Ilizarov technique for treatment of a giant aneurysmal bone cyst at the distal femur: A case report.

Background: Aneurysmal bone cyst (ABC) is a benign cystic of unknown etiology, characterized by multiple chambers and a high recurrence rate. Current treatment options include vascular embolization, surgical excision, curettage with cavity filling, sclerosing agent injection into the cavity, radiotherapy, and systemic drug therapy. Among these, surgical excision and curettage are the preferred treatment modalities.

Prognosis value of Chinese Ocular Fundus Diseases Society classification for proliferative diabetic retinopathy on postoperative visual acuity after pars plana vitrectomy in type 2 diabetes.

Aim: To compare the postoperative visual acuity among eyes with proliferative diabetic retinopathy (PDR) of different stages after pars plana vitrectomy (PPV) in type 2 diabetic patients.

Methods: A retrospective study was conducted for PDR eyes undergoing PPV in type 2 diabetic patients. All patients were divided into three groups based on Chinese Ocular Fundus Diseases Society (COFDS) classification for PDR: Group A (primary vitreous hemorrhage), Group B (primary fibrovascular proliferation) and Group C (primary vitreous hemorrhage and/or fibrovascular proliferative combined with retinal detachment).

Evaluation of efficacy and safety of Qiangzhu-qinggan formula as an adjunctive therapy in adult patients with severe influenza: study protocol for a randomized parallel placebo-controlled double-blind multicenter trial.

Background: Influenza can fall into three categories according to severity: mild influenza, severe influenza, and critical influenza. Severe influenza can result in critical illness and sometimes death particularly in patients with comorbidities, advanced age, or pregnancy. Neuraminidase inhibitors (NAIs) are the only antiviral drugs in widespread use for influenza.

Efficacy of integrating short-course chemotherapy with Chinese herbs to treat multi-drug resistant pulmonary tuberculosis in China: a study protocol.

Background: Tuberculosis (TB) caused Mycobacterium tuberculosis (M.tb) is one of infectious disease that lead a large number of morbidity and mortality all over the world. Although no reliable evidence has been found, it is considered that combining chemotherapeutic drugs with Chinese herbs can significantly improves the cure rate and the clinical therapeutic effect.

Dexmedetomidine protects against degeneration of dopaminergic neurons and improves motor activity in Parkinson's disease mice model.

Parkinson's disease (PD) is the result of dopaminergic (DA) neuronal death in the substantianigra pars compacta (SNc). Current treatments for PD such as L-dopa are limited in effectiveness and fail to address the cause. Targeted anti-inflammatory therapies, particularly directed at nuclear factor kappa B (NF-κB) activity in alleviating degeneration of DA-neurons is of evolving interest.

Peripheral lymphocyte subset variation predicts prostate cancer carbon ion radiotherapy outcomes.

The immune system plays a complementary role in the cytotoxic activity of radiotherapy. Here, we examined changes in immune cell subsets after heavy ion therapy for prostate cancer. The lymphocyte counts were compared with acute radiotherapy-related toxicity, defined according to the Common Terminology Criteria for Adverse Events, and short-term local efficacy, defined based on prostate-specific antigen concentrations.

[The correlation between the level of serum VEGF and bFGF with metastasis and prognosis of osteosarcoma].

Aim: To investigate the correlation between the level of serum VEGF and bFGF with metastasis and re- currence of osteosarcoma.

Methods: 52 patients with osteosarcoma and 60 healthy people as control group were selected. The serum contents of VEGF and bFGF were determined with ELISA before and after operation.

[Preliminary clinical study on the posterior lumbar minimally invasive surgery assisted by 3D-Viewer system under a direct vision].

Objective: To study the methods and preliminary clinical efficacy of posterior lumbar minimally invasive surgery assisted by 3D-Viewer system under a direct vision and provide rationales for further clinical applications.

Methods: From September 2008 to September 2009, a total of 84 lumbar degenerative disease patients were enrolled and randomly divided into 2 groups (n = 42 each). One group was treated operatively by 3D-Viewer system under a direct vision while another treated with conventional operations.

[Metrx quadrant system in the surgery of lumbar spondylolisthesis: preliminary clinical application].

Objective: To evaluate the clinical efficacy and minimal invasiveness of quadrant posterior distraction system in the posterior lumbar spondylolisthesis (LS) surgery.

Methods: Sixty-one LS patients were randomly divided into two groups: quadrant posterior minimally invasive surgery system as invasive group (n = 30) and traditional open surgery as open group (n = 31). The clinical outcome of pain relief was assessed by the scoring systems of visual analogue scale (VAS) and Oswestry disability index (ODI) for low back pain.

[Prevention of dura adherence in spinal canal after microendoscopic discectomy by different methods: a clinical study of 165 cases].

Objective: To evaluate the effects of different methods in prevention of post-operational scar formation and dura adherence in the spinal canal after microendoscopic discectomy (MED).

Methods: 165 patients undergoing MED were randomly divided into 3 equal groups: Group A, with the yellow ligament dissected and with the space between vertebral laminae sprinkled with sodium hyaluronate before the closing of the incision; Group B, with the yellow ligament reserved; and Group C, with the yellow ligament reserved and with the space between vertebral laminae sprinkled with sodium hyaluronate before the closing of the incision. All the patients were followed up 2, 4, and 8 weeks, and 1 and 2 years after the operation.
