To study the relationship between HLA DRB1*07 and the susceptibility to HBV in the Han nationality in Guangdong Province. 100 chronic HBV carrier individuals, 21 HBV spontaneously cleared individuals and 70 HBV unexposed individuals all of Han nationality in Guangdong Province were entered in this study. The expression of HLA DRB1*07 alleles were detected by polymerase chain reaction sequence specific primer, and IFN ? and IL 4 levels in plasma of HBV chronic carrier individuals were measured by using ELISA kits. The results showed that the positive rate of HLA DRB1*07 in chronic HBV carriers was 30%, which was markedly higher than that in HBV spontaneously cleared individuals(4 76%) and HBV unexposed individuals (8 5%) as well ( P

Objective To explore the method for establish the temporal lobe epilepsy model in SD rats with stereotactic technique and to study the characteristic of electroencephalography (EEG) after epileptic seizure. Methods Kainic acid was injected into right hippocampus via stereotactic technique in 20 rats, and the behavior of rat was recorded by a video camera. The electrical activity changes of brain were recorded by EEG in bilateral hippocampus, amygdala and frontal lobe. Results According to Racine's scale, 6 rats were typeⅤ,10 rats were type Ⅳ,3 rats were type Ⅲ,1 rat was type Ⅱ. The spike wave was originated from hippocampus and spread to amygdala and frontal lobe. Pathologic changes showed that prolonged seizures induced pyramidal cell loss and death in hippocampus. Conclusions The method to establish kainic acid induced temporal lobe epilepsy model with stereotactic technique was credible, economical and useful. The spike wave originated from hippocampus was the basic feature of EEG of temporal lobe epilepsy model in rats.

OBJECTIVETo explore lupus nephritis (LN) patients' monocyte chemotactic protein 1 (MCP-1) and urinary IP-10 (ulP-10) levels, the correlation between each clinical activity index and rheumatism syndrome, thereby proving objective evidence for microscopic typing of rheumatism syndrome.

METHODSTotally 60 LN patients were assigned to the rheumatism group (31 cases) and the non-rheumatism group (29 cases). Besides, 20 healthy volunteers were recruited as the normal control group. Clinical data and renal pathology were collected, and urinary levels of MCP-1 and IP-10 detected by ELISA. The correlation between rheumatism syndrome and each activity index as well as manifestations of clinical activities was comprehensively analyzed. Results (1) Patients in the rheumatism group were more liable to occur fever, serositis, edema, and hypertension (P<0.05). (2) Compared with the non-rheumatism group, patients in the rheumatism group exhibited much higher levels of 24 h protein quantification and blood urea nitrogen, higher levels of uMCP-1 and ulP-10. Microscopic hematuria, anti-ds-DNA, anti-Sm, the positive rate of AnuA, scores of SLEDAI and BILAG were higher in the rheumatism group than in the non-rheumatism group (P<0.05). Levels of plasma albumin and complement C3 were lower in the rheumatism group than in the non-rheumatism group (P<0.05). (3) The average activity index (AI) of the renal pathology was higher in the rheumatism group than in the non-rheumatism group. The most frequent pathological type of rheumatism group was type IV of LN.

CONCLUSIONSMore severe renal damage and immune abnormality occurred in LN patients of rheumatism syndrome. Rheumatism syndrome is closely correlated to clinical activity indices.

Objective To observe the effects of tetra-atsenic oxide (As4O6) on the proliferation, migration and invasion of human breast cancer MCF-7 cells; To explore its potential mechanism. Methods The human breast cancer MCF-7 cells were regarded as the research object and cultured in vitro, with different concentrations of As4O6 using to intervene in MCF-7 cells. The cell proliferation was detected by MTT assay; the flow cytometry and wound-healing assay were used to detect the cell apoptosis and migration, respectively. The expressions of Cyclin E1, Cyclin A2, Caspase 3, p21 and MMP-9 mRNA were accessed by semi quantitative RT-PCR. Results As4O6 had a significant inhibitory effect on the proliferation of MCF-7 cells in a dose dependent manner. Compared with the control group (0 μmol/L), the apoptosis rate increased significantly when the concentration of As4O6 was 9, 12, 15 μmol/L (P<0.01). Either As4O6 at high (3 μmol/L) or low (1 μmol/L) concentration could effectively inhibit the migration of MCF-7 cells (P<0.01). With the increasing concentration of As4O6, the expressions of Cyclin E1, Caspase 3, and p21 mRNA significantly increased, while the expressions of Cyclin A2 and MMP-9 mRNA significantly decreased (P<0.05, P<0.01). Conclusion As4O6 can significantly inhibit the proliferation, cycle, invasion and migration of breast cancer MCF-7 cells, and the mechanism may be related to the increase of expressions of cyclin E1, caspase 3, p21 and inhibition of expressions of cyclin A2 and MMP-9.

Objective To explore the expression of SP-A in surface active substance of sputum pulmonary of dysfunctional venti-latory weaning response patients and to study changes of expression of SP-A and oxygenation index ,arterial partial pressure of oxy-gen .Methods The mechanical ventilatory patients were divide into dysfunctional ventilatory weaning response group (group A) and easily weaning group(group B) ,then collected sputum from ventilators at different times :on the first day ,two and seven days after using ventilators .Used ELISA to test level of SP-A and oxygenation index ,arterial partial pressure of oxygen in sputum of group A and group B .Results For group A ,SP-A content oxygenation index and arterial partial pressure of oxygen were significantly less than those for group B(P<0 .05);after two days ,for group A ,SP-A content in sputum was significantly less than that on the first day ,and SP-A content in sputum was significantly less than that on the second day (P<0 .05);two days later ,oxygenation index and arterial partial pressure of oxygen were significantly lmore than those on the first day (P<0 .05) and there was no statistical difference in oxygenation index and arterial partial pressure of oxygen between the seventh day and the second day (P>0 .05) .Con-clusion Dysfunctional ventilatory weaning response and lung injury related to ventilator can be diagnosed early through the test of SP-A content in sputum ,which provides a brand-new way and method of treatment in dysfunctional ventilatory weaning response and lung injury related to ventilator .
