OBJECTIVETo observe the immediate antihypertensive effect of guasha combined with bleeding therapy for mild (grade I) hypertension.

METHODSThirty patients with mild (grade I) hypertension and 30 cases with normal blood pressure were compared. Areas and acupoints in governor vessel, meridian of foot-taiyang, meridian of hand-yangming and meridian of foot-yangming were scraped for 3 times, which was followed by bleeding therapy. The blood pressures after each guasha and bleeding therapy were recorded as well as the skin temperature in Dazhui (GV 14) after each guasha. The treatment was given once a week and totally 4 treatments were given.

RESULTSThere were significant antihypertensive effects after the first guasha, the second guasha and the third guasha and bleeding therapy (all P<0.01), in which guasha combined with bleeding therapy had the most significant antihypertensive effect (P<0.01). The skin temperature in Dazhui (GV 14) was obviously increased after three times of guasha (all P<0.01).

CONCLUSIONGuasha or combined with bleeding therapy has better antihypertensive effect for mild hypertension, which is likely to be related with warming stimulation on meridians and acupoints.

The image guided radio therapy (IGRT) Imaging System based on cone-beam computer tomography (CBCT) can reach the goal of improving the accuracy of the radiotherapy. However, because the clinical registration between CBCT images and Planning CT images is carried out manually, it inevitably reduces radiation positioning accuracy to some extent. To tackle the problem, we proposed a new feature vector selection method for the CBCT image elastic registration in the framework of hierarchical attribute matching mechanism for elastic registration (HAMMER) algorithm. We analyzed the characteristics of HAMMER algorithm and used Canny operator which has a better edge detection and positioning performance to replace the noise-sensitive gradient amplitude. Therefore, we used a new attribute vector, which consisted of the intensity, Laplacian of the Gaussian and Canny operator, to ex tract the image feature points in CBCT and planning CT images. We also presented an adaptive feature-point selection method and the choice criteria of attribute vector weights. Experimental results showed that the new feature vector effectively avoided the noise interference resulted from scattering lines in CBCT images to improve registration accuracy, and it also decreased the required feature point numbers and reduced the computation redundancy, so that it provided a new approach for the clinical elastic registration of CBCT and Planning CT rapidly and accurately.

Objective:To investigate the effects of endostatin on Ang-2/Tie-2 system in ectopic lesion.Methods:Thirty mice of endometriosis model (EM) were established by peritoneum planted.After 1 week of transplantation,model mice were randomly divided into three groups including rAAV2-hEndostatin-EGFP group (n=20),rAAV2-EGFP group (n=20)and PBS control group (n=20).The histology changes were examined in the three groups.The expressions of Ang-2 and Tie-2 Were examined by immunohistochemistry.Results:The EM model mice were established suecessfully.The gland proliferation was obvious in the two control groups.The mesenchymal blood vessel was rich.But there were gland atrophy and blood vessel reducing in endostatin group.There were expressions of Ang-2 and Tie-2 in the cytoplasm of endothelium,epithelial glands and stroma.The positive rate of Ang-2 expression was 40%in endostatin group,much lower than that in other two groups(75%and 80%,P＜0.05).The positive rate of Tie-2 expression was 45%in endostatin group,which was also lower than that in other two groups(80%and 85%,P＜O.05).Conclusion:Endostatin can effectively interfere angiogenesis process of Ang-2/Tie-2,which lays the foundation for clinical therapy by anti-angiogenesis.

Objective To evaluate the accuracy and sensitivity of three techniques in the diagnosis of renal diseases following multiple myeloma. Methods 41 serum samples from the kidney-damaged patients with multiple myeloma and 36 from the control group with general renal diseases were detected by quantitative analysis of immunoglobulins, serum protein electrophoresis and serum Immunofixation Electrophoresis. The accuracy and sensitivity of the three techniques were analysed by Two-way ANOVA and Multiple Comparisons of the check-out rate of monoclonal immunoglobulin. Results No monoclonal components were checked out by quantitative analysis of immunoglobulins. The checkout rate of IgG and IgM myelomas were 100% by serum protein electrophoresis, which had application limit on other types of myelomas. Whereas all secretarial myelomas could be diagnosed and typied by Immunofixation Electrophoresis, the sensitivity and accuracy was 100%, there was no false positive in the control group. Comparing with quantitative analysis of immunoglobulins and serum protein electrophoresis, serum Immunofixation electrophoresis had higher sensitivity and accuracy in diagnosis of renal diseases following multiple myeloma ( P

Objective To investigate the effects of diclofenac sodium suppositories on emergence agitation after sevoflurane maintenance in children undergoing adenotonsilleetomy. Methods Forty-five patients selected for adenotonsillectomy were randomly divided into three groups (n=15). Patients in group 1 were given diclofenac sodium suppositories 12.5 mg right after intubation, those in group 2 were given diclofenac sodium suppositories 12.5 mg immediately after operation, while those in control group were not treated with diclofenac sodium suppositories before or after operation. The extubation time and time spent in post-anesthctic ICU (PACU) were recorded, the modified Aldrete score and pain score were assessed after entrance into PACU, and pediatric anesthesia emergence delirium (PAED) scale was administered 10, 20 and 30 rain after entrance into PACU. Results There was no significant difference in extubation time and time spent in PACU among three groups(P>0.05). Ten minutes after entrance into PACU, the PAED score of group 1 was significantly lower than those of group 2 and control group(P<0.05), while there was no significant difference between the latter two groups(P>0.05). Twenty and thirty minutes after entrance into PACU, the PAED scores of group 1 and group 2 were significantly lower than that of control group(P<0.05). There was no significant difference in the modified Aldrete score right after entrance into PACU among three groups. The pain scores of group 1 and group 2 were signifiantly lower than that of control group(P< 0.05). Conclusion Diclofenac sodium suppositories can decrease the incidence and severity of emergence agitation after sevoflurane maintenance in children undergoing adenotonsillectomy.

Objective To explore effects of parents exposure to TBT on blood routine of F1 generation mice. Methods 80 mice including 40 males and 40 females, were randomly divided into control groups (CK) , low dose groups (LTBT), middle dose groups (MTBT) and high dose groups (HTBT).They were given dose of TBT (0,0.2,2, 20μg/kg) every day.The experiment lasted 45 days.At 60 days, one female and one male of the same concentration were bred in the same cage according to 1∶1.At postnatal day 60, blood was collected for the determination of blood routine. Results Compared with control group, the number of red blood cells and hemoglobin of F1 generation male mice in LTBT and HTBT groups were significantly increased (P <0.01); Red blood cell volume, mean corpuscular hemoglobin (P <0.01), and the lymphocyte absolute value in F1 generation male LTBT were significantly reduced (P <0.05); HTBT of female mice were significantly increased about the number of red blood cells (P <0.01).A dose-dependent increase of the hemoglobin, red blood cells, and platelet count of F1 generation female experimental groups was observed.Conclusion Parental TBT exposure affects the F1 mice blood routine.There is the greatest influence on LTBT in F1 generation male mice and on HTBT in F1 generation female mice.

Objective To investigate the mechanism of linezolid resistance in methicillin-resistant Staphylococcus epidermidis ( MRSE) strains isolated in Hangzhou area. Methods Twenty-three linezolid-re-sistant Staphylococcus epidermidis ( LRSE) strains were isolated from the patients with septicaemia, urinary tract infection or infectious pleuritis in several hospitals in Hangzhou area during May, 2013 to April, 2015. The minimal inhibition concentrations ( MICs) of thirteen different antibiotics against the LRSE strains were detected by using E-test. Pulsed-field gel electrophoresis ( PFGE) and cluster analysis were performed for homology analysis. Correlations between linezolid resistance in the LRSE strains and G2576T mutation at theⅤ functional region of 23S rRNA gene or cfr gene were determined by PCR and sequencing analysis. Re-sults The MICs of linezolid to 15 LRSE strains were higher than 256 μg/ml while to the other 8 LRSE strains were 6 or 8 μg/ml. All of the 23 LRSE strains were resistant to both oxacillin and cefoxitin. Among the LRSE strains with high linezolid MICs (MIC>256 μg/ml), LRSE1 and LRSE2, LRSE3-LRSE6 and LRSE9-LRSE12 respectively belonged to the same clone line and came from the same hospital. All of the 23 LRSE strains carried the cfr gene. Moreover, the G2576T mutation at theⅤfunctional region of 23S rRNA gene was detected in the 15 LRSE strains with high linezolid MICs ( MIC>256 μg/ml ) , but not in the 8 strains with lower linezolid MICs ( MIC=6 or 8 μg/ml) . Conclusion There are significant differences in linezolid resistance among LRSE strains isolated in Hangzhou area. The LRSE strains are methicillin-resist-ant coagulase negative Staphylococcus ( MRCNS) strains and widely distributed. The linezolid resistance in LRSE strains is related to the G2576T mutation at theⅤfunctional region of 23S rRNA gene and cfr gene.

Objective To investigate the regulation of swimming motility by H-NS in Vibrio parahaemolyticus(VP). Methods VP was inoculated into the semi-solid swimming agar plate containing 1% Oxoid tryptone, 2% NaCl, 0.5%Difco Noble Agar, and 0.1% arabinose followed by incubation at 37℃ for 4.5 h before the diameters of bacterial lawns were measured.Total RNAs were extracted from the wild-type (WT) strains and the hns null mutant (Δhns), and the quantitative real-time( RT)-PCR( qRT-PCR) was carried out to calculate the transcriptional variation of flaA between WT andΔhns strains.The entire promoter DNA region of flaA was amplified and cloned into the lacZ fusion vector pHRP309 containing a promoterless lacZ gene. The recombinant lacZ reporter plasmid was transformed into WT and Δhns, respectively, to measure the β-galactosidase activities in cellular extracts using the β-galactosidase enzyme assay system. Results and Conclusion The phenotype results showed that swimming motility of VP was enhanced by H-NS.The qRT-PCR and LacZ fusion results indicated that the transcription of flaA was positively regulated by H-NS.Collectively, H-NS promotes the swimming motility of VP, at least partly, by activating the transcription of flaA.

Aim To investigate the alteration of Wnt/β-catenin signaling and sirtuins 1 in type 2 diabetic rats’ aorta and clarify its role in the development of di-abetes aortic disease. Methods The type 2 diabetes rat model was established by injection of streptozocin after five-week of high fat diet. The rats were randomly divided into control group, DM model group of 2 weeks, 4 weeks, 8 weeks and 12 weeks. Fasting blood glucose ( FBG ) , total cholesterol ( TC ) , triglyceride ( TG) , high density lipoprotein-cholesterol( HDL-C) , low density lipoprotein- cholesterol ( LDL-C ) and fast-ing insulin( FINS) levels were tested. HE staining was used to observe the pathological changes of aortal struc-tures. The alteration of Wnt2, β-catenin, TCF4, SIRT1 and sFRP2 in aortawas determined by Western blot and RT-PCR. Results Compared with control group, TC, TG, LDL-C levels of type 2 diabetic rats were significantly increased, HDL-C levels were signif-icantly reduced( P<0. 01 ) . Aortic histological analy-sis revealed that DM induced aortic endothelial cell vacuolar degeneration and necrosis. The expression of Wnt2 and β-catenin level increased significantly in the first 4 weeks of diabetic groups compared to control group, and that in model group of 8 weeks and 12 weeks kept in the high level and showed no significant alteration(P>0. 05). But the expression of TCF4 and SIRT1 was enhanced continuously in DM compared with control group while sFRP2 decreased in the duration of DM development. Conclusions Wnt/β-catenin signa-ling pathway was activated in diabetic aortal injury by regulation of SIRT1 via sFRP2 . Further researches on its mechanism of actionin DM aorta injury may find a new therapeutic target for the disease.

OBJECTIVETo study the regulatory effect of Yishou Tiaozhi Tablet (YSTZT) on blood lipids in patients with primary hyperlipidemia.

METHODSOne hundred and sixty-eight patients with primary hyperlipidemia were randomly divided into two groups. The treated group was treated with YSTZT 4 tablets 3 times a day, and the control group was treated with Zocor by oral taking 1 tablet before sleep every evening. The therapeutic course for both groups was 60 days. The effect in regulating blood lipids in patients was observed.

RESULTSThe levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), arteriosclerosis index (AI), apo-lipoprotein B (apoB), TC/HDL-C lowered and apoA/apoB ratio increased obviously in the treated group. As compared the effects between the two groups, the lowering of TC, AI and apoB in the two groups were similar (P > 0.05), effect of YSTZT in lowering TG was superior but in lowering of LDL-C was inferior to those of Zocor respectively (all P < 0.01). The effect of both remedies in elevating HDL-C was not satisfactory. The total effective rate of YSTZT was 91.9%, its individual effects were similar to those of SJZ respectively except in lowering TG and raising HDL-C. The adverse reaction occurred in YSTZT treatment course was mild without any influence on the medication.

CONCLUSIONYSTZT had definite regulatory effect on the blood lipids and lipoproteins in patients with hyperlipidemia.
