ABSTRACT
Objective To explore the characters of lower urinary tract symptoms (LUTS) in patients with Parkinson's Disease (PD).Methods From Oct 2013 to Jun 2016,after evaluating of movement disorder by modified Hoehn-Yahr(H-Y) scale and LUTS by international prostate symptom score (IPSS),urodynamic study was performed in PD patients with LUTS.The incidence of every symptom of LUTS,the relationships between the IPSS categories and urodynamic study were analyzed.Results 64 patients (containing 26 male and 38 female) with 40-80 (62.7 ± 10.2) years old were included.2,4,30,19,12 and 6 patients were belonged to modified H-Y scale 1-4,respectively.Frequency (50 patients,78.1％) was the most common LUTS,while frequency all day (20 patients,31.3％) was the most common symptom for the most severe LUTS.IPSS was 1 7.5 ± 7.8 (4-35) and quality of life was 5.1 ± 0.6 (4-6) for the patients.There was no significant correlation between modified H-Y scale and IPSS (P ＞ 0.05).According to the criteria of IPSS,28 patients (43.8％) only had irritative symptoms,3 patients (4.7％) only had obstructive symptoms,while 26 patients (40.6％) had mixed symptoms and 7 patients (10.9％) belonged to no one.Urodynamic study showed 11 patients (39.3％) with only irritative symptoms had detrusor overactivity(DO),6 patients (23.1％) with mixed symptoms had DO + bladder outlet obstruction (BOO) or DO + detrusor underactivity,however,there was no one with BOO in the three patients with only obstructive symptoms.Conclusion Frequency was the most common LUTS,while frequency all day was the most common symptom for the most severe LUTS in PD patients.Irritative and mixed symptoms were common in PD patients with LUTS,but the urodynamic results were not consistent with the category of LUTS in most of the patients.LUTS severity was not correlated with movement disorders in PD patients.
ABSTRACT
Objective To evaluate if replication-defective herpes simplex virus mediated kynurenine aminotransferase Ⅱ (HSV-KAT Ⅱ) could inhibit detrusor overactivity (DO) in rats with spinal cord injury by bladder wall injection.Methods From June 2012 to July 2013,48 male Wistar rats with T10 spinal cord transection (SCT) were randomly divided into normal saline group,HSV group and HSV-KAT Ⅱ group (n=16 each group).Normal saline (40 μl),HSV or HSV-KAT Ⅱ (40 μl,1×107 plaque forming unit viruses) was injected into the rat bladder wall of according group by 1 week after SCT.Three weeks after injection,cystometry was performed and the virus transfected efficiency,expression of KAT Ⅱ in L6-S1 dorsal root ganglia were examined.Results The DO number,DO amplitude,maximum voiding pressure and volume inducing voiding were decreased significantly by 59.6％-61.1％,21.6％-24.2％,30.3％-34.4％ and 44.1％-46.5％ (P＜0.01),while voiding efficiency,the time to first DO were increased significantly by 40.7％-47.7％ and 30.1％-49.0％ (P＜0.01) in the HSV-KAT Ⅱ group compared with normal saline group and HSV group.However,the leaking volumes were no significantly different among the 3 groups (P＞0.05).The relative intensity of KAT Ⅱ protein (0.50±0.13 versus 0.28±0.07,P＜0.05) and mRNA (0.78±0.06 versus 0.51±0.08,P＜0.01) were increased significantly in HSV-KAT Ⅱ group than those in HSV group.Conclusion HSV-KATⅡ bladder wall injection inhibits DO and may improve detrusor-sphincter dyssynergia in rats with spinal cord injury.
ABSTRACT
Objective To explore the effect of hypoxic preconditioning on the activity and gene expressions of glu-cose transporters in the cultured rat hippocampal neurons and astrocytes under anoxic condition. Methods The cultured rat hippocampal neurons and astrocytes were treated for 6 days by intermittently exposing to hypoxic gas mixture (1% O_2, 10% CO_2, 89% N_2) for20 min each day. 24 h after the last hypoxic exposure, the cells were exposed to anoxic gas mixture (10% CO_2, 90% N_2) for 6 h, and the uptake rate of [~3H]-2-deoxyglucose (2-DG), the levels of glucose transporter GLUT1 and GLUT3 mRNAs and the cell survival rate were examined im-mediately after anoxic exposure. Results Neurons and astrocytes preconditioned with hypoxia showed higher 2-DG uptake rates and increased expressions of GLUT 1 mRNA in the astrocytes and GLUT 1 and GLUT 3 mRNA in the neurons. The preconditioned neurons also showed an increased tolerance to anoxia. Conclusion Hypoxic precon-ditioning up-regulates the activity and gene expressions of glucose transporters of hippocampal neurons and astro-cytes under anoxic condition.
