目的:分析和研究黄芪桂枝汤对于风湿痹证患者的改善作用。方法:选择了56例患者进行研究主要对象,将所有参与研究的56例患者分成了对照组(28例)和观察组(28例),使用的分组方式为随机数字表法。对照组使用的治疗方式为西药,观察组则在西药治疗的基础之上增加了黄芪桂枝汤进行联合治疗。之后对比两个组别患者的治疗疗效以及疼痛积分值。结果:对照组之中有11例患者为治愈,11例患者为好转,剩余6例患者为未愈;观察组之中有15例患者为治愈,12例患者为好转,剩余1例患者为未愈,对照组之中患者的治疗疗效明显低于观察组之中的患者。在进行治疗之前,对照组与观察组患者之间的对比不具有统计学意义,对照组当中患者的疼痛积分值明显低于观察组患者,P <0.05说明数据的差异存在统计学意义。结论:在对风湿痹证患者进行治疗时,加用黄芪桂枝汤能够起到标本兼治以及扶正祛邪的作用,值得推广。     

Xenogeneic bone marrow transplantation: II. Porcine-specific growth factors enhance porcine bone marrow engraftment in an in vitro primate microenvironment

Abstract: Establishment of mixed bone marrow chimerism in pig-to-primate transplantation, as a means of inducing specific immune tolerance, will require that both immune and nonimmune barriers be overcome. As a preliminary step in evaluating nonimmune barriers in this system, we have developed an in vitro model of engraftment in which long-term culture of porcine bone marrow-derived hematopoietic cells is supported on preformed primate bone marrow stromal layers. In the absence of cytokine supplementation, primate stromal cells were unable to support long-term porcine hematopoiesis in these cultures. Supplementation with porcine Steel Factor was required for long-term maintenance of hematopoietic progenitor cell content and total hematopoietic activity. Addition of porcine IL-3, in combination with porcine Steel Factor, increased long-term progenitor cell content and hematopoietic activity on primate stroma to levels comparable to that obtained in cultures on porcine stroma. The combination of porcine GM-CSF and Steel Factor increased progenitor cell content and hematopoietic activity early in the cultures, but had little effect in long-term cultures. The Steel Factor and IL-3 combination was species-specific in its action in these cultures, as the corresponding human cytokines were unable to effectively support long-term porcine hematopoiesis. Likewise, the combination of porcine cytokines had only minimal effects on long-term bone marrow culture of primate CD34+ cells I on primate stroma.     

衣原体、支原体引起的难治性支气管—肺部感染分析

目的 探讨难治性支气管—肺部感染(难治组)衣原体、支原体两种病原体的表达。方法 应用ELISA法检测了29例难治性支气管—肺部感染两种非典型病原体急性感染指标，衣原体抗体IgM、支原体抗体IgM及冷凝集实验，并常规细菌学检查，与同期住院的普通性下呼吸道感染(普通组)40例，门诊及住院的急性上呼吸道感染(上感组)30例进行比较。结果 难治组衣原体急性感染率68．9％，显著高于普通组、上感组，上感组最低；支原体急性感染率难治组34、5％，显著高于普通组、上感组；衣原体混合支原体、衣原体混合其他致病菌感染均显著高于普通组和上感组。结论 难治性下呼吸道感染中衣原体、支原体感染率较高，且易与多种病原体混合感染，衣原体的慢性感染可能是难治感染的重要原因。     

Immunoregulatory Factor Released From a Cell Line Derived From Human Decidual Tissue

ABSTRACT: The culture supernatant of the TTK-1 cell line, established from human decidual tissue, was found to contain a factor that strongly suppressed the mixed lymphocyte reaction (MLR). The mechanism of the MLR-suppressive activity as well as the biochemical characterization of this factor was analyzed. The TTK-1 supernatant suppressed the MLR much more strongly than the culture supernatants of the three other malignant cell lines examined. The molecular weight of this factor was estimated to be between 43 kilodaltons (kd) and 67 kd by gel filtration chromatography. The TTK-1 supernatant also suppressed the proliferation of the interleukin 2 (IL-2)-dependent T cell lines, but did not suppress that of the IL-2-independent T cell lines, suggesting that the TTK-1 supernatant inhibited the action of IL-2 and subsequently suppressed the MLR. The fact that the TTK-1 cell line originated from human decidual tissue might imply the important role of this factor in immunological fetomaternal balance.     

核磁共振法测定非离子表面活性剂 HLB 值的研究 2.几种混合体系 HLB 值的测定与计算

本文应用核磁共振法(NMR)测定了几种混合体系的 HLB 值与混合体系中各组分的 HLB 值。实验结果表明,混合体系中各组分在核磁共振图谱中的积分曲线高度也具有加和性。混合体系的 HLB 值是体系中各组分 HLB 值的加权平均值。因此,对混合体系的 HLB 值可以应用 NMR 法直接测定,也可应用 NMR 法测定各组分的 HLB值,通过计算求得,计算值与实测值完全一致。     

Fisher information matrix for nonlinear mixed effects multiple response models: Evaluation of the appropriateness of the first order linearization using a pharmacokinetic/pharmacodynamic model

We focus on the Fisher information matrix used for design evaluation and optimization in nonlinear mixed effects multiple response models. We evaluate the appropriateness of its expression computed by linearization as proposed for a single response model. Using a pharmacokinetic–pharmacodynamic (PKPD) example, we first compare the computation of the Fisher information matrix with approximation to one derived from the observed matrix on a large simulation using the stochastic approximation expectation–maximization algorithm (SAEM). The expression of the Fisher information matrix for multiple responses is also evaluated by comparison with the empirical information obtained through a replicated simulation study using the first‐order linearization estimation methods implemented in the NONMEM software (first‐order (FO), first‐order conditional estimate (FOCE)) and the SAEM algorithm in the MONOLIX software. The predicted errors given by the approximated information matrix are close to those given by the information matrix obtained without linearization using SAEM and to the empirical ones obtained with FOCE and SAEM. The simulation study also illustrates the accuracy of both FOCE and SAEM estimation algorithms when jointly modelling multiple responses and the major limitations of the FO method. This study highlights the appropriateness of the approximated Fisher information matrix for multiple responses, which is implemented in PFIM 3.0, an extension of the R function PFIM dedicated to design evaluation and optimization. It also emphasizes the use of this computing tool for designing population multiple response studies, as for instance in PKPD studies or in PK studies including the modelling of the PK of a drug and its active metabolite.
