ABSTRACT
Cervical cancer is still a serious threat to the health of women in China. The current strategy is a three-level prevention strategy, among which the diversion of screening and screening abnormalities in the secondary prevention is an important link in preventing cervical cancer. For more than 20 years, China has implemented diversified screening methods such as cytological examination, high-risk human papillomavirus (HPV) testing, and naked eye screening. With the discovery that high-risk HPV infection is closely related to the occurrence of cervical cancer, the screening method for cervical cancer has shifted from cytological examination to HPV testing as the preferred screening method. This article introduces the advantages and disadvantages of high-risk HPV testing and cytological examination as screening methods, and proposes the issues that need to be paid attention to in screening; The principle of diverting screening abnormalities was proposed, and it was proposed that in the process of diverting, individualized and refined management principles should be implemented for screening abnormality projects based on the patient′s age and fertility requirements.
ABSTRACT
Objective To investigate the status and its influencing factors of spiritual health of patients with gastrointestinal malignant tumors. Methods Totally 147 advanced cancer patients from three tertiary hospitals in Tianjin (Tianjin Hospital of ITCWM Nankai Hospital, Tianjin Medical University Cancer Institute and Therapy, The Second Hospital of Tianjin Medical University) were enrolled through convenience sampling methods. The status of spiritual health and quality of life were analyzed by the Functional Assessment of Chronic Illness Therapy-Spiritual Well Being Scale (FACIT-Sp-12) and the World Health Organization′s Quality of Life Questionnaire-Brief Version Scale(WHOQOL-BREF). Results The overall scores of the FACIT-Sp-12 were (25.64 ± 2.84) points, at a lower-middle level,the overall scores of the WHOQOL-BREF were (11.24 ± 2.85) points,at a lower level. Multiple linear regression analysis showed that the age,religious belief and educational level were influencing factors of spiritual health( P<0.05). Conclusions The level of spiritual health of advanced cancer patients is at lower-middle level. With different age,religious belief, educational level the status of spiritual health is different. Nurses should carry out targeted nursing intervention according to individual conditions of patients with gastrointestinal malignant tumors to improve their quality of life.
ABSTRACT
Objective To investigate the acceptance of HPV self-sampling mode in cervical cancer screening population and explore its feasibility. Methods From March 5 to 15, 2018, researchers investigated women who participated in cervical cancer screening organized by Beijing Shunyi Women＇s and Children＇s Hospital in the form of questionnaires. Questionnaires were conducted on their acceptance status and the factors that affect the self-sampling experience. The specific contents of the questionnaires were as follows: (1) the experience of using self-sampling included operability, comfortable, sample time-consuming, bleeding or not after sampling; (2) psychological changes after self-sampling, including the willingness to accept self-sampling again, the worrying problems during self-sampling process. According to whether or not have operating video guidance, the self-sampling experience and psychological changes after self-sampling were compared. Results (1) There were 1 375 women participated in the questionnaire survey, and 86.55% (1 190/1 375) of them thought the self-sampling was convenient, 78.40% (1 078/1 375) thought it was not uncomfortable, 88.58% (1 218/1 375) thought the sampling time was fast (less than 5 minutes), 94.04% (1 293/1 375) self-sampling without bleeding; and 83.27% (1 145/1 375) were willing to self-sampling for cervical cancer screening again, 85.82% (1 180/1 375) were afraid of inaccurate sampling. (2) Among the 1 375 women, 1 202 were in the video guidance group and 173 were in the non-guidance group. The self-sampling experience of women in video guidance group was better than those of non-guidance group in operability, comfortable, sampling time-consuming and bleeding after sampling. The proportion of women who willing to self-sampling again was higher than that of non-guidance group (86.69% vs 59.54%, respectively). The proportion of women who worried operating incorrectly was lower than that of non-guidance group (11.23% vs 32.37%, respectively). The differences were significant (all P<0.05). Conclusions Self-sampling for HPV testing in cervical cancer screening is easy to operate and has little discomfort complaint. It is feasible in cervical cancer screening. Operational video guidance during the screening process could effectively improve the women＇s experience and willingness to self-sampling again in the future.
ABSTRACT
Objective To study the clinical management way for HPV+/papanicolaou (Pap)-during cervical cancer screening.Methods To analyze retrospectively the data from the patients who had loop electrical excision procedure (LEEP) for biopsy confirmed cervical intraepithelial neoplasia (CIN)Ⅱ in Peking University People's Hospital from Jan.2010 to Dec.2014.Results (1) For biopsy confirmed CINⅡ,HPV positive rate was 98.5％ (135/137),Pap test positive [≥atypical squamous cell of undetermined significance (ASCUS)] rate was 69.3％ (95/137),there was significant difference between them (x5=43.32,P＜0.01).(2) For the 42 patients with HPV+/Pap-,whose cytology slides were reviewed again.Among them,the interpretations of there were 16 cases confirmed as the same before,while 26 cases were changed to abnormal (≥ASCUS).Cytology be misdiagnosed was 19.0％ (26/137) at the first review.Among the 26 cases,13 (50.0％) cases were missed for the little amount of abnormal cells,8 (30.8％) cases for mild atypical morphology changed;the other 5 (19.2％) cases missed for stain problems.(3) For the cervical LEEP samples,37 cases of the pathology diagnosis were upgrade to CIN Ⅲ+,among them,2 cases of microinvasive cervical carcinoma,1 case of invasive cancer,34 cases of CIN Ⅲ;37 cases were CINⅠ or no lesion found;63 cases were still CIN Ⅱ.Four to six months later after LEEP,the cytology abnormal rate was 11.7％ (16/137),and the HR-HPV positive rate was 34.3％ (47/137).Conclusions Compared with cytology alone,cytology combined with HPV testing increase the sensitivity of cervical high grade lesion.For the cases of HPV+/Pap-cases,the cytology slides should be reviewed.The quality control of cervical exfoliate sample collection and interpretation should be strengthened.LEEP procedure is not only a treatment method,but also it could provide samples to confirm the diagnosis.

ABSTRACT
Objective:About half of Community Health Services ( CHS) in China are not government-owned, forming a multi-ownership situation of CHS .This study aims to examine the effect of “multi-ownership policy” on the development of CHS and put forward suggestions for improving the governance of CHS .Methods:We applied maxi-mum variation sampling to select health workers of different CHS specialties and administrators from local health bu -reaus in District T of Shaanxi province and District X of Shandong province .Inductive thematic analysis was utilized to interpret the development and ramification of multi-ownership policy , and then to formulate substantive theory .Re-sults:The adoption of multi-ownership in two districts was an adaptive strategy based on the limited public finance , institutional restriction of government , and diversity of health resources .This policy promoted the establishment of CHS network , and meanwhile the government's leadership of CHS development was transferred to multiple owners of CHS, which caused the lack of CHS autonomy , fragmented regulation power and deviated development of CHS .Con-clusions:The key problem of multi-ownership situation in CHS development is the problematic partition of governance power.In order to redeem the leadership of CHS development to the local government , it is necessary to strengthen service regulation while to decentralize the facility management power to CHS , to adjust service price ,and to deepen medical insurance coverage of CHS to enhance autonomy of CHS .
ABSTRACT
Objective To evaluate the application value of high-risk human papillomavirus (HR-HPV)DNA de-tection and ThinPrep liquid-based cytology testing(TCT)in cervical disease screening.Methods Cervical specimens of women with cervical lesions in a hospital between October 2012 and December 2013 were taken and performed hu-man papillomavirus DNA genotyping (HPV DNA)and ThinPrep liquid-based cytology testing(TCT).Positive pa-tients were performed colposcopy pathological detection.HPV DNA positive rates among different TCT groups, and different cervical lesion groups were compared,the sensitivity and specificity of TCT and HPV DNA detection, as well as differences between separate and joint detection were also compared.Results The positive rate of HPV DNA was 28.07% (1 045/3 723),most were HR-HPV (21 .57%,n=803),the major HR-HPV genotypes were HPV 16,58,52,and 18 type.HR-HPV positive rates were statistically different among different age groups(χ2 =31 .74,P tection was as a gold standard ,the sensitivity of HR-HPV DNA and TCT was 90.44%(265/293)and 85.32%(250/293)respectively,the sensitivity of joint HR-HPV DNA detection and TCT was 95.90%.In positive patho-logical group,the detection rate of TCT and HR-HPV DNA was 85.32% and 90.44%,respectively,joint detec-tion rate was 95.90%,the difference among three groups was significant (χ2 =18.185,P <0.001).Joint detection rate was higher than separate detection rate of TCT or HPV DNA.Conclusion HPV DNA detection is a useful supplement for cervical cancer screening,HPV DNA detection combined with TCT can reduce the misdiagnosis rate.

ABSTRACT
Objective To investigate the significance of genomic amplification of the telomerase RNA component (TERC) gene to serve as a genetic biomarker in the screening of cervicallesions.Methods A total of 715 cases were recruited,with liquid-based cytology diagnosis as normal (n=347),atypical squamous cells of undetermined significance (ASCUS,n=180),atypical squamous cells cannot exclude a high-grade lesion (ASC-H,n=13),low-grade squamous intraepithelial lesions (LSIL,n=115),high-grade squamous intraepithelial lesions(HSIL,n=59)and atypical glandular cells(AGC,n=1).The remaining cervical cells in the cytological preserving fluid were analyzed using a two-color fluorescence in situ hybridization (FISH) probe targeted to chromosome 3q26 containing TERC gene.The TERC gene findings were compared to the cytological and histological detected results,as well as high-risk human papillomavirus (HPV) detected results.Results Genomic amplification of TERC gene was found in 5.8% of normal specimens,22.2% of ASCUS.30.8% of ASC-H,27.8% of LSIL,86.4% of HSIL and 1/1 of AGC.The positive rate was significantly lower in normal,ASCUS,ASC-H and ISIL.compared with HSIL(all P<0.01).Significantly more cells with genomic amplification of TERC gene were found in cervical intraepithelial lesion(CIN) Ⅱ-Ⅲ than CIN Ⅰ (77.8% vs.9.3%),as well as invasive cervical cancer (96.7% vs.9.3%).both P < 0.01.The rate of TERC gene amplification was higher in HPV positive patients (33.5%) than in HPV negative patients(5.2%,P<0.01).The sensitivity of TERC gene amplification was significantly higher than that of cytological screening (81.88% vs.36.96%,P<0.01) in the differentiation of CIN Ⅱ or higher and CIN Ⅰ or lower diseases,its specificity Was hisher than high-risk HPV test (93.32% vs.33.93%,P<0.01) and positive prediction value (81.29%) was similar with cytological method (86.44%,P>0.05);but its negative prediction value (93.56%) was lower than HPV test (97.06%,P<0.05).Conclusions The positive rates of TERC gene amplification increased as cervical diseases worsened.TERC gene amplification is related to HPV infection.The gain of chromosome 3q26 in cytological specimens is an effective molecular genetic biomarker in screening of CIN Ⅱ or higher and invasive cervical cancer.
ABSTRACT
Objective To investigate the genomic amplification of the human telomerase RNA component (hTERC) gene in cervical cytology and evaluate its role in screening of cervical lesions. Methods A total of 301 cases were recruited, with liquid-based cytology diaghoses as normal (n=203), atypical squamous cells (ASC, n=66), low-grade squamous intraepithelial lesions ( LSIL,n=18), and high-grade squamous intraepithelial lesions ( HSIL, n=14). Following cytological examination, the slides were analyzed using a two-color fluorescence in aitu hybridization ( FISH ) probe targeted to chromosome 3q26 containing hTERC. The hTERC findings were compared to the cytologic and histologie results, as well as high-risk human papilloma viruses (HPV) results. Results Genomie amplification of hTERC was found in 3.0% (6/203)of normal specimens, 21.2% (14/66) of ASC, 44.4% (8/18) of LSIL and 92.9% (13/14) of HSIL, with a significant difference in each pair wise (all P<0.05). Significantly more cells with 3q26 gain were found in cervical intraepithelial lesion (CIN) Ⅱ than in CIN Ⅰ(75.0% vs. 20.0% ), as well as in CIN Ⅲ (86.7% vs. 20.0% ) and squamous cervical cancer (SCC) than in CIN Ⅰ (100.0% vs. 20.0%) ( all P<0.01). The sensitivity of hTERC amplification was significantly higher than cytological screening (82.6% vs. 17.4%, P<0.01), and its specificity was higher than high-risk HPV test (67.8%-73.5% vs. 25.6%-27.7%, P<0.01) in the diagnosis of HSIL (CIN Ⅱ - Ⅲ). The abnormal hTERC signal type mostly was 2:3 in CIN Ⅰ (84.9% ) ; whereas in CIN Ⅱ-Ⅲ, 2: 3, 2:4 and 4:4 accounted for 44.6%, 24.8% and 17.8%, respectively. Conclusion Testing the gain of chromosome 3q26 in cytological specimens using specific probe for hTERC is powerful in screening of HSIL, and the amplification patterns of 2:4 and 4:4 may serve as potential prognosis markers.
