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.

OBJECTIVETo investigate the characteristics of pain in temporomandibular disorders (TMD) through analyzing the description of pain by the TMD patients.

METHODSNinety TMD pain patients were included and the glossary in description of the intensity, rhythm and degree of disability due to TMD pain were recorded.

RESULTSThe descriptive pain by 90 patients was slight to moderate. There was no significant difference between males and females or between chronic and acute patients in the description of pain intensity (P > 0.05). The chewing disability was the most often reported complaining, and then was mental status. The probability of pain at rest was not different between in chronic pain patients and acute pain patients(P > 0.05). The acute pain patients often used aching, slight and tingle to describe their pain, while the chronic pain patients used dull, gas and numb more.

CONCLUSIONPain intensity in acute or chronic TMD patients is both low. The pain mainly influences chewing function and mental status in patients. Descriptive characteristic with chronic orofacial pain is different from acute.

OBJECTIVETo investigate the biological effects of ultraviolet B (UVB) irradiation on human bronchial epithelial cells (16HBE cells) and explore the possible mechanism.

METHODSThe survival rates of 16HBE cells were detected by MTT assay at 12 h after UVB irradiation at different doses (0, 10, 30, 50, 70, and 100 J/m(2)) or at 50 J/m(2) for different durations (2, 4, 8, 12, and 24 h). The DNA ladder was detected by agarose gel electrophoresis, the cell cycle changes were analyzed by flow cytometry, and the expression of nuclear factor-κB (NF-κB)/p65 protein was assayed by Western blotting following the exposures.

RESULTSUVB irradiation of the cells resulted in lowered cell survival rates, DNA fragmentation, S phase arrest and up-regulation of NF-κB/p65 protein expression.

CONCLUSIONSUVB irradiation can induce growth inhibition and apoptosis of 16HBE cells, in which process NF-κB protein may play a key role.
