Objective To explore the correlation of high-risk type HPV infection with mycoplasma,chlamydia infection in sterile female patients.Methods The cervical specimens from 524 sterile female patients in northwest area were performed the laboratory detection of high-risk type HPV,mycoplasma and chlamydia.The correlation among these 3 kinds of pathogen was analyzed.Results In 524 sterile female patients,the sequence of the infection rate of 3 kinds of pathogen from high to low was mycoplasma,high-risk type HPV and chlamydia.The positive rate of high-risk type HPV in the patients with simple mycoplasma positive,simple chlamydia positive and double positive of mycoplasma and chlamydia was significantly higher than that in the patients with myco-plasma and chlamydia negative,the difference had statistical significance(P <0.05).Conclusion Certain correlation exists between the high-risk type HPV infection with mycoplasma and the chlamydia infection in sterile female patients.So it is suggested that in the pathogenic microbiological detection,such patients in clinic need to simultaneously perform the high-risk type HPV detection in addition to completing the laboratory detection of mycoplasma and chlamydia.

Objective:Total 621 cases of medical disputes occurred during 2000 to 2013 were analyzed retro-spectively, to investigate the dispute factors and analysis of improvement, to promote doctor-patient relationship. Methods:621cases of medical disputes from 2000 to 2013, on a case by case attributes are classified, analyzed two year interval comparison, find the dispute factors in evolution.Results:Through the analysis of 621 cases of disputes over property, complications of the disease cause dispute case first, economic reasons, the second medical defect.Conclusions:Analysis of the two year interval comparison shows:how to strengthen the hospital scientific management, innovative service mode, the medical system implemented is the important link of reducing medical disputes.

This article introduces ethical problems emerging in the imaging trials in clinical practice,and stresses the importance of protecting the privacy of volunteers and patients,and their legal rights of informed consent.This article also stresses the importance of the respect for the basic human right of volunteers and patients,and puts forward some countermeasures to promote the efficiency and reasonable supervision system in the clinical trials.Last but not least,it also emphasizes the significance of a personalized-style of care for volunteers and patients.

Objective To investigate reflectance confocal microscopy (RCM) characteristics of childhood hypopigmented lichen striatus.Methods RCM was performed to image skin lesions and perilesional normal skin in 11 children with hypopigmented lichen striatus.Then,confocal microscopic findings of the skin lesions were compared with pathological findings.Results Histopathological examination of the skin lesions showed mild intercellular and intracellular edema,thickening of prickle cell layer to different extent,local liquefaction degeneration of basal cells,and perivascular infiltration of plenty of lymphocytes and a few melanophages in the superficial dermis.RCM horizontal images showed multifocal liquefaction degeneration of basal cells,which caused indistinct dermo-epidermal junction,incomplete or unclear dermal papillary rings,infiltration of many highly refractive melanophages and slightly to moderately refractive inflammatory cells in papillary and superficial dermis.Conclusion RCM characteristics can serve as strong evidences for the diagnosis and differential diagnosis of childhood hypopigmented lichen striatus.

Objective To further strengthen the management of radiological health technical service institutions, standardize their technical service behaviors, and explore the supervision countermeasures for radiological health and technical service institutions. Methods The radiological health technical service institutions status questionnaires s were designed to survey the basic situation, professionals and technical personnel, the equipment configuration, testing items and workload of service institutions. Results By the end of 2019, there were 23 radiological health technical service institutions in Hebei province, including 8 disease control and occupational prevention institutions (accounting for 34.8%) and 15 third-party institutions (accounting for 65.2%); The distribution of regional agencies were unbalanced; There were 223 professional and technical personnel, of which 29.6% were senior technical professionals, 29.6% were intermediate technical professionals and 40.8% were other professionals.58.8% had a bachelor's degree or above, and 41.2% had a college degree or below; The majors of professionals were relatively scattered, with only 6.44% of radiological health, 5.15% of physics-related majors, and 51.07% of medical-related majors. Other majors involve chemical pharmacy, environmental engineering, public relations planning, food, English, accounting and other majors.The professional technical responsible person had no part-time job;. The institution were totally equipped with 308 sets of radiation protection detectors and 172 sets of phantoms, basically in line with the configuration requirements; All quality control system documents such as quality management manuals, procedural documents, operating procedures, and work instructions have been established; All test items applied by laboratory measurement certification have passed;Conclusion The CDC institutions were gradually shrinking, the private institutions were gradually increasing and the nature of the institutions was gradually diversified.The allocation of regional resources was unbalanced.It is suggestedto strengthen the training on the theoretical basis and professional skills of professionals in testing and evaluation. Increasing on-site practical training is a more important and effective way.It is recommended to strengthen the training of basic-level health administrative departments and supervisory agencies and improvethe sense of responsibility of supervisors.

Objective: To standardize the occupational health management of radiation workers and raise the management level and technical content for the supervision of occupational health of radiation workers. Methods: The information system for radiation worker passbook was established and applied in Hebei province for practice. Results: Until December 2018, 4 339 passbooks have been issued to radiation workers from 140 medical institutions. Through the establishment and operation of the radiation worker passbook information system, the basic information and distribution characteristics of the provincial registered medical institutions and their radiation workers in Hebei province were obtained. The efficiency of the examination and approval and issuance of radiation worker certificates by the health administrative departments was improved by reducing the intermediate procedure. Conclusions Data are obtained and provided for the discussion of electronic card management of occupational health of radiation workers, real-time query of information such as medical institutions of radiation workers, education and training, individual dose monitoring, occupational health examinations, and diagnosis and identification of occupational radiological diseases. Reference basis is provided for health administrative departments to carry out radiation worker supervision.
