ObjectiveTo assess a simple apparatus measuring displacement of pelvis in clinical application.MethodsTwo testers measured the displacement of pelvis of 20 healthy young subjects moving their body forward, backward, leftward and rightward in standing position. The reliability of inter- and intra-tester was tested with intraclass correlation co-efficiency (ICC). And the validity between this method and Functional Reach Test (FRT) was tested.ResultsThe ICC of inter- and intra-tester were 0.91～0.97 and 0.94～0.98 respectively, and correlated with FRT (r=0.88, P<0.01).ConclusionThis simple apparatus can be used in a balance test.

Some factors may induce accidents during physiotherapy for stroke patients. This article would summarize the general risk factors and discuss the management.

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.

Objective: To analyze the prescription dosage for discharged patients in our hospital and investigate the potential risks.Methods: A retrospective research method was adopted to statistically analyze 55 872 discharge instructions from July to September in 2015,and more attention was paid to the prescriptions with dosage over 4 weeks,expecially the ones with 26-week dosage, and the related influencing factors were studied as well.

OBJECTIVETo analyze the changes in CIE L*, a*, and b* at cervical, body, and incisal sites after tooth bleaching by using a spectrophotometer.

METHODSSixty-seven intact and healthy maxillary central incisors were in-vestigated. These incisors were darker than A3 according to the Vita Classical shade guide. The CIE tooth shade parameters L*, a*, and b* were simultaneously recorded at three tooth areas (cervical, body, and incisal) with a spectrophotometer before and after tooth bleaching (35%H2O2 coordinating with Beyond whitening accelerator irradiating). The shade dif-ferential (DeltaE) was calculated. ANOVA, paired t-test, and Pearson correlation analysis were used for data analysis.

RESULTSThe efficacy rates of tooth bleaching were satisfactory, with 86.6%, 86.6%, and 85.1% in the cervical, body, and incisal sites, respectively. The average values of DeltaE were 5.09, 4.44, and 4.40 in the cervical, body, and incisal sites. Tooth bleaching significantly increased L* and significantly decreased a* and b* in all tooth areas (P < 0.01). The decreasing range of Deltab* was more than the increasing range of DeltaL* at the cervical site; opposite results were observed at the incisal site. A positive correlation was detected between baseline b* and DeltaE.

CONCLUSIONThe spectrophotometer could objectively evaluate the whitening effect of tooth bleaching at the different tooth sites. The tooth bleaching system (35%H202 coordinating with Beyond whitening accelerator irradiating) exerts powerful bleaching actions in most of the tooth areas investigated. The order of tooth bleaching effectiveness is cervicalbody>incisal. Yellow coloration is decreased mainly at the cervical site, and brightness was increased mostly at theincisal site. The effectiveness of tooth bleaching increases as the baseline b* value increases.

Objective To study the effect of S2-protein from SARS coronavirus on the chloride channel currents in A549 cells and its possible cellular mechanisms. Methods The chloride channel currents were recorded in cultured A549 cells by using the whole-cell mode of patch clamp techniques. The experiments were divided into four groups: Control group: chloride channel currents were recorded in untreated A549 cells; S2 protein group: currents were recorded in A549 cells treated with S2 protein (final concentration 50?g/ml); calphostin C + S2 protein group: the effect of S2 protein on the currents in A549 cells pretreated with calphostin C (0.1mmol/L) for 10 minutes; SB203580+S2 protein group: the effect of S2 protein on the currents was examined with the solution containing SB203580 (20?mol/L). Results The currents of chloride channel in normal A549 cells showed outwardly rectifying properties and were insensitive to both TEA and amiloride, but were significantly inhibited both by SITS and DIDS (P
