AlM:To observe and compare the influence of different incision cataract phacoemulsification on comprehensive state in patients. METHODS: Sixty patients with cataract who were treated with phacoemulsification in our hospital from November 2012 to May 2014 were selected as research object, and they were divided into group A ( corneal incision group) 30 cases and group B ( corneoscleral rim incision group) 30 cases according to the disease state. Epithelial and incision repair time, tear break-up time, tear secretion, corneal staining score and tear related indexes before and after the treatment of two groups were respectively analyzed and compared. RESULTS: The epithelial and incision repair time constitution of group B were better than those of group A, the incision repair time, tear break - up time, tear secretion, corneal staining score and tear related indexes at 1,7, 14 and 28d after the treatment were all significantly better than those of group A too, there were all significant differences (all P<0. 05).CONCLUSlON: The application value of corneoscleral rim incision in the patients with cataract phacoemulsification is relatively higher,and bad influence of this method for the patients is smaller, the postoperative recovery of comprehensive state are faster.

Objective To explore the feasibility and operation methods of interforniceal diaterma keyhole approach for operative therapy of apex basilar artery aneurysm. Methods Interforniceal diaterma keyhole approach was designed to interpeduncular cistern with diaterma incision from tuber cinereum to posterior perforated substance and between bilateral mammillary bodies. The simulation operations of interforniceal diaterma keyhole approach were performed in 16 cadaveric heads by assisting with Stryker neuronavigation. Anatomic structures were observed by surgical microscope and measured by Stryker neuronavigation in the keyhole approach operations. Results The operations of interforniceal diaterma keyhole approach could be accomplished successfully in 16 cadaveric heads. The distances from bregma to superior margin of interventricular foramen, superior margin of adhaesio interthalamica, mammillary body, superior margin of aqueduct of midbrain and bifurcation of basilar artery were (68.4±4.6)mm, (66.3±6.0)mm,(86.3±5.3)mm, (82.0±7.6)mm and (91.8±5.0)mm respectively. The length of surgical window of diaterma was (9.5±2.6)mm from tuber cinereum to posterior perforated substance between bilateral mamillary bodies. The apex of basilar artery, P1 and P2 of posterior cerebral artery, superior cerebellar artery, posterior communicating artery and perforating branches from them could be exposed distinctly in interpeduncular cistern. The scope of operative exposure region was front to clivus and dorsum sellae by dissected the Liliequist panniculus, lateral to oculomotor nerve and posterior to interpeduncular fossa. The bifurcation of basilar artery apex was deviation to left in 68.8%. The bilateral posterior cerebral arteries were oblique to the anterolateral in 68.8%. There were 1-4 perforating branches from the apex of basilar artery in the included angle of bilateral posterior cerebral arteries.

ObjectiveTo investigate the value of high-frequency ultrasound in assessment of the therapeutic efifcacy of traditional Chinese medicine in patients with breast dysplasia using.MethodsFrom March to September in 2014, 50 patients with breast dysplasia in the Third Affiliated Hospital of Beijing University of Chinese Medicine were enrolled in the study. In addition, they were treated with Xiaozheng pills. Before and after treatment, these patients were examined using ultrasound. The thickness of the breast gland layer in each patient was measured. When the dilated ducts lactiferous, cysts, hypoechoic areas, or nodules of the breast were detected, the diameter or volume was measured or calculated. A grading system of the breast dysplasia was used to evaluate the disease degree, and the quadrants of the breast dysplasia were counted. The thickness of the breast gland layer, the volume of cysts and nodules, the diameter of hypoechoic areas and the dilated ducts lactiferous, the number of the breast dysplasia were compared with the pairedt-test. The grading of the breast dysplasia was compared with rank sum test.ResultsThere were significant decreases in the thickness of the grand layer, the diameters of the ducts lactiferous and the hypoechoic area after treatments [(15.92±4.73) mm vs(13.02±4.20) mm,t=2.240,P<0.01; (2.26±0.58) mm vs (1.71±0.47) mm,t=5.202,P<0.01; (21.14±5.57) mm vs(17.80±4.63) mm,t=5.529,P<0.01]. However, there were no significant differences in the volume of cysts and nodules. The grading of the breast dysplasia showed statistical difference (z=-5.667,P<0.01), and the number of the breast dysplasia quadrants was reduced markedly (5.38±1.85 vs3.28±1.97,t=7.566,P<0.01).ConclusionsUltrasound can be an effective method in assessment of patients with breast dysplasia treated with the traditional Chinese medicine. The assessment can be based on some signs, including the thickness of the grand layer, the diameters of the ducts lactiferous, and the diameters of the hypoechoic area. The grading system and breast quadrants counting in these patients may be added as supplementary criteria to make a complete therapeutic evaluation.
