Objective To investigate the protective effects of G CSF on lungs of rats with acute cholangitis and changes in blood TNF and TXA 2/PGI 2 by treating the rats with G CSF. Methods Seventy two Wistar rats were randomized into the control, infected and treated groups. We established the model of cholangitis in the rats with injection of E. coli 25922 into the bile duct. The animals in the treated group were pretreated with G CSF 500 ng/day bid) for 5 days before the E. coli injection. The levels of blood TNF and TXA 2/PGI 2 were measured at the 3rd, 6th and 12th h after the injection. Meanwhile, the morphological changes in lungs of the rats were observed. Results The morphological changes in lungs were milder and levels of blood TNF and TXA 2/PGI 2 were significantly lower in the treated group than in the infected one (P

Objective To observe the effect of conventional therapy plus trimetazidine on alcoholic cardiomyopathy (ACM) and plasma brain natriuretic peptide (BNP).Methods Eighty-six cases of ACM patients were divided into control group and observation group by random digits table method with 43 cases each.Control group was treated with conventional therapy,while observation group was added trimetazidine.Course of treatment was 3 months.The left ventricular ejection fraction (LVEF),left ventricular end diastolic diameter (LVEDD),6 min walk distance,plasma BNP before and after treatment and the efficiency in two groups was observed and compared.Results LVEF,LVEDD,6 min walk distance,BNP before treatment in control group were respectively (37.2 ±7.4)％,(57.6 ±7.4) mm,(312.8 ±21.6) m,(846.2 ±63.7)μg/L,and the indicators in observation group were respectively (38.5 ±8.1)％,(57.1 ±6.8) mm,(316.5 ± 23.9) m,(857.6 ± 61.4) μ g/L.All indicators between two groups was no statistically different (P＞0.05).LVEF,LVEDD,6 min walk distance,BNP after treatment in control group were respectively (43.5 ±8.6)％,(54.3 ± 6.4) mm,(511.6 ± 26.7) m,(679.4 ± 51.3) μg/L,and there were significant difference compared with those before treatment (P ＜ 0.05).LVEF,LVEDD,6 min walk distance,BNP after treatment in observation group were respectively (51.6 ± 9.2)％,(51.2 ± 6.3) mm,(579.3 ± 25.1) m,(536.5 ± 50.6)μ g/L,and there were significant difference compared with those before treatment (P ＜ 0.05).There were significant difference in LVEF,LVEDD,6 min walk distance and BNP after treatment between two groups (P ＜ 0.05).The total effective rate in observation group was 90.7％ (39/43),which was significantly higher than that in control group [72.1％ (31/43)] (x2 =4.914,P ＜ 0.05).Conclusion Adding trimetazidine on the basis of conventional therapy can improve the cardiac function and myocardial remodeling of ACM patients and improve clinical efficacy.

Objective To investigate the relationship between the incidence of dysphagia and the location of brain lesions in patients with acute stroke.Methods Swallowing function was assessed by Watin drinking water test within 48 hours after admission in 226 cases with acute stroke.The location of the brain lesions was identified by CT and / or MRI.According to the US National Institutes of Health Stroke Scale (NIHSS),evaluation of nerve functions was evaluated within 24 hours after admission in stroke patients.Results The incidence of dysphagia was 50.4％ (114 /226) in 226 patients in acute stage.The degree of neurological deficit of stroke patients on admission was significantly correlated with the occurrence of dysphagia (x2 =13.35,P=0.02).The incidence of dysphagia caused by lesions in internal carotid artery trunk (hemisphere in combination with basal ganglia/internal capsule) was more common in anterior circulating territory(internal carotid artery system),dysphagia with internal carotid arterg(ICA) trunk occlusion (hemisphere in combination with basal ganglia/internal capsule) was more common than that caused by cortex branches occlusion (hemisphere-cortex) or penetrating ICA injuries (basal ganglia/internal capsule) and cortex branches occlusion (hemisphere-cortex),respectively(x2 =8.228,P＜0.05).The incidences of dysphagia induced by brain lesions of different cortex lobes had no statistic differences(x2 =0.312,P＞0.05).In posterior circulating territory (vertebro-basilar system),the incidence of swallowing disorders was significantly higher in brain stem group than in the thalamus and cerebellum (x2 =27.292,P＜0.001).The incidence of the dysphagia caused by lesions in cerebral hemispheres,combined basal ganglia / internal capsule and brain stem lesions were significantly higher than those caused by other lesions(x2 =35.639,P＜0.000).Conclusions Brain lesions of hemisphere combined basal ganglia/internal capsule and brain stem are significantly associated with the occurrence of dysphagia after acute stroke.
