Objective: To analyze the trends, gender, and age differences in the incidence of lip and oral cavity cancer in Chinese population from 1990 to 2021 and predict future incidence trends, providing a scientific basis for disease prevention and public health policy. Methods: Incidence data of lip and oral cavity cancer in Chinese population from the Global Burden of Disease (GBD) database from 1990 to 2021 were analyzed. The Joinpoint regression model was used to assess temporal trends, the age-period-cohort model was used to evaluate the independent effects of age, period, and cohort, and the Bayesian age-period-cohort model (BAPC) model was used to predict incidence trends from 2022 to 2044. Results: From 1990 to 2021, the age-standardized incidence rate of lip and oral cavity cancer in Chinese population increased from 2.39/100 000 to 3.76/100 000, and the crude incidence rate rose from 1.71/100 000 to 4.85/100 000. The incidence rate in males was higher and increased more rapidly than in females. Higher incidence rates were prevalent among older populations, a rapid increase in incidence rates occurred during 2003 to 2012, and earlier birth cohorts showed overall higher risks. BAPC predictions indicated a continued rise in incidence from 2022 to 2044. During this period, male incidence stabilized while female incidence increased at a relatively faster rate. Conclusion The incidence of lip and oral cavity cancer in Chinese population has revealed a continuous upward trend, particularly among males and older populations. Future prevention strategies should focus on these high-risk populations.

Based on the "sweat pore-qi and liquid-collaterals" theory， it is considered that the core pathogenesis of pediatric infectious mononucleosis lies in the obstruction of sweat pores， the failure of qi and liquid to disperse， and damage to the collaterals due to pathogenic toxins. Accordingly， the treatment principles proposed include unblocking the sweat pores， regulating qi and liquid， and smoothing the collaterals. In clinical practice， treatment is differentiated according to stages： initial， acute， and late stages. In the initial stage， invasion of warm pathogenic toxins into the lung defense leads to obstruction of the sweat pores， which should be treated by unblocking the sweat pores and expelling pathogens outward. In the acute stage， the obstruction of the sweat pores worsens， leading to the failure of qi and liquid dispersal， resulting in intense heat toxins with accumulation of dampness， phlegm， and blood stasis， which should be treated by promoting qi movement， resolving dampness and phlegm， clearing heat， detoxifying， and dispersing stasis to regulate qi and liquid. In the late stage， residual pathogens remain， with qi and yin deficiency and unsmooth collaterals， which should be treated by unblocking the collaterals， dissipating nodules， tonifying qi， and nourishing yin to smooth the collaterals. This approach may provide new insights for the clinical treatment of pediatric infectious mononucleosis.

Aim To investigate the protective effect of Jujing formula on retina of mice with dry age-related macular degeneration(AMD).Methods The mouse model of dry AMD was induced by intraperitoneal in-jection of sodium iodate,and the prognosis was given to the Jujing formula.Retinal thickness was detected by optical coherence tomography(OCT),the retinal morphological changes were observed by hematoxylin-eosin(HE)staining,and the apoptosis of retinal cells was detected by in situ terminal transferase labeling(TUNEL)staining.Combination of tumor necrosis fac-tor-α(TNF-α),interleukin-6(IL-6)and interleukin-1β(IL-1 β)in eyeballs and serum,superoxide dis-mutase(SOD),glutathione(GSH)and malondialde-hyde(MDA)were evaluated to assess the protective effects of Jujing formula on retinal injury in mice with dry AMD.Results The results of OCT,HE and TUNEL staining showed that Jujing formula significant-ly improved the retinal injury induced by sodium iodate in mice with dry AMD,increased the retinal thickness(P＜0.05),reduced the apoptosis of retinal cells(P＜0.01),and increased the levels of GSH,IL-6 and SOD activity in eyeballs and serum(P＜0.01).The levels of TNF-α,IL-6,IL-1β and MDA were reduced(P＜0.01).Conclusions Jujing formula has certain therapeutic effects on retinal injury in dry AMD,which may be related to inhibiting inflammatory response and enhancing antioxidant capacity.

Objective To explore the clinical efficacy of double beam double tunnel enhanced reconstruction technique in the treatment of knee anterior cruciate ligament(ACL)training injuries.Methods Twenty-nine cases of ACL injury of knee joint from January 2021 to December 2021 were retrospectively analyzed.All the cases were underwent ligament reconstruc-tion surgery.Cases were grouped by surgical technique:there were 14 patients in conventional reconstruction group,including 13 males and 1 female,aged from 22 to 31 years old with an average of(27.07±7.28)years old,autogenous hamstring tendon was used for ligament reconstruction.There were 15 patients in the enhanced reconstruction group,including 13 males and 2 females,aged from 25 to 34 years old with an average of(29.06±4.23)years old,double tunnel ligament reconstruction,the autogenous hamstring muscle was used as the anteromedial bundle,and the posterolateral bundle was replaced by a high-strength line.The difference between knee tibial anterior distance,Lysholm score,International Knee Literature Committee(IKDC)subjective score,Tegner motor level score and visual analog scale(VAS)at 6th and 12th months after the surgery,limb symmetry index(LSI)were recorded at the last follow-up and surgery-related adverse effects during follow-up.Results All patients were followed up,ranged from 13 to 15 months with an average of(13.7±0.8)months.There were no serious adverse reactions related to surgery during the period.There was no statistical difference between the preoperative general data and the observation index of the two groups(P＞0.05).The difference in tibial anterior distance at 6 and 12 months in the enhanced re-construction group(1.45±0.62)mm and(1.74±0.78)mm which were lower those that in the conventional reconstruction group(2.42±0.60)mm and(2.51±0.63)mm(P＜0.05).There was no significant difference in postoperative Lysholm score,Tegner motor level score,IKDC score,VAS,and limb symmetry index at the last follow-up(P＞0.05).Conclusion The enhanced recon-struction technique can more effectively maintain the stability of the knee joint and has no significant effect on the postoperative knee joint function compared with the traditional ligament reconstruction technique.The short-term curative effect is satisfac-tory,and it is suitable for the group with high sports demand.

Objective To explore the effects of dihydromyricetin on the proliferation,apoptosis,and invasion of endometrial cancer(EC)cells and its possible mechanisms.Methods Ishikawa cells in the logarithmic growth phase were taken and divided into the control group,20 μmol/L dihydromyricetin intervention group,40 μmol/L dihydromyricetin intervention group,and 80 μmol/L dihydromyricetin intervention group,which were treated with different final concentrations of dihydromyricetin(0 μmol/L,20 μmol/L,40 μmol/L,80 μmol/L).Then,CCK-8 assay and flow cytometry were used to detect the effects of dihydromyricetin on the cell proliferation and apoptosis.Transwell experiment was used to detect the effect of dihydromyricetin on the cell invasion.qRT-PCR and Western blot were used to detect the effects of dihydromyricetin on the cell expression of miR-21 and PTEN.Results Compared with the control group,the cell proliferation inhibition rate and apoptosis rate in the dihydromyricetin intervention group were significantly increased(P<0.05),and gradually increased with the increase of dihydromyricetin concentration(P<0.05).Compared with the control group,the numbers of migration and invasion cells in the dihydromyricetin intervention group were significantly decreased(P<0.05),and gradually decreased with the increase of dihydromyricetin concentration(P<0.05).Compared with the control group,the cell expression of miR-21 in the dihydromyricetin intervention group was significantly decreased(P<0.05),and gradually decreased with the increase of dihydromyricetin concentration(P<0.05),the expression levels of PTEN mRNA and protein were significantly increased(P<0.05),and gradually increased with the increase of dihydromyricetin concentration(P<0.05).Conclusion Dihydromyricetin can inhibit the growth and metastasis of EC cells,and the inhibitory effect is positively correlated with its concentration.The mechanism may be related to the effect of dihydromyricetin on the miR-21/PTEN signaling pathway of EC cells.

Objective:To explore the views of adolescents with asthma on factors affecting disease self-management, so as to provide a basis for improving self-management of asthma children, and propose improvement suggestions.Methods:This study was a descriptive qualitative study. From February to June 2023, 10 to 17 year old children with asthma were recruited at the Asthma Clinic of the Children's Hospital affiliated to Capital Institute of Pediatrics through purposive sampling. One-on-one semi-structured interviews were conducted around self-management and its related factors, and the thematic analysis was used to analyse interview materials.Results:A total of 17 adolescents with asthma, aged (13.00±2.03) years, with a course of disease of (5.00±2.85) years, were included. The interview materials included two aspects, namely facilitators and barriers of self-management. The facilitators were coded into three themes and seven sub-themes, including the individual management awareness of children with asthma (sense of responsibility, compliance awareness), social support (parental care and compensation, teacher and classmate support, patient interaction), and health education (health guidance from doctors and nurses, school health propaganda). Barriers were encoded into three themes and six sub-themes, including disease cognition (demand competition, importance), social environment (interpersonal interaction, physical environment), and healthcare services (accessibility of medical services, school related medical resources) .Conclusions:The self-management of adolescents with asthma is affected by multiple factors. Individual management awareness, social support, and health education can promote self-management in children with asthma, while unfavorable factors in disease cognition, social environment, and healthcare services can hinder self-management in children with asthma. Medical and nursing staff should develop and implement empowerment plans for self-management of asthma children, by mobilizing multi-channel medical resources, providing multi-dimensional full process empowerment, and helping asthma children build a diverse interpersonal support network system, in order to promote effective health management transition for adolescents with asthma.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the distribution and antimicrobial resistance profiles of the common pathogens isolated from urine from 2015 to 2021 in the CHINET Antimicrobial Resistance Surveillance Program.Methods The bacterial strains were isolated from urine and identified routinely in 51 hospitals across China in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Antimicrobial susceptibility was determined by Kirby-Bauer method,automatic microbiological analysis system and E-test according to the unified protocol.Results A total of 261 893 nonduplicate strains were isolated from urine specimen from 2015 to 2021,of which gram-positive bacteria accounted for 23.8％(62 219/261 893),and gram-negative bacteria 76.2％(199 674/261 893).The most common species were E.coli(46.7％),E.faecium(10.4％),K.pneumoniae(9.8％),E.faecalis(8.7％),P.mirabilis(3.5％),P.aeruginosa(3.4％),SS.agalactiae(2.6％),and E.cloacae(2.1％).The strains were more frequently isolated from inpatients versus outpatients and emergency patients,from females versus males,and from adults versus children.The prevalence of ESBLs-producing strains in E.coli,K.pneumoniae and P.mirabilis was 53.2％,52.8％and 37.0％,respectively.The prevalence of carbapenem-resistant strains in E.coli,K.pneumoniae,P.aeruginosa and A.baumannii was 1.7％,18.5％,16.4％,and 40.3％,respectively.Lower than 10％of the E.faecalis isolates were resistant to ampicillin,nitrofurantoin,linezolid,vancomycin,teicoplanin and fosfomycin.More than 90％of the E.faecium isolates were ressitant to ampicillin,levofloxacin and erythromycin.The percentage of strains resistant to vancomycin,linezolid or teicoplanin was＜2％.The E.coli,K.pneumoniae,P.aeruginosa and A.baumannii strains isolated from ICU inpatients showed significantly higher resistance rates than the corresponding strains isolated from outpatients and non-ICU inpatients.Conclusions E.coli,Enterococcus and K.pneumoniae are the most common pathogens in urinary tract infection.The bacterial species and antimicrobial resistance of urinary isolates vary with different populations.More attention should be paid to antimicrobial resistance surveillance and reduce the irrational use of antimicrobial agents.

Objective To understand the distribution and changing resistance profiles of clinical isolates of Enterococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Enterococcus according to the unified protocol of CHINET program by automated systems,Kirby-Bauer method,or E-test strip.The results were interpreted according to the Clinical & Laboratory Standards Institute(CLSI)breakpoints in 2021.WHONET 5.6 software was used for statistical analysis.Results A total of 124 565 strains of Enterococcus were isolated during the 7-year period,mainly including Enterococcus faecalis(50.7％)and Enterococcus faecalis(41.5％).The strains were mainly isolated from urinary tract specimens(46.9％±2.6％),and primarily from the patients in the department of internal medicine,surgery and ICU.E.faecium and E.faecalis strains showed low level resistance rate to vancomycin,teicoplanin and linezolid(≤3.6％).The prevalence of vancomycin-resistant E.faecalis and E.faecium was 0.1％and 1.3％,respectively.The prevalence of linezolid-resistant E.faecalis increased from 0.7％in 2015 to 3.4％in 2021,while the prevalence of linezolid-resistant E.faecium was 0.3％.Conclusions The clinical isolates of Enterococcus were still highly susceptible to vancomycin,teicoplanin,and linezolid,evidenced by a low resistance rate.However,the prevalence of linezolid-resistant E.faecalis was increasing during the 7-year period.It is necessary to strengthen antimicrobial resistance surveillance to effectively identify the emergence of antibiotic-resistant bacteria and curb the spread of resistant pathogens.
