There are still some flaws in the private non-profit hospital supervision system since those hospitals recently began to grow in China. The paper aims to analyze the access and changing processes from the non-profit to profit hospitals and the non-profit character supervision of the private non-profit hospitals based on the literature and survey data in Hubei, Guangdong and Jiangsu Provinces. It also puts forward some suggestions on the private non-profit hospitals development including how to optimize the access process, increase taxes or liquidation in the chan-ging process, and establish the coordination supervision mechanism for the non-profit Character in China.

im To study the structure-function relationship of hTNFα . Methods We compared the cytotoxicity, receptor binding ability and toxicity in animal body of wild type(wt)hTNFα with its mutants including R2K-, N30S-, R32W-, L157F-hTNFα , and two multi-site mutants(R32W-L157F-hTNFα and R2K-N30S-R32W-L157F-hTNFα ). Results We found that the two multi-site mutants remained similar cytotoxicity to several human tumor cell lines as wild type hTNFα . However, their cytotoxicity to L929 cells were decreased sharply as compared with those of wt hTNFα . The two multi-site hTNFα mutants had lower binding activity with hTR75 than hTR55. We also found that compared with the wild type, the LD50 of the mutant R32W-L157F-hTNFα was decreased about 300 fold and the dose of mutant R2K-N30S-R32W-L157F-hTNFα resulted in 30％ death was 700 folds lower than LD50 of wt hTNFα . To certify the systematic toxicity of the mutant R2K-N30S-R32W-L157F-hTNFα , we assayed its toxicity to monkeys and found that its systematic toxicity was lower than that of wt hTNFα. Conclusion A 4-site mutants(R2k-N30S-R32W-L157F-hTNFα )of hTNFα is obtained, which the mutant may possess potential application value in clinical therapy.

Objective To investigate the influence of β-catenin gene deletion on Stat-5α phosphorylation in bcr-abl induced leukemia cells. Methods The established conditonal hematopoitic β-catenin knockout mice were used to isolate bone marrow cells. Exogenous bcr-abl fusion gene was transduced to these bone marrow cells by retroviral infection with intent to transfom them to leukemia cells.Immunofluorescence was performed to detect the phosphorylation status of Stat-5α in both β-catenin deletion cells and control cells. bcr-abl transcription and protein levels were evaluated with real-time PCR and western blotting. Results Phosphorylation of Stat-5α was reduced significantly in β-catenin deletion leukemia cells on comparison with control cells despite that total Stat-5α protein showed no obvious changes. Total tyrosine phosphorylation and bcr-abl protein expression were reduced in bcr-abl induced β-catenin deletion CML cells,on the contrary, both of the reduction were not seen in bcr-abl induced β-catenin deletion ALL cells.Conclusion Loss of β-catenin inhibits both Stat-5α phosphorylationin and bcr-abl expression in bcr-abl induced leukemia cells.

Purpose　To explore the possibility and the effect of therapeutic bronchial asthma by antisense oligonucleotid.　Methods　Based on the IL-5 cDNA sequence of mouse,a segment of antisense oligonucleotid was designed and synthetized.5′-labeling of antisense oligonucleotid was signed by T4 PNK in order that the efficiency of stearylamine liposome in transfe-ting antisense oligonucleotid can be evaluated. Astham model was duplicated with ovalbumin (OVA) absorbed to aluminum hydroxide. T lymphocytes of mice were separated by nylon fiber method,then T lymphocytes transfected a different content of antisense oligonucleotid with stearylamine phys. positive liposome were cultured respectively in order to observe the effect of antisense oligonucleotid on IL-5 produced by T lymphocytes. IL-5 levels in the supernatants of T lymphocytes culture were determined by ELISA.　Results 　Stearylamine liposome could markedly increase the efficiency of antisense oligonucleotid transfection. The efficiency of antisense oligonucleotid transfection was the best at 1∶15 m/m(antisense oligonucleotid and SA liposome) and it was increased approximately 12 times.In healthy and asthma Balb/c mice, IL-5 was not detected in the supernatants of T lymphocytes culture without challenge with OVA.However,IL-5 was increased markedly in the supernatants of T lymphocytes culture challenged with OVA. After transfecting a different concentration antisense oligonucleotid, IL-5 levels in the supernatants of T lymphocytes culture were significantly lower than those in control cells without antisense oligonucleotid transfection. IL-5 levels decreased from (44.60±6.23) to (30.70±7.362),(17.20±6.181) and(8.16±2.34)pg/ml respectively. And IL-5 synthesis was inhibited by 31.17% , 61.43% and 81.7% respectively. 　Conclutions　IL-5 synthesis could be obviously inhibited by antisense oligonucleotid and showed a markedly relation between quantitative and effect. It is supported that the production of IL-5 be inhibited through preventing the transcription of IL-5 from T lymphocytes. The study provides foundation for antisense gene therapeutic asthma.

To explore a new method for analyzing biological molecules that have already been sequenced, an experimental study on an auditory method was carried out. The auditory method for analyzing biological molecules includes audible representation of sequence data. Audible representation of sequence data was implemented by using a multimedia computer. Each mononucleotide in a DNA sequence was matched with a corresponding sound, i.e., a DNA sequence was "dubbed" in a sound sequence. When the sound sequence is played, a special cadence can be heard. In the audible representation experiment, special cadences of different exons can be clearly heard. The results show that audible representation of DNA sequence data can be implemented by using a multimedia technique. After a 5-time auditory training, subjects both in internal testing and external testing can obtain 93%-100% of judgment accuracy rate for the difference between two sound sequences of two different exons, thus providing an experimental basis for the practicability of this method. Auditory method for analyzing DNA segments might be beneficial for the research in comparative genomics and functional genomics. This new technology must be robust and be carefully evaluated and improved in a high-throughput environment before its implementation in an application setting.
