Objective To investigate pathophysiological changes in the multifidus muscles of patients with lumbar disc herniation.Methods Thirty-six patients with unilateral symptoms caused by lumbar disc herniation were enrolled.They were divided into a symptomatic side group and a contralateral side group according to whether their symptomatic (algetic) or contralateral side would be studied.The percentage area of pimelosis and the mean gross signal intensity of each multifidus were measured with magnetic resonance imaging (MRI)_ The amplitude and duration of motor unit potentials of each multifidus were recorded using electromyography (EMG) when the patients were performing isometric contraction.Results The bilateral multifidus muscles of 36 patients displayed various degrees of pimelosis on magnetic resonance images.The percentage of pimelosis cross-sectional area in the symptomatic side group was significantly higher than in the contralateral side group.[(44.20 ± 15.14)％ versus(37.31 ± 13.85)％,P ＜ 0.05] The mean value of the gross signal intensity was also significantly higher.Both the amplitudes and duration of the motor unit potentials recroded from the multifidus had increased and widened,but significantly more in the symptomatic side group than in the contralateral side group.Conclusions Both the imaging and electrophysiological data showed more significant changes on the symptomatic side in patients with unilateral symptoms caused by lumbar disc herniation.

Circulating tumor cells (CTCs) play an important role in tumor metastasis.Detections of CTCs are contribute to tumor treatment,which can provide reliable basis for predicting the prognosis and efficacy.CTCs are related to the staging and distant metastasis of non-small cell lung cancer (NSCLC).The number changes of CTCs are associated with the chemotherapy and radiotherapy effects and prognosis in NSCLC.Almost the same phenomena have been discovered in small cell lung cancer.In the future,CTCs may be used to monitor the occurrence of drug resistant tumor cells and help individual therapy for lung cancer.

As a major venue of scientific research activities,medical colleges and institutes are also an importance source of providing highly trained medical talents.With the medical education reform deepen,scientific research is now becoming the focus point of exploring the social aspect of medicine.Taking one military medical university as example,this paper demonstrated four specific measures for managing social sciences research in medical colleges.

This paper presents the situation of secrecy management at colleges and universities,and analyzes the reasons for the inadequacy of capability in this aspect.From the perspective of PAEI management roles,we point out the solutions to improve the capability include strengthening leaderships,targeting,building system,managing risks and raising awareness of secrecy.

Hilar cholangiocarcinoma is the most common types of cholangiocarcinoma,it is difficult to perform operation owing to its anatomic characterstics.Currently,radical resection is the most important prognostic factors of hilar cholangiocarcinoma.In addition,lymph node metastasis and biomarkers such as CA19-9,hepatocyte growth factor receptor,interleukin-8,and so on,are also closely related to the prognosis of hilar cholangiocarcinoma.This paper will review the relevant researches of China and abroad to summarize important prognostic factors of hilar cholangiocarcinoma above-mentioned.

Based on recent cellular architectural studies on the bed nuclei of the stria terminalis (BST) in the rat by Ju et al, we studied vasoactive intestinal polypeptidelike immunoreactivity (VIP-LI) in the BST using PAP and ABC techniques. (1) Compared with VIP-LI cells, the VIP-LI terminals were more abundant and concentrated. At the periphery of the oval nucleus and in the juxtacapsular nucleus, there was a dense accumulation of VIP-LI terminals. Less densely innervated areas were the part above the anterior commissure in the anterior lateral area and the central part of oval nucleus. The fusiform nucleus and rostral part of the anterior ventral area contained moderate amount of VIP-LI terminals. The principal nucleus, interfasicular nucleus, posterior dorsal nucleus and dorsal nucleus, were devoid of VIP immunoreactivity. VIP-LI fiber branches were sometimes seen going along the vessels in the BST. (2) VIP-LI cells were usually distributed in areas where the terminals were relatively sparse. In the central part of the oval nucleus, the VIP-LI cells were most concentrated, though the total number of it was less than that in the caudal part of the anterior dosal area, They were usually small fusiform in shape, however some were trangular or multipolar.

BACKGROUND: The rehabilitation outcome varies in stroke patients,and there are differences in the literatures about the influence of factors on the functional recovery in such patients.,OBJECTIVE: To evaluate the pre-rehabilitative and post-rehabilitative effects of stroke patients by functional independence measure (FIM) that is widely used, and analyze the influence of gender, age, motor and cognitive functions at admission, time interval from stroke onset to arrival at rehabilitative admission, comorbidity occurrence, laterality of lesion on the functional recovery of stroke patients.DESIGN: Before-after control observationSETTING: Center of Rehabilitation Medicine, Shandong Provincial Hospital; Faculty of Rehabilitation Medicine, Capital University of Medical SciencesPARTICIPANTS: From March 2000 to December 2002, 55 stroke patients were selected from Shandong Provincial Hospital. They were all first episode, and patients whose bilateral cerebral hemisphere were involved were excluded.METHODS: After the vital signs were steady, the stroke patients got through risk phase (31-75 days) and were treated with medicine improving microcirculation and providing neurotrophic factor for nerves. In addition, they accepted comprehensive rehabilitation training of Bobath technique, PNF technique and Rood method mainly, with 1-2 hours per day and five times per week.MAIN OUTCOME MEASURES: The patients were evaluated within 7days after admission and reassessed 3 days before discharge using FIM,including 18 items of motor and cognitive functions and 126 total scores (108-126 as elementarily or completely independent, 72-107 as mildly dependent, 54-71 as moderately dependent, 36-53 as severely dependent,18-35 as extremely or completely dependent). Multiple stepwise regression equation was applied to analyze the relation of above factors and functional recovery (increased value of FIM total score).RESULTS: Totally 55 patients were involved into the result analysis.①FIM total score of patients was significantly higher at discharge than at admission (93.8±12.0, 68.8±11.6, P ＜ 0.001), and motor function and cognitive function at discharge also increased compare with at admission (P ＜ 0.001).②Mean value of FIM motor score increased everyday was identical with that of total score (0.56±0.21, 0.59±0.21), and higher than mean value of cognitive score (0.03±0.03).Multiple stepwise regression analysis showed,scores of motor and cognitive status at admission, age, time interval from stroke onset to arrival at rehabilitative admission all affected the increased value of FIM total scores. No significant association between gender, comorbidity, laterality lesion of paralysis and functional recovery was observed (P ＞ 0.05). The most influential factors were orderly motor function,cognitive function at admission, age and time interval from stroke onset to arrival at rehabilitation admission.CONCLUSION: Motor and cognitive function at admission, age and time interval from stroke onset to arrival at rehabilitative admission have a no table relationship with functional recovery of stroke patients, especially motor function at admission is positively related. Thus we should not neglect the influence of these factors when conducting rehabilitative treatment.
