RESUMO
Objective To explore the clinical effect and side-effect of oxaliplatin(L-OHP)-containing regimen and cisplatin (DDP)-containing regimen in TACE of advanced hepatocellular carcinoma (HCC). Methods 108 patients with advanced HCC were randomly divided into experimental group(n=55) and control group (n =53). The experimental group were treated with TACE using L-OHP. After dilute with glucose solution, L-OHP(130 mg/m2) and FT207 (500-750 mg/m2) were injected into blood vessel respectively. ADM (40 mg/m2) and LP (10～30 ml) were emulsified and then used for vessel embolism according to the size of focus. The control group received TACE with DDP, DDP (40 mg/m2) and F]'207(500～750 mg,/m2) were diluted with glucose solution, and also according to the size of tumor' s focus, ADM(40 mg/m2) and LP(10～30 ml) were emulsified for vessel embolism, and then diuretic. Results The total effective rate of experimental group was 67.3 % (37/55), and that of control group was 47.2 % (25/53), and the difference was with statistical significance (P <0.05). The descent rate of AFP of experimental group was 73.1%(31/43), and that of control group was 44.7 % (17/38), and the difference was with statistical significance (P <0.05). The main side effects were gastrointestinal reactions, the incidence rate of nausea and vomiting in experimental group were lower than control group, and the difference was with statistical significance. The incidence rate of leucopenia, damage of hepatic function and peripheral neuritis were not significant. Damage of heart and kidney were not found in the two sets. Conclusion L-OHP -containing regimen in TACE of advanced HCC is an efficient method, with good security and good tolerance to patients.
RESUMO
Objective: To investigate the relationship between chemosensitivity to L-OHP and expressions of multidrug resistance (MDR) associated factors in lymph node metastases (LNMs) of gastric carcinoma. Methods: The chemosensitivity to L-OHP was measured by MIT assay, and the expressions of P-gp, GST-π, P53, Survivin and Bcl-2 were determined by immunohistochemistry in 54 paired primary tumor (PT) and LNMs of gastric carcinoma. Results: The inhibition rates of LNMs cells for L-OHP were lower than those of PT (P<0.05). The expressions of P-gp, GST-π and Bcl-2 were higher in LNMs than in PT (P<0.05), and no signifi-cant difference was found in the expression of P53 and Survivin between LNMs and PT (P>0.05). Positive cor-relations among P-gp, P53 and Bcl-2 were found in PT and LNMs (r=0.3424, 0.7123, 0.4548, P<0.05). There was no significant difference in the expression of GST-π and Survivin between PT and LNMs (P>0.05). There was statistically negative correlation between inhibition rates and expression of P-gp, GST-π, and Survivin in PT (P<0.05). In LNMs, only Survivin was negatively correlated with inhibition rates of L-OHP (P<0.05). Conclu-sion: The LNMs of gastric carcinoma are heterogeneous with PT in respect to chemosensitivity to L-OHP and expression of multidrug resistance associated factors. The main factors that affect chemosensitivity to L-OHP are also significantly different between PT and LNMs. Effective adjuvant chemotherapy after surgery and re-version to multidrug resistance (MDR) of gastric carcinoma depend on targeting the metastatic lesions of gas-tric carcinoma.
RESUMO
Objective:To study the effects of Astragalus Root Injection(a traditional Chinese herb medicine) on oxaliplatin-induced apoptosis of hippocampal neurons. Motheds: The primary culture of hippocampus neurons from SD rats (aged within 24h) were treated with different concentrations of oxaliplatin( L-OHP) (0, 3, 5 and 10 ?g/mL) and Astragalus Root Injection (0.05, 0.2 and 0.5 g/mL). The apoptosis of the neurons and the nerve growth factor(NGF)level were analyzed. Results: Astragalus Root Injection dose-dependently decreased neuronal cell apoptosis induced by oxaliplatin (P
