MicroRNAs (miRNAs) are small noncoding regulatory RNAs ranging in size from 17 to 25 nucleotides which participate many physiological and pathological processes.MicroRNA could also stably exist in peripheral blood,and the detection of circulating microRNA is of great significance for disease diagnosis and prognosis.As so far,there is no unified method and standard for detection of microRNA,which is the major reason for discrepant results between different studies.However,circulating microRNA,as a new disease detection biomarker,has stable properties,convenient detection and high accuracy features,so it till has an important potential value in clinical applications.

Objective: To explore the effects of different drying methods on the quality of medicinal materials, and screen out the optimal drying process of Centella asiatica. Methods: The whole fresh grass of C. asiatica were dried by hot air, drying in the sun, drying in the sun and hot air combined, drying in the shade, microwave and vacuum respectively. Meanwhile, the drying time and rate were determined. The characters, identification, inspection, and leachable content of C. asiatica were analyzed by the method of pharmacopoeia. The content of asiaticoside, madecassoside, asiatic acid, madecassic acid, kaempferol-3-O-tutinoside, kaempferol, and quercetin were detected by HPLC analysis; The weighted scoring method was used to sort the comprehensive evaluation of multiple indexes. Results: Different drying methods consume different time, among which drying in the sun, shade and drying at 50 ℃ for more than 100 h, and the average drying rate was 24.83%. The effects of different drying methods on the properties of medicinal materials are mainly reflected in color and odor, among which 50-70 ℃ hot air drying had a better color, which was light green, and the odor of hot air drying and microwave drying at 80 ℃ and 85 ℃ also changed significantly. Although there were some differences in moisture and ash content, both of them met the pharmacopoeia standards. The drying method also had certain effects on the leachable, the maximum was 45.70%, and the minimum content of dry extract was 29.67%. The highest content of the total active ingredient was determined by HPLC using the method of drying in the shade, which was 83.032 mg/g, and the lowest was is 75 ℃ hot air drying, which was 40.982 mg/g. The highest total content of madecassoside and asiaticoside was 80 ℃ hot air drying, and the lowest was 75 ℃ hot air drying. Weighted score in the top three of line was 70 ℃, dried at 50 ℃ after drying in the sun, hot air drying at 50 ℃, and 85 ℃ hot air drying ranked the bottom. Conclusion: In summary, the suitable drying method for the production area of C. asiatica was 70 ℃ hot air drying.

Objective To evaluate the clinical practicality of two different D-dimer assays by studying the correlation of the testing results by two different D-dimer reagents with fibrin degradation products (FDP)result values and analyzing the Clinical alignment.Methods A representative cross-sectional study of 762 clinical patients’plasma specimens were taken to measure the results of D-dimer and FDP by using Sysmex CA-1500 automated coagulation analyzer,D-DIMER detection rea-gent respectively Siemens Innovance D-DIMER and Dade Behring D-DIMER Plus reagents.Then rating frequency analysis and Spearman correlation test were applied to analyze the correlation of measurement results.Results Overall,to the same patient,the correlation of D-dimer tested by Siemens Innovance D-DIMER Reagent with FDP level was significant positive (r= 0.954,P<0.01),better than that tested by Siemens DD Plus Reagent (r=0.885,P<0.01);and this correlation had an increasing trend when D-dimer level raised.When D-dimer level > 5 mg/L FEU,the correlation was the best (P<0.01). And by calculating the amount of positive FDP (FDP>5μg/ml)and FDP positive rate in both different cases when D-dimer results was also positive,FDP positive rate in Innovance D-DIMER Reagent group (about 65.76%)was lower than DD Plus Reagent group,it indicated that D-dimer results tested by Innovance D-DIMER Reagent could raise before FDP reacted,so D-dimer had a higher sensitivity than FDP.Conclusion It can provide a more precise clinical diagnosis and treatment infor-mation when using Siemens Innovance D-DIMER Reagent to detect D-dimer values and combined FDP values at the same time.

Objective To explore the value of somatostatin receptor scintigraphy(SRS) in evaluating the immune activity of orbital inflammatory pseudotumor associated with systemic vasculitis.Methods Twenty-five patients with orbital inflammatory pseudotumor associated with systemic vasculitis (10 males,15 females,average age:(51.2± 14.2) years) underwent SRS.The uptake ratio (UR) of orbital inflammatory pseudotumor was obtained.(1) Patients were divided into group A (with immune activity) and group B (without immune activity) according to Birmingham vasculitis activity score (BVAS).The difference of UR between the 2 groups was compared by two-sample t test.The difference of UR before and after treatment in 12 patients was also compared.(2) Based on the results by BVAS,ROC curve was used to obtain the cut-off value of UR,as well as the diagnostic efficiency and Youden index.The consistency between SRS and BVAS was calculated.(3)Patients were divided into two groups according to the cut-off value of UR and the prognosis difference between them was compared by Fisher exact test.(4)The expression of SSTR2 and SSTR5 was observed by immunohistochemistry.Results (1) UR in group A was significantly higher than that in group B (2.09±0.44 vs 1.32±0.46,t =5.94,P＜0.01).After glucocorticoids treatment,the UR in group A reduced significantly (t=4.07,P＜0.01),but not in group B (t=1.76,P＞0.05).(2)ROC curve analysis identified UR cut-off value as 1.66,with the sensitivity of 87.5％,specificity of 95.7％,positive predictive value of 95.2％,negative predictive value of 88.0％,accuracy of 91.3％ and Youden index of 83.2％.The consistency between SRS and BVAS was strong (Kappa =0.840).(3) The prognosis was significantly different between patients with UR≥ 1.66 and UR＜1.66 (P＜0.05).(4) The immunohistochemical results revealed high expression of SSTR2 and SSTR5 in inflammatory cells in patients with immune activity.Conclusion SRS has potential value in evaluating the immune activity of orbital inflammatory pseudotumor associated with systemic vasculitis.
