To determine the ATPase activity of erythrocytic membrane and intraerythrocyticionic concentrations in 20 patients with chronic renal failure (CRF). Methods: Erythrocyte membrane AT-Pase activites were determined as described by Sha1ev, and erythrocyte Na+ and Ca2+ concentrations weredetected by atomic absorption spectrophotometry. Results: The Na+-K+-ATPase, Ca2 t -ATPase, Mg2+ATPase activities were significantly lower in CRF patients than in normal individuals (P

Objective To comparison of the quality of life in children with migraine and quality of life in children with primary epilepsy(EP)or Tourette's syndrome(TS).Methods There were 239 children with moderate migraine,the time of which lasted from 6 to 36(12.14?4.67)months,headache index 4-20(9.98?3.74).There were 250 cases and 424 cases with EP or TS,respectively,both team members were under good control with single drug therapy,the diagnosed according to the international classification of headache disorders-Ⅱ.The pediatric quality of life inventory,version 4.0,age 8-12 years,and child report forms were used to evaluate the quality of life in children with migraine and the other two kinds of samples by Bonferroni and Mann-Whitney tests.Results The scores of quality of life in children with moderate migraine were lower than those in children with EP(total score 69.06?10.48 vs 81.26?13.80;physical function scores 67.43?14.37 vs 83.14?14.70;psychological function scores 69.92?10.56 vs 80.26?14.32;emotional function scores 66.76?14.09 vs 80.90?18.93;social function scores 76.81?14.67 vs 83.36?17.40;school function scores 66.20?13.62 vs 76.52?13.80).The scores of quality of life in children with moderate migraine were lower than those in children with TS(total scores 69.06?10.48 vs 79.18?11.45;physical function scores 67.43?14.37 vs 81.52?12.61;psychological function scores 69.92?10.56 vs 77.90?12.28;emotional function scores 66.76?14.69 vs 74.07?16.34;social function scores 76.81?14.07 vs 89.06?16.23;school function scores 66.20?13.62 vs 70.35?16.96).Two sets of data between children with moderate migraine and those with EP,TS showed statistical significance(Pa

Objective To study the function of core protein (CORE) of genotype 1b hepatitis C virus (HCV) of different strains (T: derived from tumor tissues; NT: derived from non-tumor tissues; C191: HCV-J6) and different domains (1-172, 1-126, 1-58, 59-126, 127-172 AA) of T CORE in the pathogenesis of HCV infection and to find the therapy target. Methods Different truncated genotype 1b HCV CORE eukaryotic expression plasmids (T, NT, C191) and different domains of T CORE were constructed and transfected to HepG2 cells. Cell apoptosis and necrosis were quantified by flow cytometry. Cell growth curves were observed with real time cell growth instrument. Results COREs from different strains of genotype 1b and different domains of CORE induced cell apoptosis and necrosis, and inhibited HepG2 cell growth at different levels. CORE derived from T induced apoptosis and necrosis and inhibited cell growth higher than that derived NT and C191. N terminal 1-58 AA of CORE derived from T induced cell apoptosis and necrosis and inhibited cell growth higher than any other domains. Conclusion COREs from different strains of genotype 1b HCV and different domains of CORE from the same HCV strain play different roles in their molecular pathogenesis of HCV. Among different domains of CORE, N terminal 1-58 AA might play an important role in its pathogenesis and be one target of gene therapy.

Objective To explore the clinical characteristics and diagnostic criteria of migraine in children.Methods The migraine cli-nical characteristics of patients that consistent with the chronic headache diagnostic criteria, excluding other diseases,were analyzed.ICHD-Ⅱ childhood migraine diagnostic criteria was used as gold standard to explore the migraine diagnostic criteria in children.Results 1.In 346 patients, 157 fitted ICHD-Ⅱchildhood migraine diagnostic criteria.2.Type of migraine: probable migraine was the most common(68.8%), the most commonly unfulfilled criterion was associated gastroenteritis symptoms; migraine without aura was the second (19.7%).3.The migraine diagnostic criteria: the most important single-variable was headache associated symptoms,with sensitivity of 70.7%,specificity of 83.6%,the positive predictive value(PPV) was 78.2%,positive likelihood ratio (PLR) was 4.31 and area under curve(AUC) was 0.771.The most important three-variables was headache duration of 1-72 hours, moderate-severe headache and headache associated symptoms, with the sensitivity of 52.2%,specificity of 96.2%,the PPV was 90.1%, the PLR was 13.7 and the AUC was 0. 657.Conclusions The most important single-variable is headache associated symptoms,the most important three-variables are headache duration 1-72 hours, moderate-severe headache and headache associated symptoms.

Objective To investigate the relationship between the changes in serum lipoperoxide (LOOH) and nitric oxide (NO) levels and the pathogenesis of coronary heart diseases (CHD). Methods The concentrations of LOOH in the sera of 33 healthy subjects and 33 patients with CHD were determined by ferrous oxidation in xylenol orange (FOX) assay, while those of NO by enzymatic one-step assay with nitrate reductase. Results The average serum concentration of LOOH in the patients was (7.64±3.26) μmol/L, much higher than that of healthy subjects [(5.78±3.21) μmol/L, P<0.05]. The NO level was (42.5±18.9) μmol/L in the patients and (51.4±17.8) μmol/L in the healthy subjects, showing significant difference between the 2 groups (P<0.05). Conclusion The increased LOOH and decreased NO levels in the serum might be involved in the pathogenesis of arteriosclerotic heart diseases.

Ochratoxin A (OTA) is a toxic secondary metabolite mainly produced by Aspergillus and Penicillium species, existing in a variety of foodstuffs and Chinese medicines. OTA is difficult to be detected in practice because of the characteristics such as trace amounts, toxicity, existing in complex matrices. In the numerous detection technologies, colloidal gold chromatographic techniques are highly sensitive, specific, cost-effective and user-friendly, and are being used increasingly for OTA screening. Recently, with the development of aptamer technology and its application in chromatographic technique, a newly colloidal gold aptamer chromatographic technique has been developed. This review elaborates the structures and principles of both traditional and newly colloidal gold chromatographic techniques, focuses on newly colloidal gold aptamer chromatographic technique, summarizes and compares their use in rapid detection of OTA. Finally, in order to provide a reference for better research of related work, the development trends of this novel technique are prospected.
