OBJECTIVETo explore effective approaches of treating elderly patients with distal tibiofibular fractures.
METHODSFrom August 2008 to October 2012,175 elderly patients with distal tibiofibular fractures were treated with locking compression plate (LCP) through anterior tibial. There were 112 males and 63 females with an average of 71.3 (ranged 60 to 83) years old. Of them,89 cases were treated by anterior tibial tension reduced incision with LCP,including 62 males and 27 females with a mean age of (71.8 +/- 6.4) years old. Eighty-six patients were treated by distal tibial incision with LCP,including 58 males and 28 females with a mean age of (70.3 +/- 6.7) years old. Swelling time, operation time, intraoperative blood loss, hospital stay, healing time, complications and AOFAS scores were compared between two groups after operation.
RESULTSSwelling time in anterior tension reduced incision with LCP and distal tibial incision with LCP was (5.6 +/- 1.3) and (9.7 +/- 2.1) days, healing time was (4.2 +/- 1.4) and (5.4 +/- 1.9) months,and complications were found 3 in tension reduced incision and 10 in distak tibial incision respectively;and all data shown statistically significant differences between two groups (P < 0.05). At 12 months after operation,AOFAS score was 89.0 +/- 9.7, 87.9 +/- 9.4; and there was no statistically significant difference between two groups (P > 0.05).
CONCLUSIONTension reduced incision through anterior tibial combined with locking compression plate fixation in treating elderly patients with distal tibiofibular fractures can provide good clinical effects with quick fracture healing and low complications.

AlM:To evaluate the expression of transcriptional factor lslet-1 in retina in experimental retinal neovascularization induced by oxygen.
METHODS: The murine retinal neovascularization were induced by hyperoxia exposure. The morphological observation of retinal neovascularization was performed using angiography by fluorescein dextran injection under the fluorescence microscope, and the new blood vessels were quantified after 5d in room air (17-day-old) by counting the vascular epithelial cell nuclei protruding into viteous cavity using HE stain. Realtime PCR and Western blot were used to examine retinal lslet-1 level in postnatal 7,12, 14,17 and 26d respectively.
RESULTS: A lots of new blood vessels were demonstrated in the mouse retina in hyperoxic group by fluorescein angiography and histological method. Moreover, no significant difference was found in retinal lslet-1 level in postnatal 7d between hyperoxic group and control group, but was significantly higher in postnatal 12, 14 and 17d mice compared with control mice. However, mice at postnatal 26d, expression of lslet-1 in retina decreased to normal level.
CONCLUSlON: ln processing mouse model of retinal neovascularization, sustained hypoxia retinal tissue induce retinal neovascularization by increas the expression of transcription factor lslet-1.

Objective To investigate the anatomic feature and exposing methods of recurrent laryngeal nerve(RLN) in thyroid surgery. Methods The data of 327 cases of thyroid tumor were analyzed retrospectively. The anatomic feature, injury and prevention of RLN were discussed. Of all the cases, 293 RLNs (242 cases) were anatomically exposed. Results The temporary injury rates of RLN was 1.65% (4/242) in the exposed group and 8.23% (7/85) in the unexposed group with a persistent injury rate of 2.35%(2/85). The differences of temporary injury rates and persistent injury rates between the two groups were statistically significant (P<0.05). 67.23% (197/293) of the RLNs had two branches before entering larynx, 61.09%(179/293) of RLNs were posterior to the inferior thyroid artery and 31.39% (92/293) anterior to the inferior thyroid artery, 4.09% (12/293) passed through the bifurcation of inferior thyroid artery, and 4. 13% (10/293) were not related to the inferior thyroid artery. The incidence of non-recurrent laryngeal nerve (inferior laryngeal nerve) was 0.68% (2/293). Conclusions The anatomic relation of RLN is relatively complicated along its journey. The injury of RLN could be reduced with designed exposal during the thyroid surgery.

2', 3', 5'-Tri-O-acetyl-N6-(3-hydroxylaniline)adenosine (WS070117) is a derivative compound of natural product cordycepin. It has significant lipids regulating activity and low toxicity which has been proved by in vitro and in vivo experiments. In this study, 1H NMR-based metabolomics was used to investigate the dose-related effects of WS070117 on hyperlipidemia of high-fat-fed hamsters. The hyperlipidemic hamsters were administrated with six different doses of WS070117, including 3, 12, 50, 100, 200 and 400 mg x kg(-1) x d(-1). 1H NMR spectra of hamster serum were visually and statistically analyzed using two multivariate analyses: principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). As a result, WS070117-treated groups showed dose-related regulation of metabolites associated with lipid metabolism, choline metabolism and glucose metabolism. The dose of 3 mg x kg(-1) x d(-1) of WS070117 only exhibited a little lipids regulating activity. However, the doses of 12 and 50 mg x kg(-1) x d(-1) of WS070117 both regulated the contents of metabolites to reverse significantly toward normal levels. When the dose of WS070117 reached 100 mg x kg(-1) x d(-1), it was more effective than positive control drugs. The work suggested that NMR-based metabolomics might be a valuable approach to evaluate dose-related effects of lipids regulating compounds.

BACKGROUND:Adenovirus, expressing within a limited period, can limit the expression time and amount of target genes that is not conducive to ongoing experiments. Here, we select adenovirus as vectors for genetic recombination with tumor necrosis factor (TNF)-related apoptosis-inducing ligand (Trail) gene fragment.
OBJECTIVE:To explore the construction of recombinant lentiviral vector carrying Trail in rats
METHODS:The Trail gene was obtained:according to GenBank in rat Trail gene sequence (NM_145681.1), we designed the gene specific primers of Trail-Age I-F and Trail-AgeI-R, and used AgeI as enzyme cutting site. PCR was applied to amplify Trail gene from rat cDNA Library and construct recombinant plasmids after cutting Trail gene to be cloned into expression vector GV218 by AgeI. Recombinant plasmids were transfected into 293T cells by Lipofeetamine2000 encapsulated recombinant plasmid and auxiliary packaging carrier. The Trail protein of lentiviral plasmids was expressed. Fol owing virus col ection, we identified virus titer and extracted protein from cells to detect Trail expression by western blot assay.
RESULTS AND CONCLUSION:Screened positive Escherichia coli DH5a competent cells were sequenced with 861 bp, which was consistent with Trail nucleotide sequence in GenBank. After transfection 2 days, virus liquid was col ected and confirmed as recombinant plasmid including Trail gene by PCR and Trail proteins expressed in 293T cells by western blot assay. Hole dilution method and real-time fluorescent quantitative PCR determination showed that the virus titer was 2×109 TU/mL. In this study, recombinant lentiviral vector carrying Trail is successful y constructed by homologous recombination in Escherichia coli.

This study deals with colony expansion characteristics, biomass increment and Na accumulation in mycelia of three ectomycorrhizal fungi ( Boletus edulis, Xerocomus chrysenteron and Gomphidius viscidus ) under treatment of Na2SO4 and NaCl. The experimental results showed that no impact was observed from Na2SO4 and NaCl treatments on the growth mode of the mycelia, but the biomass increment of X. chrysenteron and G. viscidus was significantly restrained under 0.1 mol/L Nacl. Under the treatment of Na2SO4, biomass increment of X. chrysenteron is significantly higher than the control, but the biomass of G. viscidus is lower than that of the control, and no significant impact was measured on growth of B. edulis under both treatments of Na2 SO4 and NaCl. The experiment also indicated that Na accumulation in mycelia varied significantly among the three tested strains, highest Na accumulation was measured in X. chrysenteron under treatment of NaCl, while under the treatment of Na2SO4 , accumulation of Na in B. edulis is much higher than the other two strains.
