Objective To investigate the correlation between toll-like receptor 9 (TLR9) gene 2848G/A polymorphism and primary antineutrophil cytoplasmic antibodies (ANCA) associated small vasculitis (AAV). Methods A case-control study was performed among 135 patients diagnosed with AAV and 140 disease-free control and we test the serum biochemical parameter. Polymorphism was analyzed by polymerase chain restricted fragments length polymorphism. As for statistic method, according to the character of data, we performed t-test, chi-square test, Spearman grade related analysis and one-way ANOVA. Results ① The frequencies of AA, GG, GA genotype of TLR9 2848 in AAV patients were 14.07%, 38.52%, and 47.71%, respectively; ② Significant increase in IgM was observed in AA genotype than GG+GA genotype in AAV patients (F=4.561, P<0.05). ③ There was no significant difference between AI and CI in AA, GA and GG genotype in AAV patients (F=2.115, 0.760, P>0.05). Conclusion AA, GA and GG genotypes are detected in TLR9 2848G/A in patients with AAV in Guangxi, without significant correlation with susceptibility to primary AAV in Guangxi.

Objective To evaluate the influence of epimeric glycyrrhizic acid on production of endothelin-1 (ET-1) in the lungs induced by ischemia-reperfusion(I/R) injury.Methods Twenty healthy long-ear white rabbits of both sexes, weighing 1.1-2.1kg were randomly divided into 2 groups: group I I/R alone ( n = 10) and group II I/R + epimeric glycyrrhizic acid (n = 10). The animals were anesthetized with thiopental 25 mg?kg-1 and tracheotomized and mechanically ventilated (FiO2 = 100% , VT = 10-13 ml?kg, RR = 20-30 bpm, I:E= 1: 1.2). Anesthesia was maintained with fentanyl, thiopental and vecuronium. Femoral artery was cannulated for continuous direct BP monitoring. MAP was maintained at 70-90 mm Hg during experiment. Right interval jugular vein was cannulated. Catheter was inserted into right atrium for fluid administration, blood sampling and right atrial pressure monitoring. Chest was opened and the hilum of right lung was mass-ligated to induce ischemia for 60 min and then released for reperfusion for 60 min. Epimeric glycyrrhizic acid 30 mg?kg-1 was given iv 30 min before ischemia of the right lung. Blood samples were taken from right atrium and femoral artery for determination of ET-1 concentration before ischemia of right lung (T0) and 1 and 5 min after right lung started being perfused (T1 , T2). At the end of 60 min reperfusion of the right lung, the animals were sacrificed and lungs (right and left) were removed for electron microscopic examination. Results In group 1 at T, the ET-1 levels in the blood from both femoral artery and right atrium were significantly higher than the baseline (T0) and the ET-1 concentration in the blood from femoral artery was significantly higher than that from right atrium. In group II there was no significant difference in blood ET-1 concentration between T0 and T, .Conclusion Ischemia-reperfusion induces increased production of ET-1 in the injured lung. Epimeric glycyrrhizic acid can inhibit the increase in the production of ET-1 in the induced by I/R.

With reverse transcriptase PCR, the transcripton of copper homeostasis relative gene Afe0329 in Acidithiobacillus ferrooxians standard strain ATCC23270 was investigated. The further analysis of genes in this transcripton was analyzed employed by Vector NTI, Blast, TMHMM Server, PSORTb software and so on. From the DNA of different strains, the transcripton of Afe0329 was amplified using special primer pairs to identify the universality of it in the genome of A.ferrooxidans strains. The results showed that gene Afe0330 and Afe0331 were cotranscribed with Afe0329, and they were in a single transcripton. Gene Afe0329 was supported to express a P1b3-type ATPase which is a heavy metal ion pumping transmembrane protein, protein AFE0330 which expressed by gene Afe0330 was a cytoplasmic protein, no significant ho- mologous sequences of Afe0330 or Afe0331 had been obtained by Blast analysis. And the transcripton of Afe0329 was universal in genome of A. ferrooxidans strains.

OBJECTIVETo detect the effect of Nocardia rubra cell wall skeleton (Nr-CWS) on tumorigenicity induced by TC-1 cells and to clinically study anti-human papillomavirus effect of Nr-CWS in lower genital tract of women.
METHODSTumor model was established by injecting TC-1 cells subcutaneously in SCID mice, then divided them into 3 groups randomly and injected with isovolumetric physiological saline, 60 micrograms/ml Nr-CWS and 120 micrograms/ml Nr-CWS respectively, the growth of tumors was measured one week later. Nr-CWS was applied on 45 HPV positive women whose TCT test was normal and without cervical erosion 2-3 days after menstruation. HPV was detected again 3 months later to explore the effect of Nr-CWS on HPV infection in female lower genital tract.
RESULTSThe animal experiment showed the weight of transplanted tumors in treated group was less than that of control group (chi2=12.5, P= 0.002). The tumor inhibition rate was 59.1 percent and 84.2 percent in the groups treated with Nr-CWS 60 and 120 micrograms/ml Nr-CWS; the results of HPV detection in 23 out of the 45 cases (51.1 percent) became negative after the 3-month treatment; the viral load was reduced in 9, and there was no change in viral load in 13 cases. Significant difference was found between the rates of undetectable viral load and the natural viral disappearance rate (P less than 0.05).
CONCLUSIONNr-CWS has an inhibitory effect to TC-1 cell tumorigenesis and clinical application of Nr-CWS may eliminate the HPV infection in lower genital tract of a considerable proportion of women with HPV infection.

The main mineral component of natural tooth was determined as calcium apatite many years ago; most of them exist in the form of hydroxyapatite with different crystallites. If a tooth decayed, the crystalline of hydroxyapatite would be changed and decomposed. In our experiment, a natural tooth with caries was measured by high resolution XRD equipment: X'pert Pro. Three spots which included normal enamel, normal dentin and caries tissue were analyzed. The results showed that tooth was a kind of biological mixed crystal composed of many crystal phases, the main crystal phase was hydroxyapatite. From normal enamel to normal dentin and to caries tissue, the length of the a-axis of hydroxyapatite crystallite increased, the length of the c-axis of hydroxyapatite crystallite remained unchanged. The crystal sizes were: normal enamel D002 = 27.600 nm; normal dentin D002 = 16.561 nm; caries tissue D002 = 13.163 nm. Crystallinity: normal enamel>normal dentin>caries tissue. According to our experiment, tooth could be conveniently studied by high resolution microdiffracion XRD equipment.

Objective To evaluate the value of MR angiography in thrombolytic therapy of acute ischemic stroke. Methods According to inclusion criteria, 65 patients who also having large vessel occlusion were selected, and they were performed rt-PA treatment (38 patients) and routine treatment (27 patients) within 3-6 hours of onset of symptoms, respectively. Mann-Whitney U test and chi square test were performed to compare the clinical and MR imaging baseline index and the clinical outcome between the two groups respectively. Clinical outcome was assessed after 3 months using a dichotomized modified Rankin scale score.Data were also compared with the combined analysis of the ATLANTIS, ECASS, NINDS rt-PA trials. Resets The difference of clinical outcome in 3 months between the two groups was significant (P < 0. 05) and the median of the two group was 1 and 3, respectively. The ratio of favorable outcome (mRS 0-1) in the two groups was 52. 6% (20/38) and 33.3% (9/27), respectively. Conclusion MR angiography plays an important role in thrombolytic therapy of acute ischemic stroke and it should be used to consummate the conventional inclusion criteria, the patients with large vessel occlusion should be treated by rt-PA.
