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 explore the application effect of preoperative autologous blood localization method in laparoscopic resection of gastric stromal tumors in unfavorable areas of the stomach.Methods:A retrospective analysis was conducted on the case data of 40 patients with gastric stromal tumors in unfavorable locations admitted to Jinjiang Hospital from January 2019 to December 2022. The patients were divided into a control group (intraoperative endoscopic localization method) and an autologous blood localization group according to different intraoperative lesion localization methods, with 20 cases in each group. The surgical time, intraoperative blood loss, hospitalization time, postoperative exhaust time, and adverse reactions were compared between the two groups.Results:The surgery time of the autologous blood localization group was shorter than that of the control group [(92.30±8.80)min vs (108.20±14.87)min, P<0.05]. There was no statistically significant difference in intraoperative bleeding, hospitalization time, and postoperative exhaust time between the two groups (all P>0.05). Two groups of patients did not show an increase in inflammatory indicators such as white blood cells and C-reactive protein on the day after surgery. Both groups of patients did not experience adverse reactions such as fever, abdominal pain, or postoperative complications. Conclusions:The autologous blood injection localization method provides a safe, simple, and effective method for preoperative localization of gastric stromal tumors in unfavorable areas of the stomach under laparoscopy, and is worthy of clinical promotion and use.

Objective:To compare the clinical efficacy and quality of life of patients between Billroth Ⅱ+ Braun anastomosis and simple Billroth Ⅱ anastomosis in digestive tract reconstruction after laparoscopic distal gastric cancer radical resection.Methods:A retrospective analysis was performed on clinical data of 68 patients who underwent laparoscopic distal gastric cancer radical resection in Jinjiang Municipal Hospital from January 2019 to January 2022. Forty patients who underwent Billroth Ⅱ+ Braun anastomosis were included in the observation group, and 28 patients who underwent simple Billroth Ⅱ anastomosis were included in the control group. Perioperative indicators and postoperative indicators one year after surgery were collected to observe the safety and efficacy of patients after surgery.Results:There were no significant differences in operation time, intraoperative bleeding volume, postoperative exhaust time, time to remove gastric tube and drainage tube, and postoperative hospital stay between the two groups (all P>0.05). There were also no significant differences in postoperative complications between the two groups ( P>0.05). One year after surgery, the incidence of food retention and residual gastritis in the observation group were lower than those in the control group (all P<0.05), while there were no significant differences in the incidence of bile reflux and reflux esophagitis between the two groups (all P>0.05). One year after surgery, nutritional evaluation showed that the total protein decline and prognostic nutritional index (PNI) in the observation group were lower than those in the control group, with significant differences (all P<0.05). The incidence of bloating and reflux symptoms in the observation group one year after surgery was lower than that in the control group, with significant differences (all P<0.05). Conclusions:Billroth Ⅱ+ Braun anastomosis is a safe method for digestive tract reconstruction after laparoscopic distal gastric cancer resection, which can improve patients′ quality of life after surgery.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Gastrointestinal neoplasms is the most common digestive tract neoplasms, and its incidence rate is increasing year by year. Compared with other solid tumors, the application of immune checkpoint inhibitors in gastrointestinal neoplasms is still in the stage of continuous exploration. This paper intends to review the relevant research and latest progress of immune checkpoint inhibitors in advanced gastric cancer, mismatch repair function defect/microsatellite high instability and mismatch repair function integrity/microsatellite stability or microsatellite low instability, and further evaluate the effectiveness and safety of immunotherapy combined with relevant studies.

Multiple myeloma (MM) is a common malignant hematological tumor in adults, which is characterized by clonal malignant proliferation of plasma cells in the bone marrow and secretion of a large number of abnormal monoclonal immunoglobulins (M protein), leading to bone destruction, hypercalcemia, anemia, and renal insufficiency (Alexandrakis et al., 2015; Yang et al., 2018). Since a large number of new drugs, represented by proteasome inhibitors and immunomodulators, have been successfully used to treat MM, treatment efficacy and survival of patients have been significantly improved. However, due to the high heterogeneity of this disease, patients have responded differently to treatments with these new drugs (Palumbo and Anderson, 2011; Wang et al., 2016; Huang et al., 2020). Growth and survival of MM cells depend on the bone marrow microenvironment, especially numerous inflammatory cytokines secreted by myeloma cells and bone marrow stromal cells, such as vascular endothelial growth factor (VEGF), interleukin (IL)‍-6, transforming growth factor-‍β (TGF‍‍-‍‍β), and IL-10. These cytokines can promote the growth of myeloma cells, induce angiogenesis, and inhibit antitumor immunity, and are often linked to patient prognosis (Kumar et al., 2017). In this era of new drugs, the prognostic values of the serum levels of these cytokines in MM need further evaluation.

Objective:To explore the value and advantages of perioperative nutritional support in enhanced recovery after surgery (ERAS).Methods:The clinical data of patients admitted to Jinjiang City Hospital for acute abdomen and undergoing surgery from April 2018 to January 2021 were collected. They were divided into two groups: the enhanced recovery after surgery group (ERAS group, 78 cases) and the traditional perioperative management group (CPM group, 75 cases). The nutritional risk assessment of NRS2002 was performed on admission to the two groups. The postoperative inflammatory indexes, nutrition and rehabilitation related indexes were compared between the two groups.Results:There was no significant difference in preoperative NRS 2002 score, operation method, operation time and blood loss between ERAS group and CPM group ( P>0.05). There was no significant difference in C-reactive protein (CRP), albumin (Alb) and prealbumin (PA) between ERAS group and CPM group before operation ( P>0.05). The ALb and PA of the two groups on the first day after operation were significantly lower than those before operation, and the CRP levels on the first, third, fifth and seventh day after operation were higher than those before operation( P<0.05), with significant difference. The CRP level of ERAS group was lower than that of CPM group on the third day after operation, with significant difference ( P<0.05). On the 7th day after operation, the levels of Alb and PA in ERAS group were higher than those in CPM group ( P<0.05). The recovery time of gastrointestinal function and hospitalization days in ERAS group were significantly reduced, and the total cost of hospitalization was significantly less than that in CPM group ( P<0.05). Conclusions:Perioperative effective nutritional support is helpful to accelerate the recovery of patients with acute abdomen. The application of enhanced recovery after surgery can effectively improve the nutritional status of patients with acute abdomen, reduce the incidence of complications and improve the clinical outcome of patients.
