As an essential component of agricultural branding, the construction of brands for agricultural and livestock products is a crucial lever for transforming traditional production and management methods and adjusting the agricultural industry structure. It plays a key role in implementing the strategy of building a strong nation through brands and promoting the construction of Chinese-style modernization. Practice has shown that Chinese policies for constructing brands of agricultural and livestock products are gradually improving, brand cultivation is gaining momentum, the strength of livestock brands is gradually increasing, and the foundation for brand construction is becoming increasingly solid, to lay a solid foundation for the high-quality construction of agricultural and livestock product brands. Towards Chinese-style modernization, key tasks in building agricultural and livestock product brands include strengthening the main forces in brand construction, enhancing brand influence, reinforcing the processing capacity of agricultural and livestock products, and perfecting the quality traceability system. To accelerate the creation of high-end agricultural and livestock product brands and contribute to the construction of an agricultural powerhouse, it is necessary to actively cultivate and guide to strengthen the main forces in branding, enhance brand influence by omni-channel efforts, expand the industrial chain to improve the processing capacity of agricultural and livestock products, and adhere to standardized development to improve the quality traceability system of agricultural and livestock products.

In order to realize the resource utilization of agricultural waste waste fungus sticks (EF), KM-n04 and CuCl2 ⋅ 2H2O were used to modify EF biochar (EFBC) prepared at low temperature to prepare copper-manganese modified EFBC (Cu-Mn-EFBC). SEM, BET, XRD, FTIR, Zeta potential and EA characterization were carried out, and the effects of preparation and reaction conditions on the adsorption of tetracycline hydrochloride (TCH) in water by Cu-Mn-EFBC were investigated and the mechanism was analyzed. The results showed that the removal rate of TCH by Cu-Mn-EFBC was 90. 03%, which was much higher than that of EFBC (21.44% ), the dosage of biochar and ionic strength had little effect on the adsorption, and the pH value of the solution has a great influence; the pseudo-second-order kinetic equation and the Freundlich equation can better fit the adsorption process. The adsorption mechanism is mainly cation-π interaction, π- π interaction, hydrogen bonding and complexation reaction. [ABSTRACT FROM AUTHOR]

In order to improve the tracking accuracy of maneuvering targets and obtain more accurate real-time position and velocity information of the targets, an improved interactive multi-model tracking algorithm is proposed. Based on the traditional interactive multi-model, this algorithm introduces adjustment parameters associated with target features. The target feature data is used to provide a limited domain for the initial data, and then the adjustment parameters are added to the filter, so as to complete the optimization of the tracking accuracy by the iteration of the target state gain matrix and the covariance matrix. Experimental simulation analyzes three common states of maneuvering targets and compares them with traditional interactive multi-model tracking algorithms. The experimental results show that, when the deflection angles of the adjustment parameters of the algorithm are 4°, 2° and 1°, the mean root mean square errors are 15.91 m, 11.79 m and 11.39 m respectively, which are significantly better than the traditional algorithm's mean value of 21.39 m. At the same time, with the improvement of parameter setting accuracy, it has a certain inhibitory effect on the error fluctuation caused by the maneuvering target state. [ABSTRACT FROM AUTHOR]

The effects of processing parameters of vacuum conditioning, tobacco leaf storage, cutting, and cut tobacco roller drying processing on tobacco leaf cut tobacco product's color and lustre were studied using color difference instrument. The results showed that tobacco leaf brightness and color processed by two cycle vacuum conditioning more decreased than one, and tobacco leaf brightness and color also more decreased when conditioning temperature increased, time of keeping temperature and time of vacuum pumping longer in one cycle vacuum conditioning. Tobacco leaf brightness and color decreased more, color increases, color and lustre worse when temperature and humidity of storage environment increased and time of storage became longer. Cut tobacco brightness and color decreased more, color increased, color and lustre were worse when moisture content of tobacco and cutter mouthpiece pressure increased. The color had little influence on cut tobacco roller drying. According to the experiments results, the preferable process conditions were determined to keep excellent color and lustre of tobacco leaf and cut tobacco, which were one cycle vacuum conditioning, lighter processed strength (conditioning temperature was less than or equal to 55 °C,time of keeping temperature and vacuum pumping were less than or equal to 50 s and 70 s) ; temperature and humidity of storage environment were 26 °C and 63 % respectively, time of leaf storage was 2~8 h; moisture content of cutting was below 18.5%, and cutter mouthpiece pressure was below 0. 2 MPa, the hot air temperature was 105 °C and the temperature of the tube wall of roller was 125 °C.

Capsaicin, extracted from the pepper, is a substance having analgesic action. Through activation of the transient receptor potential vanilloid receptor 1 (TRPV1) on sensory nerve fibers, release and consumption of large amounts of neuropeptide substance, which then causes nerve cells produce desensitization reaction to noxious stimuli, capsaicin plays a long - lasting analgesic effect without affecting motor function. The formulations containing the ingredient have been applied in the clinical treatments. Specific sites of injection of capsaicin or its analogue resiniferatoxin can reduce pain in cancer patients. However, there is some overlap between the therapeutic dose and toxic dose of capsaicin, which limits its further application. Different effects may result from different routes of administration and the sites of action. To better understand the analgesic effects of capsaicin and exert its therapeutic value, this review summarizes the research results in recent years from the different routes of administration.

Objective To explore the effects of TCM pattern differentiation and treatment on brain function of patients with severe Alzheimer's disease (AD) using resting-state functional magnetic resonance imaging (fMRI). Methods According to the internationally recognized NINCDS-ADRDA Alzheimer's Criteria, fifty patients with severe AD were enrolled in the study and were randomly divided into Chinese medicine group (CMG) (n = 25) and Western medicine group (WMG) (n = 25). Patients in the CMG were given TCM treatment based on pattern differentiation: patients with heart-qi deficiency received Tiaoxin Fang (Heart-regulating Formula), patients with kidney-essence insufficiency Bushen Fang (Kidney-supplementing Formula) and patients with patterns complicated by phlegm and blood stasis were additionally given Mengshi Guntan Wan (Chlorite Phlegm-Removing Pill) and Xuefu Zhuyu Jiaonang (Blood Mansion Stasis-Expelling Capsule) respectively. Patients in the WMG were treated with donepezil 5 mg once daily. The course of treatment lasted 48 weeks for both groups. Therapeutic effects were observed and compared using Mini-Mental State Examination (MMSE) and Clinical Dementia Rating (CDR). Changes in brain function of the AD patients before and after treatment were also examined and compared with resting-state fMRI. Results After 48 weeks of treatment, 45.00% and 38.89% patients scored higher in MMSE and 30.00% and 22.22% scored higher in CDR in the CMG and the WMG respectively. The results of fMRI demonstrated better connectivity between posterior cingulate gyrus and other brain regions in both groups of patients. In CMG, the improved regions involved primarily the left frontal and parietal lobes, left temporal lobe and occipital lobe, while in WMG, the improved regions included primarily the right hippocampus, the left frontal lobe and the temporal lobes. Conclusion The heart-regulating and kidney-supplementing TCM treatment based on pattern differentiation is effective in improving cognitive function and reducing disease severity of patients with severe AD and enhancing their brain function by increasing connectivity between posterior cingulate gyrus and specific regions in the brain.
