血清TBA评估慢性重型肝炎肝细胞损伤的临床价值

目的　进一步探讨血清总胆汁酸 (TBA)评估慢性重型肝炎患者肝细胞损伤程度及其预后的临床价值。方法　对慢性重型肝炎组 12 2例、慢性肝炎组 98例和正常对照组 4 8人同时测定TBA、总胆红素 (TBIL)及凝血酶原活动度 (PA) ,并分析它们之间的关系。结果　慢性重型肝炎患者血清TBA水平显著高于慢性肝炎组及正常对照组 (P <0 .0 1) ,TBA与TBIL呈正相关 ,与PA呈负相关 (分别为r =0 .712 ,P <0 .0 1;r =- 0 .832 ,P <0 .0 1) ;治愈 +好转组TBA明显低于恶化 +死亡组 (P <0 .0 1)。结论　慢性重型肝炎TBA显著升高 ,肝细胞损伤越严重 ,TBA水平越高。TBA是敏感的肝功能检测指标 ,对慢性重型肝炎的疗效及预后评估有一定的临床价值。     

Patello-femoral complications associated with total knee arthroplasty

The patello-femoral articulation accounts for a significant number of the complications that occur after total knee replacements and which require re-operation. These include problems with stability, component wear, fracture, loosening, and osteonecrosis. With careful attention to prosthetic design and surgical technique, these complications can be minimized.

阻塞性肺病呼气末肺残气量的CT评价

目的:探讨呼气末高分辨率CT(HRCT)对阻塞性肺病(OLD)患者的肺残气量的评估价值.方法:对有肺功能检测结果的13名健康志愿者与14例OLD患者行吸气与呼气末HRCT扫描,测量吸气与呼气状态下肺CT值,并目测呼气末HRCT扫描时肺残气量的范围.结果:所有的OLD与8名健康志愿者都有肺内空气残余,但OLD的范围明显增大.OLD患者在吸气与呼气时肺CT值变化及残气量分数与健康者明显不同,且与肺功能密切相关(P＜0.01).结论:呼气末HRCT可用于评估OLD患者肺残气量并可诊断这类疾病.肺CT值的测量与肺残气量的评估是两种有价值的分析方法.     

常见阴离子对血清氯离子选择性电极法测定的影响

目的:研究离子选择性电极在测定血清氯时的影响因素。方法:用E-555电解质分析仪测定氟化钠、溴化钠、碳酸氢钠、硫氰化钾、碘化钾、铁氰化钾、硫化钠以及叠氮钠溶液,并将溴化钠、硫氰化钾、碘化钾、铁氰化钾、硫化钠、叠氮钠分别加入Cl~-均值为100mmol/L的混合血清中观察其具体的干扰情况。结果:所测8种物质中氟化钠、碳酸氢钠的影响较小,而溴化钠、铁氰化钾、碘化钾、铁氰化钾、硫化钠、叠氮钠的影响较大。结论:溴离子、碘离子、硫离子、氢氰根离子、叠氮钠对离子选择性电极法影响性较大,我们在工作中应加以重视。     

Successful surgical treatment of secondary kwashiorkor after total gastrectomy: Report of a case

We report herein the case of a 56-year-old woman who developed secondary Kwashiorkor 9 years after undergoing a total gastrectomy for early gastric cancer. Until she began developing the symptoms of Kwashiorkor, including general fatigue, edema of the face and extremities, anemia, alopecia, and weight loss, she had been leading a normal life post-gastrectomy. Her symptoms were alleviated by total parenteral nutrition (TPN) therapy, but reappeared soon after TPN therapy was discontinued. Therefore, she required several subsequent courses of TPN. In an attempt to permanently resolve the ongoing Kwashiorkor symptoms, reconstructive surgery involving transposition of the jejunum from the previous Graham method to the interposition method was performed 10 years after the initial gastrectomy. After the second operation, her malnutrition was completely alleviated, and she has been in good health for the 8 years since. To our knowledge, there has been no other report of the symptoms of secondary Kwashiorkor after total gastrectomy being alleviated by altering the procedure of reconstruction of the intestinal tract. Thus, we recommend surgical treatment to alter the digestive continuity to a more physiological pathway for selected patients with secondary Kwashiorkor syndrome.     

ENTERAL VERSUS PARENTERAL NUTRITION AFTER OESOPHAGOGASTRIC SURGERY: A PROSPECTIVE RANDOMIZED COMPARISON

Background: There appears to be an emerging consensus that early postoperative nutritional support benefits the high-risk patient by decreasing septic morbidity, maintaining immunocompetence and improving wound healing. Enteral nutrition via a feeding jejunostomy has been associated with serious complications, with a reported mortality rate as high as 10%. while total parenteral nutrition has also been associated with a wide variety of complications. Methods: Ninety-seven patients undergoing oesophagectomy or gastrectomy underwent pre-operative nutritional assessment and were randomized to receive either total parenteral nutrition (47 patients) or enteral nutrition (50 patients). Results: There was no significant difference in the number of catheter-related complications between the two groups, but 9 (45%) patients in the total parenteral nutrition group had major morbidity (potentially fatal in two patients) requiring active intervention. Conclusions: This study demonstrates enteral nutrition to be safe and associated with mainly reversible minor complications. It is probable that immediate postoperative enteral feeding conserves the gut's integrity. Whether this leads to a reduction in postoperative septic complications has not been demonstrated by this study although there appears to be a trend in this direction, supporting the concept of enteral feeding as ‘primary therapy’. This can be safely, simply and economically achieved using a feeding jejunostomy placed at the time of surgery.
