Objective The aim of this study was to explore the acceptance and influencing factors of self-collected urine samples for human papillomavirus(HPV)testing in cervical cancer screening among eligible women,and to provide scientific evidence for promoting this testing in low resource areas.Methods A population-based cross-sectional study was conducted from 2022 to 2023 at the Maternal and Child Health Hospital in Shuangliu district,Chengdu City Sichuan Province.The study subjects were women aged 21 to 69 years old,and a customized questionnaire was used to conduct general information and acceptance surveys on the partic-ipants.Results A total of 2,062 women were included,with an average age of 51.58±9.34 years.Among them,1,501(72.79％)women believed that self-sampling urine was very easy.However,although 1,333(64.65％)women were still willing to accept doctor sampling as a cervical cancer screening method,only 729(35.35％)were more willing to accept self-sampling urine HPV testing.Age,educational level,annual household income,awareness of HPV,HPV vaccination status,and a sense of shame about the doctor's sampling process were all associated with the acceptance of self-collected urine HPV testing among women undergoing cervical cancer screening(P＜0.001).The results of multivariate logistic regression analysis indicated that older women(OR=0.965,95％CI:0.951-0.979)and those who were not familiar with HPV(OR=0.760,95％CI:0.602-0.961)were more likely to undergo self sampling urine HPV testing,while those with junior high school education(OR=1.330,95％CI:1.053-1.682),high school education or a-bove(OR=1.990,95％CI:1.401-2.827),and a sense of shame towards the doctor's sampling process(OR=2.314,95％CI:1.706-3.142)were more likely to undergo self sampling urine for HPV testing.Conclusions Most women believe that self sampling urine for HPV testing is very easy,but compared to doctor sampling,only some women choose to self sample urine for HPV testing.Key health education interventions should be carried out for older and lower educated populations to promote acceptance of urine HPV testing.

INTRODUCTION: Dihydroartemisinin (DHA) is a first-line antimalarial drug with relatively low toxicity. DHA has been speculated to possess a broad-spectrum antitumour effect. However, the potential value of DHA for the treatment of endometrial carcinoma or cervical cancer is unclear. METHODS: We used human endometrial cancer cells and cervical cancer cells to assess whether DHA alone or when combined with cisplatin would induce cell death. We aimed to elucidate the role of autophagy in DHA-induced cytotoxicity in both endometrial and cervical cancer cells, and explore the impact of DHA treatment on cell proliferation, apoptosis and autophagy. RESULTS: DHA alone or in combination with cisplatin induced cell death in a dose- and time-dependent manner. Caspase-3 mRNA and cleaved caspase-3 protein levels were markedly elevated following DHA treatment either in the presence or absence of cisplatin, suggesting a role of apoptosis in DHA-induced cell death. DHA treatment activated the autophagic pathway, as evidenced by increased monodansylcadaverine-positive staining, elevated microtubule-associated protein 1 light chain 3 (LC3)-II/LC3-I ratio, and enhanced p62/sequestosome 1 degradation. Inhibition of autophagy by 3-methyladenine further enhanced the cytotoxicity of DHA towards tumour cells. mRNA levels of transferrin receptor (TfR) were suppressed upon DHA treatment and knockdown of TfR by RNA interference caused further DHA induction of cancer cell death. CONCLUSION Our results suggest a clinical value for DHA in the treatment of endometrial carcinoma and cervical cancer. Our data revealed possible anticancer mechanisms of DHA that involve regulating apoptosis, autophagy pathway and levels of TfR.

The outbreak of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 has rapidly spread globally. Cancer patients are at a higher risk of being infected with the coronavirus and are more likely to develop severe complications, as compared to the general population. The increasing spread of COVID-19 presents challenges for the clinical care of patients with gynecological malignancies. Concerted efforts should be put into managing gynecological malignancies in an orderly manner by strictly implementing the measures that are specifically developed for controlling the spread of COVID-19. We have drafted Recommendations on Management of Gynecological Malignancies during the COVID-19 Pandemic based on our experience on controlling COVID-19 pandemic in China. We recommend that patients with gynecological malignancies should be managed in hierarchical and individualized manners in combination with local conditions related to COVID-19. Medical care decision should be balanced between controlling COVID-19 pandemic spread and timely diagnosis and treatment for gynecologic oncology patients.

INTRODUCTIONC-X-C chemokine receptor type 7 (CXCR7) has recently been characterised as a novel receptor for the C-X-C motif chemokine 12 (CXCL12)/stromal cell-derived factor 1-alpha. CXCR7 has been thought to play an important role in the pathogenesis of chronic rhinosinusitis, angiogenesis and tumour metastasis. The present study aimed to examine the expression of CXCR7 in tissue samples of laryngeal cancer and maxillary sinus carcinoma to determine its role in the development of otorhinolaryngologic neoplasms.

METHODSSamples of otorhinolaryngologic neoplasms were obtained from 17 patients with either nasal polyps (n = 7), laryngeal cancer (n = 5) or maxillary sinus carcinoma (n = 5), and who underwent surgical resection at West China Hospital of Sichuan University. Total RNA was isolated and CXCR7 mRNA expression was examined and quantified by relative real-time reverse transcription polymerase chain reaction. A one-way analysis of variance was performed using SPSS Statistics version 11.0 (SPSS Inc, Chicago, IL, USA) to compare the CXCR7 mRNA levels among the three groups of patients.

RESULTSAll samples tested positive for CXCR7 mRNA. The quantitative results showed that the CXCR7 mRNA levels were highest in laryngeal cancer and lowest in maxillary sinus carcinoma neoplasms, although there was no significant difference among the three samples.

CONCLUSIONCXCL12 and its receptor CXCR7 may contribute to eosinophilic inflammation in patients with chronic sinusitis and nasal polyps. Our results also suggest that CXCR7 may play a role in the progression, metastasis and angiogenesis of otorhinolaryngologic tumours.

The teaching goal of the eight-year program of clinical medicine emphasizes on high standard,starting point and requirement. In order to improve the teaching quality of obstetrics and gynecology,the teaching faculties constantly introduced the most updated concepts from overseas into their teaching experience ,including the concepts of practical translational medicine ,using of English multimedia teaching materials, real case study and the communication skills between doctors and patients. It showed that efforts put in the reformation of teaching material improved the learning interests of students and the professional skills of teachers.
