Objective To study the clinical significance of dexamethasone (DT) in the combined spinal and epidural anesthesia for delivery of elderly parturient women. Methods 134 elderly parturient women were selected as the research object, and randomly divided into two groups. 69 cases in DT group received intramuscular injection of dexamethasone and combined anesthesia, while 65 cases in INN group received intramuscular injection of tramadol (INN) and combined spinal and epidural anesthesia. The anesthetic effect of the two groups were observed. Results After treatment, the interleukin (IL-6), myeloperoxidase (MPO), tumor necrosis factor-α (TNF-α) and methane dicarboxylic aldehyde (MDA) in DT group were significantly higher than INN group (P<0.05). The five kinds of immunoglobulins levels (IgA, IgD, IgE, IgG and IgM) in DT group were higher than those in INN group (P<0.05). The heart rate (HR) in DT group was lower and mean arterial pressure (MAP) was higher than that in INN group(P<0.05). There was 1 cases of macrosomia, 2 cases of premature delivery in DT group, the adverse pregnancy outcomes was 4.35%(3/69). there was 1 cases of macrosomia, 1 cases of congenital deformity, 1 cases of premature delivery and 1 case of postterm delivery in DT group, the adverse pregnancy outcomes was 5.80%(4/69), with no significant difference between two groups. Conclusion Dexamethasone combined with anesthesia is very effective for delivery of elderly parturient women which shows very good anti-inflammatory and immunoregulation.

Objective To retrospectively analyze the prognostic factors for locoregionally recurrent early?stage extranodal nasal?type natural killer/T?cell lymphoma ( NKTCL) . Methods A total of 56 patients with early?stage extranodal nasal?type NKTCL, who had locoregional recurrence after initial treatment and then received salvage treatment from 1995 to 2014, were enrolled as subjects. The effects of salvage treatment on the overall survival ( OS) rate were analyzed after initial treatment and recurrence. Univariate and multivariate prognostic analyses were performed on the OS rate after recurrence. Results The median follow?up time was 35. 9 months after initial treatment and 14. 8 months after recurrence. The 3?year OS rate was 73% after initial treatment and 58% after recurrence. Compared with chemotherapy alone, radiotherapy?containing salvage treatment significantly improved the OS rates after initial treatment and recurrence ( P=0. 040, 0. 009 ) , and re?irradiation also significantly improved the OS rates after initial treatment and recurrence (P=0. 018, 0. 019). Most (84%) of the acute and late adverse reactions after re?irradiation were grade 1?2 ones. The univariate and multivariate analyses showed that the Karnofsky Performance Status score, radiotherapy in initial treatment, and radiotherapy in salvage treatment were influencing factors for the OS rate after recurrence. Conclusions Radiotherapy achieves improved survival and tolerable toxicities, making it indispensable in the treatment of locoregionally recurrent extranodal nasal?type NKTCL.
