Sustained inflammatory responses are closely related to various severe diseases,and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment.Natural products have garnered considerable concern for the treatment of inflammation.Huanglian-Wumei decoction(HLWMD)is a classic prescription used for treating inflammatory diseases,but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated.Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory,we successfully obtained berberine(BBR)-chlorogenic acid(CGA)supramolecular(BCS),which is an herbal pair from HLWMD.Using a series of characterization methods,we confirmed the self-assembly mechanism of BCS.BBR and CGA were self-assembled and stacked into amphiphilic spherical supra-molecules in a 2:1 molar ratio,driven by electrostatic interactions,hydrophobic interactions,and π-πstacking;the hydrophilic fragments of CGA were outside,and the hydrophobic fragments of BBR were inside.This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules.Compared with free molecules,BCS significantly attenuated the release of multiple inflammatory mediators and lipopolysaccharide(LPS)-induced pyroptosis.Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB(NF-κB)p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase-11.

OBJECTIVE T o verify and compare the values of the different risk assessment scores in prediction of in-fections in the ST elevation myocardial infarction(STEMI)patients undergoing percutaneous coronary interven-tion(PCI)therapy.METHODS A total of 226 STEMI patients who received PCI in The Second Medical Center of Chinese PLA General Hospital from Aug.2019 to Jul.2024 were recruited as the research subjects.The efficien-cies of the six types of risk assessment scores,including age,serum creatinine,or glomerular filtration rate/ejec-tion fraction(ACEF/AGEF)score,Canadian acute coronary syndrome(C ACS)score,embolism risk score 2(CHADS2)score,global register of acute coronary events(GRACE)score and for contrast induced nephropathy(Mehran)scorein prediction of infections and major adverse clinical events(M ACE)were analyzed.RESULTS All of the risk assessment scores showed remarkable discriminating capability in prediction of infections(AUC:0 746 to 0 791)except CHADS2 score[the area under the curve(AUC)=0.682;95％CI=0.652 to 0.712)].All of the risk assessment scores showed the excellent performance in calibration of infections except CACS risk assess-ment score(calibration slope=0.77;95％CI=0.18 to 1.35).The risk assessment scores also showed tremen-dous capability in discriminating MACE during the hospital stay except CHADS2 score,with the AUC ranging be-tween 0.700 and 0.786.All of the six types of risk assessment scores showed the most excellent performance in calibration of MACE during the hospital stay.CONCLUSION ACEF,AGEF,CACS,GRACE and Mehran scores show remarkable discriminating capability and calibration in prediction of infections and MACE.

Objective To compare the periodontally accelerated osteogenic orthodontics(PAOO)effects of corticotomy with full mu-coperiosteal flap(flapped corticotomy)and corticotomy-only on accelerating orthodontic tooth movement.Methods A total of 60 healthy male SD rats(weighing 180-200 g)were selected and randomly divided into three groups.There were 20 rats each in the flapped corticotomy group,the corticotomy-only group,and the control group.After applying orthodontic instruments,5 rats each in the surgical group and the control group were killed by excessive anesthesia on 0,1,3,and 7 days after tooth movement.The tooth move-ment distances of the rats in the control group and the experimental group were counted,and immunohistochemical staining was per-formed to observe the corresponding molecular biological changes.Results There was no significant difference in accelerating ortho-dontic tooth movement between the flapped corticotomy group and the corticotomy-only group.Compared with traditional orthodontic tooth movement,both the flapped corticotomygroup and the corticotomy-only group could bring an increase in the expression of RANKL on the pressed periodontal side while there was no significant difference between the two experimental groups.Both the flapped corticot-omy and non-flapped corticotomy could enlarge the area of tissue formation in the periodontal tension zone,and still there was no signif-icant difference between the two surgical methods.Compared with traditional orthodontic tooth movement,both the flapped corticotomy group and the corticotomy-only group could lead to an increase in ALP,OCN and OPN expression on the periodontal tension zone.Conclusion Both flapped corticotomy and corticotomy play a significant role in accelerating orthodontic tooth movement and promoting alveolar bone formation in the early stage.Both surgical methods of PAOO can provide more efficient and stable biological support for orthodontic treatment.

Objective:To analyze the etiology and prognosis of intracranial hemorrhage in children and provide a basis for the prevention of intracranial hemorrhage in children.Methods:A retrospective analysis was conducted on the clinical data of children with intracranial hemorrhage aged 29 days to 14 years admitted to the First People′s Hospital of Yulin from January 2012 to December 2022.Results:There were a total of 535 children with intracranial hemorrhage, including 355 boys and 180 girls. The high-incidence age ranged from 29 days to 1 year, with 235 cases (43.93%). The common causes of intracranial hemorrhage were as follows: falling from heights 27.48%(147/535), late-onset vitamin K deficiency 20.56%(110/535), and car accidents 9.53%(51/535). Spontaneous intracranial hemorrhage was more common in infants, while traumatic intracranial hemorrhage was more common in young children. The mortality rate of children with intracranial hemorrhage was 14.20%(69/486), and the disability rate was 14.81%(72/486). Univariate analysis showed that late-onset vitamin K deficiency, leukemia, flat fall, car accident, subdural hemorrhage, cerebral parenchymal hemorrhage, subarachnoid hemorrhage, and multi-site hemorrhage were associated with the poor prognosis (disability and death) of intracranial hemorrhage in children (all P<0.05). Multivariate analysis showed that late-onset vitamin K deficiency and cerebral parenchymal hemorrhage were independent risk factors for intracranial hemorrhage disability in children (all P<0.05); Leukemia and cerebral parenchymal hemorrhage are independent risk factors for intracranial hemorrhage death in children (all P<0.05). Conclusions:The incidence of intracranial hemorrhage in boys is higher than that in girls, with the highest incidence in infants aged 29 days to 1 year. Intracranial hemorrhage in children is commonly caused by falls from heights, late-onset vitamin K deficiency and car accidents. Late-onset vitamin K deficiency and cerebral parenchymal hemorrhage are independent risk factors for disability, while leukemia and cerebral parenchymal hemorrhage are independent risk factors for death. Preventing various causes of intracranial hemorrhage is an important measure to reduce intracranial hemorrhage in children.

Objective　To understand the impact of early and timely treatment and initial antiviral treatment regimen on mortality and attrition of antiretroviral therapy. Methods A retrospective cohort study was conducted using download data on antiretroviral therapy for HIV-infected patients in Liuzhou City, Guangxi Province, from the database of the Basic Information System for AIDS Control and Prevention (BISAC) from 2010 to 2020. The Cox proportional risk regression model was used to analyze the influencing factors of mortality and attrition. Results A total of 15 713 infected patients were included, including 53.4% aged 18-<50 years, 69.4% male, 61.0% farmer, 75.1% CD4 count <350 cells /μL before initial antiviral treatment, the overall mortality rate was 4.30/100 person-years, and the overall attrition was 2.42/100 person-years. The results of Cox regression analysis showed that the influencing factors of mortality were pretreatment CD4 counts of 350-<500 cells/μL(AHR=0.72, 95%CI: 0.63-0.81) and ≥500 cells/μL (AHR= 0.64, 95%CI: 0.55-0.76); duration from diagnosis to initial antiviral treatment 91-180 days (AHR=1.25, 95%CI: 1.08-1.45), 181-365 days (AHR=1.26, 95%CI: 1.08-1.47), and ≥365 days (AHR=1.26, 95%CI: 1.11-1.44); initial antiviral treatment regimens of D4T+3TC+EFV/NVP (AHR=1.47, 95%CI: 1.32-1.63) and AZT/D4T/TDF+3TC+LPV/r (AHR=1.73, 95%CI: 1.50-1.99). Factors affecting attrition were pretreatment CD4 counts of 350-499 cells/μL (AHR=1.32, 95%CI: 1.16-1.50) and ≥500 cells/μL (AHR=1.28, 95%CI: 1.10-1.50); interval from HIV positivity confirmation to initial dosing ≥365 days (AHR=1.21, 95%CI: 1.04-1.40), initial antiviral treatment regimens of TDF+3TC+NVP (AHR=1.32, 95%CI: 1.13-1.55), AZT+3TC+EFV/NVP (AHR=1.43, 95%CI: 1.26-1.62) and AZT/D4T/TDF+3TC+LPV/r (AHR=1.33, 95CI%: 1.06-1.67). Conclusions　Early and timely treatment and the initial antiviral treatment regimen of TDF+3TC+EFV have good efficacy, but attention should be paid to the high risk of attrition of HIV-infected people with high CD4 count before treatment.

Objective:To analyze immune reconstitution and influencing factors in HIV infected men who have sex with men (MSM) with access to antiviral therapy (ART) in Guangxi Zhuang Autonomous Region (Guangxi) during 2005-2021.Methods:The data were collected from Chinese Disease Prevention and Control Information System. The study subjects were HIV infected MSM with access to the initial ART for ≥24 weeks in Guangxi from 2005 to 2021 and HIV RNA lower than the detection limit within 24 months. The proportion of infected MSM who had immune reconstitution after ART was calculated. Cox proportional hazard regression model was used to analyze the influencing factors of immune reconstitution. Software SPSS 24.0 was used for statistical analysis.Results:A total of 3 200 HIV infected MSM were enrolled, in whom 15.56 % (498/3 200) had no immune reconstitution, 14.78% (473/3 200) had moderate immune reconstitution, and the rate of complete immune reconstitution was 69.66% (2 229/3 200). The M ( Q1, Q3) of ART time for immune reconstitution was 12 (5, 27) months. Multivariate Cox proportional risk regression model analysis results showed that compared with those with initial ART at age ≥30 years, WHO clinical stage Ⅲ/Ⅳ illness, baseline BMI <18.50 kg/m 2 and baseline CD4 +T lymphocyte (CD4) counts <200 cells/μl, HIV infected MSM with initial ART at age <30 years, WHO clinical stageⅠ/Ⅱ illness, baseline BMI≥24.00 kg/m 2 and baseline CD4 counts ≥200 cells/μl were more likely to have complete immune reconstitution. Conclusions:In the HIV infected MSM in Guangxi, failures to achieve moderate and complete immune reconstitution were observed. Surveillance and ART regimen should be improved for key populations, such as those with older age and low baseline CD4 counts.
