  • Objective: To investigate the effects of $CD4^+$, IL17 and Foxp3 expression on prognosis of operable non-small cell lung cancer (NSCLC) with different pTNM stages. Methods: Expression of $CD4^+$, IL17 and Foxp3 in 102 cases of NSCLC tissues and adjacent cancer tissues was detected by immunohistochemistry and associations with prognosis with different pTNM stages were analyzed. The Chi-square test was used to compare count data. Survival differences were evaluated by Kaplan-Meier single factor analysis and the COX regression model was used to analyze the relationship between influential factors and the disease prognosis. The significance level was ${\alpha}$=0.05. Results: Expression of CD4, IL-17 and Foxp3 significantly varied in different pTNM stages of NSCLC tissues (P < 0.05). The same was true for CD4 expression (P < 0.05). The median survival time (MST) in the positive CD4 expression group was evidently higher than that in the negative group (25.8/23.9 months). Compared with stage III, the MST difference of stages I and II in the positive CD4 expression group were statistically significant (P < 0.05). The MST in positive IL-17 and Foxp3 expression groups was obviously lower than that in the corresponding negative group (P < 0.05) (25.6/35.1 months and 24/35.3 months, respectively). There was a significant difference of MST between any two of three stages of positive IL-17 expression group (P < 0.05), and it was the same with positive Foxp3 expression group. TNM stage, negative CD4 expression, and positive IL-17 and Foxp3 expression were the main risk factors for the prognosis of NSCLC. Conclusion: Surgical prognosis of NSCLC can be better assessed by the combination of clinical staging and expression of IL17 and Foxp3.

  • Background: The aim of this study was to evaluate how CYP2C19 affects icotinib and metabolite' exposure, and to determine whether the exposure and EGFR genotype influences survival time, tumor metastasis and adverse drug reactions. Materials and Methods: 274 NSCLC patients who accepted 125mg icotinib/t.i.d. were chosen from a phase III study. Blood samples were obtained in $672^{nd}$ ($4^{th}$ week) and $1,680^{th}$ hours ($10^{th}$ week), and plasma was used to quantify the concentration of icotinib and blood cells were sampled to check the genotypes. Clinical data were also collected at the same time, including EGFR genotypes. Plasma concentrations were assessed by HPLC-MS/MS and genotype by sequencing. All data were analyzed through SPSS 17.0 and SAS 9.2. Results: CYP 2C19 genotypes affected bio-transformation from icotinib to M24 and M26, especially in poor-metabolisers. Higher icotinib concentrations (>1000 ng/mL) not only increased patient PFS and OS but also reduced tumor metastasis. Patients with mutant EGFR experienced a higher median PFS and OS (234 and 627 days), especially those with the 19del genotype demonstrating higher PR ratio. Patients who suffered grade II skin toxicity had a higher icotinib exposure than those with grade I skin toxicity or no adverse effects. Liver toxic reactions might occur in patients with greater M20 and M23 plasma concentrations. Conclusions: CYP2C19 polymorphisms significantly affect icotinib, M24 and M26 exposure. Patients with mutant EGFR genotype and higher icotinib concentration might have increased PFS and OS and lower tumor metastasis. Liver ADR events and serious skin effects might be respectively induced by greater M20, M23 and icotinib concentrations.

  • Objective: To make the clinical evaluation of a solid-state human papillomavirus (HPV) sampling medium in combination with an economical HPV testing method ($careHPV^{TM}$) for cervical cancer screening. Methods: 396 women aged 25-65 years were enrolled for cervical cancer screening, and four samples were collected. Two samples were collected by woman themselves, among which one was stored in DCM preservative solution (called "liquid sample") and the other was applied on the Whatman Indicating FTA $Elute^{(R)}$ card (FTA card). Another two samples were collected by physician and stored in DCM preservative solution and FTA card, respectively. All the samples were detected by $careHPV^{TM}$ test. All the women were administered a colposcopy examination, and biopsies were taken for pathological confirmation if necessary. Results: FTA card demonstrated a comparable sensitivity of detecting high grade Cervical Intraepithelial Neoplasia (CIN) with the liquid sample carrier for self and physician-sampling, but showed a higher specificity than that of liquid sample carrier for self-sampling (FTA vs Liquid: 79.0% vs 71.6%, p=0.02). Generally, the FTA card had a comparable accuracy with that of Liquid-based medium by different sampling operators, with an area under the curve of 0.807 for physician &FTA, 0.781 for physician &Liquid, 0.728 for self & FTA, and 0.733 for self &Liquid (p>0.05). Conclusions: FTA card is a promising sample carrier for cervical cancer screening. With appropriate education programmes and further optimization of the experimental workflow, FTA card based self-collection in combination with centralized $careHPV^{TM}$ testing can help expand the coverage of cervical cancer screening in low-resource areas.

  • Over-expression of de novo lipogenesis (DNL) genes is associated with the prognosis of various types of cancers. However, the effects of single nucleotide polymorphisms (SNPs) in these genes on recurrence and survival of non-small cell lung cancer (NSCLC) patients after surgery are still unknown. In this study, a total of 500 NSCLC patients who underwent surgery treatment were included. Eight SNPs in 3 genes (ACACA, FASN and ACLY) of the DNL pathway were examined using the Sequenom iPLEX genotyping system. Multivariate Cox proportional hazards regression and Kaplan-Meier curves were used to analyze the association of SNPs with patient survival and tumour recurrence. We found that two SNPs in the FASN gene were significantly associated with the recurrence of NSCLC. SNP rs4246444 had a significant association with lung cancer recurrence under additive model (hazard ratio [HR], 0.82; 95% confidence interval [95%CI], 0.67-1.00; p=0.05). Under the dominant model, rs4485435 exhibited a significant association with recurrence (HR, 0.75; 95%CI, 0.56-1.01; p=0.05). Additionally, SNP rs9912300 in ACLY gene was significantly associated with overall survival in lung cancer patients (HR, 1.41; 95%CI, 1.02-1.94, p=0.04) under the dominant model. Further cumulative effect analysis showed moderate dose-dependent effects of unfavorable SNPs on both survival and recurrence. Our data suggest that the SNPs in DNL genes may serve as independent prognostic markers for NSCLC patients after surgery.

  • Objective: To evaluate clinical efficacy of a dose escalating schedule of paclitaxel concurrent with radiotherapy in treating patients with locally advanced non-small cell lung (NSCLC). Methods: Patients with locally advanced NSCLC were treated with conventional fractionated radiotherapy or three dimensional conformal radiotherapy (3 DCRT), concurrently with a dose escalating schedule of paclitaxel. All patients were divided into three groups, A with paclitaxel $30mg/m^2$, B with paclitaxel $60mg/m^2$ and C with paclitaxel $90mg/m^2$. Paclitaxel was repeated every week for a total of 4 or 6 weeks. Results: Among 109 patients, response rates were 68.8%, 71.1% and 71.8% (p>0.05) for group A (n=32), B (n=38), and C (n=39) respectively. Accordingly, disease control rates were 81.3%, 81.6% and 82.1% (p>0.05). Progression-free survival time was $8.0{\pm}5.0$ months, $11.6{\pm}6.1$ months, and $14.8{\pm}7.9$ months (p<0.05), respectively. Overall survival time was $15.4{\pm}7.6$ months, $18.2{\pm}8.0$ months, and $22.0{\pm}7.6$ months (p<0.05), one-year survival rates were 62.5%, 73.1% and 90.0% (p>0.05) and two-year survival rates were 31.3%, 38.5% and 50.0% (p<0.05). Main side-effects were bone marrow suppression, radiation related esophagitis and gastrointestinal reaction. Conclusion: In treating patients with NSCLC, concurrent chemoradiotherapy with paclitaxel improves early response compared with conventional fractionated radiotherapy or 3 DCRT. The survival rate was improved with the addition of paclitaxel, but there was an increase in adverse reactions when the dose of paclitaxel was increased.

  • Background: Lymph node metastasis is believed to be a dependent negative prognostic factor of esophageal cancer. To explore detection methods with high sensitivity and accuracy for metastases to regional and distant lymph nodes in the clinic is of great significance. This study focused on clinical application of FDG PET/CT and contrast-enhanced multiple-slice helical computed tomography (MSCT) in lymph node staging of esophageal cancer. Materials and Methods: One hundred and fifteen cases were examined with enhanced 64-slice-MSCT scan, and FDG PET/CT imaging was conducted for neck, chest and upper abdomen within one week. The primary lesion, location and numbers of metastatic lymph nodes were observed. Surgery was performed within one week after FDG PET/CT detection. All resected lesions were confirmed histopathologically as the gold standard. Comparative analysis of the sensitivity, specificity, and accuracy based on FDG PET/CT and MSCT was conducted. Results: There were 946 lymph node groups resected during surgery from 115 patients, and 221 were confirmed to have metastasis pathologically. The sensitivity, specificity, accuracy of FDG PET/CT in detecting lymph node metastasis were 74.7%, 97.2% and 92.0%, while with MSCT they were 64.7%, 96.4%, and 89.0%, respectively. A significance difference was observed in sensitivity (p=0.030), but not the others (p>0.05). The accuracy of FDG PET/CT in detecting regional lymph node with or without metastasis were 91.9%, as compared to 89.4% for MSCT, while FDG PET/CT and MSCT values for detecting distant lymph node with or without metastasis were 94.4% and 94.7%. No significant difference was observed for either regional or distant lymph node metastasis. Additionally, for detecting para-esophageal lymph nodes metastasis, the sensitivity of FDG PET/CT was 72%, compared with 54.7% for MSCT (p=0.029). Conclusions: FDG PET/CT is more sensitive than MSCT in detecting lymph node metastasis, especially for para-esophageal lymph nodes in esophageal cancer cases, although no significant difference was observed between FDG PET/CT and MSCT in detecting both regional and distant lymph node metastasis. However, enhanced MSCT was found to be of great value in distinguishing false negative metastatic lymph nodes from FDG PET/CT. The combination of FDG PET/CT with MSCT should improve the accuracy in lymph node metastasis staging of esophageal cancer.

  • One of the goals of tumor immunotherapy is to generate immune cells with potent anti-tumor activity through in vitro techniques using peripheral blood collected from patients. However, cancer patients generally have poor immunological function. Thus using patient T cells, which have reduced in vitro proliferative capabilities and less tumor cell killing activity to generate lymphokine-activated killer (LAK) cells, fails to achieve optimal clinical efficacy. Interleukin-2 (IL-2) is a potent activating cytokine for both T cells and natural killer cells. Thus, this study aimed to identify optimal donors for allogeneic LAK cell immunotherapy based on single nucleotide polymorphisms (SNP) in the IL-2 and IL-2R genes. IL-2 and IL-2R SNPs were analyzed using HRM-PCR. LAK cells were derived from peripheral blood mononuclear cells by culturing with IL-2. The frequency and tumor-killing activity of LAK cells in each group were analyzed by flow cytometry and tumor cell killing assays, respectively. Regarding polymorphisms at IL-2-330 (rs2069762) T/G, LAK cells from GG donors had significantly greater proliferation, tumor-killing activity, and IFN-${\gamma}$ production than LAK cells from TT donors (P<0.05). Regarding polymorphisms at IL-2R rs2104286 A/G, LAK cell proliferation and tumor cell killing were significantly greater in LAK cells from AA donors than GG donors (P<0.05). These data suggest that either IL-2-330(rs2069762)T/G GG donors or IL-2R rs2104286 A/G AA donors are excellent candidates for allogeneic LAK cell immunotherapy.

  • 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.

  • In cervical cancer, one of the most common malignant tumors in women worldwide, miR-126 has been reported to exhibit decreased expression. However, its role in cervical cancer cell proliferation and drug sensitivity has remained relatively unexplored. Here, we compared the expression of miR-126 in cervical cancer tissues (n = 20) with that in normal cervical tissue (n = 20) using quantitative RT-PCR. The viability of Siha cervical cancer cells was further measured by MTT assay after transfection with miR-126 mimic (Siha-miR-126 mimic) or microRNA mimic negative control (Siha-miR mimic NC) and after treatment with various concentrations of bleomycin (BLM). IC50s were calculated, and the survival rates (SRs) of Siha cells were calculated. miR-126 expression in cervical cancer tissue was significantly decreased compared with that in normal cervical tissue (P < 0.01). The relative SRs of Siha-miR-126 mimic cells were also significantly decreased compared with those of Siha-miR mimic NC cells at 24-96 h after transfection. The IC50 of BLM in Siha-miR-126 mimic cells ($50.3{\pm}2.02{\mu}g/mL$) was decreased compared with that in Siha-miR mimic NC cells ($70.5{\pm}4.33{\mu}g/mL$) at 48 h after transfection (P < 0.05). Finally, the SRs of Siha-miR-126 mimic cells were significantly lower than those of SihamiR mimic NC cells after cultured in medium containing 40 ${\mu}g/mL$ BLM for 24-96 h (P < 0.05). These results suggest that miR-126 is expressed at low levels in cervical cancer. Upregulation of miR-126 inhibited cervical cancer cell proliferation and enhanced the sensitivity to BLM. Thus, miR-126 may represent a novel approach to cervical cancer treatment.

  • This researcher has sorted out the development process of death aesthetics contained in human art through advanced research. This research is a follow-up study of related research, which studies the aesthetic meaning of death in Alexander McQueen's fashion works. This study first classifies the aesthetic characteristics of death, and then analyzes and sorts out the aesthetics of death in Alexander McQueen's clothing works based on this. The results of this study are as follows: first, the aesthetic manifestations of death are divided into three categories: reproducibility, symbolic and religious. Among them, the representation of reproducibility includes the representation of real objects and the representation of virtual objects, and the symbolic performance includes two types of external performance and internal performance. Second, in Alexander McQueen's works, the reproducibility of death was mainly reflected by virtual stage scenes and costumes. Thirdly, the symbolic death is not only reflected in the skeletons and blood etc. directly related to the death of the body, but also in the various emotions and psychological states caused by the death. Fourth, the religious nature of death was represented in Alexander McQueen's works through such representative things as crosses and religious stories.
