Radiotherapy is one of the most important treatments for glioma; however its therapeutic effect is unsatisfying. Timing, accurate target outlining, a total dose higher than 60Gy, conformal modulating radiotherapy and combined chemotherapy and targeted therapy are important factors in improving the outcome of radiotherapy.

This study was aimed to investigate the effects of resveratrol on plasma glucose and the oxidative stress ability in gestational diabetic rats. A total of 100 SD rats with gestation for 5 days were intraperitoneally injected with streptozotocin (STZ, 35 mg?kg-1) to prepare gestational diabetic rat model. Rats were randomly divided into 6 groups, which were the normal gestation group, gestational diabetic model group, resveratrol (30, 60, 120 and 240 mg?kg-1) treatment groups, with 20 rats in each group. A total of 20 rats with gestation for 5 days were selected as the normal gestation control group and another 20 rats with no gestation were selected as the normal control group. The levels of plasma glucose and insulin were determined on 0, 7, 14 days after experiment. Two weeks later, the contents of malondialdehyde (MDA) and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) in serum were determined. The results showed that compared with the normal control group, there were no significant difference on the levels of plasma glucose and insulin, the content of MDA, and the activities of SOD, GSH-Px and CAT of the normal gestation control group (P > 0.05). Compared with the gestational diabetic model group, the content of MDA in serum of the resveratrol (30, 60, 120 and 240 mg?kg-1) treatment groups were significantly decreased (P < 0.05,P < 0.01); the level of plasma glucose were significantly decreased and the level of insulin was significantly increased of the resveratrol (120 and 240 mg?kg-1) treatment groups (P < 0.05,P < 0.01); the activities of SOD, GSH-Px and CAT were also significantly increased (P < 0.05, P < 0.01). It was concluded that resveratrol had dose-dependent effect on reducing plasma glucose and improving antioxidant ability in gestational diabetic rats, which perhaps related to its effects on raising the level of insulin and improving the activity of antioxidant enzymes.

Objective:To investigate the effect of arterial baroreflex(ABR)on survival rate of rats with cecal ligation and puncture(CLP)-induced sepsis.Methods:Male Sprague-Dawley rats were divided into 2 groups:sham-operated rats(n=22)and sinoaortic denervated(SAD)rats(n=22).Four weeks after SAD rats were subjected to CLP-induced sepsis,the blood pressure and heart period(HP)were monitored for 12 hours in conscious state and the survival of rats was observed.Results:Both the diastolic and systolic blood pressue gradually decreased after CLP;the HP shortened first and then drastically prolonged until the death of rats.At 12 h after CLP the survival rate of SAD rats was lower than that of the sham-operated rats(59% vs 86%).Significant differences were found between the Kaplan-Meier survival curves of the rats in 2 groups(P

Objective To investigate the comprehensive prevention strategy in the prevention of oral mucositis (OM) during allogeneic hematopoietic stem cell transplantation (HSCT). Methods A total of 721 patients who received HSCT from January 2010 to December 2011 at the Institute of Hematology, Peking University were enrolled. All the patients received the comprehensive prevention strategy of OM. Results A total of 315 patients (43.7 percents) suffered from OM during HSCT, the median time from HSCT to OM occurrence was 5 days. There were 173 (54.9 percents), 91(28.9 percents), 37(11.7 percents), and 14(4.4 percents) patients suffered from gradeⅠ,Ⅱ,Ⅲ, and IV OM, respectively. Tongue OM was most common. A total of 111 patients suffered from multiple OM (≥2 locations). Multiplicity showed that duration of agranulocytosis≥15 days was the only independent risk factor of OM in HSCT [ hazard ratio (HR) value 1.5, P<0.05 ]. Neutrophil engraftment time≥12 days was significantly associated with prolonged OM (≥8 days) (HR=2.1, P<0.05). Patient age ≥20 was independent risk factor for occurrance of grade Ⅲ-Ⅳ OM (HR=2.7, P<0.05). Conclusions Comprehensive prevention strategy can overcome the risk factors of OM and prevent the occurrence of OM during HSCT.

Objective To evaluate the prognostic value of the expression of epidermal growth factor receptor (EGFR) and nm23 in patients with nasopharyngeal carcinoma (NPC). Methods From 2003 to 2006, 127 NPC patients who had undergone biopsy before radiotherapy were reviewed retrospectively. All patients received intensity-modulated radiotherapy using 6 MV X-rays combined with platinum-based chemotherapy. Immunohistochemistry SP method was adopted to detect the expression of EGFR and nm23 in NPC biopsy specimens . The relationship between the expression of EGFR and nm23 and survival was analyzed. Results The positive rate of EGFR and nm23 were 80.3% and 47. 2% respectively. The nm23expression was correlated with distant metastasis (χ2=7.03, P = 0. 008 ). The 5-year estimated local control, over-all survival (OS) and disease-free survival (DFS) were 58.3% ,53.5% and 46. 5%. Patients with negative expression of EGFR had a significantly better 5-year OS, DFS (χ2=8.23, P=0.004;χ2=5.25,P=0.022) than those with positive expression. Patients with positive expression of nm23 had a significantly higher 5-year OS (χ2=15.68, P = 0. 000) and DFS (χ2=14. 85, P = 0. 000) than those with negative expression. The clinical stage, EGFR and nm23 expression were independent prognostic factors shown by Cox proportional hazard model (χ2=23.03, 18.33, 39.92, P= 0.000, 0.000, 0.000).Conclusions The EFGR and nm23 expression were correlated with the prognosis in NPC patients.

Objective To evaluate the treatment outcomes and toxicities of intensity-modulated radiation therapy (IMRT) combined with chemotherapy for children and adolescents with nasopharyngeal carcinoma.Methods Forty-three nasopharyngeal carcinoma patients less than 19 years old were recruited between April 2010 and April 2016.All patients were treated with IMRT (total dose 61.2-76 Gy) combined with cisplatin based chemotherapy.The Kaplan-Meier test was used to calculate overall survival (OS) and progression-free survival (PFS).The patient's clinical characteristics,side effects and longterm effects of treatment were retrospectively analyzed.Results Among 43 patients,there were 29 (67.4％) male and 14 (32.6％) female,and the median age was 14 years old (range,6-18 years).According to AJCC 7thstaging system,2 patients were in stage Ⅱ,26 in stage Ⅲ,7 in stage ⅣA and 8 in stage Ⅳ B.All patients were confirmed as non-keratinizing carcinoma.The positive rates of EB virus VCAIgA was 53.8％ (7/13),and Rta-IgG was 60.0％ (6/10) before treatment.The median radiation dose was 70 Gy (range,61.2-76 Gy) to the primary tumor.Thirty-three (76.7％) patients received neoadjuvant chemotherapy,with 20 (46.5％) and 36 (83.7％) patients treated by concurrent and adjuvant chemotherapy,respectively.With a median follow-up of 24 months (range,3-76 months),the 5-year OS and PFS ratios were 75.3％ and 64.7％,respectively.There were 5 patients (11.6％) occurred to bone metastasis within 2 years after treatment.Hypothyroidism was reported in 47.4％ (9/19) patients after IMRT.Conclusions Nasopharyngeal carcinoma in childhood and adolescence is mostly locally advanced diseases with poor differentiation.IMRT combined with chemotherapy produce a well treatment outcome with good tolerance in children and adolescents patients.The most common treatment failure bone metastasis.Radiation-induced hypothyroidism is common.
