Objective To understand the current status of intestinal helminth infections in Dafeng City. Methods The resi?dents in 5 villages of Dafeng City were investigated and their stool samples were detected for the eggs of helminth with Kato?Katz technique and Enterobius vermicularis was detected by the cellophane anal swab method. Results The total infection rates of intestinal helminth were 5.77% 5.51% 4.60% 4.18% 3.41% and 1.38% from 2005 to 2010 respectively. The trend of total infection rates declined year by year. The infection rates in the 20?30 age?group and 60?80 age?group were higher than those in other age?groups. The infection rates of the male and female were 5.63 359/6 375 and 2.42 144/5 949 re?spectively and there was a significant difference χ2=74.81 P=0.00 . The infection rate 11.70% in the northern areas of Dafeng City was higher than that in other places and the trend of the infection rates decreased from the eastern and northern to the western and southern. The infection rate of E. vermicularis was 1.75%in children in 2010. Conclusions The infection rate of intestinal helminth is low but E. vermicularis infection is relatively general in the children in Dafeng City. Therefore the pre?vention and treatment still need to be strengthened.

Glucocorticoid(GC) /glucocorticoid receptor(GR) inhibits cell proliferation and protects cells from apoptosis induced by serum deprivation,hypoxia,irradiation or chemotherapy drugs in many cell types,thereby GC/GR can maintain cell number homeostasis,which is an important aspect of homeostasis regulation of GC/GR in higher organisms.This article reviews antiproliferative and antiapoptotic effects of GC/GR on cell and their molecular mechanism,mainly focusing on the molecular events and target genes downstream of GC/GR.

Objective To observe the expression of CD_(25),CD_(25) mRNA,interleukin-1?(IL-1?) in peripheral blood of newborns with hypoxic-ischemic encephalopathy(HIE) and its clinical significance.Methods The peripheral blood mononuclear cells(PBMC) of newborns with HIE and normal controls were isolated by routine Ficoll-Hypaque,and the level of CD_(25) induced and non-induced by phytohernagglutinin(PHA) were detected by biotin-streptavidin(BSA),CD_(25) mRNA was detected by real-time PCR and IL-1? in serum was detected by enzyme-linked immunosorbent assay on the first,third and seventh day after birth.The final expressive level of CD_(25) mRNA was based on rate of CD_(25) cDNA and gluceraldehyde phosphase dehydrogenase(GAPDH).Results On the first day,the positive rates of CD_(25) induced and non-induced by PHA and IL-1? were(3.6?1.1)%,(20.9?4.8)%,(17.7?8.2) ng/L,respectively.There were significant differences in HIE group and normal controls(P0.05).Conclusions There is obvious inflammatory(rea)ction in babies with HIE.The main character of PBMC of newborns is all infantile and undifferentiated,which surface sign is infantile,and lower level of CD_(25) is expressed.However,the level of CD_(25) mRNA can be expressed consistently during the course of disease.The immunity and immune regulative response in newborns is gradually built up during the growth and can participate in recondition of brain injury caused by HIE.

Brain injury is one of the most common diseases in PICU.Bedside electroencephalogram monitoring is the most commonly used to evaluate cerebral function.Bedside electroencephalogram monitoring includes continuous electroencephalogram,video electroencephalogram and cerebral function trends,such as amplitude integrated electroencephalogram,envelope and band power.

ObjectiveTo imitate the process of identifying episode separations,which helps to improve the methodology of control episode separations.Methods Abstracts of inpatient record on all patients discharged from the hospitals in Beijing in 2010 were drawn from Beijing Public Health Information Center.Risk-adjusted by Diagnosis Related Groups-Beijing version (BJ-DRGs),two-weeks readmission rate was calculated at the whole city and hospital levels respectively.Comparing the readmission rate between these two levels,“suspicious objects”of episode separations can be found.In turn,the episode separations can be identified by detail analysis of these suspicious objects.Results In 2010,there were 13 DRGs with readmission rate exceeding 10％.Take the cases of dementia and other chronic brain disorders for example,the readmission rate for this type of inpatients in hospital G was much higher than the average level of the whole city.After the detail analysis of hospital G,the episode separations were found.Conclusion It is an effective method to indentify episode separations that calculating readmission rate based on the DRG risk-adjustment and using city level readmission rate as bench-mark.

Nosocomial infection of Pseudomonas aeruginosa is a dilemma in clinic,especially at ICU with high rate of antibiotic resistance,and lead to ventilator associated pneumonia,bloodstream infections, etc.There are difficulties in the treatment,lengthening of ICU stay,high mortality and increased treatment costs.Positive prevention,early diagnosis,reasonable antiboitics are the key to the benign prognosis of Pseud-omonas aeruginosa.

OBJECTIVE:To study the anti-hepatofibrotic action of 18?-glycyrrhizic acid(18?-GL) and gamma interferon (IFN-?) in rats METHODS:The rat model of liver fibrosis was induced by dimethyl nitrosamine(DMN),18?-GL or IFN-? was administrated before and 5 weeks after giving DMN,to prevent and treat liver fibrosis The pathological changes and degree of fibrosis in the liver were observed and compared with that of DMN control group RESUTLS:Compared to DMN control group,the collagen deposition in both 18?-GL and INF-? groups was significantly slight in degree(P

AIM: To investigate the effects of synthetical glucocorticoid dexamethasone(Dex) on the activation of two members of mitogen-activated protein kinase (MAPK) family, extracellular signal-regulated protein kinase1/2(ERK1/2 ) and p38 MAPK (p38) in human ovarian cancer cell line HO-8910. METHODS: The activation of ERK1/2 and p38 was determined by Western blot. RESULTS: Inhibition of activation of ERK1 and ERK2 by 10 -7 mol/L Dex occurred at 5 min, with maximum up to 41% and 54% respectively at 30 min ( P

OBJECTIVE:To determine the content of hydroxyproline in liver tissue in rats with hepatic fibrosis.METHO_ DS:RP-HPLC was used with precolumn derivation by2,4-dinitrochlorobenzene(DNCB)in the Borax buffer solution for lh in boiling water.Acetonitrile-acetate buffer linear gradient elution was used.Detecting wavelength was360nm.RESULTS:Derivation of hydroxyproline could be separated from other amino acids and accurately determined.CONCLUSION:The method is rapid,accurate,and suitable for detection of biopsy samples obtained by liver puncture.
