ObjectiveTo explore the academic characteristics of contemporary renowned Chinese medicine masters in treating diabetic kidney disease （DKD） from the perspectives of principles， methods， formulas， and medications. MethodsIn strict accordance with the Systematic Review of Text and Opinion （SrTO） process developed by the Joanna Briggs Institute （JBI）， an Australian evidence-based healthcare center， the databases including China National Knowledge Infrastructure （CNKI）， VIP Database， Wanfang Data， and China Biomedical Literature Service System （SinoMed） were searched. Based on predefined inclusion and exclusion criteria， text information extraction， quality evaluation， and text information synthesis were conducted sequentially. The data were analyzed and presented in the form of text and figures. ResultsA total of 215 articles related to 43 contemporary renowned experts in the fields of Chinese medicine nephrology and endocrinology were included. The study found that the academic thoughts of these masters in the treatment of DKD are extensive， involving multiple levels such as disease understanding， therapeutic strategies， formula application， and medication use. In terms of disease understanding， the primary pathogenesis is characterized by deficiency in the root and excess in the manifestation. It is emphasized that internal factors， such as congenital endowment deficiency， interact with external factors such as improper diet， emotional disturbances， invasion of exogenous pathogens， and delayed or inappropriate treatment， to jointly induce the disease. This further gives rise to various pathogenetic theories， including obstruction of renal collaterals by blood stasis， toxin-induced damage to renal collaterals， latent wind disturbing the kidney， and internal heat leading to mass formation. In terms of therapeutic strategies and medication use， the principal treatment method is to replenish Qi and nourish Yin. Stage-based and syndrome-differentiated treatments are advocated. Flexible use of insect-derived drugs and wind-dispelling drugs is emphasized， along with proficiency in applying classical formulas and drug pairs. Integrated internal and external treatments， as well as the combined application of multiple therapeutic approaches， are commonly employed for comprehensive management. Meanwhile， the concept of "preventive treatment of disease" is upheld， and individualized long-term management of patients is advocated. ConclusionThrough the SrTO process， the academic thoughts of contemporary renowned Chinese medicine masters in the treatment of DKD have been systematically and standardly synthesized， providing a scientific and standardized basis for future theoretical exploration.

OBJECTIVE To investigate the equivalence of different decoction processes based on rat model of hypertension with liver-yang hyperactivity. METHODS Inductively coupled plasma mass spectrometry （ICP-MS） was used to compare the dissolution differences of inorganic elements in the powder-directly-decocted decoction versus the pieces-decocted-first decoction of Ostreae Concha- Haliotidis Concha- Margaritifera Concha drug pair. Six SD rats were included in the normal group. The spontaneously hypertensive rats were given Aconite decoction for six weeks to induce the hypertension model with liver-yang hyperactivity. After successful modeling， 48 rats were randomly divided into the model group， the captopril group [positive control， 8 mL/（kg·d） ] ， as well as low-， medium-， and high-dose groups of pieces decocted first or directly powder decocted [2.02， 4.05， 8.10 mL/（kg·d） ] ， with 6 rats in each group. Each group received the corresponding drug or equal volume of pure water intragastrically， once a day， for two consecutive weeks. After the last administration， the degree of irritability， facial temperature， pressure pain threshold， blood pressure， and pathological changes of the thoracic aorta were observed in each group. Serum nitric oxide （NO） and plasma angiotensin Ⅱ （Ang Ⅱ）， renin， and aldosterone （ALD） levels were also measured. RESULTS ICP-MS analysis results showed statistically significant differences in the contents of macroelements Li， Na， Mg， Ca， Mn， Ga， Sr， Mo， Cd， Sn， and Sb， between the powder-directly-decocted decoction and the pieces-decocted-first decoction （ P ＜0.05） ，the elements P， Cr， Fe， Ni， Zn， Hg， Tl， and Pb were not detected in either decoction. Animal experiments showed that after two weeks of administration， compared with the model group， the facial temperature， and blood pressure decreased in all treatment groups， while the pressure pain threshold increased； plasma levels of Ang Ⅱ， renin and ALD， as well as the serum level of NO were all decreased， and thoracic aortic media thickness was significantly reduced， most of the differences in the above indicators were statistically significant （ P ＜0.05 or P ＜0.01 or P ＜0.001）. Pathological observation showed improvement in thoracic aortic pathological injury. CONCLUSIONS The powder-directly-decocted process for the Ostreae Concha- Haliotidis Concha- Margaritifera Concha drug pair significantly promotes the dissolution of key elements such as Ca， Mg， and Sr without increasing the dissolution of harmful elements. It is equivalent to the traditional pieces-decocted-first in alleviating liver-yang hyperactivity syndrome， lowering blood pressure， and protecting the vascular endothelium， and even shows better performance in some indicators.

Objective On the basis of the theory of the tumor metastatic state, this work aims to explore the metastasis trajectories and peripheral immune response patterns in patients with non-small cell lung cancer (NSCLC) receiving vital qi-strengthening and toxin-eliminating therapy (Fuzheng Juandu) and reveal the value of peripheral immunity in assessing vital qi deficiency during metastasis. Methods A retrospective study design was adopted. Patients with NSCLC admitted from January 1, 2018, to October 31, 2025 were enrolled. Data on metastasis status and peripheral immune indices were collected at the follow-up time points of one, two, three, and five years. Group-based trajectory modeling was used to fit metastasis trajectories, and the independent predictors of trajectory grouping were analyzed through multifactor and multiclassification logistic regression. Results A total of 184 patients with NSCLC were included, and three different groups of metastasis trajectories were identified, namely, the low-risk stable (46.74%, n=86), low-risk rising (13.59%, n=25), and high-risk stable (39.67%, n=73) groups. Univariate analysis revealed substantial differences in peripheral immune indices among the three trajectory groups. Multivariate analysis showed that TNM stage, absolute neutrophil count, lymphocyte count, absolute monocyte count, platelet volume, SAA:CRP ratio, and NLR were independent predictors of the low-risk rising group, whereas TNM stage, absolute monocyte count, basophil count, SII, and NLR were independent predictors of the high-risk stable group. Conclusion Under Fuzheng Juandu therapy, patients with NSCLC exhibit three distinct metastasis trajectories, each corresponding to a specific peripheral immune response pattern. Elucidating these peripheral immune response patterns may facilitate the objective quantification of the degree of vital qi deficiency, prediction of future metastasis risk, and providing an important reference for the individualized clinical implementation of Fuzheng Juandu therapy.

ObjectiveTo evaluate whether the use of intrapartum ultrasound （IPUS） to monitor the labor process， as alternative method of traditional vaginal examination （VE）， could reduce the incidence of postpartum complications associated with vaginal delivery. MethodsA total of 360 primiparas who underwent cervical dilation balloon induction of labor （IOL） and achieved successful vaginal delivery after childbirth at the Third Affiliated Hospital of Sun Yat-sen University between January 2022 and December 2023， were included in the retrospective study with half assessed for labor progress using IPUS （n=180） and the other half using VE （n=180）. The differences in the relevant indicators of the labor process and the complications of vaginal delivery were compared between the two groups of pregnant women. ResultsThere was no significant difference in the duration of membrane rupture， the first stage of labor and the second stage of labor between the two groups. However， the number of VE in the IPUS group was significantly lower ［nulliparous： 4 （3-4） vs. 6 （5-8）， P＜0.001； multiparous： 2 （2-3） vs. 4 （3-5）， P＜0.001］. The IPUS group experienced a lower incidence of postpartum fever compared to the VE group ［1.67%（3/180） vs. 7.22%（13/180）， P=0.006］， while other complications of vaginal delivery， such as fever during labor， postpartum hemorrhage （PPH）， laceration， poor wound healing and uroschesis， were not significantly different （all P ＞ 0.05）. The logistic regression analysis confirmed that the use of IPUS served as a protective factor for postpartum fever with an OR of 0.06 ［95% CI （0.01， 0.36）； P=0.002］， while the duration of membrane rupture was a risk factor ［OR： 1.12； 95% CI （1.03， 1.22）； P = 0.011］. ConclusionsIPUS， as an alternative to traditional VE， does not affect the progress of labor. However， it can significantly reduce the frequency of VE and the incidence of postpartum fever， thereby facilitating the rapid recovery of postpartum women， which makes it clinically valuable for application.

Objective:To investigate the effect of human epidermal growth factor receptor 2 (HER2) on bladder cancer by regulating phosphoinositide 3-kinase (PI3K)-protein kinase B (Akt) signaling pathway via tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein epsilon peptide (YWHAE) and to examine its mechanism.Methods:The gene expression profiling interactive analysis (GEPIA) database was used to analyze HER2 expression in 408 bladder cancer tissues and 19 adjacent normal tissues. HER2 expression was then compared between 215 tumor protein 53 ( TP53) mutant and 193 TP53 non-mutant bladder cancer tissues. Tissue samples were obtained from patients who underwent surgical resection for bladder cancer in Tianjin Medical University General Hospital between June 2010 and March 2015. Immunohistochemistry and Western blotting were performed to validate HER2 and p53 protein expression, as well as analyze their correlation. Bladder cancer T24 cells were transfected with short hairpin RNA targeting HER2 (shHER2) control (shCon) or shHER2, designated as shCon and shHER2 groups. Bladder cancer UMUC3 cells were transfected with overexpression control (oeCon), HER2 overexpression (oeHER2), oeYWHAE, or short hairpin RNA targeting murine double minute 2 (MDM2) (shMDM2), and were designated as the oeCon, oeHER2, oeYWHAE and shMDM2 groups, respectively. UMUC3 cells were then treated with either 0.1% dimethyl sulfoxide or 100 mmol/L dihydrotestosterone and designated as the solvent control and dihydrotestosterone groups, respectively. Additionally, oeCon and oeYWHAE UMUC3 cells were treated with the PI3K inhibitor LY294002 (25 μmol/L), designated as the LY294002 and LY294002+oeYWHAE groups. On this basis, shHER2 was transfected into the oeCon and oeYWHAE groups, which were then designated as the shHER2-2 and shHER2-2+oeYWHAE groups. The relative expression levels of HER2, YWHAE mRNA, and HER2, p53, YWHAE, MDM2, phosphorylated Akt (p-Akt), and Akt proteins were determined using quantitative reverse transcription PCR and Western blotting. Cell Counting Kit-8, Transwell, and wound-healing assays were performed to evaluate the impact of HER2 on the proliferation, invasion, and migration of bladder cancer cells. Mass spectrometry and co-immunoprecipitation assays were performed to confirm the interaction between YWHAE and HER2, and immunofluorescence was used to detect p53 expression. BALB/c nude mice were subcutaneously injected with 5×10 6 UMUC3 cells in the scapular region. According to the random number table method, they were divided into negative the control group and the transfection group, with 3 mice in each group, and transfected with oeCon and oeHER2, respectively. Tumor volume and weight were measured and calculated, and HER2 and p53 protein expression in bladder cancer tissues was validated by immunohistochemistry and Western blotting. Independent sample t test or Mann-Whitney U test was used to compare the two groups. One-way analysis of variance or Kruskal-Wallis test was used for comparison of multiple groups. Results:GEPIA database analysis demonstrated significantly higher levels of HER2 expression in bladder cancer tissues and in TP53 mutant bladder cancers compared with adjacent normal tissues (both P<0.01). HER2 expression was inversely correlated with p53 expression ( r=?0.6). Immunohistochemistry and Western blotting confirmed that p53 expression level in the bladder cancer tissues (5.32±0.11) was higher than that in the adjacent normal tissues (2.00±0.01), while HER2 expression level in the bladder cancer tissues (1.13±0.02) was lower than that in the adjacent normal tissues (6.20±0.06) (both P<0.01). HER2 mRNA and protein expression, absorbance at 450 nm wavelength ( A450) values, and cell invasion number and cell migration distance in the shHER2 group were all lower than those in the shCon group [0.25±0.01 vs 1.00±0.05, 1.00± 0.01 vs 3.26±0.09, 1.36±0.04 vs 1.65±0.06, (107.00±5.51) vs (202.70±11.61) cells, and (298.70±6.94) vs (454.30±7.84) μm] ( P<0.05, 0.01). HER2 mRNA and protein expression, absorbance ( A450) values, and cell invasion number and cell migration distance in the oeHER2 group were all higher than those in the oeCon group [0.78±0.02 vs 0.46±0.01, 2.05±0.02 vs 1.00±0.00, 1.23±0.06 vs 0.78±0.03, (136.30±5.24) vs (59.00±5.51) cells, and (153.70±7.27) vs (66.33±33.84) μm] ( P<0.05, 0.01). HER2 protein expression level in the dihydrotestosterone group was higher than that in the solvent control (1.83±0.19 vs 1.00±0.00), while p53 protein expression level in the dihydrotestosterone group was lower than that in the solvent control group (1.10±0.10 vs 1.53±0.15) (both P<0.01). The differentially expressed protein between the dihydrotestosterone group and solvent control group was YWHAE. The expression levels of YWHAE mRNA and protein in the dihydrotestosterone group (1.10±0.12 and 3.05±0.03) were higher than those in the solvent control group (0.30±0.12 and 1.00±0.00) (both P<0.01). YWHAE protein expression level in the oeHER2 group was higher than that in the oeCon group (1.37±0.08 vs 1.00±0.00) ( P<0.01) and YWHAE expression level in the bladder cancer tissues was higher than that in the adjacent normal tissues ( P<0.01). YWHAE expression positively correlated with HER2 expression ( r=0.4). Co-immunoprecipitation confirmed direct binding between HER2 and YWHAE. Overexpression of YWHAE significantly reduced p53 expression. The relative expression level of MDM2 protein in the oeYWHAE group (2.73±0.09) was lower than that in the oeCon group (3.43±0.12) ( P<0.01). The relative expression level of MDM2 protein in the shMDM2 group (1.00±0.00) was lower than that in the oeYWHAE group, and the relative expression level of p53 protein (2.00±0.00) was higher than that in the oeYWHAE group (1.07±0.07) (both P<0.01). The relative expression levels of YWHAE and p-Akt protein in the oeYWHAE group (1.23±0.09, 3.00±0.06) were higher than those in the oeCon group (1.00±0.00, 1.13±0.03) ( P<0.05, 0.01). The relative expression level of p-Akt protein in LY294002 group (2.20±0.06) was lower than that in the oeCon group (3.30±0.10), and the relative expression level of p53 protein (2.10±0.06) was higher than that in the oeCon group (1.00±0.00) (both P<0.01). The relative expression level of p-Akt protein in LY294002+oeYWHAE group (2.00±0.06) was lower than that in the oeYWHAE group (3.53±0.14), and the relative expression level of p53 protein (2.10±0.06) was higher than that in the oeYWHAE group (1.00±0.06) (both P<0.01). The relative expression levels levels of YWHAE, p-Akt and MDM2 protein in the shHER2-2 group (1.60±0.15, 1.70±0.06, 0.80±0.06) were lower than those in the oeCon group (2.30±0.06, 2.30±0.06, 1.13±0.09), and the relative expression level of p53 protein (1.83±0.12) was higher than that in the oeCon group (1.00±0.00) ( P<0.05, 0.01). The relative expression level of YWHAE protein in the shHER2-2+oeYWHAE group (2.00±0.06) was lower than that in the oeCon group ( P<0.01), and the relative expression levels of MDM2 and p53 protein (2.63±0.15, 1.13±0.03) were higher than those in the oeCon group ( P<0.05, 0.01). The tumor volume, tumor weight, and relative expression levels of HER2, YWHAE, p-Akt, and MDM2 proteins on day 28 in the transfection group [(5 133.0±185.6) mm 3, (0.65±0.12) g, 2.23±0.02, 4.00±0.12, 3.33±0.06 and 2.24±0.02] were higher than those in the negative control group [(2 633.0±88.2) mm 3, (0.33±0.07) g, 0.98±0.02, 1.27±0.03, 1.29±0.02 and 1.46±0.06] (all P<0.01). The relative expression level of p53 protein (1.21±0.04) was lower than that in the negative control group (3.29±0.04) ( P<0.01). Conclusions:HER2 may promote the malignant progression of bladder cancer by regulating the PI3K-Akt pathway via YWHAE, thereby facilitating MDM2 nuclear translocation and p53 degradation. This ultimately enhances the proliferative, migratory, and invasive capacities of bladder cancer cells.

Objective The kinetic parameters of Lin's squeezing-pressing adjustment manipulation were collected for the analysis of its mechanical characteristics,thus to establish a standardized operating procedure to guide clinical teaching of this technique.Methods Ten healthy male trainees(aged 20-30 years)from the Tuina Department of Guangdong Provincial of Chinese Medicine were selected as the subjects.A multi-point thin-film pressure testing system was used to collect mechanical parameters during the operation of Lin's squeezing-pressing adjustment manipulation.The mechanical characteristics were analyzed,and then a mathematical model of time-mechanics curve was constructed.Results(1)The kinetic parameters of Lin's squeezing-pressing adjustment manipulation were as follows:preload force averaged(279.45±19.36)N with a duration of(0.98±0.03)s,the valley value of preload force averaged(137.45±3.59)N,the maximum impact force was(495.56±7.33)N,the impact duration averaged(0.15±0.01)s,the impact velocity averaged(3 183.96±94.76)N/s,and the impulse was(57.16±1.82)N/s.(2)The fitting function of impact force showed large absolute values for both ascending and descending slopes,and the ascending slope was significantly greater than the descending slope,indicating that the Lin's manipulation stressed on rapid outburst of the strength and withdrawal of the strength.(3)One-way ANOVA revealed no statistically significant differences in the preload force and its duration and valley value,the maximum impact force,and impact time among different operators(P＞0.05).Conclusion The analysis of kinetic parameters demonstrates that skilled operators maintain relatively stable mechanical parameters when performing Lin's squeezing-pressing adjustment manipulation.This study provides a preliminary digital analysis of the mechanical characteristics of Lin's bone-setting manipulation in addressing"bone misalignment and tendon displacement",which supplies objective evaluation criteria for the technique.

ObjectiveTo investigate the perceived experience and acceptance of intrapartum ultrasound （IPUS） as a novel method for labor progress assessment among pregnant women. MethodsFrom February 2023 to December 2024， a total of 180 pregnant women admitted to the Labor Ward of Lingnan Hospital， the Third Affiliated Hospital of Sun Yat-sen University， who were planned for vaginal trial of labor ， were accessed for labor progress using IPUS and vaginal examination （VE） after the onset of labor and prior to the initiation n of labor analgesia. A self-designed questionnaire was used to investigate the women's perceived experiences with both examination methods and their acceptance of IPUS. The pain intensity associated with the examinations was evaluated using the visual analogue pain scale （VAS）. Differences in the women's experiences and pain intensity between the two labor progress assessment methods were compared. ResultsThe acceptance rate of IPUS was 96.67% （174/180）， with the remaining 6 cases undecided. Over 60% of the pregnant women reported IPUS assessment as comfortable and none of them felt discomfort， whereas 32.8% felt uncomfortable with VE （χ²=196.02， P＜0.001）. Nearly two-thirds of the pregnant women believed that VE would cause psychological distress， while none reported such effect with IPUS （χ²=261.52， P＜0.001）. Approximately 77.78% （140/180） of the pregnant women believed that IPUS could reduce their fear of vaginal delivery and enhance their confidence if it replaced VE. The VAS score for IPUS ［0 （0， 2）］ was significantly lower than that for VE ［4 （4， 6）］ （Z=-14.62， P＜0.001）. Further stratified analysis showed that over 90% （164/180） of the pregnant women found IPUS painless， with no moderate or severe pain reported， compared to 43.33% （78/180） experienced moderate or severe pain with VE （P＜0.001）. ConclusionAs a novel approach for labor progress assessment， IPUS not only alleviates the pain and discomfort associated with traditional VE and reduces the fear of childbirth but also enhances women's confidence in delivery， thereby achieving a high level of acceptance among parturient women in China.

Objective: To explore the safety and feasibility of the disconnection of the left renal artery preferentially during robot-assisted inferior vena cava (IVC) thrombectomy for patients with left renal cell carcinoma and tumor emboli. Methods: Clinical data of 7 patients who underwent robot-assisted IVC thrombectomy and radical nephrectomy in the First Affiliated Hospital of Zhengzhou University during Dec.2021 and Oct.2024 were retrospectively analyzed.Thrombectomy was performed first，followed by nephrectomy. The “IVC-first, kidney-last”robotic technique was developed to minimize chances of IVC thrombus. When patients in left lateral decubitus position, the left renal artery was severed from the right side through the inferior vena cava and abdominal aorta. After removal of thrombus from IVC was completed, patients changed to the right lateral position to complete radical left nephrectomy. Results: Imaging examinations revealed that the median diameter of the renal cell carcinomas was 83(46-99) mm; the median length of the inferior vena cava cancerous emboli was 49(2-91) mm.According to the Mayo classification，the cancerous emboli were gradeⅠ in 2 cases，gradeⅡ in 4 cases，and grade Ⅲ in 1 case.All surgeries were successful.The median operation time was 248(201-331) minutes，blood loss 500(200-1000) mL，and 6 cases required intraoperative blood transfusion.The median time for transition into the intensive care unit was 1(1-4) days，and drainage tube removal 6(5-12) days.Serum creatinine increased significantly in 5 cases，4 of which returned to normal after 1 week，but 1 had renal insufficiency (creatinine 166 μmol/L).Chylous fistula occurred in 1 patient，and lower extremity venous thrombosis developed in 3 patients.Pathological examinations indicated 6 cases of renal cell carcinoma and 1 case of MiT family translocation renal cell carcinoma.During the median follow-up of 17(1-35) months，5 cases were tumor-free，while 2 had lung and retroperitoneal metastases.They received targeted therapy of axitinib combined immunotheraphy and lived with tumors. Conclusion: In the left lateral position for left renal cell carcinoma with cancerous emboli，robot-assisted laparoscopic thrombectomy by crossing the inferior vena cava and abdominal aorta and disconnecting the left renal artery first is safe and feasible.

Objective To investigate the correlation of vascular senescence indicators,brachial-ankle pulse wave velocity(baPWV),cardio-ankle vascular index(CAVI),ankle-brachial index(ABI)with total burden of MRI in patients with cerebral small vessel disease(CSVD).Methods A total of 200 CSVD patients admitted to our hospital from November 2023 to October 2024 were retrospectively recruited,and based on their total MRI burden,they were divided into a low-burden group(score:0-1,103 cases)and a high-burden group(score:2-4,97 cases).A athero-sclerosis monitoring device(VS-1500A)was used to detect baPWV,CAVI,and ABI values.The relationships of the three indicators with total MRI burden score and their predictive values for the burden score were analyzed.Results The high-burden group had significantly higher BMI,el-evated homocysteine and uric acid levels,and increased baPWV and CAVI,but lower ABI than the low-burden group(P＜0.01).Multivariate logistic analysis showed that baPWV,CAVI and ABI were independent influencing factors for high MRI burden of CSVD patients.Spearman correlation analysis showed that baPWV and CAVI values were positively correlated(r=0.589,P=0.000;r=0.458,P=0.000),and ABI was negatively correlated with the total MRI burden score of CSVD patients(r=-0.352,P=0.000).ROC curve analysis showed that baPWV(AUC=0.816,P=0.000),CAVI(AUC=0.725,P=0.000)and ABI(AUC=0.676,P=0.000)were all predic-tors for high MRI burden score in CSVD patients.Conclusion baPWV and CAVI are positively,and ABI is negatively correlated with the total MRI burden score of CSVD patients.baPWV,CAVI and ABI show higher predictive value for the high burden score,with baPWV most significant.
