Methods A total of 172 elderly patients who underwent coronary angiography were divided into CAD group (n = 128) and non-CAD group (n = 44) according to the results of coronary angiography. Serum FFAs and lipid levels were measured and the Gensini score were calculated. Results No matter the differences between age, gender and the usage of stat- ins or not, there was no statistical significance in FFAs levels (P 〉 0.05). In terms of the Gensini score, it was higher in patients aged 70-79 years than in patients 60-69 years old [15.00 (5.00, 34.00) vs. 10.00 (2.00, 24.00), P 〈 0.05], higher in men than women [14.00 (4.00, 34.00) vs. 7.00 (2.50, 19.75), P 〈 0.05], and higher in patients on statins [13.50 (4.25, 33.50)vs. 6.50 (2.00, 18.00), P 〈 0.05]. The serum FFAs lev- els [449.50 (299.00, 624.75) mEq/L vs. 388.00 (258.50, 495.25) mEq/L, P 〈 0.05J and Gensini score [17.50 (8.00, 41.75) vs. 1.00 (0, 5.00), P 〈 0.05] were higher in the CAD group than in the non-CAD group. In the CAD group, there was no statistical significance in FFAs levels among patients with different numbers of diseased coronary vessels (P 〉 0.05). Furthermore, the FFAs levels were positively correlated with the Gensini score (r = 0.394, P = 0.005). Regression analysis showed that the FFAs levels were related to the Gensini score independently after adjusting for the other risk factors. Conclusions The serum FFAs levels were associated with the Gensini score in elderly patients with CAD. It might indicate FFAs as a biomarker predicting the severity of coronary artery lesions.展开更多

Methods We investigated 90 participants from our institution between October 2007 to March 2010: non-DM(n = 60) and DM(n = 30). As an indicator of coronary endothelial dysfunction, we used non-invasive Doppler echocardiography to quantify coronary flow velocity reserve (CFVR) in the distal part of the left descending artery after rest and after intravenous adenosine administration. Results Plasma level of LDL-C was significantly higher in patients with DM than in non-DM (3.21 ±0.64 vs. 2.86 ±0.72 mmo/L, P < 0.05), but HDL-C level did not differ between the groups (1.01 ±0.17 vs. 1.05 ±0.19 mmo/L). Furthermore, the CFVR value was lower inDMpatients than non-diabetics (2.45 ±0.62 vs. 2.98 ±0.68, P < 0.001). Plasma levels of LDL-C were negatively correlated with CFVR in all subjects (r = ��0.35, P < 0.001; 95% confidence interval (CI): ��0.52 –��0.15) and in the non-DM(r = ��0.29, P < 0.05; 95% CI: ��0.51–��0.05), with an even stronger negative correlation in the DM group (r = ��0.42, P < 0.05; 95%CI: ��0.68 –��0.06). Age (β= ��0.019, s = 0.007, sβ= ��0.435, 95% CI: ��0.033 –��0.005, P = 0.008), LDL-C (β= ��0.217, s = 0.105, sβ= ��0.282, 95% CI: ��0.428 –��0.005, P = 0.045) remained independently correlated with CFVR in the DM group. However, we found no correlation between HDL-C level and CFVR in any group. Conclusions Diabetes may contribute to coronary artery disease (CAD) by inducing dysfunction of the coronary artery endothelium. Increased LDL-C level may adversely impair coronary endothelial function in DM. HDL-C may lose its endothelial-protective effects, in part as a result of pathological conditions, especially under abnormal glucose metabolism.展开更多

文摘Objectives To investigate the relationship between serum fxee fatty acids (FFAs) levels and the severity of coronary artery lesions in elderly patients with coronary heart disease (CAD). Methods A total of 172 elderly patients who underwent coronary angiography were divided into CAD group (n = 128) and non-CAD group (n = 44) according to the results of coronary angiography. Serum FFAs and lipid levels were measured and the Gensini score were calculated. Results No matter the differences between age, gender and the usage of stat- ins or not, there was no statistical significance in FFAs levels (P 〉 0.05). In terms of the Gensini score, it was higher in patients aged 70-79 years than in patients 60-69 years old [15.00 (5.00, 34.00) vs. 10.00 (2.00, 24.00), P 〈 0.05], higher in men than women [14.00 (4.00, 34.00) vs. 7.00 (2.50, 19.75), P 〈 0.05], and higher in patients on statins [13.50 (4.25, 33.50)vs. 6.50 (2.00, 18.00), P 〈 0.05].

In the CAD group, there was no statistical significance in FFAs levels among patients with different numbers of diseased coronary vessels (P 〉 0.05). Furthermore, the FFAs levels were positively correlated with the Gensini score (r = 0.394, P = 0.005). Regression analysis showed that the FFAs levels were related to the Gensini score independently after adjusting for the other risk factors. Conclusions The serum FFAs levels were associated with the Gensini score in elderly patients with CAD. It might indicate FFAs as a biomarker predicting the severity of coronary artery lesions.

文摘The core treatment of rapid arrhythmiainduced heart failure(HF)is to control the ventricular rate to an optimized lower level,which is usually achieved with various anti-arrhythmic drugs.However,arrhythmias may not respond well to pharmaceutical treatment for various reasons.Iatrogenic atrioventricular(AV)node ablation needs to be performed under these extreme conditions to lower the patient’s heart rate.
文摘Objectives To evaluate the association of coronary artery endothelial function and plasma levels of low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) in patients with Type 2 Diabetes Mellitus (DM). Methods We investigated 90 participants from our institution between October 2007 to March 2010: non-DM(n = 60) and DM(n = 30). As an indicator of coronary endothelial dysfunction, we used non-invasive Doppler echocardiography to quantify coronary flow velocity reserve (CFVR) in the distal part of the left descending artery after rest and after intravenous adenosine administration. Results Plasma level of LDL-C was significantly higher in patients with DM than in non-DM (3.21 ±0.64 vs. 2.86 ±0.72 mmo/L, P < 0.05), but HDL-C level did not differ between the groups (1.01 ±0.17 vs. 1.05 ±0.19 mmo/L). Furthermore, the CFVR value was lower inDMpatients than non-diabetics (2.45 ±0.62 vs. 2.98 ±0.68, P < 0.001). Plasma levels of LDL-C were negatively correlated with CFVR in all subjects (r = ��0.35, P < 0.001; 95% confidence interval (CI): ��0.52 –��0.15) and in the non-DM(r = ��0.29, P < 0.05; 95% CI: ��0.51–��0.05), with an even stronger negative correlation in the DM group (r = ��0.42, P < 0.05; 95%CI: ��0.68 –��0.06). Age (β= ��0.019, s = 0.007, sβ= ��0.435, 95% CI: ��0.033 –��0.005, P = 0.008), LDL-C (β= ��0.217, s = 0.105, sβ= ��0.282, 95% CI: ��0.428 –��0.005, P = 0.045) remained independently correlated with CFVR in the DM group. However, we found no correlation between HDL-C level and CFVR in any group. Conclusions Diabetes may contribute to coronary artery disease (CAD) by inducing dysfunction of the coronary artery endothelium. Increased LDL-C level may adversely impair coronary endothelial function in DM. HDL-C may lose its endothelial-protective effects, in part as a result of pathological conditions, especially under abnormal glucose metabolism.
文摘It has been reported that up to 12% of patients underwent non-cardiac surgery or invasive procedures within the first year after the coronary stent implantation. Premature dis- continuation of antiplatelet therapy is associated with a sig- nificant increase in mortality and major adverse cardiac events, in particular, stent thrombosis. Thus, postpone- ment of elective surgery is advocated during the first year after the coronary stent implantation.

文摘BACKGROUND Germinoma is a type of germ cell tumor that most frequently arises in the midline axis of the brain.Impaired vision is a clinical manifestation of germinnoma.Although rare,intracranial germinoma seeding to the perioptic arachnoid space is one cause of visual acuity decrease.CASE SUMMARY An 11yearold girl who presented with polyuria and polydipsia and subsequently developed diminution of vision.Imaging showed bilateral heterogeneous enhancement of the optic nerve sheaths and atrophy of the optic nerve,and transsphenoidal biopsy revealed a germinoma.The patient experienced poor visual recovery following chemotherapy and radiotherapy.Germinomas are rare and they are mostly identified in children and adolescents.The manifestations include diabetes insipidus,pituitary dysfunction,visual complaints,etc.The mechanisms that lead to visual loss include intracranial hypertension,compression of optic chiasma,and tumor invasion.A literature review was performed to summarize the cases with a tumor infiltrating the optic nerve.Most of the reported patients were adolescents and presented with anterior pituitary hormone deficiency.Enhancement of optic nerve sheaths and optic disc pallor could be identified in most of the cases.The purpose of this report is to provide awareness that in cases where a germinoma is associated with visual loss,though rare,perioptic meningeal seeding should be taken into consideration.CONCLUSION The case report suggests that children with diabetes insipidus need a complete differential diagnosis.
文摘We searched PVS-related literature in the Web of Science Core Collection database,extracted and analyzed the data using the Science Citation Index Extended Edition,and included two types of literature:review and monograph.The search terms were subject=persistent vegetative state and publication year(2001-2021)and language=English.Statistical analysis of literature overview,countries and regions,institutions,authors,literature source publications,literature research direction,citation frequency,impact factor,H-index and keywords,etc.are carried out.Use VOS viewer 1.6.17 software to visually cluster the keywords in the titles and abstracts of the included literature and analyze the research direction and development trend.A total of 772 PVS-related documents published in the core collection database of Web of Science from 2001 to 2021 were included.The country with the largest number of publications was the United States(261 papers,33.80%),and the institution with the largest number of publications was the University of Liège,Belgium(40 papers,5.18%).The author with the largest number of published papers is Laureys S of the University of Liège,Belgium(39 papers,5.05%).The research directions of PVS are mainly neuroscience(350 articles,45.33%),rehabilitation(98 articles,12.69%),and internal medicine(9 articles,11.79%).The literature is mainly from Brain Injury.The annual average impact factor of the top 10 journals in 2020 was 4.55,and their publication volume accounted for 17.35%(134/772)of the total literature.The 772 articles were cited 23,503 times(21,400 self-citations were excluded),with an average of 30.44 citations per article.The H-index of the United States,the United Kingdom and Belgium are 48,27 and 27,which are significantly higher than other countries,and the citation frequencies are 8609,3451 and 3270,accounting for 36.60%,14.68%and 13.90%of the total citations,respectively.China's publication volume is in the middle,but only 8th in citation frequency and H-index(818 citations,H-index 16).We used the VOS viewer software to analyze and found that the keywords were mainly concentrated in four groups:"diagnosis-related","treatment-related","prognosis-related"and"disease-related".From 2001 to 2021,the United States,Italy and the United Kingdom have the largest number of PVS related literature publications.There is still a certain gap between China and western countries in terms of the number and quality of literature publications.

文摘To solve the problem of low reduction extraction rate of zinc from blast furnace dust,the effects of CacO3 addition,reduction temperature,and reduction time on self-reduction zinc extraction were studied through high-temperature reduction experiment,and the mechanism of how CaCO_(3) addition promotes zinc ferrite reduction was analyzed.The zinc removal rate can reach 98.82%when the blast furnace dust is reduced at 1000℃ for 25 min by adding 10 mass%CaCO_(3).At low temperature,CaCO_(3) can enhance the reduction and decomposition of ZnFe_(2)O_(4)(which is difficult to reduce)into ZnO and low-valent iron oxides.After CaCO_(3) is decomposed at high temperature,CO_(2) is produced to undergo gasification reaction with carbon in blast furnace dust,and co is generated to provide more reducing agents for the whole reduction system.CaO generated by decomposition can also catalyze the gasification reaction of carbon,thus improving the removal rate of zinc in the reduction process of dust.
