AlM:To investigate the features on prolonged central serous chorioretinopathy ( CSCR ) by optical coherent tomography ( OCT ) and to provide the basis of deciding the pathogenetic condition and prognosis. METHODS: Eighty - five patients who had been diagnosed with CSCR were grouped by suffering time as below: 32 patients suffered longer than 6mo as the prolonged and 53 patients with CSCR cured within that time. The imaging features of OCT were compared between the above groups.RESULTS:The incidence rate of neuroepithelial serous detachment extent above 500μm associated with pigmentary epithelial detachment in suffering eye and pigmentary epithelial damage in contralateral eye was significantly different between two groups. However, the incidence rate of neuroepithelial serous detachment extent above 4 000μm was not significant difference.CONCLUSlON:OCT could display clearly the change of every layer of retina with simplicity and visibility, which supplies us a new horizon to diagnose and trace CSCR. We could decide the pathogenetic condition and prognosis in accordance with the features of OCT, to provide references for the diagnosis and treatment of CSCR.

Objective To assess the value of combination of susceptibility weighted imaging (SWI)and dynamic susceptibility-weighted contrast-enhanced (DSC) perfusion-weighted magnetic resonance imaging in astrocytoma grading.Methods SWI and DSC scans were performed in 82 patients with pathologically confirmed astrocytoma.The patient group consisted of grade Ⅱ (15),grade Ⅲ (10),and grade Ⅳ (57).The intratumoral susceptibility signal intensity (ITSS) and relative cerebral blood volume (rCBV) max were used to determine the grade of astrocytomas by Kruskal Wallis test,Welch test,Spearman correlation coefficients,Pearson correlation coefficients,and receiver operating characteristic curve (ROC)statistic methods.Results There were no ITSS in 14 cases of low-grade astrocytomas,the degree of ITSS were grade 1 to 3 in anaplastic astrocytomas,the degree of ITSS were grade 3 in all of the glioblastomas,the degree of ITSS were significant difference in all grades (H =71.96,P ＜ 0.01).rCBV max in grade Ⅱ,grade Ⅲ and grade Ⅳ astrocytomas were 1.26 ± 0.42,3.59 ± 2.09 and 8.34 ± 1.16 respectively,rCBV max were significant difference in all grades (F' =681.72,P ＜ 0.01).ITSS showed significant correlation with rCBV max (r =0.72,P ＜0.01) and tumor grades (r =0.89,P ＜0.01),and rCBV and tumor grades showed significant correlation (r =0.78,P ＜ 0.01).Area under the ROC curve application SWI,DSC,SWI and DSC in differentiation of the grade Ⅱ and grade Ⅲ astrocytomas were 0.99,0.93,1.00,differentiate grade Ⅲ from grade Ⅳ were 0.70,0.94,0.94,and differentiate high-grade from low-grade astrocytomas were 1.00,0.99,1.00.Conclusions ITSS is helpful to determine the grade of astrocytomas.The use of SWI in combination with DSC may improve the diagnostic accuracy of astrocytoma grading.

Objective To investigate treatment of caesarean scar pregnancy (CSP) and associated problem.Methods From January 2011 to January 2013,57 cases with CSP undergoing treatment in Affiliated Hospital of Hebei University were studied retrospectively.Among 57 patients,it was divided into 12 cases treated by curettage (curettage group) ;22 cases treated by uterine artery embolization(embolization group) ;8 cases treated by laparotomy(laparotomy group) and 15 cases treated by transvaginal debridement (transvaginal group).Results (1) Successful rate of curettage group,embolization group,laparotomy group and transvaginal group were 12/12,86％ (19/22),7/8,13/15.(2) The intraoperative blood loss and the hospital stay were 20 (17-28) ml,(5.1 ± 1.9) days in curettage group,10 (5-15) ml,(10.2 ± 3.2) days in embolization group,200 (80-300) ml,(11.3 ± 3.3) days in laparotomy group,50 (45-100) ml,(6.8 ± 1.2) days in transvaginal group.There was statistically different between curettage group and embolization group (P ＜ 0.05).There was statistically different between laparotomy group and transvaginal group (P ＜ 0.05).Conclusions Curettage,uterine artery embolization,abdominal and transvaginal scar debridement surgery can be used in treatment of the CSP.It should be carefully chosen with surgical intervention,if myometrium was implanted greater than 1/2,or near to serosa.It should be carefully chosen with vaginal surgery,if the blood flow signals was rich around the lesion.

Objective To prepare monoclonal antibody(McAb) against human tissue kallikrein (HK) and develop an ELISA kit allows for the in vitro quantitative determination of human tissue kallikrein in urine. Methods To generate a monoclonal antibody specific for TK, the synthetic TK peptide consisting of 12 amine acids(12P), was fused to keyhole limpet hemocyanin(KLH) and used for immunization. Using hybridoma screening, monoclonal secreting cell lines were identified and used to generate ascites in BALB/c mouse. Antibody was purified by affinity column chromatography. 12% SDS-PAGE and Western blot were used to visualize the purified antibody. This kit employs indirect competitive ELISA technique and BiotinAvidin System. 12P was fused to bovine serum albumin(BSA) and has been pre-coated onto a microplate at first. Standards and samples were added to the appropriate microplate wells with a biotin-conjugated McAb croplate well. A TMB substrate solution is added to each well. The enzyme-substrate reaction is terminating by the addition of a sulphuric acid solution and the color change is measured spectrotometrically at a wavelength of 450 nm. The concentration of tissue kallikrein in the samples is then determined by comparing the O.D. of the samples to the standard curve. Results 8 hybridoma cell lines secreting mAbs special to HK,SDS-PAGE and Western blot demonstrated successful preparing and purification of McAb( 100% ). The linearity of this ELISA kit is demonstrated(r =0. 990). The range of detection of the assay is 0.008 μg/ml to 0. 5 μg/ml. The assay remained stable, with no change in the values measured, over five cycles of freezing and thawing. Conclusion 8 McAbs against HK have been prepared successfully and possess high titer and specificity. The development of an ELISA kit for detecting HK can meet the needs of detection of HK in urine samples.
