Abstract
This systematic review and meta-analysis aimed to quantify weight gain after smoking cessation and the difference in weight gain between quitters and continuing smokers. Five electronic databases were searched before January 2015. Population-based prospective cohort studies were included if they recorded the weight change of adult smokers from baseline (before smoking cessation) to follow-up (at least 3 months after cessation). Thirty-five cohort studies were identified, including 63,403 quitters and 388,432 continuing smokers. The mean weight gain was 4.10 kg (95% confidence interval [CI]: 2.69, 5.51) and body mass index (BMI) gain was 1.14 kg m(-2) (95% CI: 0.50, 1.79) among quitters. Compared with continuing smoking, quitting smoking was significantly associated with absolute weight (adjusted mean difference [MD]: 2.61 kg; 95% CI: 1.61, 3.60) and BMI gain (adjusted MD: 0.63 kg m(-2) ; 95% CI: 0.46, 0.80). Subgroup analyses using geographic region found that the difference in weight gain was considerably greater in studies from North America than from Asia. Follow-up length was identified as a source of heterogeneity, such that studies with longer follow-up showed greater difference in weight gain. Effective strategies are needed to encourage smokers to quit irrespective of potential weight gain and to help quitters avoid excess weight gain.

Abstract
AIM We aimed to assess the relationships of patient education with the severity of treatment-induced side effects, daily calorie and protein intake, psychological status, and performance status in patients with lung cancer. METHODS The study patients were divided into an intervention (n = 62) and a control group (n = 110). The patients in the intervention group were provided with information about treatment, diet, and rehabilitation during chemotherapy. The patients in the control group were not specially provided with that information. RESULTS We observed significant differences between the intervention and control groups with respect to low daily protein intake (54.84% vs. 70.00%, p = 0.046), prevalence of depression (51.61% vs. 70.91%, p = 0.011), prevalence of severe side effects of treatment (14.52% vs. 37.27%, p = 0.002), and good performance status (75.81% vs. 55.45%, p = 0.008). CONCLUSIONS Our results suggest that educating patients about cancer treatment and rehabilitation can lead to increased protein intake, a lower prevalence of depression, lesser side effects from cancer treatments, and improved performance status.

Abstract
AIMS The prevalence of subclinical hypothyroidism (SCH) is high among patients with diabetes, although the relationship between SCH and diabetic vascular complications is unknown. This study aimed to determine the relationship between SCH and vascular complications in patients with Type 2 diabetes. METHODS In this cross sectional study, 991 patients with Type 2 diabetes were screened for thyroid function at their admission to the Second Affiliated Hospital of Chongqing Medical University. We compared the prevalence of coronary heart disease (CHD), ischaemic stroke and chronic kidney disease (CKD) with the prevalence of euthyroidism and SCH. RESULTS Among the 991 patients, 126 (12.7%) patients had SCH. The prevalence of CHD was significantly higher in the SCH group than in the euthyroid group (22.2% and 15.0%, respectively; P = 0.039). In the logistic regression analyses, SCH was associated with CHD [odds ratio (OR): 1.993; 95% confidence interval (CI): 1.135-3.497; P = 0.016]. This association was stronger in patients aged ≥ 65 years than in younger patients [2.474 (1.173-5.220); P = 0.017]. No significant association was found between SCH and ischaemic stroke. Patients with severe SCH had a high risk of CKD [1.842 (1.120-3.029); P = 0.016]. CONCLUSIONS This study provides evidence that SCH in patients with Type 2 diabetes is associated with a high prevalence of CHD (and CKD in severe SCH), although not with ischaemic stroke.

Abstract
The objective of this study was to evaluate the pharmacokinetic characteristics of enrofloxacin (ENR) injectable in situ gel we developed in dogs following a single intramuscular (i.m.) administration. Twelve healthy dogs were randomly divided into two groups (six dogs per group), then administrated a single 20 mg/kg body weight (b.w.) ENR injectable in situ gel and a single 5 mg/kg b.w. ENR conventional injection, respectively. High-performance liquid chromatography (HPLC) was used to determine ENR plasma concentrations. The pharmacokinetic parameters of ENR injectable in situ gel and conventional injection in dogs are as follows: MRT (mean residence time) (45.59 ± 14.05) h verse (11.40 ± 1.64) h, AUC (area under the blood concentration vs. time curve) (28.66 ± 15.41) μg·h/mL verse (11.06 ± 3.90) μg·h/mL, cmax (maximal concentration) (1.59 ± 0.35) μg/mL verse (1.46 ± 0.07) μg/mL, tmax (time needed to reach cmax ) (1.25 ± 1.37) h verse (1.40 ± 0.55) h, t1/2λz (terminal elimination half-life) (40.27 ± 17.79) h verse (10.32 ± 0.97) h. The results demonstrated that the in situ forming gel system could increase dosing interval of ENR and thus reduced dosing frequency during long-term treatment. Therefore, the ENR injectable in situ gel seems to be worth popularizing in veterinary clinical application.

Abstract
AIMS To compare the characteristics of the enteric-coated formulation of mycophenolate sodium (EC-MPS, myfortic) and mycophenolate mofetil (MMF, CellCept) given in combination with tacrolimus in Asian renal-transplant recipients. METHODS In a 24-month, single-centre, randomized, open-label, prospective study, 101 live-donor kidney transplant recipients were randomized to the EC-MPS (n = 50) or MMF (n = 51) group. The incidence of infection, therapeutic effect and adverse events were monitored. RESULTS The incidences of infection were 40% and 49% for the EC-MPS and MMF groups, respectively (p = 0.362). However, serious infection was only observed in the MMF group (11.8%; p = 0.027). The incidences of gastro-intestinal adverse events (GI AEs) were 24% and 41.2% for EC-MPS and MMF, respectively (p = 0.066). However, serious diarrhoea only occurred in the MMF group (9.8%; p = 0.056). The trough level of FK 506 at the time of diarrhoea (13.22 ± 3.66 ng/ml) was significantly higher than the level within 1 month before (9.18 ± 1.12 ng/ml; p < 0.05) and 1 month after diarrhoea (9.13 ± 0.85 ng/ml; p < 0.05). The infection rate of patients with diarrhoea was significantly higher than those without diarrhoea (68%, 39%, p = 0.024). The serum creatinine level was 698 ± 60 μmol/l for EC-MPS and 673 ± 68 μmol/l for MMF from baseline (p > 0.05), and it decreased to 66 ± 6 μmol/l for EC-MPS and 69 ± 8 μmol/l for MMF at 24 months (p > 0.05). The incidences of biopsy proven acute rejection (BPAR) were 20% and 25.5% for EC-MPS and MMF, respectively (p = 0.511). CONCLUSIONS Enteric-coated formulation of mycophenolate sodium, given in combination with tacrolimus, has a lower incidence of serious infection in Asian renal-transplant recipients compared with MMF, and the therapeutic effect of EC-MPS is similar to MMF. The clinical trial registration number is ChiCTR-IPR-14005509. The registry name is 'Effect of Enteric-coated mycophenolate sodium on posttransplant infection rate after renal transplantation compared with Mycophenolate mofetil'.

Abstract
Irisin is a newly discovered factor that is secreted by skeletal muscle and plays an important role in the homeostasis and metabolism of energy balance. This study used irisin radiolabeled with (125)I and small-animal SPECT/CT imaging to investigate the metabolic elimination and distribution of irisin in vivo. Irisin was labeled with (125)I using the Iodogen method. Small-animal SPECT/CT imaging was performed on C57/B16 mice at 15, 30, 60, 120, and 240 min after receiving a tail vein injection, and the radioactive distribution in the organs of mice was determined at 15, 60, and 120 min. Small-animal SPECT/CT imaging revealed the highest level of radioactivity in the gallbladder followed by the liver and kidney. Radioactivity decreased gradually with time in all organs. The radioactive distribution in the mice organs also showed that the highest %ID/g was in the gallbladder followed by the kidney and liver, and decreased gradually with time. The radioactivity in the gastric system reached its highest level at 60 min. Finally, our study showed the metabolic clearance of (125)I-irisin is achieved primarily through the hepatobiliary and renal system and provided the basis for the clinical application of irisin.

Abstract
This study investigated the molecular mechanism of the effect of sulfur dioxide (SO2) on the expression of adenosine triphosphate (ATP)-sensitive potassium ion (K+; KATP) channel, big-conductance calcium ion (Ca2+)-activated K+ (BKCa) channel, and L-type (L-Ca2+) channel subunits in rat aortas with quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blot. The results showed that the messenger RNA and protein levels of the KATP channel subunits Kir6.1, Kir6.2, and sulfonylurea receptor 2B (SUR2B) of rat aortas were significantly increased by SO2 at 14 mg/m3, whereas the levels of SUR2A were not changed. SO2 at all the treated concentrations markedly raised the expression of the BKCa channel subunits α and β1. SO2 at 14 mg/m3 significantly decreased the expression of the L-Ca2+ channel Cav1.2 and Cav1.3. The histological examination of rat aorta tissues showed moderate injury of tunica media in the presence of SO2 at 14 mg/m3. These suggest that SO2 can activate the KATP and BKCa channels by upregulating the expression of Kir6.1, Kir6.2, SUR2B, BKCa α, and BKCa β1, while inhibit the L-Ca2+ channels by downregulating the expression of Cav1.2 and Cav1.3 in rat aortas. The molecular mechanism of SO2-induced vasorelaxant effect might be linked to the changes in expression of these channel subunits, which plays an important role in the pathogenesis of SO2-associated cardiovascular diseases.

Abstract
PURPOSE We assessed the quality of life (qol) of nasopharyngeal carcinoma (npc) survivors with a survival time of more than 2 years in Fujian, China, and we analyzed factors influencing qol. METHODS We calculated the prevalence of psychological distress and radiotherapy (rt)-induced symptoms in 216 npc survivors who participated in a cross-sectional survey. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (version 3.0) was used to assess the qol of npc survivors. Multiple linear regression was applied to analyze the factors influencing qol. RESULTS The prevalence rates of rt-induced symptoms and psychological problems were 11.58% (95% ci: 7.21% to 15.58%) for difficulty in swallowing, 17.59% (95% ci: 12.51% to 22.67%) for mouth dryness or sores, 13.89% (95% ci: 9.28% to 18.50%) for nasal dryness or congestion, 18.52% (95% ci: 13.34% to 23.70%) for fatigue, 11.11% (95% ci: 6.92% to 15.30%) for frequent dizziness, 18.06% (95% ci: 12.93% to 23.19%) for decline in hearing, 14.81% (95% ci: 10.07% to 19.55%) for poor sleep quality, 18.52% (95% ci: 13.34% to 23.70%) for worry about disease recurrence, 18.98% (95% ci: 13.75% to 24.21%) for anxiety, and 25.00% (95% ci: 19.23% to 30.77%) for depression. Mean survival times were 4.32 ± 2.63 years in patients with mouth dryness or sores, 4.26 ± 2.90 years in patients with fatigue, and 5.60 ± 2.94 years in patients with a decline in hearing. The mean global qol score was 74.21 (95% ci: 72.22 to 76.20). At a significance level of α = 0.05, the factors influencing qol were age (p = 0.032), education level (p = 0.001), anxiety score (p < 0.001), depression score (p < 0.001), mouth dryness or sores (p < 0.001), fatigue (p = 0.027), and disease stage (p = 0.044). CONCLUSIONS The prevalence rates of mouth dryness or sores, fatigue, decline in hearing, depression, and anxiety were high in npc survivors with a survival time of more than 2 years. These rt-induced symptoms and psychological problems can last for many years after rt. The qol of the npc survivors was good. Factors influencing qol were age, education level, anxiety, depression, mouth dryness or sores, fatigue, and disease stage. Our results suggest that during clinical treatment, doctors should minimize the radiation dose to the ears of patients. In addition, our results emphasize the importance of providing oral and ear nursing and psychological care to npc survivors.

Abstract
The aim of the study was to evaluate the clinical value of serum high mobility group box chromosomal protein 1 (HMGB1) in ovarian cancer and analyze the correlation between HMGB1 and ovarian cancer clinicopathologic outcomes.A total of 105 patients with diagnosed epithelial ovarian cancer, 46 patients with ovarian benign disease and 33 healthy volunteers were enrolled from January 2011 through January 2013. Serum HMGB1 levels were analyzed by enzyme-linked immunosorbent assay.The mean value of serum HMGB1 levels in ovarian cancer patients (78.18±54.87ng/ml) was significantly higher than those in benign patients (33.98±9.97ng/ml) and healthy control (26.71±7.99ng/ml, p < 0.0001), respectively. The serum HMGB1 levels were 40.33±6.50ng/ml, 61.16±20.15ng/ml, 81.81±51.15ng/ml and 119.48±84.28ng/ml in patients with TNM stage I, II, III, and IV, respectively (p < 0.0001). There were 81 of the 105 ovarian cancer patients obtained complete remission, the serum HMGB1 levels before treatment(71.99±42.49ng/ml) were much higher than that at remission stage(42.10±15.48ng/ml) (p < 0.0001). During our investigating period, 28 ovarian cancer patients underwent recurrence, the serum HMGB1 levels were 75.54±39.50ng/ml in these recurrent ovarian cancer patients compared to 42.04±10.68ng/ml in non-recurrent ovarian cancer (p < 0.0001). None of the remission or recurrent patients came from benign ovarian tumor group.Our study suggests that HMGB1 may be a useful clinical marker for evaluating progression and predicting prognosis of ovarian carcinoma. Targeting HMGB1 production or release might have potential approaches for ovarian carcinoma treatment.

Abstract
BACKGROUND Previous studies summarized altered brain functional patterns in functional dyspepsia (FD) patients, but how the brain structural patterns are related to FD remains largely unclear. The objective of this study was to determine the brain structural characteristics in FD patients. METHODS Optimized voxel-based morphometry and tract-based spatial statistics were employed to investigate the changes in gray matter (GM) and white matter (WM) respectively in 34 FD patients with postprandial distress syndrome and 33 healthy controls based on T1-weighted and diffusion-weighted imaging. The Pearson's correlation evaluated the link among GM alterations, WM abnormalities, and clinical variables in FD patients. The optimal brain structural parameters for identifying FD were explored using the receiver operating characteristic curve. KEY RESULTS Compared to controls, FD patients exhibited a decrease in GM density (GMD) in the right posterior insula/temporal superior cortex (marked as pINS), right inferior frontal cortex (IFC), and left middle cingulate cortex, and an increase in fractional anisotropy (FA) in the posterior limb of the internal capsule, posterior thalamic radiation, and external capsule (EC). Interestingly, the GMD in the pINS was significantly associated with GMD in the IFC and FA in the EC. Moreover, the EC adjacent to the pINS provided the best performance for distinguishing FD patients from controls. CONCLUSIONS & INFERENCES Our results showed pINS-related structural abnormalities in FD patients, indicating that GM and WM parameters were not affected independently. These findings would lay the foundation for probing an efficient target in the brain for treating FD.

Abstract
BACKGROUND To investigate the similarities and differences in cerebral responses to puncturing at different acupoints for treating meal-related functional dyspepsia (FD). METHODS Twenty right-handed FD patients were enrolled and randomized divided into two groups. Each patient received 20 sessions' electro-acupuncture treatment. The acupoints used in Group A were four acupoints on the Stomach Meridian, and the acupoints used in Group B were four acupoints on the Gallbladder Meridian. PET-CT scans were performed before and after acupuncture treatment to record the changes of cerebral glycometabolism. KEY RESULTS After treatment, the dyspepsia symptoms and the quality of life (QOL) of the patients in each group were significantly improved (p < 0.05) and there was insignificant difference in efficacy between the two groups (p > 0.05). In Group A, deactivation in brainstem, bilateral anterior cingulate cortex (ACC) and cerebellum, left superior medial frontal gyrus, orbital frontal cortex (OFC), and thalamus, etc., and activation in bilateral middle cingulate cortex (MCC), precuneus and lingual gyrus, etc. were observed. In Group B, deactivation in brainstem, bilateral thalamus, putamen, ACC, postterior cingulate cortex, hippocampus and cerebellum, etc., and activation in bilateral MCC, precuneus, left OFC, etc. were observed (p < 0.05, Family-wise error corrected). CONCLUSIONS & INFERENCES Different acupoints have similar clinical efficacy but relatively different cerebral responses. The influence on the sensory transduction regions (brainstem and thalamus) and visceral modulation regions might be the common mechanism of different acupoints treating for FD, and the modulation on some emotion/cognition-related areas (e.g., prefrontal cortex) is the potential difference between the different acupoints.

Abstract
To reduce florfenicol (FFC) administration frequency in veterinary use, the drug was currently developed into in situ forming gel. Twelve pigs were randomly divided into two groups (six pigs per group). A single i.m. dose of 40 mg/kg body weight (b.w.) was given to pigs, group one was given FFC in situ forming gel, and group two was given FFC conventional injection. High-performance liquid chromatography (HPLC) was used to determine FFC plasma concentrations. There were significant differences (P < 0.01) between FFC in situ forming gel and conventional injection, in pharmacokinetic parameters MRT (mean retention time) (57.79 ± 2.88) h versus (15.94 ± 1.29) h, AUC (area under the concentration-time curve) (421.54 ± 8.97) μg·h/mL versus (168.16 ± 4.59) μg·h/mL, tmax (time of occurrence of cmax ) (9.00 ± 2.68) h versus (4.33 ± 0.82) h, cmax (maximum plasma concentration) (6.87 ± 0.66) μg/mL versus (12.01 ± 0.66) μg/mL, t1/2λz (terminal elimination half-life) (38.04 ± 2.20) h versus (9.15 ± 2.71) h. The results demonstrated that the in situ forming gel system could shorten dosing interval of FFC and thus achieved less frequent administration during long-term treatment.

Abstract
Skin plays an important role in innate immune responses to bacterial infection, but its molecular mechanism remains unclear in fish. The transcriptional profiling of the skin immune response to Aeromonas hydrophila infection of the zebrafish, Danio rerio (Hamilton), was performed by Affymetrix microarray analysis. The results showed that 538 genes were differentially expressed, of which 388 genes were up-regulated and 150 genes were down-regulated. The expression patterns for 106 representative genes were observed to be up-regulated in zebrafish skin at 24 and 36 h post-infection, and gene expression changes were clearly greater at 36 h. Gene Ontology classification indicated that 222 genes were significantly associated with the skin immunity, including complement activation, acute-phase response, stress response, chemotaxis and apoptosis. Further Kyoto Encyclopedia of Genes and Genomes analysis showed that the significant pathways included MAPK, p53, Wnt, TGF-β, Notch, ErbB, JAK-STAT, VEGF, mTOR and Calcium signalling in skin immune responses, and several genes (e.g. akt2l, frap1, nras, rac1, xiap) were found to be involved in signalling networks. Moreover, expression changes in nine selected genes were verified by real-time qPCR analysis. This is the first known report on transcriptome analysis in the skin of zebrafish against the pathogen A. hydrophila.

Abstract
This study aims to investigate the accuracy and value of multislice spiral computed tomography (MSCT) angiography in the evaluation of renal artery variation in living donor kidney transplantation. Two hundred seventy-three kidney transplantation donors underwent preoperative MSCT scanning. Two doctors determined the running direction and variation of the renal artery through joint analysis of the preoperative original MSCT image and the recombination image using the blind reading method, compared the imaging results with the intraoperative results, and evaluated the accuracy and application value of MSCT angiography in the evaluation of renal artery variation in living donor kidney transplantation. CT angiography (CTA) can better show the renal artery and its variation. A total of 52 accessory renal arteries were found in the 273 kidney transplant operations, whereas 55 accessory renal arteries were found in preoperative MSCT. Four accessory renal arteries indicated in the MSCT were not found during the operation, and one accessory renal artery found during the operation was not indicated in the preoperative MSCT. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of MSCT in the diagnosis of accessory renal arteries were 98.1, 98.2, 92.7, 99.5, and 98.2%, respectively. MSCT angiography can sensitively and accurately show the renal artery and its variation in living donor kidney transplantation, and has important clinical value for the formulation of the operative scheme before the transplantation.

Abstract
PURPOSE In the present study, we aimed to investigate the effects of chemotherapy-induced peripheral neurotoxicity (cipn) on psychological distress and sleep quality in cancer patients. METHODS A total of 706 cancer patients were interviewed for the study. In the 4th week of treatment, patient cipn was measured using the Patient Neurotoxicity Questionnaire (pnq). The sleep quality and psychological distress of patients were measured using the Pittsburgh Sleep Quality Index (psqi), the Distress Thermometer (dt), and the Hospital Anxiety and Depression Scale (hads). Multiple logistic regression was applied to determine the independent effects of cipn on psychological distress and sleep disturbance in the patients. RESULTS THESE CORRELATION COEFFICIENTS WERE OBTAINED: 0.387 (p < 0.0001) between the pnq total score and the dt score, 0.386 (p < 0.0001) between the pnq total score and the hads Depression score, 0.379 (p < 0.0001) between the pnq total score and the hads Anxiety score, and 0.399 (p < 0.0001) between the pnq total score and the psqi global score. The prevalence rates of distress, depression, anxiety, and poor sleep quality in the five pnq grades were statistically significantly different (p < 0.0001). After controlling for age, sex, education level, social supports, fatigue, disease stage, and tumour site, the pnq grades were found to be associated with depression (p < 0.0001), anxiety (p < 0.0001), and poor sleep quality (p < 0.0001). CONCLUSIONS Chemotherapy-induced peripheral neurotoxicity negatively affects psychological distress and sleep quality in cancer patients treated with chemotherapy. High pnq grades were significantly associated with poor psychological status and sleep quality. Our results emphasize the importance of assessing peripheral neuropathies during chemotherapy and of adjusting treatment plans based on assessment results.

Abstract
OBJECTIVE To develop a brief, reliable screening questionnaire for chronic obstructive pulmonary disease (COPD) for use in primary care settings. METHODS We developed a COPD Screening Questionnaire (COPD-SQ) using data collected from 19,800 subjects aged ≥40 years obtained from an epidemiological study of COPD in China in 2002 (Phase I). A stepwise logistic regression method was adopted for item reduction and scoring. We then assessed the COPD-SQ through a cross-sectional study (Phase II) among 3231 subjects aged ≥40 years. RESULTS The final COPD-SQ consisted of seven items: age, smoking pack-years, body mass index, cough, dyspnoea, family history of respiratory diseases and exposure to biomass smoke from cooking. Using the questionnaire to screen for COPD in Phase II, we obtained high classification accuracy with an area under the curve of 0.812 (95%CI 0.786-0.838). The sensitivity, specificity and correct classification rates for COPD diagnosis were respectively 60.6%, 85.2% and 82.7% at a cut-off score of 16. CONCLUSIONS The COPD-SQ can be used in first-level screening for COPD.

Abstract
BACKGROUND Association of de novo human leukocyte antigen (HLA) and major histocompatibility complex class I chain-related gene-A (MICA) antibodies and proteinuria with graft survival 5 years after renal transplantation. De novo presence of HLA and MICA antibodies after renal transplantation is associated with poor graft survival. Proteinuria after transplantation is also considered a risk factor for premature graft loss. In this study, we investigated the association of de novo HLA and MICA antibodies on proteinuria after renal transplantation and the association of proteinuria and de novo antibodies with graft survival. METHODS We enrolled 275 patients without preexisting HLA and MICA antibodies followed for >5 years after renal transplantation. All donor organs were from living-related donors or from an organ donation program. HLA and MICA antibodies were detected by the Luminex method. Patients with proteinuria (>150 mg/d) underwent intermittent 24-hour proteinuria examination. RESULTS The frequencies of de novo HLA and MICA antibody 5 years after transplantation were 25.8% and 12%, respectively. In total, 26.5% of patients had proteinuria at the 5-year follow-up. De novo HLA antibody was associated with increased proteinuria after transplantation (relative risk, 3.12). HLA antibody and proteinuria were both associated with poor 5-year graft survival (P = .027 and P = .006, respectively). CONCLUSION De novo HLA and MICA antibodies and proteinuria after renal transplantation are all associated with poor graft survival. De novo HLA antibody is independent risk factor for posttransplant proteinuria, and proteinuria affects the association of de novo antibodies with decreased graft survival after transplantation.

Abstract
Homocysteine (Hcy) is an independent risk factor of atherosclerosis through its involvement with the methionine cycle. In this study, we aimed to determine the blood vessel global methylation rate in Hcy-induced atherosclerosis in apolipoprotein-E-deficient (ApoE-/-) mice, and to explore the possible mechanism of this change in endothelial cells. ApoE-/- mice were divided into a hyperlipidemia (HLP) group, a hyperhomocysteinemia (HHcy) group, and an HHcy + folate + vitamin B12 (HHcy+FA+VB) group. Wild-type C57BL/6J mice were prepared as controls. Total Hcy, lipids, S-adenosylmethionine (SAM), and S-adenosylhomocysteine (SAH) contents in serum were measured with an automatic biochemistry analyzer and high-performance liquid chromatography. Methylation of B1 repetitive elements in blood vessels was tested using nested methylation-specific-polymerase chain reaction (nMS-PCR). Endothelial cells (ECs) were pretreated with Hcy or by adding FA and VB. Lectin-like oxidized LDL receptor-1 (LOX-1) expressions were determined by quantitative PCR, Western blot, and nMS-PCR. The HHcy group displayed severe HLP and HHcy. SAM and SAH contents were also elevated in the HHcy group compared with other groups. Methylation of B1 repetitive elements was significantly increased in the HHcy group (0.5050 ± 0.0182) compared to the HLP (0.5158 ± 0.0163) and control (0.5589 ± 0.0236) groups. mRNA and protein expressions of LOX-1 increased (0.2877 ± 0.0341, 0.6090 ± 0.0547), whereas methylation expression decreased (0.5527 ± 0.0148) after 100 μM Hcy stimulation in ECs. In conclusion, Hcy-induced atherosclerosis was closely associated with induced hypomethylation status in the blood vessel, and this process was partially mediated by LOX-1 DNA methylation.

Abstract
Long-acting injectable formulations of antipsychotics have been an important treatment option to increase the compliance of the patient with schizophrenia by monitoring drug administration and identifying medication noncompliance and to improve the long-term management of schizophrenia. Risperidone, a serotoninergic 5-HT2 and dopaminergic D2 receptor antagonist, was developed to be a long-acting sustained-release formulation for the treatment of schizophrenia. In this study, 12-week subchronic toxicity study of risperidone-loaded microspheres (RMs) in rats by intramuscular injection with an 8-week recovery phase was carried out to investigate the potential subchronic toxicity of a novel long-acting sustained-release formulation. The results indicated that the dosage of 10-90 mg/kg of RM for 2 weeks did not cause treatment-related mortality. The main drug-related findings were contributed to the dopamine D2 receptor and α1-adrenoceptor antagonism of risperidone such as elevation of serum and pituitary prolactin levels and ptosis and changes in reproductive system (uterus, ovary, vagina, mammary gland, testis, seminal vesicle, epididymis, and prostate). In addition, foreign body granuloma in muscle at injection sites caused by poly-lactide-co-glycolide was observed. At the end of the recovery phase, these changes mostly returned to normal. The results indicated that RM had a good safety profile in rats.

Abstract
BACKGROUND Increasing evidence shows central abnormalities in functional dyspepsia (FD) patients, but whether the symptom severity is directly reflected in altered brain patterns remains unclear. The purpose of this study was to explore how FD affected the resting functional brain patterns for different degrees of symptom severity. METHODS Functional magnetic resonance imaging was carried out in 40 FD patients and 20 healthy controls. The resting-state brain changes in regional homogeneity (ReHo) and seed correlation analysis were investigated in patients relative to controls. To what degree the brain changes reflected the severity of the disease was assessed by a pattern classification technique. KEY RESULTS Altered ReHo values (p < 0.05, FDR corrected) were discovered in multiple brain areas in FD patients, and only the anterior cingulate cortex (ACC) and thalamus exhibited significant correlation with the severity of dyspepsia symptoms. Compared with controls, the neural signal changes of the thalamus were not found in the less severe FD patient group but in the relatively more severe group, while the ACC showed aberrations in both groups. Seed-based correlation analysis revealed ACC- and thalamus-related functional connectivity differences between FD patients and controls at a voxel-wise level, and the altered thalamic circuits provided the best performance in distinguishing FD patients with different levels of symptom severity. CONCLUSIONS & INFERENCES Our results indicated that the functional abnormalities of the ACC and thalamus may occur at different clinical courses in FD. This may help us better understand the progression of FD.

Abstract
Anesthesia is a loss of sensation or consciousness and mechanisms by which drugs can produce this state are not clear. Recent studies gave insight show anesthetic agents may lead to loss of consciousness at the molecular level. The objective of this study was to determine whether ropivacaine can influence antioxidant defense system.To analyze the response of the antioxidant defense system to ropivacaine samples were taken from the vein before anesthesia (0 min) and 5 min, 15 min, and 60 min after anesthesia. Subsequently, the levels of lipid peroxidation as melaninedialdehyde (MDA) and glutathione (GSH), as well as superoxide dismutase (SOD) and catalase (CAT) activities were measured.We observed moderate increase in lipid peroxidation and glutathione levels. More-over, the activity of superoxide dismutase was slightly enhanced. These alterations occurred 5 min after spinal injection of ropivacaine and this phenomenon was maintained throughout anesthesia. We measured decreased catalase activity starting from 5 min after anesthesia and activity of this antioxidant enzyme was not recovered even after 60 min of anesthesia.We found that spinal injection of ropivacaine results in increased levels of free radicals in spinal fluid, which may stimulate antioxidant defense system of spinal fluid during anesthesia.

Abstract
BACKGROUND The Distress Thermometer (dt) is a screening tool recommended to quickly identify cancer patients with distress. Our study aimed to examine the sensitivity and specificity of the dt in detecting psychological distress in long-term Chinese nasopharyngeal cancer (npc) survivors. METHODS Data for the 442 participating npc survivors were collected through a self-administered questionnaire based on the dt and the Hospital Anxiety and Depression Scale (hads). The hads was used to define cases of psychological distress. Positive and negative groups were defined based on 4 hads criteria (Anxiety, Depression, Anxiety or Depression, and overall score). Receiver operating characteristic (roc) curves were used to examine the ability of all possible cut-off values of the dt to detect positive and negative cases. For each roc curve, the area under the curve (auc) was used as an indicator of the overall accuracy of the dt to identify positive cases of distress. RESULTS The positive auc values [with 95% confidence intervals (ci)] for the 4 hads criteria were 0.715 (95% ci: 0.667 to 0.764), 0.714 (95% ci: 0.661 to 0.768), 0.724 (95% ci: 0.677 to 0.771), and 0.724 (95% ci: 0.664 to 0.775) respectively. At a cut-off score of 4, the sensitivity of the dt to the four hads criteria was, respectively, 0.366 (95% ci: 0.296 to 0.436), 0.448 (95% ci: 0.364 to 0.532), 0.362 (95% ci: 0.299 to 0.425), and 0.421 (95% ci: 0.339 to 0.502), and the specificity of the dt to the 4 hads criteria was, respectively, 0.860 (95% ci: 0.818 to 0.902), 0.860 (95% ci: 0.821 to 0.899), 0.854 (95% ci: 0.814 to 0.894), and 0.854 (95% ci: 0.814 to 0.894). At a cut-off score of 5, the corresponding sensitivities were lower than those at the cut-off score of 4. All potential cut-off scores showed poor sensitivity (<0.90). CONCLUSIONS The roc analysis showed poor discrimination. No potential dt cut-off score had an acceptable sensitivity. The dt showed poor sensitivity in npc survivors. Thus, the dt might not be a valid scale for psychological distress screening in long-term Chinese npc survivors.

Abstract
The genetic diversity of 472 rice bean accessions (388 cultivated and 84 wild) from 16 Asian countries was evaluated by 13 simple sequence repeat (SSR) markers. In total, 168 alleles were detected, and the numbers of alleles in cultivated and wild accessions were 129 and 132, respectively. The gene diversity in cultivated populations (0.565) was about 83% of that for wild (0.678) populations. Cultivated populations from Vietnam, Myanmar, Nepal, and India had the highest gene diversity (>0.5). East Asian accessions formed a distinct genepool. Indonesian cultivated accessions showed high genetic divergence from other cultivated populations and had the most similar genetic structure to wild accessions. In Nepalese cultivated accessions, many accessions from western regions were quite distinct from others and formed a specific group. These Nepalese accessions could be considered a unique gene source for rice bean breeding. In contrast, eastern Nepalese accessions showed an SSR profile similar to that of Southeast Asian rice beans. The present study represents the first comprehensive SSR analysis in cultivated and wild rice bean germplasm and clarifies geographical distribution of genetic profile that might be used to broaden the genetic base of currently grown rice bean cultivars.

Abstract
BACKGROUND Although the regular consumption of green tea or green tea extract has been considered to improve insulin sensitivity, the reported results are inconsistent. Therefore, we conducted a meta-analysis to evaluate the effect of green tea or green tea extract on insulin sensitivity and glycaemic control in populations at risk of type 2 diabetes mellitus (T2DM). METHODS Electronic databases, including PUBMED, The Cochrane Library, EMBASE, ISI Web of Knowledge, Chinese Biomedical Literature Database and Chinese Scientific Journals Fulltext Database, were systematically searched to identify randomised controlled trials (RCTs) up to December 2011, supplemented by the Clinicaltrials.gov websites and the reference lists of identified studies. Two reviewers independently selected trials, extracted data, and evaluated the methodological qualities and evidence levels. RESULTS Seven RCTs involving 510 participants were identified. There was no statistically significant difference between green tea or green tea extract group and placebo group with regard to fasting plasma glucose [standardised mean difference (SMD) 0.04; 95% confidence interval (CI) -0.15 to 0.24], fasting serum insulin (SMD -0.09; 95% CI -0.30 to 0.11), 2-h plasma glucose in the oral glucose tolerance test (OGTT-2 h) (SMD -0.14; 95% CI -0.63 to 0.34), haemoglobin A₁c (SMD 0.10; 95% CI -0.13 to 0.33) and homeostasis model of insulin resistance (HOMA(IR)) index (SMD -0.06; 95% CI -0.35 to 0.23) in participants at risk of T2DM. CONCLUSIONS The consumption of green tea did not decrease the levels of fasting plasma glucose, fasting serum insulin, OGTT-2 h glucose, haemoglobin A₁c and HOMA(IR) in populations at risk of T2DM. Larger, longer-term and high-quality RCTs are needed to further definitely determine the effect of green tea or green tea extract on insulin sensitivity and glycaemic control in populations at risk of T2DM.

Abstract
Long-acting formulations of antipsychotics are important treatment options to increase the compliance of schizophrenic patients. Risperidone, a 5-HT2 and dopaminergic D2 receptor antagonist, was developed as long-acting sustained-release microspheres with poly(lactide-co-glycolide) (PLGA) as a drug carrier for the treatment of schizophrenia. In the present study, the main objective is to determine the nonclinical safety profile of risperidone-loaded microspheres (RM) in Beagle dogs after intramuscular administration for 3 months, once in 2 weeks, followed by 8-week recovery phase. No animal death was found and no special toxicological findings were observed. The findings, such as hypoactivity, ptosis, increased heart rate, and elevated serum and pituitary prolactin levels, were observed and related to the pharmacological effects of risperidone. The changes in the reproductive system (uterus, ovary, vagina, cervix, and mammary gland) were considered secondary to the prolactin elevation, and the congestion of spleen was related to risperidone. The foreign body granulomas at injection sites might be caused by PLGA. At the end of recovery phase, the above changes mostly recovered to normal, and on administering 3 mg/kg dose level once in 2 weeks on Beagle dogs showed no observed adverse effect. Taken together, RM had exhibited the acceptable safety.

Abstract
The measurement of J/ψ azimuthal anisotropy is presented as a function of transverse momentum for different centralities in Au+Au collisions at sqrt[s(NN)]=200 GeV. The measured J/ψ elliptic flow is consistent with zero within errors for transverse momentum between 2 and 10 GeV/c. Our measurement suggests that J/ψ particles with relatively large transverse momenta are not dominantly produced by coalescence from thermalized charm quarks, when comparing to model calculations.

Abstract
Breast cancer is a leading cause of cancer death among women, and the failure of normal apoptosis has been proved in the development of breast cancer. The phytoestrogen, calycosin, is extracted from Chinese medical herb Radix astragali. We recently reported that calycosin successfully stimulated proliferation of ER-positive MCF-7 human breast cancer cells at low concentration. In the present study, we assessed the proapoptotic function of calycosin in MCF-7 cells at high concentration in vitro, as well as the possible mechanism of its effect. MCF-7 cells were treated with different concentrations of calycosin, and then detected by MTT assay for cellular viability, Hoechst assay, and flow cytometry for apoptosis. RASD1 is identified as a Ras-family member and a regulator in MAPK-mediated cascade leading to cell proliferation or apoptosis. To provide insight into the functions of RASD1 signaling pathway in calycosin-induced apoptosis, the expression of Bcl-2, Bax, and RASD1 in calycosin-treated cells were determined by Western blot assay. The results showed that high concentrations of calycosin significantly suppressed the proliferation of MCF-7 cells and promoted cell apoptosis. Moreover, compared with control group, the expression of Bcl-2 decreased with calycosin in MCF-7 cells, while Bax increased, which was significantly correlated with elevated expression of RASD1. Together, we present evidence that at relatively high concentration calycosin triggered cell apoptosis through the mitochondrial apoptotic pathway by upregulating RASD1. And for the first time, this study revealed that calycosin may have potential as a therapeutic agent for the treatment of breast cancer.

Abstract
BACKGROUND Increasing brain imaging studies have emphasized the role of regional brain activity abnormalities in functional dyspepsia (FD) during the resting state. The goal of this study was to investigate the default mode network (DMN) in FD patients and healthy controls (HCs). METHODS Resting-state functional magnetic resonance imaging (fMRI) scanning was carried out on 49 patients and 39 HCs. Independent component analysis (ICA) was used to isolate the DMN in each subject. Group topography of the DMN was compared to study significant alteration in FD. A correlation analysis was then performed in the FD group to investigate the effects of symptom severity and the psychological factors on the DMN. KEY RESULTS Significant spatial differences with the DMN in FD patients, compared with HCs, were mainly found in the dorsomedial prefrontal cortex (dmPFC), ventromedial prefrontal cortex (vmPFC), orbitofrontal cortex (OFC), pregenual anterior cingulate cortex (pACC), thalamus, parahippocampal gyrus, precuneus, parietal cortex, and temporal pole. Meanwhile, Nepean Dyspepsia Index (NDI) scores were positively correlated with the pACC, and was negative correlated with the OFC. However, both the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores were not correlated with any regions of interest showing differences between the FD patients and the HCs. CONCLUSIONS & INFERENCES These findings suggested that the DMN might indeed undergo dysfunctional changes due to the abnormal persistent activity in FD patients. To a certain extent, the changes in the DMN were related to the FD-related symptom severity.

Abstract
Effects of processing variables on the structural gradients developed in the injection molding of thermotropic wholly aromatic copolyester parts were investigated using optical macro and microscopy combined with image analysis techniques at various sections of the molded LCP parts.
The studies indicate the existence of a multi-layer structure from skin to core of the parts. These include: a skin layer, a transition zone composed of a sub-skin layer, a shear layer and a core region. The effects of processing conditions including injection speed, mold temperature, and mold size on the structural features were evaluated. An interesting buckling phenomenon resembling features observed in jetting at core regions near the end of the cavity after the divergence section was observed for the samples molded at the lowest injection speed and mold temperature.
Digital image analysis of the images of the sectioned parts revealed that there are more layers than one observes macroscopically. In certain instances as many as 15 layers were detected. Orientation behavior and the positional light reflection intensity appear to correlate with each other particularly away from the skin regions. This may be the manifestation of high visible light absorption anisotropy exhibited by these aromatic polymers.

Abstract
Elliptic flow (v(2)) values for identified particles at midrapidity in Au + Au collisions, measured by the STAR experiment in the beam energy scan at RHIC at sqrt[s(NN)] = 7.7-62.4 GeV, are presented. A beam-energy-dependent difference of the values of v(2) between particles and corresponding antiparticles was observed. The difference increases with decreasing beam energy and is larger for baryons compared to mesons. This implies that, at lower energies, particles and antiparticles are not consistent with the universal number-of-constituent-quark scaling of v(2) that was observed at sqrt[s(NN)] = 200 GeV.
