Evalation of Jingzhi Xiaoban Tablet in Improving Heart Function of Coronary Heart Disease Pa- tients by Doppler Tissue Imaging and Speckle Tracking Imaging Technology / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To evaluate the role of Jiangzhi Xiaoban Tablet (JXT) in improving heartfunction of coronary heart disease (CHD) patients by tissue Doppler imaging (TDI) and speckle trackingimaging (STI) technology.</p><p><b>METHODS</b>Recruited were 60 inpatients with confirmed CHD by coronary angiography at First Affiliated Hospital, Hunan University of Traditional Chinese Medicine from October 2013to November 2014. They were assigned to the treatment group (group A) and the control group (groupB) according to random digit table, 30 cases in each group. Patients in group A took JXT, 0.45 g/tablet,4 tablets each time, 3 times per day, while those in group B took Simvastatin Tablet, 20 mg/tablet, 1 tablet each time, once per evening. The therapeutic course for all was 8 weeks. The long axis view of theheart of 18 segments STI Peak strain LS and TDI peak systolic Sa parameters were performed in all patients before and after treatment.</p><p><b>RESULTS</b>Before treatment segments of STI strain LS and TDI longitudinal peak systolic peak Sa were not statistically different between the two groups (P > 0.05). Each segment of STI peak longitudinal strain LS and TDI peak systolic Sa in the two groups were higher after treatment than before treatment (P < 0.05). After treatment each segment of STI parameters of LS and eachTDI segment parameters of Sa were significantly lower in group B than in group A (P < 0.01).</p><p><b>CONCLUSION</b>JXT could improve heart function of CHD patients to different degrees, and its curative effect was betterthan that of routine Western medicine (Simvastatin Tablets) treatment.</p>

Reaction of epithelial cell rests of malassez to tooth emergence and occlusal function reaction of epithelial cell rests of Malassez to tooth emergence and occlusal function / 华西口腔医学杂志

<p><b>UNLABELLED</b>OBJECTIVE To observe the morphology and proliferation of epithelial cell rests of Malassez (ECRM) during tooth emergence and occlusal function, and to evaluate its roles.</p><p><b>METHODS</b>Cytokeratin 14 (CK14) was applied as special marker of ECRM cells. The morphology and distribution of ECRM were examined by light and transmission electron microscopy. PV two-step immunohistochemical method was used to detect the expression of CK14 and proliferating cell nuclear antigen (PCNA) in ECRM.</p><p><b>RESULTS</b>ECRM experienced instinct morphological changes during tooth emergence and occlusal function. They were observed as network of epithelial cells labeled by CK14, especially in furcation level regions of mouse molars and active cell proliferation during occlusion found period. Cell apoptosis was observed in many ECRM by transmission electron microscopy during late stage of the progess.</p><p><b>CONCLUSION</b>ECRM may not only an accidental left-over of early embryonic development but rather play significant roles in occlusion found period.</p>
