OBJECTIVETo study the role of nuclear factor (NF)-kappaB pathway with p38MAPK in Curcuma wenyujin diterpenoid compound C (CDCC) fighting against inflammation and inducing gastric cancer cell apoptosis by stimulating gastric cell SGC7901 with tumor necrosis factor-alpha (TNF-alpha).

METHODSHuman umbilical vein endothelial cells (HUVECs) and human gastric cancer SGC-7901 cells were in vitro acted by CDCC in different concentrations at different time points. Their growth inhibition ratios were measured by MTT assay. The apoptosis rate of gastric cancer cells was detected by Annexin V-FITC/PI double staining. Nuclear translocation of p65 was detected by cell immunofluorescence. Expression levels of p38MAPK/P-p38MAPK, p65/P-p65, and Caspase 3/P-Caspase 3 were measured by Western blot.

RESULTSCDCC had significant inhibitory effect on the proliferation of SGC-7901. It also could effectively induce the apoptosis of gastric cancer cell SGC-7901. It also could reduce nuclear translocation of p65 in gastric cancer cell SGC-7901. Results of Western blot indicated that expression levels of p38MAPK and p65 were reduced and the expression level of Caspase-3 was elevated along with increased concentrations of CDCC (P<0.05).

CONCLUSIONApoptosis executive protein Caspase 3 activated by regulating p65 via p38MAPK might be one of possible mechanisms for CDCC fighting against inflammation and gastric cancer.

Objective To evaluate the endovascular treatment of diffuse aortoiliac occlusive diseases. Methods Thirty-two patients underwent endovascular treatment in which rest pain was found in 84.38%, foot local gangrene in 15.62%. Mean age was 69.7 years (range, 52 years to 81 years) and 71.9% was male. Trans Atlantic Inter-Society Consensus C and D disease was respectively in 40.6% and 59.4% patients. Mean length of vasculopathy was (14.6 ± 1.2) cm (range, 4.5 cm to 19.5 cm) All patients had prohibitive risk for open revascularization. With the approach from femoral artery or brachial artery, combined techniques, such as recanahzation, balloon dilation, stent placement and concomitant common femoral endarterectomy were used. Results Technical success was achieved in twenty-nine patients(90.63%). The complication rate was 3.45%. Clinical status was markedly improved in eight cases (27.59%) and moderately improved in twenty-one cases(72.41%). Mean postoperative ABI was 0.73 ± 0.12, mean preoperative ABI was 0.32 ± 0.09. Significant differences were seen between postoperative ABI and preoperative ABI(P<0.05). Mean time of follow-up was (13.9±6.2) months. At 6 months, primary patency was 81.82% and secondary patency was 89.09%. At 12 months, primary patency was 63.64% and secondary patency was 80.18%. Conclusion Combined multiple endovascular technique is a safe and effective method in the treatment of poor risk diffuse aortoiliac occlusive diseases.

OBJECTIVETo study the absorption kinetics of dehydrocavidine in rats' stomachs and intestines.

METHODThe absorption kinetics was investigated by the in situ perfusion in rats and the concentrations of drug perfusion solutions were determined by HPLC.

RESULTThe hourly absorption percentages of dehydrocavidine in stomach, small intestine were 8.88%, 2.08%, respectively. Although the absorption rate constants of dehydrocavidine in duodenum and jejunum are more than that in ileum and colon, there is no significance difference between them. The absorption rate constants kept at the same level when the concentrations of drug perfusion solution are at middle and high level. The increase of the pH of perfusion solution didnt significantly affect the absorption rate constants of the drug.

CONCLUSIONDehydrocavidine was absorbed poorly at stomach and all segments of intestine in rats, but the absorptions in stomach are better than intestine. Dehydrocavidine was absorbed mainly via passive transport mechanism between middle and high concentration levels.

OBJECTIVETo investigate the placement of a long tube into the small intestine under fluoroscopic guidance and to evaluate its decompression effect on early postoperative small bowel obstruction (EPSBO).

METHODSFifty-four patients with EPSBO requiring decompression between April 2010 and July 2014 were enrolled in the study. Insertion of a long tube was guided by fluoroscopy. We first used the guide wire to pass the pylorus and then used the 10 Fr feeding tube as an exchangeable tube to put the superstiff wire into the duodenum. Finally the long tube could be passed over the guide wire through the pylorus into the intestine. The total procedure time, the radiation exposure time, and the incidence of complications were evaluated.

RESULTSThe long tubes passed into the jejunum on initial insertion for all patients, so the success rate of this technique was 100%. The long tube was inserted into ileum in 18 patients. The mean total procedure time was 34.4 ± 8.6 minutes, and the mean radiation exposure time 18.9 ± 6.8 minutes. A total of 47 patients (87%) experienced full recovery following long-tube decompression and without the need for surgical intervention.

CONCLUSIONSUsing the wire-exchange technique, it is easy to place a long tube into the small bowel under fluoroscopic guidance. This decompression method is safe and effective for management of EPSBO.

OBJECTIVETo investigate the effects of serotonin (5-HTIA) receptors in the hippocampal dentate gyrus (DG) on active avoidance learning in rats.

METHODSTotally 36 SD rats were randomly divided into control group, antagonist group and agonist group(n = 12). Active avoidance learning ability of rats was assessed by the shuttle box. The extracellular concentrations of 5-HT in the DG during active avoidance conditioned reflex were measured by microdialysis and high performance liquid chromatography (HPLC) techniques. Then the antagonist (WAY-100635) or agonist (8-OH-DPAT) of the 5-HT1A receptors were microinjected into the DG region, and the active avoidance learning was measured.

RESULTS(1) During the active avoidance learning, the concentration of 5-HT in the hippocampal DG was significantly increased in the extinction but not establishment in the conditioned reflex, which reached 164.90% ± 26.07% (P <0.05) of basal level. (2) The microinjection of WAY-100635 (an antagonist of 5-HT1A receptor) into the DG did not significantly affect the active avoidance learning. (3) The microinjection of 8-OH-DPAT(an agonist of 5-HT1A receptor) into the DG significantly facilitated the establishment process and inhibited the extinction process during active avoidance conditioned reflex.

CONCLUSIONThe data suggest that activation of 5-HT1A receptors in hipocampal DG may facilitate active avoidance learning and memory in rats.

OBJECTIVETo explore effects and action mechanism of warm moxibustion on regulation of blood lipids and anti-atherosclerosis.

METHODSForty-one male Japanese big-ear white rabbits were randomly divided into a blank group (10 rabbits), a model group (10 rabbits), a moxibustion group (10 rabbits) and a medication group (11 rabbits). Normal diet was applied in the blank group while high-cholesterol diet combined with injection of bovine serum albumin were applied in the rest groups to establish rabbit model of atherosclerosis. After establishment, the model group was not intervened and warm moxibustion was applied in the moxibustion group at "Zusan-li" (ST 36) and "Shenque" (CV 8), 10 min per acupoint per day for continuous 4 weeks. The medication group was treated with intragastric administration of lovastatin capsule (3.6 mg/kg) for continuous 4 weeks. The level of blood lipids, such as total cholesterol (TC), triglyceride (TG), and content of CD40 ligand (CD40L), soluble CD40 ligand (sCD40L) and expression of nuclear factor NF-kappaB were tested after 4 weeks.

RESULTSCompared with the model group, the moxibustion group and medication group could effectively reduce the contents of TC and low density lipoprotein (all P < 0.05), lower the level of sCD40L [(8.310 +/- 1.221) ng/mL in the model group, (7.097 +/- 0.846) ng/mL in the moxibustion group and (7.354 +/- 0.631) ng/mL in the medication group], reduce expression of CD40L [(0.235 +/- 0.179) mm2 in the model group, (0.072 +/- 0.079) mm2 in the moxibustion group and (0.039 +/- 0.015) mm2 in the medication group] and NF-kappaB [(0.145 +/- 0.052)mm2 in the model group, (0.052 +/- 0.012) mm2 in the moxibustion group and (0.036 +/- 0.013) mm2 in the medication group], indicating the significant difference (P < 0.05, P < 0.001). There was no statistical difference between the moxibustion group and medication group (all P > 0.05).

CONCLUSIONThe warm moxibustion has great effect on regulation of blood lipids and anti-atherosclerosis, in which lowering expression of CD40-CD40L could be one of possible mechanisms to take effect of anti-atherosclerosis.

OBJECTIVETo observe the effect of Salvia miltiorrhiza Injection (SMI) and Shengmai Injection (SI) on liver function and fibrosis related indexes in patients with chronic hepatitis B.

METHODSSeventy-nine chronic hepatitis B patients were randomly divided into the SMI group (n=47) and the SI group (n=32), they were treated with SMI and SI respectively on the basis of conventional treatment. The therapeutic course was 35 days for both groups. The changes of main symptoms and physical signs were observed, and indexes of liver function and fibrosis including serum hyaluronidase, laminin, III type precollagen (PC-III) and IV type collagen (IV-C) were investigated before and after treatment.

RESULTSSymptoms, physical signs and liver functions were improved obviously in both SMI and SI groups, SI showed better effect than SMI (P < 0.05). The four liver fibrosis indexes declined significantly in the SMI group after treatment (P < 0.05), but no obvious change of those was found in the SI group (P > 0.05), showing significant difference between the two groups (P < 0.05). Conclusion SMI is effective in improving liver function and inhibiting liver fibrosis, and SI has even better effect in improving liver function than SMI, though it shows no anti-liver fibrosis effect.
