毫安增大照片密度下降的原因

X线照片上的影像是被照肢体各种组织结构的平面投影,是各种组织的密度及厚度对吸收X线量差异的显示。满意的X线照片应具有适当的密度,充分的显示出肢体内部结构层次和鲜明地分清各层次之间的密度差异,才能使照片获得良好的清晰度和对比度,达到X线诊断的目的。     

光子嫩肤技术在治疗烧伤患者皮肤血管扩张中的应用

强脉冲光子(IPLTM)技术是一种针对各种损容性皮肤病变,如色素性病变、血管性病变、皮肤光损害等的非剥脱性的光学治疗技术,主要通过多种波长的强光选择性地损伤扩张的毛细血管内的血红蛋白,形成微血栓而达到治疗血管扩张目的[1]。面部深Ⅱ度及Ⅲ度烧伤的创面愈合后,往往出现不同程度的血管扩张。而血管扩张不仅会影响患者的容貌,而且血管的数量与瘢痕形成密切相关[2]。2003年10月~2005年6月,我们对面部深Ⅱ度及Ⅲ度烧伤创面愈合后血管扩张明显的患者进行强脉冲光子治疗,经过1个疗程的治疗及治疗后的随访观察,效果满意,报告如下。1资料与方…     

支气管哮喘患儿的血铅水平分析

目的 研究支气管哮喘患儿的血铅水平,探讨儿童铅中毒与支气管哮喘的关系.方法 对56例支气管哮喘患儿(哮喘组)及40例同龄健康儿童(对照组)采用石墨炉原子吸收光谱法进行血铅水平测定.结果 哮喘组的血铅水平为(0.593±0.200) μmol/L,明显高于对照组的(0.476±0.193)μ mol/L,P<0.05;哮喘组的铅中毒率为53.6%,亦明显高于对照组的30.0%,P<0.05.哮喘严重程度与血铅水平呈正相关,r=0.286,P<0.05.结论 儿童支气管哮喘存在着血铅水平增高,血铅水平增高与儿童支气管哮喘有一定关系,防治儿童支气管哮喘应关注患儿血铅水平.

强化精氨酸肠内营养对烧伤患者营养状况和细胞免疫的影响

Objective To investigate the effects of arginine enriched enteral nutrition (EN) on nu-tritional status and cellular immunity of severely burned patients. Methods Randomized, single blind, parallel and positive control investigation was employed in the study. Thirty severely burned patients were di-vided into enteral immune nutrition (EIN) group and EN group. Sixteen patients in EIN group received en-teral nutrition enriched with arginine, while the other 14 patients in EN group received standard enteral nu-trition. Nutritional support was continued for 14 days. Gastrointestinal reaction of patients in 2 groups was observed. Fasting venous blood was drawn from patients of both groups before receiving nutrition treatment and on the morning of 7th, 14th day of treatment. Level of serum protein, hepatic function parameters, renal function parameters, fasting-blood glucose, and subpopulations of T lymphocytes in peripheral blood were determined. Results (1) Incidence of gastrointestinal side effect in EIN group (25.0%) was close to that of EN group (21.4% , P>0.05). (2) Compared with pre-treatment days, levels of prealbumin and transferrin in serum of patients in 2 groups on 7th and 14th post-treatment days were significantly increased (P<0.05 or P<0.01), but there was no significant difference between 2 groups. The level of total serum protein on 14th day of treatment of patients was significantly increased in both groups, and that of EIN group (66±7 g/L)was significantly higher compared with that in EN group (64 ± 11 g/L, P<0.05). The level of serum albumin (29±5, 32±5 g/L, respectively) of patients in EIN group on 7th and 14th day of treat-ment were significantly higher than that (26±4 g/L, P <0.05) in pre-treatment days, however there was no significant difference in EN group. (3) There was no significant difference in respect of hepatic function, renal function, and fasting-blood glucose between pre-treatment and post-treatment periods in both groups (P>0.05). (4) The ratio of CD4+ , CD8+ on 14th day of treatment in EIN group was close to that of pre-treatment level. In EN group, cell percentage of CD4+ significantly decreased, while that of CD8+ significantly increased (P<0.05), and CD4+ was significantly higher [(56±8) %] in EIN group than that in EN group [(55±12) % , P <0.05]. In both groups, cell percentage of CD3+ was significantly higher than that in pre-treatment days (P<0.05), while there was no obvious change in CD4+/CD8+. Conclusions Arginine enriched enteral nutrition can effectively improve nutritional status and cellular immune function of burn patients.
