Objective:To study the effects of fluor-hydroxyapatite (FHA) coating titanium alloy on the osseointegration and peri-implantitis of orthodontic micro-implant.Methods:Titanium of FHA alloy (FHA group) and titanium alloy(control group) orthodontic micro-implants were respectively planted into buccal alveolar bone in mandibular premolar area of rabbits.Scanning electron microscope was used to observe the osseointegration around the micro-implants.ELISA was employed to detect TNF-α in the gingival crevicular fluid around the implants.Results:The FHA-coating titanium alloy orthodontic micro-implants led to higher bone density,smaller marrow cavity,and lower TNF-α level and shorter lasting period of TNF-α over-expression than the controls (P < 0.05).Conclusion:The FHA-coating titanium alloy orthodontic micro-implant has better histocompatibility and may inhibit peri-implantitis.

Molecules can enter the nucleus by passive diffusion or active transport mechanisms, depending on their size. Small molecules up to size of 50-60 kDa or less than 10 nm in diameter can diffuse passively through the nuclear pore complex (NPC), while most proteins are transported by energy driven transport mechanisms. Active transport of viral proteins is mediated by nuclear localization signals (NLS), which were first identified in Simian Virus 40 large T antigen and had subsequently been identified in a large number of viral proteins. Usually they contain short stretches of lysine or arginine residues. These signals are recognized by the importin super-family (importin α and β) proteins that mediate the transport across the nuclear envelope through Ran-GTP. In contrast, only one class of the leucine-rich nuclear export signal (NES) on viral proteins is known at present. Chromosome region maintenance 1 (CRM1) protein mediates nuclear export of hundreds of viral proteins through the recognition of the leucine-rich NES.

Objective To determine prevalence of dementia in diabetics and non-diabetics, and in different age and gender groups. Methods A case-control study was conducted among participants aged 50 and over in Jing' an temple community in Shanghai. Subjects in diabetics group were matched to non-diabetics groups for age and sex with 1:1 matching. Personal information and case history were collected through questionnaire. The subjects were screened for dementia using the Mini Mental State Examination (MMSE). Subjects that screened positively (indicated by an MMSE score below 19, 21 and 24 among those with illiteracy, elementary school and above junior middle school education, respectively) were subsequently examined by a series of neuropsychological tests. Based on all available information, a diagnosis of dementia was defined according to the Diagnostic and Statistical Manual of Mental Disorders ( DSM )-Ⅳ criteria Results Prevalence of dementia of 4. 75% (23/484, 95% CI: 3. 03%-7.04%) in diabetics was higher than that of 2. 24% (11/490,95% CI: 1.13% -3.98%) in non-diabetics (X~2 = 4.54, P=0.03).Prevalence of dementia among diabetics in age groups of 60-69, 70-79 and 80 and above was 1.94% (2/103), 4. 43 % (9/203) and 14.12% (12/85, trend X~2 =18.04, P <0.01), and in non-diabetics was 1.43% (2/140), 2. 86% (6/210) and 5.00% (3/60, trend X~2 = 4.58, P=0.03), respectively.Prevalence of dementia among female and male in diabetics was 6.55% (19/299) and 2.06% (4/194) (X~2 = 5.18, P = 0.02), respectively, and in non-diabetics was 3.01% (9/299) and 1.05% (2/191).Conclusions Prevalence of dementia is significantly higher in diabetics than in non-diabetics, higher in women than men, and increases as age rises.

Objective To investigate the conversion rate of subtypes of amnestic mild cognitive impairment (aMCI) to Alzheimer' s disease (AD) and assess the contribution of neuropsychological disturbance in progression from MCI to AD over 2 years. Method Subjects from memory clinic of Huashan hospital including 130 of who met the operational criteria for Mayo Clinic defined aMCI by neuropsychological tests covering global cognitive function, executive function, memory function, language function and visual spatial skills. They underwent multidimensional assessment and a neuropsychological battery at baseline and at follow-up, after about 2 years. Diagnosis for dementia was based on National Institute of Neurological and Communicative Disorders and Stroke; Alzheimer' s Disease and Related Disorders Association (NINCDS-ADRDA) criteria. Results Forty-four cases of 130 (33. 8% ) elder people with aMCI converted to probable AD with 17 aMCI-s and 27 aMCI-m subjects within an average 23.8 (6. 8 ) months. There was significant difference between the reversion rate of aMCI-s and aMCI-m (26. 2% vs 42. 9%, x2 = 3.957,P = 0. 047). Moreover, as the disease progressing,the two groups declined similarly in memory and executive function while in the aMCI-s group, the function of spatial structure relatively reserved in aMCI-s but function of language and attention diminished faster, and in the aMCI-m group, the ability of spatial structure declined even more significantly. Conclusion The aMCI-m is more likely to progress to AD than aMCI-s and it' s necessary to divide aMCI into aMCI-s and aMCI-m to help determine prognosis.

BACKGROUND:It is presumed that urinary trypsin inhibitor could have protective effects on local and systemic tissues and could inhibit osteoclast proliferation and activation under long-term chronic inflammation conditions and in ischemic and anoxic environment which was induced by prosthetic wear. OBJECTIVE:To investigate the inhibitory effect of ulinastatin on receptor activator for nuclear factor-κb ligand-induced differentiation, proliferation and osteoclastogenesis of RAW264.7 cells and its effects on matrix metal oproteinase-2, matrix metal oproteinase-9 expression level and activity. METHODS:Mouse monocyte/macrophage cellline RAW264.7 was treated with different concentrations of urinary trypsin inhibitor (0, 500, 5 000 U/mL) for 24, 48 and 72 hours. Experiments were divided into four groups:the blank group (RAW264.7 cells), receptor activator for nuclear factor-κb ligand-induced group (0 U/mL ulinastatin), 500 U/mL ulinastatin group and 5 000 U/mL ulinastatin group. RESULTS AND CONCLUSION:(1) MTT results indicated that there was no significant difference on the proliferation of RAW264.7 cells treated with urinary trypsin inhibitor at 0-5 000 U/mL (P>0.05) (2) Tartrate-resistant acid phosphatase staining results revealed that compared with receptor activator for nuclear factor-κb ligand-induced group, the number of tartrate-resistant acid phosphatase-positive cells was significantly less in the ulinastatin group (P<0.05), showing a time-dose dependent manner. (3) Immunohistochemisical results found that compared with receptor activator for nuclear factor-κb ligand-induced group, the percentage of matrix metal oproteinase-9-positive cells was apparently lower in the ulinastatin group. (4) Western blot assay results demonstrated that matrix metal oproteinase-9 expression was low in the RAW264.7 cells alone. At 48 hours after addition of receptor activator for nuclear factor-κb ligand, matrix metal oproteinase-9 protein expression was large. At 72 hours after culture in the 5 000 U/mL ulinastatin group, matrix metal oproteinase-9 protein expression was evidently reduced. (5) Gelatin zymography results showed that compared with the receptor activator for nuclear factor-κb ligand-induced group, matrix metal oproteinase-9 expression was significantly lower in the 5 000 U/mL ulinastatin group (P<0.05). Results suggested that urinary trypsin inhibitor inhibited receptor activator for nuclear factor-κb ligand-induced osteoclastogenesis and diminished matrix metal oproteinase-9 expression and activity.
