Objective To observe the effects of electro-acupuncture on Jiaji acupoints combine with treadmill training on tibia bone mass of rabbits with sciatic nerve injury,so as to provide the theoretical support for better project to maintain normal metabolism of bone after peripheral nerve injury.Methods A total of 24 New Zealand rabbits were randomly divided into four groups (n =6),namely a model group,a sham group,a treadmill group and an electro-acupuncture + treadmill group according to a random number table.The sciatic nerve of rabbits in the model,treadmill and electro-acupuncture + treadmill group was clamped using hemostatic forceps to establish the model of sciatic nerve injury,while that of the sham group was not clamped,just cut soft tissue around the sciatic nerve.Three days after modeling,the rabbits in treadmill group and the electro-acupuncture + treadmill group were given treadmill training and electro-acupuncture combine with treadmill training respectively,lasting 4 months,whereas those in the sham and the model groups were not given any intervention.Right after modeling,the behavior of rabbits in four groups was observed.Four weeks after treatment or feeding,their bone mineral density and bone strength of tibia were measured.Results Four weeks after treatment,there was significant reduction in bone density and bone strength of tibia in the model,the treadmill and the electro-acupuncture + treadmill groups compared with those in the sham group(P ＜ 0.05) ; the bone mineral density and bone strength of tibia in the electro-acupuncture + treadmill group were 0.17 ± 0.01 g/cm2 and 161.92 ± 43.27 N respectively,significantly higher than those in both the model and the treadmill groups (P ＜ 0.05).Conclusion Electro-acupuncture combined with treadmill training can improve tibia bone mineral density and bone strength after sciatic nerve injury and facilitate the normal metabolism of the bone and to maintain its normal function.

OBJECTIVETo explore the changes in HBsAg titer and HBV DNA load and their correlation in patients with chronic hepatitis B (CHB) and HBV-related liver cirrhosis (HBV-LC).

METHODSForty-six patients with mild to moderate CHB (CHB-LM), 24 patients with severe CHB (CHB-S), and 28 patients with HBV-LC at admission, and 51 patients with HBV-LC at 4.08 ± 3.06 months during antiviral treatment were tested for serum HBsAg titer and HBV DNA load using Abbott chemiluminescence and fluorescence quantitative PCR, respectively.

RESULTSThe serum HBsAg titer and HBV DNA load gradually decreased with increased disease severity (from CHB-LM, CHB-S to HBV-LC; χ(2)=12.537 and 8.381, respectively, P<0.05). HBsAg titer and HBV DNA load were significantly higher in CHB-LM and CHB-S groups than in HBV-LC group (P<0.05), but comparable between CHB-LM and CHB-S groups (Z=-0.649 and 0.032, respectively, P>0.05). Among HBeAg-positive patients, HBsAg titer and HBV DNA load tended to decrease with increased disease severity (from CHB-LM, CHB-S to HBV-LC; χ(2)=6.146, P=0.046 and χ(2)=1.017, P>0.05; respectively), and CHB-LM group had significantly higher HBsAg titer than HBV-LC group (Z=-2.247, P=0.025). Among the HBeAg-negative patients, serum HBsAg and HBV DNA load gradually declined with the disease severity (χ(2)=8.660 and 13.581, respectively, P<0.05), and were obviously higher in CHB-LM and CHB-S groups than in HBV-LC group (P<0.05). Positive correlations were found between serum HBsAg and HBV DNA levels in CHB-LM (r=0.389, P=0.009) and HBV-LC groups (r=0.431, P=0.022), but not in CHB-S group (r=0.348, P=0.104). After antiviral therapy, the serum HBsAg titer was slightly decreased (Z=-1.050, P=0.294) while HBV DNA load markedly reduced (Z=-5.415, P<0.001), showing no correlation between them (r=0.241, P=0.111) or between the measurements before and after treatment (r=0.257, P=0.085).

CONCLUSIONSerum HBsAg titer and HBV DNA load decreases progressively from CHB-LM to CHB-S and HBV-LC in both HBeAg- positive and -negative patients. The serum HBsAg titer is positively correlated with HBV DNA load, but their levels are not consistently parallel.

Objective:A genome-wide molecular characterization of FJ21351116, a strain of G3P[8]-E2 2021 collected in Fujian, China, was performed.Methods:Whole genome sequencing of FJ21351116 was performed using a high-sensitivity group A rotavirus whole genome sequencing method. Genomic characteriza-tion of the virus was assessed by nucleic acid sequence analysis using MEGA 11.0, Geneious 9.0.2 and DNASTAR software. Neutralization epitopes of VP7 and VP4 (VP8*) were analyzed using BioEdit v. 7.0.9.0 and PyMOL v. 2.5.2.Results:In this study, FJ21351116 was shown to be a G3-P[8]-I2-R2-C2-M2-A2-N2-T2-E2-H2 genotype, and the result of phylogenetic tree showed that the VP7, VP4, VP3, and NSP2-NSP5 genes of the FJ21351116 strain were related to the equine-like DS-1-like G3P[8] genes that have been detected in Japan in recent years. VP6, VP1, VP2, and NSP1 genes are closely related to G2P[4] in most countries, especially in Singapore, suggesting that this strain was formed by genetic reassortment during the evolution of equine-like G3P[8] and G2P[4]. Evolutionary relationships between the VP7/VP4 genes of FJ21351116 and Rotarix and RotaTeq vaccines suggest that the multiple mutations in both VP7 and VP4 (VP8*) neutralizing antigenic epitopes and vaccine amino acid sites. It is hypothesized that the Rotarix and RotaTeq vaccines may be less effective against equine DS-1-like G3P[8] RVA, and the sequence differences with Rotarix are higher than those with RotaTeq.Conclusions:In this study, we found a rare case of DS-1-like G3P [8] RVA strain in China. Currently, horse-like DS-1-like G3P [8] RVA is relatively rare in China and may be poorly protected by vaccine strains, emphasizing the importance of continuous monitoring of RVA strains and the development of efficient and full-coverage RVA vaccines.

Objective To systematically search,evaluate and summarize the best evidence for prevention and management of extravasation in peripheral intravenous infusion in NICU neonates,and provide a reference for clinical practice and standard formulation.Methods A comprehensive systematic search of websites and databases was conducted to explore literature on prevention and management of extravasation in NICU neonates,including clinical decisions,guidelines,expert consensuses,evidence summaries and systematic reviews.The search encompassed the entire period from database inception to July 2023.2 researchers independently evaluated the quality of the literature,extracted and integrated the evidence.Results The study included a total of 9 articles,comprising 1 clinical decision,3 guidelines,3 expert consensus documents,and 2 evidence summaries.Ultimately,25 pieces of evidence were synthesized,covering risk factors,catheter indwelling and maintenance,extravasation assessment and treatment,and team building,education and training.Conclusion The evidence provided practical and specific recommendations that can guide healthcare institutions in formulating strategies to prevent and treat extravasation during peripheral intravenous infusion in NICU neonates,while also offering evidence-based guidance for applying the evidence in clinical practice.

Objective To investigate and characterize the serum metabolite profile of patients with rheumatoid arthritis (RA),a common autoimmune disease,which will be of help for early diagnosis in clinic.Methods Serum specimens from 26 patients with RA and 19 age-matched healthy volunteers were collected from the First Affiliated Hospital of Hunan University of Chinese Medicine from January through April 2015.Samples were detected on the gas chromatography-mass spectrometry (GC-MS),and serum metabolites were identified by the chemometric methods.Discriminative model of RA and healthy volunteers was established using partial least squares-linear discriminant analysis (PLS-LDA),and furthermore the established model was evaluated with double cross validation (DCV) for predicting ability.Finally,differential metabolites with clinical diagnostic potential were screened out by using subwindow permutation analysis (SPA).Results The established PLS-LDA discriminative model identified 48 metabolites.The total accuracy of the model approached 97.73％,in which the accuracy of the model for predicting RA and healthy volunteers was 96.15％ and 100％,respectively.Our studies screened out 3-hydroxy butyric acid,phosphoric acid,isoleucine,mannose and hexadecanoic acid with clinical diagnostic potential based on the SPA.Conclusions Metabolomics with the application of GC-MS combined with the PLS-LDA method can distinguish patients with RA and healthy volunteers,and can aid in potential early diagnosis of RA.

Objective To examine the changing antimicrobial resistance profile of Enterobacter spp.isolates in 53 hospitals across China from 2015 t0 2021.Methods The clinical isolates of Enterobacter spp.were collected from 53 hospitals across China during 2015-2021 and tested for antimicrobial susceptibility using Kirby-Bauer method or automated testing systems according to the CHINET unified protocol.The results were interpreted according to the breakpoints issued by the Clinical & Laboratory Standards Institute(CLSI)in 2021(M100 31st edition)and analyzed with WHONET 5.6 software.Results A total of 37 966 Enterobacter strains were isolated from 2015 to 2021.The proportion of Enterobacter isolates among all clinical isolates showed a fluctuating trend over the 7-year period,overall 2.5％in all clinical isolates amd 5.7％in Enterobacterale strains.The most frequently isolated Enterobacter species was Enterobacter cloacae,accounting for 93.7％(35 571/37 966).The strains were mainly isolated from respiratory specimens(44.4±4.6)％,followed by secretions/pus(16.4±2.3)％and urine(16.0±0.9)％.The strains from respiratory samples decreased slightly,while those from sterile body fluids increased over the 7-year period.The Enterobacter strains were mainly isolated from inpatients(92.9％),and only(7.1±0.8)％of the strains were isolated from outpatients and emergency patients.The patients in surgical wards contributed the highest number of isolates(24.4±2.9)％compared to the inpatients in any other departement.Overall,≤ 7.9％of the E.cloacae strains were resistant to amikacin,tigecycline,polymyxin B,imipenem or meropenem,while ≤5.6％of the Enterobacter asburiae strains were resistant to these antimicrobial agents.E.asburiae showed higher resistance rate to polymyxin B than E.cloacae(19.7％vs 3.9％).Overall,≤8.1％of the Enterobacter gergoviae strains were resistant to tigecycline,amikacin,meropenem,or imipenem,while 10.5％of these strains were resistant to polycolistin B.The overall prevalence of carbapenem-resistant Enterobacter was 10.0％over the 7-year period,but showing an upward trend.The resistance profiles of Enterobacter isolates varied with the department from which they were isolated and whether the patient is an adult or a child.The prevalence of carbapenem-resistant E.cloacae was the highest in the E.cloacae isolates from ICU patients.Conclusions The results of the CHINET Antimicrobial Resistance Surveillance Program indicate that the proportion of Enterobacter strains in all clinical isolates fluctuates slightly over the 7-year period from 2015 to 2021.The Enterobacter strains showed increasing resistance to multiple antimicrobial drugs,especially carbapenems over the 7-year period.

Objective To understand the changing distribution and antimicrobial resistance profiles of Proteus,Morganella and Providencia in hospitals across China from January 1,2015 to December 31,2021 in the CHINET Antimicrobial Resistance Surveillance Program.Methods Antimicrobial susceptibility testing was carried out following the unified CHINET protocol.The results were interpreted in accordance with the breakpoints in the 2021 Clinical & Laboratory Standards Institute(CLSI)M100(31 st Edition).Results A total of 32 433 Enterobacterales strains were isolated during the 7-year period,including 24 160 strains of Proteus,6 704 strains of Morganella,and 1 569 strains of Providencia.The overall number of these Enterobacterales isolates increased significantly over the 7-year period.The top 3 specimen source of these strains were urine,lower respiratory tract specimens,and wound secretions.Proteus,Morganella,and Providencia isolates showed lower resistance rates to amikacin,meropenem,cefoxitin,cefepime,cefoperazone-sulbactam,and piperacillin-tazobactam.For most of the antibiotics tested,less than 10％of the Proteus and Morganella strains were resistant,while less than 20％of the Providencia strains were resistant.The prevalence of carbapenem-resistant Enterobacterales(CRE)was 1.4％in Proteus isolates,1.9％in Morganella isolates,and 15.6％in Providencia isolates.Conclusions The overall number of clinical isolates of Proteus,Morganella and Providencia increased significantly in the 7-year period from 2015 to 2021.The prevalence of CRE strains also increased.More attention should be paid to antimicrobial resistance surveillance and rational antibiotic use so as to prevent the emergence and increase of antimicrobial resistance.
