MicroRNAs (miRNAs) are a class of small non-coding RNAs which involve in the regulation after gene transplantation.Researches show that miRNA is closely related to the development and progression of non-small-cell lung cancer (NSCLC).They caused a significantly change in NSCLC cells through downregulate tumor suppressor gene,or act as oncogene or work on some targets which is important in cell signal pathway,in the end it lead to oncogenesis,cell proliferation,cell apoptosis and resistance to chemotherapy or radiotherapy.Therefore,miRNA will be hopefully used in the diagnose and therapy of cancer.

N". Except the average (Avg)-RNFLT had positive correlation with diopter in severe myopia group (r=0.372, P=0.047), no significant correlation was observed in other parameters among three groups. Conclusion RNFLT in myopia measured by OCT may have its own rule. Avg-RNFLT may have positive correlation with diopter in severe myopia group.

Objective To discuss the clinical distribution and antibiotic resistance of 1909 strains of Pseudomonas aeruginosa(PA)to 19 antibiotics.Methods To collect and isolate clinical specimens from Jan to Dec in 2007,and analysis the drug resistance of 1909 stains of PA.Results The top three departments of infection rnte are Senior Officials inpatient Ward(38.9%),Neurology Department(28.1%)and Pneumology Department(19.58%).The drug with the highest level of antibiotic resistance is Trimethoprin/Sulfa(96.3%),the second one is Tetracycline(95.3%),and drugs with low level antibiotic resistance are imipenem(39.8%),Ceftazidime(29%),Piperacillin/Tazobactam(28%),amikacin(14%),respectively.Conclusion PA is a main pathogenic bacteria for bedridden patients and critically ill patients in ICU.It's important to choose antibiotics reasonably,and it's necessary to acontrol the path of hospital-acquired infection.

Objective To explore the lesion mechanism and the apoptosis related protein changes of kidney in rat suffered from obstructive jaundice. Methods Choledocho-ligation methods was used to create rat obstructive jaundice model. Six rats in the normal control group and thirty rats of experiment group were observed at day 1, 3, 6,10 and 14 after rat model establishment. HE staining for kidney pathological changes, TUNEL staining for cell apoptosis, SABC for apoptotic related proteins of survivin and bax, xanthine oxidase method for SOD activity and thiobarbiturate method for MAD content were carried out. Results Renal tubular epithelial cell necrosis, cell shedding and aggregation were the main pathological changes in the experiment group. In the experiment group, the apoptosis ratio increased significantly, and reached the peak of (25.2?2.8)% on postoperative day 14. The relative gray value of survivin in the experiment group decreased significantly and of bax increased significantly. The plasma SOD activity in the normal group was (193.6?23.5) U/L, but it in the experiment group decreased significantly. The plasma MDA content and the endotoxin level in the experiment group increased significantly. Conclusion Cell apoptosis is one of the lesion mechanisms of kidney in rats suffered from obstructive jaundice. The down-regulation of survivin and the up-regulation of bax may be the biological factor in the occurrence of apoptosis. The increasing of free radical and endotoxin are important factors in the kidney lesion.
