Narrative is the cornerstone of interpersonal relationships and life safety. However， its important value in daily life， school education， health management， personal happiness， career development， and other aspects has been ignored. The narrative ecology of families， schools， hospitals， workplaces， and elderly care institutions is worrying， the narrative connection between parent-child and intergenerational is broken， the narrative nature of adolescents is ignored， the narrative demands of patients are neglected， narrative relationships in the workplace are indifferent， and the narrative capital of the elderly is idle. These issues have resulted in serious social problems， such as depression and suicide among adolescents， conflicts between doctors and patients， workplace and life burnout among middle-aged people， and the inability of the elderly to achieve healthy aging， which have become a “stumbling block” to the realization of holistic health. Advocating the construction of narrative ecology and interpersonal narrative connections is an important measure of achieving holistic health. Taking the “narrative concept” as the overall framework， and based on the research， education， and practice carried out by the Alliance of Narrative Medicine in Higher Education Institutions， this paper proposed that actively build China’s narrative system of life and health， to enable narrative play an active and dynamic role in the construction of narrative ecology in different spaces， such as the families， the schools， the hospitals， the workplaces， and the elderly care institutions， as well as practically improve the quality of life of the people.

OBJECTIVE: To investigate the therapeutic effects of Banxia Xiexin Decoction (BXD), a herbal medicine formula, on inflammation and the imbalance of the gut microbiota in a rat model of colorectal cancer (CRC) induced by azoxymethane (AOM) /dextran sulfate sodium (DSS). METHODS: A total of 75 male C57BL/6 mice were randomly divided into five groups: normal control group (NC), model group (MODEL), low-dose BXD treatment group (L-BXD), high-dose BXD treatment (H-BXD) group and MS treatment group (MS). BXD and MS were used in CRC mice at the doses of 3.915 g/kg, 15.66 g/kg, 0.6 g/kg for 3 weeks consecutively. Histopathological changes in the colon were observed using hematoxylin-eosin (HE) staining. The content of inflammatory factors in serum was detected by an enzyme-linked immunosorbent assay (ELISA), and the expression of mRNA and protein of genes related to immunity, apoptosis, inflammation, and inflammatory factors was evaluated. Changes in the intestinal flora of mouse fecal were determined based on high-throughput sequencing of the 16S rRNA microbial gene. RESULTS: Compared to the model group, the low-dose BXD and high-dose BXD groups decreased the number of colon tumors, reversed weight loss, and shortened colon length of mice. The pathological examination showed that BXD alleviated the malignancy of intestinal tumors. It also suppressed signal transducer and activator of transcription 3 (STAT3), matrix metalloproteinase-9 (MMP-9), and transforming growth factor beta 1 (TGF-β1) expression, while increasing the expression of the tight junction protein ZO-1 in colon tissues. Additionally, the levels of key pathway proteins involved in inflammation (phosphorylated-STAT3, Bcl-2, COX-2) and cell cycle regulatory molecules (c-Myc and PCNA) were reduced. According to 16S rRNA sequence analysis, BXD enhanced the relative abundance of potentially beneficial bacteria, while that of cancer-related bacteria decreased. CONCLUSION BXD plays a preventive role in developing colorectal cancer; its mechanisms are related to the inhibition of inflammation and tumor proliferation, as well as maintenance of intestinal homeostasis.

Primary liver cancer is the second most common cause of cancer-related mortality, and exploring effective cure methods for liver cancer has become a major challenge. Ferroptosis is an iron-dependent pattern of cell death caused by the accumulation of lipid peroxides. The main mechanisms of ferroptosis include iron metabolism disorders, imbalance of the antioxidant system, and accumulation of lipid peroxides. Inducing ferroptosis of hepatoma cells is regarded as a potential therapeutic strategy for liver cancer. This article aims to outline the key regulatory signaling pathways of ferroptosis in the occurrence and development of liver cancer, and to deeply analyze the potential application prospects of the ferroptosis mechanism in the field of liver cancer treatment.

[Objective]To explore the etiology,pathogenesis,syndrome and treatment of coronary heart disease with depression based on the theory of"the pathways of spirit".[Methods]Starting from the theory of"the pathways of spirit",the relationships among insufficient control of spirit,obstructed the pathways of spirit and impaired heart-spirit functioning in coronary heart disease with depression were analyzed,and the treatment principles at different stages were summarized.[Results]The evolution of coronary heart disease with depression is based on the deficiency of Qi and blood and the insufficient control of spirit.At this stage,Guipi Decoction,Guizhi Longgu Muli Decoction and Jiji Decoction should be used to supplement Qi and blood.The root cause of coronary heart disease with depression is the combination of blood stasis and toxin,which leads to the obstruction of the pathways of spirit.At this stage,Xuefu Zhuyu Decoction or Simiao Yong'an Decoction should be used to dissipate blood stasis and detoxing,combined with large dosage of Astragalus membranaceus to strengthen the healthy Qi without retaining pathogens.The important reason for the deterioration of coronary heart disease with depression is stagnation of Qi which causes impaired heart-spirit functioning.At the obvious stage of Qi stagnation,modified prescriptions such as Bupleurum based formulas and Yueju Pill should be flexibly applied to promote Qi circulation and relieve depression,combined with acupuncture in order to prevent the deterioration of the disease.[Conclusion]"The pathways of spirit"is the way of heart spirit interaction,and communication and coordination between the heart and other organs.Insufficient control of spirit,obstructed pathways of spirit,and impaired heart-spirit functioning are important pathogenesis for the occurrence and development of coronary heart disease with depression.Based on the theory of"the pathways of spirit",it helps to understand the disease evolution process of coronary heart disease with depression,improve the staged diagnosis and treatment rules and specific prescriptions for coronary heart disease with depression.

Objective:To analyze the iodine nutrition status and its related factors among adults aged 18 years and above in Zhejiang Province in 2022.Methods:A multistage stratified sampling method was used to select 4 320 adults aged 18 years and above from 16 on-site survey sites in Zhejiang Province for the study. A questionnaire was used to investigate the general demographic information and personal dietary characteristics of the study participants. Household edible salt and urine samples were collected to detect salt iodine content and urinary iodine level by using direct titration and cerium arsenate-catalyzed spectrophotometry, respectively, to evaluate the iodine nutritional status according to the standard. The multiple-ordered logistic regression model was used to analyze the factors influencing the urinary iodine concentration.Results:The age of the 4 320 study participants was (51.19±15.33) years, with males accounting for 44.44% (1 920). About 40.16% of adults (1 735) were from coastal areas and 56.37% (2 435) from urban areas. The salt iodine content, M ( Q1, Q3), of the 4 320 household edible salt samples was 21.10 (0.00, 24.16) mg/kg, including 1 662 non-iodized salt samples, 182 unqualified iodized salt samples and 2 476 qualified iodized salt samples. The rate of iodized salt coverage was 61.53%, and the rate of qualified iodized salt consumption was 57.31%. There was a statistically significant difference in the proportion of qualified iodized salt in adult households among different regions ( P<0.001), with the proportion of non-iodized salt gradually decreasing from coastal to inland areas ( χ 2trend=618.458, P<0.001). The urinary iodine concentration M ( Q1, Q3) was 137.60 (86.85, 210.60) μg/L in 4 320 adult urine samples, with the urinary iodine levels of<100, 100-199, 200-299, and≥300 μg/L accounting for 31.64% (1 367), 40.56% (1 752), 17.66% (763), and 10.14% (438), respectively. There was a nonlinear positive correlation between household salt iodine content and urinary iodine level in adults aged 18 years and above by using the χ 2 test for trend ( χ 2regression=231.10, P<0.001 and χ 2skew=28.81, P<0.001). Urinary iodine concentrations were higher in men than in women ( P=0.029) and higher in adults in rural areas than in urban areas ( P<0.001). There were statistically significant differences in the distribution of iodine nutritional status among adults of different ages, regions, and urban and rural areas (all P<0.001). The proportion of those with urinary iodine levels<100 μg/L gradually increased with age ( χ 2trend=37.493, P<0.001), and gradually decreased from coastal areas to inland areas ( χ 2trend=71.381, P<0.001). The results of the multiple-ordered logistic regression model analysis showed that compared with adults aged 18 to 44 years and male adults, those aged 45 to 59 years and female adults had lower urinary iodine levels, with OR (95% CI) of 0.75 (0.68-0.83) and 0.85 (0.76-0.95), respectively. Compared with adults in coastal and urban adults, those in sub-coastal, inland and rural adults had higher levels of urinary iodine, with OR (95% CI) of 1.89 (1.63-2.19), 2.02 (1.72-2.37) and 1.46 (1.28-1.66), respectively. Conclusion:The overall iodine nutrition level of adults aged 18 years and above in Zhejiang Province in 2022 is generally appropriate. However, there is a potential risk of iodine deficiency among adults in coastal areas.

Screening carbonyl reductases with the ability to catalyze the reduction of complex carbonyl compounds is of great significance for the biosynthesis of R-tolvaptan(R-TVP). In this study, the target carbonyl reductase in the crude enzyme extract of rabbit liver was separated, purified, and identified by ammonium sulfate precipitation, gel-filtration chromatography, ion exchange chromatography, affinity chromatography, and protein mass spectrometry. With the rabbit liver genome as the template, the gene encoding the carbonyl reductase rlsr5 was amplified by PCR and the recombinant strain was successfully constructed. After RLSR5 was purified by affinity chromatography, its enzymatic properties were characterized. The results indicated that the gene sequence of rlsr5 was 972 bp, encoding a protein with a molecular weight of 40 kDa. RLSR5 was a dimeric protein, and each monomer was composed of a (α/β)₈-barrel structure. RLSR5 could asymmetrically reduce 7-chloro-1-[2-methyl-4-[(2- methylbenzoyl)amino]benzoyl]-5-oxo-2,3,4,5-tetrahydro-1H-1-benzazepine (prochiral ketone, PK) to synthesize R-TVP. The specific activity of the enzyme was 36.64 U/mg, and the optical purity of the product was 99%. This enzyme showcased the optimal performance at pH 6.0 and 30 °C. It was independent of metal ions, with the activity enhanced by Mn²⁺. This study lays a foundation for the biosynthesis of tolvaptan of optical grade.
