Fisher判别分析在预测异位妊娠中的价值探讨

Objective To discuss the value of Fisher discriminant analysis of serum progesterone and the growing rate of β-human chorionic gonadotropin in the prediction of early ectopic pregnancy. Methods 66 patients with ectopic pregnancy (11 cases were successfully treated expectantly and 55 cases were treated surgically including 40 cases of rupture of fallopian tube and 15 cases of tubal abortion) and 55 patients with intrauterine pregnancy and 50 patients with threatened abortion were chosen. Serum progesterone,β-HCG,48 hβ-HCG and the 48 h growing rate of β-HCG in each group were measured and a Fisher discriminant analysis was used. Results The serum progester-one was (30.27± 18.20) nmol/L in ectopic pregnancy group,( 108.44±23.27 ) nmol/L in intrauterine pregnancy group and (91.68±34.90) nmol/L in threatened abortion group. The first β-HCG was ( 3767.63 ± 3530.38 ) U/L in ectopie pregnancy group,(29 028.65 ± 10 874.01 )U/L in intrauterine pregnancy group and (13 457.47±16 367.65)U/L in threatened abortion group. The second β-HCG was (4349.24±3536.22)U/L in ectopic pregnancygroup,(56 139.46 ± 23 296.87 ) U/L in intrauterine pregnancy group and (23 270.63 ± 23 811.68 ) U/L in threat-ened abortion group. The growing rate of β-HCG ( β-HCG/the first serum β-HCG) was 1.29 ± 0.28 in ectopic preg-nancy group,1.93 ± 0.36 in intrauterine pregnancy group and 1.97±0.28 in threatened abortion group. There was significant difference in serum progesterone,the first β-HCG and the second β-HCG as well as the growing rate of β-HCG among the groups(P<0.05 or <0.01). Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG were connected with diagnosis of ectopic pregnancy,however,the only one serum β-HCG was not con-nected with diagnosis of ectopic pregnancy. 98.5% of ectopic pregnancy,65.6% of intrauterine pregnancy and 64.0% of threatened abortion were correctly classified in the Fisher discfiminant analysis,with overall correct rate of 77.8%. Conclusion Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG can bet-ter predict the early ectopic pregnancy.

上海地区人群血清骨转换标志物参考区间的建立

Objective To establish the reference intervals of serum osteocalcin (OCN), C-terminal cross-linking telopeptide of type Ⅰ collagen (β-CTx) and total type Ⅰ procollagen N-terminal peptide (P1NP) by electrochemiluminescence assay. Methods According to the Clinical and Laboratory Standards Institute (CLSI) "CA8-A" document the appropriately healthy people, who were divided into three groups (men, premenopausal women, and postmenopausal women) by sex and pre- or postmenopausal status were screened. The levels of fasting serum of OCN,β-CTx, tPINP were detected by Roche Modular E170 electrochemical immunoassay. Results 393 appropriately healthy people consists of 112 men between the ages of 29 and 69 years, 148 premenopausal women between the ages of 29 and 69 years, 133 postmenopausal women between the ages of 29 and 69 years. The levels of serum OCN, β-CTx, tP1NP in men group were (15.33±4.76) μg/L, (413±189) ng/L, (42.15±17.14) μg/L, respectively. The levels of serum OCN, β-CTx, tP1NP in premenopausal women group were (12.99±4.53) μg/L, 265(30-820) ng/L, (36.43±14.23) μg/L, respectively. The levels of serum OCN, β-CTx, tP1NP in postmenopausal women group were (18.96±5.15) μg/L, (513±195) ng/L, 51.40 (8.98 -118.6)μg/L, respectively. Logarithmic transformation produced normal distributions for all markers but serum β-CTx of premenopausal women group and serum tPINP of postmenopausal women group. The 95% of the distribution intervals for serum OCN, β-CTx, tP1NP in men group was 6.00-24.66 μg/L, 43-783 ng/L, 9.06-76.24 μg/L, respectively. The 95% of the distribution intervals for serum OCN, β-CTx, tP1NP in premenopausal women group was 4.11-21.87 μg/L, 68-680 ng/L, 8.53-64.32 μg/L respectively. The 95% of the distribution intervals for serum OCN, β-CTx, tPl NP in postmenopausal women group were 8.87-29.05 βg/L, 131-900 ng/L, 21.32-112. 80 μg/L, respectively. Conclusions Compared with the reference intervals provided by manufacture, the reference intervals of three serum bone turnover markers established by our laboratory have great difference. Laboratory should pay attention to the reference intervals was cited.     

The characteristics of interpretation of results of analysis of protein amount in urine of pregnant women

The adequacy of implementation of present proteinuria diagnostic thresholds under examination of pregnant women was examined. The analysis was applied to all urine samples of pregnant women from December 2009 to March 20010. The amount of protein in urine was concurrently evaluated by turbidimetric analysis with sulfosalicylic acid, colorimetric analysis with pyrogallol red, "dry chemistry" technology (the diagnostic strips). It is established that the mentioned techniques of analysis of protein in urine provide independent results. The results of colorimetric analysis are characterized by better precision and adequacy. However, in case of pregnant women the diagnostic threshold of protein concentration should be shifted from 0.120 to 0.150 g/l.     

超声评价放疗对颈动脉溃疡斑块形成的影响

目的 探讨超声在评价放疗对颈动脉溃疡斑块形成的影响的价值。方法 回顾性收集经病理学证实为头颈部肿瘤、放疗前后的颈动脉超声资料以及其他基线资料完整的患者93例,比较放疗前后放疗侧颈动脉和非放疗侧颈动脉粥样硬化斑块和溃疡斑块的总数量、平均内膜-中膜厚度、最大斑块面积、最大溃疡斑块的面积、最大溃疡口的面积。结果 放疗前后颈动脉超声检查的平均间隔时间为（6.1±1.9）年;放疗前放疗侧斑块总数量、平均内膜-中膜厚度、最大斑块面积、溃疡斑块的总数量、最大溃疡斑块的面积、最大溃疡口的面积与非放疗侧比较差异均无统计学意义（P均>0.05）;放疗后放疗侧斑块总数量、平均内膜-中膜厚度、最大斑块面积、溃疡斑块的总数量、最大溃疡斑块的面积、最大溃疡口的面积均较非放疗侧加重,差异有统计学意义（P均<0.05）。结论 放疗可导致头颈部肿瘤患者颈动脉粥样硬化斑块的形成和进展,且斑块具有易损性特点。

超声诊断主动脉窦瘤

本文报告31例主动脉窦瘤患者,全部用二维超声(2DE)和多普勒超声检查。其中手术治疗24例,超声符合22例,符合率为92％。误诊2例,误诊率为8％。故超声实际诊断主动脉窦瘤29例中右冠窦瘤18例(62％),无冠窦瘤7例(24％),二叶瓣型主动脉窦瘤4例(14％)。窦瘤破入/膨入右室和右房内的例数分别为16例和13例。本病主要的合并症为主动脉瓣关闭不全和室缺。通过分析我们认为二维加多普勒超声是诊断主动脉窦瘤最有价值的无创技术。
