ObjectiveTo investigate the changes in chemical components of Gardeniae Fructus（GF） before and after being charred， providing data support for research on the material basis of GF Carbonisata（GFC）. MethodsUltra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry（UPLC-Q-Orbitrap MS/MS） was used to conduct a comprehensive analysis of the chemical components in GF and GFC under positive and negative ion modes with Compound Discoverer 3.3 software and online database. Then， principal component analysis and partial least squares-discriminant analysis in SIMCA14.1 software were used to analyze the MS data of each sample. Based on the principle of variable importance in the projection（VIP） value>1， differential secondary and primary metabolites before and after carbonization were screened. In addition， MetaboAnalyst website was used for pathway enrichment of Kyoto Encyclopedia of Genes and Genomes（KEGG）， so as to provide a reference for clarifying the processing mechanism. ResultsA total of 185 components were identified， including 96 secondary metabolites and 89 primary metabolites. These components were classified into nine categories， primarily including iridoid glycosides， flavonoids， and terpenoids， their fragmentation pathways were also analyzed. Simultaneously， multivariate statistical analysis was performed on the secondary and primary metabolites， identifying 70 and 59 differential metabolites， respectively. The secondary metabolites were enriched in two metabolic pathways， including C5-branched dibasic acid metabolism and flavonoid and flavonol biosynthesis， while the primary differential metabolites were enriched in seven pathways such as linoleic acid metabolism and tyrosine metabolism. ConclusionThe chemical components of GF change significantly after carbonization， with a significant decrease in the contents of iridoid glycosides and terpenoids such as hydroxyisogeniposide， crocin Ⅱ， crocetin， and jasminoside B. while the contents of 4-hydroxycoumarin， geniposidic acid， gentiopicroside， and gardenoside methyl ester increase significantly. This change is presumed to be associated with the enhanced cooling and hemostatic effects of the processed products. The identified key components provide a basis for elucidating the material basis underlying the efficacy changes before and after carbonization.

BACKGROUND:It has been found that abnormal apoptosis of bone tissue cells induced by abnormal iron metabolism plays an important role in the progression of osteoporosis. OBJECTIVE:To investigate the effect of naringin on iron metabolism and cell apoptosis in bone tissue of rats with osteoporosis. METHODS:Fifty 2-month-old female Sprague-Dawley rats were randomly divided into five groups with 10 rats in each group:sham group,osteoporosis group,naringin low-dose group,naringin high-dose group,and naringin high-dose+DKK-1 group.Except for the sham group,rat models of osteoporosis were established by removing bilateral ovarian tissues in the other groups.At 8 weeks after modeling,rats in the naringin low-and high-dose groups were given 100 and 400 mg/kg/d naringenin by gavage,respectively,and rats in the naringenin high dose+DKK-1 group were given 400 mg/kg/d naringin by gavage and subcutaneous injection of 25 mg/kg/d DKK-1,an inhibitor of the Wnt1 signaling pathway,for 7 consecutive days.Relevant indexes were detected after administration. RESULTS AND CONCLUSION:Compared with the osteoporosis group,naringin could enhance the bone mineral density and serum calcium and superoxide dismutase levels in rats(P<0.05),and reduce the serum levels of osteocalcin,malondialdehyde,and phosphorus(P<0.05),while DKK-1 could partially inhibit the interventional effect of naringin(P<0.05).Results from Micro-CT scanning,hematoxylin-eosin and TUNEL staining showed that compared with the osteoporosis group,naringin significantly improved bone microstructure and reduced the rate of cell apoptosis,while DKK-1 partially inhibited the interventional effect of naringin.Immunofluorescence staining results showed that compared with the osteoporosis group,naringin could reduce the oxygen content,anti-tartaric acid phosphatase expression,and elevate the expression of alkaline phosphatase in active tibia tissues(P<0.05),while DKK-1 could partially inhibit the interventional effect of naringin(P<0.05).Results from Prussian blue staining and immunohistochemical staining showed that compared with the osteoporosis group,naringin reduced iron deposition in bone and liver tissues as well as the expression of transferrin receptor 1(P<0.05),and elevated the protein expression of ferroportin 1(P<0.05)in bone tissue,and DKK-1 partially inhibited the intervention of naringin(P<0.05).PCR and western blot assay of tibia specimens showed that compared with the osteoporosis group,naringin decreased the expression of anti-tartrate acid phosphatase,transferrin receptor 1 and Bax(P<0.05),and elevated the expression of alkaline phosphatase,ferroportin 1,Bcl-2,Wnt1 and β-catenin(P<0.05),while DKK-1 partially inhibited the interfering effect of naringin(P<0.05).To conclude,naringin inhibits the progression of osteoporosis by reducing iron deposition and apoptosis rate in bone tissue,which may be related to the activation of the Wnt1 signaling pathway.

Gastric cancer is one of the most common malignant tumors in the digestive tract, which has the characteristics of high morbidity and mortality. However, gastric cancer is not achieved overnight but is gradually developing through the interaction of many factors. Therefore, actively delaying or blocking the "inflammation-cancer" transformation in gastric mucosa is the key to treatment. Nod-like receptor protein 3(NLRP3) inflammasome is a multi-protein signal complex and one of the important innate immune signal receptors. Inflammation plays an important role in the occurrence and development of gastric cancer, and continuous inflammation mediation will trigger the transformation from inflammation to cancer. Therefore, the significance of NLRP3 inflammasome to gastric mucosa lies in the transformation between inflammation and cancer. Traditional Chinese medicine(TCM) has the functions of multi-components, multi-targets, and few adverse reactions. A large number of studies show that TCM and related monomers have significant effects in treating liver, kidney, and immune diseases through mediating NLRP3 inflammasome, but there is less research on the "inflammation-cancer" transformation in gastric mucosa. By combing the NLRP3-related nuclear factor-κB transcription factor(NF-κB), hypoxia inducible factor-1α(HIF-1α), phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt), and other signal pathways, this paper clarified their mechanisms in the "inflammation-cancer" transformation in gastric mucosa, delayed the process of "inflammation-cancer" transformation in gastric mucosa through four aspects: energy metabolism, pyroptosis, immune response, and vascular endothelial growth factor, and prevented and treated "inflammation-cancer" transformation in gastric mucosa from three aspects: TCM monomer, TCM compound prescription, and other therapies, so as to provide ideas for the subsequent treatment of "inflammation-cancer" transformation in gastric mucosa with TCM.

Objective To analyze and compare the disease burden of high BMI in Kunshan City in different periods, and to provide a scientific basis for the prevention and control of overweight and obesity in Kunshan City. Methods Using the global burden of disease research method, the number of deaths attributable to high BMI and attributable YLL in Kunshan City were calculated using the survey data of chronic diseases and their risk factors and the data of the death registration system in Kunshan City. Results In 2023, R5.46% of deaths in Kunshan City were attributed to high BMI, with 345 attributable deaths, and attributable mortality rate and standardized attributable mortality rate were 39.16/100 000 and 33.82/100 000, Rrespectively. Attributable YLL rate and standardized attributable YLL rate were 692.35/100 000 and 604.46/100 000, respectively. High BMI caused a loss of 0.52 years of life expectancy per capita. Compared with 2012, PAF, standardized attributable mortality rate, standardized attributable YLL rate and life expectancy loss per capita of high BMI in 2023 increased by 121.95%, 100.71%, 57.05%, and 100%, respectively. Among different genders, PAF increased by 91.05% for males and 161.97% for females from 2012 to 2023. Among different diseases, cardiovascular and cerebrovascular diseases and cancers had the highest attributable disease burden, while diabetes, chronic kidney disease and Alzheimer's disease all had a significant increase. Conclusion The burden of disease attributable to high BMI has risen dramatically in Kunshan City, and the adverse health effects of overweight and obesity need to be reduced through scientific weight loss and comprehensive practical measures.

Objective To investigate the early dynamic changes of biomarkers associated with capillary leak syndrome(CLS)in patients with severe acute pancreatitis(SAP)and their correlation with multiple organ failure(MOF).Methods A total of 171 SAP patients admitted to the West China Centre of Excellence for Pancreatitis,West China Hospital,Sichuan University between September 1,2019 and December 31,2020 were enrolled for this study.The patients were divided into MOF and non-MOF groups based on the occurrence of MOF in the first 5 days of hospitalization,and were further divided into subgroups based on the presence of moderate-to-severe intra-abdominal hypertension(IAH).We performed dynamic monitoring of the blood biomarkers(hematocrit[HCT].blood urea nitrogen[BUN].and creatinine[Cr]),plasma proteins(albumin[Alb].total protein[TP].and non-albumin plasma proteins[NAPP]),and intra-abdominal pressure.Trends in these indicators across groups were analyzed comprehensively.Results No significant differences in baseline data between the two groups were observed.The baseline data of the 2 groups were comparable.The MOF group had significantly higher rates of persistent systemic inflammatory response syndrome(SIRS)lasting 48 hours(91.3％vs.71.8％),ICU admission(70.4％vs.17.6％),and length-of-stay([32±17.7]days vs.[19.0±12.2]days)compared to those of the non-MOF group(P＜0.05).The incidences of respiratory,circulatory,and renal failures were higher in the MOF group than those in the non-MOF group,showing significant differences in circulatory failure(69％vs.3.5％)and renal failure(65.5％vs.3.5％)(P＜0.05).In the first 5 days of hospitalization,the MOF group showed significantly elevated BUN and Cr levels,while Alb and TP levels dropped rapidly upon admission and then gradually recovered.The NAPP level of the MOF group continued to decrease after admission,and on the third day after admission,the NAPP level was lower than that of the Non-MOF group,showing statistically significant difference(P＜0.001).The Alb/NAPP ratio of the MOF group decreased significantly on day 1 and then rapidly increased,showing significant differences between the groups on days 3 and 4(P=0.001).Subgroup analysis of MOF patients with moderate-to-severe IAH revealed similar trends in the dynamic changes and the overall changes in the indicators,and the difference was even more pronounced.The mixed linear model showed that the average levels of HCT,BUN,Alb/NAPP,and Alb/TP were higher and increased over time in the MOF combined with IAP subgroup(P＜0.001).Conclusion The CLS model of SAP patients is validated,confirming that CLS is a key factor in the progression from SIRS to MOF.The loss of NAPP is an early and important indicator of CLS persistence and progression to MOF.Additionally,moderate-to-severe IAH accelerates the deterioration of MOF.These findings provide valuable insights into the potential mechanisms of MOF and warrant further validation through large-scale prospective studies.

Objective To investigate the diagnostic value of 4 novel inflammatory markers related to routine blood tests,namely neutrophil-to-lymphocyte ratio(NLR),red blood cell distribution width(RDW),hemoglobin-to-RDW ratio(HRR)and systemic immune-inflammation index(SII),in elderly patients with chronic cardiovascular disease(CVD)complicated with frailty.Methods Retrospectively analyze 110 patients with chronic stable CVD who were hospitalized in the cadre ward of cardiovascular medicine at the Air Force Characteristic Medical Center from January 2022 to June 2023.According to the assessment results of the Fried scale,they were divided into three groups:non-frailty group(Fried score=0,n=30),the pre-frailty group(Fried score 1 or 2,n=40)and frailty group(Fried score≥3,n=40).The differences in general information,the impairment rate of daily living activities,miniature nutritional assessment-short form(MNA-SF)scores,mini-mental state examination(MMSE)scores,and the indicators such as NLR,RDW,HRR,and SII among the three groups were compared.Spearman rank correlation was used to analyze the correlation between NLR,RDW,HRR,SII and frailty scores as well as each frailty indicator.Multivariate logistic regression analysis was performed to identify the independent risk factors for frailty in elderly patients with chronic CVD,and the receiver operating characteristic(ROC)curve was used to assess the clinical diagnostic value of NLR and HRR in elderly patients with chronic CVD complicated with frailty.Results Compared with non-frailty group and pre-frailty group,patients in frailty group were older,with higher impaired rates of daily living activities,NLR,RDW,and SII,and lower MNA-SF scores,MMSE scores,and HRR,and differences were statistically significant(P<0.05).Spearman rank correlation analysis showed that the frailty score was positively correlated with NLR(rs=0.354,P<0.001),and RDW(rs=0.448,P<0.001),negatively correlated with HRR(rs=-0.232,P=0.024),and had no significant correlation with SII(rs=0.144,P=0.167).Further analysis of the correlation between the above novel inflammatory markers and the 5 components of frailty showed that NLR was positively correlated with fatigue(rs=0.228,P=0.017),slowed walking speed(rs=0.299,P<0.001),and low physical function(rs=0.319,P<0.001);RDW was positively correlated with decreased grip strength(rs=0.321,P<0.001),slowed walking speed(rs=0.422,P<0.001),and low physical function(rs=0.246,P=0.001);and HRR was negatively correlated with slowed walking speed(rs=-0.230,P=0.025),and low physical function(rs=-0.299,P=0.003).Multivariate logistic regression analysis showed that MNA-SF score(OR=0.577,95%CI 0.342-0.973)was an independent protective factor for pre-frailty in elderly patients with chronic CVD(P<0.05);NLR(OR=7.866,95%CI 1.101-56.185)was an independent risk factor for frailty,while HRR(OR=0.344,95%CI 0.120-0.983)and MNA-SF score(OR=0.292,95%CI 0.146-0.580)were independent protective factors for frailty in elderly CVD patients(P<0.05).The area under the ROC curve of NLR and HRR for diagnosing frailty in elderly patients with chronic CVD were 0.778 and 0.749,respectively.Conclusion NLR and HRR have high clinical diagnostic value for frailty in elderly patients with chronic CVD,and are expected to become effective inflammatory markers for screening elderly patients with chronic CVD complicated with frailty.

Objective To investigate the characteristics of changes in hepatitis B surface antigen(HBsAg),hepatitis B virus(HBV)deoxyribonucleic acid(DNA),and alanine aminotransferase(ALT)levels following the cessation of nucleos(t)ide analogues(NAs)therapy in hepatitis B e antigen(HBeAg)-negative chronic hepatitis B(CHB)patients with baseline HBsAg levels<1000 IU/ml.Methods This retrospective cohort study analyzed 73 HBeAg-negative CHB patients treated at the Fifth Medical Centre of Chinese PLA General Hospital from January 2020 to June 2023.Patients were divided into 3 groups according to baseline HBsAg level and discontinuation strategy:HBsAg-negative discontinuation group(n=14),HBsAg-positive discontinuation group(n=25),and HBsAg-positive continuation group(n=34).All patients were followed for 48 weeks.Baseline clinical characteristics and changes in virological and hepatic biochemical indicators during follow-up were compared among the 3 groups.Univariate logistic regression analysis was performed to assess the correlation between clinical indicators and HBV DNA reappearance in HBsAg-positive discontinuation group,and between clinical indicators and HBsAg decline>0.5 log IU/ml in this group.Results There were no significant differences in the baseline levels of gender,age,albumin,and total bilirubin among the 3 groups(P>0.05).The baseline direct bilirubin level was significantly higher in HBsAg-positive discontinuation group than that in other groups(P<0.05),while the lymphocyte counts were significantly higher in HBsAg-negative discontinuation group(P<0.05).During the 48-week follow-up period,the HBV DNA reappearance rate in HBsAg-positive discontinuation group(72.0%)was significantly higher than that in other groups(P<0.001).There was no significant difference in the incidence of ALT elevation among the three groups(P=0.260).The proportion of patients with HBsAg decline>0.5 log IU/ml in HBsAg-positive discontinuation group(24.0%)was significantly higher than that in HBsAg-positive continuation group(5.9%,P<0.05).The proportion of patients with HBsAg increase>0.5 log IU/ml in HBsAg-positive discontinuation group(12.0%)was also significantly higher than that in HBsAg-positive continuation group(0%,P<0.05).Univariate logistic regression analysis revealed no significant association between the analyzed clinical indicators and HBsAg decline(P>0.05).Conclusions Discontinuation of NAs therapy in HBsAg-negative patients demonstrates high safety,with sustained HBsAg negativity post-cessation and low risks of viral relapse and liver function abnormalities.For HBsAg-positive patients,discontinuation may promote HBsAg decline in some individuals but is associated with risks of HBV DNA reappearance and HBsAg elevation.The decision to discontinue therapy should be comprehensively evaluated based on patients'baseline HBsAg levels and clinical characteristics.

Clinically,the incidence of chronic musculoskeletal pain is relatively high,and it is one of the main causes of disability in Chinese residents,causing a heavy health and economic burden to the society.There are limited treatments available for patients who are ineffective to conservative treatment and whose disorders are inoperable.Recently,transcatheter embolization(TCE)has become a potential treatment method for such patients.Chronic musculoskeletal pain,such as knee osteoarthritis,adhesive capsulitis of the shoulder(frozen shoulder),tendinopathy,and neck/back muscle pain,can induce pathological neovascularization and inflammatory reactions.TCE of abnormal neovasculature can improve patient's pain and limb function.So far,there are relatively few studies on the TCE of chronic musculoskeletal pain in China,and there are no large-scale high-quality clinical studies abroad.This paper aims to make a comprehensive review about the TCE for chronic musculoskeletal pain,focusing on its basic principles,operative techniques,and latest clinical achievements.

Objective Aedes albopictus is the primary vector of the dengue virus.Screening and the analysis of immune-related genes in DENV2-infected Ae.albopictus provides a scientific basis for further research on blocking the extrinsic incubation period of the dengue virus.Methods Through the approach of literature mining,thirty-three potential immune-related genes were screened from species such as Aedes aegypti and Anopheles gambiae,which have a close genetic relationship with Ae.albopictus.The protein—protein interaction(PPI)analysis is employed to explore the interaction relationship of the proteins encoded by genes.The alterations in mRNA expression levels of the relevant genes in DENV2-infected Ae.albopictus midgut were detected using the qRT-PCR method.Results The PPI results indicates that TLR and Spz of Ae.albopictus;Rel1,Rel2,DefC,Spz,PIWI,Ago2,DOME and HOP of Ae.aegypti;and Rel1,Rel2,CACT,STAT and DOME of An.gambiae exhibit PPI relationships.After Ae.albopictus was infected with DENV2,10 genes showed significant difference in expression.Ago3(7.39,P<0.05),DOMEa(1.63,P<0.01),DOMEb(21.29,P<0.001),and TLRb(1.61,P<0.05)were significantly up-regulated.Rel1(0.62,P<0.001),CACTl(0.65,P<0.001),Rel2a(0.65,P<0.01),Rel2b(0.24,P<0.001),GATAa(0.64,P<0.01)and DefC(0.28,P<0.05)were significantly down-regulated.Conclusions The concordance of Ae.albopictus with Ae.aegypti was higher than that with An.gambiae.DOMEb,Ago3,Rel2b and DefC,can serve as the preferred target genes for subsequent studies on DENV2 immune blockade.
