Objective To observe the distribution and imaging of radiolabelled arginine-glycineaspartic(RGD)peptide(99Tcm-3P4-RGD2)in collagen-induced arthritis(CIA),and to investigate the possibility of new markers for monitoring the angiogenesis of rheumatoid arthritis(RA)before and after treatment by single photon emission computed tomography(SPECT)labelled with 99Tcm-3P4-RGD2.Methods Type Ⅱ chicken collagen was injected into the tails of Wistar rats to establish arthritis models.The CIA-Wistar rats were randomly divided into three group:the Avastin group,the recombinant human tumor necrosis factor-α receptor Ⅱ group,and the blank control group.The changes of the arthritis index,joint pad thickness and radiological of T/NT before and after treatment were observed.The level of vascular endothelial growth factor(VEGF)in the serum was measured by enzyme-linked immuno sorbent assay(ELISA).The back metapedes pathological section was analyzed by Hematoxylin and Eosin stain(HE)and Safranin O stain as well as arthritic pathology index was also scored.The synovial expression level of VEGF was measured by immuno-histochemistry.The stain level of VEGF was assayed by semiquantitative approach.T test was applied for the comparison of two intergroup samples.Results Abnormal radioactive concentration appeared in the arthritis of the CIA-Wistar rats(1.40±0.17,1.32±0.20,1.30±0.08,P＜0.05).Through the treatment of Avastin and recombinant human tumor necrosis factor-α receptor Ⅱ,the radiological of T/NT decreased significantly(0.43±0.14,0.40±0.12,t=17.710,16.812,P＜0.05).After the treatment with Avastin and recombinant human tumor necrosis factor-α receptor Ⅱ,the severity of synovial pannus,joint pad thickness,arthritis index and the expression of VEGF were all decreased.The radiological of T/NT was positively correlated with the indices mentioned above(r=0.753,0.800,0.892,all P＜0.01 respectively with the the rhTNFR:Fc group)(r=0.701,P=0.001;r=0.502,P=0.024;r=0.481,P=0.032 individually with the rhTNFR:Fc group).Conclusion When 99Tcm-3P4-RGD2 is injected through the tail vein of Wistar rats,it can show the pathological changes of arthritis clearly.99Tcm-3P4-RGD2may be the new eikonogen to monitor the angiogenesis of RA before and after treatment.

Objective To evaluate the interventional of bare-handed core muscle strength training and the sling exercise therapy (SET) on low back pain.Methods The soldiers of an Air Force Station who suffered from low back pain participated in the study.One hundred and forty-four patients were equally divided into three groups: the core muscle strength group (using core muscle strength training and the general physical therapy), the SET group (using SET and general physical therapy), and the control group (using the general physical therapy).All the groups were tested for 6 weeks.Questionnaires were distributed to the three groups before intervention, two weeks, four weeks and six weeks after intervention in order to find out about the degree of LBP, lumbar function and activity of these cases.Changes in the lumbar muscle strength were observed.Results The number of the patients who completed the test included 43 cases in the bare-handed core muscle strength group, 43 cases in the SET group and 44 cases in the control group, respectively, the VAS scores were 3.25, the Roland scores were 5.83,the FFD scores were 8.58 of the bare-handed core muscle strength group;the VAS scores were 3.30, the Roland scores were 5.93,the FFD scores were 8.10 of the SET group;the VAS scores were 2.41, the Roland scores were 3.03,the FFD scores were 7.40 of the control group.The LBP intervention efficiency of the three groups was 90.90%, 85.13% and 46.82%, respectively.There was no significant difference in indexes between the test groups(P>0.05).But compared with the control group,there was significant difference(P<0.05).Conclusion The bare-handed core muscle strength training and SET have obvious effects on LBP cases.According to their own infrastructure and facilities, military health care organizations in different environments can intervene in LBP cases with the bare-handed core muscle strength training or SET to alleviate the pain effectively.

Objective To study the risk factors of hematoma enlargement in acute hypertensive cerebral hemorrhage (AHCH) patients within 24 hours after onset. Methods A retrospective review of clinical data of consecutive patients with AHCH who met the inclusion and exclusion criteria and admitted from Mar. 2008 to Mar. 2013 was performed. The patients' data included patients' demography, previous medical history, clinical features, findings of CT, results of laboratory examinations, and the use of traditional medicines for promoting blood circulation. Patients were divided into hematoma enlargement group and non-hematoma-enlargement group. Univariate analysis was performed on the above factors first, and then with the statistically significant factors used as independent variables, hematoma growth as dependent variables, logistic regression analysis was performed to investigate the possible independent relevant factors for the early enlargement of hematoma in AHCH patients. The risk factors and enlargement of hematoma served as independent variables, the data of mRS scale obtained from 3-month follow up as dependent variables, logistic regression was then performed to investigate the influence of acute hematoma enlargement during 3-month follow up in AHCH patients. mRS 0-2 was assigned as good recovery, and mRS 3-6 as serious disability or death. The inspection level was ct=0.05. Results Among 256 patients, 43 (16.8%) were found to have hematoma enlargement. Univariate analysis showed the risk factors led to hematoma enlargement in AHCH patients were gender (male), Glasgow coma scale at admission, NIHSS (National Institute of Health Stroke Scale) at admission, course of disease, and liver function (AST). However, only two factors, namely gender (male) and course of disease, were the independent risk factors of the hematoma enlargement in AHCH patients according to the multivariate regression analysis. In addition, logistic regression revealed that the hematoma enlargement was the independent risk factor influencing the final outcome of AHCH patients, and the hematoma volume, NIHSS, and course of disease were the independent risk factors influencing the outcome of 3 month follow up. ConclusionsA male AHCH patient with shorter duration from onset to admission (within 2 hours) should alert attending physician there would be a risk of hematoma expansion. Larger amount of bleeding, enlarged hematoma, higher NIHSS and shorter duration from onset to admission herald a poor prognosis.

Neurotransmitter release during synaptic transmission is mediated by presynaptic active zone. Multiple protein components at the active zone region interact and coordinate with each other to control and regulate docking, priming and fusion of the synaptic vesicles with presynaptic membrane, and to further maintain the normal transmitter release process. This review will discuss the structure, the formation, and the functional regulation of active zones.

Low back pain is becoming an important factor affecting people's quality of life, while the age of its onset is getting younger and younger, and the social and economic losses caused by low back pain are huge every year. Intervertebral disc degeneration (IDD) is an important cause of low back pain. Due to multiple factors, biomechanical and structural changes occur in intervertebral disc tissue, including rupture of annulus fibrosus, protrusion of nucleus pulposus, which cause compression of spinal cord and nerve root, and lower back pain. Micro-RNA (miRNA) is a kind of single-stranded non-coding small molecule RNA, with 18-24 nucleotides in length, which exists widely in eukaryotes. As one of the important regulatory molecules of gene expression, it has been proved to play a key role in the initiation and progression of many diseases, and it may also play an important role in intervertebral disc degeneration. At present, the clinical treatment for IDD is mainly surgical treatment to alleviate clinical symptoms. Even if surgical treatment can achieve good results, it will bring great physical trauma and economic burden to patients. The role of miRNA in IDD is one of the hotspots in the current academic research. Studies have shown that miRNA has abnormal expression patterns in degenerative intervertebral disc tissues and participates in a variety of pathological processes of IDD. At present, some miRNAs have been proved to be related to a variety of pathological processes in IDD, including nucleus pulposus cell apoptosis and proliferation, extracellular matrix degradation, autophagy, inflammation and cartilage endplate degeneration. The comparative study of gene chip showed that there were significant differences in the expression of some miRNAs between degenerative and normal nucleus pulposus cells. These differentially expressed miRNAs may be involved in the process of nucleus pulposus cell degeneration by regulating their respective upstream or downstream pathways. Most of the regulatory pathways are crossed and parallel, thus constructing a huge miRNA regulatory network. Understanding the target genes and mechanisms of miRNA in the pathogenic process can provide an important reference for the origin, development and prognosis of IDD. In this article, the important role of miRNA in IDD and the potential significance of clinical treatment are reviewed. With the in-depth study of miRNA and the molecular biological mechanism can provide new ideas for the diagnosis and treatment of IDD, which is likely to become a new strategy for biological treatment of IDD.
