Objective:To establish the first Mini-Formative Evaluation of Radiation Oncology (Mini-FERO) scale in China and evaluate its preliminary application value in the standardized training for radiation oncology resident physicians.Methods:Based on the educational curriculum and examination requirements for the standardized training for radiation oncology resident physicians, as well as the standardized Mini-Clinical Evaluation Exercise (Mini-CEX) scale commonly used in clinical practice, the Mini-Formative Evaluation of Radiation Oncology (Mini-FERO) scale was developed to facilitate the standardized training for resident physicians in the field of radiation oncology. In this prospective study, a randomization method using a random number table was employed to select a cohort of 26 resident physicians who completed their rotations in Department of Radiation Oncology at the Cancer Hospital, Chinese Academy of Medical Sciences from March 1, 2021 to December 31, 2021. The Mini-FERO scale was administered in the initial, middle, and final stages during the rotation period. The differences in evaluation scores before and after the assessments were analyzed by paired t-test. Furthermore, participating resident physicians and supervising teachers provided satisfaction ratings, and a comprehensive evaluation of the Mini-FERO scale was conducted. Results:The average scores of the three examinations of 26 resident physicians demonstrated a successive improvement, with individual performance in each assessed category also showing progressive enhancement. The second evaluation exhibited a more pronounced score increase compared to the first evaluation, with a mean improvement of (1.43±1.02) points ( t=7.13, P<0.001); while the third evaluation had a mean improvement of (0.41±0.50) points ( t=4.07, P<0.001) compaired to the second evaluation, with a mean difference of (1.02±1.15) points between the two ( t=4.53, P<0.001). The average time required for the assessments was (34.31±24.46) min. Overall satisfaction ratings from the evaluated resident physicians for the Mini-FERO scale were (8.42±0.85) points, and supervising teachers reported an overall satisfaction rating of (8.45±0.85) points. The satisfaction rate was 96% (25/26). Conclusions:In this study, the Mini-FERO scale was successfully developed and validated in the context of clinical teaching practice for radiation oncology resident physicians. The Mini-FERO scale is proven to be a feasible tool for assessing the gradual improvement of resident physicians throughout their learning process in the field of radiation oncology. Importantly, it offers the advantages of short assessment time, thereby avoiding additional burden on supervising teachers. The adoption of the Mini-FERO scale addresses current limitations of lacking of formative evaluation in the standardized training for radiation oncology resident physicians.

Objective:To identify the risk factors of non-sentinel lymph node (nSLN) metastasis in breast cancer patients with 1~2 positive axillary sentinel lymph node (SLN) and construct an accurate prediction model.Methods:Retrospective chart review was performed in 917 breast cancer patients who underwent surgery treatment between 2002 and 2017 and pathologically confirmed 1-2 positive SLNs. According to the date of surgery, patients were divided into training group (497 cases) and validation group (420 cases). A nomogram was built to predict nSLN metastasis and the accuracy of the model was validated.Results:Among the 917 patients, 251 (27.4%) had nSLN metastasis. Univariate analysis showed tumor grade, lymphovascular invasion (LVI), extra-capsular extension (ECE), the number of positive and negative SLN and macro-metastasis of SLN were associated with nSLN metastasis (all P<0.05). Multivariate Logistic regression analysis showed the numbers of positive SLN, negative SLN and macro-metastasis of SLN were independent predictors of nSLN metastasis (all P<0.05). A nomogram was constructed based on the 6 factors. The area under the receiver operating characteristic curve was 0.718 for the training group and 0.742 for the validation group. Conclusion:We have developed a nomogram that uses 6 risk factors commonly available to accurately estimate the likelihood of nSLN metastasis for individual patient, which might be helpful for radiation oncologists to make a decision on regional nodal irradiation.

Objective: To summarize the technical points and clinical efficacy of pedicle subtraction osteotomy (PSO) in tunneling and to explore the related complications of this technique. Methods: A total of 67 cases of old vertebral fractures of the thoracolumbar region from June 2012 to June 2017 were collected. According to the inclusion and exclusion criteria, a total of 41 cases were included in the study. There were 19 males and 22 females; aged 37-67 years, mean 60.1±12.7 years; 15 cases of non-surgical treatment after trauma, 13 cases of failure after surgery and 13 cases of osteoporosis. Injury segment: 9 cases of T11, 22 cases of T12, 8 cases of L1, 2 cases of LS. Preoperative patients were diagnosed by X-ray, CT plain and 3D reconstruction combined with MRI. There were 23 cases of intractable back pain, 16 cases of lower extremity root pain, and 2 cases of intermittent claudication. Patients were divided into the traditional PSO treatment group (21 cases) and modified PSO treatment group (20 persons) according to the random number method. The traditional group were treated with the "egg shell" technique, and the improved group were treated with tunnel forming technology. The procedure was divided into four steps: exposure (step 1), nail placement and resection of the posterior column complex (step 2), vertebral osteotomy (step 3), orthopedics and bone grafting (step 4). The operation time, bleeding volume and complications of each step were compared between the two groups. The clinical efficacy was evaluated using the visual analogue scale (VAS) score and the Oswestry disability index (ODI). The X-ray spine Cobb angle was measured to evaluate the Keloid deformity correction, and the bone graft fusion was observed by CT examination. Results: All patients were followed up for 12 to 24 months. The total operation time of the traditional group was 273.3±21.1 min, and the total operation time of the modified group was 178.1±12.5 min, the difference between the two groups was statistically significant (t=8.981, P=0.0019). The differences between the two groups in steps 2 and 3 were statistically significant (t₂=4.614, P₂=0.036; t₃=9.089, P₃=0.020) . The difference in the total bleeding volume was statistically significant (t=8.529, P=0.011). The differences in the bleeding volume between the two groups in step 2 and step 3 were statistically significant (t₂=11.933, P₂=0.016; t₃=6.972, P₃=0.013). The Cobb angles of the traditional group before surgery, 1 week after surgery and half year after surgery were 40.2°±8.9°, 12.5°±6.8°, 10.4°±2.5°, respectively. The Cobb angles of the modified group before surgery, 1 week after operation and half year after surgery were 39.5°±6.3°, 10.4°±3.5°, 9.5°±1.9°, respectively. The differences in the Cobb angle between the preoperative, postoperative 1 week and postoperative half year were statistically significant(F_{modified group}=189.573, P_{modified group}=0.021; F_{traditional group}=194.699, P_{traditional group}=0.029). The bone fusion time in the osteotomy area was 3-6 months, with an average of 4.8 months. The VAC and ODI scores of half-year post operation of the traditional group were 2.1±0.3 and 34.1±4.3, and the improved group were 2.2±1.1 and 28.3±6.8, respectively, and the difference was not statistically significant. In the improved group, there were 1 case of over-excavation and 1 case of over-underexcavation (2/20), which were corrected in time during operation. In the traditional group, 4 cases (4/21) of dural tear occurred during the operation, and were repaired in time. Bone fusion was obtained half a year later. No clinical deaths, and no cases of surgical infection occured. Conclusion Tunnel forming technology is an alternative surgical procedure for treating old fractures of the thoracolumbar region with PSO, which can shorten the operation time, reducd intraoperative bleeding and reduce surgical complications.

Objective: To investigate the clinical efficacy of percutaneous fixation assisted by O-arm-based navigation for thoracolumbar fractures without neurologic deficits. Methods: A retrospective case control study was conducted to analyze the clinical data of 35 thoracolumbar fracture patients without neurologic deficits admitted to Henan Provincial People's Hospital from January 2018 to December 2018. There were 26 males and 9 females, aged 17-51 years, with an average age of 30.4 years. The injured segments were distributed at T₁₁ in 10 patients, T₁₂ in 15, L₁ in 11, and L₂ in 4 patients. A total of 19 patients (22 vertebrae, 98 pedicle screws) were treated with O-arm guided navigation assisted percutaneous internal fixation (Group A), and 16 patients (18 vertebrae, 82 pedicle screws) were treated with C-arm guided percutaneous internal fixation (Group B). The operation time, accuracy rate of nail placement, complications, Cobb angle of fracture vertebral body, visual analogue score (VAS) and Japanese Orthopaedic Association (JOA) score were recorded and compared before operation, 7 days after operation and at the last follow-up. Results: The patients were followed up for 2-12 months [(7.2±2.9)months] in Group A and 3-13 months [(7.1±3.3)months] in Group B. The operation time was (70.5±11.2)minutes in Group A and (81.3±10.9)minutes in Group B (P<0.01). A total of 93 screws were completely placed in the pedicle in Group A (accuracy rate of 95%), and 74 screws in Group B (accuracy rate of 90%) (P<0.01). There were no complications such as infection, pulmonary embolism, spinal cord, nerve injury or lower extremity deep vein thrombosis in either group. The Cobb angle of the fractured vertebral body at day 7 after operation in Group A and Group B was (9.4±2.1)° and (10.4±2.5)° respectively, while the Cobb angle of the fractured vertebral body at the final follow-up in Group A and Group B was (9.7±2.3)° and (11.4±2.9)° respectively. The postoperative Cobb angle was significantly increased compared with the preoperative Cobb angle (P<0.05), but there was no significant difference between the two groups (P>0.05). The VAS at day 7 after operation was (2.3±1.1)points and (2.8±1.0)points in Group A and Group B, respectively, while the VAS at the final follow-up was (0.7±0.7)points and (0.8±0.7)points in Group A and Group B respectively. The postoperative VAS was significantly decreased compared with the preoperative VAS (P<0.05), but there was no significant difference between the two groups (P>0.05). The JOA at day 7 after operation was (21.1±2.2)points and (21.8±2.5)points in Group A and Group B respectively, while the JOA at the final follow-up was (24.9±2.2)points and (23.8±1.9)points in Group A and Group B respectively. The postoperative JOA was significantly increased compared with the preoperative JOA (P<0.05), but there was no significant difference between the two groups (P>0.05). Conclusion For thoracolumbar fractures without neurologic deficits, percutaneous fixation assisted by O-arm-based navigation can shorten the operation time and deliver a higher accuracy rate in the placement of pedicle screws, in addition to the similar effects with percutaneous fixation assisted by C-arm in pain relief, function improvement and correction of fracture vertebral kyphosis.

Objective To investigate the clinical efficacy of unilateral approach painless vertebral augmentation in the treatment of severe osteoporotic vertebral compression fractures ( OVCFs) in the critically ill patients under lateral decubitus postition. Methods A retrospective case series study was conducted to analyze 97 patients with severe vertebral fractures admitted to the Henan Provincial People's Hospital from April 2004 to January 2017. There were 27 males and 70 females, aged 59-99 years [(78. 5 ± 13. 2) years]. There were 11 patients with three-segment fracture, nine patients with two-segment fracture and 77 patients with single fracture. All patients were treated with lateral decubitus unilateral approach for painless vertebral augmentation and received postoperative rehabilitation training guided by physicians. Preoperative and intraoperative blood loss were recorded. Preoperative and postoperative respiratory rate, heart rate, systolic pressure, oxygen saturation and acute physiology and chronic health evaluation score II ( APACHE II ) , height of vertebral compression site, and injured vertebrae Cobb angle were evaluated. The visual analogue scale ( VAS) and Oswestry dysfunction index ( ODI) were assessed to define function improvement. Meanwhile, the occurrence of re-fracture and complications were recorded. Results All patients were followed up for 3-8 months [(6.3 ±2.9)months]. The operation time was (69. 2 ± 25. 9) minutes, and the amount of intraoperative bleeding was (7. 5 ± 2. 6)ml. There were no significant differences in respiratory rate, heart rate, systolic blood pressure or oxygen saturation before operation and after operation ( P > 0. 05 ) . No surgical discontinuation or deterioration occurred. The APACHE II score was (15. 2 ± 3. 7) points before operation and (8. 4 ± 0.7)points at 24 hours after operation (P <0.05). The compression height parameter of the injured vertebraewas(17.2±3.6)mmbeforesurgery,(20.4±41.3)mmatoneweekaftersurgery,and(18.8± 1.3)mm at the last follow-up (P >0. 05). The Cobb angle was (25. 6 ± 9. 3)° before operation, (20.7±2.5)° at one week after operation and (18.5±3.1)° at the last follow-up (P>0.05). The VAS score was (8. 5 ± 1. 2)points before operation, (2. 1 ± 0. 3)points at one week after operation, and (3. 2 ± 1. 1)points at the last follow-up, respectively. The VAS scores at 1 week and the last follow-up were significantly improved compared with preoperative VAS ( P<0. 05 ) , but there was no significant difference between the former two (P>0. 05). The ODI value was 39. 9 ± 3. 4 before operation, 20. 2 ± 5. 2 at one week after operation, and 17. 2 ± 2. 0 at the last follow-up . The ODI values 1 week after operation and at the last follow-up were significantly improved compared with preoperative ODI ( P <0. 05),showing improvement trend during the follow-up (P<0. 05). No re-fracture occurred during the follow-up. No serious complications such as nerve injury, pulmonary embolism or death occurred during the operation and postoperative follow-up. Conclusions The unilateral approach painless vertebral augmentation for the treatment of severe OVCFs in critically ill patients under lateral decubitus position can improve the patient's operative tolerance and satisfaction, shorten the operation time, relieve postoperative pain and promote functional recovery. It is an alternative surgical procedure for the treatment of severe OVCFs in internal medicine.

Objective To evaluate the efficacy of modified posterior unilateral subtotal corpectomy osteotomy correction for old thoracolumbar vertebral fractures combined with kyphosis. Methods A retrospective case series study was conducted to analyze 18 patients with old thoracolumbar vertebral fractures combined with kyphosis admitted to the Henan Provincial People's Hospital from January 2012 to October 2016. There were 10 males and eight females, aged 25-70 years, with an average age of 38. 2 years. The injured segments and osteotomy segments included T11 in one patient, T12 in four, L1 in six, and L2 in seven. Five patients had neurological impairment symptoms classified as grade D according to Frankel's classification. All patients underwent the modified posterior unilateral subtotal corpectomy osteotomy correction. The operation time and intraoperative blood loss were recorded. The visual analogue score (VAS), Oswestry dysfunction index (ODI) and kyphosis Cobb angle were compared before operation, half a year after operation and at the last follow-up. The osteotomy fusion was evaluated by Suk criterion and Frankel grading was used to evaluate the recovery of nerve function. The complications were also recorded. Results All patients were followed up for 12-24 months, with an average of 17. 6 months. The operation time was 160-285 minutes [(190. 0 ± 42. 6) minutes, and the intraoperative blood loss was 500-800 ml [(610. 0 ± 134. 3) ml]. The difference of kyphosis Cobb angle between preoperative [(40.5±9.8)°] and [(5.5 ±1.6)°] at 6 months postoperatively had statistical significance (P <0. 05). Compared with the kyphosis Cobb angle of 6 months postoperatively [(5. 5 ± 1. 6)°], the Cobb angle at the final follow-up [(6. 2 ± 1. 5)°] did not change significantly (P>0. 05). The VAS score and ODI at 6 months after operation and at the final follow-up [(3. 1 ± 1. 3)points,(2. 7 ± 0. 7)points and 7. 5 ± 5. 1, 6. 4 ± 2. 5] were significantly different compared with those before operation [(7. 6 ± 2. 4)points, 68. 7 ± 10. 4] (P<0. 05). Bone cutting surface was healed osseously in all patients. The five patients with preoperative neurological impairment of grade D were assigned with grade E at the last follow up. There were two patients with dural rupture and one with pleural effusion during the operation. No complications such as nerve damage, infection or thrombosis occurred. No loosening, fracture or heterotopic ossification occurred during follow-up. Conclusion For old thoracolumbar vertebral fracture combined with kyphosis, the modified posterior unilateral vertebral column resection through unilateral approach can not only achieve the bone fusion between the injured vertebra and the adjacent vertebral body, but also avoid the shortening of the spine, correcting kyphosis and relieving pain, with low incidence of complications.

Objective To investigate the effect of LncRNA HULC on radiosensitivity of osteosarcoma cells. Methods Osteosarcoma cells OS732 was infected by shRNA HULC lentivirus, and the interference effect was determined by qRT-PCR. Osteosarcoma cells infected with shRNA HULC lentivirus were irradiated with 8 Gy X-rays. MTT, PI monochrome staining and Annexin V-FITC/PI double staining were used to detect cell proliferation, cell cycle and apoptosis, respectively. Western blot was used to detect the protein levels of p21, Cyclin D1, C-Caspase-3 and Cyt-C in cytoplasm and mitochondria. Plate cloning assay was used to evaluate cell radiosensitivity. Results The expression of HULC in osteosarcoma cells was significantly down-regulated by shRNA HULC lentivirus infection. Down-regulation of HULC or irradiation inhibited osteosarcoma cell proliferation [(100. 00±9. 65)％ vs. (71. 36±5. 27)％, (63. 48± 5. 93)％, t=4. 512, 5. 585, P<0. 05 ] , blocked cell cycle [ ( 50. 15 ± 5. 14 )％ vs. ( 62. 35 ± 4. 22 )％, (66. 05±5. 23)％,t=3. 177,3. 756,P<0. 05], induced cell apoptosis [(2. 98±0. 23)％ vs. (22. 61± 3. 26)％, (26. 14±2. 81)％,t=8. 898,10. 498,P<0. 05], promoted the expressions of p21 and Cyclin D1 in cells, down-regulated the level of C-Caspase-3 protein, increased the level of Cyt-C protein in cytoplasm, and down-regulated the level of Cyt-C protein in mitochondria. Downregulation of HULC combined with irradiation yield much more effects on cell proliferation inhibition [ ( 71. 36 ± 5. 27 )％, (63.48±5.93)％ vs. (49.32±5.76)％, t=4.890, 2.967, P<0.05], cell cycle arrest [(62.35± 4. 22)％, (66. 05±5. 23)％ vs. (77. 17±7. 54)％, t=2. 983, 2. 106, P<0. 05], apoptosis induction [(22. 61±3. 26)％, (26. 14±2. 81)％ vs. (36. 21±3. 26) ％,t=6. 164, 4. 564, P<0. 05] and the expressions of p21, Cyclin D1, C-Caspase-3 and Cyt-C in osteosarcoma cells. The radiosensitization ratio of down-regulation of HULC was 1. 432. Conclusions Down-regulation of HULC enhances radiosensitivity of osteosarcoma cells, which may be related to cell cycle arrest and apoptosis induction.

Objective To investigate the different operation methods for kyphosis deformity of ankylosing spondylitis(AS)complicated with cervical vertebral fracture and their effects.Methods A retrospective case series study was conducted to analyze the clinical data of 19 patients with AS kyphosis complicated with cervical vertebral fracture admitted to Henan People's Hospital from April 2007 lo October 2017.There were 18 males and one female,aged 28-73 years,with an average age of 38.6 years.Among the patients,17 were complicated with spinal cord dysfunction.According to the American spinal injury association(ASIA)classification,there were four patients with grade A,five with grade B,five with grade C and three with grade D.According to the degree of nerve injury and the displacement of fracture,reduction and fixation or orthopedic fixation were selected;14 patients with severe nerve injury(ASIA grades A-C)were treated with reduction and fixation,of which six were treated by simple anterior approach,two by simple posterior approach,five by combined anterior-posterior approach,and one by combined anterior-posterior approach 2 months after Halo fixation.Five patients with ASIA grade D or E were treated with orthopedic fixation.Firstly,kyphosis was corrected with manual technique and the Halo external fixator was installed,and then surgical fixation fusion was performed via simple posterior approach(one patient)or combined anterior-posterior approach(four patients).Visual analogue scale(VAS)was used to evaluate the relief of neck pain.The improvement of nerve function,the effect of orthopedic fixation,the fracture healing time and the postoperative complications were recorded.Results One patient died 11 days after operation due to pulmonary infection and respiratory failure.The remaining patients were followed up for 1-10 years,with an average of 27.3 months.The neck pain in all patients was relieved significantly,and the VAS score[(2.9±0.9)points]decreased significantly 3 days after operation compared with that before operation[(8.2±1.0)points](P＜ 0.05).The nerve function of 12 patients improved significantly(P＜ 0.05).The chin-brow vertical angle of the patients after orthopedic fixation was 60-180(mean,11.8°),suggesting that the level vision function was restored.Fracture healing time ranged from 3 to 8 months,with an average of 3.9 months.There were 4 patients with cerebrospinal fluid leakage and three patients with pulmonary infection.No complications such as wound infection and aggravation of nerve injury occurred.Conclusions For AS kyphosis combined with cervical spine fracture,if without severe nerve injury,manual correction of kyphosis and installation of Halo frame followed by fixation and fusion can effectively correct spinal deformity and improve the quality of life.Patients with severe spinal cord injury should avoid stage I correction and receive reduction of fracture and long segment fusion fixation as far as possible to facilitate the recovery of nerve function.
