Study on the status of radiological protection in Baoji City / 中国辐射卫生

Objective To investigate the status of radiological protection in Baoji City. Methods Using the questionnaire survey method, the survey forms were sent to the radiology clinics and other relevant units in the counties and districts of the city to investigate the basic situation of radiology and treatment of medical and health institutions, basic information of radiology and treatment equipment, personal information of radiation workers, and health monitoring of radiation workers. Results There is 1.13 X-ray diagnostic equipment per 10, 000 people, 0.015 radiotherapy equipment per 10, 000 people in Baoji City, and One million people own 11.4 CTs. There are 1, 102 radiation workers in Baoji City, and 2.92 per 10, 000 people. The occupational health check rate of medical radiation personnel was 87.7% within 2 years, the personal dose monitoring rate was 90.4%, the radiation worker training rate was 73.6% within 2 years, about the holding rate of "Radiation Staff Certificate" in Baoji City was 73.0%, and the occupational health file rate was 89.2%. The evaluation indexes of various health monitoring were lower, especially in township hospitals (35.7%～50.8%). Conclusion On the whole, the number of radiological diagnosis and treatment equipment is small, and Class A large equipment is almost blank. The city is stronger than the county in health monitoring. The status of health monitoring is very different from urban to rural areas.

Evaluation of four approaches in screening of cervical lesions / 中华全科医师杂志

Exfoliative cell samples were collected from 545 patients in outpatient clinic of Kelamayi Centre Hospital from Sep 2009 to Dec 2010. Liquid-based cytology test ( LCT ) and high-risk human papillomavirus (HR-HPV) test were performed in exfoliative cells; and colposcopic biopsy was undertaken in all patients.With the pathological results as gold standard the diagnostic values of HR-HPV test,LCT test,HPV-LCT serial test and HPV-LCT parallel test were evaluated for cervical cancer screening.The sensitivity of HPV-LCT parallel test was 99.17％ with a Youden's index of 0.81.Our results indicate that HPV-LCT parallel test can improve significantly the detection rate of cervical cancer screening.

Evaluation of clinical application of approaches in cervical cancer screening / 肿瘤研究与临床

Objective To evaluate the function of Hybrid capture 2 (HC2) human papillomavirus (HPV) test,liquid-based cytology test (LCT),HPV serial test,LCT serial test and HPV-LCT parallel test for cervical high-grade lesions screening and to guide in selecting the scheme of cervical cancer screening.Methods HPV test,LCT,and colpescopic biopsy were performed in 545 women treated in Centrale Hospital of Klamayi from Sep.2009 and Dec.2011.The pathology results were the final diagnosis to evaluate the value of each approach for screening cervical cancer.Results Of 545 patients, 10 had cervical cancer.41 had cervical intraepithelial neoplasia CIN3,69 had CIN2,and 120 had CIN 1.Positive rate of high risk HPV was 64.22 ％.The sensitivity,specificity,accuracy,positive pre-value,and negative pre-value of HPV test for detecting high-grade cervical lesions were 95.83 ％,84.71％,88.48 ％,30.68 ％,99.12 ％,respectively.The values of LCT were 84.20 ％,89.53 ％,85.53 ％,36.69 ％,91.76 ％,respectively.The values of LCT serial test were 81.03 ％,95.96 ％,78.33 ％,40.69 ％,92.92 ％,respectively.The values of HPV serial test were 81.03 ％,95.26 ％,78.33 ％,42.15 ％,99.52 ％,respectively.The values of HPV-LCT parallel test were 99.20 ％,81.53 ％,90.03 ％,32.09 ％,99.33 ％,respectively.Conclusion HPV-LCT parallel test can significantly improve the detection rate of cervical cancer screening.
