Objective:To explore the clinical application value of artificial intelligence(AI)-assisted training in enhancing the accuracy of nuchal translucency(NT)identification,standardization of measurement,and diagnostic efficacy for abnormalities among ultrasound residents.Methods:A retrospective collection of 300 standard fetal NT ultrasound images was conducted at the Center for Medical Ultrasound,Suzhou Hospital Affiliated of Nanjing Medical University from January 2018 to June 2024. The AI model performed NT measurements and diagnoses once. Four sonographers of different seniority levels(including two resident physicians)independently conducted NT measurements and diagnoses twice. Prior to the experiment,the middle-age and resident sonographers had uniformly completed traditional theory training. Following the first independent measurements,the two resident sonographers received additional AI-assisted training,after which all 4 sonographers performed the second independent measurements. A fetal medicine expert evaluated blindly all the results and compared the differences in NT recognition accuracy,measurement standard rate and diagnosis accuracy between the middle-age sonographer(traditional training only)and two resident sonographers(traditional + AI-assisted training).Results:For the middle-aged sonographer who only received traditional lecture-based training,the accuracy of NT recognition,standardization rate of measurement,or diagnostic accuracy were not significantly improved befroe and after the training,and the diffrence was not statistically significant( χ2=0.189,1.887,0.326;all P>0.05). In contrast,the second-year resident(Resident 2)and first-year resident(Resident 1),who received both traditional lecture-based training and AI training,demonstrated some improvements in the accuracy of NT measurement site recognition,though the differences were not statistically significant( χ2=1.301,2.418;all P>0.05). However,both residents did significant improvements in the standardization rate of NT measurement( χ2=25.768,17.035;all P<0.05). In terms of diagnostic accuracy,Resident 1 did significant improvement( χ2=10.180, P<0.05),while Resident 2 also did some improvement,though the difference was not statistically significant( χ2=2.573, P>0.05). Conclusions:The AI-assisted training system enhances the ability of ultrasound resident sonographers to recognize,measure,and diagnose NT,providing a novel and efficient training model for standardized residency training in ultrasound specialties.

Objective:To investigate the diagnostic value of fetal cardiac ultrasound view visualization in the first trimester for congenital heart disease(CHD).Methods:A retrospective analysis was performed on 13 323 singleton fetuses who underwent first-trimester(11-13 +6 weeks)ultrasound screening at the Ultrasound Medicine Center,the Affiliated Suzhou Hospital of Nanjing Medical University from January 2018 to June 2024. Cardiac views including the four-chamber view(4CV),left ventricular outflow tract view(LVOT),and Results:The study group showed significantly higher rates of "poorly visualized" 4CV,LVOT,and 3VT than the control group(2.70% vs. 0.14%, P=0.005;36.49% vs. 4.76%, P<0.001;36.49% vs.2.46%, P<0.001). The efficacies of combination 1(any view abnormal)and combination 2(any view "poorly visualized" or "abnormal")were comparable,with AUCs of 0.86 and 0.85( P=0.424). The AUCs of combination 3(3VT "poorly visualized" or any view "abnormal")and combination 4(4CV "poorly visualized" or any view "abnormal")were 0.88 and 0.86( P=0.424),all significantly higher than combination 5(LVOT "poorly visualized" or any view "abnormal",AUC=0.84,all P<0.05). Conclusions:"Poorly visualized" cardiac views in the first trimester demonstrate good diagnostic efficacy for CHD,particularly when 3VT or 4CV are affected,warranting heightened clinical vigilance for fetal cardiac anomalies.

Hepatic fibrosis is a pathological process of chronic liver injury. Without timely intervention and treatment, liver fibrosis may eventually lead to liver cirrhosis and cancer. Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathway is closely associated with the occurrence and development of liver fibrosis. Based on this, this paper summarized and analyzed the mechanism and effects of active ingredients and compounds of traditional Chinese medicine improving liver fibrosis based on JAK/STAT signaling pathway. It is found that the active ingredients and compounds of traditional Chinese medicine that promote blood circulation and remove blood stasis (ingredients such as ethanol extract of Euonymus alatus and paclitaxel, as well as compounds such as Ershiwuwei songshi pill and Ganfukang), clear away heat and toxic material (ingredients such as betulinic acid, total flavonoids from Persicaria perfoliata, as well as compounds such as Pianzaihuang and Kehuang capsules), and sooth the liver and promote qi circulation (ingredients such as fraxetin and cucurbitacin B, as well as compounds such as Chaihu shugan powder and Xiaochaihu decoction) can all relieve liver fibrosis by inhibiting the activity of the JAK/STAT signaling pathway, reducing inflammatory reactions, and inhibiting the proliferation of hepatic stellate cells.

Objective:To investigate the mid- and long-term training effect of deliberate practice combined with intensive training in cardiopulmonary resuscitation (CPR) teaching for nurses receiving standardized training.Methods:A total of 160 nurses who received the first year of standardized training in Guangdong Provincial Hospital of Traditional Chinese Medicine from July 2020 to March 2021 were enrolled as subjects, and they were randomly divided into experimental group and control group, with 80 nurses in each group. The nurses in the control group received the mode of single deliberate practice, and those in the experimental group received deliberate practice combined with intensive training at months 0, 3, and 6. Assessment was performed for the two groups before and after training,with objective indicators and subjective evaluation as the assessment criteria. Objective score was determined by the immediate objective feedback provided by the electronic display of Resusci Anne ? QCPR, and subjective score was determined by the same group of examiners based on the evaluation of cardiopulmonary resuscitation performed by trainees,including environment evaluation, judgment of consciousness, judgment of respiration, initiation of emergency treatment system, re-evaluation after resuscitation, and overall evaluation. SPSS 18.0 was used for the independent samples t-test, the non-parametric test, and the chi-squares test. Results:After training, there were significant differences between the experimental group and the control group in the objective indicators of the percentage of correct compression (CC%) [85.500 (77.50, 93.00) vs. 81.00 (71.75, 89.00), Z=-2.49, P=0.013] and the proportion of correct ventilation (V%) [84.00 (75.00, 92.75) vs. 80.00 (64.00, 90.25), Z=-2.15, P=0.031]. Both groups had significant improvements in objective and subjective indicators after training (all P<0.05). Conclusions:Deliberate practice combined with intensive training at an interval of 3 months can effectively improve the mid- and long-term CPR skills of nurses receiving standardized training and is more suitable for high-level muscle memory training.

OBJECTIVE:
To evaluate the efficacy of Wen-Luo-Tong Granules (WLT) local administration in the treatment of patients with peripheral neuropathy (PN) induced by chemotherapy or target therapy.
METHODS:
This study is a randomized, double-blinded, and placebo-controlled trial. Seventy-eight patients with PN induced by chemotherapy or target therapy were enrolled from China-Japan Friendship Hospital between July 2019 and January 2020. They were randomly assigned to WLT (39 cases) and control groups (39 cases) using a block randomization method. The WLT group received WLT (hand and foot bath) plus oral Mecobalamin for 1 week, while the control group received placebo plus oral Mecobalamin. The primary endpoint was PN grade evaluated by the National Cancer Institute-Common Toxicity Criteria for Adverse Events (NCI-CTCAE). The secondary endpoints included quantitative touch-detection threshold, neuropathy symptoms, Quality of Life Questionnaire-Chemotherapy Induced Peripheral Neuropathy (QLQ-CIPN20), and Quality of Life Questionnaire-Core30 (QLQ-C30).
RESULTS:
After treatment, the PN grade in the WLT group was significantly lower than that in the control group (1.00 ± 0.29 vs. 1.75 ± 0.68, P<0.01). The total effective rate in the WLT group was significantly higher than that in the control group (82.05% vs. 51.28%, P<0.01). Compared with the control group, the touch-detection thresholds at fingertips, neuropathy symptom score, QLQ-CIPN 20 (sensory scale, motor scale, autonomic scale, and sum score), and QLQ-C30 (physical functioning, role functioning, emotional functioning, and global health) in the WLT group significantly improved after treatment (P<0.01 or P<0.05).
CONCLUSION
WLT local administration was significantly effective in the treatment of patients with PN induced by chemotherapy or target therapy. (Trial registration No. ChiCTR1900023862).

Objective:To investigate the incidence of acute kidney injury (AKI) following cardiac surgery and related risk factors in 4 878 patients.Methods:The information from patients who underwent cardiac surgery through March 2015 to October 2015 was collected retrospectively from the electronic database of Beijing Anzhen Hospital. A total of 4 878 patients were divided into AKI group and non-AKI group according to whether AKI occurred within 7 days after cardiac surgery. The incidence of AKI was calculated, and the AKI incidence in different types of cardiac surgeries were compared. Clinical data such as baseline clinical information, operation information, comorbidity, hospital stay time, life ability score in discharge from the hospital, and so on, were compared between AKI group and the non-AKI group using univariate analysis. Risk factors for AKI following cardiac surgery were analyzed using the binary multivariate logistic regression.Results:A total of 933 patients suffered from AKI (19.1%) following cardiac surgery. The time of stay in the hospital was longer in AKI group than that in the non-AKI group [(14.4±8.9) vs (13.7±7.7) d, P<0.05)]. The incidence of AKI in different types of cardiac surgeries varied significantly ( P<0.001). The logistic regression analysis showed that male, diabetes, hypertension, the elevated basic serum creatinine, cardiac dysfunction (NYHA grade≥Ⅲ), cardiopulmonary bypass, a combination of operations≥3, the rethoracotomy exploration and hemostasia, and using an invasive ventilator for over 96 hours were the independent risk factors for the AKI following cardiac surgery (all P<0.05), and the odds ratio (95% confidence interval) were 1.81(1.46-2.24), 1.29(1.03-1.62), 5.85(4.73-7.22), 1.81(1.36-2.40), 4.49(3.60-5.60), 1.84(1.49-2.27), 23.24(18.25-29.59), 2.34(1.45-3.77) and 1.94(1.09-3.43) respectively. Conclusions:The incidence of AKI after cardiac surgery in Beijing Anzhen Hospital is 19.1%. AKI following cardiac surgery prolongs the time of stay in the hospital. Independent risk factors for AKI following cardiac surgery are multiple, and one of the most critical factors is a combination of operations≥3.
