International Journal of Pediatrics 2016;43(1):33-35,40
Asthma is the most common chronic inflammatory airway disease in childhood. Adhering to a daily anti-inflammatory treatment is the most important cornerstone of bronchial asthma control. However,with the large number of clinical studies conducted in recent years,learning inhaled corticosteroids as an anti-inflam-matory drug of choice,there is a mixed compliance rate of inhaled corticosteroids in children. Standard treatment and control of asthma has yet to be further improved. This review discusses the medication adherence to long-term inhaled corticosteroid as well as the relevant aspects of research progress.

OBJECTIVETo explore the possible relationship between recurrent aphthous ulcer (RAU) and single nucleotide polymorphism (SNP) of transforming growth factor-β1 (TGF-β1)-509T/C and interleukin-10 (IL-10)-1082A/G sites.
METHODSA total of 138 RAU patients were recruited for this study. The control group consisted of 124 subjects. TGF-β1-509T/C and IL-10-1082A/G sites were detected by restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) and sequence specific primer-polymerase chain reaction (SSP-PCR). Relative risk ratios were estimated by odds ratios (OR) and 95% confidence interval (95%CI).
RESULTSSignificant differences were found in the genotype frequencies or allele frequencies of TGF-β1-509T/C and IL-10-1082A/G sites between the RAU patients and controls (P < 0.05). CT genotype (OR = 1.231, 95% CI = 0.702-2.160), TT genotype (OR = 2.482, 95% CI = 1.250-4.927), and T allele (OR = 1.465, 95% CI = 1.036-2.074) at the TGF-β1-509 site exhibited high risks. AG genotype (OR = 1.391, 95% CI = 0.808-2.396), GG genotype (OR = 4.165, 95% CI = 1.944-8.924), and G allele (OR = 2.134, 95% CI = 1.474-3.089) at the IL-10-1082A/G site also showed high risks.
CONCLUSIONTGF-β1-509T/C and IL-10-1082A/G sites are associated with the risk of RAU. The TGF-β1 gene-509T allele and IL-10 gene-1082G allele may serve as genetic determinants for RAU.

Objective:To explore the possible relationship between recurrent aphthous ulcer( RAU) and the single nucleotide polymor-phism(SNP)of IFN-γ+874A/T site and IL-2-330T/G site. Methods:138 RAU patients and the 124 health control subjects were in-cluded. IFN-γand IL-2 serum concentration were detected by ELISA. IFN-γ+874A/T site and IL-2-330T/G site of the whole blood were detected by RFLP-PCR and SSP-PCR. Results:IFN-γand IL-2 levels in serum of the patients were significantly lower than those of the controls(P<0. 05). There was significant difference in the genotype frequencies and allele frequencies of IFN-γ+874A/T site between the 2 groups(P<0. 05). The AA genotype(OR=9. 964)and the A allele (OR=3. 801) at the IFN-γ+874A/T site was with high-risk of RAU. Carry A allele in patients with risk of RAU was to carry the T allele of 3. 801 times. There was no significant differ-ence in the genotype frequencies or allele frequencies of IL-2-330T/G site between the 2 groups(P>0. 05). Conclusion: IFN-γ+874A/T site was associated with the risk of RAU. But,IL-2-330T/G site was not.

Objective To compare the cognitive difference of subjects'responses to the same visual stimuli under two different priming conditions,and to discuss the influence of inversion effect and configural changes upon facial recognition.Methods Priming pattern was employed,and subjects were induced to recognize the same stimuli as schematic faces or three English letters under different priming conditions.The participants'accuracy and reaction times were compared in two priming conditions. Results Participants'accuracy of the comparison stimuli in facial priming condition decreased significantly by inversion effect((79.03±10.53)%vs(89.43±9.98)%,P<0.01);reaction times of priming stimuli and comparison stimuli were delayed by inversion effect significantly((3720.40±607.71)ms vs(2998.33±544.02)ms,(3521.80±1038.20)ms vs(2750.87±867.13)ms,P<0.01),and there was no influence of inversion effect upon the reaction times of English letter stimuli(P>0.05).Correlations of accuracy to reaction times reached no significant difference under two conditions.Conclusion Priming effect make sense in the cognition,and there was a priming stage before the facial configuration.Inversion effect shows up in the face priming condition,and vanish in the English letter priming condition,which demonstrate the importance of configuration and inversion effect in the facial cognition.What's more,such effect can't be explained by the changes of cognitive difficulty.

Objective To investigate whether antiseptic central venous catheters (CVC) modified with chlorhexidine acetate and silver sulfadiazine can be beneficial in reducing bacterial colonization and catheter-related infection. Methods Prospective controlled non-blinded randomized clinical trial was conducted. Seventy adult inpatients with CVC from intensive care unit of General Hospital of Chinese People's Armed Police Force during June 2007-June 2009 were enrolled. Their baseline characteristics, APACHE Ⅱ score and therapeutic interventions were comparable. Patients were randomly received either an antiseptic CVC ( antiseptic group, n = 28) or a standard two-lumen CVC ( control group, n = 42 ). Microbiological evaluation was done after CVC removal. A catheter bacterial colonization ( CBC) was considered if bacterial growth of > 15 CFU was found by semi-quantitative roll-plate technique from a proximal or distal catheter segment. A catheter-related infection ( CRI) was defined as a colonized catheter with local signs of inflammation. A catheter-related bloodstream infection ( CR-BSI) was defined as a colonized catheter with isolation of the same organism from the patient' s blood with accompanying clinical signs of infection. SPSS 11.5 software was used for statistical analysis. Kaplan Meier curve was used to evaluate the association between CVC retention time and bacterial colonization or infection, and Log-rank test was performed to compare between the groups. Results CVC was removed from 3.6% (1/28) patients of antiseptic group and 21.4% (9/42) patients of control group because of infection (x2 = 5. 143, P <0. 05). Colonization of CVC was observed in 7. 1% (2/28) patients from antiseptic group and 35. 7% ( 15/42) from control group (x2 =7.458, P<0.01). CBC or CRI was not observed in antiseptic group until day 19, while CRI occurred at day 6 in the control group. CVC colonization and infection were developed in 31.4% and 14. 3% patients of antiseptic group during day 14-day 28 respectively, while the rates in the control group were 90% and 70% ( u = 27.5 and 14.31, P < 0.01). Conclusions Antiseptic CVC modified with chlorhexidine acetate and silver sulfadiazine can significantly lower the risks of CBC and CRI. But more than 50% patients would develop infection when colonization occured, no matter patients receive standard or antiseptic CVC. After CVCs have been inserted for > 2 weeks, the colonization and infection will increase significantly in both standard or antiseptic CVC, so to shorten the insertion time is an effective measure to decrease the CVC-related infection.
