Traditional four examinations of traditional Chinese medicine （TCM） are based on the symptoms and signs of patients， which are the advantages of TCM but also have shortcomings. Chronic kidney disease has the characteristics of insidiousness， long-term， deficiency and variability during its onset， which are difficult to be intervened in time based on only symptoms， therefore it is necessary to extend the application of the four examinations in the diagnosis and treatment process of chronic kidney disease. Based on the background of the continuous development of TCM syndrome differentiation techniques， this article proposed the extension and application strategies of the traditional four examinations in chronic kidney disease， including the incorporation of microscopic syndrome differentiation to identify the causes of kidney disease and prevent symptom deterioration； the utilization of accurate examination information enhanced by artificial intelligence for controlling development of existing disease； the integration of disease differentiation and syndrome differentiation to summarize clinical rules towards using constant to measure variation； and the establishment of a kidney disease database for the storage of four examinations information to prevent recurrence after recovery. The four above extension and application strategies can be used to achieve the long-term management and treatment effects of timely and early diagnosis， dynamic observation of the condition， accurate application of intervention， and strengthened prognosis assessment in the diagnosis and treatment of chronic kidney disease， and expand the advantages of TCM in the prevention and treatment of chronic kidney disease.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

OBJECTIVE: To accurately measure human energy metabolism with high temporal resolution, a respiratory gas analysis system was designed using a breath-by-breath approach. METHODS: Firstly, indirect calorimetry was employed in respiratory gas analysis to measure the respiratory flow and concentration signals in real-time. Secondly, oxygen consumption QO2 and carbon dioxide production QCO2 were calculated through respiratory characteristic alignment and respiratory signal segmentation. Finally, metabolic indexes were calculated according to the Weir formula. Furthermore, a controlled trial was formulated for validation comparisons with the MGC ULTIMA SYSTEM PFX CARDIO2. RESULTS: The results indicate that the data points of metabolic indexes measured by this system all fall within the confidence interval when compared with those of the MGC. CONCLUSION The system has high consistency with the MGC measurement results. Thus, the system can accurately measure metabolism in real-time and provide data support for clinical nutrition assessment and therapy.

Objective:This study aims to explore the risk factors of Multi-center Investigator-Initiated Clinical Trials (MIITs), and provide a basis for developing study management strategies.Methods:The original draft of MIIT risk evaluation factors was determined through literature analysis and internal discussions of the research group. Thirty five experts were consulted using the Delphi method, and then the MIIT risk evaluation elements were finally determined. Analytic Hierarchy Process (AHP) was used to calculate the weights of each index.Results:The recovery rates of both rounds of expert consultation were 100%, and the degree of expert authority was 0.856. The study ultimately formed an MIIT risk evaluation framework consisting of three first-class indexes, twelve second-class indexes, and thirty-eight third-class indexes. The weight values of the first-class indexes (start-up period, implementation period, and summary period) were 0.209 8, 0.710 6, and 0.079 6, respectively. Meanwhile, the weight values of the second-class indexes and third-class indexes were determined.Conclusions:Exploring the risk evaluation factors of MIIT provides valuable insights into identifying critical risk points, which, in turn, contributes to enhancing MIIT management efficiency, research progress, and quality.

Objective·To investigate the imaging features of computed tomography(CT)and magnetic resonance imaging(MRI)in the patients with Kimura disease(KD)in the head and neck.Methods·Sixty-four cases of KD in the head and neck comfirmed by histopathology were retrospectively collected from 2009 to 2023 in Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine.All patients completed CT and/or MRI enhancement imaging before surgery.Clinical and imaging characteristics were collected,recorded and analyzed,including age,gender,peripheral blood eosinophilic ratio,serum IgE level,the lesion location,shape,size,CT density and degree of enhancement,MRI signal intensity and degree of enhancement,apparent diffusion coefficient(ADC),time-signal intensity curve(TIC)patterns,wash-in rate,and time to peak(TTP).Results·The average age of the 64 KD patients was(40±19)years,and 92.2%were males.A total of 73.5%of the patients showed an elevated ratio of peripheral blood eosinophil,and all 10 tested patients exhibited increased serum IgE levels.There were 82 extranodal(subcutaneous and glandular)lesions and 144 lymph node lesions detected by CT and MRI.Among the extranodal lesions,80.5%were subcutaneous or glandular patchy lesions with unclear boundaries,and the rest were nodular lesions with clear boundaries.All lesions exhibited isodensity on CT scans and showed isointensity on T1-weighted imaging(T1WI)and hyperintensity on T2-weighted imaging(T2WI)in MRI.Most extranodal lesions tended to show heterogeneous enhancement,while most lymph node lesions showed homogeneous enhancement.The median ADCs of the extranodal lesions and the lymph node lesions were 1.04×10-3 mm2/s and 0.67×10-3 mm2/s,respectively,which were significantly different(P=0.000).The dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)results showed that the TIC patterns of extranodal lesions were predominantly type Ⅰ andⅡ,accounting for 57.5%and 42.5%,respectively;while the TIC patterns of lymph node lesions were predominantly type Ⅱ(96.6%).The difference in the TTP and the wash-in rate between the extranodal lesions and the lymph node lesions were both statistically significant(P=0.000).Conclusion·Extranodal lesions and lymph node lesions of KD both show isodensity on CT,and isointensity on T1WI and hyperintensity on T2WI in MRI.Extranodal lesions often show high ADC,TIC type Ⅰ or Ⅱ,and mostly heterogeneous enhancement;lymph node lesions often show low ADC,TIC type Ⅱ,and mostly homogenous enhancement.

Objective:To construct a whole course management and follow-up platform, named Care Plan, for patients undergoing breast reconstruction surgery, and to evaluate its initial clinical applications.Methods:From June 2023 to January 2024, patients who underwent breast reconstruction surgery at Peking Union Medical College Hospital were selected as the study subjects and enrolled in the Care Plan platform for whole course management. The platform comprised five modules: patient education, self-assessment, medical assessment, medical follow-up, and doctor-patient dialogue, each with corresponding sub-modules and specific components. Each patient was assigned to a case manager who provided one-on-one assessment, sent patient education materials, and conducted follow-ups. The preliminary application of the Care Plan platform was evaluated based on the completeness of patient data, patient education material reading status, doctor-patient dialogue topics, and follow-up responses. At 3 months postoperatively, patients were followed up and further divided into patient education group(reading at least an article on patient educational materials) and control group based on their reading status of educational materials. Patients rated their satisfaction with the surgery using a 5-point questionnaire, including five indicators: expected breast reconstruction outcome, expected surgical type, completeness of information acquisition, breast symmetry, and breast softness. Statistical analysis was performed using SPSS 27.0.1 software, with count data expressed as frequencies and (or) percentages, normally distributed measurement data expressed as Mean±SD, intergroup comparisons conducted using t-test, and P<0.05 indicating statistical significance. Results:A total of 147 female patients aged 16 to 63 years with a body mass index of 16.6 to 31.3 kg/m 2 were ultimately included. All 147 patients completed the content of the self-assessment and medical assessment modules, with relatively complete data. Of the 133 patients who received patient education materials sent through the platform, 38 (28.6%) read the materials, with the sub-module on the introduction and choices of the reconstruction surgery (37.3%, 94/252 ) being the most frequently viewed. A total of 24 patients (16.3%, 24/147 ) raised 45 questions using the doctor-patient dialogue module, with the highest proportion related to consultation issues and complications, each accounting for 22.2% (10/45). Twenty-three patients completed the 3-month follow-up, with 12 in the patient education group and 11 in the control group. The patient education group scored higher than the control group in terms of completeness of information acquisition [(4.58±0.51) points vs. (3.91±0.70) points, t=-2.65, P=0.015], while scoring lower in breast symmetry [(3.92±0.79) points vs. (4.63±0.67) points, t=2.33, P=0.030]. There was no significant difference between the two groups in terms of expected breast reconstruction outcome, expected surgical type, and breast softness scores ( P>0.05 for all). Conclusion:The Care Plan platform for whole course management and follow-up of breast reconstruction can assist medical staff in formulating patient-centered management plans, improve patients’ understanding of surgical information, and aid patients in making decisions regarding breast reconstruction methods.
