Objective To quantitatively analyze the dynamic posture in patients with early stage Pakinson disease (ESPD) by using dynamic posture equilibrium equipment. Method Thirty two ESPD patients were recruited in this study, in which, 10 was at Hoehn-Yahr stage 1, 9 at Hoehn-Yahr stage 1.5, 13 at Hoehn-Yahr stage 2. Thirty two age and gen?der matched healthy subjects served as a control group. The sensory organization test (SOT), motion coordination test (MCT), adaptive test (ADT), walk across were performed in those two groups using NeuroCom smart dynamic posture equipment. Results The average composite scores for SOT were 64 and 79 in ESPD patients and control group(P=0.032). The eqilibrium ratio of vision and vestibular sense were obviously lower in ESPD patients than in the control group ( 73.55±3.15 vs. 82.45±3.53, P=0.037;45.25±4.25 vs. 66.43±6.98, P=0.021). MCT showed that ESPD patients had a higher abnormality ratio of centre-of-gravity position compared with controls ( 70.3%vs. 7% )(P<0.001). ESPD pa?tients had 33% and 57% abnormality in ADT and Walk Across, which were obviously higher compared with control group (P<0.001). Conclusions ESPD patients have different degrees of posture disorders and posture equilibrium assess?ment at early stage is beneficial to rehabilitation training.

A simple, reliable and sensitive liquid chromatography-isotope dilution mass spectrometry (LC-ID/MS) was developed and validated for quantification of olanzapine in human plasma. Plasma samples (50 microL) were extracted with tert-butyl methyl ether and isotope-labeled internal standard (olanzapine-D3) was used. The chromatographic separation was performed on XBridge Shield RP 18 (100 mm x 2.1 mm, 3.5 microm, Waters). An isocratic program was used at a flow rate of 0.4 m x min(-1) with mobile phase consisting of acetonitrile and ammonium buffer (pH 8). The protonated ions of analytes were detected in positive ionization by multiple reactions monitoring (MRM) mode. The plasma method, with a lower limit of quantification (LLOQ) of 0.1 ng x mL(-1), demonstrated good linearity over a range of 0.1 - 30 ng x mL(-1) of olanzapine. Specificity, linearity, accuracy, precision, recovery, matrix effect and stability were evaluated during method validation. The validated method was successfully applied to analyzing human plasma samples in bioavailability study.

Objective:To investigate the clinical significance of MRI dynamic enhancement in defining the upper edge of adenocarcinoma of esophagogastric junction.Methods:The clinical data of 73 patients with adenocarcinoma on the esophagogastric junction operated from Jul 2018 to Aug 2019 in the Affiliated Cancer Hospital of Zhengzhou University were retrospectively analyzed. All patients underwent MRI examination within one week before surgery. First, the T 2WI, diffusion-weighted imaging and dynamic enhanced images of each patient were carefully observed to define the tumor location, size, shape, signal and enhancement mode, then the distances between the upper edge of the tumor and the cardiac incisure on MRI dynamic enhancement were measured independently, and compared with the measured distance in surgical fresh specimens. Results:The mean location of tumor upper edge measured in MRI of 73 patients was (1.75±1.98)cm, while measured in the surgical specimen was (1.72±1.97)cm. There was no significant difference between the two groups ( t=0.572, P=0.569). The intraclass correlation efficient between the two groups was excellent (ICC=0.974, 95% CI: 0.959-0.984, P<0.01). Conclusion:The measurement result of tumor upper edge in MRI is basically consistent with that of surgical specimens. MRI can be used to locate the tumor upper edge for adenocarcinoma of esophagogastric junction before operation.
