Objective To detect the sperm apoptosis rate and level of reactive oxygen species (ROS) in seminal plasma and explore their correlation among infertile males. Methods Ninety-two inferitile males were divided into varicocele (VC) group (n=32), leukocytospermia group(n=30) and the other cause group (n=30), and another 24 in vitro fertilization sperm samples were sereved as controls. The routine sperm parameters including seminal pH, sperm viability and sperm density were examined by computer assisted sperm analysis, the sperm apoptosis rate was asseseed using Annexin V/PI staining, and the ROS level in seminal plasma was detected by TBA method. The differences in seminal parameters between three infertile groups and control group were compared, and the correlation of sperm apoptosis rate with level of ROS in seminal plasma was explored in each group. Results The sperm viability of three infertile groups was significantly lower than that of control group (P<0.01). The sperm apoptosis rates and levels of ROS in seminal plasma in VC group and leukocytospermia group were significantly higher than those in control group (P < 0.05 or P < 0.01). The sperm apoptosis rate was positively correlated with the level of ROS in seminal plasma in leukocytospermia group(r=0. 573, P < 0.05). Conclusion The increased sperm apoptosis rate and level of seminal plasma ROS may be related to the infertility of patients with VC and leukocytospermia. The increased level of seminal plasma ROS may be one of the causes of increased sperm apoptosis rate in patients with leukocytospermia.

Objective To report treatment of infectious bone and soft tissue defects caused by tibial shaft fracture of Gustilo type Ⅲ B using free flap and Ilizarov bone transport.Methods Nineteen patients who had suffered from infectious bone and soft tissue defects following tibial shaft fracture of Gustilo type Ⅲ11 B were treated from May 2010 to February 2015.They were 15 men and 4 women,aged from 21 to 58 years (average,45.3 years).Their course of disease ranged from 16 to 21 months,averaging 17.9 months.The area of their infectious defects ranged from 10 cm × 6 cm to 21 cm × 12 cm,and the length of their bone defects from 5 to 11 cm (average,7.4 cm).They were treated with debridement,simple external fixation to reconstruct bony support,coverage of wounds with free flap,and stuffing the dead space with antibiotic concrete beads,followed by Ilizarov bone transport and bone graft after control of infection to reconstruct the defective tibia and function of the affected limb.Results All the flaps survived.Necrosis occurred at the distal margin of one flap but responded to dressing.Pin tract infection occurred in 4 cases but also responded to dressing and antibiotic therapy.Autografts of iliac cancellous bone were implanted into the gliding and traction ends of the bone fragments one month after bone transport had come to rest.All the patients achieved direct bony union.The patients were followed up for an average of 25 months(range,from 19 to 36 months).No secondary fractures or angular deformity was observed.The total treatment time averaged 17.9 months,with no recurrence of infection.According to the Puno score system for functional evaluation at the last follow-up,7 cases were rated as excellent,6 as good and 6 as fair.Conclusion The infectious bone and soft tissue defects caused by tibial shaft fracture of Gustilo type Ⅲ B can be treated by free flap and Ilizarov bone transport,resulting in definitely positive outcomes.
