ABSTRACT
Urea transporters (UT) play a vital role in the mechanism of urine concentration and are recognized as novel targets for the development of salt-sparing diuretics. Thus, UT inhibitors are promising for development as novel diuretics. In the present study, a novel UT inhibitor with a diarylamide scaffold was discovered by high-throughput screening. Optimization of the inhibitor led to the identification of a promising preclinical candidate,
ABSTRACT
Objective To seek an effective surgical procedure to treat patients with the varying degrees of breast ptosis and micromastia.Methods Patients were classified into Ⅰ-Ⅳ degrees based on different breast ptosis,and treated by different methods.Degree Ⅰ was treated with implanting prosthesis to the post-pectoralis major space; degree Ⅱ patients were repaired with avulsion of deeper mammary gland and pectoralis major and hanging fixed breast tissue,based on the degree Ⅰ procedure; degree Ⅲ was fixed with breast tissue flap,excised redundant epidermis by the method of double-rings and the complex of nipple and areola was shifted,based on the degree Ⅱ procedure; degree Ⅳ was repaired with implanting prosthesis and the method of lines to hanging fixed breast.Results In 116 cases of this study,there were no hematoma,infection and nipple and areola necrosis by the combined strategies.The follow-up period after the surgery was 6-31 months (mean 13.3 months).All cases had voluptuous and upright breasts,rectified breast ptosis,with the normal sense of nipple and areola.Conclusions For breast ptosis and hypoplasia,the combined strategies have better clinical therapeutic effects.
ABSTRACT
Objective To summarize the experience of the integrated treatment on mid-face ageing for better cosmetic results.Methods A total of 56 cases were treated.With using subciliary approaches,the orbicularis oculi was resected to expose the orbital septum,the orbital fat relieved and orbital septum reseted.Hyaluronic acid was injected to some patients with obvious nasolabial fold after operation.Results 56 cases were all followed up from 6 to 26 months (11.8 months on average) postoperatively.The flabby tissue had been tightened and all got better effects.Conclusions Various combination of technologies can be applied to reach the purpose of rejuvenation by correcting the volume abnormality,resetting the tissue,elevating reasonably,and filling the facial depression.
ABSTRACT
Objective To evaluate the practical efficacy of comparison method in experimental teaching of pathological anatomy.Methods The junior college students of stomatology were divided into experimental group (n =48) and control group (n =48) randomly.Students in experimental group adopted the experimental teaching with comparison method of pathological anatomy and histology while those in control group followed the traditional experimental teaching.Experiment examination results of two groups were compared and questionnaire investigation was carried out among students in experimental group.Results Average score of experiment examination in experimental group was (88.35 ±5.68) while that in control group was (78.35 ±4.86),with statistical differences (P ＜0.01).The results of questionnaire investigation showed that students in experiment group preferred comparison teaching method.Conclusions Comparison teaching method is feasible,the mechanism of which emphasizes gaining new knowledge by reviewing the old and strengthens the contact of basic subjects,therefore it is conducive to enhancing the quality of pathological experimental teaching.
ABSTRACT
Objective To measure and evaluate mesenteric artery by comparing the multi-slice spiral CT mesenteric artery images with autopsy specimens. Methods Totally 230 normal subjects were selected to undergo abdominal multi-slice spiral CT and enhanced CT. We processed the images;R3econstructed 3D images, analyzed and compare the mesenteric artery images obtained by multi-slice spiral CT with autopsy specimens. Results 1. Diameters of mesenteric artery obtained by vivo image were significantly larger than that of autopsy specimens (P<0.05);2. Start locations, branch types and running directions of both superior mesenteric artery and inferior mesenteric artery were much different between traditional autopsy specimens information and our results.3. Different reconstruction methods had different advantages. Especially, STS-MIP method could present the level of mesenteric artery better. Conclusion The method for mesenteric artery study using multi-slice spiral CT can enhance scanning and 3D reconstruction with workstation has been approved to work well, and it is superior to traditional autopsy specimen method. It is also convenient for mesenteric artery scientific evaluation. The result data of this method are reliable. Moreover, this method is available to research with large number of specimen.
ABSTRACT
Objective To investigate the clinical pathological feature and treatment of cystosarcoma phyllodesand.Methods 12 cases of cystosarcoma phyllodesand after surgical were retrospectively reviewed.Results Among the 12 cases cystosarcoma phyllodesand,5 cases underwent total mastectomy,2 cases underwent modified radical mastectomy,1 case underwent local excision and reserve nipple,and 4 cases underwent lesion removed and reserve nipple or gland.All cases were follow up between 1～18 years,1 case lost,2 cases recurred after surgical 1.5 and 2.0 years and cystosarcoma were removed again,and other patients were free from cancer cell.Conclusion The diagnosis and treatment of the cystosarcoma phyllodesand are based on the pathology.It is difficult to predict the behavior by the pure histology from the cell appearance,recurrence of the cystosarcoma phyllodesand is relevant with the different classification tumor and size.
ABSTRACT
In the pathology teaching process,teachers can help students comprehend the essential knowledge of pathology by means of dialectical thinking.The dialectical thinking method not only can make the students memorize the information better,but also can develop the correct thinking method of students and improve their capability of analyzing and solving problems.
ABSTRACT
Purpose To investigate the significance of u-PA and PAI-1 expression on the glomeruli,and the effect of heparin on their expressions in rat anti-thy1 glomerulonephritis. Methods We analyzed the cell proliferation and the expression of u-PA/PAI-1 on the glomeruli by immunohistochemistry and quantitative analysis of immunostaining. Results The cell proliferation of the glomeruli decreased significantly at 7 th,14 th,21 st day after heparin treatment in comparison to the glomerulonephritic group(P<0.05 or 0.01).The expression of u-PA and PAI-1 on the glomeruli in glomerulonephritic and heparin-treated groups was higher than that in the control group.At 3 rd,7 th,14 th,21 st day,the glomerular hypercellularity in the glomerulonephritic group was closely related to the increased expression of u-PA and PAI-1(P<0.05 or 0.01).At 3 rd,7 th day,the decreased cell proliferation of the glomeruli in heparin-treated group had close relationship with the decreased expression of PAI-1(P<0.05). Conclusions In rat anti-thy 1 glomerulonephritis model,the expression of u-PA and PAI-1 increased with glomerular hypercellularity;heparin treatment can decrease the extent of glomerular hypercellularity in rat anti-thy 1 glomerulonephritis.The treatment function of heparin might be related with the inhibitory effect of PAI-1 expression on the glomeruli.
