Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To investigate the effect of different timing of arterial -venous extracorporeal membrane oxygenation (VA-ECMO) on the prognosis of patients with acute myocardial infarction complicated with cardiogenic shock (AMICS).Methods:This study was a prospective cohort study. AMICS patients received VA-ECMO support primary percutaneous coronary intervention in Henan Provincial People's Hospital from May 2017 to July 2023 were divided into early VA-ECMO group and late VA-ECMO group. 64 AMICS patients who met the indications for VA-ECMO implantation, but did not revive VA-ECMO were included as control group. Demographic characteristics, coronary interventional (PCI) information and complications after VA-ECMO implantation were collected. The primary end points was 1-year survival, minor end point were in-hospital and perioperative death. Multivariate Logistic and Cox regression models were used to evaluate the effect of timing of VA-ECMO on prognosis of AMICS patients. Kaplan-Meier survival curve was used to analyze the 1-year survival outcome of the 3 groups.Results:A total of 143 AMICS patients were included, and materials of 136 patients entered in the final analysis, including 42 in the early VA-ECMO group, 34 in the late VA-ECMO group, and 60 in the non-VA-ECMO group. Compared with the late VA-ECMO group, the early VA-ECMO group had a higher ratio of PPCI after VA-ECMO, a longer D-to-B time, a shorter VA-ECMO support time, a higher success rate of VA-ECMO withdrawal, and a lower complication rate (all P<0.05). Compared with the early VA-ECMO group, the perioperative, in-hospital and 1-year mortality were significantly higher in Non-ECMO support (all P<0.05). There was no difference in perioperative and in-hospital mortality between the early VA-ECMO group and the late VA-ECMO group, but the 1-year mortality in the late VA-ECMO group was significantly higher ( P<0.05). Perioperative, in-hospital and 1-year mortality rates were lower in the late VA-ECMO group than in the no-VA-ECMO group, but the differences were not statistically significant. Multivariate Logistic and Cox regression analysis showed that after adjusting interference factors, early VA-ECMO was still a protective factor for in-hospital ( OR=0.244, P=0.015) and one year ( HR=0.308, P=0.001)mortality. Kaplan-Merier survival curve showed that compared with the late VA-ECMO group and the group without VA-ECMO, the early VA-ECMO group had the highest 1-year survival rate. Conclusion:Patients with AMICS may benefit more from early VA-ECMO than from late VA-ECMO support for PPCI.

Objective: To evaluate the effectiveness of the SHARP intervention model for increasing students’ moderate to vigorous physical activity (MVPA) levels,and to provide a reference for physical activity enriching intervention among middle schools students’. Methods: One-year interventional teaching was carried out in 6 schools selected in the terms of scale and demographics from Nanjing City, Jiangsu Province. Data were collected during physical education (intervention group 105, control group 113; pre-intervention 119, post-intervention 99) data for 218 students. MVPA was assessed at baseline and post-intervention using the Observed Health and Coaching Time System(SOFIT). Interviews with 19 teachers were conducted with intervention schools to explore teachers’ views on interventions. Results: The two-way analysis of variance showed that the intervention of the SHARP model had a significant impact on MVPA, VPA, and motor skills of middle school students. Proportion of the average MVPA class time of the intervention school students(62.80±9.11), and the average proportion of the VPA class time of the intervention school(24.33±12.55), the average class time for intervention in the school’s mastery of skills(32.34±11.78)(t=-7.46, -4.82, -12.08, P<0.01). The MVPA of students in control school remained relatively constant while the VPA decreased. Classroom teaching capability improved significantly in intervention schools, which was further confirmed by teacher interviews. Conclusion The SHARP intervention model can effectively increase the MVPA level of middle school students.

Objective:To investigate the risk factors of ST-segment elevation myocardial infarction (STEMI) with early left ventricular thrombus (LVT) under emergency percutaneous coronary intervention(PCI)mode.Methods:The clinical data were collected from 784 patients with STEMI treated with emergency percutaneous coronary intervention (pPCI) in our hospital from January 2014 to April 2019 . The observation indexes included baseline data, coronary angiography, disease course, laboratory examination and auxiliary examination. Patients with severe organic heart disease and having previous history of LVA and LVT were excluded. Totally 38 patients with LVT were selected as the experimental group and 114 patients with non-LVT selected as the control group according to the principle of age (the smallest absolute age difference between the experimental group and the control group) and sex. Data was analyzed by software Graphpad Prism5, SPSS 22.0 and Medcalc software were used for statistical analysis, and the Logistic regression model was established. A P<0.05 was considered statistically significant, and the risk factors of early LVT formation were retrospectively analyzed. Results:There was a linear relationship between the prolongation of TIT and the occurrence of LVT ( χ2= 304, P<0.01), and the Spearman relation was highly positive ( ρ=0.626, P<0.01). Multivariate conditional logistic regression analysis showed that prolonged TIT (total ischemic time), increased total amplitude of ST elevation, TIMI blood flow ≤ grade 2 after pPCI, decreased LVEF and LVA were independent risk factors for LVT, and their odds ratios ( OR) were 1.996, 13.689, 16.996, 0.868 and 9.195, respectively. Model 1 was constructed as LVA and the total amplitude of elevation of ST segments, and the receiver operating characteristic (ROC) was drawn, and the area under the ROC curve (AUC) was calculated as 0.889. Model 2 was obtained by adding TIT, LVEF and postoperative TIMI blood flow≤2, and the AUC was 0.990. Delong method was used to compare the AUC values between the two groups, and there was a statistical difference ( Z=3.294, P=0.001). Conclusions:The risk factors of STEMI complicated with early LVT under "emergency PCI mode" may have changed. Clinicians should conduct early screening of high-risk people factors of LVT in order to reduce its incidence and improve the prognosis. It may be helpful to actively carry out emergency bedside echocardiography before operation.

Objective:To investigate the characteristics of coronary angiography and types of intracoronary thrombus in patients with acute myocardial infarction (AMI) who were classified according to changes of ST segment in electrocardiogram (ECG).Methods:A total of 232 consecutive AMI patients within 24 h of symptom onset undergoing primary percutaneous coronary intervention (PCI) in Henan Provincial People’s Hospital from September 2016 to August 2018 were included. According to the changes of ST segment, patients were divided into three groups: ST-elevated group (161 cases), ST-unoffset group (28 cases) and ST-depression group (43 cases). Optical coherence tomography (OCT) during primary PCI were performed and intracoronary thrombus types were differentiated according to OCT. One-way analysis of variance, Chi-square test and Fisher exact probability test were used to analyze the clinical baselines, angiographic characteristics and intracoronary thrombus types among the three groups. A P<0.05 was considered statistically significant. Results:Left anterior descending coronary artery and right coronary artery were the most common infarct related arteries in the ST-elevated group and ST-depression group, while left circumflex artery was more common in the ST-unoffset group ( P<0.001). The infarct sites in the ST-elevated group and ST-depression group were mostly located in the proximal and middLe segments, while those in the ST-unoffset group were mostly located in the middLe and distal segments ( P=0.008). The proportion of occlusive lesion in the ST-elevated group and ST-unoffset group was higher than that in the ST-depression group (68.3% vs. 30.2%, P<0.05; 67.9% vs. 30.2%, P<0.05). The proportion of single vessel in the ST-elevated group and ST-unoffset group was higher than that in the ST-depression group (36.0% vs. 4.7%, P<0.05; 39.3% vs. 4.7%, P<0.05). The proportion of collateral circulation of infarct related artery in the ST-unoffset group and ST-depression group was higher than that in the ST-elevated group (35.7% vs. 16.1%, P<0.05; 58.1% vs. 16.1%, P<0.05). The incidence of red thrombus in the ST-elevated group and ST-unoffset group was significantly higher than that in ST-depression group (76.4% vs. 34.9%, P<0.05; 64.3% vs. 34.9%, P<0.05). Conclusions:Compared with the ST-depression group, the proportions of single-vessel, occlusive lesion and red thrombus are higher in the ST-unoffset group and ST-elevated group. Therefore, in acute non ST-segment elevated myocardial infarction, those without ST-segment deviation are different from those with ST-segment depression. It is recommended to further divide acute myocardial infarction into ST segment elevation type, ST segment unoffset type and ST segment depression type according to ECG.

Objective To investigate the delay of door to signature time in primary percutaneous coronary intervention (PCI) and its influence in patients with ST segment elevation myocardial infarction (STEMI),therefore to provide a scientific basis for further effective shortening the time of primary PCI in patients with STEMI.Methods A total of 226 patients who diagnosed with STEMI and underwent primary PCI at Henan Provincial People's Hospital from June 2016 to December 2017 were enrolled in the study.Observation indicators include:(1) baseline data of patients;(2) time segments in primary PCI:total ischemic time (TIT),door to balloon time (DTBT),door-to-signature time (DTST),signature to balloon time (STBT);(3) the demographic characteristics of the family members who signed informed consent;and (4) the psychological factors and coping strategies of family members before signing informed consent.All data was analyzed using SPSS software (version 22.0).Multiple linear regression analysis was used to analyze the influencing factors of delay of DTST.A P＜0.05 was considered statistically significant.Results In this study,226 patients with STEMI who were first diagnosed in our hospital had a mean age of 55.23±10.80 years,and 181 (80.1％) were male.The median of TIT,DTBT,DTST,STBT were 312 min,166 min,82 min,and 80 min.The ratio of DTST in DTBT and TIT was 50％ and 28.5％,respectively.The multiple linear regression analysis showed that the number of direct family members (P＜0.001),the degree of educational in middle school and below (P=0.010),high school/technical secondary school (P=0.029),families worrying about the high cost of medical care (P=0.020),families consulted each other repeatedly (P=0.022),and consulted the other medical staff(P=0.022) are risk factors of DTST delay,and city residence (P=0.048) is the protection factor of DTST delay.Conclusions The long time of DTS is a reality of the practice of primary PCI in China.The factors that lead to longer DTST include demographic characteristics,psychological factors and coping strategies of family members.The STBT of primary PCI in China should be taken into the value while emphasizing the DTBT.

Objective To explore the related factors affecting the formation of different types of thrombosis in patients with STEMI. Methods Retrospective data were collected from September 2014 to October 2018 in Henan Province People's Hospital for emergency interventional treatment of patients with STEMI. According to the type of thrombus detected by OCT, they were divided into two groups, which were red thrombus group and white thrombus group. Clinical baseline data, coronary angiographic findings, and OCT results were collected in patients with STEMI. Logistic regression analysis was used to analyze the type of thrombosis in patients with STEMI. Results The rate of thrombus detection was 100％ in 92 patients with STEMI. According to OCT diagnostic criteria, 73 (79.3％) patients were classified into red thrombus and 19 (20.7％) were white thrombus. There was no significant difference in infarct-related artery and location between the two groups (P>0.05) , but there was more multiple vascular lesions in the white thrombus group than that in the red thrombus group. There was significant difference in the incidence of plaque rupture and thin fibrous cap in the two groups (P<0.05). The incidence of plaque rupture and thin fibrous cap lipid plaque was higher in the red thrombus group. Plaque rupture (OR = 2.894, 95％CI:2.704-2.956) , thin fibrous cap plaque (OR = 8.033, 95％CI: 7.985-8.283) , single vessel disease (OR = 1.746, 95％ CI: 1.659-1.785) are risk factors for red thrombosis formation. Conclusion Single vessel lesion, plaque rupture andthin fibrous cap lipid plaque are associated with red thrombus formation.While, multiple vessel lesions and stable plaque are associated with white thrombus formation.

Objective To observe the clinical efficacy of umbilical compress with anti-cancer Xiaogu formula in managing malignant ascites. Methods A total of 56 patients with malignant ascites who met the inclusion criteria were randomized into 28 patients in the treatment group and 28 patients in the control group. The control group was treated with one type of diuretic, and the treatment group was given umbilical compress using Anti-Cancer Xiaogu formula and diuretics. Both groups were treated for 14 days. The changes of abdominal girth, 24 h urine volume, ascites efficacy, TCM syndrome scores, quality of life and adverse reactions were observed. Results The decrease in the maximum depth difference of the ascites in the treatment group was significantly greater than that of the control group (1.16 ± 1.29 vs. 0.00 ± 1.34, Z=-2.553). The difference was statistically significant (P<0.05). The decrease in abdominal girth in the treatment group was significantly larger than that in the control group (0.57 ± 0.55 vs. 2.61 ± 0.28, Z=-2.264). The difference was statistically significant (P<0.05). The in 24-hour urine volume in the treatment group after intervention (-800.18 ± 64.12 vs.-683.57 ± 55.38, Z=-1.770) was no statistically significant (P>0.05). The response rate in the treatment group was 92.9％ (26/28), while that of the control group was 89.3％ (25/28).treatment group was 71.4％, while that of the control group was 35.7％. The difference was statistically significant (P<0.05). The increase in KPS in the treatment group was significantly higher than that of the control group. The difference was statistically significant (P<0.05). Conclusions Anti-cancer Xiaogu umbilical cord combined with diuretic can reduce the degree of malignant ascites, alleviate clinical symptoms, improve quality of life and decrease the occurrence of adverse reactions when used concomitantly with diuretics in the management of malignant ascites.

Objective To study the time extended for getting emergency intervention in different modes of transportation and factors influencing the modes of transportation of patients with ST elevation myocardial infarction (STEMI).Methods A total of 564 consecutive patients with STEMI admitted from September 2013 to June 2016 were enrolled in the study.The clinical data about time consumed for getting emergency intervention and modes of transportation were collected.Results According to the mode of transportation,patients were divided into three groups:emergency care system (EMS) transportation group (n =96),self-transportation group (n =206) and referral group in which the patients were sent in from other hospitals (n =262).EMS transportation group had significantly shorter total ischemic time before emergency treatment than self-transportation group (229 rin vs.418 min,P ＜ 0.05) and referral group (229 min vs.512 rin,P ＜ 0.05),and significantly shorter length of pre-hospital time than self-arrival group (55 min vs.110 min;P＜0.05) and referral group (55 min vs.372 min;P＜0,05).The referral group had longer pre-hospital time and the self-transportation group had longer door-to-balloon time,but there was no difference in total ischemic time between the self-arrival and referral group (Z =-1.882,P =0.068).Multivariate logistic regression was used to analyze influence factors in mode of transportation:(1) patients characterized with high school or university education,profession of civil service,and their transportation distance more than 30 km were greater in number than referral group (P ＜ 0.05);(2) patients identified with senior middle school education,staff member of public sectors or company,their transportation distance less than 30 km,and with killip grade above Ⅱ were more likely to have EMS transport (P ＜ 0.05);(3) patients defined as businessmen without taking out new rural cooperative medical insurance,taking up transportation distance less than 80 km,and subjecting to killip grade Ⅰ had a higher proportion of individuals of this kind taking self-transportation (P ＜ 0.05).Conclusion Mode of transportation is an important factor that affects the time extended to get emergency intervention.Education level,occupation,medical insurance type,transportation distance,killip grade are associated with modes of transport.

Objective To investigate the clinical characteristics and the associated risk factors for short-term prognosis in elderly patients with acute decompensated heart failure, in order to provide the evidence for improving clinical survival.Methods Clinical data of 200 elderly patients with acute decompensated heart failure in our hospital from June 2010 to December 2014 were retrospectively analyzed.The associated risk factors for prognosis were analyzed by using multivariate logistic regression analysis.All patients were followed up for six months, and cardiovascular events during the same follow-up period were recorded.All patients were divided into non-event group (n=158, no readmission during the follow-up period) and event group (n=42, readmission or death during follow-up).Results All the 200 elderly patients with acute decompensated heart failure had completed the 6 months follow-up, 23 (11.5％) patients died from cardiovascular events, and 19 (9.5％) patients had readmission due to heart failure.New York Heart Association (NYHA) classification, age, heart rate, systolic blood pressure, left ventricular ejection fraction (LVEF), left ventricular end-systolic diameter (LVESD), and left ventricular end-diastolic dimension (LVEDD) had significant differences between the two groups (x2=5.791, t=2.514, 2.552, 2.500, 2.582, 3.870, 2.275, all P＜0.05).Levels of NT-terminal pro-brain natriuretic peptide (NT-proBNP), high sensitivity C reactive protein (hs-CRP), red cell distribution width (RDW), creatinine, and uric acid were higher in the event group than in the non-event group (t=54.948, 9.932, 2.815, 8.888, 2.368, all P＜0.05).The hemoglobin level was lower in the event group than in the non-event group (t-2.455, P＜0.05).Multivariate unconditional logistic regression analysis showed that NYHA classification, LVEF, and NT-proBNP were the independent risk factors for the prognosis of acute decompensated heart failure in elderly patients (x2 =10.438, 61.943, 6.976, all P＜0.05).The mortality rate was 11.5％ within the six months follow-up.The area under the receiver operating characteristic (ROC) curve for NT-proBNP to predict short-term mortality was 0.860 (SE=0.034,P=0.000, 95％ CI: 0.794-0.926).The mortality within 6 months was lower in NT-proBNP ≤205 ng/L group than in NT proBNP＞ 205 ng / L group (x2=5.385, P=0.020).Conclusions NYHA classification, LVEF, and NT proBNP are the risk factors for the prognosis of acutely decompensated heart failure in the elderly.The elderly patients with acute decompensated heart failure have a poor prognosis.
