RESUMO
Objective To establish a preprocedure nomogram for predicting contrast-induced acute kidney injury (CI-AKI) after coronary angiography (CAG) or percutaneous coronary intervention (PCI).Methods Clinical data of 245 patients underwent CAG or PCI were collected.CI-AKI prediction nomogram integrated preprocedural predictors was established with clinical characteristics associated with CI-AKI which were selected with the LASSO regression model,and CI-AKI risk scores were calculated.The ROC curve was constructed to calculate the risk score cutoff.Results The occurrency of CI-AKI was 13.88％ (34/245).Sex,diabetes mellitus,lactate dehydrogenase level,high-sensitivity C-reactive protein,drinking years,chronic kidney disease (CKD),stage of CKD,stroke,acute myocardial infarction as well as systolic blood pressure were significant risk factors.The efficiency of CI-AKI nomogram was good,and the cutoff value of risk score was-1.953.Conclusion The novel nomogram can be used to preprocedurally predict the risk of CI-AKI after CAG or PCI treatment.
RESUMO
Objective To study and analyze the CT and MRI findings of hepatic eosinophilic infiltration. Methods Twenty nine patients of hepatic eosinophilic infiltration who were confirmed by biopsy or clinical diagnosis were retrospectively analyzed. All the patients underwent CT and/or MRI scan. Twenty seven cases underwent upper abdominal CT plain scan and three phase enhanced scan, and 5 cases underwent upper abdominal MR plain scan and three phase enhanced scan, of which 3 cases underwent CT and MRI scan. Evaluations were made regarding to the numbers of lesion, distribution, size, shape, margin, density or signal characteristic, enhancement parttern and other special features. Pearson correlation analysis was used to analyze the correlation between the number of hepatic lesions and the number of eosinophils in peripheral blood. Results A total of 108 lesions of eosinophilic hepatic infiltration were observed in 29 cases, including 2 cases with single lesion and 27 cases with multiple lesions. Ninety five of the lesions were located in subcapsular parenchyma or surrounding the portal vein. Most subcapsular lesions were wedge-shaped(n=28). Lesions surrounding portal vein were round-shaped(n=32), while the hepatic parenchymal lesions were irregular or round-shaped(n=13). The mean size of lesion was 34 mm, ranging from 3 to 61 mm. The margin of all the lesions were obscure. The lesions showed slightly low density or isodensity on CT pre-contrast images. On MR pre-contrast images, lesions showed slightly low signal or isointense on T1WI, and hyperintense on T2WI. Branches of portal vein were found infilrated by all lesions. Tueleve cases showed“stripe sign”along the portal vein branches, 16 cases showed“halo ring sign”around the portal vein. Pearson analysis indicated a significant correlation between the number of eosinophilic hepatic infiltrated lesions and the increase of eosinophils in peripheral blood (r=0.783, P<0.05). Conclusion The imaging features of EHI had certain characteristics, especially in the three phase dynamic enhanced scanning, from which we can mainly find“progressive enhancement”,“portal vein sign”,“stripe sign”and“halo ring sign”.
RESUMO
Objective To investigate the effectiveness of glucocorticoids in the treatment of granulomatous lobular mastitis (GLM), and to discuss the optimal stage to add glucocorticoids during the treatment. Methods Twenty-four patients having received the core needle biopsy were involved. Ten cases with the explicit pathological diagnosis received the glucocorticoids therapy following the subtotal excision after remission. Pathological diagnoses of the rest 14 patients were undefined. For these 14 patients, simple partial excisions were given and the postoperative pathological diagnoses were presented as the GLM. Of all the 14 patients who accepted the surgical treatment firstly, 8 patients received the postoperative glucocorticoids adjuvant therapy. For the rest 6 patients, steroid hormone therapy was not used after surgery, and they were followed up postoperatively. All patients' clinical and pathological information were collected and analyzed. Results All patients were followed up for 6-36 months (average 18) by the outpatient service. Of all the 10 patients who received the glucocorticoids therapy before surgery, only 1 patient of them got the GLM recurrence. For the 8 patients who received the postoperative glucocorticoids treatment, only 1 patient got the recurrence. For the 6 patients who received simple partial excision, the recurrence of the GLM may be up to 3. There was no statistical difference between the two groups who both received the 05). But compared with the pure surgery treatment, the difference was obviously (P<0.05). Conclusions The clinical presentation and imaging performance of GLM are unspecific, so the diagnosis of the GLM is difficult. There is no consensus regarding the optimal treatment for GLM. The glucocorticoids therapy may be necessary preoperatively or postoperatively. For the patient with clear preoperative biopsy diagnosis, preoperative glucocorticoids adjuvant chemotherapy followed by the wide excision may be an effective method.

RESUMO
BACKGROUND: The effective chemical constituents and the precise action mechanism of Cassia obtusifolia L. seed to rats with hypercholesterolemia are not clear. OBJECTIVE: To investigate effects of anthraquinones from Cassia obtusifolia L. on hypolipidemic activity and endogenous cholesterol biosynthesis in rats with experimental hyperlipoidemia, and to explore the effective compound and the mechanism of Cassia obtusifolia L. seed on hypolipidemic action. DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed from September 2003 to May 2004. All rats were raised and tested at the College of Life Sciences, South China Normal University. Blood sample was collected from the tail vein at the Institute of Biotechnology to detect blood lipid, survival rate, and to culture cells. MATERIALS: Forty-five male Sprague Dawley (SD) rats were used to establish animal models of hypedipoidemia by intragastrically with fat emulsion. Cassia obtusifolia L. seed was purchased from Guangzhou Dispensary, China, and further identified by South China Plant Institute. Anthraquinones were extracted from Cassia obtusifolia L. by the Institute of Biotechnology of South China Normal University. METHODS: Forty-five male SD rats were randomly divided into three groups (n=15): a control group, 80 mg/kg and 20 mg/kg anthraquinones groups. Rat models in each group were given fat emulsion in the morning and afternoon 2 days after model induction, once in morning. Rat modes were treated with corresponding doses of drugs in the two experimental groups. Rat models were administrated with the same volume of saline in the control group, once a day, for 20 days. MAIN OUTCOME MEASURES: Effect of anthraquinones on endogenous cholesterin in Chinese hamster oocytes was measured by amphotericin B cell models. The levels of serum total cholesterol, triglyceride, low-density iipoprotein-cholesterol (LDL-C) and high-density lipoprotein-cholesterol (HDL-C) were detected by enzyme endpoint method. Survival rate of Chinese hamster oocytes (A570) was tested by methyl thiazolyi tetrazolium (MTT) with spectrophotometric determination. RESULTS: Anthraquinones significantly reduced total cholesterol, triglyceride, LDL-C levels and increased HDL-C levels in hyperlipidemic rats in a dose-dependant pattern. Anthraquinones elevated the survival rate of Chinese hamster oocytes. CONCLUSION: Anthraquinones can decrease blood lipid levels. Inhibition of cholesterol synthesis of anthraquinones may be one of the underlying mechanism involved in decreasing blood lipid.
