Objective To investigate the incidence and influencing factors of aldosterone escape in patients with non-diabetic nephropathy by RASI-therapy. Methods A total of 104 patients with non-diabetic nephropathy were treated with ARB or combination therapy of ACEI and ARB in a mean follow-up period of 12 months. Aldosterone escape was determined according to the change of plasma aldosterone concentration before and after treatment during 6-month and 12-month ACEI/ARB treatment, while the influencing factors of aldosterone escape in patients with non-diabetic nephropathy was also analyzed after therapy with RASI . Results In 12 months, the incidence of aldosterone escape was significantly higher than that in 6 months (26.92% vs. 14.42%, P = 0.007). After 12-month treatment, the difference was statistically significant in incidence of aldosterone escape among different stages of CKD (P = 0.027). Compared with 6-month incidence of aldosterone escape in the losartan group, 12-month incidence increased evidently (P = 0.020). The Ald level was positively correlated with urinary protein excretion and the Scr level (r = 0.431, P = 0.003 and r = 0.336, P = 0.009, respectively), and negetively correlated with levels of the eGFR (r = -0.275, P = 0.006). Univariate Logistic regression demonstrated that risk factors of aldosterone escape included pre-treatment values of the urinary protein excretion (OR = 3.671, P = 0.028) and the eGFR (OR = 0.972, P = 0.019). Multivariate Logistic model revealed pre-treatment values of the eGFR was positively associated with aldosterone escape (OR = 0.970, P = 0.012). Conclusion The incidence of the aldosterone escape increases along with the time of treatment. Renal function has correlated with aldosterone escape and pre-treatment value of the eGFR is an independent risk factor of aldosterone escape.

Objective To construct the eukaryotic expression vector of pprI gene from Deinococcus radiodurans R1 and investigate its radioresistant effects in eukaryotic cells.Methods A recombinant vector pEGFP-c1-pprI was constructed by DNA recombinant technique.The empty vector pEGFP-c1 and the pEGFP-c1-pprI were transferred into human lung epithelial cells Beas-2B by LipofectamineTM 2000,respectively.Then the infected cells were screened in order to develop a cell line with stable expression of pprI gene.Cell survival rate was tested by clone-forming assay.Cell cycle distribution and apoptosis were detected by a flow cytometry.The fluorescence intensity of reactive oxygen species (ROS) was observed by a fluorescent microscope.γ-H2AX foci in the irradiated cell was detected by immunofluorescence.Results The eukaryotic expression plasmid of pprI prokaryotic gene was constructed and PprI fusion protein was expressed in human lung epithelial cells successfully,and the cell line (2BG) with a stable pprI gene expression was established.After irradiation,the cell survival fraction of 2BG cells was significantly higher than Beas-2B cells so that the value of D0 、Dq and N of the survival curve were increased.Moreover,the fluorescence intensity of ROS and the number of γ-H2AX foci in 2BG cells were also lower than those of B eas-2B cells(F =16.73,19.47,6.94,P ＜ 0.05).Between these two cell lines,the apoptosis rate and cell cycle G2 arrest also had significant difference (F =139.73,237.92,P ＜ 0.05).Conclusions The pprI gene from Deinococcus radiodurans RI can be stably expressed in the eukaryotic cells and it allows the transferred cells to have a radioresistant function.

Objective To investigate the relationship between eosinophil and in-stent restenosis in acute coronary syndrome patients. Methods One hundred and fifity-one ACS cases werenenrolled in this study. According to the results of coronary angiography (the stented segment lumen loss over 50% was judged to be ISR), patients were divided into the restenosis group and the non-restenosis group. Results Based on the logistic analysis, no significant association was found between eosinophil and ISR, and even after adjustment of related risk factors (P > 0.05). The stratification analysis showed that the high level of eosinophil might increase the risk of ISR in ACS patients with history of hypertension (P = 0.038) and myocardial infarction (P = 0.032). Conclusion Eosinophil may be associated with the risk of ISR in ACS patients with history of hypertension and myocardial infarction. The underlying mechanisms need to be elucidated in further study.

Objective To establish a technical route for the efficient expression and purification of PprI protein from Deinococcus radiodurans R1 by using eukaryotic Pichia pastoris.Methods The encoding sequence of the Deinococcus radiodurans pprI gene was modified according to the preference of Pichia pastoris' codon.Modified pprI gene was fully synthesized with PCR and a 6 × His tag was added at its Nterminal.The PCR products were purified and then cloned into Pichia pastoris expression vector pHBM-905A.After utilizing Cop I and Not I double enzyme digestion and retrievering linear objective fragment,new pprI gene was transformed to the GS115 strain of Pichia pastoris.The obtained Pichia pastoris transformants were induced to express.Culture supernatants were detected by SDS-PAGE,Western blot,and mass spectrometry.A Ni-NTA column was uesd to purify the target protein and the BCA method was used to determine protein concentration.Results The coding sequence of new synthetic Deinococcus radiodurans pprI gene was correct.The purpose protein band of a molecular weight of 43 000 was detected in the culture supernatant of transformed Pichia pastoris strains by SDS-PAGE and Western blot.The mass spectrometry confirmed that it was the Deinococcus radiodurans PprI protein.When the concentration of imidazole was 250 mmol/L,the elution rate of PprI protein was the highest.The purified protein concentration was 0.35 mg/ml measured by BCA method.Conclusions This study has successfully constructed a new pprI gene and the recombinant strain of Pichia pastoris secreting PprI protein,and established a technical route for the efficient expression and purification of PprI protein.

AIM: To investigate the effects of ?-elemene,extracted from curcuma wenyujin,on proliferation, cell cycle and apoptosis of human multiple myeloma RPMI-8226 cells. METHODS: The effect of ?-elemene on the growth of human multiple myeloma RPMI-8226 cells was studied through MTT assay,cell cycle and apoptosis was studied by combined Annexin-V protein iodide staining,The morphological changes was studied by combining Hoechst33342-PI staining. RESULTS: ?-elemene inhibited the proliferation of RPMI-8226 cells in a time-and dose- dependent manner. Compared with the control cells,the proportions of the RPMI-8226 cells in the G0 /G1 phase rose,and the proportions of the RPMI-8226 cells in the S and G2 /M phases fell decreased. RPMI-8226 cells treated with ?-elemene for 48 h induced apoptosis in a dose-dependent manner. CONCLUSION: ?-elemene is able to inhibit the proliferation of RPMI-8226 cells by arresting the cell cycle and inducing the cell apoptosis.

Objective To investigate the imaging and biodistribution of 99Tcm labeled peptide ( phage-SHSWHWLPNLRHYAS) high-binding VEGF receptor 3 in nude mice with ovarian cancer. Methods We used NHS-MAG3 as the bifunctional chelating agent and synthesized the peptide above. It was completed with pre-stannous direct labeling by 99Tcm and then the labeling efficiency was determined by paper chromatography. The tumor bearing mice were injected via tail veins with radiolabeled peptide. The tumors were imaged with single photon emission computed tomography ( SPECT) . We measured and calculated the biodistribution of the radiolabeled peptide. Results The labeled rate was 95. 27% and the radiochemical purity was 96% . Under a SPECT apparatus,we observed tumor location image at 1 h post injection and the tumor images was the clearest at 3 h post injection,with the injected dose per gram of tissue ( % ID/g) of ( 30. 20 ? 6. 89) at the tumor sites. The tumor/muscle ratio was 13. 13. Conclusion Our peptide can accumulate in the tumor masses. It is hopeful to be used as an ovarian cancer targeting vector for diagnosis and therapy of the cancer.
