Type 1 diabetes mellitus and autoimmune thyroid disorders are the most common combination of autoimmune polyendocrine syndrome type Ⅲ(APS Ⅲ). However, APS Ⅲ combined with myasthenia gravis is rare. We described a male patient with myasthenia gravis, type 1 diabetes mellitus, and Hashimoto thyroiditis, who was diagnosed as APS Ⅲ. The human leukocyte antigen (HLA)type was analyzed in this patient. We subsequently reviewed 11 cases of APS Ⅲ combined with myasthenia gravis. This review revealed that HLA-DR9/DQ9 might be a specific HLA subtype associated with APS Ⅲ and complicated with myasthenia gravis .

Objective To evaluate the value and accuracy of M-mode color Doppler echocardiography for detecting left ventricular diastolic function in patients with cardiac disease. Methods The rate of left ventricular filling flow propagation (Vp) and the early -diastolic peak velocity of the mitral annulus(E) was measured in normal subjects(n=40)and in patients with cardiac disease (n=40). All the patients had abnormal left ventricular diastolic function confirmed by isotope-angiography test. Results ① The Vp was significantly lowered in patients with cardiac disease than in normal subjects(P

Objective The incidence rate of acute pancreatitis in pregnancy (APIP) is on the rise, and yet there is no effec-tive method for its prevention and treatment .This study aimed to investigate the high risk factors of APIP and its prognostic evaluation index. Methods We retrospectively analyzed the clinical data of 35 cases of APIP ( group A) and another 35 cases of acute pancre-atitis in non-pregnancy as controls (group B).We compared the etiologic factors of acute pancreatitis , changes of laboratory indexes after onset of the disease , and clinical outcomes between the two groups . Results No statistically significant differences were found in the risk factors between the two groups (χ2 =0.233, P>0.05).Serum cholesterol and triglyceride levels were remarkably higher in group A ([15.69 ±7.71] and [15.54 ±7.82] mol) than in B ([5.07 ±2.95] and [3.82 ±2.58] mol) (P<0.05).There were significant differences between groups A and B in WBC count ([19.00 ±5.31] vs [14.98 ±9.77] 109/L), Hb ([82.77 ±11.77] vs [101.77 ±1.50] g/L), and serum Glu ([8.77 ±2.76] vs [6.23 ±1.99] mol/L)(P<0.05).Multivariate logistic regression a-nalysis showed the predictive value of cholesterol and triglyceride levels for APIP and a correlation of WBC and Hb with the clinical out -comes of the patients.The in-hospital mortality rate was significantly higher in group A than in B (χ2 =3.968, P=0.046), and so was the incidence rate of severe acute pancreatitis (χ2 =5.510, P=0.019). Conclusion Biliary diseases are the main high risk factors of APIP, followed by hyperlipidemia .Triglyceride and cholesterol levels have the predictive value for APIP .The WBC count and Hb level can be used to assess the patients′condition and predict the clinical outcomes .

In the modernization course of Chinese materia medica(CMM),two misunderstanding mistakes which are out of line with traditional Chinese medicine(TCM)theory and excessively emphasize the research of CMM compound prescription and two difficult points which are the establishment of CMM quality control system and the establishment of CMM evaluation system were pointed out.Because the main means of TCM syndrome differentiation treatment and TCM combination therapy is CMM processing pieces and the starting point of the research of CMM efficacy substantial basis should be CMM processing pieces,the priority of the modernization of CMM should be the research on modern CMM processing pieces and the conditions have been mature now.The research on modern CMM pieces were supposed to take three steps:the research on "standardized extract",the research on "effective fraction" and the research on the CMM nature of "effective fraction".

Single factor analysis results were indicated that the scores of QOL between the different gender, occupation, marital status age,education were remarkable difference(all P

Objective To investigate the effect of placenta derived tumor necrosis factor (TNF)-α and myostatin (MSIN) in patients with preeclampsia (PE) and fetal development.Methods One hundred and twenty pregnant women who delivery from October 2008 to October 2013 were enrolled in this study.In them,40 healthy pregnant women was normal control group,40 PE and fetal growth in normal pregnant women was PE group,40 PE and fetal growth restriction (FGR) of pregnant women was PE + FGR group.The immunohistochemical localization of SABC method was used to detect for TNF-α and MSIN protein in placenta tissue in each group respectively.Real-time fluorescent quantitative PCR and Western blotting were used to detect for TNF-α and MSIN mRNA and protein in placenta tissue.Results The TNF-α mainly located in placental blood vessels surrounding stroma,decidual cells,trophoblastic cells and MSIN mainly located in placental blood vessels surrounding stroma,decidual cells and terminal villi.The TNF-α and MSIN mRNA expression quantity in PE group was 3.65 ±0.86,1.80 ±0.32 ; in PE + FGR group was 3.88 ± 0.71,2.01 ± 0.55 ; in normal control group was 1.32 ± 0.21,0.77 ± 0.39.The TNF-α and MSIN mRNA expression quantity in PE group and PE + FGR group were significantly higher than those in normal control group(P ＜ 0.01),and there were significant differences between PE group and PE + FGR group(P ＜ 0.05).The TNF-α and MSIN protein expression in normal control group was 0.56 ±0.13,1.31 ± 0.23;in PE group was 1.67 ±0.25,1.55 ±0.34 ;in PE + FGR group was 2.78 ±0.41,3.07 ±0.51.The TNF-α and MSIN protein expression in PE group and PE + FGR group were significantly higher than those in normal control group(P ＜ 0.01),and there were significant differences between PE group and PE + FGR group(P ＜ 0.05).Conclusions The placenta derived TNF-α and MSIN have more important roles in the pathogenesis of PE and normal development of fetal.It can provide coping strategies by detecting the level of placenta derived TNF-α and MSIN.

The prevalence of violence behavior in patients with schizophrenia is higher than that in common population. Data suggest that genetic factors may play a substantial role for the etiology of the behavior. Among the particular gene polymorphisms that have been considered to be involved in violence behavior, the catechol-O-methyltransferase (COMT) gene had been the focus of recent research. This article reviews the association research between COMT gene and violence behavior in patients with schizophrenia in several aspects: SNP polymorphism of COMT Val158Met and COMT Ala72Ser, haplotype of COMT gene and DNA methylation of promoter region of COMT gene. The genetic research direction is presented for patients with schizophrenia.

Objective To investigate the influence of indenter diameter on fracture strength and fracture mode of IPS e. max all-ceramic crowns using mechanical experiments and three-dimensional finite element (3-DFE) method, to validate the 3-DFE model using mechanical experiments, and to provide a guideline for occlnsal surface design for IPS e. max all-ceramic crowns. Methods A 3-DFE model of an all-ceramic crown on a molar was established using ANSYS10.0 software. The 3-DFE crown was loaded occlusally at three points to simulate the contact points of a hemispherical indenter loading on the crown. Two indenter diameters (4 mm and 10 mm) were designed by changing loading point, load level and its direction. The stress distribution and the principal stress in the 3-DFE model were calculated. Meanwhile, IPS e. max ceramic crowns were made on a laboratory model and loaded with indenters. The diameters of the indenters were also 4 mm and 10 mm respectively. Fracture mode and fracture-resistance of the crowns were recorded. Results The principal stress increased as load increases for both small and large indenters. Stress concentrated in the central fossa of the 3-DFE crown when loaded with the small indenter. Stress concentration appeared in the middle area of the occlusal surface mesio-distally when 3-DFE crown was loaded with large indenter. The fracture-resistance load was 600 N to 700 N for 4 mm diameter indenter, and 2500 N to 2750 N for 10 mm diameter indenter. Mechanical experiments indicated the same results as those from 3-DFE analysis. Conclusions Both the three-dimensional finite element analysis and the mechanical experiment showed the same results. When loaded with 4 mm diameter indenter, fracture occured in the central fossa of the crown, however, 10 mm diameter indenter usually caused extensive crown damage.

Background and purpose: Magnetic resonance spectroscopy is currently the only non-invasive magnetic resonance imaging technique which can detect metabolite composition of live organ and tissue and also conduct semi-quantitative or quantitative analysis. We analyzed the characteristics of metabolic changes among normal liver, cirrhosis regenerative nodule and liver cancer on the background of cirrhosis by voxel proton MR spectroscopy at 1.5 Tesla. Methods: 20 healthy volunteers (control group), 25 cirrhosis (cirrhosis group) and 23 hepatocellular carcinoma after cirrhosis (HCC group) patients were our candidates. The characteristics of spectra of ~1H-MRS were observed. The height and ratio of choline complex (Cbo) and lipid methylene (Lip2) were recorded and the results were compared among the groups. Results: The success rate of ~1H-MRS was about 88.2% (60/68). There were statistically significant differences among the heights of Lip2 peak of the three groups, and also between that of the control group and the group of liver cancer. But there were no significant differences between that of control group and cirrhosis group, cirrhosis group and liver cancer group. The comparison of the height of Cho peak and the ratio of Cho/Lip2 showed statistically significances both among the three groups and between each other. Conclusion: The metabolic changes of the liver could be shown non-invasively by ~1H-MRS, which could be useful for differential diagnosis or diagnosis of cirrhosis regenerative nodule and HCC.

BACKGROUND: The death of aging cells is virtually apoptosis. To a certain extent, it can be interpreted as a series of results of gere activities.Therefore, the inhibition of oncogene's expression can lengthen the life span of cells and delay aging of brain tissues.OBJECTIVE: To study the effect of abstragulus mongholicus bung (AMB) on apoptosis of nerve cells and the expression of relevant gene in aging mice brain.DESIGN: Completely randomized design and controlled experiment.SETTING: Department of Biochemistry, School of Basic Medical Sciences of Jiamusi University.MATERIALS: The experiment was conducted at the Experimental Animal Center and Biochemical Laboratory of Jiamusi University from December 2003 to May 2004. Totally 24 healthy Kunming mice were recruited in this study. There were 8 two-month-old mice (young group) and 16 twelve-month-old mice. All the 16 mice were randomized into abstragulus mongholicus bung group and old control group with 8 in each group.METHODS:① AMB group:Mice in AMB group received gastric gavage was provided by the Department of Traditional Chinese Medicine of the First Hospital Affiliated to Jiamusi University, and evaluated by Jiamusi Drug Inspection Bureau. Water decoction was prepared with 2 kg/L raw materials. Mice in old control group and young group were filled with lukewarm boiled water.② All the animals were treated as above for 30 consecutive days before put to death. Their brains were taken out immediately and the middle parts of the brains were removed to fix with neutral formaldehyde. The remaining brain tissues were made into mitochondria suspension. Content of manganese superoxide dismutase (Mn-SOD) and malondialdehyde (MDA) was determined with xanthosine oxidase method and TBA chemical colorimetry. Apoptotic cells (cells with yellow nuclei were positive ones) were assayed with in situ end-labeling (ISEL) and expression of bcl-2 gene was assayed with immunohistochemical method. The cells stained brown were positive ones. A total of 400 cells were counted under the 400× microscope. We graded the samples according to the percentage of the positive cells: the number of positive cells ＜ 5% -; 5%-10％ +; 11％-50％ ++; ＞ 51％ ().③ Grade and quantitative data were compared with rank sum test and t-test.MAIN OUTCOME MEASURES: Effects of AMB on the rate of neu-ronal apoptosis, the activity of Mn-SOD, the concentration of MDA in mitochondria, and the intensity of the expression of bcl-2 gene.RESULTS: Totally 24 mice entered the final analysis.① Content of MnSOD was higher in young group and AMB group than in old control group (P＜0.05).② Concentration of MDA and apoptotic rate in young group and AMB group were lower than those in old control group (P ＜ 0.01).③Expression of bcl-2 gene was significantly different in young group and AMB group from that in old control group (P ＜ 0.01).CONCLUSION: AMB is found to be able to obviously inhibit neuronal apoptosis in aging mice brain by affecting the activity of Mn-SOD, the concentration of MDA and the expression of bcl-2.
