Objective To develop a scale to assess Kennedy's disease (KD) based on patients' clinical characteristics and to validate its application in patients.Methods We developed KD1234 Scale following the model of Amyotrophic Lateral Sclerosis-Functional Rating Scale.Using this new scale,we assessed patients with genetic diagnosis of KD and evaluated the reliability and validity of the new scale.Reliability was analyzed using Cronbach' s α coefficient and split-half reliability.Validity was analyzed by content validity and structure validity.Results The Cronbach' s α coefficient of the total scale was 0.789 and split-half reliability coefficient was 0.868.The α of breathing with total score was 0.3-0.4,α of written,language and swallowing with the total score was 0.4-0.5,α of other items with the total score was ＞ 0.5 (P ＜ 0.01 in each of above α).Four common factors extracted by exploratory factor analysis had well correspondence between the scale construction and the theoretical construction.Factor loading was ranged from 0.541 to 0.864 for each item.The duration of the disease showed some correlation with the score of KD1234 Scale.Conclusions The KD1234 Scale demonstrates high reliability and validity.The duration of the disease indicates negative correlation with KD1234 Scale scores.The KD1234 Scale can be used in clinical research to evaluate the condition of KD patients quantitatively.

Objective To compare the concentration of 3-nitrotyrosine and tyrosine and the ratio of 3-nitrotyrosine/tyrosine in the cerebrospinal fluid (CSF) of patients with sporadic amyotrophic lateral sclerosis (SALS) and those with healthy nervous system for definiting the role of free radicals oxidative damage in pathogenesis of SALS. Methods Subjects consisted of 15 patients with SALS and 15 patients with norml nervous system who underwent lumbar anesthesia for surgery. Their CSF was analyzed by using high performance liquid chromatography (HPLC). Results The 3-nitrotyrosine concentration was higher in patients with SALS (228.52?124.30 nmol/L) than that in controls (112.86?47.10 nmol/L) (P

Objective To explore the significance of serum myoglobin detection in the diagnosis and evaluation of Kennedy`s disease (KD).Methods The level of serum myoglobin (Myo) was detected in 60 KD patients and 30 amyotrophic lateral sclerosis (ALS) patients.Results The serum Myo level and abnormal rate in KD group were significantly higher than those in ALS group (all P<0.001).The serum Myo level was positively related with the disease course of KD (r=0.665,P<0.01).There was no significant difference of serum Myo level and disease course of ALS (r=-0.047,P>0.05).There was no overlap of serum Myo level between the two groups.There was no significant difference of serum Myo level and CAG repeated number of ALS (r=-0.193,P>0.05).Conclusion Myo is likely as an easy and sensitive biomarker, used to identify the KD and special type of ALS, and used in the evaluation of the KD condition in the future.

Objective This study was performed to investigate the effect of hypoxia on glucose-6-phosphate isomerase (G6PI) expression and cell cycle of fibroblast-like synoviocytes from synovium of rheumatoid arthritis (RA) and osteoarthritis (OA) under hypoxia or normoxia.Methods Fibroblast-like synoviocytes were cultured with either of hypoxia (3％ oxygen) or normoxia (21％ oxygen) for 24 hours.The mRNA expression of G6PI and HIF-1α was tested by PCR quantification,while the protein levels of G6PI and HIF-1α were measured by western blot.Cell cycle was performed by FACS.T-test and Mann-Whitney U were used for statistical analysis.Results The expression levels of G6PI mRNA under hypoxia in RA were higher than those of OA (2.6±0.4 vs 1.5±0.4,P＜0.05).The protein levels of G6PI in RA were higher than those of OA (P＜0.05).The expression levels of HIF-1α mRNA under hypoxia in RA were higher than those of OA (2.9±0.8vs 1.4 ±0.4,P＜0.05).The protein levels of HIF-1α in RA were higher than those of OA (P＜0.05).The G1 phase ratio of cell cycle was decreased significantly under hypoxia than those of normoxia in RA ELs (t=1 1.31,P＜0.05).The S and G2 phase ratio of cell cycle were increased.Conclusion Hypoxia upregulates G6PI and HIF-1α expression and improves proliferation in fibroblast-like synoviocytes.

Objective To investigate the influence of classically activated macrophage (M1) on the proliferation of rheumatoid arthritis (RA) fibroblast-like synovial (FLS) and osteoarthritis (OA) FLS proliferation.Methods Human monocytes leukemia cells (THP)-1 were induced into M1 by lipopolysaccharides (LPS) and interferon gamma (IFN-γ),M1 specific surface molecular markers human leukocyte antigen (HLA)-DR and CD197 were detected by flow cytometry (FCM).RA-FLS and OA-FLS were co-cultured with M1 by transwell chambers,the proliferation of RA-FLS and OA-FLS were observed by crystal violet staining assay.MTS was used to detect cytokines secreted from M1 on the multiplication of RA-FLS and OA-FLS.TNF-α and IL-12 were detected by enzyme linked immunosorbent assay (ELISA).Paried student t test was used for statistical analysis.Results THP-1 were induced into M1 by LPS and IFN-γ,the expression rates of M1 surface specific molecular markers HLA-DR and CD197 were 78.25％ and 87.96％.Crystal violet staining showed that RA-FLS and OA-FLS proliferation were significantly inhibited after co-cultured with M1 48 h,RA-FLS and OA-FLS of each vision under microscope in co-culture groups were (64 ±30) and (85 ±23) respectively,while the RA-FLS and OA-FLS in separate culture groups were (467±87) and (263±78) respectively,the difference was statistically significant (t=7.459,3.791;P＜0.05).MTS assay indirectly reflected that the cytokines from M1 suppressed RA-FLS and OA-FLS proliferation (t=-7.155,-8.111;P＜0.05).The concentration of TNF-α in cell culture supernatants secreted from RA-FLS group and RA-FLS/M1 co-culture group respectively were (0.024±0.01 1) ng/ml and (0.832±0.241) ng/ml respectively,the concentration of IL-12 from the two groups were (0.033±0.015) ng/ml and (0.372±0.122) ng/ml respectively.TNF-α from OA-FLS and OA-FLS/M1 co-culture group respectively were (0.031±0.017) ng/ml and (0.852±0.323) ng/ml,IL-12 were (0.012±0.009) ng/ml,(0.373±0.144) ng/ml.Compared with FLS separate culture group,the concentration of TNF-α and IL-12 were obviously elevated (t=-4.997,-4.777,-4.407,-4.334;P were all ＜0.05).Conclusion M1 can significantly inhibite RA-FLS and OA-FLS proliferation,this may be related to the increased concentration of TNF-α and IL-1 β in from cell culture supernatant.

Objective To study changes of trigemino-cervical reflex (TCR) in patients with Kennedy's disease (KD). Methods The parameters of TCR were analyzed among patients with KD, amyotrophic lateral sclerosis and healthy controls. Results The parameters of ipsilateral P19, N31, A and contralateral P19, N31, A among patients with KD were (23.91±4.84), (35.45±4.76) ms, 1.24± 0.33 and (24.34±4.82), (36.20±4.91) ms, 1.19±0.25, respectively. Compared with the healthy controls((18.37±2.16), (28.50±1.56) ms, 1.90±0.43; (18. 72±2. 18), (29. 19±1.43) ms, 1.84 ± 0. 40), the difference in each parameter was significant (ipsilateral : t = 5.77, 8. 19, -6. 64; contralateral:5.05, 7.62, -7.77, all P<0.01). Conclusion The parameters of TCR were abnormal in KD patients, indicating that the trigeminal nerves and the bulbar may be involved in the disease.
