Objective: To investigate the intentions of mothers of ageappropriate girls in Qingdao to vaccinate their daughters against human papillomavirus (HPV), so as to provide theoretical guidance for targeted health education in the future. Methods: A multistage random sampling method was adopted to conduct a crosssectional study among 2 244 mothers of girls aged 12-14 years in Qingdao from March to December 2023. The Mann-Whitney U test was used for group comparisons, and Logistic regression was performed to analyze the factors that influenced maternal intention to vaccinate their ageappropriate daughters against HPV. Results: Among the surveyed mothers, 89.22% (n=2 002) intended to vaccinate their daughters against HPV, and 68.58% (n=1 539) had fully vaccinated or had plans to complete it for themselves. The knowledge score of mothers intended to vaccinate their daughters was 10 (8, 11). The multivariate Logistic regression analysis showed that mothers aged >45 years (OR=0.19), those with an annual family income of 60 000-<150 000 yuan (OR=0.65), 150 000-<300 000 yuan (OR=0.58), 300 000-500 000 yuan (OR=0.22), and those with higher knowledge scores (OR=0.90) were more likely to vaccinate their daughters (P<0.05). Mothers with a junior college or undergraduate degree (OR=1.66), those who never or occasionally screened for HPV (OR=1.58), those who were intended to be vaccinated, not planning to complete the fullcourse vaccination, or overaged and unvaccinated (OR=7.13), those who were not concerned about their daughters HPV infection (OR=2.54), and those whose daughters were not in adolescence (OR=1.93) were less intended to vaccinate their daughters (P<0.05). The primary reasons for vaccine hesitancy were vaccine safety concerns (65.06%), followed by the belief of mothers that "the children is to young, and can be vaccinated when they are older" (13.25%). Conclusions Mothers of eligible girls in Qingdao have relatively higher intentions to vaccinate their daughters against HPV, and willingness is influenced by factors such as the mothers vaccination status, knowledge level, and daughters development stage. It is recommended to strengthen targeted health education, improve the cognitive level and acceptance of mother, and increase the vaccination rate of HPV vaccines.

As the brain's resident immune cells, microglia perform crucial functions such as phagocytosis, neuronal network maintenance, and injury restoration by adopting various phenotypes. Dynamic imaging of these phenotypes is essential for accessing brain diseases and therapeutic responses. Although numerous probes are available for imaging pro-inflammatory microglia, no PET tracers have been developed specifically to visualize anti-inflammatory microglia. In this study, we present an ¹⁸F-labeled PET tracer (QTFT) that targets the P2Y₁₂, a receptor highly expressed on anti-inflammatory microglia. [¹⁸F]QTFT exhibited high binding affinity to the P2Y₁₂ (14.43 nmol/L) and superior blood-brain barrier permeability compared to other candidates. Micro-PET imaging in IL-4-induced neuroinflammation models showed higher [¹⁸F]QTFT uptake in lesions compared to the contralateral normal brain tissues. Importantly, this specific uptake could be blocked by QTFT or a P2Y₁₂ antagonist. Furthermore, [¹⁸F]QTFT visualized brain lesions in mouse models of epilepsy, glioma, and aging by targeting the aberrantly expressed P2Y₁₂ in anti-inflammatory microglia. In a pilot clinical study, [¹⁸F]QTFT successfully located epileptic foci, showing enhanced radioactive signals in a patient with epilepsy. Collectively, these studies suggest that [¹⁸F]QTFT could serve as a valuable diagnostic tool for imaging various brain disorders by targeting P2Y₁₂ overexpressed in anti-inflammatory microglia.

Objective:To discuss the differences in eosinophil(EOS)infiltration in cervical tissue and its relationship with cervical-related diseases,and to clarify the effect of EOS on the occurrence and development of cervical intraepithelial neoplasia(CIN)and cervical cancer.Methods:The clinical data of 256 patients with cervical diseases were collected and divided into cervical cancer group(n=46,including 26 cases of squamous cell carcinoma,15 cases of adenocarcinoma,and 5 cases of adenosquamous carcinoma),chronic cervicitis group(n=50),CIN stage Ⅰ group(n=50),CIN stage Ⅱ group(n=50),CIN stage Ⅲ group(n=30),and normal group(adjacent normal cervical tissue,n=30)based on their conditions.Colposcopy was used to observe the morphology of cervical tissue of the patients in various groups;thin-layer liquid-based cytology test(TCT)was used to observe the morphology of the cervical exfoliated cells in various groups;hybrid capture-chemiluminescence method was used to detect the human papillomavirus(HPV)infection in cervical tissue of the patients in various groups;HE staining was used to observe the pathomorphology of cervical tissue of the patients in various groups;Congo red staining was used to detect the numbers of EOS infiltration in cervical tissue of the patients in various groups;Pearson correlation analysis was used to analyze the correlation between the number of EOS infiltration and the malignancy degree of cervical cancer.Results:The cervical surface of the patients in normal group was smooth and pink,with uniformly distributed capillaries;the cervical surface of the patients in chronic cervicitis group showed red inflammatory changes,with some accompanied by Nabothian cysts and varying degrees of erosion and ulcers;the patients in CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups showed epithelial ulcers,thickening,and irregular morphology,with mosaic and punctate vessels;the cervical surface of the patients in cervical cancer group showed raised areas with neoplasms and necrotic ulcers,and they were fragile and prone to bleeding.After acetic acid staining,no obvious changes of the patients in normal group were observed.The cervix of the patients in chronic cervicitis group showed slight white changes that lasted for a short time;in CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups,irregular thin acetowhite epithelium with map-like borders was observed,with increasingly acetowhite reactions and larger areas as the stages advanced.The cervix of the patients in cervical cancer group showed thick acetowhite epithelium that lasted longer,with rigid and clear contours.After iodine staining,the cervix of the patients in normal group was brown,with uniform coloration;the cervix of the patients in chronic cervicitis group showed poor coloration in inflammatory lesion areas;the cervix of the patients in CIN stage Ⅰ group showed iodine coloration in metaplastic areas,while the cervix of the patients in CIN stage Ⅲ group showed poor coloration in larger lesion areas;the cervix of the patients in cervical cancer group showed irregular surfaces with cauliflower-like growth and no coloration after iodine staining,appearing orange-yellow or mustard yellow.The TCT observation results showed there were no heteromorphic cells and few inflammatory cells in cervical exfoliated cells of the patients in infiltration in normal group;there were numerous neutrophils and EOS in exfoliated cervical cells without heteromorphic cells in chronic cervicitis group.The heteromorphic binucleated cells with high nuclear-cytoplasmic ratios and deeply stained nuclei were observed in cervical exfoliated cells of the patients in CIN stage Ⅰ and CIN stage Ⅱ groups.More heteromorphic cells with high nuclear-cytoplasmic ratios and irregular nuclear membranes were showed in cervical exfoliated cells of the patients in CIN stage Ⅲ group.The cervical exfoliated cells of the patients in cervical cancer group showed large and prominent nucleoli,clustering into syncytial changes.Compared with normal group,the atypial of cervical exfoliated cells in CIN stage Ⅰ,CIN stage Ⅱ,CIN stage Ⅲ,and cervical cancer groups was increased.The hybrid capture-chemiluminescence results showed that compared with normal and chronic cervicitis groups,the numbers of HPV infection and TCT heteromorphic cells of the patients in CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups were increased(P<0.05);compared with CIN stage Ⅰ,CIN stage Ⅱ,and CIN stage Ⅲ groups,the numbers of HPV infection and TCT heteromorphic cells of the patients in cervical cancer group were increased(P<0.05).The HE staining results showed normal cell morphology and structure in normal group,with infiltration of inflammation cells such as neutrophils,monocytes,macrophages,EOS,and lymphocytes;in chronic cervicitis group,the infiltration of inflammatory cells was increased;in CIN group,the cervical cells showed slightly larger nucleoli and heteromorphic cells,with inflammatory cells mainly distributing around the hetermomorphic cells;in cervical cancer group,the cervical cells showed large and deeply stained nucleoli with significant atypia,and the infiltration of inflammatory cells around the cancer cells was increased.Compared with normal group,the numbers of inflammatory cells and EOS infiltration in cervical tissue of the patients in chronic cervicitis group were increased(P<0.05),and the numbers of inflammatory cells and EOS infiltration of the patients in CIN group were increased(P<0.05);compared with chronic cervicitis group,the number of inflammatory cells and EOS infiltration of the patients in CIN group were decreased(P<0.05);compared with chronic cervicitis group and CIN group,the numbers of inflammatory cells and EOS infiltration of the patients in cervical cancer group were increased(P<0.05).The EOS in cervical cancer tissue was mainly distributed around the cancer nests;compared with CIN stage Ⅰ group,the numbers of EOS infiltration in CIN stage Ⅱ and CIN stage Ⅲ groups were increased(P<0.05);compared with CIN stage Ⅱ group,the number of EOS infiltration in CIN stage Ⅲ group was increased(P<0.05).The higher the malignancy degree of the tumor,the more EOS infiltration was observed,and the number of EOS infiltration was positively correlated with the invasion depth of cervical cancer(r=0.533 0,P<0.01).Conclusion:HPV infection and EOS infiltration play a role in promoting the and occurrence development of cervical precancerous lesions and cervical cancer.

Objective To investigate the epidemiological characteristics and mutation spectrum of monogenic diseases in Chinese population through a large-scale,multicenter carrier screening.Methods This study was conducted among a total of 33 104 participants(16 610 females)from 12 clinical centers across China.Carrier status for 223 genes was analyzed using high-throughput sequencing and different PCR methods.Results The overall combined carrier frequency was 55.58%for 197 autosomal genes and 1.84%for 26 X-linked genes in these participants.Among the 16 669 families,874 at-risk couples(5.24%)were identified.Specifically,584 couples(3.50%)were at risk for autosomal genes,306(1.84%)for X-linked genes,and 16 for both autosomal and X-linked genes.The most frequently detected autosomal at-risk genes included GJB2(autosomal recessive deafness type 1A,393 couples),HBA1/HBA2(α-thalassemia,36 couples),PAH(phenylketonuria,14 couples),and SMN1(spinal muscular atrophy,14 couples).The most frequently detected X-linked at-risk genes were G6PD(G6PD deficiency,236 couples),DMD(Duchenne muscular dystrophy,23 couples),and FMR1(fragile X syndrome,17 couples).After excluding GJB2 c.109G>A,the detection rate of at-risk couples was 3.91%(651/16 669),which was lowered to 1.72%(287/16 669)after further excluding G6PD.The theoretical incidence rate of severe monogenic birth defects was approximately 4.35‰(72.5/16 669).Screening for a battery of the top 22 most frequent genes in the at-risk couples could detect over 95%of at-risk couples,while screening for the top 54 genes further increased the detection rate to over 99%.Conclusion This study reveals the carrier frequencies of 223 monogenic genetic disorders in the Chinese population and provides evidence for carrier screening strategy development and panel design tailored to the Chinese population.In carrier testing,genetic counseling for specific genes or gene variants can be challenging,and the couples need to be informed of these difficulties before testing and provided with options for not screening these genes or gene variants.

ObjectiveThe human angiotensin converting enzyme2 （hACE2） transgenic mouse model was used to clarify the antiviral efficacy of BD-77 against a novel coronavirus SARS-CoV-2 and explore the action mechanism of BD-77 against SARS-CoV-2. MethodSARS-CoV-2 Omicron and Delta variant strains-infected VeroE6 cell models were established and administered with BD-77 to observe the antiviral effect of BD-77 in vitro. A kit was used to detect the effect of BD-77 in vitro on the binding of spike S protein of SARS-CoV-2 virus （Delta/Omicron） to angiotensin converting enzyme2 （ACE2）. Chromatography was adopted to detect the binding of BD-77 to the S protein and N protein of the novel coronavirus. hACE2 transgenic C57BL/6 mice were divided into a blank control group， SARS-CoV-2 infection group， BD-77 administration groups of 37.5 mg·kg^-1 and 75 mg·kg^-1， with eight mice in each group. The pneumonia model of SARS-CoV-2-infected hACE2 transgenic mice was built to observe the survival of the mice， detect the virus titer of the lung tissue of the mice， and observe the lesions in the lung tissue. ResultBD-77 had a certain inhibitory effect on Omicron and Delta variant strains in vitro， with median inhibitory concentration （IC₅₀） of 526.3 mg·L^-1 and 653.0 mg·L^-1， respectively. BD-77 had no significant inhibitory effect on the binding of the S protein of WT， Omicron， and Delta variant strains of SARS-CoV-2 to ACE2 and had no binding effect with the S protein and N protein of the novel coronavirus. No mice in the blank group died， while the mortality rate of SARS-CoV-2-infected mice was 75%. There was a large amount of virus replication in the lung tissue of the mice and large areas of inflammatory infiltration in the lung tissue and interstitium. Compared with the model group， BD-77 administration groups of 37.5 mg·kg^-1 and 75 mg·kg^-1 could reduce the mortality of mice， significantly lower the virus titer in the lung tissue of mice （P<0.05）， and improve lung lesions. ConclusionBD-77 demonstrated significant inhibitory effects against SARS-CoV-2 virus in vitro and in vivo. However， its mechanism of action did not involve direct inhibition of the virus itself or intervention in the virus-host binding process. This finding suggests that the mechanism of action of BD-77 needs to be thoroughly investigated and elucidated by further experiments.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period，9 035 strains of Gram-negative bacteria were collected from 51 hospitals，of which 7 895（87.4%）were Enterobacteriaceae and 1 140（12.6%）were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli（ n=4 510，49.9%）， Klebsiella pneumoniae（ n=2 340，25.9%）， Pseudomonas aeruginosa（ n=534，5.9%）， Acinetobacter baumannii complex（ n=405，4.5%）and Enterobacter cloacae（ n=327，3.6%）. The ESBLs-producing rates in Escherichia coli， Klebsiella pneumoniae and Proteus spp. were 47.1%（2 095/4 452），21.0%（427/2 033）and 41.1%（58/141），respectively. The prevalence of carbapenem-resistant Escherichia coli（CREC）and carbapenem-resistant Klebsiella pneumoniae（CRKP）were 1.3%（58/4 510）and 13.1%（307/2 340）；62.1%（36/58）and 9.8%（30/307）of CREC and CRKP were resistant to ceftazidime/avibactam combination，respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii（CRAB）complex was 59.5%（241/405），while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa（CRPA）was 18.4%（98/534）. There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions，with statistically significant differences in the prevalence of CRKP and CRPA（ χ2=20.489 and 20.252， P<0.001）. The prevalence of CREC，CRKP，CRPA，CRAB，ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals（ χ2=11.953，81.183，10.404，5.915，12.415 and 6.459， P<0.01 or <0.05），while the prevalence of CRPA was higher in economically developed regions（per capita GDP ≥ 92 059 Yuan）than that in economically less-developed regions（per capita GDP <92 059 Yuan）（ χ2=6.240， P=0.012）. Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend，and Escherichia coli is ranked in the top，while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different，and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.

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 summarize the clinical manifestations, experiences in diagnosis and treatment of arrhythmogenic cardiomyopathy (ACM) in children.Methods:A retrospective analysis of the clinical manifestations, laboratory tests, radiological features, treatment and follow-up results was conducted in 11 children diagnosed with ACM at the center of congenital heart disease, Beijing anzhen hospital from May 2010 to March 2022.Results:A total of 11 patients aged 2 to 16 years, including 5 males and 6 females were diagnosed with ACM. The clinical manifestations included decreased activity tolerance (7 patients), heart failure (4 patients), syncope or sudden death (3 patients), palpitation (3 patients), and chest tightness and pain (3 patients). Electrocardiogram showed right bundle branch block in 9 cases, paroxysmal ventricular tachycardia in 4 cases, frequent premature ventricular contraction in 4 cases, ventricular pre-excitation in 1 case, left bundle branch block in 1 case, and first degree atrioventricular block in 2 cases. Echocardiography showed enlargement of the right heart, widening of the right ventricular outflow tract, and thinning and bulging of the local wall of the right ventricle with reduced pulsation. Ventricular thrombosis was found in 2 cases. Six children underwent cardiac magnetic resonance imaging, which mainly showed severe enlargement of the right heart, thin free wall of the right ventricle, decreased right heart function, enhanced right ventricular myocardium, and formation of right ventricular aneurysm. Two children underwent myocardial biopsy examination and presented with typical pathological changes of ACM. Genetic tests in five patients revealed DSG2 gene mutation in 2 cases, PKP2 gene mutation in 2 cases, and MYH6 gene mutation in 1 case. All patients received anti heart failure treatment and antiarrhythmic drugs. Two children received anticoagulant treatment due to ventricular thrombosis. Radiofrequency ablation was performed in 2 patients. Glenn procedure was performed in 4 patients, and heart transplantation was performed in 1 patient due to progressive heart failure. The follow-up period ranged from 6 months to 12 years. Two cases died of right heart failure, 6 cases had different degrees of heart failure, 1 case had intermittent chest tightness and pain, and 2 cases were stable.Conclusions:ACM is a progressive genetic cardiomyopathy characterized by decreased activity tolerance, cardiac failure and arrhythmia in pediatric patients. The diagnosis is mainly based on clinical manifestations, electrocardiogram, cardiac imaging changes, and genetic testing. Early detection, diagnosis, and personalized treatment can improve the prognosis.

Objective:To explore the effect of emotional imagery desensitization therapy on posttraumatic stress disorder among school- age children with fracture, to alleviate the adverse psychological state of the children.Methods:By a randomized controlled trials, a total of 78 school- age children with fracture at the Affiliated Hospital of Jining Medical University from July 2021 to July 2023 were divided into experimental group and control group according to the admission time, with 39 cases in each group. Both groups carried out routine care, the control group was given routine psychological intervention, the experimental group implemented emotional imagery desensitization therapy. Before and after 3 months of intervention, the effects was assessed by Post-Traumatic Stress Disorder Self-rating Scale (PTSD-SS) and Medical Coping Modes Questionnaire (MCMQ), respectively.Results:During the research process, there were 2 cases of dropout in the control group due to disconnection, and 4 cases in the experimental group due to disconnection and voluntary withdrawal. 37 children in the control group [20 males and 17 females, age (9.27 ± 1.62) years], and 35 children in the experimental group [21 males and 14 females, age (9.57 ± 1.63) years] completed the intervention. Before intervention, the difference of PTSD-SS and MCMQ scores between two groups was no statistically significant (all P>0.05). After intervention, the subjective assessment, re-experiencing, avoidance symptoms, hypervigilance, functional impairment factor scores and total PTSD-SS scores were (1.51 ± 1.06), (10.74 ± 3.30), (10.86 ± 2.93), (11.94 ± 3.18), (2.31 ± 1.30), (37.37 ± 6.37) in the experimental group, lower than in the control group (2.08 ± 0.80), (12.92 ± 3.63), (12.73 ± 2.99), (14.65 ± 4.23), (2.97 ± 0.87), (45.35 ± 5.86), the differences were statistically significant ( t=2.53-5.54, all P<0.05). After intervention, the confrontation subscale scores were (23.49 ± 2.48), higher than in the control group (21.89 ± 2.38), the avoidance, acceptance- resignation subscale were (10.31 ± 1.89) and (6.83 ± 1.98), lower than in the control group (11.57 ± 1.79) and (7.86 ± 2.12), the differences were statistically significant ( t=2.79, 2.89, 2.14, all P<0.05). Conclusions:Emotional imagery desensitization therapy can effectively alleviate post- traumatic stress disorder and promote positive coping mode in school-age children with fracture.
