Objective: To investigate the prevalence and clinical significance of Modic changes in endplates of cervical vertebral body in patients with cervical spondylotic myelopathy(CSM). Methods: The T1-weight and T2-weight sagittal MRI scans of 136 CSM patients undergoing anterior operation were retrospectively reviewed. The patients' age, gender, prevalence, precise vertebral levels and specific type of Modic changes were recorded, and the association of axial pain with Modic changes was analyzed. Results: Modic changes were observed in 23 patients (16.9%), including 17(17.7%) male and 6(15%) female. The most frequent cervical spinal levels of Modic changes was C5-6. Of all the patients, 4.4% had type I Modic change, 7.4% had type II, and 5.1% had type III. The incidence of axial pain was 56.5% in Modic change groups and 20.4% in non-Modic change groups; there was significant difference between the two groups (P<0.05). Postoperatively, the axial pain was relieved in 76.9% in Modic change groups and 73.9% in non-Modic change groups (P>0.05). The pre-operation incidences of axial pain in patients with type I, type II and type III Modic change were 83.3%, 60% and 28.6%, respectively; and the post-operation pain-relieving rates were 100%, 66.7% and 50%, respectively. Conclusion: The most common Modic change is type II in the cervical spine, with the C5-6 level being the most frequently involved. The incidence of axial pain is high in patients with Modic change, especially those with type I.

Objective To investigate the effect of Bax and Bcl-X_L expression in newborn rat with moderate hyperoxic exposure. Methods Hyperoxic lung injury model was established by exposure to 60% O_2 in the neonatal period of SD rats. Rats exposed to air were used as control groups, with 8 animals in each group on repeated experiments. The pathology of pulmonary tissues was detected by HE stain. Mean alveolar area and alveolar number per ?m~2 were applied to estimate the pathological effects of prolonged hyperoxia in neonatal rats. The expression of Bax and Bcl-X_L proteins in lung were detected by immunohistochemistry and the expressions of Bax and Bcl-X_L mRNA by RT-PCR. Results In hyperoxia groups, alveolar dysplasia appeared 4 days after hyperoxia, mean alveolar area increased and alveolar number per ?m~2 decreased from the 4th day. Bax and Bcl-X_L protein were mainly expressed on bronchiolar epithelial cells and vascular endothelial cells. Compared with control group, the expression of Bax increased from the 1st day after hyperoxia, Bax mRNA decreased from the 11th day (q=8.4802, P

Objective To examine the effect of endotoxin on myocardial lipid metabolism and determine it′s possible mechanism Methods Sixty nine male Wistar rats (350 450g) were randomly divided into 2 groups: in vivo group and in vitro group In in vivo group endotoxin 0 1?g?kg -1 (small dose)or 1mg?kg -1 (large dose) was injected intrabdominally 3h after endotoxin administration the animals were anesthetized Heart was excised and passively perfused in a Laugendorff apparatus with oxygenated Krebs Heuseleit buffer at 37℃ Non esterified fatty acids (NEFA)and triacylglycerols(TAG) were used as energy supplying substance when the isolated heart had been stabilized for 15min NEFA or TAG was slowly added to the perfusate circuit 1 ml of perfusate was drawn every 10 min until the end of experiment (80 min ) for determination of the effects of endotoxin on NEFA or TAG oxidation and utilization by isolated heart At the end of experiment heart was harvested and frozen for measurement of myocardial lipids and lipoprotein lipase activity In in vitro group endotoxin was added to perfusate (1mg/ml) after the heart was excised and passively perfused In control group endotoxin was replaced by normal saline Results Large dose of endotoxin administered in vivo decreased NEFA oxidation rate by 30% in perfused isolated heart and caused increased accumulation of lipid in myocardial tissue By contrast endotoxin administered in vitro increased oxidation rate of TAG accompanied by an increase in myocardial lipoprotein lipase activity Administration of endotoxin in vivo and in vitro also caused accumulation of various exogenous lipids in myocardium in both NEFA and TAG perfused heart Conclusions This study shows that endotoxin has a significant effect on myocardial lipid metabolism The effect of endotoxin could be either direct or indirect according to the different lipids available

Objective To explore the utility of videofluoroscopy in observing swallowing dysfunction after severe traumatic brain injury (TBI). Methods Videoflouroscopic studies of swallowing (VFSSs) were performed on 40 patients with severe TBI as well as 40 healthy matched controls.Information about penetration and aspiration was collected,and oral delay time (ODT),oral transit time (OTT),pharyngeal delay time (PDT),pharyngeal transit time (PTT) and the maximum vertical and anterior movement of hyoid bone were measured. Results Seventeen of the healthy controls (42.5％) displayed mild penetration,though none had severe penetration or aspiration.Among the severe TBI patients,5 ( 12.5％ ) displayed mild penetration,12 (30.0％) showed severe penetration and 17 (42.5％) subjects had aspiration.The 3ml liquid swallowing parameters of the severe TBI group were ODT ( 0.86 ± 0.37) s,OTT (0.73 ± 0.28 ) s,PDT ( 0.50 ± 0.35 ) s and PTT(0.61 ± 0.11 ) s.The maximum vertical hyoid bone movement in this group averaged (0.98 ± 0.38) cm,and maximum anterior movement was (0.37 ±0.37) cm.The healthy controls and severe TBI patients showed significant differences in terms of all six measures.Conclusion Dysphagia was found to be frequent among severe TBI patients,commonly occurring in the oral and pharyngeal phases.Videoflouroscopy may be helpful for identifying the main features of dysphagia and formulating better rehabilitation strategies.

Objective To explore the reparative effect of bactericidal/permeability-increasing protein(BPI) on the damaged mucosa of rats with otitis media with effusion (OME),and state the pathogenesis of OME.Methods Wistar rats(40 ears) were randomly divided into six groups:normal control group (n=4),BPI control group(n=4),eustachian tube obstruction (ETO) group (n=8),lipopolysaccharide (LPS) injection group (n=8),ETO+LPS group (n=8),ETO+LPS+BPI group (n=8).The experimental OME model was made through eustachian tube obstruction and LPS injection.The rats were killed after 1,2 and 4 weeks and the changes of mucosa of middle ear were observed under light and scanning electron microscope.Results The rats in normal control group and BPI control group had the normal mucosa in the tympanic orifice of the eustachian tube.It consisted of pseudostratified ciliated cubical or columnar epithelium which contained an abundant number of ciliated cells and a few goblet cells,these were the mucociliary clearance system of the middle ear.The hypotympanum consisted of thin,squamous epithelium with few microvillus.Middle ear mucosa was obviouly thickened in LPS injection,ETO and ETO+LPS groups.An increase in goblet cells and a decrease in ciliated cells were observed in the tympanic orifice of the eustachian tube.The epithelial layer in the hypotympanum had become more pseudostratified ciliated cubical epithelium.In ETO+LPS+BPI group,there was thin squamous epithelium in the hypotympanum near normal,which was not thickened and contained few microvillus. Conclusion LPS and ETO can result in the occurrence and protracted courses of OME by mimosa's inflammatory reaction which can reduce the activity of ciliary cells and weaken the function of mucociliary clearance system.BPI could bind avidly to LPS,reduce inflammatory reaction,and break the inflammatory cycle and reestablish an effective mucocillary clearance system.The results suggest that BPI treatment is a potential effective drug for prevention and therapy of chronic OME.

Objective The national essential medicine select system is the core of Chinese medicine policy.How to select drugs fundamental for eyes scientifically is an important ring in establishing the Chinese essential drug system.The present study attempted to compare the National Essential Medicines List and National Essential Insurance List of China with that of the WHO in order to provide reasonable evidence for the adjustment of a new National Essential Medicines List of China. MethodsThe WHO Essential Medicine List (15th edition,Version in 2007),National Essential Medicine List (Version in 2009,China),2009 National Essential Medicine List Chemical Medicine Name (Version in 2009) and National Essential Insurance List of China (Version in 2004) were reviewed.The similarity and difference in the category and number of drugs in the National Essential Medicines List and National Essential Insurance List between China and WHO were compared and analyzed.A descriptive method was adopted to analyze the sorts and numbers of eye drugs in the lists mentioned above.The analysis of drug price was based on the summary sheet from Zhejiang Province. ResultsLittle difference was found in the numbers of eye drugs between the National Essential Medicines List of China and WHO Essential Medicines List.Differences in the sorts of eye drugs were observed in the lists,especially between the National Essential Medicines List of China and WHO Essential Medicines List.Except for levofloxacin,all of the drugs in the National Essential Medicine List of China were included in the National Essential Insurance List of China.ConclusionThe selecting principle and renewing procedure of the National Essential Medicines List and National Essential Insurance List of China should be further improved in China based on the list from WHO.More attention should be paid to the standard,dosage form,affordability,maneuverability etc.during the selecting procedure of eye essential drugs.
