[Clinical application evaluation of Guidelines for Diagnosis and Treatment of Cancer in Traditional Chinese Medicine].

This study aims to evaluate the adaptability and applicability of Guidelines for the Diagnosis and Treatment of Cancer in Traditional Chinese Medicine. The assessment methods included adaptability assessment and applicability assessment. The adaptability assessment was based on the questionnaire survey to evaluate the familiarity, utilization, quality, and clinical application of the Guidelines; applicability assessment was based on the prospective observation of 853 clinical cases to investigate the applicability and effect of the Guidelines, including effectiveness, economy and safety. Statistical analysis for basic description, construction of different comparison groups for cross or hierarchical statistical test, multi-factor analysis, and confounding factors were used in the study. Adaptability assessment results showed that 63.03% of TCM doctors considered guidelines as good or very good applicability and 4.24% of TCM doctors considered guidelines with very poor applicability in clinical practice. For the applicability evaluation, TCM doctors considered that the "overall efficacy and technology level", "satisfactory degree" and "adaptability in clinical practice" of the guideline were 85.46%, 80.43% and 69.40% respectively. The results showed that guideline was well known among TCM doctors, especially junior TCM doctors. Adaptability and applicability of Guidelines were totally good but the quality and adaptability of the intervention schemes were still week, so the quality of Guidelines should be improved by revision.

[Comparative study of Radix Hedyseri as sulstitute for Radix Astragali of yupingfeng oral liquid on cellular immunity in immunosuppressed mice].

OBJECTIVE: To study on Radix Hedyseri as substitute for Radix Astragali of Yupingfeng oral liquid on cellular immunity in immunosuppressed mice. METHODS: The model of immunosuppression mice were induced by Cyclophosphamide. And the same dose of Radix Hedyseri and Radix Astragali alternative Yupingfeng oral liquid was intragastric administrated into mice; Antagonistic experiments were observed in vivo. Determined the thymus gland index, spleen index, phagocytosis of the macrophage, proliferation index of T lymphocyte, kill and wound activity, T lymphocyte subgroup, and content of IL-13 of serum. RESULTS: Yupingfeng oral liquid and Yuping-feng aqueous extract of Radix Hedyseri substitute Radix Astragali both could significant raise thymus gland index and spleen index, and clearly increase the phagocytosis of the macrophage. They both could antagonize immunosuppressive action caused by Cyclophosphamide, which could promote T lymphocyte proliferation, kill and wound activity, quantity of T lymphocyte subgroup, and production of IL-1beta with different degree. And Yupingfeng aqueous extract of Radix Hedyseri substitute Radix Astragali increased spleen index and T lymphocyte proliferation was better than those of Yupingfeng oral liquid. CONCLUSION: Radix Hedyseri and Radix Saposhnikoviae, compatible with Rhizoma Atractylodis Macrocephalae compared with Yupingfeng oral liquid in cell immunity regulation has a similar role, and better in the recovery of spleen weight and T cell proliferation.

[Comparative study of Hedysari Radix and Astragali Radix alternative classic tonification prescriptions on humoral immunity in immunosuppressed mice].

OBJECTIVE: To compare the regulating effects of Hedysari Radix and Astragali Radix alternative classic tonification prescriptions on humoral immunity in immunosuppressed mice. METHODS: The immunosuppressed mouse model was induced by cyclophosphamide. The mice were administered intragastically with same dose of Hedysari Radix and Astragali Radix alternative Buzhong Yiqi Yiqi Yangxue,Yupingfeng oral liquid and Fuqi Zhihan granules for antagonistic experiments in vivo. And spleen index, HC50, CD19+B lymphocyte subgroup and content of serum IL-4 were determined after treatment. RESULTS: Both groups of Hedyseri Radix and Astragali Radix could antagonize immunosuppressive action caused by cyclophosphamide. They both could significantly raise spleen index, HC50, CD19+ B lymphocyte subgroup and content of serum IL4 in different degree. And Yupingfeng aqueous extract of Hedysari Radix substitute Astragali Radix was better than Yupingfeng oral liquid in raising spleen index. There were no significant differences among the rest Hedysari Radix and Astragali Radix alternative groups. CONCLUSION: Hedysari Radix compatibility with other drugs compared with original prescription has similar role in humoral immunity regulation.

[Proteomics analysis of the synergy effect of Radix Hedysari polysaccharides combined with chemotherapy on S180 tumor cells].

OBJECTIVE: To analyze the differentially expressed proteins of the synergy effect of Radix Hedysari polysaccharides (HPS)combined with chemotherapy (Cy) on S180 tumor cells. METHODS: The total proteins extracted from the HPS combined with Cy treated S180 cells in tumor-bearing mice were separated by two dimentional gel electrophoresis (2-DE)and compared with those from Cy treated S180 cells using PDQuest 8.0 software. Mass spectrometry was applied to identify the differentially expressed proteins. Western blot was used to determine the differential expression of one protein. RESULTS: Twenty-four differentially-expressed proteins in HPS group were discovered. The five differential expressed proteins among twenty-four proteins were later identified by mass spectrometry and Mascot software as heat-shock protein hsp84 (HSP90beta), apolipoprotein A, albumin, heat shock protein beta-1 (HSP27)and unnamed protein product, including one up regulated and four down regulated expressed proteins respectively. Results from Western blot manifested the same trend as from proteomics analysis. CONCLUSION: Proteomics technique can be used to discover target proteins associated with the synergy effect of HPS combined with Cy on S180 tumor cells, involving some important proteins related to energy metabolism, oxidative stress and apoptosis induction signal transduction.

Proteomic analysis of the effect of triterpenes from Patrinia heterophylla on leukemia K562 cells.

For centuries, Patrinia heterophylla had been used in China to treat many diseases including tumor. Triterpenes has been identified as the major active constituents in Patrinia heterophylla. To elucidate the antitumor mechanism of triterpenes from Patrinia heterophylla1 (TPH), a proteomic analysis is carried out with TPH treatment in K562 cells. The total proteins extracted from TPH treated K562 cells are analyzed by two dimensional gel electrophoresis (2-DE) and compared with those untreated K562 cells. Mass spectrometry is applied to identify the differentially expressed proteins. Twenty-three differentially expressed significant proteins are discovered. Eight proteins are later identified by mass spectrometry (MALDI-TOF-MS) and Mascot software. Among them, four proteins are up-regulated (Aldolase A, Glyceraldehyde-3-phosphate dehydrogenase, Flavin reductase and Hemoglobin subunit) and four proteins were down-regulated (Heat-shock protein 90 〈Alpha〉 (HSP90-〈Alpha〉), Eukaryotic translation initiation factor 5A, Moesin, tublin) by TPH treatment in K562 cells. The identified proteins are associated with energy metabolism, oxidative stress, apoptosis, signal transduction, differential induction, and protein biosynthesis. These findings might provide valuable insights into the antitumor mechanism of TPH in K562 cells.
