Objective To compare the clinical outcomes of Bryan disc replacement with anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylopathy. Methods Sixteen patients underwent Bryan cervical disc replacement (A group), and 35 patients underwent traditional ACDF (B group) were included in the study. Patients were followed up at regular intervals. The JOA score, SF-36, neck disability index (NDI) score and the dynamic flexion-extension radiographs were used to evaluated the oucomes.Results All the patients were followed up for more than 6 years (mean, 73.5 months). There were no severe adverse events in both groups. In A group, there were no differences between postoperative and preoperative mobility of surgical segments (P＞0.05). All patients obtained bone fusions 6 month after surgery in group B.In both groups, the clinical symptoms relieved obviously after surgery. The postoperative scores of the JOA,SF-36 and NDI significantly improved compared with those of preoperative ones (P＜0.05). In B group, range of motion (ROM) was significantly decreased postoperatively (P ＜0.01); in A group, there were no significant differences between postoperative and preoperative ROM (P＞0.05). The difference between two groups regarding ROM was noted (P＜0.05). Conclusion The mid-term outcomes of Bryan cervical arthroplasty are satisfied. And the cervical arthroplasty which can maintain the mobility of the segment, and decrease the incidence of the postoperative neck axial symptoms is a viable alternative to cervical spondylopathy.

Objective: To investigate applicability for Boston naming test (30 items) (BNT) in Chinese elderly and identify effect for mild cognitive impairment (MCI) and Alzheimer's dementia(AD) using BNT. Methods:100 normal elderly, 38 amnesic MCI, 34 mild AD and 38 moderate AD were evaluated by neuropsychological tests (include BNT, mini mental state examination and auditory verbal memory test, etc). MMSE total score of 4 groups were 28.4?1.5, 26.1?2.6, 20.7?1.7, and 15.6?3.3, respectively. Results: Age, sex, level of education were found to be significant factors affecting overall scores of spontaneous naming in normal elderly group. Spontaneous naming score for participants of elementary, high school and college groups were 22.2?3.3, 25.5?2.5 and 26.3?1.8, respectively. Scoring of male participants higher than that of females. Spontaneous naming score of 4 groups were 24.9?3.0, 20.9?3.6, 18.7?4.0 and 15.7?4.2, respectively. As cut-off ≤22 score of spontaneous naming of BNT, the sensitivities for MCI, mild AD and moderate AD were 61%, 79% and 95% respectively; the specificities were all around 81%. Selective impairment of unfamiliar items occurred MCI and mild AD and hold of familiar item across diagnostic groups. Semantic cue naming and recognition ability by BNT showed there was progressive damage in AD patients, but less than that of spontaneous naming of BNT. Conclusion: The ability of naming is influenced by age, gender and educational level. Patients with MCI or mild AD have impairment in naming.

Objective To analyze the characteristics of auditory verbal memory impairment in mild Alzheimer's Disease (AD) and Mild Cognitive Impairment (MCI).Methods Auditory verbal memory test was performed in 72 patients with MCI,45 patients with mild AD,and 62 normal controls.Results Significant intergroup differences were found in total former five free recall and learning scores,The MCI subjects( 16.4?5.5,2.6?1.7)performed significantly more poorly than the normal control subjects(NC) (30.2?5.6,3.4?1.9),and mild AD categories (9.8?4.1,2.0?1.2) showed lower results than the MCI subjects(t=2.26,P

Objective To investigate the influence factors of quantitative changes of dendritic cells (DC) in neonate born to HBsAg positive mother.Methods Sixty HBsAg positive mothers and their newborns were enrolled from the Third People's Hospital of Taiyuan from July 2011 to March 2012.The serum hepatitis B virus (HBV) markers and HBV DNA in mothers and newborns before vaccination were determined by chemiluminescence immunoassay (CLIA) and fluorescence quantitative polymerase chain reaction (PCR).The circulating frequencies of DC subsets were determined in the newborns by flow cytometry (FCM).The comparison of data was done by Mann-Whitney test and t test.The correlation analysis was done by Spearman rank correlation analysis and chi square test.Results Among 60 newborns,5 were HBsAg positive and HBV DNA negative.Among 60 HBsAg positive mothers,21 were HBeAg positive and 29 were HBV DNA positive.There was no significant quantitative difference of neonatal myeloid dendritic cells (mDC) and plasmacytoid dendritic cells (pDC) between intrauterine infection group and intrauterine non-infection group (Z=-0.535,P=0.59 and Z=-0.027,P=0.98,respectively).However,mother's HBeAg positive status was closely related with neonatal HBeAg positive status (Pearson contingency coefficient was 0.928,P＜0.01).The frequencies of mDC in newborns born to HBeAg positive mothers were significantly lower than those born to HBeAg negative mothers (0.60±0.57 vs 0.87±0.58; Z=-2.085,P＜0.05).However,there was no significant quantitative differences of mDC and pDC between newborns born to HBV DNA positive mothers and born to negative mothers (Z=-1.272,P=0.20 and Z=-0.806,P=0.42,respectively).The frequencies of pDC were significantly lower in newborns born to mothers with HBV DNA＞ 1 × 107 copy/mL compared to newborns born to HBV DNA negative mothers (0.30±0.18 vs 0.64±0.55; t=-2.996,P=0.005).Conclusions HBeAg positive status of mothers may reduce neonatal frequencies of mDC.Neonatal frequencies of pDC may be reduced when the mothers' HBV DNA loads are more than 1 × 107 copy/mL.

BACKGROUND: Gastrodin (GAS) is widely used as adjuvant therapy for vertigo, headache and hypertension. However, it is recently noticed that GAS might be used as an agent for treating obesity.OBJECTIVE: To set up obese rats of high-fat diet to observe the effects of different concentrations of GAS on body mass and serum metabolite levels and to analyze its possible mechanism.DESIGN: A randomized and controlled animal experiment.SETTING: Institute of Physiology and Psychology, School of Basic Medical Science, Lanzhou University.MATERIALS: This study was performed at the Institute of Physiology and Psychology, School of Basic Medical Science, Lanzhou University and Gansu Provincial Key Laboratory of Pre-clinical Study for New Drugs from June to August in 2007. Forty-four healthy one-week-old male SD rats, weighing (99.57±2.13)g, were purchased from Shanghai SILAIKE Laboratory Animal Co., Ltd. Disposal of animals was in accordance with the animal ethics standards. Basic animal feed was provided by Suzhou Shuangshi Laboratory Animal Feed Science and Technology Co., Ltd. High-fat forage were self-made in the authors' laboratory. Each 100 gram of high-fat forage consisted of basic feed (57.5g), egg yolk powder (11.79g), lard (10g), pig bile salt (0.2g), casein (7g), milk power (13g), salt(0.085g), and yeast powder (0.425g), and the 100 gram of high-fat forage contained of fat (22.07g), protein (23.7g), carbohydrate (39g), and quantity of heat (472.16 calorie). GAS (98% in purity) was purchased from Shaanxi Xuhuang Botanical Science & Technology Development Co., Ltd. Malondialdehyde (MDA) and total antioxidative capability (T-AOC) kits were purchased from Jiancheng Bioengineering Institute, Nanjng, Jiangsu Province.MAIN OUTCOME MEASURES: The body mass was measured every seven days. The food intake in each group was monitored in every morning. At the end of the experiment, femoral artery blood samples were collected to determine the blood glucose, the serum levels of MDA, T-AOC, Insulin, free fatty acid (FFA), glutamate-pyruvate transaminase (GPT), glutamic oxalacetic transaminase (GOT) and blood lipid profile. Insulin resistance index (IRI) and insulin sensitivity index (ISI) were calculated as IRI=(FBG×FINS)/22.5 and ISI=1/(FINS×FBG).RESULTS: All 44 rats were included in the final analysis. Body mass: The body mass in the HFFC group was significantly higher than in the NC group from 4th-8th weeks (P＜0.01), while the body mass in GAS groups was lower compared to HFFC group (P＜0.05-0.01). There were no significant differences among the GAS-H, GAS-M, and GAS-L groups (P＞0.05). Therefore, GAS had no dose-dependent relationship in inhibiting the body mass of obese rats of high-fat diet. Caloric intake: The caloric intake was significantly higher in the HFFC group than in the NC group (P＜0.01), and was significantly decreased in GAS group compared to NFFC group from the 4th week (P＜0.05-0.01). Serum levels of MDA, T-AOC, GPT and GOT: The serum level of T-AOC was decreased and that of MDA, GPT were increased significantly in the HFFC group compared with NC group (P＜0.01, P＜0.05). In the GAS-L group, T-AOC, level was significantly increased and MDA level was significantly decreased compared to HFFC group (both P＜0.01). Levels of blood glucose and insulin: In the HFFC group, blood glucose level and IRI were significantly increased, and ISI was obviously decreased compared to NC group (P＜0.05-0.01). In the GAS-L group, blood glucose level and IRI were significantly decreased, and ISI was significantly increased compared to HFFC group (P＜0.05-0.01). FFA and lipoprotein cholesterol levels: In the HFFC group, FFA and low-density lipoprotein cholesterol levels were increased and high-density lipoprotein cholesterol level was decreased compared to NC group (P＜0.05-0.01).CONCLUSION: GAS may play an important role in inhibiting rats' body mass of high-fat diet. The mechanism of action may be related to GAS regulating the metabolism of blood glucose and FFA, improving IRI and elevating T-AOC.

Objective To establish the bedside screening scale for cognition examination in systemic lupus erythematosus patients.Methods The modified mini-mental status examination(MMMSE)(revised by the Neurology Department of Hua Shan Hospital)was applied to examine the recognition function of SLE pa- tients.The results were compared with those of the traditional mini-mental status examination(MMSE).Results MMSE examination results showed that NPSLE score was lower than that of normal control group(P＜0.01),no significant difference was found between NPSLE patients and SLE control group(P＞0,05),and the completion time was longer than SLE control group and normal control group(P＜0.01);but no significant difference was found between SLE control group and normal control group.The result of MMMSE examination showed that the score of NPSLE group was lower than that of SLE control group and normal control group(P＜0.01),and the completion time was longer than SLE control group and normal control group(P＜0.01);but the score of SLE control group was lower than the normal control group,and its completion time was longer than normal control group,the difference was statistically significant(P＜0.01).Conclusion MMSE is the most widely used dementia scale,but it is not sensitive in demonstrating the impairment of recognition function.The several items we added to the MMMSE can detect recognition impairment more sensitively,and ean be very easily applied,costs less time(within 10 minutes).Therefore,it can be used for SLE bedside screening.

Paracetamol was used as a model drug in this study to investigate the synergetic effects of lipid coating and beta-cyclodextrin (beta-CD) inclusion for masking the bitter taste of poorly soluble drugs. To control the concentration as low as possible of the free drug which produced a bitter taste, a kinetic model was established to calculate the drug distribution theoretically among the free drug in medium, lipid coated particles and molecular inclusion on the basis of the preparation and characterization of the lipid microspheres, so as to select the proper amount of beta-CD. Finally, the synergetic drug delivery systems were prepared and characterized by 1H nuclear magnetic resonance (1H NMR), molecular simulation and the electronic tongue. As a result, the drug release rate constant (k) of the lipid microspheres coated with octadecanol was determined as 0.001 270 s(-1). Then, the synergetic drug delivery systems were prepared with the ratio of 6.74 : 1 (w/w) for beta-CD and paracetamol. The chemical shift values for the fingerprint peaks of paracetamol all increased and hydrogen bonds were formed between the oxygen on the phenolic hydroxyl group, the nitrogen on the imino in paracetamol and the hydrogens on the hydroxyl groups in beta-CD. The results tested by the electronic tongue indicated that the paracetamol, lipid microspheres, beta-CD inclusion and their mixture showed different taste characteristics, with the bitterness order of the synergetic drug delivery systems approximately lipid microspheres < beta-CD inclusion < paracetamol, which confirmed the synergetic taste masking effects of lipid coating and beta-CD molecular inclusion. In summary, the synergetic taste masking was jointly achieved through the retard of the drug release by the lipid coating and the inclusion of the free paracetamol by beta-CD through hydrogen bonds.
