Objective To explore the relationship of etiopathogenesis,therapy and prognosis in children with chronic arrhythmia.Met-hods Forty cases aged 48 h to 12 years old between Sep.2003 to Oct.2006 were selected.All children had vertigo,syncope,Adam-Stoke syndrome,cardiac shock.Some cases were detected with complete atrioventricular block(CAVB)(33 cases),sinus bradycardia(5 cases) or sick sinus syndrome(2 cases) by electrocardiogram(ECG) at least 2 times,and these symptoms lasted 3 days at least.Congenital CAVB children having no clinical symptom were given no treatment.Cases having sinus bradycardia,sick sinus syndrome resulted from viral myocarditis,the earlier were given antiviral medicine,energy composition,intravenous megavitamin C,isoprenaline,and large dose of adrenocortcal hormone simultaneously.Some were given human ?-globulin.Eight of them were set temporary pacemaker because of unsatisfactory treatment,and 2 of them were set permanent pacemaker.Results Twenty-eight cases were cured,9 cases were improved and 3 cases died.Six out of the cured cases and improved cased were set permanent or temporary pacemaker.Conclusions Early discovery,early diagnosis,and early temporary pacemaker use will lead a better prognosis in regular treatment.On the contrary,the delayed treatment on children with viral myocarditis and CAVB caused by dilated cardiomyopathy will lead a negative prognosis.

Objective To explore the clinical significance of detection of IL-17 and peripheral blood eosinophil(EOS) count in whee-zing children under 5 years old.Methods Fifty-three children with recurrent wheezing under 5 years old had been randomly enrolled including 43 boys and 10 girls.They were divided into 2 groups :wheezing group Ⅰ,in which,the patients with atopic high risks(n=27);whee-zing group Ⅱ,in which,the patients without atopic high risks(n=26).Children without infectious diseases such as hernia and renal calculus had been enrolled randomly as control group(n=20),including 11 boys and 9 girls.After taking 3 mL venous blood and centrifuging of patients in 3 groups,the level of IL-17 in the serum was measured by double-antibody sandwich enzyme-linked immunosorbent assay,peripheral blood EOS count was performed in the meantime by means of eosine staining.Results The serum levels of IL-17 in wheezing groups [(1 469.315?978.300) ng?L-1,(263.340?131.800) ng?L-1]were significantly higher than that of control group[(36.478?2.000) ng?L-1](Pa0.05);serum IL-17 and peripheral blood EOS count had positive correlation(r=0.933,P

AIM: To investigate the clinical value of fundus fluorescein angiography ( FFA ) and optical coherent tomography ( OCT) in the diagnosis of central retinal vein occlusion.
●METHODS:A total of 47 cases (47 eyes) central retinal vein occlusion were retrospectively analyzed from Jun. 2012 to Dec. 2015 in our hospital ophthalmology center. According to the final diagnosis, the results were divided into 21 cases of central retinal artery occlusion ( group CRAO, 21 eyes) and central retinal vein occlusion ( group CRVO, 26 eyes ) . All patients received FFA and OCT examination within 2wk of onset, and the image data of the two kinds of examination results were analyzed.
● RESULTS: Group of patients with CRAO average macular foveola thickness, angle measuring, filling time determination results were significantly lower than that of the patients with CRVO group average and the differences were significant (P<0. 05).
●CONCLUSION:FFA and OCT images of central retinal artery and vein occlusion have their own characteristics, and the combination of these two images can be used to identify and diagnose the central retinal artery and vein occlusion.

Objective To explore the effect of status epilepticus(SE) on learning and memory and expression of phosphorylated c-AMP response element binding protein(pCREB) in hippocampus in developmental rats.Methods Developmental male SD rats were assigned randomly to two groups:the SE rats,induced by intraperitoneal injection of pentylenetetrazole(PTZ);normal saline(NS) control group,received saline intraperitoneal.Learning and memory test with the Morris water maze and Y maze were performed at 7 days after SE.After testing,a subset of rats were killed and the brain was evaluated for pCREB immunostaining,an important transcription factor underlying learning and memory.Results In SE group,the mean escape latency of searching the platform significantly prolonged(P

Objective To study the different expressions of receptor activator of nuclear factor-kappa B ligang(RANKL) mRNA in spleens of rats fed with diet of low calcium and high fluoride. Methods A 2× 2×2 factorial design was used and the factors were calcium, fluoride and action time. In the design, 40 Wistar rats [average body mass(118.9±13.5)g] were divided into four groups randomly by weight: control with normal diet (0.790%, calcium), low calcium group with low calcium intake(0.063%, calcium), high fluoride group with normal diet and high fluoride intake(100 mg/L, fluoride) and low calcium and high fluoride group with low calcium and high fluoride intake. After 4 and 8 months, 5 rats of each group were sacrificed and total RNA was extracted from spleen. And the expression levels of RANKL mRNA were determined by reverse transcription polymerase chain reaction (RT-PCR). Results At time of 4 months, the expression level of RANKL mRNA was 0.13± 0.05,0.13± 0.03,0.17±0.02,0.27± 0.05 and at time of 8 months, it was 0.11 ± 0.01,0.16 ± 0.02,0.16± 0.03,0.36 ± 0.07 in control group, low calcium group, high fluoride group, low calcium with high fluoride group, repectively. The factorial design AVONA showed that low calcium and high fluoride had significant effects on RANKL mRNA expression(F = 40.224,56.679, all P < 0.05) while action time had not(F = 2.850, P > 0.05 ). The interactions of low calcium with high fluoride or high fluoride with action time were signifieant(F = 7.247, 18.789, all P < 0.05) while the interaction of high fluoride with action time was not(F = 1.751, P > 0.05). Conclusions Low calcium alone or high fluoride alone or low calcium with high fluoride or low calcium with action time can increase the the RANKL mRNA expression level. High fluoride does not affect the RANKL mRNA level as the action time is prolonged.

It has been showed that there were obvious obstacle effects of Panax notoginseng replanting. Crop rotation was the main effective technique to overcome the obstacle. To find a reasonable crop rotation system for P. notoginseng, aqueous extracts from root, stem and leaf of P. notoginseng were analyzed for allelopathic effect on three maize varieties (which are often grown in regions where P. notoginseng grown). The main results were as follows: (1) Allelopathic effect of P. notoginseng stem and leaf extracts on the three other tested plants was stronger than that of root extracts; (2) Corn was more vulnerable to the effects of allelochemicals at seedling stage than at germination stage, and the corn root was more sensitive than aerial part to allelochemicals; (3) Lusan No. 3 and Yunrui No. 1 showed resistance to P. notoginseng allelopathy, with respective comprehensive sensitivity indexes (M3) of - 0.089 3 and -0.159 2, while Bainuo No. 1 is sensitive at M3 = -0.261 0. It then can be concluded that Lusan No. 3 and Yunrui No. 1 may be an alternative rotation plants for overcoming P. notoginseng continuous cropping obstacle.
