Fouty-four patients with craniopharyngioma were admitted trom Junuary 1982 to February 1993 for post-operative radiotherapy. The 5-year survival was 78.9%. Among these 44 patients, 15 were adults and 29 were children. The children gave a higher 5-year survival rate but poorer quality of life as compared with the adults though without statistical significance in the survivals. Among the children, a dose of 56.1～60.0Gy gave better survival as compared with the 45～56Gy group without significance though causing obviously sequelae, eg: amenorrhea and hampered sex development (P

5 ml groups were 95.5% and 81.1% respectively. This difference was statistically significant (P5 ml groups were 4.5 % and 32.1%, respectively (P50 Gy was increased statistically, but the occurrence of complications was also increased. Conclusions Stereotactic radiosurgery improves the outcome of the elderly patients with brain metastases. Radiation dosage and tumor volume are significantly related with the therapeutic efficacy and the occurrence of complications.

Objective To evaluate the prognosis and side-effects of three-dimensional conformal radiotherapy (3 DCRT) and intensity modulated radiotherapy (IMRT) for prostate carcinoma. Methods From 2001 to 2009, 62 patients with prostate carcinoma treated with radiotherapy were included in the retrospective analysis. Among them, 60 patients received IMRT while the other two received 3DCRT. There were 56 patients receiving androgen deprivation therapy before radiotherapy. The median dose was 78 Gy to 95% planning target volume (PTV) of the prostate and seminal vesicles, and the median dose to 95% PTV of the pelvic lymph nodes was 48 Gy. Results The median follow-up was 15.4 months. The 3-and 5-year overall survival (OS) rates were 92% and 83%, with the corresponding biochemical disease-free survival rates of 87% and 69%, and the distant metastasis-free survival (DMFS) rate of 77% and 55%, respectively. Patients with a PSA nadir ≤ 2 ng/ml had a 3-year OS of 94% and DMFS of 88%, compared with 56% and 11% (χ~2 = 16. 39, P < 0.01 for OS ; χ~2 = 28. 87, P < 0. 01 for DMFS) for those with a PSA nadir > 2 ng/ml. The incidence of grade 1 and 2 urinary toxicity was 32% and 0% for acute damage, 10% and 0% for late damage, respectively. The incidence of grade 1 and 2 intestinal toxicity was 19% and 3%. for acute damage, 5% and 3% for late damage, respectively. Conclusions Radiation therapy for patients with prostate carcinoma shows satisfactory outcomes with a good toleration. Monitor of PSA after radiotherapy has benefit for prognosis evaluation.

Objective To analyze the prognostic factors of patients with leukemia treated with single fraction total body irradiation (SFTBI) followed by hernatopoietic stem cell transplantation (HSCT).Methods From January 2001 to September 2008, 102 patients received HSCT. The differences of the survival rate, relapse rate and incidence of interstitial pneumonia (IP) between groups regarding different genders, ages, pathological types, transplantation methods and TBI parameters were compared and the factors related with the survival rate, relapse rate and incidence of IP were analyzed. Results The followup time ranged from 15 to 1482 days (median, 406 days). The follow-up rate was 95.1%. 86 and 55patients were followed up more than one year and three years. The 1-and 3-year survival rates were 59.0%and 44.0%. In univariate analysis, the 3-year survival rate was signifcantly different between the groups with and without relapse before transplantation (20% vs. 55%, χ2 = 6.33, P = 0. 012), allogeneictranplantation versus autologous tranplantation (39% vs. 68%, χ2 = 8.06, P = 0.005), grade 3 or more acute graft versus host disease (aGVHD) and grade 0 -2 aGVHD (0% vs. 54%, χ2 = 7.52, P = 0.006),with and without relapse after transplantation (19% vs. 58%, χ2 = 10.13, P =0.001), with and without IP (23% vs. 58%, χ2 =8.35, P=0.004). Multivariate analysis showed that grade 3 or more aGVHD was the only statistically significant prognostic factors (χ2 = 12. 74 ,P =0. 000). The l-and 3-year relapse rateswere 30. 0% and 50. 0%. The incidence of relapse was obviously higher in the group with relapse before transplantation than that without (47% vs. 16%, χ2 =7. 32, P=0. 007). Multivariate analysis showed thatrelapse before transplantation was a significant factor predicting relapse after transplantation (χ2 = 9. 39,P =0. 020). The cumulative incidence of IP was 35.0%. The incidence of IP was different between groups with dose homogeneity > 3% and ≤ 3% (27% vs. 4%, χ2 = 5. 21, P = 0. 023), with and without acute parotitis (34% vs. 3%, χ2 = 14. 15, P= 0.000), allogeneic transplantation group and autologous transplantation group (31% vs. 8%, χ2= 7.70, P= 0.006). Multivariate analysis showed that transplantation methods, acute parotitis and dose homogeneity were statistically significant factors in predictingIP (χ2 = 10. 08 , 10. 08 and 7.69 , P = 0. 002 , 0. 002 and 0. 010 , respectively) . Conclusions Patients who develop grade 3 or higher aGVHD have poor prognosis. Dose homogeneity influences the incidence of IP. Patients undergoing allogeneic transplantation are apt to have IP. Acute parotitis is related with IP and might be a predictor.

Objective: To investigate the immunological mechanism of influenza A virus for murine S180 ascites sarcoma. Methods: After inoculation with S180 sarcoma cells, mice were i. p. injected with influenza A virus or vehicle 15 days. The average living time and survival rate of the mice were examined. The levels of IL-2, IL-6 and TNF-? were detected. The sarcoma cell's apoptosis was detected by DNA ladder, flow cytometry (FMC) , fluorescent microscope and e-lectron microscope (EM). Results: The average living time and survival rate of the mice injected with Influenza A virus were significantly longer or higher than that of the controls. The levels of IL-2, IL-6 and TNF-? also had the same differences. The apoptosis cells were detected by EM and fluorescent microscope. Sub-diploid peaks were observed by FCM a-nalysis and DNA ladder was seen after electrophoresis in the ascites cells. Conclusion: Our results demonstrated that the feasibility and potential of delivery of influenza A virus as a general means for the treatment of S180 ascites sarcoma.

OBJECTIVE: To investigate the association between microRNA (miR)-149 polymorphism and susceptibility to rheumatoid arthritis (RA ), as well as the clinical characteristics in patients with RA . METHODS: A total of 200 RA patients and 120 healthy controls were recruited from Department of Rheumatology and Immunology of Nanjing First Hospital. After obtaining the informed consent, we collected 2 mL of anti-coagulated venous blood samples from all studied subjects to isolate the whole blood genomic DNA, and the clinical data were collected as well. Single nucleotide polymorphisms of miR-149 rs22928323 were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Correlation between single nucleotide polymorphisms and clinical features were compared. RESULTS: The frequencies of TT, TC and CC for rs22928323 of miR-149 were 25.3%, 51.1% and 23.6% or 18.3%, 20.0% and 61.7% in the patients or the healthy controls, respectively. The onset risk of allele C in RA patients was increased compared with allele T [OR=1.38, 95% CI (1.01-1.75), P=0.023]. There were no significant difference in rheumatoid factor, blood urine nitrogen, antikeratin antibody, and other clinical characteristics among the 3 genotypes in RA patients (P>0.05). CONCLUSION SNP rs22928323 in miR-149 is correlated with RA in the east of Chinese Han population, whereas there is no correlation between miR-149 polymorphism and clinical characteristics in patients with RA.

Objective To study the feature of regional cerebral metabolism rate of glucose (rCMRglc) in patients with Alzheimer’s disease (AD) and the value of positron emission tomography (PET) scanning in diagnosis of AD. Methods 13 AD patients and 13 health controls ,Who matched in age,sex and education years,were scanned with PET. Results (1) Watching by naked eyes,there was mild decreasing of rCMRglc at parietal lobe in healthy elders. While in AD patients,there was widely decreasing of cerebral metabolism rate of glucose. The most significant region was parietal lobe, the next was temporal lobe,and the last was frontal lobe. (2) Detecting with PET and dealing with statistical parametric mapping (SPM) of 99 software,there was more significant decreasing of rCMRglc in regions 7,23,30,31 of cingulate gyrus,region 39 and 40 of pario-occipital lobe,region 20 of temporal lobe and region 6,8,9 of frontal lobe in AD group( P

OBJECTIVETo investigate the features of regional cerebral metabolic rate of glucose (rCMRglc) in patients with mild cognitive impairment (MCI) by positron emission-tomography and its relationship with neuropsychological test.

METHODSPositron emission tomography, mini-mental state examination and Wechsler memory scale were applied in 10 patients with MCI and 10 healthy volunteers as the control group.

RESULTSScores of mini-mental state examination and Wechsler memory scale in MCI patients were lower than those in the control group (P < 0.01). rCMRglc of the left orbital gyrus, right middle temporal gyrus and right putamen was lower in the MCI group than in the control group (P < 0.05). Correlation analysis in the MCI group indicated that rCMRglc of many brain regions such as the orbital gyrus, putamen, left hippocampus and parahippocampal gyrus, cingulate gyrus, left amygdaloid body, precentral gyrus, postcentral gyrus, and medial occipitotemporal gyrus in MCI patients, were correlated negatively with age; while the rCMRglc of many parts of the brain such as the left putamen, temporal lobe, anterior cingulate gyrus, left insular lobe, amygdaloid body, precentral gyrus, postcentral gyrus and medial occipitotemporal gyrus were correlated positively with mini-mental state examination; and rCMRglc of the left putamen, temporal lobe, left insular lobe, precentral gyrus and postcentral gyrus were correlated positively with Wechsler memory scale. The right putamen, the right inferior temporal gyrus, precentral gyrus, and left postcentral gyrus were correlated positively with the length of education. However, only rCMRglc of the left amygdaloid body were correlated positively with gender.

CONCLUSIONThe rCMRglc was lower in the orbital gyrus and putamen of MCI patients. Their rCMRglc were correlated with their cognitive impairment severity, age, length of education and sex.

OBJECTIVETo study the apoptotic effects of influenza A virus on the Raji cell line.

METHODSCultured Raji cells were infected with influenza A virus at a multiplicity of infection (m.o.i) of 20 and the effects of apoptosis were detected at different time points post infection using the following methods: electron microscope, DNA agarose gel electrophoresis, PI stained flow cytometry (FCM) and Annexin-V FITC/PI stained FCM.

RESULTSRaji cells infected with influenza A virus showed changes of morphology apoptosis, DNA agarose electrophoresis also demonstrated a ladder-like pattern of DNA fragments in a time-dependent manner. PI stained FCM showed "apoptosis peak" and FITC/PI stained FCM showed apoptotic cells. Quantitative analysis indicated that the percentage of apoptotic Raji cells increased after infection, and cycloheximide (CHX), an eukaryotic transcription inhibitor, could effectively inhibit the apoptotic effects of influenza A virus in vitro.

CONCLUSIONSInfluenza A virus can induce apoptosis in Raji cell line suggesting that it may lead to a potential method for tumor therapy.
