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.

Objective To investigate the clinical features of initially treated pulmonary tuberculosis(TB)patients with rifampin dependent mycobacterium tuberculosis Rv0341 antibody positive.Methods Forty two initially treated pulmonary TB patients with rifampin dependent mycobacterium tuberculosis Rv0341 antibody positive were included as the study group and 42 initially treated pulmonary TB patients with rifampin dependent mycobacterium tuberculosis Rv0341 antibody as the control group The aspects of clinical symptoms,X-ray imaging manifestations,positive rate in sputum culture of Mycobacterium tuberculosis and rifampin dependent mycobacterium tuberculosis,treatment effects,etc.were compared between the two groups.Results The incidence rates of expectoration,hemoptysis and shortness of breath in the study group were significantly higher than those in the control group(P＜0.05);the X-ray image manifestations in the study group showed that the lesions were much more involved in two lungs and multiple lung fields(P＜0.05),while thlesions in the control group more confined to single lung and one lung field(P＜ 0.05),moreover the rate appearing pulmonary cavity in the study group was higher than that in the control group(P＜0.05);the sputum culture positive rate of Mycobacterium tuberculosis had no statistical difference between the two groups(P＞0.05),but the sputum culture positive rate of rifampin dependent mycobacterium tuberculosis in the study group was significantly higher than that in the control group(P＜0.05);as for the treatment effects,the cure rate in the control group was higher than that in the study group(P＜0.05),the ineffective ratio in the control group was less than that in the study group.Conclusion Initially treated pulmonary TB patients with rifampin dependent mycobacterium tuberculosis Rv0341 antibody positive have the characteristics of severe clinical symptoms,wide range lesions,easily appearing cavity,high culture positive rate of rifampin dependent mycobacterium tuberculosis and poor treatment effect.

OBJECTIVE To study the role of ciliary neurotrophic factor(CNTF) in the generation of facial nerve.METHODS Twenty adult New Zealand rabbits' bilateral super buccals of facial nerves were transected and connected with silicone tube.CNTF was injected into a random side of silicone tube and normal saline in the other.At four and eight weeks after the operation, both the CNTF group and the SAL group underwent electrophysiology test and histopathology as well as quantity analysis.RESULTS Four weeks later, both CNTF and SAL group failed in eliciting muscular excitement upon stimulation; T-test showed a signifi-cant difference(P

Objective To explore the influence of gentamycin on murine cochlea spiral ganglion neurons' electrophysiological properties and its significance.Methods Using whole-cell voltage clamp technique, we studied gentamycin's influence on the peak currents of the potassium and sodium ion channels on cell membranes of acutely dissociated murine spiral ganglion neurons,the relationship to gentamycin's concentration in extracellular fluid, and the currents' recovery after gentamycin being washed out.Results Gentamycin could inhibit voltage-dependent potassium channels, but it couldn't inhibit voltage-dependent sodium channels. Gentamycin's inhibitation on potassium currents had dose-dependence with gentamycin's concerntration in extracellular fluid and the currents recoverd incompletely after gentamycin being washed out.Conclusion This research explained the ototoxic mechanism of gentamycin through its action on keeping from spiral ganglion neurons' potassium ion channels from the electrophysiological aspect, and set a foundation for further research.
