Objective To compare levels of glycosylated hemoglobin detected by 3 kinds of analytic instruments .Methods 75 samples were measured by D-10 glycosylated hemoglobin automatic analyzer(ionexchange chromatography) ,HA-8160 glycosylated hemoglobin automatic analyzer(affinity chromatography) and 7170A automatic analyzer(immune turbidimetry) .Results were tested by the homogeneity of variance ,the one-way analysis of variance and correlation analysis .Results There was a positive correlation between D-10 glycosylated hemoglobin automatic analyzer and HA-8160 glycosylated hemoglobin automatic analyzer(r2 =0 .996) , the linear equation was Y=0 .953X+0 .519 .There was a positive correlation between D-10 glycosylated hemoglobin automatic ana-lyzer and 7170A automatic analyzer(r2 =0 .996) ,the linear equation was Y=0 .925X+0 .576 .There was a positive correlation be-tween HA-8160 glycosylated hemoglobin automatic analyzer and 7170A automatic analyzer(r2 =0 .998) ,the linear equation was Y=0 .969 X+0 .081 .Conclusion In the premise of quality control in laboratory ,three different instrument can use to detect the level of glycosylated hemoglobin .

Objective To analyze the clinical characters,treatment and prognosis of primary malignant tumor in vagina.Methods A retrospective analysis of 42 patients diagnosed with primary malignant tumor in vagina in Peking Union Medical College Hospital(PUMCH)between Jan 1984 and Aug 2006 was performed.Results Primary malignant tumor accounted for 0.98%(42/4286)in the total gynecological malignant tumors during that period in PUMCH.According to the International Federation of Gynecology and Obstetrics(FIGO)staging system,19 cases were at stage Ⅰ,12 cases at stage Ⅱ,5 cases at stageⅢ,and 6 cases at stage Ⅵ.Thairteen cases were squamous carcinoma,13 cases were malignant melanoma,8 cases were adenocarcinoma.3 case8 were yolk sac tumor and 5 cases were other types.The majority of patients were treated with surgery combined with radiotherapy and chemotherapy.Up to August 2007,19 cases survived.18 cases were dead and 5 casefl were lost.The longest follow up was 10 years,with the median time of 2 years.The overall 2-year SUrvival rate was 60.6%.For stage Ⅰ,stage Ⅱ, and stage Ⅲ-Ⅵ,the 2-year survival rates were 71.3%.58.3%and 29.6%respectively.The 2-year survival rate of patients with squamous carcinoma Was 46.8%,malignant melanoma 72.9%,adenocarcinoma 20.0%and patients with yolk sac tumor were all alive tumor-free after 6-10 years'follow up.Conclusions The prognosis of primary malignant tumor in vagina is affected by clinical stage and histological type.A8 to malignant melanoma,radical surgery combined with chemotherapy and immunotherapy produce good effects.Patients with yolk sac tumor can be cured only with chemotherapy.As to other types,more treatment experiences are needed.

Objective:To investigate the characteristics of pregnancy with pre-excitation syndrome and its influence on pregnancy outcomes.Methods:A retrospective analysis was made on the clinical data of 62 cases of pregnancy complicated with pre-excitation syndrome in Beijing Anzhen Hospital from Jan. 2008 to Dec. 2008. According to whether there was a supraventricular tachycardia (SVT) in pregnancy, they were divided into two groups. There were 16 pregnant women in the SVT seizure group during pregnancy, and 46 pregnant women in no SVT seizure group, with a multi-disciplinary comprehensive diagnosis and treatment model. SPSS software was used to analyze the data and compare the gestational age, age and weight of the newborn, and then compare the pregnancy outcomes.Results:(1) The total number of deliveries in Beijing Anzhen Hospital during the study period was 21 786, and the patients with pregnancy combined with pre-excitation syndrome account for 0.28% (62/21 786). (2) Totally 44 patients (71%, 44/62) were diagnosed with pre-excitation syndrome before pregnancy, and 18 patients (29%, 18/62) were diagnosed for the first-time during pregnancy. Among patients diagnosed with pre-excitation syndrome before pregnancy, 16 patients (36%, 16/44) had seizures before pregnancy, 28 patients (64%, 28/44) had asymptomatic before pregnancy, and 4 of asymptomatic patients had SVT during pregnancy. (3) Of the 16 pregnant women in the SVT seizure group during pregnancy, 2 patients (2/16) had SVT episodes in the first trimester, 5 patients (5/16) had SVT episodes in the second trimester, 9 patients (9/16) had SVT episodes in the third trimester. In the SVT seizure group, 8 patients (8/16) had SVT episodes before pregnancy, and 8 patients (8/16) had no SVT episodes before pregnancy. There were 46 patients in the SVT seizure-free group during pregnancy, including 9 patients with SVT attacks before pregnancy and 37 patients without SVT before pregnancy. (4) Compared with the pregnant women in the SVT seizure group, the age, weight gained during pregnancy, delivery gestation week, newborn weight, and the time of the first and second labors were not statistically different between the two groups of pregnant women (all P>0.05). However, the total duration of labor in the SVT seizure group during pregnancy was shorter and pre-pregnancy weight was lower (all P<0.05). The rate of cesarean section in pregnant women with SVT attack was 12/16, and the rate of cesarean section in pregnant women without SVT was 50% (23/46; P=0.051). No pregnant woman had an arrhythmia during delivery. Conclusions:SVT episode in patients during pregnancy most occurs in the third trimester. Patients who are asymptomatic before pregnancy may also have SVT during pregnancy. Pre-excitation syndrome patients with SVT attacks during pregnancy increase adverse pregnancy outcomes. Multidisciplinary comprehensive management could effectively control pregnant women with pre-excitation syndrome, effectively reduce the occurrence of serious arrhythmia risk events during pregnancy, so that most patients could get good pregnancy outcomes.
