RNA dot blot hybridization was employed to investigate the alterations in C-myc, C-H-ras transcript levels in bone marrow and peripheral blood cells from 24 patients with acute nonlymphocytic leukemia. 10 cases of normal bone marrow cells were used as control. We found that the positive rates and intensities of expression of C-myc and C-H-ras in acute nonlymphocytic leukemia were hipher than those of normal control. The C-myc and C-H-ras expressed simultaneously in 10 patients. After having been cultured 5 days with RA and low dose Ara-C combined with low dose Harr, the C-myc transcipt level of C-myc in acute nonlymphocytic leukemia was decreased obviously.

Purpose To explore the relationship of Tei index and the concentration of plasma brain natriuretic peptide (BNP) in patients with dilated cardiomyopathy. Materials and Methods Fifty healthy individuals (control group) and fifty dilated cardiomyopathy patients (study group) were recruited in this study. BNP level was measured by enzyme-linked immunosorbent assay (ELISA). Color Doppler echocardiography were performed to measure the cardiac indices including left ventricular end-diastolic dimension (LVEDd), left ventricular end-systolic diameter (LVESd), interventricular septal thickness at diastole (IVSd), left ventricular ejection fraction (LVEF). Tei index was then calculated. The indices between the two groups were compared and correlation of Tei index and BNP with cardiac indices was analyzed. Results LVEDd, LVESd, Tei index, and BNP were significantly higher in study group than those in control group (t=14.4, 23.4, 21.9 and 22.3, P<0.01). IVSd and LVEF were significant lower in the study group (t=12.4 and 12.5, P<0.01). BNP was negatively correlated with LVEF (r= -0.266, P<0.05), and positively correlated with Tei index and LVEDd (r=0.401 and 0.326, P<0.05). Tei index was negatively correlated with LVEF and E/A (r= -0.480 and - 0.241, P<0.05), and positively correlated with LVEDd (r=0.375, P<0.05). Multiple stepwise regression analysis showed that the variates of BNP stepwise regression equation were Tei index, LVEF and LVEDd (t=5.984, -2.477 and 2.326, P<0.05); after correcting LVEF, the stepwise regression analysis showed closer relationship between Tei index and BNP (t=2.728, P<0.05). Conclusion There is correlation between Tei index and BNP. Tei index may be a good index for accurately estimating global ventricular function.

Objective To explore the effect of motor imagery on motor recovery in hemiplegic patients after stroke. Methods From May, 2015 to October, 2016, 40 hemiplegic patients after stroke were randomly divided into control group (accepted routine rehabilitation, n=20) and motor imagery group (accepted motor imagery and routine rehabilitation, n=20). They were assessed with Fugl-Meyer Assess-ment (FMA), modified Barthel Index (MBI) before and six weeks after treatment. Fractional anisotropy (FA) of the focus was measured with diffusion tensor imaging (DTI). Results The scores of FMA and MBI improved in both groups after treatment (t>5.088, P<0.001), and improved more in the motor imagery group than in the control group (t>2.124, P<0.05). The FA reduced in the focus compared with the same site of unaffected side in both groups before treatment (t>3.892, P<0.01), and there was no significant difference between two groups (t<1.144, P>0.05). FA increased in more patients of the motor imagery group (5/5) than in the control group (2/4). Conclusion Motor imag-ery can promote the recovery of motor function and activities of daily living in stroke patients, and may help the recovery of fibers in white matter.

This paper is intended to figure out how to develop and maintain the traditional Chinese medical (TCM)thesaurus in the Internet Era. The history of TCM thesaurus was reviewed. The function of TCM thesaurus in searching information in internet and the impact of internet to thesauri were discussed. Suggestions on descriptor/term selection, term relations, and thesaurus maintaining were put forward.

Nowadays,with the rapid development of science and technology of medicine,the detection rate of obstructivc azoospermia increased gradually,clinically not uncommon.Surgical treatment of obstructive azoospermia is also improved from traditional vasovasostomy and epididymovasostomy to microsurgical vasovasos-tomy and microsurgical va-soepididymostomy,and from 3-suture intussusception vasoepididymostomy to 2-suture intussusception vasoepididymostomy,then our modified reverse single needle anastomosis,and finally to the robot assisted anastomosis.Therefore,the anastomosis is more precise,the recanalization rate and the pregnancy rate have a revolutionary improvement.The robot era is coming.The article focuses on surgical treatment of obstructive azoospermia,comparison of the advantages and disadvantages of each operation,and prediction of the future direction of development.

To solve the calibration transmission problem in near-infrared ( NIR) spectroscopy, a novel model transfer method, Simple Linear Regression Direct Standard-ization ( SLRDS ) , has been presented. To investigate the validity of the proposed method, a real corn sample NIR dataset was tested and the direct standardization ( DS ) method and piecewise direct standardization ( PDS ) method were involved as a comparison. Our results indicated that SLRDS can correct compressed NIR data differences among instruments and enable the user to share corn sample PLS calibration model among three instruments, at the same time it has higher prediction accuracy, fewer parameters and simpler model than DS and PDS.

Objective To compare the impact on the ovarian reserve function after cisplatin intraperitoneal or intravenous chemotherapy in rats model. Methods Thirty 8-weeks old female Sprague Dawley rats were randomly assigned to control group (group A, n=10), intraperitoneal chemotherapy group (group B, n=10) and intravenous chemotherapy group (group C, n=10). Cisplatin was diluted by normal saline (NS) into 4 mg/ml. On the first day of chemotherapy, 0.2 ml cisplatin dilution was injected into the abdomen of rats in group B, isodose cisplatin was injected into vein and 1.8 ml NS was injected into abdomen of rats in group C, 2.0 ml NS was injected into abdomen of rats in group A for control. Feed the three groups rats and test the anti-Mullerian hormone (AMH) in serum on day 0 (just before injection), day 10 and day 20 by ELISA, count the numble of follicle in bilateral ovaries on day 20. Results (1) The levels of serum AMH in the three groups before and after chemotherapy were compared: ① comparison between groups: On day 10 and day 20 , the AMH level in group B [(64.5 ± 2.9), (68.6 ± 3.4) ng/L] and group C [(76.1±4.9), (91.3±3.9) ng/L] was significantly lower than that in group A [(120.1±5.3), (121.7±4.6) ng/L;P<0.01], AMH level in group B was significantly also lower than that in group C (P=0.000). ② Comparison within groups:the AMH level on day 0 was significantly lower than that on day 10 and day 20 in group A (P<0.01), but there was no significant difference between day 10 and day 20 (P=0.427). The AMH level on day 0 was significantly higher than those on day 10 and day 20 in group B (P<0.01) and group C (P<0.01). There was no difference in AMH level between day 10 and day 20 (P=0.124) in group B, but the level was significant lower on day 10 than that on day 20 in group C (P=0.011). (2)Comparison of the number of follicles in ovaries of three groups 20 days after chemotherapy:the follicles number in group A(35±13)was greater than that in group B (16 ± 9,P=0.003) and similar with group C (31 ± 16,P=0.474) on day 20. The follicles number in group B was significantly less than that in group C (P=0.018). Conclusions In the present study, both intravenous and intraperitoneal chemotherapy have impacts on ovarian reserve function and the latter might be more serious. The level of AMH will rise again over time after chemotherapy and rats undergo intravenous chemotherapy would recover faster. The results suggest that the ovarian reserve function need more time to recover after intraperitoneal chemotherapy. For patients with ovarian cancer who want to preserve fertility function, intravenous chemotherapy might be more appropriate.
