Background/Aims: Biliary tract cancer (BTC) frequently harbors KRAS mutations, which are associated with resistance to traditional treatment and a poor prognosis. Synthetic lethality (SL) strategy may provide other targets of KRAS. Therefore, we aim to identify and validate potential therapeutic targets of KRAS for the treatment of BTC via SL. Methods: The dependency (DepMap) projects were used to predict the synthetic lethal gene of KRAS. FDA-approved anticancer drug library was applied to screen potential drugs effective against KRAS-mutant BTC. Furthermore, the synthetic lethal effects or corresponding mechanisms of potential genes and drugs on BTC were investigated using KRAS-mutant and KRAS-wild type BTC cell lines, patient-derived xenografts (PDX), and KRAS oncogene-driven tumor models, as well as other KRAS-mutant cancer cell lines. Results: Initially, we discovered that the loss of GATA2 reduced the viability of KRAS-mutant but not KRAS-wild-type BTC. Subsequently, the drug library screened out disulfiram, which primarily exerts a synthetic lethal effect by inhibiting interleukin-1β (IL-1β) in KRAS-mutant BTC. Mechanistically, GATA2 specifically enhanced the transcription of IL-1β to promote NF-κB signaling in KRAS-mutant BTC. IL-1β inhibition phenocopied GATA2 deficiency, leading to reduced KRAS-mutant BTC viability. These synthetically lethal effects were confirmed using PDX, a KRAS oncogene-driven tumor model, as well as in other KRAS-mutant cancer cell lines. Conclusions In summary, these results indicate that inhibiting GATA2/IL1β could be a therapeutic strategy in KRAS-mutant BTC and potentially other cancers.

Objective:To investigate the impact of virtual navigation bronchoscopy on perioperative information in patients undergoing thoracoscopic pulmonary resection.Methods:Employed three distinct propensity score matching models to effectively address the baseline data disparities among patients undergoing thoracoscopic pulmonary resection. Categorized the patients into two groups: pulmonary wedge resection and pulmonary segmentectomy. Compared the disparities in clinical characteristics, intraoperative lesion resection, and postoperative recovery between patients who underwent virtual navigation bronchoscopy assisted localization prior to surgery and those who did not employ any specific localization methods.Results:This reserch included a total of 127 patients who underwent localization assisted by virtual navigation bronchoscopy, and 122 patients who did not undergo specialized localization. After propensity score matching, the navigation group demonstrated a statistically significant reduction in intraoperative blood loss[model 3, 40(20, 50) ml vs. 50(20, 100) ml, P=0.027], drainage volume on the first day post-surgery[model 3, 100(50, 175) ml vs. 150(100, 220) ml, P=0.023], and incidence of residual pleural effusion(model 3, 31 cases vs. 38 cases, P=0.046) compared to the non-positioning group among patients undergoing pulmonary wedge resection. In the pulmonary segmentectomy group, we observed a reduction in intraoperative blood loss[model 3, 50(30, 100) ml vs. 100(50, 100) ml, P=0.003] and incidence of residual pneumothorax(model 3, 18 cases vs. 28 cases, P=0.012) in patients who underwent navigation-assisted procedures compared to those without specialized positioning. Conclusion:The utilization of virtual navigation bronchoscopy for preoperative localization assistance in thoracoscopic sublobectomy(including wedge resection and segmental resection) may represent a viable approach to mitigate intraoperative injury and facilitate postoperative recovery.

Objective:To explore the effects of internet-based group cognitive-behavioral therapy(IGCBT)on the depressive and anxiety symptoms in patients with major depressive disorder(MDD).Methods:Eighty pa-tients with MDD were recruited and randomly divided into IGCBT combined drug therapy group and control group with drug therapy.Blind assessments were performed using the Hamilton Depression Scale(HAMD)and Hamilton Anxiety Scale(HAMA)three times at baseline,4 weeks after treatment and 8 weeks after treatment,respectively.Results:The effective rates of HAMD and HAMA at the end of the 4th and 8th week,and the effective rates of HAMA at the end of the 8th week were higher in the combined treatment group than those in the control group(Ps＜0.05).The total scores of HAMD and HAMA in the combined treatment group and the control group were lower at the end of the 4th and 8th week than those at baseline(Ps＜0.001).The total scores of HAMD and HAMA were lower in the combined treatment group than those in the control group at the baseline,4 weeks and 8 weeks after treatment(Ps＜0.01).Conclusion:It suggests that intemet-based group cognitive-behavioral therapy combined with antidepressant medication has a better effect on relieving depressive and anxiety symptoms in patients with ma-jor depressive disorder than drug therapy alone,and especially has a better effect on improving anxiety symptom.

Glioblastoma (GBM) is an exceptionally aggressive tumor that originates in the brain,characterized by a notably high mortality rate and a limited responsiveness to pharmacological interven-tions.In recent years,antibody-drug conjugates (ADCs) have emerged as a focal point in the advance-ment of anti-cancer therapeutic research,merging the precise targeting capabilities of antibodies with the powerful killing power of cytotoxins.In recent years,the outcomes of numerous clinical trials investi-gating ADCs targeted against GBM have been notably encouraging.This article endeavors to provide a comprehensive overview of the prevalent ADCs targets for GBM therapy,which include the epidermal growth factor receptor,the cluster of differentiation,the mannose receptor family,the integrin family,and the galectin family.Furthermore,it will delve into the contemporary landscape of ADCs drug research and the significant challenges encountered in the application of ADCs for GBM treatment.

Objective:To evaluate the safety and efficiency of a modified double-tract reconstruction procedure─proximal gastrectomy with piggyback interposed jejunal single-channel reconstruction (PJIR-STR) for early SiewertⅡ adenocarcinoma of esophagogastric junction (AEG).Method:Data of 8 SiewertⅡ AEG patients at Shanxi Tumor Hospital and undergoing PJIR-STR from May 2018 to Oct 2019 were retrospectively analyzed. The gastroesophageal reflux disease questionnaire (GerdQ) was used to score the patients at 3, 6, 12, and 18 months after surgery. The severity of postoperative reflux esophagitis was assessed by gastroscopy at 3, 6 months after surgery, using the Los Angeles Classification criteria.Result:All patients recovered well after surgery without serious complications. No obvious gastroesophageal reflux was observed in all patients at different periods (All of the GerdQ scores were <8 points.) The results of gastroscopy showed that 1 patient was diagnosed as grade B reflux esophagitis at 3, 6 months after surgery, which was responsive to conservative treatment, and the other 7 patients had no grade B or above reflux esophagitis.Conclusion:PJIR-STR is a feasible, safe reconstruction with excellent efficiency of dual anti-reflux for the SiewertⅡ AEG.
