Abstract
MicroRNAs (miRNAs) are a family of 19-24 nucleotide non-coding RNAs with posttranscriptional regulatory functions. The involvement of miRNAs in normal hematopoiesis implies that deregulated miRNAs might contribute to leukemogenesis. To date, although certain miRNAs have been established a clear oncogenic role in hematological malignancies, other individual miRNAs potentially involved in human leukemogenesis still remain elusive. In this report, we showed that miR-142-3p was upregulated in human T-leukemic cell lines and primary T-leukemic cells isolated from T-cell acute lymphoblastic leukemia (T-ALL) patients and its expressive levels were correlated with patients' prognosis. Such an oncogenic role of miR-142-3p could be explained by its targeting cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) and glucocorticoid receptor alpha (GRα). High levels of miR-142-3p resulted in low levels of cAMP and weak activity of PKA, thus relieving the inhibitory effect of PKA on T-leukemic cell proliferation. Meanwhile, miR-142-3p decreased GRα protein expression by directly targeting the 3'-untranslational region of GRα mRNA, leading to glucocorticoid resistance. Transfection of the miR-142-3p inhibitor effectively converted glucocorticoid resistance, because of the resultant increase of GRα expression and PKA activity. These findings suggest that miR-142-3p is critical in T-cell leukemogenesis and may serve as a potential therapeutic target in T-ALL patients.

Abstract
This study investigated the clinicopathological characteristics of mucinous gastric carcinoma (MGC) and assessed whether multidetector-row computed tomography (MDCT) could differentiate MGC from non-mucinous gastric carcinoma (NGC). Clinicopathological data from 542 patients with gastric carcinoma (23 MGC, 519 NGC), who underwent pre-operative MDCT examination and curative or palliative gastrectomy, were analysed. Only seven of the 23 patients with MGC were correctly diagnosed pre-operatively by endoscopic biopsy. The MGC patients had larger tumours, a higher frequency of lymph node metastases, were more likely to have tumours of tumour, node, metastasis stages III and IV, and were less likely to have a curative resection than NGC patients. In addition, five MGC patients had calcifications in the thickened gastric wall. In conclusion, MGC is rare and is detected mostly at an advanced stage. The diagnostic sensitivity of MGC by endoscopic biopsy was relatively low, whereas MDCT was helpful in distinguishing MGC from NGC.

Abstract
Tissue anoxia is the main mechanism of the shock reaction. Here, the effect of hyperoxygenated solution (HOS) on acute haemorrhagic shock was studied in rabbits. At 60 min after shock, rabbits were infused intravenously with hyperoxygenated solution at 10 (HOS1 group) or 20 ml/kg (HOS2 group) or with Ringer's solution at 10 ml/kg (RS group). Compared with values before shock, values after shock were lower for mean arterial pressure (MAP), more negative for base excess (BE) and higher for blood lactate (BL) and blood viscosity. After infusion, MAP declined more slowly in the HOS1 and HOS2 groups than in the RS group. At 30 and 60 min after infusion, arterial partial pressure of oxygen (PaO2) and oxygen saturation (SaO2) were higher and BE was less negative in the HOS1 and HOS2 groups than in the RS group, BL was lower in the HOS1 and HOS2 groups than in the RS group, and PaO2 and SaO2 were higher in the HOS2 group than in the HOS1 group. It was concluded that HOS infusion can rectify changes in vital signs more effectively than Ringer's solution after acute haemorrhagic shock in rabbits.

Abstract
BACKGROUND In recent years, many clinical studies have confirmed the value of laparoscopy-assisted gastrectomy (LAG) in gastric cancer surgery, especially in early stages. But the safety and oncologic adequacy of laparoscopy-assisted D2 radical gastrectomy for advanced gastric cancer are still in debate. We conducted a prospective randomized trial to compare open versus laparoscopy-assisted D2 radical gastrectomy in advanced gastric cancer. METHODS For this study, 123 patients who had been diagnosed endoscopically with gastric cancer were randomly assigned to either LAG (n = 61) or open gastrectomy (OG) (n = 62) which ran from March 2008 to December 2009. Clinical characteristics, operative findings, postoperative recovery, morbidity, pathological report and survival rate were compared. D2 lymph node dissection was performed in 49 patients in the LAG group and 47 patients in the OG group with advanced gastric cancer. We adopt sub-group analysis in this paper. RESULTS The clinical characteristics of patients in the LAG and OG groups who were in the advanced stage, included age, sex, BMI and concurrent illness, and their ECOG scores were well matched. Operative findings, postoperative recovery, morbidity, pathological findings including tumor location, depth of invasion, TNM stage, histological grade and surgical extension in the two groups were also similar. Compared to the OG group, the mean operating time was significantly longer for the LAG group (267.88 ± 54.284 min in the LAG group vs. 182.02 ± 41.016 min in the OG group, p = 6.383 × 10(-13)); the mean number of days when body temperature exceeded 37°C was significantly shorter in the LAG group (p = 6.34 × 10(-8)). There were no postoperative deaths in both the groups. The postoperative morbidity rate was 12.24% in the LAG group and 19.15% in the OG group with no significant difference (p = 0.357). However, pulmonary infection was observed more frequently in the OG group (p = 0.038). After a mean follow-up of 22.1354 months (from 4 to 36 months), 14 and 15 patients died of gastric cancer in the LAG and OG groups, respectively. Two and one patient died of nongastric cancer in the LAG and OG groups, respectively. The overall survival rates were 67.1% and 53.8% in the LAG and OG groups, respectively. The estimated mean survival time was 29.387 months in the LAG group and 28.978 months in the OG group. There was no statistically significant difference in the overall survival rate for patients in both groups - LAG and OG (log-rank test, p = 0.911, Tarone Ware test, p = 0.994, and Breslow test, p = 0. 961). CONCLUSION LAG with D2 lymph node dissection is a safe and feasible procedure with adequate lymphadenectomy, good curability and survival rate for the treatment of advanced gastric cancer.

Abstract
We report a comprehensive x-ray scattering study of the low-temperature orthorhombic (LTO)-high-temperature tetragonal (HTT) structural phase transition in 1% iron-doped La(2-x)Sr(x)CuO(4) (x = 0.2). The superlattice (032) peak intensity and the width are investigated in detail for a wide temperature range. We found that the structural phase transition is not sharp and the tilt ordering of the CuO(6) octahedra persists above the transition temperature T(S) (≈77 K). Even at room temperature, the superlattice peak is still observable. The structural phase transition is identified as an order-disorder type phase transition. We found that the tilt ordering in our iron-doped material is always short-ranged, and in the HTT phase the correlation between the tilts along the b axis is better preserved than that along the a axis. Moreover, we identify the role of the Fe as the nucleation centers of the LTO domains in the structural phase transition.

Abstract
Anorexia nervosa (AN) is a mental illness with high mortality that most commonly afflicts adolescent female individuals. Clinical symptoms include chronic food refusal, weight loss and body image distortions. We carried out a genome-wide association study on 1033 AN cases and 3733 pediatric control subjects, all of whom were of European ancestry and were genotyped on the Illumina HumanHap610 platform (Illumina, San Diego, CA, USA). We confirmed that common single-nucleotide polymorphisms (SNPs) within OPRD1 (rs533123, P=0.0015) confer risk for AN, and obtained suggestive evidence that common SNPs near HTR1D (rs7532266, P=0.04) confer risk for restricting-type AN specifically. However, no SNPs reached genome-wide significance in our data, whereas top association signals were detected near ZNF804B, CSRP2BP, NTNG1, AKAP6 and CDH9. In parallel, we performed genome-wide analysis on copy number variations (CNVs) using the signal intensity data from the SNP arrays. We did not find evidence that AN cases have more CNVs than control subjects, nor do they have over-representation of rare or large CNVs. However, we identified several regions with rare CNVs that were only observed in AN cases, including a recurrent 13q12 deletion (1.5 Mb) disrupting SCAS in two cases, and CNVs disrupting the CNTN6/CNTN4 region in several AN cases. In conclusion, our study suggests that both common SNPs and rare CNVs may confer genetic risk to AN. These results point to intriguing genes that await further validation in independent cohorts for confirmatory roles in AN.
