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 explore the feasibility of the ultrasonic atomization surface anesthesia with lido-caine for awake fiberoptic endotracheal intubation in patientsˊautonomous position -display before general anesthesia and to evaluate its advantages.Methods 68 adult patients who needed prone position for elective surgery under general anesthesia were selected and randomly divided into two groups,the control group and the treatment group,each group in 34 cases.In control group patients were received surface anesthesia of cricothyroid membrane puncture.In treatment group,nebulized 2% lidocaine with ultrasonic nebulizer was used for topical anesthesia.Patients lied in the prone position according to their own comfort with the guide of the medical staff in the waking state after an awake fiberoptic endotracheal intubation.The statistics of mean arterial pressure (MAP)and heart rate (HR)were recorded respectively in the basal state(T0),in the time instantly after intubations(T1 ),in the 3 minute after intubations(T2 ) and in the time instantly after the body turning(T3 ).Choking cough response were recorded during endotracheal intubation.Patients were asked the efficacy of surface anesthesia and the tolerance for awake intubation after operation.Results Patients in both two groups completed the whole process smoothly.MAP and HR had no signifi-cant differences between the two groups in the same time point (all P >0.05).There were no statistical significance between the two groups in choking cough response,the time of surface anesthesia and intubation,neither (all P >0.05).Conclusion The surface anesthesia with lidocaine by continuous ultrasonic atomizing inhalation is a good and simple method deserving generalization with plenty merits and is practicable for patients to display position autonomously. This method have the advantages of small operation,it will and can replace cricothyroid membrane puncture.

BACKGROUND: High-energy vibration is easy to damage non-cavity organs of the body and the damage effect is remarkable, but few studies concern the process of high-energy vibration-induced injury.
OBJECTIVE: To understand physiological, biochemical and pathological changes of animal bodies after high-energy vibration-induced injury.
METHODS: A total of 32 dogs were randomly divided into four groups. Dogs in the mild vibration injury group, moderate vibration injury group and severe vibration injury group received 700, 1 000, and 2 100 m/s2 vibration. Dogs in the control group were considered as normal controls. Within 14 days after vibration, serum K+, Ca2+, Zn2+, S100β, and neuron specific enolase concentrations were detected. Immunohistochemical staining was observed in the spinal cord and the brain.
RESULTS AND CONCLUSION: Serum K+, Ca2+, Zn2+concentrations showed a regular change in the three vibration injury group, and no evident change was found immediately after vibration injury. K+ concentrations reached a minimum at 0.5 day after vibration injury. Ca2+ concentrations reached a minimum at 1 day after vibration injury. Zn2+concentrations reached a minimum at 0.5 or 1 day. Above concentrations gradual y increased and became normal at 14 days. Serum neuron specific enolase and S100β expression increased at 0.5 day after vibration in the three vibration injury groups, peaked at 1 day, gradual y diminished, and recovered to a normal level or higher level at 14 days. In the three vibration groups, bleeding point of contact position and hedge position could be found in the spinal cord and brain. The degree of bleeding was more significant when kil ed instantly after vibration compared with that at 14 days. S100β, glial fibril ary acidic protein and neuron specific enolase expression increased in the spinal cord and brain.

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.
