METHODS Human fresh surgical colonic mucosa was homogenized by adding appropriate amount of normal saline and centrifuged at 3000 r/min. Protein content of the supematant was measured and then mixed with Freund adguvant, and injected into the plantae of the model group rats, then into the plantea, dorsa, inguen and abdominal cavities (no Freund adjuvant for the last injection) on the 10 th, 17 th, 24 th and 31 th day respectively. When a certain titer of seurm anti colonic antibody was reached, 20 ml/L formalin and antigen fluid (no Freund adjuvant) were administered by enema to set up ulcerativecolitis rat model. The arimals were randomly divided into four groups: model control group (MC=8), electropuncture group (EP=8), herb separation moxibustion group (HPM=8) and normal control group (NC=8) HPM: Mosa cones made of refined mugwort floss were placed on the medicinal pads (medicinal pad dispensing: Radix Aconiti Praeparata, contex Cinnamomi, ectc) for Qihai (RN6) and Tianshu (ST 25, bilateral) and ignited. Two moxa cones were used for each acupuncture once a day and 14 times in all. EP: Tianshu (bilateral) and Qihai were stimulated by the intermittent pulse with 2 Hz frequency, 4 mA intensity for 20 minutes once a day and 14 times in all. After treatment, all rats were killed simultaneously. The spleen was separated and distal colon was dissected. Totai tissue RNA was isolated by the guanidinium thiocyanate phenol chloroform extraction method. RT PCR technique was used to observe the expression of IL 1 β and iNOSmRNA. no Freund adjuvant. RESULTS IL 1 β and iNOSmRNA was not all detected in the spleen and colonic mucosa of NC rats, while it was significantly expressed in that of MC rats. IL 1 β and iNOSmRNA was markedly lower in EF and HPM rats than that in MC rats. There was no significant difference in the levels of IL 1 β and iNOSmRNA between EP and HPM rats.

文摘目的探讨微创切口在开胸手术中的临床价值。方法对49例胸部手术患者,22例采取腋下纵形、横形微创切口,27例在传统开胸手术下完成,比较两种术式C反应蛋白(C reactive protein,CRP)、肺功能和临床指标的变化。结果两组患者术后血清CRP浓度明显升高,第1d达到峰值,微创切口组CRP术后1d(56.1±10.9)mg/L,显著低于传统开胸组(73.8±15.1)mg/L(t=-4.603,P=0.000)。两组术后肺功能每分钟通气量相对值minute ventilation volume,MV、1s用力呼气容积相对值(forced expiratory volume in one second,FEV1)下降,术后1周时微创切口组MV为(95.6±16.4)L,显著高于传统开胸组(81.9±12.7)L(t=3.296,P=0.002),微创切口组FEV1为(57.1±5.7)%显著高于传统开胸组(51.4±6.9)%(t=3.105,P=0.003)。结论与传统开胸手术相比,微创切口可明显减轻患者的手术创伤,术后肩关节和上肢活动受影响少,恢复快,对肺功能影响小,切口位于腋下隐匿、美观,组织损伤小,尤其适合青少年及女性患者。
