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 .

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.

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.

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.

Objective To evaluate three dimensional digital subtraction angiography (3D DSA) in endovascular treatment of carotid stenosis. Methods In 138 patient with ischemic stroke, the shape and stenosis of carotid artery, the feasibility of endovascular treatment and the choice of the stent were analyzed by 2D DSA and 3D DSA. Results Comparing with 2D DSA,3D DSA could clearly depict the carotid artery in shape and stenosis with correct figuring of the feasibility for endovascular treatment and choice of the stent. Conclusions 3D DSA shows the major importance in endovascular treatment of carotid stenosis providing more valuable informations than 2D DSA.

Objective To investigate the effect of hypertonic sodium chloride hydroxyethyl 40 injection (HSH)on craniocerebral injury accompanied with hypovolemic shock and ICP.Method Sixty patients suffering from craniecerebral injury accompanied with the hypovolemic shock and admitted to ICU and Neurosurgical Department of Guang dong General Hospital from September 2007 to June 2008,were chosen into the study prospectively.Those who was younger than 18years or older than 70 years,and those who were pregnant or meustruous women,or serious hepatic and renal insufficiency,hypertension,coronaxy artery disease,diabets mellitue,uncontrolled bleeding,brain death,erc were excluded.The patients were randomly divided into 3 groups.Each group included 20 patients and they were resuscitated with LR(500 ml),HIS(4 ml/kg)and HSH(4 ml/kg)respectively.The changos of blood pressure,laboratory examination indices and ICP Were detected before and at 30,60,120 minutes after resuscitation.Results MAP raised over 60 mmHg and ICP declined 10%within 30 min in HIS and HSH groups.The effect of HSH on the improving of blood pressure and the reduction of ICP wag more obvious than that of LR and HIS at 120 minutes(F=18.43,8.99,P<0.05)after resuscitation.There were no obvious oboes of the laboratory examination indices after resuscitation.Conclusions The themputic effect of HSH on ICP and MAP in craniocerebral injury accompanied with hypovolemic shock is obvious and lasting,which would be beneficial to the protection of cerebral function.

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.

Objective To investigate the carotid plaque conditions and clinical commonly used test events in patients with type 2 diabetes mellitus (T2DM) and to explore the risk factors affecting the stability of plaques in carotid artery.Methods According to the results of cervical vascular color Doppler ultrasound examination, 125 patients with type 2 diabetes mellitus were divided into unstable plaque group (n=21), stable plaque group (n =54), and non-plaque group (n =50).Analysis related results including age, gender, systolic blood pressure (SBP), diastolic blood pressure (DBP), intima-media thickness (IMT), fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), uric acid (UA), fibrinogen (Fbg), D-dimer (D-D), free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) were analyzed.Results Age, gender, SBP, DBP, TG, HDL, D-D, and TSH were without significant differences among groups.Glucose and Fbg were significant different (P ＜ 0.05) between unstable plague group and stable plaque group/no plaque group.No significance difference was found between stable and no plaque groups.IMT, TC, LDL, and FT4 were significant different (P ＜ 0.05) between unstable and stable plaque groups, and between stable and no plaque groups.Logistic multiple regression analysis suggested that IMT and TC might be independent risk factors for the stability of plaques in carotid artery of patients with type 2 diabetes mellitus (P ＜ 0.05).Conclusions The factors affecting formation of plaques in carotid artery include glucose level, TC, and LDL in patients with type 2 diabetes mellitus.The factors affecting its stability include thickness of IMT, TC, LDL, and FT4.IMT and TC were the independent risk factors for the stability of plaques in carotid artery.
