To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

[Objective] To explore the diagnosis and treatment experience of tension hydrocele. [Methods] The clinical data of 2 patients with tension hydrocele treated in our hospital were retrospectively analyzed.Relevant literature was retrieved to analyze the clinical characteristics of this disease. [Results] Case 1 was diagnosed due to swelling and pain of the left scrotum after trauma for more than one month, which worsened for one day.Physical examination showed high tension in the left scrotum and positive light transmission test.Ultrasound examination revealed that the blood flow signal in the left testis disappeared.Emergency left scrotal exploration and hydrocelectomy were performed.There was no sign of testis torsion during the operation.Case 2 was diagnosed mainly due to hydrocele of the right testis for 1 year, which worsened for 1 week and complicated with testis distension and pain.Physical examination showed high tension in the right scrotum and positive light transmission test.Ultrasound examination revealed that the blood flow signal in the right testis decreased.After 40ml of fluid was extracted under ultrasound monitoring, the blood flow signal in the right testis recovered.Hydrocelectomy was performed the next day.During the follow-up of 8 months, there was no recurrence of hydrocele.A search of domestic and foreign literature showed that there were no reports in domestic literature, while a total of 11 cases were reported in foreign literature. [Conclusion] Tension hydrocele of the testis is a rare emergency of the scrotum.Surgery or decompression should be performed as soon as possible to restore testicular blood supply, and hydrocelectomy should be performed simultaneously or in stages to prevent recurrence.

Objective To develop a rehabilitation nursing model for knee osteoarthritis(KOA)of external treatment in traditional Chinese medicine(TCM).Methods Between February and June 2023,a preliminary KOA rehabilitation nursing model was developed through literature search and semi-structured interview method.Two rounds of Delphi consultations were conducted with the selected experts,to establish a rehabilitation nursing model for KOA of TCM external treatment.Results A total of 24 experts from different regions participated in the consultation.The final rehabilitation nursing model of TCM external treatment for KOA included 3 primary indicators,16 secondary indicators and 91 tertiary indicators.The response rates from the two rounds of expert consultation were 96.00%and 100.00%,respectively,and the rates of expert opinion proposal were 58.33%and 8.33%,respectively.The expert authority coefficient were 0.906 and 0.923.The two rounds of expert consultation were 0.137 and 0.236 in Kendall's coefficient of concordance(W),with statistically significant differences(both P<0.001).The importance scores of each item in the second inquiry ranged from 3.75 to 4.88,and the coefficient of variation ranged from 0.07 to 0.30,and the full score ratio ranged from 20.83%to 87.50%.Conclusion The rehabilitation nursing model for KOA of TCM external treatment developed in this study is significant,scientific and feasible.It provides a guidance for medical professionals.

Objective:To evaluate the safety and oncological outcomes of robot-assisted laparoscopic inferior vena cava(IVC)segmental resection in renal tumor with IVC tumor thrombus(IVCTT).Methods:Clinical data from renal tumor patients undergoing robot-assisted laparoscopic IVC segmental resection at Peking University Third Hospital from Jan.2021 to Feb.2025 were retrospectively analyzed.Data collection included baseline demographics,tumor characteristics,perioperative parameters,and follow-up outcomes.Surgical records and pathological reports were retrieved from the electronic medical record system.Continuous variables were presented as median(P25,P75),and categorical variables as frequency(percentage).Results:Forty-four patients were enrolled.The cohort comprised 31 malesand 13 females,with a median age of 62(55,68)years.Right-sided tumors were observed in 39 cases and left-sided in 5 cases.Median tumor diameter was 8.1(6.1,10.1)cm.Mayo classifications included grade Ⅱ(n=37),Ⅲ(n=6),and Ⅳ(n=1).Neoadjuvant therapy was administered to 23 patients.Seventeen patients were complicated by IVC bland thrombus.Median operative time was 224.0(167.3,303.8)min,with intraoperative blood loss of 500.0(300.0,850.0)mL.Transfusion was administered to 19 patients,with a median blood transfusion of 800.0(400.0,1 200.0)mL.Postoperative complica-tions occurred in 25 cases(56.8％),classified as Clavien-Dindo grade Ⅰ(n=8)and grade Ⅱ(n=17).Procedure-specific complications included deep vein thrombosis(n=6),transfusion-requiring ane-mia(n=5),lower extremity edema(n=2),and pulmonary embolism(n=2),with no procedure-related mortality.Median postoperative serum creatinine was 116.0(86.5,157.5)μmnol/L.Pathological examination identified clear cell renal cell carcinoma as the predominant subtype,observed in 34 cases(77.3％).Pathological staging revealed T3b(n=12),T3c(n=29),and T4(n=3)disease,with nodal involvement(N1)in 8 cases and distant metastasis(M1)in 17.At a median follow-up of 10 months(range:1-49 months),cancer-specific mortality occurred in 3 patients,while 1 succumbed to other causes.Disease progression included pulmonary metastasis(n=5),hepatic metastasis(n=4),and local recurrence(n=4).Adjuvant therapy regimens comprised targeted-immunotherapy combina-tions(n=9)and targeted monotherapy(n=18).Conclusion:Robot-assisted laparoscopic I VC seg-mental resection achieves precise thrombus removal with confirmed short-term efficacy in renal tumor with IVCTT,though vigilance against vascular complications remains critical.

Objective:To compare the clinicopathological characteristics and prognostic outcomes between patients with clear cell renal cell carcinoma(ccRCC)and non-clear cell renal cell carcinoma(nccRCC)accompanied by venous tumor thrombus.Methods:A retrospective analysis was conducted on clinical and pathological data from patients with RCC and venous tumor thrombus treated in the Depart-ment of Urology at Peking University Third Hospital between January 2014 and February 2024.Patients were stratified into two groups based on pathological type:ccRCC and nccRCC.Comparisons of baseline characteristics,intraoperative situation,and prognosis between the two groups were performed using t-tests,Mann-Whitney U tests,chi-square tests,and Log-rank tests.Survival curves were generated using the Kaplan-Meier method.Results:A total of 437 patients were included,with a median age of 58 years,including 317 males and 120 females.The cohort comprised 366 cases of ccRCC and 71 cases of nccRCC.The non-clear cell group included 38 cases(53.5％)of papillary renal cell carcinoma,2 cases(2.8％)of chromophobe renal cell carcinoma,11 cases(15.5％)of unclassified renal cell carcinoma,19 cases(26.8％)of molecularly defined renal cell carcinoma,and 1 case(1.4％)of collecting duct carcinoma.Compared with the clear cell renal carcinoma group,patients in the non-clear cell carcinoma group demonstrated a younger age at diagnosis(59 years vs.55 years,P=0.010),larger tumor size(8.4 cm vs.9.5 cm,P=0.025),higher rates of lymph node metastasis(56.8％vs.70.6％,P=0.034),more advanced tumor thrombus(P＜0.001)and pathological grading(P=0.010),longer surgical duration(272 minutes vs.289 minutes,P=0.023),and shorter overall survival(80 months vs.35 months,P＜0.001).Multivariate Cox analysis indicated that histologic type,distant metastasis,tumor thrombus grading,and sarcomatoid/rhabdoid differentiation were prognostic factors in the renal cell carcinoma patients with venous tumor thrombus.No significant differences were observed between the two groups in terms of gender,body mass index,tumor laterality,distant metastasis,sarcomatoid or rhabdoid differentiation,American Society of Anesthesiologists(ASA)score,surgical approach,conversion to open surgery,blood loss,or transfusion of red blood cells and plasma.Conclusion:Compared with pa-tients with clear cell renal carcinoma and venous tumor thrombus,those with non-clear cell carcinoma and venous tumor thrombus exhibit earlier onset,more aggressive disease progression,and poorer prognosis.

Objective:To review the clinicopathological features of TFE3-rearranged renal cell carcino-ma(TFE3-RCC)with venous tumor thrombus(VT)(TFE3-VT),to explore treatment strategies and to prognostic characteristics,and to provide diagnostic and therapeutic references for TFE3-VT patients.Methods:Patients who underwent surgery at Department of Urology,Peking University Third Hospital from January 2013 to January 2024 were enrolled,including three cohorts:Pathologically confirmed TFE3-VT patients,TFE3-RCC patients without VT(TFE3-non-VT),and non-TFE3-rearranged renal cell carcinoma patients with VT(non-TFE3-VT).Clinical history,imaging data,pathological data,and follow-up records were collected.Primary and secondary endpoints were progression-free survival(PFS)and overall survival(OS),respectively.(1)Baseline characteristics were compared between the TFE3-VT and TFE3-non-VT patients.Normally distributed continuous variables were expressed as mean±SD and compared using Student's t-test;non-normally distributed variables were expressed as M(P25,P75)and analyzed with Mann-Whitney U test;categorical variables were described as frequency and percentage[n(％)]and compared by x2 test or Fisher's exact test.(2)Clinical history,radiological presenta-tions,surgical data,and histopathological features of the TFE3-VT patients were comprehensively charac-terized.(3)Survival analysis was performed for the TFE3-VT patients.Follow-up data of the TFE3-VT patients were described in detail,and their survival outcomes were compared with the TFE3-non-VT and non-TFE3-VT patients.When compared with the TFE3-non-VT counterparts,Kaplan-Meier method was used to generate PFS and OS curves among:(1)the TFE3-RCC patients across clinical stages Ⅰ-Ⅳ;(2)TFE3-VT versus TFE3-non-VT cohorts;(3)stage Ⅲ subgroups of the TFE3-VT and TFE3-non-VT patients.Intergroup survival differences were statistically evaluated using Log-rank tests.For comparisons with the non-TFE3-VT patients,a 1∶1 propensity score matching(PSM)was implemented to balance baseline characteristics between the two cohorts.Post-matching Kaplan-Meier curves were generated to compare PFS and OS between the matched groups,with Log-rank tests employed to determine statistical significance of survival disparities.All statistical analyses were conducted with R software(v 4.2.3),and two-tailed P＜0.05 was considered statistically significant.Results:The study included 45 TFE3-RCC patients:13 TFE3-VT and 32 TFE3-non-VT cases.Additionally,523 non-TFE3-VT patients were enrolled.Among the 13 TFE3-VT patients,9 were female(69.2％)and 4 male(30.8％),with a mean age of(37.9±14.4)years,mean BMI of(22.2±3.5)kg/m2,median age-adjusted Charlson comorbidity index(aCCI)of 1.0(0.0,1.0),and preoperative creatinine level of(75.3±15.9)μmol/L;tumors were located in the left kidney in 7 patients(53.8％)and right kidney in 6(46.2％);preoperative distant metastasis(M1 stage)was present in 6 patients(46.2％),while 7(53.8％)showed no metastasis;VT distribution by Mayo level comprised 7 cases(53.8％)at level 0,1 case each at levels Ⅰ and Ⅳ(7.7％respectively),and 2 cases each at levels Ⅱ and Ⅲ(15.4％respectively);surgical approaches comprised open surgery(n=2,15.4％),laparoscopic surgery(n=6,46.1％),and robot-assisted laparoscopic surgery(n=5,38.5％);mean operative time was(273±79)min,and intraoperative blood loss was(722±570)mL;mean maximum tumor diameter was(10.8±2.4)cm.All the 13 patients underwent TFE3 protein immunohistochemistry(IHC)staining,with 7 confirmed by fluorescence in situ hybridization(FISH).Tumor recurrence or metastasis occurred in 11 patients(84.6％),and 9(69.2％)patients died during follow-up.Median PFS was 4 months(1 year PFS rate:31％),and median OS was 13 months(1 year OS rate:54％).Survival analysis of 45 TFE3-RCC pa-tients revealed statistically significant differences in PFS and OS across all the clinical stages(P＜0.001).The TFE3-VT patients exhibited significantly worse PFS and OS than the TFE3-non-VT patients(P＜0.001),with persistent significance in stage Ⅲ subgroup analysis(P＜0.05).After PSM,TFE3-VT pa-tients showed significantly inferior PFS compared with non-TFE3-VT(P=0.01),though no significant difference was shown between the OS curves(P=0.11).Conclusion:TFE3-VT predominantly occurs in young females with frequent preoperative metastases.Strongly-positive staining of TFE3 protein in IHC stai-ning and red-green split signals in FISH tests are reliable diagnostic markers.TFE3-VT patients exhibit in-ferior survival compared with TFE3-non-VT patients and earlier progression than non-TFE3-VT patients.

Objective:To evaluate the long-term oncological outcomes of partial nephrectomy(PN)in patients with renal cell carcinoma(RCC)who were clinically staged as clinical T1(cT1)preoperatively but upstaged to pathological T3a(pT3a)after surgery.Methods:A total of 427 RCC patients postopera-tively diagnosed as pT3aN0M0 at Peking University Third Hospital from February 2013 to December 2022 were retrospectively reviewed.Among them,33 cT1 patients upstaged to pT3a RCC received PN(PN group),while 394 non-upstaged pT3a RCC patients underwent radical nephrectomy(RN,RN group).Propensity score matching was performed at a 1∶1 ratio based on baseline characteristics.The Kaplan-Meier method was used to assess overall survival(OS),cancer-specific survival(CSS),and disease-free survival(DFS),with Log-rank tests and Cox regression models for multivariate analysis.Results:Before matching,the PN group(n=33)had significantly higher rates of perirenal fat invasion(PFI,45.5％vs.15.2％)and segmental renal vein involvement(42.4％vs.20.8％),but lower rates of renal sinus invasion(RSI,21.2％vs.73.6％)and renal vein tumor thrombus(0％vs.15.2％)compared with the RN group(n=394,all P＜0.05).After matching,baseline characteristics were comparable between the PN group(n=33)and RN group(n=33).No significant differences were observed in operative time,blood loss,mean hospital stay,complication rate,positive margin rate,or conversion to open surgery between the two groups(P＞0.05).However,the PN group showed significantly higher estimated glomerular filtration rate(eGFR)postoperatively[76.9(55.4,87.3)mL/(min·1.73 m2)vs.61.7(56.8,73.5)mL/(min·1.73 m2),P＜0.05],indicating better renal function preserva-tion.No significant differences were found in OS,CSS,or DFS between the groups(P＞0.05).Multi-variate ana-lysis identified renal vein invasion(RVI),higher Fuhrman grades(Ⅲ-Ⅳ),and sarcoma-toid differentiation as independent risk factors for DFS and CSS in the pT3a RCC patients(P＜0.05).Conclusion:For cT1 RCC patients upstaged to pT3a,PN preserves renal function more effectively while achieving com-parable oncological outcomes to RN.RVI,higher Fuhrmann grade,and sarcomatoid differentiation are independent risk factors for pT3N0M0 RCC patients.

Objective The study aimedto investigate the effects and metabolic mechanisms of Gegen Qinlian Decoction(GQD)containing serum on hypoxia-induced glucose metabolism in L02 cells.Methods The effects of five hypoxia durations(6,12,18,24,and 48 hours)on glucose consumption and cell viability of L02 cells were examined under hypoxic conditions to determine the optimal hypoxia time.Normal hepatocytes served as the normal control group.L02 cells with hypoxia-induced reduction in glucose consumption were divided into several groups:hypoxia group,metformin 2 mmol/L group,and 25 g/kg GQD groups treated with 5%,10%,and 15%GQD contain-ing serum.Glucose consumption was used as an indicator of drug efficacy.High-resolution liquid chromatography tandem quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS)was employed to collect metabolite signals from each group.Data were analyzed by using Progenesis QI software,and potential biomarkers were identified through online databases such as HMDB.Finally,metabolic pathways of potential biomarkers were analyzed via the Metabo Analyst 5.0 website.Results An 18 hour hypoxia period was identified as the optimal duration for the replication of the hypoxia-induced L02 cell model.GQD containing serums at 5%and 10%significantly increased glucose consumption in hypoxia-induced L02 cells after 18 hours.14 biomarkers of hypoxia-induced L02 cells were identified,with the levels of 13 biomarkers significantly increased and 1 biomarker significantly decreased.GQD containing serum notably regulated the levels of 3 biomarkers.Conclusion GQD containing serum might improve hypoxia-induced abnormal glucose metabolism in L02 cells and enhance glucose consumption by modulating glycero-phospholipid metabolism,glycosylphosphatidylinositol biosynthesis,and sphingolipid metabolism.

MiRNA,as a class of short non-coding RNA molecules,plays an important role in the post-transcriptional regula-tion of gene expression.miRNAs regulate gene expression by targeting specific mRNA sequences,thereby affecting various cellular bio-logical behaviors,including proliferation,apoptosis,migration,and invasion.In recent years,it has been found that miRNA may play an important role in the occurrence and development of hepatocellular carcinoma.This article provides a review of the research progress on the association between miRNA and the occurrence and development of hepatocellular carcinoma.
