Objective To investigate the anti-tumor effects of hydroxycamptothecin ( HCPT ) with different lactone ratios on the mice models of H22 hepatoma. Methods Mice models of H22 hepatoma were established. Tumor inhibiting rates of HCPT with different lactone ratios ( 0%, 25%, 50%, 75%, 100%) and the growth status of model mice before and after chemotherapy were observed. Serum biochemical indices were determined to investigate the effects of HCPT with different lactone ratios on hepatic and renal function of the mice. Results Positive control drug and HCPT with different lactone ratios all inhibited the tumor in mice with H22 hepatoma, the inhibition rate was 65. 30%, 12. 57%, 49. 23%, 75. 47%, 90. 06% and 93. 22%, respectively. Compared with the model control group, the living conditions of the mice in HCPT groups were improved. With increasing of lactone ratios, the hepatic injury was alleviated markedly, but the renal injury was aggravated. Conclusion There is a positive correlation between lactone ratios and its anti-tumor effect, and HCPT with 75% lactone can achieve preferable anti-tumor effect with less toxicity as compared with that with 100% lactone ratio.

Obtaining soil bacterial DNA of good quality is a key step in soil bacterial ecology study.A quick, efficient,sensitive and stably method of DNA extraction from soil were established by combining strongpoints of two kits(Soilmaster kit and DNA IQ~(TM)kit).In addition,the 16S rDNA gene and T-RFLP(Terminal restriction fragment length polymorphism)were used in the analysis of soil bacterial community diversity and the result show that T-RFLP is a powerful tool for bacterial community study.

Objective To summarize the experience in application of the bovine jugular vein valved conduct in right ventricular outflow tract (ROVT) reconstruction. Methods Totally 14 patients [6 male, (6.3?5.4) years old] underwent ROVT reconstruction from February 2004 to March 2005 was recorded, and the function of the implanted bovine jugular vein valved conduit was evaluated by Doppler echocardiography one month later after operation. Results There was no perioperative morbidity related to the bovine jugular vein valved conduit. 14 patients were discharged well. One month after operation, echocardiography showed that reconstructed ROVT was patent, and only four implanted conduits had mild regurgition. Conclusion The bovine jugular vein valved conduit provides the favorable hemodynamic performance and thus could be an excellent substitute for the homograft in the reconstruction of ROVT. The mid- and long-term outcomes required further study.

The study reports the detection of neuroprotective effect of 10 kinds of coumarin derivatives and explores their possible mechanism. MTT method was used to screen the neuroprotective effect of 10 coumarin derivatives on neurotoxic agents (Aβ25-35 and rotenone) or OGD (oxygen-glucose deprivation). A compound with better protective effect was obtained. Then the effect of this compound on neurotoxic agents on PC12 was detected by the morphological observation. Furthermore, the effect of compound 3 on microglia with lipopolysaccharide (LPS) induced inflammation was detected. And the inflammatory factor was tested. Finally, direct free radical scavenging ability was detected. Compound 3 was found to be the best compound through three neurons toxic models. Not only compound 3 ameliorated cell viability reduced by three neurons toxic models, but also significantly inhibited the production of inflammatory factor (TNF-α and IL-1β). And its free radical scavenging ability is very good, especially the effect on superoxide anion, which is comparable with vitamin C. The significant scavenging effect of compound 3 on superoxide anion might be the mechanism of the neuroprotection. Compound 3 as a potential neural cell protective agent merits further investigation.

OBJECTIVETo investigate effects of the variation of immune function in high humidity environment in different time, and lay a foundation for further study of the related mechanism.

METHODThirty SD rats were divided into 3 groups (n = 10): 20 day group, 40 day group in 90% relative humidity chamber and control group in normal relative humidity. Peripheral blood and spleens were collected to detect the levels of T lymphocyte subsets by Flow Cytometery.

RESULTSIn peripheral blood of the 20 day group rats, the CD3+ %, CD4+ %, CD8+ % and CD4+/CD8+ were 52.91 +/- 6.27, 37.80 +/- 4.11, 14.85 +/- 3.73 and 2.72 +/- 0.82 separately. Expect CD3+ %, they all had significant differences (P < 0.05). In addition, the data of the 40 day group rats showed no diversity in statistics. In spleen, CD8+ % of the 20 day group rats was 6.23 +/- 2.87 with significant differences (P < 0.05) and IgG, IgA and IgM did not change a lot in blood serum of the high humidity groups except C3 of the 20 days group (P < 0.05).

CONCLUSIONIn high humidity environment, the immune function of the rats increased in the initial stage. As time went on, the immune function gradually went to normal level through the self adjustment.

Objective To investigate the protective effects of Bcl-2 associated with athanogene-1 (BAG-1) gene on human neuroblastoma cells (SH-SY5Y) injury induced by hypoxia/reoxygenation,and its influence on heat shock protein 70 (HSP70) expression.Methods The SH-SYSY cells at logarithmic growth phase were collected.Lenti virus mediated RNA interference (RNAi) technology was used to suppress the BAG-1 expression.The cells screened out can be divided into four groups:the cell control group with no lentivirus infection,lentivirus control group (containing only fluorescein protein lentivirus infection),BAG-1 siRNA group (BAG-1 siRNA silencing group),including BAG-1 siRNA-α group and BAG-1 siRNA-β group with lentivirus containing fluorescein protein (GFP) but at different BAG-1 siRNA target sites of silencing.Western Blot was used to detect the protein expression of BAG-1 and HSP70 in target cells after infectious recombination lentivirus for 72 hours;the Cell Counting Kit-8 (CCK-8) was used to detect the activity of four different group cells after hypoxia;the flow cytometry was used to detect the cell apoptosis;the HSP70 mRNA transcription level were detected by real-time fluorescent quantitative reverse transcription-polymerase chain reaction (RT-qPCR) respectively in each group.Results After lentiviral infection for 72 hours,the Western Blot results showed that in the two BAG-1 siRNA silencing groups,the interference effect of BAG-1 siRNA-β group was superior to that of BAG-1 siRNA-α group.The cell viability of each group showed an increase followed by a decrease with the prolongation of hypoxia time,and reaching the peak at 8 hours.After hypoxia for 8 hours being given,the cell viability in BAG-1 siRNA-β group was significantly lower than that of the cell control group,lentivirus control group and BAG-1 siRNA-α group (A value:0.59 ±0.09 vs.0.94±0.12,0.90± 0.11,0.91± 0.14,P ＜ 0.01);the cell apoptosis rate was obviously higher in BAG-1 siRNA-β than that in the above three groups [(34.63 ± 3.46)％ vs.(14.83 ± 3.75)％,(19.93 ± 6.49)％,(16.40± 1.18)％,all P ＜ 0.01].There were no statistically significant differences in the HSP70 protein level and mRNA transcription level between BAG-1 siRNA-3 grroup,and the cell control group,lentivirus control group and BAG-1 siRNA-α group respectively (all P ＞ 0.05).Conclusion BAG-1 gene can play a role in protection of hypoxia nerve cells,reduce the apoptosis,and its protective effect can be independent of HSP70 gene.
