One unusual human G3P[3] group A rotavirus (RVA) strain M2-102 was identified in stool sample collected from a child with diarrhea in Guangxi Province, China in 2014. It is well known that G3P[3] is a genotype commonly identified in feline and canine RVAs. However, the preliminary phylogenetic analyses of the VP7 and VP4 genes of strain M2-102 indicated that these two genes were closely related to bat RVA strain MYAS33 and simian strain RRV, respectively, whereas both clustered distantly to feline/canine-like RVA strains. In this study, full genome sequencing and molecular analyses were conducted to obtain the true origin of strain M2-102. It was revealed that strain RVA/Human-wt/CHN/M2-102/2014/G3P[3] exhibited a G3-P[3]-I3-R3-C3-M3-A9-N3-T3-E3-H6 genotype constellation for VP7-VP4-VP6-VP1-VP2-VP3-NSP1-NSP2-NSP3-NSP4-NSP5 genes. Phylogenetic analyses revealed that 5 genes (VP7, VP1, VP2, NSP2 and NSP3) from strain M2-102 were closely related to those of bat strain MYAS33 from Yunnan Province which was thought a true bat RVA strain rather than a virus transmitted between species, while another 5 genes (VP4, VP3, NSP1, NSP4 and NSP5) clustered closely with those of simian strain RRV, yet the VP6 gene was closely related to that of human G3P[9] strain AU-1 and AU-1-like RVAs. The epidemiological data indicated that the child infected with M2-102 came from a countryside village, located in Dong Autonomous County of Sanjiang (subtropical hilly wooded area), Liuzhou city in Guangxi Province which might provide natural environment for reassortment events occurring among animal and human RVAs. Therefore, the data suggest that human strain M2-102 might originate from multiple reassortment events among bat, simian and human AU-1-like RVAs, yet it is not clear whether the genomic backbone based on bat MYAS33 (5 genes) and simian RRV (5 genes) like rotaviruses had been obtained through reassortment before being transmitted to the human. This is the first report on whole genome analysis of human G3P[3] RVA from China.

Objective To investigate clinical features and risk factors for recurrent syncope in children with orthostatic intolerance.Methods Patients with orthostatic intolerance and syncope admitted in the Second Hospital of Lanzhou University from January 2014 to June 2015 were retrospectively analyzed by using t test,Chi -square test,and Fisher′s exact probability method.According to frequency of syncope,all cases were divided into 2 groups,the occasio-nal syncope group and the recurrent syncope group.All risk factors including age,gender,body mass index(BMI),in-ducement,the history of motion sickness,family history,syncope -related injuries,performance of head -up tilt table test,and outcomes of head -up tilt table test were studied statistically and compared within 2 different groups.Results A total of 83 cases were enrolled in this study.Among these children,33 cases(39.76%)were assigned as occasio-nal syncope group,in which 17 cases were male and 16 cases were female and the age ranged from 6 to 18 years with the average age of (9.70 ±2.87)years;50 cases(60.24%)were assigned as recurrent syncope group,in which 27 ca-ses were male and 23 cases were female and the age ranged from 6 to 18 years with the average age of (11.24 ±2.83) years.Of all the investigated risk factors,the BMI and the history of motion sickness were significantly different between 2 groups[(18.84 ±3.49)kg/m2 vs (18.16 ±3.68)kg/m2 ,t =4.82,P =0.001;39.39%(13 /33 cases)vs 70.00%(35 /50 cases),χ2 =7.64,P =0.006].No significant difference was found in age distribution(6 -9 years,10 -14 years,15 -18 years)between 2 groups(P =0.428).There were no significant differences in gender (male /female), family history,or syncope -related injuries between 2 groups[17 /16 cases vs 27 /23 cases;3.03%(1 /33 cases)vs 10.00%(5 /50 cases);15.15%(5 /33 cases)vs 20.00%(10 /50 cases),all P >0.05].And no significant difference was found in inducement (prolonged standing,body posture change,emotional stress/emotional stimuli,muggy environ-ment,movement)between 2 groups [78.79% (23 /33 cases)vs 72.00% (36 /50 cases);9.09% (3 /33 cases)vs 14.00%(7 /50 cases);3.03%(1 /33 cases)vs 6.00%(3 /50 cases);12.12% (4 /33 cases)vs 10.00% (5 /50 cases);3.03%(1 /33 cases)and 12.00%(6 /50 cases),all P >0.05].And performances of head -up tilt table test (blurred vision/blacked out,nausea/vomiting,sweating,dizzy/headache,palpation,anhelation /chest tightness,hot, weak)between 2 groups showed no significant differences[18.18%(6 /33 cases)vs 12.00%(6 /50 cases);36.36%(12 /33 cases)vs 50.00%(25 /50 cases);24.24%(8 /33 cases)vs 26.00%(13 /50 cases);51.52%(17 /33 cases) vs 58.00%(29 /50 cases);6.06%(2 /33 cases)vs 16.00%(8 /50 cases);27.27%(9 /33 cases)vs 22.00%(11 /33 cases);33.33%(11 /33 cases)vs 32.00%(16 /50 cases);12.12%(4 /33 cases)vs 16.00%(8 /50 cases),all P >0.05].Also there were no significant differences in outcomes of head -up tilt table test between 2 groups(P =0.589). Conclusions The risk factors for recurrent syncope in children with orthostatic intolerance were low BMI and the his-tory of motion sickness for such children,and more positive and effective clinical intervention can improve the living quality of children with orthostatic intolerance to some extent.

Background/Aims: The effect of physical activity on the relationship between dietary fiber intake and constipation has not been comprehensively studied.This study aims to explore the impact of physical activity. Methods: Data were obtained from 3 cycles of the National Health and Nutrition Examination Survey (NHANES) 2005-2010 and included a total of 13 941 participants aged ≥ 20 years. Multiple logistic regression analysis was used to investigate the independent associationbetween dietary fiber and constipation. Interaction analysis was also performed to analyze the relationship between dietary fiber and constipation in different physical activity groups. Results: Among non-active participants, dietary fiber intake did not associate with stool consistency (OR, 1.02; 95% CI, 0.98-1.05; P = 0.407). For physically active participants, 1-gram unit increase in dietary fiber intake reduced the risk of stool consistency by 3% (OR, 0.97; 95% CI, 0.94-0.99; P = 0.020). Moreover, the relationship between dietary fiber intake and stool consistency was significantly different for groups with different levels of physical activity (P interaction = 0.044). However, dietary fiber intake was not related to stool frequency among non-active participants (OR, 0.99; 95% CI, 0.94-1.05; P = 0.767) nor physically active participants (OR, 1.01; 95% CI, 0.97-1.04; P = 0.751). Conclusions Increasing dietary fiber intake was associated with stool consistency-related constipation among physically active participants, but not among non-active participants. However, increasing dietary fiber intake is not significantly associated with stool frequency in different physical activity groups.

Objective:To analyze the clinical features and CYP17A1 gene mutation of 17α-hydroxylase/17, 20-lyase deficiency (17OHD). Methods:The clinical data, laboratory examination and genetic results of 6 children with 17OHD in the Department of Endocrinology, Children′s Hospital Affiliated to Capital Institute of Pediatrics from March 2014 to December 2019 were enrolled and analyzed retrospectively.Meanwhile, the clinical types of all congenital adrenocortical hyperplasia (CAH) patients were calculated and then the incidence of 17OHD was calculated.Results:The 6 cases were from 5 families, and the age at diagnosis was ranged from 1 year and 6 months to 15 years old, in which 2 cases were 46, XX and 4 cases were 46, XY.Their gender were all female.Three cases presented with hypertension (50.0%), 4 cases with hypokalemia (66.7%), and 1 case with labia mass (16.7%). The gonad developed into a testis in patients with 46, XY, and patients with 46, XX had ovarian hypoplasia.The laboratory tests revealed an decrease in the cortisol at 8 AM in all cases, ranging from 0.62 to 5.93 mg/L.Five cases displayed an increase in adrenocorticotropic hormone (ACTH) in the range of 84-271 ng/L, and 1 patient with normal ACTH (58 ng/L) had a peak cortisol of 1.75 mg/L after the ACTH challenge test.Elevated progesterone was detected in 6 patients with a normal 17 hydroxyprogesterone level.Further results proved low levels of testosterone and estradiol, and high levels of luteinizing hormone (LH), and follicle stimulating hormone (FSH). CT scan showed mild adrenal hyperplasia in all cases.Among 114 CAH patients during the same period, the incidence of 17OHD came second at 5.3%.The CYP17A1 gene mutation results indicated that 2 unrelated patients were homozygous mutation for p. Y329fs (c.985_987delTACinsAA), 2 siblings were compound heterozygous mutations for p. Y329fs and exon 1-7 deletion, 1 patient was compound heterozygous mutations of p. Y329fs and p. R416C (c.1246C>T), and 1 patient was homozygous mutations for p. L465P (c.1394T> C), which was first reported in China. Conclusions:17OHD is not rare in CAH.Female children with hypokalemia, hypertension, and hypogonadism can lead to diagnostic suspicion of 17OHD.The p. Y329fs mutation in Chinese 17OHD children is a hotspot.The p. L465P (c.1394T>C) mutation is a new mutation in China and it could enrich the mutant spectrum of CYP17A1 gene in China.
