Objective To study the apoptosis of endothelial cells and the relation between it and the expression of P53 protein after focal cerebral ischemia reperfusion in rats.Methods The apoptosis of endothelial cell 2,6,12 h and 1,2,3,7,14,21 d after cerebral ischemic reperfusion were observed using an in situ end labeling method,and the expression of P53 protein was detected by immunohistochemical staining methods.Results Apoptotic endothelial cells in ischemic penumbra were observed 2h after cerebral ischemic reperfusion, they peaked at 12~24 h, and decreased gradually.There was no remarkable difference between it and the sham operative group at 21 d.The P53 protein began to express 6h after cerebral ischemic reperfusion, it peaked at 1~2 d, and then declined gradually to controlled level at 7d. The expression peak time of P53 was 24 h later than that of cell apoptosis.Conclusion Apoptosis was a pattern of endothelial cell death after reperfusion of MCAO. P53 protein played an important role in the process of apoptosis of endothelial cells.

Objective To investigate the regulating effects and mechanism of Laminaria japonica (L.japonica) on serum lipid of hyperlipidemia rats.Methods Forty healthy female Wistar rats were used to establish hyperlipidemia models by feeding fat-rich forage,and the powder of L.japonica was applied as a supplement in forage for test groups.The levels of serum lipid including the triglyceride(TG),total cholesterol(TC),low-density lipoprotein (LDL),high-density lipoprotein(HDL) and the activities of lipoproteinesterase(LPL) and hepatic lipase(HL) were detected by biochemical assay.Results The levels of serum TG and TC in test group decreased significantly than those in pre-treated and model group (P

Objective To analyze the imaging features of mycobacterium in AIDSpatients.Methods Twenty-three cases of mycobacterium tuberculosis and 13 patients of non-tuberculous mycobacteria were proved etiologically and included in this study.All patients underwent X-ray and CT examinations,imaging data were analyzed and compared.Results The imaging findings of mycobacterium tuberculosis in AIDS patients included consolidation (n =11),pleural effusion (n =11),mediastinal lymphadenopathy (n =11).Pulmonary lesions were always diffuse distribution,and 14 patients of extrapulmonary tuberculosis were found.Pulmonary lesions in non-tuberculous mycobacteria tend to be circumscribed.Conclusions Non-tuberculous mycobacterial infection in AIDS patients is more common and usually combined with other infections.Imaging features are atypical.

Aim To explore the effect of picrodideⅡ on the expressions of Caspase-3 and poly ADP-ribose polymerase (PARP) in brain tissue following cerebral ischemic reperfusion injury in rats.Methods The middle cerebral artery occlusion reperfusion models were established with intraluminal thread methods in rats. PicrodideⅡ (10 mg·kg~(-1)) and salvianic acid A sodium (10 mg·kg~(-1)) were injected from tail vein for treatment. The neurological function was evaluated with Bederson's test and the cerebral infarction volume was observed with tetrazolium chloride (TTC) staining.The brain structure was observed by hematoxylin-eosin (HE) staining and the apoptosis was counted by TUNEL immunofluorescence assay. The expressions of Caspase-3 and PARP were detected with immunohistochemical and enzyme linked immunosorbent assay.Results After ischemia 2 h and reperfusion 22 h, the rats showed neurological function deficit and cerebral infarction in ischemic hemisphere. The expressions of Caspase-3 and PARP and the number of apoptotic cells in brain tissue increased compared with those in the sham operative group (P <0.05). In picroside and salvianic acid A sodium groups, the Bederson's scores and cerebral infarction volume, the expressions of Caspase-3 and PARP and the number of apoptosis cells were lower than those in the negative control group (P <0.05). While there was no significant difference in five indexes metioned above between picroside group and salvianic acid A sodium group (P >0.05).Conclusion PicrosideⅡ might reduce the expressions of Caspase-3 and PARP to inhibit the neuronal apoptosis induced by cerebral ischemia reperfusion injury and improve the neurological function of rats.

Aim To study the interfering effects of picrosideⅡ on the expressions of nuclear transcription factor kappaB(NF-κB)and inhibitor of NF-κB(I-κB)after cerebral ischemic reperfusion in rats.Methods Intraluminal thread methods were applied to establish the middle cerebral artery occlusion reperfusion models in rats.PicrosideⅡ(10 mg·kg~(-1))and salvianic acid A sodium(10 mg·kg~(-1))were injected from the tail vein for treatment.TUNEL positive cells were counted by immunofluorescence assay.The expressions of NF-κB and I-κB were determined by immunohistochemical assay,and the concentration of NF-κB and I-κB in brain tissue was determined by ELISA.Results The exprssions of NF-κB and I-κB were weakly and the apoptotic cells were scattering at cortex,striatum and hippocampus in the sham operative group.In the negative control group,the number of TUNEL positive cells and the expressions of NF-κB and I-κB increased,the absorption(A)values and the concentration were significantly higher than those in the sham operative group(P<0.05).While in the positive control and picroside groups,the expressions(A values)and concentration of NF-κB and I-κB and the number of TUNEL positive cells were significantly lower than those in the negative control group(P<0.05).There was no significant difference between the positive control group and picroside group(P>0.05).Conclusion Picroside Ⅱ might downregulate the expressions of NF-κB and I-κB to inhibit neuronal apoptosis induced by inflammation after cerebral ischemia reperfusion injury in rats.

Aim To study the interfering effects of picroside Ⅱ on the expressions of nuclear transcription factor kappaB(NF-?B)and inhibitor of NF-?B(I-?B) after cerebral ischemic reperfusion in rats. Methods Intraluminal thread methods were applied to establish the middle cerebral artery occlusion reperfusion models in rats. PicrosideⅡ(10 mg?kg-1) and salvianic acid A sodium(10 mg?kg-1 ) were injected from the tail vein for treatment. TUNEL positive cells were counted by immunofluorescence assay. The expressions of NF-?B and I-?B were determined by immunohistochemical assay,and the concentration of NF-?B and I-?B in brain tissue was determined by ELISA. Results The exprssions of NF-?B and I-?B were weakly and the apoptotic cells were scattering at cortex,striatum and hip-pocampus in the sham operative group. In the negative control group,the number of TUNEL positive cells and the expressions of NF-?B and I-?B increased,the absorption(A) values and the concentration were significantly higher than those in the sham operative group(P0.05 ). Conclusion Picroside Ⅱ might downregulate the expressions of NF-?B and I-?B to inhibit neuronal apoptosis induced by inflammation after cerebral ischemia reperfusion injury in rats.

Objective To compare the value of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ),sequential organ failure assessment (SOFA) and procalcitonin (PCT) in assessment of severe multiple trauma. Methods A retrospective study was carried out on clinical data of patients with severe multiple trauma who were admitted to ICU from July 1 st 2010 to October 31 st 2011.PCT detection,APECHE Ⅱ and SOFA scoring were routinely performed for all the patients within 24 hours,and were performed again one week later for the patients who were complicated with sepsis within one week.Results The score of APACHE Ⅱ and SOFA in septic shock group was higher than that in severe septic and septic groups (P ＜0.01 ),while PCT level among septic,severe septic and septic shock groups had no statistical difference (P ＞ 0.05).To determine the predicting accuracy of APECHE Ⅱ score,SOFA score and PCT,receiver operating characteristic curve (ROC) was constructed.The areas under the curve (AUC) for APECHE Ⅱ score,SOFA score and PCT in predicting the emergence of sepsis on admission was 0.615,0.663 and 0.160 respectively.AUC for APECHE Ⅱ score,SOFA score and PCT in predicting the occurrence of death among the severe multiple trauma patients on admission was 0.576,0.571 and 0.619 respectively.AUC for APECHE Ⅱ,SOFA and PCT in predicting the death of patients complicated with sepsis at one week after admission was 0.746,0.837 and 0.600 respectively. Conclusions Among the APACHE Ⅱ score,SOFA score and PCT,APACHE Ⅱ and SOFA score are better than PCT in assessing the infection severity of sepsis.SOFA score is the best in predicting the occurrence of sepsis,while PCT is the worst.PCT is the best in predicting the occurrence of death of severe multiple trauma patients,while SOFA score is the worst.SOFA score is better than APACHE Ⅱ score and PCT in predicting the occurrence of death of the patients complicated with sepsis.

This paper elaborated the research progress on transduction mechanisms of obese polycystic ovary syndrome (PCOS) and insulin resistance (IR). The action mechanisms of kidney-tonifying, spleen-invigorating and phlegm-resolving in the treatment of obese PCOS and IR were explored. It provided new ideas for the treatment of obese PCOS patients in the clinical practice of traditional Chinese medicine (TCM) gynecology. Literatures on TCM theories and modern signal pathways were used in the analysis of spleen-kidney deficiency and phlegm-dampness retention, which were the key pathogenesis of obese PCOS and IR. The scientific nature of treating obese PCOS and IR from the method of kidney-tonifying, spleen-invigorating and phlegm-resolving was demonstrated. The results showed that the scientific nature of treating obese PCOS and IR from the method of kidney-tonifying, spleen-invigorating and phlegm-resolving was initially demonstrated by the organic combination of TCM and modern medicine theories. It innovatively proposed that the treatment study strategy of transduction molecular mechanism took the interactive dialogue between PI-3K/Akt signal pathway and TNF-α signal pathway as its target. The regulatory role and action mechanism of this method in the treatment of obese PCOS and IR were discussed.
