Chinese Journal of Cancer Research 2015年第6期27卷 538-544页

作者： Xue-Ning Yang Ze-Rui Zhao Wen-Zhao Zhong qiang Nie ri-qiang liao Song Dong Division of Surgery Department of Pulmonary Oncology Guangdong Lung Cancer Institute Guangdong General Hospital and Guangdong Academy of Medical Sciences

Background： We want to establish a lobe-specific mediastinal lymphadenectomy protocol for solitary pulmonary nodules （SPNs） in non-small cell lung cancer （NSCLC）. Methods： We retrospectively analyzed 401 patients with pathological diagnoses of NSCLC who underwent lobectomy, bilobectomy, or pneumonectomy with systematic lymphadenectomy from March 2004 to June 2011 in our hospital. All of the patients enrolled had a SPN preoperatively. Information about the primary tumor location, lymph node metastasis, and other baseline data were collected. Stepwise logistic regression was used to identify the key factors indicating non-regional mediastinal lymph node metastases （NRM）. Results： Of the primary tumors, 117, 39, 74, 104, and 67 were in the right upper lung （RUL）, right middle lung （RML）, right lower lung （RLL）, left upper lung （LUL）, and left lower lung （LLL）, respectively. Stepwise regression showed that #2,4, #10,11, and #10,11 as well as #7 was the key lymph node station for RUL, LUL, and lower lobes： #2,4 [odds ratio （OR）=28.000, 95% confidence interval （CI）： 2.917-268.790, P=0.004] for RUL, #10,11 （OR=31.667, 95% CI： 2.502-400.833, P=0.008） for LUL, #10,11 （OR=19.540, 95% CI： 4.217-90.541, P〈0.001） and #7 （OR=7.395, 95% CI： 1.586-34.484, P=0.011） for lower lobes, respectively. Patients with tumors 〉2 cm rarely had NRM without primary regional mediastinal involvement. Conclusions： With rigid consideration, a lobe-specific lymphadenectomy is feasible in practice. This protocol can be used when the lobe-specific key nodes are negative in intraoperative frozen sections, especially for NSCLC diagnosed as SPN 〈2 cm preoperatively.

Chinese Journal of Cancer Research 2015年第3期27卷 301-308页

作者： Xue-Ning Yang Ling Huang Yu Chen She-Juan An Xu-Chao Zhang ri-qiang liao Jian Su Yi-Long Wu Guangdong Lung Cancer Institute Guangdong Provincial Key Laboratory of Translational Medicine in Lung CancerGuangdong General Hospital& Guangdong Academy of Medical Sciences

Background： Available study revealed advanced tumors have a higher expression rate of MAGE-A3 gene which has a lot of single nucleotide polymorphism（SNP） loci with polymorphisms. This study aimed to analyze the allele frequency of SNP loci in MAGE-A3 gene and investigate the relationship between MAGE-A3 gene polymorphisms and clinical ***： Tumor samples of a cohort of 191 NSCLC patients were collected. EGFR m RNA expression were detected by q RT-PCR. SNPs in whole length of MAGE-A3 gene were detected by direct sequencing. Frequencies of the SNPs were correlated to gene expression, mutation status of EGFR and clinical ***： Sequencing analysis confirmed that allele frequencies of genotypes on SNP loci rs5970360, rs5925210, rs5970361, rs5925211 and rs35123853 were CC（0.681）/CT（0.319）, CC（0.660）/CG（0.340）, CC（0.681）/CA（0.319）, AA（0.984）/AT（0.016） and GG（1.000）/GA（0.000）, respectively, which were different from the frequencies and genotypes of MAGE-A3 in SNP database. Chi-square tests showed the EGFR mR NA expression level had significant correlation with the genotypes of SNP loci rs5970360 and rs5925210. But all frequencies of each MAGE-A3 SNPs were not found significantly different between EGFR mutant and wild type patients. MAGE-A3 gene polymorphisms had no significant effects on survival of NSCLC ***： Chinese patients with NSCLC had different SNP patterns of MAGE-A3 in comparison with those in international SNP database. These MAGE-A3 SNP loci might have not prognostic significance. MAGE-A3 SNP loci rs5970360 and rs5925210 might be predictive for EGFR m RNA expression levels and helpful to the selection of patients for epidermal growth factor receptor（EGFR） targeted immunotherapy.

Objective： To evaluate the efficacy and safety of nedaplatin/gemcitabine （NG） and carboplatin/gemcitabine （CG） in the management of untreated advanced non-small cell lung cancer （NSCLC）. Methods： Sixty-two patients with previously untreated advanced NSCLC were recruited between June 2006 and November 2007. Subjects were randomly assigned to the NG arm （n=30） and the CG arm （n=32）. Only patients （24 and 25 in the NG and CG arms, respectively） who completed 〉2 chemotherapy cycles were included in the data analysis. The primary outcome measure was the objective response rate （ORR）. The secondary outcome measures included progression-free survival （PFS）, overall survival （OS） and adverse events. Results： There were no statistically significant differences in the efficacy measures （ORR, P=0.305; median PFS, P=0.298, median OS, P=0.961） or in the major adverse events （grade 3/4 neutropenia, P=0.666; grade 3/4 anemia, P=0.263; grade 3/4 thrombocytopenia, P=0.222） between the two treatment arms. However, there was a trend towards higher ORR （37.5% vs. 24.0%）, longer PFS （6.0 vs. 5.0 months）, and less adverse events in the NG arm. Conclusion： NG regimen seems to be superior over CG regimen for advance NSCLS, but further investigation is needed to validate this superiority.

Analysis of the heat transfer in unsymmetrically heated triangular microchannels in slip flow regime

引用

Science China(Technological Sciences) 2004年第4期47卷 436-446页

作者： ZHU Xun liao qiang XIN Mingdao Institute of Engineering Thermophysics Chongqing University Chongqing 400044 China Institute of Engineering Thermophysics Chongqing University Chongqing 400044 China Institute of Engineering Thermophysics Chongqing University Chongqing 400044 China

A theoretical analysis of heat transfer characteristics is presented for the fully developed laminar flow of the incompressible gas in the triangular microchannels heated unsymmetrically with constant axial heat flux. Through solving the energy equation with temperature jump boundary conditions in slip flow regime by virtue of a computation- oriented method of the orthonormal function analysis, the dimensionless temperature profiles and the average Nusselt number for various thermal boundary conditions are obtained. The effects of Knudsen number, aspect ratio, and thermal boundary conditions on the heat transfer are discussed. The calculated results show that the orthonormal function method can be used to study the heat transfer characteristics of the unsymmetrically heated triangular microchannels. The average Nusselt number in triangular microchannels is lower for slip flow than for no-slip flow, and decreases with increasing Knudsen number. The aspect ratios and thermal boundary conditions of triangular microchannels have significant influences on the change of average Nusselt numbers with the increase in the Knudsen number. For the equilateral triangular microchannels, the decrease of the Nusselt number ratio due to temperature jump is smaller at large Knudsen number and larger at small Knudsen number on the boundary condition of bottom wall heated alone as compared with the one on the boundary condition of two heated hypotenuse walls. The correlations of the average Nusselt number with the Knudsen number for equilateral triangular microchannels are obtained.
