Nuclear receptors (NRs), which belong to a superfamily of ligand-dependent transcription factors, play essential roles in gene regulation to affect numerous physiological pathways. Twenty NR genes were identified in Nilaparvata lugens by using genomic, transcriptomic and GenBank databases, and categorized into NR0-NR6 subfamilies according to standard nomenclature. Among them, three NR geneswere classed into NR0, four into NR1, eight into NR2, one into NR3, one into NR4, two into NR5, and one into NR6, respectively. A phylogenetic tree of NRs from N. lugens and other representative species was constructed, which provided evolutionary insight into genetic distance. In order to investigate the NRs,whichwere induced by sulfoxaflor, time- and tissue-specific expression profiles of NR genes in fourth-instar nymphs were determined following LD50 sulfoxaflor treatment (0.28 ng/insect) and compared with control samples. NlUSP, NlE78, NlTLL, NlHR51, NlHR83, NlPNR and NlFTZ-F1 were highly expressed following 12–48 h of sulfoxaflor treatment. NlHR39 and NlDSF transcripts were detected in the head and the thorax, respectively. High-level and constitutive expression of NlHR3, NlTLL, NlHR83, NlFTZF1 and NlHR4 were found in the abdomen. Feeding of dsRNAs reduced the expression of NlHR3, NlUSP, NlTLL, NlHR83, NlPNR, NlFTZ-F1 and NlHR4 (35.48–49.77%) and caused significant nymph mortality (69.21–81.45%). These NRs, considered as insecticide targets, may play important function in sulfoxaflor detoxification.

<P><B>Abstract</B></P><P>A graph is half-arc-transitive if its automorphism group acts transitively on vertices and edges, but not on arcs. It is known that for a prime p there is no tetravalent half-arc-transitive graphs of order p or <SUP>p2</SUP>. Xu [M.Y. Xu, Half-transitive graphs of prime-cube order, J. Algebraic Combin. 1 (1992) 275–282] classified the tetravalent half-arc-transitive graphs of order <SUP>p3</SUP>. As a continuation, we classify in this paper the tetravalent half-arc-transitive graphs of order <SUP>p4</SUP>. It shows that there are exactly p−1 nonisomorphic connected tetravalent half-arc-transitive graphs of order <SUP>p4</SUP> for each odd prime p.</P>

Purpose: To investigate the efficacy and safety of Javanica oil emulsion injection (Yadanzi$^{(R)}$) combined with pemetrexed and platinum (PP) for treating patients with advanced lung cancer. Patients and Methods: From June 2011 to June 2013, we recruited 58 patients with advanced lung cancer, and divided them into two groups. Twenty eight patients received Yadanzi$^{(R)}$ (from ZheJiang Jiuxu Pharmaceutical Co., Ltd.) together with PP chemotherapy (combined group), while the others were given only PP chemotherapy (control group). After two cycles of treatment, efficacy and safety of treatment were evaluated. Results: The overall respnse rate [(CR+PR+SD)/(CR+PR+SD+PD)] of the combined group was higher than that of control group (89.7% vs. 86.2%, p>0.05). Regarding rate of life improvement, it was 82.8% in combined group, and 51.7% in the control group (p<0.05). In terms of side effects, leukopenia in combined group was less frequent than that in control group (p<0.05). More patients in the control group were found to suffer liver toxicity. Conclusions: Javanica oil emulsion injection combined with chemotherapy could be considered as a safe and effective regimen in treating patients with advanced lung adenocarcinoma. It can improve the quality of life and reduce the possibility of leukopenia. Further clinical trials with a large sample size should be conducted to confirm whether addition of Yadanzi$^{(R)}$ to chemotherapy could increase the response rate, reduce toxicity, enhance tolerability and improve quality of life for patients with advanced lung cancer.

Background: Pemetrexed (PEM) is effective in first-line treatment for patients with non-squamous non-small cell lung cancer (NSCLC). However there are currently no definitive determinants to certify which patients could benefit from PEM. To improve the efficacy of PEM combined with platinum as first-line therapy for advanced non-squamous NSCLC, we conducted this retrospective study to detect potential determinants of this regimen. Methods: We recruited 109 patients with advanced non-squamous NSCLC who received PEM with a platinum as first-line therapy from June 2006 to February 2013 in Jiangsu Cancer Hospital. Multiple variables (age, sex, smoking, degree of cell differentiation, hemoglobin, platinum drugs combined, positions of metastasis) were selected. Logistic regression analysis was used to analyse relationships between these variables and tumor response. Result: In univariate analysis, we found that age and platinum significantly influenced the results of PEM therapy (P<0.05). In multivariable analysis, no factors were independently significant. Conclusion: Our analysis did not suggest that the age, sex, metastasis of liver or other organs, hemoglobin, smoking history and pathological differentiation are associated with the response of PEM. We should conduct further analyses with larger sample size to reconfirm this issue.

Herein, a series of lasiokaurin derivatives were designed and synthesized. All the derivatives together with lasiokaurin and oridonin were tested for their antimicrobial and antiproliferative activity. Compound 16 showed the most promising antimicrobial activity with MICs of 2.0 and 1.0 lg/mL against Gram-Positive bacteria S. aureus and B. subtilis, respectively. All the synthetic lasiokaurin derivatives showed better antiproliferative activity than parent compound lasiokaurin 1. Compound 10 exhibited the strongest cytotoxicity with IC50 values of 0.47 and 0.20 lM against MGC-803 and CaEs-17 cells, accordingly. Moreover, it was shown to have potent antitumor activity in vivo in a murine model of MGC-803 gastric cancer. Preliminary SARs were also concluded based on obtained data. The apoptosis-inducing effects of 10 were further investigated using CaEs-17 cells. The results showed that lasiokaurin derivative 10 could induce apoptosis via mitochondria related pathway and arrest CaEs-17 cell cycle at S phase. Compound 10 could also affect apoptosisrelated proteins that was up-regulation of CDK2 and downregulation of ATM and cyclin A1.

Purpose: The current research was conducted to investigate the efficacy and safety of pemetrexed given continuously as a basement agent for first-, second- to third line chemotherapy of patients with metastatic lung adenocarcinoma. Patients and Methods: Patients with metastatic lung adenocarcinoma who were diagnosed in Jiangsu Cancer Hospital and Research Insitute, were enrolled. All received pemetrexed 500 $mg/m^2$ (intravenous; on day 1), and another chemotherapieutic agent every 3 weeks until disease progression, or intolerable toxicity. Then the patients were changed to a second line chemotherapy that was still based on pemetrexed 500 $mg/m^2$ and another chemotherapeutic agent differing from the first line example, until disease progression, or intolerable toxicity. When third line chemotherapy was needed, pemetrexed 500 $mg/m^2$ and another new chemotherapeutic agent were combined until disease progression. Evaluation of efficacy was conducted after two cycles of chemotherapy using the Response Evaluation Criteria for Solid Tumors. Toxicity was recorded according to NCI Criteria for Adverse Events version 3.0. Results: From January 2010 to September 2013, 15 patients were enrolled. Their median age was 56 years (range 43 to 77 years). Eight patients were male and 7 female. Five patients (33.3%) achieved PR, while 6 patients (40.0%) remained stable, no CR on first line; and 1 PR (7.7%), 5 stable (38.5%) were recorded when pemetrexed was ordered in second line; 5 patients (41.7%) were stable after pemetrexed was combined in third line; no complete response was observed. Main side effects were grade 1 to 2 neutrophil suppression and thrombocytopenia. Other toxicities included elevated transaminase and oral mucositis, but no treatment related death occurred. Conclusions: Pemetrexed continuously as a basement agent from first-, second- to third line chemotherapy is mildly effective in treating patients with metastatic lung adenocarcinoma with tolerable toxicity.

Objective: To observe efficacy and side effects, as well as the impact on quality of life, of Kanglaite$^{(R)}$ (Coix Seed Oil) injections combined with chemotherapy in the treatment of advanced gastric cancer patients. Method: A consecutive cohort of 60 patients were divided into two groups: the experimental group receiving Kanglaite$^{(R)}$ Injection combined with chemotherapy and the control group with chemotherapy alone. After more than two courses of treatment, efficacy, quality of life and side effects were evaluated. Results: The response rate and KPS score of experimental group were significantly improved as compared with those of the control group (P<0.05). In addition, gastrointestinal reactions and bone marrow suppression were significantly lower than in the control group (P<0.05). Conclusions: Kanglaite$^{(R)}$ Injection enhanced efficacy and reduced the side effects of chemotherapy, improving quality of life of gastric cancer patients; use of Kanglaite$^{(R)}$ injections deserves to be further investigated in randomized control clinical trails.

Objective: To compare expression level of serum tumor associated materials (TAM) with several conventional serum tumor biomarkers, eg., carcinoembryonic antigen (CEA), carbohydrate antigen19-9 (CA19-9), carbohydrate antigen 15-3 (CA15-3), alpha-fetoprotein(AFP), in selected solid tumors. Methods: Patients diagnosed histologically or cytologically with liver, breast, esophageal, gastric, colorectal or pancreatic cancers were enrolled into this study. After diagnosis, the level of TAM was determined by chemical colorimetry, and levels of conventional tumor markers was measured by chemiluminescence methods. Results: A total of 560 patients were enrolled into this study. No statistically significant difference was detected in TAM and the above mentioned tumor biomarkers in terms of their positivity and negativity ( P>0. 05). Conclusions: Detection of TAM in liver, breast, esophageal, gastric, colorectal, and pancreatic cancer patients demonstrates a good accordance with CEA, CA199, CA153, and AFP, thus suggesting that further study is warranted to verify whether TAM could be a surrogate for these conventional biomarkers.
