ObjectiveTo analyze and assess the pollution levels of lead (Pb), cadmium (Cd), and chromium (Cr) in rural soils of Wanzhou District, Chongqing Municipality, and to provide data support for proposing relevant measures and suggestions. MethodsBased on the soil monitoring data from 2017 to 2021, the ecological risk assessment was conducted by applying the Soil Pollution Risk Control Standard for Agricultural Land of Soil Environmental Quality (for trial implementation) (GB 15168‒2018), the pollution index method and the potential ecological risk method. ResultsA total of 100 soil samples were collected, with pH values ranged from 3.50 to 8.30, and a mean value of 6.10. The mean values of Pb, Cd, and Cr in the soil were 25.2 mg·kg-1, 0.310 mg·kg-1, and 68.6 mg·kg-1, respectively. Except for Cr, the mean values of other elements exceeded the soil background values. Cd level had the largest coefficient of variation and uneven spatial distribution, with an overall exceedance rate of 30.0%. Pollution levels of Pb and Cr were generally at the alert level, while Cd was generally at a light pollution level. The proportion of Cd pollution levels was higher than that of Pb and Cr, and the difference was statistically significant(χ2=15.015, P=0.001). The Nemerow comprehensive pollution index in different townships ranged from 0.70 to 2.07, with a median value of 1.10, and was generally at a light pollution level. The potential ecological hazard risk of Cd was relatively high, and was generally at a mild level of hazard. The highest contribution rate in the comprehensive potential ecological hazard index was Cd, accounting for 84.1%. ConclusionThere is a certain degree of Cd pollution and mild ecological risk in rural soils of Wanzhou District. Monitoring and management of Cd pollution in rural soils of Wanzhou District, Chongqing Municipality, should be strengthened.

Medicinal plants are beneficial to human health. However,most of the major producing regions of medicinal plants suffer from rust disease,which threatens the yield and quality of Chinese medicinal materials,thus causes huge economic loss,and hinders the sustainable development of the Chinese medicine industry. By the end of 2020,rust disease had been reported in medicinal plants of 76 species and 33 families. In the 76 species,79 rust pathogens were detected. The majority of these pathogens belonged to Puccinia( 33,39. 24%),Coleosporium( 14,15. 19%),and Aecidium( 11,13. 92%). Of these 79 rust pathogens,10 were autoecious and 13 were heteroecious. Through literature research,this study reviewed the symptoms,pathogen species,severity and distribution,prevalence and occurrence conditions,and control measures of rust disease in medicinal plants,and thereby summarized the research status of rust disease in medicinal plants and the gap with other plants,which is expected to serve as a reference for further research on rust disease in medicinal plants.

Bupleuri Radix is a traditional Chinese medicine commonly used in clinical practice, which has the effects of relieving fever, relieving liver and depression, and promoting Yangqi. At present, the varieties of Bupleuri Radix are relatively chaotic, and the processing in the production areas is relatively extensive. In the processing of Bupleuri Radix, the processed products contained in the 2015 edition of Chinese Pharmacopoeia are raw products and vinegar-processed products. In addition, the specifications on Chinese medicine processing in various provinces and cities contain many processing methods, such as stir-frying with wine, stir-frying with honey, processed with turtle blood, etc. However, there are great differences in processing specifications among provinces and cities, and the processing methods lack clear process parameters, so the quality of Bupleuri Radix decoction pieces produced on these basis is uneven, which affects the clinical application of the decoction pieces. By consulting ancient books and relevant literature, the authors conduct textual research on the varieties of Bupleuri Radix, and systematically summarized the processing methods and processing methods in the producing area, so as to provide reference for the establishment of processing technology specifications and quality standards of Bupleuri Radix decoction pieces.

Interferon-γ (IFN-γ) has been used to control cancers in clinical treatment. However, an increasing number of reports have suggested that in some cases effectiveness declines after a long treatment period, the reason being unclear. We have reported previously that long-term IFN-γ treatment induces malignant transformation of healthy lactating bovine mammary epithelial cells (BMECs) in vitro. In this study, we investigated the mechanisms underlying the malignant proliferation of BMECs under IFN-γ treatment. The primary BMECs used in this study were stimulated by IFN-γ (10 ng/mL) for a long term to promote malignancy. We observed that IFN-γ could promote malignant cell proliferation, increase the expression of cyclin D1/cyclin-dependent kinase 4 (CDK4), decrease the expression of p21, and upregulate the expression of cellular-abelsongene (c-Abl) and histone deacetylase 2 (HDAC2). The HDAC2 inhibitor, valproate (VPA) and the c-Abl inhibitor, imatinib, lowered the expression level of cyclin D1/CDK4, and increased the expression level of p21, leading to an inhibitory effect on IFN-γ-induced malignant cell growth. When c-Abl was downregulated, the HDAC2 level was also decreased by promoted proteasome degradation. These data suggest that IFN-γ promotes the growth of malignant BMECs through the c-Abl/HDAC2 signaling pathway. Our findings suggest that long-term application of IFN-γ may be closely associated with the promotion of cell growth and even the carcinogenesis of breast cancer.
