Objective To observe the changes of retinal nerve fiber layer (RNFL) thickness and its correlation with visual field mean defects(MD)in Parkinson's disease (PD). Methods Fifteen eyes of 15 PD patients in early stage and 18 eyes of 18 normal controls undertook RNFL examination by Stratus OCT-3. Circular scans (diameter is 3. 46 mm) were taken around the optic nerve head including eight quadrants (superior, inferior, temporal, nasal, temporal-superior, temporal-inferior, nasal-superior and nasalinferior). The RNFL thickness in different quadrants in the two groups was analyzed. The visual field of PD patients was measured by central 30-2 program of Humphery750 visual field analyzer, and the MD was recorded. The correlation between RNFL thickness and MD was analyzed by linear correlation and regression analysis. Results RNFL thicknesses of superior, inferior, temporal, nasal, temporal-superior, temporal-inferior, nasal-superior, nasal-inferior and average RNFL thickness in the control group were (132.7±17.4), (141. 5±15. 3),(83. 2±17. 5), (83.7±22.3) ,(120.8±21.2), (117. 9±24.5) ,(109.6±20. 6),(110.2±27.7), and(109. 9±8. 5) μm respectively, while in the PD group they were (128.1±25.3),(128. 6±13. 2),(68. 7±13. 5),(76. 5±17. 8),(102. 6±23. 7), (103.3±14.1) ,(101.2±20.9),(96.6±15.0),(102.3±11.9) μm . Compared with each other, the differences of RNFL thickness of inferior, temporal, temporal-superior, temporal-inferior and average RNFL thickness were statistically significant (t = 2. 595, 2. 700, 2. 330, 2. 153,2. 131;P = 0. 014, 0. 011, 0. 026, 0. 040, 0. 041). There was a close negative relationship between average RNFL thickness and MD in PD patients (r= -0. 933, P<0. 0001). Conclusions RNFL thickness was significantly thinner in PD patients than that in the normal controls. There was a negative relationship between RNFL thickness and MD in PD patients.

Objective To evaluate visual field changes in early mild Parkinson's disease.Methods A total of 66 eyes of 33 cases with early mild Parkinson's disease and 72 eyes of 36 age-matched normal individuals were enrolled into the study.Humphrey Field Analyzer Ⅱ was applied for central visual field test.The visual field indices of mean deviation (MD) and pattern standard deviation (PSD) were analyzed to evaluate the location and the characteristics of visual field defect in this study.Results Visual field indices MD (-3.4±2.5) dB was significantly changed in patients with PD when compared to the controls (-0.6 ± 1.7) dB.PSD (4.3±2.6) was significantly higher in patients with PD than that in the control group (2.1 ± 1.8) dB.Glaucoma hemifield test (GHT) assessment was within normal limits in the controls.Of the 33 patients (66 eyes) in PD,GHT showed outside normal limits in 31 eyes,borderline in 8 eyes,and within normal limits in 27 eyes.31 eyes outside normal limits appeared glaucomatous visual field defects,in which 16 with nasal step and 5 with arcuate defect.Conclusions Visual field indices including MD and PSD in early mild patients with PD were significantly worse than that in the controls group.GHT abnormalities could be found in early mild PD patients with visual field defects,including pericentral scotoma and nasal step,which mimicked glaucomatous changes.

Objective:To explore the mental health status of the first-degree relatives of the heroin addicts. Methods: Three hundred twenty first-degree relatives of the heroin addicts were evaluated with SCL-90. Results: The scores of somatization, depression, anxiety, paranoia, and psychiatric factor among the first-degree relatives were significantly higher than the national norm. The first-degree relatives of heroin addicts who had addicted more than 5 years had significantly higher score than the relatives of heroin addicts who had addicts less than 5 years. Conclusion: The mental health condition of the first-degree relatives of heroin addicts was poor, especially those relatives of heroin addicts who have addicted for more than 5 years.

Abstract?AlM:To study the thickness changes of retinal nerve fiber layer ( RNFL) in Parkinson's disease ( PD) .?METHODS:Fifteen eyes of 15 PD patients in early stage and 18 eyes of 18 controls were chosen to take RNFL examination by optical coherence tomography ( OCT ) . Circular scans were taken around the optic nerve head (diameter = 3. 46mm) to record the features of RNFL. Scanning areas included eight quadrants of the temporal, superior, nasal, inferior, inferior-temporal, superior-temporal, inferior-nasal and superior-nasal quadrant. RNFL thickness was comparatively analyzed in eight quadrants and the average level in two groups.?RESULTS: RNFL thickness in two groups in temporal, superior, nasal , inferior, temporal- inferior, temporal-superior, nasal-inferior, nasal-superior were: ( control/PD) 83. 2 ± 17. 5μm/68. 7 ± 13. 5μm, 132. 7 ± 17. 4μm/128. 1 ± 25. 3μm, 83. 7 ± 22. 3μm/76. 5 ± 17. 8μm, 141. 5 ± 15. 3μm/128. 6± 13. 2μm, 117. 9 ± 24. 5μm/103. 3 ± 14. 1μm, 120. 8 ± 21. 2μm /102. 6 ± 23. 7μm, 110. 2 ± 27. 7μm/96. 6 ± 15. 0μm, 109. 6 ± 20. 6μm/101. 2 ± 20. 9μm. The average RNFL thickness in controls was 109. 9 ± 8. 5μm while it showed 102. 3 ± 11. 9μm in PD group. RNFL thickness in inferior, temporal, inferior-temporal, superior-temporal and the average RNFL thickness were statistically different in two groups ( t= 2. 595, 2. 700, 2. 153, 2. 330, 2. 131;P= 0. 014, 0. 011,0. 040,0. 026,0. 041).?CONCLUSlON: RNFL thickness in inferior, temporal, inferior temporal, superior temporal and the average RNFL thickness are significantly thinner in mild PD than those in the controls.

One hundred upper limbs of Chinese children of about ten years old weredissected for the study of their arterial branches forming the superficialvolar arch.The arches were divided into four types:1)radial arterial type,2)radial-ulnar arterial type,3)median-ulnar arterial type and 4)archlesstype.The first type has the highest percentage of 46%,the second one comesnext with 34%.The archless cases occupy 19%,and only in 1% was thearch formed by branches of the median and ulnar arteries.

Object To prepare and study a suitable carrier for paclitaxel in water. Methods Cetyl chitosan (CTCS), prepared by reacting chitosan (CS) with chlorocetane under alkaline condition, was soluble and spontaneously formed nanosphere about 100 nm in diameter. And the release in vitro from paclitaxel loaded CTCS nanosphere was measured in phosphate buffer solution (PBS, pH=7 4). Results The balanced release concentration of paclitaxel was deceased and half release time (t 1/2 ) was delayed with the increase of substitution degree of alkyl. Conclusion This kind of nanosphere is an excellent carrier for paclitaxel in water.
