Objective:To compare the clinical efficacy and adverse events of different postoperative radiotherapy strategies (adjuvant radiotherapy versus salvage radiotherapy) and different irradiation fields (prostate bed versus prostate bed + pelvic radiation) in patients after radical prostatectomy for prostate cancer.Methods:This retrospective analysis included clinical data from 115 patients with localized or locally advanced prostate cancer who received intensity-modulated radiotherapy (IMRT) after radical prostatectomy at Beijing Hospital between March 2014 and September 2023. Among them, 40 patients received adjuvant radiotherapy, and 75 received salvage radiotherapy. And 74 patients received irradiation to both the prostate bed and pelvic (prostate bed + pelvic radiation group), while 41 patients received irradiation to the prostate bed alone (prostate bed irradiation group). Comparison was made between the adjuvant radiotherapy group and salvage radiotherapy group, as well as between prostate bed + pelvic radiation group and prostate bed irradiation group, in terms of overall survival (OS), progression-free survival (PFS), locoregional recurrence-free survival (LRRFS), and the incidence of adverse events. Clinical characteristics were compared using the chi-square test. Survival rates were calculated using the Kaplan-Meier method and compared using the log-rank test. Prognostic factors affecting survival were analyzed using Cox multivariate regression.Results:The median follow-up duration was 73.1 months. The 5-year OS, PFS and LRRFS rates for the entire cohort were 96.4%, 86.4%, and 93.2%, respectively. A total of 59 patients (51.3%) experienced grade 1-2 acute radiotherapy-related adverse events, while 43 patients (37.4%) experienced grade 1-2 late radiotherapy-related adverse events. No grade ≥ 3 late adverse events were observed. There were no statistically significant differences in OS, PFS, or LRRFS between the adjuvant and salvage radiotherapy groups ( P = 0.807, 0.996, and 0.976, respectively), or in the incidence of grade 1-2 acute or late adverse events ( P > 0.05). The OS rate in the prostate bed + pelvic radiation group was significantly lower than that in the prostate bed irradiation group ( P = 0.036), while no significant differences were found in PFS or LRRFS ( P = 0.109 and 0.190, respectively), or in the incidence of grade 1-2 acute or late adverse events ( P > 0.05). Multivariable analysis showed no statistically significant differences in OS, PFS, or LRRFS between the adjuvant and salvage radiotherapy groups, or between the prostate bed and prostate bed + pelvic irradiation groups ( P = 0.756, 0.341, 0.605; 0.938, 0.987, 0.605, respectively). Conclusions:In the era of modern IMRT, both adjuvant and salvage radiotherapy, as well as prostate bed and prostate bed + pelvic irradiation, demonstrate similar efficacy and safety profiles after radical prostatectomy for prostate cancer. Treatment outcomes were favorable, and adverse events were minimal.

Objective:To investigate the clinical characteristics and prognosis of follicular lymphoma (FL) patients with different primary sites using the Surveillance, Epidemiology, and End Results (SEER) database.Methods:Clinical data of 7167 patients with early-stage FL (stage I-II) from the SEER database between 2000 and 2015 were respectively analyzed. Primary sites were divided into intranodal and extranodal types. Intranodal primary sites included supradiaphragmatic lymph nodes (LN), subphrenic lymph nodes and Waldeyer's ring. Extranodal primary sites consisted of skin, gastrointestinal tract, duodenum, head and neck, other sites. Prognostic factors and overall survival (OS) in patients with different primary sites were analyzed. OS rate was evaluated using Kaplan-Meier method and survival difference between primary sites was compared with log-rank test. Inverse probability treatment weighting (IPTW) and multi-variable analysis were applied to adjust for confounding factors. Multivariate Cox regression analysis of influencing factors of OS was performed.Results:The median age was 63 years old, with the median follow-up time of 63 months. There was no difference in prognosis among the intranodal groups or between the intranodal and extranodal groups. The 10-year OS rates of the supradiaphragmatic lymph LN ( n=2146), subdiaphragmatic LN ( n=2811), and the Waldeyer's ring ( n=151) groups were 70.7%, 69.9% and 73.4%, respectively ( P=0.422 for infradiaphragmatic LN vs. supradiaphragmatic LN, P=1.000 for Waldeyer's ring vs. supradiaphragmatic LN), and 70.3% and 68.9% for intranodal ( n=5108) and extranodal ( n=2059), respectively. There was no significant difference in OS between the groups ( P=0.581) after IPTW adjustment. The most common primary sites in extranodal disease were skin, gastrointestinal tract, head and neck, and duodenum. The 10-year OS for skin, gastrointestinal tract, and cutaneous was 74.2%, 74.7%, and 87.3%, respectively, significantly higher than 55.6% for other sites (duodenum vs. others sites, gastrointestinal vs. others sites, skin vs. others sites: all P<0.001). Multivariate Cox regression analysis revealed that difference in OS was not significant among the intranodal groups or between the intranodal and extranodal groups. However, different extranodal primary site was an independent prognostic factor for OS. Conclusions:Early FL patients with supradiaphragmatic LN, subdiaphragmatic LN and Waldeyer's ring, and between the intranodal and extranodal primary sites obtain similar prognosis. However, early-stage FL patients with different extranodal primary sites have prognostic differences. The prognosis of primary skin, gastrointestinal tract and duodenum is significantly better than that of other extranodal primary sites.

Objective:To establish reference ranges for left and right ventricular structure and function parameters using cardiovascular magnetic resonance (CMR) in healthy Tibetan natives residing at ultra-high altitudes, and analyze their influencing factors.Methods:This prospective study enrolled Tibetan healthy volunteers who underwent CMR examinations between September 2021 and August 2022. Participants were stratified into four age groups: 20-29, 30-39, 40-49, and 50-59 years. CMR-derived parameters included left ventricular ejection fraction (LVEF), right ventricular ejection fraction (RVEF), left/right ventricular end-diastolic volumes (LVEDV/RVEDV), left/right ventricular end-systolic volumes (LVESV/RVESV), and end-diastolic left ventricular mass (LVM at ED). Normally distributed data were compared between genders using independent samples t-test and among age groups using ANOVA. Non-normally distributed data were analyzed with Kruskal-Wallis test. Linear regression assessed relationships between parameters and gender, age, residential altitude, body surface area (BSA), and body mass index (BMI). Results:The study included 66 volunteers (27 males, 39 females), distributed as follows: 21 (20-29 years), 15 (30-39 years), 15 (40-49 years), and 15 (50-59 years). Reference values were: LVEF (62.6±5.7)%, RVEF (55.0±7.1)%, BSA-indexed LVEDV (60.6±12.1)ml/m2, RVEDV (65.5±14.8)ml/m2, LVESV (22.7±5.9)ml/m2, RVESV (29.6±8.1)ml/m2, and LVM at ED (39.1±8.0)g/m2. Gender and age significantly affected RVEF, RVESV, and LVM at ED ( P<0.05). Multivariate regression revealed:Gender independently predicted RVEF ( β=-5.556, P=0.003), RVESV ( β=5.421, P=0.007), and LVM at ED ( β=8.338, P<0.001). Age negatively influenced RVESV ( β=-0.202, P=0.019). BSA positively correlated with LVM at ED ( β=19.980, P=0.041). No significant associations were found with residential altitude or BMI ( P>0.05). Conclusion:This study establishes preliminary reference ranges for ventricular parameters in Tibetan ultra-high altitude natives, with gender, age, and BSA identified as key determinants of cardiac structural/functional indices.

Objective:To investigate the clinical efficacy of extracorporeal shock wave (ESWT) combined with stretching training in the treatment of chronic plantar fasciitis.Methods:A prospective case-control study was conducted to include the patients with chronic plantar fasciitis who had been admitted to Department of Orthopaedic Trauma, Nanfang Hospital, Southern Medical University from June 2021 to June 2022. A SPSS random number generator was used to randomize the patients into an experimental group (receiving treatment with ESWT combined with stretching training) and a control group (receiving stretching training only). Shear wave elastography (SWE) was used to quantitatively evaluate the elastic modulus of the plantar fascia. The 2 groups were compared in terms of visual analogue scale (VAS) pain score, plantar fascia thickness, and elastic modulus of the plantar fascia in the patients at 12 weeks after treatment; the correlation between VAS pain score and elastic modulus of the plantar fascia was examined using Spearman analysis in the patients at 12 weeks after treatment.Results:This study included a total of 41 patients (52 feet), 20 males and 21 females with an age of (49.9±8.2) years. There were 16 left sides, 14 right sides and 11 bilateral sides affected. The course of the disease was 7.0 (6.0, 12.0) months. The 2 groups were comparable because there were no significant differences in the general data before treatment between them ( P>0.05). The VAS pain score at 12 weeks after treatment for the experimental group was 1.0 (1.0, 2.0) points, significantly lower than that for the control group [3.0 (2.0, 3.0) points] ( P<0.05). The elastic modulus of the plantar fascia at 12 weeks after treatment for the experimental group was (79.48 ± 17.65) kPa, significantly higher than that for the control group [(57.08 ± 14.16) kPa] ( P<0.05). However, there was no statistically significant difference between the 2 groups in the thickness of the plantar fascia at 12 weeks after treatment ( P>0.05). There was a significant correlation between VAS pain score and elastic modulus of the plantar fascia after 12 weeks of treatment ( r = -0.708, P<0.001). Conclusion:In the treatment of chronic plantar fasciitis, combination of ESWT and stretching training is more effective than stretching training only.

Trauma center is an important link of trauma treatment, which is beneficial for professional integrated treatment of trauma patients and reduction of disability and death rate. The establishment of trauma rescue and treatment system is conducive to improving the regional trauma treatment capacity, rationalizing the layout of medical resources and standardizing the trauma treatment. Making full use of geographic information system (GIS) to analyze the big data such as the number of trauma patients, population, ground traffic situation and geographic information in the region and scientifically plan the number and location of trauma centers in the region is crucial to further optimize the geographic layout of trauma treatment centers, coordinate regional trauma treatment resources and improve the overall treatment capacity and is conducive to optimizing trauma treatment resources, improving regional trauma treatment capacity and reducing the disability and death rate of trauma patients. Based on domestic and foreign literature researches, the authors discuss how to use GIS to optimize the trauma rescue and treatment system in China in order to provide a useful reference for construction of regional trauma rescue and treatment system.

Objective: To investigate the clinical benefits of prophylactic supraclavicular irradiation (PSCI) in high-risk patients with limit-ed-stage small cell lung cancer (LS-SCLC). Methods: LS-SCLC patients without supraclavicular lymph node (SCLN) involvement and treat-ed with concurrent chemoradiation in the Department of Radiotherapy, Tianjin Medical University Cancer Institute and Hospital, be-tween July 2006 and July 2011, were retrospectively analyzed. According to our previous study, some were defined as SCLN recurrence high-risk patients. The recurrence rates of SCLN involvement and cancer-specific overall survival (CSS) in the different cohorts were ob-served. Univariate and multivariate analyses were performed both in the whole cohort and high-risk patients with recurrent SCLN in-volvement. Results: One-hundred and one patients with a median age of 57 years were included. As many as 50% of the high-risk pa-tients had recurrent SCLN involvement at the last follow-up as compared to 13.6% of the low-risk patients. The patients with recurrent SCLN involvement had a dramatically lower five-year CSS than those without recurrent SCLN involvement. The five-year CSS of high-risk patients with PSCI was similar to that of the low-risk patients; however, it was significantly higher than the five-year CSS of the high-risk patients without PSCI. The multivariate analysis revealed that advanced stage and recurrent SCLN involvement were signifi-cantly associated with poor CSS in the overall cohort. In the high-risk patients with recurrent SCLN involvement alone, only PSCI was as-sociated with improved CSS. Conclusions: PSCI not only reduced the recurrence of SCLN involvement significantly but also improved CSS in high-risk patients with LS-SCLC.

Objective To explore the value of 18F-FDG PET/CT in diagnosis of retroperitoneal fibrosis (RPF).Methods Totally 12 RPF patients underwent 18 F-FDG PET/CT scanning,and the characteristics of metabolic activity,distribution of retroperitoneal lesions and maximum standardized uptake value (SUVmax) were analyzed retrospectively.Results Among 12 patients,7 were initial evaluation patients,5 were post-treatment patients.Of 7 initial evaluation patients,there were 4 patients with secondary RPF,including prostate carcinoma,breast cancer and IgG4-related disease.Retroperitoneal mass isodense with muscle surrounding the abdominal aorta or the iliac arteries were found in 12 patients,and ureteral involvement were found in 11 paients (11/12,91.67％).SUVmax in initial evaluation patients (4.21±1.76) was higher than that in patients after treatment (1.46±0.25,P＜0.05).According to PET/CT,3 idiopathic RPF patients as initial evaluation with high metabolic activity lesions received immunosuppressive therapy including corticosteroids and tamoxifen,and 4 secondary RPF patients with high metabolic activity lesions received treatment based on causes.Among 5 post-treatment patients,3 continued to accept current corticosteroids maintenance dose,while 2 did not receive any other treatment.Conclusion PET/CT may be used to evaluate the activity and extension of lesions in patients with RPF.
