Aim To investigate the neurotoxicity and the changes of nitration in the striatum of rats treated with methamphetamine(MA).Methods The rats were randomly divided into MA group and control group.The stereotyped behavior and body temperature of the rats were recorded.The differences of nitric oxide, nitric oxide synthase(NOS)and nitroprotein were compared between the two groups.Results The score of stereotyped behavior and the body temperature of the rats in MA group were significantly higher than those in the control group(P ＜0.01);Compared with the control group, the content of NO and the activity of NOS of striatum in MA group were significantly increased(P ＜0.01), and nitration of protein was also upregulated(P ＜0.01).Conclusion The increases of NOS activity, NO level and nitroprotein may play an important role in MA-induced neurutoxity in rat striaturn.

Objective:To investigate the criterion-related validity of Menopause-Specific Quality of Life Questionnaire (MENQOL)-Chinese version and to evaluate the effect of menopausal symptoms on health related quality of life. Methods:This study was a cross-sectional survey. Three communities were randomly chosenin Changsha,and then 340 menopausal women aged 45-55 years were randomly chosen from the documented data of the 3 community health service centers. They were required to fill out 4 questionnaires: demographic questionnaire, MENQOL-Chinese version, Kupperman Index (KI) and World Health Organization Quality of Life (WHQOL)-BREF. Correlation analysis was used to measure the criterion-related validity. Results: MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) and KI total score were positively correlated (r=0.800,0.751, 0.607, 0.906 respectively); while negatively correlated with WHOQOL-BREF total score (r =-0.694,-0.851,-0.585,-0.873 respectively); MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) were signiifcantly correlated with WHOQOL-BREF subscales (physical, psychological, social relationship, environment), and the physical domain was the highest among the correlation coeffcients (r=-0.915). Conclusion:MENQOL-Chinese version shows relatively high criterion-related validity compared with KI and WHOQOL-BREF, which can be widely used to measure the quality of life of menopause women in China.

Objective To investigate the clinical effect of the 1 470 nm diode laser for the treatment of superficial bladder tumor.Methods Two hundreds and sixteen patients diagnosed with superficial bladder tumor were treated in our hospital from January 2012 to January 2014 and divided into the laser group and electric cutting group.The two groups were treated by 1 470 nm diode laser and transurethral plasma kinetic resection respectively.The basic data and the observation indexes were compared be tween the two groups.Results The operation time,intraoperative bleeding volume,indwelling catheter time and hospital stay time in the laser group were significantly less than those in the electric cutting group.The levels of epinephrine,norepinephrine and an giotensin Ⅱ in operation and at postoperative 6 h in the laser group were significantly lower than those in the electric cutting group (P＜0.05).The obturator nerve reflex and bladder perforation did not occur in the laser group,and the total complications occurrence rate was 5.1％,the bladder tumor recurrence rate in postoperative 24 months was 7.1％.The obturator nerve reflex occurrence rate was 7.6％,the vesical perforation rate was 1.7％,the total complications occurrence rate was 15.3％,the bladder tumor recurrence rate in postoperative 24 months was 17.8 ％ in the electric cutting group.The above indexes of the laser group were significantly lower than those of the electric cut group(P＜0.05).Conclusion The 1 470 nm diode laser for the treatment of noninvasive superficial bladder tumor has definitely curative effect,is easy to operate with low postoperative complication occurrence rate,high safety and low middle and long term recurrence rate,moreover has little influence on patient's stress level.

Objective: Dithiothreitol(DTT) and ?-Mercaptoethanol(2-ME) are important reducing agents for SDS-PAGE.This study is to observe the diffusing effect of DTT and 2-ME during electrophoresis,and to find a way of avoiding this effect.Methods: We placed protein samples containing reducing agents and non-reduced protein samples separately in the sample wells at intervals for SDS-PAGE electrophoresis,and determined whether or not the electrophoretic lanes of the non-reduced samples were interfered by the adjacent lanes.Results: DTT and 2-ME diffused to the neighboring lane,so that the non-reduced samples were reduced partially.The spreading effect was positively correlated with the content of the reducing agent.Conclusion: DTT and 2-ME have a diffusing effect during SDS-PAGE electrophoresis.In separating the reduced and non-reduced proteins in the same gel at the same time,at least a blank lane should be set up in between them in order to avoid the diffusing effect.

Objective To better understand the clinical characteristics of Familial Idiopathic Basal Ganglia Calcifi?cation (FIBGC), including at the perspective of hereditary pattern, clinical test results, onset age, clinical heterogeneity and the volume of basal ganglia calcification (VBGC). Method 8 Eight FIBGC families were collected and draw family pedigrees were draw. Analysis of was conducted on the patient's clinical test results, head CT and MRI changes, onset ag?es, relationship of clinical manifestations with VBGC. Results No significant difference was found in serum calcium, alu?minum, arsenic, cobalt, magnesium, phosphorus, iron, parathyroid hormone and calcitonin concentration between the fam?ily members of patients and healthy controls (P>0.05). Family members from 8 FIBGC families including the two with consanguineous marriage manifested autosomal dominant heredity. The severity of , symptomatic s was correlated with VBGCpatients showed the same clinical manifestations in the dyskinesia family. The psychiatric symptoms was not asso? ciated with VBGC whereas patients with dyskinesia had a large VBGC. There was a significant difference in onset age be?tween patients with psychiatric symptoms and those with dyskinesia. P.atients with dyskinesia suffer larger VBGC, and is characterized by Patients with dyskinesia had relatively later onset age (43.95 ± 2.47 y) whereas those with. psychiatric symptoms hadsymptomatic patients with early onset age (31.32±10.16y). The comparison of the onset age (43.954±2.473 vs. 31.319±10.156 y, t=4.438, P=0.001) and VBGC (1.748±0.622 vs. 0.392±0.276 cm3, t=2.518, P=0.028) with symptom?atic patients between dyskinesia and psychogenic families was significant. Conclusions Eight FIBGC families manifested autosomal dominant heredity. Patients with dyskinesia suffer have a larger VBGC and are associated with a, and is char?acterized by relatively later onset age. In contrast, patients with psychiatric symptomspsychogeny is not related withhave a the small VBGC and showedand their age of onset is young. earlier onset age.

The plants in genus Gentianella Moench (Gentianaceae) which comprised approximately 250 species, are mainly distributed in temperate regions of the world.Many Gentianella plants are intensely bitter and employed in traditional medicine to stimulate appetite, treat disorders of the gallbladder, and treat fever like the other bitter gentians in various regions of the world.Some species exhibit other remarkable therapeutic effects in the treatments of obesity,diabetes, and heart diseases.Eleven iridoids, twenty-eight xanthones, three C-glucoflavonoids, and eight other compounds have been isolated from the genus.Most of these compounds are associated with antimicrobial,anti-inflammatory, anti-oxidant, hypoglycemic, and antitumor activities, which provide an empirical base for the traditional utilization of the plants in genus Gentinella Moench.

Results The accuracy rates of localization detected by B-Ultrasound,CT scan and MRI were 84.3%,100% and 100% respectively. The accuracy rates of qualitative diagnosis by B-Ultrasound, CT scan and MRI were 30.0%,75.5% and 79.2% respectively. There were 60 cases underwent operation and the postoperative pathological examination confirmed that there were 31 cases of adrenal cortical adenoma, 6 cases adrenal cyst, 5 myelolipoma, 5 pheochromocytoma, 3 adrenal cortical carcinoma, 3 metastatic carcinoma, 3 ganglioneuroma, 1 adrenal neurilemmoma, 1 adrenal hematoma, and 1 nodular hyperplasia of adrenal cortex. Conclusions Ultrasonography is the first choice of scanning adrenal incidentaloma. However the CT scan and MRI are satisfactory in localization of the tumour. The qualitative diagnosis of adrenal incidentaloma will depend on the diameter, imaging features of tumors, the age of patients, and endocrine examination.

The one-step method was adopted in this study to synthesize aliphatic polyurethane with 4,4-methylene dicyclohexyl diisocyanate(HMDI), 1,4-butanediol (BDO) and poly (tetrahydrofuran) (PTMG). The tests conducted on this material were: FIR spectrum, mechanical properties test, water contact angles test, hemolysis test and platelet adhesion test. Results showed that this material has a good tensile strength up to 30 Mpa, similar to aromaphatic polyurethane. But its tensile elongation, tensile permanent change, hydrophility are better than those of aromaphatic polyurethane. The hemolysis test and platelet adhesion test showed that it has good blood compatibility.
