Objective:To explore the risk factors of hospital death in patients with acute Upper gastrointestinal bleeding, analyze the role of emergency endoscopy, and provide reference for grass-roots hospitals to carry out related work.Methods:A total of 370 patients with acute Upper gastrointestinal bleeding hospitalized in the Xinghua People′s Hospital from January to December 2022 were included, 278 of whom underwent emergency gastroscopy. The common causes and locations of acute Upper gastrointestinal bleeding were analyzed, and the influencing factors of death from acute upper gastrointestinal bleeding were analyzed by logistic regression.Results:Among 370 patients with acute Upper gastrointestinal bleeding, the majority were male [67.3%(249/370)], the median age was 70(57-78)years old, and the median hemoglobin level at admission was 72(57-96)g/L. Among them, 278 patients underwent gastroscopy, and 130 patients received blood transfusion treatment of 2(1.5-3.5)units of red blood cells transfusion. The median length of stay was 5(4-7)days. The age of the endoscopic group was younger than that of the non endoscopic group ( P<0.001), and the hemoglobin level was higher than that of the non endoscopic group ( P<0.001). The proportion of hemostatic drug use and blood transfusion was lower than that of the non endoscopic group ( P=0.027, P<0.001). In patients undergoing gastroscopy, the causes of upper gastrointestinal bleeding included 144 cases (51.8%) of ulcer related bleeding, 61 cases (22.0%) of bleeding caused by acute mucosal lesions, 27 cases (9.7%) of bleeding caused by tumors, 12 cases (4.3%) of bleeding caused by cardiac tears, 5 cases (1.8%) of bleeding caused by vascular malformations, and 29 cases (10.4%) of bleeding caused by varices. The bleeding sites included: 170 cases (61.1%) had bleeding from the stomach, 53 cases (19.1%) from the esophagus, 54 cases (19.4%) from the duodenum, and 1 case (0.4%) from gastroduodenal compound ulcer bleeding. Among all patients, 19 died in the hospital, and among 92 patients who did not undergo emergency gastroscopy, 16 died, with a mortality rate of 17.4%; Among 278 patients who underwent emergency gastroscopy, 3 died, with a mortality rate of 1.08%. Logistic single factor regression analysis found that the elderly (>70 years old), low hemoglobin (<70 g/L), blood transfusion and emergency gastroscopy were the influencing factors of hospital death in patients with acute upper gastrointestinal bleeding. Multivariate regression analysis showed that emergency gastroscopy ( OR=0.043, 95% CI: 0.010-0.198, P<0.001) could reduce the hospital death of patients with acute upper gastrointestinal bleeding. Conclusions:Acute upper gastrointestinal bleeding is common in elderly patients. On the basis of stable hemodynamics and early endoscopic examination, identifying the cause and combining traditional drugs for endoscopic hemostasis can improve the prognosis of patients and reduce the mortality of acute upper gastrointestinal bleeding.

ObjectiveTo evaluate the trauma care effect and the value of trauma and injury severity score (TRISS) in prediction of the mortality by using TRISS to calculate the survival probability of trauma patients in five hospitals from Zhejiang province in 2009.MethodsA retrospective study was done on trauma patients (study group) firstly admitted to Emergency Department of five hospitals from Zhejiang province in 2009.The relevant information was collected,including demographic data,trauma types and injury causes.The TRISS score was obtained through calculating injury severity score (ISS) and revised trauma score (RTS) on admission into emergency department.With the major trauma outcome study (MTOS) as control group,M value,standardized Ws value and 95% confidence interval (CI) were calculated to compare actual survival rate and anticipation survival rate.ResultsA total of 2 193 patients at mean age of 44.39 years were enrolled in the study,including 1 661 male patients (75.74%).Traffic accident injury was the most common,followed by fall injury.The mortality rate according to TRISS was 13.22%,but the actual mortality rate was 9.75%.For all the patients,M =0.80 indicated that the injury severity of the study group was significantly different from that of the control group.At the same time,Ws =2.15,95% CI for Ws:1.54-2.77 showed that the actual survival rate of the study group was significantly higher than that of the control group.Besides,the survival rate of trauma patients in the affiliated hospitals and three hospitals at class A grade was significantly higher fian that of the control group,but there was no significant difference between three hospitals at class B grade and control group. ConclusionsTRISS overestimates the mortality of the study group,which is probably associated with the rapid development of traumatology and the old coefficients of TRISS.Setting up local trauma database and renewing coefficients of TRISS may improve the ability of TRISS in predicting mortality of the trauma patients.

ObjectiveTo investigate the effect of factors correlated with trauma emergency care system on the length of ICU stay and figure out independent risk factors of prolonged ICU stay. Methods A total of 1 361 trauma patients admitted to the ICU of five tertiary hospitals in Zhejiang province in 2009 were retrospectively studied.Demographic data,time of ICU stay and variables related to trauma care were collected.Logistic regression was performed to determine the independent risk factors of prolonged ICU stay ( ≥ 15 days). ResultsOverall,192 trauma patients ( 14.1% ) had a prolonged ICU stay ( ≥15 days).Single factor analysis indicated that ISS≥ 16 points,GCS≤7 points,blunt trauma,prehospital emergency care,length of emergency department stay ≥4 hours,mechanical ventilation and central venous pressure monitoring were associated with the prolonged ICU stay.Multivariate analysis showed that pre-hospital emergency care was a protective factor for the prolonged ICU stay( ≥ 15 days) and that mechanical ventilation,length of emergency room stay≥4 hours and ISS≥ 16 points were the independent risk factors for the prolonged ICU stay ( ≥ 15 days).Conclusions Pre-hospital emergency care and ICU care show significant influence on the length of ICU stay.Furthermore,shortened length of emergency department stay is also contributive to reduced length of ICU stay.

Objective To explore risk factors in the mortality of casualties and to find a way to improve trauma emergency service. Method The possible factors likely related to the mortality of casualties were taken into account based on each stage of trauma emergency so as to find the independent risk factors by using univariate and multivariate analyses. Results A total of 3 659 casualties were enrolled in this study.Of them, 226 casualties died and the mortality rate was 6.18%. Following factors were related to mortality after univariate analysis: age, cause of trauma, injury severity score, Glasgow come scale come on the scene, professional emergency treatment on the scene, intubation in the ambulance, debridement and hemostasis in the ambulance, low blood pressure at admission, closed drainage of pleural cavity, emergency operation, CVP monitoring in ICU and mechanical ventilation in ICU. After multivariate analysis, six factors were independently related to the mortality of casualties as follows: Glasgow coma scale, injury severity score, mechanical ventilation, blood pressure at admission, age and professional emergency treatment on the scene. Conclusions It has a great significance to investigate the risk factors of mortality for casualties. Severity of trauma and age were independently associated with the outcomes of trauma. Besides, improving prehospital care and stabilizing the trauma patients in early phase can further decrease the mortality.

Objective To analyze the gene expression of pathogenic factors in vaginal secretions of patients with vulvovaginal candidiasis by using Oligo chips. Methods RNA was extracted from vaginal secretions of 10 patients with vulvovaginal candidiasis and 3 asymptomatic carriers, and hybridized with oligonuscreened followed by a bioinformatic analysis. Results Comparing with the asymptomatic carriers, the patients showed a higher expression of 44 genes and lower expression of 17 genes. Of these differentially expressed (TLR) 4, HWP1, SAP2, SAP5, LIP4, EFG1 and CPH1 were highly expressed in more than 80% of the secretion samples from patients with an average ratio of 4.013, while LIP6 and WH11 were lowly expressed in more IFN-γ and TLR4 were associated with native immunity, HWP1 associated with hyphal adhesion and formation, SAP2, SAP5, LIP4 and LIP6 associated with extracellular hydrolysis, and EFG1, CPH1 and WH11 associated with phenotypic switching. Conclusions Both the host adaptive immunity deficiency and increased virulence of Candida species are involved in the pathogenesis of vulvovaginal candidiasis, and TLR4 possibly plays a certain role in the local immunity of patients with this entity.

Objective To determine risk factors in nosocomial infection of trauma patients during intensive care unit stay. Methods A retrospective study was carried out. A total of 1103 trauma patients admitted to the intensive care unit of five tertiary hospitals in Zhejiang Province in 2009 were reviewed. Demographic data, injury severity score and other variables related to the trauma services were collected. Univariate and multivariate analysis were processed to identify the independent risk factors of nosocomial infection in trauma patients during stay in intensive care unit. Results Overall, 171 patients( 15.5% )developed nosocomial infection during ICU stay. Of 1103 patients, 157 patients (14.2% ) died, and the 59 fatal patients were from infection group. The mortality rate in infection group was 34.7% , which was significantly higher than that in non - infection group (10.5% ). The independent risk factors of nosocomial infection in all the patients determined by using multivariate analysis included central venous monitoring, mechanical ventilation, age ≥65, the length of ICU stay > 14 days and injury severity score ≥ 16. For the severe trauma patients, central venous monitoring, mechanical ventilation, the length of ICU stay > 14 days were independent risk factors of nonsocomial infection. Conclusions The severity of injury, age, the length of ICU stay and invasive procedures were related to the nosocomial infection. To standardize the invasive procedures and to reduce the length of ICU stay may decrease the infection rate of trauma patients.
