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.

OBJECTIVETo investigate the optimal time and method of the early repair of the full layer eyelid defect caused by chemical burn.

METHODSFree nasal septum mucosal cartilage flap with muscle flap, skin grafting, or skin flap were performed in 18 cases (19 eyelids) with chemical burn within 4 postburn weeks. Eyelid reconstruction and corneal transplantation were performed at the same time in 4 patients.

RESULTSAll the reconstructed eyelids and transplanted cornea survived. The incidence of severe complications, such as exposure keratitis, corneal ulcer and eyeball perforation decreased.

CONCLUSIONFull layer eyelid defect caused by chemical burn should receive early reconstruction and repair, including timely reconstruction of eyelid for the sake of protecting the eyesight and of alleviating the inflammatory reactions, and the corneal transplantation should be done at the same time to avoid corneal perforation. Nasal septum mucosal cartilage flap could be ideal for the eyelid reconstruction.

OBJECTIVETo investigate the role of p38 mitogen-activated protein kinase (MAPK) signal transduction pathway in the Kupffer cells production of tumor necrosis factor (TNF)-alpha and interleukin (IL)-1beta in severely burns rats.

METHODSMale health adult Sprague-Dawley rats were randomized into four groups: sham burn rats given vehicle, sham burn rats given the p38 MAP kinase inhibitor SB203580, rats given a 30% total body surface area (TBSA) full-thickness burn and fluid resuscitation plus vehicle, and burn rats given injury and fluid resuscitation plus SB203580. Rats from each group were killed at 24 h after burn or sham burn and Kupffer cells (KCs) were isolated. After 18 h incubation, KCs next were stimulated with 50 ng/ml of LPS for 18 h. After stimulation, supernatants were removed for analysis of TNF-alpha and IL-1beta levels by ELISA. The TNF-alpha and IL-1beta mRNA expressions (by quantitative real-time RT-PCR) and the activities of p38 MAPK and JNK (by Western blot analysis) in KCs were examined.

RESULTSEighteen hours after 50 ng/ml LPS stimulation, KCs from burn rats released significantly higher levels of TNF-alpha and IL-1beta than did shams. The mRNA levels of TNF-alpha and IL-1beta in KCs increased significantly postburn. Western blot analysis suggested that expression of phosphorylated p38 MAPK and JNK were increased in KCs harvested from burn group after stimulation with LPS compared with those from sham group. In vivo administration of SB203580 markedly suppressed both the release of TNF-alpha and IL-1beta and the mRNA expressions of TNF-alpha and IL-1beta in KCs from both sham and burn rats. p38 MAPK activity in KCs was abolished by administration with SB203580, whereas JNK was not.

CONCLUSIONSp38 MAPK signal transduction pathway mediates KCs production of proinflammatory cytokines TNF-alpha and IL-1beta in severely burned rats.

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.

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.
