To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

OBJECTIVETo investigate the association of single nucleotide polymorphisms(SNP) of FOXP3 gene with susceptibility to systematic lupus erythematosus (SLE) in Chinese Zhuang population.

METHODSAuthor analyzed the -2383 C/T and -3281 C/A two SNPs of the FOXP3 gene promoter in 120 patients with SLE and 160 age and sex matched controls in a Chinese Zhuang population, using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) strategy and DNA sequencing.

RESULTSThe distribution of the FOXP3 gene -3281 C/A polymorphism was not different between the two groups. However, the FOXP3 gene -2383 C/T polymorphism was significantly different (P<0.05) between the two groups. The relative risk of suffering from SLE of -2383T allele carriers was 1.715 times of the -2383C allele carriers (OR=1.715, 95%CI: 1.165-2.525). Consistent with the results of the genotyping analyses, the FOXP3 -2383T/-3281A haplotype frequency in patients with SLE was significantly higher than that in controls (P<0.05). The -2383T/-3281A allele was associated with a significantly increased risk of SLE (OR=2.196, 95%CI: 1.165-4.142).

CONCLUSIONThe FOXP3 gene -2383C/T polymorphism is associated with SLE, and the -2383T allele is risk factor for SLE in the population studied.

OBJECTIVETo observe the effect of SHENG MAI ZHUSHEYE on the movement parameters and viability of human sperm in vitro.

METHODSWe collected sperm samples from 33 normal fertile men, divided each into two, and cultured them in vitro with SHENG MAI ZHUSHEYE + Hams-F10 and Hams-F10 alone, respectively. Then we measured the straight line velocity (VSL), curvilinear velocity (VCL), average path velocity (VAP) and the amplitude of lateral head displacement (ALH) of the sperm by computer-aided semen analysis at 0.5, 1, 2, 4, 8 and 12 h. And the sperm viability was detected.

RESULTSVCL was significantly higher at 8 h (P < 0.05) and very significantly higher at 12 h (P < 0.01) in the SHENG MAI ZHUSHEYE + Hams-F10 group than in the Hams-F10 group. VSL, VAP and ALH were significantly increased in the former group at 4, 8 and 12 h as compared with the latter (P < 0.05). The sperm viability was significantly decreased in the Hams-F10 group at 12 h (P < 0.05).

CONCLUSIONSHENG MAI ZHUSHEYE can improve sperm movement parameters and increase sperm viability in vitro.

OBJECTIVETo explore the regulatory effect of arginine on the secretion of hepatic insulin-like growth factor-1 (IGF-I), and the mechanism of enhancing the immune function by arginine.

METHODSWistar rats were randomly divided into normal control (NC), wound control (WC), and wound with arginine (Arg) groups, with 8 rats in each group. The rats in WC and Arg groups were inflicted with soft tissue trauma on the back. The rats in Arg group were fed a diet supplemented with 5% arginine for one week, while those in NC and WC groups were fed with glycine. The serum contents of arginine, ornithine, growth factor (GH), NO and IGF-I were determined 7 days after feeding. T cell proliferation and IGF-I mRNA expression in hepatic tissue were also measured. Meanwhile, the rat hepatocytes were cultured in serum-free medium containing different concentrations of arginine. The supernatant was collected for the determination of IGF-I level.

RESULTS1). There was no obvious difference of the serum level of arginine and ornithine between NC and WC groups (P > 0.05), but the contents of them were obviously higher in the Arg group compared with other two groups (P < 0.01). 2). No difference in the serum GH level was found among all the groups (P > 0.05), but the serum NO content in WC and Arg groups was significantly lower than that in NC group (P < 0.01), and the serum IGF-I content in WC group decreased obviously compared with that in NC group (P < 0.01). 3). The thymocyte proliferation rate in WC group was also markedly lower than that in NC group (P < 0.01), but that in Arg group was improved compared with WC group (P < 0.01). 4). The expression of hepatic IGF-I mRNA: The relative value of IGF-I mRNA was 1.19 +/- 0.06, 1.08 +/- 0.06 and 1.29 +/- 0.06 in NC, WC and Arg, respectively, while the value in WC was lower than that in NC (P < 0.05) group, and that in Arg group was much higher than that in WC group (P < 0.01). 5). The IGF-I level in the supernatant of cultured hepatocytes: When Arg concentration was 0.0750, 0.7500, 7.5000 mmol/L in the culture medium, the IGF-I level in the supernatant of hepatic cell medi-um was obviously higher than that in the medium without arginine (P < 0.01). Although IGF-I level decreased in the culture medium with arginine in the dose of 37.5000 mmol/L, it was still obviously higher than that in the medium without arginine (P < 0.01).

CONCLUSIONArginine could also produce the immune enhancing effect by stimulating hepatic IGF-I secretion.

Monovalent antisera of 3 vaccine strains and 7 representative field isolates were prepared based on the comparison of genetic diversity of the hypervariable region I of S1 gene (HVR I from 3 infectious bronchitis (IB) vaccine strains (H120, Ma5 and 4/91) ,one reference strain M41 and 26 IB field isolates. These 30 strains were classified in 7 different genotypes, respectively. Virus-neutralizing test on tracheal organ cultures (TOC) with chicken embryo were used to evaluate relatedness values of the antigenicity based on the antibody titer, to analyze the antigenic relationships between the isolates and vaccine strains, as well as to determine the serotypes of 26 IB viruses isolated from the field in Guangxi between 1985 and 2008. The results showed 30 strains were classified into 7 distinct serotypes and there were two predominant serotypes within the 26 isolates, serotypes 1 (totally 13 isolates) and serotype 2 (totally 5 isolates), respectively. In addition, there were some differences observed between the results of serotyping and the genotyping (including the S1, N, M and 3'UTR). The results of the study demonstrated that there were different predominant serotypes and multiple serotypes of IBV circulated in Guangxi in recent years, antigenic variation existed between Guangxi field isolates and vaccine strains.

OBJECTIVETo investigate the association of the single nucleotide polymorphisms of interleukin-18 (IL-18) gene with the susceptibility to systematic lupus erythematosus (SLE) in a Chinese Zhuang population.

METHODSTwo single nucleotide polymorphisms of the IL-18 gene promoter were analyzed, namely -137G/C and -607C/A, in 115 patients with SLE and 160 age and sex-matched controls in a Chinese Zhuang population, using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) strategy and DNA sequencing.

RESULTSThe IL-18 gene -607C/A polymorphism was significantly different between the SLE and control group (P < 0.05). The relative risk of SLE for -607C allele carrier was 1.619 times of the -607A allele carriers (OR=1.619, 95%CI: 1.150-2.281). Consistent with the results of the genotyping analyses, IL-18 -137G/-607C allele frequencies in patients with SLE was significant higher than that in controls (P < 0.05). The -137G/-607C allele was associated with a significantly increased risk of SLE (OR=1.484, 95%CI: 1.056-2.087). However, there was no difference of the distributions of the -137G/C polymorphism of the IL-18 gene between the SLE and control groups.

CONCLUSIONIL-18 gene -607C/A polymorphism was associated with SLE, the -607C allele may be a risk factor for SLE.

This article reported the clinical manifestations, steroid profiles and adrenal ultrasound findings in two unrelated Chinese girls with lipoid congenital adrenal hyperplasia (LCAH). Direct DNA sequencing and restriction fragment length polymorphism (RFLP) analysis were used to identify the mutations of steroidogenic acute regulatory protein (StAR) gene. The two patients with 46,XX karyotype, presented hyperpigmentation, growth retardation, and hyponatremia. Steroid profiles analysis revealed elevated plasma adrenocorticotrophic hormone levels, decreased or normal serum cortisol levels and low levels of androgens. Ultrasound examinations revealed that enlarged adrenals in patient 1 and normal adrenals in patient 2. Direct DNA sequencing of StAR gene showed a reported homozygous for c.772C>T(p.Q258X) in patient 1. Compound heterozygous for c.367G>A(p.E123K) and IVS4+2T>A (both novel mutations) were found in patient 2, inherited from her mother and father respectively. The amino acid of mutant position of the novel p.E123K was highly conserved in ten different species and was predicted to have impacts on the structure and function of StAR protein by the PolyPhen-2 prediction software. RFLP analysis revealed three bands (670, 423 and 247 bp) in patient 2 and her father and two bands (423 and 247 bp) in her mother and 50 controls. It is concluded that LCAH should be considered in girls with early onset of adrenal insufficiency and that steroid profiles, karyotype analysis, adrenal ultrasound and StAR gene analysis may be helpful for the definite diagnosis of LCAH.
