Morphological changes of blood spleen barrier in portal hypertensive spleen

The pathogenesis of hypersplenism and the immune function of the spleen in patients with portal hypertension （PH） remain obscure. This study aimed to evaluate the morphological changes of blood spleen barrier in spleen with hypersplenism due to PH and provide evidence for an in-depth investigation of the immune function of the spleen with hypersplenism and the mechanism of hypersplenism. Methods Spleen samples from 12 portal hypertensive patients and 4 patients with traumatic ruptures of spleen were examined. The samples of spleen were made into pathological sections, stained with Masson trichrome stain, Gomori stain, and CD68, CD34 immunohistochemistry, and were examined microscopically for the changes in the distribution of collagen fibers, reticular fibers, macrophages, and vascular endothelial cells. The changes in ultrastructure of macrophages and endothelial cells in marginal zone were also evaluated by transmission electron microscopy. Results As compared to the normal spleen, the density of macrophage in the PH spleen was decreased, but the macrophages were mainly located in the marginal zone and distributed around the splenic corpuscle, with many villi and pseudopodium-like protrusion on the cell surface. The accrementition of collagen fibers was obvious around the splenic corpuscle and central artery. The increased reticulate fibers encircled the splenic corpuscle with more connection between the fibers. The vascular endothelial cells were in diffused distribution, without any regionality in PH spleen, but the vessel with enlarged lumina increased in red pulp. Conclusions The morphological changes of the blood spleen barrier can be one of the pathological fundaments for the abnormality of the immune function and the increased destruction of blood cells located in the spleens of patients with PH However. this still entails clarification.     

Laparoscopic splenectomy by secondary pedicle division strategy: a highly cost-effective method

Background Laparoscopic splenectomy （LS） shows many advantages compared with open surgery except for the high cost. This study was aimed to recommend secondary pedicle division strategy as a method with high cost-effectiveness. Methods From January 2003 to June 2005, 14 consecutive patients underwent laparoscopic splenectomy. The splenic pedicle was controlled by secondary pedicle division strategy in 8 cases and by Endo-GIA in the other 6 cases. A retrospective study was carried out to evaluate the operative time, blood loss, time to diet, operative morbidity, postoperative stay, and operative cost.
Results LS was performed successfully in a total of 14 cases. There was no significant difference between the two strategies in operative time, blood loss, time to diet, operative morbidity and postoperative stay. The operative cost of secondary pedicle division strategy group （RMB 8354.38±752,10） was significantly lower than that of Endo-GIA group （RMB 11053.33±602.27） （P〈0.01）.
Conclusions Laparoscopic splenectomy by secondary pedicle division strategy is a safe, effective and economical procedure with the value of popularization in developing countries.

脾虚证大鼠胃、肠电—机械活动异常与CCK，SS含量变化的关系

目的：探讨脾虚证时胃肠激素改变与胃肠运动异常之间的关系,方法：采用放射免疫分析法测定实验性脾虚证大鼠不同造模时间（7d,14d),胃窦,十二指肠,空肠,下丘脑及血浆中生长抑素（SS）,缩胆囊素（CCK）含量并与正常对照组和四君子汤预防组比较,通过体内埋藏电极和传感器记录胃,肠电－机械活动进行造模前后自身比较,结果：脾虚早期（7d),SS在下丘脑,血浆中含量升高,外周组织中含量下降（P＜0．01）,CCK在组织和血浆中含量均升高（P＜0．01）,胃电一机械活动节律,振幅均下降（P＜0．01）,肠机械活动节律,振幅均升高（P＜0．01）,电慢波节律下降,振幅升高（P＜0．01）,脾虚晚期（14),SS在下丘脑,血浆中含量下降,外周组织中含量升高（Ｐ＜０．０１）,CCK参下丘脑及胃窦组织中含量升高（Ｐ＜０．０１）,在血浆和肠道组织中含量下降（Ｐ＜０．０１）,胃机械活动节律下降（Ｐ＜０．０１）,振幅改变不明显,电慢波节律,振幅均下降（Ｐ＜０．０１）,肠电一机械活动节律,振幅均下降（Ｐ＜０．０１）,经四君子汤预防性治疗的动物体内激素含量及胃,肠电一机械活动变化均无显著意义,结论：脾虚证时胃肠激素改变与胃肠运行异常之间存在内在联系,且随病程发展呈动态变化,四君子汤对此有纠正作用。
