italic>Alangium chinense is a commonly used medicinal plant of Alangiaceae Alangium, one of the characteristic Miao medicines in Guizhou. The genus is strongly differentiated and has complex morphological variation, with significant differences in active ingredients and potency among herbs. In this paper, we sequenced the chloroplast genomes of Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib using Illumina high-throughput sequencing technology. The genomes of Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib chloroplasts were sequenced, their assembly annotation and structural characterization were completed, and the genomes of the congeners Alangium chinense and Alangium alpinum were downloaded from NCBI for comparative analysis. Finally, the phylogenetic tree was constructed by selecting published species with close affinity to Alangium chinense family from NCBI. The results were as follows: Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib chloroplast genomes were 156 670, 156 672 and 156 871 bp in length, with a typical four-segment structure, all containing one long single copy region (LSC), one short single copy region (SSC) and two inverted repeat regions (IRa and IRb). All of them were annotated to 133 genes, including 88 protein-coding genes, 37 tRNA genes and 8 rRNA genes. Three types of long repeat sequences and SSR loci, forward repeats, palindrome repeats and reverse repeats, were found in all chloroplast genomes. Comparative genomic analysis showed that there was diversity in the boundary transition regions of the five species, no rearrangements or inversions were found in the chloroplast genome, and there were significant differences in the coding regions of ndhA, ycf1, rpl16, ycf2, and petD genes, which provided new loci for molecular identification of Patagonia. In the phylogenetic analysis, Alangium kurzii var. kurzii clustered as a single species, and Alangium chinense subsp. Pauciflorum and Alangium chinense subsp. Strigosum clustered as a single species, with a support rate of 93 and close affinity, indicating that the phylogenetic tree can be used for the species identification. This paper can provide a basis for the taxonomic identification of Alangium, ensure the safety of clinical use of anise herbs and regulate the market of Alangium chinense herbs.

Human immunodeficiency virus(HIV) infection may result in serious impairment of the immune system in HIV-posi-tive patients. Both HIV productions and highly active antiretrovi-ral therapy (HAART) drugs can cause neuropathy, including the HIV associated neurocognitive disorders (HAND) and the peripheral neuropathy. Several animal models have been devel-oped in an attempt to study the mechanisms of HIV relative neu-ropathies. This review focuses on researching HIV-1 associated neuropathies by application of HIV-1 animal models.

OBJECTIVETo study the effect of silicon dioxide (SiO(2)) on the activation of nuclear factor-kappaB (NF-kappaB) in THP-1 cell line.

METHODSTHP-1 cells were incubated with a series of doses of SiO(2) (0, 100, 200 micro g/ml). The location of NF-kappaB p65 subunit (NF-kappaB/p65) in THP-1 cells was detected by immunofluorescence and laser scanning confocal microscope (LSCM). The expression of NF-kappaB/p65 in nuclei was measured by Western blot analysis.

RESULTSThe majority of fluorescein isothiocyanate (FITC)-labelled NF-kappaB/p65 located in the nuclei 30 min after stimulation by 100 micro g/ml SiO(2), whereas the FITC-labelled NF-kappaB/p65 were mainly seen in the plasma of normal control cells. The expression of NF-kappaB/p65 in THP-1 nuclear protein was low in control group (0 micro g/ml SiO(2)) while it increased after stimulation by 100 micro g/ml SiO(2) and 200 micro g/ml SiO(2) for 15 min and 30 min. The level of NF-kappaB/p65 was comparatively increased with the increasing of doses and time. Lipopolysaccharides (LPS), an activator of NF-kappaB, had similar effect as SiO(2) on the activation of NF-kappaB/p65 in THP-1 cells.

CONCLUSIONSiO(2) could activate and internalize NF-kappaB in the THP-1 cell line.

OBJECTIVETo analyze the gene mutation in two pedigrees of inherited coagulation factor VII (FVII) deficiency, and investigate the relationship between the genotype and phenotype.

METHODThe coagulation function and coagulation factors activity of probands were detected for phenotype diagnosis, all exons and junctions of FVII gene from the family members' genomic DNA were amplified using polymerase chain reaction (PCR), and detected the gene mutation by direct sequencing. Mutations were confirmed by reverse sequencing.

RESULTThe prothrombin time (PT) of proband 1 was 265.2 s, FVII:C was 22% and the PT of proband 2 was > 120 s, FVII:C was 1%. Homozygous 17844G→A mutation in No. 8 exon of FVII gene was identified in the proband 1 resulting in Gly343Ser, and heterozygosity for the same mutations were confirmed in his parents and a sister. The proband 2 was compound heterozygous, one mutation was the same as the proband 1 but was a heterozygosity that can also found in his mother and brother; the other heterozygosity mutation was located on No. 8 exon 18055G→A that resulted in Gln413Arg which was inherited from his father.

CONCLUSIONNo. 8 exon of FVII gene encodes catalytic domain. Mutation found in those domain could change the FVII catalytic domain spatial structure, affected FVII function and stability, and the sufferer of homozygote and compound heterozygous may have clinical bleeding tendency. Almost no clinical findings in simple heterozygotes, however, a few of heterozygotes could have a tendency of bleeding because of genetic polymorphism which would reduce the FVII:C.

OBJECTIVETo assess the recovery of the reproductive endocrine function in rats following orthotopic transplantation of fetal ovarian allograft.

METHODSNinety female SD rats (50-60 days old) were randomized into graft recipient group (n=50), positive control group (n=20), and negative control group (n=20) to receive orthotopic transplantation of fetal (17-19 gestational days) ovaries following bilateral oophorectomy, sham abdominal surgery, and bilateral oophorectomy, respectively. At 45 days after the surgeries, serum estradiol and progesterone levels were measured and the ovaries were removed for evaluation of the ovarian volume and follicle development.

RESULTSOn day 45 after the operations, the estradiol or progesterone levels showed no significant difference between the recipient group and positive control group (P>0.05), but both were significantly lowered in the negative control group (P<0.05). The ovarian volume was comparable between the recipient group and positive control group (P>0.05), and optical microscopy showed follicles in different stages of development and formation of corpus luteum in the ovaries in both groups.

CONCLUSIONFetal rat ovary allografts can develop into functional ovaries capable of ovulation to restore the reproductive endocrine function of recipient female rats.

The phenotypes of the bone marrow cells in various subtypes of myelodysplastic syndromes (MDS) and its clinical implication were explored. The antigen expression of a panel of antigens expressed in marrow cells from 30 patients with subtypes of MDS was assayed by alkaline phosphatase anti-alkaline phosphatase method. The results showed that the expression of myeloid antigens appeared abnormality, CD13 and CD33, found on granulocyte and macrophage precursors, increased, and CD15 decreased. There were no significant changes for monocytic antigen CD14 and lymphoid antigens CD7 and CD10. CD34 was increased in RAEB/RAEB-t and was not increased in RA/RAS patients. CD71, expressed by erythroblast and proliferative cells, was higher in all subtypes of MDS than that in control group. It is suggested that the bone marrow cells from MDS patients showed abnormality of more than two series of immunophenotypes, detection of immunophenotype in MDS cells might be contributed to the diagnosis and predicting prognosis.

OBJECTIVETo explore the effect of occupational stress on ambulatory blood pressure.

METHODS30 male healthy workers from the refrigerator assembly line in Henan province in China were investigated. Psychosocial work conditions were measured by using the Job Demand-control Model, the Effort-reward Imbalance Model questionnaires and Occupational Stress Measurement Scale. Ambulatory blood pressure(ABP) was measured by using mobile ABP monitor. The t test was utilized to analyze the difference of parameters of ABP monitoring between different groups of occupational stress and other variables scores. The stepwise regression analysis was used to analyse the effect of occupational stress factors on parameters of ABP.

RESULTS(1) As to stressors, systolic blood pressure variability (SBPV), mean arterial blood pressure variability (MABPV) and heart rate at 30 minute after work in workers with high role conflict score were significantly higher than those in workers with low score (P < 0.05). Workers with high skill utilization score had significantly lower mean systolic blood pressure (SBP) at 30 minute after work than workers with low score (P < 0.05). Diastolic blood pressure variability (DBPV) and heart rate variability (HRV) in workers with high decision latitude score were significantly higher than those in workers with low score (P < 0.05). Workers with high job psychological demands score had significantly higher SBPV, DBPV and MABPV than workers with low score (P < 0.05). Heart rate-pressure product(RPP) and SBPV in workers with high effort score were significantly higher than those in workers with low score (P < 0.05). Workers with low rewards score had higher mean heart rate and heart rate at 30 minute after work than workers with high score (P < 0.05). (2) For personalities, workers with high work locus of control score had significantly higher mean diastolic blood pressure (DBP) and mean arterial blood pressure (MABP) than workers with low score (P < 0.05). Workers with high patience score had significantly lower mean SBP at 30 minute after work than workers with low score (P < 0.05). Heart rate at 30 minute after work in workers with high organization commitment score was significantly lower than that in workers with low score (P < 0.05). (3) Concerning buffer factors, HRV in workers with high control strategies score were significantly lower than that in workers with low score (P < 0.05). Workers with low supervisor support score had higher RPP and MABPV than workers with high score (P < 0.05). (4) In the multiple stepwise regression, daily life stress affected SBPV (R2 = 0.12) and MABPV (R2 = 0.05), depression was related to DBPV at 30 minute after work (R2 = 0.15) and SBPV (R = 0.03), mental health was predictor of MABPV (R2 = 0.07) and negative affection was predictor of heart rate at 30 minute after work (R2 = 0.24).

CONCLUSIONSOccupational stressors, personality and social support have effect on parameters of ABP. Parameters of ABP monitoring could be used to evaluate occupational stress in the field research.

OBJECTIVETo explore the effect of occupational stress on hypertension.

METHODS498 workers whose accumulative length of service was more than two years were investigated with questionnaire by method of cluster sampling from a thermal power plant in Henan province in China; 446 respondents returned qualified questionnaire including 281 male and 165 female Han People. After the patients with secondary hypertension, diabetes patients, and patients with liver or kidney disease were excluded, 84 workers (58 males and 26 females) were diagnosed as hypertension. The occupational stressors, personalities, buffering factors and occupational strain were measured by using the Job Demand-control Model, the Effort-reward Imbalance Model questionnaires and Occupational Stress Measurement Scale. Main risk factors for the development of hypertension such as heredity, body mass index, high salt diet, alcohol use, smoking habit and lack of physical activity were investigated. 498 whole blood samples were collected from workers in field epidemiologic survey. All of the samples were detected TG, CHO and FPG by common biochemistry methods. Multivariate logistic regression analysis were used to determine the relationship between occupational stressors and prevalence rate of hypertension. The difference of morbidity of hypertension between different stress level subjects was analyzed by chi2 test.

RESULTS(1) Logistic regression analysis of the hypertension by all occupational stressors and risk factors of hypertension indicated that not only some common factors such as parents' hypertensive history, BMI, alcohol use and TG, but also responsibility for person, work locus of control and social support were significantly correlated with elevated risks of hypertension. (2) Logistic regression analysis of the hypertension by main dimensions of effort-reward imbalance model and risk factors of hypertension indicated that parents' hypertensive history, BMI, alcohol use, TG, and effort were significantly correlated with elevated risks of hypertension. Logistic regression analysis indicated the risk of hypertension had an effect on the FRI and effort (OR was 1.71 and 2.43 respectively). (3) For the job strain model, results indicated that parents' hypertensive history, UMI, alcohol use, TG, work locus of control and social support were significantly correlated with elevated risks of hypertension. But the main dimensions of job strain model (job demands and decision latitude) didn't enter regression equation. (4) The difference of prevalence of hypertension between high- and low stress level groups in male was statistically significant (OR = 3.13, P < 0.01), but the case was not the same in female (P > 0.05).

CONCLUSIONSOccupational stress might be risk factor of hypertension; The predictive power of effort-reward imbalance model for the development of hypertension would be larger than that of job strain model.
