Children aerophagia is a relatively rare functional gastrointestinal disease.Its main clinical manifestations are swallowing air,chronic bloating,belching and increased anal exhaust.Since lack of understanding of children aerophagia in pediatricians,it can be very easily missed or misdiagnosed in clinic.Understanding of the research status about children aerophagia means to pediatric clinical guidance.This review summarizes the causes,clinical manifestation,diagnosis and treatment of children aerophagia.

Objective To explore the clinical value of 13C-methacetin breath test for the assessment of liver disorder and to analyze its predictive value to the severity of liver function injury in children.Methods Eighteen healthy children served as healthy control group,and 40 patients with different etiology and severity served as experimental group,and then the latter were divided into 2 subgroups,28 patients in Child-Pugh classification A,and 12 cases in below B(11 cases in B and 1 case in C).An oral dose of 2 mg/kg tracer 13C-methacetin was administered to each subject for the 13 C-methacetin breath test.At the same time,serum liver function markers including serum transaminase,bilirubin,albumin and prothrombin time were measured.The acquired data were analyzed by SPSS 17.0 software.Results (1) Metabolisation velocity (MV) max30 and cumulated dose (CUM) 120 in experimental group (46.64 ± 27.93,59.29 ± 30.73) were much lower than those of the healthy control group(73.56 ± 26.03,102.97 ± 41.80) (t =2.450,3.165,all P ＜0.05);(2) MVmax30 and CUM120 were closely correlated with the liver function markers of albumin,total bilirubin,direct bilirubin,prothrombin time (P ＜ 0.05);(3) MVmax30 and CUM120 could predict liver diseases in children,especially the CUM120.With CUM120 =85.80 as a cut-off value to predict liver diseases,the Youden index was 0.578 at its maximum,and the sensitivity and specificity were 77.8％ and 80.0％;(4) Compared with the Child-Pugh classification A,the CUM120 in Child-Pugh classification B and lower B was significantly lower(P ＜ 0.001);(5) CUM120 could predict the severity of liver diseases.With CUM120 =56.15 as a cut off value to predict the severity of liver diseases,the Youden index was 0.857 at its maximum,and the sensitivity and specificity were 85.7％ and 100.0％.Conclusion 13C-methacetin breath test index of CUM120 could predict liver diseases in children and the severity of liver function.

Objective To investigate the clinical characteristics of aerophagia in children,and to evaluate the effect of 24 hours esophageal multichannel intraluminal impedance monitoring in diagnosis of aerophagia.Methods The clinical data of 30 children with aerophagia hospitalized in Department of Digestive Disease,Nanjing Children's Hospital Affiliated to Nanjing Medical University from July 2005 to June 2013 were reviewed.The 24 hours esophageal multichannel intraluminal impedance monitoring was performed in 8 cases of aerophagia.The treatment of these patients normally included psychological counseling,dietary adjustment,Iactulose,Domperidone and vitamins,while Simethicone was given to the patients if normal treatment was invalid.Results Of the 30 patients,aged 2 to 13 years,averaged (8.6 ± 4.5) years,the chief complaints were abdominal distention in 30 cases (100.00％),visible or audible air swallowing in 28 cases (93.33％),repetitive belching in 27 cases (90.00％),reduced appetite in 25 cases (83.33％),constipation in 22 cases (73.33％),psychological stresses in 15 cases (50.00％),recurrent abdominal pain syndrome in 10 cases(33.33％),chronic diarrhea in 3 cases(10.00％) and acute abdominal pain in 3 cases(10.00％).Among the 30 patients,24 hours esophageal multichannel intraluminal impedance monitoring was performed in 8 cases,averaging 149.63 (47-553)times of air swallowing were recorded.In the 30 patients,24 cases (80.00％) were relieved after being treated with psychological counseling,dietary adjustment,lactulose,domperidone and vitamins,and only 6 cases(20.00％) were invalid for normal treatment but well responeded to Simethicone.Conclusions Aerophagia is a kind of functional gastrointestinal disorders in children.Abdominal distention,air swallowing,repetitive belching,reduced appetite,constipation and pain are common symptoms.It can be cured through psychological counseling management,diet modification,laxatives,propulsives and vitamins.24 hours esophageal multichannel intraluminal impedance monitoring is a useful technology in the diagnosis of aerophagia children.

Objective To investigate the related factors of the prognosis of arterial embolectomy of acute cardiogenic cerebral embolism caused by atrial fibrillation.Methods The clinical data of using vein thrombolysis bridging artery embolectomy or arterial embolectomy alone for the treatment of patients with acute cardiogenic cerebral embolism of cerebral large artery occlusion due to atrial fibrillation were analyzed retrospectively.From January 2015 to December 2016,22 consecutive inpatients with cardioembolic cerebral embolism caused by paroxysmal or persistent atrial fibrillation were enrolled,including 10 patients with the 90-day modified Rankin Scale (mRS) score 0-2 (good recovery group) and 12 patients with mRS scores 3-6 (poor recovery group).The clinical features,imaging data,and treatment of the patients in both groups were compared.The factors such as age,gender,preoperative international standardization ratio (INR),embolism position,whether bridging vein thrombolysis before thrombectomy,National Institutes of Health Stroke Scale (NIHSS) score at the onset,time of onset to reperfusion (TOR),whether using tirofiban,times of thrombectomy,modified Thrombolysis In Cerebral Infarction (mTICI) blood flow grade,and postoperative intracranial symptomatic intracerebral hemorrhage were analyzed.Results There were no significant differences in age,gender,preoperative INR,embolism position,the number of intravenous thrombolysis before thrombectomy,the number of using tirofiban in surgery,the proportion of the above mTICI 2b grade,and the proportion of symptomatic cerebral hemorrhage after surgery of the patients between the two groups (P>0.05).The NIHSS score 15.2±2.0 at the onset in the good recovery group was lower than 22.9±8.4 in the poor recovery group.There was significant difference between the two groups (P<0.05).The TOR time (307±86 min) in the good recovery group was less than that of the poor recovery group (426±145 min).There was significant difference between the two groups (P<0.05).Embolectomy was performed 1.5 (0.5,3.0) times in the good recovery group,which was less than the poor recovery group (4.0 [2.0,7.0] times).There was significant difference between the two groups (P<0.05).Conclusions Shortening the time of reperfusion and reducing the number of embolectomy during operation are the important factors for improving the prognosis of patients when atrial fibrillation causes arterial embolectomy in patients with acute cerebral embolism.However,a study of larger sample is needed for further exploration.

Objective To study the changes of the putamen metabolites with magnetic resonance spectrum(MRS),and to explore possible underlying unrecongnised aetiological factor and pathophysiology mechanism in the central nervous system of the patients with Tourette' s syndrome.Methods Twenty-two cases of Tourette' s syndrome,and twenty-two gender and age-matched subjects ( the control subjects ) were performed on a clinical 3.0 T MRI system.Proton prob-voxel spectroscopy imaging (1H-MRS) was obtained from two sides of the putamen.The metabolites included N-acetylaspartate (NAA),creatine and phosphocreatine ( Cr),choline-containing compounds (Cho),and myoinositol ( MI ).The value of the NAA,Cr,Cho,and MI were calculated by integration of their peaks.The ratios of NAA/Cr,Cho/Cr,ML/Cr were calculated respectively.Repeated measures analysis of variance ( ANOVA ) was used to test both the value of NAA/Cr,Cho/Cr,MI/Cr of the putamen for group difference,with group as between-subjects factor and side as within-subjects factor.Results The NAA/Cr ratio in patients ( left:1.29 ± 0.13 ; right:1.34 + 0.15 ) was significantly lower than that in the control subjects ( left:1.50 ± 0.08,T =1.962,P ＜0.05 ; right:1.52 ± 0.11,T =1.865,P ＜ 0.05 ).There was no significant difference in the Cho/Cr and MI/Cr ratio between both groups.Conclusion The abnormalities of the structure and(or) function in the putamens of patients may be the one of the underlying anaetiological factors and pathophysiology mechanisms of the Tourette' s syndrome.

ObjectiveTo investigate the central nervous system mechanisms of active of movement switch in the patients with Tourette' s syndrome( TS),and to explore the possible underlying distinct neural networks for tic trigger and generation. Methods Participants were 14 patients with TS and 14 age- and gender-matched healthy volunteers with no history of physical,psychiatric or neurological disease: All patients were assessed with functional magnetic resonances imaging (fMRI)of the brain during the intermittent performance of finger-tapping switch tasks,Blood-oxygen-level dependent-fMRI was performed using a 3.0 Tesla MR.The area over which the activation was distributed was calculated,and the activation volumes were also compared between the patients with TS and the control subjects.ResultsThe regions activated in the patients with TS and in the volunteers were similar in several brain regions,including contralateral precentral and postcentral gyrus,contralateral mesia pre-front gyrus,contralateral cingulate gyrus,contralateral insula and ipsilataral cerebellum. There were also many different activation areas between the patients and the control subjects. The patients with TS demonstrated more significant and extended activation in the contralateral pre- and postcentral gyrus than the healthy volunteers.The volume of the left pre- and postcentral gyrus of the TS patients was (8.024 ±0.071 ) cm3,while the volume of the left pre-and postcentral gyrus of the control subjects was ( 6.480 ± 0.026) cm3 ( t =3.026,P ＜ 0.01 ) ; The volume of the right pre- and postcentral gyrus was (6.192 ± 0.019) cm3 in the TS cases,while there was (5.608 ±0.037) cm3 in the control subjects (t =2.752,P ＜0.05).There were significant differences in the volumes of bilateral pre- and postcetral gyrus between the TS and control subjects. The activations of conralateral thalamus without contralateral insula were found in the patients with TS. Conversely, the contralateral insula activation without thalamus activation could be found in the healthy volunteers.ConclusionThe thalamus might play an important role in the aetiological and physiopathologic mechanisms of the TS. The thalamus along with the parietal cortex,cingulate cortex and insular cortex appear to constitute a distinct neural network for tic trigger and generation.

Objective:To analyze the clinical and endoscopic findings of non-variceal upper gastrointestinal bleeding (NVUGIB) in children and to evaluate the efficacy of endoscopic treatment.Methods:A total of 56 children with NVUGIB admitted to Children′s Hospital Affiliated to Nanjing Medical University from May 2013 to April 2018 were enrolled.After admission, they were treated with endoscopic hemostasis, and they were divided into hematemesis group(8 cases), melena group(31 cases), and hematemesis + melena group(17 cases). In every group, hemoglobin level, blood transfusion rate, helicobacter pylori infection rate, source of hemorrhage, microscopic grading, hemostasis and results were statistically analyzed which they were compared with domestic and foreign studies.Results:In terms of hemoglobin level, hematemesis group was (92.00±25.66) g/L, melena group was (70.29±19.08) g/L, hematemesis + melena group (65.12±12.62) g/L.The differences among the 3 groups were statistically significant ( F=363.301, P<0.01). For blood transfusion rate, 25.00%(2/8 cases) was in hematemesis group, 74.19%(23/31 cases) was in melena group, and 94.12%(16/17 cases) was in hematemesis + melena group.There were significant differences among the 3 groups ( χ2=13.286, P=0.002). Totally, 50 cases (89.28%) were infected with Helicobacter pylori, and there were no significant differences among the 3 groups ( χ2=2.315, P=0.314). About bleeding source, 45 cases (80.35%) suffered from duodenal bulbar ulcer, 8 cases(14.28%) experienced gastric ulcer, 3/56 cases (5.35%) had gastric duodenal compound ulcer, and there were 25 cases(44.64%) with severe digestive tract bleeding.Forrest grade Ⅰa 2/56 cases [3.57%, 2/2 cases of rebleeding (100%)], Ⅰb 10/56 cases [17.85%, 2/10 cases of rebleeding (20%)], Ⅱa 3/56 cases (5.35%), Ⅱb 4/56 cases (7.14%), Ⅱc 2/56 cases (3.57%), and Ⅲ 35/56 cases (62.5%). Forty-eight cases (85.71%) accepted injection hemostasis, 2 cases (3.57%) obtained titanium clip hemostasis, 2 cases (3.57%) had injection + titanium clip hemostasis, 2 cases (3.57%) performed injection + titanium clip + electricity hemostasis, and 2 cases (3.57%) were given injection and surgical hemostasis.Totally, 52 cases (92.85%) achieved successful endoscopic hemostasis, 2 cases (3.57%) had successful second hemostasis, and 2 cases performed surgical operation (3.57%). Conclusions:In children with NVUGIB who need endoscopic hemostasis, duodenal ulcer is the main resource, Helicobacter pylori is the main cause.Children with melena are more likely to have severe bleeding and higher transfusion rate.Endoscopy is the preferred method for diagnosis and treatment.For Forrest Ⅰa and Ⅰb, the conbination of hemostasis under endoscope is more effective.

OBJECTIVETo investigate the causes and strategy of difficult intraarterial mechanical thrombectomy (≥3 times) in patients with acute ischemic stroke (AIS).

METHODSThe clinical data of 8 cases of AIS with thrombectomy ≥3 times admitted in Department of Neurology, the 306(th) Hospital of People's Liberation Army from June to October in 2015 was analyzed retrospectively. There were 7 male and 1 female patients, aged from 38 to 86 years with an average age of (70±15) years, in which 5 cases were cardiogenic cerebral embolism and 3 cases were large artery atherosclerotic infarction. The National Institute of Health stroke scale (NIHSS) score (M (QR)) was 16 (12) before procedure and modified thrombolysis in cerebral infarction (mTICI)score were 0 in all the patients. Solitaire AB was used in thrombectomy in the occlusion of the arteries.

RESULTSThe causes of difficult intraarterial thrombectomy included multiple thrombus, tortuosity in vascular paths, guiding catheter being placed below the internal carotid artery siphon leading to weak strength of suction and support of stent, embolus dropping in the thrombectomy and inadequate anesthesia. After successful thrombectomy 3 cases had mTICI score of 2a, 4 cases of 2b, 1 case of 3. The NIHSS score was 5 (24) at 7(th) day after treatment. At the 90-day follow-up 5 patients had good prognosis (modified Rankin score 0 to 2) and 3 had disability (modified Rankin score 3 to 4).

CONCLUSIONCases of AIS with difficult intraarterial thrombectomy can be treated by improving thrombectomy materials and technique, reasonable anesthesia and perioperative medication in decision-making strategy.

Objective To evaluate the effect of compound glycyrrhizin on the prevention and cure of cytarabine syndromes. Methods A total of 130 patients with hematological malignancies treated by moderate or high dose of cytarabine in the 303th Hospital of PLA from July 2010 to July 2016 were included. Patients were randomly divided into the control group and the experiment group by using random number table method, and each group had 65 patients. In the control group, patients were treated with cytarabine alone. In the experiment group, patients were treated with cytarabine plus compound glycyrrhizin. Skin rash and fever in patients of the two groups were also recorded. Results of blood routine tests, liver and kidney function tests were monitored during the treatment. Results Sixty-one patients in the experiment group and 63 patients in the control group were enrolled finally. In experiment group and control group, the differences in the incidence of cytarabine syndromes [8.2 % (5/61) vs. 41.3 % (26/63), χ2＝ 18.1, P < 0.001], skin rash [1.6 % (1/61) vs. 12.7 % (8/63), χ2＝16.3, P <0.001], and fever [6.6 % (4/61) vs. 36.5 % (23/63), χ2＝5.63, P <0.017] were statistically significant. There was no significant difference of the incidence of liver injury and minimum blood cell count between the two groups (P＞ 0.05). Conclusion Compound glycyrrhizin can effectively reduce the incidence of cytarabine syndromes, but the larger size and multiple center studies are needed to further verify the effect.
