Objective To explore risk factors of sodium-dependent glucose transporters 2 （SGLT2） inhibitor-associated euglycemic diabetic ketoacidosis （euDKA） and to construct a risk prediction model. Methods A retrospective analysis was performed on the clinical data of type 2 diabetes patients treated with SGLT2 inhibitors in Dongnan Hospital of Xiamen University from January 2020 to December 2023, including age, gender and course of diabetes. The risk factors of SGLT2 inhibitor-associated euDKA were analyzed by univariate analysis and multivariate Logistic regression, and a prediction model was established. According to the receiver's operating characteristic （ROC） curve, the area under the curve （AUC） and the optimal critical value of the prediction model were determined. The prediction model was subjected to both internal and external validation. Results A total of 119 patients with type 2 diabetes treated with SGLT2 inhibitors were included in this study. Among them, there were 98 cases without euDKA （non-euDKA group）and 21 cases with euDKA （euDKA group）. Multivariate Logistic regression analysis showed the DKA history (OR=114.153), appetite or diet decreased three days before admission (OR=21.774), elevated neutrophil count (OR=2.056) and pre-hospital adjustment of hypoglycemic agents (OR=45.745) were independent factors to increase risks of euDKA associated with SGLT2 inhibitors （P<0.05）. Surgical history before admission was an independent factor to reduce this risk （OR=0.007, P<0.05）. By establishing the calculation formula of the prediction model = neutrophil count+6.571 （DKA history）−6.874 （surgical history before admission）+4.273 （appetite or diet decreased three days before admission）+5.302 （pre-hospital adjustment of hypoglycemic drugs）, the ROC curve was drawn. The AUC of the ROC of the prediction model was 0.982 （95%CI: 0.961-1.000, P<0.001）, with accuracy of 94.96%, sensitivity of 0.905, specificity of 0.959 and a critical value of 7.405. The AUC of ROC curve after the model’s ten-fold cross validation was 0.930. And the accuracy of the external validation of the prediction model was 85.29%. Conclusion The DKA history, appetite or diet decreased three days before admission, elevated neutrophil count and pre-hospital adjustment of hypoglycemic agents increased the risk of SGLT2 inhibitor-associated euDKA, while the surgical history before admission reduced this risk. The risk prediction model constructed on this basis could better predict the risk of SGLT2 inhibitor-associated euDKA.

Objective:To explore the diagnostic value and clinical application of metagenomic next-generation sequencing (mNGS) technology in pediatric urinary tract infections (UTI).Methods:In this retrospective study, the clinical data of children with UTI admitted to the Department of Nephrology, Children′s Hospital, Capital Institute of Pediatrics, from March 2023 to March 2024 were collected.The positive detection rates, timeliness, and consistency of mNGS technology were compared with those of urine culture.Measurement data were subject to test of normality.The independent sample t test, Chi-square test or Fisher′s exact probability test were used for comparison between groups. Results:A total of 193 patients were included.The positive detection rate of urine culture was 36.3% (70/193).Among 42 patients who underwent mNGS testing, 37 cases (88.1%) tested positive.The positive detection rate of mNGS was significantly higher than that of urine culture ( χ2=37.357, P<0.001).It took significantly less time to report mNGS results than to report urine culture results ( Z=3.524, P<0.001).In the 42 cases that underwent mNGS testing, 5 cases (11.9%) were negative for urine pathogens by both methods, and 21 cases (50.0%) were positive by mNGS but negative by urine culture.Among the remaining 16 cases (38.1%) positive by both mNGS and urine culture, 14 cases (33.3%) achieved fully matching results, 1 case (2.4%) was fully mismatched, and 1 case (2.4%) was partially matched.Comparison of the positive detection rate and the duration of anti-infective treatment prior to specimen collection between urine culture and mNGS showed that the median durations for urine culture and mNGS positivity were 5 and 20 days, and the difference was statistically significant ( χ2=0.537, P<0.001). Conclusions:mNGS technology has high sensitivity for diagnosing pathogens in pediatric UTI.Compared with urine culture, mNGS provides good consistency and significantly shortens the detection time.The positive detection rate is less affected by antimicrobial treatment.For children with UTI, especially those who have failed empirical anti-infective treatment and whose pathogen cannot be identified by urine culture, mNGS testing is recommended as early as possible.

Objective To explore the diagnostic value of endoscopic grading of gastric intestinal metaplasia (EGGIM) score under acetic acid-enhanced narrow band imaging (AA-NBI) observation mode for gastric intestinal metaplasia (GIM). Methods A total of 120 patients who underwent gastroscopy at Jinshan Hospital of Fudan University from February 2022 to February 2023 were selected. All patients underwent both white light and AA-NBI endoscopy, with photographic records of intestinal metaplasia in five areas: greater curvature of antrum, lesser curvature of antrum, greater curvature of corpus, lesser curvature of corpus and incisura. EGGIM score was performed: 0 for no intestinal metaplasia, 1 point for focal intestinal metaplasia (GIM area ratio≤30%), 2 points for extensive intestinal metaplasia (GIM area ratio＞30%), with a total score of 10 points. Targeted biopsies were performed on suspicious GIM lesions found during endoscopy. If no suspicious GIM lesions were observed, random biopsies were performed according to the updated Sydney system. The pathological histological examination results were staged based on the operative link on gastric intestinal metaplasia assessment (OLGIM) system. The diagnostic value of EGGIM score for OLGIM stage Ⅲ-Ⅳ patients was evaluated using receiver operating characteristic (ROC) curves. Results The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of AA-NBI in detecting GIM were 96.3%, 91.6%, 94.5%, 95.0%, and 93.6%, respectively. The area under the ROC curve for EGGIM diagnosing OLGIM stage Ⅲ-Ⅳ was 0.952 (95%CI 0.914-0.990). The optimal cut-off value for EGGIM was 5 points, with a sensitivity of 96.7% (95%CI 87.6%-99.4%) and specificity of 88.1% (95%CI 76.5%-94.7%). Conclusions EGGIM score (≥5 points) under AA-NBI mode has good diagnostic capability for patients with OLGIM stage Ⅲ-Ⅳ.

ObjectiveTo analyze the genomic characteristics of Streptococcus pyogenes (GAS) isolated from children with respiratory tract infections in a tertiary hospital in Jinshan District of Shanghai during 2013‒2024, to compare the changes in trend for genomic characteristics before and after 2000, and to provide scientific data for the prevention and control of GAS infections. MethodsGAS strains isolated from children with respiratory tract infections in this hospital were collected from 2013 to 2024. Antimicrobial susceptibility of the isolated strains to 12 antibiotics, including penicillin, cefotaxime, cefepime, linezolid, vancomycin, meropenem, chloramphenicol, ofloxacin, levofloxacin, erythromycin, clindamycin, and tetracycline, was determined using broth microdilution plate method. Besides, whole genome sequencing (WGS) was used to analyze multilocus sequence type (MLST), emm typing, carriage of superantigen genes, mobile genetic element (MGE), carriage of virulence gene, and genomic phylogenetic tree of the isolated strains. ResultsA total of 50 GAS strains were collected and identified from children with respiratory tract infections aged 4‒14 years old, and the resistance rates of those isolates to erythromycin, clindamycin, and tetracycline were 100.00%, 100.00%, and 86.00%, respectively. There were two emm types in the GAS isolates; the emm12 type accounted for 76.00% (38/50), corresponding to ST36 type, and the emm1 type accounted for 24.00% (12/50), corresponding to ST28, ST1274, and new-1 types. There was a statistically significant difference in the constitution of the MLST before and after 2020 (P=0.015). All the isolates carried the superantigen genes speC, speG, ssa, and smeZ. The predominant emm12 isolates belonged to the Clade Ⅱ, carrying the mobile elements ICE-emm12 (harboring erythromycin-resistance gene ermB and tetracycline-resistance gene tetM) and ΦHKU.vir (carrying virulence genes speC and ssa). The emm1 isolates carried the mobile elements ICE-HKU488 (harboring erythromycin-resistance gene ermB and tetracycline-resistance gene tetM) and ΦHKU488.vir (carrying virulence genes speC and ssa), and had close phylogenetical relationships with isolates from Hong Kong, China. No M1_UK new clone strains were found. The ST1274 isolates of emm1 were newly discovered in 2020‒2024, and belonged to a separate phylogenetic clade. ConclusionGAS strains isolated from children with respiratory tract infections in a tertiary hospital in Jinshan District of Shanghai exhibit a high resistance to erythromycin, clindamycin, and tetracycline. It is recommended that the clinical treatments change to use other antimicrobial drugs, such as penicillin, third-generation cephalosporins, and fluoroquinolones. During 2020‒2024, a new ST1274 clone strain is discovered in emm1 GAS isolates, without M1_UK new clone strains being found. It is essential to continuously concern locally prevalent GAS strains and perform early identification of MLST types to promptly monitor the internal changes of the bacterial population and potential prevalence of new clones.

Objective:To explore potential risk factors for central lymph node metastasis (CLNM) in papillary thyroid microcarcinoma (PTMC).Methods:The clinicopathological data of 304 PTMC patients admitted to Baotou Cancer Hospital from Oct 2021 to Mar 2023 were retrospectively analyzed. The risk factors of CLNM were analyzed using unifactorial and multifactorial regression.Results:The rate of central regional lymph node metastasis in 304 patients with PTMC was 46.7% (142/304). Univariate analysis showed that male, age <45 years, maximum cancerous lesion diameter ≥5 mm, total cancerous lesion diameter ≥9.5 mm, anterior-posterior lesion diameter ≥5 mm, anterior-posterior lesion diameter ratio of cancerous lesions ≥0.48, breaching of thyroid capsule, number of lymph nodes on the side of cancerous lesions ≥5, and antithyroid peroxidase antibody ≤34 IU/ml were associated with CLNM (all P<0.05); Logistic multivariate regression analysis showed that. male, age <45 years, total diameter of cancer foci ≥9.5 mm ( OR=2.052, 95% CI: 1.176-3.581, P=0.011), anteroposterior diameter ratio of cancer foci ≥0.48 ( OR=2.076, 95% CI: 1.161-3.711, P=0.014), number of lymph nodes on the side of cancer foci ≥5, and anti-thyroid peroxidase antibody ≤34 IU/ml were independent risk factors for CLNM. Conclusion:Male, age ,total diameter of cancer foci, anterior-posterior diameter ratio of cancer foci, number of lymph nodes on the side of cancer foci, and anti-thyroid peroxidase antibody level are all independent risk factors for CLNM in patients with PTMC.

With the widespread use of antimicrobial agents, bacterial drug resistance has become an increasingly severe issue, posing significant challenges to global healthcare. Traditional Chinese medicine (TCM) has emerged as a research focus in the field of bacterial resistance due to its broad sources, high safety profile, low toxicity, and antimicrobial mechanisms distinct from those of chemical drugs. Studies have shown that various TCM herbs, such as Scutellaria baicalensis, exert antibacterial effects through multiple pathways, including disrupting the integrity of bacterial cell walls and membranes, inhibiting nucleic acid and protein synthesis, and impairing energy production and metabolism. Additionally, certain TCM herbs, including Scutellaria baicalensis, Coptis chinensis, and Fritillaria thunbergii, can reverse antimicrobial resistance by eliminating resistant plasmids, inhibiting bacterial efflux pump function, and suppressing β-lactamase activity. TCM holds promising potential for antibacterial applications and synergistically reversing antimicrobial resistance, though systematic analyses remain limited. This review summarizes the mechanisms of antibacterial action of TCM and current research on its synergistic use with antimicrobial agents to reverse drug resistance, aiming to provide insights for developing novel TCM-based antimicrobials and addressing bacterial resistance.

Although small in size, the eyeballs are extremely important in function, and are delicate and complex in structure. With the wide application of acupuncture for eye diseases and the high frequency of use of intra-orbital points, the incidence of acupuncture accidents increases accordingly in treatment. We reported two recent accident cases, retinal tear and ciliochoroidal detachment that occurred during the regular operation of acupuncture and acupoint injection at intra-orbital points, in order to strengthen people's awareness of acupuncture accidents caused by acupuncture at the points in the orbital region, and enhance the sound development and comprehensive promotion of acupuncture in treatment of eye diseases.

Objective:To evaluate the efficacy and safety of rituximab (RTX) in children with steroid resistant nephrotic syndrome (SRNS).Methods:The was a retrospective observational study. A retrospective analysis was conducted on the clinical data of 14 children with SRNS who received RTX treatment in the Department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics from July 2021 to August 2023. The changes in urinary protein content, renal function, serum albumin, immunoglobulin and other indicators before and after RTX medication were compared to evaluate the clinical efficacy and safety of RTX treatment for SRNS.Results:A total of 14 children with SRNS were selected for this study, with a male to female ratio of 6:8. The age of onset of kidney disease was (4.36±3.12) years, and 8 of them underwent kidney biopsy. Among them, 6 cases showed focal segmental glomerulosclerosis in renal pathology, and 2 cases showed minimal change disease. The age of 14 children who first used RTX was (8.45±3.98) years old, with a dose of 375 mg/m 2 and a maximum dose of 500 mg. The number of children who had used 2, 3, 4, and 5 doses of RTX was 6, 6, 1, and 1, respectively. RTX was administered orally with compound sulfamethoxazole to prevent infection. Glucocorticoids and immunosuppressants were discontinued 4.0(2.5, 6.5) months after the first dose of RTX. The median follow-up time was 10.5(6.0, 18.3) months. By the end of the 3-month, 6-month, and follow-up endpoints, the complete remission rates of kidney disease in the children were 100.0%(14/14), 85.7%(12/14), and 64.3%(9/14), respectively. Five children experienced kidney disease recurrence. Compared with before the first dose of RTX treatment, the serum albumin and height significantly increased, while body mass index significantly decreased at the end of follow-up (all P<0.05). There was no statistically significant difference in urinary protein content, renal function, and IgG (all P>0.05). During the RTX treatment, all 14 children did not experience any infusion reaction, and there were no serious infections during follow-up. One case was diagnosed with hypogammaglobulinemia. Conclusions:RTX can improve the remission rate and recurrence rate of SRNS children, reduce the dosage of glucocorticoids and related drug untoward reaction, significantly improve patient height and BMI, with minimal side effects. Especially for SRNS patients who cannot be relieved by the combination of glucocorticoids and immunosuppressants, RTX may be considered.

Objective:To analyze the clinical characteristics of renal abscess in children and provide suggestions for early diagnosis and treatment.Methods:The clinical data including general information, laboratory data, imaging results, treatment and prognosis of 20 pediatric patients with renal abscess admitted to the Department of Nephrology, Capital Center for Children's Health Capital Medical University were analyzed retrospectively.Results:A total of 8 males and 12 females were enrolled. The age of onset was 3.0 (0.8, 9.0) years. All cases had fever. Six cases presented with abdominal pain, 6 cases had poor appetite, 5 cases had vomiting and 5 cases urinary tract irritation symptoms. Laboratory data showed elevated white blood cells 20.4 (17.4,26.3)×10 9/L, C-reactive protein 126 (77, 154)mg/L, erythrocyte sedimentation rate 60 (41,73) mm/1 h in 20 cases and procalcitonin 4.7 (1.2,33.5)μg/L in 10 cases. Totally 18 cases had pyuria. Urine culture was positive in 8 cases. Enterococcus faecium and Pseudomonas aeruginosa was detected in 2 cases. Klebsiella pneumoniae was found in 1 case after performing blood culture. Renal abscess was confirmed in all cases by doing contrast-enhanced CT scan, while only 9 cases with abscesses were identified by using renal ultrasound. There were 14 cases with renal abscess formation confirmed at onset by performing magnetic resonance imaging. Nine cases were accompanied with congenital anomalies of the kidney and urinary tract. All cases received conservative medical treatment. Intravenous broad-spectrum antibiotics were administered for 23 (14, 39) d initially, while the medication in 11 cases were upgraded to meropenem or imipenem. Oral antibiotics were continued for 23 (14, 28) d after discharge in all cases. Within 1 year of follow-up, except for 1 case of recurrence, the others had a favorable prognosis. Conclusions:Renal abscess should be suspected for children presenting with unexplained fever, vomiting, abdominal pain, elevated white blood cell count, C-reactive protein, erythrocyte sedimentation rate and pyuria. Ultrasonography is suitable for screening and follow-up, while CT or magnetic resonance imaging can be used to confirm the diagnosis. Conservative management with broad-spectrum antibiotics is effective and can be considered the first-line therapy for pediatric renal abscess.

Objective:To explore the factors influencing adherence to voice therapy among patients with voice disorders in China. Methods:Patients with voice disorders who visited the Voice Therapy Center at Sun Yat-sen Memorial Hospital, Sun Yat-sen University, from February to May 2022 were enrolled in the study. Adherence was assessed using the URICA-Voice scale, while influencing factors were assessed through the Voice Handicap Index（VHI） scale and a general information questionnaire. Correlation analysis was conducted using univariate and multivariate logistic regression analysis. Results:A total of 247 patients were included in the study, comprising 57 males（23.08%） and 190 females（76.92%）. The results revealed that: ①Female patients demonstrated higher likelihood of being in the contemplation stage（OR=0.22） compared to males. ②Patients with a monthly family income per capita>6 000 yuan were more likely to be in the contemplation stage than those with<3 000 yuan with an OR = 13.94. ③High vocal-demand occupations increased contemplation stage probability（OR=7.70） compared to moderate-demand occupations. ④Residence within 30-minute commute predicted action/maintenance stages（OR=7.14） versus≥60-minute commute. ⑤Patients whose occupations had high voice demands were more likely to be in the action and maintenance stages than those with average voice demands, with an OR of 16.20. Conclusion:Gender, monthly family income per capita, occupational voice demands, and distance to the hospital significantly impact the URICA-Voice compliance stages of patients. Patients who are female, have higher family income, have occupations with high voice demands, and live closer to the hospital exhibit higher compliance with voice training.
