Efficacy of antifibrinolytic agents on surgical bleeding and transfusion requirements in spine surgery: a meta-analysis.

Purpose: Spine surgery is usually associated with large amount of blood loss and blood transfusion. Excessive blood loss may cause hypotension, inadequate oxygenation of organs, necessitate allogeneic blood transfusion, and spinal epidural hematoma formation. Aprotinin, TXA, and EACA are antifibrinolytics currently offered as prophylactic agents to reduce surgery-associated blood loss.

Expansion Open-door Laminoplasty With Foraminotomy Versus Anterior Cervical Discectomy and Fusion for Coexisting Multilevel Cervical Myelopathy and Unilateral Radiculopathy.

Study Design: This was a clinical prospective study.

Objective: To assess whether clinical and radiologic outcomes differ between expansion open-door laminoplasty with foraminotomy (EOLF) and anterior cervical discectomy and fusion (ACDF) in the treatment of coexisting multilevel cervical myelopathy and unilateral radiculopathy (CMUR).

Summary Of Background Data: No reports to date have compared clinical outcomes between anterior and posterior decompression for CMUR.

[The analysis of prognostic factors in patients with thoracic ossification of the ligamentum flavum and thoracic ossification of posterior longitudinal ligament by posterior decompression].

Objective: To investigate the prognostic factors for patients with thoracic ossification of the ligamentum flavum (OLF) and thoracic ossification of posterior longitudinal ligament (OPLL).

Methods: Clinical information of 83 patients suffering from thoracic OLF and OPLL was reviewed retrospectively from January 2006 to June 2010. The related factors such as gender, age, preoperative and postoperative Japanese Orthopedic Association (JOA) score, pathological segment, type of thoracic OPLL, degree of thoracic kyphosis, anteroposterior diameter of OPLL, range of circumferential decompression, cerebrospinal fluid leakage or not and dysfunction or not and carotid lumbar disorders or not were analyzed by Chi-square and Logistic regression.

[Distribution patterns of PAHs in soils from coking plant and the particle-size cut points of soil washing].

Soil particle size distribution and contaminants distribution patterns in different soil size fractions are the basis of soil treatability using soil washing method. Soil particle-size cut points are important parameters of soil washing process. According to ex situ soil washing technology, soil samples were collected in a former coking plant.

[Bone turnover markers in the detection of bone metastases in primary lung cancer].

Objective: To study which markers can be applied to monitor the presence of the bone metastases in primary lung cancer without bone lesion during the follow-up period.

Methods: Based on the criteria for inclusion, we screened and selected 10 cases of lung cancer with bone metastases, 10 cases of lung cancer without bone metastases and 10 healthy subjects. Then we measured their serum bone alkaline phosphatases (bALP) by chemiluminescence immunoassay, their serum beta-carboxyterminal telopeptide of type I collagen (sCTX) and their serum N-terminal midfragment osteoclacin (N-MID) by electro-chemiluminescence immunoassay, and their serum total alkaline phosphatases (tALP) by flurorescence enzyme immunoassay.
