[Clinical observation of different intramedullary fixation methods for the treatment of intertrochanteric fracture].

Objective: To explore clinical efficacy of proximal femoral nail anti-rotation(PFNA),InterTan and proximal femoral bionic intramedullary nail (PFBN) in treating femoral intertrochanteric fracture.

Methods: Clinical data of 120 patients with intertrochanteric fracture who were underwent closed reduction intramedullary nail-internal fixation from January 2020 to January 2021 were retrospectively analyzed. According to methods of internal fixation,patients were divided into 3 groups.

A randomized, parallel control and multicenter clinical trial of evidence-based traditional Chinese medicine massage treatment VS External Diclofenac Diethylamine Emulgel for the treatment of knee osteoarthritis.

Background: Both massage and topically administered NSAIDs are safe and effective treatments for knee osteoarthritis (KOA); however, different massage technique sects in China caused assessment difficulties for the treatment of KOA. In order to standardize the massage techniques and procedures, we organized multi-disciplinary experts in China to acquire an evidence-based traditional Chinese medicine massage treatment of knee osteoarthritis. The purposes of this study will be to provide clinicians a complementary and alternative therapy for patients and to evaluate the efficacy and safety of evidence-based traditional Chinese medicine massage treatment of KOA compared to External Diclofenac Diethylamine Emulgel.

[Minimally invasive osteotomy and manual reduction for hallux valgus].

Objective: To explore clinical effects of minimally invasive osteotomy and manual reduction in treating hallux valgus.

Methods: From January 2018 to May 2019, 31 patients (42 feet) with hallux valgus were treated with minimally invasive osteotomy and manual reduction, including 3 males and 28 females aged from 18 to 76 years old with an average of (50.1± 4.

Nickel-catalyzed product-controllable amidation and imidation of sp C-H bonds in substituted toluenes with sulfonamides.

A nickel-catalyzed product-controllable imidation and amidation of sp C-H bonds in substituted toluenes with sulfonamides were developed. Based on the change of the reaction time and atmosphere from N to O, this reaction proceeded in high yields and excellent selectivity under different conditions. Mechanistic details were also described.

Nickel-Catalyzed Regioselective Cross-Dehydrogenative Coupling of Inactive C(sp(3))-H Bonds with Indole Derivatives.

A nickel-catalyzed regiosepecific C2- versus C3-oxidative cross-coupling reaction of indoles with 1,4-dioxane and other inactive C(sp(3))-H bonds is described. The divergent synthesis of C(sp(3))-C(sp(2)) bonds was achieved in satisfactory yields with di-tert-butyl peroxide (DTBP) as the oxidant, which provides an efficient strategy for the selective construction of cyclic ethers containing heteroaromatic core structures.

[Comparative study on effect and safty of treating on calcaneus fractures with manipulative reduction with percutaneous K-wire fixation].

Objective: To explore the clinical effects and safty of manipulative reduction with percutaneous poking K-wire fixation for the treatment of the calcaneus fractures and analyze the indication of the minimal invasion.

Methods: From December 2008 to December 2011,135 closed calcaneal fractures cases were divided randomly into poking group and plate group, treated respectively by percutaneous poking reduction and operative reduction. In poking group, there were 69 cases (82 feet) including 60 males and 9 females, with an average age of (43.

[Study on the correlation between syndrome differ classification of knee osteoarthritis and X-ray image].

Objective: To study the correlation between syndrome differ classification of knee osteoarthritis and X-ray image, so as to provide evidence for clinical diagnosis and treatment.

Methods: From Jun. 2007 to Dec.

[Study on the relationship between clinical syndromes and X-ray manifestation of knee osteoarthritis].

Objective: To study the relationship between clinical syndromes and X-ray manifestation of knee osteoarthritis (KOA), so as to provide evidence for clinical diagnosis and treatment.

Methods: Seventy-eight patients (108 knees) with KOA from out-patient clinic of orthopedic were collected, aged from 41 to 77, including 65 females (89 knees) and 13 males (19 knees). Questionnair investigation of Lequesne index was performed among all these patients and the Lequesne index was calculated.
