s are maintained over time.The 12-year-old patient was admitted to the hospital on September 19, 2019 for "vaginal bleeding for 2 + months and pelvic mass to be diagnosed". The patient and her family explicitly denied any previous history of diethylstilbestrol exposure. Navitoclax inhibitor After admission, relevant examinations were conducted and hysteroscopic exploration was performed under general anesthesia. During the procedure, cervical neoplasms were extracted and pathology results indicated cervical cancer. Then, extensive transabdominal hysterectomy+bilateral salpingectomy+bilateral ovarian transposition+pelvic lymph node dissection+para-aortic lymph node sampling were performed. Postoperative pathology analysis of the removed tissue showed that clear cell carcinoma of cervix (CCAC) had infiltrated into 1/3 of the cervical stroma and there was downward involvement of the vaginal wall; the cancer metastasized to the left obturator lymph node and the left internal and external iliac lymph nodes. Immunohistochemical staining of the removed tissue showed the following results cytokeratin 7 (+), cytokeratin 20 (-), Napsin-A (+), cell adhesion molecule CD15 (+), heatocyte nuclear factor-1 β (+), Sal-like protein 4 (-), tumor suppressor gene P16 protein (+), estrogen receptor (+), progesterone receptor (-), tumor suppressor gene P53 protein (focal positive), tumor suppressor gene WT-1 protein (-) and Ki67 antigen (about 40% positive). The patient was diagnosed with CCAC stage ⅢC1p. Four cycles of postoperative systemic chemotherapy (fluorouracil+cisplatin) and 25 times of three-dimensional afterloading radiotherapy were performed. The patient did follow-up visits and did not show obvious signs of recurrence. The clinical manifestations of this disease are basically the same as those of cervical squamous cell carcinoma, and if the patient is younger, it can be easily misdiagnosed as dysfunctional uterine bleeding, indicating the need for differential diagnosis.The patient, a 25-year-old woman, was seen at our hospital 6 years ago, complaining of weakness and stiffness in the left side of the body and left limbs for 1 + years. Physical examination revealed atrophy of the upper and lower limbs on the left side. Neurological examination showed increased muscle tone in the left-side body and limbs, bradykinesia, decreased muscle strength in the left-side body and limbs, and positive Hoffman's sign in the left limbs. Laboratory tests, including alpha fetoprotein (AFP), β-human chorionic gonadotropin (HCG) and cerebrospinal fluid examination, did not reveal any abnormal results. Head MRI showed right cerebral hemiatrophy. Head and neck CT angiography did not show obvious abnormality. According to the medical history and examination results, diagnosis of hemiparkinsonism-hemiatrophy syndrome was made. Through close follow-up for 6 years, we noticed that the parkinsonism remained unilateral and stable, and the contralateral cerebral hemiatrophy did not show obvious progress. However, brain perfusion MRI showed hypoperfusion of the right basal ganglia. The discovery of hypoperfusion in the basal ganglia may help explore the etiology of hemiparkinsonism-hemiatrophy syndrome.A 42-year-old male was admitted for paroxysmal syncope for 10 + months, chest tightness for 20 + days and chest pain for 10 + days. The patient was diagnosed with hypertrophic cardiomyopathy. The patient did not have a history of hypertension or diabetes. Coronary angiography and left ventricular cardiac catheterization were done in order to examine the coronary artery and the pressure gradient of the left ventricular outflow tract. The cardiac catheterization was performed via a right radial artery approach and a total of 200 mL of 370 mg I/mL iopromide was injected. The patient developed contrast-induced encephalopathy following the cardiac catheterization procedure, displaying severe headache, cortical blindness and neuropsychiatric symptom as the main clinical manifestations. The patient was then given symptomatic and supportive treatment, including decreasing intracranial pressure, analgesics and sedatives, and the patient recovered.

To investigate the value of MRI after ultrasonic gel vagina filling in the staging of early-stage cervical cancer.

A total of 158 patients with cervical cancer who underwent MRI examination after their cervical cancer diagnosis was confirmed by cervical biopsy were prospectively enrolled. Routine MRI examination was performed first, followed by another MRI examination after vaginal filling with ultrasound gel. Two physicians used a double-blind method to determine the staging of cervical cancer based on the MRI images before and after vaginal filling of ultrasound gel. Results of the postoperative pathology analysis were used as the golden standard. The positive predictive value and negative predictive value for stage Ⅱa cases of the two examinations of the same patient were compared, and the sensitivity, specificity and accuracy in identifying stage Ⅱa cervical cancer were compared.

Two physicians used the double blind method to determine the staging of cervical cancer based on conventional MRI images,cervical cancer.

MRI examination after ultrasound gel vaginal filling has better diagnostic value for identifying stage Ⅱa cervical cancer. The method is simple and easy to do, and can be used in routine MRI examination of cervical cancer.

To explore the expression of human papilloma virus (HPV) L1 protein and programmed cell death ligand-1 (PD-L1) protein in cervical precancerous lesions and cervical cancer, to analyze the correlation between HPV L1 and PD-L1 expression tests combined with colposcopy and the occurrence and development of of cervical lesions, and to determine the significance of the combined examination for auxiliary differential diagnosis.

260 patients with high-risk HPV (HR-HPV) infection who were treated at West China Second University Hospital, Sichuan University from January, 2018 to January, 2020 were included in the study. 260 cervical cytology specimens were collected, of which 218 cervical histology specimens were collected, of which 202 cases underwent colposcopy. Among the 260 cervical cytology specimens, 40 were of cervical inflammatory cells, 40 were of low-grade squamous intraepithilia lesions (LSIL) with mild atypical hyperplasia, 80 were of high-grade squamous intraepithilia lesions (HSIL) with moderate and severe atypical hyperplasia, and 100 were of cervical carcinoma cells (CCC).
