舒芬太尼联合压力控制通气在气管异物取出术中的应用效果

目的 观察比较不同剂量舒芬太尼联合高频压力控制通气在婴幼儿气管异物取出术中的麻醉效果。方法 选择2018—2020年于本院行气管异物取出术的患儿90例,使用随机数字表法分3组,每组30例。3组分别给予不同剂量的舒芬太尼:A组0.1 μg/kg,B组0.3 μg/kg,C组0.5 μg/kg。观察比较3组患儿在麻醉诱导前(T0期)、麻醉诱导后(T1期)、插入硬支气管镜(T2期)、异物取出后(T3期)的生命体征变化;记录3组患儿手术相关指标,同时记录发生不良反应例数。结果 B组T2期生命体征更稳定,术中B组的体动次数(1.5±0.7)和C组的体动次数(1.2±0.6)低于A组的体动次数为(2.5±0.6),(P值均＜0.001),C组在T1期和T2期抑制患儿呼吸,血氧饱和度为(91.4±3.5)%和(88.3±2.7)%,均低于A组的(94.5±2.8)%和(92.7±2.2)%(P值均＜0.05),C组需要退出硬支气管镜以维持通气的次数为(1.6±0.6),高于A组的(1.0±0.3)(P＜0.001),而且苏醒时间为(25.4±5.2)min,长于A组(15.6±5.6)min(P＜0.001)。B组手术时间为(15.3±3.7)min,短于A组的(21.2±4.2)min(P值均＜0.001)。结论 婴幼儿气管异物取出术中,静脉注射0.3 μg/kg舒芬太尼联合高频压力控制通气麻醉效果较优。     

肝内胆管癌30例的临床病理特征及预后分析

目的 :探讨肝内胆管癌 (intra hepaticcholangiocarcinoma ,ICC)的临床病理特征及治疗与预后的关系。方法 :回顾性分析 1991～ 1999年山东省立医院、济宁医学院附属医院 3 0例ICC患者病理、临床资料。结果 :ICC比肝细胞癌少见且预后不良 ,手术切除是目前较理想治疗方式 ,影响预后的因素是肿瘤边缘、淋巴结转移与组织病理情况。根治切除术后 1年生存率 5 3 3 % ,3年生存率 3 3 3 %。结论 :根治性切除是最有效的治疗方法。     

I型三磷酸鸟苷环化水解酶在2型糖尿病大鼠

探讨血管内皮功能异常状态下，I型三磷酸鸟苷环化水解酶（GTPCH I）mRNA在2型糖尿病及硫辛酸干预大鼠主动脉中的表达。方法：选择雄性Wistar大鼠35只，随机选择10只作为正常对照组(NC 组)，25只采用高脂饲料喂养8周后，小剂量链脲佐菌素注射诱导建立2型糖尿病大鼠模型(成模21只)，其中10只给予硫辛酸50?mg/kg腹腔注射，作为硫辛酸干预组（LA组），其余11只作为2型糖尿病组（T2DM组）。所有大鼠饲养16周后均处死测定其主动脉舒张功能，并用半定量RT PCR检测主动脉GTPCH I mRNA表达。结果：T2DM组和LA组主动脉的内皮依赖性血管舒张（EDVR）明显减弱，而LA组较T2DM组有明显改善（P＜0.05）。主动脉GTPCH I mRNA的表达在T2DM组下降70.28%，LA组下降26.88％，两组差异具有统计学意义（P＜0.05）。结论：T2DM大鼠离体主动脉EDVR减弱时，主动脉GTPCH I mRNA表达显著下降。硫辛酸可改善EDVR，此作用可能与改善GTPCH I mRNA表达有关。     

Risk management protocol for gastrostomy and jejunostomy insertion in ventilator dependent infants

Gastrostomy, gastrojejunostomy and anti-reflux surgery in infants and children who are chronically ventilator dependent are associated with significant risk of morbidity and mortality. We report outcomes of 22 high risk children who underwent these procedures at our centre. Pre-operative investigations included: overnight oxygen and carbon dioxide monitoring and subsequent optimisation of ventilatory support, echocardiography, video fluoroscopy, and assessment of gastroesophageal reflux. We carried out 24 procedures under general anaesthesia. Twenty-one children used ventilatory support pre-operatively. Median age of first surgical procedure was 18 months (range 3–180). Supplementary feeding was commenced in 20 children prior to procedure, median age 9 months (1–31). Median PICU length of stay was 1 (1–8) days. No children died in the post-operative period. Extubation was possible within 24 h in 87% of cases. Complications included; atelectasis (n = 2), ileus (n = 2), abdominal distension (n = 4) and loose stools (n = 1). We conclude that, in this high risk cohort of ventilator dependent children with predominantly neuromuscular disorders, with careful assessment, operative intervention can be carried out under general anaesthesia, with the child being extubated early back onto their routine ventilatory support and aggressive airway clearance. Additionally this protocol can minimise post-operative complications and is associated with a good outcome in the majority.     

Local suppression of IL‐21 in submandibular glands retards the development of Sjögren’s syndrome in non‐obese diabetic mice

J Oral Pathol Med (2012) 41 : 728–735 Background: The aim of this study was to verify the validity of IL‐21 local suppression in submandibular glands of preventing the development of Sjögren’s syndrome in non‐obese diabetic (NOD) mice and figure out the mechanism. Methods: IL‐21 levels in submandibular glands were suppressed by ductal cannulation of IL‐21 shRNA lentivirus. Then, saliva flow rates (SFR) and histopathologic changes of submandibular glands were measured to assess the severity of disease development. Real‐time PCR, flow cytometry, and immunohistochemistry were used to detect the changes of T helper cells and related cytokines. Results: The reduction in SFRs in NOD mice was significantly alleviated from 9 to 17 weeks of age along with the suppression of IL‐21 in submandibular glands. Lymphocytic infiltration was also milder than control NOD mice. Moreover, the lower level of IL‐21 led to the down‐regulation of follicular helper T (Tfh) cells. Conclusions: Local suppression of IL‐21 in submandibular glands could retard the development of Sjögren’s syndrome in NOD mice. IL‐21 might contribute to the development of B‐cell disorder in Sjögren’s syndrome via Tfh cells pathway.
