ABSTRACT

Pancreatic duct stones are one of the benign pancreatic diseases. It is often combined with chronic pancreatitis. The disease will progress to pancreatic cancer without timely treatment, thus reducing the quality of life of patients and seriously affecting their physical and psychological health. In recent years, with the development of imaging technology, the detection rate of pancreatic duct stones has been increasing year by year. This article reviewed the etiology, diagnosis and treatment strategies for pancreatic duct stones in recent years.

ABSTRACT

Objective:To construct a Nomogram model in predicting recurrence-free survival (RFS) and overall survival (OS) at six months, one year and two years after hepatocellular carcinoma (HCC) resection by using inflammatory markers combined with other routine clinical indicators.Methods:The data of 314 patients with HCC who underwent first time hepatectomy at Beijing Chaoyang Emergency Rescue Center and Air Force Characteristic Medical Center from January 2013 to January 2018 were analyzed. HCC patients who underwent hepatectomy at the First Medical Center of PLA General Hospital from January 2011 to January 2016 ( n=106) were used as the external validation group. Univariate and multivariate Cox proportional risk model was used to analyze independent risk factors of recurrence and death in HCC patients. A Nomogram model was constructed based on independent risk factors. Validation of the efficacy of the Nomogram model was done based on external data. Results:In the experimental group, 174 patients relapsed. The median RFS was 26 months. The 6 months, 1 year and 2 years RFS were 26.8%, 43.9%, and 68.8%, respectively. A total of 142 patients had died. The median survival time was 30 months. The 6 months, 1 year and 2 years OS were 5.9%, 23.6% and 63.1%, respectively. In the external validation group, 63 patients had developed recurrence, with a median RFS time of 28 months. The 6 months, 1 year and 2 years RFS were 26.4%, 45.3%, 54.7%, respectively. The median survival time was 31 months. The 6 months, 1 year and 2 years OS were 7.5%, 25.5%, 46.6%, respectively. Tumor size (>6.0 cm, HR: 1.447), vascular invasion ( HR: 1.408), TBil (>0.94 mg/dl, HR: 1.949), NLR (>2.54, HR: 2.843), AGR (≤0.88, HR: 2.447) were independent risk factors of HCC recurrence ( P<0.05). Tumor size (>6.0 cm, HR: 2.207), vascular invasion ( HR: 1.529), and NLR (>2.54, HR: 2.708) were independent risk factors of death for HCC patients ( P<0.05). The C-indexes of half-year, one-year and two-year RFS were 0.764 (95% CI: 0.677-0.854), 0.710 (95% CI: 0.615-0.824) and 0.673 (95% CI: 0.601-0.786), respectively. The C-indexes of half-year OS, one-year OS and two-year OS were 0.729 (95% CI: 0.648-0.841), 0.708 (95% CI: 0.608-0.813) and 0.664 (95% CI: 0.618-0.771), respectively. Conclusion:In this study, the construction of a Nomogram model in predicting prognosis of HCC patients was helpful to guide clinicians in improving preoperative treatment plans and in providing ideas for individualized treatment of patients.

ABSTRACT

Objective To investigate the feasibility of modified rapid Carba NP test for the detection of carbapenemase,and analyze the differences between the modified method and Carba NP test.Methods A total of 264 strains of gram-negative bacillus,including 164 carbapenem-resistant strains and 100 sensitive strains,were collected,and their carbapenemase were detected by Carba NP test and the modified rapid Carba NP test,respectively.The differences between the two tests were evaluated based on PCR as a reference.Results Among 164 carbapenem-resistant strains,carbapenemase gene was detected in 144 strains by PCR.The carbapenemase gene was negative in 100 sensitive strains.Among 164 carbapenem-resistant strains,135 were positive for the Carba NP test,while 130 for the modified rapid Carba NP test.One hundred of sensitive strains were negative for the two Carba NP tests.Compared with the results of PCR,the sensitivity,specificity and Kappa value of the Carba NP test were 91.7% (132/144),97.5% (117/120) and 0.886,respectively,while those of the modified rapid Carba NP test were 89.6% (129/144),99.2% (119/120) and 0.879,respectively.There was no significant difference in the positive rates between Carba NP test and the modified rapid Carba NP test (x2 =1.45,P > 0.05).Conclusion The modified rapid Carba NP test which has high consistency with the PCR method,is faster and cheaper than the Carba NP test,and may be applied to epidemiologic survey and the early monitoring of nosocomial infections.

ABSTRACT

Objective To evaluate the application value of inhibitor enhanced modified carbapenemase inactivation method (imCIM) in the detection of class B carbapenemase.The differences between imCIM and EDTA disc potentiation test (EDPT) were comparatively analyzed.Methods A total of 181 strains of carbapenem insensitive strains were collected,among which there were 44 strains of Klebsiella pneumoniae,44 strains of Escherichia coli,43 strains of Acinetobacter baumannii and 50 strains of Pseudomonas aeruginosa.The 83 strains of carbapenem-sensitive strains were composed of 25 strains of Klebsiella pneumoniae,16 strains of Escherichia coli,25 strains of Acinetobacter baumannii and 17 strains of Pseudomonas aeruginosa.The class B carbapenemase in the 264 strains of pathogenic bacteria was screened by imCIM and EDPT,and PCR results were used as gold standard.The statistical analysis wasperformed with consistency check,related-sample Wilcoxon signed rank sum test,independent samples Kruskal-Wallis H test and ROC curve.Results Among the 181 strains of carbapenem insensitive strains,PCR results of 144 strains were positive for drug resistance gene.The samples of class A,B and D of carbapenemase were 39,77 and 28 strains respectively.The results of imCIM showed that 70 strains were positive,and the other 111 strains were negative.The imCIM results of 166 strains were consistent with those of PCR.The results of EDPT showed that 72 strains were positive,and the other 109 strains were negative.The EDPT results of 134 strains were consistent with those of PCR.The results of PCR,EDPT and imCIM of 83 carbapenem sensitive strains were negative.The sensitivity and specificity of imCIM were 85.71% (66/77) and 97.86% (183/187),and the value of Kappa was 0.859.The sensitivity and specificity of EDPT were 66.23 % (51/77) and 88.77 % (166/187),and the value of Kappa was 0.561.The difference of inhibition zone of imCIM (AdimCIM) was different from EDPT(AdEDPr) and the difference was statistically significant (Z =-6.941,P < 0.05).In the imCIM detection,the AdimciM level of class B carbapenemase showed different population distribution position from class A and D carbapenemase with the statistically significant difference (x2 =108.887,P < 0.05).The areas under the ROC curve of imCIM and EDPTwere 0.988 (95%CI:0.977 to0.999) and0.936 (95%CI:0.909 to0.963),respectively.Conclusion imCIM should be accurate,efficient and convenient for screening of carbapenem phenotype for its high sensitivity and specificity,and suitable for epidemiological monitoring.

ABSTRACT

Since Shaw et al,first reported the first case successfully treated by veno-venous bypass (VVB),there has been great controversy on the routine application of VVB during conventional liver transplantation and piggyback liver transplantation in recent decades.With the improvements on the surgical skills,surgical techniques and anesthesiology,only a small portion of patients have the indications for VVB in liver transplantation routinely.This article reviews the current publications in this topic,which may provide new insight into the liver transplantation in clinical practice.
