Objective:To explore the clinic and pathologic characteristics of primary breast lymphoma(PBL) for its diagnosis and treatment.Methods: Five cases of PBL that has been diagnosed during 1998-2005 were analyzed.Results: One patient died 1 month after her final diagnosis.Tow patients have survived 4 and 3 years,respectively,after radical operation plus chemotherapy,although inguinal lymphatic metastasis was found in the later one 2 years after her operation.Another two patients have been accepting chemotherapy for 3 months after their local resection.Conclusion: PBL is diagnosed basically by methods of pathology and immunohistochemistry,and treated mainly by chemotherapy combining with other therapies.

Objective To investigate the safe model to prevent and treat complications caused by various artificial liver support system(ALSS).Methods The complications in 191 patients with severe hepatitis during the ALSS(Including plasma exchange、plasma exchange associated with continuous venovenous hemofiltration、plasma exchange associated with hemodiafiltration、plasma exchange associated with plasma absorption、molecular absorbents recycling system) treatment were observed and analyzed. Results During the treatment 287 episodes occurred and the rate of complications was 50.44%(287/569).The clinical manifestation included rash,numbness/tetany,hypotension,blood clotting in the channel,chest distress, disequilibrium syndrome,errhysis on dwell catheter,effusion on dwell catheter.75.61% of these complications was caused by plasma exchange.The rate of complications was the lowest during the treatment of plasma exchange associated with hemodiafiltration.All of these complications got better after prompt sypotomatic therapies were taken.Conclusions Although the rate of complications was high during the treatment of ALSS,all of the complications got better after prompt sypotomatic therapies were taken.This therapeusis must be performed by intensive care.It is more safe than others during the treatment of plasma exchange associated with hemodiafiltration.

0.05).Conclusions HPC has protective effect on neonatal rats with cerebral hypoxia-ischemia,but it does not have obvious effect on NGB.

Objective To investigate the trend of developmental expression of GluR2,subtype of alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid(AMPA) receptor and synaptophysin(SYP) in the rat cochlear nucleus(CN) in different developmental stages,and explore the association of GluR2 expression with the development of synapse. Methods SD rats of 2,3,4,6,8 and 10 weeks old were selected,the expression of GluR2 and SYP in CN was detected with immunofluorescence histochemical method,and the association of them was explored. Results GluR2 expression was observed in all the neurons of CN in each postnatal groups.The expression was relatively weaker in the second and third week,became denser in the fourth week,reached the peak in the sixth week and then sharply decreased to the weakest in the tenth week.The expression of GluR2 was denser at granular cell layer,while weaker at molecular layer and multipolar cell layer in the dorsal CN.SYP expression was detected in all the neurons of CN in each postnatal groups.The expression was weakest in the second week,significantly denser in the fourth week,reached the peak in the sixth week,was then sharply decreased and stably maintained. Conclusion The expressions of GluR2 and SYP in the postnatal rat CN exhit an equally age-dependent tendency.The expression of GluR2 in the CN may be associated with the the maturation and function development of the CN.The different expression and distribution of GluR2 and SYP in the rat CN of different developmental stages may be involved in the development and plasticity of auditory center.

Objective To observe the protection effects of sodium ?-aescinate(SA) on the nervous function in the rats with early spinal cord injury(SCI). Methods One hundred and twenty SD rats were randomly divided into four groups(n=30).Rats in the blank control group were performed laminectomy only,while those in the other three groups were injured at the level of Tl1 spinal segment by Allen's weight drop method(10 g ?10 cm) and immediately intraperitoneally given normal saline(5.0 mg/kg)(control group), SA(5.0 mg/kg)(SA group) and methylprednisolone(100 mg/kg)(MP group) once daily,respectively.After 8 h,24 h,96 h,7 d and 14 d,spinal cord function change of posterior limb were determined with Rivlin method.The rats were sacrificed and the injured segments were resected for pathological analysis. Results As time prolonged,the rehabilitation of spinal cord function with various degree could be observed in each group.Function rehabilitation was found among the rats in the control group,SA group and MP group 96 h after injury,and more rehabilitation was gained later in the latter two groups,while that was not the case in the control group.Rats in the SA and MP group gained more significant rehabilitation than those in the control group(P0.05).It was revealed by pathological analysis that no necrotic neurons was found in the blank control group,and the necrotic neurons in the SA group and MP group were significantly less than the control group at the same time points(P

To state the importance of scientific research capability and general practitioners training for the poor scientific innovation conditions of general practitioner standardization training by the analysis of several ways to improve the scientific research capacity and the probe of the impact on strengthening the consciousness of scientific research to help general practitioner to better work in the areas of primary care and public health.

Objective To compare the effect of repairing large perimembranous ventricular septal defect (VSD) with a new continuous stitching and two classical methods. Methods From January 2005 to January 2008,321 cases with VSD were operated. All the cases were divided into 3 groups according to operational way, with discontinuous stitching in group A (70 cases), continuous stitching in group B(116 cases),new continuous stitching in group C (135 cases). All the patients were total corrected with hypothermic cardiopulmonary bypass. Results Group C had the shortest cardiopulmonary bypass and aortic cross-clamp times [(48 ± 36) min and (26 ± 18) min]among the three groups (P < 0.05). Group C had not residual shunt and incidence rate was lowest among the three groups (P < 0.05). Temporary second degree auriculo-ventricular bolck (AVB) was found in the early stage and no third degree AVB among the three groups. Tricuspid regurgitation was higher in group A,but there was no significant difference between group B and group C. Follow-up was completed in a duration of 1-3 years and all the cases had a good health after discharged. Conclusions The new continuous stitching method has short eardiopulmonary bypass and aortic cross-clamp times. It has fewer residual shunt than other two classical methods and has no evidence of higher AVB occurrence.

Objective To assess the effect of peroxisome proliferator-activated receptor γ (PPARγ) agonist on prostate epithelial cells in vitro.Methods The expression of peroxisome proliferator-activated receptor γ(PPARγ) was studied by immunocytochemistry and immunofluorescence study.The RWPE-1 human prostate epithelial cell line was treated with PPARγ agonist rosiglitazone 100 μmol/L for 48 h.Analysis of apoptosis was performed by Caspase 3/7 activity assay.Mitochondria depolarization was measured by using the potential-sensitive color,JC-1.The expression of apoptosis-related proteins-Bax was investigated by immunohistochemistry.Results PPARγ mainly located in nucleus and perinucleus.RWPE-1 cell line treated with PPARγ agonist rosiglitazone showed higher Caspase 3/7 activity (10636±1032 RLU) than in control (5936±620 RLU),P＜0.01 and significantly upregulated Bax level (8250±694 vs.6017±563)than in control group,P＜0.01.In addition,mitochondrial membrane potential was depolarized in rosiglitazone treated cells.Conclusions PPARmay play important roles in the pathophysiology of BPH.The mechanism might be that PPARγ regulates cell apoptosis.It is suggested that the mitochondrial and Bax pathway might be involved in signaling PPARγ induced cell apoptosis.
