Effect of the timing of peripancreatic fluid drainage on prognosis in patients with severe acute pancreatitis: a two-center clinical retrospective study / 中华急诊医学杂志

Objective:To evaluate the effect of the timing of peripancreatic drainage on the survival outcome of patients with severe acute pancreatitis (SAP).Methods:This retrospective study included 271 patients with SAP admitted to two tertiary hospitals from January 2015 to December 2019. The Acute Physiology and Chronic Health EvaluationⅡ score (APACHEⅡ), Sequential Organ Failure Assessment score (SOFA), computed tomography (CT) grade, peripancreatic drainage situations, and survival outcome of patients were recorded. Patients were divided into the early and non-early peripancreatic catheter drainage groups (EPCD and non-EPCD). The data were analyzed using the Cox proportional hazard model for propensity score matching (PSM) and stratification.Results:After PSM, the 30-day and 90-day risk of death between the EPCD and non-EPCD groups were significantly different (0.134, 95% CI: 0.029-0.576, P=0.007; 0.166, 95% CI: 0.044-0.631, P=0.008, respectively). Furthermore, stratified analysis revealed significant differences in 30-day and 90-day risk of death between the EPCD and non-EPCD groups when the SOFA score was≥4 or the APACHEⅡ score was ≥8. Conclusions:For patients with SAP with SOFA score ≥4 or APACHEⅡ score≥8, early peripancreatic drainage can reduce the risk of death, but CT grading is not helpful for the decision-making of drainage timing in patients with SAP.

Development and evaluation of a predictive nomogram for survival in heat stroke patients: a retrospective cohort study / 世界急诊医学杂志（英文）

@#BACKGROUND: This study aimed to establish an effective nomogram to predict the survival of heat stroke (HS) based on risk factors. METHODS: This was a retrospective, observational multicenter cohort study. We analyzed patients diagnosed with HS, who were treated between May 1 and September 30, 2018 at 15 tertiary hospitals from 11 cities in Northern China. RESULTS: Among the 175 patients, 32 patients (18.29%) died before hospital discharge. After the univariate analysis, mechanical ventilation, initial mean arterial pressure <70 mmHg, maximum heart rate, lab results on day 1 (white blood cell count, alanine aminotransferase, creatinine), and Glasgow admission prediction score were included in multivariate analysis. Multivariate Cox regression showed that invasive ventilation, initial mean arterial pressure <70 mmHg (1 mmHg=0.133 kPa), and Glasgow admission prediction score were independent risk factors for HS. The nomogram was established for predicting 7-d and 14-d survival in the training cohort. The nomogram exhibited a concordance index (C-index) of 0.880 (95% confidence interval [95% CI] 0.831-0.930) by bootstrapping validation (B=1,000). Furthermore, the nomogram performed better when predicting 14-d survival, compared to 7-d survival. The prognostic index cut-off value was set at 2.085, according to the operating characteristic curve for overall survival prediction. The model showed good calibration ability in the internal and external validation datasets. CONCLUSION: A novel nomogram, integrated with prognostic factors, was proposed; it was highly predictive of the survival in HS patients.

Objective@#This study aims to investigate the epidemiological distribution of HFMD and quantify the association of temperature with the incidence of children’s HFMD in Nanjing, China.@*Methods@#Daily counts of HFMD in children under 5 years and daily meteorological variables during 2011-2016 were obtained. Descriptive statistics were used to describe the epidemiological characteristics and distributed lag non linear model (DLNM) was used to assess the associations of temperature on HFMD cases.@*Results@#A total of 104 977 HFMD cases aged 0-5 years were reported in Nanjing during the study period and the male to female sex ratio was 1.49∶1. The average annual incidence was 213.5 per 100 000. A bimodal seasonal pattern was observed and the south and west were found to be the high incidence areas in the city. Of these laboratory confirmed enteroviruses positive cases, 32.5% cases were positive for EV-A71 infections, 29.1% cases were positive for CV-A16 infections and 38.4% cases were positive of other enteroviruses infections. The temperature HFMD relationships were non linear and showed obvious lag effects. The cumulative relative risk presented as an approximately inverted U shape over 14 days and peaked at 25.7 ℃ with value of 2.71(95%CI=1.93-3.81). Subgroup analyses revealed that males and children aged <1 year were more vulnerable to temperature variations.@*Conclusion@#Epidemiological characteristics of HFMD among children aged 0-5 years old in Nanjing presented temporal and regional distribution. The temperature has significant impact on children’s HFMD occurrence.

The effect of isosorbide dinitrate on cardiac function after cardiopulmonary resuscitation in a porcine model / 中华急诊医学杂志

Objective To assess the effect of isosorbide dinitrate on the improvement of cardiac function after cardiopulmonary resuscitation (CPR) by regulating myocardial cells apoptosis..Methods Total of 30 domestic pigs were divided into three groups randomly (random mumber) after anesthetization:the sham group (n=6),the control group (n=12),and the isosorbide dinitrate group (n=12).Cardiac arrest of ventricular fibrillation was induced by programed electrical stimulation in the control and isosorbide dinitrate groups.Isosorbide dinitrate was infused at the rate of 2 μg/(kg·min) in the isosorbide dinitrate group.Coronary perfusion pressure (CPP) and cardiac output (CO) were recorded at baseline,2,6,12 and 24 h after restoration of spontaneous circulation (ROSC).Myocardial enzyme and heart fatty acid binding protein (H-FABP) was tested at the same time points.At 24 h after ROSC,the animals were sacrificed to obtain the myocardium for pathological section and Western blot.The expression of Bcl-2,Bax and activated Caspase-3 were tested and apoptosis was tested by TUNEL and apoptosis index was calculated.Results Right atrial pressure (RAP) increased after ROSC and decreased in the isosorbide dinitrate group compared with the control group (P＜0.05).CPP at 12,24 h after ROSC and CO at 24 h after ROSC in the isosorbide dinitrate group increased significantly compared with the control group (both P＜0.05).HE staining revealed that the injury of myocardial cells was ameliorated in the isosorbide dinitrate group.Apoptosis index of the isosorbide dinitrate group significantly decreased than the control group [(37.8±15.5)％ vs (13.1±0.5)％,P＜0.05].The expression of Bax and activated Caspase-3 decreased while Bcl-2 and Bcl-2/Bax increased after ROSC in the isosorbide dinitrate group compared with the control group (all P＜0.05).Conclusions Isosorbide dinitrate could improve the isehemia/reperfusion injury and cardiac function after ROSC by inhibiting apoptosis regulated with Caspase-3 pathway.

Autologous bone marrow stem cell transplantation for liver cirrhosis via the hepatic artery in rabbits / 中国组织工程研究

BACKGROUND:How to make more transplanted bone marrow stem cel s stay and differentiate in the liver is an important issue, which is also crucial for treatment of liver cirrhosis via the hepatic artery. OBJECTIVE:To investigate the therapeutic effect of autologous bone marrow stem cel transplantation via the hepatic artery on liver cirrhosis. METHODS:Thirty New Zealand white rabbits were equivalently randomized into normal control, stem cel transplantation and model groups. Animal models of liver cirrhosis were made in the latter two groups. Then, model rabbits in the stem cel transplantation group were subjected to autologous bone marrow stem cel transplantation via the hepatic artery. Liver function of rabbits was detected in 1, 2, 4, 8, 10 weeks after cel transplantation, and pathological detection of the liver was performed in the 10th week. RESULTS AND CONCLUSION:At 10 weeks after cel transplantation, the liver function of the rabbits was improved significantly compared with the model group, including reduced activities of serum alanine aminotransferase, total bilirubin and aspartate aminotransferase, shortened activated partial thromboplastin time, and increased albumin level (P<0.05). Pathological examination of the liver showed that the liver cel s in the stem cel transplantation group were intact with no obvious edema and stil had the structure of the pseudolobule, and compared with the model group, the degree of liver fibrosis was significantly reduced in the stem cel transplantation group. Our experimental results show that the transplantation of autologous bone marrow stem cel s via the hepatic artery has a certain therapeutic effect on liver cirrhosis by increasing the body albumin content in a short time and improving the liver function.
