[Q]: It remains controversial whether the cure of H. pylori infection improves NUD symptoms.', 'To conduct a double-blind placebo-controlled single centre study with concealed allocation to investigate this question.', 'Ninety NUD patients with H. pylori infection were randomly assigned to either the treatment group (50 patients) or placebo group (40 patients). The treatment group received omeprazole, amoxycillin, clarithromycin and the placebo group received omeprazole and placebos for 7 days. Symptoms were assessed every week for up to 12 weeks after completion of medication by a symptom questionnaire. Alteration of histological parameters for gastritis was also evaluated.', 'The infection was cured in 41 out of 48 patients in the treatment group and none in the placebo group. There was no significant difference in the mean symptom scores at any assessment point up to 12 weeks between the treatment and placebo groups. Regarding histological parameters, activity and inflammation, not atrophy or intestinal metaplasia, were significantly improved in the treatment group.

[Q]: Ischemia/reperfusion (I/R) injury, which is commonly seen in the field of renal surgery or transplantation, is a major cause of acute renal failure (ARF). The ischemic ARF in diabetic rats is much more severe than that in the normal rats exposed to as same ischemic time. Ischemic post-conditioning (IPO) is a phenomenon by which intermittent interruptions of blood flow in the early phase of reperfusion can protect organs from I/R injury. To determine whether the renal protection effect of IPO mediates by toll-like receptor 4 (TLR4) signaling pathway in diabetic rats.', 'Streptozotocin-induced diabetic rats were randomly divided into three groups: sham operation group, I/R group, and IPO group. Except sham operation group, rats were subjected to 30\u2009min of renal ischemia, both with and without treatment with IPO, then reperfusion 24\u2009h. Light microscope and transmission electronic microscope were used to observe structural changes of renal tubule. RT-PCR was used to measure TLR4 and tumor necrosis factor-alpha (TNF-α) mRNA expression level, renal TLR4 and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) protein expression was detected by Western blot.', 'The results demonstrated that IPO markedly decreased renal ischemic injury caused by I/R and inhibited the proinflammatory expression levels of TLR4, TNF-α, and NF-κB, all of which up-regulated by I/R in diabetic rats.

[Q]: Genetic and molecular signatures have been incorporated into cancer prognosis prediction and treatment decisions with good success over the past decade. Clinically, these signatures are usually used in early-stage cancers to evaluate whether they require adjuvant therapy following surgical resection. A molecular signature that is prognostic across more clinical contexts would be a useful addition to current signatures.', 'We defined a signature for the ubiquitous tissue factor, E2F4, based on its shared target genes in multiple tissues. These target genes were identified by chromatin immunoprecipitation sequencing (ChIP-seq) experiments using a probabilistic method. We then computationally calculated the regulatory activity score (RAS) of E2F4 in cancer tissues, and examined how E2F4 RAS correlates with patient survival.', "Genes in our E2F4 signature were 21-fold more likely to be correlated with breast cancer patient survival time compared to randomly selected genes. Using eight independent breast cancer datasets containing over 1,900 unique samples, we stratified patients into low and high E2F4 RAS groups. E2F4 activity stratification was highly predictive of patient outcome, and our results remained robust even when controlling for many factors including patient age, tumor size, grade, estrogen receptor (ER) status, lymph node (LN) status, whether the patient received adjuvant therapy, and the patient's other prognostic indices such as Adjuvant! and the Nottingham Prognostic Index scores. Furthermore, the fractions of samples with positive E2F4 RAS vary in different intrinsic breast cancer subtypes, consistent with the different survival profiles of these subtypes.
