Objective To determine if nitric oxide(NO)is involved in the protective effect of propefolpretreatment(PP)against ischemia-reperfusion injury(I/R).Methods Eighteen male SD rats weighing 250-350 gwere randomly divided into 3 groups(n=6 each):A normal control;B I/R and C PP+I/R.The animals werekilled by a knock on the head.Hearts were immediately removed and passively perfused in a Langendorff apparatusat 37℃ with oxygenated(95% O_2,5% CO_2)Krebs-Hensleit(KH)solution at 90 cm H_20.In group B and C thehearts were subjected to 35 min global ischemia by suspension of perfusion followed by 120 min reperfusion.Ingroup C the hearts were perfused with KH solution containing 50 ?mol?L~(-1) propofol for 10 min followed by 10 minpropefol wash-out before I/R.At the end of reperfusion myocardial specimen was obtained from left ventricle andhomogenized for determination of the activities of total NOS(iNOS+cNOS)aand SOD and expression of iNOS andheme-oxygenase-1(HO-1)and content of NO,The relationship between the NO content and activity and/orexpression of these protein and enzyme were analyzed by correlation analysis.Myocardium was examined with lightand electron microscope.Results The myocardial NO content,tNOS activity and tSOD activity were significantlylower in group B than in group A and C and there was no significant difference in NO content,and activity of tNOSand tSOD between group A and C.The NO content was positively correlated with tNOS and negatively correlatedwith Mn-SOD aetivety and HO-1 expression.Microscopic examination showed severe cell injury or necrosis in groupB but little injury in group C.Conclusion Ischemia and reperfusion decrease activity of tNOS and SOD butincrease HO-1 expression resulting in decrease in NO content.Propofol pretreatment protects the heart from I/Rinjury through increase in NOS and antioxidases(Mn-SOD,HO-1).

[Objective] To investigate the role SPAG5 play in ovarian adenocarcinoma cell mitosis,Taxol sensitivity and ovarian high grade serous carcinoma patients' prognosis.[Methods] Transient knockdown of SPAG5 in SKOV3 cell were performed,and MTT assay and cell cycle flow cytometry assay were carried out.IHC staining of SPAG5 protein in 110 high grade serous carcinoma patients' tumor tissues were performed,and the expression were analyzed with clinical data and prognosis.Finally,SPAG5 were knocked down in OVCAR3 A2780 and SKOV3 cells followed by 0.5μM Taxol treatment,MTT assay were performed to detect cell viability.[Results] SPAG5 knockdown inhibited cell mitosis of ovarian adenocarcinoma cell SKOV3 by G2/M arrest.High grade serous carcinoma patients after neoadjuvant chemotherapy gained the expression of SPAG5.Patients without neoadjuvant chemotherapy with low SPAG5 expression have poor progress free survival,especially in early stage patients.Patients with low SPAG5 expression also have poorer overall survival,but the difference was not statistically significant.Furthermore,SPAG5 knockdown in OVCAR3 A2780 and SKOV3 cells reduced Taxol sensitivity.[Conclusion] SPAG5 regulated cell mitosis and promoted cell proliferation in ovarian adenocarcinoma cell lines.Expression of SPAG5 in patients' tumor tissues predicted patients' prognosis and Taxol sensitivity.As the results,individualized treatment of high grade serous carcinoma patients is necessary.

Objective To explore the hurt of susceptibility organs and critical orgens followed by rotavirus (RV) infection of whole body in newborn mouse.Methods RV strain was derived from the stool samples of patients with RV diarrhea and was proved to be long type by methods of ELISA and polyacrylamide gel electrophoresis (PAGE). RV was inoculated by the pathways of taking orally and injected to abdominal cavities,respectively. The pathological changes of the newborn mouse model infected with human natural RV by light microscope and electron microscope. The gene probe was marked by digoxin.The direct prove of RV infection in these organs was got by the detection of in situ PCR. Results Pathological changes were found in the small intestinal villus,lamina propria of the stomach and the heart cells of the mice taken RV orally.The mice with intraabdominal RV injection showed pathological changes of the cells in the small intestinal villus,liver and kidneys observed by electron microscope.Shortened small intestinal villus,nuclear membrane disorganization,massive vacuolization,mitochondrial swelling and rough endoplasmic reticulum dilation were observed in the cells of small intestinal.In the liver of the mice,marked mitochondrial swelling and agglutination,cell nucleus pyknosis or collapse,presence of numerous lipid droplets and vacuoles were found in the li-ver cells,with lymphocyte and plasmacyte infiltration.Obvious dilatation and shedding of the microvillus were found in cholangioles.The mitochondria of the proximal convoluted renal tubule showed mild swelling,but the cells in the heart and lung did not display obvious changes.Conclusion RV can damage lots of extra intestinal organs of the newborn mice if RV diffuses to the whole body of the mice.

A 77-year-old man was admitted to our hospital at July 5th,2010 with an unexplained massive pericardial effusion for 10 years.With dyspnea for one month and normal vital signs without pulsus paradoxus,other physical examination included a small amount of moist rale,normal heart sounds,jugular vein engorgement,positive hepatojugular reflux,hepatosplenomegaly and pitting edema of the extremities.The patient had a complex past history with lymph node tuberculosis,primary artertial hypertension,polycythernia vera,chronic renal insufficiency and hypothyroidism (Hashimoto's thyroiditis),and moreover,received a high dose radiation of 31p in 1967. Family history is negative.The patient had no cardiac tamponade or pericardial constriction during 10 years,he received pericardiocentesis twice,and pericardial effusion was exudative with a high proportion of monocyte.There was no evidences of tuberculosis infection,hypothyroidism,malignant tumor,severe heart failure,uremia,trauma,severe bacterial or fungus infection,chronic myeloid leukemia or bone marrow fibrosis during the admission. The patient refused anti tuberculosis,indwelling catheter drainage or surgical therapy.In this rare case,the aetiology of chronic massive pericardial effusion is most probably chronic idiopathic recurrent pericarditis.

Objective To investigate the expression and clinical significance of lipoxin A4,leukotrienc C4,lipoxygenase-5 in peripheral blood of pregnant women with different types of severe preeclampsia.Methods Forty-five singleton pregnant women who accepted antenatal care and delivered in First Affiliated Hospital of Wenzhou Medical College were enrolled in this study from December 2010 to June 2011.All objects were divided into normal pregnancy group (n=20),early onset severe preeclampsia group (n=10) and late onset severe preeclampsia group (n=15).Enzymelinked immunosorbent assay was used to detect lipoxin A4 and leukotriene C4 levels in peripheral blood.The level of lipoxygenase-5 mRNA in white blood cells was detected by real time fluorescence quantitative reverse transcription-polymerase chain reaction.The differences of lipoxin A4,leukotriene C4 and lipoxygenase-5 mRNA among groups were compared by analysis of variance and LSD-t test;and correlations among their expressions were analyzed by linear regression.Results Lipoxin A4 level in early and late onset severe preeclampsia group was (355.3±116.0) pg/ml and (389.7±117.5) pg/ml,which were both significantly lower than that in normal pregnancy group [(555.0±139.8) pg/ml] (t=-4.03 and-3.77,P＜0.05 respectively).The leukotriene C4 level in early and lateonset severe preeclampsia and normal pregnaney group was (591.3±185.5) pg/ml,(510.3±197.1) pg/ml and (496.9 ± 158.8) pg/ml,no statistical difference were found (F=0.889,P＞0.05) ; neither did the expression of lipoxygenase 5 mRNA,which was 4.2± 1.9 in normal pregnancy group,4.8 ± 2.0 in early onset severe preeclampsia group and 4.4 ± 1.2 in late onset severe preeclampsia group (F=0.311,P＞0.05).There was no correlation among the levels of lipoxin A4,leukotriene C4 and lipoxygenase-5 mRNA in each group (P ＞ 0.05).Conclusions Early and remarkable decreasing of lipoxin A4 level might contribute to the development of early onset severe preeclampsia.
