Objective:To assess effect of age on the characteristic of letf ventricular (LV) twist-displacement loop in health volunteers by velocity vector imaging (VVI) and to provide a new method for LV function evaluation in clinic.
Methods:Atfer obtaining basal and apical LV short-axis images in 98 healthy volunteers (18-75 years old) by 2-dimensional echocardiography, we use VVI sotfware to analysis LV twist motion and radial displacement at each plane off-line. hTe peak LV twist (Ptw), the peak untwist velocity (PutwV), the proportion of untwist in isovolumetric relaxation period (Iutw%) and LV radial displacement (Dis) were measured and calculated. Then we constructed LV twist-displacement loop and compared the characteristic of them among different groups.
Results:Ptw increased gradually with the increase in age. The biggest PutwV was in the group of 30-60 years old. Iutw%increased gradually before 60 years old, then decreased atfer that. Dis was not obviously different among the three groups. hTe characteristic of LV twist-displacement loop was like the configuration of 8. There was a linear relation between twist and displacement during systole, and the slope increased gradually with the increase in age. During early diastole, the relatively small radial expanding displacement displayed with untwisting, resulting in a much steeper twist-displacement relationship curve occurred in each group, which was getting smooth gradually when the radial expanding displacement increased during mid to late diastole.
Conclusions:VVI can be used to effectively and noninvasively assess LV twist-displacement loop with change in age and provide important information for LV function. hTe effect of age must take into account when evaluate the LV function by the twist-displacement loop.

Objective:To investigate the LOH at regions on chromosomal arm 8p22,11p15,17p13 and its relationship with clinicopathological parameters. Methods:Thirty-four paraffin-embedded tumor and corresponding noncancerous tissues were analysed. PCR was used to amplified three microsatellite markers D8S136,D11S988 and TP53 located at these chromosomal regions. PCR products were electrophoresed on 6%polyacrylamide gel and detected using silver staining. The P53, c-erBb-2,PR,ER status were determined by immunohistochemistry. Results:Of the three markers we studied, D8S136 was detected LOH at a frequency of 12 in 34 tumors(35.29%). D11S988 and TP53 were detected LOH at a frequency of 5 in 34 tumors(14.71%). There were no obvious associations between LOH at D11S988、TP53 and clinicopathological parameters, but the tumors with LOH at D8S136 were significant larger than that without LOH(P=0.0049). Conclusion: Invasive ductal carcinoma of the breast has a frequent LOH on chromosome 8p22. The loss or inactivation of putative tumor suppressor genes on 8p22 may contribute to the excessive growth of the tumors.

In this paper, based on the special influence of supramolecular chemistry on the basic theory of Chinese medicines ( CM) , the authors further analyzed the history of meridian tropism and natural origins of CM organisms and explained CM ingredients and the universal regularity of the automatic action of the supramolecular "imprinting templates" hole channel structure. After entering human bodies, CMs, as the aggregation of supramolecular "imprinting templates" , automatically seek supramolecular subjects that are matched with their "imprinting templates" in human meridians and organs for the purpose of self-recognition, self-organization, self-assembly and self-replication, so as to generate specific efficacy in meridians and organs, which is reflected as the meridian tropism phenomena at macro level. This regularity can be studied by in vitro and in vivo experimental studies. In vitro methods are mostly supra molecular structure analysis and kinetic and thermodynamic parameter calculation; Whereas in vivo methods are dominated by the analysis on object component distribution, chromatopharmacodynamic parameters and network chromatopharmacodynamic parameters; Particularly, the acupoint-medicine method can simplify to study the supramolecular subject-object relations. Consequently, CM's'meridian tropism reveals the universal regularity for interactions of macromolecular and micromolecular "imprinting templates" of subjects and objects in natural organisms. As the first barrier for the material base of the CM theory and breakthrough in the modernization of the basic CM theory, meridian tropism plays an important role in studies on basic theories of the basic CM theory.

OBJECTIVEDevelopment of new methods, ELISA and immunostrip test, for the diagnosis of nasopharyngeal carcinoma.
METHODSThe engineering purified antigens coat plate or absorb on nitrocellulose filter. The plate and diagnostic strips carrying antigens were used for detection of IgG antibody in the sera from nasopharyngeal carcinoma patients and outpatients patients.
RESULTS127 cases sera from nasopharyngeal carcinoma patients were parallel detected TK/IgG antibody by ELISA and immunostrips. The TK/IgG antibody are all positive in the 127 cases of nasopharyngeal carcinoma patients. 55 cases show positive by ELISA, 58 cases positive by immunostrips in 247cases sera from outpatient. The antibody positive rate to early antigen p54 lower then to TK. Conclusion ELISA and imuunostrips are sensitive and specific means for detection of the IgG antibody to TK of EBV and the diagnosis of nasopharyngeal carcinoma.

OBJECTIVETo investigate the regulatory effect of Jiangu Granule (JGG) on osteoblast and its effect on bone absorption on the molecular level and from aspect of bone metabolism.
METHODSOsteoporosis model SD rats established by ovariectomy were interfered by drug. Levels of urinary deoxypyridinoline (D-Pyr) and osseous integrin beta1 (Itgbeta1) mRNA expression were detected by ELISA and in situ hybridization, respectively.
RESULTSLevel of urinary D-Pyr increased (P < 0.01) and osseous Itgbeta1 mRNA expression decreased significantly in the model rats. After treatment with JGG for 12 weeks, the D-Pyr levels in them decreased significantly (P < 0.05), while the quantity of osteoblasts and the expression of Itgbeta1 mRNA in bone tissue increased obviously. Conclusion JGG can not only decrease the catabolism of collagen fiber type I in bone matrix, but also promote the osteogenic activity of osteoblast. So, it can improve or reverse the pathological tendency of osteogenesis shortage caused by E2 reduction to play its action in strengthening bone.
