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 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 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.
