Objective:To report a SPTLC2 gene mutation in a family with a phenotype of Charcot-Marie-Tooth disease.Methods:To screen the family of patients with pathogenic mutations of SPTLC2 gene from the database of hereditary peripheral neuropathy in the Department of Neurology, Peking University First Hospital, and to collect their clinical data, peripheral nerve conduction examination, nerve ultrasound examination, pathological examination of the peroneal nerve and whole exome sequencing results of prohand.Results:One family was screened, the proband was a 16-year-old female with 4 years of sensory loss and anhidrosis of both lower limbs and 16 months of walking difficulty who admitted to Peking University First Hospital in January 2022. Physical examination showed sensory loss, dry skin and weakness in distal limbs. Her father had numbness and dry skin in the distal lower limbs from childhood,weakness and atrophy of his lower limbs in adulthood. He died at age of 52 years old. The nerve conduction study revealed no action potentials of the sensory and motor nerves of the lower limbs in the proband. The amplitude of the compound muscle action potential of the motor conduction of the bilateral ulnar nerve and median nerve decreased, and the nerve conduction velocity of the bilateral median nerve were 32 m/s and 24 m/s. Neurosonography showed thickening of peripheral nerves. Sural biopsy revealed severe loss of myelinated and unmyelinated nerve fibers with onion bulbs formation. SPTLC2 gene showed a known heterozygous p.G435V mutation. The lower limb weakness was improved after oral L-serine.Conclusions:SPTLC2 gene mutation can lead to an intermediate Charcot-Marie-Tooth disease phenotype. L-serine can improve the limb weakness.

Objective:To study the prevalence and clinical characteristics of hepatitis D patients.Methods:A total of 832 144 HBsAg positive persons who were from infectious department of Southwest Hospital Affiliated to Army Military Medical University were screened from January 1, 2010 to December 31, 2020. A total of 13 585 subjects completed relevant Hepatitis Delta virus (HDV) biomarker tests, 157 HDV patients were evaluated. The mean age was 53 ± 13 years, with a range of 22-85 years. The majority of these subjects were male. The prevalence, clinical characteristics, the outcome of 28 days follow-up and the influencing factors of the outcome were analyzed.Results:In recent 10 years, the screening rate related to hepatitis D was only 1.6% (13 585/832 144), and the screening rate was the highest in 2011, up to 4.13% (962/23 289); The positive rate of screening was only 1.17% (157/13 346). In 2012, the positive rate of screening was the highest, up to 3.56% (58/1627). In Southwest Hospital, the source of disease was 66.24% (104/157) in Chongqing, 22.93% (36/157) in Sichuan, 8.28% (13/157) in Guizhou, 1.27% (2/157) in Yunnan, and 0.64% (1/157) in each of Jiangxi and Tibet. Of 157 patients, 29 (18.47%) had non-cirrhotic with chronic low bilirubin hepatitis, 23.57% (37/157) was non-cirrhotic with chronic high bilirubin hepatitis, 28.66% (45/157) had acute-on-chronic liver failure (ACLF), 27.39% (42/157) had compensated cirrhosis or decompensated cirrhosis, and 1.91% (3/157) had primary hepatocellular carcinoma. The incidence of disease progression was 48.89% (22/48) of chronic-on-acute liver failure>33.33%(1/3) of primary hepatocellular carcinoma>25.58%(11/43) of compensated or decompensated cirrhosis>18.92%(7/37) of non-cirrhotic with chronic high bilirubin hepatitis>6.90%(2/29) of non-cirrhotic with chronic low bilirubin hepatitis ( P<0.05). Among them, 7.64%(12/157) had hepatic encephalopathy, and the rate of disease progression was 83.33%(10/12) ( P<0.05); 3.82% (6/157) of them had combined with other hepatophilic viruses including hepatitis C virus (HCV), Epstein-barr virus, (EBV), Cytomegalovirus (CMV) infections. Logistic regression analysis showed that old age, complication with hepatic encephalopathy, hyperbilirubinemia and prolonged coagulation time were independent risk factors affecting the outcome of hepatitis D. Conclusions:In recent 10 years, the screening rate of hepatitis D is low and the positive rate is not high. It should be noted that HDV infection can accelerate the progress of hepatitis and increase the risk of adverse liver outcomes.

Chronic liver diseases in children greatly affect their growth and development and quality of life in future.There are many causes of chronic liver diseases in children,and such causes,diet,and treatment guidance are closely associated with prognosis.This article discusses the guidance and follow-up of common chronic liver diseases in children,such as infantile cholestatic liver disease,chronic hepatitis B,hepatolenticular degeneration,and nonalcoholic fatter liver disease,in order to deepen the understanding of these diseases among patients,raise the awareness of follow-up in medical staff,and improve the cure rate of liver diseases with different causes and children's quality of life.

Objective To report the clinical and peripheral neuropathological findings in two patients with autosomal recessive Charcot-Marie-Tooth disease 2K(AR-CMT2K).Methods Case one was a nine year-old girl.She had distal weakness of lower limbs for six years, with calf atrophy and contracture of Achilles tendon for three years.Case two was an eight year-old boy.He had distal weakness of lower limbs with contracture of Achilles tendon and calf muscle atrophy for three years, and proximal weakness of low limbs for two years.The motor nerve conduction velocities in median nerves were 48.1 m/s in case one and 47.6 m/s in case two.The compound motor action potential amplitude of median nerves decreased by 46% in case one and 69% in case two.Sural nerve biopsies and gene targeted next-generation sequencing were performed in both patients.Results Density of myelinated fibers was 8 407/mm2 in case one and 7 714/mm2 in case two.The ratio of myelinated fibers with diameter over 8 μm was 2.6% in case one and 0 in case two.Both patients had small regenerating cluster of myelinated fibers.Thin myelinated fibers appeared in case one.In case two, atypical onion bulb formations with focal folded myelin appeared, and electromicroscopy revealed mitochondrial aggregate in axons.Compound heterozygous mutations of ganglioside-induced differentiation associated protein 1 gene were detected in both patients, including c.767A>G(p.H256R) and c.466G>A (p.A156T) in case one and c.767A>G and 845G>A(p.R282H) in case two.Conclusions Contracture of Achilles tendon may appear in early childhood of AR-CMT2K patients.The main pathological changes in sural nerve are loss of large myelinated fibers, mitochondrial aggregate in axons and myelin abnormalities.

Objective To analyze the normal reference values of left ventricular longitudinal peak systolic strain (LS) and strain rate (LSr) by two-dimensional speckle tracking imaging (2D-STI) in healthy children at different ages.Methods Clinical ultrasound data of 330 healthy children who taking physical examination in our hospital from September 2015 to November 2016 were collected and retrospectively.They were divided into 7 groups according to their ages,that is,neonate group (0 to 28 days old),infant group (28 days to 1 year old),toddle group (1 to 3 years old),pre-school group (3 to 6 years old),school age group (6 to 9 years old),pre-adolescence group (9 to 13 years old) and adolescence group (13 to 18 years old).2D-STI was performed in the 3 apical projections of left ventricle (LV).The regional peak systolic longitudinal strain and strain rate of LV were measured.Results ① Significant differences were found in the LS and LSr values from 6 segments of the same wall (P ＜ 0.05),and the LS and LSr values were gradually increased from basal segment to apical segment.②There were no significant differences in the LS,LSr and global LS (GLS) values of 18 segments between sexes (P ＞ 0.05).③ Except the basal segments of posterior wall,inferior wall and posterior septum,LS value was gradually elevated with the increase of age (LS ＜LSinfant ＜ LStoddler,pre-shool and school age ＜ LSpre-adolescence and adolescence),So was GLS value.④LS in 18 segments had a positive correlation with age,and the value of apical segment in lateral wall was most remarkably correlated (r =0.551,P ＜0.01);Regional LS had a negative correlation with heart rate,and that of middle segment in lateral wall was the most apparent (r =-0.625,P ＜ 0.01);GLS was positively influenced by age (r =0.665,P ＜ 0.01) and negatively affected by heart rate (r =-0.625,P ＜ 0.01).⑤The heterogeneities were found in the correlations of regional LSr with age and heart rate in segments and in the LSr among different age groups.Conclusion Normal reference values of LV peak LS and LSr are established for healthy children at different ages,and they possess their own characteristics.
