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.

目的探讨医源性胆道损伤的预防和处理。方法回顾分析22例医源性胆道损伤的原因及治疗方法。结果行胆管空肠Rouxy吻合11例、胆管对端吻合4例、胆管修补2例、胆道引流或单纯腹腔引流5例;1例LC致胆总管损伤胆漏,中毒性休克死亡,1例CC术后腹腔引流的多脏器功能衰竭死亡,其余均治愈。结论医源性胆道损伤的原因较多,应尽早发现,及时处理。     

中抗褐稻虱稻种抗性鉴定方法的研究

采用改良苗期群体筛选法,可将对褐稻虱具中抗水平的栽培稻和野生稻与感虫稻种区分开来。但如接虫量过大,则中抗稻种会被评为感虫。此外,当采用植株损害系数评价耐害性时,可用植株生长速率来代替原公式中的植株干物质比率。本法可提高工效,并且不会伤害植株,有利于抗虫品种的后代选育。     

水稻中抗品种抗褐稻虱机制的研究

褐稻虱在中抗水稻品种上的刺探频率低于抗级品种。虽然褐稻虱在中抗品种上能正常取食,但同化利用率较低。中抗品种受害后,无论是植株损害系数、光合作用强度降低程度或产量损失率均显著较感虫品种的少,说明了受害后较之感虫品种具有较强的补偿能力。另外,水稻品种受害后呼吸强度均较健株的明显降低。     

战斗应激反应评估与防治策略

战斗应激反应(combat stress reaction,CSR)所导致的非战斗减员一直是现代战争所面临的突出问题,甚至会成为敌方实施主动心理战的手段,在作战样式和战略战术不断更新的背景下，平时心理韧性和调节技巧的训练,战时心理急救的评估和干预，战后严重精神创伤障碍的预防和治疗等，均需给予持续的关注和研究。本文对战斗应激反应的概念、分类和危险因素进行回顾，在 “就近、及时、期望”处置原则的基础上，立足我军卫勤保障和战救技能特点，系统构建以“战斗动员-战场救治-战后干预”三个阶段为主的基本框架，以及简明心理评估要点，对进一步细化的应对策略和技术提出研究方向，以期在目前专业认知下对CSR的早期预防、科学分类、早期干预、综合康复起到推动作用，为我军战场救治综合能力的提升贡献新理念和新方法。
