0.05).No partial side-effect of the medicine were discorvered in the observation process.Conclusion Long-term inspiration of low-dose GCS to treating the babies and infants with asthma has reliable security.

Objective To investigate the impact of mind wandering in sustained attention response task, and offer interventions to cope with mind wandering. Methods In December, 2016, a total of 37 athletes were tested with sustained attention response task. Their technical index, reaction time variation and accurate rate were calculated. Results The statistics of 25 athletes showed that, the technical index was lower in complex task than in simple task (t(35)=-8.019, P<0.001). No significant difference was found in the reaction time variation between two tasks (t(23)=-1.575, P=0.129), the main effect of mind wandering was not significant (F(1,23)=0.488, P=0.492), as well as the interaction of mind wandering and task difficulty (F(1,23)=0.054, P=0.262). No significant difference was found in the accurate rate between two tasks (t(23)=-1.046, P=0.307), the main effect of mind wandering was not significant (F(1,23)=0.119, P=0.733), and the interaction of mind wander-ing and task difficulty was marginal significance (F(1,23)=3.608, P=0.070). Conclusion Athlete's mind wandering with awareness would influ-ence the performance in complex sustained attention response task. Mindfulness training and tasks engagement could effectively cope with mind wandering.

ObjectiveTo study the effect of hyperbaric oxygen therapy on the cholinergic neurons of hippocampus and praxiology of vascular dementia rats.MethodsThe vascular dementia models were made and divided into control and therapy group. After 30 days of HBO therapy, abilities of learning and memory of rats were tested by using the Morris water maze. Immunochemistry staining was used to observe the number of cholinergic neurons of CA1 subfield of hippocampus. ResultsAbilities of learning and memory of rats and the number of the neurons positive to ChAT like immunoreaction in the CA1 subfield of the hippocampus significantly increased in therapy group.ConclusionHyperbaric oxygen therapy is effective on the vascular dementia model rats.

Objective The purpose of this study was to evaluate the value of contrast-enhanced ultrasound in diagnosis of renal cell carcinoma subtyping.Methods 206 cases with renal tumors were confirmed by pathology and surgery from June 2012 to June 2014,including 113 male cases and 93 female cases.The mean age was 54 years (range 23-80 years).The subtype of renal tumor included clear cell carcinoma in 147 cases,papillary cell carcinoma in 32 cases,chromophobe cell carcinoma in 27 cases.All patients were received the CEUS before operation.The enhancement patterns,degree of enhancement,the appearance of necrosis and the time-intensity curve by contrast-enhanced ultrasound were analyzed.Results Enhancement patterns of CEUS were showed by fast in and fast out in 63.9％ (94/147)cases with clear cell carcinoma,59.4％ (19/32) cases with papillary cell carcinoma,51.9％ (14/27) cases with chromophobe cell carcinoma.Statistical significant diference was shown among those subtype groups (P ＜ 0.05).Most of the clear cell carcinomas (127/147,86.4％) showed hyperenhancing.While,the papillary renal cell carcinoma (22/32,68.8％) and chromophobe cell carcinoma (15/27,55.6％) showed hypoenhancing (P ＜ 0.05).The rate of necrosis in clear renal cell carcinoma was 62.6％ (92/147),and 59.4％ (19/32) in papillary cell carcinoma.necrosis area accounted for only 18.5％ (5/27)in chromophobe cell carcinoma (P ＜ 0.05).In the time-intensity curve analysis,the initial time,the average arrival time,the time to peak and area under the curve in renal cortex was (11.06 ± 2.75) s,(23.42 ± 2.79) s,(27.47 ± 3.02) dB,(35.01 ± 2.94)dB,respectively.Significant differences in those items were found in clear cell carcinoma,which was(8.01 ± 1.89) s,(20.05 ± 3.01) s,(30.03 ± 2.98) dB,(37.64 ± 4.01) dB respectively,compared with those in cortex (P ＜ 0.05).The arrival time,time to peak,peak intensity and area under the curve in papillary cell carcinoma were (1 1.12 ± 2.43) s,(27.29 ± 3.54) s,(20.13 ± 2.67) dB,(34.67 ±3.24) dB,respectively.The curve showed the time to peak was higher and the peak intensity were lower than those of renal cortex (P ＜0.05).The arrival time,time to peak,peak intensity and area under the curve in chromophobe cell carcinoma were (11.32 ± 2.90) s,(22.21 ± 3.62) s,(22.02 ± 2.52) dB,(28.67 ± 3.65) dB,respectively.The curve demonstrated peak intensity and area under the curve were lower than those of surrounding renal cortex (P ＜ 0.05).The increase of tumor diameter after contrast-enhanced ultrasound in clear cell carcinoma was about (0.35 ± 0.11)cm and in nonclear cell carcinoma was about (0.23 ± 0.10) cm (P ＜ 0.05).Conclusion The contrast-enhanced ultrasound played an important role in diagnosis and subtype renal cell carcinoma.

Objective To investigate the role of T follicular helper ( Tfh) cells in the immuno-pathogenesis of persistent immune thrombocytopenic purpura ( pITP) .Methods Twenty children with pITP and twenty healthy controls were enrolled in this study .The proportion of CD4+CXCR5+ICOShigh PD-1high T ( cTfh) cells and the expression of ICOSL on CD 19+B cells in peripheral blood of the patients and healthy subjects were analyzed by flow cytometry .The expressions of Bcl-6, c-Maf, IL-21 and ICOSL at mRNA level were detected by real-time PCR.The plasma concentrations of IL-2, IL-6 and IL-21 were determined by ELISA.Results (1) Compared with the healthy controls , the proportions of cTfh cells increased signifi-cantly in patients with pITP [(17.45±9.04) %vs.(7.57±2.57) %, P<0.05], but decreased with the treatment of dexamethasone (DEX) for 7 days [(5.93±1.64) %vs.(17.45±9.04) %, P<0.05].(2) The expression of Bcl-6, c-Maf and IL-21 at mRNA level in patients with pITP were higher than those in healthy controls (P<0.05).(3) Compared with healthy controls, the expression of ICOSL at mRNA and protein levels in CD19+B cells were significantly up-regulated in patients with pITP (P<0.05), which showed no significant changes after treatment with DEX (P>0.05).(4) The plasma concentration of IL-21 was remarkably elevated in patients with pITP , regardless of DEX treatment (P<0.05).But the plasma concentrations of IL-2 and IL-6 showed no significant changes compared with control group (P>0.05).Con-clusion The immunopathogenesis of persistent immune thrombocytopenic purpura might be associated with the hyper-activation of Tfh cells caused by excessive expression of ICOSL and IL-21.The persistent high expression of ICOSL and IL-21 might be one of the important factors resulting in the recurrence of pITP in children .

Objective To study the clinical and pathologic features of chromphobe renal cell carcinoma (ChRCC) and to evaluate the conventional pathologic prognostic parameters in prognosis.Methods Seventy-five cases (42 males and 33 females) with pathological confirmed ChRCC (36 on the left and 39 on the right kidney) after nephrectomy during 1998 to 2009 were retrospectively analyzed. Patient's age ranged from 25 to 74 years, with a mean age of 56 years. Evaluation of conventional prognostic parameters was carried out. Kaplan-Meier survival curve was used to study the survival relationship. Results The mean tumor diameter was 7.3 cm. The majority of tumor macroscopic surface color was gray and yellow or gray and red. The majority of tumor cells were big polygon chromphobe cell or small round eosinophils. The TNM stages of these ChRCC were as follows: 30 cases in T1N0M0, 1 in T1N0M1, 26 in T2N0M0, 1 in T2N0M1, 11 in T3N0M0, 3 in T3N0M1, 1 in T3 N1 M0, 1 in T4 N0 M1 and 1 in T4 N1 M1. The pathologic grade of ChRCC was G1 in 3 cases, G2 in 24cases, G3 in 46 cases and G4 in 2 cases. All the 75 cases were followed up for 9 to 93 months (mean 44months), 7 patients died and others were alive without recurrence and metastasis. 3-year and 5-year survival rates were 93.3% and 90. 7%, respectively. The univariable analysis showed that tumor size (P=0. 028), TNM stage (P＜0. 001) were associated with tumor progression. The multivariable Cox regression model revealed that TNM stage was an independent predictor of aggressive ChRCC. Conclusions The ChRCC tumors are generally larger than other types of RCC and with a favorable prognosis. Fuhrman nuclear grade is not suitable for ChRCC. TNM stage is an independent predictor of aggressive ChRCC.
