Objective To evaluate the prognostic value of iASPP for nasopharyngeal carcinoma (NPC).Methods One hundred and thirty patients with nasopharyngeal carcinoma were initially diagnosed and treated between January and December 2012 in Department of Radiation Oncology of the First Affiliated Hospital of Guangxi Medical University.The clinical staging was classified according to the cancer staging criteria 2009 AJCC/UICC.All patients were treated by IMRT.Cisplatin-based concurrent chemotherapy was given to patients with stages Ⅲ-ⅣB disease.Immunohistochemistry was used to detect the expression of iASPP in the carcinoma tissues,and the clinicopathological features were compared among the patients with different expressions of iASPP.Furthermore,the relationship between the expression of iASPP and the efficacy in patients was explored.Results Of 130 patients,positive expression of iASPP was observed in 86 patients (66.2％),and negative expression in 44 patients (33.8％).There was significant difference in the positive expression rate of iASPP among the patients with different N-stage and clinical stages(x2 =7.565,4.947,P ＜ 0.01).At three months after treatment,no significant difference was found in the response rate of tumor with different expression of iASPP.In univariate analysis,the expression of iASPP was significant predictor of 3 year-DMFS (x2 =4.335,P =0.037) and PFS (x2 =6.640,P =0.01).Furthermore,N-stage was significant predictor of 3y-DMFS (x2 =8.058,P =0.005),PFS (x2 =9.554,P =0.002) and OS (x2 =6.987,P =0.008),respectively.By using multivariate Cox analysis,the expression of iASPP and N-stage was independent prognostic factors for PFS (x2 =4.336,5.228,P ＜ 0.05),respectively.Conclusions Positive expression of iASPP may be a poor prognostic factor for NPC patients.

Objective To study the epidemiological and clinical characteristics of patients with severe acute respiratory syndrome(SARA). Methods Clinical data from 682 patients with SARS were retrospectively analyzed. Results The patients ranged from 13 to 76 years old, 387 male and 295 female. A total of 356 patients (52.2) had a history of close contact with diagnosed SARS patients, and 113 (25.1%) had been to hospital ever. The most common symptom was fever (99.3%), followed by cough (44.4%), shortness of breath (12.2% ), diarrhea (8.9%). 596 patients (87.4%) had normal or decreased white blood cell counts. Serum ALT and CPK levels were elevated in 112 patients (16.4%)and 17 patients (2.5%) respectively. Infiltrates on chest radiography were seen in all patients, with 69.8% involved both lungs. Six patients (0.9%) died of SARS. Conclusion SARS is infectious. Hospital is an important place where SARS transmits. Fever, cough and infiltrative changes on chest radiography are mainly symptoms and signs.

Objective:To evaluate the clinical value of radioactive nuclide strontium chloride (89SrCl2) combined with 99Tc-MDP in treating patients with breast cancer and osseous metastasis. Methods:A total of 80 patients with breast cancer and experiencing bone pain from osseous metastasis were randomly categorized into three groups. 22 patients were treated with 99Tc-MDP (99Tc-MDP group), 30 were treated with 89SrCl2 (89SrCl2 group), and 28 were treated with the combination therapy of 89SrCl2 and 99Tc-MDP (combination group). The analgesic effect, remission of bone metastases, and quality of life of patients in the three groups were observed before and after treatment. Side effect was also monitored. Results:In the combination group, the overall pain relief rate and the increase rate of life quality score were 92.9%(26/28) and 78.6%(22/28), respectively. The combination group was statistically significantly different from the two single-treatment groups (P<0.05). The effective rate of metastatic lesions was 46.4%(13/28) in the combination group, which was significantly higher than that in the 99Tc-MDP group (18.2%, 4/22;P<0.05). The effective rate of metastatic lesions was not significantly different between the combination and 89SrCl2 groups (33.3%, 10/30) (P>0.05). Conclusion:The treatment of 89SrCl2 com-bined with 99Tc-MDP can increase the analgesic effect and significantly improve the curative effect without overt side effects in patients with breast cancer and bone metastasis.

Objective To study the expression and change of neuropeptide substance P (SP) during the wound healing of deep partial thickness scalding in diabetic rats. Methods Eighty-four Wistar rats were randomly divided into diabetes mellitus group (n=42) and control group (n=42). Diabetic rat models were established by intraperitoneal injection of streptozotocin (STZ) in diabetes mellitus group, and those in control group were intraperitoneally injected with aseptic citrate buffer solution. Deep partial thickness scalding with diameter of 2 cm on the back were prepared in all the rats. The pre-scalding and post-scalding wound specimens of different time points were obtained, and the percentages of wound closure were calculated. The wound specimens were also obtained for immunohistological staining to compare the areas with positive staining of SP, and ELISA was employed to detect the expression of SP in the wound tissues. Results The percentage of wound closure was significantly lower in diabetes mellitus group than that in control group from 7 days post-scalding (P< 0.01). The areas with positive staining of SP in diabetes mellitus group were much smaller than those in control group at different time points, which was most significant on the seventh day post-scalding[(1 350.93±99.28) μm2 vs(1 715.86± 103.41) μm2](P < 0.01). The expression of SP in the wound tissues was significantly lower in diabetes mellitus group than that in control group at different time points, which was most significant on the seventh day post-scalding[(114.04±9.96) vs(143.39±8.94)](P<0.01). Conclusion The significantly lower expression of SP in wound site may be one of the causes of delayed wound healing in diabetic rats.

Objective·To investigate effect and the possible molecular mechanism of JQ1,a specific inhibitor of bromodomain containing protein 4,on human hypertropic scar.Methods·Primary fibroblasts were isolated from human hypertrophic scars and treated with JQ-1 of different concentrations (0.1,0.5,1.0,2.0,2.5,and 12.5μmol/L) for 48 h.Then CCK-8 kit and wound healing assay were used to measure proliferation and migration of the fibroblasts.ELISA was adopted to detect the levels of collagen type Ⅰ (COL Ⅰ) and TGF-β1 after JQ-1 treatment for 24 h.Thirty-six nude mice were used for hypertrophic scar models.Human hypertrophic scars (1.0 cm× 1.0 cm×0.5 cm) were grafted subcutaneously at the backs of nude mice to establish scar animal models.After 4 weeks,the nude mice were averagely divided into two groups,i.e.JQ-1 group and DMSO group,which were respectively injected with 0.5 μmol/L JQ-1 and 0.1％ DMSO each mouse every day.COL Ⅰ / Ⅲ and α-smooth muscle actin (α-SMA) were examined by immunohistochemical method and sirius red staining.Results·Cell experiments showed that JQ-1 with the concentration of 0.5 μmol/L and above significantly inhibited proliferation of fibroblasts (P＜0.01).JQ-1 inhibited migration of fibroblast (P＜0.01).JQ-1 inhibited secretion of COL Ⅰ and TGF-β1 of fibroblasts (P＜0.01).Animal experiments showed that concentration and proportion of COL Ⅰ / Ⅲ in JQ-1 group decreased compared to DMSO group (P＜0.05).α-SMA protein expression in JQ-1 group also decreased (P＜0.05).Conclusion·JQ-1 can inhibit proliferation,migration,secretion of COL Ⅰ,and production of TGF-β1 of human sear fibroblasts in vitro;it can also inhibit secretion of COL Ⅰ /Ⅲ and fibroblast-myofibroblast differentiation in the human hypertrophic scars in nude mice.

Objective To observe the long-term clinical effects of Fogarty catheter on arteriovenous fistula thrombosis and reperfusion rate in patients on hemodialysis. Methods The thrombosed vascular access was incised and F4 or F5 Fogarty catheter was inserted. After the Fogarty catheter passed through the thrombus, the heparin saline was infused into the balloon and then the catheter was pulled back. All the patients were followed up for 5-48 months. Results In 14 cases of total 15 patients embolisms were removed successfully and the blood flow during hemodialysis reached more than 200 ml/min. The catheter use time was (21.5±15.4) months in average and the longest use time was 48 months. Conclusions The recent and long-term effects of Fogarty catheter is good for arteriovenous fistula thrombosis, which prolongs the use period of autologous arteriovenous fistula and is worthy to be popularized.
