Clinical pharmacist participated in the whole process of combined drug treatment and medication monitoring of a patient with refractory edema secondary to end-stage diabetic kidney disease.By using dapagliflozin combined with sacubitril valsartan and conventional diuretics,the patient's body weight decreased by 16 kg,blood pressure returned to normal,systemic edema subsided and the symptoms of heart failure obviously improved.In this case,clinical pharmacist provided individualized pharmaceutical care and assisted clinicians to make a scientific and reasonable drug therapy,so as to provide a new idea and medication reference for clinical patients to delay the time of renal replacement therapy.

Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions. The professional guideline is required to guide the standardized and efficient clinical comprehensive evaluation of Chinese patent medicine and further improve the authority and quality of evaluation. In combination with the characteristics of Chinese patent medicine and the latest research achievement at home and abroad,the detailed specifications were formulated from six aspects including design,theme selection,content and index,outcome,application and appraisal,and quality control. The guideline was developed based on the guideline development requirements of China Assoication of Chinese medicine. After several rounds of expert consensus and public consultation,the current version of the guideline has been developed.

Sphingosine kinase (SphK), sphingosine-1-phosphate (S1P) and S1P receptor (S1PR) are involved in the tumor biological processes such as tumor cell proliferation and migration, and play an important role in the development of cancer. In recent years, researchers have increasingly focused on the interaction between cancer cells and the tumor microenvironment. The tumor microenvironment is genetically stable and can be induced to an antitumor phenotype, which has significant therapeutic advantages. Studies have shown that SphK/S1P/S1PR can regulate multiple aspects of the tumor microenvironment. This review summarizes the effects of SphK and S1P/S1PR signaling on the tumor microenvironment from four perspectives: tumor immune microenvironment, cancer associated fibroblasts, tumor angiogenesis and tumor hypoxic microenvironment, and also outlines potential drug research related to these signal molecules, aiming to elucidate the role of SphK/S1P/S1PR in tumor occurrence and development and provide new ideas for the research of anti-tumor drugs.

OBJECTIVE: Psoriasis is a common chronic inflammatory skin disease that is prone to recurrence, and the proinflammatory factor, cysteine-rich protein 61 (Cyr61), is important in its pathophysiology. Long-term clinical practice has shown that Sancao Formula (SC), a Chinese herbal compound, is effective in the treatment of psoriasis, but the precise mechanism remains unknown. In this study, we investigate the mechanism by which SC extract alleviates imiquimod (IMQ)-induced psoriasis. METHODS: The expression of Cyr61 in psoriatic lesions and normal healthy skin was detected using immunohistochemical analysis to investigate the biological role of Cyr61 in models of psoriatic inflammation. A psoriatic mouse model was established by topical application of IMQ, and the effect of topical application of SC extract was evaluated using the psoriasis area and severity index (PASI) score, hematoxylin-eosin staining, and histopathological features of the skin. Next, a HaCaT cell inflammation model was established using interferon-γ (IFN-γ), and the effect of SC extract on the mRNA and protein levels of Cyr61 and intercellular cell adhesion molecule-1 (ICAM-1) was confirmed using Western blot and quantitative real-time polymerase chain reaction analyses. RESULTS: Immunohistochemical staining showed that the expression of Cyr61 in psoriatic lesions was higher than that in normal skin samples (78.26% vs 41.18%, P < 0.05), and the number of Cyr61-positive cells in psoriatic lesions was also significantly higher than in normal skin (18.66 ± 2.51 vs 4.33 ± 1.52, P < 0.05). Treatment in mice with IMQ-induced psoriasis showed that SC extract could significantly improve the inflammatory phenotype, PASI score (10.875 ± 0.744 vs 3.875 ± 0.582, P < 0.05), and pathological features compared with those in IMQ model group; SC treatment was also associated with decreased levels of Cyr61 and ICAM-1. In the IFN-γ-induced inflammatory cell model, the mRNA and protein levels of Cyr61 and ICAM-1 were upregulated, while the SC extract downregulated the levels of Cyr61 and ICAM-1. CONCLUSION The results provide a theoretical basis for the involvement of Cyr61 in the pathogenesis of psoriasis, and suggest that SC should be used to target Cyr61 for the prevention of psoriasis recurrence.

Objective:To systematically investigate the chemical constituents of 90% ethanol extract of Corydalis impatiens，and evaluate their inhibitory effect on cell proliferation in vitro. Method:The chemical constituents were isolated and purified by silica gel，Sephadex LH-20，ODS column chromatography and semi-preparative high performance liquid chromatography （HPLC）.the structures were identified by spectroscopy methods such as NMR and MS，as well as analysis of physicochemical properties and/or comparison with literature data，and the inhibitory activities of 13 compounds on HepG2 and SMMC-7721 cells were measured by methyl thiazolyl tetrazolium （MTT） method. Result:Thirteen known compounds were isolated and identified from 90% ethanol extract of Corydalis impatiens as ethyl-5-hydroxy-2-pyridinecarboxylate（1），coryhumolide（2），3，4-cis-3，4-dihydroxy-β-ionone（3），megastigmane（4），9-hydroxy-4，7-megastigmadien-3-one（5），blumenol A（6），indole-3-carboxy acid（7），1-methyl-[1，2，4]triazolo[4，3-b][1，2，4]triazin-7-one （8），adenine（9），nicotinamide（10），2-hydroxymethyl-5-pyridinol（11），adenosine（12）， and β-daucosterol（13）. Cytotoxicities assay showed that the IC₅₀ value of compound 3 for the hepatic cell line HepG2 was 24.7 μmol·L^-1 （positive control drug cisplatin：4.8 μmol·L^-1），and IC₅₀ value of compound 4 for the hepatic cell line SMMC-7721 was 13.8 μmol·L^-1（positive control drug cisplatin：5.4 μmol·L^-1）. Conclusion:Compound 1 was a new natural compound，compounds 3-8 were obtained from genus Corydalis for the first time，and compounds 2，9-12 were isolated from this plant for the first time. Compound 3 exhibited weak inhibitory effect on hepatic cell line HepG2，and compound 4 exhibited moderate inhibitory effect on hepatic cell line SMMC-7721.The other compounds rest of ones exhibited no obvious inhibitory effect on hepatic cell line HepG2 or SMMC-7721.
