Abstract
Quantum dots (QDs) are a new class of fluorescent labelling for biological and biomedical applications. In this study, the authors evaluated the sensitivity and stability of quantum-dots-based immunolabelling, in comparison with the conventional fluorescein-isothiocyanate-based immunolabelling (FITC), for detecting prostate-specific antigen (PSA) expression in human prostate cancer. The authors' data revealed that the two methods had similar sensitivity in differential display of the PSA expression correlated with tumour stage and grade (=0.88, p<0.001). Moreover, the intensity of QDs fluorescence remain stable for 10 days after conjugation to the PSA protein in 97% of the cases and more than 1 month in 92% of the cases, although the FITC fluorescence became undetectable after 6 min for all cases.

Abstract
BACKGROUND Early Intervention in Psychosis Services (EIS) for young people in England experiencing first-episode psychosis (FEP) were commissioned in 2002, based on an expected incidence of 15 cases per 100 000 person-years, as reported by schizophrenia epidemiology in highly urban settings. Unconfirmed reports from EIS thereafter have suggested higher than anticipated rates. The aim of this study was to compare the observed with the expected incidence and delineate the clinical epidemiology of FEP using epidemiologically complete data from the CAMEO EIS, over a 6-year period in Cambridgeshire, for a mixed rural-urban population. METHOD A population-based study of FEP (ICD-10, F10-39) in people aged 17-35 years referred between 2002 and 2007; the denominator was estimated from mid-year census statistics. Sociodemographic variation was explored by Poisson regression. Crude and directly standardized rates (for age, sex and ethnicity) were compared with pre-EIS rates from two major epidemiological FEP studies conducted in urban English settings. RESULTS A total of 285 cases met FEP diagnoses in CAMEO, yielding a crude incidence of 50 per 100 000 person-years [95% confidence interval (CI) 44.5-56.2]. Age- and sex-adjusted rates were raised for people from black ethnic groups compared with the white British [incidence rate ratio (IRR) 2.1, 95% CI 1.1-3.8]. Rates in our EIS were comparable with pre-EIS rates observed in more urban areas after age, sex and ethnicity standardization. CONCLUSIONS Our findings suggest that the incidence observed in EIS is far higher than originally anticipated and is comparable to rates observed in more urban settings prior to the advent of EIS. Sociodemographic variation due to ethnicity and other factors extend beyond urban populations. Our results have implications for psychosis aetiology and service planning.

Abstract
INTRODUCTION Due to the organ supply shortage, the donor pool has been expanded to include non-heart-beating donors, where renal warm ischemia/reperfusion (I/R) injury is inevitable. This study was undertaken to determine whether Yisheng injection (YM) could attenuate renal warm I/R injury in mice. MATERIALS AND METHODS Male C57BL/6 mice were divided into sham, ischemic, and YM-treated groups using 50 minutes of left kidney ischemia. Mice were humanely killed at 4 or 24 hours postreperfusion. We assayed the effects of YM on liver functional injury, neutrophil recruitment, and proinflammatory mediators after renal I/R injury. RESULTS Renal I/R produced dramatic injuries in mouse kidneys. Administration of YM reduced liver function (urea nitrogen of untreated vs treated, 4.7 +/- 0.6 vs 26.6 +/- 1.5 mmol/L; P < .01) and histological injury (histological scores of untreated vs treated, 4.12 +/- 0.14 vs 0.98 +/- 0.07; P < .01). YM at doses of 5, 15, or 25 mg/kg reduced the serum levels of tumor necrosis factor-alpha (TNF-alpha) by about 32.9%, 55.1%, and 74.5%, respectively. Moreover, YM also suppressed the increase in messenger RNA (mRNA) and protein expressions of TNF-alpha and intercellular adhesion molecule-1 (ICAM-1), as well as abrogated neutrophil recruitment in a dose-dependent manner. CONCLUSION YM protects murine kidneys from warm I/R injury, probably via decreasing functional injury, reducing neutrophil infiltration, and suppressing the overexpression of proinflammatory mediators and adhesion molecules.

Abstract
Shuanghuanglian (SHL), an extract mixture isolated from three medicinal herbs, has been used in China as an injection in traditional Chinese medicine to treat viral or bacterial infection. This study examined the hypotensive response in rats induced by SHL and its possible mechanisms. Mean arterial pressure (MAP) and electrocardiograms (ECGs) were studied after intravenous injection of histamine and SHL. Diphenhydramine, an H1 receptor antagonist, the compound 48/80, a promoter of histamine release, and cromolyn, a histamine release inhibitor, were also used to investigate the potential mechanisms of that response. In addition, the histamine level in plasma was measured after administration of SHL and compound 48/80. Both SHL and histamine led to a MAP reduction immediately but did not affect ECGs when initially administered in a similar manner, though this reduction was partially attenuated by diphenhydramine. Pretreatment blocked the rats' reaction to compound 48/80 but not to SHL. The plasma histamine level in rats was also elevated by SHL. SHL can induce severe hypotension through histamine release upon initial administration. In combination with the direct effects of its histaminelike substances on target tissue, SHL likely has the potential to cause an anaphylactoid reaction.

Abstract
The rabbit has been widely used for the study of human atherosclerosis; however, the method for analysis of the atherosclerotic lesions has not been standardized between laboratories. The present study reports a practical method for quantifying the changes that occur in aortic atherosclerosis of rabbits. Male Japanese white rabbits were fed with either a standard chow or a diet containing 10% fat and 0.3% cholesterol for 16 weeks. Plasma concentrations of glucose, insulin, total cholesterol, triglycerides and high-density lipoprotein were measured. Aortic atherosclerotic lesions were assessed in quantitative fashion using an image analysis system that measured (1) the gross area of the entire aorta affected by atherosclerosis as defined by Sudan IV staining, (2) the microscopical intimal lesion defined by the elastic van Gieson stain and (3) the infiltration of macrophages and smooth muscle cell proliferation as determined immunohistochemically. The rabbits developed severe aortic atherosclerosis without apparent abnormality of glucose metabolism. The quantitative method described here will be useful for the further investigation of atherosclerosis in rabbits.

Abstract
Twelve women with obstetric cholestasis were given dexamethasone after failure to respond to ursodeoxycholic acid. Clinical improvement was achieved in eight cases, without complete resolution of symptoms. Biochemical response was achieved in seven cases. All but two cases had good correlation between clinical and biochemical response. Women of Asian and South American origin were more likely to respond to dexamethasone than Caucasians. There were no reported maternal or fetal side-effects. However, the subsequent consequences of dexamethasone treatment for the mother and fetus have not been thoroughly evaluated. Therefore, even in Asian and South American women, larger studies of dexamethasone are required before this treatment can be recommended as a universally safe and effective treatment for obstetric cholestasis.

Abstract
BACKGROUND Clients of female sex workers (CFSWs) are at risk for HIV transmission; relevant surveillance and interventions for this vulnerable group are scarce. The China-UK HIV/AIDS Prevention and Care Project launched an enhanced intervention programme involving peer education, seminars, testing services and social gatherings and so forth, and two behavioural surveillance studies (BSS) targeting CFSWs in Suining, Sichuan. METHODS Two cross-sectional BSS (a baseline survey and an evaluative survey) were conducted in September 2005 and May 2006, respectively. In total, 356 and 372 respondents who patronised some low-end sex services were interviewed by peer interviewers. Another triangulation condom audit exercise was conducted in June 2006. RESULTS Prevalence of respondents using at least one prevention service increased from 50.3% in 2005 to 68.5% in 2006 (AOR = 2.2). Respondents of the evaluative survey compared with their counterparts of the baseline survey had lower prevalence of inconsistent condom users in the last 6 months (44.1% vs 77.0%; AOR = 0.2) and higher prevalence of condom use in the last episode of commercial sex (78.0% vs 41.5%; AOR = 4.9). The triangulation audit showed that condoms were used by 73.8% of CFSWs. The multivariate analysis shows that year of study (OR = 0.3), self-reported sexually transmitted disease symptoms (OR = 2.9), use of face-to-face counselling services (OR = 0.5) and so forth were significantly associated with inconsistent condom use during commercial sex in the last 6 months. CONCLUSIONS Condom use and service use behaviours changed in the study population over a time period when an enhanced intervention programme was implemented. Such effective programmes may be applied to other locations in China.

Abstract
SUMMARY Syphilis testing guidelines in China are usually based on symptomatic criteria, overlooking risk assessment and ultimately opportunities for disease detection and control. We used data from 10,695 sexually transmitted disease (STD) clinic patients in Guangxi, China, to assess the efficacy of a potential screening tool inquiring about behavioural and health risk factors in identifying the STD patients who should not be triaged for syphilis testing under current guidelines, but on the contrary receive such testing. Validity testing of the screening tool was performed and receiver-operating characteristic curves were plotted to determine an optimal total risk score cut-off for testing. About 40.9% of patients with positive toluidine red unheated serum test and Treponema pallidum particle agglutination test did not show hallmark signs of syphilis. The screening tool was more sensitive in detecting infection in non-triaged male versus female patients (highest sensitivity = 90% vs. 55%) and the cut-off score to warrant testing was lower in non-triaged female patients than in non-triaged male patients (cut-off = 1 vs. 2). Most of the cases were missed among female STD patients. In spite of selective testing based on behavioural and health indicators that improve case detection, cases were still missed. Our study supports universal testing for syphilis in the STD population.

Abstract
OBJECTIVE Hepatic ischemia/reperfusion injury (IRI) may cause acute inflammatory damage, producing significant organ dysfunction, an important problem for liver transplantation. Previous studies have demonstrated that Tetrandrine (Tet), a component of traditional Chinese herbal medicine, shows protective effects to scavenge active oxygen radicals and inhibit lipid peroxidation. In this study, we examined whether Tet has a protective effect on mouse hepatic IRI. MATERIALS AND METHODS Male C57BL/6 mice were divided into sham, ischemic, and Tet-treated groups; 90 minutes of warm ischemia was performed on the left liver lobe. Tet (20 mg/kg) was injected intraperitoneally at 1 hour before ischemia with a second intravenous dose was injected just before reperfusion. Blood and liver samples were collected at 6 hours after reperfusion. We analyzed the hepatocellular injury, oxidative stress, neutrophil recruitment, and tumor necrosis factor-alpha (TNF-alpha) generation associated with hepatic IRI. RESULTS Undergoing 90 minutes of ischemia and 6 hours reperfusion caused dramatic injuries in mouse livers. Administration of Tet (20 mg/kg) reduced serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH); decreased liver edema, TNF-alpha, myeloperoxidase (MPO) and malondialdehyde (MDA) contents; and ameliorated the down-regulation of superoxide dismutase (SOD) activity. CONCLUSION Tet showed protective effects on mouse hepatic IRI.

Abstract
BACKGROUND Abnormalities in reinforcement learning and reversal learning have been reported in psychosis, possibly secondary to subcortical dopamine abnormalities. METHODS We studied simple discrimination (SD) learning and reversal learning in a sample of 119 first-episode psychosis patients from the Cambridge early psychosis service (CAMEO) and 107 control participants. We used data on reinforcement learning and reversal learning extracted from the Cambridge Neuropsychological Test Automated Battery Intradimensional-Extradimensional shift task, which measures cognitive flexibility but also involves simple reinforcement learning (SD learning) and reversal learning stages. We also gathered diagnostic information to examine whether there were any differences between patients ultimately diagnosed with schizophrenia-spectrum disorders and those diagnosed with affective psychosis. RESULTS Psychosis patients demonstrated deficits in simple reinforcement learning (SD learning) and in reversal learning, with no differences between affective psychosis and schizophrenia-spectrum psychosis. There was a significant modest correlation between reversal errors and negative symptoms (Spearman rho = 0.3, P = .02). CONCLUSIONS There are reinforcement learning abnormalities in first-episode psychosis, which correlate with negative symptoms, suggesting a possible role for orbitofrontal cortex and ventral striatal pathology in the pathogenesis of motivational deficits in psychosis.
