Effect of Erxian Shengbai Decoction Combined with Huangqi Huanagshan Soup on Leukopenia After Chemotherapy and Regulatory Effect on Immunity / 中国实验方剂学杂志

Objective:To observe the clinical efficacy of Erxian Shengbai decoction combined with Huangqi Huang soup for leucopenia (deficiency of spleen and kidney Qi) after chemotherapy, and to investigate the regulatory effect on immune function and cytokines. Method:One hundred and fifty patients were randomly divided into control group（75 cases） and observation group （75 cases）by random number table. Patients in group got batilol tablets by oral administration for 6 weeks, 60 mg/time, 3 times/day. And the patients at stage Ⅲ or Ⅳ additionally received recombinant human granulocyte colony stimulating factor injection (rhG-CSF) for subcutaneous injection,2-5 μg·kg-1·d-1, until the count of neutrophils recovered to 5.0×109个/L (10.0×109个/L for white blood cell). In the control group shengbaikang granules were taken orally,1 bag/time,3 times/day.Patients in observation group additionally received Erxian Shengbai decoction combined with Huangqi Huangshan soup for 6 weeks, 1 doses/day. Number of peripheral blood leukocytes (WBC) and neutrophils (NEUT), time to recovery, number of infections, duration of using antibiotics, dose and duration of rhG-CSF, red blood cell (RBC) count, hemoglobin (Hb), platelets (PLT) and rate of completed chemotherapy were recorded. Scores of traditional Chinese medicine（TCM）syndrome and karnofsky performance scale (KPS) were graded before and after treatment. Levels of T lymphocyte subsets (CD3+, CD4+, CD8+ and CD4+/CD8+) , natural killer cell (NK), interleukin-2 (IL-2), IL-6, and tumor necrosis factor-α (TNF-α) were all detected. Result:In the analysis of rank sum test, to the efficacy for leucopenia in observation group was better than that in control group (Z=2.057, P<0.05). Levels of WBC, NEUT, RBC, Hb and PLT were higher than those in control group (P<0.01). Time to recovery, number of infections and duration of using antibiotics, dose and duration of rhG-CSF were all less than those in control group (P<0.01). After treatment, the recovery rate of WBC and NEUT as well as completed chemotherapy were 76.12% (51/67), 73.13% (49/67) and 92.54% (62/67) in observation group, higher than 57.35% (39/68), 52.94% (36/68) and 79.41% (54/68) in control group (P<0.01). Levels of NK, CD3+, CD4+, CD4+/CD8+ and IL-2 were all higher than those in control group (P<0.01), while levels of CD8+ , IL-6 and TNF-α were lower than those in control group (P<0.05). Conclusion:Erxian Shengbai decoction combined with Huangqi Huangshan soup can promote the recovery of WBC and NEUT, stabilize the immune function, regulate cytokines, improve the microenvironment of bone marrow hematopoiesis, improve the completion rate of chemotherapy, reduce the number of infections and the amount of rhG-CSF, relieve clinical symptoms, and stabilize the quality of life in patients with leukopenia after chemotherapy (deficiency of spleen and kidney Qi).

Prevention of Inonotus obliquus polysaccharides for high power microwave radiation induced testicular injury in rats: an experimental research / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To investigate the effect of Inonotus obliquus polysaccharides on testicular injury induced by exposure to high power microwave (HPM) in rats.</p><p><b>METHODS</b>A total of 30 male Wistar rats were randomly divided into 5 groups, i.e., the normal control group, the microwave radiation model group, the treatment group, the new microwave radiation model group, and the prevention group, 6 in each group. All rats, except those in the normal control group, were exposed to microwave at an average power density of 200 mW/cm2 for 6 min. Rats in the control group and the model group were administered with normal saline by gastrogavage, once a day. Rats in the treatment group and the prevention group were given with Inonotus obliquus polysaccharides by gastrogavage, 2 mL each time (400 mg/kg body weight), once a day. All rats were sacrificed on the 11th day.The sperm density and the rate of sperm deformity were determined. Pathological changes of testis were observed by light microscope and transmission electron microscope.</p><p><b>RESULTS</b>Short-term HPM irradiation could significantly reduce the sperm density and increase the sperm deformity rate (P < 0.05). Meanwhile, obvious pathological changes of testes occurred. Compared with the two model groups, the sperm density increased and the sperm deformity rate decreased in the treatment group and the prevention group (P < 0.05). Under the light microscope, injuries of spermatogenic cells and stromal cells, as well as vascular dilatation and congestion were obviously alleviated in the treatment group and the prevention group. Mitochondrial swelling and endoplasmic reticulum expansion shown by ultrastructural observation were also significantly alleviated. Of them, injuries of spermatogenic cells and inflammation response were milder in the treatment group than in the prevention group.</p><p><b>CONCLUSIONS</b>Inonotus obliquus polysaccharides had significant protective effect on microwave radiation induced testicular injury. Better effect was obtained by therapeutic medication than preventive medication.</p>

Progress of research on Inonotus obliquus / 中国结合医学杂志

Inonotus obliquus has high nutritional and medicinal value, especially in treating malignant tumors, diabetes, cardiovascular disease and AIDS, attracting significant attention from scholars in recent years. In this paper, the biological characteristics, chemical composition and pharmacologic effects of Inonotus obliquus were summarized. And the applications in medicine and food were introduced.
