MRCP Combined With CT Promotes the Differentiation of Benign and Malignant Distal Bile Duct Strictures.

Objective: To determine whether contrast-enhanced computed tomography (CT) can promote the identification of malignant and benign distal biliary strictures (DBSs) compared to the use of magnetic resonance cholangiopancreatography (MRCP) alone and to identify imaging findings of malignant DBSs.

Materials And Methods: A total of 168 consecutive patients with confirmed DBSs were reviewed. MRCP alone and MRCP combined with CT images were blindly analyzed by two radiologists (e.

Characteristics of Renal Function in Patients Diagnosed With COVID-19: An Observational Study.

The aim of the study was to analyze the characteristics of renal function in patients diagnosed with COVID-19. In this retrospective, single-center study, we included all confirmed cases of COVID-19 in a tertiary hospital in Guangdong, China from January 20, 2020 to March 20, 2020. Blood and urine laboratory findings related to renal function were summarized, and the estimated glomerular filtration rate (eGFR) and endogenous creatinine clearance (Ccr) were also calculated to assess the renal function.

[Prevention of poor incision healing after total knee arthroplasty].

Objective: To investigate the causes of poor incision healing after total knee arthroplasty(TKA) and to propose active preventive and therapeutic measures.

Methods: Total 284 patients undergoing unilateral TKA from September 2016 to June 2018 were enrolled in the study and divided into control group and observation group. Firstly, 150 patients with unilateral TKA from September 2016 to June 2017 were retrospectively analyzed and included in the control group.

[Arthroscopic medial patellofemoral ligament reconstruction combined with lateral retinacular release for recurrent patellar dislocation].

Objective: To evaluate the clinical results of the medial patellofemoral ligament (MPFL) reconstruction combined with the lateral retinacular release for the treatment of recurrent patellar dislocation.

Methods: From March 2011 to June 2013, 15 patients with recurrent patellar dislocation underwent arthroscopic MPFL reconstruction combined with the lateral retinacular release. The graft was autogenous semitendinosus and semimembranosus tendon.

[Treatment of lactic acidosis with early continuous blood purification].

Objective: To observe the therapeutic effect of early continuous blood purification (CBP) on lactic acidosis patients.

Methods: Using prospective randomized study method, 41 patients with lactic acidosis in intensive care unit (ICU) from January 2010 to April 2012 were randomly divided into CBP group (n=21) and control group (n=20). Among them, blood gas analysis, lactic acid, blood biochemistry were prospectively monitored at the time before treatment, 12, 24 and 72 hours after treatment.
