Coronary atherosclerotic heart disease is a major cardiovascular condition driven by atherosclerosis, distinguished by chronic inflammation and dysregulated lipid metabolism. The gut microbiota plays an essential role in human health and disease, with research indicating a strong association between gut microbial metabolism and the development and progression of coronary heart disease. This article provides a review of the relationship between gut microbiota and coronary heart disease, as well as the mechanisms by which traditional Chinese medicine regulates digestive tract microbiota to treat coronary heart disease, which systematically explains how the gut microbiota, through metabolic products and immune regulation, contributes to the occurrence and progression of coronary heart disease, and summarizes recent advances in research on traditional Chinese medicine's regulation of gut microbiota for treating coronary heart disease. It aims to provide further reference and insights for exploring the relationship between gut microbiota and coronary heart disease, as well as traditional Chinese medicine approaches for treating coronary heart disease.

Objectives:This study aims to explore the clinical significance of lateral pelvic sentinel lymph node biopsy (SLNB) using indocyanine green (ICG) fluorescence navigation in laparoscopic lateral pelvic lymph node dissection (LLND) and evaluate the accuracy and feasibility of this technique to predict the status of lateral pelvic lymph nodes (LPLNs).Methods:The clinical and pathological characteristics, surgical outcomes, lymph node findings and perioperative complications of 16 rectal cancer patients who underwent SLNB using ICG fluorescence navigation in laparoscopic LLND in the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College during April 2017 and October 2022 were retrospectively collected and analyzed. The patients did not receive preoperative neoadjuvant radiotherapy and presented with LPLNs but without LPLN enlargement (MRI showed the maximum short axes of the LPLNs were ≥5 mm and <10 mm at first visit).Results:All 16 patients were successfully performed SLNB using ICG fluorescence navigation in laparoscopic LLND. Three patients underwent bilateral LLND and 13 patients underwent unilateral LLND. The lateral pelvic sentinel lymph nodes (SLNs) were clearly fluorescent before dissection in 14 patients and the detection rate of SLNs for these patients was 87.5%. Lateral pelvic SLN metastasis was diagnosed in 2 patients and negative results were found in 12 patients by frozen pathological examinations. Among the 14 patients in whom lateral pelvic SLNs were detected, the dissected lateral pelvic non-SLNs were all negative. All dissected LPLNs were negative in two patients without fluorescent lateral pelvic SLNs. The specificity, sensitivity, negative predictive value, and accuracy was 85.7%, 100%, 100%, and 100%, respectively.Conclusions:This study indicates that lateral pelvic SLNB using ICG fluorescence navigation shows promise as a safe and feasible procedure with good accuracy. This technique may replace preventive LLND for locally advanced lower rectal cancer.

Objective To explore the mechanism of tumor-associated fibroblasts(CAFs)for regulating proliferation and migration of prostate cancer(PCa)cells.Methods We conducted a bioinformatics analysis to identify miRNAs with high expression in PCa.The proliferation,migration and hsa-miR-18b-5p expression levels were observed in PCa cells co-cultured with CAFs.We further examined hsa-miR-18b-5p expression level in 20 pairs of PCa and adjacent tissue samples and in different PCa cell lines and normal epithelial cells using RT-qPCR.In PCa cell lines C4-2 and LNCAPNC,the effects of transfection with a hsa-miR-18b-5p inhibitor on cell proliferation,migration,invasion,drug resistance,apoptosis and cell cycle were evaluated,and the effects of has-miR-18b-5p knockdown on C4-2 cell xenograft growth and mouse survival were observed in nude mice.Dual luciferase reporter gene assay was used to validate the targeting relationship between hsa-miR-18b-5p and its target genes,whose expressions were detected in PCa cells using RT-qPCR and Western blotting.Results The expression of hsa-miR-18b-5p was significantly increased in the co-culture of CAFs and PCa cell lines,which exhibited significantly enhanced proliferation and migration abilities.Transfection with has-miR-18b-5p inhibitor strongly attenuated the effect of CAFs for promoting proliferation and migration of PCa cells,and in C4-2 and LNCAP cells cultured alone,inhibition of hsa-miR-18b-5p obviously suppressed cell proliferation,migration,invasion,and drug resistance.In the tumor-bearing mice,hsa-miR-18b-5p knockdown in the transplanted cells significantly inhibited xenograft growth and increased the survival time of the mice.Target gene prediction suggested that FBXL3 was a potential target of hsa-miR-18b-5p,and dual luciferase reporter gene confirmed a binding site between them.In C4-2 and LNCAP cells,hsa-miR-18b-5p knockdown resulted in significantly increased expression levels of FBXL3.Conclusion CAFs promotes proliferation and migration of PCa cells by up-regulating hsa-miR-18b-5p to suppress FBXL3 expression.

Objective:To understand the status quo of emotional intelligence, emotional labor, and humanistic caring ability of medical staff, and to clarify their internal relationship.Methods:Convenience sampling was used to select 713 medical staff from a grade A tertiary hospital in Chengdu, Sichuan Province, China. Emotional Intelligence Scale, Humanistic Caring Scale, and Emotional Labor Scale were used to measure the emotional intelligence, humanistic caring ability, and emotional labor of medical staff. SPSS 22.0 software was used to establish a database for statistical description and analysis. Process 3.2 software was used to analyze the mediating effect.Results:In humanistic caring ability, the average score of comprehension dimension was the highest (75.62±8.20) and the average score of patience dimension was the lowest (58.53±5.01). In emotional labor, the average score of the deep action dimension was the highest (23.39±3.85) and the average score of the surface action dimension was the lowest (17.73±3.18). In emotional intelligence, the average score of self-emotion evaluation dimension was the highest (21.76±3.30) and the average score of other-emotion evaluation dimension was the lowest (20.07±3.71). Positive correlations were found between humanistic caring ability and emotional intelligence, between humanistic caring ability and emotional labor, and between emotional intelligence and emotional labor ( P<0.01). Humanistic caring ability had a partial mediating effect between emotional intelligence and emotional labor. Humanistic caring ability had direct and indirect effects on emotional labor, and the effect sizes were 0.279 and 0.029, respectively. Conclusion:Emotional intelligence has a direct positive predictive effect on emotional labor, humanistic caring ability as an intermediary variable indirectly and positively predicts emotional labor. Humanistic caring ability plays a partial mediating role between emotional intelligence and emotional labor. Attention should be paid to the emotional labor of medical staff, and the emotional labor of medical staff should be improved through targeted training on emotional intelligence and humanistic caring ability. These efforts will improve the current situation and establish a harmonious doctor-patient relationship.

Objective:To investigate the pharmacokinetics of sugammadex in reversal of rocuronium-induced muscle relaxant residual in infants and young children undergoing daytime surgery.Methods:One hundred and four pediatric patients of either sex, aged 3-36 months, of American Society of Anesthesiologists Physical Status classification Ⅱ, with body mass index of 18.5-28.0 kg/m 2, diagnosed with oblique inguinal hernia and/or hydrocele, scheduled for laparoscopic high ligation of hernia sac and/or high ligation of sphingoid surgery, were included in the study. Intraoperative neuromuscle relaxation was assessed by transdermal stimulation of the ulnar nerve in the wrist using a TOF Guard monitor. Rocuronium 0.9 mg/kg, propofol 3 mg/kg, and sufentanyl 0.5 μg/kg were intravenously injected for anesthesia induction, and propofol 6-8 mg·kg -1·h -1 was intravenously infused to maintain anesthesia. The pediatric patients were divided into Ⅰgroup and Ⅱ group according to the degree of postoperative neuromuscular block. In group Ⅰ, sugammadex 2 mg/kg was intravenously injected when TOF returned to T 2 recurrence. In group Ⅱ, sugammadex 4 mg/kg was intravenously injected when the single stimulation count was 1 or 2 after tetanic stimulation. At 2 and 10 min after rocuronium administration, at the end of operation, 2 and 10 min after sugammadex administration, and when the children met the standard of leaving the resuscitation room, venous blood samples were collected for determination of plasma concentrations of rocuronium and sugammadex using ultra-high performance liquid chromatography-mass spectrometry. Pharmacokinetic parameters were determined using the Pheonix WinNonlin software. The onset of rocuronium and time for recovery of TOF ratio to 90% were recorded. Results:The pharmacokinetics of sugammadex was fitted to the nonlinear mixed-effect satrioventricular model.There was no significant difference in the peak concentration, area under the drug concentration-time curve, elimination half-life, apparent clearance, apparent volume of distribution, mean retention time, and time for TOF ratio returning to 90% between the two groups ( P> 0.05). Conclusions:The pharmacokinetics of sugammadex in reversal of rocuronium-induced muscle relaxant residual is fitted to a nonlinear mixed-effect satrioventricular model, and sugammadex 2 and 4 mg/kg have similar pharmacokinetics in infants and young children undergoing daytime surgery.

In colorectal cancer surgery, loop ileostomy is sometimes necessary to prevent anastomotic leakage. Although ileostomy reversal is relatively simple, postoperative complication is inevitable. In recent years, laparoscopic surgery has been gradually applied in ileostomy reversal due to its small trauma, fast recovery, and low complications, exhibiting satisfactory short-term outcomes. This review analyzes the application of the laparoscopic technique in ileostomy surgery and explores the potential of total laparoscopic surgery, aiming to provide a new perspective for the clinical application of laparoscopic ileostomy reversal.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Aim To investigate the role of mechano- sensitive ion channel Piezol in regulating electrical re-modeling of atrial myocytes induced by hypertension and to further explore the potential mechanisms.Methods Spontaneously hypertensive rats ( SHR ) aged 30 - 32 weeks treated with or without valsartan (30 mg • kg 1 • d 1 ) were used.Wistar rats were used as control.Western blot was used to detect the protein expression of Piezol , Src and Cavl.2 in atrial appendages of rats and in atrial myocytes ( HL-1 cells) exposed to different levels of high hydrostatic pressure (20 and 40 mmHg) , Piezol inhibitor (GsmTx4) and agonist ( Yodal ) in vitro.Whole-cell patch clamp technique was employed to detect L-tvpe calcium current (ICa, ) and action potential duration ( APD) of atrial myocytes.Results Compared with Wistar rats in control group, the protein expressions of Piezol and Src significantly increased and the expression of Cavl.2 decreased in SHR group (P < 0.05 ), while the a- bove changes could he reversed in SHR treated with valsartan( P < 0.05 ) .Meanwhile, higher hydrostatic pressure (40 mniHg) could increase the expressions of Piezol and Src in HL-1 cells( P <0.05) and decrease the protein expression of Cavl.2 (P <0.05 ) , accompanied by a shortened APD and a decreased ICa,.GsmTx4 could significantly reverse the above changes.In addition, Piezol agonist Yodal could simulate electrical remodeling and related signal molecule changes in atrial myocytes induced by the high hydrostatic pressure.Conclusions Mechanosensitive ion channel Piezol participates in electrical remodeling induced by hypertension via activating Src kinase signaling pathway and then leading to the decrease of ICa ,.
