OBJECTIVETo explore the correlation of the gene polymorphisms of Toll-like receptor 2 ( TLR2) and TLR4 with the susceptibility and recurrence of condyloma acuminatum (CA).

METHODSUsing Snapshot, we detected the gene polymorphisms of TLR2 597(T/C), 1350(T/C), 15607(A/G), and 2258(G/A) and TLR4 896(A/G) and 1196(C/T) in the peripheral blood of 140 CA patients and 105 HPV-negative controls. We made comparisons between the CA patients and controls as well as between the cases of recurrent CA and those of non-recurrence at 6 months after treatment.

RESULTSThere were 72, 48, and 20 cases of genotype TT, TC, and CC of TLR2 597 (T/C), respectively, in the CA patients, as compared with 71, 31, and 3 cases in the controls. The gene frequency of mutant C was 31. 43% in the patients, significantly higher than 17.62% in the controls (χ2 = 12.04, P < 0.01), and it was 38.68% in the recurrent cases, remarkably higher than 27.01% in the non-recurrent cases (χ2 = 4.16, P < 0.05). There were 74, 49, and 17 cases of genotype TT, TC, and CC of TLR2 1350( T/C), respectively, in the CA patients, as compared with 73, 29, and 3 cases in the controls. The gene frequency of mutant C was 29. 64% in the patients, significantly higher than 16. 67% in the controls (χ2 =11.05, P < 0.01), and it was 36.79% in the recurrent cases, markedly higher than 25. 29% in the non-recurrent cases (χ2 = 4.18, P < 0.05). There were 44, 66, and 30 cases of genotype AA, AG, and GG of TLR2 15607(A/G), respectively, in the CA patients, as compared with 26, 58, and 21 cases in the controls. There was no significant difference in the gene frequencies of mutant G between the two groups (χ2 = 0.33, P > 0.05). No mutant genes of TLR2 2508 (G/A) or TLR4 896(A/G) and 1196(C/ T) were detected in either the CA patients or the controls. Linkage disequilibrium analysis showed a tight linkage between TLR2 597 (T/C) and 1350(T/C) (D' = 1, r2 = 0.93).

CONCLUSIONTLR2 597(T/C) is tightly linked to 1350(T/C), which is correlated with both the susceptibility and the recurrence of condyloma acuminatum.

Objective To analyze the antimicrobial susceptibility of Mycoplasma isolates for rational antimicrobial therapy. Methods BioM?rieux IST kit was used for identification and susceptibility testing of Mycoplasma strains.Results Mycoplasma was positive in 49.5% of the specimens tested.Of the Mycoplasma detected,Ureaplasma urealyticum(Uu)alone accounted for 74.7%,Mycoplasma huminis(Mh)alone accounted for 18.1%,and Uu+Mh was identified in 7.2% of the patients.The results of antimicrobial susceptibility testing showed that the Mycoplasma isolates were most susceptible to doxycycline (98.1%).Ciprofloxacin was the least active (17.3%).Conclusions Doxyeycline,josamycin,and clarithromycin can be used in the treatment of urinary tract infections caused by Mycoplasma.

OBJECTIVETo investigate whether the cardioprotective effect of hemin against ischemia/reperfusion (I/R) injury is through the inhibition of calpain activity, and to explore its underlying mechanism.

METHODSSixty-four SD rats were randomly divided into eight groups (n = 8): sham, I/R, MDL+ I/R, MDL, hemin + I/R, hemin, and ZnPP + hemin+ I/R, ZnPP. Iangendorff isolated rat heart perfusion model was used. The rat hearts were suffered from 40 min of ischemia followed by 30 min of reperfusion. After that, left ventricular developed pressure (LVDP) was recorded. Infarct size and release of lactate dehydrogenase (LDH) were measured. Calpain, heme oxygenase (HO), and caspase 3 activities were evaluated. Expression of calpastatin protein was detected by Western blot.

RESULTS(1) After suffered from ischemia/reperfusion, the calpain activity and caspase 3 activity increased. MDL28170, an inhibitor of calpain, prevented ischemia/reperfusion induced increases in LDH and infarct size, improved the LVDP recovery. (2) Compared with ischema/reperfusion rat hearts, pretreatment of hemin enhanced the HO-1 activity, decreased the calpain and caspase 3 activities, declined LDH release and infarct size, and improved LVDP recovery. (3) Ischemia/reperfusion reduced the expression of calpastatin protein in rat hearts, which was inhibited by hemin pretreatment. And HO-1 inhibitor could abolish the cardioprotection of hemin.

CONCLUSIONCardioprotective effect of hemin against ischemia/reperfusion injury is through the inhibition of calpain activity, the mechanism might be involved in the increase in calpastatin protein expression.

OBJECTIVETo compare the dissolution characteristics of colloidal silica and porous silica as the solid dispersion carrier, with baicalin as the model drug.

METHODThe baicalin solid dispersion was prepared by the solvent method, with colloidal silica and porous silica as the carriers. In the in vitro dissolution experiment, the solid dispersion was identified by scanning electron microscopy, differential scanning and X-ray diffraction.

RESULTThe solid dispersion carriers prepared with both colloidal silica and porous silica could achieve the purpose of rapid release. Along with the increase in the proportion of the carriers, the dissolution rate is accelerated to more than 80% within 60 min. Baicalin existed in the solid dispersion carriers in the non-crystalline form.

CONCLUSIONThe release behaviors of the baicalin solid dispersion prepared with two types of carrier were different. Among the two solid dispersion carriers, porous silica dissolved slowly than colloidal silica within 60 min, and they showed similar dissolutions after 60 min.

Baicalin extremely fine powder was made by using ball-mill and the effect of micronization on the micromeritics properties of baicalin was studied and analyzed. The microstructures of baicalin ordinary and extremely fine powder were compared by scanning electron microscope, differential scanning calorimeter and X-ray diffraction and the powder characteristic of them was investigated. The hygroscopicity was studied. The effect of micronization on the dissolution of baicalin was investigated. The results showed that the chemical constituents of baicalin were not changed after micronization with better compressibility. It was confirmed that micronization technology had a certain application value in promoting the insoluble component of baicalin absorption with higher dissolution.

Cirrhosis with portal hypertension is a common disease which has a significant impact on the quality of patients' life. Esophagogastric devascularization (EGDV) has been demonstrated to be an effective method to treat portal hypertension, however certain complications are associated with it. The purpose of this study was to evaluate the effectiveness and clinical outcome of the selective EGDV (sEGDV) for the treatment of portal hypertension. The study was conducted prospectively from Jan. 1 2011 to Dec. 31, 2012, and 180 patients were randomized to the sEGDV group (n=90) or the non-sEGDV (n-sEGDV) group (n=90). Patients' demographics, preoperative lab test results and operative details were comparable between the two groups. Postoperative and short-term complications were analyzed in two groups. There was statistically significant difference (P<0.01) in the PVF reduction between the two groups. Post-operative complications showed no statistically significant difference between the two groups in the incidence of bleeding, ascites, acute portal vein thrombosis, fever and hepatic encephalopathy. Mortality between two groups was comparable. The incidence of splenic fossa effusion after the surgery was lower in sEGDV group than in n-sEGDV group. There were no significant differences in the short-term follow-up data such as esophageal varices and portal hypertensive gastropathy (P>0.05). It is suggested that sEGDV is a safe, simple and effective surgical procedure. It has both the advantages of the shunt and devascularization because it preserves body's voluntary diversion. With the advantage of low incidence of postoperative complications, it is an ideal surgical approach for the treatment of portal hypertension.

P13-OMP (29.1). P13-OMP and OMP68 group challenged with P13 and P11 can be efectivly protected; P13-WCB group challenged with P13 and P11 can not be efectivly protected; the control group were died out. The P13-OMP and OMP68 of Bordetella bronchiseptica has good immunogenicity and protection, so the results of this study lay good theoretical foundation for OMP subunit vaccine.
