Objective: To explore the mechanisms of emodin in protecting intestinal mucosal barrier in rat with severe acute pancreatitis (SAP). Methods: Sixty SD rats were randomly divided into three groups: sham-operation group, untreated group, and emodin group. SAP in rats of the untreated group and the emodin group was induced by retrograde pumping of 3.0% sodium cholate to the common bile duct. Specimens were obtained 24 hours after the severe acute pancreatitis was induced. Serum level of leptin, serum activity of amylase and plasma content of endotoxin were measured. Ileum mucosa from ileocecal junction was observed by light microscopy and electron microscopy to measure pathological and ultrastructural changes. Apoptosis of ileum mucosal cells was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method, and expression of Bax in ileum mucosal cells was measured by immunohistochemical method. Results: Compared with the sham-operation group, there was significant increase in the levels of leptin, endotoxin, the activity of amylase, apoptosis index and Bax expression in the untreated group (P<0.01). Compared with the untreated group, the level of endotoxin, apoptotic index and Bax expression level in the emodin group were significantly reduced (P<0.01) and the leptin level was increased (P<0.05). More severe pathological changes appeared in the untreated group than in the sham-operation group under the light and electron microscopes; meanwhile less severe damage was observed in the emodin group as compared with the untreated group. Conclusion: Emodin can inhibit the apoptosis of intestinal mucosa cells and up-regulate the serum leptin content to protect the intestina1 barrier function and prevent the translocation of bacteria and endotoxin.

OBJECTIVE:To investigate therapeutic efficacy and safety of levamlodipine and telmisartan combined with hydro-chlorothiazide in the treatment of anti-dipper hypertension. METHODS:Totally 150 patients with anti-dipper hypertension were ran-domly divided into group A,B,C,with 50 cases in each group. Group A was given Telmisartan tablet 40 mg+Hydrochlorothiazide tablet 10 mg,once a day,in the morning. Group B was given Levamlodipine tablet 5 mg,once a day,in the night. Group C was given Telmisartan tablet(usage and dosage same as group A)+Hydrochlorothiazide tablet(usage and dosage same as group A)+Le-vamlodipine tablet(usage and dosage same as group B). Treatment courses of 3 groups lasted for 8 weeks. The changes of electro-lyte and 24 h ambulatory blood pressure were observed and compared among 3 groups before and after treatment. The incidence of adverse reactions was recorded. RESULTS:There was no statistical significance in the electrolyte indexes in 3 groups before and af-ter treatment(P>0.05). Before treatment,there was no statistical significance in 24 h blood pressure among 3 groups(P>0.05). Af-ter treatment,the 24 h blood pressure of the patients in the 3 groups after treatment was lower than before treatment,and group C was lower than that of the group A and group B(P<0.05). After treatment,the rate of anti-dipper rhythm reversal in group C was significantly higher than group A and B,with statistical significance(P<0.05). There was no statistical significance in the inci-dence of ADR among 3 groups(P>0.05). CONCLUSIONS:Levamlodipine and telmisartan combined with hydrochlorothiazide show good therapeutic efficacy for anti-dipper hypertension,and can reduce 24 h blood pressure and effectively reverse anti-dipper rhythm with good safety.

ObjectiveTo explore the ultrasound characteristics of coronary artery fistula to improve its prenatal diagnosis.MethodsImaging data for 12 fetuses with coronary artery fistula who underwent fetal echocardiography at our hospital from June 2005 to December 2013 were retrospectively analyzed to summarize the ultrasound characteristics of coronary artery fistula.ResultsOf the 12 fetuses, 7 were confirmed with coronary artery fistula by echocardiography after birth, and the remaining 5 were aborted due to other cardiac abnormalities (since an autopsy was not performed, the diagnosis of coronary artery fistula could not be confirmed). Of the 7 confirmed cases, 1 had left coronary artery-to-right atrium fistula, 3 had left coronary artery-to-right ventricle fistula, and 3 had right coronary artery-to-right ventricle fistula; 1 had left coronary artery-to-right ventricle fistula with muscular ventricular septal defect, and 6 had simple coronary fistula. Two-dimensional ultrasound examination revealed that coronary arteries were displayed in all cases, and the diameter ranged from 1.8 to 4.0 mm. Color Doppler ultrasound clearly showed the fistula size, course and the situation fistulas drained into heart chambers. Diastolic regurgitation signal could be detected in the ascending aorta and aortic arch.ConclusionCoronary artery fistula can be diagnosed by color Doppler ultrasound combined with spectral Doppler ultrasound when the fetal coronary artery expands.

Objective To investigate the changes in the concentration of myocardin in children with lupus nephritis (LN) under different degree of vessel damage.Methods Forty-nine children diagnosed with LN by routine tissue immunolfuorescence, light microscope, and electron microscope were included, and 30 healthy children were included as control group. The pathological classiifcations were performed according to the ISN/RPS 2003 LN pathological classiifcation criterion. According to the Katafuchi evaluation method, the semi quantitative assessment of glomerular and kidney tubule damage was carried out, and the degree of vascular damage was evaluated at the same time. Double antibody sandwich method was used to detect the concentration of serum myocardin.Results The glomerular and kidney tubules damage in children with LN were signiifcantly aggravated with higher pathological classification (P<0.05). Glomerular damage was positively correlated with renal interstitial damage (r=0.96, P<0.01). The degree of vascular damage was related to the degree of glomerular injury and renal interstitial injury, while it was no related with the results of clinical tests. There were different concentrations of myocardin among mild-, moderate-, severe-vessel damage and control groups (F=378.61,P<0.001), and the concentration of myocardin in moderate- and severe-vessel damage groups were obviously lower than those in control group and mild-vessel damage group (P<0.01) while there was no difference between control group and mild-vessel damage group (P>0.05). According to pathological type, there were signiifcant differences in the concentration of myocardial between control group and different pathological types (F=626.793,P<0.01). FromⅡ,Ⅲ,Ⅲ+Ⅴ,Ⅳ toⅣ+Ⅴ, the concentrations of myocardial were decreased systematically, and there were statistic differences between groups (P all<0.05).Conclusion The concentration of myocardin in children with LN can relfect the renal vascular damage to a certain extent. Elevation of myocardin concentration may be helpful for the repair of vascular damage.
