Objective The effect of intra-aortic balloon counterpulsation combined with recombinant human brain natriuretic peptide(rhBNP)treatment on ventricular remodeling after percutaneous coronary intervention(PCI)in elderly patients with acute anterior wall myocardial infarction.Methods A retrospective analysis was con-ducted on 66 elderly patients with acute anterior myocardial infarction who underwent emergency PCI in our hospital from January 2018 to June 2023.They were divided into a control group(n=32)who underwent PCI+rhBNP,and a study group(n=32)who underwent PCI+rhBNP+intra-aortic balloon counterpulsation.Blood pressure,lactic acid level,mechanical complications,ventricular remodeling,inflammatory factors,myocardial enzymology,ox-LDL level were detected and compared between the two groups.Results Before treatment,Lactic acid,diastolic blood pressure,systolic blood pressure,left ventricular end-systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD),left ventricular posterior wall thickness(LVPWT),left ventricular remodeling index(LVRI),left ventricular ejection fraction(LVEF),homocysteine(Hcy),interleukin-6(IL-6)and myocardial troponin were compared between the two groups.Myocardial troponin T(cTnT),lactate dehydrogenase(LDH),creatine kinase isoenzyme(CK-MB),oxidized low density lipoprotein(ox-LDL)levels(P>0.05);At 3 months follow-up after discharge,the levels of lactic acid,LVESD,LVEDD,LVPWT,LVRI,Hcy,IL-6,cTnT,LDH,CK-MB and ox-LDL were decreased,and the levels were lower in the study group,and the levels of diastolic blood pressure,systolic blood pressure and LVEF were increased,and the levels were higher in the study group(P<0.05).The pro-portion of mechanical complications between the two groups before and after treatment were compared(P>0.05).Conclusion In elderly patients with acute anterior myocardial infarction after emergency PCI,intra-aortic balloon counterpulsation combined with rhBNP could alleviate ventricular remodeling,myocardial injury,reduce inflamma-tory injury,improve oxidative stress response,and regulate tissue perfusion.

Objective:To evaluate the potential value of gut microbiota metabolites in predicting the efficacy of neoadjuvant chemoradiotherapy combined with immunotherapy in patients with locally advanced rectal cancer.Methods:Prospectively collected case data from 32 patients with locally advanced rectal patients, who underwent total mesorectal excision at Beijing Friendship Hospital, Capital Medical University, between October 2021 and August 2022. Among these patients, 18 (56.25%) were male and 14 (43.75%) were female, with ages ranging from 37 to 79 years and a mean age of (61.69±8.73) years. Postoperative pathological response was evaluated using the Tumor Regression Grade (TRG), dividing the patients into two groups: an efficacious group (ypT 0N 0, n=14) and a non-efficacious group (non-ypT 0N 0, n=18). Stools from 14 patients in the efficacious group and 18 patients in the non-efficacious group, who had experienced neoadjuvant chemoradiotherapy combined with immunotherapy, were collected before treatment. Metabolites were analyzed using high-performance liquid chromatography-tandem mass spectrometry, and pathway enrichment analysis was performed. A random forest model was constructed based on the differential metabolites. The data were analyzed by using R4.1.1 and 26.0 software. Results:Through untargeted metabolomics analysis, 2′-Deoxyinosine and albiflorin were enriched in the responders, while Sorbitan monooleate, 2-(Formylamino) Benzoic Acid, and 12-Hydroxydodecanoic acid were enriched in the non-responders ( P<0.05); Arachidonic acid metabolism and tryptophan metabolism were enriched, and the AUC for the model was 0.976. Conclusions:Rectal cancer patients with or without complete postoperative pathological remission exhibit differences in the metabolites of their intestinal microbiome prior to undergoing neoadjuvant chemoradiotherapy combined with immunotherapy. The identified differential metabolites have the potential to serve as predictive biomarkers for treatment efficacy.

Genome-wide association studies (GWASs) are the most widely used method to identify genetic risk loci associated with orofacial clefts (OFC). However, despite the increasing size of cohort, GWASs are still insufficient to detect all the heritability, suggesting there are more associations under the current stringent statistical threshold. In this study, we obtained an integrated epigenomic dataset based on the chromatin conformation of a human oral epithelial cell line (HIOEC) using RNA-seq, ATAC-seq, H3K27ac ChIP-seq, and DLO Hi-C. Presumably, this epigenomic dataset could reveal the missing functional variants located in the oral epithelial cell active enhancers/promoters along with their risk target genes, despite relatively less-stringent statistical association with OFC. Taken a non-syndromic cleft palate only (NSCPO) GWAS data of the Chinese Han population as an example, 3664 SNPs that cannot reach the strict significance threshold were subjected to this functional identification pipeline. In total, 254 potential risk SNPs residing in active cis-regulatory elements interacting with 1 718 promoters of oral epithelium-expressed genes were screened. Gapped k-mer machine learning based on enhancers interacting with epithelium-expressed genes along with in vivo and in vitro reporter assays were employed as functional validation. Among all the potential SNPs, we chose and confirmed that the risk alleles of rs560789 and rs174570 reduced the epithelial-specific enhancer activity by preventing the binding of transcription factors related to epithelial development. In summary, we established chromatin conformation datasets of human oral epithelial cells and provided a framework for testing and understanding how regulatory variants impart risk for clefts.

Cardiac arrhythmia is one of the most common cardiovascular diseases,with high morbidity and mortality,which threatens human health and lives. With the development of medicine, natural products are revealing ever-greater anti-arrhythmic benefits and potential. However,their targets have not been fully clarified. In the recent ten years ,scientists have been studying the molecular mechanisms of natural products that have been found to inhibit INa,ICa-L,Ito,IK1,IKr,IKM3,HERG channel current and steady state K+ current,promote IKs and IKATP,inhibit microRNA-1 expression and change cardiac microRNA expression profile,affect Na+-K+-ATPase and superoxide dismutase activity,inhibitβ receptor and angiotensinⅡ receptor,and regulate lipid metabolism,thus affecting cardiac rhythm and exerting anti-arrhythmic effect. This paper revies the research advances in the antiarrhythmic tar?gets of natural products.

OBJECTIVE An understanding of the complex anatomy of the anterior skull base is crucial for the surgeon doing endoscopic surgery. The anatomic data of the olfactory sulcus and adjacent structures in Chinese patients were defined using 3-dimensional reconstruction images. The surgeon is encouraged to develop a detailed pre-operative surgical plan by utilizing these dynamic anatomical observations to avoid intracranial injury. METHODS The paranasal sinus CT scanning images of 100 adults were reconstructed for observation using EBW2.0 software and multiplanar reformation. All data obtained were in the coronal plane from the anterior point of the olfactory sulcus. The cribriform plate depth as compared to the ethmoid roof and adjacent structures, was measured bilaterally. Data obtained on adjacent structures include the vertical height of the lateral lamella of olfactory sulcus, the horizontal distance between the cribriform plate and the orbital lamella, the length of the middle turbinate, the height of the orbit, and the vertical distance between the cribriform plate and the nasal floor. RESULTS The olfactory sulcus was classified into three types: platform type (60 %), sloping type (17 %) and mixed type(23 %), as distinguished from Keros classification. In this study the vertical height of the lateral lamella of olfactory sulcus was (5.03 ± 0.17) mm (R) and (5.39 ± 0.19) mm (L) in platform type, and (2.79 ± 0.49) mm (R) and (4.72 ± 0.49) mm (L) in the mixed type. There were statistically significant differences between the right side and the left side in these two types (P＜0.01). The horizontal distance between the cribriform plate and the orbital lamella on the same side was significantly different between the platform type and the mixed type of olfactory sulcus. A similar result was observed for the vertical distance between the cribriform plate and the nasal floor. Gender differences exist in the horizontal distance between the cribriform plate and orbital lamella on the same side and the vertical distance between the cribriform plate and the nasal floor. CONCLUSION Different types of olfactory sulcus have distinct characteristics, hence care which must be taken into account when doing endoscopic surgery.
