654─2在小儿急性脑水肿及中枢性呼吸衰竭中的应用探讨

感染性脑水肿病儿在感染得到有效控制，应用654—2（山莨菪碱）后未再用脱水剂，笔者认为．654—2具有解除脑血管痉挛及微循环障碍的作用。急性脑水肿在脱水剂应用后，用654—2有利于脑水肿液的吸收和回流。目前，治疗小儿捂热综合征（IMS）之细胞内水肿仍没有有效的方法，研究结果表明654—2能改善脑细胞供氧．其还能通过解除呼吸中枢血管痉挛而治疗中枢性呼吸衰竭。     

中长跑和芭蕾舞运动中胫骨应力骨折的比较

胫骨应力骨折（ＳＦ）在芭蕾舞和中长跑运动员中均有一定发病率，作者调查某部新兵２６５人每日５０００米跑步，其胫骨应力骨折病发率为１１．６８％（３１／２６５人），骨折部位多在胫骨中段中后侧。芭蕾舞演员胫骨应力骨折病发率为８％（１５／６０人），骨折部位在胫骨下段前侧。应用新鲜尸体标本作负荷下胫骨多处的应变测定模拟跑步和足跟垫高模仿芭蕾舞时下肢负重位置的应变变化，分别于胫骨中段后侧测得有高压应力和胫骨下段前方有高张应力，此结果与调查中Ｘ线片病变部位相符。作者认为不同的运动使负重时胫骨所处姿势各不相同，而造成胫骨最大应力集中点位置各异，是造成芭蕾舞运动和中长跑运动中应力骨折部位不同的主要原因，预防和治疗工作应根据各自的应力性质和集中点部位来进行防治。

Effects of propofol emulsion and thiopentone on T helper cell type-1/type-2 balance in vitro

We have earlier found increased percentages of T helper cells (CD4-positive lymphocytes) in the blood circulation after propofol infusion anaesthesia. Cytokines interferon-γ (IFNγ) and interleukin-4 (IL-4) are important in the differentiation of T helper cells into subtypes T helper type-1 (Th1) and type-2 (Th2). To study the effects of propofol emulsion, its solvent Intralipid^® and thiopentone on Th1/Th2 balance, measurements of IFNγ and IL-4 production by mononuclear leucocytes were carried out in vitro . As IL-2 has a central role in immune responses to surgery, its production was also measured. Concanavalin A-stimulated mononuclear cells were cultured in the presence of propofol emulsion at 3.5 or 10 μg.ml⁻¹, Intralipid^® 35 or 100 μg.ml⁻¹, or thiopentone 3 μg.ml⁻¹. Cytokine production was measured from the conditioned media of mononuclear cell cultures. Decreased IFNγ (p <0.001) and IL-4 concentrations (p < 0.01) were found in the presence of thiopentone, but IL-2 production was unaffected. By contrast, propofol emulsion or Intralipid^® had no effects on IFNγ, IL-2 or IL-4 concentrations. Propofol 10 μ.ml⁻¹ increased the IFNγ/IL-4 ratio from the control value median 243 (162–562) (25th–75th percentile) to 363 (195–1028) (p < 0.01), but thiopentone decreased it to 145 (60–214) (p < 0.01). These findings show that propofol and thiopentone have different effects in vitro on Th1/Th2 balance and suggest that they have different modulating effects on the immune response.

Boundary Ambiguity in Parents With Chronically Ill Children: Integrating Theory and Research

Abstract: This article integrates theory and research related to boundary ambiguity in parents of children with a chronic health condition. We propose that boundary ambiguity is a risk factor for psychological distress in these parents. Clinical applications and a case example highlight how boundary ambiguity can be assessed and managed in clinical settings by professionals working with parents with chronically ill children. Questions are provided for assessing boundary ambiguity in clinical and research settings, and implications for research are discussed.     

Modulation of infection-induced inflammation and locomotive deficit and longevity in senescence-accelerated mice-prone (SAMP8) model by the oligomerized polyphenol Oligonol.

Oligonol is produced from the oligomerization of polyphenols (typically proanthocyanidin from a variety of fruits such as lychees, grapes, apples, persimmons, etc.) and contains catechin-type monomers and oligomers of proanthocyanidins. The ability of Oligonol to affect infection-dependent eye inflammation, locomotion and longevity in senescence-accelerated prone mice (SAMP8) (a model of senescence acceleration and geriatric disorders with increased oxidative stress and neuronal deficit) was investigated. Oligonol (60mg/kg) significantly modulated the extent of inflammation scores in the eye of SAMP8 mice. Examination of the mice indicated infection with mouse hepatitis virus and pinworm (Syphacia obvelata) in both males and females and with the intestinal protozoa (trichomonad) in males. A comparison of the two groups (using log-rank test) and the difference in the mean life span between groups (using Student's t-test) indicated significant differences in survival (p=0.043) and the mean life span (p=0.033) in male SAMP8 mice. Oligonol increased the mean life span and this was statistically significant. In the open-field locomotive test, the 7-week-old SAMP8 mice crossed more than 40 partitioned lines in 1min. At 48-week-old control untreated male SAMP8 crossed 2 lines. The Oligonol-treated 48-week-old male SAMP8 mice crossed 17 lines however. The improved locomotive activity was statistically significant even after 36weeks in the Oligonol-treated male SAMP8 but this was not the case throughout the time course of the study in the Oligonol-treated female SAMP8. Thus Oligonol treatment to SAMP8 mice modulated the severity of infection-dependent inflammation, prolonged life-span and significantly improved locomotive activity indicating potential benefit to aging-associated diseases such as Alzheimer's or Parkinson's diseases. This presents potential for further research to define infection-dependent inflammation associated with degenerative conditions and the molecular mechanism of dietary antioxidant protection.
