Objective:To evaluate the curative efficacy of a buttress plate combined with Kirschner wires for treatment of Regan-Morrey type Ⅱ coronoid fracture after elbow terrible triad injury.Methods:A retrospective study was conducted of the 20 patients who had been surgically treated for Regan-Morrey type Ⅱ coronoid fracture after elbow terrible triad injury from August 2014 to August 2018 at Department of Pelvic Trauma, Henan Luoyang Orthopedic-Traumatological Hospital. They were 12 men and 8 women, aged from 18 to 60 years (average, 39 years), with 6 left and 14 right sides affected. All the coronoid fractures were fixated with Kirschner wires plus a buttress plate through the anterior approach, the radial head and lateral collateral ligaments (LCL) were repaired through the posterolateral approach, and the medial collateral ligament (MCL) was repaired or fixated with a hinged external fixator if necessary. The curative efficacy was evaluated at the last follow-up by range of motion (ROM) of the elbow, Mayo elbow performance score (MEPS), American Shoulder and Elbow Surgeons Scale (ASES) and radiographs of the elbow. Complications were also recorded.Results:The mean follow-up time was 18 months (from 12 to 24 months) and the mean healing time 5 months. At the last follow-up, ROM in flexion and extension of the affected elbow joint averaged 132.5°, ROM in elbow pronation-supination 150°, MEPS 88, and ASES 87. No subluxation or dislocation occurred after elbow surgery. The fracture of coronoid process was slightly displaced in one case but eventually healed without affecting any elbow function; fat liquefaction occurred around the posterolateral incision in 2 cases but healed after debridement; traumatic arthritic changes occurred in 5 patients but no significant dysfunction of the elbow was observed.Conclusion:A buttress plate combined with Kirschner wires can lead to fine curative efficacy for Regan-Morrey type Ⅱ coronoid fracture after elbow terrible triad injury.

Objective To investigate the effects of danhong injection on the apoptosis of SMMC-7721 heptoma cells.Methods The hepatocellular carcinoma cell line SMMC-7721 was incubated with different concentrations(0,2,4,8 μL·mL-1) of danhong injection, and cell morphology was studied under the microscope. The apoptosis index was detected by flow cytometry at 0,6,12,24 h after cultured with 2 μL·mL-1danhong injection. Cell proliferation was measured by MTT assay;Gene expressions of p53,Bax and Bcl-2 were detected by RT-PCR at different drug concentrations.

Objective To investigate the epidemiological features of 937 patients wounded in China Wenchuan earthquake. Methods An analysis was done on 937 patients treated in the city of Deyang in aspects fo their gender,age,injury causes,wound sites,complications and misdiagnosis.Results There were more wounded females than males,with ratio of male to female of 1:1.12.The main injury causes were crush injury and falling injury.The most frequent injury sites include head,chest,ankle and foot,tibia and fibula,spine and hip.The rate of misdiagnosis was as high as 15.5%,mainly brain injuries and chest iniuries. Conclusion The main causes are crush iniury and falling in-jury.Lower limb fractures account for the most.While close brain and thoracic injuries are likely to be misdiagnosed.

Objective To investigate the significance of albumin-bilirubin (ALBI) score in predicting prognosis of hepatocellular carcinoma (HCC).Methods The clinical data of 644 HCC patients were retrospectively analyzed from May 2010 to May 2013 in the First People's Hospital of Changde City and the Affiliated Tumor Hospital of Guangxi Medical University.Peripheral blood test results were used to calculate ALBI score,and ALBI score was categorized into the following 3 groups:grade 1,grade 2,grade 3.Overall survival(OS) and disease free survival(DFS) were evaluated by the Kaplan-Meier method.And independent prognostic predictors were determined by the Cox proportional hazard model.Results Multivariate analysis showed that ALBI grade 2 was an independent risk factor for OS(P＜0.05).The ALBI grade stratified patients into at least two distinct overall survival cohorts (P＜0.05),whereas the CP grade did not.The ALBI grade also classified patients with CP grade A patients into two distinct overall survival cohorts (P＜0.05).In the subgroup analysis,the ALBI grade seemed to be an independent factor in terms of Barcelona Clinical Liver Cancer staging system(BCLC) 0-C.Conclusion For patients with HCC who underwent R0 resection,the ALBI grade is a good predictor of OS in HCC patients,and the above conclusions is true in patients with BCLC stage 0-C.

Objective:To investigate the efficacy of a minimally invasive three-window incision and internal fixation with a novel anatomical locking plate in the treatment of calcaneal fractures.Methods:A retrospective analysis was performed of the 46 patients with calcaneal fracture (Sanders typeⅡ and Ⅲ) who had been admitted to Department of Orthopedics, Luoyang Orthopaedic Hospital of Henan Province from February 2015 to May 2017. They were 22 males and 24 females, aged from 19 to 59 years (average, 39.0 years) and with 16 left and 30 right sides affected. They were all treated with a minimally invasive three-window incision and internal fixation with a novel anatomic locking plate. Their B?hler and Gissane angles, and height, width and length of the calcaneus were compared between preoperation, immediate postoperation and the last follow-up. Their ankle-hindfoot functions were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring scale at the last follow-up; their complications were recorded.Results:All the 46 patients were followed up immediately after operation and for 14 to 18 months (mean, 16 months). All the fractures achieved bony union after an average of 3 months (from 2 to 4 months). At immediate postoperation and at the last follow-up, their calcaneal B?hler angles (34.20°±3.62° and 34.05°±3.65°) and Gissane angles (131.45°±6.04° and 131.25°±5.88°), and calcaneal heights [(41.05±2.76) mm and (40.90±2.86) mm], widths [(25.65±1.53) mm and (25.55±1.64) mm] and lengths [(76.82±1.70) mm and (76.73±1.78) mm] were significantly improved compared with the preoperative values [10.55°±7.51°, 95.32°±12.16°, (26.10±4.54) mm, (37.71±3.42) mm and (65.91±2.10) mm] ( P<0.05). There were no significant differences in the above indexes between immediate postoperation and the last follow-up ( P>0.05). According to AOFAS ankle-hindfoot scores at the last follow-up, the efficacy was evaluated as excellent in 28 cases, as good in 12 cases and as fair in 6 cases, yielding an excellent and good rate of 87.0%. No incision infection occurred after operation. Conclusion:In the treatment of calcaneal fractures of Sanders type Ⅱ and Ⅲ, the minimally invasive three-window incision and internal fixation with the novel calcaneal anatomical locking plate can achieve satisfactory reduction and rigid fixation, effectively reducing postoperative incision complications.
