Objective To evaluate the reporting quality and influencing factors of patient-reported outcome (PRO) data in randomized controlled trials (RCTs) of lung cancer. Methods RCTs of lung cancer with PRO as either primary or secondary endpoints were searched from PubMed, EMbase, Medline, CNKI, Wanfang Data, and VIP databases between January 1, 2010 and April 20, 2024. Reporting quality of included RCTs were assessed based on the CONSORT-PRO extension. Descriptive statistics and bivariate regression analysis were used to describe the reporting quality and analyze the factors influencing the reporting quality. Results A total of 740 articles were retrieved. After screening, 53 eligible RCTs of lung cancer with 22 780 patients were included. The patients were mainly with non-small cell lung cancer (84.91%), with the median sample size of the included studies was 364.0 (160.5, 599.5) patients. The primary PRO tool used was the EORTC QLQ-C30 (60.38%). There were 52 (98.11%) studies whose PRO measured the domain of "symptom management of cough, dyspnea, fatigue, pain, etc.", and 45 (84.91%) studies measured "health-related quality of life". Multicenter studies accounted for 84.91%, and randomized non-blind trials accounted for 62.26%. PRO was used as the primary endpoint in 33.96% of the studies and as secondary endpoints in 66.04%. The reliability and validity of the PRO tools were explicitly mentioned in 11.32% and 7.55% of the studies, respectively. The average completeness of reporting according to the CONSORT-PRO guidelines was 60.00%, ranging from 25.00% to 93.00%. The main factors affecting the completeness of CONSORT-PRO reporting included sample size and publication year. For every increment in sample size, the completeness of reporting increased by 27.5% (SE=0.00, t=2.040, P=0.046). Additionally, studies published after 2018 had a 67.2% higher completeness of reporting compared to those published in or before 2018 (SE=17.8, t=–3.273, P=0.006). Conclusion The study reveals that the overall reporting quality of PRO in lung cancer RCTs is poor. Particularly, the reporting of PRO measures reliability and validity, PRO assumptions, applicability, and handling of missing data need further improvement. Future research should emphasize comprehensive adherence to the CONSORT-PRO guidelines.

With the continuous intensification of aging, chronic diseases among the elderly have become a widely concerned public health issue. In the terminal stage, they often lose the ability to express their medical care wishes autonomously, leading to a disconnect between medical decision-making and the actual needs of the patients and increasing their physical and psychological suffering. With the rapid aging process in China, the incidence of chronic diseases in the elderly is continuously rising, which has become a serious public health problem. Studies have shown that advance care planning (ACP) has achieved remarkable results in maintaining the dignity of life for terminal chronic disease patients, improving patients’ quality of life, as well as alleviating the physical, mental, and economic burdens on their families. Therefore, the implementation of ACP is crucial for elderly patients with chronic diseases. This paper reviewed the concept of ACP, as well as application effects, challenges and limitations, and corresponding recommendations and countermeasures of ACP in elderly patients with chronic diseases, with a view to providing a solid theoretical and practical basis for the application of ACP in elderly population with chronic diseases in China.

ObjectiveTo investigate the potential mechanisms of Zingiberis Rhizoma in treating inflammatory bowel disease (IBD) by integrating network pharmacology with in vitro and in vivo experiments. MethodsTraditional Chinese Medicine Systems Pharmacology Database And Analysis Platform (TCMSP), Traditional Chinese Medicine Integrated Database (TCMID) Database were used to obtain the active component targets of Zingiberis Rhizoma. GeneCards was used to obtain the IBD targets. DAVID was used to perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses on core targets. Cytoscape 3.10.2 was used to establish the "active component-disease target-signaling pathway" interaction network. Mice were randomly assigned to control, model, and Zingiberis Rhizoma (400 mg·kg-1) groups. An IBD model was induced via dextran sulfate sodium (DSS). The colonic tissue was collected post-treatment to assess histology, expression of Ly6C+ monocytes/macrophages, and mRNA levels of Toll-like receptor 4 (TLR4), and inflammatory cytokines. The effect of Zingiberis Rhizoma aqueous extract on RAW264.7 cell viability was evaluated. Furthermore, the effects of the extract at 100, 10, and 1 mg·L-1 on LPS-induced differentiation of RAW264.7 cells into Ly6Chi monocytes/macrophages, mRNA levels of TLR4 and inflammatory cytokines, and protein levels of factors in the TLR4/mitogen-activated protein kinase (MAPK) signaling pathway. ResultsA total of 241 targets were identified for Zingiberis Rhizoma and 6 787 for IBD, with 122 shared targets among Zingiberis Rhizoma, ulcerative colitis (UC), and Crohn's disease (CD). The enrichment analyses yielded 297 GO terms and 88 KEGG pathways. Associations were noted between Zingiberis Rhizoma's active component targets and IBD targets. In vivo experiments: Compared with the control group, the model group showed decreased body weight and disease activity index (DAI)(P<0.01), shortened colon length, damaged mucosal epithelium with inflammatory cell infiltration, raised pathological scores (P<0.05), increased Ly6Chi and Ly6Clo monocytes/macrophages (P<0.05), and up-regulated mRNA levels of TLR4, TNF-α, IL-1β, and IL-6 (P<0.05) and protein levels of TLR4, phosphorylated extracellular signal-regulated protein kinase 1/2 (p-ERK1/2), and phosphorylated p38 MAPK (p-p38 MAPK) (P<0.05). Zingiberis Rhizoma intervention reversed these changes and reduced Ly6Chi monocytes/macrophages (P<0.01). In vitro experiments: compared with the control, LPS increased the proportion and number of Ly6Chi monocytes/macrophages and mRNA levels of TLR4, TNF-α, IL-1β, and IL-6 (P<0.01) and enhanced the expression of TLR4, p-ERK1/2, and p-p38 MAPK (P<0.05). Zingiberis Rhizoma reduced Ly6Chi monocytes/macrophages (P<0.05), down-regulated the mRNA levels of inflammatory cytokines (P<0.05), and suppressed the TLR4/MAPK pathway (P<0.05). ConclusionZingiberis Rhizoma alleviates IBD by suppressing the TLR4/ERK/p38 MAPK signaling pathway and reducing inflammatory cytokine levels in Ly6Chi monocytes/macrophages.

ObjectiveTo clarify the repair effect of Mume Fructus on the intestinal mucosal epithelial barrier in the mouse model of inflammatory bowel disease (IBD) and explore the repair mechanism. MethodsThirty-six male C57BL/6 mice were randomly assigned into six groups: normal, model, low-, medium-, and high-dose (200, 400, and 800 mg·kg-1) Mume Fructus, and sulfasalazine (300 mg·kg-1). Except the normal group, the rest groups had free access to 2% dextran sulfate sodium (DSS) solution for seven days to establish the IBD model, followed by a seven-day drug intervention. The body weight change and disease activity index (DAI) were recorded. After the last administration, spleen and colon tissue samples were collected to analyze the differences in colon length and spleen index. Hematoxylin-eosin staining was used to observe the morphology of the colon tissue. The level of diamine oxidase (DAO) in the serum was measured by the DAO assay kit. Immunohistochemistry was employed to determine the expression of tight junction proteins such as Claudin-1, Occludin, and zonula occludens-1 (ZO-1) in the colon tissue. Real-time PCR was performed to measure the mRNA levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the colon tissue. Finally, Western blot was employed to determine the protein levels of mitogen-activated protein kinase kinase (MEK), extracellular signal-regulated kinase (ERK), phosphorylated (p)-MEK, and phosphorylated ERK in the colon tissue. ResultsCompared with the normal group, the model group exhibited decreases in body weight and colon length (P<0.01), increases in DAI, spleen index, and serum DAO level (P<0.01), damaged colonic epithelium and goblet cells, and obvious infiltration of inflammatory cells. In addition, the model group exhibited higher positive expression of Claudin-1, Occludin, and ZO-1 (P<0.01), higher mRNA levels of TNF-α and IL-1β (P<0.01), and higher protein levels of p-MEK and p-ERK (P<0.05, P<0.01) than the normal group. However, sulfasalazine and three doses of Mume Fructus markedly decreased the body weight and DAI (P<0.05), recovered the colon length and spleen index, alleviated colon tissue damage, lowered the level of DAO in the serum (P<0.01), and down-regulated the mRNA levels of TNF-α and IL-1β (P<0.01) and the protein levels of p-MEK and p-ERK (P<0.05). Sulfasalazine and low- and medium-dose Mume Fructus increased the positive expression of Occludin, Claudin-1, and ZO-1 (P<0.05, P<0.01). Furthermore, high-dose Mume Fructus elevated the protein expression of Occludin (P<0.05). ConclusionMume Fructus can restore the expression of intestinal epithelial tight junction proteins by inhibiting the phosphorylation of proteins in the MEK/ERK signaling pathway and down-regulating the levels of TNF-α and IL-1β, thus repairing the intestinal mucosal barrier in the mouse model of IBD.

ObjectiveTo investigate the modulating effect of modified Wumeiwan (MWMW) on the ulcerative colitis (UC)-associated intestinal helper T cell 17 (Th17)/regulatory T cell (Treg) balance and intestinal flora by using a human flora-associated model of UC patients with dampness-heat obstruction syndrome, thus providing a new idea for the UC-related research and therapeutic strategies. MethodsThe 24 male C57BL/6J mice were randomized into normal control, model, and MWMW groups (n=8). Model and MWMW groups were first treated with an antibiotic cocktail (vancomycin, 0.1 g·kg-1; neomycin sulfate, 0.2 g·kg-1; ampicillin, 0.2 g·kg-1; metronidazole, 0.2 g·kg-1) for 21 days. At the end of antibiotic treatment, the gavage of fecal microbiota suspension from UC patients with dampness-heat obstruction syndrome was started at a dose of 0.2 mL·d-1 for 19 consecutive days, by which a human flora-associated model of UC was obtained. The MWMW group was administrated daily with MWMW liquid (12.5 g·kg-1), while the normal control and model groups were administrated by gavage with an equal amount of sterile water for 7 consecutive days. The symptoms of dampness-heat obstruction were observed. The colon length and spleen index were measured and calculated, and the proportions of Th17 and Treg cells were detected by flow assay. The intestinal flora was analyzed by 16S rRNA high-throughput sequencing. ResultsCompared with the normal control group, the model group showed shortened colon (P<0.05) and increased spleen index (P<0.01). Compared with the model group, the MWMW group showed prolonged colon (P<0.01) and decreased spleen index (P<0.05). After the intervention of MWMW, the Th17 proportion and Th17/Treg ratio in the colon decreased (P<0.01), and the proportion of Treg cells increased (P<0.05). The number of species and alpha and beta diversity of intestinal flora in mice were regulated by MWMW (P<0.05). In terms of intestinal flora composition, MWMW increased the relative abundance of several phyla (Firmicutes, Proteobacteria, Fusobacteriota, Actinobacteriota, and Gemmatimonadota), the genus Bacteroides, and two species (Bacteroides thetaiotaomicron and B. fragilis) in model mice. Moreover, Spearman's correlation analysis showed that the relative abundance of B. thetaiotaomicron and B. fragilis were negatively correlated with the Th17 level (P<0.05). In addition, the above changes in intestinal flora caused the changes in microbial genes involved in 14 pathways, such as glycolysis, amino acid degradation, inorganic nutrient metabolism, biosynthesis of pyrimidine deoxyribonucleotides, antibiotic resistance, and degradation of polysaccharides. ConclusionsThe human flora-associated model successfully simulated the changes (marked by a decrease in the abundance of Bacteroides) of intestinal flora in UC patients with dampness-heat obstruction syndrome. MWMW can enrich the abundance of beneficial bacteria such as B. thetaiotaomicron and B. fragilis and promote the synergistic intestinal immune modulation with the metabolic functions centered on glycolysis, amino acid metabolism, and nucleotide synthesis through bacterial polysaccharide utilization sites to reduce the Th17/Treg ratio, thereby exerting a protective effect on UC.

ObjectiveTo explore the evolution of medication patterns and syndrome-herb associations of traditional Chinese medicine (TCM) in treating inflammatory bowel disease (IBD), providing a theoretical foundation for precise syndrome differentiation and treatment in clinical practice. MethodsMedical case literature on TCM treatment of IBD from 1960 to 2024 was retrieved to establish a database. Frequency statistics, cluster analysis, change point detection, and association rule mining were employed to comprehensively analyze the syndrome distribution, therapeutic methods, medication patterns, and their temporal variations. ResultsA total of 685 medical cases were included. Common syndromes were dampness-heat (66.42%) and spleen deficiency (56.20%). Primary therapeutic methods included heat clearing (63.65%), spleen invigorating (47.45%), and dampness draining (36.79%). High-frequency herbs included Coptidis Rhizoma (354), Paeoniae Radix Alba (303), Aucklandiae Radix (292), Codonopsis Radix (253), and Glycyrrhizae Radix et Rhizoma (244). Initial prescription clustering revealed three core therapeutic method combinations: heat clearing and detoxifying (represented by Baitouweng Tang), spleen invigorating and Qi reinforcing (represented by Shenling Baizhusan), and cold-heat regulation (represented by Wumeiwan combined with Shaoyao tang). Temporal analysis identified 2008 as a key transition point in TCM treatment of IBD, with significantly increased usage frequency of heat-clearing and dampness-drying herbs such as Fraxini Cortex, Phellodendri Chinensis Cortex, Sophorae Flavescentis Radix, and Scutellariae Radix as well as hemostatic herbs such as carbonized Sanguisorbae Radix, Bletillae Rhizoma, Agrimoniae Herba, and Notoginseng Radix et Rhizoma. Follow-up efficacy analysis showed median improvement rates of 64.0% at the first follow-up, 76.0% at the second follow-up, and 78.7% at the third follow-up. Syndrome-drug association analysis revealed specific herb pairs with significant therapeutic advantages, including Notoginseng Radix et Rhizoma + Coicis Semen, Sanguisorbae Radix + Coptidis Rhizoma, and Codonopsis Radix + Aconii Lateralis Radix Praeparaia. ConclusionTCM medication patterns for treating IBD demonstrate distinct temporal evolution characteristics, with significantly increased usage frequency of herbs such as Fraxini Cortex, Notoginseng Radix et Rhizoma, and Agrimoniae Herba. Significant therapeutic method-herb associations and syndrome-herb association patterns exist, with the formation of specific herb pairs, providing evidence-based support for precise syndrome differentiation and treatment of IBD.

Objective To analyze the abnormal individual dose monitoring results in 206 medical institutions in a selected region in 2024, and to propose improvement measures. Methods Individuals with monitoring results exceeding the investigation level were subjected to high-dose investigation, and the results were statistically analyzed. Results In 2024, the individual dose monitoring of 206 medical institutions in a selected region showed 1.04% abnormal results. The proportions of abnormal results from primary, secondary, and tertiary medical institutions were 12.22%, 3.33%, and 84.45%, respectively. In analysis of the causes of abnormal results, 52.53% of the cases were due to personal dosimeters left in the radiation workplace, and 20.20% were due to the confusion in wearing personal dosimeters inside and outside the lead apron. In analysis of the occupational distribution of the radiation workers with abnormal monitoring results, interventional radiology and diagnostic radiology accounted for 73.34% and 24.44%, respectively. Statistical analysis of the dose range showed that doses in the ranges of 1.25-2.0 mSv and 2.0-5.0 mSv accounted for 42.22% and 33.33%, respectively. In the report of abnormal monitoring results, the proportions of reporting notional dose and reporting measured results accounted for 88.89% and 11.11%, respectively. Among institutions with consecutive abnormal results, primary, secondary, and tertiary medical institutions accounted for 15.39%, 7.69%, and 76.92%, respectively. Conclusion The level of the hospital, occupational type, the perceived importance of the hospital to the management of radiation protection, and the perceived importance and compliance of the radiation workers with the individual dose monitoring are potential causes of abnormal results. It is recommended that employers should enhance radiation protection training for their radiation workers to ensure proper wearing and storage of dosimeters, and progressively improve the standardization and effectiveness of individual dose monitoring practice.

Objective To evaluate the robustness of cardiovascular meta-analysis with use of fragility index. Methods By searching PubMed, EMbase, and Web of Science databases from 2018 to 2022, relevant literature on cardiovascular meta-analysis was systematically collected and the fragility indexes were calculated; Spearman correlation analysis was used to explore the relationship between fragility index and sample size, total number of events, effect size and its confidence interval width. Results A total of 212 meta-analyses from 29 articles were included, with a median fragility index of 11 (5, 25), a median sample size of 10 301 (3 384, 48 330), and a median total number of events of 360 (129, 1 309). Most meta-analyses chose relative risk as the effect measure (179/212), and chose Mantel-Haenszel method (102/212) and random effects model (153/212). The fragility index was positively correlated with the sample size (rs=0.56, P<0.05) and the total number of events (rs=0.61, P<0.05), and negatively correlated with confidence interval width of the effect size (rs=−0.52, P<0.05). No statistically significant results were obtained in the correlation between the fragility index and effect size. Conclusion The fragility indexes of cardiovascular meta-analyses published in comprehensive journals of high impact factors and professional cardiovascular journals are generally low, and therefore lack robustness. Fragility index is suggested to be reported in medical researches, assisting in explaining the P-value.

Objective To compare Hp(3) calibration with a homemade (A) thermoluminescent dosimeter (TLD) and an imported (B) TLD in a standard X-ray RQR radiation field, to explore the different responses of A and B, and to provide foundation for the calibration of Hp(3). Methods A column mode was selected. Hp(3) calibration was performed using A and B in a standard X-ray RQR radiation field in the Secondary Standard Dosimetry Laboratory, National Institute for Radiological Protection, China Center for Disease Control and Prevention. Angle response, energy response, and linear response were calibrated with RQR4 (60 kV), RQR7 (90 kV), and RQR9 (120 kV), respectively. Results In terms of angle response, the calibration results of A were relatively high, while the calibration results of B were relatively low. In terms of energy response, the calibration results showed a similar pattern to angle response. In terms of linear response, the calibration results of both A and B were satisfactory. Conclusion Both A and B can be used for normal calibration of Hp(3) in a standard X-ray RQR radiation field. However, in actual monitoring, attention should be paid to the energy and angle response values of TLDs.

OBJECTIVE To explore the effect of paeoniflorin on glucose metabolism, inflammation and oxidative stress in rats with gestational diabetes mellitus (GDM) and its potential mechanism based on nuclear factor-erythroid 2-related factor 2 (Nrf2)/ heme oxygenase-1 (HO-1)/nicotinamide adenine dinucleotide phosphate:quinone oxidoreductase 1 (NQO1) signaling pathway. METHODS The female rats fed with high fat and high sugar diet and the male rats fed with an ordinary diet were caged, the successfully conceived rats were collected, and streptozotocin was injected intraperitoneally once to induce the GDM model. The successfully modeled rats were randomly divided into the model group, metformin hydrochloride group (200 mg/kg metformin by gavage), paeoniflorin low-, high-dose groups (45, 90 mg/kg paeoniflorin by gavage, respectively), paeoniflorin+ML385 group (90 mg/kg paeoniflorin by gavage and intraperitoneal injection of 30 mg/kg Nrf2 inhibitor ML385), with 12 rats in each group; in addition, another 12 conceived rats fed with an ordinary diet were selected as the control group. The rats in each drug group were given the corresponding drug/normal saline, once a day, for 2 consecutive weeks. Glucose metabolism indexes [fasting blood glucose (FBG), fasting insulin (FINS), insulin resistance index (HOMA-IR)], serum inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor- α (TNF- α)] and renal tissue oxidative stress indexes [superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px)] were detected; the pathological changes of renal tissue were observed, and the protein expressions of Nrf2, HO-1 and NQO1 in renal tissue were detected. RESULTS Compared with the control group, the renal tissue lesions of the model group were obvious, including glomerular atrophy, edema degeneration of renal tubular epithelial cells and a large number of inflammatory cell infiltration; the levels of FBG and FINS, HOMA-IR, the levels of IL-6 and TNF-α in serum, and the level of MDA in renal tissue were significantly increased (P<0.05), while the levels of SOD and GSH-Px and the protein expressions of Nrf2, HO-1 and NQO1 in renal tissue were significantly decreased (P<0.05). Compared with the model group, the renal tissue lesions of rats in paeoniflorin low-dose and high-dose groups were reduced, the above quantitative indexes were significantly improved, and the improvement effect was better in high-dose group (P<0.05), while ML385 could significantly reverse the improvement effect of paeoniflorin on the above indexes (P<0.05). CONCLUSIONS Paeoniflorin can improve the abnormal glucose metabolism, inflammation and oxidative stress damage of renal tissue in GDM rats, which may be related to the activation of Nrf2/HO-1/NOQ1 signaling pathway.
