Carbapenem-resistant Klebsiella pneumoniae(CRKP),as a superbug pathogen,has become a critical global public health threat,with significantly increased detection rates especially in ICU and immunocompromised patients.Traditional antibiotics are progressively losing efficacy,and CRKP's antibiotic resistance spectrum continues to expand,presenting enormous clinical treatment challenges.Bacteriophages,as viruses specifically infecting bacteria,have emerged as a new therapeutic strategy for alternative or complementary antibiotic treatment due to their strong lytic capabilities,excellent biofilm penetration,low side effects,and ability to synergize with antibiotics.This article systematically reviews the epidemiology and resistance mechanisms of CRKP,principles and mechanisms of bacteriophage therapy,research progress(including in vitro experiments,animal models,and clinical applications),combined therapies,and their advantages and challenges.By incorporating the latest research,the article also proposes future development directions,including constructing genetically engineered bacteriophages,designing"intelligent bacteriophages"through synthetic biology,and establishing clinical regulatory systems.Bacteriophage therapy offers a potential breakthrough in combating CRKP,but its standardization,broad-spectrum applicability,and clinical translation pathways still require in-depth exploration and standardization.

Objective:To investigate the incidence of thyroid dysfunction in patients with chronic kidney disease and analyze the influencing factors.Methods:One hundred and ninety-eight patients with chronic kidney disease who were treated in Chronic Disease Management Department of the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine from Apr. 2021 to Apr. 2022 were selected, including 71 patients with abnormal thyroid function and 127 patients with normal thyroid function. The differences in TT3, FT3, TT4, FT4, and TSH between patients with abnormal thyroid function and those with normal thyroid function were analyzed. At the same time, the abnormal thyroid function of patients with different clinical characteristics and the influencing factors were analyzed. The intergroup differences were analyzed using t-test or χ2-test, and the influencing factors were analyzed using logistic regression analysis. Results:In one hundred and ninety-eight patients with chronic kidney disease, thyroid function abnormality occurred in 71 patients (35.86%), including two or more abnormal thyroid function indicators in 35 patients (49.30%). The total triiodothyronine (TT3), free triiodothyronine (FT3), total thyroxine (TT4) and free thyroxine (FT4) in patients with abnormal thyroid function were (1.02 ± 0.29) nmol/mL, (3.03 ± 0.88) pmol/L, (77.93 ± 20.02) nmol/mL and (11.02 ± 1.95) pmol/L respectively, which was significantly lower in patients with normal thyroid function (1.32±0.25) nmol/mL, (4.20±0.92) pmol/L, (93.30±19.28) nmol/mL and (13.54±1.82) pmol/ ( P<0.05), while thyroid stimulating hormone (TSH) was (3.14 ± 0.96) mIU/L, which was significantly higher than that in patients with normal thyroid function (1.84±0.89) mIU/L ( P<0.05). The incidence of thyroid dysfunction in female patients was 50.59% (43/85), It was significantly higher than 24.78% (28/113) of male patients (P <0.05) ; The incidence of thyroid dysfunction in patients aged 60 years was 49.55% (55/111), It was significantly higher than 18.39% (16/87) of the patients aged <60 years ( P<0.05) ; The incidence of thyroid dysfunction in patients with 1-year duration of disease was 71.43% (30/42), It was significantly higher than 25.28% (41/156) of patients with a course of disease <1 year ( P<0.05) ; The incidence of thyroid dysfunction in patients with clinical stage G 4 to 5 was 50.62% (41/81), It was significantly higher than 25.64% (30/117) of patients in G1~3 stages ( P<0.05) ; The incidence of thyroid dysfunction in patients with diabetes was 74.36% (29/39), This was significantly higher than 26.42% (42/159) in patients without diabetes mellitus ( P<0.05). Logistic regression analysis showed that gender, age, course of disease and clinical stage were the influencing factors of thyroid dysfunction in patients with chronic kidney disease ( P<0.05) . Conclusion:A high proportion of patients with chronic kidney disease have abnormal thyroid function, which is affected by the patient's sex, age, course of disease and clinical stage,clinical attention should be paid to targeted intervention to prevent the incidence of thyroid dysfunction in chronic kidney disease population.

Transient perivascular inflammation of the carotid artery (TIPIC) syndrome is a relatively rare disease, and ultrasound is the first screening method for initial diagnosis of the disease. Contrast-enhanced ultrasound (CEUS) has unique advantages in the follow-up of patients with TIPIC syndrome. This paper reports a patient with TIPIC syndrome who was treated with acute left neck pain. The inflammation was significantly relieved and subsided after treatment with non-steroidal anti-inflammatory drugs. The ultrasound changes of carotid artery lesions in this patient during follow-up were analyzed, and the application value of CEUS in the follow-up diagnosis of this disease was summarized, in the hope of providing clinical reference.

Objective To summarize and analyze the application of regional citrate anticoagulation (RCA) in patients undergoing continuous renal replacement therapy (CRRT) using a scoping review methodology. Methods Following the scoping review methodology, a systematic search was conducted in domestic and international databases, including CNKI, Wanfang Data, Cochrane Library, PubMed, and Embase for literature related to RCA in CRRT patients. The search was limited from the inception of the databases to August 10, 2023. Included studies were screened, summarized, and analyzed. Results A total of 19 articles were included in this study, comprising 8 randomized controlled trials, 8 cohort studies, 2 case-control studies, and 1 cross-sectional survey. Anticoagulation methods for CRRT primarily included unfractionated heparin, low-molecular-weight heparin, thrombin inhibitors, nafamostat, and RCA. Compared to other anticoagulation methods, RCA exhibited advantages in lower bleeding risk and longer filter lifespan. Calcium ion monitoring during RCA application predominantly relies on the empirical trial-and-error approach. Major complications associated with RCA include citrate accumulation, acid-base imbalance, and ion metabolic disorders. For patients with high bleeding risk, hypercalcemia, and sepsis, RCA may confer greater benefits during CRRT. Conclusion RCA has gradually emerged as a preferred anticoagulation method for CRRT patients, offering advantages in extending filter lifespan and reducing bleeding risk. Future research should focus on calcium ion monitoring during RCA, enhancing safety and efficacy through targeted infusion systems, and further exploring the immunomodulatory effects of RCA and its mechanisms related to high inflammatory factor clearance rates.

Objective:
To explore the relationship between maternal emotional symptoms and emotional and behavioral problems (EBPs) of preschool offspring, and to provide reference for prevention and intervention of emotional and behavior problems in preschool children.
Methods:
A total of 4 100 preschool children aged 3-6 in Fuyang City were enrolled by stratified cluster sampling method in June 2021. The Strengths and Difficulties Questionnaire (SDQ) and Depression Anxiety and Stress Scale (DASS-21) were used to investigate preschool children s EBPs and maternal emotional symptoms, respectively.
Results:
The detection rates of preschool children s emotional symptoms, conduct problems, hyperactivity, peer interaction problems, prosocial behavior and difficulty scores were 15.7%, 17.4%, 20.0%, 32.3%, 15.1% and 15.8%, respectively. The detection rates of mother s depression, anxiety and stress symptoms were 7.9%, 12.7% and 4.8%, respectively. Multivariate Logistic regression analysis showed that, compared with children of mothers with no depression, anxiety and stress symptoms, offspring of mothers reported depression, anxiety and stress symptoms had significantly higher risks of emotional symptoms, conduct problems, hyperactivity, peer problems and total difficulties ( OR=1.76-6.35, P <0.01). Maternal emotional symptoms had the most significant effect on children s emotional symptoms, and there was no significant correlation between maternal stress symptoms and children s prosocial behavior ( OR=1.40, P >0.05). There was no significant gender difference in the relationship between maternal emotional symptoms and children s emotional and behavioral problems ( ROR=0.73-1.07, P >0.05). For only children whose mothers reported stress symptoms showed a higher risk of emotional and behavior problems than non singleton children ( ROR=2.03, P <0.05).
Conclusion
Maternal emotional symptoms are related to preschool children s emotional and behavioral problems. Early identification and intervention of mother s negative emotional symptoms, are beneficial to the prevention of preschool children s emotional and behavioral problems.

BACKGROUND:
China bears the biggest atrial fibrillation (AF) burden in the world. However, little is known about the incidence and predictors of AF. This study aimed to investigate the current incidence of AF and its electrocardiographic (ECG) predictors in general community individuals aged over 60 years in China.
METHODS:
This was a prospective cohort study, recruiting subjects who were aged over 60 years and underwent annual health checkups from April to July 2015 in four community health centers in Songjiang District, Shanghai, China. The subjects were then followed up from 2015 to 2019 annually. Data on sociodemographic characteristics, medical history, and the resting 12-lead ECG were collected. Kaplan-Meier curve was used for showing the trends in AF incidence and calculating the predictors of AF. Associations of ECG abnormalities and AF incidence were examined using Cox proportional hazard models.
RESULTS:
This study recruited 18,738 subjects, and 351 (1.87%) developed AF. The overall incidence rate of AF was 5.2/1000 person-years during an observation period of 67,704 person-years. Multivariable Cox regression analysis indicated age (hazard ratio [HR], 1.07; 95% confidence interval [CI]: 1.06-1.09; P < 0.001), male (HR, 1.30; 95% CI: 1.05-1.62; P = 0.018), a history of hypertension (HR, 1.55; 95% CI: 1.23-1.95; P < 0.001), a history of cardiac diseases (HR, 3.23; 95% CI: 2.34-4.45; P < 0.001), atrial premature complex (APC) (HR, 2.82; 95% CI: 2.17-3.68; P < 0.001), atrial flutter (HR, 18.68; 95% CI: 7.37-47.31; P < 0.001), junctional premature complex (JPC) (HR, 3.57; 95% CI: 1.59-8.02; P = 0.002), junctional rhythm (HR, 18.24; 95% CI: 5.83-57.07; P < 0.001), ventricular premature complex (VPC) (HR, 1.76; 95% CI: 1.13-2.75, P = 0.012), short PR interval (HR, 5.49; 95% CI: 1.36-22.19; P = 0.017), right atrial enlargement (HR, 6.22; 95% CI: 1.54-25.14; P = 0.010), and pacing rhythm (HR, 3.99; 95% CI: 1.57-10.14; P = 0.004) were independently associated with the incidence of AF.
CONCLUSIONS
The present incidence of AF was 5.2/1000 person-years in the studied population aged over 60 years in China. Among various ECG abnormalities, only APC, atrial flutter, JPC, junctional rhythm, short PR interval, VPC, right atrial enlargement, and pacing rhythm were independently associated with AF incidence.

BACKGROUND:
Glutamine synthetase (GS) and arginase 1 (Arg1) are widely used pathological markers that discriminate hepatocellular carcinoma (HCC) from intrahepatic cholangiocarcinoma; however, their clinical significance in HCC remains unclear.
METHODS:
We retrospectively analyzed 431 HCC patients: 251 received hepatectomy alone, and the other 180 received sorafenib as adjuvant treatment after hepatectomy. Expression of GS and Arg1 in tumor specimens was evaluated using immunostaining. mRNA sequencing and immunostaining to detect progenitor markers (cytokeratin 19 [CK19] and epithelial cell adhesion molecule [EpCAM]) and mutant TP53 were also conducted.
RESULTS:
Up to 72.4% (312/431) of HCC tumors were GS positive (GS+). Of the patients receiving hepatectomy alone, GS negative (GS-) patients had significantly better overall survival (OS) and recurrence-free survival (RFS) than GS+ patients; negative expression of Arg1, which is exclusively expressed in GS- hepatocytes in the healthy liver, had a negative effect on prognosis. Of the patients with a high risk of recurrence who received additional sorafenib treatment, GS- patients tended to have better RFS than GS+ patients, regardless of the expression status of Arg1. GS+ HCC tumors exhibit many features of the established proliferation molecular stratification subtype, including poor differentiation, high alpha-fetoprotein levels, increased progenitor tumor cells, TP53 mutation, and upregulation of multiple tumor-related signaling pathways.
CONCLUSIONS
GS- HCC patients have a better prognosis and are more likely to benefit from sorafenib treatment after hepatectomy. Immunostaining of GS may provide a simple and applicable approach for HCC molecular stratification to predict prognosis and guide targeted therapy.

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.
