Polycystic ovary syndrome (PCOS) is a common disease in women, affecting women's menstruation and significantly impacting women's physical and mental health. Studies have shown that insulin resistance has an important relationship with polycystic ovary. It is of great significance to explore the changes of inflammatory factors, oxidative stress, glucose and lipid metabolism, and insulin resistance in patients with PCOS. In the study process, 642 polycystic ovary patients in the first half of 2019 were divided into insulin resistance (n=357) and non-insulin resistance (n=285) groups. Oxidative stress index, glucose, and lipid metabolism index, and inflammatory factors were detected during the study process. The results showed that the levels of hs-CRP, TNF- α, and IL-6 in the IR group were 5.9mg/L, 9.2μg/L, and 87.2ng /ml, while those in the non-IR group were 4.6mg/L, 6.3μg/L and 51.5ng/ml, respectively. Thus, IL-6 and insulin levels maintain a dynamic balance. Low levels of IL-6 can promote insulin secretion, while high levels can inhibit its secretion. The results of this study will provide a specific clinical reference value for the prevention and treatment of polycystic ovary syndrome.
Background Mixed cell ovarian adenocarcinoma (MCOA) is a malignant gynecologic tumor consisting of serous, mucous, and papillary tumor cells. However, the clinical features and prognosis of MCOA patients are unclear. Methods In this study, univariate and multivariate Cox proportional risk models were performed to identify independent prognostic factors. The Kaplan–Meier method was used to assess the relationship between clinical characteristics and patient survival. Finally, a nomogram was constructed and validated to predict patient survival time, and the C-index was used to evaluate the efficacy of the nomogram. Results A total of 2,818 patients diagnosed with MCOA were identified, and the 5-year survival rate was 62%. Univariate and multivariate Cox models suggested that age (HR=1.28, 95% CI[1.15,1.44]), grade (HR=1.26, 95% CI[1.12,1.41]), SEER stage (HR=1.63, 95% CI[1.25,2.13]) and AJCC (American Joint Committee on Cancer) stage (HR=1.59, 95% CI[1.36,1.86]) were independent prognostic factors for MCOA patients. After propensity score matching for age, grade, SEER stage, and AJCC stage, the 5-year survival rate was 69.7% for ovarian serous cystadenocarcinoma and 62.9% for ovarian papillary serous cystadenocarcinoma. These results mean that serous adenocarcinoma had the best prognosis of the three pathologic types of ovarian carcinoma (p<0.0001), with no significant difference between papillary serous cystadenocarcinoma and MCOA (p=0.712). Finally, a nomogram consisting of age, grade, SEER stage, and AJCC stage was established and validated to predict the survival time, with C-indices of 0.743 and 0.731, respectively. Conclusions In summary, MCOA is uncommon, and age, grade, SEER stage, and AJCC stage are independent prognostic factors. Compared with other common malignant ovarian tumors, MCOA has a poor prognosis.
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.
