This study investigated the effect of arctigenin (Arc) on the cell activation, cytokines expression, proliferation, and cell-cycle distribution of mouse T lymphocytes. Mouse lymphocytes were prepared from lymph node and treated with Phorbol-12-myristate-13-acetate (PMA)/Ionimycin (Ion) and/or Arc. CD69, CD25, cytokines, proliferation and cell cycle were assayed by flow cytometry. The results showed that, at concentrations of less than 1.00 micromol x L(-1), Arc expressed non-obvious cell damage to cultured lymphocytes, however, it could significantly down-regulate the expression of CD69 and CD25, as well as TNF-alpha, IFN-gamma, IL-2, IL-4, IL-6 and IL-10 on PMA/Ion stimulated lymphocytes. At the same time, Arc could also inhibit the proliferation of PMA/Ion-activated lymphocytes and exhibited lymphocyte G 0/G1 phase cycle arrest. These results suggest that Arc possesses significant anti-inflammatory effects that may be mediated through the regulation of cell activation, cytokines expression and cell proliferation.

OBJECTIVE: To observe the biological behavior of canine bone marrow stromal cells (BMSCs) cultured in vitro with the astragalus polysaccharides-chitosan/polylactic acid (AP-C/PLA) and with the chitosan/polylactic acid (C/PLA) and to find a suitable compound material for periodontal tissue engineering. METHODS: BMSCs (induced 14 days by 50 mg/L vitamine C, 10(-8) mol/L dexamethasone, 10 mmol/L beta-sodium glycerylphosphate) were cultured on AP-C/PLA or C/PLA for 5 days respectively. The BMSCs attachment and the morphology were observed with scanning electronic microscope and the combining rates were counted. Type I collagen synthesis was examined with immunohistochemistry staining and the content of osteocalin was determined with radio-immunological method. RESULTS: Combining rates, type I collagen synthesis, and the content of osteocalin of BMSCs on AP-C/PLA were significantly higher than those on C/PLA. CONCLUSION AP-C/PLA may promote the BMSC proliferation, differentiation and extracellular matrix synthesis, and it can be used as a good scaffold material for bone tissue engineering.

Objective To explore the distribution of water with high level arsenic and prevalence of arsenism along Huai'he River and the surrounding area of Hong'ze lake in Huai'an of Jiangsu. Methods Wate rsamples were collected and tested in 2008 from 18 villages of 6 towns according to history data in 3 counties like Xuyi,Jinhu and Hongze. Samples having arsenic level higher than 0.05 mg/L were investigated by epidemiological method and the patients were diagnosed by Standard of Diagnosis for Endemic Arsenism. Results All 5199 water samples were determined,and 260 water samples were exceeding the national drinking water quality level (0.05 mg/L) in 3 counties,the rates of exceeding diagnosis were 5.6%(247/4454),0.7%(4/597),6.0%(9/148) respectively. Total detected rate of endemic arsenic disease was 5.94%(128/2155). The detected rates of age group of 0 ～ ,20 ～,30 ～ ,40 ～ ,50 ～ ,60 ～ ,70 ～ ,80 ～ were 2.86%(1/35),2.11%(2/95),1.26%(3/239),3.10%(16/516),5.53% (32/579),10.07%(41/407),11.84%(27/228),10.71%(6/56) respectively. The detected rate of male (9.10%,78/857) was higher than that of female(3.85%,50/1298,χ~2 = 25.46,P < 0.01). Conclusions Huai'he River and the surrounding areas of Hong'ze lake like Xuyi,Jinhu and Hongze are identified existing endemic arsenic disease area. The prevention of arsenism should be strengthened in these areas.

OBJECTIVETo observe the effect of Wnt3a-transduced mouse bone marrow mesenchymal stem cells (MSC) on the proliferation of T lymphocytes.

METHODSMSC were isolated from C57BL/6 mouse bone marrow and expanded in vitro, then identified by flow cytometry and their differentiation capacity into osteocytes and adipocytes were determined. Recombinant plasmids containing Wnt3a gene, were transfected with lipofectamine into HEK293 cells by the AdEasy system. Viral particles were collected to infect MSC and adenovirus vector expressing GFP (Ad-GFP) was used as control. The expression of GFP in MSC was observed using fluorescence microscopy and the protein levels of Wnt3a and β-catenin were determined by Western blot. Wnt3a-transduced and Ad-GFP transduced MSC were separately cocultured with spleen lymphocytes stimulated by ConA, at the ratio of 1:100, 1:50 or 1:10 respectively. The proliferation rate of T lymphocytes was estimated by Cell Cout Kit-8 (CCK-8) and the level of cytokine by ELISA.

RESULTSFCM analysis showed that the MSC were highly positive for CD90.2, CD44 and negative for CD34, CD45, they could differentiate into osteoblasts and adipocytes after induction; The titer of recombinant adenoviruses was up to 1 × 10(10) pfu/ml. After infected with the adenoviruses, MSC had the strongest GFP expression at 72 h and the efficiency of infection was 50%-60%. The expressions of Wnt3a and β-catenin protein in the Wnt3a-transduced MSC were significantly increased. MSC could suppress the proliferation of T lymphocytes in a dose-dependent manner. When MSC cocultured with spleen lymphocytes at 1:10 ratio, T lymphocyte proliferation rate and the level of IFN-γ were (55.41 ± 1.75)% and (326.70 ± 14.41) pg/ml respectively in Ad-GFP transduced MSC group, while in Wnt3a-transduced MSC group, they were (37.27 ± 2.66)% and (218.80 ± 12.93) pg/ml respectively. There was no effect on the production of IL-2.

CONCLUSIONCompared to Ad-GFP transduced MSC, Wnt3a-transduced MSC exhibit a more potent inhibitory effect on the proliferation of T lymphocytes.

OBJECTIVETo study the effect of delayed sequential bone marrow transplantation on acute graft-versus-host disease (aGVHD) in major H-2 incompatible mouse transplantation.

METHODSC57BL/6 (H-2b) mice were used as donors and BALB/c (H-2d) mice as recipients. BALB/c mice were given 8.0 Gys total body irradiation (TBI) on day 0 and infused with a blend of bone marrow cells and spleen cells in different time. Transplantation was carried out as follows: group I TBI on day 0 and transplantation at 4 h after TBI; groups of II TBI on day 0 and transplantation at 4 h, d1, d2, d3 after TBI; groups III TBI on day 0 and transplantation at day 4 after TBI; groups IV TBI on day 0 and transplantation at day 4 through day 7 after TBI. Recipient's spleen H-2b cells were detected by flow cytometry and the level of serum cytokines (IL-2, IL4, IL-6, IL-10 and IFN-gamma) by ELISA. The survival, aGVHD and hematopoietic recovery were observed.

RESULTSaGVHD occurred in group I and the mice all died within 3 weeks after transplantation. The 60 day survival rates of groups of II and III were 30% and 50% respectively. The degree of aGVHD in group III was modest and the survival rate was higher than that in other groups (P <0.05). The peak time of IL-2, IFN-gamma, IL-4 and IL-10 in groups III and IV were later than that in group I. The levels of IL-4 and IL-10 in groups III and IV were higher than that in group I and for the levels of IL-2 and IFN-gamma were on the contrary (P < 0.05). The level of IL-6 in all groups peaked on day 5 to day 10 after TBI and was higher in group I than in others (P <0.05). In group IV the mean value of donor H-2b cells was (98.1 +/- 1.1)% on day 60 and WBC counts recovered normal on day 20.

CONCLUSIONSDelayed sequential transplantation can reduce the morbidity of aGVHD ,improve the survival rate and not affect the engraftment and reconstitution of hematopoiesis in mouse allo-BMT. The mechanism of aGVHD prevention may be related to the reducing of type 1 cytokines of T lymphocyte and the increasing of type 2 cytokines.

OBJECTIVETo explore the effect of hyperthermic intraoperative intraperitoneal chemotherapy (HIIC) on the postoperative metastatic rate and survival rate of advanced gastric cancer (AGC).

METHODSIn HIIC group, patients received HIIC (mitomycin C 30 mg and cisplatin 100 mg were added into 2000 ml distilled water, heated to 42 approximately 45 degrees C, perfused to abdominal cavity for 30 min and then sucked) and intravenous chemotherapy after operation (5- FU 10 approximately 15 mg/kg, mitomycin C 0.1 approximately 0.15 mg/kg, adriamycin 0.5 approximately 1 mg/kg i.v drip, once a week for 2 approximately 3 weeks). In control group, patients received intravenous chemotherapy only. The postoperative metastatic rate and survival rate (1- , 3- and 5- year) of patients were compared between 92 cases of AGC undergone HIIC and 120 cases of AGC without HIIC (control group).

RESULTSThe peritoneal recurrence rates after operations occurred within two years were 14.1% and 37.5% in HIIC group and control group respectively (P < 0.01). The 1- , 3- , and 5- year survival rates in HIIC group were 98.9%, 68.5%, and 52.2% and in control group 95.0%, 56.7% and 37.5% respectively. The 3- , and 5- year survival rates were significantly different between the two the groups (P < 0.05).

CONCLUSIONHIIC can kill isolated intraperitoneal cancer cells, reduce peritoneal recurrence rate after operations, raise significantly survival rate of patient, and improve the prognosis of AGC.

This study was purposed to explore whether the blood transfusion of surgical patients can increase the severity of postoperative infection by a retrospective analysis of patients with postoperative infection in Chinese PLA General Hospital. By using a software "clinical transfusion database" developed by our department, 150 infected surgical cases were retrieved and divided into deep infection group and superficial infection group according to the infected location. These two groups were compared in term of the patient's age, duration of hospitalization, red blood cell transfusion volume, none-red cell transfusion volume, transfusion frequency and average transfusion volume. The results showed that red blood cell transfusion volume or none-red cells transfusion volume of patients with superficial infection was 4.50 (0 - 59) U or 2.95 (0 - 119.6) U, and that of deep infection was 9.00 (0 - 153) U and 8.05 (0 - 136.6) U, the differences was significant (P < 0.05). Between two groups, the transfusion frequency showed the most significant difference, median in the patients with superficial infection was about 2 (1 - 31) times, less than the deep infection group about 4 (1 - 49) times (P < 0.001). There was no significant difference between two groups in the average transfusion volume. It is concluded that perioperative blood transfusion volume and frequency of surgical patients seems to display a positive correlation with the degree of postoperative infection.
