[Effect of total knee arthroplasty under computer navigation on intraoperative blood loss and joint function recovery].

Objective: To analyze the effect of computer navigation assisted total knee arthroplasty on intraoperative hemorrhage and postoperative joint function recovery in patients with knee osteoarthritis.

Methods: From February 2015 to December 2017, 65 patients with knee osteoarthritis treated by traditional total knee arthroplasty were retrospectively analyzed as the control group and 65 patients with knee osteoarthritis treated by total knee arthroplasty under computer navigation as the experimental group. Before operation, all patients showed red swelling pain of knee, pain of going up and down stairs, and pain and discomfort of waist when sitting up and standing up.

Microsurgical anatomy of the abducens nerve.

Objective: To clarify the oriented classification, relationships, and variations of the abducens nerve and provide a detailed description of its microsurgical anatomic features.

Methods: A microsurgical anatomic dissection of the abducens nerve was performed in 100 specimens obtained from 50 adult cadaveric heads fixed in formalin and two adult cadaveric heads stained with hematoxylin and eosin for histological examination. Important neurovascular and structural relationships of the abducens nerve were observed.

Microsurgical anatomy of the ocular motor nerves.

This study was designed to provide anatomic data to help surgeons avoid damage to the ocular motor nerves during intraorbital operations. The microsurgical anatomy of the ocular motor nerves was studied in 50 adult cadaveric heads (100 orbits). Dissections were performed with a microscope.

[Differentiation of hepatic oval cell into mature hepatocyte induced by hepatic stellate cells].

Objective: To investigate the role of hepatic stellate cells in the differentiation of hepatic oval cells into adult hepatocyte.

Methods: The oval cell were cocultured with primary hepatic stellate cells (HSC) in the same well (M-coculture) or separately cultured with HSC by millIcell (S-coculture). Oval cells were cultured alone as control; the expression of adult hepatocyte marker HNF-4alpha, albumin, and oval cell marker AFP, CK-19 in each group were detected by real-time PCR and western-blot.
