Under the current situation of "low prevalence and low infection" of schistosomiasis in China, and to provide a basis for achieving the goal of eliminating schistosomiasis by 2030 proposed by the Healthy China Action (2019 - 2030) as scheduled, the Hunan Provincial Corps Hospital of the Chinese People's Armed Police Force established a schistosomiasis monitoring and early warning index system based on the previous studies on schistosomiasis early warning index system and the recent literature analysis, combined with the current potential risk factors affecting the transmission and prevalence of schistosomiasis, and organized two rounds of expert consultation and carried out project promotion meetings. The experts reached a consensus on the comprehensiveness and practicability of the index system, aiming to lay a solid foundation for construction of China's schistosomiasis prevention and control early warning system.

Objective To explore the correlation of occurrence of major adverse cardiovascular events(MACE)with QRS-T angle,N-terminal pro-B-type natriuretic peptide(NT-proBNP)and fibrinogen(FIB)levels and platelet/lymphocyte ratio(PLR)in patients with acute myocardial in-farction(AMI)after percutaneous coronary intervention(PCI).Methods A retrospectively analy-sis was conducted on 98 AMI patients undergoing PCI in our department from May 2020 to June 2022.According to the occurrence of MACE or not,they were divided into MACE group(25 cases)and non-MACE group(73 cases).The general data and QRS-T angle,PLR,and Fib and NT-proBNP levels were compared between the two groups.Univariate logistic regression analysis and ROC curve analysis were used to analyze the influencing factors and predictive efficacy for MACE occurrence in AMI patients after PCI.Results Significantly larger QRS-T angle and PLR,and higher FIB and NT-proBNP levels were observed in the MACE group than the non-MACE group(P＜0.05,P＜0.01).Univariate logistic regression analysis showed that RS-T angle(OR=1.086,95％CI:1.043-1.131,P=0.000),PLR(OR=1.184,95％CI:1.102-1.272,P=0.000)and NT-proBNP level(OR=1.009,95％CI:1.004-1.014,P=0.000)were influencing factors for MACE occurrence in AMI patients after PCI.ROC curve analysis indicated that the AUC value of QRS-T angle,PLR and NT-proBNP level in predicting MACE after PCI in AMI patients was 0.822,0.870 and 0.907,with a sensitivity of 76.00％,76.00％and 84.00％,and a specificity of 72.60％,89.04％and 94.52％,respectively.Conclusion QRS-T angle,PLR and NT-proBNP are the influencing factors of MACE in AMI patients after PCI,and they have good predictive value.

Objective To analyze the relationship of serum S100 calcium binding protein A4(S100A4)and pentraxin-3(PTX3)levels with left atrial appendage thrombosis in patients with NVAF.Methods A total of 120 elderly NVAF patients treated in our hospital from March 2020 to March 2023 were enrolled in this study.According to their echocardiograms,they were divided into a left atrial appendage thrombosis group(40 cases)and a non-thrombosis group(80 cases).Serum S100A4 and PTX3 levels were detected.Spearman correlation analysis was applied to ana-lyze the relationship between serum S100A4 and PTX3 levels and left atrial appendage thrombo-sis.Logistic regression analysis was conducted to analyze the factors affecting left atrial appendage thrombosis.Results The serum levels of S100A4 and PTX3 were higher in the thrombosis group than the non-thrombosis group(P＜0.01).The serum levels of S100A4 and PTX3 were positively correlated with left atrial appendage thrombosis(r=0.497,P=0.000;r=0.555,P=0.000).Heart failure,CHA2DS2-VASc score,B-type natriuretic peptide,uric acid,S100A4 and PTX3 were risk factors for left atrial appendage thrombosis in NVAF patients(P＜0.05,P＜0.01).Combination of serum S100A4 and PTX3 in predicting left atrial appendage thrombosis formation in NVAF patients had an AUC value of of 0.949(95％CI:0.893-0.981).Conclusion Serum S100A4 and PTX3 levels are increased in NVAF patients,they are related to left atrial appendage thrombosis,and their serum levels have certain predictive value for left atrial appendage thrombosis.

Objective:To summarize and analyze the clinical data of Chinese patients with colony-stimulating factor 1 receptor (CSF1R)-related leukoencephalopathy, and clarify the phenotypic and genetic characteristics of Chinese patients.Methods:Medical history of patients with CSF1R-related leukoencephalopathy diagnosed from April 1, 2018 to January 31, 2021 in the department of neurology of 22 hospitals in China was collected, and scores of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Scale (MoCA), magnetic resonance severity scale were evaluated. Group comparison was performed between male and female patients.Results:A total of 62 patients were included, and the male-female ratio was 1∶1.95. The age of onset was (40.35±8.42) years. Cognitive impairment (82.3%, 51/62) and motor symptoms (77.4%,48/62) were the most common symptoms. The MMSE and MoCA scores were 18.79±7.16 and 13.96±7.23, respectively, and the scores of two scales in male patients (22.06±5.31 and 18.08±5.60) were significantly higher than those in females (15.53±7.41 , t=2.954, P=0.006; 10.15±6.26, t=3.328 , P=0.003). The most common radiographic feature was bilateral asymmetric white matter changes (100.0%), and the magnetic resonance imaging severity scale score was 27.42±11.40, while the white matter lesion score of females (22.94±8.39) was significantly higher than that of males (17.62±8.74 , t=-2.221, P<0.05). A total of 36 CSF1R gene mutations were found in this study, among which c.2381T>C/p.I794T was the hotspot mutation that carried by 17.9% (10/56) of the probands. Conclusions:The core phenotypic characteristics of CSF1R-related leukoencephalopathy in China are progressive motor and cognitive impairment, with bilateral asymmetrical white matter changes. In addition, there exist gender differences clinically, with severer cognitive impairment and imaging changes in female patients. Thirty-six CSF1R gene mutations were found in this study, and c.2381T>C/p. I794T was the hotspot mutation.

From May 2012 to May 2013, 60 chronic male smokers received an intravenous infusion of dexmedetomidine 1 μg/kg (Group D, n=30) or an equal volume of normal saline (Group C, n=30) before anesthesia induction.At time of dexmedetomidine or normal saline dosing , after induction of anesthesia, 1 and 3 min after intubation, the heart rates and rate-pressure products were significantly lower in Group D than Group C ( P<0.05 ).Thus the dosing of dexmedetomidine before anesthesia induction could suppress the cardiovascular responses of endotracheal intubation in chronic smokers and avoid increasing myocardial oxygen consumption so as to protect heart functions.

OBJECTIVE: To determine the effect of lung protection mechanical ventilation on respiratory function in the elderly undergoing spinal fusion. METHODS: Sixty 70-85 year old patients, ASA class II or III, undergoing spinal fusion were randomly assigned into 2 groups (30 in each group): a protection mechanical ventilation group (group P) and a conventional mechanical ventilation group (group C). Low VT and low level positive end expiratory pressure (PEEP) mechanical ventilation were applied in group P (VT=6mL/kg, RR=12-18 b/min, I:E=1:2, PEEP=10 cmH2O, alveolar recruitment performed once every 15 min), while traditional ventilation was used in group C ( VT=10-12 mL/kg, RR=12 b/min, I:E=1:2). Arterial blood samples were taken and pH, PaO2, PaCO2, PaO2/FiO2, A-aDO2, HR, SBP, DBP and CVP were recorded before the operation (T0), 1 h after tracheal intubation (T1), tracheal extubation immediately (T2), 1 h after tracheal extubation (T3), 1 d, 2 d, and 3 d after the operation (T4, T5, and T6). The pulmonary complication was also examined 1 d after the operation. RESULTS: At T1, T2, T3, T4 and T5, PaO2 and PaO2/FiO2 in group P were higher than those in group C, but A-aDO2 in group P was lower than that in group C. Five patients had bronchitis, 5 had hyoxemia, and 3 had atelectasis in group C, but 2 bronchitis in group P. The incidence of pulmonary complication was 43.3% in group C and 6.6% in group P. There was no significant difference in HR, SBP, DBP and CVP between the 2 groups. CONCLUSION Lung protection mechanical ventilation improves the arterial oxygenation and accelerates the recovery of respiratory functions in elderly patients after spinal fusion operation, with no influence on hemodynamics.
