Objective To investigate the effect of acupuncture decompression operation on the quality of life of patients with mild to moderate essential hypertension. Methods 74 cases of mild to moderate essential hypertension were divided into experimental group and control group by random number table, 4 cases were lost. Finally, a total of 70 patients were included in the data analysis. In the control group, 35 cases were given routine drug taking and health guidance, the experimental group of 35 patients increase the treatment of acupuncture decompression operation points on this basis. The two groups of patients were measured with blood pressure before and after intervention, and World Health Organization Quality of Life (WHOQOL-BREF) was used to evaluate the quality of life, and the data were analyzed. Results The scores of physiological and psychological fields in the experimental group were (15.23 ± 2.66) points and (16.68 ± 2.23) points while the control group were (13.98 ± 2.18) points, (15.25 ± 2.52) points, the difference was statistically significant (t=2.305, 2.522, P<0.05). The experimental group of social relations, environmental score were respectively (1.37 ± 2.24) points, (14.16 ± 1.24) points, while the control group were (13.29 ± 2.30) points, (13.56 ± 1.36) points, 2 groups were not statistically significant (t=0.770, 3.063, P > 0.05). The experimental group systolic blood pressure, diastolic blood pressure were (121.43 ± 6.43) mmHg (1 mmHg=0.133 kPa), (71.74 ± 3.88) mmHg, compared with the control group were (128.34±5.72) mmHg, (76.06±4.43) mmHg. The difference was statistically significant (t=-4.753,-4.210, P<0.05). Conclusions acupuncture decompression operation can improve blood pressure in young and middle-aged patients with hypertension, improve the quality of life.

Objective To determine the expression spectrum of microRNA(miRNA)in the lung homogenate of rats with chronic obstructive pulmonary disease(COPD)or healthy rats,to look for differentially expressed miRNA, and to explore their potential role in pathogenesis of COPD. Methods Twenty male Sprague-Dawley(SD)rats were randomly divided into normal control group and COPD model group,with 10 rats in each group. COPD rat models were reproduced by smoke inhalation as well as intratracheal instillation of lipopolysaccharide(LPS). The samples of the lung were harvested,and the histopathological examination of the right lung was carried out to evaluate the degree of lung injury. Total RNAs were isolated from the left lung. The miRNA expressions in lung tissue of rats with COPD or normal rats were determined by miRNA chip eichnology to screen the miRNA with differential expression, and hierarchical clustering analysis was made. The data were analyzed to study the expression difference of miRNAs between the two groups,and to construct the miRNA-Target network. Results Compared with normal control group, 20 miRNA with increased expression were found in COPD model group,the top 10 were miR-30c-2,miR-199a-5p, miR-30a, miR-145, miR-151, miR-674-5p, miR-214, miR-423, miR-28 and miR-181b, and only miR-376b-3p showed down-regulation. Hierarchical clustering analysis showed that significant differences in individual miRNA in lung tissue between rats of two groups were found. However,similar samples could not be gathered well,thus it may give rise to inconsistency during the sample preparation. Many miRNAs had multiple target genes in miRNA-Target network, such as miR-30c-2, miR-145, miR-181b, miR-181a, miR-181d, miR-199. Conclusions The study reveals that there is a variance of miRNAs expression profile in lung homogenates between COPD group and the normal control group of rats,and many miRNAs have multiple target genes,such as miR-30c-2,miR-145,miR-181b,miR-181a,miR-181d,and miR-199. Therefore,the results may be valuable to centain extent for the interpretation of COPD pathogenesis.

Objective To explore a method of establishing a canine model of intracerebral hemorrhage (ICH) by puncturing the main branch of middle cerebral artery (MCA) under ultrasonic guidance and proceed a pilot study of contrast-enhanced ultrasound (CEUS) of ICH.Methods Twelve adult healthy mongrel dogs were enrolled in the experiment.In the condition of bone window,the main branch of MCA was punctured to bleed under the ultrasonic guidance.CEUS of brain was performed every 30 minutes until hematoma formed and another CEUS was performed at 24 hours.Then brains were collected for pathologic examination after dogs were euthanized.Results Eleven of twelve dogs developed ICH successfully that located in the Out edge of basal ganglia,which was confirmed by CEUS and autopsy.One dog died within 6 hours due to intraventricular hemorrhage which was confirmed by autopsy.The hematoma diameters were measured as (22.4 ± 7.1)mm by CEUS before euthanasia and as (21.6 ± 6.9)mm on autopsy.There was no significant difference between the two methods of measurement (t =1.521,P =0.1565).The characteristics of active bleeding and hematoma on ICH were performed in the CEUS imaging.Conclusions A model of dog ICH by puncturing the main branch of MCA under the guidance of ultrasound was established successfully,and it proved to be simple,effective and repeatable.The imaging characteristics of this model are in good accordance with those of ICH in patients.

Objective:To investigate the effects of chitin on atopic dermatitis in an OVA induced AD murine model.Methods:Twenty-eight BALB/c mice were randomly divided into three groups:the normal control group (N)(8),the chitin group(E) (10) and the AD model group(M)(10).The murine model of atopic dermatitis was established through intraperitoneal injection of OVA followed by repeated epicutaneous application of OVA on mice back skin( AD model group).During the set up of AD murine model,mice of the chitin group were given intragastric gavage of 3 mg/d for 4 weeks.At the end of the experiment, the mice were sacrificed and skin lesions were biopsied for histological study.HE and O-toluidine stained paraffin sections were observed under microscope.The spleen cells were cultured and challenged with OVA and chitin,respectively,the supernatant was obtained for cytokine determination.Serum levels of total and OVA-specific IgE and total IgG2a were determined with ELISA.Results:Chitin significantly inhibited skin inflammation induced by OVA.Compared with the AD model group,the thickness of the epidermis and dermis in the chitin group were obviously decreased.The numbers of dermal infiltrated inflammatory cells,eosinophils and mast cells were significantly decreased in the chitin group compared with the AD model group ( P<0.05-0.001 ).The serum level of total IgE and OVA-specific IgE were significantly lower in the chitin group than in the AD model group(P<0.05-0.001),while the serum level of IgG2a in the chitin group was significantly higher than that of the AD model group( P<0.001).The cultured spleen cells of the chitin group produced significantly higher levels of IL-12 and IFN-γ,but lower level of IL-4 compared with those of the AD model group after OVA challenge (P<0.05).Conclusion:Chitin can inhibit the inflammation and decease the seum level of IgE in the murine AD model.The antiallergic effect of chitin might be associated with the induced production of Th1 type cytokines by mice spleen cells.

Objective:To investigate the function of CD 59 in LAT induced T lymphocytes'proliferation and activation.Methods:Transfected LAT-GFP recombinant lentiviral vectors into Jurkat cells and established a fusion-protein stable express cell line ( Jurkat-GFP ).Junket-GFP cells were transfected with pSUPER-siCD59 plasmids by electroporetion or stimulated by anti-CD59 antibody.The cellular locations of CD 59 and LAT were observed under fluorescence microscope with the immunofluorescence cytochem -istry.The cells proliferation were measured by MTT assay.Furthermore,Western blot was used to detect the total and phosphorylation levels of several down-stream proteins after T cell activated .Results: Jurkat-GFP cells successfully transfected with pSUPER-siCD59 plasmids showed lower fluorescence staining.CD59 and LAT distributed uniformly on the cell surface before stimulated with anti-CD59 antibody and formed clusters once upon stimulation.Jurkat-GFP cells stimulated with anti-CD59 antibody showed a higher level of pro-liferation and protein phosphorylation ,compared with the others.Conclusion:CD59 contributed to LAT induced signaling transduction of T lymphocytes ,and stimulated CD59 molecule partly promoted T cell activation.

Objective To evaluate the application value of real-time three-dimensional echocardiography (RT-3D TEE) in nonvalvular atrial fibrillation patients after transcatheter left atrial appendage closure (LAAC) with the Amplatzer Cardiac Plug (ACP).Methods The two-dimensional transesophageal echocardiography (2D TEE) and RT-3D TEE were performed in selected patients to measure the diameter of left atrial appendage ostium and landing zone,to observe left atrial appendage morphology and lobular distribution.These were also performed to guide the whole process of transcatheter LAAC with ACP,which included the atrial septal puncture,sheathing canal cruise,occluder device implantation,and verifying the stability of occluder device and releasing the device.It involved observing ACP occluder morphology,location,stability,surrounding residual shunt,whether influencing the mitral valve and left superior pulmonary vein flow,and pericardial effusion.Results A total of 15 patients (100％) successfully underwent LAAC with the ACP.The maximum diameter of left atrial appendage ostium by 2D-TEE measurement during operation was (20.5 ± 2.9)mm,located at 135°.The diameter of left atrial appendage landing zone was (17.1 ± 2.8) mm,located at 45°;(18.0 ± 4.0) mm,located at 90°;(22.1 ± 4.7)mm,located at 135°,respectively.The left atrial appendage morphology:2 had one leaf and 13 had two leaves or more,including 2 cases of bifoliate short neck shape.In 15 patients,6 cases of cauliflower type,2 cases of wind sock type,3 cases of chicken wing type,2 cases of cactus type and 2 cases of complex type.The proximal left atrial appendage morphology:3 cases of boot type,2 cases of wide mouth type,6 cases of narrow mouth type,2 cases of straight tube type,and 2 cases of bifoliate short neck type.There was no obvious residual shunt in all the patients at immediately post-operation.Conclusions In the transcatheter LAAC with the ACP,RT-3D TEE has important application value in the preoperative selection of patients,the choice of appropriate occluder,guidance of full-process monitoring during operation,the postoperative effect evaluation and so on.

BACKGROUNDThe identification of vulnerable plaques before rupture is an important clinical goal. The purpose of the present study was to assess the difference in plaque composition among patients with acute coronary syndrome (ACS) and stable coronary artery disease (SCAD) by intravascular ultrasound virtual histologic analysis.

METHODSOne hundred and thirty-nine patients were divided into ACS group and SCAD group according to clinical presentation. A total of 229 de novo lesions with >50% stenosis in native coronary arteries with diameters >2.5 mm were studied with intravascular ultrasonography. Geometric and compositional data were obtained using intravascular ultrasound virtual histology software.

RESULTSThere were no significant differences in overall lesions for fibrous ((52.0+/-11.9)% vs (54.3+/-8.5)%, P>0.05), fibrolipidic ((12.3+/-10.1)% vs (13.8+/-9.5)%, P > 0.05), calcium ((14.0+/-9.1)% vs (19.3+/-13.1)%, P>0.05), or necrotic core ((22.0+/-11.1)% vs (19.7 +/- 5.4)%, P > 0.05) percentages in ACS and SCAD patients, respectively. There were also no significant differences in culprit lesions for fibrous ((46.4+/-12.0)% vs (53.6+/-8.8)%, P>0.05), fibrolipidic ((9.1+/-9.0)% vs (12.9+/-9.7)%, P>0.05), calcium ((16.6+/-9.7)% vs (21.8+/-26.3)%, P>0.05), or necrotic core ((28.0+/-12.6)% vs (20.6+/-5.2)%, P>0.05) percentages in ACS and SCAD patients, respectively. High density lipoprotein-cholesterol levels >1.04 mmol/L were associated with more fibrolipidic ((14.5+/-10.4)% vs (7.1+/-6.5)%, P<0.05) and less necrotic core ((20.6+/-9.7)% vs (27.9+/-12.6)%, P<0.05) percentages in the cohort with ACS.

CONCLUSIONSIn this study, coronary plaque composition assessed by intravascular ultrasound virtual histologic analysis was not significantly different between ACS and SCAD patients. The anatomic relationship of the specific plaque components to the lumen of the vessel was more important than the quantitative information of plaque composition for plaque stability.
