目的 了解小儿烧伤的致伤因素和院前急救现状。方法 对十年来两家医院收治的小儿烧伤1403例按年龄、原因、场所以及院前急救进行回顾性分析。结果 小儿烧伤以0～3岁居多（占57．09％）；热液烫伤比例大（占70．28％）；家庭为烧伤主要场所（占78．12％）；院前急救失误普通存在，其中创面处理不当、未建立有效静脉通道和人为原因延误治疗比例较大。结论 小儿烧伤有一定规律，院前急救应加以重视。     

儿童颈椎间盘钙化症的影像诊断

目的 探讨儿童颈椎间盘钙化症的影像表现及诊断价值，并提高对本病的认识。方法 回顾分析16例儿童颈椎钙化性椎间盘病的影像表现。结果 16例患均行颈椎平片检查，5例行CT扫描并作了三维重建，8例行MRI检查。16例平片均显示了椎间盘钙化灶，均为单发，CT平扫加三维重建显示4例钙化呈卵圆形，1例钙化为不规则形。MRI检查不仅显示了椎间盘内改变还清晰显示了病变相邻椎体边缘信号改变，在T1、T2加权像上呈低信号。结论 平片检查可以显示椎间盘钙化；CT平扫加三维重建能清晰显示了钙化灶的大小、形态；MRI检查在显示受累椎体及周围组织的改变方面明显优于CT和平片。     

PGA指数和透明质酸在诊断慢性乙肝肝纤维化中的价值

目的：寻找一种简便实用的诊断慢性乙型肝炎纤维化的方法。方法：以78例经肝穿刺病理证实的慢性乙型肝炎为对象，测定并比较了由PT、GGT、ApoA1组成的PGA指数和HA、LN、PⅢP、C－IV与肝内纤维化程度(S)和炎症活动度（G）的关系。结果：（1）LN、PⅢP、C－IV在轻度慢性乙肝时无明显升高，在中度慢性乙肝时明显高于正常，但与轻度慢性乙肝无差异，而PGA指数和HA不仅在轻度慢性乙肝时显著升高，而且在轻中度间差异明显.因重度慢性乙肝和活动性肝硬化时，五项指标均显著增高。（2）在G2－4期，HA、LN、PⅢP、C－IV均明显高升，但在G1期，只有PGA指数高于正常，且各期间差异显著。（3）在S1－2期，只有PGA指数、HA、C－IV明显上升，但C－IV的上升幅度远低于PGA指数和HA。（4）加以PGA＞4．5或HA＞200μg／L作为判断临界值，则两者判断肝纤维化的敏感性均＞94％，精确性＞91％，特异性＞86％，如两者结合，则分别达到98．3％、95．2％和96．4％。结论：PGA指数和HA均是反映慢性乙型肝炎患者肝内纤维化程度的良好指标，两者联合检测则可达到最大的价值效益比。

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.

Lipid extract from completely sporoderm‐broken germinating Ganoderma sinensis spores elicits potent antitumor immune responses in human macrophages

Ganoderma sinensis has been used widely in Oriental countries for the prevention and treatment of various diseases including cancer. Previous studies have shown that the lipid extract from Ganoderma exhibits direct cytotoxicity against tumor cells. Here, it is reported that the lipid extract from germinating G. sinensis spores, at lower concentrations that have no direct tumoricidal activity, induce potent antitumor immune responses in human monocytes/macrophages. Upon stimulation with the lipid extract, monocytes/macrophages exhibited markedly increased production of proinflammatory cytokines and surface expression of costimulatory molecules. Conditioned medium from stimulated cells effectively suppressed the growth of tumor cells. Apparently, the lipid extract triggered macrophage activation via a mechanism different from that associated with LPS. Moreover, it was observed that the lipid extract could partially re‐establish the antitumor activity of the immunosuppressive tumor‐associated macrophages. These results indicated that in addition to its direct tumoricidal activity, the lipid extract from G. sinensis spores could exert antitumor activity by stimulating the activation of human monocytes/macrophages.
