[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.

Large mode area microstructured fiber supporting 56 super-OAM modes.

In this paper, a kind of super-mode orbital angular momentum microstructured fiber (SM-OAM-MSF) is proposed. By introducing 20 Ge-doped equiangular cylindrical inclusions in the ring-core region, mode coupling mechanism is employed in the formation of super-OAM (SOAM) modes. Specifically, the double degenerated out-of-phase SMs are first generated by the coupling of individual core mode, then the quadruple degenerated SOAM modes are formed by combining two components of the out-of-phase SMs with a phase difference of ±π/2.

[Supercontinuum Generation in Tapered Microstructure Fibers with Different Taper Length by Using Femtosecond Laser].

Tapered microstructure fibers with different taper lengths and waist diameters are pumped with femtosecond laser for supercontinuum generation. With “fast and cold tapered method”, home made microstructure fiber with air-hole pitch Λ=6.53 μm and normalized air-hole diameter d/Λ=0.

[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.

[Research progress in the treatment of calcaneal fractures].

Calcaneal fracture is a kind of common injury of foot. Calcaneal fracture could be treated with conservative therapy, open reduction and internal fixation (ORIF), minimal invasive poking reduction and Kirschner wire fixation, arthrodesis or external fixation and other treatment methods. Open reduction and internal fixation as the main treatment method of calcaneus fracture, especially for intra-articular calcaneal fractures, as Sanders type II and III fractures, could gain satisfactory effect.

[Case-control study on bone setting manipulation for the treatment of over degree II supination-eversion fractures of ankle joint].

Objective: To explore therapeutic effects of bone setting manipulation for the treatment of over degree II supination-eversion fractures of ankle,and analyze manipulative reduction mechanism.

Methods: From 2005 to 2008, 95 patients with over degree II supination-eversion fractures of ankle were treated respectively by manipulation and operation. There were 43 cases [11 males and 32 females with an average age of (44.

[Comparison of the therapeutical effectiveness between paper splint adduction fixation and plaster abduction fixation in Bennett fracture].

Objective: To study and compare the difference on the therapeutical effectiveness between paper splint adduction fixation and plaster abduction fixation in Bennett fracture.

Methods: In the study, seventy outpatient were selected from October 2005 to April 2007, and devided into two groups randomly involving experiment group (35 cases with paper splint adduction fixation) and control group (35 cases with plaster abduction fixation). After the fracture clinical healed and removed fixation, the patients had been followed up 6 months.

[Effect of zhenggu powder ([Chinese characters: see text]) on the inflammatory cell factor of soft tissue in experimental acute injury].

Objective: To probe the recovery mechanism of Zhenggu powder (ZGP) on acute soft tissue injury in cell levels.

Methods: Forty rabbits which established animal model of acute soft tissue injury with hammer hitting,were divided randomly into normal group (A), model group (B), vaseline group (C)and ZGP group (D). Injured part was applied external drug daily after model was made.
