目的探讨降钙素原、C-反应蛋白在慢性阻塞性肺病合并细菌感染中的诊断价值。方法随机选取该院2014年6月—2015年9月收治的慢性阻塞性肺病患120例,通过肺CT检查结果分为感染组60例,未感染组60例,另选取60名体检健康者作为正常对照组,分别测定其血清降钙素原(PCT)、C-反应蛋白(CRP)浓度,对感染组和未感染组患者使用抗菌药物一段时间后,再次测定PCT、CRP,并记录结果。结果感染组治疗前PCT为(2.49±2.87)μg/L、CRP浓度为(73.79±18.29)μg/L,与未感染组、正常对照组相比,差异有统计学意义(P0.05);治疗后感染组PCT浓度为(1.98±0.11)μg/L,明显高于未感染组(P0.05)。结论血清PCT联合CRP检测是诊断慢性阻塞性肺病患者是否合并细菌感染的较敏感的特异性指标,具有一定的临床指导意义。

在实验性鼠结核病中,通过脾脏的活菌计数对长效利福霉素,利福喷丁(RPe)和FCe22807(FCe)的有效性进行了研究。用结核分支杆菌H37R_v株感染两周后,采用异烟肼25mg/kg、利福平10mg/kg和吡嗪酰胺150mg/kg,每日给药进行治疗持续6周。此后将小鼠分组,给RPe或FCe间隔分别为1周、2周或3周,化疗18周和24周后进行脾脏活菌计数。实验1显示RPe的剂量很有效,在每周给药1次的方案中,16mg/kg的剂量迅速灭菌,10mg/kg灭菌作用不十分迅速,6.25mg/kg作用不完全。RPe每2周或3周给药作用小,每2周给药16mg/kg其作用尽管与6mg/kg每周给药相同。第二个实验比较了RPe和FCe每次给药12mg/kg或8mg/kg。8mg/kg每2周或3周给药结果相似,尽管FCe较RPe作用稍强。血清分析表明8mg/kg及12mg/kgFCe的血清水平甚至低于6.25mg/kgRPe所产生的水平。这提示如果FCe的生物利用度可以提高,该药可能是较RPe更好的药物,并且服用16mg/kgRPe后的血清水平与人服用8mg/kg同时摄入富有脂肪的食物后的水平相似,提示在人类治疗中有效的2周给药1次的良好前景,对长效利福霉素在肺结核治疗管理中可能发挥的作用进行了讨论。

脊柱后路截骨矫形术治疗脊柱后凸畸形的临床分析

第十五届全国泌尿外科学术会议

Introduction and Objective: There is increase recognition of the role of various parameters measured by non-contrast computerized tomogram (NCCT) in predicting treatment outcomes of urinary stone by shockwave lithotripsy (SWL). In our previous analysis, a clinical algorithm, based on stone volume (SV), mean stone density (MSD) and skin-to-stone distance (SSD), was formulated. (j Urol 2007;177 supp: A1316) Therefore, we would like to use our subsequent patients to validate the usefulness of this algorithm. Methods: After our first part of study, a further prospective collection of data from patients diagnosed to have solitary upper ureteral stone by NCCT and received primary SWL was performed. The primary outcome was the stone free rate at 3-month after one session of SWL by Sonolith 4000+. Pre-treatment NCCT were reviewed by a single radiologist with SV, MSD and SSD measured. These patient parameters were then applied into our algorithm to assess its validity in predicting treatment outcome. Results: 37 patients (24 males and 13 females) were recruited. The overall stone free rate was 45.9%. By applying the algorithms, for patients with either SV ≤ 0.2cc or MSD ≤600 or SDep ≤ 85mm, the stone free rate was 52.2% (95% CI 31.7%, 72.7%). For those patients without any favourable factors, the stone free rate was 35.7% (95% CI 10.6%, 60.8%). Although the difference was not statistically significant, a trend of difference can still be observed in this small sample. Conclusions: Clinical algorithm based on the measurement of stone volume, mean stone density and skin to stone distance from NCCT can help to predict the treatment outcome of SWL in upper ureteral stone.
