Objective:To explore the anti-fatigue effect of Tibet maca in mice. Methods: The mice were respectively given the powder or the alcohol extract of Tibet maca. The lactic acid concentration in blood, serum lactate dehydrogenase ( LDH) , the time of weight loading swimming and serum urea ammonia level after the exercise in the mice were detected, and the anti-fatigue effect of the powder and the alcohol extract of Tibet maca was compared. Results: After the 30-day feeding, the serum LDH activity of the mice taking the powder or alcohol extract of Tibet maca was obviously higher than that of the mice in the control group(P<0. 05), the time of weight loading swimming was significantly longer than that in the control group (P<0. 05), and the blood lactic acid concentration after the exercise was obviously lower than that in the control group (P<0. 05). Conclusion: Tibet maca can improve the time of weight loading swimming of mice, and reduce the level of serum urea ammonia after exercise and blood lactic acid concentration, sug-gesting the powder and alcohol extract of Tibet maca have obvious anti-fatigue effect.

Posterior ischemic optic neuropathy is a kind of ischemic optic neuropathy, the incidence rate of which is lower with less obviously clinical features, less positive signs and more difficultly diagnosis when compared with anterior ischemic optic neuropathy.Meanwhile, therapeutic method of posterior ischemic optic neuropathy has remained controversial.This article will summarize the research development of the auxiliary examination, diagnosis, differential diagnosis and therapeutic method of posterior ischemic optic neuropathy.

Objective To investigate the effects of valsartan on the expression of acyl-coenzyme A: cholesterol acyltransferase-1(ACAT-1) and peroxisome proliferator activated receptor-gamma(PPAR-?) in atherosclerotic plaques on rabbit aortic wall.Methods Twenty-four male Japanese white rabbits were randomly assigned into three groups(8 each): control group,valsartan group and high cholesterol feeding group.All rabbits were fed according to the experimental protocol for 12 weeks.Blood samples were taken from vein for measurement of serum lipids.The ratio of intima/media thickness of the aorta was measured.ACAT-1 mRNA/protein and PPAR-? mRNA/protein were determined by reverse transcription polymerase chain reaction(RT-PCR) and Western blotting,respectively.Results After 12 weeks,the levels of serum total cholesterol(TC),triglyeride(TG) and low density lipoprotein-cholesterol(LDL-C) in valsartan group and cholesterol group were significantly higher than those in control group(P0.05).The intima thickness and the ratio of intima/media in carotid arteries in cholesterol group were significantly higher than those in control group and valsartan group(P

Translational medicine is a totally new concept which could basically eliminate the barrier between basic medicine and clinical medicine and shorten the process of‘bench to bedside’Throughout the history of the diagnosis and treatment of acute pancreatitis,we found that changes of treatment concept at each historical stage were the results of‘translational medicine’under the technical and cognitive condition at that time.This paper elaborated on the important role of translational medicine based on the diagnosing and treating development of acute pancreatitis as well as discussed the medical teaching and research under the mode of translational medicine.

Objective To construct rat calcineurin catalytic subunit ?(CnA)/enhanced green fluorescent protein EGFP gene coexpression plasmid for exploring the effect of calcineurin on the myocardium apoptosis induced by ischemia-reperfusion.Methods Total RNA was isolated from the heart of the adult Wistar rat,and CnA CDS segment of approximate 1 590 bp size was amplified by reverse transcription PCR method.CnA cDNA segment was cloned into pMD18-T Simple vector for sequencing,and the right clone was named T-CnA.CnA cDNA segment excised from plasmid T-CnA was ligated with pShuttle2 which had inserted IRES-EGFP segment into before.The DNA of the recombinant plasmid was extracted and was identified by double digesting with Nhe Ⅰ and Not Ⅰ.The right clone was named pShuttle2-CnA-IRES-EGFP.Results Sequencing result verified that the PCR product of CnA gene was identical to GenBank(NM_017041).1% agarose electrophoresis showed the bands of recombinant plasmid pShuttle2-CnA-IRES-EGFP digested by Nhe Ⅰ and Not Ⅰ were in the right range corresponding with expectation(1 590 bp and 5 240 bp).Conclusion Recombinant eukaryotic expression plasmid carrying rat CnA cDNA as well as a report gene-EGFP gene is successfully constructed in this experiment.

Objective To explore the effects of physical training on serum activity of some peripheral inflammatory markers associated with endothelial dysfunction, such as granulocyte macrophage-colony stimulating factor (GM-CSF), macrophage chemoattractant protein-1 (MCP-1), soluble intercellular adhesion molecule-1(sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in patients with chronic heart failure. Methods Forty-eight patients were enrolled and randomly divided into two groups: a training group and a rest group. The patients of both groups were both given conventional internal medicine therapy, and the patients of the training group were given physical training in addition. The serum levels of GM-CSF, MCP-1, sICAM-1 and sVCAM-1 in patients of the two groups were determined with stable chronic heart failure before and after 12 weeks of programmed physical training. At the same time, the motor functional status of chronic heart failure patients was evaluated by using the 6-minute walking test. Results It was shown that the physical training produced a significant reduction in serum GM-CSF, MCP-1, sICAM-1 and sVCAM-1 as well as a significant improvement in performance of the 6-minute walking test. Conclusion The physical training could significantly alleviate the inflammation reaction and improve the motor function of patients with chronic heart failure.

Objective To discuss the establishment and application of PACS of our hospital, and its significance for the digitization of the radiology department. Methods PACS was adopted to store and transmission of images by CR, CT, MRI, DSA. The radiologist used PACS workstation to perform post-processing of the images. Results With PACS, filmless viewing, improved diagnosis quality, accelerated generation of diagnosis report could all be implemented. Conclusion With the application of PACS to digital and filmless imaging, the patient service by the hospital can be highly improved.

The digitallization of field medical equipment for the modern troop is an important sign on military logistics modernization.The use of CR technology on the existing field X-ray equipment for digitallization upgrading can be combined with CR and PASC system,which is an effective channel on achieving digitalization of our military field X-ray image system.So the design plan of field CR and micro-PACS system combination is advanced.
