[Treatment of old calcaneal fractures with calcaneus V-shape osteotomy for the subtalar joint preservation].

Objective: To observe the clinical effect of calcaneus V-shape osteotomy for the subtalar joint preservation in the treatment of old calcaneal fractures.

Methods: A retrospective study was conducted on 18 patients (18 feet) with old calcaneal fractures treated by calcaneus V-shape osteotomy from March 2014 to November 2017. Included 13 males and 5 females, aged from 23 to 48 years old with an average of (34.

[Four kinds of operative methods for subtalar arthrodesis in treating old calcaneal fracture].

Objective: To explore clinical efficacy of four surgical methods for subtalar joint fusion and internal fixation in treating old calcaneal fractures.

Methods: From March 2014 to November 2017, 25 patients (26 feet) with old calcaneal fractures treated with four surgical methods of subtalar arthrodesis were retrospectively analyzed, including subtalar joint fusion in situ for 2 patients (2 feet), subtalar articular strut bone graft fusion for 6 patients (6 feet), subtalar joint fusion with calcaneus V-shaped osteotomy for 6 patients(6 feet), and subtalar bone graft fusion with calcaneus cuneiform osteotomy for 11 patients (11 feet). They aged from 23 to 70 years old with an average of (36.

[Bone and soft tissue combined with surgery for the treatment soft flatfoot combined with painful navicular bone].

Objective: To explore short-term clinical effects of bone and soft tissue combined with surgery for the treatment of soft flatfoot accompanied with painful navicular bone.

Methods: From May 2015 to August 2017, 16 patients (16 feet) with navicular bone soft flatfoot accompanied with painful navicular bone were treated with bone and soft tissues operation (gastrocnemius release, medial displacement calcaneal osteotomy, and excision of accessory navicular with reconstruction of posterior tibial tendon). Among them, there were 9 males (9 feet) and 7 females (7 feet), aged from 22 to 48 years old with an average of (32.

Capsaicin-loaded folic acid-conjugated lipid nanoparticles for enhanced therapeutic efficacy in ovarian cancers.

In this study, folic acid-conjugated lipid nanoparticles were successfully prepared to enhance the active targeting of capsaicin (CAP) in ovarian cancers. The particles were nanosized and exhibited a controlled release of drug in the physiological conditions. The folic acid (FA)-conjugated system exhibited a remarkably higher uptake of nanoparticles in the cancer cells compared to that of non-targeted system.
