On the Role of Proteasomes in Cell Biology and Proteasome Inhibition as a Novel Frontier in the Development of Immunosuppressants

The proteasome, a large protease complex in cells, is the major machinery for protein degradation. It was previously considered a humble garbage collector, performing housekeeping duties to remove misfolded or spent proteins. Until recently, the interests of immunologists in proteasomes were focused largely on its role in antigen processing. Its real importance in cell biology has only been revealed contemporarily due to the availability of relatively specific inhibitors. It has now become increasingly clear that many aspects of immune responses highly depend on proper proteasome activity. Recently, a proteasome inhibitor has been successfully used to prevent acute as well as ongoing heart allograft rejection in mice. Such inhibitors are also efficacious in treating several autoimmune diseases, such as arthritis, psoriasis, and probably type I diabetes, in animal models. Phase II and III clinical trials of proteasome inhibitors in treating various tumors have shown promising results, and the side-effects of these drugs are tolerable. Therefore, proteasome inhibition represents a new and promising frontier in immunosuppressant development.     

218例乳腺癌术后十年随访观察

对218例女性乳癌术后进行了十年以上的随访观察。随访率为95.87％。术后总的十年生存率为54.87％。Ⅰ期为85.71％,Ⅱ期为53.09％。Ⅲ期为30.76％。阐明了术后疗效与妊娠哺乳,肿瘤部位,肿瘤大小,临床期别,淋巴结转移情况及病理类型有明显关系。讨论了手术方式对术后的影响,提示扩大根治术对Ⅰ、Ⅱ期乳癌并无明显优越性。     

保留肾单位手术治疗早期小肾癌21例临床分析

OBJECTIVE: To evaluate the clinical effects of nephron-sparing surgery in patients with early-stage small renal cell carcinoma. METHODS: Nephron-sparing surgery was performed in 21 patients with renal cell carcinoma including 1 with solitary kidney, 3 with unilateral tumor and contralateral renal compromise, and 17 with unilateral tumor and normal contralateral kidney. The diameter of the tumors ranged from 1.5 to 6.0 cm, with a mean of 2.8 cm. The tumor diameter in 17 patients with normal contralateral kidney was less than 4 cm (mean 2.5 cm) and the average diameter in 4 patients with contralateral renal compromise was 4.2 cm. Sixteen cases were in stage T(1), 4 in stage T(2), and 1 in stage T(3). Of the 21 patients, 4 underwent tumor enucleation, 10 polar nephrectomy and 7 wedge resection. RESULTS: All patients were followed up for an average of 40.8 months (7 to 66 months). One patient suffered a right lung and mediastinum metastasis 3 years after the surgery later and 1 with chronic glomerulonephritis required dialysis 27 months after the operation. No surgical complication or local recurrence were found in other patients. CONCLUSION: As a safe and effective therapy for early-stage small renal cell carcinoma, nephron-sparing surgery can be considered as the gold-standard therapy for patients with lesions less than 4 cm in T(1) and T(2) stages of localized unilateral tumor with normal contralateral kidney.     

下腹部Joel—Cohen切口术后切口愈合临床观察

目的探讨肥胖患者下腹部手术采用Joel—Cohen切口对预防非感染性切口裂开的临床效果。方法选择切口部位皮下脂肪层厚达4—5cm的妇产科手术患者90例，随机分为观察组44例，采用Joel—Cohen切口；对照组46例，采用下腹正中直切口。观察切口愈合和脂肪液化情况。结果观察组切口甲级愈合率显著高于对照组（P〈0．01）；脂肪液化切口裂开率显著低于对照组（P〈0．05）。结论脂肪组织厚达4—5cm以上下腹部手术切口，采用Joel—Cohen切口可以减少脂肪液化，切口愈合显著优于下腹直切口，值得临床推广应用。

外伤性延迟性脾破裂的诊断和治疗（附21例报告）

目的探讨外伤性延迟性脾破裂的发病规律、临床特点、诊断和治疗方法。方法结合国内外资料及本组病例进行回顾性分析。结果明确诊断16例，误诊为肝破裂2例，宫外孕破裂2例，脾肿瘤1例。21例均手术治疗，行脾切除14例，其中保留副脾2例；脾切除加自体脾组织网膜内移植术3例；脾缝合修补术3例；脾部分切除术1例。死亡1例，原因有就诊晚、失血性休克。结论本病由于腹腔内出血与受伤时间间隔长，容易误诊。诊断除依靠病史、临床表现外，应及时进行腹腔穿刺、B超及CT检查。治疗以脾切除为主，可根据病情、脾破裂的程度以及是否有合并伤等情况采取保脾手术。
