Objective To study the efficacy of radiotherapy combined with cisplatin and 5-fluorouraci concurrent chemoradiotherapy on locally advanced esophageal carcinoma. Methods 80 cases with locally advanced esophageal carcinoma collected in our hospital from September 2002 to December 2011 were divided into combination group and radiotherapy group, each had 40 cases. Patients of combination group were given radiotherapy combined with DDP and 5-FU, while radiotherapy group were only adopted radiation therapy. The efifcacy and the safety of the therapy methods were evaluated. Results The treatment effect of the chemoradiotherapy on locally advanced esophageal carcinoma was obvious. The efifcacy of combination group was 90.0%, and radiotherapy was only 72.5%, the difference was signiifcant(P<0.01). The survival rate of combination group was 33%, higher than 24.4%of radiotherapy group. The adverse reactions of combination group were higher than radiotherapy group, but most of which were light, and could be eliminated after active treatment. Conclusion The radiotherapy combined with DDP and 5-FU can enhance the efifcacy and survival rate of patients with locally advanced esophageal carcinoma, and also cause an increase in adverse reactions, which can be controlled effectively.

Objective To establish the method of testing immunoglobulin G (IgG) with Fc sialylation, and to investigate the clinical significance of IgG with Fc sialylation in systemic lupus erythematosus (SLE), especially in those with neuropsychiatric manifestations (NPSLE). Methods Seventy-five SLE including thirty patients with neuropsychiatric manifestations (NPSLE) and forty-five non-NPSLE patients, 30 rheuma-toid arthritis (RA) patients, 32 juvenile idiopathic arthritis (JIA) patients and 41 healthy controls were recruited in this study. Standard method of testing lgG with Fc sialylation was established by a lectin based sandwiched enzyme linked immunosorbent assay (ELISA). The levels of IgG with Fc sailylation were assayed, and its clinical significance was evaluated. Results There were no difference in the levels of serum IgG with Fc sailylation in RA group (0.82±1.81) mg/ml, JIA group (0.69±1.30) mg/ml, healthy control group (0.64± 1.09) mg/ml, and the levels of IgG with Fc sailylation in SLE group (0.12±0.17) mg/ml (P<0.01), especially in NPSLE group [(0.03±0.03) mg/ml, P<0.01] was significantly lower than that of control groups. The perc-entage of IgG with Fc sialylation in control group (4.64±5.90)% were significantly higher than that in non-NPSLE (1.88±2.16)% (P<0.01) and in NPSLE (0.29±0.47)% (P<0.01). The percentage of IgG with Fc sial-ylation was negatively associated with SLEDAI score (r=-0.43, P<0.01). Conclusion Significantly low level of serum IgG with Fc sialylation was associated with disease activity in SLE patients, especially in NPSLE patients, lgG with Fc sialylation may be a new target for therapeutic strategy.
