To clarify the species, pathogenicity, and distribution of the pathogens causing the root rot of Atractylodes lancea in Hubei province, the tissue separation method was used to isolate the pathogens from root rot samples in the main planting areas of A. lancea in Hubei. Based on the preliminary identification of the Fusarium genus by the internal transcribed spacer(ITS) sequence, three housekeeping genes, EF1/EF2, Btu-F-FO1/Btu-F-RO1, and FF1/FR1, were amplified and sequenced. Subsequently, a phylogenetic tree was constructed based on these TEF gene sequences to classify the pathogens. The pathogenicity of these strains was determined using the root irrigation method. A total of 194 pathogen strains were isolated using the tissue separation method. Molecular identification using the three housekeeping genes identified the pathogens as F. solani, F. oxysporum, F. commune, F. equiseti, F. tricinctum, F. redolens, F. fujikuroi, F. avenaceum, F. acuminatum, and F. incarnatum. Among them, F. solani and F. oxysporum were the dominant strains, widely distributed in multiple regions, with F. solani accounting for approximately 54% of the total isolated strains and F. oxysporum accounting for approximately 34%. Other strains accounted for a relatively small proportion, totaling approximately 12%. The results of pathogenicity determination showed that there were certain differences in pathogenicity among strains. The analysis of the pathogenicity differentiation of the widely distributed F. solani and F. oxysporum strains revealed that these dominant strains in Hubei were mainly highly pathogenic. This study determined the species, pathogenicity, and distribution of the pathogens causing the root rot of A. lancea in Hubei province. The results provide a scientific basis for further understanding the root rot of A. lancea and its epidemic occurrence and scientifically preventing and controlling this disease.

Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.

Artemisia argyi is a perennial herbaceous herb of the Artemisia family, with leaves for medical use. However, the germplasm of A. argyi is seriously unclear and mixed during production, and it is urgent to protect new varieties of A. argyi. The distinctness, uniformity, and stability(DUS) testing of the new varieties of plants is the basis for the protection of new varieties of plants, and the development of the DUS testing guidelines is the technical basis for DUS testing. To develop the DUS testing guidelines of A. argyi, A. argyi of 100 germplasm was used as the research objects, and their agronomic and medicinal quality characters were observed and measured during six growth stages, and each character was graded and described. A total of 53 test characters were determined, including 19 characters that must be tested; there were four plant characters, two rhizome characters, five stem characters, three branching characters, 29 leaf characters, three floral characters, five medicinal quality characters, and two other characters. It also involved 16 quality characters, 22 quantitative characters, and 15 pseudo-quantitative characters. Seven grouping characters were determined from 53 characters, including "emergence period" "plant-plant type" "branching-primary branching site" "stem-color" "middle leaf-number of leaf splits" "budding period", and "plant-height". By searching for standard characters, 16 standard varieties were ultimately determined. The preparation of this guideline was of great significance for the review and protection of new A. argyi varieties, the protection of breeders' rights, and the promotion of the development of A. argyi industry.

In terms of treatment, 33 patients received immunotherapy on the basis of symptomatic treatment, and 13 of them showed improvement in clinical symptoms. Conclusions:The clinical manifestations of AE patients are highly heterogeneous, with typical initial clinical manifestations including mental abnormalities, epileptic seizures, cognitive and motor disorders. Neuroimaging changes are mainly in the temporal lobe or hippocampus, and antibody detection can timely confirm the diagnosis of AE. Early immunotherapy is the key to improving the prognosis of AE.

Objective:To analyze the clinical and laboratory characteristics of acute myeloid leukemia (AML) patients with NPM1 mutation, and to explore the prognostic factors.Methods:A total of 77 AML patients with NPM1 gene mutation admitted to Hebei Yanda Ludaopei Hospital from May 1st 2012 to December 31st 2021 were enrolled in the study, including 34 male and 43 female patients. The median age was 40 (3, 68) years old. Patients were selected and divided into 4 groups according to the morphological FAB classification. There were 29 cases (37.7%) of M1 type, 13 cases (16.9%) of M2 type, 23 cases (29.9%) of M4 type, and 12 cases (15.5%) of M5 type. The clinical characteristics, bone marrow/peripheral blood cell morphology, immunophenotype, cytogenetics, molecular biology and overall survival of different groups were retrospectively analyzed, and the risk factors affecting the prognosis of AML were also explored. Cox multivariate regression was used to analyze the clinical influencing factors of survival and prognosis.Results:The white blood cell counts were highest in M4 and M5 patients and lowest in M2 patients, while no significant difference in the red blood cell, hemoglobin, and platelet counts( P>0.05). Morphologically, there were significant differences in the percentage of blasts and blasts with cup-like nuclei on bone marrow (BM) and peripheral blood (PB). The proportion of blasts in BM and PB was the highest in M1 and the lowest in M2 ( P<0.001). The positive rate of blasts with cup-like nuclei was the highest in M1 and the lowest in M5 of BM ( P<0.001), while the highest in M2 and the lowest in M5 of PB ( P=0.006). The scores of myeloperoxidase and chloroacetate esterase were all the highest in M1 and the lowest in M5 ( P<0.001, 0.001, respectively). In terms of molecular biology, the occurence rate of blasts combined with DNMT3A mutation was the highest in M4 and the lowest in M2 ( P=0.044), while those combined with FLT3-ITD mutation was the highest in M4 and the lowest in M5 ( P=0.002). In immunophenotype, there were significant differences in the expression positivities of seven antigens including HLA-DR, CD56, CD11c, CD15, CD14, CD96 and cMPO ( P<0.05). Multivariate COX regression analysis showed that no recurrence after treatment ( P<0.001), complete remission after treatment ( P=0.015) and transplantation ( P<0.001) were correlated with overall survival (OS). No recurrence after treatment ( P=0.033), transplantation ( P=0.027), no mutation of FLT3-ITD ( P=0.040), and hemoglobin concentration ( P=0.023) were associated with relapse-free survival (RFS). Survival analysis by Kaplan-Meier curve showed that there was no significant difference in survival time between the M1, M2, M4 and M5 groups in OS and RFS. Conclusion:There were significant differences in the white blood count, the percentage of blasts and blasts with cup-like nuclear morphology, cytochemical staining (MPO integration, CE integration and percentage of NAS-DCE), gene mutation (DNMT3A and FLT3-ITD) and immunophenotypes (HLA-DR, CD56, CD11c, CD15, CD14, CD96 and cMPO) between the four groups. The multivariate analysis revealed that no recurrence after treatment and transplantation were independent prognostic factors in NPM1 mut AML patients. On the other hand, FLT3-ITD mutation and hemoglobin concentration were associated with RFS and complete remission after treatment was associated with OS in the entire NPM1 mut cohort.

Objective: To investigate the distribution of blood pressure and analyze the associated factors of blood pressure of the elderly with type 2 diabetes in Jiangsu Province. Methods: The elderly over 60 years old participants with type 2 diabetes in the communities of Huai'an City and Changshu City, Jiangsu Province were selected in this study. They were divided into two groups: taking antihypertensive drugs and not taking antihypertensive drugs. The demographic characteristics, such as age and sex, and relevant factors were collected by questionnaire. The systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by physical examination. The percentile of SBP and DBP in each age group of men and women were described. The kernel density estimation curve was used to show the blood pressure distribution. The trend of blood pressure with age was fitted by locally weighted regression. The logistic regression model was used to analyze relevant factors of blood pressure. Results: A total of 12 949 participants were included in this study, including 7 775 patients in the antihypertensive drug group and 5 174 patients in the group without antihypertensive drugs. The SBP of participants was concentrated at 140-160 mmHg, and their DBP was concentrated at 75-85 mmHg. There were significant differences in the distribution of blood pressure among the subgroups of body mass index (BMI) and rural areas whether taking antihypertensive drugs and not. For participants aged under 80 years old, the SBP showed an increasing trend with age and the DBP showed a decreasing trend with age. Age, BMI ≥24 kg/m², fasting blood glucose ≥7.0 mmol/L, living in rural areas and no smoking were influencing factors of the elevated SBP; BMI ≥24 kg/m², male, living in rural areas, no smoking, drinking alcohol and not receiving drug hypoglycemic treatment were influencing factors of the elevated DBP. Conclusion: The SBP of older diabetic adults in Jiangsu Province is at a high level, and the distribution of blood pressure is significantly different between men and women in taking antihypertensive drugs group. The SBP presents a rising trend and the DBP is decreasing at the age of 60-80 years. The blood pressure level of this population are mainly affected by age, BMI, urban and rural areas, smoking.
