Objective To study the proportion of cyclic vomiting syndrome(CVS) developing to migraine by the medium term prognosis,and explore the relationship between CVS and migraine.Methods Twenty-eight of 38 cases who had identified in our clinical records were traced ,each child was matched to a control,and they all conducted a telephone interview by a standardized question.Results Ninteen(46%) of the subject had continued CVS and(or) migraine,the prevalence of past or present migraine in subjects(46%)was significantly higher than that in control group(10.7%)(P=0.003).Conclusion The progonosis of CVS is closely related to migraine,many of the suffers of CVS tend to develop migraine.

Background and Purpose:dPET/CT is very expensive,so although the accuracy of hPET/CT is less than dPET/CT,it is better than CT,and is useful for guiding the tumor staging before operation.This paper is evaluate the role of ~(18)F-fluorodeoxyglucose(FDG) hPET/CT in primary carcinoma of gastric cardia detection.Methods:26 patients with histologically proven primary carcinoma of gastric cardia underwent whole body hPET/CT imaging.Visual and semiquantitative analysis and standardized uptake value(SUV) were used to analyze the images.The results of hPET/CT study were compared with those of CT.Results:1.The sensitivity of hPET/CT in primary carcinoma of gastric cardia detection was 92.3%(24/26);two cases of signet ring cell carcinoma gave false negative results,and the primary lesions were small(

Objective:To establish a lung cancer model of patient-derived tumor xenografts (PDTX) and to explore the relation-ship between primary cisplatin resistance and ERCC1 and IGFBP5 expression levels. Methods:Lung cancer tissues from 84 patients who underwent surgery were collected and implanted into nude mice. Patient characteristics for the first generation xenografts that were and were not engrafted were compared. Passage 3 xenografts were treated with cisplatin. The expression levels of ERCC1 and IGFBP5 in cisplatin-resistant and cisplatin-sensitive groups were detected using immunohistochemistry assay. Results:The model success rates were 32.14%(27/84) in first-generation xenografts, 88.89%(24/27) in second-generation xenografts, and 95.83%(23/24) in third-gener-ation xenografts. The tumorigenicity of first-generation xenografts was correlated with size, differentiation, clinical stage, and histologi-cal type. PDTX tumors maintain the histological type of parental tumors through serial passage in nude mice. ERCC1 expression level was significantly higher in the cisplatin-resistant group than in the cisplatin-sensitive group, whereas the IGFBP5 expression level was lower in the cisplatin-resistant group than in the cisplatin-sensitive group. Conclusion:Lung cancer PDTX models were successfully es-tablished, and histological characteristics of the primary cancers were retained. Therefore, the models may serve a function in preclini-cal research of lung tumor biology and for exploring the drug resistance mechanism of tumors. The cisplatin resistance of primary lung cancer may be correlated with the expression level of ERCC1 and IGFBP5 in lung carcinoma.

ObjectiveTo investigate the ultrasonographic indicators predicting the outcomes of selective fetal growth restriction (sFGR)fetusesin monochorionic twinsunder expectant management. MethodsMonochorionic twins with sFGR diagnosed in the First Affiliated Hospital of SUN Yat-sen University from Jan.2005 to May 2010 were included into this study.All patients underwent expectant treatment.Ultrasound appearances of monochorionic twins were documented in detail when sFGR was diagnosed.At the initial evaluation,presence or absence of the following abnormalities were documented, including abnormal Doppler flowin theumbilical artery,polyhydramnios in the larger twin,oligohydramnios,fetal weight discordance and velamentous cord insertion in sFGR fetuses; gestational age at diagnosis was recorded as well.The relationship between these ultrasound characteristics and mortality of sFGR fetus was analyzed with Logistic regression.ResultsOf 51 sFGR fetuses,11 (21.6％) suffered from fetal death,including four intrauterine demise and seven neonatal deaths both twins were dead in 3 cases. Logistic regression analysis demonstrated that oligohydramnios (OR=22.80,95％CI:3.58-145.31,P=0.001) and abnormality of diastolic flow in the umbilical artery (OR=6.51,95％CI:1.16-36.53,P=0.033) were independent risk factors of mortality of sFGR fetuses. Conclusions Both oligohydramnios and abnormal Doppler flow in the umbilical artery suggest poor prognosis of sFGR fetuses in monochorionic twins.
