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.

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.

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.

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 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

Objective To evaluate the relationship between plasma cystatin C concentration (PcyC) and coronary artery diseases (CAD). Method A total of 126 subjects with CAD evidenced by coronary angiography admitted from April 2007 to March 2009 were divided into three groups: stable angina pectoris (SAPs, n = 34),unstable angina pectoris (UAPs, n = 56) and acute myocardial infarction (AMIs, n = 36), according to the diag-nostic criteria of CAD set by WHO. Another 34 subjects without CAD were taken as controls. There were no statis-tical differences in demographics among four groups. Serum lipids profile, uric acid (UA), PcyC and high-sensi-tive C-reactive protein (hs-CRP) were determined. And in the meantime, all patients were followed up for six months and adverse cardiovascular events were recorded. Comparisons were made between groups with a number of independent-sample t -tests. Data were processed with analysis of variance to test the differences in means among four groups, and the means were compared with chi-square test. Statistical significance was established at a P val-ue of less than 0.05. Results Cystatin C levels were significantly higher in UAPs than that in SAPs and in controls (P < 0.05), but were much lower than that in AMIs (P < 0.05). And much higher concentration of hs-CRP was found in UAPs (P < 0.05) and in AMIs (P < 0.01). Cystatin C was positively and significantly corre-lated with age, hs-CRP, WBC, creatinine and UA (r > 0, P < 0.05), whereas a significantly negative correla-tion with high-density lipoprotein cholesterol was found (r = - 0.227, P < 0.05). These coefficients were obvi-ously high for creatinine (r = + 0. 612), and WBC (r = + 0.459). During the period of six-month follow-up, 26 patients with adverse cardiovascular events were found, and had significantly higher cystatin C levels than 22 con-trols at admission (P < 0.01). Conclusions Cystatin C plays a pivotal role in the course of CAD, and the PcyC is a strong predictor for the risk of cardiovascular events.
