Clinical data of 62 children with dilated cardiomyopathy (DCM)admitted to hospital from January 1998 to December 2008 were retrospectively analyzed. The age of patients was from 14 months to 14 year with the average of 8. 2 years. Respiratory infection was the main triggering factor. Cardiac dilatation was the basic conditions for diagnosis of DCM. Arrhythmia was characteristic for DCM, and color cardio uhrasonography was an important procedure of diagnosis and evaluation for cardiomyopathy. With the integrated treatment 38 cases were discharged with improvement ( 61% ), 11 cases died ( 18% ). Early diagnosis and integrated treatment are critical for management of cardiomyopathy in children.

The clinical data of 76 children with EFE admitted from June, 1998 to December, 2009 was retrospectively analyzed. Tachypnea、 cough and cyanosis were common and all presented with heart failure. Electrocardiogram revealed sinus tachycardia 、left ventricular hyperthrophy and ST-T alterations. On chest radiograph 54 cases (54/76) had a cardiothoracic ratio ＞ 0. 65 and 33 with pneumonia.Echocardiopraphy revealed lowered left ventricular systolic function in all cases and decreased left ventricular diastolic function in 21 (21/76). 63 cases (63/76) presented with thickened and enhanced left ventricular endocardium and 11 (11/76) with thickened interventricular septals. All were treated with digitalis. 58children were improved and discharged, 10 gave up therapy and 8 died during hospitalization. 41 out of 58 improved cases were followed for 1 - 4 years, with 2. 6 years on average. Among them 28 were clinically cured, 7 deteriorated and 6 died of heart failure. Echocardiography is of diagnostic value for ERE. Systolic and diastolic function of the heart can be used to predict the outcome. Pulmonary infection is a major risk factor associated with deterioration. Long-term treatment is imperative to improve the prognosis.

ObjectiveTo explore the effect of dressing-pretreatment on forepart inflammation in adjuvant arthritis (AA) rats.MethodsAA model was established by subcutaneous injection of Freund's complete adjuvant into the right hind-paw (0.1 ml/animal). 24 Wistar rats were randomly divided into the control group, model group and dressing-pretreatment groups. In dressing-pretreatment group, "Dazhui" (GV14) was applied by a kind of dressing invented by the researchers. The foot swelling rate, serum concentrations of interleukin-1 (IL-1), IL-6 and tumor necrotic factor-α (TNF-α) were assessed.ResultsCompared with the control group, the foot swelling rate and serum concentrations of IL-1, IL-6 and TNF-α of the model group and dressing-pretreatment group increased significantly (P<0.01); but the foot swelling rate and serum concentrations of IL-1 and IL-6 in dressing-pretreatment group decreased significantly compared with those of the model group (P<0.05～0.01), and there was a downtrend in TNF-α. HE stain showed soakage of phlogistic cell in cartilage and arthritis membrane, hyperplasia of vein and breakage of cartilage were better in dressing-pretreatment group compared with that in the model group.ConclusionDressing-pretreatment can decrease forepart inflammation and pathological damage of arthritis in AA rats, and can prevent the harm of consequent disease to some extent.

Objective:To observe the effect of marine capsules on BALB/c human hepatocellular carcinoma cell line SMMC-7721 in vitro. Methods:Human hepatoma SMMC-7721 cell line was cultured in vitro to establish a hepatoma tumor model, and was random-ly divided into the model control group, 5-Fu group (25 mg·kg-1), marine capsules high dose group (90 mg·kg-1), marine cap-sules low dose group (45 mg·kg-1 ) and the blank control group with 10 mice in each and 14-day continuous administration. Blood was taken from the eyeball and serum was isolated. The tumor strains were picked, the wet weight was obtained, the inhibition rate was calculated, and the pathological changes of tumor tissues were observed after HE staining. Results: Compared with that in the model control group, the serum IL-2 content significantly increased in the marine capsules high and the low dose groups ( P<0. 01, P<0. 05). The in vitro growth of tumor (P<0. 001, P<0. 05) was inhibited with the inhibition rate of 41. 56% and 27. 78% respectively for the high dose group and the low dose group, and the effects of the high dose group had no significant differences with those of 5-Fu group (P>0. 05). The nuclear staining of tumor cells was lighter and the number of tumor cells decreased in the two marine capsules groups. Conclusion:Marine capsules have certain inhibitory effects on BALB/c human hepatocellular carcinoma cell line SMMC-7721 in vitro.

ObjectiveTo observe the effect of dressing and moxibustion-pretreatment on the local joint swelling and stress hormone in hypothalami of rats with adjuvant arthritis (AA) at early and secondary stages.MethodsForty Wistar rats were randomly divided into 5 groups: normal group, early and secondary model groups, early and secondary pre-dressing and moxibustion (PDM) groups. The dressing with Chinese herb and moxibustion was stuck on Dazhui point (GV14) before the AA model established. The effects of dressing and moxibustion-pretreatment on the feet swelling and corticotropin-releasing-hormone (CRH), beta-endorphin (β-EP) and neuropeptide-Y (NPY) in hypothalami were observed.ResultsThe right feet swelling rate at early and secondary stages obviously increased after modeling ( P<0.01), and it became lower in early and secondary PDM groups than in model groups at the same phases ( P<0.05～0.01). The level of hypothalamic CRH was higher after modeling ( P<0.05～0.01), compared with early model group, it had a tendency to going down in early PDM group, moreover, in secondary PDM group the level was similar with the normal group. The level of hypothalamic β-EP increased significantly in early model group ( P<0.01), and lightly changed in secondary model group, it decreased in early PDM group but increased in secondary PDM group, compared with model groups at the same stages ( P<0.05). The level of hypothalamic NPY increased significantly after modeling, and it declined in the secondary PDM group ( P<0.05).ConclusionDressing and moxibustion-pretreatment can relief feet swelling of AA rats, which may be related with its regulative effect on the level of hypothalamic CRH, β-EP and NPY.
