Abstract
An instrument used for measuring multiple scintillators' light output and energy resolution was developed. The instrument consisted of a light sensor array which was composed of 64 discrete SiPMs (Silicon Photomultipliers), a corresponding individual channel readout electronics system, and a data processing algorithm. A Teflon grid and a large interval between adjacent SiPMs were employed to eliminate the optical cross talk among scintillators. The scintillators' light output was obtained by comparing with a reference sample with known light output. Given the SiPM temperature dependency and the difference among each SiPM, a temperature offset correction algorithm and a non-uniformity correction algorithm were added to the instrument. A positioning algorithm, based on nine points, was designed to evaluate the performance of a scintillator array. Tests were performed to evaluate the instrument's performance. The uniformity of 64 channels for light output measurement was better than 98%, the stability was better than 98% when temperature varied from 15 °C to 40 °C, and the nonlinearity under 511 keV was better than 2%. This instrument was capable of selecting scintillators and evaluating the packaging technology of scintillator arrays with high efficiency and accuracy.

Abstract
OBJECTIVE The aim of this study was to investigate the expression of PTPN12 in human breast cancer and its role in predicting the efficacy of neoadjuvant chemotherapy (NACT) for breast cancer. PATIENTS AND METHODS The PTPN12 expression levels were assessed by immunohistochemical staining in 114 breast cancer patients. The correlation of PTPN12 with clinicopathological features was also analyzed. Multivariate logistic regression was used to explore the effect of PTPN12 expression in predicting clinical response. RESULTS We observed a significant association of PTPN12 expression with cTNM classification. The overall pathological complete response (pCR) rate was 23.2 % in high PTPN12 expression group, whereas it was 5.2% in low PTPN12 expression group. The multivariate regression analyses further indicated that clinical response correlated with PTPN12 expression level and cycles of NACT, and CEX regimen was associated with the overall pathological complete response. In addition, Spearman rank correlation analyses suggested that higher PTPN12 expression indicated better clinical response in breast cancer patients. Furthermore, PTPN12 expression statistically related with pathological response in TNBC and Luminal B subtypes, as assessed by Pearson Chi-square test or Fisher's exact test. CONCLUSIONS Our study informed that cTNM classification is an independent risk factor for PTPN12 expression and PTPN12 is an independent predictor to clinical remission.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies in Western countries. Over the last 20 years, and the last decade in particular, the clinical outcome for patients with metastatic CRC (mCRC) has improved greatly due not only to an increase in the number of patients being referred for and undergoing surgical resection of their localised metastatic disease but also to a more strategic approach to the delivery of systemic therapy and an expansion in the use of ablative techniques. This reflects the increase in the number of patients that are being managed within a multidisciplinary team environment and specialist cancer centres, and the emergence over the same time period not only of improved imaging techniques but also prognostic and predictive molecular markers. Treatment decisions for patients with mCRC must be evidence-based. Thus, these ESMO consensus guidelines have been developed based on the current available evidence to provide a series of evidence-based recommendations to assist in the treatment and management of patients with mCRC in this rapidly evolving treatment setting.

Abstract
BACKGROUND The clinical value of the prognostic nutritional index (PNI) in gastric cancer (GC) remains controversial. Therefore, we performed the meta-analysis to determine the prognostic and clinicopathological values of PNI in patients with GC. METHODS A literature search was performed in the PubMed, Embase, and Web of Science databases. Hazard ratios (HRs) and odds ratios (ORs) were extracted to estimate the association of PNI with survival and clinicopathological characteristics, respectively. RESULTS Ten studies involving 3396 patients with GC were analyzed. The pooled results indicated that a low PNI was a significant predictor of poor overall survival (OS) (HR = 1.89, 95% confidence interval [CI] = 1.67-2.13, P < 0.01) and postoperative complications (OR = 1.74, 95% CI = 1.41-2.16, P < 0.01). In the subgroup analysis, a low PNI was significantly associated with poor OS in patients with GC at stage I, II and III, but not at stage IV (HR = 1.14, 95% CI = 0.84-1.55, P = 0.40). Moreover, a low PNI was significantly associated with more advanced tumor features, such as older age, deeper depth of tumor, positive lymph node metastasis, more advanced TNM stages, and positive vessel and lymphatic invasion. CONCLUSION PNI was a predictive indicator of survival and postoperative complications, and was associated with clinicopathological features in GC patients. However, a low PNI was not significantly associated with poor OS in patients with GC at stage IV.

Abstract
Lung cancer, especially adenocarcinoma, is one of the leading causes of death in the world. Carcinoembryonic antigen (CEA), a superb non-small-cell lung cancer marker candidate, showed a beneficial effect in cancer therapy with oncolytic adenovirus in recent studies. Cancer-targeting dual gene-virotherapy delivers two therapeutic genes, linked by a connexon, in the replication-deficient vector instead of one gene so that they can work in common. In this study, we constructed a tumor-specific oncolytic adenovirus, CD55-TRAIL-IETD-MnSOD. The virus has the fusion protein complementary DNAs for tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and for manganese superoxide dismutase (MnSOD) complementary DNA linked through a 4-amino acid caspase-8 cleavage site (IETD), and uses a CEA promoter to control virus E1A express. This is the first work to use a CEA promoter-regulated oncolytic adenovirus carrying two therapeutic genes for cancer research. Its targeting and anticancer capacity was evaluated by in vitro and in vivo experiments. The results indicated that CD55-TRAIL-IETD-MnSOD caused more cell apoptosis than CD55-TRAIL or CD55-MnSOD alone, or their combination in vitro, with low cytotoxicity of normal cells. In the A549 tumor xenograft model in nude mice, data showed that CD55-TRAIL-IETD-MnSOD could effectively suppress tumor growth than single gene groups, with no histological damage in liver, spleen or kidney tissues. Thus, the CEA-regulated dual-gene oncolytic virus CD55-TRAIL-IETD-MnSOD may be a novel potential therapy for lung cancer.

Abstract
OBJECTIVES Dietary recommendations to reduce blood pressure (BP) have been widely disseminated and residents who live on islands have unique dietary characteristics. Here, we identified associations between dietary intake and BP levels among island residents in China. DESIGN Cross-sectional study. SETTING The Changhai islands, which is an important island county in China. PARTICIPANTS A total of 876 residents, 18-88 years old, of Changhai county. MEASUREMENTS Dietary intake and BP measurements were assessed using standardized questionnaires and protocols, respectively. Dietary intake was compared across BP categories and linear regression analyses were performed between dietary intake and systolic blood pressure (SBP) and diastolic blood pressure (DBP). RESULTS Participants previously diagnosed with hypertension consumed less salt than those with undiagnosed high BP (p < 0.01). After exclusion of participants previously diagnosed with hypertension, salt and meat consumption were positively and linearly associated with both SBP (p < 0.01 and < 0.001, respectively) and DBP (p = 0.03 and < 0.01, respectively), whereas consumption of marine products was inversely associated with SBP (p = 0.047). Mixed edible oil and edible oil consumption were associated with SBP (p < 0.01) and DBP (p = 0.021), respectively. In the multiple linear regression model, meat intake was positively associated with both SBP and DBP (β = 0.139, p < 0.001; β = 0.066, p = 0.047, respectively), whereas consumption of marine products was inversely associated with SBP (β = -0.102, p <0.001), while mixed edible oil was associated with SBP (β = 0.062, p = 0.03). CONCLUSION Adherence to nutritional recommendations can be improved among hypertensive patients, even those aware of their conditions. In the general island population, eating habits regarding salt, meat, edible oil consumption, and use of mixed edible oil increased the risk of hypertension onset, whereas marine products were found to decrease this risk.

Abstract
Half-metallic Co-based full-Heusler alloys with perpendicular magnetic anisotropy (PMA), such as Co2FeAl in contact with MgO, are receiving increased attention recently due to its full spin polarization for high density memory applications. However, the PMA induced by MgO interface can only be realized for very thin magnetic layers (usually below 1.3 nm), which would have strong adverse effects on the material properties of spin polarization, Gilbert damping parameter, and magnetic stability. In order to solve this issue, we fabricated oxidized Co50Fe25Al25 (CFAO) films with proper thicknesses without employing the MgO layer. The samples show controllable PMA by tuning the oxygen pressure (PO2) and CFAO thickness (tCFAO), large perpendicular anisotropy field of ~8.0 kOe can be achieved at PO2 = 12% for the sample of tCFAO = 2.1 nm or at PO2 = 7% for tCFAO = 2.8 nm. The loss of PMA at thick tCFAO or high PO2 results mainly from the formation of large amount of CoFe oxides, which are superparamagnetic at room temperature but become hard magnetic at low temperatures. The magnetic CFAO films, with strong PMA in a relatively wide thickness range and small intrinsic damping parameter below 0.028, would find great applications in developing advanced spintronic devices.

Abstract
BACKGROUND/OBJECTIVES Folic acid supplementation has been suggested to reduce the risk of preeclampsia. However, results from few epidemiologic studies have been inconclusive. We investigated the hypothesis that folic acid supplementation and dietary folate intake before conception and during pregnancy reduce the risk of preeclampsia. SUBJECTS/METHODS A birth cohort study was conducted in 2010-2012 at the Gansu Provincial Maternity & Child Care Hospital in Lanzhou, China. A total of 10,041 pregnant women without chronic hypertension or gestational hypertension were enrolled. RESULTS Compared with nonusers, folic acid supplement users had a reduced risk of preeclampsia (OR=0.61, 95% CI: 0.43-0.87). A significant dose-response of duration of use was observed among women who used folic acid supplemention during pregnancy only (P-trend=0.007). The reduced risk associated with folic acid supplement was similar for mild or severe preeclampsia and for early- or late-onset preeclampsia, although the statistical significant associations were only observed for mild (OR=0.50, 95% CI: 0.30-0.81) and late-onset (OR=0.60, 95% CI: 0.42-0.86) preeclampsia. The reduced risk associated with dietary folate intake during pregnancy was only seen for severe preeclampsia (OR=0.52, 95% CI: 0.31-0.87, for the highest quartile of dietary folate intake compared with the lowest). CONCLUSIONS Our study results suggest that folic acid supplementation and higher dietary folate intake during pregnancy reduce the risk of preeclampsia. Future studies are needed to confirm the associations.
