骨样骨瘤诊断与治疗

目的：为了进一步了解骨样骨瘤的临床特点。方法：对１０例骨样骨瘤患者的诊断与治疗进行回顾分析。结果：１０例患者均行手术治疗并经病理证实为骨样骨瘤,术后经１～１０ａ随诊效果良好。结论：无论是骨干骨样骨瘤还是椎体骨样骨瘤,普通Ｘ光片往往不能显示出典型的瘤巢,ＣＴ、ＭＲＩ及同位素扫描方能显示出瘤巢,瘤巢所在的部位往往是反应骨最为隆起的部位,瘤巢的准确定位及彻底切除是获得良好效果的关键,术中在切除标本内找到

原发性小肠恶性肿瘤的诊治

目的探讨原发性小肠恶性肿瘤临床表现的共同规律和有效的诊断方法及治疗措施,以利早期诊断与提高疗效。方法对７５例原发性小肠恶性肿瘤进行分析,生存率计算用寿命表法,生存分析用ＣＯＸ模型。结果１３例做Ｘ线胃肠钡餐检查,诊断准确率达８４．６％。根治性切除术后１,３,５年生存率分别为８７．５％、６８．７％和４８．１％,姑息性切除术后１,３,５年生存率分别为５７．９％、３３．８％和２４．１％。用ＣＯＸ模型对各临床因素进行预后分析,选入模型的因素有年龄、组织学类型、肿瘤部位和手术方式。结论Ｘ线胃肠钡餐检查是最有价值的诊断方法。根治性手术切除是最有效的治疗手段。影响原发性小肠恶性肿瘤预后的因素有年龄、组织学类型、肿瘤部位和手术方式,而化学治疗意义不大。     

Changes of nitric oxide synthase activity and free methylarginines contents in regenerating rat liver after partial hepatectomy

In the present study, liver regeneration rate (%) was increased up to 70% 3 days after partial hepatectomy (PH). Nitric oxide synthase (NOS) activity in liver tissue as well as serum nitrite/nitrate content had no timed response, revealing no significant difference between shamoperated and partially hepatectomized rat liver. Contents of free methylarginines in liver tissue were increased biphasically in a time-dependent manner after PH. However, those in serum did not exhibit the same patterns as in liver. Taken together, the results suggest that N^G-monomethyl-L-arginine (MMA) and N^G, N^G-dimethylarginine (DMA) play a role in inhibiting nitric oxide (NO) synthesis in regenerating rat liver because the increase of their contents was synchronized with NOS expression.     

Constituents of the herb ofIsodon excisus var.coreanus

The studies were carried out to evaluate the constituents in the aerial part ofIsodon excisus var.coreanus (Labiatae). From the aqueous fraction of methanol extract, compound 1 (alpha-[[3-(3, 4-dihydroxyphenyl)-1-oxo-2-propenyl]oxy]-3,4-dihydroxy-benzenepropanoic acid), compound II (9-methyl-dihydroferulic acid-4-O-beta-D-glucopyranosyl (1-->2)-alpha-L- rhamnopyranosyl (1-->4)-beta-D-glucopyranoside), compound III (ent-7alpha, 11alpha, 15beta-trihydroxy-kaur-16-en-1-O-beta-D-glucopyranoside) and compound IV (2alpha, 3beta, 7alpha, 23-tetrahydroxy-olean-12-en-28-oic acid 28-O-beta-D-glucopyranoside) were isolated and identified on the basis of their physicochemical and spectroscopic evidences[IR, FAB(-)MS,(1)H-NMR,(13)C-NMR, HMQC,(1)H-(1)H COSY and HMBC (Heteronuclear Multiple Bond Connectivity)]. Especially, New compounds II and III were named isodonin A and Isodonin B respectively.     

从粤东丰溪自然保护区白腹巨鼠和褐家鼠体内分离出莱姆病螺旋体

大理地区正常人血清TT_3、TT_4水平

对比大理地区健康汉族人与白族人血清总三碘甲状腺原氨酸（ＴＴ３）、总甲状腺素（ＴＴ４）含量,建立本地区健康人ＴＴ３、ＴＴ４正常参考值。方法：对１００７例健康人（汉族６９１例,白族３１６例）进行血清ＴＴ３、ＴＴ４、ＲＩＡ检测。结果：健康汉族人与白族人血清ＴＴ３、ＴＴ４测定值相近,经统计学处理无显著性差异（Ｐ＞００５）;６０～７５岁年龄组的健康老年人血清ＴＴ３、ＴＴ４含量比其他年龄组明显降低（Ｐ＜００１）。结论：经检测得出的各年龄ＴＴ３、ＴＴ４水平,不论白族或汉族,男性或女性,均可作为正常参考值;６０岁以上健康老人ＴＴ３、ＴＴ４含量低于其他年龄是老年人正常的生理变化。
