Objective To compare blood pressure control in community hypertensive patients with different management methods.Methods Two neighborhood committees in a community of Pudong were selected as study area using cluster sampling method.A total of 5 166 residents aged ≥35 y were screened for blood pressure; the subjects with high blood pressure and had antihypertensive medication in last 6 months were included,and patients with secondary hypertension was excluded.The patients who entered community hypertension management program and got medication from community were included in community group; those who did not enter in community management program and/or not get medication from community were included in non-community group.Self-designed questionnaire was used for investigation.The medication compliance,awareness of hypertension risk factors and high blood pressure control were compared between two groups.Results Among 5 166 residents 4 763 were surveyed for hypertension with a response rate of 92.2％ and hypertension prevalence rate of 23.2％ (1 105/4 763).Among 1 012 patients with drug treatment for more than 6 months,there were 878 cases in community (86.8％) and 134 cases (13.2％) in non-community group.There were no significant differences in gender,age,education,working condition between community group and non-community group (P ＞ 0.05).44.3％ (389/878) patients in community group had a history of high blood pressure ＞ 10 y and that was 56.7％ (76/134) in non-community group (P =0.011) ; 28.6％ (251/878) patients in community group were at high risk for risk stratification and that in non-community group was 47.8％ (64/134) (P ＜0.001).The awareness of hypertension risk factors in community group and non-community group was 83.9％ and 95.5％,respectively (P ＜ 0.001).The medication compliance and blood pressure control rates in two groups were 93.2 ％ and 84.3 ％ (P ＜ 0.001),68.6％ and 51.5 ％,respectively (P ＜ 0.001).Conclusion The outcomes of hypertension management in terms of medication compliance and blood pressure control in community group are better than those in non-community group.

Objective: To evaluate the post-operative complication of pulmonary vein stenosis in patients with total anomalous pulmonary venous connection (TAPVC) by echocardiography.
Methods: A total of 66 TAPVC pediatric patients with surgical repair in our hospital were retrospectively studied. The peri-operative and mid-term post-operative echocardiography was conducted to evaluate the complication of pulmonary vein stenosis.
Results: The peri-operative and mid-term post-operative echocardiography presented the increased left ventricular diastolic end diameter (LVEDd) and decreased right ventricular diameter in all 66 patients, P<0.05. There were 6 patients with pulmonary vein stenosis showed high velocity Doppler signals at atanastomosis. The peri-operative echocardiography in those 6 patients showed increased LVEDd, decreased right ventricular diameter and pulmonary artery pressure, all P<0.05. The mid-term post-operative echocardiography in those 6 patients indicated increased LVEDd, P<0.05, while the right ventricular diameter and pulmonary artery pressure were similar before and after the operation, P>0.05.
Conclusion: Echocardiography may monitor the operative effect of TAPVC, the occurrence of post-operative pulmonary vein stenosis could be found by examining right ventricular diameter and pulmonary artery pressure in pediatric patients.

Objective To evaluate the role of echocardiography in diagnosis and post-operative evaluation of infants and children with double aortic arch. Methods Echocardiography was performed in 6 patients with double aortic arch from January 2006 to June 2008. The outcome of postoperative follow-up was also evaluated. Results Six patients ranged in age from 3 months to 4 years and averaged 18 months. There were 2 boys and 4 girls. Echocardiography diagnosed double aortic arch in 4 patients, one balanced arch and 3 right arch dominant, and was confirmed by surgical observation in each patient. The size of the two arches were almost same in balanced arch,and the diameter of right arch was bigger than that of left arch in right arch dominant. Echocardiography failed to diagnose in 2 patients with balanced arch. Three patients had associated heart defect, such as patent ductus arteriosus and ventricular septal defect. Five of the 6 patients underwent surgical division of the left arch in order to relieve esophageal and tracheal compression. At about 2 years postoperative follow-up,echocardiography can clearly show the flow of aortic arch and it's branches. Conclusions It is an important clue to double aortic arch if only two branches of aortic arch was shown on supersternal view by echocardiography. As a non-invasive techniqe, echocardiography is useful for diagnosing and post-operative evaluating of patients with double aortic arch.

Among the staff of Beijing Chao-Yang Hospital, Capital Medical University, who received the inactivated SARS-CoV-2 vaccine on January 30 in 2021, 28 recipients were selected for this research. Samples for nucleic acid tests were collected from the surface of the recipients′ both hands before and after vaccination. The hemostatic stickers used after the inoculation were also collected for nucleic acid tests. The nucleic acid tests of the samples collected from the surface of both hands of the 28 recipients before vaccination were all negative. After vaccination, the nucleic acid tests of the samples collected from the surface of both hands of recipients were positive in 3 cases, and suspicious in 8 cases, with a positive rate of 10.7%. A total of 25 hemostatic stickers used were collected, 24 of them had positive nucleic acid tests, and the rest one had suspicious nucleic acid test result, with a positive rate of 96%. The hemostatic stickers used after the inoculation have the risk of nucleic acid contamination.

Objective? To explore the clinical effects of evidence-based psychological intervention on nursing care for middle-aged patients with ischemic stroke. Methods? Totally 120 patients aged 45-59 years who were hospitalized in the Department of Neurology, Cangzhou People's Hospital between February and July were selected, and stratified into intervention (n=60) and control (n=60) groups. Patients in the control group received conventional nursing care, while patients in the intervention group received psychological intervention based on conventional nursing care. Self-Depression Scale (SDS) was used to assess the status of patients in the two groups. Results? After 4 weeks, the SDS score of the intervention group was (52.37±4.38), whereas the SDS score of the control group was (58.81±3.44). The SDS score was lower in the intervention group than in the control group, and there was statistically significant difference between the two groups (P＜ 0.01). Conclusions? The evidence-based psychological intervention model helps to ameliorate the depression in middle-aged patients with ischemic stroke, which is worthy applying and promoting in clinical practice.

Objective To summarize the echocardiographic findings and clinical characteristics of Kawasaki disease(KD) complicated with coronary artery thrombosis (CAT).Methods Thirty-five patients with KD combined with CAT were enrolled,who were admitted to Beijing Children's Hospital,Capital Medical University between July 2005 and August 2016.The clinical characteristics and echocardiographic findings during follow-ups were retrospectively studied.According to whether the childrenhad been complicated with myocardial ischemia,the patients were divided into 2 groups:ischemic group and non-ischemic group.The duration of fever,the time when the intravenous immunoglobulin(IVIG) was first injected,the time when coronary artery aneurysms (CAA) was formed,the maximum diameter of CAA and inflammatory index inthe acute phase were compared between 2 groups.Results All of the 35 children diagnosed as KD combined with CAT suffered firom CAA,and the coronary thrombosis was detected in all the cases with aneurysms.Thirty-five patients had 99 branches of CAA,of which the maximum diameter of CAA was (9.6 ± 3.1) mm(4.0-19.0 mm).Fifty-four plots of CAT were detected in the aneurysms.The diameter of CAA that thrombosis located was larger than that of which the thrombosis was not located[(10.9 ± 2.8) mm vs.(7.9 ± 2.6) mm],and the difference was significant(P ＜0.01).During 4 months to 10 years and 8 months [(39.2 ±29.5) months] follow-ups,CAA regressed in 32 branches [32.3％ (32/99 branches)],of which 4 branches [4.0％ (4/99 branches)] completely regressed to the normal diameter.The maximum diameter of CAA regressed was smaller than the maximum diameter of CAA consistence [(7.3 ± 1.9) mm vs.(10.6 ± 3.0) mm],and the difference was significant (P ＜ 0.01).Out of 35 patients,15 cases [42.9％ (15/35 cases) had myocardial ischemia,while the other 20 cases[57.2％ (20/35 cases)] didn't have.Among 15 cases with myocardial ischemia,6 cases[17.1％ (6/35 cases)] had myocardial infarction,4 cases [11.4％ (4/35 cases)] had heart failure,and 1 case[2.9％ (1/35 cases)] died of acute heart failure complicated with severe ventricular arrhythmia.Compared with non-ischemic group,the children in the ischemic group had longer duration of fever[(19.1 ± 7.8) d vs.(12.1 ± 3.3) d],higher white blood cell account in the acute phase[(24.8 ± 13.5) × 1012/L vs.(19.7 ±4.0) × 1012/L],later treatment of IVIG [(13.9 ± 5.5) d vs.(9.8 ±3.8) d],and earlier CAA formation [(16.0 ±4.9) d vs.(20.9 ± 14.5) d],and the differences were statistically significant (all P ＜ 0.05).Conclusions CAT of children with KD commonly originates from CAA.Patients who have more serious inflammatory reaction in the acute phase,earlier formation,heavy severity and longer consistence of CAA are prone to have myocardial ischemia.Echocardiographic study plays an important role in monitoring CAA,detecting the CAT and finding the early left ventricle dysfunction,which is of clinical significance.

Objective:To study the risk factors of adverse pregnancy outcomes for induced abortion of cesarean scar pregnancy in midtrimester.Methods:A national multicenter retrospective study was conducted. A total of 154 singletons pregnant women with cesarean scar pregnancy during the second trimester induced abortion by various reasons in 12 tertiary A hospitals were selected, their pregnant outcomes were observed and the risk factors of serious adverse outcomes were analyzed with univariate and multivariate logstic regression; the role of ultrasound and MRI in predicting placenta accreta and severe adverse outcomes was evaluated, the effectiveness of uterine artery embolization (UAE) in preventing hemorrhage in pregnant women with and without placenta accreta was compared.Results:Among 154 subjects, the rate of placenta accreta was 42.2% (65/154), the rate of postpartum hemorrhage≥1 000 ml was 39.0% (60/154), the rate of hysterectomy was 14.9% (23/154), the rate of uterine rupture was 0.6% (1/154). The risk factor of postpartum hemorrhage≥1 000 ml and hysterectomy was placenta accreta ( P<0.01). For each increase in the number of parity, the risk of placenta accreta increased 2.385 times (95% CI: 1.046-5.439; P=0.039); and the risk of placenta accreta decreased with increasing ultrasound measurement of scar myometrium thickness ( OR=0.033, 95% CI: 0.001-0.762; P=0.033). The amount of postpartum hemorrhage and hysterectomy rate in the group with placenta accreta diagnosed by ultrasound combined with MRI were not significantly different from those in the group with placenta accreta diagnosed by ultrasound only or MRI only (all P>0.05). For pregnant women with placenta accreta, there were no significant difference in the amount of bleeding and hysterectomy rate between the UAE group [median: 1 300 ml; 34% (16/47)] and the non-embolization group (all P>0.05); in pregnant women without placenta accreta, the amount of bleeding in the UAE group was lower than that in the non-embolization group (median: 100 vs 600 ml; P<0.01), but there was no significant difference in hysterectomy rate [2% (1/56) vs 9% (3/33); P>0.05]. Conclusions:(1) Placenta accreta is the only risk factor of postpartum hemorrhage≥1 000 ml with hysterectomy for induced abortion of cesarean scar pregnancy in midtrimester; multi-parity and ultrasound measurement of scar myometrium thickness are risk factors for placenta accreta. (2) The technique of using ultrasound and MRI in predicting placenta accreta of cesarean scar pregnancy needs to be improved. (3) It is necessary to discuss of UAE in preventing postpartum hemorrhage for induced abortion of cesarean scar pregnancy in midtrimester.

Objective:To study the risk factors of adverse pregnancy outcomes for the diagnosis and treatment of pregnancy after cesarean section complicated with placenta previa.Methods:A national multicenter retrospective study was conducted to select a total of 747 pregnant women with the third trimester singleton pregnancy after cesarean section complicated with placenta previa from 12 tertiary hospitals in January 1st to December 31st, 2018. The risk factors of severe adverse outcomes [hysterectomy, intraoperative blood loss ≥1 000 ml, intraoperative diagnosis of placenta accreta spectrum disorders (PAS)] in pregnant women with second pregnancy complicated with placenta previa after cesarean section were investigated by logistic regression analysis. The roles of prenatal ultrasonography and magnetic resonance imaging (MRI) in the prediction of PAS and severe adverse outcomes were observed. According to whether vascular intervention was performed (uterine artery embolization or abdominal aortic balloon occlusion), the pregnant women were divided into the blocked group and the unblocked group, and the maternal and infant perinatal outcomes between the two groups were compared.Results:(1) General information: the hysterectomy rate of 747 pregnant women with second pregnancy complicated with placenta previa after cesarean section was 10.4% (78/747), the intraoperative blood loss ≥1 000 ml in 55.8% (417/747), and PAS was confirmed in 47.5% (355/747). The incidence of uterine rupture was 0.8% (6/747). (2) Analysis of risk factors for severe adverse outcomes: based on binary unconditioned logistic regression univariate and multivariate analysis, the risk factors for hysterectomy were the mode of vascular embolization and intraoperative blood loss. The probability of hysterectomy with uterine artery embolization was 5.319 times higher than that with abdominal aortic balloon occlusion (95% CI: 1.346-21.018). The risk factors of intraoperative blood loss ≥1 000 ml were the number of cesarean section delivery, ultrasonography indicated PAS and suspected PAS, intraoperative PAS and complete placenta previa. The risk factors for intraoperative PAS were uterine scar thickness, ultrasonography indicated PAS and suspected PAS, MRI indicated PAS and suspected PAS, and complete placenta previa. (3) The roles of ultrasonography and MRI in predicting PAS: the sensitivity and specificity of ultrasonography in predicting PAS were 47.5% and 88.4%; the kappa value was 0.279 ( P<0.001), with fair agreement. The sensitivity and specificity of MRI to predict PAS were 79.2% and 97.8%, respectively. The kappa value was 0.702 ( P<0.001), indicating a good agreement. The intraoperative blood loss and hysterectomy rate of pregnant women with PAS indicated by ultrasonography and MRI were significantly higher than those with PAS only by ultrasonography or MRI. (4) Influence of vascular occlusion on pregnancy outcome: there were no significant differences in intraoperative blood loss and incidence of intraoperative bleeding ≥1 000 ml between the blocked group and the unblocked group (all P>0.05). There was no significant difference in intraoperative blood loss between the pregnant women with abdominal aortic balloon occlusion, uterine artery embolization and those without occlusion ( P=0.409). The hysterectomy rate of pregnant women with uterine artery embolization was significantly higher than those with abdominal aortic balloon occlusion [39.3% (22/56) vs 10.0% (5/50), P=0.001]. Conclusions:In the third trimester of pregnancy with placenta previa after cesarean section, MRI examination has better consistency in predicting PAS than ultrasonography examination. Ultrasonography examination combined with MRI examination could effectively predict the hysterectomy rate and intraoperative blood loss. Vascular occlusion could not reduce the amount of intraoperative blood loss. The hysterectomy rate of pregnant women with uterine artery embolization is higher than those with abdominal aortic balloon occlusion.
