It was considered that the content of Baicalin in Radix decreased with the time of processing and the degree of heating.Conclusions It's known that the difference of baicalin content in different processed products ofscutellaria baicalensis Georgi was conducive tothe rational and scientific process of products.

Objective To study the clinical nursing significance of ECG monitor in primary PCI for AMI patients and the relation of changes in ECG and the reperfusion of infarction related artery.Methods Regressional analysis was made in ECG changes including different types of arrthymia,degree of ST segment regression,and their relation between the reperfusion of infarction related artery before and after interventional therapy in AMI patients.Results In 468 AMI patients,142 patients had ventricular arrhythmia before therapy.After interrentional therapy,285 patients were co-morbid with accelerated ventricular tachycardia,203 patients with transient ventricular tachycardia or R-on-T phenomenon,62 patients with ventricular fibrillation and received asynchronous electriacal cardioversion.Twenty four patients had new onsent of Ⅱ-Ⅲ degree atrio-ventricular block and 45 patients had bradycardia or sinus arrest.The atrio-ventricular blook in 10 patients before PCI disappeared after the operation.There are 301 patients with apparent ST segment regression(ST segment regressed ≥50%,57 patients with partial ST segment regression,and 29 patients without ST segment changes.Conclusion Arrhythmias always accompanied with IRA reperfusion.Careful monitoring of ECG is essential for patients' safety after AMI.Obvious ST segment is observed in sufficient IRA reperfusion.However,poor regression of ST segment as well as haemodynamics disorder and cardiogenic shock is observed in patients with poor reperfusion or subacute occlusion of IRA.

Erythropoietin is a critical growth factor in development of erythrocyte. After binding to its receptor, eryhropoietin produces biological action through consequent activation of intracellular signal transduction systems, including JAK2-STAT5, sos-Ras-MAPK, IRS-2- PI 3-K + and Ca 2+ channel.

Objective To observe the ultrasonographic features of primary female genital system lymphoma and its histopathological characteristics.Methods Sonographic appearances and histopathological characteristics of 14 patients who were pathologically comfirmed as primary female genital system lymphoma were reviewed.Results Fourteen patients underwent ultrasonography and 15 lesions were found,6 cases of which were found in the ovary and cervix separately,3 cases in the uterine body.Among the lesions detected,10 of which respectively represents extremely low echo and homogeneous internal echo,all lymphomas had posterior enhancement.The margins were most frequently circumcribed (13/15),5numbers primary lymphomas of the ovary were mostly elliptical in shape,while 5 numbers of cervix tumors showed the shape of lobular,all of the tumors in the uterine body showed diffuse symmetrical enlargement without disruption of the endometria.Color Doppler imaging showed hypervascularity in most tumors(13/15).The pathological examination showed that all tumors were non-Hodgkin lymphoma diffuse B-cell type.Conclusions Primary female genital system lymphoma has some ultrasonic features,including extremely low echo,homogeneous echo and posterior enhancement.Final diagnosis depends on the histopathology.

Objective To investigate the effect of SKP2 expression on radiation induced bystander effect (RIBE) of esophageal cancer cells.Methods The esophageal cancer cell lines with different SKP2 levels were applied for the study and the SKP2 expression was identified by Western blot.Micronuclei (MN) assay and DNA foci assay were used to evaluate the effect of SKP2 on RIBE.The cells were transfected with SKP2 gene or SKP2 siRNA to further verify the effect of SKP2 on RIBE.Results MN assay showed that the bystander effect induced by the cells with a high level of SKP2 was lower than that induced by the cells with a lower level of SKP2 (t =8.06,P ＜ 0.01).These results were further confirmed by the gene transfection experiments.When the expression of SKP2 was increased,RIBE was decreased (t=11.12,10.16,P ＜ 0.01).Contrarily,when the expression of SKP2 was reduced,RIBE was increased (t =8.39,8.83,P ＜ 0.01).γ-H2AX foci formation assay disclosed that when SKP2 expression in the irradiated cells increased,the repair ability of DNA damage in the bystander cells was higher than the control (t =6.85,7.10,P ＜ 0.01).With the expression of SKP2 decreased,the repair ability of DNA damage was lower than the control (t =7.66,8.47,P ＜ 0.01).Conclusions Over-expression of SKP2 inhibits RIBE of esophageal cancer cells,at least partly through regulating DNA damage repair ability.

Objective To research the chronic respiratory infectious diseases caused by Pseudomonas aeruginosa need to objectively the reflection of the real environment in the body, so established a mouse model of chronic pulmonary infection with Pseudomonas aeruginosa and analyzed it's inflammatory response. Methods Establishment of chronic bronchial infection mice model that were inoculated with Pseudomonos aeruginosa-laden agarose beads, and analyzed its inflammatory response by detected the cytokines and MMP-2, and a differential cell count and a total leukocytes count were performed as well. Results Pseudomonas aeruginosa had been detected after infection, and there were changes in pathological. Pulmonary inflammation appeared in 1 d and reached near baseline levels by 7 d after inoculation. It was verified that the peak of inflammatory reaction in Pseudomonas aeruginosa infection is in 2-3 d; the mice did have detectable levels of circulating matrix metalloproteinase-2 ( MMP-2 ) after infection with Pseudomonas aeruginosa. MMP-2 concentrations in the blood serum peaked at 3 d after inoculation. It is indicated that Pseudomonas aeruginosa can initiate a certain degree of pulmonary fibrosis on the basis of the pulmonary inflammation. Conclusion In this study, chronic bronchial infection animal model affected by Pseudomonas aeruginosa was established successfully. Base on this animal model, we can do the pathogenicity and drug resistance of Pseudomonas aeruginosa further study.

Objective To investigate the MRI features of hepatic IgG4?related inflammatory pseudotumor (IPT). Methods Nine patients with 11 histopathologically proven IgG4?related hepatic IPTs were retrospectively analyzed. The clinical, morphological and MRI signal features on T1WI, T2WI, dynamic?enhanced, and diffusion?weighted imaging were assessed in detail and correlated with pathological findings. The paired t test was used to compare the ADC values of the tumors and the hepatic tissue. Results Hepatic IgG4?related IPT displayed certain MRI features. The dominant lesions were subcapsularly distributed (n=7) with a clear boundary (n=8), which typically showed hypointensity on T1WI (n=11), mild hyperintensity on T2WI (n=8), progressive (n=5) or persistent (n=4) enhancement pattern. Accompanied signs included delayed capsule?like enhancement (n=6) and central nonenhanced areas (n=7). Two lesions showed atypical wash?out pattern with iso or hypointensity on portal and delayed phases. In diffusion weighted imaging, all lesions were hyperintense, and the mean ADC value of the lesions [(1.42 ± 0.36) × 10?3mm2/s] was mildly lower than that of surrounding liver [(1.55±0.31)×10?3mm2/s], although no statistical differences were found(t=0.78, P=0.46). Conclusions Hepatic IgG4?related IPTs display various MRI manifestations. The lesions normally show progressive enhancement pattern with diffuse homogeneous or heterogeneous hyperintensity, accompanied by delayed capsule?like enhancement and central nonenhanced areas.
