Fabrication of Poly (Trans-3-(3-Pyridyl)Acrylic Acid)/Multi-Walled Carbon Nanotubes Membrane for Electrochemically Simultaneously Detecting Catechol and Hydroquinone.

Herein, conductive polymer membrane with excellent performance was successfully fabricated by integrating carboxylated multi-walled carbon nanotubes (MWCNTs) and poly (trans-3-(3-pyridyl) acrylic acid) (PPAA) film. The drop-casting method was employed to coated MWCNTs on the glassy carbon electrode (GCE) surface, and PPAA was then electropolymerized onto the surface of the MWCNTs/GCE in order to form PPAA-MWCNTs membrane. This enables the verification of the excellent performances of proposed membrane by electrochemically determining catechol (CC) and hydroquinone (HQ) as the model.

Analysis of the Effect of Antibiotic Bone Cement in the Treatment of Diabetic Foot Ulcer through Tibia Transverse Transport.

Objective: To explore the efficacy of antibiotic bone cement (ABC) combined with the modified tibial transverse transport (mTTT) on the treatment of severe diabetic foot with infection.

Methods: A retrospective cohort study was conducted of 243 patients with TEXAS grade 3/4 stage D diabetic foot ulcers from December 2016 to December 2019. A total of 115 patients treated with mTTT were classified as the mTTT group (78 male and 37 female, mean age: 70.

[Modified transverse tibial bone transplantation and microcirculation reconstruction for the treatment of end-stage diabetic foot].

Objective: To explore clinical effect of modified transverse tibial bone transfer microcirculation reconstruction in treating end-stage diabetic foot.

Methods: From August 2016 to June 2018, 87 patients with diabetic foot treated with modified tibial transverse bone removal and microcirculation reconstruction, inclduing 54 males and 33 females;aged from 39 to 95 years old with an average of (68.9±11.
