Objective To observe age-dependent feature of damage of hippocampus to different maturational stages rats after kindling repeated seizures.Methods The effects of 5 daily pentylenetetrazol-induced convulsions in different rats beginning at postnatal day 10,20,60(P10,P20,P60)were evaluated.In the 3 groups,Thionin staining method was utilized to observe morphological changes and cell counting of dentate granule cells,CA3,CA1,and hilar neurons.Timm's method of silver sulfide staining was adopted to observe the mossy fiber sprouting.Results 1.Cell counting of CA1,CA3 and hilar neurons in P10 and P20 groups demonstrated no differences from controls in rats,whereas P60 with daily seizures had a significant decrease in CA1,CA3 neurons(8.22?1.88,5.62?1.68 vs 6.31?1.50,3.62?1.40)(t=2.246,2.587 Pa

Objective To evaluate the stability and biodistribution of a novel SPECT-MRI bi-functional agem 99Tcm-Gd-DTPA-DG in tumor-bearing nude mice. Methods DTPA-DG was synthesized and then conjugated with Gd2O3 to generate Gd-DTPA-DG. The tumor-bearing nude mice were scanned by MRI to evaluate the tumor targeting ability of Gd-DTPA-DG. The orthogonal experiment was applied to optimize pH value of reaction medium and reaction temperature. The radiolabeling efficiency was measured by thin layer chromatography. The distribution of 99Tcm-Gd-DTPA-DG in nude mice was evaluated by scintigrapy in vivo. The % ID/g was measured at different time after intravenous injection of 99Tcm-Gd-DTPA-DG. Results The tumor was significantly enhanced by Gd-DTPA-DG with MRI. The radiochemical purity of 99Tcm-Gd-DTPADG was about 98.5% and remained 96.2% at room temperature for 6 h. The tumor was well visualized by 99TcmGd-DTPA-DG SPECT at 2 h after injection. The tumor uptake was (1.48 ±0.12) %ID/g, and the rumor to muscle radioactivity ratio was 2.91. Conclusions MRI contrast of Gd-DTPA-DG may enhance tumor detection. 99Tcm-labeled Gd-DTPA-DG may be useful for tumor imaging and might have a potential role as a SPECT-MRI bi-functional agent.

AlM: To investigate the association between the degree of anterioruveitis and related factors including inflammatory markers as well as sacroiliac joint imaging in patients with ankylosing spondylitis ( AS) .
METHODS: Anterior changes evaluated by slit lamp, erythrocyte sedimentation rate ( ESR ) , C - reactive protein ( CRP ) and magnetic resonance imaging of 55 cases with AS associateduveitis were retrospectively analyzed. A modified endotoxin-induced uveitis ( ElU ) clinical standard was used for uveitis grading. SPARCC sacroiliac scoring was used to evaluate bone edema of sacroiliac joint. The correlation between the degree of uveitis and sacroiliitis was assessed.
RESULTS: ln the 55 patients with AS, ElU grading scored 2-10, and SPARCC index scored 0-22. Further analysis showed that the severity of uveitis was significantly correlated with ESR (r=0. 869, P<0. 001) and CRP (r=0. 485, P<0. 001). The degree of anterior uveitis in AS patients was not correlated with inflammation of sacroiliac joint (r=0. 237, P=0. 081).
CONCLUSlON: Local autoimmunity of uveitis and sacroiliac joint inflammation with subsequent bone formation in AS might be mutually independent processes.

Objective To study the effects of vitamin B_6(VitB_6) injection on small intestinal peristalsis in mice and its mechanisms.Methods The mice were divided into 12 groups:calcium chloride injection group(1 mg/10 g),neostigmine methylsulfate injection group(0.001 5 mg/10 g),atropine sulfate injection group(0.005 mg/10 g),their combination with VitB_6 injection and high/low dose treated groups,high dose VitB_6 injection group(5 mg/10 g),low dose VitB_6 injection group(0.5 mg/10 g) and physiologic saline group(0.1 mL/ 10 g ).After administration 30 minutes,mice were intragastric administration Indian ink(0.1 mL/g),and they were luxated and put to death 20 minutes later.The mice belly were cut open,the length of intestine and distance of Indian ink that had moved were measured,and then the ink progradation rate were calculated.Results Compared with control group,the high dose VitB_6 injection could inhibit normal intestinal peristalsis of mice markedly(P0.05).Conclusions VitB_6 injection can inhibit hyperanakinesia of small intestine in mice,especially high dose.And this will be provided as theory foundation on enterospasm treatment.

Objective To observe the long term effects of arthroscopic knee debridement and reconstructing operation for treating osteoarthritis in patients with Kaschin-Beck disease. Methods Thirty-one cases of patients with Kaschin-Beck disease were followed for 6 years after operation of articular clearing by arthroscope. Index of pain, symptoms of self-evaluation, range of motion, walking distance, standing test by affected leg when bending at 30° or 60° were recorded and compared with the preoperative results. Results Twenty-four cases were followed up for 6 years. Six years after operation the pain index(3.38 ± 2.87) was dramatically decreased compared to that before operation (6.88 ± 1.45, t = 5.30, P ＜ 0.05). Patients symptoms markedly improved by subjective self-evaluation was 70.83% (17/24), the effective rate was 100% (24/24). The number of cases that could stand up when leg bending at 30° or 60° were 21,18 cases, respectively, compared with that of preoperative of 14, 11 cases, respectively, the difference was statistically significant(x2 = 5.17,4.27, all P ＜ 0.05). Six years after operation the walking distance(3 cases ＜ 1 km, 11 cases 1 - 5 km and 10 cases ＞ 5 km) were greatly improved compared to the results before operation (12 cases ＜ 1 km, 9 cases 1 - 5 km and 3 cases ＞ 5 km, U = 2.88, P ＜0.05). Six years after operation the knee activity[(132.25 ± 14.52)°] remained at the same level, compared with that of preoperative [(131 .58 ± 14.68) °], the difference was not statistically significant (t = 0.16, P ＞ 0.05) .Conclusions The method of arthroscopic joint debridement to cure Kaschin-Beck disease knee osteoarthritis can significantly reduce pain, improve function and walking distance, with more stable long-term satisfactory outcome.

Objective To compare the effects of high and low frequencies of repetitive transcranial magnetic stimulation (rTMS) on rehabilitation of motor function in patients with cerebral infarction. Methods From October 2010 to June 2011,60 patients with cerebral infarction undergoing treatment in our department were randomly assigned into 3 even groups. In addition to conventional medication and functional training for all patients,group A were given high frequency (3 Hz) rTMS once per day and 10 minutes per time for 14 days,group B low frequency (1 Hz) rTMS and group C sham stimulation in the same manner. The 3 groups were compared before and after stimulation in terms of motor function scores of Fugl-Meyer assessment (FMA),the Barthel index (BI),motion evoked potential (MEP) and central motion conduction time (CMCT). Results Before stimulation,there were no significant differences between the 3 groups in FMA,BI,MEP and CMCT (P ＞0.05),but significant significances were observed between the 3 groups after stimulation (P＜0.05) indicating that the motor functional recovery in groups A and B was significantly better than in group C. But there were no statistically significant differences between group A and group B in FMA,BI,MEP and CMCT (P＞0.05).Significant improvements were achieved in all 3 groups after rehabilitative treatment in FMA,BI,MEP and CMCT (P＜0.05). Conclusion Both high frequency rTMS and low frequency rTMS can promote motor functional recovery for patients with cerebral infarction, and their effects are not significantly different.
