Abstract
Purpose We investigated the correlation between the number of examined lymph nodes (ELNs) and correct staging and long-term survival in non-small-cell lung cancer (NSCLC) by using large databases and determined the minimal threshold for the ELN count. Methods Data from a Chinese multi-institutional registry and the US SEER database on stage I to IIIA resected NSCLC (2001 to 2008) were analyzed for the relationship between the ELN count and stage migration and overall survival (OS) by using multivariable models. The series of the mean positive LNs, odds ratios (ORs), and hazard ratios (HRs) were fitted with a LOWESS smoother, and the structural break points were determined by Chow test. The selected cut point was validated with the SEER 2009 cohort. Results Although the distribution of ELN count differed between the Chinese registry (n = 5,706) and the SEER database (n = 38,806; median, 15 versus seven, respectively), both cohorts exhibited significantly proportional increases from N0 to N1 and N2 disease (SEER OR, 1.038; China OR, 1.012; both P < .001) and serial improvements in OS (N0 disease: SEER HR, 0.986; China HR, 0.981; both P < .001; N1 and N2 disease: SEER HR, 0.989; China HR, 0.984; both P < .001) as the ELN count increased after controlling for confounders. Cut point analysis showed a threshold ELN count of 16 in patients with declared node-negative disease, which were examined in the derivation cohorts (SEER 2001 to 2008 HR, 0.830; China HR, 0.738) and validated in the SEER 2009 cohort (HR, 0.837). Conclusion A greater number of ELNs is associated with more-accurate node staging and better long-term survival of resected NSCLC. We recommend 16 ELNs as the cut point for evaluating the quality of LN examination or prognostic stratification postoperatively for patients with declared node-negative disease.

Abstract
BACKGROUND Small cell lung cancer (SCLC) is a subtype of lung cancer with poor prognosis. In this study, we aimed to build a nomogram to predict the survival of individual with SCLC by incorporating significant clinical parameters. METHODS The patients with SCLC were enrolled from the First Affiliated Hospital of Guangzhou Medical University (GMUFAH) between 2009 and 2013. We identified and incorporated the independent prognostic factors to build a nomogram to predict the survival of SCLC patients. The predictive accuracy and discriminative ability of the nomogram were evaluated by concordance index (C-index) and calibration curve. We also compared the accuracy of the built model with the 7th AJCC TNM and VALSG staging system. The nomogram was further validated in an independent cohort of 80 patients with SCLC from Cancer Center of Guangzhou Medical University (GMUCC) between 2009 and 2013. RESULTS A total of 275 patients with SCLC were included in the primary cohort, and seven independent prognostic factors were identified including age, N stage, metastasis status, histology, platelets to lymphocyte ratio (PLR), neuron specific enolase (NSE) and CYFRA21-1 as independent prognostic factors after using Cox regression model. A nomogram incorporating these prognostic factors was subsequently built. The calibration curves for possibilities of 1-, 2-year overall survival (OS) revealed optimal agreement between nomogram prediction and actual observation. The C-index of this nomogram was higher than that of TNM and VALSG staging system in both primary and validation cohort (nomogram vs. TNM, primary cohort 0.68 vs. 0.65, P<0.01, validation cohort 0.66 vs. 0.62, P<0.05; nomogram vs. VALSG, primary cohort 0.68 vs. 0.66, P<0.01, validation cohort 0.66 vs. 0.64, P<0.05). CONCLUSIONS In this study, we established and validated a novel nomogram for the prediction of OS for the patients with SCLC. This model could provide more accurate individual prediction of survival probability of SCLC than the existing staging systems.

Abstract
Objective: To estimate the immune response of HepG2/dendritic cell (DC) fusion cells vaccines against HepG2 cells in vitro. Methods: Peripheral blood mononuclear cells (PBMCs) were isolated from healthy donors by Ficoll-Hypaque density-gradient centrifugation.Then DC were obtain from PBMCs by culturing in medium containing granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) for 5 days.DC and HepG2 fusion cells were induced by polythyleneglycol (PEG). The fusion cells were examined under fluorescence microscope by labeling DCs and HepG2 with green and red fluorescein, respectively, and then the fusion rates were analyzed by flow cytometry.The capacity of fusion cells to secrete interleukin (IL)-12 and stimulate the proliferation of T lymphocyte was assessed by ELISA and Flow cytometry, respectively.ELISPOT was used to assess the interferon gamma (IFN-γ) produced by cytotoxicity T lymphocyte (CTL), and the specific killing ability of fusion cells induce-CTL targeting HepG2 was estimated. Results: The fusion rate of HepG2/DC was 54.5%, and the fusion cells expressed a higher levels of DC mature marker CD80 and costimulatory molecules CD83, CD86 and MHC-Ⅰ, MHC-Ⅱ molecules HLA-ABC and HLA-DR than those in immature DCs (P<0.01). HepG2/DC showed a greater capacity to secrete high level of IL-12 (P<0.05) and activate proliferation of lymphocytes in vitro, as compared with DCs alone and DCs mix HepG2 (P<0.01). The HepG2/DC -activated CTL generated higher IFN-γ level and had a specific killing ability against HepG2 cells at the effecter/target ratio 30∶1 (31.4%±2.4%) and 100∶1 (57.6%±7.3%) (P<0.01). Conclusions: HepG2/DC fusion cells could efficiently stimulate T lymphocytes to generate specific CTL targeting HepG2 cells.It might be a promising strategy of immunotherapy for HCC.

Abstract
OBJECTIVES Little research has been done into the distance travelled by consumers to purchase alcohol, whether this is influenced by demographic characteristics or drinking levels of consumers, and the effect of price on purchase distance. This study aimed to explore distances drinkers were prepared to travel to purchase alcohol at on- and off-site outlets and how these decisions were affected by price discounting. STUDY DESIGN Online survey. METHODS The study, including 831 alcohol consumers aged 18 years and older living in Australian capital cities, was undertaken in 2012. The survey was used to gather data on the distances which participants anticipated that they usually travelled to purchase alcohol. The data provided insight into which factors influence where participants would choose to purchase alcohol and the possible effects of price discounts on purchase distance. RESULTS Most participants would choose to travel less than 10 km to purchase alcohol. Data indicated that price discounting might increase the purchase distance that most participants would be prepared to travel to purchase alcohol; this was more marked regarding off-site outlets and among high-risk drinking groups including young males and participants with risky drinking levels. CONCLUSIONS Price discounting affects hypothetical purchase distance choices, indicating the importance of price when implementing alcohol control policies. Purchase distance might be more affected by price discounting among consumers visiting off-site outlets, but less useful when exploring associations with on-site outlets.

Abstract
BACKGROUND Snap freezing and RNAlater stabilization are methods that were wildly used in biospecimen depositories to preserve cancer tissues. Both methods have its own limitations. An ideal method for preservation of diseased tissues should permit the broader uses of stored tissue samples, including not just for molecular diagnostic analysis, histopathological evaluation, but also for the recovery of functional live cells and tissues as well as the regeneration of patient-derived xenograft (PDX) models for the drug screening study. MATERIALS AND METHODS This study investigated molecular and pathological evaluation of cryopreserved colorectal cancer tissues, with an emphasis on effects of freezing method and cryoprotection. Global gene expression analysis with microarrays and histological examination of tissue samples were performed to compare tissue specimens after snap freezing, cryoprotectant permeation and subsequent cryopreservation. RESULTS Compared with the fresh tissue samples (immediately stabilized in RNAlater after collection), samples preserved by snap freezing exhibited the largest number of differentially-expressed genes. Some genes relate to neuron, drug addiction and drug binding, but the rest of differentially-expressed genes were functionally dispersive. Cryoprotectant permeation into tissue samples and subsequent cryopreservation via a rate-controlled freezing resulted in much less differentially expressed genes. Histological structures of tissue specimens were both well preserved by snap freezing and cryoproservation. CONCLUSION Snap freezing may not be as reliable as commonly considered. The pilot study demonstrates the feasibility of using cryopreservation to retain viable diseased tissues for multiple applications.

Abstract
Background The TNM staging system is far from perfect in predicting the survival of individual cancer patients because only the gross anatomy is considered. The survival rates of the patients who have the same TNM stage disease vary across a wide spectrum. This study aimed to develop a nomogram that incorporates other clinicopathologic factors for predicting the overall survival (OS) of non-metastatic nasopharyngeal carcinoma (NPC) patients after curative treatments. Methods We retrospectively collected the clinical data of 1520 NPC patients who were diagnosed histologically between November 2000 and September 2003. The clinical data of a separate cohort of 464 patients who received intensity-modulated radiation therapy (IMRT) between 2001 and 2010 were also retrieved to examine the extensibility of the model. Cox regression analysis was used to identify the prognostic factors for building the nomogram. The predictive accuracy and discriminative ability were measured using the concordance index (c-index). Results We identified and incorporated 12 independent clinical factors into the nomogram. The calibration curves showed that the prediction of OS was in good agreement with the actual observation in the internal validation set and IMRT cohort. The c-index of the nomogram was statistically higher than that of the 7th edition TNM staging system for predicting the survival in both the primary cohort (0.69 vs. 0.62) and the IMRT cohort (0.67 vs. 0.63). Conclusion We developed and validated a novel nomogram that outperformed the TNM staging system in predicting the OS of non-metastatic NPC patients who underwent curative therapy.

Abstract
BACKGROUND We aimed to summarize the diagnostic accuracy of white light bronchoscopy (WLB) and advanced techniques for airway pre-cancerous lesions and early cancer, such as autofluorescence bronchoscopy (AFB), AFB combined with WLB (AFB + WLB) and narrow-band imaging (NBI) bronchoscopy. METHODS We searched for eligible studies in seven electronic databases from their date of inception to Mar 20, 2015. In eligible studies, detected lesions should be confirmed by histopathology. We extracted and calculated the 2×2 data based on the pathological criteria of lung tumor, including high-grade lesions from moderate dysplasia (MOD) to invasive carcinoma (INV). Random-effect model was used to pool sensitivity, specificity, diagnostic odds ratio (DOR) and the area under the receiver-operating characteristic curve (AUC). RESULTS In 53 eligible studies (39 WLB, 39 AFB, 17 AFB + WLB, 6 NBI), diagnostic performance for high-grade lesions was analyzed based on twelve studies (10 WLB, 7 AFB, 7 AFB + WLB, 1 NBI), involving with totally 2,880 patients and 8,830 biopsy specimens. The sensitivity, specificity, DOR and AUC of WLB were 51% (95% CI, 34-68%), 86% (95% CI, 73-84%), 6 (95% CI, 3-13) and 77% (95% CI, 73-81%). Those of AFB and AFB + WLB were 93% (95% CI, 77-98%) and 86% (95% CI, 75-97%), 52% (95% CI, 37-67%) and 71% (95% CI, 56-87%), 15 (95% CI, 4-57) and 16 (95% CI, 6-41), and 76% (95% CI, 72-79%) and 82% (95% CI, 78-85%), respectively. NBI presented 100% sensitivity and 43% specificity. CONCLUSIONS With higher sensitivity, advanced bronchoscopy could be valuable to avoid missed diagnosis. Combining strategy of AFB and WLB may contribute preferable diagnosis rather than their alone use for high-grade lesions. Studies of NBI warrants further investigation for precancerous lesions.

Abstract
OBJECTIVE To study the polymorphisms of human platelet antigen (HPA) 1-16 and human leukocyte antigen (HLA)-A and -B loci among ethnic Han population from Shandong. METHODS A total of 588 samples from platelet donors were genotyped for the above loci with sequence-specific primer PCR and sequence-specific oligonucleotide probe PCR. RESULTS The frequencies of HPA-la, -1b, HPA-2a, -2b, HPA-3a, -3b, HPA-4a, -4b, HPA-5a, -5b, HPA-6a, -6b, HPA-15a, -15b were 0.9974, 0.0026, 0.9456, 0.0544, 0.5417, 0.4583, 0.9983, 0.0017, 0.9889, 0.0111, 0.9903, 0.0097, 0.5434 and 0.4583, respectively. The HPA-7-14 and HPA-16 showed no heterozygosity as the b allele was not detected in such loci. The most common genotypic combination for HPA was HPA-(1,4,7-14,16,17) aa-2aa-3ab-5aa -6aa-15ab (0.1820). HLA-A2 (0.3070) and HLA-B13 (0.1361) demonstrated the highest frequencies at their respective loci. CONCLUSION The HPA and HLA loci are highly polymorphic among ethnic Hans from Shandong. The distribution of HPA polymorphisms also shows a great ethnic and territorial difference. It is important to construct regional database for the genotypes of HPA and HLA loci for platelet donors.

Abstract
Background Adoptive immunotherapy (AI) has been applied in the treatment of non-small-cell lung cancer (NSCLC) patients, but the value of postoperative AI has been inconclusive largely as a result of the small number of patients included in each study. We performed a systematic review and meta-analysis to address this issue for patients with postoperative NSCLC. Methods Pubmed, Embase, Cochrane Library were searched for randomized controlled trials comparing adoptive immunotherapy with control therapies in postoperative NSCLC patients. The primary endpoint was overall survival. Hazard ratio (HR) was estimated and 95% confidence intervals (CI) were calculated using a fixed-effect model. Results Compared with control therapies, analyses of 4 randomized controlled trials (472 patients) showed a significant benefit of adoptive immunotherapy on survival (hazard ratio [HR] 0.61, 95% CI 0.45–0.84, p = 0.002), and a 39% reduction in the relative risk of death (no evidence of a difference between trials; p = 0.16, I² = 42%). In subgroup analyses by treatment cycles and treatment regimen, significant OS benefit was found in combination therapy of AI with chemotherapy, regardless of whether or not the treatment cycles were more than 10 cycles. Conclusion Adoptive immunotherapy has the potential to improve overall survival in postoperative NSCLC. The findings suggest this is a valid treatment option for these patients. Further randomized clinical trials are urgently needed.

Abstract
Purpose According to the lung cancer staging project, T1a (≤ 2 cm) non–small-cell lung cancer (NSCLC) should be additionally classified into ≤ 1 cm and > 1 to 2 cm groups. This study aimed to investigate the surgical procedure for NSCLC ≤ 1 cm and > 1 to 2 cm. Methods We identified 15,760 patients with T1aN0M0 NSCLC after surgery from the Surveillance, Epidemiology, and End Results database. Overall survival (OS) and lung cancer–specific survival (LCSS) were compared among patients after lobectomy, segmentectomy, or wedge resection. The proportional hazards model was applied to evaluate multiple prognostic factors. Results OS and LCSS favored lobectomy compared with segmentectomy or wedge resection in patients with NSCLC ≤ 1 cm and > 1 to 2 cm. Multivariable analysis showed that segmentectomy and wedge resection were independently associated with poorer OS and LCSS than lobectomy for NSCLC ≤ 1 cm and > 1 to 2 cm. With sublobar resection, lower OS and LCSS emerged for NSCLC > 1 to 2 cm after wedge resection, whereas similar survivals were observed for NSCLC ≤ 1 cm. Multivariable analyses showed that wedge resection is an independent risk factor of survival for NSCLC > 1 to 2 cm but not for NSCLC ≤ 1 cm. Conclusion Lobectomy showed better survival than sublobar resection for patients with NSCLC ≤ 1 cm and > 1 to 2 cm. For patients in whom lobectomy is unsuitable, segmentectomy should be recommended for NSCLC > 1 to 2 cm, whereas surgeons could rely on surgical skills and the patient profile to decide between segmentectomy and wedge resection for NSCLC ≤ 1 cm.

Abstract
OBJECTIVE Hypertension is a common disorder related to cardiovascular diseases and stroke. Identification of genetic variations related to hypertension may advance our knowledge of the molecular mechanism underlying blood pressure regulation. Here, we aimed to investigate the associations between ABCB1 gene polymorphisms and hypertension-related traits in 1154 Han Chinese subjects. PATIENTS AND METHODS A total of 13 SNPs in ABCB1 were genotyped. RESULTS Three SNPs were significantly associated with systolic blood pressure (SBP), including rs17327624 (p = 6.167 × 10-4, beta = 5.650), rs3789243 (p = 4.331 × 10-3, beta = 2.800), and rs4148734 (p = 3.514 × 10-3, beta = 3.692). Rs17327624 (p = 2.818 × 10-4, beta = 2.753) and rs3789243 (p = 6.345 × 10-3, beta = 1.497) were significantly associated with diastolic blood pressure (DBP) and rs17327624 was significantly associated with hypertension (p = 1.746 × 10-4, OR = 1.605). These three SNPs (rs17327624, rs3789243 and rs4148734) were also associated with hypertension in female subjects but no significant signal was detected in males. CONCLUSIONS Our results suggest that ABCB1 polymorphisms may contribute to the blood pressure variation in Han Chinese population and the effect may be specific in females. Further studies performed in other populations are needed to confirm our findings and elucidate the underlying molecular mechanism.
