Objective: To establish a prediction model for high-risk cardiovascular disease (CVD) among residents aged 35 to 75 years, so as to provide the basis for improving CVD prevention and control measures. Methods: Permanent residents aged 35 to 75 years were selected from Dongcheng District, Beijing Municipality using the stratified random sampling method from 2018 to 2023. Demographic information, lifestyle, waist circumference and blood biochemical indicators were collected through questionnaire surveys, physical examinations and laboratory tests. Influencing factors for high-risk CVD among residents aged 35 to 75 years were identified using a multivariable logistic regression model, and a prediction model for high-risk CVD was established. The predictive effect was evaluated using the receiver operating characteristic (ROC) curve. Results: A total of 6 968 individuals were surveyed, including 2 821 males (40.49%) and 4 147 females (59.51%), and had a mean age of (59.92±9.33) years. There were 1 155 high-risk CVD population, with a detection rate of 16.58%. Multivariable logistic regression analysis showed that gender, age, smoking, central obesity, systolic blood pressure, fasting blood glucose, triglyceride and low-density lipoprotein cholesterol were influencing factors for high-risk CVD among residents aged 35 to 75 years (all P<0.05). The area under the ROC curve of the established prediction model was 0.849 (95%CI: 0.834-0.863), with a sensitivity of 0.693 and a specificity of 0.863, indicating good discrimination. Conclusion The model constructed by eight factors including demographic characteristics, lifestyle and blood biochemical indicators has good predictive value for high-risk CVD among residents aged 35 to 75 years.

Peyronie's disease (PD) is a disorder characterized by fibrous plaque formation in the penile tissue that leads to curvature and complications in advanced stages. In this study, we aimed to compare four injectable induction agents for the establishment of a robust rat model of PD: transforming growth factor-β1 (TGF-β1), fibrin, sodium tetradecyl sulfate (STS) combined with TGF-β1, and polidocanol (POL) combined with TGF-β1. The results showed that injection of TGF-β1 or fibrin into the tunica albuginea induced pathological endpoints without causing penile curvature. The STS + TGF-β1 combination resulted in both histological and morphological alterations, but with a high incidence of localized necrosis that led to animal death. The POL + TGF-β1 combination produced pathological changes and curvature comparable to STS + TGF-β1 and led to fewer complications. In conclusion, fibrin, STS + TGF-β1, and POL + TGF-β1 all induced PD with a certain degree of penile curvature and histological fibrosis in rats. The POL + TGF-β1 combination offered comparatively greater safety and clinical relevance and may have the greatest potential for PD research using model rats.

OBJECTIVE To investigate the relationship between azimuth direction,angular intervals,and the accuracy of azimuthal sound source localization.METHODS Fifteen young subjects with normal hearing were tested using nine azimuth settings.The test results were presented as root mean square error and percentage confusion.RESULTS The confusion rate under high-frequency narrowband noise was significantly higher than that under broadband noise and three-syllable words.In the frontal direction,statistically significant differences were observed between the 20° and 10° intervals,as well as between the 20° and 15° intervals(P<0.05),but no significant difference was found between the 10° and 15° intervals(P>0.05).In the lateral and rear directions,statistically significant differences were found between the 30° and 15° intervals,as well as between the 30° and 20° intervals(P<0.05),but no significant difference was found between the 15° and 20° intervals(P>0.05).Statistically significant differences were observed between the frontal direction and both the lateral and rear directions(P<0.05),but no significant difference was found between the lateral and rear directions(P>0.05).CONCLUSION Using stimuli that contain broader bandwidth cues can more accurately reflect the subject's horizontal localization ability.For source azimuth identification tests using broadband noise and three-syllable words,it is recommended to use a 15° interval in the frontal direction,and a 20° interval in the lateral and rear directions.The frontal and lateral directions can be preferred for testing.

Objective To determine the median effective dose(ED50)of remimazolam for preoperative sedation in pediatric patients aged 1-6 years using the modified Dixon sequential method.Methods This is a prospective clinical study.Pediatric patients scheduled for elective short surgery(surgery time≤1 h)under general anesthesia from January to July 2023 were selected.Inclusion criteria were age 1-6 years,an ASA physical status Ⅰ-Ⅱ and the preoperative parent separation anxiety scale(PSAS)score≥3 points.Remimazolam was administered intravenously preoperatively,and its sedative effect was assessed.The modified Dixon sequential method was used to determine the ED50 of remimazolam,with the initial dose set at 0.10 mg/kg and the dose increment set at 0.02 mg/kg.Sedation was considered successful(positive,included in positive group)if the child with sedation score≥2 points,preoperative PSAS score<3 points,and the mask acceptance score of 4 points during anesthesia induction.If any criterion was not met,sedation was considered failure(negative,included in negative group),and the next patient's dosage was increased by 0.02 mg/kg based on the previous patient's dosage.The test was completed after 7 consecutive positive and negative turning points appeared alternately.Probabilistic unit regression analysis was used to determine the ED50,ED95 and the corresponding 95%confidence interval(CI)of remimazolam for preoperative sedation.Postoperative recovery time and adverse events such as airway spasm,respiratory depression,hypotension,nausea and vomiting during anesthesia were recorded.Results A total of 23 pediatric patients were included,with 13 in positive group and 10 in negative group.There were no statistically significant differences in mean arterial pressure,pulse oxygen saturation or heart rate before and after sedation(P>0.05).Compared with negative group,positive group showed a significant reduction in preoperative parent separation anxiety and an increase in mask acceptance during anesthesia(P<0.05).There was no significant difference in sedation score and anesthesia awakening time between two groups(P>0.05).The ED50 of remimazolam for preoperative sedation in pediatric patients aged 1-6 years was 0.051 mg/kg(95%CI 0.033-0.065 mg/kg),and the ED95 was 0.077 mg/kg(95%CI 0.064-0.161 mg/kg).No adverse events such as airway spasm,respiratory depression,hypotension,nausea and vomiting occurred during anesthesia in any of pediatric patients.Conclusion The ED50 of intravenous administration of remimazolam for preoperative sedation in pediatric patients aged 1-6 years is 0.051 mg/kg(95%CI 0.033-0.065 mg/kg).

Objective To compare the hemodynamic effects of anesthesia induction with remimazolam tosylate and etomidate in elderly frail patients.Methods This study was a single-center,prospective,randomized,single-blind trial.From January to April 2024,96 elderly frail patients undergoing elective surgery in Fuyang People's Hospital were recruited.After excluding 6 cases(3 refused to participate,1 had tracheal intubation time＞30 s,and 2 had missing data),90 patients were finally included.They were randomly divided into remimazolam tosylate group(intravenous injection of 0.2 mg/kg remimazolam tosylate for anesthesia induction,n=45)and etomidate group(intravenous injection of 0.3 mg/kg etomidate for anesthesia induction,n=45)by the random number table method.The area under the curve for mean arterial pressure(MAP)below or above baseline values(AUCMAP-and AUCMAP+),the heart rate(HR)below or above baseline values by 10％(AUCHR-and AUCHR+)within 10 minutes of anesthesia induction,the time to loss of consciousness,the time from the start of anesthesia induction to a bispectral index(BIS)＜60,the incidence of drug-related adverse reactions,the incidence of cardiovascular adverse events,and the usage of vasoactive drug administrations were compared between the two groups.Results Compared with the etomidate group,the AUCMAP-(145.10±35.75 vs.178.52±39.78)and AUCHR-[43.20(26.58,56.35)vs.54.99(43.01,65.85)]in remimazolam tosylate group were significantly reduced(P＜0.001,P=0.001).The time to loss of consciousness and the time from the start of anesthesia induction to BIS＜60 were prolonged(P＜0.001).The incidence of drug-related adverse reactions was significantly decreased(P＜0.05),and the number of norepinephrine administrations was significantly reduced(P＜0.05)in remimazolam tosylate group.However,there were no statistically significant differences in AUCMAP+,AUCHR+,the incidence of cardiovascular adverse events,and the usages of atropine,urapidil,and esmolol between the two groups(P＞0.05).Conclusion The use of remimazolam tosylate during anesthesia induction in elderly frail patients can provide more stable hemodynamic parameters and results in fewer adverse reactions than etomidate.

Patient-reported outcome (PRO) has been paid increasing attention in lung cancer surgery. It has gradually become an important outcome indicator in clinical research of lung cancer surgery and an important tool for symptom management. Commonly used lung cancer-specific PRO measurement tools include: Lung Cancer Symptom Scale, European Organization for Research and Treatment of Cancer-Core Quality of Life Questionnaire and Lung Cancer module, Functional Assessment of Cancer Therapy-Lung, MD Anderson Symptom Inventory-Lung Cancer module, Postoperative Symptom Scale for Lung Cancer Patients, and Perioperative Symptom Assessment for Lung Surgery. The application of lung cancer-specific scales lacks authoritative implementation norms in the field of lung cancer surgery in terms of scale selection, data collection, and outcome application. This review aimed to analyze the current status of application of PRO scales in lung cancer surgery.

Objective To observe the clinical effect of Tongyuan Acupuncture combined with Modified Linggui Zhugan Decoction in the treatment of polycystic ovary syndrome(PCOS)with spleen deficiency and phlegm-damp syndrome.Methods A total of 86 patients with PCOS of spleen deficiency and phlegm-damp type were randomly divided into observation group and control group,43 cases in each group.The control group was treated with Metformin Hydrochloride Tablets combined with Ethinylestradiol and Cyproterone Acetate Tablets.The observation group was treated with Tongyuan Acupuncture combined with Modified Linggui Zhugan Decoction on the basis of the treatment of the control group.Both groups were treated for three consecutive months.After three months of treatment,the clinical efficacy of the two groups was evaluated.The changes of sex hormone indexes estradiol(E2),testosterone(T),luteinizing hormone(LH),follicle stimulating hormone(FSH)and prolactin(PRL)expression levels were observed before and after treatment in the two groups.The changes of glucose metabolism levels including insulin resistance index(HOMA-IR),fasting insulin(FINS)and fasting blood glucose(FPG)expression levels were compared before and after treatment between the two groups.Results(1)The total effective rate was 90.70%(39/43)in the observation group and 74.42%(32/43)in the control group.The curative effect of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,HOMA-IR,FINS and FPG in the two groups were significantly improved(P＜0.05),and the improvement of HOMA-IR,FINS and FPG in the observation group was superior to that in the control group,the difference being significant(P＜0.05).(3)After treatment,the levels of E2,T,LH,FSH and PRL in the two groups were significantly improved(P＜0.05),and the levels of E2,T,LH,FSH and PRL in the observation group were significantly superior to those in the control group,the differences were statistically significant(P＜0.05).Conclusion Tongyuan Acupuncture combined with Modified Linggui Zhugan Decoction in the treatment of spleen deficiency and phlegm-damp type of PCOS can effectively improve the sex hormone level of patients and regulate the glucose metabolism of patients.The clinical effect is significant.

Purpose::Vibrio vulnificus ( V. Vulnificus) infection is characterized by rapid onset, aggressive progression, and challenging treatment. Bacterial resistance poses a significant challenge for clinical anti-infection treatment and is thus the subject of research. Enhancing host infection tolerance represents a novel infection prevention strategy to improve patient survival. Our team initially identified cytochrome P4501A1 (CYP1A1) as an important target owing to its negative modulation of the body's infection tolerance. This study explored the superior effects of the CYP1A1 inhibitor bergamottin compared to antibiotic combination therapy on the survival of mice infected with multidrug-resistant V. Vulnificus and the protection of their vital organs. Methods::An increasing concentration gradient method was used to induce multidrug-resistant V. Vulnificus development. We established a lethal infection model in C57BL/6J male mice and evaluated the effect of bergamottin on mouse survival. A mild infection model was established in C57BL/6J male mice, and the serum levels of creatinine, urea nitrogen, aspartate aminotransferase, and alanine aminotransferase were determined using enzyme-linked immunosorbent assay to evaluate the effect of bergamottin on liver and kidney function. The morphological changes induced in the presence of bergamottin in mouse organs were evaluated by hematoxylin and eosin staining of liver and kidney tissues. The bacterial growth curve and organ load determination were used to evaluate whether bergamottin has a direct antibacterial effect on multidrug-resistant V. Vulnificus. Quantification of inflammatory factors in serum by enzyme-linked immunosorbent assay and the expression levels of inflammatory factors in liver and kidney tissues by real-time quantitative polymerase chain reaction were performed to evaluate the effect of bergamottin on inflammatory factor levels. Western blot analysis of IκBα, phosphorylated IκBα, p65, and phosphorylated p65 protein expression in liver and kidney tissues and in human hepatocellular carcinomas-2 and human kidney-2 cell lines was used to evaluate the effect of bergamottin on the nuclear factor kappa-B signaling pathway. One-way ANOVA and Kaplan-Meier analysis were used for statistical analysis. Results::In mice infected with multidrug-resistant V. Vulnificus, bergamottin prolonged survival ( p = 0.014), reduced the serum creatinine ( p = 0.002), urea nitrogen ( p = 0.030), aspartate aminotransferase ( p = 0.029), and alanine aminotransferase ( p = 0.003) levels, and protected the cellular morphology of liver and kidney tissues. Bergamottin inhibited interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α expression in serum (IL-1β: p = 0.010, IL-6: p = 0.029, TNF-α: p = 0.025) and inhibited the protein expression of the inflammatory factors IL-1β, IL-6, TNF-α in liver (IL-1β: p = 0.010, IL-6: p = 0.011, TNF-α: p = 0.037) and kidney (IL-1β: p = 0.016, IL-6: p = 0.011, TNF-α: p = 0.008) tissues. Bergamottin did not affect the proliferation of multidrug-resistant V. Vulnificus or the bacterial load in the mouse peritoneal lavage fluid ( p = 0.225), liver ( p = 0.186), or kidney ( p = 0.637). Conclusion::Bergamottin enhances the tolerance of mice to multidrug-resistant V. Vulnificus infection. This study can serve as a reference and guide the development of novel clinical treatment strategies for V. Vulnificus.
