Objective To observe the incidence of pericardial tamponade(PT)after left atrial appendage closure(LAAC)in patients with non-valvular atrial fibrillation(NVAF),and to explore its related factors and outcomes.Methods NVAF patients who were hospitalized and treated with LAAC in Department of Cardiology of our hospital from August 2014 to March 2023 were selected for the study.The general clinical data,preoperative transthoracic echocardiography and transesophageal echocardiography data,results of routine preoperative laboratory tests,intraoperative data and follow-up data of the patients were collected through the hospital medical record management system.The enrolled patients were classified into the non-PT group(n=8)and the PT group(n =1184)according to whether PT occurred after LAAC or not.The incidence of PT,related risk factors and outcomes were statistically analyzed.Results This study included 639 males(53.6%)and 553 females(46.4%),with an average age of 68.1±9.65 years.The CHA2 DS2-VASc score was 4.51±1.72,and the HAS-BLED score was 3.36±1.09.PT occurred in 8 cases(0.67%),among them,6 cases occurred 1 to 33 h after LAAC,and 2 cases occurred on day 19 and day 27 after LAAC.As for the results of transesophageal echocardiography(TEE)and LAA angiography,compared with the non-PT group,the PT group had the significantly larger maximum caliber of the LAA(P=0.025,P=0.015),smaller maximum depth of the LAA(P=0.028,P=0.031),and lower success rate of one-time placement of the occluder(P=0.031);The occluder compression rate of the PT group was significantly greater than that of the non-PT group(P=0.046).Multivariate analysis showed that larger maximum diameter of LAA,smaller average effective depth of LAA and larger compression rate of occluder were the main risk factors for PT.All the 8 PT patients were cured by stopping antithrombotic drugs,pericardiocentesis or surgical drainage.During a mean follow-up of 39±27 months,there were no device-related thrombosis(DRT),ischemic stroke,systemic embolism and other complications in the PT group.Conclusion The incidence of PT after LAAC is low,which is related to the large diameter of LAA,the relatively insufficient depth of the LAA and the large compression rate of the occlude.PT can be cured by stopping antithrombotic drugs and pericardiocentesis/surgical drainage.

Objective To explore the influence of gender on the prognosis of patients with atrial fibrillation(AF)undergoing left atrial appendage occlusion(LAAO).Methods All non-valvular AF patients who were admitted in our hospital and underwent LAAO from August 2014 to August 2021 were enrolled and grouped according to gender.Their general information,including gender,age,comorbid underlying diseases,and results of transthoracic echocardiography and transesophageal echocardiography(TEE)were collected.The incidences of device-related thrombosis(DRT),pericardial tamponade,stroke,bleeding,hospitalization for heart failure,and cardiac death were recorded during follow-up.The influence of gender on the prognosis of these patients was analyzed.Results There were totally 673 patients with non-valvular AF were enrolled,including 366 males and 307 females,at a mean age of 68.2±9.4 years.When compared with the male patients,the female ones had a higher CHA2DS2-VASc score(P＜0.01),but smaller proportions of history of stroke,average compression ratio of occluders,and incidence of residual shunt(＜3 mm)after occlusion(P＜0.05).In 45～60 d after surgery,TEE revealed that there were 17 cases of DRT,including 8 males(2.2％)and 9 females(2.9％),though without statistical difference between the groups.Among the 17 DRT cases,1 experienced stroke,and the incidence of stroke was 5.9％in those with DRT and 0.5％without.There were 4 cases of postoperative pericardial tamponade,including 1 in the male group and 3 in the female group(no significant difference),and all of them were improved after pericardial puncture and fluid extraction.During the follow-up period of 40.2±20.5 months,no obvious differences were observed between the 2 groups in terms of stroke,bleeding,hospitalization for heart failure,and cardiogenic death.Conclusion Gender shows no significant effect on the prognosis of patients with non-valvular AF after LAAO.

TCM believes that spleen deficiency is the root cause of emotional abnormalities in chronic fatigue syndrome (CFS), and clinical treatment often involves the heart, liver and kidney. TCM therapy has a significant efficacy in CFS emotional abnormalities. It is mostly treated with oral administration of TCM, acupuncture, moxibustion and massage therapy. It may play a therapeutic role by improving oxidative stress and immune inflammation, regulating nerve-endocrine, controlling energy metabolism and other ways. It is suggested to establish the syndrome differentiation standard of CFS emotional abnormality in the future, so as to improve the accuracy of syndrome differentiation and treatment; form a perfect treatment guide or expert consensus to guide the standardized application of various internal and external treatment methods; explore objective indicators based on the pathogenesis, and focus on the morphological and functional changes of disease target brain regions with the help of neuroimaging techniques, so as to improve the diagnosis and prognosis evaluation of CFS; based on the guidance of TCM theory, improve the CFS emotional abnormal animal modeling method.

Objective To investigate the influence of serum cystatin C (Cys-C) and hypersensitivity C-reactive protein (hs-CRP) levels on the 3-year survival of patients undergoing maintenance hemodialysis (MHD). Methods A total of 358 patients with chronic renal failure who underwent MHD at the Second Affiliated Hospital of Nantong University from April 2011 to October 2020 were selected as study subjects. General clinical data, pre-dialysis laboratory test indicators, and echocardiographic indicators 3 months after dialysis were recorded. The survival status of patients after 3 years of dialysis was followed up, and the general clinical data, pre-dialysis laboratory test indicators, and echocardiographic indicators 3 months after dialysis were compared between surviving and deceased patients. Univariate and multivariate Cox regression analyses were performed to screen influencing factors of 3-year survival in MHD patients. Results At the 3-year follow-up, of the 302 MHD patients' 203 survived, and 99 died. Statistically significant differences were observed in age, primary disease, diabetes status, congestive heart failure, statin use, antiplatelet drug use, diuretic use, dialysis mode, estimated glomerular filtration rate (eGFR) and gamma-glutamyl transferase (GGT), alkaline phosphatase (AKP), total bilirubin (TBIL), β₂-microglobulin (β₂-MG), creatinine (Cr), low-density lipoprotein cholesterol (LDL-C), hypersensitive C-reactive protein (hs-CRP), and serum phosphorus (P) levels between surviving patients and deaths(P < 0.05 or P < 0.01). Univariate Cox regression results showed that age of MHD patients, primary disease (diabetic nephropathy, hypertensive nephropathy, polycystic kidney disease, others), comorbidities(diabetes, congestive heart failure, other cardiovascular diseases), drug use (statins, antiplatelet drugs), dialysis method (hemodialysis, hemodialysis + perfusion), laboratory test indicators [GGT, AKP, TBIL, total bile acid (TBA), albumin (ALB), Cr, Cys-C, eGFR, apolipoprotein A (APO-A), hs-CRP]were all influential factors of 3-year survival rate of MHD patients. Multivariate Cox regression analysis revealed that age, primary disease, other cardiovascular diseases, dialysis mode, AKP, ALB, TBIL, Cys-C, and hs-CRP were significant influencing factors for the survival of patients with chronic renal failure (P < 0.05). Conclusion Serum Cys-C and hs-CRP levels before MHD in patients with chronic renal failure may be associated with their 3-year survival after dialysis treatment. High serum Cys-C may reduce the risk of poor clinical prognosis, while high serum hs-CRP may increase the risk of poor clinical prognosis.

Traditional Chinese Medicine (TCM) external therapy for sleep disorder of chronic fatigue syndrome (CFS) has good anti-fatigue effect and can improve sleep quality of patients. The treatment for sleep disorders of CFS with TCM external treatment mainly adopts acupuncture, moxibustion, massage, TCM bath, transcutaneous acupoint electrical stimulation and auricular point sticking, etc., or alone, or comprehensive application, or combined with oral Chinese materia medica. The appropriate treatment method can be selected according to the patients' condition and compliance, which reflects the unique advantages of TCM syndrome differentiation and treatment and the treatment according to people and time. The existing research still needs to further form a standardized and recognized diagnosis and treatment system, so as to better guide clinical popularization and application.

Objective:To summarize the clinical experience of treating patients with severe acute organic fluorine poisoning using extracorporeal membrane oxygenation (ECMO).Methods:In January 2021, an acute mass organic fluorine gas poisoning incident occurred in Quzhou, Zhejiang Province. The clinical data of 4 severe patients with acute poisoning of organic fluorine treated by ECMO in our hospital were retrospectively analyzed, and the epidemiological characteristics, clinical symptoms, signs, the abnormal laboratory studies/examinations, and treatments of this kind poisoning patients, especially, the treatment pattern, support time, complications, and outcomes of ECMO were collected and analyzed.Results:All the 4 patients were male, with an average age of (52±9) years, and all of them came to the emergency department complaining chest tightness, cough and pharyngeal discomfort 6 h after exposure by inhalation. The patient’s condition progressed rapidly with severe acute respiratory failure and circulatory failure as the prominent manifestations. The mechanical ventilations were performed (13.0±4.8) h after poisoning, and ECMO treatment was performed (15.5±5.3) h after poisoning. Among them, 2 patients were treated using venoarterial (VA) ECMO, and 2 patients using venovenous (VV) ECMO, but 1 patient was converted to VA-ECMO 8 h later. The duration of ECMO support for the patients was (8.8±3.6) d. The duration of mechanical ventilation was (23.0±28.7) d and stay in intensive care unit was (42.0±55.4) d. Among them, one patient was transferred to a specialized rehabilitation hospital after the amputation surgery due to lower limb necrosis after VA-ECMO support, and the remaining 3 patients were discharged after recovery.Conclusions:ECMO support might have the irreplaceable value in the treatment of patients with severe acute organic fluorine poisoning, and should be considered as one of the reserves of regional health care system in dealing with public health emergencies.

Objective:To analyze the epidemic status and characteristics of human brucellosis in Ordos City, and to provide basis for formulating perfect prevention and control countermeasures of brucellosis.Methods:The data of reported human brucellosis cases in Ordos City from 2016 to 2020 were collected through the Chinese Disease Prevention and Control Information System. Descriptive epidemiological method was used to analyze the distributions of time, region and population.Results:Totally 2 861 cases of human brucellosis were reported in Ordos City from 2016 to 2020. The average annual incidence rate was 27.68/100 000 and no deaths. The incidence rate of human brucellosis decreased year by year from 2016 to 2018 (24.11/100 000, 20.82/100 000, 20.11/100 000). But the incidence rate began to pick up in 2019 (24.59/100 000) and rose to 48.53/100 000 in 2020. The incidence peak was from March to August (1 882 cases). The cases had been reported in all over 9 banners (districts) of the city. The cumulative number of reported cases from more to less was Hangjin Banner, Dalat Banner, Otog Front Banner, Jungar Banner, Otog Banner, Dongsheng District, Wushen County, Ejin Horo Banner and Kangbashi District. The cases were predominantly male, and the sex ratio of male to female was 2.23∶1.00 (1 974 ∶ 887). The onset was mainly young and middle-aged adults, and the age was mainly 30-69 years old (2 541 cases). Farmers accounted for 65.26% (1 867 cases) in all reported cases, followed by herdsmen, accounting for 18.98% (543 cases).Conclusions:There is an obvious upward trend of human brucellosis in Ordos City in recent years, mainly among young and middle-aged male farmers. Health education for key populations should be strengthened, as well as personal protection during high-risk operations.
