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 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 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 investigate the physicochemical characteristics of urinary stone induced by ceftriaxone.Methods Two children cefriaxone-associated urinary stone samples were received for component analysis in our hospital in April 2012,of which one was from a boy whose clinical data was not available,and the other was from a boy who suffered acute lower abdominal pain and vomiting after treatment with ceftriaxone for 5 d in early April.Ultrasound demonstrated a stone in his right upper ureter.Computed tomography showed right upper ureteral stone,which was radiolucent on plain abdominal radiograph.After a conservative treatment for 3 d,the stone in right upper ureter was spontaneously passed,which was confirmed by the ultrasound and intravenous pyelography.The two received stone samples were analyzed by infrared spectroscopy,scanning electron microscopy and energy disperse spectroscopy for component analysis.Results The compositions of two stone samples were free ceftriaxone and calcium ions combined with a molar ratio of 1:1.Conclusions The ceftriaxone could induce urinary stone in children.This special stone has radiolueent imaging,and it is composed of calcium ceftriaxone salt.

Objective To evaluate the accuracy and sensitivity of three techniques in the diagnosis of renal diseases following multiple myeloma. Methods 41 serum samples from the kidney-damaged patients with multiple myeloma and 36 from the control group with general renal diseases were detected by quantitative analysis of immunoglobulins, serum protein electrophoresis and serum Immunofixation Electrophoresis. The accuracy and sensitivity of the three techniques were analysed by Two-way ANOVA and Multiple Comparisons of the check-out rate of monoclonal immunoglobulin. Results No monoclonal components were checked out by quantitative analysis of immunoglobulins. The checkout rate of IgG and IgM myelomas were 100% by serum protein electrophoresis, which had application limit on other types of myelomas. Whereas all secretarial myelomas could be diagnosed and typied by Immunofixation Electrophoresis, the sensitivity and accuracy was 100%, there was no false positive in the control group. Comparing with quantitative analysis of immunoglobulins and serum protein electrophoresis, serum Immunofixation electrophoresis had higher sensitivity and accuracy in diagnosis of renal diseases following multiple myeloma ( P
