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.

AIM: To investigate the effect of peroxisome proliferator-activated receptor ? (PPAR?) activator rosiglitazone on myocardial ischemic-reperfusion injury in rats. METHODS: Forty-two SD rats were randomly divided into three groups: sham group (n=14), I/R group (n=14) and I/R+rosiglitazone group (n=14). Myocardial infarct size was assessed by NBT staining. Plasma and myocardial angiotensin and aldosterone as well as plasma renin activity were detected by radioimmunoassay. RESULTS: Compared with I/R group, myocardial infarct size was reduced by 23.9% (P

Background Cardiomyocytes apoptosis was related to oxidative stress which has been shown to play an important role in ventricular remodeling after myocardial infarction(MI).Probucol is a hypolipidemic and antioxidant agents.Several reports demonstrated its cardioprotective effect after MI.However,the exact effect of probucol on the modification of the apoptosis related gene Bcl-2 and Bax is not clear.Objective To investigate the effects of probucol on mRNA and protein expression of Bcl-2,Bax and oxidative stress in myocardial infarcted rats.Methods Forty-one SD rats that survived 24 h after ligating left anterior descending coronary artery were randomly to receive placebo-saline(5 mL/d,n=20)or probucol(probucol 60 mg/kg?d,n=21).Twelve rats underwent sham operation were served as control(n=12).Six weeks after treatment,hemodynamic pararmeters and left ventricular function were measured with catheterization.Cardiomyocytes apoptosis were determined by TUNEL method.Myocardium mRNA of Bcl-2 and Bax expression levels in the non-infarcted myocardium were as- sessed by RT-PCR.The myocardium protein expression of Bcl-2 and Bax in the non-infarcted myocardium were de- termined by Western blot.Colorimetry was used to determine oxidative metabolism index in myocardium.Results 1)Compared with the sham rats,all MI rats showed marked decrease in Bcl-2 mRNA and protein expression in myo- cardium with increase of Bax mRNA and protein expression and apoptosis index(P

OBJECTIVETo observe the efficacy of acupuncture on pain after replantation of severed finger.

METHODSA total of 80 patients who underwent replantation of severed finger were randomly divided into an observation group and a control group, 40 cases in each one. The patients in the control group were treated with postoperative routine care of hand surgery, while patients in the observation group, based on the regular treatment, were treated with acupuncture within first 72 h of surgery. The health side of Yanglingquan (GB 34), Xuehai (SP 10), Hegu (LI 4), Houxi (SI 3) were selected and the needles were retained for 30 min. The acupuncture was given for 6 times. The evaluation was performed by using visual analogue scale (VAS) 2 h, 4 h, 6 h, 12 h, 24 h, 48 h and 72 h after surgery. The use of analgesics after surgery was recorded in the two groups, and the blood supply and survival rate of severed finger were evaluated.

RESULTSCompared between the two groups, the VAS 4 h, 6 h, 12 h, 24 h and 48 h after surgery in the observation group was lower than that in the control group (all P<0. 05); the use frequency of analgesics in the observation group was lower than that in the control group (P<0. 05); the abnormality rate of blood supply in the observation group was lower than that in the control group (P<0. 05).

CONCLUSIONAcupuncture can significantly relieve postoperative pain of replantation of severed finger, and reduce the occurrence rate of abnormal blood supply, which is worthy of clinical promotion.

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.

AIM:To research the characteristics of ventricular electrophysiology in right ventricular rapid pacing-induced congestive heart failure (CHF) dogs. METHODS:Dogs (n = 16) were randomly divided into 2 groups:the control (n = 7) and the CHF group (n = 9) induced by rapid right ventricular pacing at 240 pulse·min-1 for 4 to 5 weeks. The electrophysiologic parameters were evaluated by the technique of standard electric stimulation and monophasic action potential (MAP) recording. RESULTS:(1) Ventricular effective refractory period (VERP), ventricular MAP duration (MAPD90), ventricular late repolarization duration (VLRD) and intra- ventricular conduction time (IVCT) were prolonged by 26％ (P ＜ 0. 01), 43％ (P ＜ 0. 01), 318％ (P ＜ 0. 05), and 19％ (P ＜ 0. 01), respectively in CHF group. (2)The ratio of VERP to MAPD90(VERP/MAPD90) was decreased by 13％ (P＜0.05) in CHF group. (3) The dispersion of ventricular recovery time (VRT - D) was increased by 185％ (P ＜0. 01) in CHF group. (4) The ventricular fibrillation threshold (VFT) was decreased by 48％ (P ＜ 0. 01) in CHF group. CONCLUSION:The abnormal electrophysiological changes in the CHF condition may be contributing factors of lethal ventricular arrhythmias and sudden cardiac deaths in CHF.
