Popularizing health knowledge scientifically and improving people’s health literacy level is one of the most economical and effective measures to improve people’s health level. In carrying out health science popularization work, public hospitals, as the main force of popular science, have some problems, such as lack of enthusiasm of medical staff, unfamiliarity with new means and laws of communication, too professional output and poor popularization effect. In recent years, West China Hospital of Sichuan University has taken the “West China Hospital Popular Medicine Readings” as the popular science brand, and through creating management mode, innovative creation mode, strengthening continuous training and system construction, it has formed a health science brand and explored a set of reproducible long-term mechanism for health science popularization. This article deeply analyzes the problems faced by public hospitals in developing health science popularization work, taking the work mode and achievements of West China Hospital as an example, and explores a new way for other public hospitals, especially small and medium-sized public hospitals, to develop health science popularization work.
Objective To systematically review literature on the influencing factors related to adolescent sub-health problems. Methods We electronically searched the following four databases including CBM, VIP, CNKI and WanFang Data to collect Chinese literature on adolescent sub-health status and problems in China published before May 2012. Two reviewers independently screened literature, extracted data, and cross checked records. Then qualitative analysis was applied. Results According to the inclusion and exclusion criteria, 41 cross-sectional studies were included. The results of qualitative analysis showed that the influencing factors of adolescent sub-health could be classified into four categories including social factors, family factors, school factors, and interpersonal relationships. The main ones were social support, employment pressure, family economic conditions, learning burden, unhealthy habits, etc. Conclusions There are many influencing factors of adolescent sub-health with interaction. Due to the limitation of the included studies, more prospective cohort studies are needed to provide high quality evidence.
An increasing number of health system researchers use systematic review to synthesize research evidence to inform the development of health policies at global and national levels. However, there are methodological challenges facing the health system research in undertaking systematic reviews of health policy literatures. This paper explored the constraints and promise of systematic review as a tool for evidence-based health system research in developing countries. It introduced the systematic review method and its evolution in health research over the past decades. The paper then discussed the definition of health system research, as system science, and contrasted its features/characteristics to those of medical research. It discussed and analyzed if the systematic review could be an effective tool for evidence-based health system research, particularly in developing countries. The paper concludes that the systematic review may be a very useful tool that can be used for evidence-based health system research to address specific policy issues; however, research on some health system/policy issues may not be appropriate to use the systematic review at all.

Objective To summarize the donor factors and experimental factors that affect adipogenic differentiation of adipose derived stem cells, so as to provide reference for adipogenic differentiation of adipose derived stem cells. Methods The related research literature about donor factors and experimental factors affecting adipogenic differentiation of adipose derived stem cells in recent years was extensively reviewed and summarized. Results There are a lot of donor factors and experimental factors affecting adipogenic differentiation of adipose derived stem cells, but some of the factors are still controversial, such as donor age, health status, adipose tissue of different parts, and so on. These factors need to be further studied. Conclusion The donor factors and experimental factors that affect adipogenic differentiation of adipose derived stem cells should be deeply studied and the controversial issues should be clarified to lay a solid foundation for the application of adipose derived stem cells in adipose tissue engineering.
In the era of we-media, the external publicity work of hospitals has some problems, such as the content deviating from the needs of the audience, the internal and external publicity platforms being not separate, the synchronized operation of diversified platforms being difficult, and the stereotyped expression mode affecting the communication effect. Based on the practical experience and remarkable achievements of West China Hospital of Sichuan University in we-media construction, this paper puts forward that public hospitals should choose suitable content, channels, and ways of expression in order to give full play to we-media in their external publicity work.
ObjectiveTo investigate the role and mechanism of S100A8/A9 in rat model of chronic obstructive pulmonary disease (COPD). Methods Twelve Wistar rats were randomly divided into a normal control group and a COPD group. The COPD model was established by exposing the rats to cigarette smoke and injected lipopolysaccharide (LPS) in bronchus for 1 month. The pathological changes of the lung tissue were observed under light microscope, and the emphysema indexes of pulmonary mean linear intercept (MLI), mean alveolar numbers (MAN) and pulmonary alveolar area (PAA) were analyzed by image analysis system. The concentrations of S100A8/A9 in serum and bronchoalveolar lavage fluid (BALF) were measured by enzyme linked immunosorbent assay. The mRNA expression levels of S100A8, S100A9, Toll-like receptor-4 (TLR4) and myeloid differentiation factor 88 (MyD88) of lung tissues were measured by real time polymerase chain reaction. The protein expressions of S100A8/A9, TLR4 and MyD88 of lung tissues were detected by immunohistochemistry. Results After cigarette smoking and LPS injection for 1 month, the rat lung tissue appeared in accordance with the typical pathological changes of COPD. The MLI, MAN and PAA had obvious difference compared with the normal control group (P<0.05). The concentrations of S100A8/A9 protein in BALF and serum of the COPD group were obviously higher than those of the normal control group (P<0.05). The levels of S100A8, S100A9, TLR4 and MyD88 mRNA of lung tissues in the COPD group were obviously higher than those in the normal control group (P<0.05), and the expression levels of S100A8 and S100A9 mRNA were positively correlated with the expression levels of TLR4 and MyD88 mRNA respectively (P<0.05). The levels of S100A8/A9, TLR4 and MyD88 protein of lung tissues in COPD group were obviously higher than those in normal control group (P<0.05), and the levels of S100A8/A9 protein were positively correlated with the levels of MyD88 and TLR4 protein (P<0.05). Conclusions As a new inflammatory mediator, S100A8/A9 may be involved in the occurrence and development of COPD. By up-regulating the expression of TLR4 and MyD88, the classical TLR4-MyD88 inflammatory pathway is activated, thus promotes the occurrence and development of COPD.
ObjectiveTo systematically review the relationship between polycyclic aromatic hydrocarbons (PAHs) and emotion and behaviors in children and adolescents. MethodsThe PubMed, EBSCO, Web of Science, CBM, VIP, WanFang Data, OVFT, Proquest Psychological database and CNKI databases were electronically searched to collect studies on the relationship between PAHs and emotion and behaviors in children and adolescents from inception to October 20, 2022. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. A qualitative systematic review was then performed. ResultsA total of six cohort studies were included, five studies involving maternal exposure during pregnancy, found that maternal exposure to PAHs during pregnancy was associated with an increase in childhood anxiety/depression syndrome, attention problems, social withdrawal, social competence, social problems, orientation/regulation, withdrawal behaviors, and autism-related behaviors. Another study of exposure in school-age children found that PAHs exposure was associated with poorer attention performance in school. Results of other emotional behaviors were inconsistent, or no association was found. ConclusionCurrent evidence shows that PAHs have certain effects on emotional behaviors of children and adolescents. Due to the limited quality and quantity of the included studies, more high-quality cohort studies are required to verify above conclusion.
ObjectiveTo construct an evaluation index system for the dissemination influence of new media health science popularization, providing a quantitative evaluation tool for comprehensively assessing the dissemination influence of health science communication works. MethodsMeta integration, Delphi method and analytic hierarchy process (AHP) were used to build a preliminary evaluation index system, form a framework of the evaluation index system, and calculate the weight values of the evaluation indexes, respectively. ResultsA total of 18 studies were included through retrieval. On the basis of preliminary evaluation index system, ten experts in related professional fields were invited to participate in two rounds of expert consultation, resulting in an evaluation index system framework that includes 2 first-level indicators, 4 second-level indicators, and 9 third-level indicators. ConclusionA preliminary evaluation index system for the dissemination and influence of new media health science communication works, which is reliable, universally applicable, and has a reasonable structure, is constructed.
ObjectiveTo systematically review the influence of childhood psychosocial stress on pubertal emotional and behavioral problems. MethodsThe PubMed, OVID, EBSCO, Web of Science, CBM, VIP, WanFang Data and CNKI databases were electronically searched to collect studies on the relationships between childhood psychosocial stress and pubertal emotional and behavioral problems from inception to February 29, 2024. Two reviewers independently screened the literature, extracted data and assessed the risk of bias in the included studies. Qualitative methods were then used to analyze the data. ResultsA total of 41 cohort studies were included. The outcomes of 19 studies involved pubertal emotional problems, 26 studies involved behavioral problems, and 7 studies involved overall problems. The results showed that depression (14/19) and anxiety (8/19) were the most commonly reported emotional behaviors. Most studies (17/19) showed that childhood psychological stress had a positive predictive effect on pubertal emotional problems. Behavioral problems involved many outcomes, including smoking, drinking, illegal substance use, self-injurious behavior, suicide, externalizing behavior, criminal behavior, bullying behavior, sexual behavior, mobile phone dependence, etc. However, few studies were on the same behaviors, and the relationship between childhood psychosocial stress and behavioral problems was unclear. ConclusionChildhood psychosocial stress may have a positive predictive effect on depression and anxiety. The associations between childhood psychosocial stress and pubertal behavioral problems and other emotional problems remain to be determined by more studies.
