2004年5月至2006年3月,南阳市中心医院肿瘤科分别采用利血生加升血小板胶囊、国产重组人白细胞介素-11(rhIL-11)治疗恶性肿瘤放化疗后血小板减少症患者52例,并比较2者的疗效,现报道如下.
AIM: To observe the alterations of all kinds of pathophysiological and biochemical markers in rat model with endotoxin-induced acute lung injury (ALI) after pentoxifylline (PTX)treatment so as to approach the intervention effect of PTX treatment on ALI. METHODS: The rat model of ALI was made by injecting lipopolysacharide (LPS) at a dose of 4 mg/kg into vena caudalis. Seventy-two male SD rats with matched month age and weight were randomly divided into 3 groups: control group (NS), experimental group (LPS) and PTX treatment group, 24 rats each group. In control group physiologic saline was injected into vena caudalis; in experimental group 4 mg/kg LPS was injected into vena caudalis; in treatment group 0.036 mol/L PTX (10 mg/kg) was intraperitoneally (ip) injected 1 h before LPS injection into vena caudalis. Instantly after ALI rat modes were established successfully in erperimental group, 10 mg/kg PTX was injected ip, totally for 5 times, at an interval of 1 h; in the other 2 groups, same-volume physiologic saline was given in the same way. We determined PaO2, pH, PaCO2, lung coefficient, lung water content, lung permeability index, and detected the percentages of neutrocyte and macrophage in bronchoalveolar lavage fluid, the levels of malondialdehyde(MDA), superoxide dismutase(SOD), nitric oxide(NO) and inducible nitric oxide synthase(iNOS), and observed the pathomorphology of lung tissue. RESULTS: In treatment group compared with experimental group, PaO2 and pH stepped up, PaCO2 stepped down, lung coefficient (0.59±0.17 vs 0.92±0.11, P<0.05), lung water content(84.46±0.39 vs 80.22±0.37, P<0.05), lung permeability index(7.28±0.54 vs 12.32±0.28, P<0.05) were all decreased significantly, the percentage of neutrocyte in bronchoalveolar lavage fluid was reduced, NO and iNOS were depressed significantly, and SOD was improved significantly(P<0.05). The lesion of lung tissue in treatment group was lighter than that in experiment group through pathological observation. CONCLUSION: PTX can improve energy metabolism and reduce the cytotoxicity in LPS-induced ALI rats. PTX plays a role in intervening and preventing the development of ALI.

Objective In order to contrast the therapeutic outcome of omeprazole and mosapride treating reflux esophagitis and to summarize and evaluate the curative effects and applicable scope of the two,24-hours esophageal pH monitoring combined with clinical symptom and endoscopic observation was used.Methods 72 patients with reflux esophagitis identified and dignosed by endoscopic were collected in Hospital of Anyang Iron Steel Group from Jan.2002 to Dec.2005.The patients were divided into three groups randomly: associated-dose group(24 cases)/ omeprazole group(24 cases)/ mosapride group(24 cases),observing their corresponding therapuatic effects.Associated-dose group: treated with omeprazole 20mg qd every morning,and mosapride 5mg tid,30 minutes before every meal;omeprazole group: treated with omeprazole 20mg qd every morning;mosapride group: treated with mosapride 5mg tid,30 minutes before every meal.The period of treatment was 4 weeks,observed markers such as pyrosis,spontaneous esophageal chest pain,regurgitation,acid reflux,belching clinical symptom,dysphagia,the detect data for the pH of esophagus in 24-hours esophageal pH monitoring,and countercheck endoscopic results for 4 weeks after treatment were taken as criteria for comparison.Results The symptom control rates in associated-dose group,omeprazole group and mosapride group for 2 weeks after treatment were 83.33%,70.83% and 54.17%,respectively(P0.05);for 4 weeks after treatment were 95.83%,91.67% and 79.17%,respectively(P0.05);the endoscopic efficiency was 95.83%,83.33% and 62.50%,respectively(P0.05);the data for pH detect in esophagus were improved.Those in omeprazole group were similar with that in mosapride group.However,for the group with grade Ⅱ~Ⅳ esophagitis,the endoscopic effects and the improvement for pH detect in omeprazole group were better than those in mosapride group,but the therapeutic effects in omeprazole group and mosapride group were not as good as those in associated-dose group.Conclusion Omeprazole and mosapride have good theraputic efftcts for reflux esophagitis.For the reflux esophagitis above grade Ⅱ,treating patients with only omeprazole is better than mosapride,but both of their therapeutic effiency are not as good as those treated by combining omeprazole with mosapride.Above all,the research shows that it is very reasonable and meaningful to treat reflux esophagitis corresponding their grades.

Objective To observe the effects of pentoxifylline(PTX) on newborn rats with hypoxic-ischemic encephalopathy(HIE). Methods Models of 7-day-old newborn Wistar rats with HIE were established and 72 rats were randomly divided into sham operation group,HIE model group and PTX group.72h after hypoxic-ischemic operation the left side brains were taken out and the water content,intracellular calcium content(%) and the level of SOD,MDA,NOS,NO were measured. Results Compared with HIE model group,the content of water and calcium and the level of MDA,NOS,NO were markedly reduced(P0.05,0.01,0.05,0.05,0.05),while the levels of SOD were increased significantly(P0.05). Conclusion PTX could protect brain of neonatal rat against hypoxic-ischemic damage,which might be the result of the improvement of energy metabolism and the removal of local cytotoxic substance.
