[Clinical observation of arthroscopic single channel treatment of carpal tunnel syndrome with self-made instruments].

Objective: To investigate the efficacy of self-made arthroscopic single channel in the treatment of carpal tunnel syndrome.

Methods: Sixty patients with primary carpal tunnel syndrome treated from January 2014 to December 2019 were divided into arthroscopic group and traditional open operation group. There were 30 cases in arthroscopic group, including 12 males and 18 females, aged (47.

[Comparison of the efficacy of total arthroscopy and traditional surgical treatment for the treatment of popliteal cyst].

Objective: To compare the clinical efficacy of total arthroscopic surgery and traditional surgery for popliteal cyst.

Methods: From August 2014 to July 2017, 60 cases of popliteal cyst were treated with total arthroscopy or traditional surgery respectively. In total arthroscopy group, there were 30 patients including 7 males and 23 females with an average age of (55.

[Short term effect of total hip arthroplasty through direct anterior approach for the treatment of ankylosing spondylitis with hip flexion deformity].

Objective: To investigate the short term clinical efficacy of direct anterior approach(DAA) total hip arthroplasty for the treatment of ankylosing spondylitis with hip flexion deformity.

Methods: From September 2014 to June 2017, 15 cases of ankylosing spondylitis with flexion deformity of the hip were treated with total hip arthroplasty through DAA approach including 12 males(17 hips) and 3 females(4 hips) with an average age of 34.4 years old ranging from 21 to 57 years old.

Overexpression of miR‑214 promotes the progression of human osteosarcoma by regulating the Wnt/β‑catenin signaling pathway.

The aberrant expression of microRNA (miR)‑214 contributes to the regulation of normal and cancer cell biology, and is associated with human malignancies, however, it can operate in a contradictory manner. The role of miR‑214 in osteosarcoma remains to be fully elucidated. The aim of the present study was to investigate the effects of miR‑214 on osteosarcoma progression and tumor cell proliferation, and examine the molecular mechanism underlying osteosarcoma.

[Expression of hypoxia inducible factor-1alpha in long bone development].

Objective: To observe dynamically the development of fetal long bone and detect the expression and distribution of HIF-1alpha,to investigate the expression pattern and possible effects of hypoxia inducible factor-1alpha (HIF-1alpha) in fetal long bone development of mouse.

Methods: E12.5, E13.

[Expression of hypoxia inducible factor-1alpha in the fetal vertebra development: experiment with mice].

Objective: To explore the expression pattern and effects of hypoxia inducible factor-1alpha (HIF-1alpha) in the fetal vertebra development.

Methods: Fetuses at different developmental stages were obtained from C57BL6 mice. The vertebrae of the fetuses were isolated and the development of vertebra was observed by stereoscopic and light microscope.
