Objective:To study the effects of docetaxel, cisplatin and fluorouracil (TPF) regimen simultaneous intensity modulated radiotherapy (IMRT) on immune function and survival prognosis of patients with advanced esophageal cancer.Methods:A total of 93 patients with advanced esophageal cancer were screened in Hebei Veterans General Hospital from June 2015 to December 2017, and were divided into two groups using randomized envelope method. The observation group (47 cases) was given synchronous TPF regimen and IMRT, and the control group (46 cases) was given synchronous PF regimen (cisplatin combined with fluorouracil) and IMRT. Esophageal barium meal, chest and upper abdominal CT were reviewed within 1 month after treatment to assess the short-term efficacy and compare the immune function of the two groups before and after treatment. Kaplan-Meier survival curve was plotted to evaluate the long-term efficacy based on overall survival (OS). The incidence of adverse reactions in the two groups was collected to evaluate their safety.Results:After treatment, the T cell subgroup CD8 + level of the observation group was higher than that of the control group [(33.55±4.46)% vs. (29.06±3.61)%, P<0.05], while CD3 + [(51.29±5.22)% vs. (56.04±6.10)%, P<0.05], CD4 + [(28.27±3.63)% vs. (30.35±3.52)%, P<0.05] and CD4 + /CD8 + (0.84±0.25 vs. 1.04±0.08, P<0.05) levels were lower than those of the control group. The effective rate of recent treatment in the observation group was 82.98% (39/47), while the effective rate in the control group was only 63.04% (29/46), with a statistically significant difference ( χ2=4.70, P=0.030). The median OS of the observation group was 25.3 months (95% CI: 17.9-26.1), and that of the control group was 18.2 months (95% CI: 14.4-25.5), with a statistically significant difference ( χ2=3.28, P=0.038). Adverse reactions during the follow-up period of the two groups of patients were mainly nausea/vomiting, fatigue, anorexia, hematological toxicity, esophagitis and pneumonia, etc., which were mostly grade 1-2, and disappeared after symptomatic treatment or termination of treatment. Compared with the control group, the incidence of nausea/vomiting (46.81% vs. 78.26%, χ2=9.80, P=0.002), anorexia (44.86% vs. 71.74%, χ2=6.99, P=0.008), leukopenia (36.96% vs. 73.91%, χ2=13.37, P<0.001) and esophagitis (61.70% vs. 82.61%, χ2=5.05, P=0.025) adverse reactions was lower in the observation group. Conclusion:TPF combined with IMRT has high efficacy and low adverse reactions, which can be used as an effective treatment to improve the survival prognosis of patients with advanced esophageal cancer.

Objective:
To investigate the effect of glucocorticoid (GC) to cortisol-binding globulin (CBG) expression in rats and the correlation between the changes of CBG levels and the osteonecrosis of the femoral head (ONFH) in rats after GC treatment.
Methods:
A total of 72 healthy adult SD rats were randomly divided into low-dose group and high-dose group by computer random grouping.Thirty-six rats of low-dose group were injected dexamethasone at a dose of 1.5 mg·kg-1·d-1.Thirty-six rats of high-dose group were injected dexamethasone at a dose of 3.0 mg·kg-1·d-1.The blood samples were regularly collected, CBG levels in blood samples were detected by Western-blotting.Rats were killed in batches, femoral head was collected and observed under light microscope after HE staining.The bone lacuna of each group was compared and the ratio of empty lacuna was calculated.Finally, the correlation between the change of CBG level and ONFH was evaluated.
Results:
On the first day after administration, the CBG level of the two groups decreased, and reached the lowest level on the seventh day of administration, and then gradually increased.The reduction of CBG level in the high dose group was greater.With the increase of time after treatment, the number and rate of bone lacuna void in the two groups increased gradually.28 days after treatment, the number of empty bone lacunae and the rate of empty bone lacunae in the low dose group were (6.75±0.42) and (13.98±2.19)%, respectively, which were lower than those in the high dose group[(11.03±0.62) and (21.99±3.17)%,
