Objective To investigate the spontaneons recovery of calculation and number processing in patients with stroke.Methods Assessment of calculation and number processing were performed in 30 stroke patients with stable conditions (21 cerebral infarction and 9 cerebral hemorrhage) within 3 weeks after stroke,and they were followed up for one year.Calculation and number processing was assessed using the Revised EC301 Calculation and Number Processing Battery in Chinese version at 3,6,and 12 months after stroke onset.Results The scores in the areas of numerical sequences,numerical understanding,numerical transcoding,numerical calculation,numerical knowledge and the total scores increased significantly with the passage of time (all P ＜0.001).There were significant differences between each area and total scores at 3,6,and 12 months after stroke and those at 3 weeks (all P ＜0.01),however,there were no significant differences among the three time points.The total scores and the scores in each area increased significantly with the passage of time in the cerebral infarction group and the hemorrhage group (all P ＜0.001),however,there were no significant differences in each area at the same time point between the two groups.There was significant difference in the recovery of the total scores between the cerebral hemorrhage group and the cerebral infarction group (P =0.008).Pearson correlation analysis showed that the recovery of the calculation and number processing in all patients (R =0.452,P =0.012) as well as in the cerebral infarction group (R =0.683,P=0.001) and the cerebral hemorrhage group (R =0.250,P =0.049) within one year showed a significant positive correlation with the total score of the first assessment.Conclusions The impaired calculation and number processing may partly spontaneously recover after stoke,and it shows significant improvement within 3 months after onset.The recovery in patients with cerebral hemorrhage may be better than that in those with cerebral infarction.The more serious the impairment in initial calculation and number processing,the worse the spontaneous recovery will be.

Objective To explore the key points of graded nursing care to rectal cancer patients with radioactive proctitis induced by preoperative neoadjuvant chemoradiotherapy.Methods The clinical data of 162 rectal cancer patients undergoing neoadjuvant chemoradiotherapy were analyzed retrospectively. The experience of grading nursing care for patients with radioactive proctitis induced by neoadjuvant chemoradiotherapy was summarized.Results Of 162 patients,radioactive proctitis occurred in 110 patients(67.9%).Among the 110 patients with proctitis,62(38.3%)were grade I radioactive proctitis,29(17.9%)gradeⅡand 19(11.7%)gradeⅢ.The graded nursing was done to the patients with radioactive proctitis and achieved good effect.Conclusions Radioactive proctitis has a high incidence in rectal cancer patients with preoperative neoadjuvant chemoradiotherapy and graded nursing care can reduce the distress of patients with radioactive proctitis effectively and promote wound healing,thus to improve their quality of life.

Objective To investigate the adverse reactions by stereotactic body radiation therapy(SBRT)for advanced hepatocellular carcinoma and summarize nursing experience.Methods Forty-one patients with advanced hepatocellular carcinoma from the radiation department of Sun Yat-sen University Cancer Center from July 2010 to May 2012 were enrolled in this retrospective study.The adverse reactions were closely observed and the patients were given pertinent nursing.Results The effectiveness rate was 56.2%.During the therapy,36 patients developed nausea/vomiting of grade 1-2,taking up 87.8%,18 had grade 1-3 elevation of liver enzymes,taking up 43.9%,16 had grade 1-2 decrease of white blood cells,taking up 39.0%,8 had grade 1 anemia,taking up 19.5%and 21 had grade 1-2 decrease of blood platelet,taking up 51.2%.The adverse reactions were contained satisfactorily through careful observations and pertinent nursing.Conclusions The toxic reactions by SBRT are nausea,vomiting,enzymes elevation and decrease of whole blood cell.Therefore,nurses need to observe these toxic reactions carefully and give pertinent care to the patients so as to prevent the complications,especially radiation-induced liver injury.

Objective To investigate errors and the mechanism of acalculia in patients with left or right hemisphere cerebral infarction.Methods Fifty-six patients with single hemisphere cerebral infarction and 56 normal adults who were matched in age,sex and years of education were tested with EC301-CR.The patients were divided into a left hemisphere cerebral infarction group(n =34)and a right hemisphere cerebral infarction group(n =22).Results The scores on 30 out of 32 EC301-CR items were significantly lower among the patients than in the normal control group.Scores on 14 EC301-CR items were significantly lower in the left hemisphere group than in the right hemisphere group.In the left hemisphere group the item scores of aphasia patients were significantly lower than those of no-aphasia patients except on digit identity.Conclusion Mathematical processing and calculation were impaired in patients with single hemisphere cerebral infarction.Calculation was significantly worse among left hemisphere patients compared with right hemisphere cerebral infarction.There was a highly significant correlation between acalculia and aphasia.

Objective To investigate the risk factors,severity and infarct site features and clinical characteristics of the elderly patients over 80 years with cute cerebral infarction.Methods One hundred and sixty-two patients with acute cerebral infarction in Red Cross Hospital of Guangzhou,The Forth Affiliated Hospital of Medical College of Jinan University from January 2012 to May 2015 were enrolled and randomly divided into the elderly patients (≥ 80 years old) and the middle aged patients (＜ 60 years old).The risk factors,national institutes of health stroke scale (NIHSS) scores and Oxfordshire community stroke project (OCSP) criteria were compared between the two groups.Results Coronary artery disease,atrial fibrillation and NIHSS in the elderly patients (25％ (22/88),13.6％ (12/88),7.74 ± 4.986) were significantly higher than those of the middle aged group (12.2％ (9/47),4.1％ (3/74),5.04± 4.305),and the differences were significant (x2 =4.281,4.393,t =-3.649;P＜ 0.05 or P＜ 0.001).The logistic regression analysis finally showed that smoking,hyperlipemia,NIHSS scores and gender(male) were the independent risk factors(OR=3.851,3.609,1.100 and 2.670;P＜0.05).There were more LACI patients in the elderly group than he middle aged group ((40.9％,36/88) vs.(60.8％,45/74),x2 =6.369,P ＜ 0.05).Conclusion Compare to the middle aged patients,occurrence of the elderly patients with acute cerebral infarction is more severe,and the clinical features and risk factors have its particularity.Secondary prevention strategy should be emphasized on the control of different risk factors based on the patients' age.

Objective To explore the effect of PGE1 on the cognitive impairment and the expression of VEGF and BDNF in the hippocampus after bilateral common carotid artery occlusion in adult rats. Methods Forty-eight rats were randomly divided into PGE1 group (10μg·kg-1·d-1, iv), PGE1+VEGFR antagonist group (PGE1, 10μg·kg-1·d-1, iv;SU5416, 25 mg·kg-1·d-1, ip), saline group and sham group (n=12 each). Morris Water Maze test (MWM) was used to examine cognitive function in rats. Drugs and saline were given to VD rats at 24 d for 7 consecutive days following opera?tion. Half of the rats in each group were sacrificed for Western Blot at 6 days after MWM test. Western Blot was conduct?ed to examine the relative expression levels of VEGF and BDNF in the hippocampus. Results Compared to saline and PGE1+VEGFR antagonist groups, the escape latency in PGE1 group was shorter (P<0.05), and the times that rats swam across the platform location and time percentage in previous platform quadrant in PGE1 group was longer (5.77±0.83 vs.2.88 ± 0.47 vs. 2.63 ± 0.44, P<0.01;32.28%± 4.56%vs. 20.42%± 5.50%, 23.08%± 5.06%, P<0.05). Compared with saline group and sham group, PGE1 group had higher levels of VEGF (0.057±0.005 vs. 0.038±0.002 vs. 0.027±0.002, P<0.05) and BDNF (0.481±0.049 vs. 0.339±0.021 vs. 0.224±0.04, P<0.05). but the increase in VEGF expression in PGE1 group was no significant (0.057±0.005 vs. 0.053±0.003, P>0.05) compared with PGE1+VEGFR antagonist group, while the aug?ment of BDNF in PGE1 group was remarkable (0.481±0.049 vs. 0.373±0.034, P<0.05). Conclusions PGE1 can upregu?late VEGF and BDNF expression and modify cognitive impairment in VD rats, while the effects of PGE1 on cognitive function and BDNF expression can be partially blocked by VEGFR antagonist SU5416.

Objective To investigate the clinical value of large platelets (P-LCR) and mean platelet volume (MPV) in acute cerebral infarction patients with type 2 diabetes. Methods 627 patients with acute cerebral infarction from January 2012 to May 2015 were enrolled and divided into type 2 diabetes and non-type 2 diabetes groups. The hemocytometer was used to detect the changes of P-LCR and MPV. Results The levels of P-LCR and MPV in the type 2 diabetes group were significantly higher than those of non-type 2 group (P <0.05). Logistic regression analysis showed that there was a statistically significant association between P-LCR, hypertension and hyperlipemia and the cute cerebral infarction patients with type 2 diabetes. Conclusion The levels of P-LCR and MPV could be used as important indexes for prognosis and early diagnosis of acute cerebral infarction patients with type 2 diabetes.
