BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Elemene is widely recognized as an effective anti-cancer compound and is routinely administered in Chinese clinical settings for the management of several solid tumors, including non-small cell lung cancer (NSCLC). However, its detailed molecular mechanism has not been adequately demonstrated. In this research, it was demonstrated that elemene effectively curtailed NSCLC growth in the patient-derived xenograft (PDX) model. Mechanistically, employing high-throughput screening techniques and subsequent biochemical validations such as microscale thermophoresis (MST), microRNA-145-5p (miR-145-5p) was pinpointed as a critical target through which elemene exerts its anti-tumor effects. Interestingly, elemene serves as a binding stabilizer for miR-145-5p, demonstrating a strong binding affinity (dissociation constant (K _D) = 0.39 ± 0.17 μg/mL) and preventing its degradation both in vitro and in vivo, while not interfering with the synthesis of the primary microRNA transcripts (pri-miRNAs) and precursor miRNAs (pre-miRNAs). The stabilization of miR-145-5p by elemene resulted in an increased level of this miRNA, subsequently suppressing NSCLC progression through the miR-145-5p/mitogen-activated protein kinase kinase kinase 3 (MAP3K3)/nuclear factor kappaB (NF-κB) pathway. Our findings provide a new perspective on revealing the interaction patterns between clinical anti-tumor drugs and miRNAs.

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.

Conclusions:Drug balloon therapy for de novo coronary chronic occlusive lesions is safe and effective,and the prognosis is satisfactory.

It is believed that traditional Chinese medicine （TCM） Daoyin （conduction exercise） therapy has potential in treating diabetic foot， which is a concrete embodiment of HUANG Yuanyu's theory of one qi circulation applied in practice. Based on Daoyin therapy of Baduanjin and the Origin and Indicators of Disease （《诸病源候论》）， a Daoyin prescription for diabetic foot was compiled and created. Based on the zang-fu concept of "One Qi Circulation"， combined with the theory of chief， deputy， assistant and envoy， this article explained the theoretical basis and functional mechanism of the Daoyin prescription for diabetic foot. This Daoyin therapy is mainly based on the prone position movements， which includes seven movements， namely， pull-up， knee bending， toe tilting， phoenix nodding， internal rotation of taiji， two hands climbing feet and closing. With "phoenix nodding" and "tilting toes" as the chief， with the help of toes opening-closing and pointing-pressing momentum in prone position， regulating the central qi； with "bending the knee" and "internal rotation of taiji" as the deputy， knee and ankle flexion and extension can unblock the meridians of liver and lungs； with "pull-up" and "two hands climbing feet" as the assistant， on the one hand， assisting to unblock zang-fu organs， on the other hand， applying the yang of the foot taiyang bladder channel and du mai to warm the cold and dampness； with "closing" as the envoy to regulate all organs， so that the blood return to the natural flow of circulation. Diabetic foot Daoyin therapy could regulate internal organs and qi circulation of body， and provides a new idea for the treatment of diabetic foot.

Objective To investigate the effect of early active cycle breathing technique(ACBT)on aspiration in patients with dysphagia after partial laryngectomy.Methods A total of 40 patients with laryngeal cancer with dysphagia who were hospitalized in the Department of Otorhinolaryngology of the Third Xiangya Hospital of Central South University in January 2019～January 2022 were selected,and the patients were randomly divided into 20 cases in the observation group and the control group by random number method,the control group was given routine swallowing function training,and the observation group was combined with active cycle of breathing technique(ACBT)on the basis of the control group.The two groups were treated 5 days a week,twice a day,45 minutes each for 2 weeks.The M.D.Anderson Dysphagia Inventory(MDADI),maximum phonation time(MPT),and Standardized Swallowing Assessment(SSA),flexible endoscopic examination of swallowing(FEES)combined with modified invasion and aspiration score(MPAS score)and overall clinical efficacy before and after treatment were compoued between the two groups.Results After 2 weeks of treatment,the swallowing function of both groups improved,but the MDADI scores in the observation group were better than those of in the control group in all cate-gories(P＜0.001),MPT(7.19±1.31)was better than that of the control group(4.29±0.88)(=9.436,P＜0.001),SSA(19.25±1.12)was better than that of the control group(21.20±2.55)(=-2.894,P＜0.05),and FEES combined with MPAS score(1.75±0.85)was better than the control group(2.70±1.34)(=-2.674,P＜0.001),and the overall clinical efficacy(18,90.00％)was better than the control group(12,60.00％)(Z=-3.894,P＜0.001).Conclusion Early application of active breathing and circulation technique combined with swallowing training can improve the swallowing function of patients to a greater extent and reduce the incidence of aspiration compared with swallowing function training alone.

Objective:To summarize and analyze clinical characteristics of pediatric mandibular condylar fractures and the long-term therapeutic effects of closed treatment.Methods:A retrospective study was conducted for pediatric condylar fracture in the Department of Oral and Maxillofacial Surgery of Peking University School and Hospital of Stomatology from October 2015 to October 2019, including 33 males (67.3%) and 16 females (32.7%), with an average age of (8.3±2.1) years old. According to the treatment methods, the children were divided into two groups: group A was a removable occlusal splint accompanied with functional exercise, group B was a pure functional exercise. Forty-nine cases (76 sides) children with intracapsular condylar fracture were included in this study. Twenty-three cases in group A and 26 cases in group B. The maximum month opening increased from (20.0±6.2) mm to (46.0±5.3) mm 6 months after closed treatment. Subjective evaluation, special examination, qualitative analysis and quantitative analysis of imaging were used to evaluate the condylar remodeling and functional recovery of temporomandibular joint in two groups of children after closed treatment of intracapsular condyle fracture.Results:There was no significant difference in subjective evaluation, maximum opening examination, mouth open-type, mandibular protrusion, lateral movement and qualitative analysis of imaging at the six-month follow-up after injury. Quantitative imaging measurements showed that the condylar anteroposterior diameter and condylar height in Group B were significantly higher than those in Group A after 1 year of injury.Conclusions:Closed treatment for pediatric condylar fractures can achieve satisfactory results. After 6 months of injury, the children in the two groups could recover the temporomandibular joint function and promote the condylar adaptative remodeling.

Objective:To investigate the effect of astragaloside A (AS-A) on the photoreceptor degeneration induced by sodium iodate (NaIO 3) and its related mechanism. Methods:Sixty healthy male C57BL/6J mice, aged 6-8 weeks, were randomly divided into normal control (NC) group, NaIO 3 group, and ASA group, with twenty mice in each group. 30 min before modeling, AS-A group mice were intraperitoneally injected with 100 μl AS-A at a dose of 100 mg/kg body weight. 30 min later, mice in NaIO 3 group and AS-A group were intraperitoneally injected with 100 μl NaIO 3 at a dose of 30 mg/kg body weight. Subsequently, AS-A group mice were administered AS-A twice daily at 12 h intervals until the end of the experiment. On day 1 post-modeling, zonula occludens-1 (ZO-1) immunohistochemistry was performed to observe the structure of retinal pigment epithelium (RPE) cells; real-time quantitative polymerase chain reaction (qPCR) was conducted to detect the mRNA expression of various retinal chemokine ligand-2 ( Ccl2), interleukin-1 beta ( Il-1β), mixed lineage kinase domain-like protein ( Mlkl), receptor-interacting protein kinase 3 ( Ripk3), and tumor necrosis factor ( Tnf). On day 3 post-modeling, immunohistochemistry was performed to observe the expression of ionized calcium binding adaptor molecule 1 (Iba1) and glial fibrillary acid protein (GFAP) in the retina; TdT-mediated dUTP nick-end labeling (TUNEL) assay was used to detect photoreceptor cell death in each group. On day 4 post-modeling, fundus morphology of mice in each group was observed by fundus color photography and optical coherence tomography (OCT). Hematoxylin-eosin staining (HE) was used to observe the morphological structure of the retina in each group. Inter-group comparisons between two groups were conducted using independent samples t-test, while comparisons among three groups were performed using one-way ANOVA. Results:Fundus color photography and OCT examination showed that a large number of scattered yellow-white subretinal nodular structures in the fundus of NaIO 3 group mice, and a large number of strong reflection areas in the RPE layer. The number of strong reflection areas in the RPE layer was reduced in the AS-A group. Immunohistochemical analysis of ZO-1 showed that ZO-1 was largely lost on the RPE cell membrane in that NaIO 3 group; whereas in the AS-A group, ZO-1 was evenly distributed on the RPE cell membrane. HE staining results showed circular black deposits were visible in the RPE layer of the NaIO 3 group, and the inner and outer segments of photoreceptors were severely damaged, with a significant decrease in the number of outer nuclear layer (ONL) cell nuclei; whereas in the AS-A group, the RPE layer pigments were orderly, the inner and outer segments of photoreceptors were intact, and the number of ONL cell nuclei significantly increased. The results of TUNEL staining show that numerous TUNEL-positive cell nuclei were observed in the ONL of the retina in the NaIO 3 group, while the number of TUNEL-positive cell nuclei in the ONL of the retina was significantly reduced in the AS-A group, with statistically significant differences ( t=2.66, P<0.05). The analysis of qPCR data showed that compared with the AS-A group, the relative expression levels of Mlkl, Ripk3, Ccl2, Il-1β and Tnf mRNA in the retina were significantly increased in the NaIO 3 group, with statistically significant differences ( F=39.18, 10.66, 53.51, 41.40, 24.13; P<0.001). Immunohistochemical staining results showed that compared with NC group and AS-A group, the positive expression of GFAP in retina of NaIO 3 group was significantly increased, and the difference was statistically significant ( F=9.62, P<0.05). Conclusion:AS-A antagonizes NaIO 3-induced photoreceptor degeneration in part by inhibiting photoreceptor cell death and neuroinflammation. Meanwhile, AS-A treatment protects against NaIO 3-triggered perturbation of retinal homeostasis.
