Objective To provide the hardware system of EIT with an excellent direct current(DC) power source. Methods The spectrums of the outputs of DC power source and the driving source were analyzed by means of Spectrum Analyzer- E4408B when EIT system was respectively powered by battery, linear power source and switching power source. Based on the numbers and power levels of the spurs of the three power sources and the numbers and power levels of the interferences within the driving source, the influence of the three power sources on the error of measuring was estimated. Meanwhile the EIT system did data acquisition, the overall signal-to-noise-ratio(SNR) of the three power sources at the 18 frequencies were calculated and the influence of the three power sources on the error of measuring was judged. Results With respect to the numbers and power levels of the interferences within the driving source when EIT was powered respectively by the three power sources, the battery output 6 interferences, the highest power of which achieved -78.25 dBm; the linear power source output 6 interferences, the highest power of which achieved -67.11 dBm; the switching power source output 15 interferences, the highest power of which achieved -35.83 dBm. The overall SNRs of the battery at the 18 driving frequencies were higher than that of the linear power source, and the overall SNRs of the linear power source were higher than that of the switching power source. Conclusion The power mode of battery is the best for the hardware of EIT among the three power sources.

Objective To explore the advantages of Argus method by comparing the accuracy and timeliness of Argus and artificial methods for measuring femoral head necrosis area in MRI scanning.Methods Totally 17 patients (31 hips) were measured with Argus and artificial methods respectively for the necrosis area, and then the measuring results and time were compared, and the correlation was investigated between the results and the patients' pain degree, along with that between the results and the extent of femoral head collapse.Results The necrosis area ratios determined by Argus and artificial methods were (33.5±4.08)%and (34.6±4.06)%respectively, with no statistical difference between the ratios (P>0.05). The time consumed by artificial method was (21.3 ±3.62)min, significantly longer than (7.89 ±1.03)min by Argus method, with P<0.001. Regression analysis proved that the necrosis areas were positively correlated with the patients' pain degree, and the correlation coefficient by Argus method was 0.807 8, more than 0.740 9 by artificial method. The femoral heads of 11 cases(16 hips) collapsed in the follow-up period, the necrosis areas were positively correlated with the patients collapse level, but the correlation coefficient by Argus method was 0.783 8, more than 0.726 7 by artificial method.Conclusion Argus method gains high accuracy and timeliness when used in MRI scanning of femoral head necrosis area, and thus is worth popularizing clinically.

The hG -CSF cDNA was cloned by RT-PCR and confirmed by sequencing, which contains the full length of hG-CSF encoding region and parts of 5 '、3' non - coding region. Then the hG - CSF retroviral vector pLGSN was constructed by orientationally inserting the hG-CSF cDNA into the EcoRI/XhoI cloning sites of pLXSN vector. Packaged with CRE and CRIP packaging cell lines which are considered to be unlikely to produce helper viruses, the final pLGSN retrovirion titer reached 1. 1 ?106 CFU/ml. During constitutive passaging, the CRIP - LGSN cell clone produced relatively stable tilers of pLGSN retrovirion, ranging from 6. 8?105CFU/ml to 1. 1?106CFU/ml. By infecting the murine fibroblast cell line NIH3T3 with pLGSN retrovirion, a cell clone designated as NIH3T3 -G -CSF was obstained, secreting 168U/ml G-CSF . The integration and expression of hG-CSF gene in this cell clone were confirmed by Southern and Northern blotting analyses. Western blotting has also detected specifically the hG-CSF protein in the condensed supernalants from NIH3T3-G-CSF cells . After packaging the hG-CSF-secreting fibroblasts with collagen and implanting them into synergenic mice peritoneally , we detected a certain levels of G-CSF in the sera of mice, which suggested the implanted NIH3T3-G-CSF fibroblast cells could constitutively express and release hG-CSF in vivo. Our data showed the constructed hG-CSF retroviral vector could be used to further investigate the fibroblasl-mediated hG-CSF gene therapy .

AIM:To investigate the role of minocycline on glutamate uptake in the periventricular zone and its putative mechanism after hypoxic exposure in neonatal rats.METHODS: A model of hypoxic-ischemic brain damage (HIBD) was developed by putting postnatal 1 d rat pups in 5%O2 for 3.5 h.The glutamate level in periventricular zone was measured by liquid chromatography coupled with tandem mass spectrometry assay ( LC-MS/MS) after hypoxic exposure for 4 h and 1 d.The dynamic changes of glutamate transporters EAAT1, and EAAT2 during developmental period in periventricular zone were determined by Western blot.Moreover, the expression of EAAT1, EAAT2, Iba-1, IL-1β, TNF-αand TGF-β1 was also detected by Western blot after hypoxic exposure for 4 h and 1 d in that region.The effects of mino-cycline on all parameters mentioned above were tested after minocycline treatment at the same time points and in the same region.RESULTS:After hypoxic exposure, glutamate level was increased, but it was decreased after minocycline treat-ment.EAAT1 and EAAT2 kept a low expression level at the first postnatal week, but a predominant elevation was found at the end of the second postnatal week.The expression of EAAT1, EAAT2, Iba-1, IL-1βand TGF-β1 was increased at 1 d after hypoxic exposure.EAAT1 and TNF-αexpression was significantly up-regulated, while EAAT2 was down-regulated af-ter minocycline treatment.CONCLUSION: Minocycline inhibits the increase in the glutamate level after hypoxia in periventricular region of the neonatal rats.The mechanism may relate to the selective regulation of glutamate transporters, rather than the inhibition of neuroinflammation in periventricular zone.
