Objective To analyze the clinical characteristics and prognosis of acute pyelonephritis (APN) in children.Methods A retrospective analysis was performed in 230 pediatric patients with APN admitted from January 2009 to December 2010.The clinical characteristics,etiology,drug-resistant and prognosis were reviewed,and logistic regression analysis was performed to identify the risk factors of renal scarring after APN.Results Among 230 patients with APN,93 were boys and 137 were girls with a malefemale ratio of 1∶ 1.47.Ninety-nine patients were younger than 1 year with a male-female ratio of 1.30∶1 ;75 patients were 1 to 5 year with a male-female ratioof 1 ∶ 2.75 ; 56 patients were older than 5 year with a male-female ratio of 1∶2.29.A total of 106 strains were detected,in which 91 strains were Gram-negative bacteria,13 strains were Gram-positive bacteria and 2 strains were fungus.The most frequent bacteria were Escherichia coli (65 strains,61.32％),Klebsiella pneumonia (13 strains,12.6％) and Enterococcus faecium (9 strains,8.49％).Forty-four strains of Escherichia coli produced ESBLs,and all of them were resistant to ampicillin,part of them resistant to cephalosporin,compound sulfamethoxazole and aztreonam,but all were sensitive to amikacin,amoxicillin/clavulanic acid,nitrofurantoin,and imipenem.Renal emission computed tomography (ECT) was performed again in 52 children who were followed up for 6-12 months,in which 31 cases (59.62％) developed renal scar,and 21 cases (40.38％) were recovered.Abnormalities in urinary system or vesicoureteric reflux were identified as the risk factors for renal scarring after APN (OR =6.89,P ＜ 0.05).Conclusions The incidence of APN in children drops with age,which is frequently in the males younger than 1 year,and in the females older than 1 year.Escherichia coli is the most frequent pathogen of APN in children,and most strains are multidrug resistant.Children with abnormalities in urinary system or vesicoureteric reflux are prone to develop renal scarring.

A real-time monitoring reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the sensitive and specific detection of prototypic,prevalent North American porcine reproductive and respiratory syndrome virus (PRRSV)strains.As a higher sensitivity and specificity method than reverse transcription polymerase chain reaction (RT-PCR),the RT-LAMP method only used a turbidimeter,exhibited a detection limit corresponding to a 10-4 dilution of template RNA extracted from 250 μL of 105 of the 50% tissue culture infective dose (TCID50) of PRRSV containing cells,and no cross-reactivity was observed with other related viruses including porcine circovirus type 2,swine influenza virus,porcine rotavirus and classical swine fever virus.From forty-two field samples,33 samples in the RT-LAMP assay was detected positive,whereas three of which were not detected by RT-PCR.Furthermore,in 33 strains of PRRSV,an identical detection rate was observed with the RT-LAMP assay to what were isolated using porcine alveolar macrophages.These findings demonstrated that the RT-LAMP assay has potential clinical applications for the detection of highly pathogenic PRRSV isolates,especially in developing countries.

During the course of meibomian gland dysfunction (MGD) treatment, meibomian gland massage is an effective auxiliary method. Based on an extrusion method using anti-phase massage rollers and a theory on envelope plane, a massage mechanism was proposed in this paper for the defect of the traditional mechanical assist massage structure to discharge obstruction of Meibomian gland more smoothly and to enlarge massage coverage. Meanwhile, for the case that the power of motor was significantly limited by size, an evaluation, about the input, output and loss, was carried out to initially verify the feasibility of the designed mechanism.

Objective To study the effects of thymus transplantation(TT)combined with CD4--DLI on T cell reconstitution after allogeneic hematopoietic stem cell transplantation(allo-HSCT). Methods BALB/c mice were randomly divided into three groups:hematopoietic stem cell transplantation (HSCT group),hematopoietic stem cell transplantation combined with thymus transplantation(TT group)and hematopoietic stem cell transplanta-tion combined with thymus transplantation plus CD4+ T cell-depleted lymphocyte infusion(CD4--DLI group). On day-1,the mice were treated with the lethal dose of radiotherapy. On day 0,C57BL/6 mice were used as donor for hematopoietic stem cell transplantation. The mice were sacrificed on 5 days,2 weeks,4 weeks and 3 months after transplantation,respectively. The peripheral blood and spleen cells of mice were collected for determinations of T cell surface antigen,T cell receptor,naive T cells and intracellular cytokines. HE staining was used to assess the development of donor thymus. Results TT and CD4--DLI did not impair each other′s effects on T cell reconstitu-tion. TT combined with CD4--DLI increased the number of T cell reconstruction. CD4--DLI promoted the effect of TT on enlargement naive CD4+and CD8+T cell pool. Combination of TT and CD4--DLI enhanced the cytokine pro-duction of T cells. Conclusion TT combined with CD4--DLI had no side effects on TCR repertoire and thymus. Conclusion TT combined with CD4--DLI can enhance the reconstitution of T cell number and function via thymus dependent and thymus independent mechanism.

Objective:To investigate the diagnosis and treatment significance of invasive and noninvasive operation for ventilator?as?sociated pneumonia ( VAP ) . Methods:A total of 80 cases of VAP suspected patients who had received mechanical ventilation at least 48 hours in ICU from Jun 2014 to Mar 2015 were enrolled. Patients were randomly divided into four groups including noninvasive operation group ( F) , invasive operation group ( Q) , mix group 1 ( H1) and mix group 2 ( H2) . VAP diagnosis rate between groups as well as living time, antibiotic use time, survival rate, calcitonin levels and APACHE II score, oxygenation index were analyzed. Results:Specimen from invasive operation had higher specimens to cultivate positive rate than that from noninvasive operation ( P<0?05), but there was no statistic significant difference in VAP diagnosis rate between two methods (P>0?05). Conclusion:Noninva?sive operation collecting samples for VAP diagnosis is also accurate as invasive one. Collecting specimens from sputum suction tube in the clinical treatment on airway suction is a low cost and simple noninvasive operation.
