Objectives: To evaluate the incidence and risk factors of postoperative pneumonia (POP) in geriatric patients with a hip fracture after surgery, to design a predictive nomogram, and to validate the accuracy of the nomogram.

Design: Retrospective study.

Setting: A tertiary hospital affiliated to a medical university.

Objective: To investigate the related risk factors and predictive nomogram of postoperative hypoxaemia in elderly patients with femoral neck fractures.

Methods: This study included patients aged ≥65 years who underwent surgical treatment of acute femoral neck fractures. Univariate and multivariate logistic analyses were performed to determine the incidence of and risk factors for postoperative hypoxaemia.

To evaluate the risk factors for the development of postoperative delirium and design a predictive nomogram for the prevention of delirium in elderly patients with a hip fracture, we retrospectively studied 825 patients who sustained a femoral neck fracture from January 2005 to December 2015. Independent risk factors for developing delirium within 6 months of surgery were identified using multivariable logistic regression analyses. A predictive nomogram model was built based on the results, and the discrimination and calibration were determined by C-index and calibration plot.

Background: Traditional incision repair and minimally invasive repair for acute Achilles tendon repair have limitations. This study aimed to present our series of 23 patients with acute Achilles tendon rupture that was repaired using two small incisions to assist the anchor repair of the tear and a new "circuit" suture technique.

Methods: This was a retrospective study of 23 patients with acute Achilles tendon rupture treated with the new technique at Changhai Hospital between January 2015 and December 2016 and followed up for 14-33 months.

Objective: To investigate the efficacy and complications of manual reduction and external fixation for the treatment of scaphoid fractures and perilunate dislocations.

Methods: From January 2009 to January 2013, 43 patients suffered from scaphoid fractures and perilunate dislocations were retrospective analyzed. Among them, 17 cases were treated with manipulative reduction and plaster external fixation as conservation group including 10 males and 7 females, the other 26 cases were treated with application of surgical as operation group including 15 males and 11 females.

Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. However, the underlying mechanism of osteosarcoma carcinogenesis and progression remains unknown. In the present study, we evaluated the expression profile of miRNAs in osteosarcoma tissues and the adjacent normal tissues.

We aim to investigate the effect of miR-106a-5p on the proliferation, migration, and invasion of osteosarcoma (OS) cells by targeting high-mobility group AT-hook 2 (HMGA2). Real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) was used for detecting the expressions of miR-106-5p and HMGA2 in 137 OS and adjacent normal bone tissues. Immunohistochemistry was applied for the HMGA2 protein expression detection.

Diverse functions of microRNAs have been investigated in tumorigenesis in osteosarcoma (OS), involving the regulation of proliferation, invasion, migration, apoptosis and drug resistance. MiR-367 was found to be an oncogene and increased in OS. However, the function of miR-367 in drug resistance in OS cells is still unknown.

Background: The results of peripheral nerve repair, especially for high-level peripheral nerve injuries, have been unsatisfactory. The method of side-to-side neurorrhaphy was developed in our laboratory from 1994 to 2002. This method involves suturing the injured nerve to a nearby donor nerve in a side-to-side manner.

Objective: To investigate the efficacy of the locking internal fixator (LIF), which includes the locking compression plate (LCP) and the less invasive stable system (LISS), in the proximal and distal tibial fractures.

Methods: We did a retrospective study on a total of 98 patients with either proximal or distal tibial fractures from January 2003 to January 2007, who had received the operation with LIF by the minimally invasive plate osteosynthesis (MIPO) technique. The data consisted of 43 proximal tibial fractures (type AO41C3) and 55 distal tibial fractures (type AO43C3).
