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.

This paper was aimed to study the influence ofBu-Shen Hua-TanFang (BSHTF) on the learning and memory function of diabetes mellitus (DM) rats. A total of 50 3-month-old male Wistar rats were randomlydivided into the control group, model group and 3 BSHTF groups (i.e., high-, middle-, and low-dose). A total of 35 mg·kg-1 streptozotocin (STZ) was intraperitoneally injected into the model and BSHT group. The same volume of citric acid-sodium citrate buffer solution was intraperitoneally injected into the control group. The intragastric administration of BSHTF at the dose of 20, 10, and 5 g·kg-1 was given to the BSHTF groups, respectively. The behavior and content of serum 3-deoxyglucosone (3-DG) were detected among DM rats after 30 days. The results showed that the levels of serum glucose in the model group and the BSHTF groups were obviously higher than that of the control group (P < 0.01). The swimming time to platform of rats in the model group was obviously prolonged compared to the control group with significant difference from the second day on (P < 0.01). The required time in different BSHTF intervention groups was obviously decreased compared with the model group from the 4th day (P< 0.05). The level of serum 3-DG in rats of the model group was obviously higher than that of the control group (P < 0.01). The level of serum 3-DG in rats of the middle-dose BSHTF group was obviously decreased compared with the model group (P < 0.05). It was concluded that BSHTF was able to improve the cognitive impairment among DM rats by reducing the levels of serum glucose and serum 3-DG.

Objective To study whether IL-1β, a catabolic factor of cartilage metabolism, induces premature senescence of articular chondrocytes, and whether caveolin-1 mediates IL-1β-induced cellular senescence. Methods Cultured human articular chondrocytes were stimulated with 10 ng/ml IL-1β. Cellular senescent phenotypes were analyzed by cellular morphology, cell growth arrest (flow cytometry), telomere erosion (Southern blotting), life span (population doublings), and specific senescence-associated β-galac-tosidase (SA-β-Gal) activity. Expression level of caveolin-1 was modulated by anti-sense oligunucleotide or transfection of caveolin-1 gene. Caveolin-1 protein was analyzed by Western blotting. Results Incubation of chondrocytes with IL-1β markedly increase the percentage of cells in G0/G1 phase and reduce the percentage in S phase. Single stimulation with IL-1β enables chondrocytes to become big and flat, and SA-β-Gal activity in chondrocytes is enhanced. Repeated stimulation with IL-Iβ resulted in accelerats erosion of mean telomere length, and shortens life span. Down-regulation of caveolin-1 with anti-sense oligonucleotide significantly inhibits the features of chondrocytes senescence induced by IL-1β. In contrast, caveolin-1 overexpreasion enhanced SA-β-Gal activity in the chondrocytes. Conclusion IL-1β induces features of stress-induced premature senescence and telemere-dependent replicative senescence of articular chondrocytes, which is mediated by caveolin-1. These data suggest that IL-1β induces premature senescence of articular chondro-cytes by upregulation of caveolin-1, which facilitates the development of osteoarthritis.
