The invention relates to an abrasive material jet injection device which is provided with a spray gun for injecting abrasive material jet, wherein the spray gun is provided with at least two nozzles, and the spray gun is connected with an oil tube. The abrasive material jet injection device has simple structure and is easy to assemble and maintain. The key part (nozzle) in the device has longer service life so as to satisfy the requirements of two operations of perforating and fracturing. Because a check valve and a sieve tube are arranged, the phenomenon that the nozzle of the injection device is subjected to sand jamming can be greatly lowered; meanwhile, when the device is subjected to sand jamming faults, base fluid is pumped into the annulus of an annular tube, the base fluid enters the injection device via the check valve by the sieve tube, which is convenient to flush the device, and therefore the well can be subjected to backflushing to ensure that the operation is successfully carried out. Because a packer is omitted, construction equipment is simplified. According to the abrasive material jet injection device, the defect of the known technology is overcome, abrasive material jet pore forming and fracturing are combined, and therefore layering can be precisely carried out in a vertical well or sectional fracturing can be precisely carried out in a horizontal well section.

The present invention provides a novel method for diagnosing, monitoring, prognosing and staging Lymph Node (LN) status in colorectal cancer (CRC) that is more sensitive and accurate than conventional detection technologies such as histopathology. The Guanylyl Cyclase C (GCC) gene is specifically expressed in apical epithelial cells of the GI tract from the duodenum to the rectum and the detection of GCC mRNA in LNs is indicative of the presence of metastases. Quantitative RT-PCR (RT-qPCR) detection of GCC mRNA to identify the presence of colorectal cancer (CRC) cells in LNs has the potential to aid in CRC staging. When used in combination with glucuronidase B (GUSB), accurate quantification of GCC can be achieved with less than a 2-fold variation between intact and highly degraded RNA specimens. The invention also relates to a newly designed GCC/GUSB assay that uses relative quantification having improved prognostic value for time to recurrence and relapse-free survival in Stage I or II colon cancer patients. The GCC/GUSB assay also improves the statistical power of prognosis stratification for relative risk of recurrence and relapse-free survival.

A method of modifying the optical properties of a processed nitride semiconductor light-emitting device initially comprises disposing the processed nitride semiconductor light-emitting device in a vacuum chamber. One or more nitride semiconductor layers are then grown by molecular beam epitaxy thereby to modify the optical properties of the processed light-emitting device. Activated nitrogen, for example from a plasma source, is supplied to the vacuum chamber during growth of the nitride semiconductor layer(s). The use of activated nitrogen reduces the growth temperature required for the growth of the nitride semiconductor layer(s), as the need for thermal activation of a nitrogen species is eliminated. Moreover, use of a growth method such as, for example, plasma-assisted MBE to grow the nitride semiconductor layer(s) allows much more precise control of their thickness and composition.
