		                        			ObjectiveTo establish a geographical origin identification model for Foeniculi Fructus from Haiyuan, providing a new technical reference for the protection of Haiyuan's geo-authentic medicinal materials and its designation as a national geographical indication agricultural product. MethodsSamples of Foeniculi Fructus were collected from eight producing areas, including Minqin (Gansu), Bozhou (Anhui), Qingdao (Shandong), Dezhou (Shandong), Urumqi (Xinjiang), Nujiang (Yunnan), Gutuo (Inner Mongolia), and Haiyuan (Ningxia). Gas chromatography-ion mobility spectrometry (GC-IMS) was used to detect the volatile organic compounds (VOCs) in samples from these geographic origins. VOCs were qualitatively analyzed through dual matching with the National Institute of Standards and Technology (NIST) mass spectral database and the IMS drift time database. Using the Reporter module and Gallery Plot visualization tools within the LAV analytical platform, VOC fingerprint profiles characterizing geographic origins were constructed. A non-targeted analytical strategy was adopted, and 97 VOCs detected via GC-IMS were subjected to principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) based on their differential distribution patterns to construct an origin identification model for Foeniculi Fructus from Haiyuan region. Key discriminative markers were screened using variable importance in projection (VIP) values greater than 1. ResultsA total of 97 VOCs were identified, including alcohols, aldehydes, ketones, esters, organic acids, terpenoids, ethers, alkenes, and benzenes. The PLS-DA model, based on VOCs data obtained by GC-IMS, effectively distinguished Foeniculi Fructus in Haiyuan region from those of other origins. During cross-validation, the model achieved a prediction parameter (Q2) of 0.976 and a goodness-of-fit parameter (R2) of 0.936, with no overfitting observed in permutation testing. Twelve key flavor markers with VIP > 1 were identified as characteristic indicators of Haiyuan origin. ConclusionA stable and highly predictive origin identification model for Foeniculi Fructus from Haiyuan was successfully established using GC-IMS technology, PLS-DA, and VIP-based marker screening. This model provides a novel technical strategy for accurately distinguishing Foeniculi Fructus in Haiyuan region from other regional varieties and offers new technical support for its protection as a geo-authentic medicinal material and a nationally designated geographical indication agricultural product in China.

		                        			Objective:To investigate the prevalence of Helicobacter pylori infection among family members, and analyze associated risk factors. Methods:The current investigation was a cross-sectional study. The Qinghai region was stratified into urban areas, agricultural areas, and pastoral areas. The urban areas of Xining City, the agricultural areas of Haidong City, and the pastoral areas of Haibei Tibetan Autonomous Prefecture were selected. A total of 396 resident families (1 131 people) who underwent health checkups from 2021 to 2022 in the above areas were included in the survey study. Questionnaires were administered and H. pylori infection was detected using the 13C-urea breath test. Numerical data were expressed as cases and percentages, and the Chi-square test was used to compare differences in H. pylori infection rates in the populations and families in each group. Multifactorial logistic regression was used to analyze risk factors for H. pylori infection, and P<0.05 was considered statistically significant. Results:The prevalence of H. pylori infection in Qinghai province was 52.8% (597/1 131) and the prevalence of H. pylori infection in households was 80.6% (319/396). In H. pylori-positive households with at least 1 infected spouse, 40.4% (36/89) had only 1 infected spouse, and in 59.6% (53/89) both spouses were infected. In analysis of children infected by parents with H. pylori, 20.0% (9/45) of households had fathers and children infected, 48.9% (22/45) had mothers and children infected, and 31.1% (14/45) had both parents and children infected. In univariate analysis there was a statistically significant difference in the overall comparison of H. pylori infection rates among families with different numbers of people living together ( χ2=11.12, P=0.004), and between-group comparisons suggested that H. pylori infection rates were higher in families with 4 or 5 people and more than 5 people living together than in families with 2 or 3 people living together. The H. pylori infection rate was higher in families that did not use serving chopsticks and spoons during family meals than in families that did use serving chopsticks and spoons ( χ2=6.12, P=0.013). In multifactorial logistic regression analyses the number of people living together in a family and whether or not serving chopsticks and spoons were used at family meals were associated with H. pylori infection ( P<0.05). Conclusion:The H. pylori infection rate in families in Qinghai Province is high, and there is a clear association with family aggregation. It is more common for both members of a couple to be infected, and H. pylori infection of a mother has a greater effect on the children′s infection status than H. pylori infection of a father. The infection rate of H. pylori was lower in families that used serving chopsticks and spoons during dinner gatherings, and the fewer the number of people living together in the family, the lower the H. pylori infection rate.

		                        			This article reviews relevant literature on the prevention and treatment of cancer with hesperidin published in the past 10 years by searching electronic databases such as China National Knowledge Infrastructure(CNKI), Wanfang, and PubMed, and summarizes the research progress on the anticancer mechanism of hesperidin. Hesperidin has a wide range of pharmacological effects, including anti-inflammatory, antioxidant, antibacterial, antiviral, anticancer, immune-regulatory, anti-radiation, neuroprotective and cardiovascular protective properties and so on. Its anticancer mechanisms mainly include inhibiting cancer cell proliferation, promoting apoptosis, reducing angiogenesis, inhibiting invasion and migration of cancer cells, regulating immunity and autophagy, and exerting antioxidant and anti-inflammatory effects. As a broad-spectrum anticancer drug, hesperidin manifests chemo-preventive and therapeutic effects across various cancers, contingent upon its multifaceted anticancer mechanisms. Furthermore, this article summarizes the synergistic effects of hesperidin in combination with cisplatin, doxorubicin, cyclophosphamide and paclitaxel. It elucidates that hesperidin can enhance the cytotoxicity of these anticancer drugs against cancer cells while mitigating drug resistance and adverse side effects. Nonetheless, the clinical use is somewhat constrained due to its poor water solubility and limited bioavailability. Therefore, this article also outlines the current strategies for enhancing hesperidin's bioavailability, including structural modification, combination with other chemical substances, and utilization of nano drug carriers.The discovery of derivatives of hesperidin not only preserves the anticancer efficacy of hesperidin, but also effectively overcomes the shortcomings of poor water solubility and low bioavailability of hesperidin, effectively predicting the good application prospects of hesperidin and its derivatives.

		                        			Stomach exuberance and spleen deficiency are common pathogenesis of many metabolic diseases. Through analyzing the pathogenesis of stomach exuberance and spleen deficiency, it is believed that its essence is stomach heat and spleen deficiency. Stomach heat includes gastrointestinal heat, spleen and stomach damp-heat, and spleen deficiency is divided into deficiency of spleen yin, deficiency of spleen qi , and deficiency of spleen yang. It is suggested that the metabolic diseases of stomach-exuberance and spleen-deficiency syndrome can be divided into three categories,i.e. stomach-heat and spleen yin-deficiency, stomach-heat and spleen qi-deficiency, and stomach-heat and spleen yang-deficiency, and the main treatment methods are clearing and draining heat, nourishing yin and moistening intestine, clearing dampness and heat, strengthening spleen and qi, clearing dampness and heat, strengthening spleen and warming yang, respectively, with prescriptions as Maziren Pills (麻子仁丸), Qinlian Pingwei Powder (芩连平胃散), and Jiawei Lianli Decoction (加味连理汤) accordingly.

		                        			Objective:To assess the association between short-term ambient air pollution exposure and arterial stiffness and whether obesity modifies these associations.Methods:A cross-sectional study was conducted based on Fangshan family cohort in Beijing. The 24 hours average air pollutant levels on the day cohort participants took baseline survey were calculated as short-term air pollution. A generalized additive model (GAM) with Gaussian links was used to estimate changes in typical carotid artery intima-media thickness (CIMT), brachial-ankle pulse wave velocity (BAPWV), pulse pressure (PP) and ankle-branchial index (ABI) after short-term exposure to each air pollution (PM 2.5, PM 10, SO 2, NO 2, CO). The cross-product terms of each air pollution, body mass index (BMI), and waist-to-hip ratio were included in the GAM model to test the interaction. Further, they conducted a stratified analysis to test their effects on the relationship between short-term exposure to each air pollution and the arterial stiffness indicators. Results:A total of 4 211 individuals were included in the analysis. Individuals' age was (58.9±8.7) years, of which 2 268 (53.9%) were female. Several covariates, including sociodemographic factors, lifestyle behaviors, and history of drugs, were included in the analysis. The results of the GAM analysis showed that an increase in PM 2.5 ( β=2.912×10 -4, 95% CI: 1.424×10 -4-4.400×10 -4, P<0.001), CO ( β=0.027, 95% CI: 0.011-0.043, P<0.001), SO 2 ( β=2.070×10 -3, 95% CI: 7.060×10 -4-3.430×10 -3, P=0.003), and NO 2 ( β=3.650×10 -4, 95% CI: 2.340×10 -5-7.060×10 -4, P=0.036) were associated with an increase in CIMT, while an increase in PM 10 ( β=0.018, 95% CI: 0.002-0.033, P=0.028) was associated with an increase in PP in the study population. Besides, the waist-to-hip ratio had an effect-modification on the correlation of short-term exposure of PM 2.5 (interaction P=0.015), NO 2 (interaction P=0.008), and CO (interaction P=0.044) with CIMT, and the correlation between short-term exposure of PM 2.5 (interaction P=0.002), NO 2 (interaction P=0.010), CO (interaction P=0.029), PM 10 (interaction P<0.001) with PP. The significant association between CIMT, PP, and air pollution concentrations was more visible in people with lower waist-to-hip ratios. Conclusions:Short-term ambient air pollution exposure was associated with arterial stiffness indicators, and there was an effect modification of waist-to-hip ratio on these associations, and lower waist-to-hip ratios may enhance the association between air pollution exposure and indicators.
