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.
2.Preliminary Study on Flare-Prediction in Patients with Systemic Lupus Erythematosus
Chinese Journal of Dermatology 1995;0(01):-
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.
3.Prevention and management of neurological complications after scoliosis surgery
Academic Journal of Second Military Medical University 2000;0(08):-
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.
4.Evaluation of risks perceived by people using HIV voluntary counseling and testing services
Chinese Journal of AIDS & STD 2007;0(05):-
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.

A study on the optimal dilution of serum to detect anti HBc-IgM with ELISA. was carried out. Samples were diluted to 10-1to 10-7. Among 26 samples of normal individuals, 22 were negative, but two samples of 10-1 dilution, one sample of 10-2, and one sample of 10-1-10-3 were positive though the control wells were all negative. 42 samples of the patients with variours types of hepatitis B were examined. It was found that when serum dilution was 10-1, only 6 cases were positive; when the dilution was 10-2, 20 cases were positive; when the dilutions were 10-3, 5?10-3, and 10-4, high positive rates were obtained and they were 88.1%, 78.5%, and 69% respectively; and when the samples were further diluted, the positive rate decreased.In order to get goodfresults and minimize false results, either false negative or false positive, it is suggested that 5?10-3 be the optimal dilution.

Objective:To explore psychosocial factors of depressed elderly patients. Methods:33 elderly people with the first episode of depression diagnosed according to CCMD-3, and elderly healthy people were investigated with EPQ, SSRS (social support rating scale), LES (life event scale) and MMSE (mini mental state examination). Results:The rates of psychiatric family history, somatic diseases, risk factors for vascular disease and long-term difficulties were significantly higher in the depressive group than in control group. The score of MMSE was significantly lower in depressive group than in control group. The scores of negative life events and problems in social intercourse were significantly higher in depressive group than in control group. There were lower score of social support and its utility in the depressive group than in control group. The score of neuroticism was significantly higher in the depressive group. Most depressive elderly patients had the personality of neuroticism.Conclusion:Chronic stress, high neuroticism and severe cognitive impairment are important risk factors for depression in late life.[

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 investigate the effect of eosinophils(EOS)in asthmatic guinea pigs airway and explore the mechanism of antiasthma by inhaled arsenic trioxide. Methods The guinea pigs asthma models were established with ovalbumin(OVA)challenge method,2 groups received inhaled different doses of arsenic trioxide,and three control groups respectively received normal saline inhaled and high dose of arsenic trioxide by intraperitoneal injection and dexamethasone(DEX)intraperitoneally. EOS invaded and apoptosis with all of the groups were assessed after 7 days intraperitoneal injection or inhalation. Results Compared with group of inhaled normal saline, both EOS invaded and apoptosis in bronchus submuconsa were significantly different(P0.05)among groups of inhaled low dose arsenic trioxide [2.0 mg(kg?d)]and intraperitoneal injection with higher dose arsenic trioxide[5.0 kg/(kg?d)]and DEX[10 mg/(kg?d)]for these two parameters. Conclusions The mechanism of arsenic trioxide antiasthma with arsenic trioxide can decrease EOS amount in bronchial submucosa and accelerate EOS apoptosis, and relieve bronchial inflammation in asthma. For inhaled lower dose arsenic trioxide or intraperitoneal injection with high dose arsenic trioxide ,the effect of EOS is equivalent. The antiasthma effect of inhaled lower dose arsenic trioxide[2.0 mg/(kg?d)]is equivalent to intraperitoneal injection higher dose[5.0 mg/(kg?d)],and may be safe comparatively. The mechanism of antiasthma by inhaled arsenic trioxide is the same with DEX.
