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.

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.

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.

ObjectiveTo investigate the influence of Tanshinone Ⅱ A on the expression of HMGB1 in rats with cerebral ischemia-reperfusion (I/R) injury and its neural function protection.MethodsThe 32 male SD rats were randomly (random number) divided into 4 groups (8 rats per group):Sham group,I/R group,group with low dose of Tanshinone Ⅱ A ( TaLD group) and group with high dose of Tanshinone Ⅱ A (TaHD group).The cerebral I/R models were established by the method of right middle cerebral artery occlusion (MCAO).Cerebral infarct volume was detected by TTC staining.Apoptotic cell and apoptotic index were calculated by Tunnel assay.The HMGB1 levels in brain and serum was detected by Western blot and ELISA.Calmodulin (CaM) activity and malondialdehyde (malondiadehyde,MDA) content in the brain were also detected.ResultsCompared with the Sham group,the volume of cerebral infarction,the number of apoptotic cells,CaM activity,MDA content,HMGB1 levels in the brain tissue and serum in group I/R,TaLD group and TaHD group increased significantly (P ＜ 0.01 ).Compared with the group I/R,the volume of cerebral infarction,the number of apoptotic cells,CaM activity,MDA content and the HMGB1 levels in brain tissue and serum in TaLD groupand TaHDgroup decreased significantly (P ＜ 0.01 ).The difference of the above index between TaLD groupand TaHDgroup was significant ( P ＜ 0.01 ).ConclusionsTan Ⅱ A could reduce the cerebral ischemic reperfusion injury in rats which was likely related with decreasing the inflammatory response in the late stage via HMGB1.

Objective To summarize the cytological features of breast carcinoma by fine needle aspiration and differential diagonsis of breast hyperplasia and breast flbroadenoma. Methods Cytological features about 175 cases of breast cancer were analyzed,contrasted with 76 cases of breast hyperplasia and 93 eases of fibroadenoma. And 20 cases of low-diagnosis breast cancer were analyzed, compared with 13 cases of excessive diagnosis. Results The followings were found:disorderly arranged cells in 169 cases of breast cancer, about 96.9% in 175 cases,loose distance between the nucleus in 125 cases of all cases (about 71.4%). The percentage of small groups or scattered cells, medium size cells, round nucleus and irregular border nucleus was 34.3% (60/175) ,81.1% (142/175), 88.6% (155/175) and 28.6% (50/175) respectively. The nucleus/cytoplasm ratio was increased in 105 cases of all (about 60%). The nucleus/cytoplasm ratio was obviously reduced in 15 cases of all (about 8.6%). Big nucleolis were observed in 49 cases of all (about 28%). There was significant difference between nucleus size in 136 cases of all (about 77.7%). There was not myoepithelial cell in 168 cases of all (about 96%). The percentage of visible necrosis, scsttered round nucleus and integrity of cytoplasmic was 13.7% (24/175) ,89.7% (157/175), 66.9% (117/175) respectively. The cases of all above features were significantly more than those of breast hyperplasia and breast fibroadenoma (P <0.05). The percentage of large number of cells was 52.6% in 175 breast cancer cases,higher than 5.3% in 76 breast hyperplasia cases. There was a significant difference(P <0.05) between two groups. In 20 cases of low-diagnosis breast cancer the percentage of round nucleus with integrity of cytoplasmic, special arrangement cells was 70% (14 cases) ,35% (7 cases) ,higher than the cases in 13 excessive diagnosis cases. There was a significant difference(P < 0.05) between two groups. Conclusion The cell morphological characteristics of breast caner by fine needle aspiration are large number of cells, loose distance between the nucleus, disorderly arranged cells, small guoups or scattered cells, integrity of cytoplasmic, increased nuclear, round nuclear, irregular border nucleus,increased or decreased nucleus/cytoplasm ratio, big nucleoli, significant difference in nuclear size, no myoepithelial cell, visible necrosis. Most of breast cancer can be distinguished from breast hyperplasia and breast fibroadenoma by above characteristics. All those cytological characteristics are helpful to identify difficult case.

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.
