Objective: To investigate the awareness of human papillomavirus (HPV) vaccine knowledge among women in Hainan Province and the willingness to receive HPV vaccination among women and their daughters, so as to provide insights into HPV vaccine promotion and cervical cancer control. Methods: Women aged 20 to 64 years who participated in the cervical cancer screening program in Hainan Province from July 2021 to February 2022 were enrolled, and participants' demographics, awareness of knowledge about HPV vaccine, and willingness to receive HPV vaccination among themselves and their daughters using a questionnaire survey. The factors affecting willingness to receive HPV vaccination were identified using a multivariable logistic regression model. Results: A total of 4 300 questionnaires were allocated and 4 023 valid questionnaires were recovered, with an effective recovery rate of 93.56%. The respondents had a mean age of (35.52±6.48) years, and their daughters had a mean age of (8.93±4.83) years. There were 826 participants knowing HPV vaccine-related knowledge, with an awareness rate of 20.35%. The proportions of willingness to receive HPV vaccination were 75.07% among respondents and 71.36% among their daughters. Multivariable logistic regression analysis identified age (20 to <30 years, OR=1.474, 95%CI: 1.167-1.862; 30 to <40 years, OR=1.455, 95%CI: 1.199-1.765), urban-registered residence (OR=1.251, 95%CI: 1.016-1.541), monthly household income (3 000 to <5 000 Yuan, OR=1.568, 95%CI: 1.314-1.873; 5 000 Yuan and more, OR=1.231, 95%CI: 1.014-1.496), affordable fees for a single dose of HPV vaccination (100 to <500 Yuan, OR=1.358, 95%CI: 1.159-1.590; 500 Yuan and higher, OR=1.609, 95%CI: 1.188-2.180), and awareness of HPV vaccine-related knowledge (OR=4.473, 95%CI: 3.416-5.855) as factors affecting respondents' willingness to receive HPV vaccination, and participation in New Rural Cooperative Medical Insurance (OR=1.652, 95%CI: 1.087-2.511), affordable fees for a single dose of HPV vaccination (100 to <500 Yuan, OR=1.905, 95%CI: 1.633-2.221; 500 Yuan and higher, OR=1.683, 95%CI: 1.275-2.223), awareness of HPV vaccine-related knowledge (OR=3.625, 95%CI: 2.847-4.615), daughter's active request for HPV vaccination (OR=1.695, 95%CI: 1.293-2.222), and frequency of sexual health education for daughters (frequently, OR=2.142, 95%CI: 1.789-2.564; occasionally, OR=1.707, 95%CI: 1.416-2.059) as factors affecting the willingness to receive HPV vaccination among respondents' daughters. Conclusions The awareness of HPV vaccine-related knowledge is low among women aged 20 to 64 years in Hainan Province, and the women's and their daughters' willingness to receive HPV vaccination is associated with age, household registration, economic level, price of HPV vaccine and awareness of HPV vaccine-related knowledge.

OBJECTIVETo compare the difference of clinical efficacy on sleeping disorder in the children with encephalopathy between the combined therapy of acupuncture at head points and seed-pressure at ear points and the simple acupuncture at head points.

METHODSThirty cases of sleeping disorder induced by encephalopathy werei randomized into an observation group and a control group, 15 cases in each one. In the observation group, the combined therapy of acupuncture at head points and seed-pressure at ear points was adopted. The head points in cluded Sishencong (EX-HN 1), Shenting (GV 24) and Benshen (GB 13). The ear points were the positive reactive sites in the cymba and cavum conchae. In the control group, acupuncture was applied simply to the acupoints on the head. The treatment was given once on every Tuesday and Friday a week separately, 30 min each time. Totally, 16 treatments were required. Children's sleeping habit questionnaire (CSHQ) was used to observe the sleep improvements and the efficacy in the patients of the two groups.

RESULTSIn the observation group, the results of sleep resistance, sleep anxiety, night sleep wake, parasomnias, sleep dyspnea, daytime somnolence and the total score after treatment were all improved apparently as compared with those before treatment (all P<0. 05). In the control group, the results of night sleep wake, parasomnias, daytime somnolence and the total score after treatment were improved apparently than those before treatment (all P<0. 05). In the observation group, the results of sleep resistance, sleep dyspnea and the total score after treatment were better than those in the control group (all P<0. 05) and the scores of sleep anxiety and daytime somnolence in the control group were better than those in the observation group after treatment (both P<0. 05).

CONCLUSIONThe combined therapy of acupuncture at head points and seed-pressure at the positive reactive sites in the cymba and cavum conchae achieves the superior efficacy on sleep resistance and sleep dyspnea as compared with the simple acupuncture. The efficacy of simple acupuncture is more satisfactory on sleep anxiety and daytime somnolence.

Abstract： Objective　To establish a screening-diagnosis-evaluation system of neonatal congenital heart disease (CHD) suitable for Hainan Province based on the application of percutaneous blood oxygen saturation measurement and cardiac auscultation screening, and to provide a basis for further promotion of the evaluation effect. Methods　Screening agencies (all midwifery institutions) used the "double index method" to screen newborns for congenital heart disease. Those who were screened positive for any index were transferred to diagnostic institutions (the people's hospitals of all cities and counties and some tertiary hospitals) for echocardiography examination within 1 week. Those with abnormal results were transferred to the treatment institution (two tertiary hospitals) for reconfirmation and evaluation. All data were managed online. Results　In this study, 96 913 newborns born in midwifery institutions in 19 cities and counties were screened, with a response rate of 99.44%. The ratio of male infants (50 836) to female infants (46 077) was 1.10∶1. A total of 2 284 positive patients were screened by dual index method, and ultrasound diagnosis was performed, with the rate of cardiac ultrasonography of 98.07% (2 240/2 284) and a high response rate. A total of 238 cases of congenital heart disease were diagnosed (incidence rate of 0.25%), with the top three main types were ventricular septal defect, atrial septal defect, and patent ductus arteriosus. The sensitivity (88.24%) and Youden index (0.86) of dual-indicator screening for CHD detection were significantly higher than the other separate indicators. Through Kappa consistency test analysis, the consistency of dual-indicator screening with simple heart murmur screening results was excellent, with a Kappa coefficient value of 0.835 (>0.75); the consistency of dual-indicator screening and simple POX screening results was good, with a Kappa coefficient value of 0.429 (between 0.40-0.75), and the differences were statistically significant (P<0.001). By the end of the study, 136 children had undergone open-chest/occlusion surgery, with good postoperative recovery, and the rest were followed up. Conclusions　The neonatal CHD screening-diagnosis-assessment technology system established in this study, with close connections between various blocks, high screening response rate and echocardiography examination rate, is beneficial for the early diagnosis and treatment of CHD children, and has certain application value in institutions at all levels in Hainan Province, and is worth further promotion.

Objective:To develop a biomimetic nanoparticle probe of hematoporphyrin monomethyl ether (HMME) coated with breast cancer cell membrane, to observe its ability to target homologous breast cancer cells in vitro, and to investigate its effect of enhanced photoacoustic imaging and sonodynamic therapy (SDT) for breast cancer in vitro.Methods:The cell membrane of breast cancer 4T1 was extracted by chemical cleavage and repeated freezing and thawing. Then the HMME-coated polylactic acid-glycolic acid copolymer biomimetic nanoparticle was prepared by double emulsification and extrusion. The basic characteristics of nanoparticles were detected. The target ability of nanoparticles to homologous breast cancer cells and the enhancement of photoacoustic imaging were observed in vitro. Singlet oxygen sensor green (SOSG) was used to verify the reactive oxygen species (ROS) production of nanoparticles, and its SDT effect on breast cancer cells was evaluated by CCK8 cytotoxicity assay.Results:The size of the prepared CHP-NPs was uniform, the morphology was spherical "core-shell structure" , the particle size was (275.23±8.25)nm, and the surface potential was (-18.43±0.45)mV. It was observed that CHP-NPs could target homologous 4T1 cells under laser confocal microscopy. In vitro photoacoustic imaging experiments show that the photoacoustic signal of nanoparticles increases with the increase of its concentration. According to SOSG probe detection, CHP-NPs could produce ROS under ultrasonic irradiation.When CHP-NPs was incubated with 4T1 cells alone and no ultrasonic irradiation was used, the cell survival rate was not significantly affected. When the concentration was 0.6 mg/ml, the cell survival rate was still 95%. After ultrasonic irradiation, CCK8 experiment showed that the CHP-NPs had a significant SDT effect on breast cancer cells.Conclusions:The biomimetic nanomolecular probe of breast cancer cell membrane is successfully prepared. The probe has good ability to target homologous tumor, and can significantly enhance tumor photoacoustic imaging and SDT effect.

Abstract: Objective To explore the trend of maternal mortality in Hainan Province during the period of 2003-2022, both in the province and in urban and rural areas, and to forecast the maternal mortality rate for the period 2023-2025. Methods The 2003-2022 data collected from Hainan Province's three-tier network for maternal mortality surveillance was examined using the Chi-square test for trend (CMH) to analyze the province-wide and urban-rural maternal mortality trends. The time series model forecasting using exponential smoothing was used to predict the maternal mortality rate in Hainan Province from 2023 to 2025. Results　From 2003 to 2022, a total of 201 011 616 live births and 463 maternal deaths were reported in Hainan Province, with a maternal mortality rate of 23.03 per 100 000. Over 20 years, the maternal mortality rate in Hainan Province showed a downward trend, with an annual rate of decline of -4.13%. The rate decreased significantly during this period.. From 2003 to 2022, the maternal mortality rate in rural areas of Hainan Province was 25.74/100 000 (373/1 448 943), and it was significantly higher than that in urban areas, 16.04/100 000 (90/561 173). In the first 10 years, the gap between urban and rural areas progressively reduced, but it widened significantly in the last decade, especially after 2017. The maternal mortality rate was significantly lower in urban than rural areas, and the differences had statistical significance. The annual rates of decline in maternal mortality in Hainan Province and in urban and rural areas from 2003 to 2022 were -5.0% and -3.71%, respectively, showing a negative growth with the decrease rate in rural areas lower than urban areas. The maternal mortality rate in Hainan Province showed a fluctuating downward trend, different from the stable trend of national decrease. The mortality rates for direct obstetric causes of death (233 cases) and indirect obstetric causes of death (230 cases) were 11.59/100 000 and 11.44/100 000, respectively. The results of the maternal mortality review showed a predominance of avoidable deaths (315 cases, 68.03%). Brown's cubic exponential smoothing predicted the maternal mortality rate in Hainan Province for 2023-2025 as 9.45/100 000, 8.17/100 000, and 6.89/100 000. Conclusions　The maternal mortality rate in Hainan Province is largely influenced by maternal deaths in rural areas, and maternal health care in rural areas should be emphasized. Measures such as intervening to address the main factors influencing avoidable maternal deaths, strengthening high-risk maternal management, improving the level of critical maternal care, and providing subsidies for critical maternal care can sustainably reduce the maternal mortality rate in Hainan.

Medical record information is the core data source for diagnosis related groups(DRG)payment, and high-quality of medical record information is the foundation for DRG payment. The development of medical record management towards medical record information management, pushes up the demand for high-quality medical record information management professionals in hospitals. The conventional practice of professional training had resulted in such setbacks as professionals mismatch, long pre-employment training period, and large demand for continuing education. Based on the triple helix model theory, the study established a production-education integration training mode of university-government-hospital for medical record information management professionals. Capacity development was set as the goal and job demand as the guidance, for effectively integrating the educational resources, and promoting the model of " posts linked to training, employment following graduation" production-education integration training. The aim is to expand the quantity of talent team and improve the quality of talent training, thus effectively easing the shortage of medical record information management professionals.

Abstract: Objective　To evaluate the free thalassaemia screening programme for preconception and pregnancy in Hainan Province, and to provide a theoretical basis for optimizing the screening process for thalassaemia. Methods From November 2020 to July 2021, a survey was conducted on 10 396 adults with Hainan household registration who participated in the Epidemiological Survey of Thalassemia in Hainan Residents in 19 cities and counties of Hainan Province. All of them underwent routine blood tests, haemoglobin electrophoresis tests and genetic tests for thalassaemia. The optimal diagnostic cut-off values for mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and haemoglobin adult type 2 (HbA2) were determined using screening test indexes such as receiver operating characteristic curve and sensitivity. The diagnostic effectiveness of different primary screening programs for thalassemia gene carriers was evaluated. Results Using the existing MCV single-indicator thalassemia primary screening protocol in Hainan Province, where individuals with MCV<82 fL undergo thalassemia gene testing, resulted in a high missed diagnosis rate (34.06%) and low sensitivity (65.94%). The optimal cut-off values for MCV screening for alpha-and beta-thalassaemia were 84.45 fL and 79.05 fL, respectively; the optimal cut-off values for MCH screening for alpha-and beta-thalassaemia were 27.95 pg and 25.15 pg, respectively. The optimal cut-off value for HbA2 screening for alpha-thalassaemia was less than 2.55% and greater than 3.35% for beta-thalassaemia. The "combined HbA2 or MCH or MCV screening protocol" with the cut-off values recommended in this study had a better performance in primary screening for thalassemia, with the highest sensitivity (92.96%) and negative predictive value (92.67%) and the lowest underdiagnosis rate (7.04%), statistically significant differences compared with the existing protocol (P<0.05). Conclusions The current process of screening for thalassemia in Hainan Province may lead to missed diagnoses. The combined use of MCV, MCH and HbA2 for thalassemia screening, adopting locally suitable cutoff values for primary screening indicators, can improve the incidence of missed reporting of thalassemia and enhance diagnostic effectiveness.

Objective:To investigate the current situation of the " Internet plus nursing services" for the elderly in Ningbo, and evaluate the promotion effect of the pilot policy, for reference to further optimize such service policy of China nationwide.Methods:The data came from the orders for " Internet plus nursing services" by elderly users over 60 years on the " cloud hospital" platform in Ningbo from 2016 to 2021. Descriptive analysis was used to study major demographic information, types of service items and number of person-times of the elderly users; The promotion effect of the pilot policy on " Internet plus nursing services" for the elderly in 2019 was analysed by Chow test.Results:The number of elderly users increased from 76 person-times in 2016 to 5 923 person-times in 2021, accumulating up to 12 209 person-times. The number of nursing service items increased from 18 in 2016 to 36 in 2021. The person-times of users of common clinical nursing and specialized nursing service items were 11 850 and 359 respectively. After the pilot policy was issued, the number of service items and the number of users were significantly increased in 2020( P<0.05). Conclusions:The development of " Internet plus nursing services" for the elderly in Ningbo had achieved certain results, especially with the promotion of the pilot policy in 2019, the types of service items and the number of elderly users had increased year by year. In the future, we should continue to focus on the elderly living alone and other special elderly groups with the support of relevant policies, further expand the scale of elderly users, improve the types of service items, and optimize the charging standards to help China′s healthy aging process.

Moral injury is a kind of trauma symptom caused by the impact of external immoral events on the internal moral value system of individuals or groups. Its origin lies in the deviation between individual’s internal moral schema and external moral situation. As a collection of moral consciousness units with value orientation in the regular activities of individuals in the moral environment, moral schema is composed of periphery and core. Moral schema realizes the domination of moral ego by supervising individual’s speech and behavior, exercising moderate control over individuals based on moral practice, and examining individual behavior with self-guilt as the tool of judgment. Moral schema is selective about what happened and acts as a filter for trauma events. Based on this, individuals can interpret or be subverted by moral events, thus playing a preventive role in moral injury.
