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.

Epilepsy is an episodic, transient, stereotypic brain dysfunction caused by highly synchronized abnormal neuronal discharges in the brain, with unpredictable timing of seizures, for which the main treatment modalities are antiepileptic drugs and surgery. Its diagnosis and treatment require a large number of aids and clinical experience. For multiple clinical aspects of epilepsy, such as seizure prediction, drug therapy prognosis, and surgical treatment evaluation, machine learning can incorporate multiple clinical and imaging factors through deep mining of data, establish corresponding learning models, improve the efficiency and accuracy of epilepsy diagnosis, realize individualized application of antiepileptic drugs, and improve the preoperative evaluation and prognosis of epilepsy patients.

BACKGROUND:Unicompartmental knee arthroplasty has been paid more and more attention because of its advantages of fewer traumas,less blood loss,less complications,faster recovery,excellent knee function and high prosthetic survival rate.Most of the relevant reports focused on its clinical effect,but the changes in the levels of relevant inflammatory cytokines in patients after unicompartmental knee arthroplasty were rarely reported. OBJECTIVE:To investigate the effect of unicompartmental knee arthroplasty in patients with medial compartment osteoarthritis of the knee and the changes of interleukin-1,interleukin-6,and tumor necrosis factor-α levels. METHODS:A total of 30 patients with medial compartment osteoarthritis of the knee who received unicompartmental knee arthroplasty from September 2021 to March 2023 and met the inclusion criteria were selected as the study subjects.Medial angle of proximal tibia,femoral and tibial angle,pain visual analog scale score,hospital for special surgery score,knee joint range of motion,synovial fluid interleukin-1,interleukin-6,and tumor necrosis factor-α levels before and after surgery were compared and statistically analyzed. RESULTS AND CONCLUSION:(1)All 30 patients had grade I wound healing.All patients were followed up for more than 6 months after surgery.There were no complications such as prosthesis loosening and dislocation of prosthesis liner in all patients.(2)The medial proximal tibia angle and the femoral and tibial angles measured after operation were significantly improved(P<0.05).(3)The visual analog scale score,hospital for special surgery score and range of motion measured at 1,3,and 6 months after operation were better than those before operation(P<0.05),and showed a gradual improvement(P<0.05).(4)The levels of interleukin-1,interleukin-6,and tumor necrosis factor-α in synovial fluid at 3 and 6 months after operation were decreased gradually compared with those before operation(P<0.05)and showed a gradual downward trend at each time point after operation.(5)It is indicated that unicompartmental knee arthroplasty can effectively treat medial compartment osteoarthritis of the knee,significantly relieve pain,restore knee joint function,improve knee varus deformity and lower limb strength line,and reduce the levels of inflammatory cytokines interleukin-1,interleukin-6,and tumor necrosis factor-α in joints to a certain extent.

Objective:Analysis of the influencing factors of maternal oral health care behavior based on the health belief model.Methods:From July to December 2023, a cross-sectional survey was conducted in Peking Union Medical College Hospital on 316 pregnant women who received the health belief questionnaire and self-efficacy scale。 t test and χ2 test were used to analyze the factors affecting the oral health care behavior of pregnant women from the perspective of social psychology. Results:Among the 316 pregnant women included, 110(34.8%) had poor daily oral health care behavior, 120 (38.1%)did not have oral examination before or during pregnancy. The health beliefs of pregnant women in overall oral care were not high, with a score of 6.63+3.23, Median score is 7 (5).Perceived susceptibility to oral diseases ( OR=1.51, 95% CI:1.026-2.213), self-efficacy of daily living ( OR=2.64, 95% CI: 1.384-5.040), self-efficacy of oral examination ( OR=1.74, 95% CI:1.184-2.570) were independent factors of daily oral health care behavior in pregnant women. Health motivation ( OR=2.47, 95% CI:1.474-4.126) and self-efficacy of oral examination ( OR=4.17, 95% CI:2.626-6.619) were independent factors of oral examination behavior before and during pregnancy. Conclusion:Health beliefs of maternal oral health, especially perceived susceptibility, health motivation and self-efficacy are closely related to maternal oral health care behaviors. To improve the health belief and self-efficacy of pregnant women′s oral health care and avoid potential obstacles, which could be conducive to the effective promotion of oral health care for pregnant women.

Objective:To explore the clinical and genetic characteristics of a child with autosomal recessive primary microcephaly (MCPH).Methods:A case study has been carried out on a boy who had presented at the Inner Mongolia Maternity and Child Health Care Hospital for microcephaly and mental deficiency in September 2022. Prenatal ultrasound images were retrospectively analyzed, and whole exome sequencing and Sanger sequencing were carried out for his family. A literature review was also carried out using keywords such as " ASPM gene", "microcephaly", "prenatal diagnosis", "primary microcephaly", " ASPM", "MCPH5", "MCPH", "autosomal recessive microcephaly", and "prenatal diagnosis on ultrasonography" on the PubMed database, Wanfang Data and China National Knowledge until September 2023. This study was approved by Medical Ethics Committee of the Inner Mongolia Maternity and Child Health Care Hospital (Ethics No. 2021-093-1). Results:The proband had shown progressive reduction in biparietal diameter (BPD) and head circumference (HC) during the fetal period. He was found to harbor compound heterozygous variants of the ASPM gene, which included a paternally derived c. 8044C>T (p.R2682X) and a maternally derived c.8652dup (p.A2885Sfs*35). Both variants were classified as pathogenic (PVS1+ PM2_Supporting+ PP4; PVS1+ PM2_Supporting+ PM3) based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). For other fetuses in his family, prenatal ultrasound and genetic testing were all normal. Literature research has identified 11 relevant articles, which included 14 MCPH cases. All of the MCPH5 cases had shown various degrees of reduced BPD/HC on fetal imaging (100%, 15/15). Developmental delay, intellectual disability, and attention deficits were noted in all survived cases, with one case having seizures (12.5%, 1/8). Their genotypes had included homozygotes (46.2%, 6/13) and compound heterozygotes (53.8%, 7/13) for nonsense variants (45%, 9/20) and frameshifting variants (55%, 11/20). Conclusion:The compound heterozygous variants c. 8044C>T (p.R2682X) and c. 8652dup (p.A2885Sfs*35) of the ASPM gene probably underlay the reduced BPD and HC in this proband with MCPH.

Objective:To investigate the effects of overexpression of Nkx2.5 gene on the anti apoptotic ability of bone marrow mesenchymal stem cells (BMSCs) and cardiac function after myocardial infarction.Methods:A cell ischemia model was established by culturing cells under oxygen glucose deprivation/reoxygenat (OGD/R) conditions. The experiment was divided into four groups: bone marrow mesenchymal stem cells cultured under normal conditions (BMSC group), BMSC group cultured under glucose and oxygen deprivation (BMSC+OGD/R group), overexpressed empty vector BMSC group cultured under glucose and oxygen deprivation(BMSC NC+OGD/R group), and overexpressed Nkx2.5 BMSC group cultured under glucose and oxygen deprivation (BMSC Nkx2.5+OGD/R group). The apoptosis rate of BMSCs in each group was detected via flow cytometry, and BMSC protein was extracted. The expression of caspase-3 and pro-caspase-3, caspase-8 and pro-caspase-8, caspase-9, and cytochrome C protein and expression of Nkx2.5 in the BMSCs of each group were detected by Western blot to determine the anti-apoptotic pathway in vitro. The model of myocardial infarction in mice was established by ligating the left anterior descending branch of coronary artery. The experiment was divided into five groups: sham surgery group, myocardial infarction untreated group, myocardial infarction tail vein injection of BMSC group, myocardial infarction tail vein injection of BMSC empty body group, myocardial infarction tail vein injection of BMSC overexpression Nkx2.5 group. The changes of cardiac function in mice were evaluated by echocardiography. Normal distribution econometric data were compared between groups using convenient analysis, and pairwise comparisons were conducted using LSD-t test. Results:The apoptosis rate of the BMSC+OGD/R group (12.98±1.24)% was higher than that of the BMSC group (7.82±0.42)%, and the difference was statistically significant ( P<0.001). The apoptosis rate of the BMSC NKx2.5+OGD/R group (11.26±0.22)% was lower than that of the BMSC+OGD/R group (12.98±1.24)% and the BMSC NC+OGD/R group (13.14±0.70)%, with statistically significant differences ( P<0.05). Compared to BMSC group ((0.36±0.08), (1.13±0.04), (0.36±0.06), (1.12±0.13), (1.23±0.08), (0.60±0.05), (0.67±0.14)), BMSC+OGD/R group ((1.05±0.10), (0.62±0.04), (1.07±0.09), (0.57±0.07), (0.55±0.08), (1.25±0.09), (0.71±0.04)) and BMSC NC+OGD/R group ((1.16±0.16), (0.64±0.06), (1.19±0.16), (0.56±0.06), (0.50±0.06), (1.28±0.06), (0.73±0.04)), the expression of Caspase-3 (0.72±0.08) and pro-caspase-3(0.89±0.09), Caspase-8 (0.63±0.08) and pro-caspase-8(0.85±0.12), Caspase-9 (0.87±0.09), cytochrome C (0.91±0.10), and Nkx2.5 (1.54±0.16) in BMSC Nkx2.5+OGD/R group was statistically significant (all P<0.05). In vivo experiments showed that the heart ejection fraction (29.05±7.07)% of mice treated with BMSC Nkx2.5 after myocardial infarction was significantly improved compared to the BMSC group (16.57±2.09)% and BMSC NC group (18.08±3.27)% (all P<0.05). Conclusion:BMSC Nkx2.5 may enhance the anti-apoptosis ability of BMSCs and improve cardiac function after myocardial infarction by inhibiting the death receptor pathway and the mitochondrial signal pathway .
