Efficacy of ultrasound-guided percutaneous transhepatic biliary drainage for acute obstructive suppurative cholangitis combined with septic shock.

Objectives: This study aimed to investigate the efficacy of ultrasound-guided Percutaneous Transhepatic Biliary Drainage (PTCD) for the treatment of Acute Obstructive Suppurative Cholangitis (AOSC) combined with septic shock due to choledocholithiasis, and its effect on inflammatory factors.

Methods: Clinical data of 86 patients with AOSC and septic shock admitted to our hospital between January 2019 and May 2021 were retrospectively analyzed and grouped according to different treatment methods. Among them, 43 patients who underwent Endoscopic Retrograde Cholangiopancreatography (ERCP) and Endoscopic Nasobiliary Drainage (ENBD) were included in the Control Group (CNG), and 43 patients who underwent ultrasound-guided PTCD were included in the Study Group (SG).

[Effects of selenium fertilization on selenium availability in rice soil.].

Selenium (Se) is easy to be fixed in acidic rice soil of South China, and thus its availability is low. The aim of this study was to investigate the influence of Se fertilizer on Se availability in rice rhizosphere and non-rhizosphere soils. The results showed that Se application increased yield and rice Se concentration.

The role of regulatory B cells in digestive system diseases.

Introduction: The past decade has provided striking insights into a newly identified subset of B cells known as regulatory B cells (Bregs). In addition to producing antibody, Bregs also regulate diseases via cytokine production and antigen presentation. This subset of B cells has protective and potentially therapeutic effects.
