This paper systematically combed and verified the name， origin， producing area， quality evaluation， harvesting， processing of Euryales Semen in famous classical formulas by consulting relevant ancient materia medica， medical books， prescription books and modern literature. The results showed that Euryales Semen was first collected by materia medica under the name of Jitoushi， and since the Ming dynasty， Qianshi has been used as a proper name and continues to this day， with other aliases such as Yanhuishi. Euryale ferox， a plant of the Nymphaeaceae family， is the same as that used in the past dynasties. However， due to long-term artificial domestication， the varieties vary with the origin， including Beiqian and Suqian. The medicinal part of Euryales Semen is mature seed kernel， its origin of ancient records mainly includes Shandong， Jiangsu， Henan and other places， since the Ming and Qing dynasties， Euryales Semen produced in Suzhou has been highly praised. Since modern times， it has gradually summarized and formed the best quality evaluation method of Euryales Semen with full grains， white cross-section， powdery enough and no broken powder. The harvesting time in the past dynasties was mainly August or in autumn. The main processing methods in the past dynasties included peeling for powder， pounding powder after steaming， drying and frying. Up to now， two mainstream processing methods of cleansing and stir-frying have been formed. Based on the research results， it is recommended that the mature seed kernel of E. ferox be used in famous classical formula Yihuangtang. Combined with the processing requirements of the original formula， it is suggested to refer to the stir-frying method in the general principles of processing of the current edition of Chinese Pharmacopoeia.

The purpose of this study was to investigate the intervention effect and mechanism of Lycium barbarum leaves on letrozole-induced polycystic ovary syndrome (PCOS) mice. The PCOS model was prepared by letrozole combined with high-fat diet. After successful modeling, 40 mice were randomly divided into PCOS group, positive drug metformin group, low-dose Lycium barbarum leaves group, and high-dose Lycium barbarum leaves group. The corresponding drugs were given by gavage for 29 days. At the end of the experiment, the eyeballs were removed for blood collection and ovarian tissue was collected. The ovarian mass, fasting blood glucose (FBG), fasting insulin (FINS), testosterone (T), anti-Mullerian hormone (AMH), luteinizing hormone (LH), follicle stimulating hormone (FSH), and estradiol (E₂) levels were measured in each group. The morphology of ovarian tissue was observed by hematoxylin-eosin staining, and the oocytes, cystic follicles and corpus luteum were counted. Cecal contents of mice were collected for analysis of intestinal flora composition and differential flora. The animal experiment process was approved by the Animal Ethics Committee of Nanjing University of Traditional Chinese Medicine. The results showed that the estrous cycle of PCOS mice was disordered. Compared with the PCOS group, the Lycium barbarum leaves group can significantly reduce the ovarian damage of mice, reduce the number of cystic dilated follicles, and normalize the estrous cycle. After the intervention of Lycium barbarum leaves, the levels of FBG, FINS, T, AMH, LH, FSH and LH/FSH were significantly decreased (P < 0.05), while the level of E₂ was significantly increased (P < 0.001). In addition, Lycium barbarum leaves can regulate the disorder of intestinal flora diversity in PCOS mice, increase the abundance of Bacteroidetes, and reduce the abundance of Firmicutes, Ileibacterium, Romboutsia and Faecalibaculum. In summary, Lycium barbarum leaves can play a therapeutic role in PCOS mice by improving insulin resistance, regulating reproductive hormone disorders and gut microbiota imbalance. It provides scientific basis and useful reference for the rational utilization and development of Lycium barbarum leaves.

Given its state of stable proliferative inhibition, cellular senescence is primarily depicted as a critical mechanism by which organisms delay the progression of carcinogenesis. Cells undergoing senescence are often associated with the alteration of a series of specific features and functions, such as metabolic shifts, stemness induction, and microenvironment remodeling. However, recent research has revealed more complexity associated with senescence, including adverse effects on both physiological and pathological processes. How organisms evade these harmful consequences and survive has become an urgent research issue. Several therapeutic strategies targeting senescence, including senolytics, senomorphics, immunotherapy, and function restoration, have achieved initial success in certain scenarios. In this review, we describe in detail the characteristic changes associated with cellular senescence and summarize currently available countermeasures.

Juvenile zebrafish were used to screen the active components of Lycii Fructus for improving osteoporosis. The screening results were further verified by zebrafish adult osteoporosis model and the action mechanism was explored. Prednisolone was used as the inducer to build osteoporosis models of juvenile and adult zebrafish, and 9 groups of samples of different extracts and chemical parts of Lycii Fructus were given. Alizarin red staining was applied for observing the scale matrix mineralization and bone resorption. The activities of osteoblasts and osteoclasts were detected using alkaline phosphatase (ALP) and tartrate resistant acid phosphatase (TRAP/TRACP) staining. The expressions of bone metabolism-related genes alp, osteoprotectin (opn), osteoblast specific transcription factor (sp7), cathepsin K (ctsk), tracp, and Runt family transcription factor 2b (runx2b) in each group were determined using quantitative polymerase chain reaction. The results showed that all components of Lycii Fructus improved the formation area of the first vertebrae, the staining light density value, and the number of vertebrae joints in juvenile zebrafish and the Lycium barbarum polysaccharide (LBP) treatment group exerted the best effect. In addition, LBP prevented the formation of bone resorption lacunae in zebrafish scales, increased ALP activity, decreased TRAP activity, up-regulated the alp, sp7, and opn genes, and lowered the expressions of ctsk and tracp genes. In conclusion, LBP regulated the activity of osteoblasts and osteoclasts, reduced bone resorption, promoted bone formation and enhanced bone density, which might be the main anti-osteoporosis active fraction of Lycii Fructus. This study provided modern scientific evidence for the scientific connotation of the traditional effect of "strengthening bones and muscles" of Lycii Fructus, provided the reference for the evaluation of the anti-osteoporosis activity of traditional Chinese medicine based on zebrafish adult model, and provided beneficial enlightenment for the bone health needs of the aging society population.

Acute myeloid leukemia (AML) is a heterogeneous hematopoietic tumor originated from hematopoietic stem cells. FLT3 is an important receptor tyrosine kinase in cell signal transduction pathway and one of the common mutated genes in AML. AML patients with FLT3-ITD mutation have a poor prognosis and tendency to relapse. Therefore, early identification of FLT3 gene mutation and selection of appropriate treatment are particularly important. Currently, the small moleculetargeted drugs have been new treatment methods for AML patients with FLT3-ITD mutation, but accompanied drug resistance need to be solved. This paper reviews the mechanism of FLT3 mutation, the clinical significance of FLT3 mutation in AML, FLT3 inhibitors and drug resistance mechanism.

This study aimed to provide data support for resource utilization of the stems and leaves of Astragalus membranaceus var. mongholicus(SLAM) by analyzing and evaluating the chemical constituents. The crude protein, crude fiber, and soluble saccharide of SLAM were analyzed by Kjeldahl method, filtration method, and UV-Vis spectrophotometry, respectively. The nucleosides, amino acids, flavonoids, and saponins of SLAM were analyzed by ultraperformance liquid chromatography-triple quadrupole mass spectrometry(UPLC-TQ-MS). Combined with principal component analysis(PCA), the quality difference of resource components of SLAM was comprehensively evaluated. The results showed that the average content of crude protein, crude fiber, total polysaccharide, and redu-cing sugar in SLAM was 5.11%, 30.33%, 11.03 mg·g~(-1), and 31.90 mg·g~(-1), respectively. Six nucleosides, 15 amino acids, 22 flavonoids, and one saponin were detected, with an average content of 1.49 mg·g~(-1), 6.00 mg·g~(-1), 1.86 mg·g~(-1), and 35.67 μg·g~(-1), respectively. The content of various types of chemical components in SLAM differed greatly in different harvesting periods and growing years. The results of PCA showed that the quality of SLAM produced in Ningxia was superior. The results can provide references for the utilization of SLAM.

OBJECTIVE: To explore the value of multiple detection methods based on histopathology and supplemented by bone marrow or peripheral blood sample detections in the comprehensive diagnosis of mantle cell lymphoma (MCL). METHODS: The clinical, immunophenotypic, pathologic, cytogenetic and molecular features of 153 newly diagnosed MCL patients admitted to the hematology department of our hospital from May 2009 to September 2022 were analyzed. RESULTS: 144 (96.6%) of the 149 MCL patients who underwent marrow or peripheral blood IGH/CCND1 FISH detection at initial diagnosis were positive, of which 36 cases (24.2%) had a low proportion positive. The immunophenotypes in 115 patients were analyzed by flow cytometry (FCM), 89 cases (77.4%) conformed to MCL while 23 cases (20.0%) were initially diagnosed as B-cell lymphoproliferative disorders (B-LPD). Of the 75 cases who performed bone marrow biopsy, 50 cases (66.7%) had morphological and immunophenotypic characteristics consistent with MCL, 15 cases (20.0%) were classified as B-LPD, and 10 cases with no obvious abnormality. 77 patients underwent histopathology examination, of which 73 cases (94.8%) had typical clinicopathological features of MCL, including 2 CCND1 negative MCL, 2 pleomorphic variants, 5 pleomorphic variants and 4 cases diagnosed as other leukemia or lymphoma. Among 153 cases of MCL, 128 cases were classic MCL(cMCL), and another 25 cases (16.3%) were diagnosed as leukemic non-lymph node MCL (lnnMCL). The incidence of IGHV mutation, TP53 mutation and CD23 expression positive were significantly different between cMCL and lnnMCL. CONCLUSION Histopathology is still the main standard for the diagnosis of cMCL, and detection based on bone marrow or peripheral blood samples is an important means for the diagnosis of lnnMCL. Single marker or examination can cause a certain proportion of misdiagnosis. The accurate diagnosis of MCL depends on a combination of multiple detection methods.
