OBJECTIVETo evaluate the clinical effectiveness of Yiqi Huoxue Tongyang Xiezhuo Recipe (YHTXR, capable of supplementing qi, activating blood, warming yang, and discharge turbidity) in treating coronary atherosclerotic heart disease (CAHD). and chronic heart failure (CHF) with carotid plaque patients, and to explore new ways of Chinese medicine (CM).

METHODSTotally 69 CAHD-CHF patients of qi deficiency phlegm stasis syndrome (QDPSS) with carotid plaque were recruited in this study using parallel cohort method. They were assigned to the treatment group (35 cases) and the control group (34 cases). Patients in the control group received routine treatment of Western medicine, while those in the treatment group were additionally treated with YHTXR (twice daily). The therapeutic course for all was three months. Cardiac function levels, echocardiography, carotid plaque, blood lipids and safety indicators were observed before and after treatment.

RESULTSAfter treatment the improvement of cardiac function levels was better in the treatment group than in the control group (P < 0.05). Decreased LDL-C levels were higher in the treatment group than in the control group (P < 0.01). There was statistical difference in left ventricular ejection fraction (LVEF), carotid intima-media thickness (IMT), LDL-C, TC, TG in the treatment group between before and after treatment (P < 0.05). LDL-C and TG also decreased in the control group after treatment (P <0.05). There was no significant difference in the left ventricular ejection fraction, carotid IMT, or TC in the control group between before and after treatment (P > 0.05). There was no significant difference in stroke volume, left ventricular end-diastolic diameter, the area of carotid artery plaque, or HDL-C in the two groups between before and after treatment (P > 0.05).

Objective:To analyze the expression of circular RNA (circRNA) in peripheral blood mononuclear cells (PBMCs) of patients with gout and to explore the possible mechanism of circRNA in the pathogenesis of gout.Methods:Peripheral blood samples of 24 patients with acute gout (AG), 24 patients with intermittent gout (IG) and 24 healthy control subjects (HC) were collected. Three cases of AG, IG, and HC were randomly selected, and the differentially expressed circRNA in PBMCs was screened by human circNA microarrays. The 6 circRNAs with large differences between the two comparison groups were selected, and the relative expression levels of 6 circRNAs in all the collected 72 PBMCs of the study subjects were detected by real-time fluorescent quantitative polymerase chain reaction (RT-qPCR). The significantly differentially ex-pressed circRNA (fold change>1.5, P<0.05) was analyzed by GO analysis, Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis, and its interaction with microRNA (miRNA) was predicted. The median (interquartile range) was used to describe the data, and the Mann-Whitney U test was used for comparison between groups. Results:(1) The microarray analysis results showed that compared with the HC group, the AG group and the IG group had 116 and 41 significantly differently expressed circRNAs, respectively; com-pared with the IG group, the AG group had 105 significantly differently expressed circRNAs. (2) Among the 6 circRNAs verified by PT-qPCR, the expression trends of 5 were consistent with the microarray results. The expression of hsa_circRNA_105034 in the AG group [5.17(4.60)] was statistically significantly different com-pared to the IG [1.68(2.39)] and HC [0.90(0.73)] groups (AG vs IG: Z=-4.413, P<0.01; AG vs HC Z=-5.052, P<0.01). (3) Bioinformatics analysis: ① GO analysis found that differential circRNA swere mainly involved in DNA transcriptional regulation, positive cell regulation and protein modification, etc. ② KEGG pathway analysis revealed that differential circRNA might be involved in the immune response mediated by the mitogen-activated protein kinase signaling pathway. ③ CircRNA might affect its inflammatory response by targeting molecules such as miRNA-146a, miRNA-302b and miRNA-23a. Conclusion:There are differentially expressed circRNAs in PBMCs of patients with gout, which may be closely related to the occurrence and development of gout.

Objective:To screen for circle RNA (circRNA) differentially expressed in peripheral blood mononuclear cells (PBMCs) of patients with ankylosing spondylitis (AS), and to analyze its expression profile to explore the role of circRNAs in the pathogenesis of AS.Methods:CircRNA microarray chip technology was used to detect the expression of circRNAs in PBMCs of 3 patients with active AS, 3 patients with stable AS and 3 healthy controls (HC), and then screening for differentially expressed circRNAs by fold change (FC) and P value. Then differentially expressed circRNAs among the circRNAs with the highest differential expression were selected randomly to verify the chip results by real-time fluorescence quantitative polymerase chain reaction (qPCR); Differentially expressed circRNAs were subjected to Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and microRNA (miRNA) target prediction software was used to predict the circRNA/miRNA interaction relationship. Finally, the data were statistically analyzed by t test and Mann-Whitney U test. Results:① Chip text results showed that there were 800 circRNAs with significantly different expression (FC>1.5, P<0.05) in active AS than HC, of which 466 were up-regulated and 334 were down-regulated; the stable AS had a total of 1 149 significantly differentially expressed when compared with the HC (FC>1.5, P<0.05) circRNAs, of which 589 were up-regulated and 560 were down-regulated. 233 circRNAs were significantly differentially expressed (FC>1.5, P<0.05) between active AS and stable AS, of which 145 were up-regulated and 88 were down-regulated. ②The RT-qPCR verification results suggested that the expression trends of the four differentially expressed circRNAs were consistent with the results of the chip. ③ GO analysis results suggested that these differentially expressed circRNAs were mainly involved in nonsense-mediated mRNA decay, Rho GTPase binding and other processes. The analysis showed that the KEGG pathway were enriched in Th17 cell differentiation and chemokine signaling pathways. The results of miRNA target prediction software analysis suggested that differentially expressed circRNAs might play a role by targeting miR-650, let-7b-5p and other miRNAs. Conclusion:Compared with HC group, there were differentially expressed circRNAs in Peripheral Blood Mononuclear Cells (PBMCs) of AS patients, The results of this study suggest that these circRNAs may be involved in the pathogenesis of AS.

OBJECTIVETo explore effects of 650 nm laser and moxibustion pretreatment on visceral traction pain (VTP) and its mechanism.

METHODSForty male SD rats were randomly devided into a sham operation group (group A), a VTP group (group B), a 650 nm laser pretreatment group (group C), a moxibustion pretreatment group (group D). Rats in group A and group B were not treated except sham operation or VTP model. In group C and D, the VTP models were produced immediate after 650 nm laser irradiation or moxibustion at "Zusanli" (ST 36), respectively. The changes of pain score and systolic pressure were investigated and the activity of AChE, the content of SP and leu-enkephaline (LEK), and the positive index of c-Fos protein and glial fibrillary acidic protein (GFAP) were detected by biochemistry, radio-immunity method and immunohistochemistry, respectively.

RESULTSCompared with group A, the pain score, systolic pressure, the activity of AChE, the content of SP, and the positive index of c-Fos protein and GFAP of group B increased significantly (all P < 0.05); compared with group B, the pain score, AChE activity, the content of SP and the positive index of c-Fos protein and GFAP of both group C and group D decreased significantly (all P < 0.05); compared with group B, the content of LEK increased and systolic pressure decreased significantly in group C (both P < 0.05).

CONCLUSIONBoth 650 nm laser and moxibustion pretreatment can inhibit VTP and the mechanism may be related to reducing the activity of AChE and the content of SP, and increasing the activity of LEK and decreasing the expression of c-Fos protein and GFAP.

AIM: To investigate therapeutic efficiency of amniotic extraction on dry eye in rabbit model induced by topical benzalkonium chloride (BAC).
METHODS: Totally 26 rabbits (26 right eyes) with dry eye model were studied and divided into two groups:group A (control group with PBS eye drops, n = 13) and group B ( amniotic extraction group, n = 13). Another two rabbits were chosen as normal control. The SchirmerⅠ tests ( S Ⅰ t) and corneal fluorescein staining ( FL) were made, and the tear total protein content, amylase activity, lactoferrin, lysozyme contents, goblet cell density were performed in two groups before treatment and 1, 2, 4 and 8 wk after treatment.
RESULTS: There were significant differences in SIT, FL scores, lysozyme activity and goblet cell density among different groups at different time points (P<0. 05). But, there was no significant differences in SⅠt, FL scores, lysozyme activity and goblet cell density between two groups before treatment (P>0. 05). After 8wks' treatment with PBS, the mean differences of the group A showed great changes in SⅠt, lysozyme and goblet cell density compared with those before treatment ( P < 0. 05); but there was no significant differences in FL scores compared with those before treatment (P>0. 05). As for group B, 8wks after treatment, there were statistical changes in SⅠt, FL, lysozyme (P<0. 05); but there was no significant differences in goblet cell density compared with those before treatment ( P > 0. 05). It was evident that statistical differences were observed in S Ⅰ t, FL scores, lysozyme activity and goblet cell density between two groups at each time point (P<0. 05). However, there were no significant differences in total protein, lactoferrin, amylase activity at different time points (P>0. 05). Meanwhile there was no significant differences in total protein, lactoferrin, amylase activity between two groups before treatment ( P > 0. 05 ). But there were significant differences in total protein, lactoferrin, amylase activity between two groups after 4 and 8 wks'treatment (P<0. 05).
CONCLUSION: Amniotic extraction has significant therapeutic effect on the dry eye in rabbit model.
