ObjectiveTo evaluate the therapeutic effect of endoscopic full-thickness resection (EFTR) for gastric stromal tumors.MethodsA total of 33 patients with gastric stromal tumor orgination from deep muscularis propria layer received EFTR from January 2010 to July 2011.The effectiveness and safety of EFTR were compared with those of other 34 patients with gastric stromal tumor origination from muscularis propria layer who underwent endoscopic submucosal dissection (ESD).ResultsExcept in 2 patients with lesions larger than 3.0 × 3.0 cm,EFTR was successful in others 31 patients,who recovered well and had no recurrence during the follow-up within 12 months.There were no significant differences in resection rate,incidence of complications,body temperature,white blood cell counts or recovery time between 2 procedures (P > 0.05 ).However,the number of clips used in EFTR ( 7.0 ± 3.5 vs.4.9 ± 3.1,P =0.013 ) and postoperative fasting days (3.4 ± 1.5 vs.2.0 ± 1.0,P =0.001 ) were significantly higher than those of ESD procedures.ConclusionEFTR is effective and safe for gastric stromal tumors with no higher risk than ESD,but it is more complex technically.EFTR can be used as an expanding method of ESD in endoscopic treatment of gastric stromal tumors.

Objective:To investigate the Foxp3 expression in murine model of type 1 diabetes mellitus and the effects of Foxp3 in the pathogenic mechanism of type 1 diabetes mellitus.Methods:Type 1 diabetes mellitus of mouse was induced by STZ.The Foxp3 expression in the spleen cells was detected at the mRNA level by RT-PCR and at protein level by Western blot.The percentage of CD4+CD25+ Treg cells in the spleens were detected by Flow cytometry.Results:The expressing levels of Foxp3 mRNA and scurfin in the model group was higher than those of control group within the first week after induction,but the expressing level of Foxp3 mRNA and Scurfin began to decrease on day 7 and were lower than those of control group on day 30.The percentage of CD4+CD25+ Treg cells in model group was similar with that of control group within the first week after induction,but after day 7,the percentage of CD4+CD25+ Treg cells in model group began to get lower than contol group.Conclusion:The expressing level of Foxp3 is decreased,then the proportion of CD4+CD25+ Treg cells is decreased accordingly,which may contribute to the pathogenic mechanism in type 1 diabetes mellitus.

OBJECTIVE:To evaluate the efficacy and toxicity of paclitaxel combined with cisplatin in the treatment of advanced non-small cell lung cancer(NSCLC) by weekly-,biweekly- and three-weekly-regimens.METHODS:180 patients who had been confirmed by pathology and cytology as having NSCLC(Ⅲ~Ⅳstage) were enrolled into the study and divided to three groups:Biweekly - regimen(n= 60):paclitaxel 80 mg?m~(-2) plus cisplatin 40 mg?m~2 ivgtt on day 1 and day 8 in every 21 days;Weekly- regimen(n= 60):paclitaxel 55 mg?m~(-2) plus cisplatin 30 mg?m z ivgtt on day 1,8,and 15 in every 28 days;Three - weekly regimen(n = 60):paclitaxel 160 mg?m~(-2) plus cisplatin 80 mg?m~(-2) ivgtt on day 1 in every 21 days.Serum concentrations of paclitaxel at 3,12,24 h after administration were determined,and the efficacy and toxicity after two- cycle treatment were evaluated.RESULTS:The overall response rates of weekly-,biweekly -and three weekly regimens were 43.1%,35.8%and 34.0%respectively,showing no statistical differences among groups,but the incidence of main toxicities of biweekly-regimen was lower as compared with the other regimens.CONCLUSION:Biweekly -regimen is optimal for the treatment of advanced NSCLC with mild toxicity,which deserves to be applied in clinical practice.

Xiyanping is used to treat infectious diseases with antibiotics in clinic. The aim of this study is to investigate the mechanism of Xiyanping through studying the effect of the combination of Xiyanping with Cefazolin on the chemotaxis and phagocytic function of peripheral blood neutrophils in mice. Ten healthy mice were in control group. Forty healthy mice in experimental group were infected with staphylococcus aureus, and were randomly divided further into four groups, i. e. model group, Xiyanping group, Cefazolin group and combination group (Xiyanping with Cefazolin). Mice in the control group and model group were given normal saline (NS) through abdomen while those in other groups were given Xiyanping, Cefazolin, and Xiyanping with Cefazolin, respectively. The chemotaxis of peripheral blood neutrophils was detected with the transwell method, and the phagocytic function of peripheral blood neutrophils was analyzed with flow cytometry (FCM). In the present study, there was no significance on the chemotactic index of peripheral blood neutrophils in all the groups (P > 0.05). The actual phagocytotic rate and index of peripheral blood neutrophils in the blank group, Xiyanping group, and the combination group were significantly higher than those of the model group and Cefazolin group (P < 0.05). However, those were not significant in the blank group, Xiyanping group, and the combination group (P > 0.05) or between the model group and Cefazolin group (P> 0.05). Our results suggested the combination of Xiyanping and Cefazolin could enhance the therapeutic effect by improving the phagocytic function of peripheral blood neutrophils.

When MR image's area is too small compared with the whole picture, the use of the current auto-window algorithms usually gets poor clarity and contrast. In order to address this problem, an improved auto-window algorithm is proposed in this paper and can solve the problem effectively and get clear and rich layers of MR images quickly and easily.
