The adhesion of cells to each other and to the proteins of the extracellular matrix provides a stable environment for cell growth, differentiation and migration. This is a prerequisite for the normal function of the cardiovascular system. Thus the abnormal adhesion function may play a key role in the pathogenesis and development of cardiovascular diseases. To date, there are six main groups of adhesion molecule, and integrins family are the largest and most broadly distributed of the families of cellular adhesion receptors. They have an important role in several aspects of cardiovascular diseases and that its regulated inhibition leads to a reduction in incidence and mortality due to these disorders. This review focuses upon the structure、mechanism and their roles in cardiovascular diseases which maybe facilitate the development of novel therapies.

Objective:To analyze the advantages of the pressure-regulated volume control (PRVC) mode compared with the traditional continuous mandatory ventilation (CMV) mode about mechanical ventilation efficiency of ventilator.Methods: For the mechanical ventilation situations, the parameters of PRVC mode, V-CMV mode and P-CMV mode under same detecting conditions were tested by using gas analyzer, which based on the ventilation principle of PRVC mode. And then the differences between PRVC mode and CMV modes were analyzed. Results: PRVC mode can supply the almost same tidal volume, and provide lower pressure and higher compliance compare with the V–CMV mode under the same conditions. On the other hand, PRVC mode can supply more tidal volume and slightly higher compliance compare with the P–CMV mode under the same pressure.Conclusion: PRVC mode has combined with the advantages of CMV mode, and it can make sure the target tidal volume, at the same time, reduce the pressure of airway, and improve the compliance for circuit. It also can make the mechanical ventilation to got more efficiency and more safety.

Object To determine the variety of aconitine and tetrandrin in decocting Radix Aconiti and Radix Stephaniae Tetrandrae separately and compatibly, and explore the mechanism of synergy between above two decocted herbs. Methods TLCS was used to determine the contents of aconitine and tetrandrin in separate decoctions and compatible decoction, respectively. Results The contents of both aconitine and tetrandrin were less in compatible decoction than in separate ones. Conclusion A scientific basis is provided by the compatible decoction of the two herbs for more effective and attenuate use.

Background Central corneal thickness (CCT)is an important parameter to evaluate corneal healthy status and is crucial for surgical planning.However,clinical study found that the center of cornea does not correspond to the thinnest point of cornea.Thus,it is essential to characterize the minimum corneal thickness(MCT) and its location.Objective Present study was to determine the thickness and location of MCT and its relationship to the fellow eye using Pentacam High Resolution technique.Methods The 564 eyes from 282 Chinese myopic patients were reviewed in this study.The CCT,MCT,pupillary central corneal thickness(PCT) and x-y coordinate of thinnest point were bilaterally measured.Written informed consent was obtained prior to the ocular biomedical measurement.Results CCT was (540.07±31.78) μm in the right eyes and (539.24±31.06) μm in the lefi eyes; PCT was (540.25±30.75)μm in the right eyes and (539.48±31.00)μm in the left eyes.MCT was (537.87± 31.91)μm in the right eyes and (536.35±31.24)μm in the left eyes,showing significant differences in all the parameters between the right eyes and left eyes expect for PCT(CCT:P=0.046;PCT:P=0.065 ;MCT:P=0.000).The C CT,PCT and M CT were significantly correlated between the right eyes and left eyes (r =0.97,0.97,0.98,P＜ 0.01).Bland-Altman plot showed a good consistence between the both eyes.The mean distance from the center was (0.50±0.21) mm in the right eyes and (0.56±0.22)mm in the left eyes,showing a significant difference (P =0.000).The difference between CCT and MCT was approximately (2.20±1.74)μm in the right eyes and (2.88±1.75) μm in the left eyes.The location of MCT in both the right eyes and left eyes tended to symmetry along the vertical midline.The distance between the R (x,y) to transformed L (x,y) was (0.29 ± 0.17)mm and the angular distance was (28.28±28.21)degree.Conclusions This study offers a range of MCT and its location in Chinese myopic patients.The difference exists between the CCT and MCT in bilateral eyes.The location of the thinnest point tends to be symmetrical along the vertical midline between the both eyes.The changes of these parameters may be helpful for the diagnosis of some corneal diseases.

Objective To explore the diagnostic value of contrast-enhanced ultrasonic intravenous imaging and cholangiography in the diagnosis of malignant jaundice obstructive. Methods Forty three patients who were diagnosed with malignant obstructive jaundice by contrast-enhanced computed tomography and contrast-enhanced computed magnetic resonance imaging were enrolled in this study. All of them underwent conventional ultrasound, IV-CEUS and IC-CEUS. According to the results of operation, the diagnosis accuracies were compared among conventional ultrasound, IV-CEUS, IC-CEUS and IV- CEUS combined with IC-CEUS. Results Diagnostic accuracy by the conventional ultrasound , IV-CEUS , IC-CEUS and IV- CEUS combined with IC-CEUS were 72.1%(31/43), 83.7%(36/43), 81.4%(35/43) and 93.0%(40/43), respectively. IV- CEUS combined with IC-CEUS was superior to the conventional ultrasound (P = 0.021). There were no significant differences when the conventional ultrasound was compared with IV-CEUS or IC-CEUS alone (P = 0.194 and 0.307). Conclusions Preoperative evaluation by IV- CEUS combined with IC-CEUS can elaborate the intra-cavitary and extra-cavitary changes of malignant obstructive jaundice. The diagnostic accuracy rate could be effectively improved by IV-CEUS combined with IC-CEUS, which can bring favorable clinical benefit.

Objective:To detect the interleukin-22(IL-22) levels in peripheral blood of the asthma patients and analyze the relationship between the IL-22 levels and IgE,pulmonary function,fractional exhaled nitric oxide(FENO),and to investigate the role of IL-22 in the pathogenesis of bronchial asthma. Methods:Seventy-eight patients with asthma were selected as experiment group.The asthma patients were divided into increased IgE group (n=46)and normal IgE group(n=32)according to the IgE levels.The asthma patients were also divided into acute attack stage and clinical control stage according to patients' clinical symptoms.In addition, twenty healthy controls were chosen as healthy control group.The plasma IL-22 levels, IgE,forced expiratory volume in one second (FEV1) and FENO levels of the subjects in various groups were detected and compared between various groups.The correlations between the plasma IL-22 levels and IgE, FEV1,FENO were analyzed.Results:The plasma IL-22 level and FENO level of the patients in asthma group were higher than those in healthy control group(P<0.05).The IL-22 level and FENO level of the patients in clinical control stage were lower than those in acute attack stage,but they were still higher than those in healthy control group(P<0.05).The plasma IL-22 level of the patients in increased IgE group was higher than that in normal IgE group(P<0.05).There were significant negative correlations between the IL-22 levels and FEV1 in the asthma patients in acute attack group and clinical control group(r=-0.365 3,P<0.05;r=-0.267 2,P<0.05),but there was no significant correlation between the IL-22 levels and FENO(r=0.011 9,P>0.05;r=0.059 8,P>0.05).Conclusion:The increased expression of IL-22 in peripheral blood of the patients with asthma may participate in the pathogenesis of asthma,and may aggravate the deterioration of pulmonary function of the asthma patients.

Objective To investigate the clinical value of contrast-enhanced ultrasonography(CEUS) in evaluating treatment response of hepatocellular carcinoma after interventional therapy. Methods One hundred and three patients with 136 lesions of hepatocellular carcinoma confirmed by pathology were examined by common color ultrasound (US), contrast-enhanced CT, CEUS and DSA pre- and post-interventional treatment respectively. Results The sensitivity,specificity and accuracy of CEUS for focus judgment after interventional therapy were 95.8%, 95.6% and 98. 5% respectively. The sensitivity, specificity and accuracy of US in detecting tumor deactivation and residue were 92.3% ,77.4% and 83.1% respectively. CEUS were highly consistent with the results of enhanced CT/DSA (Kappa = 0.93) and significantly higher than those of US (Kappa = 0.66). Conclusions CEUS is useful to monitor the efficacy and guide treatment after interventional therapy.
