Objective To evaluate the functions of the left atrium using two-dimensional strain(2DS)echocardiography and left atrium volume index(LAVI)in the patients with hypertrophic cardiomyopathy(HCM)and explore its clinical value.Methods There were 37 patients with HCM and 35 healthy subjects enrolled in our study.Left atrial passive ejection fraction(LAPEF)and left atrial active ejection fraction(LAAEF)were calculated using Simpson's method.The analysis for atrial longitudinal peak systolic strain(S),peak systolic stain rate(SRs),peak early diastolic stain rate(SRe)and peak late diastolic strain rate(SRa)on the interatrial septum and the lateral wall of the left atrium were performed using 2DS echocardiography.Results LAPEF and LAAEF significantly decreased compared with those in the control group(P 0.05,P 0.01).LAVI in HCM group increased compared with that of the control group(P 0.01).S,SRs,SRe and SRa of the interatrial septum and the lateral wall were lower in patients with HCM than those in control group(P 0.05).LAVI was negatively correlated to 2DS(r =0.73,P 0.05).Conclusion The left atrial functions decreased in patients with HCM.2DS and LAVI are readily obtained parameters that provide unique data about global and segmental atrial functions.

Objective To investigate the clinical significance of homocysteine(Hcy) and glycated hemoglobin (HbA1c) in patients with diabetic retinopathy.Methods From March 2013 to February 2015,a total of 168 patients with diabetes from Beijing Jishuitern Hospital were divided into diabetic retinopathy group (76 cases,32 male,44 female,average age 62.97 ± 12.46) and non-diabetic retinopathy group (92 cases,46male,46 female,average age 58.14 ± 13.71),and 65 cases of healthy subjects (46male,46 female,average age 60.24 ± 10.85) were enrolled as normal control group as well.Hcy and HbA1c were detected in all groups.Multiple independent samples nonparametric tests were used to compare the difference between groups.The concentrations of Hcy and HbA1c between DR group and NDR group were analysised by ROC curve analysis.Result The Hcy levels in normal control group,NDR group and DR group were 7.00 (4.55-10.50) μmol/L,12.45 (10.30-15.10) μmol/L,20.10 (16.63-25.68) μmol/L respectively.The HbA1c levels in normal control group,NDR group and DR group were 5.30 (5.00-5.70) %,6.80 (5.83-8.03) %,7.25 (6.50-8.60) % respectively.There was no significant difference in Hay and HbA1c levels between groups (P < 0.01);Compared with non-diabetic retinopathy group,levels of Hcy,HbA1c in diabetic retinopathy group were obviously higher;The optimal diagnostic cut-off values of Hcy was 14.35 μmol/L,at this cut-off value,the sensitivity was 96.05%,specificity was 68.48%;The optimal diagnostic cut-off values of HbA1c was 6.05%,at this cut-off value,the sensitivity was 98.68%,specificity was31.25%.Conclusion Patients with Diabetic retinopathy might have hyperhomocystinemia,and detection of Hcy may contribute to the early diagnosis of diabetic retinopathy.

As a new type of carbon nanomaterials, fluorescent carbon dots (fluorescent CDs) have many advantages when compared with the traditional fluorescent probes. They are photoluminescence stable and resistance to photo bleaching. Moreover, they are excellent in biocompatibility, low-toxic and easy to modify. All these above make them a promising optical image material as a probe in optical image. This article reviews structure, the common carbon sources, the preparation methods, and the light-emitting principles of the carbon dots. We also introduce the research progress of fluorescent carbon dots in biomedicine, and the problems need to be resolved in the study of fluorescent CDs.

Anti-glutamic acid decarboxylase antibody-associated encephalitis is a kind of autoimmune encephalitis mediated by anti-glutamic acid decarboxylase antibody, which belongs to anti-neuronal intracellular synaptic protein antibody-associated encephalitis. Clinical manifestations include stiff-person syndrome, cerebellar ataxia, limbic encephalitis, seizures, etc., often associated with a variety of autoimmune diseases, rarely associated with tumors. Detection of anti-glutamic acid decarboxylase antibody is crucial for clinical diagnosis. Immunotherapy helps to relieve symptoms and improve prognosis. The incidence of this disease is low, and there are few reports at home and abroad. This paper intends to review the research on this encephalitis, hoping to improve the clinicians′ understanding and the level of diagnosis and treatment of the disease.

Objective To investigate the effects of liraglutide on the proliferation and differentiation of mouse pre-osteoblasts MC3T3-E1 exposed to higher glucose concentration. Methods MC3T3-E1 cells were cultured and divided into control group and liraglutide group. In liraglutide group, cells were treated with different liraglutide concentrations (10-9 mol/L, 10-8 mol/L, and 10-7 mol/L, respectively) for 48 hours. Cell proliferation was tested with CCK-8. The mRNA expressions of typeⅠcollagen (COL-Ⅰ), osteopontin (OPN), and alkaline phosphase ( ALP) were detected using semi-quantitative RT-PCR. Results ( 1 ) Compared to control group, the proliferation rate of different liraglutide concentration groups (10-9 mol/L, 10-8 mol/L, and 10-7 mol/L) increased significantly (all P<0. 05), the proliferation rate was the highest in 10-8mol/L liraglutide group. (2)The expression of COL-Ⅰ, OPN, and ALP mRNA in liraglutide groups were higher than those in control group (all P<0. 05). The optimal concentration of liraglutide was 10-8 mol/L. Conclusion Liraglutide within a certain concentration range may improve the proliferation and differentiation of mouse pre-osteoblasts MC3T3-E1.

Objective: To study the relationship between CYP2D6*10 gene polymorphism and metoprolol therapeutic effect for hypertension. Methods: A total of 60 patients with essential hypertension (EH) received metoprolol 47.5mg/d for 3d. After 3d the plasma metoprolol concentration after oral 2h was measured. Polymorphism of CYP2D6*10 gene was detected by PCR-RFLP. According to results of gene detection, the patients were divided into CC genotype group (wild type homozygote, fast metabolism type, n=14), CT genotype group (heterozygous mutation, intermediate metabolism type, n=25) and TT genotype group (homozygous mutation, slow metabolism, n=19). Metoprolol dosage was adjusted according to CYP2D6*10 genotype. After one week, plasma concentration of metoprolol after oral 2h was measured again, and mean heart rate and blood pressure were measured before and after gene-directed therapy. Results: Before gene-directed therapy, compared with CC and CT group there was significant increase in plasma concentration of metoprolol [(26.57±19.40) ng/ml vs. (23.88±12.86) ng/ml vs. (64.74±32.94) ng/ml, P<0.01] in TT group; compared with TT group, there were significant rise in mean systolic blood pressure [mSBP, (132.84±13.40) mmHg vs. (144.14±14.28) mmHg], mean diastolic blood pressure [mDBP, (76.95±9.07) mmHg vs. (81.36±7.33) mmHg] and mean heart rate [mHR, (69.13±11.83) times/min vs. (76.66±7.33) times/min] in CC group, P<0.05 all. After gene-directed therapy, there were no significant difference in plasma concentration of metoprolol, mSBP, mDBP and mHR among all groups, P>0.05 all; Compared with before gene-directed therapy, there was significant increase in plasma concentration of metoprolol, and significant decrease in mSBP, mDBP and mHR in CC group (P<0.05). There were no significant difference in blood pressure and heart rate between before and after treatment in CT group and TT group (P>0.05). Conclusion: CYP2D6*10 gene polymorphism affects metoprolol metabolism and its therapeutic effect on hypertension, gene-directed therapy can significantly improve drug therapeutic effect and reach ideal therapeutic goal in short time.
