Objective To evaluate the relationship between recurrent intussusception and enlarged mesenteric lymph nodes (EMLNs) in children by ultrasound.Methods A total of 35 cases (a total of 75 relapse) with imaging features of recurrent intussusception were retrospectively analysed.The sequence,size,number,morphology and location of EMLNs were recorded.Results Twenty cases of EMLNs were found in 35 cases recurrent intussusception (57.1%,20/35).At least three EMLNs were found in and / or around the mesentery of intussusception.The imaging feature of recurrent intussusception was a " target" appearance on transverse scans and a "sleeve" sign on longitudinal scans .All the EMLNs were smooth and oval-shaped hypoechoic nodule.The largest longitudinal diameter of the EMLNs ranged between 7-20 mm ,the largest transverse diameter of the EMLNs ranged between 3-8 mm with the aspect ratio≥2.0.Conclusion The Enlarged mesenteric lymph node recurrence of intussusception in children is crucial factor.Ultrasound can not only accurately and timely diagnose and treat intussusception while scanning enlarged mesenteric lymph nodes,which can provide an important basis for reducing the recurrence of intussusception.

OBJECTIV:
e To find the correlation between real best corrected visual acuity (BCVA) and testing results of microperimetry and visual evoked potential (VEP) and to explore a new method in recording BCVA in macular disease.
METHODS:
Sixty-two patients with macular disease (macular disease group, 62 eyes) and eighteen healthy volunteers (control group, 36 eyes) had BCVA, microperimetry and VEP recorded.
RESULTS:
(1) By microperimetry, the values of retinal mean sensitivity and fixation percentage in macular disease group were lower than that in control group. The bicurve ellipse area in macular disease group was higher than that in control group. By VEP, P100 amplitude under 0.5 cpd and 2 cpd in macular disease group were significantly higher than that in control group and the latency was prolonged (P < 0.05). (2) In macular disease group, BCVA had significant positive correlation with retinal mean sensitivity, bicurve ellipse area, macular central 2 degrees and 4 degrees fixation percentage, respectively (P < 0.05). There was a significant correlation between retinal mean sensitivity and P100 amplitude (P < 0.05). (3) Multiple linear regression equation was y = 0.053 x1+0.008 x3+3.897 (y was BCVA, while x1 was retinal mean sensitivity and x3 was P100 amplitude under 2 cpd).
CONCLUSION
Combined use of microperimetry and VEP is useful in the assessment of BCVA in macular disease.

OBJECTIVETo explore whether the constructed vector of short haprin in vivo can induce human glioma cell line BT325 to produce RNAi duplexes and reverse the expression of MDR1 gene.
METHODSThree 62nt oligonucleotide fragments (shRNA) were constructed according to GenBank MDR1 sequence and were cloned to the retrovirus-delivered vectors. After transfected these vectors directly into the human malignant glioma BT325 cells by lipofectamine 2000 with enhanced green fluorescence protein (EGFP) co-transfecting, the MDR1 gene silence effects were detected by the changing level of mRNA and P-glycoprotein including real time PCR (RT-PCR), Northern blot and Western blot analysis. To assess the multidrug resistance against adriamycin (ADR) and VCR, cell proliferation assays were performed by cell counting kit-8.
RESULTSThe RNAi plasmid vectors were constructed successfully. RT-PCR showed MDR1 mRNA was significantly reduced (P < 0.05). Northern blot analysis showed that the gene silence became most intense at 48 hours after transfection. Western blot analysis demonstrated that P-gp expression was reduced at different time to 12.9%, 30.3% and 4.8%, respectively. The chemosensitivity assays indicated that the transfected cells showed an enhanced sensitivity to ADR and VCR. Based on the value of IC(50), BT325 cells had significantly increased sensitivity to the drugs.
CONCLUSIONThe sequence specific RNAi can inhibit MDR1 mRNA and P-gp expression in the glioma cell line. It may reverse multidrug resistance phenotype, therefore, may provide promising therapeutic modalities in the treatment of human glioma.

Objective To investigate effectiveness of meta-cognitive intervention on aged people with middle depression. Methods Geriatrist Depression Scale(GDS) and Hamilton's Depression Scale ( HAMD-17 ) were used to screen out 70 aged people with middle depression from 850 retired soldier cadres dwelling in cpla dalian sanitarium. They were randomly divided into study group( n = 35 ) and control group( n = 35 ). The experimental group received meta-cognitive intervening and general nursing care for 8 weeks, while the control group only received general nursing care for 8 weeks. HAMD-17, GDS, global assessment scale(GAS) and the Metacognitions Questionnaire(MCQ-30) were administered both at the start and the end of the 8th week. Results The total scores in HAMD and GDS were decreased significantly in study group ( HAMD: ( 1 1.54 ± 2.50 ) vs ( 13.06 ±2.82),t= -2.378, P=0. 020;GDS:(12.51 ±2.43) vs (16.06 ±2.48), t= -6. 031, P=0. 000;GAS:(77.71 ±3.03) vs (75.63 ± 3.24), t = 2. 785, P = 0. 007 ). At the end of 8th week, the MCQ total score was significantly decreased in study group (38.69 ± 4. 17,81.37 ± 5.98, t = 34. 652, P < 0. 01 ). Conclusion For aged people with middle depression,good effects are got by the meta-cognitive intervening technique and meta-cognitive intervening technique improve the meta-cognitive level of aged people with middle depressive mood.

AIM:To investigate the effect of phosphatidylinostiol 3-kinase ( PI3K) inhibitor GDC-0032 on cell viability, cell cycle and DNA damage in human glioma U 251 cells.METHODS:The cell viability was analyzed by MTT assay.The cell cycle distribution of U251 cells was examined by flow cytometry .The protein expression was examined by Western blot.The expression and localization of γ-H2AX were determined by laser-scanning confocal microscopy .RE-SULTS:GDC-0032 inhibited the cell viability in a dose-dependent manner .U251 cells showed G 1 phase arrest accompa-nied with upregulation of p 27 protein after exposure to GDC-0032, while the expression of cell division cycle protein 2 (Cdc2) was inhibited.GDC-0032 treatment increased the formation of γ-H2AX foci and histone H2AX phosphorylation in the U251 cells.In addition, GDC-0032 upregulated the phosphorylation levels of mitogen-activated protein kinases , inclu-ding extracellular signal-regulated kinase ( ERK) and c-Jun N-terminal kinase ( JNK) , in the glioma cells , while the ex-pression of survivin was inhibited .CONCLUSION:GDC-0032 inhibits U251 cell growth by inhibition of cell viability and cell cycle progression.GDC-0032 also induces DNA damage of U251 cells.The anticancer activity of GDC-0032 is associ-ated with increasing the activity of ERK and JNK and downregulating the expression of survivin .
