Objective To explore the MRI finding of female normal levator ani muscle and the levator ani muscle injuries and to evaluate the correlation between childbirth and levator ani muscle injuries. Methods One hundred asymptomatic nulliparous women(control group)and 200 vaginally primiparous women(study group)were selected as the object of this study.Moreover,the study group was divided into two subgroups:group A(100 cases)with stress incontinence,group B(100 cases)without clinical symptoms.Multiplanar proton density magnetic resonance images were obtained at 0.5 cm intervals from these study individuals.All images were used to analyze the differentiation of MRI features between normal levator ani muscle and levator ani muscle injuries.Results No levator ani injuries were identified in the control group.Fifty-four primiparous women(27%)had visible injuries in their levator ani muscles,42 in group A and 12 in group B.Injuries were identified in the puborectalis muscle in 49 cases and in the iliococeygeus muscle in 5 cases(X~2=41.447,P

OBJECTIVETo observe the effect and safety of plastering Chinese Compound Shenhuang Ointment (CSO) at Shenque (RN8) in promoting the rehabilitation of postoperative gastrointestinal dysfunction patients of qi stagnation blood stasis syndrome (QSBSS).

METHODSA prospective, multi-centered, randomized, double-blinded, controlled trial was conducted in 220 postoperative gastrointestinal dysfunction patients of QSBSS. They were randomly assigned to two groups, the CSO group (110 cases) and the placebo group (110 cases). CSO was plastered at Shenque (RN8) for 5 days after operation. The time of exhaustion, defecation, the recovery of intestinal peristalsis, integrals of TCM syndrome, and serum levels of motilin (MOT)and somatostatin (SS) were observed.

RESULTSCompared with the placebo group, the condition of exhaustion and defecation, the recovery of intestinal peristalsis on the 3rd day after operation was all improved (P < 0.05). The integrals of TCM syndrome at day 2, 3, and 4 were more significantly lowered in the CSO group than in the placebo group (P < 0.01, P < 0.05). The total effective rate of TCM syndrome was 95.3% in the CSO group, better than that in the placebo group (91.8%, P < 0.05). Compared with the placebo group, the serum MOT level increased and the serum SS level decreased at day 5 after operation in the CSO group (P < 0.05).

CONCLUSIONSThe plastering of CSO at Shenque (RN8) could advance the time of exhaustion and defecation, and improve patients' clinical symptoms. And patients could tolerate well.

OBJECTIVETo investigate the role of Maspin protein in the development of oral squamous cell carcinoma (OSCC), with the effort to realize practical diagnosis use of them.

METHODSThe expression status of Maspin protein in 45 cases of OSCC, 33 cases of paratumor tissue and 15 cases of normal tissue was examined by immunohistochemical staining.

RESULTSThe positive rates of Maspin protein were 86.67% (13/15), 72.73% (24/33) and 37.78% (17/45) in normal tissue, paratumor tissue and OSCC. The expression of Maspin protein increased respectively in OSCC, paratumor tissue and normal tissue. The expression were different between OSCC and normal tissue, OSCC and paratumor tissue, paratumor tissue and normal tissue (P<0.05). The expression of Maspin protein was correlated with lymph node metastasis, histological grade (P<0.05), but not with TNM staging (P>0.05).

CONCLUSIONMaspin protein may play an important role in the development of OSCC. The expression level of Maspin protein detected in early time might be a useful prognostic marker for the diagnosis of lymph node metastasis.

OBJECTIVETo investigate the effects of pravastatin, fosinopril and their combination on ventricular remodeling, cardiac function, tumor necrosis factor-alpha (TNF-alpha) mRNA expression, and matrix metalloproteinases (MMPs) activities after myocardial infarction (MI) in rats.

METHODSAcute myocardial infarction (AMI) was established by ligation of the anterior descending coronary artery in male Sprague-Dawly (SD) rats. Twenty-four hours after the procedure, the 48 surviving rats were grouped randomly as AMI control, fosinopril (10 mg.kg(-1).d(-1)), pravastatin (20 mg.kg(-1).d(-1)) and a combined use of the 2 drugs. Sham-operated group (n = 8) was taken randomly as non-infarction control. Six weeks after treatment with the drugs by gastric gavage, heart function and left ventricular remodeling were assessed. Left ventricular weight (LVW)/body weight (BW) ratio was determined. The relative expression of myocardium TNF-alpha mRNA was assessed by reverse transcription-polymerase chain reaction. Left ventricular myocardium MMPs activities were assessed by Zymography.

RESULTSThere were no significant differences among the four AMI groups in infarction size (P > 0.05). In comparison with the AMI group, left ventricular end-diastolic pressure, left ventricular end-diastolic diameter, LVW/BW all decreased significantly (P < 0.05 - 0.01); while dp/dtmax, dp/dtmin, fractional shortening (FS) and ejection fraction (EF) increased significantly in all three drug-treated groups (P < 0.05 - 0.01); increments of FS, LVEF and dp/dtmax were more evident in the combination group than either the fosinopril or pravastatin group (P < 0.05). The levels of TNF-alpha mRNA in AMI rats treated with fosinopril, pravastatin and their combination reduced 29%, 26% and 33%, respectively (P < 0.01); MMP-2 activity reduced 25%, 30% and 35%, respectively (P < 0.01); MMP-9 activity reduced 20%, 18% and 24%, respectively (P < 0.01). There were no significant differences in other variables among the 3 treatment groups (P > 0.05).

CONCLUSIONPravastatin, fosinopril and their combination showed favorable effects on left ventricular remodeling after AMI in rats and demonstrated improved cardiac function. The combined treatment group yielded better results in the context of improving left ventricular systolic function. These effects could be relevant to the attenuation of increased MMP-2 and MMP-9 activities and left ventricular expression of TNF-alpha.
