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 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 .

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.

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.

From the view of medical professionals, this paper explored the standards of residents′ competency cultivation in Zhuhai using Delphi method. The research outcome that consisted of 53 factors and 6 dimensions was obtained after two rounds of expert consultation. There are 6 first-level indexes including professionnalism and body-mind quality, clinical practice skill, the competency of lifelong learning and self-improvement, humanistic medicine practice skill, medical knowledge, and the competency of promoting the medical system to develop. As well, there are 18 second-level indexes and 29 third-level indexes. The standards stated that the clinical prac-tice skill would not be the main part of residents′competency cultivation. Qualified residents should reach the na-tional standard of the clinical practice skill but also the other five indexes.

Objective To evaluate the use of three-dimensional (3D) digital subtraction angiography (DSA) in endovascular treatment of carotid stenosis.Methods In 216 patient of ischemic stroke,carotid artery shape,stenosis,the feasibility of endovascular treatment and the choosing of the stent were analyzed at 2D DSA and 3D DSA. Results Comparing with 2D DSA,3D DSA can clearly depicted the carotid artery shape and stenosis.3D DSA can correctly judge the feasibility of endovascular treatment,can correctly choose the stent.Conclusions 3D DSA is very important in endovascular treatment of carotid stenosis.It can provide many valuable information for endovascular treatmen that 2D DSA can not provide.

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 compare the purity and extraction rate of four purecollagen type I products prepared from various biomaterials by a limited enzyme digestion method for the use in tissue engineering.[Method]Bovine cortical bone, bovine achilles tendon, porcine achilles tendon and porcine skin were splitted into pieces of 0.2-0.5 mm. After being immersed in glacial acetic acid, they were extracted with pepsin. Then the crude products were dissolved, centrifuged, dialyzed and freeze drying to prepare pure collagen type I. The final products were confirmed by absorbance, amino acid analysis and'SDS-PAGE electrophoresis comparing them with the products of Sigma Company.[Result]The wave length of maximum absorbance of the final products was 230 nm, and the amino acid analysis and SDS-PAGE electrophoresis confirmed that the final products were collagen type I. The purity of product extracted from bovine cortical bone was the highest (96.12%) and higher than that from Sigma Company. The extraction rate of bovine achilles tendon collagen was the highest (75.34%).[Conclusion]Collagen type I of higher purity and higher extraction rate can be prepared using a limited enzyme digestion method.And the product from bovine cortical bone is better than the others,which has a promising prospect.
