Abstract: Objective To predict the potential distribution of talaromycosis marneffei (TSM) and analyze its driving factors, so as to provide evidence for the surveillance and prevention of this disease. Methods The data of all laboratory-confirmed, non-duplicating TSM published in the English and Chinese literature from the first case in January 1964 to December 2018 was collected. A Maxent ecology model using environmental variables, Rhizomys distribution and HIV/AIDS epidemic was developed to forecast ecological niche of TSM worldwide, as well as identify the driving factors. Results A total of 705 articles (477 in Chinese and 228 in English) were obtained during the study period. After excluding imported cases, a total of 100 foci information were included in the model. The area under the receiver operating characteristic (ROC) curve (AUC) of the model was 0.997 for the training set and 0.991 for the test set. Maxent model revealed that Rhizomys distribution, mean temperature of warmest quarter, precipitation of wettest month, HIV/AIDS epidemic and mean temperature of driest quarter were the top 5 important variables affecting TSM distribution. In addition to identifying traditional TSM endemic areas (South of the Yangtze River in China, Southeast Asian, North and Northeast India), other potential endemic areas were also identified, including parts of the North of the Yangtze River, Central America, West Coast of Africa, East Coast of South America, the Korean Peninsula and Japan. Conclusion Our finding has discovered hidden high-risk areas and provided insights about driving factors of TSM distribution, which will help inform surveillance strategies and improve the effectiveness of public health interventions against TM infections.

Carbon dioxide peaking and carbon neutrality have become hot issues of political and economic activities in China and abroad. The structure and development of various industries in China will be profoundly affected in the process of accomplishing "Dual Carbon" goals. Eco-agriculture of Chinese medicine(EACM) highlights the balance and sustainable development of the ecosystem while producing high-quality medicinal materials. With chemically synthesized fertilizers, pesticides, and growth regulators prohibited, EACM emphasizes the recycling of agricultural and sideline products and the reduction of waste output, which results in the minimal negative impact on the ecological environment. Therefore, it is typical agriculture with low-carbon sources and high-carbon sinks. This study reviewed the mechanism and potential of EACM in carbon dioxide peaking and carbon neutrality, analyzed the specific ways of EACM in reducing carbon sources and increasing carbon sinks based on the typical ecological planting pattern, and proposed the point of view to strengthen EACM as well as the "Dual Carbon" theory and research methods, so as to direct low-carbon and efficient deve-lopment. Furthermore, this study advocated to comprehensively promote the transformation of Chinese medicine production from chemical agriculture to eco-agriculture to improve the comprehensive benefits of contribution rate of carbon neutrality, explore and establish carbon sink compensation mechanism to ensure the sustainable and healthy development of EACM, and strengthen the training of EACM and "Dual Carbon" theory and technologies to continuously improve the capacity of EACM in sustainable development. This study is expected to provide a reference for the development of ecological functions in EACM and the development of economic functions through ecological functions.

Green agriculture has become the "wind vane" of agricultural reform in the new era. The development concept of Chinese materia medica(CMM) ecological agriculture and the emergence of new technologies provide momentum for the supply of high-quality green ecological products. As special ecological products, Dao-di herbs have medicinal, economic, ecological, and cultural values. The ecological planting of CMM and the value realization of ecological products are of great significance for the high-quality development of CMM agriculture and for prospering agriculture by improving quality. Therefore, this paper reviews the development status and typical cases, and puts forward the advantages of ecological product value realization of Dao-di herbs. On this basis, a value accounting system for ecological products of CMM was constructed from three aspects: supply services, ecological services, and cultural services. Finally, the suggestions for realizing the value of CMM ecological products are put forward.(1)It is suggested to strengthen the practice of ecological planting and production of CMM, and innovate the value realization model of ecological products.(2)The ecological planting bases of Dao-di herbs should be constructed to enhance the supply capacity of high-quality ecological products.(3)The quality and safety of ecological CMM should be improved to create the ecological planting brand of Dao-di herbs.(4)The ecological product value system and mechanism should be improved for realizing the value of CMM ecological products.(5)The education and publicity should be strengthened to raise the public awareness of the value of CMM ecological products.

Good agricultural practices(GAP) for Chinese herbal medicine(CHM) is the source of quality control in the production of CHM. To ensure the safety, efficacy, and quality of Chinese herbal and natural medicine, the international community has been exploring the implementation of GAP for CHM. The implementation of GAP for CHM has a far-reaching impact, and the scale planting of CHM has been expanding. However, the medicinal materials produced by the GAP bases for CHM still cannot fully meet the market demand, and the output and quality of CHM remain to be improved. This paper summarizes construction status of GAP bases for CHM.The 129 companies that passed the certification during the implementation of GAP for CHM included 196 GAP bases, forming the scale CHM production zone with Sichuan province, Yunnan province, Jilin province, Henan province, and Shandong province as the core.The total area of GAP bases for CHM in China is about 250 000-500 000 Mu(1 Mu≈667 m2), which is still less than 1% of the total production area of CHM. The international agricultural production quality management strategies are all market-oriented behaviors.Drawing on the international good agricultural and collection practice(GACP) and hazard analysis critical control point(HACCP) as well as the relevant policies of Chinese quality management of CHM, we put forward feasible suggestions for the further implementation of GAP for CHM:(1)The market rules and international experience should be followed and employed to promote GAP management of CHM and third-party implementation of GAP certification;(2)The sound development of GAP for CHM should be boosted with the HACCP management system and the revision of GAP for CHM;(3)The implementation of policies and standards should be stepped up to facilitate the building of a whole-course traceability system for the production of CHM with high quality and reasonable prices.

Objective: To analyze the prognostic value of CD7 expression in newly diagnosed acute myeloid leukemia (AML) patients, and to further explore the correlation between CD7 expression and CEBPA mutation, and to clarify the prognostic value of CD7(+) in AML patients with wild-type (WT) or mutant-type (MT) CEBPA. Methods: The clinical data of 298 newly diagnosed non-M(3) AML patients between January 2010 and December 2016 were analyzed retrospectively. The clinical characteristics and prognosis of CD7(+) and CD7(-) patients were respectively compared in all patients, and in patients with WT and MT CEBPA. The relationship between CD7 expression and CEBPA mutation was determined by chi-square, and the effects of CEBPA mutation on survival and prognosis in CD7(+) group by Kaplan-Meier method. Results: In CD7(+) group, the frequencies of CEBPA mutation were 10.1% (single site) and 33.9% (double site) , significantly higher than those of the CD7(-) group (5.3% and 4.2%) (P=0.000) . Subgroup prognostic analysis showed a lower CR rate (P=0.001) and a higher RR (P=0.023) in CD7(+) group comparing to those of CD7(-) group in AML patients with wild type CEBPA. There were no statistical difference between CD7(+) group and CD7(-) group in overall survival (OS) and disease free survival (P>0.05) , while in the CEBPA mutant group the CD7(+) group has higher OS (P=0.019) and DFS (P=0.010) . Based on the CD7 expression and CEBPA mutation, 298 cases were divided into 3 subgroups, named as CD7(+)-CEBPA MT group, CD7(-) and CD7(+)-CEBPA WT group. The 3-year OS of the 3 groups were 80.2%, 48.0% and 30.6%, respectively (P<0.001) , and the 3-year DFS were 74.1%, 37.4% and 22.2%, respectively (P<0.001) . Conclusion: The CEBPA mutation rate was higher in CD7(+) AML patients then that of CD7(-) patients. CD7 expression has opposite prognostic significance in AML patients carrying the wild-type or mutant-type CEBPA. Based on CD7 expression and CEBPA mutation, a new risk stratification model can be established, which is helpful to guide the clinical individualized treatment for AML patients.

【Objective】 To summarize the CT and MRI imaging features of gallbladder neuroendocrine tumor.【Methods】 CT and MRI data of 10 patients with gallbladder neuroendocrine tumors proven by surgical pathology between January 2010 and May 2018 were retrospectively analyzed. Among them,6 patients underwent CT examination,3 underwent MRI examination,and 1 patient underwent both CT and MRI examinations. The size,morphologic features and contrast enhancement pattern of gallbladder tumors,and the presence of liver metastasis,bile duct and perihepatic metastasis,lymph node metastasis,and the presence of gallbladder stone were assessed.【Results】Among these 10 cases of gallbladder neuroendocrine tumor,the largest dimension of tumors ranged from 39 mm to 120 mm. The tumors manifest? ed as a mass protruding into the lumen with a broad base adhering to the wall of the gallbladder. In 7 patients who had undergone CT examination,the tumors manifested as an irregular mass with soft tissue density on CT. In 4 patients who had undergone MRI,the tumors showed homogeneous iso-intense signal on T1-weightedimaging,heterogenous hyper-intense signal on T2- weighted imaging,and limited diffusion on diffusion- weighted imaging. All tumors in 10 patients showed moderate,heterogeneous and persistent enhancement. Eight patients had liver metastasis,among whom 7 had metastases in liver segments 4 and 5,and 1 had multiple metastases in other liver segments. Six patients had bile duct invasion and 3 had hilar fat invasion. Seven patients had lymph node metastasis. One patient had gallstone.【Conclusion】Gallbladder neuroendocrine tumor has certain characteristic CT and MRI findings,such as a large mass in gallbladder,which tends to invade adjacent liver parenchyma,and extend along gallbladder neck and gallbladder ducts,accompanied with hepatic portal and retroperitoneal lymph node metastasis,and hilar fat invasion.

Herb residue is post-decoction material that can be used as organic fertilizer. Unfortunately, it is currently disposed of as solid waste. This method of disposal is a waste of this resource and a source of environmental pollution. For this case,we studied effects of six different herb residues compost on growth and phenols of Perilla frutescens by pot experiment. Our results show that all six herb residues can improve the growth of P. frutescens. The order of their efficiencies was as follows: Salviae Miltiorrhizae Radix residue>Hordei Fructus germinates residue>Forsythia fructus residue>Atractylodis Macrocephalae Rhizome residue>Sophorae Flavescentis Redix residue and Moutan cortex residue. Effects of Sophorae Flavescentis Radix residue and Moutan Cortex residue weren't significantly different from CK. Six herb residue all improve root system architecture and leaf area. To phenols of P. frutescens, six herb residues all increased the rosmarinic acid and caffeic acid content of root, and accumulation of four phenols. All the analysis showed herb residues compost can improve the growth and four phenols accumulation of P. frutescens, and Salviae Miltiorrhizae Radix residue had the most pronounced effect on P. frutescens.
