Chemical synthetic drugs are the main therapeutic drugs for cancer, however, the time-consuming drug development, lengthy treatment, serious side effects and drug resistant of chemical synthetic drugs significantly increase the burden of the patients.In recent years, natural anti tumor substances with good treatment effectiveness and low toxicity, have attracted more and more attentions in studying anti tumor drugs.It is reported that Inonotus obliquus can significantly suppress tumors, while the antitumor components and mechanisms of Inonotus obliquus are rarely reported.In this paper, we will review the antitumor effect, antitumor components and mechanisms of Inonotus obliquus.

Objective To study the clinical features, laboratory index and therapy of hypoplastic myelodysplastic syndrome. Methods 8 patients with hypoplastic MDS by using the method of bone marrow smear and bone marrow biopsy were studied. T lymphocyte subsets were analyzed by flow cytometry. 8 patients were treated with personalized therapy. Results All the patients of this group had hypoplastic bone marrow with more than two parts, bone marrow hypocellularity and characteristics of ineffective hematopoiesis. The analysis of T lymphocyte subsets showed that 5 of 8 patients had abnormal CD+4/CD+8 ratios. After personalized treatment, there were 2 obvious remission cases, 3 partial remission cases, 2 progression cases and 1 inefficacy case. Conclusion Hypoplastic MDS is characterized by bone marrow hypocellularity and ineffective hematopoiesis, which showed immunological abnormalities. Personalized therapeutic strategy may prolong survival in patients with hypoplastic MDS.

Objective To observe the effect of enteral nutritional emulsion on nutritional status and immune function in patients with gastrointestinal cancer. Methods From January 2014 to January 2017,100 patients with gastrointestinal cancer in Yuncheng Central Hospital were selected in the research and randomly divided into two groups according to the digital table, with 50 cases in each group. All the patients underwent chemotherapy, the observation group was given enteral nutritional emulsion during chemotherapy. The indicators of nutritional status, immune function, the effect of chemotherapy, the incidence of adverse reactions were compared between the two groups. Results After treatment,the prealbumin,albumin,transferrin and hemoglobin levels in the observation group were (0. 30 ± 0. 07)g/ L,(32. 93 ± 1. 67)g/ L,(2. 61 ± 0. 15)g/ L,(109. 94 ± 2. 31)g/ L,respectively,which in the control group were (0. 19 ± 0. 09)g/ L,(30. 89 ± 1. 49)g/ L,(2. 49 ± 0. 14)g/ L,(108. 07 ± 2. 04)g/ L,respectively, there were statistically significant differences between the two groups(t = 6. 822,6. 445,4. 135,4. 291,all P < 0. 05).
