Objective To evaluate the effect of low-dose omeprazole in the treatment of functional dyspepsia(FD).Methods A total of 260 FD patients were diagnosed clearly and divided into two groups randomly:148 cases(observation group)were treated with low-dose omeprazole(10 mg/d),while 112 cases(control group)were treated with esomeprazole(20 mg/d)and domperidone(each 10 mg,three times per day).Two groups were all treated for 2 weeks.The clinical symptoms such as heartburn,postprandial distenstion,epigastric pain and eructation were observed.Results Compared with symptoms in two groups before treatment,the scores of heartburn and epigastric pain were decreased evidently after treatment in two groups(P

Objective To investigate the effects of sterigmatocystin(ST) on the ependymal cells,neurons and endothelial cells of blood vessel of the lateral recess of the fourth ventricle in BALB/c mice in vivo after single oral administration. Methods BALB/c mice were treated intragastrically by gavage with ST 3000??m/kg.The mice were killed 1 hour,2 hours,4 hours,8 hours,16 hours after oral administration respectively for observing ependymal cells,neurons and endothelial cells of blood vessel of the lateral recess with transmission electron microscopy(TEM).Results After oral administration of ST pinocytosis vesicles began to increase in endothelial cells of blood vessel in 1 hour,apocrine of ependymal cells began to increase and myelin sheath degeneration appeared in 2 hours,extensive myelin sheath degeneration and mitochondrion degeneration and incisure and vacuoles in nucleus of neuron were found in 4 and 8 hours.Lipofuscin was found in cytoplasm of neuron 16 hour.Conclusion Oral ST exposure in mice could cause myelin sheath degeneration and damaged changes of neurons.

0.05). Conclusions:Compared with normal esophageal mucosa, the expression of HSP27 mRNA in esophageal squamous carcinoma and mucosa with atypical hyperplasia was markedly decreased.This indicated that the expression of HSP27 mRNA to a greater or less extent lost in the carcinogenesis and development of esophageal squamous carcinoma. To up-regulate the expression of HSP27 mRNA in esophageal squamous carcinoma may be a very effective biological therapy.

Objective To explore different intervention methods on the risk factors of cardiovascular disease for women with severe pre-eclampsia history.Methods 78 patients with a history of severe preeclampsia in the hospital from November 2006 to November 2008 were chosen as the research subject.They were divided into the observation group and the control group according to the adopted different methods of intervention with 39 patients in each group.The control group was taken with conventional interventions for obesity intervention,and the observation group was treated with standard behavior therapy (SBT).The improving situations of the related risk factors for cardiovascular disease after three months for the two groups were compared.The effect of different intervention methods on the risk factors of cardiovascular disease was evaluated for women with severe pre-eclampsia history.Results After the intervention,the cardiovascular risk factors (systolic blood pressure,body mass,waist circumference,fasting glucose,total cholesterol/high density lipoprotein) of the two groups improved significantly than before the intervention.But the improvement effect of the observation group was better than the control group,the differences between the two groups were significant.Conclusions The intervention effect on risk factors of cardiovascular disease by standard behavior therapy for women with severe pre-eclampsia history is better than conventional way,which is worthy of clinical application.

The education,as well as the fostering environment,of the basic medical college postgraduates has its strong "local features".Our college exerts the subject advantages,empha-sizes on the feature-fostering mode,and implements level-management(That is: college—teaching office—scientific research office).Management is centered on the daily fostering of the depart-ment,teaching office and scientific research office.With the target management as the guidance,we strengthen process management of different stages including the study of basic knowledge,topic-selection,topic opening,experiment research and thesis-writing while attaching importance to the behavioral management,consciousness of teamwork,spirit of commitment and devotion,foster and improve the comprehensive quality of communication ability,pursuit of truth etc.

Objective To develop a portable jet-flow device for preliminary debridement of wound mainly in battlefield,which can also be used for the treatment of nuclear or chemical weapon injury at wartime and peacetime.Methods The device was composed of a dynamic system,a servo system and consumable accessories,and developed based on a pneumaticpower scheme.Composite power unit free of dependence on electric power transferred the pneumatic power to three kinds of disinfectants through the four-way pipes.Results The device with easy operation consumed a few disinfectant and completed debridement within 30 minutes,with infection avoided effectively.Conclusion The device gains advantages in low weight,compact structure,function and low cost,and can be used for early debridement in field conditions.

AIM: To investigate the influence of GM-CSF on human vascular endothelial cells induced to form new blood vessels and the role of VEGF.METHODS: HUVECs were cultured by Matrigel to set up a stable angiogenesis system with the stimulating factors.The rhGM-CSF concentration-dependent and time-dependent effects and the role of VEGF165 were detected.CD34 was measured by immunochemical staining and numbers of vessel formation was calculated under microscopic observation.RESULTS: After treatment with rhGM-CSF at various concentrations and at different time points,the numbers of vessel formation increased in a dose-dependent and time-dependent manner.In the presence of VEGF165,the numbers of vessel formation increased evidently.CONCLUSION: HUVECs were induced to develop tubular structure in vitro cultured with Matrigel.GM-CSF promotes human vascular endothelial cells to form vessel-like structure in vitro in a dose-dependent and time-dependent manner.VEGF also in vitro promotes human vascular endothelial cells to form new vessel-like structure.

Aim To study the effects of amitriptyline(Ami)on focal cerebral ischemia-reperfusion injury in rats.Methods An animal model of focal cerebral ischemia-reperfusion injury was induced by the middle cerebral artery occlusion(MCAO) by reversibly inserting a nylon thread method.The rats were decapitated after ischemia for 1 hour and reperfusion for 2 hours.The infarct volumes were determined using a 2,3,5-tri-phenyl tetrazolium chloride(TTC) staining and assessed by image analysis system.The neurologic deficit status were evaluated on 0~5 grade scale.The levels of dopamine(DA),norepinephrine(NE),serotonin(5-HT) and its metabolic product~hydroxyindole acetic acid(5-HIAA) in cortex and striatum were measured by fluoro-spectrophotometry.Results Ami treatment exhibited a remarkable reduction in infarct volume and neurologic deficit scores.The monoamines content of cortex and striatum had a significant increase compared with ischemia-reperfusion group.Conclusion Amitriptyline has protective effect on cerebral ischemia-reperfusion injury in rats.The mechanism might be related to reducing the release of NE,DA and 5-HT during cerebral ischemia-reperfusion,attenuating or inhibiting of the neurotoxic effects of monoamine neurotransmitters.

Objective The effectiveness on the enrichment of nuclear red blood cells(NRBC) in umbilical cord blood by polyvinylidene difluoride membrane was investigated with intervention on membrane ionic channels.Methods NRBC was isolated by the isolation solution with a density of 1.067 g/ml.The rates of the cell enrichment using verapamil and furosemide intervention by discontinuous density centrifugation were examined by flow cytometry.The NRBC that past through PVDF membrane with pore size of 5 ?m were checked and quantified by nested-PCR.Results The optimal centrifugation density was 1.067 g/ml.The mean purity of NRBC after centrifugation was 2.54%,yet the purity after intervention increased to 9.36%(3.7-fold increment).The NRBC passing through PVDF membrane was from 0.83% to 6.15%,with enrichment of 7.4 times.When NRBC was 120 cells/ml,the density of the nested PCR products increased by nearly 4 times after intervention(4.48 vs 17.78).Conclusions Verapamil and furosemide could affect the morphology of cells and promote the rate of NRBC enrichment.
