OBJECTIVE: To evaluate the genital human papillomavirus (HPV) infection in patients from gynecology clinic, and to investigate the association of persistent HPV infection with cervical lesions. METHODS: From January, 2009 to December, 2013, clinical data of 16 320 patients in Third Xiangya Hospital were collected. A retrospective analysis was carried out to evaluate the overall prevalence of HPV infection. The prevalence of HPV infection in different ages and subtypes were compared. The prevalence of persistent HPV infection and results of cervical cytology were analyzed. RESULTS: The overall HPV prevalence was 26.54%. The lowest overall and high-risk HPV prevalence were found in women at the age of 30-39 years old (P<0.05); the highest ones were found at the age of over 60 years old, with significant difference among the aged groups (P<0.05). There was no significant difference in low-risk HPV prevalence among the aged groups (P=0.693). The clearance rate of HPV was 87.65% one year later. There was no significant difference in high-risk and low-risk HPV infection between the non-persistent positive group and the persistent positive group (P=0.545), but the difference in single and multiple subtypes infection between these 2 groups was significant (P<0.05). In the persistent positive group, the most common genotypes were HPV 16, 52, 58, CP8304, and 33. The incidence of ASC-US, HSIL or SCC was significantly increased in the persistent positive group. CONCLUSION Persistent HPV infection mainly consists of multiple and high-risk HPV infection. It is necessary to focus on the prevention of HPV 16, 52 and 58 persistent infection in our region.

Objective To discuss the feasibility, safety and validity of the use of ViabahnTM self-expanding covered stent in endovascular repair of peripheral traumatic pseudoaneurysm (TPA). Methods During the period from June 2012 to April 2014, a total of 8 patients with peripheral TPA were admitted to the Department of Vascular and Endovascular Surgery of Shanghai Changzheng Hospital . The clinical data were retrospective analyzed. The lesions were located at the common carotid artery (n=4), vertebral artery (n=1), subclavian artery (n=1) and superficial femoral artery (n=2). On the basis of acute and chronic TPA classification and different therapeutic principles, endovascular repair with ViabahnTM self-expanding covered stent was employed in 8 patients. Intraoperative angiographic findings, the size and number of the implanted stent, and the immediate angiographic results after stent implantation were recorded. All the patients were followed up to evaluate the improvement of the symptoms, the effectiveness of the repair of TPA cavity, and the occurrence of endoleak or restenosis. Results Successful implantation of ViabahnTM self-expanding covered stent was accomplished in all 8 patients, with a technical success rate of 100%. Angiography performed immediately after stent implantation showed that complete repair of TPA cavity was obtained in all patients, the distal segment of the parent artery was patent, and no endoleak was observed. The sizes of the stent used in the patients were 8×50 mm (n=2) and 9×50 mm (n=2) in common carotid artery, 6×50 mm (n=1) in vertebral artery, 11×100 mm (n=1) in subclavian artery, and 8×100 mm (n=2) in superficial femoral artery. The patients were followed up for 6-30 months (mean of 14.3 months), and the clinical symptoms disappeared in all patients. CT angiography indicated that there was no endoleak or restenosis. Conclusion Based on the different therapeutic principles, the use of ViabahnTM self-expanding covered stent in endovascular repair of peripheral TPA is technically simple and micro-invasive, and clinically feasible with reliable effect and safety. Therefore, this technique can be employed as a first-line therapy option for peripheral TPA.

Objective:Currently,traditional cervical cancer screening methods,such as high-risk human papillomavirus testing and liquid based cytology(LBC),still possess limitations.This study aims to identify new diagnostic biomarkers to achieve the goal of"precision screening"via exploring the clinical value of DNA methylation[ΔCtP:paired box gene 1(PAX1)and ΔCtJ:junctional adhesion molecule 3(JAM3)]detection in cervical exfoliated cells for the diagnosis of high-grade cervical lesions. Methods:A total of 136 patients who underwent gynecological examinations in the vaginal room of the Department of Gynecology at the Third Xiangya Hospital of Central South University from June 2021 to June 2022 were retrospectively studied.Among them,122 patients had non-high-grade cervical lesions,and 14 patients had high-grade cervical lesions.The variables included general information(age,body mass index,and menopause status),LBC,high-risk human papillomavirus,cervical tissue pathology,vaginal examination results,and the ΔCt values of JAM3 and PAX1 gene methylation.Logistic regression analysis was used to identify the factors affecting the diagnosis of high-grade cervical lesions,followed by correlation analysis and construction of a conditional inference tree model. Results:Logistic regression analysis showed that the methylation ΔCt values of PAX1 and JAM3 genes and LBC detection results were statistically significant between the high-grade cervical lesions group and the non-high-grade cervical lesions group(all P<0.05).Correlation analysis revealed a negative correlation between cervical pathological changes and ΔCtP(r=-0.36,P<0.001),ΔCtJ(r=-0.448,P<0.001),LBC(r=-0.305,P<0.001),or bacterial diversity(r=-0.183,P=0.037).The conditional inference tree showed that when ΔCtJ>10.13,all of patients had non-high-grade cervical lesions,while ΔCtP>6.22,the number of non-high-grade lesions accounted for 97.5%(117/120),and high-grade lesions accounted for only 2.5%(3/120).When ΔCtJ>8.61 and LBC were atypical squamous cell of undetermined significance or negative for intraepithelial lesions or malignancy(NILM),105(99.1%)patients were non-high-grade cervical lesions,only 1(0.9%)patient was high-grade lesion.When the results of LBC were high-grade lesions,only 9 patients'histopathological examination was the high-grade lesions and 3 non-high-grade lesions.When LBC indicated low-grade lesions,atypical squamous cell of undetermined significance,no intraepithelial lesions,and ΔCtP>6.22,117(97.5%)of patients'histopathological examination was the non-high-grade lesions. Conclusion:The JAM3/PAX1 gene methylation test can be used independently for the stratified diagnosis of high-grade/non-high-grade cervical lesions in women with high-risk human papillomavirus infection,independent of the cytological results of cervical excision.The JAM3/PAX1 gene methylation test can also be used in combination with LBC to make up for the shortcomings of low sensitivity of LBC.In addition,the application of methylation kit in large-scale cervical cancer screening in the future will be good to the detection of more patients with high-grade cervical lesions,and achieve early screening and early treatment for cervical lesions/cancer.

Currently, whole uterus and bilateral tubal resection and oophorectomy is the main treatment of cervical mullerian adenosarcoma. However, young patients generally wish to retain reproductive function. The clinical data of a patient with cervical mullerian adenosarcoma, who underwent fertility preservation surgery were collected. A 13-year-old girl with abnormal vaginal bleeding and a 1.0 cm flocculent echogenicity in the lower part of the uterine cavity to the cervical canal and a cervical mass of about 61 mm×37 mm was found in the pelvic MRI. After initial diagnosis of dysfunctional uterine bleeding in adolescence and cervical blood clot, the patient was treated with artificial cycle treatment, but her symptoms did not improve. Then she was transferred to the Third Xiangya Hospital of Central South University for uninjured virgin membrane hysteroscopy and cervical mass electrotomy, but a few pedicles remained after the operation, and the pathology suggested a cervical mullerian adenosarcoma. Because the patient was young and had not yet given birth, she was treated with primary IAP regimen of chemotherapy and subcutaneously injected with gonadotropin-releasing hormone analogue (GNRH-A) once every 28 days (6 times in total) to protect the ovarian function. After the chemotherapy, she was treated with uninjured virgin membrane hysteroscopy and pedicle electrotomy of cervical mullerian adenosarcoma. After the operation, she received chemotherapy with IAP regimen for 5 times. After discharge, she was treated with megestrol 200 mg per day for 3 years. During 5 years of regular follow-up, no abnormality was seen. Cervical mullerian adenosarcoma in non-sexual women is easily misdiagnosed as ovulation dysfunction abnormal uterine bleeding. The necessity of hysteroscopy should be emphasized, and for patients with low-grade early-stage lesions who wish to retain fertility, local resection could be chosen, but attention is paid to lifelong follow-up to exclude long-term recurrence.

This study analyzed the inherent relation between arterial blood mass flow and muscle atrophy of residual limb to provide some necessary information and theoretical support for the clinical rehabilitation of lower limb amputees. Three-dimensional arterial model reconstruction was performed on both intact side and residual limb of a unilateral transfemoral amputee who is the subject. Then hemodynamic calculation was carried out to comparatively analyze the mass flow state at each arterial outlet of both lower extremities. The muscle atrophy ratio of residual limb was calculated by measuring the cross-sectional area of bilateral muscles. Based on the blood supply relationship, the correlation between arterial blood flow reduction ratio and muscle atrophy ratio was discussed. The results showed that the mass flow of superficial femoral arteries and lateral circumflex femoral arteries severely reduced. Meanwhile rectus femoris, vastus lateralis and vastus medialis which were fed by these arteries showed great atrophy too. On the contrary, the mass flow of deep femoral arteries and medial femoral circumflex arteries slightly reduced. Meanwhile gracilis, adductor longus, long head of biceps which were fed by these arteries showed mild atrophy too. These results indicated that there might be a positive and promotion correlation between the muscle atrophy ratio and the blood mass flow reduction ratio of residual limb during rehabilitation.
