SUMMARY Marginal zone B-cell lymphoma of the pulmonary mucosa-associated lymphoid tissue type (pulmonary MALT-MZL), a common kind of primary pulmonary lymphoma, is rare in pulmonary malignant tumors. One patient in our hospital was diagnosed by bronchoscope and the literatures on the subject were reviewed. The patient presented with periodical fever, cough and chest pain, and antibiotic therapy had no use. Chest CT scan showed the consolidation of right middle lobe and left lower lobe with CT angiogram signs, air bronchograms and distended bronchi. Pleural effusion in the left thorax mainly consisted of monocytes. Monoclonal protein was found in the electrophoresis of serum protein. Bronchial stenosis and swollen mucosa were seen with bronchoscope. The tissue section of transbronchial lung biopsy (TBLB) specimens showed diffusedly infiltrated small lymphocytes and a lymphoepithelial lesion. CD20 was positive and CD3, CD5, CD10, CD21, CD23, bcl2, bcl6 were negative in immunohistochemical stain. The clinical manifestations of pulmonary MALT-MZL are nonspecific and misdiagnosis is common, Appropriate invasive biopsy procedures are necessary for early diagnosis. Presentations such as periodical fever, distended bronchi in pulmonary consolidation, monoclonal protein might indicate diagnosis. Treatment includes surgical resection, radiotherapy and chemotherapy. Pulmonary MALT-MZL belongs to inert lymphoma and prognosis is relatively good.

Objective:To observe the effects of All-trans retinoic acid (ATRA) on the immune functions of AChR-specific lymphcytes via in vitro assays,and investigate the possibility of ATRA in the clinical treatment of myasthenia gravis (MG).Methods:CFA control group and EAMG experimental rats were established to obtain single lymphocytes suspension and cells were followed by AChR97-116 peptide with or without ATRA stimulation for 72 h,and then viable cell population,cell apoptosis,cell cycle and the distribution of Th cells were determined by flow cytometry.CCK-8 assay was selected to evaluate the effects of ATRA on proliferatory ability of lymphocytes.ELISA was used to detect the antibody secretion of B cells affected by ATRA.Results:Compared with CFA group,lymphocytes obtained from EAMG rats had higher ratios of living cells,and this ratio was obviously decreased after ATRA treatment,P＜0.001.Different concentrations of ATRA promoted the apoptosis of AChR-specific cells (P＜0.001),and the promoted effects were ATRA dose-dependent,however,cell cycles were not changed.ATRA markedly inhibited the proliferation of cells from both CFA and EAMG groups,moreover,AChR-specific cells were more sensitive to ATRA treatment (P＜0.01) than that of cells from CFA rats (P＜0.05).The ratio of AChR-specific CD4+T cells was reduced by ATRA (P＜0.01),and ATRA incubation significantly promoted the percentages of Th2,(PCD4+-4IL-4+＜0.001),Treg (PCD4+-Foxp3+＜0.001) cell types,but markedly inhibited the percentages ofThl7 (PCD4+-IL-17+＜0.05),Thl (PCD4+-IFN-γ+＜0.001) cells.ELISA data showed us that ATRA obviously down regulated the antibody secretion of AChR-specific B cells,P＜0.01.Conclusions:ATRA not only inhibited the functions of AChR-specific T cells,but also suppressed the roles of AChR-specific B cells,predicating a therapeutic effect of ATRA on myasthenia gravis therapy.

BACKGROUND:cAMP response element binding protein (CREB) is a key protein of memory, which is closely related to long-term memory. It wil provide a new way for the treatment of hypoxic ischemic brain damage (HIBD) to study the effects of dental pulp stem cel s transplantation on the long-term behavior and CREB protein via the lateral ventricle in neonatal HIBD rats. OBJECTIVE:To observe the changes in long-term behavior and CREB protein expression in neonatal HIBD rats after human dental pulp stem cel transplantation, thereby providing scientific evidence for clinical treatment of neonatal HIBD. METHODS:Thirty-six healthy 7-day-old Sprague-Dawley rats were randomly divided into normal, HIBD and cel transplantation group. The hypoxic ischemic brain damage models were established in the brain damage and cel transplantation groups. Twenty-four hours after HIBD, human dental pulp stem cel s were injected into the left lateral cerebral ventricle of rats in the cel transplantation group, total y 3×106 living cel s. Equal volume of normal saline was injected into the left lateral cerebral ventricle of rats in the normal control and HIBD groups. RESULTS AND CONCLUSION:The average time to seek water, the average escape latency and escape distance of the human dental pulp stem cel s group were significantly shorter than those of hypoxic ischemic brain injury group (P<0.01), but longer than those in the normal group (P<0.01). Nissl staining showed that the cel s in the hippocampal CA1 region in human dental pulp stem cel s group were more regular, the number of cel s was significantly higher than that of hypoxic ischemic brain injury group, but stil significantly less than that in the normal group (P<0.05). Immunohistochemical staining results showed that the number of CREB positive cel s in human dental pulp stem cel s group was significantly higher than those in HIBD group, but stil significantly less than those in the normal group (P<0.01). It is suggested that human dental pulp stem cel s transplantation could promote the expression of CREB protein in the hippocampal CA1 region, to improve the long-term learning and memory ability of hypoxic ischemic neonatal rats, and thus repair HIBD.

Objective To explore the effects of andrographolide(AP),extracted from the traditional Chinese herb Andrographlis paniculata(AP),on injury induced by radiation exposure.Methods Sixty male rats were randomly divided into 4 equal groups and irradiated with 60Co γ-rays at the doses of 1,2,and 4 Gy,respectively:low dose AP group(intragnstrically administered with AP at the dose of 100 ms/kg daily for 10 d before irradiation),and high dose AP group(intragastrically administered with AP at the dose of 200 ms/kg daily for 10 d before irradiation),model group(administered with the same volume of normal saline instead of AP for 10 d before irradiation),and control group(irradiated only at 3 different doses).One day after irradiation all rats were killed with their livers being fixed to make paraffin section.The morphological feature was observed under light microscope after HE staining,and the cell apoptosis was detected by TUNEL technology.Results Compared to the control and model groups,the pathological changes of liver were significantly gentler in the AP treatment groups.The apoptosis rates of the liver cells of all the AP sub-groups were significantly lower than those of the control and model subgroup(t=2.19-4.80.P<0.05).Conclusions AP might have prevention effect against radiation exposure.
