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.

Lu, Yan-Yan,Huang, Xin-En,Cao, Jie,Xu, Xia,Wu, Xue-Yan,Liu, Jin,Xiang, Jin,Xu, Lin Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.8

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.

Clinical Observations on Associations Between the UGT1A1 Genotype and Severe Toxicity of Irinotecan

Lu, Yan-Yan,Huang, Xin-En,Wu, Xue-Yan,Cao, Jie,Liu, Jin,Wang, Lin,Xiang, Jin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.7

Background: Severe toxicity is commonly observed in cancer patients receiving irinotecan (CPT-11) UDPglucuronosyltransferase1A1 (UGT1A1) catalyzes the glucuronidation of the active metabolite SN-38 but the relationship between UGT1A1 and severe toxicity remains unclear. Our study aimed to assess this point to guide clinical use of CPT-11. Materials and Methods: 89 cancer patients with advanced disease received CPT-11-based chemotherapy for at least two cycles. Toxicity, including GI and hematologic toxicity was recorded in detail and UGT1A1 variants were genotyped. Regression analysis was used to analyse relationships between these variables and tumor response. Results: The prevalence of grade III-IV diarrhea was 10.1%, this being more common in patients with the TA 6/7 genotype (5 of 22 patients, 22.7%) (p<0.05). The prevalence of grade III-IV neutropenia was 13.4%and also highest in patients with the TA 6/7 genotype (4 of 22 patients; 18.2%) but without significance (p>0.05). The retreatment total bilirubin levels were significantly higher in TA6/7 patients (mean, $12.75{\mu}mol/L$) with compared to TA6/6 (mean, $9.92{\mu}mol/L$) with p<0.05. Conclusions: Our study support the conclusion that patients with a $UGT1A1^*28$ allele (s) will suffer an increased risk of severe irinotecan-induced diarrhea, whether with mid-or low-dosage. However, the $UGT1A1^*28$ allele (s) did not increase severe neutropenia. Higher serum total bilirubin is an indication that patients UGT1A1 genotype is not wild-type, with significance for clinic usage of CPT-11.

Weights-adjust Notification Protocol of Cooperative Spectrum Sensing for Ship Ad-hoc Network

Yan Huang,Xin Su,KyungHi Chang 한국통신학회 2013 한국통신학회 학술대회논문집 Vol.2013 No.1

The ship ad-hoc network (SANET) extends the coverage of the high date rate terrestrial communications to the ships with reduced cost in maritime communications. Cognitive radio (CR) technology can help SANET to utilize the spectrum efficiently by exploiting the existing wireless spectrum opportunistically. However, hidden primary node problem decreases the performance of CR-based SANET. In this paper, we compare three traditional cooperative spectrum sensing (CSS) technologies on their performance for solving the hidden primary node problem. And to improve false alarm performance, a weights-adjust notification protocol (WANP) is proposed.

Objective: To assess the safety and effectiveness of thalidomide (produced by CHANGZHOU PHARMACEUTICAL FACTORY CO.LTD) combined with chemotherapy in treating patients with advanced colorectal cancer. Method: A consecutive cohort of pretreated patients with advanced colorectal cancer were treated with thalidomide combined with chemotherapy. And chemotherapy for patients with advanced colorectal cancer were administered according to the condition of patients. Thalidomide was orally administered at a dosage of 50mg/day to 150mg/day before sleeping for at least 14 days. After at least 14 days of treatment, safety and side effects were evaluated. Results: There were 12 female and 3 male patients with advanced cancer recruited into this study, including 9 patients with colon, 6 patients with rectal cancer. The median age of patients was 57(41-82) years. Partial response was observed in 2 patients (2/15), and stable disease in 3 patients(3/15). Incidences of Grade 1 to 2 myelosuppression was observed in 1/15 patients, and Grade 1 to 2 elevation of hepatic enzyme was recorded in 1/15 patients. Adverse effects on the gastrointestinal tract were documented in 1/15 patients, and were Grade 1. No Grade 3-4 toxicities were diagnosed. No treatment related death was found. Conclusions: Thalidomide combined with chemotherapy was safe and mildly effective in treating patients with advanced colorectal cancer. However, further study should be conducted to clarify the effectiveness of this combination.

Ultimate strength of rectangular concrete-filled steel tubular (CFT) stub columns under axial compression

Yan-sheng Huang,Yue-Ling Long,Jian Cai 국제구조공학회 2008 Steel and Composite Structures, An International J Vol.8 No.2

A method is proposed to estimate the ultimate strength of rectangular concrete-filled steel tubular (CFT) stub columns under axial compression. The ultimate strength of concrete core is determined by using the conception of the effective lateral confining pressure and a failure criterion of concrete under true triaxial compression, which takes into account the difference between the lateral confining pressure provided by the broad faces of the steel tube and that provided by the narrow faces of the steel tube. The longitudinal steel strength of broad faces and that of the narrow faces of the steel tube are calculated respectively due to that buckling tends to occur earlier and more extensively on the broader faces. Finally, the proposed method is verified with experimental results. Corresponding values of ultimate strength calculated by ACI (2005), AISC (1999) and GJB4142-2000 are given respectively for comparison. It is found from comparison that the proposed method shows a good agreement with the experimental results.

Yan Fei Zhu,Chang Hong Chen,Ying Huang,Zhaohui Huang,Yao Yao,Leon M. Keer 국제구조공학회 2021 Steel and Composite Structures, An International J Vol.40 No.4

A component-based method for the estimation of the posttensioned (PT) steel frame against progressive collapse is proposed and presented in the current paper. A mechanical model of PT steel connections is developed and benchmarked with experimental data of a PT beam-column substructure from literature. The developd mechanical models of four PT connections are able to capture the initial elastic stiffness, decompression load, and residual stiffness under lateral loading. Then, analysis of a reduced-scale three-storey two-bay PT steel frame is carried out with sufficient accuracy by incorporating the proposed joint model into the frame analysis. The proposed method is then applied to assessing progressive collapse of a one-storey two-bay PT frame under middle column removal scenario, and is verified against existing experimental and ANSYS finite element results. Three resistance mechanism for progressive collapse of the PT frame are evaluated, which consists of angle flexural mechanism, beam compression arching action and strand tensile catenary action. Finally, parameter analyses of the PT frames are conducted to investigate the effects of the connection details on the behavior and resistance of progressive collapse. The proposed model can be used to predict the quasi-static behavior of PT frames under monotonic vertical loading conditions with satisfactory accuracy.

Yan-Jin Huang,Monica Parry,Ying Zeng,Yan Luo,Jing Yang,Guo-Ping He 한국간호과학회 2017 Asian Nursing Research Vol.11 No.3

Purpose: Early detection and management of coronary heart disease (CHD) are embedded into many community health service and primary care practices in western countries. The Framingham CHD risk score has been used to predict CHD and mortality for nearly 20 years, and it has predicted CHD event risk accurately in multiethnic populations. The aim of this study was to access the effect of a 6-month community-based intervention on CHD risk in individuals at high risk. Methods: A randomized controlled trial of individuals with a high 10-year CHD risk were recruited from two communities in China. Individuals in the intervention group (n ¼ 53) received a 3-month group education and a 3-month coaching session. Physical examination and self-report questionnaires were used to collect both pre- and postintervention data on blood pressure, glucose, cholesterol, body mass index, smoking, depression, and health-related quality of life (HRQoL). Results: A total of 102 participants (85.0%) completed the 6-month study. Compared with the usual care group, the intervention group had a 5 mmHg greater reduction in systolic blood pressure (t = 2.01, p = .047), larger declines in glucose (t = 2.49, p = .015), cholesterol (t = 2.44, p = .017), body mass index (t = 2.58, p = .011), and depression (t = 2.05, p = .043), and better reports of HRQoL (t = 3.36, p = .001). No significant group differences in smoking behaviors were reported. Conclusion: A 6-month community-based intervention in a CHD high-risk population improved diseaserelated risk factors, depression, and HRQoL. Results provide preliminary evidence for primary prevention of cardiovascular disease risk in a community high-risk population.
