Objective: To explore a simple and feasible method for the isolation and purification of hepatocytes, hepatic stellate cells (HSC), and lymphocytes from mice. Methods: The cell suspension was obtained from male C57bl/6 mice by hepatic perfusion through the portal vein digestion method and then isolated and purified by discontinuous Percoll gradient centrifugation. Trypan blue exclusion was used to determine cell viability. Glycogen staining, cytokeratin 18, and transmission electron microscopy were used to identify hepatic cells. Immunofluorescence was used to detect α-smooth muscle actin combined with desmin in HSCs. Flow cytometry was used to analyze lymphocyte subsets in the liver. Results: After isolation and purification, about 2.7×10(7) hepatocytes, 5.7×10(5) HSCS, and 4.6×106 hepatic mononuclear cells were obtained from the liver of mice with a body weight of about 22g. The cell survival rate in each group was > 95%. Hepatocytes were apparent in glycogen deposited purple-red granules and cytokeratin 18. Electron microscopy showed that there were abundant organelles in hepatocytes and tight junctions between cells. HSC had expressed α-smooth muscle actin and desmin. Flow cytometry showed hepatic mononuclear cells, including lymphocyte subsets such as CD4, CD8, NKs, and NKTs. Conclusion: The hepatic perfusion through the portal vein digestion method can isolate multiple primary cells from the liver of mice at once and has the features of simplicity and efficiency.

OBJECTIVE: To evaluate the risk factors affecting thromboembolism in lymphoma patients with chemotherapy. METHODS: Three hundred and four consecutive lymphoma patients treated by chemotherapy between January 2012 and July 2019 were enrolled and retrospectively analyzed, consisting of 111 patients with thromboembolism and 193 without thromboembolism. Univariate analysis was used to compare the clinical characteristics and related laboratory examination between the patients, while multivariate Logistic regression analysis were used to identify the risk factors affecting thromboembolism in lymphoma patients with chemotherapy. RESULTS: Univariate analysis showed that the female, BMI <18.5 or >24, ≥60 years old, with abnormal platelets before chemotherapy, prolonged single hospitalization days and patients at Ann Arbor stage III and IV could increase the incidence of thromboembolism in lymphoma patients treated by chemotherapy. Multivariate Logistic regression analysis showed that abnormal platelet count before chemotherapy, patients at Ann Arbor stage III and IV, and female were all the independent risk factors affecting thromboembolism in lymphoma patients thromboembolism after chemotherapy (P<0.05). CONCLUSION For lymphoma chemotherapy patients, female, abnormal platelet count before chemotherapy and Ann Arbor stages III and IV show a significantly higher risk for thromboembolism. Thus, preventive anticoagulation therapy is recommended.

Characterization of the polysaccharides and monosaccharides of Bupleurum chinense was undertaken to identify differences in the Bupleurum chinense's sugar profiles, so as to provide a basis for the identification of different varieties. High performance liquid chromatography (HPLC) was used to generate chromatograms of the total polysaccharides of Bupleurum using an Evaporation Light Detector (ELSD), and a monosaccharide chromatogram was generated using a UV-detector (UV) following polysaccharide derivatization. The data were analyzed using SIMCA software and SPSS software to distinguish different varieties of Bupleurum. The results show that the yield of polysaccharides from Bupleurum falcatum is the highest, while the yield of polysaccharides from Bupleurum chinense is the lowest. The polysaccharide spectrum shows that the molecular weights of the polysaccharides in different Bupleurum differ, and their percentages of the total peak area are also different. The four Bupleurum polysaccharides are composed of mannose, glucuronic acid, rhamnose, galacturonic acid, glucose, galactose, and arabinose, but differ in length. The ratio of glucose to arabinose in Bupleurum chinense, Bupleurum scorzonerifolium, Bupleurum falcatum and Bupleurum marginatum var. stenophyllum is: 3.0-4.0, 5.5-7.0, 12.0-17.0, 9.0-12.0. In this study, a sugar profile technique was developed to provide a new method for the identification of different varieties of Bupleurum.
