Objective To observe the changes of serum gastrin (GAS)and plasma motilin (MTL)in patients with primary bile reflux gastritis.Methods 80 patients with primary bile reflux gastritis were selected.The serum GAS and plasma level of MTL were observed,and the results were compared with 80 healthy people.Results The content of MTL in plasma of the study group (282.37 ±31.56)pg/mL was significantly lower than that in the control group (t =-21.352,P <0.01).The level of serum GAS (91.28 ±27.71)pg/mL was significantly higher than the control group (t =-28.388,P <0.01).Conclusion Compared with the healthy people,secretion of MTL in patients with primary bile reflux gastritis has insufficient phenomenon,and has the excessive secretion of GAS in the body,this may be a factor in the pathogenesis of the disease.

Objective: To investigate the effect of Trichostatin A (TSA) on histone acetylation and expression of ING1b mRNA in Colo205 human colon cancer cell line. Methods: Human colon cancer Colo205 cells were cultured and divided into 4 groups. Cells in the control group (group A) was treated without TSA. In the other three groups, cells were treated with 3 different concentrations of TSA: 50μg/L (group B), 100μg/L (group C), and 200μg/L (group D). At 24 hours after treatment, the level of histone H3 acetylation was analyzed by chromatin immunoprecipitation (CHIP) and the expression of ING1b mRNA was detected by RT-PCR with qPCR. The growth of Colo205 human colon cancer cells in group C and D was obviously inhibited compared with that in group A and B. Results: The Ct value of histone H3 acetylation and mRNA expression of ING1b in group A were 23.25± 0.08 and 23.32±0.05, respectively. After treatment with TSA, the 2~(-△△Ct) value of histone H3 acetylation in group B, C, and D were 1.12, 4.21 and 4.38, respectively. The level of histone H3 acetylation in group C and D was increased more compared with that in group A (P<0.05) and there was no difference between group B and group A (P>0.05). The 2~(-△△Ct) value of the expression of ING1b mRNA in group B, C and D were 1.33, 4.52 and 4.62, respectively. The expression of ING1b mRNA in group C and D were more than that in group A (P<0.05). Group B and group A had a similar level of ING1b mRNA expression (P>0.05). Conclusion: The histone acetylation is probably responsible for ING1b expression silencing in Colo205 human colon cell line. TSA at 100μg/L can increase the level of acetylation and activate the gene transcription which is silenced by low level of acetylation and induce the expression of gene, inhibiting the growth of tumor cells.

Objective To investigate the curative effects of B-ultrasound guided radio frequency therapy in the treatment climacteric dysfunctional uterine bleeding. Methods B-ultrasound guided radio frequency therapy was adopted in 121 cases of dysfunctional uterine bleeding with an exclusion of malignant lesions. Results The operation time was 6 min～12 min, with a mean of 8.5 min. No adverse effects were observed. The cure rate and marked effective rate were 88.4% (107/121) and 11.6% (14/121) in the 3rd postoperative month; the cure rate, marked effective rate and effective rate were 78.3% (36/46), 19.6% (9/46) and 2 1% (1/46) in the 24th postoperative month, respectively. Conclusions B-ultrasound guided radio frequency therapy in the treatment of climacteric dysfunctional uterine bleeding is simple and minimally invasive, being highly recommended.

objective To investigate the diagnosis and treatment of hepatic focal nodular hyperplasia(FNH).Methods Twelve cases with hepatic focal nodular hyperplasia from January 2003 to December 2006 in our hospital were reviewed retrospectively. Results Three cases had epigastric discomfort(25%),5 cases with elevated ALT(41.67%),3 cases with elevated AST(25%),2 cases with elevated AFP(16.67%),one patient was of positive HBsAg(8.33%).The rate of preoperative correct diagnosis made by ultrasound,CT and MRI was 0,20%and 25%respectively,there was no significant difference between CT and MRI.Final diagnosis was established by stlrgical resection and pathology in 11 cases and by needle biopsy in one case.All cases recovered and were followed-up with an average of 28 months.No recurrence was found in cases undergoing surgical resection. Conclusion The rate of correct preoperative diagnosis for FNH is low,definite diagnosis depends on pathologic examination.The prognosis is good,however,most patients in this series underwent resection because of possible malignancy especially in eases of cirrhotics.

It is therapeutically effective to apply hemopoietic growth factors to treat hemopoietic irradiation injuries, but for other tissues injuries, hemopoietic growth factors nearly do not work. At the same time, they are only suitable for the patients with severe and lower level acute radiation sickness (ARS). Besides, clinical therapeutic efficacy of marrow transplantation is not optimistic due to difficulties of marrow zygosity and severe complications such as graft versus host disease, radiation interstitial pneumonitis. Mesenchymal stem cells (MSCs) could secret hemopoietic growth factors, rebuild hemopoietic microenvironment and be easily transfected by exogenous gene, which also have low immunogenicity. At present, studies on MSCs application in the treatment of radiation injuries are at the early -stage, but the precise mechanism is not clear. However, the specific characteristics can make up the disadvantage of traditional treatment of acute radiation sickness, and the clinical application is wide.

Objective To study the correlation between dopamine and glutamate receptor NMDA NR_1 and NMDA NR_(2A),and to share the understanding of the mechanism of dopamine in the synaptic complex of inner hair cells.Methods Forty guinea pigs were divided randomly into four groups and the whole intacochlear perfusions were performed.The perfused cochleas were taken out as preparations 2 hours after perfusing,the contralateral cochleas were also taken out as the normal control group in the group perfused with artifical perilymph solutions.All the preparations were divided into 5 groups:①normal control cochleas;②perfused with artificial perilymph solutions;③perfused with artifical perilymph solutions containing 10 mmol/L dopamine；④perfused with artificial perilymph so lutions containing 30 mmol/L dopamine；⑤perfused with artifical perilymph solutions containing 50 mmol/L dopa mine.The semi-quantitive RT-PCR was used to observe the difference in the amount of glutamate receptor NMDA NR_1、NMDA NR_(2A).Results Dopamine inhibited the compound action potential(CAP),the increase of CAP threshold was observed and correlated with the contentration of dopamine in the perfusion solution.Regarding the amount of glutamate receptor NMDA NR_1 mRNA,there was no significant difference between group ① and group ② (P＞0.05).But a significant difference was observed the other 3 groups when compared to group ①(P＜0.05).No significant difference was detected among the 5 groups in the amount of glutamate receptor NMDA NR_(2A) (P＞0.05).Conclusion Dopamine may inhibit the cochlear auditory afferent nerve.The significant correlation between dopamine and glutamate receptor NMDA NR_1 was observed,the amount of glutamate receptor NMDA NR_1 decreased along with the increasing of the contentration of dopamine in the perfusion solution.And there was no significant correlation between dopamine and glutamate receptor NMDA NR_(2A).

Objective To investigate plasma pharmacokinetics profiles of compound betameth in guinea pig after postaurieal and systemic administrations,and to explore the possible pathway for postaurical injection. Methods 1 ml compound-betameth was injected postaurieally and intramuscularly into the guinea pig. Blood were samples obtained 0. 5,1,1.5,2,3,5,7 h and 1,2,4 w after the administration of contralateral sigmoid sinus blood and circulatory blood respectively. High performance liquid chromatography was used to dectet compound betameth in the samlowing postaurieal administration. The Cmax(peak concentration) in sigmoid sinus of postaurieal group was 2.56 and 3.03 higher than those in the contralateral and the systemic group. The AUC((area under the ct curve) was 2.41 postaurieal administration. The Cmax and AUC in postaurieal group were 0. 13 and 0. 32 higher than systemic group. Conclusion The postaurieal injection reached a higher concentration of drugs in the sigmoid sinus blood, and remained a lower concentration in circulatory blood.

Purpose:To investigate the clinicopathological characristics of colorectal mucinous adenocarcinoma (MUC),which is generally bel ieved to have a poor prognosis,in an attempt to assess ways in which the surgica l outcome can be improved. Methods:From 1994 to 2003,1 715 large intestinal cancer patient s underwent operation, among them, 197 patients were with MUC. The clinicopathol ogical parameters and prognosis of MUC and non-MUC were analyzed retrospectivel y. Results:There were no significant differences in sex , tumor si te and size. Patients with MUC had higher rate of serosal invasion (MUC:59.9% vs non-MUC: 35.1%) , invasive type lymph-node involvement (MUC:41.6% vs non-MUC 21.6%). Patients with MUC were of more advanced stage(D stage:MUC :44.1% vs non-MUC: 22.1%). Conclusions:Based on these findings , a more aggressive attitud e toward surgical intervention is recommended , including extensive lymph node d issection and the resection of adjacent organs that seems to be affected microsc opically , to improve the surgical outcome of this clinical entity.

Objective To investigate the effect of high intensity focused ultrasound(HIFU) on the immunity of patients with advanced primary liver cancer(PLC).Methods Forty cases of PLC admitted to our institution from Mar.2003 to Dec.2003 were included in this study.Patients were divided into 2 groups and received either HIFU or radio-frequency ablation(RFA) treatment randomly.CD3,CD4,CD8,CD4/CD8,NK,IL-2,TNF were chosen to assess the immune status before and after treatment.The results were compared statistically.(Results The) survival rate after HIFU was 80.0%,61.1%,42.9%,33.3% at 3 months,6 months,9 months and 1 year respectively,which was similar to that after RFA treatment.The changes of immunity parameters of CD3,CD4,CD8,CD4/CD8,NK,IL-2 and TNF were not significant after HIFU treatment.In addition,the differences of those parameters between HIFU group and RFA group were insignificant.Conclusion There are no detrimental effects on immunity in the early period after HIFU treatment.
