China Pharmacy 2005;0(14):-
OBJECTIVE:To detect and analyze the drug resistance of the AmpC and the extended-spectrum ?-lactamases(ESBLs)in Escherichia coli(E coli)from urinary infections.METHODS:ESBLs was detected by Phenotypic Confirmatory Test and AmpC was detected by improved three dimensional test.RESULTS:The isolating rates of ESBLs(45 strains),AmpC(8 strains)and AmpC+ESBLs in E.coli(5 strains)were 34.6%,6.2% and 3.8%,respectively.The drug resistance rates of ESBLs and AmpC-producing E.coli was higher than those of the strains without producing ESBLs or AmpC.CONCLUSION:Production of AmpC and ESBLs in ?-lactam antibiotics was the main resistance mechanism against E.coli.Carbopenems should be regarded as the first choice in clinical empirical medication for enzyme-producing strains.

Journal of Practical Radiology 2000;0(12):-
Objective To analyze the CT features of large adrenal adenoma and to compare the pathological features of large adenoma and small adenoma in order to improve the diagnosis of large adenoma.Methods The unenhanced and enhanced CT images of 14 patients with large adrenal adenoma,proven surgically and pathologically and pathological features of small adrenal adenomas in 30 cases were retrospectively reviewed.The pathological features were evaluated in the cell composition,the incidence of cystic degeneration and hemorrhage of large adenoma and small adenoma.Results 14 large adenomas were unilateral and single,3 had distinct margin and 11 had indistinct margin,14 showed regular contour of round or ellipse,the size of tumors were 5 cm?5.5 cm~18 cm?20 cm.14 large adenomas presened heterogenous density in unenhanced CT study with CT value of-36~51 HU,and 3 showed calcification and 6 showed cystic degeneration.Most of the 14 adenomas presented heterogenenous enhancement after contrast administration.Pathologic examination indicated that the clear cells were predominant in the cell composition of small adenoma,while in the case of large adenoma,the proportion of compact cell predominance was equivalent to that of the clear cell and compact cell concomitance.3 small adenomas and 6 large adenomas had cystic degeneration,5 small adenomas and 4 large adenomas had hemorrhage respectively.Statistical analysis suggested that large adenoma had higher incidence of degeneration than that in small adenoma,while no difference was found in the cell composition and incidence of hemorrhage between large adenoma and small adenoma.Conclusion The large adrenal adenomas have higher incidence of degeneration than that in small adenoma,while no difference is found in cell composition and incidence of hemorrhage between large adenoma and small adenoma.
4.Neuroimaging and treatment evaluation of amblyopia by function-MRI
International Eye Science 2015;(4):636-638
In the past, the ways to amblyopia neural mechanism research are given priority to visual electrophysiology and so on, which express the result use two -dimensional form, these ways mainly research the functions of the state before the lateral geniculate body. For the study of optic center, animal models are used to research it. But these kinds of methods are unable to accurately detect amblyopia neural mechanisms of human beings. Vulnerable to a variety of factors, it is difficult to finish the amblyopia treatment effect evaluation. Functional magnetic resonance imaging ( fMRI ) can reflect the three-dimensional visual cortex neuron activity noninvasively and accurately, and give rise to amblyopia neural mechanism and therapeutic effect evaluation. Therefore, in this paper, the amblyopia neural mechanisms and visual center after treatment effect evaluation of fMRI research progress are summarized.
5.The effect of acupunctural and moxibustional therapy on the apoptosis of breast cell MCF-7

Objective:To observe the effect on the apoptosis of breast cancer cell MCF-7 with acupunctural and moxibustional therapy.Methods:Zusanli and Sanyinjiao neiguan in both sides of female Wistar mice were acupunctured and moxibusted.MCF-7 cell was cultirated with the serum.To detecte the cytoxicity with MTT,and detecte the apoptosic rate and Fas expression rate with flow cytometry after 72 hours.Results:The Fas expression was obviously increased upto 57.70% after 72h.The proliferation of MCF-7 was inhibited remarkably.The inhibition rate were 17.55%,24.71% and 31.85% after 12h,24h and 72h.The apoptosic rate were 8.72% and 10.18% after 72h,remarkably higher than the control group(P

The paper first analyzes the current status of and existing problems with the management personnel in domestic third-tier hospitals and expounds from such angles as work motives, knowledge structure and personality the necessary qualities that hospital management personnel should possess. Then it argues on the basis of analyses from such perspectives as methodology, disciplinary system development and macro policy environment that only through appropriate training in hospital management can the current status of the management personnel in domestic hospitals be changed, the professional advancement of the management personnel in the third-tier hospitals be genuinely realized, and the support and impetus for maintaining the competitiveness of domestic third-tier hospitals in the medical market be provided.

Objective To observe the effect of Pingchuanlingchongji (PCL) on the auricular microcirculation of mice and to investigate the effect mechanism of the treatment for asthma. Methods 50 mice were randomly divided into five groups, group 1 and group 2 were given 0.9% NS (25 mL/kg) as control group; group 3 was given aspirin (0.25 g/kg), 4 group was given low-dose (1.1 g/kg) PCL, group 5 was given high-dose (2.2 g/kg) PCL. Last for seven days. We injected Posterior Pituitary Injection (0.5 U/mL) on the rear vein of 2-5 group mices after the last time of given druy. The diameter of micro-artery in mice auricular, the diameter of micro-vein and blood flow speed were observed. Results As compared with contral group, PCL could expand significantly the diameter of micro-artery and the diameter of micro-vein in mice auricular (P

Objective To examine the heating capability of thermoseeds in isolated hepatic tissues.Methods Isolated hepatic tissues were heated uniformly to 37 ℃,meanwhile the thermoseeds and thermocouples were planted using a template paralleling with the magnetic line.Afterwards,the tissues were treated in an extracorporeal magnetic field of 120-123 gauss at a frequency of 113-116 kHz for 30 minutes.At the meantime,the temperature was recorded by a computer through thermocouples. Results The temperature of the tissues raised markedly with a largest change of 14 ℃.The heating area became hard and showed a gradual change of color(white-yellow-brown).The final temperature was negatively correlated with distance when using same number of the thermoseeds(r=-0.96017 to-0.99767,P=0.0023 to 0.0398),and positively correlated with the number of thermoseeds when measuring at a same point(r=0.93775 to 0.99270,P=0.0007 to 0.0185)except for the center group(r=0.93936,P=0.0606).Conclusions Thermoseeds inductive heating technology can achieve an appropriate temperature in isolated hepatic tissues.In certain extent,the temperature increase the number of thermoseeds and heating distance.
