The Rh(D) negative patients received the transfusion of CSRBC or whole blood stored at -80 ℃ for 180 to 360 days. The changes in the indexes, such as blood TB, DB, K +, Na +, BUN, Cr, urine protein (URPO), UOB, Hb, HCT, serum total protein, relative to hemolytic reaction and blood volume before and after transfusion were observed. The results showed that after transfusion of CSRBC or whole blood 27 cases were negative for urine protein and UOB, and the levels of BUN and Cr were normal (P>0.05). Blood TB, DB, Hb, and HCT were increased, while pH, blood K + and blood Na + was normal with the difference being not significant before and after operation (P>0.05). Plasma protein was decreased, but there was no significant difference before and after operation (P>0.05). It was suggested that CSRBC or whole blood at -80 ℃ could be safely infused to the Rh(D) negative patients without side effects during the surgical operation.展开更多
R H是目前44个人类红细胞血型系统中除ABO血型外,最复杂、最富多态性的血型系统,D抗原是其中免疫原性最强的,红细胞上无D抗原为RHD阴性(简称RH-)血型。RH-人群的比例差异较大,欧美人群约占15-17%,非洲人群约占3-10%,我国及其他东南亚人...R H是目前44个人类红细胞血型系统中除ABO血型外,最复杂、最富多态性的血型系统,D抗原是其中免疫原性最强的,红细胞上无D抗原为RHD阴性(简称RH-)血型。RH-人群的比例差异较大,欧美人群约占15-17%,非洲人群约占3-10%,我国及其他东南亚人群比例少约占0.3-0.4%。RH-在我国虽属稀有血型,但根据其人群的分布特点和遗传规律,我国的RH-孕妇分娩RH+胎儿的概率反而极高;且随着我国近年来多胎生育政策的逐步开放,RH-妇女再次妊娠率逐年增加,RH-血的用血需求也相应增加。上述情况增加了母婴RH血型不合的风险,进而增加了胎儿/新生儿免疫溶血性疾病 (简称HDFN)的风险,HDFN发病早、进展快、病情严重、并发症风险高,严重威胁围产儿的生命健康、影响患儿远期生活质量,因此规范RH-孕产妇的围孕期管理尤为重要。但目前我国尚无统一、权威的管理指南,故本文综合了国内外相关文献,总结了围产保健方向的RH-孕产妇的围孕期管理规范要点,供临床产科医生参考,以降低HDFN发生率、围产儿死亡率、提高母婴保健质量。展开更多

Here, in the second paper, we continue to analyze each of the four-dimensional vectors of velocity, acceleration, momentum, and forces on the total space-time fabric. According to the approach followed in the first paper. As a result, in the special case, we obtain new transformations for each of the velocity, acceleration, momentum, energy, and forces specific to each subspace-time, which are subject to the positive and negative modified Lorentz transformations described in the first paper. According to these transformations, momentum remains a conserved quantity in the positive subspace and increases in the negative subspace, while the relativistic total energy decreases in the positive subspace and increases in the negative subspace. In the general case, we also have new types of energy-momentum tensor, one for positive subspace-time and the other for negative subspace-time, where the energy density decreases in positive subspace-time and increases in negative subspace-time, and we also obtain new gravitational field equations for each subspace-time.展开更多
