【摘要】 目的 比较靶控诱导后Shikani喉镜、Macintosh直接喉镜和GlideScope®视频喉镜插管时的应激反应。 方法 选取2008年12月-2009年2月期间ASA Ⅰ~Ⅱ级、拟于全身麻醉下行择期颅内占位病变切除术的患者30例，随机分为Shikani喉镜组（S组）、Macintosh直接喉镜组（M组）与GlideScope®视频喉镜组（G组）。靶控异丙酚和瑞芬太尼诱导，分别采用上述3种喉镜行经口气管插管。记录患者的心率、血压，计算心率收缩压乘积（RPP）。 结果 3组插管时间、心率、血压和RPP比较差异无统计学意义（Pgt;0.05）。S组和M组插管后心率、血压及RPP均较插管前显著升高（Plt;0.05），而G组插管后的心率、60~300 s时的收缩压、平均动脉压和RPP与插管前比较，差异无统计学意义（Pgt;0.05）。 结论 3种喉镜进行经口气管插管时具有相似的血流动力学反应，GlideScope®视频喉镜更有利于循环稳定。【Abstract】 Objective To compare the hemodynamic responses of orotracheal intubations with GlideScope® videolaryngoscope, Macintosh direct laryngoscope, and Shikani optical stylet after target-controlled-infusion (TCI). Methods Thirty patients with American Society of Anesthesiologists (ASA) physical status Ⅰ-Ⅱ, scheduled for elective intracranial mass lesion surgery under general anesthesia were randomly allocated equally to Shikani optical stylet group (group S) Macintosh laryngoscope group (group M), and GlideScope® videolaryngoscope group (group G). After the patients became unconscious by TCI induction of propofpol and remifentanil, the endotracheal intubation were carried out through above three laryngoscope. The heart rate (HR), blood pressure and rate pressure product (RPP) were recorded. Results The differences of intubation time, HR, blood pressure and RPP in three groups were not statistically significant (Pgt;0.05). After intubation, the HR, blood pressure and RPP of group S and M were obviously higher than those before intubation (Plt;0.05); while there was no obvious change on the HR, systolic pressure at 60-300 s, mean arterial pressure and RPP of group G compared before intubation (Pgt;0.05). Conclusions There are similar hemodynamic responses in the three laryngoscope. GlideScope® is more advantageous to cycle stability.

Objective To explore the effect of rolling compression loading bioreactor on chondrogenesis of rabbit bone marrow mesenchymal stem cells (BMSCs) with different loading parameters. Methods BMSCs were isolated from New Zealand rabbits, aged 2.5 months. BMSCs at passage 3 were used to prepare BMSCs-agarose gels (4 mm in diameter and height, respectively). Samples were divided into 8 groups: 10% (group A1), 20% (group A2), and 30% (group A3) compression groups (0.4 Hz, 3 h/ d) and 20 minutes (group B1), 3 hours (group B2), and 12 hours (group B3) rolling time groups and static culture (control groups). The living cell rate, the collagen type II and Aggrecan gene expressions, and glycosaminoglycan (GAG) content were determined, and histological staining was done at 24 hours, 7 days, 14 days, and 21 days after culture. Results At 14 and 21 days, the living cell rates of groups A1 and A2 were significantly higher than that of group A3 (P lt; 0.05), groups B1 and B2 were significantly higher than group B3 (P lt; 0.05). Collagen type II and Aggrecan gene expressions of the experimental groups at each time point were significantly higher than those of the control groups (P lt; 0.05); at 14 and 21 days, collagen type II and Aggrecan gene expressions of groups A1 and A2 were significantly higher than those of group A3, and groups B1 and B2 were also significantly higher than group B3 (P lt; 0.05). At 14 and 21 days, the GAG contents of groups A1 and A2 were significantly higher than those of group A3 (P lt; 0.05); groups B1 and B2 were also significantly higher than group B3 (P lt; 0.05). At 21 days, toluidine blue staining showed that obvious blue-staining and even cartilage lacunae were seen in groups A2 and B2, but light and quite rare blue-staining in groups A1, A3, B1, and B3. Conclusion The rolling compression loading bioreactor has great promotion effect on chondrogenesis of rabbit BMSCs with rolling parameters of 0.4 Hz, 3 hours, and 20% compression.

Methods A total of 80 patients who underwent the operation of gastric cancer under general anesthesia from October 2009 to April 2010 were randomly divided into four groups: group Q1 received tramadol 1 mg/kg, group F1 received fentanyl 1 μg/kg, group Q2 received tramadol 2 mg/kg, and group F2 received fentanyl 2 μg/kg. Thirty minutes before the end of surgery, intravenous administration was performed on all of the patients. In the recovery room, the wake-up time, extubation time, pain level evaluated by Visual Analogue Scale (VAS), the mean arterial pressure (MAP), heart rate (HR) and pulse oxygen saturation (SpO2) before and after the surgery, and incidence of complications were recorded. Results No significant differences in wake-up time among the four groups were found (Pgt;0.05). The extubation time was longer in group F2 than that in the other three groups (Plt;0.05). The VAS scores in group Q1 and F1 were higher than those in group Q2 and F2. At the T2 time point, MAP in group Q2 and F2 were lower than those in group Q1 and F1 (Plt;0.05). Conclusion The analgesic efficacy of tramadol 2 mg/kg is similar to that of fentanyl 2 μg/kg, but tramadol is more suitable for analgesic treatment in recovery period after general anesthesia due to the higher security.
目的 阻塞性睡眠呼吸暂停低通气综合征（OSAHS）可引起心血管疾病发生增高，是高血压病及冠心病等的独立危险因素。打鼾是OSAHs的主要临床症状。本研究的主要目的是了解成都地区自然人群打鼾发生情况及其与心血管疾病危险因素的关系。 方法 2007年在成都市成华区采用随机抽样方法对男、女性共711人进行了心血管疾病危险因素调查[年龄45～80岁，平均（3.28 ± 6.25）岁，男性患者占所有患者的57.8%]，主要包括问卷调查、体格检查及血液学检查等，其中打鼾调查主要包括打鼾时间、次数及憋醒情况。将与打鼾相关的3个指标综合考虑后，计算出打鼾的严重程度，并分析了其与心血管疾病危险因素的关系。 结果 男性人群中打鼾率较女性高（62.0%、51.0%，P=0.003），且重度及极重度打鼾率也较女性高。随着打鼾的严重程度增加，体质量指数、血肌酐及尿酸等心血管疾病危险因素逐渐升高（趋势P均＜0.05），而高密度脂蛋白胆固醇逐渐降低（P=0.001）。另外，随着打鼾的严重程度增加，高血压患病率及收缩压也逐渐升高，但无统计学意义（趋势P=0.063，0.08）。 结论 成都地区中老年城镇人群的打鼾率较高，且男性高于女性。另外，随着打鼾的严重程度增加，心血管疾病危险因素也逐渐升高。这提示我们在临床工作中，对于打鼾的患者需要加强心血管疾病危险因素的筛查及干预，以期减少它的发生发展。

Objective To investigate the effect of preoperative rehabilitation on early function of joints after total hip arthroplasty by comparing with non-preoperative rehabilitation. Methods Between March 2010 and November 2011, 98 patients with hip disease were recruited in study. Of 98 patients, 49 received preoperative rehabilitation for 2 weeks in trial group, and 49 did not receive preoperative rehabilitation in control group. There was no significant difference in gender, age, disease duration, disease cause, preoperative visual analogue scale (VAS) score, and preoperative Harris score between 2 groups (P gt; 0.05). Results There was no significant difference in VAS score at each time point after operation between 2 groups (P gt; 0.05), but significant differences were found in Harris score (P lt; 0.05). At 3 days after operation, compliance evaluation results showed that 36 cases were of full compliance, and 13 cases were of partial compliance in trial group; 27 cases were of full compliance, 14 cases were of partial compliance, and 8 cases were of non-compliance in control group; there was significant difference between 2 groups (Z=2.286, P=0.002). The ambulation time was within 7 days in trial group, and was within 7 days in 47 cases and more than 7 days in 2 cases in control group; there was significant difference between 2 groups (Z=3.840, P=0.000). Conclusion Preoperative rehabilitation plays an important role in compliance, decreased bed rest time, and hip function improvement in patients after total hip arthroplasty.
