Objective To investigate the incidence and risk factors of hallucination in patients with Parkinson’s disease (PD) by using a questionnaire. Methods Ninety-one patients with PD from outpatient and inpatient departments of Neurology and 38 healthy subjects were recruited. Mini-mental state examination (MMSE), unified Parkinson's disease rating scale-Ⅲ(UPDRS-Ⅲ), Hoehn-Yahr, interleukin 6 (IL-6) and C-reactive protein (CRP) were examined in all PD. According to the PPQ-B scores, the PD patients were divided into two groups:the hallucination group (PPQ-B≥1) and non-hallucination group (PPQ-B=0). Logistic regression model was used to explore the risk factors. Results Twen?ty-nine of 91 patients had hallucination and the incidence was 32%. Age and the levels of IL-6 and CRP were signifi?cantly higher in hallucination group than in non-hallucination group. Meanwhile, the duration of illness and MMSE were significantly higher in hallucination group than in non-hallucination group. Logistic regression revealed that the age and duration of illness were independent risk factors of hallucination and the Odds Ratios (OR) were 1.09 (95% CI:1.04~1.32, P<0.05) and 1.43 (95%CI:1.21~1.87, P<0.05), respectively. The risk of hallucination increased by 51%and 59%for each doubling of IL-6 and CRP levels in PD patients and the ORs were 1.51 (95%CI:1.13~2.11, P<0.05) and 1.59 (95%CI:1.07~2.66, P<0.05), respectively. Conclusions Controlling the levels of serum IL-6 and CRP plays an impor?tant role in delay or prevention of the hallucination of PD patients.

BACKGROUND: In the clinical therapy for orthopedic diseases, the traditional administration easily induces the great fluctuation of drug concentration and side effect, and implanted drug carrier material hydroxyapatite (Hap) cannot be used in human's load bearing parts due to its poor mechanical performances, and poly-L-lactic acid (PLLA) is effortlessly degraded to acid byproducts. Drug carriers made from Hap/PLLA are supposed to not only persist releasing drug onto the lesion and reduce the side effect,but also obtain strength enhancement and eliminate tissue inflammatory reaction in favor of bone regeneration.OBJECTIVE: To observe the preparation of absorbable target control-release drug carrier and simulate the application of drugs.DESIGN: Observation trial.SETTING: Chongqing Institute of Technology and Wuhan University of Technology.MATERIALS: Tails of albino rats and PLLA (offered by Biological Center of Wuhan University of Technology), pepsin (1:10 000, Sigma company), Ca(OH)2, strong phosphoric, NaOH, glacial acetic acid, phosphate buffer (pH=7.4), 1,4-dioxane, absolute alcohol (Analytical reagent available on market).METHODS: The experiment was carried out in Chongqing Institute of Technology and Wuhan University of Technology. ①Type Ⅰ collagen (Col)was prepared by acid dissolution and alkali purification methods. Hap/Col bone-like biomimetic composite was synthesized through self-assembly mechanism of materials simulating in vitro biomineralization process of nature bone. X ray diffraction analysis and transmission electron microscope were applied to observe the characterization of composite's structure and morphology. ②The resultant product of HAP/Col composite was further synthesized with PLLA to prepare the three-dimensional porous reservoir type carrier for controlled release of drug employing thermal-induced phase separation technique. Scanning electron microscope, material test machine and specific gravity test method were used to investigate the pore structure and mechanical property of carrier material. ③The prepared Hap/Col/PLLA drug carrier was loaded with bromothymol blue to investigate in vitro control-release characteristic in simulated body fluid.MAIN OUTCOME MEASURES: ①Characterization of structure and morphology of Hap/Col bone-like biomimetic composite; ②Evaluation on the property and preparation technique of Hap/Col/PLLA drug carrier; ③Assessment on results of in vitro control-release trail of model composite.RESULTS: ①Hap nanocrystals formed as slender needles aligning with its crystalline c-axis preferentially oriented.②Hap/Col/PLLA drug carrier possessed apt pore configuration and physical properties for drug controlrelease.③In vitro release test by model compound revealed an approximate zero-orderslow release prior to its 80% release percentage.CONCLUSION: Hap/Col composite material is similar with natural bone, and Hap/Col/PLLA reservoir carrier can control drug release.
