Severe mycoplasma pneumoniae pneumonia is indicated as severe clinical symptoms,long course of disease,many extrapulmonary complications and the response to conventional therapy is poor.Its incidence has been increasing day by day,the inefficiency of host resistance to m ycoplasma pneumoniae,disorders of immune response and pathogenic immune escape are suggested to play critical roles in the immune mechanism of severe mycoplasma pneumoniae pneumonia.This paper summarizes the progress of immunopathogenesis of severe pneumoiae pneumonia in children.

This paper analyses and discusses the procedures and results of a project on the college English teaching mode ( 3+1+S+A ) in Chongqing Medical University. It has been found from the experimental results that this teaching mode, which is characterized as three-term condensed required courses, one-term optional courses, self-access language learning and extra-curriculum activities, contributes significantly to the improved English proficiency and performance of non-English majors.

Objective To analyze the situation of the intellectual development of children between 0 to 18months.Methods Using Denver Developmental Screening Test(DDST),1 064 children aged between 0 to 18 months in four items:their indicidual and social reaction ability,subject-touching reaction ability of fingers,and speaking ability as well as movement ability were tested,each itern had 2 kinds of tests and here only need to test one kind which is shown on the left part of DDST.Every example need to understand the pregnancy history,family history,birth of children,past history,parents'jobs and education level.The measured results were calculmed,about the ages of which 50%examlnation could pass in each test itern and 90%could pass,and compared with tested children in Denver.Results The passing rate of same item would be increased as age increases.the passing rate would be different between different test items in the sslne age,and the more difficult the item,the lower the passing rate.The common trend of children's intellectual development Was in accordance with that of Denver children,whereas there were age differences that pass certain items.Conclusion As a screening way of infants'intellectual tests,DDST had universal significance.Lacking scientific education was an important cause of mental retardation in children.

Objective To explore the relationship of DNA damage and cell apoptosis in the blood vessel endothelial cell of diabetic rats. Methods Streptozotocin was used to make diabetic rats, 16 rats were random divided into diabetic group and control group. DNA damage was measured by comet assay and cell apoptosis was detected by flow eytometry. Results DNA damage score was 29.5 ± 6.7 and 8.6±3.6 in diabetic rats and controls, the rate of cell apoptosis was respectively 10.9±3.5 and 4.4 ± 1.2. It had a significant difference between two groups in DNA damage and cell apoptosis(P < 0.05). The rat of cell apoptosis had strongly positive correlation with DNA dam-age scores (r = 0.82, P < 0.05). Conclusion DNA damage and cell apoptosis are found in diabetes mellitus, cell apoptosis may be asso-ciated with DNA damage. The roles of DNA damage and cell apoptosis in diabetes mellitus need further research.

Invasive fungal infection(IFI) is becoming increasingly important issue in pediatrics and pediatric intensive care unit. IFI often occurs in newborns and children with immune dysfunction. Candida and Aspergillus spp. are the most commonly isolated organisms. Early diagnosis can improve the prognosis of IFI. The 1,3-β-D-glucan(G)test,galatomannan antigen(GM)test and PCR test can aid earlier dignosis for IFI in high-risk children.

The epidermal growth factor receptor ( EGFR)-small molecule tyrosine kinase inhibitor (TKI) has become the focus of clinical trials for first-line treatment of advanced non-small cell lung cancer ( NSCLC). Though TKI and concurrent chemotherapy show no advantage for survival, the use of TKI in combination with chemotherapy ( sequenced or maintenance) prolongs progression-free survival. In those patients with EGFR mutation, TKI as monotherapy in first-line setting has a significant effect on progression - free survival compared with chemotherapy. These data shows that EGFR mutation is effective predictor for TKI treatment.

CD163 is one of transmembrane glycoproteins expressed only in activated monocyte-macrophage cell membrane, which acts as a marker of activated macrophages. In sepsis, CD163 activates the intracellular signal transduction pathways in macrophages,regulates TNF-α, IL-10 and IL-6 expression, have antiinflammatory and antioxidant effects in the inflammatory process. Soluble CD163 (sCD163) is a soluble form of CD163 ,which could play anti-inflammatory and immunoregulatory effects by inhibiting T cells proliferation and activation. Serum concentration of sCD163 may be highly increased when severe infection. Detection of serum sCD163 is helpful to diagnose sepsis,and to evaluate the prognosis of severe infection and sepsis.

Objective: To explore the relationship between coxsackie-adenovirus receptor(CAR)expression and the infection efficiency of adenovirus vector in gene therapy for hepatocellular carcinoma through regulating CAR expression on cells surface via inhibition of the Raf/MEK/ERK pathway.Methods: Western blotting analysis was used to examine CAR expression in hepatocellular carcinoma cells(SMMC-7721 and HepG_2)before and after treatment with U0126,inhibitor of Raf/MEK/ERK signal transduetion.SMMC-7721 and HepG_2 were infected by a non-replicating,E1 A-deleted adenovirus expressing EGFP(Ad-GFP).FACS was used to analyze the infection efficiency of Ad before and after U0126 treatment. Results: The expression of CAR on cell surface had an increasing tendency after treatment with U0126.FACS analysis showed significantly increased infectivity of cells treated with the MEK inhibitor U0126 compared with untreated cells: SMMC-7721,(71.65?6.21)%→(86.54?5.70)%,HepG_2,(77.53?4.62)%→(87.06?2.83)%,when infected with Ad-GFP at the same MOI(10 MOI).Conclusion: The inhibition of Raf/MEK/ERK pathway by U0126 may up-regulate the expression of CAR in some hepatocellular carcinoma cells,which subsequently enhances the susceptibility of adenovirus infection to target cells.
