1.The Effects of Antagonist of Angiotensin II Receptors on Rat Acute Pancreatitis
Journal of Chinese Physician 2001;0(01):-
Objective To explore the effects of antagonist of angiotensin II(Ang II) receptors on acute pancreatitis(AP) of rats. Methods The Sprague-Dawley rats were divided randomly into normal group, AP group, AP+lower dose of valsartan(5mg/kg) group , AP+higher dose of valsartan(8mg/kg) group, lower dose of valsartan group and higher dose of valsartan group, and each group containing 6 animals. AP animal models were induced by intraperitoneal injection of cerulein. Valsartan was given by intragastric administration. The histopathological changes of pancreas were observed and scored, and the pancreatic edema was evaluated. The levels of plasma amylase (AMY) and pancreatic myeloperoxidase (MPO) were measured. Results Compared with AP group, the pathologic lesions of pancreas and pancreatic edema decreased in the group AP+ valsartan, and the levels of plasma AMY and MPO also reduced. Conclusion Pretreatment with antagonist of angiotensin II receptors in rat acute pancreatitis can markedly reduce pancreatic injury and inflammation.

To investigate the relationship between diabetic macular edema (DME) and serum E-selectin level.
●METHODS: Totally 90 patients with diabetic retinopathy in our hospital from October 2009 to October 2013 were observed. Retrospective analysis of the correlation between macular edema degree and serum soluble E -selectin ( sE - sel ). Ninety patients with diabetic retinopathy were divided into two groups: DME group and non - DME group. The level of sE - sel and microalbuminuria (MA) of two groups were determined and compared.
●RESULTS: There was significant difference in MA, sE-sel levels of groups ( P < 0. 05). The value of diabetic retinopathy patients with sE - sel and MA, FBG were positively correlated ( r = 0. 728, P < 0. 05; r = 0. 651, P <0. 05).
●CONCLUSlON: Elevated levels of sE-sel is a risk factor for diabetic macular edema, and sE-sel was involved in the pathogenesis of diabetic microangiopathy.

Objective To study the relationship between the microvessel damage and the death rate of tumor cells and determine role of microvessel damage in the tumoricidal effect of hyperthermia.Methods H22 hepatoma cells were inoculated in the right hind legs of KM mice with immunosuppression.Local hyperthermia was administered to these mice which were divided randomly into 10 groups (8 in each group),which included groups of 3,6,12,24,48,72 and 96 h after hyperthermia for 30 min and groups of hyperthermia for 15,30 and 45 min.The tumor tissues were analyzed by flow cytometry(FCM)and immunohistochemistry.The cultured H22 cells were also given hyperthermia for 15,30,45 min and analyzed by FCM.Results The apoptotic rate(0.115±0.008)was higher in the initiation phase of hyperthermia in vitro,then the necrotic rates rose gradually.The difference between in vivo and in vitro was significant in hyperthermia of the same time about death rate(P<0.05).A strong positive linear correlation(r=0.844)was observed between the death rate of tumor cells and MVD.Conclusion Microvessel damage plays the cardinal role in tumoricidal effect of hyperthermia.

Objective To explore the application of experienced teaching method in the teaching of Fundamentals of Nursing.Methods The feasibility and validity of experienced teaching method was evaluated by expounding the utilization and result of role-play method and practice experienced method.Results The experienced teaching method received good result and proved appropriate in the teaching of Fundamentals of Nursing.Conclusion The experienced teaching method overcame the disadvantages of mere traditional teaching method and aimed at the improvement of quality and ability of students.It contributed to developing the critical thinking ability and other abilities of students.
6.Expression of TGF-βRⅡ and fibronectin in developing mouse kidney
Acta Anatomica Sinica 2010;41(2):281-284
ObjectiveTo observe the chronological and spatial expressions of transforming growth factor-β receptor typeⅡ(TGF-βRⅡ)and fibronectin (Fn )in developing mouse kidney and investigate the relationship between the expressions and kidney development. Methods Immunohistochemistry and Western blotting were used to observe and measure the expression of TGF-βRⅡ and Fn in embryos and postnatal mouse kidneys. Results The expression of TGF-βRⅡ was noticed in all stages of glomeruli, renal tubes and collecting ducts, and increased gradually with ages; The expression of Fn was noticed too in all stages of glomeruli, renal tubes and collecting ducts, except for the comma-shaped bodies, and also increased gradually with ages. Conclusion TGF-β and Fn might play an important role in the development and maturation of mouse kidney.

Metastasis to liver is the most happened distant metastasis and is the leading cause of death in patients with colorectal cancer.Complete surgical resection of liver metastases from colorectal cancer is major curative method for resectable metasrases.Other methods such as chemotherapy, targeted therapy, hepatic ar-tery intervention, radiotherapy, radiofrequenly ablation or cryo-ablation should be considered.Both systemic and local treatment are.important for liver metastasis from colorectal cancer.

Objective To investigate the clinicopathological features,immunophenotype,diagnosis and differential diagnosis of oncocytic mucoepidermoid carcinoma(OMEC).Methods A case of OMEC was studied for clinicopathological and immunohistochemical features,the available literature on this subject was reviewed as well.Results Magnetic resonance imaging revealed a well-defined mass,measured 1 cm×1 cm,within the right submandibular gland.The patient was underwent the total mass and the right submandibular gland resections.On macroscopic examination,the well-defined tumor was gray-yellowish on cut surface with hard consistence and was sized 1 cm×1 cm×0.8 cm.The uncapsulated tumor was mainly solid with focal microcysts on cut surface.Microscopically,the tumor consisted of nests,sheets,and occasional microcysts of oncocytic cells.Focally,intermediate cells,mucilage cell and epidermoid cell were also present.Immunohistochemically,the oncocytic cells were diffusely and intensely positive for CK(AE1/AE3),EMA and P63.By histochemical staining,the oncocytic cells were positive for PTAH staining,and mucilage cell were positive for PAS staining.Conclusion The OMEC is an exceedingly rare variant of mucoepidermoid carcinoma with a good prognosis and should be differentiated from oncocytoma,oncocytic carcinoma,Warthin's tumor with mucinous metaplasia,pleomorphic adenoma,oncocytic myoepithelioma and myoepithelial carcinoma,et al.
