BACKGROUND: Apoptosis is involved in the formation of degenerative joint diseases. Therefore, anti-chondrocyte apoptosis may be an effective way to treat osteoarthritis. Neferine has a wide range of pharmacological activities including anti-inflammatory, anti-tumor and anti-apoptotic activities, and its effect on OBJECTIVE: To investigate the effect of neferine on chondrocyte apoptosis induced by interleukin-1β and elucidate its possible mechanism. METHODS: (1) The rat chondrocytes at logarithmical stage were taken and intervened in five groups. The control group was cultured routinely. The model group was routinely cultured for 24 hours after treatment with interleukin-1β for 2 hours. The low-, medium-, and high-dose groups were treated with interleukin-1β for 2 hours and then cultured with 5, 10, and 20 μmol/L neferine for 24 hours, respectively. At the end of culture, cell apoptosis, chondroglycoprotein 39 and type II collagen levels in cell supernatants, mRNA and protein expression of apoptosis-related proteins, and mRNA and protein expression of proteins related to the protein kinase R-like endoplasmic reticulum kinase (PERK)/activating transcription factor 4 (ATF4) signaling pathway were detected. (2) Rat chondrocytes at logarithmic growth period were taken and divided into four groups: control group and model group were treated with the same intervention as above, drug group was treated with interleukin-1β for 2 hours and then cultured with 20 μmol/L neferine for 24 hours, and activator group was treated with interleukin1β for 2 hours and then cultured with 20 μmol/L neferine and CCT020312, an activator of PERK/ATF4 signaling pathway, for 24 hours. At the end of culture, cell proliferation was detected by cell counting kit-8 assay, apoptosis was detected by flow cytometry, and mRNA and protein expressions of apoptosis-related proteins and PERK/ATF4 signaling pathway-related proteins were detected. RESULTS AND CONCLUSION: (1) Compared with the control group, the model group showed increased apoptosis (P < 0.05), decreased proliferative activity (P < 0.05), increased level of chondroglycoprotein 39 (P < 0.05), decreased level of type II collagen (P < 0.05), decreased mRNA and protein expression of Bcl-2 protein (P < 0.05), increased mRNA and protein expression of Bax protein, increased caspase-3 mRNA expression, increased Cleaved-caspase-3 protein expression (P < 0.05), increased mRNA expression of PERK, ATF4, and C/EBP homologous protein (P < 0.05), and increased protein expression of p-PERK, ATF4, and C/EBP homologous protein (P < 0.05). Compared with the model group, neferine reversed the above effects of interleukin-1β on chondrocytes in a concentration-dependent manner. (2) Compared with the drug group, the activator group showed increased apoptosis (P < 0.05), decreased proliferative activity (P < 0.05), elevated mRNA expression of caspase-3, ATF4, and C/EBP homologous protein (P < 0.05), and elevated protein expression of Cleavedcaspase-3, ATF4, and C/EBP homologous protein (P < 0.05). (3) To conclude, neferine inhibits interleukin-1β-induced chondrocyte apoptosis and enhances cell proliferation activity, and the mechanism of action may be related to blocking the PERK/ATF4 signaling pathway in the endoplasmic reticulum.

[Objective] To explore the changes of warming and humidification climate in the arid areas of northwest China since 1980s. [Method] Using the monthly temperature and precipitation from a 0. 5°× 0. 5° gridded datasets during 1981-2019 released by the National Meteorological Information Center, the spatiotemporal evolution characteristics of temperature and precipitation in the region over the past 39 years were studied using linear propensity rate, Mann-Kendall test and cumulative anomaly method. [Result] The temperature in the arid region of northwest had been increasing at a rate of 0. 377 ℃ / 10 a(P<0. 01) over the past 39 years, with the largest warming trend in the Tianshan subregion. The average temperature of all seasons showed a significant increasing trend, with the largest warming trend in spring. The warming trend in winter was the smallest, with a rate of only 0. 121 ℃ / 10 a(P>0. 05). The mean annual temperature had an abrupt change in 1997, and the warming trend slowed down in the 21st century. The annual precipitation in the northwest arid region showed an increasing trend with a rate of 9. 509 mm/ 10a(P<0. 01), and the Tianshan subregion showed the largest increasing trend with 25. 673 mm/ 10a (P<0. 01). The precipitation trend increased in all seasons, with the greatest increase in summer and relatively small increase in winter; the annual precipitation had an abrupt change in 2001, followed by a significant trend of increasing precipitation. [Conclusion] The arid region of northwest China is in the warm and humid stage, especially in the Tianshan subregion. [ABSTRACT FROM AUTHOR]

Poisoning cases of sika deer (Cervus nippon) due to grazing organophosphorus pesticide-contami-nated pasture occur frequently in the wild and in nature reserves. Acute organophosphate poisoning is characterized by symptoms such as parasympathetic excitement, diarrhea, salivation, and muscle tremors, which can lead to death in severe cases. Sika deer often die suddenly because of untimely treatment, and the disease often occurs in groups, which seriously affects the health and protection of sika deer. This article reports a case of acute organophosphorus poisoning in sika deer in a wildlife protection base of Heilongjiang Province. Through medical history investigation, clinical examination, case autopsy, field investigation and laboratory examination, it was diagnosed as organophosphorus poisoning caused by pesticidecontaminated pasture. For the deer herd, multiple diagnosis and treatment measures are taken to eliminate the source of toxins in the base to prevent ingestion, restrict breeding, detoxify the symptoms, increase the body's immunity, and put forward targeted preventive measures. We successfully controlled the mass poisoning of sika deer in the wildlife protection base, and provide reference for the treatment and prevention of such poisoning cases in the wildlife protection area.

The number of cotton seedlings can greatly contribute to the key seedling information, such as sowing survival rate and emergence rate. In this study, a cotton seedling counting algorithm was proposed using feature fusion. Five modules consisted of VGG basic, attention, feature fusion, and deredundancy normalization module. Among them, the VGG basic module was used the first four convolution layers of VGG-16, further removing the fifth convolution layer of VGG-16 and the subsequent pooling layer and full connection layer, in order to reduce the amount of calculation and model complexity. CBAM module included the Channel Attention Module (CAM) and Spatial Attention Module (SAM) to realize dual attention on the channel and spatial dimensions of features. The feature fusion module was used to fuse the features enhanced by the attention module and the first three layers of features extracted by the VGG basic module in three stages, thereby speeding up the learning speed of the model. Finally, the redundant information of the fused feature map was cleaned by the operation of deredundancy. The local counts of the single-channel feature map were redistributed by the operation of normalization. The algorithm flow was as follows. Firstly, the input image was used to generate a feature map through the VGG basic module. Then, the attention module was utilized to enhance the global information of the feature image through the channel and spatial dimensions. The feature fusion module was to fuse the enhanced features with the features in the basic module, and finally output the counting data after the removal of the redundant information and normalization. In addition, the field cotton seedling images were collected from 2017 to 2018. A new Cotton Seedling Counting dataset (CSC) was established using the images. A total of 212 572 seedlings were accurately and manually labeled in the dataset. Several typical target counting methods were compared on the CSC dataset, including MCNN, CSRNet, TasselNet, and MobileCount. Experiments showed that the Mean Absolute Error (MAE) and Root Mean Square Error (RMSE) of the counting were 63.46 and 81.33, respectively, indicating the lowest errors than that of the above four methods, while the average error decreased by 48.8% and 45.3%, respectively, indicating the effectiveness of the counting algorithm. Moreover, the test set was divided into two groups, where the midday group performed better in the light conditions, totaling 52 images. The morning and evening groups presented relatively weak light conditions, with a total of 47. Although photographed in different time periods and different light conditions, the performance of the model remained constant in the strong robustness and stability. when estimating the number of cotton seedlings in the actual cotton seedling images, the counting was still accurately estimated the number of seedlings under the interference of strong shadow noise, indicating the strong robustness. In addition, the Dropout feature fusion, attention module CBAM and normalization operation were verified by ablation experiments, indicating a positive impact on the model. Finally, image-based seedling counting can be widely expected to realize the scientific management of farmland. Anyway, the algorithm can be further optimized to explore the possibility of deploying on the real platform [ABSTRACT FROM AUTHOR]

The severe occlusion and scale variation in the cotton field reduce the accuracy of the object counting algorithm greatly. To solve above problems, this paper presented a cotton boll counting algorithm based on context multi-scale fusion. This algorithm consisted of the context module of the pyramid structure and the fusion convolutional neural network. Firstly, it adopted global context and local context modules to encode the context information in the cotton images, and then used multicolumn feature conversion module to map the input image into high-dimensional feature . Finally, it combined the context information with the high-dimensional feature through the fusion convolutional neural network, for achieving high-precision cotton boll counting and generating high-quality cotton boll density map. In addition, this paper conducted experiments on the cotton boll dataset from two angles of close-range and ground-air observation. The comparative experimental results show that adopting context information can effectively improve the accuracy of cotton boll counting, and the counting errors MAE and MSE have decreased by 27 . 3 and 29 . 4, respectively.
