Objective:To investigate the prognostic effect of femoral resection on patients with soft tissue sarcoma of the thigh with cortical bone involvement.Methods:This retrospective study included patients with soft tissue sarcoma of the thigh diagnosed and treated in the Second Affiliated Hospital of Zhejiang University School of Medicine from January 2014 to December 2021. Patients were divided into two groups based on whether femoral resection and reconstruction were performed with 20 in the resection group and 86 in the non-resection group. Propensity score matching (PSM) was used to control confounding variables. Overall Survival, recurrence free survival, metastasis free survival, and postoperative functional outcomes were compared between groups before and after PSM. Cox proportional hazards regression was used to identify risk factors for death, recurrence, and metastasis.Results:Before PSM, the 5-year overall survival (OS) and recurrence-free survival (RFS) rates were 46.7% and 36.7% in the resection group, compared to 69.7% and 60.3% in the non-resection group without significant differences ( P>0.05). However, the 5-year metastasis-free survival (MFS) rate was significantly lower in the resection group (40.0%) compared to the non-resection group (73.1%) ( P=0.021). After PSM, the 5-year OS, RFS, and MFS in the resection group were 46.7%, 36.7%, and 35.9%, respectively, compared to 45.0%, 39.4%, and 67.7% in the non-resection group, with no significant differences ( P>0.05). The median postoperative MSTS functional score after PSM was significantly lower in the resection group 23(18, 25) points than in the non-resection group 26.5(24.3, 27.8) points ( U=43.000, P=0.007). Multivariate Cox regression analysis identified grade III histology ( HR=3.794, P=0.002) and tumor involvement angle around the femur greater than 180° ( HR=2.729, P=0.030) as independent risk factors for death. Age over 55 years ( HR=4.185, P=0.015), tumor diameter greater than 8 cm ( HR=4.290, P=0.014), and involvement of the intermuscular compartment ( HR=3.794, P=0.017) were associated with increased risk of local recurrence. Grade III histology ( HR=3.848, P=0.006) and involvement of the intermuscular compartment ( HR=2.500, P=0.045) were associated with distant metastasis. Conclusion:For patients with thigh soft tissue sarcoma involving femoral cortex involvement but no medullary cavity invasion, bone resection did not improve survival, recurrence or metastasis compared with patients in non-resection group. A relatively more conservative surgical approach may be advisable to preserve limb function without compromising oncological prognosis.

Objective:To investigate the risk factors of pleural effusion after spinal separation surgery for patients with spinal metastatic tumors.Methods:A total of 427 patients with spinal metastatic tumors from January 2014 to January 2022 in the Second Affiliated Hospital of Zhejiang University School of Medicine were retrospectively analyzed. There were 252 males and 175 females, with an average age of 59±12 years (range, 15-87 years). All patients underwent separation surgery. Based on the chest CT within 1 month after surgery, the volume of pleural effusion was measured individually by reconstruction software. Pleural effusion was defined as small volume (0-500 ml), moderate volume (500-1 000 ml), and large volume (above 1 000 ml). Baseline data and perioperative clinical outcomes were compared between the groups, and indicators with statistically significant differences were included in a binary logistic regression analysis to determine the independent risk factors for the development of pleural effusion after isolation of spinal metastatic cancer. Receiver operating characteristic (ROC) curves were conducted to calculate the area under the curve (AUC) for each independent risk factor.Results:All patients successfully completed the operation. Among the 427 patients, there were 35 cases of large pleural effusion, 42 cases of moderate pleural effusion, and 350 cases of small pleural effusion. There were significant differences in tumor size (χ 2=9.485, P=0.013), intraoperative blood loss ( Z=-2.503, P=0.011), blood transfusion ( Z=-2.983, P=0.003), preoperative total protein ( Z=2.681, P=0.007), preoperative albumin ( Z=1.720, P= 0.085), postoperative hemoglobin ( t=2.950, P=0.008), postoperative total protein ( Z=4.192, P<0.001), and postoperative albumin ( t=2.268, P=0.032) in the large pleural effusion group versus the small and moderate pleural effusion group. Logistic regression analysis showed that decreased preoperative albumin ( OR=0.89, P=0.045) and metastases located in the thoracic spine ( OR=4.01, P=0.039) were independent risk factors for the occurrence of large pleural effusion after separation surgery. The ROC curve showed that the AUC and 95% CI for preoperative albumin, lesion location, and the combined model were 0.637 (0.54, 0.74), 0.421 (0.36, 0.48), and 0.883 (0.81, 0.92). The combined predictive model showed good predictive value. Conclusion:The volume of pleural effusion can be measured individually and quantitatively based on chest CT. Decreased preoperative albumin and metastases located in the thoracic spine are independent risk factors for the occurrence of large pleural effusion after separation surgery. The combined prediction of the two factors has better predictive efficacy.

Objective:To analyze the advantages and disadvantages of online and offline laboratory medicine continuing education and training, and to discuss the future continuing education and training mode under new technology development and new situation.Methods:A questionnaire was administered to the trainees who participated in the 2019 and/or 2020 national continuing medical education project—Clinical Application and Evaluation of New Technologies and Methods of Laboratory Medicine—sponsored by the Department of Laboratory Medicine, West China Hospital, Sichuan University. One hundred and twenty-four questionnaires were completed for the 2019 offline training, and 503 questionnaires were completed for the 2020 online training. The rank sum test, Fisher's exact test, and chi-square test were performed for statistical analysis with the use of SPSS 26.0.Results:The participants in 2020 were significantly younger and the proportion of female participants in 2020 was significantly higher compared with those in 2019. Intermediate titles or above accounted for 66.93% (83/124) in 2019, and intermediate titles or below accounted for 88.67% (446/503) in 2020. The proportion of people from Sichuan Province was significantly higher in 2019. The proportion of trainees from primary institutions was significantly lower in 2019. In 2019, public institutions were mainly tertiary hospitals (74.31%, 81/109), and the majority of participants from private institutions were from third party testing institutions (60.00%, 9/15). In 2020, the percentage of tertiary hospitals in public institutions decreased to 60.99% (258/423), while the percentage of community medical institutions increased to 10.64% (45/423), and 75.00% (60/80) of trainees from private institutions were from tertiary and secondary medical institutions. Trainees with lower educational levels were more likely to appreciate the value of the training course, especially with higher degrees of satisfaction with improvements in theoretical levels and practical skills, and participants from primary institutions believed that the training course could effectively improve their theoretical and practical levels. The number of participants who provided suggestions on laboratory medicine continuing education and training needs in 2019 (83.75%, 67/80) was higher than that in 2020 (48.51%, 244/503). The overall pass rate of post-training assessment in 2020 was 88.52% (424/479).Conclusions:Online and offline training modes have different audience groups and training effects. Online continuing education can provide training opportunities to more primary care personnel and junior and intermediate professionals, which is conducive to improving the basic professional literacy and testing skills of laboratory personnel on the whole. At the same time, the integration of online and offline modes will promote the development of laboratory medicine continuing education.

Objective: This meta-analysis aims to refine the understanding of the optimal choice between different cage shapes in transforaminal lumbar interbody fusion (TLIF) by systematically comparing perioperative data, radiological outcomes, clinical results, and complications associated with banana-shaped and straight bullet cages. Methods: A meticulous literature search encompassing PubMed, Embase, Scopus, Web of Science, China Knowledge Network, and Wanfang Data was executed up to October 5, 2023. Inclusion criteria focused on studies comparing banana-shaped and straight bullet cages in TLIF. The quality of included studies was assessed using appropriate tools such as the Newcastle-Ottawa Scale (NOS) for nonrandomized studies. Rigorous evaluations were performed for radiographic outcomes, including disc height (DH), segmental lordosis (SL), lumbar lordosis (LL), subsidence, and fusion rates. Clinical outcomes were meticulously evaluated using visual analogue scale (VAS), Oswestry Disability Index (ODI), and complications. Results: The analysis incorporated 7 studies, involving 573 patients (297 with banana-shaped cages, 276 with straight cages), all with NOS ratings exceeding 5 stars. No statistically significant differences were observed in operative time, blood loss, or hospitalization between the 2 cage shapes. Banana-shaped cages exhibited greater changes in DH (p = 0.001), SL (p = 0.02), and LL (p = 0.01). Despite statistically higher changes in ODI for straight cages (26.33, p < 0.0001), the actual value remained similar to banana-shaped cages (26.15). Both cage types demonstrated similar efficacy in VAS, complication rates, subsidence, and fusion rates. Conclusion Although banana-shaped cages can excel in restoring DH, SL, and LL, straight bullet cages can provide comparable functional improvements, pain relief, and complication rates.
