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.

The major components of Olaflur raw material were characterized using ultra performance liquid chromatography-quadrupole time-of-flight-mass spectrometry(UPLC-Q-TOF/MS).The results revealed that cetyl amine fluoride(C16-AmF),octadecene amine fluoride(C18:1-AmF),and octadecyl amine fluoride(Olaflur)were the main components.The contents of C16-AmF,C18:1-AmF,and Olaflur in oral care products were determined via ultra performance liquid chromatography-charged aerosol detector coupled with solid-phase extraction(SPE-UPLC-CAD).The oral care sample was dispersed evenly with a 50%ethanol aqueous solution,and then vortexed with ethanol.The supernatant was collected by centrifugation,concentrated to near dryness,and redissolved with ultrapure water.The re-dissolved sample was loaded onto a Poly-Sery HLB Pro SPE column for purification and elution.The acetonitrile eluate was collected and concentrated to 1.0 mL.Finally,a prepared test solution was separated on a Thermo Acclaim Surfactant Plus chromatographic column(2.1 mm×150 mm,3 μm).Acetonitrile and 100 mmol/L acetic acid-ammonium acetate aqueous solution(pH=4.8)were used as the mobile phases for gradient elution.The flow rate was 0.3 mL/min and cloumn temperature was maintained at 40℃.The sample was detected using a charged aerosol detector,and quantified using an external standard method.The experimental results indicated that the three organic fluorinated amines showed good linear relationship in their respective concentration ranges.The correlation coefficients(r)were greater than 0.99.The limit of detection(LOD)and the limit of quantification(LOQ)of C16-AmF were 2.0 and 8.0 μg/mL,respectively.The LOD and LOQ of C18:1-AmF were 2.0 and 8.0 μg/mL,respectively.The LOD and LOQ of Olaflur were 3.0 μg/mL and 10.0 μg/mL,respectively.The spiked recoveries of the three organic fluorinated amines were 84.3%-104.2%,with relative standard deviations(RSDs)of 4.93%-5.82%.The 28 batches of commercial oral care samples were detected by this method and the results indicated that three organic fluorinated amines were detected in 18 samples and the total content were 22.2-11477.8 μg/g.This method had high sensitivity and good reproducibility.It was suitable for verifying the authenticity of the claims of oral care products promoted with Olaflur as the main efficacy ingredient and selling point,and provided a valuable reference for establishing and improving the standard analytical method for Olaflur.

OBJECTIVE To explore the value of healthcare failure mode and effect analysis mode(HFMEA)com-bined with enhanced management of link quality in centralized processing of rigid endoscopic instruments.METHODS Totally 80 pieces of rigid endoscopic instruments that were recycled by the endoscopy room of otolar-yngology department of The First Medical Center of PLA General Hospital from Jan.2022 to Dec.2022 were as-signed as the control group,and 70 pieces of rigid endoscopic instruments that were recycled under the HFMEA model combined with enhanced management of link quality from Jan.2023 to Dec.2023 were assigned as the ex-perimental group.The effect of the management and the qualified rate of instruments were compared between the two groups of instruments,compare the satisfaction under the different intervention modes.RESULTS The scores of instrument disassembly and assembly,cleaning procedures,cleaning quality,environmental management and packaging quality were higher in the experimental group than in the control group(P＜0.05).The unqualified rate of instruments of the experimental group was 10.00％,lower than 23.75％of the control group(x2=4.926,P=0.026).The staff's satisfaction with the work of the experimental group was 91.67％,higher than 66.67％of the control group(Z=2.026,P=0.043).CONCLUSION For the centralized management of rigid endoscopic in-struments,the implementation of the enhanced management of link quality under the HFMEA mode can effective-ly improve the effect of management of the instruments and reduce the unqualified rate of recycled instruments,demonstrating a positive effect on raising the staff's satisfaction with the recycle process of instruments.

Aim To investigate the effect of chrysoeriol on pulmonary vascular remodeling in pulmonary hyper-tension by animal experiments combined with cell ex-periments,and to explore its potential therapeutic tar-gets by network pharmacology.Methods The target of chrysoeriol was collected in Targetnet,SEA and SwissTargetPrediction database.Pulmonary arterial hy-pertension(PAH)targets were collected in the Dis-GeNET and GeneCards databases,and PPI network map was drawn in the STRING database,and key tar-gets were screened.The GO and KEGG pathway en-richment analysis was carried out through DAVID data-base and Weishengxing platform.AutoDock software was used for molecular docking of key core targets.The PAH model of rats was constructed,and the pulmo-nary hemodynamics and vascular remodeling were de-tected by echocardiography,HE and Masson staining.Primary pulmonary smooth muscle cells were extracted,and the effects of drugs on pathway proteins were de-tected in vitro.Results The results of network phar-macology showed that chrysoeriol exerted therapeutic effects on pulmonary hypertension by affecting key tar-gets such as AKT1,SRC,EGFR,MMP9 and gsk3 β,and signaling pathways such as EGFR and PI3K-AKT.Molecular docking showed that chrysoeriol had good binding ability with 5 key target genes.Animal experi-ments showed that the pulmonary hemodynamic func-tion of PAH rats was significantly improved after ad-ministration of chrysoeriol.The remodeling of small pulmonary arteries was significantly reduced.Cell ex-periments showed that chrysoeriol could inhibit the ex-pression of proliferation,migration and phenotypic transformation genes.Conclusion Chrysoeriol may play a role in the treatment of pulmonary hypertension through multiple targets.

OBJECTIVE: To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality. METHODS: A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters. RESULTS: The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights. CONCLUSION Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

Objective:To summary the clinical and electrophysiological characteristics of temporal lobe epilepsy (TLE) originating from the temporal pole (TP), and to conduct brain network analysis based on stereo-electroencephalogram (SEEG) and head positron emission tomography- computed tomography (PET-CT).Methods:A retrospective analysis was conducted on patients with TLE who underwent SEEG implantation from January 1, 2019 to September 1, 2023 in Guangdong Sanjiu Brain Hospital. Based on anatomical-electrical-clinical analysis and SEEG findings, patients with seizures originating from the TP were selected. The clinical data, head magnetic resonance imaging (MRI), PET-CT, scalp electroencephalogram were reviewed, and the seizure-induced network was analyzed based on SEEG and head PET-CT.Results:A total of 108 cases of TLE were analyzed, of whom 13 cases had an epileptogenic zone located at the TP, accounting for 12% (13/108) of all TLE patients. Among them, 8 were males and 5 were females, and age of onset was (11.6±7.8) years. All of them were drug-resistant epilepsy patients, of whom 6 cases had normal cognitive function, 4 had mild cognitive abnormalities, and 3 had severe cognitive decline. A total of 59 seizures were recorded, and the occurrence rate of generalized tonic-clonic seizures (GTCS) was 42% (25/59). Seizure symptoms were classified into 3 types: the first type was hypermotor, seen in 9 patients; the second type was complex motor, seen in 2 patients; and the third type was automotor, seen in 2 patients. Head MRI showed that 9 cases had a blurring of the TP on one side, with or without hippocampal sclerosis; 2 cases had a mass at the TP without hippocampal sclerosis; 2 cases were negative on head MRI. Head PET-CT showed that 13 cases had TP hypometabolism on the lesion side, of whom 11 cases had hypometabolism involving the medial temporal lobe (mTL), posterior orbital gyrus (POG), anterior cingulate gyrus (ACG) and insular lobe at the same time, the other 2 cases combined with ipsilateral hypometabolism of the medial temporal lobe. Pathology showed that 7 cases had microcortical dysplasia of the TP; 3 had focal cortical dysplasia Ⅰ or focal cortical dysplasia Ⅱ; 2 had benign tumors. Scalp electroencephalogram showed that interictal phase was divided into 3 discharge patterns: bilateral temporal regions with prominent lesion side; bilateral anterior regions with prominent lesion side; lesion-side hemisphere with prominent temporal region. Ictal period showed 4 initial patterns: lesion-side hemispheric rhythmic spikes-slow waves or polyspikes-slow waves; lesion-side anterior region rhythmic slow waves; lesion-side anterior region low voltage fast (LVF) activities, and diffuse LVF with prominent lesion-side hemisphere. SEEG showed that 13 patients received electrode implantation with (9±2) electrodes per patient, divided into 3 seizure patterns: type 1: TP?adjacent temporal neocortex?POG, ACG and insula?mTL; type 2: TP?para hippocampal gyrus and the base of temporal lobe?ACG ,POG and insula?mTL; type 3: TP?mTL?insular lobe?POG.Conclusions:TLE originating from the TP is relatively rare, with hypermotor or complex motor as the main manifestations, and automotor being relatively less common, which is more likely to be followed by GTCS. The epileptogenic network analysis displays a tendency to spread from the TP to the frontal and insular lobes, as well as to the mTL, with the former pattern being more common. Common etiologies are cortical dysplasia and benign tumors of the TP without hippocampal sclerosis.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
