Objective:To analyze the characteristics of BRCA gene mutations in patients with ovarian epithelial carcinoma and fallopian tube carcinoma, and to investigate the impact of mutations in the functional domains of the BRCA genes on the prognosis of patients.Methods:This research collected a total of 273 patients diagnosed with primary ovarian epithelial carcinoma or fallopian tube carcinoma by pathological examination at the First Affiliated Hospital of Nanjing Medical University between January 2009 and December 2023.Data on their BRCA gene mutation status, clinicopathological data, and follow-up information were collected. A retrospective analysis was conducted to evaluate the association between BRCA gene mutations and patients' prognosis, including progression free survival (PFS) and overall survival (OS) time.Results:Among the 273 patients with ovarian or fallopian tube carcinoma, 101 cases (37.0%, 101/273) were positive for BRCA gene mutations (BRCA-positive group), while 172 cases (63.0%, 172/273) were negative for BRCA gene mutations (BRCA-negative group). (1) Clinicopathological characteristics: compared with the BRCA-negative group, the BRCA-positive group had a younger age at diagnosis, lower proportion of postmenopausal status, and lower recurrence rate (all P<0.05). Additionally, the BRCA-positive group showed a higher prevalence of family history of gynecological malignancies and a higher rate of no visible residual disease (R0) resection, all with statistical significance (all P<0.05). (2) Characteristics of BRCA gene mutations: among the 101 BRCA-positive patients, 74 cases (27.1%, 74/273) had BRCA1 gene mutations, 26 cases (9.5%, 26/273) had BRCA2 gene mutations, and 1 case (0.4%, 1/273) had indeterminate mutation records. According to the American College of Medical Genetics and Genomics (ACMG) 2015 guideline, mutations of uncertain significance accounted for 22.8% (23/101), likely pathogenic mutations accounted for 10.9% (11/101), and pathogenic mutations accounted for 59.4% (60/101), with 5.9% (6/101) unclassifiable. BRCA1 and BRCA2 genes have three (RING, DBD, BRCT) and two (RAD51-BD, DBD) major functional domains, respectively. Among the 89 BRCA-positive patients with detailed domain mutation data, the overall domain mutation rate was 40.4% (36/89), distributed as follows: DBD 14.6% (13/89), BRCT 12.4% (11/89), RING 4.5% (4/89), and RAD51-BD 9.0% (8/89). (3) Association between BRCA gene functional domain mutations and prognosis: among 77 patients with advanced stage (Ⅲ-Ⅳ) ovarian epithelial carcinoma in the BRCA-positive group with functional domain mutation data, the median PFS time was significantly longer in the 31 patients with domain mutations compared to the 46 patients with non-domain mutations (not reached during the follow-up period, vs 26.0 months; P=0.035). However, there was no significant difference in median OS time between the two groups (not reached during the follow-up period, vs 67.0 months; P=0.513). Median PFS time was longer in 13 patients with mutations in the DBD functional domain than that in 64 patients with mutations outside the DBD functional domain (not reached during the follow-up period, vs 28.0 months; P=0.042), whereas there was no significant difference in the comparison of median OS time between the two groups (not reached during the follow-up period, vs 67.0 months; P=0.321). (4) Association between BRCA gene functional domain mutations and efficacy of poly adenosine diphosphate ribose polymerase inhibitor (PARPi) maintenance therapy: among 51 advanced stage ovarian epithelial carcinoma patients who received PARPi maintenance therapy in the BRCA-positive group, 20 patients with domain mutations demonstrated significantly longer median PFS time compared to 31 patients with non-domain mutations (not reached during the follow-up period, vs 31.0 months; P=0.039). However, no significant difference was observed in median OS time between the two groups (not reached during the follow-up period, vs 53.0 months; P=0.178). PARPi maintenance therapy was more effective in the 9 patients with mutations in the DBD functional domain than that in the 42 patients with mutations located outside the DBD structural domain, with significant differences observed in both median PFS time (both not reached during the follow-up period; P=0.007) and median OS time (both not reached during the follow-up period; P=0.037). In contrast, patients with mutations in the BRCT or RAD51-BD domains showed no significant differences in either median PFS or OS time compared to patients with mutations outside these domains (all P>0.05). Conclusions:Patients with ovarian epithelial carcinoma and fallopian tube carcinoma who harbor BRCA functional domain mutations exhibit significantly longer median PFS time compared to those with non-domain mutations. Moreover, among patients received PARPi maintenance therapy, those with mutations in the DBD domain have a better median PFS and OS time benefit.

Objective To investigate the neural basis of glucagon-like peptide-1(GLP-1)in regulating glucose homeostasis and elucidate the molecular mechanisms.Methods Male Glp1r-IRES-Cre,Glp1r-KO,and wild-type mice were used in this study.Fiber photometry was employed to record Ca2+signals of neurons in ventromedial hypothalamus(VMH)and patch-clamp was used to analyze electrophysiological properties of GLP-1 receptor-positive(GLP-1RVMH)neurons.Viral stereotaxic injections,chemogenetics,plasma hormone assays,and routine glucose metabolism assessments were combined to determine the regulatory role of GLP-1RVMH neurons in glucose homeostasis.Tissue and cell mitochondrial respiratory function assays,transmission electron microscopy,and conventional molecular biology methods were used to explore the mechanism by which GLP-1R agonists regulate glucose homeostasis.Results When the glucose concentration decreased from 5.0 mmol/L to 0.5 mmol/L,the action potential frequency of GLP-1RVMH neuron decreased significantly[(4.51±0.80)Hz vs.(1.43±0.51)Hz,P<0.01].Activation of GLP-1RVMH neuron significantly enhanced insulin secretion[(7.60±0.56)μU/mL vs.(11.34±0.93)μU/mL,P<0.01],while inhibition of these neuronal activities impaired the hypoglycemic efficiency of GLP-1 agonists[(32.03%±0.91%)vs.(25.77%±1.09%),P<0.001)].Mechanistically,GLP-1 regulated glucose homeostasis through Drp1 phosphorylation-mediated mitochondrial fission and improved mitochondrial energy metabolism.Conclusion GLP-1RVMH neurons are a class of glucose-excited neurons,and which activated directly promotes secretion of insulin.The hypoglycemic effect of GLP-1R agonists depend on the neuronal activity of GLP-1RVMH.

Calciphylaxis, also known as calcific uremic arteriopathy (CUA), is a rare arteriosclerosis disease characterized by skin ischemia and necrosis with severe pain, which occurs in end-stage renal disease patients. The efficacy of sodium thiosulfate (STS) in CUA has been widely verified and affirmed. However, there is no unified standard for the use of STS at home and abroad.This article introduced a case of severe CUA patient who had achieved good results under different STS usage treatments, and summarized the different STS usage treatments for CUA combined with literature.

Objective To analyze the influence of anxiety and depression on postoperative recovery of patients with acute coronary syndrome(ACS),and to analyze the relationship with neutrophil to lymphocyte ratio(NLR),lymphocyte to monocyte ratio(LMR)and platelet-to-lymphocyte ratio(PLR).Methods A total of 108 ACS patients undergoing surgical treatment in Hainan Provincial Anning Hospital from March 2022 to March 2024 were retrospectively recruited.According to their scores of Hamilton anxiety scale and Hamilton depression scale,they were divided into an anxiety and depression group(34 cases)and a non-anxiety and depression group(74 cases).The quality of life at 1 month after surgery and serum levels of NLR,LMR and PLR at 3 d after surgery were compared between groups.Spearman correlation analysis was performed to analyze the correlation between serum NLR,LMR and PLR and anxiety as well as depression in the ACS patients.Binary logistic regression analysis was used to construct an evaluation model with NLR,LMR and PLR as variables.Receiver operating characteristic(ROC)curve was plotted to analyze the value of serum NLR,LMR and PLR in evaluating anxiety and depression.Results At 1 month after surgery,the scores of dimensions of Short-Form 36 Questionnaire(SF-36)were significantly lower in the anxiety and depression group than the non-anxiety and depression group(P＜0.01).The levels of serum NLR and PLR at 3 d post-operatively were obviously higher while that of LMR was notably lower in the anxiety and depression group than the non-anxiety and depression group(P＜0.01).Spearman correlation analysis indicated that serum NLR and PLR levels(r=0.500,P=0.000;r=0.215,P=0.026)were positively correlated,and LMR level(r=-0.474,P=0.000)was negatively correlated with co-occurrence of anxiety and depression in the ACS patients.Binary logistic regression analysis suggested that NLR,LMR and PLR were high risk factors for anxiety and depression in ACS patients(OR=6.867,95％CI:2.792-16.887,P=0.000;OR=0.180,95％CI:0.078-0.419,P=0.000;OR=1.285,95％CI:1.038-1.591,P=0.032).ROC curve analysis showed that the AUC value of the three indicators combined together in evaluating anxiety and depression in the ACS patients was 0.900(95％CI:0.827-0.949,P=0.000),with a sensitivity of 73.53％and a specificity of 95.95％.The efficiency of combined evalu-ation was superior to that of each indicator.Conclusion Anxiety and depression can affect the postoperative recovery and serum NLR,LMR and PLR in ACS patients.Early combined detection of the three indicators can provide certain value for whether ACS patients are complicated with anxiety and depression.
