2.Application of spatio-temporal image in normal fetal heart ultrasonography
Chinese Journal of Medical Imaging Technology 2009;25(10):1841-1844
Objective To explore the basic method and clinical application of spatio-temporal image correlation (STIC) in the routine scanning of normal fetal heart. Methods Totally 120 volume datasets of normal fetal heart were acquired with 2D and STIC, respectively. The difference in time between the two methods were compared and the basic imaging method was explored and analyzed.Results Satisfactory gray-scale volume acquisitions were accomplished in all 120 cases. The quality of the images derived from volume datasets were comparable to that directly obtained from 2D echocardiography. No significant difference of visualization rate was found between the two methods (P>0.05). Some views that could not be showed with 2D were acquired with STIC. In fetal heart screening, STIC (n=104) and routine ultrasonography (n=85) took (4.47±2.32) min and (5.26±2.01) min per case, respectively.Conclusion STIC provides more views and information than 2D, simplifies the picture-gathering process, decreases the dependence of examiner, increases the efficiency, and decreases the exposure upon fetal heart obviously.

Objective To analyze strain characteristics of hypertrophic cardiomyopathy(HCM) and explore the clinical value of strain rate imaging in differentiating HCM from hypertensive left ventricular hypertrophy(H-LVH). Methods Parameters of strain and strain rate were obtained and compared among 23 HCM patients, 30 patients with H-LVH and 20 healthy people(control group). Results In HCM group, systolic strain(?_ sys ),peak systolic strain rate(SR_ sys ), early diastolic strain rate(SR_ dia ) obtained from inter-ventricle septum(IVS) were smaller than that obtained from left ventricle posterior wall(LVPW), while SR_a increased in IVS. ?_ sys ,SR_ sys ,SR_ dia in both patients with HCM and H-LVH were smaller than that in control group, while atrial systolic strain rate(SR_a) increased in HCM group and H-LVH group. ?_ sys , SR_ sys , SR_ dia , SR_a obtained from IVS and ?_ sys , SR_ dia obtained from LVPW in HCM group showed statistic differences compared with H-LVH group. Conclusions Strain rate imaging could accurately detect the abnormal regional myocardial function of HCM and can be applied as a useful tool in discriminating HCM from H-LVH.

The patient is an 11-year old boy, who was born with universe alopecia as well as dry and coarse skin. When he was 3 months old, photophobia was noticed, and since then, upper respiratory tract infection had occurred twice a month complicated by frequent diarrhea. He had short stature with slight conjunc- rival congestion, corneal vascularization, opacity, coarseness and poor vision. No abnormality was found in the teeth, sweating ability, or hearing. He had universal alopecia; his skin was dry and rough with generalized rhombus- or polygon-shaped scaly patches. Particularly thick brown scales were observed on the upper limbs. Moreover, there were spiny follicular papules on the abdomen and axillae, hyperkeratosis of palm and sole, and dystrophic nails. Hyperextensibility of proximal interphalangeal joints of the third, fourth and fifth fingers was noticed. He also suffered from mental retardation, the verbal intelligence quotient being 52, performance intelligence quotient lower than 40, full intelligence quotient lower than 40, but no abnormality was found in the heart, lung, liver or spleen. Histopathology of skin on the abdomen suggested a change characteristic of ichthyosis. Chromosome analysis revealed a karyotype of 46, XY. This is the first diagnosed case of ichthyosis follicularis with atrichia and photophobia syndrome in China.

Objective To study the influence of transferring a dominant-negative Stat3 gene, Stat3?on colon cancer cells' proliferation and apoptosis in vitro. Methods Cell culture of human colon cancer cell line SW480 and transient transfection were used to evaluate the effect of transferring Stat3?to cancer cells. Cell proliferation, cell cycle and apoptosis were quantified by MTT and flow cytometry, respectively. The mRNA expression of Stat3's target gene cyclin D1 and bcl-xL was detected by reverse transcription polymerase chain reaction. Independent t tests were used for data statistics. Results 36 h after Stat3?plasmids transfection, proliferation of SW480 cells was significantly inhibited (t =5. 216,P = 0.006); cell proportion of G0/G1 phase increased from 40.37% to 67.25% and early apoptosis cells increased from 5. 34% to 24. 42% ; mRNA expression of cyclin Dl and bcl-xL declined significantly (t = 5.288,P=0.010;t=3.517,P=0.025). Conclusion Blocking Stat3 signaling pathway by transfection of Stat3?plasmid inhibits the proliferation and promotes apoptosis of colon cancer cells, which provides a experimental foundation of Stat3 targeted colon cancer gene therapy.
