Objective To investigate the changing distribution and antibiotic resistance (AMR) profiles of Staphylococcus spp.and Enterococcus spp.isolated from children in China.Methods A retrospective analysis was conducted on the Staphylococcus spp.and Enterococcus spp.isolated from children under 18 years in 52 hospitals participating in the CHINET program from January 2015 to December 2021.The results of antimicrobial susceptibility test (AST) were interpreted according to the Clinical and Laboratory Standards Institute (CLSI) breakpoints (2021 edition).Results In the 7-year period,46334 strains of Staphylococcus were isolated from children,including 32537 strains of S.aureus and 13797 strains of coagulase-negative Staphylococcus.Meanwhile,16287 strains of Enterococcus were isolated,including E.faecium (8434 strains) and E.faecalis (6525 strains).S.aureus strains were mainly isolated from lower respiratory tract specimens (43.4％±6.7％),wound secretions (27.8％±4.3％) and blood (6.2％±1.2％).Most of the E.faecalis strains (58.6％±5.1％) and E.faecium strains (62.9％±2.0％) were isolated from urine.Both Staphylococcus and Enterococcus strains were most frequently isolated from internal medicine wards.The prevalence of methicillin-resistant S.aureus (MRSA) and coagulase-negative Staphylococcus (MRCNS) was 29.5％ and 79.8％,respectively.The prevalence of MRSA was relatively high in neonates (0-28 days) and infants (>28 days to 1 year old),31.7％ and 30.9％,respectively.MRSA strains showed low and decreasing resistance rate to gentamicin,rifampicin,levofloxacin,and trimethoprim-sulfamethoxazole from 2015 to 2021.None of vancomycin-resistant or linezolid-resistant Staphylococcus was detected.Vancomycin-resistant or linezolid-resistant Enterococcus strains were rarely detected (0 to 1.0％).Moreover,more than 1.0％ of the E.faecalis isolates were resistant to linezolid in recent two years.Conclusions From 2015 to 2021,S.aureus,E.faecalis,and E.faecalis were still the most common gram-positive bacteria isolated from children.The prevalence of MRSA did not change significantly from 2015 to 2022.MRSA strains showed a trend of decreasing antimicrobial resistance.The antimicrobial resistance rates of E.faecalis and E.faecalis did not change significantly during the 7-year period.Ongoing AMR surveillance in the Staphylococcus and Enterococcus isolates from children is important for prevention,control,and treatment of the infections caused by Staphylococcus and Enterococcus in pediatric patients.

AIM: To investigate the diagnostic value of the axial length/corneal radius of curvature(AL/CR)for myopia in children and adolescents.METHODS: PubMed, Embase, The Cochrane Library, CNKI, CBM, WanFang Data and VIP databases were searched to collect clinical research on the value of AL/CR in diagnosing myopia in children and adolescents, and the retrieval time was from establishment to September 30, 2023. The QUADAS-2 tool was used to evaluate the quality of the extracted literature. A random-effects model was used to pool diagnostic test data, Meta-regression and subgroup analysis were performed to explore sources of heterogeneity.RESULTS: A total of 10 articles involving 19 872 study participants were included, and Meta-analysis showed that the pooled sensitivity of the AL/CR for the diagnosis of myopia in children and adolescents was 0.91[95%CI(0.90-0.91)], the pooled specificity was 0.84 [95%CI(0.84-0.85)], and area under the SROC curve of 0.95 [95%CI(0.93-0.96)].CONCLUSION: The AL/CR is a good indicator of myopia in children and adolescents.

Objective:To investigate the clinical characteristics of pediatric methicillin-resistant Staphylococcus aureus (MRSA) infection and the antibiotic sensitivity of the isolates. Methods:The clinical data of children with MRSA infection and antibiotic sensitivity of the isolates from 11 children′s hospitals in Infectious Diseases Surveillance of Paediatrics (ISPED) group of China between January 1, 2018 and December 31, 2018 were collected retrospectively. The children′s general condition, high-risk factors, antimicrobial therapy and prognosis, differences in clinical disease and laboratory test results between different age groups, and differences of antibiotic sensitivity between community-acquired (CA)-MRSA and hospital-acquired (HA)-MRSA were analyzed. The t test and Wilcoxon rank sum test were used for statistical analysis of the quantitative data and Chi-square test were used for comparison of rates. Results:Among the 452 patients, 264 were males and 188 were females, aged from 2 days to 17 years. There were 233 cases (51.5%) in the ≤1 year old group, 79 cases (17.5%) in the>1-3 years old group, 29 cases (6.4%) in the >3-5 years old group, 65 cases (14.4%) in the >5-10 years old group, and 46 cases (10.2%) in the>10 years old group. The main distributions of onset seasons were 55 cases (12.2%) in December, 47 cases (10.4%) in February, 46 cases (10.2%) in November, 45 cases (10.0%) in January, 40 cases (8.8%) in March. There were 335 cases (74.1%) CA-MRSA and 117 (25.9%) cases HA-MRSA. Among all cases, 174 cases (38.5%) had basic diseases or long-term use of hormone and immunosuppressive drugs. During the period of hospitalization, 209 cases (46.2%) received medical interventions. There were 182 patients (40.3%) had used antibiotics (β-lactams, glycopeptides, macrolides, carbapenems, oxazolones, sulfonamides etc) 3 months before admission. The most common clinical disease was pneumonia (203 cases), followed by skin soft-tissue infection (133 cases), sepsis (92 cases), deep tissue abscess (42 cases), osteomyelitis (40 cases), and septic arthritis (26 cases), suppurative meningitis (10 cases). The proportion of pneumonia in the ≤1 year old group was higher than the >1-3 years old group,>3-5 years old group,>5-10 years old group,>10 years old group (57.5% (134/233) vs. 30.4% (24/79), 31.0% (9/29), 38.5% (25/65), 23.9% (11/46), χ 2=17.374, 7.293, 7.410, 17.373, all P<0.01) The proportion of skin and soft tissue infections caused by CA-MRSA infection was higher than HA-MRSA (33.4% (112/335) vs. 17.9% (21/117), χ 2=10.010, P=0.002), and the proportion of pneumonia caused by HA-MRSA infection was higher than CA-MRSA (53.0% (62/117) vs. 42.1% (141/335), χ 2=4.166, P=0.041). The first white blood cell count of the ≤1 year old group was higher than that children > 1 year old ((15±8)×10 9/L vs. (13±7)×10 9/L, t=2.697, P=0.007), while the C-reactive protein of the ≤1 year old group was lower than the 1-3 years old group,>5-10 years old group,>10 years old group (8.00 (0.04-194.00) vs.17.00 (0.50-316.00), 15.20 (0.23-312.00), 21.79(0.13-219.00) mg/L, Z=3.207, 2.044, 2.513, all P<0.05), there were no significant differences in procalcitonin (PCT) between different age groups (all P>0.05). After the treatment, 131 cases were cured, 278 cases were improved, 21 cases were not cured, 12 cases died, and 10 cases were abandoned. The 452 MRSA isolates were all sensitive to vancomycin (100.0%), linezolid (100.0%), 100.0% resistant to penicillin, highly resistant to erythromycin (85.0%, 375/441), clindamycin (67.7%, 294/434), less resistant to sulfonamides (5.9%, 23/391), levofloxacin (4.5%, 19/423), gentamicin (3.2%, 14/438), rifampicin (1.8%, 8/440), minocycline (1.1%, 1/91). The antimicrobial resistance rates were not significantly different between the CA-MRSA and HA-MRSA groups (all P>0.05). Conclusions:The infection of MRSA is mainly found in infants under 3 years old. The prevalent seasons are winter and spring, and MRSA is mainly acquired in the community. The main clinical diseases are pneumonia, skin soft-tissue infection and sepsis. No MRSA isolate is resistant to vancomycin, linezolid. MRSA isolates are generally sensitive to sulfonamides, levofloxacin, gentamicin, rifampicin, minocycline, and were highly resistant to erythromycin and clindamycin. To achieve better prognosis. clinicians should initiate anti-infective treatment for children with MRSA infection according to the clinical characteristics of patients and drug sensitivity of the isolates timely and effectively.

Super hydrophobic interface modified with silver nanoparticles was fabricated for the detection of pesticide residues.By using a chemical reduction method,silver nanoparticles were deposited on the substrate surfaces with different microscopic pore structures.Two kinds of composite substrates,including regular stainless steel mesh and cellulose polyester film,were used.The pre-treatment of the substrate with fluoridated reagents was used to form a super hydrophobic interface,which made the target molecules on the surface concentrate effectively.The surface with the cellulose polyester substrate was used to detect Rhodamine 6G (R 6G) effectively with surface enhanced Raman scattering (SERS) technique.The results showed that the detection hmit was 10-16 mol/L.In addition,the surfaces based on the stainless steel mesh and cellulose polyester substrate were used to detect trichlorfon pesticide with detection limits of 1 × 10-15 mol/L and 1 × 10-16 mol/L,respectively.

The leading cause of drug withdrawal from market and clinical trials failure is drug-induced liver injury (DILI). Varying clinical, histological and laboratory features of DILI, as well as undefined underlying mechanisms, hinder patients to be diagnosed in the early-stage of the disease and receive effective treatments. Conventional indicators, like serum transaminases and bilirubin, have inevitable limitations referring to sensitive prediction and specific detection of DILI. In order to reduce the occurrence of DILI, researchers have attempted to discover potential biomarkers with higher specificity and sensitivity from blood and urine in recent years. This article aims to review recent advances in biomarkers of DILI.

Objective To discuss the surgical indications,relative merits and clinical outcomes of anterior reconstruction plate fixation for treating unstable posterior pelvic ring injuries.MethodsA retrospective study was done on clinical data of 36 patients with unstable posterior pelvic ring injuries treated with anterior reconstruction plate fixation from August 2004 to July 2010 and followed up for minimum one year.There were 25 males and 11 females,at mean age of 35.8 years ( range,13-62 years).There were two patients with anterior dislocation of the sacroiliac joint and 34 with posterior dislocation.According to Tile classification,there were four patients with type B fractures ( B1:3,B2:1 ) and 32 with type C fractures (C1-1:17,C1-2:12,C2:2,C3:1 ).Results All patients were followed up for average 2.3 years ( range,1-6 years).Fat liquefaction and superficial infection were founded in two patients who were cured by dressing change and frequent but low-dose blood transfusion.Eight patients were subjected to iatrogenic lateral femoral cutaneous nerve injury.Meanwhile,five of them was recovered after treatment with neurotrophic drugs,but there were still three patients leaving lateral thigh numbness.One patient had L5 nerve root injury due to pull force,and was recovered after three months of neurotrophic drug therapy.According to Matta and Tometta criteria,the reduction results were excellent in 23 patients,good in 11 and fair in four,with excellence rate of 94％.No reduction loss or implant failure occurred.According to Majeed scoring system,the clinical outcomes were excellent in 17 patients,good in 14,fair in four and poor in one,with excellence rate of 86％.Of the seven patients pre-operatively associated with sacral plexusinjury,three obtained full recovery,two got partial recovery and two were free from recovery.Conclusion The anterior reconstruction plate fixation takes advantages of wide surgical indications,simple exposure,low infection rate,satisfactory reduction and solid fixation and may be a main treatment method for unstable posterior pelvic ring injuries.
