ABSTRACT
Objective:To explore the effect of combining repetitive transcranial magnetic stimulation (rTMS) with treadmill training in treating spinal cord injury (SCI).Methods:Fifty female Sprague-Dawley rats were randomly divided into a sham-operation (C) group, an SCI group, a treadmill training (TT) group, a treadmill training followed by rTMS (TR) group and an rTMS followed by treadmill training (RT) group. The C group only underwent laminectomy without spinal cord injury, while the model of T9 incomplete spinal cord injury was established in the other groups using the Louisville Injury System Apparatus impactor. One week after the operation the TT began. The TR group received rTMS immediately after the treadmill training and the RT group received it before. The treadmill′s speed started at 3.6m/min and gradually increased to 6m/min within 1 week. There was one 15min session a day, 5 days a week, for 8 weeks in total. The rTMS intensity was 30% of the maximum output intensity at 10Hz in 5s bursts with an interval of 25s. It lasted 10min, for a total of 1000 pulses. Hind limb motor functioning was evaluated using the Basso, Beattie & Bresnahan (BBB) locomotor rating scale and a grid walking test. The H max/M max ratio was used to quantify the excitability of the motor neurons. Immunohistochemistry was employed to detect the expression of 5-hydroxytryptamine (5-HT), 5-hydroxytryptamine 1A receptor (5-HT 1AR) and 5-hydroxytryptamine 2A receptor (5-HT 2AR). Results:The average BBB scores of the RT group were significantly higher than the SCI group′s averages from the 7th to 9th week after the injury. At the ninth week the average BBB score of the RT group was significantly higher than the TT group′s average. At the eighth and ninth week the average BBB scores of the TR group were significantly higher than in the SCI group. The number of drops in the RT group was significantly lower than in the SCI group at the seventh and ninth week. At the ninth week, the number of drops of the TR group was significantly lower compared with the SCI group. The H max/M max ratio of the SCI group was significantly higher than in the C and TR groups at the fifth and ninth week, while that of the TR group was significantly lower than the SCI group′s ratio at the ninth week. The expression of 5-HT, 5-HT 1AR and 5-HT 2AR in the RT and TR groups was significantly higher than in the SCI group, and the relative 5-HT 1AR density of the RT and TR groups was significantly higher than in the SCI and TT groups. Compared with the other 4 groups, the expression of 5-HT 2AR in the SCI group had increased significantly. Conclusions:Combining rTMS with treadmill training can significantly promote the recovery of locomotor function after incomplete spinal cord injury.
ABSTRACT
Objective To investigate the correlation of lacune of presumed vascular origin and microalbu-minuria in elderly inpatients. Methods 237 elderly patients (184 males and 53 females) at Guangzhou First People's Hospitalwho aged from 70 to 94 years old with a median age of 83.92 ± 5.32 were included in this study. We collected data on age,gender,medical history,smoking history,renal function test,blood lipid test,C-reactive protein,microalbuminuria,cerebral MR. Logistic regression was conducted to analyze all the data. Based on the MR findings ,the patients were divided into two groups:a group with lacune of presumed vascular origin (132 patients)and a control group(105 patients). Results The group with lacune of presumed vascular origin had higher mean systolic blood pressure than the control group. Median MAU was higher in the groupwith lacune of presumed vascular origin.Single factor or multiple factors logistic regression showed that increased systolic blood pressure and positive rates of MAU and MAU were independent risk factors for lacune of presumed vascular origin and were also significantly associated with the severity of lacune of presumed vascular origin. Conclusion Microalbuminuria is significantly associated with lacune of presumed vascular origin in elderly patients.
ABSTRACT
Objective The purpose of this study was to investigate the chemical constituents of Pierre. Methods The chemical compositions were isolated by silica gel column chromatography, semi-preparative HPLC,Sephadex LH-20, and MPLC packed with MCI gel, and their structures were identified on the basis of chemical and spectroscopic evidence (NMR and MS) . Results Eight compounds were obtained and determined as fibraurin (1),makisterone A (2),cycloartenol (3),feruloylphenethylamine (4),trans- -feruloyltyramine(5),β-sitosterol(6),1-monopalmitin(7),1-sinapoyl-β-D-glucopyranoside(8). Conclusion Compounds 2-8 were isolated from this plant for the first time.
ABSTRACT
Objective To Summarize experiences in the treatment of serious injury of pancreas using damage control laparotomy. Methods Retrospectively analyze the choice of surgical method and follow-up treatments on 38 patients cured by DCL,who were in serious injury of pancreas. Results 12 cases(32%) were stanched, surgical debrided and drainage quickly,6 cases(16%) were treated with improved Cogbill operation,and 20 cases(S3% ) were treated with pancreateduodenectomy without reconstruction of enteron. After recovery in SICU, all patients were treated with deterministic operation again. Totally 4 cases(11%) died,with no relation with surgical operation,and 34 cases (89%) were cured. Pancreatic fistula occurred in 4 patients(11% ) ,all of which have been cured with conservative treatment. Conclusion Patients with serious injury of pancreas in accordance with DCL, should choose proper method and take fractionated operation,based on different places and extent of the injury of pancreas.
