Objective:To investigate the influence of sCD80-Linker-sCD40L fusion protein on the unspecific anti- tumor immunity in vitro.Methods:Ovarian cancer SKOV3 cells were separately transfected with recombinant adenoviral vectors containing sCD80-Linker-sCD40L fusion gene,sCD80 gene,sCD40L gene or with control adenovirus.The expres- sion of the sCD80-Linker-sCD40L fusion protein,sCD80 protein and sCD40L protein in the supernatants of SKOV3 cells was determined by ELISA.Dendritic cells(DCs)were cultured with peripheral blood mononuclear cells from a patient with ovarian carcinoma.DCs and autologous T cells were co-cuhured and were exposed to different supernatants for 48 h. The allostimulatory effects of DCs on T cells were determined by mixed lymphocyte reaction(MLR).The unspecific kill- ing activities of induced T cells against SKOV3/K562 cells were measured by LDH-releasing assay.Results:ELISA assay showed that levels of the sCD80-Linker-sCD40L fusion protein,sCD80 protein and sCD40L protein in the supernatants of transfeced SKOV3 cells were 2.791 ng/ml,1.956 ng/ml and 1.407 ng/ml,respectively.The fusion protein-exposed DCs ([0.382?0.053]vs[0.167?0.028],P
2.Development of effervescent tablet of Chinese traditional medicine and its technology study.
China Journal of Chinese Materia Medica 2004;29(7):624-627
Effervescent tablets which contain an effervescent mixture of a suitable organic acid and an alkali metal bicarbonate and/or carbonate can give out carbon dioxide when they meet water. The effervescent tablets for oral solution can be dissolved in cool water about 17-20 degrees C, therefore it is convenient to carry and use. It also has a good taste for patient with deodorizing agent added. The foam produced by external effervescent tablets is usually helpful in killing the local bacteria. The review displayed the main supplementary material, preparative technique and the study development of effervescent tablets of Chinese traditional medicine. Effervescent tablets that have been used to clinic were enumerated.

OBJECTIVETo observe the efficacy of Sanjie Zhentong Capsule (SJC) in treating ovarian cyst after ovulation-induction.
METHODSFifty-eight patients with ovarian cyst were randomly assigned to two groups, 33 in the treated group treated with SJC and 25 in the control group treated with temporization for 1 month. Changes of estradiol (E2), luteinizing hormone (LH) and follicle stimulating hormone (FSH) level as well as condition of cyst before and after treatment were observed and compared. And the time for complete disappearance (TCD) of cyst and the pregnant rate within 4 months were followed-up.
RESULTSEffective rate (no fluid cyst sized over 1.0 cm could be found in bilateral ovary and E2 <280 pmol/L) in the treated group was 81.8% (27/33) and 52.0% (13/25) in the control group, showing significant difference between them (P <0.05). Level of E2 decreased in both groups, but the lowering was more significant in the treated group, after 1 month, it being 220.54 +/- 96.23 pmol/L vs 372.56 +/- 330.62 pmol/L (P <0.05). The changes of LH and FSH levels were of no statistical significance (P >0.05). TCD in the treated group was 1.18 +/- 0.46 months, which was shorter than that in the control group (1.96 +/- 1.34 months, P <0.05). The pregnant rate within 4 months in the two groups was 60.6% (20/ 33) and 32.0% (8/25) respectively, showing significant difference (P < 0.05).
CONCLUSIONSJC has good efficacy in treating ovarian cyst after ovulation-induction.

METHODSilicon gel chromatography and HPLC techniques were employed for isolation and purification of the constituents, and the structures were elucidated by various spectral analyses such as NMR, MS and IR.
RESULT5 protostane-type tetracyclic triterpenoids were isolated and identified as 16,23-oxidoalisol B(1), 11-deoxyalisol C(2), alisol F(3), 16beta-methoxyalisol B acetate (4), 16beta-hydroxyalisol B acetate (5).
CONCLUSIONAll of these compounds were found from A. gramineum for the first time.

Aim To investigate the effect of hypercholesterolemia on L-type Ca2+(ICa-L) current and intracellular calcium concentration ([Ca2+]i) in single ventricular myocytes of hypercholesterolemic rats.Methods 12 male wistar rats were randomly divided into two dietary groups:a group fed a normal diet(n=6)and a group fed high-cholesterol diet(n=6) for 4 weeks,respectively. The level of serum lipid was examined.Zymolytic method was used to isolate single ventricular myocytes from hypercholesterolemic and normal rats,which were loaded with Ca2+-sensitive fluorescent indicator Fluo-3/AM.[Ca2+]i represented by fluorescent intensity(FI)was measured by laser scanning confocal microscope.Whole cell patch clamp technique was used to record ICa-L.Results There was no significant influence exhibited on TG level.However, the serum total cholesterol(TC)level of hypercholesterolemic rats was much higher than that of model control group; at the test potential of 0 mV, ICa-L decreased from(-8.56?1.29)pA/pF(Control)to(-5.24?0.90) pA/pF(HC)(n=6 in each group,P

Objective To investigate the changes of T-lymphocyte subsets, NK cells and clinical signification in patients with intestinal tu-berculosis after the treatment of thymosin-al. Methods Sixty-six ca-ses of intestinal tuberculosis patients were treated by thymosin-α1 fol-lowed the basis of conventional anti-TB treatment, while 62 cases as a control group. The frequencies of peripheral blood T-lymphocyte subsets and NK cells were determined by flow cytometry. Results After the end of 12 and 16 weeks, the values of CD3~+ , CD4~+ , CD8~+ , and CD4~+/CD8~+ in trial group exhibited significantly higher than that before treat-ment (P<0.05). NK cells in the end of 8, 12, and 16 weeks showed an ascension too (P < 0. 05). There was no significant difference in the control group after treatment (P > 0. 05). The better clinical efficacy was found in the trial group (P < 0. 05). Conclusion Thymosin-α1 can significantly improve the intestinal immunolologic function in the patient with tuberculosis infection.

Research development of germplasm resources of Salvia miltiorrhiza was reviewed in the aspects of species resource, geographic distribution and varieties, biological characters and culture varieties, and cell and tissue culture. It was suggested that more attention be paid to waters-soluble constituents when evaluating the quality of the medicine, and much more basic studies be done in the course of establishing standard plant base for high quality herb and in the aspect of new variety selection.

OBJECTIVETo investigate the clinical value of real-time tissue elastography (RTE) in the diagnosis of breast cancer.
METHODSOne hundred and twenty patients with breast lumps (135 lesions) were examined with B-mode imaging, color Doppler flowing imaging (CDFI) and RTE. The elastogram was graded using 5-score evaluating method. The postoperative pathological diagnosis was used as gold standard, and the sensitivity, specificity and accuracy of RTE and two-dimensional ultrasonography combined with RTE in diagnosis of breast cancer were calculated.
RESULTWhen the score >4 was set for cut-off criteria of malignancy, the sensitivity, specificity and accuracy of RTE was 85.45%, 83.75% and 84.4%, respectively. While two-dimensional ultrasonography combined with RTE was used, the sensitivity, specificity and accuracy increased up to 100%, 95% and 97%, respectively.
CONCLUSIONRTE combined with two-dimensional ultrasonography can improve the validity in the diagnosis of malignant breast lesions.

To examine the phylogenetic information regarding the gene pool of AIV in domestic ducks in eastern China, the NA genes of twenty-six viruses isolated during 2002-2006, including two H1N1 strains, tenH3N1 strains and fourteen HSN1 strains, which reflected the predominant N1 subtype viruses were subjected to phylogenetic analysis. The results indicated that AIVs of N1 subtype circulating in domestic ducks in eastern China were undergoing a gradual evolution. Analysis of the deduced amino acid sequences revealed that NAs from all isolated H5N1 viruses had a 20-aa deletion in the stalk region (residues 49-68), whereas no deletion was seen in the NAs from other HA subtype viruses. The viruses of H3N1 and H1N1 might have a propensity for reassortment of NA genes, whereas no direct evidence of reassortment of NA gene was obtained in H5N1 viruses.
