普通外科手术患者伴发抑郁障碍的现况调查

目的：了解准备接受手术治疗的外科患者伴发抑郁障碍的情况,并分析其可能的影响因素。方法：运用ZUNG抑郁自评量表对104例手术患者伴发抑郁障碍的情况进行调查,依据患者的年龄、性别、文化程度、罹患疾病的性质、接受手术的规模大小等因素进行分组研究,应用SPSS10．0统计软件进行数据的统计学检验。结果：40．4％的普通外科手术患者合并有不同程度的抑郁障碍。其中伴发中、重度抑郁障碍者占14．42％;女性患者、大学或大学以上文化程度的患者、小学文化程度和文盲患者、罹患肿瘤性疾病的患者伴发抑郁障碍的比例较高;而手术规模大小、患者是否明确进一步治疗方案则不影响合并抑郁障碍的情况。结论：普通外科手术患者伴发抑郁障碍的比例较高,性别、文化程度、疾病性质是其主要影响因素。     

血管内皮细胞对增生性瘢痕成纤维细胞增殖的影响

目的：观察人脐静脉血管内皮细胞对增生性瘢痕成纤维细胞增殖活性的影响。方法：收集培养的人脐静脉血管内皮细胞上清条件培养液，加入培养的增生性瘢痕成纤维细胞之中，采用MTT法检测增生性瘢痕成纤维细胞增殖率，利用流式细胞仪分析细胞周期。结果：加入内皮细胞上清液的增生性瘢痕成纤维细胞增殖比对照组明显增加，且S期比例增高。结论：在瘢痕形成的过程中，内皮细胞被激活，激活的内皮细胞可能分泌某些活性物质，促进成纤维细胞增殖，刺激其进入细胞DNA合成期S期。

Very low wear of non-remelted highly cross-linked polyethylene cups: an RSA study lasting up to 6 years

Background and purpose Highly cross-linked polyethylenes (PEs) all appear to reduce wear dramatically in laboratory studies, although there is substantial variation in this respect between manufacturers. Nonremelted cross-linked PE is almost as tough as unirradiated PE, but is not completely stable and can oxidize in vivo, as has been shown in recent retrievals studies.

We had reported low wear and good clinical performance after 2 years for 10 non-remelted highly crosslinked PE cups compared to 16 conventional PE cups sterilized by gamma-in-air.

Method Because of possible degradation by free radicals, we followed up both cohorts for 5 years (conventional PE) and 6 years (highly cross-linked PE).

Result Mean (CI) proximal head penetration over the observation time was linear and measured 0.08 (0.02-0.13) mm for cross-linked PE and 0.42 (0.23-0.62) mm for conventional PE, and total penetration was 0.23 (0.1-0.35) mm and 0.75 (0.05-1.4) mm respectively. After subtracting creep, the annual wear for non-remelted highly cross-linked PE was below 6 µm. The cups had equally low migration and few radiolucencies.

Interpretation The theoretical possibility of oxidation in non-remelted highly cross-linked PE may not show clinically. However, it may be that cemented cups with their thicker PE are more forgiving than metal-backed cups with thin PE moving in the locking mechanism. So far, we can conclude that the Crossfire highly crosslinked polyethylene cups performed very well clinically, with extremely low wear even after almost 6 years. This is reassuring, but care should be taken in extrapolating these results to other cross-linked PEs or uncemented cups where toughness of PE is more of an issue.

One-stage surgical management for multilevel tuberculous spondylitis of the upper thoracic region by anterior decompression, strut autografting, posterior instrumentation, and fusion

STUDY DESIGN: A retrospective clinical study of 1-stage surgical management for multilevel tuberculous spondylitis of the upper thoracic region (MTSUTR). OBJECTIVE: MTSUTR has rarely been documented in the literature. We present a retrospective clinical study of 23 patients with MTSUTR treated by anterior decompression, strut autografting, posterior instrumentation, and fusion. The purpose was to determine the clinical efficacy of such surgical treatment for MTSUTR. SUMMARY OF BACKGROUND DATA: It is considered safe and effective to treat surgically tuberculous spondylitis with local spinal cord compression. Many reports have documented a good clinical efficacy of surgical management for spinal tuberculosis. However, how to deal with MTSUTR is rarely reported in the literature. METHODS: There were 14 men and 9 women, with average age of 35 years. All patients underwent 1 stage anterior debridement, strut autografting, and posterior instrumentation and received combined medication antituberculosis chemotherapy for 12 to 24 months (average 18 mo). The following data were followed up for an average period of 42 months (24 to 60 mo) in these patients: deformity angle, neurologic function, and spinal bony fusion. RESULTS: The average preoperative deformity angle was 44 degrees, correcting to 20-degree postoperatively and 24 degrees at final follow up. In the series, 19 patients with preoperative neurologic deficit restored by 1.3 grades according to Frankel. All patients got bony spinal fusion within 6 months postoperatively. There was no recurrent tuberculous infection. CONCLUSIONS: Single-stage anterior debridement, strut autografting, posterior instrumentation, and fusion proved safe and effective for MTSUTR, which can achieve goals of complete spinal cord decompression and good deformity correction.
