Objective To identify the role of the IKK / NF-kappa B signaling pathways in the acquisition and consolidation of extinction memory in conditioning fear.Methods Aduh SD rats were treated with nuclei buried surgery.After a week recovery from nuclei buried surgery,adult SD rats accepted auditory fear conditioning training.Before the extinction training,bilateral intra-BLA infusion of sulfasalazine(SSZ),an inhibitor of IKK/NFκ B,and Vehicle were done.The freezing time were tested on the 24h and 1w after the extinction.Results After training,all the rats showed higher percentage of freezing time than the baseline(Vehicle:pre-CS 21.16％,post-CS 71.23％,P＜0.01 ; SSZ:pre-CS 22.23％,post-CS 72.14％,P＜0.01).The percentage of freezing time had no significant difference(SSZ 47.52％,Vehicle 46.20％,P＞0.05)between Vehicle and SSZ at the end of extinction training.However,SSZ groups showed significantly higher percentage of freezing time than the control group on the 24h(Vehicle 41.03％,SSZ 60.51％,P＜0.01) and the same was found on 1 weck test(Vehicle 34.17％,SSZ 57.21％,P＜ 0.01).The rats injection with SSZ showed significant fear response for the auditory fear condition.Conclusion All above results suggest that interference of IKK/NF-κ B signaling pathway impaire the consolida tion but have no effect on the acquisition of fear extinction memory in conditioning fear.The available date could provide us some clinical guidance in the treatment of post-traumatic stress disorder and panic disorder.

Objective To compare the clinical efficacy and safety of continuous subcutaneous insulin infusion (CSII) and multiple subcutaneous insulin injection (MSII) in elderly patients with severe type 2 diabetes.Methods Thirty-seven elderly patients with severe type 2 diabetes in the hospital intensive care unit (ICU) were divided into observation group (19 cases) and control group (18 cases) by random number table method.The observation group was treated with continuous subcutaneous insulin recombinant human insulin lispro injection,and control group was treated with recombinant human insulin lispro injection before meals and at bedtime routine insulin glargine subcutaneous injection.Two groups of patients and their families were given diabetes education.Changes in blood glucose,insulin dosage,blood glucose control standard time,rate of hypoglycemia and hospitalization time between 2 groups before and after treatment were compared.Results After treatment,fasting blood glucose in observation group was (7.2 ± 1.2) mmol/L,2 hour postprandial blood glucose was (9.4 ± 1.2) mmol/L,bedtime blood glucose was (9.4 ± 1.3) mmol/L; which in control group was (8.5 ± 3.0),(10.0 ± 2.4),(10.2 ± 2.4)mmol/L respectively.Fasting blood glucose,2 hour postprandial blood glucose and bedtime blood glucose significantly decreased after treatment in two groups,but there was significant difference between 2 groups (P ＜ 0.05).Blood glucose control standard time in observation group was (5.4 ± 2.5) d,insulin dosage was (43 ± 9) U/d,in control group was (12.8 ± 3.8) d,(55 ± 10) U/d respectively,and there was significant difference (P ＜ 0.05).Observation group had no hypoglycemia.Conclusion CSII for elderly patients with severe type 2 diabetes has better curative effect and security than MSII,and is more conducive to the control of blood glucose and the improvement of the condition.

Objective o observe the therapeutic effects of suspension-assisted functional rehabilitation training of motor function for patients with cerebral infarction. Methods Ninety-six patients with cerebral infarction were divided randomly into a treatment group and a control group. All patients were given routine medical treatment and routine limb movement therapy. Those in the treatment group also used an electrically-driven suspension device to aid in their functional rehabilitation training. The patients were assessed with a simplified Fugl-Meyer Motor Functional Assessment (S-FMMFA), and using the Postural Assessment Scale for stroke patients ( PASS), the Barthel Index (BI) and the 6-minute walking distance test before and after treatment and at a 6-month foliowup. Results The average S-FMMFA, PASS, BI and the 6-minute walk results in the treatment group were all significantly better than those in the control group. Conclusions Suspension-assisted training can significantly help improve limb movement function and ADL performance in cerebral infarction patients.

Nowadays, for gait instability phenomenon, many researches have been carried out at home and abroad. However, the relationship between plantar pressure and gait parameters in the process of balance adjustment is still unclear. This study describes the human body adaptive balance reaction during slip events on slippery level walk by plantar pressure and gait analysis. Ten healthy male subjects walked on a level path wearing shoes with two contrastive contaminants (dry, oil). The study collected and analyzed the change rule of spatiotemporal parameters, plantar pressure parameters, vertical ground reaction force (VGRF), etc. The results showed that the human body adaptive balance reaction during slip events on slippery level walk mainly included lighter touch at the heel strikes, tighter grip at the toe offs, a lower velocity, a shorter stride length and longer support time. These changes are used to maintain or recover body balance. These results would be able to explore new ideas and provide reference value for slip injury prevention, walking rehabilitation training design, research and development of walking assistive equipments, etc.

The levels of the antibody response against,classic swine fever (CSF) vaccine were measured by blocking ELISA at different time for pigs vaccinated with CSF vaccine (CSFV group,n= 3),pigs inoculated with porcine eircovirus type 2 (PCV2) and with CSF vaccine two weeks later (when PCV2 viremia was detected by PCR,PCV2/CSFV group,n=3),or inoculated with both CSF vaccine and PCV2 at the same time (CSFV/PCV2 group,n=3),respectively.And distribution of genome or antibodies specific to PCV2 of the PCV2 infection group,PCV2/CSFV group and CSFV/PCV2 group were also detected by indirect ELISA or PCR,respectively.The results showed that experimental infection of PCV2 was successful.In pigs inoculated with both PCV2 and CSF vaccine,the antibody response to CSF vaccine was significantly lower than that of animals treated with CSF vaccine vaccination alone at 52 days postinoculation (DPI).The average titers of antibodies against CSFV in animals of CSFV group were obviously higher than those of the PCV2/CSFV or CSFV/PCV2 group at 49 and 52DPI,respectively.The positive rate of antibodies against CSFV in pigs of CSFV group was 100% in comparison with that of animals inoculated with PCV2 and the vaccine (only 67%).The results suggested that the infection of PCV2 could suppress the antibody response to classical swine fever vaccine.
