Bulk grain categorized storage, is a modern grain storage technology with the aims to meet the requirements of optimal purchase, storage, and sales, guided by grain usage and quality control. The increase of high-quality grain supply represents the development direction of refined management in grain storage. The determination of the storage capacity of a single warehouse is directly related to the types, grain varieties, uses of grain, and quality control technology in the process of discharging the warehouse. Based on the analysis of the grain storage use, the problems existing in the sales and the acceptance capacity of customers, it is addressed that the size of the grain storage single warehouse for different grain varieties and different uses should be matched with the acceptance capacity of the sales destination. Under the existing technical conditions, the relevant opinions and suggestions were preliminary proposed on the appropriate single warehouse capacity scale, which could match the customer acceptance capacity, the grain storage quality control technology and the research on grain warehouse type.

Small cell carcinoma of the urinary bladder is very rare. Small cell carcinoma of the urinary bladder is a mass with swiftly aggressive and metastatic, and with a poor prognosis. Due to its scarcity, no forward-looking researches assessing the most effective treatment have been issued in the medical literature. It can happen either in connection with urothelial (transitional cell) carcinoma or in a pure form. Its treatment should include surgery, chemotherapy and radiotherapy. In this article, we report a case occurring in a mixed form in the urinary bladder diverticulum and we concisely review the published literature with respect to the clinical manifestation, pathology, differential diagnosis, treatment and prognosis.

This study was aimed to investigate the effect of piceatannol (PIC) on the proliferation and apoptosis of bladder cancer cell line EJ, and the underlying mechanism.   Bladder cancer cell line EJ was incubated with different concentrations of PIC, and CCK-8 method was used to determine the effect of the treatment on cell proliferation. The effect of PIC on cell cycle, apoptosis and the expressions of related signal pathway proteins were determined using Western blotting. Flow cytometry showed that PIC inhibited the proliferation of EJ cells in a concentration- and time-dependent fashion. Moreover, EJ cells were significantly blocked in G0/G1 phase, when compared with the blank control group (p < 0.05). In addition, PIC enhanced apoptosis of EJ cells in a concentration-dependent manner (p < 0.05). Results from western blotting showed that, compared with the control group, PIC upregulated the protein expression of PTEN, but downregulated Akt protein phosphorylation, relative to control cells. PIC significantly inhibits the proliferation of EJ cells and enhances their apoptosis through a mechanism related to the activation of PTEN/Akt signaling pathway.
