Background and purpose:Early evaluating the therapeutic efficacy of transcatheter arterial chemoembolization (TACE) in patients with hepatic cancer is still a diffcult clinical problem. The purpose of this study was to evaluate the ability of the apparent diffusion coeffcient (ADC) to help predict early disease progression after TACE.Methods:Institutional review board approval was obtained, and all patients signed informed consent. Magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) (b=50, 500, 1 000 mm2/s) were performed before and 1 month after initiating TACE for 23 patients with hepatic cancer (14 were male, 9 were female; mean age: 53.3 years;range: 21-85 years). Contrast-enhanced MRI was performed 3 months after initiating TACE. Patients were classiifed as either progressing or non-progressing according to RECIST 1.1. The preoperative ADC values of tumor and the ADC values of tumor 1 month after TACE were analyzed by pairedt-test in both progressing and non-progressing group. Unpairedt-test was used to compare ADC parameters between progressing and non-progressing group. In all the 23 hepatic cancer patients, receiver operating characteristic (ROC) curve analysis was performed to determine a threshold ADC ratio (ADC%) to differentiate progressing from non-progressing patients.Results:Thirteen progressing and 9 non-progressing patients were evaluated. Increase in ADCs of tumor was observed in non-progressing patients at 1 month after TACE compared with preoperative ADCs. There was a signiifcant difference between the 2 groups (P=0.01). In progressing group, preoperative ADCs of tumor were similar to those at 1 month after TACE (P=0.221). There was no significant difference in preoperative ADCs of tumor and ADC% between the progressing and non-progressing groups. In patients with hepatic cancer, 1 month ADC ratio in non-progressing patients were signiifcantly higher than those of progressing patients (P=0.029). Using ROC to evaluate the ability of ADC% could predict early disease pro-gression after TACE. Using -6.455% as the threshold, the area under the ROC curve was 0.867 (95%CI: 0.643-1.000). The sensitivity was 100%, and the speciifcity was 66.7%.Conclusion:One month after TACE, the increases in ADCs of tumor were observed only in the non-progressing group; and the ADC ratio seems to be a promising tool for helping predict the early disease progression after TACE in patients with hepatic cancer.

OBJECTIVETo evaluate the correlation of liver hardness testing

RESULTSobtained by FibroTouch and FibroScan and the liver pathological stage.

METHODSSeventy-five patients with chronic hepatitis B who presented to our clinic between January 2011 and April 2013 were examined with FibroTouch and FibroScan to evaluate the degree of liver fibrosis. Forty-six of those patients also underwent liver biopsy examination.

THE RESULTSfrom technology-based testing and histopathological evaluation of the biopsy were compared by statistical analysis to determine the consistency of FibroTouch and FibroScan in regard to histological stage.

RESULTSAnalysis by paired t-test showed that the

RESULTSfrom FibroTouch and FibroScan were not significantly different (t = -0.17, P =0.8616), and the correlation coefficient from Pearson's correlation analysis was 0.9949 (P less than 0.05), suggesting that the two technologies'

RESULTSare correlated. Based on the histopathology

RESULTSfor liver fibrosis stage, the FibroTouch diagnosis of liver fibrosis more than or equal to S 1 had a receiver operating characteristic (ROC) area under the curve (AUC) of 0.889, diagnosis of liver fibrosis more than or equal to S2 had a ROC AUC of 0.941, diagnosis of liver fibrosis more than or equal to S3 had a ROC AUC of 0.908, and diagnosis of liver fibrosis more than or equal to S4 had a ROC AUC of 0.911.

CONCLUSIONCompared to FibroScan, FibroTouch has a better ability for detecting liver fibrosis and a better consistency with liver pathological stage determined by histopathological analysis.

Objective: To investigate the expression of programmed death ligand 1 (PD-L1) in liver cancer tissues and its clinical significance. Methods: The expression levels of PD-L1 in 110 liver cancer tissues, including 95 cases of hepatocellular carcinoma and 15 cases of cholangiocarcinoma were detected by using immunohistochemical staining method, and the relationship between PD-L1 expression and the clinicopathological characteristics of patients with hepatocellular carcinoma was analyzed. Results: Immunohistochemistry results showed that the positive rate of PD-L1 in liver cancer tissues was 69.1% (76/110), and the positive rate of membrane and cytoplasm was 46.4% (51/110) and 22.7% (25/110), respectively. The positive rate of PD-L1 expression in hepatocellular carcinoma was higher than that in cholangiocarcinoma [78.9% (75/95) vs. 6.7% (1/15)], and the difference was statistically significant (χ ² = 31.693, P < 0.01). The positive expression of PD-L1 was closely associated with the depth of invasion and TNM stage of hepatocellular carcinoma (both χ² = 4.629, both P = 0.031), but there was no relationship with the patients'age, gender and pathological grade (all P > 0.05). Further analysis showed that protein expression localization of PD-L1 was closely related to the pathological grade in hepatocellular carcinoma (P = 0.013). Conclusion The positive expression of PD-L1 in hepatocellular carcinoma is closely associated with depth of invasion and TNM stage, which provides a theoretical basis for the immunotherapy of liver cancer targeting PD-L1.

As a homeobox transcription factor,MEOX1 can regulate the target genes by binding the specific DNA sequence.MEOX1 not only plays essential roles in cell proliferation,migration and differentiation,but also participates in the formation of skeleton,muscle and blood vessel during embryonic development.Recent studies demonstrate that MEOX1 is over-expressed in breast cancer,lung cancer,ovarian cancer and prostate cancer tissues,which is closely associated with lymph node metastasis and poor prognosis in patients with cancer.Furthermore,MEOX1 can regulate the proliferation and migration of cancer cells,which suggests that it plays an important role in the occurrence and development of tumors.

Objective To observe the differential expression of high mobility group box - 1 protein (HMGB1) in renal tissues of heat stroke mice models, and to explore its role in the pathogenesis of heat stroke associated acute kidney injury(HS-associated AKI). Methods According to random number table, 20 healthy male C57BL/6J mice were randomly divided into 2 groups, including normal control (n=10) and heat stroke group (n=10). The mice in heat stroke group were given with a 2-hour-exposure in biological simulation chamber (temperature 41℃, humidity 70％). Heat stroke was defined as anal temperature lasting more than 40 degrees Celsius. A 18F - deoxyglucose nuclide labeled vivo imaging was conducted with micro - positron emission tomography(PET)/computer tomography (CT). Serum creatinine was examined with blood example. In order to evaluate the pathological changes, HE stain was conducted with kidney tissue, and mitochondrial morphological changes in kidney tissue were observed by transmission electron microscopy. The expressions of HMGB1 and apoptosis inducing factor mitochondria associated 2 (Aifm2) were examined by immunohistochemical method, and the levels of HMGB1 and RAGE were examined by Western blotting. The cell apoptosis of renal tissue was detected by terminal deoxynucleotidyl transferase -mediated dUTP - biotin nick end labeling assay (TUNEL). The metabolomics of kidney tissue in mice were detected by liquid chromatography - mass spectrometry (LC - MS), and the pathway enrichment analysis was carried out by KEEG database. Results (1) The body temperature of the mice in heat shock group was significantly higher than that in normal control group 45 min after model establishment (P＜0.05). The level of serum creatinine in heat shock group was significantly higher than that in normal control group (P＜0.05), and the levels of 18F - deoxyglucose increased in skeletal muscle and visceral tissue of the mice in heat - shock group. (2) HE staining showed hemorrhage in collecting duct and tubular endothelial cell swelling, and mitochondrial swelling and deformation were observed by transmission electron microscopy in kidney tissue of the heat shock group. (3) Immunohistochemical method showed that the levels of Aifm2 and HMGB1 in heat shock group were higher (P＜0.05). (4) Western blotting showed that the levels of HMGB1 and RAGE in heat shock group were higher than those in normal control group (P＜0.05). (5) TUNEL showed that the number of cells with positive stain in kidney tissue of the heat shock group was higher than that in normal control group (P＜0.05). (6) Between normal control group and heat shock group, 136 differential metabolites were detected in kidney tissues. After analysis by KEGG database, pathway abnormalities such as unsaturated fatty acid metabolism disorder may be associated with HS - associated AKI, and many differential metabolites such as adrenic acid may be important regulatory points in the pathogenesis. Conclusion Acute kidney injury is a common complication of heat shock. It may be related to the dysfunction of renal mitochondria and activation of apoptotic pathway caused by systemic hypercatabolism, which may be related to the disorder of unsaturated fatty acid metabolism and activation of HMGB1. Some differential metabolites may be of high value in HS- associated AKI studies.
