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.

Objective:To study the effect of nursing English teaching combining with humanistic care educa-tion. Methods:Six classes of nursing students of 2011 grade were chosen randomly by sampling as control and ex-perimental group. The control group used the traditional teaching method without humanistic care education. The experimental group combined humanistic care education with nursing English teaching. Nursing students' humanistic caring ability scale and self-designed questionnaire were used to compare the teaching effects of the two groups. Results:The humanistic caring ability of experimental group was higher than that of the control group ( P<0 . 05 ) . The experimental group gives high evaluation on the effect of nursing English combining with humanistic care edu-cation. Conclusion:Nursing English combining with humanistic care education helps to improve nursing students' humanistic concern consciousness and enhance their humanistic caring ability.

Objective To study the clinicopathological and immunohistochemical features of squamous cell carcinoma (SCC) of breast.Methods Three cases with breast SCC were studied by analyzing their clinical data,histomorphology and immunophenotype.The related literature was reviewed.Results The patients were all females.Their ages ranged from 37 to 50 years,with 43 years as the medium.The tumor diameter was 2-9 cm,with 4.3 cm as the medium.Metastasis of axillary lymph node was found in one case,accounting for 33％ of the total.Two cases had painless lumps in their left breasts.One case had a lump with local inflammation,pain and ulcer in her left breast.Histopathological examination showed the polygonal and spindle-shaped cells with eosinophilic cytoplasm were found in cancer nest,as well as the prominent intercellular bridges and keratin pearls were found to be rich in three cases.Interstitial fibrosis with hyalinization and lymphocytic infiltrate around the tumor was also found.Immunohistochemistry showed ER,PR,HER-2,CK18 and SMA were negative while CK,CK14,CK5/6,p63,S-100 and vimentin were positive.Conclusions SCC is a rare subtype of breast carcinoma with distinct histopathological and morphological features.SCC is a typical basal-like breast carcinoma,and the majority of breast SCC appear a basal-like immunophenotype with poor prognosis.

Objective To evaluate the value of DNA quantitative analysis in diagnosis of breast tumor.Methods The data of 128 cases diagnosed with breast disease from Feb.2005 to Jan.2006 in Department of Pathology in Wuhan Center Hospital were collected,among whom 72 cases had benign breast lesion,10 cases had boundary breast lesion and 46 cases had malignant breast disease.Automated DNA imaging cytometry was used to identify DNA indexes of the 128 cases.Results The positive rate was 1.39％ (1/72),30.00％ (3/10) and 78.26％ (36/46) respectively in benign breast lesion,boundary breast lesion and malignant breast disease.The difference had statistical significance (P ＜ 0.05).In invasive ductal breast cancer,the positive rate was 57.14％ (4/7),76.47％ (13/17) and 100％ (18/18) respectively for breast cancer of grade Ⅰ,Ⅱ and Ⅲ.Conclusion Automated DNA imaging cytometry is of some value in analyzing the malignant grade of breast cancer and predicting the prognosis of breast diseases.

Objective:Recent studies have shown that in contrast to decrease in distal gastric adenocarcinoma (DGA), incidence of adenocarcinoma of the esophagogastric junction (AEG) has increased noticeably in numerous counties. However, the reasons remain unclear. This study evaluated the possible differences in the expression of KLF4, SP1, and Cyclin D1 in AEG and DGA, and explored the potential carcinogenesis of AEG. Methods:Immunohistochemistry was performed on paraffin-embedded tissues to evaluate the pu-tative differences in the expressions of KLF4, SP1, and Cyclin D1 at protein level between AEG (n=58) and DGA (n=47). The patholog-ical significance of these markers between the two groups was also compared and analyzed. Results:The percentage of positive KLF4 expression was significantly lower in DGA than in AEG (P<0.05). Lower KLF4 expression was found both in well-or moderately dif-ferentiated cases and in poorly differentiated cases with DGA compared with their AEG counterparts (P<0.05). However, positive stain-ing for SP1 was significantly higher in DGA (P<0.05). No significant difference was found in the expression of Cyclin D1 between the two groups. Further analysis showed that in DGA, the positive expression of KLF4, SP1, and Cyclin D1 were significantly correlated with lymph node metastasis. In AEG, only Cyclin D1 expression was correlated with lymph node metastasis (P<0.05). No correlation was found among the expression of KLF4, SP1, and Cyclin D1 in AEG. In DGA, KLF4 was inversely correlated with SP1 and Cyclin D1 (r=-0.334 and r=-0.341, respectively, P<0.05), and SP1 was positively correlated with Cyclin D1 expression (r=0.340, P<0.05).Conclusion:Different expression patterns and clinicopathological significance of KLF4, SP1, and Cyclin D1 were observed between AEG and DGA, suggesting the putative difference in the carcinogenesis and progression of AEG and DGA.

Objective To observe the relationship between plasma level of homocysteine(HCY) and ischemic stroke in young and middle-aged adults,explore the clinical signficance concerning the occurrence and development of ischemic stroke in young and middle-aged adults.Methods The plasma homocysteine level of 132 young and middle-aged adults patients with ischemic and 86 control peoples were measured by means of enzymatic cycling assay.Results The plasma homocysteine level in ischemic stroke was higher than that in control group( P ＜ 0.01 ).The higher the plasma homocysteine level,the larger infarcted focus in acute ischemic stroke group of young and middleaged adults.The plasma homocysteine level and the infarcted focus was positively linearly correlated.Conclusion Hyperhomocysteinemia is a risk factor of ischemic stroke among young and middle-aged adults.The higher the plasma homocysteine level,the larger infarcted focus in acute ischemic stroke group.The plasma homocysteine level can reflect the size of the infarcted focus and the degree of disease,and the plasma homocysteine level should serve as a kind of regular examination or as an index intervention can be taken,all of which are great importance to prevent ischemic stroke and reduce its morbilily.

The reported incidence of synchronous multiple primary cancer (SMPC) is rare, and it is even less common to observe synchronous solid tumor with a hematological malignancy. We report five cases of solid tumor presented synchronously with hematological malignancy, all observed within a 2 year period at the oncology department of a university hospital in Shanghai, China. These individual cases included lung adenocarcinoma with chronic myelogenous leukemia, colon cancer with solitary plasmocytoma, gastric adenocarcinoma with diffuse large B cell non-Hodgkin's lymphoma, lung adenocarcinoma with multiple myeloma, and colon cancer with diffuse large B cell non-Hodgkin's lymphoma. It is challenging to therapeutically control the biological behavior of concurrent multiple primary tumors, and there is no standard treatment for such rare conditions. In this paper we discuss these five cases of SMPC and their treatments.

Objective To investigate the role and mechanism of action of Scabiosa atropurea in inhibiting the proliferation of hepatic stellate cells using cell experiment. Methods A total of 20 Wistar rats were randomly divided into control group and administration group, with 10 rats in each group. The rats in the control group were given normal saline by gavage, and those in the administration group were given Scabiosa atropurea by gavage to prepare drug-containing serum. HSC-T6 cells were incubated with the serum from the control group (10%) or the low-, middle-, and high-dose serum containing Scabiosa atropurea (10%, 15%, and 20%, respectively). MTT assay was used to observe the effect of different drug concentrations on cells in different periods of time; flow cytometry was used to measure cell apoptosis; qRT-PCR and Western blot were used to measure the mRNA and protein expression levels of fibrosis markers (α-SMA, collagen Ⅰ) and PI3K/Akt signaling pathway-related factors in hepatic stellate cells (HSCs). A one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t - test was used for further comparison between two groups. Results Compared with the control group, the low-, middle-, and high-dose serum containing Scabiosa atropurea groups had a significant reduction in the OD value of cells (all P < 0.05) and a significant increase in the overall apoptosis rate of cells (all P < 0.05). The results of qRT-PCR showed that compared with the control group, the low-, middle-, and high-dose serum containing Scabiosa atropurea groups had significant reductions in the mRNA expression levels of α-SMA, collagen Ⅰ, PI3K, and Akt and a significant increase in the mRNA expression level of PTEN (all P < 0.05); Western blot showed that compared with the control group, the low-, middle-, and high-dose serum containing Scabiosa atropurea groups had significant reductions in the protein expression levels of α-SMA, collagen Ⅰ, PI3K, Akt, and p-Akt and a significant increase in the protein expression level of PTEN (all P < 0.05). Conclusion The Mongolian medicine Scabiosa atropurea can inhibit the proliferation of HSC-T6 cells and promote their apoptosis, possibly by regulating fibrosis markers and the PI3K/Akt signaling pathway to exert an anti-liver fibrosis effect.
