Objective:To understand the factors influencing new infections of 9-valent vaccine-type human papillomavirus (9-valent type HPV) among men who have sex with men (MSM) in Urumqi City and to construct a prediction model of individual dynamics of new infections of 9-valent type HPV among MSM.Methods:In this study, a snowball method was adopted to recruit MSM in Urumqi City to establish a dynamic cohort, and participants were followed up every 6 months from 2016 to 2023, and perianal exfoliated cells were collected for HPV genotyping; joint models were established using the number of same-sex sexual partners in the last six months and the number of anal intercourse in the last one week as longitudinal variables, respectively, and joint models were utilized to analyze the influence factors of 9-valent HPV new infections in MSM individuals were analyzed by the joint model; the predictive efficacy of the model in the follow-up period was evaluated by using the time-dependent receiver operating characteristic area under the curve (AUC) values. Based on the prediction model, two study participants were randomly selected for individual dynamic prediction of new-onset HPV infections of 9-valent type types.Results:MSM with at least two follow-up visits 579 individuals were included in the analysis. The results of the two joint models showed that being divorced/widowed [hazard ratio ( HR)=1.544, 95% CI: 1.033-2.233], having a sexual behavior style of being the inserted party ( HR=1.366, 95% CI: 1.053-1.764), and having a history of STDs ( HR=1.659, 95% CI: 1.057-2.558) increased the 9-valent types of new HPV infections risk. The results of the shared parameter of the joint model of the number of same-sex partners in the last six months showed that each 2.72 increase in the number of same-sex partners in the last six months was associated with a 28.2% increase in the risk of new 9-valent HPV infections in MSM individuals ( HR=1.282, 95% CI: 1.065-1.540). The time-dependent AUC results showed that the joint model for the number of same-sex sexual partners in the last six months (0.808 0) predicted better performance than the joint model for the number of anal intercourse in the last one week (0.750 0). The joint model based on the number of same-sex sexual partners in the last six months for the prediction of MSM individual dynamics was consistent with the real situation. Conclusion:The joint model based on the number of same-sex sexual partners in the last six months, sexual behavior, history of STDs, and other risk factors has high accuracy in predicting the risk of new MSM 9-valent HPV infections in Urumqi City, which can provide a scientific basis for the prediction of individual dynamics of new MSM 9-valent HPV infections.

Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

Objective:To describe the epidemiological distribution of hemorrhoids in a physical exami-nation population in China,which could provide evidence for precision prevention and early intervention of hemorrhoids.Methods:Chinese subjects over 18 years of age who underwent a physical examination in a nationwide chain of physical examination centers in 2018 were studied in a cross-sectional design,which collected information by a questionnaire and physical examination results from each subject.The epidemiological distribution of hemorrhoids was described using Logistic models.The gender-,age-,and region-detection rates of hemorrhoids were standardized to the Sixth National Population Census of the People's Republic of China(2010).Results:A total of 2 940 295 adult subjects were included in the study,of whom the average age was(41.7±14.0)years,and 52.6％were females.The standardized detection rate of hemorrhoids was higher for females(43.7％)than that for males(17.7％;P＜0.001)in this study.In the females,the age distribution of hemorrhoids was inverted U-shaped,with the highest standardized detection rate of hemorrhoids in the age group of 30-39 years(63.5％).In the males,the standardized detection rate of hemorrhoids increased along with age,with the highest percentage of 17.2％in the age group of 50-59 years,and the standardized detection rate of hemorrhoids in the age group of 60 and above decreased slightly(P＜0.001 for trend test).The participants with hypertension had a higher standardized detection rate of hemorrhoids than those with normal blood pressure in both males and females(P＜0.001).The standardized detection rate of hemorrhoids showed a positive corre-lation with body mass index(P＜0.001 for trend test in males).Conclusion:The detection rate of hemorrhoids varied to gender,age,obesity,and hypertension status,which could help to identify the risk factors and the high-risk sub-groups,and hence to strengthen health education and early detection accordingly,which could eventually reduce the incidence of hemorrhoids and improve the quality of life and health in the Chinese population.This study was conducted in a physical examination population,and the conclusions of this study should be extrapolated with caution.

Objective:To explore the barriers and facilitators of exercise rehabilitation in patients with atrial fibrillation (AF) after radiofrequency ablation.Methods:From March to August 2022, 285 patients with atrial fibrillation who underwent radiofrequency ablation within three months were recruited from the "Cloud Ward" of the Department of Cardiovascular of the First Affiliated Hospital with Nanjing Medical University by convenience sampling. The Cardiac Rehabilitation Barriers Scale (CRBS) and the Self-efficacy for Exercise Scale (SEE) were used to evaluate the barriers and self-efficacy of patients participating in exercise rehabilitation, respectively. Among them, 22 patients were subjected to semi-structured interviews to extract themes.Results:Among 285 patients with atrial fibrillation, 202 (70.88%) participated in exercise rehabilitation programs. Work/time conflicts, lack of cardiac rehabilitation knowledge, and health/physical function limitations affected the participation of patients in exercise rehabilitation ( P<0.05). Qualitative research extracted three themes that affected the patient's exercise rehabilitation, including capability, opportunity, and motivation. Conclusions:The participation of atrial fibrillation patients in exercise rehabilitation is influenced by multiple factors such as family responsibility, capability, motivation, and opportunity. Medical and nursing staff should comprehensively consider the above factors, develop targeted interventions from all aspects and multiple angles, so as to effectively improve the participation of patients in exercise rehabilitation.

Objective:To implement scoping review of the quality evaluation tool for mobile medical applications (mHealth APP) based on the perspective of health promotion, so as to provide reference for the development or introduction of tools suitable for China and provide inspiration for conducting high quality mHealth APP electronic health intervention research.Methods:Following the method of scoping review, mHealth APP quality evaluation tool development and validation articles published from January 2008 to February 2022 were systematically searched in Cochrane Library, PubMed, EMbase, Institute for Scientific Information (ISI) Web of Science, SCOPUS, CINAHL, PsyINFO, China National Knowledge Infrastructure, VIP, WanFang Data and China Biomedical Literature Database. This study extracted the basic information of the tool and used topic analysis to summarize and integrate the content of the tool items.Results:A total of 27 studies were included, involving 14 mHealth APP quality evaluation tools. The theme analysis process of evaluating the content of items generated a total of 300 primary codes, which were classified into four themes, including software attributes, medical science, behavioral science, and user experience.Conclusions:As a cross disciplinary product, the mHealth app faces multiple challenges in terms of quality. At present, the focus of existing quality evaluation tools varies, among which scientific evaluation originates from the special positioning of mHealth APP and needs to be taken seriously. Different evaluation perspectives may be potential factors that affect the quality evaluation results, and as a key link, users' needs need to be further focused and explored.

Objective:To systematically review the factors affecting adherence with exercise rehabilitation in patients with heart failure, so as to provide a theoretical basis for formulating intervention strategies.Methods:PubMed, Web of Science, Cochrane Library, JBI Library, Embase, CINAHL, Medline, PsycINFO, OVID, CENTRAL, Chinese Biomedical literature Database, China National Knowledge Infrastructure, Wanfang Database and VIP Database were searched for qualitative studies on the influencing factors of exercise rehabilitation adherence from the establishment of the databases to November 31, 2020. The evaluation was performed using the Australian JBI Evidence-Based Health Care Center (2016) qualitative research quality evaluation criteria, and the results were integrated using the Meta integration method.Results:A total of 10 studies were included, 22 research results were extracted, 5 new categories were summarized and 2 integrated results were obtained. The first was the patients' own factors, including physical health status, exercise behavior intention and exercise experience. The second was external factors, including the environment and resources.Conclusions:The adherence of exercise rehabilitation in patients with heart failure is affected by multi-dimensional factors. When formulating intervention strategies, medical staff should start from improving health status of patients, stimulating exercise behavior intention and guiding positive feedback experience, and at the same time provide necessary exercise environment and resource support to improve adherence with exercise rehabilitation in patients with heart failure.

Objective: To evaluate the burden and to describe the characteristics of spatial distribution caused by malignant tumors among different administrative areas in Guangzhou from 2010- 2013. Methods: Based on data from the Cancer Registry system and population in Guangzhou in 2010- 2013, disability-adjusted life year (DALY) was assessed on the disease burden of cancer, in accordance with the method used in the Global Burden of Disease study. Results: The crude incidence rates of cancer appeared as 256.22/10⁵ in 2010-2011 and 270.04/10⁵ in 2012-2013, with the crude mortality rates as 143.17/10⁵ and 148.01/10⁵, respectively, in Guangzhou. Cancers caused 606 238.95 DALYs in 2010-2011 and 623 763.80 DALYs in 2012-2013 for both sexes and 37.63 and 37.81 person year per 1 000 persons, with the standardized DALY rates as 34.51‰, 34.00‰ respectively. Three administrative districts (Yuexiu, Haizhu and Liwan) were with the largest disease burden of cancers that accounted for 45% of the DALYs for the whole Conghua district, with liver cancer was the leading cancer on DALYs, and tracheal, bronchus and lung cancer ranked the first in the other districts. Conclusions In Guangzhou, disease burden caused by cancers was both prominently seen in the newly developed urban area and the old districts. It remains an arduous task to continue programs on control and prevention of cancers in this city.

Objective To establish a non-venous bypass orthotopic liver transplantation model in Bama miniature pigs with high repeatability and stability. Methods Twelve Bama miniature pigs were randomly divided into the donor group (n=6) and recipient group (n=6). Pigs underwent non-venous bypass orthotopic liver transplantation. The time of anhepatic phase during operation was shortened, blood pressure during anhepatic phase was stably maintained, and management of anesthesia and body fluid during operation were strengthened. The operation time, anhepatic phase and survival status of the recipients were observed and recorded. The intraoperative heart rate, mean arterial pressure (MAP) and changes in arterial blood gas analysis were monitored. The perioperative liver function was evaluated. Results Among 6 Bama miniature pigs, 1 died from transplantation failure intraoperatively. The operation time of the remaining 5 pigs was (247±27) min and the time of anhepatic phase was (46±4) min. Three animals survived for more than 2 weeks. Compared with the preanhepatic phase, the heart rate of the animals was significantly faster, MAP was considerably reduced to (46±6) mmHg, blood pH value, base excess (BE) and HCO₃^- level were all significantly decreased and serum level of K⁺ was significantly elevated during the anhepatic phase (all P < 0.05). In the neohepatic phase, MAP of Bama miniature pigs was significantly increased, heart rate was dramatically slower.Blood pH value, BE, HCO₃^- level were significantly increased and serum level of K⁺ was significantly declined (all P < 0.05). During abdominal closure, MAP, blood gas indexes and serum level of K⁺ were almost recovered to those in the preanhepatic phase. Compared with preoperative levels, the levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), lactate dehydrogenase(LDH)and alkaline phosphatase(ALP)were significantly increased after operation (all P < 0.05), the change in AST was the most obvious, and it gradually decreased at postoperative 2 d. The level of γ-gutamyl transferase(GGT) did not significantly elevated. The level of total bilirubin (TB) was evidently elevated at postoperative 5 d. Compared with the preoperative levels, the levels of total protein (TP) and albumin (ALB) were significantly decreased after operation (both P < 0.05), and began to gradually increase at postoperative 1 d. Conclusions The non-venous bypass orthotopic liver transplantation model of Bama miniature pig is convenient, with highly reproducible and survival rate, which can be utilized as a standardized liver transplantation model.
