Objective To observe the effect on succinate dehydrogenase (SDH) of mitochondria in myocardium and liver in sepsis rats treated with edaravone. Methods 30 Sprague-Dawley rats were divided into 3 groups: sham operated group ( group A ), controlled operated group ( group B ), treated group with edaravone (group C). The model of sepsis rats was made by the way of caecum ligated and punctured and 20mg/kg lactate levofloxacin was subcutaneously injected (sci) 15min before and 3h after operation in three group. 5mg/kg edaravone were sci 15min before and 3h after operation in group C. Liver and myocardium were taken from all of them 18h after operation. The activities of SDH in myocardial and hepatic mitochondria were detected, pathological change of mitochondria in liver and myocardium were observed. Results The activities of SDH in myocardial and hepatic mitochondria in group B [ (0. 21 ± 0. 07 ) U/mgprot, (0. 23± 0. 08 ) U/mgprot ] were significantly decreased compared with group A [ ( 0. 33 ± 0. 10 ) U/mgprot, ( 0. 38±0. 12)U/mgprot]. The activities of those in group C[ (0.31 ±0. 08) U/mgprot, (0. 36 ±0. 11)U/mgprot] were significantly increased than group B. Myocardial and hepatic mitochondria swelling and endocytoplasmic reticulum expanding were found in group B by electron microscope, while it showed normal in group C. Conclusion Hepatic and myocardial mitochondrial structure were destroyed and activities of SDH were decreased in sepsis rats. They could be effectively protected by edaravone.

Objective To observe the change and its clinical significance of serum B-type brain natriuretic peptide (BNP) concentration in patients with acute cerebral hemorrhage. Methods The plasma BNP level was measured by microparticle enzyme immunosorbent assay (MEIA) method in 100 patients with acute cerebral hemorrhage. The blood volume of cerebral hemorrhage was computed respectively. The Glasgow Coma Scale (GCS) and National Institutes of Health Stroke Scale (NIHSS) were used to evaluate nerve function on the 1st, 3rd, 7th and 15th day after admission, and the Glasgow Out-come Scale (GOS) was used when the patient was discharged from hospital or died. Results The plasma BNP level at the 2nd day after admission was positively correlated with the blood volume of cerebral hemorrhage in patients with acute cerebral hemorrhage (r=0.367, P=0.000), with NIHSS score at the 1st, 3rd, 7th and 15th after admission (r=0.491, 0.444, 0.427 and 0.458, all P=0.000), and with GOS score (r=0.507, P=0.000). In addition, it was negatively correlated with GCS score at the 1st, 3rd, 7th and 15th after admission (r=-0.553, -0.429, -0.473 and -0.501, all P=0.000). Conclusions The plasma level of BNP is good for predicting the strike of cerebral hemorrhage patient′s condition, it is likely to provide a original thread for judge the severe degree of patient′s condition.

ObjectiveTo explore the expression and clinical significance of Ras-related C3 botulinum toxin substrate 1 (Rac-1) protein and hypoxia-inducible factor 1α (HIF-1α) in breast cancer and their relationship with tumor stage, node metastasis status and hormone receptor status. MethodsImmunohistochemical method was used to detect the expression of Rac-1 and HIF-1α protein in 139 specimens of breast cancer,combined with their clinical pathological characteristics and hormone receptor status for statistical analysis.Results The expression of Rac-1 and HIF-1α in breast cancer tissue were 64.75 ％ and 65.47 ％,respectively.The levels were related with the stage of TNM and histological grade (P ＜ 0.05,P ＜ 0.01).There was no significant correlation between these two proteins'expression and the age of patient,primary pathological location, histologic type and menstruation status of breast cancer patients(P ＞ 0.05). The expression of Rac-1 and HIF-1α had no statistical significance between triple negative breast cancer(TNBC)and non-triple negative breast cancer (NTNBC) patients (x2 =1.1229,x2 =0.1786,P ＞ 0.05); The expression level of Rac-1 was positively correlated with HIF-1α in these breast cancer specimens (rs =0.414,P ＜ 0.01).ConclusionThe expression of Rac-1 is positively correlated with HIF-1α level in breast cancer.The relationship between Rac-1 and HIF-1α might be as a new important marker to estimate the invasion,metastasis extent and prognosis in breast cancer.Blocking the regulation between Rac-1 and HIF-1α might be a new treatment target in breast cancer.

Background and purpose: Death-associated protein kinase-1(DAPK) is a pro-apoptosis protein,and plays a important role in oncogenesis and development.This study is to investigate the expression of mRNA of DAPK1 and its association with apoptosis in papillary thyroid carcinoma(PTC).Methods:The expression of DAPK1 mRNA was detected by in situ hybridization in 45 cases of PTC and 45 cases of normal thyroid tissues next to tumors that consist of three part of tissue: normal thyroid tissue,nodular goiter and follicular adenoma.The apoptosis in corresponding issues was tested by TUNEL assay and the apoptosis index(AI) was evaluated.Results:The positive rate of DAPK1mRNA in PTC and para-PTC tissues were 37.78% and 71.11%,respectively.The positive rate of DAPK1 mRNA in counterpart thyroid issues was higher than that in tumor tissues(P0.05).Conclusions:As an apoptosis promoter,DAPK1 may function as an inhibitor of tumor,and low expression or loss DAPK1 gene may be involved in the oncogenesis of PTC.The detection of the expression of DAPK1 may be helpful for judging metastasis and prognosis of PTC.

[ABSTRACT]OBJECTIVETo observe the anatomic relationship between the middle and distal section of bony nasolacrimal duct and anterior wall of maxillary sinus. METHODS206 cases of sinus CT without maxillary disorders were enrolled. The middle and distal section of bony nasolacrimal duct and anterior wall of maxillary sinus is divided into fusion type and separation types, and the angle between the anterior and medial wall of the maxillary sinus is divided into frontal and lateral types in relation to the middle and distal section of bony lacrimal duct.RESULTSThe fusion type accounted for 40.05%, and the separate type was 59.95%. There was no statistical difference between male and female.The proportion of inconsistency on both sides was 16.02%. The frontal type of the angle between the anterior and medial wall of the maxillary sinus accounted for 64.08%, meanwhile the proportion of the lateral type was 35.92%. The lateral type was 84.24% out of the cases of fusion type, whereas the frontal type was15.76%. In the separate type, the frontal type accounted for 97.17%, and the lateral type was 2.92%. CONCLUSIONThe anatomic relationship between the middle and distal section of bony nasolacrimal duct and anterior wall of maxillary sinus shows different type, which is helpful to choose operative strategy.

Objective To explore the effect of Kaolin combined with propranolol on matrix metalloproteinase-9 (MMP-9) in lungs of paraquate (PQ) intoxicated mice and the mechanism of protection for lung injury. Methods Fifty-four ICR mice were randomly divided into three groups, 18 mice in each group: namely control group, PQ intoxicated group and treatment group. The PQ intoxicated model was replicated by intra-gastric administration (ig) of PQ 100 mg/kg; after intoxication, 48 g/kg Kaolin combined with 3.2 mg/kg propranolol intra-gastric administration was immediately given to the treatment group, while in the control group, the same volume of normal saline ig was applied. All the mice were sacrificed at 6, 12 and 24 hours after disposal, and the lung was harvested to test the protein expression level of MMP-9 by Western Blot, and the lung tissue pathological changes were observed.Results There was no statistical significance in the protein expression levels of MMP-9 among the control group, PQ intoxicated group and treatment group at 6 hours after disposal (grey value: 0.655±0.045, 0.656±0.045, 0.641±0.036). The protein expression levels of MMP-9 in PQ intoxicated group were increased significantly compared with those in the control group at 12 hours and 24 hours after disposal (12 hours: 0.824±0.039 vs. 0.634±0.038, 24 hours: 0.742±0.039 vs. 0.658±0.041, bothP < 0.05), while the levels of treatment group were significantly lower than those in the intoxicated group (12 hours: 0.760±0.050 vs. 0.824±0.039, 24 hours: 0.686±0.041 vs. 0.742±0.039, bothP < 0.05). In PQ intoxicated group, early capillary dilation and congestion in lung tissue, a large number of inflammatory cells infiltration with mainly neutrophils in alveolar cavity and a small number of red blood cells exudation were seen at 12 hours; at 24 hours, capillary dilation at alveolar walls, congestion, swelling of endothelial cells, small flakes or large patches of inflammatory cell infiltration with mainly neutrophils in lungs were found. In the treatment group, the lung inflammatory cells infiltration, alveolar capillary dilatation, congestion, swelling of the endothelial cells, etc were also visible, but the degree of severity was significantly milder than those in the intoxicated group.Conclusion The interference of Kaolin combined with propranolol can significantly decrease the protein expression level of MMP-9 in lung tissue of acute paraquat poisoned mice that is possibly one of the mechanisms for prevention and treatment of lung injury in paraquat poisoning.
