Objective:To investigate the clinical efficacy of 3D laparoscopic radical gastrec-tomy of gastric cancer.Methods:The prospective randomized controlled study was conducted. The clinical data of 90 patients undergoing total laparoscopic radical gastrectomy of gastric cancer in Zhangzhou Affiliated Hospital of Fujian Medical University from January to December 2022 were selected. Patients were randomly divided into the 3D laparoscopic group and the 2D laparoscopic group by the method of random number table. Patients underwent 3D or 2D laparoscopic radical gastrectomy of gastric cancer. Observation indicators: (1) grouping of enrolled patients; (2) intra-operative and postoperative situations; (3) feelings of the major surgeon during the operation. Com-parison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of count data between groups wsa conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data between groups was conducted using the nonparametric test. Results:(1) Group of enrolled patients. A total of 90 patients eligible for total laparoscopic radical gastrectomy of gastric cancer were selected. There were 56 males and 34 females, aged (61±7)years. All 90 patients were randomly divided into the 3D laparoscopic group and the 2D laparoscopic group, with 45 cases in each group. There was no significant difference in gender, age, body mass index, hypertension, diabetes mellitus, history of abdominal surgery, surgical method, tumor site and TNM staging between the two groups ( P>0.05), indicating comparability. (2) Intraoperative and postoperative situations. The operation time of the 3D laparoscopic group and the 2D laparoscopic group were (196±12)minutes and (204±14)minutes, respectively. The digestive tract reconstruction time of the 3D laparoscopic group and the 2D laparoscopic group were (81±8)minutes and (87±12)minutes, respectively. There were significant differences in operation time and digestive tract reconstruction time between the two groups ( t=-2.85, -2.43, P<0.05). After surgery, 3 cases of the 3D laparoscopic group experienced complications (1 case of abdominal infection, 2 cases of intestinal obstruction), and 8 cases of the 2D laparoscopic group experienced complications (2 cases of anastomotic leakage, 2 cases of abdominal infection, 4 cases of intestinal obstruction). There was no significant difference in postoperative complications between the two groups ( χ2=2.59, P>0.05). (3) Feelings of the major surgeon during the operation. After surgery, the major surgeon completed a questionnaire survey. The score of image quality perception of the 3D laparoscopic group and the 2D laparoscopic group were 4.73±0.08 and 4.46±0.09, respectively. The score of hand-eye coordination experience of the 3D laparoscopic group and the 2D laparoscopic group were 4.60±0.09 and 4.55±0.08, respectively. The score of operation comfort of the 3D laparoscopic group and the 2D laparoscopic group were 4.81±0.05 and 4.62±0.08, respectively. The score of eye comfort of the 3D laparoscopic group and the 2D laparoscopic group 4.49±0.07 and 4.68±0.07, respectively. There were significant differences in the above indicators between the two groups ( t=15.04, 2.57, 13.51, -12.88, P<0.05). Conclusions:Compared with 2D laparoscopy, 3D laparoscopic radical gastrec-tomy of gastric cancer has shorter operation time and digestive tract reconstruction time, does not increase postoperative complications, and has better feelings of the major surgeon in image quality perception, hand-eye coordination experience and operation comfort.

Background and Aims:The completeness of lymph node dissection in laparoscopic radical gastrectomy for gastric cancer directly affects postoperative patient prognosis.Indocyanine green(ICG)fluorescence-guided navigation,as an emerging auxiliary technique,enables real-time visualization of lymphatic drainage pathways and enhances surgical precision.This study was performed to evaluate the impact of ICG fluorescence navigation on lymph node dissection,positive lymph node detection,and patient prognosis during laparoscopic D2 radical gastrectomy for gastric cancer.Methods:The clinical data of 168 patients who underwent laparoscopic radical gastrectomy at Zhangzhou Affiliated Hospital of Fujian Medical University from January 2021 to December 2022 were retrospectively analyzed.Among them,51 patients received ICG-guided surgery(ICG group),and 117 underwent conventional surgery(non-ICG group).Perioperative variables,extent of lymph node dissection,positive lymph node detection efficiency,and postoperative survival outcomes were compared between the two groups.Results:There were no statistically significant differences between the two groups in baseline clinicopathologic characteristics,as well as operative time,intraoperative blood loss,postoperative recovery,and incidence of surgical complications(all P>0.05).The ICG group had a significantly higher mean number of lymph nodes dissected than the non-ICG group(48.62 vs.37.20,P<0.001),with a greater proportion of patients achieving≥30 nodes dissected(92.16％vs.69.23％,P=0.001).Stratified analysis showed a significantly higher number of dissected lymph nodes in the ICG group at D2 stations,the supra-pancreatic region(stations 7,8,9,11),in total gastrectomy,T3-4 stage,and stage Ⅲ patients(all P<0.01).In the ICG group,the number and positivity rate of fluorescent lymph nodes were significantly higher than those of non-fluorescent nodes(30.31 vs.17.36;2.03 vs.0.94,both P<0.05).The diagnostic sensitivity of ICG fluorescence imaging for positive lymph nodes was 68.4％,with a negative predictive value of 94.6％for non-fluorescent nodes.No significant differences were observed between the two groups in terms of adjuvant therapy,overall survival(HR=0.737,P=0.471),or disease-free survival(HR=0.502,P=0.089).Conclusion:ICG-guided navigation in laparoscopic radical gastrectomy for gastric cancer is safe and significantly improves lymph node yield,particularly in the supra-pancreatic region,total gastrectomy,and advanced-stage patients.It also enhances positive node detection.However,no survival benefit has been observed in the short term.Further multicenter studies with long-term follow-up are warranted to confirm its clinical value and optimize intraoperative navigation strategies.

Objective:To investigate the impact of neoadjuvant immunotherapy combined with chemotherapy on the safety and efficacy of radical resection in patients with cT3-4NxM0 gastric cancer.Methods:A retrospective cohort study method was used. The clinicopathological data of 515 patients who underwent radical gastrectomy after neoadjuvant treatment at Second Department of Gastric Surgery,Fudan University Shanghai Cancer Center and Department of Gastric Surgery,Zhangzhou Hospital Affiliated to Fujian Medical University from January 2020 to June 2023 were collected. Among them,379 patients received neoadjuvant chemotherapy alone(chemotherapy group),and 136 patients received neoadjuvant immunotherapy combined with chemotherapy(immunotherapy group). There were 382 males and 133 females,with an age of (58.4±10.9)years(range:26 to 85 years). To reduce the influence of potential confounding factors,a 1∶1 propensity score matching method was adopted,and the clamp value was 0.02. The peri-operative safety,imaging and postoperative pathological tumor regression,and prognosis were compared by independent sample t-test, Mann-Whitney U test, χ 2 test or Fisher exact probability method between the two groups. The Kaplan-Meier method was used to draw survival curves, and the differences between groups were compared by Log-rank test. Results:After matching, there were 101 patients in each of the chemotherapy group and the immunotherapy group. The baseline data of the patients in the two groups were evenly distributed (all P>0.05). According to the RECIST 1.1 criteria, the complete response rate (11.9% (12/101) vs. 4.0% (4/101)), partial response rate(68.3%(69/101) vs. 53.4%(54/101)), stable disease rate (17.8%(18/101) vs. 39.6%(40/101)) and disease progression rate (2.0%(2/101) vs. 3.0%(3/101)) between the immunotherapy group and the chemotherapy group were no statistical defferences ( χ2=14.374, P=0.002), and objective response rate (80.2%(81/101) vs. 57.4%(58/101), χ2=12.203, P<0.01) in the immunotherapy group was higher than that in the chemotherapy group. The results of postoperative pathological examination showed that the immunotherapy group had a higher complete response rate (16.8%(17/101) vs. 6.9% (7/101), χ2=4.728, P=0.030) and major pathological response rate (42.6%(43/101) vs. 23.8% (24/101), χ2=8.062, P=0.005). For the two groups, the operation time (175.0(76.0)minutes vs. 160.0 (30.0)minutes, Z=-0.059, P=0.953), intraoperative blood loss (110.0 (150.0)ml vs. 100.0 (120.0)ml, Z=-0.370, P=0.712), overall incidence of postoperative complications (20.8%(21/101) vs. 18.8%(19/101), χ2=0.125, P=0.724) and incidence of severe complications (5.0%(5/101) vs. 3.0%(3/101), χ2=0.130, P=0.718) were comparable. The median follow-up time of all patients was 46 months(range: 19 to 61 months). The 3-year overall survival rate (63.2% vs. 54.4%, P=0.035) and progression-free survival rate (59.1% vs. 45.6%, P=0.022) of the immunotherapy group were higher than those of the chemotherapy group. Meanwhile, there were no statistically significant differences in the incidence of neoadjuvant-treatment-related adverse events (48.5%(49/101) vs. 40.6% (41/101), χ2=1.283, P=0.411) and the incidence of severe adverse reactions of grade 3 or above (13.9% (14/101) vs. 10.9% (11/101), χ2=0.257, P=0.522) between the two groups. Conclusion:Neoadjuvant immunotherapy combined with chemotherapy can significantly improve the imaging and postoperative pathological tumor response rates and 3-year survival rate of patients with locally advanced gastric cancer,without increasing the incidence of postoperative complications and neoadjuvant treatment-related adverse event.

The management of antibiotic-resistant, bacterial biofilm infections in skin wounds poses an increasingly challenging clinical scenario. Pseudomonas aeruginosa infection is difficult to eradicate because of biofilm formation and antibiotic resistance. In this study, we identified a new benzothiazole derivative compound, SN12 (IC₅₀ = 43.3 nmol/L), demonstrating remarkable biofilm inhibition at nanomolar concentrations in vitro. In further activity assays and mechanistic studies, we formulated an unconventional strategy for combating P. aeruginosa-derived infections by targeting the two-component (Gac/Rsm) system. Furthermore, SN12 slowed the development of ciprofloxacin and tobramycin resistance. By using murine skin wound infection models, we observed that SN12 significantly augmented the antibacterial effects of three widely used antibiotics-tobramycin (100-fold), vancomycin (200-fold), and ciprofloxacin (1000-fold)-compared with single-dose antibiotic treatments for P. aeruginosa infection in vivo. The findings of this study suggest the potential of SN12 as a promising antibacterial synergist, highlighting the effectiveness of targeting the two-component system in treating challenging bacterial biofilm infections in humans.
