The sonographic features of male breast lesions, which underwent ultrasound examination in our hospital for the past 10 years, were retrospectively analyzed. Sonographic features of these lesions were standardized as BI RADS image lexicon. The differences in ultrasonic malignant signs were assessed between the benign and the malig nant diseases. Between the two groups, incomplete boundary was statistically different. The specificity was above 95% within the two groups in terms of speculated margin, echogenic halo, calcification, axillary lymphadenopathy, thickening of skin and eccentric of mass to the nipple. High-frequency sonographic examination has a high level of differential diagnosis for male breast lesions.

The clinical pathological features, treatment and prognosis were discussed in the literature, and compared with the biological characteristics of young (under 35 years old) breast cancer patients, providing a reference for the clinical individualized treatment of the disease.

Objective:To monitor the effects of intervention and management on the quality of life and the incidence of cardiovascular events in patients with chronic heart failure in the community setting.Methods:Based on questionnaire data, 200 patients with chronic heart failure in the community were randomly divided into an observation group and a control group, with 100 cases in each group.The control group was followed up for routine health information collection at home, while the observation group received standardized community intervention for patients with chronic heart failure.The awareness rate of heart failure, rate of patients receiving drug treatment, rate of standardized drug utilization, cardiac function, satisfaction with quality of life and incidence of cardiovascular events were compared between the two groups.Results:Scientific intervention for community-dwelling patients with chronic heart failure was able to significantly improve standardized drug usage and quality of life( P<0.05).Compared with the control group, patients in the observation group showed a significantly lower probability of cardiovascular events and more favorable results measured with parameters such as blood pressure, blood glucose and heart rate after intervention.Especially noteworthy was that the effective control rate of blood pressure in the observation group reached 72.4%, which was much higher than 45.9% in the control group( χ2=14.543, P<0.05), the effective control rate of blood glucose in the observation group reached 69.4%, which was much higher than 32.7% in the control group( χ2=12.588, P<0.05), and the effective control rate of heart rate in the observation group(80.6%)was much higher than in the control group(53.1%)( χ2=13.137, P<0.05).The observation group also had better results than the control group in quitting smoking, eating a low-salt, low-fat diet, and regularly measuring blood pressure, blood glucose and body fat percentage.The MNLF score in the control group(31.21±3.01)was higher than that in the observation group(22.66±2.87), and the difference was statistically significant( t=7.26, P<0.05).The LiHFe score in the control group(39.85±6.09)was lower than that in the observation group(71.36±4.32), and the difference was statistically significant( t=18.44, P<0.05).The observation group had lower readmission frequency(46.9% vs.29.6%)and incidence of cardiovascular events(56.1% vs.31.6%)than the control group and the difference was statistically significant( χ2=12.64, 15.01, both P<0.05). Conclusions:The establishment of community intervention and management for patients with chronic heart failure can significantly improve the awareness rate of heart failure, rate of drug treatment, rate of standardized drug usage, self-management ability and quality of life, and reduce the incidence of cardiovascular events.The practice should be promoted in communities.

Objective:To explore the association between non-thyroid illness syndrome(NTIS)and pre-sarcopenia in the elderly.Methods:In the retrospective study, a total of 219 patients aged 60-85 years in Department of Geriatrics, Sir Run Run Hospital, Nanjing Medical University from April 2018 to March 2021, included 60 patients with NTIS and 159 patients without NTIS.Clinical data, laboratory results and body composition data were collected.Pre-sarcopenia was diagnosed based on human composition determination data and diagnostic criteria of pre-sarcopenia.Logistic regression analysis, Pearson's correlation analysis and the area under receiver operator characteristic curve(ROC)were used to explore the correlation between serum thyroid hormone levels and diagnostic data level of pre-sarcopenia.Results:Of 54 pre-sarcopenia patients, 30.3%(36/119)were male, 18.0%(18/100)were female with statistically significantly differences( P<0.01). Mean age was higher in both male and female patients in the NTIS group than in the non-NTIS group( P<0.01). The body mass index, levels of triiodothyronine(T3), free triiodothyronine(FT3), hemoglobin, and albumin were lower in NTIS group than in non-NTIS group( P<0.05). The prevalence of presarcopenia in female patients was higher in the NTIS group than in the non-NTIS group[42.9%(10/17) vs.10.6%(8/83), χ2=9.564, P<0.01]. Multivariate logistic regression analysis showed that the risk of pre-morbidity of sarcopenia was significantly higher in NTIS patients than in non-NTIS patients.FT3 was positively correlated with skeletal muscle mass index, fat-free body weight, and phase angle, and negatively correlated with visceral fat area( r=-0.17, P<0.05). While, free thyroxine(FT4)was negatively correlated with skeletal muscle mass index( r=-0.21), fat-free body weight( r=-0.16)and phase Angle( r=-0.2, P<0.01 or P<0.05), and was positively correlated with body fat percentage and visceral fat area( r=0.20 and 0.22, respectively, P<0.01). The use of area under ROC curve(AUC)of FT3 predicting sarcopenia stage showed that the AUC was 0.768(95% CI: 0.691~0.844). Conclusions:In elderly patients, NTIS is correlated with the pre-sarcopenia in the elderly, and FT3 and FT4 are related to muscle mass.The low level of FT3 can predict the pre-validation of pre-sarcopenia.

Objective:To explore the relationship between AluYb8 insertion in the MUTYH gene and the risk of decreased left ventricular diastolic function in the elderly.Methods:In the retrospective analysis, 498 elderly patients with decreased left ventricular diastolic function(the disease group)and 155 people without left ventricular diastolic function(the control group)were recruited.Polymerase chain reaction was employed to analyze the genotype distribution of AluYb8 insertion in MUTYH gene.Cardiac function was measured by high-resolution color Doppler ultrasound.Results:The frequencies of the A/A, A/P and P/P genotypes were 30.1%(150/498), 48.4%(241/498)and 21.5%(107/498)in patients with decreased left ventricular diastolic function, and 27.7%(43/155), 54.8%(85/155)and 17.5%(27/155)in the control group, respectively.There were no significant differences in genotype( χ2=2.162, P=0.339)and allele frequency( χ2=1.342, P=0.794)between the two groups.Further analysis after stratification revealed that there were statistically significant differences in genotype( χ2=7.173, P=0.028)and allele frequency( χ2=8.352, P=0.015). Multivariate Logistic regression analysis showed that, in elderly patients with diabetes, P-allele carriers had a higher risk of decreased left ventricular diastolic function than non-carriers( OR=3.450, 95% CI: 1.148-10.372, P=0.027). Conclusions:AluYb8 insertion in the MUTYH gene may be associated with the risk of decreased left ventricular diastolic function in the elderly with diabetes.

Objective To Investigate the immune status and influencing factors of provincial polio network laboratory (PNL) workers in China so as to provide evidence for the development of related strategies to protect personnel working at the PNLs.Methods All the practitioners from the PNLs at the provincial centers for disease control,were selected as objects for this study,from October to December,2016,under a questionnaire survey.Information on status of immunity and influencing factors was collected,with SAS software,trend chi-square used for statistics analysis.Results A total of 77 workers were involved in this survey,with 60 (78％) of them completed the polio-based immune program but the rest 17 (22％) remained records unclear.66 people (about 86％) remembered clearly that they had received vaccination when engaging in the polio-lab work,but the rest 11 (14％) with only partial vaccination records.We also noticed that the Influencing factors realted to vaccination status were:age (x2 =2.48,P＜0.05),title (x2 =2.51,P＜0.05),years of employment (P＜0.000 1),education (x2 =0.74,P=0.46) and gender (x2 =0.46,P=0.50).Conclusion Immune status of the Chinese provincial PNL practitioners appeared fairly good as 86％ of all the workers had received polio-related vaccination,with 41％ of them completed a 3-time inoculation program,when started working in this field.

Objective To investigate the relationship between systemic immune-inflammation index (SII)and lower extremity vascular disease in patients with type 2 diabetes mellitus (T2DM).Methods A cross-sectional study was conducted on 390 T2DM patients admitted in our department from January 2013 to January 2024.According to the diagnostic criteria for lower extremity vascular disease in T2DM patients,they were divided into a lower extremity vascular disease group (n=158)and a control group (n=232).General data and results of laboratory tests were compared between the 2 groups.Spearman correlation analysis was used to identify the related factors for lower extremity vascular diseases in T2DM patients.The correlation between SII and lower extremity vascular diseases in T2DM patients was analyzed using the Row Mean Scores and Cochran-Armitage Trend analysis.Multivariate logistic regression analysis was applied to identify the risk factors for lower limb vascular lesions in T2DM patients.Receiver operating characteristic (ROC)curve was plotted to evaluate the diagnostic efficacy of SII for lower extremity vascular disease in the patients.Results Compared with T2DMpatients without lower extremity vascular disease,those with lower extremity vascular disease were older,had higher levels of total cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),SII,larger proportion of carotid vascular lesions,and increased proportion of no-taking statins.The lower extremity vascular disease in T2DM patients was positively correlated with SII/100 (r=0.429,P<0.001),age (r=0.517,P<0.001),TC (r=0.161,P=0.001),LDL-C (r=0.117,P=0.021),carotid artery lesions (r=0.101,P=0.047),no-taking statins (r=0.266,P<0.001).Logistic regression analysis showed that SII,age,LDL-C,and no-taking statins were the risk factors for lower extremity vascular lesions in T2DM patients (P<0.01).The area under the curve (AUC)value of SII combined with age,LDL-C,and no-taking statins in predicting lower extremity vascular disease in T2DM patients was 0.896.Conclusion SII is not only a risk factor,but also a simple marker for lower extremity vascular disease in T2DM patients,suggesting that inflammatory response plays an important role in the occurrence and development of lower extremity vascular disease in T2DM.

Objective To systematically evaluate the risk prediction models for anastomotic leakage (AL) in patients with esophageal cancer after surgery. Methods A computer-based search of PubMed, EMbase, Web of Science, Cochrane Library, Chinese Medical Journal Full-text Database, VIP, Wanfang, SinoMed and CNKI was conducted to collect studies on postoperative AL risk prediction model for esophageal cancer from their inception to October 1st, 2023. PROBAST tool was employed to evaluate the bias risk and applicability of the model, and Stata 15 software was utilized for meta-analysis. Results A total of 19 literatures were included covering 25 AL risk prediction models and 7373 patients. The area under the receiver operating characteristic curve (AUC) was 0.670-0.960. Among them, 23 prediction models had a good prediction performance (AUC>0.7); 13 models were tested for calibration of the model; 1 model was externally validated, and 10 models were internally validated. Meta-analysis showed that hypoproteinemia (OR=9.362), postoperative pulmonary complications (OR=7.427), poor incision healing (OR=5.330), anastomosis type (OR=2.965), preoperative history of thoracoabdominal surgery (OR=3.181), preoperative diabetes mellitus (OR=2.445), preoperative cardiovascular disease (OR=3.260), preoperative neoadjuvant therapy (OR=2.977), preoperative respiratory disease (OR=4.744), surgery method (OR=4.312), American Society of Anesthesiologists score (OR=2.424) were predictors for AL after esophageal cancer surgery. Conclusion At present, the prediction model of AL risk in patients with esophageal cancer after surgery is in the development stage, and the overall research quality needs to be improved.
