佩尔地平治疗妊娠高血压病人的护理管理路径

目的探讨护理管理路径在应用佩尔地平治疗的重度子痫前期病人的效果，以期达到最佳的治疗效果，并减少并发症的发生。方法将用佩尔地平针治疗的重度子痫前期的病人486例随机分为两组，一组按常规护理，另一组按制定的护理管理路径护理。结果患者依从性对照组为168例，占70％；观察组为228例，占92．68％，P〈0．05，其差异有统计学意义。胎死宫内发生率对照组为9．16％，观察组为0．81％，P〈0．05，其差异有统计学意义。血压的稳定性对照组为36．3％，观察组为97．6％，P〈0．05，其差异有统计学意义。结论护理管理路径可以提高重度妊娠高血压疾病的治疗效果，减少并发症的发生。     

缺锌对大鼠力竭性游泳前后睾酮和锌水平变化的影响

本实验动态观察了缺锌和缺锌后补锌对大鼠力竭性游泳前后辜丸和血清睾酮、锌水平以及游泳能力的影响。结果显示：缺锌造成大鼠游泳能力大大降低，补锌后明显增加。不论安静时还是力竭性游泳后１２小时内，缺锌大鼠的血清和辜丸锌含量均显著低于对照和补锌大鼠。与对照和补锌大鼠相比，缺锌大鼠的血清和睾丸酮含量，安静时均较低，力竭性游泳后也呈现不同程度的降低。缺锌还造成大鼠辜丸重量的明显下降。结果表明，锌营养不良将损害运动能力。     

亚硝酸钠与AFB1相互作用对遗传物质影响的实验研究

以正常人外周血淋巴细胞的ＳＣＥ率作为细胞遗传学指标，研究了Ｎａ＿２ＳｅＯ＿３与ＡＦＢ＿１相互作用对细胞遗传物质的影响。结果表明，一定浓度的Ｎａ＿２ＳｅＯ＿３（１０￣（－５）ｍｏｌ）对ＡＦＢ＿１所诱发的ＳＣＥ有明显的抑制作用，但当浓度达到１０￣（－２）ｍｏｌ时，细胞增殖受到抑制，到１０￣（－１）ｍｏｌ时细胞出现毒性现象。提示Ｎａ＿２ＳｅＯ＿３具有抑变和细胞毒性双相作用。所以在Ｎａ＿２ＳｅＯ＿３与ＡＦＢ＿１相互作用的ＳＣＥ实验中应避免Ｎａ＿２ＳｅＯ＿３的浓度过高而损伤培养的细胞。     

示波极谱法测定环境中痕量叶蝉散

本文研究了叶蝉散的水解产物邻异丙基酚在硼酸-NaOH－EDTA底液中与MBTH偶合生成物，在电位-0.35V（VS、S、C、E）处的极谱行为，加入等体积的乙醇可提高方法灵敏度和稳定性。方法灵敏度高，较比色法高一个多数量级；线性范围广，0．04～1．5PPm与峰高成正比；合并变异系数4.1％；平均回收率96％～99．2％；方法操作简便、快速，干扰少；样品分析结果与比色法无差异。     

Treatment of hemophilia A by living mother-to-son splenic transplantation. First case report in the world.

A case of severe hemophilia A was treated by living mother-to-son splenic transplantation. The recipient was a 9-year-old boy. After splenic transplantation, the level of blood factor VIII:C was increased, and no spontaneous hemorrhage occurred. The boy was followed up for over two years. This is a case of spleen allotransplantation with the longest function in the world.

     

In situ hybridization of prostate-specific antigen mRNA in human prostate.

Prostate-specific antigen (PSA) mRNA was detected by in situ hybridization utilizing a 428 base pair [35S]-labelled cDNA probe from the 3' noncoding region of the PSA gene. Thirty six fresh surgical specimens were collected from patients undergoing radical retropubic prostatectomy for carcinoma of the prostate. Quantitative analysis of the levels of PSA mRNA in both the benign and malignant tissues was performed using an IBAS 2000 Image Analysis System. The results of this study demonstrated that there is a significant decrease in the expression of PSA mRNA in the carcinoma tissue when compared to the benign epithelium. The average binding (number of silver grains/1 x 10(4) microns. 2) for 20 specimens of malignant epithelium was 475 +/- 161 and 586 +/- 140 for 16 specimens of benign epithelium (p less than 0.05). Eleven patients had both benign and malignant tissue from the same surgical specimen available for study. From these paired specimens, the PSA mRNA expression was also significantly reduced in the malignant epithelium when compared to the benign epithelium, 445 +/- 162 and 588 +/- 135 respectively (p less than 0.005). The PSA protein was detected using a monoclonal antibody to PSA with an immunohistochemical staining technique. The PSA protein expression paralleled the expression of the PSA mRNA in the majority of the tissue sections. Many of the tumor specimens showed a heterogeneous expression of PSA, whereas all of the benign epithelium had a uniform high level of PSA expression. In conclusion, PSA mRNA and protein are located only within the glandular epithelial tissue, the expression of PSA protein parallels that of the PSA mRNA, and both the PSA protein and PSA mRNA are significantly decreased in the malignant epithelium when compared to benign prostatic epithelium.
