The aim of this study was to improve the quality of semen samples by using a novel double-tube (DT) method. The DT method was developed to select sperm and compared with traditional swim-up (SU) technique for 31 semen samples. Sperm DNA integrity were tested with TUNEL and SCSA.

Methods: Exposure of the scrotum of 25 healthy male volunteers locally at 40-43°C SHS belt warming 40 min each day for successive 2 d per week. The course of SHS was continuously 3 months.
Purpose: To observe changes in semen parameters, sperm DNA integrity, chromatin condensation and cysteinyl aspartate-spicific proteinases (Caspase-3) in adult healthy men after scrotal heat stress (SHS).
Methods: The scrotums of 19 healthy male volunteers were exposed to the condition of 40-43 °C SHS belt warming 40 min each day for successive 2 days per week. The course of SHS was continuously 3 months.
Background: Although traumatic brain injury can lead to opening the blood-brain barrier and leaking of blood substances (including water) into brain tissue, few studies of brain antigens leaking into the blood and the pathways have been reported. Brain antigens result in damage to brain tissues by stimulating the immune system to produce anti-brain antibodies, but no treatment has been reported to reduce the production of anti-brain antibodies and protect the brain tissue. The aim of the study is to confirm the relationship between immune injury and arachnoid granulations following traumatic brain injury, and provide some new methods to inhibit the immune injury.

Methods: Perilesional extracellular Gly and cerebral blood flow (CBF) in 53 patients with STBI were consecutively monitored. Simultaneously, the intracranial pressure (ICP) and cerebral perfusion pressure (CCP) were monitored.
Objective: To study the effect of mild hypothermia on glucose metabolism and glycerol of brain tissue in patients with severe traumatic brain injury (STBI) using clinical microdialysis.
Methods: Thirty-one patients with STBI(GCS less than or equal to 8) were randomly divided into hypothermic group(Group A) and control group(Group B). Microdialysis catheters were inserted into the cerebral cortex of perilesional and normal brain tissue.

Objective: To study the changes of extracellular glucose (Glu), lactate (Lac), and the ratio of lactate/pyruvate (L/P) in patients with traumatic brain injury under different body temperatures.
Methods: Catheters for microdialysis were punctured into the penumbra zone of injured brain tissue (INJ), relatively normal brain tissue (NOR), and abdominal subcutaneous tissue (ABD) respectively in 51 patients to collect the fluid. The perfusion rate was 0.
