Objestive Systemic inflarmmation may be triggered by injury, hypothermia, ischemia-reperfusion and the contact of the blood with foreign body during cardiopulmonary bypass (CPB). To determine the application values of gene chip technique in the clinical practice and the study of cardiovascular stagery, as well as to provide clues to the study of inflammatory responess during CPB, microarry for gene expression profiles was used to identify the differences in the gene expression of myocardium between pre-and post- CPB. Methods Six adult patients who underwent CPB from March to May in 2003 were involved. Samples of right atrium were col- lected before and at immediate end of CPB. BD AtlasTM cDNA Expression Arrays was used to identify the differences in the gene ex- pression of cytokines. The results were compared with that of semi-quantative RT-PCR. Resellts The mean age of 6 patients (5 males and 1 female) was (32.67± 11.72) years. The baseline heart function was gradeⅡin 3 cases and grade Ⅲ in 3 other cases. The baseline left ventricular ejection fraction(LVEF)was (58.17±7.91)%. The mere duration was (91.67±43.88) minutes for CPB and was (58.67±43.46) minutes for aorta blocking. The minimum nasopharynx/rectal temperture was (29.37±1.90)℃/ (32.15±1.52)℃. Gene expression profiles of cytokines in the myocardium pre- and post-CPB were analysed successfully. The ex- pression of IL-6, IFN-γ,Wnt5a, TNFRSF1B, a member of tumor necrosis factor receptor superfamily, PIGF and MFNG in the myo- cardium were unpregulated after CPB. Conclusion Microarray technique is applicable in the study of cytokines changes dying CPB. cDNA microarray identified pleliminarily the differences in the gene expression between pre- and post-CPB. These genes may be in- valved in inflammation and other psthophysiological responses incuced by CPB. The myocardiym is probably one of the major sources of cytokines during CPB. Further study may be helpful in understanding the llngthe development of inflammation during CPB, and eventually, reducing the post-operative complications. 相似文献

Current medical procedures used in prenatal screening and diagnosis of handicapping conditions are reviewed. These strategies include ultrasound, amniocentesis, chorionic villus biopsy, restriction enzyme analysis, maternal serum analysis, fetoscopy, and fetal serum analysis. Along with an explanation of each method, advantages, disadvantages, and risks involved with each are provided. An understanding of these procedures by medical and educational personnel is encouraged, and the potential benefits of prenatal identification of handicapping conditions are emphasized. 相似文献

OBJECTIVE: As more patients are diagnosed with prostate cancer at an early stage, it is becoming increasingly important to refine the technique of surgical excision. For this purpose we have generated objective data comparing three different surgical approaches used by three experienced surgeons. METHODS: We prospectively compared three contemporary personal series of 50 consecutive radical prostatectomy (RP) patients. The health-related quality of life was evaluated preoperatively and in months 1, 3, 6, 12 and 24. RESULTS: Considering in turn the patients undergoing retropubic, perineal and laparoscopic RP, the median procedure time was 2 h and 27 min, 1 h and 50 min and 4 h, with a transfusion rate of 2, 0 and 8%, respectively. In the perineal group there were more wound infections. Median catheter drainage was 7, 10 and 7 days and zero, 13 and one patients needed reinsertion of a catheter. Early continence varied considerably, with 57.4, 11.4 and 6.3% of patients pad-free after 1 month, but there were no differences in social continence (zero or one pad) with 97.8, 97.8 and 91.9% after 2 years. The Litwin score for incontinence (preoperative minus postoperative) was -24, -41 and -63% after 1 month and -13, +3 and -29% after 2 years. Twenty-nine, five and 15 patients had a preoperative five-item version of International Index of Erectile Function (IIEF-5) score of > or = 17 points and a nerve-sparing procedure. After 2 years, 48.1, 0 and 0% had an IIEF-5 score of > or = 17 points without the use of phosphodiesterase type 5 (PDE-5) inhibitors, but when including patients using inhibitors there were no significant differences. CONCLUSIONS: A comparison of morbidity, short-term convalescence and long-term side-effects of different surgical techniques is strongly biased by both the preoperative status of patients and the skill of the surgeons. Overall, we found some differences in the short-term results (e.g. early continence) and comparable long-term results. 相似文献

目的总结瓣膜置换患者行胆道手术的术前用药方法。方法对38例瓣膜置换后在服用华法令过程中因胆道疾病需行择期手术治疗的患者随机分为2组,肝功能正常组(A组)23例、肝功能不正常组(B组)15例均于术前3d停服华法令,B组术前12h肌注VitK110mg。术前无应用华法令历史的患者115例做为对照组。结果38例患者停药2d后A组血浆凝血酶原时间与对照组差异无显著意义,B组于术前12h肌注VitK110mg后,血浆凝血酶原时间与对照组相比差异也无显著性意义。结论瓣膜置换患者在抗凝期间行胆道手术,只要准备充分,围手术期是安全的。 相似文献
