[ABSTRACT]ObjectiveTo observe the clinicopathologic characteristics of the solidpseudopapillary neoplasm of the pancreas (SPN) and to probe into its differentiation patterns and histogenesis.MethodsThe histological characteristics of 15 cases of SPN were observed by HE method. Immunohistochemical PV 6000 was used to test some protein expression in 15 cases of SPN. ResultsClinical and imageological findings were: all the 15 cases were females, mean age (range) was 27.5 years (18-51). Of the 15 tumors, 5 located in the head of the pancreas, 5 in the body, 4 in the tail and 1 in retroperitoneum. The mean (range) diameter of the tumors was 9.3 cm (3.0-17.3), in which, 14 with intact capsule. CT revealed variable combinations of solid and cystic areas in all 15 cases, in which, 14 had a higherdensity fibrous capsule, no clear margin was seen in one. Followup of from 3 months to 10 years, no recurrence was found, another one with hepatic metastasis 13 months later. Histology showed a uniform population of tumor cells. The nuclei were oval or round without atypia, and mitotic activity was absent. Psudopapillary structure with a fibrovascular core was remarkable. Hemorrhage, foam cells and cholesterol crystals were often found. Immunohistochemically, 15 cases had positive for α1AT, 13 had vimentin, 10 had NSE, 5 had CgA, 8 had PR and 4 had Actin; but ER, Syn, EMA, Glucagon, Gastrin and Insulin were negative for all the cases.ConclusionSPN is most commonly seen in young female with a benign clinical course and a higher surgicallycure rate, which develops from primitive pancreatic cells,with the potentiality of developing into ducts,acinus,and endocrine cells.
胰腺實性假狀瘤(solidpseudopapillary neoplasm of the pancreas,SPN)是一種相當少見的腫瘤。由FRANTZ于1959年首先報道,至1998年國外文獻共報道299例,多見于青年女性,約占胰腺腫瘤的1%[1~3]。SPN的細胞起源、組織發生和生物學行為目前仍不清楚,有待于進一步的探討和觀察。本文通過對15例SPN臨床及影像學資料分析,對蘇木精伊紅(HE)染色切片進行病理觀察以及應用免疫組織化學方法檢測多種蛋白的表達,旨在探討其臨床病理學特點、分化表型及組織起源,為今后SPN的臨床及病理診斷和治療提供依據。

Abstract:Objective To establish chronic obstructive pulmonary disease (COPD) rat models, and to study the intervention of the formula of nourishing Qi, activating blood circulation and dispersing phlegm recipe on the morphology. Method To establish rat COPD models by intratracheal instillation of lipopolysaccharide and exposure to cigarette smoke. To instill intervention drug daily either the formula of nourishing Qi, activating blood circulation and dispersing phlegm recipe or the roxithromythin, starting on the 20th, 30th and 40th day of the experiment respectively (the groups was named h 20, h 30, h 40, r 20, r 30 and r 40 for short), and to observe the effect on the morphology by means of collagen staining and image analyzer. Results The pathological changes and lung function in the model group were accorded with the human COPD. In drug intervention groups, airway inflammation and epithelial proliferation were alleviated to different degree compared to the model group. In model group, the collagen deposition was increased predominant type I collagen compared to the health comtrol group, and the deposition in the drug intervention groups were decreased compared to the model group, according to the Sirius redpolarizing microscopy morphometry method. The thickness of the airway wall in the model group was significantly increased compared to the health control group (P

【Abstract】 Objective To observe the curative effect of PTSMA in 12 HOCM patients in the near future. Methods 12 HOCM patients(8 men,4 women,mean age 38.6±12 years),whose course of disease were 1~10 years. They had all received drug therapy such as β-blockers and/or calcium antagonists with less therapeutic efficacy. After determine the target vessel under RAO 30°~45°,absolute alcohol was injected into the septal branch through the central lumen of balloon catheter. ECG and LVOTG should be observed closely at the same time. Each of them will take an echocardiogram after the procedure and will be followed-up for six months.Results 8 of them were performed in the first septal branch,2 were in the second septal branch,the remaining 2 cases were peformed in both vessels. During the procedure,sinus bradycardia were occurrenced in 3 patients,8 with CRBBB and 6 with PVC frequently,but all of this were temporarily. The cardiac murmur were disappeared completely in 3 cases,9 were attenuated I~II class than before. After the procedure,the echocardiogram showed that the hypertrophic myocardium of ventricular septum was thinner and weaken,and the LOVTG was decreased,the SAM phenomenon was disappeared and the LVEF was increased.Conclusion PTSMA is a new kind of technology,which is using the technique of PTCA ,can cause focal myocardial infarction by injecting the absolute alcohol into the septal branch. In this group,the symptom, physical sign and the appearance of echocardiogram of the 12 patients were significantly improved after the procedure. There won’t any severe complication in this group. It seemd PTSMA is an effective way to treat HOCM,the effect is reliable in the near future,but the prospective efficacy is still need to be observed further more.

The Role of EOS、TGβ1 and IL-4 in the Pathogenesis of Asthmatic Children and Their Clinical Significances
Abstract:Objective: To explore the role of EOS、TGβ1 and IL-4 in the pathogenesis of asthmatic children and their clinical significances. Method: TGβ1 and IL-4 of 60 cases in acute attack group and that of 48 cases in remission group,and that of 30 healthy children in normal control group were detected by Sandwich ELISA.EOS was detected by blood cell analyzer. Result: The serum TGβ1 level was lower in acute attack group than that in remission group. The serum 1IL-4 and EOS were higher in acute attach group than that in remission group. The serum TGβ1 level was lower in risk group than that in ordinary group. The serum IL-4 and EOS were higher in risk attach group than that in ordinary group.Conclusion: EOS、TGβ1 and IL-4 played a role in pathogenesis .There was certain correlation between serum levels of EOS、TGβ1 and IL-4 with serious degree in asthmatic children.
