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 explore the relationship between myocardial glucose metabolism in the right heart and cardiac function in patients with idiopathic dilated cardiomyopathy (IDCM).Methods From October 2010 to May 2013,64 consecutive patients (45 males,19 females; mean age:(53 ± 12) years) with IDCM were enrolled in this study.All patients underwent 18F-FDG myocardial PET imaging,late-gadolinium enhancement cardiac MRI (cMRI-LGE) and UCG.TrueD software was used to determine the SUVmax in right (SUV-R) and left (SUV-L) ventricular free wall,and the ratio of SUV-R to SUV-L (SUV-R/L) was calculated.The cMRI-LGE was used to evaluate LVEF,RVEF and LGE in left heart.Pulmonary artery systolic pressure (PASP) was measured by UCG.Two-sample t test and Pearson correlation analysis were used to analyze the data.Results Both SUV-R and SUV-R/L had negative correlation with LVEF (r=-0.48,-0.33; both P＜0.01) and also with RVEF (r=-0.45,-0.44; both P＜0.01).SUV-R/L positively correlated with PASP (r =0.58,P＜0.01).SUV-R/L of patients with and without LGE were statistically different (0.45±0.18 vs 0.36±0.12; t=2.50,P＜0.05).SUV-R and SUV-L of patients with LGE were 2.0±0.9 and 4.7±1.6,and those of patients without LGE were 1.7±0.9 and 5.0±2.8.Both differences of SUV-R and SUV-L between the two groups were not statistically significant (t=0.54 and 0.63,both P＞0.05).Conclusions Myocardial glucose metabolism in right heart is closely correlated with left and right ventricular function.The assessment of 18F-FDG uptake in right heart by PET imaging is potentially useful for evaluation of the severity and prognosis in IDCM patients.

G protein-coupled inward rectifier K(+) channel 4(GIRK4) is a G protein-coupled inward rectifier potassium channel family member. Encoded by the KCNJ5, it is widely distributed in the mammalian heart, brain, and other tissues and organs. Recent studies have demonstrated that the abnormal expression of GIRK4 gene is associated with atrial fibrillation, and meanwhile may be closely related to obesity, metabolic syndrome, and many other clinical conditions. Further research on the role the GIRK4 gene in the pathophysiology of these clinical conditions will definitely facilitate their clinical diagnosis and treatment.
