Objective To explore influential factors and features of relapse of presenting with an initial episode of acute central nervous system inflammatory demyelinating disease(IDDCNS) in children.Methods By group-control study,20 relapsing patients with IDDCNS compared with 50 single episoding patients with IDDCNS whose case history longer than 0.5 year,whose age at onset,gender,preceding infection or immunization,neurologic syndromes at presentation,therapeutic response,and final neurologic outcome after initial episode were analyzed by mono-factor analysis and multi-factor nonconditional Logistic regression model.Results 1.The risk of relapse increased in the near future,75.0% relapsed before 6 months.There were 18 cases diagnosed multiple sclerosis(MS),1 case neurooptic myelitis and 1 case immaturity myelitis in relapsing patients.There were 39 cases diagnosed acute disseminated encephalomyelitis in single episoding patients.2.Mono-factor analysis:8 factors were not statistically significant,including age at onset,gender,seizure,palsy,conscious disturbance,ataxia,natural relief,sequelae after the first attack;6 factors were statistically significant,including infectious or vaccination agents before episode,fever,visual disorder,multiple neurological signs,positive pathologic reflex,with marked improvement to cortical hormone.3.In the multi-factor stepwise regression analysis,visual disorder(OR=42.50)and positive pathologic reflex(OR=8.666)were the independent influencing factors,multiple neurological signs(OR=0.068)was independent protecting factor.Conclusions The rate of relapse in IDDCNS is lower than abroad and most relapse before 0.5 year,the main diagnosis of relapsing case is MS.When visual disorder and positive pathologic reflex presenting in the fist episode of IDDCNS,the opportunity of relapse will increase,and will decrease when multiple neurological signs presenting.

Objective:To study the change of immunological response and cell proliferation in breast tissues augmented by polyacrylamide hydrogel injection(PHI).Methods:The expression of CD68,CD25 and PCNA in 20 breast tissues with indurations,12 without indurations after breast augmentation by PHI,and 10 normal breast tissues was examined by immunohistochemistry P-V6000; analysis was also done by H-E staining.Results:Hyperplasia of fibrous tissue and infiltration of inflammatory cells and macrophages were found in the breast and adjacent tissues 3-8 years after PHI.Positive cells of CD68,CD25 and PCNA hardly existed in the normal tissues,but the breast tissues around the polyacrylamide hydrogel had many positive cells of CD68 and PCNA,especially in cases with indurations;there were significant differences between the 3 groups(P

Objective:To compare psychosocial factors and immune function between patients with breast cancer and benign tumor before operation.Methods:The patients of breast tumor(56 case)were measured by clinical psychological rating scale(EPQ、HAMD、HAMA、LES、SSRS、DSQ)before operation,and their serum levels of IgA, CD_4~+,CD_(19)~+ and the activity of NK cell were measured.The patients of breast tumor were divided into breast cancer group(36 case)and benign tumor group(22 case)bases on results of pathology.Results:In breast cancer group, there were significantly higher scores of neurotic,total and negative life events,immature defense styles,HAMA and HAMD than those in benign tumor group;while NK cell activity,levels of CD_4~+ and CD_(19)~+ and the score of mature defense,social supports,subjective supports and utility degree of supports were marked lower.There were significantly correlation between immune function(NK cell activity,content of CD_4~+,CD_(19)~+,IgA)and psychosocial factors(social support,P score of EPQ,HAMD and HAMA total score,quantity of negative life events etc). Conclusion:Cancer patients had more server psychosocial problems and lower immune function.The immune function of patient with breast cancer before operation is associated with the various psychosocial factors.

Objective To study the value of magnetic resonance imaging(MRI) in the diagnosis and treatment of pelvic neoplasms. Methods The patients who were suspected of malignant pelvic neoplasms were performed MRI.The surgical approach was determined according to the MRI results.The MRI results were compared with operation findings and pathological reports. Results The MRI results were consistent with operation findings and pathological reports in 22 cases highly suspected of pelvic neoplasms and 15 cases with abnormal endometrial echo.Therapeutic regimen was designed for 5 cases with uterine cervix cancer according to MRI stages,and favourable surgical curative effects were obtained. Conclusion MRI provides a reliable guideline for surgical approach and may improve the outcomes.

Objective To investigate the diagnostic value of thinprep cytologic test(TCT) and electronic colposcope(EC) examination in patients with subclinical human papillomavirus(HPV) infection(SPI) and cervical intraepithelial neoplasia(CIN),and explore its concordance with pathologic diagnosis. Methods A total of 1 125 females were examined with TCT,744 of whom diagnosed with abnormality by TCT or suspect of cervical lesions were examined with EC,and multiple punch biopsies were performed in 706 of those with abnomal EC images and suspected diseases. ResultsThe sensitivity of TCT,EC examination and the combined examination of TCT and EC for SPI and CIN were 88.74%,88.79% and 90.63%,respectively,the specificity 85.44%,80.38% and 96.41%,respectively,the positive predictive value 74.06%,68.90% and 91.10%,respectively,and the negative predictive value 94.19%,93.61% and 96.21%,respectively.By the combination of the two examinations,the specificity and positive predictive value were significantly increased(P

Background Retinopathy of prematurity (ROP) is one of major causes of childhood blindness.Early screening and treatment of ROP is necessary.Objective This study was to analyze the incidence of ROP in single and multiple premature infants and related factors.Methods This study was approved by Ethic Committee of Suzhou Municipal Hospital,and oral informed consent was obtained from the parents of the infants before any medical examinations.Five hundred and four fetus with the gestational age of ≤34 weeks or birth weight of ≤ 2 000 g were collected in Suzhou Municipal Hospital,of whom 357 infants were single fetus birth and 147 infants were multiple fetus,including 26 twins and 21 three fetus birth.The fundus were examined by RetCam Ⅱ equipment and ROP was determined based on the fundus findings and history of birth.ROP incidences between the single fetus and multiple fetus were compared,and the inducing factors were analyzed.Results Sixty-six infants were ROP in all 504 fetus,with the incidence of 13.10％.The incidence of ROP in the single fetal group was 10.92％ (39/357),which was significantly higher than 18.37％ (27/147) in the multifetal group (x2=5.069,P=0.024),and risk of ROP in the multifetal group was higher than that in the single fetal group (OR =1.835).The oxygen inhalation rate was 42.02％ (150/357) and the oxygen inhalation duration was 5.71 days in the single fetal group,and that in the multifetal group was 58.50％ (86/147) and 9.42 days,respectively.Conclusions Incidence and risk of ROP in the multifetal infants are higher than those in the single fetal infants,and low-birth-weight,less gestational weeks and excess oxygen inhalation are influence factors.

Objective To explore the mobile changes of nitric oxide(NO) and the relationship between nitric oxide and glomerular hyperfiltration in experimental diabetic rats.Methods Experimental diabetes mellitus(DM) was induced in rats with streptozotocin(STZ).The levels of NO and NOS in renal tissue homogenate were assayed after establishment of diabetesat the 4 th,8 th,12 th week.At the same time, renal morphology in diabetic rats was examined by light microscope and image of computer.Results The contents of NO and NOS in renal homegenates were evidently increased at 4 th week,and decreased gradually from 8 th week(P
