Family Caregivers' Subjective Caregiving Burden,Quality of Life,and Depressive Symptoms Are Associated With Terminally Ill Cancer Patients' Distinct Patterns of Conjoint Symptom Distress and Functional Impairment in Their Last Six Months of Life

Context

Family caregivers constitute a critical component of the end-of-life care system with considerable cost to themselves. However, the joint association of terminally ill cancer patients' symptom distress and functional impairment with caregivers' subjective caregiving burden, quality of life (QOL), and depressive symptoms remains unknown.

促血小板生成素对预测脑瘫高危儿的意义

目的探讨缺氧缺血性脑病(hypoxia-ischem ia encephalopathy,H IE)胎儿和H IE新生儿血清中促血小板生成素(Thrombopoietin,TPO)水平与脑损伤的关系,为脑瘫(cerebral palsy,CP)高危儿人群进行早期干预提供监测手段。方法收集23例H IE胎儿和34例H IE新生儿血清以及25例正常胎儿和30例正常新生儿血清,34例H IE新生儿包括11例轻度H IE,8例中度H IE和15例重度H IE。采用双抗体夹心ABC-ELISA法检测H IE胎儿组和轻、中、重H IE新生儿组血清中TPO的水平,并与正常胎儿组和正常新生儿组比较。结果H IE胎儿组和H IE新生儿组TPO分别高于正常胎儿组和正常新生儿组(分别P<0.01,P<0.01),重度H IE组TPO低于轻度H IE组(P<0.05)。结论血清TPO水平与H IE所致脑损伤严重程度有关。脐血TPO检测可为脑瘫高危儿人群进行早期干预提供监测手段。

The molecular and clinical impact of hepatocyte growth factor, its receptor, activators, and inhibitors in wound healing

Wound healing involves a number of cellular and molecular events, many of which are controlled by soluble growth factors. In the process of healing, hepatocyte growth factor, a cytokine known to act as mitogen, motogen, and morphogen, has been postulated to play multiple roles during several stages of this complex biological process. Produced primarily by stromal fibroblasts, hepatocyte growth factor regulates angiogenesis, vascular permeability, cell migration, matrix deposition and degradation, and other biological processes. The current article discusses recent progress in understanding the multiple roles played by this growth factor in tissue repair.     

白细胞介素-8在哺乳动物生殖过程中的作用

白细胞介素-8(IL-8)作为中性粒细胞趋化因子和促血管生成因子,受到人们的重视。研究表明,IL-8促进卵细胞的发育、成熟,诱发排卵;在输卵管和子宫内膜的表达随月经周期而变化;参与胚泡着床和胚胎发育。本文综述IL-8在哺乳动物生殖过程中的重要作用。     

慢性阻塞性肺病患者营养与餐后低氧的关系

目的研究慢性阻塞性肺病(COPD)患者的营养状况与餐后低氧的关系.方法51例COPD急性加重期后的患者连续监测就餐前后SpO2,同时记录饮食情况并换算为各营养素的量.结果营养不良组COPD患者餐后SpO2低于餐前,降低幅度超过3%(P＜0.05),进餐时间相对延长,营养物质摄入减少.SpO2变化与单位体质量总热量的摄入呈负相关(P＜0.05).结论重度COPD患者的营养状况可能与患者进餐后发生的缺氧、低氧血症有关,在营养支持中应考虑采取适当措施干预就餐引起的相关低氧血症的发生.     

心肺复苏后血管紧张素Ⅱ与醛固酮分离现象及意义

目的探讨心肺复苏后患者血管紧张素Ⅱ(AⅡ)与醛固酮(ALD)分离现象及其临床意义。方法以放射免疫法测定60例心肺复苏后患者(A组)和35例健康成年人(B组)血中皮质醇(COR)、AⅡ和ALD的含量。结果(1)A组的COR为(471.54±29.78)nmol/L、AⅡ(97.69±13.35)ng/L、ALD(261.03±34.13)pmol/L均分别显著高于B组的(411.52±21.94)nmol/L、(63.70±9.71)ng/L、(242.91±21.03)pmol/L(P<0.05)。(2)在60例心肺复苏后患者中,低ALD的发生率为35%(21/60),高ALD率为51.67%(31/60)。(3)低ALD组的平均动脉血压(42.26±11.93)mm Hg,非低ALD组(53.59±9.88)mm Hg(P<0.05);低ALD组器官衰竭个数(3.81±0.73)、病死率90.48%、快速型室上性心律失常发生率71.43%(16/21)、快速型室性心律失常61.91%(13/21),均分别高于非低ALD患者组[(2.55±0.69)、51.29%、46.16%和30.77%](P<0.05)。结论心肺复苏后患者中存在AⅡ-ALD分离现象并非罕见,而且病情更严重,预后更差,病死率高。     

Recombinant AAV-mediated HSVtk gene transfer with direct intratumoral injections and Tet-On regulation for implanted human breast cancer

Background  

HSVtk/ganciclovir (GCV) gene therapy has been extensively studied in tumors and relies largely on the gene expression of HSVtk. Most studies, however, have failed to demonstrate any significant benefit of a controlled gene expression strategy in cancer treatment. The Tet-On system is commonly used to regulate gene expression following Dox induction. We have evaluated the antitumor effect of HSVtk/ganciclovir gene therapy under Tet-On regulation by means of adeno-associated virus-2 (AAV-2)-mediated HSVtk gene transfer with direct intratumoral injections in mice bearing breast cancer tumors.
