Objective To investigate whether the cardiovascular events and prognosis on non-coronary artery disease and coronary artery disease in a period of 1 month and 6 months could be predicted by baseline levels of C-reactive protein(CRP).Methods Preprocedural serum levels of CRP were measured in 327 patients perpormed with CAG or PCI.the patients were divided into two groups: CRP

Objective To observe the clinical results of carotid artery stenting in symptomatic high-risk old patients. Methods Twenty patients who were hospitalized between 1998 and 1999 with symptomatic carotid artery stenosis were studied,retrospectively. Mean age of the patients was 70 years. 90% of patients complicated with hypertension,hyperlipidemia and severe coronary artery diseases,35% with diabetes,and 75% with peripheral artery obstructive disease. Carotid artery angiogram showed 26 lesions,7 located at right /left common carotid artery,and 19 at right/left internal carotid artery. The percentage of lumen stenosis in all lesions was greater than 70%. The mean lesion length was (14.5?9.2) mm. Results Acute procedural success rate confirmed by angiogram was achieved in all patients (100%). The minimal lumen diameter was increased from (1.9?1.2) mm at baseline to (5.9?1.4) mm post stenting ( P

Hyperthyroidism is associated with many heart diseases.Thyrotoxic state has a relationship with coronary spasm.We present a case of a non-menopausal woman with hyperthyroidism who complained of chest pain.The diagnosis of coronary spasm was confirmed by coronary angiography (CAG).She is treated well with anti-thyrotoxicosis and anti-anginal medication.We recommend not use CAG as the first diagnostic choice among the patients with medication-uncontrolled hyperthyroidism and chest pain.

OBJECTIVE: To investigate the effects of two types of temperature rinses on body temperature, inflammatory cytokine levels, and bleeding volume in percutaneous endoscopic lumbar discectomy. METHODS: Eighty patients underwent percutaneous endoscopic lumbar discectomy from January 2018 to December 2020 were selected and divided into experimental group (40 cases) and control group(40 cases). In experimental group, there were 19 males and 21 females, aged (38.8±9.8) years old;7patients on L_4,5 and 33 patients on L₅S₁;Body msss index(BMI) was (27.8±7.2) kg·m^-2. In contral group, there were 18 males and 22 females, aged (41.5±10.9) years old, 5 patients on L_4,5 and 35 patients on L₅S₁;BMI was (26.4±6.2) kg·m^-2. The patients in the control group were received normal saline rinse at room temperature, and the patients in the experimental group were received normal saline rinse heated to 37 ℃. Body temperature, chills, nausea, vomiting, and other adverse reactions were recorded. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-10 (IL-10) in two groups were recorded before and 2 hours after operation. Visual analogue scale (VAS) was used to evaluate the degree of lumbar pain in two groups before and 2 hours after surgery. Fibrinolytic-coagulation indexes with preoperative and 2 hours after surgery, including the D-dimer (DD), fibrinogen degradation products (FDP), activated partial thrombin time (APTT) and prothrombin time (PT) were recorder. Operation time and blood loss in two groups were recorded. RESULTS: The body temperature of both groups showed a downward trend, while the body temperature of the control group was lower than that of the experimental group. The levels of TNF-α, IL-6 and IL-10 in two groups were increased 2 hours after surgery compared with those before surgery(P<0.05), while the levels in experimental group were lower than those in control group(P<0.05). Postoperative VAS in experimental group 2.19±1.13 was significantly lower than that in the control group 3.38±1.35(P<0.05). The levels of DD and FDP at 2 hours after surgery in both groups were higher than those before surgery (P<0.05), while the levels of DD and FDP in the experimental group were higher than those in the control group (P<0.05). There was no significant difference in APTT and PT levels between two groups after operation (P>0.05). The blood loss in the experimental group of (45.2±14.1) ml was lower than that in the control group of (59.52±15.6) ml. The operation time of experimental group (46.7±13.8) min was less than that of control group (58.3±15.2) min(P<0.05). CONCLUSION Body temperature rinse can reduce the incidence of adverse reactions, alleviate local inflammatory reactions, reduce intraoperative blood loss and shorten the operation time.

Objective We evaluated the long term outcome of percutaneous transluminal coronary stenting in patients with unstable angina and severe ischemic left ventricular (LV) dysfunction inadequately controlled by medical therapy Methods We analyzed data on 69 lesions in 46 elective patients (66?12 years old, 72% male) with LV ejection fraction (LVEF)≤40% who presented between 1997 and 1999 and underwent coronary stenting Results Acute clinical success (

95%). Patients with overweight/obesity were more likely to have absent myocardial perfusion (MBG 0/1 grade 44.6%、64.3% and 30.6%,MBG 2/3 grade 55.4%、35.7% and 69.4% respectively, P=0.027), and absence of STR (STR

Objective In this study, we try to understand the effects of microenvironment on the differentiation of mesenchymal stem cells (MSCs) by coculturing MSCs with mature cardiomyocytes or culturing MSCs in cardiomyocyte-lysate, in this study. Methods MSCs isolated from mature rats were either cocultured with cardiomyocytes isolated from new born rats with the ratio of 1 to 4, or cultured in the medium containing 4-fold cardiomyocyte-lysate obtained by repeated freezing and defrosting of rat myocardial cells. The morphology of MSCs under light microscopy were observed daily for 7 days and immunostaining against cTnT and CD31 was performed on the 7~ th day. MSCs cultured in ordinary medium were observed as the control. Results Both MSCs cocultured with cardiomyocytes and cultured in cardiomyocyte-lysate were differentiated into myogenic cells and expressed cTnT and CD31 at the 7th day of cultivation. The MSCs in the control group did not change in morphology and express cTnT or CD31. Conclusion Both myocardial cell coculturing system and cardiomyocyte-lysate system can be used to induce bone marrow MSCs to differentiate into cardiomyocyte-like cells and endotheliocyte-like cells.

Objective To investigate the clinical features and the findings of coronary angiography,the treatment and prognosis of patients with myocardial bridge.To increase our knowledge on myocardial bridge.Methods Fifty two patients were diagnosed as myocardial bridge by coronary angiography in our hospital from January 2001 to December 2004. Angiographically,systolic compression of the arterial lumen that disappears during diastole was considered diagnostic of a myocardial bridge.Analyse the clinical features and therapy condition.Follow patients by telephone or clinical visits.Results Our study included fifty two patients.Male patients were more than female ones and the average age was 53?12 years old.Myocardial bridge was the most common in the middle segment of the left anterior descending artery.Majority of the patients took medication,and 2 of them were treated with intracoronary stent implantation.Forty patients were followed.During a mean 1.9?1.1 years follow-up period,there was no cardiac death.25 of the patients required medication,and 1 of 2 patients who underwent stent implantation had in-stent restenosis at 3.3 years.Conclusion Patients with myocardial bridge may present with atypical chest pain.Major patients with myocardial bridge are treated with medication,and stent implants may improve patients' symptoms.The prognosis of the patients with myocardial bridge is usually good.

[Summary] Rare diseases are one of the major challenges we face today in the era of precision medicine, because of the low incidence and prevalence, difficulty in diagnosis, lack of sufficient therapeutic methods, as well as their significant impacts on affected individuals, families and the society. Integration of clinical phenotypic and biological omics data and the further analysis are providing a way to illustrate the mechanisms of rare diseases, discovering novel diagnostic and prognostic biomarkers, developing orphan drugs and other therapeutics, and improving clinical outcomes and quality of life for the patients. A nation-wide registry system and the cohorts studies based on the registry are vital to the research of rare diseases. National Rare Diseases Registry System ( NRDRS) of China will provide this essential platform to promote the rare diseases research in China. With the collaboration of 20 leading medical institutes and innovation in medical informatics technologies, this system will, for the first time in China, collect the epidemiological, clinical, socio-economical, genomics and metabolomics data of more than 50 rare diseases and not less than 50 000 cases. As a national strategy for enhancing the development of medical sciences and the improvement of population health in China, NRDRS and its cohort studies will provide the pivotal support to policy making, clinical care, novel drug discovery, patient advocacy, and finally scientific progress in the field of rare diseases.
