Objective To investigate the changing features of microtubule associated protein 2 (MAP2) expression, which was a neural dendrite marker, of epileptic rat and the intervention results after using Diazepam. The relations between MAP2 and epileptogenesis were also explored.Methods Model of epileptic rat was established by Pentylenetetrazol (PTZ) and divided into PTZ-NA group,PTZ-Diazepam group, Diazepam-PTZ group and normal control group. Immunohistochemistry method was applied on hippocampus of epileptic rats to determine the change of MAP2 immunoreactivity (MAP2-IR) with or without Diazepam intervention at various time points. MAP2-IR was showed by mean optical density (COD).Results In the PTZ-NA group and PTZ-Diazepam group, MAP2-IR in molecular cell layer of hippocampal dentate gyrus increased after 3 days (all P

Objective To prepare and characterize the polyclonal antibody against N protein of SARS-CoV. Methods The polyclonal antibody against SARS-CoV N was obtained from immunized rabbit with purified GST-N. The titer of the antibody was determined by indirect ELISA, and the specificity by Western blot and immunochemical staining. Results The rabbit′s antibody against SARS-CoV N was prepared successfully. The titer of antiserum against SARS-CoV N was about 1.2?10~ -5 . Western blot and immunochemical staining analysis showed that the polyclonal antibody could bind to the expressed fusion protein specifically. Conclusion The rabbit′s antibody against SARS-CoV N has been prepared successfully, and it can be a useful reagent for clinical diagnosis and further research.

Objective To construct an expression vector pGEX-2T/N, and to express the fusion protein consisting of N protein of SARS-CoV in E. coli.Methods The N region gene of SARS-CoV was obtained by RT-PCR. The expression vector PGEX-2T/N was constructed by DNA recombination. The recombinant plasmid was transformed into E. coli BL21(DE3). The expression of the fusion protein was determined by Western blot with anti-SARS-CoV antibody positive blood sera. Results The N region gene of SARS-CoV was obtained. The fusion protein GST-N was soluble. Western blot analysis showed that the reaction of GST-N to anti-SARS-CoV sera was positive. Conclusion The pGEX-2T/N has been constructed and expressed in the form of fusion protein GST-N successfully, and the result lays the foundation for further study of SARS-CoV N protein.

Background Posterior capsular opacification (PCO)affects the pseudoaccommodation of 1CU accommodative intraocular lens (1CU AIOL).At present,few studies on the effect of PCO and Nd∶ YAG laser capsulotomy on intraocular shifting of 1CU AIOL are published.Objective The present study was to evaluate the effect of PCO and Nd∶YAG laser capsulotomy on the shifting of 1CU AIOL.Methods A respective serial caseobservational study was designed.Written informed consent was obtained from each patient prior to this study.Twentyfour eyes of 20 patients with PCO after phacoemulsification and implantation of 1CU AIOL were included in this study.Ocular examination was performed 3 months after IOL implantation,1 day before Nd:YAG laser capsulotomy and 3 months after Nd∶YAG laser capsulotomy to evaluate the distance corrected near visual acuity(DCNVA).The difference in the anterior chamber depths before and after administering 1% pilocarpine topical eye drops was measured with the IOLMaster to determine the intraocular shifts of the IOL.The extent of IOL shifting was compared among 3 time points to assess the factors influencing IOL accommodation after 1CU AIOL implantation.Results The shifting amplitude of 1CU AIOL was(0.44±0.21)mm 3 months after implantation of 1CU AIOL,(0.27±0.11)mm 1 day before Nd ∶ YAG laser capsulotomy,and (0.34±0.10) mm 3 months after Nd ∶ YAG laser capsulotomy,showing a significant difference among them(F=7.180,P=0.001).The shifting amplitude of 1CU AIOL significantly declined 1 day before Nd∶YAG laser capsulotomy in comparison with 3 months after implantation of 1 CU AIOL(P =0.006).The shifting amplitude 3 months after Nd∶YAG laser capsulotomy increased slightly in comparison with 1 day before Nd∶YAG laser capsulotomy(P=0.059).DCNVA was(3.1±0.9)J 3 months after implantation of 1CU AIOL,(6.2±0.8) J 1 day before Nd ∶ YAG laser capsulotomy and(3.4±0.7) J 3 months after Nd ∶ YAG laser capsulotomy,with a significant difference among them (F =110.270,P =0.000).DCNVA was lower 1 day before Nd∶ YAG laser capsulotomy than 3 months after implantation of 1CU AIOL(P<0.05).However,DCNVA was higher 3 months after Nd∶YAG laser capsulotomy than that of 1 day before Nd∶YAG laser capsulotomy (P<0.05).There was no significant correlations between DCNVA and IOL movement 3 months after IOL implantation,1 day before Nd∶ YAG laser capsulotomy and 3 months after Nd ∶ YAG laser capsulotomy (r1 =-0.150,P1 =0.486,r2 =-0.320,P2 =0.122,r3 =-0.100,P3 =0.633).Conclusions The shifting amplitude of 1CU AIOL markedly declines due to PCO.No clinically significant influence of Nd ∶ YAG laser capsulotomy on the shifting amplitude of 1 CU AIOL is found.DCNVA can improve after Nd∶YAG laser capsulotomy.Multiple inter-related factors concerning pseudophakic accommodation may influence DCNVA.

Rheumatoid arthritis (RA) is a kind of chronic, progressive, multiple, invasive autoimmune disease with two chief cclinical manifestations arthrosynovitis and ex-arthrosis, easy to occur in middle-aged women, also occur in children and the elderly, is characterized by progressive and break out repeatedly. RA pathogenesis is complex, there is no special treatment, used in treatment of R drug varied, new drugs and new therapies also emerge in endlessly, main including non-steroidal anti-inflammatory drugs (NSAIDs), slow action anti-rheumatism medicine (SAARDs), glucocorticoids (GCs), biological agent, traditional Chinese medicine and traditional Chinese medicine preparations, domestic market for rheumatoid main drug treatment are NSAIDs, SAARDs, GCs, traditional Chinese medicine and traditional Chinese medicine preparations. Traditional Chinese medicine and traditional Chinese medi- cine preparations for the treatment of RA have its unique advantages, show the characteristics of overall adjustment, multi-level and multiple targets, and also can alleviate and against side effects of western medicine. In recent years, more and more get people's atten- tion. This paper reviewed the research progress and treatment features of commonly used therapeutic agents for the treatment of RA in recent years, which provides reference and basis for future medicine anti-RA.

BACKGROUND: The change of the axial angle of the lower limb is related to the occurrence and development of osteoarthritis.OBJECTIVE: To analyze the correlation between the change of lower limb power line and pain area in the knee osteoarthritis patients.METHODS: Totally 65 knee osteoarthritis patients were selected as pain group and 30 healthy people were selected as control group. All the participants took anteroposterior and lateral knee radiographs through PACS imaging systems to collect six imaging indexes, including install index, the degree of tibiofemoral joint subluxation, tibiofemoral inside and outside joint clearance ratio, femoral angle, tibial angle and tibiofemoral angle. Knee osteoarthritis patients in pain group were divided into two common clinical pain areas which were proparea and medial area.RESULTS AND CONCLUSION: (1) The insall index, the degree of tibiofemoral joint subluxation, tibiofemoral inside andoutside joint clearance ratio between knee osteoarthritis patients in pain group and people in healthy control group hadsignificant differences. There was no statistical significance in the femoral angle, tibial angle and tibiofemoral angle. (2) In terms of the comparison between proparea and medial area in knee osteoarthritis patients in pain group, tibiofemoral joint subluxation degree was statistically different. (3) These findings suggest that there was a higher patella in knee osteoarthritis patients who were in pain, more severe in the degree of tibiofemoral joint subluxation, and more limited in tibiofemoral inside and outside joint clearance ratio. The degree of tibiofemoral joint subluxation of proparea was more severe than medial area in pain group.
