中西医结合治疗急性冠脉综合征临床疗效观察

目的观察中西医结合治疗急性冠脉综合征（ACS）的临床疗效。方法将60例ACS患者随机分为两组。治疗组在抗血小板、抗凝、降脂、扩张冠状动脉、降压、保护血管内皮功能等常规治疗基础上服用中药复方苏欣康颗粒；对照组在常规治疗基础上加用复方丹参滴丸。2周为1个疗程，1个疗程结束后观察治疗前后临床症状、心电图、24h动态心电图变化，并判定疗效。结果经2周治疗后，治疗组总有效率（90．O％，27／30）显著高于对照组（83．3％，25／30），差异有统计学意义（P〈0．05）。治疗组临床症状的改善程度高于对照组，其中以对心悸、自汗及心肾阳虚的改善最显著（P均〈0．05）。治疗组心律失常发生率（36．7％）低于对照组（50．0％），但差异无统计学意义（P〉O．05）。结论中药复方苏欣康结合常规手段治疗ACS疗效确切，可作为治疗ACS的有效方剂。

小肠浆肌膜腔内自体脾组织移植动物模型的建立与意义

目的探讨增加自体脾组织移植量的方法,提高自体移植脾组织的功能。方法贵州小型香猪3头,经肌注麻醉后剖腹切除脾脏,取脾脏的1/2约150g,切成1mm×1mm×1mm小块备用。在距Treitz韧带50cm处,切取保留肠系膜血管的空肠30cm旷置,再吻合肠管恢复肠腔通道,缝闭肠系膜裂口。旷置空肠等分2段,去除肠粘膜,缝闭一端,将约50g脾组织块分别植于2段肠浆肌膜腔内,缝闭另一端口,妥善固定于肠系膜上。大网膜内移植30g脾组织作为对照观察。结果4个月饲养期间内无肠梗阻发。3段肠浆肌膜腔内脾组织再生良好,组织结构与大网膜内移植脾组织无明显差别,2段再生较差,1段形成脓肿。结论肠浆肌膜腔内移植脾组织的量较大,可作为自体脾组织的移植术式。     

重症胆管炎23例临床治疗分析

目的：探讨急性重症胆管炎患者的手术时机和死亡原因。方法：回顾性分析23例急性重症胆管炎患者的治疗及预后情况。结果：死亡2例（手术死亡及传统治疗死亡各1例）。早期大剂量短期应用糖皮质激素患者休克得到纠正率85％，明显高于未用糖皮质激素患者休克纠正率50％。结论：急性重症胆管炎患者应在出现休克和（或）精神症状之前手术，对已出现休克的患者，应先给予充分的保守治疗，待病情稳定后再手术。贻误手术时机，严重合并症如多器官功能衰竭及高龄是死亡的主要原因。     

Central metabotropic glutamate receptors differentially participate in interleukin-1beta-induced mechanical allodynia in the orofacial area of conscious rats.

The present study investigated the role of central metabotropic glutamate receptors (mGluRs) in interleukin-1beta (IL-1beta)-induced mechanical allodynia and mirror-image mechanical allodynia in the orofacial area. Experiments were carried out on male Sprague-Dawley rats weighing 230 to 280 g. After administration of 0.01, 0.1, 1, or 10 pg of IL-1beta into a subcutaneous area of the vibrissa pad, we examined the withdrawal behavioral responses produced by 10 successive trials of an air-puff ramp pressure applied ipsilaterally or contralaterally to the IL-1beta injection site. Subcutaneous injection of IL-1beta produced mechanical allodynia and mirror-image mechanical allodynia in the orofacial area. Intracisternal administration of CPCCOEt, a mGluR1 antagonist, or MPEP, a mGluR5 antagonist, reduced IL-1beta-induced mechanical allodynia and mirror-image mechanical allodynia. Intracisternal administration of APDC, a group II mGluR agonist, or L-AP4, a group III mGluR agonist, reduced both IL-1beta-induced mechanical allodynia and mirror-image mechanical allodynia. The antiallodynic effect, induced by APDC or L-AP4, was blocked by intracisternal pretreatment with LY341495, a group II mGluR antagonist, or CPPG, a group III mGluR antagonist. These results suggest that groups I, II, and III mGluRs differentially modulated IL-1beta-induced mechanical allodynia, as well as mirror-image mechanical allodynia, in the orofacial area. PERSPECTIVE: Central group I mGluR antagonists and groups II and III mGluR agonists modulate IL-1beta-induced mechanical allodynia and mirror-image mechanical allodynia in the orofacial area. Therefore, the central application of group I mGluR antagonists or groups II and III mGluR agonists might be of therapeutic value in treating pain disorder.     

稳定性核素测定大鼠小肠蛋白质合成

目的：建立稳定性核素（[L-^15N]亮氨酸）测定大鼠小肠蛋白质合成率的方法。方法：分别测定静脉注射相同剂量[L-^15N]亮氨酸不同时相的大鼠小肠^15N丰度及不同剂量[L-^15N]亮氨酸同一时相的大鼠小肠^15N丰度。结果：大鼠小肠游离氨基酸池中^15N核素丰度在注射后0．5h内呈线性上升并达高峰，维持4h后缓慢下降，小肠蛋白质中的^15N丰度0．5h至12h基本维持不变；随着注射剂量的增加，大鼠小肠蛋白质分数合成率（FSR）亦增加，当[L-^15N]亮氨酸剂量在1．0mmol／kg以上，FSR并不随施加[L15N]亮氨酸剂量的加大而增加。结论：在进行大鼠小肠蛋白质合成率测定时，一次性静脉注射的测量最佳时限为0．5h，剂量为1．0mmol／kg。     

胰岛素强化治疗在2型糖尿病骨折患者围手术期的应用

Objective To investigate the best way to control the blood sugar level during the perioperation of bone fracture patients with type 2 diabetes(T2DM).Methods Bone fracture patients with T2DM were randomly divided into three groups:continuous subcutaneous insulin infusion group(insulin aspart,group CSII,n=20),glargine treatment group(insulin aspart+insulin glargine,group GA,n=20),and NPH treatment(insulin aspart+rh-insulin,group NA,n=20).The levels of fasting plasma glucose(FPG)and the 2 hours postprandial glucose(2h PG),blood glucose fluctuation(BGF),insulin dosage(ID),good effective time(GET),incidence of hypoglycemia,dawn phenomenon and infection,average time of stitches removal(ATSR),average hospitalized length(AHL)of three groups were compared.Results FPG and 2hPG,ID in group CSII[(6.32±1.18)mmol/L,(7.72±1.53)mmol/L,(35.40±1.60)IU]and group GA [(6.25±0.88)mmol/L,(7.32±1.17)mmol/L,(36.20±0.80)IU]were significantly lower than those of group NA [(7.44±1.36)mmol/L,(8.52±0.76)mmol/L,(40.50±2.40)IU,all P<0.05],simulaneously,BGF,GET incidence of complications,ATSR,AHL of group CSII and GA were significantly lower than those of group NA(all P<0.05).There were not significant difference between group CSII and group GA.Compared with group CSII,group GA had less costs in-hospital and better practicability.Conclusion Both CSII and insulin glargine combined with insulin aspart can effectively,safely,rapidly and stablely control hyperglycemia.and might be the first choice to control blood sugar for bone fracture patients with T2DM in perioperation.     

Acromioclavicular joint dislocation: a comparative biomechanical study of the palmaris-longus tendon graft reconstruction with other augmentative methods in cadaveric models

Background  

Acromioclavicular injuries are common in sports medicine. Surgical intervention is generally advocated for chronic instability of Rockwood grade III and more severe injuries. Various methods of coracoclavicular ligament reconstruction and augmentation have been described. The objective of this study is to compare the biomechanical properties of a novel palmaris-longus tendon reconstruction with those of the native AC+CC ligaments, the modified Weaver-Dunn reconstruction, the ACJ capsuloligamentous complex repair, screw and clavicle hook plate augmentation.
