Objective To explore the related factors to influence the curative effect of focused ultrasound treatment for non neoplastic epithelial disorders of vulva. Methods A total of 382 patients with non neoplastic epithelial disorders of vulva were included in this study and treated by focused ultrasound. During and after the treatment, the symptoms and physical signs of the subjects were observed, and the efficacy was evaluated. We analyzed the relation between pathologic type, age, course, area, or itch degree and curative effect. Results Symptoms of all patients were relieved, and appearance and color of the vulva became normal after the ultrasound treatment, with a total effective rate of 99.74%. The cure ratios of patients with different pathologic types, ages, courses, areas, and itch degrees were significantly different (χ2=9.58, P<0.01; χ2=22.385, P<0.01; χ2=32.260, P<0.01; χ2=57.99,P<0.01; χ2=42.13,P<0.01, respectively). Conclusion Focused ultrasound treatment is safe and effective for the nonneoplastic epithelial disorders of the vulva and the efficacy is associated with the pathologic type, age, course, area, and itch degree.

Objective To observe therapeutic effects of HuGanJieXian decoction on rats hepatic fibrosis induced by tetrachloride. Methods Rat models of hepatic fibrosis were constructed by intraperitoneal injection of tetrachloride.HuGanJieXian decoction composed of low, middle, and high dose curcumin were given to these rats respectively at the same time. Sho-saiko-to compound treatment group and Fufangbiejiarangan Tablets treatment group were made as positive control groups. After twelve weeks, all rats were executed. Serum samples were kept for measuring serum levels of PC-Ⅲ, LN, and HA. Left livers were extirpated for pathologic examination including H.E and Masson stainings. Grade of hepatic fibrosis were evaluated according to SSS system. The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) of supematant centrifugated from hepatic tissue homogenate were detected. Results Serum levels of PC-Ⅲ, LN, and HA were depressed obviously in decoction groups compared with those of fibrotic group (P<0.05) , especially in the low-dose curcumin group.HuGanJieXian Decoction could increase the level of SOD and decrease the level of MDA (P<0.05) , especially in the low-dose curcumin group. Staining of H. E and Masson showed that degrees of hepatic fibrosis in decoction groups were improved obviously compared with that of the fibrotic group. Conclusion HuGanJieXian Decoction can improve rat hepatic fibrosis, the mechanism of this effect may be associated with protecting hepatic cell membrane and anti- peroxidative damage.

Nine short tandem repeat (STR) markers (D3S1358, VWA, FGA, THO1, TPOX, CSFIPO, D5S818, D13S317, and D7S820) and a sex-identification marker (Amelogenin locus) were amplified with multiplex PCR and were genotyped with a four-color fluorescence method in samples from 174 unrelated Han individuals in North China. The allele frequencies, genotype frequencies, heterozygosity, probability of discrimination powers, probability of paternity exclusion and Hardy-Weinberg equilibrium expectations were determined. The results demonstrated that the genotypes at all these STR loci in Han population conform to Hardy-Weinberg equilibrium expectations. The combined discrimination power (DP) was 1.05 x 10(-10) within nine STR loci analyzed and the probability of paternity exclusion (EPP) was 0.9998. The results indicate that these nine STR loci and the Amelogenin locus are useful markers for human identification, paternity and maternity testing and sex determination in forensic sciences.

ObjectiveTo investigate the effect of NGF on apoptosis of HSC in vitro and explore the possible mechanism.MethodsHSC was incubated with different concentrations of NGF.HSC apoptosis was identified by FCM.The expressions of apoptosis-regulating proteins Caspase-3,p53 and Bcl-2 of HSC after apoptosis induced by NGF were examined by immunohistochemical staining.Expressions of NGF and p75NTR were detected by immunofluorescence.ResultsApoptosis index of HSC was higher than that of control group [(22.36±9.51)％ vs (5.88±1.36)％] after treated with NGF (100 ng/ml) (P＜0.05).After incubating with 100 ng/ml NGF for 24 h,the positive expression rates of p53 and Caspase-3 of HSC increased significantly than those of control group [(78.41±4.00)％ vs (34.96±3.84)％,(39.26±1.57)％ vs (9.27±1.01)％,P ＜0.05].The positive expression rate of Bcl-2 protein of HSC significantly decreased compared with that of control group (18.12±1.38)％ vs (91.53±2.98)％ (P＜0.05).When HSC was stimulated with 100 ng/ml NGF for 24 h,the average optical density of NGF increased significantly than control group (6.53±1.40 vs 1.77±0.17) (P＜0.05),while the expression of p75NTR was not significantly changed (3.52±0.36 vs 4.24±0.38) (P＞0.05).ConclusionsThe mechanism of NGF to induce HSC apoptosis may be associated with the up-regulating expression of Caspase3,P53 and down-regulating expression of Bcl-2 on HSC.NGF could be used as an initiating factor and effect factor to increase the expression of NGF on HSC,but it had no significant effect on p75NTR expression.

Objective To discuss the risk in duo paternity testing. Methods 22 fictitious duo families formed by 22 pairs of unrelated individuals having one or zero inconsistent locus were selected after detected by GoldeneyeTM 20A Kit. The 22 fictitious duo families were further tested with STRtyper-10G kit and/or AGCU 21+1 STR kit until there were more than 3 inconsistent loci and the cumulative paternity index(CPI) value was less than 0.0001. According to the three excluding rules, ① number of inconsistent loci>3; ② CPI ≤ 0.0001; ③ accord with both ① and ② , using multiple STR systems, such as 19 STR loci, 26 STR loci, 39 STR loci and 46 STR loci to test and discuss whether there is difference among the excluding result of unrelated individual. Results Among those 22 fictitious duo families, using three excluding rules, None was excluded by 19 STR loci, and all was excluded by 39 STR loci. Conclusion Duo paternity tests may get a wrong result using only 19 loci system. To reduce the error risk 39 STR-loci systems would be suggested.

To obtain an initial overview of gene diversity and expression pattern in porcine thymus, 11,712 ESTs (Expressed Sequence Tags) from 100-day-old porcine thymus (FTY) were sequenced and 7,071 cleaned ESTs were used for gene expression analysis. Clustered by the PHRAP program, 959 contigs and 3,074 singlets were obtained. Blast search showed that 806 contigs and 1,669 singlets (totally 5,442 ESTs) had homologues in GenBank and 1,629 ESTs were novel. According to the Gene Ontology classification, 36.99% ESTs were cataloged into the gene expression group, indicating that although the functional gene (18.78% in defense group) of thymus is expressed in a certain degree, the 100-day-old porcine thymus still exists in a developmental stage. Comparative analysis showed that the gene expression pattern of the 100-day-old porcine thymus is similar to that of the human infant thymus.
