ABSTRACT
<p><b>BACKGROUND</b>Steady-state bone marrow (SS-BM) and granulocyte colony-stimulating growth factor-primed BM/peripheral blood stem-cell (G-BM/G-PBSC) are the main stem-cell sources used in allogeneic hematopoietic stem-cell transplantation. Here, we evaluated the treatment effects of SS-BM and G-BM/G-PBSC in human leucocyte antigen (HLA)-identical sibling transplantation.</p><p><b>METHODS</b>A total of 226 patients (acute myelogenous leukemia-complete remission 1, chronic myelogenous leukemia-chronic phase 1) received SS-BM, G-BM, or G-PBSC from an HLA-identical sibling. Clinical outcomes (graft-versus-host disease [GVHD], overall survival, transplant-related mortality [TRM], and leukemia-free survival [LFS]) were analyzed.</p><p><b>RESULTS</b>When compared to SS-BM, G-BM gave faster recovery time to neutrophil or platelet (P < 0.05). Incidence of grade III-IV acute GVHD and extensive chronic GVHD (cGVHD) was lower than seen with SS-BM (P < 0.05) and similar to G-PBSC. Although the incidence of cGVHD in the G-BM group was similar to SS-BM, both were lower than G-PBSC (P < 0.05). G-BM and G-PBSC exhibited similar survival, LFS, and TRM, but were significantly different from SS-BM (P < 0.05). There were no significant differences in leukemia relapse rates among the groups (P > 0.05).</p><p><b>CONCLUSIONS</b>G-CSF-primed bone marrow shared the advantages of G-PBSC and SS-BM. We conclude that G-BM is an excellent stem-cell source that may be preferable to G-PBSC or SS-BM in patients receiving HLA-identical sibling hematopoietic stem-cell transplantation.</p>

Objective To investigate the flora distribution and drug resistance status in the Affiliated Hospital of Academy of Military Medical Sciences so as to provide experimental data for clinical doctors to use antibiotics more efficiently.Methods The clinical data of pathogenic bacterial infections over nearly one year in our hospital were retro -spectively analyzed .Results There were 3815 strains of pathogenic bacteria isolated from the sample .The percentage of Gram-positive strains was 36.4%while that of Gram-negative bacteria was 63.6%.The most common bacteria were Esche-richia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Staphylococcus epidermidis.In terms of drug tolerance , Enterobacteriaceae remained highily sensitive to carbapenems .The total resistance rate was 2%-5%.The resistance rate of A.baumannii to meropenem and imipenem was 60%.There were still a few pan-drug resistant strains among K.pneumoniae,A.baumannii and P.aeruginosa,but there were no drug resistant strains to vancomycin , tige-cycline and linezolid in Staphylococcus.The resistance rate of Enterococcus faecium to vancomycin was 9%.The bacteria were distributed predominantly in ICU ,Department of Hematology and Department of Oncology .The samples were mainly composed of phlegm specimens .Conclusion The high distribution in the three departments mentioned above is largely re-lated to the diseases being treated .The specimens from the lower respiratory tract show more types of bacteria that are mostly drug-resistant, and the isolating rate of vancomycin resistant Enterococcus and carbapenems resistant K.pneumoniat is com-paratively high .
ABSTRACT
Objective To detect the expression of KiSS-1, KiSS-1R and MMP-9 in hepatocellular carcinoma (HCC). To study the correlation of KiSS-1, KiSS-1R and MMP-9 expression with invasion and metastasis of HCC, and to explore the underlying mechanisms. Methods The expression of KiSS-1 , KiSS-1R mRNA in 33 HCC samples, 26 non-neoplastic adjacent liver tissue samples and 13 non-neoplastic distant liver tissue samples were detected by RT-PCR. Tissue chips were constructed by modified manual tools, which contained HCC, non-neoplastic adjacent liver tissues, non-neoplastic distant liver tissues, normal liver tissues and intrahepatic metastasis lesions. The expression of KiSS-1 and MMP-9 protein was determined by tissue chips, immunohistochemistry and semi-quantitative image analysis in 150 HCC, 137 non-neoplastic adjacent liver tissue, 98 non-neoplastic distant liver tissues, 16 normal liver tissues and 37 intrahepatic metastasis lesion samples. Results The results of RT-PCR showed that compared with the non-neoplastic adjacent liver tissues and the non-neoplastic distant liver tissues, the expression of KiSS-1 mRNA in HCC was significantly lower (P＜0.01). The expression of KiSS-1R mRNA did not changed in HCC and non-neoplastic liver tissues (P＞0.05). The expression of KiSS-1 protein was lower in HCC with metastasis and in clinical stage Ⅲ than that in those with non-metastasis, and in clinical stages Ⅰ and Ⅱ . It was also higher in the primary than in the metastasis lesions (P＜0.01, respectively). The expression of MMP-9 was higher in tumors having peplos invasion and metastasis than in those with negative peplos invasion and non-metastasis. It was lower in the primary than the metastasis lesions (P＜0. 01, respectively).Negative correlation between KiSS-1 and MMP-9 expression was found in HCC(r=- 0.340,P＜0.01). Conclusions The imbalance between KiSS-1 and MMP-9 expression might play an important role in enhancing the invasive and metastatic capacity of HCC. Loss of KiSS-1 expression might predict an aggressive clinical behavior and was associated with metastatic potential in HCC.

ABSTRACT
Ampicillin sodium was embeded in ethylcellulose (EC) nanospheres made of low-molecular-weight EC. Low-molecular-weight EC was attained with ethylcellulose being degraded by 34% (w/w) nitric acid; Fourier transform infrared (FTIR) spectroscopy, 13C-NMR, element analysis confirmed that the basic structure and major properties of low-molecular-weight EC maintained agreement with those of undegraded EC except that the polymerization degree of EC decreased. Wide-angle X-ray diffraction demonstrated that the crystallinity of degraded EC decreased. Ampicillin sodium loaded EC nanospheres were characterized by transmission electron microscopy, FTIR and in vitro drug release. Molecular weight of EC would affect the size of nanospheres, distribution and drug encapsulation efficiency. Drug loaded nanospheres resulted in the drug control release in 3-10 hours.
