In July 2024, the National Healthcare Security Administration issued "Notice on Printing and Distributing the 2.0 Edition Grouping Scheme for Diagnosis Related Group(DRG) and Disease-based Payment and Further Advancing Related Work, " marking the official entry of China's DRG payment reform into the 2.0 era. In the 2.0 edition of the DRG grouping scheme, the number of DRGs has increased by six groups, and that of the adjacent DRGs has increased by 33 groups, featuring more scientific and reasonable grouping that aligns better with clinical practice. The National Healthcare Security Administration has also clarified five supporting management mechanisms, including the special case negotiation mechanism, the fund prepayment mechanism, the negotiation and consultation mechanism, the feedback mechanism for opinion collection, and the data disclosure mechanism. These are aimed at optimizing the management of DRG payment reform to ensure a win-win situation for medical institutions, healthcare security departments, and patients. The release of the DRG 2.0 edition provides medical institutions with more refined management tools and a more reasonable paymentmechanism. Medical institutions need to actively embrace this reform, optimize internal management, and improve service quality to achieve cost control and efficiency enhancement, ultimately leading to a win-win situation for patients, healthcare security funds, and medical institutions.

Quercetin (Que) is a flavonoid compound widely distributed in nature with various biological activities.Its anti-inflammatory effect plays a crucial role in many diseases,closely related to its regula-tion of histone post-translational modifications.However,there have been no detailed reports on the anti-inflammatory effects of quercetin regulating histone post-translational modifications.In this study,we first investigated the effect of quercetin on the M1 macrophages polarization.The results showed that quercetin can significantly down-regulate the levels of interleukin-1β(IL-1β) and interleukin-6 (IL-6 ) in M1 macrophages.Next,we used the super stable isotope labeling by amino acids in cell culture (super-SI-LAC) method derived from SILAC technology based on mass spectrometry to systematically analyze the post-translational modification levels of histone in macrophages treated with quercetin.A total of 30 his-tone modification sites were quantified,of which 12 histone lysine acetylation marks were significantly downregulated and 4 lysine methylation sites were upregulated (fold change>1.2,P<0.05),and some sites were verified by Western blot (WB),which was consistent with the mass spectrometry results.In conclusion,a comprehensive analysis of quercetin on regulating macrophage histone modifications in this study provides reliable data references and new insights for studying its anti-inflammatory mechanism.

Objective:To investigate the effects of naringin(NRG)on apoptosis,proliferation,migration and invasion of oral squa-mous cell carcinoma(OSCC)cells.Methods:NRG of 0,5,10,15,20,25 and 30 μmol/L was respectively used to treat OSCC CAL-27 cells,and CCK-8 assay was used to cell vitality.CAL-27 cells were divided into low,medium and high dose NRG groups(NRG-L,NRG-M and NRG-H),Compound C(AMPK inhibitor)group,NRG-H+Compound C group,and control group(NC group,normal cul-ture).Cell proliferation,apoptosis,migration and invasion were detected by CCK-8 assay,EdU staining,flow cytometry,scratch and Tr-answell assays.The expression of aspartate specific cysteine proteinase-3(Caspase-3),proliferating cell nuclear antigen(PCNA),matrix metalloproteinase-2(MMP-2),MMP-9,p-AMPK,sirtuin 1(SIRT1)and acetylated NF-κB p65(Ac-NF-κB p65)was detected by Western blot.Results:5,10 and 20 μmol/L NRG was selected as the low,medium and high dose for the treatment of CAL-27 cells,re-spectively.Compared with NC group,in NRG-L,NRG-M and NRG-H groups EdU positive rate,scratch healing rate,A450 value,num-ber of invasive cells,the protein expression of PCNA,MMP-2,MMP-9 and Ac-NF-κB p65 in CAL-27 cells decreased,the apoptosis rate,and the protein of Caspase-3,p-AMPK,and SIRT1 increased(P＜0.05);in Compound C group EdU positive rate,scratch healing rate,A450 value,the number of invasive cells,the protein expression of PCNA,MMP-2,MMP-9 and Ac-NF-κB p65 in CAL-27 cells in-creased,apoptosis rate and the protein expression of Caspase-3,p-AMPK and SIRT1 decreased(P＜0.05).Compound C reversed the effects of high dose NRG on the proliferation,migration,apoptosis and invasion of CAL-27 cells.Conclusion:The inhibitory effects of NRG on proliferation,migration and invasion of CAL-27 cells and the promotion of apoptosis may be related to activation of AMPK and inhibition of NF-κB pathway.

Objective To explore the relationship between the levels of peroxidoredoxin(PRDX)1 and chromosome 10 deletion phosphatase-tensin homologous gene(PTEN)and liver function and disease activity in patients with autoimmune liver disease.Methods A total of 83 patients with autoimmune liver disease ad-mitted to the hospital from January 2021 to December 2022 were selected as the study objects.According to the disease activity at admission,they were divided into active group(37 cases)and remission group(46 ca-ses).Clinical data and serum PRDX1 and PTEN levels of the two groups were analyzed.At the same time,Child-Pugh classification of liver function was performed,and the patients were grouped.A total of 100 health-y volunteers who underwent physical examination during the same period were selected as the control group.Multivariate Logistic regression was used to analyze the influencing factors of disease activity in patients with autoimmune liver disease,and the evaluation value of serum PRDX1 and PTEN levels on disease activity in pa-tients with autoimmune liver disease after treatment was analyzed by receiver operating characteristic(ROC)curve and area under the curve(AUC).Results Compared with the grade A group,there were no significant differences in serum PRDX1 and PTEN levels in the grade B group(P＞0.05),while serum PRDX1 level was increased and PTEN level was decreased in the grade C group(P＜0.05).Compared with the grade B group,the serum PRDX1 level was increased and PTEN level was decreased in the grade C group(P＜0.05).Com-pared with the control group,there were no significant differences in serum PRDX1 and PTEN levels in the re-mission group(P＞0.05),while the serum PRDX1 level was increased and PTEN level was decreased in the active group(P＜0.05).Compared with the remission group,the level of serum PRDX1 was increased and the level of PTEN was decreased in the active group(P＜0.05).The AUC of serum PRDX1 and PTEN for evalu-ating the disease activity in autoimmune liver disease patients was 0.750 and 0.854,respectively,and the AUC of the combined detection of serum PRDX1 and PTEN was 0.916.The proportion of patients with hepatic dis-comfort and cirrhosis in the active stage group was higher than that in the remission stage group(P＜0.05).Multivariate Logistic stepwise regression analysis results showed that hepatic discomfort(OR=3.487,95％CI:1.534-7.927),cirrhosis(OR=4.289,95％CI:1.744-10.545),PRDX1 ≥5.22 ng/mL(OR=5.068,95％CI:1.951-13.164),PTEN≤0.31 pg/mL(OR=5.387,95％CI:2.099-13.829)were risk factors for disease activity of autoimmune liver disease(P＜0.05).Conclusion The increase of serum PRDX1 level and the decrease of serum PTEN level are closely related to liver function and disease activity in patients with au-toimmune liver disease,and they have certain clinical evaluation value in patients with autoimmune liver dis-ease.

Objective: To analyze the characteristics of human papillomavirus (HPV) infection and the distribution of HPV subtypes in Shijiazhuang, Hebei Province, and to explore the application evaluation of multiple PCR capillary electrophoresis fragment analysis for HPV typing test. Methods: A population-based cross-sectional study was conducted among 434 women (age range 17 to 74 years old, 260 patients and 174 physical examinations) included from May to August 2022 in Hebei General Hospital. HPV typing was detected by multiple PCR-capillary electrophoresis fragment analysis. Using the multiple fluorescence quantitative PCR kit as a reference, Chi-square test was used to analyze the diagnostic effect of multiple PCR-capillary electrophoresis fragment analysis, and the consistency was analyzed by Kappa value. Results: The total HPV infection rate was 45.85%(199/434), including 35.48% (154/434) of high-risk HPV (HR-HPV), 3.92% (17/434) of low-risk HPV (LR-HPV), 6.45% (28/434) of HR-HPV and LR-HPV mixed infection, 27.88% (121/434) of single type HPV and 17.97% (78/434) of multi type HPV. HPV52 (9.68%, 42/434), HPV16 (6.91%, 30/434), and HPV58 (6.91%, 30/434) are common HPV subtypes. The positive rate of physical examination was 45.40% (79/174), which was slightly lower than that of patients 46.15% (120/260), there was no significant difference (χ²=0.024,P>0.05). The highest infection rate in the 17-30 age group was 54.76% (46/84), and there was no statistical difference among the age groups(χ²=4.123,P>0.05). The sensitivity and specificity of multiplex PCR capillary electrophoresis fragment analysis were 92.96% and 94.04%, respectively, and Kappa value was 0.870, with the multiplex fluorescent quantitative PCR as the reference. Conclusion: HPV infection may appear younger, and the positive rate of HR-HPV infection is the highest, with HPV52, 16, 58 as the main infection subtypes. The detection results of multiplex PCR capillary electrophoresis fragment analysis method are highly consistent with those of multiplex fluorescent quantitative PCR method, which is suitable for HPV DNA typing.

Objective: To establish an ultra-sensitive, ultra-fast, visible detection method for Vibrio parahaemolyticus (VP) . Methods: We established a new method for detecting the tdh and trh genes of VP using clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 12a (CRISPR/Cas12a) combined with recombinase polymerase amplification and visual detection (CRISPR/Cas12a-VD). Results: CRISPR/Cas12a-VD accurately detected target DNA at concentrations as low as 10 ^-18 M (single molecule detection) within 30 min without cross-reactivity against other bacteria. When detecting pure cultures of VP, the consistency of results reached 100% compared with real-time PCR. The method accurately analysed pure cultures and spiked shrimp samples at concentrations as low as 10 ² CFU/g. Conclusion The novel CRISPR/Cas12a-VD method for detecting VP performed better than traditional detection methods, such as real-time PCR, and has great potential for preventing the spread of pathogens.

Patients exhibit good tolerance to messenger ribonucleic acid (mRNA) vaccines, and the choice of encoded molecules is flexible and diverse. These vaccines can be engineered to express full-length antigens containing multiple epitopes without major histocompatibility complex (MHC) restriction, are relatively easy to control and can be rapidly mass produced. In 2021, the U.S. Food and Drug Administration (FDA) approved the first mRNA-based coronavirus disease 2019 (COVID-19) vaccine produced by Pfizer and BioNTech, which has generated enthusiasm for mRNA vaccine research and development. Based on the above characteristics and the development of mRNA vaccines, mRNA cancer vaccines have become a research hotspot and have undergone rapid development, especially in the last five years. This review analyzes the advances in mRNA cancer vaccines from various perspectives, including the selection and expression of antigens/targets, the application of vectors and adjuvants, different administration routes, and preclinical evaluation, to reflect the trends and challenges associated with these vaccines.
