Objective To investigate the role of compound traditional Chinese medicine Yiqilin in the regulation of immune-related genes expression in spontaneously hypertensive rats(SHR).Methods Ten SHR were randomly divided into test group(fed with Yiqilin and ordinary food at the ratio of 1:9 for 6 months,n=5)and control group(fed with ordinary food for 6 months,n=5).Total RNA was extracted from myocardial tissues of SHR after 6 months,and gene chip hybridization technique was employed to analyse the expression of immune-regulated genes of myocardial tissues in two groups.The genes with differentiation expression were screened,and were verified by Real-time PCR.Results The expression of 32 immune-related genes were up-regulated in the test group,including interleukin(IL)6 receptor,IL-6 signal transduction factor,chemotatic factor,antigen presenting molecule,antibody receptor,heat shock protein(Hsp), etc.No immune-related gene was down-regulated in test group.The results of 2 immune-related genes(Hsp 105 and Hsp 90)detected by Real-time PCR were consistent with those by gene chip hybridization.Conclusion Part of the immune-related genes in myocardial tissues in SHR may be up-regulated by Yiqiling,which indicates that Yiqiling may play a role in the regulation of expression of immune-related genes in SHR.

The changes in cell adhesion molecule CD15 and PECAM-1 in grafted renal tissue from 18 cases of acute allograft rejection were studied by immunohistochemistry techniques (SP method ) and computerized imaging analysis system. The results showed that: (1) CD15 positive expression level was higher in acute allograft rejection than that in normal renal in tuberular cells.(2) PECAM-1 expression level was lower in glomerular endothelial cells, but higher in tuberular cells than those in normal renal tissue during acute allograft rejection. The above findings suggested that the detection of CD15 and PECAM-1 in the grafted kidney might have some values in the diagnosis of acute allograft rejection.

ObjectiveTo evaluate the role of detecting early change of left ventricular regional myocardial function in the rabbit with type Ⅰ diabetes using omni-directional M-mode echocardiography (OME).MethodsEighty New Zealand rabbits were selected in this study..40 health rabbits were included in the control group,the other 40 with type Ⅰ diabetes were included in the experiment group.The OME was used to measure the peak time of myocardial motion during systole (Ts) and diastole (Td),myocardial velocity gradient during systole (MVGs) and diastole (MVGd) on the left ventricular short axis.These parameters were measured during the first,second,fourth,sixth and eighth week.ResultsOME was able to detect significant changes of Td during the second week,Ts and MVGd during the fourth week,and MVGs during sixth week after modeling ( P ＜0.05 ).ConclusionsOME is an important method to detect early changes of regional myocardial function in the patients with diabetes.

This study aimed to investigate the drug susceptibility of wild-type and mutant avian influenza A (H7N9) virus neuraminidase (NA) to oseltamivir and zanamivir. Codon optimized DNA of H7N9 (A/ Hangzhou/1/2013) NA was synthesized and constructed into the pcDNA3.1/His vector (NA(H7N9-WT)). Mutant NA(H7N9-H274Y) and NA(H7N9-R292K) plasmids were constructed by directed mutagenesis PCR using NA(H7N9-WT) plasmid as the template followed by sequencing. NA plasmids were transfected into 293T cells and cell lysates containing NAs were collected 48 h post-transfection. Wild-type and mutant NAs were analyzed by Western blotting and their activities were tested by the 4-MUNANA-based assay. All three NAs were expressed and enzymatic activities were confirmed. The effects of oseltamivir and zanamivir on all three NAs were then tested. It showed that the half maximal inhibitory concentrations (IC50s) of oseltamivir carboxylate on NA(H7N9-WT), NA(H7N9-H274Y) and NA(H7N9-R292K) were 1.6 nM, 15.1 nM, and > 1 000 nM with fold changes of 9 and > 625, respectively. The IC50 values of zanamivir on NA(H7N9-WT), NA(H7N9-H274Y), and NA(H7N9-R292K) were 1.1 nM, 1.4 nM, and 38.0 nM with fold changes of 1.3 and 34, respectively. These results indicated that oseltamivir and zanamivir could significantly inhibit NA(H7N9-WT). NA(H7N9-R292K) showed high-level resistance to both drugs (34-fold and 625-fold) and NA(H7N9-H274Y) was sensitive to both (1.3-fold and 9-fold). These results indicated that both oseltamivir and zanamivir could be used for patients infected with the H7N9 virus. However, when patients carried the H7N9 virus with a NA R292K mutation, other medications would be preferred over oseltamivir or zanamivir.
