Objective To characterize the changes of retinal structure and visual field mean defects (MD) in early Parkinson's disease (PD) and the related factors.Methods Twenty-five patients with early stage PD and 33 normal controls were enrolled in this study.PD patients were evaluated by unified Parkinson's disease rating scale (UPDRS) and Hoehn-Yahr (H-Y) stage in off period.All subjects undertook retina of retinal nerve fiber layer (RNFL) and macular examinations by optical coherence tomography (OCT),and MD by automatic visual field analyzer.Results (1) The average thicknesses of RNFL and C11 quadrant RNFL were thinner in PD group [(96.2 ±7.6) μm and (124.4 ± 18.4) μm] than in healthy controls [(102.6 ± 5.0) μm and (135.4 ± 21.8) μm,respectively,P =0.000 and P =0.047].Moreover,PD patients had a thinner average thickness of macular[(277.2 ±9.6) μm vs (285.8 ± 12.6)μm,P=0.006],and smaller macular volume compared with controls [(10.0 ± 0.3) mm3 vs (10.3 ±0.4) mm3,P =0.006].However,there was no significant difference in MD between PD and control subjects [(0.43 ± 2.75) dB vs (-0.18 ± 1.41) dB,P =0.322].(2) Pearson's correlation analysis showed that H-Y stage was negative correlated with the average RNFL thickness (r =-0.569),average macular thickness and volume (r=-0.501 and r=-0.417) in PD patients (all P＜0.05).Conclusions PD patients have thinner average thicknesses of RNFL,C11 quadrant RNFL and macular,smaller macular volume than those in normal controls.There were no significant differences in MD between two groups.There were negative relationships between H-Y stage,and retinal thickness and volume of PD patients.

Objective: After establishing standard multi-modal therapy, prognosis of refractory and metastatic high-grade osteosarcoma remains dismal and unchanged over the last decades. Early clinical intervention to newly detected metastatic lesions is crucial and effective for better prognosis. Arsenic trioxide (ATO) is one of the oldest remedies used in traditional oriental medicine and is recently rediscovered as an immunomodulator due to its activity against other solid tumors. This study aims to evaluate the efficiency of ATO combined with first-line chemotherapy in treating pulmonary metastatic osteosarcoma patients with long-term follow-up in our institution.Methods: Osteosarcoma patients with pulmonary metastasis were intravenously administered with ATO (5-10 mg) daily combined with first-line chemotherapy for their treatment. A total of 119 patients were finally enrolled; 65 presented metastasis, and 54 relapsed with lung metastasis. Results: Two-year and five-year overall survival (OS) rates for these patients reached 52.6% and 30.9%, respectively. Only 20 cases underwent thoracotomies (16.8%). Our five-year OS was nearly similar to that of other institutions (37% in Rizzoli, Italy). We observed that combined with bone metastasis, bilateral metastasis, and >3 pulmonary nodules, incomplete resection of pulmonary lesions deteriorated the disease and significantly influenced survival as compared with all other parameters. Conclusion:Combined with conventional chemotherapy, ATO may be effective and well-tolerated as new therapeutic option for patients with nonresectable pulmonary metastatic osteosarcoma. Lung metastasectomy should be strictly selected only for populations who benefit from this treatment.

Objective To investigate the predicting value of intermedin (IMD) for the prognosis of elderly sepsis patients.Methods A retrospective analysis was conducted. Forty-one patients with sepsis, aged ≥65 years, and admitted to geriatrics intensive care unit of Aerospace Center Hospital from April 2015 to December 2016 were enrolled. Thirty healthy patients were studied as control during the same time. The expression of C-reactive protein (CRP), procalcitonin (PCT) and IMD were tested within 24 hours during hospitalization, and the acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score and prognosis was evaluated. According to APACHE Ⅱ score, patients were divided into 3 groups, 10-20 score, 21-30 score, and > 30 score group. And based on the prognosis, the patients were divided into death group and survival group. The differences of expression levels of CRP, PCT and IMD in each group were assessed. The relationship of IMD and infection index was analyzed by Pearson correlation. Receiver operating characteristic curve (ROC) was used to evaluate the prognostic value of CRP, PCT and IMD in patients with sepsis.Results Compared with the control group, the levels of CRP, PCT and IMD were significantly higher in the sepsis patients [CRP (mg/L): 114.71±40.08 vs. 4.03±2.68, PCT (μg/L): 1.338±0.812 vs. 0.007±0.001, IMD (ng/L):43.03±9.67 vs. 16.77±2.06, allP < 0.01]. With the increase of APACHE Ⅱ score, the levels of PCT and IMD were gradually increased. In APACHE Ⅱ 10-20 score, 21-30 score, > 30 score groups, PCT (μg/L) were 0.397±0.129, 1.164±0.326, and 1.999±0.888, respectively (F = 19.392,P = 0.000); IMD (ng/L) were 29.12±5.60, 40.48±4.40,52.75±4.73, respectively (F = 33.310,P = 0.000). There was no significant difference in CRP among APACHE Ⅱ score groups (F = 2.137,P = 0.132). The level of IMD was positively correlated with CRP and PCT (r1 = 0.351,P1 = 0.024;r2 = 0.617,P2 = 0.000), and there was no correlation with temperature and white blood cell count (r1 = 0.063,P1 = 0.697;r2 = 0.064,P2 = 0.692). The expression of PCT and IMD in the death groups were significantly higher than the survival group [PCT (μg/L): 1.547±0.883 vs. 1.043±0.608, IMD (ng/L): 47.44±8.23 vs. 36.80±8.13, bothP < 0.05], while CRP was not significantly different. The area under the ROC curve [AUC (95% confidence interval, 95%CI)] of IMD was larger than that of PCT and CRP [0.809 (0.675-0.943) vs. 0.680 (0.511-0.849), 0.664 (0.490-0.838)]; when cut-off value of IMD was 41.58 ng/L, the sensitivity was 75.0% and the specificity was 82.4%.Conclusions The levels of CRP, PCT and IMD were increased in elderly sepsis patients, and IMD and PCT can better reflect the severity of sepsis. IMD is more valuable in predicting the prognosis of sepsis patients.
