OBJECTIVETo observe the effect of Oxymatrine on left cardiac function and ventricular remodeling in rabbits after acute myocardial infarction.

METHODSLigation of the left anterior descending artery was adopted to establish acute myocardial infarction model, forty eight rabbits were randomized into the sham operation group, model group and Oxymatrine group. Eight models were successfully established in each group. the sham operation group and model group were given conventional feed. Oxymatrine were gavage administration 0.5 ml/100 g, once a day, lasted for 4 weeks. Respectively in postoperative week, and three weeks, to observe the Oxymatrine on cardiac output (CO), left ventricular end systolic pressure (LVESP), left ventricular end-diastolic pressure (LVEDP), left indoor pressure change rate peak (dp/dtmax)), and left ventricular cavity internal diameter (D), ventricular weight index (VWI), ventricular weight (VW).

RESULTSLeft ventricular anterior wall was from red to deep purple, electrocardiogram showed II guide ST-segment camber up ≥ 0.25 mv. Postoperative week in Oxymatrine group compared with model group, LVESP increased significantly (P < 0.01), LVEDP decreased obviously (P < 0.01); After three weeks in Oxymatrine group compared with model group, VW, VWI decreased (P < 0.05), D significantly reduced (P < 0.01); LVESP increased significantly (P < 0.01), LVEDP decreased obviously (P <0.01); dp/dt(max), CO increased (P < 0.05).

CONCLUSIONAfter acute myocardial infarction in rabbit Oxymatrine can improve the left ventricular reconstruction parameters, increase cardiac output, and improve cardiac function.

Method: Two hundreds cases of chronic prostatitis were randomly divided into the treatment group and control group, 100 cases in each group, to observe the therapeutic effects in the clinical symptoms before and after acupuncture treatments and compare the therapeutic effects of the acupoints between the two groups. Results: Clinical subjective symptoms and examination of prostatic fluid were obviously improved in the treatment group (Group Ⅰ) than in the control group (Group Ⅱ), and the effective rate was 100% in the treatment group and was 91% in the control group, in a significant difference (P ＜ 0.01).Conclusion: There is a remarkable therapeutic effect in the treatment of chronic prostatitis by puncturing four acupoints at the root of penis in combination with related acupoints.

Objective To investigate the levels of matrix metalloproteinase-9 (MMP-9) expression in different grades of glioma and the relationship with MRI characteristics. Methods Thirty-one patients of glioma confirmed pathologically were divided into two groups: low grade group (grade Ⅰ and Ⅱ, n=20) and high grade group (grade Ⅲ and Ⅳ, n=11). MMP-9 expression levels were evaluated with immunohistochemical staining. Plain and enhanced MR scan were performed in all patients before operation. Peritumoral edema index (EI), enhance percentage (EP) and the tumor's maximum diameter were recorded as characteristics of MRI. Results The expression levels of MMP-9, EI, EP and the tumor's maximum diameter were significantly higher in the high grade group than those in the low grade group (t=6.312, 4.405, 6.286 and 5.026, respectively, all P＜0.05). The expression of MMP-9 were found significantly correlated to EI, EP and the maximum diameter of tumor (r=0.516, 0.554 and 0.676, respectively, all P＜0.05). The expression levels of MMP-9 were significantly different between tumors with heterogeneity and even signal (t=2.637, P＜0.05), but not between tumors with unclear border and clear border definition (t=0.906, P＞0.05). Conclusion MMP-9 expression have close relationship with invasion of glioma. EI, EP, the maximum diameter and signal of tumor can reflect the level of MMP-9 expression, and may be used to estimate tumor's malignant behavior, being able to provide the evidence for future clinical operation.

Objective To investigate the correlation of serum advanced glycation end products (AGEs) and the expression of receptor for AGE (RAGE) with mental disorders in senile people. Methods All the subjects aged 65～67 years were divided into 4 groups: healthy control (31 cases), Alzheimer's disease (AD) (36 eases), vascular dementia (VD) (20 cases) and mental disorder (MD) (28 cases). Fluorospectrophotometry was carried out to measure the AGEs levels in serum samples, and reverse transcription polymerase chain reaction (RT-PCR) was used to determine the mRNA levels of RAGE in white blood cells. Results AGEs levels were 477. 1±36.2, 512. 6±33.2 and 415.2±32.5 AU/ml in AD, VD and MD group, respectively, which were higher than that in healthy control group (357.4±28. 2) AU/ml (F=3.77,P<0. 05). The mRNA levels of RAGE(RAGE/b- actin) were found to be 1.12±0.34, 1.27±0.41 and 1.18±0.42 in AD, VD and MD group, respectively, which were also significantly higher than that in healthy control group(0. 92±0. 37, F= 4. 07,P<0. 01). However, no significant differences were found in RAGE mRNA levels among the three groups of AD,VD and MD (F=0. 979,P>0. 05). The mRNA levels of RAGE in WBCs were found to be positively correlated with the serum AGEs levels (r=0. 442, P<0. 01). Conclusions Compared with patients in healthy control group, the serum AGEs levels and RAGE mRNA levels are significantly increased in patients with AD, VD and MD. The interaction between AGEs and RAGE may be involved in the pathogenesis of mental disorders in senile people.
