Objective To evaluate the effects of small dose of antithymocyte globulin(ATG)and zenapax in the induction therapy for kidney transplant recipients.Methods A series of 150 cadaver-donor kidney transplant recipients were randomly divided to 3 groups,ie,small dose of ATG group(total dose,2.1 -3.0 mg/kg;n=72),zenapax group(50mg,on the first and 14th d after operation;n=15)and controls without induction therapy(n=63).Follow-up was 6 months.The rates of acute rejection,delayed graft func- tion(DGF)and pulmonary infection were statistically compared among the 3 groups.Results During a 6-month period,in ATG,zenapax and control groups,acute rejection episodes occurred in 4 cases(5.5%), 1(6.7%)and 10(15.9%),respectively;DGF occurred in 3(4.2%),0 and 8(12.7%),respectively;pul- monary infection occurred in 4(5.1%),1(6.7%)and 3(4.8%),respectively;leucocytopenia occurred in 3(4.2%),1(6.7%)and 5(7.9%),respectively;thrombocytopenia occurred in 2(2.8%),1(6.7%)and 5(7.9%),respectively.Conclusions In the early stage of kidney transplantation,small dose of ATG and zenapax can be the optimal choice for induction therapy.

20% increase in serum creatinine over the last 6 months or progression to the range of 176-308?mol/L.Patients underwent abrupt cessation of cyelosporine and sirolimus maintenance at 1-2 rag/day after administration of 4-6 mg as first loading dose.Concomitant immunosuppression remained unchanged during conversion.Results Targeted sirolimus level was 4-8 ng/mL.Serum creatinine was dropped from pre-conversion level of(242.15?73.04)?mol/L to(188.32?58.96)?mol/L and (173.36?58.08)?mol/L at 3rd and 6th month respectively(P

Dendritic cells (DCs) are uniquely well-equipped antigen (Ag)-presenting cells. This function of DCs, coupled with their remarkable plasticity, renders them attractive therapeutic targets for immune modulation. Recent data have demonstrated a promising role for pharmacologic treatment as a means of generating potent regulatory DCs. Herein, the evidence that the potential of regulatory DC the-rapy is considerable and that there are compelling reasons to evaluate it in the setting of organ transplantation in the near future are discussed in this paper.

OBJECTIVETo observe the effects of bitumen fume on neurotransmitter and ultrastructure of mice brain and to investigate the toxicity of bitumen fume on nerve system of mice brain.
METHODSThe experimental mice were forced to inhale the bitumen fume at different exposure level and in different time periods. The contents of the three transmitters dopamine (DA), norepinephrine (NE), 5-hydroxytryptamine (5-HT) in mice brain were measured by the fluorescence meanwhile ultrastructure of mice brain was observed by electronic microscope. The ultrastructure of mice brain was observed under transmission electron microscopy.
RESULTSThe contents of DA, NE and 5-HT in all groups decreased with the increasing of dose and prolonging of time (after 8 week, with the increasing of exposure lever, the content of DA, NE, 5-HT was respectively 2.194, 2.190, 2.181, 2.178 microg/g and 1.148, 1.138, 1.135 and 1.407, 1.403, 1.395 microg), but the results did not show significant differences. The structure of the mitochondria changes included the swollen mitochondria, chromatin margination, pyknosis and apoptosis in neuro cells and the processes of swollen astrocyte cells.
CONCLUSIONThe bitumen fume could induce changes of the ultrastructure of mice brain and affect the contents of neurotransmitter of mice brain.

RIG-I-like receptors (RLRs) belong to pattern recognition receptors, which perform significant roles in antiviral responses. RLRs can initiate a cascade of signaling transduction that induces the production of type I interferon and activates the interferon signaling pathway, ultimately resulting in antiviral responses. In the course of evolution, viruses have been constantly counteracting host immune systems to facilitate their own survival and replication, and have developed a set of antagonistic strategies. These mainly comprise elusion, disguise and attack strategies to eliminate the activation of RLRs. In virus-infected cells, RLRs recognize viral RNA and then induce antiviral responses. A better understanding of viral antagonistic strategies against RLRs will provide insights into the development of new antiviral medicines. This mini-review concludes that there are three main antagonistic strategies by which RNA viruses can counteract the activation of the RLRs pathway. It aims to provide references and insights for similar studies on viral antagonism in an array of RNA viruses.

Designed the degenerate primers of alcohol dehydeogenase and L-lactate dehydrogenase to aug- ment Ethanoligenens harbinense B49 genomic DNA, and obtained about 780 bp and 610 bp PCR product respectively. Augmented flank sequences of the two PCR fragments with the Cassette PCR method. Similar- ity alignment showed that the products of the cloned DNA were very high similar to those of alcohol dehy- drogenase genes and L-lactate dehydrogenase genes respectively. One of the two sequences was 1902 bp long, and the ORF of adh was 1101 bp long and encoded 366 amino acids. Its putative molecular weight was about 39.71 kD, its calculational isoionic point was pH 5.93. The maximal identity and positive was 51% and 73% with Clostridium thermocellum ATCC 27405 adh. The other one was 2490 bp long, and the ORF of adh was 951 bp long and encoded 316 amino acids. Its putative molecular weight was 34.23 kD, its calcula-tional isoionic point was pH 6.09. The maximal identity and positive was 55% and 74% with Bacillus megaterium L-ldh. Successfully cloning these two genes would not only enrich the gene resources of L-lactate dehydrogenase and alcohol dehydrogenase genes, but also give the scientific warrant for the meta- bolic engineering research and the construction of the gene-engineering bacteria.

Objective To evaluate the effect of operation on aged women with breast cancer. Methods The clinical data of the 166 patients recruited from 1989 to 2004 were retrospectively analyzed. Results One hundred and sixty six patients were all treated by operation. The modified radical mastectomy was performed in 98 cases(59.0%), radical masteetomy in 21 cases(12.7%), mastectomy in 29 cases (17.5%), palliative operation in 18 cases (10.8%). After operation, one hundred and twenty six patients received chemotherapy, twelve radiotherapy and 73 endocrine therapy. The rates of postoperative complications were 10.8%, no patients died during operation. The overall postoperative 3-and 5-year survival rates were 82.2% and 65.2% respectively. Conclusions The effect of surgical treatment and its combination with other adjunct therapies is satisfactory for aged women with breast cancer. Different types of operations should be performed for different patients. Ageing is not a contraindication of the operation. Surgery should be combined with medical therapy to reduce the concomitant diseases and postoperative complications.

Apoptosis of PK-15 cells induced by Foot-and-Mouth Disease Virus (FMDV) in vitro was reported in this paper. Typical cell apoptosis was detected by use of Hoechst 33258 fluorescence probe, agarose gel electrophoresis and in situ end-labeling (TUNEL). After PK-15 cells were infected by titration of 4.8 lg TCID50/mL FMDV for 32 h, apoptosis characteristics of nuclear condensation, fragmentation, accompanied by apoptotic bodies formation (Hoechst 33258 staining), 180-200 integer-fold sized pieces DNA Ladders (agarose gel electrophoresis) and strong green fluorescence dots (TUNEL) were all exhibited, and cell apoptosis was approximately 20%. In addition, the quantitative analysis of apoptosis in PK-15 cells induced by FMDV showed that apoptosis was correlated with infection of virus, and it was also time-dependent. Results indicate that FMDV can induce apoptosis of host cells and apoptosis plays an important role in the cytopathogencity effect of FMDV.
