Alzheimer's disease (AD) is a complex and progressive neurodegenerative disorder. The available therapy is mainly Acetyl cholinesterase (AChE) inhibitors and N-methyl-D-aspartate (NMDA) antagonist, which are single-target AD drugs. They are limited symptomatic treatment and their efficacy remains unsatisfactory. Due to the complexity and multifactorial etiology of AD, the multi-target-directed ligand approach is a hopeful way of searching new anti-AD drugs. Here we review the advancement of multitarget AD drugs in recent years: single compound with more than one target, multicomponent drug and drug combination.

BACKGROUND: Several studies have demonstrated that the range,thickness and morphology of oral prosthesis directly influence patient's phonetic function,and titanium base and polymethyl methacrylate(PMMA)resin base yield different influences on phonetic function due to different thicknesses of materials.OBJECTIVE: To analyze the phonetic parameters in one complete denture patient who wear titanium base and PMMA resin base simultaneously and investigate the influences of maxillary complete denture base on phonetic function.METHODS: Through the use of computer-based voice analysis software PRAAT4.4.34,frequency value of the first concentrated frequency area when speaking consonant sounds/x,sh,r,zh,ch,j,q/and voice onset time when speaking consonant sounds/g,k,zh,ch,j,q/were statistically analyzed in the same patient who separately wear titanium complete denture base and PPMA resin complete denture base,and spectrogram of velar stops between complete denture bases was compared.RESULTS AND CONCLUSION: MMPA resin complete denture base was to some extent poor in promoting the recovery of phonetic function owing to great base thickness.Titanium complete denture base with less thickness in the tongue or palate region would help recovery of phonetic function.Extraction and analysis of phonological parameters,such as frequency value of first concentrated frequency area and voice onset time,using CSL computer*based voice analysis system,would provide objective evidence for lamprophony analysis after wearing complete denture.Maxillary denture with thinner base in tongue and palate regions better promotes the recovery of patient's phonetic function.

Objective To study the heart rate variability(HRV) and blood pressure variability(BPV) in patients with different grades of hypertension.Methods 120 cases of patients with hypertension,according to 1999 WHO/ISH hypertension diagnostic criteria are:1 hypertension in 40 cases,2 of hypertension in 40 cases,3 of hypertension in 40 cases and 40 cases of normal control group were detected heart rate variability and blood pressure variability.Results HRV was significantly different between the two groups(P <0.05 or p <0.01).The blood pressure increased and HRV tended to decrease.The BPV was significantly different(P < 0.01) between the two groups;the blood pressure increased and the BPV tended to increase.Conclusion The grade of hypertension is related to HRV and BPV.

The application and studies of reduced diameter implants(RDI)are increasing recently.A case with fracture of three 3.3 mm ITI implants in maxilla was reported in this paper.Combined with the related literature,overload,mechanical complications(such as fatigue, crevice corrosion and hydrogen embrittlement)and the insufficiency of mechanical properties of RDI may lead to the fracture.

Objective To evaluate the efficacy of non-Hodgkin's lymphoma(NHL)treated by high does MTX,autologous peripheral stem cell transplantation and biotherapy for 67 cases.Methods Sixty-seven NHL patients from June,2003 to March,2007 were treated by three times HD-MTX,APBSCT and biotherapy of IL-2.Results There were 36 cases(87.8%)in complete relase(CR)period;5 cases(12.2%)in relapse(RE)period and 1 patient(2.4%)died in CR group;in PR group,there were 15 cases(57.7%)in CR period;11 cases(42.3%)in RE period and 5 patients(19.2%)died.Conclusion These preliminary results suggest that the therapy can be performed safely.It is an efficacious therapeutic measure for the patients with non-Hodgkin's lymphoma.

Objective To evaluate clinical effect of autologous peripheral blood stem cell transplantation(APBSCT)on the treatment of hematologic malignancies.Methods Totally 231 patients(ALL in 45 cases,AML in 34 cases,NHL in 100 cases,HD in 31 cases,MM in 21 cases)with hematologic malignancies received APBSCT from March 2001 to February 2007.Therapeutic effect and complication were oberserved.Results Totally 230 patients obtained hematopoietic reconstitution quickly,one case failed.ALL CR1(first time CR):13 in DFS,4 alive with disease(LWD),11 in death;ALL CR2(second time CR):3 in DFS,4 in LWD,10 in death;AML CR1:12 in DFS,3 in LWD,6 in death;AML CR2:6 in DFS,2 in LWD,6 in death;NHL CR:43 in DFS,7 in LWD,9 in death;NHL CR2:18 in DFS,5 in LWD,7 in death;NHL NR:2 in DFS,4 in LWD,5 in death;HD CR1:10 in DFS;HD PR:12 in DFS,3 in LWD;HD RE:3 in DFS,2 in LWD,1 in death;MM:7 in DFS,6 in LWD,8 in death.Conclusion APBSCT is a safe and effective therapy method for treating hematologic malignancies.

Objective To evaluate the clinical effect of Easy Prosthesis D-10 on open preperitoneal groin tension-free hernioplasty.MethodsThe operative time,operation-correlated complications,hospital stay and recent follow-up findings of 63 patients underwent preperitoneal groin tension-free hernioplasty were analyzed from October 2006 to April 2008.ResultsNo case died in perioperative period.The average operative time was(47.6?10.5)minutes.None of incision infection and scrotal hydrocele occurred.The average hospital stay was(7.7?2.1)days.During follow-up period of 6 to 24 months,no recurrence,chronic pain and foreign body sensation were found.ConclusionThe open preperioneal groin tension-free hernioplasty by Easy Prosthesis D-10 is safe and reliable,especially for the inguinal hernia with large hernia ring or defect of transversalis fascia and recurrent hernia.

Objective To study the expression of hepatocyte growth factor (HGF) in placenta from normal pregnancy and pregnancy induced hypertension (PIH) and the effect of HGF on angiogenesis in placenta. Methods Immunohistochemistry was used to determine the location and intensity of HGF staining in placenta from 20 cases of normal pregnancy and 58 cases of mild,moderate and severe PIH groups. HE staining was used in order to count the number of the vessles. Results HGF mostly were expressed in villous core mesenchymal cells,less in decidual cells . Intensity of HGF immnostaining in villous mesenchymal cells was significantly reduced in the severe PIH group compared with the normal group(H=7.395,P=0.003),while there were no statistical differences between the mild,moderate PIH group and the normal group (H=0.869,P=0.351,H=0.017,P=0.896) .The count of vessels reduced in severe PIH (F=10.676,P=0.008). There was positive correlation between the expression of HGF and the count of vessels in villous(r=0.246,P=0 030). Conclusion These results suggested that HGF is secreted mainly by villous core mesenchymal cells in human placenta and the reduction of HGF in PIH may be responsible for the impaired vascularization in PIH.
