目的 探讨自体心包膜组织对急性心肌梗死大鼠心脏功能的影响。方法 筛选合格的模型动物随机分为三组:心包去除组:仅去除心包膜;心梗组:前降支结扎法建立大鼠心肌梗死模型3周后仅开胸;移植组:前降支结扎法建立大鼠心肌梗死模型,3周后将心包膜移植于心肌梗死及周边区。实验4周后,通过心动图评价实验动物心脏功能,使用Masson染色检测动物心肌梗死大小,通过免疫荧光评价动物心肌存活率、观察血管新生状况,Western blot检测Caspase-3蛋白/Bcl-2基因表达情况。结果 4周后,心包去除组大鼠的心电图监测结果未见有室性颤动;而心梗组、心梗+移植组均有非致死性室性颤动。相比心梗组,心梗+移植组改善了心功能,降低了心肌凋亡指数,免疫Bcl-2蛋白表达升高,而Caspase-3蛋白表达降低。结论 提示自体心包膜移植不会导致恶性室性心律失常,相对有较高的安全性;并能促进心肌梗死细胞恢复心功能,其改善机制可能与通过修补心室重构途径同时抑制缺血区域细胞凋亡有关。

Objective To explore the effect of autologous pericardial transplantation for treating the myocardial infarction (MI) in experimental rats. Methods 30 SD rats were randomly divided in to three equal parts: Pericardial removal group (PR group): only pericardium tissue was removed; Myocardial infarction group (MI group): the anterior descending branch ligation method established a rat model of myocardial infarction and only opened the chest after 3 weeks. Autologous pericardium transplantation (APT group): After established the MI model of SD rats, 3 weeks later, the autologous pericardial patch was harvested and transplanted to infarcted zone. Four weeks after the surgery, the cardiac function and serum biochemistry were analyzed for all the experimental rats. The cardiac function was evaluated by echocardiography, which the size of the infarction were examined by Masson staining, the survival time of transplanted autologous pericardial and angiogenesis were measured by immunohistochemistry, the protein expressions of Caspase and the gene expressions of Bcl were examined by Western blot analysis. Results 4 week after the 2^nd operation, no ventricular fibrillation was detected in the ECG of PR group. Fatal ventricular fibrillation wasn't detected in the ECG of MI group and APT group. Compared with MI group, APT group improved cardiac function and decreased myocardial apoptosis index(P<0.05),which similar to PR group. APT group has the higher density of angiogenesis at infracted area to MI group but less than that of PR group. PT group had decreased protein expressions of Caspase-3 and the expressions of Bcl-2 were decreased. Conclusion Autologous pericardial transplantation could recover myocardial infarction cells, which will improve the cardiac function in experimental rats with MI.

目的 本研究旨在采用连续气道监测法对患者呼吸力学指标进行动态观察,同时监测脑电双频指数（Bispectral index,BIS）和清醒镇静评分（The Observer's Assessment of Alertness/Sedation Scale,OAA/S）,全面系统地评估右旋美托咪定（dexmedetomidine ,Dex）对患者自主呼吸功能和镇静深度的影响,为Dex临床安全应用提供参考依据。方法 80例患者随机分为四组,Dex 0.5 μg/kg组（D₁组）,1.0 μg/kg组（D₂组）,1.5 μg/kg组（D₃组）和对照组（D₀组）,每组病人20例。麻醉诱导前35min分别静脉泵注Dex或0.9%生理盐水10 mL。记录预先给药前（T0 ）、预处理后5min（T1）、10min（T2）、15min（T3）、20min（T4）、25min（T5）和30min（T6）患者的潮气量（V_T）、分钟通气量（MV）、呼气末二氧化碳分压（P_ETCO₂）、呼吸频率（RR）、第一秒呼出率（FEV₁%）、顺应性环（PV环）、阻力环（FV环）、脉搏氧饱和度（SpO₂）、心率（HR）、平均动脉压（MAP）等呼吸力学参数和循环参数及脑电双频谱指数（BIS）及警觉/镇静评分（OAA/S）,并于T0、T1、T3和T6抽取动脉血行血气分析记录PaO₂、PaCO₂和pH值。结果 与对照组相比,D₁组的V_T、RR、MV、P_ETCO₂、FEV₁%、PaCO₂和SpO₂均无变化（P>0.05）,PV环和FV环形态基本正常;D₂组和D₃组MV分别降低16.9%和27.0%;PaCO₂分别升高11.0%和19.9%;FEV₁%分别下降11.0%和14.9%。四组患者均无发生呼吸暂停,而且所有患者SpO₂均在98%或以上。D₃组自主呼吸的PV环和FV环图形面积明显缩小（P<0.05）。D₁组BIS值均在85以上,OAA/S 4分为65%,镇静满意率低,OAA/S 3分仅20%;D₂组镇静满意率最高,OAA/S 3分达70%,且无出现过度镇静;D₃组有60%患者OAA/S评分小于或等于2。结论 静脉泵注Dex所产生的的镇静效应及其对呼吸力学的影响,随着泵注Dex剂量增大,患者镇静程度加深,虽然SpO₂仍在正常范围,但呼吸会受到一定抑制（PV环和FV环图形面积缩小,PaCO₂ 均上升）,临床推荐静脉泵注Dex剂量为0.5 μg/kg~1 μg/kg以策安全。

Objective The purpose of this study was to observe the dynamic indexes of respiratory mechanics in patients with continuous airway monitoring,and to monitor the Bispectral index （BIS） and the Observer's Assessment of Alertness/Sedation Scale （OAA/S）. We evaluated the effect of dexmedetomidine （Dex） on the autonomic respiratory function and the sedative depth of the patients in a comprehensive and systematic way,so as to provide reference for the clinical safety of Dex. Methods In the study,we randomly divided 80 patients into four groups,Dex 0.5,group g/kg （group D₁）,1 group g/kg （group D₂）,1.5 g/kg group （D₃ group） and control group （D₀ group）. There were 20 cases in each group. At about 35min before anesthesia induction,Dex or 0.9% saline 10 mL was injected intravenously. The following time points were selected： pre- administration （T0）,pre-treated 5min （T1）,pre-treated 10min （T2）,pre-processed 15min （T3）,pre-processed 20min （T4）,pre -treated 25min （T5） and pre-treated 30min. The following experimental parameters were recorded at the above time point： tidal volume （VT）,minute ventilation （MV）,end expiratory carbon dioxide partial pressure （P_ETCO₂）,respiratory frequency （RR）,first second exhalation rate （FEV1%）,compliance ring （PV ring）,resistance ring （FV ring）,pulse oxygen saturation （SpO₂）,heart rate （HR）,and respiratory mechanics parameters and circulatory parameters such as mean arterial pressure （MAP）,bispectral index （BIS） and vigilance / sedation score （OAA/S）. At the same time at T0,T1,T3 and T6,arterial blood gas was extracted,and PaO₂,PaCO₂ and pH values were recorded. Results Compared with the control group,the value of VT,RR,MV,PETCO₂,FEV1%,PaCO₂ and SpO₂ in group D₁ did not change significantly （P>0.05）,and the morphology of PV ring and FV ring were basically normal. In group D₂ and group D₃,MV decreased by 16.9% and 27% respectively;PaCO₂ increased by 11% and 19.9% respectively;FEV1% decreased by 11% and 14.9% respectively. No apnea occurred in the four groups,and all patients had SpO₂ at 98% or above. The area of PV rings and FV rings of spontaneous breathing in group D₃ was reduced （P<0.05）. The BIS values in group D₁ were above 85,OAA/S 4 was 65%,sedative satisfaction rate was low,20% patients had a score of 3 in OAA/S;group D₂ had the highest sedative satisfaction rate,70% of patients had a score of 3 in OAA/S,and no excessive sedation;60% of patients in group D₃ with an OAA/S score that was less than or equal to 2. Conclusion The sedation effect that was caused by intravenous infusion of Dex and its effect on respiratory mechanics are as follows： with the increase of Dex's dose,the degree of sedation is deepened. Although SpO₂ is still in the normal range,the respiration will be restrained （the area of PV ring and FV ring is narrowed,the value of PaCO₂ is increased）,and the clinical recommendation of intravenous infusion Dex is at a dose of 0.5µg /kg~1µg /kg for safety reasons. .
