【摘要】 目的 观察胎羊宫内心脏介入手术胎羊血气及血浆炎性细胞因子的变化。方法 8只怀孕双胎山羊,双胎之一为实验组,在相同麻醉条件下,实验组进行胎羊心脏介入治疗,并抽取血样标本。监测胎羊的心率、血气、乳酸值,运用ELISA法检测治疗组及对照组胎羊白介素(IL)1、IL6、IL8及肿瘤坏死因子(TNFα)。结果 2只胎羊因手术中发生心包填塞死亡,存活的6只胎羊手术前pH值较手术后有明显下降(Plt;005),手术前后乳酸浓度上升(Plt;005),PCO2、PO2差异无统计学意义(Pgt;005),手术前血浆IL1、IL6、IL8的浓度较手术后高(Plt;005),手术前后TNFα的浓度变化无统计学意义(Pgt;005)。结论 胎羊宫内心脏介入手术可引起胎羊血浆pH值下降,乳酸浓度上升,及细胞因子IL1、IL6、IL8浓度上升。【Abstract】 Objective To observe the change of blood gas and inflammatory cytokines during intrauterine cardiac intervention surgery on the fetal lambs. Methods Eight pregnant goats with two fetal in each goat were included. With the same anesthesia condition, one of the twin fetus was chose to perform the intrauterine cardiac intervention surgery. The fetal heart beating rate was monitored, and blood samples of the fetus were taken to do the blood gas analysis and to detect the concentration of inflammatory cytokines (IL1, IL6, IL8, and TNFα). Results Two of the eight fetal lambs which was died in the operation because of pericardial tapenade. In the other six survived fetus, the PH was lower than after the surgery, and the concentrations of lactic acid, IL1, IL6, and IL8 are higher than after the surgery. There was no significant difference of PCO2,PO2 and TNFα between before and after the surgery. Conclusion The intrauterine cardiac intervention surgery can make the PH of fetal plasma lower and the concentrations of lactic acid and IL1, IL6, IL8 higher.
目的 明确异丙酚对于高血压脑出血患者血清炎性细胞因子的影响。 方法 将2008年3月-2009年3月收治的高血压脑出血患者47例分为两组，异丙酚组采用异丙酚、芬太尼、维库溴铵以及异氟醚诱导和维持麻醉；对照组采用依托咪酯、芬太尼、维库溴铵以及异氟醚诱导和维持麻醉。比较两组患者手术中不同时段血清白细胞介素（IL-6）、肿瘤坏死因子（TNF）、血栓素、内皮素、前列腺素E和降钙素水平。 结果 患者麻醉过程中生命体征平稳，无麻醉相关死亡。术前异丙酚组患者血清IL-6、TNF、血栓素、内皮素、前列腺素E和降钙素水平与对照组比较均无差异(P＞0.05)，而麻醉诱导后差异有统计学意义(P＜0.05)，而且差异随时间延长增大。 结论 采用异丙酚麻醉能降低术中血清炎性细胞因子水平。
【摘要】 目的 探讨细菌性胶原酶对创口感染情况的影响。 方法 2006年11月-2006年12月，对28只新西兰兔分为实验组和对照组，分别予细菌性胶原酶溶液及生理盐水浸润创口并缝合。观察创口感染及局部皮肤的炎性细胞浸润情况。 结果 实验组与对照组创口感染率差别无统计学意（Pgt;0.05），炎性细胞差别无统计学意义（Pgt;0.05）。 结论 细菌性胶原酶在创伤修复过程中不能直接降低感染率，对炎性细胞的迁移并无明显的作用。 【Abstract】 Objective To assess the effects of bacterial collagenase on the wound infection. Methods A total of 28 New Zealand rabbits have chosen from November to December 2006, and were divided into a laboratorial group and a control group. We sutured the wounds and soaked them by the bacterial collagenase liquid or by the physiologic saline solution. The infection and the inflammatory cells of the skin around the wound were observed. Results The difference of the infection rates between the two groups was not statistically significant (P=0.62), nor the difference of inflammatory cells (P=0.84). Conclusions Bacterial collagenase can not decrease the rate of infection directly, and had no obvious effect on the transferring of inflammatory cells.
Objective To explore the effect of IL-10 on the inhibition of early proinflammatory cytokine release in intraabdominal infection and early sepsis. Methods Forty eight SD rats were randomized into 4 groups, 12 in each group, ①sham operation group, ②control group, ③prophylactic group, ④therapeutic group. Group 1 underwent laparotomy only, group 2 received laparotomy and cecal ligation plus punctures (CLP) with saline injected once every 3 hrs, group 3 underwent CLP and IL-10 injection intraperitoneally 1 hr before surgery and once every 3 hrs following operation, group 4 received CLP and IL-10 injection once every 3 hrs after operation. At 3 and 9 hr points, rats were sacrificed and blood samples were taken for measurement of inflammatory cytokines. Results Almost no inflammatory cytokines were detected in sham group, CLP produced a significant rise in serum TNF-α (tumor necrosis α), IL-1, IL-6 (interleukin 1,6) in control group, IL-10 reduced the rise of inflammatory cytokines significantly. Conclusion IL-10 could inhibit the early inflammatory cytokine release in rat model of sepsis. Suggesting it may attenuate the severity of inflammation.
ObjectiveTo explore the inhibition action of valproic acid to inflammatory cells and smooth muscle cells then to find out that valproic acid (VPA) can repress rat thoracic aortic aneurysm or not. MethodsThe model of rat thoracic aortic aneurysm was built through the method of soaking the adventitia of artery using porcine pancreatic elastase (PPE). The rats were divided into three groups:a normal saline blank control group (a C group), an adventitia soaked PPE group (a P group), and adventitia soaked PPE plus intraperitoneal injection by injecting intraperitioneal VPA 200 mg/kg for seven days (a PV group).The animals of the three groups were all using vascular ultrasound to detect blood vessel diameter. Animals were killed after operation to observe the general morphology of vascular aneuysm and do the immunohistochemial, morphological, protein analysis of interleukin 1 (IL-1), interleukin 6 (IL-6), smooth muscle 22 alpha (SM22α), matrix metallopeptidase 2 (MMP-2), MMP-9 and Western blot by drawing animals on the 14th day. ResultsThe vessels diameter in the PV group was narrower than that in the P group (P value<0.05). HE staining, immunohistochemistry and Western blot displayed that the cells in the P group were in disorder arrangement and interstitial disorder while the cells in the PV group maintained better albumin layer. The protein expressions of IL-1, IL-6, MMP-2, and MMP-9 in the PV group decreased except that SM22α increased. ConclusionVPA can inhibit phenothpic transforming of aneurysm inflammatory cells and smooth muscle cells, reduce the levels of cell proliferation, decrease the secretion of matrix metalloproteinases, and depress tumor growth of rat thoracic aorta.
