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 examine whether neonate′s cord blood T-lymphocytes is related to infant temperament.Methods Twenty-five healthy babies were randomly chosen in Changsha from Jul.2005 to Aug.2005 and their cord blood was drown when they were born. CD4+ and CD8+ counts, CD4+%, CD8+%, CD4+/ CD8+ratios were obtained using flow cytometry analysis. Infant temperament were measured after 1-4 months( mean age 2.52 months) with parent response to carey revised infant temperament questionnaire(EITQ/RITQ) administered.Results The percentage of CD4+ T-cell subsets to total lymphocytes correlated negatively with persistence scores (r=-0.43 P=0.033). However, CD8+%, CD8+ and CD4+ counts, CD4+/ CD8+ ratios were not correlated with temperament traits.Conclusions The lower CD4 %, the better infants' persistence.

OBJECTIVETo investigate the pathogenic factors of human cytomegalovirus (HCMV) infections.
METHODSTotally 36 serum samples were obtained from early pregnant woman and examined with ELISA for anti-HCMV antibody IgG and IgM. After artificial abortion,chorionic villus and decidua were also examined with polymerase chain reaction (PCR) for HCMV-DNA. When the results of PCR were positive, pathological changes of these chorionic villus and decidua were analyzed.
RESULTSThe results showed that only 10 samples were PCR positive while IgG and/or IgM antibody to HCMV was positive. After infection with HCMV, different changes occurred in chorionic villus and decidual trophoblastic cells placental villus were hyperplasic and decidua cells degenerated and necrotized followed by lymphocytes infiltration.
CONCLUSIONThese pathological changes may be one of pathogenic factors of HCMV.

OBJECTIVETo investigate the therapeutic effects of hemin, an inducer of heme oxygenase, in a rat model of gestational hypertension and explore the possible mechanism.
METHODSEighteen pregnant SD rats at day 12 of gestation were randomized equally into gestational hypertension model group, hemin treatment group, and normal pregnancy (control) group. In the former two groups, the rats were subjected to daily nitro-L-arginine methyl ester (L-NAME, 80 mg/kg) gavage since gestational day 14 for 7 consecutive days to induce gestational hypertension; saline was administered in the same manner in the control rats. The rats in hemin group received daily intraperitoneal injection of hemin (30 mg/kg) starting from gestational day 16. HO activity and carboxyhemoglobin (COHb) level in rat placental tissue were detected with spectrophotometric method, and soluble vascular endothelial growth factor receptor-1 (sFlt-1) and vascular endothelial growth factor (VEGF) level in the placental tissue homogenate supernatant were detected using ELSIA.
RESULTSAt gestational day 20, the blood pressure and 24-h urinary protein were significantly higher in the model group than in the other two groups (P<0.05), and were higher in hemin group than in the control group (P<0.05); HO activity and COHb content in the placenta tissue were the lowest in the model group (P<0.05), and was lower in hemin group than in the control group (P<0.05). The level of sFlt-1 was significantly higher and VEGF level significantly lower in the model group than in the other two groups (P<0.05); sFlt-1 level remained higher and VEGF lower in hemin group than in the control group (P<0.05).
CONCLUSIONHemin can reduce blood pressure and urinary protein in rats with gestational hypertension possibly by up-regulating HO activity, enhancing carbon monoxide production, reducing sFlt-1 and increasing VEGF in the placental tissue.

OBJECTIVETo explore the significance of Lens culinaris-reactive alpha-Fetoprotein (AFP-L3) detection in primary hepatocellular carcinoma.
METHODSAFP-L3 was isolated by using microspin column coupled with lens culinaris agglutinin (LCA), AFP and AFP-L3 were detected with chemiluminescent immunoassay, the proportion of AFP L3 levels were calculated, and the relationship between the elevated AFP-L3 (%) levels and benign and malignant liver disease was analyzed.
RESULTSThere were significant differences in positive rate between the patients of HCC, suspected HCC and other liver disease (81.80%, 73.68%, 11.80%, respectively, P < 0.05). Among the undetermined HCC (suspected HCC, liver disease) patients, 12 out of 21 cases of AFP-13 positive were diagnosed to be HCC within 6 months, and 6 of them were diagnosed to be the single small HCC at the early stage through B-Ultrasonic Diagnosis or CT. Among 62 cases of AFP-L3 negative, 3 cases were diagnosed to be HCC within 6 months and the risk of occurrence of HCC for AFP-L3 positive increased 11.9 times.
CONCLUSIONAFP-L3 has no correlation with AFP value, and it can be used as an independent HCC diagnosis factor. The detection of AFP-L3 has a significant implication for the identification of benign or malignant liver disease and the early stage predictive diagnosis of HCC while AFP increases.

OBJECTIVETo evaluate the detection method of ELISA and Enhanced Chemiluminescence Immunoassay (ECLIA) in use to determine serum hyaluronate acid (HA), laminin (LN), type IV collagen (IV-C) and type III procollagen (PC III).
METHODS253 patients with chronic hepatitis B were determined the four liver fibrosis serum markers with both the ECLIA and ELISA, and then compared with pathology results separately.
RESULTSBoth the detection results of ELISA and ECLIA can reflect that the patient's liver fibrosis from hepatitis to liver cirrhosis aggravated gradually. Compared with ELISA, the results of ECLIA and pathology have a better correlation.
CONCLUSIONSThe detection of four liver fibrosis serum markers by ECLIA could indicate the better the response of the state of live fibrosis.

OBJECTIVETo investigate whether there is an association between DRD2/ANKK1 Taq IA polymorphism and early infant temperament.
METHODSDRD2/ANKK1 Taq IA polymorphism (rs1800497) was determined using polymerase chain reaction-ligase detection reaction (PCR-LDR) techniques in 149 Chinese Han infants from Changsha City. Their mothers were asked to complete the Early Infant Temperament Questionnaires (EITQ) when the infants were 1 to 4 months old (mean: 2.75 months). There were three genotypes found in these infants: C/C, T/T and C/T. The subjects were subdivided into T-carrier (CT, TT) and non-T-carrier (CC) groups for statistical analysis.
RESULTSThere were no differences in the temperament style distribution between the T-carrier and non-T carrier groups. There were also no statistically significant differences between the two groups in the score of the nine temperament dimensions.
CONCLUSIONSDRD2/ANKK1 Taq IA polymorphism is not associated with early infant temperament.
