Objective To analyze the characteristics and causes of an occupational acute carbon monoxide poisoning incident caused by a nitrogen generator malfunction. Methods The workers and the workshop from an electronic component manufacturing company in Guangzhou City, which had an occupational acute carbon monoxide poisoning incident, were selected as the research subjects using the retrospective investigation method. Relevant data of worksite survey of occupational health, clinical records of poisoning patients, and occupational disease diagnosis data were collected for analysis. Results A total of 15 workers who experienced discomfort in this incident, were from the final inspection workshop using high-purity nitrogen (purity of 99.999%). The short-term exposure concentration of carbon monoxide in the workplace air at three oven operating posts using high-purity nitrogen was 64.1, 581.0, and 142.0 mg/m³, respectively, while the concentration in the workplace air at the oven operating posts using regular nitrogen and the nitrogen-generating room was <0.1 mg/m³. Carboxyhemoglobin saturation levels in the 15 patients ranged from 2.000%-17.300%. Occupational acute mild carbon monoxide poisoning was diagnosed in nine patients, occupational acute carbon monoxide exposure reactions was diagnosed in six patients. This poisoning incident was caused by machine malfunction and improper operation, leading to occupational acute carbon monoxide poisoning. Conclusion Companies using nitrogen production machine should enhance their ability to identify carbon monoxide risks, strengthen training and management of workers, establish emergency response plans for nitrogen production and use, ensure proper maintenance of production equipment, and optimize operational procedures to prevent acute poisoning incidents.

Objective To evaluate the efficacy and safety of intense pulsed light(IPL)combined with micro-crosslinked hyaluronic acid injected by Shuiguang needle in skin photoaging.Methods Patients with skin photoaging who were treated in Hangzhou Plastic Surgery Hospital from January 2021 to February 2023 were selected.According to the different treatment methods,they were divided into 3 groups:one group was treated with micro-crosslinked hyaluronic acid injected by Shuiguang needle(Shuiguang treatment group),one group was treated with IPL alone[broad band light(BBL)treatment group],and one group was treated with IPL combined with micro-crosslinked hyaluronic acid injected by Shuiguang needle(combined treatment group).The patients were followed up 3 months after treatment.Global scores for photoaging(GSP)were used to evaluate the photoaging degree on the whole face.Global aesthetic improvement scale(GAIS)was used to evaluate the improvement of the overall appearance after treatment.The data of facial wrinkles,texture,pores,brown spots and red areas of patients was collect by using VISIA complexion analysis system.The visual analog scale(VAS)wasused for pain assessment,and adverse effects were recorded.Results GSP score of combined treatment group was lower than that of Shuiguang treatment group and BBL treatment group(P＜0.05).GAIS improvement scores for wrinkles and texture in combined treatment group were higher than those of Shuiguang treatment group and BBL treatment group(P＜0.05),and the GAIS improvement score for pores in combined treatment group was higher than that in BBL treatment group(P＜0.05).The analysis results of VISIA skin test showed that the values of wrinkles and brown spots in combined treatment group after the operation were lower than those in Shuiguang treatment group and BBL treatment group(P＜0.05),and the value of the red area in combined treatment group was lower than that in Shuiguang treatment group(P＜0.05).The effective rates of wrinkle,texture and pore in combined treatment group was 88.2％,94.1％and 94.1％,respectively,higher than those in other two groups.The complications were immediate erythema,acupuncture reaction,and papule,which could be relieved within a few hours.Conclusion IPL combined with micro-crosslinked hyaluronic acid injection in skin photoaging appears to be effective,durable and safety for skin photoaging.

Objective To investigate the predictive value of changes in various indicators of routine blood tests for the severity of brain damage in patients with acute cerebral hemorrhage(ACH)in high-altitude regions.Methods A retrospective analysis was conducted using data from 249 inpatients diagnosed with ACH at a hospital in Xizang.Patient data,including demographic information and results of routine blood tests,were collected.Based on their Glasgow Coma Scale(GCS)scores,the patients were divided into 2 groups,a mild brain damage group(GCS≥13 points)and a moderate-to-severe brain damage group(GCS≤12 points).Demographic information and laboratory test results were compared between the two groups.Binary logistic regression analysis was performed to examine the relationship between indicators of routine blood tests and the severity of brain damage,and key indicators were identified.The receiver operating characteristic(ROC)curve analysis was used to evaluate the predictive performance of key indicators in various combinations for the severity of brain injury in ACH patients.Results The moderate-to-severe group had a higher proportion of high-altitude residents,as well as elevated levels of white blood cells(WBC),neutrophils(N),neutrophil-to-lymphocyte ratio(NLR),systemic inflammatory index(SII),neutrophil-to-platelet ratio(NPR),and C-reactive protein(CRP)-to-lymphocyte ratio(CLR),compared to the mild group.On the other hand,the levels of lymphocytes(L),platelets(PLT),and platelet-to-albumin ratio(PAR)in the moderate-to-severe group were lower than those in the mild group.Binary logistic regression analysis showed that WBC(OR=1.221,95%CI:1.127-1.322),CRP(OR=1.019,95%CI:1.004-1.033),CRP-to-albumin ratio(CAR)(OR=1.845,95%CI:1.137-2.996),and CLR(OR=1.018,95%CI:1.005-1.030)were positively associated with moderate-to-severe brain damage,and that their elevated levels were associated with an increase in risk by the corresponding folds.PAR(OR=0.845,95%CI:0.721-0.990)was negatively correlated with moderate-to-severe brain damage,with an increase resulting in a reduction of risk by 0.845 times.ROC curve analysis showed that,in the mild group,the combined AUC for WBC+CRP was 0.689(optimal cutoff value 0.19,specificity 0.776,95%CI:0.624-0.755);the PAR+CAR+CLR combination(CAR was not significant,P>0.05)had an AUC of 0.675(optimal cutoff value 0.19,specificity 0.760,95%CI:0.609-0.741);the key indicator combination of WBC+PAR+CLR(CRP was not significant,P>0.05)demonstrating the strong predictive performance moderate-to-severe brain damage,yielding an AUC of 0.737(optimal cutoff value 0.08,specificity 0.624,95%CI:0.676-0.798).Conclusion The indicator combinations of WBC+CRP,PAR+CLR,and WBC+PAR+CLR exhibit significant value for predicting the severity of brain injury in ACH patients and may serve as potential predictive tools for the severity of brain damage in patients with acute cerebral hemorrhage in high-altitude regions.

Objectives:This study aims to investigate the incidence,characteristics and clinical outcomes of vagal response(VR)during pulmonary vein isolation(PVI).Methods:A total of 702 patients with nonvalvular atrial fibrillation(AF)who received the first PVI radiofrequency ablation in Central China Fuwai Hospital from January 2022 to December 2023 were consecutively enrolled.PVI was initiated from right superior pulmonary vein(RSPV),followed by other pulmonary veins(PVs).The VR was defined as atrioventricular block(AVB),asystole or a 50%increase in the RR interval.Results:Among 702 patients with AF,380 patients(54.1%)were paroxysmal AF and 322 patients(45.9%)were persistent AF.77 patients(11.0%)developed 81 VR episodes,which were more common in paroxysmal group than in persistent AF group(19.5%vs.0.9%,P<0.001).VR manifestations included 51 sinus arrest(63.0%),26 sinus bradycardia(32.1%),and 4 atrioventricular block(AVB,4.9%).Most VR episodes were observed in the left superior ganglionated plexi(67[82.7%]).Paroxysmal AF(OR=18.667,95%CI:6.638-52.491,P<0.001),body mass index(BMI)≥28.0 kg/m2(OR=2.361,95%CI:1.376-4.051,P=0.002)and left ventricular ejection fraction(LVEF)≥62.0%(OR=1.964,95%CI:1.119-3.447,P=0.019)were independent risk factors of VR.During a mean of(13.0±7.1)months follow up,among paroxysmal AF patients,6 patients(8.1%)with VR and 33 patients(10.8%)without VR experienced AF recurrence(P=0.496).Kaplan-Meier curves estimated that the AF-free survival rate was similar between VR group and non-VR group among paroxysmal AF patients(log-rank P=0.735).Conclusions:The most common sites of VR when initiating PVI from right RSPV occur in left superior ganglionated plexi.Paroxysmal AF,BMI≥28.0 kg/m2 and LVEF≥62.0%are independent risk factors of VR.VR does not affect AF-free survival.
