Objective To study the effect of fetal transplants on the fu nctional recovery after spinal cord transection in new born and adult rats. Meth ods The spinal cord tissue at E14 of a rat fetal was transferred into the hemise ction cavity at lumbar spinal cord in the newborn and adult rats. 4, 8, 12 weeks after the operation, spinal cord tissue morphology, combined behavioral score ( CBS), somatosensory evoked potentials (SEP), and motor evoked potentials (MEP) w ere examined. Results The transplanted tissue survived in the host spinal cord. There was a statistical difference in CBS between the newborn graft group and th e adult graft group. The peak latencies of early waves in SEPs and MEPs of the n ewborn graft group were superior to those of the adult graft group (P

Spinal cord injury occurs with an average annual incidence of 15 40 cases per million of population. The costs of treatment and rehabilitation in the living period of patients with spinal cord injury are very high. Prevention, therapy and rehabilitation of spinal cord injury have become a major subject in medical science. The aim of this article is to summarize the statistics of incidence, etiological factors, clinical characteristics and complications in patients with spinal cord injury.

Objective To investigate the protective effect of trichostatin-A (TSA) on cerebral ischemia/reperfusion injury via Janus kinase/signal transducer and activator of transcription (JAK/STAT) signal pathway.Methods 36 male SD rats were randomly (random number) divided into 3 groups:shamoperated group,ischemia/reperfusion (I/R) group and TSA group.Rat model of middle cerebral artery occlusion/reperfusion (MCAO) was established using a modified filament method.No occlusion was applicated to the sham-operated group.TSA group was injected with TSA 0.05 mg/kg via penile vein,20 minutes before operation.Reperfusion was carried out 24 hours after modeling.Longa 5 score was used to assess the neurological function,and TTC staining was applied to calculate the percentage of cerebral infarction area,The expression of JAK2 and p-JAK2 proteins was detected by Elisa.Results The low expression of JAK2 was observed in each group,and there was no statistical difference between groups (P =0.266).Compared with I/R group,TSA group had lower score in cerebral ischemia-reperfusion injury assessment (P=0.019),smaller area of cerebral infarction (P ＜0.01),reduced expression of p-JAK2 (P =0.009),all of which were of significant difference.Condusions TSA can reduce the cerebral ischemia/reperfusion injury via JAK/STAT signal pathway by down regulating p-JAK2 expression.

Allergic rhinitis is a common disease, which was released by the IgE-mediated atopic individuals exposed to allergens in the earlier researches. However, there are variety of immunocompetent cells and cytokines involved in the nasal mucosa immunologic mechanism in nowadays researches. The mechanism of AR is caused by the imbalance of the Th1/Th2, a kind of allergic inflammation who is characterized by the nasal Th2 immune response dominant. Th1 cells mainly produce of IFN-gamma (does not include IL-4 and IL-5), Th2 cells produce IL-4, IL-5, IL-9 and IL-13 (not including IFN-gamma). Recently it was found that regulatory T cells (T regulatory cells, Treg) and Th17 cell research played a crucial role in the occurrence of allergic inflammation.

Objective: To assess the values of conventional vascular ultrasound (US) and superb micro vascular imaging (SMI) for diagnosing carotid artery stenosis in relevant patients. Methods: A total of 37 patients of extra cranial carotid stenosis (with 70 blood vessels) treated in our hospital from 2014-08 to 2015-03 were retrospectively studied. Digital subtraction angiography (DAS) examination was used as golden standard, the diagnostic efifcacies for carotid artery stenosis by US and by SMI were compared. Results: The accuracy, sensitivity and specificity for diagnosing carotid stenosis by US were 81.42%, 83.33% and 80.95%; by SMI were 91.43%, 92.16% and 89.47% respectively. Conclusion: US and SMI showed good agreement for diagnosing carotid artery stenosis, while SMI was superior to US for accurately assess the degree of carotid stenosis, it might be used as a more reliable method for evaluating carotid plaque and stenosis in relevant patients.

Objective To investigate the prevalence of sleep-disordered breathing in elderly patients with permanent cardiac pacemaker implantation due to bradyarrhythmias, and the relationship between pacing mode and patients' sleep apnea-hypopnea index.Methods Forty-four elderly patients (＞60 years) with cardiac pacemaker and their 44 controls matched for gender, age, body mass index and cardiovascular morbidity were studied using polysomnography or portable sleep monitoring device. Results Prevalence of sleep-disordered breathing (apnea-hypopnea index ≥5/h) was 44.7% and the mean apnea-hypopnea index was 8.2 ±4.1/h in the cardiac pacemaker group, which were significantly higher than those in control subjects (25% and 4.6±2.4/h, respectively, P＜0.01 and P＜0.05). The mean apnea-hypopnea index of patients with DDD or AAI pacemaker was significantly lower than that of patients with VVI pacemaker. Conclusions Sleep-disordered breathing was more common in patients who had their cardiac pacemaker implanted due to bradyarrhythmias than in their matched controls. Compared with VVI pacing, DDD or AAI pacing may be more beneficial to patients with bradyarrhythmias and sleep-disordered breathing.

Objective To evaluate the influence of integrated-CT artifacts on attenuation-corrected (AC) images of SPECT bone imaging. Methods Imaging documents of 78 patients who underwent SPECT/CT bone imaging were retrospectively analyzed, and the artifacts on CT images and CT attenuation maps were visually studied. Compared with the non-attenuation corrected (NC) images, the coefficient of variation (CV) and percentage difference (PD) of radioactive count of regional bone influenced by CT artifacts were calculated and statistically analyzed to estimate the influence of CT artifacts on AC images of SPECT bone imaging. Results The integrated-CT artifacts were found in 38 patients of 78, and appeared the same image findings as those on CT attenuation maps respectively, including truncation artifact, thoraco-abdominal gas artifact, photon starvation artifact, etc. On all the AC images with integrated-CT artifacts, regional bones were influenced not only on uniformity (CVAC 17.62%±4.13%, CVNC 11.19%±3.81%;t=2.13, P<0.05), but also by the distribution (PDAC 16.98%±3.31%, PDNC 9.84%±1.62%;t=2.46, P<0.05) of radioactive count. Conclusion Artifacts on integrated-CT images can induce false AC information on CT attenuation maps, therefore, a comparative analysis with NC images is recommended if necessary.

3), the intra-day RSD was less than 10% and the inter-day RSD was less than 12%. The average recovery stood at 86.96%. CONCLUSION: The established method is simple, rapid, precise and suitable for the determination and pharmacological study of faropenem in human plasma.

Pinellia ternata(Thunb)Breit.was one of the common herbs in clinic and pharmaceutical industry of traditional Chinese medicine.Because of being over excavated of wild Pinellia temata(Thunb)Breit.year by year,the supply was unable to meet the demand at domestic market.In order to keep the supply richly and utilization persistently,we have studied the planting of wild Pinellia ternata(Thunb)Breit.for years.This paper was focused on the reviews of technology about breeding,planting,field management,cropping,processing and store of Pinellia ternata(Thunb)Breit.
