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.

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.

CYP2D6 genetic polymorphism results in individual difference of therapeutic effect and adverse reaction of related drugs this article made an overview for that.

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.

The chemical constituents from Euphorbia lunulata was investigated in this paper. Fourteen compounds were isolated and purified by column chromatographies on silica gel and preparative HPLC. Their structures were identified by physiochemical properties and NMR data analysis as lupeol (1), euphol (2), cassipourol(3) , 24-methylenecycloartan-3beta-ol (4), 24-hydroperoxycycloart-25-en-3beta-ol (5), 25-hydroperoxycycloart-23-en-3beta-ol (6), betulin (7), uvaol (8), (23E) -25-methoxycycloart-23-en-3beta-ol (9), (23E) -cycloart-23,25-dien-3beta-ol (10), 24-methylenecycloartan-3beta, 28-diol (11), salicinolide (12), 2alpha, 3beta, 5alpha, 9alpha, 15beta-pentaacetoxy-11,12-epoxy-7beta, 8alpha-diisobutyryloxyjatropha-6 (17) -en-14-one (13) and 3beta, 5alpha, 15beta-triacetoxy-7beta-isobutyryloxy-9alpha-nicotinoyloxyjatropha-6 (17), 11(E)-dien-14-one (14). Among them, compounds 1-11 were isolated from E. lunulata for the first time.

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 explore therapeutic effect of bisoprolol with CYP2D6 and CYP3A4 gene targeting therapy for hypertension .Methods :A total of 100 cases with essential hypertension (EH) were selected ,among them 20 ca-ses were randomly chosen to receive routine medication (bisoprolol 5 mg/d ,routine treatment group ) ,the other 80 patients were equally divided into group A (CYP2D6*10) and group B (CYP3A4*1G) .According to detection results of CYP2D6*10 and CYP3A4*1G gene polymorphism ,they were dived into group ACC (n=13) ,group ACT (n=14) ,group ATT (n=10) ,group BCC (n=21) ,group BCT (n=17) and group BTT (n=0) .Bisoprolol dosage was adjusted according to genotypes :group ACC and group BCC received 10 mg/d ,group ACT and group BCT received 5 mg/d ,group ATT and group BTT received 2.5 mg/d .Blood drug concentration ,blood pressure and heart rate were compared among above groups after two weeks .Relationship between plasma concentration of bisoprolol and gene polymorphism of drug metabolism enzyme was evaluated .Results:Comparison between related groups with same bi-soprolol dosage :there were no significant difference in blood drug concentration ,heart rate and blood pressure be-tween ACT and routine treatment group , P>0.05 all;compared with routine treatment group ,there was significant rise in blood drug concentration [ (33.5 ± 19.1) ng/ml vs .(50.13 ± 23.21) ng/ml] ,significant reduction in heart rate [ (71.4 ± 5.16) times/min vs .(66.5 ± 6.04) times/min] and blood pressure [ (127.22 ± 10.44/82.4 ± 7.27) mmHg vs .(119.48 ± 11.97/71.2 ± 10.30) mmHg] in BCT group , P<0.05 all .Conclusion:Because gene possesses polymorphism ,therapeutic effect of bisoprolol treating hypertension is differing ;the gene targeting therapy may significantly improve therapeutic effect for hypertension .
