OBJECTIVETo analyze the incidence of coronary artery disease (CAD) and outcome of patients with left ventricular noncompaction (LVNC).

METHODSFifty-one patients with LVNC evaluated by echocardiography and/or cardiac magnetic resonance (CMR) from January 2006 to August 2010 were retrospectively reviewed. Coronary angiography or MDCT was performed for detecting coronary artery disease. Predictors of the cardiac events were analyzed by Cox regression analysis.

RESULTSThere were 31 LVNC patients without CAD and 20 LVNC patients with CAD including single vessel coronary disease in 9 cases, double vessel coronary disease in 3 cases, three vessel coronary disease in 5 cases and left main coronary disease in 3 cases. Coronary artery bypass graft and percutaneous coronary intervention (PCI) were performed in 4 patients. Compared to LVNC patients without CAD, mean age (P = 0.008), incidence of hypertension (65.0% vs. 19.4%, P = 0.001), diabetes mellitus (40.0% vs. 12.9%, P = 0.026) and hyperlipidemia (55.0% vs. 25.8%, P = 0.035) were significantly higher while NT-proBNP level was significantly lower (P = 0.049) in LVNC patients with CAD. Incidence of major cardiac events was similar in LVNC patients with or without CAD. LogNT-proBNP is the independent prognostic factor for adverse cardiac events in patients with LVNC (HR 3.993, 95%CI 1.140 - 13.988, P = 0.030).

CONCLUSIONSCoronary artery disease is common in patients with LVNC and associated with traditional risk factors for CAD. Poor prognosis is associated with increased NT-proBNP but not with CAD in this patient cohort.

OBJECTIVETo investigate the dynamic trend of specific antibody against severe acute respiratory syndrome (SARS)-CoV in serum collected at various periods among employees in Guangzhou Xinyuan animal market.

METHODSVolunteers from employees of the animal market were recruited and their serum specific antibody against SARS-CoV were determined by enzyme linked immunesorbent assay (ELISA) method.

RESULTSPositive SARS-CoV specific IgG antibody was found 25.61% (n = 328), 13.03% (n = 238), 12.59% (n = 135), 5.04% (n = 139) and 9.43% (n = 53) among volunteers, which were sampled in May 2003, Dec. 2003, Jan. 2004, July 2004 and June 2005 respectively. No specific IgM antibody was found in all of those samples. Among 129 samples which were tested twice or more, 97 were all negative, 18 all positive, 13 changed from positive to negative but only one sample from negative to positive. When the volunteers were divided by the duration of their working experiences as short-term or long-term, those who had worked at animal market for less than or more then 6 months when being tested, the positive rate for long-term employees were relatively constant, however, all of the persons employed after January 2004, when the palm civets and raccoon dogs were culled from the market, were tested negative.

CONCLUSIONThe prevalence of specific antibody against SARS-CoV in employees of the animal market were somehow related with the presence or absence of palm civet. No serum was tested positive for persons who were employed after palm civets and raccoon dogs were culled from market. This data indicated that the SARS-CoV might have been from the palm civets and raccoon dog, and the animal market seemed to serve as one of the sources of infection.

OBJECTIVES: To study the survival rate and the incidence of complications of very preterm infants and the factors influencing the survival rate and the incidence of complications. METHODS: The medical data of the very preterm infants with a gestational age of <32 weeks and who were admitted to the Department of Neonatology in 11 hospitals of Jiangsu Province in China from January 2018 to December 2019 were retrospectively reviewed. Their survival rate and the incidence of serious complications were analyzed. A multivariate logistic regression analysis was used to evaluate the risk factors for death and serious complications in very preterm infants. RESULTS: A total of 2 339 very preterm infants were enrolled, among whom 2 010 (85.93%) survived and 1 507 (64.43%) survived without serious complications. The groups with a gestational age of 22-25 CONCLUSIONS The survival rate is closely associated with gestational age in very preterm infants. A low 1-minute Apgar score (≤3) may increase the risk of death in very preterm infants, while high gestational age, high birth weight, and prenatal use of glucocorticoids are associated with the reduced risk of death. A low 5-minute Apgar score (≤3) and maternal chorioamnionitis may increase the risk of serious complications in these infants, while high gestational age and high birth weight may reduce the risk of serious complications.

OBJECTIVE: To evaluate the clinical features of preterm infants with a birth weight less than 1 500 g undergoing different intensities of resuscitation. METHODS: A retrospective analysis was performed for the preterm infants with a birth weight less than 1 500 g and a gestational age less than 32 weeks who were treated in the neonatal intensive care unit of 20 hospitals in Jiangsu, China from January 2018 to December 2019. According to the intensity of resuscitation in the delivery room, the infants were divided into three groups:non-tracheal intubation ( RESULTS: Compared with the non-tracheal intubation group, the tracheal intubation and ECPR groups had significantly lower rates of cesarean section and use of antenatal corticosteroid ( CONCLUSIONS For preterm infants with a birth weight less than 1 500 g, the higher intensity of resuscitation in the delivery room is related to lower rate of antenatal corticosteroid therapy, lower gestational age, and lower birth weight. The infants undergoing tracheal intubation or ECRP in the delivery room have an increased incidence rate of adverse clinical outcomes. This suggests that it is important to improve the quality of perinatal management and delivery room resuscitation to improve the prognosis of the infants.
