AIM： There is strong evidence that interleukin-11 （IL-11） is involved in the regulation of tumor progression, cellular growth and differentiation. Recently, interleukin-11 receptor （IL-11R） has been detected on some cancer cells. In this study, we investigated the expression of IL-11 and IL-11R in colorectal adenocarcinoma. METHODS： To elucidate the involvement of IL-11 and IL-11Rα in human intestinal adenocarcinomas, we examined 115 cases of surgically resected human colonic adenocarcinoma and 11 cases of adenoma by immunohistochemistry and Western blotting. RESULTS： Among 115 cases of adenocarcinoma, 100 cases （87.0%） showed positive staining in the cytoplasm of carcinoma cells for the IL-11, and 87 cases （75.6%） were positive for the IL-11Ra. Six cases （54.5%） and four cases （36.4%） of 11 adenomas were positive for IL-11 and IL-11Ra, respectively. The expression of IL- 11Ra correlated with the histological differentiation （P=0.033503）, the depth of tumor invasion （P= 0.006395）, Dukes＇ classification （P= 0.015648） and lymphatic invasion （P= 0.003865）. However, the expression of IL- 11Rα was not correlated with the venous invasion and the presence of lymph node metastasis. The expression of IL-11 was not correlated with any clinicopathological factors. In Western blot analysis, two human colorectal carcinoma cell lines and four tissues of surgically resected human carcinoma expressed both IL-11 and IL-11Rα proteins. CONCLUSION： IL-11 and IL-11Rα are highly expressed in human colorectal adenocarcinoma and the IL-11Rα expression is correlated with clinicopathological factors, These findings suggest that the expression of IL-11Rα is an important factor for the invasion of human colorectal adenocarcinoma.

This study examines the impact of different CO2 injection methods on coalbed methane recovery. Specifically, this study investigated the effectiveness of continuously injecting CO2 versus injecting CO2 that had been soaked for two weeks. The objective was to ascertain which approach was more successful in enhancing CO2 Enhanced coalbed Methane (CO2-ECBM). The experiment involved injecting 3 MPa of CH4 into dry coal samples, allowing it to adsorb until reaching equilibrium, and then injecting 5 MPa of CO2 to recover adsorbed CH4. The continuous method recovered CH4 without detectable effluent concentration for 5 hours, but desorption efficiency was only 26% due to fast flow. On the other hand, the desorption efficiency of the cyclic method was only 12%, indicating trapped CH4. A comparison of desorption efficiency per unit of time shows the continuous method is more effective than the cyclic method. The results of this study demonstrate the continuous method is more effective for the desorption of CH4, and its efficiency can be improved by briefly soaking CO2 on coal and then reinjecting it to maximize CH4 recovery. It is advisable to limit the soaking time to prevent excessive swelling of the coal matrix, which can hinder seam flow and harm long-term gas production.
