Objective To compare the characteristics of digital subtraction angiography ( DSA) and compu-ted tomography angiography ( CTA) of moyamoya disease .Methods To analyze the characteristic of DSA and CTA in 29 cases with moyamoya disease ,including arterial occlusion ,arteriarctia,abnormal proliferation of vascular ,collat-eral circulation.Results There were no statistically significant differences between DSA and CTA in detecting arteri-al occlusion,arteriarctia(CTA 53 hemicerebrum,DSA 57 hemicerebrum)(χ2 =2.167,P>0.05),abnormal prolifera-tion of vascular (abnormal:CTA 41 hemicerebrum,DSA 45 hemicerebrum;normal:CTA 16 hemicerebrum,DSA 12 hemicerebrum)(χ2 =0.757,P>0.05).But there was statistically significant difference between DSA and CTA in detecting collateral circulation .Conclusion CTA is a good method to find out moyamoya disease .But DSA is better in discovery collateral circulation of moyamoya disease .

Objective To study the levels of serum C -reactive protein (CRP),plasma fibrinogen (Fib),D-dimmer(DD)in the first onset young patients with acute progressive cerebral infarction.Methods 42 first onset young patients with acute progressive cerebral infarction(PIS group),50 cases of non -acute progressive cerebral infarction(N -PIS group)and 90 healthy people(health control group)were enrolled.The levels of serum CRP, plasma Fib and DD were detected and compared.Results PIS group:CRP (3.764 ±0.832)mg /L,Fib (3.994 ± 0.851)g/L,DD (1.560 ±0.225)μg/mL;N -PIS group:CRP (2.573 ±0.657)mg/L,Fib (2.468 ±0.739)g/L, DD (0.740 ±0.162)μg/mL;health control group:CRP (1.725 ±0.326)mg/L,Fib (2.103 ±0.584)g/L,DD (0.450 ±0.131)μg/mL.The levels of serum CRP,plasma Fib and DD of PIS group were higher than the other two groups(CRP:PIS group vs.N -PIS group t =8.89,PIS group vs.health control group t =13.99,N -PIS vs.health control group t =8.55,all P <0.01;D -D:PIS group vs.N -PIS group t =23.82,PIS group vs.health control group t =29.46,N -PIS group vs.health control group t =12.59,all P <0.01;FIB:N -PIS group vs.health control group t =2.85,P <0.05,PIS group vs.N -PIS group t =10.06,PIS group vs.health control group t =13.48,all P <0.01).Conclusion The levels of serum CRP,plasma Fib and DD are related to acute progressive cerebral infarction.

Objective To investigate the predictive value of acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) for nursing workload in emergency intensive care unit (EICU).Methods A retrospective cohort study was conducted. Critical patients except for trauma admitted to EICU of West China Hospital of Sichuan University from June 2012 to July 2016 were enrolled. APACHE Ⅱ score and therapeutic intervention scoring system (TISS-28) score were calculated in each case. The relationship between APACHE Ⅱ score and TISS-28 score was analyzed by correlation analysis and curve estimation.Results A total of 1148 patients were enrolled, including 689 male (60.0%), and age of (56±19) years old, APACHE Ⅱ score was 19 (13, 25), and TISS score was 19 (13, 25). The Spearman correlation coefficient between APACHE Ⅱ score and TISS-28 score was 0.849 (P < 0.001), and that among the linear model quadratic model, composite model, growth model, logarithm model, cubic model and exponential modelR2 were 0.669, 0.710, 0.792, 0.764, 0.765, 0.765, respectively (allP < 0.01), and the most suitable description for relationship between APACHE Ⅱ score and TISS-28 score curve was cubic model. The nursing workload was significantly increased when APACHE Ⅱ score ≥30, and it was decreased when APACHE Ⅱ score < 30.Conclusion APACHE Ⅱ was a useful score for predicting the nursing workload in EICU.

Nonpharmaceutical interventions (NPIs) have been commonly deployed to prevent and control the spread of the coronavirus disease 2019 (COVID-19), resulting in a worldwide decline in influenza prevalence. However, the influenza risk in China warrants cautious assessment. We conducted a cross-sectional, seroepidemiological study in Shandong Province, Northern China in mid-2021. Hemagglutination inhibition was performed to test antibodies against four influenza vaccine strains. A combination of descriptive and meta-analyses was adopted to compare the seroprevalence of influenza antibodies before and during the COVID-19 pandemic. The overall seroprevalence values against A/H1N1pdm09, A/H3N2, B/Victoria, and B/Yamagata were 17.8% (95% CI 16.2%-19.5%), 23.5% (95% CI 21.7%-25.4%), 7.6% (95% CI 6.6%-8.7%), and 15.0 (95% CI 13.5%-16.5%), respectively, in the study period. The overall vaccination rate was extremely low (2.6%). Our results revealed that antibody titers in vaccinated participants were significantly higher than those in unvaccinated individuals (P < 0.001). Notably, the meta-analysis showed that antibodies against A/H1N1pdm09 and A/H3N2 were significantly low in adults after the COVID-19 pandemic (P < 0.01). Increasing vaccination rates and maintaining NPIs are recommended to prevent an elevated influenza risk in China.
