Objective To analyze the drug therapeutic regimen and duration of the chemotherapy in the spinal tuberculosis in order to determine the best therapeutic regimen and duration of the spinal anti-tuberculo-sis. Methods The medication plan and duration of 890 hospitalized patients with spinal tuberculosis in our hospital from January 2001 to December 2008 were retrospectively investigated. We collected the plan of the initial treatment,retreatment,recrudescence and drug resistance. We also studied the individuation therapeutic regimen of the patients with tuberculosis at other parts or complications. On the basis of these data,we analyzed the interferential appearance that the antituberculosis drug acted on different onsets,manifestations and operations. Results In 890 patients of spinal tuberculosis,596 cases ( 67% ) were initial treatment,294 ( 33% ) were retreatment,recur cases were 110 ( 12. 3% ) ,drug resistance cases were 74( 8. 3% ) ,and those compli-cated with tuberculosis in other parts were 273 ( 30. 7% ) . The main chemotherapeutic regimen was the usual tetragenous protocol ( H12 /R12 /E9 /Z5 /S3) . The retreatment cases were given second-line drugs such as levo-floxacin. The drug resistance cases were also given second-line drugs and intravenous infusion. According to the anti-tubercle bacillus spectrum,individuation treatments were adopted,and the plan was changed in time. The medication duration continued for 9-36 months. All the 890 patients were cured. Conclusion For the treatment of spinal tuberculosis,it is significance to make a efficient and standardized anti-tuberculosis chemotherapy.

Equipping tumor-targeting carrier with cell-penetrating peptide with high transduction efficacy has become a trend. According to the fusion modes and tumor-targeting mechanisms, cell-penetrating peptides can be divided into five categories: first, self-targeting cell-penetrating peptides; second, fusion carriers made of targeting ligands and cell-penetrating peptides; third, cell-penetrating peptide-modified nano-carrier; fourth, tumor-microenvironment-targeting cell-penetrating peptides; fifth, other special cell-penetrating peptides. Fusion carriers, which can not be effectively released into the cytoplasm after transducted into target cells, can be further modified to increase their efficacy. In all, cell-penetrating peptide introduced into tumor-targeting carrier should provide a new era for anti-tumor pharmacy research and cancer therapy.

Objective To explore the content of peripheral blood T lymphocyte subsets and natural killer (NK) cells in diffuse large B-cell lymphoma (DLBCL) in different clinical stages and analyze their clinical significance.Methods Sixty-two DLBCL patients were divided into 3 groups according to clinical stages:stage Ⅱ group (21 cases),stage Ⅲ group (21 cases ),stage Ⅳ group (20 cases).Thirty healthy examiners were selected as control group.Two ml peripheral blood was taken from every person.Peripheral blood T lymphocyte subsets(CD3+,CD4+,CD8+) and NK cell count were detected by flow cytometry(FCM) and CD4+/CD8+ was calculated.Results CD3+ in stage Ⅱ and Ⅲ groups[(854.6 ± 276.9 ) × 106/L,(823.3 ± 211.5)× 106/L] were lower than those in control group[(1268.8 ±684.0) × 106/L] and stage Ⅳ group [(1332.7 ±571.2) × 106/L](P ＜ 0.05).CD4+ in stage Ⅱ,Ⅲ,Ⅳ groups [(433.5 ± 240.7) × 106/L,(423.8 ± 234.8) ×106/L,(423.0 ± 143.8 ) × 106/L] were lower than those in control group [(751.3 ± 367.4) × 106/L] (P ＜0.05).CD8+ and CD4+/CD8+ in stageⅣ group [(861.2 ±634.1) × 106/L,0.5 ±0.3] were significantly higher than those in control group [(455.9 ± 334.6) × 106/L,2.1 ± 1.3],stage Ⅱ group [(390.6 ± 54.1 ) × 106/L,1.0 ±0.8] and stageⅢ group [(377.4 ±493) × 106/L,0.9 + 0.6](P＜0.05).NK cell in stage Ⅳgroup was obviously lower than that in control group[(210.3 ± 122.0) × 106/L vs.(353.3 ± 284.7) × 106/L,P＜ 0.05].And the higher clinical stage was,the lower NK cell was.Conclusions With the clinical stage increasing,the immunity depression and disorder of DLBCL patients become more and more serious,the more tumor burden is,the worse NK cell activity is.

ObjectiveTo explore the relationship between the international prognosis indexes(IPT) and the cell-mediated immunity condition in DLBCL patients. Methods52 DLBCL patients were divided into 4 groups and the FCM was used to examine the T lymphocyte subsets,including CD3+、CD4+、CD8+、NK cells.T lymphocyte subsets absolute value and CD4+/CD8+ ratio were examined. Correlation with IPI were compared among groups.ResultsCD3+ cells in high risk group [(1570.9±370.5)/μl]were higher than other IPI groups;CD4+ cells in DLBCL groups were all lower than normal group(751.3±367.4)/μl]; CD8+ cells in high risk group [(1055.9±523.8)/μl] were higher than other groups; CD4+/CD8+ ratio in middle-high risk group and high risk group (1.0±0.2、0.7±1.0)were lower than other IPI groups and normal group;NK cells in middle-high risk group and high risk group were lower than the normal group[(199.5±68.4)/μl、(171.9±126.9)/μl];Age,clinical stage,body state had correlated with the CD3+ 、CD8+ cells and CD4+/CD8+ ratio of the DLBCL patients' peripheralblood T lymphosyte subsets. ConclusionsThe immunity condition in DLBCL patients has correlated with IPI; With increasing IPI value,the immunity depression and disorder become more serious,NK cells function become worse,and the prognosis is bad too.

Objective To investigate the influence of epigallocatechin gallate ( EGCG)on reactive oxygen species (ROS) in mouse podocytes exposed to high glucose. Methods Mouse podocytes cultured in high glucose were exposed to different concentrations of EGCG (0.2, 10, 100 μmol/L) or α-tocopherol (0.2 μmol/L) for 6, 12, 24 hours. The viability of podocytes was detected by MTT. The intracellular formation of ROS was detected by confocal microscopy with fluorescent probe CM-H2DCFDA and was measured by fluorescence microscopy. RT-PCR was used to examine the expression of p22phox, p47phox and p67phox mRNA in cultured podocytes exposed to different concentrations of EGCG. Results Intracellular ROS generation was significantly higher in high glucose than that in control conditions (P<0.01). EGCG could significantly inhibit ROS induced by high glucose significantly (P<0.01). EGCG (100 μmol/L) led to an inhibition of the increased production of NADPH oxidase components of p22phox and p67phox mRNA in high glucose (P<0.05). The expression of p47phox mRNA in high glucose was inhibited by EGCG(0.2 μmol/L) and ot-tocopherol(0.2 μmol/L) (P<0.05). Conclusion EGCG can protect cultured mouse podocytes from injury of high glucose by inhibiting ROS formation.

he aim of this study was to obtain a cell-penetrating cytoglobin (Cygb), which combines the transmembrane function of cell-penetrating peptides TAT with the anti-aging and anti-fibrotic role of cytoglobin. The Cygb gene was complexed with TAT gene by overlapping PCR, inserted into the vector pET22b to construct the recombinant expression plasmid (pET22b-TAT-Cygb) and then transformed into Escherichia coli BL21 (DE3). The fusion protein TAT-Cygb, whose expression was induced by lactose, was purified by CM Sepharose Fast Flow Protocol and verified by Western blotting. The final TAT-Cygb had a molecular weight of 23 kDa with 95% purity, as shown by SDS-PAGE. As demonstrated by bioactivity experiments, TAT-Cygb exhibited a high specific peroxidase activity up to (422.30 ± 0.36) U/mg. Both TAT-Cygb and Cygb pretreatment group could protect Hacat cells against oxidation of H2O2, but only TAT-Cygb treatment group could remedy cells injuried by H2O2 (RGR = 98%), which was significantly different from Cygb treatment group (RGR = 79%). We successfully obtained the bioactive and cell-penetrating fusion protein TAT-Cygb that has the potential application in anti-aging, anti-fibrotic and anti-cancer.
