[Prostatitis studies in China from 2000 to 2020: A Knowledge Atlas-based study on the development trend of contemporary disciplines].

OBJECTIVE: To review and analyze the trend of researches on prostatitis in China in the past two decades. METHODS: We searched the core collection of China National Knowledge Infrastructure (CNKI) for studies on prostatitis, and analyzed the data obtained using Excel, Citespace and VOSviewer. RESULTS: Totally, 1 216 original articles were identified, with 3 271 keywords, ≥3-time high-frequency keywords accounting for 12.9%, with "", "", "chronic prostatitis", "prostatitis", and "" as the top 5 ones, each with a centrality higher than 300. Major prostatitis-related studies focused on the 8 keywords, namely, prostatitis, prostatic fluid, rats, prostate, syndromes, efficacy observation, compound (in traditional Chinese medicine, TCM), and therapeutic application. The included literature involved 2 808 authors, with 402 involved more than twice and most of them in a scattered manner. The major topics of prostatitis studies varied in the past two decades, focusing on TCM therapies, promotion of blood circulation and stasis and comprehensive nursing in 2000－2001, on animal models, CD4+ lymphocytes and other experimental molecules in 2007－2010, on urodynamics, risk factors and specific antigens in 2013－2016, and on literature information resources in 2016. CONCLUSIONS: The immune mechanism remains a hot topic in the future researches on prostatitis. In terms of treatment of the disease, TCM has a potential value, and more practice and studies are required for an optimal combination of TCM and Western medicine. Strengthened collaborative efforts are needed to establish an authoritative source channel for the keywords, and incorporate it into the national standard system, and above all, to integrate the prostatitis study into multi-disciplinary researches, eliminate academic barriers, encourage collaborative innovation with multiple parties, and promote the exchanges and development in this field.

Association Between Medication Adherence and Admission Blood Pressure Among Patients With Ischemic Stroke.

BACKGROUND: Poor medication adherence is one of the most important factors underlying uncontrolled blood pressure, and ensuing hypertension is the leading risk factor for stroke. However, the influence of prestroke medication nonadherence on the admission blood pressure of patients with hypertension who have had an ischemic stroke remains unclear. OBJECTIVE: The aims of this study were to explore the influence of medication nonadherence on the admission blood pressure of patients with hypertension who have had an ischemic stroke and to analyze the reasons for medication nonadherence preceding stroke. METHODS: A sample population of 301 patients with hypertension who have had an ischemic stroke was recruited. A questionnaire was used to investigate sociodemographic data and reasons for nonadherence. The 4-item Medication Adherence Scale was used to investigate prestroke medication adherence. Blood pressure was measured upon patient admission. Logistic regression analysis was used to identify factors influencing adherence. RESULTS: In this cohort, 80.73% of the patients exhibited uncontrolled blood pressure on admission, and 26.58% had undiagnosed hypertension. Of the patients aware of their diagnosis, 75.11% were nonadherent and 10.40% had never used antihypertensive medicines. Uncontrolled admission blood pressure was positively influenced by medication nonadherence. The main causes of nonadherence included forgetfulness (58.08%), lack of belief in the need for long-term antihypertensive treatment (27.27%), and no awareness of the importance of long-term medication (24.75%). CONCLUSIONS: Stroke education in China should focus on patients' poor understanding of the importance for sustained antihypertensive medication adherence to improve blood pressure control and prevent stroke.

Association between health service utilisation of internal migrant children and parents' acculturation in Guangdong, China: a cross-sectional study.

OBJECTIVES: To assess the health service utilisation of internal migrant children in Guangdong, China, and to explore the association between children's health service utilisation and their parents' acculturation. DESIGN: Cross-sectional survey between April and May 2016. SETTING: Six society-run schools of Tianhe and Baiyun districts in Guangzhou City of China. PARTICIPANTS: We recruited all students at grade 7 or 8 and one of their parents who resided in Guangzhou over 6 months without permanent registered residence (hukou) in Guangzhou (1161 pairs completed this survey). 258 children were ill within the past 2 weeks or during the last year. MAIN OUTCOME MEASURES: The main outcome was self-reported health service utilisation. Logistic regression analysis was conducted to explore the association between children's unmet needs for outpatient or inpatient service and their parents' acculturation (categorised into high, middle and low groups). RESULTS: In total, 216 children, or 18.6% of the total subjects, were ill within the past 2 weeks and were in need of outpatient service; 94 children, or 8.1% of the total subjects, were in need of inpatient service. Among them, 17.6% and 46.8% of the migrant children had unmet needs for outpatient and inpatient services, respectively. After controlling for enabling resources and predisposing characteristics, migrant children with parents in the middle-acculturation group (adjusted OR=3.17, 95% CIs 1.2 to 8.3, P<0.05) were more likely to have an unmet outpatient need than high-acculturation or low-acculturation groups, although only statistically significant when comparing with the high-acculturation group. Stratified analysis suggested that this association could be moderated by their family economic status. CONCLUSIONS: Our study suggested that the association between migrant children's health service utilisation and their parents' acculturation was complex and could be moderated by family economic status. Increasing the service utilisation among migrant children requires improving the acculturation and economic status of the parents of internal migrants.
