OBJECTIVETo investigate the feasibility and effectiveness of modified Stoppa approach in treatment of bilateral pubic fractures of pelvic.

METHODSThe therapeutic effects of 16 patients with bilateral pubic fractures treated through the modified Stoppa approach from January 2010 to January 2014 were summarized and analyzed, involved 11 males and 5 females with an average age of 40.5 years old ranging from 17 to 59 years. According to Tile classification, there were 8 patients with type A, 6 with type B and 2 with type C. For 16 pelvic fractures, the modified Stoppa approach was used exclusively 11 cases, in combination with the iliac fossa approach in 4 cases, and in combination with the posterior approach in 1 case. The operation incision length, operation time , intra-operative blood loss and postoperative complications were observed. The fracture reduction and post-operative function were assessed by Matta criteria and Majeed system respectively.

RESULTSThe incision length of the modified Stoppa approach ranged from 8 to 10 cm (averaged in 9 cm). The operation time ranged from 75 to 135 minutes (averaged in 95 minutes). The intra-operative blood loss ranged from 400 to 900 ml (averaged in 600 ml). Sixteen patients were followed up from 7 to 18 months (averaged in 12.5 months). The fractures were all healed, the fracture healing time was 2.7 to 5 months (means 3.1 months). There were no infections, ectopic ossification, screw loosening, plate breakage and lateral ventral syndrome. According to Matta criteria for pubic fracture reduction, the result was excellent in 9 cases, good in 6, fair in 1. The Majeed function scores at 6 months after operation was 85.32±8.50; the result was excellent in 8 cases, good in 6 cases, fair in 2 cases.

CONCLUSIONThe modified Stoppa approach has characteristics of convenience and directness of incisions, clear operation field, easy reduction, few complications and fast recovery , it is an ideal choice in surgical treatment of bilateral pubic fractures.

OBJECTIVETo observe the changes in Aβ40, Aβ42 and ADDLs in brains of 3 month-old APPswe/PS1dE9 double transgenic mice after six-month intervention with curcumin, in order to discuss the neuroprotective effect of curcumin.

METHODAPPswe/PS1dE9dtg mice were randomly divided into the model group, the Rosiglitazone group (10 mg x kg(-1) x d(-1)) and curcumin high (400 mg x kg9-1) x d(-1)), medium (200 mg x kg(-1) x d(-1)) and low (100 mg x kg(-1) x d(-1)) dosage groups, with C57/BL6J mice of the same age and the same background in the normal control group. After 6 months, the immunohistochemical staining (IHC) and the Western blot method were used to observe the changes in positive cell of Aβ40, Aβ42 and ADDLs in hippocampal CA1 area, their distribution and protein expressions.

RESULTBoth of the immunohistochemical staining and the Western blot method showed more positive cell of Aβ40, Aβ42 and ADDLs in hippocampal CA1 area and higher protein expressions in the model group than the normal group (P < 0.01). IHC showed a lower result in the Rosiglitazone group than the model group (P < 0.05), while Western blot showed a much lower result (P < 0.01). The number of Aβ40, Aβ42 and ADDLs positive cells and the protein expressions decreased in the curcumin high group, the medium group showed a significant decrease (P < 0.01), and the low dose group also showed reductions in the protein expressions of Aβ40 and Aβ42.

CONCLUSIONThe six-month intervention with curcumin can significantly reduce the expressions of hippocampal Aβ40, Aβ42 and ADDLs in brains of APPswe/PS1dE9 double transgenic mice. Whether curcumin can impact Aβ cascade reaction by down-regulating expressions of Aβ40, Aβ42 and ADDLs and show the neuroprotective effect needs further studies.

70 bpm during scan),the proportion of segments that could not be assessed because of motion artifact were 0.1%(1/759),1.1%(7/649),2.5% (10/407),42.6%(103/242),and 75.5%(108/143),respectively.With conventional selective coronary angiography as the golden standard,the sensitivity,specificity,positive and negative prediction values to detect≥50% stenotic lesions in the assessable segments were 79.2%,96.0%,83.8%,and 94.6%,respectively.There was a significant correlation between the number of segments per patient not assessable because of motion artifact and heart rate during the scan(r=0.655,P=0.000).Conclusion MSCT is capable of achieving high accuracy for detection of coronary artery stenosis,and is a reliable technique to diagnose coronary artery disease.

Objective To obtain the recombinant corticotropin releasing hormone (CRH) protein with soluble, high purity protein through optimizing prokaryotic expression condition and purifying glutathione thiol transferase (GST)-CRH protein. Methods To detect the expression of soluble CRH protein through grope of the host strain GST-CRH temperature of induction expression, the host strain concentration (OD600), IPTG concentration and induction time, the purification of GST-CRH was performed by GST-CRH agarose gel. Western Blot assay was used for the expression identification of the target protein. Results The optimal conditions for the induction of CRH protein were determined: temperature of 30 ℃, IPTG induced concentration 0.1 mmol/L, bacteria density (OD600) 0.8, the induction time of 8 hours, purified GST-CRH>95% fusion protein was obtained. Conclusion The optimal expression conditions of GST-CRH are obtained, and the soluble protein of high purity GST-CRH is also obtained.

AIM:To observe the effect of arsenic trioxide (ATO) on bleomycin-induced pulmonary fibrosis in rats. METHODS:Pulmonary fibrosis was induced in Sprague-Dawley (SD) rats by intratracheal instillation of bleomycin (BLM). The rats in ATO treatment group,steroid treatment group and model group were intraperitoneally injected with ATO,dexamethasone or normal saline (NS),respectively,while the control rats received NS both intratracheally and intraperitoneally. The effects of ATO were evaluated by analyzing the median survival time,hydroxyproline level in the lung,semiquantitative grading of alveolitis and pulmonary fibrosis,and quantitative analysis of the collagen in lung tissue (Masson's trichrome staining). Apoptosis index (AI) of the lung was detected by using the terminal transferase dUTP-digoxygenin nick endlabeling (TUNEL) method. The results of immunohistochemical staining for some cytokines were quantitatively analyzed. RESULTS:ATO (1) prolonged the median survival time of rats with BLM-induced pulmonary fibrosis at some extent; (2) attenuated the alveolitis and pulmonary fibrosis,reduced hydroxyproline level and collagen deposition in the lung tissue; (3) increased the AI of lung tissue at a certain phase; and decreased the levels of transforming growth factor-?1(TGF-?1) and tissue inhibitor of metalloproteinase-1 (TIMP-1),increased the content of in-terferon-? (IFN-?),but did not influence the concentration of matrix metalloproteinase-9 (MMP-9) significantly. CONCLUSION:ATO might attenuate BLM-induced pulmonary fibrosis in rats via increasing the AI in the lung tissue.
