A case report of ligamentum flavum cyst in the lumbar vertebral canal and literature review / 中华老年医学杂志

Ligamentum flavum cysts in the spinal canal are rare space-occupying lesions.They usually occur in the middle-aged and people over 50 years old, without obvious sex or regional differences, and mostly involve the cervical, thoracic and lumbar vertebrae, especially the lumbar vertebrae(L4/5 and L5/S1). There are no characteristic manifestations for ligamentum flavum cysts.They can cause neurological symptoms due to compression of nerve roots or the dural sac.For example, patients with lumbar ligamentum flavum cysts may complain of symptoms of lumbar disc herniation-related sciatica, which can easily lead to misdiagnosis.Surgical excision of the cyst is the most effective method.Recently, one patient with this disease was admitted to our department.After surgical fenestration, the ligamentum flavum cyst in the lumbar canal was resected and its diagnosis was eventually confirmed histologically.After 17 months of follow-up, the patient recovered well.

Application progress of polymyxin in bloodstream infection of drug-resistant Acinetobacter baumannii / 中华危重病急救医学

In recent years, the bloodstream infection rate of Gram-negative bacilli has continued to increase. Among them, drug-resistant bacteria have a higher mortality rate and longer hospital stay, especially the bloodstream infection of carbapenem-resistant Acinetobacter baumannii (CRAB). Polymyxin began to be used clinically in the 1950s and has antibacterial activity against multidrug resistant and poly drug-resistant Gram-negative bacilli. It can also be used as an effective permeation agent for the cell envelope of Gram-negative bacilli. Polymyxin is reserved for microbiologically clear drug-resistant Gram-negative bacilli infections. The World Health Organization classifies polymyxin as an antimicrobial drug with clinical significance for human infections and can be used to treat drug-resistant Acinetobacter baumannii infection. This article reviews the clinical treatment of polymyxin in bloodstream infections of drug-resistant Acinetobacter baumannii, to provide reference for clinical medication.

The neural mechanism of motor imagery training′s motor recovery effects after stroke / 中华物理医学与康复杂志

Objective:To explore the mechanism of motor imagery training (MIT) combined with conventional rehabilitation to promote the functional recovery of upper limbs in stroke survivors. To explore the brain network reorganization resulting when motor imagery training (MIT) is combined with conventional rehabilitation to promote the motor recovery of stroke survivors.Methods:Fourteen hemiplegic patients were recruited as the MIT group. They underwent 4 weeks of MIT (30 min/day, 5 days/week) along with conventional rehabilitation treatment. The upper limb section of the Fugl-Meyer assessment (FMA-UE) and the modified Barthel Index (MBI) were used to assess all of the patients, and resting-state fMRI was performed before and after the treatment. Twenty-eight age- and sex-matched healthy subjects also received one-time resting-state fMRI scanning. Granger causal analysis was performed in the MIT group to calculate the changes in effective connection between the ipsilesional primary motor cortex and the whole brain before and after the treatment, and the results were compared with the healthy control group.Results:After the treatment, the average FMA-UE and MBI of the MIT group had increased significantly. Before the intervention, the effective connection mode of the ipsilesional M1 area in the MIT group was significantly different from that of the healthy controls. The causal flow from the ipsilesional M1 area to the bilateral prefrontal cortex had increased abnormally and the causal flow from the contralesional primary motor cortex, the inferior parietal lobule and the cerebellum to the ipsilesional M1 area had decreased significantly. After the treatment, the effective connection pattern of the stroke survivors was nearly normal, and the causal influence from contralesional motor imagery-related brain areas (the superior parietal lobule, inferior parietal lobule, thalamus and the fusiform gyrus) to the ipsilesional M1 area was enhanced. Effective connection from the ipsilesional M1 area to the contralesional cerebellum before the intervention was positively correlated with the improvement in FMA-UE scores, and the effective connection from the contralesional middle frontal gyrus to the ipsilesional M1 area was correlated negatively.Conclusions:The neural mechanism of MIT's effectiveness when it is combined with conventional rehabilitation might be related to the reorganization of effective connections. That would include enhanced causal flow between motor imagery-related brain areas and the contralesional cerebellum and ipsilesional M1 area. Down-regulation of the effective connection from the contralesional middle frontal gyrus to the ipsilesional M1 area also occurs.

The effects of motor imagery training and conventional therapy on the functioning of stroke survivors: A resting-state fMRI study / 中华物理医学与康复杂志

Objective To measure the efficacy of combining motor imagery training ( MIT) with convention-al therapy in improving stroke patients′upper-extremity function. And to seek a cortical reorganization mechanism as-sociated with the improvement using resting-state functional magnetic resonance imaging ( rs-fMRI) . Methods Ten stroke survivors were selected as an experimental group. They were given motor imagery training for four weeks ( 30 minutes a day, 5 days a week) and conventional rehabilitation therapy ( 40 minutes a day, 5 days a week) . Another 10 healthy counterparts were the control group. Before and after the four weeks of treatment, both groups were as-sessed using the upper extremity Fugl-Meyer assessment ( FMA-UE) and the modified Barthel index ( MBI) . Moreo-ver, rs-fMRI was conducted to assess functional connectivity between cortical regions and the ipsilesional primary mo-tor cortex ( M1) before and after the intervention. The laterality index ( LI) of the primary motor or sensory cortex was also calculated. Results After the intervention, the average FMA-UE and MBI scores of the experimental group had increased significantly. After MIT and conventional therapy there was increased functional connectivity between the ip-silesional and contralesional M1 areas, and between the ipsilesional M1 and contralesional primary sensory cortex ( S1) and frontal lobe, the functional connection between the ipsilesional M1 and the ipsilesional paracentral lobule and the anterior cingutate was also increased. More specifically, the LI relating M1 and S1 decreased after the inter-vention, tending toward the normal level. LIMI decreased significantly. Conclusion The 4-week regimen of motor imagery training and conventional therapy resulted in functional improvement in the upper limbs and greater ability in the activities of daily living. The observed improvements may be due to cortical reorganization, including better func-tional connectivity between the bilateral M1 areas and increased connectivity between the ipsilesional M1 area and some non-motor areas. There is some recovery of symmetry in the bilateral primary motor cortex.

Assessment Value of Disrupted Corticospinal Tract Secondary to Stroke Lesion for Motor Impairment: A Diffusion Tensor Tracking Study / 中国康复理论与实践

@#Objective To investigate the relationship between disrupted corticospinal tract (CST) and motor recovery after stroke by using diffusion tensor tracking (DTT). Methods From March, 2012 to June, 2013, 15 chronic stroke patients with left subcortical lesions and 15 age- and sex- matched healthy subjects were performed diffusion tensor imaging (DTI) examination. The CST was tracked by DTT technique, and the damaged values of the CST caused by the stroke lesions were quantified using a CST template generated from healthy controls. Furthermore, the correlations of the damaged values of the CST with Fugl-Meyer Assessment (FMA) were performed. Results The range of the damaged values of CST in stroke patients was 0.00% to 29.6%. There were very strong negative correlation between the damaged values of the CST and FMA scores (the wrist, r = -0.660; hand, r = -0.813; wrist plus hand, r = -0.795, respectively, P < 0.01). It also showed strong negative correlation between the damaged values of the CST and FMA scores (upper limb, r = -0.614; upper limb plus lower limb, r = -0.563, respectively, P < 0.05). Whereas, there was no correlation between the damaged values of the CST and FMA scores of lower limb (r = -0.270, P = 0.331). In addition, the lesion volumes of stroke and FMA scores were not significantly correlated (P > 0.05). Conclusion The severity of motor deficit after stroke was closely related to the overlap of lesions with CST. The damaged values of the CST based on DTT may be used as a potential biomarker to assess motor impairments of upper limbs, especially hand and wrist in stroke patients.

The clinical significance and biological function of microRNA-106b in thyroid cancer / 中华内分泌外科杂志

Objective To investigate clinical significance and function of microRNA-106b (miR-106b) in retinoblastoma tissues and cells.Methods We detected miR-106b expression in 51 samples of thyroid cancer and the adjacent non-tumor tissues using qRT-PCR.The expression of miR-106b was altered by corresponding vectors in thyroid cancer cells,and then BrdU cell proliferation and flow cytometry assay were performed to examine the proliferation and apoptosis of thyroid cancer cells.Results The expression of miR-106b in thyroid cancer tissues was significantly lower than that in normal tumor-adjacent tissues (0.36±0.029 vs 0.98±0.034,P＝ 0.004).MiR-106b expression in tumor tissues was significantly associated with tumor size and tumor number.MiR-106b was obviously inhibited by miR-106b inhibitor in PTC-I cells (0.96±0.025 vs 0.29±0.032,P＝0.001),and inhibition of miR-106b resulted in significantly increased proliferation (89.33±5.67 vs 136.67±10.33,P＝0.03) and decreased apoptosis (16.33±3.20 vs 7.67±2.45,P＝0.04).On the contrast,over-expression of miR-106b using miR-106b mimics led to significantly decreased proliferation (98.00±4.65 vs 76.33±2.87,P＝0.03) and increased apoptosis (22.54±2.13 vs 32.45±4.34,P＝0.04).Conclusions Decreased expression of miR-106b is correlated with the adverse clinicopathological features of thyroid cancer.MiR-106b can inhibit cell proliferation and apoptosis of thyroid cancer cells,suggesting miR-106b plays a suppressive role in development and progression of thyroid cancer.

Magnetic resonance imaging of active, passive and imaginary movement / 中华物理医学与康复杂志

Objective To assess any differences in brain activation during active,passive and imaginary movement of the hands using blood oxygen level-dependent functional magnetic resonance imaging (fMRI),and to provide references for the cortical reorganization in patients with brain injuries.Methods Twenty healthy,righthanded,adult volunteers were studied,fMRI was performed during active,passive and imaginary fist clutching.Whole brain analysis and group analysis were applied to get the voxels,the volume of activation,the peak t-score and its coordinates.Results Active and passive movement both produced significant activation in the contralateral sensorimotor cortex,the contralateral supplementary motor area and the ipsilateral cerebellum.The sensorimotor cortex was the most frequently and most strongly activated brain area.Imaginary movement produced significant bilateral activation in the supplementary motor area.Conclusions Active and passive movement induce similar brain activation patterns.This indicates that passive might replace active movement when observing activation of the brain's cortex during the rehabilitation of patients with hemiplegia.

Production and mechanism of CCL5 by macrophages in U14 cervical cancer-bearing mice during infection / 中华妇产科杂志

Objective To investigate the production and mechanism of chemokine (C-C motif) ligand 5 (CCL5) by macrophages in U14 cervical cancer-bearing mice during infection. Methods The U14 cervical cancer cells were injected in C57BL/6 mice to induce tumor-bearing condition. Lipopolysaccharide (LPS) was injected into C57BL/6 mice to induce infection. The protein expression of CCL5 in the serum and the CCL5 mRNA expression in inflammatory cells were measured by ELISA and fluorescence quantitative-PCR in four groups. Macrophages were induced in the tumor conditioned medium (TCM) which extracted from mice serum. The protein expression levels of CCL5, prostaglandin E2 (PGE2) and cyclic adenosine monophosphate (cAMP) in the medium and CCL5, PGE2 and cAMP mRNA expression in the macrophages were detected in different groups. In order to determine whether the inhibition was related to PGE2, selective cyclooxygenase 2(COX-2) inhibitor NS398 was used to reverse this phenomenon and protein kinase A (PKA) inhibitor H89 demonstrated the mechanism through blocking cAMP/PKA signaling pathway. Results (1) The protein and mRNA level of CCL5 in tumor-bearing mice were respectively (151±35) pg/ml and 1.0, which were lower than those in the tumor-free mice (691 ± 85) pg/ml and 4.5 ± 0.8, there were significant difference between them (all P<0.05). The protein and mRNA level of PGE2 in tumor-bearing mice were (1 198±83) pg/ml and 5.8±0.8, which were higher than those in the tumor-free mice (187±25) pg/ml and 1.0, the difference were significant (all P<0.05). The protein and mRNA level of CCL5 in tumor-free+LPS mice were (4 049±141) pg/ml and 31.5±2.0, which were higher than those in the tumor-bearing+LPS mice (1 951±71) pg/ml and 12.1±2.8, the difference were also significant (P<0.05). The protein and mRNA level of PGE2 in tumor-free+LPS mice were (676±70) pg/ml and 3.4±0.4, which were lower than those in tumor-bearing+LPS mice (2 550±382) pg/ml and 11.6±0.9, the difference were also significant (all P<0.05). (2) Macrophages were cultured in vitro using TCM derived from mice. The protein and mRNA level of CCL5 in tumor-bearing mice TCM were respectively (1 626 ± 177) pg/ml and 28.6 ± 1.2, which were higher than those in the tumor-free mice TCM [(27 ± 3) pg/ml and 1.0], there were significant difference (P<0.05). The protein and mRNA level of PGE2 in tumor-bearing mice TCM were (790 ± 156) pg/ml and 1.7 ± 0.3, which were higher than those in the tumor-free mice TCM [(448 ± 115) pg/ml, 1.0], the difference were significant (all P<0.05). The protein and mRNA level of cAMP in tumor-bearing mice TCM were (164 ± 30) pg/ml and 1.6 ± 0.3, which weres higher than those in the tumor-free mice TCM [(118 ± 25) pg/ml,1.0], the difference were significant (all P<0.05). The protein and mRNA level of CCL5 in tumor-free + LPS mice TCM were (10 475 ± 742) pg/ml and 212.0 ± 5.7, which were higher than those in the tumor-bearing+LPS mice TCM [(6 375±530) pg/ml, 142.3±2.5], the difference were significant (all P<0.05). The protein and mRNA level of PGE2 in tumor-free+LPS mice TCM were (2 438±95) pg/ml and 4.3±0.7, which weres lower than those in the tumor-bearing + LPS mice TCM [(3 441 ± 163) pg/ml, 5.9 ± 0.3], the difference were significant (all P<0.05). The protein and mRNA level of cAMP in tumor-free+LPS mice TCM were (340 ± 13) pg/ml and 4.1 ± 0.4, which were lower than those in the tumor-bearing + LPS mice TCM [(542 ± 42) pg/ml, 5.4 ± 0.5], the difference were significant (all P<0.05). (3) Using COX-2 inhibitor NS398 in the tumor-bearing+LPS mice, the protein and mRNA level of CCL5, PGE2 and cAMP were (7 691±269) pg/ml and 159.0±8.9, (2 820±152) pg/ml and 4.9 ± 0.3, (465 ± 8) pg/ml and 4.3 ± 0.4, respectively, and there were significant difference (all P<0.05), compared to before treatment.

Effects of rehabilitative exercise on patients with cervical spondylosis in communities / 中国组织工程研究

BACKGROUND: Cervical spondylosis is a common disease in middleaged and elderly people. There are many methods of rehabilitative treatment such as traction, massage, medical gymnastics, acupuncture and local blocking, etc.OBJECTIVE: To observe the effects of rehabilitative exercise on patients with cervical spondylosis by way of quantitative generalized boxing exercise combined with local cervical medical exercise.DESIGN: Self-control study on patients with cervical spondylosis in the community for 3 monthsSETTING: Department of Rehabilitation Medicine, Huashan Hospital Affiliated to Fudan University PARTICIPANTS: The indoor questionnaire investigation about chronic diseases in community was carried out on 1 457 inhabitants with the age from 35 to 74 in a community of South Nanjing district, Shanghai in order to check out the patients with cervical spondylosis who had been diagnosed confirmatively by hospital and exclude the patients with the disease of spinal cord type. There were total 114 patients volunteering to participate in the 3-month rehabilitative treatment with an informed content, including of 12 with cervical type of the disease, 39 with nerve root type, 23 with vertebroarterial type, 5 with sympathetic nerve type, 35 with mixed type and none with spinal cord type.METHODS: 3-month rehabilitative exercise was carried out for the 114 patients with cervical spondylosis.① One or several kinds of generalized boxing exercise such as shadow boxing, eighteen-gesture training practice and joint exercise were chosen by the patients according to their own in terest and physical energy. It was required that patient exercise was done for 3 months with one time a day, and each time for no less than 30 minutes, with the intensity after each exercise arriving to the target heart rate level of 170 subtracting their age. ② Aiming to exercise the cervicalshoulder part and to relax its related functions, the local cervical medical exercise has 12 procedures including turning left and right, moving neck around, shrinking head and relaxing shoulders, stretching neck and extending back, turning head and watching the moon, waving arms, putting up arms, lifting chest and squaring elbows, and trying hard to stretch neck.It was required that each procedure be repeated 5 to 10 times at the beginning and later more times increasing gradually, and the whole set of exercise be practiced for 3 months with lor 2 times each day and each time lasted at least 10 minutes.③No other treatment was performed by the patients except for the above exercise intervention. The effects were evaluated after 3 months.MAIN OUTCOME MEASURES: ①The evaluated results of the curative effect in all patients with 3-month rehabilitative exercise.② Relationship between types of cervical spondylosis and curative effect ③ Relationship between course of disease and curative effect RESULTS: According to the intention-to-treat analysis, all the 114 patients persisting in the 3-month exercise intervention entered the result analysis. The curative effect evaluation: among the 114 patients, 44 were with the general curative effect, 40 with marked improvement, 25 with improvement, 5 with inefficacy. The percentage of the general curative and marked improved is 73.7%, and that of total improvement is 95.6% The clinical manifestations of all patients with cervical spondylosis including cervicoscapulargia, radioactive numb and pain in unilateral or bilateral upper arms, dizziness, tinnitus, headache, etc.were distinctively improved ② Relationship between the types of cervical spondylosis and curative effect: after 3-month treatment of rehabilitative exercise, the percentage of the general curative effect and marked improvement in patients with cervical type and nerve root type was higher than that in patients with verteboarterial type, sympathetic nerve type and mixed type (91.7%,97.4%, 47.8% ,20.0% ,65.7% respectively and p value below 0.01). ③ Relationship between the course of cervical spondylosis and curative effects: the percentage of the general curative effect and marked improvement in patients with the course of less than one year is 90.9% and that in patients with the course of 1 to 5 years is 88.6%, which were all higher than that in patients with a course of 5 more years (p value below 0.01).CONCLUSION: Quantitative generalized boxing exercise combined with local cervical medical exercise is helpful to improve the radiculopathy symptoms, but only combined with other treatments could patients with vertebroarterial type receive the best curative effect. In addition, there is a certain relation between the course of disease and curative effect, and patients with cervical spondylosis should be treated with rehabilitative exercise as early as possible, which suggestes that it is worthy of popularization that patients with cervical spondylosis are organized to practice quantitative boxing exercise combined with cervical medical exercise in the community.

Role of high resolution CT in diffuse pulmonary nodules / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate high resolution CT (HRCT) in the diagnosis of diffuse pulmonary nodules.</p><p><b>METHODS</b>Fifty normal chest radiographs, conventional CT and HRCT were used to evaluate the visualization of pulmonary lobule. The configuration, distribution and intrinsic structure of lesion in 38 patients with diffuse pulmonary nodules were analyzed by HRCT.</p><p><b>RESULTS</b>The chest radiographs were not able to show the structure of pulmonary lobule. The visualization rates of pulmonary lobule were 20% by conventional CT and 50% by HRCT (P < 0.05). Of 38 patients with diffuse pulmonary nodules, 19 had interstitial nodules which were located in the pulmonary intestities, the lobular septa and under the pleura. HRCT could clearly show their para-bronchial distribution with clear cut margin. Four had airspace nodules, chiefly shown as solidification of the air spaces. There was no nodule beneath the pleura or in the lobular septa. HRCT revealed even density and hazzy margins. Fifteen had randomly distributed nodules, with the nodules scattered at random. HRCT showed nodules with high density, sizes varying greatly but the margin was clear.</p><p><b>CONCLUSION</b>High resolution CT is able to show the pattern of distribution, intranodular structures and background of the diffuse pulmonary nodules, which is valuable in the diagnosis and differential diagnosis of this disease.</p>

Survey on Present Situation of Sport Participation in the Residents of East Nanjing Road Community in Shanghai / 中国运动医学杂志

To understand the present situation of sport participation in community residents of Shanghai，study infecting factors to the regular sport participation rate and evaluate recognition degree of the relationship of sport and chronic disease，we carried out questionnaire survey indoors among the permanent residents,aged 35～74,in East Nanjing Road community, including survey on chronic disease and sport participation situation. The material was statistically analyzed and the related factors were proved by x2 test. The results showed that in 1457 permanent residents,470 regularly participat in sport, and were classified as sport population. The prevalence was 32.3%.The gender, age, education level, occupation and chronic disease had statistical significance (P<0.05) and they were probably infecting factors of the regular sport participation rate. Currently,the regular sport participation rate in community is relatively high and the purpose of sport participation was evident, however, the age structure of sport population was imbalance. The sport participation in residents was individualized and without proper scientific instruction.
