Arts syndrome: a case report and literature review / 中华实用儿科临床杂志

Objective:To investigate the clinical and genetic features of children with Arts syndrome.Methods:The clinical features of a child with Arts syndrome diagnosed in Department of Neurology, Children′s Hospital of Nanjing Medical University were retrospectively analyzed.Relevant literatures about Arts syndromes were reviewed as well.Results:It was a 17-month-old boy with initial symptoms of hearing loss after birth, delayed motor development and early-onset hypotonia.At the age of 15 months old, the boy had respiratory failure due to pneumonia.Electromyographic suggested multiple peripheral neurogenic lesions.Visual evoked potentials were normal.Gene sequencing of PRPS1 of the boy revealed a novel hemizygous missense c. 421C>T (p.P141S) hemizygote missense mutation, and therefore, the boy was diagnosed as Arts syndrome.Motor development improved after rehabilitation treatment.Through literature review, 14 children with Arts syndrome, including 4 genotypes of missense mutations were reviewed in 4 English-published literatures.These cases had similar manifestations with the case reported in this study.Conclusions:Arts syndrome is a rare X-linked recessive inheritant disorder caused by PRPS1 mutations with complex clinical phenotypes.The novel missense mutation c. 421C>T found in this study expands the PRPS1 gene mutation profile.

Noninvasive indicators of indications for antiviral therapy in HBeAg-negative chronic HBV infection patients with alanine aminotransferase ≤40 U/L / 临床肝胆病杂志

Objective To investigate the noninvasive indicators of indications for antiviral therapy in HBeAg-negative chronic hepatitis B virus (HBV) infection patients with alanine aminotransferase (ALT) ≤40 U/L under the guidance of liver pathology. MethodsA retrospective analysis was performed for the clinical data of 377 HBeAg-negative chronic HBV infection patients with ALT ≤40 U/L who were hospitalized in Affiliated Hospital of Yan’an University, from October 2013 to August 2018 and underwent liver biopsy, among whom the patients with inflammatory activity ＜A2 and fibrosis stage ＜F2 were enrolled as non-antiviral therapy group(n=266), and the patients with inflammatory activity ≥A2 or fibrosis stage ≥F2 were enrolled as antiviral therapy group(n=111). The chi-square test was used for comparison of categorical data between two groups; the t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; univariate and multivariate binary logistic regression analyses were used to screen out the influencing factors for the initiation of antiviral therapy; the receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficiency of each indicator in determining the need for antiviral therapy in HBeAg-negative chronic HBV infection patients with ALT ≤40 U/L. ResultsOf all 377 patients, 266 (70.6%) did not need antiviral therapy for the time being, and 111 (29.4%) had marked liver damage and thus needed active antiviral therapy. The multivariate analysis showed that liver stiffness measurement (LSM) (odds ratio ［HR］=2.003, 95% confidence interval ［CI］: 1.647-2.437, P＜005), HBsAg (HR=1.563, 95% CI: 1.110-2.200, P＜0.05), HBV DNA (HR=1.519, 95% CI: 1173-1.966, P＜0.05), and albumin (HR=0.939, 95% CI: 0.884-0.998, P＜0.05) were independent influencing factors for the initiation of antiviral therapy. The ROC curve analysis showed that the area under the ROC curve (AUC) was 0.749 (95% CI: 0.699-0799) for LSM, 0642 (95% CI: 0.586-0.699) for HBV DNA, and 0.565 (95% CI: 0.507-0.623) for HBsAg, and the combination of LSM, HBV DNA, and HBsAg had a larger AUC of 0.779 (95% CI: 0.732-0.827). ConclusionThe levels of LSM, HBV DNA, and HBsAg have a reference value in determining the initiation of antiviral therapy in HBeAg-negative chronic HBV infection patients with ALT≤40 U/L.

Objective:To investigate the clinical and genetic characteristics of peroxisome D-bifunctional protein deficiency (PDBPD) associated with HSD17B4 mutation. Methods:The clinical and genetic characteristics of 2 cases of PDBPD in August 2020, at Children′s Hospital Affiliated to Nanjing Medical University caused by HSD17B4 gene mutation were retrospectively analyzed. Results:Male proband and his sister suffered from neonatal epilepsy, psychomotor development disorders, ataxia, myasthenia, hearing impairment, and foot deformity.The very long chain fatty acids in serum were normal, and brain magnetic resonance imaging (MRI) showed bilateral cerebellar hemisphere atrophy.Electromyography suggested changes in the myoelectricity of multiple peripheral neurogenic lesions.Auditory evoked potential displayed severe bilateral sensorineural hearing loss.Exome sequencing identified compound heterozygous mutations (c.1171G > C, c.686-2A>T) in HSD17B4.The clinical diagnosis was PDBPD, aged 8 and 14 years, respectively. Conclusions:Two cases of HSD17B4 mutation-induced PDBPD were first reported in Chinese mainland, which was in line with its typical clinical manifestations.The newly discovered c. 1171G> C and c. 686-2A>T mutations enriched the HSD17B4 mutation spectrum.

Comparison of emotional and behavioral problems between preschool firstborn children across the transition to siblinghood and the only children / 中国学校卫生

Objective@#To compare the emotional and behavioral characteristics of preschool firstborn children across the transition to siblinghood with the only children in a district of Chongqing.@*Methods@#Data were derived from a cohort study on firstborn children transition to siblinghood. Totally 882 firstborn children (3.58±1.25) years old and 329 only children (3.98±1.02) years old were recruited from two hospitals and 19 kindergartens in a district of Chongqing, respectively. Their mothers filled out the parental version of Child Behavior Checklist (CBCL) and self designed questionnaire.@*Results@#The overall scores of emotional and behavioral problems of firstborn children and only children were (25.17±18.82) and (31.75±18.64). The results of rank sum test showed that the scores of the firstborn children in all dimensions, internalizing and externalizing behavior problems and overall emotional and behavioral problems were lower than those of the only children ( P <0.05). Chi square test results showed that the detection rates of internalizing, externalizing and overall emotional behavior problems in only children(12.77%, 13.07%, 14.59%) were higher than those in firstborn children(8.28%, 8.28%,8.16%) ( χ 2=5.62, 6.36, 11.09, P <0.05). Multiple linear regression showed that after adjusting for age, gender, family economic pressure, temperament type of children, family atmosphere and family type, the scores of internalizing problems, externalizing problems and overall problems of the only children were still higher than those of the firstborn children ( B =1.54, 2.32, 6.81, P <0.05).@*Conclusion@#The firstborn children across the transition to siblinghood show less emotional and behavioral problems than the only children, and the scores and detection rates of all types of emotional and behavioral problems of the firstborn children are lower than those of the only children.

The high frequency ultrasonographic features of rectus diastasis and their relationships with the modes of delivery in postpartum women / 中华超声影像学杂志

Objective:To investigate the multi-sites high frequency ultrasound features of rectus diastasis (RD) in early postpartum women and their relationships with different delivery modes.Methods:Total of 571 primiparas who gave birth in the Obstetrics and Gynecology Hospital Affiliated to Zhejiang University Medical College from March to May 2020 and underwent 6-week postpartum examination were chosen, they were divided into vaginal delivery group (336 cases) and the cesarean section group (235 cases). The inter-rectus distance(IRD) of five loci (umbilical on 4.5 cm, umbilical on 3 cm, umbilical edge, edge of umbilical, umbilical down 3 cm) at resting state and two loci (umbilical edge, edge of umbilical) at curling state as well as the rectus thickness on the right side of umbilical level were observed by high frequency ultrasound. The impacts of the two delivery modes on IRD at each site and the changes of IRD under the two conditions were analyzed. Spearman correlation analysis was used to evaluate the correlation between the thickness of rectus abdominis and IRD at each site.Results:The incidence of early postpartum RD was 79.7% (455/571), most of which occurring at 3 cm above the umbilicus and the umbilicus levels. At resting state, the IRDs at the 5 loci of vaginal delivery group were (1.62±0.79)cm, (2.03±0.84)cm, (2.65±0.94)cm, (2.09±0.93)cm, and 0.54(0.00, 1.13)cm respectively, while the IRDs at 5 loci of the cesarean section group were (1.75±0.85)cm, (2.26±0.99)cm, (2.99±1.14)cm, (2.57±1.21)cm, and 1.00(0.41, 1.59)cm, with statistical differences at all the levels between groups ( P<0.05). Under the curling state, the IRDs at the 2 loci of vaginal delivery group were (2.10±0.84)cm and (1.66±0.86)cm respectively, while the IRDs at the 2 loci of cesarean section group were (2.28±0.87)cm and (1.91±0.87)cm, with statistical differences between groups( P<0.05). The incidences of increased IRD when compared between resting and curling states at the upper and lower umbilicus in the vaginal delivery group were 16.1% and 26.5%, with 17.4% and 20.4% in the cesarean section group. At the resting state, there was a significant difference in the thickness of rectus abdominis between the vaginal delivery and cesarean section groups [(0.74±0.12)cm vs (0.67±0.12)cm, P<0.05]. At the curling state, the difference between two groups was statistically significant [(1.11±0.23)cm vs (0.99±0.22)cm, P<0.05]. The thickness of rectus abdominis was negatively correlated with IRD(all the 5 loci at resting state, rs=-0.116, -0.140, -0.185, -0.143, -0.144, all P<0.01; and the upper umbilical loci at curling state, rs=-0.091, P<0.05). There was no significant correlation between the thickness of rectus abdominis and IRD at the lower umbilical edge at the curling state ( P>0.05). Conclusions:High frequency ultrasound can evaluate the morphological characteristics of the abdominal rectus muscle in early postpartum stage. Compared with vaginal delivery, rectus abdominis thickness, the IRD is larger in cesarean section primiparas, but less affected by the curling state.

Current status of the diagnosis and treatment of chronic hepatitis B virus infection with immune control / 临床肝胆病杂志

Patients with chronic hepatitis B virus (HBV) infection with immune control generally have no or little liver damage, with a low incidence rate of adverse events, and spontaneous HBsAg seroclearance may occur in some patients. Most scholars do not recommend antiviral therapy for such patients in China and foreign countries. However, with the gradual aging of chronic HBV infection, patients with immune control are also faced with disease progression and the development of liver cirrhosis or liver cancer. This article introduces the clinical significance of appropriate timing of antiviral therapy for the prognosis of patients with chronic HBV infection with immune control.

Risk factors for hepatitis B virus-related hepatocellular carcinoma / 临床肝胆病杂志

At present, hepatitis B virus (HBV) infection is recognized as an important risk factor for hepatocellular carcinoma (HCC) in the world; however, during the development and progression of hepatitis B, liver cirrhosis, and liver cancer, other factors may promote the development of HCC independently or synergistically with HBV, such as sex, age, family history, alanine aminotransferase/aspartate aminotransferase, smoking and drinking history, metabolic syndrome, and HCV or HIV infection. This article reviews the research advances in the risk factors associated with HCC.

The results of local spatial analysis showed that the clustering regions of hypertension patients were in northeast and eastern parts of China. The results of spatial regression analysis showed that males,age of 80 years and above and overweight were the main risk factors for hypertension（all P<0.05）,which had greater influence on the middle part of China,north and northeast of China,and the east and north of China,respectively.@*Conclusion @#Males,age of 80 years and above and overweight were the main risk factors for hypertension in middle-aged and elderly population in China. The main prevention and control areas of hypertension were eastern and northeast China.

Research advances in the diagnosis and treatment of patients in the immune tolerance stage of chronic hepatitis B virus infection / 临床肝胆病杂志

Patients in the immune tolerance stage of chronic hepatitis B virus (HBV) infection are in a state of high viral replication and low inflammation in the liver, and they often have no disease progression. Therefore, antiviral therapy is not recommended in related guidelines. Recent studies have found that the patients in the immune tolerance stage have immune response and liver injury, which is a risk factor for liver cancer, and therefore, antiviral therapy should be actively initiated to prevent disease progression. This article summarizes the research advances in the diagnosis and treatment of patients in the immune tolerance stage of chronic HBV infection and points out that there are still controversies over the application of antiviral therapy in such patients. Appropriate timing of antiviral therapy has a great significance in improving patients’ prognosis and reducing their economic burden.
