Methods: Sixty three patients with malignant tumor were divided into three groups: prevention treatment (PT) group (n=23 cases),post chemotherapy treatment (PCT) group( n=22 cases), Western medicine (WM) group ( n=18 cases). The patients in PT, PCT and WM groups were treated respectively from the fifth day on before chemotherapy and from the first day on after chemotherapy, 18 days in all. The patients in WM group were administered Batilol and Leucogen from the first day on after chemotherapy. Changes of leukocytes and immunoglobulin before and after treatment were observed. Results: 1) Acupoint injection of Astragalus Root injectio could increase the number of leukocytes and immunoglobulin content and its effect was better than that of Western medicine (P<0.05); 2) The effect of PT group was better than that of PCT group in preventing and treating virulent and side effects of chemotherapy (P<0.05). Conclusion: It should be stressed on prevention of malignant tumor by using acupoint injection of Astragalus Root for relieving virulent and side effects of chemotherapy.展开更多

Methods: Sixty NSCLC patients were randomly divided into the treated group (n=30,treated with AI combined with chemotherapy) and the control group (n=30, treated with chemotherapy alone). Chemotherapy of MVP protocol was applied to both groups. AI was supplemented to the treated group by intravenous dripping 60 ml per day. Treatment of 21-28 days consisted one treatment cycle, and 2-3 cycles were applied. WResults: The effective rate in the treated group was 40.0% and in the control group was 36.7%, the mean remission rate in them being 5.4 month s and 3.3 months, the median survival period 11 month and 7 month and the 1-year survival rate 46.75% and 30.0%, respectively, the difference of these indexes between the two groups were all significant (P<0 05). Moreover, the clinical improving rate and QOF elevation rate in the treated group was 80.4% and 43.3%, as compared with those in the control group (50.0% and 23.3% respectively), the different was also significant (P<0 01). Conclusion: AI combined with chemotherapy can significantly improve the QOF in NSCLC patients of advanced stage.展开更多

Study selection: Only randomized controlled trials(RCTs) for the prevention or treatment of any one of gastrointestinal side effects, namely nausea, vomiting, oral ulceration, diarrhea and constipation, of CHM with or without western medicine(WM) vs WM, placebo or no treatment were included. Data Extraction: Independent extraction of articles was first performed by four medical students using predefined data fields. Then, all data, including study quality indicators, was checked by two authors.Results: Eighty-six RCTs involving 7076 cancer patients were found and analyzed in this review. Because of the heterogeneity of study design and low overall methodological quality, only descriptive summaries were performed. Beneficial effects were found in some CHM interventions,regardless of being taken alone or taken with WM. Moreover, none of serious adverse effect was reported. However, same intervention had not been repeatedly investigated by different research teams.Conclusions: Implications of the analysis support the efficacy and safety of CHM for the management of gastrointestinal side effects.However, definite clinical recommendation for particular CHM intervention still cannot be made due to low methodological quality of included studies and lack of duplicated verification. Further large scale and high quality RCTs on the same CHM interventions are suggested.展开更多

The application of 808 nm laser as the excitation source could achieve better penetration depth and avoid overheating problem. The combination of UCNPs and RBS could realize the on-demand release of NO at desired time and location by simply controlling the output of NIR laser.Cellular uptake results showed that more nanoparticles were internalized in cancer stem-like cells(CSCs)rather than non-CSCs. Therefore, a synergistic cancer therapy strategy to eradicate both CSCs and nonCSCs simultaneously was developed. Traditional chemo-drug could inhibit non-CSCs but has low killing efficiency in CSCs. However, we found that the combination of NO and chemotherapy could efficiently inhibit CSCs in bulk cells, including inhibiting mammosphere formation ability, decreasing CD44^+/CD24^- subpopulation and reducing tumorigenic ability. The mechanism studies confirmed that NO could not only induce apoptosis but also increase drug sensitivity by declining drug efflux in CSCs. This UCNPsbased platform may provide a new combinatorial strategy of NO and chemotherapy to improve cancer treatment.展开更多
