早期肠内复方谷氨酰胺在重症急性胰腺炎治疗中的应用疗效

目的:分析早期肠内复方谷氨酰胺在重症胰腺炎(severe acute pancreatitis,SAP)治疗中的应用疗效.方法:选取2012-01/2014-01青海红十字医院接收治疗的108例S A P患者.采用随机数表法将108例患者分为观察组和对照组,各54例.给予对照组患者早期肠内营养,给予观察组患者谷氨酰胺联合早期肠内营养.对比两组治疗后的疗效、肝肾功能和急性生理与慢性健康状况Ⅱ(acute physiology and chronic health evaluationⅡ,APACHEⅡ)评分,并比较两组患者治疗前后血清肿瘤坏死因子α(tumor necrosis factoral pha,TN F-α)、C反应蛋白(highsensitivity C-reactive protein,hs-CRP)、白介素1B(interleukin 1B,IL-1B)、IL-8、IL-6的水平.结果:治疗前两组患者的APACHEⅡ评分、谷丙转氨酶(alanine transaminase,ALT)、血尿素氮(blood urea nitrogen,BUN)、总胆红素(total bilirubin,TBIL)、谷草转氨酶(aspartate transaminase,AST)和Scr均高于治疗后,治疗后观察组患者的APACHEⅡ评分、ALT、BUN、TBIL、AST和Scr较对照组患者较低,比较两组间差异统计学具有意义(P0.05).治疗后两组患者的血清TNF-α、hs-CRP、IL-1B、IL-8、IL-6的水平与治疗前比较下降,IL-10升高,比较两组间差异统计学具有意义(P0.05).治疗后观察组患者的血清TNF-α、hs-CRP、IL-1B、IL-8、IL-6的水平均低于对照组患者,IL-10高于对照组患者,比较两组间差异统计学具有意义(P0.05).结论:早期肠内复方谷氨酰胺能够显著改善SAP患者的全身炎症状态,具有较好的临床疗效,可以在临床上进一步推广和使用.     

Off pump coronary artery bypass (OPCAB) in critical left mainstem stenosis—Our experience

Background Beating heart surgery has now become the commonest technique of doing Coronary Artery Bypass Graft Surgery (CABG) in our country. It is being used even in such high risk situations like diffuse coronary disease and Critical Left Main stem Stenosis (LMCS) with good results. The aim of this study is to retrospectively review our results in Off-Pump Coronary Artery Bypass Surgery (OPCAB) in patients with critical left main stem stenosis. Methods This study is a retrospective analysis of the data of patients who underwent primary coronary artery bypass surgery. During the period from April 2003 to September 2005 a total of 64 patients underwent OPCAB procedure for critical LMCS. During the same period 10 patients underwent CABG on Cardio Pulmonary Bypass (CPB). The age range was 36–77yrs. The sex distribution was M: F 53∶10. Ten patients were done as emergency. 2 of them were on Intra Aortic Balloon Pump (IABP) support preoperatively. 10 patients were high risk with a Euro score of ≥5. Results Left Internal Mammary Artery (LIMA) was used in 78% of cases. Average grafts per patient was 2.96. The median ventilation time was 5.91 hrs. New IABP insertion in postoperative period was required in 1 patient. One patient was reexplored for bleeding. There was one perioperative myocardial infarction. 57% of patients did not need any blood transfusion. There was no conversion to CPB. There was no operative mortality. Inotropes were used in ten cases. Conclusions OPCAB is a safe method of revascularization in patients with critical LMCS. Preoperative IABP is useful in patients with cardiogenic shock. However, there is a place for CPB in patients needing additional procedures like Mitral Valve repair (MV repair) or Dor's procedure or when the vessels are very diffusely diseased. Those patients who are unstable despite IABP support may be managed by Beating heart On Pump (BHOP) technique.     

氟西汀与阿米替林治疗105例抑郁障碍病人的双盲对照试验

目的：评价国产氟西汀的抗抑郁作用及安全性。方法：采用随机、双盲对照、多中心研究，分为国产氟西汀组５７例（男性２２例，女性３５例；年龄４０±ｓ１３ａ），口服氟西汀２０ｍｇ，ｑｄ，阿米替林５７例（男性２７例，女性３０例；年龄４０±１４ａ），口服阿米替林７５ｍｇ，ｂｉｄ，疗程６ｗｋ。结果：氟西汀治疗抑郁障碍的疗效与阿米替林相当，总有效率分别为８５％及９２％（Ｐ＞０．０５）；氟西汀组的主要副作用有口干、便秘、恶心、心动过速等，但较之阿米替林程度轻且发生率低。结论：氟西汀的抗抑郁作用与阿米替林相当，副作用少，服用方便。     

Challenges in accessing multidisciplinary pain treatment facilities in Canada

PURPOSE: The objective of this survey was to examine the services offered by multidisciplinary pain treatment facilities (MPTFs) across Canada and to compare access to care at these MPTFs. METHODS: A MPTF was defined as a clinic that advertised specialized multidisciplinary services for the diagnosis and management of patients with chronic pain, having a minimum of three different health care disciplines (including at least one medical speciality) available and integrated within the facility. The search method included approaching all hospital and rehabilitation centre administrators in Canada, the Insurance Bureau of Canada, the Workplace Safety and Insurance Board or similar body in each province. Designated investigators were responsible for confirming and supplementing MPTFs from the preliminary list for each province. Administrative leads at each eligible MPTF were asked to complete a detailed questionnaire regarding their MPTF infrastructure, clinical, research, teaching and administrative activities. RESULTS: Completed survey forms were received from 102 MPTFs (response rate 85%) with 80% concentrated in major cities, and none in Prince Edward Island and the Territories. The MPTFs offer a wide variety of treatments including non-pharmacological modalities such as interventional, physical and psychological therapy. The median wait time for a first appointment in public MPTFs is six months, which is approximately 12 times longer than non-public MPTFs. Eighteen pain fellowship programs exist in Canadian MPTFs and 64% engage in some form of research activities CONCLUSION: Canadian MPTFs are unable to meet clinical demands of patients suffering from chronic pain, both in terms of regional accessibility and reasonable wait time for patients' first appointment.     

原发性肉碱缺乏致脂质沉积性肌病的临床与病理特点

目的 分析原发性肉碱缺乏致脂质沉积性肌病（LSM）的临床与病理特点。方法 回顾性分析4例可能LSM患者的临床资料。结果 本组患者为亚急性或慢性起病，主要表现为近端肌无力，疲劳不能耐受；血清肌酶有不同程度的升高；肌电图示肌源性损害；病理检查示肌纤维内可见大量细小空泡和裂隙形成；MGT染色无破碎红纤维，油红O染色显示空泡为大量脂滴充填；受累纤维以Ⅰ型纤维为主。电镜证实肌纤维内脂滴堆积，可伴有线粒体的轻度增多。改善能量和糖皮质激素治疗有效。结论原发性肉碱缺乏致LSM是一种以易疲劳和肌无力为主要临床表现的脂质代谢障碍性肌病，病理改变以肌纤维内脂滴堆积为主，一般不伴有线粒体结构的明显异常。糖皮质激素治疗可获得良好疗效。
