Effects of Combined Spinal-Epidural Analgesia during Labor on Postpartum Electrophysiological Function of Maternal Pelvic Floor Muscle: A Randomized Controlled Trial.

Objective: Combined spinal-epidural analgesia (CSEA) is sometimes used for difficult births, but whether it contributes to postpartum pelvic muscle disorder is unclear. This randomized controlled trial examined whether CSEA given during labor affects the electrophysiological index of postpartum pelvic floor muscle function.

Methods: A consecutive sample of primiparous women who delivered vaginally at term were randomly assigned to a CSEA group (n = 143) and control group (n = 142) between June 2013 and June 2014.

[Effects of LFA-1 costimulation on proliferation and IgG production of PBMCs from lupus nephritis patients].

Aim: To study the effect of lymphocyte function associated antigen-1(LFA-1) costimulation on proliferation and immunoglobin production of peripheral blood mononuclear cells(PBMCs) form lupus nephritis(LN) patients.

Methods: 29 LN patients were enrolled in this study, and 12 healthy persons served as control. PBMCs from LN patients and healthy persons were obtained by Ficoll density gradient centrifugation, and cell proliferation was detected by (3)H-TdR incorporation.

[Surgical treatment for pigmented villonodular synovitis].

Objective: Pigmented villonodular synovitis(PVS) is a synovial proliferative disorder that remains a diagnostic difficulty. In this retrospective study we evaluated the diagnostic procedures, clinical symptoms and surgical treatment of PVS.

Methods: Six surgically treated cases of PVS were evaluated: five of the lesions were located in the knee joint and one in the hip joint.
