BACKGROUND:Distal radius C fractures belong to multiple fractures in the joint. Its treatment should recover various angles and joint surface continuity outside the joint. The recovery of palmar tilt angle, radial inclination angle and radial height is also very important for treating distal radius. OBJECTIVE:To study the changes in palmar tilt angle, radial inclination angle and radial height after type C fractures of the distal radius repaired with Acu-Loc(R)2 VDR bone plate system. METHODS:From May 2015 to March 2016, 11 cases of type C distal radial fractures were treated with Acu-Loc(R)2 VDR bone plate system. Preoperatively, the palmar tilt angle was-31° to-4° (-12.45° on average), and the radial inclination angle was 6° to 18° (11.18° on average), and the radial height was 1.92 mm to 8.68 mm (5.28 mm on average). X-ray films were observed at postoperative 4, 8 and 12 weeks and half a year in all patients. Palmar tilt angle, radial inclination angle and radial height were measured and observed using anteroposterior and lateral X-ray films during final follow-up. Wrist function was assessed with Gartland-Werley score. RESULTS AND CONCLUSION:(1) 11 patients were followed and the postoperative follow-up ranged from 7 months to 15 months. X-ray films showed that the union of fractures was achieved in 6-8 weeks (6.5 weeks on average). No infection or internal fixation failure occurred. The articular facets were smooth in 10 patients and a little poor was found in 1 case (<2 mm). (2) After operation, the palmar tilt angle was 8° to 15° (11.55° on average) (P<0.05);the radial inclination angle was 22° to 27° (23.18° on average) (P<0.05);the radial height was 8.01 mm to 13 mm (11.03 mm on average) (P<0.05). (3) The results were excellent in 8 cases, good in 2 cases, and poor in 1 cases according to Gartland-Werley wrist function assessment;the excellent and good rate was 91%. (4) Acu-Loc(R)2 VDR bone plate fixation can provide reliable fixation and effective support for type C distal radius fractures, which can recover the palmar tilt angle, the radial inclination angle and the radial height, so the Acu-Loc(R)2 VDR bone plate is an ideal method to treat type C fractures of the distal radius.

Primary mediastinal seminoma is a kind of germ cell malignancy outside the gonads, and it’s rarer with sarcoma component. hTis disease which has no special clinical manifestations and imaging characteristics is diffcult to identify with other mediastinal tumors and mediastinal type lung cancer. hTis paper reported a case of primary mediastinal seminoma with mediastinal sarcoma. hTrough the analysis of the diagnosis and treatment process in this patient, we will make a compre-hensive review of the disease.

Objective To explore the construction of a core competency framework and content for higher vocational speech-lan-guage-hearing rehabilitation technology programs based on World Health Organization rehabilitation competency framework(RCF). Methods Utilizing RCF and integrating the educational objectives for higher vocational speech-language-hearing reha-bilitation programs outlined by the Ministry of Education in 2022,as well as the technical documents from the In-ternational Association of Logopedics and Phoniatrics and the American Speech-Language-Hearing Association,this study analyzed the professional activities in speech-language-hearing rehabilitation technology to construct a competency framework based on RCF and give details in the specific content of each domain. Results The competency for speech-language-hearing rehabilitation technology encompassed seven domains:core val-ues,beliefs,practice,professionalism,learning and development,management and leadership,and research.Each domain was subdivided into specific competency elements and professional activities. Conclusion Establishing a higher vocational education system for speech-language-hearing rehabilitation technology based on RCF will help to set educational objectives,and construct curriculum systems,so that to cultivate practi-tioner who meet social needs and possess comprehensive professional skills and competencies.

Objective To analyze the core curricula framework of speech-language-hearing rehabilitation technology in vocational colleges,and formulate the course objectives,content and teaching methods.By constructing competency-orient-ed curricula,it is aimed to develop comprehensive competencies among students,and ensure they can meet di-verse service needs. Methods WHO rehabilitation competency framework(RCF)5+2 structure was adopted to systematically analyze the ob-jectives,content,instruction and evaluation approaches of eight core curricula in speech-language-hearing reha-bilitation technology at vocational colleges.By incorporating international standards from International Associa-tion of Logopedics and Phoniatrics and American Speech-Language-Hearing Association,the core curricula framework was designed to meet the educational needs in China.A contextualized teaching method that empha-sizes the integration of theory and practice was employed to ensure the comprehensive development of students'knowledge,skills,and professional competencies. Results A curricula framework that integrating theory with practice was established using RCF,covering various aspects from assessment to rehabilitation interventions.The content of eight core curricula and the corresponding rehabil-itation competencies were systematically analyzed using RCF,thereby systematic course objectives,content and teaching methods were constructed.This curricula framework encompassed core knowledge,skills and competen-cies in rehabilitation sciences,in order to ensure that students were equipped to handle complex service situations. Conclusion It is valuable to develop the competency-based core curricula for speech-language-hearing rehabilitation technology using RCF,for advancing competency-oriented vocational education.These curricula not only align with the current demand for highly skilled professionals in the rehabilitation industry,but also lay a foundation for students'continuous professional development.By emphasizing practical skills and interdisciplinary collabo-ration,the courses enable students to effectively function in dynamic rehabilitation environments,meeting di-verse rehabilitation needs.

Objective:To establish an animal model of trichloroethylene (TCE) -induced liver cancer following chronic exposure and to understand the changes in SET expression and histone acetylation, potentially serving as a molecular mechanism for TCE-induced hepatocarcinogenesis.Methods:B6C3 mice at 6 weeks were treated with TCE at a series of doses (500, 1000 and 2000 mg/kg) by gastric gavage, with corn oil used as the negative control and carbon tetrachloride (CCl 4) as the positive control. The serum and liver were sampled for the determination of biochemical indexes and pathological examination after 56 weeks of chemical exposure. Western blot was used to determine the levels of SET, H2AK9ac and HDAC1 expression. Results:The overall survival rate of the mice in various groups was 90.4% (141/156) , with no statistical difference between groups ( P>0.05) . Compared with the negative control, the organ coefficient for the liver in the high dose TCE group and the positive control group were significantly increased ( P<0.05) . The levels of ALT, AST, LDH and BUN in the all the three TCE groups and the positive control were significantly higher than those in the negative control ( P<0.01) . CREA levels in the 1000 and 2000 mg/kg TCE groups were significantly higher than those in the negative control ( P<0.05) . Statistical increases in the incidence of hepatocellular carcinoma and the activities of ALT and AST in various doses of TCE-exposed mice as compared with the control were observed ( P<0.01) , in a dose-dependent manner. In the 1000 and 2000 mg/kg of TCE treated mice, levels of SET and H2AK9ac were increased ( P<0.05) , while HDAC1 was decreased ( P<0.05) , Compared to the tissue adjacent to liver cancer, in the 1000 and 2000 mg/kg TCE groups, the levels of SET were increased ( P<0.05) , while HDAC1 was decreased ( P<0.05) , and H2AK9ac increased in the 2000 mg/kg group. Conclusion:The hepatocellular carcinoma mouse model induced by chronic exposure to trichloroethylene was successfully established, with enhanced SET protein expression and H2AK9ac in the hepatic tissue.
