Abstract
This clinical study assessed the etiological factors implicated in acute kidney injury (AKI). AKI has a complicated etiology with many serious complications. Understanding the interactions among these factors will help physicians treat patients with AKI. This retrospective study analyzed the etiological factors and assessed the incidence and outcome of 123 patients with AKI and multiple organ dysfunction syndrome. The general conditions, original disease, number of organ dysfunctions, type of organ dysfunction, complications, score, time, dose of renal replacement therapy, and outcomes were recorded. The etiologies of the manifested diseases were complicated. The number of injured organs was directly associated with prognosis. Cardiovascular dysfunction and cataphora were independently associated with a risk of mortality (P < 0.05; odds ratios: 12.44 and 2.16, respectively). Meanwhile, cardiovascular dysfunction and choloplania were independently associated with a risk of irreparable renal function (P < 0.05; odds ratios: 23.64 and 11.59, respectively). In summary, the etiologies of the manifested diseases are complex. In addition, cardiovascular dysfunction is significantly associated with prognosis including survival and the recovery rate of renal function.

Abstract
In this review, we first analyzed the current status of cholinergic anti-inflammatory pathway and then put forward a novel regulatory machinery-pulmonary parasympathetic inflammatory reflex, which is composed by lung vagal sensors at afferent arm, α7 nAChR (α7 nicotinic acetylcholine receptors)-expressing cells at efferent arm and the brain information integrating center. This modulatory circuit might loop the lungs, immune and nervous systems and play a very important role in regulating lung infection, inflammation and immunity through the neural innervations and signals when the lungs encounter pathogenic challenges.

Abstract
Exergames have started to find their way into field-based settings, such as schools, communities and homes, as a possible solution to curbing physical inactivity and childhood obesity. However, a clear view of the effects of field-based exergaming on children's obesity-related outcomes is lacking. Hence, a systematic review on this topic is warranted. This review synthesizes the impact of field-based exergames on children's physical and psychosocial outcomes. A total of 34 articles conducted in field-based settings were identified from 104 peer-reviewed publications that investigated the effects of exergames. Upon screening, these articles met the inclusion criteria and a high inter-rater agreement for inclusion was reached between the authors. The effects of field-based exergames on children's habitual physical activity (PA) and obesity-related outcomes (e.g. weight loss, body composition) remain unclear due to design problems, measurement issues and other methodology concerns. In addition, exergame is appealing to children, although strategies are warranted to sustain their interests. In summary, exergames are desirable as a promising addition to promote PA and health. Professionals may integrate exergames at field settings to promote a physically active lifestyle among children with the goal of curbing childhood obesity.

Abstract
CBL-interacting protein kinases (CIPKs) mediate many plant responses to abiotic stress. However, their functions are poorly understood in halophytes. In this study, we isolated a CIPK gene, NtCIPK2, from the halophyte Nitraria tangutorum. By sequence alignment and the construction of a phylogenetic tree, we found that NtCIPK2 is similar to CIPK2 proteins from other plants, and contains conserved domains and motifs. The promoter of NtCIPK2 harbors many cis-acting elements that might be recognized and bound by transcription factors that are related to hormones and stress responses. NtCIPK2 was ubiquitously and robustly expressed in all tested organs, and was induced by salinity, drought, heat, and cold stress. The overexpression of NtCIPK2 in Escherichia coli caused better growth against high salinity, alkalinity, and osmotic conditions, dehydration, and extreme temperatures (i.e., heat and cold) compared to the control. Thus, NtCIPK2 is a candidate gene that might improve the stress tolerance of crops and herbs through genetic manipulation.

Abstract
Electroacupuncture has been demonstrated to be effective at alleviating pain and postoperative side-effects. Our aim was to investigate whether transcutaneous electric acupoint stimulation, a low-skill alternative to needle-based electroacupuncture, could improve the quality of recovery after ambulatory surgery. Seventy-two women scheduled for cosmetic breast surgery were randomly allocated to transcutaneous electric acupoint stimulation or sham groups. Patients in the transcutaneous electric acupoint stimulation group received 30 min of electrical stimulation at three acupoints located on the hand and forearm before the induction of general anaesthesia. We found significant mean (SD) differences between the transcutaneous electric acupoint stimulation and sham groups in the mean (SD) length of recovery room stay (35.6 (12.9) min vs 48.3 (16.3) min, p = 0.01), time to removal of the laryngeal mask airway (10.2 (2.5) min vs 17.8 (4.4) min, p = 0.01), and time to reorientation of the patient (14.6 (3.2) min vs 26.5 (5.0) min, p = 0.01). Further, postoperative pain scores and the incidence of side-effects were all lower in the transcutaneous electric acupoint stimulation group. In conclusion, transcutaneous electric acupoint stimulation can significantly improve the quality of recovery and decrease the incidence of anaesthesia-related side-effects for patients undergoing ambulatory surgery.

Abstract
AIM To investigate the immunomodulatory effects of β-(1,3/1,6)-d-glucan on atherosclerosis as well as on the molecular mechanisms of its transition. METHODS AND RESULTS Human monocytic leukemia (THP-1) cells were differentiated into the macrophage phenotype by incubation with oxLDL in the absence or presence of β-glucan. β-glucan attenuated CD86 and CD80 expression and simultaneously reduced secretion of the inflammatory cytokines IL-2, IL-8, IL-12, TNF-α and IFN-γ. Western blot analysis showed that oxLDL treatment induced phosphorylation of p38 MAPK and ERK1/2 in PMA-differentiated THP-1 cells. However, β-glucan inhibited p38 MAPK activation. In experiments with monocytes derived from healthy donors, β-glucan inhibited IL-8, IL-12 and TNF-α production. The anti-inflammatory effects of β-glucan were also observed in atherosclerotic plaque cells. CONCLUSIONS β-glucan inhibited oxLDL-induced pro-inflammatory effects in macrophages via regulation of p38 MAPK phosphorylation. This novel finding may provide insight for new therapeutic strategies.

Abstract
Measuring treatment outcome is important for successful tuberculosis (TB) control programmes. The purpose of this study was to examine the outcomes of various types of TB cases registered in Pakistan over a 2-year period and compare those outcomes among the different provinces and regions of the country. A retrospective, cohort study was conducted in which TB treatment outcome reports were reviewed. Of the 349 694 pulmonary TB cases registered in Pakistan during 2006 and 2007, 309154 (88.4%) were treated successfully. Treatment success was significantly higher in new smear-positive cases and lower in retreatment cases. Among the provinces and regions, treatment success was significantly higher in 4 out of 8 provinces. Treatment success needs to be improved, particularly in retreatment cases. The national TB control programme should review the provincial and regional programmes and learn lessons from well-performing programmes. Patient factors that may affect the treatment outcome should be also studied.

Abstract
The aim of this study was to evaluate the efficacy and safety of telbivudine 600 mg/day compared with lamivudine 100 mg/day for 48 weeks of treatment in patients with hepatitis B-related cirrhosis. Data were reviewed retrospectively from 165 hepatitis B-related cirrhotic patients (55 compensated patients and 110 decompensated) who received antiviral therapy with telbivudine or lamivudine. Serum alanine aminotransferase (ALT) and hepatitis B virus (HBV) DNA levels, hepatitis B e antigen (HBeAg) loss and seroconversion, histological improvement and various adverse events (AEs) were evaluated. Baseline characteristics were comparable. ALT levels declined but showed no significant difference in treatment with telbivudine or lamivudine (P > 0.05). Reduction in serum HBV DNA levels was evident by week 4 in compensated HBV-related cirrhosis patients (telbivudine, 2.34 log10 copies/mL; lamivudine, 2.07 log10 copies/mL; P = 0.02) and persisted by week 8. Patients administrated with telbivudine had slightly greater HBeAg loss and seroconversion than patients with lamivudine, but the difference was not statistically significant (P > 0.05). Accumulative HBeAg loss was seen at week 48 (25.0% vs 25.0% and 13.3% vs 10.0% for telbivudine vs lamivudine in compensated and decompensated cirrhotic groups, respectively), as well as HBeAg seroconversion (15.0% vs 8.3% and 8.9% vs 6.7%). Mean Knodell Histologic Activity Index scores decreased in both compensated and decompensated cirrhotic patients (3.92 vs 3.64, 3.85 vs 3.73, for telbivudine vs lamivudine). Telbivudine and lamivudine were both well tolerated with minor AEs. The results of this study support telbivudine as an effective therapy for patients with both compensated and decompensated HBV-related cirrhosis.

Abstract
The aim of this study was to investigate the efficacy of sequential use of telbivudine in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B patients with partial responses to pegylated interferon. Patients with partial responses to 48 weeks of pegylated interferon treatment were divided into two groups. In group A, patients stopped pegylated interferon directly without sequential treatment. In group B, patients received sequential treatment with telbivudine 600 mg/day. HBeAg, HBeAb, hepatitis B virus (HBV) DNA, alanine aminotransferase (ALT) and creatine kinase levels were determined at baseline and at weeks 12, 24, 36 and 48. Responses and safety were assessed after 48 weeks of telbivudine treatment. Thirty-six patients were recruited. Eighteen of these patients stopped pegylated interferon without sequential treatment (group A). After 48 weeks of follow-up, five patients (28%) had undergone HBeAg seroconversion, nine patients (50%) had undetectable levels of HBV DNA, and 11 patients (61%) achieved normal alanine aminotransferase (ALT) levels. The other 18 patients received sequential telbivudine treatment (group B). After 48 weeks of treatment, 11 patients (61%) had undergone HBeAg seroconversion, and all patients had undetectable levels of HBV DNA and normal ALT levels. All patients tolerated sequential telbivudine treatment, and only slightly elevated creatine kinase levels were observed. Switching to telbivudine therapy was efficient and safe in HBeAg-positive chronic hepatitis B patients with partial responses to 48 weeks of pegylated interferon. Sequential treatment with telbivudine resulted in an HBeAg seroconversion rate of 61% and an HBV DNA loss rate of 100% after 48 weeks. This promising strategy warrants further investigation.

Abstract
OBJECTIVE Obesity is associated with an increase in various pro-inflammatory and anti-inflammatory cytokines, but the interplay of these cytokines is incompletely understood. We conducted experiments to test a broader hypothesis that a dynamic interplay of pro-inflammatory and anti-inflammatory cytokines controls lipid storage in adipocytes. DESIGN Three experiments were designed to test the overall hypothesis that proinflammatory cytokine (for example, tumor necrosis factor-α (TNF-α) inhibits anti-inflammatory cytokine (for example, adiponectin) activity in an attempt to limit excess lipid accumulation in adipocytes. RESULTS Experiment one showed that in pro-inflammatory animal models (ap2-P65, ob/ob and high-fat diet-induced obese mice), the increase in TNF-α expression was associated with a decrease in adiponectin expression. Experiment two showed that in 3T3-L1 adipocytes, TNF-α significantly reduced lipid accumulation and glucose uptake induced by adiponectin, and increased lipolysis. Experiment three showed that in 3T3-L1 adipocytes, TNF-α reduced mRNA and protein expression of adiponectin. Adiponectin gene transcription and mRNA stability were both reduced by TNF-α. The expression of peroxisome proliferator-activated receptor gamma, an activator of adiponectin gene promoter, was reduced by TNF-α. The inhibitory activity of TNF-α was blocked by the chemical inhibitors of NF-κB and super suppressor IκBα. CONCLUSIONS TNF-α opposes the action of adiponectin in the regulation of lipid metabolism, and inhibits adiponectin expression at transcriptional and post-transcriptional levels. The results suggest that pro-inflammatory cytokine inhibit anti-inflammatory cytokine in adipocytes to reduce lipid storage. This suggests a potential role of anti-inflammatory cytokines in the control of adipose tissue expansion.

Abstract
Nasal-type extranodal NK/T cell lymphoma (NK/TCL) is a rare malignancy that usually presents as a destructive midline lesion in the nasal region. The incidence of nasal-type extranodal NK/TCL has been reported to be much higher in Asia and South America than in North America and Europe. Its diagnosis mainly relies on histopathological and immunohistochemical examinations. Most patients demonstrate rapid disease progression and short survival. This report concerns a 37-year-old male with nasal-type extranodal NK/TCL showing severe facial disfigurement who was initially misdiagnosed as having Aspergillus infection. The report emphasizes the clinical manifestations and the importance of pathological diagnosis.

Abstract
UNLABELLED People with spinal cord injury (SCI) lose bone and muscle integrity after their injury. Early doses of stress, applied through electrically induced muscle contractions, preserved bone density at high-risk sites. Appropriately prescribed stress early after the injury may be an important consideration to prevent bone loss after SCI. INTRODUCTION Skeletal muscle force can deliver high compressive loads to bones of people with spinal cord injury (SCI). The effective osteogenic dose of load for the distal femur, a chief site of fracture, is unknown. The purpose of this study is to compare three doses of bone compressive loads at the distal femur in individuals with complete SCI who receive a novel stand training intervention. METHODS Seven participants performed unilateral quadriceps stimulation in supported stance [150% body weight (BW) compressive load-"High Dose" while opposite leg received 40% BW-"Low Dose"]. Five participants stood passively without applying quadriceps electrical stimulation to either leg (40% BW load-"Low Dose"). Fifteen participants performed no standing (0% BW load-"Untrained") and 14 individuals without SCI provided normative data. Participants underwent bone mineral density (BMD) assessment between one and six times over a 3-year training protocol. RESULTS BMD for the High Dose group significantly exceeded BMD for both the Low Dose and the Untrained groups (p < 0.05). No significant difference existed between the Low Dose and Untrained groups (p > 0.05), indicating that BMD for participants performing passive stance did not differ from individuals who performed no standing. High-resolution CT imaging of one High Dose participant revealed 86% higher BMD and 67% higher trabecular width in the High Dose limb. CONCLUSION Over 3 years of training, 150% BW compressive load in upright stance significantly attenuated BMD decline when compared to passive standing or to no standing. High-resolution CT indicated that trabecular architecture was preserved by the 150% BW dose of load.

Abstract
BACKGROUND To perform a follow-up of 25 Chinese children with gene-confirmed PLA2G6-associated neurodegeneration (PLAN). METHODS We recruited patients with infantile neuroaxonal dystrophy (INAD) according to the criteria proposed by Nardocci et al. Follow-up was conducted from 7 months to 8 years after the first visit. The PLA2G6 gene was sequenced, and copy number variation (CNV) was detected in patients with only one mutant allele and in mutation-negative patients. Patients with late-onset PLAN until 2012 were reviewed. RESULTS All patients with INAD exhibited rapid decline in motor and mental function, consistent with previous reports from other populations. Epileptic seizures occurred in 16.7%. One teenager with late-onset PLAN was diagnosed and followed up. The age of disease onset in published late-onset PLAN ranged between 18 months and 37 years. Initial presentations included gait instability (79.0%), mood/behavior changes (10.5%), dysarthria (5.26%) and cognitive deterioration (5.3%). Compared with INAD, cerebellar atrophy (42.1%) was less frequent in the late-onset cases, with cerebral atrophy more common (71.4%). Brain iron accumulation was seen in 52.6%. PLA2G6 mutations were identified by DNA sequencing in 92.3% of clinically diagnosed INAD cases and in the late-onset case. Twenty-seven different mutations were found, of which 13 were novel. No CNVs were detected. Maternal uniparental disomy was confirmed in one INAD case. CONCLUSIONS This is the largest report on PLAN in the Chinese population. We suggest that PLA2G6 should be screened in any patient exhibiting progressive gait disturbance, bradykinesia, dysarthria, tremors, mood/behavior changes or cognitive decline, especially when associated with cerebellar atrophy and/or iron accumulation and/or cerebral atrophy.

Abstract
Serological data provide an important measure of past exposure and immunity to hepatitis A virus (HAV) infection in a population. National serosurveys from developed countries have typically indicated a decline in HAV seroprevalence over time as sanitation levels improve. We examined trends in the seroepidemiology of HAV antibodies in Victoria, Australia, drawing on cross-sectional samples taken at three time points over a 20-year period. Stored sera from 1988 (n=753), 1998 (n=1091), and 2008 (n=791) from persons aged 1-69 years were obtained from the state of Victoria, Australia. The within-year population adjusted results show a significant trend of increasing population HAV seroprevalence over time from 34.3% (95% CI 31.7-36.9) in 1988, to 40.0% (95% CI 37.1-42.8) in 1998 and 55.1% (95% CI 52.1-58.1) in 2008, P<0.0001. A particularly noticeable rise in population seroprevalence was observed between 1998 and 2008 for those aged 5-39 years. The increase in HAV seropositivity over time is in contrast to the declining rates of disease notification in Australia. Based on comparisons with other Australian data, it appears the increase in population seroprevalence over the last two decades is unlikely to be due to endemic transmission of infection. Instead, other factors, including increases in travel to HAV endemic regions, migration to Australia from HAV endemic regions and vaccine uptake are more likely causes. Ongoing monitoring of serological HAV profiles in the population is required to determine future policy direction to prevent increased burden.

Abstract
Zeolite thin films were synthesized on the claddingless multimode portion of a singlemode-multimode-singlemode (SMS) fiber structure to construct a chemical vapor sensor. The zeolite-coated SMS structure was inserted into a fiber ring amplifier to produce a laser line. Combining the strong molecular adsorption capability of the nanoporous zeolite and the high signal-to-noise ratio of the fiber laser, the device was demonstrated for chemical vapor sensing with a low detection limit.

Abstract
PURPOSE The daily shifts of prostate gland have been intensively reported in literatures. However, few papers reported daily shifts of prostate bed due to several practical difficulties (e.g. limited soft tissue contrast in MVCT and CBCT and significant deformation of prostate cavity). We have routinely performed IGRT for both prostate gland and bed with ct-on-rails, and the superior image quality allows us not only to differentiate both bony anatomy and soft tissue contrast of prostate gland and bed. In this study, we investigated if the shift of prostate bed is signifiant difference from that of prostate gland. METHODS we reviewed shift data of 50 prostate gland patients who underwent 43 fractions and 22 patients of prostatectomy underwent 37 fractions. In total 2150 CT scans were reviewed for prostate gland and 814 scans for prostate bed. RESULTS Of the reviewed 814 CT images from 22 prostate bed patients, the standard deviation of shift was found to be 5.9 mm in AP direction (ranges from -22.4mm to 22mm), 3.2mm in SI direction (ranges from -14mm to 14mm), and 4.1mm in lateral direction (ranges from -15mm to 22mm). Of the 2150 CT images of prostate gland from 50 patients, the standard deviation of the shift was found to be 5.4 mm in AP direction (-20mm to 18 mm), 5.0mm in SI direction (-26mm to 20mm), and 4.3mm in lateral direction (range from-15 to 30mm). F tests of systematic /random shift distribution in three orthogonal directions between prostate gland and prostate bed were subsequently performed, it was found that the systematic shift in SI direction for prostate bed is smaller than for prostate gland (p=0.003). CONCLUSIONS Our result suggests no significant difference existing in shift between prostate bed and gland. Therefore strategies for daily prostate gland motion can be directly applied to prostate bed.

Abstract
AIMS/HYPOTHESIS Increased arterial stiffness is a risk factor for adverse cardiovascular events in adults with obesity-related insulin resistance (IR) or type 2 diabetes mellitus. Adolescents with type 2 diabetes have stiffer vessels. Whether stiffness is increased in obesity/IR in youth is not known. We sought to determine if IR was a determinant of arterial stiffness in youth, independent of obesity and cardiovascular risk factors. METHODS We measured cardiovascular risk factors, IR, adipocytokines and arterial stiffness (brachial artery distensibility [BrachD], pulse wave velocity [PWV]) and wave reflection (augmentation index [AIx]) in 343 adolescents and young adults without type 2 diabetes (15-28 years old, 47% male, 48% non-white). Individuals <85th percentile of BMI were classified as lean (n = 232). Obese individuals were grouped by HOMA index as not insulin resistant (n = 46) or insulin resistant (n = 65) by the 90th percentile for HOMA for lean. Mean differences were evaluated by ANOVA. Multivariate models evaluated whether HOMA was an independent determinant of arterial stiffness. RESULTS Risk factors deteriorated from lean to obese to obese/insulin resistant (all p ≤ 0.017). Higher AIx, lower BrachD and higher PWV indicated increased arterial stiffness in obese and obese/insulin-resistant participants. HOMA was not an independent determinant. Age, sex, BMI and BP were the most consistent determinants, with HDL-cholesterol playing a role for BrachD and leptin for PWV (AIx R²= 0.34; BrachD R² = 0.37; PWV R² = 0.40; all p ≤ 0.02). CONCLUSIONS/INTERPRETATION Although IR is associated with increased arterial stiffness, traditional cardiovascular risk factors, especially obesity and BP, are the major determinants of arterial stiffness in healthy young people.

Abstract
MicroRNAs (miRNAs) processed from nuclear-encoded transcripts control expression of target transcripts by directing cleavage or translational inhibition. Artificial miRNAs (amiRNAs) that exploit this endogenous gene silencing mechanism can be designed to target any gene of interest and provide a highly specific approach for effective post-transcriptional gene silencing (PTGS) in plants. Here, using Arabidopsis thaliana miR159a, miR167b and miR171a precursors as backbones, we designed two types of amiRNA targeting sequence that encode the silencing suppressor HC-Pro of Potato virus Y (PVY) and the TGBp1/p25 (p25) of Potato virus X (PVX). The detected amiRNAs efficiently inhibited HC-Pro and p25 gene expression and conferred highly specific resistance against PVY or PVX infection in transgenic Nicotiana tabacum; this resistance was also maintained under conditions of increased viral pressure. Moreover, resistance was strongly influenced by the complementarity between the target sequence and amiRNA, and was well correlated to amiRNA expression level; the expression level of amiRNAs was also well related to the precursor backbones. We further showed that transgenic N. tabacum developed highly effective resistance to both PVY and PVX through expression of a dimeric amiRNA precursor. Together, our findings indicate that transgenic plants with multiple virus-specific resistance can be obtained through co-expression of several amiRNAs targeting multiple viruses.

Abstract
BACKGROUND Recurrence is a major factor leading to treatment failure and death in gastric cancer (GC) patients following surgical resection. Importantly, the prediction of recurrence is critical in improving clinical outcomes. We isolated a group of microRNAs (miRNAs) and evaluated their usefulness as prognostic markers for the recurrence of GC. PATIENTS AND METHODS A total of 65 GC patients were selected for systematic analysis, 29 patients with recurrence and 36 patients without recurrence. Firstly, miRNAs microarray and bioinformatics methods were used to characterize classifiers from primary tumor samples (n = 8). Following, we validated these predictors both in frozen fresh and paraffin-embedded tissue samples (n = 57) using quantitative PCR. RESULTS We have identified 17 differential miRNAs including 10 up-regulated and 7 down-regulated miRNAs in recurrence group. Using k-top scoring pairs (k-TSP) method, we further ascertained hsa-miR-375 and hsa-miR-142-5p as a classifier to recognize recurrence and nonrecurrence cases both in the training and test samples. Moreover, we validated this classifier in 34 frozen fresh tissues and 38 paraffin-embedded tissues with consistent sensitivity and specificity with training set; among them, 15 cases were matched. A high frequency recurrence and poor survival were observed in GC cases with high level of hsa-miR-375 and low level of hsa-miR-142-5p (P < 0.001). In addition, we evaluated that hsa-miR-375 and hsa-miR-142-5p were involved in regulating target genes in several oncogenic signal pathways, such as TP53, MAPK, Wnt and vascular endothelial growth factor. CONCLUSION Our results indicate that the combination of hsa-miR-375 and hsa-miR-142-5p as a predictor of disease progression has the potential to predict recurrence risk for GC patients.
