BACKGROUND:Current clinical studies seldom concern biomechanical properties of lateral plate combined with medial percutaneous lag screw. Moreover, effects of clinical application to distal tibial fractures are not investigated. OBJECTIVE:To explore biomechanical properties of lateral plate combined with medial percutaneous lag screw, and to analyze the repair effect on distal tibial fractures. METHODS:Six adult antiseptic tibia specimens were studied. Bone saw was used to make a bone defect in 1 cm length, which was fixed with lateral plate and lateral plate combined with medial percutaneous lag screw. Three point bending test, axial compression test and rotation test were performed. Clinical data of twenty cases of distal tibial fracture patients from the Department of Orthopedics of Hebei Medical University were analyzed and randomly divided into lateral plate groupand lateral plate combined with medial percutaneous lag screw group (n=10). Clinical repair effects were compared between the two groups. RESULTS AND CONCLUSION:(1) Biomechanical indexes of cadaver specimens: no significant difference in torsional strength was determined between the two groups (P> 0.05). Bending stress and axial displacement were significantly lower in the lateral plate combined with medial percutaneous lag screw group than in the lateral plate group (P< 0.05). (2) Repair surgery related indicators: operation time, intraoperative blood loss, length of stay and fracture healing time were significantly less in the lateral plate combined with medial percutaneous lag screw group than in the lateral plate group (P< 0.05). (3) Repair effects: There were nine cases of fracture healing in the lateral plate combined with medial percutaneous lag screw group 3 months after treatment. The total effective rate was significantly higher in the lateral plate combined with medial percutaneous lag screwgroup (90%) than in the lateral plate group (70%) (P<0.05). (4) These findings indicate that lateral plate combined with medial percutaneous lag screw has a unique advantage in resisting axial compression, torsion and bending. Its application to distal tibial fractures obtains ideal effects, can improve the clinical efficacy and stability.

In this article,we reviewed the clinical characteristics of refractory FGIDs accompanying with psychological disorders and the progress in research on their diagnosis and treatment for improving the understanding and formularizing the management of this disease.

BACKGROUND:It is likely to find that ABCE1 plays an important part in the occurrence and progression of cancers through in-depth study. OBJECTIVE:To investigate the effects of ABCE1 silencing on the proliferation and sensitivity toβ-eiemene of ovarian cancer stem cel s via electrotransfection. METHODS:siRNA sequence of ABCE1 was designed and synthesized, and then was electrotransfection into ovarian cancer stem cel s. Subsequently, expressions of ABCE1 mRNA and protein in ovarian cancer stem cel s after ABCE1 silencing were detected by RT-PCR and western blot assay;the cel cycle was detected using flow cytometry;the sensitivity of ovarian cancer stem cel s toβ-eiemene after ABCE1 silencing was analyzed by MTT assay and colony-formation assay. RESULTS AND CONCLUSION:After ABCE1 silencing, expressions of ABCE1 mRNA and protein in ovarian cancer stem cel s were significantly reduced. And the cel cycle was arrested in G0/G1 phase, and the number of cel s in S phase significantly decreased. Furthermore, the sensitivity of ovarian cancer stem cel s toβ-eiemene after ABCE1 silencing was significantly enhanced. In conclusion, ABCE1 silencing cannot only significantly inhibit the proliferation of ovarian cancer stem cel s, but also enhance the sensitivity of cancer stem cel s toβ-eiemene.

Objective To confirm the risk factors of poor prognosis in patients with severe acute epiglottitis by comparing symptoms and results of laboratory tests.Methods A total of 698 patients with acute epiglottitis from outpatient and emergency room from 1995 to 2014 were retrospectively studied.These patients were divided into severe or mild group as per the means of treatment of airway including invasive (n =115)and non-invasive (n =583).The past history,general conditions and laboratory tests were compared between the two groups by chi-square or t test;the spearman correlation between the degree of dyspnea and epiglottis edema was analyzed,and the risk factors of poor prognosis were detected by logistic regression.Results The ratio of male to female was 1.366/1.There was a high prevalence of sever acute epiglottitis in spring,winter and at night, respectively.More smokers were found in the severe group compared with the mild group (χ2 =41.957,P <0.01).Severe dyspnea and low PaO2 (r =0.573,P <0.01),but not the poor grading of epiglottis edema evaluated by pharyngo-fiberoscope (r =-0.024,P =0.525),were correlated with poor prognosis.Male (OR =1.84,95%CI:1.41 -3.22,P =0.001),an attack at night (OR =2.61,95%CI:1.98 -3.16),P =0.07), smoker (OR =1.63,95%CI:1.05 -3.39,P =0.04)and low PaO2 (OR =2.97,95%CI:1.58 -4.49,P =0.02)were independent risk factors for a poor prognosis.Conclusions Male,an attack at night,smoker and low PaO2 were independent risk factors for a poor prognosis of acute epiglottitis.A critical care should be given to patients with those risk factors,even their epiglottis edema was not very serious.
