Objective To assess atrophy of the multifidus in elderly patients with low back pain using magnetic resonance imaging.Methods Thirty patients with low back pain were recruited,and 15 healthy subjects formed a normal group.The cross sectional area (CSA) and signal strength of the multifidus muscles at the L4-5 and L5-S1 levels were measured along with the signal strength of the hip fat for all of the subjects in both groups using a superconducting magnetic scanner.Results There was no statistically significant CSA difference between the groups at either level.The contrast between multifidus muscle and adipose tissue was significantly different between the groups at both levels.Conclusion In evaluating atrophy of the multifidus muscle in elderly patients with low back pain,the contrast between multifidus muscle and adipose tissue at either level L4-5 or L5-S1 can be used for assessment.It is more reliable,specific and sensitive than the CSA of the muscle.

Objective To determine the expressions of transcription factor activator protein-2α (AP-2α), estrogen receptor-β (ER-β) and matrixmetalloproteinase-9 (MMP-9) in lichen planus (LP) lesions and their significance. Methods Tissue samples were resected from the lesions of 30 patients with LP and normal skin of 30 human controls. An immunohistochemical method using streptavidin-peroxidase (SP) was performed to detect the expression of ER-β and MMP-9, reverse transcription-PCR and Western blot to measure the mRNA and protein expressions of AP-2α, ER-β and MMP-9 in these specimens. Results There was a significant decrease in the mRNA expressions of AP-2α (0.488 ± 0.039 vs. 1.008 ± 0.023, P < 0.01 ) and ER-β (0.365 ± 0.032 vs. 0.998 ± 0.036, P < 0.01), together with an increase in the expression of MMP-9 (1.237 ± 0.027 vs. 0.567 ± 0.015, P< 0.01) in the LP lesions compared with the control specimens; similar results were observed for the protein expressions of AP-2α, ER-β and MMP-9. In LP lesions, the expression of AP-2α was positively correlated with that of ER-β (R = 0.89, P < 0.01), but negatively correlated with that of MMP-9 (r = -0.91, P < 0.01). Conclusions The down-regulation of ER-β expression and up-regulation of MMP-9 expression may be ascribed to the abnormal regulation of upstream target genes mediated by the decreased expression of AP-2α, which may be involved in the pathogenesis of LP.

ObjectiveTo evaluate effects of post-operative analgesia combined with parental presence on emergence agitation after sevoflurane anesthesia in children. Methods60 patients were randomly assigned into three groups with 20 cases each. After sevoflurane inhalation and being given rocuronium, all patients were intubated for mechanical ventilation. Then patients received caudal block. Patiens in group A and B were treated with diclofenac sodium suppositories before operation. To maintain anesthesia patients were adopted sevoflurane inhalation. Patients in group A and C were cared by nurses in post anesthesia care unit, whereas patients in group B added parental presence. Emergence agitation incidence, modified Aldrete scale, PAEDS, CHEOPS were all recorded. ResultsTherewas no difference of modified Aldrete scale among three groups( F =0.652 ,P ＞0. 05) ,but emergence agitation incidence in group C was more than those of group A and B. At each point PAEDS scores of group B were lower than those of group C( x2 =4. 566,7. 234,4. 124,6. 126, P ＜ 0. 05) ,also scores of group B were lower than those of group A at 10 min and 30 min(F=0.654,P＞0.05). PAEDS scores of group A were lower than those of group C at 20min and 30min(t =3.256,3.778,4.556,4.223 ,all P＜0.05). At 20min and 30min CHEOPS scores of group C were higher than those of group A and B ( F =1. 987, P ＞ 0.05 ). ConclusionPost-operative analgesia combined with parental presence could decrease the incidence of emergence agitation after sevoflurane anesthesia in children.

BACKGROUND:Cytomegalovirus is one of the opportunistic infection viruses for organ transplant patients, and it can lead to functional loss of organ grafts and even endanger lives. Therefore, accurate diagnosis of cytomegalovirus infection at early phase is the key to clinical treatment. OBJECTIVE:To analyze the detection method, accuracy, detection time and clinical significance of cytomegalovirus infection after organ transplantation. METHODS: A computer-based search of VIP, PubMed and CNKI as wel as manual search of books were performed for literatures concerning organ transplantation and cytomegalovirus infection published from January 2007 to December 2014. The keywords were transplantation, cytomegalovirus in English and Chinese, respectively. Total 1 894 papers in English and 31 articles in Chinese were found. Among them, only 35 papers which were highly representative and published in related authoritative journals were chosen for further analysis. RESULTS AND CONCLUSION:The main non-invasive detection of cytomegalovirus infection is stil the test of CMV-pp65 antigen with good sensitivity and specificity which can accurately reflect the status of cytomegalovirus infection. This method is also the most important clinical diagnostic method. Molecular biological detection of cytomegalovirus can detect potentialy infected people, and this method can detect the infection earlier than CMV-pp65 antigen method, which is suitable for the early diagnosis of cytomegalovirus infection and early drug treatment. Quantitative nucleic acid test can be used to analyze cytomegalovirus-DNA copies so as to determine the concentrations of the virus in patients, which may provide a more sensitive monitoring way for inapparently infected patients. Cytomegalovirus-IgG and cytomegalovirus-IgM in serum can be used to determine whether organ transplant recipients have been infected by cytomegalovirus. Virus culture and histological examination have been used for several years, both of which are the gold standard for detecting cytomegalovirus. However, these methods cannot be used in early diagnosis and active infection. Immunological detection method provides a new ideal for the diagnosis of cytomegalovirus infection. This method can monitor cytomegalovirus infection from early phase accurately and assess the risk of cytomegalovirus, providing a new way for the development of the diagnosis of cytomegalovirus infection.

Objective To investigate the correlation between mental status of patients with stroke and their quality of life. Method One hundred and three stroke patients were measured by HRSD,HMAM and SS-QOL to explore the correlation between mental status and quality of life.Results Among the 103 patients,68 developed depression, taking up 66.02%,with a total score of 31.62±12.58;52 anxiety,taking up 50.49%,with a total score of 22.17±5.38.The level of depression and anxiety were negatively correlated with the life quality(P<0.01).Conclusions The occurence rate of depression and anxiety in stroke patients is higher. The higher the scores on depression and anxiety,the worse the quality of life.

Autoimmune disease is an own organization inflammatory lesions,mainly caused by destroying the adaptive immune tolerance mechanism of differentiatingself andnon-self,whose character is appearing the autoantibodies and self-reactive T cells in the body.Autoinflammatory disease is a group of genetic,recurrent and noninvasive inflammatory disease,whose characteristics are fever,rash,joint pain,arthritis,ophthalmic pathological changes and increasing of acute phase proteins,and it can affect many organ systems.These diseases are different in the mode of onset and clinical manifestations,but also can have similar and overlapped symptoms and signs,and often confused with other systemic diseases.Therefore,clinical misdiagnoses or missed diagnoses easily occur.To understand correctly and master the laboratory examination characteristics and its clinical is essential,which has significant value in the clinical diagnosis,differential diagnosis,evaluation and treatment of these diseases.
