Objective To examine the effect of donepezil on cognitive function of Alzheimer's disease from a naturalistic observation in memory clinic.Methods From the subject pool in memory clinic,thirteen patients with mild to moderate Alzheimer's disease(meeting NINCDS-ADRDA criteria of probable AD)were enrolled in the naturalistic observation.Donepezil with dosage of 5 mg daily Was administered.Cognitive Ability Screening Instrument (CASI)Was used to assess the cognitive function,and was administered at baseline,3 and 6 months after treatment with donepezil.Resuits After 6-month treatment with donepezil,the change of score of verbal fluency from baseline Was significant[(4.3±3.1)vs(6.2±2.7),P＜0.05].There was a trend that constructional praxis was also improved after 6-month treatment(P=0.06).The change of scores of other cognitive domains remained the sanle(P＞0.05).Conclusion In the naturalistic observation at memory chnic,donepezil may improve verbal fluency of AD patients,and keep most cognitive function stable.

Objective: Through comparing the hospitalization costs of total knee replacement (TKR) in People’s Hospital of Peking University in 2005 and 2010, to investigate the changing status of hospitalization costs on this operation and the impact of clinical pathway ( CP ) on controlling the hospitalization costs during 5 years , and provide references for controlling medical treatment cost reasonably. Methods: The patients are grouped into undergoing unilateral and bilateral TKR. The total hospitalization cost and cost of each category during 5 years are compared, and SAS 9.2 statistic software is applied to deal the data. Results: Compared with 2005, the total cost for TKR in 2010 decreased. All the charging items decreased, except implant material increased, especially the cost of surgery, hospital room, nursing and pharmacy. Specific to one knee replacement group and both knees replacement, the changing trend of cost is coincident with the total cost. Conclusion: The total cost for TKR in 2010 was lower than that of 2005, which might be the result of adopting CP since 2010. Nevertheless, the implant material cost accounted large proportion of hospitalization cost in 2010, and it has obvious increasing trend compared to 2005. This result is related the increasing application of the new edition of Artificial knee joint prosthesis. Controlling implant material cost is the effective method of decreasing medical costs for TKR.

Objective To evaluate the clinical value of microvascular anastomotic devices in free anterolateral thigh flap in the recon-struction of oral carcinoma defects.Methods From September 2013 to September 2014,52 patients with oral cancer were treated by func-tional neck cleaning,primary tumors resection,and free anterolateral thigh flap in the reconstruction.Of which 27 patients received free of femoral anterolateral flap to repair veins by using microsurgical line end to end anastomosis.And 25 pieces of microvascular anastomotic ad-vices were applied in 25 patients with oral carcinoma defects.The length of anastomosis time,flap survival rate,and complications were recor-ded.Results In 52 patients,microvascular anastomotic devices were applied in 25 veins with shorter anastomosis time,(6.3 ±1.9)min vs. (12.3 ±1.4)min,and the difference was significant(P =0.001).The flap survival rate and vascular anastomosis patency rate was 100%.No intra-and post-operative complications such as blood leak,stapling,excessive tension and tear,thrombosis in flap vein crisis associated with microvascular anastomotic devices were observed.Twenty-seven patients with 40 root vein received manual microsurgical anastomosis,2 of them showed vein crisis.Conclusion The microvascular anastomotic devices used in repairing the soft tissue defects by anterolateral thigh flap with venous anastomosis for patients of oral cancer after surgery has the advantage of higher quality,shorter time and less complications.

Objective To study the effects of metformin on proliferation and apoptosis of oral squamous cells so as to create a new path for the treatment of oral carcinoma.Methods CAL27 cells were treated with different dosage of metformin(5,10,20 mmol/L)for 24,48, and 72 hours.The number of apoptosis was detected by flow cytometry and TUNEL.The autophagic vacuole was detected by immunofluores-cence.The expression of hallmark of apoptosis and autophagy was detected by Western blot.Results Metformin could induce apoptosis in CAL27 cells.The CL-PARP and Bcl-2 expression significantly increased.In line with the apoptosis,metformin can trigger autophagy in CAL27 cells.The expression of LC3,Beclin-1 and GFP-LC3 positive autophagosomes were increased by metformin.Metformin inhibit the expression of STAT3 and mTOR signaling pathways at the same time might be the possible reasons of the autophagy.And inhibited autophagy could en-hance metformin induced Caspase-3 activity in CAL27 cells.Conclusion Inactivation of STAT3 and mTOR pathway contributes to metform-in-induced autophagy.Inhibited autophagy could enhance metformin induced apoptosis in oral squamous cell carcinoma.

Objective To investigate the efficacy of butylphthalide on elderly patients with acute cerebral infarction and its effect on serum uric acid,c-reactive protein,and hemorheology.Methods Elderly patients (86 cases) with acute cerebral infarction in Xi'an No.1 Hospital from January 2015 to December 2015 were randomly divided into two groups.The control group was treated with conventional symptomatic treatment of acute cerebral infarction,observation group added with butylphthalide soft capsules.The NIHSS score and efficacy of the two groups,the serum uric acid,c-reactive protein,and the change of hemorheology before and after treatment were compared.Results The effective rate of observation group was 90.70％,significantly higher than that of control group 72.09％ (P ＜ 0.05);The NIHSS score,serum uric acid and c-reactive protein levels,blood viscosity and platelet aggregation rate of two groups after treatment were significantly lower (P ＜ 0.05),the Barthel index were significantly increased (P ＜ 0.05),and the change of observation group were more significant (P ＜ 0.05).Conclusion Butylphthalide has high curative effect on elderly patients with acute cerebral infarction,can reduce the level of serum uric acid,c-reactive protein and the degree of nerve function defect,improve the hemorheology and life self-care activities ability,which can protect the brain.

Objective To discuss the clinical character and the therapeutic strategy of the super-proximal bicondylartibial plateau fracture.Methods A review of 8 patients with an average age of 40.8 years old (range,28-56 years; 6 males,2 females) surgically treated from June 2007 to October 2012 was conducted.Conventional pre-operative three-dimensional CT scans were used to clarify the types of fractures and the locations of major displaced bone fragments.All patients received open reduction and internal fixation 7-14 days after injury for recovery of soft tissue.Anterolateral incision combined anteromedial incision was made on those with limited posterior column shift.Otherwise anterolateral incision combined posteromedial might be better for those with obvious displacement.Six of the patients were implanted autograft bone or allograft bone.The collateral ligaments could be repaired in one stage,but a routine repair of cruciate ligaments was not concerned,and an immobilization for six weeks with a plaster or a brace should be followed.Results All cases were followed-up for 12 to 26 months (median follow-up period,18.6 months).All the fractures in the series achieved bone union at or before the last follow-up,and the healing time ranged from 18 to 26 weeks (median healing period,21.5 weeks).The X-rays showed the smooth surface and good alignment of knee joint at the last follow-up.The median hospital for special surgery knee score (HSS) was 78.12 (range,56-90),with 3 excellent cases,3 good cases,1 fair cases and 1 poor case; the excellent and good rate was 75％ (6 of 8).The median Lysholm score was 81.37 (range,58-91),with 4 good cases,3 fair cases and 1 poor case; the excellent and good rate was 50％ (4 of 8).Conclusion Super-proximal bicondylartibial plateau fracture is a special fracture type accompanied with posterior dislocation of knee,which is predominantly presented as an anterior plateau fracture.And injuries of blood vessels and nerve are common.Conventional pre-operative three-dimensional CT scans,paying attention to the stability of the knee,restoring the alignment and joint surface and early analgesic exercises with brace might be commended in management of such plateau fracture.
