Objective Uterine epithelial cells were isolated from pregnant mice and cultured in vitro , and exam-ined the effect of CD82 on the expression of integrin αV,β3, E-cadherin and β-catenin in the cells.Methods The uter-ine epithelial cells were primarily isolated from pregnant mouse uterus .The recombinant adenovirus containing mouse CD 82 gene which had been constructed in our lab infected the uterine epithelial cells .Immunocytochemistry was used to detect the protein expressions of integrin αV,β3, E-cadherin and β-catenin in the uterine epithelial cells , which were infected with CD82 adenovirus or not .Results 1.The purity of primary cultured cells was (93.2 ±0.6)%.2.The transfection efficiency of CD82 recombinant adenovirus was ( 92 ±4.5 )%.The adenoviral particles carrying CD 82 gene indeed ex-pressed CD82 gene and protein in the primary uterine epithelial cells after 24 hours or 48 hours.3.The uterine epithelial cells of pregnant mice on d4 expressed integrin αV, β3, E-cadherin and β-catenin.4.In contrast to the control group, when CD82 adenovirus infected cells , the uterine epithelial cells of pregnant mice on d 4 increased the expression of integrinαV,β3 and β-catenin protein, had no significant changes of E-cadherin.Conclusions CD82 may have effect on the ex-pression of integrin αV,β3 and β-catenin in mouse uterine epithelial cells before implantation .

Objective In order to provide the basis for establishment of food allergy models , we compared the differences of sensitivity and alterations of intestinal flora of food allergy models in two strains of mice .Methods Forty 4-5-week old female BALB/c and Kunmimg mice were divided into control group ( n=10) and food allergy goup ( n=30), respectively.Ovalbumin (OVA) was injected to the mice to establish food allergy models .Serum OVA-specific IgE of the mice was assayed by ELISA .The jejunum tissue was examined by pathology with HE staining .The changes of fecal flora were detected by denaturing gradient gel electrophoresis (DGGE).Results (1)Among the sensitized 60 mice, OVA-sIgE levels were significantly increased in 27/30 BALB/c mice and 21/30 KM mice compared with those of control groups(P<0.001).Moreover, there were more evident inflammatory cell infiltration , epithelial cell shedding and cytolysis in the jejunal villi of BALB/c mice than those of KM mice.(2) After food allergy modeling, there were significant changes of intestinal flora in the BALB/c mice (P<0.001), while only significant change of evenness was found in the KM mice (P<0.05).(3)There were changes of abundance , Shannon index and evenness of intestinal flora in the model groups of BALB/c and KM mice.Conclusions BALB/c mice are more sensitive to OVA allergy than KM mice .The composition of intestinal flora is different among different strains of mice .The changes of intestinal flora after OVA challenge in BALB /c mice are more obvious than those in KM mice .

Objective To discuss the clinical characteristics of diagnosis and treatment of primary gastric malignant lymphoma (PGML). Method The data from 34 PGML medical records were reviewed retrospectively between January 2001 and May 2008. Results There were 23 cases of B-cell malignant lymphoma, 7 cases of T-cell malignant lymphoma, and 4 cases of non-B and non-T small cell lymphoma. Confirmed by pathology, 14 cases of them had metastasis to lymphoid nodes and 5 cases had invaded the organs nearby. All of these 34 cases had gastroendoscopy before operation. Conclusions PGML has no specific manifestation, and the definitely diagnostic rate of gastroendoscopy is low. The surgical resection is the major therapy.Operative pattern,the size of tumor,pathological stage can predicate the prognosis for PGML.

Objective To investigate the expression and significance of Insulin like growth factor-ⅡmRNA binding protein3 (IMP3) in gastrointestinal stromal tumors (GIST). Methods One hundred and fifteen cases of GIST were subjected to immunohistochemical staining for IMP3 (SP method) and ki67 (iVisionTM method ). The relationship between IMP3 expression with clinicopathologic parameters and Ki67 proliferation indexes were analyzed. In situ hybridization detection of IMP3 mRNA was performed in 20 cases of GIST positive. Results The expression rate of IMP3 was 56.2%(65/115) in GIST positive. A significant correlation can be found between IMP3 expression and tumor of infiltration , coagulative necrosis , metastasis , nuclear atypia , diameter , mitotic count , risk grade of NIH (P < 0.05), while there was no significant correlation between IMP3 and gender, age, primary location, categories of cell type (P>0.05). There was positive correlation of IMP3 expression and Ki67 labeling indexes by Spearman analysis. Positive expression with IMP3 can be observed in 3 cases of recurrence.It may play important role in invasive and development and may be an important factor of prognosis in GIST.

The use of flaps for plastic and reconstructive surgery is very popular today.More and more surgeons have realized that the blood supply plays an important role in the design and survival of flaps.After Ian McGregor and Ian Jackson first introduced the axial flaps into clinics,Mathes divided the flaps into two types in 1981,the fasciocutaneous perforator flaps and musculocutaneous perforator flaps.In 1989,the concept of perforator flap was first brought into clinical practice.With the development of microsurgery and anatomy,the epidermis of human skin is divided into areas based on the vascular anatomy.A new century of musculocutaneous perforator flaps has been established.The terminology,classification,characteristics and application of musculocutaneous perforator flaps are described in this paper.

To evaluate the neuroprotective effect of nerve growth factor ( NGF ) on acute angle-closure glaucoma patients after trabeculetomy.METHODS: Patients with viral keratitis who underwent trabeculectomy in treatment of acute angle - closure glaucoma in Xiamen Eye Center of Xiamen University from December 2011 to October 2013 were selected and completed the treatment, 61 eyes of 45 cases were followed up. The treatment group of 23 cases (32 eyes) with acute angle-closure glaucoma patients were treated by NGF gel for 3mo after trabeculetomy, while in the control group 22 cases (29 eyes) were treated by normal saline replaced NGF. All patients were followed up for at least 12mo, visual acuity, perimetry, retinal nerve fiber layer ( RNFL) thickness and cup/disc ratio of the patients were followed up during the treatment. The safety of topical use of NGF gel was also evaluated.RESULTS:ln all patients, the intraocular pressure ( lOP) was successfully controlled under 21mmHg and the visual acuity was markedly increased in the affected eye after trabeculectomy. Compared with control group, the postoperative lOP and visual acuity had no significant differences in treatment group (P>0. 05). The average light sensitivity of perimetry and mean defect were better than that in control group postoperative 6 and 12mo; The results of optical coherent tomography ( OCT ) and Heiderburg Retina Tomography ( HRT )-Ⅲ showed that RNFL thickness was significantly greater than that in control group, while cup/disc ratio significantly less than that in control group postoperative 6 and 12mo. Ocular surface damage, corneal endothelium to reduce and other eye complication were no observed in treatment group.CONCLUSlON:Acute angle-closure glaucoma treated by NGF gel after operation is effective and safe.

In this study, solvent evaporation method was used to preparing baicalin ethylcellulose microspheres for intranasal administration. The prepared microspheres were round with certain rough surface. The average drug loading and entrapment efficiency was (33. 31 ± 0. 045)% , (63. 34 ± 0. 11)% , respectively. As the characteristic crystalline peaks of baicalin were observed in the microspheres sample, the result of X-ray diffractometric analysis indicated that the baicalin was present in crystalline form after its entrapment in ethylcellulose matrix. By investigating the thermogram of microspheres sample, it was found that endothermic peak of baicalin was shifted from 211. 8 °C to 244. 2 °C and associated with the first broad endothermic peak of ethylcellulose. This could confirm that baicalin was loaded into ethylcellulose, nor simply physical mixture. The powder flowability test exhibited that the specific energy of microspheres was 3. 57 mJ . g-1 and the pressure drop was 2. 22 mBar when air kept the speed of 2 mm . s-1 through the powder bed with the force was 15 kPa. The consequence of the baicalin in vitro released from microspheres showed that the pure baicalin sample displayed faster (90%) release than microspheres sample (75%) in 7 h. Fitting model for release curve before 7 h, the results showed that the pure baicalin sample and the microsphere sample accorded with first order model (R2 = 0. 990 4) and Riger-Peppas model(R2 = 0. 961 2), respectively. Ex vivo rabbit nasal mucosa permeability experiment revealed that the value of cumulative release rate per unit area of the microsphere sample was 1. 56 times that of the pure baicalin sample. This provided the foundation for the in vivo pharmacokinetic study.
