Objective:To evaluate the diagnostic performance of resting echocardiography in detecting severe coronary artery stenosis.Methods:A total of 136 patients with suspected coronary artery disease（CAD）who presented to Sichuan Provincial People's Hospital between January 2021 and December 2024 were prospectively enrolled. All patients underwent both coronary computed tomography angiography（CCTA）and transthoracic echocardiography within one week. Based on CCTA results，the patients were divided into non-severe stenosis group（ n=78）and severe stenosis group（ n=58）. Echocardiographic parameters including left atrial maximum volume（LAVmax），left ventricular global longitudinal strain（GLS），left ventricular longitudinal strain of endo-myocardium，mid-myocardium，epi-myocardium（LSendo，LSmid，LSepi），early diastolic mitral inflow velocity（E），early diastolic mitral annular velocity of the lateral and septal walls（e'），and E/e' were measured. Predictive factors for severe coronary stenosis were identified using LASSO regression，and a nomogram model was developed via multivariate Logistic regression. Model performance was evaluated using ROC curves，calibration curves，and decision curve analysis. Results:Multivariate Logistic regression analysis revealed LSendo，LAVmax，and E/e' as independent predictors of severe coronary artery stenosis. The nomogram constructed based on these predictors achieved an area under the curve of 0.798（95% CI=0.723-0.873），with sensitivity and specificity of 0.756 and 0.759，respectively. Conclusions:The resting echocardiography-based nomogram model demonstrates good diagnostic efficacy for severe coronary artery stenosis. It may serve as a noninvasive tool to assist in risk stratification and clinical decision-making in patients with suspected CAD.

Objective To explore the application value of popaverine combined with stage rehabilitation for patients after free flap grafting for hand trauma.Methods Data of postoperative patients who underwent hand trauma from January 2021 to January 2022 in The 903rd Hospital of the Joint Logistics Support Force of the People's Liberation Army of Chinawere retrospectively collected,and they were divided into the combined rehabilitation group(poppadine combined with stage rehabilitation care)and the stage rehabilitation group(only stage rehabilitation care was applied)according to the treatment methods.Visual analog scale(VAS)scores,rehabilitation exercise adherence scores,postoperative rates of excellent cutaneous sensory function of the hand,total active mobility(TAM)of the fingers,Jamar grip strength,upper extremity functional assessment(DASH)scale scores,and the incidence of vascular crises were compared between the two groups.Results A total of 120 cases were included in the study,with 57 cases in the combined rehabilitation group and 63 cases in the stage rehabilitation group.There was no statistically significant difference in VAS scores,Jamar grip strength and DASH scores between the two groups before surgery(P＞0.05);at 14 days and 3 months of intervention,VAS scores of the two groups decreased compared with the pre-intervention period(P＜0.05),and VAS scores of the patients in the combined rehabilitation group were significantly lower than those in the stage rehabilitation group(P＜0.05).After 3 months of intervention,the rehabilitation exercise adherence score,the rate of excellent hand skin sensory function,and finger TAM of the patients in the combined rehabilitation group were higher than those in the stage rehabilitation group(P＜0.05);Jamar grip strength were elevated in both groups compared with the pre-intervention period,but the combined rehabilitation group were higher than those in the stage rehabilitation group(P＜0.05);DSAH scores were lower in both groups compared to pre-intervention,and were lower in the combined rehabilitation group than in the stage rehabilitation group;and during the 3 months of intervention,the incidence of vascular crisis was significantly lower in patients in the combined rehabilitation group than in the stage rehabilitation group(P＜0.05).Conclusion Opium poppy alkaloids combined with stage rehabilitation can effectively reduce patients'postoperative pain,enhance patients'adherence to rehabilitation exercises,effectively improve postoperative hand function and upper limb motor function,and reduce the incidence of vascular crisis.

OBJECTIVE: To assess the practical and health economical values of non-invasive prenatal test (NIPT) in Changsha Municipal Public Welfare Program. METHODS: A retrospective analysis was carried out on 149 165 women undergoing NIPT test from April 9, 2018 to December 31, 2019. For pregnant women with high risks, invasive prenatal diagnosis and follow-up of pregnancy outcome were conducted. The cost-benefit of NIPT for Down syndrome was analyzed. RESULTS: NIPT was carried out for 149 165 pregnant women and succeeded in 148 749 cases (99.72%), for which outcome were available in 148 538 (99.86%). 90% of pregnant women from the region accepted the screening with NIPT. 415 (0.27%) were diagnosed as high risk. Among these, 381 (91.81%) accepted amniocentesis, which led to the diagnosis of 212 cases of trisomy 21 (PPV=85.14%), 41 cases with trisomy 18 (PPV=48.81%) and 10 cases with trisomy 13 (PPV=20.83%). The sensitivity and specificity of NIPT for trisomy 21, trisomy 18 and trisomy 13 were (97.70%, 99.98%), (97.62%, 9.97%) and (100%, 99.97%), respectively. In addition, 213 and 30 cases were diagnosed with sex chromosomal aneuploidies (PPV=46.2%) and other autosomal anomalies (PPV=16.57%), respectively. For Down syndrome screening, the cost and benefit of the project was 120.79 million yuan and 1,056.95 million yuan, respectively. The cost-benefit ratio was 1: 8.75, and safety index was 0.0035. CONCLUSION NIPT is a highly accurate screening test for trisomy 21, which was followed by trisomy 18 and sex chromosomal aneuploidies, while it was less accurate for other autosomal aneuploidies. The application of NIPT screening has a high health economical value.

ObjectiveTo investigate the prevalence rate and influencing factors of depression and anxiety in disabled people in Guang'an during the post-pandemic period， so as to provide references for promoting mental health of disabled people. MethodsFrom April to May 2021， the disabled people dwelling in low-risk areas for coronavirus infections in Guang'an for half a year and met the criteria outlined in Classification and Grading Criteria of Disability （GB/T26341-2010） were selected as the survey subjects， and their depression and anxiety symptoms were evaluated via the Patients' Health Questionnaire Depression Scale-9 item （PHQ-9） and the Generalized Anxiety Disorder Scale （GAD-7） through Wenjuanxing platform. Then binary Logistic regression analysis was performed to screen the risk and protective factors for depression and anxiety in disabled people. ResultsThe detection rates of moderate-to-severe and severe depressive symptoms were 9.05% and 8.35%， and the detection rates of moderate and severe anxiety symptoms were 9.40% and 11.25%. Regression analysis denoted that being laid-off and job-waiting were risk factors for depression and anxiety in disabled people （OR=2.354， 2.353， P<0.01）. Being unmarried （OR=0.418）， married （OR=0.414）， visual disability （OR=0.254）， limb disability （OR=0.460）， good family function （OR=0.241）， moderate family dysfunction （OR=0.288）， complete self-care （OR=0.062） and partial self-care （OR=0.416） were protective factors for depression in disabled people （P<0.05 or 0.01）. Visual disability（OR=0.382）， hearing disability（OR=0.143）， limb disability（OR=0.432）， good family function （OR=0.246）， moderate family dysfunction （OR=0.402）， complete self-care （OR=0.093） and partial self-care （OR=0.378） were protective factors for anxiety in disabled people （P<0.05 or 0.01）. ConclusionThe disabled people in Guang'an during the post-pandemic period suffer a high detection rate of depression and anxiety， and the detection rate is even higher among those being laid-off or job-waiting， while good family function and complete or partial self-care ability are conducive to protecting the mental health of the disabled.

Objective:To evaluate the effect of comprehensive intervention combined with clinical preventive services and lifestyle adjustment on high-risk populations of cardiovascular disease.Methods:In 2015, 4 towns (streets) in Tongxiang City, of Zhejiang Province including Heshan Town, Longxiang Street, Wutong Street, and Fengming Street, were selected by using the typical sampling. The towns (streets) were allocated to the intervention group (Heshan Town and Longxiang Street) and the control group (Wutong Street and Fengming Street) by using the cluster random sampling. In each town (street), hypertension patients aged 50 to 74 years old who were taking community medicine management and with a 10-year cardiovascular disease risk ≥10% were recruited as subjects. There were 1 823 subjects in the intervention group and 1 883 in the control group. The intervention group was given a 1-year comprehensive intervention combining clinical preventive services and lifestyle adjustment, while the control group received routine chronic disease management. After the intervention, the final questionnaire investigation was conducted and health physical examination data were obtained. The death, acute coronary heart disease events and stroke incidence were the primary outcomes, and cardiovascular disease-related knowledge and behavior, clinical preventive services utilization, physical changes, blood fat index and 10-year cardiovascular disease risk were the secondary outcomes. The difference-in-difference model was used to evaluate the effects of interventions.Results:The age of subjects in the intervention and control group was (68.76±3.75) and (67.90±4.56) years old, respectively. After 1-year intervention, the incidence of mortality, acute coronary events and stroke in intervention group was 1.65% (30 cases), 0.27% (5 cases) and 2.69% (49 cases), respectively, which showed no statistical difference compared to the control group [1.33% (25 cases), 0.32% (6 cases) and 2.07% (39 cases)]. After adjusting for the age, gender, education, marital status, self-assessed family income level and situation of taking antihypertensive drugs, the difference-in-difference model showed that the body mass index and diastolic blood pressure in the intervention group decreased by 0.33 kg/m 2 and 1.49 mmHg (1 mmHg=0.133 kPa). Compared with the control group, daily vegetable consumption proportion, the awareness rates of aspirin, stains, salt intake, and oil intake increased by 4.76%, 26.22%, 29.56%, 10.80%, and 15.17%, respectively ( P<0.05). Conclusion:After the 1-year comprehensive intervention, there was no significant change in primary outcomes among high-risk populations of cardiovascular disease. In secondary outcomes, body mass index and diastolic blood pressure declined and cardiovascular disease-related knowledge awareness increased.
