Moreover, the levels of most hub genes were related to immune cell infiltration in HCC microenvironments. Finally, we identified three upregulated genes (KPNA2, TARBP1, and RNASEH2A) that could comprehensively and accurately provide diagnostic and prognostic value for HCC patients.Nutrient oversupply and mitochondrial dysfunction play central roles in nonalcoholic fatty liver disease (NAFLD). selleck The mitochondria are the major sites of β-oxidation, a catabolic process by which fatty acids are broken down. The mitochondrial quality control (MQC) system includes mitochondrial fission, fusion, mitophagy and mitochondrial redox regulation, and is essential for the maintenance of the functionality and structural integrity of the mitochondria. Excessive and uncontrolled production of reactive oxygen species (ROS) in the mitochondria damages mitochondrial components, including membranes, proteins and mitochondrial DNA (mtDNA), and triggers the mitochondrial pathway of apoptosis. The functionality of some damaged mitochondria can be restored by fusion with normally functioning mitochondria, but when severely damaged, mitochondria are segregated from the remaining functional mitochondrial network through fission and are eventually degraded via mitochondrial autophagy, also called as mitophagy. In this review, we describe the functions and mechanisms of mitochondrial fission, fusion, oxidative stress and mitophagy in the development and progression of NAFLD.It is crucial to grasp the characteristics of tumour immune microenvironment to improve effects of immunotherapy. In this study, the immune and stromal scores of 371 cases were calculated for quantitative analysis of immune and stromal cell infiltration in the tumour microenvironment of hepatocellular carcinoma (HCC). The weighted gene co-expression network analysis and protein-protein interaction network were analysed to identify immune microenvironment-related genes. The results showed that patients with high immune scores had a higher 4-year recurrence-free rate. TP53, CTNNB1, and AXIN1 mutations significantly varied with immune scores. In immune score-related modules analysis, Kyoto encyclopaedia of genes and genomes pathways and gene ontology terms were closely related to immune processes, tumorigenesis, and metastasis. Twelve new immune microenvironment-related genes were identified and had significantly positive correlations with seven immune checkpoint genes. In prognostic analysis, eleven immune microenvironment-related genes exhibited high expression, nine of which were validated in the GSE62232 dataset and were significantly associated with a good prognosis. Our findings suggest that calculating immune score and stromal score could help to determine tumour purity and immune cell infiltration in the tumour microenvironment. Nine immune microenvironment-related genes identified in this study had potential as prognostic markers for HCC.INTRODUCTION AND AIM Ectopic ACTH secretion (EAS) is mostly secondary to thoracic/abdominal neuroendocrine tumours (NETs), or small cell-lung carcinoma (SCLC). We studied the diagnostic accuracy of computed tomography (CT) with 68Ga-Dota derivatives (68Ga-SSTR) positron emission tomography (PET) in localizing ACTH-secreting tumor in patients with EAS. MATERIALS AND METHODS 68Ga-SSTR-PET/CT was performed and compared with the nearest enhanced CT in 18 cases (16 primary and 2 recurrent neoplasms). Unspecific, indeterminate and false positive uptakes were assessed using conventional imaging, follow-up or histology. RESULTS We diagnosed 13 thoracic (9 primary and 2 recurrent bronchial carcinoids, 2 SCLCs) and 1 abdominal (pancreatic NET) tumors. 8 ACTH-secreting tumors were promptly identified at EAS diagnosis ('overt', 4 pulmonary carcinoids with 2 recurrences, and 2 SCLC); 6 EAS have been discovered during the subsequent follow-up ('covert', 5 bronchial carcinoids and 1 pancreatic NET). At the time of EAS diagnosis, imaging was able to correctly detect the ACTH-secreting tumour in 8/18 cases (6 new diagnosis and 2 recurrences). During the follow-up, 6 out of initially 10 'occult' cases became 'covert'. At last available follow-up, CT and 68Ga-SSTR-PET/CT were able to diagnose respectively 11/18 and 12/18 ACTH-secreting tumours (respectively 11/14 and 12/14 considering only overt and covert cases). 4 cases have never been localized by conventional or nuclear imaging ('occult' EAS), despite an average follow up of 5 years. CONCLUSIONS The 68Ga-SSTR-PET/CT is useful in localizing EAS, especially to enhance positive prediction of the suggestive CT lesions and to detect occult neoplasms.BACKGROUND Hypogonadism is prevalent during opioid treatment, but the effect of testosterone replacement treatment (TRT) on body composition, pain perception, and adrenal function is unclear. PURPOSE To measure changes in body composition, pain perception, quality of life and adrenal function after TRT or placebo in opioid treated men with chronic non-malignant pain. METHODS Double-blind, placebo-controlled study in 41 men (>18 years) with total testosterone less then 12 nmol/L were randomized to 24 weeks TRT (Testosterone undecanoate injection 3 times/6 months, n=20) or placebo (placebo-injections, n=21). OUTCOMES Body composition (lean body mass and fat mass assessed by DXA), clinical pain intensity (numerical rating scale), and experimental pain perception (quantitative sensory assessment), quality of life (SF36), and adrenocorticotrophic hormone (ACTH) test. Data were presented as median (quartiles). Mann Whitney tests were performed on delta values (24-0 weeks) between TRT and placebo. RESULTS The median age was 55 years (46; 59) and total testosterone before intervention was 6.8 (5.0; 9.3) nmol/L. TRT was associated with change of testosterone levels 12.3 (7.0; 19.9) nmol/L (p less then 0.001 vs. placebo), increased lean body mass 3.6 (2.3; 5.0) kg vs. 0.1 kg (-2.1; 1.5) during TRT vs. placebo and decreased total fat mass -1.2 (-3.1; 0.7) kg vs. 1.2 kg (-0.9; 2.5) kg, both p less then 0.003. Changed pain perception, SF36, and ACTH stimulated cortisol levels were non-significantly changed during TRT compared with placebo. CONCLUSIONS Six months TRT improved body composition in men with opioid induced hypogonadism without significant changes in outcomes of pain perception, quality of life or adrenal function.
