若干个变量的分布积(英文)

江苏农学院学报 1990年第4期11卷 1-10页

作者： brian fisher 李程宽英国累斯特大学江苏农学院基础课部

设ρ(x)是定义在[1]中的无穷可微函数,δ_n(x)定义为δ_n(x)=n^me(nx_1)…e(nx_m),x∈R^m。两个分布f和g的乘积定义为序列{fg_n}的中性极限。其中g_n=g*δ_n运用定义,给出了一些乘积结果。

Previous research has shown that adulthood disease can be attributed to stress events that occur during gestation. The objective of the present study was to determine whether maternal stress during late pregnancy, using a bacterial endotoxemia model, causes changes in hippocampal mRNA expression of candidate genes related to hypothalamic-pituitary-adrenal axis(HPAA) regulation in sheep. This study also sought to investigate whether maternal diets supplemented with fishmeal(FM) rich in omega-3 polyunsaturated fatty acids(PUFAs) offer protection to the fetus when subjected to maternal endotoxin stress. Using RT-qPCR, relative mRNA expression was assessed in both fetal lambs and 6-month-old lambs from dams supplemented with soybean meal(SM) or FM and challenged with either endotoxin or saline. From this it was found that fetal mineralocorticoid receptor(MR) gene expression had a tendency to be altered during endotoxin challenge, however, in the 6-month-old offspring, MR and glucocorticoid receptor(GR) gene expression were differently altered across treatment groups. These results suggest that gene regulation within the hippocampus is altered into adulthood by maternal endotoxin stress and that dietary supplementation affects outcome.

Purpose: Ablative options, beyond mastectomy, for large breasted patients with breast cancer include oncoplastic resection via reduction pattern and standard lumpectomy. Oncoplastic resection also entails a contralateral procedure for symmetry and the potential benefit of a superior cosmetic outcome. Our aim was to examine the cost-effectiveness of this treatment strategy comparing it to standard lumpectomy in treating breast cancer patients. Methods: A literature review was performed of the probabilities and outcomes related to treatment of unilateral breast cancer via oncoplastic resection or unilateral lumpectomy. Utility score surveys were used to estimate the quality adjusted life years (QALYs) associated with a successful procedure, additional margins excision and post-operative complications. A decision analysis tree was developed to highlight the more cost-effective strategy. An Incremental Cost-Utility Ratio (ICUR) was calculated. Sensitivity analysis was performed to check the robustness of our data. Results: Oncoplastic resection was associated with fewer positive margins relative to standard lumpectomy (10.0% versus 18%). In cases with positive margins, a greater percentage of oncoplastic resection patients chose a mastectomy compared to the lumpectomy patients (72% versus 19%). Utility scores for a successful operation favored oncoplastic resection (92.6 versus 86.55), but in instances of positive margins, favored the lumpectomy patients (74.2 versus 70.2). Decision tree analysis revealed that oncoplastic resection was more cost-effective with an ICUR of $2609.66/QALY gained. Conclusion: Oncoplastic resection represents a cost-effective strategy for the large breasted patient and provides the surgical team yet another reasonable option for the appropriate patient.
