Objective Endoscopic ultrasound (EUS) guided fine-needle aspiration (FNA) of pancreatic lesions is being increasingly used. The aim of the study was to evaluate its safety, accuracy, and clinical utility in the diagnosis of pancareatic diseases. Methods EUS-guided FNA was performed in 21 patients (13 men and 8 women) with pancreatic lesions (16 head/neck, 5 body/ tail) detected by CT scanining, unltrasonography or clinically suspected diagnosis.Three patients with unresectable pancreatic cancer underwent EUS-guided celiac plexus neurolysis(CPN) for pain-relieving. Results The lesions detected by CT scanning (19 cases) and ultrasonography(16 cases) were all confirmed by EUS. Adequate specimens were obtained by EUS-guided FNA in 18 of 21 lesions and final diagnosis in these subjects was pathologically confirmed. EUS-guided FNA had a sensitivity of 85.0%, specificity of 100.0% and accuracy of 85.7% for diagnosis of pancreatic lesions. The final diagnosis was not obtained in three patients due to inadequate specimens. Three patients with pancreatic carcinoma were decreased in pain scores after EUS-CPN. Two cases with complication of mild pancreatitis or post-FNA fever were found. Conclusions EUS-guided FNA of the pancreas was a safe and effective modality for diagnosis and treatment of pancreatic lesions.

This article describes the nomenclature, history and genetic evolution of duck hepatitis A virus, and updates the epidemiology, clinical symptom and surveillances of duck virus hepatitis A. It also summarizes the present status and progress of duck virus hepatitis A and illustrated the necessity and urgency of its research, which provides rationale for the control of duck hepatitis A virus disease in China.

Objective:To study the distribution and drug resistance of Carbapenem-Resistant Organism (CRO) and to analysis the risk factors of CRO 30-day mortality.Methods:A total of 181 patients with CRO infection diagnosed in Department of Hematology, Fujian Medical University Union Hospital from January 2018 to June 2020 were retrospectively investigated. The clinical and laboratory data of the patients were collected, the prognosis of patients diagnosed with CRO infection in day 30 was followed up, and the risk factors of prognosis were analyzed. The clinical significance of Carbapenem-Resistant Enterobacteriaceae (CRE) active screening was further evaluated in the CRE subgroup.Results:Among the total of 181 CRO isolates, 47.2% were CRE, 37.0% were Pseudomonas aeruginosa, and 32.6% were Klebsiella pneumoniae, which were highly resistant to carbapenem and had high MIC value, 76.8% (139/181) of CRO were MIC of imipenem resistance≥16 μg/ml. The main sources of isolates were blood and sputum. The 30-day all-cause mortality rates of patients with CRO or CRE infection were (41.4±3.7) % and (44.7±5.4) %, respectively. The COX multivariate regression analysis showed that the level of procalcitonin >0.2 ng/ml and the MIC value of imipenem resistance ≥ 16 μg/ml were independent risk factors for 30-day mortality of CRO infected patients. The CRE subgroup analysis showed that MIC value of imipenem resistance ≥16 μg/ml were independent risk factors for 30-day mortality of CRE infected patients. The 30-day cumulative survival rate of patients with CRE active screening was higher than the patients without CRE active screening [ (68.0±9.3) % vs (50.0±6.5) %, P=0.21]. Conclusion:The high MIC value of imipenem resistance isolates seriously affects the prognosis of patients with CRO infection in the hematology department, and the mortality rate was high. CRE active screening is expected for early prevention, early diagnosis, and early treatment for high-risk patients.
