Objective To explore the effect of donepezil combined with memantine in ameliorating the cogni-tive function and psychological behavior of patients with Alzheimers'disease(AD).Methods 214 AD patients were randomly divided into the control groupand observation group.The control group were treated with memantine,and the observation group were treated donepezil combined with memantine.Before and after treatment,MMSE and WHO -UCLA AVLT,BEHAVE -AD were utilized to assess the cognitive function,psychological behavior,respectively.The adverse effects were observed using TESS and laboratory examination.Results The scores of MMSE and its subitem, WHO -UCLA AVLT(Immediate memory,short -term memory and long -term memory)after treatment significantly increased as compared with those before treatment in the control group and the observation group(P <0.01 or P <0.05),while the cases of psychological behavior,the score of BEHAVE -AD and its subitem decreased(P <0.01 or P <0.05).The observation group showed statistically significant difference in the increasion of the scores of MMSE and its subitem,WHO -UCLA AVLT,and the decreasion of the cases of psychological behavior,the score of BE-HAVE -AD and its subitem comparison with the control group(t =-1.742,-1.431,-1.626,-2.173,-1.448,-1.026,-1.016,-1.279,-1.971,χ2 =12.295,7.609,8.917,t =0.778,1.139,2.004,1.153,0.822,1.944, P <0.01 or P <0.05).The total effective rate of the observation group was 90.65%,and 71.96% of the control group,there was a significant difference between the two groups(χ2 =12.299,P <0.01).There was no obvious side effects during the treatment in both groups.Conclusion Donepezil combined with memantine can significantly improve the cognitive function and psychological behavior of AD patients,and there are fewer adverse events.

Objective To describe a new classification of pelvic obliquity secondary to poliomyelitis,and investigate the operative indications and effective surgical modes. Methods Fifty-six adult pelvic obliquity secondary to polio were reviewed. The pelvic obliquity was divided into two types and three kinds according to the causes of deformity, X－ ray films of pelvic and gait. Six surgical methods were chosen respectively to correct the deformities. Results All the patients were followed-up for 10 to 80 months(mean 28 months). Complete correction of pelvic obliquity was obtained in 11 patients and major correction in 45 patients. The average corrective rate was 78.3％ . Conclusion Not all the patients with pelvic obliquity after polio need surgical treatment. This new classification has great help to surgical planning and to improve the operative effects.

Objective To evaluate the clinical application of transendoscopic Doppler ultrasonogra-phy in various gastrointestinal diseases. Methods Transendoscopic Doppler ultrasonography was performed in 59 patients with various gastrointestinal diseases. Results The Doppler signals were detected beneath the peptic ulcer base in 29 of 39 patients (74. 4% ) . For acute ulcer bleeding and non - bleeding, the Doppler - positive rates were 87. 5% and 65. 2% , respectively, and the measured depth of vessels were 0. 49 mm and 0. 65mm (P

Objective To explore the correlation of posttraumatic growth with social support in patients with gastrointestinal neoplasms at the end of life.Methods Cluster random sampling was used to select 280 patients with gastrointestinal neoplasms who were predicted to survive no longer than 6 months in 10 first-class hospitals in Beijing and Tangshan,and they were investigated by Posttraumatic Growth Inventor (PTGI) and Social Support Rate Scale (SSRS).Results The total score of PTGI (61.13 ± 16.78)and the scores of appreciation of life (23.71±7.34),personal strength(10.67±3.55),new possibility(10.07±2.11),relating to others(12.54±5.14),spititual change(10.89±4.35)were higher than median value.The total score of SSRS(41.21±8.48) and objective support(10.27±2.75) were higer than the normal level((39.05±6.35),(8.42±2.27)) (P＜0.05).The appreciation of life was positively correlated with subjective support and the total score of SSRS (r=0.25,r=0.26,P＜0.05),personal strength was positively correlated with objective support,subjective support and the total score of SSRS(r=0.24,r=0.29,r=0.23,P＜0.05),new possibility was positively correlated with subjective support(r=0.21,P＜0.05),relating to others was positively correlated with objective support and the total score of SSRS (r=0.26,r=0.26,P＜0.05),spititual change was positively correlated with objective support and subjective support (r=0.28,r=0.31,P＜0.05).The total score of PTGI was positively correlated with subjective support and the total score of SSRS (r=0.29,r=0.29,P＜0.05).Conclusion Patients with gastrointestinal neoplasms at the end of life experience a certain extent of posttraumatic growth and high level of social support.Posttraumatic growth is positively correlated with social support.

Objective To determine the characteristics of early cognitive dysfunction and N300 event-related potentials(ERPs)in patients with acute cerebral infarction(ACI).Methods Thirty patients with ACI and thirty normal healthy elderly people were studied.The two groups were examined with a picture recognition test and EEG waveforms were recorded.The ERPs were analysed statistically.The mini-mental state examination(MMSE) was used to evaluate cognitive function,and the results were correlated with the ERPs. Results The average MMSE scores of the ACI and control groups were significantly different.Reaction times(RTs)in the picture recognition test were(798.63±49.32)ms in the ACI group and(765.21±35.67)ms in the control group,a difference significant at the 5% confidence level.The average accuracy rates,(59.75±8.45)%and(65.26±9.28)%,were also significantly different.Average N300 ERPs the in the ACI group were significantly lower than those in the control group,and the average latencies were significantly longer.Both latency and amplitude in the ACI group showed a linear correlation with MMSE scores. Conclusion The ERPs of ACI patients have some clinical significance,and can be used as a scale-based assessment of cognitive function.

Objective: To study the value of speckle tracking echocardiography (STE) for assessing left ventricular remodeling (LVR) in patients of acute ST-elevation myocardial infarction (STEMI) with late percutaneous coronary intervention (PCI). Methods: A total of 127 STEMI patients with elective PCI were enrolled. Echocardiography was conducted within 48 hours of admission and the patients were followed-up for 6-9 (median 7.8) months after discharge. LVR was deifned by left ventricular end-systolic volume (LVESV) elevation >15% than the ifrst echocardiography. The patients were divided into 2 groups: LVR group,n=41 and Non-LVR group,n=84. Results: There were significant differences between 2 groups in left ventricular global longitudinal strain (GLS), longitudinal Ts-SD, radial strain (RS) and longitudinal postsystolic index. Further Logistic regression analysis indicated that GLS (OR=0.39, 95% CI 0.26-0.57,P<0.01) and RS (OR=1.07, 95% CI 1.02-1.13,P=0.01) were the independent predictors for LVR occurrence; ROC presented that the optimal cut-off value for GLS was -10.85% (sensitivity 89.7%, specificity 91.7%) and for RS was 28.46% (sensitivity 82.1%, speciifcity 66.7%). Conclusion: STE measured GLS and RS were the independent predictors for LVR occurrence in STEMI patients with late PCI.

Objective To evaluate the long-term outcomes of immunosuppressive agents used for myasthenia gravis(MG) patients with disease onset after or at 60. Methods Long-term outcome was evaluated in 99 cases with following-up longer than 1 year. Remission, pharmacological remission, and marked improvement were considered as good results or good long-term outcome. Results All good results were recorded in 79 MG patients (79.8%) receiving immunosuppressive treatments. 48 patients had been treated with glucocorticoids (GC) alone, of them, 35(72.9%) achieved good results. 8 of them having a complete remission for 18 to 67 months (averaging (54.8?19.8) months). 16 patients got pharmacological remission for 7 to 37 months (averaging (15.7?8.0) months). MG patients in different gender had different responses to GC. The good long-term outcome was found in 83.3% (25/30) males and only 55.6% (10/18) in females with GC therapy. There was a rate statistically higher in male than in female patients (P
