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 get a better understanding of the characteristic MRI appearances of cerebral MS lesions.Methods 61 patients with clinically diagnosed multiple sclerosis were examined with SE sequences,using 0.5T super-conducting scanner.The MRI features of MS were analyzed.Results All of the patients in 61 cases were found MS lesions in MRI.The lesions in cerebral,brainstem,and cerebellum were clearly visualized,but in optic nerves were not so good.The MS foci appeared low or middle signal intensity in T 1WI and high signal intensity in T 2WI.It was playing an important role in the diagnosis of the MS that the paraventricular lesions were perpendicular to the lateral ventricles and there were MRI abnormal signals in corpus callosum with shrinking. Conclusion MRI can show the characteristic appearances of MS lesions,demonstrate many more lesions that not visible on CT scan,provide informations about the number,size,location and extent of the lesions therefore MRI is the first method of choice in the diagnosis of MS.

Purpose:To investigate whether transforming growth factor ?1 (TGF ?1) pathway is involved in the mechanism of dexamethasone (Dex) mediated proliferation inhibition in ovarian cancer cell line HO 8910.Methods:To analyse cell proliferation and cell cycle distribution by cell counts and flow cytometric analysis, respectively ; to determine the expression levels of TGF ?1 and its two receptors, T?R Ⅰ and T?R Ⅱ , by quantative RT PCR, ELISA and(or) immunocytochemistry methods.Results:Dex induced a G 0 /G 1 cell cycle arrest in HO 8910 cells, and it up regulated T?R Ⅱ expression in a concentration dependent manner.The level of T?R Ⅱ mRNA was the highest after treatment with Dex for 8 hours, with 1.4 fold more than that of control at concentration of 10 -7 mol/L ( P

Posterior scleritis,an inflammatory disease of the posterior sclera,is most commonly seen in middle-aged women and often associated with systemic immunological diseases.It presents with a variety of nonspecific signs and symptoms,and its clinical feature may be confused with ocular tumors,orbital inflammation,and retinochoroidopathy.Therefore,some auxiliary examinations are necessary for the diagnosis of posterior scleritis.With early proper diagnosis and treatment,severe complications of posterior scleritis can be avoided or lessened.In the paper,some advancement in the study of etiology,incidence,signs,symptoms,auxiliary examination,differential diagnosis and treatment of posterior scleritis were reviewed.

Primary intrahepatic stone is a common disease in China. It is difficult to treat this benign biliary tract disease because it has many complications and the surgery is difficult. Understanding the cause of this disease has important implications in prevention and treatment. This article reviewed the cause of primary intrahepatic stone from four aspects: imbalance of bile components, infection, bile protein, and macromolecular and metabolism of the cells.

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.

Objective Vessel overload index (VOI)was studied to monitor patients with hypertensive cerebral hemorrhage.Methods 144 cases with hypertensive cerebral hemorrhage were divided into two groups at random.One group was treated with mannitol plus urapidil hydrochlorid and the other with mannitol alone as controls.VOI were observed before and 2～4 hours after treatment and the changes of VOI values were analyzed with t-test.Results There was no significant difference in VOI values between groups before treatment (P＞0.05),but after treatmen (P＜0.05),30 day mortality was 18.18% in controls and 8.7% in observed groups.Conclusion VOI can be used to evaluate vessel load in hypertensive patients with cerebral hemorrhage and to indicate hypotensive therapy properly.

Multiple myeloma is a malignancy of plasma cells,which is still incurable now.Despite dramatic improvement of the response rate and overall survival have been made due to the application of target therapy and stem cell transplantation,the treatment effect is difficult to maintain,nearly all patients will eventually relapse and become refractory.At relapse,the challenge is to select the appropriate treatment for each patient.The decision will be both disease-dependent and patient-dependent.
