糖化血清蛋白测定对糖尿病监控临床意义的探讨

目的：对临床确诊糖尿病患同时测定血清葡萄糖(Glu)及糖化血清蛋白(GSP)的含量，观察二的关系，以及糖化血清蛋白水平对于评价近期(2—3周)糖尿病患血糖在体内变化的临床意义进行了观察。方法：血清葡萄糖、糖化血清蛋白测定均采用酶法测定。结果：178例糖尿病患Glu、GSP均正常3l例占17．4％；Glu、GSP均增高107例占60．1％；Glu正常、GSP增高15例占8．43％；Glu增高、GSP正常25例占14％。结论：糖化血清蛋白的含量不受即时血糖的影响，二的变化不成比例性，对评价糖尿病患2～3周病情的控制是一项灵敏可靠的指标，尤其对于住院病人的治疗与监控有一定的意义。     

Sleep complaints and their relation with drug treatment in patients suffering from Parkinson's disease.

The aim of this research was to quantify sleep problems in patients suffering from Parkinson's disease by means of the new Parkinson's Disease Sleep Scale (PDSS) and to correlate such problems with the possible influence of current drug treatment. A total of 70 patients (36 men and 34 women) with a diagnosis of Parkinson's disease were enrolled. Their mean age was 69.7 +/- 8.2 years, and duration of disease was 7.4 +/- 4.8 years. All patients completed the PDSS and the Unified Parkinson's Disease Rating Scale (UPDRS Parts I-IV). Drug consumption and doses were registered. The mean score on the PDSS scale was 109.23 +/- 19.75 and on the UPDRS III scale was 25.24 +/- 11.35. The lowest scores were obtained in Item 3 (sleep fragmentation): 5.53 (2.46); and in Item 8 (nocturia): 5.75 (2.91). There was a weak correlation between the PDSS and UPDRS III (cc = -0.355, P = 0.003), PDSS and UPDRS I (cc = -0.272, P = 0.02), and PDSS and UPDRS IV (cc = -0.416, P < 0.001). Motor conditions, mental state, and drug complications influence sleep quality. Although this effect was significant, it was not of a great magnitude. Dopaminergic drugs did not increase daytime sleepiness. As a whole, sleep quality in patients who took dopaminergic agonists did not differ from that of patients who took levodopa in monotherapy.     

经直肠超声引导前列腺穿刺活检203例临床分析

目的评估经直肠超声引导的前列腺六针穿刺活检在前列腺癌及前列腺其他疾病的诊断和鉴别诊断的价值。方法对指肛检查阳性，血清PSA〉4pg／L及经直肠超声检查前列腺声像图异常怀疑有占位性病变的203人进行经直肠超声引导的前列腺穿刺活检。结果穿刺活检的203例病理结果：良性前列腺增生（BPH）104例占51．24％，前列腺癌（PCa）95例占46．80％，前列腺结核及前列腺平滑肌肉瘤各2例，分别占0．98％。结论经直肠超声引导的前列腺穿刺活检其操作简单，病人痛苦小，并发症少，较安全。在前列腺癌及其他前列腺疾病的诊断与鉴别诊断中有重要的临床价值。     

腹腔内疝的CT表现

腹腔内脏器穿过腹膜或膜突入另一腹腔内间隙称为腹腔内疝（internal abdominal hernias）。最常表现为一段小肠嵌入正常或异常的腹腔内孔道，引起急性小肠梗阻。作为疝口的结构可以是腹腔内的正常解剖结构，如裂孔、隐窝、陷窝等，     

不同脑保护方法中炎症反应对脑组织的影响

目的 通过观察体外循环中采用不同脑保护方法时脑组织中各种炎性细胞因子的变化，探讨脑保护对炎症反应的影响。方法 将18只健康成年杂种犬随机均分为3组：常温体外循环组（normothermic cardiopulmonary bypass，NCPB组），深低温停循环组（deep hypothermic circulatory arrest，DHCA组），深低温停循环＋间断选择性顺行性脑灌注组（intermittent selective antegrade cerebral perfusion，ISACP，DHCA＋ISACP组）。术后检测犬脑组织的含水量，分离并取出海马，制备脑组织匀浆，采用放射免疫法测定白细胞介素-1β（IL-1β）和肿瘤坏死因子-α（TNF—α）的含量。在透射电子显微镜（TE）下检测海马脑组织的细胞形态学变化。结果 DHCA组的IL-1β和TNF—α含量明显高于NCPB组和DHCA＋ISACP组（P〈0．01），但NCPB组与DHCA＋ISACP组间比较差别无统计学意义（P〉0．05）；TNF—α和IL-1β含量与脑水肿的程度呈正相关（r=0．987，0．942；P〈0．01）。TE检查显示DHCA组超微结构破坏较严重，而NCPB组和DHCA＋ISACP组破坏较轻。结论 长时间DHCA会造成脑损伤，DHCA＋ISACP有一定的脑保护作用，IL-1β和TNF—α在长时间DHCA中对脑损伤起一定的作用。     

浅谈网络时代高校大学生思想政治教育工作

当前我们正经历着21世纪跨时空的信息革命，走进了网络信息的时代，网络比以往任何一次技术革命对社会的政治、经济、文化的冲击更强大，它塑造了一种全新的生活和工作状态。正是由于网络信息传播的影响而造成了人类的价值观和思维模式的变化，同时对当今大学生的思想也产生了较大的影响。那么，如何充分运用网络资源和信息技术传播社会主流价值形态和切实加强大学生思想政治教育成为社会关注的问题，也日益成为高校大学生思想政治教育工作者亟待研究和正在解决的重要课题。

Long-term effects of physiologic concentrations of dexamethasone on human bone-derived cells

Bone cells derived from human trabecular explants display osteoblastic features. We examined the modulation of alkaline phosphatase activity and cAMP production as the result of exposing trabecular explants to physiologic concentrations of dexamethasone for 4 weeks during cellular outgrowth and subculture. Cells treated with dexamethasone were observed to grow generally more slowly than control cells. Cells appeared larger and more polygonal, and staining for alkaline phosphatase was more intense in the dexamethasone-exposed cultures. There was a progressive increase in cellular PTH responsiveness with increasing duration of exposure of cells to dexamethasone. Cells grown for 6 weeks in 3 x 10(-8) M dexamethasone had a 10-fold increase in PTH-stimulated cyclic AMP accumulation. Dexamethasone-treated cells also had a significantly increased alkaline phosphatase activity. 1,25-(OH)2D3-stimulated alkaline phosphatase activity was increased approximately 20-fold. cAMP responses were significantly increased to PTH (21.7-fold), PGE1 (2.67-fold), and forskolin (4.81-fold), but not to cholera toxin. Dexamethasone-treated cells also had a mean decrease in 1,25-(OH)2D3-stimulated osteocalcin production to 26.2% of control values (p less than 0.001). Hydrocortisone treatment gave rise to similar effects but of smaller magnitude than those of dexamethasone. Testosterone did not have a significant effect on alkaline phosphatase activity or cAMP production. Skin fibroblasts showed a significant enhancement of alkaline phosphatase activity in response to dexamethasone, but of a much smaller magnitude than in bone cells. The phenotypic changes induced by long-term culture in dexamethasone are consistent with the promotion of a more differentiated osteoblastic phenotype.
