Objective To analyze the pathogenic composition of hand, foot and mouth disease (HFMD) cases and the antibody level of enterovirus 71 (EV-A71) in healthy people in Xi'an in 2022, so as to provide evidence for the prevention and control of HFMD. Methods Anal swabs or stool specimens of HFMD cases were collected. RT-PCR was used to detect enterovirus (EV) and serotype was identified. Enzyme-linked immunosorbent assay (ELISA) was used to detect EV-A71 IgG antibody levels in healthy people. Results A total of 172 positive cases were detected from 274 HFMD clinical specimens with a total detection rate of 62.77%, including 1 case of EV-A71 (0.58%), 95 cases of CV-A16 (55.23%), 64 cases of CV-A6 (37.21%), and 1 case of CV-A10(0.58%). CV-A16 was the dominant pathogen in spring and summer, and CV-A6 was the dominant pathogen in autumn and winter(χ2= 64.376,P<0.001). The age of HFMD cases caused by CV-A16 was older than the cases caused by CV-A6(t = 2.709,P = 0.007). The positive rate of EV-A71 IgG antibodies in healthy people was 36.92% (168/455). The positive rate of EV-A71 IgG antibodies in men (32.35%) was lower than that in women (43.72%), and the difference was statistically significant (χ2= 6.605 , P = 0.014). The positive rate of EV-A71 IgG antibodies in people of all ages ranged from 21.95% to 54.78%, and the difference was statistically significant (χ2= 27.623 , P<0.001). Conclusion The main pathogens of hand, foot and mouth disease in Xi'an in 2022 are CV-A16 and CV-A6 . The positive rate of EV-A71 IgG antibodies in children under 5 years old is low , and EV-A71 vaccination should be strengthened.

Objective:To compare and analyze the correlation between two kinds of point-of-care testing (POCT) instruments and Roche electrochemiluminescence instrument in detecting myocardial biomarkers,so as to provide reference for the selection of POCT instruments in clinical testing. Methods:A total of twenty patient's samples were selected,which concentration range covered the reportable range of detection results. Two kinds of POCT instruments (named respectively A and B) were used to detect the concentrations of plasma myoglobin (Myo),creatine kinase isoenzyme mass (CK-MB mass),cardiac troponin I(cTnI),and N-terminal fragment of B-type natriuretic peptide (NT-proBNP)/Brain natriuretic peptide (BNP). The results of the electrochemiluminescence instrument were used as reference,and Pearson correlation analysis and Kappa test evaluation were used to evaluate respectively the correlation and consistency of the detected results between the two kinds of POCT instruments and Roche electrochemiluminescence instrument. Results:Our study demonstrated that there were good correlations in the detected results of Myo,CK-MB mass,cTnI,NT-proBNP/BNP between the instrument A and Roche electrochemiluminescence instrument,and between the instrument B and Roche electrochemiluminescence instrument (rinstrumentA=0.994,0.989,0.917,0.996,rinstrumentB=0.928,0.934,0.883,0.977,P<0.05),respectively. In the comparisons about consistencies,the concordance rates between instrument A and electrochemiluminescence instrument were respectively 90%,100%,70% and 100% in detecting Myo,CK-MB,cTnI and NT-proBNP,and the concordance rates between instrument B and electrochemiluminescence instrument were respectively 90%,100%,70% and 100% in detecting them. Both two kinds of POCT instruments had favorable consistencies with Roche electrochemiluminescence instrument (Kappainstrument A=0.798,1.00,0.429,1.00,Kappainstrument B=0.794,0.886,0.429,1.00),respectively. The precisions of both instruments were less than 10%. Conclusion:Both two kinds of POCT instruments can meet the requirements of clinical test,which have favorable correlations with electrochemiluminescence instrument in detecting myocardial biomarkers.

Objective:To assess the diagnostic value of ATP stress myocardial perfusion imaging(MPI) in detecting coronary heart disease (CAD) with quantitative coronary angiography (QCA) as the gold standard.Methods:A total of 95 consecutive patients (65 males, 30 females, age (56.2±8.5) years) who underwent ATP stress/rest MPI and coronary angiography (CAG) within one month in Fuwai Hospital, Chinese Academy of Medical Sciences from May 2018 to December 2018 were enrolled prospectively. The adverse reactions of ATP stress test were observed. Semi-quantitative analysis was performed on MPI results, and the summed stress score (SSS), summed rest score (SRS) and summed difference score (SDS) were obtained. Quantitative analysis was performed on CAG images, and the degree of QCA coronary artery stenosis was analyzed. Using QCA as the gold standard, the diagnostic efficiency of ATP stress MPI was calculated. Pearson correlation analysis was performed to analyzed the relationship between SSS and the degree of QCA coronary artery stenosis.Results:In 95 cases, the incidence of adverse reactions in ATP stress test was 73.7%(70/95), which could be relieved automatically after drug withdrawal. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ATP stress MPI in diagnosing coronary artery stenosis ≥50% were 45.3%(24/53), 81.0%(34/42), 75.0%(24/32), 54.0%(34/63) and 61.1%(58/95) respectively, which were 15/16, 78.5%(62/79), 46.9%(15/32), 98.4%(62/63), and 81.1%(77/95) respectively in diagnosing coronary artery stenosis ≥70%. There was moderate correlation between SSS and the degree of QCA coronary artery stenosis ( r=0.418, P=0.017). Conclusion:ATP stress MPI has a clinical value in the diagnosis of myocardial ischemia in CAD.

Objective:To analyze the etiological and epidemiological characteristics of hand, foot and mouth disease (HFMD) in Xi′an from 2019 to 2021, so as to provide evidence for the prevention and control of HFMD.Methods:Stool specimens and anal swabs were collected from patients with HFMD. Enteroviruses (EVs) including enterovirus 71 (EV71), coxsackievirus A16 (CVA16), CVA6 and CVA10 were detected by RT-PCR. Excel 2007 and SPSS18.0 software were used for data collection and statistical analysis, respectively. The epidemiological data of HFMD cases were analyzed by descriptive epidemiology method. The VP1 gene sequence of the representative strain of each CVA6 genotype was downloaded. Phylogenetic trees were constructed using MEGA X software and the genetic characteristics were analyzed.Results:A total of 1 531 HFMD cases were involved and 1 365 were positive for EVs with a positive rate of 89.16%. The detection rates of EV71, CVA16, CVA6, CVA10 and other EVs were 1.31% (20/1 531), 32.46% (497/1 531), 38.47% (589/1 531), 5.09% (78/1 531) and 11.23% (172/1 531), respectively. There were significant differences in the pathogen composition in HFMD cases of different clinical types (χ 2=46.14, P<0.01) and occupations (χ 2=34.65, P<0.01) as well as in different years (χ 2=462.86, P<0.01). The average age was greater in patients with CVA16 infection than in those with CVA6 or CVA10 infection ( F=6.00, P<0.01). In 2019, the HFMD cases were mainly caused by CVA16, while in 2020 and 2021, the main pathogen was CVA6. Enterovirus-positive cases showed a bimodal distribution with the main peak from May to July and the secondary peak from September to November. CVA16 was the predominant pathogen in spring and summer, and CVA6 was the predominant pathogen in autumn. CVA6 was the dominant pathogen in eight districts and counties of Xi′an; CVA16 was the dominant pathogen in six districts and counties; CVA6 and CVA16 co-circulated in one district. The CVA6 isolates belonged to two evolutionary branches of D3a subtype. Conclusions:CVA6 and CVA16 were the prevalent pathogens of HFMD and CVA6 subtype D3a circulated in Xi′an from 2019 to 2021. The pathogen composition of HFMD cases showed obvious differences in population, time and regional distribution.

Pharmacy active consultation refers to the spontaneous activity that clinical pharmacists take the initiative to go to clinical departments to help doctors solve problems related to drug use in clinical practice ,put forward drug treatment suggestions or provide pharmaceutical services ,and form medical documents . The difference between pharmacy active consultation and pharmacy consultation is that the latter is generally proposed by the clinician ,who sends a consultation invitation to the pharmacy department in the hospital information system ,and the clinical pharmacist will go to the consultation after receiving it ,while the former is a pharmaceutical service mode that the clinical pharmacist takes the initiative to carry out in the clinical department . On the basis of routine pharmacy active consultation ,clinical pharmacists in our hospital also further carried out a special active consultation mode (including prompt special active consultation for patients with multidrug resistance bacteria positive ,active monitoring and intervention for patients with drug -induced liver injury ),and patient pharmaceutical supervision in the form of return visit of pharmacy active consultation . Pharmacy active consultation and its special active consultation possess the characteristics of initiative , early and extensive coverage ,as a supplement to resident clinical pharmacy services . Pharmacy active consultation could help the pharmacy department to improve service efficiency ,provide a new perspective for medical institutions to carry out efficient pharmaceutical services ,and supply new ideas for the reform of pharmaceutical services in China .

Objective:To investigate the predictive value of neutrophil-lymphocyte ratio (NLR) for Trousseau’s syndrome (TS) in patients with acute multiple cerebral infarctions (AMCI).Methods:The patients with AMCI in Suzhou Kowloon Hospital, Shanghai Jiaotong University School of Medicine from July 2013 to March 2022 were retrospectively enrolled. The demographic and baseline clinical data of patients with TS and those without TS were compared. Multivariate logistic regression analysis was used to determine the independent influencing factors of TS-AMCI, and receiver operating characteristic (ROC) curve was used to evaluate the predictive value of NLR for TS-AMCI. Results:A total of 59 patients with AMCI were enrolled, including 43 males and 16 females, aged 64.9±14.0 years. There were 16 patients in the TS-AMCI group and 43 in the non-TS-AMCI group. The proportions of patients with diabetes mellitus, hypertension and previous stroke or transient ischemic attack in the TS-AMCI group were significantly lower than those in the non-TS-AMCI group (all P<0.05), while the proportion of patients with ischemic heart disease were significantly higher than that in the non-TS-AMCI group ( P<0.05). The proportion of patients with bilateral infarction in the TS-AMCI group was significantly higher than that in the non-TS-AMCI group ( P<0.001). The D-dimer, NLR, white blood cell count, neutrophil count, monocyte count, percentage of neutrophils, total cholesterol and low-density lipoprotein cholesterol in the TS-AMCI group were significantly higher than those in the non-TS-AMCI group (all P<0.001), while the lymphocyte count, lymphocyte percentage, red blood cell count, hemoglobin and hematocrit were significantly lower than those in the non-TS-AMCI group (all P<0.001). Multivariate logistic regression analysis showed that high NLR was an independent predictor of TS-AMCI (odds ratio [ OR] 2.897, 95% confidence interval [ CI] 1.270-6.527; P=0.011), while high hemoglobin was independently negatively correlated with TS-AMCI ( OR 0.839, 95% CI 0.723-0.975; P=0.022). ROC curve analysis showed that the area under the curve of NLR for predicting TS-AMCI was 0.929 (95% CI 0.831-0.979; P<0.001). When the NLR cutoff value was 4.01, the corresponding Youden index was 0.744. At this time, the sensitivity and specificity were 100% and 74.42% respectively. Conclusion:NLR has high predictive value for TS-AMCI.

Objective:To explore the safety and efficiency of percutaneous coronary intervention (PCI) in maintenance hemodialysis patients combined with non-ST-segment elevation acute coronary syndrome (NSTE-ACS).Methods:The clinical data of 52 maintenance hemodialysis patients combined with NSTE-ACS from January 2010 to January 2015 in Dalian Central Hospital were retrospectively analyzed. Among of them, 25 patients were treated with common drugs (control group), and 27 patients were treated with common drugs combined with PCI (PCI group). The major adverse cardiac events (MACE) duration of hospital stay were record, including hemorrhage, malignant arrhythmia, new heart failure or aggravation, stroke and all-cause death. The dialysis complications within 1 month after treatment were recorded, including hypotension, arrhythmia, heart failure and angina pectoris. The patients were followed up for 12 months, the MACE 1, 6 and 12 months after treatment were recorded, including angina pectoris, heart failure and cardiac death.Results:Duration of hospital stay, the incidences of malignant arrhythmia and new heart failure or aggravation in PCI group were significantly lower than those in control group: 18.5% (5/27) vs. 44.0% (11/25) and 7.4% (2/27) vs. 32.0% (8/25), and there were statistical differences ( P<0.05); there were no statistical difference in the incidences of hemorrhage, stroke and all-cause death between the two groups ( P>0.05). The incidences of dialysis complications such as hypotension, arrhythmia, heart failure and angina pectoris within 1 month after treatment in PCI group were significantly lower than those in control group: 24.0% (6/25) vs. 56.5% (13/23), 16.0% (4/25) vs. 43.5% (10/23), 12.0% (3/25) vs. 47.8% (11/23) and 24.0% (6/25) vs. 52.2% (12/23), and there were statistical differences ( P<0.05 or <0.01). The follow-up results showed that the incidences of angina pectoris and heart failure 1, 6 and 12 months after treatment in PCI group were significantly lower than those in control group, angina pectoris: 28.0% (7/25) vs. 65.2% (15/23), 29.2% (7/24) vs. 76.2% (16/21) and 43.5% (10/23) vs. 17/17, heart failure: 16.0% (4/25) vs. 43.5% (10/23), 8.3% (2/24) vs. 33.3% (7/21) and 21.7% (5/23) vs. 10/17, and there were statistical differences ( P<0.05 or <0.01); there was no statistical difference in the incidence of cardiac death 1 and 6 months after treatment between two groups ( P>0.05), the incidence of cardiogenic death 12 months after treatment in PCI group was significantly lower than that in control group: 8.6% (2/23) vs. 9/17, and there was statistical difference ( P<0.01). Conclusions:PCI is safe and effective for maintenance hemodialysis patients combined with NSTE-ACS.

Objective:To investigate the evaluation value of one-stop whole-brain dynamic volume CT angiography and CT perfusion imaging (CTA-CTP) in the cynomolgus monkeys models of middle cerebral artery occlusion (MCAO).Methods:Ten adult cynomolgus monkeys were selected and examined by head and neck CTA-CTP and craniocerebral MRI to rule out craniocerebral space-occupying lesions or cerebrovascular malformation. Under guidance of digital substraction angiography (DSA), the right femoral artery was dissected and monkey autologous thrombosis was injected into the right middle cerebral artery (MCA) through microcatheter to prepare MCAO models. Whole brain DSA was performed intraoperatively to observe whether the model was successfully prepared, and head and neck CTA-CTP was performed 24 h and 7 d after modeling to determine the locations and brain blood flow changes of ischemic lesions. The monkeys were sacrificed 8 d after modeling, and the brain tissues were stained with 2,3,5-triphenyltetrazolium chloride (TTC).Results:Among the 10 cynomolgus monkeys, one was excluded because of preoperative cerebrovascular malformation, and one died of cerebral hernia caused by cerebral hemorrhage during the experiment. The remaining 8 MCAO models were successfully prepared. Intraoperative DSA orthography showed unclear M1 segment and distal branch of MCA. Brain CT scan 24 h and 7 d after modeling showed obvious cerebral ischemic lesions in the right MCA blood supply area, and the infarct extent 7 d after surgery was more obvious than that 24 h after surgery. CTA examination showed obvious blood flow interruption imaging in the in M1 segment of MCA on the right side, the distal vessels were not clearly displayed and the distal branches of the infarct side 7 d after surgery were obvious decreased as compared with those 24 h after surgery. CTP scan showed that the cerebral blood volume of the right cerebrum was obviously reduced as compared with that of the left cerebrum, which was consistent with the blood supply area of MCA; and the infarct cores and penumbra areas 7 d after surgery were obvious increased as compared with those 24 h after surgery. TTC staining showed that the ischemic lesions of the brain tissue on the slices were gray and involved multiple layers, and the range was roughly consistent with the infarction sites shown by DSA and CT imaging.Conclusion:One-stop whole brain dynamic volume CTA-CTP has good evaluation value in imaging findings in MCAO animal models.

Objective:To characterize the epidemiology of hand, foot and mouth disease (HFMD) cases caused by coxsackievirus group A type 6 (CV-A6) in Xi’an from 2016 to 2020 and provide evidence for the prevention and control of HFMD.Methods:The enterovirus (EV) types were identified using real-time RT-PCR. The data of HFMD cases were collected from the National Notifiable Infectious Diseases Reporting System of China Center for Disease Control and Prevention. Descriptive epidemiological method were used to analyze the distributions and the data were statistically analyzed with Excel 2007 and SPSS 18.0.Results:In the 4 034 HFMD cases, 17.85% had enterovirus group A type 71 (EV-A71) infections, 23.92% had coxsackievirus group A type 16 (CV-A16) infections, and 47.79% had other EV infections. 2 571 HFMD cases were randomly selected, including 1 268 other EV positive cases. The detection rate of CV-A6 in HFMD cases was 34.73% (893/2 571), and the constituent ratio of CV-A6 in other EV positive cases was 70.43% (893/1 268). The cases mainly occurred in children aged≤5 years (95.18%), more boys were affected than girls (1.47∶1). HFMD caused by CV-A6 was concentrated in April to June. Compared with EV-A71 and CV-A16, the clinical classification had significant difference in CV-A6 group ( χ2=139.55, P<0.001), but the ratio of sex and age-group had no significant difference ( F=2.74, P=0.065; χ2=2.43, P=0.297). Conclusions:The predominant pathogen of HFMD in Xi’an from 2016 to 2020 were other EV, among which CV-A6 accounted for the highest proportion in other EV positive cases. It is necessary to strengthen the prevention and control of HFMD caused by CV-A6 and carry out the surveillance for various pathogens of HFMD.
