目的：探讨Ⅲ度胫腓骨开放性骨折早期的处理方法与技巧,总结外固定支架治疗、稳定骨折端的临床效果。方法：早期采用外固定支架治疗Ⅲ度胫腓骨开放性骨折120例,男86例,女34例;年龄18～67岁,平均36.8岁。结果：120例中111例优良,或通过Ⅱ、Ⅲ期手术,软组织修复及骨折愈合良好;1例患者因感染、骨折复位不良,骨折不愈合;8例Ⅱ期截肢。结论：对于Ⅲ度胫腓骨开放性骨折早期以外固定支架为主的治疗是一种理想的方法,术中良好的骨折复位、简单的内固定合并外固定支架为主的治疗,有利于日后软组织的修复及骨折愈合。     

长托宁用于全麻术前用药的效果观察

目的:观察长托宁作为全麻病人麻醉前用药对心血管系统和呼吸道分泌物的影响.方法:随机选择20例需全麻手术病人,在麻醉诱导前静注长托宁0.015 mg/kg,观察注药前、后5、10、20分钟各时点的血压、心率、脉搏氧饱和度及口干程度以及术中术毕口腔和呼吸道分泌物情况.结果:病人使用长托宁后5、10、20分钟的血压、心率与使用前相比有下降趋势,但无统计学意义(P＞0.05),脉搏氧饱和度未见明显改变,用药10分钟病人有轻度口干,术毕拔除气管导管时口腔及呼吸道分泌物较少.结论:长托宁用于全麻病人麻醉前给药效果满意.     

肾上腺区神经节细胞瘤(附18例报告)

目的较全面的了解神经节细胞瘤的临床特点及治疗方法。方法回顾性分析18例病理确诊的神经节细胞瘤患者临床表现、实验室检查、影像学检查和治疗效果。结果15例是无临床症状的影像学偶然发现病例,内分泌检查均在正常范围;另外3例以阵发性高血压为主要临床表现,其中1例尿儿茶酚胺升高,肾上腺髄质显像(MIBG)阳性。18例B型超声检查均为低回声;13例CT平扫见散在点状高密度影,12例CT增强扫描肿瘤周边强化明显。手术前诊断为嗜铬细胞瘤12例,神经节细胞瘤4例,肾上腺无功能腺瘤2例。18例行肿瘤切除,随访6个月~7年,高血压症状消失,2例肿瘤复发。结论肾上腺区神经节细胞瘤与肾上腺髄质肿瘤难以鉴别,综合各项影像学检查对诊断有较高的参考价值。手术治疗是唯一的有效方法。     

颈性眩晕的分型治疗及疗效分析

目的 将颈性眩晕分为上、下颈性眩晕，采取不同治疗方法并与常规治疗方法的疗效比较，以寻求更好的治疗方法。方法 将135例颈性眩晕随机分为试验组和对照组，对其治愈率及治疗时间进行统计学分析。结果 试验组的治愈率高于对照组，而试验组的治疗时间短于对照组，均有统计学意义。结论 对颈性眩晕进行分型并采用不同的治疗方法能提高治愈率，缩短治疗时间。     

The effect of plasma solutes on total-body-water measurements via NMR.

Nuclear magnetic resonance (NMR) spectroscopy has been reported as an alternative method for quantitating deuterium oxide concentrations in the evaluation of total-body-water in humans. However, the presence of dissolved plasma proteins results in an underestimation of deuterium NMR (2H-NMR) intensity ratios, thereby causing an overestimation (5-6%) of total-body-water (TBW) values determined from nonsublimed patient plasma samples. We demonstrate that plasma samples must be corrected for the volume percentage of water in plasma. Correction of initial 2H-NMR intensity ratios with a factor of 0.93 results in intensity ratios comparable to those determined from plasma samples subjected to vacuum sublimation to remove all plasma solutes.     

CT在外伤性胃肠道穿孔急诊中的价值

目的:探讨急诊外伤性胃肠穿孔的CT征象及诊断价值。方法:收集18例经手术证实的外伤性胃肠道穿孔的临床资料及CT征象,分析与总结胃肠道破裂穿孔CT扫描的各种有价值的表现。结果:18例外伤急诊患者中,胃、十二指肠、空回肠与结肠穿孔各1,2,12,3例,其中空回肠为多处破裂,CT主要征象为腹腔散在积液征、游离气腹征、肠系膜与肠壁增厚模糊征、造影剂外溢征。结论:CT扫描在外伤性胃肠道穿孔急诊患者的检查中有定性诊断价值,综合分析各种征象,会明显提高CT的诊断正确率。     

p53基因(今又生~)联合支气管动脉化疗治疗肺癌15例近期疗效观察

目的探讨瘤内注射或经支气管动脉灌注p53基因联合支气管动脉灌注化疗(BAI)治疗肺癌的安全性、疗效和给药途径。方法经病理证实的15例肺癌,首先在CT引导下经皮穿刺瘤内注射或经支气管动脉灌注p53基因(今又生~),2～5天后,行BAI灌注化疗药物;然后根据病情变化再次进行基因治疗和/或BAI。治疗后常规使用螺旋CT定期复查,评价治疗效果。结果全部15例患者均完成上述治疗,并接受随访2～11个月。有效率(CR+PR)46.7%(7/15),1例肺部肿块消失,6例肺部肿块缩小,3例纵隔淋巴结缩小,1例胸水减少,仅1例观察到肿瘤长大,14例临床症状有不同程度缓解93.3%(14/15)。p53治疗后6例出现发热(38℃～40℃),未观察到基因药物的其它严重副作用,无严重操作有关并发症出现。结论本研究结果初步显示,作为肿瘤综合治疗的一部分,p53基因治疗与BAI联合应用,是一种治疗肺癌安全、有效的方法,提高了BAI的治疗效果。经皮瘤内注射p53是否为一种较好的给药途径值得进一步探讨。     

Addressing quality of life issues in adolescents: social skills interventions.

OBJECTIVE: The purpose of this study was to determine whether social skills training can improve the social interaction skills of adolescents with craniofacial conditions (CFCs) in a natural environment (school lunchroom). DESIGN: This study used a pre-post between-group comparison design. Differences between treatment and control subjects were analyzed via a repeated measures analysis of variance. SETTING: The observations were conducted in the respective school lunch-rooms of the adolescents. Social skills groups were conducted in an outpatient clinic setting. MAIN OUTCOME MEASURES: Structured data based on 45 minutes of observation was coded for type, frequency, and duration of social contact. Specific measures included subject initiations and responses, peer initiations and responses, conversation events, total positive communication, and frequency of nondirected comments. RESULTS: Both target and peer-controlled total communication improved across time with adolescents receiving social skills intervention showing significantly more improvement than those adolescents not receiving direct social skills interventions. Adolescents receiving treatment participated in significantly more target initiated conversations lasting at least three interchanges and showed a trend toward a greater frequency of target initiations and positive responses to peer initiations. Peers were more likely to respond to treatment subject initiations after intervention. Fewer treatment subjects used nondirected communication, whereas control subjects continued to use nondirected communication at a slightly increased frequency. CONCLUSIONS: This study provides preliminary evidence that social skills training can increase the frequency of positive social interactions with peers for adolescents with CFCs.
