1.Effects of interleukin-1βon MMP-13 expression in rat chondrocytes and its regulation of miR-27b
Tianjin Medical Journal 2015;(8):871-875
Objective To observe the effect of interleukin-1β(IL-1β) on expression of Matrix Metalloproteinases 13 (MMP-13) in rat chondrocytes and its regulation of miR-27b. Methods Chondrocytes were extracted from 7 Wistar male rats. Expression of MMP-13 were examined by Western blot at 0 h, 24 h, 48 h after IL-1βstimulation. Differential miRNAs expression profiles were examined by miRNAs microarray. The most obviously down-regulated miRNAs were confirmed by quantitative Real-time PCR. Targeted regulation relationship between miR-27b and MMP-13 was set up by Luciferase re?porter gene experiments. Results Expression of MMP-13 in rat chondrocytes was increased at a timely dependent manner upon IL-1βstimulation(P<0.05);Microarray revealed 36 miRNAs whose expression changed, among which 6(miR-27b, miR-31, miR-26a, miR-26b, miR-23, miR-204)were especially obvious. Real-time PCR confirmed that miR-27b was the one whose expression level were most down-regulated. Transient co-transfection of miR-27b mimics with luciferase expres?sion plasmids resulted in significant repression of luciferase activity in rat chondrocytes (P < 0.05). Conclusion IL-1βstimulation result in down-regulation of miR-27b and up-regulation of MMP-13 expression. MiR-27b and MMP-13 show targeted regulation relationship.

[Objective]To compare two preparing procedures for larger chemically acellular nerve allografts (CANA). [Methods]The sciatic nerves of pigs were exposed by a muscle-splitting incision and were isolated free of the underlying fascia. The 60-mm-long segments of the nerve were obtained. They were treated according to the following decellularization processes.In group I,the nerve segments were treated with 7% Triton-100 solution and 7% sodium deoxycholate for two times.In group II,another protocol was created with the detergents Triton X-200,sulfobetaine-16,and sulfobetaine-10 for two times. The degrees of decellularization,activity of laminin,degrees of demyelination,and integrity of the nerve fiber tube were observed under microscope and were assessed by a scoring system.[Results]In both experimental groups the activity of laminin was present and the degrees of decellularization were complete. As for the demyelization of the nerve segments,the myelin sheath in Group II was partially preserved,but it completely disappeared in Group Ⅰ. The structure of the nerve fiber tube in Groups Ⅰ and Ⅱ were not as integral as that in the normal group.[Conclusion]It may be a better method for the larger CANA,to be treated with TritonX-100 and sodium deoxycholate during the decellularization procedure.

在地震中,颅脑外伤极为常见,其救治过程特点为:发生突然、时间急、伤员多、伤情复杂、抢救难度大。治疗细节决定救治的成败。在早期治疗中,主要是维持生命体征,为原发性脑损伤提供恢复条件,避免继发性脑损伤。尽早转运到后方专科医院治疗,减少死亡及伤残率。

Objectives To find out the effects of estrogen and clomiphene on behavior of epileptic rats induced by kainic acid (KA) and probe into some mechanisms. Methods Ovariectomized Sprague-Dawley female rats were treated with estrogen (E) or estrogen and clomiphene (C). Their behaviors when they were induced seizures were observed and compared. Indirect immunofluorescence method was used to measure the alterations of gamma-aminobutyric acid (GABA) immunoreactive cells and ?1 subunits of GABA_A receptors in the hippocampus of all groups. Results The latency and time at reaching 4/5 degrees in KA+E group ((24.63?11.44) minutes and (41.50?16.22) minutes, respectively) were reduced greatly than KA group ((46.75?14.61) minutes and (65.13?12.99) minutes), while the latency of (KA+)E+C group (adding estrogen and clomiphene, (43.50?5.75) minutes) became prolonged significantly than in KA+E group. Conclusion High-level estrogen should be proconvulsant and the clomiphene might have some antiepileptic effects, which may be related with some alterations of GABA energic function in the brain.

[Objective]To investigate the curative effect and methods of distal tibial fracture by operation.[Method]From May 2004 to Feb.2005,30 cases of distal tibial fracture were treated in the department.All cases were treated with open reduction,internal fixation with medial anatomic plates,and with bone-grafting prophylacticly in all cases.The operation would be done on 10~14 days after fracture.They were followed up and analyzed retrospectively.[Result]All cases were followed up for 8~17 months(average 13.9 months).All wounds were primary healing and all fractures obtained bone-union.Twenty-two cases were the excellent,6 cases were the good according to Mazur's criteria.The excellent and good rate was 93.3%.All cases had no severe complication,such as wound infection,cutaneous necrosis and bone non-union.[Conclusion]Anatomic plate of distal tibia is a perfect choice for treatment of distal tibial fracture.Operative juncture and prophylactic bone grafting were very important to obtain satisfactory effect.

Objective:To evaluate the clinical efficacy of treatment of sudden deafness using hyperbaric oxygenation, and to provide guidance for its treatment. Methods:The studies about sudden deafness treated with hyperbaric oxygenation combined with drug were retrieved in Cochrane Library, PubMed , MEDLINE, Wanfang Database and CNKI up to July 2016.RavMan 5.3 provided by Cochrane was used for Meta-analysis.Results:Thirty-nine studies which were randomized controlled trials (RCTs)were included, a total of 4 599 cases,of which 2 418 cases received hyperbaric oxygenation therapy combined with drug treatment as treatment group and 2 181 cases received drug treatment alone as control group.A total of 36 studies about the comparison of clinical efficacy between treatment group and control group were included in the Meta-analysis, the result showed that treatment group had a significant clinical efficacy than control group(RR:1.26,95%CI:1.22-1.30,P<0.0001).A total of 6 studies about the improvement of the pure tone average(PTA)in the two groups were included in the Meta-analysis, the PTA gain was significant better in hyperbaric oxygenation group(WMD:11.8,95%CI:4.77-18.83,P<0.000 1).A total of 11 studies about the stage of using hyperbaric oxygenation therapy were included in the Meta-analysis, the result suggested that the early use of hyperbaric oxygenation therapy had better effect than the late use of hyperbaric oxygenation (RR:1.42,95%CI:1.31-1.53,P<0.000 01).Conclusion:The clinical efficacy of hyperbaric oxygenation combined with drug therapy is better than drug therapy alone, the PTA gain is significantly improved and the introduction of hyperbaric oxygenation therapy at the earlier stage shows better results.

Objective:To examine the discriminatory potential of the ADAS-Cog, Chinese version for mild and moderate Alzheimer's disease (AD). Methods:Patients with AD (199 mild AD and 106 moderate AD) meeting the NINCDS-ADRDA criteria of probable AD were recruited. The Chinese version of ADAS-Cog was administered to all AD subjects. Results:The total score of ADAS-Cog and the score of each ADAS-Cog item differed significant-ly between mild and moderate AD groups, with higher scores in moderate AD group. GLM analysis showed insignifi-cant influence of age or educational level on the ADAS-Cog total score. These results indicated that ADAS-Cog could represent the distinctive profiles of cognitive impairment between mild and moderate AD. The results of Logis-tic regression analysis showed that the item score of orientation and constructional praxis as well as the ADAS-Cog total score could classify mild and moderate AD efficiently, with a sensitivity of 78% - 82% and a specificity of 70% - 73%. Conclusion:Our results indicate that the Chinese version of ADAS-Cog is useful for staging of AD. It is recom-mended that the Chinese version of ADAS-Cog be introduced for monitoring the AD drug therapeutic efficacy on cognitive impairment among Chinese AD patients.psychiatry Alzheimer's disease
