目的 评价围术期目标导向液体治疗用于老年高危患者的优越性。方法 50例行择期全髋关节置换术的老年患者,随机分成传统液体治疗组(C组)和目标导向治疗组(GDT组),每组25例。C组以MAP和CVP为指导进行围术期液体管理,GDT组以每搏量(SV)和氧供指数(DO₂I)最大化进行围术期液体管理。观察和比较两组患者围术期液体出入量、MAP、HR、SV和CI等参数。结果 GDT组总输液量、晶体液和胶体液的输注总量均高于C组(P＜0.05);GDT组各时点MAP、HR、SV和CI高于C组(P＜0.05),与基础值比较,GDT组无变化,而C组在麻醉后和应用骨水泥后,MAP、HR、SV和CI一过性下降(P＜0.05)。结论 与传统围术期液体管理方案相比,以SV和DO₂I最大化为目标的GDT方案用于高危病人全髋置换手术,能使心脏前负荷处于更理想的充盈状态,血流动力学更稳定,并能有效预防骨水泥引起的循环抑制作用。

Objective To evaluate the priority of goal-directed fluid therapy(GDT) in high risk elderly patients. Methods Fifty elderly patients undergoing total hip replacement were randomly divided into traditional fluid therapy group(group C) and goal-directed fluid therapy group(group GDT). Group C received perioperative fluid management based on MAP and CVP, while Group GDT received goal-directed fluid therapy based on SV and DO₂I optimization. MAP, HR, SV, and CI were recorded at different time points; the intraoperative blood loss, fluid volume, and urine volume were also recorded. Results The total fluid volume, colloid volume and crystal volume of group GDT were much more than group C(P＜0.05); the intraoperative MAP, HR, SV, and CI in group GDT were much higher than group C(P＜0.05); compared withbaseline of MAP, HR, SV, and CI, there were no obvious change in group GDT, while there were significant decline in group C, especially after anesthesia and implantation of bone cements(P＜0.05). Conclusion Compared with traditional fluid management strategy, SV and DO₂I optimization based goal-directed fluid therapy has a significant priority in high risk elderly patients undergoing total hip replacement.It can maintain better preload and provide more stable hemodynamic status, and prevent cardiac side effect induced by implantation of bone cements

Objective To investigate the neuroprotective mechanism of naloxone injected into cisterna magna on cerebral ischemia-reperfusion. Methods Thirty adult male SD rats were randomly divided into sham group, conventional cardiopulmonary resuscitation (CPR) group and naloxone CPR group. Asphyxiation was used to set up rat cardiac arrest model, and corresponding drugs were given when the resuscitation was carried out. The Brain tissues were taken at 24 h after restoration of spontaneous circulation(ROSC). Fluorescence quantitative polymerase chain reaction (PCR) and immunohistochemical was used to detect the expression of c-Fos proteins was used to detect the expression of c-Fos mRNA level. Results Compared with the conventional CPR group, Naloxone could significantly decrease the expression of c-Fos protein and c-Fos mRNA in rat brain. Conclusion Naloxone injected into cisterna magna can promptly and effectively act on c-Fos gene, playing a neuroprotective role.

目的 探讨糖尿病胃轻瘫大鼠不同血糖水平对Cajal间质细胞(ICC)的影响及其机制。方法 选择雌性Wista大鼠60只进行随机分组,实验组40只,对照组20只。实验组糖尿病Wista大鼠模型以单次腹腔注射链脲佐菌素法诱导。免疫组织化学荧光染色检测不同血糖浓度大鼠胃ICC数量及网络结构。结果 实验组大鼠血糖浓度高于对照组,ICC数量,低于对照组,且比较差异有统计学意义(P<0.05)。实验组大鼠中血糖浓度越高,ICC数量越低,说明血糖浓度升高可能与平滑肌及神经末梢之间缝隙连接的减少及其ICC网络的超微结构损伤及异常有关。结论 DM小鼠胃组织中血糖水平的升高,可能是DM胃中ICC数量减少的原因;外源性降低血糖能改善DM相关的胃肠道ICC病变。

Objective To observe the effects of glucose fluctuations on Cajal interstitial cells (ICC) of rats with diabetic gastroparesis(DGP) and its mechanistic. Methods 60 Wistar rats were selected and randomly divided into two groups. 20 rats in experimental group and 40 rats in control group. Used immunofluorescence staining to detect the amount of gastric ICC and network structure in DGP rats with different glucose levels. Results The blood glucose concentration in the experimental group was significantly higher than that in the control group, the amount of ICC in the experimental group was significantly lower than that in the control group(P<0.05). The amount of ICC decreased with the increase of glucose levels. In the experimental group, The gap junctions between smooth muscle and nerve endings, ultrastructural damage and abnormalities of the ICC network were probably related to glucose level. Conclusion The increase of glucose level was probably the cause of the decrease of the amount in ICC. Exogenousy decrease glucose levels probably can help to improve the lesion of ICC with DGP.

Objective To study the effects of PF induced chemotherapy combined with intensity modulated radiation therapy and two-dimensional radiotherapy on the short and long term curative effects in nasopharyngeal carcinoma. Methods The treatment condition of 101 cases of patients with nasopharyngeal carcinoma who were treated in the Tumor Hospital Affiliated to San Yat-sen University between January and December 2008 were retrospectively analyzed. According to different treatments, the cases were divided into the intensity modulated group and the two-dimensional group.
