Tumor necrosis factor (TNF)-αis a pleiotropic inflammatory cytokine, which is produced chiefly by acti?vated macrophages. Two forms of TNF-α, soluble and transmembrane, can bind tumor necrosis factor receptor (TNFR) 1 or TNFR2, respectively. Recently, a concept has emerged that TNF-α/TNFR pathway plays an important role in the pathogene?sis of multiple sclerosis and remyelination. TNFR1 induces death of oligodendrocytes via death receptor-mediated apoptosis, which leads to demyelination or other neurodegenerative changes. However, TNFR2 has a positive effect on multiple sclero?sis. It facilitates the proliferation and differentiation of oligodendrocyte precursor cells, thus promoting remyelination.

Objective To summarize the clinical features,treatment and prognosis of bullous systemic lupus erythematosus (BSLE).Methods Clinical data were collected from 6 cases of BSLE between May 2009 and September 2015,and were analyzed retrospectively.Results Among the 6 patients,2 were male and 4 were female.The mean age of onset was 34 years.All the 6 patients presented with tense blisters and bullae arising on an erythematous base or normal skin,which were arranged in an annular pattern in 3 patients.The SLE Disease Activity Index (SLEDAI) score was ＞ 4 in all the 6 patients.Histopathological examination showed subepidermal blisters or fissures in all the patients.Direct immunofluorescence (DIF) revealed continuous linear deposition of immunoglobulin G (IgG),IgM and IgA in all the patients,linear deposition of C3 in 4 patients,and linear deposition of Clq in 2 patients at the basement membrane zone (BMZ).All the 6 patients were treated with oral glucocorticoids and hydroxychloroquine,and 2 patients were additionally treated with cyclophosphamide.During the follow-up period,adverse reactions to different extents were observed in the 6 patients.Conclusions BSLE mainly occurs in young and middle-aged people.Histopathologically,subepidermal blisters or fissures can be observed with linear deposition of IgG,IgM,IgA,or C3 along the basement membrane zone on DIF.

Objective:To investigate the antitumor effect of CpG-ODN combining non-replicating recombinant vaccinia virus in tumor immunotherapy.Methods: CpG-ODN and constructed vaccinia virus v△11?75 were combined to study the antitumor effects in the walker′s rat tumor model.Results: Recombinant vaccinia virus v△11?75 lost the replicating capacity on human cell line,143TK - cell.The genes between HindⅢ C & K fragment of vaccinia virus TianTan strain were deleted,verified with Southern-blot. In the Walker′s tumor model of Wistar rats,Combinational immunotherapy with CpG-ODN and non-replicating vaccinia virus-modified WRC256 oncolysates resulted in prolonged life span and reduced tumor hyperplasia. Conclusion: CpG-ODN can enhance the antitumor effects of non-replicating vaccinia virus-modified oncolysates,providing a new route of tumor therapy.

Objective: To investigate the diagnostic value of 64 multislice spiral CT (64-MSCT) and 1.5T MRI in nurseling with congenital vascular rings.
Methods:We retrospectively studied the diagnostic records of 64-MSCT and 1.5T MRI in 48 nurseling with congenital vascular rings. There were 42 cases received CTA, 12 received MRA and 6 received both CTA and MRA. We classiifed the types of vascular rings by Edwards sketch map of aortic arch embryonic development and trachea wrapping conditions. The diagnostic values of 64-MSCT and 1.5T MRI on vascular rings were compared.
Results: There were 25 patients with complete vascular rings including 3 of double aortic arch, 12 right aortic arch with left subclavian artery and patent ductus arteriosus (PDA), 9 combining with arterial ligament, 1 neck right aortic arch with left subclavian artery combining left PDA;and 23 patients with in-complete vascular rings including 2 pulmonary artery sling, 9 left aortic arch with right subclavian artery combining left PDA, 10 combining with arterial ligament, 1 right aortic arch with left subclavian artery combining right PDA, 1 with innominate artery compressed trachea. There were 32/48 patients combined with cardiac malformations, both 64-MSCT and 1.5T MRI may well reveal the composition and special relationship of vessel rings. The minimum intensity projection (MinIP) and air volume rendering (VR) of 64-MSCT may clearly display the morphology and development of trachea, image fusion technique could directly show the special relationships among vascular rings, trachea and esophagus. While 1.5T MRI was relatively poor to present tracheal image.
Conclusion: 64-MSCT could accurately and comprehensively display the special relationships among the vessels rings, trachea and esophagus;which was the best method for diagnosing the nurseling with vessel rings in clinical practice.

Objective To detect the levels and study the clinical significance of serum procollagen type Ⅰ amino-terminal propeptide (PINP) and β-C-telopeptides of type Ⅰ collagen (β-CTX) as bone turnover markers in recombinant human growth hormone (rhGH) treatment of prepuberty idiopathic short stature (ISS) children.Methods Forty patients of ISS (18 boys and 22 girls) had been collected and treated with GH 0.15 IU/(kg · d) injection every night.Serum levels of PINP,β-CTX,insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 3 (IGFBP3) were measured by electrochemiluminescence immunoassay in ISS before treatment and after 3,6 months,and they were also measured in 50 healthy children of the healthy control group,and the height,weight,body mass index,height standard difference score (HtSDS),bone age and growth rate were recorded.Results (1) In ISS group,the serum level of PINP[(479.51 ± 134.61) μg/L] was lower than that of the healthy control group [(651.31 ± 212.41) μg/L],the level of β-CTX[(0.84 ± 0.33) μg/L] was higher than that of the healthy control group [(0.50 ± 0.15) μg/L].The differences were statistically significant (t =2.276,-2.709,all P ＜ 0.05).(2) The serum levels of PINP and β-CTX had no significant difference in 18 boys and 22 girls before and after GH treatment (P＞0.05) of ISS.After 3 months of GH treatment,the serum levels of PINP[(736.15 ± 156.59) μg/L] and β-CTX [(1.08 ± 0.27) μg/L] were higher than those before treatment in 40 cases,and the difference was statistically significant (t =4.736,2.497,all P ＜ 0.05),as the increase of PINP was particularly significant.HtSDS (-2.95 ±0.43),compared with before treatment (-2.69 ± 0.58),was significantly different (t =2.714,P ＜ 0.05).However,after 6 months of GH treatment,the levels of PINP[(860.90 ±254.59) μg/L] and β-CTX[(0.94 ±0.32) μg/L] increased slowly (t =1.366,-0.831,all P ＞ 0.05).HtSDS (-2.51 ± 0.54) showed no significant difference (t =1.609,P ＞ 0.05) compared with 3 months of treatment.(3) The serum level of PINP was positively correlated with IGF-1 and IGFBP3 (r =0.636,0.673,all P ＜ 0.05),and there was no correlation with β-CTX (r =0.336,P ＞0.05).PINP and β-CTX had significant correlation with HtSDS (r =0.655,0.782,all P ＜ 0.05).Conclusions The serum PINP and β-CTX as bone turnover markers in serum can be used as one of the early supplementary indicators to predict GH response of ISS.

BACKGROUND:Systemic lupus erythematosus is a kind of heterogeneous disease, and the difference of clinical features may also be the risk factors of osteonecrosis besides of treatment with glucocorticoids according to the literature. However, it remains controversial on the risk factors of osteonecrosis in systemic lupus erythematosus patients.
OBJECTIVE:To systematical y review the major risk factors of osteonecrosis in the Chinese patients with systemic lupus erythematosus.
METHODS:The CNKI database, CBMdisc database and Wanfang database were retrieved for the published case-control study literatures on the risk factors of osteonecrosis in the Chinese patients with systemic lupus erythematosus. The literatures met the inclusion and exclusion criteria were included, and a Meta-analysis was conducted by RevMan 5.0 and Stata software. Then, the pooled odd ratio and 95%confidence interval of each risk factor were calculated.
RESULTS AND CONCLUSION:Ten case-control study literatures were included involving 332 cases in the case group and 986 cases in the control group. The pooled odd ratio and 95%confidence interval of each risk factor of osteonecrosis in the Chinese patients with systemic lupus erythematosus were as fol ows:Raynaud’s
phenomenon 3.28(1.69-6.38), dental ulcer 2.95(2.13-4.09), renal involvement 1.21(0.83-1.74), vasculitis 5.64(2.84-11.21), hyperlipidemia 5.11(3.10-8.42), anti-phospholipid antibody 2.32(1.49-3.61) and joints involvement
2.02(1.33-3.07). It has been clear that the glucocorticoids is an independent risk factor of osteonecrosis in the patients with systemic lupus erythematosus. However, it is not the one and only risk factor. The fol owing risk factors of
vasculitis, hyperlipidemia, Raynaud’s phenomenon, dental ulcer, positive anti-phospholipid antibody and joints involvement are the risk factors of osteonecrosis in the patients with systemic lupus erythematosus.
