The morphological abnormalities in myelin sheath of sciatic nerves were observed through electron microscope after HD-exposure. The S100β contents in 100 mg/kg and 300 mg/kg groups remained relatively unaffected with 92% and 79% of the control respectively after HD-intoxication, and a increase to 149%(P less then 0. 05) and 119% after a recovery of 8 weeks was accompanied with. As to S100β mRNA, HD-intoxication was associated with decreased expression to 0. 65(P less then 0. 05) and 0. 56 times(P less then 0. 05) of the control, and 1. 46 and 0. 87 times for 8-week recovery individually. CONCLUSION The S100β protein and mRNA levels were influenced by HD exposure, and the result suggested that S100β might be involved in HD-induced peripheral axonopathy.OBJECTIVE To explore subacute toxic effects of benzo[a]pyrene on the cardiovascular system of male Wistar rats. METHODS Forty SPF grade male Wistar rats were randomly divided into blank control group, solvent control group, low, medium and high dose group(B[a]P concentrations were 1. 0, 2. 5 and 6. 25 mg/kg, respectively), eight in each group. The solvent group was given the same amount of olive oil and the blank group was not treated at all for 28 consecutive days. After the end of the exposure, the left ventricular structural function and hemodynamic changes were observed with Prospect 3. 0 small animal ultrasound imager and BL-410 biological function test system. Pathological changes of rat thoracic aorta and left ventricle were observed by HE staining. RESULTS The total difference in ejection fraction(EF), fractional shortening(FS) and left ventricular end diastolic pressure(LVEDP) between the groups was statistically significant(H=11. 497, P=0. 022; H=11. 422, P=0. 022; H=10. 104, P=0. 039). The EF and FS of the middle dose group were lower than the solvent group(adjusted P less then 0. 05), the LVEDP of the high dose group was higher than that of the solvent group(adjusted P less then 0. 05). Pifithrinα The HE staining of thoracic aorta in the medium and high dose groups showed the loss of endothelial cells, the shedding of some endothelial cells, the exposure of subintimal collagen, the large gap of the middle layer. In the medium and high dose group, left ventricular transverse striations were blurred, muscle fibers reduced or disappeared, the myocardial space widened, inflammatory cells or the myocardial interspace bleeding phenomenon was occasionally observed. CONCLUSION Benzo[a]pyrene can cause cardiovascular and endothelial damage in male Wistar rats.OBJECTIVE To prospectively analyze the effects of gestational stress around 3 months of conception and stress in the second and third trimesters of pregnancy on the dietary preferences in late pregnancy of women in Shanghai City. METHODS From April 2016 to April 2018, pregnant women who registered in 2 delivery hospitals in Shanghai were recruited as participants of Shanghai Maternal-Child Pair Cohort with informed consent. Life Events Scale for Pregnant Women was used to evaluate the gestational stress around 3 months of conception and stress during 32-36 weeks of pregnancy, respectively. Food Frequency Questionnaire and factor analysis were used to evaluate the dietary tendency in late pregnancy. Binary Logistic regression model was used to analyze the relationship between gestational stress and dietary tendency. RESULTS Among the 2634 pregnant women included in this study, factor analysis revealed six dietary preferences in the third trimester of pregnancy, which were 'balanced', 'meat and be of diet in late pregnancy. Compared with that in the second and third trimesters of pregnancy, gestational stress around conception is more likely to negatively affect dietary preferences in late pregnancy.Healthcare workers (HCW) are potentially at increased risk of infection with coronavirus disease (COVID-19) and may transmit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to vulnerable patients. We present results from staff testing at Sheffield Teaching Hospitals NHS Foundation Trust, United Kingdom. Between 16 and 29 March 2020, 1,533 symptomatic HCW were tested, of whom 282 (18%) were positive for SARS-CoV-2. Testing HCW is a crucial strategy to optimise staffing levels during this outbreak.The World Health Organization has declared COVID-19 caused by the newly discovered SARS-CoV-2 a pandemic. Due to growing demand for reagents and/or kits to extract SARS-CoV-2 RNA for subsequent RT-qPCR diagnostics, there is a worldwide risk of shortages. With a detection sensitivity of 97.4% (95% CI 86.2-99.9%), we describe a simple, fast, alternative workflow for molecular detection of SARS-CoV-2, where samples are simply heat-processed for 5 min at 98 °C before a commonly-used RT-qPCR procedure.Several French regions where coronavirus disease (COVID-19) has been reported currently show a renewed increase in ILI cases in the general practice-based Sentinelles network. We computed the number of excess cases by region from 24 February to 8 March 2020 and found a correlation with the number of reported COVID-19 cases so far. The data suggest larger circulation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the French population than apparent from confirmed cases.IntroductionLymphogranuloma venereum (LGV), an invasive form of Chlamydia trachomatis infection, has been reported among (mainly HIV-positive) men who have sex with men (MSM) since 2003. In the Netherlands, LGV testing recommendations changed from selective to universal testing in 2015. Changes in tested populations could have led to incomparable LGV positivity rates over time.AimWe investigated LGV trends among MSM attending Centres for Sexual Health using surveillance data between 2011 and 2017.MethodsLGV positivity was calculated among MSM tested for rectal Chlamydia infection and MSM tested specifically for LGV. With multivariable logistic regression analysis, the association between years and LGV was adjusted for testing indicators and determinants.ResultsWe included 224,194 consultations. LGV increased from 86 in 2011 to 270 in 2017. Among LGV-positives, proportions of HIV-negative and asymptomatic MSM increased from 17.4% to 45.6% and from 31.4% to 49.3%, respectively, between 2011 and 2017. Among MSM tested for rectal chlamydia, LGV positivity increased from 0.
