ABSTRACT
Objective:To analyze risk factors for duration of small or medium-sized coronary artery aneurysms (CAA) in children with Kawasaki disease (KD) so as to provide clinical guidance for early and full course treatment.Methods:The clinical data of 68 children diagnosed with KD in the Department of Pediatrics, the First Affiliated Hospital of Xinxiang Medical University from January 2018 to January 2021 were retrospectively analyzed.According to duration of CAA, all cases were divided into 2 groups, duration of CAA ≥ 8 weeks group and duration of CAA <8 weeks group.Risk factors associated with CAA duration were screened using univariate analysis, and then independent risk factors for CAA duration in children with KD were analysed using multiple Logistic regression analysis. Results:A total of 68 cases were enrolled in this study.Among these cases, 45 cases (66.18%) were male and 23 cases (33.82%) were female.The onset age was from 3 months to 10 years old, and the median onset age was 1.59 (1.02-3.19). There were 31 cases in the group with CAA duration ≥8 weeks and 37 cases in the group with CAA duration <8 weeks.Univariate analysis showed that patients with the total fever course >10 days[45.16%(14/31 cases) vs.21.62%(8/37 cases)], time of treatment with intravenous immunoglobulin (IVIG)>10 days[54.84%(17/31 cases) vs.16.22%(6/37 cases)], platelet (PLT)>600×10 9/L[32.26%(10/31 cases) vs.10.81%(4/37 cases)], hypersensitive C-reactive protein (HsCRP) >100 mg/L[38.71%(12/31 cases) vs.13.51%(5/37 cases)] (all P<0.05 ) in the group with CAA duration ≥8 weeks were significantly more than those in the group with CAA duration <8 weeks.However, there were no significant differences in gender, age, type of KD, etiology evidence, hormone application, duration of fever before IVIG application, IVIG sensitivity, IVIG application way, urine leukocytes, white blood cells, hemoglobin, percent of neutrophilic granulocyte, erythrocyte sedimentation rate, glutamic-pyruvic transaminase between the 2 groups (all P>0.05). Multivariate Logistic regression analysis showed that the course of IVIG before application >10 days ( OR=6.589, 95% CI: 1.678-25.867, P=0.007)and HsCRP >100 mg/L ( OR=7.949, 95% CI: 1.947-32.461, P=0.004)were independent risk factors for predicting the duration of KD complicated with small and medium-sized CAA ≥8 weeks. Conclusions:The course of IVIG before application >10 days and HsCRP>100 mg/L are independent risk factors for KD complicated with small and medium-sized CAA lasting ≥8 weeks.
ABSTRACT
OBJECTIVES@#To analyze the differentially expressed genes (DEGs) with radiation-induced rat lung injury, and to reveal the protective mechanism for mild hypothermia in the radiation-induced lung injury in rats at the transcriptome level.@*METHODS@#A total of 10 male SD rats aged 6-8 weeks were randomly divided into 2 groups to establish a rat model of radiation-induced lung injury, and one group was treated with mild hypothermia. RNA was extracted from left lung tissue of each group, and sequenced by BGISEQ-500 platform. Significance analysis of DEGs was carried out by edgeR software. Gene ontology (GO) function enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were used to analyze the gene function. Then 5 key DEGs were verified by real-time reverse transcription PCR (real-time RT-PCR).@*RESULTS@#There were 2 790 DEGs (false discovery rate<0.001, |log@*CONCLUSIONS@#The DEGs and pathways related to mild hypothermia protection against radiation-induced lung injury in rats are obtained, which provides an experimental basis for the protection of mild hypothermia against radiation-induced lung injury.

Syncope is a common emergency condition,which can cause harmful danger to the physical and mental health,quality of living and learning of children.Even,syncope -related body traumatic injuries and anxiety and depression often occur in these children,and some have a high risk of sudden death.So,early diagnosis is of great sig-nificance.Head -up tilt table test is considered the gold standard for the diagnosis of syncope,it plays a significant role in diagnosis,differential diagnosis,treatment and evaluation of therapeutic effects.
ABSTRACT
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.
ABSTRACT
[Summary] Glucose-dependent insulinotropic polypeptide ( GIP) is known to promote the release of insulin fromβcells, but this function suffers from a defect in obese patients. More and more evidences suggest that GIP is the bridge between a high-fat diet, obesity, insulin resistance, and type 2 diabetes. With the deepening of research in GIP in type 2 diabetes and obesity, GIP may provide new ideas for the treatment of type 2 diabetes and obesity.
ABSTRACT
ObjectiveTo investigate the risk factors for syncope in children with orthostatic intolerance (OI).Methods The clinical data from 136 children with OI were retrospectively analyzed. The children were divided into syncope group and non-syncope group based on the existence of syncope. Results Among the 136 children, 77 children (56.62%) had syncope and 59 children (43.38%) did not have syncope. The differences in BMI, prevalence of inducement of prolonged standing, prevalence of accompanied symptoms of blurred vision/ blacking out, cold sweating and pallor, prevalence of the history of motion sickness and blood flow velocity of MCA were statistically significant between two groups (P<0.05). Conclusions Children with OI who has low BMI, inducement of prolonged standing, accompanied symptoms of blurred vision/ blacking out, cold sweating and pallor, the history of motion sickness, and fast blood flow velocity of MCA, are prone to syncope.
