Objective To explore the syndrome of vital energy deficiency and blood stasis of CHF rat model. Methods The Wistar male rats were deligated the main stem of left coronary artery. The succeeded twenty rats were cut the diet half from the second week, and swam exhausted every day, compared with normal group. After four weeks, the general condition, heart function, heart construction and NE, PRA, AngⅡ,TXB2, PAI-1 were observed. Results General condition: Model group seemed tired, pelage dimed, tongue ecchymosis, meanwhile breath and heart rate raised. Heart function: There was significant difference between model group and normal group (P

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.

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.

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.
