Objective:To compare the efficacy of ustekinumab (UST) and vedolizumab (VDZ) in achieving transmural healing in active Crohn′s disease (CD).Methods:From March 1, 2020 to November 30, 2024, 112 patients with active CD treated with UST or VDZ at the Department of Gastroenterology, Tenth People′s Hospital of Tongji University were retrospectively enrolled. According to the medication regimen, the 112 patients were divided into UST group (61 cases) and VDZ group (51 cases). Collected the data at baseline, such as the disease phenotype, other medication history, and clinical indicators including C-creative protein (CRP), etc. Clinical disease activity and endoscopic disease activity were assessed by Harvey-Bradshaw index (HBI) and simplified endoscopic score for Crohn′s disease (SES-CD), respectively. Transmural healing was evaluated according to the intestinal wall thickness measured by intestinal imaging examination of the affected intestinal segment. Transmural healing was defined as bowel wall thickness <0.3 cm and 110 obvious signs of inflammation, clinical remission was defined as HBI≤4, and endoscopic remission was defined as a reduction in SES-CD ≥50% or a score of ≤2. The primary endpoint was transmural healing rate within one year after treatment. The secondary endpoints were endoscopic healing rate and clinical remission rate at 13 to 24th week and 30 to 52nd week after treatment. Chi-square test or Fisher′s exact test was used to compare the efficacy of the 2 medications.Results:There was no significant difference in transmural healing rate between UST group and VDZ group within 1 year after treatment (16.4% (10/61) vs. 23.5% (12/51), χ2=0.90, P=0.344). There were no significant differences in the healing rate between UST group and VDZ group in patients with specific baseline characteristics before treatment, including CD with stenosis, with perianal disease, no history of glucocorticoid use, secondary loss of response to anti-tumor necrosis factor (TNF)-α, SES-CD 7 to 15, decreased body mass index, and increased CRP (18.2%(6/33) vs. 19.4%(7/36), 17.9%(7/39) vs. 19.4%(6/31), 17.1%(6/35) vs. 24.2%(8/33), 20.0%(8/40) vs. 3/18, 14.3%(5/35) vs. 19.2%(5/26), 15.0%(3/20) vs. 3/10, 21.4%(6/28) vs. 5/16), all P>0.05). There was no significant difference in the clinical remission rate or endoscopic remission rate between the UST group and the VDZ group from 13 to 24th week (7/14 vs. 9/18, 3/14 vs. 7/18, RR=1.000 and 0.551, 95% confidence interval: 0.497to 2.011, 0.173to 1.755, χ2=<0.01, Fisher′s exact test, both P>0.05). There was no significant difference in clinical remission rate or endoscopic remission rate between UST group and VDZ group from week 30 to week 52 after treatment (68.5% (37/54) vs. 74.4% (32/43), 27.8% (15/54) vs. 32.6% (14/43), RR=0.921 and 0.853, 95% confidence interval: 0.716 to 1.184, 0.464 to 1.568, χ2=0.41 and 0.26, both P>0.05). In UST group, the proportion of patients with normal hemoglobin after transmural healing was higher than that of patients without transmural healing (9/10 vs. 45.1% (23/51), and the difference was statistically significant ( χ2=5.08, P=0.024). However, there were no significant differences in the proportion of patients with normal body mass index, CRP, platelet count, prealbumin, albumin, interleukin-6 or TNF-α levels after treatment between those who achieved transmural healing and those who did not in either UST group or VDZ group (all P>0.05). And in VDZ group there was no significant difference in the proportion of patients with normal hemoglobin between those who achieved transmural healing and who did not (all P>0.05). Conclusion:UST and VDZ exhibit similar efficacy in transmural healing within one year of treatment in patients with active CD.

Objective:To study the effects of hypoxia on the autophagy level in the spleen of mice with OSAHS.Methods:Mouse OSAHS hypoxia model was established in 24 C57BL/6 mice and the mice were divided into 3 groups:normoxic group,hypoxic group and resveratrol group(n=8).Real time PCR,Western blot and immunohistochemical staining(IHC)were used to detect the mRNA and protein expression of autophagy related proteins microtube associated protein 1 light chain 3 B(LC3B),myosin-like BCL2 inteacting protein(Beclin1)and autophagy related gene 5(ATG5)in mouse spleen respectively.Results:The mRNA expres-sion of LC3B,Beclin1,and ATG5 in the hypoxic group was lower than that in the normoxic group(P＜0.01,P＜0.01,P＜0.001),resveratrol upregulated the expression levels of LC3B and ATG5 mRNA in the hypoxic group(P＜0.05,P＜0.001),but did not up-regulate the expression of Beclin1(P＞0.05).The protein expression levels of LC3B,Beclin1 and ATG5 in the hypoxic group were lower than that in the normoxic group(P＜0.05,P＜0.05,P＜0.01).Resveratrol upregulated the expression levels of LC3B and ATG5 in the hypoxic group(P＜0.05,P＜0.01),but did not upregulated the expression of Beclin1(P＞0.05).IHC test showed that the expression level of LC3B,Beclin1 and ATG5 in the hypoxic group was lower than that in the normoxic group(P＜0.01,P＜0.01,P＜0.001).Resveratrol increased the expression level of LC3B and ATG5 in the hypoxic group(P＜0.05,P＜0.01),but did not upregulate the expression of Beclin1(P＞0.05).Conclusion:Hypoxia may inhibite the autophagy level of spleen in mice.Resvera-trol derivatives increases the autophagy level of mice under hypoxia condition,but has no significant effect on Beclin1 expression.

BACKGROUND:Peripheral nerve injuries can cause severe functional disabilities in patients,and long-segment nerve defects often fail to regenerate spontaneously.In recent years,tissue engineering techniques have gradually been applied to the repair of long-segment nerve injuries,yet research hotspots and development trends are unclear.OBJECTIVE:To analyze the research hotspots and trends in the field of peripheral nerve tissue engineering over the past 20 years using bibliometric software.METHODS:CiteSpace 6.2R6 software was employed to conduct highly cited analysis and keyword analysis on peripheral nerve tissue engineering literature published from 2004 to 2024 in the Web of Science and China National Knowledge Infrastructure(CNKI)databases.The keyword analysis encompasses keyword co-occurrence analysis,keyword clustering analysis,keyword timeline analysis,and keyword emergence analysis.RESULTS AND CONCLUSION:A total of 2 961 articles from the Web of Science database and 1171 articles from the CNKI database were included.The number of publications in the Web of Science database showed fluctuations but exhibited an overall increasing trend year by year,while the publication volume in the CNKI database remained relatively stable annually.Most of the top ten most cited articles in the Web of Science database were review articles.The results of the keyword analysis from Web of Science and CNKI databases indicated that the most studied nerve tissue engineering materials over the past 20 years include silk fibroin,collagen,chitosan,polycaprolactone,polylactic acid,and graphene.The biochemical cues investigated in these materials include olfactory ensheathing cells,Schwann cells,stem cells,and nerve growth factors.The most commonly employed external physical factor is electrical stimulation applied to the materials.Among various tissue engineering techniques,electrospinning technology and 3D printing technology have been the most extensively researched.

The incidence of falls is high among the elderly population,particularly in patients with dementia.It was associated with their quality of life,accelerated disease progression,and reducing life expectancy.However,there is still a lack of relevant guidelines and recommendations for the occurrence,prediction,and intervention of falls in people with dementia.By reviewing the epidemiology,pathogenesis,risk factors,prediction models,and intervention measures related to falls in patients with dementia to provide a reference for clinicians to manage the whole process management of senile dementia patients.It was shown a higher risk of falling in elderly with dementia,which may be associated with visuospatial impairment,executive dysfunction,motor dysfunction,poor nutritional status,and a decline in daily living ability.Falling directly affects the prognosis of patients and increases the social and medical burden,which needs to be paid attention to.

BACKGROUND:Cervical disc degeneration is a common degenerative disease,and inflammatory proteins play an important role in cervical disc degeneration,but the specific mechanisms involved remain to be thoroughly investigated.OBJECTIVE:Using the Mendelian randomization method to assess the potential causal relationship between 91 inflammatory proteins and cervical disc degeneration.METHODS:Genome-wide association analysis statistics for 91 inflammatory proteins(from GCST90274758 to GCST90274848)were obtained from the Genome-Wide Association Analysis Catalog of publicly available genome-wide association analysis data and genome-wide association analysis data for cervical disc degeneration from the Finngen database(finngen_R10_M13_CERVICDISCV).Inverse variance weighting,MR-Egger regression,weighted median,weighted modeling,and simple modeling were used to investigate the causal relationship between inflammatory proteins and cervical disc degeneration.Sensitivity analyses were performed to test whether the results of the Mendelian randomization analysis were reliable,and then the inverse Mendelian randomization analysis was performed in the same way.RESULTS AND CONCLUSION:The results of the forward analysis showed that a total of six inflammatory proteins were significantly and causally associated with cervical disc degeneration,of which glial cell lineage-derived neurotrophic factor(odds ratio(OR)=1.095,95%confidence interval(CI):1.012-1.184,P=0.023),interleukin 4(OR=1.094,95%CI:1.002-1.194,P=0.045)and monocyte chemotactic protein-1 levels(OR=1.062,95%CI:1.001-1.127,P=0.048)showed a direct positive causal association with the risk of cervical disc degeneration;interleukin 17C(OR=0.906,95%CI:0.839-0.979,P=0.013),interleukin 18(OR=0.924,95%CI:0.866-0.986,P=0.017)and interleukin 2 levels(OR=0.894,95%CI:0.821-0.973,P=0.010)showed a direct negative causal association with the risk of cervical disc degeneration.The results of the inverse analysis showed that when cervical disc degeneration was used as exposure data,there was no significant causal relationship with any of the 91 inflammatory proteins.The results of the sensitivity analysis showed that the Cochran's Q test for the two-way Mendelian randomization,the MR-Egger regression method,and the MR-PRESSO results had P values greater than 0.05,indicating that there was no significant heterogeneity or multiplicity in the analysis of the causal effect between inflammatory proteins and cervical disc degeneration.To conclude,there may be a relatively significant potential causal relationship between glial cell line-derived neurotrophic factor,interleukin 4,monocyte chemotactic protein-1,interleukin 17C levels,interleukin 18,and interleukin 2 levels and cervical disc degeneration,which provides valuable clues for research on the potential mechanisms of cervical disc degeneration as well as early prevention and drug treatment of cervical disc degeneration.

Objective:To analyze the drug-resistance pattern and molecular epidemiological characteristics of Enterobacteriales carrying the blaNDM gene in Lishui, aiming to guide clinical anti-infection treatment. Methods:Non-duplicate blaNDM-carrying Enterobacteriales, isolated from Lishui Central Hospital, were collected and identified by VITEK MS. The minimal inhibitory concentrations (MICs) were detected by the broth microdilution method. The ST types of the strains were determined by multilocus sequence typing (MLST). Plasmid types were identified by transformation or conjugation experiments and replication initiator amplification experiments. The transposon structures were detected by PCR amplification. Finally, the epidemic regularity of blaNDM gene in Lishui was analyzed from three levels: clonal group, plasmid, and mobile genetic elements. Results:A total of 109 blaNDM-positive strains were collected. Among them, 60 strains carried the blaNDM-1 gene and 49 strains carried the blaNDM-5 gene. The 109 strains showed 100% resistance to ceftazidime and cefotaxime. The resistance rates to peracillin-tazobactam and imipenem were higher than 80%. Strains carrying the blaNDM-5 gene were more resistant to meropenem than those carrying blaNDM-1 gene( P<0.05). A total of 68 STs were detected from 109 strains, and IncX3, IncFⅡγ, IncA/C and IncT/R plasmids were detected, and 90.83% of the blaNDM genes were located in the IncX3 plasmid. Twelve types of blaNDM gene surrounding structures existed, and they all carried the highly conserved blaNDM- bleMBL- trpF gene sequence. Conclusions:The blaNDM gene has diverse transmission modes in Lishui. The IncX3 plasmid is the main factor mediating its transfer, and all strains carry highly conserved blaNDM- bleMBL- trpF gene sequence.

BACKGROUND:Exercise as a form of active rehabilitation can improve the dysfunction caused by peripheral nerve injury,and different exercise modalities target different lesion sites and recovery mechanisms. OBJECTIVE:To comprehensively analyze the application and mechanisms of different exercise modalities in functional recovery from peripheral nerve injury. METHODS:A computerized search was conducted in PubMed and CNKI databases for relevant literature published before January 2024.The search terms used were"peripheral nerve injury,spinal cord,exercise,cerebral cortex,muscle atrophy,mirror therapy,blood flow restriction training"in both English and Chinese.Finally,77 articles were included for review. RESULTS AND CONCLUSION:Peripheral nerve injury can cause systemic pathological changes such as skeletal muscle atrophy,corresponding spinal cord segmental lesions,and sensorimotor cortex remodeling.Aerobic exercise can improve dysfunction by enhancing the immune response,promoting glial cell polarization,and promoting the release of nerve growth factor.Blood flow restriction exercise can regulate the secretion of muscle growth factor,promote muscle growth and enhance muscle strength.Mirror movement has a good effect in activating the cerebral cortex and reducing cortical remodeling.Different exercise modalities have potential benefits in functional recovery after peripheral nerve injury;however,there are still some problems and challenges,such as the choice of exercise modalities,the control of exercise intensity and frequency,and the detailed analysis of mechanisms.

Aromatic Chinese medicinal essential oils are volatile oils extracted from aromatic Chinese herbs， which can prevent and treat respiratory infectious diseases through multiple synergistic mechanisms including pathogen inhibition， immune regulation， and inflammatory response regulation. Essential oils are primarily used externally on the body to prevent infections and alleviate symptoms through methods like inhalation， smearing， topical application， bathing， gargling or as a suppository. They can also be utilized in the environment for disinfection and air purification， through methods like diffusion， vaporization， or spraying. The external application of essential oils extracted from Chinese aromatic herbs has the advantages of convenience， quick absorption， and simultaneous influence on both the body and mind. However， there are still challenges and deficiencies in aspects such as the positioning of functions， indications， safety， and the research on the mechanism of action. It has been proposed to combine the theory of aromatic Chinese medicinals with the characteristics of essential oils， and formulate prescriptions of Chinese medicinal essential oils under the principles of traditional Chinese medicine syndrome differentiation， and prevent and treat respiratory infectious diseases efficiently， accurately， and safely， thereby expanding the clinical application of aromatic Chinese medicinals and the preventive theory of traditional Chinese medicine.
