Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objectives:This study aims to explore the clinical significance of lateral pelvic sentinel lymph node biopsy (SLNB) using indocyanine green (ICG) fluorescence navigation in laparoscopic lateral pelvic lymph node dissection (LLND) and evaluate the accuracy and feasibility of this technique to predict the status of lateral pelvic lymph nodes (LPLNs).Methods:The clinical and pathological characteristics, surgical outcomes, lymph node findings and perioperative complications of 16 rectal cancer patients who underwent SLNB using ICG fluorescence navigation in laparoscopic LLND in the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College during April 2017 and October 2022 were retrospectively collected and analyzed. The patients did not receive preoperative neoadjuvant radiotherapy and presented with LPLNs but without LPLN enlargement (MRI showed the maximum short axes of the LPLNs were ≥5 mm and <10 mm at first visit).Results:All 16 patients were successfully performed SLNB using ICG fluorescence navigation in laparoscopic LLND. Three patients underwent bilateral LLND and 13 patients underwent unilateral LLND. The lateral pelvic sentinel lymph nodes (SLNs) were clearly fluorescent before dissection in 14 patients and the detection rate of SLNs for these patients was 87.5%. Lateral pelvic SLN metastasis was diagnosed in 2 patients and negative results were found in 12 patients by frozen pathological examinations. Among the 14 patients in whom lateral pelvic SLNs were detected, the dissected lateral pelvic non-SLNs were all negative. All dissected LPLNs were negative in two patients without fluorescent lateral pelvic SLNs. The specificity, sensitivity, negative predictive value, and accuracy was 85.7%, 100%, 100%, and 100%, respectively.Conclusions:This study indicates that lateral pelvic SLNB using ICG fluorescence navigation shows promise as a safe and feasible procedure with good accuracy. This technique may replace preventive LLND for locally advanced lower rectal cancer.

Objective:To compare the clinical efficacy of robot-assisted pedicle screw placement with visualization technology and conventional robot-assisted pedicle screw placement, and analyze the accuracy and safety of robot-assisted pedicle screw placement with visualization.Methods:This retrospective study analyzed data from 60 patients (39 males and 21 females) with an average age of 51.03±18.04 years (range 12-78 years) who underwent open spinal pedicle screw fixation surgery for thora columbar diseases at the Orthopedic Department of the First Affiliated Hospital of China Medical University between August 2020 and September 2022. The cases included 25 cases of spinal stenosis, 15 cases of lumbar fractures, 7 cases of thoracic fractures, 3 cases of lumbar spondylolisthesis, and 10 cases of spinal deformities. 30 patients underwent solid pedicle screw placement using robot-assisted visualization technology (visualization group), while the remaining 30 patients received hollow pedicle screw placement using conventional robot-assisted technology (conventional group). After screw placement, "O"-arm X-ray scans were performed for verification, and screw placement accuracy was evaluated based on the Gertzbein-Robbins standard. The study recorded and compared the time required for screw placement, number of fluoroscopy sessions, and perioperative complications between the two groups to provide a comprehensive assessment of surgical outcomes.Results:There were no significant differences in age and gender between the two groups ( P>0.05). In the visualization group, a total of 178 pedicle screws were placed, with 172 screws (96.6%) achieving satisfactory placement, while the conventional group placed 254 pedicle screws, with 240 screws (94.5%) achieving satisfactory placement. The difference in accuracy rates between the two groups was not statistically significant (χ 2=1.087, P=0.297). The visualization group required a mean of 2.60±1.03 fluoroscopy sessions during surgery, significantly less than the conventional group's mean of 5.57±2.12 sessions ( t=-6.860, P=0.001). Moreover, the visualization group had a shorter mean screw placement time of 13.23±3.68 minutes compared to the conventional group's mean of 24.68±15.75 minutes ( t=-3.870, P=0.040). All patients in both groups completed the surgery without postoperative complications such as infection, hematoma, or nerve root injury. Conclusion:The technique of robot-assisted pedicle screw placement with visualization effectively preserves the high precision achieved in conventional robotic surgery. With its advantage of real-time monitoring for screw position, it reduces the intraoperative fluoroscopy times and shortens the screw placement time, thereby further enhancing surgical efficiency.

Objective: To compare the clinical effects of endoscopic thyroidectomy using a modified gasless transsubclavian approach and the traditional neck approach for unilateral papillary thyroid carcinoma (cN0). Methods: The clinical data of 135 patients with cN0 papillary thyroid carcinoma who underwent unilateral thyroidectomy in the Department of Thyroid Surgery, the First Hospital of Jilin University from October 2020 to November 2022 were retrospectively analyzed. There were 37 males and 98 females, aging (43.2±8.8) years (range: 21 to 59 years). There were 51 cases using the modified gasless transsubclavian approach (TS group) and 84 cases using the traditional neck approach (TN group). Comparative analyses were performed between the operative results of the 2 groups by t-test, Wilcoxon rank sum test, and χ² test. Results: All endoscopic operations were successfully completed without conversion to the traditional neck approach. Compared to the TN group, the TS group had a longer operation time (M(IQR)) (73.5 (22.5) minutes vs. 90.0 (30.0) minutes, Z=-5.831, P<0.01), more postoperative drainage (60 (25) ml vs. 95 (45) ml, Z=-6.275, P<0.01), higher hospitalization costs (22 687 (3 488) yuan vs. 26 652 (2 431) yuan, Z=-6.944, P<0.01), and a higher rate of parathyroid autotransplantation (15.5% (13/84) vs. 60.8% (31/51), χ²=29.651, P<0.01). There was no significant difference in the total exposure rate of the central compartment, postoperative hospitalization time, the number of dissected lymph nodes, the number of metastatic lymph nodes, C-reactive protein ratio before and after operation, and preoperative and postoperative parathyroid hormone (all P>0.05). Conclusions: Endoscopic thyroidectomy using the modified gasless transsubclavian approach is safe for cN0 papillary thyroid carcinoma, with longer operating time, more postoperative drainage, higher hospitalization costs, and moredifficulty in preserving the inferior parathyroid gland in situ compared to traditional open surgery.

Objective:To investigate the curative effect of decompression with reserved superficial temporal artery for treatment of severe traumatic brain injury (sTBI).Methods:A retrospective case-control study was conducted to analyze the clinical data of 265 patients with sTBI who underwent decompressive craniectomy in Shaanxi Provincial People's Hospital from July 2016 to December 2019. Among them, 152 were males and 113 were females, with the age of 33-72 years [(50.1±12.8)years]. On admission, the Glasgow Coma Score (GCS) was 3-8 points [(5.7±1.4)points]. A total of 135 patients were treated with reserved superficial temporal artery decompression after admission (observation group) and 130 patients were treated with conventional decompression without deliberately preserving the superficial temporal artery (control group). The amount of intraoperative scalp bleeding, scalp healing time, cerebrospinal fluid incision leakage, healing degree and postoperative craniocerebral CT angiography (CTA) were compared between the two groups.Results:All patients were followed up for 7-15 days [(12.4±2.5)days]. The amount of intraoperative scalp bleeding was (15.4±4.5)ml in observation group and (65.2±4.7)ml in control group ( P<0.01). The healing time was (7.1±1.1)days in observation group and (9.5±2.3)days in control group ( P<0.01). There were 5 patients (3.7%) with cerebrospinal fluid incision leakage in observation group compared to 21 patients (16.2%) in control group ( P<0.01). There were 114 patients with Grade A healing in observation group compared to 91 patients in control group ( P<0.05). Based on the postoperative craniocerebral CTA, the superficial temporal artery was intact and the blood supply was normal in observation group, while the main trunk of the superficial temporal artery was disconnected from the zygomatic arch segment and the blood supply was incomplete in control group. Conclusions:For patients with sTBI, decompressive craniectomy with reserved superficial temporal artery can promote the healing of the scalp. Moreover, keeping the superficial temporal artery can significantly reduce the amount of bleeding during operation, reduce postoperative scalp healing time and incidence of cerebrospinal fluid incision leakage and assist cerebral blood perfusion.

Objective To prove the feasibility of a Fogging Process in fixing high-concentration radioactive aerosol ¹³¹I contamination. Methods High-concentration radioactive aerosol ¹³¹I contamination in an ¹³¹I-operating glovebox for radiopharmaceutical production was disposed by using fogging and fixing process. The aerosol ¹³¹I concentrations were detected and the results were analyzed. Results After a 120 minutes fixing, the ¹³¹I contamination in this glovebox reduced from(289 ± 9) DAC and (304 ± 6) DAC to (21.7 ± 2.0) DAC and (26.2 ± 1.8) DAC. After a 180 minutes fixing, the ¹³¹I contamination in this glovebox reduced from (259 ± 10) DAC to (1.80 ± 0.18) DAC. These results showed that no aerosol ¹³¹I contamination was raised again after 24-hours finishing this task. Conclusion Aerosol ¹³¹I concentration in a limited space could be controlled by using a fogging and fixing process, which could reduce the risk of internal exposure of staff. This process could be used by radiopharmaceutical production as an emergency management for dispose high-concentration radioactive aerosol ¹³¹I contamination.

Objective: To evaluate the value of different sequences magnetic resonance imaging (MRI) in rectal cancer re-staging after neoadjuvant chemoradiation therapy (NCRT). Methods: The clinical data of 117 patients with rectal cancer who underwent NCRT before surgery operation in Peking University cancer hospital from January 2016 to December 2018 were retrospectively analyzed. Among 117 patients, 101 patients underwent MRI scanning before and after NCRT, and 16 patient underwent MRI scanning after NCRT; T₂ weighted imaging (T₂WI) and diffusion weighted imaging (DWI) scanning were performed in all patients, and dynamic contrast enhancement (DCE) scanning was performed in 96 patients. T₂WI, T₂WI combined with DWI, T₂WI combined with DCE were used for T re-staging of rectal cancer after NCRT respectively, and the results of which were compared with those of pathology after operation. Results: The sensitivity of diagnosis of ypT_0-2 rectal cancer after NCRT using T₂WI combined with DWI, T₂WI combined with DCE respectively was significantly higher than that using T₂WI: 52.7% (29/55) and 30.4% (14/46) vs. 10.9% (6/55), and there was statistical difference (P<0.05). The accuracy rate and specificity of diagnosis of ypT₃ and ypT₄ rectal cancer after NCRT using T₂WI combined with DWI were significantly higher than that using T₂WI, with an accuracy rate of 60.7% (71/117) vs. 47.0%(55/117) and 92.3% (108/117) vs. 80.3% (94/117), and a specificity of 55.9% (33/59) vs. 23.7% (14/59) and 92.9% (105/113) vs. 80.5% (91/113), and there were statistical differences (P<0.05). The accuracy rate of down-staging after NCRT using T₂WI combined with DWI was significantly higher than that using T₂WI: 72.3% (73/101) vs. 58.4% (59/101), and there was statistical difference (P<0.05); there was no significant difference in accuracy rate between using T₂WI and using T₂WI combined with DWI and between using T₂WI combined with DWI and using T₂WI combined with DCE (P > 0.05). Conclusions T₂WI combined with DWI is superior to T₂WI in re-staging of rectal cancer after NCRT.

Objective To investigate the safety and efficacy of enhanced recovery after surgery (ERAS) used in laparoscopic colorectal cancer surgery.Methods We conducted a retrospective analysis of the medical records of 99 cases treated with ERAS programed laparoscopic colorectal cancer surgery (ERAS group) and 103 cases treated with traditional perioperative care and laparoscopic colorectal cancer surgery (controlled group) from Mar 2017 to Sep 2017 in our center.Results There was no significant difference in age,gender,BMI,ASA classification,tumor location,operation time,pathological stage and the incidence of postoperative complications between ERAS group and controlled group (all P ＞ 0.05).Compared to control group,ERAS had less blood loss,shorter time to pass first flatus,stool and start diet and shorter hospitalization day,with all the difference statistically significant [(60 ± 63)ml vs.(112 ± 245)ml,(3.0±0.8)dvs.(4.3 ±1.2)d,(3.5 ±1.0)dvs.(4.6±1.3)d,(4.1 ±1.2)dvs.(5.4± 2.0)d,(5.8±2.1)dvs.(7.8±2.5)d,t=-2.021、-9.216、-6.887、-5.252、-6.163,allP＜ 0.05].No patients in both groups suffered from readmission or death within 30 days after surgery.Conclusion Patients treated with ERAS programed laparoscopic colorectal cancer surgery is safe and effective,with rapid recovery and reduced hospital stay.

Objective To study the effect of early systemic rehabilitation therapy in elderly patients after hemiarthroplasty. Methods A total of 76 elderly patients (aged over 80 years old) with semi-hip replacement surgery in our hospital were randomly divided into experimental group (early postoperative systematic rehabilitation therapy after surgery) and control group (the conventional rehabilitation after surgery), with 38 patients in each group. visual analogue scale score (VAS score), hip functional assessment (Harris score), imaging evaluation, complication occurrence and quality of life score (SF-36 scale) at 1, 3, 6 months and 1 year of follow-up in the two groups were compared. Results No patients withdrew the follow-up. VAS scores in the experimental group at 1, 3, 6 months and 1 year of follow-up were lower than that in the control group, but no difference was observed (P＞ 0. 05). Significant differences in Harris scores between the two groups at 1 and 3 months after surgery were seen (P ＜ 0. 05). Harris scores at 6 months and 1 year after surgery in the experimental group were significantly higher than that in the control group, but there was no statistically significant difference between the two groups (P＞ 0. 05). The preoperative cortical index, filling rate of prosthesis pulp cavity and CC values of two groups showed no statistically significant differences (P＞ 0. 05). Filling of prosthesis pulp cavity after 3 to 5 days of the two groups had no obvious sink (＜ 2 mm) when compared with 1, 3, 6 months and 1 year after the replacement of X-ray plain film. The outreach angle of pulp angular position showed no change, white pulp and femoral components surrounding had no bright line, no prosthetic fractures, peripheral fractures and looseness were found. The incidence of complications in the experimental group was higher than that in the control group (34. 2％ vs. 13. 2％, P ＜ 0. 05). Preoperative total scores of SF-36 scale in the experimental group and control group were (407. 28 ± 25. 71), (412. 13 ± 19. 65), showing no differences (P＞0. 05), and postoperative total scores of SF-36 scale were (682. 46 ± 35. 21), (624. 59 ± 42. 76), respectively, at 3 month after operation, which were higher than preoperation (P ＜ 0. 01), and experimental group was higher than the control group (P ＜ 0. 01). Conclusion Early systemic rehabilitation can promote the recovery of hip function, improve the quality of life of elderly patients, reduce the incidence of postoperative complications, shorten the length of hospital stay, and reduce the economic burden.
