ABSTRACT
Background and aim: Spontaneous rupture of hepatocellular carcinoma (HCC) is a life-threatening complication, and patients who experience it are formally assigned to stage T4 in the TNM system, while many clinicians informally assign them to stage C in the more widely used Barcelona Clinic Liver Cancer (BCLC) system. The present study explored whether these re-staging practices are appropriate for HCC patients who suffer tumor rupture. Methods: We retrospectively reviewed the records of 1952 HCC patients who underwent hepatic resection at our hospital between January 2017 and June 2021. We compared recurrence-free and overall survival between 143 patients who had BCLC stage A or B disease at the time of spontaneous rupture and 449 patients who had BCLC stage C disease without rupture. Results: Overall survival rate was significantly higher among the 143 patients (1, 3, 5-year survival rate was 80.3%, 60.4%, 51.4%) with rupture than among the 449 (1, 3, 5-year survival rate was 69.5%, 41.5%, 32.4%) with BCLC stage C disease (hazard ratio 1.65, 95% confidence interval 1.29 to 2.12). The two groups had similar recurrence-free survival (hazard ratio 1.19, 95% confidence interval 0.92 to 1.53), but most patients with rupture were able to receive interventional and potentially curative treatments after recurrence, whereas most patients in BCLC stage C received interventional or supportive care. Similar results were obtained after propensity score matching. Conclusion: HCC patients who experience spontaneous rupture tumor while in BCLC stage A or B have better prognosis than patients in BCLC stage C without rupture. Our results suggest that HCC patients who suffer rupture in BCLC stage A or B should not be assigned to BCLC stage C.
ABSTRACT
Worldwide, as the population age, osteoporosis is becoming increasingly common, and osteoporotic fractures have a significant economic burden. Postmenopausal women are the most susceptible to developing osteoporosis and the most critical time to prevent it is during the perimenopausal and early menopausal years. In this regard, we hypothesize rational combination of acupuncture and Traditional Chinese Medicine (TCM) in the form of herbal extract could prevent osteoporosis in women. Estrogen deficiency during menopause causes low-level inflammation that stimulates the formation of osteoclasts, the bone-resorbing cells, and simultaneously inhibits the viability and function of osteoblasts, the bone-forming cells. The most potent inflammatory cytokine in skeletal homeostasis is the receptor activator of nuclear factor kappa B ligand (RANKL) that stimulates osteoclast function. Conversely, the canonical Wnt pathway is essential for osteoblastogenesis and bone formation, and estrogen deficiency leads to diminished functioning of this pathway. TCM and acupuncture could target the RANKL and the Wnt pathway in favorable ways to prevent the accelerated bone loss experienced during the early menopausal stage and promote the gain in bone mass in postmenopausal women. In this review, we propose a rational combination of specific TCM and acupuncture targeting those signaling molecules/pathways by the drugs that are in clinical use for the treatment of postmenopausal osteoporosis. Our rational approach revealed that Danshen (Radix Salviae Miltiorrhizae) could exert a synergistic effect with acupuncture. We then propose a translational path for developing the putative combination in women with postmenopausal osteoporosis to curtail the risk of osteoporotic fractures.

ABSTRACT
Based on UPLC-Q-orbitrap-MS and biological network analysis tools, the mechanism of Xihuang Pill in improving hyperplasia of mammary glands was systematically analyzed. The rat model of hyperplasia of mammary glands was established by intramuscular injection of estradiol benzoate and progesterone. LC-MS tissue metabolomics was used to explore the key metabolites and metabolic pathways of Xihuang Pill in improving hyperplasia of mammary glands in rat. The network analysis of the key metabolites regulated by Xihuang Pill was carried out by integrating biological network analysis tools, focusing on the key metabolic pathways, and exploring the potential targets of Xihuang Pill to improve hyperplasia of mammary glands. Compared with the control group, there were significant differences in the content of 49 differential metabolites in the tissues of the model group (P < 0.05). Xihuang Pills could significantly call back 17 metabolites such as L-alanine, threonine, indole-3-carboxylic aldehyde, lysine, arginine, alanylleucine, glycyltyrosine, γ-glutamyl leucine, vitamin B3, serine leucine, threonine leucine, isoleucine glutamic acid, γ-glutamyl tyrosine, decanoyl-L-carnitine, uric acid, leucylleucine, S-adenosyl-methionine. Further network analysis and literature research on the key metabolites regulated by Xihuang Pills showed that the AGE-RAGE signaling pathway may be one of the important pathways for Xihuang Pills to improve hyperplasia of mammary glands. STAT3, MAPK1, EGFR, CASP3, CASP8, PRKCA and JUN in the AGE-RAGE signaling pathway may be potential targets for Xihuang Pills to improve hyperplasia of mammary glands. The animal experiment operations involved in this paper follow the provisions of the Animal Ethics Committee of Gansu University of Traditional Chinese Medicine and pass the ethical review of animal experiments (approval number: 2022-705).
ABSTRACT
Objective:To investigate the expression, prognostic value and mechanism of MCM10 in hepatocellular carcinoma (LIHC).Methods:The transcriptome and clinical data of hepatocellular carcinoma were obtained from The Cancer Genome Atlas database, and the rank sum test was used to analyze the expression level of MCM10 in tumor tissues and adjacent tissues. Cox regression analysis was used to analyze the relationship between MCM10 expression level and the survival prognosis of patients with hepatocellular carcinoma. Gene set enrichment analysis (GSEA) was utilized for pathway enrichment analysis between MCM10 high and low group gene expression profiles. The effect of MCM10 knockdown on the proliferation of HepG2 cells was determined by cell counting kit-8 (CCK-8) cell viability assay. The effect of MCM10 knockdown on the expression of G1/S-specific cyclin D1 was detected by Western blot.Results:The expression value of MCM10 in hepatocellular carcinoma was 0.709±0.595, and that in adjacent tissues was 0.077±0.094 ( P<0.0 001). Cox regression analysis showed that high expression of MCM10 was a risk factor and prognostic predictor of overall survival ( HR=1.32, 95% CI: 1.19~1.48) and disease-specific survival ( HR=1.40, 95% CI: 1.22~1.61) in LIHC. GSEA analysis showed that the differentially expressed genes were mainly enriched in cell cycle, p53 signaling pathway and positive regulation of G1-S phase transition, et al. CCK-8 assay showed that MCM10 knockdown could inhibit the proliferation of HepG2 cells. Western blot analysis further confirmed that knockdown of MCM10 expression inhibited the expression of cyclin D1 in HepG2 cells. Conclusions:MCM10 is a risk factor for the prognosis of patients with hepatocellular carcinoma, which can promote the proliferation of hepatoma cells through cyclin D1.
ABSTRACT
Spatial environment includes multiple scales, which can be specifically divided into operable near-scale figural space, navigable space consisting of single-viewpoint space and environmental space, and large-scale geographic space. It is very important for human and other animal’s daily life to distinguish the spatial environment at different scales. The representation of spatial scale is related to its corresponding functional requirements. The parietal lobe is responsible for the representation of near-scale space. Navigable spatial representation in the hippocampus and cerebral cortex shows a “coarse to fine” gradient along the posterior to anterior axis. However, the scale representation of abstract social space shows a dichotomy. Future research should focus on temporal dynamics of spatial scale representation and the influence of spatial scale on the format of the cognitive map.
ABSTRACT
The brain’s neural circuits consist of a large number of highly unstable networks. Despite the existence of many internal and external factors that continuously disturb the balance, our brains employ an array of homeostatic mechanisms that allow neurons or neural circuits to sense how active they are, and when they deviate from a target value, whereby a force must be generated to move neuronal activity back toward this target. Sleep is one of the well-known physiological states in the regulation of homeostasis. Sleep pressure increases during wakefulness and decreases during sleep. When sleep is lost (e.g., sleep deprivation), this loss is compensated by extending or strengthening subsequent sleep. These phenomena are known as sleep homeostasis. The dysregulation of sleep homeostasis accompanies brain-related diseases such as schizophrenia, bipolar disorder, major depressive disorder, and autism spectrum disorder. More importantly, it can significantly undermine the basis of traditional sleep hygiene practices for these diseases. Therefore, clarifying the mechanisms of sleep homeostasis is important for therapy, but it remains an unsolved mystery. In addition to pharmacological treatment, non-invasive brain stimulation has become one of the most promising tools for clinical treatment in recent years due to its low cost, portability and low incidence of side effects. In order to promote relevant technologies, this review will focus on the electrophysiological mechanisms of sleep homeostasis. We first discuss the electrophysiological marker of sleep homeostasis, slow-wave activity, then move to the neuronal firing rates, finally discuss more aspects of sleep homeostasis, including differences in brain area, sleep stages, learning and individual differences.

It is recommended that schools should appropriately increase after school ES to promote physical fitness of students.
ABSTRACT
Tendon-bone healing is a complex biological process. Multiple signaling pathways are involved in tendon-bone healing， including transforming growth factor-β signaling pathway， bone morphogenetic protein signaling pathway， Wnt signaling pathway， fibroblast growth factor signaling pathway and nuclear transcription factor-κB signaling pathway. This paper summarizes the research status of traditional Chinese medicine regulating related signaling pathways to promote tendon-bone healing. It is found that a variety of traditional Chinese medicine monomers or herbal extracts （such as baicalein， icariin， total flavonoids of Drynaria fortunei， parthenolide， total saponins of Panax notoginseng， etc.） and traditional Chinese medicine compounds （such as Taohong siwu decoction， Liuwei dihuang pill， Xujin jiegu liquid， etc.） can promote bone formation， anti-inflammatory， anti-oxidation， by regulating the above signaling pathways， thereby effectively promoting tendon-bone healing.
ABSTRACT
The analysis of ammonia nitrogen in real water samples is challenging due to matrix interferences and difficulties for rapid on-site analysis.On the basis of the standard method,i.e.water quality-determination of ammonia nitrogen-salicylic acid spectrophotometry(HJ 536-2009),a simple device for online detecting ammonia nitrogen was developed using a sequential injection analysis(SIA)system in this work.The ammonia nitrogen transformation system,color reaction system,and detection system were built in compatible with the SIA system,respectively.In particular,the detection system was assembled by employing light-emitting diode as the light source,photodiode as the detector,and polyvinylchloride tube as the cuvette,thus significantly reducing the volume,energy consumption and fabricating cost of the detection system.As a result,the accurate analysis of ammonia nitrogen in complex water samples was achieved.A quantitative detection of ammonia nitrogen in water sample was obtained in 12 min,along with linear range extending to 1000 μmol/L,precisions(Relative standard deviation,RSD)of 4.3%(C=10 μmol/L,n=7)and 4.2%(C=500 μmol/L,n=7),and limit of detection(LOD)of 0.65 μmol/L(S/N=3,n=7).The results of interfering experiments showed that the detection of ammonia nitrogen by the developed device was not interfered by the common coexisting ions and components,therefore the environmental water could be directly analyzed,such as reservoir water,domestic sewage,sea water and leachate of waste landfill.The analytical results were consistent with those obtained by the environmental protection standard method(Water quality determination of ammonia nitrogen-salicylic acid spectrophotometry,HJ 536-2009).In addition,the spiking recoveries were in the range of 92.3%-98.1%,further confirming the accuracy and practicality of the developed device.
ABSTRACT
Important forensic diagnostic indicators of sudden death in coronary atherosclerotic heart dis-ease,such as acute or chronic myocardial ischemic changes,sometimes make it difficult to locate the ischemic site due to the short death process,the lack of tissue reaction time.In some cases,the de-ceased died of sudden death on the first-episode,resulting in difficulty for medical examiners to make an accurate diagnosis.However,clinical studies on coronary instability plaque revealed the key role of coronary spasm and thrombosis caused by their lesions in sudden coronary death process.This paper mainly summarizes the pathological characteristics of unstable coronary plaque based on clinical medi-cal research,including plaque rupture,plaque erosion and calcified nodules,as well as the influencing factors leading to plaque instability,and briefly describes the research progress and technique of the atherosclerotic plaques,in order to improve the study on the mechanism of sudden coronary death and improve the accuracy of the forensic diagnosis of sudden coronary death by diagnosing different patho-logic states of coronary atherosclerotic plaques.
ABSTRACT
Objective To analyze the metabolomics characteristics of chronic atrophic gastritis(CAG)patients with liver-stomach qi stagnation and spleen-stomach weakness syndromes based on non-targeted metabolomics technology,and to identify the serum differentiated metabolites related to traditional Chinese medicine(TCM)syndrome of CAG patients,so as to provide a reference for the objectification of syndrome differentiation.Methods Sixty patients with CAG were included,including 30 cases of liver-stomach qi stagnation syndrome and 30 cases of spleen-stomach weakness syndrome.Fasting blood of 5 mL was collected from the cubital vein of patients in the two groups,and the serum levels of metabolites were detected by ultra-high-performance liquid chromatography-mass spectrometry(UPLC-MS)methods.The principal component analysis(PCA),orthogonal partial least squares-discriminant analysis(OPLS-DA),and cluster analysis were used to screen the differentiated metabolites of CAG patients with liver-stomach qi stagnation syndrome and spleen-stomach weakness syndrome.Finally,metabolite pathway analysis was performed for the obtained differentiated metabolites using the KEGG database.Results The results for the screening of differentiated metabolites showed that significant differences of amino acid derivatives and small peptide metabolites were presented between CAG patients with liver-stomach qi stagnation syndrome and CAG patients with spleen-stomach weakness syndrome.The amino acid derivatives consisted of N-acetylglycine,histamine,O-phosphoserine,selenomethylselenocysteine,and methyl-tyrosine.And the small peptide metabolites consisted of tyrosine-leucine-phenylalanine,histidine-alanine-glutamate-lysine,L-asparagine-L-proline-L-serine,and L-isoleucine-L-isoleucine.Conclusion Differences in amino acid metabolism exist between CAG patients with liver-stomach qi stagnation syndrome and those with spleen-stomach weakness syndrome,and metabolites such as N-acetylglycine,intermethyltyrosine,and O-phosphoserine may be the potential biomarkers for distinguishing liver-stomach qi stagnation syndrome from spleen-stomach weakness syndrome in CAG patients.
ABSTRACT
Objective To compare the clinical application value of medical glue and a new-type medical anchor positioning needle in thoracoscopic resection of pulmonary nodules.Methods A total of 182 patients with pulmonary nodules,who received video-assisted thoracic surgery(VATS)at the Department of Thoracic Surgery of Affiliated Hospital of Shaoxing University of China between January 2020 and December 2022,were enrolled in this study.Preoperative CT-guided localization of the pulmonary nodule was performed in all patients,including medical glue positioning in 89 patients(medical glue group)and anchor needle positioning in 93 patients(anchor needle group).The incidences of pneumothorax and bleeding,the time spent for positioning,the interval between localization and operation,the time spent for operation,and the radiation dose during localization process were recorded and the data were statistically analyzed.Results The success rate of positioning was 100％(93/93)in the anchor needle group and 96.7％(86/89)in the medical glue group.There was no statistically significant difference between the two groups(P>0.05).The incidence of bleeding was 31.2％(29/93)in the anchor needle group and 15.7％(14/89)in the medical glue group,and the difference between the two groups was statistically significant(P<0.05).The incidence of pneumothorax was 30.1％(28/93)in the anchor needle group and 20.2％(18/89)in the medical glue group,and there was no significant difference between the two groups(P>0.05).No statistically significant difference in the time spent for operation existed between the two groups(P>0.05).The time spent for positioning and the interval between localization and operation in the medical glue group were longer than those in the anchor needle group,and the radiation dose in the medical glue group was higher than that in the anchor needle group,and the differences between the two groups were statistically significant(P<0.05).Conclusion For the preoperative localization of ground glass opacity(GGO)or solitary pulmonary nodule(SPN),both medical glue positioning method and anchor needle positioning method have high clinical application value.The clinical and interventional physicians should adopt appropriate positioning method according to the patient's condition.
ABSTRACT
Objective To evaluate the short-term clinical effect of arthroscopic repair of rotator cuff injury with all-suture anchor using a prospective and single-cohort clinical trial.Methods Twenty-five patients with rotator cuff injuries(1.5 cm<tear size<6 cm)and admitted to the Department of Sports Medicine and Ambulatory Surgery Centre of Jiangsu Provincial Subei People's Hospital between July and September 2022 were used as the study subjects.Two cases were excluded for not meeting the in-clusion criteria,while another one was withdrawn halfway due to inconvenience of follow-up.Finally,22 patients were included in the study,consisting of 8 males and 14 females,with the average age of 59.1±10.9 years and rotator cuff tear size of 3.2±1.2 cm of 10 left and 12 right shoulders.Be-fore as well as 3 and 6 months after operation,all patients were evaluated using the pain visual ana-logue scale(VAS),the American Shoulder and Elbow Surgeons(ASES)score,Constant-Murley Shoul-der Functional(Constant)Score,Simple Shoulder Test(SST),bilateral shoulder abduction muscle strength ratio(affected/healthy),and mobility of the affected shoulder joint.Six months after operation,the healing of rotator cuff and the formation of cyst around the all-suture anchor were evaluated by us-ing the magnetic resonance imaging(MRI).According to whether there was cysts around the all-suture anchor,the patients were divided into the cyst group and the cyst-free group.Their age,sex,the side affected,trauma history,course time,tear size and operation time of the two groups were com-pared and analyzed to find the correlated factors.The average VAS,ASES and Constant scores,and the range of motion of the affected shoulder joint and the healing grade of rotator cuff were compared between the two groups 6 months after operation.Results Twenty-two patients were granted 6.2±0.3 months of follow-up after surgery.Three and six months after the operation,their average VAS scores(1.3±1.2 and 0.7±0.4),ASES scores(79.7±12.3 and 88.9±6.5),Constant scores(65.4±12.4 and 73.7±9.6),SST scores(7.6±0.2 and 10.5±0.2)and bilateral shoulder abductor muscle strength ratio(affected side/healthy side)(71.3±9.6 and 90.3±5.9)were significantly higher than the values before the opration(4.2±1.1,51.5±11.2,46.2±12.8,3.5±0.3 and 21.9±15.8),respec-tively(P<0.05).There were also significant differences in the range of motion of shoulder joint 3 months and 6 months after surgery(P<0.05).Postoperative MRI revealed 1 patient with rotator cuff re-tear.There was significant difference in age between the cyst group and the cyst free group(P<0.05).However,there was no significant difference in VAS score,ASES score,Constant score,range of mo-tion of shoulder joint and healing grade of rotator cuff between the two groups 6 months after surgery(P>0.05).Conclusion Arthroscopic rotator cuff repair with all-suture anchor is feasible and safe,and has good short-term clinical effect.
ABSTRACT
Objective To compare the efficacy of TightRope loop plate and Endobutton plate in the treatment of acromioclavicular joint dislocation.Methods A retrospective analysis was conducted on 94 patients with acromioclavicular joint dislocation who were treated at this center from March 2021 to February 2023.They were divided into two groups based on different admission date.The Group E(n =47)received Endobutton plate treatment between March 2021 and February 2022,while the Group T(n =47)received TightRope loop plate treatment between March 2022 and February 2023.At the last follow-up,the perioperative indicators,Visual Analogue Scale(VAS),Constant-Murley shoulder joint function scores,and surgical complications were compared between the two groups.Results The surgical time,intraoperative bleeding,incision length,and VAS scores at 7 days after surgery in the Group T were shorter or lower than those in the Group E(P<0.05).There were no statistical differences in the incidence of perioperative nerve injury,internal fixation displacement,clavicle fracture,vascular injury,and infection between the two groups(P>0.05).The subjective and objective scores of Constant-Murley shoulder joint function in both groups at9 months after surgery showed significant improvement compared to preoperative scores(all P =0.000).There was no significant difference in the subjective and objective scores of Constant-Murley shoulder joint function between the two groups at 9 months after surgery(P>0.05).Conclusions The treatment of acromioclavicular joint dislocation with TightRope loop plate ot or Endobutton plate has a significant effect and can effectively improve shoulder joint function.Compared with Endobutton plate,use of TightRope loop plate has minor surgical trauma,less bleeding,and significantly reduced postoperative pain,being more conducive to early functional exercise for patients.
ABSTRACT
Objective:To evaluate the effect of combining contralateral high-frequency transcranial magnetic stimulation (rTMS) with biofeedback-controlled empty swallowing training on dysphagia among stroke survivors.Methods:Eighty dysphagic stroke survivors were divided at random into a control group, a biofeedback group, an rTMS group and a combined treatment group, each of 20. In addition to routine dysphagia rehabilitation, the biofeedback group and the rTMS group received empty swallowing training based on biofeedback or high-frequency rTMS applied to the healthy motor cortex as appropriate. The combined treatment group was given both. The treatment was administered once daily, 5 days a week for 3 consecutive weeks. Before and after the treatment, all of the subjects′ swallowing was evaluated using the penetration aspiration scale (PAS), functional oral intake scale (FOIS) and a standardized swallowing assessment (SSA). The latency and amplitude of the mylohyoid muscle′s motor evoked potentials (MEPs) were also recorded before and after the treatment.Results:After the treatment, significant improvement was observed in the average PAS, FOIS and SSA scores as well as in the latency and amplitude of the MEPs in the four groups. The average results in the combined treatment group were significantly better than in the other 3 groups. The latency of the mylohyoid muscle′s MEP was significantly shorter in the combined group than in the control and biofeedback groups on average, while the amplitude was significantly greater than in the control group.Conclusion:Combining contralateral high frequency rTMS with empty swallowing training based on biofeedback can better improve the swallowing of dysphagic stroke survivors.

【Objective】 To analyze the association between preschool children′s emotional regulation ability and parents′ participation in accompanying picture book reading, in order to provide theoretical reference for improving children′s emotional regulation abilility. 【Methods】 From September to November 2022, preschool children aged 3 - 6 years from Guangfeng County, Yukan County, Wannian County, Yanshan County and Wuyuan County were selected by random cluster stratified sampling method. Mann-Whitney U test or Kruskal-Wallis H test were used to analyze the correlation of different levels of children′s emotional control ability with different demographic characteristics as well as parents′ participation in children′s picture book reading. Multivariate Logistic regression model was used to analyze the correlation between parents′ involvement in picture book reading and children′s emotional control ability. 【Results】 Finally 848 valid questionnaires were collected.The average age of children was (4.33±0.95)years old,with 432 boys and 416 girls. Multivariate Logistic regression analysis showed that the temperament control ability(>P75) of preschool children was positively correlated with mother being the main accompanying caregiver (OR=4.17, 95%CI: 2.13 - 8.17), and negatively correlated with father being the main accompanying caregiver (OR=0.38, 95%CI: 0.21 - 0.70) or both parents being the main accompanying caregivers (OR=0.14, 95%CI: 0.07 - 0.28)(P<0.05). The social confidence (father as the main caregiver OR=3.53, 95%CI:1.62 - 7.66; mother as the main caregiver OR=3.52, 95%CI: 1.66 - 7.45) and anxiety control abilities(father as the main caregiver OR=4.32, 95%CI: 1.85 - 10.09; mother as the main caregiver OR=3.39, 95%CI: 1.49 - 7.73) of preschool children were positively correlated with the type of accompanying caregiver(P<0.05). Additionally, the anxiety control ability (>P75) of preschool children was negatively correlated with father′s accompanying frequency (sometimes OR=0.09, 95%CI: 0.03 - 0.28; often OR=0.19, 95%CI: 0.06 - 0.60) and mother′s accompanying duration (<1h/d OR=0.33, 95%CI: 0.12 - 0.91) (P<0.05). 【Conclusions】 The frequency and duration of accompanying reading by father or mother are correlated with the emotional regulation ability of preschool children. Parents can moderately participate in picture book reading to promote the development of preschool children′s emotional control ability.
ABSTRACT
【Objective】 To explore the impact of intrapartum antibiotic prophylaxis (IAP) on antibiotic resistance genes (ARGs) in the gut microbiota of infants up to 6 months of age and their longitudinal changes, in order to provide theoretical basis for the rational use of antibiotics and antibiotic resistance control. 【Methods】 Fecal samples were collected within 3 days, 2 months, and 6 months from a maternal and birth cohort conducted between January 2018 and June 2019. A panel of 6 common ARGs (aac(6′)-Ib, qnrS, blaTEM, ermB, mecA, tetM) were tested, the absolute abundance and positive detection rate by qPCR were calculated. Nonparametric and linear mixed model (LMM) analysis were used to assess the influence of IAP on the absolute abundance of antibiotic resistance genes and the longitudinal changes in their abundance at the three time points. 【Results】 A total of 157 samples from 65 singleton infants were analyzed, including 15 mothers (23.1%) who received IAP. The detection rate of ARGs was high in infants up to six months of age, and the abundance of ARGs tended to increase over time. IAP significantly increased the abundance of the mecA gene in the gut microbiota of vaginally delivered infants at 6 months of age (6.1±1.1 in the VDIAP group vs. 3.8±4.6 in the VDno-IAP group, P=0.046). Additionally, in cesarean section infants, there was a significant increase in the abundance of aac(6′)-Ib genes at 2 months (β=3.81, ,P<0.05), P<0.05] and 6 months of age (β=4.89, ,P<0.001), P<0.001) compared to 3 days of age. 【Conclusions】 The findings suggest that IAP can increase the abundance of ARGs in 6-month-old infants, and this effect is still significant after stratifying by delivery mode. Therefore, the rational and standardized use of intrapartum antibiotics may help reduce the development of antibiotic resistance.
