Objective To observe the changes of specific proteins in serum of acute stage patients with SARS and its clinical application. Methods The acute stage patients with SARS group included 42 cases who had clinical symptoms less than five days. In normal group: 30 healthy adults were as controls. Tests for specific proteins were immunoglobin G ( IgG ) , immunoglobin A ( IgA) , immunoglobin M ( IgM) , complement C3( C3),complement C4(C4),C-reaction protein (CRP), al acid glycoprotein( a1-AG) , a1 antitrypsin(a1-AT) ,transferrin(TRF), ceruloplasmin( CER) in sera by Ratenephelometer. Results The level of CRP, a1-AG, a1-AT in sera of patients with SARS were higher than that in control group ( P 0. 05). Conclusion It suggested that specific proteins in serum of acute stage patients with SARS change in a particular way. There were some help for the diagnosis of the phlogistic degree of acute stage patients with SARS by detecting CRP, a1-AG and TRF simultaneously.

Tumor 2008;28(12):1102-1105
Objectives: To evaluate the safety and efficacy of CT-guided iodine 125 seed implantation combined with gemcitabine and 5-fluorouracil (5-FU)-based intra-arterial perfusion in the treatment of patients with advanced pancreatic cancer. Methods: A total of 16 patients with advanced unresectable pancreatic cancer underwent CT-guided iodine implantation combined with gemcitabine plus 5-FU-based intra-arterial perfusion. One week after implantation of iodine 125 seeds, all the patients received concurrent intra-arterial infusion of gemcitabine and 5-FU, which was repeated for 3 to 4 cycles. Three patients complicated with liver metastasis were given additional arterial embolization concurrently. Survival period, pain-relieving period, and adverse reaction of patients were observed. Results: All the patients were followed up for 2-25 months. CT scan found that there were 2 cases with complete response, 9 cases with partial response, 3 cases with stable disease, and 2 cases with progressive disease after 2 months of follow-up. The overall effective rate (CR + PR) was 68.8%. The median survival period for all enrolled patients was 11 months. It was 15 months for patients at stage II + III and 9 months for those at stage IV. No serious complications including gastrointestinal bleeding, pancreatitis, pancreatic fistula and radiation colitis were observed. Conclusion: CT-guided iodine 125 seed implantation combined with gemcitabine and 5-fluorouracil (5-FU)-based intra-arterial perfusion has better palliative pain-relieving effects. It has safe and effective effects in short terms and causes less complications in the treatment of advanced pancreatic cancer patients.
5. Expressions of P-gp, ToPo II α, GST-π and c-erbB2 in endometrial cancer and their significance
Tumor 2008;28(11):968-971
Objective: To investigate the expressions of P-glycoprotein (P-gp), topoisomerase II alpha (ToPo II α), glutathione-S-transferase-pi (GST-π), and oncogene c-erbB2 in endometrial cancer and their significance. Methods: Immunohistochemistry SP method was used to determine the expressions of P-gp, ToPo II α, GST-π and c-erbB2 in 127 tumor samples from patients with endometrial cancer. Results: Among 127 tumor samples from patients with endometrial cancer, the positive expression rates of P-gp, ToPo II α, GST-π and c-erbB2 were 63.0%, 44.9%, 70.1%, and 47.2%, respectively. The co-expression rate of P-gp and GST-π was 50.7%. The expression levels of P-gp, GST-π and c-erbB2 in poor differentiation endometrial cancer were significantly higher than those in well/moderate differentiation endometrial cancer (P < 0.05). While the expression level of ToPo II α in well/moderate differentiation endometrial cancer was significantly higher than that in poor differentiation endometrial cancer (P < 0.05). Univariate analysis indicated that the expression of P-gp, GST-π and c-erbB2 were associated with the survival time and poor prognosis of endometrial cancer patients. COX regression analysis suggested that the expression of P-gp and co-expression of P-gp and GST-π correlated with the survival rate of patients. Over-expression of ToPo II α tended to have protective effects on patients. Conclusion: Multidrug resistance-associated protein (MRP), GST-π, Topo II α, and lung resistance protein (LRP) plays important roles in the multidrug resistance(MDR) of tumor chemotherapy. Combined effects of the four multiple factors, P-gp, ToPo II α, GST-π and c-erbB2 were the main action mechanism for the MDR of endometrial cancer. It has an important guiding significance for predicting the prognosis and making rational chemotherapeutic regimens for patients with endometrial cancer.

Aim The current study was conducted to investigate the effect of GSTP1 codon 105 polymorphism, alone and in combination with GSTM1-deletion polymorphism, on erythrocyte GST activity in 196 Han Chinese. Methods GST activity was measured in healthy Chinese by a spectrophotometric method (n=196;101 males and 95 females; age range 21~81 years; median 43.5 years). GSTM1 polymorphisms were analyzed by a PCR-Multiplex procedure, whereas GSTP1 polymorphism was analyzed by PCR-RFLP. Results The frequency of GSTM1 null genotype was 56.1% and the frequency of I/I, I/V, and V/V genotypes was 60.7%, 35.2% and 4.1%, respectively, in Han Chinese. The mean erythrocyte GST enzyme activity for I/V genotype group(3.53?0.63 U?g -1Hb) was significantly lower than that for I/I genotypes (4.25?1.07 U?g -1Hb, P=0.000), while significantly higher than that for V/V genotypes (2.44?0.67 U?g -1Hb, P=0.004). In GSTM1(-) group, the GST activity of carriers of GSTM1(-)/GSTP1- I/I is significantly higher than that of GSTM1(-)/GSTP1- I/V or-V/V, however, in GSTM1(+) group, there is no difference between different subgroups. There was no significant difference in the mean GST activity among different age groups. Erythrocyte GST activities were significantly higher in females than in males, but not significantly. Conclusion The GST activity measured by CDNB-based assay is probably strongly correlated with the GSTP1 105Val genotype, although other GST enzymes would tend to dilute the GSTP1 genotype effect.
