Objective To investigate the impact of glucose metabolism-related protein 1 (GMRP1) on the regulation of c-Myc gene transcription, to establish GMRP1 gene knockout mouse model, and to study the influence of GMRP1 on glucose metabolism. Methods Chromatin immunoprecipitation-PCR (ChIP-PCR) was utilized to screen out the genes transcriptionally regulated by GMRP1. Luciferase reporter system was applied to assay the regulation of c-Myc promoter activity by GMRP1. GMRP1 knockout mice were constructed and validated by PCR and western blotting. Body weight and random blood glucose were measured in both knockout and wild type mice fed with either chow diet or high-fat diet. The levels of glucose metabolism in mice of 20 or 28 weeks old were evaluated by intraperitoneal glucose tolerance test. Results GMRP1 was capable of binding to the promoter of c-Myc gene and activating the expression of c-Myc gene. There were no significant differences in body weight, random blood glucose or glucose tolerance between GMRP1-deficient and wild type mice fed with either chow diet or high-fat diet (all P > 0.05). Conclusion GMRP1 may activate the transcription of c-Myc gene. GMRP1 deficiency exerted no significant effects on mouse glucose metabolism.

Objective To compare the theory of mind(TOM) abilities between autistic children's parents and the normal children' s,and to indirectly prove that TOM deficit in autism maybe related to heredity in cognitive neuropsychology.Methods This study examines TOM abilities in 32 autistic children' s parents and 32 normal children' s parents,using the computerized Yoni task and an extensive battery of neuropsychological tests.Results In contrast to findings in the control group,autistic children' s parents showed significantly lower scores in affective theory of mind( (23.06 ±5.12)vs(25.63 ±4.47),P＜0.01 ) and special emotion( ( 10.13 ±4.14)vs ( 14.87 ±2.21 ),P＜0.05),but not in cognitive theory of mind( (22.75 ±5.01 ) vs(22.56 ±5.63),P＞0.05).Conclusion The autistic children' s parents are impaired in affective theory of mind,and to indirectly prove that autistic TOM deficit maybe related to heredity in cognitive neuropsychology.

Objective To explore the activity and its possible neural mechanism of brain default mode network by using resting state functional magnetic resonance imaging (fMRI) in patients with mild cognitive impairment (MCI). Methods The 20 amnestic MCI patients and 25 healthy controls were included in this study, and all subjects underwent mini-mental state examination (MMSE), auditory verbal learning test (AVLT) and fMRI. The data were analyzed by amplitude of low frequency fluctuation (ALFF), and the enhanced and weakened regions of ALFF were observed and compared in both MCI patients and healthy controls. Results MMSE and AVLT tests showed that the memory function was seriously impaired in MCI patients compared with healthy controls, which is based on the short and long delayed episodic memory impairment (2.4±1.7 vs. 6.6±1.4, t=3.70, P＜0.01; 2.1±1.6 vs. 6.7±1.5, t=4.16, P＜0.01). The resting state fMRI showed that MCI patients had significant decreases of ALFF in hippocampal formation, parahippocampal cortex and lateral temporal cortex as compared with health controls (t=2.58, 2.43 and 1.75, all P＜0.01), which were closely relevant to the episodic memory. And they had significant increases in temporal-parietal joint and inferior parietal lobule (t=3.14 and 2.77, both P＜0.01). Conclusions MCI patients show significant decreased active intensity of some DMN nodes that is related to episodic memory in resting state. Increased active intensity in MCI patients would be some type of compensation.

Objective To set up and verify a new scoring system of clock drawing test(CDT).Methods CDT and other neuropsychological tests were applied to 180 normal individuals.170 subjects with mild cognitive impairment(MCI),and 31 patients with mild Alzheimer's disease(AD).The first step of the 30-score system of CDT was to anchor the 4 points of"12-3-6-9".totaling a score of 4 which was the "30-score system A(Anchoring)part";and the other 13 items reflecting the drawing results and totaling a score of 26 made up the so called"30-score system C(Clockfaee)part".the two together had a total score of 30.Thirty-eight subjects underwent Xe-enhanced computed tomography(Xe-CT)scanning for quantitively measuring regional cerebral blood flow(rCBF)of 26 regions of brain.Results Correlations coefficients of the scores of 14 items with the total score in 30-score system of CDT were in the range of 0.48to 0.71(P＜0.01).30-score system C part was closely correlated with indicators of visuospatial and executive function,while 30-score system A part with memory indicators.The sensitivity and specificity of the 30-score system A part score≤2 for detecting MCl were 70.6%and 73.9%.respectively.The sensitivity the specificity of 30-score system C part score≤17 for mild AD were 75.3%and 75.9%.respectively.In the regression equation of 30-score system A and C part.the combined independent variables were the CBF of left frontal cortex and right white matter,respectively.Conclusion The 30-score system A and C part have difierent meanings:30-score system C part could be used to identify AD while 30-score system A part is helpful for identiring MCI.

OBJECTIVEThe aim of this paper is to introduce the clinical and laboratory procedures of fabricating silicone gingival epithesis and evaluate the long-term effects of the epithesis.

METHODSFlexible gingival epithesises were fabricated by the same way of fabricating partial denture, and their effects were evaluated in 31 patients by following up for 8-20 months.

RESULTSPatients' responses to appearance showed that their esthetic appearance had been much improved in all of the patients and the comfort and retention of their epithesises varied from good to excellent in almost all the patients. Discoloration of the epithesises was noticed by the patients within ten months in average. Doctors' examination confirmed patients' responses, and caries was detected at the necks of teeth covered by epithesises and slight gingivititis was discovered in the area under the epithesises in two cases.

CONCLUSIONFlexible gingival epithesis is a simple and effective method for correcting gingival recession, and the fabrication is simple and don't need special equipment. However, discoloration of the epithesis remains a problem.

Objective To compare the clinical efficacies of vasiculation moxibustion with pastes prepared in different ways and at different acupoint groups in treating allergic rhinitis due to deficient cold of lung qi. Method Eighty subjects were randomized into 4 groups, 20 in each group. Raw Bai Jie Zi (Semen Brassicae) was used in the vesiculation paste for group 1 and 2;stir-baked Bai Jie Zi (Semen Brassicae) was used for group 3 and 4. In group 1 and group 3, bilateral Feishu (BL 13), Fengmen (BL12), and Gaohuang (BL 43) were selected; in group 2 and group 4, bilateral Dazhu (BL11), Geshu (BL17), and Shenshu (BL23) were selected. The symptom and sign scores were compared before and after intervention. Result There were significant differences in comparing the symptoms and signs among the four groups (P＜0.05), and paired comparisons showed that the therapeutic efficacies of group 1 and group 3 were significantly higher than that of group 2 and group 4 (P＜0.05), while the differences in the therapeutic efficacy between group 1 and group 3, group 2 and group 4 were statistically insignificant (P>0.05). Conclusion Vesiculation moxibustion at the point group of Fengmen (BL12), Feishu (BL13), and Gaohuang (BL43) can markedly improve the symptoms and signs of allergic rhinitis due to deficient cold of lung qi;raw and stir-baked Bai Jie Zi (Semen Brassicae) can work equally in vesiculation paste for allergic rhinitis.

Objective:To explore the effect and difference of percutaneous coronary intervention (PCI) and medical therapy on quality of life and cognitive function in patients with coronary heart disease (CHD),and to investigate the relationship between quality of life and cognitive function.Methods:A total of 320 patients with CHD,who underwent coronary angiography and PCI (PCI group,n=160),or underwent coronary angiography and medical therapy (drug therapy group,n=160),were selected.The quality of life was assessed by using the Health Survey Form SF-36 (SF-36) and the Seattle Angina Questionnaire (SAQ),and the cognitive function was assessed by using the Mini-Mental State Examination (MMSE).General data of patients were collected on the day of coronary angiography.Telephone follow-up was conducted in 1 month after treatment,and the outpatient review was carried out in 3 and 6 months after treatment.Results:A total of 309 valid questionnaires were collected.The scores of quality of life in the PCI group and the drug therapy group after treatment were both increased compared with those before treatment (both P＜0.05).The SF-36 scores of four dimensions (role physical,bodily pain,vitality and mental health) in the PCI group were all significantly greater than those in the drug therapy group (all P＜0.05).The SAQscores of two dimensions (angina stability and angina frequency) were both higher in the PCI group than those in the drug therapy group in 6 months of post-operation (all P＜0.05).There was no significant difference in cognitive function before and after the treatment in the 2 groups (P＞0.05).There was no significant difference in cognitive function between the PCI group and the drug therapy group (P＞0.05).In the PCI group,physical function,role physical,bodily pain,and role emotional were positively correlated with cognitive function (r=0.207,0.182,0.184,0.176 respectively,all P＜0.05).In the drug therapy group,there was no correlation between quality of life and cognitive function.Conclusion:The quality of life for the patients is improved in the PCI group and the drug therapy group,but the improvement degree in the PCI group is more obvious.Both PCI and drug therapy do not result in the decrease of cognitive function,and there is no difference between the 2 groups.There is positive correlation between quality of life and cognitive function in the PCI group,there is no correlation between quality of life and cognitive function in the drug therapy group.

Brain natriuretic peptide (BNP), a natriuretic peptide hormone, is mainly secreted by cardiomyocytes when they are pulled by mechanical force. BNP acts to increase natriuresis and decrease vascular resistance, thereby decreasing blood volume, systemic blood pressure and afterload. It is not only the main indicators of cardiac function which is widely used in clinical, recent studies have also shown that it has a very important value in identifying sudden cardiac death(SCD). However, the exact expression of the regulation mechanism is still unknown. This paper reviewed the structure, expression of the regulation mechanism of BNP, and the application progress in clinical and forensic.

Objective Our purpose was to investigate the pathogenic gene mutation of a Han Chinese family with vitreous amyloidosis.Methods The 9 individuals(proband,1 affected member and 7 unaffected members) of the family were selected and their DNA was extracted from peripheral blood.The 4 exons of transthyretin(TTR) gene were amplified by polymerase chain reaction(PCR) technique.The amplified products of TTR gene were sequencing by Sanger technique.We also selected 100 unrelated healthy individual as the control group.Results By DNA sequencing,a heterozygous mutation was found in 4 of the 9 subjects from the family.The transition of adenine to cytosine(AAG ＞ ACG) was detectable in exon 2 of TTR,which changed the amino acid composition at codon 35 (Lys35Thr).This mutation did not presented in control group.Conclusion The heterozygosis mutation of TTR gene Lys35Thr should be a pathogenic mutation for the family with vitreous amyloidosis.
