Objective To study the value of routine laboratory examinations, symptoms and soluble IL-2 receptor (sIL-2R) in the flare-prediction on systemic lupus erythematosus(SLE). Methods A prospective study was performed in 106 outpatients with SLE and the patients′ conditions were assessed according to Systemic Lupus Erythematosus Disease Activity Index(SLEDAI). Patients were asked to visit at no longer than 3-month interval. All patients were followed-up for 6 to 18 months. At each visit, laboratory examinations, symptoms, disease activity, as well as the changes in the treatment were recorded according to the protocol. The values of these parameters in flare-prediction were comprehensively assessed based on their frequency and time respectively when they became abnormal before the disease flare. Results Among the 106 patients, the disease activity of 67 cases were in remission and satisfied the prospective study criteria of the SLE flare. Thirty-one flares in 29 patients were observed. The frequency of flare was 0.44/patient/year. Comprehensively the most valuable predictor of those parameters was anti-dsDNA antibody, followed by complement components, sIL-2R, erythrocyte sedimentation rate(ESR), complete blood count, urine analysis, fatigue, mucous membrane ulceration, new rashes and alopecia. C3 was a better predictor for SLE flares than that of C4 and CH50. Conclusions The flares of SLE could be predicted. Early intervention will help to prevent patients from flare.

10 days.All the patients received operations.Results:The prognoses of 80.49% patients in the early and middle stages were well ,the fadeaway of edema was evident,on the contrary,the prognoses of 83.33% patients of the later stage were worse,the fadeaway of edema was slow.Conclusion:The patients of LEDVT should receive operation as early as possibly in 10 days,the patients should receive conservative therapy after 10 days.

Neurologic complications are rare but devastating events after scoliosis surgery;a thorough preoperative work-up and effective intraoperative monitoring of the spinal cord may reduce the incidence.This review discusses the incidence,preoperative work-up,intraoperative monitoring,and managing strategies for neurologic complications of scoliosis surgery.

Objective To investigate and analyze structure of risk perceived by people using HIV voluntary counseling and testing services and related factors.Method Two hundred and sixty eight VCT users were selected from 2 CDCs and 2 hospitals in Beijing and their perceived risks in the process of VCT were assessed by using self-administered question- naires.Factor analysis was performed to understand the relationship between different perceived risks,and risks perceived by different users were evaluated.Results Six factors were obtained from the factor analysis which included:fear of priva- cy disclosure,embarrassment,concern over the reliability of HIV tests,cost & time consumption,the tragic outcomes of HIV positive tests,and potential medical expenditures in the future.And the risks perceived by low and high income users were much higher than those perceived by middle income users.Conclusion There are clear structure of risks perceived by people using HIV voluntary counseling and testing,and people with different incomes have different levels of perceived risks.

Objective To study the pathogenesis,diagnosis and treatment of the compression syndrome of the third common plantar digital nerves.Methods Conservative methods were at first used for all the 34 cases of this disease.Treatment methods includes:wearing shoes with soft bottom and metatarsal pad;the administration of Chinese herbs;the application of direct current iontherapy by filtering Chinese herbs and performing local injection therapy with steroid at the tenderness points.15 patients with no effect following conservative methods and other 3 recurrent cases were treated with section of deep transverse metatarsal ligament and relaxing the nerves compression.Of the 18 cases,5 had additional to excision of the neuroma.Results Of the 34 cases treated with conservative methods,19 had effective results,of which 6 cases recurred,and 15 cases had no effect.18 cases treated with operation had no recurrence.Conclusion Toe extending test and forefoot transversely compressing test provide a valuable basis for diagnosis.Conservative treatment are usually effective in earlier phase.If conservative treatment is not effective,the transverse metatarsal ligament should be sectioned,nerves should be relaxed and the neuroma must be excised.The results of operative treatment are satisfactory.

Transpedicular screw and rod internal fixation system is the common implants in spinal surgery. Multi-slice spiral CT and magnetic resonance imaging can generate section image, become routine imaging modality in the assessment of the postoperative spinal patients. Magnetic resonance imaging can evaluate the bone marrow and soft tissue, which is the first choice for examination. However, to the patients with metal implants, the existed metal artifacts can decrease the imaging quality. Therefore, multi-slice spiral CT is an important evaluation method for inserted material, os integumentale and anatomy. This article reviewed the production mechanism of metal-related artifacts, influencing factors and decreasing technique.

Objective To study the activity and participation status of patients with spinal cord injury or traumatic brain injury. Methods From 2013 to 2016, 60 patients with spinal cord injury and 38 patients with traumatic brain injury were assessed with WHO Disability As-sessment Schedule 2.0 (WHO-DAS 2.0) (International Chinese Version of fully structured interviewer administered 36 questions). Results The patients with traumatic brain injury had moderate dysfunction in domains of cognition and getting along with people, and severe dys-function in other domains. The patients with spinal cord injury had mild dysfunction in domain of cognition, moderate dysfunction in do-mains of self-care and getting along with people, and severe dysfunction in other domains. The dysfunction was severer in domains of cogni-tion and self-care in the patients with traumatic brain injury than in the patients with spinal cord injury (t>2.140, P<0.05). Conclusion The inpatients with spinal cord injury and traumatic brain injury are difficult in mobility, self-care, getting along with people, life activities and participation.

Objectives： To identify the peptide sequence of a epitope and study its three dimensional structure on molecule of cyclophilin A.　Methods： Using anti oyelophilin A (CyPA) monoclonal antibody (McAb D4) as the capture antibody, the library displayed random heptapeptides was screened by biopanning. The phage clones with high affinity for McAb D4 were chosen and their inserts were sequenced and then the antibody binding site was searched for on three dimensional structure of CyPA with RasMol software.　Results：After 3 rounds of biopanning, 7 phage clones with high affinity for McAb D4 were sequenced and 3 different species were obtained, five of seven clones shared a predominant consensus sequence, WSLQSFL. The amino acid sequences of the inserts were compared with that of human CyPA.No homologous sequence was found in the primary structure of CyPA. With the data from PDB database and RasMol software, we found that W121,S99,L98,Q111,S110,F112 and L122 constructed a hydrophobic pocket which may be the epitope for McAb D4.　 Conclusions： W121,S99,L98,Q111,S110,F112 and L122 may form a conformational epitope of cyclophilin A.
