Objective To investigate clinical feature,diagnosis and prognosis of eosinophilic gastroenteritis(EG),and to analyze the causes of misdiagnosis.Methods Eleven children diagnosed as EG were studied.Their history,clinical manifestations,laboratory tests and endoscopies and treatment,follow-up data were analyzed.The data were analyzed by SPSS 10.0 software.Results 1.The children with EG usually had abdominal pain(5 cases),diarrhea(7 cases),hemafecia(5 cases) and sometimes with fever(2 cases).2.EG and allergy in children was closely related with disease(54.55%).3.Peripheral blood eosinophil(EOS) count increased significantly,and declined when symptoms eased(18.18%).4.Endoscopic manifestations were not specific,the mucosa could see sheet erosion,shallow ulcers,congestive spots or bleeding spots,mainly in antrum,duodenum,terminal ileum,ileocecal junction.The biopsy showed that a large number of EOS infiltration.5.Imaging were not specific,CT or gastrointestinal barium meal examination did not show special often(90.91%).When muscular wall was affected(9.09%),imaging presentations of EG could be partly obstructive.6.Glucocorticoid therapy could relieve symptoms and EOS.Symptoms probably recured by good prognosis.7.EG was a self-limiting allergic diseases,although the attack may be repeated.After long-term follow-up,most had good prognosis and without malignant.Conclusions Clinical and endoscopic presentations of EG are not specific,therefore the presence of EOS in gastrointestinal mucosa strongly indicate the diagnosis.It was easy to misdiagnosis.Biopsy pathology and cli-nical characteristics are the key to diagnosis.

Objective To investigate the roles of ulinastatin in improving coagulation function and inhibiting fibrolysis in neohepatic phase in liver transplantation. Methods Forty patients who were to undergo liver transplantation were randomly divided into ulinastatin group(experiment group,n=20) and placebo group(control group,n=20).Platelet,prothrombin time(PT),activated partial thromboplastin time(APTT) and fibrinogen(Fg) were measured at induction,anhepatic phase(10 min after clamping),neohepatic phase(5 and 60 min after unclamping) and the end of operation.Coagulation index(CI) of thromboelastogram(TEG) was monitored,and the volumes of blood loss,red blood cells infusion,fresh frozen plasma infusion and cryoprecipitate infusion were recorded. Results Five min after unclamping,the number of patients with CI

The high mobility group A2 (HMGA2),one of non-histone chromatin protein,can specificly bind to AT-rich DNA sequences by its AT-hook and work as oncofetal gene and architectural transcription factor.HMGA2 expresses in almost all kinds of malignant neoplasms,which is closely related to the formation,development and poor prognosis of the neoplasms.HMGA2 plays a very important role in every biological process including cell proliferation,cell cycle,stem cell self-renewal,epithelial-mesenchymal transition and DNA damage repair.It is of great significance to study the effect and mechanism of HMGA2 in neoplasms.

Salinomycin is a chemotherapeutic drug commonly used to inhibit the growth of tumor and specifically kill the cancer stem cells (CSC).The anti-cancer effect of salinomycin has attracted extensive attention at home and abroad,whihc is realized by inducing cancer cell apoptosis,suppressing cancer cell proliferation and invasion and reducing drug resistance.

Sirtuin 1 (SIRT1),the Ⅲ class deacetylation enzyme,is a kind of NAD + dependent histone deacetylation enzyme.The role of SIRT1 in tumor has the duality.It can inhibit inflammation,tumor angiogenesis and interact with tumor related gene to inhibit tumor development.However,it can also regulate tumor related genes,and epithelial-mesenchymal transition,promote tumor cell proliferation and tolerance of radiotherapy and chemotherapy,and maintain the stemness of cancer stem cells to promote tumor proliferation,invasion and metastasis.

Objective To investigate the expression and signification of B-cell lymphoma/leukemia-2(bcl-2),bax and ER proteins in epithelial cells in different depth of adenomyosis.Methods Expression and correlation of bcl-2,bax and ER proteins were detected by immunohistochemistry staining in 36 adenomyosis cases with superficial (＜ 1/2 depth of penetration) and deep (≥ 1/2 depth of penetration)ectopic endometrium and eutopic endometrial tissues matched with 30 cases with benign ovarian tumor,uterine septum,pelvic floor dysfunction without adenomyosis as controls.Results (1) The expression of ER protein in superficial and deep ectopic tissues (5.04 ±0.24,4.91 ±0.16) were found significantly lower than 6.06 ± 0.36 in eutopic tissues (P ＜ 0.01) and higher than 3.70 ± 0.58 in control group (P ＜ 0.05).There was no statistical difference of ER expression in superficial and deep ectopic endometrium (P ＞ 0.05).(2) The level of bcl-2 protein of 5.6 ± 0.4 in superficial and 6.0 ± 0.3 in deep myometrium of ectopic tissues were significantly higher than 3.6 ± 0.4 in eutopic tissues and 1.9 ± 0.4 in control group (P ＜ 0.01).(3) The level of bax protein of 3.50 ± 0.28 in superficial and 4.80 ± 0.29 in deep myometrial ectopic and 4.43 ± 0.37 in eutopic tissues were significantly lower than 6.18 ± 0.65 in control groups (P ＜0.05).The expression of bax in superficial myometrium is significantly lower than deep myometrium in ectopic tissues (P ＜0.01).(4) The positive correlation between the expression of ER and bcl-2 protein at superficial myometrium of ectopic tissues (r =0.720,P ＜ 0.01).And there was no significant correlation with the expression of ER and bax protein at superficial myometrium (r =0.008,P ＞ 0.05).As well as,there was not significant correlation with the expression of bcl-2,bax and ER protein at deep myometrium (r =0.089,r =-0.023,P ＞ 0.05).The expression of bax protein in ectopic endometrium was positive correlation with the depth of adenomyosis penetration (r =0.736,P ＜ 0.01).There was positive correlation between the expression of ER and bcl-2 protein at normal endometrium (r =0.453,P ＜ 0.05).And there was negative correlation between the expression of ER and bax protein at control group (r =-0.514,P =0.05).Conclusion The bax protein expression of ectopic endometrium in deep adenomyosis was higher than superficial adenomyosis.

Parkinson's disease(PD) is a common neurodegenerative disorder with no effective protective treatment,characterized by a massive degeneration of dopaminergic neurons in the substantia nigra(SNpc) and the subsequent loss of their projecting nerve fibers in the striatum.The major neurochemical manifestation of this disorder is the loss of the neurotransmitter dopamine(DA) in the striatum as a result of the progressive degeneration of the dopaminergic neurons in the substantia nigra.There have been significant progresses in recent years reporting on the use of mesenchymal stem cells(MSCs)in gene therapy,with specific application towards PD.MSCs,a kind of multipotent adult progenitor cells,are considered as a useful vehicle for cell and gene therapy because of their multiple differentiation potentiality and self-transplantation.The present study was focused on treating rat model of PD using human tyrosine hydroxylase gene(hTH),human aromatic L-amino acid decarboxylase gene(hAADC) and human GT Pcyclohydrolase I gene(hGCH-I) engineered MSCs,in order to provide a better understanding about the application of these cells in the therapeutic benifit of PD.The gene of hTH,hAADC and hGCH-I were introduced via recombinant adeno-associated virus(rAAV) infection into the MSCs in vitro.The genetically modified MSCs expressing hTH,hAADC and hGCH-I were transplanted into the striatum of PD rat models.The behavior,the nigra-striatal level of DA and its metabolite were detected.The results of present study were shown as follows:hTH,hAADC,hGCH-I and LacZ gene were transfected into MSCs with adeno-associated virus vectors.The HEK293 packaging cells(ATCC) were transfected with the plasmids of pAAV-hTH,pAAV-hAADC,pAAV-hGCH-I,pAAV-LacZ,pAAV-RC,pHelper by using calcium phosphate precipitation.Titer was detected using HT1080 cells.Viral particles were collected and used to infect MSCs.The purified modified MSCs expressing the three kinds of genes were selected separately and were grafted in the striatum of the PD model rats in the lesion side.The MSCs genetically modified suvived well 12 weeks after transplantation.The improvements of the behavior were observed every week after transplantation.Compared with the control group,the rounds of asymmetric rotation after apomorphine administration decreased in the groups double or triple genes engineered MSCs grafted(p
