Objective Taken examination of patients with colon polyps by using narrow-band imaging (NBI) com-bined with magnified endoscope, to compare the difference in the opening of the gland morphology and pathological type. Methods 110 patients of colon polyps with 147 pathological histology biopsy samples collected. Using NBI combined with magnified endoscope techniques observe pit patterns and capillary patterns identify adenomatous polyps, and compared with the results of pathological histology, then analyze the adenomatous polyp diagnosis coin-cidence rate, sensitivity and specificity. Results The pit patterns of adenomatous polyps were mostly type Ⅲ, Ⅳ andⅤ. The diagnostic coincidence rate, sensitivity and specificity was 91.16%, 88.37%, 95.08%of adenomatous polyps. It was higher than ordinary colonoscopy (80.27%, 79.07%, 81.97%), and the diagnosis accuracy of intraepithelial neoplasia and early carcinoma of NBI combined with magnified endoscope was obviously higher than that by ordi-nary endoscopy examination, the differences were statistically significant. Conclusions NBI combined with magnified endoscope was superior in observing the opening of pit patterns and capillary patterns, which was helpful to diagno-sis of tumor lesions of colon polyps.

Objective:To investigate whether the likelihood of balance impairment in children with attention deficit hyperactivity disorder(ADHD) increases with the presence of disruptive behavior disorder(DBD),and whether the likelihood of co-occurring diagnosis of DBD increases in ADHD children with severer balance deficit.Methods:Three groups of 20 children each,representing pure ADHD,ADHD+DBD,and typically developing control children,were included and group matched by age and gender.Balance functions were assessed with the Balance Master in different conditions.We compared the percentages of children in each group who swayed faster than 85% of the typical control children in all conditions.Results:In the conditions of firm surface with eyes open(FI/EO) and eyes closed(FI/EC),and foam surface with eyes open(FO/EO) and eyes closed(FO/EC),the sway velocities of ADHD only group(0.65?0.26 ?/s,0.65?0.30 ?/s,0.95?0.29 ?/s,and 1.70?0.49?/s,respectively) were significantly higher than those of the typical control group(0.47?0.18 ?/s,0.43?0.19 ?/s,0.76?0.21 ?/s,and 1.27?0.38 ?/s,respectively)(P

Objective To compare the clinical effects of combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve versus spinal-epidural analgesia in total hip replacement. Methods Fifty cases of total hip replacement were randomly divided into two groups. Patients in group A received combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve,while patients in group B received spinal-epidural analgesia. Results There were no significant differences in preoperative HR, SBP,DBP and SpO2 between the groups(P > 0. 05). Compared with pre-anesthesia data,HR,SBP,DBP in group A were significantly lower during the anesthesia(P < 0. 05). In group B,there were no significant changes in HR,SBP,DBP and SpO2 during the anesthesia( P > 0. 05). Patients′ heart rate in group A showed significant changes compared with that in group B. The differences in HR,SBP and DBP between group A and B at the same time points were significant(P < 0. 05). Superior rate of anesthesia in group B is higher than that in group A(P < 0. 05). Conclusion Combined anesthesia of lumbar plexus-sciatic nerve and superior clunial nerve has limited influence on the circulatory and respiratory systems,which can be used for total hip replacement.

The primary function of optical in vivo imaging technique is tracing and detecting the action and expression of maker cells,maker microorganisms and maker molecules.This technique makes possible the noinvasive study of biological events continuously with high sensibility,simplicity and high speed.It has been applied in numerous research fields.This paper presents a review of principle and application of this technique.

ObjectiveTo detect the expression levels of macrophage migration inhibitory factor (MIF) in peripheral blood mononuclear cells (PBMCs),sera and skin tissue fluid from patients with vitiligo vulgaris,and to investigate their clinical significance.MethodsThirty-nine patients with vitiligo vulgaris and 31 age- and sex-matched normal human controls were recruited in this study.Real-time reverse transcription-PCR was employed to assess the expressions of MIF mRNA in PBMCs,enzyme-linked immunosorbent assay (ELISA) to detect the concentrations of MIF in sera and skin tissue fluid from these subjects.ResultsPatients with vitiligo vulgaris showed a significantly higher level of MIF mRNA in PBMCs (6.70 (2.64 - 8.65) vs.1.67 (1.24 - 2.45),Z=5.895,P＜ 0.05),MIF protein in sera (32.76 (10.67 - 40.98) μg/L vs.7.89 (6.13 - 9.54) μg/L,Z=5.936,P ＜ 0.05 ) and skin tissue fluid ( 167.80 ( 107.40 - 219.60) μg/L vs.42.44 (32.29 - 49.74) μg/L,Z =4.715,P ＜ 0.05) compared with the normal human controls.The expression levels of MIF mRNA in PBMCs,and MIF protein in sera and skin tissue fluid were also higher in patients with progressive vitiligo than in those with stable vitiligo (7.89 (3.89 - 9.12) vs.5.62 (2.23 - 7.29),Z=2.213,P＜ 0.05; 37.80 (29.50 - 45.70) μg/L vs.22.70 (9.36 - 37.78) μg/L,Z=2.141,P＜ 0.05; 211.50 (131.70 - 248.75) μg/L vs.144.65 (89.13 - 167.30) μg/L,Z =2.100,P ＜ 0.05).In addition,the vitiligo area severity index (VASI) score was positively correlated with the expression levels of MIF mRNA in PBMCs (r =0.486,P ＜ 0.05)and MIF protein in sera (r =0.453,P ＜ 0.05).ConclusionMIF might play a certain role in the pathogenesis of vitiligo vulgaris.

Breast cancer belongs to high morbidity malignant tumor for women. Some known aspects to breast cancer were etiological factor, pathogenesis and prescription based upon literature review of Traditional Chinese Medicine (TCM) in ancient times, and the valuable references to modern clinical medicine (CM) was offered. Some animal studies and modern clinical trials indicated that curative effect of integration of Chinese and Western Medicine in experimental group was better than that of Western Medicine treatment alone in control group. It aims to offer open-minded idea under syndrome differentiation for professional staff in clinic by arranging, inducing-and summarizing related records on breast cancer.

Objective To upgrade the satisfactory degree of foreign patients by persistently improving medical treatment quality aboard hospital ship.Methods To choose 3 days and 30 foreign cases who accepted ultramarine medical treatment on hospital ship.All the cases were Pakistani or Bangladeshi.Cases were assigned into 3 kinds of queuing program and investigated the satisfactory degree using self-made questionnaire.The program of highest satisfactory degree was used in the next 3 countries.Results Analysis showed that waiting time for preliminary diagnosis,examination and total waiting time were significantly different between program C and A; waiting time for preliminary diagnosis,examination and total waiting time were significantly different between program B and A,but time for return visit increased in program B compared to that of program A.Degree of satisfaction:70.0％～76.7％ for program A,73.3％～80.0％ for program B,96.7％～100.0％ for program C.Conclusions Program C is the best method to shorten waiting time,improve order and upgrade the satisfactory degree.This research has a significant value in the enhancement of efficiency aboard hospital ship and improvement of foreign patients' satisfactory degree.
