To compare the different hepatic portal exposure techniques in Kasai surgery during their different perioperative periods / 中华肝胆外科杂志

Objective:To compare the impact of different portal exposure techniques in the Kasai surgery on children with type Ⅲ. biliary atresia during their different perioperative periods.Methods:A retrospective study was performed on the data of children with type Ⅲ. biliary atresia who underwent Kasai surgery at Fujian Children's Hospital from January 2017 to October 2020. Of 45 children enrolled in this study, there were 24 males and 21 females, aged (71.3±21.0) days. Patients who had left and right branches of the portal vein and the left and right hepatic arteries in the portal area being completely freed and elastically stretched during the Kasai operation were included into the free group ( n=22) and the remaining patients were included in the control group ( n=23). Postoperative hospital stay, postoperative direct bilirubin levels, postoperative complications and transplant-free survival after the Kasai operation were compared between the 2 groups. Results:Postoperative hospital stay of (17.1±4.4) d in the free group was significantly lower than that in the control group (20.1±5.4) d, ( t=2.07, P=0.044). The direct bilirubin level at 3 months after surgery for the control group was 30.0 (109, 108.0)μmol/L, which was significantly higher than that of 14.5 (4.0, 37.5) μmol/L in the free group ( Z=-2.16, P=0.031). Twenty-one patients (91.3%) in the control group had frequent attacks of postoperative cholangitis, compared with 13 patients (59.1%) in the free group. The difference was statistically significant (χ 2=4.69, P=0.030). Eleven surviving patients (47.8%) in the control group did not undergo liver transplantation at one year after surgery, compared with 15 patients (68.2%) in the free group. At two years after surgery, 7 surviving patients (30.4%) in the control group did not undergo liver transplantation compared with 10 patients (45.5%) in the free group. Conclusion:For children with type Ⅲ. biliary atresia, completely freeing the left and right branches of portal vein, and left and right hepatic arteries in the liver portal area, and elastically stretching these vessels to expose the portal area of the liver during Kasai surgery increased surgical safety and reduced hospital stay.

Human hair follicle-derived mesenchymal stem cells promote tendon repair in a rabbit Achilles tendinopathy model / 中华医学杂志(英文版)

BACKGROUND@#Hair follicles are easily accessible and contain stem cells with different developmental origins, including mesenchymal stem cells (MSCs), that consequently reveal the potential of human hair follicle (hHF)-derived MSCs in repair and regeneration. However, the role of hHF-MSCs in Achilles tendinopathy (AT) remains unclear. The present study investigated the effects of hHF-MSCs on Achilles tendon repair in rabbits.@*METHODS@#First, we extracted and characterized hHF-MSCs. Then, a rabbit tendinopathy model was constructed to analyze the ability of hHF-MSCs to promote repair in vivo . Anatomical observation and pathological and biomechanical analyses were performed to determine the effect of hHF-MSCs on AT, and quantitative real-time polymerase chain reaction, enzyme-linked immunosorbent assay, and immunohistochemical staining were performed to explore the molecular mechanisms through which hHF-MSCs affects AT. Furthermore, statistical analyses were performed using independent sample t test, one-way analysis of variance (ANOVA), and one-way repeated measures multivariate ANOVA as appropriate.@*RESULTS@#Flow cytometry, a trilineage-induced differentiation test, confirmed that hHF-derived stem cells were derived from MSCs. The effect of hHF-MSCs on AT revealed that the Achilles tendon was anatomically healthy, as well as the maximum load carried by the Achilles tendon and hydroxyproline proteomic levels were increased. Moreover, collagen I and III were upregulated in rabbit AT treated with hHF-MSCs (compared with AT group; P  < 0.05). Analysis of the molecular mechanisms revealed that hHF-MSCs promoted collagen fiber regeneration, possibly through Tenascin-C (TNC) upregulation and matrix metalloproteinase (MMP)-9 downregulation.@*CONCLUSIONS@#hHF-MSCs can be a treatment modality to promote AT repair in rabbits by upregulating collagen I and III. Further analysis revealed that treatment of AT using hHF-MSCs promoted the regeneration of collagen fiber, possibly because of upregulation of TNC and downregulation of MMP-9, thus suggesting that hHF-MSCs are more promising for AT.

Objective:To investigate the clinical characteristics of patients with combined oxidative phosphorylation deficiency type 4 (COXPD4) related to TUFM gene variation, in order to improve clinicians′ understanding of the disease. Methods:A case of COXPD4 with cystic leukodystrophy admitted to the Children′s Hospital of Zhengzhou University in June 2021 was taken as the study subject, and her clinical characteristics and genetic testing results were retrospectively analyzed. The "combined oxidative phosphorylation deficiency type 4" " TUFM gene" "cystic leukodystrophy" "combined oxidative phosphorylation deficiency 4" "COXPD 4" " TUFM" and "cystic leukodystrophy" were used as keywords, and the documents on COXPD4 related to TUFM gene mutations were reviewed from Wanfang Data Knowledge Service Platform, CNKI, PubMed Document Database, and National Center for Biotechnology Information (NCBI) until August 2021. The COXPD4 patients that have been reported internationally were analyzed for clinical features and variant types. Results:The patient was a 2-month-old girl with clinical manifestations of delayed development and progressive aggravation, elevated lactic acid in serum and cerebrospinal fluid, and diffuse white matter dysplasia with multiple cystic lesions in cerebral magnetic resonance imaging (MRI). Whole exome sequencing showed TUFM gene complex heterozygous variants c.684_684+4delGGTGA and c.1105C>T, which had not been reported in the past. A total of 5 cases of COXPD4 were reported in 4 English literatures. Together with 1 case in this study, there were 4 cases with detailed clinical history data, including 1 male and 3 females. The clinical manifestations were severe early-onset lactic acidosis and developmental lag, and 3 cases were accompanied by progressive infantile encephalopathy. Among them, 3 cases underwent head MRI examination, all of which showed diffuse white matter signal with multiple cystic lesions, 2 cases with basal ganglia involvement and multiple cerebellar gyri deformity. Genetic test indicated different types of TUFM gene variation. Conclusions:COXPD4 is a rare hereditary mitochondrial disease. For cases with COXPD4 clinical and imaging features, TUFM gene mutations can be screened first.

Phenotypic and genetic analysis of a case with hypohidrotic ectodermal dysplasia due to Xq13.1 microdeletion / 中华医学遗传学杂志

OBJECTIVE@#To investigate the clinical phenotype and genetic characteristics of a patient with hypohidrotic ectodermal dysplasia (HED) due to partial deletion of EDA gene.@*METHODS@#The child has presented with HED complicated with epilepsy. Family trio whole exome sequencing (Trio-WES), copy number variation sequencing (CNV-seq), and karyotype analysis were carried out to explore the underlying genetic etiology.@*RESULTS@#The proband, a 7-year-and-8-month-old boy, presented with thin curly hair, thin and sparse eyebrow, xerosis cutis, susceptibility to hyperthermia from childhood, hypohidrosis, sharp/sparse/absent teeth, saddle nose, prominent forehead, auricle adulation and seizure. He was found to have a normal chromosomal karyotype, and no abnormality was found by Trio-WES. Genome-wide CNV-seq revealed a 341.90 kb deletion at Xq13.1q13.1 (chrX: 68 796 566-69 138 468). As verified by PCR-electrophoresis, the deletion has removed part of the EDA gene. The deletion was derived from his mother with normal hair, mild xerosis cutis, and sparse, decidulated and nail-like teeth. The mother was detected with a heterozygous 242.10 kb deletion at Xq13.1q13.1 (chrX: 68 836 154-69 078 250).@*CONCLUSION@#Both the proband and his mother have carried a Xq13.1 microdeletion involving part of the EDA gene. The clinical phenotypes of the mother and the proband were consistent with the clinical characteristics of X-linked recessive HED, for which partial deletion of the EDA gene is probably accountable.

Objective:To investigate the clinical phenotype and summarize the genetic characteristics of children with neurofibromatosis type 1 (NF1) diagnosed by next-generation sequencing.Methods:The clinical data of 12 children with NF1 who were admitted to the Department of Neurology of the Children's Hospital Affiliated to Zhengzhou University from December 2017 to October 2019 were retrospectively analyzed. The next-generation sequencing method was used to sequence the NF1 gene of the probands and the mutations were verified by PCR-Sanger sequencing.Results:Among the 12 children diagnosed with NF1 (male: female=11: 1), who aged from seven months to 11 years old, the main complaints were seizures and skin with café-au-lait spots. Five children were found with freckles in axillae, and two with cutaneous neurofibroma. Six cases had seizures, two children suffered spastic seizures, two with generalized tonic-clonic seizures, one with typical absence seizure, one with focal seizure, one case had severe headache and vomiting. Fortunately for the children with seizures, anti-epileptic drugs had a good prognosis. There were five mutation types detected in 12 cases, including one case of loss of overall heterozygosity in NF1 gene; three missense mutations: c.7867C>A (p.L2623I), c.7855C>A (p.L2619I) and c.7792C>A(p.L2598I); three frameshift mutations: c.3162delC(p.N1054Nfs *8), c.540dupA (p.Q181Tfs *20) and c.2027dupA(p.V679Pfs *21); three nonsense mutations: c.1467T>A(p.Y489X, 2351), c.1318C>T(p.R440X, 2400) and c.1411C>T(p.K471X, 2369); two splicing mutations: c.2326-2(IVS10)G>C and c.1186-1(IVS10)G>C. Nine children were found with spontaneous mutations, one case was inherited from the father, and two cases were inherited from the mother. c.7867C>A(p.L2623I), c.7855C>A(p.L2619I), c.3162delC(p.N1054Nfs *8), c.1411C>T(p.K471X, 2369), c.2326-2(IVS10)G>C, c.1186-1(IVS10)G>C were unreported mutations in literature. Conclusions:NF1 is caused by NF1 gene mutation. The early clinical manifestations of children with NF1 defect presented with café-au-lait spots, and some suffered seizures. For patients with multiple café-au-lait spots and seizures in the clinic, genetic analysis should be performed as soon as possible to confirm the diagnosis.

Analysis of the clinical phenotype and tripeptidyl peptidase-1 gene mutation in a family with type 2 neuronal ceroid lipofuscinosis / 中华神经科杂志

Objective:To summarize the clinical phenotype and tripeptidyl peptidase-1 (TPP1) gene mutation characteristics in a family with type 2 neuronal ceroid lipofuscinosis (CLN2) confirmed by second generation sequencing. Methods:The clinical data of a family with CLN2 from the Department of Neurology of the Children′s Hospital Affiliated to Zhengzhou University in June 2018 were collected. The proband was confirmed by using the whole-exome sequencing and the Sanger test of the first generation was used in the family members, and the mutation characteristics of TPP1 gene were analyzed, and the clinical features were summarized.Results:The proband is a three-year- and nine-month-old girl, presented with generalized tonic-clonic seizures, normal mental function, mild backward development of language and movement. The ophthalmic examination showed binocular ametropia, normal visual acuity, and no macular degeneration. Cranial magnetic resonance imaging (MRI) showed widening of the subarachnoid space in the frontotemporal region, deepening of the sulci, and cerebellar atrophy. There were two heterozygous mutations in the TPP1 gene, from her parents with normal phenotypes respectively. The c. 1449-1450insG (p.I484Dfs*7) mutation comes from her father, which is an unreported heterozygous mutation of code-shifting, whereas the c.1417G>A(p.G473R) mutation comes from her mother, which is a known missense mutation, consistent with the characteristic of CLN2 complex heterozygous mutation. The proband′s elder brother, whose first symptom was myoclonic seizure at the age of three, and now he is seven years old with progressive visual impairment and regression of intellectual, motor and cognitive functions. The ophthalmic examination showed retinal degeneration, and the cranial MRI showed whole-brain atrophy with obvious cerebellar atrophy. The pathogenic gene of TPP1 and the complex heterozygous mutation site were consistent with the proband. Now the proband′s younger brother is 2-year- and 10-month-old, whose phenotype is normal, with a single heterozygous mutation of c.1417G>A (p.G473R), which comes from their mother, and the parents of the proband have no clinical phenotype. Conclusions:CLN2 is a rare lysosomal storage disorder that is characterized by seizures, progressive mental and motor deterioration, loss of vision and brain atrophy on MRI, binocular macular degeneration. TPP1 complex heterozygous mutation c. 1449-1450insG(p.I484Dfs*7) and c.1417G>A(p.G473R) is the genetic cause of this case.

Objective:To investigate the clinical characteristics and mutation of MFSD8 gene in a family with neuronal ceroid lipofuscinosis type7 (CLN7).Methods:The clinical data of a CLN7 patient and her family from the Children′s Hospital Affiliated to Zhengzhou University in January 2018 were reviewed and analyzed. Whole exome sequencing of second-generation sequencing was used to analyze gene mutation results.Results:The proband, a five years and nine months old girl, admitted to the Children′s Hospital Affiliated to Zhengzhou University with the chief complaint of "intermittent seizures for seven months". She had the first seizure at the age of five years and two months, and different types of generalized tonic-clonic and atypical absence seizures were found. At the age of five years and nine months, she was admitted to the hospital with mild mental deterioration. She had normal motor and physical development. Ophthalmological evaluation revealed macular degeneration. The video electroencephalography revealed multifocal spikes or spike-and-wave, prominent in the anterior fronto-temporal regions. Magnetic resonance imaging (MRI) revealed cerebellar atrophy. Compound heterozygous mutations c.553 (exon 6) G>A and c.1391 (exon 13) C>T were found on her MFSD8 gene, supporting the diagnosis of CLN7. Each of her parent carried one of the mutations, and c.553 (exon 6) G>A was a new mutation. Her elder brother had the first seizure at the age of 6 years, with motor and mental deterioration as well as visual impairment. MRI revealed generalized cerebral atrophy. He had the same compound heterozygous mutations with his sister. No pathogenic mutation was found in her younger brother.Conclusions:CLN7 is a rare neurodegenerative disease, the main clinical features of which are epileptic seizures, progressive motor intelligence regression, visual loss, cranial MRI suggesting brain atrophy, and binocular macular degeneration. MFSD8 gene heterozygous mutations c.553G>A (p.V185I) and c.1391C>T (p.A464V) are the genetic etiology of this proband.
