Objective To examine the circulating glucose and body weight in the transgenic MKR mouse model who expressed dominant-negative IGF-1 receptor and insulin receptor in skeletal muscle leading to systemic insulin resistance and diabetes. Methods MKR mice were genotyped by PCR analysis of tail DNA.And in these mice we examined the circulating glucose and body weight once a week from 1 to 16 weeks of age, and the circulating insulin and glucose tolerance at age of two-month-old by using C57 mice as controls. Results The descendents of MKR mice kept hereditary feature. And these mice had hyperglycaemia from 3 weeks of age,and an increasing body weight slowly(P

Objective To investigate the effect of tuftsin and its inhibitor on pancreas microcirculation in acute pancreatitis(AP). Methods Sprague Dawley (SD) rats were randomly divided into five groups. Murine AP model was produced by retrograde injection of 4% sodium taurocholate into pancreatic duct, tuftsin or its inhibitor was injected at a dosage of 75 ?g/kg. At the time of 0,3, 6, 12 h, pancreas was harvested for pathology of microthrombus. esults Microthrombus in control group was not different with that in tuftsin group; At the time of 3、6 and 12 h microthrombus in other 3 groups significantly increased than control group and tuftsin group; With time, microthrombus in AP group、AP+ tuftsin group and AP+inhibitor group increased steadily and statistically significant; Tuftsin inhibitor significantly decreased microthrombus at the time of 6、12 h.Conclusions In acute pancreatitis tuftsin deteriorated pancreas microcirculation, which could be partially reversed by the administration of tuftsin inhibitor.

OBJECTIVETo explore the curative effect and safety of acupuncture for mild cognitive disorders after stroke.

METHODSRandomized controlled trial was adopted and one hundred cases conforming to criteria were divided into a combined acupuncture and medication group (group A) and a medication group (group B), 50 cases in each group. The basic treatment of cerebrovascular disease was applied in two groups. The group A treated was with acupuncture at Baihui (GV 20), Shenting (GV 24) and Qucha (BL 4) etc. and oral administration of Nimodipine. In group B, Nimodipine was taken orally. The treatment lasted for 3 months, the scores of Mini-Mental State Examination (MMSE), modified Hasegawa Dementia Scale (HDS-R) and Barthel Index (BI) were observed before and after treatment in two groups.

RESULTSThe total effective rate in group A was 66.7% (32/48), which was superior to 30.4% (14/46) in group B (P < 0.05). The scores of MMSE, HDS-R and BI after treatment were apparently improved as compared with those before treatment in two groups (all P < 0.01). The improvements in group A were superior to those in group B (all P < 0.05). There was no adverse event reported during the treatment in two groups.

CONCLUSIONAcupuncture can improve activity of daily living and has significant effect in treating mild cognition disorders after stroke without adverse reactions.

BACKGROUND: Ultrasound-medium frequency electrotherapy has better pain-relieving effect,whether it involves enkephalin and the like neurotransmitter is still not very clear, it is necessary to carry out qualitative and quantitative analysis of the pain response in rats received ultrasound-medium frequency electrotherapy.OBJECTIVE: To investigate the pain-relieving effect of ultrasound-medium frequency electrotherapy and its influence on the enkephalin content in rats, aiming to probe its underlying mechanism and relationship with neurotransmitter enkephalin.DESIGN: Randomly controlled study taking experimental animals as subjects.SETTING: Department of Physiotherapy, First Hospital Affiliated to China Medical University, Institute of Basic Medicine, Peking Union Medical CollegeMATERIALS: This experiment was carried out at the Institute of Basic Medicine, Peking Union Medical College between June 2002 and March 2003. Forty healthy male Wistar rats were adopted and randomized into four groups,namely methionine enkephalin detection experimental group and control group,as well as leucine enkephalin detection experimental group and control group with 10 rats in each group ,amongst which methionine enkephalin experimental group and leucine enkephalin experimental group were generally designed as experimental group ,with the other two group as control group.METHODS: ①Rats ín the experímental group were subjected to ultrasound-medium frequency electrotherapy with frequency of 0.8 MHz in manner of geminal pulse,the modulatìng frequency was 100 Hz and ultrasound intensity of 0.9 W/cm2;the carrier frequency of medium frequency electricity was 4 kHz with modulating frequency of 100 Hz in manner of continuous wave,the electric current of medium frequency was 2 mA and acting time of 10 min. rats in control group received the same dealing,but the higher voltage of ultrasound-medium frequency electrotheprauetic instrument was not used, thereby no energy output was available. tail flick test(TFr) was used to test rat algesthesia,and stopwatch was used to record the time for tail flick(s) that was taken as the value of pain threshold. ②The threshold of pain was tested at 10 minutes instantly after ultrasoundmedium frequency electric stimulation,and then pituitary (removing the posterior pituitary lobe) and hypothalamus were obtained to detect the content of methionine enkephalin and leucine enkephalin by using radioimmuno assay.MAIN OUTCOME MEASURES: The changes of the pain threshold after treatment,the content of methionine enkephalin and leucine enkephalin.RESULTS: Totally 40 rats were enrolled in the experiment and entered in the results analysis. ① The changing rate of pain threshold in two experimental group were 265.79% and 272.90% respectively,the difference was of no statistical significance (P ＞ 0.05). ②After ultrasoundmedium frequency electrotherapy,the content of methionine enkephalin and leucine enkephalin in pituitary and hypothalamus were obviously higher than before treatment [ The changing rate of methionine enkephalin and leucine enkephalin in adenohypophysis was 300.48 ±36.21)% and(204.61±68.65)% , respectively, compared to (239.80±59.98)%and(205.53±51.62)% in hypothalamus, P ＜ 0.05]. ③Linear regression analysis revealed that the variance of the pain threshold was positively correlated with the content of methionine enkephalin in adenohypophysis(r=0.91 ,P ＜ 0.01), suggesting the increment of methionine enkephalin in adenohypophysis was closely connected with the increment of pain threshold,and the level of methionine enkephalin in adenohypophysis would be higher than that in control group by 117.02% when the value of pain threshold increased by100%.CONCLUSION: One of the important mechanisms for the pain-relieving effect of ultrasound-medium frequency electrotherapy might be the increase of methionine enkephalin in adenohypophysis.

Objective To study the average difference of CHN atlas method bone age (BA) determination (left-vs.right-hand) for children and adolescents.Methods Radiographs of hands of healthy children and adolescent (age range:1.0-19.0 years) were analysed to determine BA,producing analysis results for 1380 hand images.The images were assessed by two radiologists based on CHN atlas method,who were blinded to the chronological age (CA) of them.The intra-and inter-observer variations were used for evaluating the reliability of CHN atlas method.The difference of BA using left-or right-hand BA was evaluated by t test.Results No significant difference was found for intra-or inter-observer variations (P ＞ 0.05).The BAs of left-and right-hand radiograph showed significant difference in the groups for boys (16.0-16.9,17.0-17.9 years),girls (6.0-6.9 years) and both of them (6.0-6.9,16.0-16.9 years).The regression model analysis showed no significant difference(t =-0.427,P =0.670).Conclusion Comparison of left-and right-hand BA shos no significant difference using CHN atlas method,indicating that either hand could be used to determine BA.
