Objective:To compare the effectiveness of two types of robotic training in improving the lower extremity motor functioning of children with spastic cerebral palsy (SCP).Methods:Twenty-eight children with SCP were randomly divided into a control group and an experimental group, each of 14. Both groups received conventional exercise therapy, paraffin therapy, neuromuscular electrical stimulation, and massage. Both also performed 30 minutes of gait training five days a week for eight weeks assisted by either a Lokomat or a Relink lower limb rehabilitation robot. Before and after the treatment, both groups were evaluated using the Gross Motor Function Measure (GMFM), the Pediatric Balance Scale (PBS), the Modified Tardieu Scale (MTS), the six-minute walk test (6MWT), the Physiological Cost Index (PCI) and their self-selected walking speed (SWS).Results:Significant improvement in all of the measurements were observed in both groups. After the treatment, there were no significant differences between the two group in the average GMFM (section D and E) or PBS scores. The average MTS R1 and R2, SWS, 6MWT and PCI results of the experimental group were, however, significantly better than those of the control group.Conclusion:Applying either the Lokomat or Relink robot in lower extremity rehabilitation improves the lower extremity motor function of children with grade II-III SCP. The Relink robot is the more effective in improving triceps surae spasm and walking ability.

OBJECTIVE:
To analyze the clinical phenotype and genetic characteristics of a child with Hereditary spastic paraplegia (HSP).
METHODS:
A child with HSP who was admitted to the Third Affiliated Hospital of Zhengzhou University on August 10, 2020 due to discovery of tiptoeing for 2 years was selected as the study subject, and relevant clinical data was collected. Peripheral blood samples of the child and her parents were collected for the extraction of genomic DNA. And trio-whole exome sequencing (trio-WES) was carried out. Candidate variants were verified by Sanger sequencing. Bioinformatic software was used to analyze the conservation of variant sites.
RESULTS:
The child was a 2-year-and-10-month-old female with clinical manifestations including increased muscle tone of lower limbs, pointed feet, and cognitive language delay. Trio-WES results showed that she had harbored compound heterozygous variants of c.865C>T (p.Gln289*) and c.1126G>A (p.Glu376Lys) of the CYP2U1 gene. And the corresponding amino acid for c.1126G>A (p.Glu376Lys) is highly conserved among various species. Based on guidelines from the American College of Medical Genetics and Genomics, the c.865C>T was predicted as a pathogenic variant (PVS1+PM2_Supporting), and c.1126G>A was rated as a variant of uncertain significance (PM2_Supporting+PM3+PP3).
CONCLUSION
The child was diagnosed with HSP type 56 due to compound variants of the CYP2U1 gene. Above findings have enriched the mutation spectrum of the CYP2U1 gene.

ObjectiveTo investigate the association between spontaneous portosystemic shunt (SPSS) and hepatorenal syndrome (HRS) in patients with liver cirrhosis. MethodsA retrospective analysis was performed for 93 patients with SPSS from Dezhou Hospital, Qilu Hospital of Shandong University, from January 2015 to January 2022, and the patients were followed up for 12 months with the onset of HRS as the observation endpoint. According to the presence or absence of HRS, the 93 patients with SPSS were divided into HRS group with 38 patients (40.86%) and non-HRS group with 55 patients (59.14%), and the two groups were compared in terms of clinical data, laboratory data, complication, and shunt diameter. Based on the maximum shunt vein diameter of 1.5 cm, the 93 patients with SPSS were divided into high shunt group with 52 patients (55.91%) and low shunt group with 41 patients (44.09%), and with the onset of HRS as the observation endpoint, the two groups were compared in terms of the incidence rate of HRS and survival time curve. The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance between two groups, and the chi-square test was used for comparison of categorical data between two groups. The receiver operating characteristic (ROC) curve was used to predict cut-off values, the Kaplan-Meier curve was used for comparison of survival time, and the Log-rank test was used to compare the differences in survival curves. The multivariate Cox regression analysis was used to investigate risk factors. ResultsCompared with the non-HRS group, the HRS group had significant increases in Child-Pugh score, Child-Pugh class, MELD score, serum creatinine, blood urea nitrogen, alanine aminotransferase, aspartate aminotransferase, maximum shunt vein diameter, the incidence rates of hepatic encephalopathy and spontaneous bacterial peritonitis, and the degree of ascites, as well as significant reductions in main portal vein diameter, serum sodium and albumin (all P<0.05). Compared with the low shunt group, the high shunt group had a significant increase in the incidence rate of HRS (51.92% vs 26.83%, χ²=5.974, P=0.015) and a significant reduction in the time to the onset of HRS (Log-rank P=0.033). A maximum shunt vein diameter of >1.5 cm (hazard ratio [HR]=1.123, 95% confidence interval [CI]: 1.041 — 1.211, P=0.003), an increase in MELD score (HR=1.205, 95%CI: 1.076 — 1.437, P=0.039), a reduction in serum albumin (HR=0.890, 95%CI: 0.814 — 0.974, P=0.011), an increase in the degree of ascites (HR=2.099, 95%CI: 1.066 — 4.130, P=0.032), and spontaneous bacterial peritonitis (HR=2.259, 95%CI: 1.020 — 5.003, P=0.045) were independent risk factors for the onset of HRS in SPSS patients. ConclusionThere is an association between SPSS and HRS, and shunt diameter >1.5 cm was an independent risk factor for HRS in SPSS patients, which should be taken seriously and require early intervention in clinical practice.

Objective:To investigate the characteristics of resting energy expenditure (REE) in children with cerebral palsy (CP) graded with different levels of Gross Motor Function Classification System (GMFCS), and to evaluate the accuracy and association of commonly used REE prediction formulas in children with CP.Methods:It was a retrospective study involving 36 children with CP aged 24-144 months who visited the Third Affiliated Hospital of Zhengzhou University between September 2021 and August 2022.REE was measured by the indirect calorimetry.Based on the GMFCS, children with CP were divided into grade Ⅰ-Ⅱ group (20 cases), grade Ⅲ group (6 cases) and grade Ⅳ-Ⅴ group(10 cases). During the same period, 11 age-matched healthy children were included in control group.The measured REE (MREE) between children with CP and healthy controls was compared.Predicted REE (PREE) calculated by the Harris-Benedict, WHO, Schofield-W, Schofield-WH and Oxford prediction formulas were compared with MREE in children for their consistency and correlation.Independent samples were analyzed using t-test or Mann- Whitney U test, and categorical data were analyzed using Chi- square test.Using paired t-test and Pearson linear correlation analysis to analyze the correlation between MREE and PREE.The accuracy of PREE values calculated by different formulas was assessed using the root mean square error. Results:The MREE in control group and children with CP were (952.18±270.56) kcal/d and (801.81±201.89) kcal/d, respectively.There was no significant difference in the MREE between grade Ⅰ-Ⅱ group versus control group[(868.30±194.81) kcal/d vs.(952.18±270.56) kcal/d, P>0.05], and grade Ⅲ group versus control group [(813.17±192.48) kcal/d vs.(952.18±270.56) kcal/d, P>0.05]. The MREE was significantly lower in grade Ⅳ-Ⅴ group than that of control group [666.00(513.50, 775.50) kcal/d vs.(952.18±270.56) kcal/d, P=0.011]. There were no significant difference between MREE and PREEs calculated by Harris-Benedict, WHO, Schofield-W, Schofield-WH, and Oxford (all P>0.05). The correct classification fraction calculated by the 5 formulas were 33.3%, 47.2%, 41.7%, 47.2%, and 41.7%, respectively.The r values of the consistency of PREE calculated by the 5 formulas were 0.585, 0.700, 0.703, 0.712, and 0.701, respectively.The Blande-Altman Limits of Agreement were (-297.77, 359.22), (-245.60, 326.94), (-250.62, 316.05), (-242.22, 177.36) and (-241.28, 325.81), respectively.The clinically acceptable range was -80.18 to 80.18 kcal/d.The root mean square error were 168.09 kcal/d, 149.64 kcal/d, 146.24 kcal/d, 144.23 kcal/d and 148.77 kcal/d, respectively. Conclusions:The MREE values decreased significantly in children with CP classified as CMFCS grade Ⅳ and Ⅴ.When REE cannot be regularly monitored by indirect calorimetry to develop nutritional support programs, children with CP may be prioritized to estimate REE using the prediction formula of Schofield-WH.
