RESUMO

<p><b>OBJECTIVE</b>To evaluate the use of Delorme procedure for full-thickness rectal prolapse.</p><p><b>METHODS</b>A series of 25 patients with full-thickness rectal prolapse were treated by Delorme procedure in four institutions between March 2005 and June 2010. The clinicopathological data were analyzed retrospectively.</p><p><b>RESULTS</b>There were 9 males and 16 females. The mean age was 52(46-72) years old. All the procedures were successfully performed. There were no perioperative deaths. The mean operative time was 65(45-150) min. The intraoperative bleeding was 58(20-200) ml. The mean length of hospital stay was 8.5(5-14) days. Anastomosis dehiscence occurred in 1 patient at post-operative day 7 who was managed under anesthesia. Minor complications occurred in 8(32%) patients, including urinary retention(n=3), intractable pain(n=1), and bowel obstruction(n=4). The follow up time ranged from 2 to 6 years with a median of 3.5 years. Prolapse recurrence was observed in 1(4%) patient during the follow up. The remission rates of fecal incontinence, constipation, bleeding were 37.5%(6/16), 45.5%(5/11), and 15.4%(2/11), respectively. The Wexner incontinence score significantly decreased (median, 5.0 vs. 9.0, P<0.01). The resting pressure and maximum squeeze pressure increased significantly after surgery, while the initial volume and maximal tolerance volume decreased significantly(All P<0.01).</p><p><b>CONCLUSIONS</b>Delorme procedure is safe and easy to perform. The anorectal function is improved after surgery. Therefore it should be considered the procedure of choice for rectal prolapsed.</p>

RESUMO

Based on the NSP4 sequence of bovine rotavirus (BRV), the shRNA was designed and synthesized, and a shRNA recombinant lenti-virus vector RNAi-H1-89 was constructed. The recombinant RNAi-H1-89 Lenti-virus was packaged by transfecting the 293T cell with the recombinant vector RNAi-H1-89 and two helper plasmids using lipofectamine, and then used to infect MA104 cells. The MA104 cells were further infected with BRV strain G6 24h post-infection, with the LacZ shRNA recombinant lenti-virus as control. Thirty-six hours later, the CPE of the infected cells was observed under microscope, shRNA of NSP4 gene inhibited CPE in MA104 cell; the shRNA against NSP4 gene also inhibited NSP4 gene expression by RT-PCR, The virus titer in the cell culture supernatant was significant lower compared with the control group. The above results showed that RNAi-H1-89 against NSP4 gene could specifically silence NSP4 gene expression, and inhibit the proliferation of BRV.

RESUMO

Interferon a gene was cloned from genomic DNA of Chinese Luxi yellow cattle by PCR, and the PCR product was inserted into vector pET32a( + ) to make a recombinant plasmid pET32a( + )/BoIFN-alpha. The expression of BoIFN-alpha in Escherichia coli was induced by addition of IPTG. Sequence analysis showed that the Chinese Luxi yellow cattle IFN-alpha gene is composed of 498 nucleotides, encoding a mature polypeptide of 166 amino acids. Compared with other BoIFN-alpha subtypes, it shares the highest identity of 97.6% to the C-subtype. SDS-PAGE results showed that recombinant proteins were expressed in inclusion bodies in Escherichia coli with molecular weight of 40 kD and the recombinant proteins accounted for 26.7% of the whole proteins.The expressed product was purified by affinity chromatography with immobilized nickel chelating NTA (Ni-NTA) and its antiviral activities were tested on MDBK/VSV cell system. Its antiviral activities were 5 x 10(5) u/mg on MDBK/VSV cell system. The results showed that the expression plasmid was successfully constructed and BoIFN-alpha C2 protein was expressed in Escherichia coli. Moreover the purification had good effects on antiviral activities.
