Objective To evaluate the non-invasive cardiac output measurements by electric impedance in critically illpatients. Methods Cardiac output measurements by impedance and Doppler ultrasonography were performed in 38 pa-tients in ICU. Results There was a significant correlation (r =0. 908 ) between impedance and ultrasonography for car-dio output measurement. Conclusion There is close agreement between electric impedance and ultrasonography in themeasurement of cardiac output in the patients. The electric impedance measurement is a noninvasive,feasible, handy, con-tinuous and cheap measurement of cardiac output.

Objective To study the prognosis of polymyositis(PM) and dermatomyositis(DM) patients and its influence factors.Methods Sixty DM and 30 PM patients diagnosed according to the diagnostic criteria of Bohan and Peter in our hospital during 2000-2008 were used as study subjects.The patients were followed up till their death or to August 2009.Gender,age of disease onset,disease course,serum creatine kinase,interstitial lung disease,heart involvement,connective tissue disease(CTD),malignancies,and treatment with corticosteroids,immunoglobulin and immunosuppressive agents were assessed as predictive factors for the prognosis of patients.Characteristics of muscular biopsy from 20 cases were analyzed.Results The median age of the 90 patients(29 males and 61 females) was 51 years(range 6-74 years).The male and female ratio was 1∶2.The most commonly involved muscles were the proximal muscles of limbs(83.3%),followed by neck muscles(25.6%),laryngea pharyngeal muscles(12.2%) and masticatory muscles(2.2%).Among the 42 patients(46.7%)with lung disease,interstitial lung disease and hear involvement were found in 29(32.2%)and 13(14.4%)patients,respectively.Of the 13 patients complicated by connective tissue disease,DM and PM accompanying connective tissue disease were diagnosed in 9 and 4,respectively,and DM and PM accompanying malignancies were observed in 2 patients.Muscular or skin biopsy was performed for 23 patients,which showed typical inflammatory infiltration in 13,dermatomyositis in 3,and no significant lesion in 2 patients,respectively.Of the 18 patients who died during the follow-up,5(16.67%) and 13(21.67%) died of PM and DM,respectively.Seventy-two patients survived.Their 1-,5-,and 9-year survival rate was 90%,84.4%,and 80%,respectively.The complete and partial remission rate was 22.2% and 36.7%,respectively,with a relapse rate of 20%.Advanced age of disease onset(P=0.003 8),interstitial lung disease(P=0.011 3) and malignancies(P=0.004 9) were main causes of death.Malignancy(RR=6.34,P=0.001 2)was the factor for poor prognosis and long-term treatment with hormones and immunosuppressive agents is the protective factor for PM and DM.Conclusion Complete and partial remission can be achieved in 58.9% patients with DM and PM.Advanced age of disease onset,interstitial lung disease and malignancy are the factors for poor prognosis of such patients.Long-term treatment with corticosteroids and immunosuppressive agents are the protective factors.

Objective:To analyze the clinical manifestations, skeletal muscle pathology, electromyography, skeletal muscle magnetic resonance imaging and gene mutations of a family with distant-onset DnaJ (heat-shock protein 40) homolog subfamily B member 6 (DNAJB6) myopathy.Methods:A total of three generations with three cases of the disease in a family, inherited by autosomal dominant inheritance, were collected. The examination of muscle enzymes, left biceps biopsy, skeletal muscle magnetic resonance imaging (MRI) and electromyography, etc,were performed for the family 's proband. Whole-exon sequencing was performed to screen the proband for pathogenic genes, and Sanger sequencing technology was performed to verify mutation sites of the proband′s family members. Results:The proband is a 30-year-old male who began to show weakness in the distal muscles as a teenager, and then gradually developed to the proximal muscles, accompanied by muscle atrophy of the limbs, mainly affecting small muscles in the hands and distal muscles of the lower limbs. Muscle enzymes of the proband were slightly elevated. Skeletal muscle MRI indicated muscle atrophy and fatty degeneration in the proximal and distal extremities, which in the distal extremities were more severe, mainly affecting the muscle groups of the posterior group. Electromyography indicated chronic myopathic damage. Muscle pathology suggested chronic muscle fiber damage and rimmed vacuoles could be found. The proband was found a heterozygous mutation [c.298T>G(p.F100V)] in DNAJB6 gene by all-exon sequencing. Sanger sequencing confirmed that his brother (similar medical history) and the second daughter also had the same mutation, and the eldest daughter was not detected the mutation at the above site. The second daughter is not ill and is a carrier of the mutation. The father of the proband died of pancreatic cancer and had similar symptoms during his lifetime.Conclusions:The above mutation of DNAJB6 gene is the pathogenic gene of this family. The clinical features are adolescence-onset muscle weakness and atrophy in distal extremities. This is the first family report of distal-onset DNAJB6 myopathy caused by mutations at this site in China.

Objective To investigate relationship between utrophin and dystrophin in muscle of patients suffered from several neurological muscular diseases.Methods Muscle biopsies of 26 cases of patients suffered from 8 categories neurological muscular diseases and 2 cases of control were analysed for utrophin and dystrophin by immunofluorescence experiments.Results In a majority of Duchenne muscular dystrophy (DMD) patients,their sarcolemma revealed absent,weak or discontinuous fluorescence for dystrophin.In non-DMD muscular dystrophies,lipid storage myopathy,myotonic dystrophy,inflammatory myopathies, neurogenic amyotrophy, polymyositis, mitochondrial encephalomyopathy, myogenic amyotrophy,immunofluorescence reactivity for dystrophin were strongly exhibited in entire sarcolemma.In normal biopsy sample,strong immunofluorescence reactivity for dystrophin was identified in entire sarcolemma,while weak and discontinuous fluorescence was identified on a minority of sarcolemma of DMD patients with severely reduced dystrophin.There was no immunofluorescence reactivity for utrophin in sarcolemma of DMD patients with moderate decreased dystrophin,non-DMD muscular dystrophies and other 6 categories of neurological muscular diseases,nor in sarcolemma of normal biopsies.Conclusions utrophin is expressed in sarcolemma of DMD patients,who have severely reduced dystrophin simultaneously. utrophin is absent in sarcolemma of other categories of neurological muscular diseases including non-DMD muscular dystrophies with normal dystrophin expression and DMD patients with moderately decreased dystrophin.
