Objective To probe the feasibility of single dose contrast enhanced magnetic resonance aortography(CEMRA) and evaluate its value in clinical application. Methods Transit time(TT) test and duration of peak enhancement of aorta(DPE) test in 28 healthy adults were performed. With 2 different injection rate of Gd DTPA at 2 ml/s and 3 ml/s, the TT,peak signal intensity of aorta(SPE),DPE and the interval between DPE and the time of injection(?T) were measured and compared. Two groups of healthy volunteers(each 10) underwent three diamentional fast imaging in static procession sequence (3D FISP) CEMRA with standard dosage of Gd DTPA with the injection rate at 2 ml/s and 3 ml/s respectively. The signal/noise ratio(SNR) of the source images and the image quality of CEMRA of both groups were compared. Fifteen patients with aortic disease did the same study as the voluteers with the injection rate only at 3 ml/s. Results With the injection rate of 2 ml/s and 3 ml/s,the TT,SPE,DPE,?T and the SNR of CEMRA in two groups were significantly different( P

Objective To investigate the clinical characteristics of colorectal cancer and its trend in Guangdong province.Methods The data from 6501 patients with pathologically confirmed colorectal cancer of 5 hospitals from 1990 to 2004 was analyzed.Results The mean age of 6501 patients with colo- rectal cancer was 59 years old,with the predominant age ranged from 61 to 70 years old.The proportion of young patients decreased from 7.1% to 3.5%.and the ratio between male and female was 1.47:1, which was gradually increased with increasing of age.The prevelence reached a high peak(60 years old) and dropped after that as a single peak curve.The ratio between rectal cancer and colon cancer was 1.1: 1,and the descending colon cancer accounted for 27.6%.With ageing,the rectal cancers decreased while the right hemi colon cancer increased gradually.Tubular adenocarinoma was predominant with his- tological typing,which accounted for 76.0%.The progressing stage(Dukes B,C,and D)was found in 93.9% of all cases.Conclusions The onset age of patients with colorectal cancer become close to west- ern country.The proportion of young patients are decreasing.The ratio between male and female dis- plays a single peak curve from rising to dropping.A tendency of decreasing percentage in rectal cancer and the gradual increasing in right hemi colon cancer emphasize the importance of colonoscopy in colorec- tal caner screening.

OBJECTIVETo explore the incidence, degree, and pattern of rib cartilage calcification in congenital microtia patients, in order to provide reference for harvesting the rib cartilage, sculpturing cartilage framework.

METHODSFrom Jun. 2013 to Nov. 2014, 383 patients (age range, 6-45 years) underwent CT scans of the chest. 11 patients with bony diseases or traumatic history were excluded. The remaining 372 patients were divided by age into four groups as 6-15, 16-25, 26-35, 36-45 years old. Twenty patients (10 male and 10 female) were selected by the order of patient identification number in each age group, thus selecting a total of 80 patients (40 male and 40 female). Retrospective study of CT scans of the chest in 80 patients and the incidence, degree, and pattern of cartilage calcification of the sixth to eighth ribs were noted. A chi-square test is conducted to test whether there are significant difference between the variables through the SPSS 19.0 software.

RESULTSOverall, 40.4% (194/480) cartilage was calcified; female patients (47.50%, 114/240) showed higher frequency of calcification than male patients (33.33%, 80/240, P = 0. 025). Calcification rates of all age groups are 1.7% (2/120), 46.7% (56/ 120), 49.2% (59/120), 64.2% (77/120). Calcification rate of 6-15 years group is lowest in all groups (P < 0.05) while other three groups have no statistical significance (P > 0.05). Calcification rates of the sixth and sevent rib cartilage were higher than those of the eighth rib cartilage in all age groups except 6-15 years group, who had a similar rate of all three ribs. Calcification rate of all three rib cartilage was significantly increased with age. Calcification rates of the amle's rib cartilage and the female's in all age groups are 3.3% (2/60) and 0.0% (0/60) (6-15 years): 33.3% (20/60) and 60.0% (36/60) (16-25 years): 40.0% (24/60) and 58.3% (35/60) (26-35 years), 56.7% (34/60) and 71.2% (43/60) (36-45 years). In 6-15 years group calcification rates of male and female had a similar rate, while female's rates were higher than male's rates in other three groups. Male and females mainly had the granular type of calcification [70.0% (56/80), 63.2% (72/114)].

CONCLUSIONSFemales who are over 16 years old should pay more attention to the possibility of middle-severe calcification before harvesting rib cartilage. These patients should take CT examination if necessary. In addition, the patients who had previous operation, or traumatic history, rib deformity, or spine deformity should select the CT examination.

Objective To explore the role of long-term enriched environment in promoting the recovery of motor and social function in mice after ischemic brain injury. Methods Sixteen adult male ICR mice underwent permanent middle cerebral artery occlusion (MCAO). The first day after operation, they were divided into enriched environment group (n=8) and standard condition group (n=8). The mice were tested with modified Neurological Severity Score (mNSS), rotarod test and smart cage 7, 14, 21, 28 days after modeling. Results The score of mNSS and the result of rotarod test improved more in the enriched environment group than in the standard condition group 28 days after MCAO (t>2.927, P<0.05). The occupancy time in the middle of smart cage was longer in the enriched environment group than in the stan-dard condition group 7 to 28 days after MCAO (t>2.480, P<0.05) in the general move test. There was a trend of being more interested in strange mice in the enriched environment group than in the standard condition group, but the difference was not statistically significant (P>0.05) in the social behavior test; however, the occupancy time in the middle of smart cage was longer in the enriched environment group than in the standard condition group 14 to 28 days after MCAO (t>3.472, P<0.01), and the velocity of moving was higher 14 days after MCAO (P<0.05). Conclusion Enriched environment could promote the recovery of motor function, somehow of social function, in mice af-ter ischemic brain injury.

Objective To observe the prevalence of cancer-associated anemia and its effect on elderly patients with advanced cancer.Methods Functional Assessment of Cancer Therapy-Anemia Version 4 (FACT-An) was used to investigate the quality of life (QOL) of 86 elderly patients with advanced cancer.The patients were divided into anemia group and non-anemia group.The influence factors for QOL of the elderly patients with advanced cancer were examined,and a multivariate regression was used.Results The prevalence of cancer-associated anemia in elderly patients with advanced cancer was 61.63 ％ (53/86).The scores in physical well-being (16.03±4.14 vs 12.47±4.68,P =0.001),emotional well-being (11.30±3.98 vs 9.45±4.04,P =0.041),functional well-being (13.61±3.74 vs 10.30±4.02,P ＜ 0.001),additional concerns (57.39±7.28 vs 40.06±10.45,P ＜ 0.001) and FACT-An (111.70±13.19 vs 84.34±18.95,P ＜ 0.001) of the non-anemia group were all significantly higher than those of the anemia group.The multivariate regression analysis results indicated that hemoglobin (P ＜ 0.001),comorbidities (P =0.002),performance status (P =0.018),age (P =0.030) were the influence factors for QOL of elderly patients with advanced cancer.Conclusion The morbidity of anemia in elderly patients is increased and it affects the QOL of senior patients with advanced cancer.
