Objective To find out the physical state of the human papillomavirus ( HPV) genome in hepatoma cell line HepG2 cells and the regulation of HPV late capsid protein 1 ( L1) expression and to explore the nature of the cytoryctes in HepG2 cells.Methods E2 and E6 in HPV18 were detected by PCR to evaluate the physical state of HPV18 genome .HepG2 L1 expression was detected by ELISA , light microscropy and electron microscrope immu-nohistochemistry assays , Western blot assay using HPV L 1 mice monoclonal antibody .L1 mRNA in HepG2 cells was detected by reverse transcriptional PCR ( RT-PCR) .Results PCR assay displayed that HPV DNA was inte-grated with HepG2 genome.ELISA assay showed that HPV L1 was present in lysate of HepG2 cells.Light micros-cropy demonstrated strong positive reaction in HepG2 cells.In microscopy, in the cytoplasm of partial HepG2 cells, there were lumpish cytorrhyctes materials which consists of very small and uniform particles and these parti -cles were marked by HPV L1 antibody labeled by colloidal gold .Western blot analysis showed a band at 56 ku dis-trict and it was L1 specific strap which demonstrated HPV 18 L1 was present in HepG2 cells.RT-PCR assay demon-strated the presence of L1 mRNA in HepG2 cells.Conclusions HepG2 cells are HPV18-positive HPV DNA ge-nome is integrated with HepG2 cells.HepG2 cells can express L1.The cytorrhyctes in HepG2 cells are composed of HPV18 L1 indicating that L1 can be expressed in HepG2.

Objective To determine the incidence, clinical manifestation and risk factors of immune reconstitution inflammatory syndromes (IRIS) in highly active antirctroviral therapy (HAART) for HIV/AIDS patients. Methods Two hundred and twelve HIV/AIDS patients received HAART, and were followed up for 6 months. The incidence time and disease spectrum of IRIS were observed. Multiple logistic regression analysis was performed to identify the risk factors for IRIS. Results Among 212 patients, there were 59 (27.8%) experienced an IRIS event during the first 6 months of HAART, 2 of which died (2/59,3.39% ). Median time of IRIS onset was 21 days form HAART initiation. The disease spectrum included tuberculosis, herpes virus infections, pneumocystis jirovecii pneumonia, cryptococcal meningitis and penicillium marneffei infection. Risk factors of IRIS included baseline infections ( OR = 1. 655, P =0.010),fever during HAART ( OR = 2. 344, P= 0.006), and baseline CD4 + count ( OR = 1. 556, P = 0. 034).Conclusions IRIS usually occurred within the first month from HAART initiation, and tuberculosis and herpes virus infection are most common. The occurrence of IRIS is associated with the antigens burden and the decreased baseline CD4 + count.

OBJECTIVETo investigate effects of zearalenone (ZEA) on the proliferation of SK-N-SH human neuroblastoma cells in vitro and its possible mechanism.
METHODSSK-N-SH cells were cultured in estrogen-free improved minimum essential medium and divided into 5 groups based on different treatments: group 1, without treatment; group 2, treated with 17beta-estradiol (E(2)); group 3, treated with ZEA; group 4, treated with both E(2) and ICI 182780; group 5, treated with both ZEA and ICI 182780. Absorbance value (AV) was determined at the time point of 0, 24, 48 and 72 hours, and DNA proliferation index (PI) at 72 hours. Flow cytometer, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) were employed to monitor cell apoptosis.
RESULTSAt 24, 48 and 72 hours, the AV of group 3 were 1.39, 1.32, and 1.22 times to those of group 1, respectively. PI in group 3 was 1.43 times of that in group 1 at 72 hours. The results of group 2 were similar to those in group 3. At the same time, the growth of cells was inhibited by ICI 182780 despite the presence of E(2) and ZEA. Apoptosis cells were abundant in group 1 and ICI 182780 groups, but little in E(2) and ZEA groups.
CONCLUSIONZEA might promote the proliferation of SK-N-SH cells to a level similar to that of E(2), which might probably be brought about via estrogen receptor pathways and depressing apoptosis.

Objective: To investigate the influence of esculentoside A(EsA) on production of IL-1 and TNF by rabbit synovial cells induced by LPS. Methods: levels of IL-1 and TNF in the supernatant of rabbit synovial cell were determined by examining proliferation of thymic cells and by bioassay L929 cells as target cells, respectively. Results: EsA in 5-40 μg/ml could significantly inhibit the production of IL-1 and TNF from rabbit synovial cells induced by LPS. Conclusion: EsA can inhibit the production of IL-1 and TNF from synovial cells. It suggests that EsA may play a role in improving the rheumatoid arthritis.

A sesquiterpene synthase (AsSS4) full-length open reading frame (ORF) cDNA was cloned from wounded stems of Aquilaria sinensis by RT-PCR method. The result showed that the ORF of AsSS4 was 1,698 bp encoding 565 amino acids. Prokaryotic expression vector pET28a-AsSS4 was constructed and transformed into E. coli BL21 (DE3) pLysS. Recombinant AsSS4 protein was obtained after induction by IPTG and SDS-PAGE analysis with a MW of 64 kD. Enzymatic reactions using farnesyl pyrophosphate showed that recombinant AsSS4 protein purified by Ni-agarose gel yielded five sesquiterpene compounds, cyclohexane, 1-ethenyl-1-methyl-2, 4-bis(1-methylethenyl)-, β-elemene, α-guaiene, α-caryophyllene and δ-guaiene. This paper reported the first cloning and functional characterization of AsSS4 gene from A. sinensis, which will establish a foundation for future studies on the molecular mechanisms of wound-induce agarwood formation in A. sinensis

Acta Academiae Medicinae Sinicae 2004;26(4):423-425
OBJECTIVETo study the effect of repeated firings on color of porcelain-fused-to-titanium restorations.
METHODSTwenty standard porcelain-fused-to-titanium specimens were made with Dentsply DETREY TiBond C3 and Dentaurum rematitan Til. Then they were fired 1, 2, 4, 7, and 10 times. Color measurement was done after each firing.
RESULTMost of the color parameters had no significant difference after firing except for a* and Hab. All the color difference among groups were smaller than 1.0 (deltaE < 1.0).
CONCLUSIONRepeated firings will not affect the color stability of porcelain-fused-to-titanium restorations.
