Objective To investigate the early diagnosis of sudden cardiac death so as to increase the resuscitating success rate.Methods 24 cases with sudden cardiac death were analyzed.Results In 24 cases,there were 10 cases resuscitated successfully,8 cases with heartbeats recovered died in 1～3 days,5 of which had average blood glucose of 21.6 mmol/L and blood sodium of 156 mmol/L,and 6 cases resuscitated unsuccessfully.Conclusion 70.83% was caused by AMI in 24 cases.The early diagnosis of AMI is mainly based on clinical manifestation.Althogh early ECG did not show it,AMI should not be denied and misdiagnosed.Resuscitation should be performed on the spot as soon as cardiac arrest occurs.Naloxone and NaHCO3 should be used rationally.Meanwhile,be sure to prevent and treat reperfusion-injury.The prognosis would be extremely poor if the patient showed hyperglycemia and hypernatremia during resuscitation.

Aim To explore the anti-proliferation and apoptotic effects of C085, a curcumin derivative, on K562 cells and its mechanism. Methods MTT assay and flow cytometry were used to examine cell prolifera-tion and apoptosis, respectively. The phosphorylation levels of Bcr-Abl initiated signaling proteins were ana-lyzed using Western blot. Results The results showed that C085 suppressed the growth of K562 cells and the IC50 value was about 5-fold lower than that of Cur. C085 also induced significant apoptosis on K562 cells in 24 hours when compared with imatinib. Western blot results demonstrated that C085 down-regulated the phosphorylation of Bcr-Abl in K562 cells in a dose-de-pendent manner. The phosphorylation of Stat 5 and
Crkl, which were downstream signaling proteins of Bcr-Abl kinase, was also inhibited by C085. C085 caused the opening of mitochondrial PT holes as detected by JC-1 fluorescent, which inhibited Bcl-2 and enhanced Bax , then induced apoptosis. Conclusion C085 in-hibited BCR-ABL+ K562 cells through inhibiting BCR-ABL kinase activity and down-regulating its down-stream signal proteins. Directly acting on mitochondrial PT hole and then activating apoptosis- associated pro-teins are also involved in the pro-apoptotic effect of C085 .

Objective To explore the relationship between syncope and risk of death in patients with cardiovascular emergencies including acute myocardial infarction(AMI), arrhythmia, acute heart failure(AHF), pulmonary thromboembolism(PTE) and aortic dissection(AD) rupture. Methods Data from 2 789 patients with cardiovascular emergency admitted from June 2010 to June 2016 in the Emergency Department, Air Force General Hospital, PLA was retrospectively analyzed. Difference in gender, age and motality were compared between patients with syncope and those without syncope. Among fi ve kinds of cardiovascular emergency events with syncope, difference in mortality were compared. Difference in mortality were also analyzed by the CHM corrected chi square test when difference of disease, gender and age were taken into consideration. Syncope, the type of cardiovascular emergency, gender and age were analyzed as potential risk/protective factors for death by the multiple logistic regression analysis. Results The mortalities of the fi ve diseases accompanied with syncope were 50%, 30.43%, 26.53%, 20% and 7.04% respectively in arterial dissection, pulmonary embolism, acute myocardial infarction, acute heart failure and arrhythmia.There was a statistically signifi cant difference in mortality among the fi ve kinds of cardiovascular emergencies accompanied with syncope(P<0.05).The mortalities of patients with syncope were significantly higher than those without syncopein AMI patients(26.53% vs.11.20%,P<0.05) and cardiac arrhythmias patients(7.04% vs.0.36%,P<0.05).The results of the CHM corrected chi square test showed that there was signifi cant difference in mortality between the syncope group and non-syncope group, when the differences in disease type, age and gender were adjusted (χ2=35.876, P<0.01). The mortality of syncope group was higher than that of non-syncope group.When age, gender and disease type were considered as covariates, the multiple logistic regression analysis showed that syncope signifi cantly increased the risk of mortality(OR=3.876,95% CI:2.362-6.359,P<0.01).Conclusion Syncope is an independent risk factor of death in patients with cardiovascular emergencies.

Objective: To understand current situation and associated factors of brucellosis infection among students in Mongolian middle school in Abaga Banner, and to provide basis for further development of prevention and treatment strategies. Methods: Serological examinations were performed on pupils and middle school students in a Mongolian middle school in Abaga Banner. Questionnaire surveys were used to investigate students knowledge of eating behaviors related to brucellosis infection. Results: A total of 500 primary and middle school students were investigated, and 6 cases of brucellosis were confirmed, and the infection rate was 1.20%. There were 4 cases of male infection and 2 cases of female infection. The infection rate in boys (1.61%) was higher than that of girls (0.79%). Higher proportion was found in 14-year-old group (n=3), accounting for 17.40%. The residence period of 10-15 years includes 6 cases of all infected persons. The number of infections in Narenbaolige Town was 4, accounting for 23.40%. Univariate logistic regression analysis shows that frequent consumption of unsterilized dairy products, milking, processing lambs or slugs and infected cloth The disease was positively correlated (OR=11.80, 139.14, 8.02, P<0.05). Multivariate Logistic regression analysis showed that milking was positively correlated with brucellosis infection(OR=20.19, 95%CI=2.01-202.74, P=0.01). Conclusion The brucellosis infection of Mongolian primary and middle school students in Abaga Banner is related to a variety of related dietary factors, and its prevention and treatment should be strengthened.

Objective:To construct a porcine model of ischemia with non-obstructive coronary artery (INOCA) and explore the diagnostic value of a one-stop noninvasive method including CT myocardial perfusion imaging (CT-MPI) and coronary CT angiography (CCTA).Methods:Twelve swines were divided into the experimental group (9) and the normal group (3). Coronary microvascular dysfunction (CMD) porcine model was constructed in the experimental group by inducing diabetes mellitus, chronic kidney disease, and hypercholesterolemia. Invasive coronary angiography (ICA) and functional examination were performed on all 7+3 trial swines to clarify the INOCA diagnosis after completion of the modeling. Then, CT-MPI and CCTA were performed on all individuals to explore the CT-MPI and CCTA characteristics of INOCA porcine models. CT-MPI parameters, including myocardial blood flow (MBF), and myocardial blood volume (MBV) in rest and stress conditions, and CCTA parameters, including severity of stenosis and CAD-RADS, were analyzed.Results:ICA and functional tests showed that all swines in the experimental group met the diagnostic criteria for INOCA, which meant that INOCA porcine model was constructed successfully. CCTA results confirmed that there was no obstructive coronary stenosis in all 10 swines which were examined, which was consistent with ICA findings. CT-MPI results demonstrated that the mean MBF values, as well as the mean MBV values, in the rest and stress condition of each swines in the experimental group were lower than those of the control group. In contrast to the control group, the mean MBF and MBV values of swines in the experimental group in stress condition were generally lower than those in resting condition.Conclusions:In this study, a porcine model of CMD is successfully constructed by inducing hypercholesterolemia+diabetes mellitus+chronic kidney disease. ICA and invasive functional tests show that this CMD model meet the diagnostic criteria for INOCA. It has been confirmed that one-stop CT multimodality examination including CT-MPI and CCTA can be used for the diagnosis of INOCA as a noninvasive diagnostic method.

Objective:To explore the difference of the vessel and plaque characteristics, myocardial perfusion and cardiac function between patients with ischemia with non-obstructive coronary artery disease (INOCA) and obstructive coronary artery disease (CAD).Methods:From July 2021 to June 2022, 101 patients with angina were referred to dynamic computed tomography myocardial perfusion (CTP) and coronary computed tomography angiography (CCTA) and retrospectively included in our hospital. Based on the results of CTP and CCTA, patients were divided into INOCA (27 cases), moderate obstructive CAD (26 cases) and severe obstructive CAD (48 cases). The anatomical coronary artery stenosis, plaque characteristics and myocardial perfusion features of all patients were analyzed. Furthermore, left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) were obtained on full-phase reconstruction CCTA image by using Medis Suite 3.2 postprocessing software. Multigroup analysis used one way ANOVA or Kruskal Wallis H test. Results:Patients with INOCA were younger than patients with moderate and severe obstructive CAD ( P<0.001). INOCA patients (7.4%, 2/27) had lower rate of positive remodeling than both moderate (57.7%, 15/26, P<0.001) and severe obstructive CAD patients (33.3%, 16/48, P=0.017). The percentage of ischemic myocardium volume in patients with INOCA were similar with those in patients with severe CAD (all P>0.05), but significantly higher than those in patients with moderate CAD (all P<0.05). No significant difference in terms of GLS was detected between patients with INOCA [-17.4% (-21.6%, -11.6%)] and severe CAD [-17.6% (-21.9%, -14.8%), P=0.536], however, patients both with INOCA and severe CAD also had higher GLS than patients with moderate obstructive CAD [-22.3% (-29.8%, -19.0%), all P<0.05]. Conclusions:Based on"one-stop-shop"CTP combined with CCTA imaging, early cardiac functional changes including abnormal myocardial perfusion and myocardial strain in INOCA patients were similar to those in patients with severe obstructive CAD and more severe than those in patients with moderate obstructive CAD.

Xiao Ke Qing (XKQ) granule has been clinically used to treat type 2 diabetes mellitus (T2DM) for 10 years in Chinese traditional medication. However, its mechanisms against hyperglycemia remain poorly understood. This study aims to investigate XKQ mechanisms on diabetes and diabetic liver disease by using the KKAy mice model. Our results indicate that XKQ can significantly reduce food and water intake. XKQ treatment also remarkably decreases both the fasting blood glucose and blood glucose in the oral glucose tolerance test. Additionally, XKQ can significantly decrease the serum alanine aminotransferase level and liver index and can alleviate the fat degeneration in liver tissues. Moreover, XKQ can ameliorate insulin resistance and upregulate the expression of IRS-1, PI3K (p85), p-Akt, and GLUT4 in the skeletal muscle of KKAy mice. XKQ is an effective drug for T2DM by ameliorating insulin resistance and regulating the PI3K/Akt signaling pathway in the skeletal muscle.
