Journal of Peking University(Health Sciences) 2003;0(05):-
Objective: To study characteristics of children's EEG complexity at different ages and in different physiological states.Methods: The continuous 24 hour EEG recordings were obtained from 16 electrodes in 45 essential healthy children between the ages of 0 to 15 years. EEG complexity was analyzed by non linear measure in 7 states: awake with eyes opened, awake with eyes closed, NREM (nonrapid eye movements) sleep including stages ⅠandⅡ (light sleep), ⅢandⅣ(deep sleep) and REM (rapid eye movements) sleep. Meanwhile, the correlation was analyzed between complexity and ages.Results: (1)The global EEG complexity in state of being awake with eyes opened was greater than that with eyes closed;that in wakefulness state was greater than in sleep state. The EEG complexity gradually decreased with the increase of deep sleep in NREM sleep state.The complexity in REM sleep state was greater than that in deep sleep state, but lower than in wakefulness state. (2) The global EEG complexity was positively related to ages in state of being awake with eyes opened, state of being awake with eyes closed, light sleep, and not related to ages in deep-sleep state and REM sleep state.(3)In every brain area EEG complexity was positively related to ages in state of being awake with eyes closed .In paracentral region EEG complexity was positively related to ages in states of being awake with eyes opened and light sleep.Conclusion: The EEG complexity was used to study the brain dynamical characteristics in different physiology states and the relationship between encephalic electric activity and brain development. It can be used as an objective index to evaluate the function and development of brain.

This article introduces the experience of CHEN Ying-yi, chief physician and one of the teacher of the fourth group of inheriting academic experience of veteran TCM experts of China, in treating perimenopausal women’s dysfunctional uterine bleeding. Chen holds that the basic pathogenesis of perimenopausal dysfunctional uterine bleeding is kidney deficiency with fever or stagnation. Treatment should focus on replenishing kidney and using the traditional Chinese drug by stages. The methods of stopping bleeding, clearing origin and reinstating the status quo are used flexibly. In clinic, it should grasp the key points of syndrome differentiation, and modify the therapy in accordance with the symptoms. Validated by clinical application, Chen’s experience has satisfactory curative effect and reference values for the treatment of perimenopausal women’s dysfunctional uterine bleeding.

BACKGROUND:Radiation-induced brain injury has recently become an increasing area of research, in particular in animal experimental studies. Domestic and international researches show that there have been no uniform scanning parameters used for examination of animal models of radiation-induced brain injury by magnetic resonance imaging. In this study, we performed magnetic resonance imaging in rabbits to determine related sequence parameters. OBJECTIVE:To establish the New Zealand rabbit models of radiation-induced brain injury, and obtain the brain magnetic resonance images of rabbits using LOOP7 coil, so as to provide experimental evidence for diagnosis of radiation-induced brain injury by magenetic resonance imaging. METHODS:Each of T2-weighted imaging, diffusion tensor imaging, magnetic resonance spectroscopy and magnetic susceptibility-weighted imaging were performed several times through the use of LOOP7 coil, to determine the optimal scanning parameters for each sequence. Rabbit models of radiation-induced brain injury were established and then their right hemispheres were irradiated using 6 MV X-rays at a single dose of 40, 80 and 120 Gy. The daily performance and dynamic magnetic resonance signs of rabbits were observed. The brain tissue was taken for pathological examination once abnormal magnetic resonance findings were observed or after 20 weeks of folow-up. RESULTS AND CONCLUSION:Only one rabbit model in the 40 Gy group had subdural hemorrhage. In the 80 Gy group, abnormal T2-weight imaging signals were observed in al rabbit models, which were pathologicaly confirmed as scattered degenerated neurons and infiltrated neutrophils. The abnormal signals that gradualy expanded over time were seen in rabbits from the 120 Gy group by magnetic resonance imaging and were pathologicaly confirmed as radiation-induced brain injury loci. The results confirm that establishing rat models of radiation-induced brain injury using radiation therapy system can better simulate the pathological process of radiation-induced brain injury; moreover, this model can be applied to receive routine magnetic resonance examination with LOOP7 coil.

Objective To compare the efficacy of intralesional glucocorticoid injection with a needle-free injector versus an ordinary injector for the treatment of keloid. Methods A total of 60 patients with keloid were enrolled and randomly divided into two groups by using a random number table to receive intralesional injection of compound betamethasone with a needle-free injector(n=31)or an ordinary injector(n=29). The injection was given at a dose of 0.2 ml/cm3 once every 3 weeks for 3 sessions. Parameters for therapeutic efficacy were assessed, adverse reactions were recorded, and clinical pictures were taken before and after each treatment. Statistical analysis was carried out by the Mann-Whitney U test and chi-square test with the SPSS 19.0 software. Results Compared with the ordinary injector group, the needle-free injector group showed significantly different injection time during the first and second treatment (U=299.000, 773.500, respectively, both P=0.000), as well as duration of pain after the first injection(U=730.000, P=0.003). After three sessions of treatment, there was a significant difference in the volume, height, hardness of keloid, scores for pain, itching and appearance, and number of injection points between the needle-free injector group and ordinary injector group (U=295.000, 336.500, 264.000, 464.000, 451.500, 308.000, 233.500, P=0.001, 0.007, 0.000, 0.041, 0.043, 0.003, 0.001, respectively). No significant differences were observed in the incidence of adverse reactions between the two groups(all P>0.05). Moreover, the interval for lesion recurrence was significantly shorter in the needle-free injector group(11.8 days, 95%CI:10.96-12.6 days)than in the ordinary injector group(21.2 days, 95%CI:13.96-28.45 days). Conclusion Compared with the ordinary injector, the needle-free injector shows better efficiency for the treatment of keloid with decreased difficulty in injection and improved compliance in patients.

Background:Ulcerative colitis(UC)is a chronic and nonspecific intestinal inflammatory disease and its pathogenic mechanism has not yet been clarified. Intestinal mucosal immune function disorder may play a key role in the pathogenesis of UC. Aims:To investigate the effects of Wumeiwan on expressions of δ-opioid receptor(DOR),β-arrestin1 and Bcl-2 in rats with colitis. Methods:Fifty-six Sprague-Dawley rats were randomly divided into model group,Wumeiwan group, mesalazine group and blank group. Rats in model group,Wumeiwan group and mesalazine group were administered intrarectally with 5% TNBS and 50% ethanol to induce experimental colitis. After colitis models were established,rats in Wumeiwan group and mesalazine group were administered intragastrically with Wumeiwan and mesalazine suspension, respectively,and rats in model group and blank group were given intragastrically with 0. 9% NaCl solution,all for 15 days. On day 16,all the rats were sacrificed and colon samples were obtained. Protein and mRNA expressions of DOR,β-arrestin1 and Bcl-2 in colonic tissue were determined by immunohistochemistry and real-time PCR,respectively. Results:The inflammatory injury in colonic tissue of rats with experimental colitis was significantly attenuated when treated with Wumeiwan,Protein and mRNA expressions of DOR,β-arrestin1 and Bcl-2 in colonic tissue of model group were significantly higher than those of blank group(P < 0. 05). Protein and mRNA expressions of DOR,β-arrestin1 and Bcl-2 in colonic tissue of Wumeiwan group and mesalazine group were significantly lower than those of model group(P < 0. 05), however,no significant differences were found between the two groups(P > 0. 05). Conclusions:DOR-β-arrestin1-Bcl-2 signal transduction pathway may play a central role in the pathogenesis of UC. Intervening this signaling pathway may be one of the mechanisms of attenuating UC by Wumeiwan.
