AIM:To improve accuracy of the diagnosis of primary conjunctival masses(PCM) through analyze the clinicopathological characteristics and pathogenic causes of 422 cases of PCM.METHODS:Clinical manifestations, histological characteristics and immunopheno types were reviewed.Relevant literatures were reviewed.RESULTS:Benign conjunctival masses were 403 cases (95.5%).Those included masses from squamous cell papilloma (71 cases, 17.6%), conjunctival cyst (68 cases, 16.9%), inflammatory masses (62 cases, 15.4%), pigmented nevus (60 cases, 14.9%), lipoma (58 cases, 14.4%).Malignant conjunctival neoplasms were 19 cases (4.5%).Those included tumors from B Cell Lymphoma (6 cases,31.6%), melanoma (6 cases,31.6%), and squamous cell carcinoma (5 cases, 26.3%).Different types of primary conjunctival masses were induced by the same cause.CONCLUSION:The pathological types of primary conjunctival masses are various and the majority of which is benign.For the diagnosis of primary conjunctival masses, morphological analysis, immunohistochemical examination shoud be combined to increase the diagnostic accuracy and decrease misdiagnosis rate.

Objective To predict the epitopes of Mycobacterium tuberculosis Rv2657c protein, to understand its immunogenicity Methods The T?cell and B?cell epitopes of Mycobacterium tuberculosis Rv2657c protein were predicted by DNAStar software package. The homology of Rv2657c amino acid sequence with the human protein sequences was prepared using Blast method, then the CTL epitopes were predicted using SYFPEITHI supermotif method, BIMAS quantitative motif method and NetCTL prediction method, and the Th epitopes were predicted by RANKPEP and SYFPEITHI supermotif prediction method. Results The prediction using DNAStar software package showed that Rv2657c protein had 5 B?cell epitopes and 6 T?cell epitopes. The protein had 6 CTL epitopes and there were 38 Th epitopes. Conclusion Rv2657c protein has both B?cell epitopes and T?cell epitopes. It may be a candidate target antigen for the studies of vaccine and diagnosis of tuberculosis.

·AIM: To evaluate the function of primary human corneal endothelial cells(HCEC) serving as immunological cells. ·METHODS: Expression of HLA-DP, -DQ, -DR, CD40, CD80, and CD86 was determined by immunohistochemical methods. Meanwhile, purified peripheral blood mononuclear cells(PBMC) were cocultured with primary HCEC which were pre-treated with and without γ-IFN respectively; activation of lymphocytes was determined by FACS analysis.·RESULTS: In coculture system, T lymphocyte was activated by primary HCEC, HLA-DP, -DQ, -DR and CD40 expression were increased by γ-IFN induction. Costimulatory molecular CD80 was shown on the endothelial cells. ·CONCLUSION: Primary HCEC were assumed to be involved in the corneal transplantation rejection process as potential antigen presenting cells(APC).

Objective To evaluate the potential effects of RS504393, CC chemokine receptor (CCR) 2b and CCR1 antagonist, on LPS-induced acute lung injury (ALI) and to investigate the underlying mechanisms. Method A549 cell line was stimulated with LPS (10 μg/mL) and then treated with RS504393 (10 μg/mL) for 6 hours. ALI model was established with intranasal administration of LPS (5 mg/kg) in C57BL/6J mice. RS504393 (5 mg/kg) was administered 30 min before LPS dripped nasally. IL-8, IL-1β, plasminogen activator inhibitor (PAI)-l,monocyte chemoattractant protein (MCP)-2,and the expressions of CCR1 and CCR2b were studied by using Realtime-RT-PCR, ELISA and cyto-flowmetry. Results In A549 cell line treated with RS504393,the expressions of CCR1, CCR2b and IL-8 were significantly inhibited after LPS stimulation. In rats with LPS-induced ALI, treatment with RS504393 significantly protected mice against lung injury by attenuating influx of leukocytes and protein into bronchoalveolar space and by lessening pathological changes of lung. Treatment with RS504393 down-regulated IL-1β and PAI-1 expressions in bronchoal veolar lavage fluid (BALF) and lungs at mRNA and protein levels along with up-regulation MCP-2 expression compared to rats of vehicle-treated groups. Conclusions CCR2b and CCR1 play pivotal roles in the development of ALl,and RS504393 as a antagonist can halt the development of ALI.

BACKGROUND: Cervical spinal cord injury without radiographic abnormality (SCIWORA) is a special type of spinal cord injury. Because of the particularity of children in the period of growth and development on the aspects of anatomy and biomechanics, their injured mechanism and therapeutic method differ from those of adults.OBJECTIVE: To explore clinical feature and therapy of first-episode cervical SCIWORA in children.DESIGN: Retrospective analysis and self pre-and post-control observation.SETTING: Department of Spine Surgery, Second Affiliated Hospital,Harbin Medical University.PARTICIPANTS: Totally 14 patients with cervical SCIWORA, who were treated at the Departmentof Spine Surgery, Second Affiliated Hospital,Harbin Medical University between June 1997 and June 2003. Inclusive criteria: ①patients who had dysfunction of sensation, exercise and sphincter to different degree in clinic, ②patients who had no fracture dislocation after cervical vertebra X-ray plain film and MRI examination. The MRI examination showed the sign of spinal cord injury. T1WI spinal cord became thick. T2WI distributed at strip-shape high-signal region along spinal prosenchyma and spread upward and downward. There were 3 patients with complete spinal cord injury and 11 patients with incomplete spinal cord injury, among the patients with incomplete injury, there were 6 patients with central cord syndrome (CCS), 3 with Brown-Sequard syndrome and 2withfrontal spinal cord injury syndrome.METHODS: Retrospective analysis was performed in 14 children patients with cervical SCIWORA. Thirteen patients were not treated with operation and one patient was treated with cervical posterior atlantoaxial fusion. MAIN OUTCOME MEASURES: ASIA grading before and after treatment in patients.RESULTS: There were 1 dead patient and 13 cases with 3-year follow up averagely. Three patients were with insignificant amelioration, and others had recovery of limb function to different degree. According to ASIA grading standard, before treatment there were 3 cases in A grade, 5 cases in B grade, 5 cases in C grade and 1 case in D grade, and after treatment there were 1 case recovering to B grade, 2 cases to C grade, 5 cases to D grade and 2 cases to E grade.CONCLUSION: Restoration of neurofunction of children with cervical SCIWORA has closely correlation with degree of primary injury of spinal cord. Most of the patients were not treated with operation, and those with obviously instable cervical vertebra can be treated with operation.

Objective To investigate the influence of Siraitia Grosvenori and Rehmannia Glutinosa on the Hematopoietic stem cells proliferation and function .Methods Cells from the peripheral blood , spleen and bone marrow of mice were stained with indicated antibodies , and analyzed by flow cytometry .Mice were divided 3 groups:control group, Siraitia Grosvenori treatment group and Rehmannia Glutinosa treatment group .After 4.5Gy IR treatment, mice divided 4 groups: control group, 4.5Gy IR treatment and feed with normal food, 4.5Gy IR treatment and feed with Siraitia Grosvenori and 4.5Gy IR treatment and feed with Rehmannia Glutinosa for 1 month.Results Mice fed with Siraitia Grosvenori and Rehmannia Glutinosa decreased the percentage of B cells and increased the percentage of M cell .For HSCs, the number of HSCs was increased , especially the number of LT-HSCs.After 4.5Gy IR treatment, mice fed with Siraitia Grosvenori and Rehmannia Glutinosa increase the number of HSCs , and increased the percentage of M cells . Conclusion Siraitia Grosvenori and Rehmannia Glutinosa promote the hematopoietic stem cells and progenitor cells proliferation and function and recover the damage that caused by IR treatment .
