Objective To investigate the influence of donepezil hydrochloride and hyperbaric oxygen on cognitive function in patients with vascular dementia.Methods 61 cases of patients with vascular dementia were chosen to research,and were divided into research group(31 cases)and control group(30 cases),the control group was treated with piracetam,the research group was treated with donepezil hydrochloride and hyperbaric oxygen,after 12 weeks of treatment congnitive function,daily life quality and adverse reaction between two group were compared. Results The ADL score and MMSE score between the two group had no significant difference before treatment(all P <0.05).The MMSE score of the research group were higher than the control group[(18.71 ±3.29)points vs (15.83 ±3.45)points]after treatment,the difference was statistically significant (t =3.337,P <0.05).The ADL score of the research group were lower than control group[(37.12 ±7.13)points vs (42.53 ±6.74)points],the difference was statistically significant (t =3.026,P <0.05).4 cases of mild to moderate earache and 1 case of mild diarrhea occurred in the research group,and 1 case of upper abdominal pain occurred in the control group,there was no significant difference in the incidence of adverse reactions between the two groups (χ2 =0.803,P >0.05 ). Conclusion Donepezil hydrochloride combined with hyperbaric oxygen could effectively improve the cognitive function of patients with vascular dementia,and with good safety.

By UV induced mutagenesis of protoplasts of Saccharomyces cerevisiae strain f4, f5 and f6, and screening on plates containing different concertration of ethanol at different temperature, we obtained improved strains, such as f4.2, f5.1, f6.2, f4.5. By using a DES to deal with all the improved strains, We obtained two mutants, f5.1.1 and f4.2.1,which have improved ethanol torlerance. We made use of genome shuffling to generate improved strains in this work. We shuffled twice these improved strains by protoplast fusion and finally obtained strains with higher temperature and ethanol tolerance. we also identified shuffled strains that produced more ethanol by shake-flask experments. At the 35℃, the ethanol yield of R24 strain got to 12.93% (W/V), and were almost 5% higher than that of stain f4.

Objective To study the inhibitory effects of Probucol on the expressions of serum promatrix metalloproteinase-2(pro-MMP-2) and matrix metalloproteinase-2(MMP-2) in patients with coronary heart disease(CHD).Methods The levels of serum Pro-MMP-2 and MMP-2 were detected by zymograph and total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C)were measured by enzyme method in 30 CHD patients before and after treatment with Probucol.Results After treatment of Probucol,the expression levels of pro-MMP-2,MMP-2,TC and LDL-C in serum were decreased than those before treatment,respectively;there were obvious differences of various indexes mentioned above between before and after treatment(P0.05).Conclusion Probucol can inhibit the expressions of pro-MMP-2 and MMP-2 in serum as same as TC and LDL-C.Probucol,as one of TIMPs,may be applied to stabilize plaque..

Objective:To observe the biological behaviors of colorectal cancer LS174 cells before and after pcDNA3.0-hugl-1 transfection,so as to investigate the association of hugl-1 with colorectal cancer.Methods:The eukaryotic expression vector pcDNA3.0-hugl-1 was constructed and transfected into LS174 cells.RT-PCR and Western blotting methods were used to analyze the expression of hugl-1 mRNA and protein in LS174 cells before and after transfection.Soft agar colony formation assay,wound-healing experiment,adhesion assay and Matrigel invasion assays were used to study the effects of hugl-1 expression on the proliferation,adhesion,movement and invasion in LS174 cells.Results:The recombinant plasmid pcDNA3.0-hugl-1 was successfully constructed.RT-PCR and Western blotting showed that the hugl-1 expression was higher in cells transfected with pcDNA3.0-hugl-1 than in those un-transfected or empty vector-transfected cells (P

0.05). But according to the data, IL-8 in Qingqinye low dosage group was lower than model group, positive medicine group, Qingqinye high dosage group and Qingqinye middle dosage group. TNF-? in Qingqinye group was lower than model group and positive medicine group, especially in Qingqinye middle dosage group. Pathological section with articular cavity and surrounding tissues were better in positive medicine group and Qingqinye group. Conclusion Qingqinye has a certain effect for repairing joint immune pathological injury in hyperuricemia model rats.

[Objective] To develop a new type nerve tissue engineering scaffolds to repair the defect of peripheral nerve and observe the growth of bone marrow stromal cells cultured in vitro on the scaffolds.[Method]The biomaterial was made of I-collagen and gelatin by freeze-drying method,the alignment regularities of microscopic channels and there course directions were observed under the scanning electronic microscope.The size of the micropores and the factor of porosity were also measured.The bone marrow stromal cells were seeded on the collagen scaffolds and cultured for 5 days,then the growth of bone marrow stromal cells cultured in the scaffolds was observed.[Result]All the scaffolds were circular cylinder,the microscopic channels were arranged in parallel manners,and the pore sizes of the channels were uniform.The bone marrow stromal cells were seeded in the scaffolds successfully.[Conclusion]The developed nerve tissue engineering scaffolds have good structure and biocompatibility,which can be used in the repair of the nerve injuries.

[Objective]To investigate the feasibility and efficacy of percutaneous kyphoplasty in treating severe vertebral body compression fractures in patients with osteoporosis.[Method]Data from 15 patient who suffered from severe vertebral compression fractures was retrospectively reviewed.Seventeen percutaneous kyphoplasty were performed under C arm X-ray machine guidance.The clinical effects were evaluated by observing the charges of visual analog scale,locomotor activity scale,height of vertebral bodies and the Cobb's angle.[Result]All patients were successfully treated.Visual analog scale decreased from 7.9?1.3 preoperatively to 2.5?0.8 postoperatively(P

Objective To observe the effect of Sijunzi Decoction (SD) on the mitochondrial DNA deletion of the aging model mice, and to explore its anti-aging biomolecular mechanism. Methods Kunming mice were divided into 6 groups according to the body weight: normal control group, .model control group, high-, middle-and low-dose SD groups (at the dose of 20, 10, 5 g·kg-1 respectively), and vitamin E group (250 mg·kg-1), 20 mice in each group.The mice models of aging were induced by D-galactose. Water maze test was used to evaluate the learning and memory ability of the aging model mice. The effect of SD on the mitochondrial DNA deletion of the aging model mice was ob-served. Results In the hippocampal mtDNA of model control group and low-dose SD group, there were about 3.87 kb fragment missing. But there was no missing pieces in high-and middle-dose SD groups. Conclusion The anti-aging biomolecular mechanism of SD is probably related to the preventive effect on the mutation and deletion of the mitochondrial DNA in the aging model mice.
