OBJECTIVE:To investigate the effects,prognosis and safery of recombinant human brain natriuretic peptide on the treatment of patients with acute decompensated heart failure. METHODS:90 inpatients with acute decompensated heart failure were divided into observation group and control group according to the use of recombinant human brain natriuretic peptide or not,with 45 cases in each group. Control group received rountine anti-heart failure therapy and intravenous dripping of Nitroglycerin injection at 20 μg/min continuously for 72 h. Observation group was additionally given Lyohilized recombinant human brain natriuretic peptide with initial loading amount of 1.5 μg/kg,iv,then intravenous dropping at 0.007 5 μg/(kg·min)continuously for 72 h,on the basis of control group. Hemodynamic parameters,brain natriuretic peptide level,the difference of liquid intake and output,dyspnea,lung rales,systemic edema,the improvement of cardiac function were observed and compared between 2 groups before and after treat-ment as well as re-hospitalization rate and surriral rate 30 d after medication,the occarrence of ADR. RESULTS:After treatment, left ventricular ejection fraction of observation group was significantly higher than that of control group,and central venous pressure and brain natriuretic peptide level were lower than those of control group,with statistically significance (P<0.05). The difference of liquid intake and output after treatment was (1 171.60 ± 444.80)ml in observation group and (822.30 ± 268.40)ml in control group,with statistical significance between 2 groups(P<0.05). After treatment,the scores of dyspnea,lung rales and systemic ede-ma were decreased in 2 groups;the improvement of observation group was significantly better than that of control group,with statis-tical significance(P<0.05). Total effective rates of observation group and control group were 95.56% and 82.22%;re-hospitaliza-tion rates 30 d after medication were 17.78%and 26.67%;survival rates 30 d after medication were 88.89%and 75.56%,with sta-tistical significance between 2 groups (P<0.05). There was no statistical significanse in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Recombinant human brain natriuretic peptide can significantly improve hemodynamic parameters and heart function of patients with acute decompensated heart failure,and effectively relieve dyspnea,lung rales and systemic edema. It is better than routine treatment in prognosis with good safety.

Objective Our aim is to study the clinical manifestation and endocrine disorder of the bulimia nervosa (BN). Methods 2 cases of BN were clinically analysed. Results Most of the patients were anorexia before the disease happened, with many aspects of endocrine disorders. Conclusions BN and amenorrea could result from hypothalamus function disorders. However, the alteration of corticoid,thyroid hormones may be results of emotion stress and body weight loss.

Tetraspanins belongs to the transmembrane 4 superfamily(TM4SF). They can be as a bridge to connect the proteins outside or inside the cell membrane. A tetraspanins web is formed by the tetraspnins-proteins complex, and the web is believed to involve in fundamental functions of immunity system, and consequnently, signaling between cells and inside cells, regulating cell activation and adhesion, participating in the identification and infection of some virus. As a family of conservative transmembrane proteins, tetraspanins play multiplex roles in invertebrate. It was described how tetraspanin microdomains might have functions in the immune system, and how they contact with virus. In addition, the important role of tetraspanins in the innate immune system of invertebrate were discussed.

Objective To compare the ability of CT and MRI in evaluating the residual of tumor of hepatocellular carcinoma (HCC) and its stability after treated by transcatheter arterial chemoembolization (TACE) with Lipiodol.Methods 28 patients with HCC underwent CT, MRI and angiography within 2～6 months after 1～4 procedure(s) of TACE. These three examinations were completed sequentially within one month. CT and MRI findings were thus compared on the basis of the results of arteriography and clinical follow-up at least 6 months.Results 46 lesions were found in 28 patients. 31 lesions with and the other 15 lesions without residual viable tumor were confirmed by arteriography and clinical follow-up. 20 lesions with and 26 lesions without residual viable tumor were found on CT images, and CT displayed 64.5% sensitivity, 100% specificity, and 76.1% accuracy respectively. 29 lesions with and 17 lesions without residual viable tumor were found on MRI images, and its sensitivity, specificity, and accuracy were 93.5%, 100%, and 95.7% respectively. The sensitivity and accuracy between CT and MRI in evaluating the residual viable tumor of HCCs after TACE were significant different(?
