Article Synopsis
  • The endangered plant species, endemic to China, was rediscovered in 2009 after being rarely collected since its initial description in 1902, raising important questions about its historical and future responses to climate change.
  • Geographic data was gathered and analyzed using a maximum entropy model (MaxEnt) to simulate potential distribution changes based on climate scenarios, indicating that temperature and precipitation patterns significantly influence its habitat suitability.
  • Findings suggest that Sichuan and Shaanxi may become stable areas for the species in the future, with recommended conservation strategies such as protected areas and public awareness initiatives to aid in its preservation.

Objective: To explore the best entry point and trajectory of anterior cervical screw in the cervical screw by radiological studies, and provide reference for clincal application.

Methods: From January 2008 to December 2010,50 patients were scanned by cervical CT and confirmed no obvious defect of lower cervical spine. Of them, 27 cases were males and 23 were females, ranged the age from 38 to 83 years ( mean 58.

Objective: To investigate the clinical results of distal tibia fractures accompanying with anterior soft tissue injury by posteromedial approach.

Methods: From August 2008 to August 2010,31 patients (21 males and 10 females, ranged in age from 24 to 68 years with an average of 46 years) with distal tibia fractures accompanying with anterior soft tissue injury were treated with open reduction and internal fixation through posteromedial approach. Of the 31 cases, 14 cases were open fractures (including 5 cases Gustilo-Anderson type I, 5 type II, 2 type III A, and 2 type III B) and 17 cases were closed fractures (including 3 cases Tcherne-Oestern type I, 12 type II, 2 type III).

Objective: To investigate therapeutic effects of vacuum sealing drainage (VSD) in the treatment of soft tissue defect combined with tendon and bone exposure.

Methods: From October 2007 to February 2011, 397 patients (412 feet) with open ankle fracture and dislocation combined with soft tissue defected were treated by VSD. There were 301 males and 96 females with an average age of 36 years (ranging age from 20 to 73 years).

Objective: To explore the clinical efficacy of delayed open reduction and internal fixation with minimally invasive percutaneous locking compression plate for the treatment of type II and III Pilon fractures.

Methods: From January 2007 to September 2009, 32 patients with type II and III Pilon fractures were treated with open reduction and anatomic plate fixation (AP group) and minimally invasive percutaneous locking compression plate osteosynthesis (LCP group). There were 11 males and 6 females in AP group, with an average age of (37.

Objective: To investigate the clinical results of the proximal femoral nail antirotation (PFNA) system in the treatment of unstable intertrochanteric femoral fractures.

Methods: From September 2006 to September 2009, 90 patients (40 males and 50 females, ranged in age from 64 to 95 years with an average of 73.2 years with unstable intertrochanteric femoral fractures were surgically treated with PFNA.

Article Synopsis
  • The study aims to evaluate the feasibility and technical specifics of using posterior transarticular screws for fixing the thoracic spine in cadaveric specimens.
  • Researchers dissected 20 thoracic cadaveric spines and measured screw trajectory using CT scans after implantation, noting angles and lengths.
  • The results showed successful placement of screws with slight angle variations between vertebrae and significant differences in trajectory lengths, indicating that this method is a viable alternative to standard pedicle screw fixation in thoracic stabilization.

Objective: To study the two-axis parallel method in bone lengthening.

Methods: Among 54 patients (male 28, female 26, mean age 22) who performed tibial lengthening by metaphyseal osteotomy using two-axis parallel method, 26 patients were poliomyelitis sequelae, 13 patients were inequality in limb length after trauma, 4 patients were achondroplasia, 6 patients were genetic short stature, 1 patient was maculatum disease complicated with leg length discrepancy, 4 patients were pituitary dwarfism.

Results: All the patients were followed up and the duration ranged from 18 months to 45 months, with an average of 24.
