[A V-Y shaped flap with digital artery nerve at metacarpophalangeal joint was used to repair the defect of middle and distal phalanx].

Objective: To explore a surgical method for the reconstruction of volar soft tissue defect and sensory and vascular repair in middle and far phalangeal digits.

Methods: From January 2016 to January 2020, a total of 14 patients , 9 males and 5 females, ages ranging from 22 to 69 years old, and with volar soft tissue defects in the middle and distal digits 2 to 4, underwent surgical reconstruction using the V-Y shaped flap with digital artery and nerve at the metacarpophalangeal joint. The defect area was (2.

Application of the maximum threshold distances to reduce gene flow frequency in the coexistence between genetically modified (GM) and non-GM maize.

On the coexistence of genetically modified (GM) and non-GM maize, the isolation distance plays an important role in controlling the transgenic flow. In this study, maize gene flow model was used to quantify the MTD and MTD in the main maize-planting regions of China; those were the maximum threshold distance for the gene flow frequency equal to or lower than 1% and 0.1%.

Objective: To investigate the clinical effect of repairing soft tissue defect after hand wound using reverse island skin flap of upper carpal cutaneous branches of ulnar artery.

Methods: From June 2010 to November 2016, 12 patients with hand soft tissue defects were repaired by reverse island skin flap of upper carpal cutaneous branches of ulnar artery, including 9 males and 3 females with an average age of (35.2±9.

[Internal fixation with one-hole microplate for the treatment of collateral ligament injuries of the metacarpophalangeal joint of the thumb combined with fracture].

Objective: To study clinical effects of one-hole microplate internal fixation for the treatment of collateral ligament injuries of the metacarpophalangeal joint of the thumb combined with fracture.

Methods: Twenty-two patients (16 males, 6 females) with collateral ligament injuries of the metacarpophalangeal joint of the thumb combined fracture were treated with one-hole microplate internal fixation. The age of the patients ranged from 18 to 53 years old with a mean age of 28.

[Application of vacuum sealing drainage and cryopreservation technology in hand and foot skin replantation].

Objective: To summarize the clinical effect of avulsed skin replantation of hand and foot via vacuum sealing drainage (VSD) combing low temperature technique.

Methods: From March 2012 to October 2013,13 cases with avulsed skin replantation of hand foot using combined technique included 8 males and 5 females with an average age of 32 years old ranging from 18 to 62 years. The time from injury to hospital was 1 to 4 hours (2.

[Containing negative pressure drainage technology combined dermatoplasty of full thick skin graft to repair surgical donor site of hallux toe].

Objective: To evaluate the effectiveness of vacuum sealing drainage (VSD) combined with skin grafting to repair donor site for wrap around flap of hallux toe.

Methods: From Jan. 2009 to Apr.

[Diagnosis and treatment of the metacarpophalangeal joint locking caused by sesamoid turned-over dislocation of the thumb].

Objective: To introduce diagnosis and treatment of the metacarpophalangeal joint (MPJ) locking caused by sesamoid turned-over dislocation of the thumb.

Methods: Five cases with metacarpophalangeal joint locking were involved in the study, male 4 and female 1. The average age was 35 years old(ranging from 18 to 47 years).
