OBJECTIVE To investigate the status of traumatic infection among earthquake in order to provide reasonable evidence for anti-infective therapy. METHODS Samples were collected from 14 patients with compound fracture or osteofascial compartment syndrome for bacterial,fungal and anaerobic culturing,then according to pathogens to choose antimicrobial susceptibility test (AST). RESULTS Among 14 victims,10 had germ growth in wound secretions,the infection rate was 71.43%. Among 17 samples the bacteria,fungi and anaerobic were isolated in 12,4 and (samples,respectively),the isolated rates were 70.59%,23.53% and 5.89%. The main pathogens for the first culture were Enterobacter cloacae,coagulase negative Staphylococcus (CNS) and Acinetobacter. The Clostridium tetani and C. perfringens were all negative. We also isolated 5 strains of fungi from them 1 strain of Candida. CONCLUSIONS Most of the victims from disaster area have got bacterial infection. Most of them are combined infection,some of the infections are nosocomial infections. The key points of the treatment are to find pathogens immediately and choose a reasonable antibacterial agents according to the AST.

Objective To investigate the association between liver pathological changes and clinical features in patients with chronic HBV infection and alanine aminotransferase (ALT) 1-2 × upper limits of normal (ULN).Methods A total of 80 patients with chronic HBV infection and ALT 1-2 × ULN who were hospitalized in The First Affiliated Hospital of Bengbu Medical College from July 2015 to December 2016 were enrolled.All patients underwent liver biopsy,and according to positive or negative HBeAg,these patients were divided into two groups,and the association of liver pathological changes with age,sex,and HBV DNA load was analyzed.The t-test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.Results The HBeAg-negative group had significantly higher age and serum ALT level than the HBeAg-positive group (t =12.35 and 7.18,both P < 0.01).Compared with the HBeAg-positive group,the HBeAg-negative group had a significantly higher proportion of patients with liver inflammation ≥G2 (54.8% vs76.3%,x2 =53.68,P<0.01) or fibrosis degree ≥S2 (57.1% vs 73.7%,x2 =46.67,P<0.01).Immunohistochemical staining was performed for 35 patients to measure the expression of HBsAg and HBcAg in the liver,and there were no significant differences in the staining scores of HBsAg and HBcAg between the two groups (both P > 0.05).Conclusion Among patients with chronic HBV infection and slightly elevated ALT,HBeAg-negative patients have significantly worse conditions of liver lesions than HBeAg-positive patients.Liver biopsy is recommended for older patients with a long course of disease,in order to provide guidance for antiviral therapy.

The multiplex polymerase chain reaction (PCR) technique was applied to detect the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) specific target cDNA fragments in the present study. The target cDNA fragments of SARS-CoV were synthesized artificially according to the genome sequence of SARS-CoV in GenBank submitted by The Chinese University of Hong Kong, and were used as simulated positive samples. Five primers recommended by World Health Organization (WHO) were used to amplify the fragments by single PCR and multiplex PCR. Three target cDNA fragments (121, 182 and 302 bp), as well as the three different combinations of any two of these fragments, were amplified by single PCR. The combination of these three fragments was amplified by multiplex PCR. The results indicated that the multiplex PCR technique could be applied to detect the SARS-CoV specific target cDNA fragments successfully.

Objective:To analyze the clinical application value of serum heme oxygenase (HO)-1expression level in non-alcoholic fatty liver disease (NAFLD) and, based on that, establish a diagnostic model combined with glucose regulatory protein 78 (GRP78) so as to clarify its diagnostic effectiveness and application value.Methods:A total of 210 NAFLD patients diagnosed by abdominal B-ultrasound and liver elastography were included, and at the same time, 170 healthy controls were enrolled. The general clinical data, peripheral blood cell counts, and biochemical indicators of the research subjects were collected. The expression levels of HO-1 and GRP78 were detected using an enzyme-linked immunosorbent assay. Multivariate analysis was used to screen independent risk factors for NAFLD. Visual output was performed through nomogram diagrams, and the diagnostic model was constructed. Receiver operating characteristic curve (ROC), calibration curve, and decision curve analysis (DCA) were used to evaluate the diagnostic effectiveness of NAFLD. Measurement data were analyzed using a t-test or Mann-Whitney U rank sum test to detect data differences between groups. Enumeration data were analyzed using the Fisher's exact probability test or the Pearson χ2 test. Results:Compared with the healthy control group, the white blood cell count, aspartate aminotransferase (AST), alanine aminotransferase, gamma-glutamyl transferase (GTT), fasting blood glucose (Glu), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), serum HO-1, and GRP78 levels were significantly increased in the NAFLD group patients ( P ?0.05). Binary logistic analysis results showed that AST, TG, LDL-C, serum HO-1, and GRP78 were independent risk factors for NAFLD ( P ?0.05). A nomogram clinical predictive model HGATL was established using HO-1 (H), GRP78 (G) combined with AST (A), TG (T), and LDL-C (L), with the formula P=-21.469+3.621×HO-1+0.116 ×GRP78+0.674×AST+6.250×TG+4.122 ×LDL-C. The results confirmed that the area under the ROC curve of the HGATL model was 0.965?8, with an optimal cutoff value of 81.69, a sensitivity of 87.06%, a specificity of 92.82%, a P ?0.05, and the diagnostic effectiveness significantly higher than that of a single indicator. The calibration curve and DCA both showed that the model had good diagnostic performance. Conclusion:The HGATL model can be used as a novel, non-invasive diagnosis model for NAFLD and has a positive application value in NAFLD diagnosis and therapeutic effect evaluation. Therefore, it should be explored and promoted in clinical applications.

Sarcopenia is one of the manifestations of malnutrition in patients with liver cirrhosis. Most studies have shown that sarcopenia is associated with overt hepatic encephalopathy (OHE), leading to an increased risk of events such as reduced quality of life, poor clinical prognosis, and even death in patients with liver cirrhosis, but there are few studies on the association between sarcopenia and minimal hepatic encephalopathy (MHE). This article reviews the research advances in sarcopenia and hepatic encephalopathy to provide a reliable basis for clinical treatment, and it is pointed out that the nutritional status of patients can be improved to prevent MHE and even reduce the onset of OHE, thereby improving patient prognosis, increasing quality of life, and reducing the risk of death.
