Objective To systematically evaluate the efficacy and safety of traditional Chinese medicine (TCM) compound in treating pulmonary nodules, providing evidence-based medical evidence for TCM intervention in pulmonary nodules. Methods Computer search of PubMed, CNKI, Wanfang, VIP, and SinoMed was conducted to select randomized controlled trials (RCTs) of TCM compound intervention in pulmonary nodules, with the retrieval time from the inception to November 29, 2023. The Cochrane bias risk assessment tool was used to evaluate the quality of the included studies, and Review Manager 5.4 was used for Meta-analysis. Results A total of 18 RCTs were included, covering 8 provinces across the country, with a total sample size of 1301 patients. The TCM compounds used in the included studies all incorporated the method of dissolving phlegm and dissipating nodules. There was a high risk of bias uncertainty in the included studies. Meta-analysis results suggested that TCM compound could significantly reduce the diameter of pulmonary nodules [MD=−1.41, 95%CI (−1.70, −1.13), P<0.001], decrease the number of nodules [MD=−0.37, 95%CI (−0.73, −0.01), P=0.05], alleviate clinical symptoms [MD=−4.84, 95%CI (−6.04, −3.64), P<0.001], and improve lung function [forced expiratory volume in one second (FEV1), MD=0.55, 95%CI (0.09, 1.01), P=0.02; FEV1/forced vital capacity, MD=6.12, 95%CI (4.47, 7.78), P<0.001]. However, there was no statistically significant difference in the probability of malignancy between the experimental group and the control group [MD=−0.01, 95%CI (−0.01, 0.00), P=0.09]. Conclusion TCM compound can significantly reduce the diameter of pulmonary nodules, decrease the number of nodules, alleviate clinical symptoms, and improve lung function, but future multicenter, large-sample, high-quality RCTs are still needed to further explore and verify this conclusion.

ObjectiveTo systematically compare the efficacy of different non-invasive brain stimulation (NIBS) techniques on balance function in stroke patients via network meta-analysis. MethodsPubMed, Embase, Web of Science, Cochrane Library, Scopus and CNKI were systematically searched from database establishment to February, 2026. Randomized controlled trials (RCTs) and randomized crossover designs (RCDs) investigating NIBS for post-stroke balance impairment were enrolled. The Cochrane risk of bias assessment tool was used for risk-of-bias assessment; RevMan 5.4 was used for sensitivity analysis, and Stata 18.0 for subgroup analysis and network meta-analysis. ResultsA total of 35 eligible studies (31 RCTs, 4 RCDs) involving 1 226 stroke patients were included. No NIBS modalities might significantly improve the outcome of Timed Up and Go Test, while the effect of transcranial direct current stimulation (tDCS) ranked first on Berg Balance Scale score (SUCRA = 85.9%). Subgroup analyses indicated superior balance benefits in interventions targeting primary motor cortex, with stimulation intensity of 80% to 100% RMT and disease courses ≤ 6 months. ConclusiontDCS may be an optimal intervention for comprehensive balance function after stroke.

[Objective] To compare the diagnostic accuracy of three imaging modalities, inlducing CT urography (CTU), contrast-enhanced MRI (CE-MRI), and contrast-enhanced ultrasound (CEUS) in the qualitative diagnosis of renal space-occupying lesions. [Methods] A retrospective analysis was performed on 542 patients with renal lesions confirmed by surgical pathology in our hospital during Jan.2019 and May 2024.The diagnostic results of CTU, CE-MRI and CEUS were compared and analyzed based on the patients' clinical and pathological data. [Results] The diagnostic accuracy rate of CTU, CE-MRI and CEUS were 84.50%, 83.14% and 86.14%, respectively.For the 161 patients who underwent all three examinations, CEUS was significantly more accurate than CTU (84.16% vs. 77.02%, P=0.018), while there was no significant difference between CTU or CEUS and CE-MRI (79.81%) (P>0.05). Further analysis found that for lesions ≤4 cm, the accuracy of the three examinations was as follows: CEUS=CTU 79.55%, CE-MRI 76.14%, with no significant difference (P>0.05). However, for lesions >4 cm, CEUS ranked the first, followed by CE-MRI and CTU (89.73% vs. 84.25% vs. 73.97%), and CEUS and CE-MRI were better than CTU (P<0.05). Additionally, for the diagnosis of clear cell renal carcinoma and benign renal space-occupying lesions, there was no statistically significant difference among the three imaging modalities (P>0.05), while for the qualitative diagnosis of non-clear cell renal carcinoma, CEUS ranked the first, followed by CE-MRI and CTU (83.87% vs. 74.19% vs. 56.45%), and CE-MRI and CEUS were better than CTU (P<0.05). [Conclusion] All of them have important diagnostic value, and the appropriate selection should be based on patients' specifc conditions.CEUS and CE-MRI are more accurate in the qualitative diagnosis of renal space-occupying lesions than CTU, especially for large lesions and non-clear cell carcinoma.

Objective:To investigate the nutritional risk status of children in PICU and analyze its influencing factors.Methods:From July 2021 to February 2023,all children aged 1 to 18 years admitted to PICU of Beijing Children's Hospital were investigated by using the pediatric Yorkhill Malnutrition Scoring tool(PYMS)and the clinical data questionnaire.Results:A total of 492 children in PICU were enrolled.The first nutritional risk screening results showed that there were 32 cases of no/low nutritional risk(6.5%),76 cases of medium risk(15.4%),and 384 cases of high risk(78.1%).The incidence of medium/high nutritional risk was as high as 93.5%.The PYMS score of nutritional risk in PICU was(2.61±1.42).The results of multiple linear regression analysis showed that weight,fever time before admission,white blood cells,body mass index,primary diagnosis,father's education,and diet before illness were the main influencing factors of nutritional risk of children in PICU(P<0.05).Conclusion:Children in PICU are in a state of high nutritional risk.It is suggested that children in PICU should carry out nutritional screening in a standardized manner,identify children with high nutritional risk and its influencing factors early.To actively conduct nutritional assessment and nutritional intervention could improve the clinical outcome of children in PICU.

Objective:To investigate the differences in resistance to chemical disinfectants between bacteriophage Phi-X174 and disinfection effect indicator microorganisms, Staphylococcus aureus and Escherichia coli. Methods:Three commonly used disinfectants, including chlorine-containing disinfectants, alcohol-based disinfectants and quaternary ammonium salt disinfectants, were selected to analyze the differences in resistance of phage Phi-X174, Staphylococcus aureus and Escherichia coli by using the quantitative sterilization test of suspension. Results:The 250 mg/L sodium dichloroisocyanurate solution treated for 10 minutes yielded log reduction values of 3.39, 7.25 and 7.37 against phage Phi-X174, Staphylococcus aureus and Escherichia coli respectively. The 40% ethanol for 1 minute yielded log reduction values of 0.03, 2.46 and 7.30 against phage Phi-X174, Staphylococcus aureus and Escherichia coli, respectively. The 100 mg/L benzalkonium chloride for 10 minutes yielded log reduction values of 1.41, 6.84 and 0.93 for phage Phi-X174, Staphylococcus aureus and Escherichia coli, respectively. Conclusion:Phage Phi-X174 has stronger resistance to chlorine-containing disinfectants and alcohol-based disinfectants than Escherichia coli and Staphylococcus aureus. Its resistance to quaternary ammonium salt disinfectants is between that of Staphylococcus aureus and Escherichia coli.

Objective:To investigate the relationship between epicardial adipose tissue (EAT) and frequent premature ventricular contractions (PVC) based on no-contrast chest CT scanning and evaluate the predictive value of EAT for high PVC loading levels.Methods:A case-control study was conducted to collect patients with PVC from January 2021 to June 2023 in the First Affiliated Hospital of Xinjiang Medical University. The study subjects were divided into a PVC high-load group (≥20%) and a PVC low-load group (<20%) based on the level of PVC loading in the 24-hour Holter electrocardiography monitoring. The parameter characteristics of EAT were obtained from no-contrast chest CT images. Multivariate logistic regression model analysis was used to assess the factors associated with high PVC loading levels, and the receiver operating characteristic (ROC) curve was used to assess the predictive value of the model.Results:A total of 166 subjects were included in the study, including 50 in the PVC high-load group and 116 in the PVC low-load group. Compared with the PVC low-load group, EATV was significantly increased in the high-load group ( Z=4.83, P<0.001), and EATA was significantly lower in the high-load group than in the low-load group ( t=-3.95, P<0.001). However, there was no statistically significant difference for the comparison of EATD ( Z=-1.56, P=0.120). Multivariate logistic regression model analysis showed that high EATV and low EATA were factors of high PVC loading levels [EATV: OR=1.01 (95% CI: 1.00-1.02), EATA: OR=1.16 (95% CI: 1.02-1.32)]. The area under the ROC curve for predicting high PVC loading levels by EATV and EATA was 0.79 (95% CI: 0.71-0.86). Conclusion:EATV and EATA are factors of high PVC loading levels and have predictive value for high PVC loading levels.
