OBJECTIVE: To explore the clinical phenotypes and genetic characteristics of a child with Acid-labile subunit deficiency (ALS). METHODS: A male child diagnosed with ALS at Dongguan Maternal and Child Health Care Hospital in March 2021 was selected as the study subject. Clinical data of his family was collected. Peripheral blood samples were collected from the child and his parents. Following extraction of genomic DNA, whole-exome sequencing (WES) was carried out, and Sanger sequencing was used for family verification of candidate variants. Based on guidelines from the American College of Medical Genetics and Genomics (ACMG), the pathogenicity of the candidate variant was classified. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: 2020-6). RESULTS: The patient, a 5-year-and-7-month-old boy, presented with short stature and delayed bone age. Endocrine examinations showed decreased serum concentrations of insulin-like growth factor-1 (IGF-1) and IGF binding protein-3 (IGFBP3). WES revealed that he has harbored compound heterozygous variants of the IGFALS gene, namely c.741_742del, p.Y248Pfs83 and c.272del, p.P91Rfs31. Sanger sequencing verified that the variants were inherited from his father and mother, respectively. According to the ACMG guidelines, c.741_742del, p.Y248Pfs83 and c.272del, p.P91Rfs31 variants were classified as likely pathogenic (PVS1+PM2_supporting). Based on the pre-set literature search strategy, 11 research literature on ALS were retrieved, which involved a total of 33 families and 62 patients. Combined with the patient in this study, 31 IGFALS gene variants were identified among the 63 patients, which mainly consisted of missense variants (20 types), with variant sites concentrated in exon 2. The main clinical features were short stature in conjunct with delayed puberty, with a significant genotype-phenotype correlation. CONCLUSION The IGFALS gene variants NM_004970.2: c.741_742del, p.Y248Pfs83 and c.272del, p.P91Rfs31 may be the genetic etiology in this family. This study has expanded the variant spectrum of the IGFALS gene and provided valuable information for the diagnosis, genetic counseling and clinical treatment of the disease.

Forty adult male C57BL/6 mice were randomly divided into four groups:the control group,Salmonella typhimurium(S.typhimurium)(ST)group,phlorizin(PHZ)+S.typhimuri-um(ST)group,and PHZ(80 mg/kg)group,with 10 mice in each group.Morphological observa-tion,HE staining,ELISA,immunofluorescence and Western blot were performed,the results showed that PHZ significantly increased the cecal index,decreased the spleen index of S.typhi-murium-induced mice(P＜0.05),and reduce the pathological damage of cecum in mice.Mean-while,PHZ treatment also significantly reduced colonization of S.typhimurium in the cecum,spleen,mesenteric lymph nodes and liver(P＜0.05).The results of ELISA showed that PHZ treatment also significantly inhibited the S.ty phimurium-induced increase in the expression of IL-1β,INF-γ,TNF-a and IL-6 in the cecum of mice(P＜0.05).Immunofluorescence and Western blot results showed that PHZ significantly increased the protein expression levels of Occludin,Claudin-3,and ZO-1 in the cecal barrier of mice induced by S.typhimurium(P＜0.05).These results con-firmed that phlorizin could improve cecal inflammation and intestinal barrier damage induced by S.typhimurium in mice.

Objective To investigate the effects of a continuous-dose administration versus different dosage regimens of polyethylene glycol electrolyte solution(PEG)taken in two doses with a 12-hour interval on bowel cleansing efficacy,with the goal of optimizing bowel preparation protocols and improving patient tolerability.Methods 232 patients who underwent painless colonoscopy and used PEG as a bowel cleanser from June 2024 to September 2024 were selected as study subjects.Participants were divided into three groups:the control group(3.00 L PEG continuous dose),experimental group A(0.75 L+2.25 L PEG),and experimental group B(1.50 L+1.50 L PEG).All patients underwent painless colonoscopy within 4～6 h after completing PEG intake.The interval between the two doses of PEG in group A and group B was 12 h.The bowel cleansing efficacy was assessed by using the Boston bowel preparation scale(BBPS),and the rates of colon polyp detection,adverse reactions,sleep duration,and tolerability were recorded.Results There were no significant statistical differences in BBPS scores and colon polyp detection rates among the three groups(P>0.05).Experimental group B experienced the least adverse reactions,followed by experimental group A,while the control group reported the most significant adverse reactions(P<0.05).The timing of PEG administration did not have a significant impact on sleep duration among the three groups(P>0.05).Patients in experimental group B showed good tolerability to PEG and were willing to accept this bowel preparation regimen,followed by group A,while the control group exhibited the poorest tolerability,with significant statistical differences among the three groups(P<0.05).Conclusion The continuous administration and divided administration of PEG have no significant impact on the effectiveness of intestinal cleansing and the detection rate of colonic polyps.However,the divided PEG regimen with a 12 h interval results in fewer adverse reactions and better tolerance,especially the optimal regimen of taking 1.50 L PEG in two doses with a 12 h interval.

AIM:To study the mechanism of oxy-sophoridine(OSR)in relieving neuropathic pain(NP).METHODS:The analgesic effect of OSR was observed by measuring mechanical pain sensitivity.By combining OSR with agonists and antagonists re-lated to synthesis and metabolism of gamma ami-nobutyric acid(GABA),the mechanism related to analgesic effects of OSR and GABA nervous system is studied.The expression of c-Fos immunopositive cells and the expression of c-Fos and Glutamic acid decarboxylase(Glutamic acid decarboxylase 67)in brain and spinal cord were detected by immunoflu-orescence staining.Co-expression of GAD67,GABA transporter 1(gamma-Aminobutyric acid Transport-er 1,GAT-1)immunopositive cells.RESULTS:Com-pared with Sham group,spared nerve injury(SNI)group showed increased mechanical pain sensitivi-ty,increased expression of c-Fos immunopositive cells,decreased and increased co-expression of c-Fos and GAD67 and GAT-1 immunopositive cells,re-spectively.Compared with SNI group,mechanical algesia in OSR 500 and 1 000 mg/kg groups was de-creased,algesia in OSR 250 mg/kg combined with antagonist group was decreased,and algesia in OSR 500 mg/kg combined with agonist group was increased.The co-expression of c-Fos and GAD67 immunopositive cells in the brain and spinal cord of OSR 500 mg/kg group increased,while the co-ex-pression of c-Fos and GAT-1 decreased.CONCLU-SION:OSR has a good analgesic effect on NP mice induced by SNI.The mechanism is that OSR increas-es the content of central GABA by up-regulating GABAergic neurons in brain and spinal cord.

BACKGROUND:Scoliosis mainly refers to sequence abnormalities in the coronal,sagittal,and axial positions of the spine,with a Cobb angle of≥10°.The patients may experience symptoms such as unequal shoulder height and back asymmetry.Severe cases may affect the patient's cardiopulmonary function,thereby affecting their daily life.Conservative treatment can control the progression of scoliosis and avoid later surgery.Scoliosis orthosis is currently a commonly used and effective treatment measure in conservative treatment. OBJECTIVE:To summarize and analyze the current research status,hotspots,and trends of scoliosis orthoses both domestically and internationally,providing reference for related research. METHODS:Using bibliometrics and visual analysis as tools,and using a comparison between China and foreign countries as a method,this paper analyzes the literature on scoliosis orthosis journals in the past decade.Based on bibliometrics,the current status of research on scoliosis orthoses is determined.Citespace software is used to analyze key words and identify the current hotspots and future trends in scoliosis orthosis research. RESULTS AND CONCLUSION:(1)At present,the number of literature on scoliosis orthoses is still on a fluctuating upward trend.China and the United States are the main countries for research,with a literature share of over 40%.However,the average citation rate of foreign language literature by Chinese scholars is relatively low.(2)The basic fields of domestic research are mainly surgery and pediatrics,while orthotics and clinical neurology are mainly studied abroad.Among them,there is also a certain number of documents in domestic Chinese medicine,indicating that China is also engaged in the combination of Chinese and Western treatment of scoliosis.The National Natural Science Foundation of China has the highest proportion in the aspect of Chinese and foreign literature,reflecting the importance of the fund attaches to the research of scoliosis orthosis.(3)The authors with the highest number of publications are Qiu Yong and Negrini Stefano,and the most published institutions are the Spinal Surgery Department of Gulou Hospital affiliated to Nanjing University Medical College and UDICE-French Research University.Domestic and foreign authors and institutions have certain communications about this,but not closely,which requires relevant institutions and scholars to further explore and study.(4)From the research hotspots and future trends,the main treatment type is adolescent idiopathic scoliosis,while the production method of the short-column side bending orthosis is three-dimensinoal printing,and the main treatment index is convex progression.The ultimate purpose of treatment is to improve the quality of life of the patients.

Objective:To explore brain network properties and their relationship with cognitive function in children with spastic cerebral palsy (SCP) using diffusion tensor imaging (DTI) based graph theory analysis.Methods:The study was a cross-sectional study. Clinical and imaging data of 21 children with SCP (SCP group) and 32 healthy children (control group) who underwent cranial MRI at the Affiliated Hospital of Zunyi Medical University from August 2020 to April 2022 were analyzed retrospectively. 3D-T 1WI, DTI and Wechsler Intelligence Scale were assessed for all subjects. The Wechsler Intelligence Scale included the verbal comprehension index (VCI), the processing speed index (PSI), the work memory index (WMI), and the perceptual reasoning index (PRI), etc., and ultimately the full scale intelligence quotient (FSIQ) scores were obtained based on the indices of each subscale. Independent samples t-test was used to analyze the differences in the small world attributes [small-world index (σ), normalized shortest path length (λ), normalized clustering coefficients (γ)], global attributes [global efficiency (Eglob), local efficiency (Eloc), characteristic path length (Lp), clustering efficiency (Cp)] and node attributes [degree centrality(DC), nodal efficiency (Ne), betweeness centrality (Bc), nodal shortest path length (NLp), nodal clustering efficiency, nodal local efficiency] between two groups of children′s brain networks. Brain network indicators with statistically significant differences between the 2 groups were correlated with Wechsler Intelligence Scale scores using Spearman. Results:The FSIQ scores on the Wechsler Intelligence Scale and the VCI, WMI, PSI, and PRI were lower in the SCP group than in the control group, and the differences were all statistically significant (all P<0.05). Both groups of children′s brain networks had small world properties. Compared with the control group, Eglob decreased, Lp and λ increased in the SCP group (all P<0.05). Compared with the control group, DC and Ne in multiple brain regions decreased, NLp increased in the SCP group (all P<0.05, FDR corrected). Correlation analysis showed that DC in the right parsopercularis was positively correlated with FSIQ, VCI, WMI and PRI( r=0.53, 0.47, 0.47, 0.60, P=0.019, 0.045, 0.044, 0.020, respectively); NLp in the right parsopercularis was negatively correlated with PRI( r=-0.56, P=0.030); Ne in left paracentral, the right parsopercularis, right precentral, right postcentra were positively correlated with PRI( r=0.62, 0.56, 0.53, 0.54, P=0.015, 0.031, 0.044, 0.039, respectively); Ne in the right precentral was positively correlated with WMI ( r=0.48, P=0.039) in the SCP group. Conclusions:There are changes in the topological attributes of global and multiple regional brain networks in SCP. The changes in the attributes of nodes in the right parsopercularis, right precentral, right postcentral, and left paracentral could reflect cognitive dysfunction in children with SCP.
