BACKGROUND: Studies demonstrated that vertebral endplate can be remodeled during intervertebral disc degeneration.However,the relationship between morphology of the vertebral endplate and intervertebral disc degeneration remains poorly understood.OBJECTIVE: To explore the relationship between the morphology of the vertebral endplate and the lumbar disc herniation.METHODS: Forty cases without previous spine disorder and sixty-two cases symptomatic lumbar disc herinations lumbar vertebral were scanned by using spiral CT.Scan range was from superior L4 to superior S2.Scan protocols as below: 140 kV,345 mAs,FOV 160 mm,layer of thick 1 mm,pitch 1.0.Original images were carried through three-dimensional reconstructions using O2 image work station,W300,C80,ZOOM=1.5,Expand 1.Intervertebral disc maximum anteroposterior,transverse diameter,circumference,area and shape were measured based on curve planar reconstruction.RESULTS AND CONCLUSION: Endplate shape was strongly related to disc herniation(all the P value < 0.01).Endplate area was a less significant factor L4/5 in men and L5/S1 in men and females(P < 0.05).The shape of the intervertebral body endplate margin is an important factor contributing to the development of disc herniation at L4/5 and L5/S1.

Objective:To evaluate the predictive value of pretreatment platelet-to-lymphocyte ratios (PLRs) in response to neoad-juvant chemotherapy and prognostic outcome in patients with International Federation of Gynecologists and Obstetricians (FIGO) Stag-es IB2-IIB cervical cancer. Methods:An investigation was conducted from January 2010 to December 2012 on 75 patients with FIGO Stages IB2-IIB cervical cancer, who underwent neoadjuvant chemotherapy and radical surgery in Changhai Hospital, Shanghai. A re-ceiver operating characteristic (ROC) curve was used to determine the best PLR cut-off value in predicting the response to neoadjuvant chemotherapy. The relationships between the pretreatment variables and the response to neoadjuvant chemotherapy were assessed in univariate and multivariate settings. The overall three-year survival rates were analyzed using the log-rank test and Cox regression mod-el. Results:The response to neoadjuvant chemotherapy was associated with PLR. At the threshold of 123.0, the PLR was 88.5%sensi-tive and 52.2%specific. Multivariate analysis showed that the low independent PLR predicted the response to neoadjuvant chemothera-py well. Based on the log-rank test, the three-year survival rate was lower in patients with PLR >123.0 than those with PLR <123.0 (59.8%vs. 82.4%), but no statistically significant differences were observed between them (P=0.116). Mono-factorial analysis showed that vascular invasion (a tumor that is>4 cm in diameter) and lymph node metastasis influenced the three-year survival rate. In the Cox regression model, only the lymph node metastasis was identified as an independent risk factor for poor prognosis (RR:5.375;95%CI:1.351-21.379; P=0.017). Conclusion: Pretreatment PLR is an easily measured, reproducible, and inexpensive marker of systemic in-flammation and thus shows a prognostic and independent predictive value for the response to neoadjuvant chemotherapy in cervical can-cer. However, pretreatment PLR is not a clinically significant factor for the assessment of cervical cancer prognosis.

Analysis and comparison of DWIBS sequences, sequences of SPACE provides a clear display of the brachial plexus, and two sets of image sequence average signal-to-noise ratio (SNR) and the contrast to noise ratio (CNR). Results:A total of 35 cases 70 lateral brachial plexus after coronary DWIBS is clearly displayed on the sequence;the partial medial cord of brachial plexus, beams and lateral beams can also be displayed in the SPACE sequence. SPACE sequence of image signal-to-noise ratio and contrast noise ratio than the DWIBS sequence, and the difference is statistically significant. Conclusion:SPACE sequence can clearly show the brachial plexus, and DWIBS sequences compared to the normal image has a higher resolution of the brachial plexus.

BACKGROUND: Cleistocalyx operculatus is a dried alsbastrum of myrtle. It is reported that cleistocalyx operculatus extracts can improve cardiac contraction through inhibiting the activity of Na+/K+-ATPase, and decrease rate of contraction. Do cleistocalyx operculatus extracts have the biological activity of antioxidation?OBJECTIVE: To observe the effects of cleistocalyx operculatus on oxidative injury of PC12 nerve cells induced by H2O2.DESIGN: Non-randomized controlled study.SETTING: State Key Laboratory of Bioreactor Engineering, New World Institute of Biotechnology, East China University of Science and Technology.MATERIALS: The experiment was conducted at New World Institute of Biotechnology, State Key Laboratory of Bioreactor Engineering of East China University of Science and Technology, from May to November 2002.Eight adult male Kunming mice were selected. PC12 nerve cells were supplied by Shanghai Cell Institute of the Chinese Academy of Sciences.METHODS: Model of oxygenic injury of PC12 nerve cells was estabPC12 cells were cultured in 96-well plates. Cleistocalyx operculatus was diluted with RPMI1640 culture medium into five concentrations of 0.001,0.01, 0.1, 0.5 and 1 g/L with 3 wells in each concentration; each well had 2×103 cells. Blank control group, or non-drug culture medium group, was set. Under the standard condition, cells were cultured for 48 hours and ascells were inoculated in 96-well plate with the density of 2×103 for 24-hour wall adhering, and then divided into normal control group (normal cell without H2O2 or cleistocalyx operculatus extracts), 0, 0.01, 0.1, 0.5 and 1 g/L cleistocalyx operculatus. Cells in all groups except normal control group were treated with 200 μmol/L H2O2 at 37℃ for 3 hours, then cleistocalyx operculatus of various concentrations was added and survival rate was asfree radicals: PC12 cells with oxygen-derived free radicals were treated in the same way as done for cell survival rate assay and measured with CDCFH staining method.fect of cleistocalyx operculatus extracts on intracellular and extracellular oxygen-derived free radicals in PC12 nerve cells induced by oxidative injury.operculatus could protect nerve cells; however, at 0.055-1.00 g/L the effect on cell growth did not significantly differ from that of blank control extracts had no protective effect on the injury of PC12 nerve cells induced by H2O2. At 1.00 g/L, it had strong plerosis for oxidative injury of PC12 and extracellular oxygen-derived free radicals in PC12 nerve cells was increased; however, at 0.01 g/L concentration of cleistocalyx operculatus extracts, the level was lower than that in model group.dation of membrane lipid of hepatic microsome, but also protect against oxcleistocalyx operculatus extracts is related to its concentration. At 1.00 g/L,it has great capacity of oxidation plerosis, and at 0.01 g/L it can decrease the level of oxygen-derived free radicals inside and outside cells.
