AIM: In order to explore the pathogenesis of ulcerative colitis (UC), an experimental colitis in mouse was induced by the hapten dinitrochlorobenzene (DNCB), and the activity of leukocyte migration inhibitory factor (LMIF) was measured at the same time. METHODS: 67 BALB/c mice were randomly divided into control (60% ethanol) and DNCB groups. After they were sensitized by smearing 3.3% DNCB on the abdominal skin, they were challenged with DNCB at concentration of 0.1%, 0.2% and 0.4% respectively by instillation once a day. The weight, stool viscosity and hematochezia were observed and accumulated as disease active index (DAI) score. The pathological changes in colon tissue were judged macropathologically and by means of microscope. LMIF activity was determined by the absorbance (A) of migrated leukocytes. RESULTS: Compared to control group, the increases in DAI accumulate score, pathologic score, and LMIF activity in DNCB groups were observed. CONCLUSION: Mouse colitis was induced by DNCB, which was accompanied by an increase in LMIF activity. [

OBJECTIVETo investigate the protective effect and action mechanism of petroleum ether extracts from Saussurea involucrate on brain tissues of hypoxia rats under constant pressure and closed conditions.

METHODThe PESI dosage-dependent experiment for hypoxia rats was conducted under constant pressure and closed conditions by intraperitoneally injecting 125, 250, 500 mg x kg(-1) to finalize that the optimum dosage is the high dose of PESI. Afterwards, 90 Wistar rats were randomly divided into the hypoxic model group, the acetazolamide 250 mg x kg(-1) group and the PESI high dose group. Each group was further divided into three subgroups according to different hypoxia times, with 10 rats in each subgroup. Under the same hypoxia and administration conditions, the rats were sacrificed after 0, 3, 6 h respectively. Their brain samples were collected for common pathological observation and immunohistochemical staining of HIF-1alpha. Real-time RT-PCR was used to detect HIF-1alpha, EPO, HO-1 and Caspase-3 gene expressions. And the Western blot assay was adopted to detect HIF-1alpha protein expression.

RESULTThe brain tissues of the hypoxia model group were severely damaged with the increase in the hypoxia time. The acetazolamide group and the PESI high does group were damaged in a much lower degree. According to the gene expression and the Western blot assay, high dose of PESI could inhibit HIF-1alpha expression. According to the pure gene expression test, high dose of PESI could increase EPO and HO-1 mRNA expressions, but inhibit Caspase-3 mRNA expression.

CONCLUSIONPESI's protective mechanism for brain tissues of hypoxia rats under constant pressure and closed conditions may be related to its effects in inhibiting HIF-1alpha expression, increasing EPO expression and resisting cell apoptosis.

OBJECTIVE: To explore the applicability of integration between three-dimensional (3D) facial and dental data to evaluate the nasolabial morphology variation before and after the cross-arch fixed restoration of the maxillary implant-supported prostheses. METHODS: Twelve patients (4 women and 8 men), mean age (54.82±5.50) years (from 45 to 62 years) referred to the Department of Oral Implan-tology, Peking University School and Hospital of Stomatology, were selected and diagnosed with edentulous maxilla. For all the patients, 4 to 6 implants were inserted into the maxilla. Six months later, the final cross-arch fixed prostheses were delivered. The 3D facial images were collected before and after the final restoration. The 3D data of prostheses were also captured. All the 3D data were registered and measured in the same coordinate system. Then the displacement of all the landmarks [cheilion left (CHL), cheilion right (CHR), crista philtri left (CPHL), crista philtri right (CPHR), labrale supe-rius (LS), subnasale (SN), stomion (STO), upper incisor (UI), upper flange border of the prostheses (F-point, F)], and the variation of the distances between these landmarks (SN-LS, CPHR-CPHL, CHR-CHL, LS-STO) were analyzed and compared. RESULTS: The consistency test among three measurements of the length of F-SN indicated that the integration method of the dental prostheses and soft tissue had the good repetitiveness, ICC=0.983 (95%CI: 0.957-0.995). After wearing the final cross-arch maxillary implant-supported prostheses, all the landmarks on the soft tissue moved forward. The nasal base area changed minimally, and the shift of SN in the sagittal direction was only (0.61±0.44) mm. But the sagittal shift of LS was (3.12±1.38) mm. In the vertical direction, SN, LS, CPHL, and CPHR moved upward. But STO, CHL, and CHR moved downward a little. Except for the slight decrease of the length of philtrum (SN-LS), the length of CHL-CHR, CPHL-CPHR, and the height of upper lip were increased together (P < 0.01). In the direction of Z axis, the strong correlations were found not only between the movements of SN and F (r=0.904 3) but also between the movements of LS and UI (r=0.958 4). CONCLUSION The integration method of 3D facial and dental data showed good repetitiveness. And the strong correlations between the landmarks of prostheses and nasolabial soft tissue in the sagittal direction were found by this new method.

OBJECTIVETo explore the effects of hepatitis B immune globulin (HBIG) in prevention of mother-to-infant hepatitis B virus (HBV) transmission.

METHODA total of 279 pregnant women positive for HBsAg alone or for both HBsAg and HBeAg were enrolled into this study from January 2001 to May 2005. They were respectively divided into two groups at random, namely, only HBsAg-positiveexperimental group (n = 80), only HBsAg-positive control group (n = 60), both HBsAg and HBeAg-positive experimental group (n = 79) and both HBsAg and HBeAg-positive control group (n = 60). The two experimental groups were injected with HBIG once every four weeks until labor. The two control groups received no HBIG. The infants received intramuscular HBIG 16 hours after birth and two weeks later, in addition to routine immunization with hepatitis B vaccine. The infants were followed up and HBsAg was determined.

RESULTSThe HBsAg infection rates of babies in the four groups were respectively 3%, 13%, 10%, 32%. The infection rate of the infants whose mothers were injected with HBIG was significantly lower than that of the control group.

CONCLUSIONThe HBIG could effectively prevent HBV transmission from mothers to infants and reduce the HBV infection rate.
