本研究旨在研究鼠伤寒沙门氏菌脂多糖(Salmonella LPS)诱导的雏肉鸡胸腺应激反应,构建和分析反应不同时期胸腺的转录组,为研究雏肉鸡胸腺的免疫应答机制提供相应的理论基础。在分别给雏肉鸡注射LPS或者生理盐水后0到120 h进行取材和器官指数、组织形态、细胞比例和基因表达的检测。采用TUNEL技术和Formamide-MAb技术检测细胞死亡变化。采用流式细胞术检测胸腺内外T细胞数目变化。借助Illumina HiSeq 2000测序平台获取原始测序数据,然后进行转录组数据分析。采用实时荧光定量PCR(qPCR)验证差异表达基因。结果表明LPS可以诱导雏肉鸡胸腺的急性萎缩,显著增加胸腺细胞死亡数目(P<0.05),但是不改变胸腺的组织形态,以及chT1+和CD4+/CD8+T细胞比例。通过转录组分析,LPS刺激后12、36和72 h雏肉鸡胸腺差异性表达转录本数目分别达到873、536和856个。利用qPCR对随机挑选的10个差异表达基因进行验证,其表达水平与RNA-seq结果一致。通路富集分析揭示鼠伤寒沙门氏菌脂多糖可能通过TLR4-FOS/JUN相关通路来诱导雏肉鸡胸腺的损伤反应。

为阐明TLR4信号通路与脂多糖诱导的雏鸡肝损伤之间的关系,本研究以1日龄科宝肉鸡为研究对象,采用HE染色、免疫组织化学染色、ELISA和Q-PCR等方法研究LPS刺激后肝脏组织结构和肝细胞凋亡的动态变化,同时检测TLR4信号通路相关分子的表达变化。结果显示:LPS刺激后各时间点ALT活性与对照组相比均显著升高,肝脏出现了严重的脂肪变性和坏死症状,并伴有大量的淋巴细胞浸润;LPS刺激后凋亡肝细胞显著增多,肝细胞增殖被显著抑制;LPS刺激后TLR4信号显著增强,下游炎性因子的表达均高于对照组,且表现为抗炎因子和促炎因子的表达失衡。以上研究结果表明,LPS刺激能够通过激活TLR4信号通路促进肝细胞凋亡、抑制肝细胞增殖并导致炎症因子的表达失衡,最终导致肝损伤。

Background: Emergence agitation (EA) is a common phenomenon observed in pediatric patients following general anesthesia. This study aimed to assess the efficacy of propofol and fentanyl in preventing EA and to compare their associated complications or side effects. Methods: This prospective randomized observational comparative study was conducted at Dhaka Medical College Hospital from July 2013 to June 2014. The study aimed to evaluate the effects of propofol and fentanyl on EA in children aged 18 to 72 months undergoing circumcision, herniotomy, and polypectomy operations. Ninety children were included in the study, with 45 in each group. Patients with psychological or neurological disorders were excluded. Various parameters including age, sex, weight, American Society of Anesthesiologists (ASA) class, duration of anesthesia, Saturation of Peripheral Oxygen (SPO2), heart rate (HR), respiratory rate (RR), Pediatric Anesthesia Emergence Delirium (PAED) score, duration of post-anesthesia care unit (PACU) stay, incidence of laryngospasm, nausea, vomiting, and rescue drug requirement were compared between the two groups. Results: Age, sex, weight, ASA class, and duration of anesthesia were comparable between the two groups. Perioperative SpO2 and HR were similar in both groups. However, the PAED score was significantly higher in the fentanyl group during all follow-ups except at 30 minutes postoperatively. The mean duration of PACU stay was significantly longer in the fentanyl group. Although the incidence of laryngospasm was higher in the fentanyl group, it was not statistically significant. Conversely, nausea or vomiting was significantly higher in the fentanyl group. The requirement for rescue drugs was significantly higher in the fentanyl group compared to the propofol group. Conclusion: Both propofol and fentanyl were effective in preventing emergence agitation in pediatric patients undergoing various surgical procedures under sevoflurane anesthesia. However, propo
