Objective To observe the therapeutic effect of periodical treatment of Sanjiexiaopi decoction on hyperplasia of mammary gland during premenstrual phase. Methods 110 cases were randomly recruited into a treatment group and a control group with 55 case in each group. The treatment group was given Sanjiexiaopi decoction 7 days before menstruation, and the control group was given Rupixiao tablet. Both groups received no treatment during menstruation and were treated for three months. Patients in both groups underwent molybdenum target X-ray photographs and infrascan before and after the treatment. Therapeutic effects of the two groups.were compared. Results The total effective rate was 96.4% and 81.8% in the treatment group and the control group respectively. The patients in treatment group showed obvious improvent than the control group in terms of X-ray photographs and infrascan, having statistical significance (P<0.05) . Conclusion Sanjiexiaopi decoction has obvious effects on hyperplasia of mammary gland during premenstrual phase.

Aim To observe the protective effects of total saponi ns of tribulus (TST) on cerebral ischemia reperfusion injury in rats. Meth ods Rat cerebral ischemia-reperfusion injury was induced by middle cer ebral artery occlusion .The neurological outcome was evaluated. CK, LDH and NO a ctivity in serum,SOD and MDA levels of cerebral tissue were measured. Re sults The levels of CK,LDH,NO,SOD and MDA in TST(30 mg?kg -1,1 0 mg?kg -1) groups were significantly lower than those in model group. The level of cellular and intercellular edema was reduced markly in the pathomorpho logy examination. The neurological deficits was decreased by TST.Conclus ion TST has protective effects on cerebral ischemia reperfusion injur y in rats.

Objective To observe the hemodynamic change of small artery in patients with type 2 diabetes. Methods We measured peak systolic velocity (PSV), end-diastolic velocity (EDV), pulse index (PI), resistance index (RI) of ocular artery (OA), central retinal artery (CRA), finger artery, dorsal pedis artery and interlobar artery of patients with early-stage type 2 diabetes. Results The decrease in PSV and EDV values occurred early in CRA of type 2 diabetics while RI and PI values increased. Conclusion The hemodynamic change of CRA occurs earliest among general small arteries of type 2 diabetic patients.

AIM： To investigate the tumorigenicity of lung cancer by learning the accumulation of p53 and the exposure of cytokeratin 18 neo-epitope(CK-18neo) related to the clinicopathological parameters in non-small cell lung cancer(NSCLC). METHODS: To detect the monoclonal antibodies of p53 and M30 CytoDEATH(specific antibody for CK-18neo) in 62 cases of NSCLC (included 29 cases of squamous cell carcinoma and 33 cases of adenocarcinoma) and 10 cases of control group by adopting immunohistochemistry assay (LSAB). Moreover, the immunoreactivity of p53 was quantitatively evaluated with positive unit (PU). RESULTS: (1) p53 immunoreactivity was positive in 15 of 29 squamous cell carcinoma (51.72%), 15 of 33 adenocarcinoma (45.45%), 30 of 62 NSCLC (48.39%). In 10 control cases was negative. There were significant differences between these groups (P＜0.01). (2)In 62 cases of NSCLC, AI% of M30 is 1.10%, and in 29 cases of squamous cell carcinoma is 0.95%, and in 33 cases of adenocarcinoma is 1.24%. In 10 control cases, the AI% is 1.06%. There is not significant difference among these groups . (3) According to the results of Pearson's correlation analysis, we found positive linear correlation between the immunoreactivity of p53（-/+）, p53（5 degrees）and p53（PU）(P＜0.01). CONCLUSION: Our results suggested that the pathogenesis of NSCLC might be related to the mutation of gene p53 and cell excessive proliferation and insufficient apoptosis.

Through the experiments of producing spherical steel-bullet (4.763mm in caliber and 0,44gm in weight) wound on the hind legs of 17 dogs, the authors re- ported that there was a definite linear relationship between the reactions of the serum creatine kinase and the amount of kintic energy from the high speed of the bullets absorbed by the tissues and also with the weight of dead tissue removed around the bullet-path, Within the first 6 hours after injury, the activity of SCK increased with the rise of the biologic effect values of the amount of the kinetic energy absorbed and the weight of the dead tissue removed.

Objective To investigate the feasibility of recombinant adeno-associated virus encoding secrected forms of human acidic fibroblast growth factor transfecting endothelial progenitor cells.Methods sp-haFGF was obtained through combining signal peptide sequence of FGF-4 with native aFGF gene by PCR.sp-haFGF was cloned into AAV vector plasmid pAAV-IRES-hrGFP.Recombinant AAV encoding sp-haFGF was packaged through co-transfecting HEK293 cells with plasmid sp-haFGF-pAAV-IRES-hrGFP,pAAV-RC and pHelper.Ex vivo cultured EPCs were infected with concentrated rAAV.Expression of green fluorescent protein(GFP) in infected EPC was observed by fluorescence microscope and expression of sp-haFGF in EPCs was verified by RT-PCR and western blot analysis.Results Recombinant AAV encoding sp-haFGF was obtained.After EPCs being infected with rAAV,green fluorescence was found in about 20～30% EPCs,gene of(560 bp) was generated from EPCs by RT-PCR method,and(sp-haFGF) protein was detected in infected cells.Conclusion EPC was efficiently infected by rAAV encoding(sp-haFGF) and(haFGF) was expressed by EPCs,which establishes a basis for therapeutic angiogenesis by transgenic EPCs transplantation.

AIM: To isolate peptides targeted binding and internalizing into glioblastoma cell line SWO-38. METHODS: Tumor cells were screened five rounds of whole cell screen through the Ph.D.-12 phage display library. The monoclone specific binding efficiency to the tumor cell was analyzed, and the DNA of phages were extracted, sequenced and translated to the sequences of amino acid. RESULTS: In the phage library after five rounds of screen , 10 of 13 monoclones had highly selective binding to SWO-38 cells. We found two repeated peptide sequences. CONCLUSION: Whole cell screening against tumor cells through random phage peptide library can obtain phage peptides with highly specific binding and internalizing ability. The peptides could be used as a therapy vector for tumor targeted delivery.

Through sequencing, the sequences of displayed peptides were obtained. CONCLUSIONS: Whole cell screening against EAC cells through random phage peptide library can obtain phage peptides with a highly tissue specific binding and internalizing ability. The peptides do provide a basis for tumor's targeted delivery as therapy vector.
