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 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.

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.

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.

The levels of serum CA125, carcinoembryonic antigen and neuron-specific enolase (NSE) were not significantly different between the two groups before treatment ( P>0.05), but after treatment the levels of serum CA125, carcinoembryonic antigen and NSE were decreased in both groups, after treatment, the levels of CD3 + and CD4 + in the observation group were higher than those in the control group ( P<0.001), but the levels of CD3 + and CD4 + in the observation group were higher than those in the control group ( P<0.05), the level of CD8 + in the observation group was significantly lower than that in the control group ( P<0.001), and the level of serum inflammatory factors had no significant difference between the two groups before treatment ( P>0.05), the 2-year mortality rate in the observation group was 59.37% (19.32), which was significantly lower than that in the control group (81.25%, 26/32)( P=0.015). There was no significant difference in the incidence of adverse reactions between the two groups ( P=0.768). Conclusion:PD-1 inhibitor in combination with paclitaxel and platinum is a potential treatment for advanced non-small-cell lung carcinoma non-small cell lung cancer (NSCLC).

OBJECTIVE To establish a mouse model of diabetes mellitus(DM)combined with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection to investigate the important pathophysiological changes in the development of DM combined with SARS-CoV-2 infection.METHODS Wild-type(WT)mice and transgenic mice expressing the human angiotensin-converting enzyme 2 receptor driven by the cytokeratin-18 gene promoter(K18-hACE2)were randomly divided into the control group,DM group,SARS-CoV-2 spike protein(S)infection group and DM combined with S protein infection group,with 10 to 12 mice in each group.All the mice were induced by 10 weeks of high-fat diet combined with 40 mg·kg-1 streptozotocin(STZ)for 3 days by ip,except those in the control group or S protein infection group.The control group was given the same volume of 0.1 mol·L-1 sodium citrate buffer.Mice in the S protein infection group and DM+S protein infection group were additionally given 50 μL mixture of 15 μg SARS-CoV-2 spike protein and 1 g·L-1 polyinosinic-polycytidylic acid(poly[I:C])via intranasal drops,while the control group was given an equal volume of sterile water.The glucose tolerance level and pancreatic islet β cell function of mice were evaluated via oral glucose tolerance test at the 6th week of high-fat feeding and 1 week after the administration of STZ by ip.From the 6th week of high-fat feeding to 2 weeks after the administration of STZ,the random blood glucose and fasting blood glucose of mice were measured by a blood glucose meter.Blood samples were taken from subman-dibular veins of 3 mice in each group at 24,48 and 120 h after S protein infection,and lung tissues were taken after euthanization.The pathological changes of lungs of DM mice before and after S protein infection were observed by HE staining.Except for the DM group,blood samples were collected before S protein infection and at 6,24,48,72 and 120 h after infection.The levels of plasma interleukin 1β(IL-1β),IL-2,IL-6,IL-10,IL-17,interferon gamma-induced protein 10(IP-10),interferon γ(IFN-γ),tumor necrosis factor α(TNF-α),monocyte chemotactic protein-1(MCP-1)and granulocyte-colony stimulating factor(G-CSF)were detected by Luminex.The plasma levels of heparan sulfate(HS)were measured by enzyme-linked immunosorbent assay.The levels of cytokines and HS were correlated with the degree of pathological damage by Spearman correlation analysis.RESULTS STZ and high-fat diet could induce DM-like expression in mice,and the random blood glucose(P<0.01)and fasting blood glucose(P<0.05)after 1 week in the hACE2-DM group were significantly higher than in the WT-DM group,and the degree of islet function damage in hACE2-DM mice was significantly higher than that of WT-DM mice(P<0.05).Compared with the DM group,the DM+S group showed more severe pulmonary pathological changes after S protein infection,accompanied by a large number of inflammatory infiltrations and thickening of lung interstitial.Compared with the control group,the levels of pro-inflammatory cytokines G-CSF,IL-6 and IP-10 in the plasma of the WT-S group were significantly increased at 6 h after S pro-tein infection(P<0.01),and those of pro-inflammatory cytokine IL-17 and anti-inflammatory cytokine IL-10 were significantly increased at 24 h after S protein infection(P<0.05).Compared with the control group,the plasma levels of pro-inflammatory cytokines IL-1β,IL-6,TNF-α,MCP-1,G-CSF and IP-10 in the hACE2-S group were significantly increased at 6 h after S protein infection(P<0.05,P<0.01).IL-17 was significantly increased at 24 h and 6 h after S protein infection in the WT-DM+S group and hACE2-DM+S group,respectively(P<0.01,P<0.05).In the hACE2-DM+S group,IFN-γ and IL-1β were signifi-cantly increased in delay to 48 h(P<0.05,P<0.01),and MCP-1 was significantly increased in delay to 72h(P<0.05).Compared with the control group,the level of HS in the plasma of the WT-S group increased significantly(P<0.05,P<0.01)at 6 h and 24 h after S protein infection,but began to decrease at 48 h.At the same time,compared with the WT-S group,the HS level in the WT-DM+S group was slightly increased at 6 h after infection and decreased at 24 h.Compared with the control group,the HS level in the hACE2-S group was significantly increased at 24 h(P<0.01),as was the case with the WT-S group 24 h,48 h and 120 h after S protein infection.At 6 h,24 h and 48 h after S protein infection,the plasma HS level of the hACE2-DM+S group was significantly increased(P<0.01,P<0.05),and the duration of the increase was longer than in the hACE2-S group.Moreover,the levels of IL-1β,IL-10,MCP-1,IP-10,G-CSF and HS in plasma were positively correlated with the degree of lung dam-age in the DM+S group.CONCLUSION In this study,the mouse model of diabetes combined with SARS-CoV-2 spike protein infection has mimicked part of the pathophysiological features of clinical patients,mainly manifested as blunted immune response and elevated HS levels with longer duration to infection alone.IL-1β,IL-10,MCP-1,IP-10,G-CSF and HS may keep track of the course of disease in patients with diabetes combined with SARS-CoV-2 infection.
