Abstract
Cisplatin (CP) is one of the most effective and widely used compounds in the treatment of disease, including cancer, but is known to induce toxicity in patients. Rutin (RUT) is a flavonoid glycoside from Sophora japonica L. that has been shown to possess antioxidative, anti-inflammatory, and antiviral properties. RUT is also known to attenuate cardiotoxicity, isoproterenol-induced cardiac fibrosis, and ischemia/reperfusion-associated hemodynamic alteration, and prevents high glucose-induced renal glomerular endothelial hyperpermeability. In this study, we investigated the effect of RUT on CP-induced nephrotoxicity. CP was used to induce toxicity in human mesangial cells (HMCs), HMCs were pretreated with different concentrations of RUT before being exposed to 10 μg/mL of CP. A positive group was pretreated with antioxidant agent N-acetylcysteine prior to CP administration. At doses between 12.5 and 25 μM, RUT prevented CP-induced reduction in cell viability. Treatment with RUT suppressed intracellular reactive oxygen species and malonic dialdehyde levels and inhibited cell apoptosis. RUT reversed the CP-induced upregulation of p53, cleaved-caspase-3, and increased pro-caspase-3 and pro-caspase-9 levels. In conclusion, the RUT can relieve CP-induced nephrotoxicity by inhibiting the p53/caspase signaling pathway.

Cancer nursing. 2019;(6):E24-E31
Abstract
BACKGROUND Patients with gastrointestinal tract (GIT) cancer undergoing chemotherapy often experience several symptoms that constitute symptom clusters and can cause patients to suffer. Effective interventions are lacking for this kind of patients. OBJECTIVE The aims of this study were to test the feasibility and acceptability of a cognitive-behavioral (CB) intervention developed for Chinese patients with GIT cancer undergoing chemotherapy and to estimate the efficacy of the intervention for symptom clusters. METHODS In this pilot, quasi-randomized controlled trial, 40 patients were assigned to the CB intervention or control group. The CB intervention, considering characteristics of patients and Chinese culture, contained 4 sections including cognitive reframing, cancer-diet education, relaxation, and exercise techniques. Symptom clusters, illness perception, anxiety, and depression were measured. RESULTS Thirty-nine patients (97.5%) completed the study program and expressed willingness to follow the intervention. Compared with the control group, all outcomes were improved (all P < .05) in the CB group after the intervention, except for the gastrointestinal symptom cluster (t = 0.25, P = .802). In the CB group, the scores of all outcomes (all P < .05) decreased except for depression (t = 1.76, P = .095). CONCLUSION The CB intervention is partially feasible and acceptable. It may also help to improve part of the symptom clusters of Chinese patients with GIT cancer undergoing chemotherapy. However, some modifications are needed in future studies to better test effectiveness. IMPLICATIONS FOR PRACTICE Symptom management remains a major problem in clinical nursing. Such a CB intervention can be beneficial to the clinical management of symptom clusters.

Abstract
BACKGROUND Platinum-based chemotherapy is one of the standard treatments for advanced nonsmall cell lung cancer (NSCLC). Despite on an effective treatment for advanced NSCLC patients, its high toxicity and limited clinical effects have raised big concerns. Astragalus injection (AGI) has been commonly employed as an adjutant chemotherapy drug for NSCLC in China. This review was conducted to evaluate the beneficial of AGI in combination with platinum-based chemotherapy in advanced NSCLC. METHODS We collected all studies about AGI plus platinum-based chemotherapy for advanced NSCLC in the PubMed, EMBASE, China National Knowledge Infrastructure Database, the Cochrane Library, Wanfang Database, China Biological Medicine Database, and Chinese Scientific Journal Database established on July 2018 without language restriction. Cochrane handbook was applied to assess the quality of included trials. Stata (version 12.0) and RevMan (version 5.3) were employed for data analysis. The quality of the evidence was assessed with the GRADE approach. RESULTS Nineteen randomized controlled trials (RCTs) including 1635 patients were included to determine the effectiveness and safety of AGI combined with platinum-based chemotherapy in the treatment of NSCLC. The result of meta-analysis indicated that comparing with chemotherapy alone, AGI combined chemotherapy could significantly improve the objective response rate (relative risk [RR] = 1.19, 95% confidence interval [CI] [1.06, 1.33], P = .002), the Karnofsky performance status (RR = 2.28, 95% CI [1.63, 3.18], P < .00001), and 1-year survival rate (RR = 1.40, 95% CI [1.16, 1.70], P = .0005), meanwhile increase the percentages of CD3 (weighted mean differences [WMD] = 11.98, 95% CI [8.0, 15.96], P < .00001), CD4 (WMD = 2.98, 95% CI [0.45, 5.52], P = .02), CD4/CD8 (WMD = 0.33, 95% CI [0.20, 0.46], P < .00001), and NK cells (WMD = 9.5, 95% CI [7.25, 11.76], P < .00001), decrease the incidence of leukopenia (RR = 0.52, 95% CI [0.44, 0.61], P < .00001), platelet toxicity (RR = 0.62, 95% CI [0.50, 0.76], P < .00001), and vomiting (RR = 0.72, 95% CI [0.60, 0.87], P = .0006). Based on the system evaluation results, the GRADE system recommendation grading method was adopted to evaluate the evidence quality. The results showed that the level of evidence was low. CONCLUSIONS The AGI apparently has attenuation and synergistic efficacy to platinum-based chemotherapy patients. However, considering the limits of articles included in the present researches, the recommendation is likely to be weak. High-quality RCTs are urgently used to generate conclusive results.

Calumenin and fibulin-1 on tumor metastasis: Implications for pharmacology.
Zheng, P, Wang, Q, Teng, J, Chen, J
Pharmacological research. 2015;:11-5
Abstract
Tumor metastasis is a key cause of cancer mortality, and inhibiting migration of cancer cells is one of the major directions of anti-metastatic drug development. Calumenin and fibulin-1 are two extracellular proteins that synergistically inhibit cell migration and tumor metastasis, and could potentially be served as targets for pharmacological research of anti-metastatic drugs. This review briefly introduces the multi-function of these two proteins, and discusses the mechanism of how they regulate cell migration and tumor metastasis.

Abstract
OBJECTIVE Sorafenib, an oral multikinase inhibitor, is the proved therapy method for patients with advanced hepatocellular carcinoma (HCC). Based on heat delivery, Radiofrequency ablation (RFA) has been found to achieve complete neoplasm necrosis. It is the most widely performed percutaneous therapy for HCC. However, Study associated combined Sorafenib with RFA therapy for patients with advanced HCC has never been reported. The aim of present study is to explore the efficacy and safety of sorafenib combined with RFA therapy for the patients with medium-sized HCC. PATIENTS AND METHODS A total of 62 patients diagnosed as HCC were involved in this study. All patients were randomly assigned to sorafenib and RFA (n=30) or RFA-alone (n=32) treatment groups. Treatment outcomes, including recurrence rates, time to progression (TTP) and adverse reactions induced by sorafenib were observed and recorded to assess the efficacy and safety of the combination method. RESULTS During the overall follow-up period, the recurrence rate of the combination subgroup was 56.7% (17/30), and that of the RFA-alone subgroup was 87.5% (28/32) (p < 0.01). The median TTP was 17.0 months in the combination therapy vs. 6.1 months in the RFA-alone (p < 0.05). Hand-foot skin reactions were reported by 83.3% (25/30) of patients and 46.7% (14/30) reported diarrhea while the most adverse events (AEs) were mild to moderate in the combination subgroup. CONCLUSIONS Sorafenib combined with RFA significantly decreased recurrence rates and prolonged the survival time of medium-sized HCC patients. The combination therapy is safer and more effective than the control without unexpected side effects. Furthermore, the earlier application, the better results were.

Abstract
The green tea constituent, (-)-epigallocatechin-3-gallate (EGCG), has chemopreventive and anticancer effects. This is partially because of the selective ability of EGCG to induce apoptosis and death in cancer cells without affecting normal cells. In the present study, the activity of EGCG against the myeloma cell line, KM3, was examined. Our results demonstrated, for the first time, that the treatment of the KM3 cell line with EGCG inhibits cell proliferation and induces apoptosis, and there is a synergistic effect when EGCG and bortezomib are combined. Further experiments showed that this effect involves the NF-kappaB pathway. EGCG inhibits the expression of the P65 mRNA and P65/pP65 protein, meanwhile it downregulates pIkappaBalpha expression and upregulates IkappaBalpha expression. EGCG also activates caspase-3, -8, cleaved caspase-9, and poly-ADP-ribose polymerase (PARP) and subsequent apoptosis. These findings provided experimental evidence for efficacy of EGCG alone or in combination with bortezomib in multiple myeloma therapy.
