Objective: To probe into the mechanism and interventional effects of silybin-phospholipid complex on amiodarone-induced steatosis in mice. Methods: Eight-week-old male C57BL/6 mice were divided into three groups (5 mice in each group): a control group (WT) with normal diet, a model group with amiodarone 150mg/kg/d by oral gavage (AM), and an intervention group on amiodarone 150mg/kg/d combined with silybin-phospholipid complex(AM+SILIPHOS. All mice were fed their assigned diet for one week. Then, one week later, serum alanine aminotransferase, aspartate aminotransferase, triglyceride, total cholesterol and high-density lipoprotein were detected of each group. A liver pathological change was observed by oil red O and H&E staining. Ultrastructural pathological changes of hepatocytes were observed to evaluate the intervention effect by transmission electron microscopy. RT-q PCR was used to detect the expression of peroxisome proliferator-activated receptor alpha and its regulated lipid metabolism genes CPTI, CPTII, Acot1, Acot2, ACOX, Cyp4a10 and Cyp4a14 in liver tissues. Intra-group comparison was done by paired t-test. One-way ANOVA was used for comparison between groups and semi-quantitative data were tested using Mann-Whitney U test. Results: Oil Red O and H&E staining results of liver tissue in the intervention group showed that intrahepatic steatosis was significantly reduced when compared to model group. Transmission electron microscopy showed that the model group had pyknotic nuclei, mitochondrial swelling, structural damage, and lysosomal degradation whereas the intervention group had hepatic nucleus without pyknosis, reduced mitochondrial swelling and slight structural damage than that of model group. RT-q PCR results showed that the expression of peroxisome proliferator-activated receptor alpha, CPTI, CPTII, Acot1, Acot2, ACOX, Cyp4a10 and Cyp4a14 were increased in the model group but the expression of CPTI, Cyp4a14, Acot1 and peroxisome proliferator-activated receptor alpha were decreased in the intervention group (P < 0.05). Conclusion: Silybin-phospholipid complex can alleviate amiodarone-induced steatosis, and its mechanism may play a role in protecting mitochondrial function and regulating fatty acid metabolism. Thus, silybin-phospholipid complex has potential intervention effect on amiodarone-induced fatty liver.

Objective: To investigate the inhibitory effect of AKR1B10 inhibitor combined with sorafenib on hepatocellular carcinoma (HCC) xenograft growth. Methods: HepG2 xenograft model was established in nude mice. The mice were then randomly divided into four groups: control group, epalrestat monotherapy group, sorafenib monotherapy group and combination treatment group. Tumor volume, tumor weight, T/C ratio and the change in body weight of nude mice in each group were compared to evaluate the curative effect. Immunohistochemistry staining was used to detect the expression of Ki-67 in tumor tissues to evaluate the proliferation status of tumor cells. One-way analysis of variance was used to compare the differences between the groups. Student's t-test was used to test means of two groups and chi-square test was used for multiple samples. Results: The differences of the grafted tumor volume before and after treatment between the control group, epalrestat group, sorafenib group and combined therapy group was 238.940 ± 39.813, 124.991 ± 84.670, -26.111 ± 11.518, and -54.072 ± 17.673(mm(3)), respectively, (F = 37.048, P < 0.001). The tumor mass were 0.273 ± 0.140, 0.158 ± 0.078, 0.079 ± 0.054, 0.045 ± 0.024 (g), (F = 16.594, P < 0.001); T/C ratio were 100%, 57.9%, 28.9%, 16.5%, and Ki-67 positive rate were 23.295 ± 6.218, 13.503 ± 3.392, 7.325 ± 2.257, 4.664 ± 1.189 (%), (χ(2) = 822.203, P < 0.001) . The tumor volume (t = -3.579, P = 0.002) and Ki-67 positive rate (t = -10.003, P < 0.001) in epalrestat monotherapy group were significantly lower than control group. The tumor volume (t = 2.056, P = 0.025), tumor mass (t = 2.101, P = 0.043), and Ki-67 positive rate (t = -2.850, P = 0.005) in combination treatment group were significantly lower than sorafenib monotherapy group. Compared with the control group, the body weight of nude mice in the treatment group decreased to a certain extent, but there was no statistically significant difference between epalrestat monotherapy group and control group (t = -1.599, P = 0.262), and combined therapy and sorafenib monotherapy group (t = -0.051, P = 0.96). Conclusion: AKR1B10 inhibitor enhanced the inhibitory effect of sorafenib on hepatocellular carcinoma xenograft.

Bladder cancer is one of the common malignant tumors in China. Three-quarter bladder cancer is non-muscle invasive bladder cancer with a high recurrence rate. Intravesical therapy can reduce the risk of recurrence and progression in bladder cancer. According to the recent updates of evidence-based medical evidence at home and abroad, as well as the deepening of domestic experts' research on the diagnosis and treatment of bladder cancer, the consensus has summarized the current intravesical therapy for non-muscle invasive bladder cancer in China, including the indications, contraindications and methods for intravesical therapy, as well as commonly used drugs in bladder cancer.

To explore the effect of down-regulation of growth arrest and DNA damage inducible protein 45β (GADD45β) on the PC9 lung adenocarcinoma cells.
 Methods: GADD45β gene siRNA sequence was designed and synthesized, which was transfected into PC9 lung adenocarcinoma cells through lentivirus transfection. Quantitative real-time PCR (qRT-PCR) and Western blot are used to examine the mRNA and protein levels of GADD45β in PC9 cells before and after the transfection. Annexin V-allophycocyanin (APC) double-staining flow cytometry was used to detect the apoptosis level after the transfection. The intracellular DNA content after transfection was detected by flow cytometry. The percentage of the cells at each period of cell cycle was calculated, and the effect of RNA interference on the cell growth were analyzed. The effects of RNA interference on the tumor-formation ability of cells were tested by counting the number of clones. MTT assay was used to test the half maximal inhibitory concentration (IC50) of PC9 cells for gefitinib. 
 Results: The 5'-AAATCCACTTCACGCTCAT-3' sequence was identified as the effective sequence for GADD45β gene RNA interference. The mRNA and protein expression levels of GADD45β were markedly decreased (both P<0.05) at 48 h after transfection of GADD45β-siRNA, which resulted in the increased apoptosis rate (P<0.05), decreased tumor clone number (P<0.05) and increased percentage of PC9 cell at the S stage and G2/M stage (P<0.05). The IC50 for gefitinib was decreased obviously (P<0.05).
 Conclusion: Down-regulation of GADD45β can reduce the colony-forming ability of PC9 cells, promote the cell apoptosis, and enhance the sensitivity of PC9 cells to gefitinib.

To explore the differential expression of serum miRNAs in patients of advanced non- small cell lung cancer (NSCLC) treated by gifitinib before and after acquiring drug resistance.
 Methods: A total of 4 patients with advanced NSCLC from Affiliated Hospital of Yueyang Vocational Technical College, who acquired drug resistance during gefitinib therapy from June 2013 to June 2015, were enrolled. Serum samples were collected before treatment and after acquiring drug resistance. MicroRNA (miRNA) microarray was used to assess the levels and compositions of miRNAs in serum. Real-time RT-PCR was used to validate the results of miRNAs with significant differences in expression. The candidate miRNAs inhibitors and mimics were transfected into lung cancer cells by liposome, and the sensitivity of lung cancer cells to gifitinib was detected.
 Results: The miRNA microarray showed that there were significantly differential expression of miRNAs in serum of NSCLC patients after acquiring drug resistance, and 24 miRNAs were changed in more than 2-fold. Among them, 19 miRNAs were up-regulated and 5 miRNAs were down- regulated (both P<0.05). Especially, the expression of miR-21 in serum of NSCLC patients after obtaining resistance was up-regulated more than 10-fold compared with that before treatment. The results of RT-PCR was consistent with the results of miRNA microarray. The up-regulation of miR-21 in lung cancer cells could elevate the half maximal inhibition concentration (IC50) of gefitinib, and the down-regulation of miR-21 in lung cancer cells could reduce the IC50 of gefitinib (both P<0.05).
 Conclusion: There is differential expression of miRNAs in serum of NSCLC patients before treatment and after acquiring drug resistance during gefitinib therapy. The up-regulation of miR-21 may be involved in regulating the acquiring drug resistance of gefitinib.

Pterostilbene (3,5-dimethoxy-4'-hydroxystilbene) is a polyphenolic compound primarily found in blueberries, grapes, and a tree wood, pterocarpus marsupium. Studies demonstrate that pterostilbene inhibits a variety of cancers, such as lung, breast, stomach, colon, etc. The anti-cancer activities are related to the regulation of several hallmarks of cancer. Moreover, pterostilbene exhibits much greater bioavailability and bioactivity than resveratrol which warrants further investigation in the anti-cancer functions and mechanisms.

Over the past decade, the management model of cancer patients has gradually shifted to individual mode based on molecular mutation detection. Epidermal growth factor receptor (EGFR) gene mutation is an important driving factor in non-small cell lung cancer (NSCLC). Compared with traditional chemotherapy, EGFR-targeted therapy shows significant safety and efficacy. However, not all patients with EGFR mutations are eligible for EGFR-targeted therapy, and different types of mutations often indicate different clinical outcomes, such as the sensitive mutations EGFR 19-Del, L858R, and the resistance mutation. In addition, the third-generation TKI drugs Osimertinib (AZD9291) and Rociletinib (CO-1686) have been developed to further benefit patients with primary TKI resistance caused by T790M mutation of EGFR. Therefore, detection of the EGFR mutation status of patients before treatment, and continuously monitoring the mutation of drug resistance genes during the treatment process is useful for the management of targeted drugs in NSCLC patients. In recent years, the rapid development of "liquid biopsy" technology has made it possible to use non-invasive methods to monitor drug resistance mutations in real time. In this paper, we reviewed the clinical application of various non-invasive detection techniques for EGFR mutations in NSCLC in different liquid samples.

Lung cancer is the one of the malignant tumor of the highest morbidity and mortality over the world, and non-small cell lung cancer (NSCLC) makes up about 80%. Nowadays, molecular targeted therapy has been the first-line treatment for NSCLC. Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are increasingly used in the clinical treatment, but the EGFR-TKIs acquired resistance becomes the bottleneck of continuation of EGFR-TKIs therapy. Epithelial-mesenchymal transition (EMT) is a biological phenomenon in which epithelial cells are transformed into mesenchymal cells. EMT promoted metastasis, invasion of lung cancer and conferred characteristic of stem cell on cancer cells. Meanwhile, EMT is one of an important cause of EGFR-TKIs resistance in NSCLC. The recent studies have found that resistant cells restored the sensitivity to EGFR-TKIs by reversing EMT which suggested that the target of EMT may contribute to inhibit or even reverse the resistance of EGFR-TKIs. Here we make a review about research progress of EMT in EGFR-TKIs resistance in NSCLC.

Objective: To evaluate the anthracyclines-induced cardiotoxicity in patients with early-stage breast cancer. Methods: This retrospective study analyzed data of 64 patients (aged from 36 to 59 years old) with early-stage breast cancer after surgery. Patients were divided into ACT group (n=21), FAC group (n=19) and EC group (n=24). The NCI CTC 4.0 scores was used to evaluate the side effects at the time of 2 weeks, 4 weeks and 6 weeks after chemotherapy. Meanwhile, the level of cTnT, the incidence of abnormal electrocardiogram (ECG) and left ventricular ejection fraction (LVEF) were used to evaluate the anthracyclines-induced cardiotoxicity, the follow-up observation points were as follows: at the acute cardiotoxicity (time A), subacute cardiotoxicity (time B), 24 months after chemotherapy (time C), 36 months after chemotherapy (time D), 48 months after chemotherapy (time E), 60 months after chemotherapy (time F). The 3-years and 5-years overall survival and progress free disease survival among three groups were compared. Results: The ages, clinical stage, the size of tumor, axillary lymph node positivity and Eastern Cooperative Oncology Group Scores were similar among three groups (P>0.05); the incidence of side effects level 4 was 0. The levels of cTnT in the three groups were significantly lower than those at the baseline and time points C, D, E and F (all P<0.05), and the levels of cTnT were significantly higher in EC group than in FAC and ACT group at the time points B, C, D, E and F (P<0.05); however, the incidence of abnormal ECG and LVEF was similar among the 3 groups (P>0.05). The 5-year overall survival was 95.2% (20/21) ,100% (19/19) and 95.8% (23/24) in ACT group, FAC group and EC group, respectively; 5-year progress free disease survival was 95.2% (20/21) ,94.7% (18/19) and 91.7% (22/24) in ACT group, FAC group and EC group, respectively (P>0.05) . Conclusions: Patients with early-stage breast cancer after surgery could tolerate the anthracyclines-induced cardiotoxicity. Three chemotherapy schemes of ACT, FAC and EC, especially the EC protocol, could affect the myocardial damage. However, outcome is comparable among patients treated with above chemotherapy schemes in this patient cohort.

To explore the association between expression of ADAM17 and cetuximad resistance in human colorectal cancer SW480 cells.

The response to anti-vascular endothelial growth factor (VEGF) treatment is variable. It is generally measured in terms of changes in correlated functional and/or anatomical outcomes, and patients are then classified as optimal response, poor response and non-response. The precise cause of non-response remains undetermined. A variety of factors could account for poor or non-response to anti-VEGF therapy, such as age, baseline vision, disease course, lesion characteristics and genomic polymorphism. At the present time, many studies on the genetic factors of non-response or poor response to anti-VEGF treatment mainly focus on VEGF genes (VEGF-A, VEGFR-2), complement factor H (CFH), age-related maculopathy susceptibility 2 (LOC387715/ARMS2), high temperature factor A-1 (HTRA1), interleukin-related gene (IL-8 rs4073) and so forth. It is still worthy of further investigations that how to assess genetic reasons for non-response or poor response, so that we can provide individualized treatment sequences and predict the response to anti-VEGF therapy.

Objective: To investigate the effect of tumor-associated macrophages on the stemness of esophageal cancer cells and the potential mechanism of antiproliferative effects of aspirin (ASA). Methods: The effects of aspirin on the stemness characteristics of KYSE-450 cells and KYSE-450 cells co-cultured with M2 macrophages (KYSE-450+ M2) were performed using spheroid formation assay. After treatment with aspirin, the expression of different chemokines, the core pluripotency gene Nanog and the stem cell marker CD90 in different cell groups were determined by real-time quantitative PCR, flow cytometry and Western blot. Results: The number of spheres formed in the ASA and KYSE-450+ M2 cell groups were 7.00±1.23 and 34.33±2.33, respectively, showing statistically significant difference compared with that of control group (14.50±2.33, all P<0.05). The number of spheres in KYSE-450+ M2+ ASA cell group were 20.67±2.33, which was significantly lower than that of KYSE-450+ M2 group (P<0.05). The expression levels of Nanog gene in control and ASA groups were 1.00 and 0.50±0.10, respectively, and the difference was statistically significant (P<0.05). Moreover, the expression of Nanog gene in cells of KYSE-450+ M2 group and M2+ KYSE-450+ ASA group was 1.74±0.13 and 1.43±0.05, showing statistically significant difference (P<0.05). When chemokine CCL2 was knocked down, the levels of Nanog gene in M2+ shCCL2-KYSE450+ ASA group and M2+ shCCL2-KYSE450 group were decreased to 1.22±0.11 and 1.17±0.08, respectively, and there was no statistically significant difference between them (P=0.69). Flow cytometry analyses showed that the expression levels of CD90 in control and ASA cells were (2.93±0.52)% and (1.30±0.17)%, respectively, and the difference was statistically significant (P<0.05). Moreover, the expression levels of CD90 in M2+ shCCL2-KYSE450 cells and M2+ shCCL2-KYSE450+ ASA cells were (4.07±0.12)% and (4.73±0.38)%, respectively, showing no statistically significant difference (P=0.17). Conclusions: Tumor-associated macrophages enhances the stemness of esophageal cancer cells, whereas aspirin attenuates the stemness by suppressing the expression of CCL2. Aspirin plays an anti-tumor effect in esophageal cancer cells.

Hyaluronic acid (HA) and cell-penetrating peptide (CPP) R6H4-SA modified artesunate nanostructured lipid carrier (HA-R6H4-NLC/ART) for anti-tumor therapy was prepared. The physicochemical properties and in vitro drug release of HA-R6H4-NLC/ART were evaluated, and the uptake and cytotoxicity of liver cancer HepG2 cells were studied. The results showed that HA-R6H4-NLC/ART was spherical like in appearance, and the average particle size was about 160 nm. In vitro release experiments showed that the drug delivery system had sustained release characteristics. Cell results showed that, in slightly acidic environment, pH sensitive CPP R6H4-SA mediated cellular uptake of nanoparticles was significantly higher than that of non-sensitive peptide R8-SA. Meanwhile, HA-R6H4-NLC/ART had a targeting effect on HepG2 cells, and the HA receptor saturation experiment showed that the endocytosis of HA-R6H4-NLC/ART was mediated by the HA receptor on the cell surface. As compared with the unmodified or R6H4-SA single modified group, HA and R6H4-SA co-modified HA-R6H4-NLC/ART significantly improved the cell uptake and had a stronger anti-tumor effect under the conditions of the slightly acid environment and hyaluronidase degradation. The above results showed that hyaluronic acid and CPP R6H4-SA co-modified artesunate nanostructured lipid carrier, which can effectively identify and penetrate the tumor cell membrane into the cell, is a potentially efficient targeting delivery system for anti-tumor drugs.

Particularly, target compounds exhibited significant cytotoxicity against drug-resistance cells MCF/Adr, which was worthy for further investigation.

To determine whether chloroquine (CQ), an often used inhibitor of late autophagy and autophagosome/lyosome fusion, can inhibit proliferation of renal carcinoma cells and investigate its effect on sunitinib (ST)-induced apoptosis.

Chemotherapy is the most important method for cancer treatment. However, chemotherapy induced nausea and vomiting (CINV) has a profound effect on patients. In recent years, there have been new antiemetic drugs, such as aprepitant. We review the curative effect of aprepitant with tropisetron and dexamethasone for prevention of nausea and vomiting in patients receiving Cisplatin chemotherapy.

Chemotherapy induced thrombocytopenia (CIT) is a common side-effect of chemotherapy in cancer patients, which lead to dose and cycle reduction or chemotherapy delay, or even the need of platelet transfusion. Therefore, CIT significantly increases the cost of treatment, reduces the efficacy of chemotherapy and the quality of life, and shortens the survival time of patients. The main treatments of CIT include transfusion of platelets, recombinant human thrombopoietin (rhTPO), and recombinant human interleukin-11 (rhIL-11). RhIL-11 is the first approved thrombocytopoietic cytokine. Interleukin-11 has been shown to be effective in the treatment of thrombocytopenia. RhTPO is a recombinant full-length glycosylated thrombopoietin, which is a ligand for c-Mpl protein. Several observations indicated that administration of rhTPO before and after chemotherapy might be beneficial to patients, which enhances platelet recovery and reduces thrombocytopenia after moderately myelosuppressive regimens. In recent years, the application of rhTPO in CIT treatment has dramatically changed the management and treatment plan of CIT. The China Society of Clinical Oncology (CSCO) published a consensus on CIT in 2014. Based on this, the expert committee updated "Consensus on clinical diagnosis, treatment and prevention management of chemotherapy induced thrombocytopenia in China (2018)" according to the recent literature and clinical research. The new evidence-based practice consensus for CIT aims to provide more reasonable diagnosis, treatment of prevention regimens for CIT patients to maintain the normal platelet counts.
