Objective To observe the regulating effect of inhaling glucocorticoid on imbalance of IL-4/interferon-?(IFN-?) cytokines in children with first onset wheezing .Methods IL-4 and IFN-? levels were examined in separated serum of 60 children wheezing with first onset wheezing,they were divided into abnormal level of IL-4/IFN-? group (n=38) and normal level of IL-4/IFN-? group(n=22,group C) depending on the level of IL-4/IFN-?,and 38 cases with abnormal level of IL-4/IFN-? were randomly divided into group A and B.Group B and C were given routine treatment without intervening treatment,while group A inhaled beclomethasone dipropionate aerosols for 3 months after routine treatment.Twenty healthy children for routine physical examinations in the same period were selected as healthy control group,who were examined for IL-4 and IFN-? with the same methods.Results Before treatment,the levels of IL-4 and IL-4/IFN-? in group A and B were significantly higher than those in group C and healthy control group(Pa

Objective To learn about electrolytes imbalance and water intoxication in children treated with high-dose cyclophosphamide(HD-CTX)as well as the renal function and the relative clinical symptoms,and study the mechanisms of hyponatremia.Methods Patients' clinical manifestations during and after HD-CTX therapy were summarized.Serum electrolytes and creatinine(Cr)were detected before and 6 or 8 hours after therapy with HD-CTX,antidiuretic hormone(ADH) in some patients were measured.Results Of 108 therapeutic cases 24 accompanied with vomits and 22 with a decreased urine output,in which 4 developed eyelid or ankle edema.Seven cases had neural-sarcous symptoms and 5 cases had abdominal pain or diarrhea.Serum sodium decreased significantly after HD-CTX[(139.12?3.30) mmol/L vs(134.06?8.23) mmol/L] in whom rechecked after 6 h,(141.77?3.59) mmol/L vs(133.26?6.41) mmol/L in those rechecked after 8 h(Pa0.05].Serum Cr increased 8 h after therapy[(29.95?13.61) ?mol/L vs(43.33 ? 17.25) ?mol/L P

Objective To evaluate the role of TCD examination in diagnosis of the early cerebrovascular diseases in aged diabetic patients.Methods 179 cases of aged type Ⅱ diabetic patients were divided into three groups(PDR,BDR and NDB)according to their retinopathy.TCD and retina examination were performed in all patients and the data be analysed. Results (1)The systolic peak flow velocity(Vp) of MCA、ACA、ICA and BA were significant increased in diabetic pa- tients than in normal control group(P

Bacterial resistance has always been a challenge in the field of antibacterials research. As one of the most problematic pathogens causing nosocomial infections, Acinetobacter baumannii (A. baumannii) was a severe threaten to public health. In recent years, as the rate of multidrug-resistant, extensively drug-resistant, and even pan drug-resistant A. baumannii has been increasing, there is an urgent need to develop new strategies to combat this pathogen. Iron is an essential element for the survival and the infection process of A. baumannii. Bacteria have developed a series of iron uptake strategies to survive in conditions of the host iron starvation, including the secretion of siderophore for iron chelation, the uptake of ferroheme, and the transport of ferrous by Feo system. Developing antibacterial strategies to inhibit the iron uptake is an effective way to deal with A. baumannii infection. This article will review the mechanisms of iron uptake by A. baumannii and the antimicrobial strategies developed based on them.

Objective To study hemodynamics of cerebral blood flow in newborns with asphyxia.Method Bilateral cerebral electrical admittance plethysmogram(BCEAP) was used to explore characteristics of cerebral blood flow in 20 healthy newborns and 20 newborns with asphyxia respectively from first to fourth day after birth.Results Both the ratio of Hs to b-S(Hs/ b-S) and index of admittance differential loop(ADL) Ⅰ+Ⅱ decreased significantly in newborns with asphyxia compared to normal control from first to fourth day after birth(P

Calcium hydroxide (CH) is applied to improve disinfection of root canals in most root canal retreatment. This study aimed to analyze the CH removal efficacy using 7 different root preparing files (K file, pre-curved K file, EndoActivator, Ultrasonic file, pre-curved ultrasonic file, F file and needle irrigation alone) with apical transportation. Standardized models of curved canal with such apical transportation or not were set up before applying CH to root canal for 7 days. Seven techniques described above were used for its removal. Then the roots were disassembled and digital photos were taken. The ratio of residual CH in the overall canal surface was calculated using the image analyzer image pro plus 6.0. The data were analyzed using one-way ANOVA with post hoc Tukey test. Results revealed that CH was effectively removed (P<0.05) by using all 6 mechanical methods except irrigation alone. In curved root canals with apical transportation, EndoActivator, pre-curved ultrasonic file and F file were found to be more effective in removing CH than the other four file (P<0.001), while there was no significant difference among EndoActivator, pre-curved ultrasonic file and F file groups (P>0.05). The percentage of residual CH in the canal with apical transportation was higher than that in the canal without apical transportation (P<0.05). In conclusion, CH can be hardly removed completely. Canal with apical transportation will result in insufficient CH removal. EndoActivator, pre-curved ultrasonic file and F file are more effective in the curved root canal with apical transportation.
