Objective To study the action of puerarin on Caspase-3 and Bcl-2 expression of hippocampal CA1 neurons in ovariectomized rats, and explore its mechanism. Methods SD female rats were randomly assigned into sham operation group, model group, premarin group and puerarin groups (120, 60, 30 mg/kg). The model group and sham operation group were injected NS intraperitoneally, other groups were treated with corresping drugs for 30 d. Immunohistochemistry and RT-PCR were used to determine Caspase-3 and Bcl-2 expression of hippocampal CA1 neurons. Results Caspase-3 expression of hippocampal CA1 neurons was significantly decreased in high-dose puerarin group (P <0.05). Bcl-2 expression of hippocampal CA1 neurons was significantly increased in high- and medium-dose puerarin groups (P<0.05, P<0.01). Bcl-2 mRNA level of hippocampal CA1 neurons in high-dose puerarin group was significantly increased (P<0.05). Conclusion Puerarin can decrease Caspase-3expression and increase Bcl-2 expression of hippocampal CA1 neurons in ovariectomized rats, and has protective effect on neuronal structure.

Objective To explore the expression of cyclooxygenase-1 (COX-1) in cervical carcinoma and its significance. Methods The pathological specimens were collected from 62 female patients, who were admitted to 307 Hospital of PLA from Jan. 1999 to Mar. 2005, including 31 cases of cervical carcinomas, 15 cases of cervical intraepithelial neoplasia and 16 cases of normal cervix. Surgery or biopsy was performed. Expression of COX-1 was detected by immunohistochemistry, and the relationship between COX-1 and clinicopathological feature was analyzed. Results The major sites of COX-1 expression were localized in cytoplasm, and next in cell membrane. Strongly positive expression of COX-1 was observed in cervical carcinomas, and weakly positive expression of COX-1 in cervical intra-epithelial neoplasia, with positive rates of 81% and 13%, respectively. There was no COX-1 expression in normal cervix. A significant difference was observed among these specimens. No obvious correlation was found between COX-1 expression and patient's age, tumor differentiation degree snd clinical stages. Conclusion Expression of COX-1 may serve as an auxiliary parameter for diagnosis, therapeutic scheme option, and prognosis of patients with cervical carcinoma.

The biomarkers associated with coronary artery lesions (CAL) secondary to Kawasaki disease (KD) in Chinese children were investigated by using Meta-analysis. We searched documents published from January 1997 to December 2009 from medical electronic databases. According to inclusion and exclusion criteria, eligible full-text papers were identified. We conducted a comprehensive quantitative analysis by using Stata10.0 statistical software package to assess the heterogeneity among the documents, calculated the summary effect and analyze publication bias and sensitivity. A total of 92 documents and 16 biomarkers were identified. All documents were case-control studies, and included 2398 patients in CAL group and 5932 patients in non-CAL (NCAL) group. The Meta-analysis showed that the levels of platelet count, platelet hematocrit (PCT), neutrophils count, platelet distribution width (PDW), mean platelet volume (MPV), erythrocyte sedimentation rate (ESR), cardiac troponin I (cTnI), and endothelin-1 (ET-1) in CAL group were significantly higher than those in NCAL group, and serum albumin (Alb) and hemoglobin (Hb) levels were significantly lower in CAL group (all P<0.05). White blood cell (WBC) count, serum sodium, matrix metalloproteinase 9 (MMP-9), total cholesterol (TC), hematocrit (HCT) and CD3+T lymphocytes percentage had no statistically significant difference between the two groups. In conclusion, our results indicated that the 10 biomarkers including platelet count, neutrophils count, PCT, PDW, MPV, ESR, cTnI, ET-1, Alb and Hb were associated with CAL, and may be involved in the pathogenesis of CAL. The biomarkers of WBC count, serum sodium, MMP-9, TC, HCT, and CD3+T lymphocytes percentage bore no relationship with the development of CAL among Chinese children with KD.

This study evaluated the effects of early treatment with β-adrenergic blocker metoprolol on ventricular remodeling and function after acute myocardial infarction (AMI) by using high frequency ultrasound. The relationship between the efficacy and the expression level of cardiac myocardial inflammatory cytokine was examined in rats. The rat model of AMI was induced by ligating the left anterior descending artery. The surviving rats were randomly assigned to two experimental groups: MI control (MI) group and MI metoprolol (MI-B) group, with the rats undergoing sham operation serving as normal control (Sham). MI-B group was given metoprolol for 4 weeks (refer to the CCS-2 protocol) and the other two groups received equal volume of saline via intragastric (i.g.) administration. The ventricular remodeling and function were evaluated by high frequency ultrasound 4 weeks after the treatment. Then all rats were sacrificed for pathological examination and immunohistochemistrical detection of inflammatory cytokines, including IL-1β, IL-6, IL-10 and TNF-α. Compared with the MI group, the left ventricular end-systolic dimension, end-diastolic dimension, end-systolic volume and end-diastolic volume of the MI-B group were significantly decreased (P<0.01), while the left ventricular anterior wall end-diastolic thickness, ejection fraction and fractional shortening were obviously increased (P<0.01). The conspicuous improvement in the left ventricular morphology and function was coincident with the markedly reduced TNF-α and IL-1β expression and the increased IL-10 expression. We are led to conclude that early metoprolol treatment for AMI can regulate myocardial inflammatory cytokine expression to improve cardiac function and the underlying mechanism might be that it decreases the level of pro-inflammatory cytokines and increases the level of its anti-inflammatory counterparts in cardiac myocytes. Our study also showed that echocardiography is a useful technique for the structural and functional assessment of left ventricle after acute myocardial infarction.

Objective To study the effects of enteral nutrition( EN) on inflammatory factors and cardiac function in elderly patients with heart failure ( HF ) . Methods A total of 96 elderly patients with HF were enrolled in this study and randomly divided into treatment group A,treatment group B and control group( n= 32 in each group) . Patients in group A were provided with 500 mL of EN daily for 1 month, and those in group B were provided with the same dose of EN for 3 months. Control group was treated with normal diet. The nutrition status of each group was assessed by NRS2002. Meanwhile,all patients were evaluated by New York Heart Association(NYHA) class and left ventricle eject fraction(LVEF). The levels of BNP,IL-6, CRP and TNF-α were also measured before and after nutrition treatment. Results In group A and group B,BMI,TSF,AMC, TP,ALB and HGB increased. Symptoms of HF alleviated quickly and LVEF increased compared to the baseline. The levels of BNP,IL-6,CRP and TNF-α were significantly lower after treatment(P<0. 05) in both treatment groups,and the change in group B was more obvious(P<0. 01) than group A. However,in control group,there is neither evident improvement in cardiac function or nutrition status,nor in inflammatory factor levels. Conclusion Adding EN support to the normal treatment of heart failure in elderly malnourished patients with HF not only improves the function of heart and nutrition status, but also helps to support immune system so as to alleviate acute inflammatory response. The benefits from EN depend on the duration of therapy.

Objective To observe the expressions of Akt and ERK phosphorylation in abdominal aortic aneurysm of rat model, and explore the pathogenesis of abdominal aortic aneurysm. Methods The rat model of abdominal aortic aneu-rysm was established. The diameter of abdominal aorta was measured and the extended rate of the aorta was calculated. HE staining was used to observe the change of pathology. Immunohistochemistry and Western blot methods were used to detect the expressions of Akt and ERK phosphorylation in the level of protein. Results The dilation of aorta was significantly high-er in abdominal aortic aneurysm group than that of saline group and normal group (P＜0.05). HE staining showed structural disorder and inflammatory cell infiltration in abdominal aortic aneurysm group. The results of immunohistochemistry and Western blot results showed that phosphorylation of Akt expression was significantly higher in abdominal aortic aneurysm group than that of saline group and normal group (P＜0.05). There was no significant difference in phosphorylation of ERK expression between three groups (P>0.05). Conclusion PI3K/Akt signaling pathway may be involved in the development of abdominal aortic aneurysm.
