OBJECTIVETo summarize clinical features and diagnosis of Chinese infantile patients with glycogen storage disease type II (GSD II).

METHODSix infant patients with GSD II diagnosed from January 2012 to June 2014 in the Department of Pediatrics, Peking University First Hospital were enrolled into this study. Clinical information of the 6 patients, including clinical manifestation, blood biochemistry, chest X-ray, echocardiogram, electrocardiogram, acid alpha-glucosidase (GAA) activity and GAA gene mutation analysis by direct sequencing of polymerase chain reaction (PCR) product were reviewed.

RESULTOf the 6 patients, five were female and one was male, five of whom were classic infantile type while the other one was atypical. The age of onset ranged from birth to 3-month-old. All patients had varying degrees of generalized muscle weakness, hypotonia and development retardation or retrogression. Other common findings were feeding difficulties in two patients, tongue weakness in two patients, respiratory distress in four patients, macroglossia in one patient, and hepatomegaly in two patients. Left ventricular hypertrophy and cardiomegaly were obvious in all the six patients. All six patients were found to have a enlarged heart in physical examination, and three patients who underwent a chest X-ray examination had an enlarged heart shadow. Four patients who had an echocardiography were found to have myocardial hypertrophy. The electrocardiogram in three patients showed short PR intervals and high voltage. The creatine kinase (CK) levels were three to seven times elevated. The mildest elevated CK was 441 IU/L, and the highest CK level was 1 238 U/L. Assay of GAA enzyme activity in whole blood showed significantly reduced activity (1.3 nmol/ (spot·d) to 2 nmol/(spot·d)) in the patients tested. Gene sequencing in 4 patients showed 8 pathogenic mutations, including 6 missense mutations, one nonsense mutation and one frameshift mutation. The missense mutations were c.998C > A (p.Thr333Lys), c.1280T > C (p.Met427Thr), c.1760T > C (p.Leu587Pro), c.1924G > T (p.Val642Phe), c.2012T > A (p.Met671Lys) and c.2105G > A (p.Arg702His). The nonsense mutation was c2662G > T (p.Glu888X), and the frameshift mutation was c2812_2813delTG (p.Cys938fs). The 5 classic infantile patients died at the age of 7 to 22 months. The atypical infantile patient was 2 years and five months old according to our latest follow up.

CONCLUSIONInfantile GSD II had similar motor manifestations and cardiac involvements, blood biochemical test, imaging findings, enzyme assays, though there were slight differences. The probability of GSD II should be taken into consideration if an infant has both muscular disease and cardiac involvement.

Objective To explore the relationships between the screen time with parent-child relations as well as social ability and behavioral problem in preschool children.Methods A total of 866 children aged 3-6 years old in Dazhou City conducted the sampling survey by adopting the children screen time questionnaire,parent-child relationship self-rating scale and young children's social ability and behavior assessment scale(SCBE-30).The single factor analysis and multinomial Logistic regression method were used to conduct the statistical analysis.Results The surveyed preschool children watching TV every day accounted for 99.31 ％,those playing mobile phones every day accounted for 81.87％ and those using computer accounted for 68.36％s.The average daily screen time at ordinary time was 1.75 h/d,those ≥2 h/d accounted for 16.05％;the average screen time at the weekend was 2.32 h/d,those ≥2 h/d accounted for 46.57％.The univariate analysis showed that the screen time in boy,left behind children,only child,mothers engaging in agriculture of peasant-worker or housewife was longer(P＜0.05);the screen time affected the social ability and behavior problems of children(P＜0.05).The longer the time children spent with their parents every day,the higher the parent-child relationship score(P＜0.05);the screen content affected the parent-child relationship and anxiety withdrawal behavior (P＜0.05).The polynormial regression analysis between the children's screen time with social ability,behavior problems,parent-child relation and contacting screen mode showed that the screen time had the negative effect relation with the social ability and parent-child relation(parents and children questionnaire) score(β=-1.115,-1.728,-1.909,P＜0.05),and had the positive effect relation with the scores of anger attack behavior and anxiety retreat behavior,and individual contacting screen (β=0.982,1.474,0.877,P＜0.05).Conclusion The screen time in preschool children is related with parent-child relation,social ability and behavioral problems.The parental accompany is beneficial to the development of parentchild relations in preschool children.

Objective:To evaluate the effect of intrathecal insulin-like growth factor-1 (IGF-1) on chemotherapy-induced neuropathic pain (NP) in mice.Methods:Forty clean-grade healthy male C57 mice, aged 7-9 weeks, weighing 22-24 g, were divided into 4 groups ( n=10 each) using a random number table method: control group (group C), chemotherapy-induced NP group (group CIPN), low-dose IGF-1 group (group I1) and high-dose IGF-1 group (group I2). In CIPN, I1 and I2 groups, oxaliplatin 5 mg/kg was intraperitoneally injected for 5 consecutive days to establish chemotherapy-induced NP model.Normal saline 0.2 ml was given in group C. After measurement of the pain threshold at 10 days after establishment of the model, IGF-1 0.5 and 1.0 μg were intrathecally injected in group I1 and group I2, respectively.Normal saline 5 μl was intrathecally injected in C and CINP groups.Mechanical withdrawal threshold (MWT) was measured at 3, 5, 8, 10, 11, 13 and 15 days after establishment of the model.After measurement of the pain threshold at 15 days after establishment of the model, the expression of spinal IGF-1, IGF-1receptor (IGF-1R), interleukin (IL)-17A, IL-1β and tumor necrosis factor (TNF)-α was detected, and IGF-1 positive cells were counted using immunofluorescence. Results:Compared with group C, MWT was significantly decreased, the expression of spinal IGF-1 was down-regulated, the count of IGF-1 positive cells was decreased, and expression of IL-17A, IL-1β and TNF-α was up-regulated at 3-25 days after establishment of the model in CINP, I1 and I2 groups ( P<0.05). Compared with group CIPN, MWT was significantly increased at 15 days after establishment of the model in group I1, and MWT was increased, the expression of spinal IGF-1 was up-regulated, the count of IGF-1 positive cells was increased, and expression of IL-17A, IL-1β and TNF-α was down-regulated at 13 and 15 days after establishment of the model in group I2 ( P<0.05). Compared with group I1, the count of IGF-1 positive cells in spinal dorsal horn was increased in group I2 ( P<0.05). There was no significant difference in the expression of spinal IGF-1R among the 4 groups ( P>0.05). Conclusion:Intrathecal IGF-1 can alleviate chemotherapy-induced NP, and the mechanism may be related to inhibiting the inflammatory responses in spinal cord of mice.

Objective: To investigate the genotype and genetic characteristics of the pathogens associated with the epidemic outbreak of acute gastroenteritis(AGE) in Guangyuan city, Sichuan province. Methods: Eighteen stool samples and 15 anal swab samples from 4 AGE outbreaks were collected from Feb 2017 to May 2017. Norovirus (NoV) nucleic acid was detected by Real-time PCR method , and the positive samples were amplified by conventional reverse transcription-polymerase chain reaction (RT-PCR) and nucleotide sequencing. Results: Four AGE outbreaks were all caused by NoV. And 20 (60.6%) samples were positive for NoV GⅡ. Gene sequence comparison and phylogenetic analysis showed that 4 AGE outbreaks were all caused by GⅡ.P16/GⅡ.2 NoV. All the strains of GⅡ.P16/GⅡ.2 NoV shared high homology in nucleotides. One of the outbreaks was caused by GⅡ.P16/GⅡ.2 and GⅡ.P7/GⅡ.14 NoV co-infection. Conclusions The 4 outbreaks of AGE in Guangyuan city, Sichuan province were major caused by GⅡ.P16/GⅡ.2 NoV, meanwhile GⅡ.P16/GⅡ.2 and GⅡ.P7/GⅡ.14 NoV co-infection existed.
