Objective The purpose of this study was to investigate the value of serum galactomannan (GM) in the diagnosis of invasive pulmonary aspergillosis (IPA) in patients with chronic obstructive pulmonary disease (COPD).Methods We enrolled 60 COPD patients in the study, including 19 IPA and 41 non-IPA cases.We examined serum GM of the patients by ELISA, evaluate the value of serum GM test for the diagnosis of IPA in patients with COPD, and compared the GM values before and after treatment.Results With 0.5 as the positive cutoff value, the sensitivity, specificity, positive predictive value, and negative predictive value of serum GM were 57.9%, 95.3%, 84.6%, and 83.0%, respectively, with a high specificity and a low sensitivity.The 7 IPA cases showed a significantly decreased GM value after treatment as compared with the baseline (0.30±0.21 vs 1.48±1.37, P=0.004).Conclusion The serum GM test has a limited value in the diagnosis of IPA in patients with COPD, but dynamic monitoring of the changes of the serum GM value may help evaluate the patient's condition.

Purpose To explore the value of Doppler ultrasound in the diagnosis of congenital hypertrophic pyloric stenosis (CHPS) by observing pylorus. Materials and Methods Sixyt-five children with CHPS diagnosed by ultrasound in Neonatology Department of Guangzhou First People's Hospital from 2006 to 2015 were retrospectively analyzed. CHPS group and 50 infants in control group were examined by Doppler ultrasound to observe the features of blood flow distribution and blood flow grading, and Doppler spectrum analysis was performed to observe contrast agent passing through pyloric canal. Results The difference of the thickness of muscular layer and mucous layer, and that of the long diameter and inner diameter of pyloric canal in CHPS group and control group all suggested marked statistical significance (P<0.01); the blood flow grading in muscular layer and mucous layer between the two groups showed statistical significance (t=13.33 and 18.77, all P<0.01). The blood flow velocity in muscular layer of CHPS group was (16.96±0.91) cm/s, resistance index (RI) 0.68±0.33, inner diameter of pyloric canal (1.98±0.33) mm. Conclusion Doppler ultrasound enables us to grasp the distribution and grading of blood flow of pylorus as well as the condition of contrast agent passing through pyloric canal, in which way the degree of pyloric stenosis can be evaluated by combining indexes such as Vmax and RI, and an objective basis for clinical choice of treatment can be provided, possessing high application value.
