Objective To explore the nursing effect evaluation of vacuum sealing drainage based latissimus dorsi bridge free skin flap to repair refractory wound. Methods Thirty-seven cases of patients with intractable wounds were chosen as the observe group from January 2009 to January 2012, and 26 cases accepting the traditional way of wound care with intractable wounds were selected as control group from January 2006 to December 2008. Control group adopt conventional methods wound and the observation group accepted VSD accessories line wound negative pressure closed drainage before the wound phase 2 latissimus dorsi bridge free skin flap repairment. After treatment, the dressing time, interval and dressing change, the time of hospitalization were observed, and the nursing effect were compared after skin flap to repair for 8 days and 16 days between patients of two groups. Results The dressing time and hospitalization days in observation group after treatment were significantly less than that in control group ( <0.05), the number of dressing have significantly shortened compared with control group ( <0.01), and the dressing change interval in control group had significantly difference ( <0.01) . The effect of 2 patients in control group after skin flap to repair was poorer, but the observation group did not appear significant necrosis. Compared the good rate of two groups, the observation group patients was significantly higher than control group ( <0.01) . The therapy good rate of observation group was significantly better than that of control group (<0.01) . Conclusion The negative pressure closed drainage based ascending latissimus dorsi bridge free skin flap repairment has contributed to cure the refractory wound recovery significantly.

AlM: To compare the effects of external approach microsurgery and conventional external approach surgery for retinal detachment ( RD) .METHODS: From January 2010 to January 2013, 60 patients (60 eyes) in our hospital were randomly divided into experimental group (29 cases, 29 eyes) and control group ( 31 cases, 31 eyes ) , the external approach microsurgery and conventional external approach surgery were performed respectively ( by the same skilled doctor ) . Retinal reattachment rate, visual acuity improvement rate and operative time were compared between two groups.RESULTS:lt cost shorter time for the external approach microsurgery than that of conventional external approach surgery ( P = 0. 0087 ). The once successful retinal reattachment rate in experimental group was 93% ( 27 cases ) , which was higher than that in control group (90%, 28 cases), there was no statistical difference. The vision improvement rate in control group was 86% ( 25 cases ) , compare to 90% ( 28 cases ) in experimental group, there was no statistical differences. CONCLUSlON: No statistical differences showed in visual acuity improvement and the once retinal reattachment rate between the two groups for rhegmatogenous retinal detachment. However, it is believed that external approach microsurgery could be faster, easier to learn with satisfactory effect.

Objective To evaluate the renal involvement and therapeutic effect on ANCA-associated vasculitis(ASV) . Methods Fifty-six cases were diagnosed as ASV from Oct 1997 to Mar 2001. Among them, 21 cases received renal biopsies. According to disease activity and severity, Use following treatment protocols were choosed: (1) double pulse therapy; (2) single pulse therapy; (3) oral prednisone and/or low dose of CTX; (4) blood purification technique and/or immunosuppressive therapy. Remission rate was also analyzed. Results 96. 4% of case suffered with renal involvement. 91. 1% with acute renal failure, 96.4% with severe renal failure, 98. 2% with multiple organs involvement. The mortality was 19. 6% and the remission rate 67. 9%. 12. 5% of cases lost follow-up. ConclusionsRenal involvement is common and serious in ASV patients. Individualized and early therapy, as well as valuable urgent renal biopsy are necessary. To those who have entered ESRD, immunosuppressive agents could be used to decrease the extra-renal complication.

PURPOSE: The growth hormone receptor(GHR) is essential for the actions of growth hormone on postnatal growth and metabolism. GHR transcripts are characterized by the presence of disparate 5'untranslated exons. In contrast to L1 transcript, factors regulating the expression of the GC rich L2 transcript have remained unidentified. The purpose of this study is in order to characterize the mechanisms regulating expression of the L2 transcript in the murine GHR gene METHODS: Transient transfection experiments including deletional analysis and co-transfection assay were performed to find a region containing promoter activity in the L2 5'flanking sequence using BNCL2(mouse liver) cells, CV-1(African green monkey kidney) cells, HRP.1 trophoblasts and Drosophila Schneider(SL2) cells. Sequencing analysis was performed to find the region contained consensus binding sites for transcription factors. Standard gel shift(Electrophoretic mobility shift assay, EMSA) and supershift analysis using liver nuclear extracts was performed to establish proteins(transcription factors) bound this regulatory element. RESULTS: The 5'flanking region of the L2 untranslated region(UTR) exhibited promoter activity in BNCL2(mouse liver), CV-1(monkey kidney) cells and HRP.1 trophoblasts. Deletional analyses indicated the presence of a Sp binding site important for transcription of the L2 UTR and localized the major regulatory region within 75 bp of the 5'transcription start site. Sequencing analyses revealed the region contained consensus binding sites for the Sp family of transcription factors. EMSA and supershift EMSA revealed that in mouse liver nuclear extracts that Spl and Sp3 bound to this cis-element. Functional studies in Drosophila SL2 cells and BNCL2(mouse liver) cells established the ability of Sp3 and Sp1 to stimulate transcriptional activity via this cis-element. Functional studies in Drosophila SL2 cells demonstrated a functional interaction between Sp3 and Sp1 at this DNA-binding site. CONCLUSION: Sp family transcription factors play a role in regulation of L2 transcript gene expression in the 5'flanking region of the murine GHR gene.
