肾窦内肾盂加肾后下部切开取石术对肾血流动力学的影响

目的探讨肾窦内肾盂加肾后下部切开取石术对肾内血流动力学的影响. 方法应用彩色多普勒血流显像连续观察98例复杂性肾结石患者术前及术后1、3、6个月肾内及切口区域血流动力学变化,对比分析肾内主肾动脉、段间动脉、叶间动脉收缩期峰值流速(S)与舒张期末流速(D)的比值(S/D)和阻力指数(RI),并将区域血流信号分为Ⅰ～Ⅳ级观察. 结果肾内血流动力学变化与肾积水程度相关(P<0.05,r=0.82),手术对肾内血流动力学指标影响不明显(P>0.05),但对切口区域则造成短期局限性血流障碍,多表现为Ⅲ～Ⅳ级血流信号,一般3～6个月后逐渐恢复,恢复时间长短与结石合并肾积水程度相关. 结论肾窦内肾盂加肾后下部切开取石术是治疗复杂性肾结石的一种安全有效的方法.

胃下部癌D2清除术的标准化与规范化

由于胃癌根治术后五年生存率至今仍不理想,因此,对综合治疗的研究已成为当前临床外科治疗的新热点。自１９８９年以来,我科开展的“胃癌围手术期术前区域性动脉灌注化疗 胃癌根治性手术(Ｄ２清除术或以Ｄ２ 清除术为主) 术中、术后早期腹腔化疗”三联序贯综合治疗方案(ＳＴＴＳ),对提高根治性切除率、降低肝和腹膜复发转移率、延长生存期已取得了较为满意的效果。但在综合治疗方案中,标准、规范化的胃癌根治性切除术和胃周区域性淋巴结清除术仍是关键和基础,是任何化疗或生物、免疫治疗所不能替代的。一、Ｄ２清除术在胃癌根治术中的地位在…

Aging-related Changes of Microglia and Astrocytes in Hypothalamus after Intraperitoneal Injection of Hypertonic Saline in Rats

Hypothalamus is a veryi mportant areain cen-tral nervous system, which takes part in the regu-lation of osmotic pressure . There are many kindsof neurons in this location that are involved in thesynthesis and the release of vasopressin and main-tain the balance of inner osmotic pressure by regu-lating the function of kidneys .It was reported thatmany neurons in hypothalamus showed aged-relat-ed change as a result of the alteration of osmoticpressure .But it remains unclear whether the neu-rogl…     

小儿高热的护理体会

小儿患病最常见的症状就是发热。一般来说，体温在37．5℃～38℃为低热，38．1℃～39℃为中等度热，39．1℃～40℃为高热，40℃以上为超高热。发热系丘脑下部体温调节中枢及散热中枢相对平衡关系发生障碍所致。发热有急性与慢性之分。凡发热在2周以内者为急性发热。2周以上者为慢性发热。对待小儿发热重在护理，必要时才用药。采取适当的护理措施对临床治疗尤其重要。

Effects of Zuogui Wan on neurocyte apoptosis and down-regulation of TGF-β1 expression in nuclei of arcuate hypothalamus of monosodium glutamate -liver regeneration rats

AIM: To inquire into the effects and mechanism of Zuogui Wan (Pills for Kidney Yin) on neurocyte apoptosis in nuclei of arcuate hypothalamus (ARN) of monosodium glutamate (MSG)-Iiver regeneration rats, and the mechanism of liver regeneration by using optic microscope, electron microscope and in situ end labeling technology to adjust nerve-endocrine-immunity network.METHODS: Neurocyte apoptosis in ARN of the experiment rats was observed by using optic microscope, electron microscope and in situ end labeling technology. Expression of TGF-β1 in ARN was observed by using immunohistochemistry method.RESULTS: The expression of TGF-β1 in rats of model group was increased with the increase of ARN neurocyte apoptosis index (AI) (t = 8.3097, 12.9884, P&lt;0.01). As compared with the rats of model group, the expression of TGF-β1 in rats of Zuogui Wan treatment group was decreased with the significant decrease of ARN neurocyte apoptosis (t = 4.5624, 11.1420, P&lt;0.01).CONCLUSION: Brain neurocyte calcium ion overexertion and TGF-β1 protein participate in the adjustment and control of ARN neurocyte apoptosis in MSG-liver regeneration-rats. Zuogui Wan can prevent ARN neurocyte apoptosis of MSG-liver regeneration in rats by downregulating the expression of TGF-β1, and influence liver regeneration through adjusting nerve-endocrine-immunen etwork.
