Objective To explore the influence and potential protective effects of non-specific panMetrix Metalloproteinases(MMPs) inhibitor Doxycycline on hyperoxic lung injury and lung development in neonatal rats.Methods Neonatal SD rats were divided into 4 groups randomly within 12 hours after birth:air with normal saline(AN),air with doxycycline(AD),hyperoxia with normal saline(ON),and hyperoxia with doxycycline group(OD).Hyperoxia groups(ON and OD) were exposed to ≥90% O2.Doxycycline 20 mg/kg or equal volume of 0.9% saline(Doxycycline concentration 2 mg/ml) was administered by gastric gavage,twice daily from day 1 to experimental day,but it didn't exceed 14 days.Stereological study was carried out at day 1,3,7,14 and 21 after birth.Results Enlarged mean alveolar area was noted both in hyperoxia and Doxycycline groups.OD group had larger star volume than ON group on day 14.Except ON group,all other groups had increased alveolar septum and the condition was worsened by hyperoxia with Doxycycline.The percentage of collagen in lung parenchymal tissue in ON group increased persistently.This increasing trend was stopped in OD group on day 14,and collagen percentage had no significantly difference between OD and AN groups on day 14 and 21.Conclusion Both hyperoxia and Doxycycline influence neonatal lung development,percentage of coUgen in lung parenchymai can be reduced by Doxycycline in hyperoxic lung injury.

Objective To determine the incidence of clinically common acute avulsions of the popliteus tendon (PT) and the lateral collateral ligament (LCL) of the femur (peel-off lesion) in knees with multiple injured ligaments.Methods A retrospective review of 48 acute grade 3 posterolateral corner (PLC) knee surgeries was conducted.All office evaluations were reviewed to determine the demographic data,tear description,preoperative MRI examination,physical examination under anesthesia,intraoperative arthroscopic findings and surgical techniques.Results In total,19 patients were surgically verified as having femoral peel-off lesions as a portion of a series of multiple pathologic findings.Tear patterns were typically categorized into 3 patterns:isolated PT tear (pattern 1,4 patients),combined PT and LCL tears (pattern 2,8 patients) and complex tears (associated intrasubstance and/or fibular-based injuries,pattern 3,7 patients).Seventeen of the 19 patients underwent preoperative MRI examination,which demonstrated conclusive signs of femoral insertion separation and discontinuity in 13 patients (76%) and inconclusive signs of femoral insertion separation.Examination under anesthesia (EUA) revealed that for the 4 patients with pattern 1 injuries,the tibial external rotation increases were all greater than 10°.For the 15 patients with pattern 2 and 3 injuries,the yarus instability was as follows:grade 3 in 8 patients,grade 2 in 2,grade 1 in 1,and negative in 4.External rotation increases were greater than 10° in 12 patients and less than 10° in 3.Seventeen of the 19 patients were inspected with an arthroscope prior to PLC surgery:of these patients,94% had acute avulsion findings and positive lateral gutter drive-through sign;8 patients were repaired with recess or reattachment procedures;6 patients were primarily reconstructed;4 patients were treated with combined repair and reconstruction;and 1 patient was left untreated for secondary reconstruction due to priority repair for concurrent patellar tendon rupture.Conclusion For adequate clinical identification,we recommend a comprehensive diagnostic protocol,including MRI,physical examination and arthroscopic inspection,to avoid underdiagnosis of the lesion in multiple-ligament injured knees.The lateral gutter arthroscopic evaluation is particularly sensitive for detecting the lesion.

Objective To evaluate the effect of training for therapists based on Kirkpatrick's Four-level Model. Methods Totally 39 ther-apists who completed 2014 Beijing Clinical Shortage of Manpower Training Programs (Therapist) were investigated with Kirkpatrick's Four-level Model, named reaction, learning, behavior and results. Results For reaction level, the total satisfaction was high, but different with the degree of education, especially in the items of Participate in Training, Type of Cases, Organizing on Practice Training, Organizing Case Discussions and Get A Lot of Benefits from the Training (F>4.59, P<0.05). For learning level, the test scores were significantly differ-ent before and after the training (t>9.53, P<0.001). For behavior level, the self-reports of the therapists, and the reports from their depart-ment directors and colleagues all agreed that their ability improved after training (t>4.44, P<0.001). For results level, eleven therapists passed the rehabilitation therapist test, two therapists participated in some researches, and one published an article. Conclusion The thera-pists satisfied in the training, that may improve the ability of therapists to contribute to their organization.

Objective To investigate the changes of cardiotrophin-1(CT-1) expression in rats with pressure overload-induced cardiac hypertrophy,and the effects of benazepril on this expression and the concerned cardiac hypertrophy.Methods The model of pressure overload was established by constriction of abdominal aorta and divided randomly into hypertrophied group(LVH,n=7) and benazepril intervention group(Ben,n=7,benazepril 1mg?kg~(-1)?d~(-1) orally)2 weeks later.A sham-operation group(Sham,n=7) served as control.Blood pressure and left ventricular mass index(LVMI) were investigated after 3 weeks' treatment.AngⅡ level in myocardium was measured by radioimmunoassay.The mRNA level of CT-1 was examined by RT-PCR.Results Compared with the sham group, blood pressure and LVMI in LVH group were increased significantly(P

Aim To study the mutidrugresistance mechanism of tumor cell by comparing the binding pro-tein with Adriamycin(ADM)in the MCF-7/Wild cell and MCF-7/ADM resistance cell.Methods The biotin-ADM compound was synthesized with the esterification-dehydration method,purified with HPLC and analyzed with mass spectrograph.The binding proteins against Adriamycin from MCF-7/ADM or MCF-7/Wild cell whose resistance index is above 200 were obtained respectively by the affinity screening magnetism bead method with biotin-ADM compound as a specific ligand.Some binding proteins with Adriamycin were identified with the MALDI-TOF-MS after isolating them with SDS-PAGE.Cell motor ability was compared in the migration experiment.Results The variability of biotin-ADM and ADM was negligible,while that IC50 of the two compounds to MCF-7/Wild was 0.796 ?mol?L-1 and 0.547 ?mol?L-1 respectively.The 20 types binding proteins with ADM were found from MCF-7/Wild cell,and 17 types binding proteins from MCF-7/ADM resistance cell.There was one protein band difference from the two cells on SDS-PAGE with silver staining.The same binding proteins on the two cells that identified with MALDI-TOF-MS were myosin,beta-actin,alpha-actin,keratin.MCF-7/W and MCF-7/ADM both migrated after being cultivated 72 h,with a faster migration of MCF-7/ADM.Conclusion There are different binding protein with ADM on the MCF-7/Wild cell and MCF-7/ADM resistance cell.The same binding protein with ADM on the two cells belongs to the cystoskeleton protein.The binding of the ADM with the cell cystoskeleton protein has some effect to the migration of the MCF-7/ADM.
