Nonalcoholic fatty liver disease（NAFLD） is the most common chronic liver disease in the world. Because of its complex pathogenesis， high clinical prevalence and large population， it poses a great threat and challenge to public health in the world. Therefore， active intervention measures are needed. Currently， western medicine is effective in reducing weight， reducing liver fat content， improving glucose-lipid metabolism and insulin resistance. However， for patients with NAFLD-related fibrosis and cirrhosis， there is still a lack of sufficient histological evidence to support its benefits， and randomized controlled trials are still needed to clarify. Lifestyle intervention is an important cornerstone for the treatment of NAFLD， but there are many problems such as poor implementation and low compliance of patients， and the clinical efficacy is not ideal. Traditional Chinese medicine（TCM） has the significant advantages of multiple pathways and multiple targets. Berberine， the active ingredient of TCM， can interfere with the production of NAFLD from multiple pathways， including increasing energy consumption， weight loss， improving glucose-lipid metabolism， improving insulin resistance， anti-inflammatory， anti-oxidation， regulating intestinal flora， restoring bile acid homeostasis， anti-fibrosis and so on， which can play a positive role in the treatment of NAFLD. At the same time， it was found that the combination of BBR with Chinese and western medicines had significant advantages in promoting drug absorption， improving oral bioavailability， increasing the highest biological distribution in the liver， enhancing the overall therapeutic effect of NAFLD， and reducing adverse drug reactions， which could provide reference for clinical medication.

ObjectiveTo investigate the association between serum creatinine/cystatin C ratio （CCR） and nonalcoholic fatty liver disease （NAFLD） based on the NHANES database， and to evaluate the potential significance of CCR as an indicator reflecting the metabolic status of the body. MethodsBased on the data from the NHANES database in 1999‍ ‍—‍ ‍2004， a total of 4 217 participants were enrolled and divided into NAFLD group with 1 726 participants and non-NAFLD group with 2 491 participants. CCR was compared between the two groups， and the association between CCR and NAFLD was analyzed. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. The multivariate logistic regression model was used to investigate the association between CCR and NAFLD； CCR was divided into 4 groups based on quartiles， and odds ratio （OR） and 95% confidence interval （CI） in the regression model was calculated with the first quartile as reference. In addition， the restricted cubic spline analysis was used to investigate whether there was a non-linear relationship between CCR and NAFLD， and interaction items were introduced into the Logistic regression model to perform an interaction analysis. Subgroup analyses were performed based on the stratification of variables to investigate the difference in the association between CCR and NAFLD in different populations. ResultsThe non-NAFLD group had a significantly higher CCR than the NAFLD group （Z=-4.76，P<0.01）. The Logistic regression analysis showed that in model 1 without adjustment of variables， CCR was negatively associated with NAFLD （OR=0.993，95%CI：0.989‍ ‍—‍ ‍0.996，P<0.01）， and in model 3 with adjustment of all variables， CCR was still negatively associated with NAFLD （OR=0.986，95%CI：0.981‍ ‍—‍ ‍0.991，P<0.01）. The analysis of CCR based on quartiles showed a significant association between the increase in CCR and the reduction in the risk of NAFLD. In model 3， compared with the individuals with the lowest quartile of CCR， the individuals with the highest quartile of CCR had a significantly lower risk of NAFLD （OR=0.426，95%CI：0.316‍ ‍—‍ ‍0.574，P<0.01）. Further interaction and subgroup analyses showed that the interaction between CCR and age/sex had a statistical significance （P_interaction<0.01 and P_interaction=0.04）. The subgroup analysis based on age showed a more significant association between CCR and NAFLD in the middle-aged population （≤60 years） （OR=0.982，95%CI：0.976‍ ‍—‍ ‍0.987）， and the subgroup analysis based on sex showed a stronger association between CCR and NAFLD in women （OR=0.979，95%CI：0.972‍ ‍—‍ ‍0.986）. ConclusionThis study shows a significant negative association between CCR and NAFLD， and such association is more significant in middle-aged individuals and women.

MethodsA total of 82 patients with NASH and dyslipidemia from the Gastroenterology Department of the First Affiliated Hospital of Henan University of Chinese Medicine were randomly divided into a control group and a treatment group， with 41 patients in each group. The control group received Polyene Polyenylphosphatidylcholine Capsules， while the treatment group received Dizhuo Huayu prescription granules combined with catgut embedding. The treatment duration was 24 weeks for both groups. At weeks 0， 12， and 24， the traditional Chinese medicine （TCM） syndrome score， body mass index （BMI）， liver fat content assessed by Fibroscan （CAP value）， the level of alanine transaminase （ALT）， aspartate aminotransferase （AST）， gamma-glutamyl transferase （GGT）， total cholesterol （TC）， triglyceride （TG）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， and free fatty acid （FFA）， and the expression of inflammatory cytokines IL-18 and IL-1β in serum were observed. Adverse reactions in both groups were recorded. ResultsA comparison of the comprehensive therapeutic effects between the two groups after 24 weeks of treatment revealed that the total effective rate was 62.16% （23/37） in the control group and 85.71% （30/35） in the treatment group， with a statistically significant difference （χ² = 5.14， P<0.05）. At weeks 12 and 24 after treatment， the TCM syndrome score， BMI， CAP value， TC， TG， LDL-C， and FFA were all significantly lower in both groups compared to pre-treatment levels， while the HDL-C level significantly increased （P<0.05）. The effect was better at week 24 （P<0.05） than at week 12 （P<0.05）， and the treatment group showed better outcomes than the control group at weeks 12 and 24 after treatment （P<0.05）. After 24 weeks of treatment， both groups exhibited significant reductions in IL-18 and IL-1β levels （P<0.05）. The treatment group demonstrated superior efficacy compared to the control group after treatment （P<0.05）. Both groups experienced decreases in ALT， AST， and GGT levels after treatment （P<0.05）. However， there were no statistically significant differences between the 12-week and 24-week post-treatment values within each group， nor were there significant differences between the two groups. No significant adverse reactions were observed in both groups. ConclusionThe Dizhuo Huayu prescription combined with catgut embedding therapy is safe and effective in treating patients with NASH and dyslipidemia， exhibiting hepatoprotective， anti-inflammatory， lipid-regulating， and weight-reducing effects.

ObjectiveTo investigate the role and mechanism of action of paeoniflorin （PF） in protecting HepG2 cells induced by palmitic acid （PA）. MethodsHepG2 cells were stimulated with PA at a concentration of 250 μmol/L to establish a NAFLD model. Compound C at a concentration of 10 μmol/L was used as an inhibitor， and PF at a concentration of 25 μmol/L was used for intervention. The experiment was divided into normal group （CON group） treated with complete culture medium， model group （MOD group） treated with PA， PF treatment group （MOD+PF group） treated with PA and PF， model+inhibitor group （MOD+COM group） treated with PA and Compound C， and model+inhibitor+PF group （MOD+COM+PF group） treated with PA， Compound C， and PF. Kits were used to measure lipid deposition indicators， liver function parameters， oxidative stress indicators， and inflammation indicators； oil red O staining was used to observe lipid deposition； Western Blot was used to measure the protein expression levels of AMPK， SIRT1， PGC-1α， mTOR， Beclin-1， LC3， and P62 in cells. The one-way analysis of variance was used for comparison of quantitative data between groups， while the Tukey’s test was used for comparison between two groups. ResultsCompared with the MOD group， PF improved the levels of TC and TG （P<0.05）， reduced the levels of ALT， AST， CRP， TNF-α， IL-1β， and IL-6 （P<0.05）， increased the activity of SOD and CAT and the level of GSH， and reduced the level of MDA in cells （all P<0.05）. Oil red O staining showed that PF alleviated lipid deposition in cells. Western blot results showed that compared with the MOD group， PF increased the protein expression levels of p-AMPK， SIRT1， PGC-1α， LC3Ⅱ/LC3Ⅰ， and Beclin-1 and reduced the protein expression levels of p-mTOR and P62 （all P<0.05）. ConclusionPF can inhibit PA-induced oxidative stress and inflammatory response in HepG2 cells， improve lipid deposition， and promote autophagy via the AMPK/SIRT1/PGC-1α/mTOR signaling pathway.

Objective: To investigate the spatio-temporal clustering characteristics of influenza in Ningxia Hui Autonomous Region from 2014 to 2023, so as to provide the basis for strengthening influenza prevention and control. Methods: Data pertaining to influenza cases reported in Ningxia Hui Autonomous Region from 2014 to 2023 were retrieved from the Infectious Disease Surveillance System of the Chinese Disease Prevention and Control Information System, including age, sex, current residence, onset date, and reporting date. The seasonal incidence of influenza was analyzed using seasonal index. The spatio-temporal clustering characteristics of influenza were identified using spatial autocorrelation analysis and spatio-temporal scan analysis. Results: A total of 20 377 influenza cases were reported in Ningxia Hui Autonomous Region from 2014 to 2023, with a male-to-female ratio of 1.15∶1. The majority were children under 15 years, with 10 950 cases accounting for 53.74%. Influenza was highly prevalent in January, February, March, and December, with seasonal indices of 219.06%, 111.00%, 246.65%, and 366.24%, respectively. The average annual reported incidence was 29.55/100 000, among which Pengyang County, Jinfeng District, Dawukou District, Xiji County, and Litong District had higher average annual reported incidence, at 63.99/100 000, 55.71/100 000, 55.70/100 000, 49.49/100 000, and 49.04/100 000, respectively. Spatial autocorrelation analysis showed that in 2023, there was spatial clustering of influenza cases in Ningxia Hui Autonomous Region (Moran's I=0.333, P<0.05), with a high-high cluster in Jingyuan County, while in other years, the distribution of influenza cases was random (all P>0.05). Spatio-temporal scan analysis showed that from 2014 to 2023, there were four space-time clusters in Ningxia Hui Autonomous Region, including one type Ⅰ cluster in Hongsibao District of Wuzhong City, with the clustering period from January 20 to 26, 2014; and three type Ⅱ clusters, mainly in January, February, March and December, covering one area in Shizuishan City, five areas in Guyuan City, one area in Zhongwei City, three areas in Wuzhong City, and four areas in Yinchuan City. Conclusions From 2014 to 2023, children under 15 years were the primary population affected by influenza in Ningxia Hui Autonomous Region, with distinct spatio-temporal distribution characteristics. The peak incidence occurred during the winter and spring seasons, and the main clustering areas were in the southern regions.

Objective　To explore the characteristics of toxic heavy metal pollution in atmospheric PM2.5 (Particulate matter 2.5) during winter in Nanning City and to evaluate the health risks for the population. Methods　Atmospheric PM2.5 samples were continuously collected in the urban areas of Nanning from January to February 2019. The concentrations of seven toxic heavy metals, including cadmium (Cd), arsenic (As), chromium (Cr), lead (Pb), nickel (Ni), mercury (Hg), and manganese (Mn) in atmospheric PM2.5 were analyzed by X-ray fluorescence spectrometry. The pollution characteristics of toxic heavy metals were studied by geo-accumulation index and enrichment factor methods, and their health risks to children and adults were assessed using the health risk assessment model of the United States Environmental Protection Agency. Results　The mass concentration of atmospheric PM2.5 in Nanning in winter 2019 was (44±29) μg/m3, which was generally at a low level. Different degrees of pollution were found for Hg, Cd, As, Cr, and Pb in PM2.5, with Hg and Cd being more seriously polluted. Hg and Cd were highly enriched in PM2.5, followed by Pb with moderate enrichment. These three elements mainly originated from man-made pollution. As, Cr and Ni were mildly enriched and affected by both natural and anthropogenic sources. The non-carcinogenic risks were in the order of As>Pb>Hg>Cr>Cd>Mn>Ni. The total non-carcinogenic risks for the three populations were all less than 1, which is within acceptable limits. The carcinogenic risks were ranked as Cr>As>Cd>Ni, with Cr, As, and Cd posing carcinogenic risks to children and adults ranging from 1×10-6 to 1×10-4. Moreover, the total carcinogenic risks of heavy metals (Cr, As, Cd, and Ni) were higher than 1×10-4 for children, indicating a potential carcinogenic risk. Conclusions　The mass concentration of PM2.5 and heavy metal elements in Nanning City during the winter of 2019 was relatively low, but the pollution of heavy metals still exists. The non-carcinogenic risk of heavy metals is within an acceptable range, but the carcinogenic risk poses a potential danger to children.
