Parkinson's disease(PD) is the most common neurodegenerative movement disorder and ?-synuclein plays an important role in its development.Using the genetically tractable Saccharomyces cere-visiae as a model system,the phenotypic repercussions and potential mechanisms of ?-synuclein-induced cytotoxicity are characterized through modulating its expression level and other cellular factors.Aggrega-tion-induced toxicity is more dramatic upon elevated expression of ?-synuclein than that induced at moder-ate levels of expression.The induced toxicity is also enhanced by reagents such as dimethyl sulfoxide,which increase intracellular levels of phospholipid and membrane,as well as ferrous ions and hydrogen peroxide,both of which cause oxidative stresses in yeast cells.In contrast,over-expression of yeast homologue of hu-man chaperone DJ-1,YDR533C,markedly alleviate the inhibition of growth afflicted by exogenous expres-sion of ?-synuclein.Taken together,the data presented suggest a role for protein folding machinery together with quality control system in dealing with the aggregation of ?-synuclein.

Objective To identify the changes of morphological development status on minority students in China from 1985 to 2005. Methods We selected a total of 15 groups of the Chinese minority students as subjects of the study, including Mongolian, Hui, Uygur, Zhuang, Korean, Tibetan, Yao, Li, Qiang, Buyi, Dong, Miao, Tu, Salar, Kirgiz, with data from the Chinese national survey on students' physical fitness and health condition in 1985, 1995, 2000 and 2005. Height, weight and waist of the subjects were calculated and analyzed. Results From 1985 to 2005, the growth and characteristics of height in the Chinese minority students had a similar increase when comparing to the Han students, but with different degrees. However the growth rate was gradually decreasing. The average heights of Kirgiz, Korean, Salar and Mongolian schoolboys aged 18 years old were 170 cm, being 170.91 cm, 170.47 cm, 170.29 cm and 170.27 cm, respectively, which were close to that of the Hart students. Some minority students had a substantial increase of body weight. However, the waist of some minority students decreased. Only a few groups of minority students had increasing waist, such as Mongolian and Korean rural boys, Mongolian, Zhuang, and Korean rural girls, with the growth being 0.101 cm, 0.095 cm, 0.126 cm, 0.163 cm and 0.107 cm, respectively. Uygur, Mongolian, Kirgiz and Korean students had the morphological development similar to Han urban students, especially Uighur boys and girls. Conclusion From 1985 to 2005, The height, weight and waist of Chinese minority students had an overall increase at different degrees. In order to improve the physical fitness of minority students, awareness on nutrition and health education of both students and parents should be strengthened. Surveillance and programs on growth, development and health status of the minority children and adolescents should also be carried out continuously.

Objective To explore the improvement of core symptoms and detailed function in children with attention deficit hyperactivity disorder (ADHD) after treatment with methylphenidate extended-release tablets, and analyse the relationship between core symptoms reduction and detailed function improvement. Methods One hundred and fifty-six children with confirmed ADHD were rated with Swanson, Nolan, and Pelham, Version Ⅳ (SNAP-Ⅳ)Scale before treatment, then methylphenidate extended-release tablets were orally administered 18 mg once daily for 1 month, and children were rated again by means of SNAP-Ⅳ Scale and detailed function improvement questionnaire. The core symptoms reduction and detailed function improvement were observed, and their relationship was analysed. Results The primary mean scores of each factor in SNAP-Ⅳ Scale decreased significantly after treatment with methylphenidate extended-release tablets(P< 0.001). The reduction rate of factor IOWA/I/O was the most significant (>50%), followed by ADHD-H/Im and ADHD-In. The performance of school study, homework doing and social behavioral function was improved, and the detailed function was significantly improved. The reduction rate in ADHD-In factor was significantly correlated with improvement of school study and homework doing (P<0.01). The reduction rate in ADHD-H/Im factor was significantly correlated with improvement of social behavioral function(P<0.05). Conclusion Methylphenidate extended-release tablets play a role in both core symptoms reduction and detailed function improvement in children with ADHD, and core symptoms reduction is related to detailed function improvement to some degree. Methylphenidate extended-release tablets exert different effects on different detailed function.

OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.

METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).

RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.

CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.

Objective:To prepare the ocular thermosensitive gel of atropine sulfate and study its in vitro release. Methods: The gel formula was optimized by central composite design response surface methodology. The influences of the amounts of poloxamer 407 (P407) and poloxamer 188(P188) on gelling temperature before and after the dilution with simulated tear fluid were investigated. A membraneless dissolution model was used to determine the gel erosion and in vitro release. Results:The optimized gel formula was as follows:23% P407 and 5% P188. The deviations between the measured values and predicted values were all lower than 5%. The in vitro release experiment showed that the gel erosion and the drug release fitted zero-order kinetics equations with promising correlation, indicating a dissolution-controlled release mechanism. Conclusion:The optimization of the ocular thermosensitive gel of atropine sul-fate can be achieved by central composite design response surface methodology with good estimation. The thermosensitive gel with sus-tained drug release property meets the design requirements.
