Objective:To compare the impact of manual right arm blood pressure measurement with computer-controlled blood pressure meter (CCBPM) on the detection rate of hypertension among elderly individuals.Method:This was a cross-sectional study. Elderly residents undergoing routine health check-up in a village in Jiangxi Province from April to June 2024 were enrolled. Manual blood pressure measurements were performed on the right arm using an electronic sphygmomanometer, while standardized dual-arm synchronized blood pressure assessments were conducted using the CCBPM. Blood pressure data were recorded from three sources: manual measurement on the right arm; the first CCBPM measurement on the arm with higher systolic blood pressure (CCBPM single); and the mean blood pressure of the arm with higher systolic blood pressure from two (if the difference between the first two measurements was less than 5 mmHg, 1 mmHg=0.133 kPa) or three (if the difference exceeded 5 mmHg) CCBPM measurements (CCBPM mean). Hypertension detection rates from these three datasets were compared. Subgroup analysis was performed according to age (60-74 years old as the elderly group,≥75 years old as the senior group) and gender. Intra-group correlation coefficient ( ICC) was analyzed to evaluate the consistency of blood pressure data of different blood pressure measurement methods, and Kappa value was analyzed to evaluate the consistency of hypertension classification determined by different blood pressure measurement methods. Results:A total of 1 498 participants were enrolled, aged (71.30±6.83) years old, including 678 males (45.26%). The blood pressure and heart rate measured by the artificial right arm blood pressure measurement were higher than those measured by CCBPM single (blood pressure: (140.09±17.19)/(82.40±10.93) mmHg vs. (135.31±18.98)/(81.23±10.51) mmHg; heart rate: (75.76±11.72) beats/min vs.(72.94±11.21) beats/min) and CCBPM mean (blood pressure: (140.09±17.19)/(82.40±10.93) mmHg vs. (134.64±18.39)/(80.28±9.78) mmHg; heart rate: (75.76±11.72) beats/min vs. (72.87±10.70) beats/min, all P<0.05). The detection rate of hypertension determined by CCBPM mean was significantly lower than that of artificial right arm (40.25% (603/1 498) vs.54.34% (814/1 498)) and CCBPM single (40.25% (603/1 498) vs. 44.79% (671/1 498), all P<0.05). Subgroup analysis showed that that the detection rate of hypertension determined by CCBPM mean was lower than that measured by artificial right arm regardless of gender and age (all P<0.05). The consistency of blood pressure data between artificial right arm and the CCBPM mean was moderate (systolic blood pressure: ICC=0.70; diastolic blood pressure: ICC=0.62), with less consistent classification ( Kappa=0.37). The consistency of blood pressure data between CCBPM single and CCBPM mean is extremely high (systolic blood pressure: ICC=0.94; diastolic blood pressure: ICC=0.91), with highly consistent classification ( Kappa=0.74). Conclusions:Artificial right arm blood pressure measurement in physical examinations may overestimate the hypertension detection rate, and the standardized dual-arm synchronized blood pressure measurement using CCBPM can reduce irregular blood pressure measurement.

Dental caries,a chronic disease characterized by tooth decay,occupies the second position in terms of disease burden and is primarily caused by cariogenic bacteria,especially Streptococcus mutans,because of its acidogenic,aciduric,and biofilm-forming capabilities.Developing novel targeted anti-virulence agents is always a focal point in caries control to overcome the limitations of conventional anti-virulence agents.The current study represents an up-to-date review of in silico approaches of drug design against dental caries,which have emerged more and more powerful complementary to biochemical attempts.Firstly,we categorize the in silico approaches into computer-aided drug design(CADD)and AI-assisted drug design(AIDD)and highlight the specific methods and models they contain respectively.Subsequently,we detail the design of anti-virulence drugs targeting single or multiple cariogenic virulence targets of S.mutans,such as glucosyltransferases(Gtfs),antigen Ⅰ/Ⅱ(AgⅠ/Ⅱ),sortase A(SrtA),the VicRK signal transduction system and superoxide dismutases(SODs).Finally,we outline the current opportunities and challenges encountered in this field to aid future endeavors and applications of CADD and AIDD in anti-virulence drug design.

Objective:The composition and function of dental plaque biofilm are susceptible to alterations,potentially leading to vari-ous oral diseases.Although mesoporous bioactive glass(MBG)has been widely used,how it affects the microbial composition and bio-logical function of dental plaque biofilm remains unclear.This study aims to investigate the effects of MBG on the composition and bio-logical function of viable bacteria in dental plaque in vitro.Methods:At first,MBG was synthesized and characterized.Subsequently,the MBG was applied to dental plaque biofilm in vitro for a short term.The impact on biofilm biomass was assessed through colony-forming unit(CFU)counting.MBG-treated samples were collected for metatranscriptomic analyses of species composition and differen-tially expressed genes.Finally,reverse transcription quantitative polymerase chain reaction(RT-qPCR)was performed to validate the expression of core DEGs.Results:The results of CFU counting showed that short-term MBG treatment reduced dental plaque biofilm biomass in vitro by 44.25%.The results of metatranscriptomics showed that MBG significantly changed the species composition of den-tal plaque biofilm,where commensal Streptococci and Klebsiella were predominant.The function of carbohydrate metabolism was up-regulated,and the up-regulated genes were mainly enriched in the tricarboxylic acid(TCA)cycle.The results of RT-qPCR showed that a total of 9 genes associated with the TCA cycle were up-regulated.Conclusion:MBG can affect the species composition and enhance the carbohydrate metabolism of dental plaque biofilm in vi-tro,providing a new theoretical basis for the application of MBG in the oral field.

Objective:To observe the effect of large pushing Tianheshui manipulation intervention on the body temperature of young rabbits with endotoxin-induced fever and discuss its antipyretic mechanism.Methods:Thirty-two young rabbits meeting the standards were selected from 40 ordinary young male New Zealand rabbits after being adapted for 7 d,and randomly divided into a normal group,a model group,a large pushing Tianheshui group,and an ibuprofen group according to the random number table method,with 8 rabbits in each group.Rabbits in the model group,the large pushing Tianheshui group,and the ibuprofen group were subjected to preparing the endotoxin-induced fever model by intravenous lipopolysaccharide from the marginal ear vein.Rabbits in the large pushing Tianheshui group received Tuina(Chinese therapeutic massage)manipulation intervention 1.5 h and 2.5 h after modeling,respectively.Rabbits in the ibuprofen group were intragastrically given ibuprofen suspension 1.5 h after modeling.The dynamic changes in body temperature were observed for the young rabbits after fever modeling.Enzyme-linked immunosorbent assay was used to determine the content changes in positive mediators of hypothalamic body temperature,including prostaglandin(PG)E2 and cyclic adenosine monophosphate(cAMP),as well as negative mediators of hypothalamic body temperature,including arginine vasopressin(AVP)and α-melanocyte stimulating hormone(α-MSH).Results:The body temperature of the young rabbits in the model group was significantly higher than that in the normal group at 0.5-4.0 h,5.0 h,and 5.5 h after modeling(P＜0.01),showing two obvious fever peaks in the model group at 1.5 h and 3.0 h after modeling,respectively,with the highest peak at 1.5 h.Compared with the model group,body temperatures of the large pushing Tianheshui group and the ibuprofen group decreased significantly after 0.5 h of intervention(P＜0.05).Compared with the normal group,the contents of PGE2 and cAMP were significantly increased(P＜0.05),and the contents of AVP and α-MSH were significantly decreased(P＜0.01)in the hypothalamus of the model group.Compared with the model group,the contents of PGE2 and cAMP were significantly decreased(P＜0.01),and the levels of AVP and α-MSH were significantly increased(P＜0.01)in the hypothalamus in the large pushing Tianheshui group and the ibuprofen group.There were no significant differences in the PGE2,cAMP,AVP,and α-MSH contents in the hypothalamus between the ibuprofen group and the large pushing Tianheshui group(P＞0.05).Conclusion:Large pushing Tianheshui manipulation has a significant antipyretic effect on endotoxin-induced fever in young rabbits.The mechanism may be related to inhibiting the positive regulators(PGE2 and cAMP)and promoting the negative regulators(AVP and α-MSH)of hypothalamic control of body temperature.
