Objective To observe the curative effect of Weifuchun combined with Shenqifuzheng pills in the treatment of chronic atrophic gastritis.Methods 85 cases patients were divided into the control group of 42 cases and the treatment group of 43 cases.The control group were treated with omeprazole enteric -coated capsules and colloidal bismmth pectin,while the treatment group were treated with Weifuchun and Shenqifuzheng pills.The course of treatment was two months.The patients were treated by endoscopy and pathological review after the treatment,then the datas were comparedwith that before treatment.Results The total effective rate of the treatment group was 67.44%,which of the control group was 40.48%,the was statistically significant difference between the two groups (χ2 =6.22,P <0.05).The symptom scores of stomach tingling,stomach fullness,facial darkness,anorexia and melena in the two groups had statistically significant differences (t =6.14,P <0.05).Conclusion Weifuchun combined with Shenqi-fuzheng pills have good curative effect in the treatment of chronic atrophic gastritis.It should be popularized in clinic.

Objective To review the relationship between histone modifications and gastrointestinal cancer.Methods Literatures on histone modifications and the relationship between histone modifications and gastrointestinal cancer were collected and reviewed.Results Histone modifications played an important role in the establishment of gene silencing during tumorgenesis.DNA methylation and histone modifications might interact with each other and form a complex network to establish and maintain gene silencing.Restoring gene function silenced by epigenetic changes in cancer had the potential of 'normalizing' cancer cells,which was named epigenetic therapy.Epigenetic therapy was very promising in prevention and treatment of gastrointestinal cancer,but many unsolved issues remain which need to be addressed in future studies.Conclusion Histone modifications are associated with the pathogenesis of gastrointestinal cancer.Restoring gene function silenced by epigenetic changes may have a great role in the prevention and treatment of gastrointestinal cancer.

Objective To study the expression of three survivin splicing variants in gastric cancer and normal gastric mucosa and to evaluate relationship among the survivin variants' expression and proliferation, apoptosis in gastric cancer. Methods Real time quantitative RT-PCR was used to analyze survivin variants expression in 77 paired tumors and normal gastric mucosa in frozen samples at the mRNA level. The cell proliferation and apoptosis were measured by Ki-67 immunoln's to chemical analysis and TUNEL method in paraffin-embedded block of same cases, respectively. Results The sarvivin splicing variants were remarkably up-regulated in gastic cancers compared with those in normal tissues (P

Objective To investigate the correlation of ultrasonographic characteristics and pathologic features for malignant mullerian mixed tumor(MMMT)and determine the diagnostic value of ultrasonography.Methods The uItrasonographic features of 10 MMMTs were analyzed retrospectively and the sonographic findings were compared with histological results and discussed the correlation.Results The morphologic features of US and histology were well associated.Large,solitary lesion,ill-defined irregular shape,honeycombed heterogenous echo-pattern,scattered cystic areas and increased irregular peripheral/internal color flow were typical US findings.Logistic regression analysis showed the type of tumor liquefaction to be the most significant independent predictor of vascularity.Conclusions Ultrasonography is helpful for the diagnosis of MMMT,the uhrasonographic characteristics of MMMT are well correlated to its pathologic features.

Accumulating studies have proved that systemic inflammation is one of the important pathophysiologic mechanisms of heart failure. This article focuses on the sources of inflammation mediators and the causes of inflammation activation in heart failure including hemodynamic changes and oxidative stress, Toll-like receptors, microbial antigens and microorganisms, endotoxin hypothesis and neurohormonal activation. Furthermore, the effects of inflammation mediators such as cytokines and chemokines on heart failure are introduced. All lead to the conclusion that heart failure is a process with complex inflammation.

Objective To explore the biomechanical characteristics of the pharynx in patients with aspiration after radiotherapy for nasopharyngeal carcinoma (NPC).Methods Clinical data on NPC patients with dysphagia admitted between July 2011 and June 2015 were retrospectively analyzed.Twenty-three patients were found who had received videofluoroscopic swallowing studies (VFSSs) and whose pharyngeal pressure and upper esophageal sphincter (UES) relaxing were tested using high-resolution solid-state manometry (HRM).The cases were divided into an aspiration group and a non-aspiration group according to the VFSS results.Differences in biomechanical parameters between the 2 groups when taking food of different viscosity were compared.Results Patients with aspiration had significantly higher UES residual pressure when taking thick liquids (20.1± 14.3 mmHg) and paste (18.0± 14.3 mmHg) than patients not aspirating (9.3±9.2 mmHg and 7.2±8.9 mmHg for thick liquid and paste respectively).But no significant difference in average pharyngeal pressure between the two groups was observed.Conclusion Aspiration after radiotherapy may be correlated with increased UES residual pressure.

Objective To evaluate the reproducibility of quality intima-media thickness(QIMT) and quality arterial stiffness (QAS) technique in assessment of carotid under different measuring methods.Methods Between December 2012 and January 2014,carotid QIMT and QAS examinations were carried out in 30 health volunteers.QIMT and QAS indicators included IMT in QIMT and distensibility coefficient (DC),compliance coefficient(CC),stiffness index α(α),stiffness index β(β),pulse wave velocity(PWV) in QAS.The measurement employed unilateral/once,bilateral/twice,and unilateral/twice methods.Using intra observer and inter-observer variability,the reproducibility was compared between different QIMT and QAS indicators and measuring methods.Results Extremely high level of intra-observer reproducibility was found for both QIMT and QAS technique (ICC＞0.8).QIMT also showed an excellent inter observer reproducibility (ICC＞0.8).In contrast,the reproducibility of QAS technique varied in different indicators (PWV ＞ β ≈ α ＞ CC ＞ DC) and method ( unilateral/once ＞ bilateral/twice ＞ unilateral/twice).Conclusions QIMT measurement was highly reproducible.Whereas the reproducibility of QAS technique varied in different indicators and methods.Due to low reproducibility,the study result did not support the clinical application of DC indicator and unilateral/once method.

Aim To investigate the relationship between GABAA receptor or NMDA receptor and the amnestic effect induced by etomidate.Methods Amnestic model was established by intraperitoneal injection of etomidate(3 mg?kg-1) in mice before intracerebroventricular injection of different doses of bicuculline or NMDA,then the error times,step down latency and step through latency were observed and recorded in the step down test and step through test.Results Bicuculline(2,4 ?g) instead of NMDA by intracerebroventricular injection could decrease the error times and increase the step down latency and step through latency of amnestic mice in the step down test and step through test.Conclusion GABAA receptor rather than NMDA receptor may be an important target for the amnestic effect induced by etomidate.

Aim To observe the effects of ketamine on Na+,K+-ATPase,Ca2+-ATPase and NOSase activity in different cerebral cortex in convulsive mice.Methods The mice were randomly divided into blank group,normal saline(NS) group and ketamine 25 mg?kg-1 (KetⅠ),50 mg?kg-1(KetⅡ) group. The animals of blank group were killed directly.Convulsion was induced by intraperitoneally(ip) strychnine(1.5 mg?kg-1) in other groups,and correspond drugs were administered ip before five minutes.Action variety of mice was observed. Animals were killed on 30 minutes after strychnine injection.The activity of Na+,K+-ATPase,Ca2+-ATPase,TNOSase and iNOSase were assessed by spestrophotometric analysis in different cere-bral cortex(forehead,parietal and occipital area).Results Ketamine group could decrease mortality completely. The duration of tonic state in KetⅡ group was significantly shorter than that in KetⅠgroup.Compared with blank group,Na+,K+-ATPase and Ca2+-ATP ase activities were decreased in the group of NS and KetⅠ,and recovered normal level in the group of KetⅡ at parietal and occipital area. TNOS ase activity was decreased by 1/3 in KetⅡ group(P

Aim To investigate the relationship between amnestic effect of enflurane or isoflurane and NMDA receptor.Methods Amnestic model was established by intraperitoneal injection of enflurane(0.4 ml?kg-1)or isoflurane(0.3 ml?kg-1)respectively in mice before intracerebroventricular injection of different doses of NMDA(25,50,75 ng),then the error times,step down latency and step through latency were observed in the step down test and step through test.Results NMDA(50,75 ng)by intracerebroventricular injection could decrease the error times,and increase the step down latency and step through latency of amnestic mice induced by enflurane or isoflurane in the step down test and step through test.Conclusions NMDA by intracerebroventricular injection can improve amnestic effect of enflurane or isoflurane partially.NMDA receptor may be an important target for amnestic effect of enflurane or isoflurane.
