Objective To explore the immunomodulatory effects of seaweed polysaccharide(PSS)in aged mice induced by D-ga-lactose (D-gal).Methods D-gal was injected intraperitoneally to establish the aged mice model,meanwhile the aged mice was intra-gastricly administrated by PSS.Peritoneal macrophages were collected,and macrophage secretion of nitric oxide (NO),nitric oxide synthase (NOS)levels and expression levels of inducible nitric oxide synthase (iNOS)mRNA were detected.The spleen indexs of the agd mice were calculated,and effects of PSS on spleen microscopic structure of mouse were observed.The changes of spleen cell cycle in aged model mice were detected by flow cytometry assay.Results PSS could enhance macrophage synthesis of NO and NOS of the aged mice and up-regulate the expression of iNOS mRNA levels.And the spleen index of the aged mice increased obviously, the hyperplasia of spleen capsule was obvious.Moreover,PSS could increase the percentage of S phase and G2/M phase cells of the aged mice spleen.Conclusion PSS could enhance the immune function of aged mice induced by D-gal,which is worthy of further study,which development.

Rheumatoid arthritis (RA) is a kind of chronic, progressive, multiple, invasive autoimmune disease with two chief cclinical manifestations arthrosynovitis and ex-arthrosis, easy to occur in middle-aged women, also occur in children and the elderly, is characterized by progressive and break out repeatedly. RA pathogenesis is complex, there is no special treatment, used in treatment of R drug varied, new drugs and new therapies also emerge in endlessly, main including non-steroidal anti-inflammatory drugs (NSAIDs), slow action anti-rheumatism medicine (SAARDs), glucocorticoids (GCs), biological agent, traditional Chinese medicine and traditional Chinese medicine preparations, domestic market for rheumatoid main drug treatment are NSAIDs, SAARDs, GCs, traditional Chinese medicine and traditional Chinese medicine preparations. Traditional Chinese medicine and traditional Chinese medi- cine preparations for the treatment of RA have its unique advantages, show the characteristics of overall adjustment, multi-level and multiple targets, and also can alleviate and against side effects of western medicine. In recent years, more and more get people's atten- tion. This paper reviewed the research progress and treatment features of commonly used therapeutic agents for the treatment of RA in recent years, which provides reference and basis for future medicine anti-RA.

AIM: To study the protective effect of bone marrow stromal cells (MSCs) on ischemia /reperfusion hippocampal slices. METHODS: Ischemia/reperfusion models of hippocampal slices from newborn rats were established. MSCs obtained from adult bone marrow were cultured, isolated and purified. Cell death was assessed using propidium iodide fluorescence. And brain-derived neurotrophic factor (BDNF) expression in MSCs was determined by immunocytochemistry and Western blot. RESULTS: Maximal dead cells appeared in hippocampal slices 3 to 7 days after reperfusion. When the slices were co-cultured with MSCs, only a few cells were dead. The protective effect of MSCs on the slices was diminished significantly when anti-BDNF antibody was added to the medium. The protein of BDNF was faintly expressed in MSCs under normal conditions. When MSCs were co-cultured with ischemia /reperfusion hippocampal slices, the expression of BDNF in MSCs was increased gradually especially when co-cultured for 3 to 7 days. However, MSCs co-cultured with normal hippocampal slices expressed BDNF at a lower level at any times of co-culture. CONCLUSIONS: In an in vitro model of simulated ischemia, MSCs reduce cell death. Ischemia/reperfusion hippocampal slices co-cultured with MSCs promote the expression of BDNF in MSCs, which in turn protect the ischemic neurons.

Pancreatic neuroendoerine tumors (PNET) is a complicated and heterogeneous group of neoplasia,and the incidence of PNET is growing rapidly recently.The current study on PNET lags behind what is known of other pancreatic tumors.Therefore,understanding of the molecular pathology is important for improving the early diagnosis,treatment and prognosis.With the development of molecular biology,there are already several potential targets proved to have application role in treatment of PNET.Here,the authors present the current knowledge about the molecular alterations of PNET.

Objective To explore the relationship between sex hormone-binding globulin (SHBG) of gestational diabetes mellitus ( GDM ) pregnant women with well-controlled glucose and pregnancy outcomes. Methods Two hundred and fifty-one GDM pregnant women of 24 - 28 weeks in Shengjing Hospital of China Medical University were recruited from Mar. 2005 to Mar. 2010. Two hundred and sixteen cases of GDM with well-controlled glucose were defined as glycemic satisfied group, and they were treated by diet therapy ( 169 cases) or insulin therapy (47 cases) . Thirty-five cases with unsatisfied glucose were defined as glycemic unsatisfied group. One hundred and ninety-two healthy pregnant women of 24 - 28 weeks were defined as healthy control group. Serum SHBG and homeostasis model analysis of insulin resistance ( HOMA-IR) at 24 - 28 weeks and above 36 weeks were measured. GDM was diagnosed bytwo-step method according to the National Diabetes Data Group ( NDDG) criteria. The pregnancy outcomes and complications of the three groups were recorded. Results ( 1 ) Comparison of pregnancy outcomes and complications: glycemic satisfied group was less likely to develop hypertensive disorders in pregnancy ( 10. 6% ) , premature birth(8. 3% ) ,large for gestational age ( LGA) (8. 8% ) , neonatal asphyxia(3. 7% ) and neonatal hypoglycemia ( 2. 3% ) compared to glycemic unsatisfied group ( 42. 9% , 34. 3% , 31. 4% , 22. 9% and 11. 4% ,respectively). And the difference was statistically significant (P ＜0. 05 or P ＜0. 01). There was no significant difference for incidence of polyhydramnios, pueperal infection, postpartum hemorrhage, neonatal hyperbilirubinemia between the two groups ( P＞ 0. 05 ) . When compared to healthy control group(7. 3% ,2. 1% ,4. 2% ,2. 1% and 1. 6% ) ,no significant difference was found for incidence of premature birth( 8. 3% ) , pueperal infection ( 3. 2% ) , postpartum hemorrhage (5. 1% ) , neonatal asphyxia (3. 7% )and neonatal hypoglycemia(2. 3% ,P ＞0. 05). (2) Comparison of results of 24 - 28 weeks and above 36 weeks: serum SHBG of glycemic satisfied group [( 384 ± 88 ) , (457 ± 48 ) nmol/L]was significantly higher than that of glycemic unsatisfied group[(313 ±45) ,(401 ±73) nmol/L];HOMA-IR of glycemic satisfied group (5. 3 ±1.1,5.5 ±1.1) was significantly lower than that of glycemic unsatisfied group (7. 0 ± 1. 3 ,7. 6 ± 1. 7 ; P ＜ 0. 01). Serum SHBG of glycemic satisfied group was significantly lower than that of healthy control group [( 492 ± 95 ) , (565 ± 40 ) nmol/L]; and HOMA-IR of glycemic satisfied group(5. 3 ± 1. 1,5. 5 ± 1. 1) was significantly higher than that of healthy control group (3. 6 ±0. 6,3. 9 ± 0. 5 ;P ＜ 0. 01 ) . FPG of glycemic satisfied group [( 5. 84 ± 0. 28 ) , ( 5. 16 ± 0. 13 ) mmol/L]was significantly lower than that of glycemic unsatisfied group [(6. 13 ± 0. 16 ) , ( 5. 68 ± 1. 14) mmol/L; P ＜ 0. 01]. FINS of glycemic satisfied group [( 20. 4 ± 2. 1 ) , ( 24. 1 ± 4. 2 ) mmol/L]was significantly lower than that of glycemic unsatisfied group [(24. 7 ± 4. 5 ) , ( 29. 9 ± 2. 7 ) mmol/L; P ＜ 0. 01]. ( 3 ) Correlation analysis. Between 24 - 28 weeks, SHBG was negatively correlated with HOMA-IR in the three groups ( r = -0. 952, P ＜0. 01) ; and SHBG was negatively correlated with HOMA-IR in glycemic satisfied group ( r = -0. 903, P ＜0. 01). Conclusions Well-controlled glucose can not completely improve maternal and fetal outcomes of GDM pregnant women. High insulin resistance and low serum SHBG can influence pregnancy outcomes.
