Objective To study the esthetic indexes of soft tissue profile in lateral face in Anhui youths with normal occlusion. Methods The study was carried out by taking the cephalometric photographs in the 102 Anhui youths with normal occlusion. The data of measurement were got from the photographs by image database and analysis system (IDAS) software, and statistically evaluated by SPSS software. Some specially selected items were analysed again by Fisher's discriminant method. Results Seven items, i.e. Li Ns Pos, Ls Ns Pos, Ls B, Li B, Sn H, Bs Li FH and Z angle, were chosen as esthetic indexes of facial profile, and the discriminant functional formula was established. Conclusion Combination of all the above 7 items contribute to the beauty of facial profile.

Purpose:To explore the preventive effect of hepatic arterial infusion (DDS) against recurrence of hepato- cellular carcinoma (HCC) after radical resection.Methods:From Jan,1996 to May,1998,287 patients of HCC after radical resection were randomly divided into four groups:intra-hepatic arterial infusion(97),intra-portal vein(80),intra-hepatic artery and portal vein (60),control (50).All patients received chemotherapy for two years and observed for postoperative recurrence of HCC.Results:The postoperative recurrence rate of HCC with intra-hepatic arterial infusion was significantly lower than that of intra-portal vein (P0.05).The 1～、2～ and 3～year survival rate of intra-hepatic arterial infusion was significantly higher than any of the other groups.Conclusions:Intra-hepatic arterial infusion (DDS) through gastro-duodenal artery can effectively pro- long the postoperative survival and decrease the post-operative recurrence rate of HCC.The preventive method of DDS through gastro-duodenal artery was safer and effective.

Human herpesvirus 7 (HHV-7) infection is dependent on the functions of structural glycoproteins at multiple stages of the viral life cycle. These proteins mediate the initial attachment and fusion events that occur between the viral envelope and a host cell membrane, as well as cell to cell spread of the virus. To characterize the HHV-7 glycoproteins that can mediate cell fusion, a cell-based fusion assay was used. 293T cells expressing the HHV-7 glycoproteins of interest along with a luciferase reporter gene under the control of the T7 promoter were cocultivated with SupT1 cells transfected with T7 RNA polymerase. HHV-7 glycoproteins gB, gH, gL and gO can mediate the fusion of 293T cells with SupT1 cells, and the fusion can be inhibited by anti-CD4 mAbs. Thus, the coexpression of HHV-7 gB, gO, gH and gL is sufficient and necessary for HHV-7 induced membrane fusion, and one of these glycoproteins or protein complex formed by these glycoproteins might be the ligand(s) of CD4 molecule.

Objective To build a set of inexpensive wireless wide area network PACS based on open source code.Methods To improve the open source code MyFreePACS on Internet.Results The basic function of PACS can be achieved in an economical way,using internet explorer to browse and deal with the DICOM Images,with the capability of such functions as displaying and managing of the pictures.It is possible to make rounds at patient bedside with wireless device and remote medical consultation with specialists through Internet.Conclusion It is possible to utilize the free open source code MyFreePACS on the internet to construct an economical PACS on Web in the medium and small-scale hospital.

To observe the effect of calycosin on the proliferation and activation of primary hepatic stellate cells (HSCs) in rats, and prove calycosin shows the effects through peroxisome proliferator-activated receptor γ(PPARγ) and farnesoid X receptor (FXR). The results indicated that calycosin could inhibit HSC proliferation and expressions of activation marker smooth muscle actin-α and type I collagen. With the increase in HSC activation time, FXR expression reduced, but with no notable impact from calycosin. Calycosin could up-regulate PPARγ expression and its nuclear transition in a concentration-dependent manner. Its prohibitory effect on HSC activation could be blocked by PPARγ antagonist. In conclusion, calycosin could inhibit HSC activation and proliferation, which may be related with the up-regulation of PPARγ signal pathway.

As the largest research-oriented specialty department in national traditional Chinese medicine hospitals, the Department of Critical Care Medicine in Guangdong Provincial Hospital of Chinese Medicine insists on the development mode combined with clinical medicine and scientific research. By taking clinical and basic researches for integrative medicine preventing and treating acute myocardial in-farction and sepsis as a breakthrough, authors explored key problems of Chinese medicine in improving the prognosis related diseases and patients' quality of life. In recent 3 years our department has successively become the principal unit of the national key specialties cooperative group of critical care medicine (awarded by State Administration of Traditional Chinese Medicine), the key clinical specialties (awarded by National Health and Family Planning Commission), and Guangzhou key laboratory construction unit, and achieved overall lap in clinical medical treatment, personnel training, scientific research, and social service.
