OBJECTIVETo observe clinical therapeutic effects of acupuncture for pattern of liver-stagnation and spleen-deficiency in diarrhea-predominant irritable bowel syndrome (D-IBS) and its impact on cell factors.

METHODSForty cases were selected and divided into an acupuncture group (21 cases) in which acupuncture was applied and a medicine group (19 cases) in which oral administration of dicetel and bifidobacterium lactobacillus triple viable capsules were applied. The symptom scores, level of Th1-type cytokine (IFN-gamma, IL-2) and Th2-type cytokine (IL-4, IL-10) and ratio of IFN-gamma to IL-4 were compared in two groups before and after treatment to analyze acupuncture effect.

RESULTSThe clinical symptoms were improved after one-week treatment in the acupuncture group (P<0.05), which had faster onset than the medicine group (P<0.05). The total effective rate was 90.48% (19/21) in the acupuncture group, which was superior to 78.95% (15/19) in the medicine group (P<0.05). Compared with medicine treatment, imbalanced condition of Th1/Th2 was turning towards the direction of Th2 after acupuncture, indicating a tendency to recover the balance.

CONCLUSIONThe clinical efficacy of acupuncture for D-IBS has close relationship with effectively improving balance of Th1/Th2 in patients with liver-stagnation and spleen-deficiency.

Background Since the measurement method establishment of serum ferritin abroad in early period of theseventies, the iron deficiency had been divided into two types: the non-anemia and anemia types. In orderto go step further studies, we must ertablish the bemoglobin targets of the two types. Methods One hurdred and fifty-two children in experimontal group, from 6 to 7 years old, and allcome from Qinghai province. There are 29 children in Xining city, 24 in Guide, 26 in Gongbe, 40 in Gui-nan and 33 in Maduo countics. There are 36 health children aged from 6 to 7 years old in the controlgroup, and all comes from Beijing. The Hb, RBC, HCT, HCTW and FEP wcre determined. Results The three targets correlating with Hb (Hb, MCH and MCHC); correlating with RBC (RBC,HCT and MCV); the two targets correlating with RBC_weight (HCTW and CMCW) and correlating withFEP of RBC(FEP and MCEP) have very significant difference between experimental group and control group. Conclusion The determination values of the 10 targets are not same in children in different districts,and the values of all the target: are increased on different degree along with the increase in altitude of ele-vation. There is very important significance on the studies of iron deficiency and altitude hypoxia to establish the normal values of the 10 targets.

OBJECTIVETo explore the expression of connective tissue growth factor (CTGF) in pancreatic cancer and its influence on the proliferation and migration of cancer cells.

METHODSThe expression of CTGF in pancreatic cell line PANC-1 cells was analyzed by real-time PCR and in pancreatic carcinoma (50 cases) tissues by immunohistochemistry. The ability of proliferation and migration in vitro of PANC-1 cells was tested by MTT assay, scratch test and Boyden chamber test after the CTGF gene was overexpressed by Ad5-CTGF or silenced with Ad5-siCTGF transfection.

RESULTSCTGF was overexpressed in both pancreatic cancer cells and tissues. Overxpression of CTGF leads to increased proliferation and migration of PANC-1 cells. The CTGF-transfected PANC-1 cells showed apparent stronger proliferation ability and scratch-repair ability than that of empty vector controls. The results of Boyden chamber test showed that there were 34 cells/field (200× magnificantion) of the CTGF-transfected overexpressing cells, much more than the 11 cells/field of the empty vector control cells; and 6 cells/microscopic field of the Ad5-siCTGF-transfected silenced cells, much less than the 15 cells/field of the control cells.

CONCLUSIONSCTGF is overexpressed in both pancreatic cancer cells in vitro and in vivo, indicating that it may play an important role in the cell proliferation and migration in pancreatic cancer.

OBJECTIVETo investigate the role of p38 mitogen-activated protein kinase (MAPK) signal transduction pathway in the acute lung injury of severely burned rats.

METHODSForty-eight adult healthy rats were randomly divided into three groups: sham group, burn control group, and burn + SB203580 group. A third-degree burns over 30% total body surface area rat model was used and pulmonary capillary permeability, lung water content, pulmonary histology and p38 MAPK activity were measured at 24 hours postburn.

RESULTSBurn trauma resulted in increased pulmonary capillary leakage permeability (42.5 +/- 4.7 vs. 12.1 +/- 1.4, P < 0.01), elevated lung water content (P < 0.05), and worsen histologic condition. There was a significant activation of p38 MAPK at 24 hours postburn compared with control. SB203580 inhibited the activation of p38 MAPK, reduced the pulmonary capillary leakage permeability (24.7 +/- 2.9 vs. 42.5 +/- 4.7, P < 0.01), decreased lung water content, and prevented burn-mediated lung injury.

CONCLUSIONThe activation of p38 MAPK is one important aspect of the signaling event that contributes to burn-induced lung injury.

OBJECTIVETo investigate the interaction between p38 mitogen-activated protein kinase signal transduction pathway and nuclear factor (NF)-kappaB/IkappaB system on the proinflammatory cytokines release after burn trauma.

METHODSHuman monocyte line THP-1 were incubated with serum from eight healthy controls, burn sera, burn sera pretreatment with SB203580, and burn sera pretreatment with pyrrolidine dithiocarbamate (PDTC). After 24 hours incubation with serum, tumor necrosis factor (TNF)-alpha and interleukin-1beta (IL-1beta) levels in THP-1 culture supernatants were measured by ELISA. The activities of p38 MAPK and expressions of IkappaBalpha in THP-1 were measured by Western blot analysis. The EMSA method was used to characterize the binding activities of NF-kappaB and activating protein (AP)-1 in THP-1.

RESULTSIn comparison with normal controls, burn sera resulted in a significant higher level release of TNF-alpha and IL-1beta in THP-1 [(7.30 +/- 0.84) ng/ml vs (2.20 +/- 0.28) ng/ml, P < 0.05; (2.88 +/- 0.38) ng/ml vs (0.81 +/- 0.14) ng/ml, P < 0.05], which were significantly inhibited by pretreatment with SB203580 or PDTC. Burn sera showed increased activities of p38 MAPK and AP-1 in THP-1 (4728 +/- 582 vs 1291 +/- 163, P < 0.05; 946 +/- 137 vs 361 +/- 40, P < 0.05), which were abolished by pretreatment with SB203580 but not PDTC. The expression of IkappaBalpha in THP-1 incubated with burn sera was significantly decreased than those incubated with control sera (1211 +/- 115 vs 2658 +/- 318, P < 0.05), which were abolished by pretreatment with PDTC but not SB203580. Burn sera also leaded to an increased activity of NF-kappaB in THP-1 (1636 +/- 170 vs 317 +/- 32, P < 0.05), which were abolished by pretreatment with PDTC but not SB203580.

CONCLUSIONSThere are no direct interaction between p38 MAPK signal transduction pathway and NF-kappaB/IkappaB pathway. These two pathways, which regulate the production of TNF-alpha and IL-1beta in monocyte following burn trauma, are parallel and independent.
