The microarray of digestive tract tumors (esophagus, stomach, colon, rectum, liver, and pancreas) and adjacent tissues was used to compare and analyze the differential expression of TAF1L, STOML1, and STOML2 proteins in cancer and adjacent tissues, as well as their association with carcinogenesis. The results showed that STOML2 was significantly overexpressed in six types of digestive system cancer tissues: esophagus, stomach, colon, rectum, liver, and pancreas (P<0.001), The expression of STOML1, a member of the same family, was significantly increased only in esophageal cancer and liver cancer (P<0.005). In addition, except for pancreatic cancer, TAF1L was also highly expressed in other five digestive system cancers (P<0.005). At the same time, TAF1L, STOML1 and STOML2 were co located with MMP9, a key protein for epithelial mesenchymal transformation STOML1 and STOML2 may have extensive cancer promoting effects in various cancer tissues. Due to the different expression levels of the three proteins in various cancer tissues, it indicates that they each have tissue specificity and have different functional missions. Further research is needed to investigate the molecular pathological potential of TAF1L, STOML1, and STOML2 proteins in the occurrence and development of digestive system malignant tumors. If they can be developed for precise diagnosis

Abstract: With the aim of investigating the non-uniformity of the temperature field of electrically heated water in a horizontal stationary circular tube, we numerically simulated the axial and radial temperature fields in a horizontal circular tube using the Fluent CFD package. We then designed a sectioned grouping heating scheme based on a twoposition controller for experimental verification. The results show that the axial temperature in the tube is nonuniform if the tube is not placed horizontally. In the heating stage, uniform heating of the entire tube surface leads to significant vertical temperature stratification, with higher temperature in the upper part and lower temperature in the lower part of the circular tube. However, heating only the lower half of the tube's surface can reduce the temperature difference between the upper and lower layers from more than to less than , effectively improving the uniformity of the temperature field. During steady-state operation, due to the limitations of the two-position controller algorithm, the radial temperature deviation rises to a maximum of for the sectioned grouping heating mode. Compared with the whole-tube uniform heating mode, the grouping heating mode, especially the four-group heating mode, has obvious advantages with regard to the time to reach steady-state and the uniformity of the steady-state temperature field. This paper provides a reference for the design of heating schemes for horizontal isobaric closed circular tubes with high precision, minimal overshoot and good temperature field uniformity.
