Background: The benefits of non-invasive ventilation (NIV) in chronic obstructive pulmonary disease (COPD) have been debated for many years due to the conflicting results observed in these patients. The aim of this metaanalysis was to assess the long-term effects of NIV in stable patients with COPD. Methods: The Cochrane Central Register of Controlled(More)
OBJECTIVE The aim of this study was to investigate the effect of Xiaozhi decoction (XZD) on posthemorrhoidectomy pain and analgesic medication consumption. METHODS From May 2013 to March 2015, 315 patients who underwent open hemorrhoidectomy in our hospital were enrolled in this study, of whom, 160 patients were randomly assigned to accept sitz bath with(More)
OBJECTIVE To explore the effect of anterior cruciate ligament (ACL) rupture on the biomechanics of medial collateral ligament (MCL). METHODS Six fresh human knee joints were fixed on the self-made fixture and flexed 90 degrees . ACL was divided into a normal group, an anteromedial bundle (AMB) break group, and an ACL complete break group. 800N burden was(More)
In this model, ψ is the geostrophic pressure, also called the geostrophic stream function, ξ = Δψ is the vertical component of the relative vorticity, ∇⊥ψ = (−∂ψ/∂y, ∂ψ/∂y) is a zeroth-order balance in the momentum equation, and F, β, and R e are the rotational Froude number, the Coriolis parameter, and the Reynolds number, respectively. Usually, ] = 1/R e(More)
BACKGROUND The aim of this study was to provide valid data for a plate-screw fixation model for fractured posterior-anterior columns of the acetabulum. MATERIAL AND METHODS Nineteen cadaveric bony hemi-pelvis specimens were obtained and 50 healthy adults were enrolled. The modified Stoppa approach and computed tomography (CT) imaging were used to collect(More)

OBJECTIVE To evaluate the effect of abducens orthosis combined with walker on developmental dysplasia of the hip (DDH). METHODS A total of 126 patients (224 hips) with DDH aged 6-36 months in Xiangya Hospital was randomly divided into 2 groups: an orthosis combined with walker group and an improved hip frog cast fixation group. Seventy patients (130 hips)(More)
OBJECTIVE To investigate the effect of the anterior cruciate ligament (ACL) rupture on the biomechanics of the lateral collateral ligament (LCL). METHODS The specimens in this experiment were knee joints from 6 normal fresh adult male cadavers which was donated voluntarily, aged of 26-35 years with an average of 31.4 years. The knee joints were(More)
