A monolayer which is formed by a binuclear palladium complex of low rim methionine-disubstituted calix[4]arene exhibits extraordinary cohesiveness. Cohesiveness measurement and Brewster Angle Microscopy observation show that the monolayer is uniform and robust. This film is probably formed by self-assembly of precursor complex through strong chloride ion bridge between palladium centers.

Objective： To explore the features, treatment outcomes and reasons for misdiagnosis in patients with multiple trauma, so as to decrease the incidence of ***： A total of 3 163 patients with multiple trauma who were admitted in our department from August 1997 to August 2008, were retrospectively studied to compare the features of diagnosis and treatment. There were 2 117 males （66.93%） and 1 046 females （33.07%） with the mean age of 36.46 years （range, 14-80 years）. Parameters such as general status, traumatic condition, diagnosis and treatment situation, prognosis and mortality were analyzed. The differences between misdiagnosis group and correct diagnosis group were compared in terms of severity of injury, complications and treatment outcomes to elucidate the cause and prevention of ***： The misdiagnosis rate of multiple trauma in this study was 16.19%. The major anatomic sites misdiagnosed were limbs and pelvis （299 positions, 39.50%）, abdominal region and pelvic organ （148 positions, 19.55%）,and thoracic region （109 positions, 14.40%）. In misdiagnosis group, ISS, length of hospital stay, rates of disturbance of consciousness, critical cases and shock cases were 33.78± 19.64, （23.59±7.26） days, 49.22%, 33.01% and 47.46%,respectively, which were significantly higher than those of the correct diagnosis group （P〈0.01）. And the data showed that the more serious the injury was, the higher the rate of misdiagnosis would be. The rate of primary diagnosis by trauma surgeons in correct diagnosis group was 75.78%, significantly higher than that of the misdiagnosis group （ x2=382.01,P〈0.01）. The mortality rate of the mi sdiagnosis group was 2.93%, which was significantly higher than that for all patients （ x2=5.22, P〈0.05）.Conclusions： The results indicated that patients with severe multiple trauma are at high risk of misdiagnosis in early treatment. The mortality rate of misdiagnosed patients is higher than the correctly-diagnosed patients.

Background Noninvasive functional magnetic resonance imaging （fMRI） techniques have opened a ＂window＂ into the brain, allowing us to investigate the anatomical and physiological function involving acupuncture needling. Imaging its sustained effect rather than acute effect on the brain networks may further help elucidate the mechanisms by which acupuncture achieves its therapeutic effects. In this study, we aimed to investigate the functional brain networks during the post-resting state following acupuncture at KI3 in comparison with acupuncture at GB40. Methods Needling at acupoints GB40 and KI3 was performed in twelve subjects. Six minutes of scanning at rest were adopted before and after acupuncture at different acupoints. Then we divided the whole brain into 39 regions and constructed functional brain networks during the post-acupuncture resting states （PARS）. Results For direct comparisons, increased correlations during post-resting state following acupuncture at KI3 compared to resting state （RS） were primarily located between the dorsolateral prefrontal cortex （DLPFC） and post temporal cortex, ventromedial prefrontal cortex （vmPFC） and post temporal cortex. These brain regions were all cognitive-related functions. In contrast, the increased connections between the anterior insula and temporal cortex mainly emerged following acupuncture at GB40 compared with the RS. Conclusions The present study demonstrates that acupuncture at different acupoints belonging to the same anatomic segment can exert different modulatory effects on the reorganizations of post-acupuncture RS networks. The heterogeneous modulation patterns between twoconditions may relate to the functional specific modulatory effects of acupuncture.
