[目的]研究膝以下严重开放性创伤的修复。[方法]自1995年3月～2005年3月收治膝以下严重开放性损伤153例，Ⅰ期修复106例，Ⅱ期修复47例，7种内固定方法，11种皮瓣修复方法。[结果]153例中随访132例，时间6个月～5年，平均17个月，术后功能优良率85．7％，皮瓣成活率良好。皮瓣局部坏死25例，骨不连4例，慢性感染8例，骨髓炎3例。[结论]改进的腓肠神经营养血管皮瓣和皮瓣桥手术扩大了皮瓣的应用范围，减少了并发症的发生。本研究为膝以下严重开放性损伤的修复提供了良好的方法；熟练的显微外科技术和各种组织瓣的合理应用是修复成功的关键。     

健康信念模式在分娩中的应用探讨

目的探讨增强产妇健康信念对产妇分娩方式及产后康复的影响，提高产妇康复质量及产科工作质量。方法将300例产妇随机分为观察组和对照组，对观察组产妇进行分娩相关知识强化培训，增强产妇自然分娩及自我护理信念．对照组只进行一般入院宣教，比较两组剖宫产率、纯母乳喂养、产后24小时自护率等指标。结果观察组产妇剖宫产率明显低于对照组，而纯母乳喂齐、产后24小时自护率等指标均高于对照组。结论增强产妇健康信念，能帮助其自然分娩，降低剖宫产率，提高产妇康复质量。     

Cementless total hip arthroplasty in the treatment of severe hip dysplasia or dislocated hips

We present our experience over 6 years with the use of uncemented total hip arthroplasty (THA) for developmental dysplasia of the hip (DDH) with a mean follow-up of 3 years. In a 6-year period, 26 THAs were performed in 19 patients with Hartofilakidis grades 2 and 3 dislocation of the hips. Out of 19 patients, seven had bilateral dislocations. Uncemented acetabular and femoral components were used in all patients. Patients with a minimum follow-up of 1 year were included in the study. The average age at the time of surgery was 38 (range 20–69) years. Approaches used include trochanteric osteotomy in 14 (54%) patients and a lateral approach in 12 (46%) patients. In addition, subtrochanteric osteotomy was performed in four (15%) patients. A Mallory-head femoral stem was used in 15 (58%) patients; a DDH femoral stem was in nine (35%), and the S-ROM femoral prosthesis in two (8%). A Mallory head acetabular shell was used in all cases, a 22.2-mm chrome cobalt head was used in 18 (69%), and a 28-mm chrome cobalt head was used in eight (31%). The average follow-up was 3 (range 1–6) years. The Harris hip score (HHS) improved in the cohort from a mean preoperative score of 51 to a mean postoperative score of 86 (p<0.05). The mean preoperative SF36v2 score was 42 compared to postoperatively of 67(p<0.05). The complication rate was 11% with nonunion of a subtrochanteric osteotomy in one patient, dislocation in one, and trochanteric bursitis due to fracture of Dall-Miles cables in one. THA for DDH is a technically demanding procedure. This short-term follow-up of THA for DDH using uncemented implants is encouraging for arthrosis secondary to DDH. It provides better function compared to arthrodesis or excision arthroplasty, especially in young individuals. A long-term follow-up is required in order to establish the role of this management strategy.     

隐性失血对双侧人工全膝关节同期置换手术的影响

[目的]研究双侧人工全膝关节同期置换术术后隐性失血的相关因素。[方法]对2005年2月～2007年2月44例双侧人工全膝关节同期置换术患者进行回顾性分析，通过Gross方程，根据身高、体重及手术前后的红细胞压积推算术后平均显性失血量及平均隐性失血量。[结果]平均总失血量2065ml，其中显性失血量1198ml，隐性失血量867ml，使用自体血回输患者总失血量为2180ml，隐性失血量为937ml（42％）；未使用自体血回输患者的总失血量是1950ml，隐性失血量是799ml（41％）；两组的隐性失血相比差异无统计学意义。[结论]双侧人工全膝关节同期置换术术后隐性失血量占总失血量的比例较高，且使用自体血回输不能完全满足机体恢复体循环的需要，在围手术期要特别注意及时补充血容量。     

Arthroscopic irrigation - a cautionary tale

A fit 38-year-old female patient developed absent foot pulses following a routine arthroscopic partial medial meniscectomy. Irrigation fluid, which was delivered using an arthroscopic flushing set, had extravasated through a ruptured Baker's cyst into the popliteal fossa causing vascular compression and spasm. The pulses gradually returned to normal following the procedure. Knee arthroscopy is a common procedure and a Baker's cyst is a common sequel to degenerative disease. With the increasing popularity of pressurised fluid irrigation systems, this previously unreported complication is both relevant and important.     

血清LSA测定在恶性肿瘤临床诊断中的初步应用

本文根据Svennerholm和蒋谷人等的方法略加改良,测定了蚌埠地区113例正常人,71例恶性肿瘤患者和82例非肿瘤疾病患者血清脂质结合唾液酸(LSA)的含量。正常值为12.4mg/dl(SD=±3.6mg/dl),71例不同肿瘤患者的平均值为28.2mg/dl(SD=±9.7mg/dl),阳性率为88.7％,82例非肿瘤疾病患者的平均值为16.82mg/dl(SD=±5.4mg/dl),假阳性率为17％。方法的灵敏度,重复性(平均CV=3.6％)和回收率(平均回收率=101.4％)测定结果是满意的。本研究的初步结果表明,血清LSA测定对肺癌、白血病、胃癌和食管癌具有一定的临床诊断价值。     

Aggressive resection for advanced pancreatic carcinoma

An aggressive pancreatectomy was performed on a 53 year old Japanese man with advanced cancer of the pancreas. The tumor originated from the body of the pancreas and invaded the stomach, duodenum, left kidney, transverse colon and common hepatic artery. An unexpected cancer was also found in the head of the pancreas during the operation. Therefore, total pancreatectomy, total gastrectomy, left adrenonephrectomy, resection of the left transverse colon and dissection of the regional lymph nodes were performed. Resection of the common hepatic artery was also performed, followed by an end-to-end anastomosis between the common hepatic artery and celiac trunk. The postoperative course was uneventful and the patient was doing well until nine months after the operation when multiple metastatic lesions were noted in the liver. He died 391 days after the operation from hepatic failure.     

25种常用食物总脂质、总磷脂和主要磷脂含量的比较

<正> 磷脂是构成生物细胞膜的基本组分,以其规律的结构保证细胞的正常形态和功能。因而经常有一定质量的磷脂保证,是维持所有细胞健康生长和生理功能的基础。磷脂已被广泛应用为食品添加剂,由于磷脂是一种天然产物,更加适应当今世界对“非化学添加物”的需要。但目前的食物成分表均无磷脂的含量,为此对云南、陕西、辽宁等地常用食物中总脂质、总磷脂和主要磷脂的含量进行了分析。     

Clinical and radiological profile of symptomatic knee osteoarthritis in Malaysia

Aims: To create a clinical and radiological profile of patients with symptomatic osteoarthritis of the knee in Malaysia. Methods: One hundred consecutive patients presenting with symptomatic knee osteoarthritis at a private rheumatology clinic were profiled for demographic and clinical features. Anteroposterior weight‐bearing, skyline and lateral knee X‐rays were taken. Statistical Package for Social Sciences was used for data analysis. Results: Women predominated (93%). Fifty‐eight percent of the patients reported bilateral knee pain. Difficulty in walking, climbing and squatting was high (85%, 97% and 93% respectively). Patients with knee pain had a higher BMI than controls. Radiological abnormality, related to osteoarthritis was present in 97%. Osteophytes were generally tricompartmental while joint space narrowing was less evident in the lateral tibiofemoral joint than in the medial tibiofemoral joint and the patellofemoral joint. Almost half (49%) the patients manifested radiological varus deformity The severity of radiological abnormality increased with age. Although patients with unilateral pain had milder radiological abnormality, it tended to be bilateral. Clinically detectable hip abnormality and nodal osteoarthritis were uncommon, as was radiological chondrocalcinosis. Conclusions: Patients presenting with symptomatic knee osteoarthritis to a rheumatology service had a high degree of disability, radiological abnormality and varus deformity. Radiological abnormalities were essentially bilateral and tricompartmental.
