Abstract：

Objective To study the distribution of human papilloma virus(HPV)subtypes in Uyghur people from the high risk region of cervical cancer in Xinjiang. Methods 21 subtypes of HPV from 400 cases of men's swabs of penile and 400 cases of women's cervix swabs were detected, using flow-through hybridization and gene chip technology. Results(1)The positive rate of HPV among the 400 women cases was 14.25% ,with HPV16 the most common type. In women whose HPV was positive, the positive rate of HPV16 was 66.67%. The ranking of frequencies on the HPV subtypes in women were: HPV 16, 58,39, 18,33,52,43,66, CP8304, HPV6 and 11.(2)Among the 400 male cases, the positive rate of HPV was 8.00%, with HPV16 the most common type. In men whose HPV was positive, the rate of HPV16 was 44.44%. The ranking of HPV subtypes in men were HPV16, 43, 33, 39, 6(HPV39 and 6 are equivalent)and 53.(3)Both wives and husbands were infected by different subtypes of HPV, the positive rate was relatively low among men whose wife's HPV were positive. However, the HPV positive rate was relatively low among women whose husband's HPV were positive. The concordance infection rate of women and men were 7.02% and the concordance infection rate of men and women were 9.38%. Conclusion The HPV positive rates were relatively low in both men and women living in the region with high risk of cervical cancer in Xinjiang. However, the positive rate of high risk types HPV and HPVI6 in both men and women were relatively high. Uyghur men seemed to have played a certain role related to the carcinogenensis of cervical cancer. HPV16 was the main type in both men and women in Xinjiang.

Mitochondrial metabolism related markers GDF-15, FGF-21, and HIF-1α are elevated in pediatric migraine attacks

Objective

The purpose of this study was to investigate the serum levels of mitochondrial metabolism/reactive oxygen species (ROS)–related peptides (hypoxia inducible factor-1α [HIF-1α], fibroblast growth factor-21 [FGF-21], growth differentiation factor-15 [GDF-15]) and key migraine-related neuropeptides (calcitonin gene–related peptide [CGRP], pituitary adenylate cyclase-activating peptide-38 [PACAP-38], substance P [SP], and vasoactive intestinal peptide [VIP]) during migraine attacks and to evaluate their diagnostic value in pediatric migraine.

Background

There is increasing evidence for the important role of impairment in oxidative mitochondrial metabolism in the pathophysiology of migraine. Potential biomarkers that may reflect the relationship between migraine and mitochondrial dysfunction are unclear.

Methods

A total of 68 female pediatric migraine patients without aura and 20 female healthy controls aged 8–18 years, admitted to the hospital, were enrolled in this cross-sectional study. Serum concentrations of these molecules were determined by enzyme-linked immunosorbent assays, and clinical features and their possible diagnostic value were analyzed.

Results

Serum levels of HIF-1α (252.4 ± 51.9 [mean ± standard deviation]) pg/mL), GDF-15 (233.7 ± 24.7 pg/mL), FGF-21 (96.1 ± 13.1 pg/mL), CGRP (44.5 ± 11.3), and PACAP-38 (504.7 ± 128.9) were significantly higher in migraine patients compared to healthy controls (199.8 ± 26.8, 192.8 ± 20.7, 79.3 ± 4.1, 34.1 ± 3.5 and 361.2 ± 86.3 pg/mL, respectively). The serum levels of these peptides were also higher in patients with chronic migraine than in patients with episodic migraine, and higher in the ictal period than in the interictal period. A positive correlation was found between attack frequency and both HIF-1α and FGF-21 levels in migraine patients. Serum levels of VIP and SP were not different between the migraine patients and healthy controls.

Conclusion

Migraine attacks are accompanied by elevated HIF-1α, FGF-21, GDF-15, CGRP, and PACAP-38 in medication-naive pediatric patients with migraine. Elevated circulating mitochondrial metabolism/ROS-related peptides suggest a mitochondrial stress in pediatric migraine attacks and may have potential diagnostic value in monitoring disease progression and treatment response in children. Novel approaches intervening with mitochondrial metabolism need to be investigated.
