RESUMO
Objective To analyze the effect of TSH inhibition on soluble interleukin 2 receptor ( sIL-2R), interleukin 44 variant 6 (CD44V6), tumor specific growth factor (TSGF) and T lymphocyte subsets in elderly patients with thyroid cancer.Methods 50 elderly patients with thyroid cancer in our hospital were collected.The patients were randomly assigned to experimental and control groups, 25 cases in each group, patients in the experimental group were given TSH suppression therapy after surgery , patients in control group were given thyroxine replacement therapy after operation, treatment for 1 month, serum SIL-2R, CD44v6, TSGF and peripheral blood T lymphocyte subsets situation were detected in all patients with .ResuIts After treatment, compared with the control group, ①in the experimental group, the level of serum sIL-2R was significantly lower, the difference was statistically significant(P<0.05);②the serum CD44V6 level was lower in the experimental group (P<0.05);③the serum TSGF level was lower in the experimental group (P<0.05);③in the experimental group,the levels of CD3 + and CD4 +were higher, levels of CD8 + were lower ( P<0.05 ) .ConcIusions TSH suppression therapy can reduce senile thyroid cancer patients serum SIL-2R, CD44v6, TSGF and CD8 +lymphocyte level, peripheral blood T lymphocyte CD3 +, CD4 +levels were elevated,and improve the immune function of patients , the clinical has guiding significance .
RESUMO
Objective To investigate the serum levels of PGⅠ,PGⅡ,TK1,TSGF and CEA,CA724 in gastric cancer and eval-uate the application value of combined detection the above tumor markers in diagnosis of gastric cancer.Methods The serum levels of TSGF were measured in 94 patients with gastric cancer and 85 healthy control by rate method.PGⅠ,PGⅡ,TK1 and CEA,CA724 were detected by electrochemiluminescence method.Results PGⅠand PGⅠ/PGⅡwere lower than healthy control in serum of patients with gastric cancer (both P0.05),and other tumor markers were all higher than healthy control (all P<0.05).The sensitivity of PGⅠ,PGⅠ/PGⅡ were better than TK1,CEA and CA724 (all P<0.05),the specificity of PGⅠ/PGⅡ,CEA were better than TSGF (both P<0.05),the accuracy of PGⅠ,PGⅠ/PGⅡ were better than CA724 and TSGF alone (all P<0.05).When combined TSGF,TK1 and PGⅠ/PGⅡ,PGⅠ,the sensitivity was better than combined PGⅠ/PGⅡand PGⅠ alone (P<0.05).Then when added CEA, CA724,this sensitivity improved up to 82.98%.Although the combined detection would show a lower specificity,it still keep high to 84.71%.Combined detection improved the accuracy in diagnosis of gastric cancer,up to 83.80%.In this re-search,There was no difference in sensitivity,specificity and accuracy between the group of PGⅠ+PGⅠ/PGⅡ+TSGF+TK1+CEA and the group of PGⅠ+PGⅠ/PGⅡ+TSGF+TK1+CEA+CA724.Conclusion Compared with CEA and CA724 popular used in clinic,PGⅠ/PGⅡand PGⅠshowed a better application value.The group of PGⅠ+PGⅠ/PGⅡ+TSGF+TK1+CEA showed the best sensitivity.Combined detection of serum levels of PGⅠ,PGⅠ/PGⅡ,TSGF,TK1 ,CEA can significantly raise the sensitivity and accuracy in diagnosis of gastric cancer.
RESUMO
Objective To explore the clinical value of squamous cell carcinoma associated antigen (SCC) and tumor specific growth factor (TSGF) in cervical carcinoma. diagnose. Methods The serum samples of SCC and TSGF were collected from 40 health volunteers, 56 cervical intraepithelial neoplasia (CIN) patients and 101 squamous cell cervical cancer patients. SCC and TSGF amount were measured by MEIA and biochemistry olorimetry method respectively, and were compared. Results The mean level of serum SCC and TSGF in the cervical cancer group was (6.95 ± 1.23) ng/mL and (81.0 ± 16.3)U/mL respectively, significantly higher than that in the CIN group and control group. The sensitivity and accuracy of combining SCC with TSGF in diagnosing cervical carcinoma were 91.1%and 87.4% respectively, both higher than allying SCC or TSGF alone. Conclusions SCC and TSGF levels are helpful in the diagnosis of cervix carcinoma. The combined determination can improve the sensitivity and accuracy of cervical carcinoma diagnose.
RESUMO
Objective To study the regulatory effect of paclitaxel injection on vascular endothelial related factors in serum of uterine cancer patients.Methods 30 cases of uterine cancer patients treated with paclitaxel (observation group)and 30 cases of uterine cancer patients treated with surgery (control group)were selected.Chemiluminescence immunoassay (CLIA)was used to detect expressions of serum tumor necrosis factor(TNF), Interleukin-8(IL-8)and tumor specific growth factor (TSGF).Results Before treatment,there was no significant difference between the serum TNF, IL-8 and TSGF in observation group and control group(P<0.05).At 3 months after treatment,the serum TNF,IL-8 and TSGFwere significantly lower than before treatment ,which was statistically significant(P<0.05).Conclusion Paclitaxel can decrease serum TNF,IL-8 and TSGF in patients with uterine cancer,which provides a new theoretical basis for its anticancer effects.
RESUMO
Objective:To explore the value of tumor specific growth factor (TSGF) and combined tumor markers (AFP,CEA,Ft,TSA) in the diagnosis of malignant tumor.Methods:TSGF was measured by chemical method and combined tumor markers by chemical method and ELISA method.The results in 170 cases with malignant tumors and 60 cases with non-tumor patients were analyzed.Results:In cases of single TSGF measurement,the positive rate was 82% in liver carcinoma,87% in lung cancer,and 86% in carcinoma of stomach,colon,or rectum.The positivity rate of TSGF plus combined tumor marker determination was 97.5%,97.7%,and 97.5% respectively.Conclusion:TSGF plus combined tumor marker determination improve the positivity rate for tumor diagnosis,provide evidence for localization,and promote early diagnosis.
