The conception of evidence-based medicine (EMB) has a strong influence on the medical world since it built up.This concept has been widely used in all sorts of clinic and basic medical research,however,it is little reported to be practised in our fundamental medical education.As for it,this article will briefly analyze the importance of introducing the idea into fundamental medical education,and for one thing,suggest some more reform measures for medical teaching staff.

Medicare work runs throughout the whole process of military training and directly affects the quality of military training. Good preparation,medical service and preventive health care work were done to reduce the injury rate during military training from recognizing significances ,char-acteristics,rules and methods of medicare. Additional health-related military programs,targeted tech-nical and tactical training and optimization and integration of teachers are effective ways to expand the military direction,improve and enrich the content o military training.

Objective To investigate the effects of goal‐directed volume therapy (GDVT )on the intracranial pressure(ICP) and the balance of cerebral oxygen consumption and supply in selective neurosurgery. Methods Twenty‐four patients sched‐uled for intracranial tumor resection were randomly divided into 2 groups:conventional fluid management group (group C ,n=12) and GDVT group(group G ,n=12). Patients in group C received introperative fluid transfusion according to classical fluid management strategies while those in group G received GDT according to stroke volume variation (SVV) ,guided by Flotrac‐Vigileo system.Mean arterial pressure(MAP) ,heart rate(HR) ,cardiac index(CI) ,ICP ,SVV and jugular bulb oxygen saturation (SjvO2 )were recorded before the anesthesia induction(T1 ) ,at the moment of intubation(T2 ) ,at the moment of opening the hard meninges(T3),1hafteropeningthehardmeninges(T4),andattheendofthesurgery(T5).Thecerebraloxygenextractionra‐tio(CERO2 )was calculated. The duration of surgery ,crystalloid volume ,colloid volume ,blood transfusion volume ,urinary output and bleeding volume were recorded as well.Results The colloid transfusion volume ,the total fluid transfusion volume and uri‐nary output were significantly increased in group G when compared with those in group C (P<0.05).MAP ,CI ,and SjvO2 were much higher and CERO2 were much lower at T4 and T5 in group G than in group C(P<0.05). There was no significant differ‐ence in the ICP at each time point between groups G and C (P>0.05).Conclusion Goal‐directed fluid therapy optimizes the cardiac preload without increasing the ICP in selective neurosurgery ,and it also improves the balance of cerebral oxygen con‐sumption and supply.

Apelin is a polypeptide consisting of 77 amino acids. Apelin receptors are found to be the angiotensin-like G protein coupled receptor (APJ). Apelin/APJ system is widely distributed in the peripheral and central nervous system. Apelin-13 is one of the subtypes of Apelin, which has strong biological activity. This study reviewed the new research prog?ress of Apelin-13 on physiological and pathological processes involved in the cardiovascular system, respiratory system, ner?vous system, digestive system and endocrine system.

BACKGROUND: Recent studies have shown that TCM massage can alleviate or even reverse the progression of muscle fibrosis, so it is speculated that massage can also improve the pathological changes of gluteal muscle contracture. OBJECTIVE: To evaluate the role of massage on gluteal muscle contracture and the relevant mechanism. METHODS: Twenty young rabbits were divided into an experimental group and a control group, with penicillin and benzyl alcohol injection for 8 weeks respectively. Besides, the experimental group received massage therapies for 4 weeks, whereas the control group had no specific intervention. Cell morphology and structure were observed using hematoxylin and eosin staining, Masson staining and Sirius red staining. Expression of transforming growth factor-pi in the rabbit model of gluteal muscle contraction was measured using immunohistochemistry, reverse transcription PCR and western blot assays. The study protocol was approved by the Ethics Committee of Peking University Shenzhen Hospital in China. RESULTS AND CONCLUSION: The experimental group had significantly less hyperplasia of fiber tissue compared with the control group (F < 0.05). The expression levels of collagen type I and transforming growth factor-31 were significantly increased in the control group compared with the experimental group, as determined by reverse transcription PCR, western blot assay and immunohistochemical staining (P < 0.05). Therefore, massage therapy can alleviate the progression of gluteal fibrosis, which is expected to provide a new idea for the research and treatment of gluteal muscle contracture.

Acidolysis kinetics on the process of the hydrolysis acidification by using glucose as the only energy sources was researched.It was concluded that the acidolysis kinetics constants are V_(max)=8.45d~(-1) and K_s=1089mg/L,under the circumstances of a temperature 37℃?0.5℃and the influent pH value 6.5.The results show that the rate of anaerobic acidification process is greater than that of completed an- aerobic or anoxic process.

Objective To analyze the laboratory detection findings in infectious mononucleosis(IM) and mucocutaneous lymphnode syndrome(MCLS)and find the main points of the differential diagnosis and direct the treatment. Methods Five hundreds and twenty-five children were in-patient department over these past 10 years .These patients were divided into 2 groups,IM group (225 patients) and MCLS group(280 patients). EB-virus antibody,Paul-Bunnell test,the circumference blood numeration ,classification of leucocytes,the numeration of atypical lymphocytes were detected and compared,as well as blood platelet of these patients.Results The positive rate of EB-virus antibody in IM and MCLS were high, and had no discrepancy. However, the positive rate of Paul-Bunnell test and numeration of atypical lymphocyte in IM group were significantly higher than those in MCLS group. The total circumference blood leucocyte numeration of the groups increased,but the numeration neutrophil increased significantly in MCLS group, the rising numeration of lymphocyte in IM; the blood platelet numeration was elevated significantly in MCLS group and continued when the total circumference blood leucocyte numeration tended normally.Conclusions The causes of IM and MCLS are related to the infection of EB-virus. The laboratory characteristics of IM and MCLS are different,understanding the main points of the differential diagnosis contributes to the clear diagnose and early treatment.

BACKGROUND:A novel galactosylated alginate-chitosan oligomer microcapsule has been prepared successful y. There is no report on hepatocytes encapsulated into the microcapsule prepared with chitosan oligomer and alginate sodium.
OBJECTIVE:To study the structure and properties of the previous novel galactosylated alginate-chitosan oligomer microcapsule, and then explore the morphology and function expression of the hepatocytes encapsulated.
METHODS:The membrane structure and thickness of the microcapsule (containing 50%or 30%galactosylated alginate) were observed using a laser confocal microscopy. Mechanical property was determined by mechanical rupture rate. Permeability was evaluated by release profile of fluoresceine isothiocyanate-labeled human serum albumin and immunoglobulin G. The morphology of hepatocytes in the microcapsule was observed using an inverted phase contrast microscopy. Function expression of the hepatocytes included albumin secretion and urea synthesis.
RESULTS AND CONCLUSION:The microcapsule had an asymmetry structure, with dense inner and loosened outer surfaces. With the increase of the galactosylated alginate, the membrane became loose, which indicated the negative charge on the alginate molecular chains was weakened after introduction of galactose, and thus electrostatic complex was affected. Mechanical property was correlated with both membrane structure and thickness. With the increase of the galactosylated alginate, the membrane structure became loose and the thickness was decreased, resulting in poor mechanical properties. The permeability was dependent mainly on the pore size of the skin layer of the membrane other than the loose sublayer. The prepared microcapsule can selectively pass through the human serum albumin and cut off immunoglobulin G, indicating skin pore size between human serum albumin and immunoglobulin G. The hepatocytes can form sphere assemble in the galactosylated alginate-chitosan oligomer microcapsule and exhibit improved albumin secretion and urea synthesis compared to the control in the alginate-chitosan oligomer microcapsule.
