Apoptosis is an important means to regulate cell proliferation and maintain homeostasis. Recent researches have shown that the B-cell lymphoma-2 (BCL-2) family not only plays a dominant role in the regulation of normal cell apoptosis, but also plays a crucial role in the formation of tumor genesis, progression and subsequent drug resistance mediated by the escape mode of apoptosis. The phenomenon that BCL-2 family antagonized the apoptosis induced by antitumor drugs and then acquired drug resistance has been reported in the clinical treatment of hematologic lymphatic system tumors, breast cancer, lung cancer, gastric cancer and other diseases. Thus, specific inhibitors targeting anti-apoptotic members of the BCL-2 family have emerged with the development of research. In this paper, we systematically reviewed the regulation of apoptosis mediated by BCL-2 family and the drug resistance mediated by BCL-2 family. Meanwhile, we summarized the research advances of BCL-2 family specific inhibitors to provide new strategy for solving the problems on tumor therapeutic resistance and for finding new therapeutic targets in the future.
ObjectivesThe aim of this meta-analysis was to evaluate the adjuvant efficacy of dendritic cell (DC) vaccines against advanced colorectal cancer.MethodsCNKI, CBM, WanFang Data, VIP, PubMed, Web of Science, The Cochrane Library and EMbase were searched to identify studies on dendritic cell vaccine for CRC up to August 13rd, 2017. After independently screening the literature and extracting data, two researchers evaluated the risk of bias in the studies, and used RevMan 5.3.5 software for meta-analysis.ResultsA total of 10 studies involving 2 050 patients were included. Meta-analysis showed that cellular immunotherapy based on DC vaccine treatment can improve the 2-year and 3-year overall survival rate of patients with advanced colorectal cancer (HR=0.33, 95%CI 0.17 to 0.27; 0.26, 95%CI 0.12 to 0.56, P<0.05), while there was no statistically significant difference in 1-year overall survival rate (HR=0.48, 95%CI 0.19 to 1.20, P=0.12); DC-CIK-based cellular immunotherapy could improve 2-year and 3-year overall survival rates (HR=0.27, 95%CI 0.10 to 0.75; HR=0.15, 95%CI 0.04 to 0.54, P<0.05), the difference of 1-year overall survival rate was not statistically significant (HR=0.39, 95%CI 0.13 to 1.13, P=0.08); DC combined with chemotherapy could improve 2-year and 3-year overall survival (HR=0.24, 95%CI 0.10 to 0.56; HR=0.22, 95%CI 0.04 to 0.54, P<0.05); the difference of 1-year overall survival rate was not statistically significant (HR=0.34, 95%CI 0.06 to 2.03, P=0.24); median overall survival in the DC vaccine group (MSR=1.25, 95%CI 1.16 to 1.34, P<0.05) and median progression-free survival (MSR=1.39, 95%CI 1.25 to 1.53, P<0.05) were superior to the control group. Fever was the most common adverse reaction and most patients could be relieved after treatment.ConclusionsDendritic cells vaccines-based immunotherapy can effectively improve the later overall survival rate and prolong median OS of patients with advanced colorectal cancer with mild adverse reactions, however the improvement of short term survival rate is not obvious.
Objective To explore the feasibility of using high-definition thoracoscopy to identify sympathetic ganglia during endoscopic thoracic sympathicotomy for primary palmar hyperhidrosis. MethodsThe clinical data of patients with primary palmar hyperhidrosis who underwent thoracoscopic sympathectomy in Taikang Xianlin Drum Tower Hospital from June to July 2023 were retrospectively analyzed. At the same time, the operation video of patients with previous fluorescent thoracoscopic surgery was retrospectively analyzed.Results Finally 100 patients were collected, including 54 females and 46 males, with an average age of 21.92±6.56 years. Five patients were intravenously administered with indocyanine green before operation. During operation, the rate of ganglion display was 92.5% (740/800), the rate of ganglion variation was 32.0% (237/740), and the improvement rate of hand sweat was 100.0% (100/100). In 5 patients with near-infrared fluorescence imaging, the coincidence rate between the ganglion identified under white light and the ganglion displayed by fluorescence was 100.0% (38/38). The display rate of ganglion under white light was 95.5% (107/112), and the display rate under near infrared fluorescence imaging was 96.4% (108/112), and the coincidence rate was 99.1% (107/108). Conclusion With the wide clinical application of high-definition thoracoscopy, accurate thoracic sympathectomy has the feasibility of clinical application.

ObjectiveTo investigate the association between the stress-induced hyperglycemia ratio (SHR) and all-cause, cardiovascular, and diabetes-related mortality in patients with advanced cardiovascular-kidney-metabolic (CKM) syndrome, and to evaluate the value of SHR as an independent prognostic marker. MethodsThis retrospective cohort study used data from the 1999–2018 U.S. National Health and Nutrition Examination Survey (NHANES). A total of 2 135 patients with advanced CKM (stages 3 and 4) were included. Kaplan-Meier analysis and multivariable Cox regression models were applied to assess the relationship between SHR and mortality outcomes. Restricted cubic spline (RCS) analysis was employed to explore potential non-linear associations. Subgroup analyses were conducted to identify possible effect modifiers. ResultsOver a mean follow-up of 248 months, 674 all-cause, 198 cardiovascular, and 31 diabetes-related deaths occurred. Elevated SHR was significantly associated with diabetes-related mortality (HR=3.48, P<0.001) in a dose-response manner. SHR exhibited a U-shaped relationship with both all-cause and cardiovascular mortality (non-linearity P<0.001), indicating increased risk at both low and high SHR levels. Subgroup analyses revealed that sex, BMI, and hyperlipidemia significantly modified the association between SHR and diabetes-related death. ConclusionSHR is an independent predictor of mortality risk in patients with advanced CKM syndrome, particularly for diabetes-related death. These findings support the integration of SHR into risk stratification of high-risk CKM populations and provide a basis for metabolic stress-targeted interventions.
