Objective To summarize our surgical experience in repair and functional reconstruction for compound defects of proximal phalanx and dorsal skin at multiple digits,Methods Six patients with multiple digital defects were treated in our department between June 1996 and March 2005.At the first stage,free iliac bone grafts were used to repair defects of proximal phalanges and temporary syndactyly between adjacent affected fingers was created through digital palmar skin sutures.The defects were covered with free flap transfer finally.Dorsalis pedis flaps were used in four patients,a lateral arm flap in one and a lateral thoracic flap in one respectively.At the second stage,a partial debulking procedure and division of syndaetyty followed three to six months later.Additional procedures were performed in three eases to reconstruct the digital extensor function through tendon transfer.The follow-ups ranged from six months to nine years.Results The flaps survived uneventfully in the six patients postoperatively.The dorsal aspects of reconstructed fingers demonstrated an aesthetically pleasing effect after the flap debulking procedures and division of syndactyly.Follow-up X-Ray examinations showed good lilac bone union and nearly normal structure of digital bone.The distal interphalangeal extension restored to normal in the three cases after extensor reconstruction.Conclusions Iliac bone graft to repair phalangeal defects and free flap transplantation to cover skin defects can be a good treatment for compound defects of proximal phalanx and dorsal skin at multiple digits.Secondary plastic procedure may greatly improve the appearance of a reconstructed digit,and extensor re- construction the function of distal interphalangeal extension too.

Objective: To investigate the antiatherosclerotic effect of Wujibaifeng Pills and its mechanism. Methods: Rat dyslipidema was induced by ovariectomy (OVX), the levels of serum lipids, superoxide dismutase (SOD) activities and malondialdehyde (MDA) were detected after 12 weeks with the treatment of wujibafeng pills. Results: Wujibaifeng Pills lowered serum oxidized-low density lipoprotein cholesterol (OX-LDL,P

To clarify the active components in Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma, main components were gradually knocked out from the capsules, the effects of knockout capsules on uterine contraction, TNF-α secretion, murine splenocytes (SPL) and hysteromyoma cells proliferation were evaluated, respectively. The inhibition of capsules on uterine contraction was weakened by gradient knockout of paeoniflorin, paeonol, and amygdalin. The suppression of capsulte on TNF-α secretion was reduced by gradient knockout of gallic acid, cinnamaldehyde, pentagalloylglucose, and pachyman. The promotion of SPL cells proliferation was reversed by gradient knockout of gallic acid, paeoniflorin, cinnamaldehyde, quercetin, and pachyman. The depression of capsules on hysteromyoma cells proliferation was attenuated by gradient knockout of paeoniflorin, paeonol, pentagalloylglucose, and albiflorin. In conclusion, the compounds mentioned-above could be the key active basis of Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma.

OBJECTIVETo construct and identify a lentiviral vector of RNA interference targeting human Notch-1 gene.

METHODSTo determine the Notch-1 gene sequences, three RNAi target sequences (shRNA1-3) were designed in accordance with the RNAi sequence design principles and cloned into the lentiviral vector pLenOR-THM by endonuclease BamH I restriction, EcoR I double digestion, and T4 DNA-ligase ligation. After the transformation into competent DH5alpha bacteria, the candidate clones were identified by Kpn I and EcoR I double digestion and DNA sequencing. The recombinant and three packaging plasmids were co-transfected into human embryonic kidney cell line 293T cells by lipofectamine to produce the lentiviral particles. The viral titer was determined. The 293T cells were infected by the lentiviral particles obtained, and transfection efficiency was assessed using a fluorescent microscope. The lentiviral vector particles were also transfected into ACC-M cells. The Notch-1 expression in the transfected cells was assayed by quantitative reverse transcription polymerase chain reaction (QRT-PCR) and Western blot analysis.

RESULTSThe lentiviral RNAi vector pLenOR-THM-Notchl for Notch-1 gene was constructed successfully. Strong green fluorescence was observed in the 293T cells under fluorescent microscope after co-transfection of the cells with the four plasmids of lentiviral vector. The virus in the supernatant reached a titer of 5.8 x 10(8) TU x mL(-1). The transfection efficiency of the collected virus exceeded 90% in 293T cells with 1 as a multiplicity of infection. The third lentiviral vector was found to significantly inhibit the Notch-1 expression at the mRNA and protein levels.

CONCLUSIONThe lentiviral RNAi vector of Notch-1 has been successfully constructed and identified.

Objective To investigate the injury and disruption of anterior sacroiliac ligament (ASIL) and sacrotuberous/sacrospinous ligament complex(STL/SSL),as well as the displacement of pubic symphysis (PS) and sacroiliac joint (SIJ),associated with anterior-posterior compression (APC) of Young-Burgess type Ⅱ.Methods Test models of APC of Young-Burgess type Ⅱ were created in 10 fresh human pelvic cadaveric specimens which were randomized into 2 equal groups (n =5).The fight hemipelvis in one group was fixed to a table (the limited group) while that in the other was not (the unlimited group).At the disruption point of ASIL during external rotation of the hemipelvis,displacement of PS,separation distance between the anterior parts of the sacroiliac joint,and injury and disruption of STL/SSL were recorded.When STL/SSL was gradually made to breakdown and fracture with continuous external rotation of the hemipelvis,bony changes and injuries to the posterior pelvic ligaments were observed and recorded.Results At the failure point of ASIL,the mean displacement of PS was 23.8 ± 2.8 mm and that of SIJ was 10.9 ± 4.4 mm,showing no significant difference between the limited and unlimited groups (P ＞ 0.05);the mean external rotation angle was 40.1°± 9.8° and the mean torsion was 646.7 ± 131.5 N,showing significant differences between the limited and unlimited groups (P ＜ 0.05).At the disruption point of ASIL,obvious injuries or disruption of STL/SSL were not observed in the unlimited group but observed in the limited group.With extreme external rotation,obvious disruption of STL/SSL was not found in the unlimited group but observed in the limited group.When ASIL and STL/SSL were all fractured,the mean displacement of PS was 41.8 mm and that of SIJ was 16.8 mm in the limited group.Conclusions Since APC injury can lead to 2 situations,limited or unlimited hemipelvis,external rotation injuries to the ligaments differ in the 2 different situations.When ASIL fails,the displacement of PS will fluctuate greatly.
