Breast cancer (BC) ranks first in the incidence rate of female malignant tumor, the notable features of which include high invasive behavior, high malignant degree and poor prognosis. Resveratrol, a plant antioxidant, has been identified as a potential therapeutic agent for the occurrence and progress of BC. This article explores the mechanism of resveratrol intervention in BC by evaluating several in vitro and in vivo studies. It was found that resveratrol can weaken the proliferation and survival ability of BC cells, suppress their growth, metastasis, and invasion, and reverse their resistance to adriamycin by promoting cell apoptosis, regulating autophagy, inhibiting glycolysis and regulating the tumor microenvironment, expressions of matrix metalloproteinases, epithelial-mesenchymal transition and drug-resistant proteins, etc. The limited number of clinical trial studies on resveratrol, mainly focusing on prevention effect of it on breast cancer, may be one of the reasons that affect the comprehensive evaluation of the anti-cancer efficacy of resveratrol.

Objective:To explore the risk factors of oral-mucosal pressure injury (OMPI) in patients with tracheal intubation in ICU and to establish a nomogram model.Methods:Using the convenient sampling method, a total of 640 patients with oral tracheal intubation admitted to ICU of the First Affiliated Hospital of Xinjiang Medical University from January to May 2023 were selected as the research objects. They were divided into the occurrence group ( n=286) and the non-occurrence group ( n=354) according to whether OMPI occurred or not. Binomial Logistic regression analysis was used to explore the risk factors for OMPI in patients with tracheal intubation in ICU. A risk nomogram model was created based on independent risk factors, and internal verification was conducted by Bootstrap repeated sampling method. Results:OMPI occurred in 286 of 640 ICU patients with tracheal intubation. Binomial Logistic regression analysis showed that high APACHEⅡ score, modified Beck oral score greater than or equal to 11 points, use of sedative drugs, prone ventilation, long retention time of tracheal catheter, low oxygenation index less than 200 mmHg (1 mmHg=0.133 kPa) and tracheal catheter fixation frequency of 1 time /24 h were the risk factors for OMPI in patients with tracheal intubation in ICU ( P<0.05). A risk nomogram model for OMPI in patients with tracheal intubation in ICU was established based on independent risk factors. The results showed that the predictive performance (area under the receiver operating characteristic curve of subjects was 0.918, 95% confidence interval was 0.897 to 0.938) and calibration (χ 2 value of 4.647, P=0.795) of the risk nomogram model for OMPI in patients with tracheal intubation in ICU were good. When the threshold probability was 0 to 1, the decision curve showed that the model had good clinical effectiveness. Conclusions:The OMPI risk nomogram model of tracheal intubation patients in ICU established in this study has good calibration and differentiation, which can be used as an effective tool for screening high-risk patients.

ObjectiveTo investigate the effect and underlying molecular mechanism of astragaloside-Ⅳ (AS-Ⅳ) on autophagy and apoptosis of nasopharyngeal carcinoma cells. MethodIn experiments in vitro, the effect of AS-Ⅳ on the autophagy of nasopharyngeal carcinoma cells was observed by monodansylcadaverine (MDC) staining and transmission electron microscopy (TEM). In experiments in vivo, immunofluorescence (IF) and Western blot were used to detect the changes in autophagy and apoptosis and the expression of key proteins in the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway after the establishment of a xenograft tumor model in nude mice. ResultAfter 5-8F cells were treated with AS-Ⅳ of different doses (5, 10, 20 μmol·L-1), the fluorescence intensity of autophagy in AS-Ⅳ groups significantly increased as compared with that in the blank group. The fluorescence expression of autophagy in AS-Ⅳ groups was the strongest after intervention for 24 hours, and the fluorescence expression in the 10 μmol·L-1 AS-Ⅳ group was the most obvious. The autophagy activator rapamycin (RAPA) induced more autophagosomes in 5-8F cells under the transmission electron microscope, and 3-methyladenine (3-MA), an autophagy inhibitor, did not induce autophagosome formation in 5-8F cells under the transmission electron microscope as compared with the results in the blank group. In the 10 μmol·L-1 AS-Ⅳ group, the intracellular structure and cell membrane were intact and clear, and autophagosome formation was observed. Compared with the blank group, the AS-Ⅳ groups showed inhibited tumor volume (P<0.05, P<0.01), potentiated fluorescence signals of microtubule-associated protein l light chain 3 type Ⅱ/microtubule-associated protein l light chain 3 type Ⅰ (LC3 Ⅱ/Ⅰ) and cleaved Caspase-3 (P<0.05, P<0.01), increased expression levels of the mammalian homolog of yeast ATG6 (Beclin-1), LC3 Ⅱ/Ⅰ, cleaved Caspase-3, and cleaved PARP (P<0.05, P<0.01), down-regulated expression of ubiquitin-binding protein (p62) (P<0.05, P<0.01), and reduced protein expression levels of phosphorylated PI3K (p-PI3K), phosphorylated Akt (p-Akt), and phosphorylated mTOR (p-mTOR) (P<0.05, P<0.01). ConclusionAS-Ⅳ can induce autophagy and apoptosis of nasopharyngeal carcinoma cells, and the mechanism is presumably attributed to the activation of the PI3K/Akt/mTOR signaling pathway.

【Objective】 To explore a new treatment of primary bilateral macronodular adrenal hyperplasia (PBMAH) and its efficacy. 【Methods】 Clinical data of 20 PBMAH patients treated in our hospital during Mar.2010 and Apr.2021 were retrospectively analyzed. All patients underwent laparoscopic subcutaneous displacement of vascularized adrenal. The clinical symptoms, plasma free cortisol, adrenocorticotrophic hormone (ACTH), and 24 h urinary free cortisol were regularly monitored after surgery. 【Results】 Of all 20 patients, 19 were followed up for 18 to 120 months (median 60 months). Three months after surgery, reexamination showed 1 patient had decreased plasma free cortisol and increased ACTH, but had no symptoms of low corticosteroids. After another 3 months, the plasma free cortisol and ACTH returned to normal. After 4 to 48 months, the parameters recovered in all patients and the clinical symptoms disappeared. 【Conclusion】 Laparoscopic vascularized adrenal displacement is a new and effective method for the treatment of PBMAH. It can alleviate the Cushing syndrome with no obvious adverse reactions.

Objective:To analyze the symmetry of different reference planes in the surgical simulation design of patients with protrusive jaw deformity with high and low eyes.Methods:Fifteen patients with partial jaw deformity were selected from January 2019 to June 2020, including 3 males and 12 females, aged 18-26 years, with average 23.78 years. Inclusion criteria were that the patients, aged more than 18 years, were diagnosed as protrusive jaw deformity with maxillary occlusal plane tilt and high and low eyes by clinical and imaging analysis. Three different 3D reference plane systems were established by different modeling methods. The distance between the landmarks of soft and hard tissues and the median sagittal plane was measured. The symmetry of skull was qualitatively analyzed by mirror image technique. The difference of three reference planes in surgical simulation symmetry of patients with protrusion jaw and high and low eyes was evaluated by one-way ANOVA.Results:Qualitative analysis showed that in the three measurement planes, the symmetry of the third reference plane was the best, and the symmetry of the second and the first was poor. Quantitative analysis showed that in measurement index of hard tissue, there was statistical difference between the distance of each landmark in the reference plane established by Method 3 and Method 1, Method 2 [(1.65±1.19) mm; (3.37±1.58) mm; (3.26±2.36) mm, P<0.05], but there was no statistical difference between Method 1 and Method 2 (P > 0.05). The measurement result of soft tissue was consistent with that of hard tissue, and the distance of each landmark in Method 3 from the median sagittal plane was very small, and the mean error was less than 0.5 mm, which was consistent with the clinical results. Conclusions:Digital model surgery technology can assist orthognathic surgeons in the design and prediction of surgical scheme, especially for patients with special partial jaw deformity.

Objective:To analyze the influencing factors of the medical insurance balance of hospitalization expenses for gastric cancer surgery patients under DRG payment, for reference for promoting the reform of DRG payment in public hospitals and controlling hospitalization expenses reasonably.Methods:The gastric cancer patients enrolled in the gastroenterology department of a tertiary comprehensive hospital from January to July 2022 were selected as the research subjects. The indicators such as patient age, medical insurance balance, hospitalization expenses and their composition were extracted from the hospital information management system and the medical insurance settlement system a certain city. Descriptive analysis was conducted for all data, and stepwise multiple linear regression was used to analyze the influencing factors of patients′ medical insurance balance. Monte Carlo simulation method was used to simulate different combination scenarios of various influencing factors to analyze the probability of medical insurance balance.Results:A total of 205 patients were contained, including 117 in the medical insurance balance group and 88 in the loss group. The difference in hospitalization expenses and medical insurance balance between the two groups of patients were statistically significant ( P<0.05). The intervention of medical insurance specialists, correct DRG enrollment, parenteral nutrition preparation costs, anti infective drug costs, examination costs, and consumables costs were the influencing factors of patient medical insurance balance ( P<0.05). Through Monte Carlo simulation verification, patients with different cost parenteral nutrition preparations, or different anti infective drug schemes had the higher probability of medical insurance balance in the scenario where the medical insurance commissioner intervenes and the DRG enrollment was correct. Conclusions:The hospital adopted interventions from medical insurance specialists to ensure the correct DRG enrollment of patients, accurate use of parenteral nutrition and anti infective drugs, and reasonable control the cost of examinations and consumables, which could increase the probability of medical insurance balance for gastric cancer surgery patients. In the future, hospitals should further promote the procurement of drug consumables in bulk, reduce unnecessary examinations, develop standardized perioperative nutritional interventions and anti infection treatment pathways, ensure the accuracy of DRG enrollment, optimize clinical diagnosis and treatment pathways to improve the efficiency of medical insurance fund utilization and provide high-quality medical services for patients.
