Objective To explore the effect of the contrast frame mirror and the corneal contact lens correction on the optical properties of the human eye.Methods120 cases of myopia patients from 2014 September to September 2015 in our hospital for vision correction were randomly divided into two groups: control group, observation group wearing frame mirror, wearing contact lens, the optical properties of the eye were compared between the two groups.ResultsThe corrected visual acuity of observation group hadno significant difference compared with the control group;no significant difference in the values of refractive foveal contrast;foveal refractive value contrast in the two groups had no statistical difference;the observation group T30 degrees for peripheral refraction was (1.00±0.21) D, N30°peripheralrefraction was (0.34±0.08) D,were significantly lower than the control group (P<0.05).The good rate of observation group was significantly higher than the control group, the incidence of corneal complications was significantly lower than that of the control group (P<0.05).ConclusionThe frame and the corneal contact lens can be well corrected visual acuity, the corneal contact lens for the correction of certain peripheral hyperopic defocus has advantages, can effectively reduce the peripheral hyperopic defocus, delaying myopia, and improve the comfort and safety.

Objective To investigate the role of Ro52 antigen fragment from amino acid (AA) 119 to 264 that contains leucine zipper motif in forming the epitopes of Ro52 autoantigen. Methods cDNA encoding Ro52 antigen fragment from aa 119 to 264 was amplified by PCR from human heart cDNA first strand. The obtained cDNA fragment was inserted into vector pMTY4 and transformed into E. coli pop2136 for fusion protein expression. The recombinant fusion protein was then purified, and the antigenicity was determined by immunoblotting. Results A 28 000 Dalton fusion protein was obtained. It was highly expressed in host E. coli pop2136. 61.90% of the anti-full-length Ro52 positive sera reacted with the fusion protein in immunoblotting. Conclusion The results suggest that the antigen fragment from the 119 AA to 264 AA that contains the leucine zipper motif represents an important epitope region in Ro52 autoantigen.

Objective To detect the possible epitopes of 52 000 dalton Ro/SSA autoantigen and selectively clone the antigen fragment containing the leucine zipper motif. Methods The structure of 52 000 dalton Ro/SSA autoantigen was analyzed by protein structure analysis system. The cDNA encoding the antigen fragments from amino acid (aa) 119 to 264 was amplified from cDNA first strands of human heart by polymerase chain reaction (PCR). The PCR product was inserted into the vector pMTY4, and transfected E. coli pop 2136 for fusion protein production. Results Computer analysis showed that the 52 000 dalton Ro/SSA antigen had alpha helixes in its structure, and had good antigenicity, moderate flexibility and poor surface probability. The PCR product was 440bp in length. The recombinant fusion protein was 28 000 dalton. DNA sequencing proved the accuracy of the research. Conclusion The 52 000 dalton Ro/SSA autoantigen has good antigenicity. The cloning of the antigen fragment will help to elucidate the possible role of leucine zipper motif in forming the epitope of the antigen.

Objective To investigate the association between nonalcoholic fatty liver disease (NAFLD) and metabolism or carotid intima-media thickness (CIMT) in Type 2 diabetic(T2DM). Methods According to the liver B-ultrasonography, a total of 321 T2DM patients were divided into two groups, with or without NAFLD. Metabolic indexes such as BMI, BP, blood glucose, blood lipid, uric acid ( UA ), insulin, C-peptipe,insulin resistance index(HOMA-IR) between the two groups were compared, and the relationships between alanine aminotransferase (ALT) and the above indexes were analyzed. Furthermore,the CIMT of the two groups were compared, and the relationships between NAFLD, ALT and CIMT were investigated by correlation and regression analysis. Results Compared with the group without NAFLD, the patients with NAFLD had higher level of BMI, triglyceride ( TG ), UA, fasting blood glucose ( FBG ), fasting insulin ( FIns ), fasting C peptide (FCP) ,HOMA-IR,and lower level of high density lipoprotein ( HDL-C ) significantly; BMI ( OR = 1.25, P ＜0. 001 ), TG ( OR = 1.74, P = 0. 008 ) and HOMA-IR ( OR = 2. 33, P = 0.010) were independent risk factors of NAFLD while H DL-C was independent protective factor; ALT was positively correlated with BMI (r = 0. 255, P ＜0. 001 ) ,TG(r =0. 156,P ＜0. 018) ,UA(r =0. 239,P ＜0. 001 ) ,FIns(r =0. 213,P =0. 001) ,FCP(r =0. 199,P ＜0. 003), HOMA-IR ( r = 0. 247, P ＜ 0. 001 ) and negatively correlated with HDL-C ( r = - 0. 199, P =0. 002) ,and BMI (β =0. 456,P =0. 048) ,UA (β =0. 021 ,P =0. 025) and HOMA-IR(β =3.634 ,P =0. 004)were independent associated facrors. The difference of CIMT between the two groups didn't reach statistical significance, while mutiple regression analysis revealed that ALT was independently associated with CIMT(β =0. 002,P = 0. 013). Conclusion T2DM patients with NAFLD show more serious disorder of metabolism and insulin resistance. ALT is an independent risk factor of CIMT in T2DM patients.

Objective To evaluate the diagnostic value of high frequency echocardiography on mice with doxorubicin-induced cardiotoxicity and find out the most valuable monitoring indexes for early doxorubicin-induced myocardial damage.Methods Forty mice were divided into doxorubicin-injection group (ADM group) and control group randomly.Twenty mice in each group were injected with doxorubicin and saline at the same dose for 5 weeks continuously.The parameters of cardic function of ADM group and contol group were observed by high-frequency echocardiography after infection.Brain natriuretic peptide (BNP) tested by euzymelinked immunosorbent assay(ELISA) and pathological findings were used as the golden standard.Results ①The left ventricular long axis view and the apical four chamber view could be displayed clearly by transthoracic high-frequency echocardiography.②After 5 weeks intervention,weight,heart rate,left ventricular ejection fraction (LVEF),left ventricular fractional shortening (LVFS),E/A,E wave deceleration time(EDT) and other parameters showed marked difference between ADM group and control group(P ＜0.05).③The decrease of diastolic function was earlier than systolic function in ADM group.④LVEF and E/A presented good negative linear correlation to BNP(r =-0.622,P ＜0.05; r =-0.593,P ＜0.01).EDT showed positive linear correlation to BNP(r =0.501,P ＜0.05).Conclusions Cardic function of mice with doxorubicin-induced myocardial damage could be early evaluated accurately by high-frequency echocardiography,which contained good relativity with BNP.
