Objectives:To establish a comprehensive system of Cardiovascular Academic Performance Evaluation(CAPE)and rank global TOP100 medical institutions in the fields of cardiovascular diseases(CVD). Methods:CVD-related terms were extracted from Medical Subject Headings(MeSH),Embase thesaurus(EMtrees)and International Classification of Diseases(ICD)by CVD-related professionals,as well as by librarians and information professionals.Terminology databases(named as Fuwai Subject Headings)were established,and nine sub-disciplines were proposed,including ischemic heart diseases,hypertension,vascular diseases,arrhythmia,pulmonary vascular diseases,heart failure,congenital heart diseases,cardiomyopathy,and valvular heart diseases.The mapping patterns of sub-discipline,cardiovascular terminology and entry terms were pre-defined.The CVD-related research literature published from January 1,2016 to December 31,2022 were retrieved from Web of Science,PubMed and Scopus.Based on this,metadata were fused and duplicates were excluded.Fuwai Subject Headings were searched and matched into four respects for each literature,including subject words,titles,keywords,and abstracts,which was used to generate an information table of"Position—CVD terminology—Frequency",and to calculate CVD correlation scores and sub-discipline scores.We standardized the names of medical institutions and scholars,and make a ranking system for CAPE based on original articles with strong cardiovascular correlation(correlation score≥4).When evaluating the science and technological performance for Chinese hospitals in cardiovascular diseases,National Natural Science Foundation Projects,authorized invention patents,prize achievements,research platforms,and registered data of drug clinical trials in Center for Drug Evaluation(CDE)were considered besides research papers. Results:During 2016 and 2022,1 545 103 CVD research literatures were found worldwide.After excluding meeting abstracts,books,biographies,news,videos,audio texts,retracted publications,and corrections,1 178 019 CVD research literatures were further evaluated.518 058 literatures were indexed as"strongly correlated to CVD"using Fuwai Subject Headings.Besides papers,other data sources were also collected,including 11 143 CVD-related Natural Science Foundation Projects,19 382 CVD-related effective authorized invention patents,103 CVD-related national prize achievements,24 CVD-related national research platforms,and 2 084 CDE registered data of CVD-related drug clinical trials.Research teams from nine sub-disciplines reviewed and validated research literature in respective fields,and classification rules of corresponding sub-disciplines were created and improved based on their opinions.Finally,eleven individual indexes were chosen to construct CAPE system for ranking global TOP100 medical institutions in overall CVD field and TOP30 in nine sub-disciplines.From 2016 to 2022,the number of cardiovascular disease research papers published by Chinese institutes has increased by 123.5%,with a total of approximately 76.8 thousands papers published(about 30 papers per day on average),ranked the second under the United States(approximately 114.1 thousands papers).However,the proportion of papers published by the Chinese Journal Citation Reports(JCR)and the Chinese Academy of Sciences only ranked eighth in the world.In the comprehensive academic performance of original cardiovascular research papers in global hospitals from 2020 to 2022,only two Chinese medical institutions ranked in the TOP20 as evaluated by CAPE system. Conclusions:Based on multi-source data from 2016 to 2022,CAPE initiated to establish a cardiovascular academic performance evaluation system.

Objectives:To compare the patent protection and application status of cardiovascular technology innovation in ten major countries worldwide from 2016 to 2023,and to analyze and evaluate the relative competitiveness and innovation ability of technology achievements in the cardiovascular fields in China,providing reference for improving the transfer and transformation rate of scientific and technological achievements in this field. Methods:Based on the HimmPat,IncoPat,and Wisdom Seed patent databases,using the Fuwai Subject Headings,we searched patent application data in the cardiovascular fields from ten major countries worldwide from January 1,2016 to December 31,2023 by adopting the method of the International Patent Classification(IPC)-Title-Claims-Abstract.We compared and analyzed specific indicators from the three dimensions of the patent,including technology value,legal value,and economic value. Results:Over the past eight years,the total number of patent applications in the cardiovascular fields was counted from the perspective of patent applicant addresses to analyze the technological innovation capabilities in cardiovascular field of each country.The results showed that China ranked the second in the world in terms of the total number of patent applications in the cardiovascular fields,with approximately 46 536,followed the United States with 75 382.Although the number of patent family applications in China is higher than that in the United States(32 879 vs.19 587),overseas applications for family patent in China only account for 25.4%of its total patent application volume,which is only higher than that in Russia(15.5%),while much lower than that in the other eight countries.In terms of the average number of patent applicants,there are only 2.61 applicants per patent in China,compared with 10.02 in the United States and 12.69 in Germany.In terms of citation frequency of simple patent family,the United States has 9.76 citations per patent,while China has only 2.64 citations per patent.Besides,the patent transfer rate in China is also relatively low with a proportion of only 7.3%. Conclusions:The economic development,government policy support and technological advancement jointly contribute to the continuously increased number of cardiovascular patent applications in China.However,the patents are associated with poor quality,insufficient overseas layout,and insufficient horizontal cooperation in technological innovation,which may also be the main reasons for the insufficient momentum and efficiency of patent achievement transformation.

Objectives:To investigate the clinical impacts of chronic total occlusion (CTO) in acute non-ST segment elevation myocardial infarction (NSTEMI) patients underwent primary percutaneous coronary intervention (PCI).Methods:A total of 2 271 acute NSTEMI patients underwent primary PCI from China Acute Myocardial Infarction Registry were enrolled in this study and divided into the CTO group and the non-CTO group according to the angiography. The primary endpoint was in-hospital mortality and mortality during a 2-year follow-up. The secondary endpoint was major adverse cardiovascular events (MACE) including revascularization, death, re-myocardial infarction, heart failure readmission, stroke and major bleeding.Results:Thirteen-point four percent of the total acute NSTEMI patients had concurrent CTO. In-hospital mortality (3.6% vs. 1.4%, P<0.01) and 2-year mortality (9.0% vs. 5.1%, P<0.01) were significantly higher in the CTO group than those in the non-CTO group, respectively. Multiple regression analyses showed that chronic obstructive pulmonary disease ( HR 7.28, 95% CI 1.50-35.35, P=0.01) was an independent risk factor of in-hospital mortality, and advanced age ( HR 1.04, 95% CI 1.01-1.07, P<0.01), and low levels of ejection fraction ( HR 0.95, 95% CI 0.93-0.98, P<0.01) were independent risk factors of 2-year mortality. CTO ( HR1.67, 95% CI 1.10-2.54, P=0.02) was an independent risk factor of revascularization, but not a risk factor of mortality. Conclusions:Although acute NSTEMI patients concurrent with CTO had higher mortality, CTO was only an independent risk factor of revascularization, but not of mortality. Advanced age and low levels of ejection fraction were independent risk factors of long-term death among acute NSTEMI patients.

Objective:To reveal the mechanism of Mahuang Lianqiao Chixiaodou decoction and its disassembled formula for improving the skin barrier function in a mouse model of atopic dermatitis (AD).Methods:Sixty specific-pathogen free male BALB/c mice were randomly divided into the control group,model group,whole formula group (WF),exterior-releasing formula group (ERF),interior-clearing for-mula group (ICF),and positive control group (PC).A mouse model of AD was established using the semi-antigen 2,4-dinitrofluorobenzene induction method.The lesion scores,transepidermal water loss and pH,and skin histopathology of mice in each group were observed.The expressions of filaggrin,loricrin,and involucrin were detected by the streptavidin peroxidase immunohistochemical method and western blotting,and their mRNA expressions were detected by quantitative polymerase chain reaction.Results:Mice in the WF,ERF,ICF,and PC groups showed reduced skin lesion performance,improved histopathology,decreased skin lesion score,transepidermal water loss and pH,and upregulated ex-pressions of proteins including filaggrin,loricrin,and involucrin,and their mRNAs.The most obvious regulatory effect was observed in the WF group,followed by the ICF,ERF,and PC groups,accordingly.Conclusions:Mahuang Lianqiao Chixiaodou decoction and its disassembled formula can improve the skin barrier function in a mouse model of AD by upregulating filaggrin,loricrin,and involucrin,and their mRNA expressions,and the most optimal effect was noted in the WF group,followed by the ICF and ERF groups,which suggests that the effect of clearing heat and resolving dampness in improving the skin barrier function of AD is more obvious and is one of the key treatments for AD.

Objective:To comprehensively analyze the medical resources and services supply in the cancer field of China.Methods:Data of 2018 were sampled from 41 tertiary public cancer hospitals in China, and the factor analysis method was used to extract common factors in resources or services, scoring respectively. Pearson correlation analysis was used in the collinearity test of the variables of both groups of common factors, while the second-order clustering method was used to analyze characteristic differences between the hospitals, and category difference was compared with t test. Results:Resource evaluation covered the two dimensions of basic resources(medical service and basic assurance resources)and high-end resources(high-end talents and academic resources). Service evaluation covered the two dimensions of medical service assurance(clinical services and basic assurance)and disciplinary sphere of influence(discipline construction and clinical efficiency). The factor of basic manpower and beds was significantly correlated with that of medical service and basic assurance( r=0.811, P<0.001), while the factor of high-end talents and academic resources was significantly correlated with that disciplinary construction and resource efficiency( r=0.906, P<0.001). The second-order cluster analysis found the 41 cancer hospitals as two categories, with the first category of five in Guangdong, Shanghai, Beijing and Tianjin, and the second category of the rest 36 hospitals. Significant differences were found between the two categories in terms of resource scoring, service scoring, high-end resources and disciplinary sphere of influence( P<0.001). Meanwhile, the GDP per capita of the cities in which these hospitals are located also had significant differences( P<0.001). Conclusions:Development of public tertiary cancer hospitals in China was imbalanced, as their differences were mainly found in levels of disciplinary development and efficiency of clinical services, which were closely related to the high-end talents and academic resources of the hospital in question.Furthermore, high quality medical care was mostly located in regions of higher development. The authors recommend to take a balanced consideration of the differences and distribution of cancer care services in China, in terms of performance classification of public hospitals and establishment of regional cancer centers of the country.

Objective: To evaluate the prognostic value of the thrombolysis in myocardial infarction (TIMI) and global registry of acute coronary events (GRACE) risk scores for in-hospital mortality in Chinese non-ST-segment elevation myocardial infarction (NSTEMI) patients. Methods: Data of present study derived from the prospective, multi-center registry trial of Chinese AMI (CAMI). Among 31 provinces, municipalities or autonomous districts in China, at least one tertiary and secondary hospital was selected. From January 2013 to September 2014, 5 896 consecutive non-ST-segment elevation myocardial infarction patients who were admitted to 107 hospitals within 7 days of symptom onset were enrolled. For each patient, TIMI and GRACE risk scores were calculated using specific variables collected at admission. Their prognostic value was evaluated by the endpoint of in-hospital mortality. Results: Among 5 896 NSTEMI patients (age was (65.4±12.1) years old), 68.2% (n=4 020) were males. The in-hospital mortality was 6.0% (n=353) and the median length of hospital stay was 10.0 (7.0, 13.0) days. The incidence of pre-hospital cardiac arrest was 3.6% (n=213) among 5 896 NSTEMI patients. Six hundreds and forty five patients (10.9%) received primary percutaneous coronary intervention, and 6 patients underwent emergent coronary artery bypass grafting surgery (0.1%), and the median time of reperfusion was 529.5 (256.0, 1 065.0) minutes. The prescription percentage of statins, β-blocker, angiotensin converting enzyme inhibitors or angiotensin Ⅱ receptor blockers, and aldosterone antagonists were 94.8% (n=5 587), 71.7% (n=4 228), 65.5% (n=3 864) and 26.0% (n=1 533) respectively. The area under the curve of GRACE risk score for in-hospital mortality (0.7930 (95%CI 0.767-0.818)) was better than that of TIMI risk score (0.5588 (95%CI 0.532-0.586), P<0.001). Conclusion GRACE risk score demonstrates better predictive accuracy than TIMI risk score for in-hospital mortality in NSTEMI patients in this patient cohort.

BACKGROUND AND OBJECTIVES: Over the past decades, transradial approach for percutaneous coronary intervention (PCI) has been increasingly adopted in clinical practice. Women represent a large population who will possibly benefit from PCI, but they are often under-represented in clinical studies. Therefore, the role of TRI in women remains to be further defined. This study sought to compare safety and efficacy for transradial intervention (TRI) and transfemoral intervention (TFI) in women undergoing PCI in China. METHODS: The study population consisted of 5,067 women undergoing PCI at Fuwai Hospital, Beijing, China between 2006 and 2011 (TRI: n=4,105, TFI: n=962). Incidence rates of clinical outcomes during hospitalization and at 1-year follow-up were compared between TRI and TFI. In order to minimize potential biases, a 1:1 propensity score matching (PSM) was performed. A total of 899 pairs were matched. RESULTS: Baseline and procedural characteristics were well-balanced between TRI and TFI groups after controlling for confounders using PSM. TRI was associated with reduced major post-PCI bleeding (odds ratio [OR], 0.64; 95% confidence interval [CI], 0.54–0.76; p < 0.001) and access site complications (OR, 0.67; 95% CI, 0.61–0.74; p < 0.001) after PSM. There was no statistical differences in the incidence rates of major adverse cardiac events (a composite of cardiac death, myocardial infarction, and target vessel revascularization) both during hospitalization and at 1-year follow-up (p > 0.05). CONCLUSIONS: In this propensity score-based analysis of TRI versus TFI in Chinese women, TRI showed advantages of safety and feasibility over TFI. A wider adoption of TRI in women has the potential to improve outcomes in treatment of coronary artery diseases.

Objective To study the mechanism of anti-inflammation and bacteriostasis effect of Qinlian Liyan Heji. Methods To assess the anti-inflammatory effect, blood capillary permeability in mice was increased by acetic acid, the swelling of toe in rats was induced by albumen, and granuloma was induced by cotton ball in mice.The agar dilution method was used to check the minimal inhibitory concentration of Qinlian Liyan Heji on Staphylococcus aureus, Staphylococcus epidermidis, Moraxella catarrhalis, Klebsiella pneumoniae.The microdilution method was used to detect the minimal inhibitory concentration of Qinlian Liyan Heji on group A streptococci, Streptococcal pneumonia and Haemophilus influenzae. Results Contrast to the negative control group, Qinlian Liyan Heji significantly inhibited the increase of blood capillary permeability caused by acetic acid in the middle dose and the high dose groups.In the low dose and middle dose groups, Qinlian Liyan Heji obviously reduced the swelling of plantar in 2, 3, 4, 5 h.In the high dose group, Qinlian Liyan Heji markedly lowered the swelling of plantar in 1, 2, 3, 4, 5 h. Qinlian Liyan Heji significantly reduced the granuloma caused by cotton ball. On the other hand, Qinlian Liyan Heji exerted bacteriostatic effect on the above 7 types of bacteria. Conclusion Qinlian Liyan Heji has effects of anti-inflammation and bacteriostasis.

Objective To investigate the relationship between plasma albumin and hemoglobin(Hb) levels and prognosis in patients with severe craniocerebral trauma. Methods The clinical data of 124 patients with severe craniocerebral trauma form January 2010 to January 2014 were analyzed retrospectively. The relationship between plasma albumin and Hb levels and prognosis were analyzed. Hb level was obtained in 3 days of admission, and then the patients were divided into Hb <90 g/L group, Hb 90-99 g/L group, Hb 100-110 g/L group, Hb >110 g/L group, and also were albumin <25 g/L group, albumin 25-28 g/L, albumin 29-31 g/L group, albumin>31 g/L group according to the mean albumin level. Multifactor Logistic regression analysis was used to analyze the relationship between Hb, albumin levels and prognosis. Results Among 124 patients, 37 patients (29.8%) were given red blood cell (RBC) transfusion, and 28 patients (22.6%) received albumin treatment. The hospital mortality was 20.2% (25/124). The age, scores of Glasgow Coma Scale (GCS) and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ ), and hospital mortality in different Hb level groups had no significant differences (P>0.05). The age, scores of GCS score and APACHEⅡ score in different albumin level groups had no significant differences (P>0.05), but the hospital mortality in different albumin level groups had significant difference: 31.2%(10/32), 24.2%(8/33), 9.7%(3/31), 14.3%(4/28), P<0.05. Multifactor Logistic regression analysis showed that albumin level was the relevant factor for the severe craniocerebral trauma (P<0.01), the hospital mortality was decreased with the rising of the albumin level, but the risk of death was higher in albumin>31 g/L group than that in albumin 29-31 g/L group. Conclusions 29-31 g/L albumin level is the best for severe craniocerebral trauma patients. There is no significant impact of Hb on the prognosis for severe craniocerebral trauma patients.
