Traditional Chinese medicine （TCM） offers a rich theoretical foundation and clinical experience for the prevention and treatment of cardiovascular-kidney-metabolic syndrome（CKM）， demonstrating unique advantage. Building on previous work in managing diabetes， its complications， and chronic kidney disease， our team has proposed a five-phase evolution theory of "constraint， heat， deficiency， stasis， and toxin" as the core pathogenesis. These phases correspond to the pathological progression of constraint of phlegm-dampness， constraint transforming into heat， heat damaging qi and yin， stasis accumulated in the collateral vessels， and toxin induced by deficiency and stasis. In the prevention and treatment of CKM by TCM， it is emphasized to integrate the concept of "treating disease before it arises" with constitution theory， and incorporate the "2-5-8" prevention and treatment strategy， which combines prevention with treatment， tailors interventions to different phases， and employs comprehensive treatment modalities. Our goal is to leverage TCM's holistic advantages in preventing and treating CKM.

Objective: To explore the clinical features, treatment and prognosis of emphysematous pyelonephritis (EPN), so as to enhance the clinical awareness of this disease. Methods: A retrospective analysis was conducted on the clinical data of one EPN patient at The Second Affiliated Hospital, Guangzhou University of Chinese Medicine, and a literature review was performed on articles published in the China National Knowledge Infrastructure and PubMed databases from Jan.1, 2015 to Dec.31, 2024. Results: The patient, a 62-year-old male with a 5 years' history of type 2 diabetes, was admitted due to left flank pain for 4 days, with a temperature of 39.4 ℃.Laboratory tests indicated significantly elevated inflammatory markers, decreased platelet count, and abnormal coagulation function.Preoperative blood and urine cultures showed positivity for Escherichia coli.Computed tomography (CT) revealed complete erosion of the left kidney, with gas in the left ureter and surrounding effusion, as well as multiple free gas in the abdominal cavity, bilateral ureteral stones, right renal lower calyx stones.After a multidisciplinary consultation, he underwent emergency phase Ⅰ left pyeloplasty and perirenal drainage with ureteral stenting.After discharge, the patient received maintenance hemodialysis once every two days in the outpatient clinic.One week after-discharge, the patient was readmitted due to polypnea.Following symptomatic management, vital signs stabilized.Approximately 2 months after the first-stage surgery, ureteroscopic stone extraction was successfully performed.One month after the stone extraction procedure, a follow-up CT showed normalization of the left kidney, renal pelvis and calyces, leading to phase Ⅱ laparoscopic left nephrectomy via the abdominal approach, with postoperative pathology indicating renal necrosis.Among 89 EPN patients reported in 35 articles, the median age was 58(24-92) years old；there were 59（66.3%） females and 30（33.7%） males；fever was the most common clinical symptom (60.7%)；73(82.0%) had diabetes, 12 (13.5%) had urinary tract obstruction；55 (61.8%) were infected with Escherichia coli, and 7 (7.9%) were infected with Klebsiella pneumoniae; 13 died due to ineffective treatmen. Conclusion: EPN presents acutely and progresses rapidly, often leading to misdiagnosis due to the lack of specific early symptoms.Abdominal CT is the preferred imaging modality for rapid diagnosis, and proactive interdisciplinary intervention can improve survival rates, reduce the need for nephrectomy, and enhance prognosis.

Objective To analyze the pollution characteristics of 16 polycyclic aromatic hydrocarbons (PAHs) in atmospheric PM_2.5 in Yanta District and Lianhu District of Xi'an City, and assess their health risks to exposed populations through inhalation pathways. Methods From 2020 to 2022, monitoring sites were set up in Yanta District and Lianhu District of Xi'an City, and PM_2.5 samples were collected regularly every month. The mass concentrations of PAHs were determined. The analysis and evaluation were carried out according to different years, regions, and seasons. The sources of PAHs in the atmosphere were identified by calculating characteristic ratios. Health risk assessments through inhalation routes were conducted for certain polycyclic aromatic hydrocarbons and their total carcinogenic equivalent concentrations. Results The average mass concentrations of PAHs in Yanta District and Lianhu District were 6.38 ng/m³ and 6.06 ng/m³, respectively, with no statistically significant difference (P>0.05). Except for fluoranthene, there was no statistically significant difference in other PAHs between regions (P>0.05). Except for acenaphthylene and anthracene, the concentrations of other PAHs showed a decreasing trend year by year (P<0.05). The total mass concentration of PAHs in both urban areas showed a trend of winter>spring>autumn>summer (P<0.05), and all categories of PAHs showed the highest levels in winter and the lowest levels in summer (P<0.05). The proportion of 5-ring PAHs was the highest in summer, while the proportion of 4-ring PAHs was the highest in winter. The main sources of atmospheric PAHs in the two districts were a mixture of coal combustion, motor vehicle emissions, and biomass burning. The HQ values of benzo[a]pyrene and TEQs in both districts were less than 1. The carcinogenic risk through inhalation pathways for TEQs was 1.15×10^-6, exceeding the acceptable level (1×10^-6). Conclusion The pollution of PAHs in Yanta District and Lianhu District of Xi'an City continues to decrease, with seasonal differences. The main sources are mixed sources of coal combustion, motor vehicle emissions, and biomass burning, and overall PAHs pose a potential carcinogenic risk to residents.

The presence of a positive deep surgical margin in tongue squamous cell carcinoma (TSCC) significantly elevates the risk of local recurrence. Therefore, a prompt and precise intraoperative assessment of margin status is imperative to ensure thorough tumor resection. In this study, we integrate Raman imaging technology with an artificial intelligence (AI) generative model, proposing an innovative approach for intraoperative margin status diagnosis. This method utilizes Raman imaging to swiftly and non-invasively capture tissue Raman images, which are then transformed into hematoxylin-eosin (H&E)-stained histopathological images using an AI generative model for histopathological diagnosis. The generated H&E-stained images clearly illustrate the tissue's pathological conditions. Independently reviewed by three pathologists, the overall diagnostic accuracy for distinguishing between tumor tissue and normal muscle tissue reaches 86.7%. Notably, it outperforms current clinical practices, especially in TSCC with positive lymph node metastasis or moderately differentiated grades. This advancement highlights the potential of AI-enhanced Raman imaging to significantly improve intraoperative assessments and surgical margin evaluations, promising a versatile diagnostic tool beyond TSCC.

OBJECTIVE: Benzylisoquinoline alkaloids (BIAs) have pharmacological functions and clinical use. BIAs are mainly distributed in plant species across the order Ranunculales and the genus Phellodendron from Sapindales. The BIA biosynthesis has been intensively investigated in Ranunculales species. However, the accumulation mechanism of BIAs in Phellodendron is largely unknown. The aim of this study is to unravel the biosynthetic pathways of BIAs in Phellodendron amurens. METHODS: The transcriptome and metabolome data from 18 different tissues of P. amurense were meticulously sequenced and subsequently subjected to a thorough analysis. Weighted gene co-expression network analysis (WGCNA), a powerful systems biology approach that facilitates the construction and subsequent analysis of co-expression networks, was utilized to identify candidate genes involved in BIAs biosynthesis. Following this, recombinant plasmids containing candidate genes were expressed in Escherichia coli, a widely used prokaryotic expression system. The purpose of this genetic engineering endeavor was to express the candidate genes within the bacteria, thereby enabling the assessment of the resultant enzyme activity. RESULTS: The synonymous substitutions per synonymous site for paralogs indicated that at least one whole genome duplication event has occurred. The potential BIA biosynthetic pathway of P. amurense was proposed, and two PR10/Bet v1 members, 14 CYP450s, and 33 methyltransferases were selected as related to BIA biosynthesis. One PR10/Bet v1 was identified as norcoclaurine synthase, which could catalyze dopamine and 4-hydroxyphenylacetaldehyde into (S)-norcoclaurine. CONCLUSION Our studies provide important insights into the biosynthesis and evolution of BIAs in non-Ranunculales species.

Objective To evaluate the role of quantitative flow ratio(QFR)in percutaneous coronary intervention(PCI)by using regadenoson stress dynamic single-photon emission computed tomography(D-SPECT).Methods We selected 200 patients with unstable angina admitted to Department of Cardiology,Hebei Medical University First Hospital,from June 31,2021 to June 31,2023 for elective PCI.The patients were aged 57.56±8.23 years and were randomly divided into a conventional group(n=100)and a QFR group(n=100)according to a random number table.The trial was conducted using a double-blind method.The conventional group received PCI treatment based on the experience of the physician,while the QFR group received PCI treatment based on the QFR measurement results.All enrolled patients underwent pre-operative and 7-day post-operative D-SPECT stress imaging using regadenoson stress D-SPECT,and their images were acquired from short axis,vertical long axis,and horizontal long axis to calculate the total myocardial perfusion score and the total myocardial ischemia segment number under the distribution of 17 myocardial segments.Results There was no significant difference in the number of myocardial ischemia segments(7.59±3.14 vs.7.48±3.36,P=0.811)or the total myocardial perfusion score(15.87±7.61 vs.15.63±5.97,P=0.860)between the two groups before PCI.The number of myocardial ischemia segments(5.58±3.36 vs.6.51±2.14,P=0.020)and the total myocardial perfusion score(10.55±4.41 vs.12.96±6.50,P=0.002)in the QFR group were significantly better than those in the conventional group 7 days after PCI(P＜0.05).Conclusion Applying QFR guidance for PCI can better improve the degree of myocardial ischemia in patients.

Objective To evaluate the application value of artificial intelligence mixed reality(AI-MR)technology in the planning of ultrasound-guided percutaneous nephrolithotomy(PCNL)for special types of complex upper urinary stones.Methods The prospective single-center,single-arm clinical study involved 15 patients with complex upper urinary stones undergoing ultrasound-guided PCNL during Aug.2022 and May 2023,including 9 male and 6 female,3 cases of pelvic ectopic kidney stones,5 cases of horseshoe kidney stones,3 cases of renal stones combined with spinal deformity,and 4 cases of transplant kidney stones.Based on preoperative computed tomography urography(CTU)data,digital three-dimensional reconstruction was performed,and AI-MR was used to project surgery-related three-dimensional images in real space to obtain"perspective"information of the surgical area.This facilitated preoperative design and planning,including target calyx,number of channels,and auxiliary measures.The compliance of target calyx and number of channels,stone clearance rate,total operation time,time required to establish the percutaneous renal channel,decrease in hemoglobin level,surgical complications,and postoperative hospital stay were analyzed.Results All 15 patients underwent preoperative planning using AI-MR and successfully completed one-stage ultrasound-guided PCNL.Based on the preoperative planning,we utilized S-PCNL alone or combined with Needle-perc or antegrade/retrograde FURS/RIRS.Among all patients,4 underwent single-channel S-PCNL,3 multi-channel S-PCNL,and 8 S-PCNL combined with Needle-perc or FURS.The compliance of target calyx and number of channels was 86.7％,the one-stage stone clearance rate was 80.0％,the average time for establishing the channel was(2.3±0.3)minutes,the average total operation time was(61.5±12.2)minutes,the mean decrease in hemoglobin level was(9.6±1.2)g/L,and the average postoperative hospital stay was(4.6±0.5)days.There were no Clavien-Dindo grade ≥ Ⅱ complications,such as blood transfusion,organ injury,or urosepsis.Conclusion Before surgery,AI-MR can be used to quantitatively analyze imaging data for patients with special types of complex upper urinary stones,which can achieve three-dimensional fluoroscopy effects,formulate surgical plans,optimize puncture paths,effectively avoid the risk of damage to surrounding organs,reduce complications,shorten treatment cycle and improve the first-stage stone clearance rate.

While biological identification technology has brought positive impacts to society,it has also raised ethical issues,such as privacy protection and fair application.Taking the technical dimension as the main line is the foundation of efficient and agile governance of ethical issues in biological identification technology.Based on the technology track theory,a framework for ethical governance of biological identification technology was constructed,and the track and ethical governance technology of biological identification technology were sorted out.The key to efficient governance lies in the application of ethical governance technologies such as privacy and security protection and fairness detection at the three levels of the entire lifecycle of biological identification technology,including data,algorithms,and systems.Taking Hikvision's facial recognition technology as an example,this paper elaborated that increasing the application of ethical governance technology is of great significance to ensure the trustworthy and sustainable development of biological identification technology.
