Abstract
Objective: To investigate the clinicopathological features and molecular characteristics of β-catenin-deficient colorectal cancer. Methods: The clinical, pathological and molecular features of 11 colorectal cancers with β-catenin protein loss diagnosed at the 960th Hospital of People's Liberation Army of China, from January 2012 to November 2022 were analyzed. Results: Among the 11 patients, 3 were males and 8 were females. Their age ranged from 43 to 74 years, with the median age of 59 years. Six were in the left colon and 5 were in the right colon. One of the 11 cases had lymph node metastasis, 10 cases were well and moderately differentiated adenocarcinoma, and 1 was mucinous adenocarcinoma. Eight cases were of TNM stage T4, 2 of T1 stage and 1 of Tis stage. β-catenin protein was not detected using immunohistochemistry. Sanger sequencing revealed the presence of fragment-deletion mutation in exon 3 of CTNNB1 gene, resulting in loss of β-catenin protein expression. Conclusion: β-catenin deficiency is present in a small number of colorectal cancers and may be associated with exon 3 mutations of CTNNB1 gene.

Abstract
OBJECTIVES Patient safety incidents can impact not only patients and families but also healthcare providers, who may experience negative emotions and symptoms, such as anxiety, guilt, stress, and loss of confidence. To identify and support these "second victims," a screening tool called the Second Victim Experience and Support Tool (SVEST) has been developed. This scoping review aims to map our current knowledge of the SVEST in terms of its scope of use, validation and limitations. STUDY DESIGN Scoping review. METHODS In accordance with the framework outlined by Arksey and O'Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews, we conducted a literature search in MEDLINE, CINAHL, Cochrane Library, SCOPUS, Embase and PsycINFO databases from database inception up till 1 March 2023. RESULTS A total of 31 studies were reviewed. The SVEST has been cross-culturally adapted from English into other languages. The SVEST has been successfully used in different contexts and with various healthcare professionals, including doctors, nurses, allied health professionals, midwives and pharmacists. The tool has been used to assess the impact of second victim experiences and the effectiveness of support interventions in addressing the phenomenon. Validity assessment of translated versions of SVEST in the reviewed studies revealed good content validity in most cases, although some studies did not report clear values for scale-level Content Validity Index. On the whole, SVEST is generally a reliable and valid tool, although further refinements and modifications may improve its validity and reliability. CONCLUSIONS The review highlights the significance of SVEST as a crucial resource for healthcare providers and organisations that prioritise well-being and safety in health care. It also underscores the importance of recognising the needs of second victims and offering them appropriate interventions to manage the aftermath of adverse events.

Abstract
The composite material based on N-, S-, and Fe-doped TiO2 (NSFe-TiO2) synthesized by wet impregnation was used as a photocatalyst to rapidly degrade sulfadiazine. The photocatalytic degradation behavior and mechanism of sulfadiazine on NSFe-TiO2 were investigated for revealing the role of degradation under ultraviolet light. The results showed that compared with TiO2, NSFe-TiO2 markedly improved the efficiency in photocatalytic degradation of sulfadiazine: more than 90% of sulfadiazine could be removed within 120 min by NSFe-TiO2 dosage of 20 mg L-1. The process conformed to first-order reaction kinetics model. The parameters such as loaded amount of NSFe-TiO2, solution pH value, humic acid concentration and recycle numbers on removal efficiency were also studied. Compared to neutral and alkaline conditions, acidic condition was not conducive to the photocatalysis. HA, Ca2+, Cu2+ and Zn2+ in the actual water body had mild inhibition on sulfadiazine degradation in UV/NSFe-TiO2 system. Fragments screened by high-resolution mass spectrometry were conducted to explore the oxidation mechanism and pathways of sulfadiazine degradation. On the whole, UV/NSFe-TiO2 photocatalysis has a good effect on sulfadiazine removal.

Abstract
OBJECTIVES The relationship between sarcopenia and cognitive function has been extensively studied, but is usually explored at a single time point. We used repeatedly measured cognitive data to examine the relationship between sarcopenia and cognitive trajectories over time among middle-aged and older Chinese adults. DESIGN A nationally representative cohort study. SETTING AND PARTICIPANTS Data were from three waves (2011, 2013 and 2015) of the China Health and Retirement Longitudinal Study (CHARLS). A total of 8963 participants with complete baseline data (wave 1) and at least two cognitive function tests (waves 1-3) were enrolled in this study. MEASUREMENTS Sarcopenia was diagnosed at baseline (wave 1). The wave 1-3 data were used to analyze cognitive trajectories over time by constructing a latent class trajectory model (LCTM). Logistic regression model was used to analyze the association between sarcopenia and cognitive trajectories. RESULTS Among 8693 participants, we identified two trajectories of cognitive function development, including a persistent low trajectory (n= 4856, 55.86%) and a persistent high trajectory (n= 3837, 44.14%). Sarcopenia was associated with persistently low cognitive trajectory of global cognitive (OR: 1.248, 95%CI: 1.046-1.490) after adjustment for other covariates. This association was still observed when stratified by age, gender, educational level, marital status, social activity, smoking status and drinking status. Mediation analysis showed that body mass index (BMI) mediated efficacy accounting for 42.32% of the relationship. CONCLUSIONS Our study showed two trajectory groups of global cognitive function. Sarcopenia was associated with a persistent low trajectory over time and BMI mediated the relationship between sarcopenia and cognitive trajectories among middle-aged and older Chinese adults.

Abstract
Objective: To explore the application value of plasma heterogeneous nuclear ribonucleoprotein A2/B1(hnRNP A2B1), β-amyloid 42(Aβ42) and phosphorylated tau protein(P-tau) levels in elderly patients in the preoperative diagnosis of mild cognitive impairment(MCI). Methods: A total of 200 patients who underwent elective surgery at Tianjin Third Central Hospital from June 2020 to March 2021were Enrolled, regardless of gender, age 65-80 years old. According to the international MCI working group standards and the European Alzheimer's Disease Federation working group standards, patients were divided into MCI group and control group. There were 58 males and 42 females in each group. The patient's plasma hnRNP A2/B1, Aβ42 and P-tau levels were detected before operation. The sensitivity, specificity and accuracy of the diagnosis of MCI were calculated. The receiver operating characteristic curve were drew to evaluate the diagnostic value of each index. Results: The plasma levels of hnRNP A2/B1, Aβ42 and P-tau in the MCI group were 310.0 (275.1, 344.2), 34.5 (24.9, 42.5), 190.4 (150.4, 301.7) ng/L, respectively, which were significantly higher than those of the control group [272.7 (239.6, 291.5), 18.7 (14.7, 26.6), 140.0 (101.8, 217.5) ng/L]. The differences were statistically significant (all P<0.05). Taking the international MCI working group standard as the gold standard, the sensitivity, specificity and area under the ROC curve (AUC) of plasma hnRNP A2/B1 for predicting MCI were 80%, 61%, and 0.781, respectively. The sensitivity, specificity and AUC of plasma Aβ42 for predicting MCI were 78%, 73%, and 0.744. The sensitivity, specificity, and AUC of P-tau for predicting MCI were 51%, 79%, and 0.675, respectively. The sensitivity, specificity and AUC of hnRNP A2/B1 and Aβ42 in predicting MCI were not statistically significant (all P>0.05), but the sensitivity of both were higher than P-tau (all P<0.001). Compared with P-tau, the AUC of plasma hnRNP A2/B1 was higher when predicting MCI (P<0.05). When the three indicators were combined, the sensitivity was 82%, and the AUC was 0.842, both of which were the highest, but the specificity reduced (71%) (all P<0.05). Conclusions: Plasma hnRNP A2/B1 combined with Aβ42 and P-tau levels can improve the sensitivity and accuracy of MCI diagnosis in elderly MCI patients before surgery, and have the greatest diagnostic efficiency. It has certain application value.

Abstract
Objectives: To evaluate the effect of a musculoskeletal ultrasound programme (MUSP) applying real-time ultrasonography with reinforcement of findings by a rheumatologist on improving disease-modifying anti-rheumatic drugs (DMARDs) adherence in rheumatoid arthritis (RA).Method: Eligible RA patients with low adherence score (< 6) on the 8-item Morisky Medication Adherence Scale (MMAS-8) were randomized to either an intervention group (receiving MUSP at baseline) or a control group (no MUSP), and followed up for 6 months. Adherence measures (patient-reported and pharmacy dispensing records) and clinical efficacy data were collected. The MUSP's feasibility and acceptability were assessed.Results: Among 132 recruited RA patients, six without baseline visits were excluded; therefore, 126 patients were analysed (62 intervention and 64 control). The primary outcome (proportion of patients with 1 month MMAS-8 score < 6) was significantly smaller (p = 0.019) in the intervention (35.48%) than the control group (56.25%). However, 3 and 6 month adherence and clinical efficacy outcomes were not significantly different between the two groups (all p > 0.05). All 62 patients completed the MUSP (mean time taken, 9.2 min), with the majority reporting moderately/very much improved understanding of their joint condition (71%) and the importance of regularly taking their RA medication(s) (79%). Most patients (90.3%) would recommend the MUSP to another RA patient.Conclusions: The MUSP improved RA patients' DMARDs adherence in the short term and was feasible and well accepted by patients. Future studies could evaluate whether repeated feedback using MUSP could help to sustain the improvement in DMARD adherence in RA patients, and whether this may be clinically impactful and cost-effective.

Abstract
Background:To facilitate earlier diagnosis of spondyloarthritis (SpA), we have previously cross-culturally adapted a self-administered screening questionnaire.Objectives:We aimed to improve the sensitivity of this questionnaire as a screening tool by comparing various scoring methods.Methods:Subjects newly referred to a rheumatology clinic self-administered the questionnaire before seeing a rheumatologist. Identification of axial SpA by the questionnaire using original scoring (Method A) and scoring based on Assessment of SpondyloArthritis International Society (ASAS) inflammatory back pain (IBP) criteria (Method B), ASAS referral criteria (Method C), ASAS classification criteria (Method D) and a combination of ASAS referral and classification criteria (Method E) were compared to classification by the ASAS classification criteria and diagnosis by rheumatologist. Since Methods B-E were based on SpA features, we compared self-reported vs rheumatologist-documented features in subjects with axial SpA.Results:Of 1418 subjects (age: 54 ± 14 years, female: 73%), 39 were classified as axial SpA cases by classification criteria. Methods A-E yielded sensitivities of 39%, 72%, 67%, 49% and 85%, respectively, among patients newly referred to the rheumatology clinic (Table 1). Rheumatologist-documented clinical SpA features exceeded self-report for IBP (62 vs 44%) and uveitis (15 vs 5%). The reverse was true for arthritis (21 vs 80%), enthesitis (28 vs 33%), dactylitis (3 vs 18%), good response to NSAIDs (33 vs 41%) and family history for SpA (5 vs 10%).Table 1.Performance of the five scoring methods for the cross-culturally adapted Hamilton axial SpA questionnaire.Scoring methodSensitivity(95% confidence interval)Specificity(95% confidence interval)Positive predictive value(95% confidence interval)Negative predictive value(95% confidence interval)Method A38.5(23.4 – 55.4)93.7(92.3 – 94.9)14.7(8.5 – 23.1)98.2(97.3 – 98.8)Method B71.8(55.1 – 85.0)73.1(70.7 – 75.4)7.0(4.7 – 10.0)98.9(98.1 – 99.5)Method C66.7(49.8 – 80.9)77.8(75.5 – 80.0)7.8(5.2 – 11.3)98.8(98.0 – 99.4)Method D48.7(32.4 – 65.2)74.9(72.5 – 77.2)5.2(3.2 – 8.0)98.1(97.1 – 98.8)Method E84.6(69.5 – 94.1)37.2(34.6 – 39.8)3.7(2.5 – 5.1)98.8(97.5 – 99.6)Method A: the original scoring defined by the questionnaire developers; Method B: a scoring based on the ASAS IBP criteria; Method C: a scoring based on the ASAS referral criteria; Method D: a scoring based on the ASAS classification criteria for axial and peripheral SpA; Method E: a scoring based on a combination of the ASAS referral and classification criteria.Conclusion:A self-administered questionnaire scored based on a combination of ASAS referral and classification criteria achieved high sensitivity in identifying axial SpA in subjects referred to a rheumatology clinic.

Abstract
INTRODUCTION Chronic hepatitis B (CHB) remains common in endemic regions, causing significant healthcare burden. Patients with CHB may need to be adherent to nucleoside analogue (NA) for a long period of time to prevent complications. This study aims to investigate the safety, efficacy and patient experience of a virtual monitoring clinic (VMC) in monitoring stable patients taking NA for CHB. METHODS Patients on NA and regular follow-up were randomised to either VMC alternating with doctors' clinic visit or to a control group in which they continued standard follow-up by doctors. Therapy adherence was measured by medication possession ratio (MPR) for NA therapy, incidence of virological breakthrough and hepatocellular carcinoma (HCC) development at two years of follow-up. Patient acceptance was measured on a Likert scale of 1-10. RESULTS A total 192 patients completed follow-up: 94 and 98 patients in the VMC and control groups, respectively. Mean age was 60.6 ± 10.8 years, with 95.3% Chinese ethnicity and 64.1% males. Age, gender, race, educational, employment and financial status were similar in both groups. Upon study completion, the majority of patients - 76 (80.9%) in VMC group and 74 (75.5%) in control group - had MPR ≥0.8; 88.8% were satisfied and rated VMC better than a traditional follow-up clinic with doctors only. More than 85% of patients rated ≥8/10 on the Likert scale for VMC, and preferred VMC over traditional clinic visits. Clinical outcomes observed were HCC development in one (1.1%) in the VMC group and four (4.1%) in the control group (p = 0.369). Two (2.1%) and one (1.0%) virological breakthroughs were observed in the VMC and control groups, respectively (p = 0.615). No incidence of HCC or abnormal blood tests were missed in the VMC arm. DISCUSSION VMC is a viable and safe clinical model for monitoring stable CHB patients on NA therapy without compromising patients' adherence to medications and is preferred by patients.

Abstract
BACKGROUND The purpose of this study was to explore the correlation of anxiety and depression with therapeutic response to etanercept in psoriasis patients. PATIENTS AND METHODS One hundred and thirty-three patients with moderate-to-severe plaque psoriasis undergoing etanercept treatment were consecutively enrolled in this prospective cohort study, with all patients receiving etanercept treatment for 6 months. Psoriasis Area and Severity Index (PASI) score was evaluated at baseline (M0) and at month 1 (M1), M3 and M6 after treatment, and PASI 75/90 responses were calculated. The Hospital Anxiety and Depression Scale-Anxiety (HADS-A) score and the HADS-Depression (HADS-D) score were used to evaluate patients' anxiety and depression at M0, M1, M3 and M6. Sustained anxiety/depression were defined as HADS-A/D score≥8points both at M0 and M1. RESULTS Female gender and higher PASI score were associated with high risk of anxiety, while female gender, higher PASI score and longer disease duration were correlated with increased depression risk. After 6 months of etanercept treatment, 65.4% and 36.1% patients achieved PASI 75 and PASI 90 responses respectively, and both HADS-A and HADS-D scores were decreased. Most importantly, no correlation of baseline anxiety and depression with PASI 75 or PASI 90 response after 6 months of treatment was noted, while sustained depression, though not sustained anxiety, was observed to be correlated with decreased PASI 75 and PASI 90 responses. CONCLUSIONS Etanercept reduces anxiety and depression in psoriasis patients, and sustained depression correlates with reduced therapeutic response to etanercept.

Abstract
Empty follicle syndrome (EFS) is a disorder associated with female infertility and presents as a complete failure to retrieve oocytes during ART cycles despite normal follicle development and careful aspiration. To date, only two EFS cases have been reported with homozygous missense mutations in the luteinizing hormone/chorionic gonadotropin receptor (LHCGR) gene, and both cases showed normal estradiol (E2) production during ovulation induction. The molecular genetic mechanisms of EFS remain unknown. Herein, we report two novel homozygous inactivating LHCGR mutations, c.736 C>T (p.Q246*) and c.846dupT (p.R283*), in two female EFS patients from unrelated consanguineous families. The probands had impaired E2 production during the ART process, which differs from previously reported EFS cases. The inactivating mutations not only led to EFS in the two female probands, but also resulted in 46, XY disorder of sex development (46, XY DSD) in their male siblings. As far as we know, this is the first report of LHCGR mutations leading to both EFS and 46, XY DSD within the same pedigree. Our findings provide researchers and clinicians with a better understanding of phenotype-genotype correlations between EFS and 46, XY DSD and the LHCGR gene.

Abstract
OBJECTIVE The aims of the current study were to assess the prevalence of overweight and obesity by four different references and to explore the characteristics of adolescent overweight and obesity in Chinese secondary school students aged 12-18 years. STUDY DESIGN A cross-sectional study was conducted in this study. METHODS Using stratified random cluster sampling, 8999 secondary school students were enrolled. The references developed by Must and Dallal and Dietz, the Childhood Obesity Working Group of the International Obesity Task Force, the US Centers for Disease Control and Prevention, and the Group of China Obesity Task Force (GCOTF reference) were used to identify overweight and obese students. RESULTS The prevalence of adolescent overweight and obesity vary substantially based on the four references. The prevalence of adolescent overweight and obesity based on GCOTF reference are 8.4% and 4.1%, respectively, which is significantly lower than the prevalence of overweight and obesity in their peers in 2000 (χ2 = 24.03, P < 0.01). The prevalence of overweight and obesity in boys are 12.0% and 5.7%, which are higher than those in girls, 4.6% and 5.7% (χ2 = 240.68, P < 0.01). The prevalence of overweight and obesity in singletons are higher than those in non-singletons (χ2 = 40.25, P < 0.01). The prevalence of overweight and obesity in students with lower school community ladder of subjective social status are higher than those from higher ones (χ2 = 21.61, P < 0.01). CONCLUSION The GCOTF reference is more suitable for screening overweight and obesity in Chinese adolescents. The current prevalence rates of adolescent overweight and obesity decreased, and girls made a tremendous contribution to this decreasing trend. Singletons and adolescents in lower school community ladder of subjective socio-economic status may be at higher risk of getting overweight and obesity. More effective strategies with full consideration to the characteristics above should be developed to control and prevent adolescent overweight and obesity.

Abstract
Objective: To evaluate and explore the mechanism of the effect of hypertonic pre-injection on postoperative delirium in the aged. Methods: From June 2016 to February 2017, participants scheduled hip arthroplasty surgery were randomly divided into four groups: Group 1 (H1) 30 patients pre-injected 4 ml/kg hypertonic solution were proceeded general anesthesia; Group 2 (H2) 30 patients pre-injected 4 ml/kg hypertonic solution were proceeded spinal canal anesthesia; Group 3 (C1) 30 patients pre-injected 4 ml/kg isotonic saline were proceeded general anesthesia; Group 4 (C2) 30 patients pre-injected 4 ml/kg isotonic saline were proceeded spinal canal anesthesia in Department of Anesthesiology, Third Hospital of Hebei Medical University.All these patients were operated after anesthesia.To avoid electrolyte disorder, the level of Na(+) , Ca(2+) , K(+) in the artery blood was analyzed.Peripheral venous blood was extracted to detect the concentration of inflammatory factors IL-1β, IL-6, IL-10, TNF-α and nerve injury factor S100β.In order to evaluate the relationship of these inflammatory fators with monocyte, we used flow cytometry to detect the number of mononuclear in peripheral venous blood.After operation 1 to 3 days, all these patients were assessed cognitive function by Nu-DESC. Results: Electrolytes fluctuationed in the normal range in four groups at different time points.Compared with before infusion, IL-6, IL-1β and TNF-α of four groups were significantly increased in postoperative.Compared with group H(H1 or H2), IL-1β, IL-6 and TNF-α were increased and IL-10 was decreased in group C(C1 or C2) after the surgery.S100β of group C(C1 and C2) was higher than before infusion.No significant changes were found in the cotykines mentioned above between group H1 and H2. The expression of monocytes CD14(+) CD16(+) /CD14(+ +) was decreased and the incidence of postoperative delirium was lower in group H than group C(13.3%, 10.0% vs 33.3%, 36.7%, P<0.05). Conclusion: Hypertonic saline can improve postoperative delirium of the aged and the mechanism may be related to the inhibition of monocyte cells secreting inflammatory factors.

Abstract
AIM Adult growth hormone deficiency (AGHD) refers to decreased secretion of growth hormones in the adults, which is associated with increased clustering of conventional cardiovascular risk factors such as central obesity, insulin resistance and dyslipidemia. Metabolic syndrome (MetS), a recognized risk factor of cardiovascluar diseases, shares some clinical features. Given that the prevalence of MetS is on the rise in patients with AGHD, and that cardiovascular disease (CVD) is an important cause of morbidity and mortality in that population, the alternative, simple, non-invasive methods of assessing MetS among this population are needed. This study aims to determine the sensitivity of five anthropometric indices [Body mass index (BMI), Waist circumference (WC), Waist-to-hip ratio (WHR), Waist-to-height ratio (WHtR) and Visceral adiposity index (VAI)] in predicting metabolic syndrome in Chinese population-based patients with adult growth hormone deficiency. MATERIALS AND METHODS A total of 96 Chinese patients with adult growth hormone deficiency were included in this study. They were compared with equal number of apparently healthy persons with similar characteristics (matched with age and gender) to the previous group. Anthropometric measurements including weight, height, serum lipids indices, blood pressure (BP), fasting plasma glucose (FPG), WC were measured. BMI, WHR, WHtR, and VAI were calculated. RESULTS AND DISCUSSION AGHD patients with MetS had higher WC (91.00 ± 8.28 vs 78.01 ± 7.12), BMI (24.95 ± 2.91 VS 23.30 ± 2.80), WHR (0.92 ± 0.06 VS 0.87 ± 0.07), WHtR (0.53 ± 0.06 VS 0.47 ± 0.05), VAI [(5.59 (4.02, 7.55) VS 1.69 (0.87, 3.05)] levels in comparison to those without MetS. Meantime WC, BMI, WHR, WHtR, VAI was positively correlated to MetS components. ROC curve for participants with AGHD showed that VAI had the highest SS of 92% (BMI 0.812; WHR 0.706; WHtR 0.902; VAI 0.920, respectively) for prediction of MetS in AGHD. The optimal cutoff values for different adiposity markers in predicting MetS were as follows: WC (79.65), BMI (23.46); WHR (0.89); WHtR (0.54); VAI (2.29). CONCLUSION In conclusion, our study showed all adiposity measures of interest present themselves as easy and practical tools for use in population studies and clinical practice for evaluating MetS in AGDH and VAI was identified as the best in Chinese AGHD patients among them.

Abstract
Cotton plants accumulate phytotoxins, such as gossypol and related sesquiterpene aldehydes, to resist insect herbivores. The survival of insects exposed to toxic secondary metabolites depends on the detoxification metabolism mediated by limited groups of cytochrome P450. Gossypol has an antibiotic effect on Aphis gossypii, and as the concentrations of gossypol were increased in the present study, the mortality of cotton aphids increased from 4 to 28%. The fecundity of the cotton aphids exposed to gossypol was also significantly reduced compared with the control. The transcriptional levels of CYP6DA2 in cotton aphids were significantly induced when exposed to gossypol, and knockdown of the CYP6DA2 transcripts by RNA interference (RNAi) significantly increased the toxicity of gossypol to cotton aphids. To further understand the gossypol regulatory cascade, the 5'-flanking promoter sequences of CYP6DA2 were isolated with a genome walker, and the promoter was very active and was inducible by gossypol. Co-transfection of the cap 'n' collar isoform C (CncC) and CYP6DA2 promoters dramatically increased the expression of CYP6DA2, and suppression of the CncC transcripts by RNAi significantly decreased the expression levels of CYP6DA2, and significantly increased the toxicity of gossypol to cotton aphids. Thus, the transcriptional regulation of CYP6DA2 involved the transcriptional factor CncC.

The purpose of the emerging field of phenomics is to systematically determine and measure phenotypes across biology for the sake of understanding. Phenotypes can affect more than one cell type and life stage, so ideal phenotyping would include the state of every cell type within the context of both tissue architecture and the whole organism at each life stage. In medicine, high-resolution anatomic assessment of phenotype is obtained from histology. Histology's interpretative power, codified by Virchow as cellular pathology, is derived from its ability to discern diagnostic and characteristic cellular changes in diseased tissues. Cellular pathology is observed in every major human disease and relies on the ability of histology to detect cellular change in any cell type due to unbiased pan-cellular staining, even in optically opaque tissues. Our laboratory has shown that histology is far more sensitive than stereomicroscopy for detecting phenotypes in zebrafish mutants. Those studies have also shown that more complete sampling, greater consistency in sample orientation, and the inclusion of phenotypes extending over longer length scales would provide greater coverage of common phenotypes. We are developing technical approaches to achieve an ideal detection of cellular pathology using an improved form of X-ray microtomography that retains the strengths and addresses the weaknesses of histology as a screening tool. We are using zebrafish as a vertebrate model based on the overlaps between zebrafish and mammalian tissue architecture, and a body size small enough to allow whole-organism, volumetric imaging at cellular resolution. Automation of whole-organism phenotyping would greatly increase the value of phenomics. Potential societal benefits would include reduction in the cost of drug development, a reduction in the incidence of unexpected severe drug and environmental toxicity, and more rapid elucidation of the contributions of genes and the environment to phenotypes, including the validation of candidate disease alleles identified in population and personal genetics.

Abstract
BACKGROUND AND OBJECTIVE A new combination contraceptive tablet containing 0.02 mg ethinyl estradiol (EE) and 0.10 mg levonorgestrel (LNG) with potential advantages has been developed in China. This study was aimed to describe the pharmacokinetic characteristics of this new combination contraceptive tablet in female Chinese volunteers. METHODS This study was designed as phase I, open-label, and one-sequence clinical trial. 12 healthy nonpregnant female Chinese volunteers received a single dose (1 tablet) and multiple dose (1 tablet per day) administration for 21 consecutive days under fasting condition. Blood samples were analyzed with 2 validated LC-MS/MS methods for EE and LNG, respectively. RESULTS AND CONCLUSION After the single dose administration, the C max of EE and LNG were 44.76±18.64 pg/mL and 2.256±1.008 ng/mL, respectively. The steady-state condition of EE was achieved on the 6(th) day after the beginning of the multiple dose administration, while the steady-state condition of LNG was achieved on the 21(st) day. For EE, the mean MRT 0-72 and t 1/2 increased by 40.2 and 30.6%, meanwhile the mean Cl/F and Vd/F decreased by 18.5 and 29.1%, respectively from Day 1 to Day 24. For LNG, the mean MRT 0-72 increased by 27.1%, while the mean Cl/F and Vd/F decreased by 62.4 and 86.3%, respectively from Day 1 to Day 24. The t 1/2 remained unchanged for LNG. The exposure of LNG significantly increased with repeated dosing, but that of EE just slightly increased.

Abstract
Objective: The clinical outcome, especial the immunologic responses to cancer and graft, of dendritic cell (DC) vaccine in the treatment of advanced de novo colorectal cancer (CRC) in renal transplant patients was investigated in this study. Materials and Methods: 7 patients were received 1 cycle tumor lysate pulsed autologous DC vaccine. The positive cell-mediated cytotoxicity responses to DC vaccine against CRC cell in two out of 7 patients were seen by delayed type hypersensitivity (DTH) test. The positive cell-mediated cytotoxicity responses to DC vaccine against normal kidney cell in all 7 patients were not seen by DTH tests and no notable change of renal function during and after vaccination. Conclusions: DC vaccine has emerged as a promising new strategy in the treatment of advanced de novo CRC in renal transplant patients and DC vaccines have become an attractive therapeutic option, developing immune responses specific against CRC cell, achieving clinical efficacy without graft failure.

Abstract
"Warburg effect" emphasizes that malignant cells exhibit active glycolysis even under aerobic conditions. Hexokinase 2 (HK2) is a key glycolytic enzyme that helps to exhibit a "Warburg effect". In the present study, the main aim was to detect the expression of HK2 in epithelial ovarian tumor tissues. Immunohistochemistry and qRT-PCR were used to examine the expression of HK2 in different epithelial ovarian tissues. The expression of HK2 in ovarian cancer tissues was significantly higher than that in normal ovarian, benign, and borderline tumors both in protein (p < 0.001) and mRNA (p < 0.05) levels. HK2 expression was significantly higher in Stage III/IV compared to Stage III (p < 0.001). Expression of HK2 in poorly-differentiated carcinoma was higher than that in well-differentiated carcinoma (p = 0.008). The level of HK2 was higher in serous groups than in non-serous groups in both protein (p = 0.008) and mRNA (p < 0.05) level. Collectively, HK2 is highly expressed in epithelial ovarian cancer, especially in serous groups. Its expression is related with clinical stage and histological differentiation.

Abstract
Methods for dealing with tied event times in the Cox proportional hazards model are well developed. Also, the partial likelihood provides a natural way to handle covariates that change over time. However, ties between event times and the times that discrete time-varying covariates change have not been systematically studied in the literature. In this article, we discuss the default behavior of current software and propose some simple methods for dealing with such ties. A simulation study shows that the default behavior of current software can lead to biased estimates of the coefficient of a binary time-varying covariate and that two proposed methods (Random Jitter and Equally Weighted) reduce estimation bias. The proposed methods can be easily implemented with existing software. The methods are illustrated on the well-known Stanford heart transplant data and data from a study on intimate partner violence and smoking.

Abstract
The recent ban on the use of antibiotics as a feed additive has led to the search for alternative sources of antibiotics in the feed industry. Presently, probiotics are considered as a potential substitute for antibiotic as a live biotherapeutic agent to improve animal health and performance. Accordingly, study was focused on evaluating the effect of Saccharomyces boulardii (Sb) and Bacillus subtilis B10 (Bs) on ultrastructure modulation and mucosal immunity development in broiler chickens. A total of three hundred 1-d-old Sanhuang broilers (a Chinese cross breed) were randomized into 3 groups, each group with 5 replications (n = 20). The control group (Ctr) was fed a basal diet containing an antibiotic (virginiamycin, 20 mg/kg). Meanwhile, broilers in experimental groups received Sb and Bs (1 × 10(8) cfu/kg of feed) in addition to the basal diet for 72 d. The results of the experimental groups revealed a significant improvement in live BW and relative weight of bursa of Fabricius and thymus. Also, intestinal villus height, width, and number of goblet cells increased in the Sb and Bs groups. Meanwhile, modulation in the intestinal ultrastructure and increased mRNA expression levels of occluding, cloudin2, and cloudin3 (P < 0.05) were observed in the Sb and Bs groups. Moreover, IgA-positive cells significantly increased in the jejunum of Sb- and Bs-supplemented groups (P < 0.05). Intestinal cytokines interleukin-6, tumor necrosis factor-α, interleukin-10, transforming growth factor-β, and secretory IgA concentrations were (P < 0.05) improved in the probiotic groups; however, Sb induced inflammatory and antiinflammatory cytokines (P < 0.05) in comparison with the Ctr group. The present findings conclusively revealed that Sb and Bs increased IgA-positive cells in the lumen of the intestinal villus and revealed that Sb and Bs could modulate intestinal ultrastructure through increasing occluding, cloudin2, and cloudin3 mRNA expression levels in broiler intestine.

Abstract
The complete genome sequence of the four RNAs of rice stripe virus Zhejiang isolate was determined. In addition to polymerase modules, the pc1 protein encoded on RNA1 harbours an ovarian tumour (OTU) - like cysteine protease signature near its N-terminus, suggesting that the protein might yield the viral polymerase and one or more additional proteins by autoproteolytic cleavage and/or have deubiquitination activity. A novel inverted repeat sequence motif was found to be universal within the intergenic regions of ambisense genome segments of tenuiviruses, supporting the possibility that it may be functionally important, perhaps in regulating transcription termination.

Abstract
Rice gall dwarf virus (RGDV) is a member of the genus Phytoreovirus within the family Reovirdae. Its genome has 12 segments of double-stranded RNA (dsRNA), of which the nucleotide sequences of segments S4, S6, and S7 were determined, providing the first complete genome sequence of RGDV. Each of the segments S4, S6, and S7 contained conserved terminal sequences conforming to the RGDV consensus, 5'-GGXA ... UGAU-3' (X = U or C). Each segment had a single predicted open reading frame encoding proteins with calculated molecular weights of 79.8, 58.6, and 53.3 kDa. These proteins appeared to be homologous to those encoded by the corresponding segments of rice dwarf virus and wound tumor virus, the other known members of the same genus, having about 20-30% amino acid identity to them. It is therefore likely that RGDV S4 and S6 encode non-structural proteins and S7 an inner core protein. Probable homologies between the segments of all known phytoreoviruses are summarized. Beyond these similarities, the RGDV proteins displayed no significant similarity to any other reported viral proteins.

Abstract
Human cervical carcinoma is one of the most common malignant tumors, but the mechanisms that orchestrate the multiple oncogenic insults required for initiation and progression are not clear. Notch signaling plays a critical role in maintaining the balance between cell proliferation, differentiation, and apoptosis, but perturbed Notch signaling may contribute to tumorigenesis. We now show that Notch1 is detected in all cervical cancer, including advanced diseases. We also constitutively overexpressed active Notch1 in human cervical carcinoma to explore the effects of Notch1 signaling on human cervical carcinoma cell growth and to investigate the underlying molecular mechanisms. The signaling may participate in the development of human cervical carcinoma cells, but overexpressed active Notch1 inhibits their growth through induction of cell cycle arrest. Increased Notch1 signaling induced a downmodulation of human papillomavirus transcription through suppression of activator protein (AP)-1 activity by upregulation of c-Jun and the decreased expression of c-Fos. Thus, Notch1 signaling plays a key role and exerts dual effects, functioning in context-specific manner.

Abstract
AIMS/HYPOTHESIS Increased expression and decreased degradation of extracellular matrix (ECM) proteins are key features of chronic diabetic complications. Fibronectin, a predominant ECM protein, has been shown to be overexpressed in all target organs of diabetic complications and in endothelial cells cultured in high levels of glucose. The present study was designed to elucidate the role of protein kinase B (Akt/PKB) in glucose-induced fibronectin mRNA expression and protein production in vascular endothelial cells. METHODS Human umbilical vein endothelial cells were cultured in the presence of high glucose to study Akt/PKB activation. The upstream and downstream mediators in the Akt/PKB pathway were also investigated using dominant negative transfections and specific inhibitors of signalling pathways. Cells were subjected to real time RT-PCR, western blotting, and confocal microscopy to assess Akt1/PKBalpha activation and fibronectin mRNA expression and protein production. To detect transcription factor activation, electrophoretic mobility shift assay was carried out. RESULTS Our data demonstrate that fibronectin mRNA expression and protein production that are induced by high glucose are mediated via activation of Akt/PKB, which is modulated by mitogen-activated protein kinase, phosphatidylinositol 3-kinase, and protein kinase C. Glucose-induced fibronectin mRNA expression and protein production are also mediated by Akt1/PKBalpha-dependent activation of the transcription factors nuclear factor-kappaB and activating protein-1. CONCLUSIONS/INTERPRETATION Our study provides insight into the mechanical basis of glucose-induced increases in fibronectin mRNA expression and protein production. High levels of glucose may increase fibronectin mRNA expression and protein production by activating Akt/PKB.

Abstract
The low-frequency torsional modes, index of refraction, and absorption of a tryptophan film and pressed powders from 0.2 to 2.0 THz (6.6-66 cm(-1)) were measured by terahertz time-domain spectroscopy at room temperature. It was found that there were two dominated torsional vibrational modes at around 1.435 and 1.842 THz. The associated relaxation lifetimes ( approximately 1 ps) for these modes of the tryptophan molecule were measured. Using a density-functional calculation, the origins of the observed torsional vibrations were assigned to the chain and ring of the tryptophan molecule.

Abstract
AIMS Dietary fatty acid profile, independent of caloric percent of fat, is a major regulator of body adiposity. This study examined the effects of dietary fat amount and types on fat storage and hypothalamic gene expression in the mouse model of chronic diet-induced obesity. METHODS The dietary interventions were in twofold: (1) the obesity was induced by a 13-week obesogenic fat diet compared with a low-fat (LF) diet, and (2) the reversibility was tested by using high n-3 polyunsaturated fat (PUFA) and LF diets. Fifty-four C57Bl/6 mice were fed a high-fat (59% in kcal) diet for 13 weeks and then classified as diet-induced obese (DIO) or diet-resistant (DR) mice according to upper and lower tertiles of body weight gain. The DIO mice were then subdivided into three groups for a 6-week secondary dietary intervention. Two of the groups were switched to either a high n-3 PUFA (DIO-n3) or a low-fat (10% in kcal, DIO-LF) diet, whereas the third (controls) and DR mice continued on the initial high-fat diet. Food efficiency was calculated as weekly body weight gain per gram of food intake. RESULTS After switching the DIO mice to the n-3 PUFA or LF diet, their body weights were reduced to the level of the DR and LF mice. The food efficiencies were, from the highest to lowest, in the order: DIO>LF>DR>DIO-LF>DIO-n3. Using quantitative in situ hybridization, we found that the DIO mice had higher levels of leptin receptor (LR, +290%, p<0.005) and neuropeptide Y (NPY, +25%, p<0.05) mRNA expression in the hypothalamic arcuate nucleus (Arc) than the DR mice, whereas the level of pro-opiomelanocortin (POMC) mRNA expression was significantly reduced (-45%, p<0.01). All effects that were essentially returned to DR levels by the change to the n-3 PUFA diet and, with the exception of a failure to normalize Arc NPY mRNA levels, by the change to LF diet. CONCLUSIONS Taken together, the present results show that both change in level and quality of dietary fat can potently alter hypothalamic neuropeptide expression and result in effective amelioration of diet-induced obesity. Interestingly, the n-3 PUFA diet when fed to already obese mice produced a pattern of hypothalamic gene expression similar to that in obesity resistant (DR) mice. It remains to be determined if the effects of n-3 fatty acids on brain neuropeptide gene expression are direct or indirect.

Abstract
AIMS/HYPOTHESIS To estimate the prevalence of diagnosed and undiagnosed diabetes and impaired fasting glucose in the general adult population of China. METHODS The International Collaborative Study of Cardiovascular Disease in ASIA, conducted from 2000 to 2001, included a nationally representative sample of 15 540 adults, aged 35 to 74 years. An overnight fasting blood specimen was collected to measure serum glucose and information on history of diabetes and use of hypoglycaemic medications was obtained by a standard questionnaire. Undiagnosed diabetes (fasting glucose > or =7.0 mmol/l) and impaired fasting glucose (6.1-6.9 mmol/l) were defined using the American Diabetes Association criteria. RESULTS Prevalence of self-reported diagnosed diabetes, undiagnosed diabetes, and impaired fasting glucose in Chinese adults were 1.3%, 4.2%, and 7.3%, respectively. Overall, 5.2% or 12.7 million men and 5.8% or 13.3 million women in China aged 35 to 74 years had diabetes (self-reported diagnosis plus undiagnosed diabetes). The age-standardized prevalence of diabetes was higher in residents of northern compared to southern China (7.4% vs 5.4%, p<0.001) and in those living in urban compared to rural areas (7.8% vs 5.1%, p<0.001). CONCLUSIONS/INTERPRETATION Our results show that the prevalence of diabetes in the adult population in China is much higher than previously reported. Three out of every four diabetes patients are undiagnosed, indicative of a lack of population-based screening programmmes and a relatively rapid and recent increase in incidence of diabetes. These results indicate that diabetes has become a major public health problem in China and underscore the need for national strategies aimed at prevention and treatment of diabetes.
