Abstract
FAK is a nonreceptor intracellular tyrosine kinase which plays an important biological function. Many studies have found that FAK is overexpressed in many human cancer cell lines, which promotes tumor cell growth by controlling cell adhesion, migration, proliferation, and survival. Therefore, targeting FAK is considered to be a promising cancer therapy with small molecules. Many FAK inhibitors have been reported as anticancer agents with various mechanisms. Currently, six FAK inhibitors, including GSK-2256098 (Phase I), VS-6063 (Phase II), CEP-37440 (Phase I), VS-6062 (Phase I), VS-4718 (Phase I), and BI-853520 (Phase I) are undergoing clinical trials in different phases. Up to now, there have been many novel FAK inhibitors with anticancer activity reported by different research groups. In addition, FAK degraders have been successfully developed through “proteolysis targeting chimera” (PROTAC) technology, opening up a new way for FAK-targeted therapy. In this paper, the structure and biological function of FAK are reviewed, and we summarize the design, chemical types, and activity of FAK inhibitors according to the development of FAK drugs, which provided the reference for the discovery of new anticancer agents.

Abstract
Pesticide residues have become a healthy threaten of human beings. Among the pesticides, many of them have neurotoxicity. Extracellular Regulated Protein Kinases (ERK) pathway is an important signaling pathway that regulates a variety of downstream progress. In this work, peach (PRUNUS persica) and cherry (PRUNUS cerasus) were sampled from over 300 plantations in China and assessed for the residue risk. In mechanism studies, high-risk pesticide Avermectin showed a high activity inhibiting three neurotoxicity models, SH-SY5Y, PC-12 and SK-N-SH cells. At protein levels, ERK pathway proteins and their downstream proteins were obviously down-regulated. Moreover, the effects of low-dose Avermectin can be accumulated at protein levels in the low-dose long-term chronic toxicology detection.

Abstract
Chalcone is a common scaffold found in many biologically active compounds. The chalcone scaffold was also frequently utilized to design novel anticancer agents with potent biological efficacy. Aiming to continue the research of effective chalcone derivatives to treat cancers with potent anticancer activity, fourteen amino chalcone derivatives were designed and synthesized. The antiproliferative activity of amino chalcone derivatives was studied in vitro and 5-Fu as a control group. Some of the compounds showed moderate to good activity against three human cancer cells (MGC-803, HCT-116 and MCF-7 cells) and compound 13e displayed the best antiproliferative activity against MGC-803 cells, HCT-116 cells and MCF-7 cells with IC50 values of 1.52 μM (MGC-803), 1.83 μM (HCT-116) and 2.54 μM (MCF-7), respectively which was more potent than the positive control (5-Fu). Further mechanism studies were explored. The results of cell colony formatting assay suggested compound 10e inhibited the colony formation of MGC-803 cells. DAPI fluorescent staining and flow cytometry assay showed compound 13e induced MGC-803 cells apoptosis. Western blotting experiment indicated compound 13e induced cell apoptosis via the extrinsic/intrinsic apoptosis pathway in MGC-803 cells. Therefore, compound 13e might be a valuable lead compound as antiproliferative agents and amino chalcone derivatives worth further effort to improve amino chalcone derivatives' potency.

Abstract
Background To date, there is no validated whole grain assessment tool for children in any Southeast Asian countries. Hence, there is a need for a valid tool to assess whole grain intake among Malaysian children. This study aimed to develop, validate and test the reproducibility of a food frequency questionnaire (FFQ) in estimating whole grain intake among Malaysian children. Methods A total of 392 children participated in the FFQ development and 112 children aged 9–12 years participated in the validation phase; with a subsample of 50 children participating in the reproducibility phase. Three-day diet record (3DR) as the reference method in validation phase. Spearman correlations, mean difference, Bland-Altman plot and cross-classification analyses were used to assess validity. The reproducibility was tested through a repeat administration of the FFQ, with 1 month time interval. Reproducibility analyses involved intra-class correlation coefficient (ICC), Cronbach’s alpha and cross-classification analyses. Results The FFQ consisted of 156 whole grain food items from six food groups. Mean intake of whole grain in FFQ1 and 3DR were correlated well (r = 0.732), demonstrated good acceptance of the FFQ. Bland Altman plots showed relatively good agreement for both the dietary methods. Cross-classification of whole grain intake between the two methods showed that < 9.9% of children were grossly misclassified. Outcomes from ICC (0.989) and Cronbach’s alpha (0.995) demonstrated excellent reliability. All the children were classified in the same or adjacent quartile of whole grain intake. Conclusions Overall, the findings support the validity of the developed FFQ to appropriately estimate the whole grain intake in Malaysian children. This validated FFQ will be a valuable tool for future studies, to analyses the impact of whole grain consumption with disease relationship among Malaysian schoolchildren.

Abstract
OBJECTIVE To investigate the feasibility of inducing adipose-derived stem cells (ADSCs) to nucleus pulposus cells (NPCs). MATERIALS AND METHODS ADSCs were isolated from rabbit while NPCs were isolated from an allogeneic rabbit. NPCs were co-cultured with the 3rd generation ADSCs in co-cultured system. Only NPCs were cultured in single culturing group. Through the collagen type II collagen immunohistochemistry, we observed NPCs and then identify NPC. Proteoglycan messenger RNA (mRNA) and collagen type II mRNA level were measured by real-time polymerase chain reaction. RESULTS In two group cells, collagen type II collagen were detected by immunohistochemistry. The amount of proteoglycan mRNA and collagen type II mRNA was both significantly higher in co-cultured group than in single cultured group. CONCLUSIONS In some condition, ADSCs have the potency to differentiate toward nucleus pulposus-like cells. ADSCs are better seed cells for tissue engineering of artificial nucleus pulposus.

Abstract
We investigated inhibition of Moloney leukemia virus 10 (MOV10) upon xenotropic murine leukemia virus-related virus (XMRV) and made a preliminary study of the mechanism of action. Using transfection, infection, western blotting and real-time polymerase chain reaction, we found that MOV10 inhibited XMRV replication. Using MOV10 overexpressed in viral producer cells, MOV10 was shown to reduce the infectivity of XMRV. MOV10 could be incorporated into XMRV, suggesting that MOV10 could undergo encapsidation by XMRV during viral assembly. MOV10 could also restrict the DNA production of XMRV in target cells. We found that the putative RNA-helicase domain of MOV10 maintained most of its XMRV inhibition. These results suggest that MOV10 could be required during the retroviral lifecycle. Perturbation of MOV10 disrupts the generation of infectious viral particles, suggesting that MOV10 has broad antiretroviral activity. Hence, MOV10 could be actively involved in host defense against retroviral infection.

Abstract
BST-2 plays an important role in host innate immune response via inhibiting the release of HIV-1. HIV-1 accessory protein Vpu can interact with BST-2 through its transmembrane domains, degrade BST-2, and decrease BST-2 that are transported to the cell surface, thus anti-virus function of BST-2 is antagonized. In our study, we constructed plasmid RB connecting Rluc to the N-termimal of BST-2, and plasmid VE connecting EYFP to the C-terminal of Vpu. The two fusion proteins were co-expressed in 293 cells, and the interaction between the two proteins was detected via BRET method. And we further established a stable 293 cell line of dual-expression. By using BRET method, and the interaction between BST-2 and Vpu transmembrane domain as the target, a high-throughput screening assay was created that was expected to seek novel interaction inhibitors.

Abstract
Recently, BST-2 has been identified as an effective cellular factor that prevents the release of human immunodeficiency virus type 1 and other enveloped viruses by tethering virus particles to the cell surface. Here, we showed that the production of HIV-1 virus-like particles was markedly inhibited by BST-2. Both the transient and stable expressing of BST-2 had the same function and Vpu rescued the release of HIV-1 VLP in the presence of human BST-2. Consistent with a direct tethering mechanism, we confirmed that proteolysis releases restricted virions and further showed that this removed the ectodomain of BST-2 from the cell surface.

Abstract
OBJECTIVE To study the inhibitory effect of Danggui Buxue Tang (DBT), a compound traditional Chinese herbal medicine for supplementing blood, on tumor growth in tumor-bearing mice after inoculation of EL-4 cells, and its immune mechanism as well as its synergic effect in reducing toxicity of cytoxan (CTX). METHODS Experiment was carried out in tumor-bearing mice after inoculation of EL-4 cells. The mice were randomly divided into four groups after 7 days of the inoculation: untreated group, DBT-treated group [24 g/(kg x d)], CTX-treated group [7.5 mg/(kg x d)] and DBT plus CTX-treated group, with another ten normal mice as control. Inhibitory rate of tumor growth, survival time, immune function and variability of blood cells were measured in the mice during the experiment. RESULTS After treatment of relevant interventions for 15 days, the tumor in the DBT-treated group, CTX-treated group and DBT plus CTX-treated group grew slower than the untreated group (P<0.05). Murine survival time in the DBT-treated group, CTX-treated group and DBT plus CTX-treated group was lengthened as compared with that in the untreated group (P<0.05). Compared with the untreated group, all kinds of immune indexes in the DBT-treated group and DBT plus CTX-treated group were significantly improved (P<0.05), while the immune indexes in the CTX-treated group were decreased (P<0.05). Compared with the CTX-treated group, all kinds of immune indexes in the DBT plus CTX-treated group were significantly improved (P<0.05). CONCLUSIONS DBT can enhance the immune function in tumor-bearing mice and the inhibitory effect of DBT on tumor growth is related to the enhanced immune response. DBT can also increase the therapeutic effects and reduce the side effects of CTX.

Abstract
The study was carried out in 1985-86 in Hainan Island where Plasmodium falciparum is resistant to chloroquine. Fifty cases of falciparum malaria were treated with 1800 mg amodiaquine for 3 days: the cure rate was 65.3%, and the mean time to clear fever and asexual parasitaemia was 30.7 and 60.3 hours, respectively; 34.7% of cases showed RI or RII recrudescence, and one patient's temperature did not come down to normal within 7 days.Twenty-one cases were treated with sulfadoxine-pyrimethamine (1500 mg and 75 mg, respectively): 19 were cured, I showed RI and another had an S or RI response; the mean time for fever control was 56.1 hours.Fifty cases were treated with amodiaquine plus sulfadoxine and 49 received amodiaquine plus sulfadoxine-pyrimethamine: the cure rate was 97.9% and 100%, respectively; the mean time for fever clearance was 25.0 and 25.7 hours and for parasite clearance 57.1 and 52.8 hours, respectively. These drug combinations gave much better results for cure and for symptom control than amodiaquine or sulfadoxine-pyrimethamine alone, and may be considered for treatment of chloroquine-resistant falciparum malaria.
