HIV testing is the first step in HIV prevention and control, the rate of HIV infection is high and the rate of HIV testing is low among men who have sex with men (MSM) in China. HIV self-testing provides MSM with a new choice and plays a vital role in expanding the coverage of HIV testing in this population. This paper reviews HIV self-testing and associated factors among MSM in China and provides a reference for promoting HIV self-testing in this population.

Objective: To understand HIV self-testing and related factors in men who have sex with men (MSM) in Shijiazhuang. Methods: From August to September 2020, convenient sampling was used to recruit MSM in Shijiazhuang. Online questionnaires were used to collect information about their demographic characteristics, sexual behaviors and HIV self-testing. logistic regression model was used to analyze the related factors associated with HIV self-testing. Results: In the 304 MSM respondents, 52.3% (159/304) had HIV self-testing in the past 6 months, and 95.0% (151/159) used fingertip blood HIV detection reagent. Self-purchase was the main way to obtain HIV testing reagents (45.9%, 73/159), followed by supply from MSM social organization (44.7%, 71/159). The reasons for having HIV self-testing were non-specific testing time (67.9%, 108/159) and privacy protection (62.9%,100/159), the reasons for having no HIV self-testing included inability of using (32.4%, 47/145), being unaware of HIV self-testing reagent (24.1%, 35/145), and worry about inaccurate self-testing results (19.3%, 28/145). Multivariate logistic regression analysis showed that being 18-29 years old (aOR=2.68, 95%CI: 1.20-5.94), obtaining free HIV self-testing kits in recent 6 months (aOR=8.61, 95%CI: 4.09-18.11) and making friends through Internet and social software (aOR=2.68, 95%CI: 1.48-4.88) were positive factors for having HIV self-testing. Conclusion: HIV self-testing is a more flexible and convenient way to detect HIV in MSM, and the promotion of HIV self-testing in MSM should be strengthened to further increase the HIV detection rate in this population.

Objective: To analyze the trajectories of HIV testing self-efficacy among men who have sex with men (MSM) based on latent class growth model. Methods: From August 2019 to May 2021, 404 MSM were recruited in Shandong Province and subjected to a 1-year follow-up study with individual intervention (pushing intervention pictures and videos in WeChat and follow-up questionnaires) and community intervention (forwarding to friends and sharing and discussing HIV testing-related information in WeChat groups). The level of HIV testing self-efficacy among MSM was measured. The long-term trend of HIV testing self-efficacy was analyzed using the latent class growth model (LCGM), and the influencing factors of the trend were analyzed. Results: A total of 404 MSM were (28.25±8.95) years old, with the oldest being 58 and the youngest being 18. The scores of HIV testing self-efficacy M(Q₁, Q₃) at baseline and 4 follow-ups were 18.00 (17.00, 21.00), 19.00 (18.00, 22.00), 19.00 (18.00, 22.00), 19.00 (18.00, 22.00) and 19.00 (18.00, 22.00). The results of the freely estimated two-category LCGM model showed that the trend of HIV testing self-efficacy among MSM could be divided into two classes, "intervention response group" [255(63.1%)] and "intervention non-response group" [149(36.9%)]. The former had a higher level of HIV testing self-efficacy which tended to increase at first and then decrease over time, while the latter had a lower and more stable level. The results of the multifactorial logistic regression analysis showed that the OR values of MSM in business or service and jobless or unemployed were 0.261 (95%CI: 0.108-0.633) and 0.186 (95%CI: 0.057-0.610), respectively, using the students as the reference group. Conclusion: There is a group heterogeneity in the trend of HIV testing self-efficacy in the intervention conditions among MSM, and occupation may be an influencing factor.

Hereditary predisposition to breast and ovarian cancer and responsible for autosomal-dominant transmission, most commonly due to germline mutations in BRCA1 and BRCA2 has been recognized for many years. Hereditary breast cancer is characterized by early age at onset, bilaterality, vertical transmission through both maternal and paternal lines, and familial association with tumors of other organs, particularly the ovary and prostate gland. Most of the BRCA1 and BRCA2 mutations are predicted to produce a truncated protein product, supporting the hypothesis that they are tumor suppressor genes. Progress in determining the function of BRCA1 and BRCA2 suggests that they are involved in two fundamental cellular processes, DNA damage repair and transcriptional regulation. Several series have examined the prevalence of germline BRCA mutations in population or hospital based samples of breast cancer patients mainly European ancestry and studies have demonstrated BRCA1/2 mutation between 5% and 10% with early-onset breast cancer. The assessments of familial cancer risk are extremely varied, including families from different ethnic backgrounds with greater or less numbers of affective relatives at varying ages. And estimates of penetrance for BRCA1 and BRCA2 mutations range from 36% to 85% for breast cancer, and 16% to 60% for ovarian cancer. For molecular correlations, BRCA1 cancers were shown to be more often estrogen receptor negative, more high grade tumors and more frequent mutations in p53 than nonhereditary cancers. The phenotype for BRCA2-related tumor sappears to be more heterogeneous. The prognosis of BRCA related tumor is elusive, despite of a significantly increased risk of contralateral breast cancer. Surveillance recommendations for women with germline BRCA mutations are necessary and women are encouraged to learn and practice breast self-examination beginning at age 18 and to begin annual mammogram screening at age 25. A number of women with BRCA mutations may consider undergoing surgical procedures (mastectomy and salpingooophorectomy) in attempt to reduce their risk. Nonsurgical options (tamoxifen medication) for the prevention of hereditary breast cancer are currently limited. The choice of whether to undergo genetic testing is difficult one and should be made only after extensive consultation with a professional who is well versed in the counselling and management of families at hereditary risk. And psychological consequences of testing and the potential impact on family dynamics are important considerations that must be individually addressed. Most of above mentioned data are based on studies of European ancestry. To apply these results to Korean patients with breast cancer, we have to collect a lot of data specific to Korean patients. Therefore, it is needed to study many aspects of Korean breast cancer including age specific mutation prevalence, penetrance, molecular correlation, pathology, prognosis, surveillance and prevention options for women with BRCA mutations.

Nowadays administration of bone marrow transplantation is increasing state by developing society and high leukemia incidence. Decrease of relapse and infection rate result from chemo therapy drug development of treatment and strength. So we look for continuos development of treatment. But through before and after BMT, it takes several months by planing and HLA typing matching possibility of BMT. Also, it takes one or two month by duration of BMT and discharge. During BMT, patients experience emotional change-suggering, anxiety, depression and so on-due to changed body image and strictly isolation in special facility. After BMT, the patients also experience stress such as conditions self-care, support from family, concern of relapse risk and so far enlarge mental, economic and physical change surrounding them due to high cost. Accordingly nurses are required high quality of nursing attentive assesment, understanding of patient's environment and consideration, and teaching in administrative work. The study is attempted to establish nursing theory patients' experience in BMT treatment. Research method followed grounded theory methodology by strauss & Corbin. Subjects were 1 adolescent including highschool patient and 6 adults. This study continued from February 1996 through August 1996. All of these subjects were interviewed by this author. Interview were done by long interview technique and observation. Each interview took 1 hour to 2 hours Content of interview was recorded and transcribed later. The data thus collected were analyzed immediately after interviews and fed into the next round of interviews until the data collection reaches the saturation point. In the process of data analysis, "Terribleness" or "Miserableness" was found to be the core phenomenon. Results were composed to 103 concepts. These concepts were grouped into twenty four categories, and then to eleven categories. Categories include "physical burden", "economic burden", "mental distressing", "heartbreaking", "being gloomy", "horror", "being crushed", "feel oppressed", "being exhausted", "family dependent", "support", "previous data for procedure", "inclination", "exploding", "sharing", "mitigation", "bracing oneself", "becoming attached", "dependence", "thanks", "anxiety", and "abandonment". Patients with bone marrow transplantation were revealed to face "terribleness". Terribleness is found to be progressed through the cycle production-coping-solution. Fourteen hypotheses were derived from the integration of categories as follows ; (1) The stronger the term of suffering as perceived by the subjects, the stronger the "terribleness" will be. (2) The more excessive the degree of suffering as perceived by the subjects, the more excessive the "terribleness" will be. (3) If subjects have family dependent "terribleness" is expressed with abusement. (4) If subjects have no family dependent, "terribleness" will be expressed with exposure and suppressing. (5) The more abundant the sufficient support, "terribleness" will be expressed with exposure and suppressing. (6) The less abundant the sufficient support, "terribleness" will be expressed with abusement. (7) The more abundant the previous data, "terribleness" will be expressed with exposure and suppressing. (8) The less abundant the pervious data, "terribleness" will be expressed with abusement. (9) The more introvert the subject's inclination, "terribleness" will be expressed with exposure and suppressing. (10) The more extrovert the subject's inclination, "terribleness" will be expressed with abusement. (11) The more excessive the degree of "terribleness" will be expressed with abusement. (12) The less excessive the degree of "terribleness" it will be expressed with exposure and suppressing. (13) The more expressive the abusment, "terribleness" will be solved despair. (14) The more expressive the exposure and suppressing, "terribleness" will be solved with expectation. On the basis of the patterns that have the four these below were confirmed. 1. If patients felt large amount of terribleness because of severe suffering, they had family dependent. insufficient support, no previous data and their inclination was extrovert, "terribleness" is solved despair with abusement. 2. If patients felt large amount of terrible because of severe suffering family dependent, sufficient support, pervious data, and their inclination was introvert, "terribleness" is solved expectation with suppressing and exposure. 3. If patients felt small amount of terribleness because of little suffering, no family dependent, insufficient support, no previous data, and their inclination was extrovert, "terribleness" is solved despair with abusement. 4. If patients felt small amount of terribleness because of little suffering, no family dependent, sufficient support, previous data, and their inclination was introvert, "terribleness" is solved expectation with exposure and suppressing. On the basis of the above result, in orer to help nurses take good care of their patient, and understands patient's inclination and background, nursing assessment and intervention on life readjustment, and getting support should be required. It is expected that theoretical framework provided by this study, which shows how "terribleness" products, changes, increases and decrease. Therefore public relations, education, counseling emotional support, understanding inclination and exchange of information will have to be accomplished.

In this study, we evaluate the influence of post surface pre-treatments on the bond strength of four different cements to glass fiber posts. Eighty extracted human maxillary central incisors and canines were endodontically treated and standardized post spaces were prepared. Four post pre-treatments were tested: (i) no pre-treatment (NS, control), (ii) sandblasting (SA), (iii) silanization (SI) and (iv) sandblasting followed by silanization (SS). Per pre-treatment, four dual-cure resin cements were used for luting posts: DMG LUXACORE Smartmix Dual, Multilink Automix, RelyX Unicem and Panavia F2.0. All the specimens were subjected to micro push-out test. Two-way analysis of variance and Tukey post hoc tests were performed (α=0.05) to analyze the data. Bond strength was significantly affected by the type of resin cement, and bond strengths of RelyX Unicem and Panavia F2.0 to the fiber posts were significantly higher than the other cement groups. Sandblasting significantly increased the bond strength of DMG group to the fiber posts.
