Objective:To explore the impact of the hospital health literacy environment on patients′ postoperative pain self-management behaviors, aiming to provide insights for hospitals to implement the Comprehensive Pain Management Pilot Work Program in hospitals and to promote self-health management among patients with other diseases or symptoms. Methods:From November to December 2023, a convenience sampling method was used to select postoperative patients from three grade A tertiary general hospitals in Zhejiang Province for an on-site questionnaire survey. The Chinese version of brief health literacy screen (BHLS), short-form health literacy environment scale (SF-HLES) and postoperative pain self-management behavior questionnaire (PPSMB) were used as survey tools to investigate the health literacy level of patients, the health literacy environment of the hospital, and the postoperative pain management behaviors of patients. Two-way ANOVA was used to compare the impact of different dimensions of the hospital health literacy environment on postoperative pain management behaviors among patients with different levels of health literacy. Multiple linear regression analysis was used to explore the relationship between the hospital health literacy environment, individual health literacy, and patients′ postoperative pain self-management behaviors, and to discuss the impact of individual health literacy on patients′ postoperative pain self-management behaviors under different hospital health literacy environments.Results:341 valid questionnaires were collected. The average score of the hospitals′ SF-HLES was (73.62±19.54) points. The average score of the patients′ BHLS was (9.65±2.88) points. The average score of the patients′ PPSMB was (25.99±6.35) points. Two-way ANOVA results showed that the interaction between individual health literacy and the clinical dimension ( F=5.463, P=0.020) and structural dimension ( F=6.470, P=0.011) of the hospital health literacy environment had a statistically significant impact on patients′ postoperative pain self-management behaviors, while the interaction with the interpersonal dimension ( F=0, P=0.984) had no statistically significant impact on pain self-management behaviors. Simple effect analysis indicated that only in the high health literacy environment of the clinical and structural dimensions did the difference in pain self-management behaviors between patients with good health literacy and those with limited health literacy had statistical significance ( P<0.001). Multiple linear regression analysis results showed that for each 1-point increase in the patients′ BHLS score, their PPSMB score increased by 3.74 points ( β1=0.832, P<0.001); for each 1-point increase in the hospital′s SF-HLES score, the patients′ PPSMB score could increase by 0.198 points ( β2=0.610, P<0.001). In a low health literacy environment, individual health literacy did not affect pain self-management behaviors ( P>0.05); however, in a high health literacy environment, for each 1-point increase in the patients′ BHLS score, their PPSMB score correspondingly increased by 4.037 points ( β4=0.317, P<0.001). Conclusions:The positive impact of individual health literacy on pain self-management is contingent upon a high-quality hospital health literacy environment. This suggests that optimizing the hospital health literacy environment is a necessary precondition for implementing the relevant content of the Comprehensive Pain Management Pilot Work Program and can provide a reference for promote self-health management among patients with pain and other diseases or symptoms.

【Objective】 To investigate the expression of optineurin (OPTN) in multiple myeloma (MM) and explore the mechanism and clinical value of OPTN gene in the occurrence and development of MM. 【Methods】 In this study, three gene expression omnibus (GEO) data sets were used to analyze the expression level of OPTN in MM. Clinical bone marrow samples of MM patients were collected. qRT-PCR was used to further verify the expression of OPTN in MM patients. The Kaplan-Meier survival curve and receiver operating characteristic (ROC) curve were used to analyze the value of OPTN in the prognosis and diagnosis of MM. At the same time, MM transcriptome data were downloaded from the Cancer Genome Atlas (TCGA) database. According to the median boundary of OPTN mRNA expression level, the MM patients were divided into OPTN high- and low-expression groups. In order to investigate the possible molecular mechanisms of OPTN in MM, gene set enrichment analysis (GSEA) was made after the differentially expressed genes were filtered using the limma package of the R language. 【Results】 The expression level of OPTN was significantly lower in MM tissues than in normal tissues (P<0.05). OPTN expression level was significantly correlated with International Staging System (ISS) in MM patients (P<0.05). ROC results showed that the expression level of OPTN could distinguish between normal and MM patients. Survival analysis showed that the overall survival (OS) of patients with low OPTN expression was significantly lower than that of patients with high OPTN expression (P<0.05). GO, KEGG and GSEA enrichment analyses indicated that OPTN might affect apoptosis and autophagy, and regulate cellular immune response by regulating Nod-like receptors, NF-κB, TNF and RAS/MAPK pathways. 【Conclusion】 Low expression of OPTN in MM is associated with poor prognosis of patients, and thus may be an important potential biomarker for the diagnosis and treatment of MM.

Abstract Health literate schools (HeLit-Schools) play a significant role in fostering students health literacy. The paper elucidates the background and conceptual connotations of HeLit-Schools, and analyzes how HeLit-Schools effectively integrate and enhance the health literacy of schools in three aspects: philosophy and core drivers, strategy and method implementation, as well as evaluation mechanisms and standard setting. Furthermore, the paper explores the implications of foreign HeLit-Schools research and practice for China under the context of "Healthy China" construction, as well as the key strategies for Chinese schools in the implementation of HeLit-Schools, aiming to provide a new perspective and theoretical support for Chinese schools to practice the "Healthy China initiative" and strengthen school construction from the perspective of health literacy.

Objective:To search for and summarize the best evidence on non-pharmacological interventions for orthostatic hypotension in patients with Parkinson disease.Methods:Based on the 6S model, the relevant guidelines, clinical decisions, evidence summaries, systematic reviews and expert consensus on non-pharmacological interventions for orthostatic hypotension in Parkinson disease patients were systematically retrieved from domestic and foreign databases. The search time was from the establishment of the database to December 2022. Two researchers independently screened the literature, evaluated the quality of the included literature, and extracted and summarized evidence that met the quality standards.Results:A total of 15 articles were included, including 4 guidelines, 2 clinical decision-making articles, 1 evidence summary article, 3 systematic evaluations and 5 expert consensus articles. A total of 24 pieces of best evidence were summarized from 7 aspects, including purpose, evaluation, capacity intervention, exercise intervention, posture intervention, physical intervention, health education and support.Conclusions:The best evidence on non-pharmacological intervention for orthostatic hypotension in patients with Parkinson disease can provide a reference for the practice of clinical medical staffs. It is suggested to apply the best evidence in combination with the patient's condition, preference and clinical environment, so as to reduce the incidence of orthostatic hypotension in patients with Parkinson disease and to ensure the safety of patients.

Objective: To analyze the contribution and interaction of polycyclic aromatic hydrocarbons (PAH)-DNA adducts and changes of telomere length (TL) on missed abortion. Methods: From March to December 2019, patients with missed abortion in the First Hospital of Shanxi Medical University and pregnant women with normal pregnancy but voluntary abortion in the same department during the same period were selected and divided into a case group and a control group. Questionnaire was used to investigate the general situation and the pregnancy situation of the subjects. The abortion villi were collected and the content of PAH-DNA adducts and TL was detected. Logistic regression model was used to analyze the associated factors of missed abortion. R epiR package and Mediation package were used to analyze the effect and relationship between PAH-DNA adducts and TL on missed abortion. Results: The age of the subjects was(29.92±5.69)years old. The M(Q₁,Q₃)of PAH-DNA adducts was 453.75(404.61, 504.72) pg/ml. The M(Q₁,Q₃)of TL was 1.21(0.77, 1.72). The content of PAH-DNA adducts in the case group was higher than that in the control group (Z=-2.10, P=0.036), while the TL was lower than that in the control group (Z=-4.05, P<0.001). Multivariate logistic regression showed that low, medium and high levels of PAH-DNA adducts (OR=3.17,95%CI:1.41-7.14;OR=2.85,95%CI:1.25-6.52;OR=2.46,95%CI:1.07-5.64), and long, medium and short levels of TL (OR=2.50,95%CI:1.11-5.63;OR=3.32,95%CI:1.45-7.56;OR=3.22,95%CI:1.42-7.26) were all risk factors for missed abortion. The medium level of PAH-DNA adducts had a 2.76-fold higher risk of shortened TL than those with the lowest level, and no mediating role of TL was found. The stratified analysis showed that when the TL level was longer (>1.21), the low and high levels of PAH-DNA adducts were associated with missed abortion (all P<0.05); when the TL level was shorter (<1.21), the medium level of PAH-DNA adducts was associated with abortion (P=0.025). At lower levels of PAH-DNA adducts, no effect of TL on missed abortion was observed, while, at higher levels, TL was strongly associated with missed abortion (OR=7.50,95%CI:1.95-28.82;OR=6.04,95%CI:1.54-23.65;OR=9.05,95%CI:2.34-35.04). The interaction analysis found that the AP was 0.72 (95%CI: 0.46-0.99), and the SI was 5.21 (95%CI: 2.30-11.77). Conclusion: The high level of PAH-DNA adducts and shortened TL may increase the risk of missed abortion, and there may be a positive additive interaction between the two factors on missed abortion.

By investigating the contamination status and predicting the exposure risk of mycotoxin in Coicis Semen, we aim to provide guidance for the safety supervision of Chinese medicinal materials and the formulation(revision) of mycotoxin limit standards. The content of 14 mycotoxins in the 100 Coicis Semen samples collected from five major markets of Chinese medicinal materials in China was determined by UPLC-MS/MS. The probability evaluation model based on Monte Carlo simulation method was established after Chi-square test and One-way ANOVA of the sample contamination data. Health risk assessment was performed on the basis of margin of exposure(MOE) and margin of safety(MOS). The results showed that zearalenone(ZEN), aflatoxin B_1(AFB_1), deoxynivalenol(DON), sterigmatocystin(ST), and aflatoxin B_2(AFB_2) in the Coicis Semen samples had the detection rates of 84%, 75%, 36%, 19%, and 18%, and the mean contamination levels of 117.42, 4.78, 61.16, 6.61, and 2.13 μg·kg~(-1), respectively. According to the limit standards in the Chinese Pharmacopoeia(2020 edition), AFB_1, AFs and ZEN exceeded the standards to certain extents, with the over-standard rates of 12.0%, 9.0%, and 6.0%, respectively. The exposure risks of Coicis Semen to AFB_1, AFB2, ST, DON, and ZEN were low, while 86% of the samples were contaminated with two or more toxins, which needs more attention. It is suggested that the research on the combined toxicity of different mycotoxins should be strengthened to accelerate the cumulative exposure assessment of mixed contaminations and the formulation(revision) of toxin limit standards.

This study aimed to establish a method for synchronous detection of 14 mycotoxins in Pseudostellariae Radix and investigate its contamination with mycotoxins, so as to provide technical guidance for monitoring the quality of Chinese medicinal materials and medication safety. The sample was extracted with 80% acetonitrile in an oscillator for 1 h, purified using the modified QuEChERS purifying agent(0.1 g PSA + 0.3 g C_(18) + 0.3 g MgSO_4), and separated on a Waters HSS T3 chromatographic column(2.1 mm×100 mm, 1.8 μm). The gradient elution was carried out with 0.1% formic acid in water and acetonitrile, followed by the scanning in the multi-reaction monitoring(MRM) mode and the analysis of mycotoxin contamination in 26 Pseudostellariae Radix samples. The recovery rates of the established method were within the range of 82.17%-113.6%, with the RSD values less than 7% and the limits of quantification(LOQ) being 0.019-0.976 μg·kg~(-1). The detection rate of 14 mycotoxins in 26 batches of medicinal materials was 53.85%. The detection rate of sterigmatocystin(ST) was the highest, followed by those of zearalenone(ZEN), aflatoxin G_2(AFG_2), fumonisin B_1(FB_1), HT-2 toxin, and nivalenol(NIV). Their respective detection rates were 38.46%, 26.92%, 23.08%, 11.54%, 11.54%, and 7.69%, with the pollution ranges being 1.48-69.65, 0.11-31.05, 0.11-0.66, 0.28-0.83, 20.86-42.56, and 0.46-1.84 μg·kg~(-1), respectively. The established method for the detection of 14 mycotoxins is accurate, fast and reliable. The research results have very important practical significance for guiding the monitoring and prevention and control of exogenous fungal contamination of Chinese medicinal materials.
