Objective To describe the CT characterization of retroperitoneal neuroganglionic tumor in order to get a better understanding of the disease. Methods Neuroganglionic tumors proved by operation and pathology (24 cases), as well as bone biopsy (2 cases), were studied in 18 males and 8 females. The mean age of neuroblastoma(14 cases), ganglioneuroblastoma(10 cases), and ganglioneuroma (2 cases) was 1 year 3 months, 3 years 6 months, and 6 years, respectively. Two cases of ganglioneuroma were complicated with leukemia and malignant pheochromocytoma. All cases were examined by CT scanning and 14 of them had contrast enhancement scanning preoperatively. 20 cases were also examined by ultrasound. Results The tumor sizes were 2.0 cm?2.5 cm?2.5 cm～16 cm?10 cm?8 cm. The tumors were all located in the retroperitoneal space, 22 cases were unilateral, 3 were situated in mid line prelumboscrally, and 1 was bilaterally located. The tumor were irregular in 20 cases and round shape in 6 cases; the tumor margin showed distinct in 14 cases and indistinct in 12 cases. Twenty five tumors showed mixture density and isointensity comparing with the kidney, 1 case with homogeneouse low density; 12 of 14 cases were enhanced inhomogeneously and 2 did not enhance; 23 of 26 cases showed different shapes of calcification. Retroperitoneal lymph nodes were swelling in 19 cases. Liver metastases were found in 3 cases, vascular encasement in 18 cases, tumor thrombus in inferior vena cava in 1 case,and tumor extending into spinal canal in 3 cases. Conclusion CT scanning can prompt the diagnosis of retroperitoneal neuroganglionic tumor and bolus injection of contrast medium can further increase the understanding of the abnormality within and around the tumor.

Objective:To observe the effect of Weijinkang Oral Liquid on rats'models with siliconic nodules and the diffuse fibrosis of the lungs.Methods:45 rats were randomly divided into the blank group,dust-affected group,and treatment group.The rats in the blank group were fed in normal environment.The rats in the dust-affected group were given regular feed.The dust-affected rats in the treatment group were administrated 1.0mL/100g of Weijinkang condensed liquid in 30% by stomach perfusion,two times daily(33 times of human's dosage).Five of each group were killed and anatomized in turn on the 15th day,the 30th and the 90th day.Results:On the 90th day the pathological test showed massive cartilaginous changes projecting to the pulmonary surface in the dust-affected group.There was no abnormality of lungs in both treatment group and blank group.After receiving Weijinkang Oral Liquid the rats in the treatment group showed greater weights than those in the dust-affected group,and the weights of fresh and dehydrated lungs were lighter than those in dust-affected group.Conclusion:Weijinkang Oral Liquid had certain effect on siliconic nodules and the diffuse fibrosis of the lungs caused by pneumonoconiosis.

Objective To investigate the dynamic change of serum high sensitive C-reactive protein (hsCRP) after carotid artery stenting (CAS) and its correlation with in-stent restenosis.Methods The serum hsCRP levels were determined before procedure,at 12 hours,7 days,3 and 6 months after procedure in patients who underwent CAS in the Department of Neurology,Jinling Hospital,Nanjing Their cerebral angiography was reexamined and whether there was in-stent restenosis after 6 months was observed.Results Eighty-four patients treated with CAS were included in the study.Fifteen (24％) had in-stent restenosis after CAS.The stenosis in 3 of them was ＞ 50％,and the stenosis m 12 of them was 30％ to 50％.The serum hs-CRP levels in all patients after procedure were significantly higher than those before treatment (all P ＜ 0.01 ),and they were significantly lower at 6 months after procedure than before treatment (all P ＜0.01).Univariate analysis showed that the proportion of diabetes in the restenosis group was significantly higher than that in the non-restenosis group (P＜0.01).At 7 days (8.83 ± 1.94 mg/L vs.6.77 ± 1.63 mg/L,t =14.398,P=0.044),3 months after procedure (8.26 ± 1.32 mg/L vs.4.58 ± 1.45 mg/L,t =17.569,P =0.008) and 6 months after procedure (7.04 ± i.07 mg/L vs.3.12 ± 1.28 mg/L,t =21.867,P =0.003),the serum hs-CRP levels in the restenosis group were significantly higher than those in the non-restenosis group,and the difference of the serum hs-CRP level (△ hs-CRP) before procedure and at 6 month after procedure was significantly lower than that in the nonrestenosis group (0.85 ± 0.13 mg/L vs.4.89 ± 0.94 mg/L,t =16.987,P =0.000).Multivariate logistic regression analysis showed that /hs-CRP (odds ratio [ OR] 2.392,95％ confidence interval [ CI] 1.538 -3.513; P =0.009) and diabetes (OR 1.840,95％ CI 1.372 -2.241; P =0.023) were the risk factors for instent restenosis.Conclusions The serum hs-CRP level increased significantly at 12 hours after CAS procedure,and then decreased continuously.At 6 months after procedure,the more decrease of the serum hs-CRP level,the lower risk of occurring in-stent restenosis was.

The effect of the autonomic nerves on the transmural dispersion of ventricular repolarization (TDR) under acute myocardial ischemia in intact canine was investigated. Using the monophasic action potential (MAP) recording technique, MAPs of the epicardium (Epi), mid-myocardium (Mid) and endocardium (Endo) were recorded simultaneously by specially designed plunge-needle electrodes at the left ventricular free wall under acute myocardial ischemia in 12 open-chest dogs. MAPD90 and TDR among three myocardial layers as well as the incidence of the early afterdepolarization (EAD) before autonomic nervous stimulation and during autonomic nervous stimulation were compared. It was found that 10 min after acute myocardial ischemia, TDR was increased from 55 +/- 8 ms to 86 +/- 15 ms during sympathetic stimulation (P < 0.01). The TDR (53 +/- 9 ms) during parasympathetic stimulation was not significantly different from that of the control (55 +/- 8 ms) (P > 0.05). The EAD was elicited in the Mid of 2 dogs (16%) 10 min after acute myocardial ischemia, but the EAD were elicited in the Mid of 7 dogs (58%) during sympathetic stimulation (P < 0.01). It was concluded that: (1) Sympathetic stimulation can increase the transmural dispersion of repolarization and induce early afterdepolarizations in the Mid under acute myocardial ischemia, which provide the opportunity for the ventricular arrhythmia developing; (2) Parasympathetic stimulation has no significant effect on the transmural dispersion of repolarization under myocardial ischemia.

The effect of the autonomic nerves on the transmural dispersion of ventricular repolarization in intact canine was investigated. By using the monophasic action potential (MAP) recording technique, monophasic action potentials (MAPs) of the epicardium (Epi), midmyocardium (Mid) and endocardium (Endo) were recorded simultaneously by specially designed plunge-needle electrodes at the left ventricular free wall in 12 open-chest dogs. MAPD90 and transmural dispersion of repolarization among three myocardial layers as well as the incidence of the EAD before autonomic nervous stimulation and during autonomic nervous stimulation were compared. The results showed that the MAPD90 of Epi, Mid and Endo before autonomic nervous stimulation were 278 +/- 11 ms, 316 +/- 16 ms and 270 +/- 12 ms respectively, the MAPD90 of Mid was significantly longer than that of Epi or Endo (P<0.01). MAPD90 of Epi, Mid and Endo were shortened by 19 +/- 4 ms, 45 +/- 6 ms, 18 +/- 3 ms respectively during sympathetic stimulation. Compared with that of the control, the transmural dispersion of repolarization during sympathetic stimulation was shortened from 44 +/- 4 ms to 15 +/- 3 ms (P<0.01), but early afterdepolarizations were elicited in the Mid of 5 dogs (41%) during sympathetic stimulation. Parasympathetic stimulation did not significantly affect the MAPD90 in the three layers. It is concluded that there is the transmural dispersion of ventricular repolarization in intact canine. Sympathetic stimulation can reduce transmural dispersion of repolarization, but it can produce early afterdepolarizations in the Mid. Parasympathetic stimulation does not significantly affect the transmural dispersion of ventricular repolarization.
