RESUMO
Objective To explore the association between dietary quality and perceived stress among adult Chinese. Methods The China Health and Nutrition Survey (CHNS) was used to investigate the association between dietary quality and perceived stress in Chinese adults. The Chinese Perceived Stress Scale (CPSS) was used to assess the perceived stress in Chinese adults. Binary logistic regression models were utilized to explore the relationship between diet quality and perceived stress. Restricted cubic splines (RCS) were utilized to clarify the dose response relationship between diet quality and perceived stress. Results Binary logistic regression models revealed that adults with CHEI score ranged from P25 to P50 and higher than P75 had 15.1% (OR=0.849，95%CI：0.738-0.977) and 23.0% (OR=0.770，95%CI：0.666-0.891) reduced risk of high perceived stress after multivariable adjustment when compared with adults with CHEI score less than P25. RCS results showed that the OR value of high perceived stress risk decreased gradually with increasing CHEI score in the overall population, but this association was not statistically significant in adults with lower CHEI score. Conclusion High dietary quality is associated with a reduced risk of high perceived stress. This study provides a theoretical reference for the health effects of high dietary quality on high perceived stress risk reduction.
RESUMO
Objective The study aims to find a suitable obesity index for predicting hyperuricemia (HUA)in Chinese adults. Methods The obesity indexes of 8133 subjects in China Health and Nutrition Survey in 2009 were calculated, and the basic situation of them was analyzed descriptively. χ2 test and t test were used to test the differences of categorical variables and continuous variables between the HUA group and the non-HUA group. The area under the curve (AUC) and receiver operating characteristic (ROC) curves were used to analyze the predictive value of these indices for HUA. Binary logistic regression was used to analyze the relationship between obesity and HUA. Results Demographic covariates, prevalence and Body Mass Index (BMI) all have impacts on the prevalence of HUA. Obesity indexes have a good predictive effect on HUA, and the Lipid Accumulation Product (LAP) is the best (AUC=0.77 (95% CI [0.75, 0.78]). Obesity indexes all have a significant correlation with HUA. When covariates were not adjusted, LAP had the highest OR value (OR=5.87, 95% CI [5.08, 6.77]). Conclusion LAP index is significantly related to HUA, and it can be used as an emerging index to assess the prevalence of HUA in Chinese adults.
RESUMO
Objective To evaluate the clinical characteristics and pregnant outcomes of gravidae with COVID-19. Methods This study involved nine gravidae with COVID-19 admitted to the Renmin Hospital of Wuhan University from January 22 to February 1, 2020. Their clinical data, including epidemiological history, clinical symptoms, laboratory examinations, chest CT, treatment, delivery mode, and pregnancy outcomes, were analyzed retrospectively. Specimens of maternal vaginal swab were collected in six pregnant women, and the specimens of amniotic fluid, cord blood, neonatal throat swab and breast milk samples were collected in four pregnant women who had a delivery during our study. All samples were tested for the existence of COVID-19. Descriptive analysis was applied in this study. Results (1) Among the nine cases, five were admitted in the third trimester and four in the second trimester. The median incubation period of COVID-19 was 8 (1-14) d. Fever was presented in all cases on admission, and the other commonly seen symptoms were cough (seven cases) and diarrhea (five cases). Other signs and symptoms were also reported, including shortness of breath, myalgia and fatigue (four cases in each), nasal obstruction, pharyngalgia, chest pain, and headache/dizziness (three cases in each), rash (two cases), and chills and expectoration (one case in each). The most common laboratory abnormalities were a decreased number of lymphocytes (seven cases) and elevated C-reactive protein (six cases). Chest CT scans were performed in seven women, and all showed patchy areas or ground-glass opacity in both lungs. Oligohydramnios was detected in only one case at 37 +5 weeks, which was 7 d after the diagnosis of COVID-19. (2) All nine cases received empiric antibiotic and antiviral therapy with Chinese medicine as adjuvant treatment. Eight patients required oxygen inhalation, and eight were treated with glucocorticoid. Six cases received immunotherapy. (3) Four of the nine cases had delivered, including three cesarean sections and one spontaneous vaginal preterm birth after premature rupture of membranes, and the mother was transferred to the intensive care unit 2 d after delivery due to acute respiratory distress syndrome. One case was terminated at 26 gestational weeks. Of the four neonates, there were two term and two premature babies, and one preterm baby was small-for-gestational-age. No neonatal asphyxia was observed. Serial real-time quantitative reverse transcription-polymerase chain reaction showed negative results in the detection of 2019-novel coronavirus in all samples obtained from amniotic fluid, umbilical cord blood, neonatal nasopharynx, breast milk, and vagina. Maternal conditions were all stable in all cases, including the four continuing pregnancy, and the terminated ones, except the case mentioned above. Conclusions There is no distinguishable clinical feature between pregnant and non-pregnant COVID-19 patients. So far, there is no evidence for vertical transmission or worsening perinatal outcome in mothers and babies.

RESUMO
The effect of ambient particulate matters on human health is of great concern. Numerous epidemiological studies have revealed that particulate matters were associated with increased population mortality. Moreover, many studies found that season and temperature might modify the effect of particles on mortality. This paper summarized the potential effect modification of season and temperature and the possible mechanism, so as to provide certain evidence and reference for the future relevant studies.

<p><b>OBJECTIVE</b>To evaluate the acute effects of indoor and outdoor particulate matter on lung function and respiratory symptoms of college students in winter.</p><p><b>METHODS</b>A panel of 37 college students aged 19-21 in Wuhan were included and the investigation was carried out from 12/23/2009 to 01/05/2010. Daily morning/evening forced expiratory volume in one second (FEV1) and respiratory symptoms (cough, phlegm and runny) were measured and reported by subjects, respectively. Meanwhile, daily data of indoors and outdoors PM10, PM2.5, temperature, and relative humidity were collected. Generalized Estimating Equations (GEEs) were used to estimate the association between particulate matters exposure and respiratory symptoms and FEV1).</p><p><b>RESULTS</b>Average daily concentrations of indoor, outdoor PM2.5 during the study period were (110.6 ± 42.3), (143.5 ± 51.2) µg/m³, (148.2 ± 43.2) and (239.1 ± 71.3) µg/m³ for indoor, outdoor PM10, respectively. Outdoor exposure to PM2.5 on lag 0 had little effect on evening FEV1). However, researchers observed a significant lagging effect (lag 1 d) and accumulative effect (lag 0-1 d and lag 0-2 d). A rise in the PM2.5 concentration of 10 µg/m³ resulted in the change of evening FEV1) of -0.28% (95% CI: -0.52%, -0.03%), -0.45% (95% CI: -0.81%, -0.08%) and -0.63% (95% CI: -1.15%, -0.11%), respectively. For respiratory symptoms of coughing up phlegm, 10 mg/m³ increase of indoor/outdoor PM2.5 concentration were associated with odds ratio of 1.18 (95% CI: 1.02-1.36) and 1.08 (95% CI: 0.97-1.19), respectively. Moreover, risk of coughing up phlegm increased with lagging time, and accumulative time of indoor and outdoor PM2.5 and PM10.</p><p><b>CONCLUSION</b>Our study suggested that short-term exposure to particulate matters in winter was significantly associated with acute changes of respiratory symptoms and FEV1) of college students in Wuhan. Moreover, the effects of particulate matters tended to be larger as the increase of lagged and accumulative days.</p>

<p><b>OBJECTIVE</b>To investigate the effects of pyrethroids on the concentrations of thyroid hormone in rat brain.</p><p><b>METHOD</b>Permethrin (PM) and deltamethrin (DM) were administered to the rats with daily doses of 100, 200 and 400 mg.kg-1.d-1 and 6.25, 12.5 and 25 mg.kg-1.d-1, respectivelly for 15 days. Serum and brain tissue determinations of thyroxin (T4) and triiodothyronine (T3) were performed by radioimmunoassay (RIA).</p><p><b>RESULTS</b>PM induced a dose dependent decrease in the serum levels of T4, T3, fT4 and fT3 and an increase in the serum TSH levels, whereas DM was only able to induce a dose dependent decrease in the serum levels of T4. PM treatment reduced both the levels of T4 and T3 in homogenates of the cerebral cortex and hippocampus respectively, whereas the highest dose of DM decreased only the cerebral cortex levels of T4. The effects of subchronic treatment with PM and DM on the concentrations of T3 were further investigated in the subcellular fractions, namely nuclei, mitochondria, myelin and synaptosomes of the cerebral cortex and hippocampus. PM treatment induced a decrease in the nuclear and synaptosomal concentrations of T3 of either the cerebral cortex or hippocampus, whereas DM reduced the levels of T3 especially in the mitochondria of the cortex and hippocampus.</p><p><b>CONCLUSIONS</b>Treatment with pyrethroids subchronically to the rats would affect the serum and brain tissue levels of T4 and T3. These results indicate that the pyrethroids-induced neurotoxicity may involve at least in part an impairment of the physiological action of T3 at its subcellular targets.</p>
