Objective To investigate the role of asctrocytes in the process of chronic degeneration of dopaminergic neurons in intracephalic inflammation rat model induced by intracerebroventricularly injection of lipopolysaccharide.Methods Sixty healthy male SD rats were assigned into lipopolysaccharide group or saline control group randomly.All injections were made intracerebroventricularly on right side of the rats.Ethovison software was used to measure the movement distance of rats within 30 minutes.Specific antibody for glial fibrillary acid protein (GFAP) was used in immunohistochemistry stain to detect the changes of asctrocytes in the substantia nigra of rats.Results Movement distance of lipopolysaccharide-injected rats decreased by 21.2% compared with saline-injected rats at 16 weeks after injection (t=2.54,P<0.05)by 27.0% (t=3.55,P<0.01) at 24 weeks and by 31.4% (t=3.91,P<0.01) at 28 weeks after lipopolysaccharide injection.The asctrocytes were activated obviously in the substantia nigra of lipopolysaccharide-injected group at 2 weeks,while the numbers of GFAP-positively stained cells (228.60 + 22.35) increased significantly compared with saline-injected group ( 165.20 ± 25.97) (t = 4.14,P< 0.05).The activation of asctrocytes was not found in lipopolysaccharide-injected group at 4 weeks and 12 weeks.The asctrocytes were re-activated in the substantia nigra of lipopolysaccharide-injected group at 24 weeks,while the numbers of GFAP-positively stained cells (220.00±21.01 ) increased significantly compared with saline-injected group (169.00± 19.00) (t= 4.03,P<0.05).The activation of asctrocytes was not seen at any time point in saline-injected group.Conclusions Intracephalic inflammation induces chronic degeneration of substantia nigral dopaminergic neurons in rats.The asctrocytes exhibite "acute activation-quiescing-reactivation" state,indicating that they might be involved in the mechanism of dopaminergic neurons degeneration.

A 56-year-old female patient of Han nationality presented with generalized erythema and vesicles for 6 days,as well as high fever for 2 days.Twenty days prior to hospitalization,the patient received surgical treatment combined with oral methazolamide and glucocorticoids for glaucoma.The patient had a history of allergy to sulfanilamides.On admission,the patient presented with generalized erythema,vesicles and occasional erosions with bilateral eyelid and oral involvement.Nikolsky's sign was positive.Wheezing sound was heard over the right lung.Genetic testing showed that HLA-B5901 allele was positive.The patient was diagnosed with methazolamide-induced toxic epidermal necrolysis (TEN) complicated by pneumonia,and managed with immunoglobulin (25 g/day,5 days),glucocorticoids (the largest dose equivalent to methylprednisolone 160 mg/day),fresh plasma,antibiotics,as well as other supporting and symptomatic treatments.The condition was controlled after 2 weeks,and the patient was cured and discharged from hospital after 25 days.The fact that the patient carried HLA-B5901 allele suggests that HLA-B5901 is strongly correlated with methazolamide-induced TEN or Stevens-Johnson syndrome in Chinese descendants or Han population,besides in Japanese and Korean descendants.

Objective To evaluate the colon cleaning efficacy and safety of prucalopride combined with polyethylene glycol electrollytes powder in bowel preparation for colonoscopy examination and treatment under colonoscopy in elderly patients.Methods Elderly patients who prepared for colonoscopy were enrolled from October 2014 to January 2015.They were divided into group A,B and C.Patients of group A only took polyethylene glycol electrolyte powder (137.12 g dissolved in 2 000 mL warm water,stired until completely dissolved),patients of group B took polyethylene glycol electrolyte powder (same usage as group A) combined with prucalopride 2 mg/d for one day,patients of group C took polyethylene glycol electrolyte powder (same usage as group A) combined with prucalopride 2 mg/d for three days.The bowel preparation effects,especially ascending colon and ileocecal junction and cardiovascular adverse effects in all the patients and constipation patients of three groups were compared.Student t test,chisquare test and analysis of variance were performed for statistical analysis.Results A total of 124 elderly patients were divided into group A (64 cases),group B (23 cases) and group C (37 cases).Bowel preparation scores of total colon and ascending colon-ileocecal junction of group A,B,C were 8.34±0.90 and 2.56±0.56,8.96±0.21 and 2.96±0.21,8.86±0.35 and 2.86±0.35,respectively.The cleaning effects in total colon and ascending colon-ileocecal junction of group B were better than those of group A (t=5.52 and 5.15,both P＜0.05).The cleaning effects in total colon and ascending colon-ileocecal junction of groupCwere better than those of group A (t=4.69,3.65,both P＜0.05).There was no statistically significant difference between group B and group C in cleaning effects in total colon and ascending colon-ileocecal junction (both P＞0.05).There were 33,11 and 29 constipation cases in group A,B and C,respectively.The bowel preparation scores for total colon and ascending colon and ileocecal junction of group A,B,C were 7.85±0.94 and 2.24±0.56,8.91±0.30 and 2.91±0.30,8.83±0.38 and 2.83 ± 0.38,respectively.The cleaning effects in total colon and ascending colon-ileocecal junction of group B were better than those of group A (t=6.72 and 5.49,both P＜0.05).The cleaning effects in total colon and ascending colon-ileocecal junction of group C were better than those of group A (t=104.04 and 59.65,both P＜0.05).There was no significant difference between group B and group C in cleaning effects in total colon and ascending colon ileocecal junction (both P＞ 0.05).No obvious cardiovascular adverse events were observed in the patients of three groups.Conclusions The cleaning effects of prucalopride combined with polyethylene glycol electrolytes powder are good for colonoscopy examination in elderly patients,including elderly patients with constipation,especially in ascending colon and ilecocecal junction.No obvious cardiovascular adverse events are observed.

Objective:To investigate the long-term efficacy of oral appliance treating of obstructive sleep apnea and hypopnea syndrome (OSAHS) in different periods of treatment.Methods:A total of 55 patients were included in the study.Patients were all diagnosed with OSAHS by overnight polysomnography and all received oral appliance (OA) as the therapy.The OA positioned the mandible at 60％-70％ of the maximal mandible advancement position and created a 4-5 mm incisor separation.The patients were instructed to wear the appliance during sleep,6-8 hours per day,for 5-7 days per week.They were divided into four groups by the period of treatment,including less than 1 year group;1-2 years group;2-6 years group and 6-9 years group.The polysomnographic study was used to investigate the efficacy of the four groups.The outcome measures included the score on the apnea-hypopnea index (AHI),the longest apnea time and the lowest oxygen saturation (LSaO2) levels during an overnight sleep.Results:The AHI decreased significantly in all the four groups.The less than 1 year group decreased from 24.50 (14.65,54.05) to 7.40 (2.12,10.00) events/h (P ＜ 0.001);The 1-2 years group decreased from 19.50 (12.15,39.23) to 1.80 (0.70,6.58) events/h (P =0.001);The 2-6 years group decreased from 25.00 (11.41,42.60) to 4.50 (1.35,7.90) events/h (P =0.001);The 6-9 years group decreased from 26.2 (16.95,47.45) to 4.00 (1.90,26.70) events/h (P =0.043).The longest apnea decreased significantly in less than 1 year group,1-2 years group and 2-6 years group.The longest apnea decreased from 57.00 (37.70,61.50) to 25.00 (15.90,33.50)seconds (P＜0.001) in the less than 1 year group,from 41.00 (25.50,62.26) to 13.10 (0.00,22.10) seconds (P =0.001) in the 1-2 year group and from 42.50 (30.35,58.15) to 15.60 (0.00,28.10) seconds (P =0.003) in the 2-6 year group.The LSaO2 levels increased significantly in the less than 1 year group and 2-6 years group.The LSaO2 levels rose significantly in the less than 1 year group,from 74.18％ ±7.96％ to 84.06％ ±7.67％ (P =0.001),and in the 2-6 years group,from 76.71％ ± 10.98％ to 84.06％ ±4.64％ (P =0.006),The LSaO2 levels did not increase significantly in the 1-2 years and 6-9 years groups.Kruskal-Wallis test showed that there were no statistically significant differences in the AHI,longest apnea time and LSaO2 in 4 the groups.Conclusion:The oral appliance is an effective therapy for patients with OSAHS in the long-term treatment.However,it's recommended to make appointments with patients as a follow-up supervision whether there is any efficacy decrease.And the oral appliance should be replaced if necessary.
