BackgroundAdenomyomectomy has recently been considered the priority option for the treatment of adenomyosis, however, the surgical efficacy and modes are still debated. We aimed to evaluate the efficacy of laparoscopic adenomyomectomy using a double-flap method for the treatment of uterine diffuse adenomyosis when compared with conventional laparoscopic adenomyomectomy.MethodsLaparoscopic adenomyomectomy using the conventional method (group A, n = 48) and the double-flap method (group B, n = 46) to treat diffuse uterine adenomyosis, respectively. Visual analog scale (VAS), menstrual amount, serum CA125 levels, and uterine volume were comparatively analyzed in both groups.ResultsThe VAS scores, menstrual amount, serum CA125 levels, and uterine volume at 12 or 24 months after surgery significantly reduced in group B than in group A (P < 0.05); these parameters were statistically decreased in both groups after surgery compared with those obtained before surgery (P < 0.001). Moreover, serum CA125 levels and uterine volume at six months of follow up were significantly lower in group B than in group A (P < 0.01). In addition, blood loss during surgery was similar in groups A and B (P > 0.05), although the operative time was significantly longer in group B than that in group A (P < 0.05).ConclusionsLaparoscopic adenomyomectomy using the double-flap method may be an effective technique to treat uterine diffuse adenomyosis.
ABSTRACT. High-altitude pulmonary edema (HAPE) is a lifethreatening condition caused by acute exposure to high altitude. Accumulating evidence suggests that genetic factors play an important role in the etiology of HAPE. However, conclusions from association studies have been hindered by limited sample size due to the rareness of this disease. It is known that mitochondria are critical for hypoxic adaptation, and mitochondrial malfunction can be an important factor in HAPE development. Therefore, we tested the hypothesis that ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 11 (4): 3658-3667 (2012) Mitochondrial haplogroup and HAPE susceptibility 3659 mitochondrial DNA haplotypes and polymorphisms affect HAPE susceptibility. We recruited 204 HAPE patients and 174 healthy controls in Tibet (3658 m above sea level), all Han Chinese, constituting the largest sample size of all HAPE vulnerability studies. Among mtDNA haplogroups, we found that haplogroup D4 is associated with resistance to HAPE, while haplogroup B is a genetic risk factor for this condition. Haplogroup D4 (tagged by 3010A) may enhance the stability of 16S rRNA, resulting in reduced oxidative stress and protection against HAPE. Within haplogroup B, subhaplogroup B4c (tagged by 15436A and 1119C) was associated with increased risk for HAPE, while subhaplogroup B4b may protect against HAPE. We indicate that there are differences in HAPE susceptibility among mtDNA haplogroups. We conclude that mitochondria are involved in adverse reactions to acute hypoxic exposure; our finding of differences in susceptibility as a function of mitochondrial DNA haplotype may shed light on the pathogenesis of other disorders associated with hypoxia, such as chronic obstructive pulmonary disease.
Background: To determine whether a specific mitochondrial DNA (mtDNA) haplogroup is implicated in the pathogenesis of intrauterine adhesion (IUA). Methods: Peripheral blood samples were collected from 486 women with (case group, n = 154) and without IUA (control group, n = 332) at the Women's Hospital, Zhejiang University School of Medicine. Genomic DNA was extracted from the blood, and the mtDNA haplogroups of Han women M, N and R were determined by sequencing hypervariable mtDNA segments and testing diagnostic polymorphisms in the mtDNA coding region. Results: Women with mtDNA haplogroup R had an independently increased genetic risk factor for IUA with an OR 1.77 (95% CI 1.16-2.70, p = 0.009) compared with women without. Moreover, repeated intrauterine surgery within 1 month and number of intrauterine operations were both significantly associated with IUA (p < 0.001). Conclusions: These results suggest that mtDNA haplogroup R, one of the main mtDNA haplogroups in Han population, is a strong independent genetic risk factor for women with IUA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
