Abstract
Objective: To investigates the role of piwi-interacting RNAs (piRNA) in the occurrence and development of hepatocellular carcinoma. Methods: Second-generation small RNA sequencing was performed on cancer and paracancerous tissues, metastatic and non-metastatic liver cancer tissues of patients with liver cancer, and the sequencing data were filtered out for the common RNA sequences to be repeated. The piRNA predictor was used to forecast the possible new piRNA merged with the downloaded known piRNA to screen out distinction. A miRanda algorithm was used to predict the corresponding target genes and functional enrichment analysis. piRNA was selected for experimental functional (migration) analysis. An independent t-test was used to compare means between the two groups. Results: 66 772 piRNAs (known 149) were obtained by sequencing. 241 piRNAs were found in cancer and paracancerous tissues, and 1 634 piRNAs were found in metastatic and non-metastatic tumors. Analysis of the GO and KEGG pathways of the target genes of differential piRNAs revealed that they were mainly involved in cell adhesion. An experimental functional analysis was performed on the selected Pirna (PIR1/97), which showed that it promoted the migration of hepatoma cells (LM3: t = 8.829, P < 0.05; PLC: t = 7.318, P < 0.05). Conclusion: The expression levels of piRNA in hepatocellular carcinoma patients with cancer and paracancerous tissues, metastasis and non-metastatic liver cancer tissues are different and it could be entailed in the metastasis process of hepatocellular carcinoma. Hence, experimental functional analysis is required for research and experimental confirmation.

Abstract
The aim of this study is to evaluate the reliability, validity, and acceptability of the Chinese version of the EORTC QLQ-OES18 in patients with esophageal cancer. The questionnaire was translated according to the guideline of the EORTC. One hundred and forty-nine patients with esophageal cancer from Tianjin Medical University Cancer Institute and Hospital completed the Karnofsky performance scale (KPS) and the simplified Chinese EORTC QLQ-C30/OES18 scales during July 2013 to January 2014. The results were statistically analyzed by Cronbach's α coefficient, Spearman correlation test with multiple strengthen analysis, and Wilcoxon Rank Sum test. The internal consistency (Cronbach's α coefficient) of all four scales (dysphagia, eating, reflux, and pain) was 0.689-0.822, which were satisfactory or near satisfactory. The absolute values of correlation of each scale between EORTC QLQ-OES18 and EORTC QLQ-C30 were 0.002-0.750 while there was no significant difference between groups divided by KPS scores. We confirmed the Chinese version of EORTC QLQ-OES18 appears to be a reliable, valid, and acceptable instrument for measuring the health-related quality of life of patients with esophageal cancer in mainland China.

Abstract
Objective: To further understand the interaction protein spectrum of heterogeneous ribonucleoprotein AB (hnRNP AB), and to investigate their clinical significance in hepatocellular carcinoma (HCC). Methods: We carried out mass spectrometry to reveal the specific peptides of KRAB-associated protein 1 (Kap1) and hnRNPAB, and verified their interaction by immunocoprecipitation and western blotting. Expression of hnRNPAB/Kap1 proteins were detected by immunohistochemical staining in the tissue microarrays. Categorical data were analyzed by the chi square test or Fisher exact test; enumeration data between groups were compared using Student t-test or Wilcocon signed rank test; the cumulative recurrence and survival rates were evaluated using the Kaplan-Meier method and the differences were assessed using the log-rank test. Results: We identified Kap1 as a molecular partner for hnRNPAB in HCCLM3 cells and HepG2 cells as well. We found that the 5-year survival rate of the Kap1high patients was significantly lower than the survival rate of those of the Kap1low group (36% vs 59% , HR = 1.67, P < 0.001). Similarly, Kap1high HCC patients had the poorest prognosis at 5-years, with higher cumulative recurrence rate than Kap1low patients (72% vs 54%, HR = 1.66, P = 0.001). Univariate and Multivariate analyses revealed that hnRNPAB /Kap1 alone (HR = 1.35 /1.28, P = 0.001) or in combination with Kap1 (HR =1.24 /1.27, P < 0.05) were independent prognostic indicators for overall survival and time to recurrence. Conclusion: In HCC cells, hnRNPAB and Kap1 form protein complexes. The expression levels of hnRNPAB alone or in combination with Kap1 in HCC patients are important because they provide not only a predictor for HCC prognosis but also a therapeutic target for future studies.

Abstract
Lipodystrophy is a common complication in HIV-infected patients taking highly active antiretroviral therapy. Its early diagnosis is crucial for timely modification of antiretroviral therapy. We hypothesize that mitochondrial DNA in plasma may be a potential marker of LD in HIV-infected individuals. In this study, we compared plasma mitochondrial DNA levels in HIV-infected individuals and non-HIV-infected individuals to investigate its potential diagnostic value. Total plasma DNA was extracted from 67 HIV-infected patients at baseline and 12, 24 and 30 months after initiating antiretroviral therapy. Real-time quantitative PCR was used to determine the mitochondrial DNA levels in plasma. Lipodystrophy was defined by the physician-assessed presence of lipoatrophy or lipohypertrophy in one or more body regions. The mitochondrial DNA levels in plasma were significantly higher at baseline in HIV-infected individuals than in non-HIV-infected individuals (p<0.05). At month 30, 33 out of 67 patients (49.2%) showed at least one sign of lipodystrophy. The mean plasma mitochondrial DNA levels in lipodystrophy patients were significantly higher compared to those without lipodystrophy at month 24 (p<0.001). The receiver operating curve analysis demonstrated that using plasma mitochondrial DNA level (with cut-off value <5.09 log10 copies/ml) as a molecular marker allowed identification of patients with lipodystrophy with a sensitivity of 64.2% and a specificity of 73.0%. Our data suggest that mitochondrial DNA levels may help to guide therapy selection with regards to HIV lipodystrophy risk.

Abstract
UNLABELLED Treatment with zoledronic acid in osteoporotic patients with spinal fusion shortens the duration of time to fusion, improves the fusion rate, prevents the subsequent adjacent vertebral compression fractures, improves the clinical outcomes, and prevents immobilization-induced bone loss in the hip. INTRODUCTION The objective of the study was to explore the effects of zoledronic acid on the healing process in osteoporotic patients following spinal fusion in a randomized, placebo-controlled, and triple-blinded study. METHODS Seventy-nine osteoporotic patients with single-level degenerative spondylolisthesis were randomly assigned to receive either zoledronic acid infusion (zoledronic acid group) or saline infusion (controls) after spinal fusion. Functional radiography and CT scans were used to evaluate fusion status. Bone formation was graded into three categories: Grade A (bridging bone bonding with adjacent vertebral bodies), Grade B (bridging bone bonding with either superior or inferior vertebral body), or Grade C (incomplete bony bridging). A solid fusion was defined as less than 5° of angular motion with Grade A or B bone formation. Adjacent vertebral compression fractures (VCF) were assessed on MRI at 12 months after surgery. Serum level of carboxy terminal cross-linked telopeptide of type I collagen (β-CTX) and amino-terminal propeptide of type I procollagen (PINP) was measured. Bone mineral density (BMD) was measured by DXA. Oswestry Disability Index (ODI) was used to assess the clinical outcomes. RESULTS Grade A or B bridging bone was more frequently observed in zoledronic acid group at 3, 6, and 9 months post-operation compared to the control group (p < 0.05). At 12 -months post-operation, bridging bone and solid fusion were not significantly different between groups. No patients in zoledronic acid group showed aVCF, whereas six patients (17 %) in the control group did (p < 0.05). Both β-CTX and PINP were suppressed in zoledronic acid group. BMD at the femoral neck decreased rapidly and did not return to the preoperative level in the controls at 3 (-1.4 %), 6 (-2.5 %), and 12 (-0.8 %) months after surgery. Zoledronic acid prevented this immobilization-induced bone loss and increased BMD. ODI showed the improved clinical outcomes compared with controls at 9 and 12 months post-surgery. CONCLUSION Treatment with zoledronic acid in osteoporotic patients with spinal fusion shortens the time to fusion, improves the fusion rate, prevents subsequent aVCFs, and improves clinical outcomes.
