Additional file 1: Table S1. Charateristics of NSCLC patients.

Tumors have exceptionally high demands for energy and anabolism because of their rapid growth. The de novo serine synthesis pathway initiated by phosphoglycerate dehydrogenase (PHGDH) has been recognized as a hallmark of metabolic adaption in carcinogenesis. The oncogenic role and prognostic value of PHGDH have been investigated in multiple cancer types, including breast cancer, melanoma, cervical cancer, and colon cancer. Due to the importance of PHGDH in cancer, we attempted to determine the clinical significance of PHGDH in 319 patients with non–small cell lung cancer (NSCLC). We evaluated the mRNA and protein expression levels of PHGDH gene, using quantitative reverse transcriptase polymerase chain reaction and tissue array–based immunohistochemistry, respectively. Significantly increased PHGDH expression in mRNA and protein levels was identified in tumor tissues versus matched adjacent nontumor tissues. More interestingly, immunohistochemical expression of PHGDH was significantly associated with lymph node metastasis (P = .021) and TNM stage (P = .016). Kaplan-Meier survival analysis indicated that NSCLC patients with low levels of PHGDH outperformed patients with high levels of PHGDH regarding 5-year overall survival. Significantly longer survival in the former suggested the prognostic implication of PHGDH in NSCLC. Multivariate survival analysis using Cox regression model demonstrated that high PHGDH levels and advanced TNM stage (III + IV) were independent predictors of prognosis in NSCLC. Moreover, bioinformatics analysis confirmed the increase in PHGDH transcripts (data from The Cancer Genome Atlas) and its prognostic value (Kaplan-Meier plotter) in NSCLC. In conclusion, this study suggested the clinical implication of PHGDH in NSCLC. PHGDH may be a promising therapeutic target in NSCLC.

Objectives Serum Ghrelin was measured in patients of acute coronary syndrome (ACS). Investigate whether serum levels of Ghrelin are associated with the Gensini score on patients with ACS. Methods 75 cases of patients with ACS were divided into 28 cases of unstable angina (UA), 11 cases of non-ST elevation myocardial infarction (NSTEMI) and 36 cases of ST elevation myocardial infarction (STEMI), 13 cases of normal angiography as the control group. The level of Ghrelin in serum was detected with enzyme linked immunosorbent assay way, Gensini Scores was used to assess the severity of coronary artery disease. The correlation between the level of Ghrelin and Gensini score was analysed. Results The level of Ghrelin in patients with STEMI was lower than the patients in group of NSTEMI. The level of the Ghrelin in patients with NSTEMI was lower than the patients in group of UA. The level of the Ghrelin in patients with UA was lower than the patients in the control group. There was significant statistically differences among the four groups (p Conclusions The level of Apelin might involve in the pathogenesis of acute coronary syndrome, moreover, the activity of apelin was negatively correlated with the severity of the coronary artery lesions.
