Objective:To explore the long-term survival outcomes of patients with anaplastic thyroid cancer (ATC) and analyze key factors influencing the prognosis.Methods:A retrospective analysis was conducted on the clinical and follow-up data of 77 ATC patients treated at the Sun Yat-sen University Cancer Center from March 2000 to July 2022, with tumor-specific survival as the primary endpoint. The Kaplan-Meier method was used to plot the survival curves, and univariate and multivariate Cox regression analyses were performed to identify the prognostic factors.Results:Among the 77 patients, 64 underwent surgical treatment, with 33 receiving surgery alone, 8 undergoing surgery combined with chemotherapy, 13 undergoing surgery with radiotherapy, 1 undergoing surgery with chemotherapy and radiotherapy, 2 receiving surgery combined with chemotherapy and targeted therapy, 3 receiving surgery with targeted therapy, and 4 receiving surgery with immunotherapy and targeted therapy. Among the 13 patients who did not undergo surgery, 2 received chemotherapy alone, 3 received targeted therapy alone, 1 received immunotherapy alone, 1 received chemoradiotherapy, 5 received chemotherapy combined with immunotherapy, and 1 received immunotherapy combined with targeted therapy. The median follow-up time was 8.4 months, with 58 patients (75.3%) died, and the median survival time was 6.63 months. Univariate Cox regression analysis showed that C-reactive protein, monocyte count, lymphocyte count, abnormal albumin levels, the maximum diameter of the primary tumor, BMI, and whether immunotherapy was administered were significantly associated with survival in ATC patients (all P＜0.05). Multivariate Cox regression analysis indicated that immunotherapy was an independent factor for survival in ATC patients ( HR=0.18, 95% CI: 0.05-0.62, P=0.007). Among the 40 patients admitted after 2015, the 11 patients who received immunotherapy had a median survival time of 17.2 months, which was superior to the 29 patients who did not receive this treatment (median survival time 6.2 months, P=0.03). Conclusions:ATC patients receiving immunotherapy had a better prognosis and longer survival. Additionally, elevated C-reactive protein, abnormal albumin, monocyte count, lymphocyte count, and BMI might be associated with poorer prognosis in ATC. Tailoring treatment based on the individual characteristics of ATC patients may be beneficial for their long-term survival.

Objective To investigate the relationship between polymorphisms at the rs3093030 and rs5498 loci of the intercellular adhesion molecule-1(ICAM-1)gene in combination with high sensitive C-reactive protein(hs-CRP)and susceptibility to type 2 diabetes mellitus complicated with HTN(T2MH)susceptibility.Methods 200 newly diagnosed T2DM patients,175 T2MH patients and 200 healthy controls from Affiliated Hospital of Guilin Medical University between September 2021 and January 2022.Single nucleotide polymorphisms(SNP)-scan high-throughput technology was used to detect the genotyping of serum rs3093030 and rs5498 polymorphisms in the study subjects and to detect hs-CRP levels in peripheral plasma to analysed and explore the correlation between them and the development of T2MH.Results The peripheral blood hs-CRP expression level of patients in the T2MH group[2.65(1.18,6.50)mg/L]was significantly higher than that in the T2DM group[1.82(0.80,4.48)mg/L]and healthy controls[1.02(0.54,2.29)mg/L],and the differences were statistically significant(Z=-2.729,-7.132,all P<0.001).After population classification by genotype,it was found that compared with healthy controls,rs3093030 CC(Z=-3.912,-5.800),rs5498 AA(Z=-3.293,-4.944)and AG(Z=-3.275,-4.872)genotypes had significantly higher hs-CRP levels.The peripheral blood hs-CRP levels of patients with rs3093030 CT genotype in the T2MH group were significantly higher than that of healthy controls(Z=-3.987),and the differences was statistically significant(all P<0.001),respectively.Meanwhile,regression analysis showed that HS-CRP was a risk factor for both T2MH group and healthy control group(OR=1.181,95%CI=1.095～1.274,P<0.001).Conclusion There is a correlation between ICAM-1 gene rs3093030 and rs5498 polymorphisms combined with hs-CRP levels in peripheral blood and the pathogenesis of T2MH patients.

Objective To investigate the impact of anti-reflux modified duodenal exclusion surgery on glucose metabolism in rats with type 2 diabetes mellitus (T2DM), and to elucidate the role of the duodenum in maintaining glucose homeostasis. MethodsForty male Sprague-Dawley rats aged 5 weeks were fed a high-fat diet and induced with T2DM using low-dose streptozotocin. Thirty-six rats that met the T2DM model criteria were randomly divided into three groups: the simple duodenal exclusion surgery group (DE group), the anti-reflux modified duodenal exclusion group (MDE group), and the sham operation group (SO group), with 12 rats in each group. Gastroenterography was performed 4 weeks after surgery, and the body weight, fasting blood glucose levels, and serum glucagon-like peptide-1 (GLP-1) concentrations were measured before surgery and at 1, 2, 4, and 8 weeks post-surgery. Eight weeks post-surgery, the rats were euthanized, and a 1 cm segment of the biliopancreatic loop was collected from each group for pathological sectioning and HE staining to observe the intestinal mucosal villus length under an optical microscope. Results Gastroenterography showed that there was significant reflux of the contrast agent into the duodenal lumen in the DE group, while no reflux was observed in the MDE group. At one week post-surgery, the body weights of rats in all three groups significantly decreased compared to before surgery (P<0.05), and then the body weights of all groups increased over time, with no significant differences between the groups (P>0.05). Compared with the SO group, the fasting blood glucose levels in the MDE and DE groups significantly decreased at all time points post-surgery (P<0.05), while GLP-1 concentrations significantly increased (P<0.05). The fasting blood glucose levels in the MDE group were lower than those in the DE group at all time points post-surgery (P<0.05), but there were no significant differences in serum GLP-1 concentrations between the MDE and DE groups (P>0.05). Regarding intestinal mucosal morphology, the villus lengths of the biliopancreatic loops in the MDE group were significantly shorter than those in the DE and SO groups (P<0.05). Conclusion Anti-reflux modified duodenal exclusion surgery effectively improves glucose metabolism in T2DM rats by preventing the reflux of chyme into the diverted duodenum, thereby enhancing its hypoglycemic effect.

Objective:To explore the influence of central obesity on the risk of breast cancer and the possible role of dietary factors in its prevention.Methods:This study is a case-control study including a total of 212 participants, of whom 63 were with breast cancer, 71 were with breast nodules, and 80 were healthy controls. We used bioelectrical impedance analysis to measure body composition,and adopted the food frequency questionnaire to investigate dietary intake of participants.Results:The visceral adipose tissue ( OR=1.03, 95% CI: 1.003 to 1.077) and trunk fat mass ( OR=1.470, 95% CI: 1.104 to 2.184) were independently associated with the increased risk of breast cancer. Dietary patterns characterized by low dietary intake of beans and dairy products ( OR=1.300, 95% CI: 1.044 to 1.619) and high intake of cereals and red meat ( OR=2.254, 95% CI: 1.705 to 2.982) will increase the risk of breast cancer. Moreover, high meat intake ( β=0.268, 95% CI: 0.034 to 0.503) would advance the accumulation of visceral fat, while high bean intake ( β=-0.485, 95% CI: -0.865 to -0.104) would inhibit. Conclusions:Central obesity is an independent risk factor for breast cancer. Insufficient intake of beans and excessive intake of red meat are identified as factors that can exacerbate central obesity in breast cancer patients.

The estimated new cases of breast cancer (BC) patients were 2.26 million in 2020, which accounted for 11.7% of all cancer patients, making it the most prevalent cancer worldwide. Early detection, diagnosis and treatment are crucial to reduce the mortality, and improve the prognosis of BC patients. Despite the widespread use of mammography screening as a tool for BC screening, the false positive, radiation, and overdiagnosis are still pressing issues that need to be addressed. Therefore, it is urgent to develop accessible, stable, and reliable biomarkers for non-invasive screening and diagnosis of BC. Recent studies indicated that the circulating tumor cell DNA (ctDNA), carcinoembryonic antigen (CEA), carbohydrate antigen 15-3 (CA15-3), extracellular vesicles (EV), circulating miRNAs and BRCA gene from blood, and the phospholipid, miRNAs, hypnone and hexadecane from urine, nipple aspirate fluid (NAF) and volatile organic compounds (VOCs) in exhaled gas were closely related to the early screening and diagnosis of BC. This review summarizes the advances of the above biomarkers in the early screening and diagnosis of BC.

Metastasis accounts for 90% of breast cancer deaths, where the lethality could be attributed to the poor drug accumulation at the metastatic loci. The tolerance to chemotherapy induced by breast cancer stem cells (BCSCs) and their particular redox microenvironment further aggravate the therapeutic dilemma. To be specific, therapy-resistant BCSCs can differentiate into heterogeneous tumor cells constantly, and simultaneously dynamic maintenance of redox homeostasis promote tumor cells to retro-differentiate into stem-like state in response to cytotoxic chemotherapy. Herein, we develop a specifically-designed biomimic platform employing neutrophil membrane as shell to inherit a neutrophil-like tumor-targeting capability, and anchored chemotherapeutic and BCSCs-differentiating reagents with nitroimidazole (NI) to yield two hypoxia-responsive prodrugs, which could be encapsulated into a polymeric nitroimidazole core. The platform can actively target the lung metastasis sites of triple negative breast cancer (TNBC), and release the escorted drugs upon being triggered by the hypoxia microenvironment. During the responsiveness, the differentiating agent could promote transferring BCSCs into non-BCSCs, and simultaneously the nitroimidazole moieties conjugated on the polymer and prodrugs could modulate the tumor microenvironment by depleting nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) and amplifying intracellular oxidative stress to prevent tumor cells retro-differentiation into BCSCs. In combination, the BCSCs differentiation and tumor microenvironment modulation synergistically could enhance the chemotherapeutic cytotoxicity, and remarkably suppress tumor growth and lung metastasis. Hopefully, this work can provide a new insight in to comprehensively treat TNBC and lung metastasis using a versatile platform.
