Based on the number of brucellosis cases reported from the national infectious diseases reporting system in Inner Mongolia from 2000 to 2007, a model was developed. Theories of spatial statistics were used, together with knowledge on infectious disease epidemiology and the frame of Bayesian statistics, before the Bayesian spatio-temporal models were respectively set. The effects of space, time, space-time and the relative covariates were also considered. These models were applied to analyze the brucellosis distribution and time trend in Inner Mongolia during 2000-2007. The results of Bayesian spatio-temporal models was expressed by mapping of the disease and compared to the conventional statistical methods. Results showed that the Bayesian models, under consideration of space-time effect and the relative covariates (deviance information criterion, DIC=2388.000) ,seemed to be the best way to serve the purpose. The county-level spatial correlation of brucellosis epidemics was positive and quite strong in Inner Mongolia. However, the spatial correlation varied with time and the coefficients ranged from 0.968 to 0.973, having a weakening trend during 2000-2007. Types of region and number of stock (cattle and sheep) might be related to the brucellosis epidemics, and the effect on the number of cattle and sheep changed by year. Compared to conventional statistical methods, Bayesian spatio-temporal modeling could precisely estimate the incidence relative risk and was an important tool to analyze the epidemic distribution patterns of infectious diseases and to estimate the incidence relative risk.

OBJECTIVETo explore the central mechanism of moxibustion on analgesic effect.
METHODSMale Wistar rats were screened by pain threshold value before making model, and 48 rats whose pain threshold was (250 +/- 25) g were selected. Twelve male Wistar rats were randomly selected as a normal group. For the rest rats the rheumatoid arthritis (RA) model was duplicated by raising in a windy, cold and wet environment combined with injection of Freund's complete adjuvant (FCA), and then they were randomly divided into a model group, a moxibustion group and a moxa volatile oil group, 12 rats in each group. The moxibustion and the moxa volatile oil igroup were treated with moxibustion and moxa volatile oil at "Shenshu"(BL 23) and "Zusanli"(ST 36), respectively, for 15 days. No interventions were added on the model group and the normal group. The pain threshold in Iinjured foot and the expression of hypothalamic POMC mRNA and PDYN mRNA in rats were observed.
RESULTSCompared with the normal group, the pain threshold and the expression of hypothalamic POMC mRNA and PDYN mRNA in the model group were increased (all P < 0.01). Compared with the model group, the pain threshold and the expression of hypothalamic POMC mRNA and PDYN mRNA in the moxibustion group were increased significantly (all P < 0.01), but no statistically significance in the moxa volatile oil group (P > 0.05). Compared with the moxa volatile oil group, the above-mentioned observative indices in moxibustion group were all increased significantly (all P < 0.01).
CONCLUSIONMoxibustion has obvious analgesic effect and its mechanism may be related to the increasing expression of hypothalamic POMC and PDYN mRNA through the warming effect of moxibustion.

OBJECTIVETo investigate the application of prospective space-time scan statistic in the early stage of detecting infectious disease outbreaks.
METHODSThe prospective space-time scan statistic was tested by mimicking daily prospective analyses of bacillary dysentery data of Chengdu city in 2005 (3212 cases in 102 towns and villages). And the results were compared with that of purely temporal scan statistic.
RESULTSThe prospective space-time scan statistic could give specific messages both in spatial and temporal. The results of June indicated that the prospective space-time scan statistic could timely detect the outbreaks that started from the local site, and the early warning message was powerful (P = 0.007). When the merely temporal scan statistic for detecting the outbreak was sent two days later, and the signal was less powerful (P = 0.039).
CONCLUSIONThe prospective space-time scan statistic could make full use of the spatial and temporal information in infectious disease data and could timely and effectively detect the outbreaks that start from the local sites. The prospective space-time scan statistic could be an important tool for local and national CDC to set up early detection surveillance systems.

OBJECTIVETo investigate the expression of TGF-betaR I, Smad2, Smad3 and Smad7 in keloids, normal scars and normal skins. Discuss the significance of these proteins in the course of keloid.
METHODSImmunohistochemistry method was used to detect the expression intensity and distribution of these proteins in above 3 kinds of different tissues in 44 cases. Statistics was used to analyze the data.
RESULTSThe expression of TGF-betaR I were much stronger in keloid than in the other two tissues. The expression of Smad7 were lower in keloids. The increase expression of Smad2,3 were not obvious, but they were found to accumulate in the nucleus.
CONCLUSIONSThe results indicate that over-expression of TGF-betaR I, low-expression of Smad7 and accumulation of Smad2,3 may be one of the etiological factors of keloids. This research may provide a new idea to prevent and treat keloids or other fibrosis diseases in the future.

OBJECTIVEApplication of Knox method was discussed in exploring temporal-spatial cluster for infectious diseases.
METHODSThe theory of Knox method was introduced in detail. As an example, the temporal-spatial cluster of epidemic cerebrospinal meningitis cases from April to May in 2005 was explored in Beijing and the statistical process of Knox method was clearly demonstrated with related results well interpreted.
RESULTSOnly when time and distance threshold values were set as 13 days and 29.67 km, potential temporal-spatial cluster could be detected in epidemic cerebrospinal meningitis cases.
CONCLUSIONAccording to the characteristics of the epidemics, under Knox method, if appropriate threshold values of time and distance were chosen, information on temporal-spatial cluster of infectious diseases could be obtained. According to the records of different time and distance threshold values, the nature of an infectious disease might be explored. Thus Knox method could help us to strengthen the early warning system on infectious disease control strategy.

Application of Rogerson Spatial Pattern Surveillance Method was discussed in real-time surveillance and early monitoring for infectious diseases. Theory of Rogerson Spatial Pattern Surveillance Method was introduced in detail. Data from the program on 'Monitoring epidemic cerebrospinal meningitis with Rogerson Spatial Pattern Surveillance Method' by the Chinese Center for Disease Control and Prevention provided evidence as how to choose crucial parameters such as K, H, n0 and tau, how to simulate surveillance process and how to interpret results. Rogerson Spatial Pattern Surveillance Method seemed to be able to continuously monitor the changes of infectious diseases. New cases could be added to this model at any moment and this model could provide early warning information in time when the excess of cases occurred. Simultaneously it could provide the time and site of the extra cases. Rogerson Spatial Pattern Surveillance Method could implement dynamic and real-time surveillance for infectious diseases. Simultaneously it could avoid the problem of multiple tests that causing large type I error. It greatly helped in providing reliable information for controlling infectious diseases in early epidemic period. Hence,it had important value of application in early warning on infectious diseases.
