Objective:To evaluate the clinical value of sacral canal posterior wall reconstruction in the treatment of symptomatic sacral canal cysts.Methods:A retrospective cohort study was conducted.The clinical data of 80 patients with symptomatic sacral cysts who underwent surgical treatment at Beijing Friendship Hospital, Capital Medical University, between June 2018 and September 2024 were collected. There were 19 males and 61 females, with an average age of (49.0±11.3) years (ranged from 23-76 years). The patients were divided into the traditional group ( n=30) and the reconstruction group ( n=50) based on the surgical approach. The traditional group underwent the conventional surgical method without reconstruction of the posterior wall of the sacral canal, while the reconstruction group underwent posterior wall reconstruction of the sacral canal. Postoperative observations included the integrity of the sacral canal posterior wall, wound healing, and symptom improvement in both groups. Measurement data with normal distribution were expressed as mean±standard deviation( ± s). Independent samples t-test was used for comparisons of measurement data between groups. Categorical data were compared using the chi-square test or Fisher′s exact test. Ordinal data were analyzed using the Mann-Whitney U test. Pearson correlation analysis was used to assess the relationship between variables. Results:Among the 80 patients, the sacral bone integrity score in the reconstruction group was (1.42±0.49) scores, compared to (3.00±0.00) scores in the traditional group, the reconstruction group showed significantly better results ( P<0.05). Symptom improvement was also significantly different between the two groups ( P=0.038): in the traditional group, 17 patients experienced complete symptom resolution, 6 partial improvement, 7 no improvement, and 0 worsening; in the reconstruction group, 37 had complete symptom resolution, 11 partial improvement, 2 no improvement, and 0 worsening. The effective improvement rate (complete+ partial improvement) in the reconstruction group was significantly better than that in the traditional group ( P=0.012). In terms of wound healing, 76 cases healed well, 4 had delayed healing, and 0 had infections. In the traditional group, 27 healed well, 3 had delayed healing, 0 infections; in the reconstruction group, 49 healed well, 1 had delayed healing, and 0 infections. There was no significant difference in wound healing rate between the two groups ( P=0.146). A significant positive correlation was found between sacral canal posterior wall integrity and symptom improvement ( r=0.288, P=0.010). Conclusion:Sacral canal posterior wall reconstruction significantly improves postoperative anatomical integrity and clinical outcomes without increasing complications, supporting its adoption as a preferred surgical approach for symptomatic sacral canal cysts.

OBJECTIVES: This study aims to explore the current status and risk factors of oral health-related quality of life OHRQoL in patients with mental disorders and provide evidence for effective intervention measures. METHODS: A total of 397 patients diagnosed with mental illness were selected by convenience sampling, and investigation was carried out using general data questionnaire, health literacy in dentistry-14 (HeLD-14), oral health impact profile-14 (OHIP-14), and oral health status checklist. RESULTS: The total score of OHIP-14 in patients with mental disorders was 8(2, 14). The score of HeLD-14 was negatively correlated with the score of OHIP-14 (r=-0.142, P<0.01). The results of multiple linear regression showed that six variables including annual family income, schizophrenia, sweets, frequency of visits to the dentist, dental caries, and missing teeth affected OHRQoL of patients with mental disorders (P<0.05). CONCLUSIONS The poor OHRQoL of psychiatric patients is associated with many factors. Medical personnel should pay attention to their oral health problems and develop targeted oral care programs throughout the course of disease to improve oral health and related quality of life of patients.

The v-Raf murine sarcoma viral oncogene homolog B (BRAF) gene is one of the most critical proto-oncogenes and functions as a key regulator in the mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) signaling pathway. The incidence of BRAF mutations in non-small cell lung cancer (NSCLC) patients ranges from 1.5% to 5.5%, with BRAF V600 mutations accounting for approximately 30%-50% of all BRAF mutations, among which BRAF V600E represents the most prevalent mutation type. Currently, the combination of Dabrafenib and Trametinib has been recommended as first-line therapy for BRAF V600-mutant NSCLC by multiple domestic and international guidelines including National Comprehensive Cancer Network (NCCN), European Society of Medical Oncology (ESMO), and Chinese Society of Clinical Oncology (CSCO). However, there are no clear targeted treatment recommendations for BRAF non-V600 mutations. Although case reports suggest that Dabrafenib combined with Trametinib may be effective for patients with BRAF non-V600 mutations, the efficacy and safety require further validation due to limited sample size and lack of large-scale clinical trial data. This article reports a case of NSCLC with a rare BRAF insertion and deletion mutation that responded well to the treatment of Dabrafenib in combination with Trametinib, aiming to enhance clinicians' understanding of such NSCLC cases with extremely rare mutation and provide a reference for future treatment strategies.

ObjectiveTo explore the effects and mechanisms of modified Dahuang Huanglian Xiexintang on hepatic oxidative stress injury in type 2 diabetes mellitus （T2DM） rats based on the nuclear factor erythroid 2 related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） axis. MethodSix ZDF （fa/+） rats were as assigned to the blank group， and 30 ZDF （fa/fa） rats were used to induce the T2DM model by feeding a high-fat diet. After successful modeling， the rats were randomly divided into the model group， metformin group （0.18 g·kg^-1）， and low， medium， and high dose groups of modified Dahuang Huanglian Xiexintang （0.54， 1.08， 2.16 g·kg^-1）， with six rats in each group. After 12 weeks of drug intervention， the body mass， liver mass， fasting blood glucose （FBG）， and oral glucose tolerance test （OGTT） levels were measured. Serum total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL）， low-density lipoprotein cholesterol （LDL）， alanine aminotransferase （ALT）， and aspartate aminotransferase （AST） levels were detected using an automatic biochemical analyzer. The pathological changes of liver tissue were observed by hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay （ELISA） was used to detect the activity of superoxide dismutase （SOD）， reactive oxygen species （ROS）， glutathione peroxidase （GSH-Px）， and the level of malondialdehyde （MDA） in liver tissues. Immunohistochemistry was used to detect the expression of Nrf2 in the liver. Real time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the mRNA and protein expression levels of Nrf2 and HO-1 in liver tissues. ResultCompared with the normal group， the model group showed a significant increase in body mass， liver mass， and liver index （P<0.01）. Compared with the model group， the metformin group and the medium and high dose groups of modified Dahuang Huanglian Xiexintang showed a significant decrease in body weight， liver mass， and liver index （P<0.01）. Compared with the normal group， the model group showed significantly increased TC， TG， and LDL levels （P<0.01）， and significantly decreased HDL levels （P<0.01）. Compared with the model group， the metformin group and all doses of modified Dahuang Huanglian Xiexintang showed significantly reduced TC levels （P<0.01）， and significantly reduced TG levels （P<0.05）. The medium and high dose groups of modified Dahuang Huanglian Xiexintang showed significantly reduced LDL levels （P<0.05）. The metformin group and all doses of modified Dahuang Huanglian Xiexintang showed significantly increased HDL levels （P<0.05）. Compared with the normal group， the model group showed significantly increased ALT and AST activities （P<0.01）. Compared with the model group， all doses of modified Dahuang Huanglian Xiexintang and the metformin group showed significantly reduced ALT activities （P<0.05） and significantly reduced AST activities （P<0.01）. Compared with normal group， the model group showed significantly increased FBG at all time points （P<0.01）. Compared with the model group， the metformin group and all doses of modified Dahuang Huanglian Xiexintang showed significantly reduced FBG at 8， 10， 12 weeks. The OGTT results showed that compared with the normal group， the model group had significantly increased blood glucose at all time points （P<0.01）. Compared with the model group， the metformin group showed significantly reduced blood glucose at all time points （P<0.01）， and the medium and high dose groups of modified Dahuang Huanglian Xiexintang showed significantly reduced blood glucose at 90， 120 min （P<0.01）. HE pathology showed clear and regular liver cell structure in the normal group， while the model group showed disordered liver cell structure with visible fat vacuoles and a large number of deformed necrotic cells. The liver tissue structure improved in the metformin group and all doses of modified Dahuang Huanglian Xiexintang， with fewer necrotic cells. Compared with the normal group， the model group showed significantly reduced SOD and GSH-Px levels （P<0.01）， and significantly increased ROS and MDA levels （P<0.01）. Compared with the model group， the metformin group and all doses of modified Dahuang Huanglian Xiexintang showed significantly increased SOD and GSH-Px levels （P<0.01）， and significantly reduced MDA levels （P<0.01）. The medium and high dose groups of modified Dahuang Huanglian Xiexintang showed significantly reduced ROS levels （P<0.05）. Compared with the normal group， the model group showed significantly reduced Nrf2 and HO-1 mRNA expression levels （P<0.01）. Compared with the model group， the metformin group and the medium and high dose groups of modified Dahuang Huanglian Xiexintang showed significantly increased Nrf2 and HO-1 mRNA expression levels （P<0.05）. Immunohistochemistry showed that compared with the normal group， the model group had significantly reduced positive expression of Nrf2 and HO-1 （P<0.05）. Compared with the model group， the metformin group and all doses of modified Dahuang Huanglian Xiexintang showed increased positive expression of Nrf2 and HO-1， with a significant increase in brown-yellow granules around the cell nucleus （P<0.05）. Western blot results showed that compared with the normal group， the model group had significantly reduced protein expression of Nrf2 and HO-1 （P<0.01）. Compared with the model group， the metformin group and all doses of modified Dahuang Huanglian Xiexintang showed significantly increased protein expression of Nrf2 and HO-1 （P<0.01）. ConclusionModified Dahuang Huanglian Xiexintang can significantly improve the general condition and pathological changes of liver tissues in T2DM model rats. This improvement is likely achieved through ameliorating hepatic oxidative stress injury via regulating the Nrf2/HO-1 axis.

Background::Triple-negative breast cancer (TNBC) is an aggressive type of breast cancer associated with poor prognosis and limited treatment options. The androgen receptor (AR) has emerged as a potential therapeutic target for luminal androgen receptor (LAR) TNBC. However, multiple studies have claimed that anti-androgen therapy for AR-positive TNBC only has limited clinical benefits. This study aimed to investigate the role of AR in TNBC and its detailed mechanism.Methods::Immunohistochemistry and TNBC tissue sections were applied to investigate AR and nectin cell adhesion molecule 4 (NECTIN4) expression in TNBC tissues. Then, in vitro and in vivo assays were used to explore the function of AR and estrogen receptor beta (ERβ) in TNBC. Chromatin immunoprecipitation sequencing (ChIP-seq), co-immunoprecipitation (co-IP), molecular docking method, and luciferase reporter assay were performed to identify key molecules that affect the function of AR. Results::Based on the TNBC tissue array analysis, we revealed that ERβ and AR were positive in 21.92% (32/146) and 24.66% (36/146) of 146 TNBC samples, respectively, and about 13.70% (20/146) of TNBC patients were ERβ positive and AR positive. We further demonstrated the pro-tumoral effects of AR on TNBC cells, however, the oncogenic biology was significantly suppressed when ERβ transfection in LAR TNBC cell lines but not in AR-negative TNBC. Mechanistically, we identified that NECTIN4 promoter –42 bp to –28 bp was an AR response element, and that ERβ interacted with AR thus impeding the AR-mediated NECTIN4 transcription which promoted epithelial–mesenchymal transition in tumor progression. Conclusions::This study suggests that ERβ functions as a suppressor mediating the effect of AR in TNBC prognosis and cell proliferation. Therefore, our current research facilitates a better understanding of the role and mechanisms of AR in TNBC carcinogenesis.

Objective:To study the expression of microRNA (miRNA)-4783-3p in liver cancer tissue and its effect on the proliferation and migration of liver cancer Huh-7 cells.Methods:The cBioPortal database was used to analyze the expression of miR-4783-3p in liver cancer tissues and adjacent tissues. In strict accordance with the instructions of Lipofectamine? 2000 transfection kit, miR-4783-3p overexpression mimics or overexpression control mimics were transfected into Huh-7 cells respectively, namely overexpression group and control group. The proliferation of Huh-7 cells was analyzed by CCK-8 assay, and the migration of Huh-7 cells was analyzed by cell scratch method. The targeting relationship between miR-4783-3p and insulin-like growth factor binding protein 2 ( IGFBP2) mRNA was detected by dual-luciferase reporter gene assay. RT-qPCR was used to detect the expression of IGFBP2 mRNA. Western-blotting was used to detect the expression of IGFBP2 protein and EGFR-STAT3 molecular pathway proteins. Results:The expression of miR-4783-3p in liver cancer tissues was significantly lower than that in adjacent tissues ( P<0.01). Compared with the control group, the proliferation ability of Huh-7 cells in the overexpression group was significantly decreased ( P<0.05). The scratch healing rates of Huh-7 cells in the control group and the overexpression group were (67.71±9.04)% and (29.58±10.51)%, respectively, and the scratch healing rate in the overexpression group was significantly lower ( P<0.01). miR-4783-3p targeted and bound to IGFBP2 mRNA ( P<0.01). The expression of IGFBP2 mRNA in the control and overexpression groups was 5.76±1.44 and 0.99±0.47, respectively, and miR-4783-3p negatively regulated the expression of IGFBP2 mRNA ( P<0.01). Compared with the control group, the expressions of IGFBP2 protein and EGFR-STAT3 molecular pathway protein were decreased in the overexpression group. Conclusions:miR-4783-3p is lowly expressed in liver cancer tissues. miR-4783-3p can attenuate the proliferation and invasion ability of liver cancer Huh-7 cells by inducing the low expression of IGFBP2 gene.

OBJECTIVE: To investigate the clinical value of hemoglobin to serum creatinine ratio (Hb/SCr) combined with blood uric acid (SUA) in predicting in-hospital mortality after emergency percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). METHODS: The clinical data of AMI patients who underwent emergency PCI in the First Affiliated Hospital of Kangda College of Nanjing Medical University from January 2017 to December 2021 were retrospectively analyzed. The general information, underlying medical history, blood routine, liver and kidney function, blood coagulation routine, SUA and other indicators were collected from patients. The primary composite endpoint was defined as in-hospital death, including in-hospital all-cause death during PCI and 15-day post-procedure hospitalization. Multivariate Logistic regression was used to analyze factors associated with in-hospital death after emergency PCI in patients with AMI. Multivariate Logistic regression was used to analyze the independent related factors and construct a risk prediction model. The Hosmer-Lemeshow method and receiver operator characteristic curve (ROC curve) were used to test the goodness of fit and predictive effect of the model and correlates, respectively. RESULTS: A total of 1 976 patients were enrolled, 92 died in hospital and 1 884 survived. SUA was higher in the death group than that in the survival group (μmol/L: 476.88±132.04 vs. 354.87±105.31, P < 0.01), and the Hb/SCr ratio was significantly lower than that in the survival group (13.84±5.48 vs.19.20±5.74, P < 0.01). Pearson analysis showed a linear negative correlation between SUA and Hb/SCr ratio (r = -0.502, P < 0.01). Logistic regression risk model analysis finally included age [odds ratio (OR) = 0.916], Hb/SCr ratio (OR = 0.182), white blood cell count (WBC, OR = 2.733), C-reactive protein (CRP, OR = 3.611), SUA (OR = 4.667), blood glucose (Glu, OR = 2.726), homocysteine (Hcy, OR = 2.688) 7 factors to construct a risk prediction model, which were independent correlation factors for in-hospital death in AMI patients after emergency PCI (all P < 0.05). Hosmer-Lemeshow test verified the fitting effect of the model, and the result showed P = 0.447. The area under the ROC curve (AUC) of the model for predicting in-hospital death in AMI patients after emergency PCI was 0.764 [95% confidence interval (95%CI) was 0.712-0.816, P = 0.001]. When the cut-off value was 0.565 8, the sensitivity was 70.7%, the specificity was 70.2%, and the Yoden index was 0.410. When Hb/SCr ratio+SUA, SUA, Hb/SCr ratio, Hb and SCr were used to predict in-hospital death in AMI patients after emergency PCI, the AUC of Hb/SCr ratio+SUA was the largest, which was 0.810. When the optimal cut-off value was -0.847, the sensitivity was 77.7%, the specificity was 74.5%, and the Youden index was 0.522. CONCLUSIONS Age, SUA, Hb/SCr ratio, WBC, CRP, Glu, and Hcy are independent risk factors for in-hospital death after emergency PCI in AMI patients. The lower the Hb/SCr ratio and the higher the SUA at admission, the higher the risk of in-hospital death after emergency PCI in AMI patients. Hb/SCr ratio combined with SUA has a higher predictive value for in-hospital death after emergency PCI in AMI patients than single index, which is helpful for early identification of high-risk patients.
