Objective To explore the effect of surgical treatment of low back pain patients with Modic change or high intensity zone(HIZ) on MRI of the lumbar spine .Methods 32 cases with intervertebral disc herniation underwent posterior lumbar inter-body fusion and 17 cases with lumbar discogenic pain underwent radiofrequency ablation from March 2011 to July 2012 were retro-spectively reviewed .For intervertebral disc herniation patients ,all patients were divided into two groups :groupⅠ (no with Modic changes group)and groupⅡ(with Modic changes group) ,according to the Admission MRI .GroupⅡ was sub-divided intoⅡa(Mod-ic type Ⅰgroup) andⅡb(Modic type Ⅱgroup) .For lumbar discogenic pain patients ,all patients were divided into group A (without HIZ group) and group B(with HIZ group) .The VAS and ODI scales at the preoperative and follow-up were recorded and analyzed . Results The postoperative scores of VAS and ODI of all the patients were improved ,and the difference was statistically significant (P<0 .05) .For intervertebral disc herniation patients ,three groups have no statistically significant difference (P>0 .05) .For lum-bar discogenic pain patients ,the improvement rate of VAS (low backpain) of A was better than that of B ,and the difference was sta-tistically significant(P<0 .05) ,but the differences of VAS (leg pain) and ODI scores weren′t statistically significant (P>0 .05) . Conclusion Posterior lumbar interbody fusion is effective for lumbar disc herniation patients with Modic changes ,and can obtain good clinical effect .For lumbar discogenic pain patients with high intensity zone on MRI ,radiofrequency ablation can cause clinical symptoms get some relief ,but the effect is poor .

This Paper reports the histochemical changes occcured at the early acute cardial ischemic area in-duced experimentally by ligation of left coronary artery of 50 male Wistar rats. The following histo-chemical changes at the ischemical areas were observed: obvious decrease of glycogen of cardical is-chemical for 1h, of both NADHD and LDH activity of ischemical for 2h as well as CCo,CK and ATP activity of ischemical for 4h. The decrease of CCo,CK and ATP activity propagated to the whole is-chemical area at the time of ischemical for 8h. The activity of NADHD,LDH'CK and ATP can toler-ated the postmortem autolysis influence up to 24h after death.

Medicine is related to people's wellbeing,which is an eternal topic that all mankind concern.Studying on the process from the origin to the development of medicine can figure out the development rules of medicine,gain experience from it,and provide guidance for better development of medicine in the future.Medical anthropology is a new discipline which focuses on the study of disease and culture.From this special perspective,studying on the process from the origin to the development of medicine can help us to have a profound and comprehensive understanding of medicine.This paper reviewed the relevant concepts of medical anthropology and the research status and research characteristics of the origin and development of Chinese and Western Medicine,providing a reference for the colleagues.

There is still evident gap between the humanity education of medical college in China and the foreign country's.We can find the heart of the matter and explore ways of solving the problem,by comparing the present condition of the humanity education of medical college in China and the foreign country's.

ObjectiveTo analyze the relative influential factors of hearing rehabilitation of the deafened children with multichannel cochlear implant. Methods42 prelingually deafened children who accepted multichannel cochlear implant were evaluated with their hearing ability, hearing thresholds and talent level, while their family and usage of the multichannel cochlear were investigated. Results and ConclusionThe result shows that the factors influencing the hearing rehabilitation are the occupations of the parents, income of the family, the time between diagnosing deaf and the operation, the time after the cochlear implant operation and the talent level. The results of the logistic regression show that the deafened children can gain their hearing developing rapidly if they living in a family with high income, their mothers have accepted more education, and they accepted longer time of continuing hearing-aid, etc.

Objective To study the expressions of heat shock protein 27(HSP27)in brain tissue and the changes of antibody of HSP27 in serum after transient cerebral ischemic reperfusion in gerbils.Methods A cerebral ischemia-reperfusion model in gerbils was established by clamping both common carotids.Sixty gerbils were randomly divided into normal control group,sham operation group and ischemia-reperfusion(IR)group.The expressions of HSP27 in brain tissue were detected by immunohistochemistry technique and the changes of antibody of HSP27 were detected by ELISA technique at the 6th hour,1st day,3rd and 7th day after IR.Experimental results were analyzed with the statistic soft package of Spss11.5.Results Experimental results revealed that HSP27 were expressed in neurons and gliacytes of the brain tissue in the 60 gerbils.There was mild expressions of HSP27 in neurons and gliacytes in normal control group and sham operation group, but it has no significant difference between the two groups(P＞0.05).Compared with normal control group,the expressions of HSP27 in neurong and gliacytes of ischemia-reperfusion gerbils were evidently increased at the 6th hour,1st day,3rd day and 7th day,especially at the 3rd day(P＜0.01).Conclusions Expressions of HSP27 in neurons and gliacytes of gerbils were increased markedly.This suggested that the increased expressions of HSP27 could protect the brain tissue from damage.The changes of antibody in serum of normal control group,sham operation group were evidently less than that in group IR,which suggest the HSP27 antibody may damage our body.

MicroRNAs(miRNA)are a kind of small non -conding RNA,which negative regulate target genes expression at post -transcription level by binding 3'-untraslation region(3'UTR).Dysregulation of miRNA pro-files relate to cancer,immune disorders,cardiovascular disease,neurodegenerative diseases and metabolic diseases. miR -221 /222 are two similary miRNAs,which share the same promoter and have the same seed sequence.miR -221 /222 usually target to same target genes and co -regulate same processes and act as onco -miRNA roles.Howev-er,miR -221 /222 maybe act as suppressor in cancer which maybe dependent particular context.The roles of miR -221 /222 are reviewed in this article,will provide a comprehensive vision for comprehending the biological process of miR -221 /222 in carcinoma.

OBJECTIVE:To establish a method for the contents determination of 4 amino acids in Pyrrosia lingua. METHODS:The samples were analyzed by RP-HPLC. It was performed on a column of Welchrom C18 with the mobile phase A of 0.1 mol/L So-dium acetate buffer(pH6.5)- acetonitrile(93∶7,V/V)and mobile phase B of acetonitrile-water(4∶1,V/V)(gradient elution)at the flow rate of 1.0 ml/min,detection wavelength was 254 nm,column temperature was 30 ℃ and the sample size was 5 μl. RE-SULTS:The linear range was 4.92-49.2 μg/ml for glutamate(r=0.999 1),3.168-31.68 μg/ml for glycine(r=0.999 9),2.6-26 μg/ml for alanine(r=0.999 4)and 2.88-28.8 μg/ml for leucine(r=0.999 9);RSDs of precision,stability and reproducibility tests were no more than 2.2%;average recoveries were 98.4%(RSD=2.2%,n=9),99.6%(RSD=2.5%,n=9),98.3%(RSD=2.2%,n=9)and 100.1%(RSD=2.3%,n=9),respectively. CONCLUSIONS:The method is simple,accurate and reproducible,and can be used for the contents determination of 4 amino acids in P. lingua.
