腹膜后自体脾移植术对肝硬化门静脉高压症脾脏免疫功能的影响

肝硬化门静脉高压症为全球性疾病,国内一般采用脾切除联合断流术治疗脾亢和(或)食管胃底曲张静脉破裂出血。脾切除术不仅丧失脾脏免疫功能,而且对肝硬化门静脉高压症肝功能的进—步损害较其他条件下的切脾更为严重。我们采用随机对照的方法,研究了腹膜后自体脾移植对保留脾脏免疫功能的作用。临床资料1.一般资料:收集1979年7月至2001年8月入住我院的肝硬化门静脉高压症病人20例,男19例,女1例,年龄33~80岁(平均37.8岁),肝功能Child A~B级。术前均有不同程度的脾肿大及脾功能亢进或食管胃底曲张静脉破裂出血症状。随机分为2组,每组各10例。…     

自体脾移植联合食管横断吻合术治疗肝硬化门静脉高压症

目的 探讨腹膜后自体脾移植联合食管横断吻合术治疗肝硬化门静脉高压症的临床疗效.方法 将2003年1月至2006年12月收治的36例肝硬化门静脉高压症患者随机分为自体脾移植组(n=18)和脾切除组(n=18),自体脾移植组接受脾切除、食管横断吻合及自体脾移植术,脾切除组接受脾切除、食管横断吻合术.于术前及术后2～6个月定期观察两组患者的一般情况、行脾脏放射性核素扫描,同时检测肝功能、血清促吞噬素(Tuftsin)及IgM水平,并行组间及手术前后比较分析.结果 自体脾移植组患者术后2个月血清Tuftsin和IgM水平与术前比较无明显差异(P0.05),而脾切除组患者术后2个月血清Tuftsin和IgM水平较术前明显降低(P<0.05);自体脾移植术对患者肝功能无明显影响;术后2个月放射性核素扫描证实移植脾于腹膜后存活.结论 自体脾移植对保留机体脾脏免疫功能具有重要价值,腹膜后自体脾移植联合食管横断吻合术治疗肝硬化门静脉高压症的临床效果确切,值得推广应用.     

门脉高压症腹膜后自体单个核细胞移植治疗后门静脉压力变化的临床研究

目的探讨肝炎后肝硬化门脉高压症腹膜后单个核细胞移植对门静脉压力的影响。方法随机对肝炎后肝硬化并门静脉高压症上消化道出血的70例病人分为治疗组和对照组。治疗组36例病人行脾切除、门—奇静脉断流的同时在腹膜后植入自体骨髓单个有核细胞。对照组34例行脾切除、门—奇静脉断流。观察术后再出血率及门静脉压力变化情况,用SAS统计软件分析处理。结果 36例在手术后12个月测门静脉压力降低,随访5a无再出血病例。结论肝硬变并门静脉高压症上消化道出血病人在行脾切除,门-奇断流的同时,在腹膜后植入自体骨髓单个核细胞可以增加门静脉侧支循环,降低门静脉压力,预防再上消化道出血的发生。

Importance of echocardiography in prognosis of surgical outcomes in cholecystitis in elderly patients

The authors propose to use more often echocardiography (EchoCG) in examination of elderly (over 60 years) of age patients with cholecystitis that permits to increase surgical activity to 92.4%. Left ventricular ejection fraction is the most informative. When this fraction is lower than 45% surgery must be recommended on vital indications only. EchoCG was used in 155 patients with cholecystitis, 131 of them were operated. 2 (1.52%) patients died due to acute cardio-vascular insufficiency and pulmonary artery thromboembolism.     

脊髓胶质细胞在小鼠骨癌痛形成中的作用

Objective To evaluate the role of gliocyte in the spinal cord in the development of bone cancer pain (BCP) in mice. Methods Forty male C3H/He mice aged 8-10 weeks weighing 18-22 g were randomly divided into 4 groups ( n = 10 each) : group I sham operation (group S) , group II BCP, group Ⅲ PBS and group IV minocyline (group M) . In group BCP, PBS and M, bone cancer pain was produced by injection of NCTC2472 fibrosarcoma cell suspension (2 x 105 cells) 10 μl into medullary cavity of calcaneus bone, while in group S, PBS solution 10 μl was injected instead of cancer cell suspension. In group PBS and M, PBS 5 μl and minocyline 5 μl (dissolved to 0.2 mmol/L in PBS)_were given IT immediately before cancer cell inoculation once a day for 11 consecutive days respectively. Mechanical pain threshold was measured at 1 d before cancer cell inoculation, and at 0, 3, 5, 7, 9 and 11d after cancer cell inoculation. Cold pain threshold was measured at 3, 7, 9 and 11d after cancer cell inoculation. The animals were killed after measurement of pain threshold and L4-6, segment of spinal cord was removed for determination of GFAP and CD11b expression by Western blot. Results Compared with group S, mechanical pain threshold was significantly increased at 3-11 d after cancer cell inoculation in group BCP and PBS, and at 3 and S d after cancer cell inoculation in group M, and cold pain threshold was significantly increased at 7-11 d after cancer cell inoculation, and expression of CD11b and GFAP was up-regulated in group BCP, PBS and M ( P < 0.05) . Compared with group BCP, mechanical pain threshold was significantly decreased at 3-11 d after cancer cell inoculation, cold pain threshold was significantly decreased at 7-11 d after cancer cell inoculation, and expression of CD11b and GFAP was down-regulated in group M ( P <0.05) . ConclusionThe activiton of gliocyte in the spinal cord is involved in the development of bone cancer pian in mice.
