ABSTRACT

Objective@#To investigate the concentration of serum bone resorption markers NTX and TRACP-5b of children aged 8-14 years in a coal-burning fluorosis area and its relationship with age, and to provide population data for the study of pathogenesis of skeletal fluorosis.@*Methods@#Totally 123 children of 8-14 schoolage in the two primary schools in Doujing Township, Shuicheng County, Liupanshui City, Guizhou Province were randomly selected as the exposed group. According to the matching principle, 64 children were randomly selected as a control from a primary school in a nondisease area Huaga Town. The dental fluorosis was investigated, and the concentrations of serum NTX and TRACP-5b were measured.@*Results@#The detection rate of dental fluorosis in the fluorosis area was 94.3% and 0 in the control area. The concentrations of serum NTX in fluorosis area children were 13.04 (10.76, 15.64), 14.82 (12.15, 18.26)nmol/L in the early adolescence and middle-aged period, which lower than the control area 15.73(14.36, 18.61), 16.45(15.45, 22.02)nmol/L( P <0.05); The serum TRACP-5b levels in children with fluorosis were 276.74(237.63, 312.75), 270.14(242.82, 321.97), 305.95(259.78, 339.87)nmol/L in prepubertal, early adolescence and middle youth, lower than the control area 370.88 (304.47, 452.84), 353.30 (262.05, 393.19), 420.22 (376.96, 544.60)nmol/L( Z =-3.03, -2.66, -3.10, P <0.05). Serum NTx and TRACP-5b in fluorosis area were negatively correlated with dental fluorosis in children( r =-0.51, -0.37, P <0.01).@*Conclusion@#Fluorosis can reduce the concentrations of serum bone resorption markers NTX and TRACP-5b in children of different age groups. TRACP-5b may be more sensitive to fluoride exposure than NTX, but the specific mechanism remains to be further studied.

ABSTRACT

Three new indole alkaloids, flueindolines A-C (1-3), along with nine known alkaloids (4-12), were isolated from the fruits of Flueggea virosa (Roxb. ex Willd.) Voigt. Compounds 1 and 2 are two new fused tricyclic indole alkaloids possessing an unusual pyrido[1, 2-a]indole framework, and 3 presents a rare spiro (pyrrolizidinyl-oxindole) backbone. Their structures with absolute configurations were elucidated by means of comprehensive spectroscopic analysis, chemical calculation, as well as X-ray crystallography. Chiral resolution and absolute configuration determination of the known compounds 4, 10, and 11 were reported for the first time. The hypothetical biogenetical pathways of 1-3 were herein also proposed.

ABSTRACT

Huntington disease (HD) is a chronic autosomal-dominant neurodegenerative disease. The gene coding Huntingtin has been identified, but the pathogenic mechanisms of the disease are still not fully understood. This paper reviews the involvement of mitochondrial dysfunction in pathogenesis of HD.

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the clinical experience from treatment of patients with severe acute respiratory syndrome (SARS).</p><p><b>METHODS</b>Retrospective analysis of seven patients with SARS in Ditan hospital treated since April 22 in 2004 was performed.</p><p><b>RESULTS</b>In the 7 patients, 2 were male, 5 were female, and the average age was (35.3 plus/minus 11.3) years. The main clinical manifestations were fever, cough, minor or serious dyspnea, nausea, signs of injury to other organs, and so on. The treatment regiments included oxygen, small dosage and short period of methylprednisolone (1 to 2 mg/kg), use of ventilator, psychological intervention, and treatment of underlying diseases, after which, all the 7 patients recovered.</p><p><b>CONCLUSION</b>Rational use of methylprednisolone and timely use of ventilator were the key steps of treatment.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effectiveness and mechanisms of molecular adsorbents recirculating system (MARS) treatment in severe liver failure patients with multiple organ dysfunction syndrome (MODS).</p><p><b>METHODS</b>60 single MARS treatments were performed for 6 - 24 hours on 24 severe liver failure patients with MODS.</p><p><b>RESULTS</b>MARS therapy was associated with marked reduction of albumin bound toxins and water soluble toxins, together with a significant removal of NO and certain cytokines, such as TNF-alpha, IL-6, IL-8, and INF-gamma. These were associated with a improvement of the patients' clinical conditions including hepatic encephalopathy, deranged hemodynamic situation, as well as renal and respiratory function, thus resulted into marked decrease of sequential organ failure assessment (SOFA) score (from 9.72+-1.89 to 6.98+-2.34), and improving outcome: 9 patients were able to be discharged from the hospital or bridged to successful liver transplantation. The overall survival rate of 24 patients was 37.5%.</p><p><b>CONCLUSIONS</b>There is positive therapeutic impact and safety to use MARS on liver failure patients with MODS. The effectiveness of MARS is correlated with reducing the levels of NO and cytokines, except for completely removing of accumulated toxins in liver failure patients.</p>
