Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.

Due to the extensive use of xylooligosaccharides (XOS) as functional food ingredients,many inferior goods and even adulterants are generally found in the market,which may pose a health hazard to certain populations.Chromatography method such as high-performance liquid chromatography (HPLC) and high-performance thin-layer chromatography (HPTLC) is traditionally applied for the quality analysis of XOS.However,it is time consuming due to the prolonged separation and pre-or post-derivatization procedure.In this study,a fast saccharide mapping method based on matrix-assisted laser desorption/time-of-flight mass spectrometry (MALDI-TOF-MS) was developed for the quality consistency analysis of 22 batches of XOS collected from different manufacturers in China.The time needed for saccharides analysis using MALDI-MS was less than 30 min for one plate,at least 6 times faster than that by the traditional HPTLC chromatography method.In addition,MALDI-MS possessed higher resolution for XOS with DP4-DP7 based on the difference of m/z,which is hardly separated using HPTLC.The results showed that XOS were present only in samples XY01-XY11,samples XY12-XY14 only consisted of hex oligo-saccharides,and samples XY15-XY22 were free of oligosaccharides.These indicate that the quality consistency of XOS products in the China market was poor,which should be carefully investigated.

Objective:To evaluate the changes of right ventricular function in patients with pneumoconiosis in different stages using three-dimensional speckle-tracking imaging (3D-STI) .Methods:In June 2020, 114 pneumoconiosis patients were selected as subjects, including 45 patients in stage Ⅰ pneumoconiosis group, 36 patients in stage Ⅱ pneumoconiosis group and 33 patients in stage Ⅲ pneumoconiosis group. Fifty healthy subjects were enrolled and served as control group. The longitudinal strain (LS) , radial strain (RS) and circumferential strain (CS) of free wall middle and basal segment of right ventricular were collected and compared. The right ventricular global longitudinal strain (GLS) , right ventricular global circumferential strain (GCS) , right ventricular ejection fraction (RVEF) , right ventricular global radial strain (GRS) , the rate of fractional area change (FAC) , the tricuspid valve systolic peak velocity (TVSPV) and the pulmonary artery systolic pressure (PASP) of each subject in the groups were collected and compared by 3D-STI.Results:The LS and RS of the right ventricular basal segment of patients in stage Ⅱ pneumoconiosis group were significantly lower than those of control group ( P<0.0125) . The LS, CS, RS of the right ventricular basal segment and RS of right ventricular middle segment of patients in stage Ⅲ pneumoconiosis group were significantly lower than those of control group ( P<0.0125) . The LS, CS and RS of the right ventricular basal segment of patients in stage Ⅰ pneumoconiosis group were significantly higher than those of stage Ⅲ pneumoconiosis group ( P<0.0125) , and the RS of the right ventricular basal segment of patients in stage Ⅱ pneumoconiosis group was significantly higher than that of stage Ⅲ pneumoconiosis group ( P<0.0125) . The levels of RVEF and GLS of patients in stage Ⅱ and stage Ⅲ pneumoconiosis group were significantly lower than those of control group ( P<0.0125) , while the levels of PASP were significantly higher than that of control group ( P<0.0125) . The levels of FAC and TVSPV of patients in stage Ⅲ pneumoconiosis group were significantly lower than those of control group ( P<0.0125) . The levels of RVEF, GLS and FAC of patients in stage Ⅰ pneumoconiosis group were significantly higher those that of stage Ⅲ pneumoconiosis group ( P<0.0125) , and the PASP level was significantly lower than that of stage Ⅲ pneumoconiosis group ( P<0.0125) . The FAC level of patients in stage Ⅱ pneumoconiosis group was significantly higher than that of stage Ⅲ pneumoconiosis group ( P<0.0125) . Conclusion:Patients with pneumoconiosis could experience a decline in right ventricular function at an early stage. The 3D-STI can accurately detect the GLS, GRS, GCS and hemodynamic changes of the right ventricular and evaluate the right ventricular function comprehensively and objectively. 3D-STI is of great significance for the early detection of right ventricular dysfunction in patients with pneumoconiosis.

Objective::This study aimed to estimate the proportion of non-obstructive coronary artery disease (CAD) patients in large percutaneous coronary intervention (PCI) centers in China.Methods::The study was conducted at 6 large PCI centers in China from January 1, 2013 to December 31, 2015. Demographic and clinical data were collected from medical records, prescription records, and laboratory reports of patients with symptoms of angina who underwent coronary angiography (CAG).Results::A total of 1713 patients were consecutively screened, 1600 of whom were included in the study. CAG showed that 300 patients had non-obstructive CAD while 1300 had obstructive CAD. Among the 300 patients with non-obstructive CAD, 203 displayed mild coronary stenosis (20%-49%) and 91 had normal coronary status (ie, <20% stenosis). Of the 1300 patients with obstructive CAD, 61.6% (801/1300) had typical symptoms of angina, compared with 49.3% (148/300) for patients with non-obstructive CAD. In addition, there were more women than men in the non-obstructive CAD group, whereas the reverse was observed among obstructive CAD patients.Conclusion::The prevalence of non-obstructive CAD in the Chinese population with coronary heart disease was estimated to be approximately 20%. Additionally, typical angina symptoms were correlated with obstructive CAD, whereas female gender was identified as a risk factor for non-obstructive CAD.

Objective To examine the prevalence of obstructive sleep apnea (OSA) in patients with acute coronary syndrome (ACS),and to evaluate the relationship of OSA with inflammatory biomarkers in ACS patients.Methods Patients with ACS treated at Beijing Anzhen Hopital from June 2015 to May 2017 were enrolled.Subjects were evaluated for OSA by sleep study,and were divided into a normal-mild OSA group (Apnea Hypopnea Index,AHI ＜ 15 times/h) and a moderate-severe OSA group (AHI ≥ 15 times/h).Laboratory examination and sleep study were monitored to analyze the effects of OSA on biomarkers by LSD-t test,Mann-whitney U test,or Chi-square test.Correlation analysis was performed to analyze the association of OSA with high sensitivity C-reactive protein (hs-CRP) by Spearman correlation anaylsis.Results A cohort of 836 patients with ACS were enrolled including 408 patients in the normal-mild OSA group and 428 patients in the moderate-severe OSA group.The levels of leukocyte(x 109L) [7.78 (6.33,9.86) vs 7.29 (6.01,9.16),P=0.006],neutrophils(× 109L) [5.05 (3.84,7.23)vs 4.80 (3.74,6.66),P=0.044],monocytes(x 109L) [0.42 (0.33,0.54) vs 0.39 (0.31,0.51),P=0.033],hsCRP(mg/L) [3.18 (1.10,11.52) vs 1.78 (0.65,6.46),P＜0.01],fibrinogen(g/L) [3.17 (2.87,3.74) vs 2.97 (2.59,3.50),P=0.002],and uric acid(μmol/L) [360 (302,422) vs 341(283,407),P=0.006] in the moderatesevere OSA group were significant higher than those in the normal-mild OSA group.AHI (correlation coefficient=0.171,R2=0.020,P＜0.01),ODI (correlation coefficient =0.201,R2=0.027,P＜0.01),and TSaO2 ＜ 90％ (correlation coefficient =0.105,R2=0.005,P＜0.01) were positively correlated with hs-CRP;minimal SaO2 (correlation coefficient=-0.100,R2=0.001,P=0.008) and mean SaO2 (correlation coefficient =-0.127,R2=0.006,P＜0.01) were negatively correlated with hs-CRP.Conclusions For patients with ACS,the level of inflammatory markers in the moderate-severe OSA group is significantly higher than that in the normal-mild OSA group.Hs-CRP is significantly associated with the severity of OSA.Diagnosis and monitoring of OSA should be considered in ACS management in the future.

Objective: To explore the association between hypothyroidism and sleep breathing disorders in patients with coronary heart disease (CHD). Methods: A total of 784 patients with CHD were consecutively enrolled at the Emergency & Critical Care Center of Beijing Anzhen Hospital from June 2015 to May 2017. According to thyroid function test results, patients were divided into hypothyroidism group (79 cases) and non-hypothyroidism group (705 cases). All patients had undergone sleep monitoring. The sleep apnea status was compared between the two groups. Multivariate logistic regression and linear regression models were used to analyze the association between hypothyroidism and sleep breathing disorders in patients with CHD. Results: The proportion of females, mean body weight and body mass index in the hypothyroidism group were higher than those in the non-hypothyroidism group [26.6% vs.16.2%, (78.6±11.6) kg vs. (75.7±12.0) kg, (27.7±3.2) kg/m² vs. (26.6±3.5) kg/m², all P<0.05]. Patients in hypothyroidism group had a decreased average oxygen saturation (SaO₂) compared with patients in non-hypothyroidism group [ (93.2±2.9) % vs. (93.9±2.0) %, P=0.030]. In addition, events of hypoventilation in hypothyroidism group were significantly higher than those in non-hypothyroidism group[92.5 (45.8, 758.3) times vs. 68.0 (33.0, 125.0) times, P=0.013]. There were no significant differences in apnea hypopnea index, diagnosis of obstructive sleep apnea and other sleep breathing parameters between the two groups (P>0.05). A multiple linear regression analysis found that in patients with CHD, the correlation between hypothyroidism and average sleep SaO₂ was significant (β=-0.508, 95%CI -0.989--0.026, P=0.039). Conclusions: CHD patients with hypothyroidism had a lower sleep average SaO₂, and a higher sleep hypopnea events. There is a correlation between hypothyroidism and sleep hypoxia in patients with CHD.

Objective: To investigate the impact of moderate/severe obstructive sleep apnea (OSA) on the prognosis of acute myocardial infarction. Methods: We prospectively selected patients with acute myocardial infarction (AMI) who were hospitalized at the Emergency Critical Care Center of Beijing Anzhen Hospital from June 2015 to May 2017. Patients who met the inclusion criteria were examined with portable sleep respiration monitoring. Patients were divided into moderate/severe OSA group (apnea-hypopnea index (AHI)≥15 beats/hour) and no/mild OSA group (AHI<15 beats/hour) according to sleep AHI. The incidence of major adverse cerebrovascular events (MACCE) after discharge was compared between the two groups, and the independent risk factors of MACCE were analyzed. Results: A total of 432 patients were enrolled in this study, including 211 moderate/severe OSA patients (48.8%). Compared with no/mild OSA group,patients with moderate/severe OSA had higher body mass index ((27.17±3.22) kg/m² vs. (25.55±3.44) kg/m², t=-5.033,P<0.001), higher proportion of history of percutaneous coronary intervention (PCI) (18.5%(39/211) vs. 8.6%(19/221), χ²=9.076,P=0.003), and higher proportion of 3-vessel disease (31.3%(66/211) vs. 24.9%(55/221), χ²=10.196,P=0.017). The median follow-up time was 1.0 (0.7, 1.7) years. The incidence of MACCE in the moderate/severe OSA and no/mild group was 19.9%(42/211) and 11.3%(25/221), respectively. Kaplan-Meier analysis showed a higher cumulative risk of MACCE in patients with moderate/severe OSA (log-rank test,χ²=5.467, P=0.019). Multivariate Cox regression analysis showed that moderate/severe OSA (HR=1.915, 95%CI 1.016-3.611, P=0.045) and diabetes mellitus (HR=1.819, 95%CI 1.022-3.238, P=0.042) were independent risk factors for MACCE at 1 year post discharge in patients with AMI. Conclusions: Nearly half of AMI patients are complicated with moderate/severe OSA in this patient cohort. Coronary artery disease is more severe in AMI patients complicating with moderate/severe OSA. Moderate/severe OSA is an independent risk factor for MACCE at 1 year after discharge in patients with AMI. Whether the prognosis of AMI can be improved by intervention of OSA remains to be investigated. Trial Registration Clinical Trial.gov, NCT03362385.

Objective To find out the relationship between the fatigue level,environment and mental status by exploring the differences in field army soldiers,naval shipboard personnel and cadets,so as to provide scientific evidences for:the promotion of health of the 3 military populations; the development of practical recommendations and countermeasures in the medical support for the 3 military populations; improvemcnt of their life quality; and most importantly their utter devotion to national defense.Methods Questionnaires were conducted among the 3 military populations (field army soldiers,naval shipboard personnel and cadets) by using "the Fatigue Symptoms Questionnaire" (FSQ),"the Simplified Coping Style Questionnaire" (SCSQ) and " the Automatic Thoughts Questionnaire" (ATQ).The data acquired were analyzed by SPSS21 software package.Results The rank of order for the seriousness of fatigue was:first the soldiers,second the naval shipboard personnel and last the cadets.From the standpoint of physical factor,soldiers showed the highest level of fatigue,followed by naval shipboard personnel and cadets.From the aspect of mental factor,shipboard personnel displayed the highest level of fatigue,followed by soldiers and cadets.In terms of sensory nerve fatigue,the rank of order for the seriousness of fatigue was:first the soldiers,second the shipboard personnel and last the cadets.For positive coping style,the rank of order from the highest to the lowest were:cadets,shipboard personnel and soldiers.The rank of order for negative coping style from the highest to the lowest was:soldiers,cadets and shipboard personnel.Conclusions The seriousness of fatigue in 3 military populations was significantly different,which might be correlated with their coping styles.
