The score on gastrointestinal dysfunction in the treated group was significantly higher than that of the control group (P<0.05). Conclusions Xingqi Tongfu Pad can promote the recovery of gastrointestinal function after abdominal operation. It deserves popularization for its positive effect, cheap price and easy operation.

Objective To explore the predictive value of the expression of serum forkhead box protein M1(FOXM1)and insulin-like growth factor 2(IGF2)on the prognosis of elderly patients with heart failure complicated with pneumonia.Methods A total of 126 elderly patients with heart failure complicated with pneumonia admitted to Handan Central Hospital from March 2021 to June 2022 were included in case group.According to the follow-up results,the 122 patients were grouped into poor prognosis group(n=33)and good prognosis group(n=89).Meanwhile,126 healthy people in the same period were included as the control group.The levels of serum FOXM1 and IGF2,forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1)in the two groups(case group and control group)were measured.Spearman method was used to analyze the correlation between serum levels of FOXM1 and IGF2 and heart function classification in elderly patients with heart failure complicated with pneumonia.The predictive value of serum FOXM1 and IGF2 levels in elderly patients with heart failure complicated with pneumonia was analyzed by receiver operating characteristic(ROC)curve.Results Compared with the control group,the levels of FOXM1(2.39±0.55 vs 1.06±0.21)and IGF2(71.33±7.96pg/ml vs 47.82±5.14pg/ml)in the case group were significantly higher(t=25.358,27.581,all P<0.05).Compared with the good prognosis group,the levels of serum FOXM1(3.87±1.06 vs 1.95±0.51)and IGF2(85.88±9.54pg/ml vs 69.14±8.73pg/ml)in the poor prognosis group were significantly higher,and the differences were statistically significant(t=13.453,9.174,all P<0.05).There were significant differences in heart function classification between the good prognosis group and the poor prognosis group,and the differences were statistically significant(χ2=7.120,P<0.05).Compared with the poor prognosis group,FEV1(1.24±0.32 L vs 1.08±0.25 L)and FEV1/FVC(55.46%±5.77%vs 52.30%±5.38%)in good prognosis group were significantly higher,and the differences were statistically significant(t=2.592,2.735,all P<0.05).The levels of serum FOXM1 and IGF2(r=0.496,0.517,all P<0.05)in elderly patients with heart failure complicated with pneumonia were positively correlated with heart function classification.ROC curve results showed that the area under the curve(AUC)of serum FOXM1 alone in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was 0.854(95CI%:0.779～0.912),with sensitivity and specificity of 75.76%and 86.52%,respectively,and the optimal cut-off value of 2.75.The AUC of IGF2 alone in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was 0.874(95CI%:0.802～0.927),with sensitivity and specificity of 72.73%and 85.39%,respectively,and the optimal cut-off value of 78.30 pg/ml.The AUC of the combination of the two in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was greater than the AUC diagnosed by serum FOXM1 alone and IGF2 alone(Z=2.737,2.413,P=0.006,0.016).Conclusion The serum levels of FOXM1 and IGF2 were increased in elderly patients with heart failure complicated with pneumonia,indicating the combined detection of the two may have a high predictive value for the prognosis of patients.

Objective To study the effect of adenosine preconditioning on cell apoptosis and expressions of glucose-regulated protein (GRP-78) and cysteinylaspartate-specific protease 12 (caspase-12) in rats with spinal cord ischemia-reperfusion injury. Methods Twenty-seven rats were randomized into 3 equal groups and subjected to sham operation (group A), spinal cord ischemia-reperfusion injury (group B), or ischemia-reperfusion injury with adenosine treatment. Spinal cord ischemia-reperfusion injury was induced by cross-clamping of the abdominal aorta inferior to the left renal artery. The spinal cord function was assessed using the Modified Tarlov Scale at 6, 12, and 24 h after reperfusion. At 24 h after reperfusion, histological analysis was carried out with HE staining; cell apoptosis and viability were determined with TUNEL staining, and the expressions of GRP-78 and caspase-12 proteins were determined with Western blotting. Results HE staining of the spinal cord showed extensive spinal cord injury such as cell edema in group B as compared with group C. Compared with group A, group B showed a significantly increased number of apoptotic cells;the number of apoptotic cells in group B was greater than that in group C. Compared with group B, group C showed significantly increased GRP-78 expression (P<0.01) and decreased caspase-12 expression (P<0.01). Conclusion Adenosine can up-regulate GRP-78 expression and down-regulate caspase-12 expression, and protects the spinal cord against ischemia-reperfusion injury by inhibiting cell apoptosis.

OBJECTIVE： To study the effects of ivermectin on the migration and invasion of human gastric cancer cell lines BGC-823 and MGC-803 and its mechanism. METHODS： After treated with 0， 2.5， 5， 10， 20， 40 μmol/L ivermectin for 24 h， inhibitory rate of human gastric cancer cell lines BGC-823 and MGC-803 were detected by MTT assay. Effects of 5 μmol/L ivermectin and phosphate buffercontaining 0.67‰ dimethyl sulfoxide （control group） for 24 h on the migration and invasion of` gastric cancer cells BGC-823 and MGC-803 were observed by Transwell chamber invasion assay.Western blot assay was used to detect the protein expression of TGF-β1， TGF-βR， Smad2 and Smad3 in epithelial-mesenchymal transition （EMT） markers E-cadherin， N-cadherin， Vimentin， Snail and EMT transduction pathway TGF-β/smad of BGC-823 and MGC-803 cells after treated with 5， 10 μmol/L ivermectin and phosphate buffercontaining 0.67‰ dimethyl sulfoxide （control group） for 24 h. RESULTS： Ivermectin could inhibit the growth of BGC-823 and MGC-803， inhibitory rate of it was positively correlated with its concentration. Compared with control group， the number of migration and invasion BGC-823 and MGC-803 cells were decreased significantly after treated with 5 μmol/L ivermectin （P＜0.01 or P＜0.001）； the expression of E-cadherin protein was enhanced significantly in BGC-823 and MGC-803 cells after treated with 5 and 10 μmol/L ivermectin （P＜0.05 or P＜0.01 or P＜0.001）； the protein expression of N-cadherin， Vimentin， Snail， TGF-βR， Smad2 and Smad3 were decreased significantly （P＜0.05， P＜0.01 or P＜0.001）； protein expression of TGF-β1 was decreased significantly after treated with 10 μmol/L ivermectin （P＜0.05）. CONCLUSIONS： Ivermectin can significantly inhibit the migration and invasion of gastric cancer cells BGC-823 and MGC-803， and inhibiting the biological activity of EMT by reducing the expression of TGF-β/smad pathway is one of the mechanisms that inhibit the migration and invasion of gastric cancer cells.
