Objective To ascertain the utility and difference of sonography with echo-tracking (ET) technique and pulse-Doppler to assess vascular stiffness in rats with hypercholesterolemia and atherosclerosis.Methods Sonography associated with ET technique and pulse-Doppler were used to measure stiffness parameter (β),arterial compliance (AC),distensibility coefficient (DC),one-point pulse wave velocity (PWVβ),resistence index(RI),peak systolic velocity(PSV),end-diastolic velocity(EDV) and EDV/PSV of the aorta in cholesterol-fed SD rats (group T1,n =10,for 4 weeks;group T2,n =10,for 12 weeks) and normal control rats(group C1,n =10;group C2,n =10).All parameters and blood biochemical markers[total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-CH) and highdensity lipoprotein cholesterol (HDL-CH)] among groups were analyzed with ANOVE factor analysis.Correlation was analyzed with Pearson analysis.Light microscopic evaluation were used to demonstrate atherosclerotic changes in the aorta.Results The PWVβ value and PSV of the aorta between group T1 and T2 were significantly different (P =0.001,P <0.05).The β,PWVβ values of the aorta in group T1 and T2 were significantly higher than those of group C1 and C2 (P <0.05).AC and DC values of the aorta in group T1 and T2 were significantly lower than those of group C1 and C2 (P <0.05).Correlation analysis showsed that RI was positively correlated with systolic pressure(P <0.05).All parameters had correlated with each other among β,PWVβ,AC,DC,TG,TC,systolic pressure and diastolic pressure.DC and AC were negatively correlated with β and PWVβ,also DC was negatively correlated with TG.Light microscopy confirmed morphologic typical changes of aortic atherosclerosis in group T1 and T2.Conclusions Sonography with the ET method compared with pulse-Doppler is much more sensitive and it can be used to evaluate tissue elastic changes in arterial walls associated with atherosclerosis and hypercholesterolemia.PSV can reflect atherosclerosis of rat's abdominal aorta well,but pulse-Doppler is limited in the diagnosis of earlier atherosclerosis period.

Objective To explore the clinical regularity of drugs on epidemic encephalitis B with text mining technique. Methods The data set on epidemic encephalitis B was downloaded from CBM database. The regularities of Chinese herbal medicine, Chinese patent medicine (CPM), western medicine and the combination of CPM and western medicine on epidemic encephalitis B were mined by data slicing algorithm. The results are showed visually with Cytoscape 2.8 software. Results The main function of herbal pieces was focused on clearing heat and removing toxicity. The herbal pieces such as Rehmanniae Radix Isatidis Raxis, Isatids Folium, Paeoniae Radis rubra and Scutellariae Radix were most often used. Angong Niuhuang Wan and Qingkailing Injection were usually used as CPM. For western medicine, antiviral drugs such as interferon and ribavirin were often used, and they were often used together with brain cells nutrition medicine, hormone, immunopotentiator and so on, and they were also frequently used together with CPM such as Angong Niuhuang Wan and Qingkailing Injection. Conclusion Text mining approach provides an important method in exploring the medication regularity for diseas, and provide refenrence for clinical use.

Objective To assess the impact of the virus on the complementary determining region 3 (CDR3) length diversity of T cell receptor(TCR) Vβ repertoires of CD4+ T lymphocytes and to explore its association with viral load in individuals with HIV-1 infection. Methods The TCR repertoire was examined using spectratyping of CDR3 length diversity within CD4+ T cells in HIV infected and healthy adults. Separation of CD4+ T cells from peripheral blood mononuclear cells ( PBMCs) was carried out by using immunomagnetic beads coated with anti-CD4 antibody. Total RNAs from the purified CD4 + T lymphocytes were isolated and used to perform nested-PCR amplifications in CDR3 of 22 TCR gene families. CDR3 diversity and its association with viral load in individuals with HIV-1 infection were analyzed. Results An average diversity for all CDR3 profiles in CD4+ T cells from 25 HIV-infected individuals was significantly different as compared to 10 age-matched healthy donors (P<0.05) with the HIV-infected individuals losing diversity in the CDR3 profiles. There was positive correlation between changes in TCR CDR3 diversity and viral load (r = 0. 494, P < 0. 05). The changes in CDR3 length diversity of Vβ families in HIV-infected individuals, particular in Vβ8, Vβ22, Vβ23 were statistically different from the healthy controls. Conclusion HIV-1 infection might induce the loss of TCR Vp repertoire diversity and disrupt the CDR3 Gaussian distributions within CD4 + T cells. There should be positive correlation between changes in TCR CDR3 diversity and the viral load in HIV-1 infected patients.

OBJECTIVEThis study was designed to detect the expression of bcl-2 and p53 proteins in colorectal carcinomas and to determine their association with the patient survival and stage of the diseases.
METHODSImmunohistochemistry method was used to detect the expression of bcl-2 and p53 proteins in 93 cases of colorectal carcinoma. The stain results were obtained by analyzing the clinic-pathological characteristics of patients.
RESULTSFifty-seven percent (53/93) of the colorectal carcinomas were bcl-2 protein positive. The positive rate of bcl-2 protein in lymph node involvement cases was lower (15/37) than the cases without node involvement (38/58, P<0.01). The positive rate of p53 protein was 43% (40/93) in colon-rectum carcinomas. No significant correlation was observed between p53 protein expression and clinic-pathological manifestations (P>0.05) but the survival was significantly worse (P=0.0001) in the p53 protein positive cases. Neither bcl-2 nor p53 alone was correlated with stage of the disease. When combined bcl-2/p53 status was analyzed, a group with bcl-2(+) and p53(-) had the best prognosis. This group was significantly associated with earlier Dukes' stages (P=0.1763). In multivariate Cox regression analysis, lymph node involvement and p53 protein expression were two independent factors correlated with survival time.
CONCLUSIONThe expression of bcl-2 and p53 represent biological characteristics of colorectal carcinomas. Assessment of both bcl-2 and p53 status may be valuable in predicting the prognosis of patients.
