, 95% CI: 2.101-21.343, P=0.012), daily seizures ( OR=4.788, 95% CI: 1.369-33.103, P=0.011), each seizure lasted ≥3 min ( OR=4.179, 95% CI: 3.338-18.550, P=0.003), course of disease≥3 years ( OR=0.199, 95% CI: 0.077-0.602, P=0.001), course of disease for 1-3 years ( OR=0.379, 95% CI: 0.108-0.882, P=0.031), and currently taken antiepileptic drugs for 3 or more ( OR=6.237, 95% CI: 2.195-17.837, P=0.001) were independent risk factors for poor seizure control in epilepsy patients. Conclusion:In Neurosurgery Outpatient, children with diseases before childhood enjoy the largest proportion; drug therapy remains the main treatment; low education level, short seizure cycle, long duration of attack, long course of disease, and multiple drugs used in these patients imply poor anti-epileptic effecacy.
ABSTRACT
Objective:To study the clinical features of transthyretin amyloid polyneuropathy (ATTR-PN) caused by Ser77Tyr mutation.Methods:The clinical data of a patient with ATTR-PN caused by Ser77Tyr mutation, admitted to our hospital from Department of Neurology, Mindong Hospital Affiliated to Fujian Medical University, were retrospectively analyzed. Literature on patients with ATTR-PN caused by Ser77Tyr mutation in Pubmed, Web of Science, CNKI and Wanfang databases and those with ATTR-PN caused by Val30Met mutation in Pubmed and Web of Science were searched and screened, and clinical characteristics of these patients were extracted. The differences of clinical characteristics among patients with ATTR-PN caused by Ser77Tyr or Val30Met mutations were compared.Results:(1) Transthyroxin ( TTR) gene Sanger sequencing results showed Ser77Tyr heterozygous pathogenic mutation; Congo red staining of biopsy sample in the patient 2.5 years after onset showed amyloid deposition. (2) Seventy-eight patients with ATTR-PN caused by Ser77Tyr mutation were summarized, they mostly had onset at 50-60 years old; male patients had higher incidence (74.4%); most patients (78.0%) had positive family history; most patients had sensory symptoms as initial symptom (72.0%), which gradually progressed to extensive peripheral nerve involvement and combined with widespread heart damage (96.4%) over several years; electrophysiological examination mainly showed axonal damage and carpal tunnel syndrome; the tissue biopsy had high positive rate(84.8%). (3) There were 192 and 96 patients with ATTR-PN caused by early-onset and late-onset Val30Met mutations, respectively; compared with patients with ATTR-PN caused by early-onset Val30Met mutation, patients with ATTR-PN caused by Ser77Tyr mutation had significantly higher incidence of deep sensory disturbance (28.6% vs. 58.5%, P<0.05). Compared with patients with ATTR-PN caused by late-onset Val30Met mutation, patients with ATTR-PN caused by Ser77Tyr mutation had increased incidence of mild sensory disturbance (56.3% vs. 75.0%) and decreased incidence of limb weakness (65.6% vs. 48.3%), with significant differences ( P<0.05). ATTR-PN patients caused by Ser77Tyr mutation had significantly higher incidence of carpal tunnel syndrome than ATTR-PN patients caused by early-onset and late-onset Val30Met mutations (75.4% vs. 10.8% and 25.0%) and significantly higher incidence of cardiac damage than ATTR-PN patients caused by early-onset Val30Met mutation (96.4% vs. 80.5%, P<0.05). Conclusion:Ser77Tyr mutation has some distinctive clinical features: relatively balanced damage of large and small fibers, prominent carpal tunnel syndrome, and obvious heart disease; early identification of these features and administration of tissue biopsy and gene detection are helpful for early diagnosis.
ABSTRACT
Objective To evaluate the predictive value of a combined model based on clinical and radiomics features for the invasiveness of lung adenocarcinoma manifesting as ground glass nodule(GGN).Methods Clinical data of patients with GGN-type lung adenocarcinoma who underwent chest CT and were confirmed by surgical pathology at some hospital from January to December 2019 were analyzed retrospectively,and the extraction of imaging histological features was performed using Python-based open resource Pyradiomics.A clinical model was constructed based on independent risk factors obtained from univariate and multivariate analyses,a radiomics model was built using the screened radiomics features,and a combined model was established with the predictive values of the clinical models and radiomics scores(Radscore).The predictive performance of the three models in the training and test sets was assessed using ROC curves,the statistical significance of the differences in the ROC curves of the three models for predicting GGN-type lung adenocarcinoma was assessed using the Delong test,and the net benefits of the models were analyzed using clinical decision curves.Results Logistic multifactor analysis showed that age(P=0.020 2)and vascular characteristics(P=0.002 2)were the independent predictors of the degree of the invasiveness of lung adenocarcinoma.The AUCs of the radiomics model,clinical model and combined model were 0.876,0.867 and 0.904 on the training set,and 0.828,0.828 and 0.864 on the test set,respectively.The difference between the ROC curves of the combined model and the clinical and radiomics models was not statistically significant(P>0.05)on the test set.Clinical decision curves showed a higher clinical benefit when using the combined model to predict the invasiveness under most conditions of threshold probability.Conclusion The combined model based on clinical and radiomics features enhances the predictive performance for the invasiveness of GGN-type lung adenocarcinoma.
ABSTRACT
Objective:To explore risk factors for clinical onset in children with uncontrolled self-limited epilepsy with centrotemporal spikes (SeLECTS) managed by 2 anti-seizure medications (ASMs).Methods:A total of 112 children with SeLECTS who were diagnosed at the Department of Pediatric Neurology of the Third Affiliated Hospital of Zhengzhou University from January 2018 to May 2021 were retrospectively reviewed.All of them were treated with conventional ASMs, and regularly followed up for 1-2 years.Types of therapeutic drugs, clinical seizure control status, presence of new seizure forms, electroencephalogram (EEG) were reviewed at follow-up visits.According to whether the seizures were controlled after the use of no more than 2 ASMs, patients were divided into poor response group (43 cases) and good response group (69 cases), and their clinical data and EEG characteristics were compared.Multivariate Logistic regression analysis was used to explore the risk factors for seizures that were uncontrolled by 2 ASMs. Results:There were significant differences in the age of onset ( χ2=8.919, P=0.003), seizure form ( χ2=4.218, P=0.040), seizure frequency ( Z=-7.664, P<0.001), EEG background slowing ( χ2=10.284, P=0.001), emergence of electrical status epilepticus during slow-wave sleep (ESES)( χ2=11.921, P=0.001), discharge generalization ( χ2=25.377, P<0.001), and presence of epileptic encephalopathy with spike-and-wave activation in sleep (EE-SWAS)( χ2=54.334, P<0.001) between groups.Multivariate Logistic regression analysis showed that seizure frequency ( P<0.001, OR=0.086, 95% CI: 0.022-0.329), discharge generalization ( P=0.006, OR=9.942, 95% CI: 1.918-51.527) and EEG background slowing ( P=0.041, OR=6.648, 95% CI: 1.077-41.038) were the 3 main risk factors associated with poor response to short-term medications of ASMs. Conclusions:Seizures are easily controlled in most SeLECTS patients medicated with ASMs with a favorable prognosis.Seizure frequency, discharge generalization and EEG background slowing are risk factors for the poor response to short-term pharmacotherapy in children with SeLECTS.
ABSTRACT
@#Abstract: Objective To investigate the influence of the variation of SARS-CoV-2 on the clinical feature, and to provide early warning signs for the variation of SARS-CoV-2 in clinical work. Methods From Jan 2, 2021 to Jun 30, 2021, a total of 105 COVID-19 patients were included in the study using a case-control method. Nasal swab samples were collected from the study subjects, the viral genes were sequenced, and patients were divided into Delta variant group and non-Delta variant group according to their gene sequences. Clinically relevant data were collected from the two groups, and indicators such as days of hospitalization, age distribution, lymphocytes, neutrophils, B lymphocytes, NK cells, IL-4, and IL-10 were compared; subgroup analysis was performed based on the number of days of viral negativity in the study subjects as the basis for grouping, and differences in immunological characteristics were compared, including lymphocytes, neutrophils, B lymphocytes, NK cells, IL-4, IL-10, etc. Results The theoretical hospitalization days of Delta variant group were (22.2±8.33) d, which were significantly longer than (17.6±10.50) d of non-Delta variant group (t=2.396, P<0.05). The total lymphocyte count and IL-4 of Delta variant group were (1.22±0.86) ×109/L and (0.80±0.23) ng/mL, which were significantly lower than corresponding (1.91±0.70) ×109/L and (1.59±0.59) ng/mL of non-Delta variant group (t=4.329, 9.072, P<0.05), while IL-10 was (7.16±7.77) ng/mL, which was significantly higher than (4.26±3.91) ng/mL of non-Delta mutation group (t=1.980, P<0.05). Subgroup analysis showed that the total lymphocyte count and IL-4 concentration in Delta variant group were (1.04±0.60) ×109/L and (0.74±0.25) ng/ml, which were significantly lower than corresponding (1.62±0.56) ×109/L and (1.56±0.52) ng/mL in non-Delta variant group, in patients with delayed discharge (P<0.05). Conclutions SARS-CoV-2 variant has an impact on clinical manifestations. The patient's B cell count and IL-10 concentration increased or IL-2 and IL-4 concentration decreased within 12 hours of admission indicated variant virus infection. The decrease of total lymphocyte count, especially T lymphocyte reduction, strongly suggests discharge delay due to viral clearance disorder.

OBJECTIVES@#To study the clinical and genetic features of Joubert syndrome (JS) in children.@*METHODS@#A retrospective analysis was performed on the clinical data, genetic data, and follow-up data of 20 children who were diagnosed with JS in the Department of Children's Rehabilitation, the Third Affiliated Hospital of Zhengzhou University, from January 2017 to July 2022.@*RESULTS@#Among the 20 children with JS, there were 11 boys and 9 girls. The common clinical manifestations were developmental delay (20 children, 100%), abnormal eye movement (19 children, 95%), and hypotonia (16 children, 80%), followed by abnormal respiratory rhythm in 5 children (25%) and unusual facies (including prominent forehead, low-set ears, and triangular mouth) in 3 children (15%), and no limb deformity was observed. All 20 children (100%) had the typical "molar tooth sign" and "midline cleft syndrome" on head images, and 6 children (30%) had abnormal eye examination results. Genetic testing was performed on 7 children and revealed 6 pathogenic genes, i.e., the CPLANE1, RPGRIP1L, MKS1, CC2D2A, CEP120, and AHI1 genes.@*CONCLUSIONS@#For children with developmental delay, especially those with abnormal eye movement and hypotonia, it is recommended to perform a head imaging examination to determine the presence or absence of "molar tooth sign" and "midline cleft syndrome", so as to screen for JS to avoid missed diagnosis and misdiagnosis. There are many pathogenic genes for JS, and whole-exome sequencing can assist in the diagnosis of JS.

OBJECTIVES@#To investigate the clinical manifestations and laboratory examination results of children with Kawasaki disease complicated by macrophage activation syndrome (KD-MAS), and to provide a basis for identifying early warning indicators for the early diagnosis and treatment of KD-MAS.@*METHODS@#A retrospective study was performed on 27 children with KD-MAS (KD-MAS group) and 110 children with KD (KD group) who were admitted to Wuhan Children's Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2014 to January 2022. Clinical and laboratory data were compared between the two groups. The receiver operating characteristic (ROC) curve was used to investigate the value of laboratory markers with statistical significance in the diagnosis of KD-MAS.@*RESULTS@#Compared with the KD group, the KD-MAS group had significantly higher incidence rates of hepatomegaly, splenomegaly, incomplete KD, no response to intravenous immunoglobulin, coronary artery damage, multiple organ damage, and KD recurrence, as well as a significantly longer length of hospital stay (P<0.05). Compared with the KD group, the KD-MAS group had significantly lower levels of white blood cell count, absolute neutrophil count, hemoglobin, platelet count (PLT), erythrocyte sedimentation rate, serum albumin, serum sodium, prealbumin, and fibrinogen (FIB), a significantly lower incidence rate of non-exudative conjunctiva, and significantly higher levels of C-reactive protein, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase (LDH), and serum ferritin (SF) (P<0.05). The ROC curve analysis showed that SF, PLT, FIB, and LDH had high value in the diagnosis of KD-MAS, with areas under the curve (AUC) of 0.989, 0.966, 0.932, and 0.897, respectively (P<0.001), and optimal cut-off values of 349.95 μg/L, 159×109/L, 3.85 g/L, and 403.50 U/L, respectively. The combination of SF, PLT, FIB, and LDH had a larger AUC than PLT, FIB, and LDH alone in the diagnosis of KD-MAS (P<0.05), but there was no significant difference in the AUC between the combination of SF, PLT, FIB, and LDH and SF alone (P>0.05).@*CONCLUSIONS@#KD-MAS should be considered when children with KD have hepatosplenomegaly, no response to intravenous immunoglobulin, coronary artery damage, and KD recurrence during treatment. SF, PLT, FIB, and LDH are of high value in the diagnosis of KD-MAS, especially SF is of great significance in the diagnosis of KD-MAS.

OBJECTIVES@#To study the differences in the clinical features of children with coronavirus disease 2019 (COVID-19) in different age groups during the epidemic of Omicron variant.@*METHODS@#A retrospective analysis was performed on the clinical data of 211 children with COVID-19 who were admitted to the Department of General Pediatrics, Zhongshan People's Hospital, from December 9, 2022 to January 8, 2023. According to their age, they were divided into 4 groups: 1 month-<1 year (n=84), 1-<3 years group (n=64), 3-<5 years (n=29), and ≥5 years (n=34). The above groups were compared in terms of general status, clinical features, ancillary examination results, treatment, and outcome.@*RESULTS@#The children aged <3 years accounted for 70.1% (148/211) of all hospitalized children with COVID-19, and the 3-<5 years group and the ≥5 years group had a significantly higher proportion of children with underlying diseases than the 1 month-<1 year group and the 1-<3 years group (P<0.05). Compared with the other three groups, the 1 month-<1 year group had significantly higher incidence rates of dyspnea, nasal congestion/nasal discharge, diarrhea and significantly lower incidence rates of convulsion and nervous system involvement (P<0.05). Moreover, compared with the other three groups, the 1 month-<1 year group had significantly higher incidence rates of increases in bile acid and creatine kinase isoenzyme and significantly lower incidence rates of decreased platelet count, increased neutrophil percentage, and decreased lymphocyte percentage (P<0.05). The 1 month-<1 year group had a significantly higher incidence rate of mild COVID-19 than the 1-<3 years group and a significantly lower incidence rate of severe/critical COVID-19 than the other three groups (P<0.05). Compared with the other three groups, the 1 month-<1 year group had a significantly higher proportion of children receiving oxygen inhalation therapy (P<0.05).@*CONCLUSIONS@#Children with COVID-19 in different age groups have different clinical features during the epidemic of Omicron variant, especially between the children aged 1 month to <1 year and those aged ≥1 year.

OBJECTIVE@#To investigate the expressions of Notch1 and Hes1 in diffuse large B-cell lymphoma (DLBCL), and their correlations with clinical features.@*METHODS@#Immunohistochemistry (IHC) was performed on DLBCL samples (54 cases) and lymphadenitis tissues (20 cases) to evaluate the expressions of Notch1 and Hes1, and analyze their correlations with clinical characteristics of patients. Based on Oncomine database, the expressions of Notch1 and Hes1 mRNA and DNA were also explored.@*RESULTS@#IHC result showed that the positive expression rates of Notch1 and Hes1 in DLBCL patients were significantly higher than those in the control group (P <0.05). In DLBCL patients, the expression of Notch1 was closely associated with B symptoms, Ann Arbor stage, lymphocyte count and the level of lactate dehydrogenase (P <0.05), while the expression level of Hes1 was significantly higher in patients with B symptoms (P <0.05). Notch+/Hes1+ expression was found in 21 DLBCL tissues (38.9%), and there was a correlation between Notch1 and Hes1 expression (r =0.296, P <0.05). Bioinformatics analysis (Oncomine database) showed that the mRNA expressions of Notch1 and Hes1 in the Brune dataset were significantly higher than those in the control tissues (P <0.05).@*CONCLUSION@#The expressions of Notch1 and Hes1 in DLBCL are significantly higher than those in lymphadenitis, and correlated with B symptoms and Ann Arbor stage, suggesting that Notch1 and Hes1 play important roles in the occurrence and development of DLBCL.

Objective To analyze the epidemiological characteristics of newly reported advanced schistosomiasis cases in Sichuan Province, so as to provide the evidence for analyzing the causes and formulating targeted control measures of newly reported advanced schistosomiasis cases. Methods Individual case investigation forms for advanced schistosomiasis cases were collected from the Sichuan Provincial Epidemic Annual Report System from 2011 to 2022, and patients’ demographics, previous medical history and liver parenchymal grading were retrieved. All advanced schistosomiasis cases’ medical records were reviewed, and the subtypes of schistosomiasis-endemic villages where the cases’ household registration were, floating population, survival and death and time of death were collected. Results A total of 321 newly reported advanced schistosomiasis cases were found in Sichuan Province from 2011 to 2022, with a male to female ratio of 0.99 to 1. There were 274 cases at ages of over 50 years (85.4%), with the highest proportion seen at ages of 60 to 69 years (87 cases, 27.1%), and splenomegaly was the most common type (180 cases, 56.1%), with no dwarfism type detected. The highest number of cases was reported in 2011 (78 cases), followed by in 2022 (74 cases), and the highest number of cases were reported in Meishan City (199 cases, 62.0%), Dongpo District (131 cases, 40.8%), and hilly subtype areas (136 cases, 42.4%). As of the end of 2022, there were 111 deaths due to advanced schistosomiasis, with the highest number of deaths seen in 2018 (25 deaths), and the highest mortality was seen among patients with the ascites type (41.2%). There were 47 (37.3%), 40 (59.5%) and 4 (23.5%) cases with grade III liver parenchyma among patients with splenomegaly, ascites, and colonic proliferation types, respectively, and there was a significant difference in the grading of III liver parenchyma among three types of patients (H = 12.092, P < 0.05), with more severe liver parenchyma injuries seen among patients with the ascites type than among those with splenomegaly and colonic proliferation type (Z = 24.262 and 44.738, both Padjusted values < 0.05). Conclusions There have been newly reported advanced schistosomiasis cases in Sichuan Province during recent years, and patients with the ascites type should be given a high priority among advanced schistosomiasis cases in Sichuan Province. Intensified clue surveys are needed for early identification and treatment of advanced schistosomiasis cases, so as to increase the survival rate and improve the quality of life.
