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.

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 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.

Objective To study the expression of endothelin 1 (ET 1) mRNA in keratinocytes in patients with vitiligo. Methods Fourteen patients with progressive vitiligo were measured by hybridization in situ. Results Our results showed that the expression of ET 1 mRNA was markedly decreased. Conclusion The results revealed that decreased ET 1 expression may be associated with the pathogenesis of vitiligo. The cause and role of decreasing of ET 1 expression of keratinocyte in vitiligo lesion need to be studied further.

Objective To investigate the clinical efficacy and safety of combined acupuncture and medicine in treating polycystic ovarian syndrome infertility.Methods Ninety patients with polycystic ovarian syndrome infertility were randomly allocated to treatment and control groups, 45 cases each. The control group received oral administration of clomifene citrate tablets plus muscular injection of chorionic gonadotropin and the treatment group, electroacupuncture in addition. The ovulation rates, pregnancy rates, incidences of ovarian hyperstimulation syndrome (OHSS), ectopic pregnancy rates and early miscarriage rates were compared between the two groups of patients. Results The ovulation rate and the pregnancy rate were 97.8 % and 37.8%, respectively, in the treatment group and 75.6% and 17.8%, respectively, in the control group; there was a statistically significant difference between the two groups (P<0.05). Of 17 pregnant patients in the treatment group, 2 had early miscarriage, accounting for 11.8% and none had ectopic pregnancy, accounting for 0.0%. Of 8 pregnant patients in the control group, 4 had early miscarriage, accounting for 50.0% and none had ectopic pregnancy, accounting for 0.0%. The incidence of OHSS was 4.4% in the treatment group and 6.7% in the control group; there was no statistically significant difference between the two groups (P>0.05).Conclusions Combined use of acupuncture and medicine can increase the ovulation rate and the pregnancy rate in patients with polycystic ovarian syndrome infertility. It does not significantly cause ovarian hyperstimulation and ectopic pregnancy and may decrease the early miscarriage rate.

OBJECTIVE To investigate the distribution of nosocomial infection(NI) in patients after surgical procedures and antimicrobial resistant change of pathogens. METHODS A total of 195 strains of pathogenic bacteria isolated from the samples after surgical procedures from Jan 2006 to Dec 2006 were analyzed by WalkAway-40 system with NC31 system. RESULTS Among the 195 strains of pathogenic bacteria,there were Gram-negative bacilli(74.4%) and Gram-positive cocci(25.6%).The dominating microorganisms were Escherichia coli,Klebsiella pneumoniae,Pseudomonas aeruginosa and Staphylococcus aureus.The result showed that vancomycin and imipenem still had better activities to the bacteria. CONCLUSIONS Surgical incision infection should be monitored by some effective measures,and it is very important to prevent surgical infection and use antibiotics reasonably.
