OBJECTIVETo investigate the relationship between degree of abnormal deeper lateral femoral notch between anterior cruciate ligament tear.

METHODSThe radiograph and MRI image material of 16 patients with anterior cruciate ligament injury from January 2013 to November 2013 were reviewed including 14 males and 2 females with an average age of 28.3 years old ranging from 18 to 52 years. Eleven cases was on right side and 5 on left. Survey tool of PASC imaging system was used to measure the depth of lateral femoral notch in patients with abnormal indicated by lateral X-ray view or sagittal view of MRI in knee joint,while clinical data,physical examination,image material in arthroscopy of these patients were retrospective researched.

RESULTSFour patients had an abnormal lateral femoral notch with the depth of 2 mm on lateral X-ray and sagittal MRI, while positive anterior drawer sign and Lachman test as well as anterior cruciate ligament tears on MRI, and completed tears were comfirmed on the operation of arthroscopy. Two patients without abnomal lateral femoral notch on lateral view of X-ray while with the depth of 1 mm on sagittal view of MRI were also coupled with positive anterior drawer sign and Lachman test as well as anterior cruciate ligament tears on MRI, and one of them were comfirmed completed anterior cruciate ligament tears on the arthroscopy operation and completed tear could not comfirmed on another one because of disagreed with arthroscopy operation.

CONCLUSIONThere appears to be an association between abnormal lateral femoral notch on lateral view of knee with anterior cruciate ligament tears. An abnormal deeper lateral femoral notch is an indirect evidence for anterior cruciate ligament tears.

Objective To explore the clinical characteristics,management and pregnancy outcome in patients with ovarian tumor and ovarian tumor like condition complicated with pregnancy.Methods The clinical data of 248 patients with ovarian tumor and ovarian tumor like condition eomplicated with pregnancy who treated,operated and pathology conducted from January 2003 to December 2009 was analyzed retrospectively.Results Among of 248 patients,8 patients were found by pelrioscopy,184 patients were found by sonography.The rate of ovarian tumor and ovarian tumor like condition during pregnancy was 0.49％ (248/50 652),about 52.82％(131/248)were diagnosed as benign tumor,most of them were ovarian mature teratoma(22.18％,55/248).About 45.56％(113/248)were diagnosed as ovarian tumor like condition,most of them were ovarian chocolatecyst(23.79％,59/248).Four patients(1.61％,4/248)were ovarian malignant tumor.Two hundred and sixteen received operation,term birth was in 164 patients,premature birth was in 19 patients,miscarriage was in 33 patients.Conclusions Pelvioscopy and sonogaraphy are principally important in the diagnosis and detection of ovarian tumor during pregnancy.Pregnancy complicated with ovarian tumor or ovarian tumor like condition should be treated by tumor resection.Suitable surgery intervention during second trimester is safe.

In order to investigate whether cytokine-induced killer (CIK) cells can induce apoptosis of bcr-abl(+) K562 cells, apoptosis of K562 cells and CEM cells induced by CIK cells, etoposide or camptothecin was detected with flow cytometry DNA assay. RT-PCR showed that K562 cells expressed the bcr-abl fusion gene, K 562 cells, K562 cells/etoposide or K562 cells/camptothecin groups showed no sub-G(1) peak. K562 cells/CIK cells group showed sub-G(1) peak (38.1%). CEM cells showed no sub-G(1) peak. CEM cells/camptothecin or CEM cells/etoposide groups showed sub-G(1) peak (23.5% or 32.3% respectively). CEM cells/CIK cells group showed sub-G(1) peak (45.4%). Etoposide or camptothecin did not induce apoptosis of K562 cells. CIK cells induce apoptosis of K562 cells. Bcr-abl fusion gene prevented apoptosis induced by etoposide or camptothecin, but did not prevent apoptosis induced by CIK cells. This property may support the observed adoptive immunologic effect of allogeneic bone marrow transplantation and donor lymphocyte transfusions of CML case relapsing after allogeneic bone marrow transplantation.

OBJECTIVETo evaluate the randomized controlled trials on preventing and treating restenosis after percutaneous coronary intervention (PCI) with Chinese medicine adopting the principle of evidence-based medicine (EBM).

METHODSPertinent literatures were retrieved roundly, and scored depending on Jadad Quality Scale. Meta-analysis was applied on the total effect of outcomes reported using RevMan 4. 2 software. Moreover, the sensitivity was analyzed, the publication bias was identified with funnel-plot and the adverse reaction of medicine was reported.

RESULTSAmong the 17 literatures met the inclusion criteria, only two double-blinded trials were appraised as high quality. The analysis on the recurrence rates of restenosis post-PCI and angina pectoris in patients treated with Chinese medicine illustrated that the rates in the treatment group were all lower than those in the control group with statistical significance (P < 0.01). Sensitivity analysis revealed a relatively stable result of the evaluation. Funnel-plot displayed an asymmetrical figure, indicating the possible existence of publication bias.

CONCLUSIONTCM has definite therapeutic effect on preventing and treating restenosis after PCI and reducing the recurrence rate of angina pectoris in patients.

Objective:To evaluate the clinical outcome of botulinum A toxin(BTX-A)injection into external sphincter combined with oral baclofen in treatment of detrusor-external sphincter dyssynergia(DESD)after spinal cord injury(SCI). Methods:A total of 38 urodynamic examination-confirmed DESD patients,male 31 and female 7,with an average age of (36.5?17.8)years old,were included in this study.200 U of BTX-A toxin was dissolved in 8 ml of normal saline and the solution was injected at 8 different sites(1 ml per site)of the external sphincter via a 5F flexible cystoscopic needle.On the second day,9 patients(BTX-A+baclofen group)were randomly selected for baclofen oral administration,3/d for 3 months; the other 26 patients were taken as control.Urodynamic examination was repeated in all patients 4 weeks later;the voiding diary and urodynamic outcomes were compared before and after treatment.The adverse and toxic effects were observed in the patients who were followed up for 2-9 months.Results:One month after treatment the voiding and storing functions of bladder were improved to different degrees,with the mean maximum uroflow rate(Qmax),the mean urine volume,the mean maximal cystometric capacity and the bladder compliance increased significantly and the mean postvoid residual urine volume and the mean maximal voiding pressure decreased significantly(all P

OBJECTIVESTo observe olfactory ensheathing glia (OEG) survival and repair in vivo for spinal cord injury after OEG transplantation.

METHODSThe OEG was cultured with the olfactory bulb of Wistar neonate rats. The spinal cords contusion was made in group A, B, and C with the New York University impactor, then complete transection was performed in the contusion area in group A. OEG labeled by Hoechst was transplanted in group A and B. In group C, DMEM were injected. In group D, laminectomies were done without cord contusion and transection. The functional recovery of the spinal cord injury [Basso, Beattie, Bresnahan (BBB) Locomotor Rating Scale scores] and changes of body weight were observed. The tissue sections were done 24 weeks postoperatively. HE staining, neurofibril (NF) immunohistochemical staining, and silver staining were performed respectively to observe the pathologic changes and axon regeneration. The survival of OEG labeled by Hoechst was observed under the fluorescence microscope.

RESULTSLocomotive behaviour improved 4 weeks postoperatively. The BBB locomotion scores of group A and B were significantly higher than that of group C in all periods (from 4 weeks to 24 weeks) (P < 0.01). Sixteen weeks after operation, the BBB locomotion scores became stable and showed no change. HE staining showed that the area of spinal cord injury was disorder and the number of nerve cell was more in group A and B. In group C, there was the obvious cavum and few wring nerve fiber in the area of spinal cord injury. The nerve fibers innervated to the injuried area in group A and B were more than that of group C, but less than that of group D. A great number of OEG labeled by Hoechst were observed around spinal injuried area under fluorescence microscope. After operation, the body weight reduced in every group. The body weight of group D had recovered after 2 weeks and gradully increased. After 4 weeks, the body weight in group A, B, and C decreased to the minimum and were significantly less than that of group D (P < 0.01). After this, body weight in group A and B increased and was significantly more than that of group C (P < 0.05).

CONCLUSIONSOEG transplantation can promote the axons regeneration and the recovery of locomotion function in experimental spinal cord injuries.

OBJECTIVETo explore the strategies which reduce the amount of xenoantigen Galalpha1,3Gal.

METHODSHuman alpha-galactosidase gene and alpha1,2-fucosyltransferase gene were transferred into cultured porcine vascular endothelial cells PEDSV.15 and human alpha-galactosidase transgenic mice were produced. The Galalpha1,3Gal on the cell surface and susceptibility of cells to human antibody-mediated lysis were analyzed.

RESULTSHuman alpha-galactosidase gene alone reduced 78% of Galalpha1,3Gal on PEDSV.15 cell surface while human alpha-galactosidase combined with alpha1,2-fucosyltransferase genes removed Galalpha1,3Gal completely. Decrease of Galalpha1,3Gal could reduce susceptibility of cells to human antibody-mediated lysis, especially during co-expression of alpha-galactosidase gene and alpha1,2-fucosyltransferase gene. RT-PCR indicated positive human alpha-galactosidase gene expression in all organs of positive human alpha-galactosidase transgenic F1 mice including heart, liver, kidney, lung, and spleen, the amount of Galalpha1,3Gal antigens on which was reduced largely. 58% of spleen cells from F1 mice were destroyed by complement-mediated lysis compared with 24% of those from normal mice.

CONCLUSIONSHuman alpha-galactosidase gene and alpha1,2-fucosyltransferase gene effectively reduce the expression of Galalpha1,3Gal antigens on endothelial cell surface and confers resistance to human serum-mediated cytolysis. The expression of human alpha-galactosidase in mice can also eliminate the Galalpha1,3Gal antigens in most tissues and decrease the susceptibility of spleen cells to human serum-mediated cytolysis.

OBJECTIVECombine olfactory ensheathing glia (OEG) implantation with ex vivo non-viral vector-based neurotrophin-3 (NT-3) gene therapy in attempting to enhance regeneration after thoracic spinal cord injury (SCI).

METHODSPrimary OEG were transfected with cationic liposome-mediated recombinant plasmid pcDNA3.1(+)-NT3 and subsequently implanted into adult Wistar rats directly after the thoracic spinal cord (T9) contusion by the New York University impactor. The animals in 3 different groups received 4x10(5) OEG transfected with pcDNA3.1(+)-NT3 or pcDNA3.1(+) plasmids, or the OEGs without any plasmid transfection, respectively; the fourth group was untreated group, in which no OEG was implanted.

RESULTSNT-3 production was seen increased both ex vivo and in vivo in pcDNA3.1(+)-NT3 transfected OEGs. Three months after implantation of NT-3-transfected OEGs, behavioral analysis revealed that the hindlimb function of SCI rats was improved. All spinal cords were filled with regenerated neurofilament-positive axons. Retrograde tracing revealed enhanced regenerative axonal sprouting.

CONCLUSIONNon-viral vector-mediated genetic engineering of OEG was safe and more effective in producing NT-3 and promoting axonal outgrowth followed by enhancing SCI recovery in rats.
