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.

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.

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.

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

Objective To observe the clinical features of pulmonary infections secondary to lung tuberculosis and explore the nursing care strategy in this condition.Methods Retrospective analysis on in patients of lung tuberculosis with secondary pulmonary infections from Sep 2000 to Aug 2002.Results Of 53 tuberculostic patients who were suffered from lung infection after hospitalization,majority were secondary tuberculosis including chronic fibrosis with cavity information in 21 cases and exudative in 17 cases while other typies like miliaris disseminata in 14 cases.Total mortality was 11.3%.Conclusion Intensive and specific nursing care could reduce the prevalence of nonsocasimal infection in tuberculostic in-patients and improve the outcome.

To summarize the etiological factor and to assess the therapeutic effect for neovascular glaucoma(NVG).Methods A retrospective study of 28 cases (29 eyes) with NVG was performed. The mean age, proportion of sex and primary ocular disease, incidence of symptom, sign and postoperative complication were analyzed. Results 78 6% of the patients were over 40 years old. 62% of the patients were secondary to the ocular ischemic disease such as central retina vein occlusion and proliferative diabetic retinopathy. The clinical characters included intraocular pressure (IOP) increasing, pain, mixed conjunctival congestion and rubeosis iridis. The mean IOP reduction was 19.5 mmHg in 29 eyes after antiglaucomatous drags treatment and 19.13mmHg in 23 eyes after Hunan aqueous humor drainage (HAD) implantation. The common postoperative complications were flat anterior chamber and choroidal detachment. The success rate of HAD implantation was 87%.Conclusions NVG was commonly secondary to ocular ischemic disease. Although prevention was the principal, reducing IOP and ameliorating ischemic situation were as the same important.

Objective To systematically evaluate the effects of compression stockings for preventing post-thrombotic syndrome after giant surgery in department of orthopaedics.Methods Randomized controlled trials about compression stockings were searched and analyzed no matter written in Chinese or English.The effects of compression stockings is determined by Meta-analysis with Review Manager 5.0.Results 4 papers were included in this research,among which,one was domestic,and another three were abroad.Heterogeneity was small when the data was merged,which suggested that compression stocking for preventing post-thrombotic syndrome was effective.Conclusions Compression stockings can be safely used to prevent post-thrombotic syndrome after giant surgery in department of orthopaedics.

Purpose：To study the incidence of pneumonia, pathogenic bacteria and prognosis in patients with neoplasm after chemotherapy.Methods：Sputum culture was made by routine method. Then,to determine the kinds of bacteria bioMrieux ATB expression was used, and general drug-sensitivity test was done by Kirby-Bautr method.Results：Fever occured in 27.3% patients after chemotherapy, while pneumonia in 11.3% patients. 13 kinds of bacteria, 72 strains of bacteria and 2 kinds of fungi were found in 68 positive culture samples. The infection rates were 76.5% in infection of single bacteoia，23.5% in infection of two kinds of bacteria and 22.1% in bacteria with fungi. The infection rate of gram-negative bacteria is much higher than that of gram-positive ones (P＜0.01).Conclusions：The incidence of pneumonia in the hospital is higher in patients with neoplasm after chemotherapy. Most pathogenic bacteria are gram-negative and sensitive to aminoglycosides, piperacillin and norfloxacin.
