ABSTRACT

Objective To investigate the expression profile of long non - coding RNAs(lncRNAs) in acute kidney injury (AKI) rats upon astragaloside IV(AS - IV) treatment. Methods Eight male SD rats were selected and randomly divided into two groups. AKI model group(group 1):4 rats were subjected to ischemia - reperfusion(I/ R);AS - Ⅳ pretreatment group (group 2):4 rats were orally administered AS - Ⅳ for 7 days prior to I/ R. Renal tissues were collected after I/ R treatment of 24h,total RNA was extracted from renal tissues and tested for quality. Sequencing experiments were carried out after being qualified. The threshold set for up - and down - regulated genes was a fold change(group1 / group2)≥2 and P≤0. 05. Afterwards,GO analysis and KEGG analysis were used to determine the roles that these differentially expressed mRNAs played in these GO terms or pathways. Results Two hundred and thirty - two lncRNAs were differentially expressed(127 lncRNAs were up - regulated and 105 lncRNAs were down -regulated). Three hundred and forty - one mRNAs were differentially expressed(178 mRNAs were up - regulated and 163 mRNAs were down - regulated). GO analysis indicated that differentially expressed mRNAs were mainly involved in biological processes such as nucleosome assembly,chromatin assembly,nucleosome organization,chromatin assembly or disassembly and DNA conformation change. GO analysis indicated that differentially expressed mRNAs were mainly involved in cellular components such as nucleosome,protein - DNA complex,nuclear chromatin,chromatin and nuclear nucleosome. GO analysis indicated that differentially expressed mRNAs were mainly involved in molecular functions such as protein heterodimerization activity,protein dimerization activity,DNA binding,nucleic acid binding. Signal pathway analysis indicated that lncRNAs and mRNAs were involved in systemic lupus erythematosus,alcoholism and viral carcinogenesis. Conclusion LncRNAs expression differed significantly in renal tissues of AKI model group and AS - Ⅳ preconditioning group. Study of the biological functions and pathways of these lncRNAs indicated that they may be involved in the mechanism of AS - Ⅳ ameliorated ischemic acute renal injury.

ABSTRACT

Objective:To observe the efficacy of benefiting Qi for warming Yang and activating blood circulation for inducing diu-resis method in the treatment of patients with chronic heart failure( CHF) and its effect on the expression of circulating miRNAs ( miR-423-5p, miR-210-3p). Methods:Totally 80 CHF patients were randomly divided into two groups,the control group with 40 patients was treated with the conventional anti-heart failure therapy, and the treatment group with 40 patients was treated with benefiting Qi for warming Yang and activating blood circulation for inducing diuresis decoction on the basis of the control group, and the treatment course was 2 weeks. The clinical efficacy and syndrome integral of traditional Chinese medicine ( TCM) were evaluated. Left ventricular ejec-tion fraction ( LVEF) and left ventricular end diastolic diameter( LVEDD) were measured by echocardiography;the plasma expression levels of circulating miRNAs(miR-423-5p, miR-210-3p) were measured by real-time PCR in the two groups before and after the treat-ment. The adverse drug reactions were observed as well. Results:The total clinical effective rate of the treatment group was significant-ly higher than that of the control group (87. 50% vs 65. 00%, P <0. 05); the syndrome integral of TCM, indices of LVEF and LVEDD and the expression of circulating miRNAs were improved in both groups(P<0. 05);the total clinical effective rate, syndrome integral of TCM, indices of LVEF and LVEDD and the expression of circulating miR-423-5p of the treatment group were better than those of the control group(P<0. 05); there was no significant difference in adverse drug reactions between the groups (P>0. 05). Conclusion:The benefiting Qi for warming Yang and activating blood circulation for inducing diuresis method can improve the clinical effects in the treatment of CHF, and improve the expression of circulating miRNAs.

ABSTRACT

Objective To analyze the MSCT manifestations of septic pulmonary embolism(SPE)to explore the diagnosis value of MSCT.Methods The MSCT findings of eight patients with SPE were analyzed retrospectively.Results ① Of all 177 lesions,84 lesions located in both upper lobes,25 lesions located in right middle lobe and 68 lesions located in both lower lobes.② There were 106 nodules and 44 wedge shaped opacities in all the 8 cases,of which the 88 nodules (83.0%)and all of the wedge shaped opacities located in sub-pleural zones of the lung and the 18 nodules (1 7.0%)located in the inner and middle lung fields.In 6 cases,the 26 nodules (24.5%)and the 1 6 wedge shaped lesions (38.1%)had “feeding vessels”.③ There were 27 patchy shadows in 6 patients,of which 12 patchy shadows (44.4%)had air bronchogram.④ There were 18 cavities in 6 patients,of which 14 cavities (13.2%)located in nodules and 4 cavities (9.1%) in the wedge shaped lesions.There were 8 cysts in 4 patients,of which 6 cysts located in nodules (5.7%)and 2 cysts in the wedge shaped lesions (4.5%).⑤ The nodules and the wedge shaped lesions were enhanced slightly.⑥ Pleural effusion and pericardial effusion were found in 4 and 3 patients,repectively.⑦ Of 6 patients the follow-up MSCT scan in a short period showed the disease progressions. Conclusion SPE has characteristic manifestations in MSCT,and MSCT can provide valuable information for the diagnosis of SPE.

ABSTRACT

Objective:To explore the hemodynamic changes in aged patients with essential hypertension (EH). Methods: Our research included 2 groups, EH group, n=180 patients and Control group, n=100 subjects without cardiovascular diseases. The relevant indexes were recorded and compared by BioZ.com noninvasive hemodynamic monitor between 2 groups. Results: With statistic processing, the cardiac output/index (CO/CI), cardiac index, thoracic lfuid content (TFC), systemic vascular resistance/index (SVR/SVRI) were signiifcantly different between EH group and Control group, all P Conclusion: The hemodynamic changes exist at certain degree indicating the potential injury of cardiac function in aged EH patients, such changes might be helpful for clinical diagnosis and treatment in EH patients.

ABSTRACT

OBJECTIVE@#To evaluate correlation between and agreement in light transmittance aggregation (LTA) and thromboelastography (TEG) in laboratory diagnosing aspirin resistance (AR), and to determine the prevalence of AR in old patients.@*METHODS@#Patients in the Wanshoulu District of Beijing with ischemic atherothrombotic diseases were recruited. Inclusion criteria were age ≥ 65 years, and having received regular aspirin therapy (75-100 mg daily) for at least 4 weeks. On the basis of LTA assay, the definition of AR was taken as aggregation of ≥ 20% with AA (arachidonic acid), and of ≥ 70% with ADP (adenosine diphosphate). Aspirin-sensitivity was indicated by the absence of either of these criteria; aspirinsensitivity was indicated as both criteria being met. The definition of AR by TEG is ≥ 50% via AA-induced whole blood aggregation.@*RESULTS@#There were 13.69% prevalence of aspirin resistance for LTA using AA as the agonist, 30.16% prevalence of aspirin resistance for LTA using ADP as the agonist, and 23.67% prevalence of aspirin resistance for TEG using AA as the agonist. Results from these tests showed poor agreement (Kappa<0.4). However, by the method of LTA using AA and ADP as the agonists, prevalence of AR was 8.35%. By methods of AA-induced LTA and AA-induced TEG, prevalence of AR was 8.82%. Results from these two latter methods showed good agreement (Kappa = 0.793).@*CONCLUSION@#Combined methods, as described here, have good correlation and agreement in the assays of AR, and the results with them represent a realistic measure of the prevalence of AR. Prevalence of AR of elderly patients from Wanshoulu district of Beijing is about 9%.
