To observe the incidence of syncope in patients with acute and critical cardiovascular diseases and to explore the risk factors of death.

925 cases of acute heart failure, acute myocardial infarction, pulmonary embolism, arrhythmia and aortic dissection rupture who participated in Prospective, Multi-Center Registered Research Project for Chinese Syncope Patients from March 2018 to March 2020, admitted to the department of emergency of Nanyang Second General Hospital were selected as the research objects. The incidence and mortality of syncope were recorded, and the patients were divided into syncope group and non-syncope group according to whether they were accompanied by syncope or not. The incidence of syncope in male and female patients with different cardiovascular critical diseases, the age and mortality of cardiovascular critical patients with syncope or not were analyzed and compared. Multivariate Logistic regression analysis was used to analyze the risk factors of death, and receiver operating chacal cardiovascular diseases. ROC curve analysis showed that syncope had a certain predictive value for 28-day prognosis of patients [the area under the ROC curve (AUC) = 0.760, P = 0.000], when the cut-off value was 4.12, the sensitivity was 88.51%, the specificity was 78.05%, the positive predictive value was 81.31%, and the negative predictive value was 84.27%.

Syncope is an independent risk factor of death in patients with acute and critical cardiovascular diseases. For patients with syncope as the chief complaint, we should quickly identify the types of acute and critical diseases and assess the risk of sudden death.

To assess the age-related differences in the management strategies and outcomes of patients with acute coronary syndrome (ACS) under the chest pain center model.

Clinical data of 2 833 patients with ACS were enrolled in the retrospective observational registry between January 2017 and June 2019 at 11 hospitals with chest pain centers in Chengdu. The patients were divided into four groups according to their ages < 55 years old group (n = 569), 55-64 years old group (n = 556), 65-74 years old group (n = 804), ≥ 75 years old group (n = 904). The collected data included the patients' demographic characteristics, cardiovascular risk factors, medical history, symptoms and signs of onset, experimental examination, types of ACS and the time from the symptom to the hospital (S-to-D), etc., and the clinical characteristics, management strategies, all-cause mortality in the hospital, and the incidence of major adverse cardiovascular and cerebrovascular events (MACCE) within 1 year after discharge were compared. T1.387 (1.003-1.916), 1.314 (1.155-1.495), 0.547 (0.402-0.745), all P < 0.05].

In the chest pain center model, compared with other age of ACS patients, the proportion of NSTEMI in elderly patients group aged ≥ 75 years old was higher, the proportion of PCI was lower, and the clinical outcome was worse. However, the prognosis of elderly patients receiving PCI treatment was better than the patients receiving conservative treatment.

To systematically evaluate the predictive value of neutrophil-lymphocyte ratio (NLR) in acute kidney injury (AKI).

All studies about the predictive effect of NLR on AKI were searched in the National Medical Library of the United States PubMed Database, the Embase database in the Netherlands, the Chinese Biology Medicine disc (CBMdisc) and the Chinese Evidence Based Medicine Cochrane Centre Database (CEBM/CCD). The data updated by October 2020, and regardless of language, region or whether blind method was used. Tacrine mouse Two authors independently extracted data and evaluated the quality of the studies. Data extracted from the studies were analyzed with RevMan 5.3 to assess the predictive value of NLR on AKI. A subgroup Meta-analysis was conducted to assess the predictive value of NLR on AKI according to different countries, different disease types (cardiovascular surgery, infectious diseases, other diseases including burns, cirrhosis, and emergency), and different sample sizes (≤ 300 cases and > 300 cases). The e of AKI in studies with a sample size of ≤ 300 cases (MD = 6.02, 95%CI was 4.90-7.14, P < 0.000 01) and > 300 cases (MD = 1.32, 95%CI was 0.61-2.03, P = 0.000 3). There was no significant publication bias in the included studies assessed by funnel plots.

NLR is an important predictive tool for AKI.

To observe the effect of fluid therapy on volume and coagulation function in patients with severe postpartum hemorrhage during cesarean section of placenta accreta under the guidance of inferior vena cava diameter (IVCD) and inferior vena cava collapse index (IVC-CI).

A prospective randomized controlled study was conducted in 60 pregnant women with severe postpartum hemorrhage (blood loss ≥ 1 000 mL) who were hospitalized for delivery or referred for delivery in the Peking University Third Hospital from December 2018 to July 2019. The patients were divided into routine fluid replacement group and goal-oriented fluid resuscitation group (goal-oriented fluid replacement therapy was given) according to the different ways of fluid replacement. The hemodynamics, blood gas analysis, coagulation function, total fluid replacement, urine volume, prognosis, intraoperative vasoactive drugs utilization rate and postoperative adverse events were recorded before skin incision, after the fetus delivered, postpartum hemorrhage and at the end of operation, and the differences of these indices between the two groups were compared.
