This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

OBJECTIVE To systematically evaluate medication risk prediction models for hospitalized adult patients and provide references for their development and clinical application. METHODS Databases including PubMed, Embase, Web of Science, CNKI, Wanfang data, VIP and CBM were searched for studies on medication risk prediction models from their inception to May 2024. After screening the literature, extracting data, and evaluating the quality of the literature, descriptive analysis was performed on the results of the included studies. RESULTS A total of 13 studies were included, involving 12 models. Nine studies used Logistic regression algorithm for modeling, and the number of included predictive factors ranged from 3 to 11; the area under the receiver operating characteristic curve ranged from 0.65 to 0.865. The literature quality evaluation results showed that 10 studies had high risk of bias; 10 studies had high applicability risk. A total of 31 predictive factors were extracted, including 15 items of basic patient information, 3 test indicators, and 5 items of medication information, and 8 others. CONCLUSIONS The existing medication risk prediction models for hospitalized adult inpatients are mainly Logistic regression algorithm, with predictive factors mainly focusing on basic indicators such as demographics. The overall prediction performance of the models needs to be improved, and the overall risk of bias is relatively high.

Osteoporosis is a common bone disease, whose incidence is still on the rise, posing great challenges to patients and society. This review mainly studies the pathogenesis of osteoporosis from the aspects of oxidative stress, inflammatory response, and glucolipotoxicity-induced injury and clarifies the efficacy and mechanism of some active ingredients of traditional Chinese medicine against osteoporosis through the integration of in vitro and in vivo experiments. The experimental results suggest that some active ingredients can improve bone resorption markers and maintain bone homeostasis by modulating inflammation, oxidative stress, etc. These active ingredients regulate osteoporosis through the receptor activator of nuclear transcription factor-κB (NF-κB) ligand (RANKL) pathway, osteoprotegerin (OPG) pathway, Wnt/β-catenin pathway, NF-κB pathway, mitogen-activated protein kinase (MAPK) pathway, adenosine monophosphate (AMP)-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) pathway, and oxidative stress pathway. This review provides ideas for the progress of the prevention and treatment of osteoporosis with the active ingredients of traditional Chinese medicine, aiming to provide new potential lead compounds and reference for the development of innovative drugs and clinical therapy for the treatment of osteoporosis.

ObjectiveTo investigate the role and mechanism of hyodeoxycholic acid (HDCA) in the progression of metabolic associated fatty liver disease (MAFLD), and to provide a new theoretical basis for further clarifying the pathogenesis of MAFLD. MethodsL02 hepatocytes were used as experimental cells, and palmitic acid was used to induce steatosis in L02 cells. The farnesoid X receptor (FXR) siRNA interference chain technique was used to construct a hepatocyte cell line with low FXR expression. CCK8 assay was used to observe the effect of HDCA on L02 steatosis hepatocytes at different concentrations (0, 100, 200, 300, and 400 μmol/L) and time points (12, 24, 36, and 48 hours). The method of qRT-PCR was used to measure the mRNA expression levels of FXR, proliferating cell nuclear antigen (PCNA), Cyclin D1, phosphatidylinositol 3-kinase (PI3K), and protein kinase-B (AKT), and Western blot was used to measure the protein expression levels of FXR, Cyclin D1, PCNA, PI3K, phosphorylated PI3K (p-PI3K), AKT, and phosphorylated (p-AKT). A one-way analysis of variance was used for comparison of normally distributed continuous data with homogeneity of variance between multiple groups, and the Tukey HSD test was used for further comparison between two groups; the Welch analysis of variance was used for comparison of normally distributed continuous data with heterogeneity of variance between multiple groups, and the Games-Howell test was used for further comparison between two groups. The independent-samples t test was used for comparison between two groups. ResultsCCK8 assay showed a significant reduction in the viability of L02 cells and steatosis hepatocytes treated by 300 μmol/L HDCA (P<0.05), and qRT-PCR showed a significant increase in the mRNA expression level of FXR and significant reductions in the mRNA expression levels of PCNA, Cyclin D1, PI3K, and AKT (all P<0.05). Western blot showed a significant increase in the protein expression level of FRX (P<0.05), and after interference of FXR expression in L02 cells, there were significant increases in the protein expression levels of PCNA, PI3K, p-PI3K, AKT, and p-AKT (all P<0.05). ConclusionHDCA inhibits the PI3K/AKT signaling pathway by upregulating FXR expression, thereby inducing a reduction in the viability of steatosis hepatocytes.

Objective:
To understand the status and related knowledge requirements of health emergency literacy among college students in Shaanxi Province, so as to provide the basis for improving college students health emergency literacy.
Methods:
A total of 2 723 students from 18 colleges and universities in Shaanxi Province were selected by multi stage random sampling and simple random sampling methods in November 2023, and the survey of health literacy in emergency and knowledge requirements of health emergency literacy was conducted. Statistical analysis was carried out by using χ 2 test, Wilcoxon rank sum test, Kruskal-Wallis H test and Logistic regression analysis.
Results:
About 28.98% of the surveyed college students had a high level of health emergency literacy, which varied by students whether being only one child, whether having left behind experience, with different personality types, whether being student cadres, and with different frequencies of community or social activities ( χ 2=9.15, 7.90, 32.73, 16.29 , 120.25, P <0.05). The equivalence scores of the four dimensions of health emergency literacy from high to low were poisoning and nuclear and radiation (0.84), medical rescue (0.83), infectious disease (0.82), and basic knowledge and behavior ( 0.77 ). Logistic regression analysis found that college students with left-behind experience were negatively correlated with health emergency literacy and its four dimensions ( OR =0.74, 0.72, 0.80, 0.80, 0.83), while personality type (rational type), community or social activity frequency were positively correlated with the cognitive levels of health emergency literacy and its four dimensions among college students ( OR =1.57, 1.50, 1.33, 1.27, 1.38)( P <0.05). There was a higher level of basic knowledge and behavioral cognition among only child college students ( OR =3.73), and female students had a higher level of health emergency literacy, as well as awareness of infectious disease outbreaks and medical rescue ( OR =1.21, 1.28, 1.21)( P <0.05). The radar map showed that the level of health emergency literacy was positive development radar map. About 67.68 % of the students had a high willingness to acquire health emergency literacy knowledge, and the demand for basic health emergency knowledge and behavioral knowledge was the highest (52.37%).
Conclusions
College students have insufficient health emergency literacy, but they have the highest demand for health emergency. Publicity and education should be strengthened for students with left behind experience, irrational type, and low frequency of community or social activities.
