Chinese Journal of Rheumatology 2001;0(01):-
Objective To investigate the role of sex hormones and interleukin (IL)-6 in the pathogenesis of primary Sjgren′s syndrome (pSS). Methods Serum specimen of 21 postmenopausal patients with pSS and 21 postmenopausal healthy women were collected. Serum estradiol (E2) and testosterone (Te) were estimated by the commercial radioimmunoassay kits, whereas serum dehydroepiandrosterone sulfate (DHEAS) were measured by enzyme-amplified chemiluminescence assay. Enzyme linked immunosorbent assay kits were used to determine levels of IL-6 in serum. Results The DHEAS and the Te level in serum were lower in postmenopausal patients with pSS than in healthy controls (P0.05). The level of IL-6 in pSS patients was higher than that in controls (P0.05). Conclusion Primary Sj(?)gren′s syndrome, in which an altered metabolism of sex hormones has occured, appears to be influenced by the change of the levels of sex hormones and IL-6 in serum.

Objective To investigate the character and location of a novel gene R049 and its expressed protein in uropathogenic Escherichia coli(UPEC) strain 132 isolated in China. MethodsThe chromosome library of UPEC132 was constructed by a shotgun strategy and the sequence analysis was carried out by a high-throughput pyrophosphate sequencing. Sequence reads were assembled with the Newbler program.The characters of R049-associated specific fragment were analyzed using the bioinformatics methods. Outer and inner membrane proteins of UPEC132 were extracted and then detected by SDS-PAGE and Western blot analysis together with the whole-cell lysates. ResultsThe 169 022 bp contig containing gene R049 was obtained and its sequence was very similar to the chromosome associated sequence of UPEC strain 536. It showed that a 20 773 bp fragment including R049 replaced the pathogenicity island PAI Ⅲ536 of UPEC536 in above 169 022 bp contig. The fragment had a lower GC content (46.97%) and 16 bp direct repeats in two ends. Significantly it also was adjacented to thrW tRNA, insertion element and genes coding integrase. Thus the 20 773 bp fragment was named R049 genome island(R049-GI). There were 25 ORFs in R049-GI, and gene R049 was located in the thirteenth ORF. The results of SDS-PAGE and Western blot revealed gene R049 encoded an outer membrane protein in the size of 47.0× 103. ConclusionGene R049, encoding an outer membrane protein, was a component part of the genome island in UPEC 132 chromosome acquired by horizontal gene transfer.

Objective To investigate the diagnostic accuracy and the clinical usefulness of the combination of troponin I (cTnI) and copeptin detected in patients with suspected non-ST elevation myocardial infarction. Methods 176 patients presenting to the emergency departments with chest chocking or chest pain within 6 hours and without ST elevation on a 12-lead electrocardiogram (ECG) were enrolled in this study. The level of copeptin and cTnI was measured. The diagnosis was adjudicated by 2 independent experts.The diagnostic performance of them was assessed using ROC analysis , and the sensitivity and specificity of them were inferred based on the positive rate of two cardiac markers. Results (1)The levels of copeptin and cTnI in NSTEMI patients were markedly higher than other groups (P<0.05).(2)The AUCs of copeptin and cTnI were 0.846 and 0.683, and the 95%CI of two markers were 0.786 ~ 0.906 and 0.577 ~ 0.789, respectively. (3)Using 10.85 pmol/L as cut off value,the sensitivity and specificity of copeptin were 90% and 64%,and the positive predictive value and the negative predictive valueof NSTEMI diagnose were 42.4% and 95.6%,respectively.Using 0.05 ng/mL as cut off value,the sensitivity and specificity of cTnI were 42.5% and 94.1%,the positive predictive value and the negative predictive value were 68%and 84.8% for diagnosis of NSTEMI. (4)The copeptin level over 10.85 pmol/L in combination with cTnI could be used to detect NSTEMI with higher sensitivity than that of copeptin or cTnI alone (95% vs 90% vs 42.5%). The negative predictive value of the combination of copeptin and cTnI was increased , compared to that of copeptin or cTnI alone (97.7% vs 95.6% vs 85.7%). Conclusions Determination of copeptin in addition to cTnI can improves diagnostic performance , especially early after chest pain onset. It seems to allow a rapid and reliable rule out of NSTEMI.

Neurodegenerative disease is characterized by progressive loss of neurons in specific brain regions that results in neuronal dysfunction of the central nervous system. Although the pathological mechanism is not fully established, the activation of glial cells mediated neuroinflammation appears to be involved. Heat shock protein 70 (HSP70) is originally described as intracellular chaperone, which plays an important role in protein quality control in cells. However, recent study showed that up-regulation of HSP70 had anti-inflammatory effects in the brain. HSP70 protected neurons from damage and improved neurological function by decreasing inflammatory response as indicated by inactivation of glial cells and inhibition of pro-inflammatory cytokine release. So it is of great significance to find new compounds targeting at HSP70 as neuroprotective agents to delay the progress of neurodegenerative disease. This review will focus on the role of HSP70 in neuroinflammation and the recent advances in using HSP70 as a target for the treatment of neurodegenerative disease.
