OBJECTIVETo establish genetic method in detecting Cryptosporidium parvum and Giardia lamblia which often coinfected with AIDS patients.

METHODSCryptosporidium oocysts and Giardia cysts were isolated and purified from fecal samples of the individuals infected with C. parvum and G. lamblia, respectively. Genomic DNAs were extracted. Two pairs of specific primers were designed or synthesized according to the 18S rRNA gene from C. parvum or the triose phosphate isomerase (tim ) gene from G. lamblia. Polymerase chain reaction(PCR) technique was used to amplify the DNA samples from the oocysts and the cysts, and those from the 6 control samples, including Schitosoma japonicum, Toxoplasma gondii , Entamoeba histolytica, Trichinella spiralis, Trichomonas vaginalis and human blood cells. DNA samples from 30 fecal samples of AIDS patients were detected with the same method.

RESULTSOne fragment of 500 bp was amplified with the primer of C. parvum, and the other one of 683 bp was amplified with the primer of G. lamblia. Twenty pg and 0.4 pg DNA of C. parvum and G. lamblia could be detected separately. The specificity of these two pairs of PCR primers was confirmed by the failure in the amplification of the control DNA samples. Out of 30 cases of AIDS patients, 7 showed C. parvum positive, while non Giardia was detected.

CONCLUSIONGenetic detection method for C. parvum and G. lamblia detection was established which was more sensitive and specific.

OBJECTIVETo study the clinical effects of integrative Chinese and Western medicine in treating chronic urticaria and its impact on peripheral blood content of interleukin-10 (IL-10) and IL-8.

METHODSPatients were assigned to the treatment group and the control group according to their sequence of visiting. They were treated orally with levocetirizine hydrochloride 5 mg once a day, but additional Kangqian Decoction (a self-formulated Chinese herbal preparation consisted of thorowax root 15 g, divaricate saposhnikovia root 9 g, licorice root 15 g, moutan bark 15 g, red sage root 15 g, milkvetch root 30 g, and schisandra fruit 12 g, etc. ) was given to the treatment group one dose per day, for 2 weeks as one therapeutic course. The efficacy was evaluated after two courses of medication, and patients' IL-10 and IL-8 levels in the peripheral blood were determined before and after treatment.

RESULTSThe total effective rate in the treatment group and control group was 93.75% and 56.66% respectively with significance difference between them (P <0.01). After treatment, the level of serum IL-10 was significantly lower while that of IL-8 was significantly higher in the treatment group (2.96 +/- 1.66, 50.17 +/- 32.35) than that in the control group (4.77 +/- 2.99, 29.44 +/- 17.62) respectively (P < 0.01).

CONCLUSIONChronic urticaria was related to the immune unbalance of body. Integrative medicine could adjust immune function to display a quick, potent anti-inflammatory and anti-anaphylactic actions in treating chronic urticaria with less adverse reaction and low recurrent rate.

Objective To preliminary study on the physical properties of HN- 1 modified adriamycin (DOX) nanoparticle system HPD and to prove its transplanted oral squamous cell carcinoma (OSCC)-targeting capability. Methods Firstly, the targeting capability of HN-1 for OSCC cells was verified. PEGylated DOX (PD) nanoparticles were synthesized by self-assembly in aqueous media. HN-1 was then chemically grafted onto the surface of PD nanoparticles to form HPD nanoparticles. The HPD nanoparticles were stored in H2O, PBS and PBS containing 10%serum for different time periods. The sizes and distribution diagrams of nanoparticles were evaluated at 1, 3, 5 and 7 days. The serum levels of DOX mediated by HPD nanoparticles were measured. The stability of HPD nanoparticles in vivo was studied. The tumor bearing mice were prepared by inoculating 2.0 × 106 SCC-25 cells into BALB/C nude mice. Then, mice were randomly divided into four groups (n=2 for each group), normal saline group (control), free DOX group, PD group and HPD nanoparticle group. A dose of 8.0 mg/kg body weight on a DOX basis was injected intravenously though tail vain. The mice were sacrificed at 8 h and 24 h after injection, and the major organs (heart, liver, spleen, lung and kidney) and tumor were excised. The ex vivo DOX fluorescence imaging was obtained using the IVIS. Results HN-1 showed strong capability of targeting OSCC cells. HPD nanoparticles showed an uniform spherical shape and a small size of 150 nm, which also showed strong stability. In the nude mice bearing OSCC tumor, HPD nanoparticles displayed remarkably enhanced tumor-targeting and penetrating efficiency compared with those of PD nanoparticles. Conclusion This study demonstrates that HPD nanoparticles mediated by HN-1 can efficiently target transplanted OSCC, and have potential application for the OSCC-targeting treatment.

OBJECTIVETo investigate the feasibility of serum pharmacology in evaluating the antitumor effect of Chinese medicine (CM) of Fuzheng Guben (supporting the healthy energy and strengthening the body's resistance to pathogens), the effects of Fuzheng Yiliu Decoction (FYD), a typical prescription of Fuzheng Guben, on proliferation and apoptosis of hepatoma cells in vitro were observed by two methods with serum pharmacology and traditional pharmacology, respectively.

METHODSHepG2 cells were treated with FYD-containing serum or crude FYD extract in vitro. The proliferation rate was determined by methyl thiazolyl tetrazolium (MTT) assay. Cell cycle and apoptosis rate was performed by flow cytometry. And the levels of interleukin-2 (IL-2) and tumor necrosis factor α (TNF-α) in FYD-containing serum were detected by radioimmunoassay.

RESULTSFYD-containing serum remarkably inhibited proliferation and induced apoptosis of hepatoma cells at least by promoting the production of IL-2 and TNF-α in vivo. On the contrary, crude FYD extract promoted the proliferation and did not induce cell apoptosis.

CONCLUSIONThe results by serum pharmacology were accordant with those of our previous animal and clinical trials which indicates that serum pharmacology is a reasonable and feasible method for the evaluation of the antitumor effect of herbs of Fuzheng Guben.

Objective To establish a real time PCR assay with a novel fluorescence quencher for identification of mutation of clarithromycin -resistance gene of Helicobacter pylori.Methods Two mutations of 23S rDNA gene in Helicobacter pylori,No.2142 and 2143,were chosen as targets for detection,and then the primers and the probe with a novel fluorescence quencher were designed.The genome DNA of Helicobacter pylori was extracted,and then detected by real time PCR reported here.Meanwhile,the specificity,reproducibility and sensitivity of the assay were evaluated.Finally,the real time PCR described here,the real time PCR based on TaqMan,and a sequencing assay were applied to detect 55 Helicobacter pylori strains isolated from clinical specimens,respectively.The results from three assays were compared with each other in order to further evaluate the applicability of this assay in clinic.Results It indicated that the mutation points related to clarithromycin -resistance,A2142G and A2143G,were identified by real time PCR with a novel fluorescence quencher rapidly and accurately.Moreover the coefficient of variation was less than 5%.The limit of detection was 100 copies/reaction.While this assay was applied directly to detect 55 Helicobacter pylori strains,the results were in accordance with those obtained from a TaqMan real time PCR and a sequencing assay,respectively.Conclusion The real time PCR described here was a simple,reliable and accurate approach and substituted for the TaqMan real time PCR for identification of two mutation points of clarithromycin -resistance,A2142G and A2143G in Helicobacter pylori.Thus,a novel tool for diagnosis of gene mutation was provided and the results might be regarded as a substantial evidence for clinical individual therapy.

BACKGROUNDNumerous studies have shown that reducing the level of tumor necrosis factor-alpha (TNFα) through the use of anti-TNF antibodies or soluble TNF receptor is a safe and efficacious treatment to inflammatory diseases such as rheumatoid arthritis. Therefore, novel approaches to achieve this outcome are desired. The aim of this study was to investigate the characterization of a small molecule inhibitor, Y316, which blocks TNF mRNA upregulation and TNF production by lipopolysaccharides (LPS) stimulated monocytes.

METHODSPeripheral blood mononuclear cells (PBMC) from healthy volunteers were plated in 24-well plates and stimulated with LPS (1 µg/ml), phorbol-12-myristate-13-acetate (PMA) (100 ng/ml), zymosan (10 µg/ml) and Tsst (100 ng/ml). Supernatants were collected after 4-hour culture at 37°C, and quantitative determination of TNFα, interleukin-1β (IL-1β), IL-6, IL-8, IL-10 and IL-2 production in the supernatants was performed by colorimetric enzyme-linked immunosorbent assay (ELISA). Total RNA of PBMC was isolated and cytokine mRNA quantitation was performed by using a RNA level measuring kit (R & D Systems). PBMC were pretreated with Y316 (10 µmol/L, 1 µmol/L, 0.1 µmol/L, 0.01 µol/L and 0.001 µmol/L) or dimethyl sulfoxide at 37°C for 10 minutes, and then stimulated with LPS or PMA, protein concentrations of p44.42, IKBα, P38 and Jun NH2-terminal kinase were determined by Western blotting. Cyclic adenosine-3',5'-monophosphate (cAMP) of PBMC was measured by enzyme immunoassay kit (Amersham Pharmacia Biotech).

RESULTSY316 blocked TNF production and inhibited the upregulation of TNF mRNA levels in response to LPS, and also prevented the production of IL-1 and IL-6. In contrast, Y316 augmented the production of IL-10 in LPS-stimulated monocytes. Y316 failed to prevent the production of IL-2 and TNF in antigen-stimulated T cells, suggesting that its effects may be cell-type specific. Y316 prevented the phosphorylation and activation of the MAPK, ERK, and therefore appeared to mediate its effects on TNF by acting at an early point in the signaling cascade induced in response to LPS. There was no effect of Y316 on cAMP levels either alone or in the presence of LPS.

CONCLUSIONSY316 appears to be a small molecule inhibiting TNF production, which may act via a novel mechanism. Identification of the target of Y316 may lead to the development of alternative strategies for achieving selective cytokine inhibition.

OBJECTIVETo explore the follow-up visit, outcome and auxiliary diagnosis method on the cases with indeterminate antibody level measured by Western blotting as well as the related biological factors.

METHODSThe cases with indeterminate result were followed up according to the National Guideline for Detection of HIV/AIDS (2009) and samples were collected for HIV antibody detection, p24 antigen and nucleic acid were detected as a supplementary diagnosis at the same time. The samples were also be detected for HBV, HCV, TP, HTLV-I/II, ANA, and AFP, and the results were compared to that of screened positive and confirmed negative cases.

RESULTSA total of 73 were followed up successfully and taken a second HIV test, 25 cases were tested positive and 48 were tested negative for HIV during the follow-up period. For the 25 HIV positive cases, the HIV seroconversion rate was 100.00% at any time point when the interval between the first and returning detection was longer than 1 week. The major Western blotting bands for the cases with indeterminate result were p24 and gp160 and it was different between HIV positive and negative cases in Western blotting band profiles. The consistency and sensitivity of nucleic acid detection were higher than 90.00%, and were higher than that of p24 antigen (69.09% (38/55) and 27.27% (6/22)) (χ(2)(consistency) = 6.875, χ(2)(sensitivity) = 18.893, P < 0.05). The positive rates of ANA and AFP of indeterminate cases excluded from HIV infection were 20.83% (10/28) and 6.25% (3/48) and higher than that of screened positive and confirmed negative cases (0.00%), the difference had statistic significance (χ(2)(ANA) = 19.430, χ(2)(AFP) = 5.520, P < 0.05).

CONCLUSIONIt is critical to get timely diagnosis for the indeterminate cases according to the new national guideline for detection of HIV/AIDS. Nucleic acid detection has higher application value as auxiliary diagnosis for HIV infection than p24 antigen. The increased levels of ANA and AFP may be the factors resulting in the nonspecific indeterminate results.

OBJECTIVETo evaluate the relationship between the incidence of abnormal thyroid function of newborns and maternal hyperthyroidism with antithyroid drug therapy.

METHODThe clinical data of 35 neonates born to mothers with hyperthyroidism from 1983 to 2003 in Peking Union Medical College Hospital were retrospectively analyzed. According to the maternal thyroid function and the antithyroid drugs taken during pregnancy, subjects were divided into different groups.

RESULTSThe proportion of abnormal thyroid function in newborn was 48.6% (17/35). The prevalences of primary hypothyroidism, subclinical hypothyroidism, hypothyroxinemia, and central hypothyroidism were 29.4%, 29.4%, 35.3%, and 5.9%, respectively. The incidence of abnormal thyroid function of neonates whose mothers did not take the antithyroid drugs (ATDs) until the third trimester of pregnancy was significantly higher than those without and with ATDs during the first or second trimester (P < 0.01). The incidence of abnormal thyroid function significantly increased in premature neonates, neonates whose mothers with modest or heavy pregnant hypertension, or neonates whose core serum thyroid-stimulating hormone or serum anti-thyroid peroxidase antibodies levels were abnormal.

CONCLUSIONThe risk of abnormal thyroid function of infants whose hyperthyroid mothers did not take ATDs until the third trimester of pregnancy may be increased. Prompt diagnosis and appropriate treatment of hyperthyroidism in pregnant women are essential for the prevention of neonatal thyroid functional abnormality.
