Objective To analyze the effect of fiber bronchoscope bronchial lavage technique for the children with lobar pneumonia.Methods 110 cases of lobar pneumonia were divided into the bronchial lavage group (55 cases) and the control group (55 cases).The clinical effect of two groups was observed.Results The tempera-ture recovery time, chest rales recovery time, clinical presentation time, X -ray change recovery time of bronchial lavage groups were significantly shorter than those of the control group (all P<0.05).The total effective rate of the lavage group was 85.5%,which was 65.5% of the control group (χ2 =10.632,P <0.01).Conclusion The children with lobar pneumonia taken bronchoscopy and bronchoalveolar lavage reached the diagnosis and achieved the goal of treatment,it could significantly improve the clinical symptoms,promote disease recovery,conducive to rehabili-tation of children.

Thyroid-associated ophthalmopathy (TAO) is an inflammatory eye disease associated with thyroid autoimmune disorder.The traditional treatments have yielded limited efficacy but with some side effects.Recently,researches have shown that some new immunosupressants may be used for the treatment of TAO with significantly improved symptoms,and reduction in clinical activity score.

OBJECTIVE To study the dynamic changes and clinical significance of TNF-? and IL-10 of nosocomial infection in patients with severe viral hepatitis.METHODS The study included 40 patients with severe viral hepatitis,their nosocomial infection was treated with antibiotic therapy.Serum levels of TNF-? and IL-10 were measured at baseline and 5 d,10 d and 15 d after the first antimicrobial dose.The patients were divided into 2 groups: infection be controlled group and infection be not controlled group by therapeutic efficacy.RESULTS The serum concentrations of TNF? and IL-10 were elevated in all patients when compared with the healthy control group(P

Objective To design a stimulating instrument for physiology experiment.Methods A sine wave was produced by a high frequency oscillator,and then the sine wave increased in voltage by a transformer to accord with the maximal range needed.Afterwards,the increscent sine wave became a direct current signal with high voltage by a rectifier and a filter.Finally,the signal became a stimulating impulse to be exported by a switch,which was controlled by a controlling signal with adjustable frequency and width.Results Voltage range adjusted between 1 and 80V;Frequency adjusted between 0.1 and 200Hz;Impulse width adjusted between 0.1 and 5ms.Conclusion The stimulating instrument designed can be used to do electricity stimulating experiment in Physiology.

Minerals and trace elements are a general name for a variety of elements that constitute human tissues and maintain normal physiological functions. The single-nucleotide polymor-phism ( SNP) can affect the metabolism, disposition and effect of minerals and trace elements, causing changes in body function. In this review, we will summarize pharmacogenomics research based on the current knowledge from minerals and trace ele-ments.

Objective To investigate the clinical characteristics of 34 systemic onset juvenile idiopathic arthritis (SoJIA) complicated with macrophage activation syndrome (MAS) and analyzed the gene PRF1,UNC13D,STX11,STXBP2 to figure out the genetic pathogenesis mechanism.Methods The clinical characteristics of 34 SoJIA complicated with MAS were analyzed retrospectively and coding sequences of PRF1,UNC13D,STX11 were amplified and tested.The Chi-square test was applied to compare the distribution of alleles and genotypes frequencies between SLE patients and healthy controls.Statistical significance was defined as P value ＜0.05.Results A total number of 34 SoJIA complicated with MAS were included.Boys accounted for 69％(23/34),and the median age was 6 years.85％(29/34) cases had genetic tests and four SNPS loci were detected:PRF1 c.1061 C＞T (rs885822); UNC13D c.659 C＞T (rs3744007); STXBP2 c.1483 T＞cC (rs10001) and STXBP2 c.1616 A＞G (rs6791).Compared with the control group,genotype and allele frequency of PRF1 rs885822 and STXBP2 rs10001 in MAS cases were statistical significantly different (rs885822:allele frequency x2=4.52,P=0.03 ; genotype frequency:x2=5.52,P=0.02.rs10001:allele frequencyx2=21.33,P=0.00; genotype frequency:x2=19.58,P=0.00).There was no statistical significant difference in genotype frequency and allele frequency of UNC13D rs3744007 and STXBP2 rs6791 between the MAS and control group (rs3744007:allele frequencyx2=1.89,P=0.17; genotype frequency:x2=1.59,P=0.45.rs6791:allele frequency x2=l.69,P=0.19; genotype frequency:x2=2.09,P=0.35).Persistent fever,progressive hepatos-plenomegaly,a sharp decline in blood cells counts,pleural effusion,markedly increased serum liver enzymes,hyperlipidemia were the main characteristics.Some children had mucosal bleeding,neurological dysfunction.More than 82％ children had upper respiratory tract infection before the occurrence of MAS.90％ of children were in remission,while three children had multiple organ failure and died.Conclusion MAS is a fatal complication caused by immune disturbance.Early detection and tre-atment is the key to improve the prognosis.The SNP PRF1 rs885822 and STXBP2 rs1001 may be concurrent with the pathogenesis of SoJIA-MAS.The SNP UNC13D rs3744007 and STXBP2 rs6791 may not participate in the pathogenesis of SoJIA-MAS.

Objective To explore the effects of Ganoderma spore(germination activated Ganoderma spore) on survival and expression of neurotrophin_3(NT_3) and nitric oxide synthase(NOS) of injured motor neurons in rat spinal cord. Methods Different dosages of Gandoerma spore were irrigated into the rat's stomach respectively in experimental groups after oneside ventral root cut.The survival ratio of injured motor neurons was counted.NT_3 expression of surviving motor neurons was measured by immunohistochemistry and in situ hybridization methods and NOS activity was measured by enzymo_histochemistry method. Results Thirty_five days after ventral root cut,the survival ratio of motor neurons was 47.32% in control group,and those were 67.11%,72.67% and 81.67% respectively in low,medial and high dosage Ganoderma spore groups.Expressions of NT_3 and NOS of surviving motor neurons in high dosage Ganoderma spore group were higher than those in control group.Conclusion Ganoderma spore may promote the survival of injured spinal motor neurons,and survival ratio of injured motor neurons is related to the dosages of Ganoderma spore.Ganoderma spore may also enhance the expressions of NT_3 and NOS of surviving spinal motor neurons.

Objective To investigate whether the skin-derived neural stem cells inducted by the culture could survive,differentiate and migrate in the lesioned site of rat spinal cord.Methods The skin of new born rat trans-gene of green fluorescence protein(GFP) was applied to be dissociated into cells,cultured and inducted to proliferate in vitro.Skin-derived neural stem cells were identified by immunocytochemistry staining.Then,skin-derived neural stem cells inducted by the culture were transplanted into the lesioned site of rat spinal cord hemisection.Thirty days and sixty days after the operation,the survival,migration and differentiation of transplanted cells were observed by immunocytochemistry staining. Results Ten days at cultured skin-dissociated cells,many cell-spheres had been formed by the proliferation of suspensive growing cells.These cell-spheres showed nestin positive staining of immunocytochemistry.It suggestes that the cell-spheres are neurospheres.In vivo,many transplanted skin-derived neural stem cells with GFP were observed in the lesioned area of spinal cord.Some transplanted cells migrated into host spinal cord tissue far away from the lesioned area.Some transplanted surviving cells showed nestin,MAP2 and GFAP positive staining of immunocytochemistry separately.Conclusion Skin-derived neural stem cells inducted by the culture may survive,migrate and differentiate into neuron-like cells and astrocyte-like cells in injured spinal cord of rat.
