Abstract
This study compared the efficiency and safety of radiotherapy plus erlotinib with concurrent chemoradiotherapy (CCRT) based on paclitaxel plus cisplatin in elderly esophageal cancer patients. The eligible patients were retrospectively enrolled at Wenzhou Medical University cancer center from January 2005 to December 2011. Propensity score matching generated a matched cohort (1:1) composed from radiotherapy plus erlotinib and CCRT groups. The efficiency and safety were compared between two groups. Multivariable analysis was used to identify significant prognostic factors. Thirty-four patients treated with radiotherapy plus erlotinib were matched with patients who received CCRT. Radiotherapy plus erlotinib group showed better treatment compliance compared with the CCRT group (91.2% vs. 67.6%, hazard ratio [HR] 0.202, 95% confidence interval [CI] 0.051-0.809; P = .016). No significant overall response rate differences were found between the two groups (88.2% vs. 79.4%, HR 0.514, 95% CI 0.135-1.952; P = .323). The 5-year overall survival (OS) rate was 23.5% vs. 19.2% for patients treated with CCRT or radiotherapy plus erlotinib (HR 1.008, 95% CI 0.574-1.768; P = .979). The 5-year progression-free survival (PFS) rate was 16.8% versus 17.1% for patients treated with CCRT or radiotherapy plus erlotinib, respectively (HR 0.978, 95% CI 0.576-1.662; P = .934). The rate of severe hematologic toxicities in the CCRT group was significantly higher than that in the radiotherapy plus erlotinib group (HR 4.306, 95% CI 1.066-17.389; P = .031). Late toxicities were similar between radiotherapy plus erlotinib group and the CCRT group. Multivariate analysis showed that T stage (HR 1.730, 95% CI 1.062-2.816; P = .028), M stage (HR 2.859, 95% CI 1.407-5.811; P = .004), and complete response (HR 2.154, 95% CI 1.190-3.901; P = .011) were independent prognostic factors associated with OS. In conclusion, the present study suggested radiotherapy plus erlotinib should be a preferable modality compared with CCRT, with similar survival outcomes but better treatment compliance and less toxicities.

Abstract
Objective: To analyze the quantitative expression and prognostic significance of tumor neo-vessels, macrophages and fibroblasts in tumor microenvironment of hepatocellular carcinoma (HCC). Methods: The clinic-pathological features and tissue samples for 101 HCC cases were collected. Immunohistochemistry was used to stain the tumor neo-vessels, macrophages and fibroblasts on tumor tissue. The distribution results and quantitative data of above key components were acquired by inverted microscopy equipped with CRi Nuance multispectral analysis system. The number of tumor neo-vessels and macrophages on HCC tissue were counted and the thickness of cancer stroma based on the expression of fibroblasts was measured. The clinic-pathological characteristics and overall survival were analyzed. Results: The median disease free survival (DFS) of 101 HCC cases was 5 month. The quantitative analysis of tumor neo-vessels, macrophages and fibroblasts showed that the expression range was 51-429 with median 218, 110-555 with median 259, 35.61-555.35 with median 246.98, respectively. To take the median as cutoff, all the cases could be classified into high and low expression group. The survival analysis demonstrated that the high density group of macrophages (P=0.022) and fibroblasts (P<0.001) has shorter DFS than low density group, with statistical significance. The high tumor neo-vessels group has shorter DFS with median 5 month than low density group with median 7 month. However, there was no statistical significance between these two group (P=0.197). Combined with above the three stromal components, all the cases could be classified into low, middle and high group. The survival analysis demonstrated that the high density group of stromal components has shorter DFS than the other two groups with median 3 month (P=0.001). Multivariate analysis by Cox regression indicated that cirrhosis, metastasis status, macrophages and fibroblasts density were the independent prognostic factors. Conclusion: The key elements in tumor microenvironment including tumor neo-vessels, macrophages and fibroblasts were heterogenic in HCC tissues and played significant roles in HCC invasion and metastasis.

Abstract
The monitoring of malignant transformation of hepatocytes or early diagnosis of primary hepatocellular carcinoma (PHC) remains a challenge in the medical world. Routine examinations including serum alpha-fetoprotein level and ultrasound examination have a limited value in the diagnosis of small hepatocellular carcinoma; however, the effective treatment of PHC depends on its early diagnosis. In recent years, molecular markers including important signaling molecules in PHC-related pathways, carcinoembryonic proteins, and non-coding RNA help with the monitoring of malignant transformation of hepatocytes or early diagnosis of liver cancer. This article reviews the valuable molecular markers in the monitoring of malignant transformation of hepatocytes or early diagnosis of liver cancer.

Abstract
Objective: To investigate the dynamic expression of hepatic carnitine palmitoyltransferase-II (CPT-II) in the mitochondrial inner membrane during hepatocyte malignant transformation induced by lipid accumulation. Methods: Male Sprague-Dawley rats were divided randomly into control, fatty liver, and induced cancer groups, which were fed with normal, high-fat (HF), and HF containing 2-fluorenylacetamide (0.05%, 2-FAA) diets, respectively, for 14 weeks. One rat from each group was sacrificed every two weeks and the blood and liver samples were collected. Liver morphological changes were evaluated with hematoxylin and eosin staining, and the liver tissue samples were divided into control, fatty liver, degeneration, precancerous, and cancerous groups accordingly. Hepatic lipids were dyed by the oil red O method. The CPT-II expression was measured by immunohistochemistry and compared with the specific CPT-II concentration (ng/mg liver protein, ng/mg P) among different groups. Serum levels of circulating total cholesterol (Tch), triglyceride (TG), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were quantitatively analyzed. Results: Massive lipid accumulation hepatocytes was seen in rats on HF and HF containing 2-FAA diets. The lipid levels in the control group were significantly lower than those in the fatty liver (t = -11.556, P < 0.001), degeneration (t = -4.847, P = 0.04), precancerous (t = -13.652, P = 0.005), and cancerous groups (t = -10.896, P = 0.008). The serum TG and Tch levels in the degeneration, precancerous, and cancerous groups were 2-3 times higher than those in the control group (P < 0.05). After 2-FAA treatment, the morphological changes of rat hepatocytes showed the progression from degeneration and precancerosis to cancerosis, with hepatocyte injury. The serum AST and ALT levels in the degeneration, precancerous, and cancerous groups were significantly higher (4-8 times) than those in the control group (P < 0.05). The specific concentration of liver CPT-II expression was significantly reduced during hepatocyte malignant transformation, as confirmed by immunohistochemistry, with the CPT-II levels significantly lower in the cancerous group than in any of other groups (P < 0.05). Conclusion: Low hepatic CPT-II expression might lead to abnormal lipid accumulation in hepatocytes, which should promote the malignant transformation of hepatocytes.

Abstract
Abstract
Purpose:
To investigate the usefulness of radiomics signature based on computed tomographic (CT) spectral imaging, during the late arterial phase (AP) and portal venous phase (PVP), in preoperative predicting the lymph node (LN) metastasis in breast cancer (BC).
patients and methods:
This retrospective study was institutional review board approved, and written informed consent was obtained from all patients. We examined 60 female patients (LN metastasis positivity was 50%) with CT spectral imaging during the AP and the PVP and data was gathered from 2014 to 2016. Excised lymph nodes were located and labeled during surgery according to location on preoperative CT images and were evaluated histopathologically. For each patient, two 3D Hounsfeld Unit (HU) gradient maps which revealed the HU change of each voxel were built by quadratic fitting the spectral HU curves during the two phases respectively. Then the radiomics features were then extracted from the regions of BC and a suspicious LN judged manually in these maps. The potential association of the four groups of radiomics features with LN status was assessed by using a Mann-Whitney U test. The area under curves (AUC) of the receiver operating characteristic curves (ROC) were compared with data obtained from the conventional CT image.
results:
The 3D HU gradient map showed a great power of distinguishing among different components and was considered as a more effective tool for revealing the intratumour heterogeneity than the conventional CT image since the slope of spectral HU curves were significantly higher in malignant tumor. More than 500 radiomics features extracted from the regions of LN during the AP and the PVP exhibited significant differences (P <0.05). Moreover, the numbers of this kind of features extracted from the regions of BC were more than 200. The highest AUC of single feature was 0.70, which was higher than those from the conventional CT image.
Conclusion:
Quantitative radiomics features based on 3D HU gradient maps have the potential to be exploited as an effective biomarker for preoperative prediction of lymph node metastasis in breast cancer.

Abstract
Cerebral edema causes intracranial hypertension (ICH) which leads to severe outcome of patients in the clinical setting. Effective anti-edema therapy may significantly decrease the mortality in a variety of neurological conditions. At present drug treatment is a cornerstone in the management of cerebral edema. Osmotherapy has been the mainstay of pharmacologic therapy. Mannitol and hypertonic saline (HS) are the most commonly used osmotic agents. The relative safety and efficacy of HS and mannitol in the treatment of cerebral edema and reduction of enhanced ICP have been demonstrated in the past decades. Apart from its osmotic force, HS exerts anti-edema effects partly through inhibition of Na(+)-K(+)-2Cl(-) Cotransporter-1 (NKCC1) and aquaporin 4 (AQP4) expression in astrocytes. Melatonin may also reduce brain edema and exert neuroprotective effect on several central nervous system diseases through inhibition of inflammatory response. The inhibitors of Na/H exchanger, NKCC and AQP4 may attenuate brain edema formation through inhibition of excessive transportation of ion and water from blood into the cerebral tissue. In this review we survey some of the most recent findings in the drug treatment of brain edema focusing on the use of osmotherapy, melatonin and inhibitors of ion cotransporters and water channels. A better understanding of the molecular mechanism of these agents would help to improve in the clinical management of patients with brain edema.

Abstract
Objective: To explore Wnt3a expression in HCC tissues and serum, and to discuss its clinical diagnostic and prognostic value. Methods: The Wnt3a expressions were detected in a total of 186 patients (HCC, liver cirrhosis and chronic Hepatitis) and 40 controls by Elisa, comparing with AFP to evaluate its clinical diagnosis value. Wnt3a expressions in 80 HCC and surrounding tissues were analyzed by IHC, to explore its prognostic value. Results: Wnt3a with brown staining was mainly distributed in cytosol and of hepatocyte membrane. The higher expression (3-6 scores) was 71.3% in HCC, 13.8% in surrounding tissues, associated with poorly-differentiated grade, liver cirrhosis, HBV infection, higher TNM stage (P<0.05) and 5-year survival rate (P<0.001), identified as independent predictive factors for poor HCC outcome and closely related with lower five-year survival rate. Serum average Wnt3a levels were significantly higher (P<0.001) in the HCC group than those in any other groups of benign liver diseases, with about 4.0, 9.2 and 26.7 times higher than that in the liver cirrhosis, chronic hepatitis and normal control group. Wnt3a expression in HCC were closely related to AFP concentration, liver cirrhosis HBV infection, poor differentiation, TNM stagingand extra- hepatic metastasis (P<0.05). The sensitivity, specificity, accuracy, positive predictive value and negative predictive values were 92.5, 94.3, 93.2, 96.1 and 89.3% at 800 ng/L as cutoff value for Wnt3a. Combining Wnt3a and AFP test, the total sensitivity could rise to 96.3%. The area under ROC curve in Wnt3a (0.994)was higher than in AFP (0.710). Conclusions: Wnt3a as a critical signal molecule in the Wnt pathway is a new specific marker for HCC diagnosis and prognosis.

Abstract
Magnetic refrigeration based on the magnetocaloric effect (MCE) is an environment-friendly, high-efficiency technology. It has been believed that a large MCE can be realized in the materials with a first-order magnetic transition (FOMT). Here, we found that TlFe3Te3 is a ferromagnetic metal with a first-order magnetic transition occurring at Curie temperature TC = 220 K. The maximum values of magnetic entropy change (Δ) along the crystallographic c-axis, estimated from the magnetization data, reach to 5.9 J kg-1K-1 and 7.0 J kg-1 K-1 for the magnetic field changes, ΔH = 0-1 T and 0-2 T, respectively, which is significantly larger than that of MCE materials with a second-order magnetic transition (SOMT). Besides the large ΔSM, the low-level both thermal and field hysteresis make TlFe3Te3 compound an attractive candidate for magnetic refrigeration. Our findings should inspire the exploration of high performance new MCE materials.
