Objective: To investigate the association between dietary pattern and cognitive performance in local residents aged ≥50 years in Shanghai. Methods: Data were obtained from the second round of Study of Global Ageing and Adult Health (SAGE) survey in Shanghai. Dietary patterns were surveyed by factor analysis. Cognitive tests were conducted to assess subjects' cognitive performance, including verbal recall, verbal fluency and digit test. Multiple linear regression analysis was used to evaluate the relationship between dietary patterns and cognition performance. Results: A total of 4 132 subjects with complete dietary and cognitive performance test data were included. Factor analysis was used to obtain three dietary patterns: including plant-based pattern, high animal-food pattern, high salt-oil pattern. After controlling for gender, age, education level and other factors, it was found that plant-based pattern (β=0.26,95%CI: 0.17-0.36) and high animal-food pattern (β=0.18, 95%CI:0.06-0.29) were positively associated with total cognitive test score while high salt-oil pattern (β=-0.28, 95%CI:-0.85--0.07) was negatively associated with verbal fluency test score. Conclusion: A dietary pattern with high intake of plant food and appropriate intake of animal food might be associated with better cognitive function of residents aged ≥50 years.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

The resolution and linear relationship of 12 components in quantitative analysis were good. The recovery rates were 99.2%-101.0% with RSD≤2.0%. The results of CA， PCA and OPLS-DA indicated that the differentiation of Aurantii Fructus in different production areas was great， and there were differences among different cultivars. ConclusionThe qualitative analysis of fingerprint and quantitative analysis of multiple indexes based on the same chromatographic analysis conditions are convenient， accurate and reliable， and combined with chemometrics， the identification and quality analysis of Aurantii Fructus from different production areas and origins can be realized， which can provide reference for quality control and evaluation of Aurantii Fructus.

BACKGROUND: Imprecise interpretation of coronary angiograms was reported and resulted in inappropriate revascularization. Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score is a comprehensive system to evaluate the complexity of the overall lesions. We hypothesized that a real-time SYNTAX score feedback from image analysts may rectify the mis-estimation and improve revascularization appropriateness in patients with stable coronary artery disease (CAD). METHODS: In this single-center, historical control study, patients with stable CAD with coronary lesion stenosis ≥50% were consecutively recruited. During the control period, SYNTAX scores were calculated by treating cardiologists. During the intervention period, SYNTAX scores were calculated by image analysts immediately after coronary angiography and were provided to cardiologists in real-time to aid decision-making. The primary outcome was revascularization deemed inappropriate by Chinese appropriate use criteria for coronary revascularization. RESULTS: A total of 3245 patients were enrolled and assigned to the control group (08/2016-03/2017, n = 1525) or the intervention group (03/2017-09/2017, n = 1720). For SYNTAX score tertiles, 17.9% patients were overestimated and 4.3% were underestimated by cardiologists in the control group. After adjustment, inappropriate revascularization significantly decreased in the intervention group compared with the control group (adjusted odds ratio [OR]: 0.83; 95% confidence interval [CI]: 0.73-0.95; P = 0.007). Both inappropriate percutaneous coronary intervention (adjusted OR: 0.82; 95% CI: 0.74-0.92; P < 0.001) and percutaneous coronary intervention utilization (adjusted OR: 0.88; 95% CI: 0.79-0.98; P = 0.016) decreased significantly in the intervention group. There was no significant difference in 1-year adverse cardiac events between the control group and the intervention group. CONCLUSIONS: Real-time SYNTAX score feedback significantly reduced inappropriate coronary revascularization in stable patients with CAD. CLINICAL TRIAL REGISTRATION Nos.

Objective:To study the serum pharmacochemistry of Aurantii Fructus （AF）， and to investigate the pharmacological material basis of AF extract in rats. Method:Rapid identification and speculation of the prototype constituents and their metabolites in vivo were carried out according to the relative retention time， accurate relative molecular mass， cleavage fragments of MS/MS and neutral loss of metabolites with ultrahigh performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry （UPLC-Q-TOF/MS） technique by comparing the differences between different samples such as AF extracts， blank plasma， and administered plasma under the same chromatographic and mass spectrometric conditions. Result:After oral administration of the AF extract， 74 transitional constituents absorbed into the blood were detected in serum， in which 49 compounds were prototype constituents and the other 25 were metabolites. The prototype constituents could be divided into dihydroflavones， polymethoxyflavonoids， limonins， coumarins and alkaloids. The identified metabolites included glucuronic acid conjugates， sulfuric acid conjugates， hydroxylated products of flavonoid glycosides and polymethoxyflavonoids， as well as the simultaneous glucuronidation and sulfation products. Conclusion:The constituents absorbed into the blood and their metabolites may be the pharmacodynamic components of AF. Among them， alkaloids， polymethoxyflavonoids and coumarins are mainly introduced into the blood in the prototype form， while naringin and neohesperidin （the index components） exert effect mainly through hydrolysis into aglycones. This work will help to further elucidate the material basis of AF.
