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.

Descriptive analyses were used to classify therapeutic biologics by level of innovation,therapeutic category and the chemical na-ture of the drugs. The results showed that from 1996 the thera-peutic biologics entered the fast development period, especially from 2001 to 2005. The 125 therapeutic biologics focus on the treatment of tumor, immune system disease, endocrine and met-abolic diseases, blood system diseases, skeletal muscle system diseases. Antibody has become the dominant of therapeutic bio-logics. Antibody is widely used in the treatment of cancer, di-gestive diseases, immune diseases, respiratory diseases, urinary diseases, skeletal muscle diseases, etc.

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.

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.

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 investigate the effects of N-acetylserotonin (N-AS) on the expression of active caspase-3,Bcl-2 and Bax in rat retinas induced by retinal ischemia-reperfusion injury (RIRI).Methods Adult male Sprague-Dawley rats were randomly divided into the normal control group (6 cases),RIRI group (30 cases) and NAS group (30 cases),RIRI models in NAS group were established after giving NAS,the groups were sub-divided into 6 hours,12 hours,24 hours,48 hours and 72 hours group based on the time of RIRI.Morphologic changes were evaluated by HE staining.The expression of active caspase-3,Bcl-2 and Bax protein in the retina of rats was detected by immunohistochemistry.Results HE staining showed that the retinal structure in the normal control group was clear,and the cells in each layer were tightly packed;Each layer of retina was edema in the RIRI group after 6 hours and 12 hours,the edema gradually alleviated after 24 hours,the ganglion cells decreased gradually,the distribution was in disorder,with the prolongation of time,the retinal ganglion cells were defected;drug group of as Compared with RIRI group,the cell edema in the NAS group at 6 hours and 12 hours were obvious reduced,the cells in 24 hours,48 hours,72 hours group arranged regularly,the loss number of ganglion cells were reduced.The number of active caspase-3 positive cells in RIRI group increased at 6 hours after peffusion,the number was (561.15 ±37.19) cell ·mm-2,and reached the high level at 24 hours,the number was (1522.61 ±84.36) cell · mm-2,and then decreased gradually.The number of active caspase-3 positive cells in NAS group was significantly lower than that in RIRI group,the difference was statistically significant (all P ＜ 0.05).The expression of Bcl-2 positive cells in RIRI group began to decrease after 6 hours,and decreased to a low level at 24 hours,and the number of Bcl-2 positive cells in NAS group was significantly higher than that in RIRI group at each time point,the differences were statistically significant (all P ＜ 0.05).There were almost no Bax positive cells in the retina of the control normal group,and the Bax positive cells were found to be higher of the RIRI group at the 6 hours after RIRI,and reached the higher level at 24 hours,and decreased at 48 hours.The Bax positive cells of NAS group were significantly less than those in the RIRI group at different time points,and the differences were statistically significant (all P ＜0.05).Conclusion NAS can promote the expression of Bcl-2 protein in rat retina after RIRI,inhibit the expression of Bax protein,decrease the expression of active caspase-3 protein,alleviate cell apoptosis,and have neuroprotective effects.
