China Pharmacy 2005;0(24):-
OBJECTIVE: To study the links between chronic pyelonephritis (CPN) and immune function, and the action mechanism of Yishenkang granule on CPN. METHODS: A total of 120 CPN cases were randomly assigned to Yishenkang granule group, Sanjing tablet group and western medicine group, which were compared with healthy control group. The levels of the peripheral blood T lymphocyte subsets, serum immunoglobulin, complement, secretory IgA in urine and the cell factor IL-2 in CPN cases before and after treatment were detected by monoclonal antibody method, agar diffusion method, radioimmunoassay, radioimmune balancing method and compared with those in healthy control group. RESULTS: In CPN cases compared with healthy control group, the levels of serum immunoglobulin, complement, secretory IgA in urine were significantly lower while the level of cell factor IL-2 were significnatly higher (P

Objective To analyze the effect of combined detection of serum tumor markers, Ki-67 and P-glycoprotein (PGP) in lymph node metastasis and postoperative recurrence of colorectal cancerpatients. Methods The clinical data of 517 colorectal cancer patients who had underwent surgicaltreatment were retrospectively analyzed. Among them, lymph node metastasis was found in 165 cases(lymph metastasis group), and 352 cases did not have lymph node metastasis (non lymphoid metastasis);postoperative recurrence was found in 224 cases (postoperative recurrence group), and 293 cases did havepostoperative recurrence (non postoperative recurrence group). The serum tumor markers levels of cancerantigen 19- 9 (CA19- 9), carcinoembryonic antigen (CEA), cancer antigen 125 (CA125) and theexpressions of Ki-67, PGP were compared. The correlation between the serum tumor markers levels andthe expressions of Ki-67, PGP was analyzed. Results The serum levels of CEA, CA19-9 and CA125 and the positive expression rates of Ki-67 and PGP in lymph metastasis group were significantly higher than those in non lymph metastasis group:(21.39 ± 3.15)μg/L vs. (10.12 ± 2.48)μg/L, (68.48 ± 5.82) U/L vs. (35.26 ± 3.51) U/L, (82.16 ± 7.53) U/L vs. (32.46 ± 6.24) U/L, 69.70% (115/165) vs. 13.64% (48/352) and 72.73%(120/165) vs. 14.77%(52/352), and there were statistical differences (P<0.01). The serum levels of CEA, CA19-9 and CA125 and the positive expression rates of Ki-67 and PGP in postoperative recurrence group were significantly higher than those in non postoperative recurrence group:(18.26 ± 2.34)μg/L vs. (9.18 ± 1.26)μg/L, (47.52 ± 4.85) U/L vs. (21.43 ± 2.18) U/L, (59.16 ± 4.25) U/L vs. (33.17 ± 3.46) U/L, 60.27% (135/224) vs. 9.56% (28/293) and 6.70% (15/224) vs. 7.51% (22/293), and there were statistical differences (P<0.01). The correlation analysis results showed that the positive expression rates of Ki-67 and PGP were positive correlated with the serum levels of CEA, CA19-9 and CA125 (P<0.05). Conclusions The levels of serum tumor markers and the positive expression rates of PGP and Ki-67 in colorectal cancer patients with lymph metastasis and postoperative recurrence are high. The levels of tumor markers are closely related to the positive expression rates of Ki-67 and PGP, which indicates that the combined detection of these indexes has a good effect on evaluating lymph metastasis and postoperative recurrence of colorectal cancer patients.

Objective The TCS gene without N-and C-terminal sequences was cloned into pET-29b in order to get the recombinant trichosanthin(rTCS) at the relatively high level in E.coli,and the rTCS immunogenicity was compared with natural TCS(nTCS). Methods TCS gene without the N-and C-terminal coding sequences was amplified by RT-PCR,and then inserted into pET-29b.The soluble rTCS was induced with IPTG and purified through metal chelate affinity chromatography,the purity and content were showed by the thin-layer scan analysis and bradford assay.After the rabbits were immunized with purified rTCS and nTCS,respectively,the titer and specificity of polyclonal antibody were detected by indirect ELISA assay and Western blotting. Results 1.The vector pET-29b-TCS was constructed successfully after it was confirmed with the same restriction enzymes.2.The rTCS attained the maximum in the presence of 1 mmol/L IPTG for 4?h at 30℃.3.The soluble rTCS was expressed at relatively high level(36% of total protein in E.coli) and the yield of rTCS with a purity of 95% was 1.2?g in 1 L bacterium.4.The polyclonal antisera titer of nTCS was significantly higher than that of rTCS(1∶40?960 and 1∶5?120 respectively).5.The specific reaction between rTCS and anti-nTCS antibody was detected by Western blotting.Conclusion The high level expressing vector pET-29b-TCS,carrying TCS gene withoug the N-and C-terminal coding sequences,was constructed successfully.The immunogenicity of rTCS was remarkably lower than that of nTCS,which indicates that glycosylation of nTCS has a relationship with the antigenicity.
