Objective : To investigate the brain microvascular tissue block culture method for extracting primary rat brain microvascular endothelial cells and identify its effect. Methods : Brain tissue from 4-week-old Sprague Dawley rats was screened, pre-digested and solidified to obtain brain microvascular segments. These segments were subsequently placed in a CO2incubator for primary culture. The target cells were identified by cell morphology and immunocytochemical staining for factor Ⅷ-related antigen. Results : After a 48-hour culture periodin vitro, the short spindle cells crawled out from around the brain microvascular segments. After 72 hours, island-like cell culsters formed. After 96 hours the clusters fused and the cells formed a typical monolayer, cobble stone-like, and mosaic arrangement. Factor Ⅷ-related antigen immunocytochemical staining showed that the cytoplasm of the cells appeared brown-red, indicating positive expression; DAB stained the nucleus, showing blue-dark. Conclusion The brain microvascular tissue block culture method can isolate and culture primary rat brain microvascular endothelial cells.

Objective To use imaging features of pulmonary nodules to predict the risk of lymph node metastasis in patients with cT1-stage non-small cell lung cancer (NSCLC), providing a reference for clinical decision-making. Methods A retrospective analysis was conducted on the imaging features and postoperative pathological results of cT1 NSCLC patients who underwent surgical treatment at Linyi People’s Hospital from July 2019 to July 2022. Patients were grouped and analyzed according to lymph node metastasis status. Results A total of 1 123 patients were included, comprising 471 males and 652 females, with a median age of 59 (52, 66) years. Comparative analysis revealed that sex, age, nodule location, nodule size on imaging, solid component size, consolidation tumor ratio (CTR), average CT value, and tumor proximity to the pleura all influenced lymph node metastasis. A nomogram was constructed, indicating that the probability of lymph node metastasis in cT1 NSCLC was positively correlated with solid component size, CTR, and average CT value of the pulmonary nodule, and negatively correlated with patient age. The area under the receiver operating characteristic curve was 0.929. Conclusion For cT1 NSCLC patients, the probability of lymph node metastasis can be predicted by measuring the solid component size, CTR, and average CT value of the pulmonary nodule, in conjunction with patient age. However, relying solely on pulmonary nodule imaging characteristics is insufficient to determine a specific lymph node dissection strategy.

Objective To analyze ethnic differences in mutations of the PIK3CA and TP53 genes among breast cancer patients from the Han, Tibetan, and Hui ethnic groups in Qinghai, China, and their associations with clinicopathological characteristics. Methods A total of 382 breast cancer tissue samples were retrospectively collected from surgical patients (Jan 2020−Dec 2022), comprising 200 Han, 93 Tibetan, and 89 Hui ethnicity. Mutations in PIK3CA (E542K, H1047R, and E545K) and TP53 (R273H and R175H) were detected by using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Correlations between mutations and clinicopathological parameters were analyzed. Results Significant differences were observed in pTNM stage, lymph node metastasis, molecular subtypes, and PR status among the three ethnic groups. The overall mutation rate of PIK3CA and TP53 was 48.95%. The PIK3CA-p.E542K mutation rate in Tibetan cohort was significantly higher than those in Han and Hui cohort, whereas the detection rate of the PIK3CA-p.E545K mutation was lower in Tibetan cohort than that in Han cohort. The PIK3CA-p.E542K mutation was associated with an increased risk of lymph node metastasis. The TP53-p.R175H mutation was significantly correlated with advanced pTNM stage, vascular invasion, and triple-negative breast cancer. The PIK3CA-H1047R and E545K mutations were enriched in the luminal A subtype of breast cancer. Conclusion Considerable ethnic disparities exist in breast cancer mutation profiles in Qinghai, with the high-frequency PIK3CA-p.E542K mutation in Tibetan population potentially serving as a region-specific therapeutic target. Mutations are closely linked to tumor aggressiveness and molecular subtypes, highlighting the value of PIK3CA/TP53 mutation detection for early risk stratification and personalized treatment of breast cancer in high-altitude populations.

Objective To explore the effectiveness of an integrated laparoscopic simulation training course (best essential surgical technique training, BEST) in enhancing laparoscopic peritoneal suturing techniques in surgical residents.Methods As an integrated two-stage program, the BEST course applied basic laparoscopic training system with simple molds in phase Ⅰ training, and then adopted advanced laparoscopic training system, 3D Laparoscope and ex-vivo animal models in phase Ⅱ training. The laparoscopic suturing techniques were practiced in phase Ⅱ training. From August 2021 to July 2024, surgical residents in the second year of the national standardized training program were divided into pilot and control groups based on whether they had undergone the BEST course. Two cases of laparoscopic peritoneal suture were performed by the surgical residents under supervision in the department of gastrointestinal surgery. The operative time, quality of suture, and independent completion rate were compared between the two groups.Results A total of 33 surgical residents (19 in pilot group and 14 in control group) were included in this study, and a total of 66 cases of laparoscopic peritoneal suture were performed (38 in pilot group and 28 in control group). The operative time was significantly shorter in pilot group than that in control group (15.7 min vs. 17.5 min, P=0.025). The quality of suture was significantly better in pilot group compared to control group (P=0.023). In pilot group, all peritoneal sutures were performed by residents independently, whereas in control group, 3 cases (10.7%) were assisted by the supervisor, and the independent completion rate was different significantly (P=0.039).Conclusions The BEST course can help improve surgical residents′ laparoscopic peritoneal suturing techniques and could be promoted in the national standardized training program for surgical residents.
