Considering that the problems of low efficiency and credibility in traditional honey traceability, this study constructed a solution that combines blockchain technology and InterPlanetary File System technology to establish a highly reliable honey traceability system after analyzing the honey traceability standards. Firstly, this study introduced a hierarchical storage strategy to enhance the efficiency of on-chain information and traceability; Subsequently, this approach employs a multi-chain architecture to isolate data. It utilizes a proxy re-encryption scheme based on external random oracles, whereby ciphertext re-encryption is executed through smart contracts. Simultaneously, message authentication codes are integrated to effectively address challenges such as low information credibility, forgery, and potential privacy data leaks. Lastly, this paper proposed a pre-commit mechanism to prevent inconsistencies in data caused by sudden loads, that is, the scheme of "high-traffic package pre-commit, low-traffic supplementary on-chain".To assess the feasibility of the proposed solution, simulations and tests were conducted using Apache Bench tools. The results demonstrate that the scheme effectively achieves the chaining of basic data, controllable supervision, and credible traceability. Furthermore, it fulfills the multi-level requirements of enterprises, regulatory authorities, and users. [ABSTRACT FROM AUTHOR]

Objective: To investigate the effect of imperatorin (IMP) on the immune function of bladder cancer bearing mice by regulating the growth arrest specific protein 6 (Gas6)/Axl axis. Method: 12 mice were randomly selected from 60 SPF grade male C57BL/6 mice as the control group (CON group). The remaining mice were evenly divided into Model group, IMP group, Gas6 group, and IMP+Gas6 group, with 12 mice in each group. A concentration of 0.2 mL was injected subcutaneously into their left forelimb at a concentration of 1x107/mL murine bladder cancer cell line T739 cell solution (model group and IMP group were injected with T739 stable transfection cell line of control vector, Gas6 group and IMP+Gas6 group were injected with T739 stable transfection cell line expressing Gas6) for modeling. After successful modeling, the IMP group and IMP+Gas6 group received intraperitoneal injection of 5 mg/kg of IMP. The CON group, Model group, and Gas6 group were injected with an equal amount of physiological saline via intraperitoneal injection, once every 2 days, for 5 consecutive times. Measure the volume and weight of mouse tumors. Measure thymus index and spleen index. Serum interleukin-2 (IL-2), y Interferon (IFN-y), vascular endothelial growth factor (VEGF) levels were detected by enzyme linked immunosorbent assay (ELISA). Hematoxylin eosin (HE) staining was used to examine the pathological changes of tumor tissue. T cell subpopulations was detected by flow cytometry. TUNEL staining was used to detect cell apoptosis. Western blot (Western blot) was used to detect the expression of Gas6/Axl pathway related proteins. Results: The tumor cells in Model group were loosely arranged, with pyknosis and Karyorrhexis in different degrees. IMP can reverse this phenomenon, making the tumor cell arrangement become compact again, the degree of nuclear pyknosis increases, and the Karyorrhexis phenomenon decreases. The model group showed a significant increase in tumor volume, tumor mass, CD8+ cell percentage, Gas6, Axl protein levels, and VEGF levels compared to the CON group (P<0.05), as well as thymus and spleen indices, IL-2, and IFN-酌, the percentage of CD4+ cells, CD4+ /CD8+, and tumor cell apoptosis rate significantly decreased (P<0.05). Compared with the Model group, the IMP group had thymic index, spleen index, IL-2, IFN-酌, the percentage of CD4+ cells, CD4+ /CD8+ cells, and tumor cell apoptosis rate significantly increased (P<0.05), while tumor volume, tumor mass, percentage of CD8+ cells, Gas6, Axl protein levels, and VEGF levels significantly decreased (P<0.05). The results of the Gas6 group showed opposite trends to those of the IMP group. The results of IMP+Gas6 group showed that IMP could reverse the tumor promoting effect of overexpression of Gas6 on bladder cancer bearing mice. IMP may improve the immune function of bladder cancer bearing mice by down-regulation of Gas6/Axl signaling pathway, thus producing anti-tumor effect. [ABSTRACT FROM AUTHOR]

To solve the problem of reservoir damage in coalbed methane development, a hyperbranched polymer temporary plugging agent MTA was developed based on the theory of reservoir protection by temporary plugging. The synthesis of MTA involves the use of raw materials such as methyl methacrylate, methyl acrylic anhydride and tert-carboxyl betaine etc. The performance of MTA was evaluated in laboratory experiment. IR spectroscopy shows that the three monomers have successfully copolymerized to form a new polymer. The thermal decomposition temperature of MTA is 252 ℃. Physical-chemical performance analysis results show that MTA has a molecular weight of 6 × 104, an amine number of 17.52, a pH of greater than 7.0 and an average particle size of 0.69-3.32 μm. Compared with the commonly used plugging agents, MTA has better ability in reducing pressure transmission. The capacity of MTA in inhibiting the swelling of clays is equivalent to the inhibitive capacity of polyamines; it reduces the interlayer space of a clay from 1.92 nm to 1.58 nm. Under the action of a differential pressure, MTA can plug the micropores in formation rocks to stop the invasion of water into the formation. Furthermore, MTA can be adsorbed onto the surfaces of a rock by the action of electric charges, thereby forming a layered structure to hinder the filtration of water molecules into the rock. Evaluation of MTA reveals that MTA has good compatibility with other additives in a working fluid, and reduces the amount of filtrate of the work fluid by 41.2%. At 150 ℃, MTA working fluid has excellent performance sustainability and contamination resistance; it is resistant to contamination by 10% NaCl, or 5% CaCl2, or 10% clays of poor quality. Rock samples treated with the MTA fluid have their permeability recovered by 87.3%. In field operations, MTA showed excellent performance in maintaining borehole stability; the rate of hole washout was less than 5%. [ABSTRACT FROM AUTHOR]

Impurity separation test is widely used to detect the impurity rate of seed cotton in purchasing, due mainly to the fact that some foreign matter can be picked manually. However, the average consuming time is 20-30 minutes for a cotton sample test in a conventional raw cotton analyzer. A new testing procedure is, therefore, necessary to rapidly detect the impurities rate, and thereby to classify the seed cotton for high production efficiency. In this study, an intelligent measurement system was developed using machine vision to detect the impurity rate of machine-picked seed cotton in acquisition. The whole system consisted of a drive transmission unit, a cotton pressing unit, a sensor unit, a machine vision system, and a control system. A cleaning machine for large impurities was utilized to mechanically remove the cotton stems and hulls from the 500 g sample of seed cotton. The cotton sample without large impurities was weighed, and then transported into the machine vision system. The surface of seed cotton was automatically compacted by the pressing unit, aiming to reduce the influences of uneven brightness and shadows in subsequent image acquisition. The RGB double-sided imaging was selected to acquire the image of seed cotton. The homomorphic filtering and Principal Component Analysis (PCA) were selected to preprocess the collected RGB images. A local adaptive threshold was then utilized to segment the preprocessed images into the impurities and cotton. After that, the segmented regions of impurities were calculated to predict the weight of small impurities. The total weight of impurities was equal to the predicted value of small impurities and the measured value of large impurities. The rate of small impurities was the ratio of predicted value to the sample weight without large impurities. The final impurity rate was achieved for the total weight of impurities in the total 500 g sample of seed cotton. Linear regression (LR) and support vector regression (SVR) models were used to compare the predicted accuracy. The LR achieved a better performance, where the determination coefficient R2 for the final impurities rate was 0.95, and the root-mean-square error was 0.58%. The mean absolute error of the final impurity rate was 0.36 percentage points of 100 extra testing samples. The processing time was 48.38 s for a single detection of sample impurity rate. The findings can provide a sound reference to the measuring equipment for the impurity rate of machine-picked seed cotton during the acquisition process. [ABSTRACT FROM AUTHOR]
