ABSTRACT
OBJECTIVE@#To systematically evaluate the efficacy and safety of Tanreqing Injection (, TRQI) combined with conventional treatment on clinical outcomes in the treatment of patients with influenza.@*METHODS@#The electronic databases searched were Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), MEDLINE (PubMed), EMbase (OvidSP), Chinese Bio-medical Literature and Retrieval System (Sinomed), China National Knowledge Infrastructure Database (CNKI), China Science and Technology Journal Database (VIP) and WanFang Data Knowledge Service Platform, and we checked the reference sections of the retrieved articles as well. The search was performed in October 2018, and we used the randomized controlled trials (RCTs) that corresponded to the new diagnostic criteria for influenza. Two review authors independently screened the internalized articles in accordance with the Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) statement checklist. We evaluated the quality of the articles and extracted the data from the studies using the Revmen5.3 software.@*RESULTS@#We included 12 RCTs of over 882 cases in this meta-analysis. Compared to conventional treatment, TRQI combined with conventional treatment could increase the total effective rate [9 RCTs, n=648, odds ratio (OR): 4.92, 95% confidence interval (CI): 2.94, 8.24, P<0.0001, random effects model], decrease the average time for fever clearance [7 RCTs, n=564, mean difference (MD): -1.08, 95% CI: -1.68, -0.48, P=0.0004, random effects model] and decrease the time for resolution of cough (5 RCTs, n=362, MD: -1.76, 95% CI: -2.63, -0.90, P<0.0001, random effects model).@*CONCLUSION@#Based on this meta-analysis of RCTs, TRQI combined with conventional treatment had a statistically significant benefit in increasing the total effective treatment rate and reducing the time for fever clearance as well as time for resolution of cough.
ABSTRACT
Objective@#To analyze the influence of malnutrition in the elderly patients with acute coronary syndrome on related factors and short-term prognosis.@*Methods@#415 elderly patients with acute coronary syndrome were selected.Comprehensive geriatric assessment was used to investigate the risk of acute coronary syndrome by examining coexisting diseases and using the NRS2000 score.The mortality and emergency visits were followed up.@*Results@#The patients were divided into two groups according to NRS2000 score: malnutrition group (n=179) and non-malnutrition group (n=236).

ABSTRACT
Objective To investigate the relationship between heart rate variability and type 2 diabetes mellitus(T2DM)in Kirgiz and Han,to understand the differences between ethnic groups,at the same time to provide effective method for type 2 diabetic autonomic neuropathy.Methods 24 -h Holter recording was performed in 1 46 individuals.75 cases of T2DMconfirmed by glycolated hemoglobin(HbA1 c)were selected as observation group, Kirgiz 40 people,Han 35 people.While 71 subjects without T2DM were chosen as control group,Kirgiz 34 people, Han 37 people.The HRV indices,including standard deviation (SD)for the time between normal -to -normal complexes in the entire 24 h electrocardiographic recording(SDNN),the average of SD for the time between normal -to -normal intervals for each 5 min period(SDNN5),the percentage of adjacent RR intervals 50 ms apart(PNN50), normal RR intervals divided by RR intervals derived from the triangle index(TRIA),SD of the average normal -to -normal intervals for each 5 min period (SDANN)and root -mean square of differences of successive RR intervals (RMSSD)were compared between these groups.Results There were no significant differences in age,gender, education level and smoking between Kirgiz and Han patients.The differences were statistically significant in SDNN, SDNN5,PNN50,SDANN,TRIA(t =3.392,P =0.001 ;t =3.652,P =0.001 ;t =3.826,P =0.001 ;t =3.235,P =0.002;t =2.378,P =0.02)between patients with or without T2DMin Kirgiz population.In contrast,the mean square root of SDNN,SDNN5,PNN50,TRIA,RMSSD(t =3.498,P =0.001 ;t =3.41 4,P =0.001 ;t =2.1 05,P =0.039;t =2.1 02,P =0.039;t =3.41 3,P =0.001 )were statistically significant in Han population between T2DM patients and nondiabetic patients.There was no deference between Han and Kirgiz patients without T2DM in HRV,whereas the TRIA(t =2.887,P =0.005 )had significant difference in T2DM patients between Han and Kirgiz population. Conclusion The HRV is significantly reduced in the T2DMpatients,especially the Kirgiz.The HRV analysis using 24h Holter is a noninvasive technology to detect the T2DM.
ABSTRACT
Plague is a virulent infectious disease in China. In this study, '3S' technology was used to perform spatial autocorrelation analysis and spatial interpolation analysis for Spermophilus dauricus (S. Dauricus, a species of ground squirrel) captured in Manchuria City in 2015. The results were visually inspected. During the two-month (May to July) plague surveillance in 2015, 198 S. dauricus individuals were captured in the study area in Manchuria City (48 monitoring areas) by using a day-by-day catching method. Spatial autocorrelation was conducted using the ArcGIS software, and the following significantly different results were obtained: Moran's I=0.228472, Z-score=2.889126, and P<0.05. Thus, a spatial aggregation was observed. In 2015, the distribution of S. dauricus diminished from west to east and from north to south of Manchuria. Geo Detector software was used to analyze the habitat factors affecting the spatial distribution of S. dauricus. This highly clustered species mainly exists in suburban communities, construction sites, and areas surrounding factories. In future studies, plague surveillances should be performed in areas around Manchuria and Zhalainuoer.

ABSTRACT
<p><b>OBJECTIVE</b>To study the expression of Rho/Rho kinase of cardiac muscle in heart failure rats caused by pressure overload and the effects of fasudil on heart failure.</p><p><b>METHODS</b>The heart failure models were successfully induced by coarctation of ascending aorta after 20 weeks in this study. Thirty female Wistar operated rats were divided randomly into three groups (n = 10) for 4 week treatment. (1) Sham operation group: normal saline, 0.1 ml, i.p,Bid. (2) Heart failure group: normal saline, 0.1 ml,i.p,Bid. (3) Fasudil group: fasudil 5 mg/kg, i.p, Bid. The hemodynamic parameters, the ratio of LV weight to body weight, the expressions of RhoA and Rho kinase mRNA, and the concentration of calcium ion same as [Ca(2+)](i) were investigated in the three groups.</p><p><b>RESULTS</b>Hemodynamic parameters were significantly changed in heart failure group than those in sham operation group, such as left ventricular diastolic end pressure increased [(13.00 +/- 0.30) mm Hg vs (3.78 +/- 0.31) mm Hg, P < 0.01], left ventricular systolic pressure decreased [(97.20 +/- 7.21) mm Hg vs (129.45 +/- 7.52) mm Hg, P < 0.01]. Those results could be significantly changed by use of fasudil, P < 0.01. The ratio of LV weight to body weight was significantly increased in heart failure group than that in sham operation group [(4.77 +/- 0.08) mg/g vs (2.51 +/- 0.12) mg/g, P < 0.01]. Fasudil could significantly decrease the ratio of LV weight to body weight compared with that in heart failure group [(4.05 +/- 0.08) mg/g vs (4.77 +/- 0.08) mg/g, P < 0.01]. Cardiac muscle RhoA, Rho kinase mRNA level and [Ca(2+)](i) were higher in heart failure group than those in sham operation group [Ca(2+)](i) (475.93 +/- 28.22) nmol/L vs (79.25 +/- 3.33) nmol/L, P < 0.01. Compared with those in heart failure group, the expressions of RhoA, Rho kinase mRNA level decreased significantly, P < 0.01, and the levels of cardiomyocyte [Ca(2+)](i) had no change in fasudil group [(462.78 +/- 16.72) nmol/L vs (475.93 +/- 28.22) nmol/L, P > 0.05].</p><p><b>CONCLUSIONS</b>These results indicated that heart failure was probably related to activating of RhoA, Rho kinase. Fasudil may contribute to the observed beneficial effects on heart failure such as the decrease of RhoA, Rho kinase mRNA expression and not increase of [Ca(2+)](i) level. Rho/Rho kinase may be a novel, potent signaling of heart failure.</p>
