Translational medicine is a new term recently which aims to eliminate the barrier between preclinical and clinical medicine,to efficiendy and effectively translate basic scientific findings into drugs and medical devices that benefits patients.This article discussed the meaning of translational medicine in cultivating postgraduates of neurology.According to the preliminary attempt,it is beneficial for postgraduates to form translational medicine philosophy and be high-quality medical talents.

Multimedia teaching was not often used in pediatric surgery teaching in department of pediatrics.We used multimedia courseware to assist teaching in clinical teaching for 2007 grade seven-year-program students in Chongqing medical university.Results showed that this method improved students' learning enthusiasm,initiative and interests and laid a good foundation for the smooth development of their clinical practice.

Endocannabinoid system has several kinds of receptors, all of which have correspondence ligands and pathways of synthesis and degradation, and they belong to G-protein coupled receptors family. Recently studies show that stimulation of cannabinoid receptors has inhibitory effects on gastrointestinal motility and secretion. In this article, we introduce the compositions of the cannabinoid family members, includingtheir receptors, ligands, and antagonists, and their effects on the gastrointestinal motility and secretion. Useful information can be provided for the further study on the effects of endocannabinoid system on gastrointestinal motility and secretion, providing theoretic evidences for clinical use of cannabinoid.

Objective To evaluate the effect of hyperuricemia on vascular complications of type 2 diabetes and analysis of the possible mechanism. Methods 586 cases with T2DM were divided into two groups: normal serum uric acid (n=397) and hyperuricemia (n=189).The morbidity of macrovascular and microvascular complications and the serum levels of CRP,TNF,IL-1,IL-2,IL-6,IL-8 and PAI-1 were detected. Results (1)Hyperuricemia group showed higher BMI, blood pressure, TG,TC,LDL,WHR ratio and lower serum HDL-C than the group with normal uric acid (all P<0.05).(2)Group with hyperuricemia showed higher morbidities of macrovascular and microvascular complications than the group with normal uric acid (all P<0.05).(3) Group with hyperuricemia had higher levels of CRP,TNF,IL-6,IL-8,PAI-1 (all P<0.05). Conclusions (1) Hyperuricemia is associated with obesity and dyslipidemia.(2) Hyperuricemia may cause atherosclerosis by inflammation of vascular endothelium, resulting macrovascular and microvascular complications.

Objective Identifying the factors of psychological pressure from medical disputes on clinical doctors and possible solutions. Methods Self-rating Anxiety Scale (SAS) and the Occupational Stress Indicator (OSI) were called into play, to study 52 clinical doctors in a tertiary hospital in a city, who had encountered medical disputes in recent two years. In parallel, 63 clinical doctors without such disputes and 50 non-clinical workers were randomly selected as the control group for questionnaires. Results Clinical doctors with such an experience were commonly found to be anxious, and their SAS score (58. 27±11.38)averaged higher than those in the control group. Doctor-patient relationship, legal liabilities and clinical positions were found to be positively correlated to psychological pressure of clinical doctors. Conclusions Medical disputes tend to add to psychological pressure of the doctors. Clinical doctors deserve psychological counseling and training and improvement of their working conditions.

Objective To examine the expression levels of α1-adrenergie receptor(α1-AR)and angiotensinⅡ reeeptor(ATR)subtypes in left ventricle of rats from adolescent age, middle age,presenium to senium. Methods Semiquantitative reverse transcription polymerase chain reaction (RT-PCR) was used to quantitate the messenger RNA (mRNA) of α1-AR and ATR subtypes in left ventricle in Wistar rats aged 3-months (adolescent age), 12-months (middle age), 18-months (presenium) and 24-months (senium). Results The expression of α1A-AR mRNA was decreased gradually with aging, and the gene expression of α1 D-AR was repressed in middle age and presenium,while the expression of a,B-AR mRNA remained unchanged during senescence. Cardiac AT1R expression was not affected by aging from adolescent age to presenium, but exhibited a remarkable up-regulation in senium There was no significant discrepancies of cardiac AT2R expression among the four different age groups. Conclusions The results suggest that there are considerable changes in mRNA levels of cardiac α1-AR and ATR subtypes with aging. The change of cardiac α1-AR and ATR expression during aging is a protective response for senescence and has an important significance in maintaining normal physiological functions of heart.

Subcortical ischemic vascular dementia is a subtype of vascular cognitive impairment. Its major pathological features are lacunar infarcts and deep white matter changes, and its major clinical manifestation is executive function impairment. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) provides an opportunity for the study of pure subcorticai ischemic vascular dementia in the absence of Alzheimer's disease. There is currently lack of the gold standard for diagnosing subcortical ischemic vascular dementia. Imaging examination plays an important role in its diagnosis, while the treatment must first consider the control of vascular risk factors, especially hypertension.

DNA, as the material basis of all living cells, triggers innate immune responses through TLR9 and other cytosolic recognition receptors. In recent years, the research progress of TLR9 is mainly manifested by the following four aspects: (1) the determinants of TLR9 interacting with its ligands; (2) the mechanisms and the importance of TLR9 translocation from the endoplasmic reticulum to the endosome; (3) the roles of the endosomal acidification and maturation, and subsequent TLR9 cleavage in TLR9 signal transduction pathway; and (4) the possible mechanisms by which the organism distinguish self DNA from microbial DNA. Meanwhile, a series of experiments on TLR9 antagonists and TLR9 deficient mice confirmed the presence of TLR9-independent cytosolic DNA sensors. So far, three TLR9-independent DNA sensors have been found, and they are DAI, AIM2, and RNA polymerase Ⅲ.

OBJECTIVETo compare the efficacy differences between needle-knife therapy and acupuncture-cupping for treatment of cervical spondylosis (CS) of cervical type.

METHODSSixty cases of CS were randomly divided into a needle-knife group (30 cases) and an acupuncture-cupping group (30 cases). The needle-knife therapy was applied at points among superior nuchal line of occipital bone, bilateral neck muscle, neck centerline, trapezius and medial border scapula for only once. In the acupuncture-cupping group, acupuncture was applied at Fengchi (GB 20), Fengfu (GV 16), Tianzhu (BL 10), Dazhui (GV 14), Jianjing (GB 21), Jiaji (Ex-B2, from C4 to C6), Houxi (SI 3) and Ashi point, followed by cupping on local skin, once every other day for totally six times. The score of neck stiffness and visual analogue scale (VAS) were observed before and after treatment, in follow-up of 1, 3 and 6 months after treatment in the two groups, and the efficacy was compared.

RESULTSIn the needle-knife group, 9 cases were cured, 12 cases were markedly effective, 8 cases were effective and 1 case was failed; the total effective rate was 96.7% (29/30) and the cured and markedly effective rate was 70.0% (21/30). In the acupuncture-cupping group, 8 cases were cured, 9 cases were markedly effective, 11 cases were effective and 2 cases were failed; the total effective rate was 93.3% (28/30) and the cured and markedly effective rate was 56.7% (17/30). The difference of total effective rate in the two groups was not statistically significant (P > 0.05), but the cured and markedly effective rate of needle-knife group was significantly superior to that of acupuncture-cupping group (P < 0.05). The needle-knife therapy was significantly superior to acupuncture-cupping on improvement of neck stiffness in the follow-up of 1, 3, 6 months after treatment (P < 0.05, P < 0.001); both treatments were effective on relief of neck pain, but the needle-knife group had better effects in the follow-up of 3 and 6 months after treatment compared with acupuncture-cupping group (both P < 0.01).

CONCLUSIONThe needle-knife therapy has better effects on neck stiffness and pain relief than acupuncture-cupping, and it is more treatment time saving.
