Résumé
Objective To evaluate the serum Prostaglandin E2 (PGE2) level in Acute-on-chronic liver failure (ACLF) and determine its predicative value for infection. Methods From April 2014 to April 2015, ninety-one patients with hepatitis B virus and ACLF but without infection were enrolled into this prospective study that was carried out at our Hospital. Twenty patients with stable chronic hepatitis B were enrolled from the outpatient department and twenty healthy control subjects without any disease were enrolled from hospital staff. Serum PGE2 levels were determined using ELISA at enrollment. Clinical and laboratory parameters were collected. Receiver operating characteristic (ROC) curves were used to determine optimal cut-off values to predict infection. Results Significantly higher PGE2 levels were found in patients with ACLF in comparison with healthy controls and patients with stable CHB (P < 0.000 1). In ACLF patients, PGE2 levels were significantly higher in patients that eventually developed infection than those without this complication (P < 0.000 1). ROC analysis showed that serum PGE2 (area under the ROC curve, 0.83) could predict infection in patients with ACLF with sensitivity of 78.4% and specificity of 81.5% using a threshold of 141 pg/mL. Conclusions Serum PGE2 is associated with the susceptibility to secondary infections for patients with ACLF. Increased PGE2 serum levels may serve as a potential biomarker for developing infections in ACLF patients.

Résumé
This article describes the development of an innovative microcomputerized pulse-water-sac massage with drug penetration instrument and reports its effectiveness in the patients with immunity infertility accompanied by chronic seminal vesiculitis. The instrument was developed on the basis of the pathological characteristics of immunity infertility accompanied by chronic seminal vesiculitis, and along the lines of our practice in integrating the modern theory of traditional Chinese medicine, with multiple techniques of biomedical engineering sciences. 181 male patients with immunity infertility accompanied by chronic seminal vesiculitis received the treatment. Of these cases, 135(74.6%) were cured, 37(20.4%) were treated with significant therapeutic effects and 9(5.0%) with improved effects. The results of antisperm antibody (AsAb) tests became negative in 85.6% of the patients after treatment, and the pregnancy rate of their wives was 49.1%. No mild adverse effects were observed in all cases.
