Objective To investigate the clinical value of thinprep cytology test(TCT) combined with colposcopy in diagnosis of cervical lesion. Methods Retrospective analysis was conducted in 174 females with abnormal cervical smear. All the patients underwent colposcopy to screen the cervical lesions. According to the pathological results,the clinical value of TCT and colposcopy was analyzed and compared. Results In the 174 cases with abnormal cervical smear,the positive rate of atypical squamous cells(ASC) was 27. 0% (47/174). There were 92 low grade squamous intraepithelial lesion (LSIL) (52. 9%) ,33 high grade squamous intraepithelial lesion (HSIL) (19. 0%) and 2 squamous cell cancinoma (SCC) (1. 1%) . According to the diagnosis by biopsy and pathology,the positive rate of benign cervical cell(BCC) was 16. 1% (28/174) .cervical intraepithelial neoplnsia (CIN) I 42. 0% (73/174), CIN II 18.4% (32/174), CIN ffl 21. 8% (38/174) and SCC 1. 7% (3/174) . The coincidence rate of TCT and pathology was 83. 9% (146/174). Conclusions TCT and colposcopy are a practical approach for detecting cervical lesion. TCT combined with colposcopy is the optimal screening approach for cervical lesion, which can enhance the sensitivity and specificity of the diagnosis of cervical lesions.

Objective:Continuous acquisition of swallowing images of head and neck cancer patients by using MRI technique was performed to observe and measure the movement regularity and maximum displacement of the soft palate, tongue and larynx.Methods:From July 2018 to October 2018, 20 patients with primary head and neck cancer were chosen randomly, 17 male and 3 female. The median age was 58.5 years (28 to 78 years). Among the 20 patients, 7 patients were diagnosed with nasopharyngeal carcinoma, 3 patients with oral cancer, 5 patients with oropharyngeal cancer, 3 patients with hypopharyngeal cancer, and 2 patients with nasal and paranasal sinuses cancer. Two patients were classified as stage Ⅰ-Ⅱ, 8 patients as stage Ⅲ and 10 patients as stage Ⅳ according to the eighth edition of AJCC.Results:The displacement of the upward movement of the soft palate during swallowing was (1.06±0.31) cm and followed the pattern normal distribution. The displacement of backward movement of the soft palate was (0.83±0.24) cm, which also almost normally distributed. The displacement of backward tongue movement was (0.77±0.22) cm and followed the normal distribution pattern. The displacement of upward tongue movement was 0 in patients with tongue depressor for image acquisition. The mediandisplacement of upward tongue movement in patients without tongue depressor was 1.23 cm (0.59 to 1.41 cm). The displacement of upward laryngeal movement was (1.14±0.22) cm and followed the normal distribution pattern, and the median displacement of forward laryngeal movement was 0.4 cm (0.27 to 0.90 cm).Conclusions:Swallowing movement may occur in head and neck cancer patients during radiotherapy. It can also cause the movement of gross tumor volume (GTV) and surrounding normal tissues. Therefore, extensive attention should be paid to the individual distance between GTV and planning gross tumor volume (PGTV) when making radiotherapy plans, aiming to ensure the prescription dose of cancer.

ObjectiveTo analyze the changing trend of cerebrovascular disease burden in Minhang District of Shanghai from 1996 to 2021， and to provide scientific evidence for government to formulate targeted cerebrovascular disease prevention and control strategies. MethodsMortality， years of life lost（YLL）， years of lived with disability（YLD） and disability⁃adjusted life years（DALY） were used to evaluate the burden of cerebrovascular diseases in Minhang District. Joinpoint linear regression was used to analyze the trend of disease burden. ResultsFrom 1996 to 2021， the YLL rate of cerebrovascular diseases in Minhang District showed a downward trend （whole population： APC=-1.69%， t=-6.9， P<0.05）， The YLD rate of cerebrovascular diseases showed a slow upward trend （whole population： APC=1.17%， t=3.5， P<0.05）， The DALY rate of cerebrovascular diseases showed a downward trend， and fluctuated since 2003 （whole population： APC= -1.43%， t=-5.6， P<0.05）. The YLL rate of cerebrovascular diseases in men was higher than that in women， and the YLD rate of cerebrovascular diseases in women was higher than that in men. After 2014， the DALY of cerebrovascular diseases in men was higher than that in women. With the increase of age， the burden of cerebrovascular diseases increased， and the burden of disease increased significantly in the age group above 70. ConclusionThe burden of cerebrovascular diseases in Minhang District is at a high level， and there are differences in age， gender and other aspects. Measures such as screening， intervention and rehabilitation need to be improved to reduce disability and premature death caused by cerebrovascular diseases and to reduce the burden of cerebrovascular diseases on individuals， families and society.
