Shuanghuang Shengbai Oral Liquid

To study the efficacy and safety of Shuanghuang Shengbai Granule (, SSG), a traditional Chinese herbal medicine, on myelosuppression of cancer patients caused by chemotherapy.

A total of 330 patients were randomly assigned to the treatment group (220 cases, analysed 209 cases) and the control group (110 cases, analysed 102 cases) with a 2:1 ratio by envelope method. The patients in the treatment group at the first day of chemotherapy started to take SSG for 14 days, while the patients in the control group took Leucogon Tablets. The changes of the blood routine, clinical symptoms and immune function in both groups were observed for safety and efficacy evaluation.

At the 7th day of chemotherapy, the white blood cells (WBCs) level in the treatment group was significantly higher than that in the control group (P<0.05). After treatment, the WBCs rate in the normal range accounted for 50.2% in the treatment group, the myelosuppression of WBCs and neutrophil were mainly grade I, while 8.1% and 5.7% of patients emerged grade III and grade IV myelosuppression, respectively. The incidence of myelosuppression of the treatment group was significantly lower than that of the control group (P<0.05). The total effective rate of Chinese medicine syndrome in the treatment group was significantly higher than that in the control group (84.2% vs. 72.5%, P<0.05). The immune cell levels in both groups were maintained in the normal range. Compared with that before treatment, the levels of CD3⁺ and CD4⁺ cells were significantly increased in the treatment group after treatment (P<0.05). The discrepancy of CD3⁺ and CD4⁺ cell activity before and after treatment in both groups were significantly different (P<0.05). No obvious adverse event occurred in both groups.

SSG had a protection effect on bone marrow suppression, and alleviated the clinical symptoms together with clinical safety.

Objective To observe the regulation of Shuanghuang Shengbai Granule (SHSBG) on regulating Wnt signaling pathway in tumor-bearing mice with chemotherapy induced myelosuppression. Methods Chemotherapy induced myelosuppression model was established in Lewis lung tumor bearing mice by intraperitoneal injection of cyclophosphamide (CTX). And then they were intervened by SHSBG. Routine white blood cell (WBC) count, red blood cell (RBC) count, platelet count, and tumor mass were calculated. Ratios of bone marrow hematopoietic stem cell (Sca, CD34 double positive cells) were detec- ted by flow cytometry. mRNA expression of main genes in Wnt signaling pathway (Wnt, β-catenin, Frizzted, DSH, GSK3) were detected using real time fluorescent quantitative PCR. Results The number of WBC and ratio of hematopoietic stem cells in the treatment group were higher than those in the model group (P<0. 05). Expressions of Wnt, β-catenin, Frizzted, DSH, and GSK3 mRNA in the bone marrow were higher in the treatment group than in the model group (P <0. 05). Expressions of Wnt, β-catenin, Frizzted, and DSH mRNA expression in tumors were lower in the treatment group than in the model group (P <0. 05). There was no statistical difference in counts of RBC and platelet, tumor mass, or GSK3 mR- NA expression among all groups (P >0. 05). Conclusions The mechanism for SHSBG treating myelo-suppression was related to regulating Wnt signaling pathway. Besides, it had dual regulation effect on Wnt signaling pathway, up-regulating expressions of main genes in Wnt signaling pathway while inhibiting ex- pressions of partial genes in tumors.
