Mild cognitive impairment(MCI) is a transition phase between the process of normal aging and the mild dementia.Previous studies have confirmed that besides progress to dementia or death,MCI can also keep stable or convert to normal,and the outcome is different after dividing it into subtypes.This paper mainly discusses the criteria of MCI subtypes,outcome and its possible influential factors.

Objective To assess clinical safety and effect of intracoronary transplantation of autologous bone marrow cells in patients with acute myocardial infarction(AMI).Methods Eighty four AMI patients who had received emergency thromblysis or primary PTCA were enrolled in this study.Elective PCI was undergone in these patients 10-14 days after infarction.During the procedure,50 patients received introcoronary transplantation of autologous bone marrow derived mononuclear cells and the other 34 patients received normal saline as control.All patients achieved TIMI Ⅲ flow after PCI.Dobutamin stress echocardiography,SPECT and F-18-Fluorodeoxyglucose-PET were performed 1 day before and 6 months after the transplantation.All patients finished a 2-year follow up and stress echo examination.Twenty nine patients from the transplantation group and 22 patients from the control group accepted 6-month SPECT reassessment.Results No major adverse events were recorded in all patients who received autologous bone marrow cells transplantation during follow up.Less nitroglycerin usage and increased excercise were observed in the transplantation group.Stress echocardiography showed improvement in LVEF(27.00%?0.89% pre-operation,36.80%?0.58% after 6 months and 40.94%?0.58% after 2 years,P

Objective To summarize the clinical outcomes after the optimization of nutrition support in elderly patients after hepatic carcinoma surgery.Methods The clinical data of 52 elderly patients with hepatic carcinoma in Beijing Hospital were collected and analyzed from 2007 to 2009(research group).Nutritional Risk Screening(NRS)2002 was applied for the nutrition risk screening at admission.NRS 2002 score≥3 was regarded as at nutritional risk.Enteral nutrition(EN)or EN combined with parentoral nutrition(EN+PN)supports were provided during the peri-operative stage.The control group included 30 patients from 2005-2007 under the same conditions with rescareh group but only received PN supports pest-operatively.Nutritional parameters,complications,lengh of hospital stay,and healthcare expenditures were analyzed.Results Body weight and plasma albumin were no significantly different in two groups(P>0.05)by the 7th post-operative day.The incidence of infection-relatod complications and length of hospital stay were significantly lower in research group than in control group (P<0.05).Conclusions Nutrition risk screening should be performed for the elderly patients with hepatic carcinoma after admission.Optimization of peri-operative nutrition support can reduce complications and improve the clinical outcomes.

Objective To evaluate the helical CT diagnostic value of primary retroperitoneal neoplasm(PRN). Methods 32 cases of PRN confirmed by operation and pathology were retrospectively analyzed. Plain and enhanced CT scan were perfomed in 28 cases,and only 4 cases underwent plain CT scans. Results Of 32 cases,15 were benign tumor and 17 cases were malignant tumor.Among them ,16 cases were mesenchymal tissue-origin(11 cases were malignant neoplasm), 10 cases were nervous tissue-origin(3 cases were malignant neoplasm),3 cases were rudimental embryonal tissue-origin(all benign), and the source of unknown-origin were 3cases(all malignant neoplasm).To be correctly localized was 28 cases(87.5%) and correctly qualitative diagnosis of the tumor was 20 cases (62.5%) by CT before operation. Conclusion PRNs have many typies, helical CT provides informations in both position and characteristics before operation.

Objective To explore the value of helical computed tomography (CT) in differential diagnosis of xanthogranulomatous cholecystitis (XGC) and wall-thicked gallbladder cancer (GBC).Methods The CT signs of 18 XGCs and 20 wall-thicked GBCs were retrospectively analyzed.The maximum thickness of gallbladder wall, intramural hypoattenuated nodules, mucosal line of gallbladder inner wall,patterns of enhancement of thickened wall,whether combined with stones,the pericholecystic adjacent liver tissue involvement and biliary tract obstruction were observed.Measurement data were analyzed by independent sample t test and count date were analyzed by Fisher precisely the probability method.Results The mean maximum thickness of the gallbladder wall of XGC and wall-thicked GBC was (22.11±10.19) mm and (20.55±7.94) mm respectively,and there was no statistical significance (t=0.530,P=0.600).Eighteen cases of XGC and five cases of wall- thicked GBC patients were with intramural hypoattenuated nodules (Fisher precisely the probability method,P＜0.01 ),14 cases of XGC and six cases of GBC were with integrated mucosal line (Fisher precisely the probability method,P =0.004 ),three cases of XGC and 12 cases of GBC were with biliary tract obstruction (Fisher precisely the probability method,P=0.009).There was no statistical significance in the CT signs of the range of wall thickness,patterns of enhancement and enhanced degree of thickened wall,adjacent liver tissue involvement, lymphadenopathy, combined with gallbladder or bile duct stone between XGC and wall-thicked GBC patients (Fisher precisely the probability method,all P ＞ 0.05).Conclusions The thickened gallbladder wall with intramural hypoattenuated nodules and integrated gallbladder inner wall mucosal line were characteristic signs for diagnosing XGC.Helical CT scanning can provide evidence for differential diagnosis in XGC and wall- thicked GBC.

ObjectiveTo investigate the prevalence of nutritional risk and malnutrition among hospitalized elderly abdominal surgical patients with malignant tumors.MethodsTotally 269 elderly patents ( ≥ 65 years) with malignant tumor who were hospitalized in our department of abdominal surgery from December 2009 to November 2010 were consecutively enrolled.Nutritional Risk Screening 2002 ( NRS 2002 ) was performed on the next morning after admission.Body mass index (BMI) lower than 18.5 kg/m2 was considered as malnutrition.Results The NRS 2002 was completed in all the 269 enrolled patients.The overall prevalence of malnutrition was 30.1％ (81/269) ; more specifically,37.5％ (21/56) among geriatric patients ( ≥80 years) and 17.6％ (43/245) among the other age groups (P =0.001 ).The overall rate of nutrition risk was 38.3％ (103/269) ; more specifically,57.1％ (32/56) among the geriatric patients and 29.3％ (72/245) among the other age groups (P ＜0.001 ).The rate of nutrition risk in patients with pancreas cancer was 58.3％,which was higher than other elderly patients; on the contrary,and the rate of nutrition risk in the patients with colorectal cancer was relatively lower.ConclusionThe rates of nutrition risk and malnutrition in hospitalized elderly abdominal surgical patients ( ≥ 65years) with malignant tumor are relatively higher than other age groups,especially among the geriatric patients.

ObjectiveTo explore the clinical outcome of the combined nutrition support for colorectal cancer patients.MethodsTwo research arms were obtained using a cohort sampling method.Ann A ( the study group): from 2009 to 2010,30 colorectal cancer patients were enrolled.They received nutritional risk screening (NRS) 2002 after admission.Nutritional risk was defined as NRS 2002 score ≥3 three days before operation.Patients with nutritional risk received enteral nutrition (EN) for bowel preparation without laxative drug and enema.After operation,they received EN combined with parenteral nutrition (PN) supports provided.Arm B (control group): 30 cases with historically confirmed colorectal cancer were enrolled from 2007 to 2008.They received routine bowel preparation (diet control,laxative drug,and enema) and PN supports after operation.Nutritional parameters,the rate of infectious complications,the rate of systemic inflammatory response syndrome,and the duration of hospital stay were analyzed.ResultsThere were no significant difference in body weight and plasma albumin between these two arms ( P ＞ 0.05 ). The incidence of systemic inflammatory response syndrome (13.3 ％ ),infectious complications (10.0％ ),and the duration of hospital stay [ (12.3 ± 6.5 ) d ] in arm A were significantly lowerthan those in arm B [33％,30％,and (15.0 ±7.2) d,respectively] (P =0.038,P =0.042,P =0.045).Conclusion For the colorectal cancer patients,nutritional risk screening on admission,bowel preparation with eneral nutrition before operation,and combined nutritional support after operation can improve the clinical outcome.

Objective To compare the benefits of the combined nutrition support with enteral nutrition (EN)and parenteral nutrition(PN)versus sole PN for elder patients after pancreaticoduodenectomy.Methods The clinical data of 48 consecutive elderly patients who underwent Whipple operations in Beijing Hospital were retrospectively analyzed.Patients were divided into PN+EN group(n=25)and sole PN group(n=23)according to the nutrition support modes.Demographic data as well as data on liver function,endotoxin levels,and post-operative complications were recorded.Mortality,length of hospital stay,and total costs of post-operative management were compared between two groups.Results Endotoxin level increased on the 1stpost-operative day(POD 1) in two groups,but there is not significant difference,and then gradually decreased in beth two groups;however,the decrease rate(compared with the POD 1 level)was significantly higher in PN+EN group than in PN group on POD 7 and 14(P<0.01).The levels of alanine transaminase,aspartate aminotransferase,total bilirubin,and direct bilirubin increased on POD 1 in both groups,but there is not significant difference,and then gradually decreased;however,the decrease rates(compared with the levels on POD 1)were also significantly higher in PN+EN group than in PN group(P<0.05)on POD 14.Infective complication rate in group PN+EN(2/25,8.0%)was significantly lower than that in group PN(6/23,26.0%)(P<0.05).Total complication rate,post-operative hospital stay,and total costs were similar between these both groups.Conclusions PN+EN can effectively reduce endotoxemia and post-operative infective complications and improve liver function without increasing costs.Therefore,it is feasible for elderly patients after pancreaticoduodenectomy.

Objective To investigate the nutritional risk,malnutrition rate,and nutritional support in elderly inpafients with hepatobiliary diseases.Methods Totally 156 eldedy inpatients(≥65 years)with hepatobiliary diseases were consecutively enrolled.Nutritional Risk Screening 2002(NRS 2002)was applied to screen nutritional risks on the next morning after admission and two weeks after admission or on the discharge day.Results Of 156 enrolled patients,151 patients(96.8%)completed the NRS 2002 screening.The nutrition risk and malnutrition rate were 36.9%(57/156)and 26.2%(41/156),respectively.The nutrition risk and malnutrition rate were significantly higher in patients with a hospital stay longer than 2 weeks than those with a hospital stay less than 2 weeks(49.6%and 36.7% vs.37.3%and 21.4%,respectively)(both P<0.05).In addition,100 patients(64.1%)with nutrition risk received nutrition support and 27 patients(17.3%)without nutrition risk received nutrition support.Among patients who had undergone major abdominal surgeries,137 patients(87.9%)with nutrition risk received nutrition support while 57 patients(36.8%)without nutrition risk received nutrition support.Conclusions NRS 2002 is a feasible nutritional risk screening tool for elderly inpatients with hepatobiliary diseases.A hospital stay more than 2 weeks the morbidity of the nutritional risk and malnutrition rate increased.Seems the value of nutritional support has not been well recognized in the department of hepatobiliary surgery,inappropriate application of nutritional support still exists.

Objective To explore the effects of L-carnitine on the plasma lipid profile and liver function in elderly patients receiving total parenteral nutrition after abdominal operations.Methods In this prospective blinded randomized controlled trial,24 eligible elderly patients were given 6-day total parenteral nutrition.They were further equally divided into L-carnitine group(administered with L-carnitine 50 mg/kg)and control group(without L-carnitine).The changes of lipid profile and liver function and the clinical outcomes were recorded and compared.Results The plasma triglyeride levels were lower in L-carnitine group than in control group on the 4th and 7th post-operative day,but there were not significant difference(P>0.05);There was a significant difference between the two groups in the change of the 4th post-operative day and pre-operative day(P<0.05).However,the liver function indicators were not significantly different between these two groups.Conclusion Administration of L-carnitine during total parenteral nutrition can improve the triglyeride metabolism in elderly patients after abdominal operations and may benefit the recovery of liver function.
