Objective: To observe the gingival color of healthy Han nationality in Shanghai, so as to discuss the gingival color distribution and its influencing factors. Methods: The Chroma Meter CR-321 was used to obtain the CIE-1976-L* a* b* value in predefined testing spots of gingiva in healthy Han nationality in Shanghai. The gingival color distribution and the influences of age, sex on the gingival color were summarized. Results: We found that the L* values of attached gingiva of the median line(P=0.0061), free gingiva of central incisor(P = 0.0324), attached gingiva in the root of central incisor (P=0.029 7), and distal incisor attached gingiva (P=0.0324) in the female were significantly higher than those in the male; the a* b* values in attached gingiva of median line (P = 0.0083, P = 0.0020) were significantly higher than those in male; and the other a*, b* values were similar between the males and females. The color difference ΔE between free gingiva and attached gingiva was > 2 (P<0.01). ΔL*2 had the greatest influence on ΔE, with the standardized regression coefficient being b' = 0.88216, followed by Δa*2 and Δb*2 in order, with b' being 0.23097 and 0.06632, respectively. L*, a*, and b* values had no obvious relation to age. Conclusion: It is indicated that sex and age have little influence on the color of gingiva in Han nationality in Shanghai. Obvious color difference exists between the free gingiva and the attatched gingiva.

Objective To investigate the possible risk factors for lead poisoning in order to prevent the lead poisoning in children.Methods One thousand and fifty-five children aged 5 months to 16 years who were outpatients in Beijing children′s hospital were chosen. Blood lead was analyzed by 3010-B lead analyzer for each child.Also the risk factors were recorded by using a standardized questionnaire.Results The mean level of blood lead was(110.1?41.9) ?g/L with the occurrence of lead poisoning (blood lead ≥100 ?g/L) at 43.51%.No difference were found in blood lead level among different age groups.Several environmental and social factors were found to be related to lead poisoning in children,such as non-balanced diet,rarely hand washing,frequent eating crisp foods,not frequency of calcium and zinc supplementation and frequency of room decoration.Conclusion Unhealthy dietary and life styles contribute to lead poisoning in children.

OBJECTIVETo explore the alterations of after depolarization and triggered activity in myocardiac muscle during progression of mouse aortic stenosis.

METHODSAfter the establishment of mouse aortic stenosis model, the heart was collected and intracellular potential was recorded using standard glass microelectrode. After the recording, the action potential (AP), early after depolarization (EAD), delayed after depolarization (DAD) in papillary muscles were analysed.

RESULTS(1) Compared with that of time-matched control mice, there were no changes of the action potoutial duration at 90% repolarization(APD90) in model mice at 2 and 5 weeks, whereas the APD90 was progressively prolonged at 9 and 13 weeks. (2) During the 30 minites of the experiment, spontaneous EADs and DADs were frequently present in medel mice at 9 and 13 weeks, were not in control and model mice at 2 and 5 weeks. (3) Compared with those of control group, EADs and DADs triggered by hypokalaemia or isoproterenol were increased significantly. The incidence rate of triggering EADs and DADs was progressively increased over time.

CONCLUSIONEAD, DAD and trigger activities increase gradually during the process of aortic stenosis, and it suggests that the myocardium electrical-instability is markedly increased in the insult hearts.

OBJECTIVETo find the characteristic parameters from electrocardiogram (ECG) which is most related to pathological progress, surface ECG was performed in mice at 2, 5, 9 and 13 week post surgery.

METHODSElectrocardiogram recordings: The mice were anaesthetized with tribromoethanol (250 mg/kg, i.p.). Lead II surface ECG were acquired by using the Biopac System MP150 at a rate of 5 kHz.

RESULTS(1) No arrhythmia was observed in Sham and 2-week Band mice. Spontaneous arrhythmias were observed in ECG recordings, with an incidence of 15%, 28% and 63% in 5-, 9- and 13-week Band mice, respectively. Tachyarrhythmias, such as frequent premature ventricular extrasystole, bigeminy, trigeminy, and paroxysmal tachycardia were found. (2) Analysis of ECG recordings revealed a significant prolongation of QT and QTc intervals. Compared with age-matched Sham mice, the increment in QT and QTc intervals was 20.4%, 32.7%, 49.7%, 61.0% and 27.1%, 32.1%, 43.9%, 59.1% at 2, 5, 9 and 13 week, respectively (P < 0.01). (3) The characteristic change in electrocardiogram was on the J wave. The amplitude of J wave was upward in Sham mice, and it was significantly flattened or inverted in Band mice. (4) Except that RR interval at 2 week showed a slight decrease, there was no significant change in PR interval and RR interval in Band mice.

CONCLUSIONIn the present study, we found that the increase incidence of spontaneous arrhythmias, prologation of QT interval and changes in the amplitude of the J wave in the surface ECG during progression of mouse cardiac hypertrophy and failure, and the progressive pattern indicated that a gradual aggravation of the ventricular repolarization delay in this mouse model.

Clinical, neuroimaging, and pathologic studies suggested that a variety of nonmotor symptoms, such as olfactory dysfunction, dysautonomia, and mood and sleep disorders, can precede the typic motor features of Parkinson disease (PD) by years and, perhaps, even decades. The period when these symptoms arise can be referred as the premotor phase of the disease. This paper reviewed the conception, clinical manifestation, pathology, diogose of the premotor phase of early Parkinson disease.
