ABSTRACT
Malignant tumors are important diseases that threaten human health. Although targeting and immunotherapy have been gradually applied in the treatment of malignant tumors in recent years， which can alleviate the suffering of patients to a certain extent， there are still problems of large adverse reactions and easy drug resistance. At present， chemotherapy is still the main method for the treatment of malignant tumors. While killing tumor cells， chemotherapy also damages normal cells， which often leads to drug toxicity， such as bone marrow suppression， gastrointestinal adverse reactions， liver and kidney function damage， and oral mucosal reactions. Although modern medicines have a certain effect on the toxicity of chemotherapy drugs， there are still limitations. Traditional Chinese medicine（TCM） has a long history of treating malignant tumors， and considers that chemotherapy is a drug with toxin invading the body， exacerbating the "deficiency"， "toxin" and "stasis" of the body， causing damage to Qi， blood and organs， especially in spleen， stomach， liver and kidney， and leading to bone marrow suppression， liver and kidney function injury and other adverse reactions. Studies have confirmed that the use of TCM treatment has a better clinical efficacy. Therefore， new therapies shall be explored based on the basic theory of traditional Chinese medicine. As the core part of the theoretical system of TCM， Viscera-state doctrine is closely related to looking， listening， questioning and feeling the pulse of TCM， and has constantly developed and improved. It has important significance in guiding diagnosis and treatment of diseases. This study is guided by viscera-state doctrine of TCM and based on the etiology and pathogenesis of TCM. It starts with the clinical manifestations of common drug toxicity of chemotherapy drugs， such as bone marrow suppression， gastrointestinal adverse reactions， liver and kidney function damage， oral mucosal reactions， which are external signs of the toxicity of chemotherapeutic drugs， and associates pathological manifestations of viscera to physiological functions. From elephants and Tibetans， it systematically summarizes the viscera characteristics of various common chemotherapeutic drugs and provides new ideas and methods for clinical use of TCM in treating the toxicity of chemotherapeutic drugs， so as to promote the application of viscera-state doctrine in diagnosis and treatment of diseases.
ABSTRACT
Objective To compare the clinical efficacy of acupoint catgut-embedding therapy plus fundamental treatment versus fundamental treatment alone for the prevention and treatment of bone marrow depression in breast cancer patients induced by FEC(fluorouracil, epirubicin and cyclophosphamide) chemotherapy. Methods A total of 46 post-operation breast cancer patients accepting the first cycle of FEC chemotherapy were randomly divided into treatment group and control group, 23 cases in each group. The control group was given fundamental treatment including oral use of Chinese medicine of modified Xiangsha Liujunzi Decoction for regulating stomach and arresting vomiting, modified Guipi Decoction and Gui Lu Erxian Decoction for nourishing blood and generating blood, and western medicine of Batilol Tablets and Vitamin B4 Tablets. The treatment group was given acupoint catgut-embedding therapy on bilateral Zusanli(ST36) and Shenshu(BL23) plus fundamental treatment. The effect on bone marrow depression in the two groups was observed after treatment. Results(1) On post-chemotherapy day 7 and 8, the count of white blood cells (WBC) and neutrophils (NE) in the treatment group was higher than that in the control group, the difference being significant(P < 0.05 or P < 0.01).(2) The utilization of granulocyte colony-stimulating factor(G-CSF) in the treatment group was less than that in the control group, the difference being significant (P < 0.05). (3) On post-chemotherapy day 10, the effect on improving bone marrow depression in the treatment group was superior to that in the control group, the difference being significant (P<0.01) . Conclusion The acupoint catgut-embedding therapy plus fundamental treatment is more effective and safe for the prevention and treatment of bone marrow depression in breast cancer patients induced by FEC chemotherapy than fundamental treatment alone.
ABSTRACT
Objective:To observe the effects of salidroside on the expression of substance P (SP)and neurokinin-1 receptor (NK-1R)of bone marrow cells(BMCs)in bone marrow(BM)depressed anemia mice,and to explore its roles for hematopoietic regulation.Methods:Automatic blood cell analysator was used to detected the changes of peripheral blood cells in each group ,immuno-histochemistry and reverse transcription-polymerase chain reaction ( RT-PCR) were used to analyze the expressions of SP and its receptor NK-1R of BMCs in each group respectively.Results: Peripheral blood testing results showed that the number of white blood cells (WBC),red blood cells(RBC)and hemoglobin(HB)of model group were significantly decreased when compared with control group.Compared with model group ,low-dose,middle-dose and high-dose salidroside obviously elevated the number of white blood cells ,and middle-dose salidroside obviously elevated the number of platelets.Immunohistochemistry studies showed that the expression of SP and its receptor NK-1R of BMCs was found in each group.Compared with control group , the expression of SP of BMCs was decreased obviously in model group(P0.05),and the expression of SP and its receptor NK-1R of BMCs was increased significantly in low-dose,middle-dose and high-dose salidroside groups (P<0.05).RT-PCR data showed that the expression of SP mRNA of BMCs was increased obviously in model group ,low-dose,middle-dose and high-dose salidroside groups when compared with control group (P<0.05).The expression of NK-1R mRNA of BMCs was un-detected in control group and model group.The expression level of NK-1R mRNA of BMCs was elevated gradually with the increase of salidroside dosage in low-dose,middle-dose and high-dose salidroside groups.Conclusion: The mRNA and protein expressions of SP and its receptor NK-1R of BMCs were up-regulated significantly by salidroside in dose-dependent manner.These data suggest that salidroside could participate in the recovery of hematopoietic function of BM depressed anemia mice by increasing the expression of SP and its receptor NK-1R of BMCs.
