ABSTRACT
Epstein -Barr virus hepatitis is liver inflammation caused by Epstein -Barr virus infection, mainly self -limited hepatitis or mild or moderate liver injury.It often has good prognosis, but it may progress to chronic liver disease, severe hepatitis, and even intrahepatic cholangiocarcinoma.The clinical manifestations and histopathological features of this disease lack specificity , which may lead to missed diagnosis or misdiagnosis, and thus it should be taken seriously by clinicians .This article introduces the mechanism of Epstein -Barr virus infection and reviews the research advances in Epstein -Barr viral hepatitis.
ABSTRACT
Objective To investigate antimicrobial resistance of Escherichia coli (E.coli)and Klebsiella pneumoniae (K.pneumoniae),antimicrobial use density(AUD),as well as relation between antimicrobial resistance and AUD in a ter-tiary first-class hospital.Methods Antimicrobial resistance rates of clinically-isolated E.coli and K.pneumoniae,AUD of carbapenems and quinolones,as well as relation between resistance and AUD in 2013-2015 were statistically analyzed. Results Correlation analysis of antimicrobial resistance of bacteria and AUD showed that the decrease in resistance rate of E.coli to levofloxacin was related to the decrease in the use density of quinolones(r=0.61,P=0.03);increase in resist-ance rate of K.pneumoniae to imipenem was related to the increase in the use density of carbapenems(r=0.78,P<0.01). Conclusion Antimicrobial use is one of the causes of bacterial resistance,management on antimicrobial use needs to be strengthened to reduce the threat of bacterial resistance to human health.
ABSTRACT
Objective To evaluate the direct economic loss due to surgical site infection(SSI)from a medical eco-nomics perspective,and provide basis for health administrative departments to make strategies.Methods SSI in pa-tients undergoing breast,stomach and colorectal operation between March 2008 and February 2010 were selected for 1∶1 case-control study,patients with SSI were as SSI group,without SSI during the same period were as control group,difference in medical expense and length of stay between two groups were compared,economic loss due to SSI was evaluated.Results A total of 1 523 operation cases were investigated,75(4.92%)developed SSI.69 effec-tive pairings were obtained.Wilcoxon signed rank test revealed that difference in medical expense between two groups was statistically significant(Z =6.586,P <0.001),the median of average medical expense of SSI group was 6 828.60 yuan higher than control group,all kinds of medical expense in SSI group were all higher than control group;the median length of stay of SSI group was 10 days longer than that of control group (Z = 5.939,P <0.001).Conclusion SSI can prolong hospitalization,increase medical expense,decrease bed turnover rate,and in-fluence economic income and medical quality.
ABSTRACT
Objective To evaluate the effect of bundle intervention measures on preventing ventilator-associated pneumonia (VAP).Methods Patients who were admitted to an intensive care unit(ICU)of a hospital from January 2012 to December 2013 were monitored,patients from January to December 2012 were as control group,while from January to December 2013 were as intervention group (bundle intervention measures were implemented).Usage rate of ventilators and incidence of VAP between two groups were compared.Results A total of 4 560 patients were mo-nitored,2 608 in intervention group and 1 952 in control group.Usage rate of ventilators in intervention group was lower than control group (53.95% vs 61 .17%;χ2 =65.756,P <0.01).Incidence of VAP per 1 000 ventilator days in intervention group was lower than control group (13.00‰ vs 19.56‰;χ2 =4.649,P =0.031 ).Percentage of late-onset VAP per 1 000 ventilator days in tervention group was higher than control group(41 .82‰ vs 24.59‰). Conclusion Bundle intervention measures are helpful for reducing the incidence of VAP in ICU patients.
ABSTRACT
OBJECTIVE To analyze the bacterial distribution and drug resistance in lower respiratory tract nosocomial infection(NI).METHODS To investigate 351 patients suffered from lower respiratory tract NI using the prospective monitoring methods,and doing the pathogenic bacterium cultivation for sputums of 351 patients and then taking the susceptibility test.RESULTS Totally 346 pathogenic bacteria were found in sputums of 351 patients.The major pathogenic bacteria were Pseudomonas aeruginosa,Escherichia coli,Klebsiella and Staphylococcus aureus.ESBLs were 36.0% and 40.0%,respectively in E.coli and Klebsiella,and MRSA were 82.1% in S.aureus.Drug resistances were common in Gram-negative bacilli(GNB) and Gram-positive cocci.Piperacillin/tazobactam and cefoperazone/sulbactam and imipenem were the most sensitive for GNB,S.aureus,S.epidermidis and Enterococcus were all sensitive to vancomycin.CONCLUSIONS Drug resistance of the pathogenic bacteria in lower respiratory tract NI is common,so it′s necessary to emphasize pathogenic bacterium monitoring and use the antibacterials exactly.
ABSTRACT
Objective To study the necessirity of endocrine treatment for thyroid adenoma after operation. Methods TSH receptors were determined in 100 patient's thyroid adenoma specimens with SP method. The continuous pathologic sections of the thyroid tissues around the tumor were examined to find out that if there was any small focus. The patients were divided into two groups radnomly: Group A, patients received thyroid hormone(TH) treatment after operation; Group B, the patients received no TH treatment after operation. Blood T 3, T 4 and TSH concentration were determined, and the residual thyroid was examined with 131 I scanning and ultrasunography peroidically after operation. Results TSH receptors were presented in all of the thyroid adenomas, and small focus presented in 8% of the patients. Blood T 3, T 4, TSH and residual thyroid were normal in all patients in group A. In group B, Blood T 3, T 4 were below the normal lever in 45(90%), TSH over normal lever in 41(82%),residual thyroid hyperplasia and enlargement were found in 48 patients(96%), and thyroid nodule or tumor in 33(66%). Conclusions TH should be taken in patients with thyroid adenoma after operation to prevent high TSH of serum and tumor replapse, because these patients have the characteristics of muttiple focuses of tumor and postoperative hypothyroidism.
