Objective To investigate the curative effect of Teprenone combined with esomeprazole for reflux esophagitis. Methods 96 cases of reflux esophagitis comfirmed by endoscope were obtained and divied into observation group and control group randomly. Both groups were offered with esomeprazole and motilium. Teprenone was added to the observation group and sucralfate was added to the control group. Clinical effective rate,healing rate,adverse reactions and one-year follow up were observed closely after the course of 8 weeks. Results The relief time of clinical symptom and total effective rate in the observation group were(9.3 ±3.5)d and 95.8% respectively,which were significantly higher than those in the control group(P <0.05). Endoscopic effective rate was 93.8% in observation group and 81.2% in control group respectively and statistically significant difference was observed (P <0. 05). Recurrence rate after one year in the observation group was 8. 3% ,which was significantly lower than in the control group (P < 0.05). One case of headache and nausea occurred in both groups but no severe adverse reaction was observed. Conclusion Teprenone combined with esomeprazole were more effective and more likely to approach the complete cure for reflux esophagitis.

In present study, animal model of cardiac hypertrophy induced by abdominal aortic stenosis was utilized, and the lysosomes were investigated by electron microscopy and ultrastructural cytochemistry. The results showed that while cardiac hypertrophy developed, lysosomes participate in apparent remolding of cardiac muscle cells; in the late stage of cardiac hypertrophy, a great deal of autophagocytoses were viewed in some muscle cells which may result in irreversible cell damage.

Objective To evaluate the effects of impaired glucose tolerance (IGT) on ventricular remodeling. Methods Parameters of every subject including left ventricular mass ( LVM), left ventricular mass index (LVMI), E/A ratio, 75 g oral glucose tolerance test (OGTT), ambulatory blood pressure monitoring(ABPM) data including 24-hour mean systolic blood pressure(mSBP) and 24-hour mean diastolic blood pressure(mDBP) were collected. Then the relationship of IGT and myocardial remodeling related parameters were analyzed. Results The rate of diastolic dysfunction was higher in the IGT combined with hypertensive group(74% ) compared with the hypertensive group( 39% )( x2 = 6. 5, P < 0. 05 ). The rate of diastolic dysfunction was higher in the IGT group( 34% ) compared with the normal group( 10% ) (x2 = 5.2,P <0. 05). The rate of Left Ventricular Hypertrophy (LVH)in the IGT combined with hypertensive group (24%) was higher than the other three groups (Hypertension group 7%, IGT group 0, Normal group 0) (x2 =4.561,P <0.05), and there was no significance between the rest three groups (P >0.05).Stepwise multiple regression showed age and 2 Hours' Postprandial Blood Glucose were independent risk factors of E/A ratio. Conclusions These results suggested that IGT is a possible contributor to left ventricular hypertrophy and diastolic dysfunction, and is one of the histopathology of left ventricular remodeling.

Objective To study the effect of chloride channel blocker(niflumic acid,NFA) on pulmonary hypertension induced by high pulmonary blood flow in rats.Methods Fifty male or female Sprague-Dawley rats were randomly divided into 5 groups:normal group,sham group,model group,drug 1 group,and drug 2 group,with 10 rats in each group.After subjected to an abdominal aorta-inferior vena cava shunt,all the rats were reared under the same condition for 11 weeks.Then,mean pulmonary artery pressure(mPAP) and right ventricular hypertrophy index(RVHI) of each rat were measured.In addition,arterial wall area/vessel area (W/V) and arterial wall thickness/vessel external diameter(T/D) of each rat were also measured.Results 1.The mPAP of model group [(25.79 ± 4.03) mmHg,1 mmHg =0.133 kPa] was significantly higher than those of normal group [(16.48 ± 1.70) mmHg],sham group [(17.03 ± 2.01) mmHg],drug 1 group [(21.78 ± 2.77) mmHg] and drug 2 group [(20.31 ± 2.15) mmHg] (F =18.983,P <0.01).Although the mPAP of drug 1 group was a little higher than drug 2 group,there was no significant difference (P > 0.05).Compared with normal group and sham group,the mPAP of drug 1 group and drug 2 group increased(P <0.01,respectively).2.The W/V and T/D of model group were significantly higher than those of normal group,sham group,drug 1 group and drug 2 group (F =26.135,15.527,all P < 0.001).The W/V and T/D of two drug groups showed no significant difference,but they were higher than those of normal group and sham group (P < 0.01,respectively).Conclusions Chloride channel blocker NFA partly decrease mPAP of pulmonary hypertension indnced by high pulmonary blood flow in rats,and inhibit proliferation of vascular smooth muscle cells.These results suggest that NFA had part of therapeutic effect to pulmonary hypertension induced by high pulmonary blood flow.

OBJECTIVE:To establish the HPLC fingerprints for Sini decoction and compare the differences of compositions of Sini decoction prepared by traditional decoction and modern machine decoction. METHODS:HPLC was performed on the column of Kromasil C18 with mobile phase of acetonitrile-0.1% phosphoric acid(gradient elution)at a flow rate of 1.0 ml/min,the detec-tion wavelength was 235 nm,column temperature was 30 ℃,and injection volume was 10 μl. The HPLC fingerprints of 10 batch-es of Sini decoction were determined with reference peak of liquiritin peaks,and common peak identification and similarity evalua-tion were conducted by using Chromatographic Fingerprint Similarity Evaluation System(2004 A edition). RESULTS:There were 18 common peaks and the similarity was no less than 0.982. According to the verification,the fingerprint of 10 batches of Sini de-coction showed good similarity with reference fingerprint,and the similarity of 10 batches of Sini decoction was high,which was prepared by the 2 methods. CONCLUSIONS:The established fingerprint is specific and stable,and can provide reference for quali-ty evaluation and control for Sini decoction;and there are no obvious differences in the main chemical compositions of Sini decoc-tion prepared by traditional decoction and modern machine decoction.

AIM: To investigate the effects of calcitonin gene-related peptide (CGRP) on cultured anoxic-reoxygenation human umbilical vein endothelial cells. METHODS:In the present experiment, an anoxic-reoxygenation model was established by using cultured human umbilical vein endothelial cells. The uptake rate of trypan-blue and calcium and magnesium contents of endothelial cells and lactic dehydrogenase (LDH) activity in medium and malondialdhyde (MDA) content of endothelial cells were measured 60,120 and 180 min after anoxia and 30 and 60 min after reoxygenation, and the effects of 1?10 -8 mol/L CGRP on anoxic-reoxygenation endothelial cells were studied. RESULTS: The findings showed that, as anoxia prolonged, the uptake rate of trypan-blue and LDH activity and MDA content gradually elevated and, during reoxygenation, these parameters sharply increased. Calcium and magnesium levels gradually declined as anoxia prolonged, and during reoxygenation calcium content significantly increased. Meanwhile, 1?10 -8 mol/L CGRP might significantly reduce the uptake rate of trypan-blue and LDH activity and MDA content during anoxia and reoxygenation and lessen the increase in calcium content and the loss of magnesium during reoxygenation. CONCLUSION: These results showed that CGRP might have a direct protective function to endothelial cells afflicted with anoxic-reoxygenation injury by inhibiting lipid peroxidation, attenuating calcium overload and loss of magnesium and enzyme.
