Association between age and clinical characteristics of renal cell carcinoma in adult patients

AIM: To study the association between age and clinical characteristics of renal cell carcinoma in adult patients. METHODS: Three hundred and ten patients with renal cell carcinoma were classified into three groups: or=60 years group. The clinical characteristics of the three groups were compared to define the association. RESULTS: The male/female ratio was 1.3/1, 2.0/1, 3.3/1 in the three groups, respectively, and a significant difference appeared when comparing the or=60 years group (P=0.010). The respective percentage of incidental renal cell carcinoma was 27.9%, 43.2%, 31.2%, and it was significantly higher in the 41-59 years group than the >or=60 years group (P=0.047). The incidence of poorly differentiated renal cell carcinoma decreased with age increasing (11.6% vs 5.2% vs 2.7%), and there was significant difference between the or=60 years group (P=0.038).

复方胰岛素凝胶剂促进大鼠皮肤溃疡愈合的初步研究

目的:研究复方胰岛素凝胶剂对大鼠皮肤溃疡的促愈合作用,并探讨其可能的作用机制。方法:18只Wistar大鼠背部各制备4个皮肤溃疡模型,共复制溃疡72个,随机将溃疡分为复方胰岛素凝胶治疗组(A组)、凝胶基质对照组(B组)、空白对照组(C组)。以治疗后不同时间点各组溃疡面积、溃疡愈合速度及组织病理学检查评价修复效果。结果:在伤后头10天内,A组溃疡缩小最明显,愈合速度明显快于B组、C组。伤后14天,A组溃疡基本愈合,皮肤结构完整、上皮化较厚;而B、C组溃疡仍未完全愈合,皮肤结构不完整、上皮化较薄。结论:局部应用复方胰岛素凝胶剂对大鼠皮肤溃疡有促愈合作用。     

多层螺旋CTA:不同重建方法在主动脉瘤腔内隔绝术后的应用评价

目的：探讨多层螺旋CT血管造影不同重建方法在主动脉瘤腔内隔绝术后的临床应用价值。材料与方法：46例主动脉瘤腔内隔绝术后行多层螺旋CT血管造影，采用准直2.5mm，层厚3.0mm，螺距为6，重建方法为容积显示技术（volume rendering，VR）、表面阴影遮盖显示(shade surface display，SSD)及最大密度投影法（maximum intensity projection，MIP），并对三种方法进行比较。结果：46例中有1例术后内支架出现局限性断裂，VR及MIP均清晰显示了内支架的变化，SSD未能显示。1例内支架展开不良，三种重建方法均明确显示；6例术后出现渗漏，VR清晰显示渗漏的部位、形态及内漏量，MIP、SSD仅显示其中的5例，三者中以VR显示最佳。在显示支架内血流情况及瘤周血栓方面，VR能明确支架内有无血栓形成及腔内隔绝术后的转归变化，VR显示1例术后支架内血栓形成SSD及MIP未能显示。结论：多层螺旋CT能在较短时间内进行大范围的扫描，有利于主动脉病变的检查；VR图像优于SSD及MIP，能为术后内支架情况提供更多更准确的信息，VR技术应作为主动脉瘤内支架术后的首选三维重建方法。     

心理干预对错[牙合]畸形治疗中合作行为及结果的影响

目的：观察心理干预对错[牙合]畸形患者正畸治疗中合作行为及结果的影响。方法：对门诊口腔科60例青少年[牙合]畸形患者随机分为干预组和对照组各30例。两组均由从事正畸工作5年以上的主治医师采用标准方丝弓技术进行矫正治疗，干预组同时实施心理干预等心理治疗。将两组治疗中的合作行为和结果进行比较分析。结果：心理干预组自律性、主动性、自觉性、矫治时间、满意度等均明显优于对照组，差异有显著性（P〈0．01）。结论：心理干预对青少年正畸患者治疗中合作行为和结果有明显影响，通过心理干预能提高矫治的效果，保证治疗的顺利完成。     

Diet and premenopausal bilateral breast cancer: A case-control study

We investigated associations between diet and premenopausal bilateral breast cancer in a familial matched case-control study. We studied 140 cases from population-based registries in Los Angeles County (California) and Connecticut, and from the major hospitals in the southern parts of the Province of Quebec. Unaffected sisters of the cases served as matched controls (222 total). Dietary intake were assessed with a food frequency questionnaire. Total fat, monounsaturated fat, polyunsaturated fat, oleic acid, and linoleic acid intake was inversely associated with premenopausal bilateral breast cancer risk. Consumption of carbohydrates (and sweetened beverages) was associated with an increased risk. We observed no associations for dietary fiber, antioxidants, or major food groupings, but we did observe inverse associations for intake of low fat dairy products and tofu. These findings suggest that monounsaturated and polyunsaturated fats, as well as soy foods, might reduce the risk of premenopausal bilateral breast cancer.     

Mifepristone-induced abortion and birth weight in the first subsequent pregnancy.

OBJECTIVES: To assess the effect of a medically induced abortion (MA) on birth weight in the first subsequent pregnancy. METHODS: Pregnant women who had had a MA, a surgical abortion (SA), or primigravidas with no history of abortion (NA), were recruited for a prospective cohort study between July 1998 and February 2001. The sample for the present analysis included 12995 singleton live births at term. RESULTS: The overall incidence rate of low birth weight (LBW) was 1.0%. The rates of LBW in the MA, SA, and NA groups were 1.0%, 0.9%, and 1.2, respectively. There were no significant differences in LBW rates between the MA and SA groups, neither between the MA and NA. Logistic regression analysis was used to estimate the effects of MA on birth weight, and we found no relationship between risk of LBW and MA. CONCLUSIONS: We did not find a statistically significant relationship between a history of one medically induced abortion and LBW for the first subsequent term pregnancy.
