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 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.

To investigate the effect of pancreatic elastase on diabetic nephropathy,104 cases of type Ⅱ diabetic patients were selected as control group and group treated with elastase separately for a course of 6 months.The results showed that pancreatic elastase reduced microproteinuria significantly,especially mi- croalbuminuria and microtransfer rrinuria which reflect the glomerular filtration rate.It was concluded that elastase could improve early diabetic nephropathy and might have some protective effect as well.At the same time,elastase had some good effect on lipid and lipoprotein metabolism.

Objective:To investigate the clinical characteristics and prognosis of secondary hemophagocytic syndrome (HPS) in adults.Methods:The clinical data of 43 adult patients with primary secondary HPS in Mianyang Central Hospital of Sichuan Province from January 2014 to June 2020 were retrospectively analyzed. The patient's clinical manifestations and biochemical indicators were summarized. The clinical characteristics of patients between high-level ferritin (≥5 000 μg/L) group and low-level ferritin (<5 000 μg/L) group, lymphoma-related HPS group and infection-related HPS group were compared. Logistic regression model was used for multivariate survival analysis.Results:All patients had fever as the main complaint, and infections were manifested at the onset or during treatment. In all patients, 88.4% (38/43) had hemophagocytosis in the bone marrow; 88.4% (38/43) had varying degrees of cytopenia; 36.6% (15/41) had reduced fibrinogen [median value 0.93 g/L (0.50-1.35 g/L)]; 76.7% (33/43) had elevated aminotransferase. Compared with the low-level ferritin group (19 cases), the high-level group (21 cases) had a lower proportion of monocytes (0.081±0.040 vs. 0.163±0.076, P = 0.016), the incidence of fibrinogen reduction and the incidence of aminotransferase elevation were high [60.0% (12/20) vs. 11.1% (2/18), P = 0.002; 95.2% (20/21) vs. 52.6% (10/19), P = 0.006]. Compared with infection-related HPS patients, lymphoma-related HPS patients had a higher incidence of lymphadenopathy [72.7% (16/22) vs. 27.8% (5/18), χ2 = 8.021, P = 0.005] and a lower incidence of aminotransferase elevation [59.1% (13/22) vs. 94.4% (17/18), χ2 = 4.848, P = 0.028]. Multivariate analysis showed that the high proportion of neutrophils ( OR = 0.886, 95% CI 0.786-0.998, P = 0.046) and high-level albumin ( OR = 0.376, 95% CI 0.156-0.907, P = 0.030) after treatment were protective factors for survival of patients. Conclusions:Among adult patients with primary secondary HPS, the proportion of monocytes in patients with ferritin ≥5 000 μg/L is low, and liver damage and fibrinogen reduction are more likely to occur. Lymphoma-related HPS patients are more likely to have lymphadenopathy, and infection-related HPS patients are more likely to have liver damage. After treatment, a low proportion of neutrophils and hypoproteinemia indicate a poor prognosis in adult patients with secondary HPS.

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.
