Human kerotinocyte growth factor (hKGF) gene amplified by PCR was inserted into the shuttle vector pAdTrack-CMV to get the recombinant plasmid pAdTrack-CMV-hKGF, which was linearized with Pme I and transferred into Escherichia coli BJ5183 containing the adenoviral bone plasmid pAdEasy-1 to obtain the recombinant adenoviral plasmid pAdEasy-hKGF. The recombinant adenoviral plasmid was then transfected into HEK-293 cell lines via Lipofectamine 2000 to package and amplify the recombinant adenovirus containing hKGF gene detected by PCR. The recombinant adenovirus produced could effectively infect HaCat cells. The result of Western blotting showed that HaCat cells infected with the recombinant adenovirus expressed and secreted hKGF protein.

Objective To investigate the clinical characteristics and treatments of endometrioid carcinoma patients with preoperative diagnosis of endometrial hyperplasia.Methods From 2005 to 2010, 404 patients were diagnosed with endometrioid carcinoma after hysterectomy.Among these patients,44 of them were diagnosed atypical endometrial hyperplasia(AEH) preoperatively.Retrospectively analysis the characteristics of these patients with SPSS13.0.Results Among the 44 cases, all of them were grade G1 disease, and 39 of them received comprehensive staging surgery.14(32%)young cases preserved bilateral ovaries.9 cases(20%) were given adjuvant radiology.No recurrence was detected during the median follow up of 52 months.Compared to the premenstrual group, although no statistical difference was detected, more patients with risk factors of deep myometrium invasion(4/22 vs 1/22) and lymph-vascular space invasion(LVSI, 3/22 vs 0/22) in the postmenstrual group.Compared to the patients who diagnosed with endometrioid cancer(EC) preoperatively, there are more patients with grade G1(P=0.000), fewer patients received adjuvant chemotherapy(P=0.003) and fewer recurrence(P=0.019) in AEH group.Conclusions The endomtrioid cancer patients who diagnosed with atypical hyperplasia preoperatively have better prognosis.Hysterectomy with bilateral ovaries preserved is acceptable in young patients.Post menopause patients have more risk factors of deep myometrium invasion and LVSI.

ObjectiveTo evaluate the effect of rehabilitation nursing in the peri-operative period of the first-stage combined anterior-posterior approach surgery in the sacral tumor resection.Methods15 patients with sacral tumor received psychological intervention, gastrointestinal preparation, exercises of perineum sphincter contraction and relaxation training before the operation. Changes of patients' vital signs and nerve function were observed after the operation, and rehabilitation training and instruction were performed.ResultsAll cases were followed up for 2~37 months. Except one case died of tumor transfered to lung, all of other cases had a satisfactory curative effect in the near future, and their local symptom released and the functions of urination and defecation were kept well.ConclusionRehabilitation nursing in the peri-operative period plays an important role in surgical treatment of sacral tumor. It affects the rehabilitation and function restitution obviously and can reduce the occurrence of complication effectively.

Acta Pharmaceutica Sinica 2010;45(1):55-59
This study is to investigate the effect of recombinant hFGF-10 adenovirus on the proteome of HaCat cells, and to speculate further the possible mechanism of the effect of hFGF-10 on HaCat cells via differentially expressed proteins identified. Two-dimensional gel electrophoresis (2-DE) combined with tandem time-of-flight mass spectrometry was applied to identify the differentially expressed protein spots on the 2-DE maps of the whole-cell proteins from Ad infected and rAd-hFGF-10 infected HaCat cells. The mRNA and protein levels of the differentially expressed proteins were confirmed with semi-quantitative RT-PCR and Western blotting. The results showed that the 2-DE maps with high resolution were obtained, and four selected differentially expressed proteins involved in cell apoptosis, cytoskeleton regulation and protein degradation were identified with MALDI-TOF/TOF. The mRNA and protein levels of one of the differentially expressed proteins, VDAC2, were up-regulated in HaCat cells infected with the recombinant hFGF-10 adenovirus. The differentially expressed protein, VDAC2, may be related to the bioactivities of hFGF-10.

An experimental model of rhegmatogenous retinal detachment (RRD) in rabbits was established to simulate the pathophysiologic condition of human RRD. 24 rabbits were randomly divided into 3 groups and underwent vitrectomy with a vitrector and/or retinotomy with a Charles flute needle, with 12 in group I (vitrectomy and retinotomy), 7 in group I (retinotomy) and 5 in group III (vitrectomy). All animals underwent follow-up examinations with direct and indirect ophthalmoscopy and fundus photography 12 h and day 1, 3, 5, 7, 10, 14, 21, and 28 after the procedure(s). Retinal changes were recorded. As a result, 10 RRDs were successfully established in group I. Direct and indirect ophthalmoscopy and fundus photography demonstrated typical features of RRD. No RRD developed in group II and III. It was concluded that the experimental rhegmatogenous retinal detachment produced in a rabbit model after vitrectomy with retinotomy in this study was a convenient and reliable one. This RRD model mimicked the typical pathophysiological changes in humans.

To study the role of anti- C. albicans IgY and serum in protection of C. albicans infection of several animal models. To develop three animal models of C. albicans infection: a burned rat model of C. albicans infection, a mouse model of vaginal candiasis and a immunosuppression mouse model of C. albicans infection. And we compared the contribution of anti- C. albicans IgY and serum to the clearance of the C. albicans in three animal models of C. albicans infection. Anti- C. albicans IgY can protect against C. albicans infection in a burned rat model of C. albicans infection and a mouse model of vaginal candidiasis. The serum can effectively protect the mice from disseminated candidiasis in a immunosuppression mouse model. Humoral immunity component involving anti- C. albicans IgY and serum protect against C. albicans infection in a burned rat model of C. albicans infection ,a mouse model of vaginal candidiasis and a immunosuppression mouse model of C. albicans infection.

AIM: To investigate the effects of bone morphogenetic protein 7 ( BMP-7 ) on the expression of transcription factor E2A and inhibitor of differentiation 2 (Id2) in the renal tubule epithelial cells(NRK-52E)exposed to high glucose, and to explore its possible mechanism of improving renal tubular fibrosis induced by high glucose.METH-ODS:The NRK-52E cells were divided into control group, high glucose (HG) group and high glucose with different doses of BMP-7 (10μg/L and 20μg/L) group.The cells in HG group and BMP-7 group were cultured for 12 h, 24 h and 48 h. The protein expression of Id2, E2A, E-cadherin,α-smooth muscle actin (α-SMA) and collagen-I was detected by Western blot.In addition, the mRNA expression of Id2 was detected by real-time PCR.RESULTS:Compared with control group, the mRNA and protein levels of Id2 and the protein level of E-cadherin were down-regulated, while the protein levels of E2A,α-SMA and collagen-I were up-regulated in HG group (P<0.05).Compared with HG group, the mRNA and pro-tein levels of Id2 and the protein level of E-cadherin were significantly up-regulated, while the protein expression of E2A,α-SMA and collagen-I was significantly down-regulated in 20 μg/L BMP-7 group ( P<0.05 ) .The correlation analysis showed that the Id2 protein level was negatively correlated with the E2A protein level (P<0.05).CONCLUSION:BMP-7 may intercept the process of renal tubule fibrosis induced by high glucose via promoting the expression of Id2 and inhibi-ting the expression of E2A at protein level.
