Vaginal intraepithelial neoplasia (VAIN) is often found by chance. We investigated the prevalence of VAIN and related human papillomavirus (HPV) types in comparison with cervical intraepithelial neoplasia (CIN). This study enrolled 648 women who were referred to the outpatient clinic determined using Genosearch-31 + 4, which can detect 35 different HPV types.Colposcopy was performed at the first visit by an experienced gynecological oncologist. Among 611 subjects with squamous cell lesions, 107 (17.5%) VAIN cases were identified, and 67 (11.0%) women had both VAIN and CIN. Ultimately, 72 VAIN1, 15 VAIN2/3, 203 CIN1, 249 CIN2/3, 32 cervical squamous cell carcinomas (SCC), and one vaginal SCC (Vag-SCC) were identified. The prevalences of VAIN1, VAIN2/3, and Vag-SCC were 35.5%, 6.0%, and 3.1% of equivalent cervical lesions, respectively. The VAIN patients were older than the CIN patients (P = .002). About half of the VAIN cases were diagnosed during the follow-up. Multiple HPV infections were found in 42.9% of the VAIN and CIN patients. HPV52,16, 51, 53, and 56 were the most common types in VAIN, whereas HPV16, 52, 58, 51, and 31 predominated in CIN. HPV18 was rare in VAIN, HPV58 was more common in CIN than in VAIN, and HPV53 and HPV73 were more common in VAIN. In conclusion, VAIN1 was identified more frequently than we expected. Various HPV types were identified in the vagina, which is likely a reservoir for HPV.

Overexpression of Crk-like (CrkL) adapter protein has been implicated in a number of types of human cancer. However, its involvement in human cervical carcinoma remains unclear. The present study aimed to explore the clinical significance and biological characteristics of CrkL in human cervical carcinoma. CrkL protein expression was examined in tissue samples from 92 cases of cervical carcinoma using immunohistochemistry, and was found to be overexpressed in 48.9% (45/92 cases). CrkL was transfected into HeLa and CaSki cervical carcinoma cell lines and its effects on biological behavior were examined. CrkL overexpression was revealed to promote cell proliferation, invasion and chemoresistance. In addition, CrkL overexpression increased the level of Src and Akt phosphorylation. Treatment with the Src inhibitor dasatinib eliminated the effect of CrkL on cell invasion. In conclusion, the current results demonstrate that CrkL is an oncoprotein overexpressed in cervical carcinoma which contributes to malignant cell growth and chemoresistance. In addition, the findings indicate that CrkL promotes cervical cancer cell invasion through a Src-dependent pathway.

The incidence of uterine fibroids, which comprise one of the most common female pelvic tumors, is almost 70-75% for women of reproductive age. With the development of surgical techniques and skills, more individuals prefer minimally invasive methods to treat uterine fibroids. There is no doubt that minimally invasive surgery has broad use for uterine fibroids. Since laparoscopic myomectomy was first performed in 1979, more methods have been used for uterine fibroids, such as laparoscopic hysterectomy, laparoscopic radiofrequency volumetric thermal ablation, and uterine artery embolization, and each has many variations. In this review, we compared these methods of minimally invasive surgery for uterine fibroids, analyzed their benefits and drawbacks, and discussed their future development.

<b><i>Introduction:</i></b> This study aimed to evaluate whether endometriosis could disturb the mental health and health-related quality of life (HRQoL) of patients and to provide a new prospective for further treatment of endometriosis. <b><i>Methods:</i></b> A comprehensive literature review was conducted among 4 international databases (PubMed, Embase, Web of Science, and Cochrane Library) and 2 of the largest Chinese databases (the China National Knowledge Infrastructure and Wangfang). The Newcastle-Ottawa Scale was used to assess the quality of the included articles. Six effect sizes were synthesized through a meta-analysis, and a subgroup analysis was performed to identify potential moderating factors, including types of control groups, methods of assessment, number of study groups, and origin of the study. Potential publication bias was examined using a funnel plot. <b><i>Results:</i></b> This meta-analysis pooled 44 articles from 4 continents and 13 countries and compared 6 types of main effect sizes (the odds ratio [OR] for depression, the OR for anxiety, the standardized mean difference [SMD] for depression, the SMD for anxiety, the SMD for the physical component summary [PCS] and the SMD for the mental component summary [MCS]) between endometriosis patients and controls. Except for the SMD for depression, all other effect sizes revealed statistically significant differences between the study group and the controls. The main effect size outcomes of the subgroup analysis were also similar. The type of control group (<i>I</i>² = 35% in non-endometriosis control groups for the SMD of anxiety; <i>I</i>² = 47% in non-endometriosis control groups for the MCS of the 36-Item Short Form Health Survey) and the continent of origin (<i>I</i>² = 0% in studies from South America for the OR of depression; <i>I</i>² = 47% in studies from Europe for the SMD of anxiety) may influence heterogeneity in this analysis. Additionally, depression and anxiety symptoms in patients seemed to be more apparent compared with healthy controls when the sample was smaller and when a questionnaire was used. The publication bias of the articles was acceptable. <b><i>Conclusion:</i></b> Endometriosis can disturb mental health (specifically depression and anxiety) and decrease both the mental and physical HRQoL of patients. There may be some moderating factors that we were unable to identify in the subgroup analysis, but more research is necessary to develop proper management and improve the prognosis of endometriosis patients.
