Objective:To evaluate the effects of two dressing methods on wound healing and patient satisfaction after cosmetic suturing for pediatric facial trauma.Methods:A prospective randomized controlled trial was conducted at Dongying People′s Hospital from October 2022 to October 2023. A total of 180 pediatric patients [105 males, 75 females, aged 3-7 (3.9±1.4) years] with facial trauma requiring cosmetic suturing were enrolled in this study. Participants were randomly divided into the study group ( n=91) and control group ( n=89) using a random number table. During the first postoperative dressing change at 24 hours, the study group received saline cleaning followed by erythromycin ointment coverage, while the control group underwent iodine disinfection with gauze coverage. Pain intensity during the second dressing change was assessed using the Chinese version of the Children′s Hospital of Eastern Ontario pain scale (CHEOPS). Wound healing at 6-7 days post-suturing was evaluated using the Chinese version of the redness, edema, ecchymosis, discharge, and approximation (REEDA) scale. Scar appearance at 14 days was measured via the Stony Brook scar evaluation scale (SBSES). Complication rates (infection, dehiscence) and satisfaction rates were statistically analyzed. Results:During the second dressing change, the CHEOPS score was significantly lower in the study group (6.27±1.32) than that in the control group (6.89±1.21) ( P=0.001). At 6-7 days, the REEDA score in the study group (2.26±1.91) was significantly lower than that in the control group (3.07±2.13) ( P=0.008). At 14 days, the SBSES score was significantly lower in the study group [2.60±1.42) vs (3.89±1.50), P<0.001]. The infection rate was 1.09% (1/91) in the study group and 1.12% (1/89) in the control group, with two cases of epidermal dehiscence observed in the control group. The satisfaction rate in the study group was 93.41% (85/91), which was higher than that in the control group [85.49% (76/89), P=0.020]. Conclusion:Saline cleaning combined with erythromycin ointment coverage reduces pain during wound dressing change, facilitates early wound healing, and improves patient′s satisfaction.

Objective:To explore the clinical application values of radiofrequency thermocoagulation (RF-TC) based on stereotactic electroencephalogram (SEEG) high-frequency oscillations (HFOs) analysis in patients with refractory epilepsy.Methods:Fourteen patients with refractory epilepsy treated with SEEG-guided RF-TC were selected from Department of Neurosurgery, PLA Western Theater Command General Hospital from August 2019 to December 2021. Automatic detection algorithm of Matlab was used to calculate the HFOs incidence in each montage, and the fitting curves of HFOs incidences were used to formulate the threshold of HFOs and delimit the HFOs regions (ripples and fast ripples). These patients were divided into non-seizure group and seizure group according to the prognoses 3 and 6 months after RF-TC. At the last follow-up, these patients were divided into good prognosis group and poor prognosis group according to Engel grading; the differences of ripple thermocoagulation rate and fast ripple thermocoagulation rate between the 2 groups were compared.Results:A total of 7,332 ripples and 1,144 fast ripples were detected in SEEG data from 14 patients. Six months after surgery, neurological dysfunction incidence was 14.3%, without permanent neurological dysfunction, intracranial infection, intracranial hemorrhage, or electrode equipment failure. Within 3 months of RF-TC, seizure-free rate was 71.4% (10/14), and fast ripple thermocoagulation rate in non-seizure group was significantly higher than that in seizure group ( P<0.05); within 6 months of RF-TC, seizure-free rate was 57.1% (8/14), and ripple thermocoagulation rate in non-seizure group was significantly higher than that in seizure group ( P<0.05). At last follow-up, 6 patients had good prognosis and 8 patients had poor prognosis; the ripple thermocoagulation rate in good prognosis group was significantly higher than that in poor prognosis ( P<0.05). Conclusions:HFOs can assist in designating epileptogenic regions. Patients with wider range of thermocoagulation ripples or fast ripples will have better short-term efficacy; patients with wider range ofthermocoagulation ripples will have better prognosis.

OBJECTIVE: To carry out genetic testing for a patient with 45,X/46,XY mosaicism and autism spectrum disorder (ASD). METHODS: Peripheral blood samples of the patient and his parents were collected for the extraction of genomic DNA. Trio-based whole exome sequencing and Sanger sequencing were carried out thereafter. RESULTS: The proband and his father were found to harbor a heterozygous c.4781G>A (p.Arg1594Gln) variant of the CACNA1I gene. In addition, the proband was also found to harbor a de novo c.268C>T (p.Arg90Trp) missense variant of the MTRR gene. Based on guidelines of the American College of Medical Genetics and Genomics (ACMG), the c.4781G>A (p.Arg1594Gln) variant of the CACNA1I gene was predicted to be pathogenic (PVS1, PM1, PM2, PP3), while the c.268C>T (p.Arg90Trp) variant of the MTRR gene was predicted to be of uncertain significance. CONCLUSION Variants of the CACNA1I and MTRR genes, together with the chromosomal mosaicism, may have predisposed to the susceptibility to the ASD in this patient.

Objective:To investigate the characteristics and change trends of electroencephalogram (EEG) in patients with drug resistant epilepsy (DRE) after vagus nerve stimulation (VNS).Methods:Twenty-five patients with DRE, admitted to our hospital from July 2016 to May 2019, were chosen; all patients accepted VNS and followed up for 12 months. Long range video EEG (VEEG) monitoring was performed before VNS, and 3, 6 and 12 months after VNS, and the tracing time of each monitoring was longer than 12 h. The EEG characteristics of these patients before and different times after VNS were analyzed.Results:In the VEEG monitoring before VNS, 25 patients showed sharp wave, spike wave, sharp slow wave, and compound spike slow wave in the interictal period; 3 patients (12%) could locate the brain region. The interictal EEG of 11 patients 3 months after VNS showed different degrees of improvement as compared with the preoperative one, which manifested as mixed rhythms: mono-spiking as sharp wave, sharp slow wave or spike wave; 8 patients had McHugh grading I-II. The interictal EEG of 18 patients 6 months after VNS showed different degrees of improvement as compared with the preoperative one; 11 patients had McHugh grading I-II. The interictal EEG of 21 patients 12 months after VNS showed different degrees of improvement as compared with the preoperative one; 15 patients had McHugh grading I-II.Conclusion:The EEG improvement effect of DRE patients after VNS is gradually improved with time; in some patients, the EEG improvement is earlier than improvement of clinical symptoms.

Objective:This study aimed to compare the efficacy and safety of cladribine, smustine, etoposide, cyclophosphamide, and cytarabine (C+SCAV) and smustine, etoposide, cytarabine, and melphalan (SEAM) conditioning regimens in autologous stem cell transplantation (auto-HSCT) for non-Hodgkin’s lymphoma (NHL) .Methods:A retrospective analysis was conducted on 61 NHL patients who received auto-HSCT in the Department of Hematology, the First Affiliated Hospital of Suzhou University, from March 2018 to May 2021. The C + SCAV group and SEAM group had 19 and 42 patients, respectively.Results:① Among the 61 patients with NHL, 37 were male and 24 were female. The median age was 48 (21-66) years old. There were 19 cases in the C+SCAV group and 42 cases in the SEAM group. There was no significant difference in the baseline characteristics between the two groups ( P>0.05) . ② The median time to neutrophil and platelet engraftment in the C+SCAV cohort were 10 (8-15) days and 13 (9-22) days, respectively, which does not differ from the SEAM group ( P=0.103, P=0.403) . ③ No differences existed between the two groups in terms of survival. The 1-year progression-free survival (PFS) was (76.5±10.3) % for patients receiving C+SCAV and (78.4±6.8) % for those who received SEAM ( P=0.841) . The 1-year overall survival was 100.0% for the C+SCAV group and 95.2±3.3% for the SEAM group ( P=0.339) . ④The 1-year PFS of patients with complete remission in the C+SCAV group was similar to those who in the SEAM group [ (92.3±7.4) % vs (82.5±7.2) %, P=0.406]. ⑤ The incidence of non-hematological serious adverse events (≥ grade 3) in the C+SCAV group and SEAM group were 10.5% (2/19) and 40.5% (17/42) ( P=0.013) , the incidence of severe mucositis was 5.3% (1/19) and 31.0% (13/42) ( P=0.015) , and the incidence of severe infection (≥ grade 3) was 10.5% (2/19) and 19.0% (8/42) ( P=0.389) , respectively. Conclusion:C + SCAV conditioning regimen appeared to be no different from the SEAM regimen in terms of survival. It can lower the incidence of SAE and does not increase the risk of severe infection. As a result, it can be used as an alternative conditioning regimen for lymphoma patients undergoing auto-HSCT.

OBJECTIVE: To analyze the pathogenic variants of the KIF1A gene and its corresponding protein structure in an autism spectrum disorder (ASD) family trio carrying harmful missense variants in the KIF1A gene. METHODS: The peripheral blood DNA of the patient and his parents was extracted and sequenced using whole exome sequencing (WES) technology and verified by Sanger sequencing. Bioinformatics software SIFT, PolyPhen-2, Mutation Taster, and CADD software were used to analyze the harmfulness and conservation of variants. The Human Brain Transcriptome (HBT) database was used to analyze the expression of the KIF1A gene in the brain. PredictProtein and SWISS-MODEL were further used to predict the secondary structure and tertiary structure of KIF1A wild-type protein and variant protein. PyMOL V2.4 was utilized to investigate the change of hydrogen bond connection after protein variant. RESULTS: The WES sequencing revealed a missense variant c.664A>C (p.Asn222His) in the child's KIF1A gene, and this variant was a de novo variant. The harmfulness prediction results suggest that this variant is harmful. By analyzing expression level of KIF1A gene in the brain. It is found that KIF1A gene widely expressed in various brain regions during embryonic development. By analyzing the variant protein structure, the missense variant of KIF1A will cause many changes in the secondary structure of protein, such as alpha-helix, beta-strand, and protein binding domain. The connection of hydrogen bond and spatial structure will also change, thereby changing the original biological function. CONCLUSION The KIF1A gene may be a risk gene for ASD.

The myelin-associated protein Nogo-A was considered to be the axon growth inhibitory factor, which participates in a variety of pathophysiological regulation of nervous system. In recent years, a growing number of studies have shown that Nogo-A protein is closely related to epilepsy by regulating dendritic plasticity, mediating abnormal nerve migration and regulating glial cell activation, etc. This article will review the research progress of Nogo-A in epilepsy in recent years.

In order to search for new anti-inflammatory agents with strong activity and less toxicity relative to CDDO-Me, the ester prodrugs 2-8 of CDDO-Me were synthesized by treatment of oleanolic acid(OA)with DMF/K2CO3 to generate 1, followed by esterification of 1 with various aliphatic and aromatic carboxylic acids, respectively. All the target compounds showed strong inhibitory effects on LPS-induced NO production in RAW 264. 7 cells. Among them, compounds 2 and 7 possessed the most potent inhibitory effects with IC50=(2. 34±0. 67)and(3. 83±0. 97)nmol/L, respectively. Moreover, MTT assay indicated that all the target compounds(2-8)displayed much weaker anti-proliferative activity against RAW 264. 7 cell lines than CDDO-Me, suggesting that they may be less toxic than CDDO-Me.
