ABSTRACT

Objective To understand the characteristic of sexual behavior and their associated factors among male and female partners of men who have sex with men in Anhui province. Methods Cross-sectional studies were conducted among MSM in Hefei, Wuhu and Liuan in Anhui province. MSM were recruited through “snowball sampling” and “internet-based recruiting”, and eligible participant received an anonymous survey. Multivariate Logistic regression analysis model was used to identify risk factors associated with having sex with women in the last 6 months among MSM. Results Of the 1 200 MSM interviewed, 78.3% had anal sex with men, and 20.9% had vaginal intercourse with women, and 16.5% had sexual intercourse with both men and women in the past 6 months. Less MSM reported using condom every time with women (29.9%) in the past 6 months than with men (53.0%), and less reported using condom with women (52.2%) during the last sexual intercourse than with men(79.6%) (all P<0.05). The results of mutivariate Logistic regression analysis showed that MSM who were married(including currently married/cohabitating/divorced/widowed), lived more than 2 years in the surveyed city, and had commercial sex with men were more likely to have sex with women. Conclusions There was a high proportion of bisexual behavior and low rate of condom use among MSM. It should strengthen the sexual health education, risk perception education and behavioral intervention among MSM.

ABSTRACT

OBJECTIVE@#To investigate the effects of Radix Angelicae Sinensis (RASI) and hydrocortisone combination on the murine asthma model and the mechanism.@*METHODS@#BALB/c mice were randomly divided into control group, blood stasis model group, asthma model group, HSS group, RASI group and RASI+HSS group (=12). Ovalbumin (OVA) was used to replicate mice asthma model and hydrocortisone sodium succinate (HSS) to copy blood stasis model. Effects of RASI, HSS and their combination on hemorheology, anti-asthma (asthmatic behaviors, lung function, lung index and water content in lung tissue) were observed. and anti-asthma mechanisms The expression of relative cytokines, high-mobility group box 1 (HMGB1), toll-like receptor 4 (TLR4) and nuclear factor-κB (NF-κB) was detected by ELISA and immunohistochemistry respectively.@*RESULTS@#Eight g/kg RASI, 0.05 g/kg HSS and their combination could significantly relieve asthma behavioral indicators, improve lung function, reduce lung index and water content in lung tissue, decrease the levels of TNF-α, IL-1β and IL-6 in broncho-alveolar lavage fluid (BALF), and inhibit the high expression of HMGB1, TLR4 and NF-κB in lung tissue. The improvement of lung function and the decrease in level of relative cytokines (TNF-α、IL-1βIL-6) were better in RASI+HSS group than those in RASI group and HSS group, and the inhibition of protein expression of TLR4 and NF-κB was also too. Combined administration of RASI and hydrocortisone could decrease serum thromboxane B2 (TXB2) content and blood viscosity, which were increased induced by hydrocortisone.@*CONCLUSIONS@#Combined administration of RASI and hydrocortisone have obvious anti-asthma effects and one of the mechanisms is to inhibit protein synthetization of HMGB1, TLR4 and NF-κB.The combined administration of RASI and hydrocortisone has stronger improvement of lung function than that of RASI and hydrocortisone alone, and it may be related to the inhibition of TLR4 and NF-κB synthetization. The combined administration of RASI can alleviate abnormal changes of hemorheology induced by hydrocortisone in treatment of asthma.

ABSTRACT

Objective To lay the foundation for studying the possible pathogenesis of epilepsy and the anti-epileptic mechanism of Banxia Baizhu Tianma Decoction through the bioinformatic analysis of target gene prediction and signal pathway of miRNA-146a-5p in hippocampus of epileptic rats. Methods Lithium-pilocarpine was used to induce seizures in rat models. The experiment rats were randomly divided into normal control group, model group, Banxia Baizhu Tianma Decoction group, with 20 rats in each group. The method of miRNA expression profiling was used to observe the miRNA differential expression of hippocampus neuron cell of rats. The expression level of miRNA-146a-5p was detected by real-time quantitative PCR. MiRDB was used for target gene prediction of miRNA-146a-5p, and miRTarBase and DAVID were used for enrichment analysis on the GO function and KEGG signaling pathway. Results The attack times and grades of the rats in Banxia Baizhu Tianma Decoction group were significantly lower than those in the model group from behavioral observation. MiRNA microarray analysis showed that the expression level of miRNA-146a-5p in model group was 2.107 times normal control group (P<0.05), and the expression level decreased to 1.377 times after treatment with Banxia Baizhu Tianma Decoction (P<0.05). The results of RT-PCR was consistent with that of miRNA microarray, with statistical significance (P<0.05). MiRNA-146a-5p target gene prediction results had 140 target genes by GO, and there were 14 annotation information of biological process (P<0.05), 9 annotation information of cellular component (P<0.05), 11 annotation information of molecular function (P<0.05). Enrichment analysis of KEGG biological pathway showed that 140 target genes of miRNA-146a-5p were enriched in EB virus infection signal pathway and thyroid hormone signaling pathway (P<0.05). Conclusion miRNA-146a-5p is closely related to the inflammatory reaction after epilepsy, and Banxia Baizhu Tianma Decoction can control epilepsy possibly by controlling the inflammatory reaction after epilepsy.

ABSTRACT

This study was conducted to investigate the wild and cultivated resource situation of Rheum tanguticum in main production area of China, estimate its reserves, and put forward the feasible approach for the sustainable utilization of R. tanguticum. On the basis of the literature data about R. tanguticum, conbined with interview, investigation and sampling investigation, the total reserve of resources is estimated using the route-quadrat method and the vegetation and soil-type map area method proposed by our research group. The results indicate that there is no obvious change between the present distribution ranges of the wild R. tanguticum and its historical records, but its population density has changed clearly. The reserve of the wild R. tanguticum has seriously declined in lots of place, even faced the exhaustion in some regions. According to the investigation, the resource reserve of the wild R. tanguticum is no more than 5 000 t, and the cultivated is about 1 607 t. The resource reserve of the wild R. tanguticum is nearly depleted, and this suggests that the wild R. tanguticum should be enrolled in the protection plant list, and the cultivated will become the main resource of Rhubarb in the future. So it is extremely neccessary to collect and protect the germplasm resource of R. tanguticum, establish the germplasm nursery and repository, and conduct breeding research on those bases.

ABSTRACT

Rhei Rhizoma is a Chinese medicine with multiple botanical origins. There is a problem to identify it with conventional methods. To compare the characteristics of chloroplast matK gene sequences of different Rheum species and authenticate inspected species, the matK gene sequences of different species from different origins were amplified, cloned, and sequenced. Genomic DNA of Rheum plants was extracted using modified DNA extracted Kit and matK gene sequences were analyzed by ContingExpress, DNAman and MEGA5.0. The length of matK gene sequences of Rheum palmatum, R. tanguticum and R. officinale were 1 518 bp containing 57 variable loci. According to the mutation sites, R. palmatum, R. tanguticum and R. officinale were divided into different genotypes separately. Based on the established method according to the loci 587, 707, 838, we successfully identified the genuine Rheum species from its adulterants.

ABSTRACT

This study is to reveal the correlation between CNVs of HMGR, SQS1, beta-AS gene and genuineness of liquorice. Real-time PCR was used to detect the copy number of HMGR, SQS1, beta-AS gene of liquorice. According to the results, the range of the copy number variation of HMGR gene was between 1 and 3, the copy number of SQS1 gene was 1 or 2, and the copy number of beta-AS gene was only 1. On the basis of the copy number of HMGR, SQS1 and beta-AS gene, there were five groups, type A (2 + 1 + 1), type B (1 + 1 + 1), type C (3 + 2 + 1), type D (2 + 2 + 1) and type E (3 + 1 + 1). There were two types, type A and type B, in Hangjinqi of Inner Mongolia, and the ratio of A to B was 1:1.3. There were also two types, type A and type B, in Chifeng of Inner Mongolia, and the ratio of A to B was 3:1. There were four types, type A, type B, type C and type D, in Yanchi of Ningxia province, and the ratio of A to B was 1:5.1. There were three types, type A, type B and type E, in Minqin of Gansu province, and the ratio of A to B was 2:1. So CNVs mainly existed in the liquorice from Ningxia and Gansu provinces. While the genetic background of liquorice from Hangjinqi of Inner Mongolia was stabilized. The results of the experiment proved that the correlation between CNVs and origins was one of the reasons of genuineness of liquorice.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the feasibility of applying autosomal single nucleotide polymorphisms (SNPs) on parentage testing.</p><p><b>METHODS</b>All SNP genotyping results of HapMap (r27) were downloaded from the website. With self-made computer programs, SNPs were extracted when their minor allele frequency (MAF) were ≥ 0.30 among all of the 11 HapMap populations. Ninety-six SNPs were chosen and integrated into the Illumina Goldengate bead arrays on the condition that no linkage disequilibrium was found between them. Three father-child-mother trios (9 samples in total) were tested with the arrays. Cumulative paternity index (CPI) was then calculated and compared with genotyping results using 15 short tandem repeats (STRs)(Identifiler(TM)).</p><p><b>RESULTS</b>Family 1 was found to have nine SNPs or seven STRs that did not conform to the Mendelian laws, Family 2 had 13 such SNPs or seven STRs, and Family 3 only had one such SNP but no STR. For Family 3, when all of the 96 SNPs were used in combine, the CPI was 1207, which had contrasted with the CPI by the 15 STRs, i.e., 355 869.</p><p><b>CONCLUSION</b>When applied to paternity testing, the paternity exclusion (PE) value for a SNP is usually less than 1/3 of that of a STR. The proportion of SNPs not comforming to the Mendelian laws for the tested SNPs may not be as high as that of inconsistent STRs over all tested STRs. Because of the low mutation rate of a SNP, the CPI will be greatly reduced even if one SNP did not conform to the Mendelian laws. Therefore, highly accurate testing methods are required to reduce artificial errors when applying SNPs for paternity testing.</p>

ABSTRACT

To study the effect of alpha1-acid glycoprotein 1 (ORM1) polymorphism on the concentration of free nortriptyline in serum, genotyping analysis was employed in ORM1 by sequencing. Eighteen unrelated male adults were chosen and given a single dose of 25 mg nortriptyline orally, then the blood samples were taken at 0, 1, 2, 3, 4, 6, 8, 12, 24, 32, 48, 72, 96 and 168 hours after drug administration. Nortriptyline and 10-OH-nortriptyline in serum and ultrafiltrate were detected for the total and free concentration by using HPLC-MS/MS. Pharmacokinetic parameters were compared among different ORM1 genotypes. No significant differences were shown in the pharmacokinetic parameters of total nortriptyline and 10-OH-nortriptyline. The mean AUC(0-infinity) of free nortritpyline in ORM1 * F/ * F1 subjects was significantly higher than that in ORM1 * F1/ * S and ORM1 * S/ * S subjects [(119.1 +/- 74.4) ng x mL(-1) x h vs (51.4 +/- 23.2) ng x mL(-1) x h and (42.4 +/- 11.6) ng x mL(-1) x h]. The percentage of protein binding in subjects with ORM1 * F1/ * F1 genotype at 2, 3, 4, 6, 8 and 12 h after administration was slightly lower than in those with ORM1 * F1/ * S and ORM1 * S/ * S genotypes while the distinct difference was shown at 4 h (P < 0.05). Different ORM1 genotypes might affect the protein binding percentage and the concentration of serum free nortriptyline. The ability binding to the drug was higher in subjects with ORM1 * S/ * S genotype than in those with other two genotypes, so as to cause the lower concentration of free nortriptyline.
