Objective To investigate the feasibility and effectiveness of the novel bone hook combined with finger-guided technique in the treatment of irreducible intertrochanteric femoral fractures in elderly. Methods Between January 2021 and August 2023, 23 elderly patients with irreducible intertrochanteric femoral fractures were treated with the novel bone hook combined with finger-guided technique. There were 10 males and 13 females; the age ranged from 68 to 93 years (mean, 76.2 years). The time from injury to operation ranged from 36 to 76 hours (mean, 51.2 hours). According to the classification standard proposed by TONG Dake et al in 2021, there were 10 cases of typeⅠA, 1 case of typeⅠB, 6 cases of type ⅡA, 4 cases of type ⅡB, and 2 cases of type ⅡC. The operation time, intraoperative blood loss, intraoperative fluoroscopy frequences, and quality of fracture reduction were recorded. The fracture healing time and occurrence of postoperative complications were observed during follow-up. At last follow-up, the Harris scoring system was used to evaluate the hip joint function. Results The operation time was 42-95 minutes (mean, 52.1 minutes). The intraoperative blood loss was 40-420 mL (mean, 126.5 mL). Intraoperative fluoroscopy was performed 14-34 times (mean, 20.7 times). According to the criteria proposed by Chang et al, the quality of fracture reduction was rated as good in 20 cases and acceptable in 3 cases. All patients were followed up 6-20 months (mean, 10.2 months). X-ray film showed that all fractures healed with the healing time of 3.0-5.5 months (mean, 4.0 months). At last follow-up, the Harris score of the hip joint ranged from 82 to 97 points (mean, 90.4 points). Among them, 14 cases were rated as excellent and 9 cases as good. No complication such as coxa vara, cutting of the cephalomedullary nail, nail withdrawal, or nail breakage occurred during follow-up. Conclusion The treatment of elderly patients with irreducible intertrochanteric femoral fractures by using the novel bone hook combined with finger-guided technique can achieve high-quality fracture reduction and fixation, and has a good effectiveness.
Objective To investigate the students’ satisfaction on teaching content, teaching staff, organizations etc. of the evidence-based medical postgraduate summer school, so as to provide references for further effective training. Methods A self-made questionnaire with cluster sampling was used to investigate the regular students who had participated in the whole course of the evidence-based medical postgraduate summer school, and the feedbacks were analyzed. Results The total number of the questionnaires was 112 and the number of the effective questionnaires was 101; the effective recovery rate was 90.2%. The students were from 32 universities and medical institutions involving 36 disciplines in 26 provinces. A total of 93.1% of the students were satisfied with the general training organization and management, but the satisfaction rates of the class environment and the time arrangement were only 51.5% and 58.4%, respectively. The satisfaction rates of the whole course setting and the teaching materials were 84.2% and 90.1%, respectively. The satisfaction rate of the teaching content of “the progress of the evidence-based medicine” was up to 93.0%. Over 93.1% of the students believed that the teachers were great in teaching skills, but only 73.3% of the students thought that the interaction between teachers and students was plenty. Conclusion This summer school has active students, a great effect and a high overall satisfaction rate. The summer school is beneficial to the cultivation of innovative postgraduates, construction of excellent teaching teams, development of evidence-based medicine discipline and building of The Network Center for Evidence-Based Medicine Education. The satisfaction rate of the summer school training can get promoted by increasing schooling investments, appropriately prolonging training time, setting different subjects in different semesters and enhancing the teaching interaction.
【摘要】 目的 了解科研志愿者參與科研活動的現狀及滿意度，為促進本科生科研能力培養提供決策建議。 方法 以參與四川大學華西臨床醫學院循證醫學中心及多學科綜合治療（MCQ）兩項科研志愿者活動的407名同學為調查研究對象，采用自制問卷表進行調查。對數據進行描述性分析和Logistic回歸分析。 結果 發放問卷407份，回收有效問卷351份，有效回收率86.24%。80.6%的受訪對象對目前參與科研活動現狀表示滿意。認為限制工作進展的主要因素是缺乏相關基礎知識和基本技能（占34.7%）以及缺乏時間（占31.6%）。21.1%的科研活動無固定的組織模式。96.2%的受訪對象表示有必要進行活動成果展示。是否有導師指導、是否有知識傳授和技能培訓以及對活動組織模式是否滿意是影響科研志愿者對科研活動滿意度的主要因素（P值分別為0.027、0.011和0.000）。 結論 志愿者參與科研活動的滿意度總體較高;滿意度受到多種因素影響。建立科研志愿者招募體系、完善科研能力培養層次、加強科研團隊組織建設、規范管理運作機制、嵌入科研課程并加強科研成果展示有助于提升本科生科研活動的參與率及滿意度，對醫學本科生科研能力培養具有積極作用。【Abstract】 Objective To study the current status and satisfactory degree of student volunteers’’ participation in scientific research, so as to provide suggestion for improving the scientific research capability of medical undergraduates. Methods Carried out a survey on 407 student volunteers from EBM (Evidence-Based Medicine) and MCQ (Matrix clinical quality) research program in West China Medical School, Sichuan University with self-designed questionnaires.The data was described and analyzed with logistic regression. Results A total of 351 (86.24%) valid questionnaires were retrieved among all the 407 questionnaires assigned.80.6% of the respondents were contented with the current situation of scientific volunteers’ program.34.7% of respondents thought that lack of basic knowledge and skill was the main factor that limited the progress of their research work.While for another 31.6% respondents, the main limited factor was lack of extracurricular time.21.1% of research activities were not operated in a standardized organizational mode.96.2% of the respondents emphasized on the necessity of exhibiting their works and achievements in public.“Tutor’s instructions”, “training on basic knowledge and skills” and “organizational mode” were the main factors which affect the satisfactory degree on scientific volunteer programs (P=0.027, 0.011, and 0.000, respectively) . Conclusion The satisfactory degree of students who participated in scientific volunteer programs is generally satisfying, however affected by various factors. Increase of participation rate in scientific research program can be attributed to factors such as establishment of a scientific volunteer recruitment system, improvement of students’ research capability, standard organizational modes, standard managing and operating mechanism, embed training lessons into courses
