Objective To evaluate the early change of left ventricular (LV) systolic function in patients with type 2 diabetes mellitus(T2DM) by ultrasound speckle tracking imaging. Methods Ninety-five subjects were included:40 T2DM with normal LV ejection fraction (LVEF≥50% ,group A),20 T2DM with abnormal LVEF (LVEF<550 %) (group B), and 35 normal controls. Two-dimensional strain images were acquired from LV short-axis view. LV peak systolic global and segmental radial strain and circumferential strain at the levels of mitral annulus, papillary muscle and apex, and LV systolic global and segmental rotation at the levels of mitral annulus and apex and LV peak systolic global twist were assessed. Results In group A, compared with control group, LV peak systolic radial strain parameters were not significant difference (P >0.05), peak systolic circumferential strain of part segments, average peak strain of each plane and global strain were reduced (P <50.05～0.001) ,and LV peak systolic rotation of all apical segments, peak systolic global rotation at the levels of mitral annulus and apex,and peak systolic global twist were significantly increased (P <0.05～0.001). Compared with control group and group A,all LV systolic radial strain and circumferential strain parameters, LV systolic global and segmental rotation and peak systolic global twist in group B were significantly reduced (P <0.05 ～ 0.001). Conclusions Speckle tracking imaging could be used to evaluate the early change of LV torsional deformation and LV systolic function in T2DM.

Objective To evaluate the cell-mediated immune tissue reactions of mice model of chromoblastomycosis. Methods First we developed a murine model of chromoblastomycosis subcutaneous infection with F. pedrosoi inoculated into the footpads using immunocompetent and immunocompromised mice immuned by CTX, and then by immunohistochemistry methods analyzed the expression of cytokines IL-4, IL-10, TNF-α and IFN-γ at the seventh and thirtieth day, the expression of these cytokines at the same time in the healthy mice footpads were used as control. Results In the immunocompetent mice, The expression of IL-4, IL-10 and TNF-α was significantly higher when compared with healthy control at the seventh day,showing an up-regulation pattern of Th2 and Th1 type cellular immune functions with a predominance of the Th2 response. At the 30th day, the expression of IL-10 was significantly lower when compared with the 7th day and no difference with healthy controls, while IFN-γand TNF-α were gradually increased, the T cellmediated immune drives to Th1 response from Th2. In the immunocompromised mice, the expression of IL4 and IL-10 were significantly higher, meanwhile IFN-γwas lower than those in immunocompetent or healty mice, the levels of TNF-α was not significantly different fiom healty control at the 7th day, it showed that Th2 response was more increased with the Th1 responses was significantly inhibited in the early immune reactions. At the 30th day, the Th1 type cytokines IFN-γ and TNF-α were highly significantly higher than early stage but still lower than immunocompetent levels, the level of Th2 type cytokine IL-10 rradually decreased although it was still above the other two rroups. Conclusion In different immune state, there was an immune defence translation from the predominance of Th2 type cellular immunity to Th1 type in the process of murine model of chromoblastomycosis. Thl type cytokines which favors resistance to fungal disease, played a major role at controlling the development of chromoblastomycosis.

· AIM: To investigate whether heat shock protein 27 (HSP27) is induced in retinal ganglion cells (RGCs) in experimental rat glaucoma and whether the induction of HSP27 by intraocular pressure (IOP) elevation can increase serum autoantibody to HSP27 in the model.IOP elevation、Sham and normal groups by SPSS12.0. IOP was raised by electrocoagulating at least 3 episcleral veins and limbal veins on the right eye of each rat in IOP elevation group and its contralateral eye was used as controls. Immunohistochemical staining for HSP27 was performed in RGCs and retinal nerve fiber layer (RNFL) and serum immunoreactivity against HSP27 was detected by means of enzyme-linked immunosorbent assay (ELISA) in three groups.RNFL of the eyes with IOP elevation, while it was expressed weakly in untreated control eyes. Compared with sham and normal groups, serum autoantibody to HSP27 was slightly high at 1wk (P ＞0.05) and significantly increased at 2, 3, 4 and 8wk (P＜0.05) in IOP elevation group.enhanced expression of the endogenous HSP27 might play an important role in glaucomatous optic neuropathy.

AIM: To study the experimental method of inducing the chronic intraocular hypertension in rat eyes.METHODS: Twenty Wistar rats were randomly divided into ocular hypertension and Sham control groups. Intraocular pressure (IOP) was raised by electrocoagulating at least 3 episcleral and limbal veins on the right eye of each rat in ocular hypertension group and its contralateral eye was used as control. At 1, 2, 3, 4 and 8wk after the electrocoagulation of the veins, IOP were measured. RESULTS: The treatment of electrocoagulation caused a significant IOP increase of the right eyes over the baseline, over the contralateral eyes, and over the sham control eyes (repeated measures ANOVA, P＜0.001). At 1wk,IOP was (30.12± 5.L8 ) mmHg (1kPa=7.5mmHg), and maintained the high IOP up to 8wk.CONCLUSION: The chronic intraocular hypertension model could be successfully created by electrocoagulating three or more episcleral and limbal veins.

Objective To explore the value of wave intensity (WI) parameters in evaluating hemodynamic changes of cardiovascular system before and after 131I therapy in hyperthyroid patients.Methods Forty-seven hyperthyroid patients were enrolled as hyperthyroid group,while 47 healthy volunteers were considered as control group.Both of the hyperthyroid and control group took WI examinations,and WI curves of their right common carotid arteries were recorded.WI parameters of WI curve were automatically measured as followed:value of the first positive peak (W1),value of the second positive peak (W2),area of the negative peak (NA),and the square root of NA (A).Twenty-five patients of the hyperthyroid group received 131I therapy were enrolled as treatment group.All these patients were followed up for 3 months.The repeatability of the WI parameters was evaluated in 10 hyperthyroid patients and 10 normal volunteers selected at random from the investigation.Results W1,W2,A in hyperthyroid group increased compared with those in control group,and independent-samples t test showed very significant difference (P=0.000,P=0.000,P=0.000).W1,A decreased after 131I therapy compared with those before treatment,and paired-samples t test showed significant difference (W1:P=0.001;A:P=0.011).A in hyperthyroid group had positive correlation with FT3 (r=0.508,P=0.003);W1 after 131I therapy in treatment group had positive correlation with FT3 and FT4 (r=0.601,P=0.002;r=0.680,P=0.00);W2 after 131I therapy in treatment group had positive correlation with FT3 and FT4 (r=0.549,P=0.005;r=0.570,P=0.004).The repeatability of W1,W2,NA and A were good by consecutive measurement of identical observer.Conclusions WI peak parameters of hyperthyroid patients were higher than those of healthy volunteers,and some sensitive parameters were decreased after 131I therapy,which may provide the basis for assessing the effectiveness of 131I therapy.

Objective To assess right ventricular(RV)regional systolic function in patients with tetralogy of Fallot(TOF)by ultrasound speckle tracking imaging(STI).Methods Longitudinal peak systolic velocity(V), strain(ε),strain rate(SRs)were measured in RV free wall and interventricular septum(IVS)for basal, mid and apical segment in 38 patients with TOF and 35 healthy controls by STI from the apical 4-chamber view and compared between groups.Results Compared with controls,ε and SRs of RV free wall and IVS for all segments were significantly impaired in patients with TOF(P<0.05 for all).Whereas, V of RV each segment were normal (P>0.05 for all).In patients with TOF and controls.V,εand SRs of RV free walI for all segments were higher than those of IVS except SRs of RV apical segment.Conclusions RV systolic function in patients with TOF was decreased, RV longitudinal systolic function is accurately and objectively studied by STI.

Objective To analyze the left ventricular(LV) rotation and twist by two-dimensional ultrasound speckle-tracking imaging(STI),and evaluate the correlation between twist and other components of LV contraction in uremia patients. Methods Twenty-nine uremia patients and twenty-nine healthy volunteers were included. High frame rate two-dimensional images were recorded from the left ventricular short-axis views both of the basal and apical planes. Segmental and global LV rotation were recorded at both The peak systolic LV twist was significantly decreased in uremia patients(P <0. 001). The loss of LV twist occurred mainly by the impairment of maximal global counterclockwise apical rotation(P <0. 001),and was augmented by somewhat less reduction in global clockwise basal rotation although the differences was not significantly reduced(P<0.01), while only the posterior and inferior of the basal plane was significantly fraction(r=0.645,P=0.000), LV end-diastolic volume (r=-0.549,P=0.002), LV end-systolic volume(r=-0.673, P = 0.000) in uremia patients. Conclusions STI enables quantification of segmental and global LV rotation in an objective manner in uremia patients,and provides a new method for evaluation of segmental and global LV systolic function.
