As the existing electrical field method for colon hollow structure virtual eversion is time consuming, a new faster method is presented here to overcome this disadvantage. In the new method, the cross section we used is composed of an orthogonal section and an electrical field section rather than the electrical field section only. We have applied this new method to a series of CT data of a patient for virtual eversion. The result shows that the time cost by using the fast method is only about 1/6 of the existing method, and the image quality is also acceptable.

Objective To investigate the rationality and safety of dengzhanxixin injection used in elderly inpatients. Methods The clinical data of 986 inpatients including 620 males and 366 females were collected, and questionnaires containing age, sex, discharge diagnosis, symptoms, drug dosage, course of treatment, laboratory examination, adverse drug reaction and drug effect were analyzed. Results For the 986 cases, the average age was(74.3±7.5)years. The average dose of dengzhanxixin injection was (38.2±4.4) ml, once daily by intravenous drip, and the average period of treatment was (10.8±5.2) days. The adverse reaction rate was 0.81%. The levels of blood glucose and hemoglobin were decreased after treatment(t orμ=1226.5,2620.0, both P<0.05), but there were no statistical differences in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CREA), blood urea nitrogen (BUN) and white blood cell count (WBC) before and after treatment (t or μ=122.5, 405.0, 513.5, 996.5, 956.5, all P>0.05). Conclusions It is safe to use dengzhanxixin injection according to the medication description for elderly inpatients.

Objective To explore the CT features of renal epithelioid angiomyolipoma (EAML), and to improve the diagnosis of this disease.Methods The clinical materials and image findings of 15 cases (8 female, 7 male) with renal EAML proved by pathologies were retrospectively studied.Plain and enhancement CT scan were performed in all 15 patients.Nine of the 15 cases were correctly diagnosed and the other were misdiagnosed as renal cell carcinoma (RCC) (n=5), renal oncocytoma (n=1).Results There were some distinctive findings of EAML: (1) Little hypodense or iso-high-density, well defined, round lesion with diameter of 2 to 5 cm.(2) The tumor may involve the medulla of kidney or grow out without haematuria.(3) Most lesions showed obviously uniformity enhancement at artery phase, with a few of them showed inhomogeneous enhancement There were thickening and circuitous vessels in a few lesions.(4) Enhancement mode was quick-in and quick-out.Conclusions CT findings combined with clinical materials have important value in making a correct diagnosis of EAML preoperatively.

Objective　To evaluate the expression of Fas/FasL antigen on peripheral blood T lymphocytes and its possible role in Behcet disease. Methods　The expression of Fas and FasL antigen on peripheral blood T lymphocytes was determined by flow cytometry and three-colour double marked immunofluorescence methods in 26 patients with Behcet disease and 43 healthy individuals. Results　The difference was significant between Behcet disease (25.70%±7.32%) and controls (14.02%±6.30%) concerning the Fas expression on CD4+ T lymphocytes(P＜0.01) . But no difference was found concerning the expression of FasL antigen between Behcet disease and controls (P＞0.05).The expression of Fas antigen on CD8+ T lymphocytes from Behcet disease (9.47%±6.97%)was significantly higher than that in control group(3.47%±2.75%), but no difference was found concerning FasL antigen expression on CD8+ T lymphocytes between Behcet disease and controls(P＞0.05).Conclusion　These results indicate the imbalance of the expression of Fas and FasL on T lymphocytes in Behcet disease is responsible for the perpetuation and recurrence of Behcet disease for the activated lymphocytes would not be eliminated through apoptosis mediated by Fas/FasL system.

OBJECTIVE:To provide reference for vancomycin-induced neutropenia adverse reactions/adverse events in clinical diagnosis. METHODS:With a case of children with neutropenia treated by long-course and large-dose vancomycin,PubMed and CNKI were retrieved to collect related literature and the literature was analyzed. RESULTS:Neutropenia may be associated with vancomycin,based on causality criterion of adverse reaction in China. CONCLUSIONS:Vancomycin-induced neutropenia in chil-dren is most likely associated with prolonged exposure induced by infusion,vancomycin dosage should be reduced or stopped,and routine blood and plasma concentration should be closely monitored.

Objective To investigate the impact of hyper-homocystinemia (Hcy)on cardiac remolding in spontaneously hypertensive rat(SHR)and the protective effects of folic and vitamin B12 on the remolding.Methods The seven-week-old SHR were divided into four groups according to different diet for 20 weeks.The control group was fed a perfect compound diet without methionine,the methionine group was fed a perfect compound diet added with 2 ％ methionine,the treatment group was fed as that of methionine group,but added with vitamin B12 0.09 mg/(kg.d)and folate 4 mg/(kg.d)in the last 12 weeks,the mixture group was fed as that of methionine group in the first 8 weeks,and as that of control group.At the end of the intervention period,plasma levels of Hcy and matrix metalloprotease(MMP)-9 were measured.The blood pressure was detected by the non-invasive blood pressure sensing device.The cardiac structure and function were detected using echocardiography and invasive hemodynamic method.Picro-sirius red(PSR)staining was used to check the fibrosis in paraffin embedding ventricle section.Results Plasma levels of Hcy and MMP-9 were increased in the methionine group,while there was no significant difference in plasma levels of Hcy and MMP-9 among the treatment group,the mixture diet group and control group.Rats in methionine group had the largest heart weight among four groups,and systolic blood pressure was lower in methionine group than in the control group(P＜0.05).Compared with the other three groups,the methionine group showed that the left ventricular end-diastolic pressure(LVEDP)was increased and-dp/dt maxwas decreased.Meanwhile,LVEDP and-dp/dt m,x had no significant difference between the control group,treatment group and mixture group.The methionine group showed the most severe decrease in the left ventricular fractional shortening(LVFS)and +dp/dt While LVFS and + dp/dt max had no statistical significance between the treatment group and control groups,but the mixture group had lower LVFS and +dp/dt max values as compared with the control group(both P＜0.05).Perivascular fibrosis was increased significantly in methionine group as compared with the other three groups,while the treatment and control groups had similar perivascular fibrosis,but the mixture group had higher perivascular fibrosis than did the control group,and had similar perivascular fibrosis to the treatment group.Fibrosis deposition in myocardium mesenchymal was similar to those observed in perivascular fibrosis,but the treatment group showed a more improvement of collagen deposition as compared with the mixture group.Conclusions Hyper-homocystinemia can accelerate systolic and diastolic dysfunction through accumulating fibrosis in myocardium and perivascular wall which lead to adverse cardiac remolding.Folate and vitamin B12 have protective effects on heart function by reversing the adverse changes through decreasing Hcy level.
