Objective To investigate the protective effect of methylene blue (MB) on blood-brain barrier (BBB) injury after focal cere-bral ischemia-reperfusion in rats. Methods 18 male Sprague-Dawley rats were randomly divided into sham-operated group (n=6), model group (n=6) and MB treatment group (n=6). The left middle cerebral arteries were occluded for 1 hour and reperfused. MB was infused intra-venously immediately after reperfusion (3 mg/kg) and again 2 hours post-reperfusion (1.5 mg/kg), while normal saline was administered in the model group. The sham-operated group was treated as same as the model group without occlusion and infusion. HE staining was used to observe the histological injury in the cortex around the infarcted region 47 hours after reperfusion, while albumin immunohistochemistry was used to evaluate the permeability of the BBB, and immunohistochemistry and double immunofluorescence staining were used to exam-ine the expressions of glial fibrillary acidic protein (GFAP) and aquaporin-4 (AQP-4). Results HE staining showed that cells and blood ves-sels were not intact in the cortex around the infarcted region in the model group and they were better in the MB treatment group. The expres-sions of the albumin, GFAP and AQP-4 were higher in the model group than in the sham-operated group (P<0.01), and were lower in MB treatment group than in the model group (P<0.05). The double immunofluorescence staining showed the colocalization of GFAP and AQP-4 in the astrocytes. Conclusion MB may ameliorate the BBB disruption induced by focal cerebral ischemia-reperfusion through reducing glio-cyte proliferation and down-regulation of AQP-4 expression in rats.

Objective To better understand the clinical features and the diagnosis of monoclonal gammopathy of undetermined significance (MGUS) associated with systemic lupus erythematosus (SLE).Methods A case of MGUS with SLE were described including clinical manifestations and pathologic data.Literatures were also reviewed.Results The patient was admitted because of proteinuria.Laboratory findings showed monoclonal gammopathy.However,both bone marrow exam and iconography showed no signs of multiple myeloma.Lupus nephritis Ⅳ + Ⅴ was proved by kidney biopsy.Prednisone and tacrolimus were used with significant clinical improvement.Conclusion MGUS associated with SLE is not rare.MGUS criteria based on 2003 international MM working group should be used to differentiate MGUS from MM.Monoclonal protein level,plasma cell in bone marrow and free light chain are risk factors for MM progression.Treatment is based on lupus disease activity and organ damage severity.

Objective To analyze the clinical effects of individualized comprehensive physiotherapy interventions for temporomandibular disorders (TMD).Methods Data of 307 patients with TMD treated between April 2011 and March 2012 in the authors' department were collected and reviewed.All the patients were treated with individualized comprehensive physiotherapy approach based on the patient's category in research diagnostic criteria for TMD (RDC/TMD),such as patient education,ultrashort-wave diathermy,ultrasound therapy,soft tissue massage,joint mobilization and stabilization exercise.The treatment was administered for 3 weeks.The baseline and endpoint outcome assessment measures were maximum active mouth opening (mm),visual analogue scale (VAS) score and joint clicking (100％ before treatment).Results At the end of treatment,the patient's maximum active mouth opening [(36.95 ± 6.59) mm],VAS score (1.21 ± 0.62) and joint clicking [(29 ± 17) ％] improved significantly (P ＜ 0.05) compared to baseline.Conclusions Individualized comprehensive physiotherapy interventions can improve symptoms of TMD,such as joint clicking,pain,limited mouth opening.

Objective To detect the serum prohibitin protein(PHB)level in children with renal interstitial damage and analyze the correlation between PHB and renal interstitial fibrosis(RIF). Methods Serum PHB protein levels were determined by Western blot analysis in 36 children with kidney diseases,and 30 healthy children were studied as control. Levels of BUN,Scr,and urinary microprotein series(including ALBU/Cr,NAGU/Cr,IgG U/Cr,α1-MU/Cr)were studied by automatic biochemical analyzer. Renal interstitial damage was semiquantitatively graded according to Katafuchi's method. The correlation between serum levels of serum PHB protein and those of BUN,Scr as well as urine microprotein were analyzed. Results Serum PHB protein was positive in children with diverse kidney diseases however it was negative in the normal controls(P ＜ 0.05). Serum PHB levels were significantly higher in children with proliferative glomerulonephritis than those with non-proliferative glomerulonephritis(P ＜ 0.05). Statistical analysis indicated that serum PHB levels positively correlated with the degree of tubulointerstitial lesions(r ＝ 0.868,P ＜ 0.001)as well as the glomerular injuries(r ＝ 0.753,P ＜ 0.001). And,serum PHB levels were also positively correlated with urinary microprotein including NAG(r ＝ 0.586,P ＜ 0.001)and IgG(r ＝ 0.341,P ＜ 0.001). Conclusions Serum PHB levels were significantly increased in children with kidney diseases and were positively correlated with the degrees of renal interstitial damage,suggesting that PHB might be a potential clinical marker for detecting tubulointerstitial lesions.

Objective:To identify the normal position of the root tips of lower premolars, first and second molars, the distances through 3-D reconstruction in 100 cases of general population were measured. Methods: The three distances were measured from 100 cases over 17 years old, divided by gender: 1. The distance of Mandible of the Centre (M) under the jaw to the lower edge of the next point (L);2. The distance of Mandible of the Centre (M) and M points to the horizon at the same point of the buccal (O);3. The distance of Mandible of the Centre (M) and M to the point in the same horizontal line at the side of the tongue(I). Results: The second premolar root tip of the jaw bone under the margin of the thick wall, the wall thickness of tongue in cheek bone lateral side of the wall in the first and second molars, the lower edge of the mandible bone wall, the tongue side of the wall, cheek bone side walls were thicker through 3-D reconstruction measurement than in normal way.Cheek bone was much thicker than the tongue side of the wall. Conclusion: The way of identifying the normal lower in the second premolar and the first and second molar root tip through the three distances by 3-D reconstruction will give us lots of help, such as: Orthognathic operation of the mandible sagittal split SSRO, scaling of cysts, planting of a certain theoretical basis for scientific research and teaching to provide a realistic and practical method.

Neuroblastoma(NB),the common extracranial solid tumor of childhood,is thought to derive from neural crest cells.In disialoganglioside (GD)2 is highly expressed on NB,whereas GD2 expression is weak and restricted to the central nervous system,peripheral pain fibers and skin melanocytes.Therefore,GD2 is an ideal antigen target for immunotherapy of NB.The research progress on GD2 as target for immunotherapy of NB was reviewed.
